Background: Exercise is a key component in treating childhood obesity. Group exercise sessions with a trained instructor are ideal, but most treatment programs cannot offer these often enough to meet physical activity guidelines. At-home options that provide a similar-intensity workout are needed. Objective: To determine if exercise videos are a feasible at-home option for obese youth to meet recommended physical activity guidelines for moderate-to-vigorous exercise. Methods: Obese youth attended a summer camp focused on weight management. Subjects wore accelerometers to assess physical activity levels at camp. During camp, all subjects completed four exercise activities: three separate exercise sessions led by exercise physiologists (EP), as well as an exercise video (EV). Each exercise session utilized a different format: high intensity interval training (HIIT), group games (GG) and yoga. The EV, created by the same EP, included aerobic exercise and yoga. Data was analyzed to determine intensity associated with each exercise session. Results: Data was obtained from 16 (50%) accelerometers (9 girls, 7 boys). There was no difference in sedentary (SED) minutes per hour between activities. HIIT and GG had more moderate-vigorous physical activity (MVPA) than yoga (p<0.0001 and p=0.01) and EV (p<0.0001 and p=0.01). There was no difference in MVPA between HIIT and GG. Conclusions: Obese children exercised at higher intensities during instructor-led HIIT and GG exercise sessions than yoga or EV sessions.

This study outlined the implementation and evaluation of one associative and two dissociative coping strategies on rowing ergometer performance. Participants were 9 novice varsity rowers who performed a 40-min ergometer workout in 10 separate experimental sessions. At each workout participants were requested to row as far as possible in 40 min. A multiple-baseline design was utilized, which after varying amounts of baseline permitted implementing an associative or dissociative strategy for each participant. These strategies included associative, dissociative-video, and dissociative-music. Results indicated that performance improved under all conditions for all participants but that the greatest gains were found in the associative condition.

Health authorities recommend digital tools for home-based sport and exercise routines to stay active and healthy during the COVID-19 pandemic. The study investigates the prevalence, duration, most popular activities, and social selectivity of home-based digital sport and its contribution to overall levels of sporting activity during the pandemic. It is based on cross-sectional survey data (n = 1508), representing the population >14 years living in Germany. Data collection took place in October 2020, using computer-assisted web interviewing. Results show that overall, 23% of respondents used digital media for sports activities at least one time during the COVID-19 pandemic. Numbers increased during the lockdown and decreased afterwards. People engaged in a variety of fitness workouts, most frequently practiced with the help of publicly accessible fitness videos from video-sharing platforms. Digital sports practitioners are younger, better educated, and financially better off. Females are overrepresented. Individuals engaged in digital sports achieved 30 min/week more sports activity during the pandemic compared to individuals solely involved in offline sports. Hence, home-based digital sports activities were a popular means to stay active, particularly in the period of the lockdown. Strong social disparities indicate that the possible health benefits of digital sports only reach out to particular population groups.

The aim of this research was to determine the features of a step workout technique which may be related to motor system overloading in step aerobics. Subjects participating in the research were instructors (n=15) and students (n=15) without any prior experience in step aerobics. Kinematic and kinetic data was collected with the use of the BTS SMART system comprised of 6 calibrated video cameras and two Kistler force plates. The subjects’ task was to perform basic steps. The following variables were analyzed: vertical, anteroposterior, and mediolateral ground reaction forces; foot flexion and abduction and adduction angles; knee joint flexion angle; and trunk flexion angle in the sagittal plane. The angle of a foot adduction recorded for the instructors was significantly smaller than that of the students. The knee joint angle while stepping up was significantly higher for the instructors compared to that for the students. Our research confirmed that foot dorsal flexion and adduction performed while stepping up increased load on the ankle joint. Both small and large angles of knee flexion while stepping up and down resulted in knee joint injuries. A small trunk flexion angle in the entire cycle of step workout shut down dorsal muscles, which stopped suppressing the load put on the spine.

Objectives: An office-based workup strategy for patients with laryngopharyngeal lesions suspicious for carcinoma is analyzed. The feasibility of office-based transnasal flexible endoscopic biopsies under local anesthesia and the impact on the diagnostic workup are evaluated. Methods: This study is a prospective analysis of patients with laryngeal, oropharyngeal, and hypopharyngeal lesions suspicious for carcinoma. One hundred eighty-eight participants were divided into 2 groups. The first group underwent an office-based biopsy procedure under local anesthesia using a flexible digital video laryngoscope with instrument channel (n = 53), and the second group underwent a biopsy procedure under general anesthesia using rigid laryngopharyngoscopy (n = 135). Results: Office-based flexible endoscopic biopsies were tolerated well, and there were no complications. These biopsies were 92.5% successful in acquiring a definitive diagnosis. Costs were reduced. Diagnostic workup time and time until start of therapy were reduced to 2 days and 27 days, respectively. Conclusion: Office-based biopsy under local anesthesia using flexible digital video laryngoscopy is safe, cost-effective, and successful in providing a histopathological diagnosis. It reduces the diagnostic workup time significantly in patients with laryngeal, oropharyngeal, and hypopharyngeal cancer, while also reducing the necessity to subsequently perform a rigid laryngopharyngoscopy under general anesthesia.

We present the design and evaluation of Astrojumper, an immersive virtual reality exergame developed to motivate players to engage in rigorous, full-body exercise. We performed a user study with 30 people between the ages of 6 and 50 who played the game for 15 min. Regardless of differences in age, gender, activity level, and video game experience, participants rated Astrojumper extremely positively and experienced a significant increase in heart rate after gameplay. Additionally, we found that participants' ratings of perceived workout intensity positively correlated with their level of motivation. Overall, our results demonstrate that Astrojumper effectively motivates both children and adults to exercise through immersive virtual reality technology and a simple, yet engaging, game design.

Cardiac papillary fibroelastoma is a rare cause of embolic events, especially seen in young patients. A 38-year-old woman with a transient ischemic attack underwent cardiac diagnostic workup. Transesophageal echocardiography and magnetic resonance imaging identified a tumor on the anterior leaflet of the mitral valve as the only potential source of embolization. Video-assisted minimally invasive resection of the tumor and reconstruction of the mitral valve were performed. Postoperative transthoracic echocardiography showed no residual tumor or mitral valve insufficiency. Histology identified a papillary fibroelastoma. The patient was discharged on the 9th postoperative day in good physical condition and without any postoperative limitations.

Abstract Purpose of Review The goal of this review is to provide a comprehensive understanding of the pathophysiology, clinical presentation, diagnostic workup, and clinical management of thoracic endometriosis (TE), as well as highlight our personal experience with TE workup and management. Recent Findings TE can present in a wide range of clinical manifestations. Without high clinical suspicion, diagnosis can be delayed. Since no specific laboratory testing is available, diagnosis is often based on careful history taking, imaging, and direct visualization of endometrial lesions through video-assisted thoracoscopic surgery (VATS). Medical thoracoscopy (MT) may also be a useful tool in the diagnostic workup of TE. Summary The diagnosis and management of TE require a multidisciplinary approach and a high index of clinical suspicion. While VATS remains the gold standard for diagnosis, we share our experience using MT to diagnose and manage a case of TE-related hemothorax.
