Obesity is increasingly prevalent among adolescents. Clinical and research data support the use of bariatric surgery (BS) as a treatment option for severely obese adolescents, with good results in terms of weight loss, improvement or resolution of comorbidities, and compliance to follow up. Nevertheless, concerns still remain, with significant disparities among countries and ethical concerns mainly raised by performing an irreversible and invasive procedure in adolescence, with potential life-long alterations. In this context, the purpose of this narrative review was to discuss the main current ethical challenges in performing BS in adolescence and to inform appropriate clinical management in the field. The core ethical principles of autonomy, beneficence, nonmaleficence, and justice were revised in terms of patient-centered healthcare through the lens of psychosocial implications. The review concludes with a discussion regarding the potential directives for future research for effective, patient-centered, and ethical management of obesity in the adolescent population.

In this paper, we present the case of a 48-year-old woman diagnosed with early breast cancer. As candidate for mastectomy, she refused immediate reconstruction. She was referred to a psycho-oncologist for further evaluation and support. Psychological sessions helped reveal a history of intimate partner violence and helped clarify the reason for her refusal to undergo immediate reconstruction. Experience with this case highlights the importance of a multidisciplinary practice in which collaboration between surgeons, oncologists, and mental health professionals leads to a more in-depth understanding of the apparently paradoxical behaviors of patients, and to better care for their needs.

Videogames use has constantly increased among children and adolescents, with uncertain consequences on their health. This study aimed to assess the prevalence of videogames use and addiction in a sample of Italian children during the COVID-19 pandemic and their association with anxiety symptoms. One hundred and sixty-two children (M/F:78/84, age range: 8–10 years, average age 9.4 ± 0.7 years) completed the Videogame Addiction Scale for Children (VASC), the Test of Anxiety and Depression (TAD) and the Children’s Anxiety Meter—State (CAM-S). Demographic variables and data on the access to electronic tools and games preferences were also collected. Overall, 96.3% of the study participants stated to have access to one or more device. They reported a low risk of videogame addiction (VASC score (mean ± SD): 46.7 ± 15.4), a moderate level of trait anxiety (TAD score (mean ± SD): 135 ± 16.8) and a low state anxiety (CAM-S score (mean ± SD): 2.2 ± 2.1). Males reported to spend more time on videogames, to perceive higher self-control and to be more influenced by reinforcement mechanisms, females described higher levels of trait anxiety. In the regression analysis, state anxiety was a predictor of videogame use and addiction (p = 0.01). Further research is needed to confirm these data and to maximize the developmentally positive effects of videogames and preventing the negative consequences.

Heart failure is a disease of epidemic proportion, and is a leading cause of mortality in the world. Since cardiac myocytes are terminally differentiated cells with minimal intrinsic ability to self-regenerate, cardiac tissue engineering has emerged as one of the most realistic therapeutic strategies for cardiac repair. We have previously proven the ability of carbon nanotube scaffolds to promote cardiomyocytes proliferation, maturation and long-term survival. Here, we tested if 3-dimensional scaffolds of carbon nanotube-based composites can also promote cardiomyocyte growth, electrophysiological maturation, and formation of functional syncytia. To this purpose, we developed an elastomeric scaffold which consists of a microporous and self–standing material made of polydimethylsiloxane (PDMS) containing micrometric cavities, and integrated multi-wall carbon nanotubes (MWCNTs) into the scaffold. We combined microscopy, cell biology and calcium imaging, to investigate whether neonatal rat ventricular myocytes (NRVMs) cultured on the 3D-PDMS+MWCNT acquire a more viable and mature phenotype compared to control. We found that, when cultured in the 3D-PDMS+MWCNTs, NRVMs showed improved viability (p < 0.005 at day3) and more defined and mature sarcomeric phenotype compared to 3D PDMS control. These modifications were associated with an increase of connexin-43 gene expression, gap junction areas (p < 0.005 at day 3), and a more mature electrophysiological phenotype of syncytia and calcium transients. Finally, 3D-PDMS+MWCNT boosted NRVMs proliferation (p < 0.005 at day 3) while hindering cardiac fibroblasts proliferation compared to control PDMS. Thus, 3D-PDMS+MWCNT has the ability to promote viability, proliferation and functional maturation of cardiac myocytes. These properties are essential in cardiac tissue engineering and offer novel perspectives in the development of innovative therapies for cardiac repair.

Prader-Willi syndrome (PWS) is a complex genetic disorder and represents the most common genetic cause of life-threatening obesity in childhood and adolescence. The indication for bariatric surgery in children and adolescents with syndromic obesity is still controversial. This case report deals with the preoperative medical and psychosocial evaluation of a 16-y-old male adolescent with PWS who underwent sleeve gastrectomy. Information on a 6-mo follow-up is also reported. The preoperative body weight was 223 kg (body mass index [BMI] 80.9 kg/m2). Comorbidities included severe obstructive sleep apnea with nocturnal respiratory failure, hypertension, and impaired glucose tolerance. At 2- and 6-mo follow-ups, the percent excess weight loss was 16 (BMI 71.8 kg/m2) and 29.2 (BMI 64.6 kg/m2), respectively. Comorbities did improve. Intellectual disability of genetic origin per se may not represent an absolute contraindication to bariatric surgery if adequate and tailored clinical and psychosocial support is provided.

