Dietary Fat Modulation of Gut Microbiota and Impact on Regulatory Pathways Controlling Food Intake.

Obesity is a multifactorial disease that continues to increase in prevalence worldwide. Emerging evidence has shown that the development of obesity may be influenced by taxonomic shifts in gut microbiota in response to the consumption of dietary fats. Further, these alterations in gut microbiota have been shown to promote important changes in satiation signals including gut hormones (leptin, ghrelin, GLP-1, peptide YY and CCK) and orexigenic and anorexigenic neuropeptides (AgRP, NPY, POMC, CART) that influence hyperphagia and therefore obesity. In this review, we highlight mechanisms by which gut microbiota can influence these satiation signals both locally in the gastrointestinal tract and via microbiota-gut-brain communication. Then, we describe the effects of dietary interventions and associated changes in gut microbiota on satiety signals through microbiota-dependent mechanisms. Lastly, we present microbiota optimizing therapies including prebiotics, probiotics, synbiotics and weight loss surgery that can help restore beneficial gut microbiota by enhancing satiety signals to reduce hyperphagia and subsequent obesity. Overall, a better understanding of the mechanisms by which dietary fats induce taxonomical shifts in gut microbiota and their impact on satiation signaling pathways will help develop more targeted therapeutic interventions in delaying the onset of obesity and in furthering its treatment.

Do Diet and Dietary Supplements Mitigate Clinical Outcomes in COVID-19?

The coronavirus disease 2019 (COVID-19) has caused a pandemic and upheaval that health authorities and citizens around the globe are still grappling with to this day. While public health measures, vaccine development, and new therapeutics have made great strides in understanding and managing the pandemic, there has been an increasing focus on the potential roles of diet and supplementation in disease prevention and adjuvant treatment. In the literature, the impact of nutrition on other respiratory illnesses, including the common cold, pneumonia, and influenza, has been widely demonstrated in both animal and human models. However, there is much less research on the impact related to COVID-19. The present study discusses the potential uses of diets, vitamins, and supplements, including the Mediterranean diet, glutathione, zinc, and traditional Chinese medicine, in the prevention of infection and severe illness. The evidence demonstrating the efficacy of diet supplementation on infection risk, disease duration, severity, and recovery is mixed and inconsistent. More clinical trials are necessary in order to clearly demonstrate the contribution of nutrition and to guide potential therapeutic protocols.

Chronic pancreatitis changes in high-risk individuals for pancreatic ductal adenocarcinoma.

BACKGROUND AND AIMS: Pancreatic intraepithelial neoplasia is associated with chronic pancreatitis (CP) changes on EUS. The objective of this study was to determine whether CP changes were more common in high-risk individuals (HRIs) than in control subjects and whether these changes differed among higher-risk subsets of HRIs. METHODS: HRIs and control subjects were identified from an endoscopy database. HRIs were defined as having predisposing mutations or a family history (FH) of pancreatic ductal adenocarcinoma. HRIs were classified as vHRIs who met Cancer of the Pancreas Screening (CAPS) criteria for high risk and mHRIs who did not. Multivariable logistic regression was used to adjust for confounders and CP risk factors. RESULTS: Sixty-five HRIs (44 vHRIs, 21 mHRIs) and 118 control subjects were included. HRIs were included for FH (25), Lynch syndrome (5), Peutz-Jeghers syndrome (2), and mutations in BRCA1/2 (26), PALB2 (3), ATM (3), and CDKN2A (1). After adjustment for relevant variables, HRIs were 16 times more likely to exhibit 3 or more CP changes than control subjects (95% confidence interval, 2.6-97.0; P = .003). HRIs were also more likely to have hypoechoic foci (odds ratio, 8.0; 95% confidence interval, 1.9-32.9; P = .004). vHRIs and mHRIs did not differ in frequency of 3 or more CP changes on EUS. CONCLUSIONS: HRIs were more likely to exhibit CP changes and hypoechoic foci on EUS compared with control subjects. HRIs with these findings may require closer surveillance. HRIs who did or did not meet CAPS criteria did not differ with regard to CP findings, supporting a more inclusive approach to screening.

An evaluation of two interventions to enhance patient-physician communication using the observer OPTION5 measure of shared decision making.

