Cannabis use and familial vulnerability to psychosis have been associated with social cognition deficits. This study examined the potential relationship between cannabis use and cognitive biases underlying social cognition and functioning in patients with first episode psychosis (FEP), their siblings, and controls.

We analyzed a sample of 543 participants with FEP, 203 siblings, and 1168 controls from the EU-GEI study using a correlational design. We used logistic regression analyses to examine the influence of clinical group, lifetime cannabis use frequency, and potency of cannabis use on cognitive biases, accounting for demographic and cognitive variables.

FEP patients showed increased odds of facial recognition processing (FRP) deficits (OR = 1.642, CI 1.123–2.402) relative to controls but not of speech illusions (SI) or jumping to conclusions (JTC) bias, with no statistically significant differences relative to siblings. Daily and occasional lifetime cannabis use were associated with decreased odds of SI (OR = 0.605, CI 0.368–0.997 and OR = 0.646, CI 0.457–0.913 respectively) and JTC bias (OR = 0.625, CI 0.422–0.925 and OR = 0.602, CI 0.460–0.787 respectively) compared with lifetime abstinence, but not with FRP deficits, in the whole sample. Within the cannabis user group, low-potency cannabis use was associated with increased odds of SI (OR = 1.829, CI 1.297–2.578, FRP deficits (OR = 1.393, CI 1.031–1.882, and JTC (OR = 1.661, CI 1.271–2.171) relative to high-potency cannabis use, with comparable effects in the three clinical groups.

Our findings suggest increased odds of cognitive biases in FEP patients who have never used cannabis and in low-potency users. Future studies should elucidate this association and its potential implications.

The harmful consumption of alcohol is known for how tortuous its management can be in mental health, encouraging introspection of it as a serious problem is perhaps the main key to starting to battle against its damaging influence on the development of a functional and full life.

To describe a clinical case showing an unpredictible complication in an alcohol detoxification process.

54-year-old man, native of Cádiz, widowed for half a decade, without children. He resides with his parents in the family home. Currently unemployed for approximately a year. He has previously worked in the IT sector. As a notable somatic history, we found long-established arterial hypertension and a total hip replacement. He has been under irregular follow-up with a mental health team for anxiety-depressive symptoms in the context of grief. He goes to the emergency service brought by his family to begin the detoxification process in the hospital setting. He acknowledges ethanol consumption since he was widowed, which began when he awakes; quantities that ranged between one or up to three bottles of distilled liquor per day, generally consumption is in the home environment. A little less than a year ago, he began to isolate himself in his room and abandon his self-care, eating increasingly insufficient food intake, refusing to receive professional care to quit the habit, mainly because he did not recognize it as disruptive.

The patient was admitted to hospital with symptoms suggestive of withdrawal, making it extremely difficult to control blood pressure levels. On the third day of admission to the acute care unit, fever peaks, blood pressure levels well below normal parameters, and compromised level of consciousness began to be evident.

Blood tests were performed that, together with the clinical picture, suggested imminent septic shock, so critical care was contacted for transfer and stabilization. A germ of probable urinary etiology sensitive to a broad spectrum of antibiotics was isolated in blood cultures, and the medication of the detoxification process was progressively optimized. Once clinical stability was achieved at all levels, an inpatient cessation resource was managed, which the patient accepted and considered suitable for his complete recovery.

A holistic approach to the alcoholic patient is important, since serious problems of an organic nature often arise. This is why a multidisciplinary intervention is necessary, as well as a holistic approach to care, involving both classic pharmacology and assiduous long-term psychotherapeutic intervention.

Diagnostic stability is a controversial issue in first episode psychosis (FEP) due to heterogenous symptoms and unclear affective symptoms. Differencing affective and non-affective psychoses is important as treatment strategies are different. Initial affective symptomatology has low specificity for predicting the subsequent diagnosis of affective psychosis. Sex has proven to be relevant for clinical and functional outcomes but it remains unclear how sex may contribute to diagnosis switch of FEP.

To determine the role of sex in diagnostic stability in a sample of FEP after 1-year follow-up.

