Energy drinks can cause cardiovascular, gastrointestinal, and other health disorders. These effects are particularly pronounced in youth. The aim of this study was to systematically review the literature on the consumption of energy drinks in European countries.

A systematic bibliographic search was performed in November 2024 in EMBASE, MEDLINE (Ovid), Scopus and Cochrane databases with no restrictions on country, study period, study design and language.

Energy drinks are beverages high in caffeine, sugar, and other stimulants.

A total of 2008 studies were identified and reviewed by four researchers. Ninety-four met the inclusion criteria and were extracted in a table designed ad hoc.

The included studies showed differences regarding their design, definition of consumption, and time frame under study. The most studied frequency of energy drink consumption was weekly consumption, and the most studied population was school students. An increase in prevalence of consumption was observed when tracking energy drink consumption over time. Variables most related to consumption were low socioeconomic status, alcohol and tobacco consumption, physical activity, age, and sex.

It is difficult to have a clear picture of the extent of energy drink consumption in Europe, mainly due to differences in the design of the studies and the lack of periodicity of the estimates in different countries. However, given the health problems that have been associated with energy drink consumption, regulation of these beverages is essential, especially in youth.

Children who have undergone an oncological process and have received treatment with chemotherapy or radiotherapy on the central nervous system may have significant neurocognitive sequelae. Some video games have shown neurocognitive benefits in people with impairments in different areas, such as attention or memory.

This work aims to demonstrate the benefit of a video game-based training program to improve the neurocognitive profile in a child survivor of cancer.

The patient is a 9-year-old female who was diagnosed with acute lymphoblastic leukemia at the age of 4 years. She received routine treatment of this disease by chemotherapy, including high-dose chemotherapy (with blood-brain barrier crossing) and intrathecal chemotherapy. She is currently 3 years after the end of treatment.

The Continuous Performance Test 3 (CPT-3) (sustained attention/vigilance) was administered before and after a multifaceted training program consisting of playing 3 video games for 12 weeks, as follows: a brain-training game (4 days per week, 7-12 minutes per day), a skill-training game (2 days per week, 10 minutes per day) and an exergaming game (2 days per week, 10 minutes per day).

Prior to intervention, the patient had 3 atypical z-scores on the CPT-3 (z scores: mean = 0, S.D. = 1), with a pattern compatible with ADHD (omissions z = 1.2; hit reaction time z = 3.4; hit reaction time block change z = 1.2). After intervention, she had only an atypical z-score (hit reaction time z = 3.6), with a pattern compatible with slowing, without ADHD.

The neuropsychological evaluation of this patient showed an improvement in his attentional pattern on the CPT-3 after the video game-based training.

Childhood cancer survivors have neurocognitive sequelae that in most survivor follow-up programs are underdiagnosed and for which there is usually no treatment plan.

Video games have demonstrated various psychological and neurocognitive benefits in different subpopulations, such as patients with organic neurological deficits or children with ADHD. However, few studies have been carried out using video games-based interventions in the paediatric oncology population.

The aim of this work is to present the WINNERS study protocol, the objectives of which are to diagnose the neurological and cognitive sequelae in child cancer survivors, and to demonstrate the benefit in these areas of a training program based on video games.

A randomized controlled and unblinded trial is presented. Fifty-six patients aged 8 to 17 years stratified into two age groups (8-12 and 13-17) who had received any of the following treatments 1 to 6 years before the enrolment will be selected: high-dose chemotherapy with blood-brain barrier crossing, intrathecal or intraventricular chemotherapy, CNS radiotherapy or hematopoietic stem cell transplantation.

A neuropsychological evaluation will be performed consisting of a battery of neuropsychological tests to assess parameters such as attention, memory, visuospatial ability or speed of response, as well as a neuroimaging evaluation by structural and functional magnetic resonance imaging. The evaluation will be repeated 3 months and 6 months after the enrolment. Patients will be randomized to a treatment group or to a recycled waiting group. Intervention will consist on a 12-week training at home using 3 video games: a brain training game, an exergaming game and a skill training game.

