Hope Worldwide Kenya

BackgroundUp to 70% of medical devices in low-income and middle-income countries are partially or completely non-functional, impairing service provision and patient outcomes. In Sub-Saharan Africa, medical devices not designed for local conditions, lack of well-trained biomedical engineers and diverse donated equipment have led to poor maintenance and non-repair. The Maker Project’s aim was to test the effectiveness of an innovative partnership ecosystem network, the ‘Maker Hub’, in reducing gaps in the supply of essential medical devices for maternal, newborn and child health. This paper describes the first phase of the project, the building of the Maker Hub.MethodsKey activities in setting up the Maker Hub—a collaborative partnership between the University of Nairobi (UoN) and the Kenyatta National Hospital (KNH), catalysed by Concern Worldwide Kenya—are described using a product development partnership approach. Using a health systems approach, a needs assessment identified a medical equipment shortlist. Design thinking with a capacity building component was used by the UoN (innovators, public health specialists, engineers) working closely and with KNH nurses, physicians and biomedical engineers to develop the prototypes.ResultsTo date, four medical device prototypes have been developed. Two have been evaluated by the National Bureau of Standards and one has undergone clinical testing.ConclusionsWe have demonstrated an innovative partnership ecosystem that has developed medical devices that have undergone national standards evaluation and clinical testing, a first in Sub-Saharan Africa. Promoting a robust innovation ecosystem for medical equipment requires investment in building trust in the innovation ecosystem.

Anopheles gambiae s.s., Anopheles arabiensis, and Anopheles funestus s.s. are the most important species for malaria transmission. Pyrethroid resistance of these vector mosquitoes is one of the main obstacles against effective vector control. The objective of the present study was to monitor the pyrethroid susceptibility in the 3 major malaria vectors in a highly malaria endemic area in western Kenya and to elucidate the mechanisms of pyrethroid resistance in these species. Gembe East and West, Mbita Division, and 4 main western islands in the Suba district of the Nyanza province in western Kenya were used as the study area. Larval and adult collection and bioassay were conducted, as well as the detection of point mutation in the voltage-gated sodium channel (1014L) by using direct DNA sequencing. A high level of pyrethroid resistance caused by the high frequency of point mutations (L1014S) was detected in An. gambiae s.s. In contrast, P450-related pyrethroid resistance seemed to be widespread in both An. arabiensis and An. funestus s.s. Not a single L1014S mutation was detected in these 2 species. A lack of cross-resistance between DDT and permethrin was also found in An. arabiensis and An. funestus s.s., while An. gambiae s.s. was resistant to both insecticides. It is noteworthy that the above species in the same area are found to be resistant to pyrethroids by their unique resistance mechanisms. Furthermore, it is interesting that 2 different resistance mechanisms have developed in the 2 sibling species in the same area individually. The cross resistance between permethrin and DDT in An. gambiae s.s. may be attributed to the high frequency of kdr mutation, which might be selected by the frequent exposure to ITNs. Similarly, the metabolic pyrethroid resistance in An. arabiensis and An. funestus s.s. is thought to develop without strong selection by DDT.
