To assign far infrared (FIR) absorption bands of K+ in muscovite, dichroic experiments were performed. For a muscovite crystal rotated about a crystallographic axis, c*, a, or b, two bands corresponding to vibration modes of K+ appear, respectively, at 107 and 110 cm−1 (rotation about c*), 107 and 143 cm−1 (rotation about a), and 110 and 143 cm−1 (rotation about b). Two in-plane modes at 107 and 110 cm−1 and one out-of-plane mode at 143 cm−1 are identified for the vibrations of K+ in muscovite. Each of these transition moments are near the crystallographic axes b, a, and c, respectively. These observations match well predictions based on the approximate C3i symmetric environment of K+, although the site symmetry in the space group of muscovite is only C2.

Objective:
INDUCT (Interdisciplinary Network for Dementia Using Current Technology), and DISTINCT (Dementia Inter-sectorial strategy for training and innovation network for current technology) are two Marie Sklodowska-Curie funded International Training Networks that aimed to develop a multi-disciplinary, inter-sectorial educational research framework for Europe to improve technology and care for people with dementia, and to provide the evidence to show how technology can improve the lives of people with dementia.
Methods:In INDUCT (2016-2020) 15 Early Stage Researchers worked on projects in the areas of Technology to support everyday life; technology to promote meaningful activities; and healthcare technology. In DISTINCT (2019-2023) 15 Early Stage Researchers worked on technology to promote Social health in three domains: fulfilling ones potential and obligations in society, managing one’s own life, and participation in social and other meaningful activities.
Both networks adopted three transversal objectives: 1) To determine practical, cognitive and social factors needed to make technology more useable for people with dementia; 2) To evaluate the effectiveness of specific contemporary technology; 3) To trace facilitators and barriers for implementation of technology in dementia care.
Results:The main recommendations resulting from all research projects are integrated in a web-based digital Best Practice Guidance on Human Interaction with Technology in Dementia which was recently updated (Dec 2022 and June 2023) and will be presented at the congress. The recommendations are meant for different target groups, i.e. people in different stages of dementia, their (in)formal carers, policy makers, designers and researchers, who can easily find the recommendations relevant to them in the Best Practice Guidance by means of a digital selection tool.
Conclusions:The INDUCT/DISTINCT Best Practice Guidance informs on how to improve the development, usage, impact and implementation of technology for people with dementia in various technology areas. This Best Practice Guidance is the result of intensive collaborative partnership of INDUCT and DISTINCT with academic and non-academic partners as well as the involvement of representatives of the different target groups throughout the projects.

Some aspects of the crystal structure of illite are not understood properly yet, in spite of its abundance and significance as a component of soils, sediments, and low-grade metamorphic rocks. The present study aimed to explore the role of hydronium cations in the interlayer space of illite in a theoreticalexperimental approach in order to clarify previous controversial reports. The infrared spectroscopy of this mineral has been studied experimentally and by means of atomistic calculations at the quantum mechanical level. The tetrahedral charge is critical for the stability of the hydronium cations, the presence of which has probably been underestimated in previous studies. In the present study, computational studies have shown that the hydronium cations in aqueous solutions are likely to be intercalated in the interlayer space of illite, exchanging for K cations. During the drying process these cations are stabilized by hydrogen bonds in the interlayer space of illite.

