TL;DR: These findings are consistent with the hypothesis that decreased activity of noradrenergic depressor neurons in the anterior hypothalamus mediate and increase in blood pressure that occurs in NaCI-sensitine animals during dietary NaCl supplementation by releasing tonic inhibition of sympathetic outflow.
Abstract: Summary: Sensitivity to the pressor effect, of dietary NaCI and the depressor effect, of dietary Ca is inherited. High NaCl diets accelerate the development and or exacerbate the severity of hypertension in NaCl-sensitive substrains of spontaneously hypertensive rat (SHR-S) but not in NaCl-resistant substrains of SHR (SHR-R) or in normotensive Wistar-Kyoto (WKY) control rats. High NaCl intake leads to increased circulating noradenaline levels and increased depressor responses to ganglionie blockade in SHR-S but not in SHR-R or WKY rats, indicating that peripheral sympathetic nervous system activity and neurogenic peripheral vascular tone are increased by NaCl supplementation in SHR-S. but not in SHR-R or WKY rats. Further. dietary NaCl loading in SHR-S decreases endogenous noradrenaline stores and noradrenaline release in the anterior hypothalamus, a brain region that contains neurons that give rise to depressor responses when stimulated chemically or electrically. These findings are consistent with the hypothesis that decreased activity of noradrenergic depressor neurons in the anterior hypothalamus mediate and increase in blood pressure that occurs in NaCI-sensitine animals during dietary NaCl supplementation by releasing tonic inhibition of sympathetic outflow. The exacerbation of hypertension and changes in central noradrenergic activity are observed only in NaCl-loaded SHR-S. not in SHR-R or WKY rats. indicating that these NaCl-induced alterations in central noradrenergic activity are genetically mediated. Dietary Ca supplementation prevents for reversest the NaCl-induced changes in blood pressure. peripheral sympathetic nervous system activity, and anterior hypothalamic noradrenaline release in SHR-S. suggesting that dietary NaCI and Ca may have opposing effects on the same regulators pathway. The genetic defect in NaCl Ca2+ sensitivity of blood pressure is not yet identified. but probably involve cation transport at the cellular level.

TL;DR: In both Black and non-Black participants, triple-combination treatment resulted in significant and similar mean reductions in SeDBP and SeSBP with a greater proportion of participants reaching BP goal compared with dual- Combination treatments, regardless of race.
Abstract: Background Although awareness of hypertension in Black patients has increased, blood pressure (BP) is frequently inadequately controlled. Objective
This prespecified subgroup analysis of the TRINITY study evaluated the efficacy and safety of olmesartan medoxomil (OM) 40 mg, amlodipine besylate (AML) 10 mg, and hydrochlorothiazide (HCTZ) 25 mg triple-combination treatment compared with the component dual-combination treatments in Black and non-Black study participants. Study Design
TRINITY was a 12-week, randomized, double-blind, parallel-group evaluation. The first patient was enrolled in May 2008 and the last patient completed the study in February 2009. The study consisted of a 3-week washout period for participants receiving antihypertensive therapy and a 12-week double-blind treatment period. For the treatment phase, all study participants were stratified by age, race, and diabetes mellitus status and randomized to a treatment sequence that led to their final treatment assignment, which they received from weeks 4 to 12 (OM 40 mg/AML 10 mg/HCTZ 25 mg, OM 40 mg/AML 10 mg, OM 40 mg/HCTZ 25 mg, or AML 10 mg/HCTZ 25 mg). In the first 2 weeks of the double-blind treatment period, all participants received either dual-combination treatment or placebo. Participants assigned to dual-combination treatment continued treatment until week 4, and participants receiving placebo were switched at week 2 to receive one of the dual-combination treatments until week 4. At week 4, participants either continued dual-combination treatment or randomly received triple-combination treatment until week 12. Setting
317 clinical sites in the USA and Puerto Rico were included in the study. Patients
Study participants eligible for randomization (N = 2492) were ≥18 years of age with mean seated blood pressure (SeBP) ≥140/100 mmHg or ≥160/90 mmHg (off antihypertensive medication). Intervention
The intervention was with dual- or triple-combination antihypertensive treatment: OM 40 mg/AML 10 mg/HCTZ 25 mg, OM 40 mg/AML 10 mg, OM 40 mg/HCTZ 25 mg, or AML 10 mg/HCTZ 25 mg. Main Outcome Measure
The primary efficacy variable was the change in least squares (LS) mean seated diastolic BP (SeDBP) from baseline to week 12. Secondary efficacy variables included the LS mean change in seated systolic BP (SeSBP), percentage of study participants reaching BP goal, and safety parameters. >Results
In both Black and non-Black participants, triple-combination treatment resulted in significant and similar mean reductions in SeDBP and SeSBP (p≤0.0001 vs each dual-combination treatment) with a greater proportion of participants reaching BP goal compared with dual-combination treatments, regardless of race. Most treatment-emergent adverse events were mild or moderate in severity and no new safety concerns were identified. Conclusion
Triple-combination treatment provided greater BP reductions than dual-combination treatments regardless of race. Clinical Trial Registration
Registered at ClinicalTrials.gov as NCT00649389.

