The endocrine consequences of weight loss by bariatric surgery (BS) and caloric restriction are not fully understood but contribute to variable improvements in insulin sensitivity and cardiometabolic health. This study compared changes in insulin sensitivity and plasma concentrations of gut peptides 8 weeks and 1 year after BS and a low-calorie diet (LCD). Nineteen female patients with obesity self-selected BS (gastric bypass [n = 5] or sleeve gastrectomy [n = 7]) or LCD (n = 7) in this parallel-arm, prospective observational study.

- The study addresses the lack of resources for medical students focusing on social determinants of health (SDH) in pediatrics by developing a case-based curriculum for third-year medical students during their pediatric clerkship.
- The curriculum consisted of four brief educational segments and was evaluated through voluntary pre- and post-surveys assessing knowledge, skills, and case analysis related to SDH.
- Results showed significant improvements in students' understanding of SDH and their ability to formulate relevant questions regarding the impact of these determinants on pediatric patients' health.
Objective: The objective of this study was to examine the changes in adipose tissue lipolytic capacity and insulin signaling in response to shortened sleep duration (SSD) in postmenopausal women.
Methods: Adipose tissue from a randomized crossover study of nine healthy postmenopausal women (mean [SD], age: 59 [4] years; BMI: 28.0 [2.
Purpose: There has been mounting interest in understanding the impact of financial toxicity (FT) in various cancer types; however, it remains poorly understood and understudied within neuro-oncology-especially as it relates to neurosurgical components of patient care.
Methods: Retrospective, single-center study of patients who underwent craniotomy for resection of glioblastoma from 2020 to 2022. OIBEE™ (Austin, Texas) software was queried to identify the subset of these patients who had a bad debt charged to their account.
Article Synopsis
- The study aimed to explore whether indoor activities could help preschoolers achieve moderate-to-vigorous physical activity (MVPA) and compare how different accelerometer placements measure this activity.
- Thirty-five preschoolers participated in six different activities, and their MVPA was monitored through direct observation and accelerometers placed on the ankle, waist, and wrist.
- Results indicated that activities like balloon/bubbles, cycling, and circuits were effective in promoting MVPA, while others like dancing and cleaning up were less effective; parent and child feedback suggested that most activities were feasible and acceptable.
Objectives: There is a link between inflammatory bowel disease (IBD) and poor sleep quality that is presumed to be multifactorial. The purpose of this study was to identify factors that impact sleep quality in this group including clinical disease activity, depression, anxiety, quality of life, and disordered social media use through questionnaires.
Methods: This prospective study analyzed sleep quality in adolescent patients ages 13 to 18 with a diagnosis of IBD using objective data from wrist actigraphy and subjective report from the Pittsburgh Sleep Quality Index (PSQI).

July 2024
Context: Weight gain and sleep restriction both reduce insulin sensitivity. However, it is not known if sleep duration alters glucose metabolism in response to overfeeding.
Objective: To examine the effect of sleep duration on overfeeding-mediated alterations in carbohydrate metabolism and insulin sensitivity.
Aim: Type 1 diabetes results from autoimmune events influenced by environmental variables, including changes in diet. This study investigated how feeding refined versus unrefined (aka 'chow') diets affects the onset and progression of hyperglycaemia in non-obese diabetic (NOD) mice.
Methods: Female NOD mice were fed either unrefined diets or matched refined low- and high-fat diets.
Obstructive sleep apnea (OSA) is associated with increased risk for diabetes, and standard treatment with positive airway pressure (PAP) device shows inconsistent effects on glucose metabolism. Metformin is known to treat and prevent diabetes, but its effects on skeletal muscle mitochondrial function are not completely understood. Here, we evaluate the effects of metformin on glucose metabolism and skeletal muscle mitochondrial function in patients with OSA.

- Family-based behavioral treatment (FBT) is an effective method for reducing obesity in children, but access is often limited, which led to this study comparing FBT combined with enhanced standard of care (eSOC) against eSOC alone.
- The trial involved children aged 6-15 with obesity and their caregivers, assessing outcomes over 12 months through regular health coaching and guidelines-based treatment approaches.
- The results aim to provide insights into the effectiveness of these interventions in primary care settings, focusing on changes in child weight, parent weight, psychosocial factors, and obesity-related risks.
Background: Food insecurity is a risk factor for multiple chronic diseases, including obesity. Importantly, both food insecurity and obesity are more prevalent in African American women than in other groups. Furthermore, food insecurity is considered a cyclic phenomenon, with episodes of food adequacy (ie, enough food to eat) and food shortage (ie, not enough food to eat).

Methods: Child (n = 37) weight and height were measured in person by a trained data assessor. These were compared with measurements taken remotely by the child's parent with live videoconferencing observation by a study data assessor.
Background: The commercial application Openfit allows for automatic identification and quantification of food intake through short video capture without a physical reference marker. There are no known peer-reviewed publications on the validity of this Nutrition Artificial Intelligence (AI).
Objectives: To test the validity of Openfit to identify food automatically and semiautomatically (with user correction), test the validity of Openfit at quantifying energy intake (kcal) automatically and semiautomatically, and assess satisfaction and usability of Openfit.
Doula care improves maternal care, yet barriers exist to incorporating doula care. The purpose of this study was to evaluate interest and barriers to doula care. Overall, 508 women, 26-35 years of age (54.

Methods: This cross-sectional study utilized baseline data from the Translational Investigation of Growth and Everyday Routines in Kids (TIGER Kids) study.
Background: Dementia, a growing concern among the elderly, has an increased poor postoperative outcome that goes unrecognized by many. Our study aims to establish if dementia plays a role in the outcomes of head and neck cancer patients that undergo resections.
Methods: We queried the National Inpatient Sample (NIS) database from 2016 to 2019 with a primary diagnosis of head and neck cancer who underwent surgical resection.
Article Synopsis
- Insulin is released in rhythmic pulses from pancreatic beta-cells to regulate blood glucose levels, but in type 2 diabetes, this process becomes irregular, especially in certain populations such as American Indians and Native Alaskans who show decreased beta-cell function and higher diabetes rates.
- A study reviewed metabolic outcomes in 10 Native Americans after six months of intravenous hormone therapy, reporting significant reductions in markers like hemoglobin A1C and fasting glucose levels.
- The findings suggest that physiologic hormone administration could potentially improve metabolic syndrome metrics, indicating a need for further research through randomized controlled trials.
Soybean products have nutrients, dietary fiber, and phytoalexins beneficial for cardiovascular and overall health. Despite their high consumption in Asian populations, their safety in Western diets is debated. We conducted a dose-escalating clinical trial of the safety and tolerability of soybean products in eight older adults (70-85 years) with obesity.
