Efficacy and safety of higher dose rifampicin in adults with presumed drug-susceptible tuberculosis: an updated systematic review and meta-analysis

Tuberculosis (TB) remains a significant cause of mortality globally, yet first-line treatment has hardly changed for fifty years. The dose of rifampicin, the most important drug in this regimen, has been historically based on pragmatic cost- and risk-benefit considerations. Evidence suggests the current recommended dose (8-12mg/kg) may not maximise the potential benefits of this drug. We sought to evaluate the efficacy and safety of higher doses of rifampicin in adults with presumed drug-susceptible TB. In this systematic review we searched MEDLINE, EMBASE, CENTRAL and Global Health databases for randomised controlled trials up to 31 July 2024 of adults with presumed drug-susceptible TB receiving first-line treatment with an intervention of rifampicin doses higher than currently recommended. Meta-analyses were performed using random effects models where background regimens were the same. Risk ratio was used as the measure for treatment effect. Outcomes of interest related to efficacy and safety. Of the 5441 total records identified by our searches, nineteen studies (6332 patients, 31.0% female) were eligible for the systematic review and twelve (3763 patients, 31.0% female) for meta-analysis. Rifampicin doses varied from 8 to 35mg/kg and implementation of the intervention varied between trials. There was no evidence for increased efficacy with higher doses of rifampicin, however the majority of trials investigated minimally increased doses (up to 20mg/kg). At higher doses (>20mg/kg), there may be evidence of increased risk of drug-induced liver injury, albeit with no consistent dose-response relationship. Evidence on the efficacy of higher doses of rifampicin in the first-line regimen for TB remains incomplete. While higher doses appear generally safe, the risk of drug-induced liver injury may be increased above doses of 20mg/kg. Larger clinical trials reporting definitive outcomes are needed to determine whether dosing up to 40mg/kg could safely improve treatment outcomes or reduce duration of first-line therapy.

Perinatal depression and adverse child growth outcomes in low-income and middle-income countries (LMICs): A systematic review and meta-analysis.

Perinatal depression (PND), which encompasses the antepartum and postpartum depression (APD and PPD), is a neglected crisis in low-income and middle-income countries (LMICs). We aimed to systematically search and meta-analyze existing evidence to determine whether a mother's PND affects adverse growth outcomes in children in LMICs (PROSPERO protocol: CRD42021246803). We conducted searches, including nine databases (PubMed, EMBASE, Web of Science, CINAHL Plus, Global Health Database, Google Scholar, WHO Regional Databases, PsycINFO, and LILACS) from January 2000 to September 2023. We restricted studies that assessed PND using validated screening tools or clinical interviews during pregnancy or within 12 months postpartum. We included studies that reported four types of adverse child growth outcomes (stunting, wasting, underweight, and overweight/obesity) in children younger than 5 years. We assessed the quality using the Newcastle Ottawa Scale and pooled risk ratios (RRs) and odds ratios (ORs) between PND and each adverse growth outcome using random-effects models. In total, 27 studies met the inclusion criteria for systematic review, with 24 eligible for meta-analysis, spanning data from 15 countries and 26,261 mother-baby pairs. Based on the studies that reported ORs, children below the age of 3 years with mothers experiencing PND had higher odds for stunting (OR 1.63, 95% CI 1.32, 2.02, I2 = 56.0%) and underweight (OR 2.65, 95% CI 1.90, 3.68, I2 = 34.5%) compared to children of mothers without PND. The pooled RRs for stunting and underweight did not show significant differences between mothers with and without PND. Studies on wasting (n = 5) and overweight/obesity (n = 2) were limited, demonstrating inconsistent results across studies. The association between PND and adverse growth outcomes varied according to the measure of association, region, country, PND type, outcome timepoint, and study design. There were limited studies in diverse LMICs, particularly on wasting, or overweight/obesity as an outcome.

