Raising awareness on gender issues: A path through physics, outreach and diversity.

When and where it is convenient to start working on raising awareness on gender issues? Our answer is that high school is definitely a good start, mainly if we think that outreach activities can have a role in the transition to an environment for learning, teaching and researching in physics that is equally attractive and supportive to all genders, at each stage of their education and career path. As researchers of INFN and CNR we promoted a school competition devoted to consider the role of women in science and particularly in Physics. Outreach activities can have the role of raising awareness, knowledge through an active involvement of students for changing the culture and removing stereotypes. In these years we organized 3 contests, with 226 videos, more than 100 high schools and a thousand of students involved. The idea was to try to understand the thinking and knowledge of young people on present and past gender issues connected to women and science, to know how they imagine the society of the future, to understand if they are unaware "carriers" of stereotypes and prejudices and if the cultural change can start from/with them. The students have been asked to produce a video on subjects regarding these questions. The article describes the contests, the evaluation process, the results of first analysis. The work started inside the EU-funded GENERA project, to which both research groups belong, and continues inside the GENERA Network. The collaboration among physicists and sociologists has been, and still is, fundamental in these years

Clinical features and outcomes of elderly hospitalised patients with chronic obstructive pulmonary disease, heart failure or both

Background and objective: Chronic obstructive pulmonary disease (COPD) and heart failure (HF) mutually increase the risk of being present in the same patient, especially if older. Whether or not this coexistence may be associated with a worse prognosis is debated. Therefore, employing data derived from the REPOSI register, we evaluated the clinical features and outcomes in a population of elderly patients admitted to internal medicine wards and having COPD, HF or COPD + HF. Methods: We measured socio-demographic and anthropometric characteristics, severity and prevalence of comorbidities, clinical and laboratory features during hospitalization, mood disorders, functional independence, drug prescriptions and discharge destination. The primary study outcome was the risk of death. Results: We considered 2,343 elderly hospitalized patients (median age 81 years), of whom 1,154 (49%) had COPD, 813 (35%) HF, and 376 (16%) COPD + HF. Patients with COPD + HF had different characteristics than those with COPD or HF, such as a higher prevalence of previous hospitalizations, comorbidities (especially chronic kidney disease), higher respiratory rate at admission and number of prescribed drugs. Patients with COPD + HF (hazard ratio HR 1.74, 95% confidence intervals CI 1.16-2.61) and patients with dementia (HR 1.75, 95% CI 1.06-2.90) had a higher risk of death at one year. The Kaplan-Meier curves showed a higher mortality risk in the group of patients with COPD + HF for all causes (p = 0.010), respiratory causes (p = 0.006), cardiovascular causes (p = 0.046) and respiratory plus cardiovascular causes (p = 0.009). Conclusion: In this real-life cohort of hospitalized elderly patients, the coexistence of COPD and HF significantly worsened prognosis at one year. This finding may help to better define the care needs of this population

Psychopathology, body uneasiness and self-identity in patients with non-BED obesity compared to healthy controls

Introduction: Obesity represents a major public health problem associated with medical and psychological impairment. Obesity is frequently studied with Binge Eating Disorder (BED) comorbidity. Less evidence is available for non-BED obesity, in spite of its correlation with psychological impairment and body image disturbance. In this study, we explored psychopathological features, eating behaviors, body image disturbance and self-identity impairment in patients with obesity and a control group. In patients, we also studied the relation between specific eating/body features and psychopathological symptoms. Finally, we explored the latent factorial structure that describes these features. Material and methods: The clinical sample was composed by twenty patients suffering from obesity without BED (16 females). The control group included twenty-eight healthy and normal-weight subjects (20 females) enrolled from the general population. All participants underwent a clinical interview and filled out questionnaires about body image and psychopathological symptoms. Statistics: The Student t test was applied to compare obese patients and healthy controls in all psychological dimensions. In the clinical sample, gender differences were tested through multivariate analyses of variance (MANOVA). Then, correlational analyses explored the relation between specific eating/body features and psychopathological symptoms. Lastly, a principal-components factor analysis was performed to explore the existence of a latent factorial structure emerging from assessment evaluation in obese population. Results: Obese patients reported significantly higher scores than healthy controls in several psychopathological dimensions, i.e. Somatization, Obsessive-Compulsive, Depression, Hostility, Phobic Anxiety, and Psychoticism. Patients also reported higher body uneasiness and self-identity impairment resulting from some scores on Body Uneasiness Test and Identity and Eating Disorders questionnaire. Avoidant behaviours were more frequently reported in men whereas women reported higher body distress/dissatisfaction. In the clinical sample the questionnaires were correlated and a three-factor structure emerged: “Weight and body control”, “Weakness of Self-Identity”, and “Psychopathological distress”. Discussion: The present study found that obese patients might present several disturbances in body image, self- perception and general psychopathological distress. Clinicians should be aware of these issues to improve therapeutic strategy in the treatment of obesity

Italian normative data for a stroke specific cognitive screening tool: the Oxford Cognitive Screen (OCS)

Cognitive deficits occur in most stroke patients and cognitive impairment is an important predictor of adverse long term outcome. However, current screening measures, such as the Mini Mental State Examination or the Montreal Cognitive Assessment, do not provide information tuned for evaluating the impact of cognitive impairment in the early phase after stroke. The Oxford Cognitive Screen (OCS) represents an important new development in this regard. The OCS is now available for assessment of Italian individuals and the aim of this study is to standardize the OCS on a large sample of healthy Italian participants stratified for age, gender and education level. Results confirmed the influence of these factors in several of the OCS tasks. Age-, education- and gender-adjusted norms are provided for the ten sub-tests of the test. The availability of normative data represents an important prerequite for the reliable use of OCS with stroke patients

