RESUMO

Abstract Background: Since the beginning of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pandemic, patients with chronic kidney disease vulnerable to suffering more severe COVID-19 disease and worse outcomes have been identified Objectives: Our study's aim was to determine the incidence, characteristics, and outcomes of SARS-CoV-2 infection in patients of hemodialysis (HD) units in Mexico and to describe the availability of confirmatory testing Methods: This study was multicentric study of 19 HD units, conducted between March 2020 and March 2021 Results: From a total of 5779 patients, 955 (16.5%) cases of suspicious COVID-19 were detected; a SARS-CoV-2 reverse transcription polymerase chain reaction test was done in only 50.6% of patients. Forty-five percentages were hospitalized and 6% required invasive mechanical ventilation (IMV). There was no significant difference in mortality between confirmed (131/483) and suspicious (124/472) cases (p = 0.74). The percentage of patients in need of hospitalization, IMV, and deceased was greater than in the rest of the study population Conclusions: The study revealed that 49.4% of the cases were not confirmed, a worrisome observation given that this is a highly vulnerable population (higher probability of contagion and worse outcomes), in which 100% of patients should have a confirmatory test

RESUMO

Abstract Background: A high incidence of acute kidney injury (AKI) has been reported in coronavirus disease 2019 (COVID-19) patients in critical care units and those undergoing invasive mechanical ventilation (IMV). The introduction of dexamethasone (DXM) as treatment for severe COVID-19 has improved mortality, but its effects in other organs remain under study. Objective: The objective of this study was to evaluate the association between DXM and AKI in COVID-19. Methods: In this prospective observational cohort study, we evaluated the incidence of AKI in critically ill COVID-19 patients undergoing mechanical ventilation, and the association of DXM treatment with the incidence, severity, and outcomes of AKI. The association between DXM treatment and AKI was evaluated by multivariable logistic regression. The association of the combination of DXM treatment and AKI on mortality was evaluated by Cox-regression analysis. Results: We included 552 patients. AKI was diagnosed in 311 (56%), of which 196 (63%) corresponded to severe (stage 2 or 3) AKI, and 46 (14.8%) received kidney replacement therapy. Two hundred and sixty-seven (48%) patients were treated with DXM. This treatment was associated to lower incidence of AKI (Odds Radio 0.34, 95% Confidence intervals [CI] 0.22-0.52, p < 0.001) after adjusting for age, body mass index, laboratory parameters, SOFA score, and vasopressor use. DXM treatment significantly reduced mortality in patients with severe AKI (HR 0.63, 95%CI 0.41-0.96, p = 0.032). Conclusions: The incidence of AKI is high in COVID-19 patients under IMV. DXM treatment is associated with a lower incidence of AKI and a lower mortality in the group with severe AKI.

RESUMO

Purpose: Bone repair aims to restore the anatomical, biomechanical, and functional integrity of the affected structure. Here we study the effects of ascorbic acid (AA) and epidermal growth factor (EGF) applied in a single dose and in combination on the repair of a noncritical bone defect model. Methods: Twenty-four rats were divided into four groups: an intact G-1 control group, and three groups that underwent a noncritical bone defect in the right tibia: G-2 treated with AA, G-3 treated with EGF, and G-4 treated with AA in combination with EGF. After 21 days of treatment, rats were sacrificed, the tibias were dissected and a destructive biomechanical analysis of three-point flexion test was performed in a universal testing machine; the values of stiffness, resistance, maximum energy, and energy at maximum load were statistically compared. Results: G-3 and G-4 recovered the biomechanical properties of strength and stiffness of an intact tibia 3 weeks after their application. Not so the energy and energy at maximum load. For G-2, only the stiffness of an intact tibia was recovered. Conclusion: EGF and AA-EGF applied to a noncritical bone defect in the rat tibia favors the recovery of bone resistance and stiffness.

RESUMO

The lysosome is responsible for protein and organelle degradation and homeostasis and the cathepsins play a key role in maintaining protein quality control. Cathepsin D (CTSD), is one such lysosomal protease, which when deficient in humans lead to neurolipofuscinosis (NCL) and is important in removing toxic protein aggregates. Prior studies demonstrated that CTSD germ-line knockout-CtsdKO (CDKO) resulted in accumulation of protein aggregates, decreased proteasomal activities, and postnatal lethality on Day 26 ± 1. Overexpression of wildtype CTSD, but not cathepsin B, L or mutant CTSD, decreased α-synuclein toxicity in worms and mammalian cells. In this study we generated a mouse line expressing human CTSD with a floxed STOP cassette between the ubiquitous CAG promoter and the cDNA. After crossing with Nestin-cre, the STOP cassette is deleted in NESTIN + cells to allow CTSD overexpression-CTSDtg (CDtg). The CDtg mice exhibited normal behavior and similar sensitivity to sub-chronic 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP) induced neurodegeneration. By breeding CDtg mice with CDKO mice, we found that over-expression of CTSD extended the lifespan of the CDKO mice, partially rescued proteasomal deficits and the accumulation of Aβ42 in the CDKO. This new transgenic mouse provides supports for the key role of CTSD in protecting against proteotoxicity and offers a new model to study the role of CTSD enhancement in vivo.

