Heart remodeling produced by aortic stenosis promotes cardiomyocyte apoptosis mediated by collagen V imbalance

Cardiac remodeling (CR) is a structural change of the heart due to chronic hemodynamic overload related to changes in both myocyte and extracellular matrix (ECM). We investigated that the imbalance of collagen V promotes cardiomyocyte apoptosis that contributes to heart failure and cell death. Aortic stenosis was induced surgically and male Wistar rats were randomized to 18 weeks (Sham 18?w, n?=?12; AoS 18?w, n?=?12) and severe of heart failure (Sham HF, n?=?12; AoS HF, n?=?12) groups. Functional and structural echocardiogram, immunohistochemistry for Ki-67, TUNEL assay and Immunofluorescence for collagen were performed. Our main results were: (1) Progressive reduction of cardiac functional capacity due to cardiac remodeling with decreased eject fraction in heart failure; (2) Imbalance of collagen deposition with increased, crowded and irregular collagen I in situ expression; (3) Dysregulation of dynamic control of collagen fibers with exposed epitopes of collagen V; (4) Additional apoptosis that are dependent to cardiac injury. The collagen V expression in cardiac remodeling is for the first time described and may be related to additional apoptosis and autoimmune response. Our findings suggest a critical role of collagen V in cardiac remodeling to modulate and promote heart failure and death.     

Training for Direct Support Staff at Group Homes for People with Chronic Mental Illness

For people with chronic mental illness, their support system (including direct support staff at group homes) play a key role in ameliorating exacerbations leading to crisis care. However, little information exists on curriculum or training programs focused on reducing exacerbations while promoting compassionate care. We developed, implemented and evaluated such a program that featured role-playing and animated videos supplemented with limited didactics. During development phase, direct support staff reviewed videos and rated them as depicting realistic situations with high acceptability. During implementation, the 6-week course (at least one staff from six different group homes not involved in the development phase) using a 3-month pre-post design found reductions in total number of incident reports and pre-specified outcomes of recipient right complaints, emergency calls, and psychiatric hospitalizations. The program demonstrated acceptability, improved care and better outcomes on some but not all outcomes. Improved training of direct support staff is possible and has positive outcomes.     

Associations Between Initial Subjective Experiences with Tobacco and Self-Reported Recent Use in Young Adulthood

Background: Youth tobacco use behaviors are predictive of patterns in adulthood and effect long-term health outcomes. Yet, few studies have examined the effect of initial subjective experiences (ISEs) during first tobacco use, which has been found to be an indicator of individuals. sensitivity to nicotine and vulnerability to dependence. Objective: The present study aimed to determine the prevalence of ISEs across a variety of tobacco products, evaluate the factor structure of ISEs by first tobacco product used, and examine the relationship between ISEs and recent (30-day) use of tobacco products across time, using a university sample. Methods: Exploratory factor analyses were conducted to identify latent factors present with respect to items measuring ISEs with tobacco, separately by tobacco product (e.g. cigarettes, cigars, hookah, e-cigarettes). Factor scores for positive and negative ISEs were calculated. Multiple logistic regression analyses were conducted to examine associations between ISEs and recent use of each tobacco product, adjusted for age at first use, sex, race/ethnicity, and cohort. Results: ISEs differ by the first tobacco product used. Associations between factor scores for positive and negative ISEs and recent use were found across a variety of tobacco products. Overall, positive ISEs were more strongly associated with recent use, relative to negative ISEs. Conclusions: Further research is needed to identify genetic and biological pathways and social contexts influencing initial subjective experiences with tobacco use, in efforts to delay the initiation for tobacco use and reduce risk for continued use among young adults.     

The stability of engagement over comprehensive neuropsychological assessment in student athletes diagnosed with sports related concussion

We documented effort stability during neuropsychological (NP) testing examining failure rates on three Performance Validity Tests (PVTs). 65 student athletes, ages 8–21, were evaluated in an outpatient practice, following sports-related concussion over three sessions within 18 months of injury (mean=6 months). 7.7% of student athletes failed PVTs at all three test sessions, 7.7% failed PVTs at two test sessions, and 12.3% failed PVTs at one session; 28% of this sample was sub-optimally engaged for at least one test session, producing invalid neuropsychological data at the time of testing and 72% produced valid neuropsychological data across the comprehensive evaluation.     

Cancer Survivors’ Use of Numerous Information Sources for Cancer-Related Information: Does More Matter?

A large proportion of the 14 million cancer survivors in the USA are actively seeking health information. This study builds on the informed- and shared-decision making literature, examining cancer survivors’ health information seeking behaviors to (1) quantify the number of health information sources used; (2) create a demographic profile of patients who report seeking cancer information from numerous sources versus fewer sources in five areas: cancer information overall, disease/treatment, self-care/management, health services, and work/finances; and (3) examine whether seeking cancer information from numerous sources is associated with self-efficacy, fear of recurrence, perceptions of information seeking difficulty, and resultant patient–provider communication. Data came from a survey of post-treatment cancer survivors (N?=?501) who responded to a mailed questionnaire about health information seeking. Participants were divided into two groups using a median split: those who sought health information from more than five sources (numerous source seekers) and those that sought information from less than five sources (fewer source seekers). Multivariable logistic regression was used to model differential information seeking behaviors and outcomes for numerous versus fewer source seekers. On average, survivors sought cancer-related information from five different sources. Numerous source seekers were more likely to be women, have higher levels of education, and report fewer problems with cancer information-seeking. Overall, numerous source seekers were no more or less likely to discuss information with their providers or bring conflicting information to their providers. Understanding the characteristics, behaviors, and experiences of survivors who seek cancer-related information from numerous sources can contribute to informed decision making and patient-centered care.
