Objective: The objective of this study was to identify the time period during which a hospital bed could be virtually available according to the informatics and administrative hospital system while still being physically occupied by a patient in a hospital in Mexico., Materials and Methods: A cross-sectional study was conducted in a 250-bed Academic Medical Center located in Central Northern Mexico during February 2015. Both administrative and real patient discharges were registered in a hospital format. Central tendency measures were used to present collected data and bed/day costs were obtained from official national published costs., Results: Nine hundred and forty-three patients were followed up during their hospital discharge process. Overall, 2.4% of hospital beds were occupied by discharged patients. The annual cost only for cold beds was $959,220.00 US$ ($14,348,304.00 MNX), without bringing about any benefits for patients. Cold beds represented 1.31% of the 2015 annual hospital budget., Conclusions: Quality improvement initiatives must be implemented to allocate beds to patients more efficiently. The discharge process must be standardized to reduce bed/day direct hospital costs and strengthen the supervision of medical residents during this process., (Copyright: © 2020 Permanyer.)

Background: Up to 30% of the population has sleep disturbances, generating a negative health impact, a situation that is often not known and no medical attention is sought. It has been observed that after a total deprivation of sleep, the levels of dipeptidyl peptidase 4 (DPP-4) tend to increase. The aim of this study was to compare serum levels of DPP-4 in healthy subjects, with adequate and poor-quality sleep needing medical/pharmacological treatment. Materials and Methods: Cross-sectional study of subjects scheduled for elective surgery with low cardiometabolic risk. Subjects between 18-70 years of age were included, without previous diagnosed pathology (diabetes mellitus type 2; neoplasm; nephropathy; and liver disease) and major amputations, and who signed informed consent. The study protocol was aproved in the Local Committee for Ethics and Research, number 45-16. Anthropometry was performed (% body fat; waist and neck circumferences), and sleep quality assessment (Pittsburgh Sleep Quality Index [PSQI]) to classify them as worthy or not worthy of medical/pharmacological care. Serum DPP-4 was determined by Enzime Linked Immunosorbent Assay (ELISA). The statistical analysis was done in RStudio Software. Results: Fifty seven subjects (2017-2018) were included, with a combined frequency of overweight/obesity of 66.6% and with abdominal circumference values of 93.2 ± 13.6, higher than that proposed by the International Diabetes Federation. The PSQI was 8.3 ± 4.1, and 56.1% were classified as worthy of medical/pharmacological attention. When comparing the levels of DPP-4, these were higher in this group 2385.0 ± 2082.0 versus not worthy 1716.7 ± 1261.7 pg/mL, being statistically significant ( P  = 0.035). Conclusions: The elevated levels of DPP-4 in person with poor quality sleep worthy of medical/pharmacological treatment could be an early indicator of metabolic disorders, which need to be evaluated in depth.

Background: There was a need for a solid asthma guideline in Mexico to update and unify asthma management. Because high-quality asthma guidelines exist worldwide, in which the latest evidence on asthma management is summarized, the ADAPTE approach allows for the development of a national asthma guideline based on evidence from already existing guidelines, adapted to national needs., Objective: To fuse evidence from the best asthma guidelines and adapt it to local needs with the ADAPTE approach., Methods: The Appraisal of Guidelines for Research and Evaluation (AGREE) II asthma guidelines were evaluated by a core group to select 3 primary guidelines. For each step of asthma management, clinical questions were formulated and replied according to (1) evidence in the primary guidelines, (2) safety, (3) Cost, and (4) patient preference. The Guidelines Development Group, composed of a broad range of experts from medical specialties, primary care physicians, and methodologists, adjusted the draft questions and replies in several rounds of a Delphi process and 3 face-to-face meetings, taking into account the reality of the situation in Mexico. We present the results of the pediatric asthma treatment part., Results: Selected primary guidelines are from the British Thoracic Society and Scottish Intercollegiate Guidelines Network (BTS/SIGN), Global Initiative for Asthma (GINA), and Spanish Guidelines on the Management of Asthma (GEMA) 2015, with 2016 updates. Recommendations or suggestions were made for asthma treatment in Mexico. In this article, the detailed analysis of the evidence present in the BTS/SIGN, GINA, and GEMA sections on the (non) pharmacologic treatment of pediatric asthma, education, and devices are presented for 2 age groups: children 5 years or younger and children 6 to 11 years old with asthma., Conclusion: For the pediatric treatment and patient education sections, applying the AGREE II and Delphi methods is useful to develop a scientifically sustained document, adjusted to the Mexican situation, as is the Mexican Guideline on Asthma., (Copyright © 2018 American College of Allergy, Asthma & Immunology.