The structure of trimethylsulfoxonium-exchanged vermiculite has been examined to compare it with other onium-exchanged structures, such as tetramethylammonium- and tetramethylphosphonium-exchanged vermiculite. The three organic cations are tetrahedral in shape, but trimethylsulfoxonium [(CH3)3SO+] has an oxygen atom replacing a methyl group at one apex. This study describes the effect this substitution and the larger S atom have on the site location in the interlayer and the effect on the vermiculite 2:1 layer. These clay minerals may be commercially useful as adsorbents.
Na-exchanged crystals of vermiculite from Santa Olalla, Spain, were intercalated with trimethylsulfoxonium [Me3SO+ = (CH3)3SO+] molecules by refluxing in an aqueous 0.25 M trimethylsulfoxonium iodide solution at 80°C for 14 days. The resulting Me3SO+-exchanged vermiculite crystals were studied by single-crystal, X-ray diffraction methods and by computer modeling (density functional theory). Cell parameters are a = 5.349(2), b = 9.270(3), c = 13.825(8) Å, and β = 97.40(4)°, the space group is C2/m, and the polytype is 1M. Refinement results (R = 0.073, wR = 0.080) show that in the average structure of C2/m, the S atoms of the Me3SO+ molecules form two partially occupied planes [2.066(2) Å from each basal oxygen plane] between the 2:1 layers, and the S atoms show considerable positional disorder. The O atom of the Me3SO+ molecule occurs in the central plane of the interlayer, as far away from each 2:1 layer as possible. In projection down the c* axis, the Me3SO+ molecule resides within the center of the silicate rings from each adjacent 2:1 layer. In the ideal (static) model of the Me3SO+-exchanged vermiculite structure, the Me3SO+ molecule is oriented such that two methyl groups point toward charge-deficient bridging oxygen atoms of the basal plane; thus, the organic pillars charge compensate the bridging oxygen atoms of the 2:1 layer that are charge deficient. In projection, the oxygen atom of the Me3SO+ molecule projects over a tetrahedron containing Si. Computer modeling showed that if H2O is not included in the model, the Me3SO+ molecule (S and O atoms) is in the center of the interlayer, but with the addition of randomly placed H2O, two partially occupied planes similar to the X-ray derived model are formed.

The order-disorder behavior of the isomorphous cation substitution of the octahedral sheet of phyllosilicates was investigated by Monte Carlo simulations based only on atomistic models in some three-species systems Al/Fe/Mg including a wide range of different octahedral compositions that can be relevant to clay compositions found in nature, especially for smectites and illites. In many cases, phase transitions do not occur, in that long-range order is not attained, but most systems exhibit short-range order at low temperature. The ordering of the octahedral cations is highly dependent on the cation composition. Variations in the tetrahedral charge (smectite vs. illite) produce slight differences in the cation distribution and the short-range and long-range order of octahedral cations do not change drastically. The average size of Fe clusters and the long-range order of Fe are not larger in illites than in smectites as previous reports concluded, but the proportion of Fe3+ cations non-clustered is higher in smectites than in illites. This behavior supports the experimental behavior of the Fe effect on the Al-NMR signal, which is lower in illites than in smectites.

Objective:
Traumatic brain injury (TBI), very common in the United States (US) and occurring at highest rates in older adulthood, is a documented risk factor for cognitive impairment and dementia. However, the full scope of the problem is unknown, as comparative incidence of TBI among older adults is poorly characterized. Moreover, the effect of demographics (race/ethnicity, sex) and cognitive and medical status, as well as education, socioeconomic status, and other social determinants of health (SDOH) on TBI risk is not well understood. We aimed to explore the impact of demographics, cognitive and medical status, and SDOH on vulnerability to new TBIs among older adults.
Participants and Methods:Enrollees 65 and older in the nationally representative Health and Retirement Study (HRS) who consented to have their survey data linked to Medicare claims and had not experienced a head injury prior to HRS enrollment were studied. We used claims data 2000-2018 to obtain incident TBI diagnoses and harnessed the detailed demographic, cognitive, medical, and SDOH information available in the HRS. Incident TBI was defined using inpatient and outpatient International Classification of Disease (ICD 9 and 10) codes received the same day as an emergency room (ER) visit code and a computed tomography (CT) scan code, occurring after the enrollee’s baseline HRS interview. We calculated descriptive statistics and bivariate associations for TBI status with demographic and SDOH characteristics measured at baseline using sample weights to account for the complex survey design.
Results:Of respondents meeting inclusion criteria (n=9273) during the study follow-up period of 18 years, 8.9% received emergency room treatment for a TBI. Older adults who experienced TBI during the study period were more likely to be female (p=0.0006), and white (p=0.0001), to have normal cognition (vs. cognitive impairment or dementia, p=0.0011), higher education (p<0.0001), and higher income (p=0.01). Having lung disease (p=0.0003) or functional impairment (p=0.03) at baseline were protective against experiencing a TBI.
Conclusions:Our results suggest that almost 9% of US older adults received ER treatment for a new TBI during the 18-year study period, and that race, sex, and SDOH factors may increase risk for, or be protective against, TBI. This novel investigation into the impact of demographics and SDOH on incident TBI suggests access to care may impact who gets treatment for TBI. Further study is indicated and may lead to opportunities for both targeted intervention (e.g., primary TBI prevention) to groups most at risk as well as identification and mollification of the most relevant structural and contextual factors (e.g., access to care) to reduce risk of TBI among older adults.

