OBJECTIVES/GOALS: to investigate the potential impact of grandparental factors and multigenerational epigenetic inheritance on the development of ASD METHODS/STUDY POPULATION: Our study recruited participants from the CHARGE (Child Autism Risks from Genetics and the Environment) study, including grandparents, parents, and children. A questionnaire was used to gather information about the participants’ exposure to environmental factors. Saliva samples werecollected from 349 participants. Newborn dried blood spotsfrom probands and parents are still being collected from the California New born Registry. DNA was extracted from 349 saliva samples from 85 families and subjected to whole genome bisulfite sequencing (WGBS) to analyze DNA methylation. Sequence alignments and bioinformatic analyses will be performed using R packages called DMRichR and Comethyl. RESULTS/ANTICIPATED RESULTS: Sequence alignments and bioinformatic analyses are ongoing, utilizing DMRichR to identify individual genomic loci associated with ASD in each of the three generations and Comethyl to compare correlation patterns between methylation marks and selected variables, including grand parental exposures. New born blood spot collections of parents and probands are ongoing and will be used to identify potential ASD epigenomic signatures that are tissue and life-stage independent. DISCUSSION/SIGNIFICANCE: This research will provide new insights into the increased prevalence and underlying etiology of ASD that should pave the way for future research in the field. DNA Methylation signatures can help create molecular biomarkers which can be used together with behavioral clinical tests for diagnosis of ASD.

Evaporation of multi-component liquid mixtures in confined geometries, such as capillaries, is crucial in applications such as microfluidics, two-phase cooling devices and inkjet printing. Predicting the behaviour of such systems becomes challenging because evaporation triggers complex spatio-temporal changes in the composition of the mixture. These changes in composition, in turn, affect evaporation. In the present work, we study the evaporation of aqueous glycerol solutions contained as a liquid column in a capillary tube. Experiments and direct numerical simulations show three evaporation regimes characterised by different temporal evolutions of the normalised mass transfer rate (or Sherwood number $Sh$), namely $Sh (\tilde{t} ) = 1$, $Sh \sim 1/\sqrt {\tilde{t} }$ and $Sh \sim \exp (-\tilde{t} )$, where $\tilde {t}$ is a normalised time. We present a simplistic analytical model that shows that the evaporation dynamics can be expressed by the classical relation $Sh = \exp ( \tilde{t} )\,\mathrm {erfc} ( \sqrt {\tilde{t} })$. For small and medium $\tilde{t}$, this expression results in the first and second of the three observed scaling regimes, respectively. This analytical model is formulated in the limit of pure diffusion and when the penetration depth $\delta (t)$ of the diffusion front is much smaller than the length $L(t)$ of the liquid column. When $\delta \approx L$, finite-length effects lead to $Sh \sim \exp (-\tilde{t} )$, i.e. the third regime. Finally, we extend our analytical model to incorporate the effect of advection and determine the conditions under which this effect is important. Our results provide fundamental insights into the physics of selective evaporation from a multi-component liquid column.

