There are three notable changes that have radically changed the landscape of higher education in South Africa (SA) over the past decade. These changes relate to access which is reflected in the growth of the student body, a movement towards free university education and a call for decolonisation of knowledge recently led by the #FeesMustFall movement in 2015. Academic mentoring can be a reflexive praxis to some of the reported challenges that have been associated with formal and epistemological access in higher education in South Africa. This article draws on the findings of a two-year pilot project (2015 to 2016) that explored academic mentoring within the Faculty of Engineering and Building Studies at the University of Johannesburg (UJ), South Africa. The article reflects on mentees' perceptions of the benefits of academic mentoring. The uniqueness of the article is that it highlights the value of mentoring during the transition between the first year at university and subsequent senior years of the students' academic trajectory. A survey approach using an evaluation-based questionnaire was employed in a sample of 14 (n = 14) participants in the first to fourth years of study towards a Bachelor's degree in Engineering. The perspectives of mentees were examined in terms of their experiences of participation and perceived benefits of mentoring, both academic and psychosocial. Generally, a considerable number of mentees who participated in the programme saw academic and psychosocial benefits resulting from their participation. Findings provide key considerations in support of the expansion and continuity of academic mentoring programmes in the Faculty of Engineering and Building Studies and the University at large. Academic mentoring is beneficial to all the stakeholders involved if it is done correctly. [ABSTRACT FROM AUTHOR]

Improper use of magnesium sulfate has been reported globally. Therefore, actionable findings for improving magnesium sulfate use are needed. This study aims at understanding the views of midwives towards MgSO4 use to inform an intervention whose objective is to improve MgSO4 use among the midwives.Methods: An exploratory qualitative study was conducted from July to September 2018. We conducted 10 in-depth interviews and a focus group discussion with midwives. All the interviews were audio taped and transcribed verbatim. Data were managed by NVivo version 10.0 and analyzed thematically.Results: We identified one overarching theme: “Inadequate governing approaches on management of clients on MgSO4” with corresponding subthemes; in adequate preparation on magnesium sulfate administration; inconsistent formula, regimen and guidelines/protocols on magnesium sulfate use and lack of resources.Conclusion: Midwives perceived MgSO4 use as a demanding activity due to inadequate training, inconsistent tools, and lack of resources. While periodic in-service training should be intensified to improve MgSO4 use, necessary resources should be provided, such as blood pressure machines, more midwives, and protocols.Keywords: magnesium sulfate, Malawi, midwives, perception and resources

Background: A child's cancer diagnosis and treatment are stressful for family caregivers, who may experience anxiety, depressive symptoms, and poor health-related quality of life (HRQoL) related to the care they provide., Objective: This study assessed the prevalence of anxiety, depressive symptoms, HRQoL, and associated factors among caregivers of children with cancer., Methods: A cross-sectional study was conducted on 167 caregivers of children with cancer in Malawi. A multivariate analysis was conducted to identify the determinants of anxiety, depressive symptoms, and HRQoL., Results: All 167 caregivers who consented to participate in this study completed all the questionnaires. Severe anxiety and severe depressive symptoms accounted for 17.5% and 10.2%, respectively. Being Muslim (B = 7.800, P < .001) and Pentecostal (B = 3.067, P = .023) by religious denominations was more likely to be anxious, whereas Catholic caregivers (B = 3.702, P = .033) were more likely to be depressed. Being unemployed was more likely to result in lower anxiety (B = -4.080, P = .016). Furthermore, caregivers demonstrated a lower mental health component (mean, 39.33 [SD, 6.35]), whereas being a female and aged between 31 and 40 years was more likely to result in better physical health (B = 3.962 [P = .031] and B = 3.415 [P = .020], respectively)., Conclusion: This study supports evidence that caregivers of children experience moderate and severe anxiety and depressive symptoms and poor HRQoL in Malawi., Implication for Practice: Nurses need to include psychological interventions for caregivers of children with cancer during childcare., Competing Interests: The authors have no funding or conflicts of interest to disclose., (Copyright © 2023 Wolters Kluwer Health, Inc.

Migrant nurses face many challenges as they adapt and assimilate into their new working environments. The aim of this cross-sectional study was to investigate the perceptions of work-related strain, sense of coherence and intercultural sensitivity among nurses who were employed at a public mental health facility in Qatar. We used three self-report questionnaires: the work-related strain inventory, sense of coherence scale and an intercultural sensitivity scale. A cohort of 136 nurses voluntarily engaged in the study. The majority of participants were male, migrated from South Asia and were in their mid-30s. The study found that both sense of coherence and intercultural sensitivity were inversely proportional to work-related strain. Work-related strain was found to be lower than expected; the factors that appear to protect against work-related strain include longer clinical experience, a high sense of coherence, and intercultural sensitivity. Additionally, greater age and extended clinical experience, combined with a history of work in three or more countries, associated with higher scores on the sense of coherence scale. Lastly, being female, having a postgraduate degree and holding a senior-level position were associated with increased intercultural sensitivity. As nurses' migration across national and international borders increases in response to global demand, this study has important implications for nursing administrators, educators and policymakers in relation to the development and implementation of strategies to enhance nurses' sense of coherence and intercultural sensitivity and prevent work-related strain.

