RESUMO

BACKGROUND: The 8th edition of the American Joint Committee on Cancer (AJCC) classification has introduced two new parameters: depth of invasion (DOI) and extranodal extension (ENE). The aim of this systematic review was to determine whether this 8th edition referred to oral squamous cell carcinoma (OSCC) offers performance superior to that of the 7th edition in relation to overall survival (OS) and disease-specific survival (DSS). MATERIAL AND METHODS: The review was carried out following the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-analyses) guidelines. The PubMed (MEDLINE), Scopus and Cochrane Library databases were searched covering the period up until April 7th, 2022. RESULTS: Thirteen retrospective cohort studies were finally included. The introduction of DOI and ENE in the 8th edition of the AJCC classification resulted in improved prognostic performance of the classification. CONCLUSIONS: Patients with OSCC can be better classified in relation to OS and DSS, while maintaining the simplicity and ease of use of the classification. This allows more appropriate treatment protocols to be applied and affords a better estimation of the prognosis of each patient.

RESUMO

INTRODUCTION: Few studies exist that research the association between umbilical cord characteristics with cardiac malformations. In this study, we describe a population of newborns with congenital heart defects (CHD) and the frequency of presentation of umbilical cord (UC) alterations, based upon the hypothesis that the continuity of the cardio-placental circuit can be affected by similar noxas during early development. METHODS: We carried out a descriptive study at a hospital in Bogota based on clinical records from newborns with congenital heart disease with placental and UC pathology results. Group analyses were done according to the major categories of the ICD-10. RESULTS: We analyzed 122 cases and found that the most frequent alterations where hypercoiling (27.9%) and abnormal UC insertion (16.4%). Additionally, in almost every group of CHD, more than 65%of patients had some type of cord alteration. CONCLUSION: We discovered a high frequency of UC alterations in patients with CHD. This outcome suggests that a possible association exists between the two phenomena, further research is needed.

RESUMO

Wheat flour is a known sensitizer for humans. Bakers exposed to flour dust may develop occupational rhinitis and asthma. In Chile there is no current permissible limit for occupational exposure to wheat flour. To propose such a limit, 9 bakeries located in 6 districts of Santiago de Chile were evaluated, 6 bakeries were semi-industrial and 3 were small business. Twenty-eight environmental personal samples were obtained by standard sampling methods and they were analyzed at the Institute of Public Health of Chile. No significant differences were found (p = 0,2915, Kruskall-Wallis' test) between air concentrations of flour particles in the working environment of semi-industrial (geometric mean: MG = 0.88 mg/m³,geometric deviation: DEG = 2,68) and small business (MG = 1.39 mg/m³, DEG = 2,31). A permissible limit of wheat flour dust exposure is recommended.


Se conoce que la harina de trigo es un sensibilizador en seres humanos. Los panaderos expuestos a polvo de harina pueden desarrollar rinitis y asma ocupacional. En Chile actualmente no existe un límite permisible para la exposición ocupacional a polvo de harina. Con el objetivo de proponer un límite, fueron evaluadas 9 panaderías de 6 comunas de Santiago de Chile, de las cuales 6 fueron semi-industriales y 3 pequeñas. Un total de veintiocho muestras personales de aire fueron obtenidas según método estándar de muestreo y analizadas en el Instituto de Salud Pública de Chile. No se encontraron diferencias significativas (p = 0,2915, prueba de Kruskall-Wallis) en la concentración de partículas de harina en el ambiente de trabajo semi-industrial (media geométrica: MG = 0,88 mg/m³, desviación geométrica: DEG = 2,68) y en el de panaderías pequeñas (MG = 1,39 mg/m³, DEG = 2,31). En base a las observaciones realizadas se recomienda establecer un límite permisible de exposición para polvo de harina de trigo.

