Identification of metallo-β-lactamases and AmpC production among Escherichia coli strains isolated from hemodialysis patients with urinary tract infection

BACKGROUND

This study aimed to identify metallo-β-lactamases (MBLs) and AmpC β-lactamases-producing Escherichia coli isolates obtained from hemodialysis (HD) patients with urinary tract infections (UTI).

METHODS AND RESULTS

A total of 257 HD patients with UTI were included in this study, from which 47 E. coli isolates were collected. Antibiotic susceptibility was tested by disc diffusion method. MBLs and AmpC production were phenotypically detected by imipenem-ethylenediaminetetracetate and cefoxitin/boronic acid assays, respectively. The presence of MBLs and AmpC genes was examined by polymerase chain reaction (PCR). Fosfomycin and ampicillin were the most and the least effective antibiotics against E. coli isolates, respectively. Moreover, 61.7% (29/47) of E. coli isolates were multidrug-resistant with seven different antibiotypes. Antibiotype V (AMP-CIP-IMP-MEM-CPD-CRO-CTX-GEN-LEV-SXT-TOB) was the most prevalent profile. Besides, 24 (51.1%) isolates were simultaneously resistant to imipenem and meropenem. Phenotypic assay showed MBL production in 16 (66.7%) of the 24 carbapenem-resistant E. coli isolates. The distribution of MBL genes in carbapenem-resistant E. coli was as follows: blaIMP 18 (72%), blaVIM 7 (28%), and blaNDM 1 (4%). AmpC was detected in 61.7% (29/47) of the isolates using the phenotypic method. The presence of AmpC genes was confirmed by PCR in only 26 of 29 (86.7%) AmpC producers. The frequencies of blaDHA-1, blaACC, and blaCMY-2 were 6 (20.7%), 11 (37.9%), and 21 (72.4%), respectively.

CONCLUSIONS

The emergence of MBL and AmpC coproducing E. coli isolates calls for an urgent surveillance program for timely diagnosis and screening of these genes in our healthcare systems.

Trends in Prevalence of Tobacco Use by Sex and Socioeconomic Status in 22 Sub-Saharan African Countries, 2003-2019

IMPORTANCE

Tobacco companies have shifted their marketing and production to sub-Saharan African countries, which are in an early stage of the tobacco epidemic.

OBJECTIVE

To estimate changes in the prevalence of current tobacco use and socioeconomic inequalities among male and female participants from 22 sub-Saharan African countries from 2003 to 2019.

DESIGN, SETTING, AND PARTICIPANTS

Secondary data analyses were conducted of sequential Demographic and Health Surveys in 22 sub-Saharan African countries including male and female participants aged 15 to 49 years. The baseline surveys (2003-2011) and the most recent surveys (2011-2019) were pooled.

EXPOSURES

Household wealth index and highest educational level were the markers of inequality.

MAIN OUTCOMES AND MEASURES

Sex-specific absolute and relative changes in age-standardized prevalence of current tobacco use in each country and absolute and relative measures of inequality using pooled data.

RESULTS

The survey samples included 428 197 individuals (303 232 female participants [70.8%]; mean [SD] age, 28.6 [9.8] years) in the baseline surveys and 493 032 participants (348 490 female participants [70.7%]; mean [SD] age, 28.5 [9.4] years) in the most recent surveys. Both sexes were educated up to primary (35.7%) or secondary school (40.0%). The prevalence of current tobacco use among male participants ranged from 6.1% (95% CI, 5.2%-6.9%) in Ghana to 38.3% (95% CI, 35.8%-40.8%) in Lesotho in the baseline surveys and from 4.5% (95% CI, 3.7%-5.3%) in Ghana to 46.0% (95% CI, 43.2%-48.9%) in Lesotho during the most recent surveys. The decrease in prevalence ranged from 1.5% (Ghana) to 9.6% (Sierra Leone). The World Health Organization target of a 30% decrease in smoking was achieved among male participants in 8 countries: Rwanda, Nigeria, Ethiopia, Benin, Liberia, Tanzania, Burundi, and Cameroon. For female participants, the number of countries having a prevalence of smoking less than 1% increased from 9 in baseline surveys to 16 in the most recent surveys. The World Health Organization target of a 30% decrease in smoking was achieved among female participants in 15 countries: Cameroon, Namibia, Mozambique, Mali, Liberia, Nigeria, Burundi, Tanzania, Malawi, Kenya, Rwanda, Zimbabwe, Ethiopia, Burkina Faso, and Zambia. For both sexes, the prevalence of tobacco use and the decrease in prevalence of tobacco use were higher among less-educated individuals and individuals with low income. In both groups, the magnitude of inequalities consistently decreased, and its direction remained the same. Absolute inequalities were 3-fold higher among male participants, while relative inequalities were nearly 2-fold higher among female participants.

CONCLUSIONS AND RELEVANCE

Contrary to a projected increase, tobacco use decreased in most sub-Saharan African countries. Persisting socioeconomic inequalities warrant the stricter implementation of tobacco control measures to reach less-educated individuals and individuals with low income.

Comparison of Clinical Characteristics and Outcomes of Younger and Elderly Patients with Severe COVID-19 in Korea: A Retrospective Multicenter Study

Old age is associated with disease severity and poor prognosis among coronavirus disease 2019 (COVID-19) cases; however, characteristics of elderly patients with severe COVID-19 are limited. We aimed to assess the clinical characteristics and outcomes of patients hospitalized with severe COVID-19 at tertiary care centers in South Korea. This retrospective multicenter study included patients with severe COVID-19 who were admitted at seven hospitals in South Korea from 2 February 2020 to 28 February 2021. The Cox regression analyses were performed to assess factors associated with the in-hospital mortality. Of 488 patients with severe COVID-19, 318 (65.2%) were elderly (≥65 years). The older patient group had more underlying diseases and a higher severity score than the younger patient group. The older patient group had a higher in-hospital mortality rate than the younger patient group (25.5% versus 4.7%, p-value < 0.001). The in-hospital mortality risk factors among patients with severe COVID-19 included age, acute physiology and chronic health evaluation II score, presence of diabetes and chronic obstructive lung disease, high white blood cell count, low neutrophil-lymphocyte ratio and platelet count, do-not-resuscitate order, and treatment with invasive mechanical ventilation. In addition to old age, disease severity and examination results must be considered in treatment decision-making.

Seroprevalence of Anti-SARS-CoV-2 Antibodies among Municipal Staff in the Municipality of Prishtina

BACKGROUND

Some studies have assessed the seroprevalence of anti-SARS-CoV-2 antibodies in different populations. Very few studies have explored seroprevalence in municipal workers, an important and potentially high-risk population. This study aims to determine the prevalence of anti-SARS-CoV-2 antibodies in municipal workers, with the additional examination of the association of prevalence with various demographic, health-related, and epidemiological factors.

METHODS

We surveyed and tested for seroprevalence 418 public servants from the municipality of Prishtina, the capital of Kosovo. The primary prespecified outcome was the seroprevalence of anti-SARS-CoV-2 antibodies, IgG, and IgM. Additional outcomes were crude and adjusted odds ratios of seroprevalence by different factors.

RESULTS

21.1% of municipal workers tested positive for either IgM or IgG. Of these, 9.6% were positive for IgM and 19.4% for IgG. Data showed high levels of adherence to protective measures, e.g., social distancing in the office, but calculation of ORs did not show a significant difference between those reporting adherence to such measures and those reporting nonadherence. Of other examined factors, significantly lower odds were observed for smokers (0.52, 95% CI 0.28, 0.97), while municipal workers with infected family members had elevated odds of seropositivity according to both crude (2.19, 95% CI 1.34, 3.59) and adjusted (2.00, 95% CI 1.17, 3.41) ORs.

CONCLUSIONS

Most answers from public servants demonstrated compliance to social-distancing policies in the workplace, but analysis of crude and adjusted odds ratios did not suggest a significant effect between municipal workers who followed these guidelines and those who did not. Results from this study help Kosovo policy makers in understanding the level of prevalence of COVID-19 in municipal workers and the effect of different factors on such prevalence. Results from the study could inform future decisions on the design and application of protective measures for municipal workers. Our findings should encourage further research to assess the extent of the spread of COVID-19 to other essential workers in Kosovo, including retail workers.

