  In patients undergoing iliosacral resections, pelvic ring reconstruction can maintain stability of the pelvis and spinal column, which is expected to achieve good functional outcomes. However, no optimal reconstruction method has been established.  https://www.selleckchem.com/products/ginkgolic-acid-s9432.html  We aimed to analyze the outcome of pelvic ring reconstruction using double-barreled free vascularized fibular graft (FVFG) and internal fixation after iliosacral resections in children.
 
  We retrospectively reviewed 16 children with pelvic Ewing sarcoma who underwent pelvic ring reconstruction using double-barreled FVFG after iliosacral resection. The fibular graft was placed between the supraacetabular region distally and the remaining ilium or sacrum proximally. The stability of the remaining pelvis and spinal column was provided by minimal spinal instrumentation.
 
  Eleven Type-I and 5 Type-I+IV resections were performed for 10 boys and 6 girls, who had a mean age of 13.4 years (range, 10 to 18 years). The mean follow-up was 49.8 months (range, 28 to 96 months). At the time of the final follow-up, 14 patients were alive and 2 patients had died of disease. The mean time for bone union was 9 months (range, 6 to 12 months). Graft hypertrophy was evident in all patients at 12 months. The median Musculoskeletal Tumor Society (MSTS) score at the time of the final follow-up was 80% (range, 60% to 96.6%). Seven patients had complications. Three complications required reoperation 1 deep infection, 1 hematoma, and 1 wound dehiscence. Three patients had disease relapse in terms of lung metastases.
 
  This reconstruction method can achieve a high rate of bone union and can provide good functional outcomes following resection of pediatric pelvic Ewing sarcomas with iliosacral involvement. Complications are usually manageable without a need for revision surgical procedures.

  Schizophrenia impairs a patient's self-care abilities, which are crucial after a hip fracture. Studies on the outcomes of patients with schizophrenia after a hip fracture are dated. This study aims to investigate the complication rates, 1-year mortality, and functional outcomes of surgically managed hip fractures in elderly patients with schizophrenia.
 
  This is a retrospective, single-institution cohort study based on a prospectively maintained registry of patients with hip fracture. In this study, 3,056 patients who were ≥60 years of age were treated under a geriatric-orthopaedic hip fracture pathway from January 2014 to December 2018. Baseline demographic characteristics and the Modified Barthel Index (MBI) scores were obtained at admission and at 6 months and 1 year after the fracture. Complications from the fracture and the surgical procedure were recorded during a minimum follow-up period of 2 years. A matching process (based on age, sex, and the MBI at admission) of up to 6 patients without schizophrafter a surgical procedure for hip fracture is similar in both patients with schizophrenia and those without schizophrenia. Patients with schizophrenia and hip fracture who were surgically managed had poorer 1-year functional outcomes compared with patients without schizophrenia matched for age, sex, and MBI at admission. This information will be useful in shared decision-making discussions with patients and families.

  Optimizing beta-lactam antibiotic treatment is a promising method to reduce the length of intensive care unit (ICU) stay and therefore reduce ICU costs. We used data from the EXPAT trial to determine whether beta-lactam antibiotic target attainment is a cost determinant in the ICU.
 
  Patients included in the EXPAT trial were divided into target attainment and target non-attainment based on serum antibiotic levels. All hospital costs were extracted from the hospital administration system and categorized.
 
  In total, 79 patients were included in the analysis. Target attainment showed a trend toward higher total ICU costs (€44,600 vs. €28,200, p=0.103). This trend disappeared when correcting for ICU length of stay (€2,680 vs. €2,700). Renal replacement therapy was the most important cost driver.
 
  Target attainment for beta-lactam antibiotics shows a trend toward higher total costs in ICU patients, which can be attributed to the high costs of a long stay in the ICU and renal replacement therapy.

  Fusion of a joint reportedly increases force in the adjacent joints and leads to progression of arthritis. Whether lumbar spinal fusion increases force in the hip joint and promotes wear of the joint space is unclear. The purpose of this study was to evaluate the rate of joint-space narrowing in the hip following spinal fusion and to examine the effects of the number of levels fused on the joint-narrowing rate.
 
  We retrospectively reviewed data for patients who underwent lumbar spinal fusion from 2011 to 2018 at our institute. Patients with a previous hip surgery, Kellgren-Lawrence grade ≥II hip osteoarthritis, hip dysplasia, and rheumatoid arthritis were excluded. The rate of joint-space narrowing in the hip was measured in 205 eligible patients (410 hips) following spinal fusion, and the effects of sex, age, body mass index, indication for spinal fusion, laterality, sacral fixation, and number of levels fused on the narrowing rate were examined.
 
  The rate of joint-space narrowing for all patients was 0.
