For richer, for poorer: marriage and casualized sex in East African artisanal mining settlements

Migrants to Tanzania's artisanal gold mining sites seek mineral wealth, which is accompanied by high risks of occupational hazards, economic failure, AIDS and social censure from their home communities. Male miners in these settlements compete to attract newly arrived young women who are perceived to be diverting male material support from older women and children's economic survival. This article explores the dynamics of monogamy, polygamy and promiscuity in the context of rapid occupational change. It shows how a wide spectrum of productive and welfare outcomes is generated through sexual experimentation, which calls into question conventional concepts of prostitution, marriage and gender power relations

SB-334867-A antagonises orexin mediated excitation in the locus coeruleus

Original article can be found at: http://www.sciencedirect.com/science/journal/00283908 Copyright Elsevier Ltd. [Full text of this article is not available in the UHRA]Electrophysiological recordings from identified noradrenergic locus coeruleus (LC) neurones in rat brain slices have revealed that the orexins can cause direct and reversible depolarisation of the postsynaptic membrane. Whilst it is known that the membrane depolarisation produced by orexin-A can triple the firing rate of spontaneously active LC neurones, quantitative pharmacological analysis that determines the receptor subtype(s) mediating the orexinergic response has not yet been performed. Here we demonstrate that the effects of orexin-A are five-fold more potent than orexin-B on LC neuronal excitability. We show further that the orexin receptor antagonist SB-334867-A inhibits the effects of both agonists with pKB values similar to those calculated for human OX1 receptors expressed in CHO cells. Finally, we found no evidence for tonic activation of OX1 receptors in LC noradrenergic neurones despite electron microscopic evidence that orexin terminals directly contact these neurones. These data demonstrate that SB-334867-A is a useful tool compound with which to study the physiology of OX1 receptors.Peer reviewe

Resources for controlling tuberculosis in Malawi

OBJECTIVE: To document resources for controlling tuberculosis (TB) in Malawi. METHODS: We performed a countrywide study of all 43 hospitals (3 central, 22 district and 18 mission) which register and treat patients with TB. To collect data for 1998 on the TB-related workload, diagnostic facilities, programme staff and treatment facilities, we used laboratory, radiographic and TB registers, conducted interviews and visited hospital facilities. FINDINGS: The data show that in 1998, 88 257 TB suspects/patients contributed approximately 230 000 sputum specimens for smear microscopy, 55 667 chest X-rays were performed and 23 285 patients were registered for TB treatment. There were 86 trained laboratory personnel, 44 radiographers and 83 TB programme staff. Of these, about 40% had periods of illness during 1998. Approximately 20% of the microscopes and X-ray machines were broken. Some 16% of the hospital beds were designated for TB patients in special wards, but even so, the occupancy of beds in TB wards exceeded 100%. Although stocks of anti-TB drugs were good, there was a shortage of full-time TB ward nurses and 50% of district hospitals conducted no TB ward rounds. In general, there was a shortage of facilities for managing associated HIV-related disease; central hospitals, in particular, were underresourced. CONCLUSION: Malawi needs better planning to utilize its manpower and should consider cross-training hospital personnel. The equipment needs regular maintenance, and more attention should be paid to HIV-related illness. The policies of decentralizing resources to the periphery and increasing diagnostic and case-holding resources for central hospitals should be continued

Variation in training requirements within general surgery: comparison of 23 countries.

Many differences exist in postgraduate surgical training programmes worldwide. The aim of this study was to provide an overview of the training requirements in general surgery across 23 different countries. A collaborator affiliated with each country collected data from the country's official training body website, where possible. The information collected included: management, teaching, academic and operative competencies, mandatory courses, years of postgraduate training (inclusive of intern years), working-hours regulations, selection process into training and formal examination. Countries included were Australia, Belgium, Canada, Colombia, Denmark, Germany, Greece, Guatemala, India, Ireland, Italy, Kuwait, the Netherlands, New Zealand, Russia, Saudi Arabia, South Africa, South Korea, Sweden, Switzerland, UK, USA and Zambia. Frameworks for defining the outcomes of surgical training have been defined nationally in some countries, with some similarities to those in the UK and Ireland. However, some training programmes remain heterogeneous with regional variation, including those in many European countries. Some countries outline minimum operative case requirement (range 60-1600), mandatory courses, or operative, academic or management competencies. The length of postgraduate training ranges from 4 to 10 years. The maximum hours worked per week ranges from 38 to 88 h, but with no limit in some countries. Countries have specific and often differing requirements of their medical profession. Equivalence in training is granted on political agreements, not healthcare need or competencies acquired during training
