Research and Innovation for and with Adolescent Young Carers to Influence Policy and Practice-The European Union Funded "ME-WE" Project.

Young carers are children and adolescents who provide care to other family members or friends, taking over responsibilities that are usually associated with adulthood. There is emerging but still scarce knowledge worldwide about the phenomenon of young carers and the impact of a caring role on their health, social and personal development spheres. This paper provides an overview of the main results from the ME-WE project, which is the first European research and innovation project dedicated to adolescent young carers (AYCs) (15-17 years). The project methods relied on three main activities: (1) a systematization of knowledge (by means of a survey to AYCs, country case studies, Delphi study, literature review); (2) the co-design, implementation and evaluation of a primary prevention intervention addressing AYCs' mental health (by means of Blended Learning Networks and a clinical trial in six European countries); (3) the implementation of knowledge translation actions for dissemination, awareness, advocacy and lobbying (by means of national and international stakeholder networks, as well as traditional and new media). Project results substantially contributed to a better understanding of AYCs' conditions, needs and preferences, defined tailored support intervention (resilient to COVID-19 related restrictions), and significant improvements in national and European policies for AYCs.

Quality of Life of Schoolchildren Living with a Long-Term Sick Parent: The Role of Tasks at Home, Life Circumstances and Social Support.

This study investigates whether there are differences in quality of life-i.e., psychosomatic complaints and life satisfaction-between schoolchildren with and without a chronically ill or disabled parent at home. It also examines the role played by the intensity of tasks, life circumstances, and social support at home and school. In 2017, a Dutch representative sample of adolescents aged between 12 and 16 (from the Health Behaviour in School-aged Children study) completed a questionnaire about illness of family members, tasks at home, life circumstances and characteristics, social support, psychosomatic complaints and life satisfaction. In total, 5470 schoolchildren who did not have a parent with a chronic illness and 652 who did have a parent with a chronic illness were selected (average age 13.9). Stepwise multilevel logistic regression analyses in STATA were used. Schoolchildren with an ill parent had more psychosomatic complaints and lower life satisfaction than their counterparts without an ill parent, even when controlling for extra task hours, specific life circumstances and characteristics (e.g., more likely to be growing up in a single-parent family or stepfamily and more likely to be female), and lower perceived support. These aspects are also predictors of a lower quality of life. Professionals should address these aspects of the life of schoolchildren with a sick parent in such a way that they are facilitated to make a successful transition to adulthood.

Psychosocial functioning in adolescents growing up with chronic disease: The Dutch HBSC study.

Many adolescents worldwide (indirectly) grow up with a chronic disease, which may impact their functioning and wellbeing. The objective of this study is to assess whether adolescents with a (family member with a) chronic disease differ from their healthy counterparts in terms of psychosocial functioning. Data from the Dutch 2013 HBSC-survey were used, including 7168 adolescents (Meanage = 13.7, SD = 1.57, 50.5% female). Participants indicated whether they or one of their family members had a long-term (> 3 months) disease or disability (mental/physical) and were categorized into four groups based on disease presence (none, other, self, both). Psychosocial functioning was assessed in terms of life satisfaction, self-rated health, psychosomatic health, mental health problems, support, substance use, physical exercise, screen time, and school liking. Chronically diseased adolescents (n = 162) reported lower life satisfaction, self-rated and psychosomatic health, more mental health problems, lower peer support, more substance use, and less physical exercise compared to healthy peers. Chronically diseased adolescents who also had a family member with a chronic disease (n = 74) showed comparable outcomes on these life domains, although they did not differ from their healthy peers regarding peer support, substance use, and physical activity. Healthy adolescents with a chronically diseased family member (n = 737) reported significantly lower life satisfaction, self-rated and psychosomatic health, more mental health problems, and less family support compared to healthy peers who grew up in healthy families; however, they reported more positive outcomes than adolescents who had a chronic disease themselves.Conclusion: Having a (family member with a) chronic disease is associated with impaired psychosocial functioning on various life domains. Our findings aid in understanding the psychosocial associates of chronic disease and imply that caregivers should be observant of psychosocial problems among vulnerable adolescents to provide appropriate guidance. What is Known: • Adolescents who grow up with a (family member with a) chronic disease encounter numerous challenges that may be related to poorer developmental outcomes on the long term. What is New: • This study adds a comprehensive overview of the psychosocial functioning of adolescents with a (family member with a) chronic disease, as compared to healthy counterparts that grow up in a healthy family.

