Introduction
The closure of forensic psychiatric hospitals and the conversion to a residential model of care based on secure residential units in the community (REMS) has made Italy the first and ...only country in the world to have followed the principles of the deinstitutionalization movement. Following the reform, several management issues have emerged, such as the creation of long waiting lists for admission to REMS. Improper hospitalization in Acute Psychiatric Units (SPDC) has often been used to address this issue. In addition, the handover of inmates’ care to Mental Health Departments (DSMD’s) has posed further challenges. To date, the field has received little attention from international literature.
Objectives
Description and analysis of a sample of offender inpatients hospitalized in an acute psychiatric unit.
Methods
We conducted a retrospective study including male offenders admitted to the SPDC of San Gerardo Hospital (ASST Monza), between January 2007 and September 2022. Data analysis was performed by using SPSS.
Results
120 male offenders were included for a total of 204 admissions. 98 offenders (81.7%) were hospitalized once. We observed an absolute (N=1; N=30) and percentage (0.2%;12%) increase in the number of hospitalized offenders per year during the time period under study. Jail was the main provenance in the sample (46.6%), followed by residential care facilities (27%) and the psychiatric observation unit (ROP) of Monza’s jail (10.8%). The two most prevalent diagnoses were personality disorders (37.5%) and psychosis (39.2%). In addition, 66 subjects (55%) had a history of substance abuse. The average duration of hospitalization was 19.45 days; it increased to 77 days for inpatients waiting to be transferred to REMS. Hetero-aggressive behavior as the reason for admission was associated with longer hospitalization (p=0.031), while attempted suicide correlated to shorter hospital stay (p=0.032). Out of the 55 offenders who attempted suicide, 41 came from jail (74.5%). Finally, longer hospitalizations were associated with an increased number of adverse events (p=0.001).
Conclusions
Psychiatric hospitalizations of offenders have increased over the last years. This population tends to require longer hospital stays (regional average of SPDC hospitalization in Lombardy: 14 days), which are even lengthier for inpatients destined to REMS. Longer hospitalizations exert a large burden on DSMD’s and impact the general health of patients, exposing them to a higher risk of adverse events. Further studies are needed to confirm our findings and to develop better strategies for the management and care of offender patients.

The aim of the present study was to identify clinical and socio-demographic factors associated with duration of untreated illness (DUI) in patients affected by panic disorder (PD).
Data were ...collected from patients' medical records (N = 157) of two mental health services respectively located in Milan and in Monza (Italy). Correlation analyses and analysis of variance (ANOVAs) were run to analyse the relation between DUI and quantitative/qualitative variables respectively. Statistically significant variables in uni- variate analyses were then inserted in a linear multivariable regression model (backward procedure).
Mean DUI was 27.33 (±50.56) months. Patients with an earlier age at onset (r = -0.270; p < .01), a longer duration of illness (r = 0.483; p < .01) and who received a lifetime psychotherapy (F = 6.86; p = .01) had a longer DUI. The final global model showed that a longer DUI was associated with pre-onset poly-substance misuse (p = .05) and a longer duration of illness (p < .01).
The results of our study showed that a longer DUI was predicted by clinical factors such as the presence of a pre-onset poly-substance use disorder and that delayed proper treatment can lead to a chronicization of PD, as indicated by a longer duration of illness. Further studies are needed to in-depth investigate the role of DUI in influencing the course and outcome of anxiety disorders, including PD.
Social anxiety disorder (SAD) is a common psychiatric condition associated with a high risk of psychiatric comorbidity and impaired social/occupational functioning when not promptly treated. The ...identification of biological markers may facilitate the diagnostic process, leading to an early and proper treatment. Our aim was to systematically review the available literature about potential biomarkers for SAD. A search in the main online repositories (PubMed, ISI Web of Knowledge, PsychInfo, etc.) was performed. Of the 662 records screened, 61 were included. Results concerning cortisol, neuropeptides and inflammatory/immunological/neurotrophic markers remain inconsistent. Preliminary evidence emerged about the role of chromosome 16 and the endomannosidase gene, as well as of epigenetic factors, in increasing vulnerability to SAD. Neuroimaging findings revealed an altered connectivity of different cerebral areas in SAD patients and amygdala activation under social threat. Some parameters such as salivary alpha amylase levels, changes in antioxidant defenses, increased gaze avoidance and QT dispersion seem to be associated with SAD and may represent promising biomarkers of this condition. However, the preliminary positive correlations have been poorly replicated. Further studies on larger samples and investigating the same biomarkers are needed to identify more specific biological markers for SAD.
