HIV screening in men and women in Senegal: coverage and associated factors; analysis of the 2017 demographic and health survey

Understanding the mechanisms of antimicrobial resistance and potential therapeutic approaches against the Gram-negative pathogen Acinetobacter baumannii

Globally, the emergence of anti-microbial resistance in pathogens has become a serious threat to human health and well-being. Infections caused by drug-resistant microorganisms in hospitals are associated with increased morbidity, mortality, and healthcare costs. Acinetobacter baumannii is a Gram-negative bacterium belonging to the ESKAPE group and is widely associated with nosocomial infections. It persists in hospitals and survives antibiotic treatment, prompting acute infections such as urinary tract infections, pneumonia, bacteremia, meningitis, and wound-related infections. An innovation void in drug discovery and the lack of new therapeutic measures against A. baumannii continue to afflict infection control against the rising drug-resistant cases. The emergence of drug-resistant A. baumannii strains has also led to the incessant collapse of newly discovered antibiotics. Therefore exploring novel strategies is requisite to give impetus to A. baumannii drug discovery. The present review discusses the bacterial research community's efforts in the field of A. baumannii, focusing on the strategies adapted to identify potent scaffolds and novel targets to bolster and diversify the chemical space available for drug discovery. Firstly, we have discussed existing chemotherapy and various anti-microbial resistance mechanisms in A. baumannii bacterial strains. Next, we elaborate on multidisciplinary approaches and strategies that may be the way forward to combat the current menace caused by the drug-resistant A. baumannii strains. The review highlights the recent advances in drug discovery, including combinational therapy, high-throughput screening, drug repurposing, nanotechnology, and anti-microbial peptides, which are imperative tools to fight bacterial pathogens in the future.

Pooled prevalence of malaria and associated factors among vulnerable populations in Ethiopia: a systematic review and meta-analysis

BACKGROUND

Malaria is a serious, fatal disease, and a high-risk determinant for human health globally. Children, pregnant women, and migrants are vulnerable groups for malaria infection in African regions. Recently, malaria is an endemic disease in Ethiopia.

OBJECTIVES

This study aimed to determine the pooled prevalence of malaria and its determinant factors among the most vulnerable populations in Ethiopia.

METHODS

Electronic databases, including PubMed, Google Scholar, Web of Science, Semantic Scholar, and Scopus were used for searching articles published since the 2020 Gregorian calendar and onwards. All peer-reviewed Ethiopian journals, health institutions, and Universities were considered for article searching. A PRISMA flow chart and Endnote software were used for article screening, and to remove duplications, respectively. The modified version of the Newcastle-Ottawa Scale was used for potential risk of bias assessments. The heterogeneity among the included studies was evaluated using the indicator of heterogeneity (I2). Egger's test and funnel plot were used to examine the possible publication bias. A random-effects analysis was used to assess the pooled prevalence of malaria, and its determinant factors with a 95% CI. The screening process, data extraction, and quality assessment were done independently, and any disagreements were resolved through discussions.

RESULTS

A total of twelve studies were included in this study. The pooled malaria prevalence was 11.10% (95% CI: 6.10, 16.11). Stagnant water (AOR: 4.19, 95% CI: 2.47, 7.11), no insecticide-treated net utilization (AOR: 3.15, 95% CI: 1.73, 5.73), and staying outdoors at night (AOR: 5.19, 95% CI: 2.08, 12.94) were the pooled estimated statistically risk factors for malaria prevalence. Whereas, insecticide-treated bed net utilization (AOR: 1.59, 95% CI: 0.23, 10.95) reduces the risk of malaria infection.

CONCLUSIONS

The pooled prevalence of malaria is high among vulnerable populations. Creating awareness regarding utilization of insecticide-treated bed nets, and draining stagnant water from the environment are possible interventions to reduce the prevalence of malaria.

Factors influencing HIV testing uptake in Sub-Saharan Africa: a comprehensive multi-level analysis using demographic and health survey data (2015-2022)

BACKGROUND

Human Immunodeficiency Virus (HIV) is a global health concern, causing over 35 million deaths, with 97% occurring in developing nations, particularly impacting Sub-Saharan Africa. While HIV testing is crucial for early treatment and prevention, existing research often focuses on specific groups, neglecting general adult testing rates. This study aims to identify predictors of HIV testing uptake among adults in Sub-Saharan Africa.

METHOD

Data were obtained from the official Demographic and Health Survey program database, which used a multistage cluster sampling technique to collect the survey data. In this study, a weighted sample of 283,936 adults was included from thirteen Sub-Saharan African countries. Multilevel multivariable logistic regression analysis was employed to identify predictors of HIV testing uptake. Akaike's information criteria guided model selection. Adjusted odds ratios and corresponding 95% confidence intervals determined significant predictor variables.

RESULT

Among adults in Sub-Saharan African countries, the prevalence of HIV testing uptake was 65.01% [95% CI (64.84%, 65.17%)]. Influential factors included male sex [AOR: 0.51, 95% CI (0.49,0.53)], varying odds ratios across age groups (20-24 [AOR: 3.3, 95% CI (3.21, 3.46) ], 25-29 [AOR: 4.4, 95% CI (4.23, 4.65)], 30-34 [AOR: 4.6, 95%CI (4.40, 4.87)], 35-39 [AOR: 4.0, 95%CI (3.82, 4.24)], 40-44 [AOR: 3.7, 95%CI (3.50, 3.91)], 45-49 [AOR: 2.7, 95%CI (2.55, 2.87)], 50+ [AOR: 2.7, 95%CI (2.50, 2.92)]), marital status (married [AOR: 3.3, 95%CI (3.16, 3.46)], cohabiting [AOR: 3.1, 95% CI (2.91, 3.28)], widowed/separated/divorced [AOR: 3.4, 95%CI (3.22, 3.63)]), female household headship (AOR: 1.28, 95%CI (1.24, 1.33)), education levels (primary [AOR: 3.9, 95%CI (3.72, 4.07)], secondary [AOR: 5.4, 95%CI (5.16, 5.74)], higher [AOR: 8.0, 95%CI (7.27, 8.71)]), media exposure (AOR: 1.4, 95%CI (1.32, 1.43)), wealth index (middle [AOR: 1.20, 95%CI (1.17, 1.27)], richer [AOR: 1.50, 95%CI (1.45, 1.62)]), Having discriminatory attitudes towards PLWHIV [AOR: 0.4; 95% CI (0.33, 0.37)], had multiple sexual partners [AOR: 1.2; 95% CI (1.11, 1.28)], had comprehensive knowledge about HIV [AOR: 1.6; 95% CI (1.55, 1.67)], rural residence (AOR: 1.4, 95%CI (1.28, 1.45)), and lower community illiteracy (AOR: 1.4, 95%CI (1.31, 1.50)) significantly influenced HIV testing uptake in the region.

CONCLUSION

This study highlights the need for tailored interventions to address disparities in HIV testing uptake among adults in Sub-Saharan Africa and progress towards the achievement of 95-95-95 targets by 2030. Thus, tailored interventions addressing key factors are crucial for enhancing testing accessibility and emphasizing awareness campaigns, easy service access, and targeted education efforts to improve early diagnosis, treatment, and HIV prevention in the region.

Sexual orientation, gender identity and virologic failure among people with HIV: a cohort study in all of US research program

BACKGROUND

Sexual and gender minorities (SGMs) are at higher risk of HIV incidence compared to their heterosexual cisgender counterparts. Despite the high HIV disease burden among SGMs, there was limited data on whether they are at higher risk of virologic failure, which may lead to potential disease progression and increased transmission risk. The All of Us (AoU) Research Program, a national community-engaged program aiming to improve health and facilitate health equity in the United States by partnering with one million participants, provides a promising resource for identifying a diverse and large volunteer TGD cohort. Leveraging various data sources available through AoU, the current study aims to explore the association between sexual orientation and gender identity (SOGI) and longitudinal virologic failure among adult people with HIV (PWH) in the US.

METHODS

This retrospective cohort study used integrated electronic health records (EHR) and self-reported survey data from the All of Us (AoU) controlled tier data, version 7, which includes participants enrolled in the AoU research program from May 31, 2017, to July 1, 2022. Based on participants' sexual orientation, gender identity, and sex assigned at birth, their SOGI were categorized into six groups, including cisgender heterosexual women, cisgender heterosexual men, cisgender sexual minority women, cisgender sexual minority men, gender minority people assigned female at birth of any sexual orientation, and gender minority people assigned male at birth of any sexual orientation. Yearly virologic failure was defined yearly after one's first viral load testing, and individuals with at least one viral load test > 50 copies/mL during a year were defined as having virologic failure at that year. Generalized linear mixed-effects models were used to explore the association between SOGI and longitudinal virologic failure while adjusting for potential confounders, including age, race, ethnicity, education attainment, income, and insurance type.

RESULTS

A total of 1,546 eligible PWH were extracted from the AoU database, among whom 1,196 (77.36%) had at least one viral failure and 773 (50.00%) belonged to SGMs. Compared to cisgender heterosexual women, cisgender sexual minority women (adjusted Odds Ratio [aOR] = 1.85, 95% CI: 1.05-3.27) were at higher risk of HIV virologic failure. Additionally, PWH who were Black vs. White (aOR = 2.15, 95% CI: 1.52-3.04) and whose insurance type was Medicaid vs. Private insurance (aOR = 2.07, 95% CI: 1.33-3.21) were more likely to experience virologic failure.

CONCLUSIONS

Maintaining frequent viral load monitoring among sexual minority women with HIV is warranted because it allows early detection of virologic failure, which could provide opportunities for interventions to strengthen treatment adherence and prevent HIV transmission. To understand the specific needs of subgroups of SGMs, future research needs to examine the mechanisms for SOGI-based disparities in virologic failure and the combined effects of multi-level psychosocial and health behavior characteristics.

Perceived access to social support during and after TB treatment in Mbeya and Songwe regions, Tanzania: perspectives from TB patients and survivors set against health care providers

Introduction

Pulmonary tuberculosis (PTB) remains a life-threatening disease in Tanzania, with negative physical, financial, economic and psychosocial consequences to individuals and the society. It mainly lowers the quality of life of patients, survivors and their families, especially those in the poorest and socially deprived categories.

Objectives

To report and discuss a qualitative study that assessed the nature of social support desired and received by PTB patients and survivors. Participants were given a chance to share their experiences and their perceptions on whether the social support they desired had an impact on their treatment-seeking behaviour and treatment adherence.

Methods

Face-to-face interviews were conducted with the three aforementioned groups, purposively selected at a TB clinic between October 2020 and March 2021. The questions covered topics related to the types of social support desired and the sources of support during and after treatment, if any. Interviews were concluded until no new information was obtained. Data analysis was facilitated using NVivo 12 software.

Results

Participants pointed out a need for psychosocial, financial, and material support during and after treatment. However, they sometimes miss support from family/household members or the rest of the community. Because of this experience, they lived with difficulties, facing hardships when required to pay out of pocket for transport during the care-seeking. Survivors testified experience of a denial of support by even their close relatives who regarded them as no longer needing it after recovering. Patients and survivors also reported experience of social isolation as they were believed able to transmit PTB infections. Limited psychological support at the contacted TB clinics was another experience reported. TB clinic staff's experiences confirmed almost all the experiences shared by their clients. With limited support, resilience and self-care were identified as key mechanisms for coping.

