The impact of colistin-based regimens on mortality compared to other antimicrobials in patients with carbapenem-resistant Enterobacterales bacteremia in South African hospitals: a cross-sectional study.

BACKGROUND: Treatment of carbapenem-resistant Enterobacterales (CRE) infections in low-resource settings is challenging particularly due to limited treatment options. Colistin is the mainstay drug for treatment; however, nephrotoxicity and neurotoxicity make this drug less desirable. Thus, mortality may be higher among patients treated with alternative antimicrobials that are potentially less efficacious than colistin. We assessed mortality in patients with CRE bacteremia treated with colistin-based therapy compared to colistin-sparing therapy. METHODS: We conducted a cross-sectional study using secondary data from a South African national laboratory-based CRE bacteremia surveillance system from January 2015 to December 2020. Patients hospitalized at surveillance sentinel sites with CRE isolated from blood cultures were included. Multivariable logistic regression modeling, with multiple imputations to account for missing data, was conducted to determine the association between in-hospital mortality and colistin-based therapy versus colistin-sparing therapy. RESULTS: We included 1 607 case-patients with a median age of 29 years (interquartile range [IQR], 0-52 years) and 53% (857/1 607) male. Klebsiella pneumoniae caused most of the infections (82%, n=1 247), and the most common carbapenemase genes detected were blaOXA-48-like (61%, n=551), and blaNDM (37%, n=333). The overall in-hospital mortality was 31% (504/1 607). Patients treated with colistin-based combination therapy had a lower case fatality ratio (29% [152/521]) compared to those treated with colistin-sparing therapy 32% [352/1 086]) (p=0.18). In our imputed model, compared to colistin-sparing therapy, colistin-based therapy was associated with similar odds of mortality (adjusted odds ratio [aOR] 1.02; 95% confidence interval [CI] 0.78-1.33, p=0.873). CONCLUSION: In our resource-limited setting, the mortality risk in patients treated with colistin-based therapy was comparable to that of patients treated with colistin-sparing therapy. Given the challenges with colistin treatment and the increasing resistance to alternative agents, further investigations into the benefit of newer antimicrobials for managing CRE infections are needed.

A tool to define and measure maternal healthcare acceptability at a selected health sub-district in South Africa.

BACKGROUND: There are many factors during pregnancy and labor that influence women's acceptability of maternal healthcare. Nevertheless, the concept of acceptability of maternal healthcare has unfortunately not been clearly defined and remains difficult to assess, affecting its implications and approaches from maternal health perspectives. In this study, we proposed a practical definition of maternal healthcare acceptability and developed a tool to measure maternal healthcare acceptability from patients' perspective at a selected health sub-district in South Africa. METHODS: We applied known techniques to develop measurement tools in health settings. The concept development drew from the literature review leading to the proposed definition of maternal healthcare acceptability which was then refined and validated by experts through Delphi technique. Other techniques included specification of concept constructs; selection of indicators; formation of indices; measurement tool/scale construction; and testing of reliability and validity. Factor analysis and simple arithmetic equation were performed on secondary and primary datasets respectively. RESULTS: Experts in the field reached a consensual definition of maternal healthcare acceptability. Factor analysis revealed three factors retained to predict maternal healthcare acceptability indices, namely provider, healthcare and community. Structural equation model showed good fit (CFI = 0.97), with good reliability and validity. Hypothesis testing confirmed that items and their corresponding factors were related (p < 0.01). Simple arithmetic equation was recommended as alternative method to measure acceptability when factor analysis was not applicable. CONCLUSION: This study provides new insights into defining and measuring acceptability of maternal healthcare with significant contributions on existing theories and practices on this topic and practical applications not only for maternal health but also across diverse health disciplines.

Bayesian spatial modelling of intimate partner violence and associated factors among adult women and men: evidence from 2019/2020 Rwanda Demographic and Health Survey.

BACKGROUND: Intimate partner violence (IPV) remains a global public health concern for both men and women. Spatial mapping and clustering analysis can reveal subtle patterns in IPV occurrences but are yet to be explored in Rwanda, especially at a lower small-area scale. This study seeks to examine the spatial distribution, patterns, and associated factors of IPV among men and women in Rwanda. METHODS: This was a secondary data analysis of the 2019/2020 Rwanda Demographic and Health Survey (RDHS) individual-level data set for 1947 women aged 15-49 years and 1371 men aged 15-59 years. A spatially structured additive logistic regression model was used to assess risk factors for IPV while adjusting for spatial effects. The district-level spatial model was adjusted for fixed covariate effects and was implemented using a fully Bayesian inference within the generalized additive mixed effects framework. RESULTS: IPV prevalence amongst women was 45.9% (95% Confidence interval (CI): 43.4-48.5%) while that for men was 18.4% (95% CI: 16.2-20.9%). Using a bivariate choropleth, IPV perpetrated against women was higher in the North-Western districts of Rwanda whereas for men it was shown to be more prevalent in the Southern districts. A few districts presented high IPV for both men and women. The spatial structured additive logistic model revealed higher odds for IPV against women mainly in the North-western districts and the spatial effects were dominated by spatially structured effects contributing 64%. Higher odds of IPV were observed for men in the Southern districts of Rwanda and spatial effects were dominated by district heterogeneity accounting for 62%. There were no statistically significant district clusters for IPV in both men or women. Women with partners who consume alcohol, and with controlling partners were at significantly higher odds of IPV while those in rich households and making financial decisions together with partners were at lower odds of experiencing IPV. CONCLUSION: Campaigns against IPV should be strengthened, especially in the North-Western and Southern parts of Rwanda. In addition, the promotion of girl-child education and empowerment of women can potentially reduce IPV against women and girls. Furthermore, couples should be trained on making financial decisions together. In conclusion, the implementation of policies and interventions that discourage alcohol consumption and control behaviour, especially among men, should be rolled out.

Building consensus in defining and conceptualizing acceptability of healthcare: A Delphi study.