The evolutionary conservation of T lymphocyte subsets bearing T-cell receptors (TCRs) using invariant α-chains is indicative of unique functions. CD1d-restricted natural killer T (NK-T) cells that ...express an invariant Vα14 TCRα chain have been implicated in microbial and tumour responses, as well as in auto-immunity. Here we show that T cells that express the canonical hVα7.2-Jα33 or mVα19-Jα33 TCR rearrangement are preferentially located in the gut lamina propria of humans and mice, respectively, and are therefore genuine mucosal-associated invariant T (MAIT) cells. Selection and/or expansion of this population requires B lymphocytes, as MAIT cells are absent in B-cell-deficient patients and mice. In addition, we show that MAIT cells are selected and/or restricted by MR1, a monomorphic major histocompatibility complex class I-related molecule that is markedly conserved in diverse mammalian species. MAIT cells are not present in germ-free mice, indicating that commensal flora is required for their expansion in the gut lamina propria. This indicates that MAIT cells are probably involved in the host response at the site of pathogen entry, and may regulate intestinal B-cell activity.
L-glutamate, the major excitatory neurotransmitter, also has a role in non-neuronal tissues and modulates immune responses. Whether NMDA receptor (NMDAR) signalling is involved in T-cell development ...is unknown. In this study, we show that mouse thymocytes expressed an array of glutamate receptors, including NMDARs subunits. Sustained calcium (Ca(2+)) signals and caspase-3 activation in thymocytes were induced by interaction with antigen-pulsed dendritic cells (DCs) and were inhibited by NMDAR antagonists MK801 and memantine. NMDARs were transiently activated, triggered the sustained Ca(2+) signal and were corecruited with the PDZ-domain adaptor postsynaptic density (PSD)-95 to thymocyte-DC contact zones. Although T-cell receptor (TCR) activation was sufficient for relocalization of NMDAR and PSD-95 at the contact zone, NMDAR could be activated only in a synaptic context. In these T-DC contacts, thymocyte activation occurred in the absence of exogenous glutamate, indicating that DCs could be a physiological source of glutamate. DCs expressed glutamate, glutamate-specific vesicular glutamate transporters and were capable of fast glutamate release through a Ca(2+)-dependent mechanism. We suggest that glutamate released by DCs could elicit focal responses through NMDAR-signalling in T cells undergoing apoptosis. Thus, synapses between T and DCs could provide a functional platform for coupling TCR activation and NMDAR signalling, which might reflect on T-cell development and modulation of the immune response.
The measurement of precursor frequencies of donor anti-recipient cytotoxic T lymphocytes (CTL-p) has been shown to predict the incidence and the severity of acute graft-versus-host disease (aGVHD) in ...unrelated donor bone marrow transplantation (BMT). In HLA-identical sibling BMT, where aGVHD is most likely caused by minor histocompatibility antigen mismatches, this assay did not appear to be sensitive enough to provide similar predictive information. In this study, the CTL-p frequencies and the incidence and severity of aGVHD in 51 onco-hematological patients transplanted from HLA-identical siblings were compared. Sibling donors were selected on the basis of HLA identity using serological typing for HLA-A, B, C antigens, whereas HLA-DRB was tested by molecular analysis. Sibling identity was also confirmed by DNA heteroduplex analyses. Fifteen out of 21 (71%) patients with high precursor frequency (>1:100 x 10(3)) and 12 out of 30 (40%) with low precursor frequency (<1:100 x 10(3)) experienced clinically significant (II-IV) aGVHD. A significant correlation (P = 0.04) between CTL-p frequency and severe aGVHD was demonstrated. Moreover there was a positive trend for a high frequency response according to an increasing grade of aGVHD, which was statistically significant (P = 0.04). In our experience the CTL-p assay is a helpful predictive test for aGVHD in HLA-identical sibling BMT, indicating high risk patients possibly requiring additional prophylaxis.
