The OMFIT STEP (Meneghini et al., Nucl. Fusion, vol. 10, 2020, p. 1088) workflow has been used to develop inductive and steady-state H-mode core plasma scenario use cases for a $B_0 = 8 \, {\rm T}$, $R_0 = 4 \, {\rm m}$ machine to help guide and inform future higher-fidelity studies of core transport and confinement in compact tokamak reactors. Both use cases are designed to produce 200 MW or more of net electric power in an up-down symmetric plasma with minor radius $a = 1.4 \, {\rm m}$, elongation $\kappa = 2.0$, triangularity $\delta = 0.5$ and effective charge $Z_{{\rm eff}} \simeq 2$. Additional considerations based on the need for compatibility of the core with reactor-relevant power exhaust solutions and external actuators were used to guide and constrain the use case development. An extensive characterization of core transport in both scenarios is presented, the most important feature of which is the extreme sensitivity of the results to the quantitative stiffness level of the transport model used as well as the predicted critical gradients. This sensitivity is shown to arise from different levels of transport stiffness exhibited by the models, combined with the gyroBohm-normalized fluxes of the predictions being an order of magnitude larger than other H-mode plasmas. Additionally, it is shown that although heating in both plasmas is predominantly to the electrons and collisionality is low, the plasmas remain sufficiently well coupled for the ions to carry a significant fraction of the thermal transport. As neoclassical transport is negligible in these conditions, this situation inherently requires long-wavelength ion gyroradius-scale turbulence to be the dominant transport mechanism in both plasmas. These results are combined with other basic considerations to propose a simple heuristic model of transport in reactor-relevant plasmas, along with simple metrics to quantify coupling and core transport properties across burning and non-burning plasmas.

Introduction
S100B is a calcium-binding astrocyte-specific cytokine, that is considered a biomarker of neurodegeneration; which may be involved in the imbalance of the inflammatory response observed in several brain disorders, including major depression and schizophrenia. Two meta-analyses have reported higher serum levels of S100B in patients with schizophrenia respect to healthy controls.
Different studies have described circadian and seasonal variations of biological variables, such as melatonin or cortisol. It has been reported that there is not circadian rhythm of S100B blood levels in healthy subjects. However, it is not known whether there are circadian oscillations in S100B blood concentrations in patients with schizophrenia.
ObjectivesThe aim of this study is to describe S100B serum levels in patients with schizophrenia and to analyse whether they follow a circadian rhythm.
MethodsOur sample consists in 47 patients in acute phase and stabilized status. Blood samples were collected at 12:00 and 00:00 hours by venipuncture. Serum levels of Protein S100B were measured three times: at admission, discharge and three months after discharge. Protein S100B was measured by means of ELISA (Enzyme-linked immunosorbent assay) techniques.
Results12:00 24:00 P ADMISSION 132,95±199,27 85,85±121,44 0,004 DISCHARGE 73,65±71,744 75,80±123,628 0,070 CONTROL 43,49±34,60 40,14±23,08 0,47 P global P Admission Vs. Discharge P Admission Vs. Control P Discharge Vs. Control 0,97 There is a significance difference between 12:00 and 24:00 at admission for the Protein S100B.However, these difference did not occur at discharge and at three months after discharge.It can be interpreted as there is a circadian rhythm of Protein S100B when the patient has got a psychotic outbreak and disappears at discharge and when is psychopathologically stable.
ConclusionsWith respect to our results we can hypothesize that schizophrenic patients in acute relapse present circadian S100B rhythm that is not present when the patients are clinically stable.Furthermore, the decrease of serum protein S100B levels at discharge is indicative of a reduction of the cerebral inflammation, thus it can be a biomarker of cerebral inflammation and this reduction can be the effect of the treatment. Finally, its circadianity could be a guide of this process and clinical improvement.

