Factors associated with posttraumatic stress and anxiety among the parents of babies admitted to neonatal care: a systematic review.

Background: Posttraumatic stress (PTS) and anxiety are common mental health problems among parents of babies admitted to a neonatal unit (NNU). This review aimed to identify sociodemographic, pregnancy and birth, and psychological factors associated with PTS and anxiety in this population.

Method: Studies published up to December 2022 were retrieved by searching Medline, Embase, PsychoINFO, Cumulative Index to Nursing and Allied Health electronic databases.

The impact of the Covid-19 pandemic on postnatal anxiety and posttraumatic stress: Analysis of two population-based national maternity surveys in England.

Background: Few studies have evaluated postnatal anxiety and posttraumatic stress (PTS) before and during the Covid-19 pandemic using comparable data across time. We used data from two national maternity surveys in England to explore the impact of the pandemic on prevalence and risk factors for postnatal anxiety and PTS.

Methods: Analysis was conducted using population-based surveys carried out in 2018 (n = 4509) and 2020 (n = 4611).

GC-MS analysis, molecular docking, and pharmacokinetic studies of Multidentia crassa extracts' compounds for analgesic and anti-inflammatory activities in dentistry.

Plant extracts have been useful for oral health or dentistry. However, only a few evidence-based justifications exist. This study evaluated Multidentia crassa (Hiern) Bridson & Verdc, one of the oral health-used plants in Malawi.

Machine learning algorithms for predicting determinants of COVID-19 mortality in South Africa.

Background: COVID-19 has strained healthcare resources, necessitating efficient prognostication to triage patients effectively. This study quantified COVID-19 risk factors and predicted COVID-19 intensive care unit (ICU) mortality in South Africa based on machine learning algorithms.

Methods: Data for this study were obtained from 392 COVID-19 ICU patients enrolled between 26 March 2020 and 10 February 2021.

Normative spatiotemporal fetal brain maturation with satisfactory development at 2 years.

Maturation of the human fetal brain should follow precisely scheduled structural growth and folding of the cerebral cortex for optimal postnatal function. We present a normative digital atlas of fetal brain maturation based on a prospective international cohort of healthy pregnant women, selected using World Health Organization recommendations for growth standards. Their fetuses were accurately dated in the first trimester, with satisfactory growth and neurodevelopment from early pregnancy to 2 years of age.

Contrasting speed and accuracy approaches to measure executive functions in three low-and middle-income countries.

Executive functions (EF) can be measured by tests assessing accuracy, reaction times and by computing scores which combine these two components. Interpretation issues can arise from the use of different scoring methods across studies. Given that EF measures and their scoring methods are predominantly developed and validated in high income countries, little is known about the generalisability of such methods cross- culturally.

The impact of the Covid-19 pandemic on postnatal depression: analysis of three population-based national maternity surveys in England (2014-2020).

Background: Few studies have evaluated postnatal depression before and during the Covid-19 pandemic using comparable data across time. We used data from three national maternity surveys in England to compare prevalence and risk factors for postnatal depression before and during the pandemic.

Methods: Analysis was conducted using population-based surveys carried out in 2014 (n = 4571), 2018 (n = 4509), and 2020 (n = 4611).

Family play, reading, and other stimulation and early childhood development in five low-and-middle-income countries.

This paper used longitudinal data from five studies conducted in Bangladesh, Bhutan, Cambodia, Ethiopia, and Rwanda to examine the links between family stimulation and early childhood development outcomes (N = 4904; M = 51.5; 49% girls). Results from random-effects and more conservative child-fixed effects models indicate that across these studies, family stimulation, measured by caregivers' engagement in nine activities (e.

Association between fetal abdominal growth trajectories, maternal metabolite signatures early in pregnancy, and childhood growth and adiposity: prospective observational multinational INTERBIO-21st fetal study.

Background: Obesity predominantly affects populations in high-income countries and those countries facing epidemiological transition. The risk of childhood obesity is increased among infants who had overweight or obesity at birth, but in low-resource settings one in five infants are born small for gestational age. We aimed to study the relationships between: (1) maternal metabolite signatures; (2) fetal abdominal growth; and (3) postnatal growth, adiposity, and neurodevelopment.

Effects of early-life poverty on health and human capital in children and adolescents: analyses of national surveys and birth cohort studies in LMICs.

The survival and nutrition of children and, to a lesser extent, adolescents have improved substantially in the past two decades. Improvements have been linked to the delivery of effective biomedical, behavioural, and environmental interventions; however, large disparities exist between and within countries. Using data from 95 national surveys in low-income and middle-income countries (LMICs), we analyse how strongly the health, nutrition, and cognitive development of children and adolescents are related to early-life poverty.

Geo-analysis: the distribution of community health workers in relation to the HIV prevalence in KwaZulu-Natal province, South Africa.

Background: The South African Ward Based Primary Health Care Outreach Team (WBPHCOT) policy framework states that the distribution of community health workers (CHWs) should be proportional to levels of poverty and disease within the population. We aimed to describe the spatial distribution of CHWs in relation to the prevalence of the Human Immunodeficiency Virus (HIV) which has itself been associated with poverty in previous studies.

