Background: Despite resuscitative efforts, cardiac arrest (CA) continues to result in high mortality and poor prognosis. However, a gap remains in understanding the comparative outcomes of efforts in emergency departments (ED) over recent years. This study evaluated patients with CA during ED visits, with a particular focus on outcomes of mortality and transition of care. Methods: We conducted a retrospective cohort analysis using the National Emergency Department Sample (NEDS) database. The study population included patients aged 18 years or older who visited the ED between January 2016 and December 2020. Statistical analysis of patients and hospital characteristics included chi-squared tests for independence and multivariable logistic regression models to report the associations of factors with mortality in the ED and disposition from the ED. The primary outcome measured was mortality in the ED, and the secondary outcome included transition of care. Results: A total of 699,822,424 ED visits occurred between 2016 and 2020, with 1,414,060 (0.20%) CAs. The survival rate from CA ranged from 24.6% to 28.1%. In 2020, the rate of ED CA increased to 0.27%, with an inpatient mortality rate of 58.8%. There was no significant difference in mortality between sexes (p = 0.690). There was a trend for higher mortality in the ED among patients who were self-paid. Notably, the odds of transfer from the ED to other hospitals were significantly lower in minority groups. Conclusions: Our results showed significant disparities in ED mortality and patient disposition following cardiac arrest, highlighting the need for equitable healthcare resources and policies.

Introduction: Total Hip Arthroplasty (THA) has revolutionized orthopaedic surgery, with demand expected to double by 2030. This umbrella review assessed the efficacy and patient satisfaction of the direct anterior approach (DAA) versus the posterior approach (PA). Methods: We searched three databases. Quality was assessed using A Measurement Tool to Assess Systematic Reviews 2 (AMSTAR-2), and discrepancies were investigated through matrices (PROSPERO: CRD42023450069). Results: Of 11 SRs/MAs comparing DAA to PA, two were low and nine critically low quality. PA reduced operation duration (OD) in five out of eight direct meta-analyses (DMAs) (mean difference [MD] 13.74 to 18.92). PA showed less blood loss (BL) in one DMA (MD 91.87 [27.99, 155.74]), while DAA showed less BL in another (MD -67.02 [-131.46, -2.58]). DAA decreased length of stay (LOS) in three DMAs (MD -0.31 to -0.56). DAA also showed less pain on post-operative days (POD) 1 and 2 in two DMAs (MD -0.65 [-0.91, -0.38] and MD -0.67 [-1.34, -0.01]). No significant differences were observed at post-operative weeks (POW) 2, POW6, or post-operative months (POM) 12. DAA significantly improved hip function at POW2 in one DMA and POW6 in two DMAs and one network meta-analysis (NMA) (MD 3.7 to 6.80), but no significant differences were found at POM6 or POM12. Discrepancies in OD, BL, and LOS results stemmed from study selection factors including non-randomization, language barriers, approach comparisons, search periods, and inconsistencies in reporting. Conclusion: DAA offers advantages in early pain reduction and functional improvement due to its muscle-sparing technique.

This narrative review aims specifically to explore the relationship between tobacco exposure and systemic sclerosis (SSc), idiopathic inflammatory myositis (IIM), and systemic lupus erythematosus (SLE). Relevant articles were obtained by searching key terms such as “tobacco,” “smoking,” “scleroderma,” “myositis,” “lupus,” and “Sjögren’s” in PubMed and Google Scholar databases. The selected articles ranged from the years 2010 to 2023. Inclusion criteria were based on the relevance and contribution to the field of study. Systemic sclerosis is a complex condition involving multiple immune cell lines that can be influenced by tobacco. However, the existing literature does not provide sufficient evidence to support an increased risk of SSc in smokers or the impact on treatment options. Cigarette smoking does increase the risk of skin ulcerations in SSc patients. In addition, cigarette smoking has been associated with IIM through genetic and molecular mechanisms. Smokers with dermatomyositis or polymyositis are at an elevated risk of atherosclerosis and interstitial lung disease. Similarly, smoking in patients with SLE increases the risk of organ damage, thrombosis, and disease severity compared with non-smokers. Smokers with SLE also have more difficulty in controlling disease flares compared with non-smokers. Tobacco exposure can lead to secondary complications in patients with IIM and SLE, although the course of treatment may not differ significantly. No definitive conclusions can be drawn to the clear relationship between tobacco smoking and Sjögren’s’s syndrome.

