We aimed to analyze the prognostic power of CT-based radiomics models using data 14,339 COVID-19 patients.
Radiation therapy (RT), commonly used in cancer management, has been considered as one of the potential treatments for COVID-19 pneumonia. Here, we present results pilot trial evaluating low-dose whole-lung irradiation (LD-WLI) patients with pneumonia.Ten moderate pneumonia were treated LD-WLI a single fraction 0.5 or 1.0 Gy along national protocol. The primary endpoint was an improvement Spo2. secondary endpoints number days hospital/intensive care unit stay, intubations after RT, 28-day...
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 Background: Consciousness during surgical procedure is associated with adverse psychological effects and postoperative complications. The aim of this study to evaluate the depth anesthesia using brain function index (BFI) among patients undergoing elective laparotomy. Materials methods: In cross-sectional study, 256 referred (XXX) for laparotomy were included. BFI values published studies used measure in response propofol, atracurium propofol induction: deeply anesthetized...
Purpose: Novel coronavirus disease (COVID-19) is the current global concern. Radiotherapy (RT), commonly employed in cancer management, has been considered one of potential treatments for COVID-19 pneumonia. Here, we present final report pilot trial evaluating efficacy and safety low-dose whole-lung irradiation (LD-WLI) patients with Methods Materials: We enrolled moderate pneumonia who were older than 60 years. Participants treated LD-WLI a single fraction 0.5 or 1.0Gy along national...
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...
Our study discusses the probable etiologies and characteristics of pulmonary cavities in post-COVID-19 patients. A cavity is a late complication disease, yet it has led to multiple referrals our tertiary hospital Tehran, Iran.
The coronavirus disease 2019 (COVID-19) is associated with a variety of physical and emotional disorders, subsequently lower Quality Life (QOL). This study aimed to investigate the effect 2-week exercise-based pulmonary rehabilitation on clinical characteristics QOL severe COVID-19 patients after discharge from intensive care unit (ICU).In this quasi-experimental study, eligible cases, who had survived were discharged ICU selected using convenience sampling method. O2 saturation (SpO2),...
Abstract Objectives: The COVID-19 outbreak is affecting people worldwide. Most of the infected patients suffering from respiratory involvement that may progress to acute distress syndrome. This pilot study aimed evaluate clinical efficacy low-dose whole-lung radiotherapy in with pneumonia. Methods: In this trial, done Iran, we enrolled who were older than 60 years and hospitalized receive supplementary oxygen for their documented Participants treated irradiation a single fraction 0.5 Gy plus...
In this study, we assessed the clinical effect of inhaled verapamil on hospitalized COPD patients in a randomized and double-blind study.COPD randomly received 10 mg or 4 cc nebulized distilled water (DW) as placebo.Twenty enrolled each group with no difference baseline characteristics. Mean age was 64.95 ± 8.9 66.9 10.74 years control group; respectively, (P > 0.05). The mean dyspnea score 6.4 1.2 6.2 1.8 group, respectively decreased to 4.9 1.3 5.7 after intervention. change significantly...
Objectives: Thalassemia major (TM) is one of the most common blood disorders with a high mortality rate due to cardiovascular disease. Vitamin D deficiency has been suggested implicate in cardiac abnormalities. In this prospective study, we aimed investigate relationship between serum levels vitamin and tissue Doppler (TD) echocardiographic indices thalassemia patients. Methods: A total 81 TM patients, including 56 females 25 males, mean age 27.5± 6.8 years, were enrolled consecutively....
Background: Patients with severe COVID-19 experience various respiratory complications, which can have potential long-term effects. Objectives: This study investigates the pulmonary consequences of and their relationship severity lung involvement. Methods: All patients who survived in ICU were selected for study. A radiologist reviewed chest CT scans, categorized based on total score (TSS) into two groups: Group (TSS ≤ 7) B > 7). followed up after three months a scan, spirometry, SpO2...
Background: Pneumomediastinum (PM), the presence of air in mediastinum, is a rare condition. Severe COVID-19 patients are at an increased risk for PM and subcutaneous emphysema (SCE) due to alveolar rupture from diffuse lung injury. Despite prevalence patients, optimal treatment approach remains debated. Objectives: This study investigated prevalence, outcomes, associated factors SCE patients. Methods: In this retrospective cohort study, aged 18 - 80 with positive PCR test chest CT scan...

Single pregnant women gestational age over 37 weeks Candidate for referred to in, Patients with consent participate project, 18 over, Weeks–41 weeks, single, ASA class I & II are...
Efforts to control the COVID-19 pandemic are still on. This study aimed evaluate effect of sofosbuvir on length hospital stay and complications in cases with moderate severity.This randomized clinical trial was done cases, who were admitted Shohadaye Tajrish Hospital, Tehran, Iran, from 4/2021 9/2021. Eligible patients randomly allocated into two groups intervention (sofosbuvir) control, their outcomes compared regarding complications.100 divided 50 patients, as groups. The mean age 50.56 ±...
Waldenstrom macroglobulinemia (WM), a rare malignant disorder, occurs as result of abnormal proliferation lymphocytes that produce immunoglobulin M. In cases, WM complicates by type I cryoglobulinemia. Type cryoglobulinemia usually presents with cutaneous manifestations such Raynaud's phenomenon, purpura, necrosis, and gangrene. Various medical conditions, including thrombotic events, rheumatologic disorders, malignancies, may present skin discoloration necrosis. Patients suffering from...
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,...
Abstract Introduction : Despite the improvement in COVID-19 therapeutic management mortality of mechanically ventilated patients remains high. In this study, we determined risk factors these cases.
