Differences in ground reaction forces and shock impacts between nordic walking and walking.
2014
The regular practice of Nordic walking (NW) has increased in recent years, in part thanks to the health benefits described by the scientific literature. However, there is no consensus on the effects of shock-impact absorption during its practice. Purpose: The aim of this study was to compare the levels of impact and ground reaction forces (GRF) between NW and walking (W). Method: Twenty physically active and experienced participants were assessed using a dynamometric platform and accelerometry analysis. Results: The results show statistically significantly higher levels of acceleration in the tibia (12%) and head (21%) during NW compared with W. Equally, GRF were significantly higher (27%) …
Renal plasma flow, filtration fraction and microalbuminuria in hypertensive patients: Effects of chronic smoking
2005
SUMMARY: Introduction: Albumin excretion rate is usually increased in people who smoke, but the physiological basis of this phenomenon is not fully understood. Methods: The effect of chronic smoking on renal haemodynamics was studied in a cohort of 66 men. Twenty-seven were smokers and 36 were hypertensive. In all subjects, the albumin excretion rate was evaluated; in hypertensive patients, a renoscintigraphic evaluation of renal plasma flow and glomerular filtration were carried out and the filtration fraction was calculated. Results: The hypertensive smoking population presented an increased urinary albumin excretion rate in comparison with hypertensive non-smoking patients. No signifi…
Sympathetic Activity and Blood Pressure Pattern in Autosomal Dominant Polycystic Kidney Disease Hypertensives
1998
To study the potential role of sympathetic activity in the pathogenesis of arterial hypertension associated with autosomal dominant polycystic kidney disease (ADPKD) and to analyze its relationship with 24-hour blood pressure pattern, plasma catecholamines and 24-hour ambulatory blood pressure monitoring were evaluated in 30 ADPKD hypertensive patients (of which 17 without and 13 with renal failure) and in 50 essential hypertensives. The groups were matched for sex, body mass index, known duration of hypertension, and clinic blood pressure. Plasma catecholamines, determined in resting position, were higher in ADPKD patients without renal failure than in essential hypertensives. Nighttime di…
Brain Slow Potentials Reflecting Successful Shooting Performance
1995
Preparatory brain activity from frontal, centro-lateral, and occipital areas were recorded from top-level rifle shooters during shooting performance. The aim of the study was to examine the relation of brain slow potentials to qualitative (rifle holding) and quantitative (hit) aspects of superior shooting performance. For this purpose, a typology of slow potentials (SPs) was developed. The resulting SP types were used for unraveling the associations between the electrocortical activity and behavioral output. The main finding was that frontal positivity was associated with successful performance, but only if the central-right SP was more negative than the central-left one. This finding was e…
Relapsing and Progressive Complications of Severe Hypertriglyceridemia: Effective Long-Term Treatment with Double Filtration Plasmapheresis
2019
<b><i>Background:</i></b> Severe hypertriglyceridemia (HTG) is associated with major complications such as acute or relapsing pancreatitis (AP) and atherosclerotic cardiovascular disease (ASCVD). Rapid elimination of triglyceride (TG)-rich lipoproteins (LP) with double filtration plasmapheresis (DFPP) without need for substitution has been found to be effective for the acute, short-term treatment of HTG-induced AP. Data on the long-term use of DFPP to prevent HTG-associated complications are scarce. <b><i>Objectives:</i></b> To evaluate the use and efficacy of regular DFPP treatment in clinical practice for preventing recurrence of HTG-associa…
Ice water test in multiple sclerosis: A pilot trial.
2018
OBJECTIVES To investigate the significance of the ice water test in patients with multiple sclerosis and to evaluate a novel ice water test nomogram in a large patient cohort. METHODS A total of 201 ice water tests of patients with multiple sclerosis were retrospectively evaluated. Incontinence episodes in 24 h and sex were correlated with the ice water test. Furthermore, an ice water test nomogram was developed in order to categorize the detrusor overactivity in severity degrees. Descriptive statistics were carried out for population characteristics. Correlations of categorical variables were calculated by the χ2 -test. The independent t-test was carried out for correlations of continuous …
Focal therapy in localised prostate cancer: Real-world urological perspective explored in a cross-sectional European survey
2018
Introduction: The urological community's opinion over focal therapy (FT) for prostate cancer (PCa) has never been assessed. Our aim was to investigate the current opinion on FT in the European urological community. Methods: A 25 -item questionnaire was devised according to the Cherries checklist and distributed through SurveyMonkey using a web link from November 2016 to October 2017. After a pilot validation (n=40 urologists), the survey was sent through EAU and 9 other national European urological societies mailing list. Twitter was also used. Results: We received 484 replies from 51 countries. Almost half (44.8%, n=217) stated FT would represent a step forward, and 52.0% (n=252) would sug…
Treatment of cT1a Renal Tumours in Germany: A Nationwide Survey.
2015
<b><i>Objective:</i></b> To identify clinical parameters influencing German urologists treating cT1a renal tumours, we performed a nationwide survey among members of the German urological associations (DGU and BDU). <b><i>Material and Methods:</i></b> In spring 2012, DGU and BDU members were invited to complete our survey. For 8 cases and 3 index patients, participants were asked about their preferred treatment. Multivariate analyses were used to identify significant parameters leading the responders to favour radical nephrectomy (RN) over nephron sparing surgery (NSS) as well as active surveillance (AS) over invasive treatment. <b><i…
Parathyroid hormone is inversely related to endothelin-1 in patients on haemodialysis
2008
SUMMARY: Aim: Parathyroid hormone secretion is mainly influenced by hypocalcaemia, hyperphosphataemia and vitamin D deficiency. However, previous in vitro and in vivo studies showed that endothelin-1 can influence parathyroid hormone secretion. This study was aimed at evaluating this relationship in vivo in uraemic patients. Methods: Parathyroid hormone and endothelin-1 plasma concentrations were measured in 67 haemodialysed patients. Patients with history of cardiovascular diseases and those with parathyroid adenoma were excluded. Results: Plasma levels of endothelin-1 were found to be inversely related to those of parathyroid hormone (P < 0.04) The multiple regression analysis, carried ou…
Colony-Stimulating Factor-1
2015
A noninvasive means to predict the onset and recurrence of lupus nephritis (LN) before overt renal injury is needed to optimize and individualize treatment. Colony-stimulating factor-1 (CSF-1) is expressed by kidney tubules at the onset of LN, increases with disease progression, and spills into the circulation in lupus-prone mice. We tested the hypothesis that amplified expression of CSF-1 detected in the serum or urine correlates with intrarenal CSF-1 expression and histopathology (increased macrophage accumulation, activity indices) and clinical kidney disease activity and predicts the onset and recurrence of nephritis in patients with systemic lupus erythematosus (SLE). We found increase…
