IntroductionYouTube is the most popular video-based source of information on the Internet. It is accessed by over 1 billion users, which approximates to almost one-third of all Internet users. Orthopaedic video content published on YouTube is not screened and does not go through an editorial process, and most videos do not have information about authorship or appropriate references. Users who do not have the knowledge to assess the accuracy and reliability of the source may be misinformed about their medical condition. Previous studies have evaluated the quality of YouTube content for information in orthopaedics such as meniscus, kyphosis, and anterior cruciate ligament (ACL), but the quality of frozen shoulder videos on YouTube has not been investigated. The purpose of this study is to evaluate the quality and educational value of YouTube videos concerning adhesive capsulitis. MethodsA YouTube search was performed using the term "frozen shoulder." Videos were excluded if they had no audio, were in a language other than English, or were longer than 10 minutes. A total of 70 videos were screened, and the first 50 videos that met the inclusion criteria were evaluated by three observers. Six video characteristics were extracted, and videos were categorized by source and content. Quality and educational value were assessed using the DISCERN (score range, 0-5), Global Quality score (GQS; score range, 0-4), and a Frozen Shoulder-Specific Score (FSSS; score range, 0-16). ResultsThe mean video duration was 242.46 ± 164.32 seconds. The mean number of views was 137,494 ± 262,756 and the total view count across 50 videos was 6,874,706. The mean DISCERN, GQS, and FSSS scores were 2.72 ± 0.85, 2.37 ± 0.895, and 4.42 ± 3.15, respectively. The video sources were primarily from non-physician healthcare professionals (32%), and most of the video content was focused on disease-specific information (50%). Significant between-group effects were observed for the DISCERN score and video source (P = .005), with videos from academic sources having the highest mean DISCERN score. DISCERN scores also differed significantly based on video content (P = .007), with disease content having the highest DISCERN score. Both GQS and FSSS scores differed significantly based on video content (both P < .001) but did not differ significantly based on the video source. ConclusionsInformation about frozen shoulder on YouTube is low quality and has limited educational value. Thus, providers for orthopaedic conditions should warn their patients and provide better alternatives for education.
Water vapor thermal therapy (Rezum) is a novel, minimally invasive surgical technology used to treat lower urinary tract symptoms (LUTS) secondary to benign prostatic hyperplasia (BPH). The objective of this systematic review is to evaluate the latest efficacy and safety profile of Rezum in patients with LUTS secondary to BPH. PubMed/MEDLINE and the Cochrane Library databases were systematically searched, in accordance with the PRISMA statement, for relevant articles in the English language till 1 August 2021. Randomized and nonrandomized studies that evaluated urinary outcomes and/or adverse events were deemed eligible. Nineteen studies (N = 1942), published in 25 articles, were included. International Prostate Symptom Score (IPSS), quality of life (QoL), and maximum urinary flow rate (Qmax) significantly improved as early as 1 month postoperatively and remained durable for up to 5 years. Significant median percent improvements in IPSS, QoL, and Qmax at 3 months were 51%, 51%, and 66%, respectively. Patients with obstructive median lobes, large prostates (>80 g), small prostates (<30 g), and urinary retention also experienced significant relief in LUTS, with 83% of urinary retention patients becoming catheter independent at a median of 14 days. Most adverse events were transient and nonserious and occurred in 0% to 76% of patients (median 29%), with de novo erectile dysfunction rates ranging between 0% and 3.1%. Surgical retreatment rate ranged between 4.4% and 7.5% at 5 years postoperatively. Rezum provides durable improvements in symptoms, irrespective of prostate volume and urinary retention status, and has low rates of sexual dysfunction.
Study Design. A retrospective comparative cohort study. Objective. To compare outcomes of elective non-obese anterior cervical discectomy and fusion (ACDF) patients with those that underwent bariatric surgery (BS). Summary of Background Data. Morbid obesity (MO) has been associated with an increased risk of complications following procedures such as elective ACDF. While pre-emptive BS has been considered for those with MO (body mass index [BMI] ≥35 kg/m2), the impact of this intervention on BMI and its resultant correlation with surgical outcomes remains limited. Methods. The PearlDiver 2010-Q1 2020 MSpine database was used to identify patients undergoing elective isolated ACDF. Three sub-cohorts were defined as follows: (1) Non-obese controls without a history of BS, (2) patients with BS procedure within two years with a BMI <35 kg/m2 (BS+MO-), and (3) patients with BS procedure within the two years with a BMI ≥35 kg/m2 (BS+MO+). Univariate and multivariate regression analyses were performed to compare 90-day adverse event rates adjusting for age, sex, Elixhauser Comorbidity Index, and length of stay. Kaplan-Meier analysis was performed to assess five-year cervical reoperation rates. Results. Of 160,166 elective ACDF patients, prior BS was identified for 479. Of these, 136 patients were BS+MO- and 343 were BS+MO+. On multivariate analysis, BS+MO- were not at increased odds of adverse events, but BS+MO+ were at greater odds of 90-day pulmonary embolism (odds ratio 3.28, P=0.043), wound dehiscence (5.02, P<0.001), hematomas (2.52, P=0.042), and overall minor adverse events (1.61, P=0.011) compared with controls. Five-year reoperation rates were not significantly different between the groups. Conclusion. Twenty-eight percent of those with BS before ACDF fell out of the categorization of MO. Among this group, the odds of adverse events were similar to non-obese patients. These findings suggest that the psychological preparation and BS alone are insufficient to reduce the risk of adverse events after ACDF. Weight reduction must be achieved as well, ideally moving patients out of the BMI range for morbid obesity.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
