Cumulative Trauma Disorder

A pilot population-based telephone survey was performed to obtain estimates of the number of people playing musical instruments and of the prevalence of hand, arm, and neck pain of musicians. Of the 954 respondents, 209 (21.9%, 95% confidence interval of 18.9-24.9%) indicated that they played musical instruments. Of those who played instruments, keyboards (44.8%, CI 35.6-54.0%) and guitar (28.1%, CI 20.8-35.8%) were by far the most commonly played instruments. Of those respondents who played instruments, 35.3% indicated that they played 5 hours or more a week, with 9.1% playing 20 hours or more. Overall, 29% (CI 21.4-37.0%) of all musicians indicated significant pain. The highest rates were among those who played 5-9 hours per week (48%), followed by 20 hours or more (42%), 0-4 hours (24%), and 10-19 hours (18%). The study indicates that playing a musical instrument may be second only to computer use in prevalence as a possible risk factor for cumulative trauma disorder, and that more extensive research is needed.

The purpose of this study was to determine the risk of submersion injury and drowning among children with epilepsy and to define further specific risk factors. In a population-based retrospective cohort study the authors identified and reviewed records of all 0- through 19-year-old residents of King County Washington, who suffered a submersion incident between 1974 and 1990. Children with epilepsy were compared with those without epilepsy with regard to age, sex, site of incident, supervision, outcome, and presence of preexisting handicap. Relative risks were determined using population-based estimates of epilepsy prevalence. Of 336 submersions, 21 (6%) occurred among children with epilepsy. Children with epilepsy were more likely to be greater than 5 years old (86% vs 47%) and more likely to submerge in a bathtub (38% vs 11%). The relative risk of submersion for children with epilepsy was 47 (95% confidence interval [CI] 22 to 100) in the bathtub and 18.7 (95% CI 9.8 to 35.6) in the pool. The relative risk of drowning for children with epilepsy was 96 (95% CI 33 to 275) in the bathtub and 23.4 (95% CI 7.1 to 77.1) in the pool. These data support an increased risk of submersion and drowning among children with epilepsy.

Background: Playing-related musculoskeletal disorders are the most frequent complaints among instrumental musicians. The aims of this study were: to assess the prevalence of musculoskeletal pain; to evaluate neck, shoulder, and lower back disability; and to determine the associated factors with the presence of musculoskeletal pain among musicians. Methods: A population-based, cross-sectional descriptive study was conducted. We selected Spaniard musicians over 16 years old who played a musical instrument for at least five hours per week. They answered the Spanish versions of the Standardised Nordic Questionnaire, the Oswestry Disability Index, Neck Disability Index and Shoulder Pain and Disability Index. Results: We found 94.8% of musicians presented at least one symptomatic region in the last 12 months, and 72.3% in the last seven days. Female musicians (OR 4.38, CI 2.11−9.12), musicians with overweight or obesity (OR 5.32, CI 2.18−12.97), and musicians who play more than 14 h per week (OR 3.86, CI 1.80−8.29)were shown to be a higher risk of suffering musculoskeletal pain. Conclusions: Musculoskeletal disorders symptoms are highly prevalent in musicians. The main risk factors related to musculoskeletal disorders symptoms were gender (being female), overweight, obesity, and spending playing more than 14 h a week practicing. This study highlights the need to provide strategies to prevent occupational disabilities among musicians. Further studies are needed to analyse the prevalence of pain in the musician using other sampling methods.