BACKGROUND: The concept of healthcare acceptability is important for nursing staff spending most of their time with patients. Nevertheless, acceptability remains confusing without a collective definition in existing literature. OBJECTIVE: This study aimed to create a consensus among experts on definition and conceptual framework of healthcare acceptability. METHODS: We conducted two rounds of Delphi surveys to collect opinions from experts on definition and conceptual framework of healthcare acceptability proposed following thematic content analysis. We calculated the consensus among experts using the modified Appraisal of Guidelines for Research & Evaluation II (AGREE II) instrument and followed the guidance on conducting and reporting Delphi studies (CREDES) best practices. RESULTS: A total of 34 experts completed two rounds of Delphi survey. The definition was validated through consensus as: "a multi-construct concept describing the nonlinear cumulative combination in parts or in whole of experienced or anticipated specific healthcare from the relevant patients/participants, communities, providers/researchers or healthcare systems' managers and policy makers' perspectives in a given context." The overall quality rating was 92.6% and 95.1% for the proposed definition and conceptual framework respectively. CONCLUSION: Opinions collected from experts provided significant insights to build a consensus on healthcare acceptability advancing public health nursing.

Readmission of adolescent psychiatric patients to a specialised unit in Gauteng, South Africa.

Background: Readmission rates to child and adolescent psychiatric units among the youth have been reported to be increasing. Aim: The study aimed to determine the readmission rate and factors associated with readmission of adolescent psychiatric patients at a child and adolescent psychiatric unit. Setting: A specialised psychiatric hospital in Gauteng province, South Africa. Methods: This retrospective cohort study utilised data from the records of patients admitted to the adolescent inpatient unit over a period of five years. The cumulative incidence and incidence rate of readmission within one year of discharge from the index admission was calculated using survival analysis methods. Characteristics significantly associated with readmission were determined by applying the multivariable Cox proportional hazards regression model. Results: Among the 189 patients included in the analysis, the cumulative incidence of readmission within one year of discharge was 17.5%. The incidence rate was 5.31 readmissions per 10 000 person-days. The final multivariable model showed that a diagnosis of schizophrenia (p = 0.015), a diagnosis of attention deficit hyperactivity disorder (p = 0.039), and coming from a child and youth care centre or temporary safe care (p = 0.018) increased the risk of readmission while having a medical condition (p = 0.008) reduced the risk. Conclusion: Psychiatric diagnosis and residential care could be potential risk markers for readmission. Improving the collaboration between health and social services in residential care would be beneficial. Contribution: Identifying factors that predispose adolescent psychiatric patients to readmission can inform and improve management and risk assessments.

Prevalence and factors associated with self-reported HIV testing among adolescent girls and young women in Rwanda: evidence from 2019/20 Rwanda Demographic and Health Survey.

BACKGROUND: HIV/AIDS remains a major public health problem globally. The majority of people living with HIV are from Sub-Saharan Africa, particularly adolescent girls and young women (AGYW) aged 15-24 years. HIV testing is crucial as it is the gateway to HIV prevention, treatment, and care; therefore this study determined the prevalence and factors associated with self-reported HIV testing among AGYW in Rwanda. METHODS: We conducted secondary data analysis on the AGYW using data extracted from the nationally representative population-based 2019/2020 cross-sectional Rwanda Demographic and Health Survey (DHS). We described the characteristics of study participants and determined the prevalence of HIV testing and associated factors using the multivariable logistic regression model. We adjusted all our analyses for unequal sampling probabilities using survey weights. RESULTS: There were a total of 5,732 AGYW, with the majority (57%) aged 15-19 years, 83% were not living with a man, 80% were from rural areas, 29% were from the East region, and 20% had a history of pregnancy. Self-reported HIV testing prevalence was 55.4% (95%CI: 53.7 to 57.0%). The odds of ever having an HIV test were significantly higher for those aged 20-24 years (aOR 2.87, 95%CI: 2.44 to 3.37); with higher education (aOR 2.41, 95%CI:1.48 to 3.93); who were rich (aOR 2.06, 95%CI:1.57 to 2.70); with access to at least one media (aOR 1.64, 95%CI: 1.14 to 2.37); who had ever been pregnant (aOR 16.12, 95%CI: 9.60 to 27.07); who ever had sex (aOR 2.40, 95%CI: 1.96 to 2.95); and those who had comprehensive HIV knowledge (aOR 1.34, 95%CI: 1.17 to 1.54). CONCLUSIONS: We report an unmet need for HIV testing among AGYW in Rwanda. We recommend a combination of strategies to optimize access to HIV testing services, especially among the 15-19 years adolescent girls, including facility-based testing, school and community outreach, awareness campaigns on HIV testing, and home-based testing through HIV self-testing.

Knowledge, attitudes, and perceptions of long-acting reversible contraceptive methods among healthcare workers in sub-Saharan Africa.

OBJECTIVE: To assess the knowledge, attitudes and perceptions (KAP) of long-acting reversible contraceptive (LARC) methods among healthcare workers (HCWs) in sub-Saharan Africa (SSA). METHODS: A systematic review and meta-analysis were conducted following the PRISMA method. Two authors independently searched three electronic databases for studies published between 2000 and January 2020 reporting on the KAP of LARC methods among HCWs in SSA. Titles and abstracts were screened against eligibility criteria, data were extracted and the included studies were assessed for risk of bias. A meta-analysis of proportions for 11 pre-determined questions relating to LARC KAP was performed. Heterogeneity was explored using the I2 -statistic and publication bias investigated using funnel plots and Egger's tests. RESULTS: Twenty-two studies comprising 11,272 HCWs from 11 SSA countries were included. 50% (95% CI: 34%, 67%) of HCWs had received intrauterine contraceptive device (IUCD) insertion training while 63% (95% CI: 44%, 81%) expressed a desire for training. Only 27% (95% CI: 18%, 36%) deemed IUCD appropriate for HIV-infected women. Restrictions for IUCD and injectables based on a minimum age were imposed by 56% (95% CI: 33%, 78%) and 60% (95% CI: 36%, 84%), respectively. Minimum parity restrictions were observed among 29% (95% CI: 9%, 50%) of HCWs for IUCDs and 36% (95% CI: 16%, 56%) for injectable contraceptives. Heterogeneity was high and publication bias was present in two of the 11 questions. CONCLUSION: The systematic review and meta-analysis indicate that unnecessary provider-imposed restrictions may hinder the uptake of LARC methods by women in SSA.

The incidence and mortality of yellow fever in Africa: a systematic review and meta-analysis.

