Reward and threat processes work together to support adaptive learning during development. Adolescence is associated with increasing approach behavior (e.g., novelty-seeking, risk-taking) but often also coincides with emerging internalizing symptoms, which are characterized by heightened avoidance behavior. Peaking engagement of the nucleus accumbens (NAcc) during adolescence, often studied in reward paradigms, may also relate to threat mechanisms of adolescent psychopathology.

47 typically developing adolescents (9.9–22.9 years) completed an aversive learning task during functional magnetic resonance imaging, wherein visual cues were paired with an aversive sound or no sound. Task blocks involved an escapable aversively reinforced stimulus (CS+r), the same stimulus without reinforcement (CS+nr), or a stimulus that was never reinforced (CS−). Parent-reported internalizing symptoms were measured using Revised Child Anxiety and Depression Scales.

Functional connectivity between the NAcc and amygdala differentiated the stimuli, such that connectivity increased for the CS+r (p = .023) but not for the CS+nr and CS−. Adolescents with greater internalizing symptoms demonstrated greater positive functional connectivity for the CS− (p = .041).

Adolescents show heightened NAcc-amygdala functional connectivity during escape from threat. Higher anxiety and depression symptoms are associated with elevated NAcc-amygdala connectivity during safety, which may reflect poor safety versus threat discrimination.

As part of the intervention, patients with severe schizophrenia who are cared for in psychiatric rehabilitation units need psychological treatments. However, there is great variability within the psychotherapy alternatives that are proposed for rehabilitation in schizophrenia, and it is necessary to know which are the most efficient interventions in order to prioritize their inclusion in intervention programs.

To know the level of evidence of the existing psychotherapy alternatives for the rehabilitation treatment in schizophrenia through the systematic review of recently published studies.

Consecutive systematic searches in the scientific literature were used in a sensitive and specific way, aimed at identifying the existence of documents in databases and clinical practice guidelines based on evidence of psychological treatment in schizophrenia. Psychosocial and social approaches and family members interventions were excluded, and the search was limited to the last 5 years. The PICO format has been used, and a subsequent critical reading using the AGREE II tool, considering the inclusion criteria of presenting a score >60% in 4 domains.

The following interventions have been found to be therapeutically effective: Level 1B (Early intervention in Psychosis; Patient and Family psychoeducational intervention; Basic ando social skills training; Social cognition and Metakognition training; Cognitive Remediation; Cognitive Behavioral Individual Therapy; Assertive Community treatment; Supported employment). Level 2B (Family Problem Solving Therapy, Dynamic Psychotherapy; Cognitive Behavioral Group Therapy); Level 2C (Horticultural, Art, Music, Animals Therapies).

Several psychotherapy alternatives are proposed for rehabilitation in schizophrenia, with known level of evidenca in order to prioritize their inclusion in intervention programs.

Children and adolescents with ASD are more likely to have eating problems compared to the general population of the same age, one of the disorders whose prevalence is increased in people with ASD is avoidant/restrictive eating disorder Food (ARFID) ARFID is characterized by a lack of interest in eating or avoidance of food intake, which in the case of people with ASD is usually related to impaired sensory processing and cognitive rigidity. For this reason, the Autism Day Hospital carries out a specific food intervention program.

To retrospectively evaluate the results of the Food Program of the Autism Day Hospital during the year 2022.

A retrospective analysis of the cases of patients admitted to the Food Program of the Autism Day Hospital during the year 2022 is carried out. Results of the sensory pattern and presence of genetic alterations of each one of the patients are compared. And the results of the intervention are evaluated by quantifying the new foods introduced into the diet at the end of the admission.

