Acceptability and use of HIV self-testing among young people in sub-Saharan Africa: a mixed methods systematic review

BackgroundYoung people (YP) are disproportionately affected by the HIV pandemic in sub-Saharan Africa (SSA), but testing rates remain low despite global targets of testing 95% of people with HIV infection by 2030. HIV self-testing (HIVST) has been recently introduced to reach high-risk population groups such as these. Thus, synthesis of emerging evidence on the acceptability and use of HIVST among YP in SSA is needed so that comprehensive information can be generated to inform policy and practice.MethodsWe employed a mixed methods systematic review of quantitative and qualitative literature reporting on HIVST among YP involving any design and published in English by 31st of October 2023. The review synthesized quantitative evidence on acceptability and use of HIVST, and qualitative evidence on perspectives of YP about HIVST. We searched databases of published articles (e.g. MEDLINE, CINAHL) and Gray literature sources (e.g. Google, Google Scholar). The concepts for the search included self-testing, HIV/AIDS, and countries in SSA. Two authors independently screened, retrieved full-text, and assessed quality of the studies.ResultsA total of 4150 studies were retrieved and 32 studies were finally included in the review. Acceptability of HIVST computed from a single item asking YP on their preference or willingness or demand for HIVST was moderate (34–67%) to high (≥ 67%) among YP in SSA. Nine of the fourteen studies that reported on acceptability found high acceptability of HIVST. Use of HIVST ranged from 0.8 to 100% while in most studies the use rate was below 50%. Key barriers to HIVST use were coping with a positive test in the absence of counselling and support, physical discomfort, and cost of kits. Perceived enablers included perceptions of HIVST as promoting personal empowerment and autonomy; privacy and confidentiality; and convenience in location, time, and skill.ConclusionsHIVST was highly accepted but not well utilized among YP in SSA. YP showed diversified needs with mixed preferences for location, and modalities of service provision. Overall, the review identified heterogeneous evidence in terms of methods, population, outcome measures, and results. The review was registered in the International Prospective Registry of Systematic Reviews (PROSPERO: ID = CRD42021278919).

Profile Of Infectious Complications in Pediatric Oncology Patients: Experience from Tertiary Referral Hospital in Low and Middle-Income Country

Abstract Background Cancer patients are at higher risk of infections and more likely to have higher morbidity and mortality than the general population, While cancer itself is still the main cause of death in children around the world, in countries with limited health facilities, that might cause delay in seeking treatment, cancer death rate in children could reach 90%; most of them are caused by infectious complications such as typhilitis and mucositis, and febrile neutropenia might contribute to it. The aim of the study was to describe that infectious complications that occur in pediatric oncology patients does correlate with febrile neutropenia and prognosis. Methods We collected data using Hospital Information System from October 1, 2022, to October 31, 2023, in pediatric oncology patients aged 1 to 18 years admitted to Hasan Sadikin General Hospital. Data collected included patient characteristics, diagnosis, typhlitis and mucositis, and neutropenia. Mortality data were also collected after auditing by experts from Hasan Sadikin General Hospital. Results There were 1982 pediatric oncology patients admitted, 90 (4,5%) were consulted to infectious diseases because of neutropenia; most of these patients (34.4%) were diagnosed with acute myeloblastic leukemia, with acute lymphoblastic leukemia second (24,4%). Most of the patients were <5 years old (42,25%); 77/90 (85,5%) had ANC<500 and most were categorized as high-risk group 62/77 (80,5%). Mucositis and typhlitis occurred more commonly in this group with 17/67 (25,3%) and 2/67 (2,9 %) respectively compared to 3 cases of mucositis and no case of typhlitis in the low-risk group. Mortality rate was 10,4% (7/67) in the high-risk group, and all of them had mucositis and/or typhlitis. Conclusion Better quality of care including infection prevention and control is important, especially in high-risk group population with low ANC because infectious complications such as typhlitis and mucositis are much likely to occur and could affect prognosis.