RESUMO

Abstract Objective: To determine the effects of physioprophylaxis (PP) on blood lactate (BL) concentrations after maximal incremental stress test, considering that this is the application of techniques in sports physiotherapy to reduce signs of muscle fatigue that can trigger injuries due to overload. Materials and Methods: Quantitative study, experimental type, longitudinal section in 12 university players. The group is divided into one control group (CG) with recovery at rest without PP and another experimental group (EG) to which PP is applied at the end of the test. Blood lactate is recorded with Accutrend Plus at the beginning of the test, (1) five minutes after finishing the test (2) and after the PP (3) at two different moments for intra-subject analysis. Results: The following data were obtained regarding blood lactate clearance, Moment 1: Without Plan (WoP) 4.86±1.4 and With Plan (WP) 8.85±1.25 (p<0.05), moment 2: (WoP) 5.6±1.76 and (WP) 7.8±1.3 (p<0.05) in mmol/L, and intra-subject: (WoP): 5.25±1.58; (WP): 8.35±1.33 (p<0.05). Conclusions: The clearance of lactate in the blood at 30 minutes post stress test in the EG is bigger than the CG, because they recovered with the physioprophylactic plan.


Resumen Objetivo: Determinar los efectos de la fisioprofilaxis (PP) sobre las concentraciones de lactato en sangre (BL) tras la prueba de esfuerzo incremental máximo, considerando que se trata de la aplicación de técnicas en fisioterapia deportiva para reducir los signos de fatiga muscular que pueden desencadenar lesiones por sobrecarga. Materiales y métodos: Estudio cuantitativo, tipo experimental, sección longitudinal en 12 jugadores universitarios. El grupo se divide en un grupo control (GC) con recuperación en reposo sin PP y otro grupo experimental (GE) al que se aplica PP al final de la prueba. El lactato sanguíneo se registra con Accutrend Plus al inicio de la prueba, (1) cinco minutos después de finalizar la prueba (2) y después de la PP (3) en dos momentos diferentes para el análisis intra-sujeto. Resultados: Se obtuvieron los siguientes datos con respecto al aclaramiento de lactato en sangre, Momento 1: Sin Plan (WoP) 4.86 ± 1.4 y Con Plan (WP) 8.85 ± 1.25 (p <0.05), Momento 2: (WoP) 5.6 ± 1.76 y (WP) ) 7,8 ± 1,3 (p <0,05) en mmol / L, e intra-sujeto: (WoP): 5,25 ± 1,58; (WP): 8,35 ± 1,33 (p <0,05). Conclusiones: El aclaramiento de lactato en sangre a los 30 minutos post prueba de esfuerzo en el GE es mayor que en el GC, debido a que se recuperaron con el plan fisioprofiláctico.

RESUMO

Introduction: We previously found that the occurrence of congenital Zika syndrome was under-reported in Mexico. It was postulated that high dengue virus antibody levels found at the population-level in endemic countries might have contributed to the occurrence of the regional pandemic of Zika disease. A case series of suspected cases of congenital Zika syndrome in a maternity hospital in Tuxtla Gutierrez, Chiapas, Mexico was assembled to assess why they were not reported and to explore the hypothesis of dengue virus antibody-dependent enhancement of Zika disease. Methods: We used a quantitative approach to describe clinical and imaging records and used data from interviews of a total of 13 suspected cases of congenital Zika syndrome. We also quantitated dengue 1 and 2 antibodies using an 80% plaque reduction neutralization test of sera specimens obtained from the mothers of these 13 cases and compared them to those of a group of mothers who delivered normal newborns in the same hospital. Results: Only one of the suspected cases was laboratory-confirmed because appropriate specimens were not collected from the newborns as required by the case definition. We found 1) microcephaly, 2) hypoplasia/hypogeneses, thinning or absence of brain structures, 3) multiple birth defects, 4) calcifications, and cysts, 5) meningocele/encephalocele, and 6) hydrocephalus in 100 %, 76.9 %, 38.5 %, 38.5 %, 30.8 %, and 23.1 %, respectively of the case series. The cases clustered geographically, and 77 % occurred between May 2016 to March 2017 and recalled or were told by a doctor they had Zika fever. There was a four-fold increased risk of congenital Zika syndrome among those with dengue 1 antibody as compared to those with dengue 2 antibodies (odds ratio = 3.6; 95 % confidence interval: 0.7, 20.5), reaching only borderline statistical significance. Conclusions: We found in the largest maternal facility of the capital of the State of Chiapas, in Mexico, that only 7.7 % of suspected cases were confirmed, and that the rather complex requirement of cerebrospinal fluid specimens or serological specimens of newborns for suspected cases of congenital Zika syndrome used during the pandemic resulted in low sensitivity of the surveillance system. The finding of higher levels of dengue 1 than dengue 2 antibodies in cases than the referent population, requires further evaluation and may suggest a role for dengue antibody-dependent response in Zika disease.


