Abstract Background and study aims Endoscopic sleeve gastroplasty (ESG) is performed in clinical practice by gastroenterologists and bariatric surgeons. Given the increasing regulatory approval and global adoption, we aimed to evaluate real-world outcomes in multidisciplinary practices involving bariatric surgeons and gastroenterologists across the United States. Patients and methods We included adult patients with obesity who underwent ESG from January 2013 to August 2022 in seven academic and private centers in the United States. Patient and procedure characteristics, serious adverse events (SAEs), and weight loss outcomes up to 24 months were analyzed. SPSS (version 29.0) was used for all statistical analyses. Results A total of 1506 patients from seven sites included 235 (15.6%) treated by surgeons and 1271 (84.4%) treated by gastroenterologists. There were no baseline differences between groups. Gastroenterologists used argon plasma coagulation for marking significantly more often than surgeons (P<0.001). Surgeons placed sutures in the fundus in all instances whereas gastroenterologist placed them in the fundus in less than 1% of the cases (P<0.001>). Procedure times were significantly different between groups, with surgeons requiring approximately 20 minutes more during the procedure than gastroenterologists (P<0.001). Percent total body weight loss (%TBWL) and percent responders achieving >10 and >15% TBWL were similar between the two groups at 12, 18, and 24 months. Rates of SAEs were low and similar at 1.7% for surgeons and 2.7% for gastroenterologists (P>0.05). Conclusions Data from a large US cohort show significant and sustained weight loss with ESG and an excellent safety profile in both bariatric surgery and gastroenterology practices, supporting the scalability of the procedure across practices in a multidisciplinary setting.

AbstractHemifacial spasm is a neuromuscular disorder caused by compression of the facial nerve at the nerve root entry zone, often due to ectatic or aberrant vasculature. Pathologic compression of the nerve–brainstem interface results in involuntary, paroxysmal contractions of ipsilateral facial muscles that may cause considerable impairments in quality of life. For those with severe symptoms, have positive imaging demonstrating vascular compression, or who fail other management modalities,1 2 3 4 microvascular decompression offers potential definitive treatment.5 6 Traditionally, nonabsorbable packing agent is used to pack between the nerve and offending vascular structure. However, for large and more complex arterial structures, simple nonabsorbable padding is often not sufficient.In this operative video, we demonstrate microvascular decompression for intractable hemifacial spasm in a 52-year-old female using a specialized sling tacked to the petrous dura for management of a large, ectatic vertebral artery. Following a standard left retrosigmoid craniotomy, an atheromatous ectatic vertebral artery was identified. We fashioned a bovine pericardium sling around the vessel and used a permanent aneurysm clip to secure it to an incision portion of petrous dura. We subsequently identified potential additional facial nerve root compression by anterior inferior cerebellar artery (AICA) and posterior inferior cerebellar artery (PICA) branches, which were elevated and secured using Teflon felt packing. Following elevation of all three vessels, the lateral spread response resolved. At 2 weeks postoperatively, the patient reported substantial relief in her hemifacial spasms and endorsed highly improved quality of life.

Liver transplantation (LT) is a highly effective treatment for carefully selected patients with hepatocellular carcinoma (HCC). In this review, we explored the development of LT selection criteria and organ allocation policies, comparing original data to underscore their historical progression into the intricate task of quantitatively estimating pre- and post-LT survivals. We emphasized the role of biomarkers such as serum alpha-fetoprotein, Des-gamma-carboxy-prothrombin, circulating tumor cells, and circulating tumor DNA in predicting patient outcomes. Additionally, we examined the transplant-associated survival benefits and the difficulties in accurately calculating these benefits. We also reviewed recent advancements in targeted therapy and checkpoint inhibitors for advanced, inoperable HCC and projected their integration into LT for HCC. We further discussed the growing use of living donor liver transplants in the United States and compared its outcomes with those of deceased donor liver transplants. Furthermore, we examined the progress in machine perfusion techniques, which have shown potential in improving patient outcomes and enlarging the donor pool. These advancements present opportunities to enhance LT patient survivals, refine selection criteria, establish new priority metrics, develop innovative bridging and downstaging strategies, and formulate redesigned LT strategies for HCC treatments.

Objective This study aimed to characterize implicit bias (IB) and health disparities (HD) education in neonatal–perinatal medicine (NPM), including current educational opportunities, resources, and barriers. Study Design A national web-based survey was sent to NPM fellows, neonatologists, and frontline providers after iterative review by education experts from the National Neonatology Curriculum Committee. Quantitative data were analyzed with chi-square and Fisher's exact tests. Qualitative data were evaluated using thematic analysis. Results Of the 452 NPM survey respondents, most desired additional IB (76%) and HD (83%) education. A greater proportion of neonatologists than fellows received IB (83 vs. 57%) and HD (87 vs. 74%) education. Only 41% of neonatologists reported that their institution requires IB training. A greater proportion of fellows than neonatologists expressed dissatisfaction with the current approaches for IB (51 vs. 25%, p < 0.001) and HD (43 vs. 25%, p = 0.015) education. The leading drivers of dissatisfaction included insufficient time spent on the topics, lack of specificity to NPM, inadequate curricular scope or depth, and lack of local educator expertise. A minority of faculty who were tasked to educate others have received specific educator training on IB (21%) and HD (16%). Thematic analysis of survey free-text responses identified three main themes on the facilitators and barriers to successful IB and HD education: individual, environmental, and curricular design variables. Conclusion NPM trainees and neonatologists desire tailored, active, and expert-guided IB and HD education. Identified barriers are important to address in developing an effective IB/HD curriculum for the NPM community. Key Points