According to the hypotheses of this study, it is expected that the proposed program of videogame-based interventions will improve neurocognitive and other wellbeing parameters in the intervention group.

This study aims to improve the quality of care for patients who have survived a cancer disease by detecting sequelae that have so far been poorly attended, and by proposing a gamification-based intervention program that is effective and attractive for this population.

Women experiencing severe perinatal mental health problems require specialized services and care. Perinatal mental disorders are common and can contribute to maternal mortality, affecting neonatal, infant, and child outcomes. Home treatment can prevent hospital admissions and promote strategies within the patient’s support network.

Our aim is to describe a clinical case in perinatal psychiatry managed by a Psychiatric Home Treatment Unit.

We present a case of perinatal psychotic depression in a 26-year-old pregnant woman.

We describe the case of a patient with no prior history of mental health issues. She was 25 weeks pregnant when she first sought psychiatric help in July 2023 and was diagnosed with depressive disorder with psychotic symptoms. She reported symptoms such as low mood, psychomotor inhibition, delusional guilt thoughts, and auditory hallucinations beginning three weeks before her initial visit. Due to her clinical presentation, the patient was admitted to the hospital, where pharmacological treatment was initiated with Olanzapine 5 mg, Sertraline 50 mg, and Lorazepam 1.5 mg. She remained in the hospital for four days, during which she showed gradual improvement but did not achieve full recovery.

Considering the improvement observed, home treatment was proposed and accepted by the patient and her relatives. During home treatment, she continued to exhibit persistent depressive and psychotic symptoms, including low mood, inhibition, and delusional thoughts of ruin and catastrophe. Therefore, her treatment was adjusted, with Olanzapine increased to 10 mg, Sertraline raised to 100 mg, and Lorazepam reduced to 0.75 mg. Over time, significant improvement in her clinical symptoms was noted. Throughout the follow-up period, she reported no significant side effects from the pharmacological treatment. After a month of follow-up in our department, she was discharged with outpatient care provided by a specialized community perinatal psychiatric unit.

We illustrate the possibility of home treatment for perinatal psychiatric disorders. The potential benefits of remaining close to one’s support network and developing coping strategies can be advantageous during the course of illness. Further studies should be conducted to explore these potential benefits.

Paediatric cancer survivors have a risk for neuropsychological impairment due to the disease and the treatment received. These affections have been neglected in the follow-up of these patients. It is important to identify the most valid outcomes in the evaluation of neurocognitive sequelae in childhood cancer survivors.

This work aims to compare the results obtained between subjective perception of caregivers and objective cognitive performance based on validated attention tests.

In a randomized controlled and unblinded trial to demonstrate the benefit of video games on different neurocognitive areas in cancer survivors, we studied attention functioning before and after the intervention program. The attention deficit subscale from the Behavior Assessment System for Children 3rd edition (BASC-3), self- and parent-reported versions, and the Continuous Performance Test, 3rd edition (CPT 3) will be used as outcomes (z scores: mean = 0, S.D. = 1).

We observed an improvement in attention after intervention using the CPT-3 (omissions z = 1.2; hit reaction time z = 3.4; hit reaction time block change z = 1.2 versus hit reaction time z = 3.6 without other atipycal z scores after intervention), changing the attentional pattern from “ADHD” to “slowed”. However, in the parent-reported version of the BASC-3, a worsening in the attention subscale is observed (z = 0.3 pre-intervention vs z = 1.0 post-intervention) while the self-reported version of the patient didn’t show any significant changes (z = 1.4 pre-intervention vs z = 1.1 post-intervention).

It is essential to use objective tests to measure neurocognitive sequelae in these patients. Subjective surveys can provide additional information, but not substitute the above.

To investigate the occurrence of traumatic stress symptoms (TSS) among healthcare workers active during the COVID-19 pandemic and to obtain insight as to which pandemic-related stressful experiences are associated with onset and persistence of traumatic stress.

