A qualitative exploration of purchasing, stockpiling, and use of drugs during the COVID-19 pandemic in an urban city of Bangladesh. PUBLIC HEALTH IN PRACTICE 2024; 7:100477. [PMID: 38379753 PMCID: PMC10878782 DOI: 10.1016/j.puhip.2024.100477] [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: 08/03/2023] [Revised: 02/03/2024] [Accepted: 02/09/2024] [Indexed: 02/22/2024] Open
Abstract
Objectives This research was conducted to explore the patterns and behavior of panic purchasing, stockpiling, and use of drugs during COVID-19 in the Sylhet city, Bangladesh. Study design The study adopted qualitative exploratory research design. Methods 25 in-depth interviews with drug sellers and clients and 7 key informant interviews were conducted with pharmacists and medical representatives of pharmaceutical companies in Sylhet city in Bangladesh from October 2020 to March 2021. Thematic analysis was used to evaluate the primary data. Results The findings revealed that individuals sought out, purchased, and stockpiled prescription-only drugs for self-medication purposes during the COVID-19 pandemic. News and rumor spread by social media, television, and everyday interactions concerning the severity of infections and the number of deaths caused an increase in self-medication as a preventive measure. The reason for this panic buying of drugs was identified as a fear of drug shortages, price hikes, the rise of infection, and the availability of medicines and home delivery services during the pandemic. Conclusion The purchasing, stockpiling and use of drugs by pharmacies varied based on the person dispensing the drugs, the customer, and the COVID-19 pandemic situation. Furthermore, the role of social media in spreading rumor and (dis) misinformation about drug use, a greater tendency to self-medicate, and poor regulation, influenced the individual's use of drugs. Therefore, the drug regulatory authorities and policymakers need to consider the real level of local drug use in order to encourage more rational use of drugs which will help to ensure that there is reliable access to safe, effective, and high-quality medicines and vaccines for all.

Clinical features and outcomes of COVID-19 patients with concomitant herpesvirus co-infection or reactivation: A systematic review. New Microbes New Infect 2024; 58:101233. [PMID: 38425457 PMCID: PMC10901905 DOI: 10.1016/j.nmni.2024.101233] [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: 09/29/2023] [Revised: 02/11/2024] [Accepted: 02/14/2024] [Indexed: 03/02/2024] Open
Abstract
Background Since the first case of COVID-19 was diagnosed in Wuhan, China in late 2019, concomitant infections with Herpesviridae were documented that were presented from simple skin manifestations to severe life-threatening conditions that may lead to mortality. In this systematic review, we have included studies conducted in different parts of the world to find out the association of clinical features and outcomes of COVID-19 infection and concomitant Herpesviridae infection. Methods A comprehensive search was conducted in electronic databases including Medline through PubMed, Cochrane database, Scopus and Web of science (core collection). Two review authors independently screened the articles and extracted data. The Risk of bias assessment was done by using RoBANS tool. Results A total of 919 studies were retrieved and 19 studies were included having data of 539 patients who were infected with both COVID-19 and Herpesviridae. Herpes Simplex-1, Varicella Zoster, Cytomegalovirus, Epstein-Barr virus and Human Herpes Virus-6 were the detected viruses in the included studies. Cytomegalovirus (CMV) reactivation was the most detected concomitant infection. In case of reactivation with more than one Herpes virus mortality among patients were detected along with single viral infection in some studies. Significant association was noted in dosage and usage of steroid and Herpesviridae reactivation in COVID-19 patients. Blood markers such as D-dimer, CRP along with length of stay in the ICU and usage of invasive mechanical ventilation were found to be the significantly associated markers. Conclusion Findings from this study will aid clinicians to assess and treat COVID-19 cases with co-infections.

Association of HLA gene polymorphisms with Helicobacter pylori related gastric cancer-a systematic review. HLA 2024; 103:e15394. [PMID: 38372631 DOI: 10.1111/tan.15394] [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: 08/22/2023] [Revised: 01/28/2024] [Accepted: 02/01/2024] [Indexed: 02/20/2024]
Abstract
The appropriate host cell immune responses for the progression of several diseases, including gastric or stomach cancer (GC), are significantly influenced by HLA polymorphisms. Our objective was to systematically review the evidence linking HLA polymorphisms with the risk of Helicobacter. pylori related GC. We conducted a comprehensive literature search to identify studies published between 2000 and April 2023 on the association of HLA polymorphisms with H. pylori related GC using databases such as Medline through PubMed, Embase, Web of Science (core collection), The Cochrane Library, and Scopus. Two authors independently screened articles, extracted data, and assessed the risk of bias using the Risk of Bias Assessment tool for Non-randomized Studies. From 7872 retrieved studies, 19 met inclusion criteria, encompassing 1656 cases and 16,787 controls across four World Health Organization regions, with Japan contributing the most studies. We explored HLA-A/B/C, HLA-DRB1/DQA1/DQB1, HLA-G, and MICA alleles. Of 29 significant HLA polymorphisms identified, 18 showed a positive association with GC, whereas 11 were negatively associated. HLA-DQB1*06 allele was most frequently associated to susceptibility, as reported in four studies, followed by HLA-DRB1*04 and HLA-DQA1*01, each reported in two studies. Conversely, HLA-G*01, HLA-DQA1*01, HLA-DQA1*05, and HLA-DQB1*03 were identified as protective in two studies each. Additionally, five genotypes and six haplotypes were reported as positive, whereas three genotypes and two haplotypes were negative factors for the disease incidence or mortality. Despite heterogeneity in the study population and types of HLA polymorphisms examined, our analysis indicates certain polymorphisms are associated with H. pylori related GC progression and mortality in specific populations.

Monitoring and evaluation practices and operational research during public health emergencies in southeast Asia region (2012-2022) - a systematic review. THE LANCET REGIONAL HEALTH. SOUTHEAST ASIA 2024; 21:100340. [PMID: 38361592 PMCID: PMC10866922 DOI: 10.1016/j.lansea.2023.100340] [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: 01/16/2023] [Revised: 11/01/2023] [Accepted: 11/22/2023] [Indexed: 02/17/2024]
Abstract
This systematic review aimed to explore the monitoring and evaluation (M&E) and operational research (OR) practices during public health emergencies (PHE) in the southeast Asian region (SEAR) over the last decade. We searched electronic databases and grey literature sources for studies published between 2012 and 2022. The studies written in English were included, and a narrative synthesis was undertaken. A total of 29 studies were included in this review. Among these 25 studies documented M&E and four studies documented OR practices. The majority of the studies were from India and Bangladesh, with no evidence found from Sri Lanka, Bhutan, Myanmar, and Timor-Leste. M&E of surveillance programs were identified among which PHE due to COVID-19 was most prevalent. M&E was conducted in response to COVID-19, cholera, Nipah, Ebola, Candida auris, and hepatitis A. OR practice was minimal and reported from India and Indonesia. India conducted OR on COVID-19 and malaria, whereas Indonesia focused on COVID-19 and influenza. While most SEAR countries have mechanisms for conducting M&E, there is a noticeable limitation in OR practices. There is a compelling need to develop a standard framework for M&E. Additionally, enhancing private sector engagement is crucial for strengthening preparedness against PHE. Furthermore, there is a necessity to increase awareness about the importance of conducting M&E and OR during PHE.

Oral killed cholera vaccines for preventing cholera. Cochrane Database Syst Rev 2024; 1:CD014573. [PMID: 38197546 PMCID: PMC10777452 DOI: 10.1002/14651858.cd014573] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Indexed: 01/11/2024]
Abstract
BACKGROUND Cholera causes acute watery diarrhoea and death if not properly treated. Outbreaks occur in areas with poor sanitation, including refugee camps. Several vaccines have been developed and tested over the last 50 years. This is an update of a Cochrane review, originally published in 1998, which explored the effects of all vaccines for preventing cholera. This review examines oral vaccines made from killed bacteria. OBJECTIVES To assess the effectiveness and safety of the available World Health Organization (WHO)-prequalified oral killed cholera vaccines among children and adults. SEARCH METHODS We searched the Cochrane Infectious Diseases Group Specialized Register; CENTRAL, MEDLINE; Embase; LILACS; and two trials registers (February 2023). SELECTION CRITERIA We included randomized controlled trials (RCTs), including cluster-RCTs. There were no restrictions on the age and sex of the participants or the setting of the study. We considered any available WHO-prequalified oral killed cholera vaccine as an intervention. The control group was given a placebo, another vaccine, or no vaccine. The outcomes were related to vaccine effectiveness and safety. We included articles published in English only. DATA COLLECTION AND ANALYSIS Two review authors independently applied the inclusion criteria and extracted data from included studies. We assessed the risk of bias using the Cochrane ROB 1 assessment tool. We used the generic inverse variance and a random-effects model meta-analysis to estimate the pooled effect of the interventions. We assessed the certainty of the evidence using the GRADE approach. For vaccine effectiveness (VE), we converted the overall risk ratio (RR) to vaccine effectiveness using the formula: VE = (1 - RR) x 100%. MAIN RESULTS Five RCTs, reported in 12 records, with 462,754 participants, met the inclusion criteria. We identified trials on whole-cell plus recombinant vaccine (WC-rBS vaccine (Dukoral)) from Peru and trials on bivalent whole-cell vaccine (BivWC (Shanchol)) vaccine from India and Bangladesh. We did not identify any trials on other BivWC vaccines (Euvichol/Euvichol-Plus), or Hillchol. Two doses of Dukoral with or without a booster dose reduces cases of cholera at two-year follow-up in a general population of children and adults, and at five-month follow-up in an adult male population (overall VE 76%; RR 0.24, 95% confidence interval (CI) 0.08 to 0.65; 2 trials, 16,423 participants; high-certainty evidence). Two doses of Shanchol reduces cases of cholera at one-year follow-up (overall VE 37%; RR 0.63, 95% CI 0.47 to 0.85; 2 trials, 241,631 participants; high-certainty evidence), at two-year follow-up (overall VE 64%; RR 0.36, 95% CI 0.16 to 0.81; 2 trials, 168,540 participants; moderate-certainty evidence), and at five-year follow-up (overall VE 80%; RR 0.20, 95% CI 0.15 to 0.26; 1 trial, 54,519 participants; high-certainty evidence). A single dose of Shanchol reduces cases of cholera at six-month follow-up (overall VE 40%; RR 0.60, 95% CI 0.47 to 0.77; 1 trial, 204,700 participants; high-certainty evidence), and at two-year follow-up (overall VE 39%; RR 0.61, 95% CI 0.53 to 0.70; 1 trial, 204,700 participants; high-certainty evidence). A single dose of Shanchol also reduces cases of severe dehydrating cholera at six-month follow-up (overall VE 63%; RR 0.37, 95% CI 0.28 to 0.50; 1 trial, 204,700 participants; high-certainty evidence), and at two-year follow-up (overall VE 50%; RR 0.50, 95% CI 0.42 to 0.60; 1 trial, 204,700 participants; high-certainty evidence). We found no differences in the reporting of adverse events due to vaccination between the vaccine and control/placebo groups. AUTHORS' CONCLUSIONS Two doses of Dukoral reduces cases of cholera at two-year follow-up. Two doses of Shanchol reduces cases of cholera at five-year follow-up, and a single dose of Shanchol reduces cases of cholera at two-year follow-up. Overall, the vaccines were safe and well-tolerated. We found no trials on other BivWC vaccines (Euvichol/Euvichol-Plus). However, BivWC products (Shanchol, Euvichol/Euvichol-Plus) are considered to produce comparable vibriocidal responses. Therefore, it is reasonable to apply the results from Shanchol trials to the other BivWC products (Euvichol/Euvichol-Plus).

