Neurolupus as a manifestation of the first psychotic episode: case report.

Background: Systemic lupus erythematosus is a chronic mul-tisystemic autoimmune disease with diverse clinical manifestations. Women are the most vulnerable population and have the greatest neurological involvement with a higher risk of seizures. Neuropsychiatric manifestations occur in early stages of the disease and diagnosis since they can occur together with systemic manifestations or not. The frequency of neuropsychiatric manifestations in systemic lupus erythematosus has been described from 14 to 75%;being cognitive alterations one of the major symptoms to highlight. Which, in the same way can be accompanied by affective disorders such as depression and anxiety. Since psychosis, secondary to SLE, stands out for its low prevalence (10%), laboratory studies usually guide us towards a definitive diagnosis, being ribosomal P antibodies the ones that have been more specifically related to lupus psychosis. MRI is the test of choice and brain lesions are dominated by punctate white matter hyperintensities. In the following case report, we present a 20-year-old patient who had a history of diagnosed hepatic steatosis, MODY type diabetes and resection of the right ovary for mature teratoma of 9 years of evolution;but with no psychiatric history of importance at the time of her evaluation. However, she acutely presented a psychotic outbreak characterized by delusions of grandiosity and reference;as well as behavioral, cognitive, and affective alterations. For which she had to go to a 3rd level hospital during the period of health contingency in 2020. After a history of SARS-CoV-2 infection three months before her neuropsychiatric pathology, neurological symptoms secondary to COVID-19 infection were suspected, as well as isolated psychiatric pathology. Therefore, a study approach of the first psychotic outbreak was performed, diagnosing systemic lupus erythematosus with neuropsychiatric manifestations. Treatment was based on a bolus of methylprednisolone and antipsychotics;later modified by therapy with oral corticosteroids and depot antipsychotic. Conclusion: Systemic lupus erythematosus with neuropsychiatric manifestations is an infrequent presentation of the disease, because of the wide variation in its appearance, patients with psychiatric symptoms in a general hospital setting should be considered for extensive approaches. In the same way, having this knowledge of this case may broaden our knowledge about the complications of this rheumatologic pathology. And one of its most serious complications such as lupus psychosis to be able to make a better approach to the first psychotic outbreak in general hospitals, where the assessment of a specialist can be more complicated. (English) [ FROM AUTHOR] Antecedentes: El lupus eritematoso sistémico (LES) es una enfermedad auto inmunitaria crónica multisistémica con diversas manifestaciones clínicas. Siendo las mujeres la población vulnerable y con mayor afectación a nivel neurológico, al presentar mayor riesgo de convulsiones. Las manifestaciones neuropsiquiátricas ocurren en etapas tempranas de la enfermedad y del diagnóstico, ya que pueden presentarse junto con manifestaciones sistémicas o no. La frecuencia de manifestaciones neuropsiquiátricas en el lupus eritematoso sistémico se ha descrito del 14 al 75%, siendo las alteraciones cognitivas uno de los grandes síntomas a destacar1. La cual puede ir acompañada de trastornos afectivos de tipo depresión y ansiedad. Ya que la psicosis secundaria a LES se remarca por su baja prevalencia (10%)2, los estudios de laboratorio nos suelen orientar hacia el diagnóstico definitivo, siendo los anticuerpos ribosomales P los que se han relacionado más específicamente con la psicosis lúpica. La resonancia magnética es la prueba de elección y las lesiones cerebrales están dominadas por hiperintensidades de materia blanca en forma de punción3. En el siguiente reporte de caso, presentamos a una paciente de 20 años, la cual contaba con antecedentes de esteatosis hepática diagnosticado, diabetes tipo MODY y resección de ovario derecho por teratoma maduro de 9 años de evolución, pero sin antecedentes psiquiátricos de importancia para el momento de su valoración. Sin embargo, de forma aguda presentó un brote psicótico caracterizado por ideas delirantes de grandiosidad y referencia, así como alteraciones conductuales, cognitivas y afectivas. Por las que tuvieron que acudir a hospital de 3er nivel durante el periodo de contingencia sanitaria en el 2020. Tras el antecedente de presentar infección por SARS-CoV-2 tres meses antes de su patología neuropsiquiátricas. Se sospechó en síntomas neurológicos secundarios a infección por COVID-19, así como patología psiquiátrica aislada. Por lo que se realizó abordaje de estudio de primer brote psicótico, diagnosticándose lupus eritema-toso sistémico con manifestaciones neuropsiquiátricas. El tratamiento se basó en un bolo de metilprednisolona y antip-sicóticos, luego modificada por terapia con corticoesteroides orales y antipsicótico de depósito. Conclusión: El lupus eritematoso sistémico con manifestaciones neuropsiquiátricas es una presentación poco frecuente del padecimiento, por la amplia variación en este, los pacientes con síntomas psiquiátricos en contexto de hospital general deben de ser tomados en cuenta para abordajes extensos4. De la misma forma, el tener este conocimiento del caso podrá ampliar nuestro conocimiento sobre las complicaciones de esta patología reumatológica. Y una de sus complicaciones más graves como la psicosis lúpica para poder realizar un mejor abordaje del primer brote psicótico en hospitales generales, donde la valoración de un especialista puede ser más complicada para mejorar las condiciones médicas de estos pacientes.

