This paper compares the texture of palygorskite after acid leaching with that of the product after extraction silica is removed. These effects were evaluated on the basis of nitrogen adsorption-desorption and mercury penetration porosimetry. Acid leaching at reflux temperature with 2 N HCl resulted in an increase in surface area from 138 to 399 m2/g, due to a partial (~50%) dissolution of the octahedral sheet and the creation of microporosity. This microporosity disappeared if the silica generated by the leaching was removed. The surface area also decreased from 399 to 214 m2/g, and the pore volume decreased from 0.538 to 0.507 cm3/g. The microporosity must therefore have been due to texture development in the generated silica.

Healthcare workers (HCWs) were at increased risk for mental health problems during the COVID-19 pandemic, with prior data suggesting women may be particularly vulnerable. Our global mental health study aimed to examine factors associated with gender differences in psychological distress and depressive symptoms among HCWs during COVID-19. Across 22 countries in South America, Europe, Asia and Africa, 32,410 HCWs participated in the COVID-19 HEalth caRe wOrkErS (HEROES) study between March 2020 and February 2021. They completed the General Health Questionnaire-12, the Patient Health Questionnaire-9 and questions about pandemic-relevant exposures. Consistently across countries, women reported elevated mental health problems compared to men. Women also reported increased COVID-19-relevant stressors, including insufficient personal protective equipment and less support from colleagues, while men reported increased contact with COVID-19 patients. At the country level, HCWs in countries with higher gender inequality reported less mental health problems. Higher COVID-19 mortality rates were associated with increased psychological distress merely among women. Our findings suggest that among HCWs, women may have been disproportionately exposed to COVID-19-relevant stressors at the individual and country level. This highlights the importance of considering gender in emergency response efforts to safeguard women’s well-being and ensure healthcare system preparedness during future public health crises.

Objective:
The accurate assessment of instrumental activities of daily living (iADL) is essential for those with known or suspected Alzheimer's disease or related disorders (ADRD). This information guides diagnosis, staging, and treatment planning, and serves as a critical patient-centered outcome. Despite its importance, many iADL measures used in ADRD research and practice have not been sufficiently updated in the last 40-50 years to reflect how technology has changed daily life. For example, digital technologies are routinely used by many older adults and those with ADRD to perform iADLs (e.g., online financial management, using smartphone reminders for medications.) The purpose of the current study was to a) asses the applicability of technology-related iADL items in a clinical sample; b) evaluate whether technology-based iADLs are more difficult for those living with ADRD than their traditional counterparts; and c) test if adding technology-based iADL items changes the sensitivity and specificity of iADL measures to ADRD.
Participants and Methods:135 clinically referred older adults (mean age 75.5 years) undergoing neuropsychological evaluation at a comprehensive multidisciplinary memory clinic were included in this study [37% with mild cognitive impairment (MCI) and 51.5% with dementia]. Collateral informants completed the Functional Activities Questionnaire (FAQ; Pfeffer, 1982) as well as 11 items created to parallel the FAQ wording that assessed technology-related iADLs such as digital financial management (i.e. online bill pay), everyday technology skills (i.e. using a smartphone; remembering a password), and other technology mediated activities (i.e. visiting internet sites; online shopping).
Results:Care partners rated tech iADLs items as applicable for the majority of items. For example, technology skill items were applicable to 90.4% of the sample and online financial management questions were applicable for 76.4% of participants. Applicability ratings were similar across patients in their 60's and 70's, and lower in those over age 80. Care partners indicated less overall impairment on technology-related iADLs (M =1.22, SD =.88) than traditional FAQ iADLs (M =1.36, SD = .86), t(129) = 3.529, p =.001). A composite of original FAQ paperwork and bill pay items (M = 1.62, SD = 1.1) was rated as more impaired than digital financial management tasks (M = 1.30, SD = 1.09), t(122) = 4.77, p <.001). In terms of diagnostic accuracy, tech iADL items (AUC= .815, 95% CI [.731, -.890]) appeared to perform comparably to slightly better than the traditional FAQ (AUC =.788, 95% CI [.705, .874]) at separating MCI and dementia, though the difference between the two was not statistically significant in this small pilot sample.
Conclusions:Technology is rapidly changing how older adults and those with ADRD perform a host of iADLs. This pilot study suggests broad applicability of tech iADL to the lives of those with ADRD and highlights how measurement of these skills may help identify trends in iADL habits that may help to mitigate the impact of ADRD on daily functions. Further, this data suggests the need to refine and improve upon existing iADL measures to validly capture the evolving technological landscape of those living with ADRD.