BACKGROUND: Understanding the occurrence of yellow fever epidemics is critical for targeted interventions and control efforts to reduce the burden of disease. We assessed data on the yellow fever incidence and mortality rates in Africa. METHODS: We searched the Cochrane Library, SCOPUS, MEDLINE, CINAHL, PubMed, Embase, Africa-wide and Web of science databases from 1 January 1975 to 30th October 2020. Two authors extracted data from included studies independently and conducted a meta-analysis. RESULTS: Of 840 studies identified, 12 studies were deemed eligible for inclusion. The incidence of yellow fever per 100,000 population ranged from < 1 case in Nigeria, < 3 cases in Uganda, 13 cases in Democratic Republic of the Congo, 27 cases in Kenya, 40 cases in Ethiopia, 46 cases in Gambia, 1267 cases in Senegal, and 10,350 cases in Ghana. Case fatality rate associated with yellow fever outbreaks ranged from 10% in Ghana to 86% in Nigeria. The mortality rate ranged from 0.1/100,000 in Nigeria to 2200/100,000 in Ghana. CONCLUSION: The yellow fever incidence rate is quite constant; in contrast, the fatality rates vary widely across African countries over the study period. Standardized demographic health surveys and surveillance as well as accurate diagnostic measures are essential for early recognition, treatment and control.

Trends in RPR Seropositivity among Children Younger than 2 Years in South Africa, 2010-2019.

A positive rapid plasma reagin (RPR) result in children under the age of 2 years indicates either passive transplacental transfer of maternal antibodies or active infection with syphilis (possible congenital syphilis). We describe trends in RPR seropositivity in this population using centralized laboratory data. A secondary analysis of laboratory data collected through the National Health Laboratory Service, Corporate Data Warehouse from 2010 to 2019 was conducted. Of the 127 150 children <2 years included in the analysis, 10 969 [8.6%; 95% confidence interval (95% CI) 85-88]) were RPR seropositive. RPR seropositivity increased from 6.5% to 13.0% between 2010 and 2019. Overall, the annual rate of RPR seropositivity was relatively stable between 2010 and 2018 with a range of 89-127/100 000 live births, increasing sharply to 165/100 000 livebirths in 2019. KwaZulu-Natal and North West provinces recorded the largest increases in annual seropositivity rate, while Eastern Cape and Western Cape had the most significant declines. Although this analysis is limited to laboratory results, in the absence of major changes in testing practices, there may be a rise in the burden of antenatal syphilis exposure in utero indicating an increase in maternal syphilis and syphilis transmission in the general population. South Africa needs to intensify Mother-to-Child Transmission of syphilis elimination efforts to reach the WHO target of ≤50 cases per 100 live births by 2030.

Effectiveness of vaginal microbicides in preventing HIV transmission.

OBJECTIVE: To evaluate the evidence on the effectiveness of vaginal microbicides in preventing HIV transmission in women. METHODS: Systematic review through a comprehensive search of relevant electronic databases for eligible randomised controlled trials (RCTs) published through June 2019. Two authors independently screened titles and abstracts according to eligibility criteria, then extracted data and assessed risk of bias of included studies. We conducted a random-effects meta-analysis of risk ratios (RR) of HIV infection and assessed heterogeneity using chi-squared and I2 tests. Sources of heterogeneity were investigated through subgroup analysis, publication bias was assessed using funnel plots, and certainty of evidence was graded using GRADEPro software. RESULTS: We included 18 RCTs which enrolled 40,048 sexually active, HIV-negative, non-pregnant women, aged 16 years and older, mainly from sub-Saharan Africa. The intravaginal ring containing dapivirine significantly reduced HIV risk by 29% (RR 0.71, 95% CI: 0.57-0.89; 2 RCTs, 4,564 women, moderate certainty of evidence). Estimates of effect of tenofovir 1% (RR 0.83, 95% CI: 0.65-1.06), nonoxynol-9 (RR 1.15, 95% CI: 0.93-1.42), cellulose sulphate (RR 1.16, 95% CI: 0.61-2.21), SAVVY (RR 1.34, 95% CI: 0.69-2.59), Carraguard (RR 0.89, 95% CI: 0.71-1.10), BufferGel (RR 1.02, 95% CI: 0.71-1.46), 0.5% PRO2000 (RR 0.88, 95% CI: 0.60-1.28) and 2% PRO2000 (RR 0.81, 95% CI: 0.58-1.12) failed to reach statistical significance; each had low certainty of evidence. CONCLUSION: The long-acting intravaginal ring containing dapivirine significantly reduced risk of HIV transmission in women by 29%. The remaining microbicides had no evident effect.

OBJECTIF: Evaluer les données probantes sur l'efficacité des microbicides vaginaux dans la prévention de la transmission du VIH chez les femmes. MÉTHODES: Analyse systématique à travers une recherche exhaustive des bases de données électroniques pertinentes pour les essais contrôlés randomisés (ECR) éligibles publiés jusqu'en juin 2019. Deux auteurs ont indépendamment passé en revue les titres et résumés selon des critères d'éligibilité, les données ont alors été extraites et le risque de biais évalué pour des études incluses. Nous avons effectué une méta-analyse des effets aléatoires des rapports de risque (RR) de l'infection par le VIH et évalué l'hétérogénéité à l'aide des tests Chi2 et I2 . Les sources d'hétérogénéité ont été étudiées par analyse de sous-groupes, le biais de publication a été évalué à l'aide de graphiques en entonnoir et la certitude des données a été évaluée à l'aide du logiciel GRADEPro. RÉSULTATS: Nous avons inclus 18 ECR qui ont recruté 40.048 femmes sexuellement actives, négatives pour le VIH, non enceintes, âgées de 16 ans et plus, principalement d'Afrique subsaharienne. L'anneau intravaginal contenant de la dapivirine a significativement réduit le risque de VIH de 29% (RR: 0,71 ; IC95%: 0,57-0,89; 2 ECR, 4564 femmes, certitude modérée des preuves). Les estimations de l'effet du ténofovir 1% (RR: 0,83 ; IC95%: 0,65-1,06), du nonoxynol-9 (RR: 1,15 ; IC95%: 0,93-1,42), du sulfate de cellulose (RR: 1,16 ; IC 95%: 0,61-2,21 ), du SAVVY (RR: 1,34 ; IC95%: 0,69-2,59), du Carraguard (RR: 0,89, IC95%: 0,71-1,10), du BufferGel (RR: 1,02 ; IC95%: 0,71-1,46), du PRO2000 à 0,5% (RR: 0,88 ; IC95%: 0,60-1,28) et du PRO2000 à 2% (RR: 0,81 ; IC95%: 0,58-1,12) n'ont pas atteint la signification statistique; tous avaient une faible certitude d'évidence. CONCLUSION: L'anneau intravaginal à longue durée d'action contenant de la dapivirine a réduit de manière significative le risque de transmission du VIH chez les femmes de 29%. Les autres microbicides n'ont eu aucun effet évident.

