ABSTRACT

BACKGROUND: Fabry nephropathy is a consequence of the deposition of globotriaosylceramide, caused by deficient GLA enzyme activity in all types of kidney cells. These deposits are perceived as damage signals leading to activation of inflammation resulting in renal fibrosis. There are few studies related to immunophenotype characterization of the renal infiltrate in kidneys in patients with Fabry disease and its relationship to mechanisms of fibrosis. This work aims to quantify TGF-ß1 and active caspase 3 expression and to analyze the profile of cells in inflammatory infiltration in kidney biopsies from Fabry naïve-patients, and to investigate correlations with clinical parameters. METHODS: Renal biopsies from 15 treatment-naïve Fabry patients were included in this study. Immunostaining was performed to analyze active caspase 3, TGF-ß1, TNF-α, CD3, CD20, CD68 and CD163. Clinical data were retrospectively gathered at time of kidney biopsy. RESULTS: Our results suggest the production of TNFα and TGFß1 by tubular cells, in Fabry patients. Active caspase 3 staining revealed that tubular cells are in apoptosis, and apoptotic levels correlated with clinical signs of chronic kidney disease, proteinuria, and inversely with glomerular filtration rate. The cell infiltrates consisted of macrophages, T and B cells. CD163 macrophages were found in biopsy specimens and their number correlates with TGFß1 and active caspase 3 tubular expression. CONCLUSIONS: These results suggest that CD163+ cells could be relevant mediators of fibrosis in Fabry nephropathy, playing a role in the induction of TGFß1 and apoptotic cell death by tubular cells. These cells may represent a new player in the pathogenic mechanisms of Fabry nephropathy.

ABSTRACT

Studies have reported conflicting results on the association between handgrip strength (HGS) and blood pressure during childhood and adolescence. High multicollinearity involving somatic components that influence both HGS and blood pressure might be an important source of bias. This study sought to investigate the independent effects of HGS and muscle mass on blood pressure levels in children and adolescents. Muscle mass and fat mass (Multifrequency Electrical Bioimpedance) and systolic (SBP) and diastolic (DBP) blood pressure (Automatic oscillometric device) were assessed in 833 volunteers aged 6-18 years, of both sexes. Handgrip strength-for-age quartiles were calculated and participants were assigned to groups by HGS quartiles. Analysis of covariance was conducted to address the linear association between HGS and SBP adjusted for height, muscle mass, and fat mass. To test for linear trend, contrast analysis was conducted. Partial eta-squared was used to confirm or rule out a small significant effect of the independent variables on SBP. The effect size of HGS on SBP was not significant in both sexes. In girls, 1.7% of the between-groups variance in SBP was accounted for by muscle mass (P = 0.016). In boys, 2.3% and 1.8% of the between-groups variance in SBP was accounted for by muscle mass (P = 0.001) and height (P = 0.005), respectively. In conclusion, children with a more advanced physical maturity for their age, that is, who are taller, stronger, and have greater fat-free mass, may be nearly reaching the physiological parameters of adulthood, and consequently have higher systolic blood pressure.

ABSTRACT

Gaucher disease (GD) is caused by biallelic pathogenic variants in the acid ß-glucosidase gene (GBA1), leading to a deficiency in the ß-glucocerebrosidase (GCase) enzyme activity resulting in the intracellular accumulation of sphingolipids. Skeletal alterations are one of the most disabling features in GD patients. Although both defective bone formation and increased bone resorption due to osteoblast and osteoclast dysfunction contribute to GD bone pathology, the molecular bases are not fully understood, and bone disease is not completely resolved with currently available specific therapies. For this reason, using editing technology, our group has developed a reliable, isogenic, and easy-to-handle cellular model of GD monocytes (GBAKO-THP1) to facilitate GD pathophysiology studies and high-throughput drug screenings. In this work, we further characterized the model showing an increase in proinflammatory cytokines (Interleukin-1ß and Tumor Necrosis Factor-α) release and activation of osteoclastogenesis. Furthermore, our data suggest that GD monocytes would display an increased osteoclastogenic potential, independent of their interaction with the GD microenvironment or other GD cells. Both proinflammatory cytokine production and osteoclastogenesis were restored at least, in part, by treating cells with the recombinant human GCase, a substrate synthase inhibitor, a pharmacological chaperone, and an anti-inflammatory compound. Besides confirming that this model would be suitable to perform high-throughput screening of therapeutic molecules that act via different mechanisms and on different phenotypic features, our data provided insights into the pathogenic cascade, leading to osteoclastogenesis exacerbation and its contribution to bone pathology in GD.

