This review focusses on the interactions between the etiologic agent of Chagas disease, Trypanosoma cruzi, and its triatomine vector. The flagellate mainly colonizes the intestinal tract of the insect. The effect of triatomines on trypanosomes is indicated by susceptibility and refractoriness phenom...ena that vary according to the combination of the strains. Other effects are apparent in the different regions of the gut. In the stomach, the majority of ingested blood trypomastigotes are killed while the remaining transform to round stages. In the small intestine, these develop into epimastigotes, the main replicative stage. In the rectum, the population density is the highest and is where the infectious stage develops, the metacyclic trypomastigote. In all regions of the gut, starvation and feeding of the triatomine affect T. cruzi. In the small intestine and rectum, starvation reduces the population density and more spheromastigotes develop. In the rectum, feeding after short-term starvation induces metacyclogenesis and after long-term starvation the development of specific cells, containing several nuclei, kinetoplasts and flagella. When considering the effects of T. cruzi on triatomines, the flagellate seems to be of low pathogenicity. However, during stressful periods, which are normal in natural populations, effects occur often on the behaviour, eg, in readiness to approach the host, the period of time before defecation, dispersal and aggregation. In nymphs, the duration of the different instars and the mortality rates increase, but this seems to be induced by repeated infections or blood quality by the feeding on infected hosts. Starvation resistance is often reduced by infection. Longevity and reproduction of adults is reduced, but only after infection with some strains of T. cruzi. Only components of the surface coat of blood trypomastigotes induce an immune reaction. However, this seems to act against gut bacteria and favours the development of T. cruzi.

From this page you can access the modules that form the theoretical training element of the HEAT programme. The thirteen modules cover a wide range of subjects including child and maternal health, hygiene, immunisation, and nutrition. These modules have been created as Open Educational Resources and... they can be accessed by anyone in the world, at any time, free of charge. The three maternal health modules: Antenatal Care; Labour and Delivery Care; and Postnatal Care, are also available in Swahili.
Some of them are designed for the upgrade training for the Health Extension Worker programme in Ethiopia - it's the official MOH curriculum, and was designed as a year (or more) long distance learning programme.

Too few physicians are equipped with the knowledge and skills needed to repair genital fistulae and care for patients following surgery. Most procedures are performed in Africa and Asia by local physicians, with technical support from surgeons from developed countries where these fistulae are rarely... seen. It would take many years for all the physicians presently able to treat genital fistulae to operate on all the women who need their expertise today, and the number of women who need their expertise increases daily. Although the need for physicians trained in fistula repair has long been recognised, no standard training manual has existed so far. This manual was designed to help meet this need.
This manual was produced with the collaboration of fistula surgeons, professional organizations and specialist health organisations from all over Africa, Asia, Europe and the USA.

WHO has developed standardized health kits of medicines and medical supplies to meet different health needs in humanitarian emergencies and disasters.
These kits are developed to provide reliable and affordable medicines and supplies quickly to those in need. The kits are used by United Nations age...ncies, nongovernmental organizations and national governments.
Based primarily on WHO’s Essential Medicines list and guidelines on treatment of specific medical conditions, the contents of the kits are frequently reviewed and updated to adapt to changing needs based on experience in emergency situations.
A certain number of kits are prepositioned in strategic locations to be mobilized quickly in times of need. Long term agreements with suppliers are also in place to ensure rapid shipment wherever needed.

This guideline aims to improve the quality of essential, routine postnatal care for women and newborns with the ultimate goal of improving maternal and newborn health and well-being. It recognizes a “positive postnatal experience” as a significant end point for all women giving birth and their n...ewborns, laying the platform for improved short- and long-term health and well-being. A positive postnatal experience is defined as one in which women, newborns, partners, parents, caregivers and families receive information, reassurance and support in a consistent manner from motivated health workers; where a resourced and flexible health system recognizes the needs of women and babies, and respects their cultural context.
This is a consolidated guideline of new and existing recommendations on routine postnatal care for women and newborns receiving facility- or community-based postnatal care in any resource setting.

Les normes et standards applicables aux centres d’accueil et de protection d’enfants en République du Bénin
The reports bring together the latest findings and conclusions about the state of resistance to artemisinins and artemisinin-based combination therapy (ACT), summarize WHO’s current policy and treatment recommendations, and highlight areas of concern.
In March 2013, a delegation of Benin health officials along with eight other country
delegations attended the Francophone West Africa CBFP Partners’ Meeting held in
Senegal. This landmark partners’ meeting was held to advocate and build capacity
for the introduction of CBFP, including communi...ty-based access to injectable
contraception (CBA2I), as a global standard of practice in the Ouagadougou Partner
countries.
