Conspiracy mentality and health-related behaviour during the COVID-19 pandemic: a multiwave survey in Italy.

OBJECTIVES: This study aimed to (1) explore the changes in conspiracy mentality across the four waves of the COVID-19 pandemic; (2) assess the relationship between conspirative mentality and psychological/behavioural variables; (3) identify the predictors of conspirative mentality; and (4) explore the effect of conspirative mentality on COVID-19 protective behaviour. STUDY DESIGN: This was a multiwave survey. METHODS: A total of 10,013 Italian individuals, aged 18-70 years, were assessed across the four waves (from January to May 2021) through online survey. We collected information about the sociodemographic characteristics of participants, personal experiences of COVID-19 infection, trust, COVID-19 protective behaviours, COVID-19 risk perception, arousal, auto-efficacy, resilience and well-being. Conspiracy mentality was assessed with the Conspiracy Mentality Questionnaire. The statistical analyses included exploratory factorial analyses, Pearson correlations and multiple linear regressions. RESULTS: The conspiracy mentality score during the COVID-19 pandemic was medium-high (mean 59.0 on a 0-100 scale) and slightly increased from 58.2 to 59.9 across months, in parallel with a slight decrease in trust in health institutions and scientific informational sources. Individuals aged >35 years, poorly educated and particularly scared about their financial situation were at risk of showing higher levels of conspirative mentality. Higher levels of conspirative mentality were risk factors for low levels of COVID-19 protective behaviours. CONCLUSIONS: Clear and effective communication may improve trust in health institutions and informational sources, decrease conspirative theories and increase compliance with protective behaviour.

Clinical and Socio-demographic Variables Associated with the Outcome of Vocational Rehabilitation Programs: A Community-Based Italian Study.

This study aims to identify clinical and socio-demographic variables associated with the outcome of vocational rehabilitation programs (VRPs). All users of an Italian Community Mental Health Centre (CMHC) included in VRPs delivered according to the model of Supported Employment in years 2011-2016 were retrospectively enrolled. Fifty users who ended the program with employment were compared with fifty users who dropped out, with respect to clinical and socio-demographic variables. VRPs lasting less than 6 months and oriented toward the competitive labor market had a higher probability of employment. Among users who successfully ended the VRP, the median of health interventions significantly decreased after employment. In the same group of users, less non-health interventions strictly linked to the VRP were required, when compared with users who dropped out. We conclude that employment is associated with improvement of users' clinical conditions and reduced workload for the CMHC.

Long-Term Sheep Implantation of WIMAGINE®, a Wireless 64-Channel Electrocorticogram Recorder.

This article deals with the long-term preclinical validation of WIMAGINE® (Wireless Implantable Multi-channel Acquisition system for Generic Interface with Neurons), a 64-channel wireless implantable recorder that measures the electrical activity at the cortical surface (electrocorticography, ECoG). The WIMAGINE® implant was designed for chronic wireless neuronal signal acquisition, to be used e.g., as an intracranial Brain-Computer Interface (BCI) for severely motor-impaired patients. Due to the size and shape of WIMAGINE®, sheep appeared to be the best animal model on which to carry out long-term in vivo validation. The devices were implanted in two sheep for a follow-up period of 10 months, including idle state cortical recordings and Somato-Sensory Evoked Potential (SSEP) sessions. ECoG and SSEP demonstrated relatively stable behavior during the 10-month observation period. Information recorded from the SensoriMotor Cortex (SMC) showed an SSEP phase reversal, indicating the cortical site of the sensorimotor activity was retained after 10 months of contact. Based on weekly recordings of raw ECoG signals, the effective bandwidth was in the range of 230 Hz for both animals and remarkably stable over time, meaning preservation of the high frequency bands valuable for decoding of the brain activity using BCIs. The power spectral density (in dB/Hz), on a log scale, was of the order of 2.2, -4.5 and -18 for the frequency bands (10-40), (40-100), and (100-200) Hz, respectively. The outcome of this preclinical work is the first long-term in vivo validation of the WIMAGINE® implant, highlighting its ability to record the brain electrical activity through the dura mater and to send wireless digitized data to the external base station. Apart from local adhesion of the dura to the skull, the neurosurgeon did not face any difficulty in the implantation of the WIMAGINE® device and post-mortem analysis of the brain revealed no side effect related to the implantation. We also report on the reliability of the system; including the implantable device, the antennas module and the external base station.

Envenomation by Micrurus psyches in French Guiana.

We report here the first known envenomation by Micrurus psyches, the so-called Carib coral snake, which occurred on April 2016 in the surroundings of Saint-Laurent-du-Maroni, Western French Guiana. Besides local neurological symptoms, it featured unexpected electrocardiogram changes, which were emergence of a first-degree atrioventricular block and biphasic T waves, both transient. NewWorld elapid venoms were not known for being cardiotoxic so far. The possible reasons of this cardiac injury are discussed.