Rationale: Recent evidence indicates that a few human microRNAs (miRNAs), in particular hsa-miR-199a-3p and hsa-miR-590-3p, stimulate proliferation of cardiomyocytes and, once expressed in the mouse heart using viral vectors, induce cardiac regeneration after myocardial infarction. Viral vectors, however, are not devoid of safety issues and, more notably, drive expression of the encoded miRNAs for indefinite periods of time, which might not be desirable in light of human therapeutic application. Objective: As an alternative to the use of viral vectors, we wanted to assess the efficacy of synthetic miRNA mimics in inducing myocardial repair after single intracardiac injection using synthetic lipid formulations. Methods and Results: We comparatively analyzed the efficacy of different lipid formulations in delivering hsa-miR-199a-3p and hsa-miR-590-3p both in primary neonatal mouse cardiomyocytes and in vivo. We established a transfection protocol allowing persistence of these 2 mimics for at least 12 days after a single intracardiac injection, with minimal dispersion to other organs and long-term preservation of miRNA functional activity, as assessed by monitoring the expression of 2 mRNA targets. Administration of this synthetic formulation immediately after myocardial infarction in mice resulted in marked reduction of infarct size and persistent recovery of cardiac function. Conclusions: A single administration of synthetic miRNA–lipid formulations is sufficient to stimulate cardiac repair and restoration of cardiac function.

Defenses mechanisms are defined as the tools an individual uses to manage instincts, drives, and affects. Transplantation is a stressful event that requires the body to mobilize its internal and external defenses and implement coping and adaptation strategies, which can be essential for overcoming the painful and potentially dangerous environmental, existential, and relational situations that may occur after transplantation. The aim of our study was to analyze the defense styles in 50 kidney transplanted subjects and to correlate the latter with any psychopathology and the quality of life subjectively perceived. The Defense Style Questionnaire was administered to evaluate the defense mechanisms. The Symptom Checklist-90-R (SCL-90-R) was used for the evaluation of any psychopathology. Quality of life was studied using the Complete Form Health Survey (SF-36). The "somatization" (SOM) and "anxiety" (ANX) dimensions of the SCL-90 R correlated significantly with the "reaction formation" (RF) neurotic defense (RF/SOM r = .893; RF/ANX r = .966; P .05). A good perception of one's "general health" (GH) correlated significantly with the "humor" (HU) and "sublimation" (SU) mature defenses (HU/GH r = .681; SU/GH r = .524; P .05). Kidney transplanted subjects are exposed to persistent physical and psychosocial stress and each transplanted subject uses their own defense mechanisms to contain the mental pain and reduce the emotional stress derived from the transplantation experience. Identifying the different kinds of defenses (mature, immature, or neurotic) can be an effective way to search for predictive indices of a good quality of life and adherence to treatments.

Personality Tests ,Living Donors ,Humans ,Personality - Abstract
The term Samaritan is used to indicate the choice of a living donor to offer its own organ to save the life of a patient with whom it has no parental or affective relation (article 1, Law of 26 June 1967). It is a gesture of great solidarity, one that promotes life. The purpose of this study has been to analyze a case of potential Samaritan donation. The investigation consisted of six interviews, on a bi-weekly basis, for a total duration of three months. The clinical interviews allowed us to delve deeper into the motivations for the donation. The following tests were administered: the Rorschach projective test, the Millon Clinical Multiaxial Inventory Personality Test (MCMI-III) and the Symptom Checklist-90-Revised (SCL-90-R). Some issues regarding age, self-confidence, emotional difficulties and maladjustment to social environment emerged. The analysis of the test results confirmed the "negative" indices that led the authors to decide against the psychological-psychiatric suitability for the Samaritan donation. The Samaritan donation is a rare and precious donation and understanding in depth the motivations behind this choice is extremely important. The choice to donate, even if freely made, must not make one forget their responsibility towards themselves and towards the integrity of their own body.

Transplant recipients have difficulty expressing, identifying, and describing their emotional experiences. The Machover human figure test allows us to bring out the deepest contents of a patient's personality, which are normally hidden and not explained to structured quantitative tests. The study analyzed possible situations of distress and possible symptoms of psychopathology in kidney transplant recipients, emerged from the projective test of the human figure and not easily verbalized to the common standardized tests. The sample included 80 kidney transplant patients (51 men and 29 women; mean age, 47.74 [SD, 12.39] years) during follow-up visits at 12 months after transplant. The Machover test was used to evaluate body image, affective aspects, and personality variables by projective method; the Symptom Checklist-90-R was used for the evaluation of possible psychopathology, and the 36-Item Short Form Health Survey was used for the assessment of perceived quality of life. RESULTS: showed that the more anxiety there is in the human figure test, the less somatization dimensions (ANX/SOM R = -331, P .05), depression (ANX/DEP R = -326, P .05), and the global index of psychic symptomatology (ANX/GSI R = -367, P .05) of the Symptom Checklist-90-R are present. This research has confirmed the hypothesis that the spontaneous graphic production of the recipients, through the projective methods, allows them to identify and deepen their psychological contents and to activate and maintain a good psychophysical balance post transplant.