Introduction
There are no conclusive findings about the possible protective role of religion on students’ mental health during the COVID-19 pandemic. Therefore, more research is needed.
ObjectivesThe purpose of this study was to assess the relationship between the level of emotional distress and religiosity among students from 7 different countries during the COVID-19 pandemic.
MethodsData were collected by an online cross-sectional survey that was distributed amongst Polish (N = 1196), Bengali (N = 1537), Indian (N = 483), Mexican (N = 231), Egyptian (N = 565), Philippine (N = 2062), and Pakistani (N = 506) students (N = 6642) from 12th April to 1st June 2021. The respondents were asked several questions regarding their religiosity which was measured by The Duke University Religion Index (DUREL), the emotional distress was measured by the Depression, Anxiety, and Stress Scale-21 (DASS-21).
ResultsEgypt with Islam as the dominant religion showed the greatest temple attendance (organizational religious activity: M=5.27±1.36) and spirituality (intrinsic religiosity: M=5.27±1.36), p<0.0001. On another hand, Egyptian students had the lowest emotional distress measured in all categories DASS-21 (depression: M=4.87±10.17, anxiety: M=4.78±10.13, stress: M=20.76±11.46). Two countries with the dominant Christian religion achieved the highest score for private religious activities (non-organizational religious activity; Mexico: M=3.94±0.94, Poland: M=3.63±1.20; p<0.0001) and experienced a moderate level of depressive symptoms, anxiety, and stress. Students from Mexico presented the lowest attendance to church (M=2.46±1,39) and spirituality (M=6.68± 3.41) and had the second highest level of depressive symptoms (M=19.13±13.03) and stress (M=20.27±1.98). Philippines students had the highest DASS-21 score (depression: M=22.77±12.58, anxiety: M=16.07±10.77, stress: M=4.87±10.08) and their level of religiosity reached average values in the whole group. The performed regression analysis confirmed the importance of the 3 dimensions (organizational religious activity, non-organizational religious activity, intrinsic religiosity) of religiosity for the well-being of students, except for the relationship between anxiety and private religious activities. The result was as presented for depression: R2=0.0398, F(3.664)=91.764, p<0.0001, SE of E: 12.88; anxiety: R2=0.0124, F(3.664)=27.683, p<0.0001, SE of E: 10,62; stress: R2= 0.0350, F(3.664)=80.363, p<0.0001, SE of E: 12.30.
ConclusionsThe higher commitment to organizational religious activity, non-organizational religious activity, and intrinsic religiositywas correlated with the lower level of depressive symptoms, stress, and anxiety among students during the COVID-19 pandemic, but taking into account factors related to religiosity explains the level of emotional well-being to a small extent.

Introduction
Psychotic disorders carry several economical, psychological and social consequences, both at individual and community levels. Early intervention programs after first-episode psychosis which combine pharmacological and psychosocial strategies are aimed at reducing symptoms, lowering costs in the use of health and non-health care resources and improving overall functioning. AGES-Mind study is based on manualized psychotherapeutic interventions for people with first-psychosis episodes.
ObjectivesThe aim of the study was to evaluate the effect of a group psychotherapeutic intervention on the clinical status and use of clinical resources in a sample of patients with first-episode psychosis at 12 and 24 months after the beginning of the intervention. This cohort will be compared to patients with first-psychosis episodes without group psychotherapeutic intervention.
MethodsLongitudinal, observational, retrospective study on a cohort of N=46 patients with first-episode psychosis within the last 5 years. Two groups of 23 patients each were formed. The participants of one of those groups received group psychotherapy in the context of the AGES-Mind study and the other group received treatment as usual without group intervention. Non-exposed patients were matched by age, gender and time elapsed since first-episode psychosis with those exposed to the intervention. Sociodemographic data, clinical status and use of clinical resources outcome variables were assessed.
ResultsNo significant differences were found in clinical status and use of resources between participants and non-participants in the psychotherapeutic group intervention after 12 and 24 months.
ConclusionsAfter controlling for potentially confounding variables as sociodemographic, age and time since first-episode, participating in a group psychotherapeutic program does not seem to improve clinical variables or use of resources. Further studies with larger samples would be necessary to explore other variables, such as symptoms, satisfaction with the intervention or social functioning.