Diagnoses of FEP patients from Hospital del Mar of Barcelona were assessed at baseline and 1 year after. Univariate analyses was perfomed for all diagnoses and dichotomic variable (affective/non-affective). Logistic regression model was perfomed to know which variables predict diagnosis switch.

256 patients were enrolled. No differences were found at baseline between completers and non-completers (Table 1). No significant differences between men and women at baseline diagnosis were found, neither all diagnoses (p=0.274) nor the dichotomic variable affective/non-affective (p=0.829) (Table 2AB). Significant differences were found at 1-year follow-up between men and women, for all diagnoses (p=0.043) and the dichotomic variable (p=0.039). Sex was the only variable that predicted diagnosis switch (Figure 1), PANSS, CDSS, YMRS, GAF and cannabis did not.Table 1.

Intranasal esketamine has been approved as a treatment for patients with treatment-resistant depression. We analyzed the results of its efficacy in 15 patients.

To evaluate the efficacy of intranasal Esketamine as a treatment in patients with treatment-resistant depression

Case series

For the last 8 months, since the treatment with intranasal esketamine was approved for resistant depression, we have treated 14 patients with this drug. Through this process, we followed a standardized method consisting in the following steps:

On the first esketamine session (DAY 1) the patient has to fill a CGI and a MADRS scale.

On the second esketamine session (DAY 7) the patient has to fill a CGI, a MADRS scale, a form about the level of satisfaction with the drug and a last form in which they can include the secondary effects.

On week 6 since the start of the treatment, the patient has to fill again a CGI, a MADRS scale, a form about the level of satisfaction with the drug and a last form in which they can include the secondary effects.

In the 6th month since the start of the treatment, the patient has to fill again a CGI, a MADRS scale, a form about the level of satisfaction with the drug and a last form in which they can include the secondary effects they have perceived.

We analyzed and compared all of the previous data and obtained the following results:

At day 7: 64% of the patients had a response in the form of improvement, of which 66% were feeling “slightly better” and 33% were feeling “better”.

At week 6: 71% of the patients had a response in the form of improvement, of which 50% were feeling “slightly better” and the other 50% were feeling “better”.

At month 6: only 28% of the patients completed the treatment; of which 100% had a response in the form of improvement: 50% were feeling “slightly better”, 25% were feeling “better” and 25% were feeling “far better”.

Although our data suggests that intranasal esketamine has been effective in short term depressive symptoms, we have yet no information about its medium and long-term efficacy or secondary effects. Nevertheless, other potential factors should be evaluated as they could affect the results in the long-term such as the difficulty in maintaining the treatment for more than 6 weeks.

In addition, the patients who experienced the most improvement according to our data were patients with a TAB diagnosis, so this could be an interesting research focus.

The Positive and Negative Syndrome Scale (PANSS) has been used as a universal instrument for clinical assessment of psychopathology in schizophrenia. Different studies have analyzed the factorial structure of this scale and have suggested a five-factor model: positive, negative, excited, depressive, and cognitive/disorganized factors. Two of the most used models are the Marder´s solution and the Wallwork´s one.

The aim of this work was to study the correlations of the two cognitive factors (Marder and Wallwork) with a cognitive assessment performed with a standard cognitive battery, in a sample of patients with first psychotic episode of schizophrenia.

Seventy four patients with first psychotic episode of schizophrenia (26.9, SD:7.8 years old; 70.3% male) were included. The cognitive assessment was performed with the MATRICS Consensus Cognitive Battery (MCCB). The MCCB present seven cognitive domains: Speed of processing, Working memory, Attention/Vigilance, Verbal Learning, Visual Learning, Reasoning and Problem Solving, and Social cognition). Pearson correlations were performed between MCCB scores and Marder´s PANSS cognitive factor (P2, N5, G5, G10, G11, G13, G15) and Wallwork´s one (P2, N5, G11).

Correlation between MCCB scores and cognitive factors of Marder and Wallwork can be seen in the table.

Both PANSS cognition factors show a moderate correlations with Speed of processing, Working memory, Attention/Vigilance and Verbal Learning assessed by MCCB. More discrete correlations were found with Visual Learning, Reasoning and Problem Solving, and with Social cognition (in fact, non-significant correlation with Wallwork´s cognitive factor was found).