Correction: Dependency on the TYK2/STAT1/MCL1 axis in anaplastic large cell lymphoma.

An amendment to this paper has been published and can be accessed via a link at the top of the paper.

Dependency on the TYK2/STAT1/MCL1 axis in anaplastic large cell lymphoma.

TYK2 is a member of the JAK family of tyrosine kinases that is involved in chromosomal translocation-induced fusion proteins found in anaplastic large cell lymphomas (ALCL) that lack rearrangements activating the anaplastic lymphoma kinase (ALK). Here we demonstrate that TYK2 is highly expressed in all cases of human ALCL, and that in a mouse model of NPM-ALK-induced lymphoma, genetic disruption of Tyk2 delays the onset of tumors and prolongs survival of the mice. Lymphomas in this model lacking Tyk2 have reduced STAT1 and STAT3 phosphorylation and reduced expression of Mcl1, a pro-survival member of the BCL2 family. These findings in mice are mirrored in human ALCL cell lines, in which TYK2 is activated by autocrine production of IL-10 and IL-22 and by interaction with specific receptors expressed by the cells. Activated TYK2 leads to STAT1 and STAT3 phosphorylation, activated expression of MCL1 and aberrant ALCL cell survival. Moreover, TYK2 inhibitors are able to induce apoptosis in ALCL cells, regardless of the presence or absence of an ALK-fusion. Thus, TYK2 is a dependency that is required for ALCL cell survival through activation of MCL1 expression. TYK2 represents an attractive drug target due to its essential enzymatic domain, and TYK2-specific inhibitors show promise as novel targeted inhibitors for ALCL.

Synergistic cross-talk of hedgehog and interleukin-6 signaling drives growth of basal cell carcinoma.

Persistent activation of hedgehog (HH)/GLI signaling accounts for the development of basal cell carcinoma (BCC), a very frequent nonmelanoma skin cancer with rising incidence. Targeting HH/GLI signaling by approved pathway inhibitors can provide significant therapeutic benefit to BCC patients. However, limited response rates, development of drug resistance, and severe side effects of HH pathway inhibitors call for improved treatment strategies such as rational combination therapies simultaneously inhibiting HH/GLI and cooperative signals promoting the oncogenic activity of HH/GLI. In this study, we identified the interleukin-6 (IL6) pathway as a novel synergistic signal promoting oncogenic HH/GLI via STAT3 activation. Mechanistically, we provide evidence that signal integration of IL6 and HH/GLI occurs at the level of cis-regulatory sequences by co-binding of GLI and STAT3 to common HH-IL6 target gene promoters. Genetic inactivation of Il6 signaling in a mouse model of BCC significantly reduced in vivo tumor growth by interfering with HH/GLI-driven BCC proliferation. Our genetic and pharmacologic data suggest that combinatorial HH-IL6 pathway blockade is a promising approach to efficiently arrest cancer growth in BCC patients.

Socio-demographic Correlates of Fathers' and Mothers' Parenting Behaviors.

In the present study, we investigated whether fathers' and mothers' parenting behavior is differentially related to parental factors (such as age and employment), child factors (age and gender) as well as social support. Parents reported on their use of a broad range of parenting behaviors, including affection, responsivity, explaining, autonomy, support, rewarding, and punishing. We used survey data from the Netherlands for 1197 mothers and 903 fathers of children aged 2 to 17. Seemingly unrelated regression analyses were conducted to combine the regression results on the separate subsamples (fathers and mothers) and to test for differences in the coefficients between those subsamples. Our expectation that the parenting behavior of fathers is more dependent on parents' characteristics, children's characteristics, and social support than that of mothers was only partly confirmed by the results of our analysis. In general, our results suggest that fathers' parenting behaviors seem to be associated with parental and child characteristics and contextual factors in ways that are similar to how these factors are associated with mothers' parenting behaviors. Results are discussed in relation to the roles and expectations associated with motherhood and fatherhood.