Introduction
Early intervention on a first psychotic episode is fundamental for a more favorable prognosis, and it usually combines pharmacological treatment, which mainly affects positive psychotic symptoms, with interventions that can improve the rest of the symptoms and associated problems such as deterioration in social functioning (Harvey & Penn, 2010; Fusar-Poli, McGorry & Kane, 2017). While Mindfulness is gaining more and more prominence in the field of psychotherapy (Chan et al., 2019; Cillesen et al., 2019), social cognition and social functioning are being researched as key targets on which to intervene after a first psychotic episode (Green, Horan & Lee, 2015).
SocialMIND® is a mindfulness-based social cognition training tailor-made to improve social functioning in people who have suffered a first psychotic episode within the last five years. It is currently being compared with a group Psychoeducational Multicomponent Intervention (PMI) in a Randomized Controlled Trial (RCT) (Mediavilla et al., 2019). Both group psychotherapies include 17 sessions delivered over a 9 month period: 8 weekly sessions, 4 biweekly sessions and 5 monthly sessions.
The results of SocialMIND® at 8 weeks showed improvements in social cognition and social functioning, specifically on affective social cognition and self-care (Mediavilla et al., 2021).
ObjectivesTo evaluate the efficacy of SocialMIND® in improving social functioning, measured by the Personal and Social Functioning (PSP) scale 16 weeks after starting the intervention, in people who have suffered a first psychotic episode in the last 5 years.
MethodsRandomized, controlled pilot trial (use of a psychoeducational multicomponent intervention or PMI as active comparator) of two parallel groups (SocialMIND® and PMI) with a 1:1 ratio using a blind evaluator.
ResultsNo statistically significant differences were found in the social functioning variable between the two treatment arms. Intragroup differences are observed in other secondary variables studied (social cognition) 16 weeks after starting the interventions.
ConclusionsSocialMIND® has not been shown to be more effective than a PMI in improving social functioning at 16 weeks after starting the intervention in people who have suffered a first psychotic episode in the five years prior to being included in the study.

Introduction
In the last decade, the prevalence of THC use is increasing among adolescents and adults. There is also strong evidence to suggest that cannabis use is associated with psychiatric comorbidities. The strongest evidence is found between cannabis use and psychotic disorder. However, the literature shows that those who have used cannabis in the past or for a large part of their lives are at higher risk of mood disorders, anxiety, personality disorder or other drug use than those who do not use cannabis in a harmful way.
ObjectivesTo provide an overview of the association between cannabis use and the different mental pathologies presented by the patients admitted during the study period. To describe the prevalence of THC use in the study according to the mental pathology presented by the patient.
MethodsA retrospective observational descriptive study was developed for 3 months, of all patients admitted to the acute unit of the psychiatric hospital. No exclusion criteria were included.
ResultsDuring the period of study 172 patients were admitted to the hospital, classified according to the main diagnosis we have: 49 patients suffer from schizophrenia, 26 bipolar affective disorder, 20 with depressive disorder, 20 with personality disorder, 19 with substance use disorder, 18 with other unspecified disorders and 20 patients with no known previous diagnosis. The prevalence of THC use in the study sample according to diagnosis, would be schizophrenia 16%, Bipolar affective disorder 19%, Depressive disorder 5%, Personality disorder 45%, Substance use disorder 21%, Unspecified disorders 11% and patients with no known previous diagnosis 10%.
ConclusionsThe results obtained in the study in terms of THC use are in agreement with those obtained in the literature. In our study, we observed that cannabis use is associated with psychotic disorders as well as with mood, personality and substance abuse disorders. Given that the frequency of use has increased and there is a strong association with different comorbid psychiatric diagnoses, guidance on modifications in medication strategies might be necessary.