Gut microbiota shifts favorably with delivery of handwashing with soap and water treatment intervention in a prospective cohort (CHoBI7 trial). JOURNAL OF HEALTH, POPULATION, AND NUTRITION 2023; 42:146. [PMID: 38129922 PMCID: PMC10740293 DOI: 10.1186/s41043-023-00477-0] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 04/18/2022] [Accepted: 11/21/2023] [Indexed: 12/23/2023]
Abstract
BACKGROUND Cholera can result in the expulsion of important microbiota from the gut and result in death if left untreated. The disease transmits mainly via drinking water carrying Vibrio cholerae; and household contacts (HHC) of cholera patients are at elevated risk during the first week of infection. The gut microbiota profiles of HHC-children of cholera patients at Dhaka city slums were investigated before (day 0) and after (day 8) delivery of chlorinated water as part of the major study 'CHoBI7 trial (cholera-hospital-based intervention for 7 days)'. RESULT Results of sequencing and analysis of bacterial community DNA revealed the predominance of two bacterial phyla: Bacteroidetes and Firmicutes at day 0 with a relative abundance of 62 ± 6 (mean ± SEM%) and 32 ± 7, respectively. The pattern reversed at day 8 with a decreased relative abundance of Bacteroidetes (39 ± 12; p = 0.034) and an increased abundance of Firmicutes (49 ± 12; p = 0.057). Of 65 bacterial families confirmed at day 0, six belonging to Proteobacteria including Vibrionaceae disappeared at day 8. Interestingly, the relative abundance of four Firmicutes families-Lachnospiraceae, Bifidobacteriaceae, Clostridiaceae, and Ruminococcaceae was increased in all five study children at day 8. CONCLUSION The observed exclusion of pathogenic Proteobacteria and enhancement of beneficial Firmicutes in the gut of children delivered with chlorinated water as part of WASH intervention reflect a great promise of the CHoBI7 program in preventing cholera and improving child health.

The burden of diseases and risk factors in Bangladesh, 1990-2019: a systematic analysis for the Global Burden of Disease Study 2019. Lancet Glob Health 2023; 11:e1931-e1942. [PMID: 37973341 PMCID: PMC10664824 DOI: 10.1016/s2214-109x(23)00432-1] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/16/2023] [Revised: 08/07/2023] [Accepted: 09/06/2023] [Indexed: 11/19/2023]
Abstract
BACKGROUND Bangladesh has made substantial progress in improving socioeconomic and health indicators over the past 50 years, but data on national disease burden are scarce. We used data from the Global Burden of Diseases, Injuries, and Risk Factors Study (GBD) 2019 to estimate the burden of diseases and risk factors in Bangladesh from 1990 to 2019. METHODS For this systematic analysis, we analysed data from vital registration systems, surveys, and censuses using multistage modelling processes to estimate life expectancy at birth, mortality rate, years of life lost (YLLs), years lived with disability (YLDs), and disability-adjusted life-years (DALYs). Additionally, we compared the health status of Bangladesh with that of the other countries in the GBD south Asia region-Bhutan, India, Nepal, and Pakistan. FINDINGS Life expectancy at birth in Bangladesh increased from 58·2 years (95% uncertainty interval 57·1-59·2) in 1990 to 74·6 years (72·4-76·7) in 2019. Between 1990 and 2019, the age-standardised mortality rate decreased from 1509·3 (1428·6-1592·1) to 714·4 (604·9-838·2) deaths per 100 000 population. In 2019, non-communicable diseases represented 14 of the top 20 causes of death; the leading three causes were stroke, ischaemic heart disease, and chronic obstructive pulmonary disease. High blood pressure, high fasting plasma glucose, and smoking were the top three risk factors. From 1990 to 2019, the rate of all-cause DALYs decreased by 54·9% (48·8-60·4). In 2019, the leading causes of DALYs and YLLs were neonatal disorders, stroke, and ischaemic heart disease, whereas musculoskeletal disorders, depressive disorders, and low back pain were the leading causes of YLDs. Bangladesh has the lowest age-standardised rates of mortality, YLDs, and YLLs and the highest life expectancy at birth in south Asia. INTERPRETATION Over the past 30 years, mortality rates have reduced by more than half in Bangladesh. Bangladesh must now address the double burden of communicable and non-communicable diseases. Cost-effective, multisectoral efforts are needed to prevent and control non-communicable diseases, promote healthy lifestyles, and prevent premature mortality and disabilities.

Association of psychological factors with advanced-level functional competency: Findings from the Aichi workers' cohort study, 2002-2019. Heliyon 2023; 9:e21931. [PMID: 38027964 PMCID: PMC10665718 DOI: 10.1016/j.heliyon.2023.e21931] [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: 01/29/2023] [Revised: 10/15/2023] [Accepted: 10/31/2023] [Indexed: 12/01/2023] Open
Abstract
Objective This study examined the longitudinal association of perceived stress, ikigai, and having someone one can count on in middle age with the advanced-level functional competency in older age, which is crucial for the maintenance of independent life among older adults. The issue is especially relevant in super-aged countries like contemporary Japan, where more and more older people live in a household consisting only of older people. Methods Data were collected in 2019 from a total of 1692 retirees of the Aichi Workers' Cohort Study participants in which baseline survey including psychological factors was conducted during their employment in 2002. Japan Science and Technology Agency Index of Competence (JST-IC) was used to measure the advanced-level functional competency. Multivariable-adjusted odds ratios (ORs) were obtained for having low JST-IC in later life by the degrees of psychological factors reported in the middle age adjusting for the presence of depressive mood in 2019. Results Those who were not sure about ikigai (OR: 2.02, 95 % CI: 1.33 to 3.08) and who have no one to count on (OR: 2.19, 95 % CI: 1.52 to 3.16) in the middle age were significantly associated with low JST-IC after retirement. Having much stress was significantly inversely associated with a low JST-IC (OR: 0.69, 95 % CI: 0.50 to 0.97). Conclusion Having ikigai and someone reliable, and stress during middle age might play a role in preventing impaired advanced-level functional competency. Improved ikigai and increased social interaction and support might improve functional competency. Further research might explore avenues for improving ikigai.

Good death for people living with dementia: a qualitative study. BMC Geriatr 2023; 23:665. [PMID: 37845634 PMCID: PMC10580641 DOI: 10.1186/s12877-023-04395-y] [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: 12/19/2022] [Accepted: 10/09/2023] [Indexed: 10/18/2023] Open
Abstract
BACKGROUND Ensuring a good death is one of the primary objectives of palliative care and end-of-life care. There is insufficient evidence regarding what defines a good death for people living with dementia. Obtaining an understanding of what constitutes a good death could help improve dementia care. This study aimed to explore how multiple stakeholders perceive a good death for people living with dementia. METHODS This qualitative study was carried out across six prefectures in Japan. Enrollment of participants took place within dementia outpatient clinics, hospitals, daycare centers, and community centers. A total of thirty-three in-depth interviews with people living with dementia, physicians, and nurses were conducted. Six focus group discussions were performed with family caregivers and care workers. Verbatim transcripts of the interviews were prepared, and inductive content analysis was used to examine the data. FINDINGS Regarding the perception of a good death, the following themes were derived: (1) painless death; (2) dying in a preferred environment; (3) family's coping with loss; (4) maintaining regular life; (5) living with respect; and (6) preparation for death. All these themes are interrelated. Participants viewed a good death as a process rather than a single event. CONCLUSION This study identifies crucial components of a good death for people living with dementia. The findings could be used to improve dementia care.

Abstract
AIM Technology including artificial intelligence (AI) may play a key role to strengthen primary health care services in resource-poor settings. This systematic review aims to explore the evidence on the use of AI and digital health in improving primary health care service delivery. METHODS Three electronic databases were searched using a comprehensive search strategy without providing any restriction in June 2023. Retrieved articles were screened independently using the "Rayyan" software. Data extraction and quality assessment were conducted independently by two review authors. A narrative synthesis of the included interventions was conducted. RESULTS A total of 4596 articles were screened, and finally, 48 articles were included from 21 different countries published between 2013 and 2021. The main focus of the included studies was noncommunicable diseases (n = 15), maternal and child health care (n = 11), primary care (n = 8), infectious diseases including tuberculosis, leprosy, and HIV (n = 7), and mental health (n = 6). Included studies considered interventions using AI, and digital health of which mobile-phone-based interventions were prominent. m-health interventions were well adopted and easy to use and improved the record-keeping, service deliver, and patient satisfaction. CONCLUSION AI and the application of digital technologies improve primary health care service delivery in resource-poor settings in various ways. However, in most of the cases, the application of AI and digital health is implemented through m-health. There is a great scope to conduct further research exploring the interventions on a large scale.