ABSTRACT

BACKGROUND: Sedentary behavior has been associated with several cardiometabolic risk factors during childhood. However, little is known about the impact of sedentary behavior on the health and eating habits of physically active children and adolescents. OBJECTIVE: To evaluate the association between sedentary behavior and cardiometabolic risk factors and eating habits in physically active children and adolescents. METHODS: This cross-sectional study was conducted, including 516 physically active children and adolescents (10 to 18 years old; both sexes) enrolled in the social project "Estação Conhecimento-Vale" were evaluated. Biochemical and lifestyle variables (questionnaire) were collected. Sedentary behavior was determined indirectly (questionnaire), by using sitting time ≥ 3 hours per day as a cutoff point. A p-value < 0.05 was considered statistically significant for all tests. RESULTS: Sedentary behavior was not associated with overweight/obesity (odds ratio = 0.72 [95% confidence interval (CI): 0.325-1.389]), hypertriglyceridemia (odds ratio = 0.63 [95% CI: 0.306-1.297]), low HDL cholesterol (odds ratio = 0.57 [95% CI: 0.323-1.019]), or high non-HDL cholesterol (odds ratio = 0.63 [95% CI: 0.283-1.389]). However, children and adolescents with sedentary behavior were more likely to regularly consume food in front of the television (odds ratio = 1.96 [95% CI: 1.114-3.456]) and to consume at least one ultra-processed food per day (odds ratio = 2.42 [95% CI: 1.381-4.241]). In addition, they were less likely to consume fruit regularly (odds ratio = 0.52 [95% CI: 0.278-0.967]). CONCLUSION: There was no association between sedentary behavior and cardiometabolic risk factors in physically active children and adolescents. However, sedentary behavior was associated with inadequate eating habits. Thus, we may suggest that the regular engagement in physical activity may attenuate the deleterious effects of sedentary behavior on the cardiometabolic parameters of children and adolescents.


FUNDAMENTO: O comportamento sedentário tem sido associado a diversos fatores de risco cardiometabólicos durante a infância. No entanto, pouco se sabe sobre o impacto do comportamento sedentário na saúde e nos hábitos alimentares de crianças e adolescentes fisicamente ativos. OBJETIVO: Avaliar a associação entre comportamento sedentário e fatores de risco cardiometabólicos e hábitos alimentares em crianças e adolescentes fisicamente ativos. MÉTODOS: Esse estudo transversal avaliou 516 crianças e adolescentes (10 a 18 anos; ambos os sexos) fisicamente ativos integrados no projeto social "Estação Conhecimento-Vale". O comportamento sedentário foi determinado de maneira indireta (questionário), utilizando como ponto de corte o tempo sentado ≥ 3 h/dia. Foram estatisticamente significantes as análises com p-valor < 0,05. RESULTADOS: O comportamento sedentário não foi associado ao excesso de peso (odds ratio = 0,72 [intervalo de confiança (IC) de 95%: 0,325-1,389]), hipertrigliceridemia ( odds ratio = 0,63 [IC95%: 0,306-1,297]), HDL colesterol baixo ( odds ratio = 0,57 [IC95%: 0,323-1,019]) e HDL não colesterol alto ( odds ratio = 0,63 [IC95%: 0,283-1,389]). Contudo, crianças e adolescentes que adotavam comportamento sedentário apresentaram maior chance de consumir regularmente alimentos em frente à televisão ( odds ratio =1,96 [IC95%: 1,114-3,456]) e de consumir pelo menos um alimento ultraprocessado por dia ( odds ratio =2,42 [IC95%: 1,381-4,241]). Além disso, apresentaram menor chance de consumir frutas regularmente (OR=0,52 [IC95%: 0,278-0,967]). CONCLUSÃO: Não houve associação entre comportamento sedentário e fatores de risco cardiometabólicos em crianças e adolescentes fisicamente ativos. Contudo, o comportamento sedentário foi associado a hábitos alimentares inadequados. Dessa forma, podemos sugerir que a prática regular de atividade física pode atenuar os efeitos deletérios do comportamento sedentário nos parâmetros cardiometabólicos de crianças e adolescentes.