Objective:
Primary progressive aphasia (PPA) is a dementia syndrome characterized by initial development of progressive language deficits in the absence of impairment in other cognitive domains. It has historically been difficult to assess the presence or nature of true memory deficits in this population due to interference from language disturbance on task performance. The Three Words Three Shapes test (3W3S) is a relatively easy memory task that evaluates both verbal and nonverbal memory within the same modality and assesses different aspects of memory, including incidental encoding, effortful encoding, delayed recall, and recognition. Persons with PPA show a material-specific dissociation in performance on 3W3S; specifically, deficits in incidental encoding and recall are limited to verbal, not nonverbal material, in PPA, with preserved recognition of both types of information. However, it is unknown whether this pattern persists over time as the disease progresses.
Participants and Methods:Participants were 73 participants enrolled in an observational PPA research study at the Mesulam Center for Cognitive Neurology and Alzheimer’s Disease (Mage = 66.75 years, SD = 6.77; Meducation = 16.11 years, SD = 2.38; 51% female). Participants were subtyped as semantic (n = 15), logopenic (n = 27), or agrammatic PPA (n = 31) based on Gorno-Tempini et al., 2011, using 3W3S and other neuropsychological measures as described previously. Participants were followed at 2-year intervals and tests were administered longitudinally. All participants in the current study had 3W3S scores from at least two research visits collected between September 2012 and September 2022.
Results:There were no significant baseline group differences on 3W3S performance, except for better incidental encoding in the logopenic than the semantic group for shapes (p = .040) and words (p = .043). We then conducted a mixed measures ANOVAs to determine baseline within-person comparisons between words vs shapes. Within individuals, performance on incidental encoding, effortful encoding, and recognition was worse for words than shapes (ps < .01). There was an interaction between material and group for delayed recall (p < .001) such that there was a significantly larger discrepancy between word and shape recall in the semantic (Mdiff = -9.14) compared to logopenic (Mdiff = -3.07) and agrammatic groups (Mdiff = -2.13). Repeated measures ANOVAs determined changes in scores over time collapsed across PPA subtypes. Incidental encoding (ps = <.01), effortful encoding (ps < .05), and delayed recall (ps < .01) declined for both words and shapes over time. Copy and recognition of words (ps < .05), but not shapes declined over time.
Conclusions:The current results are consistent with prior findings of relative preservation of memory for nonverbal compared to verbal material in PPA as measured by 3W3S, especially in the semantic subtype. Learning and recall of words and shapes declined over time in all groups, whereas there was selective decline in copy and recognition of words compared to shapes. These results provide evidence of differential patterns of decline in certain aspects of memory over time in PPA and highlight the relative preservation of memory in this language-focused dementia even over time.

Linear stability theory (LST) is often used to model the large-scale flow structures in the turbulent mixing region and near pressure field of high-speed jets. For perfectly expanded single round jets, these models predict the dominance of azimuthal wavenumbers $m=0$ and $m = 1$ helical modes for the lower frequency range, in agreement with empirical data. When LST is applied to twin-jet systems, four solution families appear following the odd/even behaviour of the pressure field about the symmetry planes. The interaction between the unsteady pressure fields of the two jets also results in their coupling. The individual modes of the different solution families no longer correspond to helical motions, but to flapping oscillations of the jet plumes. In the limit of large jet separations, when the jet coupling vanishes, the eigenvalues corresponding to the $m=1$ mode in each family are identical, and a linear combination of them recovers the helical motion. Conversely, as the jet separation decreases, the eigenvalues for the $m=1$ modes of each family diverge, thus favouring a particular flapping oscillation over the others and preventing the appearance of helical motions. The dominant mode of oscillation for a given jet Mach number $M_j$ and temperature ratio $T_R$ depends on the Strouhal number $St$ and jet separation $s$. Increasing both $M_j$ and $T_R$ independently is found to augment the jet coupling and modify the $(St,s)$ map of the preferred oscillation mode. Present results predict the preference of two modes when the jet interaction is relevant, namely varicose and especially sinuous flapping oscillations on the nozzles’ plane.

Objective:
The Cognitive Change Index (CCI-20) is a validated questionnaire that assesses subjective cognitive complaints (SCCs) across memory, language, and executive domains. We aimed to: (a) examine the internal consistency and construct validity of the CCI-20 in patients with movement disorders and (b) learn how the CCI-20 corresponds to objective neuropsychological and mood performance in individuals with Parkinson’s disease (PD) or essential tremor (ET) seeking deep brain stimulation (DBS).
Methods:216 participants (N = 149 PD; N = 67 ET) underwent neuropsychological evaluation and received the CCI-20. The proposed domains of the CCI-20 were examined via confirmatory (CFA) and exploratory (EFA) factor analyses. Hierarchical regressions were used to assess the relationship among subjective cognitive complaints, neuropsychological performance and mood symptoms.
Results:PD and ET groups were similar across neuropsychological, mood, and CCI-20 scores and were combined into one group who was well educated (m = 15.01 ± 2.92), in their mid-60’s (m = 67.72 ± 9.33), predominantly male (63%), and non-Hispanic White (93.6%). Previously proposed 3-domain CCI-20 model failed to achieve adequate fit. Subsequent EFA revealed two CCI-20 factors: memory and non-memory (p < 0.001; CFI = 0.924). Regressions indicated apathy and depressive symptoms were associated with greater memory and total cognitive complaints, while poor executive function and anxiety were associated with more non-memory complaints.
Conclusion:Two distinct dimensions were identified in the CCI-20: memory and non-memory complaints. Non-memory complaints were indicative of worse executive function, consistent with PD and ET cognitive profiles. Mood significantly contributed to all CCI-20 dimensions. Future studies should explore the utility of SCCs in predicting cognitive decline in these populations.