Conclusion

Complete recovery from PTB is possible, but reverting to a normal life is difficult without social support. Policies and programs need to increase opportunities for social support for TB patients and survivors. Doing so is likely to improve TB-related treatment, care-seeking practices, and adherence.

A multilevel analysis of the determinants of HIV testing among men in Sub-Saharan Africa: Evidence from Demographic and Health Surveys across 10 African countries

Sub-Saharan Africa, the epicenter of the HIV epidemic, has seen significant reductions in new infections over the last decade. Although most new infections have been reported among women, particularly adolescent girls, men are still disadvantaged in accessing HIV testing, care, and treatment services. Globally, men have relatively poorer HIV testing, care, and treatment indices when compared with women. Gender norms and the associated concept of masculinity, strength, and stereotypes have been highlighted as hindering men's acceptance of HIV counseling and testing. Therefore, men's suboptimal uptake of HIV testing services will continue limiting efforts to achieve HIV epidemic control. Thus, this study aimed to identify individual, neighborhood, and country-level determinants of sub-optimal HIV testing among men in Sub-Saharan African countries. We analyzed demographic and health datasets from surveys conducted between 2016 and 2020 in Sub-Saharan African Countries. We conducted multivariable multilevel regression analysis on 52,641 men aged 15-49 years resident in 4,587 clusters across 10 countries. The primary outcome variable was ever tested for HIV. HIV testing services uptake among men in these ten Sub-Saharan African countries was 35.1%, with a high of 65.5% in Rwanda to a low of 10.2% in Guinea. HIV testing services uptake was more likely in men with increasing age, some form of formal education, in employment, ever married, and residents in relatively wealthier households. We also found that men who possessed health insurance, had some form of weekly media exposure, and had accessed the internet were more likely to have ever received an HIV test. Unlike those noted to be less likely to have ever received an HIV test if they had discriminatory attitudes towards HIV, comprehensive HIV knowledge, recent sexual activity, and risky sexual behavior were positive predictors of HIV testing services uptake among men. Furthermore, men in communities with high rurality and illiteracy were less likely to receive an HIV test. Individual and community-level factors influence the uptake of HIV testing among Sub-Saharan African men. There was evidence of geographical clustering in HIV testing uptake among men at the community level, with about two-thirds of the variability attributable to community-level factors. Therefore, HIV testing programs will need to design interventions that ensure equal access to HIV testing services informed by neighborhood socioeconomic conditions, peculiarities, and contexts.

Therapeutic drug monitoring of six contraindicated/co-administered drugs by simple and green RP-HPLC-PDA; application to spiked human plasma

Therapeutic drug monitoring is an important clinical testing of the drugs to monitor their concentrations in plasma in order to guarantee their optimal impact, and to avoid any side effects resulting from drug-drug interactions. A green reversed-phase high-performance liquid chromatographic method using a photodiode array detector (RP-HPLC-PDA) was developed for the simultaneous determination of three carbapenem antibiotics (Imipenem, ertapenem, and meropenem) with the co-formulated drug (cilastatin) and contraindicated drugs (probenecid and warfarin) in spiked human plasma. The separation was achieved at 25 °C using a gradient elution of a mixture of mobile phase A: methanol and mobile phase B: phosphate buffer (pH 3.0). The photodiode array detector was adjusted at 220 nm. Bioanalytical method validation was carried out as per the FDA guidelines, and the method showed good linearity ranges for the six drugs that included their Cmax levels along with low limits of quantification. Based on the results, the method was found to be accurate and precise; with high % recovery and good % RSD, respectively. The method was successfully applied to spiked human plasma, signifying a good potential to be implemented in future TDM studies of these drugs when co-administered together.

Machine learning prediction of adolescent HIV testing services in Ethiopia

Background

Despite endeavors to achieve the Joint United Nations Programme on HIV/AIDS 95-95-95 fast track targets established in 2014 for HIV prevention, progress has fallen short. Hence, it is imperative to identify factors that can serve as predictors of an adolescent's HIV status. This identification would enable the implementation of targeted screening interventions and the enhancement of healthcare services. Our primary objective was to identify these predictors to facilitate the improvement of HIV testing services for adolescents in Ethiopia.

Methods

A study was conducted by utilizing eight different machine learning techniques to develop models using demographic and health data from 4,502 adolescent respondents. The dataset consisted of 31 variables and variable selection was done using different selection methods. To train and validate the models, the data was randomly split into 80% for training and validation, and 20% for testing. The algorithms were evaluated, and the one with the highest accuracy and mean f1 score was selected for further training using the most predictive variables.

Results

The J48 decision tree algorithm has proven to be remarkably successful in accurately detecting HIV positivity, outperforming seven other algorithms with an impressive accuracy rate of 81.29% and a Receiver Operating Characteristic (ROC) curve of 86.3%. The algorithm owes its success to its remarkable capability to identify crucial predictor features, with the top five being age, knowledge of HIV testing locations, age at first sexual encounter, recent sexual activity, and exposure to family planning. Interestingly, the model's performance witnessed a significant improvement when utilizing only twenty variables as opposed to including all variables.

Conclusion

Our research findings indicate that the J48 decision tree algorithm, when combined with demographic and health-related data, is a highly effective tool for identifying potential predictors of HIV testing. This approach allows us to accurately predict which adolescents are at a high risk of infection, enabling the implementation of targeted screening strategies for early detection and intervention. To improve the testing status of adolescents in the country, we recommend considering demographic factors such as age, age at first sexual encounter, exposure to family planning, recent sexual activity, and other identified predictors.

Adenovirus and Mycoplasma pneumoniae co-infection as a risk factor for severe community-acquired pneumonia in children

Background

To investigate the pathogenic characteristics and risk factors of pediatric severe community-acquired pneumonia (CAP).

Methods

We retrospectively analyzed the clinical data of hospitalized children with severe CAP from April 2014 to June 2019 in China. Data of age, sex and pathogenic results were collected: bacterial and fungal cultures, respiratory viruses from sputum or bronchoalveolar lavage fluid (BALF), serum Mycoplasma pneumoniae (MP)-IgM and Chlamydia Pneumoniae-IgM, and BALF or blood (1-3)-β-D-glucan/galactomannan test.

Results

A total of 679 children with severe CAP were included in the analysis. The number of cases infected with MP was higher in males than in females. There were significant differences between the ≤1-year and >1-year groups in terms of pathogen. The top three bacteria cultured were Haemophilus influenzae (57/679, 8.4%), Streptococcus pneumoniae (50/679, 7.4%), and Pseudomonas aeruginosa (25/679, 3.7%). The top three viruses detected were adenovirus (AdV, 124/679, 18.3%), respiratory syncytial virus (24/679, 3.5%), and parainfluenza virus (21/679, 3.1%). AdV and MP were the leading pathogens, detected in 18.3% and 32.6% cases, respectively. MP infection increased the risk of AdV infection (OR 3.77, p < 0.0001). MP infection was a risk factor for severe AdV-infected pneumonia, while sex, age, bacteria, Chlamydia Pneumoniae, fungal, and AdV infections were risk factors for severe MP-infected pneumonia.

Conclusions

AdV and MP were dominant pathogens in children with severe CAP. AdV and MP infection predisposed each other to develop severe illness. AdV-MP co-infection may lead to severe pneumonia.

Factors associated with HIV testing among pregnant women in Rwanda: A nationwide cross-sectional survey

Human immunodeficiency virus (HIV) testing during pregnancy is crucial for the prevention of mother-to-child transmission of HIV, through aiding prompt treatment, care, and support. However, few studies have explored HIV testing among pregnant women in Rwanda. This study, therefore, aimed to determine the prevalence and associated factors of HIV testing among pregnant women in Rwanda. We used secondary data from the 2020 Rwanda Demographic and Health Survey (RDHS), comprising 870 pregnant women. Multistage stratified sampling was used by the RDHS team to select participants. We conducted bivariable and multivariable logistic regression to explore factors associated with HIV testing using SPSS (version 25). Of the 870 pregnant women, 94.0% had tested for HIV during their current pregnancy. Younger age (24-34 years), not working, large household size, multiple sex partners, as well as secondary, primary, and no education were associated with higher odds of HIV testing compared to their respective counterparts. However, being unmarried, belonging to the western region, having not visited a health facility, and not having comprehensive HIV knowledge were associated with lower odds of HIV testing. A high proportion of pregnant women had tested for HIV. The study revealed that individual-level factors had the greatest influence on HIV testing in pregnancy, with a few household-level factors showing significance. There is a need for maternal health stakeholders to design and develop HIV testing programs that are region-sensitive. These programs should target older, more educated, working, and unmarried women with limited HIV knowledge.

Species distribution and antifungal susceptibility profiles of yeasts isolated from onychomycosis: a cross-sectional study with insights into emerging species

Candida onychomycosis is a common fungal infection affecting the nails, primarily caused by Candida (C.) species. Regarding the increasing trend of Candida onychomycosis and the antifungal resistant phenomenon in recent years, this study aims to evaluate the epidemiological characteristics of Candida onychomycosis, the distribution of emerging species, and the antifungal susceptibility profiles of isolates. Onychomycosis caused by yeast species was confirmed through direct examination and culture of nail scraping among all individuals suspected to have onychomycosis and referred to a medical mycology laboratory between June 2019 and March 2022. Species of yeast isolates were identified using the multiplex PCR and PCR-RFLP methods. The antifungal susceptibility of isolates to common antifungal agents and imidazole drugs was evaluated according to the M-27-A3 CLSI protocol. Among 101 yeast strains isolated from onychomycosis, Candida parapsilosis complex (50.49%) was the most common species, followed by C. albicans (20.79%) and C. tropicalis (10.89%). Rare species of yeasts such as C. guilliermondii and Saccharomyces cerevisiae were also identified by molecular methods. Results obtained from antifungal susceptibility testing showed significant differences in MIC values of isoconazole, fenticonazole, and sertaconazole among different species. Overall, a fluconazole-resistant rate of 3% was found among Candida species. Moreover, there was a statistically significant difference in MICs of fenticonazole and clotrimazole between the two most prevalent causative species, C. parapsilosis complex and C. albicans. Correct identification of the causative agents of onychomycosis and performing susceptibility testing could be helpful in choosing the most appropriate antifungal therapy.

Synergistic Antimicrobial Activity of Eugenol in Combination with Fosfomycin to Combat Escherichia coli and Potential Effect on Plasmid-Mediated Fosfomycin Resistance Genes

The presence of multidrug-resistant pathogenic microorganisms makes it challenging to cure bacterial illnesses. Syzygium aromaticum has been used for medicinal purposes since ancient times. The objective of this study was to investigate the potential synergistic effect of the combination of Eugenol and Fosfomycin against clinically Uropathogenic Escherichia coli (UPEC) and their possible co-treatment as well as their contribution to plasmid-mediated Fosfomycin resistance (fosA3 and fosA4) genes using molecular assays. Eugenol was extracted from clove (Syzygium aromaticum) plants using steam distillation by Clevenger and analyzed by high-performance liquid chromatography (HPLC). UPEC accounted for 63.6 % of all isolates. Specifically, 99.3 % of the UPEC isolates exhibited resistance to multiple types of antibiotics [multidrug-resistant (MDR)]. The MIC for Eugenol was 1.25-5 μg/mL, and Fosfomycin was 512-1024 μg/mL, while the MBC for Eugenol was 5-10 μg/mL and Fosfomycin was 2048 μg/mL. The synergistic effects were considerable, with 1/4 MIC of Eugenol resulting in 1/8 MIC Fosfomycin. Eugenol inhibited most of the UPEC isolates at 4-8 hours, Fosfomycin at 8-12 hours, and co-treatment at 4-8 hours. The fosA3 and fosA4 genes were detected in 5.7 % and 2.9 % of the isolates, respectively. The results showed variable gene expression changes in response to the different treatments.

