Chemsex refers to the use of drugs, typically stimulants and/or psychoactive substances, in a sexual context, often in the context of casual or group sex encounters. Currently, the practice of chemsex focuses on men who have sex with men (MSM). On the other hand, Pre-exposure prophylaxis (PrEP) is a biomedical method that has proven effective in preventing HIV transmission, particularly among individuals at a heightened risk, including those who engage in chemsex. MSM account for two thirds of new HIV cases in the US. It is estimated that in 70% of cases seroconversion occurs through “condomless anal sex” (CAS). According to the CDC, one in six MSM will be infected with HIV during their lifetime. The consumption of methamphetamine (MA) has been identified as the main driver of the practice of CAS, alteration of rectal immunological function and faster seroconversion. One in three new HIV infections have been associated with MA consumption. (Grov C et al. JAIDS 2020; 85 272-279).

The primary goal of this study is to describe the prevalence of chemsex engagement among PrEP users, delineate user characteristics and requirements, gain deeper insights into this phenomenon within the Barcelona region, and formulate customized strategies accordingly.

This study conducts a literature review to explore the current correlation between engaging in chemsex and the utilization of PrEP. We identified research articles published between January 2020 and December 2022, that discussed the utilization of chemsex drugs prior to or during sexual activities. The findings were synthesised using a narrative approach and conceptualised using a behavioural analysis framework.

According to a recent cross-sectional study performed at Hospital Clínic de Barcelona, SUD among patients who are being followed-up in the outpatient clinic of PrEP was higher (89%) compared with other European regions such as England (38.5%) or Amsterdam (41%). Moreover, according to data collected in the EMIS 2017 survey, Barcelona is the city with the highest prevalence of chemsex in Spain. (De La Mora L et al. AIDS Beh. 2022; 26: 4055-4062).

The frequency of chemsex practice among individuals using PrEP in Barcelona surpasses what has been observed in other groups. Nearly 25% of the participants express worries and a requirement for assistance regarding the management of drug use, matters associated with their sexuality, and sexually transmitted infections (STIs). MSM who suffers from substance use disorder may experience difficulty achieving effective daily oral PrEP adherence prevention levels that may serve as early indicators of increased risk of disengagement from PrEP care and discontinuation the PrEP. These results highlight the importance of adopting aninterdisciplinary approach that incorporates education about substances and the implementation of risk mitigation strategies within the context of riskier sexual behaviors.

Yoga has been demonstrated to have a range of beneficial effects on individuals with substance use disorders, including opioid use disorders. We initiated a randomized clinical trial to find out the efficacy of add-on yoga among patients with opioid dependence stabilized on treatment to find out whether it led to improvement in sleep and quality of life. However, the rate of enrolment into the study was quite low.

In this interim analysis, we present the preliminary data on the reasons for non-enrolment in the yoga trial.

The single-centre trial involved 1:1 randomization of patients with opioid dependence stabilized on medications (naltrexone or buprenorphine) for a period of at least 4 weeks into two groups (add-on yoga or wait-list control). The yoga included asanas and panchakosha meditation, taught for a period of 7 days and to be practiced by the participants for a period of 12 weeks. We recorded the reasons for non-participation among those who did not participate and asked them questions about their views on yoga.

Of the 310 patients recruited between August 2022 and July 2023 (99.7% male, mean age 34 years, 56.5% married), 255 (82.3%) could not be enrolled in the trial. The most common reasons for non-enrolment were not having time for training (n = 206, 80.8%), not having time for doing yoga (n = 180, 70.6%), not having a smartphone for continued training or contact (n = 31, 12.2%), distance from the center (n = 17, 5.5%) do not feel the need for yoga (n = 16, 5.2%), injury or disability (n = 9, 3.5%), old age or medical condition (n = 7, 2.7%), already doing gym exercises (n = 7, 2.7%), nature of job (n = 5, 2.0%), do not have knowledge of yoga (n = 5, 2.0%), and do not think yoga would be useful (n = 4, 1.6%). Among those who could not be enrolled, 35.1% reported doing yoga sometime in the past, and 21.6% reported that at least one of the family members did yoga. When asked whether they would be interested if yoga was available online, 16 (5.2%) responded ‘yes’ and 45 (14.5%) responded ‘maybe’.

Expressed time constraints may be an important factor deterring patients with opioid dependence from engaging in yoga as an add-on yoga. There are other reasons as well that may deter patients from such an intervention. The findings should be seen in the light of the limitation of a single medically oriented center, and patients already stabilized on treatment.

Several studies have called atention to the mental health disorders associated with chemsex -the intentional use of drugs before or during sexual intercourse GBMSM (gay, bisexual and men who have sex with men) population-. Sexualized intravenous drug use is also known as slam or slamsex. There are few studies that analyze the mental health differences between intravenous drug users compared to non-intravenous drug users in chemsex context.