We used a strand-specific RT-qPCR to evaluate viral replication as a surrogate for infectiousness among 242 asymptomatic inpatients with a positive severe acute respiratory coronavirus virus 2 (SARS-CoV-2) admission test. Only 21 patients (9%) had detectable SARS-CoV-2 minus-strand RNA. Because most patients were found to be noninfectious, our findings support the suspension of asymptomatic admission testing.

Background
Women and gender-diverse people with early psychosis are at risk for suboptimal sexual health outcomes, yet little research has explored their sexual health experiences.
AimsThis study explored sexual health experiences and related priorities among women and gender-diverse people with early psychosis, to identify opportunities for improvements in sexual health and well-being.
MethodSemi-structured individual qualitative interviews explored how patient participants (n = 19, aged 18–31 years, cisgender and transgender women and non-binary individuals) receiving clinical care from early psychosis programmes in Ontario, Canada, experienced their sexual health, including sexual function and behaviour. Thematic analysis was conducted, with triangulation from interviews/focus groups with clinicians (n = 36) who provide sexual and mental healthcare for this population.
ResultsThree key themes were identified based on patient interviews: theme 1 was the impact of psychotic illness and its treatments on sexual function and activity, including variable changes in sex drive, attitudes and behaviours during acute psychosis, vulnerability to trauma and medications; theme 2 related to intimacy and sexual relationships in the context of psychosis, with bidirectional effects between relationships and mental health; and theme 3 comprised autonomy, identity and intersectional considerations, including gender, sexuality, culture and religion, which interplay with psychosis and sexual health. Clinicians raised each of these priority areas, but emphasised risk prevention relative to patients’ more holistic view of their sexual health and well-being.
ConclusionsWomen and non-binary people with early psychosis have wide-ranging sexual health priorities, affecting many facets of their lives. Clinical care should incorporate this knowledge to optimise sexual health and well-being in this population.

Introduction
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.
ObjectivesOur objectives are: ensuring clinical continuity assistance, promoting communication among professionals and the empowerment of our patients to improve their functionality and quality of life.
MethodsDescriptive study including patients involved in TRANVIA program from November 2019 to November 2021.
ResultsDuring 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.
ConclusionsTRANVIA 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.

Introduction
It is estimated that the prevalence of severe Intellectual Disability (ID) is 6 per 1,000 people. ID is sometimes the cause of Behavioral Disorders (BD) with aggressive and impulsive behaviors that make family and social life difficult. However, despite its high prevalence, the number of studies on it is very scarce.
When BD appears, it should be evaluated if there is a physical or psychiatric cause that causes it and assess non-pharmacological treatments. If they are insufficient, treatments such as risperidone are used to manage BD. When these are ineffective, the use of drugs with greater difficulties in their effects and clinical management, such as clozapine, is required.
ObjectivesThe objective is to describe the use of clozapine in patients with severe ID associated with BD.
MethodsRetrospective descriptive study. Patients older than 18 years with severe ID and BD, treated with clozapine for at least two years were included. Those with medical or psychiatric comorbidity were excluded.
ResultsThe sample consisted of 12 patients, 16.67% women (n=2) and 83.33% men (n=10), aged 47.57±9.27 years. Prior to the introduction of clozapine, a mean of 2.67±1.21 antipsychotics had been tested. The mean dose of clozapine was 264.24±70.50 mg/day. The patients had received treatment for 51.57±25.67 months, following the usual controls. None had hematological adverse effects or other serious adverse effects.
ConclusionsClozapine can be an effective and safe therapeutic alternative in the treatment of BD in intellectual disabled patients which do not respond to other treatments. The clinical benefits of clozapine treatment seem to outweigh the potential risks associated with the treatment. However, more studies are needed to evaluate the effects of clozapine in patients with intellectual disabilities.