Understanding the association of mass media with the timing of antenatal care in Ethiopia: an impression from the 2016 Ethiopia demographic and health survey

INTRODUCTION

Although the timing of antenatal care has a high potential of reducing maternal and child health problems and can be improved through different mass media exposure, it has been overlooked and remained a major life-costing delinquent issue. Therefore, the aim of this study is to identify the relationship between mass media exposure and ANC for further insight.

METHODS

We used the 2016 Ethiopian Health and Demography (EDHS) data. EDHS is a community-based cross-sectional survey that applies a two-stage stratified cluster sampling and it is a country-representative. We included 4740 reproductive-age women with complete records in EDHS dataset in this study. We excluded records with missing data from the analysis. We used ordinal logistic regression followed by generalized ordinal logistic to examine mass media relationships with timely antenatal care (ANC). We presented data using numbers, mean, standard deviations, percent or proportions, coefficient of regression, and 95% confidence interval. All analyses were performed using STATA version 15.

RESULT

We examined the data of 4740 participants for the history of timely initiation of ANC and found 32.69% (95% CI = 31.34, 34.03) timely ANC. Factors such as watching television (TV) less than once a week [coef. = -0.72, CI: -1.04, -0.38], watching TV at least once a week [coef. = -0.60, CI: -0.84, -0.36], listening to radio [coef. = -0.38, CI: -0.84, -0.25], and use internet every day[coef. = -1.37, CI: -2.65, -0.09], are associated with the timely ANC.

CONCLUSION

Despite its association with improving the timing of ANC, our findings showed mothers need additional support on the use of the media and the timing of ANC. In addition to the mass media, other covariates such as educational status, family size, and husband's desire affected the timely ANC imitation. These need attention during implementation to avert the current. This is also an essential input for policy and decision-makers.

Fluoroquinolone resistance determinants in carbapenem-resistant Escherichia coli isolated from urine clinical samples in Thailand

Background

Escherichia coli is the most common cause of urinary tract infections and has fluoroquinolone (FQ)-resistant strains, which are a worldwide concern.

Objectives

To characterize FQ-resistant determinants among 103 carbapenem-resistant E. coli (CREc) urinary isolates using WGS.

Methods

Antimicrobial susceptibility, biofilm formation, and short-read sequencing were applied to these isolates. Complete genome sequencing of five CREcs was conducted using short- and long-read platforms.

Results

ST410 (50.49%) was the predominant ST, followed by ST405 (12.62%) and ST361 (11.65%). Clermont phylogroup C (54.37%) was the most frequent. The genes NDM-5 (74.76%) and CTX-M-15 (71.84%) were the most identified. Most CREcs were resistant to ciprofloxacin (97.09%) and levofloxacin (94.17%), whereas their resistance rate to nitrofurantoin was 33.98%. Frequently, the gene aac(6')-Ib (57.28%) was found and the coexistence of aac(6')-Ib and blaCTX-M-15 was the most widely predominant. All isolates carried the gyrA mutants of S83L and D87N. In 12.62% of the isolates, the coexistence was detected of gyrA, gyrB, parC, and parE mutations. Furthermore, the five urinary CREc-complete genomes revealed that blaNDM-5 or blaNDM-3 were located on two plasmid Inc types, comprising IncFI (60%, 3/5) and IncFI/IncQ (40%, 2/5). In addition, both plasmid types carried other resistance genes, such as blaOXA-1, blaCTX-M-15, blaTEM-1B, and aac(6')-Ib. Notably, the IncFI plasmid in one isolate carried three copies of the blaNDM-5 gene.

Conclusions

This study showed FQ-resistant determinants in urinary CREc isolates that could be a warning sign to adopt efficient strategies or new control policies to prevent further spread and to help in monitoring this microorganism.

Machine learning-based time series models for effective CO2 emission prediction in India

China, India, and the USA are the countries with the highest energy consumption and CO2 emissions globally. As per the report of datacommons.org , CO2 emission in India is 1.80 metric tons per capita, which is harmful to living beings, so this paper presents India's detrimental CO2 emission effect with the prediction of CO2 emission for the next 10 years based on univariate time-series data from 1980 to 2019. We have used three statistical models; autoregressive-integrated moving average (ARIMA) model, seasonal autoregressive-integrated moving average with exogenous factors (SARIMAX) model, and the Holt-Winters model, two machine learning models, i.e., linear regression and random forest model and a deep learning-based long short-term memory (LSTM) model. This paper brings together a variety of models and allows us to work on data prediction. The performance analysis shows that LSTM, SARIMAX, and Holt-Winters are the three most accurate models among the six models based on nine performance metrics. Results conclude that LSTM is the best model for CO2 emission prediction with the 3.101% MAPE value, 60.635 RMSE value, 28.898 MedAE value, and along with other performance metrics. A comparative study also concludes the same. Therefore, the deep learning-based LSTM model is suggested as one of the most appropriate models for CO2 emission prediction.

Uptake and Persistence on HIV Pre-Exposure Prophylaxis Among Female Sex Workers and Men Having Sex with Men in Kigali, Rwanda: A Retrospective Cross-Sectional Study Design

Background

Although HIV pre-exposure prophylaxis (PrEP) is known for its effectiveness in preventing HIV transmission; there is a global rise in HIV infection rates, particularly prominent in sub-Saharan Africa. This health concern is mostly evident among high-risk groups, namely Female Sex Workers (FSWs) and Men who have Sex with Men (MSMs), both of whom are more susceptible to sexually transmissible infections. This research examined the persistence, uptake, and associated predictors of PrEP utilization within the FSW and MSM populations.

Methods

A cross-sectional study design was conducted involving 4872 individuals from the FSW and MSM groups who were enrolled in a PrEP program across 10 health centers participating in a pilot initiative. The study population was subject to a year-long follow-up period commencing on March 1st, 2019. To evaluate the determinants of PrEP utilization within FSW and MSM groups, bivariate logistic analyses and multivariate logistic regression models were employed.

Results

The findings revealed that the occurrence of PrEP uptake was 45.55% (n=2219) among FSWs and 35.42% (n=17 participants) among MSM. Regarding PrEP persistence, MSM (88.24%, n=15 participants) presented higher PrEP proportion than FSWs (78.5%, n=1742 women). Our findings disclosed that individuals aged 25-34 years (aOR=0.82; 95% CI=0.72-0.93, p=0.002), 35-44 years (aOR=0.83; 95% CI=0.71-0.97, p=0.017), and 55 years and older (OR=0.14; 95% CI=0.04-0.48, p=0.002) exhibited lower likelihoods of having low PrEP uptake than those aged 15-19 years. Moreover, individuals residing with their families (aOR=0.71; 95% CI=0.58-0.87, p<0.001), living with roommates (aOR=0.7; 95% CI=0.5-0.97, p=0.032) displayed lower odds for experiencing low PrEP uptake than their counterparts living alone.

Conclusion

This study highlighted the low uptake of PrEP among participants when compared to previous studies. These results revealed significant influences of age and living conditions on PrEP usage.

Chest computed tomography severity score is a reliable predictor of mortality in patients with chronic obstructive pulmonary disease co-infected with COVID-19

BACKGROUND

Coronavirus disease 2019 (COVID-19) pandemic is considered a global health crisis. The data related to chronic obstructive pulmonary disease (COPD) patients with COVID-19 are incomplete, especially the findings of the chest computed tomography (CT). The aim of the current study was to investigate the severity of the disease of COVID-19 in patients with COPD based on CT severity score and to evaluate its predictive power in the mortality of patients.

METHODS

In a retrospective study, demographic, clinical, and CT scan findings of COPD patients with COVID-19 were extracted from March 2020 to February 2022. CT severity score was determined based on the extent and nature of involvement of lungs in CT scan findings. By performing receiver operating characteristics (ROC) and Kaplan-Meier survival analysis were determined the disease severity and survival probability.

RESULTS

The most frequent radiological findings in chest CT scan included ground glass opacities (89.3%), consolidations (51.8%), crazy-paving pattern (46.4%), and septal thickening (35.7%). The mean CT severity score of deceased patients (34.61 ± 18.73) was significantly higher than recovered patients (16.71 ± 14.01, p < 0.001). Based on the ROC and Kaplan-Meier survival curves, it was revealed that CT severity score was a valuable criteria in the diagnosis of mortality in COPD patients with COVID-19.

CONCLUSION

The findings of this study revealed that the CT severity scoring in COPD patients with COVID-19 was valuable in identifying poor prognosis, although further studies are needed.

Predictive Factors of Mortality in Patients with Severe COVID-19 Treated in the Intensive Care Unit: A Single-Center Study in Vietnam

INTRODUCTION

The fourth outbreak of COVID-19 with the delta variant in Vietnam was very fierce due to the limited availability of vaccines and the lack of healthcare resources. During that period, the high mortality of patients with severe and critical COVID-19 caused many concerns for the health system, especially the intensive care units. This study aimed to analyze the predictive factors of death and survival in patients with severe and critical COVID-19.

METHODS

We conducted a cross-sectional and descriptive study on 151 patients with severe and critical COVID-19 hospitalized in the Intensive Care Unit of Binh Duong General Hospital.

RESULTS

Common clinical symptoms of severe and critical COVID-19 included shortness of breath (97.4%), fatigue (89.4%), cough (76.8%), chest pain (47.7%), loss of smell (48.3%), loss of taste (39.1%), and headache (21.2%). The abnormal biochemical features were leukopenia (2.1%), anemia, thrombocytopenia (18%), hypoxia with low PaO2 (34.6%), hypocapnia with reduced PaCO2 (29.6%), and blood acidosis (18.4%). Common complications during hospitalization were septic shock (15.2%), cardiogenic shock (5.3%), and embolism (2.6%). The predictive factors of death were being female, age > 65 years, cardiovascular comorbidity, thrombocytopenia (< 137.109/l), and hypoxia at inclusion or after the first week or blood acidosis (pH < 7.28). The use of a high dose of corticosteroids reduced the mortality during the first 3 weeks of hospitalization but significantly increased risk of death after 3 and 4 weeks.

CONCLUSIONS

Common clinical symptoms, laboratory features, and death-related complications of critical and severe COVID-19 patients were found in Vietnamese patients during the fourth wave of the COVID-19 pandemic. The results of this study provide new insight into the predictive factors of mortality for patients with severe and critical COVID-19.

Reassortment and genomic analysis of a G9P[8]-E2 rotavirus isolated in China

OBJECTIVE

To isolate a prevalent G9P[8] group A rotavirus (RVA) (N4006) in China and investigate its genomic and evolutionary characteristics, with the goal of facilitating the development of a new rotavirus vaccine.