Educational inequalities in cervical cancer mortality: A systematic review and meta-analysis

Abstract Background Educational inequalities in mortality continue to persist. We aimed to systematically analyse the association between level of education and cervical cancer mortality. Methods We conducted a systematic review and meta-analysis. We systematically searched Pub-Med, Web of Science, Scopus, EMBASE and Global Health (CAB), EconLit and Sociology Source Ultimate databases. A protocol has been registered with PROSPERO (CRD42023411757). We included studies that measured the association between level of education and cervical cancer mortality using individual level data. Included articles were assessed for study quality and risk of bias using the Joanna Briggs Institute critical appraisal checklists. A random-effects meta-analysis was conducted to evaluate the overall and stratified effects of education on mortality. Findings Our literature search resulted in over 47,000 articles. 30 studies mentioned cervical cancer as a cause of death, and of these, 11 were eligible for the meta-analysis. Results showed an overall risk ratio of 2.41 (95% CI 1.81-3.20) for low education (ISCED 0-2) and 1.62 (95% CI 1.18-2.24) for medium education (ISCED 3-4). Those aged 25-64 with low education had more than twice the risk of cervical cancer (RR = 5.73; 95% CI 5.04-6.51) compared to those aged 25 and above (RR = 2.11; 95% CI 1.82-2.45). Besides, the impact of an additional level of education on reducing risk of cervical cancer mortality was higher in Northern Europe, compared to the South. Interpretation Lower educational attainment is associated with an increase in the risk of cervical cancer mortality, with an additional level of education greatly reducing this risk in Northern Europe. Younger cohorts with low education have a higher risk of cervical cancer mortality. This study provides important information for evidence-based policy seeking to reduce health inequities and inequalities in both the health and education sector. Key messages • Lower educational attainment is linked to a higher risk of cervical cancer mortality. • Younger cohorts (aged 25-64) with low education are at a particularly heightened risk compared to those aged 25 and above.

Effects of Blood Lead Levels

Lead exposures among school-age children are a major public health issue. Although the harmful effects of lead exposure during the first years of life are well known, there is not as much understanding of the effects of low levels of lead exposure during later childhood. To review the effects of blood lead levels (BLLs) <10 µg/dL in school-age children and adolescents. We searched Medline, Embase, Global health, CINAHL, Scopus, and Environmental Science Collection databases between January 1, 2000, and May 11, 2023. We included peer-reviewed English-language articles that presented data on the effects of BLLs <10 µg/dL in individuals ages 5 through 18 years. Data on country, population, analytic design, sample size, age, BLLs, outcomes, covariates, and results were extracted. Overall, 115 of 3180 screened articles met the inclusion criteria. The reported mean or median BLL was <5 µg/dL in 98 articles (85%). Of the included articles, 89 (77%) presented some evidence of an association between BLLs <10 µg/dL during school age and detrimental outcomes in a wide range of categories. The strongest evidence of an association was for the outcomes of intelligence quotient and attention-deficit/hyperactivity disorder diagnoses or behaviors. Few articles controlled for BLLs at age <5 years, limiting conclusions about the relation between later BLLs and outcomes. BLLs <10 µg/dL in school-age children and adolescents may be associated with negative outcomes. This review highlights areas that could benefit from additional investigation.

Association between pregnancy intention and completion of newborn and infant continuum of care in Sub-Saharan Africa: systematic review and meta-analysis

BackgroundThe newborn and infant continuum of care such as essential newborn care, early initiation and exclusive breastfeeding, and immunisation are highly recommended for improving the quality of life and survival of infants. However, newborn and infant mortality remains high across Sub-Saharan African countries. While unintended pregnancies are associated with adverse newborn and infant health outcomes, there is inconclusive evidence on whether pregnancy intention influences newborn and infant continuum of care completion. Therefore, this review aimed to pool findings reported in the literature on the association between pregnancy intention and newborn and infant health care across the continuum of care in Sub-Saharan Africa.MethodsWe searched MEDLINE Complete, EMBASE, CINAHL Complete, and Global Health databases for studies potentially eligible for this systematic review and meta-analysis. Two researchers independently screened the identified articles by abstract and title, and then full-text using Covidence. We used the Newcastle–Ottawa Scale to assess the quality of the included studies. The Cochran’s Q test and I2 were executed to detect and quantify the presence of statistical heterogeneity in the studies. Meta-analysis was done for each outcome when more than one original study reported relevant data, using Stata statistical software version 18.ResultsEleven studies were included from a total of 235 articles identified by the search. The odds of completing essential newborn care (pooled odds ratio: 3.04, 95% CI: 1.56, 5.90), early initiation of breastfeeding (pooled odds ratio: 1.30, 95% CI: 1.13, 1.52), exclusive breastfeeding (pooled odds ratio: 2.21, 95% CI: 1.68, 2.89), and being fully immunised (pooled odds ratio: 2.73, 95% CI: 1.16, 6.40) were higher among infants born to women with intended pregnancies as compared to women with unintended pregnancies.ConclusionIntended pregnancy was positively associated with essential newborn care completion, early initiation and exclusive breastfeeding, and full immunisation of infants in SSA countries. Thus, policy-makers and stakeholders should strengthen the provision of quality family planning services to prevent unintended pregnancy. Furthermore, follow-up of women with unintended pregnancies is needed to increase women’s opportunity to access essential newborn health care services that further reduce the risk of newborn and infant morbidity and mortality.Systematic review registrationPROSPERO registration number CRD42023409148.