Artemisinin-based combination therapy (ACT) is the first-line recommended treatment for uncomplicated malaria. Pharmacokinetic (PK) properties in pregnant women are often based on small studies and need to be confirmed and validated in larger pregnant patient populations. This study aimed to evaluate the PK properties of amodiaquine and its active metabolite, desethylamodiaquine, and piperaquine in women in their second and third trimester of pregnancy with uncomplicated P. falciparum infections. Eligible pregnant women received either artesunate-amodiaquine (200/540 mg daily, n = 771) or dihydroartemisinin-piperaquine (40/960 mg daily, n = 755) for 3 days (NCT00852423). Population PK properties were evaluated using nonlinear mixed-effects modeling, and effect of gestational age and trimester was evaluated as covariates. 1071 amodiaquine and 1087 desethylamodiaquine plasma concentrations, and 976 piperaquine plasma concentrations, were included in the population PK analysis. Amodiaquine concentrations were described accurately with a one-compartment disposition model followed by a two-compartment disposition model of desethylamodiaquine. The relative bioavailability of amodiaquine increased with gestational age (1.25% per week). The predicted exposure to desethylamodiaquine was 2.8%-32.2% higher in pregnant women than that reported in non-pregnant women, while day 7 concentrations were comparable. Piperaquine concentrations were adequately described by a three-compartment disposition model. Neither gestational age nor trimester had significant impact on the PK of piperaquine. The predicted exposure and day 7 concentrations of piperaquine were similar to that reported in non-pregnant women. In conclusion, the exposure to desethylamodiaquine and piperaquine was similar to that in non-pregnant women. Dose adjustment is not warranted for women in their second and their trimester of pregnancy., (© 2024 The Author(s).

Background: Low levels of physical activity in high- to low-income countries, including South Africa, pose a great risk of cardiovascular-related diseases., Aim: This study aimed to assess and compare the physical fitness profile among children., Setting: The study setting comprised rural and urban primary school learners in the Eastern Cape province, South Africa., Methods: A cross-sectional study was adopted utilising a randomly selected sample of boys and girls aged 9-14 years. Physical fitness measures were assessed using the Euro-fit test battery. Some parametric tests were used for mean comparisons of the various anthropometric measurements and physical fitness characteristics across demographics., Results: The sample consisted of 870 primary school learners. The average weight and height of the sample were 39.29 ± 10.34 kg and 144.06 ± 10.81 cm, respectively, with a mean body mass index (BMI) of 18.80 ± 4.11 kg/m 2 . The results showed that boys reported significantly high levels of physical fitness. Sit-ups ( p ≤ 0.001) and VO2 max ( p ≤ 0.001) significantly increase with age, while all the physical fitness measures were significantly higher among rural-based learners., Conclusion: Rural-based learners and boys generally had better physical fitness performance than their peers. The effect of gender and place of residence should be considered when designing physical fitness interventions., Contribution: This study adds to the existing body of knowledge about the effect of demographic factors on the physical fitness profile of children, where boys and rural-based learners are reported to be more physically fit than their counterparts., Competing Interests: The authors declare that they have no financial or personal relationships that may have inappropriately influenced them in writing this article., (© 2024.

Background: The level, direction or presence of the relationship between perceived physical activity (PA) participation and physical fitness (PF) in children may differ by gender and this will assist in designing gender-specific interventions to promote PA participation, which in turn improves PF levels., Aim: This study aimed to establish the moderating effect of gender on the relationship between perceived PA participation and PF., Method: A cross-sectional study was conducted with a cohort of 870 primary school children aged 9-14 years old. Perceived PA participation was measured using the PAQ-C questionnaire while PF levels were measured using cardiorespiratory endurance (i.e. VO2 max)., Results: The results showed significant gender differences for perceived PA participation levels ( t = -3.40, p ≤ 0.001) and PF ( t = -11.59, p ≤ 0.001), with boys reporting higher levels than the girls. Perceived PA participation had a positive, weak and statistically significant correlation with PF ( r = 0.251; p ≤ 0.001). Gender significantly moderates the relationship between perceived PA participation and PF (β 3 = 3.518; 95% confidence interval [CI]: 0.642 to 6.395; p = 0.017)., Conclusion: The moderating effect of gender on the relationship between perceived PA participation and PF highlights the differences in physiology as well as the societal PA associated roles played by boys and girls., Contribution: The study has established that the relationship between perceived PA participation and PF is more pronounced among boys than girls., Competing Interests: The authors declare that they have no financial or personal relationships that may have inappropriately influenced them in writing this article., (© 2024.

Background:  Waist-related measures are commonly used to classify central adiposity and related comorbidities. This classification may be essential among children, as it may identify the risk of future non-communicable diseases., Methods:  A cross-sectional study was conducted in the Eastern Cape province, South Africa, among 459 primary school learners aged 9-14 years. Height, weight and waist circumference (WC) were measured using standardised techniques recommended by World Health Organization (WHO). The anthropometric measurements, including body mass index (BMI), WC, waist-to-hip ratio (WHR) and waist-to-height ratio (WHtR) were computed and evaluated., Results:  Most participants were girls (57.70%) with an average age of 11.20 ± 1.60 years. The average weight was 38.81 kg ± 10.49 kg with an average height of 144.16 (standard deviation [s.d.] = 10.37) cm. The sample had a BMI of 18.41 kg/m2 (s.d. = 3.19). The results showed, on average, WC of 62.10 cm ± 8.12 cm, WHR of 0.82 ± 0.15 and WHtR of 0.44 ± 0.05. Girls reported significantly higher BMI, WC and WHtR. Based on WHtR, the results showed the acceptable ability to classify children according to abdominal obesity, thus identifying their risk for comorbidities., Conclusion:  Overall body fat indicated by BMI and central obesity shown by waist-related anthropometric measures can play a significant role in classifying children in terms of their risk of comorbidities.Contribution: To prevent the risks of metabolic diseases in childhood, it is necessary to detect abdominal obesity early using WC-based anthropometric measurements, especially WHtR, to identify those at risk.

Relative to neighboring countries, Zambia has among the most progressive abortion policies, but numerous sociopolitical constraints inhibit knowledge of pregnancy termination rights and access to safe abortion services. Multistage cluster sampling was used to randomly select 1,486 women aged 15-44 years from households in three provinces. We used latent class analysis (LCA) to partition women into discrete groups based on patterns of endorsed support for legalized abortion on six socioeconomic and health conditions. Predictors of probabilistic membership in latent profiles of support for legal abortion services were identified through mixture modeling. A three-class solution of support patterns for legal abortion services emerged from LCA: (1) legal abortion opponents (∼58 percent) opposed legal abortion across scenarios; (2) legal abortion advocates (∼23 percent) universally endorsed legal protections for abortion care; and (3) conditional supporters of legal abortion (∼19 percent) only supported legal abortion in circumstances where the pregnancy threatened the fetus or mother. Advocates and Conditional supporters reported higher exposure to family planning messages compared to opponents. Relative to opponents, advocates were more educated, and Conditional supporters were wealthier. Findings reveal that attitudes towards abortion in Zambia are not monolithic, but women with access to financial/social assets exhibited more receptive attitudes towards legal abortion., (© 2024 The Population Council, Inc.)

