Frontline Field Epidemiology Training Programs as a Strategy to Improve Disease Surveillance and Response.

Since 1980, Field Epidemiology Training Programs (FETPs) have trained highly qualified field epidemiologists to work for ministries of health (MOH) around the world. However, the 2013-2015 Ebola epidemic in West Africa, which primarily affected Guinea, Liberia, and Sierra Leone, demonstrated a lack of field epidemiologists at the local levels. Trained epidemiologists at these levels could have detected the Ebola outbreak earlier. In 2015, the US Centers for Disease Control and Prevention (CDC) launched FETP-Frontline, a 3-month field training program targeting local MOH staff in 24 countries to augment local public health capacity. As of December 2016, FETP-Frontline has trained 1,354 graduates in 24 countries. FETP-Frontline enhances global health security by training local public health staff to improve surveillance quality in their jurisdictions, which can be a valuable strategy to strengthen the capacity of countries to more rapidly detect, respond to, and contain public health emergencies at the source.

Brace prescription patterns in patients referred to orthopaedic clinics for adolescent idiopathic scoliosis (AIS).

Even if braces for scoliosis are broadly used, there are no data on the orthopaedic medical practice to evaluate the circumstances of brace prescription. This study aims at comparing scoliosis brace prescription patterns with generally recognized standards. A cross-sectional study was carried out in 2006-2007 on all confirmed AIS patients referred to a paediatric scoliosis clinic for a first visit. Agreement between the actual brace prescription patterns and standards for immediate prescription was analyzed, following the recommendations of the Quebec Scoliosis Network (QSN), as well as the Scoliosis Research Society (SRS) therapeutic inclusion criteria. In addition, chi-2 tests and logistic regression models were used to identify variables related to brace prescription. Amongst the 321 AIS patients, immediate brace treatment was recommended in 70 cases, for about 50% of concordance with the defined criteria. Variables describing the patients' maturity (age, Risser, onset of menses) and deformity magnitude (Cobb angle and rib hump), as well as the treating physician, were the main determinants of brace prescription. Despite the professional consensus on immediate bracing norms, under and over-prescription of brace were documented in this study. Better understanding of these patterns would require documentation of motives associated with prescription at the individual level.

Estimating the size of the population of persons who inject drugs in the island of Montréal, Canada, using a six-source capture-recapture model.

BACKGROUND: To plan and implement services to persons who inject drugs (PWID), knowing their number is essential. For the island of Montréal, Canada, the only estimate, of 11,700 PWID, was obtained in 1996 through a capture-recapture method. Thirteen years later, this study was undertaken to produce a new estimate. METHODS: PWID were defined as individuals aged 14-65 years, having injected recently and living on the island of Montréal. The study period was 07/01/2009 to 06/30/2010. An estimate was produced using a six-source capture-recapture log-linear regression method. The data sources were two epidemiological studies and four drug dependence treatment centres. Model selection was conducted in two steps, the first focusing on interactions between sources and the second, on age group and gender as covariates and as modulators of interactions. RESULTS: A total of 1480 PWID were identified in the six capture sources. They corresponded to 1132 different individuals. Based on the best-fitting model, which included age group and sex as covariates and six two-source interactions (some modulated by age), the estimated population was 3910 PWID (95% confidence intervals (CI): 3180-4900) which represents a prevalence of 2.8 (95% CI: 2.3-3.5) PWID per 1000 persons aged 14-65 years. CONCLUSIONS: The 2009-2010 estimate represents a two-third reduction compared to the one for 1996. The multisource capture-recapture method is useful to produce estimates of the size of the PWID population. It is of particular interest when conducted at regular intervals thus allowing for close monitoring of the injection phenomenon.

Comparative study of major depressive symptoms among pregnant women by employment status.

The objectives of our study were to compare the prevalence of major depressive symptoms between subgroups of pregnant women: working women, women who had stopped working, housewives and students; and to identify risk factors for major depressive symptoms during pregnancy. The CES-D scale (Center for Epidemiological Studies Depression scale) was used to measure major depressive symptoms (CES-D score ≥23) in 5337 pregnant women interviewed at 24-26 weeks of pregnancy. Multivariate logistic regression models were developed to identify risk factors associated with major depressive symptoms. Prevalence of major depressive symptoms was 11.9% (11.0-12.8%) for all pregnant women. Working women had the lowest proportion of major depressive symptoms [7.6% (6.6-8.7%); n = 2514] compared to housewives [19.1% (16.5-21.8%); n = 893], women who had stopped working [14.4% (12.7-16.1%); n = 1665], and students [14.3% (10.3-19.1%); n = 265]. After adjusting for major risk factors, the association between pregnant women's employment status and major depressive symptoms remained significant for women who had stopped working (OR: 1.61; 95% CI 1.26 to 2.04) and for housewives (OR: 1.46; 95% CI 1.10 to 1.94), but not for students (OR: 1.37; 95% CI 0.87 to 2.16). In multivariate analyses, low education, low social support outside of work, having experienced acute stressful events, lack of money for basic needs, experiencing marital strain, having a chronic health problem, country of birth, and smoking were significantly associated with major depressive symptoms. Health professionals should consider the employment status of pregnant women when they evaluate risk profiles. Prevention, detection and intervention measures are needed to reduce the prevalence of prenatal depression.

Preparation for discharge, maternal satisfaction, and newborn readmission for jaundice: comparing postpartum models of care.

BACKGROUND: Physiological jaundice generally appears between the third and fifth days of life. The danger of hyperbilirubinemia is therefore a major challenge when postpartum hospital stays are short, and part of the responsibility for screening for signs of jaundice is assumed by the mother. The objective of this study was to identify the model of postnatal continuity of care most likely to prepare mothers for discharge, to reduce newborn readmission for jaundice, and to enhance maternal satisfaction. METHODS: An epidemiological study was conducted in regions operating under 3 different models of postnatal continuity of care. Eligible mothers were those who had spent less than 60 hours in hospital after an uncomplicated vaginal delivery. Of this group, 70.8 percent participated in telephone interviews conducted 1 month after their deliveries (n=1,096). Newborns who had presented with signs of jaundice were identified through statements from their mothers. RESULTS: Of the participating newborns, 45.5 percent presented with signs of jaundice, and 3.2 percent were readmitted for jaundice during the first week of life. The follow-up procedures used in regions operating under a community-based model most closely followed the recommendations of health authorities and featured a high level of mothers' satisfaction. In the region operating under a mixed hospital model, mothers reported signs of jaundice significantly more often, and postdischarge services received by mothers were less effective at allaying their fears compared with other models. Phototherapy was offered in the home only in the region operating under a mixed ambulatory model, and no readmissions for jaundice were recorded in this region. CONCLUSIONS: An effective coordination between community-based perinatal services and hospital-linked home phototherapy in the form of an integrated network appears to be an essential condition for improved monitoring of newborns' health since it fosters a follow-up that is focused not only on jaundice but also on mothers' and newborns' needs while reducing the costs generated by newborn readmissions.
