Purpose: This study explored one physical education teacher's engagement in an online professional learning community and her perceptions of its impact on her own feelings of isolation. Sense of community theory was used as a lens to explore the data. Method: Using a single instrumental case study design, the participant of this study was a female physical education teacher. The data were collected through semistructured interviews, public tweets (Twitter), and informal participant communication (Voxer). The data were analyzed using categorical aggregation, and codes with similar meanings were combined to develop themes. Results: Three themes were evident across data sources that represented her perceptions of participation in an online professional learning community: (a) taking initiative, (b) different support systems, and (c) stages of social media participation. Conclusion: Social media can provide a sense of community for physical education teachers, allowing them to feel less isolated.

ObjectivesExposure to 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD) has inconsistently been associated with a decreased sex ratio of the offspring (number of male births divided by total births). We conducted a study among men and women who were employed in a New Zealand phenoxy herbicide production plant between 1969 and 1984, to study their offspring sex ratio in relation to their back-calculated TCDD serum concentrations determined in 2007/2008.MethodsA total of 127 men and 21 women reported that 355 children were conceived after starting employment at the plant. The association between their lipid-standardised TCDD serum concentrations back-calculated to the time of their offspring's birth and the probability of a male birth was estimated through logistic regression, adjusting for the age of the exposed parent at birth, current body mass index and smoking.ResultsThe overall sex ratio was 0.55 (197 boys, 158 girls). For fathers with serum TCDD concentrations ≥20 pg/g lipid at time of birth, the sex ratio was 0.47 (OR 0.49; 95% CI 0.30 to 0.79). The probability of a male birth decreased with higher paternal serum TCDD at time of birth (

PurposeTo quantify serum concentrations of 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD) and dioxin-like compounds in former phenoxy herbicide production plant workers and firefighters, 20 years after 2,4,5-T production ceased.MethodsOf 1025 workers employed any time during 1969-1984, 430 were randomly selected and invited to take part in a morbidity survey and provide a blood sample; 244 (57%) participated. Firefighters stationed in close proximity of the plant and/or engaged in call-outs to the plant between 1962 and 1987 also participated (39 of 70 invited). Reported here are the serum concentrations of TCDD and other chlorinated dibenzo-dioxins, dibenzofurans, and polychlorinated biphenyls (PCBs). Determinants of the serum concentrations were assessed using linear regression.ResultsThe 60 men who had worked in the phenoxy/TCP production area had a mean TCDD serum concentration of 19.1 pg/g lipid, three times the mean concentration of the 141 men and 43 women employed in other parts of the plant (6.3 and 6.0 pg/g respectively), and more than 10 times the mean for the firefighters (1.6 pg/g). Duration of employment in phenoxy herbicide synthesis, maintenance work, and work as a boilerman, chemist, and packer were associated with increased serum concentrations of TCDD and 1,2,3,4,7-pentachlorodibenzo-p-dioxin (PeCDD). Employment as a boilerman was also associated with elevated serum concentrations of PCBs.ConclusionsOccupations in the plant associated with phenoxy herbicide synthesis had elevated levels of TCDD and PeCDD. Most other people working within the plant, and the local firefighters, had serum concentrations of dioxin-like compounds comparable to those of the general population.

On November 30, 2022, the emergence of a super-large artificial intelligence (AI) chatbot called ChatGPT (chat generative pre-trained transformer) astonished the world with its exceptional performance capabilities. ChatGPT is a trained AI chatbot developed by an American AI research laboratory called OpenAI. It provides users with a dialogueformat online chat that responds to and follows up on questions, admits mistakes, challenges incorrect premises, and rejects inappropriate requests. ChatGPT has evolved tremendously in just a few months (GPT-4 was released on March 14, 2023) to include multiple advanced features, such as image and infographic analysis, extended text processing, and safer and more accurate responses. Many experts, professionals, and scholars in various fields are looking at both the advantages and disadvantages of using this tool, and the field of kinesiology is no exception. Because technological advancement is inevitable, people working in a range of industries are considering how and to what extent they can incorporate ChatGPT and other tools that offer similar capabilities and features (e.g., Google Bard, Microsoft Bing, and Chatsonic) into their daily work. As in other fields of study, ChatGPT can be deployed to promote work efficiency for practitioners, learners, educators, and researchers within the field of kinesiology. Stakeholders should learn and stay updated with the latest version of ChatGPT to enhance overall performance in each subdiscipline of kinesiology while experimenting with its new features to obtain more accurate and productive responses. The purpose of this article is to discuss how ChatGPT can be used in the field of kinesiology, and more specifically in the areas of exercise science, physical activity and health promotion, physical education, and sport management, along with topics related to accuracy optimization, its use in higher education, challenges, concerns, ethical considerations, and future directions.