Introduction
Patients with mental disorders frequently become non-adherent during their long term prescribed treatment. This situation frequently triggers clinical worsening and hospital admission. Therefore, non-adherence may result in poorer long term clinical outcomes and has economic implications for health-care providers (Carlos De las Cuevas et al. Neuropsychopharmacol Hung 2021; 23(4):347-362).
Objectives- To describe the adherence to oral and long acting injectable treatment in the sample of patients that were admitted to the short stay hospital unit during the period of study.
- To describe the adherence to treatment amongst psychiatric diagnosis in the sample of study.
MethodsIt was a retrospective observational study with a duration of three months. Data was collected from all patients admitted to the short stay hospital unit during the period of study and there were no specific exclusion criteria. Descriptive statistics were performed. To assess the adherence to pharmachological treatment the patient report, the family report and the pharmacy dispensation according to the existent informatic prescription platform was considered. Regarding the long acting injectable treatment the formulary of administration in the clinical history was checked.
ResultsDuring the period of study 172 patients were admitted to the short stay hospital unit. Of those, 146 patients had a previous pharmacologic prescription. Data of treatment was not possible to obtain in 7 patients. In the sample of study, 83.5% were on oral and 16.5% on long acting injectable treatment. The general adherence to treatment in the sample was 61.87%. In the oral treatment group the adherence was 58.4% and in the long acting injectable treatment group was 65.2%.
Amongst the different psychiatric diagnoses the outcomes of adherence to treatment were: 60.4% in schizophrenia and related psychosis, 62.5% in bipolar disorder, 78.6% in depression, 58.3% in personality disorders and 62% in addictive disorders.
ConclusionsIn our descriptive study adherence to treatment was higher in the long acting injectable treatment group, agreeing with the existent scientific literature.
The results of adherence for schizophrenia and bipolar disorder are similar to the ones found in scientific literature but differ from the ones for depression, being higher in our sample (Judit Lazary et al. Neuropsychopharmacol Hung 2021;23(4): 347-362). Moreover, in scientific literature it is found a similar prevalence of adherence across diagnosis (for schizophrenia, bipolar disorder and depression) whereas in our sample patients with depression showed a different and higher adherence to treatment (Judit Lazary et al. Neuropsychopharmacol Hung 2021;23(4): 347-362). In our sample, patients with personality disorders had the lowest adherence to treatment.

Introduction
Smoking prevalence in patients with mental illness ranges between two to 4 times higher than general population. This higher prevalence has a multifactorial origin, and some of the possible causes are still unknown.
They have a higher prevalence of tobacco-associated diseases and higher mortality.
Additionally, these patients have greater difficulty in treating and quitting smoking.
A relationship has been found between severity of mental illness and smoking. Risk of suicide seems to be higher in patients with higher tobacco consumption. Schizophrenia is the mental illness that has been most closely related to smoking, with a prevalence close to 90%.
ObjectivesThe aim of this work is reviewing the current bibliography referring to smoking treatments for patients with mental illness
MethodsA literature search using electronic manuscripts available in PubMed database published during the last ten years and further description and discussion of a single-patient clinical case
ResultsThe treatment of tobacco dependence in patients with mental illnesses is sometimes waited until there is psychiatric stability, which can take a long time in those cases with more severe mental disorders, which can have negative physical and psychiatric consequences.
The combined treatment of cognitive behavioral therapy and pharmacological treatment is the most effective approach. Nicotine replacement therapy can be useful, while combined use of antidepressants or anxiolytics is also recommended.
Bupropion has shown efficacy. In patients with schizophrenia it does not seem to worsen positive symptomatology, but improving the negative one. It should not be used in patients with bipolar disorder or bulimia.
Varenicline has shown efficacy in the general population, but limitations were established in patients with mental illness, although it is the drug that has shown greater efficacy. However, is not currently available in our country.
Cytisine is a drug with limited number of studies in the psychiatric population but it may be a reasonable treatment alternative.
ConclusionsThe prevalence of tobacco use in patients with mental illness is higher than the general population, especially in paranoid schizophrenia. The consequences on physical health and the evolution of psychiatric illness are very relevant. Based on above, a multidisciplinary and coordinated management involving psychiatrists and other specialists in the treatment of these patients should be desirable.