Interventions for preventing postpartum constipation.

BACKGROUND: Postpartum constipation, with symptoms, such as pain or discomfort, straining, and hard stool, is a common condition affecting mothers. Haemorrhoids, pain at the episiotomy site, effects of pregnancy hormones, and haematinics used in pregnancy can increase the risk of postpartum constipation. Eating a high-fibre diet and increasing fluid intake are usually encouraged. Although laxatives are commonly used in relieving constipation, the effectiveness and safety of available interventions for preventing postpartum constipation should be ascertained. This is an update of a review first published in 2015. OBJECTIVES: To evaluate the effectiveness and safety of interventions for preventing postpartum constipation. SEARCH METHODS: We searched Cochrane Pregnancy and Childbirth's Trials Register, and two trials registers ClinicalTrials.gov, the WHO International Clinical Trials Registry Platform (ICTRP) (7 October 2019), and screened reference lists of retrieved trials. SELECTION CRITERIA: We considered all randomised controlled trials (RCTs) comparing any intervention for preventing postpartum constipation versus another intervention, placebo, or no intervention in postpartum women. Interventions could include pharmacological (e.g. laxatives) and non-pharmacological interventions (e.g. acupuncture, educational and behavioural interventions). Quasi-randomised trials and cluster-RCTs were eligible for inclusion; none were identified. Trials using a cross-over design were not eligible. DATA COLLECTION AND ANALYSIS: Two review authors independently screened the results of the search to select potentially relevant trials, extracted data, assessed risk of bias, and the certainty of the evidence, using the GRADE approach. We did not pool results in a meta-analysis, but reported them per study. MAIN RESULTS: We included five trials (1208 postpartum mothers); three RCTs and two quasi-RCTs. Four trials compared a laxative with placebo; one compared a laxative plus a bulking agent versus the same laxative alone, in women who underwent surgical repair of third degree perineal tears. Trials were poorly reported, and four of the five trials were published over 40 years ago. We judged the risk of bias to be unclear for most domains. Overall, we found a high risk of selection and attrition bias. Laxative versus placebo We included four trials in this comparison. Two of the trials examined the effects of laxatives that are no longer used; one has been found to have carcinogenic properties (Danthron), and the other is not recommended for lactating women (Bisoxatin acetate); therefore, we did not include their results in our main findings. None of the trials included in this comparison assessed our primary outcomes: pain or straining on defecation, incidence of postpartum constipation, or quality of life; or many of our secondary outcomes. A laxative (senna) may increase the number of women having their first bowel movement within 24 hours after delivery (risk ratio (RR) 2.90, 95% confidence interval (CI) 2.24 to 3.75; 1 trial, 471 women; low-certainty evidence); may have little or no effect on the number of women having their first bowel movement on day one after delivery (RR 0.94, 95% CI 0.72 to 1.22; 1 trial, 471 women; very low-certainty evidence); may reduce the number of women having their first bowel movement on day two (RR 0.23, 95% CI 0.11 to 0.45; 1 trial, 471 women; low-certainty evidence); and day three (RR 0.05, 95% CI 0.00 to 0.89; 1 trial, 471 women; low-certainty evidence); and may have little or no effect on the number of women having their first bowel movement on day four after delivery (RR 0.22, 95% CI 0.03 to 1.87; 1 trial, 471 women; very low-certainty evidence), but some of the evidence is very uncertain. Adverse effects were poorly reported. Low-certainty evidence suggests that the laxative (senna) may increase the number of women experiencing abdominal cramps (RR 4.23, 95% CI 1.75 to 10.19; 1 trial, 471 women). Very low-certainty evidence suggests that laxatives taken by the mother may have little or no effect on loose stools in the baby (RR 0.62, 95% CI 0.16 to 2.41; 1 trial, 281 babies); or diarrhoea (RR 2.46, 95% CI 0.23 to 26.82; 1 trial, 281 babies). Laxative plus bulking agent versus laxative only Very low-certainty evidence from one trial (147 women) suggests no evidence of a difference between these two groups of women who underwent surgical repair of third degree perineal tears; only median and range data were reported. The trial also reported no evidence of a difference in the incidence of postpartum constipation (data not reported), but did not report on quality of life. Time to first bowel movement was reported as a median (range); very low-certainty evidence suggests little or no difference between the two groups. A laxative plus bulking agent may increase the number of women having any episode of faecal incontinence during the first 10 days postpartum (RR 1.81, 95% CI 1.01 to 3.23; 1 trial, 147 women; very low-certainty evidence). The trial did not report on adverse effects of the intervention on babies, or many of our secondary outcomes. AUTHORS' CONCLUSIONS: There is insufficient evidence to make general conclusions about the effectiveness and safety of laxatives for preventing postpartum constipation. The evidence in this review was assessed as low to very low-certainty evidence, with downgrading decisions based on limitations in study design, indirectness and imprecision. We did not identify any trials assessing educational or behavioural interventions. We identified four trials that examined laxatives versus placebo, and one that examined laxatives versus laxatives plus stool bulking agents. Further, rigorous trials are needed to assess the effectiveness and safety of laxatives during the postpartum period for preventing constipation. Trials should assess educational and behavioural interventions, and positions that enhance defecation. They should report on the primary outcomes from this review: pain or straining on defecation, incidence of postpartum constipation, quality of life, time to first bowel movement after delivery, and adverse effects caused by the intervention, such as: nausea or vomiting, pain, and flatus.

Ready-to-use therapeutic food (RUTF) for home-based nutritional rehabilitation of severe acute malnutrition in children from six months to five years of age.

