Abdul-Samed FG, Abubakari A, Yussif BG, Aninanya GA. Determinants of adherence to antiretroviral therapy among people living with HIV receiving care in health facilities in Tamale Metropolis, Ghana. BMC Infect Dis 2024; 24:1379. [PMID: 39627694 PMCID: PMC11616107 DOI: 10.1186/s12879-024-10240-3] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/02/2024] [Accepted: 11/18/2024] [Indexed: 12/06/2024] Open
Abstract
BACKGROUND Strictly following antiretroviral therapy (ART) is essential in managing HIV and AIDS and attaining viral suppression. However, adherence to ART remains a complex challenge among persons living with HIV (PLHIV) and it is influenced by various individual and socio-cultural factors. Also, there is limited data as far as the studies on determinants of ART adherence in the Tamale Metropolis is concerned. This highlights a critical knowledge gap that needs to be addressed to improve adherence rates. This study therefore aims to examine the determinants of ART adherence among PLHIV in the Tamale Metropolis, Ghana. METHODS A facility-based cross-sectional study design was conducted from November 2023 to February 2024 to recruit 418 PLHIV using consecutive sampling from three healthcare facilities located in the Tamale Metropolis. Data were collected on demographic characteristics, adherence behaviours and socio-cultural beliefs. Every element impacting adherence to ART underwent assessment using a 4-point Likert scale, with data entry and coding executed using Microsoft Excel, followed by statistical analyses using SPSS version 21. Fisher's exact test, Chi-square test and multiple logistic regression analyses were utilized to ascertain autonomous indicators of ART adherence while accounting for the impact of other factors. Determinants of ART were considered statistically significant at a p-value of less than 0.05 with a 95% confidence interval. RESULTS A total of 418 PLHIV were studied, yielding a 100% response rate and an ART adherence rate of 93%, with a 95% confidence interval ranging from 90.6% to 95.4%. Clients who were educated (AOR = 6.80, 95% CI: 1.57-29.42, p = 0.010), retentive (AOR = 10.73, 95% CI: 4.24-27.15, p < 0.001), had aversion for alternative treatment modalities (AOR = 8.04, 95% CI: 2.90-22.29, p < 0.001) and involved with peer support groups (AOR = 3.73, 95% CI: 1.02-13.56, p < 0.05) exhibited markedly higher rates of adherence to ART, as relative to those who did the opposite. CONCLUSION The study identified a sub-optimal adherence rate of 93% among PLHIV with key determinants of ART adherence. Among individual factors, educational attainment and forgetfulness played a significant role in influencing adherence levels. In terms of sociocultural factors, inclinations toward alternative therapies, such as traditional or herbal remedies, and active engagement in peer support networks were found to impact adherence. The Ghana AIDS Commission and its partners should implement targeted educational programs, interventions such as reminder systems (e.g., mobile phone alerts, pill organizers) should be developed and promoted, develop culturally sensitive outreach programs that respect traditional beliefs while promoting the benefits of ART and strengthen peer support networks.

Parasite Epidemiol Control 2024; 27:e00379. [PMID: 39314209 PMCID: PMC11417321 DOI: 10.1016/j.parepi.2024.e00379] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/28/2024] [Revised: 07/19/2024] [Accepted: 09/03/2024] [Indexed: 09/25/2024] Open
Abstract
Background Little attention has been paid to determining the prevalence and associated factors of soil-transmitted helminth (STH) infections in some developing countries. This study was, therefore, carried out to determine the prevalence and associated factors of STH infections among schoolchildren attending three primary schools in Mekane Eyesus town, northwestern Ethiopia. Methods A school-based cross-sectional study was conducted from March to June 2023 in Mekane Eyesus town. Stool samples were collected from 401 children from three primary schools in the town. Wet-mount and formol ether concentration techniques were used to diagnose stool samples, and a structured questionnaire was used to collect data on socio-demographic characteristics and risk factors for STH infections. Results The overall prevalence of STH infection in this study was 18.2 % (73/401). The most common helminth species detected was Ascaris lumbricoides (A. lumbricoides) (7.5 % (30/401)). Not trimming fingernails regularly (adjusted odds ratio (AOR) = 3.75, 95 % CI = 1.87-7.50), having illiterate fathers (AOR = 2.29, 95 % CI = 1.18-4.44), and being aged 15-17 years (AOR = 2.37, 95 % CI = 1.06-5.30) were associated with increased odds of STH infection. Children who wash their hands after defecation (AOR = 0.43, 95 % CI = 0.21-0.88) and those whose mothers were housewives (AOR = 0.22, 95 % CI = 0.08-0.58) had lower odds of STH infection. Conclusion This study found a high prevalence of STH infection among schoolchildren in Mekane Eyesus town. Thus, STH infection preventive measures, including deworming of schoolchildren, should be implemented in the study area. Moreover, giving health-related knowledge about STH infection prevention strategies, such as regular fingernail trimming and hand washing after defecating, is vital for reducing the prevalence of STH infections in the study area.

Abstract
Extra-intestinal pathogenic Escherichia coli (ExPEC) is a virulent pathogen found in humans that causes the majority of urinary tract infections, and other infections such as meningitis and sepsis. ExPEC can enter the urinary tract through two modes: ascending from the bladder or descending from the kidneys. Human anatomical structures generally prevent the transmission of pathogens between the extra-intestinal area, kidneys, bladder, and urinary tract. However, adhesins, a virulence protein of ExPEC, promote the initial bacterial attachment and invasion of host cells. In addition to adhesion proteins, ExPEC contains iron acquisition systems and toxins to evade the host immune system, acquire essential nutrients, and gain antibiotic resistance. The presence of antibiotic-resistant genes makes treating ExPEC in urinary tract infections (UTIs) more complicated. Therefore, screening for the presence of ExPEC among other uropathogens in UTI patients is essential, as it can potentially aid in the effective treatment and mitigation of ExPEC pathogens. Several diagnostic techniques are available for detecting ExPEC, including urine culture, polymerase chain reaction, serological testing, loop-mediated isothermal amplification, and biochemical tests. This review addresses strain-specific diagnostic techniques for screening ExPEC in UTI patients.

Heliyon 2024; 10:e35319. [PMID: 39161839 PMCID: PMC11332886 DOI: 10.1016/j.heliyon.2024.e35319] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/28/2023] [Revised: 07/25/2024] [Accepted: 07/26/2024] [Indexed: 08/21/2024] Open
Abstract
Introduction Adherence to Option B+ antiretroviral medication (ART) is essential for the successful implementation of the Prevention of Mother-to-Child Transmission (PMTCT) program. However, poor adherence to Option B + PMTCT drugs among women results in increased viral load and mother-to-child transmission and reduces immunological and clinical outcomes. Objective The objective of the study was to assess the level of Option B plus drug adherence for preventing mother-to-child transmission of HIV and associated factors among HIV positive women in selected government health facilities of Awi zone, Amhara region, Northwest Ethiopia,2020. Methods This institutional-based cross-sectional study was conducted from March 1 to April 30 among 358 HIV-positive women (pregnant and lactating mothers). A multistage sampling procedure was used to select the study participants. Data were collected using a structured questionnaire through interviews. The collected data were entered into EPI Data 3.1 statistical software for data management and analyzed using SPSS version 25 statistical package. The associations between variables were analyzed using bivariate and multivariable logistic regression models. A p-value ≤0.05 at the 95 % confidence interval was considered statistically significant. Results Out of the 358 participants, adherence to Option B + PMTCT was 83.24 %. The study revealed that counselling [AOR = 4.4, 95 % CI: 1.60-12.29], partner support involvement [AOR = 3.0, 95 % CI: 1.17-7.92], and time taken to reach from home to the facility [AOR = 3.1, 95 % CI: 1.51-6.52] were significantly associated with the level of adherence to Option B + PMTCT. Conclusion This study showed that the level of Option B + PMTCT drug adherence was lower than the nationally recommended adherence level. Good counselling, partner support, and reduced travel time from home to the facility were associated with adherence to Option B + PMTCT drugs. Therefore, counselling is crucial for increasing adherence to Option B + PMTCT drugs. Accessible health facilities reduce travel burdens, encourage regular clinic visits, and enhance adherence to PMTCT drugs. Partners can provide reminders, attend appointments, offer emotional support, and explore alternatives such as mobile clinics or medication delivery services.

Girma A, Genet A. Prevalence and factors associated with intestinal parasitic infections among preschool-aged children in Ethiopia: A systematic review and meta-analysis. Parasite Epidemiol Control 2024; 26:e00368. [PMID: 39076827 PMCID: PMC11284566 DOI: 10.1016/j.parepi.2024.e00368] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/09/2023] [Revised: 05/28/2024] [Accepted: 07/05/2024] [Indexed: 07/31/2024] Open
Abstract
Intestinal parasitic infections (IPIs) pose a serious public health threat across the globe, particularly in children residing in poor and most deprived communities like Ethiopia. Many published articles were available separately, and a detailed nationwide review was essential to combine all the results to draw a conclusion and avoid any informational conflicts, ambiguities, or misunderstandings. Therefore, this systematic review and meta-analysis aimed to provide pooled estimates for the individually available data on IPIs and its determinant factors among preschool-aged children (PSAC) in Ethiopia. Published and unpublished articles from various electronic databases were accessed using MeSH terms and keywords. I 2 and sensitivity analysis tests were used to assess potential sources of heterogeneity across studies. Funnel plot, Begg's, and Egger's regression tests were used to check publication bias. A random-effects model with a 95% confidence interval (CI) was used to calculate the pooled estimate of IPI. In this meta-analysis, a total of 14,994 PSAC were included in the 32 eligible studies. The pooled national prevalence of IPIs among PSAC was 32.52% (95% CI: 26.24, 38.80). Of these, single and mixed infections contribute 31.08% and 1.44%, respectively. According to the subgroup analysis, the highest prevalence was observed in simple random studies (39.61%; 95% CI: 29.19, 50.03), the Tigray region (58.00%; 95% CI: 54.10, 61.90), studies conducted in >384 (39.47%; 95% CI: 27.73, 51.20) sample sizes, cross-sectional studies (32.76%), community-based studies (42.33%; 95% CI: 31.93, 52.74), and from 2005 to 2016 (34.53%; 95% CI: 20.13, 48.92) study periods. Intestinal parasites were significantly associated with eating raw fruits and vegetables (aOR = 3.21; 95%CI: 1.11-5.31). The high prevalence of STHs observed in this systematic review and meta-analysis underscores the need for appropriate control and prevention strategies suitable for PSAC in Ethiopia.