Background: Studies have shown that caregivers of children with cancer experience challenges when caring for their children. To date, no studies have examined the experience of caregivers of children with cancer in Malawi, a low-income country in sub-Saharan Africa. Hence, this study aimed to explore the experiences of caregivers of Malawian children receiving cancer treatment., Methods: This explorative qualitative study used semi-structured interviews to collect data from 22 caregivers of children receiving cancer treatment. The data were analysed using qualitative content analysis., Results: Five themes emerged from the QCA. The caregivers perceived their children's cancer as a burden, a form of psychological torture and a disruptor of family routines and social lifestyles. They also reported self-isolation due to the stigma that they faced in the course of caring for their children and a need for informational, psychosocial, spiritual and financial support., Conclusion: Caregivers of Malawian children with cancer experience physical and psychosocial challenges as they are caring for their children with cancer. Developing appropriate interventions would enable nurses to offer optimal support to these caregivers in dealing with these challenges and meeting their needs effectively., (© 2024 The Authors.

Abstract: Key populations (KPs) experience suboptimal outcomes along the HIV care and prevention continua, but there is limited study of the challenges service providers encounter delivering HIV services to KPs, particularly in settings like Zambia, where provision of these services remains legally ambiguous. Seventy-seven providers completed in-depth interviews exploring constraints to HIV service delivery for KPs and recommendations for improving access and care quality. Thematic analysis identified salient challenges and opportunities to service delivery and quality of care for KPs, spanning interpersonal, institutional, and structural domains. Limited provider training in KP-specific needs was perceived to influence KP disclosure patterns in clinical settings, impeding service quality. The criminalization of KP sexual and drug use behaviors, coupled with perceived institutional and legal ambiguities to providing HIV services to KPs, cultivated unwelcoming service delivery environments for KPs. Findings elucidate opportunities for improving HIV service delivery/quality, from decentralized care to expanded legal protections for KPs and service providers., (Copyright © 2023 Association of Nurses in AIDS Care.)

Importance: There is a gap in the evidence regarding nature-based interventions (NBIs) for children with autism spectrum disorder (ASD)., Objective: To systematically review and meta-analyze available evidence on the health-related outcomes in NBIs for children with ASD., Data Sources: The Cumulative Index to Nursing and Allied Health Literature, Cochrane, Embase, Emcare, Education Resources Information Center, Global Health, MEDLINE, PsycInfo, SPORTDiscus, and Web of Science were searched from inception until May 2023. Google Scholar and references from included studies were searched for additional studies., Study Selection: Included studies were randomized clinical trials (RCTs), controlled studies, and single-group before-and-after studies that reported health-related outcomes., Data Extraction and Synthesis: This review adhered to the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) reporting guidelines. Random-effects meta-analyses were used to synthesize the data. The findings of studies that were ineligible for meta-analysis were summarized according to the Synthesis Without Meta-analysis (SWIM) reporting guidelines., Main Outcomes and Measures: The outcomes of interest were health-related outcomes (ie, social functioning, behavioral functioning, emotional functioning, sensory functioning) and the self-reported well-being of children with ASD., Results: A total of 24 studies with 717 participants (mean age range, 5.3 to 17.8 years; 141 [21.9%] female) were included. A meta-analysis from 13 studies indicated a significant negative moderate association between NBIs and social communication (standardized mean difference [SMD], -0.59; 95% CI, -0.85 to -0.34). For behavioral functioning outcomes, NBIs showed a significant moderate association with reduced hyperactivity (SMD, -0.56; 95% CI, -0.86 to -0.26) and a small to moderate association with reduced irritability (SMD, -0.49; 95% CI, -0.79 to -0.19). For sensory functioning, NBIs were significantly associated with improved inattention and distractibility (SMD, 1.13; 95% CI, 0.67 to 1.60). Significant moderate associations were observed in sensory seeking (SMD, 0.77; 95% CI, 0.33 to 1.22; P < .001; I2 = 0%) and sensory sensitivity (SMD, 0.56; 95% CI, 0.12 to 1.00; P = .01; I2 = 0%). Heterogeneity of the intervention effects was not high, and I2 ranged from 0% to 67%., Conclusions and Relevance: The findings of this systematic review and meta-analysis suggested an association of NBIs in group-based recreational therapy with experiential learning with positive short-term outcomes on sensory, social, and behavioral functioning for children with ASD. Future evidence using robust study design to aid the health and functional trajectories of children with ASD is recommended.

Background: Low physical activity (PA) participation levels and increasing non-communicable diseases in children are concerning in South Africa and globally., Objectives: We sought to assess the mediating role of perceived social support factors on the relationship between PA enjoyment and PA levels among rural, peri-urban and urban school children., Method: A cross-sectional study was adopted to assess peer, family and teacher encouragement as mediators on the relationship between perceived PA enjoyment and perceived physical activity participation among children, using the Physical Activity Questionnaire for Older Children (PAQ-C). The sample comprised a random sample of primary school learners aged 9-14 years., Results: The sample consisted of 870 primary school learners with a mean age of 11.0 ± 1.49 years. Most participants were girls ( n = 519; 59.7%). The findings suggest low levels of perceived PA participation (mean = 2.33, standard deviation [s.d.]: 0.43). Peer (β = 0.0187, 95% confidence interval [CI]: 0.0088, 0.0307), family (β = 0.0280, 95% CI: 0.0155, 0.0425) and teacher (β = 0.0242, 95% CI: 0.0127, 0.0378) encouragement partially mediates the relationship between perceived PA enjoyment and perceived PA participation. Family encouragement (β = 0.0158, 95% CI: 0.0017, 0.0311) has the most considerable mediating effect, followed by teacher encouragement (β = 0.0125, 95% CI: 0.0010, 0.0269)., Conclusion: The findings demonstrated low levels of perceived PA participation in school learners. Therefore, we recommends including social factors as mediators in PA intervention programmes in primary schools., Clinical Implications: Social support factors as mediators on the relationship between PA enjoyment and PA participation among children may improve children's PA participation levels and help prevent non-communicable diseases in future., Competing Interests: The authors declare that they have no financial or personal relationships that may have inappropriately influenced them in writing this article., (© 2023.

