White matter hyperintensities and self-reported depression in a sample of patients with chronic headache

White matter hyperintensities (WMH) have been associated with mood disorders in psychiatric patients. In the present study, we aimed to assess whether WMHs are associated with depressive symptoms and different sensitivity of the behavioral inhibition (BIS), and activation (BAS) systems in patients with chronic headache. Participants were 85 adult outpatients (16 men and 69 women) with a diagnosis of chronic headache. All of the patients underwent brain magnetic resonance imaging (MRI) and were administered the BIS/BAS scales and the Center for Epidemiologic Studies Depression Scale. Above 40 % of patients had periventricular WMHs (PWMHs) and almost 98 % had deep WMHs (DWMHs). Patients with PWMHs reported fewer depressive symptoms than patients without PWMHs. Patients with more severe DWMHs (compared with patients with mild or without DWMH lesions) were older and reported lower scores on the drive dimension of the BIS/BAS scales. In multivariate analyses, patients with PWMHs were 1.06 times more likely to report fewer depressive symptoms than patients without PWMHs. WMH lesions in patients with chronic headache were associated with less depression severity

Runx2 stimulates neoangiogenesis through the Runt domain in melanoma

Runx2 is a transcription factor involved in melanoma cell migration and proliferation. Here, we extended the analysis of Runt domain of Runx2 in melanoma cells to deepen understanding of the underlying mechanisms. By the CRISPR/Cas9 system we generated the Runt KO melanoma cells 3G8. Interestingly, the proteome analysis showed a specific protein signature of 3G8 cells related to apoptosis and migration, and pointed out the involvement of Runt domain in the neoangiogenesis process. Among the proteins implicated in angiogenesis we identified fatty acid synthase, chloride intracellular channel protein-4, heat shock protein beta-1, Rho guanine nucleotide exchange factor 1, D-3-phosphoglycerate dehydrogenase, myosin-1c and caveolin-1. Upon querying the TCGA provisional database for melanoma, the genes related to these proteins were found altered in 51.36% of total patients. In addition, VEGF gene expression was reduced in 3G8 as compared to A375 cells; and HUVEC co-cultured with 3G8 cells expressed lower levels of CD105 and CD31 neoangiogenetic markers. Furthermore, the tube formation assay revealed down-regulation of capillary-like structures in HUVEC co-cultured with 3G8 in comparison to those with A375 cells. These findings provide new insight into Runx2 molecular details which can be crucial to possibly propose it as an oncotarget of melanoma

The association among childhood trauma, pathological dissociation and gambling severity in casino gamblers

The aim of the present study was to explore the role of pathological dissociation in mediating the association between childhood trauma (CT) and gambling severity. One hundred seventy-one (134 men and 37 women) gamblers recruited in gambling environments (i.e., two Italian casinos) have been enrolled in the study. Psychopathological assessments included the Childhood Trauma Questionnaire (CTQ), the Dissociative Experiences Scale-Taxon (DES-T), the South Oaks Gambling Screen (SOGS), the CAGE and the Hospital Anxiety and Depression Scale. A mediational model, analyzing the direct and indirect effects of CTQ on SOGS through the mediating role of DES-T, showed that the relation between CTQ and SOGS was fully mediated by DES-T scores (b = 0.07; se = 0.15; p < 0.001). This finding raises the possibility that CT explains gambling severity through the presence of pathological dissociative symptoms and dissociative pathogenetic processes. Copyright © 2015 John Wiley & Sons, Ltd. Key Practitioner Message: Gambling severity is associated with both childhood trauma and pathological dissociation in casino gamblers. A mediational model shows that the effect of childhood trauma on gambling severity is entirely mediated by pathological dissociation. From a clinical point of view, our results highlight the importance of assessing, and possibly treating, dissociative symptoms in individuals with gambling disorder

Circulating tumour DNA: a challenging innovation to develop "precision onco-surgery" in pancreatic adenocarcinoma

