RESUMO
ABSTRACT Objectives: Psychiatric diagnosis is based on clinical manifestations, resulting from patients' internal state, their life situation, the evolution of their condition and the response to our interventions. There are currently few objective data which help to establish the diagnosis which is why this is based on diagnostic criteria such as the Diagnostic and Statistical Manual of Mental Disorders (DSM). The DSM defines entities by their diagnostic stability, however there are several causes of variability as categorised by Spritzer et al. (1987): subjects variance (changing in patients), occasions variance (different episodes), information variance (new information) and observation variance (different interpretations). This paper aims to determine the diagnostic stability of patients with Psychotic Disorders among patients readmitted to our Psychiatric Unit. Methods: Retrospective analysis of the diagnoses of patients with Psychotic Disorders who had been readmitted to our unit. We analysed data from the last 12 years - 5422 admission episodes with 507 patients with a relevant diagnosis in this period. Results: Psychiatric diagnosis does evolve over time, nevertheless some diagnostic groups show a relatively significant stability over time - Bipolar Disorder and Schizophrenia with 69% and 77% stability, respectively. Diagnosis such as Depressive Psychosis and Drug-induced psychosis show a significantly lower stability (8% and 21%, respectively). Conclusions: Knowing our own reality can make us aware that a cross-sectional view of patients can be insufficient and only time can determine a clear diagnosis. This study may help us to understand how psychotic disorders evolve.
RESUMEN Objetivos: El diagnóstico psiquiátrico se basa en las manifestaciones clínicas, consecuencia del estado interno del paciente, de su situación vivencial, de la evolución de su enfermedad y de la respuesta a nuestras intervenciones. Actualmente, existen pocos datos objetivos que ayudan a establecer el diagnóstico por lo que éste se basa en criterios diagnósticos como el Manual Diagnóstico y Estadístico de los Trastornos Mentales (DSM). La DSM define diagnósticos por su estabilidad, sin embargo, existen varias causas de variabilidad caracterizadas por Spritzer et al. (1987): variación en el sujeto (cambio en el paciente), variación ocasional (diferentes episodios), variación en la información (nueva información) y variación en la observación (diferentes interpretaciones). Este trabajo pretende evaluar la estabilidad diagnóstica de los pacientes con Trastornos Psicóticos reinternados en nuestro internamiento psiquiátrico. Métodos: Análisis retrospectivo de los diagnósticos de los pacientes con Trastornos Psicóticos con reingresos en nuestro servicio. Se analizaron datos de los últimos 12 anos - 5422 admisiones con 507 pacientes con diagnóstico de interés en ese período. Resultados: El diagnóstico psiquiátrico se altera con el tiempo, sin embargo, algunos grupos revelan una mayor estabilidad a lo largo del tiempo - Perturbación Afectiva Bipolar y Esquizofrenia con el 69% y el 77%, respectivamente. Los diagnósticos como la depresión psicótica y la psicosis tóxica, revelan una estabilidad significativamente menor (8% y 21% respectivamente). Conclusiones: Conocer nuestra realidad nos hace conscientes de que una mirada transversal a los enfermos puede ser insuficiente y sólo el tiempo puede determinar un diagnóstico claro. Este trabajo puede ayudarnos a entender cómo evolucionan las enfermedades psicóticas.
RESUMO
It was developed a material to act as an antimicrobial and antiparasitic agent through a modification reaction in the gum structure extracted from the plant Sterculia striata. This material was characterized, the oxidant activity was evaluated and the antimicrobial activity against Candida albicans, Escherichia coli, Pseudomonas aeruginosa, Salmonella Typhimurium and Klebsiella pneumoniae was investigated, in addition to the effect against Leishmania amazonensis, testing its acute toxicity and its cytotoxicity in human cells. Characterization techniques proved the success of chemical modification. The modification led to an increase in antioxidant activity, with excellent antibacterial activity, reaching almost 100% inhibition for P. aeruginosa and S. Typhimurium, and inhibitory effect above 70% against L. amazonensis, with an affinity far superior to the parasite than macrophages. The derivative showed no acute toxicity, it was non-hemolytic, increased cell viability in macrophages and fibroblasts, and stimulated cell proliferation of keratinocytes, thus being a strong candidate to be used as an antimicrobial and antiparasitic agent in biomedical applications.

BACKGROUND: Women are reported to have greater mortality after stroke than men, but the reasons are uncertain. We examined sex differences in mortality at 1 and 5 years after stroke and identified factors contributing to these differences. METHODS AND RESULTS: Individual participant data for incident strokes were obtained from 13 population-based incidence studies conducted in Europe, Australasia, South America, and the Caribbean between 1987 and 2013. Data on sociodemographics, stroke-related factors, prestroke health, and 1- and 5-year survival were obtained. Poisson modeling was used to estimate the mortality rate ratio (MRR) for women compared with men at 1 year (13 studies) and 5 years (8 studies) after stroke. Study-specific adjusted MRRs were pooled to create a summary estimate using random-effects meta-analysis. Overall, 16 957 participants with first-ever stroke followed up at 1 year and 13 216 followed up to 5 years were included. Crude pooled mortality was greater for women than men at 1 year (MRR 1.35; 95% confidence interval, 1.24-1.47) and 5 years (MRR 1.24; 95% confidence interval, 1.12-1.38). However, these pooled sex differences were reversed after adjustment for confounding factors (1 year MRR, 0.81; 95% confidence interval, 0.72-0.92 and 5-year MRR, 0.76; 95% confidence interval, 0.65-0.89). Confounding factors included age, prestroke functional limitations, stroke severity, and history of atrial fibrillation. CONCLUSIONS: Greater mortality in women is mostly because of age but also stroke severity, atrial fibrillation, and prestroke functional limitations. Lower survival after stroke among the elderly is inevitable, but there may be opportunities for intervention, including better access to evidence-based care for cardiovascular and general health.