ABSTRACT

The electrospun nanosystems containing poly(3-hydroxybutyrate-co-3-hydroxyvalerate) (PHBV) and 1 wt% Fe doped ZnO nanoparticles (NPs) (with the content of dopant in the range of 0-1 wt% Fe) deposited onto polylactic acid (PLA) film were prepared for food packaging application. They were investigated by scanning electron microscopy (SEM), energy dispersive X-ray (EDX), Fourier transform infrared spectroscopy (FT-IR), X-ray diffraction (XRD), antimicrobial analysis, and X-ray photoelectron spectrometry (XPS) techniques. Migration studies conducted in acetic acid 3% (wt/wt) and ethanol 10% (v/v) food simulants as well as by the use of treated ashes with 3% HNO3 solution reveal that the migration of Zn and Fe falls into the specific limits imposed by the legislation in force. Results indicated that the PLA/PHBV/ZnO:Fex electrospun nanosystems exhibit excellent antibacterial activity against the Pseudomonas aeruginosa (ATCC-27853) due to the generation of a larger amount of perhydroxyl (˙OOH) radicals as assessed using electron paramagnetic resonance (EPR) spectroscopy coupled with a spin trapping method.

ABSTRACT

BACKGROUND: Kidney is one of the main target organs in Fabry disease, a lysosomal X-linked genetic disorder. Renal involvement is characterized by proteinuria and progressive chronic kidney disease leading to end-stage renal disease. Pathogenic mechanisms in the progression of renal damage in Fabry disease are not thoroughly known yet. The lysosomal Gb3 deposition is the first step of complex pathological pathways resulting in renal sclerosis/fibrosis. Our hypothesis is that Fabry disease associated cellular alterations in tubular cells induce the production of TGF-ß1, which mediate transdifferentiation of renal cells into myofibroblasts resulting in fibrosis of renal tissue. OBJECTIVES: The aim of this work is to study the mechanisms leading to fibrosis in kidney from human Fabry patients. METHODS: Fifteen renal biopsies from naïve Fabry patients were included. Histological and immunohistochemical analysis was carried out. RESULTS: Positive staining for TGF-ß1 was found in tubular epithelial cells in biopsies from Fabry patients. Apoptosis was determined by active caspase 3 staining in tubular and mesangial glomerular cells. Due to TGF-ß1 is the main profibrotic cytokine and induces accumulation of myofibroblasts, we performed a study for its marker α-smooth muscle actin (α-SMA). This study revealed expression of α-SMA on pericytes surrounding peritubular capillaries, smooth muscle cells of blood vessels, mesangial cells and periglomerular zone. TGF-ß1 is produced mainly by tubular cells in Fabry kidney biopsies probably inducing cellular trans-differentiation of renal cells into myofibroblasts. A positive staining for a marker of myofibroblasts was present, affirming the presence of those profibrotic cells. CONCLUSIONS: These results show for the first time that TGF-ß1 is expressed in human renal tissue from Fabry patients, and that this profibrotic cytokine is mainly produced by proximal tubular cells. In addition both, peritubular interstitium and glomeruli, presented cells positive for myofibroblasts markers.

