Pneumomediastinum and pneumoretroperitoneum as a result of mephedrone intoxication – a case report.

Introduction: Presence of air in mediastinal space, retroperitoneal space or subcutaneously is a rare con- dition in majority caused by trauma of airway or gastrointestinal (GI) tract. Rarely can it occur as a conse- quence after drug usage.  Case Presentation: We report a non-traumatic occurrence of pneumomediastinum, pneumoretroperito- neum and subcutaneous emphysema in a 27 year-old male patient who had been inhaling mephedrone for 4 days. Patient was admitted to Department of General, Endocrine and Transplant Surgery, Medical University of Gdansk. CT scans of neck, chest and abdomen were performed with suspicion of perforation of GI tract or airways. Perforation was excluded by gastroscopic and bronchoscopic examinations. Patient was treated conservatively with fluids and antibiotic therapy because of no abnormalities besides free air in mentioned cavities. During 6 days of hospitalization patient made a steady recovery and was discharged in good condition.  Conclusions: The presence of pneumomediastinum, pneumoretroperitoneum and subcutaneous emphyse- ma associated with mephedrone inhalation has been rarely reported in the literature in the past. There are only a few cases describing such complications and medical management required. By reporting this case we would like to emphasize that mentioned symptoms and history of drug use might seem life-threatening, however, this condition may be self-limiting as well. Therefore, good general state can potentially be indi- cation for a watch-and-wait approach with no surgical intervention necessary. 

Assessment of the implementation of energy needs and the participation of macroelements in the diet of professional athletes and amateur athletes training at the gym

Introduction. In sport, a key role in achieving success is the right training unit combined with the rational nutrition. Both professional and amateur sports require the delivery of an increased amount of energy and nutrients compared to people not making physical efforts. The aim of the work was to assess the energy value and the level of consumption of basic nutrients among professional athletes and amateurs at the gym. Material and methods. The research was conducted among 30 athletes who were at a sports camp in the "Zawisza" center and 30 amateur athletes training at the "Jatomi Fitness Drukarnia" gym in Bydgoszcz. The average age of the respondents was 20 ± 10.9 years. The energy value of the diet and the supply of macroelements were assessed on the basis of a 24-hour interview. Results. Energy supply for athletes accounted for 84.8% of the recommended norm of energy demand (women: 82.5%, men: 88.6%). The energy value of food intake consumed by amateur athletes training at the gym covered 81.1% of their 24-hour energy expenditure (women: 74.1%, men: 88.0%). The proportion of macronutrients in the diet of men and women training athletics was a well-defined level of the recommended standard: protein 92.9% and 85.8%, fats 126.3% and 117.7% and carbohydrates 77.9% and 72.8%, while for amateur trainers: 146.8% and 107.8% protein, 102.4% and 90.7% fats and 71.9% and 63.9% carbohydrates. Conclusions. An important element is the need for nutrition education of athletes. Nutritional intervention may increase the dietary awareness of people performing physical activity and help in proper balance of the menu

Physical activity levels as a quantifier in police officers and cadets

Objectives: The aim of the present study was to determine the physical activity levels of active duty police officers and police academy cadets in different life domains and intensities. These parameters were treated as potential quantifiers that could be used when assessing individuals preparing for work as future police officers. Material and Methods: The study recruited 153 active police officers and 176 cadets attending a police academy and administered a diagnostic survey, the long-form version of the International Physical Activity Questionnaire, while in the statistical analysis the Student's t-test for independent groups was applied. Results: It was determined that police officers present high physical activity levels within the work domain, which are developed from initial training at a police academy and then throughout their police career. Conclusions: Such data are important in the light of the role police officers play in public safety as well as the prominence of physical activity within a particular profession and how it can be targeted and tailored to their needs

Exome sequencing to explore the possibility of predicting genetic susceptibility to the joint occurrence of polycystic ovary syndrome and Hashimoto’s thyroiditis

A large body of evidence indicates that women with polycystic ovary syndrome (PCOS) have a higher risk of developing Hashimoto’s thyroiditis (HT) than healthy individuals. Given the strong genetic impact on both diseases, common predisposing genetic factors are possibly involved but are not fully understood. Here, we performed whole-exome sequencing (WES) for 250 women with sporadic PCOS, HT, combined PCOS and HT (PCOS+HT), and healthy controls to explore the genetic background of the joint occurrence of PCOS and HT. Based on relevant comparative analyses, multivariate logistic regression prediction modeling, and the most informative feature selection using the Monte Carlo feature selection and interdependency discovery algorithm, 77 variants were selected for further validation by TaqMan genotyping in a group of 533 patients. In the allele frequency test, variants in RAB6A, GBP3, and FNDC7 genes were found to significantly (padjusted < 0.05) differentiated the PCOS+HT and PCOS groups, variant in HIF3A differentiated the PCOS+HT and HT groups, whereas variants in CDK20 and CCDC71 differentiated the PCOS+HT and both single disorder groups. TaqMan genotyping data were used to create final prediction models, which differentiated between PCOS+HT and PCOS or HT with a prediction accuracy of AUC = 0.78. Using a 70% cutoff of the prediction score improved the model parameters, increasing the AUC value to 0.87. In summary, we demonstrated the polygenic burden of both PCOS and HT, and many common and intersecting signaling pathways and biological processes whose disorders mutually predispose patients to the development of both diseases

Epidemiology of physical activity in adult Polish population in the second decade of the 21st century. Results of the NATPOL 2011 study

Objectives: The aim of the study was to assess physical activity (PA) level in a representative sample of Polish adults.Materials and Methods: A cross-sectional analysis was performed among 2413 randomly selected individuals (51.5% women) aged 18-79 years, who participated in the Nationwide Study of Occurrence of Risk Factors of Cardiovascular Diseases NATPOL 2011 (March-July 2011). The study procedures consisted of a questionnaire as well as of anthropometric, blood pressure and biochemical measurements. Leisure-time, occupational and commuting PA were assessed by the use of a questionnaire interview. Results: About 48.2% of adults do exercise for at least 30 minutes on most days of a week. About 11% of the respondents declare a sedentary lifestyle. About 26.5% of working population report hard physical work, while sedentary work is reported by 47.6% of the employed participants. Active commuting is declared by 27.3% of working/studying population. About 47.2%, 36.6%, and 15.3% spend 30 min per day, respectively, on this kind of PA. Conclusions: PA level of more than half of Polish adults is still not satisfactory. Promotion of an active lifestyle should concern mainly leisure-time and commuting PA with paying special attention to substantial differences in various socio-demographic groups

Volunteer satisfaction in sports clubs: A multilevel analysis in 10 European countries

Regular voluntary engagement is a basic resource for sports clubs that may also promote social cohesion and active citizenship. The satisfaction of volunteers is an imperative factor in this engagement, and the purpose of this article is to explore individual and organizational determinants of volunteer satisfaction in sports clubs. Theoretically, our study builds on the actor-theory concepts where volunteer satisfaction depends on subjective evaluations of expectations and experiences in a sports club (‘logic of situation’), so that positive evaluations lead to higher satisfaction and, hopefully, retention of volunteers. This research uses a sample of 8131 volunteers from 642 sports clubs in 10 European countries, and is the first analysis to combine determinants at the level of the club and the volunteer (multilevel). Results show that the most important determinants of satisfaction are the conditions of volunteering (recognition, support, leadership and material incentives) and the workload of volunteers. Surprisingly, club characteristics, size or having paid staff are not significant determinants of volunteer satisfaction. The results of this analysis can assist more effective volunteer management in sports clubs that are facing challenges of individualization and professionalization
