Variables associated with frailty in a hospital population in Colombia / Variables asociadas a fragilidad en una población hospitalaria en Colombia

INTRODUCTION: Frailty predicts functional decline and could be associated with adverse outcomes such as disability, multiple hospitalizations, falls, loss of mobility, and cardiovascular disease. In Colombia 12.5% of prevalence has been reported. In the present study, the different clinical variables associated with frailty were evaluated in a population of hospitalized patients older than 65 years in Bucaramanga, Colombia, in order to predict the behavior of these variables to generate measurement tools of greater applicability than that of currently existing tools. METHODS: An analytical observational cross-sectional study with non-probabilistic sampling was conducted from January 2016 to June 2017 in patients older than 65 years of follow-up >48 hours by the internal medicine service. Fried criteria were used to evaluate patients on their last day of hospitalization. RESULTS: A total of 155 patients were included, of whom 60.6% were frail. A combined analysis of the variables that showed association with frailty revealed that a calf circumference lower than or equal to 31 cm, a gait speed lower than or equal to 0.8 m/s, and age above 75 years were associated with frailty. It was also shown that being male and having a BMI >27 kg/m2 are protective factors for frailty. CONCLUSIONS: The prevalence of frailty in hospitalized older adults was higher than that reported in local studies for the community population. According to multivariate analysis, the variables, when analyzed together, have a predictive ability of 92% to estimate frailty in hospitalized patients.

INTRODUCCIÓN: El síndrome de fragilidad puede asociarse a mayor riesgo de deterioro funcional y desenlaces adversos como discapacidad, múltiples hospitalizaciones, caídas, pérdida de movilidad y enfermedad cardiovascular. En Colombia se ha reportado una prevalencia del 12,5%. En el presente estudio, se evalúan las diferentes variables clínicas asociadas a fragilidad en una población de pacientes mayores de 65 años en una población hospitalaria en Colombia con el fin de predecir el comportamiento de estas variables y poder general herramientas de detección de mayor aplicabilidad que las que existen actualmente. MÉTODOS: Se realizó un estudio observacional analítico de tipo corte transversal con muestreo no probabilístico desde enero de 2016 a junio de 2017 en pacientes mayores de 65 años en seguimiento > 48 horas por el servicio de medicina interna. Se evaluó la presencia de fragilidad a través de los criterios de Linda Fried, medidos previo al egreso. RESULTADOS: Se incluyeron 155 pacientes, el 60,6% cumplió criterios de Fragilidad. Al realizar el análisis combinado de las variables que mostraron asociación con fragilidad se encontró que una circunferencia de la pantorrilla menor o igual a 31 cm, una velocidad de marcha menor o igual de 0,8 m/seg y ser mayor de 75 años tenían asociación de riesgo para tener fragilidad. También se evidenciaron que ser hombre y tener IMC > 27 kg/m2 , son factores protectores para tener fragilidad. CONCLUSIONES: La prevalencia de fragilidad en adultos mayores hospitalizados fue mayor de la reportada en estudios locales para población comunitaria. De acuerdo con el análisis multivariado, los criterios modificados de Fried incluyendo perímetro de pantorrilla, sin tener en cuenta dinamometría, tienen una capacidad predictiva del 92% para estimar fragilidad en pacientes hospitalizados.

Effect of ketotifen fumarate on experimental autoimmune orchitis and torsion of the spermatic cord / 亚洲男科学杂志(英文版)

