Aim: To evaluate nationwide asthma hospitalizations and hospital mortality from the year 2000 to 2010.
Methods: Data from the Health Services Central Administration of the Portuguese Ministry of Health on hospital admissions and hospital mortality in the National Health Service in mainland Portugal, from January 1st 2000 to December 31st 2010, were analysed. Cases with bronchial asthma as a main diagnosis were selected.
Results: We found a mean frequency of asthma hospitalizations of 2.5 / 1000 hospital admissions, 28.1 / 100,000 inhabitants (66.6/100,000 in < 19 years old). The global frequency of hospital admissions decreased 18.6% from 2000 to 2010 (r = -0.85, p = 0.002), and 47.0% in those aged 0 to 2 years old (r = -0.77, p = 0.008). There were 261 hospital deaths attributed to asthma (68.5% > 65 years old), accounting for an in-hospital mortality of 8.0 / 1000 asthma hospitalizations and 2.4 / 1,000,000 inhabitants, with no change throughout the years.
Conclusion: Asthma hospitalization rates have decreased, especially in younger children. Mortality remained unchanged, particularly in the elderly; this might be explained by deficient control in this age group.

Respiratory syncytial virus (RSV) is the leading cause of lower respiratory tract infections in young children. During the COVID-19 pandemic, a significant change in the epidemiology of RSV and other viruses occurred worldwide, leading to a reduction in the circulation of these infectious agents. After the pandemic, the resurgence of seasonal respiratory viruses occurred, but some features of these infections contrast to those registered prior to the pandemic.

Respiratory syncytial virus (RSV) has been recognized as a highly important cause of morbidity and mortality among children and adults. A cross-sectional study at representative sites in Jordan was undertaken to provide an assessment of the epidemiology and health and economic burdens of RSV and influenza infections in Jordan amongst hospitalized children under 5 years old for the period between 15 November 2022 and 14 April 2023. This study involved 1000 patients with a mean age of 17.

: Patients receiving heart transplantation require lifelong immunosuppression and compared to the general population, they have a more than five times higher chance of acquiring COVID-19, and their mortality rates are higher. The aim of the present study was to estimate the epidemiological and clinical characteristics of COVID-19 in heart transplant recipients (HTRs) in Slovenia to estimate the vaccination rate and evaluate possible vaccination-hesitant subgroups. : All SARS-CoV-2-positive HTRs (N = 79) between 1 March 2020 and 31 December 2023 at the Infectious Diseases Department, University Medical Centre Ljubljana, Slovenia, were included retrospectively.
