The macro-social and environmental conditions in which people live, such as the level of a country’s development or inequality, are associated with brain-related disorders. However, the relationship between these systemic environmental factors and the brain remains unclear. We aimed to determine the association between the level of development and inequality of a country and the brain structure of healthy adults.

We conducted a cross-sectional study pooling brain imaging (T1-based) data from 145 magnetic resonance imaging (MRI) studies in 7,962 healthy adults (4,110 women) in 29 different countries. We used a meta-regression approach to relate the brain structure to the country’s level of development and inequality.

Higher human development was consistently associated with larger hippocampi and more expanded global cortical surface area, particularly in frontal areas. Increased inequality was most consistently associated with smaller hippocampal volume and thinner cortical thickness across the brain.

Our results suggest that the macro-economic conditions of a country are reflected in its inhabitants’ brains and may explain the different incidence of brain disorders across the world. The observed variability of brain structure in health across countries should be considered when developing tools in the field of personalized or precision medicine that are intended to be used across the world.

A consortium of five Spanish health technology assessment (HTA) agencies conducted the European Reference Networks Guidelines Programme for the development, appraisal, and implementation of clinical practice guidelines aiming to support clinical decision-making in the field of rare diseases (RDs). In response to this objective, methodologists and information specialists conducted systematic reviews (SRs). This study aims to explore the barriers/facilitators they encountered.

A survey was designed to elicit HTA agencies’ experience in developing SRs on RDs. Information was collected on the number of SRs conducted and the types of RDs and clinical questions addressed. In addition, they were asked to identify barriers and facilitators for each stage of the review (from the definition of PICO [population, intervention, comparator, outcome] components of the question to the issuing of recommendations). Finally, they were asked for process improvement suggestions. The survey was distributed by email and completed online. A thematic analysis was conducted to identify the issues identified at each stage of SR.

A total of 111 SRs were conducted on 35 RDs. Most clinical questions were about diagnosis and treatment. The main barriers identified were lack of MesH (Medical Subject Headings) terms associated with the conditions, non-representative abstracts and keywords, lack of relevant information in the body of the articles, and reported data not allowing for quantitative syntheses or recommendations to be made. Facilitating aspects included Orphanet’s specific source of RD documents and having expert clinicians in the working groups who were also involved in all steps of the SR.

Conducting SRs in the field of RDs is challenging. Authors of primary studies are encouraged to be more exhaustive in reporting the results. More research focused on the SR methodology in RDs is necessary to address their particular characteristics and obtain robust results. It is crucial to collaborate with reference networks to address RDs, where the evidence is scarce.

The assessment of technology in hospital settings is a crucial step towards ensuring the delivery of efficient, effective, and safe healthcare.

This study conducts a Hospital-Based Health Technology Assessment to evaluate the efficacy of a screening rapid test for mild Traumatic Brain Injury (mild TBI) utilizing blood biomarkers, specifically Glial Fibrillary Acidic Protein (GFAP) and Ubiquitin C-terminal Hydrolase L1 (UCH-L1). The assessment focuses on the clinical utility and performance characteristics of the proposed rapid test within a hospital setting.

The screening model was meticulously examined for its ability to accurately detect mild TBI, considering the sensitivity and specificity of GFAP and UCH-L1 as blood biomarkers. The study involved a thorough evaluation of the test’s diagnostic accuracy, comparing its outcomes with established standards for mild TBI diagnosis.

Results from the Hospital-Based Health Technology Assessment highlight the potential of the GFAP and UCH-L1 blood biomarker-based rapid test as an efficient screening tool for mild TBI within a hospital environment. The evidence results show that the test is highly sensitive (91 percent to 100 percent) for the prediction of acute traumatic intracranial lesions, which helps rule out injury when the result is negative. When used within 12 hours of injury in adult patients with mild TBI, this test holds promise in reducing the utilization of CT.

The findings contribute valuable insights into the feasibility and reliability of implementing this technology for timely and accurate identification of mild TBI, enhancing clinical decision making and patient care in hospital settings.

Corticosteroids are a key part of many cancer treatment regimens and neuropsychiatric side effects have long been recognised. Steroid-induced psychosis is a disorder classified under substance or medication-induced psychosis in the Diagnostic and Statistical Manual of Mental Disorder, 5th edition. Management strategies include treatment with antipsychotic medication and reducing corticosteroid dosage.

To describe the case of steroid induced psychosis in a patient with mediastinal lymphoma and provide a concise literature review.

Clinical case report and brief literature review.