GABAergic miR-34a regulates Dorsal Raphè inhibitory transmission in response to aversive, but not rewarding, stimuli

The brain employs distinct circuitries to encode positive and negative valence stimuli, and dysfunctions of these neuronal circuits have a key role in the etiopathogenesis of many psychiatric disorders. The Dorsal Raphè Nucleus (DRN) is involved in various behaviors and drives the emotional response to rewarding and aversive experiences. Whether specific subpopulations of neurons within the DRN encode these behaviors with different valence is still unknown. Notably, microRNA expression in the mammalian brain is characterized by tissue and neuronal specificity, suggesting that it might play a role in cell and circuit functionality. However, this specificity has not been fully exploited. Here, we demonstrate that microRNA-34a (miR-34a) is selectively expressed in a subpopulation of GABAergic neurons of the ventrolateral DRN. Moreover, we report that acute exposure to both aversive (restraint stress) and rewarding (chocolate) stimuli reduces GABA release in the DRN, an effect prevented by the inactivation of DRN miR-34a or its genetic deletion in GABAergic neurons in aversive but not rewarding conditions. Finally, miR-34a inhibition selectively reduced passive coping with severe stressors. These data support a role of miR-34a in regulating GABAergic neurotransmitter activity and behavior in a context-dependent manner and suggest that microRNAs could represent a functional signature of specific neuronal subpopulations with valence-specific activity in the brain

The largest western experience on salvage hepatectomy for recurrent hepatocellular carcinoma: propensity score-matched analysis on behalf of He.RC.O.Le.Study Group

BackgroundWe aimed to evaluate, in a large Western cohort, perioperative and long-term oncological outcomes of salvage hepatectomy (SH) for recurrent hepatocellular carcinoma (rHCC) after primary hepatectomy (PH) or locoregional treatments.MethodsData were collected from the Hepatocarcinoma Recurrence on the Liver Study Group (He.RC.O.Le.S.) Italian Registry. After 1:1 propensity score-matched analysis (PSM), two groups were compared: the PH group (patients submitted to resection for a first HCC) and the SH group (patients resected for intrahepatic rHCC after previous HCC-related treatments).Results2689 patients were enrolled. PH included 2339 patients, SH 350. After PSM, 263 patients were selected in each group with major resected nodule median size, intraoperative blood loss and minimally invasive approach significantly lower in the SH group. Long-term outcomes were compared, with no difference in OS and DFS. Univariate and multivariate analyses revealed only microvascular invasion as an independent prognostic factor for OS.ConclusionSH proved to be equivalent to PH in terms of safety, feasibility and long-term outcomes, consistent with data gathered from East Asia. In the awaiting of reliable treatment-allocating algorithms for rHCC, SH appears to be a suitable alternative in patients fit for surgery, regardless of the previous therapeutic modality implemented

Amygdalofrontal Functional Disconnectivity and Aggression in Schizophrenia

A significant proportion of patients with schizophrenia demonstrate abnormalities in dorsal prefrontal regions including the dorsolateral prefrontal and dorsal anterior cingulate cortices. However, it is less clear to what extent abnormalities are exhibited in ventral prefrontal and limbic regions, despite their involvement in social cognitive dysfunction and aggression, which represent problem domains for patients with schizophrenia. Previously, we found that reduced white matter integrity in right inferior frontal regions was associated with higher levels of aggression. Here, we used resting-state functional magnetic resonance imaging to examine amygdala/ventral prefrontal cortex (vPFC) functional connectivity (FC) and its relation to aggression in schizophrenia. Twenty-one healthy controls and 25 patients with schizophrenia or schizoaffective disorder participated. Aggression was measured using the Buss Perry Aggression Questionnaire. Regions of interest were placed in the amygdala based on previously published work. A voxelwise FC analysis was performed in which the mean time series across voxels for this bilateral amygdala seed was entered as a predictor in a multiple regression model with motion parameters and global, cerebrospinal fluid, and white matter signals as covariates. Patients showed significant reductions in FC between amygdala and vPFC regions. Moreover, in patients, the strength of this connection showed a significant inverse relationship with aggression, such that lower FC was associated with higher levels of self-rated aggression. Similar results were obtained for 2 other measures—Life History of Aggression and total arrests. These results suggest that amygdala/vPFC FC is compromised in schizophrenia and that this compromise is associated with aggression

Partial asynchrony of coniferous forest carbon sources and sinks at the intra-annual time scale.

Funder: Fonds de Recherche du Québec - Nature et Technologies (FRQNT)As major terrestrial carbon sinks, forests play an important role in mitigating climate change. The relationship between the seasonal uptake of carbon and its allocation to woody biomass remains poorly understood, leaving a significant gap in our capacity to predict carbon sequestration by forests. Here, we compare the intra-annual dynamics of carbon fluxes and wood formation across the Northern hemisphere, from carbon assimilation and the formation of non-structural carbon compounds to their incorporation in woody tissues. We show temporally coupled seasonal peaks of carbon assimilation (GPP) and wood cell differentiation, while the two processes are substantially decoupled during off-peak periods. Peaks of cambial activity occur substantially earlier compared to GPP, suggesting the buffer role of non-structural carbohydrates between the processes of carbon assimilation and allocation to wood. Our findings suggest that high-resolution seasonal data of ecosystem carbon fluxes, wood formation and the associated physiological processes may reduce uncertainties in carbon source-sink relationships at different spatial scales, from stand to ecosystem levels