We aim to describe the mental health outcomes including current and past anxiety disorders diagnosis in a sample of users with sexualized drug use (chemsex) attended by the non-governmental organization Apoyo Positivo in the program “Sex, Drugs and You” and to compare the differences of current and previous diagnosis of anxiety disorders between intravenous drug users compared to non-intravenous drug users.

A cross-sectional descriptive analysis of a sample of users attended by the non-governmental organization Apoyo Positivo in the program “Sex, Drugs and You” between 2016-2019 was performed.

We included 217 participants. Current or past diagnosis of anxiety disorders was found in 142 participants. Anxiety disorders were significantly higher in the intravenous drug use group compared to the non-intravenous drug use group (p<0.05).

Previous studies have reported that MSM who practiced chemsex were more likely to experience from anxiety. In our study, anxiety disorders where higher in participantes who engaged in intravenous drug use. A multidisciplinary team is necessary to address chemsex and provide care and treatment for mental health problems such as anxiety, depression, suicidal behaviour or drug-induced psychosis.

Knee osteoarthritis is one of the most common causes of functional impairment, significantly impacting patients’ quality of life and leading to severe mood disorders. Our objective is to assess the prevalence of depression and anxiety in knee osteoarthritis patients.

Evaluate the prevalence of depression and anxiety in patients with knee osteoarthritis.

This was a cross-sectional study conducted over a three-month period from February to April 2022, including consecutive patients who consulted in a Rheumatology department. We assessed each patient using a validated version of the HAD (Hospital Anxiety and Depression) scale, which includes 14 items, each rated from 0 to 3, measuring two components: depression and anxiety.

We enrolled 82 patients (67 women and 15 men) with an average age of 60.4 years [44-89 years]. The average disease duration was 10 years [2-30]. Knee osteoarthritis was bilateral in 79% of cases. Knee deformities were observed in 74.4% of cases (40.2% had genu valgum, and 29.3% had genu varum). Radiological assessment showed that most of our patients were at Kellgren-Lawrence (KL) stage 3 (50%). All patients received analgesics, with 92.7% receiving NSAIDs, 67.1% local corticosteroid infiltrations, and 18.3% hyaluronic acid injections. The mean visual analog scale (VAS) score was 6.9 out of 10 [1-10]. The mean anxiety score was 7.5 [4-16], with 25.4% of patients exhibiting no anxiety symptoms (score ≤7), 40.3% displaying doubtful anxiety symptomatology (score between 8 and 10), and 34.3% having certain anxiety symptomatology (score ≥11). The mean depression score was 9.6 ± 4 [0-19]. 40% of patients had no depressive symptoms (score ≤ 7), 53.3% had doubtful depressive symptoms (score between 8 and 10), and 6.7% had certain depressive symptoms (score ≥11). The statistical analysis revealed a significant association between anxiety scores and KL stage, but no association with age, sex, mobility limitation, or VAS. Regarding depression, there was no significant association with epidemiological, clinical, or radiological parameters of knee osteoarthritis.

Although knee osteoarthritis may appear to be a benign pathology, its impact can be severe, including depression and anxiety. These mood disorders are primarily influenced by the disease stage. Therefore, psychological care is sometimes necessary in the management of these chronic degenerative diseases.

Engaging in moderate physical activity holds a vital role in our daily lives, serving as both a means of social recreation and a fundamental contributor to physical and mental wellbeing. It is also worth noting that such activity can potentially produce mood-enhancing effects by promoting neurogenesis and neuronal adaptability. Intriguingly, certain individual psychological traits such as rituals, compulsions, obsessional thinking, and superstitious beliefs, as well as inflexibility in daily routines, appear to serve a purpose in competitive athletic endeavors.

The aim of our study was to investigate the possible presence of obsessive-compulsive symptoms or disorders, as well as of superstitions or magical thinking, in a group of professional tennis players, by means of standardized assessment scales, as compared with healthy subjects who did not professionally perform any kind of sport activity.

Twenty-five current or former professional tennis were recruited within the Italian Tennis Federation during an international competition and during a master meeting of coaches. All of them underwent a psychiatric interview with a structured scale and a psychopathological assessment carried out with the Mini-International Neuropsychiatric Interview (MINI) and the Yale-Brown Obsessive-Compulsive Scale (Y-BOCS). Data were analyzed and compared.analysis was performed by means of contingency tables, χ² tests, group statistics, paired, independent and Mann Whitney’s tests.

The Y-BOCS total score was significantly higher in both current and retired athletes than control subjects (5.96 ± 5.76 versus 1.24 ± 2.65, p = 0.001, t = 3.72). Current athletes showed more frequently current aggressive obsessions (χ2 = 0.041, r = 5.24) and current miscellaneous compulsions (χ2 = 0.030, r = 5.94) than past athletes. The Y-BOCS (t = 3.4, p = 0.002) obsessions (t = 3.48, p = 0.002), and compulsions subscale (t = 3.11, p = 0.005) scores were higher in current players than in the other group.

