Introduction: Military prehospital and en route care (ERC) directly impacts patient morbidity and mortality. Provider knowledge and skills are critical variables in the effectiveness of ERC. No Navy doctrine defines provider choice for patient transport or requires standardized provider training. Frequently, Search and Rescue Medical Technicians (SMTs) and Navy Nurses (ERC RNs) are tasked with this mission though physicians have also been used. Navy ERC provider training varies greatly by professional role...

Intermittent fasting (IF) and high intensity interval training (HIIT) are effective lifestyle interventions for improving body composition and overall health. However, the long-term effects of IF and potential synergistic effects of combining IF with exercise are unclear. The purpose of the study was to investigate the long-term effects of IF, with or without HIIT, on body composition and markers of metabolic health in diet-induced obese mice. In a randosmised, controlled design, 8-week-old C57BL/6 mice (males ( n = 39) and females ( n = 49)) were fed a high fat (HF) and sugar (S) water diet (30% ( w / v )) for 24-weeks but were separated into five groups at 12-weeks: (1) 'obese' baseline control (OBC); (2) no intervention (CON); (3) intermittent fasting (IF); (4) high intensity intermittent exercise (HIIT) and (5) combination of dietary and exercise intervention (IF + HIIT)...

Rates of short interval pregnancies resulting in unintended pregnancies remain high in the United States and contribute to adverse reproductive health outcomes. Long-acting reversible contraception (LARC) methods have annual failure rates of less than 1% compared with 9% for oral contraceptive pills, and are an effective strategy to reduce unintended pregnancies. To increase access to LARCs in the immediate postpartum period, several State Medicaid programs, including those in Iowa (IA) and Louisiana (LA), recently established reimbursement policies to remove the barriers to reimbursement of immediate postpartum LARC insertion...

In Canada, over 40% of invasive cervical cancers occur among women who have never been screened. Although 12% of Canadian women have never been screened, this number can be as high as 43% among certain social groups. Little is published on factors associated with screening uptake and inequalities among women residing in Quebec. Four waves of the Canadian Community Health Survey (2003, 2005, 2008, 2012, N = 6393) were utilized to assess lifetime screening and screening in the previous 3 years among women residing in Montreal...

BACKGROUND AND AIMS: Accurate optical diagnosis of diminutive polyps would allow implementing a resect and discard strategy. We evaluated the learning curve of a single training session followed by self-education in subjects with no endoscopic experience. METHODS: Learning curves were evaluated in 38 subjects employing learning curve-cumulative summation (LC-CUSUM) tests, with each participant attending one training session regarding narrow band imaging and optical diagnosis and then individually assessing 100 lesions, receiving feedback after each diagnosis...

BACKGROUND: Menopause is associated with fatty liver, glucose dysregulation, increased body fat, and impaired bone quality. Previously, it was demonstrated that single sessions of high-intensity interval exercise (HIIE) are more effective than distance- and duration-matched continuous exercise (CE) on altering hepatic triglyceride (TG) metabolism and very-low density lipoprotein-TG (VLDL-TG) secretion. METHODS: Six weeks training using these modalities was examined for effects on hepatic TG metabolism/secretion, glucose tolerance, body composition, and bone mineral density (BMD) in ovariectomized (OVX) and sham-operated (SHAM) mice...

AIMS: Different modes of physical activity provide cerebrovascular protection against thromboembolic events. Based on recent reports high intensity exercise protocols appear to raise cerebral VEGF levels leading to efficient cerebral angiogenesis. The present study aims to address if moderate continuous training (MCT) and high intensity interval training (HIT) differ in preconditioning against ischemic stroke. METHODS: Wistar rats were subjected to HIT or MCT for 8 weeks before transient middle cerebral artery occlusion (tMCAO) surgery...

Using guidance from the reach, efficacy, adoption, implementation, and maintenance evaluation framework, we aimed to qualitatively evaluate the participant experiences of a workplace high-intensity interval training (HIIT) intervention. Twelve previously insufficiently active individuals (four males and eight females) were interviewed once as part of three focus groups. Perceptions of program satisfaction, barriers to and facilitators of adherence, and persistence to exercise were explored. HIIT initiates interest because of its novelty, provides a sense of accomplishment, and overcomes the barriers of perceived lack of time...

Purpose The current TNM (Tumor Node Metastasis) staging system is inadequate at identifying high-risk colorectal cancer (CRC) patients. Using a systematic and comprehensive-biomarker discovery and validation approach, we aimed to identify a miRNA-recurrence classifier (MRC) that can improve upon the current TNM-staging as well as superior to currently offered molecular assays. Experimental Design Three independent genome-wide miRNA-expression profiling datasets were used for biomarker discovery (N=158) and in-silico validation (N=109 and N=40) to identify a miRNA signature for predicting tumor recurrence in CRC patients...

The growing prominence of community-based participatory research (CBPR) presents as an opportunity to improve tobacco-related intervention efforts. CBPR collaborations for tobacco/health, however, typically engage only adults, thus affording only a partial understanding of community context as related to tobacco. This is problematic given evidence around age of tobacco use initiation and the influence of local tobacco environments on youth. The CEASE and Resist youth photovoice project was developed as part of the Communities Engaged and Advocating for a Smoke-free Environment (CEASE) CBPR collaboration in Southwest Baltimore...

Introduction: The US Marines operate the Jungle Warfare Training Center (JWTC) in Northern Okinawa, where leptospirosis is endemic. The JWTC endurance course involves prolonged fresh and stagnant water exposures in a simulated jungle warfare environment. Since a leptospirosis outbreak in 1987, JWTC has required prophylactic use of doxycycline at 200 mg weekly during exposure to the endurance course. This policy is based on a 1982 study in a similar environment in Panama. In August and September of 2014, an outbreak of leptospirosis occurred among 81 Marines training at JWTC...

Although High-intensity interval training (HIIT) has shown its effectiveness in improving body composition, cardio-respiratory fitness and lipid profile in obese adults, evidences remain limited in overweight/obese youth. This study was conducted to investigate the effect of a 12-week HIIT program without caloric restriction on body composition and lipid profile among young overweight/obese men. Twenty healthy obese youth were randomly allocated into two groups; experimental group (HIIT) and control group. The HIIT program consisted in 3 exercises sessions per week (30 sec of work at 100% maximal aerobic velocity [MAV]) interspersed by 30 sec of active recovery at 50% MAV, starting by 15 repetitions to reach 27 by the end of the program...
