RESUMO
OBJECTIVE: Investigate the prevalence of hearing protection (HP) use and behavioral motivations and barriers among adults attending music venues. STUDY DESIGN: Cross-sectional online survey study. SETTING: Noise exposure levels at popular social music venues often exceed national guidelines. METHODS: Surveys were distributed on online music communities. Respondents (n = 2352) were asked about demographics, HP use at music venues, knowledge about noise exposure impact, and perceptions of HP use. Data were characterized through descriptive statistics. Multivariable regression analysis explored differences in knowledge and perception between HP users and nonusers. RESULTS: In this cohort (mean age 29 ± 7 years, 61% male), HP users were significantly more aware of the impact of music venues on hearing (P < .01), believed their hearing ability had decreased after attending music venues (P < 0.01), and believed HP could protect from hearing loss (P < .01) than non-HP users. HP nonusers most frequently cited never considering HP (14.45%) and apathy about it affecting music quality (12.71%). Common sources of HP information were recommended by a friend/peer. Multivariable regression analysis accounting for demographics, medical history, and attendance characteristics found belief that HP use at music venues could protect from hearing loss (ß = 0.64, 95% confidence interval [CI] = [0.49-0.78]) and HP use (ß = 1.73, 95% CI = [1.47-1.98]) were significantly associated with increased subjective enjoyment while wearing HP. CONCLUSION: HP users and nonusers have significantly different perceptions of HP use and its impact. Our findings have implications for understanding motivations and barriers related to HP use and developing strategies to promote HP use at music venues.

PURPOSE: The purpose of this study was to measure the harms-related reporting among randomized controlled trials (RCTs) cited as supporting evidence for the American Academy of Orthopaedic Surgeons clinical practice guidelines regarding the management of distal radius fractures. METHODS: We adhered to the guidance for reporting metaresearch and the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines throughout the course of this investigation. We used the American Academy of Orthopaedic Surgeons clinical practice guidelines for distal radius fractures available on Orthoguidelines.org. A linear regression analysis was conducted to model the relationship between the year of publication and the total Consolidated Standards of Reporting Trials percentage adherence over time. RESULTS: Thirty-five RCTs were included in the final sample. The average number of Consolidated Standards of Reporting Trials Extension for Harms items adequately reported across all included RCTs was 9.2 (9.2/18, 50.9%). None of the included trials adequately reported all 18 items. Ten items had a compliance of more than 50% (10/18, 55.6%), 4 items had a compliance of 20%-50% (4/18, 22.2%), and 4 items had a compliance of less than 20% (4/18, 22.2%). The results of the linear regression model showed no significant improvement in Consolidated Standards of Reporting Trials Harms reporting over time. CONCLUSIONS: Adverse events are incompletely reported among RCTs cited as supporting evidence for American Academy of Orthopaedic Surgeons clinical practice guidelines for the management of distal radius fractures. CLINICAL RELEVANCE: Given our findings, specific attention should be paid to improving the standardization of the classification of adverse events to facilitate ease in the reporting process.
RESUMO
CD19 CAR T-cell immunotherapy is a breakthrough treatment for B cell malignancies, but relapse and lack of response remain a challenge. The bone marrow microenvironment is a key factor in therapy resistance, however, little research has been reported concerning the relationship between transcriptomic profile of bone marrow prior to lymphodepleting preconditioning and clinical response following CD19 CAR T-cell therapy. Here, we applied comprehensive bioinformatic methods (PCA, GO, GSEA, GSVA, PAM-tools) to identify clinical CD19 CAR T-cell remission-related genomic signatures. In patients achieving a complete response (CR) transcriptomic profiles of bone marrow prior to lymphodepletion showed genes mainly involved in T cell activation. The bone marrow of CR patients also showed a higher activity in early T cell function, chemokine, and interleukin signaling pathways. However, non-responding patients showed higher activity in cell cycle checkpoint pathways. In addition, a 14-gene signature was identified as a remission-marker. Our study indicated the indexes of the bone marrow microenvironment have a close relationship with clinical remission. Enhancing T cell activation pathways (chemokine, interleukin, etc.) in the bone marrow before CAR T-cell infusion may create a pro-inflammatory environment which improves the efficacy of CAR T-cell therapy.