Background In the context of kidney transplantation (KT), multidisciplinary interventions, including assessment and management of psychosocial aspects, are important to improve transplant's outcome. The aim of this study was to describe a multidisciplinary team approach to KT, with a specific focus on early detection and treatment of psychological distress and psychopathologic conditions in the early phase postsurgery. Methods The multidisciplinary team in kidney transplantation was implemented in January 2016. In this team approach, all transplant recipients are invited to 3 scheduled appointments for a multidisciplinary evaluation at 1, 3, and 6 months posttransplant, including a psychiatric interview, with the aim to assess the patient's adjustment after transplantation and provide support when necessary. Results This pilot study involved all 41 KT recipients consecutively referred for the first multidisciplinary appointment after transplantation. Five subjects (12% of the study sample) presented with a current psychiatric diagnosis. Psychopharmacologic treatment was confirmed or introduced for all these patients. Further psychological support was suggested to 4 other patients (10%). Conclusion KT significantly improves patients' quality of life. However, the percentage of subjects receiving psychopharmacologic treatment and referred for further psychological and psychiatric support (22%) suggests the need for careful monitoring of psychosocial aspects over the long term.

In a tissue continuously challenged by mechanical stresses, such as the skin or the heart, cells perceive information about their microenvironment through several adhesive protein complexes and activate cell-signaling events to maintain tissue cohesion. Consequently, alteration of cell adhesion components leads to aberrant assembly of the associated cytoplasmic scaffolding and signaling pathways, which may reflect changes to the tissue physiology and mechanical resistance. Desmoplakin is an essential component of the cell-cell junction, anchoring the desmosomal protein complex to the intermediate filaments (IFs). Inherited mutations in desmoplakin are associated with both heart and skin disease (cardiocutaneous syndrome). In this study, we investigated the mechanical properties of human keratinocytes harboring a cardiocutaneous-associated homozygous C-terminal truncation in desmoplakin (JD-1) compared to a control keratinocyte line (K1). Using Single Cell Force Spectroscopy (SCFS) AFM-based measurements, JD-1 keratinocytes displayed an overall alteration in morphology, elasticity, adhesion capabilities and viscoelastic properties, highlighting the profound interconnection between the adhesome pathways and the IF scaffold.

Aims Given the clinical impact of LMNA cardiomyopathies, understanding lamin function will fulfill a clinical need and will lead to advancement in the treatment of heart failure. A multidisciplinary approach combining cell biology, atomic force microscopy (AFM), and molecular modeling was used to analyse the biomechanical properties of human lamin A/C gene (LMNA) mutations (E161K, D192G, N195K) using an in vitro neonatal rat ventricular myocyte model. Methods and results The severity of biomechanical defects due to the three LMNA mutations correlated with the severity of the clinical phenotype. AFM and molecular modeling identified distinctive biomechanical and structural changes, with increasing severity from E161K to N195K and D192G, respectively. Additionally, the biomechanical defects were rescued with a p38 MAPK inhibitor. Conclusions AFM and molecular modeling were able to quantify distinct biomechanical and structural defects in LMNA mutations E161K, D192G, and N195K and correlate the defects with clinical phenotypic severity. Improvements in cellular biomechanical phenotype was demonstrated and may represent a mechanism of action for p38 MAPK inhibition therapy that is now being used in human clinical trials to treat laminopathies.

Lung transplantation (LT) increases the life expectancy of patients affected by end stage pulmonary disease; specifically, its ultimate aims are to improve survival and health related quality of life (HRQoL). The aim of the present longitudinal study was to determine the HRQoL trajectory and changes in functional capacity from time of entry in the waiting list for LT to 2 year after LT. The study included sixty-nine outpatients enrolled in a single medical center when they entered the waiting list for LT and who subsequently received it. They were then followed up over 2 years after LT. HRQoL was assessed by the physical and mental component summary (PCS and MCS) scores of the 36-item Short Form Health Survey (SF-36) and Saint George’s Respiratory Questionnaire (SGRQ). Psychological distress was evaluated with the General Health Questionnaire (GHQ), and functional capacity was investigated using the six-minute walk test (6MWT) and forced expiratory volume (FEV1). Patients showed low SF-36 PCS (30.5±7.8) and SGRQ total (61.8±17.5) scores at entry in the waiting list, but exhibited significant changes over time after LT (p

Background: Mutations in genes encoding intercalated disk/desmosome proteins, such as plakophilin 2 (PKP2), cause arrhythmogenic cardiomyopathy (ACM). Desmosomes are responsible for myocyte&ndash, myocyte attachment and maintaining mechanical integrity of the myocardium. Methods: We knocked down Pkp2 in HL-1 mouse atrial cardiomyocytes (HL-1Pkp2-shRNA) and characterized their biomechanical properties. Gene expression was analyzed by RNA-Sequencing, microarray, and qPCR. Immunofluorescence was used to detect changes in cytoskeleton and focal adhesion. Antagomirs were used to knock down expression of selected microRNA (miR) in the rescue experiments. Results: Knockdown of Pkp2 was associated with decreased cardiomyocyte stiffness and work of detachment, and increased plasticity index. Altered mechanical properties were associated with impaired actin cytoskeleton in HL-1Pkp2-shRNA cells. Analysis of differentially expressed genes identified focal adhesion and actin cytoskeleton amongst the most dysregulated pathways, and miR200 family (a, b, and 429) as the most upregulated miRs in HL-1Pkp2-shRNA cells. Knockdown of miR-200b but not miR-200a, miR-429, by sequence-specific shRNAs partially rescued integrin-&alpha, 1 (Itga1) levels, actin organization, cell adhesion (on collagen), and stiffness. Conclusions: PKP2 deficiency alters cardiomyocytes adhesion through a mechanism that involves upregulation of miR-200b and suppression of Itga1 expression. These findings provide new insights into the molecular basis of altered mechanosensing in ACM.

