RESUMEN
BACKGROUND: Despite the EU recommendations on mental health, involuntary admission has been under researched in Italy for a long time and the overall picture of involuntary admission still appears fragmentary. The aims of this study are to evaluate involuntary admission rates in the Piedmont Region (Italy) and to investigate clinical and service-related variables associated with involuntary admission. METHODS: This is a cross-sectional retrospective multicenter study involving all psychiatric inpatients units of the general hospitals of Piedmont Region. Data on hospitalizations during 2016 were collected by consulting hospital discharge registers. The analyses were performed on two samples: 6018 patients (data analysis was run on first hospitalization during the study period for those with multiple admissions) and 7881 inpatient episodes. The association between involuntary admission and socio-demographic and clinical characteristics was examined through t-test for continuous variables, and Pearson's Chi-square test for categorical variables. Multilevel modeling was applied in logistic regression models with two levels: for the first model center and participants and for the second model center and inpatient episodes. RESULTS: Of 6018 inpatients, 10.1% were admitted involuntarily at first hospitalization, while the overall compulsory treatment rate was slightly lower (9.1%) in the inpatient episodes sample (n = 7881). The involuntary admission rates ranged from 0.8 to 21% among study centers. Involuntary admissions were primarily associated with younger age, diagnosis of schizophrenia or substance use disorders, longer duration of hospital stay, mechanical restraint episodes, and fewer subsequent hospitalizations during the study period. CONCLUSIONS: The rate of involuntary admission in the Piedmont Region was lower than the mean rate across countries worldwide. There were noteworthy differences in rates of involuntary admission among psychiatric units, although no relationship was found with characteristics of the psychiatric wards or of the areas where hospitals are located.
RESUMEN
PURPOSE: The term orthorexia nervosa (ON) was coined to describe altered thoughts and behaviours related to healthy eating. The prevalence of ON was found to scale up to almost 90% among high-risk populations (ballet dancers, athletes, and health workers). ON seem to share psychopathological aspects with both Eating Disorders (ED) and Obsessive-Compulsive Disorder (OCD). The aim of the study was to analyse the frequency and intensity of ON symptoms among subjects diagnosed with OCD, hypothesising that they would be higher than in two control groups (subjects with anxiety-depressive disorders and general population). METHODS: We conducted a multi-centre, observational, controlled study. Subjects filled in a socio-demographic questionnaire including questions related to life-style and two psychometric instruments: ORTO-15, for ON symptoms, and OCI-R, for OCD symptoms. Post hoc analysis of the dataset was performed using the revised version of ORTO-15, the ORTO-R. RESULTS: In the final sample of 328 subjects, the overall prevalence of ORTO-15-ON was 59.5%, mean score 37.9 ± 4.2. The mean score at the ORTO-R was 16.6 ± 4.6. No statistically significant differences were found in the prevalence of ON or in the mean ORTO-15 score among OCD patients and the two control groups, and this was confirmed by the multiple regression analysis. At the ORTO-R re-scoring, OCD patients scored significantly lower than the two clinical subgroups (p = .0005) and a lower ORTO-R score was associated to positivity at the OCI-R, confirming the initial hypothesis of the study. CONCLUSIONS: ON symptoms do seem to be more prevalent among subjects suffering from OCD. The psychometric properties of tools available to calculate ON symptoms, namely ORTO-15 vs. ORTO-R, play a relevant role in explaining such finding. ORTO-R seems to be a valid alternative able to overcome such difficulties, though further studies are needed to confirm this.

