Gender differences in Anxious-depressive symptomatology, Metabolic Syndrome and Colorectal Adenomas among outpatients undergoing colonoscopy: a cross-sectional study according to a PNEI perspective.

BACKGROUND AND AIM OF THE WORK: To explore gender differences in patients suffering from anxious-depressive symptoms, Metabolic Syndrome (MetS) and Colorectal Adenomas (CRAs) in a sample of outpatients undergoing colonoscopy for screening purposes. METHODS: Cross-sectional study. 126 consecutive outpatients of both sexes undergoing colonoscopy for non-specific abdominal symptoms between January 2015 and June 2021 at the Modena Policlinico General Hospital (Modena, Northern Italy) were enrolled. MetS was diagnosed according to ATPIII and IDF criteria. Anxiety and depression were assessed with the Hospital Anxiety and Depression Scale (HADS), while the Temperament and Character Inventory (TCI) was used to study personality. The SF-36 was also included as a measure of quality of life perception. RESULTS: Among 126 outpatients (51.60% male) undergoing colonoscopy, 51 (44%) had CRAs, 54 (47%) MetS, 41 (41.40%) anxiety symptoms, 22 (22.20%) depressive symptoms and 13 (13.10%) combined anxious-depressive symptoms. HADS-Anxiety (t=2.68, p=0.01) and TCI Reward Dependence (TCI-RD) (t=3.01, p=0.00) mean scores were significantly higher in women; conversely, SF-36 Mental Component Summary scores were higher in men. CRAs were significantly prevalent in men (χ2=9.32, p=0.00) and were statistically significantly associated with male sex at the univariate logistic regression analysis (OR=3.27; p<0.01). At the multivariate logistic regression, diastolic hypertension (p<0.01) was positively associated with male sex, while TCI-RD (p=0.04) and HDL hypocholesterolemia (p=0.02) were inversely associated with male sex. CONCLUSIONS: Several significant gender differences in anxious-depressive symptoms, MetS and CRAs were found. These preliminary data suggest the need to consider gender specificities while implementing therapeutic, diagnostic, and preventive strategies.

Machine-Learning for Prescription Patterns: Random Forest in the Prediction of Dose and Number of Antipsychotics Prescribed to People with Schizophrenia.

Objective: We aimed to predict antipsychotic prescription patterns for people with schizophrenia using machine learning (ML) algorithms. Methods: In a cross-sectional design, a sample of community mental health service users (SUs; n = 368) with a primary diagnosis of schizophrenia was randomly selected. Socio-demographic and clinical features, including the number, total dose, and route of administration of the antipsychotic treatment were recorded. Information about the number and the length of psychiatric hospitalization was retrieved. Ordinary Least Square (OLS) regression and ML algorithms (i.e., random forest [RF], supported vector machine, K-nearest neighborhood, and Naïve Bayes) were used to estimate the predictors of total antipsychotic dosage and prescription of antipsychotic polytherapy (APP). Results: The strongest predictor of the total dose was APP. The number of Community Mental Health Centers (CMHC) contacts was the most important predictor of APP and, with APP omitted, of dosage. Treatment with anticholinergics predicted APP, emphasizing the strong correlation between APP and higher antipsychotic dose. RF performed better than OLS regression and the other ML algorithms in predicting both antipsychotic dose (root square mean error = 0.70, R2 = 0.31) and APP (area under the receiving operator curve = 0.66, true positive rate = 0.41, and true negative rate = 0.78). Conclusion: APP is associated with the prescription of higher total doses of antipsychotics. Frequent attenders at CMHCs, and SUs recently hospitalized are often treated with APP and higher doses of antipsychotics. Future prospective studies incorporating standardized clinical assessments for both psychopathological severity and treatment efficacy are needed to confirm these findings.

Factors associated with the transition of adolescent inpatients from an intensive residential ward to adult mental health services.