O cinema no debate sobre o envelhecer / The cinema in the debate about aging / El cine en el debate sobre el envejecimiento

O envelhecimento populacional é um fenômeno mundial. Como uma estratégia de discutir o envelhecimento, originou-se o Projeto: Ciclo de Cinema "Envelhecimento", que desde 2009, busca através de filmes aproximar as questões da velhice da população de Santa Maria, RS. Neste artigo destacou-se o filme "Um Senhor Estagiário: Experiência nunca é demais" que, em sua exibição durante o Projeto, possibilitou um amplo debate acerca do processo de envelhecimento, fundado em teóricos da área da gerontologia.

Population aging is a worldwide phenomenon. As a strategy to discuss aging, the Project: Cinema Cycle "Aging", which since 2009, seeks through films to approach issues of old age in the population of Santa Maria, RS. In this article we highlight the film "A Master Trainee: Experience is never too much" that in its exhibition during the Project made possible a wide debate about the aging process, based on gerontology theorists.

Microenvironment-induced CD44v6 promotes early disease progression in chronic lymphocytic leukemia.

Chronic lymphocytic leukemia (CLL) outgrowth depends on signals from the microenvironment. We have previously found that in vitro reconstitution of this microenvironment induces specific variant isoforms of the adhesion molecule CD44, which confer human CLL with high affinity to hyaluronan (HA). Here, we determined the in vivo contribution of standard CD44 and its variants to leukemic B-cell homing and proliferation in Tcl1 transgenic mice with a B-cell-specific CD44 deficiency. In these mice, leukemia onset was delayed and leukemic infiltration of spleen, liver, and lungs, but not of bone marrow, was decreased. Competitive transplantation revealed that CLL homing to spleen and bone marrow required functional CD44. Notably, enrichment of CD44v6 variants particularly in spleen enhanced CLL engraftment and proliferation, along with increased HA binding. We recapitulated CD44v6 induction in the human disease and revealed the involvement of MAPK and NF-κB signaling upon CD40 ligand and B-cell receptor stimulation by in vitro inhibition experiments and chromatin immunoprecipitation assays. The investigation of downstream signaling after CD44v6-HA engagement uncovered the activation of extracellular signal-regulated kinase and p65. Consequently, anti-CD44v6 treatment reduced leukemic cell proliferation in vitro in human and mouse, confirming the general nature of the findings. In summary, we propose a CD44-NF-κB-CD44v6 circuit in CLL, allowing tumor cells to gain HA binding capacity and supporting their proliferation.

Salmonella enterica subsp. diarizonae serotype 61:k:1,5,(7) associated with chronic proliferative rhinitis and high nasal colonization rates in a flock of Texel sheep in Switzerland.

Salmonella (S.) enterica subspecies diarizonae (IIIb) serovar 61:(k):1,5,(7) (S. IIIb 61:(k):1,5,(7)) is considered to be host adapted to sheep and is found regularly in feces of healthy carriers and of sheep with salmonellosis. A few cases of chronic proliferative rhinitis (CPR) in sheep have been described as a new disease in association with S. IIIb 61:k:1,5,(7) in the USA, in Spain and now for the first time in Switzerland. Three animals of a flock of Texel sheep suffering from chronic nasal discharge and dyspnea with subsequent death were necropsied. The pathological lesions are consistent with a severe proliferation of the nasal mucosae of the turbinates in association with severe chronic inflammation. S. IIIb 61:(k):1,5,(7) was isolated from the lesions by direct bacteriological culture and the presence of Salmonella spp. was confirmed by immunohistochemistry. The affected flock was systematically tested after the first occurrence of the disease. Clinical examination of the flock revealed approx. 20% of the adult sheep to show nasal discharge, approx. 5% having severe dyspnea and approx. 5% having chronic intermittent diarrhea. Lambs (n=28) showed no clinical signs at all. High positivity of nasal mucosa (46%), but low prevalence in feces (6%) for S. IIIb 61:k:1,5,(7) was found. The results lead to the assumption of a direct animal to animal transmission by nasal discharge followed by a chronic disease leading to death after several months to years. Animals tested positive for S. IIIb 61:k:1,5,(7) were all >1year old. CPR represents a chronic disease in adult sheep posing a risk for spreading S. IIIb 61:k:1,5,(7) between flocks and with a zoonotic potential.