Heart failure is a morbid disorder characterized by progressive cardiomyocyte (CM) dysfunction and death. Interest in cell-based therapies is growing, but sustainability of injected CMs remains a challenge. To mitigate this, we developed an injectable biomimetic Reverse Thermal Gel (RTG) specifically engineered to support long-term CM survival. This RTG biopolymer provided a solution-based delivery vehicle of CMs, which transitioned to a gel-based matrix shortly after reaching body temperature. In this study we tested the suitability of this biopolymer to sustain CM viability. The RTG was biomolecule-functionalized with poly-l-lysine or laminin. Neonatal rat ventricular myocytes (NRVM) and adult rat ventricular myocytes (ARVM) were cultured in plain-RTG and biomolecule-functionalized-RTG both under 3-dimensional (3D) conditions. Traditional 2D biomolecule-coated dishes were used as controls. We found that the RTG-lysine stimulated NRVM to spread and form heart-like functional syncytia. Regarding cell contraction, in both RTG and RTG-lysine, beating cells were recorded after 21 days. Additionally, more than 50% (p value < 0.05; n = 5) viable ARVMs, characterized by a well-defined cardiac phenotype represented by sarcomeric cross-striations, were found in the RTG-laminin after 8 days. These results exhibit the tremendous potential of a minimally invasive CM transplantation through our designed RTG-cell therapy platform.

Objective Neurotrophins (NT) are a family of closely related proteins, including brain-derived neurotrophic factor, nerve growth factor, neurotrophin-3 (NT-3), and neurotrophin-4/5 (NT-4/5). NTs are deemed to regulate several aspects of neuronal survival, development, and function. Although NTs have been associated to a variety of mental disorders, the potential role of NT alterations in hypochondriasis (HC) has never been investigated. Methods In the present study, plasma concentrations of NTs were evaluated in 23 adult patients meeting Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, Text Revision criteria for HC and 22 healthy controls. Platelet serotonin (5-HT) content was chosen as a measure of serotonergic function. Hypochondriacal symptoms were assessed using the Whiteley Index of Hypochondriasis (WIH). Results Plasma NT-3 level ( P =.004) and platelet 5-HT ( P =.008) were significantly lower in patients with HC compared with controls. Correlation analyses showed that the WIH score was significantly and inversely associated with both NT-3 values ( r =−.60, P =.002) and platelet serotonin content ( r =−.53, P =.009). We used a multivariate regression model to determine independent predictors of the WIH score. After allowance for potential confounders, plasma NT-3 levels remained the unique independent predictor of the WIH ( β =.003, t =−3.5, P =.003). Conclusions Decreased NT-3 concentration, alongside with serotonin dysfunction, may represent a biological correlate of HC.

Few data are available regarding the prevalence of burnout among dialysis health care workers. Aims of the present study were to assess and compare burnout levels in a sample of nurses and physicians working in dialysis units, and to investigate their relationships with quality of life, in a cross-sectional observational study.A total of 344 workers from 10 dialysis centres in Northern Italy completed a battery of questionnaires including the Maslach Burnout Inventory, the MOS-36 Item Short Form Health Survey [SF36: physical (PCS) and mental (MCS) component scores] and the 30-item General Health Questionnaire (GHQ30). Data on social and demographic characteristics and working conditions were also collected. General Estimating Equations models were used for the analysis.Overall, burnout scores were lower than the Italian normative sample, with no significant differences between physicians and nurses. However, 30% of nurses had high emotional exhaustion vs 18% of physicians (adjusted OR 2.38, P = 0.003). Emotional exhaustion was also predicted by number of worked hours and months worked in dialysis in the previous 2 years. Depersonalisation was predicted by male gender and bad relationship with coworkers. Having no children and having a permanent hospital position predicted low personal accomplishment. PCS was lower in nurses (50.0 vs 53.3, P0.001), while no significant difference was found for MCS and GHQ30. Lower PCS was associated with emotional exhaustion (P = 0.007) and GHQ305 with depersonalization (P = 0.032).Although burnout is not a general problem in dialysis health care providers, a subgroup of them may be identified, who would benefit from supportive measures to prevent this condition. Nurses appeared more burned-out in the emotional exhaustion scale than physicians.

Arrhythmogenic cardiomyopathy (AC) is a genetic disease caused by mutations in genes encoding the intercalated disk (ID) proteins. ID is a multiprotein complex providing cell-cell junction and connecting the nucleus to the extracellular matrix, and playing a pivotal role for maintaining the structural integrity of the heart tissue. Mutations in PKP2 encoding plakophilin 2 (PKP2) are the most common causes of AC. The objective of this study was to investigate the biomechanical properties of the PKP2-knock down HL-1 mouse cardiac myocytes (PKP2-KD). PKP2 protein levels were reduced by 66 to 75% upon shRNA-targeting of the Pkp2 mRNA. Nuclear stiffness (Young’s modulus) and the force required to deform the nucleus were assessed by atomic force microscopy (AFM). Nuclear stiffness was decreased significantly (5 times) in PKP2-KD HL-1 myocytes as compared to wild-type (WT) myocytes, indicating an increased elasticity and/or susceptibility of the nucleus to be deformed (2 times). Interestingly, cell adhesion was also reduced (10 times) in the PKP2-KD myocytes, indicating a pivotal role of ID proteins in maintaining cell adhesion and mechanical integrity in cardiomyocytes. In the stress-relaxation test, while the decay time value was comparable between WT and PKP2-KD cells, relaxation force and cell deformation values were decreased 3 and 8 times, respectively, in PKP2-KD HL-1 myocytes, confirming the finding in the Young’s modulus. Moreover, the relaxation test revealed a reduced viscosity, highlighting a compromised cytoskeletal stability induced by the PKP2 deficiency. RNA-Sequencing and Ingenuity Canonical Pathway analysis identified integrin, tight junction, and the canonical Wnt signaling, among the most disturbed pathways in the PKP2-KD HL-1 myocytes. The findings indicate that the deficiency of a component of the ID protein markedly affects the whole-cellular biomechanics, which is expected to affect tissue stability, leading to activation of the mechano-transduction pathways.