Effects of multi-component parenting and parental mental health interventions on early childhood development and parent outcomes: a systematic review and meta-analysis

Interventions supporting parents of young children often target parenting or parental mental health separately. Multi-component parenting and parental mental health interventions have the potential to improve parenting practices, mental health, and early childhood development. We aimed to examine their impact on child and parent outcomes. In this systematic review and meta-analysis, we searched MEDLINE, Embase, Web of Science Core Collection, APA PsycINFO, CINAHL Complete, the Cochrane Central Register of Controlled Trials, and the Global Health Database from inception to Jan 23, 2024. Eligible studies were randomised controlled trials of interventions explicitly targeting parenting behaviours and parental mental health antenatally or in children's first 3 years of life. Screening, extraction, and quality assessment were done independently by two authors. Primary outcomes were cognitive and social-emotional functioning in children and depressive symptoms in parents, meta-analysed as standardised mean differences (SMDs), relative to control. This study is registered with PROSPERO, CRD42022302848. We found 5843 records. After screening 2636 (45·1%) titles and abstracts, we manually identified and screened three additional articles and excluded 2177 records. After screening 462 full-length articles, 25 articles, representing a sample size of 8520 children and caregivers, were included. At baseline, mean caregiver age was 27·7 years (SD 5·9) and mean child age (excluding those enrolled during pregnancy) was 14·4 months (8·0). Interventions lasted a mean of 14 months (SD 11) and used a mean of 3·7 behaviour change techniques (2·0). Most interventions dedicated more time to parenting behaviours than to parental mental health. We found significant intervention effects on children's cognitive (SMD 0·19 [95% CI 0·04 to 0·34]; I2=69%) and social-emotional (0·26 [0·17 to 0·34]; I2=47%) outcomes but not on depressive symptoms in female caregivers (-0·18 [-0·36 to 0·002]; I2=86%) relative to control conditions. Risk of bias across studies was moderate, and we found heterogeneity across results. Multi-component parenting and mental health interventions had a positive effect on child cognitive and social-emotional outcomes, but not on depressive symptoms in parents, suggesting that other factors might contribute to positive ECD outcomes. Interventions might lack adequate focus on mental health to make a discernible impact, highlighting a need for future studies to differentiate and assess contributions of parenting and mental health components to understand independent and collective effects on family outcomes.

Burden of Respiratory Syncytial Virus (RSV) Infection Among Adults in Nursing and Care Homes: A Systematic Review.