27-year-old male with a diagnosis of Stage IV Primary Mediastinal Lymphoma according to the Ann Arbor classification was admitted to the Haematology ward for chemotherapy treatment (R-DA EPOCH). Two days after admission the patient developed acute psychotic symptoms consisting of thought block, kinaesthetic hallucinations, and delusions. Prior to admission, the patient had been on corticosteroid treatment for two months (up to 8mg/day of dexamethasone), with a significant dose increase (up to 200mg/day of prednisone) at the beginning of chemotherapy treatment two days prior to symptom development. The patient had no personal or family history of mental health issues, no substance misuse and had not received any psychopharmacological treatment prior to admission.

Medical evaluations including a cranial CT scan, an MRI, EEG, blood tests and lumber puncture were all within normal parameters, discounting organic or metastatic causes for the symptoms.

Considering a potential episode of steroid-induced psychosis, the patient was started on olanzapine at a dosage of 10mg per day. The patient exhibited a positive response, with symptoms alleviating within 24 hours of the initial dose. In terms of corticosteroid therapy, haematologists adjusted the prednisone regimen to 100mg per day, and due to the encouraging progress, the olanzapine dosage was subsequently reduced to 5mg per day.

This case underscores the importance of considering the possibility of steroid induced psychosis as a differential diagnosis specially in patients on high dose steroids presenting with psychotic symptoms. A multidisciplinary approach is crucial to ensure optimum treatment and care.

Chronic consumption of alcohol has clear deleterious effects on the nervous system. Among its less-recognized consequences are subacute and chronic alcohol-induced psychotic disorders. Lasègue, Garnier, Magnan, and Michaux provided exhaustive clinical descriptions of different presentations of subacute alcoholic delusional disorder, while Kraepelin, Allamagny, and Neveu defined the characteristics of chronic alcoholic hallucinatory psychosis. Both conditions are characterized by the occurrence of hallucinations and vivid dream-like content in their delusions, along with potential emotional detachment from the symptoms. Presently, both conditions are categorized under the generic term ‘Alcohol-Induced Psychotic Disorder,’ with limited available scientific literature.

Our goal is to bring attention to the existence of subacute and chronic alcohol-induced psychosis in individuals with long-term alcohol users.

Case report using clinical records and a non-systematic literature review.

A 63-year-old male, with a forty-year history of chronic alcoholism and no other prior mental health issues, was admitted in the emergency department. He conveyed vague delusional notions regarding his roommate and described vivid morning dreams in which he tried to communicate but couldn’t speak. This led him to believe his roommate harboured harmful intentions. Additionally, he mentioned that for the past two months, he had developed a telepathic connection with his sister and his deceased mother, with whom he felt he communicated without speaking. He described feeling strangement and anxiety concerning these experiences, which he firmly believed to be undeniably real. He reported being able to hear the voices of his mother and sister. He also described short-term memory problems dating back two years. He denied any other psychopathology and exhibited probable ideational and emotional impoverishment secondary to chronic alcohol consumption. Confirmation of the patient’s account was provided by his family members. The prescribed treatment included antipsychotic medication and a recommendation for alcohol abstinence.

Descriptions of chronic and subacute alcohol-induced psychoses are found in early psychiatric textbooks but have been omitted from contemporary classifications. While their incidence is low among chronic alcohol users, they represent a severe clinical entity. These disorders are usually distinguished by the presence of delusions and vivid hallucinations characterized by dream-like content. This distinct symptomatology aids in the accurate differentiation from other psychotic disorders and clinicians should be aware of their existence.

Long-acting injectable antipsychotics (LAIs) offer advantages for schizophrenic patients compared to oral antipsychotics: less frequent dosing, lower relapse rates, better adherence, and lower healthcare costs. LAIs include paliperidone, aripiprazole, olanzapine, risperidone, and zuclopenthixol. Paliperidone palmitate is the only antipsychotic with two formulations with an administration interval longer than one month (3-monthly and 6-monthly), which could be better for the patient and help ensure treatment continuity, especially in cases of limited access to the health care system.

To assess the satisfaction of patients under treatment with 6-month paliperidone palmitate compared to other long-acting injectable antipsychotics with a higher frequency of administration.

We analyzed the satisfaction level of a sample of patients receiving treatment with LAIs at the Mental Health Center of El Escorial. All patients had a diagnosis of schizophrenia or other psychotic disorders (according to DSM-5). Patients who met the inclusion criteria completed the Treatment Satisfaction Questionnaire for Medication (TSQM), a generic questionnaire of treatment satisfaction that measures four dimensions: side effects, treatment efficacy, comfort of use, and overall satisfaction. Other clinical and socio-demographic variables were collected, as well as the type of injectable, dose, and frequency of administration.

Data from approximately 30 patients will be analyzed and discussed later.

Less frequent administration of LAIs may result in greater patient satisfaction and be just as beneficial clinically. Treatment satisfaction is positively associated with an improvement in psychotic symptoms and seems to be related to better adherence.

