AI Article Synopsis
- The study assessed body fat in nonobese women with prolactinoma treated with dopamine agonists using DXA and examined the relationship between body fat, hormone levels, and clinical factors.
- Women with prolactinoma had similar body fat percentages to control subjects, but those with normal prolactin (PRL) levels showed lower body fat across all evaluated areas.
- The findings suggest that appropriate dopamine agonist treatment can reduce body fat and lower the risk of Metabolic Syndrome in these patients.
Article Abstract
Objectives: To evaluate body fat in nonobese women with prolactinoma treated with dopamine agonists, using whole body dual energy X-ray absorptiometry (DXA) and to correlate DXA results with biochemical data and clinical aspects of the prolactinoma.
Design, Patients And Measurements: A cross-sectional study was performed in two University referral centres. Thirty-one nonobese premenopausal women with prolactinoma were subjected to DXA and blood analysis at clinical evaluation. They were compared with 21 control women of similar age and body mass index (BMI).
Results: Women with prolactinoma treated with dopamine agonists and controls had similar body fat percentages in all sites evaluated with DXA (arms, legs, trunk, android, gynoid and total body). Patients with normal PRL levels at study entry had lower body fat percentages in all sites. In the patient group, arm, leg, truncal, android, gynoid and total body fat were positively associated with PRL levels.
Conclusion: Body fat percentage is similar in nonobese women with prolactinoma and in controls. The lower body fat content in patients with normal PRL levels is likely to be due to the metabolic effects of adequate dopamine receptor type 2 (DR2) activation as a result of regular dopamine agonist treatment. This finding reinforces the importance of the appropriate treatment with dopamine agonists in women with prolactinoma, which, besides normalizing PRL levels, reduces body fat content and the consequent risk of developing Metabolic Syndrome and its complications.

Skeletal muscle oxidative capacity related to intramyocellular lipid in young but not in older individuals.
Appl Physiol Nutr Metab
January 2025
Nagoya University, Graduate School of Education and Human Development, Nagoya, Japan.
Skeletal muscles contain lipids inside and outside cells, namely intramyocellular lipids (IMCL) and extramyocellular lipids (EMCL), respectively; lipids have also been found to be interspersed between these muscles as adipose tissue, namely intermuscular adipose tissue (IMAT). Metabolized IMCL has been recognized as an important substrate for energy production and their metabolism is determined by the muscle oxidative capacity. Therefore, it has been speculated that muscle oxidative capacity is related to muscle lipid content.

This study aims to provide a theoretical foundation for the future management of diabetes at various stages induced by a high-fat diet. Specifically, it seeks to determine the appropriate pharmacological interventions for each phase of diabetes development and the targeted therapeutic directions at different stages of diabetes progression. This investigation employed C57BL6 mice as experimental subjects, successfully establishing an insulin resistance model through a 12-week high-fat diet.

Background: Sarcopenia is a clinical syndrome characterized by the loss of muscle mass and strength. Hormonal changes that occur early in women may influence protein synthesis and promote muscle atrophy, leading to probable sarcopenia, defined as a loss of muscle strength without an obvious decrease in muscle mass. Various types of exercise have already proven effective in treating sarcopenia.

The present study examined factors associated with trunk skeletal muscle thickness (MT, an index for the amount of skeletal muscle) and echo intensity (EI, an index for the content of non-contractile tissue, such as intramuscular adipose tissue) in young Japanese men and women in consideration of habitual dietary intake. Healthy men (n = 26) and women (n = 24) aged 20 to 26 were enrolled. Trunk MT and EI were evaluated using ultrasound imaging at the height of the 3rd lumbar vertebra.

Gestational Weight Gain (GWG) modulates pregnancy outcomes and long-term offspring metabolic health. The 2009 Institute of Medicine (IOM) GWG recommendations have largely been validated in Caucasian and mono-ethnic East Asian cohorts. Asians are at higher metabolic risk at a lower body mass index (BMI), and this has prompted the World Health Organization (WHO) to identify lower BMI cut-offs for risk evaluation amongst Asians.
