Clinical and personality profile of depressed suicide attempters: A preliminary study at the open-door policy Mood Disorder Unit of San Raffaele Hospital.

Suicidal behavior is a complex phenomenon with high rates among psychiatric inpatients. Mood disorders and personality dysfunctions represent relevant risk factors for suicides attempts and suicidal ideation. Our study aims to investigate the role of the co-occurrence of clinical variables (duration of depressive state, previous suicide attempts), socio-demographic variables (gender, employment and civil status) and narcissistic personality features in the suicide risk of admitted psychiatric patients affected by a mood disorder. The sample was composed of 93 patients consecutively admitted in an open ward psychiatric Unit. Forty-eight participants had a positive history of previous suicide attempts: the suicide attempters (SA) were mostly female, unemployed and married. The SA group were observed to have suffered from a depressive episode with a longer duration; moreover in the SA group, the presence of active suicidal ideation was significantly related to a higher number of previous suicide attempts. In the whole sample, suicidal ideation was significantly related to narcissistic vulnerability personality features. Using a multidimensional approach, the present study allows a preliminary profiling of patients at risk for suicidal behavior during hospitalization.

Real-Time Observation of Phonon-Mediated σ-π Interband Scattering in MgB_{2}.

In systems having an anisotropic electronic structure, such as the layered materials graphite, graphene, and cuprates, impulsive light excitation can coherently stimulate specific bosonic modes, with exotic consequences for the emergent electronic properties. Here we show that the population of E_{2g} phonons in the multiband superconductor MgB_{2} can be selectively enhanced by femtosecond laser pulses, leading to a transient control of the number of carriers in the σ-electronic subsystem. The nonequilibrium evolution of the material optical constants is followed in the spectral region sensitive to both the a- and c-axis plasma frequencies and modeled theoretically, revealing the details of the σ-π interband scattering mechanism in MgB_{2}.

Voice disorders in primary school teachers.

Previous reports focusing on the high prevalence of voice disorders in teachers have suggested that vocal loading might be the main causal factor. The aim of our study was to assess the prevalence of voice disorders in a sample of primary school teachers and evaluate possible cofactors. Our sample was composed of 157 teachers (155 females, mean age 46 years). Participants were asked to complete two selfadministrated questionnaires: one with clinical data, and the second an Italian validated translation of VHI (voice handicap index). On the same day they also underwent a laryngostroboscopic exam and logopedic evaluation. The results were compared with those of a control group composed of accompanying individuals. Teachers presented a higher rate of abnormalities at laryngostroboscopic examination than the control group (51.6% vs. 16%, respectively). Among these, 7.1% presented nodules. In our sample, vocal fold disorders were not correlated with years of teaching, smoking, coffee consumption, or levels of anxiety. Our findings are in agreement with previous reports on the prevalence of pathologic disorders among teachers; nonetheless, the prevalence of nodules was lower than in previous investigations, and voice loading was not correlated with laryngostroboscopic findings. Current Italian law does not include any guidance regarding voice education and screening in subjects with high vocal loading. Our work stresses the need for such legislation.
