Background: Sleep duration is associated with BMI and waist circumference. However, less is known about whether sleep duration affects different measurements of obesity differently. Objective: To investigate the association between sleep duration and different measures of obesity. Methods: In this cross‐sectional analysis 1309, Danish, older adults (55% men) completed at least 3 days of wearing a combined accelerometer and heart rate‐monitor for assessing sleep duration (hours/night) within self‐reported usual bedtime. Participants underwent anthropometry and ultrasonography to assess BMI, waist circumference, visceral fat, subcutaneous fat, and fat percentage. Linear regression analyses examined the associations between sleep duration and obesity‐related outcomes. Results: Sleep duration was inversely associated with all obesity‐related outcomes, except visceral‐/subcutaneous‐fat‐ratio. After multivariate adjustment the magnitude of associations became stronger and statistically significant for all outcomes except visceral‐/subcutaneous‐fat‐ratio, and subcutaneous fat in women. The associations with BMI and waist circumference demonstrated the strongest associations, when comparing standardized regression coefficients. Conclusions: Shorter sleep duration were associated with higher obesity across all outcomes except visceral‐/subcutaneous‐fat‐ratio. No specifically salient associations with local or central obesity were observed. Results suggest that poor sleep duration and obesity correlate, however, further research is needed to conclude on beneficial effects of sleep duration regarding health and weight loss.

Background: The study of the intrinsic molecular subtypes of breast cancer has revealed differences among them in terms of prognosis and response to chemotherapy and endocrine therapy. However, the ability of intrinsic subtypes to predict benefit from adjuvant radiotherapy has only been examined in few studies. Methods: Gene expression-based intrinsic subtyping was performed in 228 breast tumors collected from two independent post-mastectomy clinical trials (British Columbia and the Danish Breast Cancer Cooperative Group 82b trials), where pre-menopausal patients with node-positive disease were randomized to adjuvant radiotherapy or not. All patients received adjuvant chemotherapy and a subgroup of patients underwent ovarian ablation. Tumors were classified into intrinsic subtypes: Luminal A, Luminal B, HER2-enriched, Basal-like and Normal-like using the research-based PAM50 classifier. Results: In the British Columbia study, patients treated with radiation had an overall significant lower incidence of locoregional recurrence compared to the controls. For Luminal A tumors the risk of locoregional recurrence was low and was further lowered by adjuvant radiation. These findings were validated in the DBCG 82b study. The individual data from the two cohorts were merged, the hazard ratio (HR) for loco-regional recurrence associated with giving radiation was 0.34 (0.19 to 0.61) overall and 0.12 (0.03 to 0.52) for Luminal A tumors. Conclusions: In both postmastectomy trials, patients with Luminal A tumors turned out to have a significant lower incidence of loco-regional recurrence when randomized to adjuvant radiotherapy, leaving no indication to omit postmastectomy adjuvant radiation in pre-menopausal high-risk patients with Luminal A tumors. It was not possible to evaluate the effect of radiotherapy among the other subtypes because of limited sample sizes. [ABSTRACT FROM AUTHOR]

Aim:To evaluate the long-term prognostic impact of age, local treatment and intrinsic subtypes on the risk of local-regional recurrence (LRR) and breast cancer mortality among low-risk patients. Material and methods:Cohort study with prospectively collected data, balanced five-year age groups, including 514 Danish lymph node negative breast cancer patients diagnosed between 1989 and 1998, treated with mastectomy (N = 320) or breast-conserving therapy (BCT) (N = 194) and without systemic treatment. Intrinsic subtype approximation was performed by combining information on estrogen-, progesterone-, HER2 receptor and Ki67. Results:The majority of the tumors had a luminal subtype: 70% Luminal-A (LumA), 16% Luminal-B (LumB), and 10% Luminal-HER2 + (Lum-HER2+). The distribution of intrinsic subtypes between younger (≤45 years) and older (>45 years) patients was similar. Intrinsic subtypes had no prognostic impact on the 20-year LRR risk, regardless of age. A distinct 20-year mortality pattern was observed among the younger patients: 11% of patients with LumB tumor died of breast cancer within the first five years after primary surgery, 23% of patients with Lum-HER2+ tumor died within a 5–10-year period, whereas patients with LumA tumor died with a constant low rate throughout the 20-year period. After 20 years of follow-up, patients with LumA tumor had breast cancer mortality comparable to that of patients with LumB tumor (20%) and lower than Lum-HER2+ tumor (39%). Among the older patients, no distinct mortality pattern was observed, and the 20-year breast cancer mortality was not associated with intrinsic subtypes. Conclusion:Among low-risk patients, 96% of the tumors were Luminal and the distribution of intrinsic subtypes between younger (≤45 years) and older (>45 years) patients was similar. The observed higher frequency of LRR among younger low-risk BCT patients was not associated intrinsic subtype. The 20-year breast cancer mortality was non-significant for LumA tumors among the older patients, whereas among the younger patients, LumA tumors had a comparable mortality with LumB, but lower than for Lum-HER2 + tumors.

Aims Methods Results Conclusions Type 2 diabetes is linked to psychological distress and a doubled risk of depression. This study aims to characterize individuals with type 2 diabetes experiencing diabetes distress and/or depression in relation to lifestyle and metabolic outcomes.A population‐based survey in 2020 targeted individuals with type 2 diabetes (aged 18–75 years) in the Central Denmark Region. This cross‐sectional study assessed diabetes distress (using Problem‐Area‐in‐Diabetes‐scale) and depression (via hospital diagnosis and prescribed medication) as exposures. Logistic regression, adjusting for potential confounders, compared exposed and non‐exposed groups on lifestyle habits, metabolic factors and medication usage related to cardio‐metabolic risks.Of 18,222 respondents with type 2 diabetes (46% response rate), 11% had depression, 14% had diabetes distress and 4% had both. Compared to those with neither condition, those with depression were more often smokers (OR: 2.0, 95% CI: 1.8; 2.3) and sedentary in leisure time (OR: 2.0, 95% CI: 1.8; 2.2). Diabetes distress was associated with elevated HbA1c (OR: 1.8, 95% CI: 1.5; 2.0) and treatment with insulin (OR: 1.8, 95% CI: 1.6; 2.0). Half with diabetes distress displayed stable blood glucose levels. Those with both conditions had a higher risk of sedentary behaviour (OR: 2.7, 95% CI: 2.3; 3.2), clinical insomnia (OR: 6.5, 95% CI: 5.5; 7.7) and low self‐rated health (OR: 7.5, 95% CI: 6.3; 9.0) than those with either psychological condition in isolation.This study emphasizes the importance of recognizing distinct features and risk factors associated with diabetes distress and depression in individuals with type 2 diabetes. Tailored care strategies for comorbid mental health issues are crucial for comprehensive management. [ABSTRACT FROM AUTHOR]
