Acceptability of perinatal rapid point-of-care HIV testing in an area of low HIV prevalence in the UK.

OBJECTIVE: To determine the uptake of current antenatal HIV testing, the prevalence of risk factors for HIV in pregnant women and the acceptability of the rapid point-of-care HIV test (RPOCT) among pregnant women and their midwives. DESIGN: A retrospective review of 717 notes to determine current HIV screening practices and a cross-sectional survey using a self-completed questionnaire for pregnant women and midwives. SETTING: The antenatal clinic (ANC) and postnatal wards (PNW) at a university teaching hospital in the West Midlands. PARTICIPANTS: 486 women attending the ANC or admitted to the PNW during a fortnight in May-June 2006. 72 midwives on the delivery ward completed a second questionnaire. RESULTS: The questionnaire showed that 90.4% of those offered the standard HIV test accepted it, with 7.2% having at least one risk factor for HIV. Over half of the decliners perceived themselves as not at risk. 85.2% would accept the rapid test, including 35.6% of the decliners. 92.8% of midwives agreed/strongly agreed the RPOCT has a role on the delivery ward and 97.2% would be happy to offer the test with appropriate training and guidance. CONCLUSIONS: Midwives deem the RPOCT to be appropriate for a variety of perinatal settings. It is also acceptable to a clinically significant proportion of those who decline the standard test (21 of 59) and therefore has the potential to increase screening and detection rates. Hence, by allowing early diagnosis and the initiation of antenatal interventions, it could reduce the rate of mother-to-child transmission (MTCT) in the UK.     

Using scenario‐based assessments to examine the feasibility of integrating preventive nutrition services through the primary health care system in Bangladesh

The National Nutrition Services of Bangladesh aims to deliver nutrition services through the primary health care system. Little is known about the feasibility of reshaping service delivery to close gaps in nutrition intervention coverage and utilization. We used a scenario‐based feasibility testing approach to assess potential implementation improvements to strengthen service delivery. We conducted in‐depth interviews with 31 service providers and 12 policymakers, and 5 focus group discussions with potential beneficiaries. We asked about the feasibility of four hypothetical scenarios for preventive and promotive nutrition service delivery: community‐based events (CBE) for pregnant women, well‐child services integrated into immunization contacts; CBE for well‐children, and well‐child visits at facilities. Opinions on service delivery platforms were mixed; some recommended new platforms, but others suggested strengthening existing delivery points. CBE for pregnant women was perceived as feasible, but workforce shortages emerged as a key barrier. Challenges such as equipment portability, upset children and a fast‐moving service environment suggested low feasibility of integrating nutrition into outreach immunization contacts. In contrast, CBE and facility‐based well‐child visits emerged as feasible options, conditional on having the necessary workforce, structural readiness and budget support. On the demand side, enabling factors include using interpersonal communication and involving community leaders to increase awareness, organizing events at a convenient time and place for both providers and beneficiaries, and incentives for beneficiaries to encourage participation. In conclusion, integrating preventive and promotive nutrition services require addressing current challenges in the health system, including human resource and logistic gaps, and investing in creating demand for preventive services.     

Breastfeeding practices in an area of high HIV prevalence in rural South Africa

Exclusive breastfeeding (EBF) from 0 to 6 mo of age is recommended by the World Health Organization as the optimal feeding method for infants, including infants of human immunodeficiency virus (HIV)-infected women from developing countries who choose to breastfeed. EBF may be associated with less risk of postnatal HIV transmission than mixed feeding, but is still uncommonly practised for reasons that are poorly understood. This study aimed to assess EBF rates and the impediments to EBF in a South African rural area of high HIV prevalence where most mothers are unaware of their status. In a longitudinal study, 130 women attending 3 clinics, chosen for their disparate socioeconomic characteristics, were interviewed at weekly postnatal intervals. Follow-up to 16 wk was completed on 119 infants. In an additional cross-sectional survey mothers of 445 infants, aged 0-12 mo, attending immunization clinics were interviewed. In the longitudinal study 46% of infants received non-breast-milk fluids or feeds within 48 h of birth; only 10% were exclusively breastfed for 6 wk and 6% for 16 wk. Supplements, most commonly formula milk, were introduced for perceived milk insufficiency. Feeding choices were mainly self-determined (43% of women), but health staff (22%) and grandmothers (16%) were cited as sources of advice. In the cross-sectional survey caregivers reported that 47% of infants aged 2 wk, 40% aged 6 wk and 33% aged 12 wk had been exclusively breastfed since birth. CONCLUSION: EBF is uncommon in this area in spite of a baby-friendly hospital initiative in the district. Strategies to promote exclusive breastfeeding in developing countries where HIV and infant feeding policies are being formulated must strongly address local perceptions on the need for supplements and sources of feeding advice.     

