BACKGROUND: There is contradictory evidence on the association between health check-ups and future morbidity. Among the general population, those with high socioeconomic position participate more often in health check-ups. The main aims of this study were to analyse if attendance to health check-ups are socioeconomically patterned and affect sickness absence over a 10-year follow-up. METHODS: This register-based follow-up study included municipal employees of the City of Helsinki...

BACKGROUND: The Air Medical Prehospital Triage (AMPT) score was developed to identify injured patients who may benefit from scene helicopter emergency medical services (HEMS) transport. External validation using a different dataset is essential to ensure reliable performance. The study objective was to validate the effectiveness of the AMPT score to identify patients with a survival benefit from HEMS using the Pennsylvania Trauma Outcomes Study (PTOS) registry. METHODS: Patients age≥16years undergoing scene HEMS or ground EMS (GEMS) transport in the PTOS registry 2000-2013 were included...

OBJECTIVE: To analyze the trend of low birth weight (LBW) and its determinants in Brazilian state capitals between 1996 and 2011. We intended to determine which variables are associated with LBW during the period studied. METHODS: This is a cross-sectional study that used data from the National Information System of Live Births from 26 state capitals and Brasilia (the federal capital), divided into five geographical regions. The Average Annual Percentage of Change (AAPC) was used to assess the possible time trend in the low birth weight rates for considering all regions together and each region separately, according to each variable, and the Poisson regression was calculated in order to demonstrate time trends in low birth weight and the impact of variables (age and educational maternal level, antenatal visits, type of delivery, and gestational age) during the period...

BACKGROUND: Type 2 diabetes mellitus (T2DM) incidence is traditionally derived from cohort studies that are not always feasible, representative, or available. The present study estimates T2DM incidence in Fijian adults from T2DM prevalence estimates assembled from surveys of 25-64 year old adults conducted over 30 years (n = 14,288). METHODS: T2DM prevalence by five-year age group from five population-based risk factor surveys conducted over 1980-2011 were variously adjusted for urban-rural residency, ethnicity, and sex to previous censuses (1976, 1986, 1996, 2009) to improve representativeness...

BACKGROUND: Childhood cancer survivors can have a high burden of chronic conditions related to cancer treatment, some of which are debilitating or potentially life-threatening. Much remains to be learned about late effects in bone and soft tissue sarcoma survivors. PROCEDURES: The Utah Cancer Registry was used to identify survivors of bone (N = 71) and soft tissue sarcomas (N = 98) who were diagnosed at ages 0-20 years between 1973 and 2007 and were alive at least 5 years after diagnosis...

Increased risks of lung and bladder cancer have been observed in populations exposed to high levels of inorganic arsenic. However, studies at lower exposures (i.e., less than 100 μg/l in water) have shown inconsistent results. We therefore conducted an ecological analysis of the association between historical drinking water arsenic concentrations and lung and bladder cancer incidence in U.S. counties. We used drinking water arsenic concentrations measured by the U.S. Geological Survey and state agencies in the 1980s and 1990s as proxies for historical exposures in counties where public groundwater systems and private wells are important sources of drinking water...

PURPOSE: Folliular redox balance is likely to be important for embryo quality during in vitro fertilization (IVF), and the anti-oxidative high desity lipoprotein (HDL) particle is the sole lipoprotein measured in follicular fluid (FF). Therefore, we investigated FF HDL particle components as predictors of embryo quality during IVF. METHODS: Two research follicles collected from each participant were individually tracked, and 103 women having at least one developed embryo were included in the analysis...

The objective of this study was to evaluate the effectiveness of forward collision warning (FCW) alone, a low-speed autonomous emergency braking (AEB) system operational at speeds up to 19mph that does not warn the driver prior to braking, and FCW with AEB that operates at higher speeds in reducing front-to-rear crashes and injuries. Poisson regression was used to compare rates of police-reported crash involvements per insured vehicle year in 22 U.S. states during 2010-2014 between passenger vehicle models with FCW alone or with AEB and the same models where the optional systems were not purchased, controlling for other factors affecting crash risk...

The researchers conducted a communication training intervention for certified nursing assistants (CNAs). The intervention aimed at improving CNAs' therapeutic techniques for relating to agitated residents during care. This study focused on an in-depth evaluation of mealtime interactions using videos. Sixteen CNAs and 16 residents living with dementia from one long-term care facility were videotaped during mealtime interactions before and after a therapeutic communication training program. Mixed-effect Poisson regression revealed no effect of the intervention as a whole on residents' refusals, but the intervention did improve CNAs' communication...

High coverage is essential for an effective screening programme. Here we present screening barriers and facilitators among 1.3 million women aged 25-69years eligible for screening within the Norwegian Cervical Cancer Screening Program (NCCSP). We defined non-adherence as no screening test in 2008-2012. We divided adherent women into those screened spontaneously, and those who had a smear after receiving a reminder from the NCCSP. Explanatory variables were extracted from several nationwide registers, and modelled by modified Poisson regression...

Epidemiologic and clinical data suggest that Helicobacter pylori infection is a contributing factor in the progression of atherosclerosis. However, the specific cardiovascular disease risk factors associated with H. pylori remain unclear. We performed a cross-sectional study of 37,263 consecutive healthy subjects who underwent a routine health check-up. In multivariable log Poisson regression models adjusted for potential confounders, the associations of H. pylori seropositivity with higher LDL-C (relative risk [RR], 1...