Transition of young people from Child and Adolescent Mental Health Services (CAMHS) to Adult Mental Health Services (AMHS) is a complex process. Transition rates are heterogeneously reported, with wide definitions and ranges. Few data are available regarding predictive factors of a successful transition. We explored factors associated with transition in a cohort of former inpatients of a Children and Adolescents Intensive Treatment Ward (CAITW). Socio-demographic and clinical features of patients previously admitted to CAITW were matched to AMHS data for those patients having reached age requirements. We built multiple logistic regression models to identify factors associated with transfer to AMHS (either inpatient or outpatient) and with successful retention in treatment (RIT) at six (short RIT), 12 (intermediate RIT) and 24 months after transfer (long RIT). From a cohort of 322 inpatients, 126 reached the age threshold for transfer to AMHS in the study period. The transfer rate was 50%. Two years after transition-age boundary, CAMHS-AMHS continuity of care was found in 40% and disengagement in 6% of cases. Longer and multiple hospitalizations, atypical antipsychotics prescription and a diagnosis of psychotic disorders were factors associated with short and intermediate RIT. A positive psychiatric family history was negatively associated with successful short and intermediate RIT. Diagnosis of psychosis and learning-supported school attendance were associated with long RIT. Young adults with a history of psychiatric inpatient admission as children or adolescents have a relatively high rate of transition to AMHS. A diagnosis of psychosis seems to be the strongest predictor for transition in these patients. Further research should focus on patients' schooling needs and on children of parents with mental health problems to enhance family and educational system engagement.

L'associazione tra fumo di tabacco e crisi economiche in Italia.

OBJECTIVES: to analyse the association between smoking behaviour and economic crises in Italy between 1993 and 2015. DESIGN: ecological study, carried out on data of the Italian National Institute of Statistics, by means of fixed-effect panel regressions. SETTING AND PARTICIPANTS: the rate of smoking prevalence (disaggregated by gender and age) and the unemployment rate (disaggregated by gender and referring to individuals aged 15 or more) were collected for each of the twenty Italian regions. Also, percentage fluctuations of the national real gross domestic product (GDP) were collected to identify the years of severe economic crisis. MAIN OUTCOME MEASURES: number of people who smoke per 100 people with the same features. RESULTS: among men, increased regional unemployment rate was associated with increased smoking behaviour only in the group aged 25-34 years. Differently, severe economic crises were associated with increased smoking in almost all age groups, except for men aged 15-24 years. A 1-point decrease in GDP was associated with 0.75 more smokers aged 15 years or more. The highest coefficient was reported among men aged 35-44 years, where a 1-point decrease in GDP was associated with 1.16 more smokers (every 100 men). This age group is also featured by the second highest prevalence of tobacco smoking (36.8%). Among women, a 1-point increase in the regional unemployment rate was associated with 0.08 less smokers every 100 women. Similarly, periods of severe economic crisis at national level were associated with reduced smoking behaviour among women aged 15 years or more, specifically those aged 15-24 years. Differently, women aged 25-34 and 65 years or more showed an association similar to that reported among men. In these groups, a 1-point decrease in GDP was associated with 0.67 and 1.08 more smokers every 100 women. While among the latter the prevalence of tobacco smoking is the lowest, among the former it is the third highest prevalence (21.69%). Therefore, increased smoking behaviour due to economic crises seems to occur especially among women aged 25-35 years old, as happens among men. CONCLUSIONS: men in almost all age groups and women aged 25-34 and 65 years or more represent vulnerable groups in which smoking behaviour may increase in times of economic hardship. Therefore, specific policies should be implemented to prevent this occurrence, as well as the negative health outcomes of tobacco smoking.

Impact of Antidepressant Prescriptions on Suicidal Behavior in Times of Severe Financial Strain.

ABSTRACT: This descriptive study observes the relationship between antidepressant prescriptions and the suicide rate in Italy in the 2000s to the mid-2010s, which includes a period of severe economic crisis. The observation period was from 2000 to 2015. Suicide and unemployment rates disaggregated by age and sex were collected from the Italian Institute of Statistics. Statistical analyses were performed using correlations between suicide rates and the defined daily dose, with reference to selective serotonin reuptake inhibitors (SSRIs), tricyclic antidepressants (TCAs), and other types of antidepressants. Fixed-effects panel regressions were also run. Increases in SSRIs prescriptions were associated with decreases in suicide rates among both men and women. However, when the analyses were adjusted for the rate of growth of the unemployment rate and for gross domestic product, the associations were weaker. The potential protective factor of SSRIs with respect to suicidal behavior may be reduced by severe recessions, especially when unemployment increases.