Background: Most studies assessing pathophysiological heterogeneity in asthma have been conducted in high-income countries (HICs), with little known about the prevalence and characteristics of different asthma inflammatory phenotypes in low-and middle-income countries (LMICs). This study assessed sputum inflammatory phenotypes in five centres, in Brazil, Ecuador, Uganda, New Zealand (NZ) and the United Kingdom (UK).Methods: We conducted a cross-sectional study of 998 asthmatics and 356 non-asthmatics in 2016-20. All centres studied children and adolescents (age range 8-20 years), except the UK centre which involved 26-27 year-olds. Information was collected using questionnaires, clinical characterization, blood and induced sputum.Results: Of 623 asthmatics with sputum results, 39% (243) were classified as eosinophilic or mixed granulocytic, i.e. eosinophilic asthma (EA). Adjusted for age and sex, with NZ as baseline, the UK showed similar odds of EA (odds ratio 1.04, 95% confidence interval 0.37-2.94) with lower odds in the LMICs: Brazil (0.73, 0.42-1.27), Ecuador (0.40, 0.24-0.66) and Uganda (0.62, 0.37-1.04). Despite the low prevalence of neutrophilic asthma in most centres, sputum neutrophilia was increased in asthmatics and non-asthmatics in Uganda.Conclusions: This is the first time that sputum induction has been used to compare asthma inflammatory phenotypes in HICs and LMICs. Most cases were non-eosinophilic, including in settings where corticosteroid use was low. A lower prevalence of EA was observed in the LMICs than in the HICs. This has major implications for asthma prevention and management, and suggests that novel prevention strategies and therapies specifically targeting non-eosinophilic asthma are required globally.

An imbalance in autonomic nervous system (ANS) activity may play a role in asthma, but it is unclear whether this is associated with specific pathophysiology. This study assessed ANS activity by measuring heart rate variability (HRV) in eosinophilic (EA) and non-eosinophilic asthma (NEA) and people without asthma. HRV, combined hypertonic saline challenge/sputum induction, exhaled nitric oxide (FeNO), skin prick tests to measure atopy, and spirometry tests were conducted in teenagers and young adults (14–21 years) with (n = 96) and without (n = 72) generally well-controlled asthma. HRV parameters associated with sympathetic and parasympathetic ANS branches were analyzed. EA and NEA were defined using a 2.5% sputum eosinophil cut-point. Airway hyperreactivity (AHR) was defined as ≥15% reduction in FEV1 following saline challenge. HRV parameters did not differ between asthmatics and non-asthmatics or EA and NEA. They were also not associated with markers of inflammation, lung function or atopy. However, increased absolute low frequency (LFµs2; representing increased sympathetic nervous system (SNS) activity) was found in asthmatics who used β-agonist medication compared to those who did not (median: 1611, IQR 892–3036 vs 754, 565–1592; p < 0.05) and increased normalized low frequency (LF nu) was found in those with AHR compared to without AHR (64, 48–71 vs 53, 43–66; p < 0.05). ANS activity (as measured using HRV analysis) is not associated with pathophysiology or inflammatory phenotype in young asthmatics with generally well-controlled asthma. However, enhanced SNS activity can be detected in asthmatics with AHR or who use β-agonist medication. [ABSTRACT FROM AUTHOR]
