Ethnic inequity in neonatal survival: a case-referent study in northern Vietnam

Aim: In this study from Quang Ninh province in northern Vietnam (sub‐study of the trial Neonatal Health – Knowledge into Practice, NeoKIP, ISRCTN 44599712), we investigated determinants of neonatal mortality through a case‐referent design, with special emphasis on socio‐economic factors and health system utilization. Methods: From July 2008 until December 2009, we included 183 neonatal mortality cases and 599 referents and their mothers were interviewed. Results: Ethnicity was the main socio‐economic determinant for neonatal mortality (OR 2.08, 95% CI 1.39–3.10, adjusted for mothers’ education and household economic status). Health system utilization before and at delivery could partly explain the risk elevation, with an increased risk of neonatal mortality for mothers who did not attend antenatal care and who delivered at home (OR 4.79, 95% CI 2.98–7.71). However, even if mothers of an ethnic minority attended antenatal care or delivered at a health facility, the increased risk for this group was sustained. Conclusion: Our study demonstrates inequity in neonatal survival that is related to ethnicity rather than family economy or education level of the mother and highlights the need to include the ethnic dimension in the efforts to reduce neonatal mortality.     

Trade-off between local access and safety considerations in childbirth: rural Tasmanian women's perspectives

Objectives: This study investigates: (i) Tasmanian rural women's preferences for different models of intrapartum care; (ii) their preferences for travel time to safe delivery; and (iii) factors which influence these preferences. Design: Mixed‐methods study using a survey questionnaire and semistructured interviews was adopted. A questionnaire explored women's preferences for different models of care and preferred travel time. Interviews were conducted to validate the survey results and provide insightful information on their preferences on the models of care. Women who have had rural childbirth experiences from six Tasmanian rural communities were invited to participate in the study. Results: Two hundred and ten women completed the questionnaire with a response rate of 35%. Twenty‐two follow‐up interviews were conducted. The survey found that women preferred to give birth in a hospital setting to homebirth despite having to travel for two hours. Midwifery‐led care with one hour travel time was the second preferred model of care. Women were willing to travel to access the regional hospital but within limit. Their preferences suggest that women have to trade‐off between local access and safety considerations. The interviews validate the survey results. Three main themes emerged from the interview data namely (i) safety; (ii) distance from hospital; and (iii) type of delivery. Their preferences were associated with their maternal care experiences in the past. Conclusion: In order to achieve the maternity services that are woman centred and respond to the needs and preferences of women, the service design and provision should take into account these women's preferences.     

Epidemic of invasive pneumococcal disease, western Canada, 2005-2009

In Canada before 2005, large outbreaks of pneumococcal disease, including invasive pneumococcal disease caused by serotype 5, were rare. Since then, an epidemic of serotype 5 invasive pneumococcal disease was reported: 52 cases during 2005, 393 during 2006, 457 during 2007, 104 during 2008, and 42 during in 2009. Of these 1,048 cases, 1,043 (99.5%) occurred in the western provinces of Canada. Median patient age was 41 years, and most (659 [59.3%]) patients were male. Most frequently representing serotype 5 cases (compared with a subset of persons with non-serotype 5 cases) were persons who were of First Nations heritage or homeless. Restriction fragment-length polymorphism typing indicated that the epidemic was caused by a single clone, which multilocus sequence typing identified as sequence type 289. Large pneumococcal epidemics might go unrecognized without surveillance programs to document fluctuations in serotype prevalence.     

Prevention and Control of Fish-borne Zoonotic Trematodes in Fish Nurseries, Vietnam

Worldwide, >18 million persons were infected with fish-borne zoonotic trematodes in 2002. To evaluate the effectiveness of interventions for reducing prevalence and intensity of fish-borne zoonotic trematode infections in juvenile fish, we compared transmission rates at nurseries in the Red River Delta, northern Vietnam. Rates were significantly lower for nurseries that reduced snail populations and trematode egg contamination in ponds than for nurseries that did not. These interventions can be used in the development of programs for sustained control of zoonotic trematodes in farmed fish.     

Salmonella enterica Serovar Agbeni, British Columbia, Canada, 2011

TO THE EDITOR: Infection with Salmonella enterica serovar Agbeni is rare. In Canada, it was reported 8 times during 2000-2010 and never in the province of British Columbia (2011 population?4.5 million) (Public Health Agency of Canada, unpub. data). In June 2011, an outbreak of S. enterica ser. Agbeni affecting 8 persons was identified in British Columbia; pulsed-field gel electrophoresis patterns for all isolates were identical. Although no specific source was identified, 2 features were noted: 1) diagnosis through urine specimens for 3 of 8 persons and 2) a longer than typical incubation period for Salmonella spp. infection.     

Design evaluation and optimisation in crossover pharmacokinetic studies analysed by nonlinear mixed effects models

Bioequivalence or interaction trials are commonly studied in crossover design and can be analysed by nonlinear mixed effects models as an alternative to noncompartmental approach. We propose an extension of the population Fisher information matrix in nonlinear mixed effects models to design crossover pharmacokinetic trials, using a linearisation of the model around the random effect expectation, including within-subject variability and discrete covariates fixed or changing between periods. We use the expected standard errors of treatment effect to compute the power for the Wald test of comparison or equivalence and the number of subjects needed for a given power. We perform various simulations mimicking crossover two-period trials to show the relevance of these developments. We then apply these developments to design a crossover pharmacokinetic study of amoxicillin in piglets and implement them in the new version 3.2 of the r function PFIM.     

Harm reduction and “Clean” community: can Viet Nam have both?

ABSTRACT: The findings of our research show that while police play multiple roles in the fight against drug-related crime, they often perceived their tasks - especially preventing and controlling drug use on the one hand, and supporting harm reduction on the other - as contradictory, and this creates tensions in their work and relations with their communities. Although they are leaders and implementers of harm reduction, not all police know about it, and some remain skeptical or perceive it as contradictory to their main task of fighting drugs. Methadone treatment is seen by some as in competition with their main task of coordinating conventional drug treatment in the rehabilitation center. The history of drug use and the evolution of discourses on drug use in Viet Nam have created these conflicting pressures on police, and thus created contradictory expectations and led to different views and attitudes of police regarding various harm reduction measures. This might aid understanding why, despite the comprehensive and progressive policies on HIV/AIDS and harm reduction in Viet Nam, it is not easy for police to actively and effectively support and be involved in harm reduction at the ground level. To promote the wider acceptance of harm reduction the concept of community safety must be expanded to include community health; harm reduction must be integrated into the "new society" movement; and laws and policies need further revision to reduce contradiction between current drug laws and HIV laws. Harm reduction guidelines for police and other actors need to be disseminated and supported, embodying better ways of working between sectors, and all sectors in the partnership require support for building capacity to contribute to the overall goal.
