Risk of sarcopenia in women with breast cancer: a comparative analysis of screening tools.

Background: Sarcopenia is characterized by the loss of muscle strength and mass and is associated with poorer clinical outcomes in women with breast cancer. However, no specific tool is capable of assessing the risk of sarcopenia in this population. Therefore, the aim of the present study was to compare the performance of SARC-F, SARC-CalF, and BMI-adjusted SARC-CalF as screening tools for the risk of sarcopenia in women with breast cancer.

Low Serum Vitamin D Levels Are Associated with Reduced Muscle Strength in Women with Breast Cancer.

This study aimed to analyze the association between serum vitamin D levels and MS in women with BC. Observational cross-sectional study carried out with adult women with BC, without metastasis/recurrence, with up to 12 months of diagnosis.

This study aimed to evaluate the association between waist circumference (WC) and imaging measurement of central adiposity according to age group in women with BC. Abdominal adiposity was assessed by WC and VAT, obtained by dual-energy X-ray absorptiometry (DXA).

Quality of life of transgender people under the lens of social determinants of health: a scoping review protocol.

Introduction: There is an urgent need for knowledge about the transgender population to inform the development of clinical protocols and training of health professionals on the unique issues affecting this population. Discussing transgender quality of life (QoL) through the lens of social determinants of health (SDOHs) would enable gender-specific health interventions. Here, we aimed to review the evidence on the QoL of transgender people from an SDOH perspective.

Muscle strength is associated with fracture risk obtained by fracture risk assessment tool (FRAX) in women with breast cancer.

Background: Women with breast cancer are at risk for the development of sarcopenia and occurrence of fractures. The initial and periodic screening of these conditions can prevent the risks of disability, poor quality of life, and death. The present study investigated the association between sarcopenia phenotypes and fracture risk, assessed by the Fracture Risk Assessment Tool (FRAX) in women with breast cancer.

Dietary consumption of selenium inversely associated with osteoporosis in postmenopausal women.

Background: Osteoporosis is a skeletal disease characterized by reduced bone mineral density (BMD), which increases the risk of falls and fractures and reduces mobility. Some nutrients have a well-established role in maintaining bone health and preventing osteoporosis, while selenium (Se) has aroused interest in bone health possibly because of its anti-inflammatory and antioxidant capacity. The aim of this study was to evaluate the association between dietary Se consumption and BMD in postmenopausal women.

Low appendicular skeletal muscle mass index is associated with the anthropometric variables of post-menopausal women.

Background: Skeletal muscle mass is a central component of body composition and its decline is enhanced during aging. We verified the association between the appendicular skeletal muscle mass index (ASMI) with the anthropometric variables, biochemical variables, and lifestyle of postmenopausal women.

Methods: Cross-sectional observational study conducted with postmenopausal women.

Noncoding RNAs, cytokines, and inflammation-related diseases.

Chronic inflammation is involved in the onset and development of many diseases, including obesity, atherosclerosis, type 2 diabetes, osteoarthritis, autoimmune and degenerative diseases, asthma, periodontitis, and cirrhosis. The inflammation process is mediated by chemokines, cytokines, and different inflammatory cells. Although the molecules and mechanisms that regulate this primary defense mechanism are not fully understood, recent findings offer a putative role of noncoding RNAs, especially microRNAs (miRNAs), in the progression and management of the inflammatory response.