BACKGROUND: Soil transmitted helminths (STHs) are among the world's neglected tropical diseases. Morbidity due to STHs is greatest in school-age children who typically have the highest burden of infection. In 2001, WHO passed a resolution for the use of large-scale mass drug administration (MDA) to deworm vulnerable children through school based programs. Though effective, there is concern that MDA might not be sustainable over extended periods. Additionally the current MDA strategy does not consider child malnutrition, a very common malady in resource limited countries. We report a pilot evaluation of an innovation that bundles school feeding and deworming. METHODS: We designed a maize (corn) flour fortified with grounded dried papaya (Carica papaya) seeds and used it to prepare porridge as per the usual school meal recipe Children from three primary schools from Nandi County in Kenya were randomized into three arms: One school received 300 ml papaya fortified porridge daily (papaya group), the second school received similar serving of plain porridge without the pawpaw ingredient (control group) and the third school received plain porridge and the conventional MDA approach of one time 400 mg dosage of albendazole (albendazole arm). Prior to the randomization, an initial baseline stool microscopy analysis was done to determine presence and intensity of intestinal worms. Core indicators of nutrition-height, weight and hemoglobin counts were also assessed. The children were monitored daily for two months and final stool sample analysis and clinical monitoring done at the end of the study. Baseline and follow-up data were analyzed and compared through SAS version 9.1 statistical package. RESULTS: A total of 326 children participated in the trial. The overall prevalence of Ascaris lumbricoides was 29.4% (96), Trichuris Trichura 5.2% (17) and hookworm 1 (0.3%). Papaya seed fortified porridge reduced the Ascaris lumbricoides egg count by 63.9% after the two month period (mean 209.7epg to 75.7 p < 0.002) as compared to the albendazole arm 78.8% (129.5 epg to 27.5, p value 0.006). The control group showed an increase in egg count (42.epg to 56.3) though it was not statistically significant. Hemoglobin counts in the papaya group increased from a mean of 2 g/dL (11.5 g/dL to 13.5 g/dL, p < 0.001), as compared to the albendazole arm that increased by 1 g/dL (12.8-13.9, p < 0.001). No significant change was observed in the placebo arm (13.2 to 13.1). Interestingly the papaya group showed a significant reduction of children with Tinea capitis (ringworms) (54.4 to 34%, p < 0.002) as compared to the albendazole arm that showed an increase in ringworm infestation though not statistically significant (39.7 to 64.7% p = 0.608). CONCLUSION: Papaya seed fortified porridge had a significant effect on reduction of Ascaris lumbricoides burden. It had a better nutritional outcome and effect on child fungal infections than albendazole. Its application as a routine school meal may aid current national school based nutrition and deworming programs in Africa. TRIAL REGISTRATION: This study was retrospectively registered at Clinicaltrials.gov Ref. NCT02725255 on 31st March 2016.

OBJECTIVE: To evaluate the outcome of vaginal intraepithelial neoplasia (VaIN) treatment with CO2 laser vaporization in terms of local recurrence and progression to vaginal carcinoma. Additionally, the authors investigated the predictive factors for first recurrence. MATERIALS AND METHODS: The medical records of all patients treated for VaIN with CO2 laser vaporization at Sant'Anna Hospital in Turin (1995-2012), were retrospectively reviewed. A univariate logistic model was applied to evaluate selected clinical features as predictive factors for recurrence. A multivariate logistic regression analysis was then carried out including significant risk factors after univariate analysis (p < 0.05). RESULTS: The analysis included 285 out of 302 patients. Seventy-one (25%) women relapsed; of these 24 VaIN 1 (22%), 37 VaIN 2 (27%), and ten VaIN 3 (26%). The median time to the first recurrence was 5.2 months (1.4-127.8) for VaIN 1, 6.6 months (1-85.2) for VaIN 2, and 3.6 months (1.2-62) for VaIN 3. Sixty-one out of 71 patients were retreated with CO2 laser vaporization. At the last follow-up visit, 273 (96%) women were free from VaIN. No patients progressed to vaginal carcinoma. The multivariate model showed a higher risk of VaIN recurrence in the case of previous hysterectomy (HR 3.3, 95% CI 1.7-6.3, p < 0.001) and concomitant H-SIL on the Pap smear (HR 1.9, 95% CI 1.2-3.1, p = 0.008). CONCLUSION: CO2 laser vaporization is an effective low impact treatment for VaIN. Despite this, VaIN recur, in particular in cases of previous hysterectomy and concomitant H-SIL on the Pap smear. An intensive follow-up is proposed for women with a high risk of VaIN relapse.