Introduction
HIV infection presents complications that may include neuropsychiatric symptoms and whose management is important to avoid misdiagnosis and mistreatment.
ObjectivesThis case aims to highlight the importance of assessing HIV comorbidity in patients with psychiatric onset pathology.
MethodsCase report and literature review.
ResultsWe present the case of a patient diagnosed with HIV in 1985, who after 20 years of disease with irregular adherence begins to present delusional ideation of harm and self-referential, control experiences, thought diffusion phenomena, and possible auditory hallucinations, with poor evolution despite the establishment of numerous antipsychotic treatments, which evolves over the years towards a confabulatory character and with progressive neuropsychological deterioration. After numerous admissions, and despite several treatments, the patient developed over time memory failures, bradypsychia, gait disturbances, and difficulties in self-care, which further aggravated his condition by hindering therapeutic adherence, which ended with the patient’s chronic institutionalization. Diagnosis was AIDS dementia complex.
ConclusionsHIV hardly replicates in the central nervous system but generates antigenemia which, in turn, generates an inflammatory infiltrate that can cause diffuse involvement, predominantly subcortical and limbic system. Usually, the dementia-AIDS picture is insidious and develops in patients with poor control of the primary disease. It is recommended to optimize antiretroviral therapy and neuroprotective agents, as well as symptomatic treatment by psychiatry.

Introduction
Four cases are presented who debut with depressive episodes and after close follow-up, are diagnosed and treated for Alzheimer’s disease
ObjectivesThe aim of this case series is to give a brief review of the depressive prodrome of dementia.
MethodsFour women, aged 67-77 years, treated on an outpatient basis, consulted for depressive symptoms. In addition to affective symptoms such as apathy, lack of interest, sadness, increased emotional lability and anhedonia, all three reported cognitive impairment. In their follow-up after two years, they became progressively more dependent on their partners, with more memory lapses, forgetfulness and progressive loss of higher cognitive functions. With the progression of cognitive impairment, anxious symptoms have become increasingly present.
ResultsThe mean age of the patients is 70 years. Two of them had an insidious onset of depressive symptoms, while the other two had a psychotic onset of depression. None of the patients had no previous history of depression. All four were started on antidepressant treatment with little response. Following the diagnosis of cognitive impairment, treatment was started with rivastigmine, with an adequate response.
ConclusionsDementia and depression are very common in the elderly. It appears that up to 40% of patients with dementia have depressive symptoms. It appears that depression in old age may actually be a prodromal symptom of dementia.

Introduction
Approximately one person commits suicide every 40 seconds, resulting in more than 800,000 deaths per year worldwide. Regarding this phenomenon, it is necessary to highlight how suicide rates increase markedly with age. These reach their highest figures in people aged 85 years or older, and this increase is very worrying in certain geographical areas. Although there is extensive literature on the risk factors that influence at the individual level, the same cannot be said when the problem is analyzed at the population level.
ObjectivesThe study aims to review the entire Eurostat database, relating suicide data from different European countries to any possible variables that may influence suicide. In this pilot phase, certain socioeconomic variables were chosen based on criteria of suitability and availability of the information provided, selecting data from 2015, as it was the most recent year in which most countries reported their data on suicide in people over 85 years of age.
MethodsFirstly, a comparison was made of suicide rates in people over 85 years of age in relation to overall suicide rates in different European countries (suicide rate in people over 85 years of age divided by the total rate in the country). Secondly, socioeconomic variables that may be more strongly related to suicide in this age group in these European countries were studied. After calculating the conditional suicide rate in people over 85 years of age with respect to the overall suicide rate in each country (Fig. 1), Spearman correlations were performed between the conditional rates and different demographic variables, economic variables, social variables, and health variables.
ResultsConditional suicide rates in people over 85 years of age show a marked difference between southern and northern European countries. In the correlational analysis, several significant associations were found. Suicide in those over 85 years of age was associated with economic variables (social deprivation, economic impossibility to buy new clothes, impossibility to dedicate money for personal matters and Gini coefficient), demographic (old-age dependency ratio) and health (self-perceived health). After performing a multivariate regression with the variables that were significant in the Spearman correlation, included the variables “old-age dependency ratio (X1)” and “economic impossibility to buy new clothes (X2),” with a value of R-square = 0.612 and a value of p < 0.01.
Image:
ConclusionsThe conclusions suggest that of the different variables studied, the great majority in which an association has been found belong to the field of economics, specifically poverty and economic inequality, and demographics, highlighting the old-age dependency ratio. Furthermore, marked north/south differences can be observed in the different European countries.

