Background: Hospital-based surveillance study to estimate the burden of hospitalizations due to pneumonia in Spain.
Patients And Methods: The national surveillance system for hospital data (Conjunto Mínimo de Datos, CMBD) maintained by the Ministry of Health was used to obtain information concerning hospital discharges for pneumonia for the period January 1, 1995 to December 31, 1996.
Results: There were 109,644 hospitalizations for pneumonia during this period. For the years 1995 and 1996 the incidence of hospitalizations for pneumonia was 162 and 189 cases per 100,000 population, respectively. Persons > or = 65 years accounted for 49.5% of cases. The average length of stay in hospital was 11.2 days and the case-fatality rate was 7.4%.
Conclusion: Each year more than 50,000 persons were hospitalized for pneumonia and approximately 4,000 died.

Wastewater Monitoring During the COVID-19 Pandemic in the Veneto Region, Italy: Longitudinal Observational Study.

Unit of Biostatistics, Epidemiology and Public Health, Department of Cardio-Thoraco-Vascular Sciences and Public Health, University of Padova, Via Loredan 18, Padova, Italy, 39 049 8275384.
Background: As the COVID-19 pandemic has affected populations around the world, there has been substantial interest in wastewater-based epidemiology (WBE) as a tool to monitor the spread of SARS-CoV-2. This study investigates the use of WBE to anticipate COVID-19 trends by analyzing the correlation between viral RNA concentrations in wastewater and reported COVID-19 cases in the Veneto region of Italy.
Objective: We aimed to evaluate the effectiveness of the cumulative sum (CUSUM) control chart method in detecting changes in SARS-CoV-2 concentrations in wastewater and its potential as an early warning system for COVID-19 outbreaks.
Impact of co-infections and immune responses on clinical severity of human adenovirus 3 and 7 infections in hospitalized children with lower respiratory tract infections: a comparative study.

Department of Respiratory Medicine, Children' s Hospital Affiliated to Capital Institute of Pediatrics, Beijing, China.
Background: The pathogenic distribution of co-infections and immunological status of patients infected with human adenovirus serotypes 3 or 7 (HAdV-3 or HAdV-7) were poorly understood.
Methods: This study involved a retrospective analysis of respiratory specimens collected from enrolled children with lower respiratory tract infections (LRTIs), positive for HAdV-3 or HAdV-7 from January 2017 to December 2019. Demographic data, clinical features, laboratory and radiographic findings were compared to delineate the impact of co-infections, and immune responses on clinical severity of HAdV-3 or HAdV-7 infections.
Genetic determinants of COVID-19 severity and mortality: Alu 287 bp polymorphism and , , expression in hospitalized patients.

Departamento de genética, ecologia e evolução, Laboratório de biologia integrativa, Universidade Federal de Minas Gerais, Belo Horizonte, Minas Gerais, Brazil.
Background: The angiotensin-converting enzyme 2 (ACE2) and the transmembrane serine protease 2 (TMPRSS2) are central human molecules in the SARS-CoV-2 virus-host interaction. Evidence indicates that may influence expression. This study aims to determine whether ACE1, ACE2, and TMPRSS2 mRNA expression levels, along with the ACE1 Alu 287 bp polymorphism (rs4646994), contribute to the severity and mortality of COVID-19.

Department of Physical Education, Health & Recreation, National Chiayi University, Chiayi, Taiwan.
Background: For many physical education teachers, being suddenly forced to switch from traditional face-to-face teaching to online teaching without adequate mental preparation posed numerous challenges and difficulties. Therefore, the purpose of this study is to validate the use of distance teaching behavior models for physical education teachers under the influence of the COVID-19 pandemic.
Method: The unified theory of acceptance and use of technology (UTAUT) model was employed to explore the use intention and use behavior of distance teaching.
