Dos terapias conocidas podrían ser efectivas como adyuvantes en el paciente crítico infectado por COVID-19
2020
Resumen La neumonia causada por coronavirus, que se origino en Wuhan, China, a finales de 2019, se ha extendido por todo el mundo convirtiendose en una pandemia. Desafortunadamente, a dia de hoy no existe ninguna vacuna especifica para el virus COVID-19, y el tratamiento esta siendo de soporte con anadido de antivirales y otros farmacos, sin que hasta la fecha se haya evidenciado un beneficio claro. Muchos de estos pacientes se deterioran rapidamente y requieren ser intubados y ventilados mecanicamente, lo que esta provocando el colapso del sistema sanitario en muchos paises debido a la falta de ventiladores y de camas de criticos. En este documento revisamos dos terapias adyuvantes sencill…
Intracortical facilitation within the migraine motor cortex depends on the stimulation intensity. A paired-pulse TMS study
2018
Abstract Introduction Connectivity within the primary motor cortex can be measured using the paired-pulse transcranial magnetic stimulation (TMS) paradigm. This evaluates the effect of a first conditioning stimulus on the motor evoked potential (MEP) elicited by a second test stimulus when different interstimulus intervals are used. Aim of the present study was to provide, in patients suffering from migraine without aura (MwoA), additional information on intracortical facilitation (ICF), short intracortical inhibition (SICI), and long intracortical inhibition (LICI), using different intensities of the test stimulus (TS). Methods We enrolled 24 patients with episodic MwoA and 24 age- and sex…
Dying with or because of invasive fungal infection? The role of immunity exhaustion on patient outcome
2016
De Rosa et al. considered clinical scores, biomarkers and their combination as useful aids for an early antifungal treatment and advocated the adoption of de-escalation therapy in an antifungal stewardship approach as a possible key for a better management of these patients. Authors considered the high burden of invasive fungal infections in terms of patient outcomes and costs and focused on current strategies for their optimization.
Uptake of hysterectomy and bilateral salpingo-oophorectomy in carriers of pathogenic mismatch repair variants:a Prospective Lynch Syndrome Database r…
2021
Purpose: This study aimed to report the uptake of hysterectomy and/or bilateral salpingo-oophorectomy (BSO) to prevent gynaecological cancers (risk-reducing surgery [RRS]) in carriers of pathogenic MMR (path_MMR) variants.Methods: The Prospective Lynch Syndrome Database (PLSD) was used to investigate RRS by a cross-sectional study in 2292 female path_MMR carriers aged 30-69 years.Results: Overall, 144, 79, and 517 carriers underwent risk-reducing hysterectomy, BSO, or both combined, respectively. Two-thirds of procedures before 50 years of age were combined hysterectomy and BSO, and 81% of all procedures included BSO. Risk-reducing hysterectomy was performed before age 50 years in 28%, 25%,…
Infrared microspectroscopic determination of collagen cross-links in articular cartilage
2017
Collagen forms an organized network in articular cartilage to give tensile stiffness to the tissue. Due to its long half-life, collagen is susceptible to cross-links caused by advanced glycation end-products. The current standard method for determination of cross-link concentrations in tissues is the destructive high-performance liquid chromatography (HPLC). The aim of this study was to analyze the cross-link concentrations nondestructively from standard unstained histological articular cartilage sections by using Fourier transform infrared (FTIR) microspectroscopy. Half of the bovine articular cartilage samples ( n = 27 ) were treated with threose to increase the collagen cross-linking whi…
Perfiles de resistencia y factores de riesgo de microorganismos resistentes en bacteriemia de origen abdominal
2017
Resumen Objetivo La presencia de microorganismos resistentes es una causa importante de fallo en el tratamiento antimicrobiano inicial. Los objetivos de este estudio son conocer el perfil de resistencia de los microorganismos causantes de bacteriemia de origen abdominal e identificar si el uso previo de antibioticos y el lugar de adquisicion de la bacteriemia son factores de riesgo para determinar la presencia de microorganismos resistentes. Material y metodo Se diseno un estudio de cohorte retrospectiva de todos los pacientes adultos que presentaron bacteriemia y/o fungemia cuyo foco infeccioso primario fue de origen abdominal ingresados en un hospital universitario durante los anos 2011-2…

Se identificaron los pacientes con hemocultivo positivo. Se encontro asociacion estadisticamente signific…
Stromal hyaluronan accumulation is associated with low immune response and poor prognosis in pancreatic cancer
2021
AbstractHyaluronan (HA) accumulation has been associated with poor survival in various cancers, but the mechanisms for this phenomenon are still unclear. The aim of this study was to investigate the prognostic significance of stromal HA accumulation and its association with host immune response in pancreatic ductal adenocarcinoma (PDAC). The study material consisted of 101 radically treated patients for PDAC from a single geographical area. HA staining was evaluated using a HA-specific probe, and the patterns of CD3, CD8, CD73 and PD-L1 expression were evaluated using immunohistochemistry. HA staining intensity of tumour stromal areas was assessed digitally using QuPath. CD3- and CD8-based …
Triptans and CGRP blockade - impact on the cranial vasculature.
2017
Abstract The trigeminovascular system plays a key role in the pathophysiology of migraine. The activation of the trigeminovascular system causes release of various neurotransmitters and neuropeptides, including serotonin and calcitonin gene-related peptide (CGRP), which modulate pain transmission and vascular tone. Thirty years after discovery of agonists for serotonin 5-HT1B and 5-HT1D receptors (triptans) and less than fifteen after the proof of concept of the gepant class of CGRP receptor antagonists, we are still a long way from understanding their precise site and mode of action in migraine. The effect on cranial vasculature is relevant, because all specific anti-migraine drugs and mig…
