Background: Assessment of uterine abnormalities is a core part in infertility evaluation.
Objective: The aim of this study was to evaluate the sensitivity and specificity of three-dimensional hysterosonography (3-DHS) in the diagnosis of uterine abnormalities in infertile women.
Materials And Methods: The infertile women who visited Royan Institute and referred to 3-DHS consecutively, prior to in vitro fertilization, from 2010-2011 included in this cross-sectional study. For patients who underwent hysteroscopy in addition to 3-DHS (214/977), the verification bias adjusted sensitivity and specificity of 3-DHS which were calculated by global sensitivity analysis method. Hysteroscopy was used as the gold standard for diagnosis of uterine abnormalities. Histological diagnosis of resected endometrial tissues by hysteroscopy was assessed and the adjusted sensitivity and specificity of 3-DHS and hysteroscopy in detection of polyp or hyperplasia were determined. Histopathologic results were considered as the gold standard for diagnosis of polyp or hyperplasia.
Results: The overall sensitivity and specificity for 3-DHS in diagnosis of uterine anomalies considering hysteroscopy as the gold standard were 68.4% and 96.3% respectively. Sensitivity and specificity of hysteroscopy in diagnose of polyp or hyperplasia was calculated at 91.3% and 81.4% respectively. Sensitivity and specificity of 3-DHS in diagnosis polyps or hyperplasia was calculated at 91.4% and 80.2 % respectively.
Conclusion: The results of present study proved that, compared to hysteroscopy; 3-DHS has a reliable specificity for diagnosis of uterine abnormalities. Sensitivity and specificity of 3-DHS and hysteroscopy in detecting polyp or hyperplasia regarding histopathology as the gold standard was the same.

Background: Recent research has revealed the potential value of machine learning (ML) models in improving prognostic prediction for patients with trauma. ML can enhance predictions and identify which factors contribute the most to posttraumatic mortality. However, no studies have explored the risk factors, complications, and risk prediction of preoperative and postoperative traumatic coagulopathy (PPTIC) in patients with trauma.

Importance: The Walter Index is a widely used prognostic tool for assessing 12-month mortality risk among hospitalized older adults. Developed in the US in 2001, its accuracy in contemporary non-US contexts is unclear.
Objective: To evaluate the external validity of the Walter Index in predicting posthospitalization mortality risk in Brazilian older adult inpatients.
Introduction: Varicella-Zoster virus (VZV) is a highly contagious alpha-herpes virus. The diagnosis of chickenpox remains a difficult task especially in cases of breakthrough chickenpox, so the development of reliable laboratory tests is necessary. The simplest and most sensitive serological test for detecting antibodies in human and animal sera is the passive hemagglutination reaction (PHAR).

Non-alcoholic fatty liver disease (NAFLD) is a highly prevalent chronic liver condition characterized by excessive hepatic fat accumulation. Early diagnosis is crucial as NAFLD can progress to more severe conditions like steatohepatitis, fibrosis, cirrhosis, and hepatocellular carcinoma without timely intervention. While liver biopsy remains the gold standard for NAFLD assessment, abdominal ultrasound (US) imaging has emerged as a widely adopted non-invasive modality due to convenience and low cost.