Abstract
Background Enhancing outcomes post-hospitalisation requires an understanding of predictive factors for adverse events. This study aimed to estimate post-discharge mortality rates among patients with severe acute respiratory infection (SARI) in Bangladesh, identify associated factors, and document reported causes of death. Methods From January 2012 to December 2019, we conducted follow-up calls to patients or their families 30 days after discharge to assess the status of patients with SARI. Proportions of deaths within 30 days of discharge were estimated, and a comparative analysis of demographics, clinical characteristics, and influenza illness between decedents and survivors was performed using multivariable Cox regression models. Findings Among 23,360 patients with SARI (median age: 20 years, IQR: 1.5-48, 65% male), 351 (1.5%) died during hospitalisation. Of 23,009 patients alive at discharge, 20,044 (87%) were followed, with 633 (3.2%) deaths within 30 days of discharge. In children (<18 years), difficulty breathing (adjusted hazard ratio [aHR] 1.8; 95% CI 1.1-3.0), longer hospital stay (aHR 1.1; 95% CI 1.1-1.1), and heart diseases (aHR 8.5; 95% CI 3.2-23.1) were associated with higher post-discharge death risk. Among adults (≥18 years), difficulty breathing (aHR 2.3; 95% CI 1.7-3.0), chronic obstructive pulmonary disease (aHR 1.7; 95% CI 1.4-2.2), and intensive care unit admission (aHR 5.2; 95% CI 1.9-14.0) were linked to elevated post-discharge death risk. Influenza virus was detected in 13% (46/351) of in-hospital SARI deaths and 10% (65/633) of post-discharge SARI deaths. Interpretation Nearly one in twenty patients with SARI died during hospitalisation or within 1 month of discharge, with two-thirds of deaths occurring post-discharge. Seasonal influenza vaccination is recommended to mitigate influenza-associated mortality. To enhance post-discharge outcomes, hospitals should consider developing safe-discharge algorithms, reinforcing post-discharge care plans, and establishing outpatient monitoring for recently discharged patients.

Level of antiretroviral therapy adherence and associated factors during COVID-19 pandemic era in public hospitals of Jigjiga City eastern Ethiopia: a cross-sectional study. Front Public Health 2024; 12:1363903. [PMID: 38855457 PMCID: PMC11156993 DOI: 10.3389/fpubh.2024.1363903] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/07/2024] [Accepted: 05/07/2024] [Indexed: 06/11/2024] Open
Abstract
Background Coronavirus-19 disease is more severe in patients on antiretroviral therapy (ART). Low-income countries, such as those in Sub-Saharan Africa, are particularly vulnerable to the virus' spread. However, there is little information on antiretroviral therapy (ART) use in Ethiopia during the pandemic, particularly in the study area. Therefore, this study aimed to assess the level of antiretroviral treatment adherence and associated factors during the COVID-19 pandemic era in public hospitals in Jigjiga City, Somalia, and Eastern Ethiopia. Methods An institution-based cross-sectional study was conducted among 382 randomly selected HIV patients on antiretroviral therapy (ART) follow-up in public hospitals in Jigjiga City from March 1-30, 2022. The data was collected through face-to-face interviews and a review of the patient's record. To explore the relationship between variables, both bivariate and multivariable logistic regression analyses were performed. The adjusted odds ratio (AOR) was utilized, along with a 95% confidence interval, to assess the strength and direction of the association. Statistical significance was considered at p < 0.05. Results The antiretroviral therapy (ART) adherence rate of HIV patients was 76.9% (95% CI, 71.9-82). Disclosing HIV status to sexual partners [AOR = 2.3, (95% CI (1.22-4.19)], having communication with health care providers' [AOR = 3.2, (95% CI (1.57-6.53)], having no history of current substance use [AOR = 2.6, (95% CI (1.45-4.63)], and patients who did not fear COVID-19 infection [AOR = 5.8 (95% CI (11-10.98)] were significantly associated with antiretroviral therapy (ART) adherence. Conclusion In this study, the level of antiretroviral therapy (ART) adherence was poor in comparison to the expected level. Patients' adherence status was favorably related to disclosing their status to families and having contact with their healthcare providers, whereas worrying about COVID-19 pandemic infection and current substance use was adversely associated.

Abstract
BACKGROUND Soil-transmitted helminthiasis (STH) refers to a set of parasitic illnesses caused by nematode worms and spread to people through faeces-contaminated soil. It is highly prevalent in low- and middle-income countries due to a lack of environmental sanitation and personal hygiene. Pregnant women are among the risk groups for infection by soil-transmitted helminths. Former studies of the disease burden among pregnant women in Ethiopia didn't indicate the intensity of parasitic infection. The aim of this study was to assess the prevalence and associated factors of soil-transmitted helminths among pregnant women. METHODS An institution-based cross-sectional study was conducted among 416 randomly selected pregnant women. The data were collected using a structured interview-administered questionnaire and a laboratory test. The Kato-Katz technique was used to diagnose soil-transmitted helminthiasis and determine the intensity of the infection. The collected data were entered into Epi-Data version 4.6 and exported to SPSS version 25 for analysis. Multivariate logistic regression analysis was used to identify independent predictors of soil-transmitted helminths at a p-value < 0.05. RESULTS The overall prevalence of soil-transmitted helminths among pregnant women was 30%. (95%, CI: 26-34%). Living in a rural area (AOR = 3.35; 95% CI = 1.83-6.13), drinking from an unprotected water source (AOR = 2.52; 95% CI = 1.45-4.37), not washing one's hand after the toilet (AOR = 2.75; 95% CI = 1.55-4.88), lacking health information (AOR = 1.70; 95% CI = 1.01-2.85), working as a daily labourer (AOR = 2.88; 95% CI = 1.01-8.20), and walking barefoot (AOR = 4.00; 95% CI = 2.29-7.00) were significantly associated with the presence of soil-transmitted helminths among pregnant women. CONCLUSION The prevalence of STH was significantly moderate in the study area, where pregnant women were mostly affected by ascariasis and hookworms. Living in a rural area, being a daily labourer, walking barefoot, not washing hands after the toilet, drinking from an unprotected water source, and lacking health information were the determining factors. Interventions including health education, the expansion of pure drinking water sources, the promotion of personal hygiene, and the wearing of shoes are recommended to reduce the burden of soil-transmitted helminths in the study area.

Abstract
BACKGROUND Mycobacterium leprae causes leprosy that is highly stigmatized and chronic infectious skin disease. Only some diagnostic tools are being used for the identification M. leprae in clinical samples, such as bacillary detection, and histopathological tests. These methods are invasive and often have low sensitivity. Currently, the PCR technique has been used as an effective tool fordetecting M. leprae DNA across different clinical samples. The current study aims to detect M. leprae DNA in urine samples of untreated and treated leprosy patients using the Rlep gene (129 bp) and compared the detection among Ridley-Jopling Classification. METHODS Clinical samples (Blood, Urine, and Slit Skin Smears (SSS)) were collected from leprosy and Non-leprosy patients. DNA extraction was performed using standard laboratory protocol and Conventional PCR was carried out for all samples using Rlep gene target and the amplicons of urine samples were sequenced by Sanger sequencing to confirm the Rlep gene target. RESULTS The M. leprae DNA was successfully detected in all clinical samples across all types of leprosy among all the study groups using RLEP-PCR. Rlep gene target was able to detect the presence of M. leprae DNA in 79.17% of urine, 58.33% of blood, and 50% of SSS samples of untreated Smear-Negative leprosy patients. The statistical significant difference (p = 0.004) was observed between BI Negative (Slit Skin Smear test) and RLEP PCR positivity in urine samples of untreated leprosy group. CONCLUSION The PCR positivity using Rlep gene target (129 bp) was highest in all clinical samples among the study groups, across all types of leprosy. Untreated tuberculoid and PNL leprosy patients showed the highest PCR positivity in urine samples, indicating its potential as a non-invasive diagnostic tool for leprosy and even for contact screening.

Aemiro A, Menkir S, Girma A. Prevalence of Soil-Transmitted Helminth Infections and Associated Risk Factors Among School Children in Dembecha Town, Ethiopia. ENVIRONMENTAL HEALTH INSIGHTS 2024; 18:11786302241245851. [PMID: 38628466 PMCID: PMC11020722 DOI: 10.1177/11786302241245851] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 01/29/2024] [Accepted: 03/20/2024] [Indexed: 04/19/2024]
Abstract
Soil-transmitted helminth (STH) infections are among the most common infections that affect the poorest and most deprived communities. In most developing countries, children aged 5 to 15 years are at risk for chronic helminth infection and associated morbidity. This study aimed to determine the prevalence of STH infections and associated risk factors among three government elementary schools in Dembecha town, Ethiopia. We conducted a school-based cross-sectional study involving 316 participants between November 2019 and March 2020. A systematic random sampling method was used to select study participants from the study schools. Data related to the sociodemographic characteristics of the study participants and risk factors for STH infections were collected using a pretested questionnaire survey. Parasitological examinations of stool samples were performed using the formal-ether concentration method. Study participants aged 5 to 15 years were enrolled in this study. The overall prevalence of STH infection was 21.5% (68/316). Ascaris lumbricoides ranked highest, with a prevalence of 11.4%, followed by hookworms 7.3%, Trichuris trichiura 1.9%, and Strongloides stercoralis 0.9%. Age groups of 10-15 years (AOR =3.109; 95% CI: 1.033, 9.350), residence in Kebele 2 (AOR =2.990; 95% CI: 1.082, 8.264), illiterate mothers (AOR =4.689; 95% CI: 1.410, 15.59), and a family size of 4-6 (AOR =3.286; 95% CI: 1.299, 8.313) were significantly associated with STH infections. The prevalence of STH infections remains an important health issue for study participants. Therefore, school deworming programs twice a year are crucially needed until the prevalence falls below the level of public health importance.