OBJECTIVE: Evaluate interventions to enhance patient-physician communication and shared decision making (SDM). METHODS: We used Observer OPTION5 to evaluate primary care visits within a cluster randomized controlled trial in a California delivery organization. Trial interventions included Open Communication (OpenComm), combining patient activation and physician coaching, and AskShareKnow, a patient activation tool, and were compared to a usual care arm. Scores were analyzed with descriptive statistics and generalized estimating equation analysis for 40 visits containing 200 decision topics. RESULTS: The mean overall OPTION5 score was 26.5 out of 100 (s.d.=15.2). Compared to visits in the usual care arm, OpenComm visits had higher mean item scores (0-4 scale) for eliciting (mean=1.0 vs 0.8) and integrating patient preferences (mean=1.0 vs 0.8). OpenComm and AskShareKnow visits had higher scores for presenting options (mean=1.5, 1.5 vs 1.3). AskShareKnow visits had higher scores for discussing pros/cons (mean=1.5 vs 1.1). Lower patient education attainment was associated with lower scores. CONCLUSIONS: OpenComm and AskShareKnow were associated with improved SDM relative to usual care. PRACTICE IMPLICATIONS: Results suggest targeting patient and physician behaviors promotes SDM better than patient activation only. Improving SDM for less educated patients is crucial.

Provider Perspectives on Advance Care Planning Documentation in the Electronic Health Record: The Experience of Primary Care Providers and Specialists Using Advance Health-Care Directives and Physician Orders for Life-Sustaining Treatment.

CONTEXT: Advance care planning (ACP) is valued by patients and clinicians, yet documenting ACP in an accessible manner is problematic. OBJECTIVES: In order to understand how providers incorporate electronic health record (EHR) ACP documentation into clinical practice, we interviewed providers in primary care and specialty departments about ACP practices (n = 13) and analyzed EHR data on 358 primary care providers (PCPs) and 79 specialists at a large multispecialty group practice. METHODS: Structured interviews were conducted with 13 providers with high and low rates of ACP documentation in primary care, oncology, pulmonology, and cardiology departments. The EHR problem list data on Advance Health Care Directives (AHCDs) and Physician Orders for Life-Sustaining Treatment (POLST) were used to calculate ACP documentation rates. RESULTS: Examining seriously ill patients ≥65 years with no preexisting ACP documentation seen by providers during 2013 to 2014, 88.6% (AHCD) and 91.1% (POLST) of 79 specialists had zero ACP documentations. Of 358 PCPs, 29.1% (AHCD) and 62.3% (POLST) had zero ACP documentations. Interviewed PCPs often believed ACP documentation was beneficial and accessible, while specialists more often did not. Specialists expressed more confusion about documenting ACP, whereas PCPs reported standard clinic workflows. Problems with interoperability between outpatient and inpatient EHR systems and lack of consensus about who should document ACP were sources of variations in practices. CONCLUSION: Results suggest that providers desire standardized workflows for ACP discussion and documentation. New Medicare reimbursement for ACP and an increasing number of quality metrics for ACP are incentives for health-care systems to address barriers to ACP documentation.

Enhancing Shared Decision Making Through Carefully Designed Interventions That Target Patient And Provider Behavior.

Patient-provider communication and shared decision making are essential for primary care delivery and are vital contributors to patient experience and health outcomes. To alleviate communication shortfalls, we designed a novel, multidimensional intervention aimed at nudging both patients and primary care providers to communicate more openly. The intervention was tested against an existing intervention, which focused mainly on changing patients' behaviors, in four primary care clinics involving 26 primary care providers and 300 patients. Study results suggest that compared to usual care, both the novel and existing interventions were associated with better patient reports of how well primary care providers engaged them in shared decision making. Future research should build on the work in this pilot to rigorously examine the comparative effectiveness and scalability of these interventions to improve shared decision making at the point of care.

Using Unlicensed Health Coaches to Improve Care for Insured Patients with Diabetes and Hypertension: Patient and Physician Perspectives on Recruitment and Uptake.

Health coach programs using low-cost unlicensed providers have largely targeted uninsured or underserved populations, raising questions about uptake and effectiveness for insured patients. This observational study evaluated the referral process, uptake, and effectiveness of a health coach program for patients with diabetes and/or hypertension at a multispecialty clinic. Data included appointment observations; interviews with patients, physicians, and health coaches; patient and physician characteristics; and measures of utilization and clinical outcomes. Out of 1313 eligible patients, 308 (23.5%) were referred over a 12-month period and 169 (54.9%) had at least 1 health coach appointment. Although the health coach program did not change patients' biometrics, physicians and patients reported improved care processes and reduced physician workload. Barriers to enrollment included variability in physician referral practices, patient willingness, and scheduling difficulties. Modifications to physician and health coach workflow are needed to determine the program's true effectiveness.
