Integrative care: acupuncture based neuromodulation therapy for diabetes and heart failure

The relationship between heart failure and diabetes is intricate and bidirectional. Individuals with diabetes face an elevated risk of developing heart failure due to factors like insulin resistance, chronic inflammation, and metabolic irregularities. Elevated blood sugar levels can harm blood vessels and nerves, culminating in the buildup of fatty deposits in arteries, atherosclerosis, and hypertension, which significantly contribute to heart failure. Furthermore, diabetes can adversely impact the structure and function of the heart muscle, impairing its pumping capacity. Conversely, heart failure can also contribute to the onset of diabetes by disrupting the body’s metabolic processes and amplifying insulin resistance. The complex interaction between these conditions mandates a comprehensive approach to managing individuals with both diabetes and heart failure, underscoring the importance of addressing both aspects for enhanced patient outcomes. Although existing pharmacological treatments are limited and frequently associated with undesirable side effects, acupuncture has established itself as a traditional practice with a legacy. It remains a supplementary option for treating cardiovascular diseases. Heart failure and diabetes are both heavily associated with chronic upregulation of the sympathetic nervous system, which has been identified as a pivotal factor in the progression of disease. Mechanistic interplays such as the attenuation of central nitric oxide signaling may interfere with the production or availability of nitric oxide in key areas of the central nervous system, including the brainstem and hypothalamus. This review will delve into the current understanding of acupuncture on the autonomic nervous system and offer insights into its potential role in the future treatment landscape for diabetes and heart failure

Examining the Effects of an Outpatient Palliative Care Consultation on Symptom Burden, Depression, and Quality of Life in Patients With Symptomatic Heart Failure

BACKGROUND: We conducted this prospective comparative study to examine the feasibility and effectiveness of a palliative care consultation along with standard heart failure care in an outpatient setting regarding symptom burden, depression, and quality of life (QOL). METHODS AND RESULTS: Thirty-six patients (53.6 ± 8.3 years old) were referred for an outpatient palliative care consultation after discharge. Changes in symptom burden, depression, and QOL at 3 months were compared with 36 patients with symptomatic heart failure matched on age, sex, race, and New York Heart Association functional class. Improvements were observed in symptom burden, depression, and QOL in both groups over time (all P <.005), but were more pronounced in patients receiving a palliative care consultation (all P <.035). CONCLUSIONS: A palliative care consultation may reduce symptom burden and depression and enhance QOL in patients with symptomatic heart failure. Larger-scale randomized controlled trials sufficiently powered to assess clinical outcomes are warranted to determine the efficacy of palliative care services in outpatient settings regarding symptom distress, depression, and QOL in patients with symptomatic heart failure

Vibrio cholerae vexH Encodes a Multiple Drug Efflux Pump That Contributes to the Production of Cholera Toxin and the Toxin Co-Regulated Pilus

The resistance-nodulation-division (RND) efflux systems are ubiquitous transporters that function in antimicrobial resistance. Recent studies showed that RND systems were required for virulence factor production in Vibrio cholerae. The V. cholerae genome encodes six RND efflux systems. Three of the RND systems (VexB, VexD, and VexK) were previously shown to be redundant for in vitro resistance to bile acids and detergents. A mutant lacking the VexB, VexD, and VexK RND pumps produced wild-type levels of cholera toxin (CT) and the toxin co-regulated pilus (TCP) and was moderately attenuated for intestinal colonization. In contrast, a RND negative mutant produced significantly reduced amounts of CT and TCP and displayed a severe colonization defect. This suggested that one or more of the three uncharacterized RND efflux systems (i.e. VexF, VexH, and VexM) were required for pathogenesis. In this study, a genetic approach was used to generate a panel of V. cholerae RND efflux pump mutants in order to determine the function of VexH in antimicrobial resistance, virulence factor production, and intestinal colonization. VexH contributed to in vitro antimicrobial resistance and exhibited a broad substrate specificity that was redundant with the VexB, VexD, and VexK RND efflux pumps. These four efflux pumps were responsible for in vitro antimicrobial resistance and were required for virulence factor production and intestinal colonization. Mutation of the VexF and/or VexM efflux pumps did not affect in vitro antimicrobial resistance, but did negatively affect CT and TCP production. Collectively, our results demonstrate that the V. cholerae RND efflux pumps have redundant functions in antimicrobial resistance and virulence factor production. This suggests that the RND efflux systems contribute to V. cholerae pathogenesis by providing the bacterium with protection against antimicrobial compounds that are present in the host and by contributing to the regulated expression of virulence factors