As mental health issues continue to rise in Latin America, the need for research in this field becomes increasingly pressing. This study aimed to explore the perceived barriers and resources for research and publications among psychiatrists and psychiatry trainees from nine Spanish-speaking countries in South America. Data was collected through an anonymous online survey and analyzed using descriptive methods and the SPSS Statistical package. In total, 214 responses were analyzed. Among the participating psychiatrists, 61.8% reported having led a research project and 74.7% of them reported having led an academic publication. As for the psychiatry trainees, 26% reported having conducted research and 41.5% reported having published or attempted to publish an academic paper. When available, having access to research training, protected research time and mentorship opportunities were significant resources for research. Further support is needed in terms of funding, training, protected research time and mentorship opportunities. However, despite their efforts to participate in the global mental health discussion, Latin American psychiatrists and psychiatry trainees remain largely underrepresented in the literature.

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
Eating disorders (ED) historically been adressed as illnesses that only affect young adolescent females. ED’s in males have been documented in literature as early as the 1960’s; yet men continue to be under represented on research on the topic. For decades, the Diagnostic and Statistical Manual of Mental Disorders (DSM) perpetuated the invisibility of males by including amenorrhea as a diagnostic criterion. It was not until 2013 that male inclusion was endorsed thorught the removal of that criterion. It is estimated that one in four people affected with and ED is male.
It is estimated that one in four people affected with and ED is male. The proportion of males reporting lifetime prevalence of Binge eating disorder (BED) was far greater than for Anorexia nervosa (AN) or Bulimia nervosa (BN); the female versus male ratio of BED prevalence was 3:1. AN is the most life-threatening ED, but is least frequently seen in male populations; researchers suggest this is because most men are not interested in the emaciated, thin look.
ObjectivesThis poster aims to recognize the presence of ED’s in males and raise awareness on this topic.
MethodsCase report and literature review
ResultsWe present the case of a 50-year-old man with long-standing AN, who had never undergone mental health follow-up. He is referred to psychiatrist by his primary care provider (PCP) due to depressive symptoms. His medical history included vitamine D insufficiency and osteoporosis. At the age of 19 he was obese (BMI 35) and from the age of 23 he started to present dietary restriction after a social event. He had never self-induced vomiting, use of laxatives, binge eating or compulsive exercise. He reported no history or current substance use disorder. BMI at first consultation was 17,6 and showed fear of weight gain. Antidepressant therapy was started and patient was referred to a specialized therapist, nutritionistand nurse.
ConclusionsOverall, the findings demand clinicians develop awareness about ED in males to advance illness management and enhance long-term prognosis. In our case, the delay in receiving treatment has probably led to greater morbidity and chronicity. PCP’s play a key role in detection of ED’s as the often act as a first point of contact for men accesing the health care system. While assesing and ED, the PCP should include general questions on eating habits in their intake interview. Once an a ED is suspected, the first few minutes of the encounter are crucial to gain trust and buy-in from the patient. Once buy-in from the patient is gained, a complete physical exam and diagnostic work-up is required. Priority referrals to the following professionals are critical: psychiatrist, therapist, dietician or nutritionist, and ED specialist if available.

