Regulatory T cells (Tregs) maintain immune homeostasis by regulating the activation of other immune cells. Preclinical studies show that the infusion of Tregs can promote immunological tolerance to allografts and prevent or cure multiple autoimmune diseases. However, Treg therapy is limited by high numbers of cells required to induce tolerance. In this study, we aimed at improving the in vitro expansion of sort purified mouse Tregs using the CD28 Superagonist (CD28-SA) D665 and comparing it to the conventional expansion using anti-CD3/anti-CD28 Dynabeads®. CD28-SA-stimulated Tregs expanded more than Dynabead®-stimulated Tregs while maintaining their phenotype by expressing the same level of CD4, CD25 and Foxp3. CD28-SA-expanded Tregs produced comparable amounts of IL-10 and TGFβ while showing a slightly superior suppressive capacity compared to Dynabead®-stimulated Tregs. Thus, stimulating murine Tregs with the CD28-SA is a promising alternative since it maintains their suppressive capacity without altering their phenotype and yields a higher fold expansion within 14 days.Our recent trial demonstrated individuals suffering from social anxiety with performance-related concerns who received virtual reality exposure augmented with scopolamine, a cholinergic antagonist, experienced significantly less post-treatment context renewal (CX) than placebo (Craske et al., 2019). The purpose of the present investigation was to determine who specifically benefits from scopolamine by examining hippocampal (HPC) functioning as a moderator of treatment response (Placebo n = 15, SCOP 0.5 mg n = 15, SCOP 0.6 mg n = 15). Skin conductance response to conditional stimulus (SCR-to-CS) termination suggested a dose-response relationship for enhanced HPC functioning individuals, wherein individuals receiving scopolamine demonstrated less fear at CX. In addition, SCR-to-CS onset indicated reduced fear at CX for impaired HPC individuals receiving SCOP 0.5 mg and SCOP 0.6 mg relative to Placebo. Our findings, however, lacked consistency across measures. Scopolamine remains a promising agent and additional research required to further understand its effects.The quality of aged care provided to older people is a concern for all countries globally. This study adopts a novel first-stage discrete choice experiment (DCE) and a second-stage quality rating task to empirically estimate the relative importance of six key aged care quality criteria from more than 10,000 Australian general population sample. The six attributes or characteristics (each with five levels) compose the new measure, Quality of Care Experience (QCE) in aged care that includes 'Respect & Dignity', 'Make Own Decisions', 'Skills & Training (of staff)', 'Health & Wellbeing', 'Social Relationships', and 'Lodging Complaints'. The online survey was conducted between September and October 2019. Preference heterogeneity was evident among respondents. The latent class analysis indicates that those more experienced respondents (i.e. have a better knowledge of Australia's current aged care system or they had a close family member who was receiving aged care services) valued more towards the outcomes of the aged care services whilst the inexperienced respondents valued highly towards the process of the aged care services. A preference weighted scoring algorithm was developed for the QCE measure (on a 0-1 scale whereby 0 = lowest quality and 1 = highest quality) and the corresponding quality thresholds for 'Unacceptable/Poor', 'Satisfactory' and 'High/Very High' quality of care were reported based on the second-stage quality rating questions following each DCE task. The impact of different QCE attributes on the quality ratings was non-linear when considering movements from 'Unacceptable/Poor' to 'Satisfactory', and from 'Satisfactory' to 'High/Very High'. This study provides important insights into the general public's perceptions of the relative importance of key quality of care experience criteria in aged care.Authorities within the field of palliative care frequently espouse that assisted death is - and must remain - separate from palliative care. This fault line, between palliative care and assisted death, has important implications for how we enact end-of-life care, particularly in jurisdictions where assisted death is legal. And yet little is known about how direct-care clinicians providing palliative care navigate this demarcation in everyday practice. DPCPX This qualitative study reports on semi-structured interviews with 22 palliative care nurses from across Canada, where assisted death was legalized in 2016. Although a minority of participants did express categorical opinions around the (non) legitimacy of assisted death as an ethical end-of-life care option, most engaged in an ongoing and sometimes painful process of questioning and self-examination. Their ethical reflections were more nuanced than simply dismissing MAiD as incompatible with palliative care philosophy; yet this idea of incompatibility weighed hesisted death and palliative care.The low rate of help-seeking and high rate of suicide completion among men has prompted public health officials to create suicide prevention campaigns that specifically target men. Drawing from data collected as part of a larger study of fire recovery in a rural county in Northern California, this paper utilizes 68 interviews with fire survivors (24 men and 44 women) and 40 interviews with mental health service providers to examine how rural residents interpret this type of campaign. To track patterns of help-seeking over time, I also draw upon 26 follow-up interviews - 20 with fire survivors (7 men and 13 women) and 6 with service providers - conducted one year after the first wave of interviews. In total, 134 in-depth interviews were conducted. This paper also draws on a secondary data source; I conducted content analysis of an internal Health and Human Services Agency focus group report used in the development of a local male-targeted suicide prevention campaign, Captain Awesome. As I