ABSTRACT

OBJECTIVE: Estimate the prevalence of benzodiazepine use by adult women at a Family Health Unit and identify the risk factors associated with this usage. METHOD: Quantitative cross-sectional study that employed secondary data developed at a Family Health Unit in the state of São Paulo, Brazil. We collected the data from the following sources: medical charts, registration forms, and the archive of prescriptions from the pharmacy at the referred health unit. We employed the chi-squared, Student's t, and Mann-Whitney tests, as well as logistic regression analysis. RESULTS: We identified 81 benzodiazepine users amongst 1,094 adult women (7.4%). Regarding the risk factors, the comparison between the groups of benzodiazepine users (n = 64) and non-users (n = 70) showed that having a chronic disease and using other psychotropic drugs were significantly associated with the use of benzodiazepines. CONCLUSION: The prevalence found was lower than the described in previous studies performed in Primary Health Units. The group that must receive greater attention regarding the consumption of benzodiazepines is that of middle-aged women or older, with low education levels, and chronic illnesses.

ABSTRACT

Abstract Background: Demand for naturally enriched foods is increasing worldwide. Animal nutrition allows incorporating nutraceutical molecules into milk. These molecules are intended for improving human health. Objective: To evaluate the effects of pelleting and monensin addition to the diet on intake, digestibility of dry matter (DM) and nutrients, milk yield and composition, and fatty acids (FA) profile in cows kept on pasture and supplemented with concentrate containing ground flaxseed (GF). Methods: Four Holstein cows were assigned to the following treatments: 1) concentrate with GF; 2) GF + 32.93 mg/Kg monensin (GFM); 3) GF pelleted (GFP); 4) GF pelleted + 32.93 mg/Kg monensin (FMP). Results: Treatments did not show effects on digestibility of dry matter (DM) and nutrients or feed intake, with the exception of ether extract intake, which was reduced by 28% with pelleting. Addition of monensin increased the conjugated linoleic acid (CLA) concentration by 47%. Pelleting increased the concentrations of CLA (70%), polyunsaturated FA (PUFA; 25%), and monounsaturated FA (MUFA; 16%), and reduced the concentrations of steric acid (C18) in 19% and total saturated FA (SFA; 14%). Conclusion: Pelleting and monensin does not alter feed intake and digestibility of DM and nutrients. Pelleting of concentrate feed containing flaxseed improves milk FA quality.


Resumen Antecedentes: La demanda por alimentos naturalmente enriquecidos se ha venido incrementado en todo el mundo. A través de la nutrición animal es posible incorporar moléculas nutracéuticas en la leche. El uso de estas moléculas pretende mejorar la salud humana. Objetivo: Evaluar los efectos de la peletización y la monensina sobre la ingesta, digestibilidad de la materia seca (DM) y nutrientes, producción de leche, composición y perfil de ácidos grasos (FA) en leche de vacas en pastoreo que consumen alimento concentrado formulado con linaza molida (GF). Métodos: Cuatro vacas Holstein fueron distribuidas en los siguientes tratamientos: 1) ración conteniendo GF; 2) GF + 32,93 mg/Kg de monensina (GFM); 3) GF en pellets (GFP); 4) GF en pellets + 32,93 mg/Kg de monensina (FMP). Resultados: Los tratamientos no mostraron efectos en el consumo y digestibilidad de la DM y nutrientes, excepto por el consumo de extracto etéreo, con una reducción del 28% en las raciones peletizadas. La monensina incrementó la concentración de ácido linoleico conjugado (CLA) en 47%. La peletización aumentó el contenido de CLA (70%), FA poliinsaturados (PUFA; 25%) y FA monoinsaturados (16%); y redujo las concentraciones de C18 en 19%, y FA saturados total en 14%. Conclusión: El peletizado y la monensina no alteran la ingesta de alimento ni la digestibilidad de la DM y nutrientes. El proceso de peletizado aplicado a concentrados que contienen linaza mejora la calidad de los ácidos grasos de la leche.