Introduction
Maintenance electroconvulsive therapy (mECT) is an option in the treatment of affective disorders which progress is not satisfactory. It is certainly neglected and underused during the clinical practice.
ObjectivesTo evaluate the efficacy of mECT in reducing recurrence and relapse in recurrent depression within a sample of three patients.
MethodsWe followed up these patients among two years since they received the first set of electroconvulsive sessions. We applied the Beck Depression Inventory (BDI) in the succesives consultations for evaluating the progress.
ResultsThe three patients were diagnosed with Recurrent Depressive Disorder (RDD). One of them is a 60 year old man that received initially a cycle of 12 sessions; since then he received 10 maintenance sessions. Other one is a 70 year old woman that received initially a cycle of 10 sessions; since then she received 6 maintenance sessions. The last one is a 55 year old woman that received initially a cycle of 14 sessions; since then she received 20 maintenance sessions.
All of them showed a significant reduction in depressive symptoms evaluated through BDI and clinical examination. In the first case, we found a reduction in the BDI from the first consultation to the last that goes from 60 to 12 points; in the second case, from 58 to 8 points; and in the last case, from 55 to 10 points. The main sections that improved were emotional, physical and delusional.
As side-effects of the treatment, we found anterograde amnesia, lack of concentration and loss of focus at all of them.
ConclusionsWe find mECT as a very useful treatment for resistant cases of affective disorders like RDD.
It should be considered as a real therapeutic option when the first option drugs have been proved without success.

Introduction
Schizotypal disorder is conceptualized as a stable personality pathology (Cluster A) and as a latent manifestation of schizophrenia. It can be understood as an attenuated form of psychosis or high-risk mental state, which may precede the onset of schizophrenia or represent a more stable form of psychopathology that doesn’t necessarily progress to psychosis.
ObjectivesTo exemplify the continuum of psychosis
MethodsReview of scientific literature based on a relevant clinical case.
Results39-year-old male living with his parents. He started studying philosophy. He is a regular cannabis user and has an aunt with schizophrenia. He’s admitted to psychiatry for behavioral disturbance in public. He refers to having been hearing a beeping noise in his street for months, what he interprets as a possible way of being watched due to his past ideology. Without specifying who and why, he sometimes shouts “until it bursts” to stop the noise and he thinks that his neighbours alerted the police about his behavior. During the interview he alludes to Milgram’s experiment, saying that throughout history there have been crimes against humanity and those who pointed them out were labeled “crazy”. His father refers that he has always been “strange” and with certain extravagant revolutionary ideas and thoughts. He doesn’t maintain social relationships and dedicates himself to reading and writing.
ConclusionsIt’s important to understand psychosis as a continuum to advance the understanding of etiology, pathophysiology and resilience of psychotic disorders and to develop strategies for prevention and early intervention

Introduction
Bipolar disorder (BD) is a serious and chronic mental disease of mood. Lithium is used for treatment and studies have demonstrated that it is the most efficient drug, reducing suicide risk in a high percentage of patients. However, this drug has well known side effects, such as kidney damage. Lithium could cause chronic kidney disease, specially with the presence of other risk factors.
ObjectivesObservational and retrospective study of creatinine levels and glomerular filtration rates observed in blood analysis (follow-up period of 11 years). Sample size of 263 patients diagnosed of BD I and BD II in treatment with lithium. We used socio-demographic (age, sex) and clinic variables (diabetes mellitus, hypertension, use of nonsteroidal anti-inflammatory drugs (NSAIDs) and/or diuretics) to generate bivariate and multivariate analysis.
MethodsOur main objective is to analyze the deterioration of kidney function and the development of chronic kidney disease that chronic treatment with lithium can induce in patients with BD. Our secondary objective is to determine variables which could promote the development of chronic kidney disease, and to assess if these variables could be considered as risk factors during the treatment with lithium.
Results11,3 % of patients in our study developed chronic kidney disease during monitoring. The deterioration of GFR in patients in treatment with lithium was significantly associated with female sex and NSAIDs consumption. A trend towards statistical significance was found regarding the use of diuretics (p=0,060). No statistical significance was found between diabetes mellitus, hypertension or type of BD and the deterioration of kidney function in our sample. An inverse association was found between the GFR decline and the age but no statistical significance was demonstrated.
ConclusionsWe conclude that female sex and use of NSAIDs are predicting factors of GFR decline in patients with BD in chronic treatment with lithium. We must take into account these drugs or even avoid concomitant treatment (lithium and NSAIDs) in order to prevent chronic kidney disease. In addition to it, we should recommend careful use of diuretics during treatment with lithium because of risk of dehydration. Diabetes mellitus and hypertension have universally been associated to increase risk of development of chronic kidney disease. However, we have not found statistical significance in our study. Therefore, research should be done in order to determine specific risk factors in this group of patients and, consequently, optimize their treatment.