Purpose: Psychoeducation interventions (PEIs) have been used as an adjunct treatment for negative psychological outcomes in caregivers of children with cancer. This systematic review and meta-analysis aimed to evaluate the evidence on the effectiveness of PEIs in reducing anxiety and depressive symptoms and improving health-related quality of life (HRQoL) and coping skills in caregivers of children with cancer., Method: Ten English databases were searched to identify studies on PEIs for caregivers of children with cancer. Studies inclusion criteria were as follows: (1) participants who were caregivers of children with cancer receiving treatment; (2) psychoeducational interventions assessing anxiety, depressive symptoms, HRQoL, and coping outcomes; and (3) usual care, waitlist, or active control as a control group. Meta-analysis and narrative synthesis were used to analyse data., Results: Fourteen randomised control trials were included. PEIs have a beneficial effect on anxiety levels (SMD: -0.59, 95% CI [-0.92, -0.25], p = 0.0007), quality of life (SMD: -0.31, 95% CI [-0.00, -0.61], p = 0.05) and depressive symptoms (SMD: -1.18, 95% CI [-2.08, -0.28], p = 0.01) immediately post-intervention. The effect of PEIs was maintained at long-term follow-up on depressive symptoms (SMD: -0.52, 95% CI [-1.54, -0.36], p = 0.0004). Similarly, the synthesised data suggest that PEIs are effective in improving coping skills., Conclusion: The review provides evidence that PEIs effectively reduce negative psychological outcomes and improve coping skills in caregivers of children with cancer. However, due to methodological flaws and heterogeneity of the interventions evaluated, more research is needed to determine the most effective PEI design and improve the quality of evidence., (© 2023 The Authors.

Background: In Zambia, half of children and adolescents living with HIV (CALWH) on antiretroviral therapy (ART) are virologically unsuppressed. Depressive symptoms are associated with ART nonadherence but have received insufficient attention as mediating factors in the relationship between HIV self-management and household-level adversities. We aimed to quantify theorized pathways from indicators of household adversity to ART adherence, partially mediated by depressive symptoms, among CALWH in 2 Zambian provinces., Setting: In July-September 2017, we enrolled 544 CALWH aged 5-17 years and their adult caregivers into a year-long prospective cohort study., Methods: At baseline, CALWH-caregiver dyads completed an interviewer-administered questionnaire, which included validated measures of recent (past 6 months) depressive symptomatology and self-reported past-month ART adherence (never versus sometimes or often missing medication doses). We used structural equation modeling with theta parameterization to identify statistically significant ( P < 0.05) pathways from household adversities (past-month food insecurity and caregiver self-reported health) to depression (modeled latently), ART adherence, and poor physical health in the past 2 weeks., Results: Most CALWH (mean age: 11 years, 59% female) exhibited depressive symptomatology (81%). In our structural equation model, food insecurity significantly predicted elevated depressive symptomatology ( ß = 0.128), which was associated inversely with daily ART adherence ( ß = -0.249) and positively with poor physical health ( ß = 0.359). Neither food insecurity nor poor caregiver health was directly associated with ART nonadherence or poor physical health., Conclusions: Using structural equation modeling, we found that depressive symptomatology fully mediated the relationship between food insecurity, ART nonadherence, and poor health among CALWH., Competing Interests: The authors have no conflicts of interest to disclose., (Copyright © 2023 Wolters Kluwer Health, Inc.

In areas of moderate to intense Plasmodium falciparum transmission, malaria in pregnancy remains a significant cause of low birth weight, stillbirth, and severe anaemia. Previously, fetal sex has been identified to modify the risks of maternal asthma, pre-eclampsia, and gestational diabetes. One study demonstrated increased risk of placental malaria in women carrying a female fetus. We investigated the association between fetal sex and malaria in pregnancy in 11 pregnancy studies conducted in sub-Saharan African countries and Papua New Guinea through meta-analysis using log binomial regression fitted to a random-effects model. Malaria infection during pregnancy and delivery was assessed using light microscopy, polymerase chain reaction, and histology. Five studies were observational studies and six were randomised controlled trials. Studies varied in terms of gravidity, gestational age at antenatal enrolment and bed net use. Presence of a female fetus was associated with malaria infection at enrolment by light microscopy (risk ratio 1.14 [95% confidence interval 1.04, 1.24]; P = 0.003; n = 11,729). Fetal sex did not associate with malaria infection when other time points or diagnostic methods were used. There is limited evidence that fetal sex influences the risk of malaria infection in pregnancy., (© 2023. The Author(s).)

Preterm birth is a leading cause of death in children under five years of age. We hypothesized that sequential disruptions to inflammatory and angiogenic pathways during pregnancy increase the risk of placental insufficiency and spontaneous preterm labor and delivery. We conducted a secondary analysis of inflammatory and angiogenic analytes measured in plasma samples collected across pregnancy from 1462 Malawian women. Women with concentrations of the inflammatory markers sTNFR2, CHI3L1, and IL18BP in the highest quartile before 24 weeks gestation and women with anti-angiogenic factors sEndoglin and sFlt-1/PlGF ratio in the highest quartile at 28-33 weeks gestation had an increased relative risk of preterm birth. Mediation analysis further supported a potential causal link between early inflammation, subsequent angiogenic dysregulation detrimental to placental vascular development, and earlier gestational age at delivery. Interventions designed to reduce the burden of preterm birth may need to be implemented before 24 weeks of gestation., Competing Interests: The authors declare no competing interests., (Crown Copyright © 2023.)

