Hubungan Skor Rale Gambaran Foto Toraks Dengan Kadar D-Dimer Pada Pasien Covid-19, Marsa Zaidan, Arifin Arifin, Sulistyani Kusumaningrum, Ratih Tri Kusuma Dewi

Jurnal Penyakit Dalam Indonesia

Introduction. COVID-19 pneumonia caused by SARS-CoV-2 leads to extensive pulmonary infiltrates. The Radiographic Assessment of Lung Edema (RALE) score is a quantitative radiological tool to evaluate the severity of lung lesions. Meanwhile, elevated D-dimer levels reflect coagulation and fibrinolysis activation. This study aimed to analyze the correlation between the initial RALE score on chest radiography and D-dimer levels upon hospital admission.

Methods. An analytical observational study with a cross-sectional design was conducted on hospitalized COVID-19 patients at Dr. Moewardi Hospital, Surakarta, from March to July 2021. A total of 98 patients were selected via simple random sampling based …

Validation Of A Real-Time Pcr Laboratory Developed Test For The Detection Of Pneumocystis Jirovecii In Bronchoalveolar Lavage Samples, Caitlyn Moon

Honors Scholar Theses

Pneumocystis jirovecii is an opportunistic, host-obligate fungal pathogen responsible for causing P. jirovecii pneumonia (PJP) in humans. PJP is treated with trimethoprim-sulfamethoxazole (TMP-SMX), a strong broad-spectrum antibiotic that carries risk of renal and hepatotoxicity. Therefore, rapid diagnosis or exclusion of PJP is crucial to ensure PJP-positive patients receive effective treatment and PJP-negative patients avoid unnecessary antibiotics. Unlike most microorganisms, P. jirovecii cannot be cultured, presenting complications for the typical methods of diagnosing fungal pathogens. Historically, the gold standard for diagnosis was direct microscopic examination with stains such as methenamine silver and calcofluor white, but this diagnostic technique requires highly skilled …

BACKGROUND: High-sensitivity cardiac troponin (hs-cTn) assays performed in the central laboratory have long turnaround times. This study evaluates the clinical performance of a novel bedside point-of-care (POC) hs-cTnI assay (i-STAT® hs-TnI) to aid in the diagnosis of myocardial infarction (MI).

METHODS: A prospective multisite cohort study involving emergency department (ED) patients with symptoms suggestive of acute coronary syndrome was conducted at 28 sites across the United States. Serial whole blood samples were collected at 0-1 h and >1-3 h from ED presentation. Primary outcome was MI or non-MI. Sensitivity, specificity, and negative predictive value (NPV) for MI were calculated with …

Audit Of The Impact Of The Pause In The National Screening Service For Breast Cancer During The Covid-19 Pandemic, Ava Coakley

International Undergraduate Journal of Health Sciences

In Ireland there is a free national screening service for breast cancer called BreastCheck. BreastCheck invites women aged fifty to sixty-nine to have screening mammograms once every two years to detect any densities in their breast mammogram which could indicate breast cancer. If densities are seen on a mammogram a breast core is sampled and sent to a histopathology laboratory where a part of the tissue is examined by a consultant pathologist using a microscope. Further tests can then be performed on this sample if it is diagnosed as breast cancer. Tests include immunohistochemistry and dual in-situ hybridisation (DISH). BreastCheck …

Defining Renal Recovery In Patients With Hepatorenal Syndrome-Acute Kidney Injury: Experience From North American Studies, Muhammad A. Mujtaba, Hussien Elsiesy, Sara Faiz, Syed A.

Jefferson Health - Northeast Papers (formerly Aria Health Papers)

INTRODUCTION: The degree of improvement in serum creatinine (SCr) has previously been suggested as a sensitive indicator of treatment response in patients with hepatorenal syndrome-acute kidney injury (HRS-AKI), while HRS reversal remains the primary endpoint in clinical trials.

METHODS: A total of ≥ 30% SCr improvement was analyzed as an exploratory prespecified endpoint in the CONFIRM trial. In this post hoc analysis, intent-to-treat population data from three Phase 3 studies (OT-0401, REVERSE, and CONFIRM) conducted in North America in patients with HRS-AKI were pooled to assess the incidence of > 30% improvement in SCr and its association with clinical outcomes.

RESULTS: …

Molecular Detection Of Entamoeba Histolytica In Diarrheic Fecal Samples From Patients Attending National Hepatology And Tropical Medicine Research Institute, Azza Hasan Abbas, El Shahat Ahmed Elshahat, Heba Mohamed Abdelglil

Journal of Medicine in Scientific Research

Background: Amoebiasis is a worldwide disease caused by Entamoeba histolytica infection. The true prevalence is unknown due to the difficulty in distinguishing Entamoeba histolytica from non-pathogenic amoebas especially when microscopic diagnosis is performed, to overcome microscopy misidentification. Polymerase Chain Reaction (PCR) assay is necessary as a highly sensitive and specific technique. Objective: To determine the value of Real-Time PCR (RT.PCR) in the diagnosis of Entamoeba histolytica in the stool samples of diarrheic patients attending NHTMI versus microscopy, copro- antigen, and serum antibodies detection techniques. Subjects and Methods: A cross-sectional study was conducted on 150 diarrheic patients. Their stool samples were …