Sarcosine as an add-on treatment to antipsychotic medication for people with schizophrenia: a systematic review and meta-analysis of randomized controlled trials.

Background: N-methyl-glycine (sarcosine) may improve symptoms of schizophrenia via NMDA-receptor modulation. We undertook a systematic review and meta-analysis to determine the short- and long-term effectiveness of sarcosine for schizophrenia.Research design and methods: The databases Medline, Scopus, EMBASE, Cochrane Library, and PsycINFO were searched. We included six independent randomized controlled trials of sarcosine as add-on treatment to current antipsychotic medication, involving 234 adult participants with schizophrenia, and reporting data on symptom severity. Standardized mean differences (SMDs) were used to assess continuous outcomes.Results: In all of the trials, sarcosine was administered orally at 2 g/day. Treatment with sarcosine did not show a significant effect size at any of the pre-established time points (2, 4, 6, or >6 weeks), due to marked quantitative heterogeneity. However, sarcosine was associated with significant reductions of symptom severity in the subgroups of people with chronic schizophrenia and no treatment resistance (namely, without added-on clozapine) in relation to the SMD after 6 weeks treatment at -0.36 and -0.31, respectively.Conclusions: People with chronic and non-refractory schizophrenia may benefit from the use of sarcosine as an add-on treatment to antipsychotic medication. Due to the good tolerability of this compound, future trials with larger sample sizes appear worthwhile.

Translation and Validation of an Italian Language Version of the Religious Beliefs and Mental Illness Stigma Scale (I-RBMIS).

The aim of this study is to validate the Italian version of the Religious Beliefs and Mental Illness Stigma Scale (I-RBMIS): a self-report measure of religious beliefs that may contribute to stigma regarding mental disorders. Scale validation included: linguistic validation; pilot test for understandability; face validity; factor analysis as test of dimensionality; Kaiser-Meyer-Olkin test to evaluate sample sampling adequacy; internal consistency was assessed using Cronbach's alpha; scale validity was assessed through concurrent criterion validity using as gold standard the Italian version of Attribution Questionnaire 27 and mental health knowledge schedule; A total of 311 people agreed to participate in the study. Face validity showed that 13 items out of 16 were completely understandable while only three items (4, 9 and 13) highlighted small lexical concerns. The average compilation time was under 4 min. Bartlett's test for sphericity was statistically significant (Χ2 = 1497.54; df = 120; p < 0.001). Cronbach's alpha values were acceptable both for the entire questionnaire (0.80) and for the morality/sin subscale (0.73), whereas it was slightly below the standard cutoff for the spiritually oriented causes/treatments (0.68). Scale validity showed a positive correlation between I-RBMIS and AQ-27-I, and a negative correlation between I-RBMIS and MAKS-I. I-RBMIS demonstrated good psychometric properties to assess stigmatizing religious beliefs toward mental illness in general population.

Diagnostic Agreement between Physicians and a Consultation-Liaison Psychiatry Team at a General Hospital: An Exploratory Study across 20 Years of Referrals.

Consultation-liaison psychiatry (CLP) manages psychiatric care for patients admitted to a general hospital (GH) for somatic reasons. We evaluated patterns in psychiatric morbidity, reasons for referral and diagnostic concordance between referring doctors and CL psychiatrists. Referrals over the course of 20 years (2000-2019) made by the CLP Service at Modena GH (Italy) were retrospectively analyzed. Cohen's kappa statistics were used to estimate the agreement between the diagnoses made by CL psychiatrist and the diagnoses considered by the referring doctors. The analyses covered 18,888 referrals. The most common referral reason was suspicion of depression (n = 4937; 32.3%), followed by agitation (n = 1534; 10.0%). Psychiatric diagnoses were established for 13,883 (73.8%) referrals. Fair agreement was found for depressive disorders (kappa = 0.281) and for delirium (kappa = 0.342), which increased for anxiety comorbid depression (kappa = 0.305) and hyperkinetic delirium (kappa = 0.504). Moderate agreement was found for alcohol or substance abuse (kappa = 0.574). Referring doctors correctly recognized psychiatric conditions due to their exogenous etiology or clear clinical signs; in addition, the presence of positive symptoms (such as panic or agitation) increased diagnostic concordance. Close daily collaboration between CL psychiatrists and GH doctors lead to improvements in the ability to properly detect comorbid psychiatric conditions.