Introducción: Previamente los autores habían encontrado evidencia de sub-notificación de la ocurrencia del síndrome congénito por Zika en México. Se ha postulado que niveles elevados de anticuerpos contra los virus del dengue a nivel poblacional en los países endémicos hubiese contribuido a la ocurrencia de la pandemia regional de enfermedad por Zika. Ensamblamos una serie de casos sospechosos de síndrome congénito por Zika en un hospital de maternidad en Tuxtla Gutiérrez, Chiapas, México, para evaluar por qué no fueron notificados y explorar la hipótesis de enfermedad por Zika incrementada por anticuerpos anti-dengue. Métodos: Utilizamos un enfoque cuantitativo para describir 13 casos sospechosos de síndrome congénito por revisamos registros clínicos e imágenes, entrevistas. También cuantificamos los niveles de anticuerpos para los virus dengue 1 y 2 en suero de las madres de los casos comparados con los de mujeres que tuvieron recién nacidos normales en el mismo hospital. Resultados: Solamente uno de los 12 casos sospechosos fue confirmado por laboratorio, porque en los demás no se recolectaron especímenes adecuados de los neonatos como lo requería la definición de casos. Encontramos 1) microcefalia, 2) hipoplasia y adelgazamiento de las estructuras cerebrales, 3) malformaciones múltiples, 4) calcificaciones o quistes, 5) meningocele/encefalocele, y 6) hidrocefalia en: 100 %, 76.9 %, 38.5 %, 38.5 %, 30.8 %, y 23.1 %, en ese orden entre los casos sospechosos. Los casos se aglutinaron geográficamente y 77 % ocurrieron entre Mayo del 2016 y Marzo del 2017, y sus madres recordaban que tuvieron o que un profesional de la salud les dijo que tuvieron fiebre por Zika. Encontramos un incremento de casi 4 veces en el riesgo de síndrome congénito por Zika para aquellos con altos niveles de anticuerpos anti-dengue 1 comparado con anticuerpos anti-dengue 2 (cociente de suertes = 3.6; intervalo de confianza del 95 %: 0.7, 20.5), alcanzando solamente una significancia estadística limítrofe. Conclusiones: Encontramos en el establecimiento de atención a la maternidad más grande en la capital de Chiapas, México, que solamente 7.7 % de los casos sospechosos de síndrome congénito por Zika fueron confirmados y que los relativamente complejos requerimientos de la definición de casos de muestras serológicas o de líquido cefalorraquídeo resultó en una baja sensibilidad del sistema de vigilancia. El hallazgo de niveles más altos de anticuerpos a dengue 1 que dengue 2 requiere más evaluación y pudiera sugerir un papel de la respuesta dependiente de anticuerpos al dengue en Zika.

RESUMO

Objetivo: Evaluar el síndrome de burnout (SB) en cirujanos generales. Material y Método: Se realizó un estudio de corte transversal en nuestro centro hospitalario, en agosto de 2021. La muestra estuvo formada por 56 profesionales de la salud que incluyeron a residentes y especialistas en cirugia general quienes prestaron servicio en el contexto de la COVID-19. Resultados: La prevalencia del burnout fue del 71%, la edad media fue de 34 años y los residentes fueron los más afectados (62,5%). La distribución por sexo fue de 82,5% en masculinos y 17,5% en el sexo femenino. Del total de evaluados, 23 son casados y 17 solteros, predominando los cirujanos con hijos (60%). Discusión: Entre los pocos estudios publicados sobre el SB en trabajadores de la salud en tiempos de COVID-19 se ubican como posibles factores predisponentes: a las privaciones de sueño, el riesgo biológico ocupacional intrínseco, la cuarentena obligada a la que tienen que someterse los trabajadores de la salud fuera de casa y los dilemas éticos en la toma de decisiones de atención a pacientes. Sin embargo, un estudio ha mostrado que los estresores vinculados al SB más importantes son la falta de equipo de protección personal, el miedo al contagio de COVID-19 y el miedo de contagiar a los familiares. Conclusión: Existe una alta prevalencia del SB en cirujanos generales en el contexto de la pandemia COVID-19. Los más afectados fueron residentes jóvenes de sexo masculino, casados, con hijos y con bajos ingresos económicos.


Objective: To evaluate the burnout syndrome (BS) in general surgeons. Material and Method: A cross-sectional study was carried out in our hospital in August 2021. The sample consisted of 56 health professionals that included residents and specialists in general surgery who provided service in the context of COVID-19 Results: The prevalence of burnout was 71%, the mean age was 34 years and the residents were the most affected (62.5%). Sex was 82.5% in males and 17.5% in females. Of the total evaluated, 23 are married and 17 are single, with a predominance of surgeons with children (60%). Discussion: Among the few studies published on BS in health workers in times of COVID-19, the following are located as possible predisposing factors: sleep deprivation, intrinsic occupational biological risk, the forced quarantine that patients have to undergo. out-of-home health workers and ethical dilemmas in patient care decision-making. However, a study has shown that the most important stressors linked to BS are the lack of personal protective equipment, the fear of contagion of COVID-19 and the fear of infecting family members. Conclusion: There is a high prevalence of BS in general surgeons in the context of the COVID-19 pandemic. The most affected were young male residents, married, with children and with low income.

RESUMO

Resumen: Introducción: Las complicaciones postquirúrgicas han sido causa importante de muerte. Por lo tanto, el uso de predictores sencillos de mortalidad con una nueva escala llamada SASA podría indicar un riesgo postoperatorio de mortalidad a los 30 días aplicado en una muestra en población mexicana. Material y métodos: Exploramos una asociación entre la clasificación de estado físico de la Sociedad Americana de Anestesiólogos (ASA-PS), el Apgar quirúrgico (sAs) y la puntuación de SASA con un análisis univariado en 371 pacientes estimando la relación de probabilidades (OR) y graficando las curvas de operación característica del receptor (receiver-operating-characteristic [ROC]) para cada escala. Resultados: Obtuvimos los valores de dos; [sensibilidad; 81.82% (IC del 95%: 48.2-97.72), especificidad; 40.56% (IC del 95%: 35.44-45.83)], 6; [sensibilidad; 81.82% (IC del 95 %: 48.2-97.72), especificidad; 77.5% (IC del 95%: 72.83-81.71)] y 10; [sensibilidad; 81.82% (IC del 95%: 48.2-97.72), especificidad; 83.6% (IC del 95%: 78.77-86.78)] como los mejores puntos de corte para el ASA-PS, sAs y SASA respectivamente. Conclusiones: el cálculo de SASA obtuvo la misma sensibilidad, pero mejor especificidad y área bajo la curva cuando se comparó con el ASA-PS y el sAs.


