We aimed to analyze the prognostic power of CT-based radiomics models using data 14,339 COVID-19 patients.
Breast cancer (BC) is one of the most burdensome cancers worldwide. Despite advancements in diagnostic and treatment modalities, developing countries are still dealing with increasing burdens existing disparities. This study provides estimates BC burden associated risk factors Iran at national subnational levels over 30 years (1990-2019).Data on for were retrieved from Global Burden Disease (GBD) 1990 to 2019. GBD estimation methods applied explore incidence, prevalence, deaths,...
Aim: This study aimed to evaluate the association of FC with gastrointestinal involvement in SSc, focusing on factors such as small intestine wall thickness, esophageal dilation, and skin involvement. Background: Fecal calprotectin (FC) has emerged a promising biomarker for intestinal inflammation, its role systemic sclerosis (SSc) remains under investigation. Gastrointestinal SSc is common can significantly impact quality life, making it crucial identify reliable biomarkers early detection....
Abstract Purpose To derive and validate an effective radiomics-based model for differentiation of COVID-19 pneumonia from other lung diseases using a very large cohort patients. Methods We collected 19 private 5 public datasets, accumulating to 26,307 individual patient images (15,148 COVID-19; 9,657 with e.g. non-COVID-19 pneumonia, cancer, pulmonary embolism; 1502 normal cases). Images were automatically segmented validated deep learning (DL) the results carefully reviewed. first cropped...
Abstract To derive and validate an effective machine learning radiomics‐based model to differentiate COVID‐19 pneumonia from other lung diseases using a large multi‐centric dataset. In this retrospective study, we collected 19 private five public datasets of chest CT images, accumulating 26 307 images (15 148 COVID‐19; 9657 including non‐COVID‐19 pneumonia, cancer, pulmonary embolism; 1502 normal cases). We tested 96 learning‐based models by cross‐combining four feature selectors (FSs) eight...
Abstract Background Notwithstanding the encouraging results of previous studies reporting on efficiency deep learning (DL) in COVID‐19 prognostication, clinical adoption developed methodology still needs to be improved. To overcome this limitation, we set out predict prognosis a large multi‐institutional cohort patients with using DL‐based model. Purpose This study aimed evaluate performance privacy‐preserving federated (DPFL) predicting outcomes chest CT images. Methods After applying...
According to the significance of extraintestinal symptoms in inflammatory bowel disease (IBD) patients and their connection with obesity, we aimed investigate prevalence fatty liver IBD Sayyad Shirazi Hospital Gorgan, Iran, relation anthropometric indicators body image these patients.
Systemic sclerosis (SSc) is a rare autoimmune disorder characterized by vascular and fibrosing involvement of the skin internal organs. In this study, we determined prevalence characteristics radiological hands feet involvements in Iranian SSc patients to identify associations between clinical features radiologic findings.43 (41 women 2 men), with median age 44.8 years (ranges 26-70 years) mean disease duration 11.8 2-28 were studied cross-sectional study.42 had changes both their feet. Only...
One of the most important complications in inflammatory Bowel Disease (IBD) are musculoskeletal manifestations that reported more than 50% patients.In this study, we aimed to evaluate and radiologic our IBD cross-sectional study on 96 mild-to-moderate patients (76 UC, 18 CD 2 undifferentiated IBD) with mean (SD) age 39.28 (11.42) years, 44 (45.8%) were males 52 (54.2%) females. Patients examined by an expert rheumatologist their symptoms assessed. The system was evaluated Modified Schober...
An updated exploration of the burden thyroid cancer across a country is always required for making correct decisions. The objective this study to present and attributed high Body Mass Index (BMI) in Iran at national sub-national levels from 1990 2019. data was obtained GBD 2019 estimates. To explain pattern changes incidence 2019, decomposition analysis conducted. Besides, attribution BMI DALYs deaths were obtained. age-standardized rate 1.57 (95% UI: 1.33-1.86) increased 131% (53-191) until...
Measurement of colonic transit time (CTT) different colon segments can help to find the subtype constipation and appropriate treatment. This study aimed estimate segmental total CTT in patients with refractory chronic who attended gastrointestinal clinics. A cross-sectional was done according ROME IV criteria normal colonoscopy. Patients underlying diseases, including diabetes, hypoparathyroidism, hypothyroidism, anemia, past intestinal surgery, metabolic disorders, recent medication use...
Background: Assessing the measurable chest computed tomography (CT) scan cardiac parameters can help us evaluate cardiovascular involvement and risk stratification in patients with coronavirus disease 2019 (COVID-19). Objectives: This study investigated CT indices their association predicting outcomes COVID-19. Patients Methods: confirmed COVID-19 were included from March up to June 2020 underwent scans on admission. The following analyzed: extent pattern of lung involvement, cardiothoracic...

Retained products of conception (RPOC) occur when fragments the placenta or decidual tissue remain in uterus, often leading to postpartum hemorrhage. Early and accurate diagnosis, aided by ultrasonography, is essential for appropriate management prevention complications. We report a case 22-year-old woman admitted our tertiary medical department with irregular vaginal bleeding abdominal pain. She had no significant past history. Abdominal ultrasonography revealed normal-sized uterus...
Abstract Objective In this large multi-institutional study, we aimed to analyze the prognostic power of computed tomography (CT)-based radiomics models in COVID-19 patients. Methods CT images 14,339 patients with overall survival outcome were collected from 19 medical centers. Whole lung segmentations performed automatically using a previously validated deep learning-based model, and regions interest further evaluated modified by human observer. All resampled an isotropic voxel size,...
Introduction: Heterotopic pregnancy is defined as the simultaneous presence of intrauterine and ectopic pregnancies, manifesting with abdominal pain vaginal bleeding. Previous tubal surgeries pelvic inflammatory diseases increase risk this anomaly. In case report, heterotopic after in vitro fertilization (IVF) a 32-year-old female was reported. Case Presentation: A referred to our medical center, presenting She had IVF seven weeks ago without history any other illness or consuming specific...
We encountered the novel coronavirus infection as a pandemic in 2020. The started Wuhan, China, and spread rapidly all over world. CT scan has been used an important diagnostic method detection of suspicious patients. One uncommon complications disease 2019 (COVID-19) is pneumothorax.A 47-year-old smoker male with COVID-19 diagnosis, good general condition no respiratory complaint, complicated by pneumothorax. He refused hospitalization. After educating him about red flags quarantine...
