Purpose: To use laser speckle flowgraphy (LSFG) to assess blood flow (BF) in the optic nerve head (ONH) tissue and choroid during elevated intraocular pressure (IOP). Methods: This prospective study included 20 eyes of 20 healthy volunteers. The testing protocol had a baseline phase, two elevated IOP phases (+10 and +20 mm Hg), and a recovery phase. IOP was elevated by pushing against the eyelid with a novel tubular device attached to the LSFG apparatus. Measurement parameters in each phase included: LSFG-derived mean blur rate (MBR) and flow acceleration index (FAI); systemic parameters, and IOP...

Reducing body weight has been shown to lower blood pressure in obesity-related hypertension. However, success of those lifestyle interventions is limited due to poor long-term compliance. Emerging evidence indicate that feeding schedule plays a role on the regulation of blood pressure. With two studies, we examined the role of feeding schedule on energy homeostasis and blood pressure. In Study 1, rats were fed a high fat diet (HFD) ad libitum for 24 hours (Control) or for 12 hours during the dark phase (time-restricted feeding; TRF)...

Exposure to extreme-hyperbaric oxygen (HBO2), > 5-6 atmospheres absolute (ATA), produces baroreflex impairment, sympathetic hyperactivation, hypertension, tachycardia, and cerebral hyperemia, known as Phase II, culminating in seizures. We hypothesized that attenuation of the effects of high sympathetic outflow would preserve regional cerebral blood flow (rCBF) and protect against HBO2-induced seizures. To explore this possibility, we tested four adrenoceptor antagonists in conscious and anesthetized rats exposed to HBO2 at 5 and 6 ATA, respectively: phentolamine (nonselective α1 and 2), prazosin (selective α1), propranolol (nonselective β1 and 2) and atenolol (selective β1)...

BACKGROUND: Stroke is an important cause of death and disability worldwide. Since high blood pressure is an important risk factor for stroke and stroke recurrence, drugs that lower blood pressure might play an important role in secondary stroke prevention. OBJECTIVES: To investigate whether blood pressure-lowering drugs (BPLDs) started at least 48 hours after the index event are effective for the prevention of recurrent stroke, major vascular events, and dementia in people with stroke or transient ischaemic attack (TIA)...

J David Spence
Resistant hypertension (failure to achieve target blood pressures with three or more antihypertensive drugs including a diuretic) is an important and preventable cause of stroke. Hypertension is highly prevalent in China (>60% of persons above age 65), and only ~6% of hypertensives in China are controlled to target levels. Most strokes occur among persons with resistant hypertension; approximately half of strokes could be prevented by blood pressure control. Reasons for uncontrolled hypertension include (1) non-compliance; (2) consumption of substances that aggravated hypertension, such as excess salt, alcohol, licorice, decongestants and oral contraceptives; (3) therapeutic inertia (failure to intensify therapy when target blood pressures are not achieved); and (4) diagnostic inertia (failure to investigate the cause of resistant hypertension)...

PURPOSE: Arterial stiffness is an inevitable consequence of the aging process and is considered an early stage in the development of cardiovascular diseases. The perivascular adipose tissue (PVAT) is a distinct functional integral layer of the vasculature actively involved in blood pressure regulation and atherosclerosis development via PVAT-derived paracrine/autocrine factors. However, there is little knowledge regarding the relationship between PVAT and arterial stiffness. METHODS: Using unique mice lacking PVAT, high-fat diet-induced obesity, and in mice overexpressing brown adipocyte selective mitoNEET, we investigated the relationship between PVAT and arterial stiffness in mice...

PURPOSE: This study was aimed to determine whether structured written and verbal education provided to patients by community pharmacists about high blood pressure (BP) and its treatment would be (a) better retained and (b) be associated with improved BP control as compared to patients receiving verbal advice only. METHODS: The study was designed as a randomised controlled trial and was conducted in the West Midlands, UK, between January 2014 and June 2014. The primary outcome measures were differences in systolic and diastolic BP from baseline and retention of information about high BP assessed with a questionnaire at 2-, 4- and 26-week follow-up points...

INTRODUCTION: Metabolic syndrome (MetS) is a world-wide epidemic disease with an increased risk of morbidity and mortality. Treatment strategies of MetS include pharmacologic and non-pharmacologic interventions and in this respect a relevant role has been shown for nutraceutical compounds (NCs). The aim of this study was to investigate the efficacy and safety of NCs incorporated with diet and lifestyle management versus diet alone, in lowering blood pressure (BP) values and improving lipid and glucose profile, in a group of hypertensives and hyper-cholesterolemic patients with MetS...

AIM: This study aims to investigate the effect of human umbilical cord mesenchymal stem cell exosomes (hucMSC-Ex) on placental tissue and angiogenesis in rats with preeclampsia (PE). METHOD: The expression of MSC surface markers were identified by flow cytometry. Alizarin red staining and oil red O staining were used to examine osteogenic and adipogenic differentiation of hucMSCs. Western blotting was used to determine expressions of CD63 and CD81 in hucMSC-Ex. PE rat models were established using endothelial nitric oxide synthase, eNOS)NG -Nitro-l-arginine Methyl Ester, which were then treated with exosome (Exo) of low dosage (L-Exo), Exo of medium dosage (M-Exo) and Exo of high dosage (H-Exo)...

OBJECTIVES: Previous studies have suggested that hypertension in HIV-positive individuals is associated primarily with traditional risk factors such as older age, diabetes and dyslipidaemia. However, controversy remains as to whether exposure to antiretroviral (ARV) drugs poses additional risk, and we investigated this question in the Data Collection on Adverse Events of Anti-HIV Drugs (D:A:D) cohort. METHODS: The incidence of hypertension [systolic blood pressure (BP) > 140 and/or diastolic BP > 90 mmHg and/or initiation of antihypertensive treatment] was determined overall and in strata defined by demographic, metabolic and HIV-related factors, including cumulative exposure to each individual ARV drug...

BACKGROUND: Evidence on the health effects of total polyunsaturated fatty acids (PUFA) is equivocal. Fish oils are rich in omega-3 PUFA and plant oils in omega-6 PUFA. Evidence suggests that increasing PUFA-rich foods, supplements or supplemented foods can reduce serum cholesterol, but may increase body weight, so overall cardiovascular effects are unclear. OBJECTIVES: To assess effects of increasing total PUFA intake on cardiovascular disease and all-cause mortality, lipids and adiposity in adults...