Introduction
The elderly represents the fastest growing group of the population. It is fair to assume that the portion of old age patients suffering from bipolar disorder will grow in a similar manner. Elderly patients represent approximately 25% of the bipolar population. Summarizing, 5–10% of patients were 50 years of age when they experienced their first manic episode, constituting the subgroup of late onset bipolar disorder (LOBD).
ObjectivesThe purpose of this case report and literature review is to emphasise the importance of LOBD in old population and to highlight its still sparse-knowledge.
MethodsDescriptive case study and review of literature (Arnold,I. et al. Old Age Bipolar Disorder—Epidemiology, Aetiology and Treatment. Medicina 2021,57,587; Baldessarini et al. Onset-age of bipolar disorders at six international sites. J Affect Disord 2010;121(1-2):143-6).
ResultsA 60-year-old woman is brought to the emergency department for evaluation by her family. Over the past 7 days, the patient has become increasingly irritable and argumentative, is sleeping less, is talking faster than usual and has begun to express paranoid concerns about her students “stealing my exam”. The patient is a university professor.
In the assessment interview she is hyperverbal, expansive, and grandiose. The family has also just recently discovered that she has spent a large sum of money on the Internet.
She has no history of psychiatric contact or substance use disorders; however, she has a family history of severe depression.
In the absence of any plausible non-psychiatric condition that could mimic or induce mania, the working diagnosis is bipolar I disorder, most recent episode (MRE) manic with psychotic features.

ConclusionsThe share of older age bipolar disorder will grow constantly in the next decades and further research on this neglected patient group is urgently required.

Introduction
Women with bipolar disorder often ask their treating clinician for information about family planning, as they are concerned about the impact of their illness on offspring. Pregnancy places additional stress on patients, and physiological changes are particularly acute during postpartum. On the other hand, the risk of abnormalities and teratogenicity from psychotropic drugs is significant. The decision wether resuming or discontinuating lithium is discussed.
ObjectivesWe present a theoretical review on the topic.
MethodsA bibliographic review is presented.
ResultsThe choice to continue medication during pregnancy balances the risks of an untreated illness with the risks of medication exposure. Abrupt discontinuation of psychotropic medications is associated with an increased risk for illness recurrence. Women with BD who discontinue their medications before or during pregnancy have a 71% risk of recurrence with new episodes occurring most frequently in the first trimester. Recurrent illness during pregnancy is associated with a 66% increase in the risk of postpartum episodes. Untreated or under-treated BD during pregnancy is associated with poor birth outcomes independent of pharmacotherapy exposure, including preterm birth, low birth-weight, intrauterine growth retardation, small for gestational age, fetal distress, and adverse neurodeve- lopmental outcomes. Women with untreated BD also have behavioral risk factors such as decreased compliance with prenatal care, poor nutrition, and high-risk behaviors. Impaired capacity to function may result in loss of employment, health care benefits, and social support. The biological and psychosocial risks of a BD episode are the justification for the risk of medication exposure.
Fetal exposure to lithium has been associated with an increased risk for cardiac abnormalities. The risk for Ebstein’s anomaly with first trimester exposure is 1 (0.1%) to 2 in 1000 (0.2%), but the absolute risk remains low. Folate supplementation with 5 mg reduces the risk and severity of congenital heart disease. Lithium toxicity causes lethargy, hypotonia, tachycardia, coma, cyanosis, and chronic twitching in the newborn.
Strategies to minimize fetal exposure and maintain efficacy include using the lowest effective dose, prescribing lithium twice daily to avoid high peak serum concentrations, and regular monitoring of lithium serum concentrations. The effective serum concentration must be established before pregnancy. If a therapeutic concentration has not been established, the lithium dose is titrated to a concentration within the therapeutic range. Breast feeding is discouraged in women taking lithium because of the high rate of transmission to the infant.
ConclusionsTreatment decisions for pregnant women with mood disorders must weigh the potential for increased risks of lithium during pregnancy, especially during the first trimester, against its effectiveness at reducing relapse.

