RESUMEN
BACKGROUND: The Field Epidemiology Training Program (FETP)-Frontline is a three-month in-service training aimed at improving surveillance officers' capacity to collect, analyze, and interpret surveillance data, and respond to health emergencies. We evaluated the effectiveness of the FETP-Frontline which was introduced in Ethiopia in 2016. METHODS: We conducted a comparative, randomized cross-sectional study to assess surveillance-related knowledge, skills, and performance among trained and untrained officers using a structured questionnaire and observation checklist. We compared the knowledge, skills, and performance scores of trained and untrained officers using the Fisher's Exact test, chi-square test, and t-test at p-value < 0.05 for statistical significance. RESULTS: We conducted the study among 74 trained and 76 untrained surveillance officers. About three-quarters of all participants were male, and the average age was 34 (± 8.6) years. Completeness and timeliness of surveillance reports were significantly higher among trained than untrained surveillance officers. The trained officers were more likely to have produced epidemiologic bulletins (55% vs 33%), conducted active surveillance six months before the survey (88% vs 72%), provided surveillance training (88% vs 65%), conducted strengths, weakness, opportunities, and threats (SWOT) analysis (55% vs 17%), and utilized Microsoft Excel to manage surveillance data (87% vs 47%). We also observed improved surveillance officers' perceived skills and knowledge, and the availability and quality of surveillance formats and reports among the trained group. CONCLUSIONS: FETP-Frontline trained surveillance officers demonstrated better knowledge, skills, and performance in most surveillance activities compared to the untrained officers. FETP-Frontline can address competency gaps among district surveillance officers in Ethiopia and other countries. Scaling up the program to cover unreached districts can enable achieving the human resource development core capacity requirement of the International Health Regulations 2005.

BACKGROUND: Field epidemiology training programs (FETPs) have trained field epidemiologists who strengthen global capacities for surveillance and response to public health threats. We describe how FETP residents and graduates have contributed to COVID-19 preparedness and response globally. METHODS: We conducted a cross-sectional survey of FETPs between March 13 and April 15, 2020 to understand how FETP residents or graduates were contributing to COVID-19 response activities. The survey tool was structured around the eight Pillars of the World Health Organization's (WHO) Strategic Preparedness and Response Plan for COVID-19. We used descriptive statistics to summarize quantitative results and content analysis for qualitative data. RESULTS: Among 88 invited programs, 65 (74%) responded and indicated that FETP residents and graduates have engaged in the COVID-19 response across all six WHO regions. Response efforts focused on country-level coordination (98%), surveillance, rapid response teams, case investigations (97%), activities at points of entry (92%), and risk communication and community engagement (82%). Descriptions of FETP contributions to COVID-19 preparedness and response are categorized into seven main themes: conducting epidemiological activities, managing logistics and coordination, leading risk communication efforts, providing guidance, supporting surveillance activities, training and developing the workforce, and holding leadership positions. CONCLUSIONS: Our findings demonstrate the value of FETPs in responding to public health threats like COVID-19. This program provides critical assistance to countries' COVID-19 response efforts but also enhances epidemiologic workforce capacity, public health emergency infrastructure and helps ensure global health security as prescribed in the WHO's International Health Regulations.

PURPOSE: Analyses of the Life Span Study cohort of atomic bomb survivors have shown a statistically significant sex difference in the excess risk of incident lung cancer due to radiation exposure, with the radiation-related excess relative risk per gray (ERR/Gy) for women approximately 4 times that for men, after accounting for active smoking. We sought to determine the extent to which this risk difference could be explained by adjustment for passive smoke exposure, which is a known risk factor for lung cancer that was not measured among Life Span Study participants, and which could be particularly influential among female never-smokers. MATERIALS AND METHODS: The Life Span Study includes survivors of the atomic bombings of Hiroshima and Nagasaki and city residents who were not in either city at the time of the bombings, matched to survivors on city, sex, and age. First primary lung cancers were identified from population-based cancer registries between 1958 and 2009. Data on active smoking were obtained from mailed surveys and in-person questionnaires (1965-1991). We calculated passive smoke exposure for female never-smokers by attributing smoking pack-years at various intensities (5-50%) based on smoking patterns among men, stratified by city, birth year, radiation dose, and lung cancer status. Poisson regression models with additive and multiplicative interactions between radiation dose and smoking were used to estimate sex-specific radiation-related excess relative risks for lung cancer. RESULTS: During the study period, 2,446 first primary lung cancers were identified among 105,444 study participants. On average, male smokers started smoking 19.5 cigarettes per day at 21.5 years old. Partially attributing male smoking patterns to female never-smokers-to approximate passive smoke exposure-yielded lower radiation-related ERR/Gy estimates for women under a multiplicative radiation-smoking interaction model, leading to a lower female-to-male ratio of ERR/Gy estimates; however, this difference was evident only at very high passive smoke intensities. Under an additive radiation-smoking interaction model, the results were unchanged. CONCLUSIONS: Our results are consistent with the possibility that failure to account for passive smoke might contribute, in small part, to the higher radiation risk estimates for lung cancer among women compared to men in the Life Span Study.

BACKGROUND: Breech presentation affects approximately 3% of women with singleton pregnancies. External cephalic version is a manual procedure that reorients a foetus to cephalic position in preparation for birth, reducing indications for caesarean birth. However, unsuccessful attempts are associated with some adverse health outcomes. Versions are successful in 17-86% of attempts. Temporal trends in version success and association between maternal height or prenatal care and version success are unknown. Few population-based studies and no recent investigations in the United States have evaluated predictive factors for version success. OBJECTIVES: This study aimed to estimate the proportion of successful version procedures in the United States and to evaluate factors associated with version success. METHODS: We used birth certificate and hospital administrative data. The study included all women who had a singleton birth in Washington State between 2003-2014 following a version procedure (total n=4981). Prevalence ratios and 95% confidence intervals were calculated using Poisson regression. FINDINGS: 57.2% of version attempts were successful. Primiparity (Prevalence Ratio:1.43; 95% Confidence Interval:1.29-1.60) and multiparity (Prevalence Ratio:1.68; 95% Confidence Interval:1.50-1.88) were associated with procedure success. Oligohydramnios was associated with lower version success (Prevalence Ratio:0.75; 95% Confidence Interval:0.57-1.00). Maternal height, pre-pregnancy weight, polyhydramnios, frequency of prenatal care, smoking, infant sex, and year of birth were not significantly associated with version outcome. CONCLUSION: We found that most version procedures are successful. This reinforces that procedures may be able to reduce the frequency of caesarean birth. These contemporary results can help women and clinicians make decisions with realistic estimates of success.
