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 …
Atteinte de la Muscularis Mucosae dans les tumeurs urothéliales T1 de vessie : facteur pronostique de progression après immunothérapie par BCG
2012
OBJECTIVES: To study the prognostic impact of muscularis mucosae (MM) invasion for pT1 bladder cancer treated by transurethral resection (TUR) and adjuvant Bacille Calmette-Guerin (BCG) intravesical immunotherapy. METHODS: Sixty-six patients treated by BCG intravesical instillations were substaged into pT1a and pT1b, regarding Muscularis Mucosae invasion. Tumor grade, associated carcinoma in situ (CIS), multifocality, tumoral size up to 3cm, BCG maintenance were noted. With a mean follow-up of 50.5±38 months, we studied recurrence, progression, overall and specific survival. Cox's model method was used for multivariate analysis. RESULTS: Tumor recurrence was observed in 30±7% and 43±10% (P=…
Use of multiparametric magnetic resonance imaging and fusion-guided biopsies to properly select and follow African-American men on active surveillance
2019
OBJECTIVES To determine the rate of Gleason Grade Group (GGG) upgrading in African-American (AA) men with a prior diagnosis of low-grade prostate cancer (GGG 1 or GGG 2) on 12-core systematic biopsy (SB) after multiparametric magnetic resonance imaging (mpMRI) and fusion biopsy (FB); and whether AA men who continued active surveillance (AS) after mpMRI and FB fared differently than a predominantly Caucasian (non-AA) population. PATIENTS AND METHODS A database of men who had undergone mpMRI and FB was queried to determine rates of upgrading by FB amongst men deemed to be AS candidates based on SB prior to referral. After FB, Kaplan-Meier curves were generated for AA men and non-AA men who th…
Myogenic effects enhance norepinephrine constriction: Inhibition by nitric oxide and felodipine
1998
Myogenic effects enhance norepinephrine constriction: Inhibition by nitric oxide and felodipine. Myogenic, pressure-induced vasoconstriction may amplify the effects of circulating vasoconstrictors. Through intravital microscopy in cremaster arterioles (31 to 115 μm diameter), the relative contribution of myogenic responses (MR) to norepinephrine (NE)-induced constriction and the inhibitor potency of nitric oxide (NO) or a Ca2+ entry blocker (CEB), felodipine (F), were examined. In 24 anesthetized hamsters, a vessel occluder was placed around the aorta to control cremaster vessel inflow pressure (IP). NE infusion increased blood pressure (by 50 ± 2mm Hg) and induced significant constriction …
Blood pressure in chronic kidney disease stage 5D—report from a Kidney Disease: Improving Global Outcomes controversies conference
2010
Management of blood pressure (BP) in patients with chronic kidney disease receiving dialysis (stage 5D) provides a significant challenge for healthcare professionals. The association between BP and cardiovascular disease risk has been well studied in the general population; however, in dialysis patients, physiological and dialysis-related mechanisms influencing BP are complex, and the associated risk is poorly understood. In stage 5D, BP is determined by the complex interplay of fluid volume and prescription of post-dialysis target weight, sodium load, the renin–angiotensin and sympathetic nervous systems, and diverse exogenous factors, such as administration of erythropoiesis-stimulating a…
Prevalence and Associated Factors of Erectile Dysfunction among Married Men in Vietnam
2017
Background Sexuality is an essential part of life; however, erectile dysfunction (ED) has been one of the most common complaints among men with sexual health issues all over the world. ED includes dysfunction in erection and penile erectile pain. In Vietnam, ED is a subject a not readily discussed. Thus, relatively little is known about ED among Vietnamese men. Aims To identify the prevalence of ED and its associated variables and the need for treatment of ED among married men in Vietnam. Methods This was a cross-sectional study. A total sample size included 746 married men, aged 20–60 years, living in four representative wards of the Hue City and randomly selected by systematic sampling me…
Needs Assessment in Care of Adults With Anorectal Malformations and Exstrophy-Epispadias Complex in Germany
2018
Introduction: Medical needs of adults with anorectal malformations (ARM) and the exstrophy-epispadias complex (EEC) are not fully understood. Therefore, the aim of the study was to evaluate how affected individuals get along with the current national medical care and what their medical or social long-term requirements are. Patients and Methods: Between 11/2014-07/2016 all adult members (≥18 years, ARM n = 113, EEC n = 126) of the German self-help organizations SoMA e.V. and Blasenekstrophie/Epispadie e.V. were contacted via email or post and asked to fill out an anonymous online questionnaire regarding medical requirements, treatment satisfaction, daily life impairment and expectations rega…
Neutrophil Gelatinase-Associated Lipocalin for Acute Kidney Injury During Acute Heart Failure Hospitalizations
2016
AbstractBackground: Worsening renal function (WRF) often occurs during acute heart failure (AHF) and can portend adverse outcomes; therefore, early identification may help mitigate risk. Neutrophil...
Intra-Dialytic Electrostimulation of Leg Extensors May Improve Exercise Tolerance and Quality of Life in Hemodialyzed Patients
2011
Hemodialyzed (HD) patients with end-stage renal disease (ESRD) exhibit lower fitness as a consequence of chronic uremic changes that trigger various structural, metabolic, and functional abnormalities in skeletal muscles. The aim of this randomized study was to compare the effect of rehabilitation (RHB) training on a bicycle ergometer and electromyostimulation (EMS) of leg extensors in HD patients with ESRD. Thirty-two HD patients (18 men/14 women; mean age 61.1 ± 8.8 years) were randomized into three groups: (i) exercise training (ET; n = 11) on bicycle ergometer 2 × 20 min; (ii) EMS (n = 11) where stimulation (10 Hz) of leg extensors was applied for 60 min; and (iii) controls (CON; n = 10…
What influence patients'choice for peritoneal dialysis? a qualitative study
2018
L’objectif de cette étude était d’identifier les facteurs qui influencent le choix de la dialyse péritonéale (DP) chez les patients insuffisants rénaux, dans un centre de dialyse en France offrant un dispositif d’éducation thérapeutique du patient (ETP) aux patients en pré-dialyse. Pour ce faire, nous avons mené trente six entretiens semi-directifs avec des patients, des médecins de l’équipe d’ETP et un cadre de santé. Nous avons également observé dix séances d’ETP afin d’explorer la nature des interactions entre les patients, leurs accompagnants et l’équipe soignante. Nos résultats révèlent que les facteurs qui poussent les patients à choisir la DP sont l’influence des proches, les préfére…
