Volunteering to help those less fortunate: Pathways for Australian GPs to acquire helpful knowledge and skills.

BACKGROUND: The high number of postgraduate global health courses, websites such as Global Health Gateway, annual conferences such as the Global Ideas Forum, and global health interest groups in all 20 Australian medical schools are indicators of increased interest among Australian doctors in working overseas. OBJECTIVE: This article provides an overview of the health situation in low-income and middle-income countries, and summarises current approaches to improving the health of those living in countries with a developing economy. Opportunities for overseas assignments by generalist medical doctors in emergency and non-emergency settings are described, and appropriate pathways to prepare for such work are outlined. DISCUSSION: The ideal training for overseas work is a Master or Diploma of Public Health, with a global health specialisation. These are available in 16 Australian and two New Zealand universities. Individual units can be taken as short courses, for example, in field epidemiology, maternal and child health, communicable diseases, nutrition, and health in complex emergencies.

So close: remaining challenges to eradicating polio.

The Global Polio Eradication Initiative, launched in 1988, is close to achieving its goal. In 2015, reported cases of wild poliovirus were limited to just two countries - Afghanistan and Pakistan. Africa has been polio-free for more than 18 months. Remaining barriers to global eradication include insecurity in areas such as Northwest Pakistan and Eastern and Southern Afghanistan, where polio cases continue to be reported. Hostility to vaccination is either based on extreme ideologies, such as in Pakistan, vaccination fatigue by parents whose children have received more than 15 doses, and misunderstandings about the vaccine's safety and effectiveness such as in Ukraine. A further challenge is continued circulation of vaccine-derived poliovirus in populations with low immunity, with 28 cases reported in 2015 in countries as diverse as Madagascar, Ukraine, Laos, and Myanmar. This paper summarizes the current epidemiology of wild and vaccine-derived poliovirus, and describes the remaining challenges to eradication and innovative approaches being taken to overcome them.

The impact on child wasting of a capacity building project implemented by community and district health staff in rural Lao PDR.

Laos is a low-income food-deficit country with pockets of high levels of wasting in the highland areas. We implemented a 3-year health/nutrition project in 12 villages in the highlands of Savannakhet province to reduce acute malnutrition in children. Volunteer nutrition teams in each village monitored child growth and promoted healthy feeding practices; a multisectoral district committee conducted monthly outreach to assess child growth, manage acute malnutrition and deliver primary health care services. We conducted a cross-sectional assessment before project activities began and at the end of the project. The baseline survey randomly sampled 60% of all households; the endline assessment aimed to survey all eligible registered participants. Anthropometric measures were taken from children aged 6-59 months; mothers with children aged <12 months were asked about infant feeding practices, antenatal and post-partum care; and child immunizations were recorded for children aged between 0-23 months. At baseline, 721 households were sampled, while the endline assessment surveyed between 82% and 100% of eligible participants in each age group. Acute malnutrition reduced from 12.4% (95% CI: 10.4- 14.3) to 6.1% (4.9-7.3). Unhealthy feeding practices declined: in 2008, 40.0% (34.7-45.3) of mothers breastfed their newborn within 2 hours of birth and 30.8% (25.7-35.8) threw the colostrum away; in 2011, these figures were 72% and 8% respectively. Maternal care and child immunisation coverage also improved. Improving the health environment and child feeding practices appears to have markedly reduced the level of wasting. Unsafe feeding practices were common but readily changed by the community-based nutrition teams.

Oncotype dx results in multiple primary breast cancers.

PURPOSE: To determine whether multiple primary breast cancers have similar genetic profiles, specifically Oncotype Dx Recurrence Scores, and whether obtaining Oncotype Dx on each primary breast cancer affects chemotherapy recommendations. METHODS: A database of patients with hormone receptor-positive, lymph node-negative, breast cancer was created for those tumors that were sent for Oncotype Dx testing from the University of Michigan Health System from 1/24/2005 to 2/25/2013. Retrospective chart review abstracted details of tumor location, histopathology, distance between tumors, Oncotype Dx results, and chemotherapy recommendations. RESULTS: Six hundred and sixty-six patients for whom Oncotype Dx testing was sent were identified, with 22 patients having multiple breast tumor specimens sent. Of the 22 patients who had multiple samples sent for analysis, chemotherapy recommendations were changed in 6 of 22 patients (27%) based on significant differences in Oncotype Dx Recurrence Scores. Qualitatively, there seems to be a greater difference in genetic profile in tumors appearing simultaneously on different breasts when compared to multiple tumors on the same breast. There was no association between distance between tumors and difference in Oncotype Dx scores for tumors on the same breast. CONCLUSIONS: Oncotype Dx testing on multiple primary breast cancers altered management in regards to chemotherapy recommendations and should be considered for multiple primary breast cancers.

Promoting safer sexual practices among expectant fathers in the Lao People's Democratic Republic.

Men's decisions and behaviours influence the sexual, reproductive and maternal health of women and the health of their families, but men are rarely included in reproductive and maternal health care services. Men's attendance at antenatal care has the potential to prevent women from becoming infected with HIV during pregnancy and post-partum, when they are more vulnerable to infection and have a high risk of transmission to the infant. Greater involvement of men requires an understanding of social, cultural and organisational barriers in different contexts. In 2006, the Burnet Institute undertook fieldwork to inform a pilot project to encourage expectant fathers to attend antenatal care. A local Lao team conducted focus group discussions and interviews in Vientiane with expectant fathers, pregnant women, older women and health care providers. It was found that myths about the dangers of sex during pregnancy and women's decreased desire resulted in periods of sexual abstinence. Participants reported that unprotected extramarital sex was common but difficult for couples to discuss. Men lacked knowledge about sexually transmitted infections, including HIV. Men wanted information so they could better protect the health of their partners and babies during and after pregnancy, and reported being willing to attend antenatal care when invited. Our findings have useful implications for policy and implementation.