Vitamin D Deficiency in Patients with Diabetes in French Guiana: Epidemiology and Relation with Microvascular and Macrovascular Complications

Vitamin D (VD) insufficiency is common among patients with diabetes in French Guiana. The study aimed to evaluate the prevalence of VD deficiency in the different type of diabetes encountered and to analyze the relationship between VD deficiency and diabetes complications. Methods: An observational study was conducted between May 2019 and May 2020 in French Guiana, based on data from the CODIAM study (Diabetes Cohort in French Amazonia), describing the characteristics of patients with diabetes mellitus. Among 600 patients enrolled with diabetes, 361 had an available VD assay. Results: The mean 25(OH)VD (hydroxycalciferol) level was 27.9 ng/mL. The level of VD was inversely proportional to the HbA1c (glycated hemoglobin) level. Patients with angina pectoris had a greater proportion of deficiencies VD < 20 ng/mL than those without angina. By contrast, patients with retinopathy had higher vitamin D concentrations than those without retinopathy. There was no association between vitamin D and arteriopathy, stroke, nephropathy and polyneuropathy. VD deficiency was more frequent in women, and in patients with a high school education. Conclusion: The prevalence of VD deficiency was high in patients with diabetes in French Guiana, emphasizing the importance of VD supplementation.

From Tobacco Cigarettes to Electronic Cigarettes: The Two Sides of a Nicotine Coin

Tobacco smoking-related diseases, including cardiovascular disease, pulmonary disease, stroke, and cancer in multiple organ sites, are the leading causes of preventable death, worldwide. Youth electronic cigarette use (vaping) is an evolving public health problem in the United States and around the world. Many of the same toxicants and carcinogens present in tobacco smoke are also found in electronic cigarette vapor, although mostly at substantially lower levels. The reduced concentrations of these chemicals in electronic cigarette vapor may imply lower health risk; however, they cannot equate to no risk. To date, the long-term health consequences of vaping are largely unknown. This "Perspective" provides a concise chronology of events leading up to an unprecedented global challenge, namely the convergence of global tobacco epidemic and youth vaping epidemic. Current state of knowledge, outstanding questions in the field, present challenges, and future directions in research are highlighted. The existing data show a continued and dynamic evolution of the converged epidemics. The goal should be to prevent youth vaping while improving smoking cessation strategies. In smokers who are unable or unwilling to quit smoking, the objective should be to provide "provably" safe or less-harmful alternatives, which should "completely" or "substantially" substitute tobacco cigarettes.

Monitoring Study Participants and Implementation with Phone Calls to Support Hypertension Control During the COVID-19 Pandemic: The Case of a Multicomponent Intervention Trial in Guatemala

Background

The COVID-19 pandemic presents a challenge to health care for patients with chronic diseases, especially hypertension, because of the important association and increased risk of these patients with a severe presentation of COVID-19 disease. The Guatemalan Ministry of Health has been implementing a multi-component program aimed at improving hypertension control in rural communities since 2019 as a part of an intervention research cluster randomized trial. When the first cases of COVID-19 were reported (March 13, 2020) in Guatemala, our study paused all study field activities, and began monitoring participants through phone calls. The objective of this paper is to describe the approach used to monitor study participants during the COVID-19 pandemic and compare data obtained during phone calls for intervention and control group participants.

Methods

We developed a cross-sectional study within the HyTREC (Hypertension Outcomes for T4 Research within Lower Middle-Income Countries) project 'Multicomponent Intervention to Improve Hypertension Control in Central America: Guatemala' in which phone calls were made to participants from both intervention and control groups to monitor measures important to the study: delivery of antihypertensive medications in both groups, receipt of coaching sessions and use of a home blood pressure monitor by intervention group participants, as well as reasons that they were not implemented.

Results

Regarding the delivery of antihypertensive drugs by the MoH to participants, those in the intervention group had a higher level of medication delivery (73%) than the control group (51%), p<0.001. Of the total participants in the intervention group, 62% had received at least one health coaching session in the previous three months and 81% used a digital home blood pressure monitor at least twice a week. Intervention activities were lower than expected due to restricted public transportation on top of decreased availability of health providers.

Conclusion

In Guatemala, specifically in rural settings, access to antihypertensive medications and health services during pandemic times was impaired and less than expected, even after accounting for the program's implementation activities and actions.

Knowledge and transmission risk awareness of tuberculosis among the pilgrims attending a religious mass gathering in India: a cross-sectional study

Background

Tuberculosis infection accounts for more annual deaths than any other single infectious disease, except the Corona Virus infection. It is a significant global issue and India is one of the most affected countries. Religious mass gatherings congregate millions of pilgrims at one place. Over-crowding is a high-risk factor for the transmission of tuberculosis. Knowledge and awareness of the disease are proven prerequisites for the spread-prevention and early diagnosis of tuberculosis. The present study was designed to explore the knowledge of tuberculosis and awareness of disease transmission risk among pilgrims attending a religious mass gathering, the Kumbh Mela (2016) in Ujjain, India.

Methods

Self-reported data on the pilgrims’ tuberculosis-knowledge were collected using a cross-sectional study design. A contextual, pre-tested questionnaire was used, using the convenience sampling method. In addition to the anonymous descriptive analyses, a composite knowledge-score was developed to enable comparisons between demographic groups.

Results

In total, 1665 pilgrims participated in the study with 38.8 years of mean age and 59% literacy rate. The most recognized symptoms of tuberculosis were “Cough for more than 15 days with sputum” (94%) and “Blood in sputum” (81%). Most participants knew that tuberculosis is an infectious disease (93%) and not hereditary (91%). Additionally, 84% considered it is a potentially lethal disease that requires extensive treatment. However, vaccine awareness was poor (4%). “Direct contact with tuberculosis patient” (78%) and “To be in a crowded area” (4%) were considered as the most important risk factors for tuberculosis transmission. For the composite knowledge-score, a significantly higher mean score was seen among those with at least ten years of schooling compared with illiterates (p <  0.001). Occupation and residency also affected the mean score.

Conclusion

Most pilgrims attending the Kumbh Mela had basic knowledge of the characteristics of tuberculosis, but some important knowledge gaps concerning the transmission risks associated with crowded situations existed. These gaps need to be addressed in future policies to enable safer mass gatherings and to end the TB epidemic, globally.

Predictors of Adherence to Smoking Cessation Medications among Current and Ex-Smokers in Australia: Findings from a National Cross-Sectional Survey

Background: Adherence to smoking cessation medications (SCMs) improve the rate of successful quitting. This study aimed to evaluate the level of adherence to SCMs and associated factors among smokers and ex-smokers in Australia. Method: A cross-sectional study using an online survey was conducted in Australia. Descriptive statistics were used to present the overall characteristics of participants. Cross-tabulation with Pearson’s chi-square test was performed to evaluate the possible associations between factors. To explore barriers and facilitators of adherence to SCMs, logistic regressions were conducted. Results: Among 201 participants, 57 (28.4%) were found to be adherent to SCMs. The odds of being adherent were found to be higher among participants with good social support (AOR = 3.28, 95% CI of 2.30–6.27). Participants who did not experience anxiety symptoms had higher odds of being adherent to SCMs as compared to smokers who had anxiety symptoms (AOR = 4.41, 95% CI of 3.64–14.68). Having previous experience of using SCMs improved adherence four-fold (AOR = 3.87, 95% CI of 1.11–13.44). Level of nicotine dependence showed a direct association with adherence (AOR = 3.53, 95% CI of 1.40–8.95). Not relapsing while on the medications improved adherence (AOR = 2.88, 95% CI of 1.21–6.88). Conclusion: In a study of smokers and ex-smokers in Australia, the self-reported level of adherence to SCMs was found to be low. Adherence was associated with social, psychological, and medication-related factors. Smoking cessation interventions are recommended to include strategies that can address medication adherence.