This is a multicenter prospective cohort study. Spanish healthcare workers (N = 4,809) participated at an initial assessment (i.e., just after the first wave of the Spain COVID-19 pandemic) and at a 4-month follow-up assessment using web-based surveys. Logistic regression investigated associations of 19 pandemic-related stressful experiences across four domains (infection-related, work-related, health-related and financial) with TSS prevalence, incidence and persistence, including simulations of population attributable risk proportions (PARP).

Thirty-day TSS prevalence at T1 was 22.1%. Four-month incidence and persistence were 11.6% and 54.2%, respectively. Auxiliary nurses had highest rates of TSS prevalence (35.1%) and incidence (16.1%). All 19 pandemic-related stressful experiences under study were associated with TSS prevalence or incidence, especially experiences from the domains of health-related (PARP range 88.4–95.6%) and work-related stressful experiences (PARP range 76.8–86.5%). Nine stressful experiences were also associated with TSS persistence, of which having patient(s) in care who died from COVID-19 had the strongest association. This association remained significant after adjusting for co-occurring depression and anxiety.

TSSs among Spanish healthcare workers active during the COVID-19 pandemic are common and associated with various pandemic-related stressful experiences. Future research should investigate if these stressful experiences represent truly traumatic experiences and carry risk for the development of post-traumatic stress disorder.

Transition between adolescence and adulthood represents the most important challenge for personal development and involves several transformations: physical, psychological and social. It is a complex age bracket, concurring the transition from youth psychiatric units to adult ones, with an increased risk for the appearance of mental disorders and risky behaviours. TRANVIA program, developed in Avilés, provides psychiatric assistance to patients between 15 and 25 years old, diagnosed with a severe psychiatric disorder or with an increased risk of having one.

Our objectives are: ensuring clinical continuity assistance, promoting communication among professionals and the empowerment of our patients to improve their functionality and quality of life.

Descriptive study including patients involved in TRANVIA program from November 2019 to November 2021.

During this two-years period there have been 44 referrals to the program, 11 of them were rejected for failure to comply with diagnostic criteria. In November 2021 there were 33 patients included in the TRANVIA program with an average age of 17 years old (range: 15-22). 70% of them were men and 30% women. All of them had psychiatric assistance from different sources: youth mental health units, neuropediatrics… About 75% of the patients were diagnosed with autistic spectrum disorder and approximately three-quarters of the sample needed pharmacological treatment. Risperidone was the most prescribed drug. We have also developed other assistance alternatives as home-based care, relaxation sessions, social worker interventions and coordination with schools.

TRANVIA program has allowed us to provide continual attention to vulnerable patients that shift from youth psychiatric units to adult ones. Patients that meet inclusion criteria were enrolled independently the type of assistance they have previously received. Accessibility and flexibility were our priority. During the described period there was only one dropout, three patients required psychiatric hospitalization and two others visited the emergency department. There have been no cases of completed suicide.

Chronic psychiatric patients admitted to subacute and long-stay hospital units are especially vulnerable to the situation of confinement due to the pandemic. Throughout 2020 and 2021 they have suffered the consequences of multiple strict confinements given the differences in isolation protocols in hospitalized patients compared to the general population. This has repercussions on the increase in anxious symptomatology, which influences a more torpid and prolonged evolution of mental disorders in this subpopulation.

The objective of this study is to study the anxiety levels of patients admitted to a sub-acute and long-stay mental health unit in a situation of confinement due to covid-19.

We have carried out a cross-sectional descriptive observational study in 25 patients admitted to the subacute and long-stay unit of the Barcelona Forum Center between December 8 and 23, 2021 in the context of confinement due to a covid-19 outbreak. Sociodemographic and clinical variables are collected. We have used the self-administered STAI scale to assess clinical anxiety.

The mean age is 47.7 years; women 60%. 80% with single marital status. 90% of the patients presented active tobacco consumption, with an average of 21.2 cigarettes/day. The mean score on the STAI scale was 58.8 for state anxiety and 46.7 for trait anxiety, both levels above the 75th percentile for adults, both men (state anxiety 28, trait anxiety 25) and women (state anxiety 31, trait anxiety 32).