Feasibility of a psychoeducational family intervention for people with bipolar I disorder and their relatives: Results from an Italian real-world multicentre study.

BACKGROUND: Despite several guidelines recommend the use of psychoeducational family interventions (PFIs) as add-on in the treatment of patients with bipolar I disorder, their implementation on a large scale remains limited. The aim of the present study is to identify obstacles for the feasibility of PFIs in routine care. METHODS: This was a multicentre, real-world, controlled, outpatient trial, carried out in 11 randomly recruited Italian mental health centres. Two mental health professionals from each center attended a modular training course on PFI and provided the intervention. Difficulties and benefits experienced by mental health professionals in implementing the intervention were assessed through the Family Intervention Schedule (FIS-R), which was administered six times. RESULTS: Sixteen out of the 22 recruited professionals completed the training and administered the PFI to 70 patients with bipolar I disorder and their relatives. The retention rate of families receiving the intervention was 93%. Mental health professionals reported high levels of organizational difficulties, several benefits in their daily clinical work and low levels of intervention-related difficulties. The most important organizational obstacles were related to the need to integrate the intervention with other work responsibilities and to the lack of time to carry out the intervention. These difficulties did not decrease over time. Intervention-related difficulties were rated as less problematic since the first time assessment and tended to improve over time. LIMITATIONS: Low number of recruited professionals; use of a not previously validated assessment instrument. CONCLUSIONS: PFIs are feasible in routine care for the treatment of patients with bipolar I disorder and their relatives, and main obstacles are related to the organization/structure of mental health centres, and not to the characteristics of the intervention itself.

The design of the housing and the antenna have been optimized to ease the surgery and to take into account all the requirements of a clinical trial in particular patient safety and comfort. The main features of this WIMAGINE(®) implantable device and its architecture will be presented, as well as its performances and in vivo validations.

Adherence to antiretroviral therapy in children: a comparative evaluation of caregiver reports and physician judgement.

Adherence to antiretroviral (ART) therapy, as reported by children caregivers, was investigated and compared with physicians' estimates of adherence. Two parallel structured questionnaires were administered to caregivers of 129 HIV-infected children and to their physicians in seven different Italian reference centers. Doses omitted in the last four days were recorded. Perfect adherence (>95% of prescribed doses taken in the last four days before interview) was reported by caregivers of 103 (79%) children. Five children (5%) omitted one dose of any ART drug in four days and were considered adherent. Low (<95 but >80% of doses) and poor (<80% of doses) adherence were reported by 15 (12%) and six (5%) caregivers, respectively. Forty-eight children (37%) were judged to be non-adherent by their physicians, including 35 children who were receiving all the prescribed doses according to caregivers. The physicians identified eight out of the 21 non-adherent children as adherent. Non-adherence estimates by physicians closely correlated with poor clinical conditions. These data indicate that adherence is a major problem but there is a clear discrepancy between caregiver reports and physician judgement. The results underline the need of close surveillance of adherence in HIV-positive children in order to evaluate the effectiveness of ART therapy.

ISSQoL: a new questionnaire for evaluating the quality of life of people living with HIV in the HAART era.

OBJECTIVE: To design a Health-related Quality of Life (HRQoL) instrument for HIV-infected people in the era of highly active antiretroviral therapy (HAART). METHODS: The self-administered questionnaire was developed by an Italian network including researchers, physicians, people living with HIV, national institutions and community-based organizations (CBO) through several steps: (1) review of existing HRQoL literature and questionnaires for HIV-infected people; (2) selection of relevant domains measuring HRQoL in HIV-infected people, and identification of new domains related to new aspects of HRQoL concerning HAART-treated individuals; (3) conduction of two pre-test analyses in independent groups of Italian HIV-positive people (n approximately =100) distributed throughout the country. The objectives of the first pre-test were to verify the usefulness of the questionnaire, to construct a form easily understandable by everyone, to define the domains and their significance; the second pre-test aimed at evaluating and reshaping the questionnaire based on a statistical analysis of the outcomes of first pre-test; (4) validation analysis. A large cohort of people with HIV infection was recruited for the last step. RESULTS: The internal consistence reliability (Cronbach's alpha) was >or=0.70 for all domains. Most domains had Cronbach's coefficient >0.80. All domains demonstrated convergent and discriminant validity. The final version of ISSQoL includes two sections: HRQoL Core Evaluation Form (9 domains) and Additional Important Areas for HRQoL (6 domains). The ISSQoL was administered together with two additional forms: a Daily Impact of Symptoms Form and a Demographic Information Form. The Additional Important Areas for HRQoL include social support, interaction with medical staff, treatment impact, body changes, life planning, and motherhood/fatherhood. CONCLUSION: The data reported in the present paper provide preliminary evidence of the reliability and validity of the ISSQoL questionnaire for the measurement of HRQoL in HIV-infected people. The direct involvement of HIV-positive people in all the phases of the project was a key aspect of our work.