Global burden of COPD attributable to ambient PM2.5 in 204 countries and territories, 1990 to 2019: A systematic analysis for the Global Burden of Disease Study 2019

The global spatiotemporal pattern of the COPD burden attributable to ambient PM2.5 is unknown in the context of the continuing increase in exposure to ambient PM2.5. Data on COPD burden attributable to ambient PM2.5 from 1990 to 2019 were retrieved from the Global Burden of Disease Study 2019. Cases and age-standardized rates of COPD mortality (ASMR) and disability-adjusted life years (ASDR) were estimated by age, sex, region, and country. The estimated annual percentage change (EAPC) was calculated to quantify the secular trends of ASMR and ASDR from 1990 to 2019. Globally, the number of COPD deaths and DALYs attributable to ambient PM2.5 both increased by over 90% from 1990 to 2019, but ASMR and ASDR both slightly decreased, with EAPC of -0.58 (95% CI: -0.72, -0.44) and -0.40 (95% CI: -0.51, -0.29), respectively. Most COPD deaths and DALYs attributable to PM2.5 occurred in the middle sociodemographic index (SDI) region, but the fastest growth of ASMR and ASDR occurred in the low SDI region, with EAPCs of 2.41 (95% CI: 2.23, 2.59) and 2.34 (95% CI: 2.16, 2.52), respectively. East Asia and South Asia were the high-risk areas of COPD deaths and DALYs attributable to PM2.5, among which China and India were the countries with the heaviest burden. COPD deaths and DALYs attributable to PM2.5 mainly occurred in individuals 70-89 years old and 60-84 years old, respectively. The age-specific rates of mortality and DALYs had a rapid increase in low and low-middle SDI regions from 1990 to 2019. The ASMR or ASDR had a reverse V-shaped relationship with SDI. In summary, the ambient PM2.5-attributable COPD burden is socioeconomic- and age-dependent, and it mediates the heterogeneity of spatial and temporal distribution. Low- and middle-income countries endure the highest ambient PM2.5-attributable COPD burden due to the high exposure to PM2.5 and poor availability and affordability of medicines and diagnostic tests.

Socio-demographic variables related to self-esteem, psychological stress and health-related quality of life among older adults: A cross-sectional study in Kavrepalanchowk district of Nepal

Objective

The study aimed to assess how socio-demographic variables related to self-esteem, psychological stress and health-related quality of life among older adults in Nepal.

Method

A cross-sectional community-based study was conducted in the Kavrepalanchowk district of Nepal. A two-stage cluster sampling technique was used for selecting the study areas, and 239 older adult participants were selected randomly from the clusters. The interview technique was applied to gather data using validated tools. The tools used in the study were Rosenberg self-esteem scale, Perceived Stress Scale and WHOQOL-BREF scale. Scoring was carried out for self-esteem, perceived stress and WHOQOL-BREF in accordance with the procedures. Data were analyzed using descriptive statistics and inferential statistics (Chi-square, independent t-test and one-way analysis of variance).

Results

Among the total participants, 27.2% were 60-64 years old and more than two-thirds (69.9%) were male. The majority of participants were married (65.5%) and cannot read and write (60.7%). Half of the older adults (49.8%) were living with their partners. Self-esteem was high among the age group 70-74 years (24.80 ± 3.01), and psychological stress was high among the age group 60-64 years (17.23 ± 2.93) within the older adults. Furthermore, the mean score for the social relationship domain and physical health domain of health-related quality of life were 12.0 and 11.9, respectively. Comparing the domains of physical health, psychological health and social relationship with age and education level were statistically significant.

Conclusion

Self-esteem was lower among older male adults aged 60-64 years and those who attended secondary level education. An increase in participants' age increases the psychological stress and decreases the psychological domain of health-related quality of life.

Designing Better Exposure Notification Apps: The Role of Persuasive Design

BACKGROUND

Digital contact tracing apps have been deployed worldwide to limit the spread of COVID-19 during this pandemic and to facilitate the lifting of public health restrictions. However, due to privacy-, trust-, and design-related issues, the apps are yet to be widely adopted. This calls for an intervention to enable a critical mass of users to adopt them.

OBJECTIVE

The aim of this paper is to provide guidelines to design contact tracing apps as persuasive technologies to make them more appealing and effective.

METHODS

We identified the limitations of the current contact tracing apps on the market using the Government of Canada's official exposure notification app (COVID Alert) as a case study. Particularly, we identified three interfaces in the COVID Alert app where the design can be improved. The interfaces include the no exposure status interface, exposure interface, and diagnosis report interface. We propose persuasive technology design guidelines to make them more motivational and effective in eliciting the desired behavior change.

RESULTS

Apart from trust and privacy concerns, we identified the minimalist and nonmotivational design of exposure notification apps as the key design-related factors that contribute to the current low uptake. We proposed persuasive strategies such as self-monitoring of daily contacts and exposure time to make the no exposure and exposure interfaces visually appealing and motivational. Moreover, we proposed social learning, praise, and reward to increase the diagnosis report interface's effectiveness.

CONCLUSIONS

We demonstrated that exposure notification apps can be designed as persuasive technologies by incorporating key persuasive features, which have the potential to improve uptake, use, COVID-19 diagnosis reporting, and compliance with social distancing guidelines.

Developing a Complex Understanding of Physical Activity in Cardiometabolic Disease from Low-to-Middle-Income Countries-A Qualitative Systematic Review with Meta-Synthesis

Physical activity behaviour is complex, particularly in low-resource settings, while existing behavioural models of physical activity behaviour are often linear and deterministic. The objective of this review was to (i) synthesise the wide scope of factors that affect physical activity and thereby (ii) underpin the complexity of physical activity in low-resource settings through a qualitative meta-synthesis of studies conducted among patients with cardiometabolic disease living in low-to-middle income countries (LMIC). A total of 41 studies were included from 1200 unique citations (up to 15 March 2021). Using a hybrid form of content analysis, unique factors (n = 208) that inform physical activity were identified, and, through qualitative meta-synthesis, these codes were aggregated into categories (n = 61) and synthesised findings (n = 26). An additional five findings were added through deliberation within the review team. Collectively, the 31 synthesised findings highlight the complexity of physical activity behaviour, and the connectedness between person, social context, healthcare system, and built and natural environment. Existing behavioural and ecological models are inadequate in fully understanding physical activity participation in patients with cardiometabolic disease living in LMIC. Future research, building on complexity science and systems thinking, is needed to identify key mechanisms of action applicable to the local context.

Impact of COVID-19 Pandemic on Childhood Immunization in a Tertiary Health-Care Center

Background:

After the emergence of COVID-19 pandemic, health facilities nationwide became the battleground for COVID-19. Many hospitals are designated as COVID-19 hospitals and various measures taken by the government to contain the spread of infection have disrupted the provision of routine health-care services including immunization. The aim of this study is to describe the impact of COVID-19 pandemic on immunization in a tertiary level health-care facility.

Materials and Methodology:

Data of children vaccinated as per the Universal immunization program (UIP) schedule were retrieved from immunizations records for a 7 month (January to July) period for the years 2019 and 2020. The trends of vaccination during COVID-19 pandemic are studied and are compared with the date matched data of the previous year.

Results:

There was a significant drop in the vaccine counts after emergence of COVID-19 pandemic. Maximum drop (−87%) was seen during the month of April (76.52% ± 43.62% vs. 16.95% ± 42.55%; P < 0.001) followed by May and June when it was −67% and −33%, respectively.

Conclusion:

COVID-19 pandemic has created the gaps in immunization which requires immediate attention. Further failure in sustaining the vaccination services and weak catch-up plans can lead to the emergence of vaccine-preventable diseases which may result in increased childhood morbidity and mortality.

COVID-19 pandemic and antimicrobial resistance in developing countries

A wide range of antimicrobial agents were touted as potential remedies during the COVID-19 pandemic. While both developed and developing countries have recorded an increase in the use of antimicrobial drugs, use and misuse have occurred to a far greater degree in developing countries. This can have deleterious consequences on antimicrobial resistance, especially when various developing countries have already reported the emergence of various drug-resistant organisms even before the pandemic. Telemedicine services, societal and cultural pressures, and bacterial co-infections can predispose to overwhelming antimicrobial prescriptions. The emergence of new multidrug resistance species is a major concern for the developing world especially since health services are already overburdened and lack the diagnostic capabilities and basic amenities for infection prevention and control. This can lead to outbreaks and the rampant spread of such microorganisms. Improper waste management and disposal from hospitals and communities establish freshwater runoffs as hubs of various microorganisms that can predispose to the rise of multidrug-resistant species. Microplastics' ability to act as vectors for antibiotic-resistant organisms is also particularly concerning for lower-middle-income countries. In this review, we aim to study the impact of antimicrobial use during the COVID-19 pandemic and antimicrobial resistance in lower middle-income countries, by understanding various determinants of resistance unique to the developing world and exploring solutions to combat the problem.