The sample is made up of a total of 5 children (4 boys and 1 girl) aged between 7 and 12 years. All of them meet diagnostic criteria for Autism Spectrum Disorder and present comorbidity with ARFID. Of the total sample, 1 of the patients presented in the genetic study a microdeletion S. in 15q13.3, duplication in 2q13 and duplication in 5p12-p11, with the genetic studies in the rest of the patients in the sample being normal. Regarding the results of the sensory pattern (Infant/Toddler Sensory profile test), all the patients presented differences in relation to other children of their age in the oral sensory pattern, this difference being definitive in 3 of the 5 patients in the sample. All the patients included in the program presented a satisfactory evolution, introducing at least 15-20 new foods into their usual diet, including different textures and consistencies.

The therapeutic approach to ARFID in children with ASD carried out from a multidisciplinary perspective; sensory integration, behavioral approach and, if necessary, psychopharmacological, has shown, based on the results obtained from the food program of the ASD Day Hospital, a favorable evolution of the eating disorder. For this reason, we consider the detection of this typical comorbidity of ASD and its referral to specific therapeutic programs to be of special importance.

The ASD Therapeutic Day Unit is a tertiary care unit that consists of 20 beds, designed to facilitate the evaluation and treatment of children and adolescents with ASD who present high psychiatric comorbidity with behavioral problems, communication/language problems, sensory, and/or in the management of their repetitive and restricted interests. In addition to diagnosis and genetic counseling and clinical care, we offer the possibility of performing an individualized pharmacogenetic study in order to offer appropriate pharmacological treatment to patients with ASD and comorbidities.

The objective is to promote pharmacological tolerability, avoid unwanted side effects, as well as avoid the use of polypharmacy, in children with a tendency to poor drug metabolism.

A review of the medical history of the patients included in the Blood Extraction Program of the ASD Day Therapeutic Unit is carried out during the year 2022. The existing medications at admission, the results of the pharmacogenetic analyzes carried out, and the pertinent changes in the pharmacological treatment of these children.

37 children were included in the program during 2022. The genes CYP1A2, CYP2C19, CYP2D6, CYP3A4 and 5-HTT were analyzed. The variant studied is described, as well as the observed genotype and the expected phenotype.

Of the 37 patients, 11 maintained the same pharmacological treatment as at the beginning of admission, 5 were not taking pharmacological treatment and 25 underwent a treatment modification.

The most frequently modified treatment was risperidone with aripiprazole (n=10), secondly risperidone with guanfacine (n=5), and thirdly fluoxetine with aripiprazole (n=2).

Furthermore, the degree of pharmacological polytreatment was reduced. 18 patients switched to a single drug, instead of 14. 11 patients 2 drugs (instead of 14), 3 patients 3 drugs instead of 4 and 5 patients remained without drug treatment.

Patients with ASD have worse tolerability to pharmacological treatments than other patients with severe mental disorders.

The use of pharmacogenetics allows improving the cost/effectiveness of medical prescription, avoiding undesirable side effects or lack of effectiveness in the treatment of patients with ASD.

Promoting the implementation of pharmacogenetics in patients with ASD (among others) would improve the clinical situation of these patients more effectively and would improve the economic expenditure derived from erroneous prescription and/or excessive polypharmacy.

Abnormalities in social and emotional behavior are the major diagnostic criteria for behavioral variant frontotemporal dementia (bvFTD). Investigators have attributed their behavioral disturbances to disease in mesial prefrontal and related networks, such as the salience network. This study examined the main neural correlates of informant-reported socioemotional dysfunction among patients with bvFTD compared to those with early-onset (before age 65) Alzheimer's Disease (EOAD).

Participants included 13 patients with bvFTD and their caregivers and 18 patients with EOAD and their caregivers. The caregivers consisted of a spouse, family member, or other informant who resided with the patient. They completed the informant-based Socioemotional Dysfunction Scale (SDS), a 40-item scale which rates common disturbances in social and emotional behavior on a five-point Likert scale (1-5). The patients underwent magnetic resonance imaging (MRI) with tensor-based morphometry (TBM) analysis of the 3D T1-weighted MRI scans. Computations of mean Jacobian values within select regions of interest (ROIs) in frontal and temporal lobes generated numerical summaries of regional volumes, and voxel-wise regressions created 3D statistical maps of the association between tissue volume and SDS total scores. Statistical analyses included independent samples t-tests group differences in ROIs and SDS scores, Pearson correlations between SDS scores and brain volumes, and multiple regression of ROIs with SDS scores and group as predictor variables.