Our results support the hypothesis that high-level competitive sports activities, which suppose compliance with strict daily routines and extensive training, could constitute a risk factor for the onset of full-blown obsessive-compulsive disorder in more vulnerable subjects. Similarly, there is a growing demand for sport psychological support experts in order to prevent high stress in training and competitions.

The time period between the onset of a mental disorder and its first adequate treatment (duration of untreated illness - DUI) influence long-term prognosis and outcome in patients with severe mental disorders. The relationship between DUI and outcome was originally found in people affected by schizophrenia spectrum disorders, however in patients with Obsessive-Compulsive Disorder (OCD) DUI is significantly longer compared with that of patients with other severe mental disorders, such as schizophrenia and bipolar disorder.

Aims of the present study is to assess the impact of DUI on long-term outcomes in OCD patients across published studies.

A systematic review was carried out by selecting relevant articles on the topic present in three common on-line databases, such as PubMed, APA PsycInfo, and Scopus, up to June 2023.

Among included studies, DUI ranged from 7,0±8,5 to 20,9±11,2 years. Patients reporting a longer DUI have a poor long-term outcome, in terms of greater symptom severity and lower level of treatment response, whether pharmacological treatment or psychotherapy or a combination of these two. This is particularly true when the onset of the disease is insidious and subthreshold. However, there are severe early-onset forms of OCD in which the request for help is anticipated due to the severity of the symptoms, the DUI is shorter, but the prognosis is still negative.

The present review confirms that longer DUI has a negative impact on the long-term outcome of patients with OCD. Furthermore, it is reasonable to hypothesize that cultural factors, such as the perception of the disease and the ability to access treatment, may result in a prolongation of the DUI. All these elements cannot be evaluated in our review due to the paucity of studies on the topic. Future studies could be useful to better understand the causes of a longer DUI, to guide and to promote the dissemination of early interventions with a specific focus on OCD symptoms.

Instrumental learning involves goal-directed and habitual systems. The Slips-of-Action Task (SOAT) is extensively used to measure habit tendencies and the likelihood of making erroneous responses for devalued outcomes. The SOAT provides a Devaluation Sensitivity Index (DSI), a measure of the balance between relative goal-directed and habitual learning. Individuals with Obsessive-Compulsive Disorder (OCD) often engage in repetitive actions, suggesting a potential deficit in goal-directed control and an increased reliance on habitual learning. Previous literature has shown that medicated OCD adults performed worse on the SOAT task than healthy controls.

To compare habit learning performance in an unmedicated sample:

• - Goal 1: Between OCD and Healthy Controls (HC)

• - Goal 2: Across four groups: adult OCD, adult HC, children OCD, and children HC

Participants: Eighty-three participants (44 OCD patients and 38 healthy controls) completed the study with usable task data. The 44 OCD patients comprised 17 adults (mean age: 26.76 years, SD: 8.61 years) and 27 children/adolescents (mean age: 12.84 years, SD: 2.59 years). The 38 healthy controls included 17 adults (mean age: 30 years, SD: 7.49 years) and 21 children/adolescents (mean age: 14.1 years, SD: 2.19 years). All participants were unmedicated. Measures: Participants completed an adapted version of the “Fabulous Fruit Game”, which included an instrumental training phase to learn Stimulus-Response-Outcomes (S-R-O) associations and a SOAT to assess the strength of learned S-R-O associations. DSI was calculated by subtracting the percentage of responses made toward devalued outcomes from the percentage of responses made toward still valuable outcomes. Behavioral Analyses: Student’s t-test comparing individuals with OCD to HC and a ONEWAY ANOVA to examine group differences across multiple categories.

Goal 1: DSI comparison between individuals with OCD and HC revealed a significant difference, with HC demonstrating superior performance (t (60.9) = 2.60, p = .012, Cohen’s d = .546). Goal 2: The overall DSI comparison across adult OCD, adult HC, children OCD, and children HC showed a non-significant difference (F(3) = 3.407, p = 0.22). However, post hoc analysis revealed significant differences between Adult HC and Youth OCD (I-J Scheffe = 28.82, p = .033), indicating superior performance in adult HC.

This study highlights altered Habit Learning in unmedicated OCD individuals, supported by significant DSI differences compared to HC. Age-related distinctions were observed, emphasizing the need for age-sensitive interventions in understanding and addressing habit-related challenges in OCD.

Neuropsychiatric disorders can develop following a group A β-hemolytic streptococcal infection, through autoimmune inflammation of the nervous system. Sydenham’s chorea and PANDAS (Pediatric Autoimmune Neuropsychiatric Disorders Associated with Streptococcal Infection) are the two most well-known syndromes, primarily affecting children but rarely observed in adults.

Our aims are to contribute to the scientific understanding of adult PANDAS-like syndrome and provide a comprehensive literature review on the subject.

Case report using clinical records and a non-systematic literature review.

