Early Modern English Scientific Manuscripts in the Hunterian Collection: A Physical Description of Gul, MS Hunter 135
2017
RESUMEN: El presente artículo ofrece un análisis codicológico y paleográfi co del manuscrito Hunter 135, un volumen del siglo XVI que contiene cinco tratados de los cuales el segundo y la mitad del tercero son objeto de estudio (chirvrgia libri, ff. 34r-73v; y medica qvaedam, ff. 74r-121v). La descripción física no solo ha permitido aportar la posible fecha de composición del manuscrito sino que también ha hecho posible el análisis de las técnicas en la producción de manuscritos en el Periodo moderno temprano (1500-1700).ABSTRACT: The present article provides a codicological and palaeographic analysis of MS Hunter 135, a sixteenth-century volume containing fi ve treatises, the second and appr…
Desire and its preternse: Analysis of Intersubjective relations in Frank Capra's It happened one night
2019
The following paper analyzes the plot of the 1934 film It Happened One Night, by Frank Capra, an authentic emblem within the film genre of romantic comedy. In it, the protagonists manage to overcome the obstacles that are offered in their way thanks to the pretense of a relationship, the marital one, which finally will end up becoming effective. Recalling a famous Lacanian sentence, according to which human beings “pretend to pretend”, the plot devised by Capra will be analyzed in order to go over the steps that sequence such pretenses. These give order to a process of maturity in which the characters will become what they represent, evidencing the sexual nature of the desire that had impel…
Pathogenesis and clinical relevance of bone marrow embolism in medullary nailing — demonstrated by intraoperative echocardiography
1993
Abstract For the clarification of pulmonary impairment after medullary nailing of femoral fractures, the intramedullary pressure in the femoral cavity during the operative procedure was investigated. In addition, an intraoperative transoesophageal echocardiography was performed which revealed two phenomena occurring once the intramedullary pressure had increased: snow-flurry and configured emboli. An experimental study in sheep was performed in order to define the substrata of the sonographic echoes. The level of intrafemoral pressure which would result in bone marrow intravasation and the substrata of the echocardiographic echoes were studied in sheep by applying pressure to the femoral ca…
Residual cardiovascular risk of lipid origin. Components and pathophysiological aspects
2019
Abstract There is no doubt about the relationship between LDL-C and cardiovascular risk, as well as about the benefits of statin treatment. Once the objective of LDL-C has been achieved, the evidences that demonstrate the persistence of a high cardiovascular risk, a concept called residual risk, are notable. The residual risk of lipid origin is based on atherogenic dyslipidemia, characterised by an increase in triglycerides and triglyceride-rich lipoproteins, a decrease in HDL-C and qualitative alterations in LDL particles. The most commonly used measures to identify this dyslipidemia are based on the determination of total cholesterol, triglycerides, HDL, non-HDL cholesterol and remaining …
Assessing transfusion practice in elective surgical patients: a baseline audit
2019
Background Externally generated hospital benchmarking data indicated that the blood transfusion rate within elective surgical orthopaedic and gastrointestinal patients at a metropolitan, tertiary healthcare facility was higher than comparable Australian hospitals. An investigation of transfusion practices was undertaken with the aim of understanding the reasons contributing to this higher incidence. Study Methods A chart audit was undertaken of every major, elective, surgical orthopaedic and gastrointestinal patient who received a blood transfusion between July and December 2017. The audit aimed to ascertain whether patients were screened and treated for preoperative anaemia and measure the…
Screw fixation of radial head fractures: Compression screw versus lag screw—A biomechanical comparison
2009
Abstract Introduction Secondary loss of reduction and pseudarthrosis due to unstable fixation methods remain challenging problems of surgical stabilisation of radial head fractures. The purpose of our study was to determine whether the 3.0 mm Headless Compression Screw (HCS) provides superior stability to the standard 2.0 mm cortical screw (COS). Materials and methods Eight pairs of fresh frozen human cadaveric proximal radii were used for this paired comparison. A standardised Mason II-Fracture was created with a fragment size of 1/3 of the radial head's articular surface that was then stabilised either with two 3.0 mm HCS (Synthes) or two 2.0 mm COS (Synthes) according to a randomisation …
Minimally invasive plate fixation in femoral shaft fractures
1997
Bridge-plating with its advantages in terms of vascularity and bone healing is a well established procedure today in the treatment of comminuted femoral fractures. Bridge-plating means that the fracture site is not interfered with during the operative procedure. This paper introduces a surgical technique in which the plate is inserted through isolated proximal and distal incisions only, behind the vastus lateralis. Alignment is secured by the plates, the fracture site remains untouched, fixation and screw insertion is restricted to the proximal and distal main fragments. Longitudinal femoral fractures extending right into the trochanteric and or condylar areas are the main indication for mi…
18F-FDG PET/CT in cardiovascular infection and inflammation.
2021
The diagnosis of cardiovascular infection and inflammation by [18F]FDG PET/CT in Nuclear Cardiology is of growing interest, because with respect to echocardiography this technique has improved the certainty in the diagnosis of infective endocarditis in patients with prosthetic valves, the increasing number of patients with implantable cardiac devices because of the progressive ageing of the population, as well as in patients with suspected large vessel vasculitis. All are serious clinical situations which require correct diagnosis and appropriate treatment as soon as possible, because they can cause severe complications, high mortality and also increased health care costs. We review the use…
Nonalcoholic fatty liver disease, association with cardiovascular disease and treatment. (I). Nonalcoholic fatty liver disease and its association wi…
2016
Non-alcoholic fatty liver disease (NAFLD) comprises a series of histologically lesions similar to those induced by alcohol consumption in people with very little or no liver damage. The importance of NAFLD is its high prevalence in the Western world and, from the point of view of the liver, in its gradual progression from steatosis to steatohepatitis, cirrhosis, and liver cancer. During the last decade it has been observed that NAFLD leads to an increased cardiovascular risk with acceleration of arteriosclerosis and events related to it, being the main cause of its morbidity and mortality. This review, updated to January 2016, consists of two parts, with the first part analysing the associa…
Nonalcoholic fatty liver disease, association with cardiovascular disease and treatment (II). The treatment of nonalcoholic fatty liver disease.

Disease nonalcoholic fatty liver disease (NAFLD) comprises a series of histologically similar to those induced by alcohol consumption in people with very little or no liver damage same. The importance of NAFLD is its high prevalence in our Western societies, from the point of view liver in its progressive evolution from steatosis to steatohepatitis, cirrhosis and liver cancer. During the last decade it has been observed that NAFLD leads to an increased cardiovascular risk with accelerated atherosclerosis and cardiovascular events, the leading cause of morbidity and mortality. This updated January 2016 revision consists of two parts. In this second part, the treatment of NAFLD and its influe…