Introduction
The occurrence of psychotic symptoms induced by dopaminergic drugs marks a new phase in the course of Parkinson’s disease (PD). The term drug induced psychosis may be used when other significant psychiatric diseases are excluded in patients with no history of psychosis. The prevalence of dopaminomimetic psychosis varies from 5% to 20%. Therefore, knowledge of the psychopharmacological management of this condition is essential.
ObjectivesThe purpose of this case report and literature review is to to learn the psychopharmacological management of this not uncommon medical complication.
MethodsDescriptive case study and review of literature
ResultsWe present the case of a 71-year-old man with a medical history of Parkinson’s disease with partial response to treatment with high doses of levodopa and carbidopa.
He was brought to the emergency department by his family due to the presence of behavioural alterations at home.
The patient reported seeing men in foam trying to harm his family. In a disjointed way in his speech, he links this idea with the delusional belief that he is being watched by electronic devices placed throughout the house. In a variegated manner he links this with a coelotypical type of discourse, however the delusional ideation remains unstructured throughout.
With no previous personal or family history of mental health and ruling out underlying organic conditions, a diagnosis of psychosis secondary to pharmacological treatment for Parkinson’s disease is presumed.
Considering the risks and benefits, it was decided to maintain the anti-Parkinson’s dose in order to avoid worsening the patient’s motor function. Therefore, after reviewing the literature, the best option was to introduce clozapine at low doses, up to 50 mg at night, with the respective analytical control. After a week’s admission, the patient began to improve psychopathologically, achieving an ad integrum resolution of the psychotic symptoms.
ConclusionsDespite the availability of other antipsychotic treatments such as quetiapine or the more recent pimavanserin, clozapine remains the treatment of choice for drug-induced psychosis in Parkinson’s disease.

Introduction
The Positive and Negative Syndrome Scale for Schizophrenia Autism Severity Scale (PAUSS) scale can be derived from the Positive and Negative Schizophrenia Syndrome Scale, enabling an assessment of psychotic and autistic dimensions with a single tool.
ObjectivesThe aim of the study was to investigate the prevalence of autistic traits and the diagnostic, developmental, clinical, and functional correlates of this phenotype in a sample of early-onset psychosis (onset before age 18 years; EOP).
MethodsProspective observational 2 year- follow-up study in a sample of young people with a first-episode of EOP. Demographic, perinatal, developmental, cognitive, clinical, and functional data were collected. PAUSS total scores and socio-communication and repetitive behaviors subscores were calculated. We used the proposed cut-off points for adult populations to define prevalence of autistic traits (PAUSS≥30). Subgroups of patients with and without autistic traits were identified based on the total PAUSS terciles. We used the Cronbach’s alpha test to assess the PAUSS internal consistency. Linear mixed models were performed to compare changes in PAUSS during follow-up between diagnostic subgroups [i.e., non-affective psychosis (including schizophrenia and schizophreniform disorder), affective psychosis (including bipolar disorder, schizoaffective disorder and major depressive disorder with psychotic features), and other psychosis (including brief psychotic disorder and psychosis not otherwise specified)]. Developmental, clinical, and functional variables were compared between subgroups with and without autistic traits with logistic regression analysis.
Results248 patients with PIT were included (age 15.69 ± 1.86 years, 38.65% female). The prevalence of autistic traits in EOP was 7.04%, with significantly higher prevalence in the group of patients with non-affective psychosis (15.20%) than in other diagnostic groups. PAUSS scores significantly decreased over time, with no significant differences in the trajectories of the total PAUSS and its subscores among the three diagnostic subgroups during the 2-year follow-up. The PAUSS showed good internal consistency at all visits (Cronbach’s alpha > 0,88). Patients with autistic traits presented longer duration of untreated psychosis, longer duration of the first inpatient admission, poorer social adjustment in childhood, poorer functionality, greater clinical severity, and poorer response to treatment during follow-up than patients without autistic traits.
ConclusionsThe PAUSS is an easy-to-apply tool that can be useful to differentiate psychosis subgroups with worse prognosis.

Abstract
Bullying constitutes a major public health concern, on account of its high prevalence rates and its association with a wide range of adverse health outcomes across the lifespan, including increased incidence of mental disorders such as depression, anxiety, and psychotic disorders. Previous research suggests effectiveness of school-based programmes in reducing bullying prevalence and improving mental health outcomes in children and adolescents. Despite the fact that some subpopulations such as young people with special educational needs are at increased risk for both bullying victimisation and mental health difficulties, there is little information on the effectiveness of universal school-based programmes in these high-risk populations. We will review available evidence of the effectiveness of school-based anti-bullying interventions as a tool to improve youth mental health, including results from a cluster-randomised clinical trial conducted in 20 publicly funded schools in Madrid to test the effectiveness of a 12-week web-enabled, user-friendly, school-based, preventive programme incorporating universal and targeted components (LINKlusive; ISRCTN15719015) and discuss the potential implications, challenges, and unmet needs of such approaches.