Background: Advances in cell therapy and material science have made tissue engineering a promising strategy for heart regeneration. We developed an injectable biomimetic reverse thermal gel (RTG) that is liquid at room temperature but gel-like at body temperature, with the ultimate goal of being able to serve as a vehicle for cell-based delivery (liquid) to targeted tissue areas (gel-phase at 37°C). In this study we tested the suitability of this biomimetic RTG on cell viability. Methods and results: We tested different biomimetic RTG systems with and without the chemical incorporation of lysine. In vitro 3D culture experiments were performed with neonatal rat ventricular myocytes (NRVM) by mixing 3x104 cells with 50 μl of polymeric solution and allowing gel formation at 37°C. The cultured cells were incubated for 21 days. For controls we used NRVMs plated on 2D traditional gelatin coated dishes. We found that the 3D polymeric matrix induces rapid coordinated contraction with improved functionality when compared with standard 2D-cultured NRVM. By immunostaining for the morphology of the sarcomere (alpha-actinin) and DAPI, we also observed that the 3D polymeric matrix stimulates cells to spread and form 3D syncytia. Conclusion: These proof-of-concept results demonstrate long-term cell viability in this unique biomimetic system and therefore provide feasibility of a polymeric cell delivery system that permits reversible liquid-to-gel transition at body temperature. These results offer potential for a tissue engineering approach to cardiac regeneration.

The aim of this nested case-control study was to compare the effectiveness of cognitive-behavioral treatment (CBT) for treatment-resistant obese (body mass index [BMI] ≥ 30 kg/m²) women compared with standard dietary treatment. The main outcome measures were attrition and weight loss success.We designed a 6-month case-control study, nested within a cohort of adult (age ≥ 18 years) treatment-resistant (history of at least two previous diet attempts) obese women. Cases were 20 women who were offered CBT sessions. Controls (n=39) were randomly selected from the source population and matched to cases in terms of baseline age, BMI, and number of previous diet attempts.Compared with controls, cases were significantly more likely to complete the 6-month program in both age-adjusted (odds ratio [OR]=2.94, 95% confidence interval [CI]=1.05-8.97) and multivariate-adjusted (OR=2.77, 95% CI=1.02-8.34) analyses. In contrast, cases were not more likely to achieve weight loss success in age-adjusted (OR=1.32, 95% CI=0.86-1.67) and multivariate-adjusted (OR=1.21, 95% CI=0.91-1.44) analyses.Compared with a standard dietary treatment, CBT was significantly more effective in reducing attrition in treatment-resistant obese women, without differences in terms of weight loss success.

Objective Despite an improved quality of life, about 33% of heart transplant recipients will develop depressive symptoms post-operatively. To date, no review has explored the efficacy and safety of pharmacologic or psychologic interventions in this patient group. Methods We conducted a comprehensive Medline, EmBase, Psycinfo search for studies of the treatment of depression in heart transplant recipients. Results We identified 34 studies of variable methodologic quality. Selective serotonin re-uptake inhibitors (SSRIs), particularly citalopram and new-generation anti-depressants (mirtazapine), seem to represent the best therapeutic choices for this population. Tricyclic anti-depressants (TCAs), and electroconvulsive therapy (ECT) should be reserved for severe depression unresponsive to other treatments, whereas monoamine oxidase inhibitors (MAOIs) should be avoided. St John's wort, an alternative herbal drug, has been associated with life-threatening immunosuppression. Psychologic therapy offers further advantages after heart transplantation. Conclusions Further well-conducted, randomized, controlled trials are needed to clarify the efficacy and the safety of pharmacologic (SSRIs and atypical anti-depressants) and psychologic interventions in the management of depression after heart transplantation.

Background The purpose of this study was to advance current understanding of factors that influence long-term quality-of-life (QoL) outcomes after heart transplantation, by addressing the influence of depression on perceived health status. Methods Data were collected from all recipients ( n = 137) still alive at >10 years after transplantation. They completed the Short Form Health Survey (SF-36) inventory and the Beck Depression Inventory (BDI) questionnaire, while objective measures of health status were retrieved from medical records. All instruments used had acceptable reliability and validity. Data were analyzed using descriptive statistics, general linear regression models and survival analysis. Results We assessed 137 patients who received transplants between November 1985 and June 1994 in Pavia and have survived 10 to 18 years after transplantation (mean 13.64 years, SD 2.25). They rated their health as good and only the physical QoL (PCS) was impaired when compared with the general population. Thirty-two percent of patients experienced mood depressive symptoms in the long term after transplantation, indicating a low perceived QoL. Higher educational qualification ( p = 0.049), being unemployed and receiving a disability pension ( p = 0.001), high triglycerides levels ( p = 0.020) and lack of physical activity ( p Conclusions Assessment of depression levels and better understanding of risk factors for psychiatric disorders in the long term after transplantation could be of benefit in predicting negative outcomes and allowing future developments in patient management.