OBJECTIVE: Several studies have shown that vascular endothelial growth factor (VEGF) is implicated in different neuronal processes involved in major depressive disorder (MDD) and in the mechanisms of action of antidepressants. The aim of this study was to investigate whether VEGF serum levels before treatment might be associated with the antidepressant response. METHOD: Two groups of patients were enrolled. One was composed of 50 MDD patients receiving an antidepressant drug treatment. Illness severity was measured before the treatment (T0) and after 12 weeks (T1). The second group was composed of 67 treatment-resistant depressed (TRD) patients undergoing electroconvulsive therapy (ECT). Illness severity was assessed before the treatment (T0) and 1 month after the end of ECT (T1). Blood samples for VEGF measurements were collected for both groups at the baseline (T0). RESULTS: A significant correlation was observed between baseline VEGF serum levels and the percentage reduction in depressive symptomatology after ECT (P = 0.003). In particular, VEGF levels at baseline were significantly lower in patients showing no response to ECT at follow-up (P = 0.008). No correlation between T0 VEGF concentrations and drug treatment outcome was found. CONCLUSION: Our results suggest that VEGF plays a role in the mechanism of response to ECT.

Exposure to work stress is associated with an increased risk of cardiovascular diseases, but the pathophysiological events underlying this relationship are still unclear. This paper reviews the progress made to identify the biomarkers of the two neuroendocrine pathways (the hypothalamic-pituitary-adrenal and the sympathetic adrenal axis) underlying the relationship between work stress and health and what efforts can be taken to realize the full promise of these biomarkers. The main findings of this review suggest that there is not a clear relationship between psychosocial factors and biomarkers of the sympatho-adrenal and HPA axis activation. The missing or poor covariance of perceived workstress and neuroendocrine biomarkers is not surprising, given the complex interplay of neurobiological events linking perceived stress to adverse health effects.

The risk assessment in apiculture points out methodological problems due to discontinuities and variability of exposure. This study analyzes a comprehensive set of potential determinants influencing the biomechanical risks in apiarists using recognized technical standards to ensure the technical-scientific accuracy; it offers a simplified methodological toolkit to be used in the risk assessment process and provides a user-friendly computer application. The toolkit asks the beekeeper to specify, for each month, the total number of hours worked, specifying the distribution among different tasks. As a result, the application calculates the average index risk and the peak index risk. The evidence of the study indicates that there are activities in this occupational area with biomechanical risks that remain for some tasks, while reducing the exposure time.

Titanium and its alloys represent the gold standard for orthopaedic and dental prosthetic devices, because of their good mechanical properties and biocompatibility. Recent research has been focused on surface treatments designed to promote their rapid osteointegration also in case of poor bone quality. A new surface treatment has been investigated in this research work, in order to improve tissue integration of titanium based implants. The surface treatment is able to induce a bioactive behaviour, without the introduction of a coating, and preserving mechanical properties of Ti6Al4V substrates (fatigue resistance). The application of the proposed technique results in a complex surface topography, characterized by the combination of a micro-roughness and a nanotexture, which can be coupled with the conventional macro-roughness induced by blasting. Modified metallic surfaces are rich in hydroxyls groups: this feature is extremely important for inorganic bioactivity (in vitro and in vivo apatite precipitation) and also for further functionalization procedures (grafting of biomolecules). Modified Ti6Al4V induced hydroxyapatite precipitation after 15 days soaking in simulated body fluid (SBF). The process was optimised in order to not induce cracks or damages on the surface. The surface oxide layer presents high scratch resistance.