RESUMO

OBJECTIVE: To evaluate the quality of life in patients with knee and hip osteoarthritis through self-assessment and those made by the physician. MATERIALS AND METHODS: An observational and cross-sectional multicenter study in which 628 traumatologists or rheumatologists evaluated 1,849 patients with knee and/or hip osteoarthritis, aged ≥ 50 years old, and representative of 49 Spanish provinces. Each researcher evaluated three patients and also completed the SF-12v2 health questionnaire. The patients completed the WOMAC and SF-12v2 questionnaires. RESULTS: The patients were 68.5 ± 9.5 years old, 61.5% had knee osteoarthritis, 19% had hip osteoarthritis, and 19.5% in both locations. Older patients and those who had both knee and hip osteoarthritis had a poorer quality of life, according to patients and researchers. Physical health perceived by the researchers was better than patients reported (36.74 ± 8.6 and 35.21 ± 8.53; respectively, p<0.001), and the mental health score was similar between physicians and patients. Kellgren/Lawrence scale and test Timed Up & Go predict better the quality of life, assessed by WOMAC and SF-12v2 questionnaires. DISCUSSION: This is the Spanish study on quality of life in osteoarthritis of the knee and hip of larger amplitude and number of patients. CONCLUSION: These results could be considered as reference values of Spanish population aged ≥ 50 years with knee or hip osteoarthritis.

RESUMO

The paper presents a technique that allows the simultaneous monitoring of the dielectric properties of liquids in microfluidic channels at microwave frequencies. It is capable of being integrated within the lab-on-a-chip concept and uses a composite right/left-handed transmission line resonator which is detuned by the dielectric loading of the liquids in the channels. By monitoring the change in the resonance spectrum of the resonator the loading profile can be derived with the multi-resonant perturbation method. From the value of the dielectric constant inference on the substances like cells or chemicals in the channels can be drawn. The paper presents concept, design, fabrication and characterization of prototype sensors. The sensors have been designed to operate between 20 and 30 GHz and were tested with water and water ethanol mixtures.

RESUMO

La alta incidencia de las fracturas por fragilidad y especialmente de las fracturas vertebrales (FV) en mujeres con osteoporosis posmenopáusica obliga a abordar este tema una y otra vez. En este manuscrito se actualizan los datos epidemiológicos que indican la magnitud del problema y se revisan alternativas de tratamiento farmacológico, tanto para disminuir el dolor producido por la FV como para prevenir la presentación de nuevas fracturas osteoporóticas de cualquier tipo, indicando los agentes antirresortivos y osteoformadores disponibles actualmente. En los casos de FV por compresión, en las que el tratamiento farmacológico habitual no produce mejoría del dolor y siempre que no existan contraindicaciones, puede ser muy apropiado realizar vertebroplastia o cifoplastia (AU)


The high incidence of fractures by fragility and, especially of the vertebral fractures in osteoporotic postmenopausal women, forces us to approach this subject once more. In this manuscript epidemiological data that indicates the magnitude of the problem will be updated. Treatment alternatives to decrease back pain produced by vertebral fracture are will be reviewed, and the prevention of the occurrence of new osteoporotic fractures of any type, through the administration of suitable antiresorptive and bone-forming pharmacological agents to increase bone mineral density will also be addressed. In some patients with painful vertebral compression fractures it is possible obtain an analgesic effect by percutaneous vertebroplasty or by kiphoplasty using polymethylmetacrilate cement or calcium- phosphate cement, injected into vertebral bodies (AU)

RESUMO

El presente estudio bibliográfico tiene como propósito conocer el Síndrome de Burnout, su desarrollo, factores de riesgo, factores protectores y consecuencias de éste en los profesionales de enfermería que trabajan en Unidades de Cuidados Intensivos (UCI), e identificar las principales estrategias de prevención e intervención, citadas por la bibliografía, que inciden en la disminución de la prevalencia de dicho síndrome, en el personal de enfermería. Se revisan las diferentes definiciones del concepto de Síndrome de Burnout, desde la realizada por Freudenberger en el año 1974 hasta la fecha, y se describe el proceso de desarrollo del síndrome. Se identifican los diferentes factores, tanto personales como ambientales, que desencadenan el síndrome en los profesionales de enfermería de UCI y de servicios generales, los factores protectores y las consecuencias del Burnout en el profesional, paciente, institución, familia y sociedad en general. Además, se describe el MBI (Maslash Burnout Inventory), instrumento de mayor utilización a nivel mundial en la evaluación del síndrome y además el Burnout Measure (BM). Finalmente se identifican las principales estrategias de prevención y se proponen algunas intervenciones a nivel nacional para disminuir la prevalencia del Síndrome de Burnout en los profesionales de enfermería. Los resultados de la presente revisión sobre el Síndrome de Burnout en enfermería de UCI, indican que los factores ambientales no se correlacionan significativamente con el desarrollo del síndrome; sin embargo, los factores individuales inciden más significativamente en la prevalencia del Burnout. Se destaca que el Síndrome de Burnout puede contagiarse entre colegas. En cuanto a la prevención, por cada dólar invertido en programas de intervención y prevención del Síndrome de Burnout, se obtienen cinco dólares de ganancia.