Abstract: Introduction: Post-surgical complications have been a significant cause of death. Therefore, the use of easy preoperative mortality predictors is recommended. A new SASA score could indicate a perioperative risk more globally at 30-days of the postoperative period applied in a Mexican sample. Material and methods: 371 patients were analyzed. We explore an association between the American Society of Anesthesiologists physical status classification (ASA-PS), the surgical Apgar score (sAs), and the new SASA score to assess 30-days mortality after surgery using univariate analysis to estimate the odds ratio (OR). Receiver-operating-characteristic (ROC) curves were plotted for each scale. Results: We obtained values of two; [sensitivity; 81.82% (95% CI: 48.2-97.72), specificity; 40.56% (95% CI: 35.44-45.83)] 6; [sensitivity; 81.82% (95% CI: 48.2-97.72), specificity; 77.5% (95% CI: 72.83-81.71)] and 10; [sensitivity; 81.82% (95% CI: 48.2-97.72), specificity; 83.6% (95% CI: 78.77-86.78)] as the best cut-off points for ASA-PS, sAs and SASA respectively. Conclusions: To predict postoperative 30-days mortality, SASA calculation as a new score obtained the same sensitivity but better specificity and area under the curve (AUC) for the ROC compared with the ASA-PS and the sAs.

RESUMO

Objetivo Evaluar el conocimiento en el uso de Medicamentos de Uso Veterinario (MUV) de los productores ganaderos y personal involucrado en Bogotá y municipios aledaños. Métodos Se realizó un estudio de corte transversal a través de entrevistas a operarios y productores ganaderos de una muestra de 30 hatos lecheros localizados en 15 municipios cerca de Bogotá, Cundinamarca. Resultados Se identificó la implementación de prácticas para la administración de MUV, incluyendo parámetros que influencian su administración y conocimientos en las personas que los prescriben y administran. Se encontró que los medicamentos de mayor frecuencia fueron los antimicrobianos con 60,7%, entre los cuales se destaca el uso de penicilina y oxitetraciclina. Los MUV inyectables (parenterales) fueron las formas más frecuentes de aplicación con un 64,7%. Se identificaron 251 MUV en los hatos lecheros, de los cuales el 81,3% están compuestos por principios activos que requieren tiempo de retiro en leche y carne. Se destaca el rol del mayordomo en el cuidado animal a nivel diagnóstico y administración del tratamiento. Conclusión El presente estudio sugiere que el uso de MUV es implementado empíricamente en producciones lecheras y podría contribuir a mediano y largo plazo a la emergencia de cepas con resistencia a MUV.


Objective To evaluate the knowledge in the antibiotic stewardship practices in livestock producers and associated staff from Bogotá and neighboring municipalities. Methods A cross-sectional study was performed through interviews for livestock producers and staff in a sample of 30 dairy farms located in 15 municipalities near Bogota, Cundinamarca. We evaluated practice administration of veterinary drugs and knowledge in antibiotic stewardship by farm livestock managers in charge who prescribe and administer veterinary drugs. Results The most common veterinary drugs were antimicrobials with 60.7% such as penicillin and oxytetracycline. The injectable veterinary drugs (parenteral) were the most frequently used with 64.7%. We identified 251 veterinary drugs in the dairy farms where 81.3% of active compounds require withdrawal time in the milk and meat. The butler role in animal care was highlighted at diagnostic level and treatment compliance. Conclusion This study suggests that recommendations for veterinary drug stewardship remain empirically implemented in dairy farms which might lead to the future emergence of multidrug-resistant strains in the long and middle term.

RESUMO

Resumen Introducción: La cardiopatía isquémica es un problema de salud pública y puede tratarse por medio de la revascularización miocárdica. Objetivo: Estructurar el primer perfil epidemiológico y clínico de los pacientes intervenidos en Tolima. Materiales y método: Es un estudio de corte transversal, de 183 pacientes mayores de 18 años programados para revascularización miocárdica entre septiembre de 2018 y septiembre de 2019. Se eligieron variables clínicas y demográficas. Se realizó un análisis descriptivo, un análisis bivariado para mortalidad y circulación extracorpórea, y una regresión logística para la mortalidad intrahospitalaria. Resultados: La edad media de los pacientes fue de 66.7 años y un 68.85% correspondió a la población femenina. Se presentó HA en 80.33%, tabaquismo en 49.18%, dislipidemia en 44.81% y DM en 40.98%. Se registró mayor proporción de complicaciones en los pacientes intervenidos sin CEC, como complicaciones pulmonares, FA de novo y una estancia intrahospitalaria y posoperatoria mayor. Los pacientes que fallecieron tuvieron mayor proporción de complicaciones, mayor estancia hospitalaria, mayor cantidad de reintervenciones y tiempo de ventilación mecánica. El modelo de regresión reveló una relación con mortalidad para los pacientes que tuvieron requerimiento de diálisis (OR = 8.7) complicaciones pulmonares (OR = 10.5) y desarrollo de FA de novo (OR = 11.3). Conclusiones: Este estudio caracteriza a la población para generar marcos de referencia en un grupo poco estudiado como el tolimense. De modo adicional, se presentaron mejores desenlaces en los pacientes llevados a revascularización miocárdica con circulación extracorpórea, y unas relaciones claras de mortalidad y complicaciones posoperatorias.


