The Impact of Behavioral and Psychological Factors on Physical Fitness in Medical and Nursing Students.

Physical activity improves general health and quality of life. A stressful academic environment can increase both physical and mental health disruptions in medical and nursing students, negatively impacting physical activity and fitness. We explored the relationship between the fitness profiles of 202 medical and graduate nursing students with self-reported levels of general and emotional health to elucidate the role of the psychosocial factors involved in choosing to exercise.

Low-to-moderate intensity aerobic exercise training modulates irritable bowel syndrome through antioxidative and inflammatory mechanisms in women: Results of a randomized controlled trial.

Our aim was to explore the putative beneficial effects of low-to-moderate intensity exercise training program in patients with irritable bowel syndrome (IBS). This study evaluated the changes in blood oxidative stress status, inflammatory biomarkers and IBS severity symptoms following 24 weeks of moderate aerobic exercise in sedentary IBS patients. A total of 109 female volunteers (aged 18-41 yrs) who fulfilled Rome III criteria for the diagnosis of IBS were screened and 60 were randomized to exercise (EX, n = 30) and non-exercise (NON-EX, n = 30) groups.

A randomized controlled trial examining the effects of 16 weeks of moderate-to-intensive cycling and honey supplementation on lymphocyte oxidative DNA damage and cytokine changes in male road cyclists.

The aim of this study was to investigate whether honey supplementation (70g, ninety minutes before each training session) attenuates changes in lymphocyte counts, DNA damage, cytokines, antioxidative and peroxidative biomarkers following moderate-to-intensive exercise training in male road cyclists. Healthy nonprofessional cyclists (n=24, aged 17-26years) were randomly assigned to exercise+supplement (EX+S, n=12) and exercise (EX, n=12) groups for an experimental period of 16weeks. Moderate-to-intensive exercise training increased lymphocytes DNA damage, cytokines and peroxidative biomarkers as well as decreased antioxidative biomarkers in the EX group.

A randomized controlled study examining the effect of exercise on inflammatory cytokine levels in post-menopausal women.

Background: Elevated plasma levels of inflammatory cytokine are associated with body mass index, percent body fat and increased morbidity. Evidence suggests that higher levels of physical activity result in beneficial anti-inflammatory effects compared to a more sedentary lifestyle. Further, reproductive hormones are associated with inflammaotry cytokines.

Improving secondary prevention screening in clinical encounters using mhealth among prelicensure master's entry clinical nursing students.

Aims: To determine the feasibility and acceptability of a mHealth application among nursing students for health promotion and secondary prevention health recommendations for hospitalized adult patients.

Methods: A pretest-posttest design with a convenience sample of 169 prelicensure master's entry clinical nursing students in a large urban public university. Survey questions assessed intention to use, perceived usefulness, perceived ease of use, subjective norm, voluntariness, clinical area relevance, output quality, and result demonstrability of the United States Preventive Services Task Force (USPSTF) evidence-based practice guidelines via the mHealth application.

Walnuts improve semen quality in men consuming a Western-style diet: randomized control dietary intervention trial.

We tested the hypothesis that 75 g of whole-shelled walnuts/day added to the Western-style diet of healthy young men would beneficially affect semen quality. A randomized, parallel two-group dietary intervention trial with single-blind masking of outcome assessors was conducted with 117 healthy men, age 21-35 yr old, who routinely consumed a Western-style diet. The primary outcome was improvement in conventional semen parameters and sperm aneuploidy from baseline to 12 wk.

Reproductive hormones and interleukin-6 in serious leisure male athletes.

Lifestyles associated with different types and intensities of exercise result in improved health including positive changes in chronic low-grade inflammatory biomarkers. Alternatively, some forms of exercise adversely affect reproductive health of men, including changes in circulating reproductive hormones. To explore the associations between exercise intensity and circulating levels of reproductive hormones, and inflammatory analytes in serious leisure athletes (triathletes and cyclists) and recreational athletes.

Hypothalamic--pituitary-- adrenal axis dysregulation in women with irritable bowel syndrome in response to acute physical stress.

Irritable bowel syndrome (IBS) supports the concept of a dysregulated hypothalamic-pituitary-adrenal (HPA) axis. This study investigates the neuroendocrine and psychological responses to the acute physical stress of a lumbar puncture (LP) in women with diarrhea-predominant IBS by assessing central and peripheral HPA activity and affective measures. Blood samples have been collected at baseline and immediately post- and 1 hr following LP from 13 women with IBS and 13 controls.

The effect of life stress on symptoms of heartburn.

Objective: Psychosocial stressors have been associated with exacerbations of symptoms in functional and inflammatory disorders of the gastrointestinal tract. The present longitudinal study tests the general hypothesis that life stressors can exacerbate symptoms in patients with chronic heartburn.

Methods: Sixty subjects with current heartburn symptoms were recruited by community advertisement and assessed for presence of stressful life events retrospectively over the preceding 6 months and prospectively for 4 months.