METHODS

The RVA G9P[8] genotype from a diarrhea sample was passaged in MA104 cells. The virus was evaluated by TEM, polyacrylamide gel electrophoresis, and indirect immunofluorescence assay. The complete genome of virus was obtained by RT-PCR and sequencing. The genomic and evolutionary characteristics of the virus were evaluated by nucleic acid sequence analysis with MEGA ver. 5.0.5 and DNASTAR software. The neutralizing epitopes of VP7 and VP4 (VP5* and VP8*) were analyzed using BioEdit ver. 7.0.9.0 and PyMOL ver. 2.5.2.

RESULTS

The RVA N4006 (G9P[8] genotype) was adapted in MA104 cells with a high titer (105.5 PFU/mL). Whole-genome sequence analysis showed N4006 to be a reassortant rotavirus of Wa-like G9P[8] RVA and the NSP4 gene of DS-1-like G2P[4] RVA, with the genotype constellation G9-P[8]-I1-R1-C1-M1-A1-N1-T1-E2-H1 (G9P[8]-E2). Phylogenetic analysis indicated that N4006 had a common ancestor with Japanese G9P[8]-E2 rotavirus. Neutralizing epitope analysis showed that VP7, VP5*, and VP8* of N4006 had low homology with vaccine viruses of the same genotype and marked differences with vaccine viruses of other genotypes.

CONCLUSION

The RVA G9P[8] genotype with the G9-P[8]-I1-R1-C1-M1-A1-N1-T1-E2-H1 (G9P[8]-E2) constellation predominates in China and may originate from reassortment between Japanese G9P[8] with Japanese DS-1-like G2P[4] rotaviruses. The antigenic variation of N4006 with the vaccine virus necessitates an evaluation of the effect of the rotavirus vaccine on G9P[8]-E2 genotype rotavirus.

Patient satisfaction with antiretroviral therapy service provided by pharmacists in Dembia district health institutions, Northwest Ethiopia

BACKGROUND

The patients' perception of the health service is a vital tool for measuring health service quality. Besides, Patient satisfaction is an essential feature in assessing the quality of health services. Health institution leaders are considering quantifiable patient satisfaction data as a means to evaluate the health care service.

METHOD

An institution-based cross-sectional study was employed from 21/8/2022 to 21/9/2022 among 308 patients attending ART pharmacy services in three health institutions of Dembia distinct. Data were collected by using a questionnaire and reviewing medical charts. Results were calculated and presented in the form of texts, tables, and graphs. Variables with a p-value of 0.05 were considered significant determinants of patient satisfaction.

RESULT

A total of 308 HIV patients were recruited with a response rate of 100%. The overall prevalence of satisfaction among respondents was 231(75%). Being unable to read and write [1.21(AOR = 1.07-4.31)] and patient age greater than 48 years 1.9(0.73-2.59) were significantly associated with the level of patient satisfaction. Among the participants 66.9% were satisfied with clear and organized service, and 76% were satisfied with the convenience of a private counseling room.

CONCLUSION

The general patient satisfaction at the antiretroviral therapy clinic did not achieve the national target of 85% satisfaction with significant differences among health centers. Being educated to a higher level, absence of signs and directions to ART clinics, and not having the opportunity to ask questions were the factors influencing patient satisfaction with ART service.

Assessing secular trends in HIV rapid diagnostic test uptake and positivity in Northeast Iran, a country in MENA region; ingredients for target-specific prevention policies

BACKGROUND

Iran is amongst the first three countries in Middle East and North Africa (MENA) region where two-thirds of region's new HIV infections are reported. HIV testing at the population level is key to interrupting the HIV transmission chain. The current study aimed to evaluate the history of HIV rapid diagnostic testing (HIV-RDT) and its correlates in northeast Iran.

METHODS

In this cross-sectional study, de-identified records of HIV-RDTs were extracted by the census method from the electronic health information system of 122 testing facilities between 2017 and 2021. Descriptive, bivariate, and multiple logistic regression analyses were performed to identify the factors associated with HIV-RDT uptake and risks and drivers of HIV-RDT positivity, separately among men and women.

RESULTS

Conducting 66,548 HIV-RDTs among clients with a mean age of 30.31 years, 63% female, 75.2% married, and 78.5% with high school education or below, yielded 312 (0.47%) positive results. Test uptake was comparatively low among men and the unmarried sub-population. Prenatal care and high-risk heterosexual intercourse were the most frequent reasons for taking HIV-RDT among women and men, respectively (76% and 61.2%). High-risk heterosexual contact, tattooing, mother-to-child transmission (MTCT), having a partner at risk of HIV infection, and injecting drugs were test seekers' most reported transmission routes. One-third of the newly-infected female clients were identified through prenatal testing. Multivariate analysis revealed older age at the time of testing (Adjusted Odd Ratio (AOR) = 1.03), divorce (AOR = 2.10), widowhood (AOR = 4.33), education level of secondary school (AOR = 4.67), and unemployment (AOR = 3.20) as significant demographic predictors of positive HIV-RDT (P-value < 0.05). However, clients' nationality, testing history, duration of HIV exposure, and reported reasons for taking HIV-RDT were not associated with the test result (P-value > 0.05).

CONCLUSION

Innovative strategies are required to scale up test uptake and positive yields among the key population in the region. The current evidence strongly suggests implementing gender-targeted strategies, according to the differences in demographic and behavioral risk between men and women.

HQDCNet: Hybrid Quantum Dilated Convolution Neural Network for detecting covid-19 in the context of Big Data Analytics

Medical care services are changing to address problems with the development of big data frameworks as a result of the widespread use of big data analytics. Covid illness has recently been one of the leading causes of death in people. Since then, related input chest X-ray image for diagnosing COVID illness have been enhanced by diagnostic tools. Big data technological breakthroughs provide a fantastic option for reducing contagious Covid disease. To increase the model's confidence, it is necessary to integrate a large number of training sets, however handling the data may be difficult. With the development of big data technology, a unique method to identify and categorise covid illness is now found in this research. In order to manage incoming big data, a massive volume of chest x-ray images is gathered and analysed using a distributed computing server built on the Hadoop framework. In order to group identical groups in the input x-ray images, which in turn segments the dominating portions of an image, the fuzzy empowered weighted k-means algorithm is then employed. A hybrid quantum dilated convolution neural network is suggested to classify various kinds of covid instances, and a Black Widow-based Moth Flame is also shown to improve the performance of the classifier pattern. The performance analysis of COVID-19 detection makes use of the COVID-19 radiography dataset. The suggested HQDCNet approach has an accuracy of 99.01. The experimental results are evaluated in Python using performance metrics such as accuracy, precision, recall, f-measure, and loss function.

Prevalence of syphilis and associated factors among female sex workers in Ethiopia: findings from a multilevel analysis of a national bio-behavioral survey

BACKGROUND

Syphilis is a highly contagious sexually transmitted infection posing a significant public health challenge, especially in developing countries, including sub-Saharan Africa. Female sex workers are exposed to sexually transmitted infections, including syphilis, because of their sexual behavior and limited access to health services. However, data on national syphilis prevalence estimates and the associated factors are scarce in Ethiopia. This, as well as our limited knowledge about the extent of clustering among female sex workers in the country, is a critical gap in information we aimed to fill through this analysis.

METHODS

The study was a cross-sectional, bio-behavioral survey conducted among female sex workers in six cities and ten major towns in Ethiopia. Participants were selected using a respondent-driven sampling method. Survey participants provided blood samples for syphilis, HIV, and hepatitis serological testing. Survey data were collected via an interviewer-administered questionnaire. In this analysis, we employed descriptive statistics to summarize data on the study variables. In addition, we used multilevel bivariable and multivariable logistic regression models to examine the association between independent variables and the dependent variable (syphilis prevalence) while accounting for the clustering effect.

RESULT

A total of 6085 female sex workers participated in the survey. Their median age [Interquartile Range (IQR) was 25 (8)] years, and a majority (96.1%) were in the 20-24-year-old age group. The prevalence of syphilis among female sex workers in Ethiopia's six cities and ten major towns was 6.2%. Being in the age group of 30-34 (AOR = 2.64; 95% CI = 1.40, 4.98) and 35-59 (AOR = 4.7; 95% CI = 2.5, 8.86), being divorced/widowed (AOR = 1.37; 95% CI = 1.03, 1.82), having no formal education (AOR = 3.38; 95% CI = 2.34, 5.11), primary 1st cycle (grades 1-4) education (AOR = 2.77; 95% CI = 1.79, 4.30), and having primary 2nd cycle (grades 5-8) education (AOR = 1.80; 95% CI = 1.21, 2.69) were significantly associated with syphilis among female sex workers.

CONCLUSION

The prevalence of syphilis among female sex workers was high. Being divorced/widowed or in the older age group and having a low level of education were significantly associated with an increased risk of syphilis. The high prevalence and associated factors identified need to be considered in planning comprehensive interventions to control syphilis among female sex workers in Ethiopia.

High prevalence of β-lactam and fluoroquinolone resistance in various phylotypes of Escherichia coli isolates from urinary tract infections in Jiroft city, Iran

BACKGROUND

Urinary tract infection (UTI) is one of the most prevalent infectious diseases with worldwide health threatening. Antimicrobial resistant strains of Escherichia coli (E. coli) are a common cause of UTI which were identified as a treatment challenge. This study aimed to assay the prevalence of common β-lactam resistance genes including blaTEM, blaSHV, blaCTX-M and blaCMY and phenotypic resistance to commonly used β-lactam and fluoroquinolone antibiotics in UTIs. These factors were evaluated in various phylogenetic groups (phylotypes) of E. coli isolates. Real-time PCR was applied to detect β-lactam resistance genes and conventional PCR was used to determine the phylotypes. Phenotypic resistance against β-lactams (ceftazidime, cefotaxime, aztreonam and ceftriaxone) and fluoroquinolones (ciprofloxacin) were identified by the disc diffusion technique. The ability of extended spectrum β-lactamases (ESBLs) production in E. coli isolates was detected using the combined disc diffusion method.

RESULTS

The prevalence of resistance genes were 89.6% for blaTEM, 44.3% for blaCTX-M, 6.6% for blaSHV and 0.9% for blaCMY. The two high prevalent phylotypes were B2 (29.2%) and D (17.9%) followed by E (14.1%), F (9.4%), C (6.6%) and 10.3% of isolates were unknown in phylotyping. Disc diffusion results showed high prevalence of antibiotic resistance to cefotaxime (88.6%), aztreonam (83%), ceftireaxon (77.3%), ceftazidime (76.4%) and ciprofloxacin (55.6%). Totally, 52.8% of isolates were found as phenotypical ESBL-producers.

CONCLUSIONS

This study's results confirmed an explosion of antibiotic resistance amongst E. coli isolates from UTI against β-lactams and fluoroquinolones. Findings explain the necessity of deep changes in quantity and quality of drug resistance diagnosis and antibiotic therapy strategies. More studies are suggested to better and confident evaluations.

Utilization of mental health services in relation to the intention to reduce chemsex behavior among clients from an integrated sexual health services center in Taiwan

INTRODUCTION

The intention of chemsex-practicing gay and bisexual men and other men who have sex with men (GBMSM) to reduce their drug use is an important factor for the utilization of harm reduction services. This study aimed to examine data from an integrated sexual health services center to understand the relationship between the intention to reduce chemsex behavior and chemsex-related utilization of mental health services among GBMSM who engage in chemsex.