A 28 year old patient will be presented. This paramilitary man was brought to the Emergency Room due to an autolytic attempt with Benzodiazepines, along with a mouth suture, in the context of a soon to be resolved problematic ankle osteosynthesis procedure. The patient claimed to be suffering pain, furthermore struggling due to the fact he could not be working due to his ankle issue. Language barrier was a problem during the interview.

The objetives of this case is to try to explain the issues that may arise in patients with personality disorders in the context of an autolytic attempt

This patient will be presented, along with systematic bibliography review of the topic.

The following results were extracted upon the attention given to this patient which was admitted to the Psychiatric Unit.

First of all, the mouth stitches were removed, along with a petition for toxicological analysis. The results gave positive for cannabis and benzodiazepines. The patient was also brought previously this year with another autolytic attempt, this time on cocaine consumption too. Furthermore, a thorough review was made of the other autolytic attempts, including those which happened in his country of origin. The patient has hundreds of small cuts among his arms, from previews cuts made in the past. Furthermore, subcutaneous wounds were auto inflicted in the ER, with a small blade.

Among the whole interview, it was clear he had a personality disorder, with high impulsivity levels and lack of control once the situation overflows.

We also tried to understand the outcome of suturing his mouth. The patient referred his acts of impulsiveness due to his overwhelming situation of both having no job at this moment and the pain he was suffering due to his ankle procedure.

The patient was admitted to our Unit due to the high risk he could repeat this act. Upon arrival, the same day he was admitted, the patient asked if he had to stay at the unit. When explaining the following already told event, furthermore insisting in the possibility of been evaluated by the Traumatology team, he proceeded to try and hang himself with his medical-hospital clothing.

The patient was treated with antipsychotics. Along with Lormetazepam at night. At the end of the hospitalization, and after been evaluated by the Psychiatrist of this Unit, the patient was also treated with Lithium due to its effectiveness in the treatment of autolytic attempts.

Personality disorders are one of the psychiatric pathologies that prevail with greater frequency in autolytic attempts 1. Additionally, it should be taken into account the possible ongoing consumption of psychoactive drugs that could also derive in psychopathological decompensation. On top of the following, the use of antipsychotic treatment is indicated for the managing of conduction altercations 2, besides Lithium being a great option in managing suicidal temptations 3.

An increased risk of suicide has been reported by psychiatric patients, including schizophrenia1. Numerous evidence suggests alterations in the grade of pro-inflammatory impact on suicidal behavior2, and this relation has been shown in patients with mood or anxious disorders3,4. However, the grade of inflammation impact suicidal behavior in patients with schizophrenia has hardly been investigated.

Identify peripheral blood biomarkers of suicidal behavior in patients with schizophrenia, including inflammatory and lipid profile parameters.

Secondary analysis of a cross-sectional study. Sample: 254 patients with schizophrenia, aged 18-72. Assessments: ad-hoc demographic and clinical questionnaire, PANSS, CDS, CAINS, PSP. Inflammatory and lipid parameters: C-reactive protein (PCR), interleukin 6 (IL-6); high-density lipoprotein cholesterol (HDL-C), low density lipoprotein cholesterol (LDL-C), total cholesterol (TC), triglyceridaemia (TG). Statistical analysis: Correlations, T Student, U Mann-Withney and lineal regression.

Mean age: 40.49 (13.10). Men: 64.2%.

No statistically significant differences were found between patients with suicide attempts and those without in any of the inflammatory or lipid parameters (p>0.05). However, differences were found in terms of suicide attempts (yes/no) in the PANSS negative (T=-2.217; p=0.028) and PANSS general psychopathy (T=-4.224; p< 0.001), in depressive symptoms (T =-6.967; p< 0.001), and the MAP subscale of the CAINS (T= -3.741; p<0.001).

Among patients with suicide attempts (n=42; 16.52% of the sample) (mean=1.90; sd=1.73; Range:1-7), statistically significant correlations were found with PCR (r=0.309; p=0.046), but not with cytokines and lipid parameters. On the other hand, no correlations were found with age, sex, length of illness, and any of the clinical scales.

A multiple linear regression was performed considering the number of suicide attempts as the dependent variable and as independent variables, age, sex, and those that were significant in the bivariate analysis (PCR).

