ABSTRACT
Introducción: La enfermedad de Alzheimer (EA) es la principal causa de demencia, caracterizada por pérdida progresiva de memoria. Principal fuente de morbimortalidad en mayores de 65 años. En los últimos 20 años las muertes por EA han aumentado un 145% en el mundo. En Chile no hay estudios actuales que describan mortalidad por EA. El objetivo del presente trabajo es analizar y comparar las tasas de mortalidad (TM) por EA según sexo y grupo etario en Chile entre 2017-2021. Materiales y métodos: Estudio descriptivo, ecológico, sobre defunciones por EA entre 2017-2021 en Chile según sexo y grupo etario (n=10.223). Información obtenida de la base de datos del Departamento de Estadísticas e Información de Salud. Se realizó estadística descriptiva y cálculo de TM. No se requiere comité de ética. Resultados: La máxima TM del periodo fue 11,74 por cada 100.000 habitantes en 2021. El sexo femenino logró la mayor TM en este periodo. El grupo etario con mayor cantidad de defunciones fue el de 81 o más años con 76.6% (7.829) de las defunciones totales. Discusión: Se evidenció mantención y luego ascenso de TM por EA, podría deberse al aumento en la esperanza de vida. La mayor frecuencia de defunciones según sexo y edad, podría explicarse por mayor vulnerabilidad femenina a desarrollar EA y a cambios fisiológicos del envejecimiento. En conclusión, la TM por EA en Chile ha aumentado, probablemente secundario al aumento en la esperanza de vida. Se hace un llamado a continuar el estudio de la patología.
Introduction: Alzheimer's disease (AD) is the most common cause of dementia, characterized by progressive memory loss. It is the main source of morbidity and mortality in individuals over 65 years of age, with age being its primary non-modifiable risk factor. In the last 20 years, deaths from AD have increased by 145% worldwide. However, there are no current studies in Chile that describe mortality from AD. The objective of this study is to analyze and compare mortality rates due to AD according to sex and age group in the Chilean population during the years 2017-2021. Material and Methods: Descriptive, ecological study on deaths from AD between 2017-2021 in Chile, categorized by sex and age group (n=10,223). The database was obtained from the Department of Health Statistics and Information. Descriptive statistics and mortality rate calculations were performed. No ethics committee approval was required. Results: The maximum mortality rate (MR) was observed in 2021 with a value of 11.74 per 100,000 inhabitants. Women had the highest MR in this period. The age group with the highest number of deaths was 81 years or older, accounting for 76.6% (7,829) of the total deaths. Discussion: A plateau and subsequent increase in MR due to AD were observed, possibly explained by the increase in life expectancy. The higher frequency of deaths in women and specific age groups may be attributed to the higher vulnerability of women to developing AD and physiological changes related to aging. In conclusion, the MR from AD has increased in Chile, likely due to the rise in life expectancy, emphasizing the importance of continued research on this pathology.

Constant fishing industry innovations in response to consumer demands for novel, balanced healthy products exhibiting high nutritional value, as well as easy to prepare and ready to consume, have led to the emergence of new technologies. Among them, the development of products based on ground beef and fish mixtures are noteworthy. In this context, the purpose of this study was to develop products from different ground rainbow trout and tilapia fillet ratios, in the form of meatballs and nuggets, determining their proximate composition and physico-chemical, microbiological and toxicological characteristics. The average dry matter percentage of the developed products was 29.20±2.30%, while mineral content was 1.45±0.55%, lipid pulp content, 3.70±0.30% and crude pulp protein, 16.60±2.04%. Total psychotropic counts remained below 102 CFU/g, for standard counting on aerobic microorganism plates. Histamine and sulfur-based compounds were not detected in any of the prepared samples. The purpose of the work proposal was to develop foods and technologies that can serve as standards, allowing for simple handling products that apply ground meat mixtures from different fish species to maintain adequate nutritional indices after processing.(AU)

The transport of myo-inositol is the main mechanism for the maintenance of its high intracellular levels. We aimed to measure the mRNA and protein levels of myo-inositol cotransporters in the sciatic nerve (SN) and dorsal root ganglia (DRG) during experimental diabetes. Streptozotocin-induced (STZ; 4, 8, and 12 weeks; 65 mg/kg; ip) diabetic rats (DB) and age-matched euglycemic (E) rats were used for the analysis of mRNA and protein levels of sodium myo-inositol cotransporters 1, 2 (SMIT1, SMIT2) or H+/myo-inositol cotransporter (HMIT). There was a significant reduction in the mRNA levels for SMIT1 in the SN and DRG (by 36.9 and 31.0%) in the 4-week DB (DB4) group compared to the E group. SMIT2 was not expressed in SN. The mRNA level for SMIT2 was up-regulated only in the DRG in the DB4 group. On the other hand, the protein level of SMIT1 decreased by 42.5, 41.3, and 44.8% in the SN after 4, 8, and 12 weeks of diabetes, respectively. In addition, there was a decrease of 64.3 and 58.0% of HMIT in membrane and cytosolic fractions, respectively, in the SN of the DB4 group. In the DRG, there was an increase of 230 and 86.3% for SMIT1 and HMIT, respectively, in the DB12 group. The levels of the main inositol transporters, SMIT1 and HMIT, were greatly reduced in the SN but not in the DRG. SMIT-1 was selectively reduced in the sciatic nerve during experimental STZ-induced diabetes.