The aim of this work was to study effects of ketotifen fumarate (KF) on prevention of tissue damage in testes of rats with experimental autoimmune orchitis (EAO) and on the contralateral testis in a model of prolonged testicular cord torsion (TCT). Rats with EAO or TCT were injected intraperitoneally once daily with KF or saline solution (vehicle group). Incidence and severity of testicular damage were evaluated by histopathology using an EAO score or a Johnsen score. Mast cells (MC) were identified by histochemistry and quantified. In EAO model, KF significantly reduced severity of histopathological testicular damage compared to rats in the vehicle group. KF also reduced the number of testicular MC compared to vehicle group. Similarly, in TCT model, multifocal damage of the contralateral testis was observed 30 days after testicular torsion characterized by sloughing of the germinal epithelium, seminiferous tubule atrophy, and interstitial edema. Focal signs of inflammation and fibrosis of seminiferous tubular walls were also observed. In contrast, sections of contralateral testis of rats injected with KF and killed 30 days after surgery showed normal histological features. A significant decrease in the number of MC was observed in rats treated with KF compared to untreated animals. In conclusion, we demonstrated that treatment with KF reduced testicular inflammatory process and MC infiltrates in both EAO and TCT models. The results suggest a promising treatment for infertile male patients with testicular pathologies associated with inflammation and germ cell loss.

Screening of the UV absorption capacity, proximal and chemical characterization of extracts, and polysaccharide fractions of the Gracilariopsis tenuifrons cultivated in Colombia

The sustainable use of marine resources is a competitive advantage of the most developed countries, which has a positiveimpact on the economic and social development of their populations. Currently, marine organisms such as macroalgaeare an important source of functional compounds such as polysaccharides, proteins, unsaturated and polyunsaturatedfatty acids, among others, with nutritional value and pharmacological properties. Gracilariopsis tenuifrons is amacroalga found in the Colombian Caribbean Sea, which has been neither chemically nor physicochemically studied;therefore, the aim of this study was to evaluate the polysaccharides composition and nutrients contents of crudeextract and its UV radiation absorption capacity. The purification was carried out by ultrafiltration using membranesof molecular size exclusion 100, 50, 10, and 3 kDa. The chemical characterization was done by gel electrophoresis,Nuclear Magnetic Resonance, Fourier Transform Infrared Spectroscopy, and the particle size and potential zeta byDynamic Light Scattering. The absorption coefficient (absorbance/g dry sample) was measured at 290, 310, 340, and380 nm. Sulfated and non-sulfated polysaccharides were detected in the fractions and identified as polysaccharidestype k, and β-carrageenan and alginate. The proximate analysis showed that the total content of protein, carbohydrates,fat, and calories is 15.58%, 69.81%, 0.15%, and 342.94% Kcal, respectively. The crude extracts showed an importantabsorption coefficient in UVB-UVA range. The findings suggest that G. tenuifrons seaweed propagated in vitro is aviable candidate of natural additives, such as phycocolloids and bioactive compounds, for designing new functionalproducts in the pharmaceutical and cosmetic industry, in addition to its nutritional properties to be used in foods.

Difusión analgésica de lidocaína administrada a través de un catéter perilesional en hembras caninas sometidas a mastectomía: un reporte de caso / Analgesic diffusion of lidocaine administered through a wound soaker catheter in female canines undergoing mastectomy: a case report / Difusão analgésica de lidocaína administrada por um catéter perilesional em cadelas submetidas à mastectomía: um relato de caso

Resumen La mastectomía regional en caninos se considera un procedimiento quirúrgico con un grado de dolor intenso, por lo que exige una terapéutica analgésica posquirúrgica efectiva que actúe a favor del bienestar de los pacientes. El manejo farmacológico analgésico sistémico convencional en pacientes de carácter oncológico es deficiente y está fundamentado principalmente en antinflamatorios no esteroidales (AINEs) u opioides de baja potencia. El objetivo del presente reporte es describir el manejo analgésico posmastectomía en dos hembras caninas, mediante el uso de lidocaína como opción fármaco-terapéutica administrada a través de un catéter de difusión analgésica perilesional (MILA ®). Ambos pacientes fueron sometidos a mastectomía regional. Luego de retirar la masa mamaria para cada caso, se instauró un catéter perilesional y se administró lidocaína a 2 mg/kg/ hora de forma intralesional, mediante difusión constante por medio de un catéter y una jeringa perfusora. Se realizaron mediciones de variables fisiológicas y de dolor mediante la escala de la Universidad de Melbourne (UMPS) en ambos pacientes cada 2 horas (T0-T12) durante 24 horas. Ambos pacientes mostraron un descenso en el score de la UMPS durante el periodo de observación posquirúrgica y no hubo cambios significativos en las mediciones de las variables fisiológicas. La infusión intralesional de lidocaína aplicada en los dos pacientes sometidos a mastectomía del presente reporte logró un estado de analgesia posquirúrgico efectivo.