A predictive model was found that explains 9.60% of the variance of number of suicide attempts (F = 4.224; p < 0.001). The variable that entered the model was PCR (β= 0.309; p=0.046).

The increase in inflammation (manifested by the elevation of PCR) is related to an increase in the number of suicides. On the contrary, no correlations were found with lipid parameters or interleukins.

Schizotypal personality is a condition suffered by 4% of the population. It is defined by presenting interpersonal, behavioral and perceptual features similar to the clinical features of psychotic disorders, such as schizophrenia, in less intensity and dysfunctionality, but at risk of reaching psychosis.

Presentation of a clinical case about a patient with premorbid schizotypal personality traits presenting with an acute psychotic episode.

Literature review on association between schizotypal personality and psychosis.

A 57-year-old woman with a history of adaptive disorder due to work problems 13 years ago, currently without psychopharmacological treatment, goes to the emergency room brought by the emergency services due to behavioral alteration. She reports that “her husband and son wanted to sexually abuse her”, so she had to run away from home and has been running through the streets of the town without clothes and barefoot.

Her husband relates attitude alterations and extravagant behaviors of years of evolution, such as going on diets of eating only bread for 40 days or talking about exoteric and religious subjects, as believing that the devil got inside her husband through a dental implant. He reports that these behaviors have been accentuated during the last month. She has also created a tarot website, and has even had discussions with several users. She is increasingly suspicious of him, has stopped talking to him and stays in his room all day long, with unmotivated laughter and soliloquies.

It was decided to admit him to Psychiatry and risperidone 4 mg was started. At the beginning, she was suspicious and reticent in the interview. As the days went by, communication improved, she showed a relaxed gesture and distanced herself from the delirious ideation, criticizing the episode.

In recent years, there has been increasing interest in understanding the association between schizotypy and serious mental disorder. Several theories understand schizotypy as a natural continuum of personality that reveals genetic vulnerability and that can lead to psychotic disorder when added to precipitating factors. Other theories define schizotypy as a “latent schizophrenia” where symptoms are contained and expressed in less intensity.

Around 20% evolves to paranoid schizophrenia or other serious mental disorders. It is complex to distinguish between those individuals in whom schizotypy is a prodrome and those in whom it is a stable personality trait. To date, studies applying early psychotherapeutic or pharmacological interventions have had insufficient and contradictory results, and the follow-up and treatment of these individuals could be a stress factor and a stigma. Some studies are looking for reliable markers of evolution to schizophrenia in order to establish adequate protocols for detention, follow-up and treatment.

Conversive disorder is characterised by the presence of one or more involuntary neurological symptoms that are not due to a clear medical pathology. On the other hand, consciously simulated illnesses fall into two diagnostic categories: factitious disorders and malingering, which are differentiated by both the motivation for the behaviour and the awareness of that motivation. Factitious disorder behaviours are motivated by an unconscious need to assume the sick role, whereas malingering behaviours are consciously driven to achieve external secondary gains.

Study of the differences between conversion disorder and factitious disorder and their repercussions from a case of difficult diagnosis.

Bibliographic review of scientific literature based on a relevant clinical case.

We present the case of a 14-year-old male patient. Adoptive parents. Studying in high school. Social difficulties since childhood. He comes to the emergency department on several occasions referring stereotyped movements and motor tics in the four extremities with left cervical lateralization. Increase of these symptoms in the last month, so it was decided to admit him to the pediatric hospital. After observation and study of the patient’s movements with normal complementary tests he should return home. The following day he returned to the emergency department after an episode of dizziness, mutism and emotional block. It was decided to admit him to Psychiatry for behavioral observation and differential diagnosis.

In the assessment of patients it is essential to make an appropriate diagnosis taking into account the patient’s symptomatology and the patient’s background and life context. Conversion disorder is the unintentional production of neurological symptom, whereas malingering and factitious disorder represent the voluntary production of symptoms with internal or external incentives. They have a close history and this has been frequently confounded. Practitioners are often confronted to medically unexplained symptoms; they represent almost 30% of neurologist’s consultation. The first challenge is to detect them, and recent studies have confirmed the importance of “positive” clinical bedside signs based on incoherence and discordance. Multidisciplinary therapy is recommended with behavioral cognitive therapy, antidepressant to treat frequent comorbid anxiety or depression, and physiotherapy. Factitious disorder and malingering should be clearly delineated from conversion disorder. Factitious disorder should be considered as a mental illness and more research on its physiopathology and treatment is needed, when malingering is a non-medical condition encountered in medico-legal cases.