The state and trait anxiety scores of the STAI scale of hospitalized patients are higher than the average of the general population, which could be due to the situation of confinement due to the covid pandemic.

Long-term COVID-19 effects has been recently described as persistent and prolonged symptoms after an acute and severe SARS-COV-2 (1). An important concern is that the sequelae of severe COVID-19 may suppose a substantial outpatient 's burden for the specialized services in reopening pandemic phase (2).

To describe the frequency of mental health service use in COVID-19 hospitalized patients after discharge and to estimate the costs associated to the post- discharge consultations.

We used a 1-year follow-up cohort of 1455 COVID-19 inpatients hospitalized in La Paz University Hospital of Madrid, Spain between March 16th and April 15th, 2020. Data were retrieved from Psychiatry Service (PS) electronic health records and we described the frequency of mental health reason for consultation. We used information published by the Madrid health Office to estimate the cost of initial and following appointments.

Our sample consisted of 1,455 patients admitted with a COVID-19 diagnosis between March 16th and April 15th, 2020, and then discharged. Roughly half of them were men (776, 53%), 238 (16%) had a prior history of mental health problems, and 44 (3%) died. 193 participants (13%) visited the mental health department after being discharged. The total cost was estimated in 103,581 USD, of which two-thirds corresponded to patients with prior history of mental health problems.

Our results indicate that the mental health burden of severe COVID-19 inpatient s after discharge was substantial during the first year of follow-up. This generate important economic impact to mental health providers and society at large.

Longitudinal data on the mental health impact of the coronavirus disease 2019 (Covid-19) pandemic in healthcare workers is limited. We estimated prevalence, incidence and persistence of probable mental disorders in a cohort of Spanish healthcare workers (Covid-19 waves 1 and 2) -and identified associated risk factors.

8996 healthcare workers evaluated on 5 May–7 September 2020 (baseline) were invited to a second web-based survey (October–December 2020). Major depressive disorder (PHQ-8 ≥ 10), generalised anxiety disorder (GAD-7 ≥ 10), panic attacks, post-traumatic stress disorder (PCL-5 ≥ 7), and alcohol use disorder (CAGE-AID ≥ 2) were assessed. Distal (pre-pandemic) and proximal (pandemic) risk factors were included. We estimated the incidence of probable mental disorders (among those without disorders at baseline) and persistence (among those with disorders at baseline). Logistic regression of individual-level [odds ratios (OR)] and population-level (population attributable risk proportions) associations were estimated, adjusting by all distal risk factors, health care centre and time of baseline interview.

4809 healthcare workers participated at four months follow-up (cooperation rate = 65.7%; mean = 120 days s.d. = 22 days from baseline assessment). Follow-up prevalence of any disorder was 41.5%, (v. 45.4% at baseline, p < 0.001); incidence, 19.7% (s.e. = 1.6) and persistence, 67.7% (s.e. = 2.3). Proximal factors showing significant bivariate-adjusted associations with incidence included: work-related factors [prioritising Covid-19 patients (OR = 1.62)], stress factors [personal health-related stress (OR = 1.61)], interpersonal stress (OR = 1.53) and financial factors [significant income loss (OR = 1.37)]. Risk factors associated with persistence were largely similar.

Our study indicates that the prevalence of probable mental disorders among Spanish healthcare workers during the second wave of the Covid-19 pandemic was similarly high to that after the first wave. This was in good part due to the persistence of mental disorders detected at the baseline, but with a relevant incidence of about 1 in 5 of HCWs without mental disorders during the first wave of the Covid-19 pandemic. Health-related factors, work-related factors and interpersonal stress are important risks of persistence of mental disorders and of incidence of mental disorders. Adequately addressing these factors might have prevented a considerable amount of mental health impact of the pandemic among this vulnerable population. Addressing health-related stress, work-related factors and interpersonal stress might reduce the prevalence of these disorders substantially. Study registration number: NCT04556565

Clozapine is the most effective antipsychotic for treatment resistant schizophrenia but adverse reactions to clozapine include neutropenia. Patients with COVID-19 infection frequently experience lymphopenia, but not neutropenia.The impact of clozapine treatment in the presence of COVID-19 is unknown

Show 2 cases of neutropenia in patients treated with long-term clozapine during COVID-19 infection.