La recolección de datos se llevó a cabo a través de la revisión de la literatura existente sobre el tema y una entrevista semiestructurada a siete Terapeutas Ocupacionales, con experiencia en el área de estudio. La entrevista se centró en los siguientes temas: Componentes Ocupacionales evaluados por terapeutasocupacionales durante el proceso de Tratamiento y Rehabilitación, modelos y evaluaciones utilizadas por terapeutas ocupacionales y Componentes Ocupacionales que muestran mayor déficit. Los resultados de esta investigación revelaron que la mayoría de los terapeutas ocupacionales evalúan los componentes ocupacionales de rutina/hábitos, roles, volición, tiempo libre e historia laboral en la etapa de ingreso a Centros de Tratamiento y Rehabilitación. Los resultados también revelaron una carencia de modelos y evaluaciones adecuadas y específicas desde la Terapia Ocupacional en el tema de estudio. Este estudio concluye en que existe una carencia de homogeneidad en el lenguaje, instrumentos de evaluación y los modelos utilizados entre Terapeutas Ocupacionales en los distintos Centros de Tratamiento y Rehabilitación.
This research topic is framed within the field of occupational therapy and problematic drug abuse. The purpose of this qualitative study is to explore what occupational components occupational therapists assess in the process of treatment and rehabilitation of problematic drug abuse. The study also explores the models and assessments used during this process. The participants were selected out of the list of Treatment and Rehabilitation Centers, that provides Occupational Therapy intervention in an Intensive Outpatient Program. This list was obtained from thedatabase of the National Council for Narcotics Control (CONACE). Data was collected through literature review on the topic and semi-structured interviews with seven Occupational Therapists with experience in the field of Drug Addiction Treatment and Rehabilitation. Theinterviews focused on the following topics: occupational components that are assessed for occupational therapists during the process of Treatment and Rehabilitation, models or theoretical frameworks and assessments used during this process and occupational components most affected. The results revealed that the majority of occupational therapists evaluate the occupational components of routine / habits, roles, volition, leisure and work history at the stage of admission to Treatment and Rehabilitation Centers. In addition, the results reveal a lack of appropriate and specific models andassessments from the occupational therapy perspective within the field of drug abuse. This study concludes that there is a lack of homogeneity in language, assessment tools and models used between the Occupational Therapists working in the Treatment and Rehabilitation Centers.

Se describen los argumentos de 5 mujeres que utilizaron los servicios de partera en los últimos 5 años. Se utilizó una entrevista no estructurada de pregunta abierta. Se realizó análisis de contenido de categorías, se calcularon frecuencias y porcentajes. Los argumentos para optar por la atención de parteras entre otros son creencias de bienestar, preferencias de acompañamiento y experiencias con el sector salud, no ser afiliada al sector de salud, la influencia de amigos, la distancia del centro hospitalario, creencia de disminución del riesgo de enfermedad o muerte del recién nacido y las actividades y los procedimientos realizados por la partera a la madre. Los resultados sugieren involucrar, además del componente de género, un enfoque familiar y social en los servicios gineco obstétricos, e incluirlos en los currículos de Medicina y Enfermería para formar profesionales que respondan a las necesidades de esta población.

We present here the first results of Hg concentrations in three small shark species (Rhizoprionodon lalandei, R. porosus and Mustelus higmani) from the SE Brazilian coast. Mercury concentrations in R. lalandei ranged from 21.5 to 280.0 ng.g-1 dry weight (d.w.) (average 74.6 ng.g-1 d.w.; 17.9 ng.g-1 wet weight). In R. porosus, concentrations ranged from 7.6 to 90.5 ng.g-1 d.w. (average 42.2 ng.g-1 d.w., 9.4 ng.g-1 wet weight), whereas in M. higmani, concentrations ranged from 13.0 to 162.8 ng.g-1 d.w. (average 54.9 ng.g-1 d.w., 13.4 ng.g-1 wet weight). These concentration ranges are very low compared with values reported for other large shark species of the Southwestern Atlantic Ocean. There was a significant positive correlation between Hg concentrations and individual size, suggesting that biomagnification is occurring in these animals