Abstract The regional mastectomy in canines is considered as an intense-pain degree surgical procedure in bitches, which requires an effective post-sur-gical analgesic therapy for the well-being of patients. The conventional systemic analgesic pharmacological management in oncological patients is deficient and is mainly based on non-steroidal anti-inflammatory drugs (NSAIDs) and/or low potency opioids. The present report aimed to describe post-mastectomy analgesic management in two bitches, using lidocaine as a drug-therapeutic option administered through a perilesional anal- gesic diffusion catheter (MILA®). Both patients were subjected to regional mastectomy. After removing the breast mass for each case, a perilesional catheter was placed and the lidocaine was administered at 2 mg/kg/hour intralesionally, by constant diffusion through a catheter and a perfusion syringe. Measurements of physiological and pain variables were collected using the University of Melbourne Scale (UMPS) in both patients every 2 hours (T0-T12) for 24 hours. Both patients showed a decrease in UMPS score during the post-surgical observation period and there were no sig- nificant changes in the measurements of the physiological variables. The intralesional infusion of lidocaine applied in the two patients subjected to mastectomy on this report achieved an effective post-surgical analgesia state.

Resumo A mastectomía regional em caninos é considerada um procedimento cirúrgico comgrau de dor intenso, que requer uma terapia analgésica pós-cirúrgica efetiva que atue em o bem-estar dos pacientes. A terapia farmacológica sistémica analgésico convencional nestes pacientes de características oncológicas é mau e baseada principalmente na antinflamatorios não esteroide (AINE) e/ou de opioides baixa potência. O objetivo deste trabalho é descrever a terapia analgésica pós-mastectomía dois cães fêmeas, através da utilização de lidocaína como opção terapêutico medicamentoso administrado o fármaco através de um cateter de difusão perilesional analgésico (MILA®). Duas cadelas foram submetidas a mastectomía regional. Após a remoção da massa mamária para cada caso, um cateter perilesional foi colocado e lidocaína foi administrada a 2 mg/kg/hora por via intralesional, por difusão constante através de cateter e seringa de perfusão. Medidas de variáveis fisiológicas e de dor foram feitas usando a escala da Universidade de Melbourne (UMPS) em ambos os pacientes a cada 2 horas (T0-T12) por 24 horas. Ambos pacientes mostraram uma diminuição no escore de dor de UMPS durante o período de observação pós-cirúrgica e não houve mudanças significativas nas medidas das variáveis fisiológicas. A infusão intralesional de lidocaína aplicada nas duas cadelas submetidos à mastectomía deste relato alcançou um estado analgésico pós-operatório eficaz.

Confiabilidade da radiografia vestíbulo-lingual na avaliação da obturação endodôntica / Reliability of bucal radiographs to evaluation the root canal fillings

Foi avaliada a confiabilidade da radiografia vestíbulo-lingual em relação à determinação da qualidade e do limite apical de obturações endodônticas utilizando-se canais radiculares de dentes extraídos e a comparação com radiografia realizada no sentido mésio-distal. A análise de qualidade da obturação não demonstrou diferença significante entre radiculares e molares quanto à concordãncia das radiografias VL e MD. Quanto ao limite apical de obturação, as mensurações das radiografias em unirradiculares foram significativamente mais fidedignas do que em molares. Os resultados revelaram que a radiografia periapical não é confiável para a avaliação da qualidade da obturação endodôntica, embora seja relativamente eficaz quanto á avaliação do limite apical da obturação, principalmente em unirradiculares. Estratégias clínicas devem ser estabelecidas para minimizar limitações da análise radiográfica.