BACKGROUND: Cannabis is the most used recreational drug worldwide. Its use can increase the risk of developing psychotic disorders and exacerbate their course. However, the relationship between cannabis use and dissociative symptoms has been scarcely investigated. AIMS: To examine differences in psychotic and dissociative symptoms, and in functioning in first-episode psychotic patients (FEPp) using cannabis compared with those not using cannabis. METHODS: Between January 2014 and December 2019, seventy FEPp with cannabis use disorder (N = 35) and without it (N = 35) were recruited in psychiatric inpatient facilities in the Italian regions of Lazio and Piemonte. All subjects were assessed at FEP, after 4 and 8 months, using the Positive and Negative Syndrome Scale (PANSS), the Global Assessment of Functioning (GAF) scale and the Dissociative Experiences Scale - II (DES-II). Detailed information on the pattern of cannabis and other substance use were collected. RESULTS: FEP using cannabis showed higher levels of positive symptomatology, dissociative experiences and worse functioning than their non-user counterpart, despite a comparable antipsychotic treatment. At an eight-month prospective evaluation, FEP using cannabis still showed higher levels of positive symptomatology and dissociation. Moreover, global functioning worsened over time in FEPp using cannabis, whereas it improved those not using it. DISCUSSION: Our findings suggest that a greater degree of dissociation and positive symptoms at FEPp and their persistence over time may characterise cannabis-associated psychosis. Both these factors might explain the overall functioning worsening over time that we observed in the cannabis-user group compared to the functioning improvement in the non-user group.

Recent schistosomiasis control efforts in sub-Saharan Africa have focused nearly exclusively on treatment of humans with praziquantel. However, the extent to which wild mammals act as reservoirs for Schistosoma mansoni and therefore as sources of renewed transmission following control efforts is poorly understood. With the objective to study the role of small mammals as reservoir hosts, 480 animals belonging to 9 rodent and 1 insectivore species were examined for infection with schistosomes in Kisumu, in the Lake Victoria Basin, Kenya. Animals were collected from 2 sites: near the lakeshore and from Nyabera Marsh draining into the lake. A total of 6.0% of the animals captured, including 5 murid rodent species and 1 species of shrew (Crocidura olivieri) were infected with schistosomes. Four schistosome species were recovered and identified using cox1 DNA barcoding: S. mansoni, S. bovis, S. rodhaini and S. kisumuensis, the latter of which was recently described from Nyabera Marsh. Schistosoma mansoni and S. rodhaini were found infecting the same host individual (Lophuromys flavopunctatus), suggesting that this host species could be responsible for the production of hybrid schistosomes found in the area. Although the prevalence of S. mansoni infection in these reservoir populations was low (1.5%), given their potentially vast population size, their impact on transmission needs further study. Reservoir hosts could perpetuate snail infections and favour renewed transmission to humans once control programmes have ceased.

BACKGROUND: The topics of stress and well-being in call centres are the focus of many different disciplines. This article presents the definition and start-up phases of the "Well-being in Telecom Italia Call Centres" project, which was coordinated and supervised by an interdisciplinary scientific committee composed of members from different universities. To address the topic of individual well-being in the organizational context means considering all the main factors that can affect wellbeing. OBJECTIVES: For this reason, the study assessed the topic from three different view-points (psychological/sociological/cultural, physical/chemical/biological, organizational/technological/work-related) in order to obtain an accurate as possible picture of the complex well-being dynamics. METHODS: The study plan shows that merging qualitative methods (interviews, observations, focus-groups) and quantitative methods (questionnaires, physiological response to perceived stress) was a central concern for the research team. RESULTS: The collected data highlighted important differences between psychological and physical well-being and discomfort according to the different kinds of call centre, the respondents'gender and working hours. CONCLUSIONS: This method enabled us to define the specific features of call centre environments, leading to a definition of work in the centres as an activity with high psychological uncertainty, where rigid rules coexist with demands of high levels of flexibility and competence, and suggesting the importance of specific organizational measures in order to improve well-being.