El síndrome de Brugada es una de las principales causas de muerte súbita en adultos jóvenes sin enfermedad cardiaca estructural. Se trata de una enfermedad eléctrica cardiaca caracterizada por una mutación del gen SCN5A en el cromosoma 3, con transmisión autosómica dominante, que da lugar a una disfunción del canal de sodio. Esta se acompaña de un incremento en la Ito que implica pérdida del domo de la fase 2 del potencial de acción epicárdico. Esta alteración se asocia con una repolarización del tipo "Todo o nada" que origina una reentrada en fase dos. Dicha reentrada es la responsable de iniciar y perpetuar a las arritmias ventriculares (taquicardia o fibrilación ventricular) en estos pacientes. El patrón electrocardiográfico de bloqueo de rama derecha, elevación del ST de V1 a V3 y la presencia de muerte súbita o síncope son las características clínicas de este síndrome. En algunos enfermos es necesario realizar una prueba farmacológica con ajmalina o procainamida para evidenciar los cambios eléctricos.El único tratamiento disponible en la actualidad es el desfibrilador automático implantable (DAI). Con este aparato se reduce la mortalidad desde un 40 por ciento anual a un 0 por ciento a diez años. El tratamiento farmacológico no es útil.

Investigamos, durante um periodo de 4 anos (1982 a 1985), a ocorrencia de virus em secrecoes de nasofaringe coletadas de criancas com menos de 5 anos de idade apresentando quadro clinico de infeccao respiratoria aguda (IRA), residentes na cidade do Rio de Janeiro. Foram encontrados todos os virus conhecidos como associados a IRA, com excessao do virus influenza C e parainfluenza 1, 2 e 4. Virus foram isolados mais frequentemente de criancas internadas em salas de emergencia e enfermarias que daquelas atendidas em ambulatorio. Este fato esta claramente relacionado com a alta incidencia do virus sincicial respiratorio (RSV) nos casos mais severos de IRA. Especimes positivos para RSV aparecem principalmente durante o outono, nos 4 anos consecutivos, indicando uma ocorrencia sazonal. As salas de emergencias sao a melhor fonte de dados para vigilancia do RSV, onde um aumento no numero de casos positivos corresponde a um aumento no numero total de casos de IRA internados. Os adenovirus ocupam o segundo lugar entre os virus frequentemente isolados, sendo predominante os sorotipos 1, 2 e 7. Embora em menor numero os virus influenza e parainfluenza tipo 3 tambem sao encontrados. Virus influenza A foram isolados igualmente em criancas internadas em enfermarias, salas de emergencia e nos pacientes atendidos em...

A evidenciacao da presenca de acido ribonucleico (ARN) viral por eletroforese em gel de policrilamida (EGPA) foi comprovada como um metodo altamente sensivel e rapido para o diagnostico de infeccoes por rotavirus. Uma comparacao desta prova com a imunomicroscopia eletronica (IEM) e com o ensaio imunoenzimatico (EIE) no exame de 245 fezes de criancas com gastroenterite revelou completa concordancia entre os tres ensaios em 238 (97.14%) amostras. Entre 75 amostras positivas pelo menos em um dos tres ensaios, resultados negativos foram observados em 5 (6.48%) por EGPA, em 6 (6.76%) por EIE e em nenhum por IEM. Coloracao pela prata aumentou consideravelmente a sensibilidade do ensaio por EGPA.Concluimos que embora a IEM ainda seja a prova mais sensivel e rapida para o diagnostico de infeccoes por rotavirus, o ensaio por EGPA tem muitas vantagens em seu favor, sendo as principais as de nao necessitar equipamentos caros, de empregar exclusivamente reagentes quimicamente definidos, de identificar grupos e variantes virais e de detectar amostras que nao possuindo antigenos comuns a maioria dos rotavirus, nao sao revelaveis por ensaios sorologicos

Particulas morfologicamente identicas a rotavirus foram encontradas nas fezes de uma crianca de dois meses com gastroenterite. Analise do genoma viral por eletroforese em gel de poliacrilamida revelou 10 faixas (provavelmente 11 segmentos) de RNA, algumas das quais diferem em velocidade de migracao das observadas na grande maioria de rotavirus de hospedeiros humanos e de diversas especies de animais. O virus nao foi revelado por um ensaio imuno-enzimatico de alta sensibilidade, o que sugere a ausencia do antigeno de grupo que da reacoes cruzadas entre a maioria dos rotavirus. O virus descrito no presente trabalho foi o unico com tal comportamento entre 230 amostras analisadas por nos desde 1979. A relevancia de existencia de rotavirus nao relacionados antigenicamente a outros membros do grupo e discutida