Abstract
BACKGROUND Diabetes is one of the leading causes of death and disability worldwide, and affects people regardless of country, age group, or sex. Using the most recent evidentiary and analytical framework from the Global Burden of Diseases, Injuries, and Risk Factors Study (GBD), we produced location-specific, age-specific, and sex-specific estimates of diabetes prevalence and burden from 1990 to 2021, the proportion of type 1 and type 2 diabetes in 2021, the proportion of the type 2 diabetes burden attributable to selected risk factors, and projections of diabetes prevalence through 2050. METHODS Estimates of diabetes prevalence and burden were computed in 204 countries and territories, across 25 age groups, for males and females separately and combined; these estimates comprised lost years of healthy life, measured in disability-adjusted life-years (DALYs; defined as the sum of years of life lost [YLLs] and years lived with disability [YLDs]). We used the Cause of Death Ensemble model (CODEm) approach to estimate deaths due to diabetes, incorporating 25 666 location-years of data from vital registration and verbal autopsy reports in separate total (including both type 1 and type 2 diabetes) and type-specific models. Other forms of diabetes, including gestational and monogenic diabetes, were not explicitly modelled. Total and type 1 diabetes prevalence was estimated by use of a Bayesian meta-regression modelling tool, DisMod-MR 2.1, to analyse 1527 location-years of data from the scientific literature, survey microdata, and insurance claims; type 2 diabetes estimates were computed by subtracting type 1 diabetes from total estimates. Mortality and prevalence estimates, along with standard life expectancy and disability weights, were used to calculate YLLs, YLDs, and DALYs. When appropriate, we extrapolated estimates to a hypothetical population with a standardised age structure to allow comparison in populations with different age structures. We used the comparative risk assessment framework to estimate the risk-attributable type 2 diabetes burden for 16 risk factors falling under risk categories including environmental and occupational factors, tobacco use, high alcohol use, high body-mass index (BMI), dietary factors, and low physical activity. Using a regression framework, we forecast type 1 and type 2 diabetes prevalence through 2050 with Socio-demographic Index (SDI) and high BMI as predictors, respectively. FINDINGS In 2021, there were 529 million (95% uncertainty interval [UI] 500-564) people living with diabetes worldwide, and the global age-standardised total diabetes prevalence was 6·1% (5·8-6·5). At the super-region level, the highest age-standardised rates were observed in north Africa and the Middle East (9·3% [8·7-9·9]) and, at the regional level, in Oceania (12·3% [11·5-13·0]). Nationally, Qatar had the world's highest age-specific prevalence of diabetes, at 76·1% (73·1-79·5) in individuals aged 75-79 years. Total diabetes prevalence-especially among older adults-primarily reflects type 2 diabetes, which in 2021 accounted for 96·0% (95·1-96·8) of diabetes cases and 95·4% (94·9-95·9) of diabetes DALYs worldwide. In 2021, 52·2% (25·5-71·8) of global type 2 diabetes DALYs were attributable to high BMI. The contribution of high BMI to type 2 diabetes DALYs rose by 24·3% (18·5-30·4) worldwide between 1990 and 2021. By 2050, more than 1·31 billion (1·22-1·39) people are projected to have diabetes, with expected age-standardised total diabetes prevalence rates greater than 10% in two super-regions: 16·8% (16·1-17·6) in north Africa and the Middle East and 11·3% (10·8-11·9) in Latin America and Caribbean. By 2050, 89 (43·6%) of 204 countries and territories will have an age-standardised rate greater than 10%. INTERPRETATION Diabetes remains a substantial public health issue. Type 2 diabetes, which makes up the bulk of diabetes cases, is largely preventable and, in some cases, potentially reversible if identified and managed early in the disease course. However, all evidence indicates that diabetes prevalence is increasing worldwide, primarily due to a rise in obesity caused by multiple factors. Preventing and controlling type 2 diabetes remains an ongoing challenge. It is essential to better understand disparities in risk factor profiles and diabetes burden across populations, to inform strategies to successfully control diabetes risk factors within the context of multiple and complex drivers.

Effect of leisure-time physical activity on blood pressure in people with hypertension: a systematic review and meta-analysis. Sci Rep 2023; 13:10639. [PMID: 37391436 PMCID: PMC10313796 DOI: 10.1038/s41598-023-37149-2] [Citation(s) in RCA: 3] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/16/2022] [Accepted: 06/16/2023] [Indexed: 07/02/2023] Open
Abstract
High blood pressure is a major risk factor for premature death. Leisure-time physical activities have been recommended to control hypertension. Studies examining how leisure-time physical activity affects blood pressure have found mixed results. We aimed to conduct a systematic review examining the effect of leisure-time physical activity (LTPA) on lowering blood pressure among adults living with hypertension. We searched studies in Embase, Medline/PubMed, Web of Science, Physical Education Index, Scopus and CENTRAL (the Cochrane Library). The primary outcome variables were systolic blood pressure (SBP) and diastolic blood pressure (DBP). This systematic review is registered on PROSPERO (CRD42021260751). We included 17 studies out of 12,046 screened articles in this review. Moderate-intensity LTPA (all types) reduced SBP compared to the non-intervention control group (MD -5.35 mm Hg, 95% CI -8.06 to -2.65, nine trials, n = 531, low certainty of the evidence). Mean DBP was reduced by -4.76 mm Hg (95% CI -8.35 to -1.17, nine trials, n = 531, low certainty of the evidence) in all types of LTPA (moderate intensity) group compared to the non-intervention control group. Leisure-time walking reduced mean SBP by -8.36 mmHg, 95% CI -13.39 to -3.32, three trials, n = 128, low certainty of the evidence). Walking during leisure time reduced -5.03 mmHg mean DBP, 95% CI -8.23 to -1.84, three trials, n = 128, low certainty of the evidence). Performing physical activity during free time probably reduces SBP and DBP (low certainty of the evidence) among adults with hypertension.

Stool specimen for diagnosis of pulmonary tuberculosis in adults: a systematic review. BMJ Open 2023; 13:e062135. [PMID: 37105702 PMCID: PMC10151869 DOI: 10.1136/bmjopen-2022-062135] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/18/2022] [Accepted: 04/18/2023] [Indexed: 04/29/2023] Open
Abstract
OBJECTIVE To assess the diagnostic accuracy of stool specimens to diagnose pulmonary tuberculosis (PTB) in adults. DESIGN Systematic review. DATA SOURCES MEDLINE (Ovid), Embase (Ovid), Web of Science and the Cochrane database were searched from inception to 9 March 2023-10 March 2023 using a comprehensive search strategy; reference lists of selected articles and relevant review articles were manually searched. ELIGIBILITY CRITERIA FOR SELECTING STUDIES Studies in English reporting diagnostic performance of stool specimens against respiratory specimens using mycobacterial culture or smear microscopy or Xpert assay to diagnose PTB in adults were eligible for this systematic review. DATA EXTRACTION AND SYNTHESIS Two reviewers independently screened the retrieved citations and extracted data. The risk of bias and applicability of results were assessed using the Quality Assessment of Diagnostic Accuracy Studies-2 tool. Narrative data synthesis was performed. RESULTS A total of 1658 citations were screened, and 28 full-text articles were assessed. Nine studies met the inclusion criteria. The reported sensitivity and specificity of stool culture varied between 21.4% and 63.9%, and 61.5% and 100%, respectively. In stool smear microscopy, sensitivities and specificities ranged from 12.1% to 53.9%, and from 79.5% to 100%, respectively. The reported sensitivities of PCR assays, including Xpert assays, ranged from 69.7% to 100%, with specificities ranging from 69.8% to 100%. Most of the studies had a low risk of bias and a low applicability concern in all domains. CONCLUSION This systematic review could not conclude on the diagnostic accuracy of stool specimens for PTB diagnosis in adults. Further studies are required to evaluate the accuracy of stool specimens in adults to enable meta-analyses in updates of this review as well as other systematic reviews.

Aducanumab for the treatment of Alzheimer's disease: a systematic review. Psychogeriatrics 2023; 23:512-522. [PMID: 36775284 DOI: 10.1111/psyg.12944] [Citation(s) in RCA: 17] [Impact Index Per Article: 17.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/05/2022] [Revised: 01/11/2023] [Accepted: 01/26/2023] [Indexed: 02/14/2023]
Abstract
Aducanumab is a novel disease-modifying anti-amyloid-beta (Aβ) human monoclonal antibody specifically targeted to the pathophysiology of Alzheimer's disease (AD). It was granted for treating AD in June 2021 by the United States Food and Drug Administration. We systematically analyzed available trials to evaluate the efficacy and safety of aducanumab treating AD. We followed the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analysis) guidelines. We conducted an extensive literature search using the electronic databases MEDLINE through PubMed, EMBASE, Cochrane, Web of Science, and Scopus for suitable studies on aducanumab. We considered human clinical trials of aducanumab, assessing its efficacy and adverse effects in treating AD, excluding any experimental animal studies. We included three randomised controlled trials. Studies reported that aducanumab reduced brain amyloid-beta plaques in a time- and dose-dependent manner (dose-response, P < 0.05) and a slowed decline in cognition (22% reduction) in the high-dose treated group, difference of -0.39 versus placebo in Clinical Dementia Rating Scale Sum Boxes (95% CI, -0.69 to -0.09; P = 0.012) along with a reduced amyloid positron emission tomography standard uptake value ratio score (P < 0.001) and plasma p181-tau (phosphorylated tau) level. Amyloid-related imaging abnormality was reported as a serious adverse event and was profound in high-dose treated group (425/1029 in 10 mg/kg). Aducanumab has been reported to affect two main pathophysiologic hallmarks (Aβ and tau) of AD. We suggest future studies addressing aducanumab's efficacy and safety to confirm that the benefit of this drug outweighs the risk.

Abstract
Several phase-1 clinical trials have been performed to evaluate the safety and efficacy of candidate anti-Zika vaccines. In this systematic review, we systematically evaluated the safety and immunogenicity of candidate vaccines, which would aid researchers in formulating an effective vaccination strategy for phase-2 trials based on current evidence. A literature search was conducted using the electronic databases MEDLINE through Pubmed, Web of Science, and Cochrane Database for relevant studies on candidate anti-zika vaccines. Studies on animal models were excluded from our study. Healthy individuals who were administered candidate Zika vaccines to evaluate the immune response and adverse events (AEs) compared to placebo were considered. Data were extracted, tabulated, and analysed using Microsoft Excel, while the risk of bias plots were generated using tidyverse and Robvis packages in R-studio. A total of five phase-1 clinical trials were included in our analysis comprising of studies on inactivated, viral vector, and DNA vaccines. Immunogenicity ranged from 10% to 100% after vaccination with the lowest seroconversion rate (10%) and geometric mean titre (GMT) (6.3; 95% confidence interval (CI):3.7-10.8) observed among recipients of single-dose inactivated anti-zika vaccine (ZPIV). For DNA vaccines, the seroconversion rate ranged from 60% to 100% with the highest seroconversion rate (100%) and GMT (2871; 95% CI:705.3-11688) observed among recipients of three shots of high dose GLS-5700 vaccine. For viral vector vaccine (Ad26.ZIKV.001) seroconversion rate (100%) and GMT peaked after two shots with both low and high-dose vaccines. In all those studies AEs were mostly local including injection site pain, erythema, and itching. The most common systemic AEs included fever, myalgia, nausea, and fatigue. In phase-1 clinical trials, all candidate vaccines were found to be highly immunogenic and relatively safe, especially when administered in higher doses and with the help of needle-free devices.

Abstract
INTRODUCTION Stroke is the second leading cause of death and morbidity across the globe. In low-income and middle-income countries (LMICs), it has become an overwhelming burden over the past few decades. This burden is escalating at a much greater pace compared with that of high-income countries. It is considered the most frequent cause of adult disability that affects the quality of life. 'Prevention' is one of the key components to combating stroke. In this regard, community-based interventions can play a vital role in improving population-level health and well-being. Considering the escalating trend of stroke in LMICs, this systematic review aims to map the available community-based interventions in preventing stroke and to conduct further analysis regarding the effectiveness of the identified interventions. METHODS AND ANALYSIS We have searched Medline, Web of Science and Scopus using a comprehensive search strategy in October 2021. Two reviewers will independently perform screening, data extraction and risk of bias (ROB) assessment. The ROB assessment and applicability of results of eligible studies will be performed using the Cochrane ROB tool for assessing randomised controlled trials and the ROBANS (Risk Of Bias Assessment tool for Non-randomised Studies) to assess non-randomised studies. A random-effect model meta-analysis will be used to calculate pooled results and to obtain weighted OR and risk ratio of incidence of stroke along with corresponding 95% CI. ETHICS AND DISSEMINATION The results will be disseminated through publishing in a peer-reviewed journal and public presentations at relevant national and international conferences. Ethical approval is not required as this is a systematic review of publicly available data. PROSPERO REGISTRATION NUMBER CRD42021283670.