Short-chain fatty acids (SCFA) are bacterial metabolites that, within microbiome-gut-brain axis, make a promising research line on etiopathology of mental diseases like schizophrenia (SZ) and major depression disorder. Besides, depressive symptoms are frequent clinical features of SZ.

• - Describe fecal SCFA concentrations in SZ patients.

• - Analyze differences in SCFA depending on:

• - Depression.

• - Clinical severity, antipsychotics and antidepressants, comorbidities (pro-inflammatory state/obesity/metabolic syndrome [MetS]), lifestyle.

Cross-sectional study of 67 outpatients [mean age=43.52±12.42, range=22-67; males=40 (59.7%)] with diagnosis (DSM-5) of SZ recruited from their mental health clinics in Oviedo (Spain).

• - Assessment:

• - Fecal SCFA (gas chromatography;μg/mL).

• - Plasmatic C-reactive protein (CPR;mg/dL).

• - PANSS, Calgary Depression (CDS), International Physical Activity (IPAQ), Mediterranean Diet Adherence (MEDAS).

• - Toxic habits (alcohol use/smoking/cannabis).

• - Chlorpromazine equivalent doses (CPZ-ED), use of antidepressants.

• - MetS (ATP-III), body mass index (BMI; kg/cm2).

• - Statistics: Spearman correlation, U Mann-Whitney, ANCOVA.

14 patients showed clinical depression (CDS≥5). There were no differences in age or sex between groups. 36 patients (53.7%) showed systemic low-grade inflammation (CPR≥0.3mg/dL) and 32 (30.8%) MetS.Table 1 shows fecal SCFA levels by depressive state. Means (SD) are ahown.Table 1

Correlations were found in Age with Butyrate (r=-0.248,p=0.043) and weekly alcohol units with Propanoate (r=0.250,p=0.041) plus trend to significance with Butyrate (r=0.232,p=0.059). It also showed a trend towards statistical relation for CPZ-ED with Propanoate (r=-0.253,p=0.039) and Total SCFA (r=-0.253,p=0.039). We found no correlation in SCFA with MetS, CGI, PANSS-N, BMI, IPAQ, MEDAS and other toxic habits.

ANCOVA was performed to Acetate and Total SCFA using depression state as independent variable and Age and CPZ-ED as covariates. There was a trend towards statistical significance for Acetate (F=3.937,p=0.052,η2=0.059) whereas Total SCFA showed no difference (F=1.350,p=2.250,η2=0.021).

There seems to be lower levels of fecal Acetate in SZ patients with depressive symptoms, considering age and antipsychotic intake. In our sample there was no relation between SFCA and clinical severity, lifestyle, comorbidities or antidepressant use.

Review of the scientific literature based on a relevant clinical case.

A 16-year-old woman was admitted to a psychiatric inpatient unit for psychotic symptoms and behavioural disorders. She lives with her father and older sister; she has not been in contact with her mother, who lives in another country, for several years. She attends secondary school, with poor academic performance. Maternal diagnosis of schizophrenia. She started using cannabis two years ago, with a progressive increase up to 20 grams per week. He reports the onset of a feeling of strangeness a year ago, with progressive isolation in his room, referring to delirious ideation of harm towards classmates and people from his town, self-referentiality and delirious interpretations of religious mystical content (“God speaks to me through a dove”). He comments on the phenomenon of theft and thought-reading. Soliloquies and unmotivated laughter are observed.

Treatment was started with risperidone, progressively increasing the dose up to optimisation, without achieving a decrease in positive symptoms, but with the appearance of excessive sedation and sialorrhoea. It was combined with aripiprazole up to 20mg, maintained for a couple of weeks, without significant clinical improvement. Given the failure of two lines of therapy, it was decided to change to clozapine up to a dose of 75mg, with adequate tolerance and response, achieving a distancing of the delirious ideation. Regular haematological controls were performed, with no alterations in haemogram or troponins.

