Mid-term evaluation of Maternal and Child Nutrition Programme (MCNP II) in Kenya.

BACKGROUND: Kenya is faced with a triple burden of malnutrition which is multi-faceted with health and socio-economic implications. Huge geographical disparities exist, especially, in the arid and semi-arid lands exacerbated by inadequate resource allocation to the nutrition sector and challenges in multi-sectoral coordination and nutrition governance. UNICEF's Maternal and Child Nutrition Programme is a four-year (2018-2022) resilience-building, multi-sectoral program focused on pregnant and lactating women, mothers of children under five years and children under five years. The objective of the mid-term evaluation was to establish the relevance, effectiveness, efficiency, and sustainability of the programme. METHODS: The field evaluation conducted between June and July 2021, adopted a concurrent mixed-methods approach, where qualitative information was gathered through 29 key informant interviews and 18 focus group discussions (6 FGDs per population group; women of reproductive age, adolescent girls and men). Quantitatively, data were obtained through desk review of secondary data from programme reports, budgets, and project outputs where descriptive analysis was undertaken using Excel software. Qualitative information was organized using Nvivo software and analyzed thematically. RESULTS: The findings provide evidence of the relevance of the Maternal and Child Nutrition Programme II to the nutrition situation in Kenya and its alignment with the Government of Kenya and donor priorities. Most planned programme targets were achieved despite operating in a COVID-19 pandemic environment. The use of innovative approaches such as family mid-upper arm circumference, integrated management of acute malnutrition surge model, Malezi bora and Logistic Management Information Management System contributed to the realization of effective outputs and outcomes. Stringent financial management strategies contributed toward programme efficiencies; however, optimal utilization of the resources needs further strengthening. The programme adopted strategies for strengthening local capacity and promoting ownership and long-term sustainability. CONCLUSION: The programme is on track across the four evaluation criteria. However, a few suggestions are recommended to improve relevance, effectiveness, efficiency, and sustainability. A formal transition strategy needs to be developed in consultation with multi-stakeholder groups and implemented in phases. UNICEF Nutrition section should explore a more integrated  programming mode of delivery through joint initiatives with other agencies under the Delivery as One UN agenda, along the more gender transformative approaches with more systematic involvement of males and females in gender-based discussions.

Direct comparison of metabolic health effects of the flavonoids quercetin, hesperetin, epicatechin, apigenin and anthocyanins in high-fat-diet-fed mice.

Dietary flavonoid intake is associated with reduced risk of cardiovascular diseases, possibly by affecting metabolic health. The relative potency of different flavonoids in causing beneficial effects on energy and lipid metabolism has not been investigated. Effects of quercetin, hesperetin, epicatechin, apigenin and anthocyanins in mice fed a high-fat diet (HF) for 12 weeks were compared, relative to normal-fat diet. HF-induced body weight gain was significantly lowered by all flavonoids (17-29 %), but most by quercetin. Quercetin significantly lowered HF-induced hepatic lipid accumulation (71 %). Mesenteric adipose tissue weight and serum leptin levels were significantly lowered by quercetin, hesperetin and anthocyanins. Adipocyte cell size and adipose tissue inflammation were not affected. The effect on body weight and composition could not be explained by individual significant effects on energy intake, energy expenditure or activity. Lipid metabolism was not changed as measured by indirect calorimetry or expression of known lipid metabolic genes in liver and white adipose tissue. Hepatic expression of Cyp2b9 was strongly downregulated by all flavonoids. In conclusion, all flavonoids lowered parameters of HF-induced adiposity, with quercetin being most effective.

Short-chain fatty acids stimulate angiopoietin-like 4 synthesis in human colon adenocarcinoma cells by activating peroxisome proliferator-activated receptor γ.

Angiopoietin-like protein 4 (ANGPTL4/FIAF) has been proposed as a circulating mediator between the gut microbiota and fat storage. Here, we show that transcription and secretion of ANGPTL4 in human T84 and HT29 colon adenocarcinoma cells is highly induced by physiological concentrations of short-chain fatty acids (SCFA). SCFA induce ANGPTL4 by activating the nuclear receptor peroxisome proliferator activated receptor γ (PPARγ), as demonstrated using PPARγ antagonist, PPARγ knockdown, and transactivation assays, which show activation of PPARγ but not PPARα and PPARδ by SCFA. At concentrations required for PPARγ activation and ANGPTL4 induction in colon adenocarcinoma cells, SCFA do not stimulate PPARγ in mouse 3T3-L1 and human SGBS adipocytes, suggesting that SCFA act as selective PPARγ modulators (SPPARM), which is supported by coactivator peptide recruitment assay and structural modeling. Consistent with the notion that fermentation leads to PPAR activation in vivo, feeding mice a diet rich in inulin induced PPAR target genes and pathways in the colon. We conclude that (i) SCFA potently stimulate ANGPTL4 synthesis in human colon adenocarcinoma cells and (ii) SCFA transactivate and bind to PPARγ. Our data point to activation of PPARs as a novel mechanism of gene regulation by SCFA in the colon, in addition to other mechanisms of action of SCFA.