Population-level risks of alcohol consumption by amount, geography, age, sex, and year: a systematic analysis for the Global Burden of Disease Study 2020. Lancet 2022; 400:185-235. [PMID: 35843246 PMCID: PMC9289789 DOI: 10.1016/s0140-6736(22)00847-9] [Citation(s) in RCA: 122] [Impact Index Per Article: 61.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/18/2021] [Revised: 04/11/2022] [Accepted: 04/26/2022] [Indexed: 12/12/2022]
Abstract
BACKGROUND The health risks associated with moderate alcohol consumption continue to be debated. Small amounts of alcohol might lower the risk of some health outcomes but increase the risk of others, suggesting that the overall risk depends, in part, on background disease rates, which vary by region, age, sex, and year. METHODS For this analysis, we constructed burden-weighted dose-response relative risk curves across 22 health outcomes to estimate the theoretical minimum risk exposure level (TMREL) and non-drinker equivalence (NDE), the consumption level at which the health risk is equivalent to that of a non-drinker, using disease rates from the Global Burden of Diseases, Injuries, and Risk Factors Study (GBD) 2020 for 21 regions, including 204 countries and territories, by 5-year age group, sex, and year for individuals aged 15-95 years and older from 1990 to 2020. Based on the NDE, we quantified the population consuming harmful amounts of alcohol. FINDINGS The burden-weighted relative risk curves for alcohol use varied by region and age. Among individuals aged 15-39 years in 2020, the TMREL varied between 0 (95% uncertainty interval 0-0) and 0·603 (0·400-1·00) standard drinks per day, and the NDE varied between 0·002 (0-0) and 1·75 (0·698-4·30) standard drinks per day. Among individuals aged 40 years and older, the burden-weighted relative risk curve was J-shaped for all regions, with a 2020 TMREL that ranged from 0·114 (0-0·403) to 1·87 (0·500-3·30) standard drinks per day and an NDE that ranged between 0·193 (0-0·900) and 6·94 (3·40-8·30) standard drinks per day. Among individuals consuming harmful amounts of alcohol in 2020, 59·1% (54·3-65·4) were aged 15-39 years and 76·9% (73·0-81·3) were male. INTERPRETATION There is strong evidence to support recommendations on alcohol consumption varying by age and location. Stronger interventions, particularly those tailored towards younger individuals, are needed to reduce the substantial global health loss attributable to alcohol.

Abstract
AIMS The associations between low-density lipoprotein cholesterol (LDL-C) and the risk of cardiovascular disease (CVD) subtypes are not well established among the Japanese population. This study used longitudinal data from the Aichi Workers' Cohort Study to explore the association between LDL-C levels and the risk of coronary heart disease (CHD) and stroke subtypes. METHODS Pooled data of 8966 adults (7093men and 1903 women) who were recruited between (2002) and (2008) were used for the current analysis. Propensity scores for the LDL-C categories were generated using multinomial logistic regression. Hazard ratios (HRs) and 95% confidence intervals (CIs) were estimated from the inverse probability weighted Cox proportional hazards model for LDL-C category associations with risks of CHD, stroke subtypes, and CVD. RESULTS During a median follow-up of 12 years, 122 strokes (57 ischemic strokes, 25 intracerebral hemorrhage, and 40 unknown subtypes) and 82 cases of CHD were observed. LDL-C 160- mg/dL compared to LDL-C 100-119 mg/dL was positively and significantly associated with the risk of CHD (HR: 4.56; 95% CI: 1.91-10.9) but not with ischemic stroke (HR: 0.99; 95% CI: 0.44-2.22). LDL-C was inversely associated with the risk of intracerebral hemorrhage (P for trend=0.009). CONCLUSION In middle-aged Japanese workers, LDL-C was significantly and positively associated with CHD, but not with ischemic stroke. LDL-C was inversely significantly associated with intracerebral hemorrhage.

Abstract
INTRODUCTION Environmental toxicants such as chemical pollution have an enormous impact on the health of people and the planet. Emerging findings suggest that non-communicable diseases are linked to early and chronic environmental exposures. However, the rapid globalisation in developing countries, environmental change and the emergence, spread, persistence and severity of infectious diseases are not yet well understood. The aim of this study is to understand which environmental toxicants are commonly associated with infectious diseases in low-income and middle-income countries (LMICs). METHODS AND ANALYSIS A total of four electronic databases, MEDLINE through PubMed, Scopus, Web of Science and CENTRAL (the Cochrane Library) be searched to identify relevant studies and will be screened by two independent reviewers. The Cochrane risk of bias (ROB) tool for randomised control trials (RCTs) and ROB assessment tool for non-randomised studies for non-RCTs will be used to assess the ROB. A meta-analysis will be used to determine the pooled effect if we find out the included articles have similar environmental exposure, participant groups, study design and outcome measures. A narrative synthesis of the findings will be provided, along with summaries of the intervention effect. Heterogeneity between the studies will be assessed, and sensitivity analysis will be conducted based on study quality. ETHICS AND DISSEMINATION Findings will be summarised in a single manuscript. This review attempts to explore the pivotal role of environmental toxicants in predisposing, developing, persistent and severity of infectious diseases in LMICs. Findings from this study will highlight the effects of individual environmental toxicants' role on infectious disease outcomes for the early prevention and limit toxic exposure to guide individual, community, and occupational health policy for future strategies.

Abstract
Mass testing for COVID-19 infection is one of the core measures in tackling the global spread of the disease. Testing is vital to diagnose and estimate cases, attack rates and case fatality rates- critical data for policy-making. As COVID-19 continues to spread globally, the demand for more extensive laboratory testing and innovative technology increases. However, countries around the world have been struggling to keep up pace with the worldwide demand to expand testing strategy. The pandemic evolves, so does our knowledge and understanding of diagnostic tests of COVID-19. Here we aim to review major challenges related to COVID-19 diagnostic tests and future development. So, the ongoing urgency and demand for tests would certainly steer the rapid uptake of novel techniques, which in turn would boost our understanding of diagnostic tests for COVID-19.

Abstract
OBJECTIVE Diabetes poses serious health threats and economic burdens to patients, especially in low-income and middle-income countries (LMICs). This systematic review searches for non-pharmacological interventions for the prevention of type-2 diabetes mellitus (T2DM) among patients who are non-diabetic and pre-diabetic from LMICs. SETTINGS LMICs. PARTICIPANTS Adult population aged over 18 years without having diabetes. PRIMARY AND SECONDARY OUTCOMES Primary outcome is to measure the change in the incidence of T2DM. The secondary outcome is to measure changes in glycated haemoglobin (HbA1c) level, weight/body mass index (BMI), fasting glucose level and 2-hour glucose from baseline of the included randomised controlled trials. METHODS This review has been conducted following the standard systematic review guidelines. A total of six electronic databases including MEDLINE, Embase, the Cochrane Library, Web of Science, ClinicalTrials.gov and International Clinical Trials Registry Platform were searched in February 2021 using a comprehensive search strategy.Two sets of independent reviewers performed screening, risk of bias (ROB) assessment using the Cochrane ROB tool and data extraction. Narrative coalescence of selected articles was demonstrated using tables. No meta-analysis was performed due to the lack of homogenous intervention strategies and study settings. RESULT A total of five studies were included for the review with a combined population of 1734 from three countries. Three of the studies showed a significant reduction in T2DM incidence after the intervention of physical training and dietary modifications. Four of the studies also demonstrated a significant reduction of different secondary outcomes like weight, BMI, fasting and 2-hour plasma glucose and HbA1c. All the studies demonstrated a low ROB in most of the bias assessment domains with some unclear results in allocation concealments. CONCLUSIONS Emphasising non-pharmacological interventions for T2DM prevention can improve health outcomes and lessen the economic burdens, which will be of paramount importance in LMICs.

Global, regional, and national burden of hepatitis B, 1990–2019: a systematic analysis for the Global Burden of Disease Study 2019. Lancet Gastroenterol Hepatol 2022; 7:796-829. [PMID: 35738290 PMCID: PMC9349325 DOI: 10.1016/s2468-1253(22)00124-8] [Citation(s) in RCA: 176] [Impact Index Per Article: 88.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/10/2021] [Revised: 04/02/2022] [Accepted: 04/04/2022] [Indexed: 12/23/2022]
Abstract
Background Combating viral hepatitis is part of the UN Sustainable Development Goals (SDGs), and WHO has put forth hepatitis B elimination targets in its Global Health Sector Strategy on Viral Hepatitis (WHO-GHSS) and Interim Guidance for Country Validation of Viral Hepatitis Elimination (WHO Interim Guidance). We estimated the global, regional, and national prevalence of hepatitis B virus (HBV), as well as mortality and disability-adjusted life-years (DALYs) due to HBV, as part of the Global Burden of Diseases, Injuries, and Risk Factors Study (GBD) 2019. This included estimates for 194 WHO member states, for which we compared our estimates to WHO elimination targets. Methods The primary data sources were population-based serosurveys, claims and hospital discharges, cancer registries, vital registration systems, and published case series. We estimated chronic HBV infection and the burden of HBV-related diseases, defined as an aggregate of cirrhosis due to hepatitis B, liver cancer due to hepatitis B, and acute hepatitis B. We used DisMod-MR 2.1, a Bayesian mixed-effects meta-regression tool, to estimate the prevalence of chronic HBV infection, cirrhosis, and aetiological proportions of cirrhosis. We used mortality-to-incidence ratios modelled with spatiotemporal Gaussian process regression to estimate the incidence of liver cancer. We used the Cause of Death Ensemble modelling (CODEm) model, a tool that selects models and covariates on the basis of out-of-sample performance, to estimate mortality due to cirrhosis, liver cancer, and acute hepatitis B. Findings In 2019, the estimated global, all-age prevalence of chronic HBV infection was 4·1% (95% uncertainty interval [UI] 3·7 to 4·5), corresponding to 316 million (284 to 351) infected people. There was a 31·3% (29·0 to 33·9) decline in all-age prevalence between 1990 and 2019, with a more marked decline of 76·8% (76·2 to 77·5) in prevalence in children younger than 5 years. HBV-related diseases resulted in 555 000 global deaths (487 000 to 630 000) in 2019. The number of HBV-related deaths increased between 1990 and 2019 (by 5·9% [–5·6 to 19·2]) and between 2015 and 2019 (by 2·9% [–5·9 to 11·3]). By contrast, all-age and age-standardised death rates due to HBV-related diseases decreased during these periods. We compared estimates for 2019 in 194 WHO locations to WHO-GHSS 2020 targets, and found that four countries achieved a 10% reduction in deaths, 15 countries achieved a 30% reduction in new cases, and 147 countries achieved a 1% prevalence in children younger than 5 years. As of 2019, 68 of 194 countries had already achieved the 2030 target proposed in WHO Interim Guidance of an all-age HBV-related death rate of four per 100 000. Interpretation The prevalence of chronic HBV infection declined over time, particularly in children younger than 5 years, since the introduction of hepatitis B vaccination. HBV-related death rates also decreased, but HBV-related death counts increased as a result of population growth, ageing, and cohort effects. By 2019, many countries had met the interim seroprevalence target for children younger than 5 years, but few countries had met the WHO-GHSS interim targets for deaths and new cases. Progress according to all indicators must be accelerated to meet 2030 targets, and there are marked disparities in burden and progress across the world. HBV interventions, such as vaccination, testing, and treatment, must be strategically supported and scaled up to achieve elimination. Funding Bill & Melinda Gates Foundation.