In rural Tibet, the prevalence of lower limb pain, especially knee pain, is high: an observational study.

QUESTION: What is the point prevalence and 12-month prevalence of lower limb musculoskeletal pain in rural Tibet? Does this differ with gender or age? What factors that could contribute to lower limb musculoskeletal pain are commonly present? DESIGN: Observational study using an investigator-administered questionnaire and observation walks through villages. PARTICIPANTS: 499 people aged 15 years and over living in 19 rural villages of Shigatse Municipality, Tibet. RESULTS: The point prevalence of lower limb musculoskeletal pain was 40% (95% CI 34 to 46) while the 12-month prevalence was 48% (95% CI 42 to 54). In particular, the point prevalence of knee pain was 25% (95% CI 20 to 30) and the 12-month prevalence was 29% (95% CI 23 to 35), which was significantly higher than at any other site in the lower limb. On average, being female was not associated with lower limb musculoskeletal pain either currently (OR 1.3, 95% CI 0.9 to 1.9) or over the previous 12 months (OR 1.2, 95% CI 0.9 to 1.8), whereas being older than 50 years was, both for current pain (OR 4.1, 95% CI 2.8 to 6.1) and pain over the previous 12 months (OR 4.0, 95% CI 2.7 to 6.0). Observation walks through the villages revealed people squatting for sustained periods, carrying heavy loads for long distances, wearing poor quality footwear, and with severe bowing of the legs but no obesity. CONCLUSION: Lower limb musculoskeletal pain, particularly knee pain, is common in this rural Tibetan population. They live an extremely arduous life that appears to place considerable pressure on their knees.

District health programmes and health-sector reform: case study in the Lao People's Democratic Republic.

The Lao People's Democratic Republic (Lao PDR) is classified by the World Bank as a low-income country under stress. Development partners have sought to utilize effective aid instruments to help countries classified in this way achieve the Millennium Development Goals; these aid instruments include sector-wide approaches (SWAps) that support decentralized district health systems and seek to avoid fragmentation and duplication. In Asia and the Pacific, only Bangladesh, Papua New Guinea and the Solomon Islands have adopted SWAps. Since 1991, a comprehensive primary health care programme in the remote Sayaboury Province of Lao PDR has focused on strengthening district health management, improving access to health facilities and responding to the most common causes of mortality and morbidity among women and children. Between 1996 and 2003, health-facility utilization tripled, and the proportion of households that have access to a facility increased to 92% compared with only 61% nationally. By 2003, infant and child mortality rates were less than one-third of the national rates. The maternal mortality ratio decreased by 50% despite comprehensive emergency obstetric care not being available in most district hospitals. These trends were achieved with an investment of approximately 4 million US dollars over 12 years (equivalent to US 1.00 US dollars per person per year). However, this project did not overcome weaknesses in some national disease-control programmes, especially the expanded programme on immunization, that require strong central management. In Lao PDR, which is not yet committed to using SWAps, tools developed in Sayaboury could help other district health offices assume greater planning responsibilities in the recently decentralized system. Development partners should balance their support for centrally managed disease-specific programmes with assistance to horizontally integrated primary health care at the district level.

Hepatitis E virus infection as a marker for contaminated community drinking water sources in Tibetan villages.

In April-May 2001, a study was conducted to determine the prevalence of antibodies against hepatitis E virus (HEV) among 426 persons 8-49 years of age randomly selected from two groups of rural villages in central Tibet. Group 1 villages were assessed in 1998 as having poor quality water sources; new water systems were then constructed prior to this study. Group 2 villages had higher quality water and were not designated as priority villages for new systems prior to the study. No participants tested positive for IgM; only IgG was detected in the analyzed samples. Overall, 31% of the participants had ever been infected with HEV (95% confidence interval [CI] = 26.7-35.7%). The rate was higher in men (36.6%) than women (26.3%) and highest in those 30-39 years of age (49.1%). The rate of past infection was higher in group 1; the risk ratio was 2.77 (95% CI = 1.98-3.88). This difference is most likely the result of the poor quality of the original water sources in these villages. In resource-poor countries, HEV may be a useful health indicator reflecting the degree of contamination in village water sources. This may be especially important in rural areas (such as Tibet) where maternal mortality ratios are high because HEV may be an important cause of deaths during pregnancy in disease-endemic areas.

Low back pain in rural Tibet.

In a baseline assessment of 30 rural villages surrounding Shigatse City, Tibet, many people, especially women, identified low back pain as a serious health problem. Consequently, we aimed to establish the prevalence of such pain and to develop appropriate interventions. We did a cross-sectional study of the prevalence of low back pain and related functional disability using two-stage random cluster sampling. We included 499 adults aged at least 15 years from 19 villages. The point prevalence of low back pain was 34.1% (95% CI 27.9-40.3% [170 people]); the 12-month prevalence was 41.9% (35.5-48.3% [209 people]). 100 (20%) villagers had substantial functional disability associated with low back pain. Low back pain is likely to be an important and under recognised problem in rural societies like Tibet.