Neuropsychiatric disorders can develop following a group A β-hemolytic streptococcal infection, through autoimmune inflammation of the nervous system. Sydenham’s chorea and PANDAS (Pediatric Autoimmune Neuropsychiatric Disorders Associated with Streptococcal Infection) are the two most well-known syndromes, primarily affecting children but rarely observed in adults.

Our aims are to contribute to the scientific understanding of adult PANDAS-like syndrome and provide a comprehensive literature review on the subject.

Case report using clinical records and a non-systematic literature review.

A 24-year-old female presented to the emergency department with profound emotional distress triggered by intrusive thoughts of existential dread, accompanied by compulsive praying. She reported that these symptoms had commenced five days earlier. Two days prior to the onset of her obsessions, she had experienced a high fever, odynophagia, cough, and chills and received an empirical diagnosis of tonsillitis following a physical examination. She was prescribed antibiotics with good response. She revealed that she had experienced two prior episodes of similar anxiety and obsessions when she was approximately seven years old.

She developed acute obsessive thoughts, including doubts about the meaning of her life, and engaged in compulsive prayer and seeking reassurance from relatives. Notably, there were no signs of affective, dissociative, or psychotic disorders during her admission to the ED or in the preceding months. She reported suffering from anxiety, insomnia, and loss of appetite in the past five days but did not express any suicidal ideation.

Physical examination indicated mild laryngeal erythema, and laboratory tests showed non-specific signs of infection with no further significant findings. Symptoms were alleviated within a week, aided by treatment with benzodiazepines (lorazepam 1 mg/8h), and she did not require further psychiatric counselling.

It is worth noting that adult patients can experience a PANDAS-like reaction after a streptococcal infection and may also undergo symptom relapse following new immunological challenges upon reinfection. The existence of a PANDAS spectrum has been postulated, encompassing various manifestations. Thus, when presented with acute obsessive symptoms, healthcare providers should consider this diagnosis, inquire about previous episodes, and conduct a comprehensive medical history and etiological assessment.

Lithium is considered the gold standard mood stabiliser for bipolar disorder, yet its use during pregnancy remains controversial, demanding careful consideration of potential risks and benefits. Classically, it has been associated with an increased risk in congenital heart defects, however, recent studies point towards a much lower absolute risk than was previously believed. Furthermore, discontinuation of lithium before or during pregnancy poses a high risk of destabilisation and lithium has been shown to reduce the risk of relapse both in pregnancy and in the postpartum period. Hence, treatment planning is of the upmost importance in this patient group and individual risk stratification should be undertaken for patients to make informed decisions about their treatment.

To describe the case of a patient with bipolar disorder who discontinued lithium treatment while attempting to conceive and subsequently presented with a manic episode and to expand the scientific knowledge on this topic.

Case report and brief literature review.

A 41-year-old patient with a diagnosis of bipolar disorder, previously on lithium 900mg/day, was admitted to the emergency department with symptoms suggestive of a manic episode. One month prior, the patient had discontinued treatment with lithium due to her desire to pursue pregnancy and interrupt treatment while trying to conceive. The patient had a history of postpartum psychosis followed by various depressive and manic episodes with psychotic symptoms, leading to a bipolar disorder diagnosis and commencing treatment with lithium. Her consultant psychiatrist had informed her of the individualised risks of interrupting treatment with lithium and had advised to continue treatment alongside frequent follow-up due to the high-risk of relapse. Despite her consultant’s recommendation, she decided to interrupt treatment and hence a personalised lithium tapering regime and advice to continue treatment with quetiapine 200mg/day was given.

During the ED stay, treatment with olanzapine was introduced which helped to stabilise her symptoms. Lithium levels were subtherapeutic (lithium serum level 0.11 mmol/L). Inpatient psychiatric admission was avoided due to rapid symptom improvement, strong social support in the community and her preference for ambulatory care. Lithium was gradually reintroduced and antipsychotic treatment was adjusted at follow up appointments, which ultimately led to the resolution of symptoms and stabilisation.

This case highlights the significance of considering continuing lithium treatment in bipolar disorder during pregnancy planning. Decisions about medication in pregnancy are multifaceted, making appropriate risk stratification imperative in order to inform individualised care plans to minimise the risk of relapse in these patients.

The purpose of this exploratory study is to examine the role of sociodemographic, clinical, and cognitive – both objective and subjective – factors in overall and in specific domains of psychosocial functioning, in patients with depression at different clinical states of the disease (remitted and non-remitted).

A sample of 325 patients with major depressive disorder, 117 in remission and 208 in non-remission, were assessed with a semi-structured interview collecting sociodemographic, clinical, cognitive (with neuropsychological tests and the Perceived Deficit Questionnaire), and functional (Functioning Assessment Short Test) characteristics. Backward regression models were conducted to determine associations of global and specific areas of functioning with independent factors, for both clinical states.