Vision loss and diabetic retinopathy prevalence and risk among a cohort of Indigenous and non-Indigenous Australians with type 2 diabetes receiving renal haemodialysis treatment: The retinopathy in people currently on renal dialysis (RiPCORD) study

AimsDiabetic nephropathy, vision loss and diabetic retinopathy (DR) are frequent comorbidities among individuals with type 2 diabetes (T2D). The Retinopathy in People Currently On Renal Dialysis (RiPCORD) study sought to examine the epidemiology and risk of vision impairment (VI) and DR among a cohort of Indigenous and non-Indigenous Australians with T2D currently receiving haemodialysis for end-stage renal failure (ESRF). MethodsA total of 106 Indigenous and 109 non-Indigenous Australians were recruited in RiPCORD across five haemodialysis centres in urban and remote settings. Clinical assessments, questionnaires and medical record data determined the rates of ocular complications and risk factor profiles. ResultsPrevalence rates include unilateral VI, 23.5 %; bilateral VI, 11.7 %; unilateral blindness, 14.2 %; and bilateral blindness, 3.7 %, with no significant differences between sub-cohorts (p=0.30). DR prevalence rates were 78.0 % among non-Indigenous Australians and 93.1 % among Indigenous Australians (p=<0.001). Non-Indigenous ethnicity (OR: 0.28) and pre-dialysis diastolic blood pressure (OR: 0.84 per 10-mmHg) were protective, while peripheral vascular disease (OR: 2.79) increased DR risk. ConclusionsOcular complications among individuals with T2D and ESRF are disproportionately high, especially for Indigenous Australians, and beyond what can be accounted for by risk factor variation. Findings suggest a need to improve screening and preventative efforts within this high-risk population group.

Global Seroprevalence of Tick-Borne Encephalitis Antibodies in Humans, 1956-2022: A Literature Review and Meta-Analysis.

Despite the availability of tick-borne encephalitis (TBE) vaccines, the incidence of TBE is increasing. To understand the historical patterns of infection, we conducted a global meta-analysis of studies before December 2023 reporting human antibody prevalence against TBEV (TBE virus) among general or high-risk population groups stratified by country, collection year, serological method, and vaccination status. Pooled data were compared within groups over time by random-effects modeling. In total, 2403 articles were retrieved; 130 articles published since 1959 were included. Data were extracted from 96 general populations (117,620 participants) and 71 high-risk populations (53,986 participants) across 33 countries. Germany had the most population groups (21), and Poland had the most participants (44,688). Seven serological methods were used; conventional IgG/IgM ELISAs were the most common (44%). Four studies (1.7%) used NS1-ELISA serology. Between 1956-1991 and 1992-2022, anti-TBEV seroprevalence remained at ~2.75% across all population groups from "high-risk" areas (p = 0.458) but decreased within general populations (1.7% to 1%; p = 0.001) and high-risk populations (5.1% to 1.3%; p < 0.001), possibly due to differences in the study methodologies between periods. This global summary explores how serological methods can be used to assess TBE vaccination coverage and potential exposure to TBEV or measure TBE burden and highlights the need for standardized methodology when conducting TBE seroprevalence studies to compare across populations.

Determinants of parental demand of human papillomavirus vaccination for adolescent daughters in China: Contingent valuation survey.

