<h2>Summary</h2><h3>Background</h3> Studies evaluating titration of antihypertensive medication using self-monitoring give contradictory findings and the precise place telemonitoring over alone is unclear. The TASMINH4 trial aimed to assess efficacy self-monitored blood pressure, with or without telemonitoring, for in primary care, compared usual care. <h3>Methods</h3> This study was a parallel randomised controlled done 142 general practices UK, included hypertensive patients older than 35...

In the PATHWAY-2 study of resistant hypertension, spironolactone reduced blood pressure substantially more than conventional antihypertensive drugs. We did three substudies to assess mechanisms underlying this superiority and pathogenesis hypertension.PATHWAY-2 was a randomised, double-blind crossover trial done at 14 UK primary secondary care sites in 314 patients with hypertension. Patients were given 12 weeks once daily treatment each placebo, 25-50 mg, bisoprolol 5-10 doxazosin 4-8 mg...

To determine whether, in normal pregnancies, there is evidence of oxidative stress that related to the lipid changes observed pregnancy.Longitudinal study healthy women having a pregnancy. Samples were obtained towards end each trimester and after 8 weeks postpartum.Seventeen during singleton pregnancy compared with 12 healthy, non-pregnant women.Oxidative was determined by measuring total antioxidant capacity (TAC), uric acid hydroperoxides (LHP).

The visceral afferent feedback hypothesis proposes that sensorimotor function is impaired by cortical inhibition associated with increased baroreceptor activation. This study the first to examine effects of naturally occurring variations in activity across cardiac cycle on cutaneous sensory detection thresholds. In each trial, an electrocutaneous stimulus was delivered index finger at one three intervals (0, 300, 600 ms) after R-wave electrocardiogram. Separate interleaving up-down...

Introduction Wolfram syndrome ( WFS1- Spectrum Disorder) is an ultra-rare monogenic form of progressive neurodegeneration and diabetes mellitus. In common with most rare diseases, there are no therapies to slow or stop disease progression. Sodium valproate, anticonvulsant neuroprotective properties, anticipated mediate its effect via alteration cell cycle kinetics, increases in p21 cip1 expression levels reduction apoptosis increase Wolframin protein expression. To date, have been...

A baroreflex mechanism may explain hypertensive hypoalgesia. At rest, arterial baroreceptors are stimulated during the systolic upstroke of pressure pulse wave. This study examined effects naturally occurring variations in baroreceptor activity cardiac cycle on an objective measure pain, nociceptive flexion reflex (NFR). Two interleaved up–down staircase procedures determined separate NFR thresholds systole and diastole 36 healthy, normotensive young adults. On odd‐numbered trials, sural...

Patients often have lower (white coat effect) or higher (masked ambulatory/home blood pressure readings compared with clinic measurements, resulting in misdiagnosis of hypertension. The present study assessed whether and patient characteristics from a single visit can accurately predict the difference between (the home-clinic difference).

Nonadherence to medication is present in at least 50% of patients with apparent treatment-resistant hypertension. We examined the factors associated nonadherence as detected by a liquid chromatography-tandem mass spectrometry (LC-MS/MS)-based urine antihypertensive drug assay.All test results, carried out for uncontrolled hypertension (BP persistently >140/90 mmHg) between January 2015 and December 2016 single toxicology laboratory were analysed. Drugs compared drugs prescribed. Patients...

Abstract The arterial baroreflex may mediate hypertensive hypoalgesia. Carotid baroreceptors can be artificially stimulated by neck suction and inhibited compression. Effects of brief compression on nociceptive responding pain were studied in 25 normotensive adults. sural nerve was electrocutaneously at threshold intensity during systole or diastole combined with suction, compression, no pressure. Nociceptive indexed electromyographic activity elicited the biceps femoris. Participants rated...