Pandemic Preparedness

Pandemic preparedness is a key function of any health care facility. Activities pertaining to pandemic preparedness should be developed and maintained within a broader emergency management plan. The use of a Hospital Incident Command System can centralize coordination of the response and facilitate internal and external communication. This review addresses several components of pandemic preparedness, including incident management, health care personnel safety, strategies to support ongoing clinical activities, and organizational communication during a pandemic. Preparations addressing potential ethical challenges and the psychological impact associated with pandemic response are also reviewed.

Taking care of the ordinary in extraordinary times-delayed routine care means more morbidity and pre-mature mortality

Individuals with chronic diseases are more susceptible to its grave complications and negative outcomes if infected by COVID-19. Furthermore, mandatory isolation and cancellations of routine healthcare services led to the disruption of the screening and management plans for chronic diseases. Fear of attending health services as well as disruptions to public transport are other factors increasing health risks among persons with chronic conditions during the pandemic. Ensuring access to universal healthcare services, increasing use of digital services, targeted interventions to risk groups are examples of measures that need to be taken when reviewing health systems preparedness for future pandemics and other disasters.

Does Prolonged Infusion Time Really Improve the Efficacy of Meropenem Therapy? A Prospective Study in Critically Ill Patients

Introduction

Meropenem is a carbapenem antibiotic, which has demonstrated excellent antimicrobial activity against gram-negative clinical isolates. It is also commonly used in critically ill patients. This study aimed to determine the pharmacokinetics/pharmacodynamics of meropenem in critically ill patients and whether prolonged injection duration is really beneficial to meropenem therapy.

Methods

We included 209 samples in 64 patients in this prospective study. PPK analysis and Monte Carlo dosing simulations were developed using Phoenix.

Results

A two-compartment model described the data adequately. Clearance (CL), volume (V), clearance of peripheral compartment (CL₂), and volume of peripheral compartment (V₂) were 6.15 l/h, 2.83 l/h, 17.40 l, and 17.48 l, respectively. Creatinine clearance and uric acid were significant covariates. Patients with creatinine clearance ≤ 60 ml/min and uric acid > 400 μmol/l could achieve the target > 90% under the minimum inhibitory concentration (MIC) of 8 mg/l, even with the administration dose of 500 mg/8 h with a 2-h infusion. Prolonging the infusion time significantly improved the therapeutic effect when MIC < 4. However, for the pharmacodynamic (PD) effects of 100% fT > MIC and 100% fT > 4 MIC, no significant statistical difference was observed in critically ill patients.

Conclusions

Critically ill patients with lower creatinine clearance and higher uric acid levels tended to need a lower dosage of meropenem. Prolonged infusion time was not always beneficial for those who needed a higher therapeutic target (100% fT > MIC, 100% fT > 4 MIC) or with MIC > 4 mg/l. Increasing dose or alternative therapeutic strategies may be required for critically ill patients with drug-resistant or severe infections. The study is of great significance to guide the rational use of meropenem in critically ill patients.

Trial Registration

The trial was registered in the China Clinical Trial (ChiCTR1900020672). Registered on 12 January 2019.

Supplementary Information

The online version contains supplementary material available at 10.1007/s40121-021-00551-2.

Meropenem is commonly used empirically or targeted in critically ill patients for bacterial infection. Many studies have reported that prolonged infusion time can improve the efficacy of meropenem therapy. However, we are skeptical about that. Meanwhile, prolonged injections can sometimes cause mobility problems for patients. A quantitative method is used to evaluate meropenem use. It is called the population pharmacokinetic model or pharmacodynamic study. Using this method, we found two significant influencing factors of meropenem metabolism: creatinine clearance and uric acid level. It is likely that patients with a lower level of creatinine clearance and a high uric acid level tend to require lower dosages of meropenem. As for the effect of infusion time, Monte Carlo simulation was used, which can do 3000 simulations on an individual. The result was complex. We found infusion time was beneficial only when bacteria were sensitive to meropenem. The evidence suggests that prolonged injection duration sometimes does not significantly improve the outcome of antimicrobial therapy.

Understanding the Social Determinants of Mental Health of Undergraduate Students in Bangladesh: Interview Study

Background

The undergraduate student population has been actively studied in digital mental health research. However, the existing literature primarily focuses on students from high-income nations, and undergraduates from limited-income nations remain understudied.

Objective

This study aims to identify the broader social determinants of mental health among undergraduate students in Bangladesh, a limited-income nation in South Asia; study the manifestation of these determinants in their day-to-day lives; and explore the feasibility of self-monitoring tools in helping them identify the specific factors or relationships that affect their mental health.

Methods

We conducted a 21-day study with 38 undergraduate students from 7 universities in Bangladesh. We conducted 2 semistructured interviews: one prestudy and one poststudy. During the 21-day study, participants used an Android app to self-report and self-monitor their mood after each phone conversation. The app prompted participants to report their mood after each phone conversation and provided graphs and charts so that the participants could independently review their mood and conversation patterns.

Results

Our results show that academics, family, job and economic condition, romantic relationship, and religion are the major social determinants of mental health among undergraduate students in Bangladesh. Our app helped the participants pinpoint the specific issues related to these factors, as the participants could review the pattern of their moods and emotions from past conversation history. Although our app does not provide any explicit recommendation, the participants took certain steps on their own to improve their mental health (eg, reduced the frequency of communication with certain persons).

Conclusions

Although some of the factors (eg, academics) were reported in previous studies conducted in the Global North, this paper sheds light on some new issues (eg, extended family problems and religion) that are specific to the context of the Global South. Overall, the findings from this study would provide better insights for researchers to design better solutions to help the younger population from this part of the world.

Mobile Phones: Vital Addiction or Lethal Addiction? Mobile Phone Usage Patterns and Assessment of Mobile Addiction among Undergraduate Medical Students in Telangana, India

Background

Increased mobile phone usage among undergraduate medical students causes a detrimental effect on their health. The main focus of this study is to determine the pattern of mobile phone usage among undergraduate medical students in Hyderabad, India, and the detrimental effect on their health due to excess mobile use.

Materials and Methods

A cross-sectional study was conducted among undergraduate medical students from various medical colleges in Hyderabad, India, from September 2020 to January 2021. Data were collected from 626 respondents using a semistructured, pretested questionnaire. Smartphone Addiction Scale-Short Version (SAS-SV) was used to assess the risk of smartphone addiction. Microsoft Excel and SAS were employed to analyze the data. Associations were examined using Fisher's exact test.

Results

100% of the respondents were using mobiles, with 83.2% spending more than 4 hours on them. Only 22% reported that no mobile use during classes. Half (51.6%) admitted to keeping their mobiles close by while sleeping. 84.3% used social networking apps via their mobiles. Common symptoms arising from prolonged mobile usage included eye strain (67.9%), blurred vision (31.4%), and numbness or tingling in palms (30.9%). 52.70% of the respondents were at high risk of mobile addiction according to SAS-SV. Screen time more than 4 hours was associated with high risk of mobile addiction (p < 0.0001). Significant association was found between high risk of mobile addiction and eye strain (p < 0.0001), blurry vision (p=0.0115), numbness/tingling in palms (p < 0.0001), and heat/tingling in the auditory area (p < 0.0001).

Conclusion

The study shows the alarming rate of risk of smartphone addiction among medical students. Students can be encouraged to assess their mobile addiction status and become aware of the issue. More research may be performed to develop standardized tools for early identification of mobile addiction and appropriate therapies for its rectification.

Recent updates on bioactive properties of linalool

Natural products, including essential oils and their components, have been used for their bioactivities. Linalool (2,6-dimethyl-2,7-octadien-6-ol) is an aromatic monoterpene alcohol that is widely found in essential oils and is broadly used in perfumes, cosmetics, household cleaners and food additives. This review covers the sources, physicochemical properties, application, synthesis and bioactivities of linalool. The present study focuses on the bioactive properties of linalool, including anticancer, antimicrobial, neuroprotective, anxiolytic, antidepressant, anti-stress, hepatoprotective, renal protective, and lung protective activity and the underlying mechanisms. Besides this, the therapeutic potential of linalool and the prospect of encapsulating linalool are also discussed. Linalool can induce apoptosis of cancer cells via oxidative stress, and at the same time protects normal cells. Linalool exerts antimicrobial effects through disruption of cell membranes. The protective effects of linalool to the liver, kidney and lung are owing to its anti-inflammatory activity. On account of its protective effects and low toxicity, linalool can be used as an adjuvant of anticancer drugs or antibiotics. Therefore, linalool has a great potential to be applied as a natural and safe alternative therapeutic.

