Outcome of esophageal function and 24-hour esophageal pH monitoring after vertical banded gastroplasty and Roux-en-Y gastric bypass.
2004
Background: One of the co-morbidities frequently associated with morbid obesity is gastro-esophageal reflux disease (GERD), present in >50 % of morbidly obese individuals. We compared the anti-reflux effect of vertical banded gastroplasty (VBG) and Roux-en-Y gastric bypass (RYGBP), and their effect on esophageal function. Methods: 10 patients underwent VBG and 40 patients underwent RYGBP. Anthropometric parameters, symptomatology of GERD, esophageal manometry (EM), isotopic esophageal emptying (IEE) and 24hr esophageal pH monitoring were recorded in all patients preoperatively, and at 3 months and 1 year postoperatively. Results: Preoperatively, there was a high prevalence of GERD, symptoma…
Sociocognitive factors associated with nonadherence to medication after hospital discharge
2010
Poor adherence to prescribed medication is a well-known problem and continues to be a major challenge in all medical specialties. Unlike previous studies that have mainly focused on nonadherence behaviors in specific diseases, this study sought to examine socio-cognitive factors associated with nonadherence behavior in a sample of a general clinical population. A questionnaire investigating socio-demographic and cognitive factors and a telephone follow-up interview were administered to 84 patients recruited in a General Medicine Unit before their discharge. Half of the participants were informed about that follow-up procedure. One month after hospital discharge, 42% of uninformed patients r…
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…
Heart rate-running speed index may be an efficient method of monitoring endurance training adaptation.
2014
The aim of this study was to investigate whether a novel heart rate (HR)-running speed index could be used in monitoring adaptation to endurance training. Forty-five recreational runners underwent a 2-phased 28-week training regime. The first 14 weeks included basic endurance training, whereas the second 14 weeks were more intensive (increased volume and intensity). A maximal treadmill running test was performed in the beginning of the experiment, in the middle of basic endurance training, and at the end of each training period (PRE, WEEK 7, WEEK 14, and POST). The novel HR-running speed index was calculated from every continuous-type running exercise during the 28-week experiment based on …
Twenty-Four Hour Ambulatory Blood Pressure Monitoring to Evaluate Effects on Blood Pressure of Physical Activity in Hypertensive Patients
2006
OBJECTIVE: Elevated blood pressure is an important risk factor for cardiovascular disease and stroke. Several studies have demonstrated that physical exercise reduces blood pressure levels in hypertensive subjects and improves control of several well-known risk factors for atherosclerosis such as diabetes mellitus, blood lipid profile and obesity. Our group attempted to evaluate if an exercise program based on periodic controlled fast walking sessions would reduce blood pressure levels in hypertensive subjects. DESIGN: We enrolled hypertensive subjects not suffering from obesity (Body Mass Index <30) already under pharmacological therapy; in these subjects we performed a six-week program of…
Daily steps among Finnish adults: Variation by age, sex, and socioeconomic position
2011
Aims: The aim of this study was to provide descriptive population-based pedometer data from adults aged 30-45 years in Finland, and to compare daily step counts with evidence-based indices. Methods: The data was collected from 1853 participants in 7 consecutive days in winter 2007—08 in part of 27-year follow up of the Cardiovascular Risk in Young Finns study. Results: The participants took (mean±standard deviation) 7499 ± 2908 steps/day. Step counts included 1925 ± 2052 aerobic steps/day gathered in bouts of at least 10 min continuous ambulatory activity. Women had more total steps than men ((7824 ± 2925 vs. 7089 ± 2774; p < 0.001). Although participants had higher mean total steps on …
Disrupting the right pars opercularis with electrical stimulation frees the song: case report
2015
International audience; The authors report the first case of a strikingly unusual speech impairment evoked by intraoperative electrostimulation in a 36-year-old right-handed patient, a well-trained singer, who underwent awake surgery for a right fronto-temporoinsular low-grade glioma. Functionally disrupting the pars opercularis of the right inferior frontal gyrus led the patient to automatically switch from a speaking to a singing mode of language production. Given the central role of the right pars opercularis in the inhibitory control network, the authors propose that this finding may be interpreted as possible evidence for a competitive and independent neurocognitive subnetwork devoted …
Measurement of Cortical Microcirculation During Intracranial Aneurysm Surgery by Combined Laser-Doppler Flowmetry and Photospectrometry
2011
Accidental vessel occlusion is one major risk of intracranial aneurysm surgery potentially causing cerebral ischemia. The intraoperative assessment of cerebral ischemia remains a technological challenge.As a novel approach, cortical tissue integrity was monitored using simultaneous measurements of regional capillary-venous cerebral blood flow (rvCBF), oxygen saturation (Srvo2), and hemoglobin amount (rvHb) during aneurysm surgery.Fifteen patients scheduled for aneurysm surgery of the anterior and posterior circulation were included. A fiber optic probe was placed on the cortex associated with the distal branch of the aneurysmatic vessel. Blinded measurements by combined laser-Doppler flowme…
Associations between intracranial pressure, intraocular pressure and mean arterial pressure in patients with traumatic and non-traumatic brain injuri…
2008
Introduction: Anatomical proximity of the eye and the intracranial space is a fact but the existence of physiological and pathophysiological relationships between them is elusive. The objective of this study was to explore anatomical and pathophysiological interactions between the eye and the intracranial space and to assess clinical utility of intraocular pressure measurement in estimation of intracranial pressure in patients with brain injuries and to discover how haemodynamic instability could influence these interactions. Controversy surrounds the recent literature concerning this problem and the consensus has not been achieved. Materials and methods: We evaluated the correlation betwee…
Comparison of tumour necrosis factor and endothelin-1 between essential and renal hypertensive patients
1998
The present study was performed to compare circulating levels of tumour necrosis factor-alpha (TNFalpha) and plasma endothelin 1 (ET-1), of hypertensive patients with or without renal failure and with those of normotensive healthy subjects. The study population consisted of 21 healthy normotensive subjects and 22 hypertensive patients, 11 with essential hypertension, and 11 with hypertension and chronic renal failure (CRF). Plasma ET-1 levels, serum TNFalpha and creatinine, creatinine clearance, 24-h urinary albumin excretion (UAE) were assayed, and 24-h blood pressure monitoring was obtained in all subjects. Office blood pressure was similar between hypertensive patients with and without C…