Residual depressive symptomatology and self-appraisal of executive competence were significantly associated with psychosocial functioning in remitted patients, in overall and some subdomains of functioning, particularly cognitive and interpersonal areas. While depressive symptoms, executive deficits and self-appraisal of executive function were significantly related to functional outcomes in non-remitted patients, both in overall functioning and in most of subdomains.

This study evidences the strong association of one’s appraisal of executive competence with psychosocial functioning, together with depressive symptoms, both in remitted and non-remitted patients with depression. Therefore, to achieve full recovery, clinical management of patients should tackle not only the relief of core depressive symptoms, but also the cognitive ones, both those that are objectified with neuropsychological tests and those that are reported by the patients themselves.

The coronavirus disease 2019 (COVID-19) has serious physiological and psychological consequences. The long-term (>12 weeks post-infection) impact of COVID-19 on mental health, specifically in older adults, is unclear. We longitudinally assessed the association of COVID-19 with depression symptomatology in community-dwelling older adults with metabolic syndrome within the framework of the PREDIMED-Plus cohort.

Participants (n = 5486) aged 55–75 years were included in this longitudinal cohort. COVID-19 status (positive/negative) determined by tests (e.g. polymerase chain reaction severe acute respiratory syndrome coronavirus 2, IgG) was confirmed via event adjudication (410 cases). Pre- and post-COVID-19 depressive symptomatology was ascertained from annual assessments conducted using a validated 21-item Spanish Beck Depression Inventory-II (BDI-II). Multivariable linear and logistic regression models assessed the association between COVID-19 and depression symptomatology.

COVID-19 in older adults was associated with higher post-COVID-19 BDI-II scores measured at a median (interquartile range) of 29 (15–40) weeks post-infection [fully adjusted β = 0.65 points, 95% confidence interval (CI) 0.15–1.15; p = 0.011]. This association was particularly prominent in women (β = 1.38 points, 95% CI 0.44–2.33, p = 0.004). COVID-19 was associated with 62% increased odds of elevated depression risk (BDI-II ≥ 14) post-COVID-19 when adjusted for confounders (odds ratio; 95% CI 1.13–2.30, p = 0.008).

COVID-19 was associated with long-term depression risk in older adults with overweight/obesity and metabolic syndrome, particularly in women. Thus, long-term evaluations of the impact of COVID-19 on mental health and preventive public health initiatives are warranted in older adults.

Omega-3 polyunsaturated fatty acids (PUFAs) have been studied in relation to mental illness. Among the most important omega 3 fatty acids, eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) stand out, both derived from alpha-linolenic acid. Both EPA and DHA are essential fatty acids. Consequently, mammals are not capable of synthesizing them and must incorporate them through the consumption of products such as fish oil. The interest about the role of omega 3 fatty acids for the treatment of patients with impulsiveness, hostility and aggressiveness is growing and originated from the finding of a low level of EPA and DHA in the central nervous system of these individuals.

To determine the evidence on the effectiveness of omega-3 acids in reducing severe symptoms in patients diagnosed with Borderline Personality Disorder.

A literature review was carried out in Epistemonikos, using the descriptors: “borderline personality disorder” AND “Omega-3”. 7 results are obtained. The results of a time limit of 10 years with meta-analyses and systematic reviews were filtered, obtaining 7 results and selecting 3 of them for their relevance to the PICO question. Subsequently, the search was repeated using the same descriptors and time limit in the Cochrane Library, NICE, and Pubmed; no selection was made by coincidence of those previously selected.

The first systematic review studied the effectiveness of omega-3 fatty acids in symptomatology associated with BPD, with differentiation of the domains of affective, impulsive and cognitive-perceptual symptoms. Within the meta-analysis, 5 randomized controlled trials (RCTs) were included that compared omega-3 fatty acids with placebo or any active comparator, four of these RCTs verified the effect of omega-3 acids in 137 patients with BPD or behavior related to the BPD.

The second systematic review, conducted in the Cochrane Collaboration, performed a meta-analysis of randomized comparisons of drug versus placebo. Twenty-seven trials testing first- and second-generation antipsychotics, mood stabilizers, antidepressants, and omega-3 fatty acids were included. For supplemental omega-3 fatty acids, significant effects were found in one study (n = 49 ) for reduction in suicidality (RR = 0.52, 95% CI 0.28 to 0.95) and depressive symptoms (RR = 0.48, 95% CI 0.28 to 0, 81).

Available data indicate that marine omega-3 fatty acids improve BPD symptoms, particularly impulsive behavioral dyscontrol and affective dysregulation, reducing depressive symptoms and suicidal tendencies. Marine omega-3 fatty acids could be considered as a complementary therapy for the improvement of severe symptoms associated with patients with BPD.