Abstract Introduction: The ischemic cardiopathy is a public health issue, that can be treated with a coronary artery bypass grafting (CABG). Objective: To present the first clinical and epidemiological profile of CABG treated patients in Tolima, Colombia. Materials and method: We conduct a cross sectional study, including 183 patients driven to a CABG procedure, between September 2018-2019. We chose clinical and demographic variables. And posteriorly, performed a descriptive and bivariate analysis, including mortality and extracorporeal circulation. Besides, we completed a logistic regression for intrahospital mortality. Results: The average age of our patients was 66,7 years, and 68.85% were female. They presented in an 80.33% arterial hypertension, smoked an 49.18%, had dyslipidemia and diabetes 44.81% and 40.95% respectively. There were more complications in patients who were drove into on pump CABG, primarily pulmonary complications, atrial fibrillation, mayor intrahospital and post-operatory stay. The patients who died, present more complications, intrahospital stay, reinterventions and mechanic ventilation time. Our regression model evidenced mortality association with post-operatory dialysis (OR = 8.7), pulmonary complications (OR = 10.5) and new atrial fibrillation (OR = 11.3). Conclusions: This study aim to characterize the Tolima's population, creating a reference in this less studied population. On the other side, the study discuss the better outcomes in patients taken to myocardial bypass with extracorporeal membrane oxygenation. And the association between dead and certain postoperative complications.

RESUMO

Abstract The aim of this study was the quantification of Sphingosine-1-phosphate (S1P) in periodontal pockets of patients with periodontitis. This is an observational, descriptive, case-control study. Thirty subjects were selected: 15 controls and 15 cases. A periodontal study was conducted following the parameters of AAP 2017 for the diagnosis of periodontal diseases. A sample of saliva and gingival crevicular fluid was obtained from each subject and then analyzed with the Human S1P Elisa kit (MyBioSource #MBS2516132) accordingly to the manufacturer's instructions, in order to verify the presence of S1P and quantify it´s concentration when founded. Results showed a significant difference (p=0.05) between cases and controls. In the case of saliva samples, the concentration of S1P was higher than the ones found in the control group (72.94 ng/mL and 45.12 ng/mL). For GCF, a higher amount of S1P was found in patients with POD (20.09 ng/mL and 15.20 ng/mL). This work raises a possible route of bone metabolism, inflammatory process, and identification of periodontitis through oral quantification of S1P, however, future studies are needed.


Resumen El propósito de este estudio fue la cuantificación de Esfingosina-1-Fosfato (S1P) en las bolsas periodontales de pacientes con periodontitis. Estudio observacional, descriptivo de casos y controles. 30 sujetos fueron seleccionados de los cuales 15 controles y 15 casos. Se realizó un estudio periodontal completo siguiendo los parámetros establecidos por la AAP en 2017 para el diagnóstico de las enfermedades periodontales. Se tomaron muestras de saliva y de líquido crevicular gingival de cada sujeto estudiado y se analizaron con el ELISA kit humano para S1P (MyBiosource #MBS2516132) y de acuerdo con las instrucciones del fabricante, se realizó para cuantificar la presencia d S1P en las muestras estudiadas. Los resultados mostraron diferencia significativa (p=0.05) entre casos y controles. En el caso de las muestras de saliva, la concentración de S1P en controles fue mayor (72.94 ng/mL y 45.12 ng/mL). Para Líquido crevicular gingival, se encontró mayor cantidad de S1P en los pacientes con periodontitis (20.09 ng/mL y 15.20 ng/mL). Este estudio plantea una posible ruta de metabolismo óseo, proceso inflamatorio e identificación de la Periodontitis a través de la cuantificación oral de S1P, sin embargo se necesitan estudios futuros.

RESUMO

Objetivo: Analizar la tendencia del indicador "Infección del tracto urinario asociado a instalación de catéter urinario a permanencia" en Chile. Material y Método: Estudio ecológico, de series temporales en el sistema sanitario de Chile, correspondiente a un total de 15 regiones, desde el año 2001 al año 2017 (27.087.087 casos). Se incluyeron datos cuyo egreso hospitalario era infección de tracto urinario asociado a catéter urinario a permanencia, según la Clasificación Internacional de Enfermedades (CIE 10). El análisis descriptivo y correlacional (X2 y T de Student, respectivamente) se realizó en función del sexo, tipo de previsión, condición de egreso y operación quirúrgica. El análisis se realizó con el programa SPSS 24 y el nivel de significación estadística fue p< 0,05. La estimación, basada en análisis lineal, estimó cambios porcentuales anuales (APC: Annual Percentage Change) y sus intervalos de confianza al 95%. Se empleó el método de auto-regresión de Prais Winsten. El resguardo ético siguió lo dispuesto en la Ley N° 20.585. Resultados: Se observó un 2% de crecimiento interanual (APC= 0,00007; IC: 95%= 0,000069-0,000073). En los años 2005, 2008, 2009 y 2011 existió un aumento en el porcentaje de cambio de 2 a 5 puntos. Conclusión: El indicador analizado es un evento que ha presentado una tendencia creciente y significativa en Chile desde el año 2001, lo que resulta paradójico, puesto que el ordenamiento de los procesos hospitalarios, asociado a la Reforma de Salud, debería demostrar una mejora en el comportamiento de este tipo de indicadores.


