BACKGROUND The effect of respiratory medications on risk of asthma death in the UK was studied using the General Practice Research Database. METHODS A total of 96 258 individuals with a diagnosis of asthma were identified, 43 of whom had died as a result of their asthma. For each case 20 controls were selected. Relative risk (RR) estimates and 95% confidence intervals (CI) were computed for e...

Viruses were shown to be present in the respiratory tract in 200 of 763 cases of the sudden infant death syndrome studied in the nine years 1974-82. Epidemiological and pathological evidence suggested that the distribution of viruses in the sudden infant death syndrome differs between infants aged 3 months or less and those aged over 3 months: the incidence of detection of virus was 14% in the ...

In this country cot death or sudden unexpected death in infancy is the commonest cause of infant death outside the neonatal period. Any theory of its cause must take into account the established facts: it is a condition that occurs most frequently during the winter months-76% of cases occur between October and March, i.e. in 50% of the year, and it also occurs most frequently in babies from the...

Idiopathic pulmonary fibrosis (IPF) is a relentlessly progressive lung disease that commonly results in respiratory failure and death. However, the cause of death in these patients has not previously been fully defined. The current study reviews the clinical records and pathological findings of 42 consecutive patients with IPF who underwent a post mortem at the Mayo Clinic (Rochester, MN, USA) ...

Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) is a new pandemic virus, a global concern, and has threatened human health. This virus binds to the Angiotensin-Converting Enzyme 2 (ACE2) that is expressed on different cells, especially on the alveolar cells. So the virus can enter the lung cells and causes respiratory syndromes. In Coronavirus Disease 2019 (COVID-19)  that is cause...

BACKGROUND Although many studies have linked elevations in tropospheric ozone to adverse health outcomes, the effect of long-term exposure to ozone on air pollution-related mortality remains uncertain. We examined the potential contribution of exposure to ozone to the risk of death from cardiopulmonary causes and specifically to death from respiratory causes. METHODS Data from the study cohor...

introduction: health care providers and health policy managers need updated and valid information regarding causes of death (cod) for development the health care facilities, directing primary prevention, assigning funds, and promoting public health. the major causes of death and its burden have not been yet appropriately identified in iran. although several studies had been carried out in this ...

Background and Objective: Recently, coronavirus has become a major cause of death and hospital admission worldwide. This study was aimed to assess the factors associated with the presentation via ambulance and time to in-hospital death or discharge from the hospital using a multilevel joint modeling approach. Materials and Methods: In this historical cohort study, hospitalized patients with CO...