Knowledge and attitudes regarding preventative HIV vaccine clinical trials in Italy: results of a national survey.

We carried out a telephone survey to assess willingness to participate in HIV vaccine trials. The survey was conducted by interviewing randomly selected callers to the Italian National AIDS Help line. The questionnaire consisted of four sections: demographic information, knowledge about HIV vaccines and vaccines in general, factors related to participation in HIV vaccine trials, and acceptability of a future HIV vaccine. Over 50% of the sample had adequate knowledge about HIV and vaccines. Among the individuals interviewed, 37% would volunteer for a vaccine trial; those reporting high-risk behaviours were more likely to volunteer. Of the participants, 83% would agree to be vaccinated with a highly effective vaccine, and 92% would pay for the vaccine. Although the limits of telephone surveys should not be neglected, the results of this survey are encouraging.

Adherence to antiretroviral therapy and its determinants in children with human immunodeficiency virus infection: a multicentre, national study.

AIM: To investigate rates and determinants of adherence to antiretroviral therapy in Italian children infected with the human immunodeficiency virus (HIV). METHODS: An observational, cross-sectional multicentre study was performed through a structured interview with the caregivers of HIV-infected children. The interview included quantitative information on adherence in the 4 d before interview. Sociodemographic, clinical and psychosocial characteristics of children were recorded. RESULTS: 129 children (median age 96 mo) were enrolled, of whom 94 were on highly active antiretroviral therapy (HAART). Twenty-one (16%) omitted more than 5% of total doses in 4 d and were considered non-adherent. However, only 11% of caregivers reported that therapy had been administered at the correct times. No significant difference was found between age and the stage of HIV infection. Children aware of their HIV status were less adherent. Individual drugs showed a broad adherence pattern and children who received HAART were more adherent. Children receiving therapy from foster parents were more adherent than those receiving drugs from biological parents or relatives. CONCLUSIONS: Adherence is a major problem in children. Psychological rather than clinical or sociodemographic features and types of drug are major determinants of adherence.

Cognitive and affective disorders associated to HIV infection in the HAART era: findings from the NeuroICONA study. Cognitive impairment and depression in HIV/AIDS. The NeuroICONA study.

OBJECTIVE: To assess the natural story of HIV-associated affective and cognitive disorders and the relationship with clinical, pharmacological, immunological and behavioural factors. METHOD: A total of 395 HIV-positive patients, naive to Highly Active Antirectroviral therapy (HAART), with no severe psychiatric disorders have been enrolled in the Neuro-ICONA Study. All participants were administered a comprehensive data collection instrument including an addiction behaviour survey, a medical problem list, a psychiatric assessment, a validated neuropsychological test battery. RESULTS: The global prevalence of cognitive impairment and of prominent depressive symptomatology were 17.9 and 15.5%, respectively. A significant difference in the prevalence of prominent depressive symptomatology was observed between patients in HAART and those not taking HAART(14.1 vs. 23.8%; P = 0.05). CONCLUSION: Depressive and cognitive disorders affect a substantial proportion of HIV-seropositive subjects. The prevalence of prominent depressive symptomatology appears to significantly vary in relationship to the therapeutic protocol.

Quality of life assessment in HIV-positive persons: application and validation of the WHOQOL-HIV, Italian version.

QoL assessment is currently considered essential for clinical trials in HIV infection, as commonly used end-points (CD4 level, viral load, opportunistic diseases) are inadequate to catch the complexity of treatment outcomes. The World Health Organization has recently developed a standardized set of instruments to assess subjective quality of life (QoL) in different medical conditions, including HIV infection. Here we report evidence for the acceptability, reliability and validity of the Italian version of the WHOQOL-HIV. The Italian version of WHOQOL-HIV has been administered in a sample of 151 HIV-positive persons, consecutively attending the largest infectious diseases hospital in southern Italy. Mean time of administration and percentage of missing responses, Cronbach alpha, Pearson coefficient and oneway ANOVA were applied to assess, respectively, acceptability, reliability, convergent and disciminant validity, and sensitivity to change. Mean time of administration was 28 minutes; only 2 questionnaires showed more than 20% of missing responses. Cronbach alpha was above 0.70 in 22 of the 28 sections of the WHOQOL-HIV; it ranged between 0.53 and 0.68 in the remaining 6 sections. Each of the 7 QoL principal domains correlated with overall QoL at a significance level p < 0.001. Moreover, correlation between principal domains were always statistically significant (p < 0.01) with only two exceptions. Finally, mean scores in each QoL domain were in the expected direction (worse in AIDS patients as compared to asymptomatic and symptomatic persons). The Italian version of WHOQOL-HIV is a valid and reliable instrument to assess subjective QoL in HIV-positive persons. It seems potentially useful to assess patients' life satisfaction, and to calibrate standards of care in different stages of the infection.