Several types of human papillomavirus (HPV) vaccines have been approved for use in adolescent girls in China. These vaccines are regulated as non-National Immunisation Program vaccines and are optional and generally fully self-paid by vaccinees. To assess parents' demand for HPV vaccination by eliciting their willingness-to-pay for their adolescent daughters to be vaccinated against HPV and to examine the determinants of demand for HPV vaccination in China. A contingent valuation survey was conducted across three cities in Shandong Province in eastern China. We selected 11 junior middle schools with different socioeconomic features and randomly selected 6 classes in each school, and questionnaires were distributed to all girls aged 12-16 in the 66 classes for their parents to complete. A payment card approach was used to elicit parental willingness-to-pay for HPV vaccination for their daughters. We also collected a wide array of socioeconomic and psychological variables and interval regressions were applied to examine the determinants of parental willingness-to-pay. A total of 1074 eligible parents who completed valid questions were included in analyses. Over 85% of parents believed HPV vaccines were, in general, necessary and beneficiary. However, only around 10% believed that their daughters would be infected by HPV. About 8% of parents would not accept HPV vaccine even if the vaccine were free mainly due to concerns about the potential side effects and vaccine safety and quality issues, and 27.37% would only accept the vaccine if it were free. The median willingness-to-pay was 300 CNY (42 USD). Several factors were positively correlated with higher willingness-to-pay: income, urban residence (relative to rural residence), mothers (relative to fathers), parents' beliefs about vaccine benefits, whether they should make decisions for their daughters, and whether their daughters would be susceptible to HPV. Though education-level was not significantly correlated with willingness-to-pay in the main regressions, a subgroup analysis revealed interesting dynamics in the relation between education and willingness-to-pay across different income-levels. There is a large gap between parents' willingness-to-pay and the market price of HPV vaccine for girls in China. Parents generally believed the HPV vaccines were beneficial and necessary but when asked for their daughters, most parents did not believe their daughters would be infected by HPV despite the high prevalence in China. Future focus should be on ensuring the provision of accurate health information about HPV prevalence, vaccine quality, and safety to promote vaccine uptake, and promotional efforts tailored to different income groups might yield better effects. Government involvement in negotiating more widely acceptable and affordable prices or subsidising may be necessary for protecting high-risk population groups.

Reduced seasonal coronavirus incidence in high-risk population groups during the COVID-19 pandemic.

Epidemiological data on seasonal coronaviruses (sCoVs) may provide insight on transmission patterns and demographic factors that favor coronaviruses (CoVs) with greater disease severity. This study describes the incidence of CoVs in several high-risk groups in Ottawa, Canada, from October 2020 to March 2022. Serological assays quantified IgG and IgM antibodies to SARS-CoV-2, HCoV-OC43, HCoV-NL63, HCoV-HKU1, and HCoV-229E. Incident infections were compared between four population groups: individuals exposed to children, transit users, immunocompromised, and controls. Associations between antibody prevalence indicative of natural infection and demographic variables were assessed using regression analyses. Transit users and those exposed to children were at no greater risk of infection compared to the control group. Fewer infections were detected in the immunocompromised group (p = .03). SARS-CoV-2 seroprevalence was greater in individuals with low income and within ethnic minorities. Our findings suggest that nonpharmaceutical interventions intended to reduce SAR-CoV-2 transmission protected populations at high risk of exposure. The re-emergence of sCoVs and other common respiratory viruses alongside SARS-CoV-2 may alter infection patterns and increase the risk in vulnerable populations.

A Systematic Review of Cost-Effectiveness Studies on Gastric Cancer Screening.

Gastric cancer (GC) poses notable economic and health burdens in settings where the incidence of disease is prevalent. Some countries have established early screening and treatment programs to address these challenges. The objectives of this systematic review were to summarize the cost-effectiveness of gastric cancer screening presented in the literature and to identify the critical factors that influence the cost-effectiveness of screening. This systematic review followed the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) guidelines. Economic evaluation studies of gastric cancer screening were reviewed from SCOPUS and PubMed. The Consolidated Health Economic Evaluation Reporting Standards 2022 (CHEERS 2022) was used to assess the quality of reporting presented in the selected articles. Only primary economic evaluation studies addressing the cost-effectiveness, cost-utility, and cost-benefit of gastric cancer screening were selected. Two reviewers scrutinized the selected articles (title, abstract, and full text) to determine suitability for the systematic review based on inclusion and exclusion criteria. Authors' consensus was relied on where disagreements arose. The main outcome measures of concern in the systematic review were cost, effectiveness (as measured by either quality-adjusted life years (QALY) or life-years saved (LYS)), and incremental cost-effectiveness ratio (ICER) of screening versus either no screening or an alternative screening method. Thirty-one studies were selected for the final review. These studies investigated the cost-effectiveness of GC screening based on either primary, secondary, or a combination of primary and secondary interventions. The main primary intervention was Helicobacter pylori (Hp) screening with eradication, while the main secondary intervention was endoscopic screening. Cost-effectiveness was evaluated against no screening or screening using an alternative method in both observational and model-based studies. Screening was mainly cost-effective in Asian countries or their diasporas where the prevalence of GC was high. GC screening was generally not cost-effective among Western countries. GC screening can be cost-effective, but cost-effectiveness is dependent on context-specific factors, including geographical location, the prevalence of GC in the local population, and the screening tool adopted. However, there is benefit in targeting high-risk population groups in Asian countries and their diaspora for GC screening.

