RESUMEN Objetivo Determinar las complicaciones crónicas microvasculares en usuarios con diabetes mellitus tipo 2 de una ciudad andina del Perú. Métodos Estudio descriptivo, transversal. Se evaluaron las complicaciones crónicas microvasculares en 22 usuarios con diabetes mellitus tipo 2: la neuropatía, mediante la escala Michigan Diabetic Neuropathy Score; la retinopatía, a través de la biomicroscopía dilatada y cámara retinal, según las pautas de las guías clínicas del Consejo Internacional de Oftalmología, y la nefropatía, según la tasa de filtración glomerular basada en la guía técnica del Ministerio de Salud. Se obtuvieron frecuencias absolutas y relativas y el chi cuadrado de bondad de ajuste con el 95% de confianza y un p-valor significativo <0,05. Resultados La frecuencia de neuropatía fue de 36,4%; el 75% de adultos mayores y el 57,2% de pacientes con 10 o más años con diabetes presentaron neuropatía leve o moderada. La frecuencia de retinopatía fue de 27,3%; el 57,2% de pacientes con 10 o más años con diabetes presentaron algún grado de retinopatía. La frecuencia de nefropatía fue de 4,5%; el 59,1% estuvieron en riesgo de nefropatía y el 50,0% de adultos mayores presentaron posible nefropatía diabética. Conclusión Las complicaciones crónicas más frecuentes en los usuarios evaluados fueron la neuropatía y retinopatía en algún grado de desarrollo. La diferencia con los valores contrastados de otros contextos fue estadísticamente significativa. La actuación oportuna y eficiente ralentizaría la aparición de estas complicaciones, dotando a los afectados de una calidad de vida más placentera.

ABSTRACT Objective To determine the chronic microvascular complications in users with type 2 diabetes mellitus in an Andean city in Peru. Methods Descriptive, cross-sectional study. Chronic microvascular complications were evaluated in 22 users with type 2 diabetes mellitus: neuropathy was tested using the Michigan Diabetic Neuropathy Score; retinopathy, using dilated biomicroscopy and retinal camera, according to the guidelines of the International Council of Ophthalmology clinical guidelines, and nephropathy, according to the glomerular filtration rate based on the technical guide of the Ministry of Health. Absolute and relative frequencies and chi-square goodness of fit were obtained with 95% confidence and a significant p-value <0.05. Results The frequency of neuropathy was 36.4%, of which 75% of older adults and 57.2% of patients with diabetes for 10 years or more had mild or moderate neuropathy. The frequency of retinopathy was 27.3%, of which 57.2% of patients with diabetes for 10 years or more had some degree of retinopathy. The frequency of nephropathy was 4.5%, of which 59.1% were at risk of nephropathy, and 50.0% of older adults had possible diabetic nephropathy. Conclusion The most frequent chronic complications in the evaluated users were neuropathy and retinopathy in some degree of development. The difference with the contrasting values of other contexts was statistically significant. Timely and efficient action would slow down the appearance of these complications, giving those affected a more pleasant quality of life.

Stability of Class II Malocclusion Treatment with the Austro Repositioner Followed by Fixed Appliances in Brachyfacial Patients.

One of the goals of functional-appliance devices is to modify the vertical growth pattern, solving several kinds of malocclusion. This study aimed to evaluate Class II malocclusion treatment's stability with Austro Repositioner, followed by fixed appliances, and assess its capacity to modify vertical dimensions in brachyfacial patients. A test group of 30 patients (16 boys and 14 girls, mean 11.9 years old) with Class II malocclusion due to mandibular retrognathism and brachyfacial pattern treated with Austro Repositioner and fixed appliance were compared to a matched untreated Class II control group of 30 patients (17 boys and 13 girls, mean age 11.7 years old). Lateral cephalograms were taken at T1 (initial records), T2 (end of treatment), and T3 (one year after treatment). Statistical comparisons were performed with a paired-sample t-test and two-sample t-tests. Significant improvements in the skeletal Class II relationship were observed in the treated group. The ANB angle decreased (4.75°), the SNB angle increased (3.92°), and the total mandibular length (Co-Pg) increased (8.18 mm) (p < 0.001). Vertical dimensions were also significantly modified, the FMA angle increased (3.94°), LAFH-distance increased (3.15 mm), and overbite decreased (3.35 mm). These changes remained stable one year after treatment. The Austro Repositioner was adequate for treating the skeletal Class II malocclusion resulting from the mandible retrusion in brachyfacial patients.

Maxillary Sinus Dimensions With Respect to the Posterior Superior Alveolar Artery Decrease With Tooth Loss.

BACKGROUND: The posterior superior alveolar (PSA) artery is frequently encountered in the area where the lateral osteotomy is performed during direct sinus augmentation procedures. OBJECTIVE: To investigate the correlation between patient-dependent variables and measurements related to PSA using cone beam computed tomography (CBCT) data. METHODS: Three hundred ninety-four CBCT scans were evaluated to assess the PSA artery diameter and distances to the sinus floor and to alveolar crest. Patient's age, gender, and edentulism status were recorded. RESULTS: The PSA artery tends to be wider in older patients. Distances to the sinus floor or the alveolar crest tend to be shorter in women and in partially and completely edentulous patients. Also, as those distances decrease, the mediolateral width of the sinus increases. CONCLUSION: Tooth loss leads to maxillary sinus vertical collapse with respect to the PSA artery. The position of the artery is stable; so, the mediolateral dimensions at different heights from the floor increase. PRACTICAL IMPLICATIONS: The reduced distances from the PSA to the sinus floor and the alveolar crest in edentulous patients potentially increase the risk of injury during maxillary sinus lift. Additionally, when the distance to the sinus floor decreases, the mediolateral dimensions of the sinus at different heights increase, which may complicate the technique and challenge the outcomes.

Predictors of Enrollment in Cardiac Rehabilitation Programs in Spain.

PURPOSE: Cardiac rehabilitation (CR) is very effective for secondary prevention of cardiovascular disorders. The objective of this study was to analyze population factors associated with nonenrollment of cardiac patients in these programs. METHODS: Retrospective study of 756 patients referred to the cardiac rehabilitation program (CRP) of a tertiary referral hospital with a service area population of more than 640 000 from January 2009 to June 2012. We assessed the relationship between population characteristics of these patients and nonenrollment by logistic regression analysis. RESULTS: There were 2386 hospital admissions for an acute coronary syndrome during the study period. Out of the 2355 patients who were alive at discharge, 756 (632 men and 124 women) were referred for CR (32.1% vs 3% state average and vs 51% European average). Of these patients, 20.9% did not enroll. The referral rate was lower among women than among men (P < .001). The characteristics associated with a lower rate of enrollment in the program were age (OR: 1.05; 95% CI: 1.02-1.09), living alone (OR: 4.54; 95% CI: 2.53-8.16), living further than 50 km from the CR unit (OR: 2.90; 95% CI: 1.29-6.41) and, in women, having a history of cardiovascular disease (recurrent myocardial infarction) (OR: 6.35; 95% CI: 2.53-11.81). CONCLUSIONS: The rate of referral for CR in our setting is well above the national average but still could be improved. We identified older age, living alone, travel distance to the cardiac rehabilitation unit, and, in women, a history of a previous myocardial infarction as barriers to enrollment in CRPs.
