Couples dealing with pediatric blood cancer : a study on the role of dyadic coping

Objective: Pediatric cancer is a life-threatening disease that poses significant challenges to the ill child and his/her parents. Among the studies investigating risk and protective factors for the individual and relationship adjustment of parents being confronted with pediatric cancer, couple factors - such as dyadic coping - gained little research attention. Therefore, the aim of the current study was to explore the association between dyadic coping and individual/relationship outcomes of parents in the context of pediatric cancer. Methods: Participants were 59 couples of children diagnosed with leukemia or Non-Hodgkin lymphoma. Time since diagnosis varied from diagnosis to 20 months. Both parents completed the DCI-short, DASS21, PIP, and MMQ. Results: Positive dyadic coping (i.e., supportive and common dyadic coping) and negative dyadic coping proved to be related to individual and relational outcomes of parents facing cancer in their child. In addition, while men and women reported to be equally satisfied with their partner and their sexual relationship, women reported higher levels of individual maladjustment. Conclusion: Our findings led to the conclusion that dyadic coping is important for both individual as well as relationship outcomes of parents when facing a diagnosis of cancer in their child. When meeting with families, both partners should be invited as a unit in order to best capture couple level experiences. Also, clinicians should be sensitive to relational and sexual issues besides individual issues, taking into account evidence-based standards for psychosocial care in pediatric oncology

Numb “Adapting” Notch for Endocytosis

AbstractDuring sensory organ precursor divisions in Drosophila, the numb gene product segregates asymmetrically into one of the two daughter cells, to which it confers a specific fate by inhibiting Notch signaling. In this issue of Developmental Cell, Berdnik et al. show that Numb recruits α-Adaptin and that this physical interaction plays a role in downregulating Notch, presumably by stimulating endocytosis of Notch

Aberrant lysosomal carbohydrate storage accompanies endocytic defects and neurodegeneration in Drosophila benchwarmer

Lysosomal storage is the most common cause of neurodegenerative brain disease in preadulthood. However, the underlying cellular mechanisms that lead to neuronal dysfunction are unknown. Here, we report that loss of Drosophila benchwarmer (bnch), a predicted lysosomal sugar carrier, leads to carbohydrate storage in yolk spheres during oogenesis and results in widespread accumulation of enlarged lysosomal and late endosomal inclusions. At the bnch larval neuromuscular junction, we observe similar inclusions and find defects in synaptic vesicle recycling at the level of endocytosis. In addition, loss of bnch slows endosome-to-lysosome trafficking in larval garland cells. In adult bnch flies, we observe age-dependent synaptic dysfunction and neuronal degeneration. Finally, we find that loss of bnch strongly enhances tau neurotoxicity in a dose-dependent manner. We hypothesize that, in bnch, defective lysosomal carbohydrate efflux leads to endocytic defects with functional consequences in synaptic strength, neuronal viability, and tau neurotoxicity

Family members dealing with childhood cancer : a study on the role of family functioning and cancer appraisal

Objectives: Childhood cancer is a life-threatening disease that poses significant challenges to the life of the diagnosed child and his/her family members. Based on the ABCX-model, the aim of the current study was to explore the association between family functioning, cancer appraisal and the individual adjustment of patients, parents and siblings. Methods: Participants were 60 children with leukemia or non-Hodgkin lymphoma, 172 parents and 78 siblings (115 families). Time since diagnosis varied from zero to 33 months. Patients, parents and siblings completed the Family Environment Scale (FES), Perceived Stress Scale, Situation-Specific Emotional Reactions Questionnaire and Pediatric Quality of Life Inventory/Maudsley Marital Questionnaire. Results: Family functioning and the appraisal of the cancer diagnosis proved to be related to patients', parents' and siblings' cancer-related emotions and quality of life post-diagnosis. In addition, family members differed in their perception of some family functioning domains, the appraisal of the cancer diagnosis, positive feelings and quality of life. Discussion: Our findings led to the conclusion that family functioning and the appraisal of the cancer diagnosis are important for the individual adjustment of patients, parents and siblings when facing a diagnosis of cancer in the child. Differences across members within one family and differences between families speak to the need of screening all family members and intervening at the level of individual as well as the family unit