Introduction
The first definition of PAS, enunciated by Richard Gardner in 1985, refers to a disorder originating in the context of legal conflicts related to child custody. Its main characteristic would be a smear campaign by the child towards a parent, in the absence of plausible arguments. In this context, the child would experience an oppositional and dichotomous feeling towards his or her parents. In recent years, the presence of PAS has become increasingly important, both in the legal and health fields, largely due to the controversy and debate surrounding its approval and recognition, and there is currently no consensus on the matter.
ObjectivesThe main objective of this work is to examine the current state of PAS in depth in the different fields in which it is emerging: the medical-scientific and legal spheres. The current controversies and debate, both scientific and legal, will be developed. Research will be carried out on the origin of the concept and its evolution, its symptomatic presentation, the neuropsychological consequences in minors, the role and legal value of expert reports, as well as the existing evaluation methods for the assessment of PAS.
MethodsAn extensive literature review was carried out on the subject in question, extracting information mainly from scientific articles, but also from legislative documents, manuals and books.
ResultsThere are currently no specific laws regulating PAS in European countries. According to Article 10.2 of the Spanish Constitution, norms related to fundamental rights shall be interpreted according to the Universal Declaration of Human Rights. As a direct consequence of the chronic psychological stresses experienced by children, adaptive disorders may appear, often characterised by symptoms of anxiety and depression. In addition, a multitude of neuropsychological consequences have been observed not only in the affected child, but also in the adult he or she will become.
ConclusionsCurrently, there is a fervent debate about the validity and recognition of PAS as a diagnostic entity, spanning different disciplines, ranging from health to social and legal. In Europe, professionals in the scientific field have not reached an agreement regarding the approval of PAS. On the one hand, there are those for whom PAS is a verified phenomenon; on the other hand, there are those who flatly reject the existence of this phenomenon. The latter consider PAS an unscientific construct, referring to it as “court syndrome” or “patriarchal alienation syndrome”.

Introduction
Denial of pregnancy is the phenomenon where a woman fails to recognize or accept her pregnancy at >20 weeks gestational age. It associates with increased morbidity and mortality of mother and child, and can be classified as non-psychotic or psychotic. There is fewer medical literature regarding the latter, making it difficult to recognize, let alone to treat, since we do not have robust data regarding incidence nor approved interventions or treatment.
ObjectivesTo describe this unfamiliar entity in order to be able to perform a proper diagnosis and thus prevent possible negative outcomes.
MethodsWe present a case report alongside a narrative literature review on the topic.
ResultsWe report the case of a 39-year-old caucasian woman, foreign, undomiciled, with an advanced pregnancy, who was admitted to a Psychiatry in-patient unit due to psychotic symptoms such as mistrust and delusions. She showed scarce collaboration during assessment and did not give any plausible information about her identity. Her birthplace and prior medical records were therefore unknown. Apparently, she had no family nor social support network. Despite the obvious signs, she did not recognize being pregnant and showed great irritability when asked; her responses ranged from claiming she was suffering from a gastric tumor and making delusional attributions of symptoms clearly related to the pregnancy to partially acknowledging her state but refusing to answer any questions on the matter. Blood work showed no significant abnormalities and obstetric ultrasound revealed a low risk 35 weeks pregnancy.
With an estimated prevalence of 1:475 in general population, denial of pregnancy is not as rare as it may seem. The psychotic variant, however, is rather uncommon. Typically, women with psychotic pregnancy denial have prior history of major mental illness, most frequently schizophrenia, and suffer from extreme psychosocial vulnerability. They usually present previous or anticipated child custody loss, which hampers the process of developing antenatal attachment behaviours. Psychotic denial does not associate with concealing, since these women are mentally detached from the gestation and tend to create delusional explanations to their pregnancy symptoms. Not all of them show complete denial, some being able to acknowledge it, though mostly in an inconsistent way. These patients often fail to seek prenatal care or are noncompliant, they are at greater risk of drug exposure, and some are unable to recognize symptoms of labour, all of which increases the rate of negative outcomes for mother and baby, including neonaticide.
ConclusionsPsychotic denial is a rare diagnosis which should be properly assessed due to its clinical implications and the need to prevent potential negative outcomes for mother and baby.

