Purpose: Cancer patients with pre-existing severe mental disorders (SMD), including moderate to severe depression, bipolar disorder and schizophrenia, have reduced life expectancy and are less likely to receive optimal cancer treatment. The aim of this study is to develop and pilot test a supportive care model, to enhance cancer care in this population.

Methods: The model was developed through three phases.

Article Synopsis
  • Accurate body composition assessment is crucial for diagnosing and tracking childhood obesity, and this study compared bioelectrical impedance analysis (BIA) and dual-energy X-ray absorptiometry (DXA) in this context.
  • The study involved 92 obese children and adolescents (ages 5-17) who participated in a long-term lifestyle intervention, with body composition measured using both BIA and DXA at the beginning and end of the program.
  • Results showed that while BIA is good for monitoring group changes over time in body composition, it may not be as reliable for individual assessments, as it tended to underestimate fat mass and overestimate fat-free mass compared to DXA.

Background/objectives: Carbohydrate counting is recommended to improve glycemic control in type 1 diabetes (T1D), but the most effective educational methods are unclear. Despite its benefits, many individuals struggle with mastering carbohydrate counting, leading to inconsistent use and suboptimal glycemic outcomes. This study aimed to compare the effectiveness of two group-based programs with individual dietary counseling (standard care) for glycemic control.

Childhood obesity is a significant global health issue with complex and multifactorial origins, often beginning before conception and influenced by both maternal and paternal health. The increased prevalence of prepregnancy obesity and gestational diabetes mellitus in women of reproductive age contributes to a heightened risk of metabolic dysfunction in offspring. Current clinical practices often implement lifestyle interventions after the first trimester and have limited success, implying that they miss a critical window for effective metabolic adjustments.

Sphingosine-1-phosphate (S1P) is a ubiquitous lipid mediator, acting via specific G-protein-coupled receptors (GPCR) and intracellularly. Previous work has shown that deletion of S1P lyase caused a chronic elevation of cytosolic [Ca] and enhanced Ca storage in mouse embryonic fibroblasts. Here, we studied the role of sphingosine kinase (SphK)-1 in Ca signaling, using two independently generated EA.

Introduction: Several evaluations of lifestyle interventions for childhood obesity exist; however, follow-up beyond 2 years is necessary to validate the effect. The aim of the present study was to investigate long-term weight development following children participating in one of two pragmatic family-centered lifestyle interventions treating childhood obesity.

Methods: This real-life observational study included Danish children 4-17 years of age classified as having obesity.

Patients with cancer and pre-existing severe mental disorder, which include moderate to severe depression, bipolar disorder and schizophrenia, are known to have reduced life expectancy and are less likely to get recommended cancer treatment. Barriers at patient-, provider- and system level have been identified, e.g.

Background: There are currently limited data regarding the effect of semaglutide 2·4 mg in individuals with obesity and prediabetes in clinical trials. We aimed to assess the efficacy and safety of semaglutide 2·4 mg for weight management and glycaemic control in participants with obesity and prediabetes.

Methods: STEP 10 was a randomised, double-blind, parallel-group, phase 3 trial done across 30 trial sites in Canada, Denmark, Finland, Spain, and the UK and included participants aged 18 years or older with a BMI of 30 kg/m or higher and prediabetes according to UK National Institute for Health and Care Excellence criteria (defined as having at least one of the following at screening: HbA of 6·0-6·4% [42-47 mmol/mol] or fasting plasma glucose [FPG] of 5·5-6·9 mmol/L).

Objective: People with Type 1 diabetes (T1D) face an increased risk of eating disorders/disordered eating (ED/DE), with adolescents being particularly vulnerable. Empirical knowledge on the mechanisms underlying development of ED/DE in T1D is crucial for evolving prevention strategies.

Research Design And Methods: Fourteen semi-structured interviews with adolescent females with T1D and ED/DE between 14 and 18 years were conducted and analyzed using reflexive thematic analysis.

The oral cavity is a habitat for different microorganisms, of which bacteria are best described. Studying different bacterial taxa and their proteins is crucial to understanding their interactions with the host and other microbes. Also, for bacteria with virulence potential, identifying novel antigenic proteins is essential to finding candidates for the development of vaccines.

Background: Clinical guidelines recommend basic carbohydrate counting (BCC), or similar methods to improve carbohydrate estimation skills and to strive for higher consistency in carbohydrate intake potentially improving glycaemic control. However, evidence for this approach in type 2 diabetes (T2D) is limited.

Objective: To examine the efficacy of a structured education program in BCC as add-on to standard dietary care on glycaemic control in individuals with T2D.

Purpose: After Roux-en-Y gastric bypass (RYGB), few patients develop severe complications, which ultimately may require reversal of RYGB. We aimed to examine the effect of reversal of RYGB on symptoms and well-being.

Materials And Methods: Via contact to medical and surgical departments treating patients with RYGB, we identified 18 patients, who had undergone reversal, 2009-2019.

Purpose: In adults, diets rich in protein seem beneficial in relation to satiety, weight loss, and weight management; however, studies investigating dietary protein and weight development in children are scarce and inconsistent. This nonrandomized controlled trial aimed to investigate the effect of a higher protein diet during lifestyle intervention on anthropometry and metabolic biomarkers in children with overweight and obesity.

Methods: Children (n:208) were recruited from two multicomponent lifestyle camps.

Background: Tumor-associated macrophages (TAMs) are associated with unfavorable patient prognosis in many cancer types. However, TAMs are a heterogeneous cell population and subsets have been shown to activate tumor-infiltrating T cells and confer a good patient prognosis. Data on the prognostic value of TAMs in colorectal cancer are conflicting.

Article Synopsis
  • Body mass index (BMI) screening in schools is intended to identify overweight and obesity among children, but its effectiveness in reducing these conditions remains uncertain.
  • A systematic review of studies found that BMI screening followed by reporting to parents did not lead to significant changes in children's BMI or weight-related behaviors.
  • Although screening may temporarily affect body image and promote awareness among parents, there is a lack of effective follow-up interventions that could help manage weight-related issues in children.

Introduction: Obesity is associated with compromised glucose metabolism. Hence, it is of interest to investigate if the lifestyle interventions used in the LIBRA-cohort, which aimed at not only weight loss, but also patient well-being, could also help obese patients improve glucose metabolism by evidence of reduced HbA. The aim of the study was to retrospectively investigate if patients who were referred to a lifestyle intervention for obesity, were able to alter HbA.

Article Synopsis
  • The paper talks about how it's really hard to stop kids who are healthy from becoming overweight.
  • A group in Denmark looked at a lot of research to understand what works and found that many programs aimed at helping kids eat better or be more active didn’t really stop healthy kids from gaining weight.
  • The researchers say we need new and smart ideas to prevent healthy kids from becoming overweight because the current methods aren't effective enough.

Emotional eating seems to emerge during the transition from childhood to adulthood; however, limited research has explored the association between emotional overeating and quality of life (QoL) in children with overweight and obesity. Therefore, the aim of this study was to examine the association between QoL and emotional overeating in a Danish sample of children with overweight and obesity. The present cross-sectional study is based on baseline questionnaire data from a nonrandomized controlled trial.