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
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
Negative symptoms has been classically associated with cognition, psychosocial functioning and quality of life in patients with schizophrenia. But negative symptoms are not a unitary construct, encompassing two different factors: diminished expression, and motivation and pleasure. Few works have studied the relationship between these two different negative symptoms factors and cognition (neuro and social cognition), psychosocial functioning and quality of life, jointly, in patients with a first psychotic episode of schizophrenia.
ObjectivesThe objective of the present work was to study, in a sample of patients with a first psychotic episode of schizophrenia, the relationship between the negative symptoms (diminished expression and motivation and pleasure) and neurocognition, social cognition, functioning and quality of life.
MethodsThe study was carried out with 82 outpatients with a first psychotic episode of schizophrenia from two Spanish hospitals (“12 de Octubre” University Hospital, Madrid and “Virgen de la Luz” Hospital, Cuenca). The patients were assessed with the Clinical Assessment Interview for Negative Symptoms (CAINS) for evaluating diminished expression (EXP) and motivation and pleasure (MAP) symptoms, the MATRICS Consensus Cognitive Battery (MCCB) for evaluating neurocognition and social cognition, the Social and Occupational Functioning Assessment Scale (SOFAS), and the Quality of Life Scale (QLS).
ResultsA negative correlation was found between neurocognition and the two negative symptoms subscales: CAINS-EXP (r=-0.458, p<0.001) and CAINS-MAP (r=-0.374, p<0.001); but with social cognition only CAINS-EXP was correlated (r=-0.236, p=0.033). Also, it was found a high negative correlation between SOFAS scores and CAINS-MAP (r=-0.717, p<0.001); and a medium negative correlation with CAINS-EXP (r=-0.394, p<0.001). Finally, QLS score was high correlated with both CAINS subscales: CAINS-EXP (r=-0.681, p<0.001) and CAINS-MAP (r=-0.770, p<0.001).
ConclusionsThis study found a relationship between negative symptoms and neurocognition, social cognition, functioning and quality of life in a sample of patients with a first psychotic episode of schizophrenia. But the two different negative symptom factors, diminished expression, and motivation and pleasure, are associated differently with psychosocial functioning, but especially with social cognition where the relationship was only found with diminished expression symptoms.

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
We present the case of a 49-year-old woman who was diagnosed with multiple sclerosis at the age of 19 and suffers from an affective disorder that has been evolving for years. This condition, for which she has been followed by psychiatry and psychology for more than ten years, consists of alternating periods of hypomania lasting weeks and phases in which frank depressive symptomatology predominates, with no phases of euthymia in between and with a predominance of severe deterioration of her functionality at both poles.
Objectives(1) We will review the term cyclothymia and explore the concept of “cyclothymic temperament” advocated by some authors, in order to be able to understand the dimension of the present case and reformulate its approach.
(2) The relationship between multiple sclerosis and bipolar spectrum disorders will be covered, reviewing the current knowledge in this regard and relating it to the patient’s symptomatology.
MethodsA review of the patient’s clinical history will be carried out, taking into account her life history, the complementary tests performed as well as the multiple therapeutic approaches tried over the last few years.
Likewise, a bibliographic review of the available scientific literature will be carried out in relation to the diagnosis of cyclothymia or bipolar disorder type II, the controversial term “cyclothymic temperament”, and the relationship that these diagnoses have with the diagnosis of Multiple Sclerosis.
Results(1) Our patient could fit into what many authors define as a cyclothymic temperament, fulfilling, in certain episodes, the criteria that the manuals propose for bipolar disorder type II.
(2) 2.1 The prevalence of bipolar affective disorder in MS is approximately twice as high as in the general population (rates of 0.3-2.4%). 2.2 Patients with MS have higher scores in cyclothymic and hyperthymic temperament than the control group. 2.3 Certain drugs generally used in BD also seem to have a beneficial effect on MS.

ConclusionsThe reformulation of the concept of cyclothymia would allow us to recognize in our patient a basic temperament of long evolution that would be the substrate on which different factors have subsequently influenced, such as antidepressant drugs or multiple sclerosis. In addition, it is necessary to know the association between BD and MS, in order to be able to offer an adequate treatment, contemplating some pharmacological options such as Lithium or some Atypical Antipsychotics, given the beneficial effect both for the affective disorder and for the neurological process.