A Qualitative Study on Unmet Mental Health Needs of Indian Human Immunodeficiency Virus-positive Men Who Have Sex with Men

Background: The prevalence of human immunodeficiency virus (HIV) infection in the population of men who have sex with men (MSM) in India is higher than that of the general population, making them one of the high-risk population groups. This subgroup is also at a higher risk for mental disorders, substance use, and stigma due to their MSM status. There is a paucity of data about this in the Indian HIV-positive MSM subgroup. Aim: The study aimed to explore the understanding of “mental health” among MSM living with HIV and bring forth their unmet mental health needs. Methods: The study used a qualitative design with purposive sampling. Seven people living with HIV from a randomly selected antiretroviral therapy center in Mumbai, who identified as MSM, participated in the study. Data were collected through focus group discussion, audio recorded with consent, and then a thematic analysis of the transcript was done. Results: The responses were summarized into four broad categories – mental health problems, psychosocial and economic problems, philosophical conflicts, and coping strategies. The categories further generated multiple themes. Themes such as worries about the illness, fear of impending death, low self-esteem, stigma around HIV and homosexuality, and perceived and experienced discrimination were recurrent. Mental illness was perceived as an additional burden to their already existing health problem. Conclusion: This study provided a deeper understanding of the unmet mental health needs and psychosocial challenges faced by the HIV-infected Indian MSM. It may help the policymakers of the country to modify the existing health and social benefit schemes.

Healthcare and Epidemiological Surveillance Costs of Hepatitis A Outbreaks in Spain in Regions with and without Universal Hepatitis A Vaccination of Children during 2010-2018.

The aim of this study was to evaluate and compare hepatitis A outbreak-associated healthcare and epidemiological surveillance costs in Spain in two types of autonomous regions during 2010-2018: (1) regions with a prevention strategy based on universal hepatitis A vaccination of children and vaccination of high-risk population groups (Catalonia) and (2) regions with a prevention strategy based on vaccinating high-risk population groups (Castile and Leon, Murcia, Navarra, Community of Madrid, Community of Valencia). Healthcare costs were determined based on the resources used to treat hepatitis A outbreak-associated cases and hospitalizations. Epidemiological surveillance costs were calculated from the resources used during surveillance activities. The ratios for total, healthcare and epidemiological surveillance costs (regions without universal hepatitis A vaccination of children vs. Catalonia) were used to compare the two hepatitis A prevention strategies. From 2010 to 2018, the total, healthcare and epidemiological surveillance costs per million population were 1.75 times (EUR 101,671 vs. EUR 58,032), 1.96 times (EUR 75,500 vs. EUR 38,516) and 1.34 times greater (EUR 26,171 vs. EUR 19,515) in regions without universal hepatitis A vaccination of children than in Catalonia, respectively. The ratios tended to increase over time during 2010-2018. In 2015-2018, total, healthcare and epidemiological surveillance costs per million population were 2.68 times (EUR 69,993 vs. EUR 26,158), 2.86 times (EUR 53,807 vs. EUR 18,825) and 2.21 times greater (EUR 16,186 vs. EUR 7333) in regions without universal hepatitis A vaccination of children than in Catalonia, respectively. These findings suggest that universal hepatitis A vaccination of children could reduce hepatitis A outbreak-associated costs.

IntroductionRisk perceptions and precautionary actions against COVID-19 have been reported to be generally insufficient globally, and differences by subpopulation group have been concerning, as a key driver to widening health...