Objective: To analyze the trend indicator "Urinary tract infection associated with indwelling urinary catheter insertion" in Chile. Material and Method: Ecological, time series study, carried out in the Chilean health system, corresponding to a total of 15 administrative regions, from 2001 to 2017 (27.087.087 cases). Data included information on patients whose hospital discharge was urinary tract infection associated with indwelling urinary catheter, according to the International Classification of Diseases (ICD-10). Descriptive and correlational analysis (X2 and Student's t-test, respectively) was performed according to sex, type of health insurance, hospital discharge condition and surgical operation. The analysis was performed using SPSS 24 software and the level of statistical significance was p<0.05. The estimation was based on linear analysis, estimating annual percentage changes (APC) and their 95% confidence intervals. The Prais-Winsten autoregression method was used. Ethical considerations followed the provision of Law No. 20.585. Results: A 2% interannual growth rate was observed (APC= 0.00007; CI: 95% = 0.000069-0.000073). In the years 2005, 2008, 2009 and 2011 there was an increase in the percentage change of 2 to 5 points. Conclusion: The analyzed indicator corresponds to an event that has shown a significant and increasing trend in Chile since 2001, which seems paradoxical, since hospital processes management, associated with the health care reform, should show an improvement regarding this type of trend indicator.

RESUMO

Las malas condiciones nutricionales en muchas localidades mayas de Yucatán, México, persisten, a pesar de que se han implementado diversos programas. El objetivo fue comparar los efectos de una intervención nutricional basada en la comunidad con enfoque intercultural (INBC) y una intervención nutricional convencional (INC), sobre el índice de masa corporal (IMC) y la dieta en mujeres de localidades mayas de Yucatán. Fueron incluidas mujeres adultas con IMC ≥ 25kg/m2 de dos pequeñas localidades rurales mayas vecinas. Ambas intervenciones fueron de tres meses y con 11 sesiones, siguiendo la normatividad vigente; en la INBC fue utilizada la herramienta intercultural, denominada Plato del Bien Comer Maya, además se incluyeron en la INBC estrategias diseñadas con base en información obtenida en una fase previa de estudio cualitativo con entrevistas. El grupo con la INBC (n = 7), en comparación con el grupo con la INC (n = 9), tuvo una mayor disminución de IMC (-0,58 ± 0,70 kg/m2 y +0,27 ± 0,64 kg/m2; p = 0,042), de la circunferencia de cintura (-2,15 ± 2,60 cm y -0,50 ± 0,75 cm; p = 0,042) y del consumo de grasas (-53,23 ± 21,92 gramos y -7,34 ± 25,77 gramos; p = 0,004), así como mayor incremento en las frecuencias semanales de consumo de algunos alimentos locales como nance (p = 0,012), tamarindo (p = 0,001) y chile (p = 0,004), la INBC fue la única que presentó una disminución significativa en el consumo diario de calorías (basal: 2.067 ± 91 kcal/día, a los tres meses: 1.474 ± 31 kcal/día; p = 0,018), hubo en ambos grupos disminuciones en el consumo de alimentos ultraprocesados, pero sin diferencias comparando los grupos; el grupo con la INBC obtuvo mejores resultados que el grupo con la INC.


Poor nutritional conditions persist in many Mayan communities in Yucatán, Mexico, even though various programs have been implemented. The study aimed to compare the effects of a community-based nutritional intervention with an intercultural focus versus a conventional nutritional intervention on body mass index (BMI) and diet in women in Mayan communities in Yucatán. The sample included adult women with BMI ≥ 25kg/m2 from neighboring rural Mayan villages. Both interventions lasted three months with 11 sessions and followed the prevailing guidelines. The community-based intervention used an intercultural tool called Good Mayan Food [Plato del Bien Comer Maya], besides strategies designed according to information obtained from a prior qualitative study phase using interviews. The group that received the community-based intervention (n = 7), compared to the conventional intervention group (n = 9), showed larger decreases in BMI (-0.58 ± 0.70 kg/m2 and +0.27 ± 0.64kg/m2; p = 0.042), waist circumference (-2.15 ± 2.60 cm and -0.50 ± 0.75 cm; p = 0.042), and consumption of fats (-53.23 ± 21.92 grams and -7.34 ± 25.77 grams; p = 0.004), as well as higher increases in weekly consumption of some local foods such as nance fruit (p = 0.012), tamarind (p = 0.001), and chili peppers (p = 0.004). The community-based intervention was the only one to show a significant decrease in daily calorie intake (baseline: 2,067 ± 91 kcal/day, at three months: 1,474 ± 31 kcal/day; p = 0.018), and both groups showed decreases in the consumption of ultra-processed foods, but without significant differences between the two groups. The community-based intervention group showed better results than the conventional intervention group.

