Abstract Background The pediatric pulmonary multisystem Langerhans cell histiocytosis (PPM LCH) is associated with either low risk or high risk organ(s). The nodulo-cystic lung lesions although pathognomonic, yet are very variable in severity and remain a source of controversy in certifying pulmonary LCH diagnosis. The study aimed to examine the prognostic value of clinical respiratory manifestations and radiological lung lesions severity. This is through associating a CT chest triad of bilateral, extensive and diffuse lesions. It is a retrospective study of 350 LCH patients who received systemic treatment at Children’s Cancer Hospital Egypt during the period from 2007 to 2020. Results Sixty-seven patients (67/350–19.1%) had PPM LCH at presentation. Severe lung lesions were present in 24 of them. The median follow-up period was 61 months (IQR: 3.4–8.3). The 5-year overall survival (OS) and event free survival (EFS) was 89% and 56.6% respectively. The EFS, for severe radiological lesions triad was 38% ± 20.7 versus 66% ± 16.2 for non-severe lesions triad p 0.002, while for presence of chest X-ray changes 27% ± 22.344 versus absence of chest X ray changes 66% ± 14.7 p 0.001, for clinical respiratory manifestations 13% ± 13.9 versus none 62% ± 22.9 p

Abstract Background The deployment of Community Health Workers (CHWs) is widely promoted as a strategy for reducing health inequities in low- and middle-income countries (LMIC). Yet there is limited evidence on whether and how CHW programmes achieve this. This systematic review aimed to synthesise research findings on the following questions: (1) How effective are CHW interventions at reaching the most disadvantaged groups in LMIC contexts? and (2) What evidence exists on whether and how these programmes reduce health inequities in the populations they serve? Methods We searched six academic databases for recent (2014–2020) studies reporting on CHW programme access, utilisation, quality, and effects on health outcomes/behaviours in relation to potential stratifiers of health opportunities and outcomes (e.g., gender, socioeconomic status, place of residence). Quantitative data were extracted, tabulated, and subjected to meta-analysis where appropriate. Qualitative findings were synthesised using thematic analysis. Results One hundred sixty-seven studies met the search criteria, reporting on CHW interventions in 33 LMIC. Quantitative synthesis showed that CHW programmes successfully reach many (although not all) marginalized groups, but that health inequalities often persist in the populations they serve. Qualitative findings suggest that disadvantaged groups experienced barriers to taking up CHW health advice and referrals and point to a range of strategies for improving the reach and impact of CHW programmes in these groups. Ensuring fair working conditions for CHWs and expanding opportunities for advocacy were also revealed as being important for bridging health equity gaps. Conclusion In order to optimise the equity impacts of CHW programmes, we need to move beyond seeing CHWs as a temporary sticking plaster, and instead build meaningful partnerships between CHWs, communities and policy-makers to confront and address the underlying structures of inequity.

Abstract Background Sub-optimal nutrition among children remains a problem across South Asia (SA). Appropriate complementary feeding practices (CFP) can greatly reduce this risk. The primary objective of this systematic review (SR) of CF studies was to assess timing, dietary diversity, meal frequency and influencing factors in children under two in Bangladesh. Methods Searches included English-language research published between January 2000 and June 2016 within MEDLINE, EMBASE, Global Health, Web of Science, OVID Maternity & Infant Care, BanglaJOL, Cochrane Library, CINAHL, POPLINE and WHO Global Health Library. Eligibility criteria: primary research concerning the adequacy of complementary feeding practices in South Asian children aged 0–2 years and/or their families. We excluded interventional papers and those focusing exclusively on breast-feeding. In total 45,712 titles and abstracts were screened against inclusion criteria, 860 of which received independent full text review by two reviewers. 36 papers relevant to Bangladesh were identified. The ‘EPPI-Centre Weight of Evidence Framework’ was used to objectively assess each study’s value in answering the review question. As per WHO Infant and Young Children Feeding Guidelines (IYCF), introduction of CF was assessed as the proportion of infants aged 6–8 months who received solid, semi-solid or soft foods. Search terms were: “children”, “feeding” and “Asians” with their derivatives. Two researchers undertook study selection, data extraction and quality appraisal. Results Three cohort, 30 cross-sectional and 3 mixed methods studies were included. Despite adopting the WHO IYCF Guidelines, sub-optimal CF practices were found in many studies. Timely initiation of CF practices ranged from 24 to 83%. Achieved minimum dietary diversity ranged from 25% to 44% and minimum meal frequency from 33% to 81%. Influencing factors included maternal education, poor knowledge of CF practices and socioeconomic variables. Conclusions This is the first systematic review to evaluate CF practices in Bangladesh. Despite adoption of the WHO IYCF guidelines, inadequate CFP remain in communities across Bangladesh. Trial registration PROSPERO Registration No: CRD42014014025 .