Introduction
There is a fine line separating psychiatry and neurology. Most movement disorders can have psychiatric symptoms, not only those caused by the disease itself, but also those induced by the drugs used to treat them.
ObjectivesPresentation of a clinical case about a patient diagnosed with Parkinson’s disease presenting a several-month-long delirious episode due to dopaminergic drugs.
MethodsLiterature review on drug-induced psychosis episodes in Parkinson’s disease.
ResultsA 57-year-old patient with diagnosis of Parkinson’s disease for six years, who went to the emergency room accompanied by his wife due to delirious ideation. He was being treated with levodopa, carbidopa and rasagiline for years, and rotigotine patches whose dosage was being increased over the last few months.
His wife reported celotypical clinical manifestations and multiple interpretations of different circumstances occurring around her. He chased her on the street, had downloaded an app to look for a second cell phone because he believed she was cheating on him, and was obsessed with sex. He had no psychiatric background. It was decided to prescribe quetiapine.
The following day, he returned because he refused to take the medication since he thought he was going to be put to sleep or poisoned. It was decided to admit him to Psychiatry.
During the stay, rasagiline and rotigotine were suspended. Olanzapine and clozapine were introduced, with behavioral improvement and distancing from the psychotic symptoms which motivated the admission. The patient was also motorically stable. Although levodopa is best known for causing psychotic episodes, the symptons were attributed to rotigotine patches for temporally overlapping the dose increase.
ConclusionsPsychiatric symptoms are the third most frequent group of complications in Parkinson’s disease after gastrointestinal complications and abnormal movements. All medication used to control motor disorders can lead to psychosis, not only dopaminergics, but also selegiline, amantadine and anticholinergics.
Excessive stimulation of mesocortical and mesolimbic dopaminergic pathways can lead to psychosis, which is the most common psychiatric problem related to dopaminergic treatment.
In the face of a psychotic episode, antiparkinsonian drugs which are not strictly necessary for motor control should be withdrawn. If this is not sufficient, levodopa dose should be reduced, considering the side effects that may occur. When the adjustment of antiparkinsonian treatment is not effective, neuroleptics, especially quetiapine or clozapine, should be administered. In a recent study, pimavanserin, a serotonin 5-HT2 antagonist, was associated with approximately 35% lower mortality than atypical antipsychotic use during the first 180 days of treatment in community-dwelling patients.
Medication should always be tailor-made to suit each patient and we usually have to resort to lowering or withdrawing the dopaminergic medication.

Introduction
Bipolar disorder comorbidity rates are the highest among the major mental disorders. In addition to other intoxicants, alcohol is the most abused substance because it is socially accepted and can be legally bought and consumed. Estimates are between 40-70% with male predominance, which further influences the severity with a more complicated course of both disorders.
ObjectivesThe objective of this article is to highlight the impact of substance use on the course and prognosis of bipolar disorder, as well as to make a differential diagnosis of a manic episode in this context.
MethodsBibliographic review of scientific literature based on a relevant clinical case.
ResultsWe present the case of a 45-year-old male patient. Single with no children. Unemployed. History of drug use since he was young: alcohol, cannabis and amphetamines. Diagnosed with bipolar disorder in 2012 after a manic episode that required hospital admission. During his evolution he presented two depressive episodes that required psychopharmacological treatment and follow-up by his psychiatrist of reference. Since then, he has been consuming alcohol and amphetamines occasionally, with a gradual increase until it became daily in the last month. He went to the emergency department for psychomotor agitation after being found in the street. He reported feeling threatened by a racial group presenting accelerated speech, insomnia and increased activity.
ConclusionsThe presence of substance abuse complicates the clinical presentation, treatment and development of bipolar disorder. It is associated with a worse prognosis with multiple negative consequences including worsening symptom severity, increased risk of suicide and hospitalization, increased medical morbidity and complication of social problems. In addition, this comorbidity delays both the diagnosis and treatment, by masking the symptoms, and making more difficult an adequate differential diagnosis.

