Laparoscopic Roux-en-Y gastric bypass (RYGB) and sleeve gastrectomy (SG) are common and effective methods to treat severe obesity, but these procedures can adversely influence bone metabolism and areal bone mineral density (aBMD). This was a prospective 24-month single-center interventional two-arm study in 220 women and similarly aged men (median age 40.7 years) with a body mass index (BMI) >38 kg/m(2) after RYGB and SG procedures. Patients were randomized into: 1) an intervention group receiving: 28,000 IU cholecalciferol/wk for 8 weeks before bariatric surgery, 16,000 IU/wk and 1000 mg calciummonocitrate/d after surgery, daily BMI-adjusted protein supplementation and physical exercise (Nordic walking, strength perseverance, and equipment training); 2) a non-intervention group: no preoperative loading, nutritional supplementation, or obligatory physical exercise. At study endpoint, when comparing the intervention group to the non-intervention group, the relative percentage changes of serum levels of sclerostin (12.1% versus 63.8%), cross-linked C-telopeptide (CTX, 82.6% versus 158.3%), 25-OH vitamin D (13.4% versus 18.2%), phosphate (23.7% versus 32%, p < 0.001 for all), procollagen type 1 amino-terminal propeptide (P1NP, 12% versus 41.2%), intact parathyroid hormone (iPTH, -17.3% versus -7.6%), and Dickkopf-1 (-3.9% versus -8.9%, p < 0.05 for all) differed. The decline in lumbar spine, total hip and total body aBMD, changes in BMI, lean body mass (LBM), as well as changes in trabecular bone score (TBS) values (p < 0.005 for all) were less, but significantly, pronounced in the intervention group. We conclude that vitamin D loading and ongoing vitamin D, calcium, and BMI-adjusted protein supplementation in combination with physical exercise decelerates the loss of aBMD and LBM after bariatric surgery. Moreover, the well-known increases of bone turnover markers are less pronounced.

Background: Alzheimer's disease is the most dreaded multifactorial neurological illness for which there is currently no known treatment. Although the exact cause of AD is still unknown, several factors related to lifestyle, genetics, and environment are known to have a significant role in the disease's development. Alzheimer's disease is characterized by neuronal loss, neurofibrillary tangles, and senile plaques.

Fleni, Buenos Aires, Buenos Aires, Argentina.

Background: The LatAm-FINGERS trial marks a pioneering initiative as the first non-pharmacological clinical trial encompassing participants from 12 Latin American countries, including Argentina, Brazil, Bolivia, Chile, Colombia, Costa Rica, Ecuador, Dominican Republic, Mexico, Peru, Puerto Rico, and Uruguay. This initiative represents a significant advancement in promoting inclusivity and diversity in clinical trial recruitment, particularly in underserved populations.

Method: The LatAm-FINGERS trial is a multicenter randomized clinical trial evaluating a lifestyle intervention tailored for the Latin American population.

Background: The effectiveness of multimodal lifestyle interventions to prevent dementia is being validated. Since a relatively long period (∼2 years) is required for manifesting an impact on cognitive function, the exploration of an alternative marker that exhibits changes within a comparatively brief duration, thereby prognosticating future alterations in cognitive function, is needed. The decline in gait function is associated with cognitive impairment and is also a predictor of future cognitive decline.

Background: Irisin is an exercise-induced myokine that elicits beneficial effects of exercise in fat, bone, and the brain. Previous work suggests that extracellular heat shock protein 90a (Hsp90a) mediates irisin-receptor interaction in bone and fat. Despite this, it remains unclear if Hsp90a is necessary for irisin signaling in the brain.

Background: Cognitive training and exercise intervention are suggested for enhancing cognitive functions in people with mild cognitive impairment (MCI). The use of virtual reality (VR) has been applied in cognitive training and exercise intervention in recent decades. However, it is still unclear whether VR-based intervention is a useful means to enhance cognitive functions in people with MCI.