Sex Differences and Autism: Brain Function during Verbal Fluency and Mental Rotation

Autism spectrum conditions (ASC) affect more males than females. This suggests that the neurobiology of autism: 1) may overlap with mechanisms underlying typical sex-differentiation or 2) alternately reflect sex-specificity in how autism is expressed in males and females. Here we used functional magnetic resonance imaging (fMRI) to test these alternate hypotheses. Fifteen men and fourteen women with Asperger syndrome (AS), and sixteen typically developing men and sixteen typically developing women underwent fMRI during performance of mental rotation and verbal fluency tasks. All groups performed the tasks equally well. On the verbal fluency task, despite equivalent task-performance, both males and females with AS showed enhanced activation of left occipitoparietal and inferior prefrontal activity compared to controls. During mental rotation, there was a significant diagnosis-by-sex interaction across occipital, temporal, parietal, middle frontal regions, with greater activation in AS males and typical females compared to AS females and typical males. These findings suggest a complex relationship between autism and sex that is differentially expressed in verbal and visuospatial domains

Pro-HEART — A randomized clinical trial to test the effectiveness of a high protein diet targeting obese individuals with heart failure: Rationale, design and baseline characteristics

There is ample research to support the potential benefits of a high protein diet on clinical outcomes in overweight/obese, diabetic subjects. However, nutritional management of overweight/obese individuals with heart failure (HF) and type 2 diabetes mellitus (DM) or metabolic syndrome (MS) is poorly understood and few clinical guidelines related to nutritional approaches exist for this subgroup. This article describes the design, methods, and baseline characteristics of study participants enrolled in Pro-HEART, a randomized clinical trial to determine the short term and long term effects of a high protein diet (30% protein [~110 g/day], 40% carbohydrates [150 g/day], 30% fat [~50 g/day]) versus a standard protein diet (15% protein [~55 g/day], 55% carbohydrates [~200 g/day], 30% fat [~50 g/day]) on body weight and adiposity, cardiac structure and function, functional status, lipid profile, glycemic control, and quality of life. Between August, 2009 and May, 2013, 61 individuals agreed to participate in the study; 52 (85%) - mean age 58.2 ± 9.8 years; 15.4% Blacks; 57.7% Whites; 19.2% Hispanics; 7.7% Asians; 73.1% male; weight 112.0 ± 22.6 kilograms- were randomized to a 3-month intensive weight management program of either a high protein or standard protein diet; data were collected at baseline, 3 months, and 15 months. This study has the potential to reveal significant details about the role of macronutrients in weight management of overweight/obese individuals with HF and DM or MS

Regional Strain Pattern and Correlation with Cardiac Magnetic Resonance Imaging in Fabry Disease.

BackgroundCardiovascular disease is the most common cause of death among Fabry disease patients, who carry significantly increased risk for heart failure and sudden cardiac death. Echocardiographic strain imaging and cardiac MRI are important clinical tools for early detection of cardiomyopathy before onset of systolic or diastolic dysfunction. However, studies on these imaging modalities are limited among Fabry patients.Aim and objectiveTo evaluate echocardiographic strain pattern and correlation with cardiac MRI in Fabry disease.Materials and methodsWe performed a detailed analysis of global longitudinal strain and correlation with cardiac MRI finding in 9 patients diagnosed with Fabry disease.ResultsDespite normal left ventricular ejection fraction, basal and mid inferior segments are more likely to demonstrate strain abnormalities compared to other regions. Additionally, increased interventricular septal and left ventricular posterior wall thickness are correlated with greater strain abnormalities. Finally, MRI evidence of fibrosis and infiltration are detected among most patients with strain abnormalities, but in some cases, strain imaging were able to detect early evidence of cardiomyopathy even before MRI was fully able to detect the change. Basal and mid inferoseptal segment strain abnormalities are early signs of developing cardiomyopathy among patients with Fabry disease.ConclusionThough cardiac MRIs are critical tools for detection of myocardial infiltration and scarring, these findings may not always be detectable in early phases of the disease. Multiple imaging modalities maybe considered in monitoring and evaluation of cardiomyopathy in Fabry disease
