Transfemoral Transcatheter Tricuspid Valve Replacement With the EVOQUE System

2021

Abstract Objectives The purpose of this observational first-in-human experience was to investigate the feasibility and safety of the EVOQUE tricuspid valve replacement system and its impact on short-term clinical outcomes. Background Transcatheter tricuspid intervention is a promising option for selected patients with severe tricuspid regurgitation (TR). Although transcatheter leaflet repair is an option for some, transcatheter tricuspid valve replacement (TTVR) may be applicable to a broader population. Methods Twenty-five patients with severe TR underwent EVOQUE TTVR in a compassionate-use experience. The primary outcome was technical success, with NYHA (NYHA) functional class, TR grade, …

2020

Background In March 2020, the World Health Organization (WHO) declared the COVID-19 pandemic and, a few days later, the Spanish Government declared a State of Emergency and the population lockdown. This crisis situation crisis forced deep changes in health care. At dental care level, it became necessary for both public health services and private consultations to plan changes to enable them to face this healthcare challenge. Material and methods SESPO and the General Council of Dentists of Spain (CGDE) appointed a Working Group to prepare a protocol for dental clinics after the lockdown stage. Continuing with this teamwork task, a series of recommendations addressed to public health manager…

A Mindfulness-Based Program Improves Health in Caregivers of People with Autism Spectrum Disorder: a Pilot Study

2014

Mindfulness-based interventions have demonstrated to be effective in reducing stress and health complaints in clinical populations. However, to our knowledge, biological health markers have not been used in studies of the effectiveness of mindfulness programs in caregivers of people with autism spectrum disorders (ASDs). This study aimed to assess the effects of a mindfulness intervention on mood disturbances and health complaints in this population compared with non-caregivers. The design of the study was quasi-experimental, with repeated measures. Self-reported health, cortisol awakening response (CAR), and afternoon cortisol levels before and after a mindfulness session were assessed at …

Survival of patients with gastric lymphoma in Germany and in the United States

2015

Background and Aim This study aims to examine survival for gastric lymphomas and its main subtypes, mucosa-associated lymphoid tissue lymphoma (MALT), and diffuse large B-cell lymphoma (DLBCL), in Germany and in the United States. Methods Data for patients diagnosed in 1997–2010 were used from 10 population-based German cancer registries and compared to the data from the US Surveillance, Epidemiology and End Results (SEER) 13 registries database. Patients age 15–74 diagnosed with gastric lymphomas were included in the analysis. Period analysis and modeled period analysis were used to estimate 5-year and 10-year relative survival (RS) in 2002–2010 and survival trends from 2002–2004 to 2008–2…

PNPLA3 polymorphism influences liver fibrosis in unselected patients with type 2 diabetes

2011

Context: Recently, it has been shown that an allele in the adiponutrin (PNPLA3) gene was strongly associated with increased liver fat content (LFC) and liver fibrosis independent of visceral adiposity and insulin resistance. Objective: In this study, we set out to determine whether the PNPLA3 rs738409 polymorphism was associated with liver fibrosis in unselected patients with type 2 diabetes. Design, setting and participants: Two hundred and thirty-four patients with type 2 diabetes were included in this study. Main outcome measures: LFC was evaluated using 1H-MR spectroscopy; fibrosis was measured using the non-invasive FibroTest®. Results: Advanced liver fibrosis (stage F2 or above) was o…

Peginterferon alfa-2b plus weight-based ribavirin for 24 weeks in patients with chronic hepatitis C virus genotype 1 with low viral load who achieve …

2011

Summary.  In chronic hepatitis C (CHC), treatment duration may be individualized according to time to first undetectable hepatitis C virus (HCV) RNA, with patients who attain undetectable HCV RNA early in treatment being candidates for shorter regimens. The aim of this study was to determine the relapse rate in patients with CHC genotype (G) 1 infection and low baseline viral load who achieved undetectable HCV RNA by week 4 [rapid virologic response (RVR)] when treated for 24 weeks. This was an open-label, multicentre, noninterventional study. Adult patients with G1 CHC infection and baseline viral load <600,000 IU/mL who attained RVR were treated with peginterferon alfa-2b (1.5 μg/kg/week)…

Recognition and characterization of small colonic neoplasia with high-definition colonoscopy using i-Scan is as precise as chromoendoscopy

2010

Abstract Background The EPKi system (Pentax, Japan) enables resolution above HDTV. Aim of the study was to test the efficacy of HD+ alone and with the new post-processing digital filter i-Scan or chromoendoscopy (Methylene blue 0.1%) in screening for colorectal cancer. We focused on lesions less than 5 mm as a surrogate marker for the optical possibilities of the EPKi system. Methods The last 30 cm of the colon in a screening population were inspected with HD+ alone, in combination with i-Scan (2:1 randomisation) and subsequently with chromoendoscopy. All lesions were characterized and targeted biopsies were performed. Results i-Scan augmented in 69 patients the identification of lesions fr…

Osteoporosis, densidad mineral ósea y complejo CKD-MBD (II): implicaciones terapéuticas

2019

Resumen: La osteoporosis (OP) y la enfermedad renal crónica (ERC) influyen independientemente en la salud ósea. Numerosos pacientes con ERC presentan una disminución de densidad mineral ósea (DMO), un elevado riesgo de fracturas por fragilidad ósea y un incremento de su morbimortalidad. Con el envejecimiento de la población estos hechos no son dependientes solo de la «osteodistrofia renal» sino también de la OP asociada. Dado que la DMO tiene capacidad predictiva en pacientes con ERC (parte I), ahora analizaremos las implicaciones terapéuticas derivadas. Análisis post hoc de estudios aleatorizados han mostrado que fármacos como alendronato, risedronato, raloxifeno, teriparatida o denosumab …

Right/Left Ventricular Blood Pool T2 Ratio as an Innovative Cardiac MRI Screening Tool for the Identification of Left‐to‐Right Shunts in Patients Wit…

2021

Background Left-to-right (L-R) shunts are characterized by a pathological connection between high- and low-pressure systems, leading to a mixing of oxygen-rich blood with low oxygenated blood. They are typically diagnosed by phase-contrast cardiac magnetic resonance imaging (MRI) which requires extensive planning. T2 is sensitive to blood oxygenation and may be able to detect oxygenation differences between the left (LV) and right ventricles (RV) caused by L-R shunts. Purpose To test the feasibility of routine T2 mapping to detect L-R shunts. Study type Retrospective. Population Patients with known L-R shunts (N = 27), patients with RV disease without L-R shunts (N = 21), and healthy volunt…

Bortezomib Retreatment in Relapsed Multiple Myeloma (MM): Results from a Binational, Multicenter Retrospective Survey

2008

Abstract In myeloma therapy retreatment after successful therapy is frequently considered. Here we present pooled data from a German and Swiss multicenter, retrospective survey (26866138MMY4014). The survey started in Germany and was later extended to Switzerland. German data have already been published before. Here we report on the entire cohort of patients for the first time. For inclusion into this analysis, patients with MM had to have had preceding bortezomib treatment, resulting in at least partial remission and a second therapy with Bortezomib on relapse. The intention of this trial was to provide further evidence of the value of a retreatment with bortezomib, description of predispo…
