Entrance examinations for postgraduate students are used by institutions to value their capacity to perform during their studies and excel in professional practice. The medical field leverages this practice for postgraduate students to select the best candidates to enter a rigorous program where participants are responsible for patients outcomes. Therefore it is important to analyze the quality and predictability of those examinations. The objective of this study was to analyze the predictability of the medical residency entrance examination for academic performance. As part of the analysis, we correlated the academic performance of the 2018 generation of graduates in thirteen medical specialties at Tecnologico de Monterrey, with 64 students' test scores. Academic performance was divided into students who graduated with honors and excellence (scores ≥90) and without honors. The admission test score has an 800-points total and was classified as high (≥600) and standard(≥550). The...

Bread loses crispness rapidly after baking because water originating from the wet crumb accumulates in the dry crust. This water accumulation might be increased by the dense and low permeable character of the bread crust. Our objective was to investigate the influence of permeability of the crust on water uptake in the crust and on crispness retention. To achieve this objective, we increased the permeability of the control bread crust by creating small channels through the crust. The water vapour permeability of the crust with and without channels was measured using a newly developed method for brittle materials. Two further properties were measured over time: crispness of bread by analysing acoustic properties and water content of the crust. Control bread crust had low water vapour permeability and functioned as a barrier, leading to increased uptake of water in the crust. Water uptake was halved, however, if the water vapour permeability of the crust was doubled. As a consequence, crispness retention increased eight-fold; breads stored for four hours were as crispy as control breads stored for 30 min. We can conclude, therefore, that permeability of crust is key to crispness retention.

A 57-year-old Mexican man presented on a follow-up appointment with the neurologist, he complained of dyspnea on exertion in November of 2016, the neurologist referred him with the cardiologist in 2017, the cardiologist ordered a cycle ergometry, an echocardiogram and a CT scan that was abnormal, with these results the cardiologist referred the patient with a pneumologist, who ordered a transoral biopsy, the results of the biopsy were no conclusive so the pneumologist proceed to order a surgical lung biopsy with thoracotomy approach in which they found Pseudomona in bronchoalveolar lavage (BAL) without treatment. The patient has lost weight in 4 months before he goes with the urologist for a follow-up appointment, he presented with cough and sputum production of 6 months of evolution. The patient has medical story of Diabetes Mellitus Type 2 diagnosed since 1997 currently treated with glibenclamide, metformin and insulin, the patient also presents complications of diabetes, like diabetic neuropathy treated with gabapentin, and as a complication of the poor glycemic control he presented with diabetic nephropathy that derive in renal failure and needed for a year hemodialysis until he was transplanted. The medication he uses to be immunocompromised is sirolimus (2mg), mycophenolic acid (500 mg) and prednisone. He also has diagnostic of hypertension treated actually with verapamil, he had a diagnostic of pulmonary tuberculosis in 2007 treated with the antituberculous regimen, that consisted of two phases; an intensive phase followed by a continuation phase, he presented with the physician with productive sputum with blood, cough and loss of weight and in 2012 he presented again with pulmonary tuberculosis He has diagnostic of benign prostatic hyperplasia treated with Finasteride and alfuzosin, he also is taking pentoxifylline for chronic occlusive arterial disease. He is taking actually travoprost, and as a complication of the poor glycemic control he is taking ranibizumab for the diabetic retinopathy. As surgical record, the patient had and appendectomy in 1980, at the age of 17 years old he had a sublingual abscess, that was drained, the surgical removed of a lipoma in 2008 and has record of 2 phacoemulsifications in 2011 and in 2017. He refers no family history of lung disease, he mentions that one sister died of renal and pulmonary complications, another sister had problems with tuberculosis and mentions that his father has diagnostic of POCD. The patient mentions that he doesn´t smoke, but he was exposed for 32 years to the cigar smoke that his father used to smoke in their house, he mentions that he is a teacher and works near 2 fabrics but the fabrics doesn´t work with silica and titanium

cIMPACT-NOW (the Consortium to Inform Molecular and Practical Approaches to CNS Tumor Taxonomy) was established to evaluate and make practical recommendations on recent advances in the field of CNS tumor classification, particularly in light of the rapid progress in molecular insights into these neoplasms. For Round 2 of its deliberations, cIMPACT-NOW Working Committee 3 was reconstituted and Louis et al Meeting report of cIMPACT-Utrecht Brain Pathology 0 (2020) 1-13