Subjects: 48 admitted patients to a long-stay psychiatric unit. COVID-19 infection confirmed by positive nasopharyngeal swab for viral ribonucleic acid of SARS-CoV-2. Hematological controls between March and April 2020.

16 patients (33%) treated with clozapine.18 patients (37’5%) had COVID-19 infection, of which 5 (10’4%) were treated with clozapine; 2 presented neutropenia. 1- 56-year-old woman diagnosed with schizophrenia on clozapine since 2009. Begins to have a dry cough and fever with positive COVID-19 swab (day 0). Slight leukopenia without neutropenia was observed on day 1. On day 7, neutropenia was observed with an absolute neutrophil count (ANC) of 1100. We decided to suspend clozapine and to initiate daily hematological controls. The ANC on day 8 was 970. Over the next few days the ANC will progressively improve until neutropenia resolved (day 22). 2- 55-year-old woman who required a transfer to a general hospital because of respiratory complications from COVID-19. She presented significant leukopenia (1’01x 10^3/uL) and neutropenia (ANC 100). Clozapine was not withdrawn. She was treated with granulocyte colony-stimulating factor.

An urgent full blood count will be required to exclude neutropenia with appropriate action. Further research will be needed to clarify the possible relationship between COVID-19, clozapine and neutropenia.

The Cognitive Disorders Unit carries out sessions of Psychoeducational Groups (PG) for caregivers of patients diagnosed with cognitive impairment (CI). The aim is to educate about the disease, improve the caregiver’s self-care and learn how to take better care of the sick.

Analyze the profile of the caregivers that participate in PG and assess changes in their psychological state.

Subjects: 110 caregivers of patients diagnosed with mild-moderate CI who have participated in PG. Methodology: sociodemographic data of the caregiver and patient are collected. The following scales are passed: General-Health-Questionnaire (GHQ-12), Global-Deterioration-Scale, Barthel-Index. 5 sessions of 90 minutes are carried out every fortnight. An opinion questionnaire and the GHQ-12 are administered at the end of the sessions.

86% of caregivers are women: 37% spouses and 55% daughters; mean age 57; 92% of patients live with the caregiver. 62% of caregivers present some kind of psychological disorder that is significantly reduced (p=0,0003) after some sessions. After PG: 65% of caregivers are able to further enjoy their daily activities 46% improve concentration capacity 42% improve sleeping and mood. Opinion Questionnaire Results: 98% of caregivers are satisfied with the activities, the topics addressed and their applicability.

The participants in PG were mostly daughters of patients, with average age 57, and living in the same household. Participation in PG improves the information and skills of caregivers, and reduces psychological disorders by improving their mood, their ability to concentrate, their quality of sleep and enjoyment of daily activities.

Clozapine is the most effective antipsychotic for treatment resistant schizophrenia. In patients treated with clozapine, COVID-19 infection may result in complications including an increased risk of pneumonia, clozapine toxicity, and disruption to clozapine treatment by COVID-19 induced lymphopenia.

We report 5 cases of elevated clozapine levels occurring in patients with COVID-19 infection who had been previously managed for several years on stable doses.

Subjects: 48 admitted patients to a long-stay psychiatric unit. COVID-19 infection confirmed by positive nasopharyngeal swab for viral ribonucleic acid of SARS-CoV-2. Hematological controls between March and April 2020.

16 patients (33%) treated with clozapine.18 patients (37’5%) had COVID-19 infection, of which 5 (10’4%) were treated with clozapine. Results are presented in table 1. Increases in plasma clozapine levels were observed in all cases (49’38 to 307.5%). We don’t have the clozapine levels of a patient who presented a pneumonia requiring admission and treatment in the general hospital. Two cases of neutropenia were observed, of which one had to discontinue treatment with clozapine. In the other three patients the dose of clozapine was reduced and they did not present haematological or intoxication complications that required further adjustments.