BACKGROUND: Management of severe acute malnutrition (SAM) in children comprises two potential phases: stabilisation and rehabilitation. During the initial stabilisation phase, children receive treatment for dehydration, electrolyte imbalances, intercurrent infections and other complications. In the rehabilitation phase (applicable to children presenting with uncomplicated SAM or those with complicated SAM after complications have been resolved), catch-up growth is the main focus and the recommended energy and protein requirements are much higher. In-hospital rehabilitation of children with SAM is not always desirable or practical - especially in rural settings - and home-based care can offer a better solution. Ready-to-use therapeutic food (RUTF) is a widely used option for home-based rehabilitation, but the findings of our previous review were inconclusive. OBJECTIVES: To assess the effects of home-based RUTF used during the rehabilitation phase of SAM in children aged between six months and five years on recovery, relapse, mortality and rate of weight gain. SEARCH METHODS: We searched the following databases in October 2018: CENTRAL, MEDLINE, Embase, six other databases and three trials registers. We ran separate searches for cost-effectiveness studies, contacted researchers and healthcare professionals in the field, and checked bibliographies of included studies and relevant reviews. SELECTION CRITERIA: Randomised controlled trials (RCTs) and quasi-RCTs, where children aged between six months and five years with SAM were, during the rehabilitation phase, treated at home with RUTF compared to an alternative dietary approach, or with different regimens and formulations of RUTF compared to each other. We assessed recovery, deterioration or relapse and mortality as primary outcomes; and rate of weight gain, time to recovery, anthropometrical changes, cognitive development and function, adverse outcomes and acceptability as secondary outcomes. DATA COLLECTION AND ANALYSIS: We screened for eligible studies, extracted data and assessed risk of bias of those included, independently and in duplicate. Where data allowed, we performed a random-effects meta-analysis using Review Manager 5, and investigated substantial heterogeneity through subgroup and sensitivity analyses. For the main outcomes, we evaluated the quality of the evidence using GRADE, and presented results in a 'Summary of findings' table per comparison. MAIN RESULTS: We included 15 eligible studies (n = 7976; effective sample size = 6630), four of which were cluster trials. Eight studies were conducted in Malawi, four in India, and one apiece in Kenya, Zambia, and Cambodia. Six studies received funding or donations from industry whereas eight did not, and one study did not report the funding source.The overall risk of bias was high for six studies, unclear for three studies, and low for six studies. Among the 14 studies that contributed to meta-analyses, none (n = 5), some (n = 5) or all (n = 4) children were stabilised in hospital prior to commencement of the study. One small study included only children known to be HIV-infected, another study stratified the analysis for 'recovery' according to HIV status, while the remaining studies included HIV-uninfected or untested children. Across all studies, the intervention lasted between 8 and 16 weeks. Only five studies followed up children postintervention (maximum of six months), and generally reported on a limited number of outcomes.We found seven studies with 2261 children comparing home-based RUTF meeting the World Health Organization (WHO) recommendations for nutritional composition (referred to in this review as standard RUTF) with an alternative dietary approach (effective sample size = 1964). RUTF probably improves recovery (risk ratio (RR) 1.33; 95% confidence interval (CI) 1.16 to 1.54; 6 studies, 1852 children; moderate-quality evidence), and may increase the rate of weight gain slightly (mean difference (MD) 1.12 g/kg/day, 95% CI 0.27 to 1.96; 4 studies, 1450 children; low-quality evidence), but we do not know the effects on relapse (RR 0.55, 95% CI 0.30 to 1.01; 4 studies, 1505 children; very low-quality evidence) and mortality (RR 1.05, 95% CI 0.51 to 2.16; 4 studies, 1505 children; very low-quality evidence).Two quasi-randomised cluster trials compared standard, home-based RUTF meeting total daily nutritional requirements with a similar RUTF but given as a supplement to the usual diet (213 children; effective sample size = 210). Meta-analysis showed that standard RUTF meeting total daily nutritional requirements may improve recovery (RR 1.41, 95% CI 1.19 to 1.68; low-quality evidence) and reduce relapse (RR 0.11, 95% CI 0.01 to 0.85; low-quality evidence), but the effects are unknown for mortality (RR 1.36, 95% CI 0.46 to 4.04; very low-quality evidence) and rate of weight gain (MD 1.21 g/kg/day, 95% CI - 0.74 to 3.16; very low-quality evidence).Eight studies randomised 5502 children (effective sample size = 4456) and compared standard home-based RUTF with RUTFs of alternative formulations (e.g. using locally available ingredients, containing less or no milk powder, containing specific fatty acids, or with added pre- and probiotics). For recovery, it made little or no difference whether standard or alternative formulation RUTF was used (RR 1.03, 95% CI 0.99 to 1.08; 6 studies, 4188 children; high-quality evidence). Standard RUTF decreases relapse (RR 0.84, 95% CI 0.72 to 0.98; 6 studies, 4188 children; high-quality evidence). However, it probably makes little or no difference to mortality (RR 1.00, 95% CI 0.80 to 1.24; 7 studies, 4309 children; moderate-quality evidence) and may make little or no difference to the rate of weight gain (MD 0.11 g/kg/day, 95% CI -0.32 to 0.54; 6 studies, 3807 children; low-quality evidence) whether standard or alternative formulation RUTF is used. AUTHORS' CONCLUSIONS: Compared to alternative dietary approaches, standard RUTF probably improves recovery and may increase rate of weight gain slightly, but the effects on relapse and mortality are unknown. Standard RUTF meeting total daily nutritional requirements may improve recovery and relapse compared to a similar RUTF given as a supplement to the usual diet, but the effects on mortality and rate of weight gain are not clear. When comparing RUTFs with different formulations, the current evidence does not favour a particular formulation, except for relapse, which is reduced with standard RUTF. Well-designed, adequately powered, pragmatic RCTs with standardised outcome measures, stratified by HIV status, and that include diarrhoea as an outcome, are needed.

Predictors of male condom use among sexually active heterosexual young women in South Africa, 2012.

BACKGROUND: In South Africa, young women are at disproportionate risk of HIV infection with about 2363 new infections per week in 2015. Proper condom use is one of the most effective HIV/AIDS prevention strategies among sexually active persons. Understanding factors associated with male condom use in this key population group is important to curb the spread of HIV. This study determined practices and predictors of male condom use among sexually active young women in South Africa. METHODS: The 2012 National HIV Communication Survey measured the extent of exposure to communication activities for HIV prevention among men and women aged 16-55 years in South Africa. We performed a secondary data analysis on a subset of this survey, focussing on 1031 women aged 16-24 years who reported having had sex in the past 12 months. We determined predictors of male condom use using the unconditional multivariable logistic regression model. RESULTS: Of the 1031 young women, 595 (57.8%) reported using a male condom at last sex, 68.4% in women aged 16-19 years and 54.5% in women aged 20-24 years (p < 0.001). Delayed sexual debut [20 years or above] (Adjusted Odds Ratio [aOR] 2.1, 95% CI: 1.2 to 3.7, p = 0.006); being a student (aOR 1.6, 95% CI: 1.2 to 2.3, p = 0.005); and exposure to HIV communication programmes (aOR 3.1, 95% CI: 1.2 to 8.6, p = 0.025) were significantly associated with male condom use at last sex. CONCLUSION: Male condom use was a common practice among young women and was associated with delayed sexual debut and exposure to HIV communication programmes. Behavioral interventions and HIV communication programmes should therefore encourage young women to delay initiation of sex and promote usage of male condoms.