Perception of Healthcare Professionals towards Electronic-Prescribing at University of Gondar Comprehensive Specialized Hospital, Northwest Ethiopia: A Cross-Sectional Study. BIOMED RESEARCH INTERNATIONAL 2024; 2024:6553470. [PMID: 38633242 PMCID: PMC11022515 DOI: 10.1155/2024/6553470] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 06/05/2023] [Revised: 09/04/2023] [Accepted: 03/21/2024] [Indexed: 04/19/2024]
Abstract
Background Electronic-prescribing (e-prescribing) is the most recent technological advancement in the medication use process. Its adoption and consequent realization of its potential benefits, however, mainly depend on the healthcare professionals' perception, willingness to accept, and engagement with the technology. Objectives This study is aimed at assessing the perception of healthcare professionals towards e-prescribing at the University of Gondar Comprehensive Specialized Hospital, Northwest Ethiopia, from June 1 to August 30, 2021. Method A cross-sectional study was conducted using a simple random sampling technique. A self-administered questionnaire was used for data collection. Data were entered into and analyzed by using the Statistical Package for the Social Sciences (SPSS® (IBM Corporation)) version 24. Both descriptive and inferential statistics like the Kruskal-Wallis and Mann-Whitney tests were used for data analysis. A statistical significance was declared at a p value < 0.05. Result From 401 participants, the majority of study participants had a neutral perception of e-prescribing. More than two-thirds (68.8%) of them had a neutral perception towards the perceived usefulness of e-prescribing with a median (interquartile range (IQR)) perceived usefulness of 43.0 (7.0) (maximum score = 60). The perceived ease of use of e-prescribing was also neutral in the case of more than three-fourths (79.8%) of participants with a median (IQR) perceived ease of use of 49.0 (6) (maximum score = 75). Similarly, more than half (56.6%) of the participants had a neutral perception towards the perceived fitness of e-prescribing with a median (IQR) perceived fitness of 15.0 (2.5) (maximum score = 15). The perception of the participants showed a significant difference based on their qualifications and work and computer use experience. Participants who heard about e-prescribing and e-prescribing software had a significantly higher mean rank score of perceived usefulness, perceived ease of use, and perceived fitness of e-prescribing. Participants who previously used e-prescribing had also a significantly higher mean rank score of perceived usefulness. Conclusion and Recommendation. The majority of healthcare professionals had a neutral perception of e-prescribing. The perception of healthcare professionals differs based on their qualifications, work and computer use experience, and their exposure to e-prescribing. The hospital should take all expectations and concerns of all HCPs into consideration and provide experience-sharing opportunities for all healthcare professionals who may potentially be involved in e-prescribing.

Predictors for participation in mass-treatment and female genital schistosomiasis re-investigation, and the effect of praziquantel treatment in South African adolescents. PLoS Negl Trop Dis 2024; 18:e0011798. [PMID: 38536861 PMCID: PMC11020363 DOI: 10.1371/journal.pntd.0011798] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/15/2023] [Revised: 04/16/2024] [Accepted: 03/12/2024] [Indexed: 04/18/2024] Open
Abstract
OBJECTIVE Female Genital Schistosomiasis (FGS) causes intravaginal lesions and symptoms that could be mistaken for sexually transmitted diseases or cancer. In adults, FGS lesions [grainy sandy patches (GSP), homogenous yellow patches (HYP), abnormal blood vessels and rubbery papules] are refractory to treatment. The effect of treatment has never been explored in young women; it is unclear if gynaecological investigation will be possible in this young age group (16-23 years). We explored the predictors for accepting anti-schistosomal treatment and/or gynaecological reinvestigation in young women, and the effects of anti-schistosomal mass-treatment (praziquantel) on the clinical manifestations of FGS at an adolescent age. METHOD The study was conducted between 2011 and 2013 in randomly selected, rural, high schools in Ilembe, uThungulu and Ugu Districts, KwaZulu-Natal Province, East Coast of South Africa. At baseline, gynaecological investigations were conducted in female learners in grades 8 to 12, aged 16-23 years (n = 2293). Mass-treatment was offered in the low-transmission season between May and August (a few in September, n = 48), in accordance with WHO recommendations. Reinvestigation was offered after a median of 9 months (range 5-14 months). Univariate, multivariable and logistic regression analysis were used to measure the association between variables. RESULTS Prevalence: Of the 2293 learners who came for baseline gynaecological investigations, 1045 (46%) had FGS lesions and/or schistosomiasis, 209/1045 (20%) had GSP; 208/1045 (20%) HYP; 772/1045 (74%) had abnormal blood vessels; and 404/1045 (39%) were urine positive. Overall participation rate for mass treatment and gynaecological investigation: Only 26% (587/2293) learners participated in the mass treatment and 17% (401/2293) participated in the follow up gynaecological reinvestigations. Loss to follow-up among those with FGS: More than 70% of learners with FGS lesions at baseline were lost to follow-up for gynaecological investigations: 156/209 (75%) GSP; 154/208 (74%) HYP; 539/722 (75%) abnormal blood vessels; 238/404 (59%) urine positive. The grade 12 pupil had left school and did not participate in the reinvestigations (n = 375; 16%). Follow-up findings: Amongst those with lesions who came for both treatment and reinvestigation, 12/19 still had GSP, 8/28 had HYP, and 54/90 had abnormal blood vessels. Only 3/55 remained positive for S. haematobium ova. Factors influencing treatment and follow-up gynaecological investigation: HIV, current water contact, water contact as a toddler and urinary schistosomiasis influenced participation in mass treatment. Grainy sandy patches, abnormal blood vessels, HYP, previous pregnancy, current water contact, water contact as a toddler and father present in the family were strongly associated with coming back for follow-up gynaecological investigation. Challenges in sample size for follow-up analysis of the effect of treatment: The low mass treatment uptake and loss to follow up among those who had baseline FGS reduced the chances of a larger sample size at follow up investigation. However, multivariable analysis showed that treatment had effect on the abnormal blood vessels (adjusted odds ratio = 2.1, 95% CI 1.1-3.9 and p = 0.018). CONCLUSION Compliance to treatment and gynaecological reinvestigation was very low. There is need to embark on large scale awareness and advocacy in schools and communities before implementing mass-treatment and investigation studies. Despite challenges in sample size and significant loss to follow-up, limiting the ability to fully understand the treatment's effect, multivariable analysis demonstrated a significant treatment effect on abnormal blood vessels.

Abstract
BACKGROUND Dermatitis caused by insects and mites, diagnosed as papular urticaria or scabies, is a common skin disease. However, there is still a lack of studies about the effects of weather and air pollution on outpatient visits for this disease. This study aims to explore the impacts of meteorological and environmental factors on daily visits of dermatitis outpatients. METHODS Analyses are conducted on a total of 43,101 outpatient visiting records during the years 2015-2020 from the largest dermatology specialist hospital in Guangzhou, China. Hierarchical cluster models based on Pearson correlation between risk factors are utilized to select regression variables. Linear regression models are fitted to identify the statistically significant associations between the risk factors and daily visits, taking into account the short-term effects of temperatures. Permutation importance is adopted to evaluate the predictive ability of these factors. RESULTS Short-term temperatures have positive associations with daily visits and exhibit strong predictive abilities. In terms of total outpatients, the one-day lagged temperature not only has a significant impact on daily visits, but also has the highest median value of permutation importance. This conclusion is robust across most subgroups except for subgroups of summer and scabies, wherein the three-day lagged temperature has a negative effect. By contrast, air pollution has insignificant associations with daily visits and exhibits weak predictive abilities. Moreover, weekdays, holidays and trends have significant impacts on daily visits, but with weak predictive abilities. CONCLUSIONS Our study suggests that short-term temperatures have positive associations with daily visits and exhibit strong predictive abilities. Nevertheless, air pollution has insignificant associations with daily visits and exhibits weak predictive abilities. The results of this study provide a reference for local authorities to formulate intervention measures and establish an environment-based disease early warning system.

Association between water insecurity and antiretroviral therapy adherence among pregnant and postpartum women in Greater Accra region of Ghana. PLOS GLOBAL PUBLIC HEALTH 2024; 4:e0002747. [PMID: 38190403 PMCID: PMC10773961 DOI: 10.1371/journal.pgph.0002747] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 05/24/2023] [Accepted: 11/30/2023] [Indexed: 01/10/2024]
Abstract
BACKGROUND Adherence to antiretroviral therapy (ART) can substantially reduce morbidity and mortality among women living with HIV (WLWH) and prevent vertical transmission of HIV. However, in sub-Saharan Africa (SSA), more than 50% of new mothers discontinue ART and HIV care after childbirth. The role of water insecurity (WI) in ART adherence is not well-explored. We examined the relationship between WI and ART adherence among pregnant and postpartum WLWH in Greater Accra region of Ghana. METHODS Using a cross-sectional survey, we recruited 176 pregnant and postpartum WLWH on ART across 11 health facilities. We examined the association between WI (measured using the Household Water Insecurity Experience Scale, and categorized as moderate and severe WI compard to low WI) and poor ART adherence (defined as scoring a below average observed CASE index score). Bivariate analysis was performed using chi-square test followed by multivariate logistic regression models. We included all variables with p-values less than 0.20 in the multivariate analysis. RESULTS Most (79.5%) of the pregnant and postpartum WLWH enrolled on ART, were urban residents. Over 2/3 were aged 30 years and older. Overall, 33.5% of respondents had poor ART adherence. Proportion of poor ART adherence was 19.4% among those with low WI, 44.4% in those with moderate WI, and 40.0% among those with high WI. Respondents with moderate household water insecurity had a greater odds of reporting poor ART adherence, as compared to those with low water insecurity (adjusted Odds ratio (aOR) = 2.76, 95%CI: 1.14-6.66, p = 0.024), even after adjusting for food insecurity. Similarly, respondents with high WI had a greater odds of reporting poor ART adherence, as compared to those with low water insecurity (aOR = 1.49, 95%CI: 0.50-4.48, p = 0.479), even after adjusting for food insecurity. CONCLUSION Water insecurity is prevalent among pregnant and postpartum WLWH and is a significant risk factor for poor ART adherence. Governments and other stakeholders working in HIV care provision should prioritize water security programming for WLWH along the HIV care continuum.

Abstract
Nontuberculous Mycobacteria (NTM) refer to bacteria other than all Mycobacterium species that do not cause tuberculosis or leprosy, excluding the species of the Mycobacterium tuberculosis complex, M. leprae and M. lepromatosis. NTM are ubiquitous and present in soils and natural waters. NTM can survive in a wide range of environmental conditions. The direct inoculum of the NTM from water or other materials is most likely a source of infections. NTMs are responsible for several illnesses, including pulmonary alveolar proteinosis, cystic fibrosis, bronchiectasis, chronic obstructive pneumoconiosis, and pulmonary disease. Recent reports suggest that NTM species have become insensitive to sterilizing agents, antiseptics, and disinfectants. The efficacy of existing anti-NTM regimens is diminishing and has been compromised due to drug resistance. New and recurring cases of multidrug-resistant NTM strains are increasing. Thus, there is an urgent need for ant-NTM regimens with novel modes of action. This review sheds light on the mode of antimicrobial resistance in the NTM species. Then, we discussed the repurposable drugs (antibiotics) that have shown new indications (activity against NTM strains) that could be developed for treating NTM infections. Also, we have summarised recently identified natural leads acting against NTM, which have the potential for treating NTM-associated infections.

