Circulating Amino Acid Changes Three Years After Bariatric Surgery.

Background And Objective: Studies using metabolomics to study bariatric surgery have shown that amino acids are one of the most changed groups of metabolites after the intervention. However, the surgery-related variation in individual amino acids, as well as the long-term impact and the differences between the types of surgeries, have been poorly studied. The aim of this study was to investigate the changes in circulating amino acids after three types of bariatric surgery up to 36 months after the intervention.

Premature mortality patterns among American Indians in North Dakota, 2010-2019 (pre-pandemic).

Background: According to the National Center for Health Data, in 2017 American Indians in North Dakota experience the highest age-adjusted mortality rate in the United States. Data shows that the age-adjusted death rate for all North Dakotans has steadily declined since 1979. However, mortality remains high among American Indians in North Dakota.

Measuring Wellness Through Indigenous Partnerships: A Scoping Review.

Indigenous wellness has been defined in varying contexts by diverse Indigenous Peoples. The existing indicators used to measure wellness are often defined from a Western perspective. Despite the rich conceptualizations of Indigenous wellness, there exists a notable gap in how it can be measured in contemporary contexts through an Indigenous lens.

Methods: This was a prospective, nonrandomized multicenter trial.

Study Protocol for the Opioid and Pain Treatment in Indigenous Communities Trial: A Systems Level Intervention for Enhanced Screening and Brief Intervention and Referral for Co-Occurring Chronic Pain and Opioid Use Disorder.

American Indian/Alaska Native (AI/AN) individuals have the highest rates of opioid overdose mortality and chronic pain (CP) compared to other racial/ethnic groups in the United States. These individuals also report higher rates of pain anxiety and pain catastrophizing, which are both associated with poorer outcomes and risk for opioid misuse (OM) and opioid use disorder (OUD) among individuals with CP. Yet, no prior studies have examined rates of comorbid pain and OUD among AI/AN adults.

Micronutrient status 2 years after bariatric surgery: a prospective nutritional assessment.

Background: Among commonly performed bariatric surgeries, biliopancreatic diversion with duodenal switch (BPD-DS) provides greater weight loss than Roux-en-Y gastric bypass (RYGB) or sleeve gastrectomy (SG), with sustained metabolic improvements. However, the risk of long-term nutritional deficiencies due to the hypoabsorptive component of BPD-DS hinders its widespread use.

Objective: The aim of the study was to examine nutritional status over 2 years after BPD-DS, RYGB or SG.

Health and well-being needs of Indigenous adolescents: a protocol for a scoping review of qualitative studies.

Introduction: Improving the health of Indigenous adolescents is central to addressing the health inequities faced by Indigenous peoples. To achieve this, it is critical to understand what is needed from the perspectives of Indigenous adolescents themselves. There have been many qualitative studies that capture the perspectives of Indigenous young people, but synthesis of these has been limited to date.

A comparison of the substance use related risk and protective factor profiles for American Indian and White American youth: a mixed studies review.

Bariatric Surgery Should Be Offered to Active-Duty Military Personnel: a Retrospective Study of the Canadian Armed Forces' Experience.

Purpose: Like most Western armies, obesity affects Canadian Armed Forces (CAF) personnel. Bariatric surgery is an effective treatment for obesity. However, this is not yet accepted for active-duty soldiers in most countries.

Centering culture in the treatment of opioid use disorder with American Indian and Alaska Native Communities: Contributions from a National Collaborative Board.

American Indian/Alaska Native (AI/AN) communities are disproportionally impacted by the opioid overdose epidemic. There remains a dearth of research evaluating methods for effectively implementing treatments for opioid use disorder (OUD) within these communities. We describe proceedings from a 2-day Collaborative Board (CB) meeting tasked with developing an implementation intervention for AI/AN clinical programs to improve the delivery of medications to treat OUD (MOUD).

Neck circumference is a better correlate of insulin resistance markers than other standard anthropometric indices in patients presenting severe obesity.

Background: Previous studies have demonstrated stronger associations between metabolic alterations and neck circumference (NC) than with body mass index (BMI) or waist circumference (WC). However, most of these studies were performed in individuals presenting overweight or mild obesity.