Introduction
In the early stages of schizophrenia the person experiences feelings of strangeness about themselves, difficulty in making sense of things and difficulty in interacting with their environment. Based on this, self-disorder assessment instruments have been developed and empirical studies have been conducted to assess people at risk of developing a schizophrenia spectrum disorder. These studies show that self-disorders are found in pre-psychotic stages and that their manifestation can predict the transition to schizophrenia spectrum disorders.
ObjectivesWe present the case of a patient with multiple diagnoses and mainly dissociative symptoms who, after years of evolution, was diagnosed with schizophrenia.
MethodsBibliographic review including the latest articles in Pubmed about self-disorders and schizophrenia.
ResultsWe present the clinical case of a 51-year-old woman with a long history of follow-up in mental health consultations and with multiple hospital admissions to the psychiatric unit, with several diagnoses including: dissociative disorder, histrionic personality disorder, adaptive disorder unspecified psychotic disorder and, finally, schizophrenia. The patient during the first hospital admissions showed a clinical picture of intense anxiety, disorientation and claiming to be a different person. The patient related these episodes to stressors she had experienced, and they improved markedly after a short period of hospital admission. Later, psychotic symptoms appeared in the form of auditory and visual hallucinations and delusional ideation, mainly of harm, so that after several years of follow-up and study in mental health consultations and in the psychiatric day hospital, she was diagnosed with schizophrenia and treatment with antipsychotics was introduced, with a marked clinical improvement being observed.
ConclusionsIt is important to take into account this type of symptoms (self-disorders), as they allow the identification of individuals in the early stages of the disorder and create the opportunity for early therapeutic interventions.

Introduction
Bipolar Disorder (BD) is considered a serious mental disorder characterized by a changing mood that fluctuates between two completely opposite poles. It causes pathological and recurrent mood swings, alternating periods of exaltation and grandiosity with periods of depression. We talk about rapid cyclers when four or more manic, hypomanic or depressive episodes have occurred within a twelve-month period. Mood swings can appear rapidly. Approximately half of the people with bipolar disorder may develop rapid cycling at some point.
ObjectivesPresentation of a clinical case about a patient with Bipolar Disorder with rapid cycling and poor response to treatment.
MethodsReview of the scientific literature based on a clinical case.
Results33-year-old male, single, living with his mother, under follow-up by mental health team since 2012. First debut of manic episode in 2010. The patient has filed multiple decompensations related to consumption of toxics (alcohol and cannabis). Currently unemployed. He attended to the emergency service in June 2022 accompanied by his mother, who reported that he was restless. The patient refers that he has interrupted the treatment during the vacations, having sleep rhythm disorder with abuse of caffeine drinks. Currently the patient does not recognize any consumption.The patient reports that during the village festivals he felt very energetic, occasionally consuming drinks rich in taurine and sugars, even having conflicts with people of the village. Finally, the patient was stabilized with Lithium 400 mg and Olanzapine. In September, the patient returned to the emergency service on the recommendation of his referral psychiatrist due to therapeutic failure. The only relevant finding we observed in the analytical determinations were low lithium levels (0.4 mEq/L). The transgression of sleep rhythms and the abuse of psychoactive substances required the admission of the patient to optimize the treatment (Clozapine, Lithium, Valproic Acid). At discharge, he is euthymic, has not presented behavioral alterations and is resting well. Finally, it was decided that the patient should go to the Convalescent Center to continue treatment and achieve psychopathological stability.
ConclusionsBipolar disorder is an important mental illness, having an incidence of 1.2%, being responsible for 20% of all mood disorders. Therefore, it is important to perform an adequate and individualized follow-up of each patient. Treatment with mood stabilizers tries to improve and prevent manic and depressive episodes, improving chronicity and trying to make the long-term evolution as good as possible, being important psychoeducation and psychotherapy.

