Methods: In this prospectively designed ancillary study of the PICXEL trial, the effects of first-line combination perindopril/indapamide on ambulatory BP were compared with those of monotherapy with enalapril in 127 patients. Hypertensive patients with LVH received once daily either perindopril 2 mg/indapamide 0.625 mg (n = 65) or enalapril 10 mg (n = 62) for 52 weeks. Dose adjustments were allowed for uncontrolled BP. Twenty-four-hour ambulatory BP and echocardiographic parameters were measured at baseline, week 24, and week 52. Results: At study end, both treatments significantly improved ambulatory BP compared with baseline (p ≤ 0.01). Perindopril/indapamide treatment reduced 24-hour and daytime systolic BP (SBP) and pulse pressure (PP) significantly more than enalapril treatment (p < 0.01). No significant between-group differences were noted for diastolic BP (DBP) or for night-time measurements. Trough/peak ratios were higher with perindopril/indapamide than with enalapril (88.5 vs 65.8 for SBP and 86.7 vs 63.9 for DBP, respectively). The global smoothness index was higher with perindopril/indapamide than with enalapril (6.6 vs 5.2 for SBP and 5.6 vs 4.9 for DBP, respectively). With perindopril/indapamide treatment, LVM index was significantly reduced (−9.1 g/m2 from baseline; p vs baseline <0.001). More patients required dose increases with enalapril (87%) than with perindopril/indapamide (71%). No unusual safety elements were noted.Conclusions: First-line perindopril/indapamide combination decreased ambulatory SBP and PP, and LVM more effectively than enalapril.Keywords: left ventricular hypertrophy, ambulatory blood pressure monitoring, perindopril, indapamide, enalapri
A Systematic Approach For Kinematic Design Of Upper Limb Rehabilitation Exoskeletons
Kinematic structure of an exoskeleton is the most fundamental block of its
design and is determinant of many functional capabilities of it. Although
numerous upper limb rehabilitation devices have been designed in the recent
years, there is not a framework that can systematically guide the kinematic
design procedure. Additionally, diversity of currently available devices and
the many minute details incorporated to address certain design requirements
hinders pinpointing the core kinematics of the available devices to compare
them against each other. This makes the review of literature for identifying
drawbacks of the state of the art systems a challenging and puzzling task. In
fact, lack of a unifying framework makes designing rehabilitation devices an
intuitive process and prone to biases from currently available designs. This
research work proposes a systematic approach for kinematic design of upper limb
rehabilitation exoskeletons based on conceptual design techniques. Having
defined a solution neutral problem statement based on the characteristics of an
ideal device, the main functionality of the system is divided into smaller
functional units via the Functional Decomposition Method. Various directions
for concept generation are explored and finally, it has been shown that a vast
majority of the current exoskeleton designs fit within the proposed design
framework and the defined functionalities

Efficacy of very low dose perindopril 2 mg/indapamide 0.625 mg combination on left ventricular hypertrophy in hypertensive patients: The P.I.C.X.E.L. Study rationale and design
The PICXEL study is designed to evaluate the effects of long-term administration of very low-dose combination perindopril 2 mg/indapamide 0.625 mg (Per/Ind) vs enalapril in reducing left ventricular hypertrophy (LVH) in hypertensive patients. This multicentre, controlled, randomised, double-blind, parallel group study is carried-out to assess the variation of left ventricular mass index (LVMI) after treatment, using a centralised control of M-mode echocardiography determinations, and a dedicated software for semi-automatic measurement. Following a 4-week placebo run-in period, hypertensive outpatients aged ≥18 years, with LVH (LVMI >120 and 100 g/m2 for men and women, respectively), are randomised to receive once daily, over 52 weeks, either Per/Ind or enalapril. According to blood pressure levels, the dose may be adjusted. In addition to clinical examinations, ECG, blood pressure, heart rate and laboratory assessments echocardiographic determinations are performed for selection, at baseline, after 24 weeks and at the end of the study. The main outcome criteria is the change from baseline in LVMI which is considered the primary efficacy criterion; changes in blood pressure and echo-Doppler parameters constitute secondary criteria. Two-sided Student's t-test for independent samples will be used to differentiate the effects of the treatment between groups with α = 5%, and the inter-group difference of LVMI variation will be analysed with a power of 90%. A sample size of 500 patients is required making it necessary to randomise at least 550 patients, based on a 10% proportion of potentially non-assessable patients. The results of this study, obtained after applying strict methodological procedures and requirements, are expected to provide valuable and reliable information on the effects of long-term administration of Per/Ind on LVH, and on its potential superiority over enalapril.SCOPUS: ar.jinfo:eu-repo/semantics/publishe