METHOD

We used data collected from Healing, Empowerment, Recovery of Chemsex (HERO), an integrated health center in Taiwan, between November 2017 and December 2021. As the baseline, clients were asked to rate the current and ideal proportions of their sexual activities that involved the use of MDMA, ketamine, methamphetamine, GHB/GBL, or mephedrone. Having the intention to reduce chemsex was defined as having a lower proportion of ideal engagement compared to actual engagement. The data on the use of the services provided at HERO were linked to the survey responses and compared to information gathered during regular follow-up visits. Univariable and multivariable logistic regression analyses and a Poisson regression analysis were performed on the data.

RESULTS

A total of 152 GBMSM reported engaging in chemsex, of whom 105 (69.1%) expressed the intention to reduce their chemsex behavior. Service utilization ranged from 23.0% for participating in meetings of a chemsex recovery group, 17.1% for visiting a mental health clinic, and 10.5% for using both of these services. The intention to reduce chemsex behavior significantly associated with visiting a mental health clinic (aOR = 4.68, p < 0.05), but its association with attending meetings of a chemsex recovery group was only marginally significant (aOR = 2.96, p < 0.1). Other factors that remained significantly associated with service use were a high frequency of substance use and living with HIV.

CONCLUSION

Comprehensive harm reduction strategies, which touch on mental health, drug use management and recovery, are needed for those who want to reduce their chemsex behavior. Public health practitioners should endeavor to raise awareness of resources that are available for people who engage in chemsex and to minimize the barriers blocking their access to the appropriate services.

Failure to Attain HIV Viral Suppression After Intensified Adherence Counselling-What Can We Learn About Its Factors?

Background

Introduction and expansion of antiretroviral therapy (ART) have turned the tide of HIV pandemic, thus helping people living with HIV (PLHIV) achieve viral suppression. This success may need to be complemented by intensified adherence counseling (IAC) to improve adherence to treatment. However, some PLHIV still face higher than acceptable viral loads despite being on treatment.

Purpose

We investigated the factors associated with the failure to suppress HIV viral load after three months of IAC sessions.

Patients and Methods

This cross-sectional study analyzed secondary data from PLHIV-attended care and treatment clinics in Mwanza between January 2018 and December 2019 who had unsuppressed VL after being on ART for at least six months. We identified PLHIV in first-line ART with viral load evaluation before receiving IAC and had viral load results done at 90 days after IAC. We conducted descriptive statistics to examine the magnitude of viral suppression. Wilcoxon signed-rank test used to compare the median viral load before and after IAC sessions, and logistic regressions predicted the factors associated with failure.

Results

This study included 212 subjects. After intervention, most participants 85.9% (182) had significantly improved adherence compared to baseline. More than half 75.5% (160) of the participants had viral suppression after the intervention. Participants aged 18-25 years (AOR = 5.6, 95% CI, 1.1-29.6), unstable client during ART initiation (AOR = 0.3, 95% CI, 0.13-0.62), and poor adherence to ART (AOR = 4, 95% CI, 1.3-12.3) remained the main predictors of virological failure after IAC intervention.

Conclusion

Even though virological suppression is influenced by ART adherence, the findings in this study have shown co-existence of other factors to be addressed. Unstable during ART initiation is a new factor identified in this study.

Factors associated with lifetime HIV testing among women in four Southeast Asian countries: Evidence from the demographic and health surveys

BACKGROUND

Southeast Asian countries have been trying to increase HIV testing coverage of women since awareness of HIV status is essential to eliminate mother-to-child transmission of HIV. This study determined factors related to lifetime HIV testing uptake among women aged 15-49 years in four Southeast Asian countries: Myanmar, Cambodia, the Philippines and Timor-Leste.

METHODS

This study used cross-sectional data from the 2015-16 Myanmar Demographic and Health Survey (DHS), the 2014 Cambodia DHS, the 2017 Philippines National DHS and the 2016 Timor-Leste DHS. We conducted multivariable logistic regression analyses to identify factors associated with lifetime HIV testing among women aged 15-49 years who completed the surveys in each country and ran a fixed effects logistic regression model using pooled data.

RESULTS

The proportions of lifetime HIV testing uptake among women aged 15-49 years were 42.1% in Cambodia, 19.5% in Myanmar, 4.6% in the Philippines, and 3.7% in Timor-Leste. Marital status, age, education, and wealth were significantly associated with lifetime HIV testing uptake among women in all four countries. Other factors (e.g., comprehensive knowledge of HIV, rural/urban residence, positive attitudes towards negotiation for safer sex) were also significant determinants of HIV testing uptake among women in some of these countries.

CONCLUSIONS

A multi-sectoral collaboration of related sectors and organizations is necessary to increase access to HIV testing and HIV knowledge of women to overcome the barriers to HIV testing. It is critical to make HIV testing services available and accessible to women, especially in rural areas.

An overview on the treatments and prevention against COVID-19

BACKGROUND

The coronavirus disease 2019 (COVID-19) caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) continues to plague the world. While COVID-19 is asymptomatic in most individuals, it can cause symptoms like pneumonia, ARDS (acute respiratory distress syndrome), and death in others. Although humans are currently being vaccinated with several COVID-19 candidate vaccines in many countries, however, the world still is relying on hygiene measures, social distancing, and approved drugs.

RESULT

There are many potential therapeutic agents to pharmacologically fight COVID-19: antiviral molecules, recombinant soluble angiotensin-converting enzyme 2 (ACE2), monoclonal antibodies, vaccines, corticosteroids, interferon therapies, and herbal agents. By an understanding of the SARS-CoV-2 structure and its infection mechanisms, several vaccine candidates are under development and some are currently in various phases of clinical trials.

CONCLUSION

This review describes potential therapeutic agents, including antiviral agents, biologic agents, anti-inflammatory agents, and herbal agents in the treatment of COVID-19 patients. In addition to reviewing the vaccine candidates that entered phases 4, 3, and 2/3 clinical trials, this review also discusses the various platforms that are used to develop the vaccine COVID-19.

Asymptomatic nasopharyngeal bacterial carriage, multi-drug resistance pattern and associated factors among primary school children at Debre Berhan town, North Shewa, Ethiopia

BACKGROUND

Nasopharyngeal carriage of bacteria is the main source for transmission of pathogens across individuals and horizontal spread of organisms in the community. It is an important risk factor for the acquisition of community-acquired respiratory tract infection. It is the major public health problem among children. The asymptomatic carriage of nasopharyngeal bacteria is different globally, particularly in Africa, carriage is higher in children and decreases with increasing age, 63.2% in children less than 5 years, 42.6% in children 5-15 years, and 28.0% in adults older than 15 years.

OBJECTIVE

The aims of this study was to determine asymptomatic nasopharyngeal bacterial carriage, multi-drug resistance pattern and associated factors among primary school children at Debre Berhan town, North Shewa, Ethiopia.

METHODS

Institutional based cross-sectional study was conducted at Debre Berhan town primary schools from February 1 to April 30, 2021. Primarily, the schools were stratified into two strata, public and private primary schools. From a total of sixteen government and fourteen private primary schools, five government and five private schools were selected by using a simple random sampling technique. Socio-demographic variables and potential risk factors were assessed using a structured questionnaire. A total of 384 nasopharyngeal swab samples were collected using sterile swabs aseptically; and inoculated on Blood agar, Chocolate agar, MacConkey agar, and Mannitol salt agar. The colony was characterized to isolate bacteria, and bacterial identification was performed by Gram reaction, hemolysis patterns, colonial characteristics and pigmentation, catalase test, coagulase test, mannitol fermentation test, oxidase test, fermentation of carbohydrates, H₂S production, motility, formation of indole, triple sugar iron agar (TSI), citrate utilization, lysine decarboxylase or methyl red vogues proskur utilization, urea hydrolysis and satellitism tests. Antimicrobial sensitivity tests were performed by using modified Kirby-Bauer disk diffusion method. Data were entered into statistical package Epi data 4.0.0.6 and transferred to and analyzed using SPSS software version-23. P value of < 0.05 with Odds ratio (OR) and 95% confidence interval (CIs) was considered as statistically significant.

RESULTS

The overall prevalence of nasopharyngeal carriage of bacterial isolate was 35.7% (95% CI 30.7-40.7%). The predominant isolates were Staphylococcus aureus 54.5% followed by coagulase-negative Staphylococcus 35.8%, and Streptococcus pyogens 4.5%. Most bacterial isolates were susceptible to chloramphenicol, ciprofloxacin, gentamycin, nitrofurantoin, azithromycin, ciprofloxacin; and the overall multidrug resistance pattern of isolated bacteria was 62.03% out of 137 bacterial isolates. Numbers of rooms ≤ 2 per house [AOR = 5.88, 95%CI 1.26-27.57], having history of hospitalization [AOR = 4.08, 95%CI 1.45-11.53], passive smoking [AOR = 4.87, 95%CI 1.49-15.97], family size of > 5 members [AOR = 2.17, 95%CI 1.24-3.81], and number of students in the classroom [AOR = 2.35,95%CI 1.37-4.02] were statistically significant associated risk factors for nasopharyngeal bacteria carriage.

CONCLUSION

Asymptomatic nasopharyngeal bacteria carriage in children is alarming for community-acquired infection. The overall multidrug resistance was very high. The risk of the carriage was increased with having a history of passive smoking, being in large family size and number of students per class. Longitudinal follow-up studies would be helpful for better understanding the infection risk in bacterial pathogen carriers.

Evaluation and Analysis of the Rationality of Clinical Use of Carbapenems in Surgical Departments of a Tertiary Hospital in Southwest China

Purpose

With the increasing frequency and intensity of carbapenem consumption, carbapenem-resistant organisms (CRO) have become a focus of anti-infection research. This study aimed to evaluate the rationality of the clinical use of carbapenems among inpatients in the surgical departments of a tertiary hospital in southwest China.

Patients and methods

A point-score system was established for evaluation based on the clinical practices in surgical departments and selected carbapenem prescriptions from June 2020 to June 2021 for hepatobiliary surgery, gastrointestinal surgery, and neurosurgery in the study hospital. Prescriptions with a total score ≥ 270 were defined as rational. Descriptive statistics were used to describe the characteristics and rationality of the prescriptions. The chi-square test, Mann-Whitney U-test, and Kruskal-Wallis H-test were used to compare characteristics between rational and irrational prescriptions. Linear regression analysis was used to determine the factors affecting the rationality of carbapenem prescriptions.

Results

According to 192 carbapenem prescription records, the median age of patients was 62 years [IQR, 48.0-73.0], and 20% of patients had abdominal infections, 10% had lung infections, 14% had intracranial infections, and 3% had urinary tract infections. 56% of carbapenem prescriptions were irrational. Compared with rational carbapenem prescriptions, irrational prescriptions had a higher proportion of those with inappropriate indications (49% vs 0%, p < 0.05), incorrect variety selection (15% vs 0%, p<0.05), and unreasonable assessment of etiology and efficacy (46% vs 8%, p < 0.05). Linear regression analysis suggested that the diagnosis of cholecystitis (standardized regression coefficient=0.183, p<0.05) and replaced medication (standardized regression coefficient = 0.154, p<0.05) influenced the rationality of carbapenem prescriptions.