Abstract
Background The population's mental and physical health worldwide are currently at risk due to the coronavirus pandemic. We evaluated the mental health status of the adolescents trapped indoors because of the precautionary restrictions and prolonged closure of the educational institutions. Method A cross-sectional study was conducted on adolescents from multiple urban and semi-urban areas of Bangladesh from 22 January to 3 February 2021. A self-reported online questionnaire containing questions regarding sociodemographic factors, home quarantine-related factors and mental health symptoms was distributed to collect data. Descriptive analysis, bivariate and multivariable logistic regressions were performed to measure the association of the variables. Cronbach's alpha was estimated to present the internal consistency of the scales. Results A total of 322 adolescents (aged 12–19) with a mean age of 16.00 years (SD = 1.84) responded to the invitation. 54.97% (n = 177) of them were male, and the participants were predominantly urban residents (87.27%, n = 281). We observed varying degrees of depression in 67.08%, anxiety in 49.38% and stress in 40.68% of the participants according to DASS-21. Age, sex, education, mother's occupation, total monthly income, playing sports, doing household chores, going out of home, watching television, using the internet, attending online classes, changing food habits, and communicating with friends had a positive significant association with mental health burdens. Conclusion Home quarantine has a noticeable adverse impact on the mental health of teenagers. Psychological evaluations and counselling via online and offline programs are essential to improve adolescents' declining mental health conditions.

Cost-Effectiveness of Population Screening Programs for Cardiovascular Diseases and Diabetes in Low- and Middle-Income Countries: A Systematic Review. Front Public Health 2022; 10:820750. [PMID: 35345509 PMCID: PMC8957212 DOI: 10.3389/fpubh.2022.820750] [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: 11/23/2021] [Accepted: 01/11/2022] [Indexed: 11/29/2022] Open
Abstract
Almost all low- and middle-income countries (LMICs) have instated a program to control and manage non-communicable diseases (NCDs). Population screening is an integral component of this strategy and requires a substantial chunk of investment. Therefore, testing the screening program for economic along with clinical effectiveness is essential. There is significant proof of the benefits of incorporating economic evidence in health decision-making globally, although evidence from LMICs in NCD prevention is scanty. This systematic review aims to consolidate and synthesize economic evidence of screening programs for cardiovascular diseases (CVD) and diabetes from LMICs. The study protocol is registered on PROSPERO (CRD42021275806). The review includes articles from English and Chinese languages. An initial search retrieved a total of 2,644 potentially relevant publications. Finally, 15 articles (13 English and 2 Chinese reports) were included and scrutinized in detail. We found 6 economic evaluations of interventions targeting cardiovascular diseases, 5 evaluations of diabetes interventions, and 4 were combined interventions, i.e., screening of diabetes and cardiovascular diseases. The study showcases numerous innovative screening programs that have been piloted, such as using mobile technology for screening, integrating non-communicable disease screening with existing communicable disease screening programs, and using community health workers for screening. Our review reveals that context is of utmost importance while considering any intervention, i.e., depending on the available resources, cost-effectiveness may vary—screening programs can be made universal or targeted just for the high-risk population.

Abstract
INTRODUCTION Urinary tract infection (UTI) is a frequently diagnosed infection in women and children. Treatments are often initiated with broad-spectrum antibiotics without performing any culture and sensitivity test. Inappropriate and empirical antimicrobial regimens and poor adherence to the drugs lead to the recurrence of the disease. Moreover, resistance against antibiotics in the urinary tract bacteria due to inadequate therapies is a more significant cause of concern. This systematic review will explore the different antimicrobial options for treating UTIs in children and compare their effectiveness. METHODS AND ANALYSIS Four electronic databases MEDLINE, Cochrane Central Register of Controlled Trials, Scopus and Web of Science will be searched in February 2022 to find relevant studies. After the initial screening by two independent review authors, the selected articles will go through the full-text evaluation to filter the inclusion criteria. Using an appropriate tool, the risk of bias will also be assessed by two independent review authors. The review results showing the treatment effects of different antimicrobials will be presented as a narrative synthesis, and a meta-analysis will be conducted if applicable. Assessment of heterogeneity between studies, assessment of publication bias, and sensitivity analysis will also be performed. ETHICS AND DISSEMINATION The study protocol of this systematic review has been approved by the institutional review board of North South University. The dissemination of the results will be conducted in the form of scientific publication in a peer-reviewed journal and presentations in different regional and international conferences.

Medicine (Baltimore) 2022; 101:e29030. [PMID: 35451407 PMCID: PMC8913098 DOI: 10.1097/md.0000000000029030] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/17/2022] [Accepted: 02/18/2022] [Indexed: 01/04/2023] Open
Abstract
BACKGROUND Advances in medical science coupled with increased people's income results an elevated average of life expectancy even in the resource poor countries. The growing number of aged population, however, has drawn little attention in health system discourse of low- and Middle-Income Countries (LMICs). Nevertheless, ensuring availability of appropriate service and properly trained and skilled health workforce is an absolute necessity for a functional geriatric and palliative healthcare. Given the lack of specialist geriatricians in LMICs contexts, there are other health workforce strategies that might be effective in building a proper health system response to this growing demand. Therefore, we aimed to identify and synthesize evidence on the existing health workforce-related strategies taken to provide geriatric and palliative care in LMICs. METHODS We will follow the recommendations provided by the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) checklist. Following the PRISMA guidelines, we will search the Medline/PubMed, Scopus, Web of Science and Cochrane database from January 2011 to December 2021 using a comprehensive search strategy. Two independent reviewers will screen the title and abstracts text using the specified inclusion and exclusion criteria. For the finally included articles, full manuscripts will be retrieved, and reviewers will appraise and extract data using standardized form independently. The third reviewer will resolve any disagreements appear in the process. The findings of the review be synthesized using the narrative synthesis approach to analyse descriptive quantitative and qualitative data. Furthermore, meta-analysis will be done provided that the data meet certain requirement as per Cochrane guideline. Rayyan software will be used to manage and synthesize data. Revman software will be used to do meta-analysis, if data support. RESULTS Findings of this review will be published in a peer-reviewed journal. CONCLUSION This systematic review will identify the existing effective strategies taken to provide geriatric and palliative care, in LMICs.

Diabetes mortality and trends before 25 years of age: an analysis of the Global Burden of Disease Study 2019. Lancet Diabetes Endocrinol 2022; 10:177-192. [PMID: 35143780 PMCID: PMC8860753 DOI: 10.1016/s2213-8587(21)00349-1] [Citation(s) in RCA: 40] [Impact Index Per Article: 20.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/21/2021] [Revised: 10/27/2021] [Accepted: 12/10/2021] [Indexed: 02/07/2023]
Abstract
BACKGROUND Diabetes, particularly type 1 diabetes, at younger ages can be a largely preventable cause of death with the correct health care and services. We aimed to evaluate diabetes mortality and trends at ages younger than 25 years globally using data from the Global Burden of Diseases, Injuries, and Risk Factors Study (GBD) 2019. METHODS We used estimates of GBD 2019 to calculate international diabetes mortality at ages younger than 25 years in 1990 and 2019. Data sources for causes of death were obtained from vital registration systems, verbal autopsies, and other surveillance systems for 1990-2019. We estimated death rates for each location using the GBD Cause of Death Ensemble model. We analysed the association of age-standardised death rates per 100 000 population with the Socio-demographic Index (SDI) and a measure of universal health coverage (UHC) and described the variability within SDI quintiles. We present estimates with their 95% uncertainty intervals. FINDINGS In 2019, 16 300 (95% uncertainty interval 14 200 to 18 900) global deaths due to diabetes (type 1 and 2 combined) occurred in people younger than 25 years and 73·7% (68·3 to 77·4) were classified as due to type 1 diabetes. The age-standardised death rate was 0·50 (0·44 to 0·58) per 100 000 population, and 15 900 (97·5%) of these deaths occurred in low to high-middle SDI countries. The rate was 0·13 (0·12 to 0·14) per 100 000 population in the high SDI quintile, 0·60 (0·51 to 0·70) per 100 000 population in the low-middle SDI quintile, and 0·71 (0·60 to 0·86) per 100 000 population in the low SDI quintile. Within SDI quintiles, we observed large variability in rates across countries, in part explained by the extent of UHC (r2=0·62). From 1990 to 2019, age-standardised death rates decreased globally by 17·0% (-28·4 to -2·9) for all diabetes, and by 21·0% (-33·0 to -5·9) when considering only type 1 diabetes. However, the low SDI quintile had the lowest decline for both all diabetes (-13·6% [-28·4 to 3·4]) and for type 1 diabetes (-13·6% [-29·3 to 8·9]). INTERPRETATION Decreasing diabetes mortality at ages younger than 25 years remains an important challenge, especially in low and low-middle SDI countries. Inadequate diagnosis and treatment of diabetes is likely to be major contributor to these early deaths, highlighting the urgent need to provide better access to insulin and basic diabetes education and care. This mortality metric, derived from readily available and frequently updated GBD data, can help to monitor preventable diabetes-related deaths over time globally, aligned with the UN's Sustainable Development Targets, and serve as an indicator of the adequacy of basic diabetes care for type 1 and type 2 diabetes across nations.

Abstract
Background The dementia care policy in Japan emphasizes the views of people living with dementia in care planning. An exploration of the everyday wishes of older people living with dementia can help clarify their priorities and assist in improving dementia care. This study aimed to explore the everyday wishes of older people living with dementia in Japan. Methods This qualitative study was conducted in Aichi prefecture in Japan. Older people with mild to moderate dementia were considered for inclusion. Participants were recruited from a dementia outpatient clinic. In-depth interviews were conducted with 36 participants in the same dementia outpatient clinic from January to October 2019. Audio-recorded interviews were transcribed verbatim. Inductive content analysis was carried out to analyze the data. Findings Participants expressed their everyday wishes within five themes (desire of being connected, freedom to decide, involvement in activities, status quo, and self-reliance). Older people living with dementia loved the connection with their family and wanted to have an enjoyable life by engaging in several activities without others’ interference. They desired to maintain the status quo and not be a burden to others. Conclusions This study provides evidence on the everyday wishes of people living with dementia. Identified wishes are mostly on emotional aspects of their daily lives. The findings of our study might help provide care for the people living with dementia considering their wishes. Further exploration, including people with severe dementia, is needed. Supplementary Information The online version contains supplementary material available at 10.1186/s12913-022-07606-1.

