Introduction: Colorectal cancer (CRC) is among the most common cancers and the prognosis of CRC is highly dependent on stage at diagnosis. Although many cases are diagnosed swiftly, there is still room for improvement.

Aim: We aimed to explore CRC diagnostic pathways, encompassing (1) place of initial contact; (2) associations with symptom presentations, sex, and age with events in the diagnostic process and initial referrals and (3) the general practitioner's (GP's) evaluation of the diagnostic processes.

Article Synopsis
  • Low socioeconomic status can lead to poorer health outcomes and treatment disparities in patients with Inflammatory Bowel Disease (IBD), particularly regarding biologic treatment usage.
  • The study analyzed data from over 37,000 IBD patients in Denmark to investigate the correlation between socioeconomic factors and the timing of biologic treatment initiation.
  • Findings indicated that educational background did not significantly influence treatment timing; however, higher income patients with Crohn's disease received treatment sooner, highlighting the complexity of treatment access even in a universal healthcare system.

Measurement of human flourishing represents a salutogenic approach to epidemiological and behavioral research emphasizing factors contributing to "good lives" rather than pathology. The objective of this study was to translate and psychometrically test the 10-item Flourish Index (FI) and 12-item Secure Flourish Index (SFI) in a convenience sample of Danish adults. A total of 325 participants completed a cross-sectional survey, with 148 of those participants completing the survey a second time (retest).

Article Synopsis
  • The increase in life expectancy and health issues among older patients leads to more ICU admissions, risking their physical and cognitive functions, which can permanently affect their quality of life (QoL).
  • This scoping review seeks to identify key variables related to health outcomes and understand what matters for the QoL of frail elderly patients after ICU discharge.
  • The review will follow Joanna Briggs Institute guidelines, including a thorough search of relevant studies from 2013 to 2023, with careful data extraction and analysis to present the findings in both narrative and table forms, ultimately aiming for publication in a scientific journal.

Research suggests a protective effect of religious service attendance on various health outcomes. However, most research has been done in religious societies, raising the question of whether these associations are also prominent in secular cultures. Here we examine mortality and hospitalisations by religious service attendance among men and women in a secular society.

Aim: Differences in levels of vaccine uptake have emerged across Europe, and this may partly be explained by religious beliefs. Our aim is to study the association between religiosity, measured by prayer frequency, and vaccine hesitancy, and to examine how this association varies across European countries and regions.

Methods: This study was based on 42,583 adults aged 50 years and above from 27 European countries in the Survey of Health, Ageing and Retirement in Europe (SHARE), waves 1-8, and the 2nd SHARE COVID-19 Survey.

Background: Living not just longer, but also cognitively healthier, and more independent lives is essential if European countries are to cope with the financial challenges that the shifting age composition of Europe's population presents. Here we investigate the change in life expectancy (LE) spent with good and poor cognitive function among older adults across Europe.

Methods: LE with good/poor cognitive function was estimated by the Sullivan Method.

It is well recognized that socioeconomic status (SES) is an important determinant of health, but many studies fail to address the possibility of reverse causation. We aim to investigate the reciprocal relationship between trajectories of SES and health, and how these associations differ by sex. We performed a longitudinal study including 29,824 men and 37,263 women aged 50+ participating in at least two consecutive waves of the Survey of Health, Ageing and Retirement in Europe (SHARE).

Relative risk (RR) is a preferred measure for investigating associations in clinical and epidemiological studies with dichotomous outcomes. However, if the outcome of interest is rare, it frequently occurs that no events are observed in one of the comparison groups. In this case, many of the standard methods used to obtain confidence intervals (CIs) for the RRs are not feasible, even in studies with strong statistical evidence of an association.

Aim: International health authorities suggest that individuals aged 65 years and above and people with underlying comorbidities such as hypertension, chronic lung disease, cardiovascular disease, cancer, diabetes, and obesity are at increased risk of severe Coronavirus Disease 2019 (COVID-19); however, the prevalence of risk factors is unknown in many countries. Therefore, we aimed to describe the distribution of these risk factors across Europe.

Subject And Methods: Prevalence of risk factors for severe COVID-19 was identified based on interviews from 73,274 Europeans aged 50+ participating in the Survey of Health, Ageing and Retirement in Europe (SHARE) in 2017.

Much of science, including public health research, focuses on means (averages). The purpose of the present paper is to reinforce the idea that variability matters just as well. At the hand of four examples, we highlight four classes of situations where the conclusion drawn on the basis of the mean alone is qualitatively altered when variability is also considered.

Aim: To examine the magnitude of sex differences in survival from the coronavirus disease 2019 (COVID-19) in Europe across age groups and regions. We hypothesized that men have a higher mortality than women at any given age but that sex differences will decrease with age as only the healthiest men survive to older ages.

Methods: We used population data from the Institut National D'Études Démographiques on cumulative deaths due to COVID-19 from February to June 2020 in 10 European regions: Denmark, Norway, Sweden, The Netherlands, England and Wales, France, Germany, Italy, Spain and Portugal.

Certain migration contexts that may help clarify immigrants' health needs are understudied, including the order in which married individuals migrate. Research shows that men, who are healthier than women across most populations, often migrate to a host country before women. Using Danish register data, we investigate descriptive patterns in the order that married men and women arrive in Denmark, as well as whether migration order is related to overnight hospitalizations.
