Concentrated Grape Powder Consumption Modulates Cholesterol Metabolism and Homeostasis in Healthy Subjects.

Scope: Four weeks' of concentrated grape powder (GP) consumption reduces circulating cholesterol in healthy free-living subjects consuming a low-fiber/low-polyphenol diet. Here, the study aims to investigate the underlying mechanisms for cholesterol reduction by evaluating biomarkers of cholesterol de novo biosynthesis, intestinal absorption, miRNA involved in transcriptional regulation of cholesterol metabolism, as well as cholesterol oxidation.

Methods And Results: Fasting plasma samples collected from 19 healthy free-living subjects at baseline and week 4 of GP consumption are used in this study.

Micronutrient deficiencies in patients with gastrointestinal cancer: To treat or not to treat.

Nutrition supplements are widely used among patients with cancer. The general public perceives supplements as more natural anticancer and antitoxicity agents, and often supplements are used without the knowledge of the treating physician. In the clinical setting, there are concerns that supplements may decrease effectiveness of chemotherapy and/or radiotherapy and, as a result, supplementation is avoided.

Micronutrient Deficiency as a Confounder in Ascertaining the Role of Obesity in Severe COVID-19 Infection.

Food insecurity in the United States has been exacerbated due to the socioeconomic strain of the coronavirus disease 2019 (COVID-19) pandemic. Populations experiencing poverty and, as a consequence, food insecurity in the United States are disproportionately affected by obesity, which was identified early in the pandemic as a major risk factor for increased susceptibility to COVID-19 infection and mortality. Given the focus on obesity and its role in immune dysregulation, it is also important to note the role of micronutrient deficiency, another sequalae of food insecurity.

Effect of Standardized Grape Powder Consumption on the Gut Microbiome of Healthy Subjects: A Pilot Study.

Grapes provide a rich source of polyphenols and fibers. This study aimed to evaluate the effect of the daily consumption of 46 g of whole grape powder, providing the equivalent of two servings of California table grapes, on the gut microbiome and cholesterol/bile acid metabolism in healthy adults. This study included a 4-week standardization to a low-polyphenol diet, followed by 4 weeks of 46 g of grape powder consumption while continuing the low-polyphenol diet.

The Impact of Obesity on SARS-CoV-2 Pandemic Mortality Risk.

The COVID-19 pandemic has uncovered the increased susceptibility of individuals with obesity to infection and severe disease leading to hospitalization and death. Studies in New York City demonstrated that after advanced age, obesity was the most common risk factor leading to severe disease and death from COVID-19. While the connection has been recognized, there has not been a general recognition of the potential mechanisms for this link between excess body fat and mortality from this viral pandemic including respiratory complications and sequelae of increased activation of the immune system.

Association of a Self-Paid Medically Supervised Weight Management Program with Reversal of Obesity-Associated Impaired Fasting Glucose.

Aims: The progression of prediabetes to T2DM can be delayed through diet modification and weight management. However, the intensive lifestyle program is often not covered by medical insurance. This retrospective analysis evaluates the association of a patient self-paid weight management program on an improvement of blood sugar in overweight and obese patients with impaired fasting glucose (IFG).

Weight loss for critical care patient to improve lung transplantation candidacy: A case report.

A 47-year-old male with morbid obesity and progressive pulmonary fibrosis was admitted to the intensive care unit (ICU) with worsening hypoxia and nocturnal ventilator dependence. Due to a significant oxygen requirement, the patient could only safely remain in an acute care setting. Unfortunately, he was not eligible for lung transplantation due to having obesity, a relative contraindication to lung transplantation due to potential for post transplantation complications and increased mortality.

Severe Vitamin A Deficiency After Biliopancreatic Diversion.

Biliopancreatic diversion is a surgical procedure that causes weight loss via volume restriction and malabsorption. It is now rarely performed due to the risk of severe nutritional deficiencies including vitamin A. We report a case of severe vitamin A deficiency due to malabsorption from a biliopancreatic diversion procedure for weight loss.

BIOCHEMICAL CONTROL DURING LONG-TERM FOLLOW-UP OF 230 ADULT PATIENTS WITH CUSHING DISEASE: A MULTICENTER RETROSPECTIVE STUDY.

Objective: Cushing disease (CD) results from excessive exposure to glucocorticoids caused by an adrenocorticotropic hormone-secreting pituitary tumor. Inadequately treated CD is associated with significant morbidity and elevated mortality. Multicenter data on CD patients treated in routine clinical practice are needed to assess treatment outcomes in this rare disorder.

Follow-up intervals in patients with Cushing's disease: recommendations from a panel of experienced pituitary clinicians.

Purpose: Follow-up guidelines are needed to assess quality of care and to ensure best long-term outcomes for patients with Cushing's disease (CD). The purpose of this study was to assess agreement by experts on recommended follow-up intervals for CD patients at different phases in their treatment course.

Methods: The RAND/UCLA modified Delphi process was used to assess expert consensus.

Rate of peripheral glucose change during cognitive testing predicts performance in diabetes mellitus.

Background: The reason for cognitive deterioration in diabetes mellitus (DM) remains unknown. One suggestion is that despite elevated glucose levels, patients with DM generally have difficulty utilizing glucose during cognitive tasks. This assumption was tested in the present study.

Blood glucose levels before and after cognitive testing in diabetes mellitus.

The primary indices of diabetes mellitus (DM), including hemoglobin A1c (HbA1c) and fasting glucose, appear to be only moderately predictive of the cognitive impairments exhibited by patients with DM. There is evidence that in DM the ability to utilize glucose is compromised and the authors hypothesized that this difficulty might be relevant to the study of cognitive function in DM. Thus, the authors examined the relationship between cognitive performance and changes in peripheral glucose from the start to the conclusion of cognitive testing.