Access to HIV care and treatment for migrants between Lesotho and South Africa: a mixed methods study.

BACKGROUND: HIV treatment and care for migrants is affected by their mobility and interaction with HIV treatment programs and health care systems in different countries. To assess healthcare needs, preferences and accessibility barriers of HIV-infected migrant populations in high HIV burden, borderland districts of Lesotho. METHODS: We selected 15 health facilities accessed by high patient volumes in three districts of Maseru, Leribe and Mafeteng. We used a mixed methods approach by administering a survey questionnaire to consenting HIV infected individuals on anti-retroviral therapy (ART) and utilizing a purposive sampling procedure to recruit health care providers for qualitative in-depth interviews across facilities. RESULTS: Out of 524 HIV-infected migrants enrolled in the study, 315 (60.1%) were from urban and 209 (39.9%) from rural sites. Of these, 344 (65.6%) were women, 375 (71.6%) were aged between 26 and 45 years and 240 (45.8%) were domestic workers. A total of 486 (92.7%) preferred to collect their medications primarily in Lesotho compared to South Africa. From 506 who responded to the question on preferred dispensing intervals, 63.1% (n = 319) preferred 5-6 month ARV refills, 30.2% (n = 153) chose 3-4 month refills and only 6.7% (n = 34) opted for the standard-of-care 1-2 month refills. A total of 126 (24.4%) defaulted on their treatment and the primary reason for defaulting was failure to get to Lesotho to collect medication (59.5%, 75/126). Treatment default rates were higher in urban than rural areas (28.3% versus 18.4%, p = 0.011). Service providers indicated a lack of transfer letters as the major drawback in facilitating care and treatment for migrants, followed by discrimination based on nationality or language. Service providers indicated that most patients preferred all treatment services to be rendered in Lesotho, as they perceive the treatment provided in South Africa to be different often less strong or with more serious side effects. CONCLUSION: Existing healthcare systems in both South Africa and Lesotho experience challenges in providing proper care and treatment for HIV infected migrants. A need for a differentiated model of ART delivery to HIV infected migrants that allows for multi-month scripting and dispensing is warranted.

Knowledge, attitudes and practices on malaria transmission in Mamfene, KwaZulu-Natal Province, South Africa 2015.

BACKGROUND: In South Africa malaria is endemic in Mpumalanga, Limpopo and the north-eastern areas of KwaZulu-Natal provinces. South Africa has set targets to eliminate malaria by 2018 and research into complementary vector control tools such as the Sterile Insect Technique (SIT) is ongoing. It is important to understand community perceptions regarding malaria transmission and control interventions to enable development of community awareness campaign messages appropriate to the needs of the community. We aimed to assess knowledge, attitudes, and practices regarding malaria transmission to inform a public awareness campaign for SIT in Jozini Local Municipality, Mamfene in KwaZulu-Natal province. METHODS: We conducted a cross-sectional survey in three communities in Mamfene, KwaZulu-Natal during 2015. A structured field piloted questionnaire was administered to 400 randomly selected heads of households. Descriptive statistics were used to summarize data. RESULTS: Of the 400 participants interviewed, 99% had heard about malaria and correctly associated it with mosquito bites. The sources of malaria information were the local health facility (53%), radio (16%) and community meetings (7%). Approximately 63% of the participants were able to identify three or four symptoms of malaria. The majority (76%) were confident that indoor residual spraying (IRS) kills mosquitoes and prevents infection. Bed nets were used by 2% of the participants. SIT knowledge was poor (9%), however 63% of the participants were supportive of mosquito releases for research purposes. The remaining 37% raised concerns and fears, including fear of the unknown and lack of information on the SIT. CONCLUSION: Appropriate knowledge, positive attitude and acceptable treatment-seeking behaviour for malaria were demonstrated by members of the community. Community involvement will be crucial in achieving success of the SIT and future studies should further investigate concerns raised by the community. The existing communication channels used by the malaria control program can be used; however additional channels should be investigated.

Perinatal HIV-1 transmission: Fc gamma receptor variability associates with maternal infectiousness and infant susceptibility.

BACKGROUND: Accumulating data suggest that immune effector functions mediated through the Fc portion of HIV-1-specific immunoglobulin G (IgG) are a key component of HIV-1 protective immunity, affecting both disease progression and HIV-1 acquisition. Through studying Fc gamma receptor (FcγR) variants known to alter IgG Fc-mediated immune responses, we indirectly assessed the role of FcγR-mediated effector functions in modulating perinatal HIV-1 transmission risk. In this study, genotypic data from 79 HIV-1 infected mothers and 78 HIV-1 infected infants (transmitting cases) were compared to 234 HIV-1 infected mothers and 235 HIV-1 exposed-uninfected infants (non-transmitting controls). Associations, unadjusted and adjusted for multiple comparisons, were assessed for overall transmission and according to mode of transmission-intrapartum (n = 31), in utero (n = 20), in utero-enriched (n = 48). RESULTS: The maternal FcγRIIIa-158V allele that confers enhanced antibody binding affinity and antibody-dependent cellular cytotoxicity capacity significantly associated with reduced HIV-1 transmission [odds ratio (OR) 0.47, 95 % confidence interval (CI) 0.28-0.79, P = 0.004; PBonf > 0.05]. In particular, the FcγRIIIa-158V allele was underrepresented in the in utero transmitting group (P = 0.048; PBonf > 0.05) and in utero-enriched transmitting groups (P = 0.0001; PBonf < 0.01). In both mother and infant, possession of an FcγRIIIb-HNA1b allotype that reduces neutrophil-mediated effector functions associated with increased transmission (OR 1.87, 95 % CI 1.08-3.21, P = 0.025; PBonf > 0.05) and acquisition (OR 1.91, 95 % CI 1.11-3.30, P = 0.020; PBonf > 0.05), respectively. Conversely, the infant FcγRIIIb-HNA1a|1a genotype was significantly protective of perinatal HIV-1 acquisition (OR 0.42, 95 % CI 0.18-0.96, P = 0.040; PBonf > 0.05). CONCLUSIONS: The findings of this study suggest a potential role for FcγR-mediated effector functions in perinatal HIV-1 transmission. However, future studies are required to validate the findings of this study, in particular associations that did not retain significance after adjustment for multiple comparisons.

