BACKGROUND: Up to 85% of patients with sickle cell disease (SCD) will develop gallstones by their third decade. Cholecystectomy is the most commonly performed procedure in these patients. Cholecystectomy is recommended for patients with SCD with symptomatic cholelithiasis and leads to lower morbidity. No contemporary large studies have evaluated this recommendation or associated clinical outcomes. This study evaluates clinical outcomes after cholecystectomy in patients with SCD and cholelithiasis with specific advanced clinical presentations. STUDY DESIGN: The Nationwide Inpatient Sample was queried for patients with SCD and gallbladder disease between 2006 and 2015. Patients were divided into groups based on their disease presentation, including uncomplicated cholelithiasis, acute and chronic cholecystitis, and gallstone pancreatitis. Clinical outcomes associated with disease presentation were analyzed. Statistical analysis was performed using the Student’s t-test, chi-square test, ANOVA, and logistic regression. RESULTS: There were 6,662 patients with SCD who presented with cholelithiasis. Median age was 20 (interquartile range 16 to 34) years and 54% were female patients. Cholecystectomy was performed in 1,779 patients with SCD with the most common indication being chronic cholecystitis (44%), followed by uncomplicated cholelithiasis (27%), acute cholecystitis (21%), and choledocholithiasis or gallstone pancreatitis (8%). On multivariable regression, advanced clinical presentation was the strongest predictor of perioperative vaso-occlusive crisis, which was the most common complication. Patients undergoing cholecystectomy for uncomplicated cholelithiasis were at lower risk than those with acute cholecystitis (odds ratio [OR] 2.37; 95% CI 1.64 to 3.41), chronic cholecystitis (OR 1.74; 95% CI 1.26 to 2.4), and choledocholithiasis or gallstone pancreatitis (OR 2.24; 95% CI 1.41 to 3.57). CONCLUSIONS: Seventy-three percent of patients with SCD have advanced clinical presentation at the time of their cholecystectomy. After cholecystectomy, perioperative vaso-occlusive events were significantly increased in patients with advanced clinical presentation. These data support screening abdominal ultrasounds and early cholecystectomy for cholelithiasis in patients with SCD.

AbstractBackground and purposeDespite it being an immunotherapy‐responsive neurological syndrome, patients with autoimmune encephalitis (AE) frequently exhibit residual neurobehavioural features. Here, we report criminal behaviours as a serious and novel postencephalitic association.MethodsThis retrospective cohort study included 301 AE patients. Five of who committed crimes underwent direct assessments and records review alongside autoantibody studies.ResultsFive of 301 patients (1.7%) with AE exhibited criminal behaviours, which included viewing child pornography (n = 3), repeated shoplifting, and conspiracy to commit murder. All five were adult males, with LGI1 autoantibodies (n = 3), CASPR2 autoantibodies, or seronegative AE. None had evidence of premorbid antisocial personality traits or psychiatric disorders. Criminal behaviours began a median of 18 months (range = 15 months–12 years) after encephalitis onset. At the time of crimes, two patients were immunotherapy‐naïve, three had been administered late immunotherapies (at 5 weeks–4 months), many neurobehavioural features persisted, and new obsessive behaviours had appeared. However, cognition, seizure, and disability measures had improved, alongside reduced autoantibody levels.ConclusionsCriminal behaviours are a rare, novel, and stigmatizing residual neurobehavioural phenotype in AE, with significant social and legal implications. With caution towards overattribution, we suggest they occur as part of a postencephalitis limbic neurobehavioural syndrome.

For patients with locoregionally confined pancreatic ductal adenocarcinoma (PDAC), margin-negative surgical resection is the only known curative treatment; however, the majority of patients are not operable candidates at initial diagnosis. Among patients with resectable disease who undergo surgery alone, the 5-year survival remains poor. Adjuvant therapies, including systemic therapy or chemoradiation, are utilized as they improve locoregional control and overall survival. There has been increasing interest in the use of neoadjuvant therapy to obtain early control of occult metastatic disease, allow local tumor response to facilitate margin-negative resection, and provide a test of time and biology to assist with the selection of candidates most likely to benefit from radical surgical resection. However, limited guidance exists regarding the relative effectiveness of treatment options. In this systematic review, the American Radium Society multidisciplinary gastrointestinal expert panel convened to develop Appropriate Use Criteria evaluating the evidence regarding neoadjuvant treatment for patients with PDAC, including surgery, systemic therapy, and radiotherapy, in terms of oncologic outcomes and quality of life. The evidence was assessed using the Population, Intervention, Comparator, Outcome, and Study (PICOS) design framework and “Preferred Reporting Items for Systematic Reviews and Meta-analyses” 2020 methodology. Eligible studies included phases 2 to 3 trials, meta-analyses, and retrospective analyses published between January 1, 2012 and December 30, 2022 in the Ovid Medline database. A summary of recommendations based on the available literature is outlined to guide practitioners in the management of patients with PDAC.

Purpose: New 2022 European Society of Cardiology/European Respiratory Society PAH guidelines recommend treatment guided by a multi-parameter risk assessment. 1 Patients with low/intermediate risk without cardiopulmonary comorbidities should start dual PAH combination therapy; those with cardiopulmonary comorbidities should be reassessed early for rapid escalation to dual therapy. Initial triple therapy is recommended for high-risk patients. We examined use of dual and triple PAH therapy in the US (before guideline update). Methods: We used the Pulmonary Hypertension Association Registry (PHAR), a prospective US registry of pulmonary hypertension (PH) patients, enrolled within 6 months of their first outpatient visit at one of 54 participating PH care centers in the US, between Sep 2015-Jun 2022. We included adults (≥18 years at enrollment) with incident PAH (newly diagnosed and treated within 6 months of enrollment) and ≥1 follow-up clinic visit post baseline visit. Chronic thromboembolic PH patients were excluded. Results: We analyzed (descriptive statistics) 794 incident patients (baseline characteristics in Table 1). Treatment patterns at baseline (n=794)/last follow-up visit (n=610) were 289 (36.4%)/102 (16.7%) on monotherapy, 419 (52.8%)/314 (51.5%) on dual combination, 83 (10.5%)/179 (29.3%) on triple combination therapy, respectively. Mean time from enrollment to dual and triple combination therapy was 86.1 (standard deviation [SD]: 209.0) and 346.1 days (SD: 430.8), respectively. Conclusions: Among incident PHAR patients, half received initial dual and 10% triple upfront combination therapy. At last follow-up, most (>80%) patients had escalated to dual/triple combination therapies. Clinical Implications: At PH care centers, most incident PHAR patients are escalated to dual and triple therapy (at last follow-up) per current guidelines. Reference 1. Humbert M, et al.