The purpose of this bibliographical study is to know the Burnout Syndrome, its development, risk factors, protective factors and its consequences on the professional nurses who work at ICU and to identify the main prevention and intervention strategies -quoted in the bibliography- that have an impact in the prevalence decrease of such syndrome in the nursery personnel. The different definitions of the Burnout Syndrome were revised, since the one made by Freudenberger in 1974 until today and the syndrome development process was described. The different factors -both personal and environmental- that cause the syndrome in nursery professionals who work in ICUs and in general services were identified, as well as the protection factors and the consequences of the Burnout Syndrome in professionals, patients, the health institution, the family and the society in general. Furthermore, the MBI (Maslash Burnout Inventory), the most used instrument worldwide to evaluate the syndrome, and the BM (Burnout Measure) is described. Finally, the main prevention strategies are identified and some national interventions are proposed in order to decrease the Burnout Syndrome prevalence in the professionals of the nursery area.The results of this revision about the Burnout Syndrome in Intensive Care Nursery indicate that the environmental factors do not significantly correlate with the development of the syndrome. However, individual factors have a more significant influence in the prevalence of the Burnout Syndrome. The fact that the syndrome may be contagious among colleagues stands out. Concerning prevention, each dollar invested in intervention and prevention programs of the Burnout Syndrome turns out to be a five-dollar profit.

RESUMO

Objetivo. Relacionar la densidad mineral ósea (DMO), las fracturas y algunos probables factores de riesgo de fractura en mujeres postmenopáusicas de la Comunidad de Extremadura. Pacientes y métodos. Se estudiaron 304 mujeres postmenopáusicas (edad:5079 años), 138 sin historia clínica de fractura (grupo sin fractura) y 166 con fracturas después de los 50 años (grupo con fracturas). En el grupo sin fracturas fueron causa de exclusión las enfermedades y tratamientos que pueden afectar el metabolismo óseo, la menopausia precoz, inmovilización de más de 6 meses y la historia de fracturas. Se determinó la DMO en columna lumbar (L2-L4), lateral, cuello de fémur y triángulo de Ward, mediante absorciometría dual de rayos X (método DXA). Se aplicó un cuestionario para obtener la historia de fracturas, edad de la menopausia, antecedentes familiares de osteoporosis y/o de fracturas, consumo de lácteos, tabaco, café y alcohol, exposición al sol, paridad, actividad física y hábitat. Se analizaron los datos utilizando el paquete estadístico SPSS. Resultados. La edad, talla, peso e índice de masa corporal (IMC) fueron similares en ambos grupos, pero se observó diferencia en la edad de la menopausia (p < 0,001). La DMO en el grupo con fracturas fue más baja que en el grupo sin fracturas, en todas las localizaciones evaluadas (p < 0,001). En el grupo con fracturas, el 19,9 por ciento tenía DMO normal, el 45,8 por ciento, osteopenia y el 34,3 por ciento osteoporosis. La edad de la fractura fue 59,8 ñ 6,1 (m ñ DE) años. Se encontraron fracturas de cadera, Colles, miembro inferior, más de una fractura y en diversas localizaciones que correspondían a costillas, pelvis, húmero, clavícula, dedos, omóplato y codo. La más frecuente y la única que presentó DMO similar al grupo sin fracturas fue la fractura de miembro inferior. El odds ratio del antecedente familiar de osteoporosis y/o fracturas para las fracturas de cualquier localización fue 2,404 (IC del 95 por ciento: 1,315-4,396) y OR:4,242 (IC del 95 por ciento: 2,028-8,875) para las fracturas de cadera y Colles, consideradas conjuntamente. Entre las mujeres que se exponían al sol más de 30 minutos/día, además de la insolación (nivel medio-alto), el 80,2 por ciento pertenecían al grupo sin fracturas y el 19,8 por ciento habían tenido fracturas de cadera o de Colles. No se encontró relación entre frecuencia de fracturas y actividad física, paridad, consumo de café y de alcohol. Conclusiones. Las mujeres extremeñas mayores de 50 años, que presentan osteopenia, antecedentes familiares de osteoporosis y/o de fracturas, menopausia temprana y escasa exposición al sol tienen riesgo de sufrir fracturas de cadera, Colles o más de una fractura en diversas localizaciones del esqueleto, exceptuando las de miembro inferior (AU)