Purpose of Review: People who sell sex remain at disproportionate risk of acquiring HIV and should be prioritized for evidence-based HIV prevention programmes delivered at sufficient scale and intensity for effectiveness. Although new biomedical tools are becoming available, many basic lessons learned early in the HIV pandemic remain salient today and need renewed attention., Recent Findings: New preexposure prophylaxis formulations, distribution systems, and delivery mechanisms are being successfully trialled and implemented, adding to well established prevention tools such as male and female condoms and lubricants. The importance of social support networks and community ownership of programmes has been consistently reaffirmed. Serious challenges remain in optimizing HIV prevention for sex workers, including providing services at the scale and intensity necessary for population level impact, addressing culturally sensitive issues of gender identity and sexual orientation, and protecting adolescents and young people who may sell sex. Pervasive social stigma, often reinforced by criminalization and police harassment, further constrain sex workers' access to available services and prevention tools., Summary: Meaningful community engagement and addressing the multiple social determinants of vulnerability at individual, community, and structural levels remain at the core of preventing HIV among people involved in selling sex., (Copyright © 2022 Wolters Kluwer Health, Inc.

Orphaned and vulnerable children (OVC) are not only affected by, but also rendered at-risk of, HIV due to overlapping deficits in protective assets, from school to household financial security. Drawing from a protective deficit framework, this study examines correlates of sexual risk - including multiple sexual partnerships, unprotected sex, and age at sexual debut - among OVC aged 13-17 years in Zambia. In May-October 2016, a two-stage stratified random sampling design was used to recruit OVC and their adult caregivers (N = 2,034) in four provinces. OVC-caregiver dyads completed a structured interview addressing household characteristics, protective assets (i.e. finances, schooling, and nutrition), and general health and wellbeing. Associations of factors derived from the multi-component protective deficits framework were examined using multivariable ordered logistic regression, comparing sexually inexperienced OVC to those with a sexual debut and reporting ≥1 sexual behavior(s). A sub-analysis of older (ages 15-17) OVC identified correlates of early (before age 15) and later (at or after age 15) sexual debut using multinomial logistic regression. Among 735 OVC aged 13-17, 14% reported a sexual debut, among whom 14% and 22% reported 2+ past-year partners and non-condom last sex, respectively. Older age (Adjusted Odds Ratio [aOR] = 2.08, 95% Confidence Interval [CI] 1.32-3.27), male sex (aOR = 1.90, CI 1.22-2.96), not having a birth certificate (aOR = 2.05, CI 1.03-4.09), out-of-school status (aOR = 2.63, CI 1.66-4.16), and non-household labor (aOR = 1.84, CI 1.01-3.38) were significantly associated with higher sexual risk. Male sex was the only factor significantly associated with early sexual debut in multivariable analysis. Sexual risk-reduction strategies require age- and sex-specific differentiation and should be prioritized for OVC in financially distressed households., Competing Interests: Disclosure statement No potential conflict of interest was reported by the author(s).

Background: Hypertension is among the most commonly diagnosed non-communicable diseases in Africa, and studies have demonstrated a high prevalence of hypertension among individuals with HIV. Despite high prevalence, there has been limited attention on the clinical outcomes of hypertension treatment in this population., Objective: We sought to characterize rates of and factors associated with blood pressure control over one year among individuals on antiretroviral therapy (ART) and antihypertensive medications., Methods: We performed a prospective observational cohort study at an HIV clinic in Malawi. We defined uncontrolled hypertension as a systolic blood pressure ≥140 mm Hg and/or diastolic blood pressure ≥90 mm Hg at two or more follow-up visits during the year, while controlled hypertension was defined as <140 mm Hg systolic and <90 mm Hg diastolic at all visits, or at all but one visit. We calculated an antihypertensive non-adherence score based on self-report of missed doses at each visit (higher score = worse adherence) and used rank sum and chi-square tests to compare sociodemographic and clinical factors (including adherence) associated with blood pressure control over the year., Results: At study entry, 158 participants (23.5%) were on antihypertensive medication; participants had a median age of 51.0 years, were 66.5% female, and had a median of 6.9 years on ART. 19.0% (n = 30) achieved blood pressure control over the year of follow-up. Self-reported non-adherence to hypertension medications was the only factor significantly associated with uncontrolled blood pressure. The average non-adherence score for those with controlled blood pressure was 0.22, and for those with uncontrolled blood pressure was 0.61 (p = 0.009)., Conclusions: Adults living with HIV and hypertension in our cohort had low rates of blood pressure control over one year associated with self-reported non-adherence to antihypertensive medications. Given the high prevalence and incidence of hypertension, interventions to improve blood pressure control are needed to prevent associated long-term cardio- and cerebrovascular morbidity and mortality., Competing Interests: The authors have no competing interests to declare., (Copyright: © 2021 The Author(s).)