A 24-year-old female presented to the emergency department with profound emotional distress triggered by intrusive thoughts of existential dread, accompanied by compulsive praying. She reported that these symptoms had commenced five days earlier. Two days prior to the onset of her obsessions, she had experienced a high fever, odynophagia, cough, and chills and received an empirical diagnosis of tonsillitis following a physical examination. She was prescribed antibiotics with good response. She revealed that she had experienced two prior episodes of similar anxiety and obsessions when she was approximately seven years old.

She developed acute obsessive thoughts, including doubts about the meaning of her life, and engaged in compulsive prayer and seeking reassurance from relatives. Notably, there were no signs of affective, dissociative, or psychotic disorders during her admission to the ED or in the preceding months. She reported suffering from anxiety, insomnia, and loss of appetite in the past five days but did not express any suicidal ideation.

Physical examination indicated mild laryngeal erythema, and laboratory tests showed non-specific signs of infection with no further significant findings. Symptoms were alleviated within a week, aided by treatment with benzodiazepines (lorazepam 1 mg/8h), and she did not require further psychiatric counselling.

It is worth noting that adult patients can experience a PANDAS-like reaction after a streptococcal infection and may also undergo symptom relapse following new immunological challenges upon reinfection. The existence of a PANDAS spectrum has been postulated, encompassing various manifestations. Thus, when presented with acute obsessive symptoms, healthcare providers should consider this diagnosis, inquire about previous episodes, and conduct a comprehensive medical history and etiological assessment.

The Contrast Avoidance Model (CAM) was developed to explain pathological worry in generalized anxiety disorder (GAD). The CAM posits that those with GAD are sensitive to sharp increases in emotions, and use worry to maintain heightened states of negative arousal to avoid these emotional shifts. Research has widely supported the CAM in the conceptualization of GAD, and has extended these findings to other disorders, including major depressive disorder (MDD) and social anxiety disorder (SAD). Despite the utility of the CAM model in informing the etiology of these conditions, research has yet to expand these findings beyond GAD, MDD, and SAD. Specifically, obsessive-compulsive disorder (OCD), which co-occurs with GAD, MDD, and SAD in adults at a rate of 15.0%, 40.7%, and 14.7%, respectively, and shares many of their etiological features, has yet to examined in the context of the CAM. Thus, examining CA as a relevant mechanism and therapeutic target for OCD is an unstudied conceptual framework that may offer meaningful clinical utility.

The present study used receiver operator curve (ROC) analyses to examine the predictive utility of the CAQ-W and CAQ-GE in detecting probable OCD in a large undergraduate sample. We hypothesized that the CAQ-W and CAQ-GE would be higher in participants with probable OCD and would offer sufficient sensitivity and specificity in predicting probable OCD.

1259 undergraduates were recruited for a mass University screening. Participants were included in the OCD group (N = 291) if they met diagnostic criteria for OCD (DOCS total score > 20). Participants were included in the nondisordered group (n = 249) if they did not meet diagnostic criteria for any of the screened disorders (SAD, MDD, GAD, OCD, panic disorder, post-traumatic stress disorder, OCD, borderline personality disorder), denied suicidality, and denied receiving mental health treatment in the last 12 months. ROC analyses were used to examine the accuracy of the CAQ-W and the CAQ-GE in detecting probable OCD.

Results of ROC analyses are reported in Table 1. AUC values for the CAQ-W and CAQ-GE were significantly different from the null hypothesis (AUC = .50, p < .001), and demonstrated excellent (.89) to outstanding (.91) accuracy in predicting probable OCD (Figure 1), respectively. Optimal sensitivity and specificity to detect probable OCD (Table 2) was achieved at a cut off score of 67.5 for the CAQ-W (Sensitivity = 81.4%; Specificity = 82.3%) and a cutoff score of 43.5 for the CAQ-GE (Sensitivity = 84.9%; Specificity = 85.5%).

Results suggest that OCD can be accurately characterized by CA. Findings also highlight the utility of examining CA as a relevant maintenance factor for OCD symptoms. Future research should examine the impact of CA on OCD symptoms in-laboratory and ecological settings.

The Strengths and Difficulties Questionnaire (SDQ) is a widely used assessment tool for measuring the psychological well-being of children and adolescents. It consists of 25 items that assess emotional symptoms, conduct problems, hyperactivity/inattention, peer relationship difficulties, and prosocial behavior.

The present study aimed to investigate the relationship between parental perceptions of difficulties and the results obtained from the SDQ.

Participants were recruited from the initial consultation of Child and Adolescent Psychiatry (N=132). Parents completed a questionnaire assessing their subjective perceptions of their child’s difficulties in various domains (home, school, learning activities, relations with friends) on a 4-point scale ranging from “no notion of difficulties” to “very severe difficulties”. They also completed the SDQ scale. Data were analyzed using SPSS software.