CCL2 is a KIT D816V-dependent modulator of the bone marrow microenvironment in systemic mastocytosis.

Systemic mastocytosis (SM) is characterized by abnormal accumulation of neoplastic mast cells harboring the activating KIT mutation D816V in the bone marrow and other internal organs. As found in other myeloproliferative neoplasms, increased production of profibrogenic and angiogenic cytokines and related alterations of the bone marrow microenvironment are commonly found in SM. However, little is known about mechanisms and effector molecules triggering fibrosis and angiogenesis in SM. Here we show that KIT D816V promotes expression of the proangiogenic cytokine CCL2 in neoplastic mast cells. Correspondingly, the KIT-targeting drug midostaurin and RNA interference-mediated knockdown of KIT reduced expression of CCL2. We also found that nuclear factor κB contributes to KIT-dependent upregulation of CCL2 in mast cells. In addition, CCL2 secreted by KIT D816V+ mast cells was found to promote the migration of human endothelial cells in vitro. Furthermore, knockdown of CCL2 in neoplastic mast cells resulted in reduced microvessel density and reduced tumor growth in vivo compared with CCL2-expressing cells. Finally, we measured CCL2 serum concentrations in patients with SM and found that CCL2 levels were significantly increased in mastocytosis patients compared with controls. CCL2 serum levels were higher in patients with advanced SM and were found to correlate with poor survival. In summary, we have identified CCL2 as a novel KIT D816V-dependent key regulator of vascular cell migration and angiogenesis in SM. CCL2 expression correlates with disease severity and prognosis. Whether CCL2 may serve as a therapeutic target in advanced SM remains to be determined in forthcoming studies.

Growing Up With the Right to Marry: Sexual Attraction, Substance Use, and Well-Being of Dutch Adolescents.

PURPOSE: To assess the well-being and substance use of sexual minority adolescents growing up in a tolerant society, we examined differences among same-sex attracted (SSA), those who do not know their attraction yet (not yet attracted [NYA]), and heterosexual Dutch adolescents. METHODS: Unadjusted and adjusted logistic and linear multilevel analyses were performed using representative data of the 2013 Health Behaviour in School-Aged Children study (N = 5,995; 11-16 years old). The adjusted analyses controlled for sociodemographics (gender, age, education type, ethnicity, urbanicity, and religion). RESULTS: Adjusted results showed that SSA adolescents substantially more often reported alcohol use (adjusted odds ratio [AOR] = 2.01), tobacco smoking (AOR = 2.37), and cannabis smoking (AOR = 3.52) than their heterosexual peers, while NYA participants less often reported alcohol use (AOR = .57) and equal levels of tobacco (AOR = .71) and cannabis smoking (AOR = .87) compared with heterosexual adolescents. SSA adolescents reported lower levels of life satisfaction (b = -1.25) and higher levels of psychosomatic complaints (b = .61) and emotional problems (b = 1.57) than heterosexual adolescents. NYA adolescents reported equal levels of life satisfaction (b = -.18) and psychosomatic complaints (b = .06) as heterosexual adolescents, but higher levels of emotional problems (b = .51). CONCLUSIONS: In Dutch society, with over 20 years of inclusive policies for sexual minorities and generally tolerant population attitudes toward sexual minorities, SSA adolescents are still at increased risk of substance use and have lower levels of well-being compared with peers.

