Background:The mortality risk of coronavirus disease 2019 (COVID-19) is higher in patients with older age, and many elderly are reported to require advanced respiratory support.Methods: We reviewed medical records 98 aged ≥ 65 years who were hospitalized COVID-19 during a regional outbreak Daegu/Gyeongsangbuk-do province Korea.The outcome measures in-hospital the treatment mechanical ventilation (MV) or high-flow nasal cannula (HFNC).Results: The median age was 72 years; 55.1% female.Most...
Background Coronavirus disease 2019 (COVID-19) is a global pandemic that had affected more than eight million people worldwide by June 2020. Given the importance of presence diabetes mellitus (DM) for host immunity, we retrospectively evaluated clinical characteristics and outcomes moderate-to-severe COVID-19 in patients with diabetes. Methods We conducted multi-center observational study 1,082 adult inpatients (aged ≥18 years) who were admitted to one five university hospitals Daegu because...
The fatality rate of patients with coronavirus disease 2019 (COVID-19) varies among countries owing to demographics, patient comorbidities, surge capacity healthcare systems, and the quality medical care. We assessed clinical outcomes COVID-19 during first wave epidemic in Korea.
In 2015, a large outbreak of Middle East respiratory syndrome (MERS) occurred in the Republic Korea. Half cases were associated with tertiary care university hospital.
A reliable, non-invasive diagnostic method is needed for early detection and serial monitoring of cardiotoxicity, a well-known side effect chemotherapy. This study aimed to assess the feasibility T1-mapping cardiac magnetic resonance imaging (CMR) evaluating subclinical myocardial changes in doxorubicin-induced cardiotoxicity rabbit model. Adult male New Zealand White rabbits were injected twice-weekly with doxorubicin subjected CMR on clinical 3T MR system before every 2-4 weeks post-drug...
Decreased staffing at nighttime is associated with worse outcomes in hospitalized patients. Rapid response teams were developed to decrease preventable harm by providing additional critical care resources patients clinical deterioration. We sought determine whether rapid team call frequency suffers from decreased utilization night and how this patient outcomes.Retrospective analysis of a prospectively collected registry database.National database inpatient calls.Index calls occurring on the...
The purpose of this study was to determine the extent air and surface contamination severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) in four health care facilities with hospitalized coronavirus disease 2019 (COVID-19) patients.We investigated environmental rooms eight COVID-19 patients hospitals. Some were negative-pressure rooms, others not. None had undergone aerosol-generating procedures. On days 0, 3, 5, 7 hospitalization, surfaces anterooms swabbed, samples collected 2 m...
Although the lungs are major targets for COVID-19 invasion, other organs—such as kidneys—are also affected. However, renal complications of not yet well explored. This study aimed to identify incidence acute kidney injury (AKI) in patients with and evaluate its impact on patient outcomes. retrospective included 704 who were hospitalized at two hospitals Daegu, Korea from February 19 March 31, 2020. AKI was defined according serum creatinine criteria Kidney Disease: Improving Global Outcomes...
Background Determining the activity of pulmonary tuberculosis on chest radiographs is difficult. Purpose To develop a deep learning model to identify active radiographs. Materials and Methods Chest were retrospectively gathered from multicenter consecutive cohort with who successfully treated between 2011 2017, along normal enrich negative class. The pretreatment posttreatment labeled as positive classes, respectively. A neural network was trained those calculate probability versus healed...
With rice being the main staple crop in Asian countries such as China, Korea and Japan, detection of arsenic (As), an element known to be carcinogenic humans, has been topic high public interest.
BACKGROUND: This study was performed to compare the viral load and kinetics of severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) in saliva with those standard nasopharyngeal/oropharyngeal (NP/OP) swabs. METHODS: Fifteen patients SARS-CoV-2 infection from four hospitals were prospectively enrolled matched samples swabs collected at Day 1 admission every other day till consequently negative for two times. Real-time reverse transcription polymerase chain reaction (rRT-PCR) detect...
The predictors of poor prognosis in patients with coronavirus disease 2019 (COVID-19) using computed tomography (CT) have not been investigated a large cohort. Therefore, the purpose this study was to investigate adverse initial CT features predict COVID-19.
The outbreak of the COVID-19 pandemic is a substantial threat to health all populations worldwide, and old age robust risk factor for poor prognosis infection. To reduce fatality rate infection, further understanding elderly patients with necessary. We aimed investigate prognostic factors in COVID-19. This was multicenter retrospective study. Overall, 340 were enrolled 3 hospitals Daegu, South Korea. Death severe pneumonia requiring oxygen treatment defined as clinical outcomes. Of studied,...
Objective To evaluate clinical effectiveness of regdanvimab, a monoclonal antibody agent for treating coronavirus 2019 (COVID-19). Methods A retrospective cohort study was conducted at two general hospitals during the period December 2020 to May 2021. Mild COVID-19 patients with risk factors disease progression admitted within seven days symptom onset were enrolled and followed until discharge or referral. Multivariate analyses in total propensity score (PS)-matched cohorts. Results 778 mild...
Although several antiviral agents have become available for coronavirus disease 2019 (COVID-19) treatment, oral drugs are still limited. Camostat mesylate, an orally bioavailable serine protease inhibitor, has been used to treat chronic pancreatitis in South Korea, and it vitro inhibitory potential against severe acute respiratory syndrome 2 (SARS-CoV-2). This study was a double-blind, randomized, placebo-controlled, multicenter, phase clinical trial mild moderate COVID-19 patients. We...
