To explore how the thickness of the femoral lateral wall influences the effectiveness of internal fixation systems used to treat intertrochanteric fractures. CT images of the pelvis and femur of a male adult were used to construct an intertrochanteric fracture model (AO/OTA 31-A2) with various thicknesses of the femoral lateral wall (FLW). Four finite element (FE) models were created with the lateral femoral walls being 10 mm, 20 mm, 30 mm, and 40 mm thick.

Background: Carbapenem-resistant (CRKP) infection has proven to be difficult to control and typically presents with devastating effects.

Methods: This retrospective study was conducted on the renal recipients at our institution between January 2021 to January 2022. Clinical data was collected to identify factors associated with CRKP infection and clinical outcomes.

Article Synopsis
  • Ferroptosis-related genes (FRGs) are crucial for understanding the survival and prognosis of prostate cancer patients, leading to the development of a predictive model to assess overall and disease-free survival based on immune cell infiltration characteristics.
  • A comprehensive analysis involving 268 FRGs revealed differentially expressed genes using the TCGA database, employing various bioinformatics methods including Cox regression to create prognostic models linked to clinicopathological features.
  • The established models indicated that advanced cancer stages (T3-4) and N0 stages showed better predicted survival rates; additionally, distinct patterns of immune cell infiltration associated with ferroptosis were identified, highlighting the role of specific immune cells in high- and low-risk groups.

Background: Potent immune-suppressive therapy has been demonstrated to increase the risk of infective endocarditis (IE) in renal recipients. Reports of () endocarditis in renal recipients are scarce, thus limiting understanding of the disease.

Case Presentation: We describe a case of native valve endocarditis caused by in a 35-year-old male patient.

Background: Our objective is to build a model based on Prostate Imaging Reporting and Data System version 2 (PI-RADs v2) and assess its accuracy by internal validation.

Methods: Patients who took prostate biopsy from 2014 to 2015 were retrospectively collected to compose training cohort according to the inclusion criteria and patients in 2016 composing validation cohort. Diagnostic performance was evaluated by analyzing the area under the curve (AUC), calibration curves, and decision curves.

Background: We aimed to confirm the advantages of a modified hand-assisted retroperitoneoscopic living donor nephrectomy (HARPLDN) compared to the performance of standard retroperitoneoscopic living donor nephrectomy (RPLDN).

Methods: One hundred twenty-eight consecutive surgical cases were categorized into 2 groups, one receiving standard RPLDN (group 1) and one receiving modified HARPLDN (group 2). Perioperative factors of both groups were evaluated retrospectively, including donors' demographics, overall operating time, warm ischemia time (WIT), graft vessel length, blood loss, complications, pain visual analogue scale (VAS) scores, hospital stay, and matched recipients' perioperative outcomes.

Photodegradation of pollutions by TiO2 under irradiation of weak UV and visible lights was one of the key points to expand the application of heterogeneous photocatalysis. Based on the adsorption phase synthesis, N doping and co-doping with N and Fe2O3 were employed to prepare TiO2 multi composite photocatalysts. The activity of these photocatalyts was evaluated by photodegradation of methyl-orange illuminated under weak UV and visible lights.

Premature ejaculation (PE) is a common sexual disorder in men that is mediated by disturbances in the peripheral and central nervous systems. Although all pharmaceutical treatments for PE are currently used 'off-label', some novel oral agents and some newer methods of drug administration now provide important relief to PE patients. However, the aetiology of this condition has still not been unified, primarily because of the lack of a standard animal model for basic research and the absence of a widely accepted definition and assessment tool for evidence-based clinical studies in patients with PE.