Global, regional, and national sex differences in the global burden of tuberculosis by HIV status, 1990-2019: results from the Global Burden of Disease Study 2019. THE LANCET. INFECTIOUS DISEASES 2022; 22:222-241. [PMID: 34563275 PMCID: PMC8799634 DOI: 10.1016/s1473-3099(21)00449-7] [Citation(s) in RCA: 37] [Impact Index Per Article: 18.5] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 02/26/2021] [Revised: 05/21/2021] [Accepted: 07/15/2021] [Indexed: 02/07/2023]
Abstract
BACKGROUND Tuberculosis is a major contributor to the global burden of disease, causing more than a million deaths annually. Given an emphasis on equity in access to diagnosis and treatment of tuberculosis in global health targets, evaluations of differences in tuberculosis burden by sex are crucial. We aimed to assess the levels and trends of the global burden of tuberculosis, with an emphasis on investigating differences in sex by HIV status for 204 countries and territories from 1990 to 2019. METHODS We used a Bayesian hierarchical Cause of Death Ensemble model (CODEm) platform to analyse 21 505 site-years of vital registration data, 705 site-years of verbal autopsy data, 825 site-years of sample-based vital registration data, and 680 site-years of mortality surveillance data to estimate mortality due to tuberculosis among HIV-negative individuals. We used a population attributable fraction approach to estimate mortality related to HIV and tuberculosis coinfection. A compartmental meta-regression tool (DisMod-MR 2.1) was then used to synthesise all available data sources, including prevalence surveys, annual case notifications, population-based tuberculin surveys, and tuberculosis cause-specific mortality, to produce estimates of incidence, prevalence, and mortality that were internally consistent. We further estimated the fraction of tuberculosis mortality that is attributable to independent effects of risk factors, including smoking, alcohol use, and diabetes, for HIV-negative individuals. For individuals with HIV and tuberculosis coinfection, we assessed mortality attributable to HIV risk factors including unsafe sex, intimate partner violence (only estimated among females), and injection drug use. We present 95% uncertainty intervals for all estimates. FINDINGS Globally, in 2019, among HIV-negative individuals, there were 1·18 million (95% uncertainty interval 1·08-1·29) deaths due to tuberculosis and 8·50 million (7·45-9·73) incident cases of tuberculosis. Among HIV-positive individuals, there were 217 000 (153 000-279 000) deaths due to tuberculosis and 1·15 million (1·01-1·32) incident cases in 2019. More deaths and incident cases occurred in males than in females among HIV-negative individuals globally in 2019, with 342 000 (234 000-425 000) more deaths and 1·01 million (0·82-1·23) more incident cases in males than in females. Among HIV-positive individuals, 6250 (1820-11 400) more deaths and 81 100 (63 300-100 000) more incident cases occurred among females than among males in 2019. Age-standardised mortality rates among HIV-negative males were more than two times greater in 105 countries and age-standardised incidence rates were more than 1·5 times greater in 74 countries than among HIV-negative females in 2019. The fraction of global tuberculosis deaths among HIV-negative individuals attributable to alcohol use, smoking, and diabetes was 4·27 (3·69-5·02), 6·17 (5·48-7·02), and 1·17 (1·07-1·28) times higher, respectively, among males than among females in 2019. Among individuals with HIV and tuberculosis coinfection, the fraction of mortality attributable to injection drug use was 2·23 (2·03-2·44) times greater among males than females, whereas the fraction due to unsafe sex was 1·06 (1·05-1·08) times greater among females than males. INTERPRETATION As countries refine national tuberculosis programmes and strategies to end the tuberculosis epidemic, the excess burden experienced by males is important. Interventions are needed to actively communicate, especially to men, the importance of early diagnosis and treatment. These interventions should occur in parallel with efforts to minimise excess HIV burden among women in the highest HIV burden countries that are contributing to excess HIV and tuberculosis coinfection burden for females. Placing a focus on tuberculosis burden among HIV-negative males and HIV and tuberculosis coinfection among females might help to diminish the overall burden of tuberculosis. This strategy will be crucial in reaching both equity and burden targets outlined by global health milestones. FUNDING Bill & Melinda Gates Foundation.

The global burden of adolescent and young adult cancer in 2019: a systematic analysis for the Global Burden of Disease Study 2019. Lancet Oncol 2022; 23:27-52. [PMID: 34871551 PMCID: PMC8716339 DOI: 10.1016/s1470-2045(21)00581-7] [Citation(s) in RCA: 87] [Impact Index Per Article: 43.5] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/05/2021] [Revised: 09/28/2021] [Accepted: 09/29/2021] [Indexed: 02/07/2023]
Abstract
BACKGROUND In estimating the global burden of cancer, adolescents and young adults with cancer are often overlooked, despite being a distinct subgroup with unique epidemiology, clinical care needs, and societal impact. Comprehensive estimates of the global cancer burden in adolescents and young adults (aged 15-39 years) are lacking. To address this gap, we analysed results from the Global Burden of Diseases, Injuries, and Risk Factors Study (GBD) 2019, with a focus on the outcome of disability-adjusted life-years (DALYs), to inform global cancer control measures in adolescents and young adults. METHODS Using the GBD 2019 methodology, international mortality data were collected from vital registration systems, verbal autopsies, and population-based cancer registry inputs modelled with mortality-to-incidence ratios (MIRs). Incidence was computed with mortality estimates and corresponding MIRs. Prevalence estimates were calculated using modelled survival and multiplied by disability weights to obtain years lived with disability (YLDs). Years of life lost (YLLs) were calculated as age-specific cancer deaths multiplied by the standard life expectancy at the age of death. The main outcome was DALYs (the sum of YLLs and YLDs). Estimates were presented globally and by Socio-demographic Index (SDI) quintiles (countries ranked and divided into five equal SDI groups), and all estimates were presented with corresponding 95% uncertainty intervals (UIs). For this analysis, we used the age range of 15-39 years to define adolescents and young adults. FINDINGS There were 1·19 million (95% UI 1·11-1·28) incident cancer cases and 396 000 (370 000-425 000) deaths due to cancer among people aged 15-39 years worldwide in 2019. The highest age-standardised incidence rates occurred in high SDI (59·6 [54·5-65·7] per 100 000 person-years) and high-middle SDI countries (53·2 [48·8-57·9] per 100 000 person-years), while the highest age-standardised mortality rates were in low-middle SDI (14·2 [12·9-15·6] per 100 000 person-years) and middle SDI (13·6 [12·6-14·8] per 100 000 person-years) countries. In 2019, adolescent and young adult cancers contributed 23·5 million (21·9-25·2) DALYs to the global burden of disease, of which 2·7% (1·9-3·6) came from YLDs and 97·3% (96·4-98·1) from YLLs. Cancer was the fourth leading cause of death and tenth leading cause of DALYs in adolescents and young adults globally. INTERPRETATION Adolescent and young adult cancers contributed substantially to the overall adolescent and young adult disease burden globally in 2019. These results provide new insights into the distribution and magnitude of the adolescent and young adult cancer burden around the world. With notable differences observed across SDI settings, these estimates can inform global and country-level cancer control efforts.

Abstract
INTRODUCTION Hypertension is a major risk factor for cardiovascular diseases. In 2015, over 1.13 billion individuals worldwide had hypertension. Globally, it results in 10.8 million deaths every year. Around half of the individuals do not continue treatment with medicine to control blood pressure. Physical activity, a non-pharmacological option of treatment, reduces blood pressure. We aim in this research to examine the effect of leisure-time physical activity in controlling blood pressure. METHODS AND ANALYSIS We will follow the Preferred Reporting Items for Systematic Reviews and Meta-Analyses to conduct this study. We will perform a systematic search in Medline/PubMed, Embase, Scopus, Web of Science, Physical Education Index (ProQuest) and CENTRAL (the Cochrane Library). Both experimental and observational studies will be included. The study population would be people with hypertension. Two reviewers will perform screening of the articles, bias assessment and data extraction independently. We will use the Joanna Briggs Institute Critical Appraisal Tools to assess the risk of bias. We will conduct a meta-analysis if it is applicable. ETHICS AND DISSEMINATION The results will be published in peer-reviewed journals and presented at relevant scientific seminars and conferences.

Abstract
Background After the first detection in November 2019, SARS-CoV-2 has spread rapidly over the continents and started the pandemic of the millennium. In addition to several novels and repurposed monoclonal antibodies (mAbs) as a therapeutic option against COVID-19, scientists from across the world have developed several candidate vaccines, developed mainly targeting the Wuhan strain, with very promising results to combat this pandemic. Unfortunately like any RNA viruses, SARS CoV-2 has also gone through the accumulation of hundreds and thousands of mutations in their genome lead to the development of several variants of concerns (VOC) and variants of interests (VOI), resulting in increased transmissibility and virulence of the virus, along with their capacity to escape cross-protection. Seemingly, the main hindrance of containing this pandemic right now is the effectiveness of currently available vaccines and mAbs against newly emerging variants. Therefore, it is important to monitor variants epidemiology, transmission dynamics, clinical characteristics, as well as their immune evasion capacity to implement appropriate vaccine strategy and other containment measures. Body In this review, we tried to focus on variants characteristics and to what extent they can escape immunity, provided by both available vaccinated sera and convalescent sera. A stringent literature review was performed using various databases, mentioned in the methodology portion. The current geographical distribution of these variants of SARS CoV-2 has been presented using a heat map. Findings from published articles comparing these variants, in terms of genome epidemiology, transmissibility, viral load dynamics, and association with different waves have been described briefly. Due strength was given while describing variants neutralization potency against current vaccines, mAbs, and also against convalescent sera. Data from both clinical trials and in vitro/ex-vivo studies have been discussed here. Comparative findings from several articles were brought into one concise paper. After careful reviewing of all the available data, it was clear that, without hesitation, we should strengthen our vaccination strategy, because the severity of COVID 19 is reasonably lower, irrespective of variants and vaccine used. Conclusion We hope that many falsified myths and beliefs regarding vaccine immunity and emerging variants will be clarified in light of this available evidence, which we summarized in our paper.