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
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
Interconsultation with the psychiatry service is frequently requested from other specialties for the assessment and treatment of patients who present neuropsychiatric symptoms secondary to organic alterations. On the other hand (and in relation to this case), within the possible causes for the elevation of calcaemia figures, the most frequent are hyperparathyroidism and neoplasms, representing between these two entities 90% of cases (1).
Among the organic mental disorders, Delirium stands out, with an approximate prevalence between 1 and 2% (general population), which increases in hospitalized and elderly patients (2).
ObjectivesPresentation of a clinical case about a patient with delirium secondary to hypercalcemia, with hallucinations and behavioral disturbance.
MethodsBibliographic review including the latest articles in Pubmed about delirium (causes and treatment) and hypercalcaemia secondary to neoplasms.
ResultsWe present a 52-year-old male patient, who went to the emergency room accompanied by his wife, due to behavioral alteration. Two days before, he had been evaluated by Neurology, after a first epileptic crisis (with no previous history) that resolved spontaneously. At that time, it was decided not to start antiepileptic treatment.
The patient reported that he had left his house at midnight, looking for a cat. As he explained, this cat had appeared in his house and had left his entire bed full of insects. His wife denied that this had really happened, and when she told the patient to go to the emergency room, he had become very upset.
As background, the patient used to consume alcohol regularly, so the first hypothesis was that this was a withdrawal syndrome. However, although the consumption was daily, in recent months it was not very high, and at that time no other symptoms compatible with alcohol withdrawal were observed (tremor, tachycardia, sweating, hypertension…).
We requested a general blood test and a brain scan. The only relevant finding was hypercalcaemia 12.9mg/dL (which could also be the origin of the previous seizure). It was decided to start treatment with Diazepam and Tiapride in the emergency room, with serum perfusion, and keep under observation. After several hours, the patient felt better, the hallucinations disappeared, and calcium had dropped to 10.2mg/dL. A preferential consultation was scheduled, due to suspicion that the hypercalcaemia could be secondary to a tumor process.
Image:
ConclusionsIt is important to rule out an organic alteration in those patients who present acute psychiatric symptoms. Hypercalcaemia is frequently associated with tumor processes (1) due to secretion of PTH-like peptide (4), so a complete study should be carried out in these cases.
Delirium has a prevalence between 1 and 2% in the general population (2).
Psychopharmacological treatment is used symptomatically, with antipsychotics (3). For the episode to fully resolve, the underlying cause must be treated.

Introduction
Both in consultations with the general practitioner and with the psychiatrist, antidepressants are one of the most used drugs (1). These have multiple indications, and there are different groups according to their mechanism of action. In relation to this case, we are going to talk about Venlafaxine, a dual-type antidepressant, that is, it inhibits the reuptake of serotonin and norepinephrine. One of the most common side effects is digestive discomfort, which usually resolves after a few weeks (2). However, we should not ignore these symptoms, since they can hide something more serious.
ObjectivesPresentation of a clinical case on a patient who presented an increase in pancreatic amylase after starting treatment with Venlafaxine.
MethodsBibliographic review including the latest articles in Pubmed on side effects of antidepressant treatment, and more specifically at the gastrointestinal level (in this case we will talk about pancreatitis).
ResultsWe present the case of a 49-year-old woman, who was hospitalized 2 years ago, due to a first depressive episode. During this admission, psychopharmacological treatment was started for the first time, on that occasion with a selective serotonin reuptake inhibitor (SSRI), treatment of first choice (3). The patient had no side effects at that time, but the response was very modest, so it was decided to replace that antidepressant with Venlafaxine (with dual action), up to 150mg. The depressive symptoms improved markedly, however the patient began to feel digestive discomfort (which at first did not seem to be of great importance). A general analysis was performed, in which an increase in lipase (978 U/L) and amylase (528 U/L) was detected. An echoendoscopy, an abdominal scan, and a magnetic resonance cholangiography were performed; Pancreatitis secondary to drugs was suspected (a severe condition). Luckily, no significant lesions were found in the tests, and the levels of amylase and lipase decreased when Venlafaxine treatment was withdrawn (without reaching the normal range). The patient was discharged and continued to attend consultations. In the last control, amylase had dropped to 225 U/L. His abdominal pain disappeared. Treatment with Vortioxetine (a multimodal antidepressant) was started, however the amylase levels continue to be monitored, and the patient continues to see the gastroenterologist.
ConclusionsGastrointestinal side effects are very common when taking antidepressant treatment, and in most cases they do not usually represent a serious problem.
However, it is described in the scientific literature that in some cases, acute pancreatitis secondary to some drugs, including Venlafaxine, can occur (4). In order to detect it, it is necessary to perform a blood test and sometimes also other complementary tests.
For its treatment, the fundamental thing is to withdraw the causing drug, trying to find other alternatives, and carry out a control to monitor possible complications