Resumo Antecedentes: A procura por alimentos naturalmente enriquecidos tem aumentado por parte dos consumidores. Através da nutrição animal é possível incorporar ao leite moléculas nutracêuticas, essas moléculas são conhecidas por melhorarem a saúde humana. Objetivo: Avaliar os efeitos da peletização e monensina sobre o consumo, digestibilidade da matéria seca (DM) e nutrientes, produção de leite, composição e perfil de ácidos graxos (FA) no leite de vacas em pastejo e suplementadas com concentrado contendo linhaça moída (GF). Métodos: Quatro vacas Holandesas foram distribuídas nos tratamentos: 1) concentrado contendo GF; 2) GF + 32,93 mg/Kg de monensina (GFM); 3) GF peletizado (GFP); 4) GF peletizado + 32,93 mg/Kg de monensina (FMP). Resultados: Os tratamentos não apresentaram efeitos sobre consumo e digestibilidade da DM e dos nutrientes, exceto para o consumo de extrato etéreo, com redução de 28% com a peletização do concentrado. A adição de monensina aumentou a concentração de ácido linoleico conjugado (CLA) em 47%. A peletização aumentou os teores de CLA (70%), FA poli-insaturados (25%) e FA monoinsaturados (16%); e reduziu as concentrações de C18 em 19% e AG saturados totais em 14%. Conclusão: Peletização e monensina não alteram o consumo e digestibilidade da DM e dos nutrientes. O processo de peletização aplicado em concentrados contendo linhaça melhora a qualidade dos FA do leite.

ABSTRACT

Resumo Sintomas de desconexão inter-hemisférica após lesão cerebral adquirida são pouco usuais na prática clínica atualmente. Os sintomas costumam diminuir espontaneamente e podem incluir anomia táctil, agrafia à esquerda e sinais de competição entre os hemisférios, como o "sinal da mão alienígena". Este trabalho tem por objetivo apresentar um relato de caso clínico de paciente de 33 anos, que evoluiu com sintomas de desconexão inter-hemisférica e alterações de funções executivas, após intervenção cirúrgica para remoção de tumor em região da hipófise, além de avaliar a aplicabilidade de programa de reabilitação neuropsicológica para as queixas cognitivas apresentadas. O paciente foi avaliado com instrumentos neuropsicológicos padronizados antes de iniciar a reabilitação e próximo à alta do tratamento. O estudo de caso foi realizado a partir da análise de dados de intervenção e evolução clínica do paciente em prontuário institucional (resultados de exame de avaliação neuropsicológica e registros de intervenções em sessões de reabilitação). Ao longo de sua evolução, o paciente apresentou melhora dos sintomas cognitivos e demonstrou benefício com os treinos e estratégias utilizados para sua adaptação, bem como para retomar o trabalho e outras atividades prévias. Destaca-se ainda a importância de se realizar mais estudos de intervenções neuropsicológicas para indivíduos com déficits cognitivos.


Resumen Los síntomas de desconexión interhemisférica después de una lesión cerebral adquirida son inusuales en la práctica clínica actual. Los síntomas generalmente disminuyen de forma espontánea y pueden incluir anomia táctil, agrafía izquierda y signos de la competencia entre los hemisférios. Este estudio tiene como objetivo presentar un caso clínico de un paciente de 33 años, que desarrollaron síntomas de desconexión interhemisférica después de la cirugía para la extirpación del tumor en la región pituitaria y alteraciones en la función ejecutiva y evaluar la aplicabilidad del programa de rehabilitación neuropsicológica para las quejas cognitivas. El paciente fue evaluado con instrumentos neuropsicológicas estandarizadas antes de comenzar la rehabilitación y cerca del máximo tratamiento. El estudio de caso se llevó a cabo a partir del análisis de datos de intervención y el desarrollo clínico del paciente registro médico institucional (resultados de los exámenes de evaluación neuropsicológica y las intervenciones en los registros de las sesiones de rehabilitación). A lo largo de su evolución, el paciente mostró una mejoría en los síntomas cognitivos y demostró un beneficio con la formación y las estrategias utilizadas para adaptarse y para reanudar el trabajo y otras actividades anteriores. También pone de relieve la importancia de llevar a cabo más estudios de intervenciones neuropsicológicas para las personas con déficits cognitivos.


