Immunization of hypercholesterolemic mice with selected apoB-100 peptide antigens reduces atherosclerosis but the precise immune mediators of athero-protection remain unclear. In this study we show that immunization of apoE (-/-) mice with p210, a 20 amino acid apoB-100 related peptide, reduced aortic atherosclerosis compared with PBS or adjuvant/carrier controls. Immunization with p210 activated CD8+ T cells, reduced dendritic cells (DC) at the site of immunization and within the plaque with an associated reduction in plaque macrophage immunoreactivity. Adoptive transfer of CD8+ T cells from p210 immunized mice recapitulated the athero-protective effect of p210 immunization in naïve, non-immunized mice. CD8+ T cells from p210 immunized mice developed a preferentially higher cytolytic response against p210-loaded dendritic cells in vitro. Although p210 immunization profoundly modulated DCs and cellular immune responses, it did not alter the efficacy of subsequent T cell dependent or independent immune response to other irrelevant antigens. Our data define, for the first time, a role for CD8+ T cells in mediating the athero-protective effects of apoB-100 related peptide immunization in apoE (-/-) mice.
A Family Systems Theory framework can be useful in helping health care providers, and particularly nurses, deliver optimal care to palliative cancer patients and their families and standardize the way research is done by providing an appropriate framework with which to study the family. In addition, the adoption of Family Systems Theory as the standard framework from which to study families in palliative care will provide consistency for future studies that is presently lacking. Finally, nursing interventions to care for the family are suggested based on Family Systems Theory.
Pain requiring treatment is experienced by many cancer patients at the end of life. Family caregivers are often directly implicated in pain management. This article highlights areas of psychosocial concern for family caregivers managing a family member's cancer pain at home as they engage in pain management processes. This article is based on the secondary analysis, guided by interpretive description, of data collected for a grounded theory study that explored the processes used by family caregivers to manage cancer patients' pain in the home. Interviews and field notes from 24 family caregiver interviews were examined to identify areas of family caregiver psychosocial distress. The analysis revealed that family caregivers experienced distress at different phases of the pain management process. Sources of distress for caregivers included feeling as though they were "in a prison" (overwhelmingly responsible), "lambs to slaughter" (unsupported), and "flying blind" (unprepared). In addition, family caregivers expressed distress when witnessing their loved one in pain and when pain crises invoked thoughts of death. In sum, family caregivers managing a loved one's cancer pain at home are at risk for psychosocial distress. This study identified four key sources of distress that can help health care professionals better understand the experiences of these family caregivers and tailor supportive interventions to meet their needs. Knowledge about sources of distress can help healthcare professionals understand the experiences of these family caregivers and tailor supportive interventions to meet their needs.
Emotion regulation (ER) difficulties are a potential common factor underlying the presentation of multiple emotional and behavioral problems in individuals with Autism Spectrum Disorder (ASD). To provide an overview of how ER has been studied in individuals with ASD, we conducted a systematic review of the past 20 years of ER research in the ASD population, using established keywords from the most comprehensive ER literature review of the typically developing population to date. Out of an initial sampling of 305 studies, 32 were eligible for review. We examined the types of methods (self-report, informant report, naturalistic observation/ behavior coding, physiological, and open-ended) and the ER constructs based on Gross and Thompson's modal model (situation selection, situation modification, attention deployment, cognitive change, and response modulation). Studies most often assessed ER using one type of method and from a unidimensional perspective. Across the 32 studies, we documented the types of measures used and found that 38% of studies used self-report, 44% included an informant report measure, 31% included at least one naturalistic observation/behavior coding measure, 13% included at least one physiological measure, and 13% included at least one open-ended measure. Only 25% of studies used more than one method of measurement. The findings of the current review provide the field with an in-depth analysis of various ER measures and how each measure taps into an ER framework. Future research can use this model to examine ER in a multicomponent way and through multiple methods. Autism Res 2014, 7: 629-648 [American Psychiatric Association, 2013], and there is considerable evidence that the majority also struggle with associated emotional problems. For instance, in a population derived cohort of 5-to 16-year-olds, Totsika, Hastings, Emerson, Lancaster, and Berridge [2011] found that 85% of youth with ASD without an intellectual disability (ID) had clinically significant levels of hyperactivity, 74% of emotional problems, and 64% of conduct problems, compared to much lower rates in a typically developing comparison group (19% hyperactivity, 18% emotional problems, and 22% conduct problems). Further, youth with ID and ASD had higher rates of emotional disorders than those with only ID (88% vs. 63% for hyperactivity, 71% vs. 42% for emotional problems, and 65% vs. 46% for conduct problems, respectively). There is also considerable co-occurrence of multiple emotional problems in individuals with ASD. Approximately 40-50% of youth with ASD are estimated to meet criteria for two or more psychiatric disorders, often combining attentional or behavioral problems (e.g. ADHD) with internalizing problems (e.g. anxiety disorder), even after taking into account symptoms that may be related to core ASD sociocommunicative and behavioral symptoms [Leyfer et al., 2006;Simonoff et al., 2008].
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