Introduction
TDuring COVID-19 pandemic, it was noticed that it was students who were mostly affected by the changes that aroused because of the pandemic. The interesting part is whether students’ well-being could be associated with their fields of study as well as coping strategies.
ObjectivesIn this study, we aimed to assess 1) the mental health of students from nine countries with a particular focus on depression, anxiety, and stress levels and their fields of study, 2) the major coping strategies of students after one year of the COVID-19 pandemic.
MethodsWe conducted an anonymous online cross-sectional survey on 12th April – 1st June 2021 that was distributed among the students from Poland, Mexico, Egypt, India, Pakistan, China, Vietnam, Philippines, and Bangladesh. To measure the emotional distress, we used the Depression, Anxiety, and Stress Scale-21 (DASS-21), and to identify the major coping strategies of students - the Brief-COPE.
ResultsWe gathered 7219 responses from students studying five major studies: medical studies (N=2821), social sciences (N=1471), technical sciences (N=891), artistic/humanistic studies (N=1094), sciences (N=942). The greatest intensity of depression (M=18.29±13.83; moderate intensity), anxiety (M=13.13±11.37; moderate intensity ), and stress (M=17.86±12.94; mild intensity) was observed among sciences students. Medical students presented the lowest intensity of all three components - depression (M=13.31±12.45; mild intensity), anxiety (M=10.37±10.57; moderate intensity), and stress (M=13.65±11.94; mild intensity). Students of all fields primarily used acceptance and self-distraction as their coping mechanisms, while the least commonly used were self-blame, denial, and substance use. The group of coping mechanisms the most frequently used was ‘emotional focus’. Medical students statistically less often used avoidant coping strategies compared to other fields of study. Substance use was only one coping mechanism that did not statistically differ between students of different fields of study. Behavioral disengagement presented the highest correlation with depression (r=0.54), anxiety (r=0.48), and stress (r=0.47) while religion presented the lowest positive correlation with depression (r=0.07), anxiety (r=0.14), and stress (r=0.11).
Conclusions1) The greatest intensity of depression, anxiety, and stress was observed among sciences students, while the lowest intensity of those components was found among students studying medicine.
2) Not using avoidant coping strategies might be associated with lower intensity of all DASS components among students.
3) Behavioral disengagement might be strongly associated with greater intensity of depression, anxiety, and stress among students.
4) There was no coping mechanism that provided the alleviation of emotional distress in all the fields of studies of students.

Introduction
Patients with mental disorders have a decreased life expectancy, being the main reason the cardiovascular disease. An important proportion of patients present a comorbid drug consumption. Amongst drugs, alcohol is the most frequent, and it is associated with a higher cardiovascular risk. The metabolic syndrome is one of the most employed tools to assess cardiovascular risk.
Objectives- To describe the demographic characteristics of the patients with an active alcohol consumption that were admitted to the hospital during the period of study.
- To describe the prevalence of metabolic syndrome in the sample, according to the Adult Treatment Panel III (ATP-III) criteria.
MethodsRetrospective observational study of three months duration. Data was collected from all patients admitted to the hospital during the period of study, with no specific exclusion criteria. Descriptive statistics were performed.
ResultsDuring the period of study 172 patients were admitted to the hospital (56.4% women and 43.6% men). A 44.8% presented alcohol consumption (25% sporadically, 6.4% weekly and 13.4% daily). Amongst women, 1% presented daily and 1% weekly consumption. Amongst men, 21.3% presented daily and 5.3% weekly consumption.
The prevalence of metabolic syndrome in the study sample was 29.11%. In the alcohol consumption group, the prevalence was 24.7% and differed according to the pattern of consumption: 43.5% in the daily consumption group, 27.3% in the weekly and 14% in the sporadically consumption group.
ConclusionsOn the one hand, in the sample of study a higher percentage of men present an active alcohol consumption, compared to women. It is remarkable the high percentage of daily alcohol consumption amongst men in our sample.
On the other hand, the prevalence of metabolic syndrome in our sample is similar to the one found in scientific literature regarding patients with mental disorders. It is noteworthy in our sample the increased prevalence of metabolic syndrome found in patients with a daily alcohol consumption, and a decreased prevalence in those with a sporadic pattern.

