Small but smart: the interaction between environmental cues and internal state modulates host-patch exploitation in a parasitic wasp
2007
International audience; The reproductive success of insect parasitoids depends on two activities, searching for hosts to obtain immediate fitness rewards (offspring) and searching for food to extend life span and enhance future reproductive opportunities. Models suggest that to deal with this trade-off and to cope with the variability of the resources they depend on, parasitoids should simultaneously integrate information originating from three distinct sources: host and food availabilities in the environment (environmental information) and the metabolic reserves of the parasitoid (internal information). We tested whether, in the parasitic wasp Venturia canescens, these three types of infor…
Factors associated with nocturia-related quality of life in men with lower urinary tract symptoms and treated with tamsulosin oral controlled absorpt…
2020
Nocturia impairs quality of life (QoL). We have performed a non-interventional study in which men with lower urinary tract symptoms (LUTS) were treated for at least 3 months with tamsulosin oral controlled absorption system (0.4 mg q.d.). Other than observing efficacy and tolerability of this drug formulation, the study was designed to explore the relative roles of number of nocturia episodes and of non-urological causes of nocturia on nocturia-related QoL at baseline and treatment-associated changes thereof. The study enrolled 5775 men seeking treatment of their LUTS. Tamsulosin improved LUTS, e.g. International Prostate Symptom Score from 19.5 +/- 5.9 to 10.1 +/- 4.9 (means +/- SD). This …
La metamorfosis del río Turia en Valencia (1897-2016): de cauce torrencial urbano a corredor verde metropolitano
2017
La presente tesis estudia la profunda metamorfosis del cauce y las orillas del Turia a su paso por Valencia a lo largo del siglo XX y principios del XXI. En gran medida se ha producido de forma paralela a los cambios urbanos y metropolitanos. Esta simultaneidad de interrelaciones entre río y ciudad no representa un caso aislado, sino que plasma muchas de las problemáticas que aquel binomio plantea en el ambiente mediterráneo español (escasez de recursos, prácticas abusivas, contaminación y deterioro ambiental, principalmente). Sin embargo, la gestión del Turia durante la fase más tecnocrática del franquismo ha acarreado consecuencias territoriales y conflictos específicos que merecen ser de…
Desmopressin in the Treatment of Nocturia: A Double-Blind, Placebo-Controlled Study
2007
Objectives: To investigate efficacy, safety, and impact on quality of sleep of desmopressin in the treatment of nocturia. Methods: Adults aged >= 18 yr with nocturia (>= 2 voids/night) received desmopressin tablets (0.1, 0.2, or 0.4 mg) during a 3-wk dose-titration period. Patients should show sufficient response during the dose-titration period (>= 20% reduction in nocturnal diuresis) and a return of nocturnal diuresis to >= 80% of baseline levels during washout. Eligible patients then entered a 3-wk double-blind treatment period and received either desmopressin or placebo. Results: 127 patients were randomised to either desmopressin (n = 61) or placebo (n = 66). Twenty (33%) desmopressin-…
Virtual Unenhanced Images at Dual-Energy CT: Influence on Renal Lesion Characterization
2019
Background Dual-energy (DE) CT allows reconstruction of virtual noncontrast (VNC) images from a single-phase contrast agent-enhanced examination, potentially reducing the need for multiphasic CT to characterize renal lesions. However, data regarding diagnostic performance of VNC images for the characterization of renal lesions are limited. Purpose To determine whether renal mass CT performed by using VNC images allows for reliable identification of renal lesions and differentiation of contrast-enhanced from unenhanced lesions, compared with unenhanced images. Materials and Methods This is a retrospective study of 293 patients (105 women [mean age, 65 years; age range, 18-91 years] and 188 m…
Sleep-wake disturbances in patients with amyotrophic lateral sclerosis
2011
Objective To evaluate the frequency, severity and determinants of sleep disturbances in patients with amyotrophic lateral sclerosis (ALS). Methods Information about night-time complaints was collected using a standardised questionnaire, the Pittsburgh Sleep Quality Index (PSQI), and the Epworth Sleepiness Scale (ESS) in a group of 100 patients with ALS and in 100 control subjects matched for age and sex. Functional disability was assessed using the ALS Functional Rating Scale-Revised (ALSFRS-R). Sleep was studied by overnight polysomnography in 12 patients. Results Fifty-nine patients with ALS and 36 controls reported sleep disturbances. The mean global PSQI score of patients with ALS was s…
Trends and Prevalence of Nocturia Among US Adults, 2005-2016
2019
Purpose: Increased nocturia episodes can be a clinical marker of poor health status. The present study aimed to evaluate patterns and temporal trends in nocturia and sociodemographic and lifestyle correlates in the US population. Methods: Participants, aged 20 years or older, were included in this repeated cross-sectional study. The National Health and Nutrition Examination Survey from 2005 to 2016 was used. Participants were asked “During the past 30 days, how many times per night did you most typically get up to urinate, from the time you went to bed at night until the time you got up in the morning?”. Individuals were categorized as either ≥ 1 nocturia episode or ≥ 2 nocturia episodes pe…
Population-based survey of urinary incontinence, overactive bladder, and other lower urinary tract symptoms in five countries: results of the EPIC st…
2006
Abstract Objective Estimate the prevalence of urinary incontinence (UI), overactive bladder (OAB), and other lower urinary tract symptoms (LUTS) among men and women in five countries using the 2002 International Continence Society (ICS) definitions. Methods This population-based, cross-sectional survey was conducted between April and December 2005 in Canada, Germany, Italy, Sweden, and the United Kingdom using computer-assisted telephone interviews. A random sample of men and women aged ≥ 18 yr residing in the five countries and who were representative of the general populations in these countries was selected. Using 2002 ICS definitions, the prevalence estimates of storage, voiding, and po…
Transposition of the left renal vein for treatment of the nutcracker phenomenon: long-term follow-up
2002
Abstract Objectives To assess the therapeutic value of left renal vein transposition for treatment of the nutcracker phenomenon in long-term follow-up. Methods Eight patients (4 women and 4 men) between 23 and 58 years old (mean 39.1) underwent transposition of the left renal vein for treatment of the nutcracker phenomenon associated with recurrent gross hematuria and flank pain. The postoperative follow-up was 41 to 136 months (mean 66.4). Results No perioperative complications were encountered. The postoperative complications comprised deep vein thrombosis (n = 1), retroperitoneal hematoma necessitating surgical revision (n = 1), and paralytic ileus that resolved with conservative managem…
The Nutcracker Syndrome: New Aspects of Pathophysiology, Diagnosis and Treatment
1991
Magnetic resonance imaging (MRI) was used to study vascular anatomy in 3 patients with the nutcracker syndrome and in 10 healthy volunteers. From these studies an abnormal branching of the superior mesenteric artery from the aorta was identified as being the cause of the nutcracker syndrome. Consequently, surgical transposition of the left renal vein to achieve an unobstructed renal venous backflow was performed successfully in 2 patients, while 1 underwent nephrectomy. In 1 patient adjuvant ureteral instrumentation became necessary to aid occlusion of persisting shunts between peripelvic venous varicosities and the urinary tract. Awareness of the pathophysiology of the nutcracker syndrome …