Diabetic cardiomyopathy (DCM) is a major complication of type 2 diabetes mellitus (T2DM) that leads to significant morbidity and mortality. The alteration in the signaling mechanism in diabetes leading to cardiomyopathy remains unclear. The purpose of this study is to investigate the role of tauopathy in myocardial dysfunction observed in T2DM. In that regard, diabetic Sprague Dawley rats were treated with intraperitoneal injections of lithium chloride (LiCl), inhibiting tau phosphorylation. Cardiac function was evaluated, and molecular markers of myocardial fibrosis and the TGF-β signaling were analyzed. T2DM rats exhibited a decline in ejection fraction and fractional shortening that revealed cardiac function abnormalities and increased myocardial fibrosis. These changes were associated with tau hyperphosphorylation. Treating diabetic rats with LiCl attenuated cardiac fibrosis and improved myocardial function. Inhibition of GSK-3β leads to the suppression of tau phosphorylation, which is associated with a decrease in TGF-β expression and regulation of the pro-inflammatory markers, suggesting that tau hyperphosphorylation is parallelly associated with fibrosis and inflammation in the diabetic heart. Our findings provide evidence of a possible role of tau hyperphosphorylation in the pathogenesis of DCM through the activation of TGF-β and by inducing inflammation. Targeting the inhibition of tau phosphorylation may offer novel therapeutic approaches to reduce DCM burden in T2DM patients.

Objective: Our study aims to compare the performance of different large language model chatbots on surgical questions of different topics and categories. Materials and Methods: Four different chatbots (ChatGPT 4.0, Medical Chat, Google Bard, and Copilot Ai) were used for our study. 114 multiple-choice surgical questions covering 9 different topics were entered into each chatbot, and their answers were recorded. Results: The performance of ChatGPT was significantly better than Bard ( P < 0.0001) and Medical Chat ( P = 0.0013) but not significantly better than Copilot ( P = 0.9663). We also found a statistically significant difference in ENT ( P = 0.0199) and GI ( P = 0.0124) questions between each chatbot when we assessed their performances per surgical specialty. Finally, the mean scores of Bard, Copilot, Medical Chat, and ChatGPT 4.0 on the diagnosis questions were higher than those in the management questions. The difference was only statistically significant, however, for Bard ( P = 0.0281). Conclusion: Our study offers insight into the performance of different chatbots on surgery-related questions and topics. The strengths and shortcomings of each can provide us with a better understanding of how to use Chatbots in the surgical field, including surgical education.

Disparities in access and outcomes in advanced malignancies encompass, result from, and are interlinked with a host of dimensions, including genetic factors, racial and gender inequities, and socioeconomic status (SES). There are limited data on the existing disparities in patients with peritoneal carcinomatosis (PC) undergoing cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC). Our review aims to discuss these disparities, highlighting the role of race, gender, SES, and distance from healthcare facilities in the utilization of these crucial therapies. Although equal access to treatment for PC remains a hurdle, there are no disparities in the severity and extent of peritoneal cancer, the aggressiveness of cancer, or its response to treatment between White and African American individuals. Males are more likely to undergo CRS and HIPEC for peritoneal metastasis despite a lower prevalence compared to females. Females, however, have increased overall survival and lower 30-day mortality. There is an association between higher SES and private insurance with better access to such therapeutic modalities. Patients with lower SES have an increased number of comorbidities, delays in diagnosis, and significantly lower overall survival. Lower SES patients are at a further disadvantage, as CRS and HIPEC are complex procedures that require specialized expertise and infrastructure, which is typically concentrated in urban areas. These disparities can be addressed by providing equal access, education, and virtual care solutions, which are essential to bridge these gaps and ensure that all patient populations have the opportunity to benefit from advancements in CRS and HIPEC.