Introduction
We previously demonstrated that the difference between 11 PM and 8 AM TSH response to protirelin (TRH) tests on the same day (∆∆TSH test) is an improved measure in detecting hypothalamic-pituitary-thyroid (HPT) axis dysregulation in depression. This chronobiological index is normalized after successful antidepressant treatment.
ObjectivesThe present study aimed at assessing the effects of repetitive transcranial magnetic stimulation (rTMS) of the left dorsolateral prefrontal cortex (DLPFC) on the HPT axis activity in treatment resistant depressed inpatients (TRDs) (defined as having at least 2 treatment failures).
MethodsThe ∆∆TSH test was performed in 13 TRDs and 14 healthy hospitalized control subjects (HCs). To be enrolled in this study, patients had to show reduced ∆∆TSH values (i.e., < 2.5 mU/L) at baseline (BL). After 20 sessions of rTMS (using daily theta-burst stimulation; 100% resting motor threshold; number of pulses/session: 900), the ∆∆TSH test was repeated in all inpatients. The 17-item Hamilton depression rating scale (HAM-D) was used to assess the severity of depression. Remission was defined by a final HAM-D score ≤ 8.
ResultsCompared to BL, HAM-D scores decreased and ∆∆ TSH values increased after 20 sessions of rTMS (both p< 0.05 by T-test). There was a relationship between the reduction in HAM-D scores from BL to endpoint and the increase in ∆∆TSH values (rho = - 0.64; n = 13; p = 0.018). At endpoint, 7 patients showed ∆∆TSH normalization (among them 6 were remitters), while 6 patients did not normalize their ∆∆TSH (all were non-remitters) (p < 0.005 by Fisher Exact test).
ConclusionsOur results suggest that after 20 sessions of rTMS, chronobiological restoration of the HPT axis activity is associated with clinical remission. Further investigation of the specific effects of rTMS on the HPT axis activity in TRDs is warranted.

Introduction
Schizophrenia (SCH) and bipolar disorder (BD) are severe mental disorders which lead to psychotic, affective and cognitive symptoms and often cause a progressive functional deterioration of the individual. The current diagnosis of SCH and BD essentially depends on clinical observation that often leads to misdiagnosis and the introduction of non-specific treatments. Therefore, an early detection and intervention are determinant for a better prognosis. Improving outcomes of a First Episode of Psychosis (FEP) depends mainly on the identification of reliable and discriminatory biomarkers between both disorders.
ObjectivesGiven that oxidative stress has been tightly involved in multiple metal disorders, the major goal of this work was to characterize oxidative alterations in order to identify potential biomarkers which allow the differential diagnosis in an early stage.
MethodsThe study was carried out on samples from 49 subjects (14 women and 35 men), divided into four groups: a control group of 10 individuals not previously diagnosed with any serious mental disorder, 17 patients who had presented a FEP, 12 patients diagnosed with SCH and 10 patients diagnosed with BP. Biochemical analysis were conducted in erythrocyte fraction to characterize the cellular oxidative damage by measuring lipid peroxidation (LPO) levels and the antioxidant defense system by the evaluation of catalase (CAT) and superoxide dismutase (SOD) activities.
ResultsIn the present work, we observed a significant increase in LPO levels in both SCH and BD disorders that was not neutralized by the antioxidant defense. It was found that SCH patients, despite exhibiting greater activities of SOD and CAT compared to BD individuals, also showed significantly higher levels of oxidative damage. The differential oxidative profile observed between SCH and BD individuals allowed to perform an individually analysis of patients diagnosed with FEP. Although it was not possible to identify the type of psychotic disorder of all the patients with FEP, the results obtained showed that while several individuals exhibited an oxidative prolife similar to that observed in SCH patients, other individuals presented a prolife very similar to that found in patients with BD.
ConclusionsThe current work reveals that LPO is a potential indicator of worse prognosis after being differentially modified in both SCH and BD. Moreover, SOD and CAT have been identified, by presenting an opposite profile between patients with SCH and BD, as potential preliminary biomarkers for a discriminatory diagnosis in an early stage of the disorder.

Introduction
A review of the literature shows how female sex is a crucial factor in the development of ED, being the proportion of women and men 10 to 1 regardless of the location of the sample (Duncan, Ziobrowski & Nicol, 2017) and different clinical subtypes (AN, BN) (Swanson et al., 2011). However, male population has always been less studied, some works find that only 1% of the articles published in AN is aimed at the study of males (Galusca, 2012).
Nowadays it is accepted that the etiopathogenesis of these disorders is multifactorial and in addition to female gender other risk factors have been identified, such as neurobiological alterations, psychological predictors, personality traits, low self-esteem, extreme perfectionism or thinness values focused on body and figure. On the other hand, certain impulsive behaviours such as self-harm, substance use, physical activity or diets are factors that may be confused as predisposing or as symptoms of the pathology itself (Connan et al., 2003, Treasure, Stein and Maguire, 2015).
Recently, Kinasz, Accurso, Kass and Le Grange (2016) have compared the clinical characteristics that differentiate men (59) from women (560) in a sample of children and adolescents between 6 and 18 years-old, finding that males presented an earlier start of the ED and not appreciating differences in the duration of the disease, income, episodes of purgue and psychiatric comorbidity of anxiety, behaviour disorders or impulsivity.
ObjectivesThe aim of this study was to evaluate gender differences in clinical characteristics, levels of depression, previous obsessiveness and personality dimensions in eating disorders (ED) compared with controls.
MethodsA total of 80 participants was divided into 4 groups, 20 men and 20 women with ED and 20 men and 20 women without ED (healthy control), matched by age and socioeconomic status. The design of the study was case-control, and data was collected through clinical interview and a battery of cuestionaires.
ResultsMen with ED only differ in vigorous physical activity (measured by IPAQ) from controls and women with pathology. Regarding personality traits, men and women with ED do not differ among them, although they do differ in novelty search and harm avoidance respect to their controls.
ConclusionsBehaviors such as physical activity in males frame a slightly different way of reducing their discomfort, however, clinical implication indicates that the treatment may be similar according to gender.

