RESUMO

Treatment resistant (TR) psychosis is considered to be a significant cause of disability and functional impairment. Numerous efforts have been made to identify the clinical predictors of TR. However, the exploration of molecular and biological markers is still at an early stage. To understand the TR condition and identify potential molecular and biological markers, we analyzed demographic information, clinical data, structural brain imaging data, and molecular brain imaging data in 7 Tesla magnetic resonance spectroscopy from a first episode psychosis cohort that includes 136 patients. Age, gender, race, smoking status, duration of illness, and antipsychotic dosages were controlled in the analyses. We found that TR patients had a younger age at onset, more hospitalizations, more severe negative symptoms, a reduction in the volumes of the hippocampus (HP) and superior frontal gyrus (SFG), and a reduction in glutathione (GSH) levels in the anterior cingulate cortex (ACC), when compared to non-TR patients. The combination of multiple markers provided a better classification between TR and non-TR patients compared to any individual marker. Our study shows that ACC-GSH, HP and SFG volumes, and age at onset, could potentially be biomarkers for TR diagnosis, while hospitalization and negative symptoms could be used to evaluate the progression of the disease. Multimodal cohorts are essential in obtaining a comprehensive understanding of brain disorders.

RESUMO

BACKGROUND: Objective of the present manuscript is to investigate, among Italian early career psychiatrists (ECPs), prescriber and patient-related factors associated with lithium or valproate preference to treat patients affected by Bipolar Disorder (BD). METHODS: An on-line survey was carried out among 252 ECPs, investigating their prescription patterns in relation to lithium and the differences with prescription of valproate. Collected data were compared according to lithium or valproate prescription preference in the long-term treatment of BD by χ2 tests for qualitative variables. RESULTS: Over two thirds of ECPs preferred lithium over valproate for the maintenance treatment of BD. Less than half of the sample used lithium as first-line agent for mania or major depression, and less than one third for mixed episodes. Factors associated with lithium preference as first-line maintenance treatment include perception of having a good knowledge of lithium (p < 0.001) and complete satisfaction with education on lithium (p < 0.001). One of the main factors to prefer valproate was the concern about long-term side effects of lithium (p < 0.001). CONCLUSIONS: Type of education, source of information, clinical experience and safety concerns influence the choice of lithium versus valproate in the long-term treatment of BD. Present findings may guide educational training of ECPs.KEY POINTSLithium has been less prescribed in the last years for long-term treatment of Bipolar Disorder.Educational and clinical factors seem to influence the attitude to prescribe lithium.Only half of the Italian early career psychiatrists declare to have at least an adequate knowledge of lithium.Residency program in psychiatry should consider the implementation of education on lithium.

RESUMO

The aim of this study was to analyze protein and gene expression of HER2 in 224 head and neck precancerous and malignant lesions by immunohistochemistry and FISH analysis. In parallel, expression of pStat3, Sox2, IFI16 and p16, Ki67 was evaluated. Immunohistochemical analysis was assessed on formalin-fixed paraffin-embedded (FFPE) tissue specimens. A combined method for HPV detection consisting of p16 immunostaining and two PCR probes was applied. HER2 gene status was evaluated by FISH analysis. HPV DNA was detected in 24% of cases with predominant HPV16 genotype. HPV-positive lesions had higher HER2, pStat3 and within carcinoma group, and higher IFI16 expression compared to the HPV-negative group (Fig. 1A-B-C). A strong positive correlation between Sox2 and proliferative activity was observed, whereas IFI16 expression displayed a negative relationship with Sox2 and Ki67 activity. The most striking result was higher pStat3 expression in HPV-positive lesions and its strong positive correlation with IFI16 expression. The presence of HPV may induce upregulation of HER2/neu, pStat3 and IFI16. High levels and a strong positive correlation between pStat3 and IFI16 suggest their synergistic pro-apoptotic effects in HPV-positive lesions.

RESUMO

The training of mental health professionals is an important component of suicide-prevention programs. A cross-sectional survey was conducted in different Italian regions to evaluate knowledge of, and attitudes toward, suicide as well as the experience of a patient's suicide or a suicide attempt in early career psychiatrists (ECPs) and trainees (N = 338). The Suicide Knowledge and Skills Questionnaire and the Impact of a Patient's Suicide on Professional and Personal Lives scale were administered. Furthermore, symptoms of intrusion, avoidance, and arousal were examined through the Impact of Event Scale in ECPs and trainees who had experienced the suicide of a patient or a suicide attempt. Participants with training were more confident in the clinical management of suicide-risk patients. The group with experience of a patient's suicide reported more suicide skills except for support and supervision. Finally, the participants who reported a patient's suicide presented a more conservative patient selection, difficulties in relationships, loss of self-esteem, dreams linked to suicide, intrusive thoughts of suicide, guilt, and anger. Our results show that knowledge of, and attitudes toward, suicide are essential in the management of suicide-risk patients.

RESUMO

The clinical importance of social cognition is well acknowledged in patients with psychosis, in particular those with first episode psychosis (FEP). Nevertheless, its brain substrates and circuitries remain elusive, lacking precise analysis between multimodal brain characteristics and behavioral sub-dimensions within social cognition. In the present study, we examined face processing of social cognition in 71 FEP patients and 77 healthy controls (HCs). We looked for a possible correlation between face processing and multimodal MRI characteristics such as resting-state functional connectivity (rsFC) and brain volume. We observed worse recognition accuracy, longer recognition response time, and longer memory response time in FEP patients when compared with HCs. Of these, memory response time was selectively correlated with specific rsFCs, which included the right subcallosal sub-region of BA24 in the ACC (scACC), only in FEP patients. The volume of this region was also correlated with memory response time in FEP patients. The scACC is functionally and structurally important in FEP-associated abnormalities of face processing measures in social cognition.