RESUMO

The idea of an interuniversity project between the Universidad Central de Las Villas, Cuba and the University of Ghent, Belgium was conceived in order to improve the quality of the Cuban agriculture and to stimulate its independence from foreign chemical farm inputs, starting with an applied ethnobotanical investigation as basis for the development of sustainable agricultural practices. The project consists of three parts. The first, ethnobotanical part, subtends the two subsequent stages, i.e. the phytochemical and pharmacological stages. After ethnobotanical inventarization of plants with a possible phytotoxic or pesticide effect, these will be collected and taxonomically defined. Fresh vegetal material will be dried and ground, and this first crude extract (polar or apolar) will be tested for its activity in in vitro biological tests. When results are positive (presence of activity), this crude extract will be tested in vivo, which could lead to immediate application in agriculture (short-term strategy). The long-term strategy will lead to the identification of chemical substances, responsible for the activity of the crude extract. As highly sophisticated apparatus is needed for this last step (i.e. identification of chemical compounds), this will be performed by the Department of Organic Chemistry, Faculty of Agricultural and Applied Biological Sciences of the University of Ghent. The project has started in September 2000. Apart from all the (complicated) administrative steps to be undertaken for its successful execution, the ethnobotanical and phytochemical parts have already started. Ethnobotanical data were gathered in view of recollection of "traditional botanical knowledge", considering three main approaches: the use of plants in medicine, in Cuban religion (the famous "santería") and the use of allelopathic plants in agriculture. Use of medicinal and religious plants is ubiquitous in Cuba. The concept of allelopathy, however, is much less known and applied. At this moment, and after preliminary screening and gathering of field data, in vitro germination tests are running, trying out extracts of tobacco (Nicotiana tabacum), banana (Musa spp.), sunflower (Helianthus annuus), Simarouba glauca and S. laevis (syn. Quassia, fam. Simaroubaceae).

