Objective The aim of this study was to analyze the effects of preoperative echocardiography on patient survival, timing of surgery in length of hospital stay in patients who will undergo hip nailing for an intertrochanteric fracture. Methods The clinical records of the patients who were admitted to a tertiary university hospital with an intertrochanteric femur fracture were retrospectively analyzed. The age, gender, American Society of Anesthesiologists (ASA) score, days to surgery, total hospital stay, cardiac drug prescription/modification, cardiac intervention and presence of an echocardiography assessment including detailed findings were reviewed. Mortality data were accessed from the national civil registration system. Results 181 (110 women and 71 men; mean age 81 (44–98)) cases were studied whom 65 underwent pre-operative echocardiography. Time to surgery and total hospital stay was 2 days longer at transthoracic echocardiography (TTE) group (p < 0.001). At one month control group survival rate was 93.1% on contrary it was 75.4% at TTE group. One-year survival rates were 77.3% and 55.1% respectively. Likewise mean expected survival time was 21.6 ± 1.03 months for control group and 15.12 ± 1.64 months for TTE group (p < 0.001). Only increased left ventricular end diastolic diameter (LVEDD) was showed to be associated with increasing one-year mortality with a hazard ratio of 10.78 (2.572–45.19) at multivariate model. Conclusion Cardiac findings and requisite for preoperative TTE and increased LVEDD is a strong predictor for mortality. TTE significantly lengthens the time to surgery. Also LVEDD measurement can be easily performed in the bedside which we believe would save time and reduce mortality. Level of evidence Level III Diagnostic study.

Purpose Most of the internet users search online on YouTube for their health problems and the treatments. The purpose of this study is to evaluate the quality and the reliability of the videos on YouTube for Carpal tunnel syndrome (CTS). Methods The search was made by typing the keywords “Carpal tunnel syndrome” and/or “CTS” into the YouTube search engine, the first 50 videos on the first three pages of YouTube were evaluated. Of these videos, title, duration, number of views, days since uploaded, view ratio (view per day), number of likes, number of dislikes, video power index (VPI), video source, and video content data were recorded. The Journal of the American Medical Association (JAMA) benchmark criteria were used to evaluate the reliability of videos, where the Global Quality Score (GQS) and Carpal tunnel syndrome-specific score (CTS-SS) were used to evaluate the quality of the videos. Results The mean duration of the videos was 364.12 seconds (min 57, max 1,638) and the total duration of videos was 18,206 seconds. The mean number of views was 140,916.1 (min 10,543, max 1,271,040) and total number of views was 7,045,804. The mean JAMA score was 1.8 (min 1, max 4), the mean GQS was 2.72 (min 1, max 5), and the mean CTS-SS was 4.74 (min 1, max 14). There was no significant effect of video content on VPI, JAMA, GQS, or CTS-SS (p >0.05). The JAMA, GQS, CT-SS scores of the videos from physicians and academic sources were significantly higher compared with other sources (p <0.05). Conclusion YouTube is one of the most frequently used resource for patients to get information about their diagnosis and treatment methods and it consists of videos with low reliability and quality for CTS. We believe that the creation of an internet-based information resource, which the patients can refer to is one of the current social responsibilities of the physicians and the academicians. Level of Evidence This is a Level V study.

Objective: Fear of falling, anxiety, depression, and pain levels are important risk factors for poor functional outcomes that may potentially be modifiable. We aimed to examine prospective associations between those factors following surgery for intertrochanteric hip fracture. Methods: This study is a prospective observational cohort study of patients aged over 65 diagnosed with isolated intertrochanteric hip fracture. Three hundred and seventy patients who underwent intramedullary fixation surgery were screened; 188 cases were included in our final evaluation. Patients with any concomitant fracture, major psychiatric/neurocognitive and neurological disorders and those with any other major disease were excluded from the study. Age, Charlson Comorbidity Index (CCI), Geriatric Depression Scale (GDS), State–Trait Anxiety Inventory (STAI), Falls Efficacy Scale International (FES-I), and Visual Analog Scale (VAS) scores on the day of surgery (baseline) were evaluated as predictors of poor/good outcome at 90 days after surgery, by Harris Hip Score (HHS) with a cut-off score of 70. Results: HHS score was significantly predicted at baseline by the full model [χ2 (7) = 18.18, P = .01]. However, only STAI-state scores were significantly added to the model [Exp (B) 95% CI: .92 (.86-.99)]. Conclusions: In this prospective cohort study, we found that higher levels of anxiety state on the day of surgery predicts a poor outcome at 90 days following surgery. We did not find significant associations between other variables, including age, GDS, STAI-trait, FES-I, VAS, and CCI. This potentially modifiable psychological factor may inform surgeons and could be a potential mediator. Future prospective studies are needed to replicate these findings. Level of evidence: Prognostic level I.