In this study, 74% of participants had scores on the SDQ indicating potential psychological difficulties. Additionally, 17.4% of participants had scores on the borderline between normal and abnormal results. 47% of patients scored above the cut-line for problems on the hyperactivity/inattention subscale, indicating higher levels of difficulties in this area. Conversely, only 3% of participants scored problematic scores on the peer relationship difficulties subscale. There was no statistical difference between sexes in terms of SDQ scores. A correlation analysis revealed a significant positive correlation (p < 0.01) between parental perceptions of difficulties and higher SDQ scores and the mean score on the SDQ scale was found to be significantly higher in patients who were rescheduled for another consultation following the evaluation by doctors, compared to those patients who received clinical discharge from the initial consultation (p-value 0,040).

This study provides valuable insights into the concordance between parental perceptions and objective assessments of difficulties in children and adolescents. Parents who perceived their child to have more difficulties also reported higher levels of psychological difficulties on the SDQ. This study highlights the importance of using tools like the SDQ to assess psychological well-being in children and adolescents. It also emphasizes the practical utility of the SDQ as a time-efficient assessment tool for use during initial consultations in child and adolescent psychiatry.

The issue of screen time usage among children has become a contentious topic for parents in contemporary society. While electronic devices offer undeniable benefits, their inappropriate use can lead to substantial mental and physical health challenges for children. Parents are tasked with the responsibility of equipping themselves and their children with the knowledge and skills necessary for mindful electronic device use.

This study aims to assess the awareness levels of mothers regarding their children’s screen time usage and to promote mindful screen usage. It also aims to understand the reasons behind parents’ decisions to allow their children access to electronic devices.

An adapted short online screen-time questionnaire (Vizcaino et al 2019), was distributed through online Google forms, primarily to mothers residing in India. The questionnaire comprised of ten questions encompassing topics related to the child’s background, mothers’ awareness and patterns of screen-time usage.

213 mothers with children aged one year to 17 years responded. 157 mothers (73.7%) were in employment (104 were working in an office, 32 were working from home and 18 were freelancing). 121 mothers had >one child. Majority of the mothers (n=170, 79.81%), believed that children should have <one hour screen-time. However, they also admitted that majority of their children spent >one hour per day screen-time. The usage was more during weekends (>one hour=161, 75.58%) than weekdays (>one hour = 145, 68%)(p=0.021). Weekend screen-time was more in children whose mothers were employed (p=0.006). There is a significant increase in weekday (p=0.044) and weekend (p=0.006) screen-time usage as the child’s age increased. Children predominantly watched television, followed by mobile phones and tablets. Except for 29 children, the rest enjoyed interacting with other people (54 with everyone, 73 with only family members and 57 only for some time). The primary context in which children engaged with electronic devices was while they were being fed/ meals-time (n = 114,54%) or when the mothers were busy with household chores (n = 85,40%).

Despite maternal awareness about healthy screen-time, majority of the children were allowed to use higher screen-time. Efficient strategies should be imparted to parents to change the current practices of using digital-media as pacifier or distractor to mindful screen-time including usage for educational purposes.

Rumination is a transdiagnostic phenomenon that is linked to psychological and physical symptoms not only in adulthood but also in childhood. Several distal and proximal factors are believed to underlie the development of ruminative tendencies, with parental characteristics and modelling being among those with a potential association with the increased levels of children’s rumination.

The primary aim of the study was to investigate the link between rumination in children and parental functioning, including rumination, worry and depressive symptoms. Additionally, we aimed to test the association between rumination and psychological and somatic health in a sample of healthy children and early adolescents.

153 children (87 girls, mean age = 10.74; SD = 0.91 years) and their parents (130 females, mean age = 42.65; SD = 4.08 years) participated in the study. For children, Kid Rumination Interview (KRI; Baiocco et al., 2017) was used, alongside the assessment of nine subjective health complaints. KRI employes 4 images to measure the frequency of rumination. Self-reported questionnaires were also completed by parents to report on worry, rumination, and depressive symptoms.

Contrary to our expectations, there was no significant association between children’s rumination and parental rumination (r = .06, p = .506), worry (r = -.02, p = .850) and depressive symptoms (r = -.01, p = .979). Psychosomatic complaints in children exhibited a positive albeit weak association with parental depressive symptoms (r = .17, p = .046). Regression analysis revealed that the frequency of rumination occurring in the four situations associated significantly with psychosomatic symptoms (β = .266; t = 3.321; p = .001) after controlling for sex and age.

Our findings are in line with previous studies demonstrating the relationship between rumination and psychosomatic symptoms in older adolescent samples. However, parental perseverative cognitions and depression were unrelated to ruminative tendencies in children. Nevertheless, the modest sample size and the employment of a different assessment approach compared to self-report questionnaires may have influenced our findings.

juvenile chronic depression is characterized by high prevalence, difficulties in diagnosis, nosological qualification and prognostic assessment. According to epidemiological data, the frequency of these conditions ranges from 1.5% to 3% in the general population (Gutiérrez-Rojas et al. Braz. J. Psychiatr 2020; 42 657-672), and among all depressions in adolescence, a chronic course develops in about 20% of cases (Blanco C., 2010 et al. The J clinical psychiatry 2010; 71(12) 6501). Due to the polymorphism of the clinical picture and the peculiarities of juvenile ontogenesis, difficulties arise in nosological and prognostic assessment.

to study the long-term prognosis of chronic depression, depending on the variant of its course.

