ABSTRACT Background Geriatric screening and multidisciplinary assessment of older adults in the Emergency Department (ED) decrease hospitalizations and ED revisits. The impact on patient‐reported outcomes of health‐related quality of life (HRQoL) and functional status is not known. Methods A hybrid type II implementation/effectiveness prospective cohort study was conducted in an academic ED. The intervention bundle was geriatric screening for delirium, fall risk, and transition of care needs, and multidisciplinary assessment. All older adults (≥ 65 years) placed in the ED observation unit were eligible. HRQoL and functional status were obtained at the ED visit, 30, and 90 days, and were compared between the pre‐ and post‐intervention implementation cohorts. Secondary outcomes included ED revisits, falls, mortality, and intervention adoption measures. Results From 2019 to 2023, 368 adults participated in the study: Most were community‐dwelling (97%) and had multiple comorbidities. The pre ( n = 138) and post ( n = 230) cohorts did not differ in baseline functional status or HRQoL. The rate of geriatric screening improved from 12.3% in the pre‐implementation cohort to 91.3% in the post‐implementation cohort ( p < 0.01). Multispecialty consultation also increased (68.1%–91.3%, p < 0.01). The proportion who had a post‐ED visit decline in functional status did not differ between cohorts. Physical HRQoL declined similarly in both cohorts (−0.73 vs. −0.33, p = 0.61) at 90 days. Mental HRQoL improved in both cohorts; improvement was greater in the pre‐cohort (2.35 vs. 0.32, p = 0.02). ED revisits and re‐hospitalizations were unchanged (30 days: 23.0% vs. 17.2%, p = 0.18, and 90 days: 37.8% vs. 34.8%, p = 0.57). The intervention decreased falls at 30 and 90 days (30 days: 9.7% vs. 3.2%, p = 0.04; 90 days: 22.1% vs. 7.9%, p < 0.01). Conclusions Geriatric screening in the ED increased identification of geriatric syndromes and multidisciplinary consultation. The intervention was associated with decreased falls but did not affect HRQoL or reduce functional decline post ED visit. Trial Registration clinicaltrials.gov : NCT04068311

Abstract Anterior cruciate ligament reconstruction (ACLR) using bone–patellar tendon–bone autograft remains one of the most common autografts used, and there is significant evidence to support its title as the “gold standard.” There are nuances and technical challenges associated with every step of an ACLR, which always leave room for improvement. The purpose of this Technical Note is to provide reproducible, technical pearls where errors are commonly encountered during ACLR. In this article, we detail 10 technical pearls that surgeons should consider to enhance operative workflow and optimize success during ACLR with a bone–patellar tendon–bone autograft.

Purpose: To assess the prevalence, associated conditions, diagnostic and treatment modalities, and provider education regarding the diagnosis and management of keratoconus (KCN) in sub-Saharan Africa (SSA) based on the currently available body of literature. Methods: Peer-reviewed publications from any year and any language were included. The databases included Cochrane Database of Systematic Reviews, Embase, and Ovid. A separate search of African Journals Online was conducted using the same Medical Subject Heading (MeSH) terms as the database search. Additional publications were identified in the references during full-text extraction. The abstracts of all publications were evaluated by two reviewers. The full text was then examined by one reviewer for inclusion. A data extraction tool was used by a single reviewer to document the findings. Results: Sixty-two publications were included in data extraction. Fourteen countries in SSA were represented. Prevalence was reported in eight SSA countries and ranged from 0% to 2.8%. The highest prevalence of 1.2% was found in a cross-sectional study in Banjul, Gambia. Diagnosis in urban areas is often made using slit lamps, although some sites had access to keratometry and/or topography, whereas rural areas use penlight exams alone. Penetrating keratoplasty was reported as an available treatment in 14 manuscripts, glasses and hard contact lenses in 10, and corneal cross-linking in two. Publications discussing provider education reported a knowledge gap. Conclusions: There is a need for increased data on KCN in SSA to better inform public health policy to improve KCN patients’ access to care and quality of life.

Abstract Objective Autoimmune encephalitis is a cause of brain inflammation characterized by auto‐antibodies, which target cell surface neuronal proteins and lead to neuronal dysfunction. The most common form is associated with auto‐antibodies to leucine‐rich glioma‐inactivated 1 (LGI1) protein, the presentation of which includes frequent focal seizures. The exact cause of these auto‐antibodies remains unknown, but established predispositions include overrepresented human leukocyte antigen ( HLA ) alleles. Yet, these HLA alleles are themselves common in the healthy ancestry‐matched population. One potential etiological hypothesis is that an environmental trigger, such as the gut microbiome, interacts with a genetically predisposed individual. Methods To investigate this, we studied 42 patients with LGI1‐antibody encephalitis (LGI1‐Ab‐E) and 27 familial/environmentally matched controls, and performed metagenomic shotgun sequencing, to describe the compositional and functional differences in the gut microbiome. Results We observed that LGI1‐Ab‐E gut microbiomes exhibited a significant reduction in the ratio of Firmicutes (or Bacillota) and Bacteroidetes phyla, which is associated with the dosage of HLA susceptibility allele count in patients with LGI1‐Ab‐E. Furthermore, we identified differences in functional gene profiles in the gut microbiome that led to a reduction of neuroinflammatory protective short‐chain fatty acids (SCFAs) in LGI1‐Ab‐E patients. Significance Taken together, our results suggest that a compositional shift in the gut microbiome of LGI1‐Ab‐E associates with a neuroinflammatory state, possibly through the reduction of SCFA production. Our study highlights the potential of the gut microbiome to explain some of the complex condition and unravel etiological questions. Validation studies with greater sample sizes are recommended.

