COVID-19 hospital prevalence as a risk factor for mortality: an observational study of a multistate cohort of 62 hospitals.

Background: The associated mortality with COVID-19 has improved compared with the early pandemic period. The effect of hospital COVID-19 patient prevalence on COVID-19 mortality has not been well studied.

Methods: We analysed data for adults with confirmed SARS-CoV-2 infection admitted to 62 hospitals within a multistate health system over 12 months.

Association of Race With Mortality Among Patients Hospitalized With Coronavirus Disease 2019 (COVID-19) at 92 US Hospitals.

Importance: While current reports suggest that a disproportionate share of US coronavirus disease 2019 (COVID-19) cases and deaths are among Black residents, little information is available regarding how race is associated with in-hospital mortality.

Objective: To evaluate the association of race, adjusting for sociodemographic and clinical factors, on all-cause, in-hospital mortality for patients with COVID-19.

Design, Setting, And Participants: This cohort study included 11 210 adult patients (age ≥18 years) hospitalized with confirmed severe acute respiratory coronavirus 2 (SARS-CoV-2) between February 19, 2020, and May 31, 2020, in 92 hospitals in 12 states: Alabama (6 hospitals), Maryland (1 hospital), Florida (5 hospitals), Illinois (8 hospitals), Indiana (14 hospitals), Kansas (4 hospitals), Michigan (13 hospitals), New York (2 hospitals), Oklahoma (6 hospitals), Tennessee (4 hospitals), Texas (11 hospitals), and Wisconsin (18 hospitals).

Fundamental Epidemiology Terminology and Measures: It Really Is All in the Name.

Epidemiology is the study of how disease is distributed in populations and the factors that influence or determine this distribution. Clinical epidemiology denotes the application of epidemiologic methods to questions relevant to patient care and provides a highly useful set of principles and methods for the design and conduct of quantitative clinical research. Validly analyzing, correctly reporting, and successfully interpreting the findings of a clinical research study often require an understanding of the epidemiologic terms and measures that describe the patterns of association between the exposure of interest (treatment or intervention) and a health outcome (disease).

A retrospective review of swallow dysfunction in patients with severe traumatic brain injury.

In the acute-care setting, it is difficult for clinicians to determine which patients with severe traumatic brain injury will have long-term oropharyngeal dysphagia (>6 weeks) and which patients will begin oral nutrition quickly. Patients frequently remain in the acute-care setting while physicians determine whether to place a percutaneous endoscopic gastrostomy (PEG) tube. To improve the acute-care clinician's ability to predict long-term oropharyngeal dysphagia and subsequent need for PEG tube placement in patients with severe traumatic brain injury [Glascow Coma Scale (GCS) ≤ 8), a novel prediction model was created utilizing clinical information and acute-care swallowing evaluation findings.

Patients labeled with delusions of parasitosis compose a heterogenous group: a retrospective study from a referral center.

Background: There are few diagnostic tools available to the dermatologist to help in the diagnosis of patients with delusions of parasitosis (DOP).

Objective: We sought to find differences in presentation and clinical course between patients who received a final diagnosis of DOP and those who received a final diagnosis of a primary medical condition or other psychiatric disorder.

Methods: We performed a retrospective chart review of patients referred with a diagnosis of DOP.

Hospitalizations Due to Respiratory Syncytial Virus Outside of the Typical Season.

Respiratory Syncytial Virus (RSV) is the most common cause of bronchiolitis and viral lower respiratory tract infections in children. It is associated with annual winter epidemics across the United States, typically October through April. Our objective is to describe the clinical characteristics of children hospitalized outside the typical RSV season and to compare them with those admitted during the season.

Prevalence and predictors of smoking behavior among Vietnamese men living in California.

Vietnamese populations in Vietnam and the United States have a high prevalence of smoking. The associations among behavioral risk factors, acculturation, and smoking among the Vietnamese population living in the United States are not well documented. The present study aimed to identify the factors associated with smoking behavior among Vietnamese men living in Santa Clara County, California.

Occupational injury surveillance among electric utility employees.

Currently, there are only limited injury surveillance data for the electric utility workforce. To address this gap, an Occupational Health Surveillance Database for electric power utilities was established for epidemiologic monitoring and intervention program evaluation. Injury rates varied across utility occupations, such as, managers, line workers, and meter readers, ranging from 0.

Survival among U.S. women with invasive epithelial ovarian cancer.

Objective: Invasive epithelial ovarian cancer is a highly fatal disease, diagnosed at advanced stages when survival is poor. Relatively little is known about the variation in survival across U.S.
