Specialized High�Protein Oral Nutrition Supplement Improves Home Nutrient Intake of Malnourished Older Adults Without Decreasing Usual Food Intake

Background: Reduced nutrient intake is common in patients after hospitalization, contributing to increased risk for readmissionand mortality. Oral nutrition supplements can improve nutrition status and clinical outcomes, but intake of food is prioritized byclinicians. This study examines the impact of a high-protein oral nutrition supplement (S-ONS) on nutrient intake post discharge. Methods: In a subset of patients (14 S-ONS and 16 placebo) from the NOURISH (Nutrition effect On Unplanned ReadmIssionsand Survival in Hospitalized patients) trial, 24-hour dietary recalls were conducted on 3 randomly selected days during the weeksof 30, 60, and 90 days post discharge. Nutrient intake was estimated using Nutrition Data System for Research software. Adequateenergy and protein intake were dened as 30 kcal/kg/d and 1.2 g/kg/d, respectively. Dietary Reference Intakes (DRIs) were usedfor other nutrients. Results: Less than half of patients met the requirements for energy, protein, and 12 micronutrients from foodintake alone during the study. Energy and protein intakes from food were not diminished relative to placebo. Considering nutrientintake from both food and S-ONS, 50% and 71% of patients receiving S-ONSs met energy and protein goals respectively at 90 days(compared with 29% and 36%, in the placebo group), and 100% met the DRI for total carbohydrate, iron, phosphorus, copper,selenium, thiamin, and riboavin at all time points, all of which were consumed at higher amounts vs placebo. Conclusion: Threemonths of S-ONS consumption increases intake of numerous nutrients without decreasing nutrient intake from food in oldermalnourished adults post discharge

Stressor-Induced Increases in Circulating, but Not Colonic, Cytokines Are Related to Anxiety-like Behavior and Hippocampal Inflammation in a Murine Colitis Model

Stressor exposure increases colonic inflammation. Because inflammation leads to anxiety-like behavior, we tested whether stressor exposure in mice recovering from dextran-sulfate-sodium (DSS)-induced colitis enhances anxiety-like behavior. Mice received 2% DSS for five consecutive days prior to being exposed to a social-disruption (SDR) stressor (or being left undisturbed). After stressor exposure, their behavior was tested and colitis was assessed via histopathology and via inflammatory-cytokine measurement in the serum and colon. Cytokine and chemokine mRNA levels in the colon, mesenteric lymph nodes (MLNs), hippocampus, and amygdala were measured with RT-PCR. SDR increased anxiety-like behaviors, which correlated with serum and hippocampal IL-17A. The stressor also reduced IL-1β, CCL2, and iNOS in the colonic tissue, but increased iNOS, IFNγ, IL-17A, and TNFα in the MLNs. A network analysis indicated that reductions in colonic iNOS were related to elevated MLN iNOS and IFNγ. These inflammatory markers were related to serum and hippocampal IL-17A and associated with anxiety-like behavior. Our data suggest that iNOS may protect against extra-colonic inflammation, and when suppressed during stress it is associated with elevated MLN IFNγ, which may coordinate gut-to-brain inflammation. Our data point to hippocampal IL-17A as a key correlate of anxiety-like behavior

Gut microbiome responds to alteration in female sex hormone status and exacerbates metabolic dysfunction

ABSTRACTWomen are at significantly greater risk of metabolic dysfunction after menopause, which subsequently leads to numerous chronic illnesses. The gut microbiome is associated with obesity and metabolic dysfunction, but its interaction with female sex hormone status and the resulting impact on host metabolism remains unclear. Herein, we characterized inflammatory and metabolic phenotypes as well as the gut microbiome associated with ovariectomy and high-fat diet feeding, compared to gonadal intact and low-fat diet controls. We then performed fecal microbiota transplantation (FMT) using gnotobiotic mice to identify the impact of ovariectomy-associated gut microbiome on inflammatory and metabolic outcomes. We demonstrated that ovariectomy led to greater gastrointestinal permeability and inflammation of the gut and metabolic organs, and that a high-fat diet exacerbated these phenotypes. Ovariectomy also led to alteration of the gut microbiome, including greater fecal β-glucuronidase activity. However, differential changes in the gut microbiome only occurred when fed a low-fat diet, not the high-fat diet. Gnotobiotic mice that received the gut microbiome from ovariectomized mice fed the low-fat diet had greater weight gain and hepatic gene expression related to metabolic dysfunction and inflammation than those that received intact sham control-associated microbiome. These results indicate that the gut microbiome responds to alterations in female sex hormone status and contributes to metabolic dysfunction. Identifying and developing gut microbiome-targeted modulators to regulate sex hormones may be useful therapeutically in remediating menopause-related diseases