Investigating the effective factors of using mHealth apps for monitoring COVID-19 symptoms and contact tracing: A survey among Iranian citizens

BACKGROUND AND OBJECTIVES

The use of mHealth applications depends on cognitive and social factors of individuals in different nations. This study aimed to identify the factors influencing the use of mHealth applications for both "contact-tracing" and "symptom-monitoring" of COVID-19 among Iranian citizens.

METHODS

A cross-sectional study with an online survey was conducted among Iranian citizens. Correlation calculation and multiple linear regression analysis were performed on the studied variables to find the effective factors.

RESULTS

A total of 1031 Iranian citizens over the age of 18 participated in this survey. A large percentage of the participants wanted to use the mHealth app to trace contacts of COVID-19 (74.5%) and the mHealth app to identify and monitor COVID-19 symptoms (74.0%). Gender, age, level of education, attitude towards technology, and fear of COVID-19 were among the factors that influenced the intention to use these two apps. The top reasons for using these apps were: "to keep myself and my family safe", "to control the spread of the coronavirus in general", and "to cooperate with healthcare professionals". The reasons given for not using these two apps were related to the issues of "security and privacy" and "doubt in efficiency and usefulness" of them.

CONCLUSIONS

The study showed that many participants in this survey were interested in using the COVID-19 apps. Policies, regulations and procedures are needed to protect the privacy of individuals by ensuring data governance. Further investigation with a larger sample is suggested to generalize these results.

A systematic review and meta-analysis of non-adherence to anti-diabetic medication: Evidence from low- and middle-income countries

BACKGROUND

Non-adherence to anti-diabetic medication is an important cause of uncontrolled blood glucose that leads to complications of diabetes. However, there is a lack of evidence on the burden of and factors associated with non-adherence to anti-diabetic medication among individuals living with diabetes in low-and middle-income countries (LMICs).

OBJECTIVES

This systematic literature review and meta-analytic synthesis aims to estimate non-adherence to anti-diabetic medication reported among individuals in LMICs and explores factors affecting non-adherence.

METHODS

We systematically searched MEDLINE and Embase to identify studies investigating non-adherence to anti-diabetic medications published from January 2000 to May 2020. Two authors carried out study selection, screening, and data extraction independently. Cross-sectional studies that had been conducted among individuals with diabetes in LMICs were eligible for the selection process. Critical appraisal of the included studies was carried out using the Newcastle Ottawa Scale. Meta-analysis was carried out using Stata 14.2. Random effects model was used to compute the pooled proportion at a 95% confidence interval (CI).

RESULTS

Forty-three studies met the inclusion criteria, of which 13 studies were used in meta-analysis. The pooled proportion of non-adherence to anti-diabetic medications using the eight-item Morisky Medication Adherence Scale (MMAS-8) was 43.4% (95% CI: 17.5-69.4; P < 0.001) and 29.1% (95% CI: 19.8-38.4; P < 0.001) when using the cut-off at 80 or 90%. The pooled proportion of non-adherence was 29.5% (95% CI: 25.5-33.5; P = .098) when using the four-item Morisky Medication Adherence Scale (MMAS-4). Using the World Health Organization (WHO) five dimensions of medication adherence framework, the factors contributing to non-adherence were varied, including disease factors, therapy-related factors, healthcare system factor, patient-centred factors, and socio-economic factors.

CONCLUSIONS

Non-adherence to anti-diabetic medication remains an ongoing challenge in LMICs and several factors operating at different levels were cited as reasons. Comprehensive intervention strategies are urgently needed to address these factors in effectively tackling medication non-adherence in LMICs.

Availability of Key Essential Medicines in Public Health Facilities of South Indian Union Territory: One of the Crucial Components of Universal Health Coverage

Introduction The supply of essential medicines is one of the vital components of primary health care. One of the important objectives of Indian health policy is to provide all the essential medicines at an affordable cost for the public. The performance of healthcare facilities is directly affected by the supply of essential medicines. This study was conducted to check the availability of key essential medicines in selected public healthcare facilities of the South Indian Union Territory. Methods A snapshot survey was conducted between March 2019 and February 2020 in 10 selected public health facilities to assess the availability of 50 key essential medicines. Percentage availability for all surveyed medicines for the individual facility as well as percentage availability of individual medicines in all surveyed health facilities was calculated. Results Percentage availability of 50 key essential medicines in 10 surveyed public health facilities was found in a range of 66 to 80%. Out of 50 medicines, 26 (52%) medicines were available in more than 80% of health facilities while six (12%) medicines were available in less than 30% of surveyed facilities. Conclusion This study reported the high availability of essential medicines in public health facilities as compared to similar studies done in other parts of India but the availability of some essential medicines was found sub-optimal and needs to be improved.

Zinc as a Drug for Wilson's Disease, Non-Alcoholic Liver Disease and COVID-19-Related Liver Injury

Zinc is the second most abundant trace element in the human body, and it plays a fundamental role in human physiology, being an integral component of hundreds of enzymes and transcription factors. The discovery that zinc atoms may compete with copper for their absorption in the gastrointestinal tract let to introduce zinc in the therapy of Wilson's disease, a congenital disorder of copper metabolism characterized by a systemic copper storage. Nowadays, zinc salts are considered one of the best therapeutic approach in patients affected by Wilson's disease. On the basis of the similarities, at histological level, between Wilson's disease and non-alcoholic liver disease, zinc has been successfully introduced in the therapy of non-alcoholic liver disease, with positive effects both on insulin resistance and oxidative stress. Recently, zinc deficiency has been indicated as a possible factor responsible for the susceptibility of elderly patients to undergo infection by SARS-CoV-2, the coronavirus responsible for the COVID-19 pandemic. Here, we present the data correlating zinc deficiency with the insurgence and progression of Covid-19 with low zinc levels associated with severe disease states. Finally, the relevance of zinc supplementation in aged people at risk for SARS-CoV-2 is underlined, with the aim that the zinc-based drug, classically used in the treatment of copper overload, might be recorded as one of the tools reducing the mortality of COVID-19, particularly in elderly people.

Epidemiological Characteristics of Pancreatic Cancer in China From 1990 to 2019

Background

Pancreatic cancer is an aggressive cancer and is predicted to become the second leading cause of cancer-related deaths in China. To understand the epidemic trend of pancreatic cancer and formulate targeted preventive measures, it is important to analyze the incidence and mortality of pancreatic cancer.

Methods

The incidence and mortality data of pancreatic cancer in China were obtained from Global Burden of Disease (GBD) data. We used joinpoint regression analysis to calculate the magnitude and direction of trends, and the age-period-cohort method to analyze the effects of chronological age, time period, and birth cohort.

Results

The age-standardized rates (ASRs) for both incidence and mortality of pancreatic cancer increased from 1990 to 2019, and were higher in males than females. The incidence and mortality rates have increased year by year in the age group above 25 years. The most common age group was 55–79 years, accounting for approximately 50% of all incident cases. In terms of incidence and mortality rates, the overall net drifts were above 0. The local drifts in all age groups were above 0 in both sexes and males, while the local drifts in the 15–39 age groups were below 0 in females. The longitudinal age curves increased with age, with higher incidence and mortality rates, mainly in older age groups. The period rate ratios increased by year. The cohort rate ratios showed an upward trend before 1970 and fluctuated after 1975.

Conclusions

The burden of pancreatic cancer is still very high in China, and attention should be paid to the key population that is, males and older people. The results of our study can be used by policy makers to allocate resources efficiently to improve early diagnosis and treatment, improving the awareness of self-protection, and advocating a healthy lifestyle to prevent pancreatic cancer.

Vaccine usage and wastage in a designated Yellow Fever Vaccination Centre in North India

Purpose

Yellow fever is a viral hemorrhagic fever transmitted through the bite of mosquitoes. World Health Organization guidelines advocate a single dose of vaccine for life-long protective immunity against yellow fever. Yellow fever vaccine is included in routine childhood immunization schedules in countries at medium or high risk of yellow fever. For some travelers, visiting endemic countries, yellow fever vaccination is recommended to protect the travelers. We calculated the yellow fever vaccine wastage rate at a designated center in North India.