THE PREVALENCE OF DYSLIPIDEMIA IN THE POPULATION OF THE REPUBLIC OF MOLDOVA (PRELIMINARY DATA)

Dyslipidemias are among the most important modifiable risk factors associated with cardiovascular pathology. Materials and methods. The preliminary results of the observational, cross-sectional study conducted from February 2020 to January 2023 are presented. The prevalence of dyslipidemia and the lipid profile in a sample of 728 participants from rural and urban environments were analyzed. Results: In a group of participants with a mean age of 47.14 ± 12.65 years, it was observed that elevated LDL- cholesterol and decreased HDL-cholesterol levels were the most frequent abnormal lipid parameters in men, and in women isolated elevation of LDL-cholesterol was often recorded. Conclusions: The study emphasizes the importance of early screening in apparently healthy populations. Early diagnosis may identify high-risk population groups, where early intervention may lead to avoidance of later complications related to dyslipidemia.

Trends in Health-Risk Behaviors and Psychological Distress among Australian First-Year University Students.

University students are recognized as a high-risk population group who experience greater rates of poor health outcomes and mental ill-health. Commencing university is recognized as a major life transition, where students experience new financial, academic, environmental, and social pressures that can cause changes in their normal behaviors. This study explored trends in health-risk behaviors and psychological distress in commencing university students over four survey years. First-year undergraduate students, aged 17-24, from an Australian university were included. A secondary analysis was performed on data collected via cross-sectional surveys on four occasions (2016, 2017, 2019, 2020). Crude logistic regression models were utilized to investigate the association between meeting guidelines and survey year. Odds ratios for the pairwise comparison between each year are reported. In this analysis, 1300 (2016), 484 (2017), 456 (2019), and 571 (2020) students were included. Analyses showed two clear trends: students' probability of being at high/very high risk of psychological distress (35-55%) and consuming breakfast daily (44-55%) consistently worsened over the four survey years. These findings suggest that the odds of psychological distress and daily breakfast consumption worsened over time, whilst the proportion of students engaging in some health-risk behaviors was high, highlighting the importance of early intervention during the transition to university.

The changing health effects of air pollution exposure for respiratory diseases: a multicity study during 2017–2022

BackgroundMultifaceted SARS-CoV-2 interventions have modified exposure to air pollution and dynamics of respiratory diseases. Identifying the most vulnerable individuals requires effort to build a complete picture of the dynamic health effects of air pollution exposure, accounting for disparities across population subgroups.MethodsWe use generalized additive model to assess the likely changes in the hospitalisation and mortality rate as a result of exposure to PM2.5 and O3 over the course of COVID-19 pandemic. We further disaggregate the population into detailed age categories and illustrate a shifting age profile of high-risk population groups. Additionally, we apply multivariable logistic regression to integrate demographic, socioeconomic and climatic characteristics with the pollution-related excess risk.ResultsOverall, a total of 1,051,893 hospital admissions and 34,954 mortality for respiratory disease are recorded. The findings demonstrate a transition in the association between air pollutants and hospitalisation rates over time. For every 10 µg/m3 increase of PM2.5, the rate of hospital admission increased by 0.2% (95% CI: 0.1–0.7%) and 1.4% (1.0–1.7%) in the pre-pandemic and dynamic zero-COVID stage, respectively. Conversely, O3-related hospitalization rate would be increased by 0.7% (0.5–0.9%) in the pre-pandemic stage but lowered to 1.7% (1.5–1.9%) in the dynamic zero-COVID stage. Further assessment indicates a shift of high-risk people from children and young adolescents to the old, primarily the elevated hospitalization rates among the old people in Lianyungang (RR: 1.53, 95%CI: 1.46, 1.60) and Nantong (RR: 1.65, 95%CI: 1.57, 1.72) relative to those for children and young adolescents. Over the course of our study period, people with underlying diseases would have 26.5% (22.8–30.3%) and 12.7% (10.8–14.6%) higher odds of having longer hospitalisation and over 6 times higher odds of deaths after hospitalisation.ConclusionsOur estimates provide the first comprehensive evidence on the dynamic pollution-health associations throughout the pandemic. The results suggest that age and underlying diseases collectively determines the disparities of pollution-related health effect across population subgroups, underscoring the urgency to identifying the most vulnerable individuals to air pollution.

Assessing New York City's COVID-19 Vaccine Rollout Strategy: A Case for Risk-Informed Distribution.