Covid-19 infection is associated with increased serum clozapine levels by probably multifactorial mechanisms (systemic infection, reduced smoking). Importance of full clinical assessment of suspected COVID-19 infection in clozapine treated patients, including assessment clozapine level, and full blood count. The general recommendation is to reduce the dose of clozapine in this patients.

Horticultural therapy is a professional practice that is increasingly used in a lot of mental health rehabilitation programs. This therapy was introduced in the Comunitary Rehabilitation Service of INAD, considering its beneficial results in patients with severe mental disorder in combination with the usual rehabilitation program.

We would like to study the benefits of this therapy compared to the usual in our patients.

This is an explanatory study for the purpose of establishing the association between the application of a Therapeutic Horticulture Program and the Clinical Symptomatology of Schizophrenia. A research with an experimental design Pre and Post-Test was carried out, by applying a Horticulture Program and evaluating with PANSS after 6 months its effects on the Clinical Symptomatology. The participants of the experimental group were selectively chosen. The only selection criteria were to attend the orchard at least once a week and be diagnosed with a schizophrenic disorder. The control group was chosen according to the number of members that made up the other group, with the criterion that they did not perform any outdoor activities and also had a diagnosis of schizophrenia.

The comparison of the Pre and Post-Test measures in the case of the experimental group reports the presence of statistically significant differences in the scale of positive symptomatology composite scale and general scale.

This psychopathological improvement of those participants open a door to possible applications of this therapy as a psychosocial treatment.

Oncologic patients with schizophrenia have a higher mortality, which could be explained by a delayed diagnosis and a poor quality of the oncologic treatment (1). Some of the potential reasons are related with patient’s psychopathology, stigma, and barriers in access to medical care. An structured support during the oncologic treatment has been proposed to solve the difficulties that patients with schizophrenia can experience when handling with an oncologic process. (2).

To illustrate two approaches for cancer accompaniment in patients with schizophrenia.

We present two case-report and literature research of the topic.

Case A. A 49 y.o. woman diagnosed with a schizoaffective disorder. In the last years she had difficulties to manage her selfcare, so her mental health providers linked her to an individualized community nurse, who later played a crucial role in helping the patient during the diagnosis and treatment of a breast cancer. Case B. A 37 y.o. man diagnosed with schizophrenia, who was very integrated in a peer-support organization. After being diagnosed with a Lymphoma, he continued participating in all the group activities (theatre, collaborative radio, painting) until his decease. Sharing the process with other patients not only improved his quality of life but also helped the group to manage the grief.

- Individualized support with a mental health nurse could enhance the communication between the oncologist and mental health providers, improve the symptoms management, and allow psychological support. - Peer-support can prevent social isolation, improve the quality of life and the management of the oncologic treatment.

Cocaine dependence disorder has been widely described. However, differences due to gender remain unknown.

To compare clinical gender differences in a large sample of cocaine-dependent patients.

We performed a cross-sectional, observational study in 902 patients (35.47 yo, 21.3% women) with a cocaine dependence according DSM-IV criteria, seeking treatment during 2005 to 2013. Sociodemographic and clinical variables were collected The SCID-I, SCID–II, BIS and a structured interview about cocaine-induced psychosis were performed. Simple descriptive statistics were carried out for demographic and clinical data. Bivariate analysis was made to compare the main variables by sex using SPSSvs18.0.

No differences in age of dependence onset, other clinical variables or cocaine-induced psychosis were detected. However, less cocaine used in the last month (2.12 vs 3.37g) (p < 0.009), more impulsivity (67.2 vs 63.03) (p < 0.040), and more sedative dependence (21.2% % vs 8.3%)(p< 0.00) were detected in women than in men. Affective disorders lifetime were the most prevalent (57,4%) in women. More comorbidity with anxiety disorders (p< 0.025) eating disorders (p< 0.000) and personality disorders (p< 0.039) were detected in women than in men.