Background: Malaria during pregnancy is a major contributor to the global burden of adverse birth outcomes including fetal growth restriction, preterm birth, and fetal loss. Recent evidence supports a role for angiogenic dysregulation and perturbations to placental vascular development in the pathobiology of malaria in pregnancy. The Angiopoietin-Tie2 axis is critical for placental vascularization and remodeling. We hypothesized that disruption of this pathway would contribute to malaria-induced adverse birth outcomes., Methods: Using samples from a previously conducted prospective cohort study of pregnant women in Malawi, we measured circulating levels of angiopoietin-1 (Angpt-1) and Angpt-2 by Luminex (n=1392). We used a preclinical model of malaria in pregnancy (Plasmodium berghei ANKA [PbA] in pregnant BALB/c mice), genetic disruption of Angpt-1 (Angpt1 +/- mice), and micro-CT analysis of placental vasculature to test the hypothesis that disruptions to the Angpt-Tie2 axis by malaria during pregnancy would result in aberrant placental vasculature and adverse birth outcomes., Findings: Decreased circulating levels of Angpt-1 and an increased ratio of Angpt-2/Angpt-1 across pregnancy were associated with malaria in pregnancy. In the preclinical model, PbA infection recapitulated disruptions to the Angiopoietin-Tie2 axis resulting in reduced fetal growth and viability. Malaria decreased placental Angpt-1 and Tie2 expression and acted synergistically with reduced Angpt-1 in heterozygous dams (Angpt1 +/- ), to worsen birth outcomes by impeding vascular remodeling required for placental function., Interpretation: Collectively, these data support a mechanistic role for the Angpt-Tie2 axis in malaria in pregnancy, including a potential protective role for Angpt-1 in mitigating infection-associated adverse birth outcomes., Funding: This work was supported by the Canadian Institutes of Health Research (CIHR), Canada Research Chair, and Toronto General Research Institute Postdoctoral Fellowship Award. The parent trial was supported by the European & Developing Countries Clinical Trials Partnership and the Malaria in Pregnancy Consortium, which was funded by the Bill & Melinda Gates Foundation.

Youth-friendly health care delivery models are needed to address the complex health care needs of adolescent girls and young women (AGYW). The aim of this study is to explore the lived experiences of AGYW seeking comprehensive HIV and sexual and reproductive health (SRH) care and to elicit their preferences for integrated health care services. We conducted in-depth interviews and focus group discussions in Lusaka, Zambia among 69 AGYW aged 10-20 who were HIV-negative or of unknown status and 40 AGYW aged 16-24 living with HIV. The data were coded through deductive and inductive processes and analyzed thematically using modified World Health Organization (WHO) dimensions of quality for youth-friendly services. AGYW expressed preference for one-stop clinics with integrated services that could provide HIV services along with other services such as pregnancy testing and family planning. AGYW also wanted information on staying healthy and approaches to prevent disease which could be delivered in the community setting such as youth clubs. An integrated clinic should address important attributes to AGYW including short wait time, flexible opening hours, assurance of confidentiality and positive staff attitudes. Youth-friendly, integrated care delivery models that incorporate AGYW preferences may foster linkages to care and improve outcomes among vulnerable AGYW., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2021 Edwards, Roberts, Chelwa, Phiri, Nyblade, Mulenga, Brander, Musheke, Mbizvo and Subramanian.)

Background: Annually 125 million pregnancies are at risk of malaria infection. However, the impact of exposure to malaria in pregnancy on neurodevelopment in children is not well understood. We hypothesized that malaria in pregnancy and associated maternal immune activation result in neurodevelopmental delay in exposed offspring., Methods and Findings: Between April 2014 and April 2015, we followed 421 Malawian mother-baby dyads (median [IQR] maternal age: 21 [19, 28] years) who were previously enrolled (median [IQR] gestational age at enrollment: 19.7 [17.9, 22.1] weeks) in a randomized controlled malaria prevention trial with 5 or 6 scheduled assessments of antenatal malaria infection by PCR. Children were evaluated at 12, 18, and/or 24 months of age with cognitive tests previously validated in Malawi: the Malawi Developmental Assessment Tool (MDAT) and the MacArthur-Bates Communicative Development Inventories (MCAB-CDI). We assessed the impact of antenatal malaria (n [%] positive: 240 [57.3]), placental malaria (n [%] positive: 112 [29.6]), and maternal immune activation on neurocognitive development in children. Linear mixed-effects analysis showed that children exposed to antenatal malaria between 33 and 37 weeks gestation had delayed language development across the 2-year follow-up, as measured by MCAB-CDI (adjusted beta estimate [95% CI], -7.53 [-13.04, -2.02], p = 0.008). Maternal immune activation, characterized by increased maternal sTNFRII concentration, between 33 and 37 weeks was associated with lower MCAB-CDI language score (adjusted beta estimate [95% CI], -8.57 [-13.09, -4.06], p < 0.001). Main limitations of this study include a relatively short length of follow-up and a potential for residual confounding that is characteristic of observational studies., Conclusions: This mother-baby cohort presents evidence of a relationship between malaria in pregnancy and neurodevelopmental delay in offspring. Malaria in pregnancy may be a modifiable risk factor for neurodevelopmental injury independent of birth weight or prematurity. Successful interventions to prevent malaria during pregnancy may reduce the risk of neurocognitive delay in children., Competing Interests: The authors have declared that no competing interests exist.

Background: Climate-induced disruptions like drought can destabilize household and community livelihoods, particularly in low- and middle-income countries. This qualitative study explores the impact of severe and prolonged droughts on gendered livelihood transitions, women's social and financial wellbeing, and sexual and reproductive health (SRH) outcomes in two Zambian provinces., Methods: In September 2020, in-depth interviews (n = 20) and focus group discussions (n = 16) with 165 adult women and men in five drought-affected districts, as well as key informant interviews (n = 16) with civic leaders and healthcare providers, were conducted. A team-based thematic analysis approach, guided by the Framework Method, was used to code transcript text segments, facilitating identification and interpretation of salient thematic patterns., Results: Across districts, participants emphasized the toll drought had taken on their livelihoods and communities, leaving farming households with reduced income and food, with many turning to alternative income sources. Female-headed households were perceived as particularly vulnerable to drought, as women's breadwinning and caregiving responsibilities increased, especially in households where women's partners out-migrated in search of employment prospects. As household incomes declined, women and girls' vulnerabilities increased: young children increasingly entered the workforce, and young girls were married when families could not afford school fees and struggled to support them financially. With less income due to drought, many participants could not afford travel to health facilities or would resort to purchasing health commodities, including family planning, from private retail pharmacies when unavailable from government facilities. Most participants described changes in fertility intentions motivated by drought: women, in particular, expressed desires for smaller families, fearing drought would constrain their capacity to support larger families. While participants cited some ongoing activities in their communities to support climate change adaptation, most acknowledged current interventions were insufficient., Conclusions: Drought highlighted persistent and unaddressed vulnerabilities in women, increasing demand for health services while shrinking household resources to access those services. Policy solutions are proposed to mitigate drought-induced challenges meaningfully and sustainably, and foster climate resilience., (© 2021. The Author(s).)

