TL;DR: These 4 hypothetical cases highlight some of the new features in the 2018 American Heart Association/American College of Cardiology multisociety cholesterol management guidelines, and a multiple-choice format is used to engage clinicians in selecting the best choice.
Abstract: These 4 hypothetical cases highlight some of the new features in the 2018 American Heart Association/American College of Cardiology multisociety cholesterol management guidelines. Topics include management issues in a secondary prevention patient judged to be at very high risk of another event, a patient with familial hypercholesterolemia with a low-density lipoprotein cholesterol level of 190 mg/dL or greater (to convert to millimoles per liter, multiply by 0.0259), a primary prevention patient with intermediate (7.5%-19.9%) 10-year atherosclerotic cardiovascular risk, and a patient who has statin-associated adverse effects. A multiple-choice format is used to engage clinicians in selecting the best choice based on guidance from the new 2018 cholesterol management guidelines.

TL;DR: A significant portion of patients with moderate hypercholesterolaemia have an abnormal LDL species, which is not the 3500 mutation, but delays clearance of LDL from the circulation, suggesting that two forms of LDL might be separable by ultracentrifugation.
Abstract: Recent studies have shown that one cause of primary moderate hypercholesterolaemia is familial defective apolipoprotein B-100 (FDB), a condition in which a mutation in apolipoprotein B-100 (apo B-100) causes low-density lipoproteins (LDL) to bind poorly to LDL receptors. One specific mutation, a glutamine-for-arginine transformation at position 3500 of apo B-100, has been reported to produce FDB. However, other mutations in apo B-100 might also cause FDB. The present study was designed to determine whether some patients with hypercholesterolaemia, who do not have the 3500 defect, may have a slowly cleared subfraction of LDL compatible with other forms of FDB. It was postulated that slowly removed LDL should accumulate excess cholesterol ester and hence be less dense than normal LDL. If so, in patients who are heterozygous for FDB, two forms of LDL might be separable by ultracentrifugation. To test this hypothesis, less-dense (d = 1.030 g ml-1) and more-dense (d = 1.040 g ml-1) subfractions of LDL were isolated from a patient with proven FDB (3500 mutation); the two forms of LDL were labelled with different isotopes of radioiodine and re-injected into the patient. The less-dense form was removed much more slowly (0.285 pools day-1) than more-dense LDL (0.570 pools day-1). This finding appeared to confirm the validity of the approach. The same procedure was then applied to 18 other patients having elevated LDL cholesterol but not the 3500 mutation. In 13 patients, the two forms of LDL were removed at essentially identical rates, suggesting that they did not have an abnormal form of LDL. In the other five, less-dense LDL were removed at a significantly slower rate than more-dense LDL; this finding suggests that a significant portion of patients with moderate hypercholesterolaemia have an abnormal LDL species, which is not the 3500 mutation, but delays clearance of LDL from the circulation.

01 Apr 2017TL;DR: In this study, adiposity‐associated cancer risk was heterogeneous and varied by fat depot: VAT was not independently associated with incident cancer, and LBF seemed to protect against cancer development.
Abstract: Objective To examine the association between specific adipose tissue depots and the risk of incident cancer in the Dallas Heart Study. Patients and Methods Individuals without prevalent cancer in the Dallas Heart Study underwent quantification of adipose depots: visceral adipose tissue (VAT), abdominal subcutaneous adipose tissue, and liver fat by magnetic resonance imaging, and subcutaneous lower-body fat (LBF) by dual-energy X-ray absorptiometry from January 1, 2000, through December 31, 2002, and were observed for the development of cancer for up to 12 years. Multivariable Cox proportional hazards modeling was performed to examine the association between fat depots and cancer. Results Of 2627 participants (median age, 43 years; 69% nonwhite race), 167 (6.4%) developed cancer. The most common primary sites of cancer were the breast (in women) and the prostate (in men). In multivariable models adjusted for age, sex, race, smoking, alcohol use, family history of malignancy, and body mass index, a 1-SD increase in VAT was not associated with increased risk of cancer (hazard ratio [HR], 0.94; 95% CI, 0.77-1.14). In contrast, each 1-SD increase in LBF was associated with a reduced incidence of cancer (HR, 0.69; 95% CI, 0.52-0.92) in the fully adjusted model. Conclusions In this study, adiposity-associated cancer risk was heterogeneous and varied by fat depot: VAT was not independently associated with incident cancer, and LBF seemed to protect against cancer development. Further studies of the adiposity-cancer relationship, including serial assessments, are needed to better elucidate this relationship.

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.
