Objective: To study the association between behavioural factors and incidence rates of SARS-CoV-2 infection.
Design: Case-control web-based questionnaire study.
Setting: Questionnaire data were collected in the Capital Region of Denmark in December 2020 when limited restrictions were in place, while the number of daily SARS-CoV-2 cases increased rapidly.
Research Question: Does menopausal hormone therapy (HT) with exogenous oestrogens and progestogens change the use of inhaled anti-asthma medications in women with asthma?
Methods: In a population-based matched cohort study using the Danish registries, we included women with asthma aged 45-65 years from 1 June 1995 to 30 June 2018. We investigated whether HT with oestrogen and/or progestogens was associated with changes in use of inhaled anti-asthma therapies in the 12 months following initiation. We used exposure density matching to match exposed subjects with unexposed subjects on age, household income and level of education.

Objective: Currently effective symptom-based screening of patients suspected of COVID-19 is limited. We aimed to investigate age-related differences in symptom presentations of patients tested positive and negative for SARS-CoV-2.
Design: SETTING: Calls to the medical helpline (1-8-1-3) and emergency number (1-1-2) in Copenhagen, Denmark.
Background: Hormone replacement therapy (HRT) is prescribed to millions of women worldwide. Previous studies have suggested that HRT has both protective and harmful effects in asthma.
Research Question: Is HRT in menopause associated with new development of asthma?
Study Design And Methods: We undertook a nested case-control study based on the Danish registers from June 1, 1995, through December 31, 2018.
Introduction: Patients with obstructive lung diseases are possibly at risk of developing severe outcomes of coronavirus disease 2019 (COVID-19). Therefore, the aim of this study was to determine the risk of severe outcomes of COVID-19 among patients with asthma and COPD.
Methods: We performed a nationwide cohort study of patients with COVID-19 from 1 February to 10 July 2020.
