High body mass index (BMI) is associated with development of hematological malignancies (HMs). However, although BMI is a well-established measurement of excess weight, it does not fully reflect body composition and can sometimes misclassify individuals. This study aimed at investigating what body composition measurements had highest association with development of HM. Body composition measurements on 27,557 individuals recorded by healthcare professionals as part of the Malmö Diet and Cancer study conducted in Sweden between 1991-1996 were matched with data from national registers on cancer incidence and causes of death. Cox regression models adjusted for age and sex were used to test the association between one standard deviation increments in body composition measurements and risk of HM. During a median follow-up of 20 years, 564 persons developed an HM. Several body composition measurements were associated with risk of developing an HM, but the strongest association was found for multiple myeloma (MM). Waist circumference (HR 1.31, p = 0.04) and waist-hip ratio (HR 1.61, p = 0.05) had higher risk estimates than BMI (HR 1.18, p = 0.07) for MM. In conclusion, our study shows that measurements of abdominal adiposity better predict the risk of developing HM, particularly MM, compared to BMI.

Social media-based Health Education plus Exercise Program (SHEEP) to improve muscle function among young-old adults with possible sarcopenia in the community: A feasibility study protocol.
PLoS One

Faculty of Biology, School of Health Sciences, Medicine & Health, University of Manchester, Manchester, United Kingdom.
Background: Despite the comparatively high prevalence of possible sarcopenia among young-old adults in the community, there is currently no available and effective social media-based intervention to increase the awareness and change the behavior of the target population to prevent sarcopenia. Using co-design methodology, we developed a multicomponent intervention strategy of health education and exercise for sarcopenia prevention utilizing the TikTok platform.
Objectives: The primary purpose of this study is to examine the feasibility and acceptability of the social media-based intervention to enhance muscle function in community-dwelling young-old adults with possible sarcopenia.
The effects of dietary protein on physical performance and body composition in middle age and older people having type II diabetes mellitus: a randomized pilot study.

Purpose: Protein supplementation has been proposed as an effective dietary strategy for maintaining or increasing skeletal muscle mass and improving physical performance in middle-aged and older adults. Diabetes mellitus exacerbates muscle mass loss, leading to many older adults with type 2 diabetes mellitus (T2DM) experiencing sarcopenia, and vice versa. Our objective was to assess the impact of increased dietary protein intake on muscle mass, strength, physical performance, and the progression of T2DM in middle-aged and older adults diagnosed with this condition.

Background: Research into Alzheimer's Disease (AD) pathomechanisms frequently utilizes animal models with dominant mutations; however, the vast majority (>95%) of AD cases are idiopathic. Animal models with AD risk factors represent an approach with potentially greater translational validity. The predominant genetic risk factor for AD is the Apolipoprotein E ε4 (APOE4) polymorphism, with APOE4 homozygosity conferring approximately 15-fold higher risk relative to the normative APOE3/3 genotype.

Background: Previous studies suggest an association between Alzheimer's disease and carotid artery atherosclerosis. However, the association between atherosclerotic carotid plaque composition and Alzheimer's disease pathology (neuritic plaques and neurofibrillary tangles) has not been explored yet.
Method: Carotid arteries were dissected and the segments with the largest obstruction in the carotid bifurcation, and the common and internal carotid arteries were obtained.

Context: Migraine is a disabling neurological disorder. Diet may be a factor to consider because measures of diet quality have been linked to both frequency and severity of attacks.
Objectives: To investigate the effects of dietary interventions on the clinical symptoms of migraine, quality of life, and body composition of patients with migraine.