Compared to the EOAD group, the bvFTD group had significantly higher SDS scores (p < .001; d = 2.24), smaller frontal lobe volumes (specifically dorsolateral-prefrontal cortex, p = .003; d = 1.24), and larger temporal lobe volumes (specifically hippocampus, p = .014; d = 0.979). Within the bvFTD group, higher SDS scores were associated with a smaller right anterior temporal lobe (ATL; p = .005; r = -.729), especially the lateral ATLs (p = .002; r = -.776), and a smaller bilateral orbitofrontal cortex (OFC; p = .016; r = -.650). In contrast, within the EOAD group, higher SDS scores were associated with a smaller right parietal cortex (p = .030; r = .542). In the entire sample (both bvFTD and EOAD), higher SDS scores was associated with a smaller lateral ATL volumes (p = .019; r = -.431). Regression analyses confirmed that SDS score predicted lateral ATL volume (p = .041; b = -.262) after controlling for diagnosis (p < .001; b = -.692).

These findings are consistent with greater socioemotional dysfunction, smaller frontal, and larger mesial temporal regions in bvFTD, when compared to EOAD. The findings, however, suggest that positively disturbed socioemotional behavior in bvFTD, as reported by caregivers, results from involvement of the right temporal lobe and the lateral temporal region, with further contribution from disease in OFC. The association of SDS scores and ATL volume across diagnostic groups suggests that this region is instrumental in socioemotional functioning and that the SDS may have diagnostic value in distinguishing the "right-temporal variant" of bvFTD.

Global neurocognitive impairment (NCI) has been reported in white people living with HIV/AIDS (PLWHA) in 40%. In Latino populations there have been variable rates described from 30 to 77%. This variation has to do with the lack of normative data for Latino population and the application of norms for English-speakers, increasing the probability of misidentification of NCI. Thus, recognizing which are the best norms available for the Mexican population is important for the accurate identification of NCI. The aim of the present study was to investigate the rate and pattern of HIV associated neurocognitive impairment (NCI) and to compare rates of NCI between rates calculated using norms for the Latin-American population (NLAP) and norms for the US-Mexico border region (NP-NUMBRS).

CIOMS international ethical guidelines for the participation of human subjects in health research were followed. 82 PLWHA living in Tijuana (Mexico) participated in the study (Age: Mean=39.6, SD=10.9; 28.3% Female; Years of education: Mean=8.5, SD=3.6). PLWHA were recruited from the board-and-care home “Las Memorias” (73.4% on antiretroviral therapy; Years since HIV diagnosis: Mean=9.9, SD=7.1). Participants completed a neuropsychological test battery sensitive to detect HIV associated NCI that assessed four cognitive domains (verbal fluency, speed of information processing, executive function and learning/memory). Raw scores in these tests were transformed to percentiles using LAPN and transformed to T-scores using NP-NUMBRS. T-scores were averaged across tests to compute domain specific and global impairment scores. NCI was defined as percentile scores <16 and T-scores < 40. McNemar’s tests were used to compare the rate of NCI utilizing NLAP vs NP-NUMBRS.

According to NLAP, rates of global NCI were about 13.4%. Utilizing NP-NUMBRS rates of global NCI were about 34.1%. However, there is a positive and significant correlation between Global Neurocognitive Function score in PLWHA according to NLAP and NP-NUMBRS (r=0.66, p<.05). Rates of global NCI in PLWHA were significantly lower when using LAP norms (McNemar Chi-Square=29.89; p<.001). Regarding the pattern of NCI according both norms learning and memory was the most affected cognitive domain with 34% of impairment according to NLAP vs 51% of impairment according to NP-NUMBRs.