Conclusion

Our study shows that the irrational use of carbapenems deserves attention, especially in surgical departments. Interventions for carbapenem use that are based on evaluation criteria should be developed to reduce the emergence and spread of carbapenem-resistant bacteria.

Burden of hepatitis B virus and syphilis co-infections and its impact on HIV treatment outcome in Ethiopia: nationwide community-based study

BACKGROUND

Hepatitis B virus (HBV) and syphilis have been the most common co-infections that hinder treatment outcomes and increase early mortality among people living with human immunodeficiency virus (PLHIV). In this study, we aimed to determine the burden of HBV and syphilis co-infections and its impact on treatment outcomes among PLHIV in Ethiopia.

METHODS

We used data from the Ethiopian Population-based HIV Impact Assessment (EPHIA), which was a household-based national survey in 2017/2018. Human immunodeficiency virus (HIV) testing was done among 19,136 participants using the national testing algorithm and 662 participants (3.50%) were HIV positives who were further tested for viral hepatitis and syphilis co-infections using HBV surface antigen and Chembio DPP syphilis assay, respectively. Viral load, CD4 count and high-sensitivity C-reactive protein (hsCRP) were done to measure HIV treatment outcomes. Descriptive statistics were used to determine the burden of co-infections and a logistic regression model to evaluate the determinants of co-infections using STATA V17.0.

RESULTS

Overall prevalence of HBV and syphilis co-infection was 5.5% and 2.2%, respectively. HBV and syphilis (double co-infection) was 5.9%. The highest prevalence of HBV co-infection was observed among 10-19 years age group (12.9%) and male participants (7.44%) while the highest syphilis co-infection was among people aged ≥50 years (3.5%) followed by age groups 40-49 (3.3%) and 10-19 years (3.2%). Syphilis co-infection was higher among males (5.2%) compared to females (1.1%). After adjusted regression analysis, HBV co-infected PLHIV had higher odds of virologic failure (AOR (95% confidence interval (CI)) = 6.3 (4.2-14.3)), immunosuppression (CD4 count < 500 cells/mm³) (AOR (95%CI) = 2.1(1.3-4.9)) and inflammation (hsCRP >10 mg/dL) (AOR (95%CI) = 9.2(4.3-14.6)). Immunosuppression was also significantly higher among syphilis co-infected PLHIV (AOR (95%CI) = 3.4 (1.3-5.2)).

CONCLUSIONS

Burden of HBV and syphilis co-infections is high particularly among male and adolescent PLHIV and these co-infections hinder virologic and immunologic outcome in Ethiopia. Hence, the program shall enhance HBV and syphilis testing and treatment.

HIV Testing Uptake Among Ethiopian Rural Men: Evidence from 2016 Ethiopian Demography and Health Survey Data

Background

Human immunodeficiency virus (HIV) testing coverage among men remains low in Ethiopia; the problem of limited HIV testing coverage is worst in rural areas. Therefore, this study aims to identify factors associated with HIV testing uptake among rural men in Ethiopia.

Methods

Data from 10,187 rural men was extracted from the 2016 Ethiopian Demography and Health Survey. All analyses were performed using the complex sample analysis procedure to account for the multistage sampling. Bivariable and multivariable regression analyses were performed to identify factors associated with HIV testing uptake. Statistical significance was defined as a 95% Confidence Interval (CI) with a p-value of less than 0.05.

Results

Overall, only 40.3% of rural men have ever been tested for HIV. Being aged 31-44 years (Adjusted Odds Ratio (AOR) =1.12, 95% CI [1.01-1.42]), living in developed regions (AOR=1.43, 95% CI [1.09-1.88]), engaging in non-agricultural activities (AOR = 1.27, 95% CI [1.05-1.52]), being Muslim (AOR = 2.07; 95% CI [1.67-2.67]), having comprehensive knowledge about HIV (AOR =1.31, 95% CI [1.12-1.54]), being from a medium (AOR = 0.56, 95% CI [0.47-0.93]) and rich (AOR = 0.80, 95% CI [0.56-0.80]) households, attending primary (AOR = 0.21, 95% CI [0.16-0.28]) and secondary (AOR = 0.35, 95% CI [0.25-0.35]) school, having their first sexual experience at the age of 17 or younger (AOR = 0.26, 95% CI [0.19-0.93]), having discriminatory attitudes towards HIV patients (AOR = 0.67, 95% CI: 0.47-0.93) and having no health insurance coverage (AOR = 0.54, 95% CI [0.42-0.69]) were significantly associated with HIV testing uptake.

Conclusion

HIV testing uptake among rural men was low. Strengthening awareness programmes on HIV and HIV testing, integrating HIV testing with all other healthcare, strengthening partner accompany and HIV testing during pregnancy and delivery, and providing home-based HIV testing may increase HIV testing uptake.

Health Literacy as a Mediator of the Relationship Between Socioeconomic Position and Pre-Exposure Prophylaxis Uptake Among Men Who Have Sex with Men Living in France

BACKGROUND

In recent decades, several research studies have mentioned a potential mediating effect of health literacy (HL) on the relationship between socioeconomic position and health prevention behaviors. However, no study to date has investigated this hypothesis on HIV prevention behaviors.

OBJECTIVE

The present study aimed to evaluate whether HL mediates the relationship between socioeconomic status (SES) and pre-exposure prophylaxis (PrEP) uptake in men who have sex with men (MSM).

METHODS

The study is based on data collected in the Enquête Rapport au Sexe [report to sex] 2019 survey, an anonymous, self-administered online cross-sectional survey in France conducted between February 16, 2019 and March 31, 2019. Data on education level and perceived financial situation were used as measures of SES, whereas HL was assessed from the Health Literacy Questionnaire's "ability to actively engage with health care providers" scale. Mediation analyses were performed with a model-based causal moderated mediation analysis package in R software. Analyses were adjusted for age, place of residence, marital status, and social support.

KEY RESULTS

The study sample included 13,629 MSM. Median age was 32 years. The majority had an education level higher than upper secondary school (78%) and an adequate HL level (73%). Almost two-thirds perceived their financial situation as comfortable (62%). Overall, PrEP uptake was low (9.5%). The analyses did not show a mediating effect of HL on the relationship between education and PrEP uptake. However, a total mediation effect of HL was observed on the relationship between perceived financial situation and uptake.

CONCLUSIONS

In the context of PrEP uptake, MSM ability to actively engage with health care providers may offset the effect of a difficult financial situation. In the current French context, where PrEP is now also available in general practitioner settings, this result could inform the development of training and support policies for health professionals and the way in which sexual health issues are addressed in consultations.

Spatial distribution and associated factors of measles vaccination among children aged 12-23 months in Ethiopia. A spatial and multilevel analysis

INTRODUCTION

In Ethiopia, measles continues to be the cause of a significant number of vaccine-preventable infant morbidity and mortality due to the low vaccination rate. However, understanding the geographical distribution of the measles-containing vaccine first dose (MCV1) and identifying associated factors is crucial to setting up appropriate interventions. This study aimed to explore the spatial distribution and associated factors of MCV1 coverage among children aged 12-23 months in Ethiopia using national representative data.

METHODS

A cross-sectional study design using a two-stage stratified sampling technique was used. The analysis was performed using STATA 14.2, ArcGIS 10.8, and SaTScan version 9.6 software. To find significant related factors with measles vaccination, researchers used multilevel logistic regression.

RESULTS

The prevalence of MCV1 in Ethiopia was 58.5%. A spatial variation of MCV1 coverage was observed across the study area. The most likely significant primary clusters with low MCV1 coverage were observed in Liben, Afder, Shebelle, Korahe, and Nogob zones of the Somali region; Bale and Guji zones of the Oromia region, and Gedeo and Sidama zones of the SNNPR. Rural areas, maternal primary education, secondary and above school education, Orthodox religion, Muslim religion, health facility delivery, and Afar region were significantly associated with MCV1 vaccination.

CONCLUSION

The overall MCV1 coverage in Ethiopia was low. Aside from the inadequate coverage, there was a geographical variation across the country. Low MCV1 coverage areas should be prioritized to improve vaccination efforts to control measles across the country.

Sexualized Substance Use among Female Sex Workers in Iran: Findings from a Nationwide Survey

Background: Female sex workers (FSWs) are at higher risk of HIV due to high-risk sexual and drug use related behaviors. This study characterized sexualized substance use among FSWs in Iran. Methods: In 2015, 1,337 FSWs were recruited from centers for vulnerable women and through outreach efforts in 13 major cities in Iran. Data were collected via face-to-face interviews from consenting FSWs on a range of socio-demographic and behavioral characteristics. The primary outcome of interest was sexualized substance use, defined as reporting alcohol or drug use before or during sex in the past month. Bivariable and multivariable modified Poisson regression models were used to assess the correlates of sexualized substance use. Adjusted prevalence ratio (aPR) and 95% confidence interval (CI) were reported. Results: The prevalence of sexualized substance use was 31.3% (95% CI: 28.7, 34.0). Inconsistent condom use during sex with clients in the past month (aPR = 1.31; 95% CI: 1.01, 1.71), regular (i.e., at least weekly in the past month) alcohol use (aPR = 2.87; 95% CI: 2.17, 3.80), regular opioid use (aPR = 2.09; 95% CI: 1.45, 3.02), regular stimulant use (aPR = 2.68; 95% CI: 2.12, 3.39), and self-reported HIV negative status (aPR= 1.88; 95% CI: 1.14, 3.10) were significantly and positively associated with sexualized substance use. Conclusions: Sexualized substance use was associated with riskier sexual behavior and self-reported HIV sero-negativity. Harm reduction messaging to FSWs needs to go beyond focusing on sexual health promotion and further highlight the risks associated with sexualized substance use.

Help-seeking and challenges faced by transwomen following exposure to gender-based violence; a qualitative study in the Greater Kampala Metropolitan Area, Uganda

BACKGROUND

The high prevalence of gender-based violence (GBV) among transwomen is a human rights and public health challenge. Nonetheless, there is limited evidence of sources of GBV support services and the challenges faced by transwomen while help-seeking, especially in transphobic settings like Uganda. This study explored the sources of GBV support services and the challenges faced by transwomen in the Greater Kampala Metropolitan Area during help-seeking.

METHODS

A qualitative study design involving 60 transwomen and 10 key informants was conducted. Respondents were recruited using snowball sampling. An in-depth interview (IDI), and a focus group discussion guide were used to collect data from 20 IDI respondents and six focus group discussants. Each focus group discussion averaged six participants. A key informant interview guide was used for key informant interviews. Data were transcribed verbatim and analysed following a thematic framework, informed by the socio-ecological model. Data were organised into themes and subthemes using NVivo 12.0.

RESULTS

The sources of support following exposure to GBV included key population-friendly healthcare facilities and civil society organisations (CSOs), and friends and family. Friends and family provided emotional support while key population-friendly healthcare facilities offered medical services including HIV post-exposure prophylaxis. Key population CSOs provided shelter, nutritional support, and legal advice to GBV victims. Lack of recognition of transgender identity; long distances to healthcare facilities; discrimination by healthcare providers and CSO staff, inappropriate questioning of the trans-gender identity by police officers and healthcare providers, and the lack of trans-competent healthcare providers and legal personnel hindered help-seeking following exposure to GBV.