TL;DR: These analyses have clearly demonstrated that blood pressure lowering in ISH confers improved prognosis and reduced cardiovascular and renal outcomes in both diabetics and non‐diabetics.
Abstract: Age-related arterial stiffness is more pronounced in diabetics compared to non-diabetics, which could explain the prevalence of isolated systolic hypertension (ISH, systolic blood pressure > or =140 mmHg and diastolic blood pressure <90 mmHg) being approximately twice that of the general population without diabetes. Large-scale interventional outcome trials have also shown that diabetics usually have higher pulse pressure and higher systolic blood pressure than non-diabetics. Advanced glycation end-product formation has been implicated in vascular and cardiac complications of diabetes including loss of arterial elasticity, suggesting possibilities for new therapeutic options. With increasing age, there is a shift to from diastolic to systolic blood pressure and pulse pressure as predictors of cardiovascular disease. This may affect drug treatment as different antihypertensive drugs may have differential effects on arterial stiffness that can be dissociated from their effects on blood pressure. While thiazide diuretics are associated with little or no change in arterial stiffness despite a robust antihypertensive effect, angiotensin converting enzyme inhibitors, angiotensin II receptor blockers and calcium-channel blockers have been shown to reduce arterial stiffness. However, combination therapy is nearly always necessary to obtain adequate blood pressure control in diabetics. There are no randomized controlled trials looking specifically at treatment of ISH in diabetics. Recommendations regarding treatment of ISH in diabetes mellitus type 2 are based on extrapolation from studies in non-diabetics, post-hoc analyses and prespecified subgroup analysis in large-scale studies, and metaanalysis. These analyses have clearly demonstrated that blood pressure lowering in ISH confers improved prognosis and reduced cardiovascular and renal outcomes in both diabetics and non-diabetics.

TL;DR: There is, I think, something ethereal about i —the square root of minus one, which seems an odd beast at that time—an intruder hovering on the edge of reality.
Abstract: There is, I think, something ethereal about i —the square root of minus one. I remember first hearing about it at school. It seemed an odd beast at that time—an intruder hovering on the edge of reality.
Usually familiarity dulls this sense of the bizarre, but in the case of i it was the reverse: over the years the sense of its surreal nature intensified. It seemed that it was impossible to write mathematics that described the real world in …

TL;DR: The most effective therapy prescribed by the most careful clinician will control hypertension only if patients are motivated, and empathy builds trust and is a potent motivator.
Abstract: "The Seventh Report of the Joint National Committee on Prevention, Detection,
Evaluation, and Treatment of High Blood Pressure" provides a new guideline
for hypertension prevention and management. The following are the key messages(1) In persons older than 50 years, systolic blood pressure (BP) of
more than 140 mm Hg is a much more important cardiovascular disease
(CVD) risk factor than diastolic BP; (2) The risk of CVD, beginning at 115/75
mm Hg, doubles with each increment of 20/10 mm Hg; individuals who are normotensive
at 55 years of age have a 90% lifetime risk for developing hypertension; (3)
Individuals with a systolic BP of 120 to 139 mm Hg or a diastolic BP of 80
to 89 mm Hg should be considered as prehypertensive and require health-promoting
lifestyle modifications to prevent CVD; (4) Thiazide-type diuretics should
be used in drug treatment for most patients with uncomplicated hypertension,
either alone or combined with drugs from other classes. Certain high-risk
conditions are compelling indications for the initial use of other antihypertensive
drug classes (angiotensin-converting enzyme inhibitors, angiotensin-receptor
blockers, β-blockers, calcium channel blockers); (5) Most patients with
hypertension will require 2 or more antihypertensive medications to achieve
goal BP (<140/90 mm Hg, or <130/80 mm Hg for patients with diabetes
or chronic kidney disease); (6) If BP is more than 20/10 mm Hg above goal
BP, consideration should be given to initiating therapy with 2 agents, 1 of
which usually should be a thiazide-type diuretic; and (7) The most effective
therapy prescribed by the most careful clinician will control hypertension
only if patients are motivated. Motivation improves when patients have positive
experiences with and trust in the clinician. Empathy builds trust and is a
potent motivator. Finally, in presenting these guidelines, the committee recognizes
that the responsible physician's judgment remains paramount.

TL;DR: In those older than age 50, systolic blood pressure of greater than 140 mm Hg is a more important cardiovascular disease (CVD) risk factor than diastolic BP, and hypertension will be controlled only if patients are motivated to stay on their treatment plan.
Abstract: The National High Blood Pressure Education Program presents the complete Seventh Report of the Joint National Committee on Prevention, Detection, Evaluation, and Treatment of High Blood Pressure. Like its predecessors, the purpose is to provide an evidence-based approach to the prevention and management of hypertension. The key messages of this report are these: in those older than age 50, systolic blood pressure (BP) of greater than 140 mm Hg is a more important cardiovascular disease (CVD) risk factor than diastolic BP; beginning at 115/75 mm Hg, CVD risk doubles for each increment of 20/10 mm Hg; those who are normotensive at 55 years of age will have a 90% lifetime risk of developing hypertension; prehypertensive individuals (systolic BP 120-139 mm Hg or diastolic BP 80-89 mm Hg) require health-promoting lifestyle modifications to prevent the progressive rise in blood pressure and CVD; for uncomplicated hypertension, thiazide diuretic should be used in drug treatment for most, either alone or combined with drugs from other classes; this report delineates specific high-risk conditions that are compelling indications for the use of other antihypertensive drug classes (angiotensin-converting enzyme inhibitors, angiotensin-receptor blockers, beta-blockers, calcium channel blockers); two or more antihypertensive medications will be required to achieve goal BP (<140/90 mm Hg, or <130/80 mm Hg) for patients with diabetes and chronic kidney disease; for patients whose BP is more than 20 mm Hg above the systolic BP goal or more than 10 mm Hg above the diastolic BP goal, initiation of therapy using two agents, one of which usually will be a thiazide diuretic, should be considered; regardless of therapy or care, hypertension will be controlled only if patients are motivated to stay on their treatment plan. Positive experiences, trust in the clinician, and empathy improve patient motivation and satisfaction. This report serves as a guide, and the committee continues to recognize that the responsible physician's judgment remains paramount.