Atomic force microscopy (AFM) for single-cell force spectroscopy (SCFS) and Poisson statistic were used to analyze the detachment work recorded during the removal of gold-covered microspheres from cardiac fibroblasts. The effect of Cytochalasin D, a disruptor of the actin cytoskeleton, on cell adhesion was also tested. The adhesion work was assessed using a Poisson analysis also derived from single-cell force spectroscopy retracting curves. The use of Poisson analysis to get adhesion work from AFM curves is quite a novel method, and in this case, proved to be effective to study the short-range and long-range contributions to the adhesion work. This method avoids the difficult identification of minor peaks in the AFM retracting curves by creating what can be considered an average adhesion work. Even though the effect of actin depolymerisation is well documented, its use revealed that control cardiac fibroblasts (CT) exhibit a work of adhesion at least 5 times higher than that of the Cytochalasin treated cells. However, our results indicate that in both cells short-range and long-range contributions to the adhesion work are nearly equal and the same heterogeneity index describes both cells. Therefore, we infer that the different adhesion behaviors might be explained by the presence of fewer membrane adhesion molecules available at the AFM tip-cell interface under circumstances where the actin cytoskeleton has been disrupted.

AFM was used to collect the whole force-deformation cell curves. They provide both the elasticity and adhesion behavior of mouse primary cardiac fibroblasts. To confirm the hypothesis that a link exists between the membrane receptors and the cytoskeletal filaments causing therefore changing in both elasticity and adhesion behavior, actin-destabilizing Cytochalsin D was administrated to the fibroblasts. From immunofluorescence observation and AFM loading/unloading curves, cytoskeletal reorganization as well as a change in the elasticity and adhesion was indeed observed. Elasticity of control fibroblasts is three times higher than that for fibroblasts treated with 0.5 μM Cytochalasin. Moreover, AFM loading-unloading curves clearly show the different mechanical behavior of the two different cells analyzed: (i) for control cells the AFM cantilever rises during the dwell time while cells with Cytochalasin fail to show such an active resistance; (ii) the maximum force to deform control cells is quite higher and as far as adhesion is concern (iii) the maximum separation force, detachment area and the detachment process time are much larger for control compared to the Cytochalasin treated cells. Therefore, alterations in the cytoskeleton suggest that a link must exist between the membrane receptors and the cytoskeletal filaments beneath the cellular surface and inhibition of actin polymerization has effects on the whole cell mechanical behavior as well as adhesion.

Oral mucositis (OM) is a serious and acute side effect in patients with cancer who receive chemotherapy or radiotherapy, often leading to the suspension of therapy and a need for opioid analgesic and enteral/parenteral nutrition, with an effect on patient survival. Among the various interventions proposed in OM management, laser therapy is becoming a recommended treatment option but has limitations due to its heterogeneous laser parameters. Here, we report on our successful clinical experience on the use of class IV laser therapy to treat OM induced by different chemotherapy regimens. To shed light on the mechanisms of action of laser therapy in improving OM resolution, we have developed an animal model of chemotherapy-induced OM, in which we compare the efficacy of the standard low-power laser therapy protocol with an innovative protocol, defined as high-power laser therapy. We show that high-power laser therapy is more effective than low-power laser therapy in improving OM lesion healing, reducing the inflammatory burden, and preserving tissue integrity. In addition, high-power laser therapy has been particularly effective in promoting the formation of new arterioles within the granulation tissue. Our results provide important insights into the mechanism of action of biostimulating laser therapy on OM in vivo and pave a way for clinical experimentation with the use of high-power laser therapy.

The application of nanotechnology to the cardiovascular system has increasingly caught scientists' attention as a potentially powerful tool for the development of new generation devices able to interface, repair, or boost the performance of cardiac tissue. Carbon nanotubes (CNTs) are considered as promising materials for nanomedicine applications in general and have been recently tested toward excitable cell growth. CNTs are cylindrically shaped structures made up of rolled-up graphene sheets, with unique electrical, thermal, and mechanical properties, able to effectively conducting electrical current in electrochemical interfaces. CNTs-based scaffolds have been recently found to support the in vitro growth of cardiac cells: in particular, their ability to improve cardiomyocytes proliferation, maturation, and electrical behavior are making CNTs extremely attractive for the development and exploitation of interfaces able to impact on cardiac cells physiology and function.

Weight preoccupations have been frequently reported in normal-weight subjects. Subthreshold anorexia nervosa (s-AN, all DSM IV TR criteria except amenorrhea or underweight) is a form of eating disorder not otherwise specified that has received scarce scientific attention. Under a case-control design we compared the general characteristics, body composition, and psychopathological features of normal-weight patients with s-AN with those of BMI- and sex-matched controls.Participants in this pilot study included 9 normal-weight women who met the DSM IV TR criteria for s-AN and 18 BMI-matched normal-weight controls. The general characteristics of the study participants were collected by questionnaire. Body composition was measured by bioelectrical impedance. Behavioral and psychological measures included the standardized symptom checklist (SCL-90-R) and the eating disorder inventory (EDI-2).There were no differences in age, education, employment status, marital status, and history of previous slimming treatment in the two study groups. In addition, anthropometric measures and body composition of s-AN patients and BMI-matched normal weight controls were not significantly different. In the s-AN subgroup, we found a significant relationship between waist circumference and the SCL-90-R obsessivity-compulsivity scale (n=9, r=-0.69, p0.05). After multiple regression analysis, the SCL-90-R obsessivity-compulsivity scale (beta = 0.61, t=2.7, p=0.017) was the only independent predictor of the presence s-AN in our study cohort.These pilot results suggest that psychopathological criteria (particularly related to the obsessivity-compulsivity dimension) may be more useful than anthropometric measures for screening of s-AN in normal-weight women.

