Estudio comparativo de la acotación de una línea de ejes de un buque mediante tolerancias dimensionales y geométricas conforme a normativa ISO

[Resumen] Dado que, como ya es sabido, ningún proceso de fabricación mecánica puede alcanzar la exactitud absoluta, hemos de fabricar los elementos constructivos con un rango de incertidumbre adecuado dentro de aquellos aceptados para llevar a buen término el proyecto de ejecución del buque. Estos rangos aceptados lo son por fuentes de reconocido prestigio; Sociedades de Clasificación, por una parte, normas internacionales y nacionales por otra. Estos rangos son las tolerancias de fabricación aplicadas a los elementos constructivos objeto del presente TFG. Por todo ello, el dibujo mecánico especializado aquí como dibujo naval en sus dos niveles; la representación del proyectista y la interpretación del ejecutante del proyecto es y será motor de éxito en la consecución del proyecto constructivo naval.Traballo fin de grao (UDC.ETSNEM).

Role of age and comorbidities in mortality of patients with infective endocarditis

[Purpose]: The aim of this study was to analyse the characteristics of patients with IE in three groups of age and to assess the ability of age and the Charlson Comorbidity Index (CCI) to predict mortality. [Methods]: Prospective cohort study of all patients with IE included in the GAMES Spanish database between 2008 and 2015.Patients were stratified into three age groups:<65 years,65 to 80 years,and ≥ 80 years.The area under the receiver-operating characteristic (AUROC) curve was calculated to quantify the diagnostic accuracy of the CCI to predict mortality risk. [Results]: A total of 3120 patients with IE (1327 < 65 years;1291 65-80 years;502 ≥ 80 years) were enrolled.Fever and heart failure were the most common presentations of IE, with no differences among age groups.Patients ≥80 years who underwent surgery were significantly lower compared with other age groups (14.3%,65 years; 20.5%,65-79 years; 31.3%,≥80 years). In-hospital mortality was lower in the <65-year group (20.3%,<65 years;30.1%,65-79 years;34.7%,≥80 years;p < 0.001) as well as 1-year mortality (3.2%, <65 years; 5.5%, 65-80 years;7.6%,≥80 years; p = 0.003).Independent predictors of mortality were age ≥ 80 years (hazard ratio [HR]:2.78;95% confidence interval [CI]:2.32–3.34), CCI ≥ 3 (HR:1.62; 95% CI:1.39–1.88),and non-performed surgery (HR:1.64;95% CI:11.16–1.58).When the three age groups were compared,the AUROC curve for CCI was significantly larger for patients aged <65 years(p < 0.001) for both in-hospital and 1-year mortality. [Conclusion]: There were no differences in the clinical presentation of IE between the groups. Age ≥ 80 years, high comorbidity (measured by CCI),and non-performance of surgery were independent predictors of mortality in patients with IE.CCI could help to identify those patients with IE and surgical indication who present a lower risk of in-hospital and 1-year mortality after surgery, especially in the <65-year group

Development of an application for mobile phones (App) based on the collaboration between the Spanish Society of Rheumatology and Spanish Society of Family Medicine for the referral of systemic autoimmune diseases from primary care to rheumatology

El diagnóstico y tratamiento de las enfermedades autoinmunes sistémicas (EAS) constituye un reto. Aunque infrecuentes, afectan a cientos de miles de pacientes en España. El médico de familia (MF) se enfrenta a síntomas o signos inespecíficos que hacen sospechar EAS al inicio del proceso, y tiene que decidir a quiénes debería derivar. Para facilitar su reconocimiento y mejorar su derivación, expertos de la Sociedad Española de Medicina de Familia y Comunitaria y de la Sociedad Española de Reumatología seleccionaron 26 síntomas/signos-guía y alteraciones analíticas. Se escogieron parejas de MF y reumatólogo para elaborar algoritmos diagnósticos y de derivación. Posteriormente se revisaron y adaptaron al formato de aplicación para móviles (app) descargable. El resultado es el presente documento de derivación de EAS para MF en formato de papel y app. Contiene algoritmos de fácil manejo utilizando datos de la anamnesis, exploración física y pruebas analíticas accesibles en atención primaria para orientar el diagnóstico y facilitar la derivación a reumatología o a otras especialidades.Management of systemic autoimmune diseases is challenging for physicians in their clinical practice. Although not common, they affect thousands of patients in Spain. The family doctor faces patients with symptoms and non-specific cutaneous, mucous, joint, vascular signs or abnormal laboratory findings at the start of the disease process and has to determine when to refer patients to the specialist. To aid in disease detection and better referral, the Spanish Society of Rheumatology and the Spanish Society of Family Medicine has created a group of experts who selected 26 symptoms, key signs and abnormal laboratory findings which were organized by organ and apparatus. Family doctors and rheumatologists with an interest in autoimmune systemic diseases were selected and formed mixed groups of two that then elaborated algorithms for diagnostic guidelines and referral. The algorithms were then reviewed, homogenized and adapted to the algorithm format and application for cell phone (apps) download. The result is the current Referral document of systemic autoimmune diseases for the family doctor in paper format and app (download). It contains easy-to-use algorithms using data from anamnesis, physical examination and laboratory results usually available to primary care, that help diagnose and refer patients to rheumatology or other specialties if needed.Sin financiaciónNo data JCR 20200.271 SJR (2020) Q4, 50/58 RheumatologyNo data IDR 2020UE

Evolution over Time of Ventilatory Management and Outcome of Patients with Neurologic Disease∗

OBJECTIVES: To describe the changes in ventilator management over time in patients with neurologic disease at ICU admission and to estimate factors associated with 28-day hospital mortality. DESIGN: Secondary analysis of three prospective, observational, multicenter studies. SETTING: Cohort studies conducted in 2004, 2010, and 2016. PATIENTS: Adult patients who received mechanical ventilation for more than 12 hours. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: Among the 20,929 patients enrolled, we included 4,152 (20%) mechanically ventilated patients due to different neurologic diseases. Hemorrhagic stroke and brain trauma were the most common pathologies associated with the need for mechanical ventilation. Although volume-cycled ventilation remained the preferred ventilation mode, there was a significant (p &lt; 0.001) increment in the use of pressure support ventilation. The proportion of patients receiving a protective lung ventilation strategy was increased over time: 47% in 2004, 63% in 2010, and 65% in 2016 (p &lt; 0.001), as well as the duration of protective ventilation strategies: 406 days per 1,000 mechanical ventilation days in 2004, 523 days per 1,000 mechanical ventilation days in 2010, and 585 days per 1,000 mechanical ventilation days in 2016 (p &lt; 0.001). There were no differences in the length of stay in the ICU, mortality in the ICU, and mortality in hospital from 2004 to 2016. Independent risk factors for 28-day mortality were age greater than 75 years, Simplified Acute Physiology Score II greater than 50, the occurrence of organ dysfunction within first 48 hours after brain injury, and specific neurologic diseases such as hemorrhagic stroke, ischemic stroke, and brain trauma. CONCLUSIONS: More lung-protective ventilatory strategies have been implemented over years in neurologic patients with no effect on pulmonary complications or on survival. We found several prognostic factors on mortality such as advanced age, the severity of the disease, organ dysfunctions, and the etiology of neurologic disease