An increase in suicidal behavior among the adolescent population is reflected in the literature and in clinical practice. According to a study of suicidal behavior and mental health by the Spanish ANAR Foundation, the number of cases with suicidal behavior has experienced an accentuated growth in the period 2012-2022 (1,921.3%), highlighting the increase produced in the post-COVID-19 period, between 2020 and 2022 (128%)

To analyze the reasons for admission to the short hospitalization unit. To describe the sociodemographic characteristics of hospitalized adolescents.

Descriptive observational study of the sample of adolescents admitted to the inpatient psychiatric unit of the Hospital Universitario Puerta de Hierro between January 1, 2023 and June 30, 2023. It is carried out through the information obtained in the clinical history of the patients.

During this period of time 113 adolescents were admitted, 80.2% were female. The mean age was 15.16 years. The main reason for admission was autolytic ideation, occurring in 33.3% of the patients. The second most frequent reason for admission was suicide attempt (29.7%) and behavioral disturbance (17.1%) was the third most frequent. Of the methods used in suicide attempts, drug overeating stands out among the methods used in suicide attempts. (75.8%), followed by attempted hanging (12.1%) or cutting (12.1%).

Image:

The results corroborate what is reported in the scientific literature, where self-harm and self-injury attempts have increased and are the most frequent reasons for admission. This shows that suicide is a public health problem of the first order, where prevention and early intervention programs are necessary.

Psychotic patients are a vulnerable population from a social and health point of view. The SARS Cov-2 pandemic affected millions of people around the world, however, its effects on psychotic patients in Avilés Spain, have not been analized.

The objective of this study was to determine and compare the mortality of patients with psychosis due to SARS Cov-2 in Avilés, Spain with others regions and countries in the European Union. Determine the influence of social condition and antipsychotic treatment on the condition of these patients.

This is a descriptive, observational study, in which patients diagnosed with psychosis in the period 2020-2021 who contracted SARS Cov-2 infection in Avilés, Spain, were studied to determine those who died from this cause. The influence of social status and antipsychotic medication, as well as sociodemographic factors (age, sex, marital status) were analyzed and compared with other regions and countries of the European Union.

Despite the high mortality rate in patients with psychosis, during the years of the pandemic SARS Cov-2 played an important role given the vulnerability of these patients.

The negative effects and deaths during the COVID-19 pandemic were at the time a major problem for public health worldwide. This study concluded that the morbidity and mortality of psychotic patients who contracted COVID-19 was lower than the rest of the population.

Benzodiazepine use disorder (BUD) has been associated with the presence of suicidal ideation (SI) in general population. It seems there is an overall increase in the risk of attempting suicide due to the increase of impulsivity, rebound and withdrawal of those who use benzodiazepines(1). However, this association has been scarcely studied.

To explore the prevalence, clinical features and factors related to lifetime SI in adults with BUD.

A cross-sectional study was conducted in an outpatient center for addiction treatment between 01/01/2010 and 12/31/2021. Adult patients who met criteria for active BUD were included. Patients with language barriers, cognitive impairments and those who were participating in any clinical trial were excluded. All patients were evaluated with an ad-hoc questionnaire, EuropASI (European Addiction Severity Index), BDI (Beck Depression Inventory) and HRQoL SF-36 (Health-related quality of life according to SF-36). Univariate and bivariate analyses were performed comparing BUD patients with or without SI.

554 patients were included (65.2% males; M age 42.6±12.6 years). SI was reported in 57.2% of the patients. Regarding the sociodemographic variables, any type of lifetime abuse was correlated with SI (67.8%, 73.5% and 77.8% of the patients with emotional, physical and sexual abuse respectively). Considering the different psychiatric features studied, having any psychiatric diagnosis increased SI up to 64%. Depressive and cluster B personality disorders were the ones with a higher presence of SI (67.1% and 68.1% respectively). Anxiety and cluster A personality disorders had also higher proportions of SI (56.1% and 58,7% respectively). Regarding the different assessment instruments used, a higher punctuation on BDI score was seen in the group of patients with SI (23.73±12.86). The scores also showed a worse perception of the mental quality of life of those people with SI, measured by HRQoL (13.76 and 36.82±31.93 in patients with SI and no SI respectively). Considering the EuropASI, there was an increased proportion of SI in those patients with a worse familiar situation (0.44±0.30), a higher alcohol consumption (0.26±0.28) and a worse psychological condition (0.48±0.24).