A self‐applied valid scale for rapid tracking of household food insecurity among pregnant women in Sri Lanka

Rapid household food insecurity (HFI) tracking has been identified as a priority in the context of the COVID‐19 pandemic and its aftermath. We report the validation of the Latin American and Caribbean Food Security Scale (Escala Latinoamericana y Caribena de Seguridad Alimentaria [ELCSA]) among pregnant women in Sri Lanka. The eight‐item adult version of the ELCSA was translated from English to Sinhala and Tamil. Cognitive testing (on 10 pregnant women and five local experts) and psychometric validation of the self‐administered HFI tool were conducted among pregnant women (n = 269) attending the special clinics of the Rajarata Pregnancy Cohort (RaPCo) in Anuradhapura in February 2020. We assessed the psychometric properties and fit using a one parameter logistic model (Rasch model analysis) using STATA Version 14 and WINSTEP software Version 4.3.4. Concurrent validity was tested using psychological distress. The scale was internally consistent (Cronbach''s alpha = 0.79) and had a good model fit (Rasch items infit statistic range: 0.85 to 1.07). Item 8 (‘did not eat for the whole day’) was removed from the model fit analysis, as it was not affirmed by respondent. Item severity scores ranged from −2.15 for ‘not eating a diverse diet’ to 4.43 for ‘not eating during the whole day’. Concurrent validity between HFI and psychological distress was confirmed (r = 0.15, p < 0.05). The self‐applied version of ELCSA‐pregnancy in Sri Lanka (ELCSA‐P‐SL) is a valid and feasible valid tool. We recommend it to track HFI among pregnant women in lower income countries during the COVID‐19 pandemic.     

Adaptation of the Manchester-Minneapolis Quality of Life instrument for use in the UK population

Introduction

The availability of health‐related quality of life (HRQL) measures that are reliable, valid, brief and comprehensible and appropriate for use with UK children is limited. We report the validation of a HRQL measure suitable for UK use in healthy children, children with chronic disease conditions and socially disadvantaged children.

Patients

A total of 1238 children took part in the study, including healthy children as controls (n = 824) and five exemplar groups: children diagnosed with asthma (n = 87), diabetes (n = 103) or inflammatory bowel disease (IBD; n = 69), children in remission from cancer (n = 68) and children in public care (n = 87).

Methods

In phase I, the Manchester‐Minneapolis Quality of Life instrument (MMQL) Child Form was translated into UK English. In phases II and III, the questionnaire was shortened and validated.

Results

MMQL was anglicised and shortened to five components comprising 29 items. Good internal reliability was found with α reaching at least 0.69 for all subscales. Construct validity was established through moderate correlations with comparable PedsQL subscales (Pearson''s r ranged from 0.38 to 0.58, p<0.01). Discriminant validity was also demonstrated in children with asthma and IBD, children in remission from cancer and children in public care, all of whom reported significantly lower HRQL than healthy children. Children with diabetes showed similar HRQL to their healthy peers. Good reproducibility and moderate responsiveness were demonstrated for the new measure.

Conclusions

The anglicised and shortened MMQL was shown to be valid and reliable and could be a valuable new tool for the assessment of HRQL in children.     

Current ideas about the roles of rapid eye movement and non–rapid eye movement sleep in brain development

Understanding the links between sleep and brain development is important, as rapid eye movement (REM) sleep and non‐REM (NREM) sleep seem to contribute to different aspects of brain maturation. If children have sleep problems, REM sleep and NREM sleep are likely to have different consequences for their developing brain, depending on their age. We highlight important discoveries from human and animal research on the role sleep plays in brain development. A hypothetical model is presented to explain the dynamic relationship of REM sleep and NREM sleep with different processes of brain maturation, with implications for current neonatal care and future research.     

Determinants of adherence to a single‐dose nevirapine regimen for the prevention of mother‐to‐child HIV transmission in Gert Sibande district in South Africa

Aim: To identify factors that influence adherence to antiretroviral (ARV) prophylaxis by HIV positive mothers participating in the HIV prevention of mother to child (PMTCT) programme. Methods: Post‐delivery 815 HIV‐infected mothers aged 18 years and above with babies aged 3–6 months were interviewed in Gert Sibande District, Mpumalanga province, South Africa. Results: Eighty five percent of the mothers indicated that they had been provided with nevirapine and 78.4% took it before or at the onset of labour and infant nevirapine intake was 76.9%. In multivariate analysis it was found that women with better PMTCT knowledge had a higher perceived confidentility about HIV status at the health facility. They had a term delivery and those who had told their partner about nevirapine had a higher maternal nevirapine adherence. Women who had also told their partner about nevirapine, whose partner was asked for an HIV test and those who knew the HIV status of their infant had higher infant nevirapine adherence. Conclusion: Adherence to maternal and infant ARV prophylaxis was found to be sub‐optimal. Health services delivery factors, male involvement, communication and social support contribute to adherence to ARV prophylaxis in this largely rural setting in South Africa.