Abstract Symptoms of interhemispheric disconnection after acquired brain injury are unusual in the current clinical practice. Symptoms usually diminish spontaneously and may include tactile anomia, agraphia and left signs of competition between the hemispheres, such as "alien hand sign". This work presents a case report of a 33 year old patient who developed symptoms of interhemispheric disconnection and executive function deficits after surgery for removal of a tumor in the pituitary region, as well as the evaluation of the applicability of the neuropsychological rehabilitation program for the cognitive complaints presented. The patient was evaluated with standardized neuropsychological instruments before starting rehabilitation and again close to the discharge from treatment. The case study was conducted by analyzing intervention data and the clinical outcome of the patient in the institutional records (results of neuropsychological evaluation examination and records of interventions in rehabilitation sessions). Throughout his evolution, the patient showed improvement in cognitive symptoms and demonstrated benefits from the training and strategies used for his adaptation and return to work and other previous activities. The study highlights the importance of conducting more studies of neuropsychological interventions for individuals with cognitive deficits.

ABSTRACT

La higiene de las manos es una de las principales medidas de control de las infecciones. Este estudio tuvo como objetivo comparar las tasas de adherencia a la higiene de las manos obtenidos por métodos de observación directa y la tasa autorreportada en una unidad de cuidados intensivos. Estudio transversal realizado en un hospital universitario, entre septiembre y diciembre de 2013. Los datos fueron recolectados a través de la observación directa del personal médico y de enfermería, y la aplicación de un cuestionario estructurado para identificación de las tasas de adhesión autorreportadas. Se realizaron análisis descriptivos y univariantes. El proyecto fue aprobado por el Comité de Ética. Se obtuvo un total de 1935 oportunidades para la higiene de las manos. La tasa de adhesión autorreportada fue de 87,9%, mientras que la tasa observada fue del 19,0% (p <0,001). La higiene de las manos simple fue referido como preferido por 70,2% de los profesionales de la salud, seguido de 12,3% de fricción con solución alcohólica antiséptica y 17,5% por ambos (higiene de las manos simple seguida de fricción con solución alcohólica antiséptica), y dichas tasas fueron similares en la adhesión autorreportadas y la observación directa. Las tasas de adhesión autorreportadas a la higiene de manos fueron sobreestimadas y las tasas obtenidas por observación directa fueron bajas, aunque no distinta de la escena mundial, reafirmando la necesidad de estrategias de implementación continua para la mejora de estas (AU)

Objetivou-se comparar as taxas de adesão à HM obtidas por métodos de observação direta e taxa autorreportada em uma unidade de terapia intensiva. Tratou-se de um estudo transversal, realizado em um hospital universitário entre setembro e dezembro de 2013. Os dados foram coletados por meio da observação direta dos médicos e equipe de enfermagem e aplicação de um questionário estruturado para identificar a taxa de adesão autorreportada e sua percepção sobre tal procedimento. Foram realizadas análises descritiva e univariada. Foram acompanhadas 1.935 oportunidades para HM. A taxa de adesão autorreportada foi de 87,9% e a taxa observada 19,0% (p<0,001). A HM simples foi referida como preferida por 70,2% dos profissionais de saúde, seguido de 12,3% para fricção antisséptica e 17,5% para ambas (HM simples seguida de fricção antisséptica), sendo tais taxas semelhantes para a taxa autorreportada e observação direta. As taxas de adesão à HM autorreportadas foram superestimadas e as taxas obtidas pela observação direta foram baixas, embora não distintas do panorama mundial, reafirmando a necessidade de implementação de estratégias contínuas para melhoria destas (AU)


Hand hygiene is one of the main measure to control infections. This study aimed to compare hand hygiene adherence rates in an intensive care unit obtained through direct observation and self-reported compliance. This cross-sectional study was conducted in a university hospital between September and December of 2013. Data were collected through direct observation of healthcare workers from medical and nursing staff and the application of a structured questionnaire to identify self-reported compliance rates. Descriptive and univariate analysis were performed. A total of 1,935 opportunities for practicing hand hygiene was obtained. The self-reported hand hygiene adherence rate was 87.9% and observed adherence was 19.0% (p<0.001). Simple hand hygiene was reported as preferred by 70.2% of healthcare workers, followed by 12.3% for hand rubbing with alcohol and 17.5% for both (simple hand hygiene followed by hand rubbing with alcohol), such rates being similar for self-reported and observed rates. The self-reported hand hygiene rates were overestimated and the rates obtained through direct observation were low, although not distinct from the world scenario, reaffirming the need to implement continuous strategies to improve these (AU)