Introduction
Anorexia nervosa is a behavioral mental disorder, characterized by body dysmorphia, an intense fear of gaining weight and behaviors that interfere with this, in addition to a restriction of food intake, associated usually with medical complications, even a considerable risk of death.
Several psychotherapeutic approaches have been used along last decades. Until relatively recently, parents have been recognized as part of the problem, but nowadays we involve them into the therapeutic process through family therapy based on a systemic approach, recommended in current published clinical guidelines and research findings, with consistent evidence, as the first-line treatment of patients with anorexia nervosa.
ObjectivesA case of a patient with anorexia nervosa, is presented followed by a theoretical review on the topic.
MethodsA case is presented with a bibliographic review.
ResultsA 24-yeard-old female was hospitalized for renutrition due to a significant weight loss and multiple physical symptoms. After 4 months without progress, the patient was transferred to the psychiatric ward.
Once there, physical stabilisation was achieved with family therapy and pharmacological treatment, based on progressive administration of Clomipramine, previously assessed by Cardiology, which improved rumination and obsessive behaviour. We conduct daily individual and weekly family interviews, working on family dynamics, emotional regulation strategies and more adaptive ways of communication. Likewise, several lines of action were found in the systemic work: peripheral father; maternal over-involvement; fraternal rivalry; difficulties of interaction between all of them, derived from “the role of the sick person” and intra-family communication around the illness. Finally, showed effectiveness in terms of an improvement in interpersonal relationships, greater assertiveness and an optimistic attitude with an active search for coping strategies.
ConclusionsHistorically, parents have been recognized by a causal factor in the pathogenesis of this disorder. Nevertheless, the abolition of the emphasis on family responsibility, motivated by a philosophic and evidence-based, has allowed us to see them as an essential resource in aiding the patient in the improvement process. This parental involvement has resulted in a relevant reduction in morbidity, as well as a significant decrease treatment attrition rates. It has been noted a re-establishment in other individual and family factors such as self-esteem, quality of life, and some aspects of the experiences of caregiving, and behavioral symptoms have been resolved.

Introduction
CD is characterized by at least three features: its duration is prolonged, it does not resolve spontaneously and it is rarely completely cured. Approximately 10-15% of young people have CD. Adolescents with CD often have emotional and behavioral problems.
ObjectivesTo assess risk factors, derived psychiatric pathologies and coping strategies for a CD diagnosis in adolescence.
MethodsAn extensive literature review was carried out on the subject in question, extracting information mainly from scientific articles, manuals and books.
ResultsThe main risk factors are those related with the CD in question, physical sequelae, the need for long-term hospital admissions or the use of drugs whose side effects include affective or behavioral symptoms; those related to the personality traits of the affected child or adolescent. In addition, as far as the family is concerned, the presence of a low level of education, lack of support or communication, as well as the presence of psychiatric disorders or serious medical conditions in parents. Among the most frequent psychiatric disorders associated with CD are affective and anxiety disorders, adaptive disorders, somatoform disorders, eating disorders and behavioral disorders. Whatever the CD is, it generates high levels of stress and uncertainty in the patient and family, which must be dealt together from a flexible perspective, allowing child or adolescent to adapt to the changes, reorganize and facing them with adaptive patterns of behavior. For this, it will be essential to have adequate social and family support with relational style based on communication, trust and acceptance.
ConclusionsIn general, both adolescents with CD and their families have an adequate capacity to adapt to the repercussions and effects derived from the disease. Nevertheless, in case of possible emotional difficulties that may appear, a comprehensive and individualized approach to these adolescents and their families is necessary to provide them resources and coping strategies in different areas and contexts in which the disease debuts.The comprehensive therapeutic approach will consist of interventions at the individual and family level. Among the main objectives of these interventions are to achieve acceptance and adaptation to CD provinding adequate psychosocial support to enable them to cope with CD in the best possible way and to detect and address the emotional implications, even coexisting psychopathology.