Abstract Background The current study aimed to estimate the prevalence of alcohol use identified as a risk factor during pregnancies by the antenatal care providers, resulting in live births in British Columbia (BC) and to examine associations between alcohol use, adverse neonatal outcomes, and pregnancy complications. Methods This population-based cross-sectional study utilized linked obstetrical and neonatal records within the BC Perinatal Data Registry (BCPDR), for deliveries that were discharged between January 1, 2015 and March 31, 2018. The main outcome measures were alcohol use identified as a risk factor during pregnancy, associated maternal characteristics, pregnancy complications, and adverse neonatal outcomes. Estimates for the period and fiscal year prevalence were calculated. Chi-square tests were used to compare adverse neonatal outcomes and pregnancy complications by alcohol use during pregnancy identified as a risk factor. Logistic regression was used to examine the association between alcohol use identified as a risk factor during pregnancy and adverse neonatal outcomes and pregnancy complications, after adjusting for identified risk factors. Results A total of 144,779 linked records within the BCPDR were examined. The period prevalence of alcohol use during pregnancy identified as a risk factor was estimated to be 1.1% and yearly prevalence was 1.1, 1.1, 1.3 and 0.9% from the 2014/2015 to 2017/2018 fiscal years, respectively. Alcohol use identified as a risk factor was associated with younger maternal age, fewer antenatal visits, being primiparous, a history of mental illness, substance use and smoking. Neonates with alcohol use during pregnancy identified as a risk factor had greater odds of being diagnosed with: “low birth weight (1000-2499g)” (ICD-10: P07.1; aOR = 1.25; 95% CI: 1.01, 1.53), “other respiration distress of newborn” (ICD-10: P22.8; aOR = 2.57; 95% CI: 1.52, 4.07), “neonatal difficulty in breastfeeding” (ICD-10: P92.5; aOR = 1.97; 95% CI: 1.27, 2.92) and “feeding problems, unspecified” (ICD-10: P92.9; aOR = 2.06; 95% CI: 1.31, 3.09). Conclusions The prevalence of alcohol use during pregnancy identified as a risk factor was comparable to previous estimates within the BCPDR. Identified prenatal alcohol exposure was associated with notable differences in maternal and neonatal characteristics and adverse neonatal outcomes. More consistent, thorough screening and prevention efforts targeting alcohol use in pregnancy are urgently needed in Canada.

Abstract Funding Acknowledgements Type of funding sources: Public grant(s) – National budget only. Main funding source(s): German Federal Ministry of Education & Research (BMBF) Introduction According to the WHO 17.9 million people die because of cardiovascular diseases (CVD) each year, being the 3rd leading cause of death worldwide. Low cardiorespiratory fitness (CRF) is an important risk factor for CVD. Recent research showed that long-chain unsaturated ceramides are associated with higher risk of cardiovascular events, thus identifying ceramides as a potential novel and independent risk factor. However, not all ceramides are equal. We previously showed beneficial effects of very-long-chain ceramides (i.e. C24:0 and C24:0/C16:0 ratio) with higher concentrations being inversely associated with all-cause mortality and CVD events. Purpose We would like to investigate, if ceramides mediated their effects on developing CVD by affecting CRF. Therefore, we explored the association of three specific ceramides (C16:0, C22:0 and C24:0) and their ratios with different parameters of CRF. Methods We used data of the population-based Study of Health in Pomerania (SHIP-1) from North Germany (N: 1,247/men: 583, median age: 50.8 years/women: 664, median age: 50.2 years). Ceramides and CRF were assessed by LC/MS assay and symptom-limited cardiopulmonary exercise testing, respectively. VO2peak, VO2@AT, Wmax and respective indexing per kg body weight were used as outcomes. We used sex-stratified, multiple adjusted linear regression models. Participants with asthma, chronic lung disease, LVEF < 40% and cancer were excluded. Results In men, a 1-unit higher C24:0/C16:0 ratio was associated with higher VO2peak/kg (0.199 ml/min/kg [95% CI: 0.032, 0.365], P = 0.019), Wmax (1.368 W [0.033, 2.404], P = 0.010) and Wmax/kg (0.018 W/kg [0.007, 0.029], P = 0.002). In addition, a 1 µg/ml higher C24:0 concentration was related to greater Wmax/kg (0.054 W/kg [0.009, 0.099], P = 0.018). In women, a 1-unit greater C24:0/C16:0 ratio was associated with greater VO2peak (8.603 ml/min [0.019, 17.013], P = 0.045), VO2peak/kg (0.186 ml/min/kg [0.054, 0.319], P = 0.006), VO2@AT/kg (0.136 ml/min/kg [0.040, 0.231], P = 0.005) as well as higher Wmax/kg (0.015 W/kg [0.004, 0.026], P = 0.007). Furthermore, a 1 µg/ml higher C16:0 concentration was related to lower Wmax (-55.447 W [-101.775, -9.119], P = 0.019) and Wmax/kg (-0.736 W/kg [-1.341, -0.130], P = 0.017). Conclusions We report sex-specific associations between ceramides and CRF. In women, C24:0/C16:0 ratio was associated with more CRF parameters than in men. Furthermore, the single species C16:0 was significantly associated with lower maximal power in women only, whereas in men the single species C24:0 was significantly associated with higher maximal power. The positive association of the C24:0/C16:0 ratio with maximal CRF capacity is in agreement with previous findings of beneficial effects on the risk for CVD events and mortality. Future studies should explore the reason for different sex-specific ceramide profiles and whether ceramides are causally mediating their effects on CVD through CRF.

