RATIONALE: Drug abuse or dependence results in a series of social problems, including crime and traffic accidents. Spray inlet microwave plasma torch tandem mass spectrometry (MPT-MS/MS) was developed and used for the direct detection of such drugs in liquid solutions. METHODS: Drug sample solutions were directly sprayed into the flame of MPT by a sampling pump and the ions produced by Penning ionization and ion-molecule reactions were guided into a QTOF tandem mass spectrometer for mass analysis...

OBJECTIVE: Ensuring ready access to free drinking-water in schools is an important strategy for prevention of obesity and dental caries, and for improving student learning. Yet to date, there are no validated instruments to examine water access in schools. The present study aimed to develop and validate a survey of school administrators to examine school access to beverages, including water and sports drinks, and school and district-level water-related policies and practices. DESIGN: Survey validity was measured by comparing results of telephone surveys of school administrators with on-site observations of beverage access and reviews of school policy documents for any references to beverages...

A The incidence of exercise-associated hyponatremia (EAH) is higher in women than in men. We present three cases of a very mild post-race EAH in female winners of three 24-h ultra races in various weather conditions and disciplines with post-race plasma sodium [Na⁺] levels of 134 mM (Case 1), 133 mM (Case 2) and 134 mM (Case 3). Moreover, Case 1 and Case 2 showed elevated creatine kinase concentrations of >10,000 U/l with an absence of renal function abnormality. The common characteristics were female sex, veteran recreational category, long race experience in the particular sports discipline, excellent race performance, similar total weekly training hours and the presence of luteal phase of the menstrual cycle during the race...

We investigated the effects of fluid ingestion during exercise in different environments on the serum brain-derived neurotrophic factor and cognition among athletes. Ten collegiate male athletes (soccer, n = 5; rugby, n = 5) were enrolled, and they completed running tests in the following four conditions (60 min each): 1) thermoneutral temperature at 18°C (group 18); 2) high ambient temperature at 32°C without fluid ingestion (group 32); 3) high ambient temperature at 32°C with water ingestion (group 32+W); and 4) high ambient temperature at 32°C with sports drink ingestion (group 32+S)...

Oral electrolyte solutions are used widely for rehydration in diarrheal illness and to maintain hydration during vigorous exercise. In diarrheal illness, an oral rehydration solution (ORS) typically is preferred over intravenous fluids except for patients with severe dehydration. The preferred ORS is one similar to the glucose-containing reduced osmolarity World Health Organization ORS. There also are polymer-based solutions that use rice or wheat as the source of carbohydrates but these are not widely recommended...

Obesity is a global pandemic that brings about a myriad of health consequences. In the past, policies for combating obesity mainly focused on improving individual health and behavior, but nowadays some policies have changed and now concentrate on improving the built environment believing this can improve health through positive changes to health-related behaviors. We examined whether both individual and environmental factors were associated with body mass index in Seoul, the capital city of South Korea. Data from the 2011 and 2013 Community Health Surveys were used (n = 20,147 men and 25,300 women)...

OBJECTIVE: The purpose of this study was to get new information from several sources about the background factors of Finnish smokers, snuffers, and dual users. Profiles of young smokers and snuffers were investigated in association with restorative treatment need, oral hygiene, eating habits, physical activity, body mass index (BMI), psychological and socioeconomic factors. MATERIAL AND METHODS: The study group comprised 3420 conscripts. The data were collected from four different sources: a health examination including an oral health screening, a computer-based questionnaire for investigating individual background factors, a psychological test assessing cognitive skills, and the Cooper test...

INTRODUCTION AND AIMS: Alcohol misuse and harm are more prevalent amongst sports people than non-sports people. Few studies have trialled interventions to address alcohol misuse for this group. The study aimed to test the effectiveness of an intervention to reduce alcohol misuse and related harms amongst amateur sports people in Ireland. DESIGN AND METHODS: A controlled trial was conducted in two counties in Ireland. A random selection of sports clubs in one county received a 4 month multi-faceted intervention...

As a clinical condition, boredom is an emotional state, widespread among young people, characterized by unpleasant feelings, lack of motivation, and low physiological arousal in which the level of stimulation is perceived as unsatisfactorily low. Boredom is an important emotional state due to its spread among young people. Recent research has mainly studied the complex connection between boredom and leisure-time experiences, which may be involved in adolescents' risk-taking behaviors. The current study aims to investigate boredom proneness, conceived as a personality trait, in adolescents' free time, and its involvement in more extreme behaviors, such as binge drinking and addictive Internet use, which may represent ways to cope with the search for additional stimuli...

Energy balance-related behavior on schooldays and beliefs about school-based interventions may differ between students in different educational levels, sexes, and BMI (body mass index) categories. In Zwolle (the Netherlands), 1,084 adolescents (13-15 years) at 9 secondary schools completed a questionnaire. Overweight prevalence (boys 18.1%, girls 19.3%) increased with decreasing educational level, especially in boys. Girls reported healthier behavior than boys regarding daily consumption of fruit (35% vs. 29%), vegetables (58% vs...

Energy drinks comprise a multibillion dollar market focused on younger, active and competitive individuals. Marketing includes claims of improved alertness and performance. The purpose of this study was to assess power (W) and velocity (m·s) of a simulated, isolated forehand stroke (FHS) and a counter movement vertical jump (CVJ) before and after ingestion of a commercially available energy shot (ES) or a placebo (PL). Healthy college-aged male and female (N=36) volunteers were randomly placed in the ES or PL...

BACKGROUND: High food insecurity has been demonstrated in rural American Indian households, but little is known about American Indian families in urban settings or the association of food insecurity with diet for these families. The purpose of this study was to examine the prevalence of food insecurity in American Indian households by urban-rural status, correlates of food insecurity in these households, and the relationship between food insecurity and diet in these households. METHODS: Dyads consisting of an adult caregiver and a child (2-5 years old) from the same household in five urban and rural American Indian communities were included...

BACKGROUND: The risk factors for tear progression in symptomatic rotator cuff tears have not been clarified yet. It is important for orthopaedic surgeons to know the natural course of tear progression when nonoperative management is to be chosen. HYPOTHESIS: Tears in younger patients, high-activity patients, or heavy laborers would progress in size more than those in older patients, low-activity patients, or light laborers. STUDY DESIGN: Case-control study; Level of evidence, 3...

BACKGROUND: Caffeinated products are widely available to adolescents, and consumption of caffeine products-energy drinks and coffee in particular-is on the rise in this age group (Branum, Rossen, & Schoendorf, 2014). Yet, little is known about the psychosocial context of caffeine use. Previous studies on adolescent caffeine use have focused on caffeine's acute physiological effects, rather than the psychosocial contexts and beliefs regarding different types of caffeinated beverages (e...

Energy drinks are a fast-growing class of beverage containing high levels of caffeine and sugar. Advertising and marketing have been key to their growth in South Africa. This paper documents trends in energy drink consumption and energy drink advertising, and examines the relationship between exposure to energy drink advertising and consumption. Logistic regressions were estimated of categories of energy drink consumption on individual characteristics, as well as exposure to energy drink advertising. Exposure to advertising is measured by reported viewing of channels high in energy drink advertising...