Abstract
Objective To determine the etiologies and outcomes of liver disease in pregnancy in a developing country. Method A total of 336 consecutive pregnant women with liver disease were included in this prospective cohort study conducted at the Department of Gastroenterology, Jinnah Postgraduate Medical Center, Karachi from August 2019 to August 2021. Patients' baseline demographic, clinical, and laboratory data and outcomes were collected on a pre-designed questionnaire. Results Among all the pregnant females, the most common liver disease was acute hepatitis E virus (HEV) infection (37.2%), followed by preeclampsia (PEC)/eclampsia (EC), hemolysis, elevated liver enzymes & low platelets (HELLP) syndrome, and hyperemesis gravidarum (HG). The most common maternal complications were fulminant hepatic failure (FHF) in 14.9% and placental abruption in 11.0%. Fetal complications included intrauterine death (IUD) in 20.8% and preterm birth in 8.6%. The maternal and neonatal mortality rates were 11.6% and 39.6%, respectively. Among the predictors, low maternal weight, low body mass index (BMI), and low hemoglobin (Hb) were associated with increased maternal mortality. Low fetal weight, height, maternal systolic blood pressure (SBP), and low maternal Hb were independent predictors of fetal mortality. Conclusion In our cohort of pregnant females in a tertiary care medical center, acute HEV was the most common liver disease, followed by PEC/EC, HELLP, and HG. Maternal and fetal deaths were alarming in this group of patients and demanded careful management.

Abstract
One of the most common primary resistance mechanism of multi-drug resistant (MDR) Gram negative pathogenic bacteria to combat β-lactam antibiotics, such as penicillins, cephalosporins and carbapenems is the generation of β- lactamases. The uropathogenic E. coli is mostly getting multi-drug resistance due to the synthesis of AmpC β-lactamases and therefore new antibiotics and inhibitors are needed to treat the evolving infections. The current study was designed for targetting AmpC β-lactamase of E. coli using molecular docking based virtual screening, linking fragments for designing novel compounds and binding mode analysis using molecular dynamic simulation with target protein. The FCH group all-purpose fragment library consisting of 9388 fragments has been screened against AmpC β-lactamase protein of E. coli and the antibiotics and anti-infectives used in treatment of Urinary tract Infections (UTIs) were also screened with AmpC β-lactamase protein. Among the 9388 fragments, 339 fragment candidates were selected and linked with cefepime antibiotic having maximum binding affinity for AmpC target protein. Computational analysis of interactions as well as molecular dynamics (MD) simulations were also conducted for identifying the most promising ligand-pocket complexes from docking investigations to comprehend their thermodynamic properties and verify the docking outcomes as well. Overall, the linked complexes (LCs) showed good binding interactions with AmpC β-lactamase. Interestingly, our fragment-based LCs remained relatively stable in comparison with cefepime antibiotic. Moreover, S12 fragment linked complex remained the most stable during 50 ns with remarkable number of interactions indicating it as promising candidate in novel lead discovery against MDR E. coli infections.

Abstract
Background Socio-demographic characteristics may have an impact on HIV-positive people's prognosis and survival. In addition, food insecurity could make it harder for HIV patients to stick to their treatment plans as effectively as possible. Objective This research aimed to determine the association between socio-demographic and food insecurity with adherence to antiretroviral therapy among people living with HIV on ART in Ahmadu Bello University Teaching Hospital Zaria, Kaduna State, Nigeria. Method Using a cross-sectional design, a systematic random sampling method was used to select respondents aged 18-64 years on antiretroviral therapy for at least six months at Ahmadu Bello University Teaching Hospital Zaria, Kaduna State, Nigeria, outpatients of the President's Emergency Plan for AIDS Relief clinic. Socio-demographic, food insecurity status and adherence to ART was obtained using self-administered questionnaire. Descriptive statistics, chi-square test, and multiple logistic regression were used for data analysis. Results Among the 385 people who took part in the study, about 67.5% of females and 32.5% of males took part in the survey, respectively. About 54% of adults adhered to ART. The majority of the respondents (87.0%) had a low level of food security. Food insecurity (OR = 1.2, p = <0.05), government employment (OR = 2.842, p = <0.01), self-employment (OR = 2.6, p = <0.001), and being divorced or widowed (OR = 2.0, p = <0.01) were all significantly associated with ART adherence. Conclusion Food insecurity, employment, and marital status influenced adherence to ART. As a result, health care providers and HIV control programme implementers must continually emphasis and encourage strict adherence.

Abstract
Mother-to-child transmission of HIV remains the primary contributor to HIV infections in children, globally. Despite the progress made to reduce new HIV infections in children, barriers to utilization of the Elimination of Mother-to-Child Transmission service remain the bottleneck that affects the program's effectiveness. This study aims to develop a framework to address barriers to the utilization of the Elimination of Mother-to-Child Transmission of HIV services among pregnant women and lactating mothers in Gauteng province. A convergent parallel mixed methods design will be employed in phases. Phase 1(a) quantitative will be collected from pregnant women and lactating mothers to describe barriers associated with poor utilization of elimination of mother-to-child transmission services and a potential strategy to facilitate EMTCT utilization; phase 1(b) qualitative data will be collected to explore reasons for poor utilization of EMTCT services and perceived strategy to enhance women's utilization of elimination of mother-to-child transmission services. Quantitative data will be analyzed using Stata software version 14.0 and qualitative data will be analyzed thematically and then results will be integrated. Phase 2: will focus on the development of a framework; Phase 3: will validate the developed framework. The conclusion and recommendations will be based on the findings of the study.

Abstract
This retrospective cohort study investigated older people living with HIV/AIDS (PLWHA) characteristics, HIV care, and treatment outcomes among all cases between 1996 and 2019 in Guangxi, China. Secondary data were extracted from two national surveillance databases. Older (≥50 years old) and younger (18-49 years old) PLWHA were compared regarding demographic and behavioral characteristics, HIV care, virologic failure, and all-cause mortality. Older PLWHA accounted for 41.6% of all HIV cases (N = 144,952) between 1996 and 2019. The proportion of older cases increased from 10.4% to 64.8% for men and from 2.4% to 66.7% for women between 2002 and 2019. Heterosexual contact accounted for 96.0% of older adults. Moreover, older PLWHA had a lower median CD4 count at the HIV diagnosis (193 vs. 212 cells/μL, p < 0.0001) and were less likely to receive antiretroviral therapy (ART) than younger adults (72.1% vs. 86.1%, p < 0.001). The all-cause mortality risk of older PLWHA was 2.87 times of younger adults [adjusted hazard ratio (AHR) 2.87; 95% confidence interval (CI) 2.76-2.98]. In addition, older PLWHA reported an 18% increase in odds for virologic failure than younger adults (AOR 1.18; 95% CI 1.08-1.30). Therefore, enhanced HIV prevention and care are urgently needed in older people.

Abstract
Zoonoses are likely to cause a substantial burden on both human and animal health systems in Somalia, given the close proximity between the pastoralist majority and their livestock. However, decades of instability leading to weak disease surveillance have meant that data on the burden of zoonoses is lacking. The aim of this scoping review was to assess and synthesize the available literature on the presence and burden of zoonoses in Somalia. We used keywords to search Web of Science for relevant publications. Studies were included if they contained relevant data on a zoonosis and were undertaken in Somalia or were undertaken in another country where exposure could reasonably be assumed to have occurred in Somalia (e.g., migrants/refugees, returning soldiers, exported animals). Studies were not included if they focused on Somali ethnic communities permanently living elsewhere or if zoonotic aspects were not considered. We extracted data on disease(s) reported, geographic focus, data reported (human, animal, environment), study design and author affiliation. A total of 22 zoonotic infections were documented in 76 publications. The most frequently studied diseases were Rift Valley Fever (n = 15, 17%), brucellosis (n = 13, 14%) and hepatitis E (n = 10, 11%). Around 30% of papers reported data from relevant populations outside Somalia. Only 18 papers undertook laboratory analysis within Somalia. Most papers reported data on humans (45%) and animals (36%) with limited research on the environmental domain. Descriptive studies (47%) dominated and most were led by non-Somali researchers (89% in first authors and 95% of last authors). This study highlights the need for well-designed zoonoses research in Somalia supported by capacity building of local researchers and investments in diagnostic laboratories.

Antimicrobial Resistance in Rapidly Growing Nontuberculous Mycobacteria among Domestic and Wild Animals Emphasizing the Zoonotic Potential. Microorganisms 2023; 11:2520. [PMID: 37894179 PMCID: PMC10609087 DOI: 10.3390/microorganisms11102520] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/30/2023] [Revised: 09/29/2023] [Accepted: 10/08/2023] [Indexed: 10/29/2023] Open
Abstract
Non-tuberculous mycobacteria (NTM) are opportunistic pathogens capable of causing infections in humans and animals. The aim of this study was to demonstrate the potential role of domestic and wild animals as a reservoir of multiple resistant, rapidly growing NTM strains representing a potential zoonotic threat to humans. A total of 87 animal isolates belonging to 11 rapidly growing species (visible colonies appear within three to seven days) were genotyped and tested for susceptibility to the 15 most commonly used antibiotics in the treatment of such infections in a human clinic. By determining the antimicrobial susceptibility, the most prevalent resistance was found to cephalosporins (>50%), followed by amoxicillin-clavulanate (31.0%), clarithromycin (23.0%), tobramycin (14.9%) and doxycycline (10.3%). Resistance to imipenem, ciprofloxacin, minocycline and linezolid was notably lower (<7.0%). All tested isolates were susceptible to amikacin and moxifloxacin. The most frequent resistance was proved in the most pathogenic species: M. fortuitum, M. neoaurum, M. vaccae and M. porcinum. Meanwhile, other species displayed a higher sensitivity rate. No significant resistance differences between domestic and wild animals were found. The established significant frequency of resistance highlights the significant zoonotic potential posed by circulating rapidly growing NTM strains, which could lead to challenges in the treatment of these infections.