: Pancreatic ductal adenocarcinoma (PDAC) is predicted to become the third leading cause of cancer-related mortality within the next decade. Management of PDAC remains challenging with limited effective treatment options and a dismal long-term prognosis. Liquid biopsy and circulating biomarkers seem to be promising to improve the multidisciplinary approach in PDAC treatment. Circulating tumour DNA (ctDNA) is the most studied blood liquid biopsy analyte and can provide insight into the molecular profile and individual characteristics of the tumour in real-time and in advance of standard imaging modalities. This could pave the way for identifying new therapeutic targets and markers of tumour response to supplement diagnostic and provide enhanced stratified treatment. Although its specificity seems excellent, the current sensitivity of ctDNA remains a limitation for clinical use, especially in patients with a low tumour burden. Increasing evidence suggests that ctDNA is a pertinent candidate biomarker to assess minimal residual disease after surgery but also a strong independent prognostic biomarker. This review explores the current knowledge and recent developments in ctDNA as a screening, diagnostic, prognostic and predictive biomarker in the management of resectable PDAC but also technical and analytical challenges that must be overcome to move toward "precision onco-surgery.

High Values of Drain Fluid Epidermal Growth Factor and Transforming Growth Factor-beta are Associated with the Development of Pancreatic Fistula after Pancreatoduodenectomy

Introduction: Postoperative inflammatory response may act as a major determinant of anastomotic failure after pancreaticoduodenectomy. In this pilot study, we investigated the potential role of drain fluid cytokines in predicting postoperative pancreatic fistula (POPF). Methods Drain fluid TGF-β, IGF-1, EGF and IL-6, together with serum amylase and drain fluid amylase were measured on POD1 and correlated to the development of POPF. Results The study population consisted of 66 patients. POPF and Clavien-Dindo 3 morbidity rates were 12.1% and 9.1%, respectively. Patients developing POPF presented significantly higher values of POD1 serum amylase level (477 vs 54UI/L, p&lt; 0.001), drain fluid amylase (7500 vs. 127UI/L, p&lt; 0.001), TGF (94 vs. 40pg/g, p= 0.045) and EGF (17 vs. 13, p= 0.015). There were no differences in terms of IGF-1 and IL-6 values. Conclusion Assessing the local inflammatory response after pancreatoduodenectomy could represent a promising field of research since both TGF and EGF seem to be associated with the occurrence of POPF

Temperament, Post-Partum Depression, Hopelessness, and Suicide Risk Among Women Soon After Delivering

The aim of the authors in this study was to assess the prevalence of postpartum depression and evaluate the association of affective temperaments with emotional disorders in a sample of 92 pregnant women consecutively admitted for delivery between March and December 2009. In the first few days postpartum, women completed the Suicidal History Self-rating Screening Scale, the Beck Hopelessness Scale, the Edinburgh Postnatal Depression Scale, the Temperament Evaluation of the Memphis, Pisa, Paris and San Diego Autoquestionnaire, and the Gotland Male Depression Scale. Fifty percent of the women reported an Edinburgh Postnatal Depression Scale score of 9 or higher, and 23% a score of 13 or higher. Women with a dysphoric-dysregulated temperament had higher mean scores on the Beck Hopelessness Scale (p < 0.05), the Gotland Male Depression Scale (p < 0.001), the Edinburgh Postnatal Depression Scale (p < 0.001), and the Suicidal History Self-Rating Screening Scale (p < 0.01) than other women after adjusting for covariates. Multiple logistic regression analysis with the temperament groups as the dependent variable indicated that only the Gotland Male Depression Scale was significantly associated with temperament when controlling for the presence of other variables. Women with a dysphoric-dysregulated temperament were 1.23 times as likely to have higher depressive symptom scores. Future studies should evaluate the effectiveness of psychiatric screening programs in the postpartum period as well as factors associated with depression and suicidality during the same period

La stagione neorealistica di Eduardo tra la scena e lo schermo

Il saggio si occupa di quella felice stagione del secondo dopoguerra durante la quale Eduardo scrisse i suoi capolavori teatrali e realizzò la maggior parte delle sue opere cinematografiche. Cerca inoltre di chiarie due equivoci che hanno inficiato una serena valutazione critica del suo rapporto con lo schermo. La prima è il contributo al “neorealismo”, inteso come uno schema prefissato a cui gli autori, come lo stesso Eduardo, dovevano attenersi. Il secondo equivoco è legato ad una vulgata che mette a confronto i due ambiti: la scena e lo schermo finendo per concludere che la sua figura di cineasta sia mediocre. Eduardo, in breve, diede un valido contributo alla stagione neorealista, nel cinema, non meno che nel teatro. Per quanto riguarda le sue capacità di attore e anche di regista, ad una più attenta e meditata analisi, si rivelano caratteri fin ad ora ignorati di originalità e resa espressiva