Clinical and Microbiological Features of Salmonella Meningitis in a South African Population, 2003-2013.

BACKGROUND: The clinical and microbiological characteristics of nontyphoidal Salmonella (NTS) meningitis in South Africa, where human immunodeficiency virus (HIV) prevalence is high (approximately 15% in persons ≥15 years of age), were reviewed. METHODS: From 2003 through 2013, 278 cases were identified through national laboratory-based surveillance. Clinical information (age, sex, outcome, Glasgow Coma Scale [GCS], and HIV status) was ascertained at selected sites. Isolates were serotyped; susceptibility testing and multilocus sequence typing on Salmonella enterica serovar Typhimurium isolates was performed. Multivariable logistic regression was used to determine factors associated with mortality outcome, using Stata software, version 13. RESULTS: Where age was ascertained, 139 of 256 (54.3%) patients were <15 years. Males represented 151 of 267 (56.6%). Mortality outcome was recorded for 112 of 146 (76.7%) enhanced surveillance patients; 53 of 112 (47.3%) died. Death was associated with GCS ≤13 (adjusted odds ratio [OR], 18.7; 95% confidence interval [CI], 3.0-118.5; P = .002) on multivariable analysis. Where data were available, all 45 patients aged >15 years were HIV infected, compared with 24 of 46 (52.2%) patients aged <5 years. Neonates were less likely to be HIV infected than infants aged 2-12 months (OR, 4.8; 95% CI, 1.1-21.1; P = .039).Salmonella Typhimurium represented 106 of 238 (44.5%) serotyped isolates: 65 of 95 (68.4%) were ST313 vs ST19, respectively, and significantly associated with HIV-infected patients (P = .03) and multidrug resistance (OR, 6.6; 95% CI, 2.5-17.2; P < .001). CONCLUSIONS: NTS meningitis in South Africa is highly associated with HIV in adults, with neonates (irrespective of HIV status), and with Salmonella Typhimurium ST313. GCS is the best predictor of mortality: early diagnosis and treatment are critical. Focused prevention requires further studies to understand the sources and transmission routes.

Interventions for preventing postpartum constipation.

BACKGROUND: Postpartum constipation, with symptoms such as pain or discomfort, straining, and hard stool, is a common condition affecting mothers. Haemorrhoids, pain at the episiotomy site, effects of pregnancy hormones and haematinics used in pregnancy can increase the risk of postpartum constipation. Eating a high-fibre diet and increasing fluid intake is usually encouraged, although laxatives are commonly used in relieving constipation. The effectiveness and safety of available interventions for preventing postpartum constipation needs to be ascertained. OBJECTIVES: To evaluate the effectiveness and safety of interventions for preventing postpartum constipation. SEARCH METHODS: We searched the Cochrane Pregnancy and Childbirth Group's Trials Register (30 April 2015), Stellenbosch University database, ProQuest Dissertation and Theses database, World Health Organization International Clinical Trials Registry Platform (ICTRP), ClinicalTrials.gov (30 April 2015) and reference lists of included studies. SELECTION CRITERIA: All randomised controlled trials (RCTs) comparing any intervention for preventing postpartum constipation versus another intervention, placebo or no intervention. Interventions could include pharmacological (e.g. laxatives) and non-pharmacological interventions (e.g. acupuncture, educational and behavioural interventions).We included quasi-randomised trials. Cluster-RCTs were eligible for inclusion but none were identified. Studies using a cross-over design were not eligible for inclusion in this review. DATA COLLECTION AND ANALYSIS: Two review authors independently screened the results of the search to select potentially relevant studies, extracted data and assessed risk of bias. Results were pooled in a meta-analysis only where there was no substantial statistical heterogeneity. MAIN RESULTS: We included five trials (1208 postpartum mothers); four compared a laxative with placebo and one compared a laxative alone versus the same laxative plus a bulking agent in women who underwent surgical repair of third degree perineal tears. Trials were poorly reported and risk of bias was unclear for most domains. Overall, there was a high risk of selection and attrition bias. Laxative versus placeboNone of the four trials included in this comparison assessed any of our pre-specified primary outcomes (pain or straining on defecation, incidence of postpartum constipation or changes in quality of life).All four trials reported time to first bowel movement (not pre-specified in our protocol). In one trial, more women in the laxative group had their first bowel movement less than 24 hours after delivery compared to women in the placebo group (risk ratio (RR) 2.90, 95% confidence interval (CI) 2.24 to 3.75, 471 women). Individual trials also reported inconsistent results for days one, two and three after delivery. Pooled results of two trials showed that fewer women in the laxative group were having their first bowel movement at day four compared with controls (average RR 0.36, 95% CI 0.21 to 0.61, 671 women).Regarding secondary outcomes, no trials reported on stool consistency using the Bristol stool form scale orrelief of abdominal pain/discomfort . One trial reported the number of women having loose or watery stools and there were more women who experienced this in the laxative group compared to the placebo group (RR 26.96, 95% CI 3.81 to 191.03, 106 women). One trial found no clear difference in the number of enemas between groups (RR 0.63, 95% CI 0.38 to 1.05, 244 women). One trial reported more women having more than two bowel movements per day in the laxative compared to the placebo group (RR 26.02, 95% CI 1.59 to 426.73, 106 women). Adverse effects were poorly reported; two trials reported the number of women having abdominal cramps, but their results could not be pooled in a meta-analysis due to substantial statistical heterogeneity. In one trial, more women in the laxative group had abdominal cramps compared to the placebo group (RR 4.23, 95% CI 1.75 to 10.19, 471 women), while the other trial showed no difference between groups (RR 0.25, 95% CI 0.03 to 2.20, 200 women). With regards to adverse effects of the intervention on the baby , one trial found no difference in the incidence of loose stools (RR 0.62, 95% CI 0.16 to 2.41, 281 women) or diarrhoea (RR 2.46, 95% CI 0.23 to 26.82, 281 women) between the two groups. Laxative versus laxative plus bulking agentOnly one trial was included in this comparison and reported on pain or straining on defecation in women who underwent surgical repair of third degree perineal tears; there was no reported difference between groups (median (range) data only). No difference was reported in the incidence of postpartum constipation (data not reported) and the outcome changes in quality of life was not mentioned.Time to first bowel movement was reported as a median (range) with no difference between the two groups. In terms of adverse effects , women in the laxative plus stool-bulking group were reported to be at a greater risk of faecal incontinence during the immediate postpartum period (median (range) data only). However the number of women having any episode of faecal incontinence during first 10 days postpartum was reported with no clear difference between the two groups (14/77 (18.2%) versus 23/70 (32.9%), RR 0.55, 95% CI 0.31 to 0.99, 147 women). The trial did not report on adverse effects of the intervention on the babies.The trial reported none of the following pre-specified secondary outcomes: stool consistency using Bristol stool form scale , use of alternative products , laxative agents , enemas , relief of abdominal pain/discomfort and stool frequency . AUTHORS' CONCLUSIONS: We did not identify any trials assessing educational or behavioural interventions. We identified four trials that examined laxatives versus placebo and one that examined laxatives versus laxatives plus stool bulking agents. Results from trials were inconsistent and there is insufficient evidence to make general conclusions about the effectiveness and safety of laxatives.Further rigorous trials are needed to assess the effectiveness and safety of laxatives during the postpartum period for preventing constipation. Trials assessing educational and behavioural interventions and positions that enhance defecation are also needed. Future trials should report on the following important outcomes: pain or straining on defecation; incidence of postpartum constipation, quality of life, time to first bowel movement after delivery, and adverse effects caused by the intervention such as: nausea or vomiting, pain and flatus.