Abstract
Mental health is a significant factor for a sound and productive life; nevertheless, mental disorders do not often receive adequate research attention and are not addressed as a serious public health issue in countries such as Bangladesh. Part 1 of this two-part profile describes the current situation of mental health in Bangladesh in its wider sociocultural context, outlining existing policies and highlighting mental illness as a neglected healthcare problem in the country using a narrative synthesis method. The prevalence of mental disorders is very high and augmented in nature among different population groups in Bangladesh. A lack of public mental health facilities, scarcity of skilled mental health professionals, insufficient financial resource distribution, inadequately stewarded mental health policies and stigma contribute to making current mental healthcare significantly inadequate in Bangladesh. The country has few community care facilities for psychiatric patients. Furthermore, the current mental health expenditure by the Bangladeshi government is only 0.44% of the total health budget. Less than 0.11% of the population has access to free essential psychotropic medications.

Abstract
BACKGROUND Regularly updated data on stroke and its pathological types, including data on their incidence, prevalence, mortality, disability, risk factors, and epidemiological trends, are important for evidence-based stroke care planning and resource allocation. The Global Burden of Diseases, Injuries, and Risk Factors Study (GBD) aims to provide a standardised and comprehensive measurement of these metrics at global, regional, and national levels. METHODS We applied GBD 2019 analytical tools to calculate stroke incidence, prevalence, mortality, disability-adjusted life-years (DALYs), and the population attributable fraction (PAF) of DALYs (with corresponding 95% uncertainty intervals [UIs]) associated with 19 risk factors, for 204 countries and territories from 1990 to 2019. These estimates were provided for ischaemic stroke, intracerebral haemorrhage, subarachnoid haemorrhage, and all strokes combined, and stratified by sex, age group, and World Bank country income level. FINDINGS In 2019, there were 12·2 million (95% UI 11·0-13·6) incident cases of stroke, 101 million (93·2-111) prevalent cases of stroke, 143 million (133-153) DALYs due to stroke, and 6·55 million (6·00-7·02) deaths from stroke. Globally, stroke remained the second-leading cause of death (11·6% [10·8-12·2] of total deaths) and the third-leading cause of death and disability combined (5·7% [5·1-6·2] of total DALYs) in 2019. From 1990 to 2019, the absolute number of incident strokes increased by 70·0% (67·0-73·0), prevalent strokes increased by 85·0% (83·0-88·0), deaths from stroke increased by 43·0% (31·0-55·0), and DALYs due to stroke increased by 32·0% (22·0-42·0). During the same period, age-standardised rates of stroke incidence decreased by 17·0% (15·0-18·0), mortality decreased by 36·0% (31·0-42·0), prevalence decreased by 6·0% (5·0-7·0), and DALYs decreased by 36·0% (31·0-42·0). However, among people younger than 70 years, prevalence rates increased by 22·0% (21·0-24·0) and incidence rates increased by 15·0% (12·0-18·0). In 2019, the age-standardised stroke-related mortality rate was 3·6 (3·5-3·8) times higher in the World Bank low-income group than in the World Bank high-income group, and the age-standardised stroke-related DALY rate was 3·7 (3·5-3·9) times higher in the low-income group than the high-income group. Ischaemic stroke constituted 62·4% of all incident strokes in 2019 (7·63 million [6·57-8·96]), while intracerebral haemorrhage constituted 27·9% (3·41 million [2·97-3·91]) and subarachnoid haemorrhage constituted 9·7% (1·18 million [1·01-1·39]). In 2019, the five leading risk factors for stroke were high systolic blood pressure (contributing to 79·6 million [67·7-90·8] DALYs or 55·5% [48·2-62·0] of total stroke DALYs), high body-mass index (34·9 million [22·3-48·6] DALYs or 24·3% [15·7-33·2]), high fasting plasma glucose (28·9 million [19·8-41·5] DALYs or 20·2% [13·8-29·1]), ambient particulate matter pollution (28·7 million [23·4-33·4] DALYs or 20·1% [16·6-23·0]), and smoking (25·3 million [22·6-28·2] DALYs or 17·6% [16·4-19·0]). INTERPRETATION The annual number of strokes and deaths due to stroke increased substantially from 1990 to 2019, despite substantial reductions in age-standardised rates, particularly among people older than 70 years. The highest age-standardised stroke-related mortality and DALY rates were in the World Bank low-income group. The fastest-growing risk factor for stroke between 1990 and 2019 was high body-mass index. Without urgent implementation of effective primary prevention strategies, the stroke burden will probably continue to grow across the world, particularly in low-income countries.

Abstract
OBJECTIVES The burden of hypertension is increasing in low-income countries, including Ethiopia. Obesity is widely known to be associated with hypertension, but different anthropometric indices of obesity might differ in association with hypertension, which is largely unknown in northern Ethiopia. DESIGN Data from our previous cross-sectional epidemiological survey were statistically analysed. SETTING Public employees in the regional capital city in northern Ethiopia. PARTICIPANTS The data of 1380 participants (823 men and 557 non-pregnant women) aged 25 and 64 years were analysed. OUTCOME MEASURES The presence of hypertension was the outcome measure and multivariable-adjusted logistic regression analyses were used to investigate the association of body mass index (BMI), waist circumference, and waist-hip ratio in men and women separately. The area under the curve (AUC) for three anthropometric indices for discriminating hypertension was also obtained. Separate analyses were conducted for waist circumference and waist-hip ratio analyses further adjusted for BMI. RESULTS BMI was linearly associated with hypertension in men (OR for 1 SD increase in BMI 1.45, p=0.001) and women (OR for 1 SD increase in BMI 1.41, p=0.01). The association of waist circumference was independent of BMI both in men (OR for 1 SD increase in waist circumference: 1.74, p=0.002) and women (OR for 1 SD increase in waist circumference: 1.57, p=0.029). The association of waist-hip ratio with hypertension adjusted for BMI was significant in men (OR for 1 SD increase in the waist-hip ratio: 1.46, p<0.001), but was weak and non-significant in women. The AUC for BMI was 0.64 in men and 0.67 in women, while AUC for waist circumference was 0.69 both in men and women. CONCLUSIONS Waist circumference was associated with hypertension independent of BMI among public employees in northern Ethiopia.

Abstract
INTRODUCTION Tuberculosis (TB) continues to be a significant health burden, most commonly affecting the lungs and referred to as pulmonary TB (PTB). Diagnostic techniques of PTB primarily rely on expectorated sputum samples. However, the diagnostic yields are often hindered due to insufficient volume and quality of the sputum specimens. Moreover, some individuals are unable to provide sputum samples due to scanty sputum production or difficulty in coughing up and require an invasive procedure to obtain a respiratory sample, such as bronchoscopic or gastric aspiration. Thus, challenges in the acquisition of respiratory specimens warrant an alternate specimen. Therefore, this systematic review aims to evaluate the diagnostic accuracy of a stool specimen for the diagnosis of PTB in adults. METHODS AND ANALYSIS We will search MEDLINE (Ovid), Embase (Ovid), Web of Science and Cochrane database from inception to April 2021 using a comprehensive search strategy. Two reviewers will independently perform screening, data extraction and quality assessment. The risk of bias assessment and applicability of results of eligible studies will be performed using the Quality of Diagnostic Accuracy Studies-2 tool. Bivariate random-effects models will be performed to calculate pooled sensitivity, specificity, positive likelihood ratio and negative likelihood ratio and diagnostic odds ratio along with 95% CI of stool specimen for each reported diagnostic method against any of the reference standard test (ie, mycobacterial culture or smear microscopy or Xpert assay using respiratory specimens). Heterogeneity between studies will be assessed by I2 statistics and Q statistic of the χ2 test. ETHICS AND DISSEMINATION The results will be disseminated through publishing in a peer-reviewed medical journal and public presentations in relevant national and international conferences. As this is a systematic review of publicly available data, ethics approval is not required. PROSPERO REGISTRATION NUMBER CRD42021245203.

Implementation of advance care planning amid the COVID-19 crisis: A narrative review and synthesis. Geriatr Gerontol Int 2021; 21:779-787. [PMID: 34318579 PMCID: PMC8444945 DOI: 10.1111/ggi.14237] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/26/2021] [Revised: 06/13/2021] [Accepted: 06/28/2021] [Indexed: 12/02/2022]
Abstract
Advance care planning is considered an important issue in end‐of‐life care for older adults. The ongoing COVID‐19 pandemic has interrupted the healthcare system and end‐of‐life care tremendously. This review aimed to explore available articles on advance care planning amid the pandemic and analyze qualitatively. PubMed and Google Scholar were searched on February 2021 using the relevant keywords. Retrieved articles were screened applying inclusion criteria. Any article describing advance care planning during the COVID‐19 era was included. A qualitative content analysis was conducted. In total, 20 articles incorporating 5542 participants from five countries were included. Among the articles, eight were primary studies and the rest were perspective papers or secondary analysis. From the qualitative content analysis six major themes emerged namely palliative care, lack of coordination among acute care, hospital palliative care, and long‐term care, community‐based advance care planning, real‐time dissemination of scientific information on the regional pandemic situation, online system and legislation. The COVID‐19 pandemic had decreased the uptake of advance care planning. Findings of the review suggested simplification of the procedure regarding advance care planning, implementation of community‐based advance care planning and utilization of online resources to enhance the process.

Job satisfaction among physicians providing health care to the elderly in Japan: a qualitative study. Psychogeriatrics 2021; 21:311-316. [PMID: 33598980 DOI: 10.1111/psyg.12668] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/16/2020] [Revised: 12/22/2020] [Accepted: 02/01/2021] [Indexed: 12/01/2022]
Abstract
BACKGROUND Physicians' job satisfaction plays an important role in service delivery. Japan is a country with a higher number of elderly people and their medical care is a crucial issue. To date, no study has been conducted on the job satisfaction of geriatricians serving the elderly in Japan. This study aims to explore the job satisfaction and motivation of physicians providing health care to the elderly working at different hospitals in Japan. METHODS In-depth interview of 23 geriatric physicians was conducted and data were coded and analysed. Qualitative content analysis was conducted to identify the response themes. RESULTS Three major themes emerged from the analysis and they are: satisfaction as a primary care provider, career development, and suitable communication with patients. Geriatric physicians enjoy their work with inter-professional collaboration and are satisfied to provide primary health care to elderly people. Geriatrics is a very promising career to them and they enjoy the communication and empathetic doctor-patient relationship in their service. CONCLUSIONS Japanese physicians providing health care to the elderly are enjoying their work due to a suitable environment, multi-professional collaboration, work-life balance, and patient-doctor relationship.

Abstract
Ageism in health-care services is a cardinal public health concern in geriatric health. It is important to know the types and extent of discrimination experienced by elderly individuals while seeking health care. This systematic review aimed to explore the available research to identify discrimination of elderly individuals in health-care services. MEDLINE through PubMed, Web of Science, PsycInfo, and Cochrane Database were searched by using a comprehensive search strategy in September 2020 with no limitation in the year of publication and types of publication. Articles published in English focusing on disparities in health-care service among the elderly were included. Two independent authors screened, extracted, and assessed the quality of data using the Joanna Briggs Institute Critical Appraisal Tool. A narrative synthesis was conducted followed by qualitative content analysis to identify themes from the extracted outcomes of the included studies. Of 3117 articles retrieved from the initial search, 21 articles were included. A total of 611 608 participants from 38 countries in four geographic regions were reported. Articles were published between 2003 and 2020. Most of the studies (n = 19) were cross-sectional in design, and the remaining two studies were qualitative. Major themes of discrimination were age-related discrimination, racial discrimination, gender discrimination, wealth-related discrimination, and technology-related discrimination. This systematic review identified the major perspectives on disparities faced by the elderly in accessing health services. There is a huge research gap on this issue. Specific strategies should be incorporated to address the varying types of discrimination experienced by elderly individuals.

