An Interactive Internet-Based Continuing Education Course on Sexually Transmitted Diseases for Physicians and Midwives in Peru

Clinicians in developing countries have had limited access to continuing education (CE) outside major cities, and CE strategies have had limited impact on sustainable change in performance. New educational tools could improve CE accessibility and effectiveness.The objective of this study was to evaluate an interactive Internet-based CE course on Sexually Transmitted Diseases (STDs) management for clinicians in Peru. Participants included physicians and midwives in private practice drawn from a census of 10 Peruvian cities. The CE included a three-hour workshop for improving Internet skills, followed by a 22-hour online course on STD-syndrome-management, with subsequent educational support. The course used case-based clinical vignettes tailored to local STD problems. Knowledge and reported practices on STD management were assessed before, immediately after and at four months after completion of the course. Statistical analysis included parametric tests-linear regression multivariate analysis, paired t-test and repeated measures ANOVA using SPSS 14.0. Of 1,071 eligible clinicians, 510 agreed to participate, as did an additional 132 public sector clinicians. Of these 642 participants, 619 (96.4%) completed the course, and 596 (96.3%) took the four-month follow-up evaluation. Physician and midwife scores improved from 64.2% correct answers on the pre-test to 77.9% correct on the four-month follow-up test (p<0.001). Most participants (95%) found the online course useful for their work needs. Self reported STD management practices did not change.Among physicians and midwives in Peru, an Internet-based CE course was feasible, acceptable with high participation rates, and led to sustained improvement in knowledge at four months. Further studies are needed to test it as a model for improving the training of physicians, midwives, and other health care providers

Glucose induced IEG expression in the thiamin-deficient rat brain

Glucose loading of rats made thiamin deficient by dietary deprivation of thiamin and the administration of pyrithiamin (40 mug/100 g, i.p.) precipitates an acute neuropathy, a model of Wernicke's encephalopathy in man (Zimitat and Nixon, Metab. Brain Dis. 1999;14:1-20). Immunohistochemical detection of Fos proteins was used as a marker to identify neuronal populations in the thiamin-deficient rat brain affected by glucose loading. As thiamin deficiency progressed, the extent and intensity of Fos-Like immunoreactivity (FLI) in brain structures typically affected by thiamin deficiency (the thalamus, mammillary bodies, inferior colliculus, vestibular nucleus and inferior olives) were markedly increased when compared to thiamin-replete controls. Glucose loading for 1-3 days further increased the intensity of FLI in these same regions, consistent with a dependence of Fos expression on carbohydrate metabolism as well as on thiamin deficiency. The timed acute changes that follow a bolus glucose load administered to thiamin-deficient animals may provide a sequential account of events in the pathogenesis of brain damage in this model of Wernicke's encephalopathy.

Progression of neurological disease in thiamin-deficient rats is enhanced by ethanol

The clinical and neuropathological consequences of either ethanol consumption or thiamin deficiency or both were examined in Wistar rats aged nine weeks divided into five groups and fed one of the following diets: a thiamin-replete (control) diet (A); a thiamin-fortified diet with water (B) or 15% ethanol (C); or a thiamin-deficient diet with water (D) or 15% ethanol (E). Rats fed diets A, B or C for 35 weeks showed no clinical signs of neurological disease at any stage and no significant brain pathology when harvested. Rats fed diets D and E progressed through a common sequence of clinical signs of neurological disease typical of acute thiamin deficiency, viz loss of coat condition, ataxia, opisthotonus and ultimately death within 10-23 weeks. The onset and progression of these stages of neurological disease were significantly earlier and faster (

Health care, overconsumption and uneconomic growth: a conceptual framework

Concerns have grown in recent decades that economic growth in many rich countries may, in fact, be uneconomic. Uneconomic growth occurs when expansion in economic activity causes environmental and social costs that are greater than the benefits of that additional activity. Health care has enjoyed a close historical relationship with economic growth, with health care spending consistently growing faster than GDP over the long term. This paper explores the possible relationship between health care and uneconomic growth. It summarises the rapidly growing evidence on the harms caused by poor quality health care and by the overuse of health care, and on the environmental harms caused by health care systems. Further, it develops a conceptual framework for considering the overconsumption of health care and the joint harms to human health and the natural environment that ensue. This framework illustrates how health-damaging overconsumption in the wider economy combines with unnecessary or low-quality health care to create a cycle of "failure demand" and defensive expenditure on health care services. Health care therefore provides important sectoral insights on the phenomenon of uneconomic growth. There are rich opportunities for interdisciplinary research to quantify the joint harms of overconsumption in health and health care, and to estimate the optimal scale of the health sector from novel perspectives that prioritise human and planetary health and well-being over GDP and profit

A rural, community-based suicide awareness and intervention program

Suicide is a prominent public health issue in rural Australia and specifically in Tasmania, which has one of the highest suicide rates in the country. The Community Response to Eliminating Suicide (CORES) program was developed in rural Tasmania in response to a significant number of suicides over a short period of time. CORES is unique in that it is both a community-based and gatekeeper education model. CORES aims to build and empower communities to take ownership of suicide prevention strategies. It also aims to increase the individual community member's interpersonal skills and awareness of suicide risks, while building peer support and awareness of suicide prevention support services within the community itself. Pre- and post-test surveys after the CORES 1-day suicide awareness and intervention program (SAIP) showed significant increases in levels of comfort and confidence in discussing suicide with those who may be contemplating that action. CORES builds community capital through establishing new connections within communities. Establishment of local executive groups, funding and SAIP are key activities of successful CORES programs in communities around Australia. Over half of the initial leaders are still actively involved after a decade, which reflects positively on the quality and outcomes of the program. This study supports CORES as a beneficial and feasible community-based suicide intervention program for rural communities

Choroid plexus dysfunction: The initial event in the pathogenesis of Wernicke's encephalopathy and ethanol intoxication

Background: In both acute ethanol intoxication and in thiamin deficient glucose metabolism, previous studies have detected blood-brain barrier (BBB) and/or blood-CSF-barrier (BCSFB) impairment but were unable to assess their significance in relation to other changes in the brain