A systematic review and meta-analysis of the effect and safety of ginger in the treatment of pregnancy-associated nausea and vomiting.

BACKGROUND AND OBJECTIVES: Nausea and vomiting during pregnancy (NVP) occur commonly. Possible harmful side-effects of conventional medicine to the fetus create the need for alternative options to relieve NVP. This systematic review (SR) investigated current evidence regarding orally administered ginger for the treatment of NVP. The primary objective was to assess the effectiveness of ginger in treating NVP. The secondary objective was to assess the safety of ginger during pregnancy. METHODS: A comprehensive electronic bibliographic database search was carried out. Randomized controlled trials (RCTs) of the efficacy of orally administered ginger, as treatment for NVP in pregnant women at any stage of pregnancy, published in English, were included. Two researchers independently extracted data and assessed trial quality. RevMan5 software (Cochrane Collaboration) was used for data analysis. p < 0.05 was considered statistically significant. RESULTS: Twelve RCTs involving 1278 pregnant women were included. Ginger significantly improved the symptoms of nausea when compared to placebo (MD 1.20, 95% CI 0.56-1.84, p = 0.0002, I² = 0%). Ginger did not significantly reduce the number of vomiting episodes during NVP, when compared to placebo, although there was a trend towards improvement (MD 0.72, 95% CI -0.03-1.46, p = 0.06, I² = 71%). Subgroup analyses seemed to favor the lower daily dosage of <1500 mg ginger for nausea relief. Ginger did not pose a significant risk for spontaneous abortion compared to placebo (RR 3.14, 95% CI 0.65-15.11, p = 0.15; I² = 0%), or to vitamin B6 (RR 0.49, 95% CI 0.17-1.42, p = 0.19, I² = 40%). Similarly, ginger did not pose a significant risk for the side-effects of heartburn or drowsiness. CONCLUSIONS: This review suggests potential benefits of ginger in reducing nausea symptoms in pregnancy (bearing in mind the limited number of studies, variable outcome reporting and low quality of evidence). Ginger did not significantly affect vomiting episodes, nor pose a risk for side-effects or adverse events during pregnancy. Based on evidence from this SR, ginger could be considered a harmless and possibly effective alternative option for women suffering from NVP.

Interventions for treating postpartum constipation.

BACKGROUND: Constipation is a functional bowel disorder that can reduce quality of life in the puerperium period. The diagnosis of postpartum constipation is both subjective and objective. It is characterised by symptoms such as pain or discomfort, straining, hard lumpy stools and a sense of incomplete bowel evacuation. Haemorrhoids, pain at the episiotomy site, effects of pregnancy hormones and hematinics used in pregnancy can increase the risk of postpartum constipation. Although a high fibre diet and increased fluid intake is encouraged to assist defecation in the puerperium, pain-relieving drugs and laxatives are common drugs of choice to alleviate constipation. However, the effectiveness and safety of laxatives on the nursing mother need to be ascertained. OBJECTIVES: To evaluate the effectiveness of interventions for treating postpartum constipation. SEARCH METHODS: We searched the Cochrane Pregnancy and Childbirth Group's Trials Register (28 March 2014), the metaRegister of Controlled Trials, the US National Institutes of Health Ongoing Trials Register (ClinicalTrials.gov), the Australian New Zealand Clinical Trials Registry (ANZCTR), the World Health Organization International Clinical Trials Registry platform (ICTRP), the ProQuest database, Stellenbosch University database and Google Scholar (28 March 2014). We also searched the reference lists of potentially relevant studies identified by the search, reviewed articles for relevant trials and contacted experts to identify any additional published or unpublished trials (10 April 2014). SELECTION CRITERIA: All randomised controlled trials comparing any intervention for the treatment of postpartum constipation to another intervention, placebo or no intervention.Interventions could include laxatives, surgery, as well as educational and behavioural interventions. DATA COLLECTION AND ANALYSIS: Two review authors independently screened the results of the search to select potentially relevant studies using pre-designed eligibility inclusion criteria. Discrepancies were resolved through discussion. We did not identify any studies for inclusion. MAIN RESULTS: We did not identify any studies that met our inclusion criteria. We excluded nine studies. AUTHORS' CONCLUSIONS: We could not make explicit conclusions on interventions for treating postpartum constipation because we found no studies for inclusion in this review. Rigorous and well-conducted large randomised controlled trials aimed at treating postpartum women diagnosed with constipation would be beneficial. These trials should also address the criteria for administering the intervention (time and stage of a diagnosis of postpartum constipation), and the safety and effectiveness of such interventions.