Introduction
Adult ADHD diagnosis sometimes represents a challenge for the clinician, due to the comorbid psychiatric diseases that are often associated and which complicate de recognition of the primary symptoms of ADHD. The prevalence of ADHD in adult populations is 2’5% and it is a relevant cause of functional impairment.
ObjectivesPresentation of a clinical case of a male cocaine user diagnosed with adult ADHD.
MethodsLiterature review on adult ADHD and comorbid substance abuse.
ResultsA 43-year-old male who consulted in the Emergency Department due to auditory hallucinosis in the context of an increase in his daily cocaine use. There were not delusional symptoms associated and judgment of reality was preserved. Treatment with olanzapine was started and the patient was referred for consultation. In psychiatry consultations, he did not refer sensory-perceptual alterations anymore, nor appeared any signals to suspect so, and he was willing to abandon cocaine use after a few appointments. He expressed some work concerns, highlighting that in recent months, in the context of a greater workload, he had been given several traffic tickets for “distractions.” His wife explained that he had always been a inattentive person (he forgets important dates or appointments) and impulsive, sometimes interrupting conversations. In the Barkley Adult ADHD Rating Scale he scored 32 points.
He was diagnosed with adult ADHD and treatment with extended-release methylphenidate was started with good tolerance and evolution, with improvement in adaptation to his job and social environment. Since then, the patient has moderately reduced the consumption of drugs, although he continues to use cocaine very sporadically.
ConclusionsEarly detection of ADHD and its comorbidities has the potential to change the course of the disorder and the morbidity that will occur later in adults. Comorbidity in adult ADHD is rather the norm than the exception, and it renders diagnosis more difficult. The most frequent comorbidities are usually mood disorders, substance use disorders, and personality disorders. Treatment of adult ADHD consists mainly of pharmacotherapy supported by behavioral interventions. When ADHD coexists with another disorder, the one that most compromises functionality will be treated first and they can be treated simultaneously. The individual characteristics of each patient must be taken into account to choose the optimal treatment.

Introduction
Different studies indicate high prevalence’s of suicidal behaviour, anxiety, depression, insomnia, and PTSD associated with the COVID-19 pandemic. There is currently not enough scientific evidence available to analyze the impact that the COVID-19 pandemic has had on the rate of suicide attempts and their characteristics.
ObjectivesTo analyze and compare the characteristics of suicidal behavior (in terms of method, severity, medical damage produced and need for hospitalization) of patients attended during the COVID-19 pandemic compared to previous years.
MethodsA retrospective study was performed based on a standardized data collection of patients attending the University Hospital La Paz between April 2018 and November 2021. 581 patients who attempted suicide at least once were included in this study. We compared the severity using the Beck Suicide Intent Scale. Chi-square ant Student’s t were used to compare clinical characteristics such as medical damage, method of suicide attempt and indication for admission after the attempt, between suicide attempts during the COVID-19 pandemic and previous years.
ResultsOur results suggest that during the COVID-19 pandemic suicide attempts caused more medical damage (p<0.001), had higher severity (p<0.000), and required more admission in Intensive Care Units, General Internal Medicine and Psychiatry compared with pre-Covid years (p<0.000).
ConclusionsThis is the first study in Spain analysing the changes in characteristics of suicide attempts during the COVID-19 pandemic. This has important implications for reducing suicide rates, preventing future attempts, and enabling us to design specific treatments of Suicidal Behaviour.