show, male-targeted suicide prevention efforts have little salience in rural communities in which treatment resources are limited and stigma abounds. Perceptions about material conditions - i.e., treatment resources being few and far between - contribute to residents establishing a norm of not seeking help. Rural culture which emphasizes self-sufficiency and independence contributes to a pattern of both men and women repeating a narrative that frames men who seek help as weak. While research has identified women as key drivers for men's physical health maintenance, my research suggests that the same pattern might not hold around mental health maintenance in rural settings. In sum, I argue that male-targeted campaigns have limited resonance and efficacy in rural communities where material conditions and cultural narratives create physical and psychological barriers to accessing to treatment.Research on grandparenting (i.e., caring for grandchildren) and mental health in Asian contexts has been limited, despite the rapid growth of older adults who take care of grandchildren. This study aims to investigate how grandparenting influences depressive symptoms in China. Using the China Health and Retirement Longitudinal Study (2011-2015, N = 4354), we conducted fixed effects regression models to examine the association between various types of grandparenting and depressive symptoms among older adults between the ages of 45 and 80. The results show that for grandparents, providing care to their grandchildren in skipped-generation households (i.e., grandparent-grandchildren families without adult children) is associated with a lower level of depressive symptoms compared to providing no care, after controlling for socioeconomic status, health behaviors, social support, and basic demographic characteristics. Other types of care (i.e., multigenerational household grandparenting, and part-time and full-time noncoresident grandparenting) are not significantly linked to caregiving grandparents' depressive symptoms. Overall, our findings suggest that sociocultural contexts need to be considered in explaining the different mental health implications of grandparenting.
Individuals with schizophrenia exhibit deficits in visual contrast processing, though less is known about how these deficits impact neurocognition and functional outcomes. This study investigated effects of contrast sensitivity (CS) on cognition and capacity for independent living in schizophrenia.
Participants were 58 patients with schizophrenia (n=49) and schizoaffective disorder (n=9). Patients completed a psychophysical paradigm to obtain CS with stimuli consisting of grating patterns of low (0.5 and 1 cycles/degree) and high spatial frequencies (4, 7, 21 cycles/degree). Patients completed the MATRICS Consensus Cognitive Battery and Wechsler Adult Intelligence Scales, Third Edition to assess cognition, and the problem-solving factor of the Independent Living Scales to assess functional capacity. We computed bivariate correlation coefficients for all pairs of variables and tested mediation models with CS to low (CS-LSF) and high spatial frequencies (CS-HSF) as predictors, cognitive measures as mediators, and capacity for independent living as an outcome.
Cognition mediated the relationship between CS and independent living with CS-LSF a stronger predictor than CS-HSF. Mediation effects were strongest for perceptual organization and memory-related domains. In an expanded moderated mediation model, CS-HSF was found to be a significant predictor of independent living through perceptual organization as a mediator and CS-LSF as a moderator of this relationship.
CS relates to functional capacity in schizophrenia through neurocognition. These relationships may inform novel visual remediation interventions.

1) To assess nursing students' evidence-based knowledge on the use of PVCs, and 2) to examine the perception of learning and teaching strategies aimed at this skill.
Insertion and care of Peripheral Venous Catheters (PVCs) are essential skills in undergraduate nursing education. Appropriate knowledge of this skill is crucial to improve clinical practice and patient safety. Therefore, training becomes an enabler for safe practice.
A multi-centre convergent parallel mixed-methods.
A total of 675 second-, third- and fourth-year nursing students from 3 nursing schools took part in the study.
Quantitative data collection used a validated 15-question survey on knowledge of PVC management, and a descriptive and inferential analysis was carried out. Qualitative data were collected via a questionnaire consisting of 4 open-ended questions assessing knowledge, teaching methodologies and scenarios, and points for improvement.
Most participants were female (74.04%), with a mean age of 22.45 (SD=4.65), who had d online training. There is a need to develop programmes that favour the alignment of theory with clinical practice.Aging is an inescapable complex physiological but extendable process, and all cells, including stem cells, are altered over time. Diverse mechanism(s) could modulate stem cell number, their proliferation rate, and promote tissue repair during aging that leads to longevity. However, the factors that could restore aging stem cell potency and would lead to healthy aging are not fully identified. Here we show that maintaining cytosolic Ca2+ levels was essential for modulating stem cells function in aged mesenchymal stem cells (MSCs). Increasing external Ca2+ induced spindle shape stem cell morphology and maintained stem cell surface marker expression in aged bone marrow-derived MSCs. Similarly, stem cell survival and proliferation of aged MSCs was dependent on cytosolic Ca2+ levels. Importantly, Ca2+ entry potentiated cell cycle progression, and stem cell potential was increased in cells incubated with higher external Ca2+. Moreover, blocking Ca2+ entry using SKF 96365, decreased stem cell survival and its proliferation but, treatment with 2-APB did not significantly affected cell proliferation, rather only modulated cell viability.