CONCLUSION

The immediate sources of GBV support services included key population-friendly healthcare facilities and CSOs, police, and friends and family. However, a significant number of transwomen did not report incidences of GBV. Transwomen were discriminated against at some key population healthcare facilities and CSOs, and police, which hindered help-seeking following exposure to GBV. This study highlights the need to tackle internalized stigma and discrimination against transwomen at the existing sources of GBV support. There is also a need to train law enforcers and legal personnel on the right to access healthcare among transwomen in Uganda.

Serum LDH: a potential surrogate to chest radiograph in pediatric Covid-19 patients to reduce radiation exposure

Background

Chest radiographs are frequently used to evaluate pediatric patients with COVID-19 infection during the current pandemic. Despite the minimal radiation dose associated with chest radiography, children are far more sensitive to ionizing radiation's carcinogenic effects than adults. This study aimed to examine whether serum biochemical markers could be potentially used as a surrogate for imaging findings to reduce radiation exposure.

Methods

The retrospective posthoc analysis of 187 pediatric patients who underwent initial chest radiographs and serum biochemical parameters on the first day of emergency department admission. The cohort was separated into two groups according to whether or not the initial chest radiograph revealed evidence of pneumonia. Spearman's rank correlation was used to connect serum biochemical markers with observations on chest radiographs. The Student's t-test was employed for normally distributed data, and for non-normally distributed data, the Mann–Whitney U test was used. A simple binary logistic regression was used to determine the importance of LDH in predicting chest radiographs. The discriminating ability of LDH in predicting chest radiographs was determined using receiver operating characteristics (ROC) analysis. The cut-off value was determined using Youden's test. Interobserver agreement was quantified using the Cohen k coefficient.

Results

187 chest radiographs from 187 individual pediatric patients (95 boys and 92 girls; mean age ± SD, 10.1 ± 6.0 years; range, nine months–18 years) were evaluated. The first group has 103 patients who did not have pneumonia on chest radiographs, while the second group contains 84 patients who had evidence of pneumonia on chest radiographs. GGO, GGO with consolidation, consolidation, and peri-bronchial thickening were deemed radiographic evidence of pneumonia in group 2 patients. Individuals in group 2 with radiological indications of pneumonia had significantly higher LDH levels (p = 0.001) than patients in group 1. The Spearman's rank correlation coefficient between LDH and chest radiography score is 0.425, showing a significant link. With a p-value of < 0.001, the simple binary logistic regression analysis result validated the relevance of LDH in predicting chest radiography. An abnormal chest radiograph was related to LDH > 200.50 U/L (AUC = 0.75), according to the ROC method. Interobserver agreement between the two reviewers was almost perfect for chest radiography results in both groups (k = 0.96, p = 0.001).

Conclusion

This study results show that, compared to other biochemical indicators, LDH has an 80.6% sensitivity and a 62% specificity for predicting abnormal chest radiographs in a pediatric patient with confirmed COVID-19 infection. It also emphasizes that biochemical measures, rather than chest radiological imaging, can detect the pathogenic response to COVID-19 infection in the chest earlier. As a result, we hypothesized LDH levels might be potentially used instead of chest radiography in children with COVID-19, reducing radiation exposure.

Assessment of drugs administered in the Middle East as part of the COVID-19 management protocols

The pandemic spread of coronavirus (COVID-19) has been reported first at the end of 2019. It continues disturbing various human aspects with multiple pandemic waves showing more fatal novel variants. Now Egypt faces the sixth wave of the pandemic with controlled governmental measures. COVID-19 is an infectious respiratory disease-causing mild to moderate illness that can be progressed into life-threatening complications based on patients- and variant type-related factors. The symptoms vary from dry cough, fever to difficulty in breathing that required urgent hospitalization. Most countries have authorized their national protocols for managing manifested symptoms and thus lowering the rate of patients' hospitalization and boosting the healthcare systems. These protocols are still in use even with the development and approval of several vaccines. These protocols were instructed to aid home isolation, bed rest, dietary supplements, and additionally the administration of antipyretic, steroids, and antiviral drugs. The current review aimed to highlight the administered protocols in the Middle East, namely in Egypt and the Kingdom of Saudi Arabia demonstrating how these protocols have shown potential effectiveness in treating patients and saving many soles.

Assessment of contextual factors shaping delivery and uptake of isoniazid preventive therapy among people living with HIV in Dar es salaam, Tanzania

BACKGROUND

Tuberculosis has remained a leading cause of death among people living with HIV (PLHIV) globally. Isoniazid preventive therapy (IPT) is the recommended strategy by the World Health Organization to prevent TB disease and related deaths among PLHIV. However, delivery and uptake of IPT has remained suboptimal particularly in countries where HIV and TB are endemic such as Tanzania. This study sought to assess contextual factors that shape delivery and uptake of IPT in Dar es Salaam region, Tanzania.

METHODOLOGY

We employed a qualitative case study design comprising of in-depth interviews with people living with HIV (n = 17), as well as key informant interviews with clinicians (n = 7) and health administrators (n = 7). We used thematic data analysis approach and reporting of the results was guided by the Consolidated Framework for Implementation Research (CFIR).

RESULTS

Characteristics of IPT such as aligning the therapy to individual patient schedules and its relatively low cost facilitated its delivery and uptake. On the contrary, perceived adverse side effects negatively affected the delivery and uptake of IPT. Characteristics of individuals delivering the therapy including their knowledge, good attitudes, and commitment to meeting set targets facilitated the delivery and uptake of IPT. The process of IPT delivery comprised collective planning and collaboration among various facilities which facilitated its delivery and uptake. Organisational characteristics including communication among units and supportive leadership facilitated the delivery and uptake of IPT. External system factors including HIV stigma, negative cultural and religious values, limited funding as well as shortage of skilled healthcare workers presented as barriers to the delivery and uptake of IPT.

CONCLUSION

The factors influencing the delivery and uptake of IPT among people living with HIV are multifaceted and exist at different levels of the health system. Therefore, it is imperative that IPT program implementers and policy makers adopt multilevel approaches that address the identified barriers and leverage the facilitators in delivery and uptake of IPT at both community and health system levels.

HIV testing and associated factors among men (15-64 years) in Eastern Africa: a multilevel analysis using the recent demographic and health survey

BACKGROUND

Despite significant efforts made to prevent human immunodeficiency virus (HIV) transmission, its testing coverage among men is still low and remains a major concern in low-income countries, particularly in East Africa. Therefore, this study aimed to determine the prevalence and associated factors of HIV testing among men in Eastern Africa.

METHODS

We analyzed secondary data using Demographic and Health Surveys (DHS) drawn from Eastern African countries. Besides, we merged DHS data from eleven Eastern African countries. In this study, we included secondary data from 113, 270 men aged 15-64 years. The outcome variable of this study was "ever been tested for HIV". Bivariable and multivariable multi-level logistic regression analyses were employed. In the bivariable analysis, variables having a P-value of less than 0.2 were selected for multivariable analysis. Lastly, variables with a P-value of < 0.05 in the multivariable analysis were declared as a significant factor associated with HIV testing and the adjusted odds ratio (AOR) with the 95% confidence interval (CI) were computed to determine the strength and direction of the association.

RESULTS

The overall prevalence of HIV testing among men in eastern Africa was 60.5% (95% CI: 60.2, 60.7%). In the multivariable multilevel analysis; participant's older age, being married, increased poverty, HIV knowledge, risky sexual behavior, and being covered by health insurance were positively associated with HIV testing coverage among men. However, men with higher community illiteracy levels, residing in rural settings, age at first sex ≥20 years, and higher stigmatized attitudes towards HIV/AIDS had lower odds of being tested for HIV.

CONCLUSION

The overall prevalence of HIV testing among men in eastern Africa was relatively higher than the previous studies. The study revealed that age, marital status, residence, age at first sex, community poverty level, community illiteracy level, HIV knowledge, HIV stigma indicator, risky sexual behavior, and health insurance were significantly associated with HIV testing coverage among men. Therefore, all the concerned stakeholders need to develop an integrated strategic plan through providing special attention to the factors that affect the uptake of HIV testing to raise awareness about the importance of HIV testing and to prevent HIV/AIDS transmission.

Prediction of Ross River virus incidence in Queensland, Australia: building and comparing models

Transmission of Ross River virus (RRV) is influenced by climatic, environmental, and socio-economic factors. Accurate and robust predictions based on these factors are necessary for disease prevention and control. However, the complicated transmission cycle and the characteristics of RRV notification data present challenges. Studies to compare model performance are lacking. In this study, we used RRV notification data and exposure data from 2001 to 2020 in Queensland, Australia, and compared ten models (including generalised linear models, zero-inflated models, and generalised additive models) to predict RRV incidence in different regions of Queensland. We aimed to compare model performance and to evaluate the effect of statistical over-dispersion and zero-inflation of RRV surveillance data, and non-linearity of predictors on model fit. A variable selection strategy for screening important predictors was developed and was found to be efficient and able to generate consistent and reasonable numbers of predictors across regions and in all training sets. Negative binomial models generally exhibited better model fit than Poisson models, suggesting that over-dispersion in the data is the primary factor driving model fit compared to non-linearity of predictors and excess zeros. All models predicted the peak periods well but were unable to fit and predict the magnitude of peaks, especially when there were high numbers of cases. Adding new variables including historical RRV cases and mosquito abundance may improve model performance. The standard negative binomial generalised linear model is stable, simple, and effective in prediction, and is thus considered the best choice among all models.

HIV status disclosure and sexual activity among pregnant women in Ghana

Human Human immunodeficiency virus (HIV) status disclosure to sexual partners is associated with prevention, care, treatment, and support for pregnant women with HIV. We aimed to assess HIV status disclosure and sexual activity among pregnant women with HIV. We conducted a cross-sectional hospital-based survey using quantitative methods. Data were collected from 118 pregnant women with HIV enrolled in the prevention of mother-to-child transmission (PMTCT) program from January to November 2019. Sixty-seven percent (67%) of these pregnant women did not know they had HIV until they were tested in the routine antenatal HIV testing program. HIV status nondisclosure rate was 62.7%, and the most common reason for nondisclosure was fear of loss of financial support (41.9%). Higher parity was associated with lower odds of disclosing HIV status (aOR = 0.36; p < 0.01). Sexual activity with partners and condom use were associated with HIV disclosure (ps < 0.01). Pregnant women who disclosed their HIV status to their partners were sexually active with them (37.3%), and all those who did not but were sexually active with their partners did not use condoms (36.2%) during the pregnancy. Our findings emphasize the need for interventions that encourage HIV status disclosure and affirm the importance of routine HIV testing for pregnant women.