Objective: To determine which adiposity index among BMI, WC, NC and fat mass (FM) can best predict metabolic alterations in men and women presenting severe obesity.

Exploring Clinical Risk Factors for Breast Cancer Among American Indian Women.

Objective: Very little is known about the breast cancer risk profile among American Indian women. Previous research shows that the proportion of American Indian/Alaska Native women with baseline characteristics (commonly known breast cancer risk factors) differs from other ethnicities. This retrospective case control study was designed to the explore the association of these factors among American Indian women with and without breast cancer.

Molecular remodeling of adipose tissue is associated with metabolic recovery after weight loss surgery.

Background: Bariatric surgery is an effective therapy for individuals with severe obesity to achieve sustainable weight loss and to reduce comorbidities. Examining the molecular signature of subcutaneous adipose tissue (SAT) following different types of bariatric surgery may help in gaining further insight into their distinct metabolic impact.

Results: Subjects undergoing biliopancreatic diversion with duodenal switch (BPD-DS) showed a significantly higher percentage of total weight loss than those undergoing gastric bypass or sleeve gastrectomy (RYGB + SG) (41.

Identification of Cancer Related Risk and Protective Factors for American Indian Youth: A Mixed Studies Review.

Introduction: Many causes of cancer related morbidity and mortality can be traced back to childhood behaviors. The culmination of cancer related risk and protective factors impacting the health and wellbeing of American Indian youth is unknown. The aim of this Mixed Studies Review was to identify cancer related risk and protective factors among American Indian youth.

Spontaneous neural activity changes after bariatric surgery: A resting-state fMRI study.

Background: Metabolic disorders associated with obesity could lead to alterations in brain structure and function. Whether these changes can be reversed after weight loss is unclear. Bariatric surgery provides a unique opportunity to address these questions because it induces marked weight loss and metabolic improvements which in turn may impact the brain in a longitudinal fashion.

IGFBP-2 partly mediates the early metabolic improvements caused by bariatric surgery.

Insulin-like growth factor-binding protein (IGFBP)-2 is a circulating biomarker of cardiometabolic health. Here, we report that circulating IGFBP-2 concentrations robustly increase after different bariatric procedures in humans, reaching higher levels after biliopancreatic diversion with duodenal switch (BPD-DS) than after Roux-en-Y gastric bypass (RYGB) and sleeve gastrectomy (SG). This increase is closely associated with insulin sensitization.

Neuroanatomical changes in white and grey matter after sleeve gastrectomy.

Background: MRI studies show that obese adults have reduced grey matter (GM) and white matter (WM) tissue density as well as altered WM integrity. Bariatric surgery can lead to substantial weight loss and improvements in metabolic parameters, but it remains to be examined if it induces structural brain changes. The aim of this study was to characterize GM and WM density changes measured with MRI in a longitudinal setting following sleeve gastrectomy, and to determine whether any changes are related to inflammation and cardiometabolic blood markers.

Bariatric Surgery Rapidly Decreases Cardiac Dietary Fatty Acid Partitioning and Hepatic Insulin Resistance Through Increased Intra-abdominal Adipose Tissue Storage and Reduced Spillover in Type 2 Diabetes.

Reduced storage of dietary fatty acids (DFAs) in abdominal adipose tissues with enhanced cardiac partitioning has been shown in subjects with type 2 diabetes (T2D) and prediabetes. We measured DFA metabolism and organ partitioning using positron emission tomography with oral and intravenous long-chain fatty acid and glucose tracers during a standard liquid meal in 12 obese subjects with T2D before and 8-12 days after bariatric surgery (sleeve gastrectomy or sleeve gastrectomy and biliopancreatic diversion with duodenal switch). Bariatric surgery reduced cardiac DFA uptake from a median (standard uptake value [SUV]) 1.

Visuo-haptic integration in object identification using novel objects.

Although some studies have shown that haptic and visual identification seem to rely on similar processes, few studies have directly compared the two. We investigated haptic and visual object identification by asking participants to learn to recognize (Experiments 1, and 3), or to match (Experiment 2) novel objects that varied only in shape. Participants explored objects haptically, visually, or bimodally, and were then asked to identify objects haptically and/or visually.