Background: With the availability of high-quality asthma guidelines worldwide, one possible approach of developing a valid guideline, without re-working the evidence, already analysed by major guidelines, is the ADAPTE approach, as was used for the development of National Guidelines on asthma., Methods: The guidelines development group (GDG) covered a broad range of experts from medical specialities, primary care physicians and methodologists. The core group of the GDG searched the literature for asthma guidelines 2005 onward, and analysed the 11 best guidelines with AGREE-II to select three mother guidelines. Key clinical questions were formulated covering each step of the asthma management., Results: The selected mother guidelines are British Thoracic Society (BTS), GINA and GEMA 2015. Responses to the questions were formulated according to the evidence in the mother guidelines. Recommendations or suggestions were made for asthma treatment in Mexico by the core group, and adjusted during several rounds of a Delphi process, taking into account: 1. Evidence; 2. Safety; 3. Cost; 4. Patient preference - all these set against the background of the local reality. Here the detailed analysis of the evidence present in BTS/GINA/GEMA sections on prevention and diagnosis in paediatric asthma are presented for three age-groups: children with asthma ≤5 years, 6-11 years and ≥12 years., Conclusions: For the prevention and diagnosis sections, applying the AGREE-II method is useful to develop a scientifically-sustained document, adjusted to the local reality per country, as is the Mexican Guideline on Asthma., (Copyright © 2017.

Background: The need for a national guideline, with a broad basis among specialists and primary care physicians was felt in Mexico, to try unifying asthma management. As several high-quality asthma guidelines exist worldwide, it was decided to select the best three for transculturation., Methods: Following the internationally recommended methodology for guideline transculturation, ADAPTE, a literature search for asthma guidelines, published 1-1-2007 through 31-12-2015 was conducted. AGREE-II evaluations yielded 3/40 most suitable for transculturation. Their compound evidence was fused with local reality, patient preference, cost and safety considerations to draft the guideline document. Subsequently, this was adjusted by physicians from 12 national medical societies in several rounds of a Delphi process and 3 face-to-face meetings to reach the final version., Results: Evidence was fused from British Thoracic Society Asthma Guideline 2014, Global Initiative on Asthma 2015, and Guía Española del Manejo del Asma 2015 (2016 updates included). After 3 Delphi-rounds we developed an evidence-based document taking into account patient characteristics, including age, treatment costs and safety and best locally available medication., Conclusions: In cooperation pulmonologists, allergists, ENT physicians, paediatricians and GPs were able to develop an evidence-based document for the prevention, diagnosis and treatment of asthma and its exacerbations in Mexico.

Background: Mucinous colloid lung adenocarcinoma is an uncommon variant of lung carcinomas with similar features to tumours seen in the gastrointestinal tract. To distinguish between these tumours and other mucinous lung tumours, such as mucinous bronchioloalveolar cell carcinomas and metastatic mucinous lesions could be difficult with small biopsy specimens from fine needle aspiration., Clinical Case: The case is described of a 49-year-old female with history of dyspnoea and cough with bloody sputum and weight lose. Thorax axial computed tomography demonstrated a right lower lobe spiculated mass with calcifications. Transthoracic computed tomography- guided fine needle biopsy reported negative results, and the biopsy obtained with video-assisted thoracic surgery was useful for an adequate cytology report of a colloid variant of mucinous lung adenocarcinoma., Conclusion: Video-assisted thoracic surgery is an appropriate option for obtaining a larger specimen in those cases where small biopsies are inconclusive for the diagnosis of thoracic pathologies such as malignant tumours., (Copyright © 2015 Academia Mexicana de Cirugía A.C.

Any asthmatic patient at risk of developing exacerbations in severity from mild to very severe and rarely ends in death. Some patients have poor perception of their symptoms and can have a very significant decrease in lung function without a significant change in its manifestations so that with the exception of children under five, it is essential to measure whether the bronchial obstruction by flujometry or spirometry. There are two stages in the progression of an exacerbation of asthma: slow-onset acute asthma or type I, when predominant airway inflammation and patients show clinical and functional deterioration in hours, days and sometimes weeks. This can be between 80 and 90% of exacerbations that occur in adults. The other scenario, less commonly, bronchospasm is caused predominantly by causing an acute exacerbation or type II changes from 3 to 6 hours. In this chapter some recommendations about the treatment of patients in crisis and emphasizes the steps to be taken in different scenarios.
