Abstract

Cross-sectional, analytical study that examined the link between sleep quality (SQ) and health-related quality of life (HRQOL) in young athletes in a sports competition. SQ was measured through the Pittsburgh Sleep Quality Index (PSQI), and HRQOL through the SF36 v2 (SF36v2) short-form health survey in 71 young athletes (39 men; mean age 16.9, SD = 1.2 years; mean 6.5, SD = 3.2 years in sports and mean 10.8, SD = 3.3 hours of weekly training) on the day prior to a competition. When comparing the athletes according to SQ (poor SQ > 5 PSQI), significant differences were found (p < .05) in HRQOL in the domains bodily pain, general health, vitality, social function, emotional role and mental health, but not in the domains bodily function and physical role. Our results suggest poor SQ is associated with a worse perception of HRQOL in young athletes in competition., Estudio analítico transversal que examinó el vínculo entre la calidad del sueño (SQ) y la calidad de vida relacionada con la salud (HRQOL) en jóvenes atletas en una competencia deportiva. SQ se midió a través del índice de calidad del sueño de Pittsburgh (PSQI) y HRQOL a través de la encuesta de salud de formato corto SF36 v2 (SF36v2) en 71 atletas jóvenes (39 hombres; edad media 16,9, SD = 1,2 años; promedio 6,5, SD 3,2 años de práctica deportiva; y promedio 10,8, SD = 3,3 horas de entrenamiento semanal) el día anterior a una competición. Al comparar los atletas según SQ (SQ deficiente > 5 PSQI), fueron encontradas diferencias significativas (p < ,05) en la HRQOL en los dominios dolor corporal, salud general, vitalidad, función social, rol emocional y salud mental, pero no en los dominios función corporal y rol físico. Nuestros resultados sugieren que un SQ deficiente se asocia con una peor percepción de la HRQOL en atletas jóvenes en competencia.

Abstract

Armed service recruits are faced with many stressors, including a strenuous training regimen that may have an impact on their physiological functioning. The Cardio Stress Index (CSI) is a noninvasive marker of the stress that the heart is experiencing. The aim of the study was to test the physiological impact of 20 weeks of intense training of armed service recruits, using CSI as a noninvasive biomarker of cardiac stress. Armed service recruits are faced with many stressors, including a strenuous training regimen that may have an impact on their physiological functioning. The CSI is a noninvasive marker of the stress that the heart is experiencing. The calculation of the CSI is based on the duration of vascular excitation (QRS duration), heart rate, heart rhythm and standard deviation of the duration of time between each successive cardiac cycle (RR-interval). The aim of the present study was to test the physiological impact of 20 weeks of strenuous training of armed service recruits, using CSI as a noninvasive biomarker of cardiac stress. Experiments were conducted at three points in time (weeks 1, 12, 20) during the basic military training of armed service recruits (n = 202, males = 115, females = 87), aged between 18 and 24 years. Variables measured include: Resting CSI, heart rate and blood pressure. Data analysis was performed, using paired t-tests for pairwise comparisons of week 1 (baseline) with week 12; week 12 with week 20; and week 1 with week 20. The average CSI and heart rate remained within normal values for male participants on all three testing occasions. However, baseline readings for females were significantly higher during week 1. There was an overall decrease in the CSI in the 20 week time frame. From this study it seems as if the CSI measurement is a noninvasive method to establish the effects of training on the health of the heart. [ABSTRACT FROM AUTHOR]

Abstract

Background: To derive a list of opportunistic infections (OI) through the analysis of the juvenile idiopathic arthritis (JIA) patients in the Pharmachild registry by an independent Safety Adjudication Committee (SAC). Methods: The SAC (3 pediatric rheumatologists and 2 pediatric infectious disease specialists) elaborated and approved by consensus a provisional list of OI for use in JIA. Through a 5 step-procedure, all the severe and serious infections, classified as per MedDRA dictionary and retrieved in the Pharmachild registry, were evaluated by the SAC by answering six questions and adjudicated with the agreement of 3/5 specialists. A final evidence-based list of OI resulted by matching the adjudicated infections with the provisional list of OI. Results: A total of 772 infectious events in 572 eligible patients, of which 335 serious/severe/very severe non-OI and 437 OI (any intensity/severity), according to the provisional list, were retrieved. Six hundred eighty-two of 772 (88.3%) were adjudicated as infections, of them 603/682 (88.4%) as common and 119/682 (17.4%) as OI by the SAC. Matching these 119 opportunistic events with the provisional list, 106 were confirmed by the SAC as OI, and among them infections by herpes viruses were the most frequent (68%), followed by tuberculosis (27.4%). The remaining events were divided in the groups of non-OI and possible/patient and/or pathogen-related OI. Conclusions: We found a significant number of OI in JIA patients on immunosuppressive therapy. The proposed list of OI, created by consensus and validated in the Pharmachild cohort, could facilitate comparison among future pharmacovigilance studies. © The Author(s). 2020 Open Access This article is licensed under a Creative Commons Attribution 4.0 International License, which permits use, sharing, adaptation, distribution and reproduction in any medium or format, as long as you give appropriate credit to the original author(s) and the source, provide a link to the Creative Commons licence, and indicate if changes were made.

Abstract

Background: Chronic exertional compartment syndrome (CECS) of the forearm is a rare but important cause of morbidity amongst athletes involved in strenuous upper limb activities. The diagnosis remains challenging due to the absence of objective, reproducible diagnostic studies., Objectives: To assess and quantify signal intensity (SI) changes of involved muscles in patients with CECS of the forearm compared to healthy control subjects competing in similar sporting disciplines. Also, to objectively measure MRI SIs within muscle compartments when using a pre- and post-exercise regime and calculating a signal intensity ratio (SIR) between post- and pre-exercise studies., Method: The study retrospectively examined MRI scans of patients treated for CECS of the forearm and compared these to the MRI scans of asymptomatic high-level rowers. A specific, reproducible pre- and post-exercise MRI scanning protocol was utilised in both patient and control subjects between 2011 and 2020. Signal intensities were evaluated pre- and post-exercise in involved muscle groups and ratios were calculated., Results: A total of 86 SIs were measured (43 pre- and 43 post-exercise) in nine study participants (five patients and four controls). After post:pre-exercise comparisons, a statistically significant difference was found between control and patient groups ( p = 0.0010). The extensor carpi radialis, flexor digitorum profundus and flexor digitorum superficialis muscles were most commonly involved., Conclusion: This study confirms that significant SI changes are apparent in patients with CECS of the forearm when making use of a standardised pre- and post-exercise MRI protocol. Furthermore, SIR may be used to accurately diagnose CECS of the forearm., Competing Interests: The authors declare that they have no financial or personal relationships that may have inappropriately influenced them in writing this article., (© 2021.
