Care When It Counts: Establishing Trauma-Sensitive Care as a Preventative Approach for 0–3-Year-Old Children Suffering from Trauma and Chronic Stress
Adverse childhood experiences are an important societal concern. Children aged 0-3 are particularly vulnerable to unpredictable chronic stress due to the critical period for brain development and attachment. Trauma-sensitive care is a preventative approach to reduce the burden of stressful experiences by committing to positive relationships. Professional caregivers are ideally placed to offer trauma-sensitive care; however, earlier research reveals that the tools they need to consciously apply trauma-sensitive care principles are missing. The current study organized living labs (co-creative research method) to present trauma-sensitive care as a preventative approach aimed at children aged 0-3. Two living labs were organized in Belgium and Hungary, where professional caregivers collaborated to create a protocol that offers guidelines on how to implement trauma-sensitive care. The resulting protocol included a theoretical foundation on trauma as well as a translation of these guidelines into practical recommendations. The protocol was evaluated by incorporating it into a training intervention delivered to 100 professional caregivers from childcare organizations across four European countries. The protocol received positive feedback from participants, with results indicating a self-reported increase in knowledge, attitude and practice of trauma-sensitive care principles. We conclude that this trauma-sensitive care protocol is a promising answer to the needs of professional caregivers working with children aged 0-3
Dendritic cells license regulatory B cells to produce IL-10 and mediate suppression of antigen-specific CD8 T cells
Regulatory B cells (Bregs) suppress and reduce autoimmune pathology. However, given the variety of Breg subsets, the role of Bregs in the pathogenesis of type 1 diabetes is still unclear. Here, we dissect this fundamental mechanism. We show that natural protection from type 1 diabetes in nonobese diabetic (NOD) mice is associated with increased numbers of IL-10-producing B cells, while development of type 1 diabetes in NOD mice occurs in animals with compromised IL-10 production by B cells. However, B cells from diabetic mice regain IL-10 function if activated by the innate immune receptor TLR4 and can suppress insulin-specific CD8 T cells in a dendritic cell (DC)-dependent, IL-10-mediated fashion. Suppression of CD8 T cells is reliant on B-cell contact with DCs. This cell contact results in deactivation of DCs, inducing a tolerogenic state, which in turn can regulate pathogenic CD8 T cells. Our findings emphasize the importance of DC–Breg interactions during the development of type 1 diabetes
Decreased expression of heat shock protein 72 in skeletal muscle of patients with type 2 diabetes correlates with insulin resistance
Oxidative stress has been ascribed a role in the pathogenesis of diabetes and its complications, and stress proteins have been shown to protect organisms in vitro and in vivo against oxidative stress. To study the putative role of one of the most abundant cytoprotective stress proteins, inducible cytoplasmic 72-kDa-mass heat shock protein (Hsp-72), in the pathogenesis of diabetes, we measured its mRNA concentration in muscle biopsies from six type 2 diabetic patients and six healthy control subjects (protocol 1) as well as in 12 twin pairs discordant for type 2 diabetes and 12 control subjects undergoing a euglycemic-hyperinsulinemic clamp in combination with indirect calorimetry (protocol 2). The amount of Hsp-72 mRNA in muscle was significantly lower in type 2 diabetic patients than in healthy control subjects (in protocol 1: 5.2 +/- 2.2 vs. 53 +/- 32 million copies of Hsp-72 mRNA/mug total RNA, n = 6, P = 0.0039; in protocol 2: 3.2 +/- 3.3 vs. 43 +/- 31 million copies of Hsp-72 mRNA/mug total RNA, n = 12, P = 0.0001). Hsp-72 mRNA levels were also markedly reduced in the nondiabetic co-twins compared with healthy control subjects (5.8 +/- 5.0 vs. 43 +/- 31, n = 12, P = 0.0001), but they were also statistically significantly different from their diabetic co-twins when the difference between the pairs was compared (P = 0.0280). Heat shock protein mRNA content in muscle of examined patients correlated with the rate of glucose uptake and other measures of insulin-stimulated carbohydrate and lipid metabolism. In conclusion, the finding of decreased levels of Hsp-72 mRNA in skeletal muscle of patients with type 2 diabetes and its relationship with insulin resistance raises the question of whether heat shock proteins are involved in the pathogenesis of skeletal muscle insulin resistance in type 2 diabetes
Trauma-informed care in childcare organisations to support children exposed to child maltreatment: Joint conclusions of four European countries
Trauma-informed care is emerging as a promising good practice to recognise, treat and prevent trauma in young children. The use of trauma-informed care in childcare organisations might have a positive impact on children who suffer from child maltreatment. The current study organised desk research and focus group discussions with professional experts in Latvia, Italy, Hungary and Belgium to assess if trauma-informed care is known, applied or taught. The joint conclusions of the desk research and the focus group discussions demonstrated that childcare professionals currently lack the knowledge, skills and attitude to engage in trauma-informed care. Even though they have ways to prevent and tackle trauma, these ways are often based on gut feeling or experience and are not formalised or explicitly addressed. This lack of conscious knowhow is an issue that possibly leads to underreporting of situations of child maltreatment and a lack of attuned responses to children suffering from child maltreatment. Overall, there were no training initiatives focused on trauma-informed care for childcare professionals, which might explain why these good practices do not reach the sector

CD5 promotes IL-10 production in chronic lymphocytic leukemia B cells through STAT3 and NFAT2 activation.
B lymphocytes from chronic lymphocytic leukemia (CLL) display some CD5 transcripts for CD5 containing the known exon 1 (E1A) and other CD5 transcripts containing the new exon 1 (E1B). These malignant B cells, as well as B cell lines transfected with cDNA for E1A-cd5 or with cDNA for E1B-cd5 produce IL-10, raising the possibility that CD5 participates in the secretion of IL-10. We identified transcription factors involved in this production in CD5(+) B lymphocytes from CLL patients and in E1A-cd5-transfected or E1B-cd5-transfected Jok cells. STAT3 is activated via phosphorylation of serine 727 but also NFAT2 through its translocation into the nucleus. Chromatin immunoprecipitation experiments confirmed the role of STAT3 and allowed the discovery of a role for NFAT2 in IL-10 production. Both transcription factors bind not only to the enhancer of the Il-10 gene but also to the promoter of the Il-5 and Il-13 genes. Furthermore, transfection of B cell lines with E1A-cd5 or E1B-cd5 established that activation of STAT3 and NFAT2 is regulated by CD5. The same holds true for the production of IL-10, IL-5, and IL-13 and the expression of the receptors for these cytokines. This interpretation was confirmed by two experiments. In the first, downregulation of CD5 by small interfering RNAs lowered the production of IL-10. In the second experiment, transfection of the GFP-NFAT2 gene into B lymphocytes induced nuclear translocation of NFAT2 in CD5(+) but not in CD5(-) B cells. Thus, CD5 expression is associated with NFAT2 activity (and mildly STAT3 activity), indicating that CD5 controls IL-10 secretion.Journal ArticleResearch Support, Non-U.S. Gov'tinfo:eu-repo/semantics/publishe