This study reviews the impact of eligibility policies in the early rollout of the COVID-19 vaccine on coverage and probable outcomes, with a focus on New York City. We conducted a retrospective ecological study assessing age 65+, area-level income, vaccination coverage, and COVID-19 mortality rates, using linked Census Bureau data and New York City Health administrative data aggregated at the level of modified zip code tabulation areas (MODZCTA). The population for this study was all individuals in 177 MODZCTA in New York City. Population data were obtained from Census Bureau and New York City Health administrative data. The total mortality rate was examined through an ordinary least squares (OLS) regression model, using area-level wealth, the proportion of the population aged 65 and above, and the vaccination rate among this age group as predictors.Low-income areas with high proportions of older people demonstrated lower coverage rates (mean vaccination rate 52.8%; maximum coverage 67.9%) than wealthier areas (mean vaccination rate 74.6%; maximum coverage 99% in the wealthiest quintile) in the first 3months of vaccine rollout and higher mortality over the year. Despite vaccine shortages, many younger people accessed vaccines ahead of schedule, particularly in high-income areas (mean coverage rate 60% among those 45-64years in the wealthiest quintile). A vaccine program that prioritized those at greatest risk of COVID-19-associated morbidity and mortality would have prevented more deaths than the strategy that was implemented. When rolling out a new vaccine, policymakers must account for local contexts and conditions of high-risk population groups. If New York had focused limited vaccine supply on low-income areas with high proportions of residents 65 or older, overall mortality might have been lower.

Healthy@Home, An Integrated Health and Social Care Program for a Marginalized Population Group in Toronto, Canada

Introduction: Integrated health and social care (IHSC) can support improved health and social care outcomes for highly vulnerable and marginalized population groups. Toronto has one of the most diverse populations in the world. Immigrants account for 46% of the city's population. Russian-speaking Jewish older adults are a population group who are at significant risk of isolation and poor access to health and social services. In response an adult day program, Healthy@Home (H@H) was established through multi-organizational partnership among community-based health and social care outcomes led by social services agencies has spread to 20 sites across Canada.&#x0D; Methodology: a qualitative study of H@H was undertaken to explore the factors that support successful integrated services delivery for this high-risk population group. Key informant interviews and focus groups were completed involving eight health and social care agencies to explore the factors that support successful IHSC. &#x0D; Results: The qualitative study identified eleven critical factors that support IHSC among many health and social care agencies. They include strong communications, shared vision and goals, team-based care, dedicated resources, inter-organizational culture, and pre-existing relationships were overwhelmingly regarded as being key to the success of H@H partnerships. Leadership and accountability agreements were also regarded as being important factors. The H@H case also identified pre-existing relationships, role clarity and champions that contributed towards its integration success. The H@H case offers up some unique insights into how context can have an important role in influencing IHSC and that may be unique to services provision in Toronto. Ten contextual factors were identified as having exerted an influence on services partnership. They include aging population, immigration population, transportation, differences in the healthcare and social care sectors, accountability agreements with governing authorities and funders, public funding, governance authorities, sense of community among the providers, public policies and being part of the not-for-profit sector.&#x0D; Lessons Learned: The H@H study has shown that IHSC can occur voluntarily and at the grass-roots level. It also provides insights into how IHSC can be initiated and driven by social services agencies who are united by a shared vision and goal, and a strong sense of community. Despite limited funding and external resources, these organizational partners have been able to engage in IHSC for more than a decade in order to respond to a significant unmet need for a population group that was being ignored and marginalized due to their socio-economic status, their immigration status, and language barriers by existing health and welfare systems. Their isolation from mainstream society put them at significant risk of falling through the Canadian welfare system cracks. These community-based agencies, with close ties to their neighbourhoods were able to engage, respond, coordinate, and integrate flexibly. Contextual factors including a supportive policy environment that was aimed at supporting ageing in place, seniors care, poverty reduction and immigrants and a vibrant community of culturally competent providers has made H@H a success.