O objetivo era comparar os impactos de uma intervenção nutricional baseada na comunidade com enfoque intercultural (INBC) e uma intervenção nutricional convencional (INC), sobre o índice de massa corporal (IMC) e a dieta de mulheres de localidades maias de Yucatán. Foram incluídas mulheres adultas com IMC ≥ 25kg/m2 de duas pequenas localidades rurais maias vizinhas. Ambas as intervenções duraram três meses e contaram com 11 sessões, conforme as normas vigentes; na INBC, foi utilizada a ferramenta intercultural denominada Prato de Comer Bem Maia [Plato del Bien Comer Maya], além de estratégias adicionais idealizadas com base em dados obtidos em uma fase prévia de estudo qualitativo com entrevistas. Em comparação com o grupo com a INC (n = 9), o grupo com a INBC (n = 7) teve maior diminuição de IMC (-0,58 ± 0,70 kg/m2 e +0,27 ± 0,64 kg/m2; p = 0,042), da circunferência abdominal (-2,15 ± 2,60 cm y -0,50 ± 0,75 cm; p = 0,042) e do consumo de gorduras (-53,23 ± 21,92 gramas y -7,34 ± 25,77 gramas; p = 0,004), bem como um aumento maior das frequências semanais de consumo de alguns alimentos locais como o murici (p = 0,012), o tamarindo (p = 0,001) e pimenta (p = 0,004). A INBC foi a única a apresentar uma diminuição significativa do consumo diário de calorias (inicial: 2.067 ± 91 kcal/dia, após três meses: 1.474 ± 31 kcal/dia; p = 0.018). Houve em ambos os grupos redução equivalente do consumo de alimentos ultraprocessados; o grupo com a INBC obteve melhores resultados que o grupo com a INC.

RESUMO

Resumen Introducción: Los gramnegativos continúan siendo los causantes de infecciones asociadas a la atención a la salud (IAAS). Material y métodos:: Analizamos la resistencia antimicrobiana de patógenos durante el 2013 vs. 2018 y lo comparamos con lo publicado en 2006 vs. 2012. Resultados: Identificamos nueve patógenos gramnegativos, de un total de 404 aislamientos, con una prevalencia en 2013 (N = 227 [0.22]) vs. 2018 (N = 177 [0.17]) y una incidencia por egresos (6,607 en el 2013 y 7,778 en el 2018) del 3.4 y 2.2% respectivamente. Destacaron tres patógenos: Klebsiella pneumoniae (129 [31.93%]), Pseudomonas aeruginosa (85 [21.03%]) y Escherichia coli (80 [19.80%]). Estos, llamados patógenos ESKAPE-E, prevalecieron como causantes de IAAS. Identificamos un aumento en los patrones de resistencia para muchos patógenos en 2018. Conclusión: La multirresistencia a patógenos ESKAPE-E es un serio problema de salud pública, por carecer de alternativas terapéuticas para enfrentar este reto. Los mapas de resistencia bacteriana ayudan en la prescripción antibiótica.


Abstract Background: Gram-negatives continue to be the cause of infections associated with health care (HCAI). Material and methods: We analyzed the antimicrobial resistance of pathogens during 2013 vs. 2018 and we compare it with what was published in 2006 vs. 2012. Results: We identified 9 gram-negative pathogens, out of a total of 404 isolates, with a prevalence in 2013 (N = 227 [0.22]) vs. 2018 (N = 177 [0.17]) and an incidence due to discharges (6,607 in 2013 and 7,778 in 2018) of 3.4 and 2.2%, respectively.Three pathogens stood out Klebsiella pneumoniae (129 [31.93%]), Pseudomonas aeruginosa (85 [21.03%]) and Escherichia coli (80 [19.80%]). These, called ESKAPE-E pathogens, prevailed as the cause of HCAI. We identified an increase in resistance patterns for many pathogens in 2018. Conclusion: Multi-resistance to ESKAPE-E pathogens is a serious public health problem, due to the lack of therapeutic alternatives to face this challenge. Bacterial resistance maps help in antibiotic prescription.

RESUMO

Resumen La temática en salud de la mujer toca demasiados aspectos, desde el nacimiento hasta la senectud. Hay ciertas afecciones que están relacionadas con el sexo biológico, pero también con problemas de sexualidad, desigualdad social y muchos tipos de violencia. Por ello se requiere analizar y adaptar la información en materia de salud, para implementar acciones hacia la población objetivo. Si bien en primera instancia la atención médica involucra la salud física, se han vuelto equiparables la salud mental y la social. Con el enfoque en este grupo de riesgo, se integran lineamientos prácticos, normas e información científica actualizada, para explicar las principales medidas que debe tomar cualquier mujer en todo el curso de su vida, y con ello mantener un estado de salud satisfactorio, buscar atención oportuna en ginecología y obstetricia, ademís de poder definir el plan de seguimiento médico personalizado. Se presentan herramientas prácticas mediante la exposición de un decálogo, denominados mandamientos, que sirven tanto para el médico como para la paciente, a fin de favorecer el bienestar físico, mental y social; sin perder la connotación de los distintos grupos etarios, así como lo alusivo a la función reproductiva y el ciclo gestacional.


Abstract The subject of women's health touches too many aspects, from birth to old age. There are certain conditions that are related to biological sex, but also to problems of sexuality, social inequality, and many types of violence. Therefore, it is necessary to analyze and adapt the information on health, to implement actions towards the target population. Although at first instance medical care involves physical health, mental and social health have become comparable. Focusing on this risk group, practical guidelines, standards and updated scientific information are integrated to explain the main measures that any woman should take throughout her life, and thereby maintain a satisfactory state of health, seek care in Gynecology and Obstetrics, in addition to being able to define the personalized medical follow-up plan. Practical tools are presented through the exposition of a decalogue, called commandments, which serve both the doctor and the patient, in order to promote physical, mental and social well-being; without losing the connotation of the different age groups, as well as the allusion to the reproductive function and the gestational cycle.