Binding studies on isolated porcine small intestinal mucosa and in vitro toxicity studies reveal lack of effect of C. perfringens beta-toxin on the porcine intestinal epithelium.

Beta-toxin (CPB) is the essential virulence factor of C. perfringens type C causing necrotizing enteritis (NE) in different hosts. Using a pig infection model, we showed that CPB targets small intestinal endothelial cells. Its effect on the porcine intestinal epithelium, however, could not be adequately investigated by this approach. Using porcine neonatal jejunal explants and cryosections, we performed in situ binding studies with CPB. We confirmed binding of CPB to endothelial but could not detect binding to epithelial cells. In contrast, the intact epithelial layer inhibited CPB penetration into deeper intestinal layers. CPB failed to induce cytopathic effects in cultured polarized porcine intestinal epithelial cells (IPEC-J2) and primary jejunal epithelial cells. C. perfringens type C culture supernatants were toxic for cell cultures. This, however, was not inhibited by CPB neutralization. Our results show that, in the porcine small intestine, CPB primarily targets endothelial cells and does not bind to epithelial cells. An intact intestinal epithelial layer prevents CPB diffusion into underlying tissue and CPB alone does not cause direct damage to intestinal epithelial cells. Additional factors might be involved in the early epithelial damage which is needed for CPB diffusion towards its endothelial targets in the small intestine.

Trends in adolescents' perceived parental communication across 32 countries in Europe and North America from 2002 to 2010.

BACKGROUND: The quality of communication with parents is a determinant of health and well-being during adolescence, being predictive of self-esteem, self-rated health and the ability to navigate health risk behaviours. METHODS: This article describes trends in adolescent's (aged 11, 13 and 15 years) perception of communication with mothers and fathers by gender across 32 European and North American countries from 2002 to 2010. Analyses were performed on 425 699 records employing a General Linear Model (MANOVA). RESULTS: In most countries, significant increases in the prevalence of ease of communication with both mothers and fathers were observed, with the greatest positive changes over time in Estonia, Denmark and Wales. In some countries, the opposite trend was found with the greatest negative changes occurring in France, Slovenia and Poland. Across the pooled dataset, a significant positive trend was observed for ease of communication with father, for both boys and girls and for ease of communication with mother for boys only. CONCLUSION: The temporal trends demonstrated an increase in a positive health asset for many young people, that of family communication. Positive trends may be a feature of the economic boom over the past decade coupled with cultural changes in attitudes to parenting, especially fathering.

Mycobacterium avium Subsp. avium infection in four veal calves: differentiation from intestinal tuberculosis.

Mycobacterium avium subsp. avium (Maa) is an intracellular pathogen belonging to the Mycobacterium avium-intracellulare complex (MAC). Reservoirs of MAC are the natural environment, wildlife and domestic animals. In adult bovine, MAC infections are typically caused by Mycobacterium avium subsp. paratuberculosis (Map). Maa infections in bovine are rarely reported but may cause clinical disease and pathological lesions similar to those observed in paratuberculosis or those induced by members of the Mycobacterium tuberculosis complex (MTBC). Therefore, differentiation of MAC from MTBC infection should be attempted, especially if unusual mycobacterial lesions are encountered. Four veal calves from a fattening farm dying with clinical signs of otitis media, fever, and weight loss were submitted for necropsy. Samples from affected organs were taken for histologic investigation, bacteriologic culture, and bacterial specification using PCR. Macroscopic thickening of the intestinal mucosa was induced by granulomatous enteritis and colitis. Intracytoplasmic acid-fast bacteria were detected by Ziehl-Neelsen stains and PCR revealed positive results for Mycobacterium avium subsp. avium. Clinical and pathological changes of Maa infection in veal calves had features of Mycobacterium avium subsp. paratuberculosis and the MTBC. Therefore, Mycobacterium tuberculosis complex infection should be considered in cases of granulomatous enteritis in calves.