The prevalence of SI in patients with BUD is significative and is related to several clinical factors. Those factors should be taken into account in daily clinical practice, research, and any health policies on suicide. Further research should be developed.

Ageing populations with increased needs, rising costs of traditional services, and new technologies are some factors driving the use of e-health services. A Norwegian study with data from 2015-2016 found that 13.5% had used apps, 7.3% had used social media, and 5% had used video services for health purposes. Little is known about the effects of many online health services, but in general they seem to increase knowledge and make most people feel reassured, although some users feel more anxious or confused after using such tools. Recent technological developments have resulted in new online health services, including AI-based technologies. More updated knowledge regarding the population’s use of e-health services in general and e-mental health services in particular, is needed.

The objective here is to provide information about an upcoming large population-based epidemiological study and how it addresses e-health and e-mental health.

We introduce the upcoming 8th version of the epidemiological Tromsø Study and discuss its importance to the field of e-mental health.

The Tromsø epidemiological study has since 1974 taken place in the Norwegian municipality of Tromsø. It contains information on a range of topics within health and illness, including topics from many medical specialities, psychiatry and substance use. In the upcoming 8th version of the study (2025-2026), more than 33,000 people aged above 40 will be invited to participate. The main questionnaire will include questions relating to a wide variety of topics, including on e-health use. We suspect the importance of e-health and e-mental health have increased lately, and we will examine how the use of e-health may impact mental health.

Community-based studies, such as the Tromsø Study, allow researchers to study associations between many different variables, including mental health and e-health. The upcoming Tromsø 8 study will enable us to study e-health use and its relationship to mental health in a large sample representative of the Norwegian population.

Lithium was the first mood stabilizer and today continues to be a first-line treatment in the treatment of bipolar disorder despite its adverse effects, which make it important to monitor blood levels and control kidney function.

Presentation of a case of litium withdrawal and relapse in bipolar disorder. Literature review relating to the risk of relapse when lithium treatment is interrupted.

We present a clinical case of a patient who suffers a deterioration in renal function that requires the withdrawal of lithium and who consequently suffers a relapse. We conducted a bibliographic research of articles in Pubmed on this topic.

A 49-year-old male, with a history of multiple admissions to UHB since the age of 18 with a diagnosis of bipolar disorder and treatment with lithium. Decompensations towards the manic pole have always been related to interruptions in lithium treatment. On several occasions when the patient was feeling well emotionally, he believed himself to be “cured” and abandoned the treatment, triggering a manic episode, showing verbal aggression, increased self-esteem and delusional ideation of harm. Remission was usually achieved with the reintroduction of lithium and the addition of high-dose quetiapine. Between episodes, constant overvalued ideas of economic scarcity seemed to persist, which were accentuated in the form of delusional ideas of ruin in depressive decompensations. After 7 years of stability, control analysis showed blood litemia of 2.2 mEq/L with deterioration of kidney function and generalized tremor was observed, without improvement after serum therapy. He was admitted for dialysis and lithium was suspended. Treatment with valproate was started and a consultation scheduled in a week to adjust the dose. The patient did not attend that consultation and was admitted three days later to Psychiatry Hospitalization showing a challenging attitude, evident dysphoric mood, accelerated speech, with derailments and echolalia. Delusional ideation of harm with auditory hallucinations. Insomnia and hyporexia. Chronic renal failure persisted.

Lithium is a very effective drug but with a narrow therapeutic range that requires adequate monitoring due to the possible consequences of its use at different organs and systems of the body. when lithium is found in the blood at toxic levels with deterioration of kidney function and glomerular filtration fails to recover, lithium treatment should be suspended. Sudden withdrawal of lithium significantly increases the risk of relapse due to rebound effect. More than 50% of patients experience a recurrence within 10 weeks of withdrawal.

