Emotional management and biological markers of dietetic regimen in chronic kidney disease patients

The aim of the study was to investigate the association between psychological characteristics and biological markers of adherence in chronic kidney disease patients receiving conservative therapy, hemodialysis, peritoneal dialysis (PD), or kidney transplantation. Seventy-nine adult patients were asked to complete the following questionnaires: Toronto Alexithymia scale, Snaith–Hamilton Pleasure Scale, and Short Form Health Survey. Biological markers of adherence to treatment were measured. Peritoneal dialysis patients showed a lower capacity to feel pleasure from sensorial experience (p = .011) and a higher values of phosphorus compared to the other patients’ groups (p = .0001). The inability to communicate emotions was negatively correlated with hemoglobin levels (r = −(0).69; p = .001) and positively correlated with phosphorus values in the PD patients (r = .45; p = .050). Findings showed higher psychological impairments and a lower adherence to the treatment in PD patients and suggest the implication of emotional competence in adherence to treatment.The aim of the study was to investigate the association between psychological characteristics and biological markers of adherence in chronic kidney disease patients receiving conservative therapy, hemodialysis, peritoneal dialysis (PD), or kidney transplantation.

The attachment and its role in medical care

Attachment styles are relational models that lead an individual to seek proximity to a safe or powerful person when threatened. As suggested by attachment theory, the quality of early interpersonal experiences shapes the self-regulate ability during the entire life span and modulate the complex relationship between social, cognitive, and emotional variables. The attachment system seems to be strongly involved in the health-related events, due to its self-regulation function. Individuals with physical illness are forced to cope with new people, contexts and experiences that are potential stressors of attachment system. Relational models, thus, seem to have a significant role in health-related psychological processes, in particular, on patients' ability to engage in a fruitful alliance with their physicians. Major chronic conditions and their complex management could broadly take advantage from a safely and trustful relationship between patient and physician. Patient medical adherence is a basic statement in health care and recent studies reported that it is closely associated with the affective relationship between patient and practitioner. Investigating the patient attachment style as a moderator of this relationship could promote clinical interventions aimed to enhance the adherence to medical care, improving health-care outcomes and patient quality of life

Effectiveness of Expressive Writing in Kidney Transplanted Patients: A Randomized Controlled Trial Study

The present study aimed to assess the effectiveness of an expressive writing (EW) intervention on psychological and physiological variables after kidney transplant. The final sample of 26 were randomly assigned to an expressive writing group (EWG) and control group (CG). Outcomes were focused on depression, anxiety, alexithymia, empathy, resilience, locus of control, creatinine, CDK-EPI, and azotemia. Depressive symptoms and alexithymia levels decreased in the EWG, with better adherence. Resilience declined over time in both groups. The EWG showed a significantly higher CDK-EPI, indicating better renal functioning. EW seems an effective intervention to improve the psychological health of transplanted patients, with a possible effect on renal functioning. These findings open the possibility of planning brief psychological interventions aimed at processing emotional involvement, in order to increase adherence, the acceptance of the organ, and savings in healthcare costs

Externally oriented thinking predicts phosphorus levels in dialyzed patients

Background. The aim of the present study was to investigate the association between alexithymia scores and biological markers of adherence in dialyzed patients. The hypothesis was that higher scores of alexithymia would be associated with lower adherence to treatment. Methods. Fifty-four adult dialyzed patients were enrolled during a follow-up visit. Participants were asked to complete a self-report questionnaire, namely, the Toronto Alexithymia Scale (TAS-20). Moreover, biological markers levels of adherence to treatment (phosphorus, creatinine, and serum uric acid) were measured. Results. A positive correlation was found between phosphorous levels and TAS-F2 (r = 0.28; P = .04) and TAS-F3 (r = -0.31; P = .02). Stepwise regression with TAS-F2 and TAS-F3 as predictors of adherence to treatment showed a significant model, adjusted R-2 = 0.08, F(1,52) = 5.4; P < .02, where only TAS-F3 was able to predict phosphorous levels (P =.02)

GM1 Oligosaccharide Crosses the Human Blood–Brain Barrier In Vitro by a Paracellular Route

International audienceGanglioside GM1 (GM1) has been reported to functionally recover degenerated nervous system in vitro and in vivo, but the possibility to translate GM1's potential in clinical settings is counteracted by its low ability to overcome the blood-brain barrier (BBB) due to its amphiphilic nature. Interestingly, the soluble and hydrophilic GM1-oligosaccharide (OligoGM1) is able to punctually replace GM1 neurotrophic functions alone, both in vitro and in vivo. In order to take advantage of OligoGM1 properties, which overcome GM1's pharmacological limitations, here we characterize the OligoGM1 brain transport by using a human in vitro BBB model. OligoGM1 showed a 20-fold higher crossing rate than GM1 and time-concentration-dependent transport. Additionally, OligoGM1 crossed the barrier at 4 °C and in inverse transport experiments, allowing consideration of the passive paracellular route. This was confirmed by the exclusion of a direct interaction with the active ATP-binding cassette (ABC) transporters using the "pump out" system. Finally, after barrier crossing, OligoGM1 remained intact and able to induce Neuro2a cell neuritogenesis by activating the TrkA pathway. Importantly, these in vitro data demonstrated that OligoGM1, lacking the hydrophobic ceramide, can advantageously cross the BBB in comparison with GM1, while maintaining its neuroproperties. This study has improved the knowledge about OligoGM1's pharmacological potential, offering a tangible therapeutic strategy