Anxiety, depression and personality traits in Italian medical students.

BACKGROUND: Anxiety and depressive symptoms are common worldwide and, according to the World Health Organization, their prevalence has increased in the last decades. Further, dysfunctional personality traits are frequently coupled with anxiety and depressive symptoms. The prevalence of these symptoms is particularly relevant in medical students. METHODS: This study assessed the prevalence of anxiety and depressive symptoms in Italian medical students from the University of Modena and Reggio Emilia, by using the Hospital Anxiety and Depression Scale (HADS). Personality traits were assessed as well by employing the Personality Inventory for DSM-5, Brief Form (PID-5-BF), to explore their association with anxiety and depressive symptoms. A self-administered questionnaire was sent by e-mail to all the 944 students and 459 (48.6%) were enrolled. Besides the HADS and the PID-5-BF, the questionnaire included items concerning everyday life activities such as sports and academic features such as the years of attendance and average marks. RESULTS: A high prevalence of anxiety (n=92; 20%), depression (n=32; 7%), and comorbid anxiety-depressive symptoms (n=218; 47%) was reported. Multiple binary logistic analysis showed increased levels of anxiety and depression to be associated with personality traits, namely detachment and negative affect, and use of cognitive enhancers. On the other hand, sports activities, social activities and distraction were related to lower levels of symptoms. CONCLUSIONS: Symptoms of depression and anxiety are common among Italian medical students and specific interventions should be implemented to target them.

[Collective trauma and experience of uncertainty: a comparison between the 2012 earthquake and the 2020 pandemic in Italy.] / Trauma collettivo ed esperienza di incertezza: un confronto tra il terremoto del 2012 e la pandemia del 2020 in Italia.

The situation of uncertainty several people faced in Italy due to the SARS-CoV-2 epidemic suggested this contribution concerning the potential outcomes in some safety areas of the primary needs of the individual: safety and security needs, love and belonging needs, esteem, and self-actualization. When uncertainty features one or more of them, the risk of health outcomes increases, specifically with respect to mental health. This contribution compares the experience of the severe earthquake that hit Emilia-Romagna region (North Italy) in May 2012 and the epidemic of CoViD-19 officially started in Italy in February 2020. Both experiences were lived by the authors, as citizens and mental health professionals. The considerations presented stemmed out from the clinical experience and are articulated around some key words: surprise, length, places, society, work, welfare, feelings, economics. Similarities and differences are presented, suggesting that new therapeutic devices are necessary, to hold and treat patients during this specific epidemic, as well as during future ones. Up to the moment we have just been able to chase the shadow, by integrating medieval systems (quarantine) and hyper-technological systems (i.e., the most advanced resuscitation techniques).

Is Consultation-Liaison Psychiatry 'Getting Old'? How Psychiatry Referrals in the General Hospital Have Changed over 20 Years.

There is an ever-growing awareness of the health-related special needs of older patients, and Consultation-Liaison Psychiatry Services (CLPS) are significantly involved in providing such age-friendly hospital care. CLPS perform psychiatric assessment for hospitalized patients with suspected medical-psychiatric comorbidity and support ward teams in a bio-psycho-social oriented care management. Changes in features of the population referred to a CLPS over a 20-year course were analysed and discussed, especially comparing older and younger referred subjects. Epidemiological and clinical data from all first psychiatric consultations carried out at the Modena (North of Italy) University Hospital CLPS in the period 2000-2019 (N = 19,278) were included; two groups of consultations were created according to the age of patients: OV65 (consultations for patients older than 64 years) and NONOV65 (all the rest of consultations). Consultations for OV65 were about 38.9% of the total assessments performed, with an average of approximately 375 per year, vs. the 589 performed for NOV65. The number of referrals for older patients significantly increased over the 20 years. The mean age and the male/female ratio of the sample changed significantly across the years in the whole sample as well as both among OV65 and NOV65. Urgent referrals were more frequent among NOV65 and the rate between urgent/non urgent referrals changed differently in the two subgroups. The analysis outlined recurring patterns that should guide future clinical, training and research activities.