Utilizing NP-NUMBRS, rates of NCI are consistent with findings of prior studies. Employing norms for LAP the rates of NCI are lower that the ones reported in the literature. This is an important finding since PLWHA included in the sample have several vulnerable factors such as deportation, prostitution, drug abuse and discrimination for sexual preference, factor that could impact cognition. The pattern of neurocognitive function was also similar to those of prior studies in HIV. To accurately make NCI diagnosis it is important to use norms that consider specific characteristics of the population. The diagnosis of NCI is important since these deficits present a strong risk of concurrent problems in a wide range of health behaviors like medication non-adherence in PLWHA.

A 2020 study in Wuhan residents reported 70.2% of participants faced the COVID-19 pandemic using active coping strategies, and we wanted to explore its comparability in Chinese Health Care Workers (HCWs) across 7 regions in China 1 year after the initial outbreak.

The study analyzed coping strategies utilized by different Chinese HCWs under a stressful period like the COVID-19 pandemic and three psychological scales were used to assess its effect on five psychological outcomes such as depression, anxiety, stress, post-traumatic stress disorder and suicidal ideation.

A cross-sectional self-administered online questionnaire was conducted during the period of November 2020 and March 2021 and included sociodemographic information, work environment before and during the pandemic, experiences, fears and concerns about COVID-19 and three psychological scales including Depression, Anxiety and Stress Scale-21(DASS-21), Primary Care PTSD Screen for DSM-5 (PC-PTSD-5) and Simplified Coping Style Questionnaire (SCSQ-20). Chi-square analysis was used to explore categorical association.

The findings demonstrated that 633 (52.5%) of the participants used passive coping strategies, while 600 (47.5%) used active coping strategies. Passive coping strategies with at least one mental health problem were positively correlated with participants having a previous chronic disease diagnosis, working days in a week during the outbreak, PPE availability, days in isolation for being suspected or a confirmed case of COVID-19, worries about infecting relatives and the pandemic affecting family’s financial situation.

Developing and creating intervention programs to strengthen active coping strategies will improve mental health outcomes in Chinese HCWs during the COVID pandemic.

Currently, in addition to their frequent use in community medicine, the use of antidepressants is a fundamental pillar of pharmacological treatments used in psychiatry. Due to this frequent use, we must be aware of the possible side effects, in particular the SIADH produced in this clinical case by SSRIs. There are already described cases of this association including other antidepressants and many different types of drugs.

To review the current literature on the management of this pathology when it is secondary to the use of frequently used drugs such as SSRIs.

We report the case of a 64-year-old woman hospitalised in the psychiatric department for malnutrition secondary to unspecified eating disorder (ED). During admission, treatment with sertraline was started with ascending doses up to 100mg, subsequently producing slight edema with the following analytical results: plasma Na: 123 mEq/L (135-145), plasma osmolarity: 250 mOsm/kg (275-300), urinary Na: 174 mEq/L (>40), fulfilling diagnostic criteria for SIADH.

Afterwards, we reduced sertraline until discontinuation and started treatment with water restriction and urea (30 grams/24 hours) during admission and after discharge. During admission, we observed disappearance of the edema and partial improvement of the analytical values (Na:131 mEq/L), which were normalised with home treatment of daily urea.

The precise prevalence of SIADH from the use of SSRIs is unknown, it is known that patients older than 65 are at higher risk of developing severe hyponatraemia in the first 5 weeks after initiation. Similarly, treatment with water and urea restriction, together with discontinuation of SSRIs, appears to be sufficient.