RESUMO

RESUMEN El neotrópico es sitio de origen de gran variedad de plantas que actualmente son cultivadas con éxito en diferentes regiones del mundo. Sin embargo, condiciones climáticas adversas, que se pueden ver acrecentadas por efectos del cambio climático antropogénico, pueden afectar su rendimiento y productividad debido a las situaciones de estrés abiótico que se pueden generar. Como alternativa para contrarrestar estos efectos, se ha experimentado con modificaciones genéticas, particularmente en genes relacionados con la producción de osmolitos y factores de transcripción que han llevado a que estas plantas, a nivel experimental, tengan mayor tolerancia a estrés oxidativo, altas y bajas temperaturas y fotoinhibición, sequía y salinidad, mediante la acumulación de osmoprotectores, la regulación en la expresión de genes y cambios en el fenotipo. En este trabajo se presentan y describen las estrategias metodológicas planteadas con estos fines y se complementan con ejemplos de trabajos realizados en cultivos de origen neotropical de importancia económica, como maíz, algodón, papa y tomate. Además, y debido a la novedad y potencial que ofrece la edición génica por medio del sistema CRISPR/Cas9, también se mencionan trabajos realizados en plantas con origen neotropical, enfocados en comprender e implementar mecanismos de tolerancia a sequía. Las metodologías aquí descritas podrían constituirse en opciones prácticas para mejorar la seguridad alimentaria con miras a contrarrestar las consecuencias negativas del cambio climático antropogénico.


ABSTRACT The neotropics are the site of origin of a large variety of plants that are currently successfully cultivated in different regions of the world. However, adverse climatic conditions, which can be exacerbated by the effects of anthropogenic climate change, can affect their yield and productivity due to the abiotic stresses that can be generated. As an alternative to counteract these effects, genetic modifications have been experimentally implemented, particularly in genes related to osmolyte production and transcription factors, which have ultimately led to increased tolerance of these plants to oxidative stress, high and low temperatures and photoinhibition, drought and salinity, through the accumulation of osmoprotectants, regulation of gene expression and changes in phenotype. In this work, the methodological strategies proposed to these aims are presented and described, and they are complemented with examples of studies carried out in economically important crops of neotropical origin, such as corn, cotton, potato and tomato. In addition, and due to the novelty and potential that gene editing offers through the CRISPR/Cas9 system, works conducted in plants with neotropical origin, focused on understanding and implementing drought tolerance mechanisms, are also mentioned. The methodologies described here could become practical options to achieve food security in the frame of the adverse effects caused by anthropogenic climate change.

RESUMO

ABSTRACT Objetive To determine the validity and reliability of the CUCACE (Quality of Nursing Care Questionnaire) in Colombia. Every day there is a growing interest in measuring the quality of care received from nursing personnel as a tangible element of care; however, not having reliable and valid instruments is an obstacle, especially in Colombia. Method A psychometric and evaluative instrumental study was conducted. Data of interest from CUCACE filled out in Spanish were extracted together with demographic information of the participants. Results Confirmed the validity of the content and construct validity of the scales of care, attention to nursing care and the perception of care in a Colombian hospital. Cronbach's alpha was higher than 0.7, and its reliability is accepted in the context. Conclusion The CUCACE is adequate to measure the satisfaction and experience of patients with nursing care in the Colombian context. The questionnaire with its two scales is useful, clear, precise, valid and reliable to evaluate the quality of nursing care.

RESUMO

RESUMEN La atención al paciente crítico requiere del manejo del sistema cardiovascular y del equilibrio del medio interno, por lo cual es necesario el monitoreo hemodinámico. Con el objetivo de describir el sustento fisiológico del monitoreo hemodinámico y los medios para su determinación se realizó una búsqueda de información en las bases de dato Scopus, SciELO, PubMed, LILACS, AmeliCA y Redib. El monitoreo hemodinámico permite determinar la necesidad de administrar fluidos y su respuesta terapéutica; al analizar la curva de Frank-Starling. Además, necesita la determinación de parámetros estáticos y dinámicos, que analizan el gasto cardíaco, la presión de pulso, medidos mediante métodos invasivos, mínimamente invasivos y no invasivos. La variabilidad de la presión de pulso y del volumen sistólico constituyen nuevas variables útiles en el proceso. El estudio mediante ecocardiografía de la vena cava inferior juega un importante papel en el monitoreo hemodinámico.


ABSTRACT Caring for the critically ill patient requires management of the cardiovascular system and balance of the internal environment. Hemodynamic monitoring is therefore necessary. With the objective of describing the physiological basis of hemodynamic follow-up and means for its determination, a search for information was carried out in the -Scopus, SciELO, PubMed, LILACS, AmeliCA, and Redib- databases. Hemodynamic monitoring allows determining when fluid administration is required and its therapeutic response by analyzing the Frank Starling curve. It requires the determination of static and dynamic parameters that analyze cardiac output and pulse pressure. These parameters are measured by invasive, minimally invasive and noninvasive methods. Pulse pressure and stroke volume variability are useful new variables in the process. Echocardiographic study of the inferior vena cava plays an important role in the hemodynamic follow-up.