Affective and Sexual Needs of Residents in Psychiatric Facilities: A Qualitative Approach.

BACKGROUND: The affective and sexual needs of psychiatric patients are often under-considered, although they contribute significantly to their general well-being. Such topics are critical for Residential Psychiatric Facilities Users (RPFUs), whose daily life is paced by therapeutic settings. The aim of this paper is to better understand how sexuality and affectivity are expressed by the RPFUs at the Mental Health Department of Modena, within psychiatric residential settings. METHODS: Adult RPFUs took part into two audio recorded focus groups. Digital transcripts were analyzed using MAXQDA software in order to perform qualitative narrative analysis, so as to develop a hierarchical code system a posteriori (derived from the data). RESULTS: Eleven participants (eight RPFUs and three investigators) attended the first focus group, and eight participants (5 RPFUs and 3 investigators) attended the second focus group. 175 interventions were analyzed and coded under seven thematic areas: (a) contraception and sexually transmitted disease prevention (N = 17); (b) affective needs (N = 11); (c) personal experiences (N = 61); (d) regulation of sexual relations (N = 18); (e) Mental Health Professionals' (MHPs) openness towards the topic (N = 17); (f) MHPs' responses to RPFUs' sexual behaviors (N = 33); and (g) RPFUs proposals (N = 18). The highlighted topics suggest that affective and sexual relations commonly occur within residential psychiatric facilities, even if mental health services often fail to recognize and address RPFUs' affective and sexual needs as well as to provide effective solutions to manage them. CONCLUSIONS: RPFUs expressed a request for support to fulfill their affective and sexual needs and dedicated spaces for sexual activities to relieve their discomfort, while MHPs highlighted a need for awareness, training, and shared problem-solving strategies.

Stigma on Mental Health among High School Students: Validation of the Italian Version of the Attribution Questionnaire-27 (AQ-27-I) in a High School Student Population.

The purpose of this study was to describe the psychometric characteristics of the AQ-27-I in a high school student population. Students aged between 17 and 20 years and attending the fourth and fifth year of a scientific high school in Milan were approached at the school and were asked to fill in an anonymous socio-demographic form and the AQ-27-I. Cronbach's alpha was used to estimate the instrument reliability and confirmatory factor analysis (CFA) was conducted and compared to the original English version factor structure. The AQ-27-I demonstrated acceptable internal consistency, with a Cronbach's alpha of 0.87 and only one subscale (Personal responsibility) with an alpha lower than 0.60. Fit indices were very positive for the Dangerousness Model supporting the factor structure and paths of the original version. The Personal Responsibility Model, on the other hand, showed some weakness, concerning the process dynamics of the model. The results obtained are similar with those from other studies carried out in Italy and other countries. The questionnaire can be used for the quantitative description of stereotypes, emotions and behaviors associated with stigma in mental health in high school student populations.

Functionalized Enzyme-Responsive Biomaterials to Model Tissue Stiffening in vitro.

The mechanical properties of the cellular microenvironment play a crucial role in modulating cell function, and many pathophysiological processes are accompanied by variations in extracellular matrix (ECM) stiffness. Lysyl oxidase (LOx) is one of the enzymes involved in several ECM-stiffening processes. Here, we engineered poly(ethylene glycol) (PEG)-based hydrogels with controlled mechanical properties in the range typical of soft tissues. These hydrogels were functionalized featuring free primary amines, which allows an additional chemical LOx-responsive behavior with increase in crosslinks and hydrogel elastic modulus, mimicking biological ECM-stiffening mechanisms. Hydrogels with elastic moduli in the range of 0.5-4 kPa were obtained after a first photopolymerization step. The increase in elastic modulus of the functionalized and enzyme-responsive hydrogels was also characterized after the second-step enzymatic reaction, recording an increase in hydrogel stiffness up to 0.5 kPa after incubation with LOx. Finally, hydrogel precursors containing HepG2 (bioinks) were used to form three-dimensional (3D) in vitro models to mimic hepatic tissue and test PEG-based hydrogel biocompatibility. Hepatic functional markers were measured up to 7 days of culture, suggesting further use of such 3D models to study cell mechanobiology and response to dynamic variation of hydrogels stiffness. The results show that the functionalized hydrogels presented in this work match the mechanical properties of soft tissues, allow dynamic variations of hydrogel stiffness, and can be used to mimic changes in the microenvironment properties of soft tissues typical of inflammation and pathological changes at early stages (e.g., fibrosis, cancer).