Objectives: To study the incidence, risk factors, and outcomes of conduction and rhythm disorders in a population-based cohort of patients with systemic sclerosis versus nonsystemic sclerosis comparators. Methods: An incident cohort of patients with systemic sclerosis (1980–2016) from Olmsted County, MN, was compared to age- and sex-matched nonsystemic sclerosis subjects (1:2). Electrocardiograms, Holter electrocardiograms, and a need for cardiac interventions were reviewed to determine the occurrence of any conduction or rhythm abnormalities. Results: Seventy-eight incident systemic sclerosis cases and 156 comparators were identified (mean age 56 years, 91% female). The prevalence of any conduction disorder before systemic sclerosis diagnosis compared to nonsystemic sclerosis subjects was 15% versus 7% ( p = 0.06), and any rhythm disorder was 18% versus 13% ( p = 0.33). During a median follow-up of 10.5 years in patients with systemic sclerosis and 13.0 years in nonsystemic sclerosis comparators, conduction disorders developed in 25 patients with systemic sclerosis with cumulative incidence of 20.5% (95% confidence interval: 12.4%–34.1%) versus 28 nonsystemic sclerosis patients with cumulative incidence of 10.4% (95% confidence interval: 6.2%–17.4%) (hazard ratio: 2.57; 95% confidence interval: 1.48–4.45), while rhythm disorders developed in 27 patients with systemic sclerosis with cumulative incidence of 27.3% (95% confidence interval: 17.9%–41.6%) versus 43 nonsystemic sclerosis patients with cumulative incidence of 18.0% (95% confidence interval: 12.3%–26.4%) (hazard ratio: 1.62; 95% confidence interval: 1.00–2.64). Age, pulmonary hypertension, and smoking were identified as risk factors. Conclusion: Patients with systemic sclerosis have an increased risk of conduction and rhythm disorders both at disease onset and over time, compared to nonsystemic sclerosis patients. These findings warrant increased vigilance and screening for electrocardiogram abnormalities in systemic sclerosis patients with pulmonary hypertension.

This paper offers a series of characterizations of prototypical musical timbres, called Timbre Trait Profiles, for 34 musical instruments common in Western orchestras and wind ensembles. These profiles represent the results of a study in which 243 musician participants imagined the sounds of various instruments and used the 20-dimensional model of musical instrument timbre qualia proposed by Reymore and Huron (2020) to rate their auditory image of each instrument. The rating means are visualized through radar plots, which provide timbral-linguistic thumbprints, and are summarized through snapshot profiles, which catalog the six highest- and three lowest-rated descriptors. The Euclidean distances among instruments offer a quantitative operationalization of semantic distances; these distances are illustrated through hierarchical clustering and multidimensional scaling. Exploratory Factor Analysis is used to analyze the latent structure of the rating data. Finally, results are used to assess Reymore and Huron’s 20-dimensional timbre qualia model, suggesting that the model is highly reliable. It is anticipated that the Timbre Trait Profiles can be applied in future perceptual/cognitive research on timbre and orchestration, in music theoretical analysis for both close readings and corpus studies, and in orchestration pedagogy.

Objective The present study aimed to investigate the effect of functional mitral regurgitation (FMR) on recurrence of paroxysmal atrial fibrillation (PAF) in patients undergoing radiofrequency catheter ablation. Methods This prospective cohort study comprised 107 patients with PAF. The patients were divided into the FMR and non-FMR groups. FMR was assessed by Doppler echocardiography before index ablation. All patients initially underwent circumferential pulmonary vein isolation (CPVI) and were followed up for 12 months after ablation. PAF, atrial tachycardia, or atrial flutter served as the endpoint indicator. Results The median duration of PAF was 24 (3–60) months. Binary logistic univariate and multivariate analyses showed that FMR was not a risk factor for recurrence of catheter ablation for PAF (hazard ratio=0.758, 95% confidence interval: 0.191–3.004; hazard ratio=0.665, 95% confidence interval: 0.134–3.300, respectively). Kaplan–Meier analysis showed no significant difference in the recurrence rate between the groups. Fifteen (15/107, 14%) cases of PAF were triggered by the pulmonary vein. Three (3/107, 2.8%) cases of PAF were triggered by the superior vena cava. Conclusions FMR is not an independent risk factor for predicting recurrence of catheter ablation for PAF. FMR does not affect patients undergoing radiofrequency catheter ablation for PAF.