Abstract
Purpose The study explored the psychosocial profile of women who defaulted Option B+ HIV treatment at Chitungwiza Municipality clinics in Zimbabwe. Option B+ is a strategy to prevent mother-to-child transmission (PMTCT) of HIV to reduce MTCT rate to less than or equal to 5%. Methods An interpretive phenomenological analysis (IPA) design was used. Data were collected from 04 September to 12 October 2020 on twelve purposively selected HIV-positive breastfeeding women aged 18 to 40 years, who defaulted Option B+ HIV treatment. Unstructured individual face-to-face interviews were utilised. Data were analysed thematically using the interpretive phenomenological analysis framework for data analysis. Results The study findings revealed that participants experienced the following: psychosocial and emotional challenges due to HIV positive results, shown emotional distress and suicidal tendencies which affected their mental health. Their relationship was derailed due to abuse, infidelity, partner's high-risk behaviour and to lack of support stemming from their partners and family members. Conclusion Strengthening adherence support interventions and effective counselling on HIV-positive status disclosure and male partner involvement is important for retaining women in care and for improving their quality of life. Comprehensive, integrated, and tailor-made interventions should be adopted. Couple HIV counselling and testing should be encouraged. Psychosocial and mental health should be encouraged. Furthermore, community sensitization, risk reduction behaviour, education on purpose and side effects of ART as well as the benefits of Option B+ to new enrolments should be intensified and strengthened to minimize defaulting of treatment and LTFUP. Vigorous patient tracing and visit reminders help retain women in care.

Abstract
A 69-year-old patient presented with a 9-month history of constitutional symptoms and a 3-week history of increasing abdominal and back pain. He had a history of bacillus Calmette-Guérin immunotherapy for bladder cancer 9 months earlier. An infrarenal mycotic aneurysm was detected by positron emission tomography-computed tomography. His abdominal aorta was reconstructed using a tube graft tailored from a bovine pericardium sheet. We chose this graft because of its acellular nature and reduced risk of postoperative infection. The culture from the aortic wall yielded acid fast bacilli, and he was treated with antituberculosis medication. His postoperative recovery was uneventful, except for chylous ascites.

Abstract
The dynamics of infectious disease in a population critically involves both within-host pathogen replication and between host pathogen transmission. While modeling efforts have recently explored how within-host dynamics contribute to shaping population transmission, fewer have explored how ongoing circulation of an epidemic infectious disease can impact within-host immunological dynamics. We present a simple, influenza-inspired model that explores the potential for re-exposure during a single, ongoing outbreak to shape individual immune response and epidemiological potential in non-trivial ways. We show how even a simplified system can exhibit complex ongoing dynamics and sensitive thresholds in behavior. We also find epidemiological stochasticity likely plays a critical role in reinfection or in the maintenance of individual immunological protection over time.

Abstract
Despite Helicobacter pylori infection remains asymptomatic in most people, it is associated with an increased risk of gastric cancer. Considering Egypt had the highest prevalence of H. pylori in healthy asymptomatic population in adults and pediatric age in past studies and currently salivary ELISA could be used for diagnosis of Oral H. pylori infection. Moreover, some researchers speculated that dentists and dental students might be at a higher risk for oral H. pylori infection because they are the most frequently exposed ones to saliva and dental plaque. This study aimed to determine risk factors associated with frequency of H. pylori among a sample of dental students for better management of the disease. 83 participants, with age (21-25 years), attending Faculty of Dentistry, Fayoum University were recruited. A structured questionnaire was used to collect information on sociodemographic parameters and risk factors for H. pylori. Direct inquiry about dyspeptic symptoms were done. Saliva samples were collected and tested for H. pylori antibodies. Overall seroprevalence was 22.9%. Participants in internship were more prone to be positive (p = 0.005). 32.6% of urban residents versus 10.8% of rural were H. pylori positive (p = 0.019). 75.0% of previous history of H. pylori infection versus 14.1% of those with no history were H. pylori positive p < 0.001. 70% of positive H. pylori participants reported positive clinical symptoms that were statistically significant. This study suggests that middle income, previous history of H. pylori and clinical symptoms of dyspepsia are risk factors of oral H. pylori with a decline in its prevalence in Egypt.

Abstract
We evaluated the clinical characteristics and treatment outcomes of 35 patients diagnosed with Mycobacterium fortuitum-pulmonary disease (M. fortuitum-PD). Prior to treatment, all isolates were sensitive to amikacin and 73% and 90% were sensitive to imipenem and moxifloxacin, respectively. Approximately two-thirds of the patients (24 of 35) remained stable without antibiotic treatment. Of 11 patients requiring antibiotic treatment, the majority (81%, 9 of 11) achieved a microbiological cure with susceptible antibiotics. IMPORTANCE Mycobacterium fortuitum (M. fortuitum) is a rapidly growing mycobacterium that causes M. fortuitum-pulmonary disease (PD). It is common among individuals with preexisting lung conditions. Limited data exist regarding treatment and prognosis. Our study examined patients with M. fortuitum-PD. Two-thirds of them remained stable without antibiotics. Among those requiring treatment, 81% achieved a microbiological cure with suitable antibiotics. In many cases, M. fortuitum-PD follows a stable course without antibiotics, and when necessary, a favorable treatment response can be achieved with the appropriate antibiotics.

Reducing morbidity and mortality from HIV-associated TB requires strong collaboration between TB and HIV services at all levels with fully integrated, people-centered models of care. METHODS This is a qualitative study design using principles of ethnography and the application of aggregate complexity theory. A total of 54 individual interviews with healthcare workers and patients took place in five primary healthcare facilities in the O.R. Tambo district. The participants were purposively selected until the data reached saturation point, and all interviews were tape-recorded. Quantitative analysis of qualitative data was used after coding ethnographic data, looking for emerging patterns, and counting the number of times a qualitative code occurred. A Likert scale was used to assess the perceived quality of TB/HIV integration. Regression models and canonical discriminant analyses were used to explore the associations between the perceived quality of TB and HIV integrated service delivery and independent predictors of interest using SPSS® version 23.0 (Chicago, IL) considering a type I error of 0.05. RESULTS Of the 54 participants, 39 (72.2%) reported that TB and HIV services were partially integrated while 15 (27.8%) participants reported that TB/HIV services were fully integrated. Using the Likert scale gradient, 23 (42.6%) participants perceived the quality of integrated TB/HIV services as poor while 13 (24.1%) and 18 (33.3%) perceived the quality of TB/HIV integrated services as moderate and excellent, respectively. Multiple linear regression analysis showed that access to healthcare services was significantly and independently associated with the perceived quality of integrated TB/HIV services following the equation: Y = 3.72-0.06X (adjusted R2 = 23%, p-value = 0.001). Canonical discriminant analysis (CDA) showed that in all 5 municipal facilities, long distances to healthcare facilities leading to reduced access to services were significantly more likely to be the most impeding factor, which is negatively influencing the perceived quality of integrated TB/HIV services, with functions' coefficients ranging from 9.175 in Mhlontlo to 16.514 in KSD (Wilk's Lambda = 0.750, p = 0.043). CONCLUSION HIV and TB integration is inadequate with limited access to healthcare services. Full integration (one-stop-shop services) is recommended.

[PMID: 37431501 PMCID: PMC10329832 DOI: 10.2147/hiv.s406372] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/26/2023] [Accepted: 06/09/2023] [Indexed: 07/12/2023] Open
Abstract
Background Even though there are many patients on second-line antiretroviral therapy (ART) in Ethiopia, there is a paucity of evidence on the rate of viral resuppression and its predictors. Therefore, this study aimed to determine a time to viral resuppression and identify predictors among adults on second-line ART in South Wollo public hospitals, northeast Ethiopia. Methods A retrospective-cohort study design was employed using patients enrolled in second-line ART from August 28, 2016 to April 10, 2021. Data were collected using a structured data-extraction checklist with a sample size of 364 second-line ART patients from February 16 to March 30, 2021. EpiData 4.6 was used for data entry and Stata 14.2 was used for analysis. The Kaplan-Meier method was used for estimating time to viral resuppression. The Shönfield test was used to check the proportional-hazard assumption, and the "no interaction" stratified Cox assumption was checked using the likelihood-ratio test. A stratified Cox model was applied to identify predictors of viral resuppression. Results Median time to viral re-suppression in patients on a second-line regimen was 10 (IQR 7-12) months. BeingFemale (AHR 1.31, 95% CI 1.01-1.69), low viral load count at switch (AHR 1.98, 95% CI 1.26-3.11), normal-range BMI at switch (AHR 1.42, 95% CI 1.03-1.95), and lopinavir-based second-line regimen (AHR 1.72, 95% CI 1.15-2.57) were significant predictors of early time to viral resuppression after stratification by WHO stage and adherence level. Conclusion Median time to viral re-suppression after switching to second-line ART was 10 months. In the stratified Cox model, female sex, baseline viral copies, second-line regimen type, and BMI at switch were statistically significant predictors of time to viral resuppression. Different stakeholders working on the HIV program should maintain viral resuppression by addressing significant predictors, and ART clinicians should consider ritonavir-boosted lopinavir based second-line ART for newly switched patients.

Abstract
Background To achieve an effective treatment outcome, Antiretroviral Therapy (ART) for people living with the Human immunodeficiency virus (HIV) needs at least a 95% adherence level. The aim was to assess adherence to antiretroviral therapy and its associated factors among patients accessing treatment at Health centers in East Gojjam Zone, Northwest Ethiopia. Methods A community-based cross-sectional study was conducted on 770 HIV-positive patients from April 1 to May 10, 2019, in East Gojjam Zone. The study participants were selected by simple random computerized sampling methods. Primary data was collected from the patients through face-to-face interviews and home-to-home visits. Bivariable and multivariable binary logistic regression analyses were done. Independent variables with a P-value of <0.2 in bivariable binary logistic regression analysis were considered for multivariable binary logistic regression analysis. A P-value of <0.05 was used as the cut-off point for the presence of statistical significance. Results About 396 (51.8%) of the study participants had good adherence. Being 18-24 years old [Adjusted Odd Ratio (AOR) = 0.43; 95% CI = 0.21-0.86], having a marital status of being widowed (AOR = 0.29; 95% CI = 0.14-0.58), having a disease duration of >10 years (AOR = 0.47; 95% CI = 0.24-0.94), taking a drug regimen of Tenofovir (TDF) + Lamivudine (3 TC) + Nevirapine (NVP) (AOR = 2.94; 95% CI = 1.406.15), not being socially stigmatized (AOR = 0.52; 95% CI = 0.34-0.78), and having not encountered an opportunistic infection (AOR = 3.91; 95% CI = 2.68-5.72) were significant factors. Conclusions The level of adherence was low. Opportunistic infection prevention, reduction of social stigma, and other intervention activities should be strengthened to increase the level of adherence.