ABSTRACT

OBJECTIVE: Identify rates of adhesion and related factors to acceptance of an alcohol based preparation to hands antiseptic friction among nursing professionals in a unit of intensive therapy. METHOD: A cross-sectional study, which involved direct observation of hand hygiene opportunities and nursing professionals' completion of questionnaires, was conducted at a university hospital between January and July 2015. Descriptive and univariate analyses were performed, with a 5% significance level. RESULTS: It was observed 956 opportunities of hand hygiene among 46 nursing professionals. The rate of adhesion to alcohol-based handrub (ABH) was 34.8% and about 87.0% preferred handwashing. Nurses used ABH more frequently than nursing technicians (p <0.001), and the report of feeling of clean hands after using the alcohol product was directly related to higher rates of adherence to antiseptic friction through observation (P <0.05). CONCLUSION: The finding indicating low ABH usage highlights the need for greater institutional investment in strategies that help health professionals to recognize the advantages of this type of HH with respect to time spent, ease of access to dispensers, effectiveness in eliminating microorganisms, and maintaining skin moisturization.

ABSTRACT

Gaucher disease (GD) is caused by mutations in the glucosylceramidase ß (GBA 1) gene that confer a deficient level of activity of glucocerebrosidase (GCase). This deficiency leads to the accumulation of the glycolipid glucocerebroside in the lysosomes of cells, mainly in the monocyte/macrophage lineage. Its mildest form is Type I GD, characterized by non-neuronopathic involvement. Bone compromise is the most disabling aspect of the Gaucher disease. However, the pathophysiological aspects of skeletal alterations are not yet fully understood. The bone tissue homeostasis is maintained by a balance between resorption of old bone by osteoclasts and new bone formation by osteoblasts. A central player in this balance is the osteocyte as it controls both processes. We studied the involvement of osteocytes in an in vitro chemical model of Gaucher disease. The osteocyte cell line MLO-Y4 was exposed to conduritol-ß-epoxide (CBE), an inhibitor of GCase, for a period of 7, 14 and 21 days. Conditioned media from CBE-treated osteocytes was found to induce osteoclast differentiation. GCase inhibition caused alterations in Cx43 expression and distribution pattern and an increase in osteocyte apoptosis. Osteoclast differentiation involved osteocyte apoptotic bodies, receptor activator of nuclear factor κ-B ligand (RANKL) and soluble factors. Thus, our results indicate that osteocytes may have a role to play in the bone pathophysiology of GD.

ABSTRACT

La proporción de personas mayores de 60 años está aumentando más rápidamente que cualquier otro grupo de edad en casi todos los países como consecuencia del aumento de la esperanza de vida y a la disminución de la tasa de fecundidad. El objetivo de la presente investigación fue conocer la situación socio familiar de las personas adultas mayores que concurren a la consulta de Clínica Médica del Hospital Centenario de la ciudad de Gualeguaychú y la relación con su estado nutricional. El trabajo es correlacional, de corte transversal y se abordó con un enfoque cuantitativo. La técnica utilizada para la recolección de la información fue una encuesta que se realizó a los adultos mayores a través de un encuentro personal. En el cuerpo de la encuesta se incluye la escala de valoración de los recursos socio familiares de Gijón y la escala nutricional Mini Nutritional Assesment. Las pruebas estadísticas mostraron que el mayor número de casos estudiados se encontraba en buen estado nutricional y social. Los datos han sido relacionados y se aplicaron dos pruebas estadísticas de tipo correlacional: una la de Pearson y la otra la de Spearman.Estas pruebas confirmaron que hay una relación significativa entre ambas variables. Se pudo observar cómo la situación nutricional se compromete al aumentar el riesgo social. En relación a esta situación,es necesario un abordaje interdisciplinario en materia de alimentación y nutrición como factor protector y promotor de la salud en este grupo etario.