Materials and Methods

This is a record-based study. The data for the study was obtained from the immunization center of Government Medical College, Srinagar, Jammu and Kashmir. The particulars for every vaccine recipient were present in the register. The vaccine wastage rate was calculated. The analysis was done in IBM SPSS ver. 20.0 (IBM Corp., Armonk, NY, USA) and results were presented as numbers and frequencies.

Results

A total of 136 doses were issued out of which 111 doses were administered from November 2017 till October 2020. The maximum number of travelers was young adults (26.1%). In 83.7% of cases, the area of the visit was Africa. The vaccine wastage rate was 18.4%.

Conclusion

The vaccine wastage rate was not very high and was within that recommended for vaccines in routine immunization.

Preparedness of Primary Health Care Leaders During COVID-19 Outbreak, Riyadh, Saudi Arabia: A Qualitative Study

Purpose

Our study aims to explore the preparedness of the frontline leaders of the primary health care (PHC) centres in dealing with the COVID-19 pandemic and to understand their experiences in implementing preventive interventions necessary to routinise health care service delivery.

Methods

A qualitative exploratory study was conducted using in-depth interviews with the participants in English. The interviews were transcribed verbatim, and inductive coding followed by thematic analysis was performed using NVivo version 12.

Participants

Six participants in charge of managing their respective primary health care settings were included in the study. Purposive sampling was used to identify participants until saturation was reached. After agreement, the interviews were scheduled as per availability.

Results

The results were grouped into three major themes and nine subthemes. Most leaders reported that they were trained in pandemic preparedness, but there was a lack of focused readiness to handle a massive-scale, infectious disease outbreak or pandemic. The initial lack of guidelines specific to COVID-19 was a barrier in making decisions related to staff and patient care. Services were interrupted initially and there was lack of staff since many acquired COVID-19 and were isolated. The shortage of the staff was delt by repurposing staff from other departments to the essential care services. Fears related to pandemic was one of the main concerns reported among staff and patients. Several initiatives were taken to ensure staff safety and uninterrupted service delivery to patients. The use of technology was an effective mechanism in preparing for the pandemic.

Conclusion

This qualitative study helped in understanding the experiences of primary health care leaders during the COVID-19 pandemic. The facilities lacked overall preparedness at the beginning of the pandemic; however, many initiatives were taken in course of time to ensure smooth operations and continued service delivery to the patients.

Barriers to Diabetes Patients' Self-Care Practices in Eastern Ethiopia: A Qualitative Study from the Health Care Providers Perspective

BACKGROUND

All types of diabetes can damage the heart, blood vessels, eyes, kidneys, nerves and increase the overall risk of disability and premature death. Diabetes mellitus requires a range of self-care practices, scientifically recommended to control the glycemic level and maintain the patient's health. However, perceived barriers that hinder patients from fully implementing these diabetes self-care practices and obstacles have not been thoroughly explored. Therefore, this study aimed to explore the barriers to diabetes patients' self-care practices from the perspective of health care providers in two public hospitals in Harar City, Eastern Ethiopia.

METHODS

Researchers conducted an exploratory qualitative study among 26 health care providers working in two public hospitals from March to June 2021. The study participants were recruited from different disciplines working on diabetes care. Interviews were conducted in the Amharic language until the saturation point was reached. The interviews were tape-recorded, transcribed, and translated to English. Each transcript was read, re-read, and then exported to ATLAS.ti 7 software for coding. Field notes were used to supplement verbatim transcriptions. Initial codes were generated. The consistency between the two coders and their alignment with research questions were checked and applied to all subsequent transcripts after reached on consensus. The thematic analysis was employed in line with the primary set research question.

RESULTS

Researchers identified barriers to diabetes patients' self-care practices such as system, health care providers, and patient-level. These barriers were categorized under three main themes: lack of organized diabetes care services, limited collaborative care practices, and perceived lack of knowledge on self-care practices. In addition, the lack of multidisciplinary team care, lack of training for health care providers on diabetes self-care practices, and availability of laboratory tests and diabetes medication were prominent barriers.

CONCLUSION

Multi-level barriers to diabetes patients' self-care practices such as system, health care providers, and patients were identified. Therefore, interventions targeting proper service integration, building providers' and patients' capacity on diabetes self-care practices, and ensuring the sustainability of laboratory tests and medication supplies are essential. These interventions need to be accomplished through multi-level stakeholders' engagement and one-to-one or group interventions covering the multi-level challenges.

Obesity and the Bidirectional Risk of Cancer and Cardiovascular Diseases in African Americans: Disparity vs. Ancestry

Cardiovascular disease (CVD) and cancer often occur in the same individuals, in part due to the shared risk factors such as obesity. Obesity promotes adipose inflammation, which is pathogenically linked to both cardiovascular disease and cancer. Compared with Caucasians, the prevalence of obesity is significantly higher in African Americans (AA), who exhibit more pronounced inflammation and, in turn, suffer from a higher burden of CVD and cancer-related mortality. The mechanisms that underlie this association among obesity, inflammation, and the bidirectional risk of CVD and cancer, particularly in AA, remain to be determined. Socio-economic disparities such as lack of access to healthy and affordable food may promote obesity and exacerbate hypertension and other CVD risk factors in AA. In turn, the resulting pro-inflammatory milieu contributes to the higher burden of CVD and cancer in AA. Additionally, biological factors that regulate systemic inflammation may be contributory. Mutations in atypical chemokine receptor 1 (ACKR1), otherwise known as the Duffy antigen receptor for chemokines (DARC), confer protection against malaria. Many AAs carry a mutation in the gene encoding this receptor, resulting in loss of its expression. ACKR1 functions as a decoy chemokine receptor, thus dampening chemokine receptor activation and inflammation. Published and preliminary data in humans and mice genetically deficient in ACKR1 suggest that this common gene mutation may contribute to ethnic susceptibility to obesity-related disease, CVD, and cancer. In this narrative review, we present the evidence regarding obesity-related disparities in the bidirectional risk of CVD and cancer and also discuss the potential association of gene polymorphisms in AAs with emphasis on ACKR1.

Smartphone-Based mHealth and Internet of Things for Diabetes Control and Self-Management

In patients with chronic diseases condition, mobile health monitoring facility proves to play a significant role in providing significant assistance toward personal management. This research examined the use of smartphones by diabetes patients and their intentions to apply them for self-care and monitoring as well as management. This cross-sectional survey-based study was conducted in Jul-Aug 2021 with 200 diabetic patients (especially type 2) who were visiting specialized clinics and hospitals of Gujrat state, India. A validated questionnaire survey was designed to collect data, which included questions about demographics, information pertaining to other, use of cellphones, the Internet, and the intention to implement smartphones for diabetes monitoring, self-care, and self-management. A highest number of studied participants have mobile phone (97.5%) and smartphones (87%) and access the Internet on daily basis (83.5%). Younger participants were more inclined to use smartphone apps and have also shown more interest for continuous use in the future (p < 0.01). The majority of participants used apps for nutritional planning (85.5%), to monitor glucose control (76.5%), and for scheduling of diabetes appointments on the calendar (90.5%). Recommendations to use mobile app by doctors or healthcare profession were reported by 20.5% of the participants and attitude and future intention to use mobile apps were reported by the majority of participants. The majority of type 2 diabetes patients choose to use their cellphones and the internet or mobile phone reminder system for medication as well as to plan their diets, monitor their blood sugar levels, and communicate with their doctors. The findings of this research can be used to develop strategies and implement mHealth-based therapies to assist patients with type 2 diabetes to efficiently manage their health and might contribute to reducing patients' out-of-pocket expenditure as well as reducing disability-adjusted life years (DAILY) attributed by DM.

Nurses play a crucial role in this process. This article reviews and summarize latest findings of explore the role of primary care nurses and their support measures in response to COVID-19 and to identify challenges to achieving universal health coverage. The study revealed that there is vast panoply of strategic reforms. There are a number of differences and similarities such as mandatory political commitment and leadership, governance and policy, funding and allocation of resources, and engagement of communities and role of other stakeholders.