Background.This study examined the prevalence of students’ reported experiences of bullying and victimization in primary and secondary schools and their association with levels of perceived stress and cannabis use.Methods.We consecutively enrolled 407 students attending three secondary schools in Pavia (Italy). Bullying and victimization were measured using the retrospective bullying questionnaire (RQB). The 10-item perceived stress scale (PSS-10) was used to assess the degree to which situations in life were perceived as stressful. Data on demographic characteristics and cannabis use in the previous 6 months were also collected.Results.There were 328 victims (80.6%) and 221 bullies (52.1%). The results of the stepwise regression analysis with bullying as the dependent variable were significant with either male sex (R2 = 0.030,p = 0.024) or PSS-10 scores (R2 = 0.056,p = 0.036) in the model. With victimization as the dependent variable, only the PSS-10 scores were retained in the model as an independent predictor variable (R2 = 0.048,p Conclusions.The results from this study indicate that the level of perceived stress has an independent association with both bullying and victimization. Further studies are needed to clarify the psychobiological links between stress, cannabis use and bullying behaviours.

Recent years have witnessed numerous attempts at identifying the biological correlates of impending psychosis. Biochemical markers may theoretically provide a powerful approach to identify at-risk individuals, potentially leading to more effective intervention strategies to treat them. Hopefully, future developments in the field of research biochemistry in patients with at risk mental states or prodromal symptoms will make this approach ideal for screening and monitoring purposes. In this review, we provide an overview of the different biochemical markers which have been recently demonstrated to be altered in the biological fluids of patients with impending psychosis. We will also examine the practical issues that seem to be limiting the effective integration of biomarkers into clinical development.

Evidence suggests that psychiatric patients are at an increased vascular risk. In this exploratory pilot study, we hypothesized that low levels of the soluble receptor for advanced glycation endproducts (sRAGE) might be found in psychiatric patients due to its association with atherothrombosis. We recruited 74 patients with different psychiatric disorders (39 schizophrenia, 10 major depression, 13 bipolar disorder and 12 personality disorder) and 74 healthy controls. Serum levels of sRAGE were determined by enzyme-linked immunosorbant assay. In univariate analysis, serum sRAGE levels of the patient groups with schizophrenia, major depression and bipolar disorder were significantly lower than that of the control group. The median sRAGE levels of these diagnostic groups were comparable with those reported in patients with prior atherothrombotic events. After allowance for potential confounders, the odds of reduced sRAGE remained independently associated with schizophrenia and major depression. Although subject to future confirmation, our findings suggest that the reduced serum sRAGE may contribute to increased cardiovascular risk in schizophrenia and major depression.

Previous studies have suggested that the endogeneous psychotomimetic molecule bufotenine (N-N-dimethyl-5-idroxytryptamine) may play a role in the pathogenesis of severe mental disorders. The potential association of bufotenine with the clinical features of autism and schizophrenia is not entirely understood. In this study, we measured urinary levels of bufotenine in subjects with autistic spectrum disorder (ASD), schizophrenia and healthy comparison subjects free of psychiatric symptoms. We also sought to assess whether urine concentrations of this molecule may be associated with the clinical characteristics of psychiatric patients.Urine bufotenine levels were measured using a high-performance liquid chromatography-mass spectrometry (HPLC-MS) assay in young adults with severe ASD (n=15), patients with schizophrenia (n=15), and healthy control subjects (n=18). The Vineland Adaptive Behavior Scale was used to measure adaptive behaviors in ASD individuals. The Brief Psychiatric Rating Scale (BPRS) was used for patients with schizophrenia.Urine bufotenine levels were significantly higher in ASD subjects (3.30 +/- 0.49 microg/L, p0.05) and patients with schizophrenia (4.39 +/- 0.43 microg/L, p0.001) compared with controls (1.53 +/- 0.30 microg/L). Among patients with ASD, there was a significant positive correlation between urine bufotenine and hyperactivity scores on the Vineland Adaptive Behavior Scale (r=0.479, p0.05). No other associations were detected.Our results indicate that elevated urine levels of the endogeneous psychotomimetic molecule bufotenine may play a role in ASD and schizophrenia, and can be correlated with hyperactivity scores in autism.