Engineering Gels with Time-Evolving Viscoelasticity.

From a mechanical point of view, a native extracellular matrix (ECM) is viscoelastic. It also possesses time-evolving or dynamic behaviour, since pathophysiological processes such as ageing alter their mechanical properties over time. On the other hand, biomaterial research on mechanobiology has focused mainly on the development of substrates with varying stiffness, with a few recent contributions on time- or space-dependent substrate mechanics. This work reports on a new method for engineering dynamic viscoelastic substrates, i.e., substrates in which viscoelastic parameters can change or evolve with time, providing a tool for investigating cell response to the mechanical microenvironment. In particular, a two-step (chemical and enzymatic) crosslinking strategy was implemented to modulate the viscoelastic properties of gelatin hydrogels. First, gels with different glutaraldehyde concentrations were developed to mimic a wide range of soft tissue viscoelastic behaviours. Then their mechanical behaviour was modulated over time using microbial transglutaminase. Typically, enzymatically induced mechanical alterations occurred within the first 24 h of reaction and then the characteristic time constant decreased although the elastic properties were maintained almost constant for up to seven days. Preliminary cell culture tests showed that cells adhered to the gels, and their viability was similar to that of controls. Thus, the strategy proposed in this work is suitable for studying cell response and adaptation to temporal variations of substrate mechanics during culture.

An Integrated In Vitro-In Silico Approach for Silver Nanoparticle Dosimetry in Cell Cultures.

Potential human and environmental hazards resulting from the exposure of living organisms to silver nanoparticles (Ag NPs) have been the subject of intensive discussion in the last decade. Despite the growing use of Ag NPs in biomedical applications, a quantification of the toxic effects as a function of the total silver mass reaching cells (namely, target cell dose) is still needed. To provide a more accurate dose-response analysis, we propose a novel integrated approach combining well-established computational and experimental methodologies. We first used a particokinetic model (ISD3) for providing experimental validation of computed Ag NP sedimentation in static-cuvette experiments. After validation, ISD3 was employed to predict the total mass of silver reaching human endothelial cells and hepatocytes cultured in 96 well plates. Cell viability measured after 24 h of culture was then related to this target cell dose. Our results show that the dose perceived by the cell monolayer after 24 h of exposure is around 85% lower than the administered nominal media concentration. Therefore, accurate dosimetry considering particle characteristics and experimental conditions (e.g., time, size and shape of wells) should be employed for better interpreting effects induced by the amount of silver reaching cells.

Preliminary results of a multidisciplinary Italian study adopting a Psycho-Neuro-Endocrine-Immunological (PNEI) approach to the study of colorectal adenomas.

Background and aim of the work Colorectal mucosal precancerous lesions, metabolic syndrome (MetS) and psychiatric disorders may share a common low-grade local and systemic inflammation. Aim is to report on preliminary data concerning a research adopting a psycho-neuro-endocrine-immune (PNEI) approach to study outpatients undergoing colonoscopy. Methods A sample of patients undergoing colonoscopy was cross-sectionally investigated. Data on colorectal adenomas, MetS, early atherosclerosis, anxious-depressive symptoms, personality traits, and inflammatory markers were statistically analyzed. Results Sixty-two patients were recruited (female 50%, mean age: 60.8±9.4 years). The prevalence of adenomas and MetS was respectively of 45.2% and 41.9%. Anxiety and depressive symptoms were detected in 16 (32.7%) and 9 (18.4%) subjects, respectively. The presence of adenomas positively correlated with male sex (p=0.01), age (p<0.01), IL-6 (p=0.03), hsCRP (p=0.04), and MetS (p=0.03); it was also associated with hsCRP concentration (aOR=3.81, p=0.03). Conclusions Proinflammatory atherogenic status, psychological traits, increased mucosal inflammation, and metabolic parameters may share a common a pathogenic mechanism, worth studying.