This paper summarises the impact of a new triage process on referral prioritisation and waiting times in a community specialist child and adolescent mental health service (CAMHS) in Qatar. The process involves initial review of referrals by a CAMHS nurse to ensure that there is adequate clinical information, obtaining additional information from patients/families and referring clinicians by the psychiatric triage team, when necessary, followed by prioritisation and allocation of accepted referrals. The new process reduced the acceptance of inappropriate referrals, ensured prioritisation of referrals and significantly improved the service's compliance with waiting-time deadlines., Competing Interests: None., (© The Author(s) 2021.)

Background: Improving sleep quality and reducing depressive symptoms may be target mechanisms for intervention-based research aimed at reducing cardiometabolic risk in low-income communities. This study assessed the effects of exercise training on depressive symptoms and sleep in obese women for a low socioeconomic community. The secondary aim explored associations between changes in depressive symptoms and sleep with changes in cardiorespiratory fitness and cardiometabolic risk factors., Methods: Participants were randomized into exercise (n = 20) or control (n = 15) groups. The exercise group completed 12 weeks of combined resistance and aerobic training (40-60 min, 4 d/wk), and the control group maintained habitual diet and activity. Preintervention and postintervention testing included questionnaires on symptoms of depression, psychological distress, and sleep quality. Sedentary time, peak oxygen consumption, body mass index, and insulin sensitivity were measured objectively. Sleep duration (accelerometry) was assessed at preintervention and weeks 4, 8, and 12., Results: Exercise training reduced depressive symptoms (P = .002) and improved sleep quality (P < .001) and sleep efficiency (P = .005). Reduced depressive symptoms were associated with improved peak oxygen consumption (rho = -.600, P < .001), and improved sleep quality correlated with reduced sedentary time (rho = .415, P = .018)., Conclusion: These results highlight the potential for community-based exercise interventions to simultaneously address multiple comorbidities in a low-income setting.

Background: Children and youth are profoundly impacted groups in Zambia's HIV epidemic. To evaluate delivery of integrated psychosocial, economic strengthening, and clinical services to HIV-affected households through the Zambia Family (ZAMFAM) Project, a prospective cohort study compared socio-economic, psychosocial, and health outcomes among ZAMFAM beneficiaries to non-beneficiaries., Methods: In July-October 2017, 544 adolescents living with HIV (ALHIV) aged 5-17 years and their adult caregivers were recruited from Central (ZAMFAM implementation sites) and Eastern (non-intervention sites) Provinces. Structured interviews at baseline and one-year follow-up assessed household characteristics, socio-economic wellbeing, and health service utilization. Poisson regression with generalized estimating equations measured one-year changes in key health and socio-economic indicators, comparing ZAMFAM beneficiaries to non-beneficiaries., Results: Overall, 494 households completed two rounds of assessment (retention rate: 91%) Among ALHIV, improvements in current antiretroviral therapy use over time (Adjusted Prevalence Rate Ratio [aPRR] = 1.06, 95% Confidence Interval [95% CI]: 1.01-1.11) and reductions in non-household labor (aPRR = 0.44, 95% CI: 0.20-0.99) were significantly larger among ZAMFAM beneficiaries than non-beneficiaries. For caregivers, receiving ZAMFAM services was associated with significant reductions in HIV-related stigma (aPRR = 0.49, 95% CI: 0.28-0.88) and perceived negative community attitudes towards HIV (aPRR = 0.77, 95% CI: 0.62-0.96). Improvements in caregiver capacity to pay for unexpected (aPRR = 1.54, 95% CI: 1.17-2.04) and food-related expenses (aPRR = 1.48, 95% CI: 1.16-1.90), as well as shared decision-making authority in household spending (aPRR = 1.41, 95% CI: 1.04-1.93) and self-reported good or very good health status (aPRR = 1.46, 95% CI: 1.14-1.87), were also significantly larger among ZAMFAM beneficiaries., Conclusions: Significant improvements in caregivers' financial capacity were observed among households receiving ZAMFAM services, with few changes in health or wellbeing among ALHIV. Integrated service-delivery approaches like ZAMFAM may yield observable socio-economic improvements in the short-term. Strengthening community-based delivery of psychosocial and health support to ALHIV is encouraged., Competing Interests: The authors have declared that no competing interests exist.

Background: Malaria in pregnancy affects both the mother and the fetus. However, evidence supporting treatment guidelines for uncomplicated (including asymptomatic) falciparum malaria in pregnant women is scarce and assessed in varied ways. We did a systematic literature review and individual patient data (IPD) meta-analysis to compare the efficacy and tolerability of different artemisinin-based or quinine-based treatments for malaria in pregnant women., Methods: We did a systematic review of interventional or observational cohort studies assessing the efficacy of artemisinin-based or quinine-based treatments in pregnancy. Seven databases (MEDLINE, Embase, Global Health, Cochrane Library, Scopus, Web of Science, and Literatura Latino Americana em Ciencias da Saude) and two clinical trial registries (International Clinical Trials Registry Platform and ClinicalTrials.gov) were searched. The final search was done on April 26, 2019. Studies that assessed PCR-corrected treatment efficacy in pregnancy with follow-up of 28 days or more were included. Investigators of identified studies were invited to share data from individual patients. The outcomes assessed included PCR-corrected efficacy, PCR-uncorrected efficacy, parasite clearance, fever clearance, gametocyte development, and acute adverse events. One-stage IPD meta-analysis using Cox and logistic regression with random-effects was done to estimate the risk factors associated with PCR-corrected treatment failure, using artemether-lumefantrine as the reference. This study is registered with PROSPERO, CRD42018104013., Findings: Of the 30 studies assessed, 19 were included, representing 92% of patients in the literature (4968 of 5360 episodes). Risk of PCR-corrected treatment failure was higher for the quinine monotherapy (n=244, adjusted hazard ratio [aHR] 6·11, 95% CI 2·57-14·54, p<0·0001) but lower for artesunate-amodiaquine (n=840, 0·27, 95% 0·14-0·52, p<0·0001), artesunate-mefloquine (n=1028, 0·56, 95% 0·34-0·94, p=0·03), and dihydroartemisinin-piperaquine (n=872, 0·35, 95% CI 0·18-0·68, p=0·002) than artemether-lumefantrine (n=1278) after adjustment for baseline asexual parasitaemia and parity. The risk of gametocyte carriage on day 7 was higher after quinine-based therapy than artemisinin-based treatment (adjusted odds ratio [OR] 7·38, 95% CI 2·29-23·82)., Interpretation: Efficacy and tolerability of artemisinin-based combination therapies (ACTs) in pregnant women are better than quinine. The lower efficacy of artemether-lumefantrine compared with other ACTs might require dose optimisation., Funding: The Bill & Melinda Gates Foundation, ExxonMobil Foundation, and the University of Oxford Clarendon Fund., (Copyright © 2020 The Author(s).

