<p><i>Background</i> Longitudinal biomonitoring studies can provide unique information on how human concentrations change over time, but have so far not been conducted for per- and polyfluoroalkyl substances (PFASs) in a background exposed population.</p> <p> <i>Objectives</i> The objectives of this study were to determine: i) serum PFAS time trends on an individual level; ii) relative ...

Culture-independent molecular techniques and advances in next generation sequencing (NGS) technologies make large-scale epidemiological studies on microbiota feasible. A challenge using NGS is to obtain high reproducibility and repeatability, which is mostly attained through robust amplification. We aimed to assess the reproducibility of saliva microbiota by comparing triplicate samples. The ...

Background - Renal cell carcinoma (RCC) is twice as common among men compared with women, and hormonal factors have been suggested to partially explain this difference. There is currently little evidence on the roles of reproductive and hormonal risk factors in RCC aetiology.<p> <p>Materials & Methods - We investigated associations of age at menarche and age at menopause, pregnancy-related factors, ...

<i>Background</i> - The association between reproductive factors and risk of cutaneous melanoma (CM) is unclear. We investigated this issue in the Norwegian Women and Cancer cohort study.<p> <p><i>Objectives</i> - To examine the association between the reproductive factors age at menarche, menstrual cycle length, parity, age at first and last birth, menopausal status, breastfeeding duration and ...

Following the COVID-19 pandemic, Denmark introduced repeated lockdowns of society, including outreach services and visits from social workers for people living with mental illnesses. Based on ethnographic fieldwork, in this article we explore how people with mental illness react to and manage their lives amid COVID-19 mitigations, focusing on how they experience and negotiate vulnerability at ...

The theory of breast cancer as a <i>child deficiency disease</i> is an <i>inversion of the current paradigm</i>, which considers fullterm pregnancies to be a protective factor and uses nulliparous women as the reference group. Instead, the theory of breast cancer as a child deficiency disease says that women with the highest parity (about 20, which is the limit of human fertility) are those with ...

Several researchers have raised the concern that the cross-sectional association of retrospectively reported childhood adversity with self-reported onset of asthma and chronic bronchitis in adulthood may be confounded, as well as mediated by an individual's mental health. The aim of this study was to assess the effect of retrospectively reported childhood adversity on self-reported onset of asthma ...
