A qualitative exploration of behavioral factors affecting mothers of malnourished children under 5 years old in Kiribati.

Background: In Kiribati, malnutrition is the leading cause of death for children aged less than 5 years. The purpose of this study was to explore contributing behavioral factors among mothers of malnourished children under 5 years old in Kiribati. Methods: This qualitative study was conducted in an urban area of South Tarawa among mothers of malnourished children aged less than 5 years in 11 public health centers in 2016. The study included 9 focus group discussions, with a sub sample of 3 to 4 in each group, having a total of 35 participants. Using a semi-structured questionnaire, data was collected and thematic analysis was applied to analysis the data.  Results: Seven main themes were identified including; knowledge, behaviors, perceived severity, perceived benefits to action, perceived barriers and cultural related issues. These encompassed a variety of reasons which could explain the malnutrition in children of those particular mothers. Conclusion: In order to tackle malnutrition in Kiribati, it is crucial to identify the main factors that are hindering this preventable disease. This study provides information essential to enhanced decision making, health care delivery planning and has policy implications for the improvement of quality of health care in Kiribati.

Spatial control of the energy metabolism of yeast cells through electrolytic generation of oxygen.

The metabolic dynamics of yeast cells is controlled by electric pulses delivered through a spatially extended yeast cell/Au electrode interface. Concomitant with voltage pulses, oxygen is generated electrolytically at the electrode surface and delivered to the cells. The generation of oxygen was investigated in dependence of the applied voltage, width of the voltage pulses and temperature of the electrolytic solution. The local oxygen pulses at the electrodes lead to a transient activation of the aerobic energy metabolism of the yeast cells causing a perturbation in their energy balance. The effect of these local perturbations on the temporal dynamics of glycolysis in yeast cells is quantified in dependence of the energy state of cells.