Gastrointestinal (GI) defects pose a significant clinical challenge, impacting patient outcomes and healthcare costs. Endoscopic closure techniques have emerged as effective and minimally invasive approaches to manage these defects. This review explores the various endoscopic techniques, including over-the-scope clips (OTSC), endo suturing systems, through-the-scope (TTS) clips, and the X-Tack system. Each technique offers distinct advantages and limitations, making it suitable for specific clinical scenarios. While these devices have demonstrated promising results in clinical practice, further research is needed to optimize their use and address knowledge gaps. Large-scale randomized controlled trials are essential to establish evidence-based guidelines for device selection and procedural techniques. By embracing technological advancements and addressing research limitations, the field of endoscopic closure devices has the potential to revolutionize GI care, leading to improved patient outcomes and expanded therapeutic possibilities.

BACKGROUND Approximately 10% of patients report penicillin allergy. Based on historical guidelines, patients with a penicillin allergy should receive an alternative to cephalexin for prophylaxis in dermatologic surgery. OBJECTIVE To determine, based on evidence, if cephalexin should be used as a first-line prophylactic antibiotic in dermatologic surgery for patients with penicillin allergy. METHODS Systematic review of the literature was performed with defined search terms. RESULTS Less than 5% of those with penicillin allergy labels have a true penicillin allergy. For patients with true, persistent penicillin allergy, there is an overall low cross-reactivity with cephalosporins, especially with cephalosporins that do not share identical R1 side chain. The first-generation cephalosporins, including cephalexin, have a slightly higher risk of cross-reactivity in patients with reported allergy to amino-penicillins (amoxicillin, ampicillin) but not other penicillins. The risk of severe cross-reactivity of cephalosporins in patients with low-risk penicillin allergies is extremely low. Cephalexin has a superior side effect profile and efficacy compared to alternatives. CONCLUSION Cephalexin should be used as the first-line prophylactic antibiotic in dermatologic surgery for patients with documented penicillin allergy, including anaphylaxis. There may be a higher risk of cross-reactivity with cephalexin in patients with a confirmed amino-penicillin allergy.

Abstract Background: With over 1 billion individuals affected globally, obesity and obesity related diseases is now a leading cause of death. Metabolic and bariatric surgery (MBS) has emerged as a cornerstone intervention for severe obesity and its associated comorbidities. Despite its efficacy, postoperative care and follow-up after MBS remains highly variable worldwide. Objective: The PARTNER study aimed to evaluate global clinical practices in the postoperative management following MBS by surveying multidisciplinary healthcare professionals . Methods: This study was an international online survey conducted between October 2024 and January 2025. A multidisciplinary team developed the questionnaire based on existing literature and international guidelines. The survey assessed five domains: follow-up care, postoperative treatment, dietary management, patient support, and measurement of surgical outcomes. Responses were analysed descriptively. Results: A total of 262 responses were received from 62 countries. Most respondents were bariatric surgeons (72.1%) working in public healthcare systems (73.3%). While 78.7% reported conducting three-month postoperative reviews, only 23.7% offered indefinite follow-up. Hybrid models of care (virtual and in-person) were common (56.9%). VTE prophylaxis and postoperative PPI use were recommended by 64.1% and 84.3% respectively. Nearly all respondents (98.1%) provided dietary advice, with protein and micronutrient supplementation widely endorsed. Only 56.1% routinely referred patients for psychological follow-up. Definitions of surgical success and failure varied widely, with inconsistent objective outcome measures. Conclusion: The PARTNER study reveals significant international variation in postoperative management practices following MBS. These findings underscore the need for more standardized, evidence-based guidelines to improve long-term outcomes and equity of care worldwide.

OBJECTIVES: To investigate whether severe hyperoxia predisposes to end-organ complications and whether these complications contribute to in-hospital mortality among cardiogenic shock (CS) patients supported in venoarterial extracorporeal membrane oxygenation (VA-ECMO). DESIGN: Adult patients with CS from the Extracorporeal Life Support Organization Registry between 2010 and 2023 were categorized into normoxia (Pao 2 60–150 mm Hg), mild hyperoxia (Pao 2 151–300 mm Hg), and severe hyperoxia (Pao 2 > 300 mm Hg) based on their Pao 2 at 24 hours. The primary outcome was in-hospital mortality. End-organ complications were analyzed using multivariate logistic regression models, and causal mediation analysis was performed to estimate the direct and indirect effects of hyperoxia on mortality. SETTING: Multicenter, multinational prospective cohort study. PATIENTS: Adults with CS supported on VA-ECMO. INTERVENTIONS: Partial pressure of oxygen at 24 hours after VA-ECMO cannulation. MEASUREMENTS/MAIN RESULTS: A total of 10,541 patients were included (normoxia: 48.4%, mild hyperoxia: 30.0%, severe hyperoxia: 21.5%). There was higher in-hospital mortality in patients with severe hyperoxia (71.7%, adjusted OR [aOR]: 2.17; 95% CI, 1.19–2.50) and mild hyperoxia (63.8%, aOR: 1.34; 95% CI, 1.19–1.50) compared normoxia (52.7%; referent group). Severe hyperoxia was associated with more end-organ complications, which incrementally predicted higher mortality (aOR: 1.42; 95% CI, 1.25–1.61). Mediation analysis demonstrated that hyperoxia primary exerted a direct effect on mortality (86%), with contributions from neurologic (3.1%), hepatic (3.9%), renal (3.5%), and bleeding (2.3%) complications. CONCLUSIONS: Severe hyperoxia in patients with CS receiving VA-ECMO is associated with increased mortality and more end-organ complications. However, most of the effect of severe hyperoxia on mortality occurs via direct effects, independent of end-organ complications. These findings highlight the potential direct toxicity of hyperoxia and underscore the need for strategies to optimize oxygen delivery in this critically ill population.