Introduction
Thyroid disorders can present with psychiatric symptons similar to depression, and, at the same time, certain treatments, like litio, can cause changes in thyroid function. Given, therefore, the importance for the treatment and care of patients, the study of thyroid function is one of the parametres that should be requested in patients with psychiatric pathology.
ObjectivesTo study the frequency of thyroid disorders in patients who where admitted to a psychiatric short stay unit.
MethodsRetrospective descriptive observational study is carried out in the acute stay unit of a psychiatric hospital. As a sample, all patients admitted to the unit over a period of three months. During admission, their sociodemographic data, the treatment they receive and their diagnosis are recorded. Secondly, blood test are performed whith differents parameters, including TSH values.
ResultsIn the total sample of 172 patients, 8 of them have TSH abnormalities. 7 of them, all women, present hypothyroidism values.
A single male patient presented values of hyperthryroidism.
ConclusionsAccording to the present study, 4,6% of the patients present alterations at the TSH at admission, although except in one case, the values were not markedly altered.
The thyroid study at admission allows detecting cases of altered TSH that are amenable to treatment and monitoring.

Introduction
Incidence of alcohol abuse in our country is high, although it is still under-diagnosed and under-treated. The WHO estimates that a total of 3.3 million deaths worldwide per year are related to alcohol consumption.
ObjectivesThe main objective is to describe the pattern of alcohol consumption in a sample of patients who are admitted to our psychiatric hospital for different reasons, relating with previous diagnoses.
MethodsA retrospective observational descriptive study was carried out in the acute care unit of the psychiatric hospital, after approval of the corresponding protocol by the ethics committee. All patients admitted to this unit during a three-month period were taken as a sample. During admission, sociodemographic data, drug use, treatment type and time and previous diagnoses were collected.
ResultsOut of 172 patients, 81 reported being abstemious, 45 declared occasional consumption, 11 weekly and 22 daily consumption. There is no data about 13 patients. Among those who reported daily alcohol consumption, 59% had a previous diagnosis of Substance Use Disorder (SUD), 23% a previous diagnosis of Schizophrenia, 13.5% of Bipolar Disorder and finally 4.5% of Depressive Disorder. All the patients with a previous diagnosis of SUD reported consumption of more than 10 SDUs/day, the group with Schizophrenia stated less than 5 SDUs/day, of the group with T. Bipolar between 7-10 SDUs/day and with T. Depressive 5 SDUs/day.
ConclusionsThe results obtained are consistent with the literature in relation to the under-diagnosis of alcohol use disorder, taking into account that 40% of patients in the sample with daily alcohol consumption previously had not such a diagnosis and it was not recorded in their medical history. For this reason, and for the sake of being able to treat them, it is essential to question all patients about alcohol consumption, whatever the reason for their admission.