Older adults in nursing and care homes (NCHs) are vulnerable to severe respiratory syncytial virus (RSV) infection, hospitalization, and death. This study aimed to gather data on RSV disease among older adults in NCHs and identify reported risk factors for RSV hospitalization and case fatality. The study protocol was registered in PROSPERO (CRD42022371908). We searched MEDLINE, EMBASE, and Global Health databases to identify articles published between 2000 and 2023. Observational and experimental studies conducted among older adults in NCHs requiring assistive care and reporting RSV illness were included and relevant data were extracted. Of 18,690 studies screened, 32 were selected for full-text review, and 20 were included. Overall, the number of NCH residents ranged from 42 to 1459 with a mean age between 67.6 and 85 years. Attack rates ranged from 6.7% to 47.6% and annual incidence ranged from 0.5% to 14%. Case fatality rates ranged from 7.7% to 23.1%. We found similar annual incidence rates of RSV-positive acute respiratory infection (ARI) of 4582 (95% CI: 3259-6264) and 4785 (95% CI: 2258-10,141) per 100,000 reported in two studies. Annual incidence rate of RSV-positive lower respiratory tract infection was 3040 (95% CI: 1986-4454) cases per 100,000 adults. Annual RSV-ARI hospital admission rates were between 600 (95% CI: 190-10,000) and 1104 (95% CI: 350-1930) per 100,000 person-years. Among all RSV disease cases, commonly reported chronic medical conditions included chronic obstructive pulmonary disease (COPD), heart failure, ischemic heart disease, coronary artery disease, hypertension, diabetes, kidney dysfunction, cerebrovascular accident, malignancies, dementia, and those with a Charlson comorbidity score > 6.5. Data on RSV infection among NCH residents are limited and largely heterogeneous but document a high risk of illness, frequent hospitalization, and high mortality. Preventive interventions, such as vaccination, should be considered for this high-risk population. Nationally representative epidemiologic studies and NCH-based viral pathogen surveillance could more precisely assess the burden on NCH residents.

Machine Learning-Based Cardiovascular Disease Prediction System to reduce the incidence of occurrence

Health is a paramount factor when considering any nation's sustainable growth and development. The concentration of the larger population of Nigerians is in the rural areas where public health infrastructures are either inadequate or not available. This has affected the larger labor force, leaving society vulnerable to high health. In recent times, one of the major health challenges facing rural and urban dwellers is heart disease occasioned by the non-existence of proper medical diagnosis. This study develops a machine learning model to predict the onset of heart disease to minimize onset cases of occurrence. The health prediction system is integrated with a prediction module to help in providing public healthcare services to rural dwellers. The developed system was comparatively achieved using hybrid machine learning techniques, which include a support vector machine and random forest in the design of the predictive module. The system integrates rural dwellers' health records with the global health database to form part of the Big Data for global access and considerations. The performance evaluation was achieved with the help of Random Forest. The system developed shows an average accuracy of 98% using machine learning algorithms. It also provides a convenient means for rural dwellers to access public health and enables them to receive health predictions to guide against fatal heart disease.

A scoping review of stroke registers in Sub-Saharan Africa.

Stroke registers are recommended as a key priority by the Lancet Neurology World Stroke Organization Commission for Stroke, 2023, and the African Stroke Leaders' Summit, 2022. This scoping review aims to map where stroke registers have been implemented in Sub-Saharan Africa (SSA). The article then compares and critiques the methods and definitions used and summarizes key results from the registers. The scoping review searched EMBASE, MEDLINE, and CABI Global Health databases and included all studies with a prospective longitudinal design in SSA, where adult acute stroke was the primary condition studied. Articles were screened against inclusion and exclusion criteria independently by two authors. We identified 42 unique stroke registers from 48 individual studies. The registers were located in 19 countries, with 19 from East Africa, 15 West Africa, 6 Central Africa, and 2 from Southern Africa. Cumulatively, the registers recruited 12,345 participants with stroke, the median number of participants was 183 (interquartile range (IQR): 121-312), and the range was 50-1018. Only one study was a population-based register, and 41 were hospital-based registers. Of the hospital-based registers, 29 were single site, 10 were conducted at two sites, and 2 at three sites. Twenty-three (54.7%) of the registers were located in the capital city of their respective country, and only one of the hospital-based registers was in a self-described rural area. Length of recruitment ranged from 4 months to 6 years; the median length of recruitment was 12 months. Methodology and definitions were heterogenous between the registers. Only seven (19.4%) registers referenced the WHO STEPwise approach to implementing stroke registers. Twenty-seven (64.3%) registers used the WHO definition of stroke. The mean neuroimaging rate was 84%, and ranged from 0% to 100%. Stroke severity was measured using the National Institute of Health Stroke Scale (NIHSS) in 22 (52.4%) registers, four registers used the Glasgow Coma Scale (GCS), two registers used the miniNIHSS, one used the Scandinavian Stroke Scale, one modified Rankin Scale (mRS), and 11 registers did not report a stroke severity measure. Seventeen (40.5%) registers used the mRS to measure function, six registers used Barthel Index alone, and three registers used both mRS and Barthel Index. Only two registers included a quality-of-life measure, the EQ-5D. Eight registers included a quality-of-care measure, and 26 (61.9%) registers recorded socioeconomic status or a socioeconomic status proxy, most frequently educational attainment. This scoping review found high heterogeneity of methods and definitions used by stroke registers, with low uptake of the WHO stepwise method of stroke surveillance. A drive to standardize methodology would improve the comparability of stroke data in SSA. The shared use of educational attainment by registers in our review may enable future meta-analyses of inequities in stroke in SSA. Incorporating health-related quality-of-life measures, such as EQ-5D, into stroke registers should be encouraged, bringing a patient perspective, and allow the estimation of quality-adjusted life years lost to stroke. Agreement on a standardized register methodology or further promotion and uptake of the WHO stepwise method is essential to produce comparable data to improve stroke prevention and care.