Catamnestic examination was performed on 64 patients of adolescent age (16-25 years), for chronic depressive state lasting more than two years (F31.3, F31.4, F32 (except F32.3), F33 (except F33.3), F34, F34.1, F21, F20 according to ICD-10). The duration of the catamnesis is more than 10 years. The PSP scale was used for psychometric assessment.

when analyzing the ten-year course of juvenile chronic depression, three variants were identified: regredient (23.4%), monotonous (35.9%) and progredient (40.6%). The regredient course was characterized by a marked reduction or disappearance of psychopathological disorders with the formation of further remission with a high level of functioning in all spheres of life and complete social and labor adaptation (81-100 points on the PSP scale). The monotonous course was characterized by low variability and insignificant dynamics of individual manifestations throughout the disease with the preservation or some decrease in the level of educational and labor adaptation with the restoration of previous social contacts and a fairly high quality of life (scores 61-80 on the PSP scale). The progressive course was characterized by the gradual addition of new psychopathological disorders, or the aggravation of existing ones, patients had a distinct decrease in educational, labor and social adaptation (scores 50-31 on the PSP scale) or complete maladaptation of all spheres of life (scores <40 on the PSP scale).

The high incidence of progressive and monotonous course in juvenile chronic depression, contributing to a decrease in the level of functioning of patients, indicates the importance of timely detection of these conditions and the need for careful selection of therapy.

Emotional dysregulation are considered early manifestations of neuropsychiatric disorders. Recent research has shown that a threatened preterm labour (TPL) represents an adverse prenatal event that involves temperament disturbances, even in absence of prematurity. Thus, full-term TPL infants at 6 months of age are characterized by lower positive affect, higher negative affect, and worse emotional regulation relative to a full-term non-TPL control group.

The aim of this study is to explore the predictors of change of emotional infant competences.

This prospective cohort study recruited mothers who suffered from a TPL. Infants’ temperament assessment was performed at 6 and 30 months of age using the Rothbart Behaviour Questionnaires, examining positive affectivity/surgency, negative emotionality, and orienting and emotional regulatory capacity. A regression model was carried out, including gestational age at birth, maternal anxiety trait, maternal history of psychological traumas, prenatal and postnatal maternal depression, anxiety, and cortisol as well as parenting stress as predictors.

Increased positive affectivity was related with lower paternal stress (p = .044). Maternal history of trauma and parenting stress was associated with increased negative emotionality (p = .037 and p = .045, respectively). Increased emotional regulation disturbance was linked to low gestational age at birth (p < .001), higher postnatal depression (p = .002), higher prenatal anxiety at TPL diagnosis (p = .039) and higher postnatal anxiety (p = .008).

Therefore, maternal previous traumas, maternal psychopathology from pregnancy to postpartum as well as parenting stress should be considered in psychological treatment to improve infant’s emotional competences and prevent subsequent neuropsychiatric disorders.

Friendships are vital relationships throughout the lifespan, but become especially meaningful during adolescence. Adolescents between the ages of 10 and 18 name a friend as one of the most important people in their lives (Kiesner et al., 2004). Authentic social groups, defined as mutual social relationships that adolescents voluntarily engage in, are sources of support and companionship for adolescents, more than parents (Furman & Buhrmester, 1992). Past research shows adolescents turn to their friends most for mental health support in a crisis, yet less than half report finding the support helpful (Geulayov et al., 2022). Thus, it’s crucial to understand friendship dynamics of adolescents in order to address an appropriate intervention. Past literature has demonstrated gender differences in how adolescents approach friendships and social relationships (Lempers & Clark- Lempers, 1993).

I aim to investigate whether girls, boys, and gender non-binary individuals differ in their perceptions of friendship quality and friendship dynamics (i.e. social support seeking) and whether these differences have implications for their mental health outcomes. By studying gender differences in friendship quality and mental health, I hope to shed light on potential avenues for promoting inclusivity and positive mental health outcomes for both gender binary and gender non-binary adolescents.

A cross-sectional survey (OxWell) was administered online to students across secondary schools and further education colleges in England to assess their self-reported friendship quality. The RCADS and WEMWBS scales were used to assess depression and anxiety symptomology, and well-being, respectively. The results from the survey were analysed in R.

Gender-binary and gender non-binary adolescents differed in friendship quality, friendship dynamics, mental health scores, and help-seeking behaviours. Gender non-binary adolescents had the worst mental health scores and reported lowest friendship quality compared to girls and boys. Boys had the best mental health when compared to girls and gender non-binary adolescents, and were more likely to perceive support provided by their friends as helpful. Surprisingly, gender non-binary adolescents reached out to their friends the most (when compared to girls and boys) for mental health support, despite having proportionally lower quality friendships, and were the least likely to find support received from friends helpful.

