Osteotomía valgizante de tibia: estudio de dos técnicas quirúrgicas

Se evalúan clínica y radiológicamente 51 rodillas artrósicas tratadas median - te osteotomía tibial valguizante según dos técnica s diferentes con fines comparativos. En 37 rodillas se empleó la osteotomía en cúpula con fijador externo y en las restante s se practicó la técnica en cuña de sustracción. El período de seguimiento medio fue de 42.2 meses. La suma de resultados buenos y excelente s ha sido 77.9%. La osteotomía en cúpula tiene , en esta serie, un mayor índice de pérdidas de corrección, correcciones insuficientes y complicaciones, obteniendo menor porcentaje de buenos resultados. Estos se deterioran en pacientes de mayor edad y gonartrosis evolucionada. Los autores consideran la osteotomía valguizante de tibia, un tratamiento válido par a pacientes de edad no avanzada y con gonartrosis grados I y II con genu varo.Two tecniques o f high tibia l osteotom y i n fifty-one ostheoarthiti c knee s evaluate d b y roentgenographi c an d clinica l examination .

Indicaciones Límite de las Fracturas de Húmero con Clavo Endomedular Cerrojado

El tratamiento de las fracturas diafisarias del húmero ha entrado en controversia en los últimos años, como lo refleja la literatura internacional. La problemática aumenta cuando se trata de fracturas diafisarias límites que alcanzan la zona metafisaria superior e inferior. En un intento de mejora terapéutica este grupo de autores ha testado un clavo cerrojado para el húmero diseñado por Seidel. El promedio de seguimiento ha sido de 12 meses con un mínimo de 6 meses. El número de casos evaluados ha sido 6. Siguiendo la cotación de Stewart, 4 de los seis pacientes obtuvieron resultados buenos o excelentes. Todos los pacientes consolidaron sus fracturas en un período de tiempo normal, entre 3 y 5 meses, con una media de 4 meses, 4 de los seis pacientes no se inmovilizaron con yeso en ningún momento. La bondad y sencillez del método hace augurar buenos resultados en otros grupos ampliando sus indicaciones.Treatment of dyaphyseal fractures of the humerus has been the source of considerable controversy in recent years. The problem increases in dimension when one is dealing with limiting diaphyseal fractures that invole the upper and lower metaphyseal zone. In an attempt to improve the therapy of this circunstance, the members of this research team have tested a locking nail for the humerus designed by Seidel. The mean follow-up time has been 12 months, with a minimum of six months. The number of cases evaluated was 6. According to the scale of Stewart, four of the cases obtained good or excellent results. All the patients consolidated their fractures within a normal period of time -between 3 and 5 months-, with a mean of 4 months. Four of the 6 patients wer e not immobilized with paster at any time. The goodness and simplicity of the method are suggestive of promising results in other groups by broadening its indications

From Nuevo León to the USA and Back Again: Transnational Students in Mexico

The movement of Mexicans to the United States is both longstanding and long studied and from that study we know that for many newcomers the attachment to the receiving community is fraught and tentative. The experience of immigrant children in U.S. schools is also relatively well studied and reveals challenges of intercultural communication as well as concurrent and contradictory features of welcome and unwelcome. What is less well known, in the study of migration generally and of transnational students in particular, is how students moving in a less common direction — from the U.S. to Mexico — experience that movement. Based on visits to 173 randomly selected classrooms in the state of Nuevo León Mexico, this study shares survey and interview data from 208 of the 242 students encountered who had previous experience attending school in the United States

Dietary animal and plant protein intakes and their associations with obesity and cardio-metabolic indicators in European adolescents: The HELENA cross-sectional study

Background: Previous studies suggest that dietary protein might play a beneficial role in combating obesity and its related chronic diseases. Total, animal and plant protein intakes and their associations with anthropometry and serum biomarkers in European adolescents using one standardised methodology across European countries are not well documented. Objectives: To evaluate total, animal and plant protein intakes in European adolescents stratified by gender and age, and to investigate their associations with cardio-metabolic indicators (anthropometry and biomarkers). Methods: The current analysis included 1804 randomly selected adolescents participating in the HELENA study (conducted in 2006-2007) aged 12.5-17.5 y (47% males) who completed two non-consecutive computerised 24-h dietary recalls. Associations between animal and plant protein intakes, and anthropometry and serum biomarkers were examined with General linear Model multivariate analysis. Results: Average total protein intake exceeded the recommendations of World Health Organization and European Food Safety Authority. Mean total protein intake was 96 g/d (59% derived from animal protein). Total, animal and plant protein intakes (g/d) were significantly lower in females than in males and total and plant protein intakes were lower in younger participants (12.5-14.9 y). Protein intake was significantly lower in underweight subjects and higher in obese ones; the direction of the relationship was reversed after adjustments for body weight (g/(kg.d)). The inverse association of plant protein intakes was stronger with BMI z-score and body fat percentage (BF%) compared to animal protein intakes. Additionally, BMI and BF% were positively associated with energy percentage of animal protein. Conclusions: This sample of European adolescents appeared to have adequate total protein intake. Our findings suggest that plant protein intakes may play a role in preventing obesity among European adolescents. Further longitudinal studies are needed to investigate the potential beneficial effects observed in this study in the prevention of obesity and related chronic diseases

Labile haemoglobin as a glycaemic biomarker for patient-specific monitoring of diabetes: mathematical modelling approach.

Diabetes mellitus constitutes a major health problem and its clinical presentation and progression may vary considerably. A number of standardized diagnostic and monitoring tests are currently used for diabetes. They are based on measuring either plasma glucose, glycated haemoglobin or both. Their main goal is to assess the average blood glucose concentration. There are several sources of interference that can lead to discordances between measured plasma glucose and glycated haemoglobin levels. These include haemoglobinopathies, conditions associated with increased red blood cell turnover or the administration of some therapies, to name a few. Therefore, there is a need to provide new diagnostic tools for diabetes that employ clinically accessible biomarkers which, at the same time, can offer additional information allowing us to detect possible conflicting cases and to yield more reliable evaluations of the average blood glucose level concentration. We put forward a biomathematical model to describe the kinetics of two patient-specific glycaemic biomarkers to track the emergence and evolution of diabetes: glycated haemoglobin and its labile fraction. Our method incorporates erythrocyte age distribution and utilizes a large cohort of clinical data from blood tests to support its usefulness for diabetes monitoring