OBJECTIVES: To develop and assess a microsatellite technique to characterize populations of Schistosoma mansoni from humans. METHODS: For each of five patients, we calculated the allele count and frequency at 11 loci for several pools of miracidia (50 and 100), and compared these to population values, determined by amplifying microsatellites from 186 to 200 individual miracidia per patient. RESULTS: We were able to detect up to 94.5% of alleles in pools. Allele count and frequency strongly and significantly correlated between singles and pools; marginally significant differences (P < 0.05) were detected for one patient (pools of 50) for allele frequencies and for two patients (pools of 100) for allele counts. Kato-Katz egg counts and number of alleles per pool did not co-vary, indicating that further direct comparisons of the results from these two techniques are needed. CONCLUSIONS: Allele counts and frequency profiles from pooling provide important information about infection intensity and complexity, beyond that obtained from traditional methods. Although we are not advocating use of pooling to replace individual genotyping studies, it can potentially be useful in certain applications as a rapid and cost effective screening method for studies of S. mansoni population genetics, or as a more informative way to quantify and characterize human worm populations.

Schistosoma kisumuensis n. sp. is described based on 6 adult males and 2 adult females collected from the circulatory system of 3 murid rodent species, Pelomys isseli, Mastomys natalensis, and Dasymys incomtus. Specimens were collected from a single location, Nyabera Swamp, in Kisumu, Kenya in the Lake Victoria Basin. This new species is morphologically similar to members of the S. haematobium group, currently represented by 8 species parasitizing artiodactyls and primates, including humans. Schistosoma kisumuensis differs from these species by producing relatively small Schistosoma intercalatum-like eggs (135.2 x 52.9 microm) with a relatively small length to width ratio (2.55). Comparison of approximately 3000-base-pair sequences of nuclear rDNA (partial 28S) and mtDNA (partial cox1, nad6, 12S) strongly supports the status of S. kisumuensis as a new species and as a sister species of S. intercalatum. The cox1 genetic distance between these two species (6.3%) is comparable to other pairwise comparisons within the S. haematobium group. Separation of the Congo River and Lake Victoria drainage basins is discussed as a possible factor favoring the origin of this species.

BACKGROUND: In the last five years, the debate around the comorbidity between bipolar disorder (BD) and obsessive-compulsive disorder (OCD) has flourished within the international psychiatric community and several studies have been published on therapeutic strategies. METHODS: An update of our previous systematic review was conducted on clinical management of comorbid BD-OCD patients. Relevant papers published from July 1st 2013 to September 30th 2018 were identified searching the electronic databases MEDLINE, Embase, PsycINFO and the Cochrane Library. RESULTS: Fifteen studies were included. In all selected studies BD-OCD patients received mood stabilizers, alone or with second-generation antipsychotics (SGAs). Aripiprazole augmentation demonstrated to be effective as maintenance therapy and for treating obsessive-compulsive symptoms during manic episodes (40% of the studies, 6/15). Addition of antidepressants to mood stabilizers led to clinical remission of both conditions in only one case report. LIMITATIONS: Almost 50% of the selected studies are case reports. Enrolment of subjects mainly from outpatient specialty units might have introduced selection bias and limited community-wide generalizability. CONCLUSIONS: Mood stabilization should be the primary goal in treating BD-OCD patients. Aripiprazole augmentation to lithium carbonate seemed to be the best option in treatment-resistance comorbid patients. Addition of SRIs may be needed only in a minority of BD patients with refractory OCD.

OBJECTIVES: To identify the variables that are associated with persistence to Aripiprazole-Long Acting (A-LAI), in adult patients with schizophrenia. METHODS: Observational, retrospective, non-interventional study involving 261 patients with schizophrenia. RESULTS: Eighty-six percent of study subjects were persistent for at least 6 months. All subjects with baseline CGI-S of 1 or 2, 95% of subjects with CGI-S of 3, 86% with CGI-S of 4, 82% of subjects with CGI-S of 5, 73% of subjects with CGI of 6 and 90% of subjects with CGI of 7 were persistent. A-LAI treatment continuation rate was higher in patients with: 1) baseline CGI scoreâ¯≤â¯4; 2) schizophrenia dimension (LDPS) mania scoreâ¯≤â¯5; 3) psychotic spectrum schizoid scoreâ¯≤â¯11. CONCLUSIONS: A relatively high number of patients (nâ¯=â¯225, 86%) were persistent to A-LAI for at least 6 months. Not surprisingly, very severe patients were more unlikely to be persistent. However, it is noteworthy that a large number of subjects with high CGI score at the time when A-LAI was started (82% of subjects with CGI-S of 5, 73% of subjects with CGI of 6 and 90% of subjects with CGI of 7) were persistent. Larger, controlled, prospective and longer studies are warranted.