Abstract Background: Clinical, molecular, and genetic epidemiology studies displayed remarkable differences between ever- and never-smoking lung cancer. Methods: We conducted a stratified multi-population (European, East Asian, and African descent) association study on 44,823 ever-smokers and 20,074 never-smokers to identify novel variants that were missed in the non-stratified analysis. Functional analysis including expression quantitative trait loci (eQTL) colocalization and DNA damage assays, and annotation studies were conducted to evaluate the functional roles of the variants. We further evaluated the impact of smoking quantity on lung cancer risk for the variants associated with ever-smoking lung cancer. Results: Five novel independent loci, GABRA4, intergenic region 12q24.33, LRRC4C, LINC01088, and LCNL1 were identified with the association at two or three populations (P &lt; 5 × 10−8). Further functional analysis provided multiple lines of evidence suggesting the variants affect lung cancer risk through excessive DNA damage (GABRA4) or cis-regulation of gene expression (LCNL1). The risk of variants from 12 independent regions, including the well-known CHRNA5, associated with ever-smoking lung cancer was evaluated for never-smokers, light-smokers (packyear ≤ 20), and moderate-to-heavy-smokers (packyear &gt; 20). Different risk patterns were observed for the variants among the different groups by smoking behavior. Conclusions: We identified novel variants associated with lung cancer in only ever- or never-smoking groups that were missed by prior main-effect association studies. Impact: Our study highlights the genetic heterogeneity between ever- and never-smoking lung cancer and provides etiologic insights into the complicated genetic architecture of this deadly cancer.

Objective: To identify links between Participatory Health Informatics (PHI) and the One Digital Health framework (ODH) and to show how PHI could be used as a catalyst or contributor to ODH. Methods: We have analyzed the addressed topics within the ODH framework in previous IMIA Yearbook contributions from our working group during the last 10 years. We have matched main themes with the ODH's framework three perspectives (individual health and wellbeing, population and society, and ecosystem). Results: PHI catalysts ODH individual health and wellbeing perspective by providing a more comprehensive view on human health, attitudes, and relations between human health and animal health. Integration of specific behavior change techniques or gamification strategies in digital solutions are effective to change behaviors which address the P5 paradigm. PHI supports the population and society perspective through the engagement of the various stakeholders in healthcare. At the same time, PHI might increase a risk for health inequities due to technologies inaccessible to all equally and challenges associated with this. PHI is a catalyst for the ecosystem perspective by contributing data into the digital health data ecosystem allowing for analysis of interrelations between the various data which in turn might provide links among all components of the healthcare ecosystem. Conclusion: Our results suggest that PHI can and will involve topics relating to ODH. As the ODH concept crystalizes and becomes increasingly influential, its themes will permeate and become embedded in PHI even more. We look forward to these developments and co-evolution of the two frameworks.

AbstractExtended oral antibiotic prophylaxis (EOAP) has been suggested to reduce rates of periprosthetic joint infection (PJI) postoperatively after total joint arthroplasty (TJA). The purpose of this multicenter study is to define how many TJA patients are considered high risk for developing PJI based on published EOAP criteria and determine whether this status is associated with socioeconomic or demographic factors. All primary and aseptic revision TJAs performed in 2019 at three academic medical centers were reviewed. High-risk status was defined based on prior published EOAP criteria. Area deprivation index (ADI) was calculated as a measure of socioeconomic status. Data were reported as means with standard deviation. Both overall and institutional differences were compared. Of the 2,511 patients (2,042 primary and 469 revision) in this cohort, 73.3% met criteria for high risk (primary: 72.9% [1,490] and revision: 74.6% [350]). Patient's race or age did not have a significant impact on risk designation; however, a larger proportion of high-risk patients were women (p = 0.002) and had higher Elixhauser scores (p < 0.001). The mean ADI for high-risk patients was higher (more disadvantaged) than for standard-risk patients (64.0 [20.8] vs. 59.4 [59.4]) (p < 0.001). Over 72% of primary and revision TJA patients at three medical centers met published criteria for EOAP. These patients were more often women, had more comorbidities, and lived in more disadvantaged areas. Our findings suggest that most patients qualify for EOAP, which may call for more stringent criteria on who would benefit extended antibiotic prophylaxis.