Introduction
Corticosteroids are drugs widely used in clinical practice for their anti-inflammatory and immunosuppressive properties. Despite their beneficial effects, a high association of these drugs with neuropsychiatric adverse effects such as psychosis, mania, depression, delirium or increased risk of suicide, among others, has been observed. We present the case of 54-year-old man who started treatment with hydroaltesone 20 mg/8h after undergoing surgery for a pituitary macroadenoma who began with maniform clinic.
ObjectivesTo know the prevalence, risk factors and treatment of mania as a side effect of corticosteroid drugs.
MethodsPresentation of the case and review of the available literature on the risk of developing mania after corticosteroid treatment.
ResultsSeveral studies confirm that the incidence of psychiatric adverse effects after the use of corticosteroids is around 6% if we refer to severe reactions; 28% moderate reactions; and 72% if we consider milder reactions. The direct relationship between these drugs and affective symptoms ranges in rates between 1-50% of cases, the most frequent being depression and mania. The risk of mania after treatment with corticosteroids is 4-5 times higher than if we compare it with a group of population not exposed to these drugs. There is a dose-response relationship, increasing the risk from a daily dose of 40 mg/day, with an average duration of symptoms of around 21 days. Female sex seems to be a risk factor in relation to the fact that diseases requiring this type of treatment are more common in this gender. As first-line treatment for mania secondary to corticosteroids, a decrease in treatment dose or its interruption, whenever possible, is proposed. Adjuvant treatment may be required, with atypical antipsychotics being the first choice.
ConclusionsCorticosteroid therapy has a direct dose-response relationship with the presence of psychiatric adverse effects such as mania. Dose and sex have been studied as possible adverse effects. Therefore, the pharmacological treatment of choice consists of a reduction in the dose of corticosteroids administered or withdrawal, if possible, and may be combined with an atypical antipsychotic such as olanzapine, quetiapine or risperidone. Re-evaluation is recommended until complete resolution of the clinical picture and then antipsychotic treatment can be progressively withdrawn.

Introduction
We have investigated the relationship between the Psychosomatic Classification method (Marty) and the Rorschach Test, with respect to the diagnosis of psychosomatic disorders, within the framework of the degree of mentalization measured by both.
ObjectivesA) To verify statistical coincidence with respect to the degree of mentalization (risk of generating psychosomatic disorders in a subject) between the Rorschach Test and the diagnostic technique Psychosomatic Classification, by P. Marty. B) To test the hypothesis: Patients diagnosed with infertility, whose degree of mentalization is good, will have a greater probability of achieving a successful pregnancy throught Assisted Reproduction Techniques.
MethodsTwo evaluation tools were used: a) Psychosomatic Classification based on the criteria established by this diagnostic method; b) The Rorschach test (based on the evaluation of 29 indicators, selected according to their greater relevance in the generation of somatic symptoms).
A sample of 120 patients (women) diagnosed infertility at the Assisted Reproduction Unit (U.R.A.) at Hospital Universitario 12 de Octubre in Madrid was recruited. The method of ‘statistical correlation of coincidence’ between the results of the two diagnostic instruments used was used. Once both tests had been assessed by the “inter-judge” method and the quantitative values of the selected items had been weighted, the KAPPA statistical method was applied to establish the “correlation of coincidence” between the results of the two assessment instruments.
ResultsConsidering that the KAPPA method takes values between “0" and ”1" and that between 0.6 and 0.8 the agreement or coincidence is considered good, and above 0.8 very good, the result applied to the hypothesis is 0’76 (’good’).
ConclusionsA) Using the Rorschach Test and P. Marty’s Psychosomatic Classification in a complementary manner, these two instruments together provide high reliability, with respect to the degree of mentalization (a subject’s risk of suffering psychosomatic disorders). B) The degree of mentalization has a significant impact on the success or failure in the application of Assisted Reproduction Techniques in infertile women.