Plasmodium falciparum in pregnancy is a major cause of adverse pregnancy outcomes. We combine performance estimates of standard rapid diagnostic tests (RDT) from trials of intermittent screening and treatment in pregnancy (ISTp) with modelling to assess whether screening at antenatal visits improves upon current intermittent preventative therapy with sulphadoxine-pyrimethamine (IPTp-SP). We estimate that RDTs in primigravidae at first antenatal visit are substantially more sensitive than in non-pregnant adults (OR = 17.2, 95% Cr.I. 13.8-21.6), and that sensitivity declines in subsequent visits and with gravidity, likely driven by declining susceptibility to placental infection. Monthly ISTp with standard RDTs, even with highly effective drugs, is not superior to monthly IPTp-SP. However, a hybrid strategy, recently adopted in Tanzania, combining testing and treatment at first visit with IPTp-SP may offer benefit, especially in areas with high-grade SP resistance. Screening and treatment in the first trimester, when IPTp-SP is contraindicated, could substantially improve pregnancy outcomes.

Background: Sulfadoxine-pyrimethamine (SP) is used as intermittent preventive therapy in pregnancy (IPTp) for malaria in sub-Saharan Africa. The resistance marker dhps A581G has been associated with reduced IPTp-SP efficacy and enhanced morbidity in SP recipients., Methods: We measured SP-resistance allele frequencies in Malawian women participating in a trial comparing IPTp with SP against intermittent screening by rapid diagnostic tests (ISTp). We genotyped polymerase chain reaction-detected parasites using deep sequencing of SP-resistance alleles., Results: Among 125 placental infections, A581G-bearing parasites were associated with reduced birth weight (mean difference [MD], 252 g; 95% confidence interval [CI], 46-457; P = .017). Relative to ISTp, IPTp-SP was associated with higher birth weights in women with wild-type parasites (MD, 116 g; 95% CI, -40 to 272; P = .142) and lower birth weights in women with A581G-bearing parasites (MD, 192 g; 95% CI, -264 to 648; P = .385) (Pinteraction = .033). Similar associations were noted on gestational age (Pinteraction = .075). Amongst only IPTp-SP recipients, relative to women who last received SP > 4 weeks before delivery, recent SP receipt was associated with lower birth weight in women with wild-type parasites (MD, 118 g; 95% CI, -376 to 139; P = .361) and higher birth weight in women with A581G-bearing parasites (MD, 783 g; 95% CI, -20 to 1586; P = .054) (Pinteraction = .005)., Conclusions: The effectiveness in birth weight of IPTp-SP is compromised by A581G-bearing parasites, but there was no evidence that the adverse effects of these parasites are exacerbated by antenatal SP., Isrctn Registry: www.isrctn.com/ISRCTN69800930., (© The Author(s) 2020.

Objective: We investigated the effects of a 12-week exercise intervention on insulin sensitivity (SI) and hyperinsulinemia and associated changes in regional and ectopic fat., Research Design and Methods: Healthy, black South African women with obesity (mean age 23 ± 3.5 years) and of isiXhosa ancestry were randomised into a 12-week aerobic and resistance exercise training group (n = 23) and a no exercise group (control, n = 22). Pre and post-intervention testing included assessment of SI, insulin response to glucose (AIRg), insulin secretion rate (ISR), hepatic insulin extraction (FEL) and disposition index (DI) (AIRg × SI) (frequently sampled i.v. glucose tolerance test); fat mass and regional adiposity (dual-energy X-ray absorptiometry); hepatic, pancreatic and skeletal muscle fat content and abdominal s.c. and visceral adipose tissue volumes (MRI)., Results: Exercise training increased VO2peak (mean ± s.d.: 24.9 ± 2.42 to 27.6 ± 3.39 mL/kg/min, P < 0.001), SI (2.0 (1.2-2.8) to 2.2 (1.5-3.7) (mU/l)-1 min-1, P = 0.005) and DI (median (interquartile range): 6.1 (3.6-7.1) to 6.5 (5.6-9.2) × 103 arbitrary units, P = 0.028), and decreased gynoid fat mass (18.5 ± 1.7 to 18.2 ± 1.6%, P < 0.001) and body weight (84.1 ± 8.7 to 83.3 ± .9.7 kg, P = 0.038). None of these changes were observed in the control group, but body weight increased (P = 0.030). AIRg, ISR and FEL, VAT, SAT and ectopic fat were unaltered after exercise training. The increase in SI and DI were not associated with changes in regional or ectopic fat., Conclusion: Exercise training increased SI independent from changes in hyperinsulinemia and ectopic fat, suggesting that ectopic fat might not be a principal determinant of insulin resistance in this cohort.