Introduction
Suicidal behaviour and cognition: A systematic review with special focus on prefrontal deficits Introduction: Suicide is a major health concern worldwide, thus, identifying risk factors would enable a more comprehensive understanding and prevention of this behaviour. Neuropsychological alterations could lead to difficulties in interpreting and managing life events resulting in a higher risk of suicide.
ObjectivesObjective: Bibliographic review about the influence of neuropsychological deficits on suicidal behaviour.
MethodsMethod: A systematic literature search from 2000 to 2020 was performed in Medline (Pubmed), Web of Science, SciELO Citation Index, PsycInfo, PsycArticles and Cochrane Library databases regarding studies comparing cognition of attempters versus non-attempters that share same psychiatric diagnosis. Results: 1.885 patients diagnosed with an Affective Disorder (n = 1512) and Schizophrenia/ Schizoaffective Disorder (n = 373) were included.
ResultsIn general comparison, attention was found to be clearly dysfunctional. Regarding diagnosis, patients with Schizophrenia and previous history of suicidal behaviour showed a poorer performance in executive function. Patients with current symptoms of an Affective Disorder and a previous history of suicidal attempt had poorer performance in attention and executive function. Similarly, euthymic affective patients with history of suicidal behaviour had worse decision-making, attention and executive function performance compared to euthymic non-attempters.
ConclusionsPatients who have attempted suicide have a poorer neuropsychological functioning than non-attempters with a similar psychiatric disorder in attention and executive function. These alterations increase vulnerability for suicide.

Introduction
Relapse prevention is a key objetive for patients with a First Episode Psychosis (FEP) and the low adherence to antipsychotic (AP) treatment is the main reason for relapse after a FEP.
ObjectivesThere are no clear recommendations about the early use of long-acting injectables (LAIs) in FEP. We review the impact on hospitalization rates of the early use (earlier than 1 year after the inclusion in our Early Intervention Service “Lehenak”) of LAI paliperidone in a FEP sample.
MethodsWe evaluated in a naturalistic study a sample (N=384) of patients with a FEP. We carried out a mirror-design study to compare the numer of hospitalizations before and after the introduction of LAI paliperidone (1 and 3 monthly) in early users (<1 year) vs late users (>1 year).
ResultsA total of 384 FEP patients with LAI paliperidone were assessed.
Early Paliperidone LAI (n=201) Late Paliperidone LAI (n=173) Within groups comparisons t (p) Hospitalizations pre-LAI mirror period (media, standard deviation) 1.76 (1.97) 2.22 (2.60) 1,87 (0.06) Days in hospital pre-LAI mirror period 21.42 (28.28) 28.02 (38.27) 1.87 (0.06) Hospitalizations post-LAI mirror period 0.68 (1.61) 0.80 (1.74) 0.73 (0.46) Days in hospital post-LAI mirror period 15.17 (40.58) 18.78 (45.24) 0.81 (0.42) ConclusionsThere was no difference between the early and late introduction of LAI Paliperidone in the number of hospitalizations after treatament. There was a trend to present more previous hospitalizations and days in hospital in late users. This could support an earlier use of paliperidone LAI to prevent an excess of hospitalizations due to late introduction.

Introduction
Chronic pain has an impact that goes beyond the physical plane and, over the years, it ends up deteriorating the emotional, working and social life of people who suffer it.
ObjectivesSince we are working with patients who suffer a chronic pathology that cannot be cured, the objective of the group is to create a safe space in which these patients can feel understood, facilitating emotional expression and promoting an active attitude. Accepting pain and its limitations allows the person to regain their ordinary life.
MethodsA multicomponent group therapy with a cognitive-behavioural orientation was carried out. The group was formed by 12 patients, all of them women with chronic pain. Eleven sessions were established on a weekly basis of one and a half hours of duration.
ResultsIn each session a specific aspect was worked on, favouring the learning of techniques, tools and strategies of coping. A global approach was made, including behavioural, cognitive and emotional elements. At the end of the process, the patients reported benefits in their ability to manage anxiety and depression symptomatology, and they reflected a lower impact of pain in their daily life.
ConclusionsGiven the complexity of the symptomatology in chronic pain, it is important to approach the treatment from a multidimensional perspective that envisages every component of pain in order to being able to give a response to the physical and psychosocial impact that it implies, favouring a better confrontation and adaptation.
