Sequential measurement of the neurosensory retina in hypertensive disorders of pregnancy: a model of microvascular injury in hypertensive emergency.

Optical coherence tomography of the eye suggests the retina thins in normal pregnancy. Our objectives were to confirm and extend these observations to women with hypertensive disorders of pregnancy (HDP). Maternal demographics, clinical/laboratory findings and measurements of macular thickness were repeatedly collected at gestational ages <20 weeks, 20-weeks to delivery, at delivery and postpartum.

Scalable synthesis of [8]cycloparaphenyleneacetylene carbon nanohoop using alkyne metathesis.

Large scale synthesis of cycloparaphenyleneacetylenes has been challenging due to low macrocyclization yields and harsh aromatization methods that often decompose strained alkynes. Herein, a -stilbene-based building block is subjected to alkyne metathesis macrocylization. The following sequence of alkene-selective bromination and dehydrobromination afforded a [8]cycloparaphenyleneacetylene derivative in high yield with good scalability.

Functional-Optical Coherence Tomography: A Non-invasive Approach to Assess the Sympathetic Nervous System and Intrinsic Vascular Regulation.

Sympathetic nervous system dysregulation and vascular impairment in neuronal tissue beds are hallmarks of prominent cardiorespiratory diseases. However, an accurate and convenient method of assessing SNA and local vascular regulation is lacking, hindering routine clinical and research assessments. To address this, we investigated whether spectral domain optical coherence tomography (OCT), that allows investigation of retina and choroid vascular responsiveness, reflects sympathetic activity in order to develop a quick, easy and non-invasive sympathetic index.

Renal denervation therapy for the treatment of resistant hypertension: a position statement by the Canadian Hypertension Education Program.

Renal denervation is a novel catheter-based, percutaneous procedure using radiofrequency energy to ablate nerves within the renal arteries. This procedure might help to significantly lower blood pressure (BP) in patients with resistant hypertension, defined as BP > 140/90 mm Hg (> 130/80 mm Hg for those with diabetes) despite use of ≥ 3 optimally dosed antihypertensive agents, ideally including 1 diuretic agent. The Canadian Hypertension Education Program Recommendations Task Force reviewed the current evidence on safety and efficacy of this procedure.

We updated the evidence-based recommendations for the diagnosis, assessment, prevention, and treatment of hypertension in adults for 2013. This year's update includes 2 new recommendations. First, among nonhypertensive or stage 1 hypertensive individuals, the use of resistance or weight training exercise does not adversely influence blood pressure (BP) (Grade D).

The 2012 Canadian hypertension education program recommendations for the management of hypertension: blood pressure measurement, diagnosis, assessment of risk, and therapy.

We updated the evidence-based recommendations for the diagnosis, assessment, prevention, and treatment of hypertension in adults for 2012. The new recommendations are: (1) use of home blood pressure monitoring to confirm a diagnosis of white coat syndrome; (2) mineralocorticoid receptor antagonists may be used in selected patients with hypertension and systolic heart failure; (3) a history of atrial fibrillation in patients with hypertension should not be a factor in deciding to prescribe an angiotensin-receptor blocker for the treatment of hypertension; and (4) the blood pressure target for patients with nondiabetic chronic kidney disease has now been changed to < 140/90 mm Hg from < 130/80 mm Hg. We also reviewed the recent evidence on blood pressure targets for patients with hypertension and diabetes and continue to recommend a blood pressure target of less than 130/80 mm Hg.