Background Limited research has been done on depression and quality of life in long-term survival after heart transplantation. The aim of the present study was to investigate the role of age on depression and quality of life in a sample of long-term heart transplant recipients. Methods We investigated 137 consecutive patients recruited in a single center who were still alive at more than 10 years after transplantation. Quality of life and depression were rated with the Medical Outcome Study Short Form (SF-36) and the Beck Depression Inventory (BDI), respectively. Sociodemographic, clinical, affective, and quality of life data for long-term survival patients stratified by current age younger than 70 years (young) and 70 years or older (old) were compared using Fisher’s exact tests and Student’s t-tests. Results The SF-36 Mental Component Summary did not significantly differ between the young subjects (48.75 ± 10.2) compared with old (48.47 ± 10.1; p = 0.897). By contrast, the SF-36 Physical Component Summary was higher in younger subjects (46.88 ± 10.2 vs 40.81 ± 10.6, p = 0.008). According to BDI, 37.4% of the young group and 13.3% of the old group scored above the selected threshold of 10 (p = 0.014). Conclusions In the light of our findings, older age does not seem to negatively affect the mental component of quality of life in the long term after heart transplantation, but it does on the physical component, as expected. On the other hand, it may be even associated with a lower prevalence of depressive symptoms more than 10 years after surgery. Hence, age per se does not represent a major limiting factor when considering candidates for this procedure, at least with regard to the issue of psychologic distress.

Dipeptidyl peptidase IV (DPPIV or CD26) is an ubiquitously expressed protease that could play a role in the pathogenesis of anxiety in view of its capacity to cleave several behaviourally active neuropeptides. Hereto we sought to determine the relationship between phobic anxiety, as measured by the Crown-Crisp index, and circulating levels of soluble CD26 (sCD26) in a large cohort of 1017 Italian women participating in a general health survey. The association between sCD26 levels and phobic anxiety was tested using simple correlation analysis, linear regression and multivariate logistic regression analysis. A highly significant inverse association was found between sCD26 concentrations and anxiety scores both in simple correlation and linear regression analysis. Compared with subjects in the first tertile of sCD26 levels, the age-adjusted odds ratio for scoring >/=6 compared to scoring 0 or 1 was 0.31 (95% CI: 0.18-0.74) for the second and 0.47 (95% CI: 0.34-0.63) for the third tertile. Altogether, our data suggest that reduced plasma sCD26 concentrations could be a marker of high levels of phobic anxiety in women.

The zinc metalloenzyme glyoxalase I (GLO1) is thought to play a role in anxiety disorders because a reduced brain expression of GLO1 has been associated with increased anxiety-behaviours in mice. Recently, a functional Ala111Glu polymorphism in GLO1 has been shown to result in a reduced enzyme activity. The present study tested the hypothesis that this common genetic variant could confer susceptibility to panic disorder using an Italian population sample of 162 panic disorder patients and 288 matched controls. Statistical analysis failed to show association with the overall diagnosis of the disease. However, a weak but significant association was demonstrated between this polymorphism and panic disorder without agoraphobia. While our data suggest that this polymorphism is unlikely to have a major function in the pathogenesis of panic disorder, it could play a role in the subgroup of patients without agoraphobic avoidance.

Objective High levels of neuroticism and low self-esteem are markers for vulnerability to depression, a condition associated with a higher risk of arrhythmias. The question as to whether these depression-related personality domains are related to cardiac repolarization (duration of QT interval) in apparently healthy men has been addressed in this study. Methods Participants were 658 clinically healthy males who underwent a health screening programme. QT interval duration was determined in the resting 12-lead electrocardiogram using an automated analysis program. Neuroticism was assessed by the short-scale Eysenck Personality Questionnaire and self-esteem by the Rosenberg self-esteem scale. Results Heart-rate corrected QT interval {QTc, formula of Bazett [Bazett HC. An analysis of time relations of electrocardiograms. Heart 1920;7:353–370]} progressively increased across quartiles of neuroticism ratings. By contrast, no differences in QTc were observed across different degrees of self-esteem. A multivariate regression analysis showed that neuroticism was a statistically significant, independent predictor of QTc duration. Conclusion After adjustment for potential confounders, neuroticism scores independently predicted QT interval duration in apparently healthy men. These findings highlight the possibility that higher arrhythmic risk could be present not only in patients with clinical depression but also in depression-prone, otherwise healthy individuals.

Ankrd2 may be a link between the sarcomere and the nucleus; a similar role has recently been proposed for CARP that has a high level of structural and functional conservation with Ankrd2. Both Ankrd2 and CARP are involved in striated muscle hypertrophy. The mechanism by which muscle stretch is sensed and signals are transduced is still unknown; however, Ankrd2 and CARP could play similar roles in pathways leading to hypertrophy, the triggering mechanisms being heart pressure overload monitored by CARP and mechanical stretch in skeletal muscle monitored by Ankrd2. Recently Ankrd2 and CARP have been proposed as members of a family of muscle ankyrin repeat proteins (MARPs) that form a complex with titin, myopalladin and calpain protease p94, involved in signaling and regulation of gene expression in response to muscle stress. Here, we show that Ankrd2 is able to interact with the Z-disc protein telethonin as well as being able to interact with three transcription factors: YB-1, PML and p53. Ankrd2 binding to the ubiquitous transcription factor YB-1 can be demonstrated both in vitro and in vivo; this is not very surprising, since a similar interaction was previously described for CARP. However, the interactions with PML and p53 are unexpected new findings, with interesting implications in the Ankrd2 signaling cascade. Ankrd2 co-localizes with the transcriptional co-activator and co-repressor PML in nuclear bodies (NBs) in human myoblasts as detected by confocal immunofluorescence. Interestingly, we show that Ankrd2 not only binds the tumor suppressor protein p53 both in vitro and in vivo but also enhances the up-regulation of the p21(WAFI/CIPI) promoter by p53. Therefore, our findings strengthen the hypothesis that Ankrd2 may be involved in sensing stress signals and linking these to muscle gene regulation.