Introduction
One of the great challenges still to be achieved in schizophrenia is the development of a staging model that reflects the progression of the disorder. The previous models suggested have been developed from a theoretical point of view and do not include objective variables such as biomarkers, physical comorbidities, or self-reported subjective variables (Martinez-Cao et al. Transl Psychiatry 2022; 12(1) 1-11).
ObjectivesDevelop a multidimensional staging model for schizophrenia based on empirical data.
MethodsNaturalistic, cross-sectional study. Sample: 212 stable patients with Schizophrenia (F20). Assessments: ad hoc questionnaire (demographic and clinical information); psychopathology: PANSS, CDS, OSQ, CGI-S; functioning: PSP; cognition: MATRICS; laboratory tests: C-Reactive Protein (CRP), IL-1RA, IL-6, Platelets/Lymphocytes (PLR), Neutrophils/Lymphocytes (NLR), and Monocytes/Lymphocytes (MLR) ratios. Statistical analysis: Variables selection was performed with an ad hoc algorithm developed for this research. The referred algorithm makes use of genetic algorithms (GA) to select those variables that show the best performance for the patients classification according to their global CGI-S. The objective function of the GA maximizes the individuals correct classification of a support vector machines (SVM) model that employs as input variables those given by the GA (Díez-Díaz et al. Mathematics 2021; 9(6) 654). Models performance was assessed with the help of 3-fold cross-validation and these process was repeated 10,000 times for each one of the models assessed.
ResultsMean age(SD): 39.5(13.54); men: 63.5%; secondary education: 59.50%. Most patients in our sample had never been married (74.10%), and more than a third received disability benefits due to schizophrenia (37.70%). The mean length of the disease was 11.98(12.02) years. The best SVM model included the following variables: 1)Clinical: number of hospitalizations, positive, negative, depressive symptoms and general psychopathology; 2)Cognition: speed of processing, visual learning and social cognition; 3)Functioning: PSP total score; 4)Biomarkers: PLR, NLR and MLR. This model was executed again 100,000 times applying again 3-fold cross-validation. In 95% of the algorithm executions more than a 53.52% of the patients were classfied in the right CGI-S category. On average the right classification was of 61.93%. About specificity and sensitivity the average values obtained were of 0.85 and 0.64 respectively.
ConclusionsOur staging model is a robust method that appropriately distributes patients according to the severity of the disorder. Highlights the importance of clinical, functional and cognitive factors to classify patients. Finally, the inflammatory parameters PLR, NLR and MLR have also emerged as potential biomarkers for staging schizophrenia.

Current procedures for ranching and sustainable use of guanacos necessitate their transport. Transportation is a risky process for animals, and is a particular concern for wild-caught or semi-domesticated species such as the guanaco — a wild South American camelid species increasingly being established on farms in Chile and Argentina. This study investigated the effect of transport on the physiological and behavioural responses of eight castrated adult male guanacos, transported on a single 2 h journey at a stocking density of 113.5 kg m-2 (0.76 m2 per animal). Plasma cortisol and blood glucose concentration, total and differential white blood cell (WBC) counts, heart rate, and body weight were measured one week before, immediately before, immediately after, 2 h after and one week after transport. Behavioural responses were recorded during handling prior to loading. Immediately after transport we found significant increases in plasma cortisol concentrations and neutrophil:lymphocyte (N:L) ratio, the latter peaking 2 h after transport. Heart rate increased significantly only during loading, while body weight remained constant throughout. Behavioural responses related to handling (jumping, vocalising, kicking, spitting and urinating) were not associated with the physiological response. All variables returned to pre-transport values within one week. Transport of guanacos under these conditions produced physiological changes similar to those associated with a mild and transient stress response in other species and which, we judge, fall comfortably within acceptable limits for their welfare.

Background
Electroconvulsive therapy (ECT) is an effective and safe medical procedure that mainly indicated for depression, but is also indicated for patients with other conditions. However, ECT is among the most stigmatized and controversial treatments in medicine. Our objective was to examine social media contents on Twitter related to ECT to identify and evaluate public views on the matter.
MethodsWe collected Twitter posts in English and Spanish mentioning ECT between January 1, 2019 and October 31, 2020. Identified tweets were subject to a mixed method quantitative–qualitative content and sentiment analysis combining manual and semi-supervised natural language processing machine-learning analyses. Such analyses identified the distribution of tweets, their public interest (retweets and likes per tweet), and sentiment for the observed different categories of Twitter users and contents.
Results“Healthcare providers” users produced more tweets (25%) than “people with lived experience” and their “relatives” (including family members and close friends or acquaintances) (10% combined), and were the main publishers of “medical” content (mostly related to ECT’s main indications). However, more than half of the total tweets had “joke or trivializing” contents, and such had a higher like and retweet ratio. Among those tweets manifesting personal opinions on ECT, around 75% of them had a negative sentiment.
ConclusionsMixed method analysis of social media contents on Twitter offers a novel perspective to examine public opinion on ECT, and our results show attitudes more negative than those reflected in studies using surveys and other traditional methods.