Abstract
Inhaled fluticasone is used in asthma for long duration. However, it's adverse effect on glycaemia is debatable. This study observed the outcome of inhaled fluticasone in asthma patients. A cross sectional comparative study was conducted among the normoglycaemic asthma patients aged 18 years and above attending outpatient department of Internal Medicine and Respiratory Medicine department of Bangabandhu Sheikh Mujib Medical University, Dhaka, Bangladesh from June 2017 to May 2018. Study group were getting inhaled fluticasone for minimum three months whereas comparative group were not on any steroids. Each group had 35 eligible participants (n=70). Spirometry and plasma glucose at fasting and 2-hour after 75gm oral glucose intake were measured along with HbA1c%. Statistical analysis was done using SPSS 21.0. In study group mean plasma glucose at fasting was 5.27±0.48mmol/L, 2-hour after 75gm oral glucose was 6.04±1.21mmol/L and mean of HbA1c was 5.57±0.41% whereas in comparative group these were5.17±0.59mmol/L, 5.69±1.09mmol/L, 5.47±0.40% respectively (p=0.25, 0.20, 0.75 respectively). There was no specific co-relation between duration of use of fluticasone inhaler and glycaemic parameters like plasma glucose at fasting, 2-hour after 75gm oral glucose and HbA1c% (r=0.016, p=0.46; r=0.015, p=0.47; r=0.019, p=0.42 respectively). Use of inhaled fluticasone for 3months or more has insignificant effect on plasma glucose levels of asthma patients. Duration of use of inhaled fluticasone has no specific correlation with plasma glucose and HbA1c values.

Abstract
Background As evidence is mounting regarding irrational and often unnecessary use of antibiotics during the COVID-19 pandemic a cross-sectional Point Prevalence Survey (PPS) (in accordance with WHO guideline) was conducted across COVID-19 dedicated wards in Dhaka Medical College and Hospital (DMCH). Methodology Antibiotic usage data were collected from 193 patients at different COVID-19 dedicated wards at DMCH on 11 June 2020. Comparisons in antibiotic usage were made between different groups using Pearson chi-square and Fisher's exact test. Result Findings reveal all surveyed patients (100%) were receiving at least one antibiotic with 133 patients (68.91%) receiving multiple antibiotics. Overall, patients presenting with the severe disease received more antibiotics. Third-generation cephalosporins (i.e. ceftriaxone) (53.8%), meropenem (40.9%), moxifloxacin (29.5%), and doxycycline (25.4%) were the four most prescribed antibiotics among surveyed patients. Diabetes mellitus (DM) was independently associated with multiple antibiotic prescribing. Abnormal C-reactive protein (CRP) and serum d-dimer were linked with higher odds of multiple antibiotic prescribing among study patients. Conclusion Prevalence of multiple antibiotic prescriptions was high among severely ill patients and those with abnormal CRP and d-dimer levels. Data regarding the quality of antibiotic prescribing were lacking.

Abstract
INTRODUCTION The disease burden caused by type 2 diabetes mellitus is a prime public health concern. The prevalence and rate of deaths from diabetes mellitus in low- and middle-income countries (LMICs) are higher than the high-income countries. Increased physical activity and a balanced diet are essential and successful measures to prevent the onset of diabetes mellitus. This systematic review aims to explore the available non-pharmacological approaches for the prevention of type 2 diabetes mellitus in LMICs. METHODS AND ANALYSIS Six online databases will be explored to get related randomized controlled trials (RCTs) published in English from inception to September 2020, and two coders will independently screen, identify studies, extract data, and assess the risk of bias in each article. The searched articles will be included by applying specific inclusion and exclusion criteria. Joanna Briggs Institute's tool for RCTs will be used for appraising the trials critically. Narrative synthesis and pooled effect of the interventions will be demonstrated. A meta-analysis will be conducted using the random-effects model if assumptions are fulfilled. DISCUSSION This review is an attempt to explore the available non-pharmacological approaches for the prevention of type 2 diabetes mellitus in LMICs. Findings from the review will highlight effective non-pharmacological measures for the prevention of type 2 diabetes mellitus to guide policy for future strategies. SYSTEMATIC REVIEW REGISTRATION The review protocol has been registered ( CRD42020191507 ).

Abstract
Several published reports have described a possible association between Guillain-Barré syndrome (GBS) and severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) infection. This systematic review aimed to summarize and meta-analyze the salient features and prognosis of SARS-CoV-2-associated GBS. We searched the PubMed (Medline), Web of Science and Cochrane databases for articles published between 01 January 2020 and 05 August 2020 using SARS-CoV-2 and GBS-related keywords. Data on sociodemographic characteristics, antecedent symptoms, clinical, serological and electrophysiological features, and hospital outcomes were recorded. We included 45 articles from 16 countries reporting 61 patients with SARS-CoV-2-associated GBS. Most (97.7%) articles were from high- and upper-middle-income countries. Forty-two (68.9%) of the patients were male; median (interquartile range) age was 57 (49-70) years. Reverse transcriptase polymerase chain reaction for SARS-CoV-2 was positive in 90.2% of patients. One report of SARS-CoV-2-associated familial GBS was found which affected a father and daughter of a family. Albuminocytological dissociation in cerebrospinal fluid was found in 80.8% of patients. The majority of patients (75.5%) had a demyelinating subtype of GBS. Intravenous immunoglobulin and plasmapheresis were given to 92.7% and 7.3% of patients, respectively. Around two-thirds (65.3%) of patients had a good outcome (GBS-disability score ≤ 2) on discharge from hospital. Two patients died in hospital. SARS-CoV-2-associated GBS mostly resembles the classical presentations of GBS that respond to standard treatments. Extensive surveillance is required in low- and lower-middle-income countries to identify and report similar cases/series. Further large-scale case-control studies are warranted to strengthen the current evidence. PROSPERO Registration Number CRD42020201673.

Abstract
Smoking remains one of the leading risk factors contributing to the global burden of disease. Sub-optimal implementation of evidence-based tobacco control and smoking cessation practice is a major challenge despite a substantial evidence base for interventions to increase smoking cessation globally. We aim to develop an Evidence and Gap Map (EGM) to collate the existing evidence and identify the gap in research on interventions to increase smoking cessation worldwide. A conceptual framework was developed followed by the formulation of a search strategy with key search terms and search period (1970 – date of search). The search will be conducted in relevant bibliographic databases (e.g. MEDLINE, Embase, SCOPUS), systematic reviews databases (e.g. Cochrane Library, Joanna Briggs systematic reviews, EPPI-Reviewer) and impact evaluation databases (e.g. 3ie Impact Evaluation repository and Cochrane tobacco addiction group specialized register) with support from a research librarian. Subsequently, two coders will screen and retrieve systematic reviews and individual impact evaluation studies. The adapted SURE (Supporting the Use of Research Evidence) checklist will be used to evaluate the quality of the included systematic reviews. A narrative synthesis from the systematic review findings and line listing of the impact evaluations will form the basis of this EGM. The EGM report will be presented in an interactive visual format. The proposed EGM will organise the pieces of evidence generated in systematic reviews and impact evaluations on smoking cessation interventions and identify the current research gaps, if any. The findings will inform evidence-based practice and future research.

Abstract
BACKGROUND Tobacco consumption causes almost 638,000 premature deaths per year in India. This study sought to examine the prevalence and determinants of tobacco use among men in India. METHODS We analyzed data from the fourth round of the National Family Health Survey in India. These nationally representative cross-sectional sample data were collected from January 20, 2015, to December 4, 2016. A total of 112,122 men aged 15-54 years were included in this study. Primary outcomes were tobacco use categorized into smoking, smokeless, any tobacco, and both smoked and smokeless tobacco use. Complex survey design and sampling weights were applied in both the descriptive analyses and logistic regression models. We present the findings using odds ratios. RESULTS The prevalence of tobacco use among men in India for the studied period was 45.5% (95% CI 44.9-46.1), smoking was 24.6% (95% CI 24.1-25.1), smokeless tobacco use was 29.1% (95% CI 28.6-29.6), and both smoked and smokeless tobacco use was 8.4% (95% CI 8.1-8.7). The prevalence of tobacco use among men was higher among the elderly, separated/divorced/widowed individuals, those with lower education and wealth status, alcohol consumers, manual workers, and residents of the northeast region. Multivariate analysis showed that age, lower education, occupation, region, alcohol consumption, separated/divorced/widowed status, and economic status were substantially associated with tobacco use among Indian men. CONCLUSIONS Innovative and cost-effective strategies targeting high-risk groups are crucial to curbing the tobacco epidemic in India. Anti-smoking campaigns should also focus on mitigating alcohol abuse. Reducing tobacco marketing and implementing formal education about the dangers of tobacco use, progressive taxing, packaging, and labeling of tobacco products and price strategies should be harmonized in legal provisions.

Abstract
BACKGROUND Caesarean delivery on maternal request (CDMR) is considered a significant contributor to the unprecedented increase in caesarean deliveries (CDs) for nonclinical reasons. Current literature lacks a reliable assessment of the rate of CDMR, which hinders the planning and delivery of appropriate interventions for reducing CDMR rates. OBJECTIVES To conduct a systematic review of the literature and meta-regression to explore the global incidence of CDMR. SEARCH STRATEGY PubMed, Embase, CINAHL, Medline, Google scholar and grey literature were searched from January 1985 to May 2019. SELECTION CRITERIA Observational studies that report CDMR data were included. We excluded non-English articles, case notes, editorial reviews and articles reporting elective CDs from pregnancy risk factors. DATA COLLECTION AND ANALYSIS Two reviewers independently conducted the screening and quality appraisal using a validated tool. The weighted average of CDMR over total deliveries (absolute proportion) and by total CDs (relative proportion) were generated. Quality-effects meta-regression was used to explain the variability of the CDMR estimates by moderators, including study methodology and demography of study participants. MAIN RESULTS We identified 31 articles from 14 countries that include 5 million total births. The absolute proportion of CDMR varies between 0.2 and 42.0%, with significant variations across studies and subgroups. The economic status of the country and study year together explained 84% of the absolute and 76% of the relative proportion of CDMR variation. CONCLUSIONS An appropriate reporting of CDMR should be a key priority in maternal health policies and practices. TWEETABLE ABSTRACT Globally, the proportion of maternal requested caesarean delivery has mostly been influenced by the economic status of the country.