SSRIs can cause SIADH a reversible but potentially life-threatening pathology, and we need to be aware of this possibility especially in the older population and being able to handle it

Fahr’s disease (FD) is a rare disorder consisting of bilateral and symmetrical calcium deposits in basal ganglia and cerebral cortex. These lesions are associated with neurological and psychiatric symptoms such as a rigid hypokinetic syndrome, mood disorders and memory and concentration abnormalities. It can be idiopathic or secondary to endocrine disorders, infectious diseases or mitochondrial myopathies.

To highlight the importance of considering organic causes when evaluating patients presenting atypical psychiatric symptoms and claim the role of neuroimaging.

Case report and non-systematic review of literature: sources obtained from Pubmed database.

A 69-year-old man, native of Syracuse (Italy), was admitted to the Psychiatry Unit in February 2022 presenting behavioural disturbances and irritability. In July 2021 he presented the same symptoms, being mistakenly diagnosed with Bipolar Disease type I. He has no previous psychiatric history. He started with changes in his personality, short-term memory loss, aggressiveness and disorganized behaviour at the age of 66. At admission he was talkative and hyperfamiliar, presenting delusions of grandiosity, exalted affectivity and insomnia. Neurological examination showed short-term memory problems, signs of frontal disinhibition and abnormal glabellar tap sign. Blood tests, CT brain and MRI were performed to rule out organic underlying causes. Neuro-imaging found bilateral and symmetric calcifications in globus pallidus, thalamus and corpus striatum, in favour of FD. Secondary causes (abnormalities in the PTH, vitamin disorders and infectious diseases such as HIV, brucellosis or neurosyphilis) where discarded, allowing us to conclude it was probably a primary case of FD. Valproate was started as a mood stabilizer and anticonvulsant. Genetic tests were indicated.

FD should be considered as a differential diagnosis in the evaluation of psychiatric symptoms, especially when atypical and/or presented with neurological symptoms. The role of neuro-imaging is essential.

It has been reported an inflammatory state in schizophrenia, with altered levels of some cytokines (Zhou et al. Cytokine 2021; 141:155441). Recent publications have shown the importance of IL- 33, a member of the IL-1 cytokine family which acts as an alarmin (Han et al. Neurosci Bull 2011; 27, 351-357). The role of this cytokine as a biomarker has been investigated in schizophrenia (Koricanac et al. Front Psychiatry 2022; 13, 925757). However, results are controversial. Some studies have not found significant associations between IL-33 and chronic schizophrenia (Campos-Carli et al. Compr Psychiatry 2017; 74 96-101), while other papers have reported increased levels (Kozlowska et. al. J Psychiatr Res. 2021; 138 380-387). In all these studies, levels of IL-33 were measured in a single daily measure, so that it has not been studied if IL-33 has changes during hospitalization.

To study the serum level of IL-33 at 12:00 and 00:00 hours in schizophrenia patients at admission and before hospital discharge.

Fifteen inpatients with diagnosis of paranoid schizophrenia according to ICD-10 criteria were studied. Patients were hospitalized at the University Hospital of the Canary Islands psychiatric ward because of an acute relapse. A total of four blood samples were taken from each patient: at 12:00 and 00:00 hours the day after admission and at 12:00 and 00:00 hours the day before discharge. Serum IL-33 levels were measured by ELISA techniques. Daytime and nighttime IL-33 serum levels at admission and discharge were compared using a non-parametric Wilcoxon signed-rank test.

In table 1 the results of the comparison of IL-33 at admission and discharge are presented. There is a significant reduction of IL-33 levels at 00:00 h. at discharge in comparison with the IL-33 levels at 00:00 h. at admission (p=0.028). No other statistically significant differences were observed.

The decrease of serum IL-33 at 00:00 at discharge compared to the 00:00 IL-33 serum level at admission points to the utility of this biomarker as a surrogate of brain inflammation.

Wenicke-Korsakoff syndrome (WKS) is a neurological disorder caused by thiamine deficiency. Wernicke Encephalopathy (WE) is the acute phase and the chronic phase is called Korsakoff-syndrome (KS).