The association between non-viral sexually transmitted infections and pregnancy outcome in Latin America and the Caribbean: A systematic review

IntroductionNon-viral sexually transmitted infections are known to be associated with adverse pregnancy outcomes. For these pathogens, standard antenatal screening is not broadly performed in Latin America and the Caribbean. The aim of this study was to comprehensively review the association of non-viral sexually transmitted infections and neonatal outcomes among pregnant women in the region. MethodsFour databases (PubMed, Embase, SciELO and LILACS) were examined to identify eligible studies published up to September 2022. English or Spanish cross-sectional, case-control and cohort studies assessing the association of non-viral sexually transmitted infections and adverse pregnancy outcomes were evaluated. Articles were firstly screened by means of title and abstract. Potential articles were fully read and assessed for inclusion according to the eligibility criteria. Snowballing search was performed by screening of bibliographies of the chosen potentially relevant papers. Risk of bias within studies was assessed using the Joanna Briggs Institute reviewer's manual. ResultsA selection of 10 out of 9772 search records from five Latin America and the Caribbean countries were included. Six studies associated Treponema pallidum infection with preterm birth (1/6), history of previous spontaneous abortion (2/6), fetal and infant death (1/6), low birth weight (1/6) and funisitis of the umbilical cord (1/6). Three studies associated Chlamydia trachomatis infection with preterm birth (2/3), ectopic pregnancy (1/3) and respiratory symptoms on the newborn (1/3). One study associated Mycoplasma genitalium infection with preterm birth. ConclusionThis review provides evidence on the association of non-viral sexually transmitted infections with adverse pregnancy outcomes. Further investigation is needed to establish more associations between non-viral sexually transmitted infections and pregnancy outcome, especially for Mycoplasma genitalium, Trichomonas vaginalis and Neisseria gonorrhoeae. Overall, this review calls for more research for public health interventions to promote screening of non-viral sexually transmitted infections during pregnancy, among high-risk population groups of pregnant women living in the region.

Sexually transmitted infections and associated risk factors among the transgender population of Pakistan

BackgroundTransgender (TG) people are key drivers for sexually transmitted infections (STIs) all over the world. There is substantial evidence that STIs are associated with an increased likelihood of risky sexual behavior however little is known about the prevalence of STIs (HIV, HBV, HCV, and Syphilis) among HIV infected transgender population in Pakistan.MethodsThe current study investigated the seroprevalence of four STIs and associated socio-demographic risk factors among TGs of Punjab, Pakistan from July 2019 to June 2021. The samples were tested serologically and final confirmation was done through PCR for HIV, HBV, and HCV.ResultsA total of 1,562 transgenders cross-sectional descriptive records of the Punjab AIDS Control Program (PACP) were reviewed during the period from July 2019 to June 2021. The serological results evidenced that 533 (34.1%) had one pathogen, 309 (19.8%) had two or more (multiple) infections. The most predominant mono-infection among the transgender population was Syphilis 324 (20.7%) followed by HCV 114 (7.3%), HIV 69 (4.4%), and HBV 26 (1.7%). The highest proportions of Infections were found in TG residing in urban areas (68.6%) as compared to rural areas (31.4%). The seropositivity of all STIs was predominantly increased in Sex worker TGs i-e 55%, 46.5%, 38.5%, and 41.8% in HIV, HBV, HCV, and Syphilis respectively. Among 280 HIV-infected Transgender, 177 (63.2%) had Syphilis co-infections. While 87 (31%) and 47 (16.8%) HIV-infected individuals had HC and HBV co-infection respectively.ConclusionTransgender is neglected population group in society. All STIs were predominantly common among sex worker transgenders, Illiterate educational groups, and TGs residing in urban areas. There is a need to spread awareness about STIs, preventive strategies, and facilitation to health care programs in this high-risk population group.

Development and validation of COEWS (COVID-19 Early Warning Score) for hospitalized COVID-19 with laboratory features: A multicontinental retrospective study.