BACKGROUND: Affective temperaments have been shown to impact on the clinical manifestations and the course of bipolar disorder. We investigated their influence on clinical features and functional outcome of manic episode. METHOD: In a naturalistic, multicenter, national study, a sample of 194 BD I patients that initated or changed pharmacological treatment for DSM-IV-TR manic episode underwent a comprehensive evaluation including briefTEMPS-M, CTQ, YMRS, MADRS, FAST, and CGI-BP. Factorial, correlation and comparative analyses were conducted on different temperamental subtypes. RESULTS: Depressive, cyclothymic, irritable and anxious temperaments resulted significantly correlated with each other. On the contrary, hyperthymic temperament scores were not correlated with the other temperamental dimensions. The factorial analysis of the briefTEMPS-M sub-scales total scores allowed the extraction of two factors: the Cyclothymic-Depressive-Anxious (Cyclo-Dep-Anx) and the Hyperthymic. At final evaluation Dominant Cyclo-Dep-Anx patients reported higer scores in MADRS and in CTQ emotional neglect and abuse subscale scores than Dominant Hyperthymic patients. The latter showed a greater functional outcome than Cyclo-Dep-Anx patients. CONCLUSIONS: Affective temperaments seem to influence the course of mania. Childhood emotional abuse and neglect were related to the cyclothymic disposition. Cyclothymic subjects showed more residual depressive symptoms and Hyperthymic temperament is associated with a better short-term functional outcome.

The psychophysiological mechanism behind the development of stress-related diseases includes a long-term both increase and decrease in circulating cortisol levels, leading to an allostatic disregulation of the hypothalamic-pituitary-adrenal (HPA) axis. This research explores the relationship between perceived stress (assessed by means of the Job Strain Model) and neuroendocrine response quantified by means of repeated measures of salivary cortisol in 46 call-centre operators. Job strain influenced the total amount of cortisol response to waking, but not the cortisol excretion in the remainder of the day. The cortisol response to waking showed gender-specific differences, women excreting greater cortisol than men [AUC(t): coeff (IC 95%) = 16.2 (5.3-27.1); AUC(i): coeff (IC 95%) = 8.3 (2.4-14.2); MnInc: coeff (IC 95%) = 5.2 (1.6-8.9)]. In long run the gender-specific differences of the dis-regulation of the hypothalamic -pituitary-adrenal (HPA) axis can be related to differences on prevalence of autoimmune diseases.

There is a growing interest in the debate on nanoparticle safety for topical use. The benefits of nanoparticles have been shown in several scientific fields, but little is known about their potential to penetrate the skin lies. This study aims at evaluating in vitro silver nanoparticles skin penetration. Experiments were performed using the Franz diffusion cell method with intact and damaged human skin. Physiological solution was used as receiving phase and 70 microg/cm2 of silver nanoparticles dispersed in synthetic sweat were applied as donor phase to the outer surface of the skin for 24h. The receptor fluid measurements were performed by Electro Thermal Atomic Absorption Spectroscopy (ETAAS). Silver concentration of 0.2 microg/L was found in the receiving solutions of two cells, in which damaged skin membranes were set up. In the other tests, we obtained a silver concentration below the limit of detection in the receiving cells. Our experimental data show that silver nanoparticles permeation through intact and damaged skin is negligible. These findings are consistent with previously published results. Further researches are necessary to explore skin absorption of silver nanoparticles.
