Summary: The existing equations for predicting resting energy expenditure in Chilean women tend to overestimate the values, regardless of age or nutritional status. New equations, incorporating body composition variables, show better adaptation to this population sample by achieving a higher classification percentage within +/- 10% of the measured values.

Summary: The study found that dual endothelin A/B receptor antagonism can increase total REE in overweight/obese individuals. These results suggest that modulation of the endothelin system may represent a novel therapeutic target to increase both resting metabolism and caloric expenditure, enhance weight loss, and reduce CVD risk in seemingly healthy individuals with elevated adiposity.

Summary: The basis of medical nutrition therapy for patients with LC-FAODs is to provide adequate energy to maintain anabolism and prevent catabolism. However, it is unclear if energy expenditure among these patients is similar to the normal population. In a study of 31 subjects with LC-FAODs, their measured resting energy expenditure (REE) and total energy expenditure (TEE) were found to be lower than estimated. Comparison with normal data from NHANES and DRI further supported the conclusion that patients with LC-FAODs have lower energy expenditure than the normal population. Current prediction equations may overestimate energy expenditure for LC-FAOD patients.

Summary: The study found that resting energy expenditure (REE) in pregnant women fluctuated from 14 to 28 weeks gestation and was associated with gestational weight gain (GWG) in a time-varying manner. When REE was fluctuating, estimated energy intake (EI) needs may be overestimated and physical activity (PA) needs may be underestimated, increasing the risk of high GWG in the second trimester.

Summary: Individuals with mild asthma have higher resting energy expenditure (REE) compared to healthy controls, even with similar body weight. Asthmatics also show elevated white blood cell and neutrophil counts, which are correlated with REE. Despite higher REE, asthma patients reported lower calorie and carbohydrate intake compared to controls.

Summary: This study evaluated the effects of hyperthyroidism on energy expenditure, thermogenesis, and body composition. The results showed that energy expenditure decreased during hyperthyroidism, but thermogenesis did not increase. Hyperthyroidism led to increased skin temperature in warm conditions but did not affect core body temperature or skin temperature after cold exposure. Furthermore, weight regain and body composition were not influenced by hyperthyroidism.

Summary: In children and adolescents, obesity does not seem to be related to a decrease in resting energy expenditure (REE). The study found that absolute REE increases with age, but the REE/FFM decreases, with a gender-dependent influence. Interestingly, the effect of obesity on absolute REE is not observed in 8-10 year-olds, where leptin may influence the REE/FFM ratio.

Summary: The study found that hypertensive patients have a higher resting metabolic rate than normotensive patients, along with reduced insulin sensitivity. This increased metabolic rate can be explained by an elevated myocardial oxygen consumption due to an increased resting double product, combined with differences in body composition between hypertensive and normotensive subjects.

Summary: It is uncertain whether aging before late adulthood and menopause are associated with fat-free mass and fat mass-adjusted resting energy expenditure (REEadj). This study found that there is a significant difference in REEadj between middle-aged and younger women, as well as between middle-aged women with different menopausal statuses. The study also demonstrated that menopause may not contribute to the decline in REEadj in women.

Summary: This study examined the relationship between subjectively and objectively measured sleep health composites and heart disease. The results showed that having more sleep health problems was associated with a higher risk of heart disease. Individual sleep dimensions were also associated with heart disease risk. The findings suggest that poor sleep health across multiple dimensions may contribute to heart disease risk among middle-aged adults.

Summary: This study examined the impact of spousal support and strain on insomnia symptoms among older adults, and explored the moderation effect of extramarital social factors. The results showed that spousal strain predicted higher insomnia symptoms 5 years later, while spousal support did not have a significant impact. Moreover, the influence of spouses on sleep was moderated by extramarital factors in nuanced ways. The findings highlight the importance of considering older adults' wider social context when studying the positive and negative effects of marital quality on sleep.

Summary: Depression and antidepressant medications increase the risk of type 2 diabetes. Cambodian-Americans have high rates of both depression and diabetes. This study focuses on a diabetes prevention trial for Cambodian-Americans with depression, where different interventions were used with positive outcomes in reducing HbA1c, depressive symptoms, and inflammation/stress hormones. The findings suggest that cardiometabolic and mental health can be improved simultaneously in immigrant and refugee groups.

Summary: The aim of this study was to examine the relationship between actigraphic nighttime sleep duration and quality and next-day mood in urban adolescents. The results showed that longer sleep duration was associated with lower levels of anger the following day, and higher sleep maintenance efficiency was associated with higher levels of happiness the following day. Additionally, longer average sleep duration was associated with lower levels of anger and loneliness compared to others, but there was no within-person association between sleep duration or efficiency and loneliness.

Summary: This community-based qualitative study identified individual, social, and environmental influences on sleep duration, quality, and timing among Latino pre-adolescents. Factors such as technology use, activity levels, dietary intake, and emotions were found to impact sleep at the individual level. Social-level influences included peer and family interactions, while environmental-level influences included home and neighborhood settings. The COVID-19 pandemic exacerbated some of these factors. It is important to consider multiple levels of influence when developing interventions to improve sleep among Latino pre-adolescents.