Examining the relationship between women’s empowerment and food security in low- and middle-income countries: A narrative review

Prior research has proposed women’s empowerment in agriculture as one of the strategies to mitigate household and individual food insecurity within nutrition-sensitive agriculture interventions. Yet the current evidence on this relationship is inconclusive requiring further exploration to elucidate the pathways through which women’s empowerment is associated with food security. This literature review aimed to draw insights from studies on women’s empowerment and food security and identify the related challenges and best practices in this pathway within the context of low- and middle-income countries. Scopus, PubMed, and Global Health databases were searched, as well as reference lists for articles. In total 21 articles met the inclusion criteria. Findings suggest a mixed relationship between women’s empowerment and food security and highlighted a gap in conceptualizing and operationalizing food security. To achieve sustainable food security, particularly in the aftermath of COVID-19, researchers and stakeholders must respond to the broader context of gender systems that restricts women’s rights and access to productive resources to achieve food security.

Effectiveness of chatbots in increasing uptake, intention, and attitudes related to any type of vaccination: A systematic review and meta-analysis.

This systematic review and meta-analysis analyzed and summarized the growing literature on the effectiveness of chatbot-delivered interventions in increasing uptake, intention, and attitudes related to any type of vaccination. We identified randomized controlled studies (RCTs), quasi-experimental studies, and non-experimental studies from the following platforms: PubMed, Web of Science, MEDLINE, Global Health, APA PsycInfo, and EMBASE databases. A total of 12 eligible studies published from 2019 to 2023 were analyzed and summarized. In particular, one RCT showed that a chatbot-delivered tailored intervention was more effective than a chatbot-delivered non-tailored intervention in promoting seasonal influenza vaccine uptake among older adults (50.5% versus 35.3%, p = 0.002). Six RCTs were included in the meta-analysis to evaluate the effectiveness of chatbot interventions to improve vaccination attitudes and intentions. The pooled standard mean difference (SMD) of overall attitude change was 0.34 (95% confidence intervals [CI]: 0.13, 0.55, p = 0.001). We found a non-significant trivial effect of chatbot interventions on improving intentions of vaccination (SMD: 0.11, 95% CI: -0.13, 0.34, p = 0.38). However, further evidence is needed to draw a more precise conclusion. Additionally, study participants reported high satisfaction levels of using the chatbot and were likely to recommend it to others. The development of chatbots is still nascent and rooms for improvement exist.

South Asia's unprotected poor: A systematic review of why social protection programs fail to reach their potential.

The incongruity between South Asia's economic growth and extreme poverty has led to a growing interest in social protection and subsequent implementation of anti-poverty initiatives. However, many programs have consistently fallen short of their full potential in reaching the poor. We reviewed the literature to understand the factors behind this failure. A search of EconLit, Global Health Database, MEDLINE and SocINDEX, supplemented by an external search, yielded 42 papers evaluating 23 programs. Inclusion criteria included social and political determinants of program outcomes. Articles were assessed for quality using the GRADE and GRADE CERQual criteria and analyzed using Thomas & Harding's thematic synthesis approach. We identified five themes: (1) structurally flawed program theories overlook the complexities of poverty and are rooted in simplistic cause-and-effect approaches; (2) elite capture through appropriation of benefits, powerful positioning in program implementation, and gatekeeping through relationships of patronage; (3) insufficient targeting strategies to reach the poorest; (4) neglect of gendered restrictions, hidden costs, lack of legal documentation, and physical and social exclusion; (5) active self-exclusion from social protection to maintain dignity, a perception that programs are substandard, and a lack of resources required. The review highlights the well-documented disconnect between South Asian social protection program designs and the ground realities of their 'ideal' beneficiaries. This stems from a dominance of Western-led poverty discourse that disregards the influence of caste, the challenge of effective engagement with a group whose identity remains unclear, and fast-paced funding calls that do not lend themselves to meaningful identification and collaboration with the invisible poor. We suggest this disconnect is intentional and reflects a broader power dynamic rooted in geopolitical interests and national priorities. Study limitations reflect the shortcomings of the existing literature, which largely uses quantitative research methods that fail to capture the multidimensional experiences of the poor.