Fighting the 'tobacco epidemic' - A call to action to identify Targeted Intervention Points (TIPs) for better counseling patients with urothelial cancer

The association between tobacco use and urothelial cancer of the bladder is well known. Given the worsening tobacco epidemic, here we make the case for systematic targeted points of intervention for urologists and other professionals to intervene against bladder cancer. Awareness of contemporary checkpoints where we can intervene for counseling patients may help medical education in a tobacco-pandemic difficult setting.

A Qualitative Study on Medication Taking Behaviour Among People With Diabetes in Australia

Background: Australia has a high proportion of migrants with an increasing migration rate from India. Type II diabetes is a long-term condition common amongst the Indian population.

Aims: To investigate patients’ medication-taking behaviour and factors that influence adherence at the three phases of adherence.

Methods: Semi-structured interviews were conducted with a convenience sample of 23 Indian migrants living in Sydney. All interviews were audio-recorded, transcribed verbatim and thematically analysed.

Results: 1) Initiation: The majority of participants were initially prescribed oral antidiabetic medicine and only two were started on insulin. Most started taking their medicine immediately while some delayed initiating therapy due to fear of side-effects. 2) Implementation: Most participants reported taking their medicine as prescribed. However, some reported forgetting their medicine especially when they were in a hurry for work or were out for social events. 3) Discontinuation: A few participants discontinued taking their medicine. Those who discontinued did so to try Ayurvedic medicine. Their trial continued for a few weeks to a few years. Those who did not receive expected results from the Ayurvedic medicine restarted their prescribed conventional medicine.

Conclusion: A range of medication-taking behaviours were observed, ranging from delays in initiation to long-term discontinuation, and swapping of prescribed medicine with Ayurvedic medicine. This study highlights the need for tailored interventions, including education, that focus on factors that impact medication adherence from initiation to discontinuation of therapy.

Modeling and analysis of barriers in controlling TB: developing countries' perspective

Purpose

Tuberculosis (TB) continues to c-exist with humans despite many TB control programs and elimination strategies. This depicts that some barriers are not allowing achieving the desired results. The current study aims to focus on identification and ranking of such barriers to facilitate TB control programs in developing countries.

Design/methodology/approach

In the present study, 13 barriers that can influence success rate of TB elimination strategies have been recognized with an in-depth assessment of related literature and opinions of specialists from medical industry and academic world. The interpretive structural modeling (ISM) and decision-making trial and evaluation laboratory (DEMATEL) techniques have been employed for the ranking of barriers.

Findings

Based on driving power of barriers, the study coined that underinvestment is a major barrier followed by poor implementation of government policies and programs, poverty and poor primary health care infrastructure.

Research limitations/implications

The findings may guide healthcare service providers and researchers in analyzing the barriers and understanding the necessity of further advancements to decrease the count of already existing and incident cases.

Practical implications

Policy- and decision-makers may utilize the information on dependence and driving power of barriers for better planning and effective execution of TB control strategies.

Originality/value

Although a lot of literature is available on different barriers that are affecting success of TB strategies, the current study analyzes all the key barriers collectively for the prioritization of barriers.

Prevalence and trends of coronary artery disease risk factors and their effect on age of diagnosis in patients with established coronary artery disease: Tehran Heart Center (2005-2015)

BACKGROUND

Coronary artery disease (CAD) is a universal public health challenge, more prominently so in the low- and middle-income countries. In this study, we aimed to determine prevalence and trends of CAD risk factors in patients with documented CAD and to determine their effects on the age of CAD diagnosis.

MATERIALS AND METHODS

We conducted a registry-based, serial cross-sectional study using the coronary angiography data bank of the Tehran Heart Center. Adult patients who had obstructive (> 50% stenosis) CAD were included in the study. The prevalence and 11-year trends of conventional CAD risk factors were analyzed by sex and age, and their adjusted effects on the age of CAD diagnosis were calculated.

RESULTS

From January 2005 to December 2015, data for 90,094 patients were included in this analysis. A total of 61,684 (68.5%) were men and 28,410 (31.5%) were women. Men were younger at diagnosis than women, with a mean age of 60.1 in men and 63.2 in women (p < 0.001), and had fewer risk factors at the time of diagnosis. Mean age at diagnosis had an overall increasing trend during the study period. Increasing trend was seen in body-mass index, hypertension prevalence, diabetes mellitus. All lipid profile components (total cholesterol, low-density lipoprotein cholesterol, triglycerides, and high-density lipoprotein cholesterol) decreased over time. Of particular interest, opium consumption was associated with 2.2 year earlier age of CAD diagnosis.

CONCLUSION

The major results of this study (lower age of CAD diagnosis in men, lower age of diagnosis associated with most risk factors, and lower prevalence of serum lipids over time) were expected. A prominent finding of this study is confirming opium use was associated with a much younger age of CAD onset, even after adjusting for all other risk factors. In addition to recommendations for control of the traditional risk factors, spreading information about the potential adverse effect of opium use, which has only recently been associated with higher risk of CAD, may be necessary.

Prevalence of smartphone addiction and its relation with sleep disturbance and low self- esteem among medical college students

BACKGROUND

Use of smartphone is on the increase worldwide. They have revolutionized our lives to an extent that was unimaginable before the pandemic. Excessive use of smartphones reaching the levels of potential addiction among medical students and its relation to individual's sleep quality and self-esteem led us to study this prevalence.

AIM

This stuay aimed to study the prevalence of smartphone addiction and its relation with self-esteem and sleep disturbance in medical college students.

MATERIALS AND METHODS

A cross sectional analytical study was carried out and the prevalence of smartphone addiction, self- esteem, and sleep disturbance was measured using standardized questionnaires smartphone addiction scale short form, Rosenberg self esteem scale, Pittsburgh sleep quality index assessment respectively.

RESULTS

Prevalence of smartphone addiction among medical college students was 52%. Smartphone addiction was seen more in boys than girls. There was a significant association between the smartphone addiction and sleep disturbance. However, there was no significant association between smartphone addiction and low self-esteem.

CONCLUSION

The prevalence of smartphone addiction among medical students is found to be high and is associated with poor sleep.

Second Wave of the COVID-19 Pandemic in Delhi, India: High Seroprevalence Not a Deterrent?

Background We report the findings of a large follow-up, community-based, cross-sectional serosurvey and correlate it with the coronavirus disease (COVID-19) test-positivity rate and the caseload observed between the peaks of the first and the second wave of the COVID-19 pandemic in Delhi, India. Methodology Individuals aged five and above were recruited from 274 wards of the state (population approximately 19.6 million) from January 11 to January 22, 2021. A total of 100 participants each were included from all wards for a net sample size of approximately 28,000. A multistage sampling technique was employed to select participants for the household serosurvey. Anti-severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) immunoglobulin (IgG) antibodies were detected by using the VITROS® (Ortho Clinical Diagnostics, Raritan, NJ, USA) assay (90% sensitivity, 100% specificity). Results Antibody positivity was observed in 14,298 (50.76%) of 28,169 samples. The age, sex, and district population-weighted seroprevalence of the SARS-CoV-2 IgG was 50.52% (95% confidence interval [CI] = 49.94-51.10), and after adjustment for assay characteristics, it was 56.13% (95% CI = 55.49-56.77). On adjusted analysis, participants aged ≥50 years, of female gender, housewives, having ever lived in containment zones, urban slum dwellers, and diabetes or hypertensive patients had significantly higher odds of SARS-CoV-2 antibody positivity. The peak infection rate and the test-positivity rate since October 2020 were initially observed in mid-November 2020, with a subsequent steep declining trend, followed by a period of persistently low case burden lasting until the first week of March 2021. This was followed by a steady increase followed by an exponential surge in infections from April 2021 onward culminating in the second wave of the pandemic. Conclusions The presence of infection-induced immunity from SARS-CoV-2 even in more than one in two people can be ineffective in protecting the population. Despite such high seroprevalence, population susceptibility to COVID-19 can be accentuated by variants of concern having the ability for rapid transmission and depletion of antibody levels with the threat of recurrent infections, signifying the need for mass vaccination.