To review the current literature on the management of WKS in a patient with anorexia nervosa.

We report the case of a 63-year-old woman admitted to the Psychiatry Unit after weight loss in the last 3 months (from 39 kg to 33,500 kg). She only made one meal a day. By exploration and analysis, neoplastic disease is ruled out (thoraco-abdomino-pelvic CT without pathological findings). She has maintained restrictive intakes for more than 30 years. A long-term anorexia nervosa (AN) is suspected, with a worsening of restrictive behavior in recent months. Upon admission, she has a weight of 33,500 kg and a BMI of 14,10. She has a left palpebral ptosis and an alteration of the anterograde memory as well as affectation of executive functions. Progressive oral diet is started, and due to the suspicion of a WKS, thiamine ev is started for a week and then continued with oral thiamine. Thiamine levels are extracted once the ev treatment has begun, so we do not have previous levels to know if they were decreased. Brain MRI shows bilateral hyperintensities in white matter and at supratentorial level in T2 and FLAIR. After a month and a half of admission, the patient has progressively regained weight, has managed to make adequate intakes and has improvement in memory.

An adverse consequence of severe malnutrition in AN due to severe food restriction and purging behavior is thiamine deficiency, and also global cerebral atrophy and concomitant cognitive deficits can be found. Thiamine deficiency occurs in 38% of individuals with AN and is often unrecognized. WKS is caused by thiamine deficiency, and WE is the acute phase of this syndrome (presentation of triad can vary). The chronic phase is KS and consists in amnesia with confabulations. WKS typically develops after malnourishment in alcoholic patients but can be associated in nonalcoholic such as prolonged intravenous feeding, hyperemesis, anorexia nervosa, refeeding after starvation, thyrotoxicosis, malabsorption syndromes; hemodialysis; peritoneal dialysis; AIDS; malignancy. WKS is a clinical diagnosis, and no specific abnormalities have been found in cerebrospinal fluid, brain imaging or electroencephalograms. MRI has a sensitivity of 53%, but high specificity of 93%, and shows an increased signal in T2 and FLAIR sequences, bilaterally symmetrical in the paraventricular regions of the thalamus, the hypothalamus, mamillary bodies, the periaquedutal region, the floor of the fourth ventricle and midline cerebellum.

If the disorder is suspected, thiamine should be initiated immediately in order to prevent irreversible brain damage, with an estimated mortality rate of about 20%, or to the chronic form of the WE in up to 85% of survivors

Methicillin-resistant Staphylococcus aureus (MRSA) infection is highly unlikely when nasal-swab results are negative. We evaluated the impact of an electronic prompt regarding MRSA nasal screening on the length of vancomycin therapy for respiratory indications.

Retrospective, single-center cohort study.

Tertiary-care academic medical center (Mayo Clinic) in Jacksonville, Florida.

Eligible patients received empiric treatment with vancomycin for suspected or confirmed respiratory infections from January through April 2019 (preimplementation cohort) and from October 2019 through January 2020 (postimplementation cohort).

The electronic health system software was modified to provide a best-practice advisory (BPA) prompt to the pharmacist upon order verification of vancomycin for patients with suspected or confirmed respiratory indications. Pharmacists were prompted to order a MRSA nasal swab if it was not already ordered by the provider.

We reviewed patient records to determine the time from vancomycin prescription to de-escalation. The secondary end point was incidence of acute kidney injury.

The study included 120 patients (preimplementation, n = 61; postimplementation, n = 59). Median time to de-escalation was significantly shorter for the postimplementation cohort: 76 hours (interquartile range [IQR], 52–109) versus 42 hours (IQR, 37–61; P = .002). Acute kidney injury occurred in 11 patients (18%) in the preimplementation cohort and in 3 patients (5%) in the postimplementation cohort (P = .01; number needed to treat, 8).

Implementation of a BPA notification for MRSA nasal screening helped decrease the time to de-escalation of vancomycin.