Approaches for delivery of refractive and optical care services in community and primary care settings.

Uncorrected refractive error is a leading cause of vision impairment which, in most cases, can be managed with the appropriate spectacle correction. In 2021, the World Health Assembly endorsed a global target of a 40-percentage-point increase in effective coverage of refractive error by 2030. To achieve this global target, equitable access to refractive and optical services within community and primary care settings needs to be strengthened. This review will inform the development of technical guidance to support improvements in the testing and correction of refractive error among World Health Organization (WHO) member states. To determine the range of approaches for delivery of refractive and optical care services in community and primary care settings, and the methods employed for their evaluation. We searched CENTRAL, MEDLINE, Embase and Global Health databases, grey literature, and annual reports and websites of relevant organizations involved in eye-care delivery from January 2002 to November 2022 to identify approaches for refractive and optical service delivery. We included observational and interventional studies, reviews, and reports from relevant organizations related to delivering refractive services and optical services for preschool and school-aged children and adults in community and primary care settings published between January 2002 and November 2022. We searched for studies and reports published within the last 20 years because vision impairment due to uncorrected refractive error has only recently become a public health and eye health priority, therefore we did not expect to find much relevant literature until after 2002. Two review authors screened titles, abstracts and full texts, and extracted data. We resolved any discrepancies through discussion. We synthesized data, and presented results as tables, figures, and case studies. This project was led by the World Health Organization (WHO) Vision and Eye Care Programme. We identified 175 studies from searches of databases and grey literature, 146 records from company reports, and 81 records from website searches of relevant organizations that matched our inclusion criteria. Delivery approaches for refractive and optical services in community care included school-based, pharmacy, and outreach models, whereas primary care approaches comprised vision centre, health centre, and a combination of vision or health centre and door-to-door delivery. In community care, school-based and outreach approaches were predominant, while in primary care, a vision-centre approach was mainly used. In the WHO African region, the school-based and outreach approaches were mainly reported while, in the Americas, the outreach approach was mostly used. Very few approaches for service delivery were reported in the WHO Eastern Mediterranean region. Prominent gaps exist in the evaluation of the approaches, and few studies attempted to evaluate the approaches for delivery of refractive and optical care services. We comprehensively describe a range of approaches for delivery of refractive and optical services in community and primary care. Further evaluation of their effectiveness will better inform the application of these service-delivery approaches. The study outcomes will help guide WHO member states in strengthening refractive and optical services at community and primary care levels. This scoping review was supported by the Vision and Eye care Programme, World Health Organization and ATscale Global Partnership. The protocol of this scoping review was published in the Open Source Framework.

Mapping the evidence on factors related to postpartum contraception among sub-Saharan African immigrant and refugee women in the United States of America: A scoping review protocol.

Postpartum contraception is essential to sexual and reproductive health (SRH) care because it encourages healthy spacing between births, helps women avoid unwanted pregnancies, and lessens the risks of health problems for mothers and babies. Sub-Saharan African immigrant and refugee populations are rapidly increasing in the United States, and they come from a wide range of cultural, linguistic, religious, and social origins, which may pose challenges in timely access to culturally acceptable SRH care, for preventing mistimed or unwanted childbearing. The objective of this scoping review is to assess the extent of the available literature on postpartum contraception among sub-Saharan African immigrant and refugee women living in the United States. We developed preliminary search terms with the help of an expert librarian, consisting of keywords including birth intervals, birth spacing, contraception, postpartum contraception or family planning, and USA or America, and sub-Saharan African immigrants, or emigrants. The study will include the following electronic databases: PubMed/MEDLINE, PsycINFO, CINAHL, EMBASE, and the Global Health Database. The sources will include studies on postpartum care and contraceptive access and utilization among sub-Saharan African immigrants living in the US. Citations, abstracts, and full texts will be independently screened by two reviewers. We will use narrative synthesis to analyze the data using quantitative and qualitative methods. Factors associated with postpartum contraception will be organized using the domains and constructs of the PEN-3 Model as a guiding framework. This scoping review will map the research on postpartum contraception among sub-Saharan African immigrant and refugee women living in the US. We expect to identify knowledge gaps, and barriers and facilitators of postpartum contraception in this population. Based on the findings of the review, recommendations will be made for advocacy and program and policy development toward optimizing interpregnancy intervals in sub-Saharan African immigrants living in the US.