Association of road traffic noise exposure and prevalence of coronary artery disease: A cross-sectional study in North India

Epidemiological studies have established that noise from transportation sources exceeding the safe limits elevates the risk for cardiovascular diseases. The results however have remained heterogeneous. The present study was conducted to investigate the association between road traffic noise exposure and prevalence of coronary artery disease besides sub-group analysis was performed for identifying the most susceptible population. Traffic noise exposure was measured using the L_den metric in both continuous and categorical forms. A cross-sectional study was performed and information about sociodemographic, lifestyle, and health-related factors was collected. Noise level < 60 dB(A) representing the quiet areas was used as the reference group. Univariate and multivariate logistic regressions were performed to estimate the odds for self-reported coronary artery disease concerning road traffic noise after adjusting for confounding variables. The residents living in noisy areas were found to have a 2.25 times higher risk per 5 dB(A) increment in the noise levels (95% CI = 1.38 to 3.67). Males were at a higher risk of CAD (OR = 2.61; 95% CI = 1.84 to 3.72) as compared to females (OR = 2.07; 95% CI = 1.37-3.13). The subgroup analysis revealed that being sensitive to noise, belonging to a higher age group, reporting higher stress levels, and poor sleep quality were associated with higher risk. The study also provides evidence that exposure to noise levels greater than 60 dB(A) is associated with the prevalence of coronary artery disease in adults.

Health Systems and Services During COVID-19: Lessons and Evidence From Previous Crises: A Rapid Scoping Review to Inform the United Nations Research Roadmap for the COVID-19 Recovery

This rapid scoping review has informed the development of the November 2020 United Nations Research Roadmap for the COVID-19 Recovery, by providing a synthesis of available evidence on the impact of pandemics and epidemics on (1) essential services and (2) health systems preparedness and strengthening. Emerging findings point to existing disparities in health systems and services being further exacerbated, with marginalized populations and low- and middle-income countries burdened disproportionately. More broadly, there is a need to further understand short- and long-term impacts of bypassed essential services, quality assurance of services, the role of primary health care in the frontline, and the need for additional mechanisms for effective vaccine messaging and uptake during epidemics. The review also highlights how trust-of institutions, of science, and between communities and health systems-remains central to a successful pandemic response. Finally, previous crises had repeatedly foreshadowed the inability of health systems to handle upcoming pandemics, yet the reactive nature of policies and practices compounded by lack of resources, infrastructure, and political will have resulted in the current failed response to COVID-19. There is therefore an urgent need for investments in implementation science and for strategies to bridge this persistent research-practice gap.

Assessment of Factors Associated With Non-Compliance to Self-Management Practices in People With Type 2 Diabetes

Aim and objective Diabetes mellitus is a chronic metabolic disorder that requires continuous self-management practices. The aim of our study is to assess the factors resulting in non-compliance with self-management practices in people with type 2 diabetes mellitus (T2DM). Methods This cross-sectional study was conducted at Baqai Institute of Diabetology and Endocrinology (BIDE), a tertiary care center in Karachi, Pakistan, from March 2019 to May 2019. People with T2DM diagnosed for at least six months were included. A predesigned questionnaire was used to assess various components of self-management such as the use of oral hypoglycemic agents (OHAs) and insulin, self-monitoring of blood glucose (SMBG), physical activity, and daily foot care. Certified diabetes educators conducted interviews on a one-to-one basis. Data were entered and analyzed by using SPSS (version 20; IBM Corp., Armonk, NY). Results Better glycated hemoglobin (HbA1c) levels were observed in compliant persons and a statistically significant difference was noted in those who were compliant with insulin use. Good compliance with self-management was observed in people who were given diabetes education previously. A total of 205 people with T2DM were included in the study, with a mean age of 52.66 ± 11.2 years and a mean duration of diabetes of 8.9 ± 7.5 years. There were 62.9% males and 37.1% females. Oral hypoglycemic agents (OHAs) were prescribed to 62.9% while 33.9 % were on both OHAs and insulin. Non-compliance with the intake of OHAs was 33.3%, insulin injection 21%, SMBG 25.7%, physical activity 69.5%, and foot care practice 34.3%. Various reasons identified for non-compliance included forgetfulness (negligence) (88%), fear of hypoglycemia (10.6%), time constraints (48%), and lack of foot care knowledge (84.8%). Conclusion Non-compliance with T2DM self-management is multifactorial and needs continuous reinforcement of structured diabetes education sessions. The study showed that the provision of diabetes education is directly proportional to self-management compliance levels.

Causes of nonadherence to treatment in people with myocardial infarction: Content analysis

BACKGROUND

Nonadherence with the medication regimen in patients with heart disease can lead to treatment failure. The purpose of this study was to identify the causes of nonadherence in people with myocardial infarction.

MATERIALS AND METHODS

This study is a qualitative conventional content analysis. Data were collected through semistructured interviews. Thirteen individual interviews and a focus group were conducted with nurses, patients, and doctors. Data were analyzed using conventional content analysis.

RESULTS

Four main themes were identified, which are organizational-managerial causes and factors (drug-related problems, educational system-related problems, weak performance of hospitals, and problems related to insurance companies); sociocultural causes and factors (factors related to cultural problems and factors related to social problems); causes and factors related to care providers (skill problems of care providers and functional problems of care providers); and causes and factors associated with caregivers (factors related to social characteristics of the patient, factors related to patient characteristics, and factors related to the patient's belief).

CONCLUSIONS

Many individual and organizational factors affect nonadherence, which can be reduced by fundamental changes.

Impact of mobile phone dependence on behavior and academic performance of adolescents in selected schools of Uttarakhand, India

BACKGROUND

Mobile phones are one of the excellent gifts of technology in the 21^st century, which is most popular among adolescents. Today, mobile phones have infinite resources that have multiple benefits and applications. Its excessive use may impact adolescents in the form of behavioral changes and diminish the academic performance. This study explores the relationship between mobile phone usage with behavioral modifications and educational achievement among adolescents.

MATERIALS AND METHODS

A descriptive correlational study was conducted among adolescents (n = 285 -male-210, female-75) at selected schools of Rishikesh, Uttarakhand, India. The test of mobile dependence was used to assess the mobile phone dependence, and a behavioral Likert scale to evaluate the behavioral changes through the self-report method. The academic performance was observed by school records; percentage of the last two examination results was considered. Collected data were analyzed using descriptive and inferential statistics.

RESULTS

The study shows that 156 (54.70%) participants had a low mobile dependency, 191 (67%) participants had negative behavioral changes, and 125 (43.90%) participants had shown reduced academic performance due to overuse of the mobile phone. A significant relationship was seen between mobile phone dependency with behavioral changes (P < 0.001) and academic achievement (P < 0.035) seen among adolescents. Regression analysis predicted 49% of the differences among adolescents with selected variables due to the overuse of mobile phones.

CONCLUSION

The study concluded that mobile dependency changes adolescent's behavior as well as reduces their academic performance due to the overuse of the mobile phone.

Virtual learning during the COVID-19 pandemic: What are the barriers and how to overcome them?

CONTEXT

Virtual learning is not without challenges. It can cause stress, lack of motivation, and social isolation. Due to COVID-19 pandemic, our college shifted from face-to-face to virtual teaching-learning style. the aim was to find out the barriers in virtual learning among medical students and provide solutions to overcome them.

MATERIALS AND METHODS

This cross-sectional study was conducted among 3^rd- and 4^th-year Bachelor of Medicine and Bachelor of Surgery students in 2020. Prevalidated electronic survey forms on institutional barrier, technical barrier, and individual barrier were sent to students, 160 students responded. SPSS version 12 was used to calculate descriptive statistics and independent t-test.

RESULTS

The students had the highest mean score in individual barrier (mean: 2.82 [standard deviation (SD): 0.72]) followed by institutional barrier (mean: 2.79 [SD: 0.74]) and technological barrier (mean: 2.72 [SD: 0.75]). Regarding technological barriers, 38.6% of the students agreed difficulty in procurement of the laptop and 66.4% faced slow Internet connection. Regarding institutional barriers, 75.9% were stressed to join one lecture to another lecture as the lectures were continuous, 69.6% had limited opportunity to interact with lecturers, and 62.7% had poor communication between lecturers and students. Regarding individual barriers, 74.1% of the students were not motivated for online learning, 71.5% of the students could not learn as well as they were in the classroom, and 58.2% disagreed taking online courses in future.

CONCLUSION

Low motivation, communication, Internet connectivity, and technical problems were the main barriers. Smaller size class, highly motivated and well-trained lecturers, and interactive lectures may help in breaking the barriers of virtual learning.