Introduction
Subjective memory complaints remain a relevant aspect to be considered in patients with mild cognitive impairment. Likewise, their association with depressive symptoms, quality of life and cognitive performance is also an objective to be studied in such patients.
ObjectivesOur clinical case represents just one opportunity to study how memory complaints are related to depressive states and how they affect the quality of life of patients with mild cognitive impairment.
MethodsWe conducted a bibliographical review by searching for articles in Pubmed.
ResultsPERSONAL HISTORY: Male, 73 years old, separated, residing alone in Valladolid. He has home help, a person comes to help him with the household chores. Little social and family circle.
History in Mental HealthHe has a history of an admission in 2013 to this Short Hospitalization Unit for ethanol detoxification. Since then, he has been followed up in the Mental Health Unit. According to the reports, he has been diagnosed with depressive disorder and cluster B personality disorder.
Current psychopharmacological treatment: diazepam, olanzapine, duloxetine 60 mg, quetiapine.
Toxic habits: history of chronic ethanol consumption. Smoker. He denies other toxic habits.
Current EpisodeThe patient presents a worsening of his mood of 15 days of evolution, coinciding with a voluntary decrease of his psychopharmacological treatment that the patient has carried out on his own. He walks with the aid of a crutch. Hypomimic facies. Slowed language, circumstantial, with speech focused on current discomfort.
On assessment, he reports initial improvement after reducing his medication, but in recent days he has experienced a decrease in initiative accompanied by feelings of emptiness, sadness and loneliness. He refers to memory complaints for which he is awaiting evaluation by Neurology. The patient explains that at other times in his life he has presented self-harming ideas that he has been controlling. At this time he expresses desire for improvement and adequate future plans, and accepts plans to attend a memory workshop. He also reports visual hallucinations with no affective repercussions and preserved judgment of reality.
Therapeutic PlanTreatment adjustment: Duloxetine 60 mg, 2cp/day. The patient is recommended to lead an active lifestyle and attend a day center or memory workshop.
ConclusionsIn numerous patients with mild cognitive impairment, we have observed that memory complaints are closely related to depressive symptoms and to the patient’s functioning in daily life.
In one study memory complaints were a negative predictor of quality of life in these patients.
Therefore, in addition to considering the importance of treating depressive symptoms, it is also important to address quality of life in patients with mild cognitive impairment.

Introduction
Reducing maternal and newborn mortality is apriority on the health agenda. Priority, integral, integrated and barrier-free care a attention to the population frames the spirit of the route. The Comprehensive Care Route in Perinatal Maternal Health (CRPMH) proposes “to promote health and the improvement of maternal and perinatal health outcomes, through comprehensive health care, including coordinated action FROM the state, THE society and the family on the social and environmental determinants of health inequities” (Minsalud).
ObjectivesTo evaluate the implementation of the CRPMH in a group of maternal students from 0-12 months.
MethodsQualitative, through semi-structured interview techniques and focused groups (FG) referenced from the CRPMH (table 1) in 11 undergraduate students in psychology over 18 years from 2 Colombian universities.
ResultsQualitative analysis evaluates convergences/divergences by percentages of questionnaire responses and axial text analysis (FG). In preconception attention 100% of mothers do not report signs of health risk, however, caesarean section was performed in 83.3% of cases, this safer method is perceived for the mother and fetus, and is justified taking into account that the pain of childbirth is very strong (FG).
In gestational health they indicate prenatal control, medical appointments, formation in the condition of the fetus, guidelines on care, respectful upbringing and breastfeeding in 100%. In contrast, the focus group reports low empathy of doctors toward levels their fears, reduced time to address concerns, negative information about labor and satisfaction with medical procedures, considering caesarean section a humanized strategy.
Access to CRPMH is known by 50% of mothers, they do not know the preconceptional consultation. In the GF they conclude that the information on preparation for maternity and paternity is ineffective.
Psychological support is absent during childbirth and postpartum. There is a greater knowledge about breastfeeding 83.3%
DiscussionThe successful implementation of the route could reduce the risks of physical and psychological impact on perinatal maternal health by facilitating decisions about motherhood and its practice in the university educational environment. There was recognition of the clinical factors of the CRPMH and ignorance of the responsibility of the educational environment in its implementation.

ConclusionsThe CCRPMH regulation is insufficient to guarantee its implementation. Risk factors include the quality of service provided by health-care providers and the lack of knowledge of regulations in university management.