The emergence of new SARS-CoV-2 variants with significant immune-evasiveness, the relaxation of measures for reducing the number of infections, the waning of immune protection (particularly in high-risk population groups), and the low uptake of new vaccine boosters, forecast new waves of hospitalizations and admission to intensive care units. There is an urgent need for easily implementable and clinically effective Early Warning Scores (EWSs) that can predict the risk of complications within the next 24-48 hr. Although EWSs have been used in the evaluation of COVID-19 patients, there are several clinical limitations to their use. Moreover, no models have been tested on geographically distinct populations or population groups with varying levels of immune protection. We developed and validated COVID-19 Early Warning Score (COEWS), an EWS that is automatically calculated solely from laboratory parameters that are widely available and affordable. We benchmarked COEWS against the widely used NEWS2. We also evaluated the predictive performance of vaccinated and unvaccinated patients. The variables of the COEWS predictive model were selected based on their predictive coefficients and on the wide availability of these laboratory variables. The final model included complete blood count, blood glucose, and oxygen saturation features. To make COEWS more actionable in real clinical situations, we transformed the predictive coefficients of the COEWS model into individual scores for each selected feature. The global score serves as an easy-to-calculate measure indicating the risk of a patient developing the combined outcome of mechanical ventilation or death within the next 48 hr.The discrimination in the external validation cohort was 0.743 (95% confidence interval [CI]: 0.703-0.784) for the COEWS score performed with coefficients and 0.700 (95% CI: 0.654-0.745) for the COEWS performed with scores. The area under the receiver operating characteristic curve (AUROC) was similar in vaccinated and unvaccinated patients. Additionally, we observed that the AUROC of the NEWS2 was 0.677 (95% CI: 0.601-0.752) in vaccinated patients and 0.648 (95% CI: 0.608-0.689) in unvaccinated patients. The COEWS score predicts death or MV within the next 48 hr based on routine and widely available laboratory measurements. The extensive external validation, its high performance, its ease of use, and its positive benchmark in comparison with the widely used NEWS2 position COEWS as a new reference tool for assisting clinical decisions and improving patient care in the upcoming pandemic waves.

Evaluating Alterations of the Oral Microbiome and Its Link to Oral Cancer among Betel Quid Chewers: Prospecting Reversal through Probiotic Intervention.

Areca nut and slaked lime, with or without tobacco wrapped in Piper betle leaf, prepared as betel quid, is extensively consumed as a masticatory product in many countries across the world. Betel Quid can promote the malignant transformation of oral lesions as well as trigger benign cellular and molecular changes. In the oral cavity, it causes changes at the compositional level in oral microbiota called dysbiosis. This dysbiosis may play an important role in Oral Cancer in betel quid chewers. The abnormal presence and increase of bacteria Fusobacterium nucleatum, Capnocytophaga gingivalis, Prevotella melaninogenica, Peptostreptococcus sp., Porphyromonas gingivalis, and Streptococcus mitis in saliva and/or other oral sites of the cancer patients has attracted frequent attention for its association with oral cancer development. In the present review, the authors have analysed the literature reports to revisit the oncogenic potential of betel quid and oral microbiome alterations, evaluating the potential of oral microbiota both as a driver and biomarker of oral cancer. The authors have also shared a perspective that the restoration of local microbiota can become a potentially therapeutic or prophylactic strategy for the delay or reversal of lip and oral cavity cancers, especially in high-risk population groups.

Long term outcomes and causal modelling of compulsory inpatient and outpatient mental health care using Norwegian registry data: Protocol for a controversies in psychiatry research project.

Compulsory mental health care includes compulsory hospitalisation and outpatient commitment with medication treatment without consent. Uncertain evidence of the effects of compulsory care contributes to large geographical variations and a controversy on its use. Some argue that compulsion can rarely be justified and should be reduced to an absolute minimum, while others claim compulsion can more frequently be justified. The limited evidence base has contributed to variations in care that raise issues about the quality/appropriateness of care as well as ethical concerns. To address the question whether compulsory mental health care results in superior, worse or equivalent outcomes for patients, this project will utilise registry-based longitudinal data to examine the effect of compulsory inpatient and outpatient care on multiple outcomes, including suicide and overall mortality; emergency care/injuries; crime and victimisation; and participation in the labour force and welfare dependency. By using the natural variation in health providers' preference for compulsory care as a source of quasi-randomisation we will estimate causal effects of compulsory care on short- and long-term trajectories. This project will provide valuable insights for service providers and policy makers in facilitating high quality clinical care pathways for a high risk population group.