Methods: This was a descriptive, cross-sectional study in which secondary data was used for geospatial analysis.

Prevalence of anxiety and post-traumatic stress (PTS) among the parents of babies admitted to neonatal units: A systematic review and meta-analysis.

Background: Parents of babies admitted to neonatal units (NNU) are exposed to a range of potentially distressing experiences, which can lead to mental health symptoms such as increased anxiety and post-traumatic stress (PTS). This review aimed to describe how anxiety and PTS are defined and assessed, and to estimate anxiety and PTS prevalence among parents of babies admitted to NNU.

Method: Medline, Embase, PsychoINFO, Cumulative Index to Nursing and Allied Health literature were searched to identify studies published prior to April 14, 2021.

Opportunities for technologically driven dialogical health communication for participatory interventions: Perspectives from male peer navigators in rural South Africa.

There is increasing interest in the potential to deliver participatory dialogical HIV and intimate partner violence (IPV) prevention interventions via digital platforms, though the majority of mHealth interventions have been didactic in approach. We undertook 10 in-depth interviews with male Peer Navigators (PNs) who had been extensively trained and working on a larger intervention promoting young people's sexual and reproductive rights, in rural KwaZulu-Natal. Interviews focused on their, and their peers', use of technology in their everyday lives.

A Brief Home-Based Parenting Intervention to Reduce Behavior Problems in Young Children: A Pragmatic Randomized Clinical Trial.

Importance: Behavior problems are one of the most common mental health disorders in childhood and can undermine children's health, education, and employment outcomes into adulthood. There are few effective interventions for early childhood.

Objective: To test the clinical effectiveness of a brief parenting intervention, the Video-feedback Intervention to promote Positive Parenting and Sensitive Discipline (VIPP-SD), in reducing behavior problems in children aged 12 to 36 months.

Genital and systemic immune effects of the injectable, contraceptive norethisterone enanthate (NET-EN), in South African women.

Problem: Injectable hormonal contraceptives (IHC) have been associated with altered mucosal and systemic milieu which might increase HIV risk, but most studies have focused on DMPA and not NET-EN, despite the growing popularity and lower HIV risk associated with the latter in observational studies.

Method Of Study: We used high-performance liquid chromatography in combination with tandem triple quadrupole mass spectrometry (HPLC-LC-MS/MS) to measure steroid hormones in plasma samples of CAPRISA004 study participants. Concentrations of 48 cytokines were measured in the cervicovaginal lavage (CVL) and plasma, and their expression was compared between participants with detectable NET-EN (n = 201) versus non-detectable IHC (n = 90).

Using the Emanuel Framework to Explore the Ethical Issues Raised in a Participatory Visual Research Project in Rural South Africa.

Participatory visual research can offer critical insight into the experiences of those most affected by health issues. As these methods are increasingly used to research sensitive topics, there is a need for a clear ethical framework to guide best practice on the part of researchers and research ethics committees. Here we reflect on a project where we used digital storytelling as a participatory visual methodology to explore HIV treatment adherence in rural South Africa, with a focus on the ethical issues we encountered during the lifetime of the project.

Exploring the evolution of policies for universal antiretroviral therapy and their implementation across three sub-Saharan African countries: Findings from the SHAPE study.

Universal antiretroviral therapy (ART) strategies have dramatically changed HIV programming across sub-Saharan Africa. We explored factors that influenced the development, adoption and implementation of universal ART policies in Tanzania, South Africa and Malawi. We conducted 26 key informant interviews and applied Kingdon's 'streams' model to explore how problems, policies and politics converged to provide a window of opportunity for universal ART roll-out.

Influence of evolving HIV treatment guidance on CD4 counts and viral load monitoring: A mixed-methods study in three African countries.

Little is known about how CD4 and viral load testing have evolved following implementation of universal test and treat (UTT) in African settings. We reviewed World Health Organization (WHO) guidance from 2013 to 2018, and compared it against national HIV policies in Malawi, Tanzania and South Africa. Three surveys rounds were conducted in 2013, 2016 and 2017-2018 in 33 health facilities across the three settings to assess implementation of national policies on the use of biological markers.

Formation of Lung Inducible Bronchus Associated Lymphoid Tissue Is Regulated by Expressed Determinants.

() is the causative agent of the infectious disease tuberculosis (TB), which is a leading cause of death worldwide. Approximately one fourth of the world's population is infected with . A major unresolved question is delineating the inducers of protective long-lasting immune response without inducing overt, lung inflammation.

Direct maternal deaths attributable to HIV in the era of antiretroviral therapy: evidence from three population-based HIV cohorts with verbal autopsy.

Objective: To assess whether HIV is associated with an increased risk of mortality from direct maternal complications.

Design: Population-based cohort study using data from three demographic surveillance sites in Eastern and Southern Africa.

Methods: We use verbal autopsy data, with cause of death assigned using the InSilicoVA algorithm, to describe the association between HIV and direct maternal deaths amongst women aged 20-49 years.
