Background: A vast amount of literature is available on the burden of acute ischemic stroke (AIS). Yet, most information on AIS burden does not stratify by stroke severity, and the inclusion of mild strokes (National Institute of Health Stroke Scale < 5) might obscure the true impact of moderate-to-severe AIS. Therefore, it is important to understand the literature as it pertains to the epidemiological, clinical, humanistic, and economic burden of moderate-to-severe AIS from a global perspective. Methods: A systematic literature review (SLR) was conducted, including articles published between January 2015 and June 2023. The clinical burden search focused on patients with moderate or severe AIS. Due to the paucity of evidence, the humanistic and economic burdens were evaluated based on overall AIS studies. Abstract and full-text screening were conducted by 2 reviewers, with data extraction completed by 1 reviewer. In all, 136 studies were included in the SLR. Results: AIS caused a substantial burden for patients and the healthcare system. The clinical burden of AIS (specifically severe AIS) resulted in high mortality and worse functional outcomes across multiple demographics (female sex, older age, and patients with comorbidities). The economic burden of overall AIS was substantial, with inpatient costs as the primary driver (a mean or median stay of 7 days). The highest inpatient costs were reported in South Korea ($45,180) and the United States ($38,470). Conclusions: The review highlighted the huge burden of moderate-to-severe AIS, with patients experiencing worse outcomes with increased stroke severity. Further focus is needed on outcomes relating to moderate-to-severe AIS to fully understand the burden of stroke in this patient population.

Background: The cumulative effect of repetitive subconcussive head impacts on neurocognitive function during youth contact sports remains largely unknown. There is a paucity of literature evaluating cumulative helmet forces over a season and their correlation with preseason and postseason cognitive performance tasks such as the King-Devick test (KDT). Hypothesis: Higher helmet forces recorded throughout a 10-week, 10-game youth football season would correlate with slower performance on postseason KDT. Study Design: Prospective cohort study. Level of Evidence: Level 3. Methods: A cohort of 58 youth football players (ages 9-13 years) underwent pre- and postseason KDT. Players wore SpeedFlex helmets (Riddell) fitted with InSite Impact Response System helmet accelerometers (Riddell) which recorded impacts of ≥15 g . Head impacts were tallied over a season and assigned a score of 1, 2, or 3 based on magnitude of g forces. Suspected concussions were correlated with KDT times and recorded instances of head impact. Pre- and postseason KDT scores were compared. Results: During the season, 2013 head impacts were recorded. Median (range) total cumulative force score was 24 (5-476); 6 players sustained head impacts concerning for concussion, and 4 were clinically diagnosed with concussions. Overall, postseason KDT times improved compared with preseason, with a median (range) change of −4.8 seconds (−7.6, −1.1). Analysis showed no correlation between changes in KDT time and total cumulative force score over the season. Conclusion: KDT times in youth football players did not change significantly based on head impact exposure over a single youth football season; most players’ KDT times improved from preseason to postseason. Clinical Relevance: Although our study did not show significant cognitive impact as measured by KDT over a single youth football season, the long-term effects of concussion on the immature brain and how it can impact cognitive development remains largely unknown and should be an area of ongoing study.

Background To provide recommendations on risk mitigation, diagnosis and treatment of infectious complications associated with the practice of regional anesthesia, acute and chronic pain management. Methods Following board approval, in 2020 the American Society of Regional Anesthesia and Pain Medicine (ASRA Pain Medicine) commissioned evidence-based guidelines for best practices for infection control. More than 80 research questions were developed and literature searches undertaken by assigned working groups comprising four to five members. Modified US Preventive Services Task Force criteria were used to determine levels of evidence and certainty. Using a modified Delphi method, >50% agreement was needed to accept a recommendation for author review, and >75% agreement for a recommendation to be accepted. The ASRA Pain Medicine Board of Directors reviewed and approved the final guidelines. Results After documenting the incidence and infectious complications associated with regional anesthesia and interventional pain procedures including implanted devices, we made recommendations regarding the role of the anesthesiologist and pain physician in infection control, preoperative patient risk factors and management, sterile technique, equipment use and maintenance, healthcare setting (office, hospital, operating room), surgical technique, postoperative risk reduction, and infection symptoms, diagnosis, and treatment. Consensus recommendations were based on risks associated with different settings and procedures, and keeping in mind each patient’s unique characteristics. Conclusions The recommendations are intended to be multidisciplinary guidelines for clinical care and clinical decision-making in the regional anesthesia and chronic interventional pain practice. The issues addressed are constantly evolving, therefore, consistent updating will be required.

AbstractCholecystectomy is the standard treatment for acute cholecystitis, but it may not be suitable for all patients. For those who cannot undergo surgery, a percutaneous cholecystostomy tube (PCT) and ERCP-guided transpapillary gallbladder drainage are viable options. We aimed to perform a nationwide study to assess 30-day readmission rates, adverse events (AEs), and mortality rates in these two cohorts.We conducted a nationwide cohort study using data from the Nationwide Readmissions Database (NRD) from 2016 to 2019. We identified patients with acute cholecystitis during the index admission who underwent either PCT or ERCP-guided gallbladder drainage. Propensity score matching along with multivariable regression was used to compare cohorts.During the study period, 3,592 patients (average age 63.0 years) underwent endoscopic drainage, whereas 80,372 patients (average 70.8 years) underwent Interventional Radiology drainage. Utilizing multivariate Cox regression analysis, compared with ERCP, PCT had a higher risk for 30-day readmission (adjusted hazard ratio [aHR] 1.47; 95% confidence interval [CI] 1.27 to 1.71; P < 0.001). The PCT group had a significantly higher rate of readmission for acute cholecystitis compared with the ERCP group (2.72% vs 0.86%; P < 0.005). Cox proportional hazard ratio showed a 3.41-fold increased risk (95% CI 1.99 to 5.84) for readmission in the PCT group. ERCP was consistently associated with lower rates of post-procedural AEs compared with PCT including acute hypoxemic respiratory failure (P < 0.001), acute renal failure (P < 0.001), shock (P < 0.001), and need for blood transfusions (P < 0.001).Our nationwide analysis revealed that ERCP-guided gallbladder drainage should be the preferred approach for managing acute cholecystitis when unfit for surgery.

Abstract Opioid use disorder (OUD) affects over 40 million people worldwide, creating significant social and economic burdens. Medication for opioid use disorder (MOUD) is often considered the primary treatment approach for OUD. MOUD, including methadone, buprenorphine, and naltrexone, is effective for some, but its benefits may be limited by poor adherence to treatment recommendations. Immunopharmacotherapy offers an innovative approach by using vaccines to generate antibodies that neutralize opioids, blocking them from crossing the blood-brain barrier and reducing their psychoactive effects. To date, only 3 clinical trials for opioid vaccines have been published. While these studies demonstrated the potential of opioid vaccines for relapse prevention, there is currently no standardized protocol for evaluating their effectiveness. We have reviewed recent preclinical studies that demonstrated the efficacy of vaccines targeting opioids, including heroin, morphine, oxycodone, hydrocodone, and fentanyl. These studies showed that vaccines against opioids reduced drug reinforcement, decreased opioid-induced antinociception, and increased survival rates against lethal opioid doses. These studies also demonstrated the importance of vaccine formulation and the use of adjuvants in enhancing antibody production and specificity. Finally, we highlighted the strengths and concerns associated with the opioid vaccine treatment, including ethical considerations.