Psychological consequences of the 1998 landslide in Sarno, Italy: a community study.

OBJECTIVE: This community study assessed the prevalence of post-traumatic stress disorder (PTSD) and the psychosocial consequences of the landslide which occurred in Sarno, Southern Italy, in May 1998. METHOD: A random sample (n=272) of the population living in the highest risk area of Sarno, and a control group recruited in a small town situated near the disaster area, but not affected by the event, were assessed 1 year after the disaster by standardized instruments. RESULTS: Of the subjects recruited in Sarno, 27.6% met DSM-IV criteria for PTSD; 59% subjects recruited in Sarno and 35% of the control group were identified as "probable cases" by the GHQ-30 (P<0.0001). Subjects recruited in Sarno had significantly higher scores on the four GHQ-30 subscales identified by factor analysis. CONCLUSION: This study emphasizes the negative impact of a natural catastrophic event on mental health, and the need for preventive interventions.

Has there been a decrease in the prevalence of mood disorders in HIV-seropositive individuals since the introduction of combination therapy?

PURPOSE: The aim of this study was to assess the prevalence of current mood disorders in HIV-seropositive patients treated with combined antiretroviral drug therapy including or not protease inhibitors. SUBJECTS AND METHODS: A random sample of 90 subjects consecutively attending, between February 1 and July 31, 1998, the outpatient unit of the Second Department of Infectious Diseases of the 'L. Sacco' Hospital in Milan was assessed by means of the Structured Clinical Interview for DSMIII-R (SCID) and the Zung Self-Rating Depression Scale (ZSDS). RESULTS: Twenty-three-point-three percent of the subjects were classified in CDC stage A, 32.3% in CDC stage B and 44.4% in CDC stage C. A DSMIII-R psychiatric diagnosis of current mood disorder was found in 4.4% of the recruited sample (dysthymia: 2.2%; adjustment disorder with depressed mood: 2.2%). CONCLUSIONS: Direct and indirect effect of new combination therapies, epidemiological changes in social groups affected by HIV and possible modifications in social perception of people with HIV infection may explain, at least in part, the decreased prevalence of current mood disorders observed in our study as compared to prevalence rates reported in the pre-HAART era.

[Medical decisions at the end of life: epidemiological and psychiatric aspects]. / Decisioni mediche di fine vita: aspetti epidemiologici e psichiatrici.

OBJECTIVE: Despite the ongoing moral and legal debate, there is still a paucity of empirical literature on the actual occurrence of Medical Decisions at the End of Life (MDEL). Moreover, the psychiatrist's role in this scenario is still unclear. METHODS: This paper systematically reviews currently available literature on euthanasia (EU) and physician assisted suicide (PAS). Published articles were selected if they reported either: 1) prevalence estimates of patients' requests of EU/PAS; and/or 2) prevalence estimates of physicians' actual EU/PAS practices. Papers exploring the issue of MDEL-related psychiatric consultation have been also included in the review. RESULTS: The empirical evidence reported in this paper shows that EU/PAS demands and acts are not uncommon in medical practice. A conservative estimate indicates that at least 10% of physicians have granted a request of EU/PAS. The involvement of consultation-liaison psychiatrists in MDELs seems to be relatively rare. CONCLUSIONS: Euthanasia and other MDELs require physicians' thoughtful evaluation of criteria guiding professional decision-making. To this purpose, epidemiological and psychosocial research can offer a valuable contribution.

HIV-associated dementia: clinical, epidemiological and resource utilization issues.

Among mental disorders associated with HIV infection, dementia is the one most likely to have a major impact on public health, both as a result of the high levels of individual disability, and the greater demand of health care resource utilization. Epidemiologic and economic impact of HIV-associated dementia needs to be estimated, in order to provide policy makers and health managers with the information required for decision making and resource allocation. An increase in HIV encephalopathy prevalence rates may be expected as a consequence of longer survival time in dementia patients and in patients with other AIDS defining disease (longer survival increases the risk of developing HIV encephalopathy). A resource utilization study shows that, in the chronic stage of the disease, in-patient days per person-year are almost double in AIDS subjects with neurological complications as compared with those without neurological complications; no major difference appears when considering out-patients consultations and day-care treatments. In conclusion, a significant rise in resource utilization and in related costs may be anticipated as a consequence of the increasing prevalence of HIV encephalopathy. Further studies seem necessary to compare different approaches in the management of this debilitating disease, in view of a more rational utilization and allocation of resources.