This data presents evidence for the difference in social relationships across adolescents of all genders. It highlights the need for specialized and inclusive mental health support being made available for gender non-binary youth in England—a minoritized group in need of intervention. This data hopes to inform school-based friendship interventions targeted to improve friendships and mental health of gender non-binary youth.

Mental health professionals pay particular attention to adolescents, as many psychiatric disorders begin at this age, and the mental state of adolescents has been deteriorating worldwide in the last decade. Based on previous international research, the ability to regulate negative emotions and mentalizing - that is, the ability to identify the thoughts and emotions behind one’s own and others’ behaviour - mediate the negative effects of attachment difficulties experienced in close relationships on the quality of life. This relationship has not yet been investigated among Hungarian adolescents. Adolescent events can have a long-term effect on a person’s mental health, so it is very important to examine the factors that influence the quality of life.

This research aimed to examine the relationship between attachment, mentalizing, emotion regulation and quality of life among adolescents between 14 and 18 years of age.

In our non-clinical cross-sectional research, 141 adolescents filled out the Experiences in Close Relationships questionnaire, the Difficulties in Emotion Regulation Scale, the Reflective Functioning Questionnaire and the Quality of Life Scale after informed consent. We tested two mediator models, in which emotion regulation and mentalizing were the mediating variables in the relationship between attachment difficulty and quality of life.

In our analyses, attachment difficulties (c’ = -1,87, p < .001, β = -0.41) and emotion regulation problems (b = -0.08, p < .001, β = -0.39) also predicted a reduced quality of life. Attachment problems also reduce the quality of life of young people through emotional regulation difficulties (∑ab = -0,81 [-1,21 – -0,45], β = -0.17). However, mentalizing was not significantly related to the adolescents’ quality of life (b = -0,05, p = .10, β = -0,11). Mentalizing also did not mediate the relationship between attachment and quality of life (∑ab = -0.09 [-0.27 – -0.02], β = -0.02).

Our results suggest that adolescents’ emotion regulation has a prominent role in their quality of life in addition to attachment styles. To improve the quality of life among adolescents, we recommend using techniques that develop emotion regulation.

In clinical practice, significant delays in requesting help are observed in patients with depressive symptoms and suicidal ideation.

The objective of this study was to determine factors associated with the time of untreated illness in a population with depressive disorder attending mental health for the first time in the area of Hospital Clínico Universitario de Valladolid (HCUV).

Methods: This is an observational study including adult patients of both sexes, referred to their first mental health consultation from their Primary Care Physician, with a picture of depressive symptomatology associated with an identifiable stressor. Informed consent was obtained from the patients and authorized by the Ethics Committee of the HCUV. R Studio ® statistical analysis.

The degree of emotional confusion was quantified with item 1 (“I am often confused about the emotions I feel”) of the Toronto Alexithymia Scale (TAS). This item is scored ( 1-5 )from most severe (1) to least (5). On the other hand, the time in weeks between symptom onset to referral, age and symptom severity according to the Montgomery Scale (MADRS) were recorded.

Results: We present data collected in an initial sample of 278 treated patients, with a female predominance (68%), a MADRS severity score (18.05 ± 5.01) and a calculated time without treatment of 59.66 ± 62.26 weeks (Tables 1,2,3).

A subsample of 72 patients with death ideation was studied, with a female predominance (75%) compared to the overall sample (X2 =1.99, p = 0.1585) (Table 4).

It was also observed that death ideation was higher in younger patients (t = 3.18, p = 0.001907) and with a severe MADRS depression score (t = -7.92, p < 0.0001), however they took a similar length of time to receive mental health treatment (T student t = -1.6605, p = 0.099); (Table 5).

There is no previous published evidence that considers the timing of untreated symptoms. According to test statistics, there are differences in untreated symptom time considering gender and TAS score (Table 6).

Death ideation is a current health problem that deserves attention. In multivariate analysis models, an association with clinical and demographic factors has been found; however, there is up to 20% of the variation in prevalence that is not explained by the aforementioned factors. The factors that determine the time delay in seeking help (treatment delays) have not been studied so far.

In this study we observe how a single variable doesn’t explain the delay in the first visit. The interaction between age, gender, alexithymia and hypoprosexia explains the delay in seeking help, although symptom severity doesn’t seem to be related. These data suggest that unexplained causality in multivariate studies may be related to the interaction between clinical and neuropsychological factors.

What is the psychiatrist’s role on a burning planet? As our world faces the existential ramifications of irreversible climate change, clinicians are contending with what purpose a normalizing institution like psychiatry can have in increasingly abnormal times.

This presentation investigates the role of the modern mental health clinician by examining psychiatry’s current impotence in the face of climate crisis. It will be shown that current approaches are often complicit in psychiatry’s historical depoliticization of mental health and subsequent individualization of social concerns. It will be argued that the only way psychiatry can maintain its ethical obligations to its patients is by taking a courageous sociopolitical stance.