RESUMO

Objetivo. Obtener un patrón normal de densitometría ósea en niños y adolescentes sanos y su relación con la edad y los parámetros antropométricos de talla, peso e índice de la masa corporal (IMC). Pacientes y métodos. Se estudiaron 113 niños y adolescentes, 85 hombres y 54 mujeres (edad: 10-18 años), estratificados por sexo y edad. Fueron causa de exclusión las enfermedades y tratamientos que pueden afectar el metabolismo óseo, la práctica de deportes de competición y la inactividad física prolongada. Se determinó la densidad mineral ósea (DMO) en columna lumbar (L2-L4), cuello de fémur, trocánter y triángulo de Ward, mediante absorciometría dual de rayos X. Los valores de DMO se correlacionaron con la edad y con cada uno de los parámetros antropométricos. Resultados. La DMO de columna lumbar aumenta significativamente con la edad en ambos sexos (p < 0,001), desde 0,736 ñ 0,115 a los 10-12 años hasta 1,013 ñ 0,066 g/cm2 a los 16-18 años en mujeres y en los hombres desde 0,664 ñ 0,054 hasta 1,003 ñ 0,096 g/cm2 a las mismas edades. El pico máximo es igual en ambos sexos, alcanzándose antes en las mujeres (14-16 años) que en los hombres (16-18 años). Se observó diferencia significativa de la DMO lumbar según el sexo, en todos los grupos de edad, excepto a los 16-18 años. La DMO de cuello de fémur aumenta en mujeres desde 0,708 ñ 0,106 hasta 0,893 ñ 0,052 g/cm2 a los 10-12 y 16-18 años, respectivamente y en hombres desde 0,736 ñ 0,066 hasta 1,006 ñ 0,117 g/cm2, a las mismas edades. El pico de masa ósea de cuello de fémur es mayor en hombres y se alcanza a los 16-18 años. Se observó diferencia significativa de la DMO de cuello de fémur entre hombres y mujeres sólo a los 16-18 años. Existe correlación ( p < 0,001) entre la DMO lumbar y edad, talla, peso e IMC en ambos sexos. El peso es mejor predictor de DMO lumbar (R2 = 0,53) y de cuello de fémur (R2 = 0,50) que la edad, la talla y el IMC. Conclusiones. 1. Se establecen patrones de normalidad de DMO en una población sana de niños y adolescentes. 2. Existe correlación entre la densidad ósea y la edad, talla, peso e índice de masa corporal. 3. La densidad ósea lumbar es mayor en las mujeres en todas las edades. 4. La densidad ósea de cuello de fémur es mayor en hombres desde los 10 a 18 años (AU)

RESUMO

We analyzed retrospectively the outcome of 169 patients in chronic hemodialysis (CHD), divided into four groups: 1) 24 patients with diabetic nephropathy (age 53.7 +/- 11 years); 2) 19 with polycystic kidney disease (age 55.3 +/- 9 years) 3) 43 patients older than 60 when starting chronic hemodialysis with etiologies different from diabetes and polycystic kidney disease (age 69.2 +/- 5.8 years) and 4) 83 patients younger than 60 with diverse etiologies (age 42.8 +/- 12.4 years). In groups 1, 2 and 3 serum creatinine, arterial hypertension at the beginning, morbility, mortality and its causes were registered. In group 1, the prevalence of severe diabetic retinopathy and cardiovascular disease at the beginning were also analyzed. In all groups survival was determined. Of the diabetics, 92% presented severe diabetic retinopathy and 88% cardiovascular disease. The prevalence of hypertension was 100, 74 and 67% in groups 1, 2 and 3, respectively (p = 0.13). Twelve diabetics died before the first year of treatment; there was no difference in creatinine, age, cardiovascular disease, severe retinopathy and hypertension with those who lived more than one year. The percentage of time in risk hospitalized and the days/patients/year hospitalized were significantly different between group 1 and 3 and group 2 (p < 0.001). Patients were hospitalized for similar causes in groups 1 and 3: the initiation of CHD, cardiovascular and neurological diseases. The main causes of death in groups 1 and 3 were: cardiovascular disease and sudden death at home. Survival was better in group 2 compared with group 1 (p = 0.0014) but was similar between groups 1 and 3 (p = 0.21) even though there was a difference of 15 years between them. The Cox's proportional hazard model identified as risk factors diabetes, age, year of starting chronic hemodialysis and hospitalization episodes, adjusted for covariates. The outcome of diabetic patients in chronic hemodialysis showed high morbidity and mortality and was quite similar to that of elderly patients.

RESUMO

Se presenta experiencia con un programa preventivo de ambliopia y su eficacia indudable. Se examino 1.037 ninos de 4 anos de edad. Se eligio este grupo etario, pues es posible evaluar en ellos la agudeza visual obteniendose mejores resultados con un tratamiento mas breve. El nivel de vision alcanzado fue satisfactorio en un plazo de 12 meses (promedio) en el 84% de los casos, resultado estadisticamente significativo. Se pudo confirmar fechacientemente con el grupo de testigo que el diagnostico tardio hace imposible la recuperacion de la ambliopia en un alto porcentaje de casos. Se propone incluir la toma obligatoria de la agudeza visual de 4 anos de edad por personal previamente adiestrado por un equipo oftalmologico