Abstract
Background Bloodstream infection (BSI) is a prevalent cause of admission in hemodialysis (HD) patients and is associated with increased morbidity and mortality. This study aimed to establish a diagnostic, predictive model for the early identification of BSI in HD patients. Methods HD patients who underwent blood culture testing between August 2018 and March 2022 were enrolled in this study. Machine learning algorithms, including stepwise logistic regression (SLR), Lasso logistic regression (LLR), support vector machine (SVM), decision tree, random forest (RF), and gradient boosting machine (XGboost), were used to predict the risk of developing BSI from the patient's clinical data. The accuracy (ACC) and area under the subject working curve (AUC) were used to evaluate the performance of such models. The Shapley Additive Explanation (SHAP) values were used to explain each feature's predictive value on the models' output. Finally, a simplified nomogram for predicting BSI was devised. Results A total of 391 HD patients were enrolled in this study, of whom 74 (18.9%) were diagnosed with BSI. The XGboost model achieved the highest AUC (0.914, 95% confidence interval [CI]: 0.861-0.964) and ACC (86.3%) for BSI prediction. The four most significant co-variables in both the significance matrix plot of the XGboost model variables and the SHAP summary plot were body temperature, dialysis access via a non-arteriovenous fistula (non-AVF), the procalcitonin levels (PCT), and neutrophil-lymphocyte ratio (NLR). Conclusions This study created an effective machine-learning model for predicting BSI in HD patients. The model could be used to detect BSI at an early stage and hence guide antibiotic treatment in HD patients.

Association between the Treatment of Rosacea and Eradication of Helicobacter Pylori Infection. Adv Biomed Res 2023; 12:173. [PMID: 37564456 PMCID: PMC10410436 DOI: 10.4103/abr.abr_236_22] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/17/2022] [Revised: 11/07/2022] [Accepted: 11/28/2022] [Indexed: 08/12/2023] Open
Abstract
Background Rosacea is a multifactorial skin inflammatory disorder with an unknown cure. Genetics and environmental factors such as microorganisms are involved in the rosacea etiology, for example, Helicobacter pylori have been suggested in rosacea progression. The present study investigated the relationship between H. pylori eradication and rosacea patient's improvement. Materials and Methods H. pylori infection was investigated in 60 rosacea patients and 65 sex- and age-matched healthy control through enzyme-linked immunosorbent assay (ELISA) and HpSag tests. After infection confirmation, randomly half of the rosacea patients were treated for H. pylori eradication (test), and others received standard treatment (control). HpSag and ELISA tests were repeated after infection eradication and disease flow was surveyed for 60 days. The groups were compared using the ANOVA (Analysis Of Variance) test at the significant level of P < 0.05. Results At the baseline, the mean of immunoglobulin G (IgG) (59.27 ± 41.4 RU/mL) and immunoglobulin M (IgM) (11.55 ± 6.1 RU/mL) in rosacea patients was higher than the level of IgG (41.38 ± 54.33 RU/mL) and IgM (8.11 ± 8.91 RU/mL) in healthy control (P < 0.04) and (P < 0.01), respectively. Also, the values for H. pylori infection were positive in all patients and 10 healthy controls. The mean titer of IgM and IgG in the test and control patients groups were different at baseline and after treatment. Furthermore, in the test patients group, the mean of IgG was reduced in active rosacea after treatment, and 63.9% of active patients showed rosacea remission after H. pylori eradication. Conclusion Data suggest the exacerbating role of H. pylori in rosacea, and its eradication along with other therapeutic methods causes rosacea improvement.

[PMID: 37349792 PMCID: PMC10286334 DOI: 10.1186/s12985-023-02064-5] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/30/2023] [Accepted: 05/07/2023] [Indexed: 06/24/2023] Open
Abstract
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.

Abstract
BACKGROUND Knowing what to eat and realizing the significance of healthful eating habits are among the important steps to promoting eating behavior. The current study aims to assess the nutrition knowledge (NK) among a convenient sample in four different countries, determine the association between different demographic factors and NK, and investigate the need for future interventions on nutrition in the four selected countries. METHODS A cross-sectional multi-national survey study among a convenient sample of 8,191 subjects from Egypt, Syria, Saudi Arabia, and Jordan who undertook surveys between January 2019 and January 2020. A pre-tested interview questionnaire was utilized for data collection from study participants. It included three sections: i) Sociodemographic characteristics:. ii). Section two included twenty-one questions related to NK.. iii). Section three included one question about NK sources. RESULTS About three-quarters showed inadequate nutrition knowledge (73.1%). Youth (15-24 yrs.) were more dependent on social media, with 87% using it as a primary source of NK, while adults (≥ 25 yrs.) demonstrated that 43% of them used social media. In contrast, TV was more prominent among them, with participants' characteristics such as living with parents, body mass index, and country of residence showing no association with NK. However, female sex, education, and reading nutrition articles are significantly correlated with adequate knowledge (p < 0.001). Significant predictors of satisfactory knowledge were age, sex, education, living with parents, and reading nutrition articles. CONCLUSION The study revealed low levels of NK indicating an urgent need to implement educational programs to promote nutrition knowledge. As NK is a modifiable determinant of diet intake and can positively impact the need for developing strategies in counselling and raising awareness among the general population to improve their health status.

HIV AIDS (Auckl) 2023; 15:293-311. [PMID: 37312814 PMCID: PMC10259591 DOI: 10.2147/hiv.s407535] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/07/2023] [Accepted: 05/28/2023] [Indexed: 06/15/2023] Open
Abstract
Introduction HIV serostatus disclosure is a fundamental HIV prevention and care strategy yet with a paucity of literature. This study comprehended the factors associated with HIV serostatus disclosure to sexual partners among young people aged 15-24 years on anti-retroviral therapy (ART). Methods This explanatory sequential study utilized quantitative data from 238 young people who had been on ART for over 12 months and were sexually active for at least 6 months in seven districts of Central Uganda. Pearson's Chi-square and multinomial logistic regression analysis at α=0.05 was used to determine the factors associated with serostatus disclosure among study participants. Qualitative data from 18 young people were collected using an in-depth interview guide and analyzed thematically. Results Non-disclosure was at 26.9%, one-way disclosure was at 24.4%, and two-way disclosure was at 48.7%. Participants who contracted HIV from their partners were three times more likely (RRR=2.752; 95% CI: 1.100-6.888) to have one-way disclosure than non-disclosure, compared to those who had a perinatal infection. Those who contracted HIV from their partners were twice more likely (RRR=2.357; 95% CI: 1.065-5.214) to have two-way disclosure than non-disclosure, compared to those who had a perinatal infection. Participants who stayed with their partners were four times more likely (RRR=3.869; 95% CI: 1.146-13.060) to have two-way disclosure than non-disclosure, compared to those who stayed with their parents. Young people disclosed because they were tired of secrecy and desired treatment adherence and did not disclose due to fear of stigma and losing their partners' support. Conclusion Many sexually active young people on ART did not disclose their HIV-positive status to sexual partners mainly due to poverty, having multiple-sexual partners, and stigma. Interventions fighting stigma, multiple-sexual relationships, and poverty among sexually active young people on ART should be strengthened.

Abstract
Objective Crimean-Congo hemorrhagic fever (CCHF) is a zoonotic disease associated with a high fatality rate. CCHF is endemic in Afghanistan, and its morbidity and mortality have increased recently but there is limited data about the characteristics of fatal cases. We aimed to report the clinical and epidemiological features of fatal CCHF cases who were admitted to Kabul Referral Infectious Diseases (Antani) Hospital. Methods This is a retrospective cross-sectional study. The demographic and presenting clinical and laboratory features of 30 fatal CCHF cases diagnosed by reverse transcription polymerase chain reaction (RT-PCR) or enzyme-linked immunosorbent assay (ELISA) tests were collected from the patients' records between March 2021 and March 2023. Results During the study period, a total of 118 laboratory-confirmed CCHF patients were admitted to Kabul Antani Hospital of whom 30 patients (25 males, 5 females) consequently died, indicating a 25.4% case fatality rate (CFR). The age of the fatal cases ranged from 15 to 62 years and their mean age was 36.6 ± 11.7 years. Concerning occupation, the patients were butchers (23.3%), animal dealers (20%), shepherds (16.6%), housewives (16.6%), farmers (10%), student (3.3%), and others (10%). The clinical symptoms of the patients on admission were fever (100%), generalized body pain (100%), fatigue (90%), bleeding (any type) (86.6%), headache (80%), nausea/vomiting (73.3%), and diarrhea (70%). The initial abnormal laboratory findings were leukopenia (80%), leukocytosis (6.6%), anemia (73.3%), and thrombocytopenia (100%), raised hepatic enzymes (ALT & AST) (96.6%) and prolonged prothrombin time/international normalized ratio (PT/INR) (100%). Conclusion The hemorrhagic manifestations associated with low platelet and raised PT/INR levels are linked with fatal outcomes. A high index of clinical suspicion is required to recognize the disease at an early stage and to begin the treatment promptly for reducing mortality.

Assessing West Nile virus (WNV) and Usutu virus (USUV) exposure in bird ringers in the Netherlands: a high-risk group for WNV and USUV infection? One Health 2023; 16:100533. [PMID: 37363259 PMCID: PMC10288042 DOI: 10.1016/j.onehlt.2023.100533] [Citation(s) in RCA: 5] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/30/2022] [Revised: 03/16/2023] [Accepted: 03/30/2023] [Indexed: 06/28/2023] Open
Abstract
Introduction In 2020, the first Dutch West Nile virus (WNV) infected birds were detected through risk-targeted surveillance of songbirds. Retrospective testing of patients with unexplained neurological disease revealed human WNV infections in July and August 2020. Bird ringers are highly exposed to mosquito bites and possibly avian excrements during ringing activities. This study therefore investigates whether bird ringers are at higher risk of exposure to WNV and Usutu virus (USUV). Methods Dutch bird ringers were asked to provide a single serum sample (May - September 2021) and to fill out a survey. Sera were screened by protein microarray for presence of specific IgG against WNV and USUV non-structural protein 1 (NS1), followed by focus reduction virus neutralization tests (FRNT). Healthcare workers (2009-2010), the national immunity cohort (2016-2017) and blood donors (2021) were used as control groups without this occupational exposure. Results The majority of the 157 participating bird ringers was male (132/157, 84%) and the median age was 62 years. Thirty-seven participants (37/157, 23.6%) showed WNV and USUV IgG microarray signals above background, compared to 6.4% (6/94) in the community cohort and 2.1% (2/96) in blood donors (p < 0.01). Two seroreactive bird ringers were confirmed WNV or USUV positive by FRNT. The majority of seroreactive bird ringers travelled to EU countries with reported WNV human cases (30/37, 81%) (p = 0.07). No difference was observed between bird ringers with and without previous yellow fever vaccination. Discussion The higher frequency of WNV and/or USUV IgG reactive bird ringers indicates increased flavivirus exposure compared to the general population, suggesting that individuals with high-exposure professions may be considered to complement existing surveillance systems. However, the complexity of serological interpretation in relation to location-specific exposure (including travel), and antibody cross-reactivity, remain a challenge when performing surveillance of emerging flaviviruses in low-prevalence settings.