Emerging from a multidisciplinary literature review on the relationship between psychiatry and social crises, this work examines our field’s response to climate change in particular. A focus is made on literature that explores psychiatry’s political obligations, current trends in climate psychiatry, and proposed social psychiatric approaches to the climate crisis.

It is shown that while ecological collapse tangibly affects our patients, psychiatry often fails to engage socio-politically with the crisis’ root causes. Framing intense reactions to climate change as trauma responses and developing neo-diagnoses such as “ecoanxiety” both risk individualizing inherently social experiences. However, Psychiatrists are also uniquely positioned to speak with authority about social crises and to articulate what a more comprehensive medical response to climate change might look like.

Given climate change’s disproportionate effects on disenfranchised populations, it is increasingly clear that health is inextricable from social circumstances. As a result, political inaction is incompatible with our ethical duty to serve patients’ health, both in the clinic and beyond it.

There’s large heterogeneity present in major depressive disorder (MDD) and controversial evidence on alterations of brain functional connectivity (FC), making it hard to elucidate the neurobiological basis of MDD. Subtyping is one promising solution to characterize this heterogeneity.

To identify neurophysiological subtypes of MDD based on FC derived from resting-state functional magnetic resonance imaging using large multisite data and investigate the differences in genetic mechanisms and neurotransmitter basis of FC alterations, and the differences of FC-related cognition between each subtype.

Consensus clustering of FC patterns was applied to a population of 829 MDD patients from REST-Meta-MDD database after data cleaning and image quality control. Gene transcriptomic data derived from Allen Human Brain Atlas and neurotransmitter receptor/transporter density data acquired by using neuromap toolbox were used to characterize the molecular mechanism underlying each FC-based subtype by identifying the gene set and neurotransmitters/transporters showing high spatial similarity with the profiles of FC alterations between each subtype and 770 healthy controls. The FC-related cognition in each subtype was also selected by lasso regression.

Two stable neurophysiological MDD subtypes were found and labeled as hypoconnectivity (n=527) and hyperconnectivity (n=299) characterized by the FC differences in each subtype relative to controls, respectively. The two subtypes did not differ in age, sex, and scores of Hamilton Depression/Anxiety Scale.

The genes related to FC alterations were enriched in ion transmembrane transport, synaptic transmission/organization, axon development, and regulation of neurotransmitter level for both subtypes, but specifically enriched in glial cell differentiation for hypoconnectivity subtype, while enriched in regulation of presynaptic membrane and regulation of neuron differentiation for hyperconnectivity subtype.

FC alterations were associated with the density of 5-HT2a receptor in both subtypes. For hyperconnectivity subtype, FC alterations were also correlated with the density of norepinephrine transporter, glutamate receptor, GABA receptor, 5-HT1b receptor, and cannabinoid receptor.

Both subtypes showed correlations between FC and categorization, motor inhibition, and localization. The FC in hypoconnectivity subtype correlated with response inhibition, selective attention, face recognition, sleep, empathy, expertise, uncertainty, and anticipation, while that was related to inference, speech perception, and reward anticipation in hyperconnectivity subtype.

Our findings suggested the presence of two neuroimaging subtypes of MDD characterized by hypo or hyper-connectivity. The two subtypes had both shared and distinct genetic mechanisms, neurotransmitter receptor/transporter profiles, and cognition types.

Major depressive disorder (MDD) is a common multifactorial disorder, but the exact pathophysiology is still unknown. in vivo and post-mortem studies document volumetric and cellular changes in the hippocampus of depressed patients. Chemical synapses are key functional units of the central nervous system and earlier studies found reduced number of synapses in the prefrontal cortex of depressed patients (Kang HJ et al. Nature Medicine 2012;18(9):1413-1417). Mitochondria are intracellular powerhouses generating chemical energy for cellular biochemical reactions. Recent findings suggest that individuals with impaired mitochondrial function may be vulnerable to develop psychopathologies.

We investigated synapses and mitochondria in post-mortem hippocampal samples from psychiatric patients.

The three study groups were: 1) MDD patients (n=11); 2) patients with alcohol dependence (n=8) and 3) controls (n=10). Controls were individuals who accidentally deceased and had no neuropsychiatric disorders. Three sub-regions of the hippocampus (dentate gyrus, CA3 and CA1 areas were investigated. Ultrathin sections were examined, and photomicrographs were taken for further analysis using a JEOL JEM 1400 FLASH transmission electron microscope. Systematic quantitative analysis was conducted with the Neurolucida system using unbiased counting principles.

We could not detect any differences in synapse and mitochondria densities between the patients and controls subjects.

Our preliminary data suggest that despite our expectations hippocampal synapse and mitochondrial densities are rather constant parameters which are not easily affected by psychopathology or alcohol consumption. Potential methodical limitations may also explain this negative finding.
