Micro-albuminuria in obese subjects: relationship among body fat distribution, blood pressure and left ventricular structure and function.
1998
OBJECTIVE: To evaluate the relationships among micro-albuminuria, blood pressure and measurements of left ventricular structure and function in centrally and peripherally obese subjects compared with members of a lean control group. METHODS: Centrally obese subjects were subdivided according to whether they had levels of micro-albuminuria higher than 30 mg/24 h (micro-albuminuric group) or lower than or equal to 30 mg/24 h (normo-albuminuric group). For all the subjects we measured heart rate, casual mean blood pressure (MBP), 24 h MBP, total cholesterol level, high-density lipoprotein cholesterol, lipoprotein (a) level, fasting immunoreactive insulin level, plasma renin activity, plasma al…
Obesità e rischio cardiovascolare.
2007
L’obesità rappresenta attualmente la più diffusa patologia da malnutrizione delle Società occidentali industrializzate e si associa spesso a svariate complicanze invalidanti sia mediche che chirurgiche. Essa è, inoltre, una condizione ad elevata prevalenza ed in continuo e costante incremento, al punto da essere etichettata come una “Epidemia globale”. Nella presente review sono stati analizzati i risultati degli studi più recenti che hanno individuato nella patologia del tessuto adiposo uno dei meccanismi più importanti nello sviluppo dell’aterosclerosi e delle manifestazioni cliniche ad essa connesse. Particolare riguardo è stato dato, oltre che alle evidenze epidemiologiche riguardanti i…
Within-patient reproducibility of the aldosterone: renin ratio in primary aldosteronism.
2010
The plasma aldosterone concentration:renin ratio (ARR) is widely used for the screening of primary aldosteronism, but its reproducibility is unknown. We, therefore, investigated the within-patient reproducibility of the ARR in a prospective multicenter study of consecutive hypertensive patients referred to specialized centers for hypertension in Italy. After the patients were carefully prepared from the pharmacological standpoint, the ARR was determined at baseline in 1136 patients and repeated after, on average, 4 weeks in the patients who had initially an ARR > or =40 and in 1 of every 4 of those with an ARR <40. The reproducibility of the ARR was assessed with Passing and Bablok and Demi…

Effects of acute CPAP application on baroreflex control of heart rate during sleep in severe obstructive sleep apnea.
2006
Baroreflex control of heart rate during sleep (baroreflex sensitivity; BRS) has been shown to be depressed in obstructive sleep apnoea (OSA), and improved after treatment with continuous positive airway pressure (CPAP). Whether CPAP also acutely affects BRS during sleep in uncomplicated severe OSA is still debatable. Blood pressure was monitored during nocturnal polysomnography in 18 patients at baseline and during first-time CPAP application. Spontaneous BRS was analysed by the sequence method, and estimated as the mean sequence slope. CPAP did not acutely affect mean blood pressure or heart rate but decreased cardiovascular variability during sleep. Mean BRS increased slightly during CPAP…
Effects of rowing training on airway responsiveness in asthmatics
2012
We previously reported that after a short course of rowing training the responsiveness to methacholine (Mch) in the absence of deep inspiration (DI) decreased in healthy subjects. We assessed whether a similar beneficial effect of exercise on airway responsiveness could occur in asthmatics. Nine patients (M/F: 3/6; mean age±SD: 24±2 yrs) with mild untreated asthma (FEV(1): 100±7.4% pred, FEV(1)/VC 90±6.5%) underwent a series of single dose Mch bronchoprovocations in the absence of DI in the course of a indoor rowing training consisted of two to three sessions per week for 10 weeks (total 28 sessions). Each session included a warm-up period for 20 min (running and stretching), and a specific…