Rate of occult hepatitis B virus infection among individuals with tuberculosis in northeastern Iran: A molecular epidemiological study. J Virus Erad 2023; 9:100333. [PMID: 37408699 PMCID: PMC10319180 DOI: 10.1016/j.jve.2023.100333] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/01/2023] [Revised: 05/31/2023] [Accepted: 06/14/2023] [Indexed: 07/07/2023] Open
Abstract
One third of the world population has a history of exposure to the hepatitis B virus (HBV), and two billion people are infected with latent tuberculosis (TB). Occult hepatitis B infection (OBI) is defined as the presence of replicative-competent HBV DNA in the liver with detectable or undetectable HBV DNA in the serum of individuals testing negative for the HBV surface antigen (HBsAg). Screening with HBV DNA could identify OBI and significantly reduce carriers and complications of chronic hepatitis B (CHB). This study aims to assess HBV serological markers and OBI molecular diagnosis among people with TB in Mashhad, northeastern Iran. We have performed HBV serological markers (HBsAg, HBc antibodies (Ab) and HBs Ab) in 175 participants. Fourteen HBsAg+ sera were excluded for further analysis. The presence of HBV DNA (C, S, and X gene regions) was assessed by the qualitative real-time PCR (qPCR) method. Frequencies of HBsAg, HBc, and HBs Ab were 8% (14/175), 36.6% (64/175), and 49.1% (86/175), respectively. Among these 42.9% (69/161) were negative for all HBV serological markers. The S, C, and X gene regions were positive in 10.3% (16/156), 15.4% (24/156), and 22.4% (35/156) of participants, respectively. The total OBI frequency was estimated at 33.3% (52/156) when based on detecting one HBV genomic region. Twenty-two and 30 participants had a seronegative and seropositive OBI, respectively. Thorough screening of high-risk groups with reliable and sensitive molecular methods could lead to OBI identification and decrease CHB long-term complications. Mass immunization remains critical in preventing, reducing, and potentially eliminating HBV complications.

Assessing the combined effect of household cooking fuel and urbanicity on acute respiratory symptoms among under-five years in sub-Saharan Africa. Heliyon 2023; 9:e16546. [PMID: 37346351 PMCID: PMC10279788 DOI: 10.1016/j.heliyon.2023.e16546] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/16/2022] [Revised: 05/02/2023] [Accepted: 05/18/2023] [Indexed: 06/23/2023] Open
Abstract
Background This study sought to investigate the association between urbanicity (rural-urban residency), the use of solid biomass cooking fuels and the risk of Acute Respiratory Infections (ARIs) among children under the age of 5 in sub-Saharan Africa (SSA). Methods Cross-sectional data from the most recent surveys of the Demographic and Health Survey Program conducted in 31 sub-Saharan African countries were pooled for the analysis. The outcome variables, cough and rapid short breath were derived from questions that asked mothers if their children under the age of 5 suffered from cough and short rapid breath in the past two weeks preceding the survey. To examine the associations, multivariable negative log-log regression models were fitted for each outcome variable. Results Higher odds ratios of cough occurred among children in urban households that use unclean cooking fuel (aOR = 1.05 95% CI = 1.01, 1.08). However, lower odds ratios were observed for rural children in homes that use clean cooking fuel (aOR = 0.93 95% CI = 0.87, 0.99) relative to children in urban homes using clean cooking fuel. We also found higher odds ratios of short rapid breaths among children in rural households that use unclean cooking fuel compared with urban residents using clean cooking fuel (aOR = 1.12 95% CI = 1.08, 1.17). Conclusion Urbanicity and the use of solid biomass fuel for cooking were associated with an increased risk of symptoms of ARIs among children under five years in SSA. Thus, policymakers and stakeholders need to design and implement strategies that minimize children's exposure to pollutants from solid biomass cooking fuel. Such interventions could reduce the burden of respiratory illnesses in SSA and contribute to the realization of Sustainable Development Goal 3.9, which aims at reducing the number of diseases and deaths attributable to hazardous chemicals and pollution of air, water and soil.

Abstract
Purpose Blood transfusion; is considered an organ transplant. In coronary bypass surgery, large volumes of homologous blood transfusion may be required due to excessive bleeding. The large number of use of homologous blood transfusion in open heart surgery and the awareness of its various harmful effects have prompted researchers to conduct research on the use of autologous blood. With autologous transfusion, blood diseases, incompatibility, immunosuppression and organ damage can be prevented and the patient can be extubated earlier in the postoperative period. Methods Between January 2020 and January 2016, a total of 176 patients, 56 in the treatment group (with autologous blood transfusion) and 120 in the control group, whose information could be reached from hospital records were investigated retrospectively. Results No statistical difference was found between the mean intubation SO2 and PO2 values of the groups. On the contrary, considering the mean intubation times in the intensive care unit of both groups, the patients who underwent autologous blood transfusion were extubated at a statistically significant earlier time. Conclusion Autologous blood transfusion is a safe method in selected patients as well. Thanks to this method, patients are protected from complications associated with homologous blood transfusion. It is believed that performing autologous blood transfusion in selected patients undergoing open-heart surgery can decrease the number of postoperative transfusions, frequency of transfusion-related complications (especially in the lungs), and mean intubation times.

Abstract
Background Arboviruses are endemic in Uganda; however, little is known about their epidemiology, seasonality and spatiotemporal distribution. Our study sought to provide information on arbovirus outbreaks from acute clinical presentations. Methods Immunoglobulin M (IgM) and confirmatory Plaque Reduction Neutralisation Test (PRNT) results for arbovirus diagnosis of samples collected from patients attending sentinel sites from 2016-19 were analysed retrospectively. Demographic data were analysed with SaTScan and SPSS software to determine the epidemiology and spatiotemporal distribution of arboviruses. Results Arbovirus activity peaked consistently during March-May rainy seasons. Overall, arbovirus seroprevalence was 9.5%. Of 137 IgM positives, 52.6% were confirmed by PRNT, of which 73.6% cases were observed in central Uganda with Yellow Fever Virus had the highest prevalence (27.8%). The 5-14 age group were four times more likely to be infected with an arbovirus p=0.003, 4.1 (95% CI 1.3-12.3). Significant arboviral activity was observed among outdoor workers(p=0.05) . Spatiotemporal analysis indicated arboviral activity in 23 of the 85 districts analysed.. Interpretation Our study shows that arbovirus activity peaks during the March-May rainy season and highlights the need for YFV mass vaccination to reduce the clinical burden of arboviruses transmitted within the region.

Abstract
PURPOSE The prevalence of under-diagnosis among individuals with obstructive sleep apnea (OSA) is alarming, and may be associated with perceptions regarding OSA. To facilitate future studies on OSA, this study validated the revised version of the Illness Perception Questionnaire (IPQ-R) for OSA in a general population. METHODS A random anonymous population-based telephone survey interviewed 580 adults aged ≥ 50 years in Hong Kong, who self-reported not having been told by doctors as having OSA, from February 5 to March 19, 2021. RESULTS The confirmatory factor analysis identified a modified 7-factor model (i.e., timeline chronic, consequence, personal control, treatment control, illness coherence, timeline cyclical, and emotional representation) that showed satisfactory model fit index and internal consistency. Nine items were removed from the original version because of low factor loadings. No floor and ceiling effects were observed. Convergent validity was supported by the positive associations between the consequence subscale with perceived negative outcomes of OSA and between the illness coherence subscale and perceived understanding of OSA symptoms. The participants tended to endorse the items of timeline chronic, treatment control, and illness coherence but not with those of emotional representations. The mean scores of the IPQ-R subscales differed by age and education level. CONCLUSION The modified IPQ-R of OSA showed acceptable psychometric properties. It is applicable to assessing illness perceptions of OSA in the Chinese general population aged ≥ 50 years not having received OSA diagnosis. The validated tool would support future studies and health practices related to OSA.

Abstract
Background and Aim The National Tuberculosis Elimination Program (NTEP) has been progressive in addressing the issues related to tuberculosis (TB) control in the country, with constant programmatic changes based on evidence available from operational research. Our objectives were 1. to assess the sociodemographic and clinical characteristics, and the treatment outcomes of patients on fixed-dose combination (FDC) daily regimen and 2. to assess the factors associated with unsuccessful treatment outcomes among patients with DS-TB. Materials and Methods A retrospective cohort study was conducted based on record review. The study population included all patients with drug-sensitive TB, registered and initiated on treatment under NTEP "new category" from January to June 2018 and under "previously treated category" from January to March 2018. Quantitative data downloaded from Nikshay in Excel format was imported. Results A total of 8301 patients with DS-TB registered under NTEP. Mean (standard deviation [SD]) age of DS-TB patients was 35.3 + 16.9 years, and 63.2% were in the age group of 15-44 years. Also, 60.1% were male, 2.5% were human immunodeficiency virus (HIV) positive, 65.3% were pulmonary TB cases, and 70.4% obtained treatment from public providers. Proportion of "successful" and "unsuccessful" outcomes was 87.9% and 12.1%, respectively, in the new treatment category and 78.3% and 21.7%, respectively, in the previously treated category. Among the patients classified under new category, the unsuccessful treatment outcome remained significantly high after adjustments with known confounders among patients aged 45-54 years (adjusted relative risks [aRR] 1.59, 95% confidence interval [CI] 1.31-1.93) and 55-64 years (aRR 1.67, 95% CI 1.36-2.05) compared to patients aged <15 years. Conclusion Unsuccessful treatment outcome was significantly high among patients aged 45-54 years. Various adherence mechanisms implemented can be evaluated for further upscaling and improving the program effectiveness.