The arrival of highly pathogenic avian influenza viruses H5N8 in Iran through two windows, 2016

The highly pathogenic avian influenza (HPAI) H5N1 virus has received considerable attention during the past 2 decades due to its zoonotic and mutative features. This Virus is of special importance due to to the possibility of causing infection in human populations. According to it's geographical location, Iran hosts a large number of aquatic migratory birds every year, and since these birds can be considered as the host of the H5 HPAI, the country is significantly at risk of this virus. the In this study, the molecular characteristics of hemagglutinin (HA) and neuraminidase (NA) genes of the H5N8 strain were identified in Malard county of Tehran province and Meighan wetland of Arak city, Markazi province were investigated. Based on the analysis of the amino acid sequence of the HA genes, the cleavage site of the gene includes the PLREKRRKR/GLF polybasic amino acid motif, which is a characteristic of highly pathogenic influenza viruses. The HA gene of two viruses had T156A, S123P, S133A mutations associated with the increased mammalian sialic acid-binding, and the NA gene of two viruses had H253Y mutations associated with the resistance to antiviral drugs. Phylogenetic analysis of the HA genes indicated the classification of these viruses in the 2.3.4.4 b subclade. Although the A/Goose/Iran/180/2016 virus was also an H5N8 2.3.4.4 b virus, its cluster was separated from the A/Chicken/Iran/162/2016 virus. This means that the entry of these viruses in to the country happened through more than one window. Furthermore, it seems that the introduction of these H5N8 HPAI strains in Iran probably occurred through the West Asia-East African flyway by wild migratory aquatic birds.

They call us goor-jigeen: a qualitative exploration of the experiences of Senegalese Muslim men who have sex with men living with HIV

Men who have sex with men living with HIV in majority Muslim communities face discrimination based on multiple forms of stigma at socio-cultural and legislative levels. This study aimed to explore qualitatively the experiences of men who have sex with men living with HIV in Dakar, Senegal. In-depth individual interviews were conducted with 30 Senegalese men aged 18 to 55 years, who self-reported as same-sex practising, Muslim, and receiving HIV treatment at health centres in Dakar. Interview data were analysed using an ethnographic phenomenological approach to explore their life experiences. Primary themes included: the self-discovery process; the social, religious and health ramifications of being same-sex practising; and stigma. Within the theme of stigma issues described included shame, blame (of self and others), and violence resulting from being a man who has sex with other men and/or being HIV seropositive. Those with undetectable viral load reported how HIV related stigma and burden diminished as their health improved. Disclosure of being men who have sex with men and/or HIV status, whether voluntary or not, affected experiences of violence and/or isolation. Addressing stigma at healthcare institutions and improving access to HIV treatment can help mitigate the burden of stigma affecting such men. Interventions to address their physical and psychosocial wellbeing require the engagement of multiple stakeholders, including religious and political leaders.

Effect of sputum quality and role of Xpert® MTB/ RIF assay for detection of smear-negative pulmonary tuberculosis in same-day diagnosis strategy in Addis Ababa, Ethiopia

Background

There is limited information on the performance of the Xpert® MTB/RIF test for diagnosis of smear-negative pulmonary tuberculosis (SNPT) and rifampicin resistance (RR) in the same-day diagnosis approach. The effects of sputum quality and other factors affecting the Xpert performance are also under-investigated.

Objective

This study aimed to determine the performance of the Xpert® MTB/RIF test for detection of SNPT and RR in the same-day diagnosis strategy and the effect of sputum quality and other factors on its performance.

Methods

A cross-sectional study was conducted from August 2017 to January 2018 across 16 health facilities in Addis Ababa, Ethiopia. Two spot sputum samples were collected from 418 presumptive SNPT patients, tested with Xpert® MTB/RIF, then compared to tuberculosis culture. Additionally, culture isolates were tested for RR by BACTEC MGIT™ 960 drug susceptibility testing (DST) and MTBDRplus version 2.

Results

The Xpert® MTB/RIF test detected 24 (5.7%) SNPT cases, with a sensitivity of 92.3% (75.9% - 97.9%) and specificity of 99.2% (97.8% - 99.7%) compared with tuberculosis culture. Xpert® MTB/RIF also detected three (11.58%) RR strains with 100.0% concordance with BACTEC MGIT™ 960 DST and MTBDRplus results. Three blood-stained SNPT samples were positive by Xpert (30.0%), which was 6.9 times higher compared to salivary sputum (odds ratio: 6.9, 95% confidence interval: 1.36-34.96, p = 0.020).

Conclusion

The performance of the Xpert® MTB/RIF to detect SNPT and RR in same-day diagnosis is high. However, SNPT positivity varies among sputum qualities, and good sample collection is necessary for better test performance.

Infective endocarditis by HACEK: a review

Infective endocarditis (IE) is a severe disease that is still associated with high mortality despite recent advances in diagnosis and treatment. HACEK organisms (Haemophilus spp., Aggregatibacter actinomycetemcomitans, Cardiobacterium hominis, Eikenella corrodens, and Kingella kingae) are gram-negative bacteria that are part of the normal flora of the mouth and upper respiratory tract in humans. These organisms cause a wide range of infections, of which IE is one of the most notable. In order to control and prevent endocarditis caused by HACEK, measures such as oral hygiene and the use of prophylactic drugs should be used for people at risk, including people with underlying heart disease and people with artificial valves. This review is a summary of the main aspects of IE focusing on HACEK organisms.

Laboratory Findings in Different Disease Status of COVID-19 Admitted Patients at Dilla University Referral Hospital Treatment Center, South Ethiopia

Background

Millions were infected and many were dying because of the coronavirus disease 2019, since its emergence. The patients experience asymptomatic, mild, moderate, severe and critical disease with varying signs and symptoms. Decreased lymphocytes and abnormal liver and renal function tests are common among COVID-19 patients. Severe and critical cases show higher number of white blood cells, and neutrophils. However, studies showed different laboratory findings in different disease status. Therefore, this study investigated laboratory findings of COVID-19 admitted patients at Dilla University Referral Hospital treatment center, South Ethiopia.

Methods

A retrospective study design was conducted on 220 patients confirmed by real time polymerase chain reaction, and admitted to Dilla University Referral Hospital treatment center from September 2020 to July 2021. Data were collected from the patients’ record, and analyzed by GraphPad Prism version 8.0.1.244 software. Descriptive statistics were used to analyze the frequency while independent t-test was used to compare means of each parameter for each disease status.

Results

Of the 220 study cases, 120 (54.5%) were severe, 89 (40.5%) were moderate and 11 (5.0%) were mild. One hundred forty (71.1%) of the 197 laboratory tested cases, 87 (77.7%) of severe, and 49 (64.5%) of the moderate cases had neutrophils above normal range. However, 134 (68.0%) of them, 82 (73.2%) of severe and 49 (64.5%) of moderate cases showed decreased lymphocyte level. Most of the cases showed an increased level of aspartate transaminase, alanine transaminase, alkaline phosphatase, total bilirubin, and total calcium. There was statistically significant mean neutrophils (p=0.04), number of white blood cells (p= 0.02), and creatinine level (p=0.00) difference between severe and mild cases.

Conclusion

Most of the severe COVID-19 patients showed increased neutrophils, liver function tests; and decreased lymphocytes; suggesting higher inflammation and lymphopenia. Therefore, patients with severe and critical disease status require close follow-up.

Building sustainable and scalable peer-based programming: promising approaches from TESFA in Ethiopia

Background

Girls in Ethiopia’s Amhara region experience high rates of child marriage and are less able to negotiate sex or use family planning. Seeking to improve their lives, CARE’s TESFA programme delivered reproductive health and financial savings curricula to married girls via reflective dialogues in peer-based solidarity groups. From 2010 to 2013, 5,000 adolescent girls participated via three intervention arms: sexual and reproductive health, economic empowerment, and a combination of both. At end-line, participants reported improvements across health and empowerment outcomes. Four years post-TESFA, 88% of groups reported meeting without continued assistance from CARE. Some original participants had created new groups based on the TESFA model, and some girls not recruited for TESFA spontaneously replicated it to create their own groups. However, questions remained about what had contributed to this organic sustainment and scale-up of groups.

Methods

This 2018 study investigated factors affecting sustainability and scale-up of peer solidarity groups through a systematic mapping of TESFA groups across five woredas (districts) and interviews with key stakeholders. Data were collected from 39 focus groups with active and dissolved Girl Groups, Social Analysis and Action groups, and girls’ husbands and from 29 in-depth interviews with group facilitators and community health workers across three districts. Data were coded and analyzed per grounded theory principles.

Results

Changes in reproductive health knowledge and specific behaviours, such as contraceptive use and institutional delivery, were maintained 5 years after the intervention ended. Group connectedness, spousal support, integration of holistic community platforms, and opportunities for financial independence were found to be important for group sustainability. Observed changes in TESFA girls’ confidence to negotiate and assert their rights, hopes of improved mobility, and the promise of economic opportunity commonly inspired spontaneous replication of groups. Recommendations for future peer-based programmes include creating environments of solidarity and holistically engaging intervention communities.

Conclusion

By increasing knowledge of and access to reproductive health services, TESFA mitigates some of the harmful effects of child marriage. The maintenance and organic replication of groups suggest that TESFA provides a successful, scalable and sustainable tested model for reproductive health program delivery through peer-based solidarity groups.

In Ethiopia, married girls are a particularly vulnerable adolescent population because of the many health risks associated with early marriage. Peer-based approaches are a common strategy to improve sexual and reproductive health knowledge and behaviours for marginalized groups. Critiques of these approaches are that they lack sustainability without ongoing investment and have no lasting impact on health behaviours. CARE’s TESFA programme, a peer-based approach with married adolescent girls in South Gondar, was found to be effective in creating long-term behavior change related to uptake of family planning and rates of institutional delivery. Some 88% of groups who received the TESFA curriculum were still meeting 4 years after the programme had concluded. Some participants even created groups of their own, scaling TESFA beyond the original audience, suggesting a potential approach to wider scale-up. To explore lessons learned around scale and sustainability, this study interviewed TESFA participants and stakeholders.

Improvements in behaviours related to contraceptive use, institutional delivery, and girls’ agency in reproductive decision-making were sustained over time regardless of group status. Factors that affected the sustainability and scale-up of groups included solidarity among group members, support from husbands and community members, ongoing savings and loan structures, flexibility of group processes, and availability of relevant curriculum topics. Through an analysis of these findings, this paper discusses recommendations for sustainable and scalable peer-based programme design via existing Ethiopian community structures. Using TESFA principles as a model, practitioners could design and implement scalable and sustainable peer-based programming for adolescents sexual and reproductive health.

Evaluating the efficacy of stool sample on Xpert MTB/RIF Ultra and its comparison with other sample types by meta-analysis for TB diagnostics

Precise and timely detection of tuberculosis (TB) is crucial to reduce transmission. This study aims to assess the accuracy of Xpert MTB/RIF Ultra on stool samples and systematically review the performance of Xpert MTB/RIF Ultra with different sample types by meta-analysis. Stool samples of smear-negative pulmonary TB (PTB), cervical lymph node TB, and abdominal TB patients were tested on the Xpert MTB/RIF Ultra system. Meta-analysis was performed on a set of 44 studies. Data were grouped by sample type, and the pooled sensitivity and specificity of Xpert MTB/RIF Ultra were calculated. The sensitivity of Xpert MTB/RIF Ultra with stool samples was 100% for smear-negative PTB, 27.27% for cervical lymph node TB, and 50% for abdominal TB patients, with 100% specificity for all included TB groups. The summary estimate for all PTB samples showed 84.2% sensitivity and 94.5% specificity, and EPTB samples showed 88.6% sensitivity and 96.4% specificity. Among all sample types included in our meta-analysis, urine showed the best performance for EPTB diagnosis. This pilot study supports the use of stool as an alternative non-invasive sample on Xpert MTB/RIF Ultra for rapid testing, suitable for both PTB and EPTB diagnosis.
