MECHANISMS OF HYPNOTIC ANALGESIA EXPLAINED BY FUNCTIONAL MAGNETIC RESONANCE (fMRI).

Hypnotic-focused analgesia (HFA) was produced in 20 highly hypnotizable subjects receiving nociceptive stimulations while undergoing functional magnetic resonance imaging (fMRI). The fMRI pattern in brain cortex activation while receiving a painful stimulus was recorded both during nonhypnosis and during HFA. The scanning protocol included the acquisition of a T1-weighted structural scan, 4 functional scans, a T2-weighted axial scan, and a fluid attenuated inversion recovery (FLAIR) scan.

Caffeine intake reduces incident atrial fibrillation at a population level.

Background The general belief is that caffeine increases the risk of hyperkinetic arrhythmias, including atrial fibrillation. The aim of this study is to investigate the effect of chronic caffeine intake on incident atrial fibrillation in general population. Design and methods A population cohort of 1475 unselected men and women observed for 12 years and left free to intake food or beverages containing caffeine was studied.

Caffeine intake and abstract reasoning among 1374 unselected men and women from general population. Role of the -163C>A polymorphism of CYP1A2 gene.

Background And Aims: The possible effect of caffeine as an enhancer of cognitive performance, particularly that on abstract reasoning, has never been studied in an epidemiological setting, especially in relation to -163C>A polymorphism of CYP1A2 gene, largely controlling caffeine metabolism. Aim of this study was to ascertain whether in general population free chronic caffeine intake modifies abstract reasoning, and if this effect is influenced by the above mentioned genotype, by age, schooling, ethanol intake and smoking habits.

Methods: We studied 1374 unselected men and women aged 51 ± 15 years (range 18-89) from a general population.

Validation of the A&D UM-211 device for office blood pressure measurement according to the European Society of Hypertension International Protocol revision 2010.

The aim of this study was to define the accuracy of UM-211, an automated oscillometric device for office use coupled to several cuffs for different arm sizes, according to the International Protocol of the European Society of Hypertension. The validation was performed in 33 individuals. Their mean age was 59.

Validation of the A&D UM-201 device for office blood pressure measurement according to the European Society of Hypertension International Protocol Revision 2010.

The aim of this study was to determine the accuracy of the A&D UM-201 device coupled to several cuffs for different arm sizes for office blood pressure (BP) measurement according to the International Protocol of the European Society of Hypertension. Evaluation was carried out in 33 individuals. The mean age of the individuals was 59.

Poor Reliability of Wrist Blood Pressure Self-Measurement at Home: A Population-Based Study.

The reliability of blood pressure measurement with wrist devices, which has not previously been assessed under real-life circumstances in general population, is dependent on correct positioning of the wrist device at heart level. We determined whether an error was present when blood pressure was self-measured at the wrist in 721 unselected subjects from the general population. After training, blood pressure was measured in the office and self-measured at home with an upper-arm device (the UA-767 Plus) and a wrist device (the UB-542, not provided with a position sensor).