Detection of Depression-Related Tweets in Mexico Using Crosslingual Schemes and Knowledge Distillation.

Mental health problems are one of the various ills that afflict the world's population. Early diagnosis and medical care are public health problems addressed from various perspectives. Among the mental illnesses that most afflict the population is depression; its early diagnosis is vitally important, as it can trigger more severe illnesses, such as suicidal ideation. Due to the lack of homogeneity in current diagnostic tools, the community has focused on using AI tools for opportune diagnosis. Unfortunately, there is a lack of data that allows the use of IA tools for the Spanish language. Our work has a cross-lingual scheme to address this issue, allowing us to identify Spanish and English texts. The experiments demonstrated the methodology's effectiveness with an F1-score of 0.95. With this methodology, we propose a method to solve a classification problem for depression tweets (or short texts) by reusing English language databases with insufficient data to generate a classification model, such as in the Spanish language. We also validated the information obtained with public data to analyze the behavior of depression in Mexico during the COVID-19 pandemic. Our results show that the use of these methodologies can serve as support, not only in the diagnosis of depression, but also in the construction of different language databases that allow the creation of more efficient diagnostic tools.

Abo Blood Group, Atherothrombotic Comorbidities, and COVID-19: A Case-Control Study of their Association in the Mexican Population.

BACKGROUND: COVID-19 has been associated with negative results in patients with A blood group and with a better evolution in O blood group individuals. AIM: Because the evidence regarding ABO blood groups and COVID was empirically not that clear in our country, we tested the association regarding COVID-19 and blood groups. MATERIAL AND METHODS: Adult patients were enrolled in this prospective, case-control, observational multicenter study. Patients with a confirmed diagnosis of COVID-19 were assigned to one of three groups based on the clinical presentation of the infection. Age, gender, ABO and Rh blood groups, body mass index, history of diabetes mellitus or high blood pressure, and smoking were recorded directly or from their clinical charts. ABO blood group was obtained from 5,000 blood donors (50% each gender). Atherothrombotic variables were compared with a nation-wide data collection. RESULTS: A total of 2,416 patients with COVID-19 were included (women:39.6%; men:60.4%). There were no significant differences between cases and controls in terms of age. O blood group was the most frequently found in healthy donors and COVID-19 patients, but this blood group was significantly higher in COVID-19 patients vs. healthy donors. ABO blood group was not associated with the final health status in COVID-19 patients. Obesity, diabetes mellitus, hypertension and smoking were significantly more frequent among COVID-19 patients. CONCLUSION: The proposed protective effect of the O blood group in COVID-19 patients could not be reproduced in the Mexican population while some atherothrombotic risk factors had a significant effect on the clinical evolution.