Sedative dependence and anxiety disorders should be investigated in cocaine-dependent women in order to treat these conditions. Surprisingly high impulsivity level was detected and could moderate cocaine consumption. However, no difference have been found previously in studies about gender differences in cocaine-dependent patients, so this finding should be confirm in new studies.

Obesity Unit of Psychiatry Department was created to offer first-class medical treatment to patients with obesity in a district of Madrid (Vallecas) since 2011. The main objective is to obtain diagnostic information about the patients in order to decrease the prevalence of obesity in our community.

We are presenting the data of the 100 first patients referred to our Unit, 5 people were excluded due to exclusion criteria. Sociodemographic and clinical data were obtained from evaluation interviews and were complemented by a battery of psychometric tests.

The average BMI is 41 (SD 6.8). The average age, 41.7 (SD 12.7) and 76 patients were women. 85% of the patients were not able to maintain weight loss. 50% of the patients had consulted a physician before. 95% of patients have taken a pharmacological treatment. No one had followed a combined treatment, addressing physical and emotional aspects together.

A specific multidisciplinary treatment is recommended in these patients. In addition to pharmacological treatment, our integral attention program also includes a psychoeducational group one a month and a psychotherapy group one a week.

Drug use among medical students is partially unknown. However, consumption among medical students may have a similar role if compared with the rest of population.

To study drugs use among medical students comparing gender and evolution on drugs use.

Students enrolled in the fifth year of the medical studies at the Universidad Autónoma de Barcelona, from the course 2008-2009 to 2014-2015, were offered the chance to participate voluntarily in the study.

The students agreed to participate anonymously in a survey filled in during the beginning days of the psychiatry classes. They were asked about their drug consumption, including legal drugs (alcohol and tobacco) and illegal drugs. During the seven study years, 469 questionnaires were collected (74.1% of women) and mean age was 22.77 (20-35) yearsold.

The students reported consuming alcohol (66.7%; 65.5% women, 70.4% men), tobacco (18.6%; 18.1% women, 20% men) and illegal drugs (15.1%; 12.4% women, 22.8% men). The female students consumed fewer illegal drugs than the men (p 0.008) as showed above. Comparing 2008/2009 and 2014/2015 courses, the consumption was: alcohol 75.5% and 65.7%, tobacco 24.5% and 13.2% and illegal drugs 22.4% and 14.7%.

Drug consumption is an important problem among medicalstudents who will becomeprescribing doctors in a few months after the survey. There is a decreased tendency to use illegal drugs. Due to the gender differences on illegal drug use a special focus must be placed on the male group.

Cocaine consumption can induce transient psychotic symptoms. Cocaine induced psychosis (CIP) is common but not developed in all cases. However, prevalence and clinical features are not well known. In psychiatry settings different studies have reported prevalence ranging between 29%–86.5%.There are few samples including more than 150 patients for studding this topic.

The objective of this study is to determinate the CIP prevalence and the most prevalent psychotic symptoms.

We study presence of psychotic symptoms using a clinical interview for psychotic symptoms in a large sample of 287 cocaine-dependent patients.

We study the presence of psychotic symptoms using a clinical interview for psychotic symptoms in a large sample of cocainedependent patients. Patients suffering from schizophrenia or bipolar disorders were excluded. Finally we included 287 patients in the study. (80.8% men and 35.77 yo).

A structured interview were systematically conducted. The Structured Clinical Interview for DSM IV Axis I and Axis II disorders were used in order to identify the comorbidity.

Psychotic symptoms were detected in 59.9% of the sample. The most frequent symptoms reported lifetime was suspiciousness 38.6% and paranoid beliefs 27.2% Auditory hallucinations were reported by 23.6%, visual hallucinations by 13.3%, and kinesthetic hallucinations by 7.8%. Motor alterations were not evaluated.

Our dates confirm previous study. CIP prevalence is high. Motor alterations were not evaluated, so symptoms could be underestimated. Identifying this kind of symptoms can be useful in order to minimize risks of psychotic states for the patients or others.