Given that child and adolescent mental health has been affected by several factors in recent years, such as the distance between home and specialized centers that provide psychological care to children, the lack of care resources, or the lockdown caused by the COVID-19 pandemic, online psychological treatments are becoming increasingly common among the child and adolescent population, although it is necessary to develop this type of treatment for children at psychosocial risk, since these have been developed mostly for the general population. To this aim, the Online Emotional Self-Regulation Improvement program (Mejora de la Auto-regulación para Menores, Online MAM@) was developed.

To assess the acceptability of the Online Emotional Self-Regulation Improvement program, by the adolescent.

The intervention program was applied to a total of n = 32 children (n = 17 girls) between 11 and 15 years of age. The program consists of 7 target emotions to be worked on, and the acceptance, usability, usefulness, enjoyment of each module and barriers to use by the children were assessed with an adaptation of the Venkatesh and Davis scale. These measures were taken post-test, once the intervention module was completed. The program was applied online for five weeks by the children, and their regular therapists contacted them to provide them with weekly access codes and reminders in case they were not completing the modules.

It was observed that the best rated module was the anger module, the most useful module was the sadness module, the module considered to have the highest usability was the fear module, and the most enjoyed module was the sadness module, although all the modules had very high scores above the average and no significant differences were found in the rating of the modules between sexes. As for the most common barriers to use among the children, problems were found with the completion of the intervention, since they often forgot to access the web, and these did not apply what they had learned outside the intervention program.

The Online Emotional Self-Regulation Improvement program is the first program developed in Spanish language for adolescents at psychosocial risk, and may represent a breakthrough to consolidate these programs in the national scene and bring the therapeutic possibilities for adolescents to the same level as in other parts of the world. Focusing on future versions of the program, it would be advisable to reduce its length and incorporate activities outside the treatment program to guarantee a generalization of what is learned in the intervention program in everyday life situations.

Delusional parasitosis, also known as delusional infestation or Ekbom’s syndrome, is a rare psychotic disorder characterized by the false belief that a parasitic skin infestation exists, despite the absence of any medical evidence to support this claim. These patients often see many physicians, so a multidisciplinary approach among clinicians is important. Many patients refuse any treatment due to their firm belief that they suffer from an infestation, not a psychiatric condition, so it is crucial to gain the trust of these patients.

The comprehensive review of this clinical case aims to investigate Ekbom syndrome, from a historical, clinical and therapeutic perspective.

Literature review based on delusional parasitosis.

A 65-year-old woman comes to the psychiatry consultation referred by her primary care physician concerned about being infested by insects that she perceives through scales on her skin for the last three months. She recognizes important impact on her functionality. She is also convinced that her family is being infected too. As psychiatric history she recognizes alcohol abuse in the past (no current consumption) and an episode of persecutory characteristics with a neighbor, more than ten years ago. On psychopathological examination, she shows delusional ideation of parasitosis, with high behavioral repercussions, cenesthetic and cotariform hallucinations, as well as feelings of helplessness and anger. Treatment with Pimozide was started and the patient was referred to dermatology for evaluation, a plan she accepted. Her primary care physician and dermatology specialist were informed about the case and the treatment plan. In the recent reviews, the patient is calmer, however, despite the corroboration of dermatology and in the absence of organic lesions in cranial CT, she is still unsatisfied with the results, remaining firm in her conviction of infestation. It was decided to start treatment with atypical neuroleptics (Aripiprazole), with progressive recovery of her previous functionality.

Despite the increase in the number of studies in recent years, there are still few studies on this type of delirium. The female:male ratio varies in the bibiliography (between 2:1 and 3:1). The onset is usually insidious, generally appearing as a patient who comes to his primary care physician convinced of having parasites in different skin locations. It is usual to observe scratching lesions or even wounds in search of the parasite. In the past, the most used and studied treatment was Pimozide. Currently the treatment of choice is atypical neuroleptics due to their lower side effects. The latest reviews on the prognosis of this disorder show data with percentages of complete recovery between 51% and 70%, and partial responses between 16.5% and 20%. Finally, for a good diagnosis and therapeutic management, it is important to achieve a multidisciplinary approach.