Abstract
BACKGROUND In 1975, the mummified body of a female has been found in the Franciscan church in Basel, Switzerland. Molecular and genealogic analyses unveiled her identity as Anna Catharina Bischoff (ACB), a member of the upper class of post-reformed Basel, who died at the age of 68 years, in 1787. The reason behind her death is still a mystery, especially that toxicological analyses revealed high levels of mercury, a common treatment against infections at that time, in different body organs. The computed tomography (CT) and histological analysis showed bone lesions in the femurs, the rib cage, and the skull, which refers to a potential syphilis case. RESULTS Although we could not detect any molecular signs of the syphilis-causing pathogen Treponema pallidum subsp. pallidum, we realized high prevalence of a nontuberculous mycobacterium (NTM) species in brain tissue sample. The genome analysis of this NTM displayed richness of virulence genes and toxins, and similarity to other infectious NTM, known to infect immunocompromised patients. In addition, it displayed potential resistance to mercury compounds, which might indicate a selective advantage against the applied treatment. This suggests that ACB might have suffered from an atypical mycobacteriosis during her life, which could explain the mummy's bone lesion and high mercury concentrations. CONCLUSIONS The study of this mummy exemplifies the importance of employing differential diagnostic approaches in paleopathological analysis, by combining classical anthropological, radiological, histological, and toxicological observations with molecular analysis. It represents a proof-of-concept for the discovery of not-yet-described ancient pathogens in well-preserved specimens, using de novo metagenomic assembly.

Secondary infection with rapidly growing non-tuberculous mycobacteria is a rare complication of lipoid pneumonia. CASE PRESENTATION A 38-year-old man presented with fever, cough, sputum, chest tightness, and shortness of breath. He had a 2-year history of allergic rhinitis and used liquid paraffin-containing menthol nasal drops daily. A chest CT scan showed multiple patchy ground glass opacities with blurred borders in both lungs, which were located in the inner pulmonary field and distributed along the bronchi. His ambient air PO2 was 63 mmHg. The patient was diagnosed with ELP by CT-guided lung biopsy. The nasal drops were discontinued, and systemic glucocorticoids were administered. During treatment, the pulmonary lesions deteriorated, and bronchoalveolar lavage was performed during bronchoscopy. Additionally, Mycobacterium abscessus was detected in the lavage fluid. Upon detection of a secondary M. abscessus infection, glucocorticoids were gradually discontinued, and anti-M. abscessus treatment was implemented. The patient's symptoms rapidly ameliorated. After 11 months of anti-M. abscessus treatment, a repeat CT scan showed clear regression of the lung lesions. CONCLUSION Routine microbiological examination of samples, including sputum or alveolar lavage fluid, is necessary for patients with diagnosed or suspected ELP.

CLINICOECONOMICS AND OUTCOMES RESEARCH 2023; 15:181-193. [PMID: 36923468 PMCID: PMC10010142 DOI: 10.2147/ceor.s397766] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/19/2022] [Accepted: 03/03/2023] [Indexed: 03/12/2023] Open
Abstract
Background Most developing nations lag behind in maintaining their populations' health. These nations are characterized by under-financing, low health cost protection mechanisms for the poor, and lack of risk pooling and cost sharing methods. To tackle this challenge, Ethiopia proposed social health insurance in 2010 even though its implementation was delayed. Hence, the purpose of this study was to assess teachers' willingness to pay for the newly proposed social health insurance and its associated factors. Methods A cross-sectional study was conducted and a stratified sampling technique was used to select government and private schools. After data were collected using a semi-structured self-administered questionnaire, binary and multivariate logistic regressions were done to examine determinants of willingness to pay for social health insurance. Results Among participants who faced illness six months prior to the study, 85.7% reported that they paid "out of their pocket". About 59.2% and 54% of the teachers had a positive attitude and good knowledge toward health insurance schemes respectively. Of the total study respondents, 89.5% were willing to pay for the suggested insurance scheme. Forty eight percent of participants agreed to pay greater than or equal to 4% of their monthly salary. Willingness to pay was more likely among those who taught in secondary schools, had a positive attitude and good knowledge. Conclusion Nearly three fourths of the teachers showed willingness to pay for social health insurance. Participants with good knowledge, a positive attitude and from primary schools were more likely to be willing to pay for social health insurance. Equipping all public facilities' employees with necessary knowledge of social health insurance is essential to reduce catastrophic health care costs. Future researchers need to consider qualitative studies to support these findings.

Environ Health Prev Med 2023; 28:70. [PMID: 37967947 PMCID: PMC10654213 DOI: 10.1265/ehpm.23-00149] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/12/2023] [Accepted: 09/21/2023] [Indexed: 11/17/2023] Open
Abstract
BACKGROUND To analyze the prevalence and spatial-temporal characteristics of severe fever with thrombocytopenia syndrome (SFTS), clustering mode of transmission, and the serological dynamic detection results in multiple areas in Hefei from 2015 to 2021, and to provide the basis for SFTS prevention and control. METHOD Case data were obtained from the Chinese Disease Control and Prevention Information System. Information on the clustering outbreak was obtained from the outbreak investigation and disposal report. Population latent infection rate information was obtained from field sampling in multiple-incidence counties in 2016 and 2021 by multi-stage random sampling. Epi data3.2 and SPSS 16.0 softwares were used to perform a statistical analysis of the data on SFTS cases, and QGIS 3.26 software was used to draw the incidence map with township (street) as unit. RESULTS The an average annual reported incidence rate of SFTS in Hefei from 2015 to 2021 was 0.65/100,000, and the case fatality rate was 9.73%. The overall prevalence of SFTS epidemics in Hefei City showed a fluctuating upward trend from 2015 to 2021 (χ2trends = 103.353, P < 0.001). Chaohu City, Feixi County, Feidong County and Lujiang County ranked the top 4 in the city in terms of average annual incidence rate. The number of epidemic-involved towns (streets) kept increasing ((χ2trend = 47.640, P = 0.000)). Co-exposure to ticks accounted for the majority of clustered outbreaks and also human-to-human outbreaks. Population-based latent infection rate surveys were conducted in four SFTS multi-incidence counties, with 385 people surveyed in 2016 and 403 people surveyed in 2021, increasing the population-based latent infection rate from 6.75% to 10.91%, just as the incidence rate increased. CONCLUSIONS The incidence rate of SFTS in Hefei is obviously regional, with an expanding trend in the extent of the epidemic involved. Co-exposure to ticks accounted for the majority of clustered outbreaks and the latent infection rate cannot be ignored.

Abstract
Understanding the characteristics of people living with HIV who interrupt antiretroviral therapy (ART) is critical for designing client-centered services to ensure optimal outcomes. We assessed predictors of treatment interruption in 22 HIV clinics in Nigeria. We reviewed records of HIV-positive patients aged ≥15 years who started ART 1 January and 31 March 2019. We determined treatment status over 12 months as either active, or interrupted treatment (defined as interruption in treatment up to 28 days or longer). Potential predictors were assessed using Cox hazard regression models. Overall, 1185 patients were enrolled on ART, 829 (70%) were female, and median age was 32 years. Retention at 1, 3, 6, 9, and 12 months was 85%, 80%, 76%, 72%, and 68%, respectively. Predictors of treatment interruption were post-secondary education (p = 0.04), diagnosis through voluntary counseling and testing (p < 0.001), receiving care at low-volume facilities (p < 0.001), lack of access to a peer counselor (p < 0.001), and residing outside the clinic catchment area (p = 0.03). Treatment interruption was common but can be improved by focusing on lower volume health facilities, providing peer support especially to those with higher education, and client-centered HIV services for those who live further from clinics..

Investigating healthcare worker mobility and patient contacts within a UK hospital during the COVID-19 pandemic. COMMUNICATIONS MEDICINE 2022; 2:165. [PMID: 36564506 PMCID: PMC9782286 DOI: 10.1038/s43856-022-00229-x] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/09/2022] [Accepted: 12/08/2022] [Indexed: 12/24/2022] Open
Abstract
BACKGROUND Insights into behaviours relevant to the transmission of infections are extremely valuable for epidemiological investigations. Healthcare worker (HCW) mobility and patient contacts within the hospital can contribute to nosocomial outbreaks, yet data on these behaviours are often limited. METHODS Using electronic medical records and door access logs from a London teaching hospital during the COVID-19 pandemic, we derive indicators for HCW mobility and patient contacts at an aggregate level. We assess the spatial-temporal variations in HCW behaviour and, to demonstrate the utility of these behavioural markers, investigate changes in the indirect connectivity of patients (resulting from shared contacts with HCWs) and spatial connectivity of floors (owing to the movements of HCWs). RESULTS Fluctuations in HCW mobility and patient contacts were identified during the pandemic, with the most prominent changes in behaviour on floors handling the majority of COVID-19 patients. The connectivity between floors was disrupted by the pandemic and, while this stabilised after the first wave, the interconnectivity of COVID-19 and non-COVID-19 wards always featured. Daily rates of indirect contact between patients provided evidence for reactive staff cohorting in response to the number of COVID-19 patients in the hospital. CONCLUSIONS Routinely collected electronic records in the healthcare environment provide a means to rapidly assess and investigate behaviour change in the HCW population, and can support evidence based infection prevention and control activities. Integrating frameworks like ours into routine practice will empower decision makers and improve pandemic preparedness by providing tools to help curtail nosocomial outbreaks of communicable diseases.

Abstract
OBJECTIVE Mongolia is a sparsely populated country; however, almost fifty percent of the population lives in the capital city. Medical care services and exceptionally well-organized cervical cancer screening tests are limited in remote areas. To improve cervical cancer screening test coverage, we compared the interest between physicians taking samples and self-sampling among the attendees in this study. METHODS A total of 175 women participated in this study. The hundred twelve women visited the Gynecology ward, and the sixty-three women were provided with the cervical self-sampling test kit and filled out a questionnaire. Subsequently, the acceptability of physician taking and self-sampling were evaluated using a questionnaire. All specimens were processed using the TACAS LBC system, and the quality of samples was tested by cytology. RESULTS Regarding the acceptability of self-sampling, the selections for subsequent screening were 36% self-sampling and 64% gynecologist-sampling methods. The acceptability rates were higher in the remote areas than the urban areas. However, 64% of the participants lacked knowledge that the causative agent of cervical cancer is the human papillomavirus, and 66.9% mainly were sexually transmitted. In addition, 82.3% of the women surveyed were unaware that there was a vaccine to prevent cervical cancer, but 88.6% wanted to be vaccinated. Of most women, 44.4% chose self-sampling due to no embarrassment in the gynecological examination. The self-sampling preferences were dominant in the old age group (61.6%). The cytology satisfaction rate in physician-sampling (99.1%) was higher than in the self-sampling group (69.8%). CONCLUSION The Implementation of the self-sampling tool may be considered a primary screening. The self-sampling test can adopt into the early screening program and may increase the coverage of the screening program and improve the quality.
