10. The effect of zinc fortification of a therapeutic complementary food on the growth and immune function of severely malnourished children in Malawi

Abstract

The objective of this study was to improve the content and bioavailability of zinc in Malawi's national therapeutic food (Likuni Phala) and to assess its impact on the immune and growth recovery of malnourished children. The study was a randomised controlled trial with a stratified block design of 121 hospitalised, malnourished children, with mean (±SD) age, length for age (LAZ) and weight for length (WLZ) of 24 ± 11 months, -3.4 ± 1.5 and -2.3 ± 1.0 z-scores, respectively. Fifty six percent of the children were oedematous; the remaining 44% were non-oedematous. Children were severely immune suppressed; 52% were anergic. Three variations of the therapeutic Likuni Phala (LP) were assessed over a four week period; (1) fortified with micronutrients plus zinc (50 mg Zn/100 g dry weight) and with reduced phytate (ZF), (2) fortified with micronutrients without zinc and with reduced phytate (F), and (3) unfortified and without reduced phytate (UF). Following the intervention, both non-oedematous and oedematous children in the F group were 1.80 and 1.75 times more likely to respond positively to the delayed hypersensitivity skin test than the children in the ZF group (p < 0.05), when controlling for age, gender, initial DHS response, HIV and nutritional status and site of test. Nevertheless, among non-oedematous children, final WLZ scores were higher in the ZF (-1.36) than in the F (-1.99) treatments, as was the rate of weight gain in the ZF (4.6 g/kg/d) than the F (1.4 g/kg/d). In contrast, among oedematous children, final WLZ scores were lower in the ZF (-1.71) than the F (-1.19) treatments, and those in the ZF group had a lower rate of weight gain (2.4 g/kg/d) than those in the F (4.8 g/kg/d) group. Our study suggests that levels of zinc (10 mg/kg/day) in combination with the micronutrient fortification of LP resulted in a suppression of the immune system over that of children receiving the LP fortified with micronutrients without zinc (0.7 mg zinc/kg/day), in both non-oedematous and oedematous children. Nevertheless, there were significant increases in weight and rate of weight gain in these non-oedematous children, while the oedematous children decreased in ponderal growth and body composition indices.

12. Thermal symmetry of healthy feet: a precursor to a thermal study of diabetic feet prior to skin breakdown.

Abstract

Early identification of areas of inflammation may aid prevention of diabetic foot ulcers. A new bespoke thermal camera system has been developed to thermally image feet at risk. Hotspots (areas at least 2.2 °C hotter than the contralateral site) may indicate areas of inflammation prior to any apparent visual signs. This article describes the thermal pattern and symmetry of 103 healthy pairs of feet. 68% of participants were thermally symmetric at the 33 foot sites measured. 32% of participants had at least one hotspot, but hotspots overall only accounted for 5% of the measurements made. Refinements to the definition of hotspots are proposed when considering feet at risk of ulceration.

13. Evaluation of potential predictors of outcome of laser-assisted uvulopalatoplasty for snoring.

Abstract

Objective: Laser-assisted uvulopalatoplasty (LAUP) is a common treatment for snoring, but up to 50% of patients obtain little or no sustained benefit. We investigated whether pre-operative measurements from lateral cephalometry, acoustic rhinometry, analysis of snoring sounds, and body mass index (BMI) could predict which snorers benefited from LAUP., Study Design and Setting: Fifty-five snoring patients were assessed pre- and 6 months post-LAUP. Snoring severity was assessed by objective sound level recorded during polysomnography, and a Snoring Symptoms Inventory (SSI) questionnaire., Results: The outcome of surgery was assessed by changes in objective sound measurements and in SSI, 6 months after LAUP., Conclusions: Relationships between the predictive measurements and outcome were at best only weak and none had sufficient predictive value to be useful in clinical practice.