Family adjustment when facing pediatric cancer : the role of parental psychological flexibility, dyadic coping, and network support

Objectives Pediatric cancer is a life-threatening disease that poses significant challenges to the life of all family members (diagnosed child, parents, and siblings) and the family as a whole. To date, limited research has investigated family adjustment when facing pediatric cancer. The aim of the current study was to explore the role of protective factors at the individual (parental psychological flexibility), intrafamilial (dyadic coping) and contextual level (network support) in explaining family adjustment as perceived by parents of children with leukemia or non-Hodgkin lymphoma. In addition, we were interested to see whether these protective factors could be predictive for family adjustment at a later time point. Method Participants were 70 mothers and 53 fathers (80 families) of children with leukemia or non-Hodgkin lymphoma. Mean time since diagnosis was 5.26 (T1) and 18.86 (T2) months post-diagnosis. Parents completed the Acceptance and Action Questionnaire II (to assess psychological flexibility), Dyadic Coping Inventory, a network support questionnaire, Impact on Family Scale and the Family Adjustment Scale. Both concurrent and prospective association models were tested. Results Psychological flexibility, dyadic coping and network support proved to be cross-sectionally and positively related to parents' perception of family adjustment post-diagnosis; psychological flexibility and dyadic coping proved to predict better family adjustment over time. Conclusion Our findings led to the conclusion that protective factors at all three levels (individual, intrafamilial and contextual) are important for explaining family adjustment as perceived by parents facing a diagnosis of cancer in their child. Interventions targeting the individual, couple, as well as family level are warranted to enhance family adjustment

An appetite for destruction From self-eating to cell cannibalism as a neuronal survival strategy

Autophagy plays an important role in cellular survival by resupplying cells with nutrients during starvation or by clearing misfolded proteins and damaged organelles and thereby preventing degenerative diseases. Conversely, the autophagic process is also recognized as a cellular death mechanism. The circumstances that determine whether autophagy has a beneficial or a detrimental role in cellular survival are currently unclear. We recently showed that autophagy induction is detrimental in neurons that lack a functional AMPK enzyme (AMP-activated protein kinase) and that suffer from severe metabolic stress. We further demonstrated that autophagy and AMPK are interconnected in a negative feedback loop that prevents excessive and destructive stimulation of the autophagic process. Finally, we uncovered a new survival mechanism in AMPK-deficient neurons—cell cannibalism

Exploring residents and supervisors' workplace learning needs during postgraduate medical education

Abstract: Objectives: To identify the main enablers and challenges for workplace learning during postgraduate medical education among residents and their supervisors involved in training hospital specialists across different medical specialties and clinical teaching departments. Methods: A qualitative explorative study using semi-structured focus group interviews was employed. A purposeful sampling method was utilized to invite participants who were involved in postgraduate medical education for hospital specialist medicine at two universities. Hospital physicians in training, also called residents (n=876) and supervisors (n=66), were invited by email to participate. Three focus groups were organized: two with residents and one with supervisors. Due to the COVID-19 pandemic rules prohibiting real group meetings, these focus groups were online and asynchronous. The data was analyzed following an inductive thematic analysis. Results: The following overarching themes were identified: 1) the dual learning path, which balances working in the hospital and formal courses, 2) feedback, where quality, quantity, and frequency are discussed, and 3) learning support, including residents' self-directed learning, supervisors' guidance, and ePortfolio support. Conclusions: Different enablers and challenges for postgraduate medical education were identified. These results can guide all stakeholders involved with workplace learning to develop a better understanding of how workplace learning can be optimized to improve the postgraduate medical education experience. Future studies could focus on confirming the results of this study in a broader, perhaps international setting and exploring strategies for aligning residencies to improve quality
