Both cancer patients and the elderly are at high risk of developing flu complications, so influenza vaccination is recommended. We aimed to evaluate potential adverse events (AEs) following influenza vaccination in elderly cancer patients using the self-controlled tree-temporal scan statistic method. From a large linked database of Korea Disease Control and Prevention Agency vaccination data and the National Health Insurance Service claims data, we identified cancer patients aged over 65 who received flu vaccines during the 2016/2017 and 2017/2018 seasons.

Article Synopsis
  • The study investigates the risk factors for carbapenem-resistant Enterobacterales (CRE) bloodstream infections in children with cancer or post-hematopoietic stem cell transplant (HSCT) over a nine-year period in Colombia.
  • Researchers analyzed data to create and validate three prediction models to identify the risk of CRE based on infection types and antibiotic use.
  • Key findings show that infections from Klebsiella spp. and recent carbapenem use significantly increase CRE risk, with a predictive model demonstrating high specificity and effectiveness for identifying patients who may not need CRE-active treatments.

Article Synopsis
  • The study investigates how the immune responses (antibodies and CD4 T cells) to SARS-CoV-2 from natural infection and vaccination change over time, focusing on variants like Mu, Gamma, and Delta.
  • It found that antibody levels decline after 6 months, particularly in mildly infected individuals, while those severely infected maintain higher levels; vaccination boosts antibody production but they also decrease over time.
  • The cross-recognition of variants showed varying effectiveness, and prior exposure to the virus influenced the immune response, suggesting important considerations for future vaccine development against emerging variants.

Does intraoperative fluoroscopy improve acetabular component positioning and limb-length discrepancy during direct anterior total hip arthroplasty? A meta-analysis.

J Orthop Surg Res

August 2023

Department of Orthopedic, Beijing Tsinghua Changgung Hospital, School of Clinical Medicine, Tsinghua University, No.168 Litang Road, Dongxiaokou Town, Changping District, Beijing, 102218, China.

Background: The positioning of implant components for total hip arthroplasty (THA) is essential for joint stability, polyethylene liner wear, and range of motion. One potential benefit of the direct anterior approach (DAA) for THA is the ability to use intraoperative fluoroscopy for acetabular cup positioning and limb-length evaluation. Previous studies comparing intraoperative fluoroscopy with no fluoroscopy during DAA have reported conflicting results.

Background: Non-alcoholic fatty liver disease (NAFLD) is common and is associated with cardiovascular (CV) disease and mortality. The Framingham steatosis index (FSI) was recently proposed as a diagnostic marker of NAFLD and was calculated from age, body mass index, triglyceride, aspartate aminotransferase, alanine aminotransferase, diabetes history, and hypertension status. We aimed to evaluate the predictive ability of FSI for CV risk using a large-scale population dataset from the Korean National Health Insurance Service-National Health Screening Cohort (NHIS-HEALS).