Prevalence of nonalcoholic fatty liver disease in pediatrics and adolescents: a systematic review and meta-analysis.

As childhood obesity escalates worldwide, the prevalence of nonalcoholic fatty liver disease (NAFLD) in pediatric and adolescent populations is also increasing. However, systematic studies and meta-analyses evaluating the prevalence of pediatric NAFLD remain limited. The MEDLINE, Korean Medical Database (KMBASE), Embase, Global Health, and Cochrane Library databases were searched from January 1997 to April 2023. Search terms included NAFLD or steatosis; nonalcoholic or steatohepatitis; child(ren), adolescent, or teenager; and prevalence, incidence, or epidemiology. A random-effects meta-analysis model was used to estimate the prevalence of pediatric NAFLD. A total of 2116 publications were found, of which 62 were included in the meta-analysis. Among them, 27 reported the prevalence in the general population and 39 in the obese population. The worldwide pooled prevalence of pediatric NAFLD was 13% [95% confidence interval (CI) 9-18%] in the general population and 47% (95% CI 41%-53%) in the obese population. Among 16 studies in the general population and 18 in the obese population, NAFLD prevalence varied by gender. In the general population, the prevalence of NAFLD was 15% (95% CI 8%-23%) in males and 10% (95% CI 6%-15%) in females. In the obese population, it was 54% (95% CI 46%-61%) in males and 39% (95% CI 30%-49%) in females. The global prevalence of pediatric NAFLD is rising in both the general and obese populations. Given the increasing rates of childhood obesity, epidemiological studies on the prevalence and incidence of NAFLD are needed.

Tackling syndemics by integrating infectious and noncommunicable diseases in health systems of low- and middle-income countries: A narrative systematic review.

The co-occurrence of infectious diseases (ID) and non-communicable diseases (NCD) is widespread, presenting health service delivery challenges especially in low-and middle-income countries (LMICs). Integrated health care is a possible solution but may require a paradigm shift to be successfully implemented. This literature review identifies integrated care examples among selected ID and NCD dyads. We searched PubMed, PsycINFO, Cochrane Library, CINAHL, Web of Science, EMBASE, Global Health Database, and selected clinical trials registries. Eligible studies were published between 2010 and December 2022, available in English, and report health service delivery programs or policies for the selected disease dyads in LMICs. We identified 111 studies that met the inclusion criteria, including 56 on tuberculosis and diabetes integration, 46 on health system adaptations to treat COVID-19 and cardiometabolic diseases, and 9 on COVID-19, diabetes, and tuberculosis screening. Prior to the COVID-19 pandemic, most studies on diabetes-tuberculosis integration focused on clinical service delivery screening. By far the most reported health system outcomes across all studies related to health service delivery (n = 72), and 19 addressed health workforce. Outcomes related to health information systems (n = 5), leadership and governance (n = 3), health financing (n = 2), and essential medicines (n = 4)) were sparse. Telemedicine service delivery was the most common adaptation described in studies on COVID-19 and either cardiometabolic diseases or diabetes and tuberculosis. ID-NCD integration is being explored by health systems to deal with increasingly complex health needs, including comorbidities. High excess mortality from COVID-19 associated with NCD-related comorbidity prompted calls for more integrated ID-NCD surveillance and solutions. Evidence of clinical integration of health service delivery and workforce has grown-especially for HIV and NCDs-but other health system building blocks, particularly access to essential medicines, health financing, and leadership and governance, remain in disease silos.
