Pterostilbene on metabolic parameters: a randomized, double-blind, and placebo-controlled trial.

Introduction. The purpose of this trial was to evaluate the effect of pterostilbene on metabolic parameters. Methods.

Resistant nonalcoholic fatty liver disease amelioration with rosuvastatin and pioglitazone combination therapy in a patient with metabolic syndrome.

Objective: To report a case describing resolution of persistently elevated aminotransferases in a patient with severe, resistant nonalcoholic fatty liver disease (NAFLD) using combination therapy.

Case Summary: A 47-year-old obese male patient presented with a history of elevated aminotransferases and numerous statin intolerances. In addition to worsening control of diabetes and dyslipidemia, severe NAFLD was confirmed.

Analysis of safety from a human clinical trial with pterostilbene.

Objectives. The purpose of this trial was to evaluate the safety of long-term pterostilbene administration in humans. Methodology.

Pharmacologic therapy for nonalcoholic fatty liver disease in adults.

Nonalcoholic fatty liver disease (NAFLD) is characterized by the accumulation of triglycerides in hepatocytes in the absence of excessive alcohol intake, ranging in severity from simple steatosis to nonalcoholic steatohepatitis (NASH). Nonalcoholic steatohepatitis can ultimately progress to cirrhosis and hepatocellular carcinoma. NAFLD is associated with cardiometabolic risk factors and is the most common chronic liver disease among adults in the Western Hemisphere.

Evaluation of blood pressure measurement and agreement in an academic health sciences center.

The authors assessed the process of blood pressure (BP) measurement and level of adherence to recommended procedures at representative sites throughout a large academic health sciences center. A casual observer assessed the setting and observed the process, noting the equipment, technique, and BP recorded by site personnel. A trained observer then repeated the patient's BP measurement following American Heart Association recommendations.

Hypertension in postmenopausal women.

Blood pressure is typically lower in premenopausal women than in men. However, after menopause, the prevalence of hypertension in women is higher than it is in men. Hypertension is a major risk factor for cardiovascular disease in women and men, but cardiovascular disease is the leading cause of death in women.

Effect of dietary protein supplementation on blood pressure: a randomized, controlled trial.

Background: Observational studies have reported an inverse association between dietary protein intake and blood pressure (BP). We compared the effect of soy protein, milk protein, and carbohydrate supplementation on BP among healthy adults.

Methods And Results: We conducted a randomized, double-blind crossover trial with 3 intervention phases among 352 adults with prehypertension or stage 1 hypertension in New Orleans, LA, and Jackson, MS, from September 2003 to April 2008.

Socioeconomic position is positively associated with blood pressure dipping among African-American adults: the Jackson Heart Study.

Background: Blunted nocturnal blood pressure (NBP) dipping is a significant predictor of cardiovascular events. Lower socioeconomic position (SEP) may be an important predictor of NBP dipping, especially in African Americans (AA). However, the determinants of NBP dipping are not fully understood.

Improving influenza vaccination rates by targeting individuals not seeking early seasonal vaccination.

Background: Influenza morbidity and mortality remain high in the United States although vaccination clearly improves health outcomes and reduces health expenditures. This study was designed to assess the effectiveness of mail and telephone reminder strategies on improving existing clinic influenza vaccination rates among those not seeking early seasonal vaccination.

Methods: In mid-November, we randomized 1371 patients at a hypertension clinic into 1 of 2 intervention groups, a mail reminder group (letter plus the Centers for Disease Control [CDC] Influenza Vaccine Information Statement) or a phone reminder group (same information via a personal phone call), or a control group.

Hypertension: issues in control and resistance.

Hypertension remains uncontrolled in more than 50% of treated patients. Barriers to hypertension control include those that are patient-related, physician-related, and related to the health system. Identification of uncontrolled hypertension, pseudoresistant hyper-tension, and resistant hypertension require thoughtful attention to accurate blood pressure measurement, lifestyle factors, evaluation for secondary causes of hypertension, and proper treatment.

Does socioeconomic status affect blood pressure goal achievement?

Hypertension is a major cause of disease burden in all racial, ethnic, and socioeconomic groups in developing and developed regions and countries. Differences in blood pressure likely begin early in life and reflect a complex relationship of biologic, genetic, social, and environmental interactions. The relationship between socioeconomic status and hypertension is complex and difficult to measure.

The treatment of hypertension in obese patients.

Hypertension causes a significant disease burden in all racial and ethnic groups and is directly attributable to excess weight in most cases. The relationship between increasing body mass index and hypertension prevalence has been recognized for decades. Epidemiologic studies clearly demonstrate the correlation between body weight and blood pressure in obese and lean populations.

Racial and ethnic differences in hypertension.

Hypertension is a major cause of disease burden in all racial and ethnic groups and in both developing and developed regions and countries. Much of the racial and ethnic disparity in cardiovascular outcomes can be attributed to the excess burden of hypertension. Racial and ethnic differences in blood pressure occur because of biology and sociology.

Exercise, insulin resistance, and hypertension: a complex relationship.

More than 300,000 deaths occur annually in the United States alone as a result of obesity, poor dietary habits, or physical inactivity. Obesity is now an increasingly recognized independent risk factor for cardiovascular disease and leads to numerous other comorbidities. The causal relationships between obesity and both insulin resistance and hypertension have been consistently demonstrated in numerous studies.

Relationship between antihypertensive drugs and metabolic syndrome.

Metabolic syndrome is a cluster of risk factors associated with an increased risk for cardiovascular disease and type 2 diabetes. Based on data from 1988 to 1994, it is estimated that 24% of adults in the United States meet the criteria for diagnosis of metabolic syndrome. The use of certain medications increases the risk for metabolic syndrome by either promoting weight gain or the development of changes in lipid or glucose metabolism.

Prevalence, awareness, treatment, and control of hypertension in the Jackson Heart Study.

African Americans have higher reported hypertension prevalence and lower control rates than other ethnic groups in the United States. Hypertension prevalence, awareness, treatment, and control (outcomes) and potentially associated demographic, lifestyle, comorbidity, and health care access factors were examined in 5249 adult participants (3362 women and 1887 men) aged 21 to 94 years enrolled in the Jackson Heart Study. Hypertension prevalence (62.

A Katrina experience: lessons learned.

Purpose: Almost no data exist on how best to respond to the medical needs of civilians displaced by natural disasters. After Hurricane Katrina destroyed the Gulf Coast and seriously damaged the infrastructure of Jackson, Miss, the University of Mississippi Medical Center (UMMC) was challenged with serving a large group of evacuees at a major Red Cross evacuation shelter near our campus. We reviewed our experiences and share lessons learned.

Serum uric acid predicts incident hypertension in a biethnic cohort: the atherosclerosis risk in communities study.

Serum uric acid has been positively associated with incident hypertension, but previous studies have had limited ability to explore this relationship across sex and ethnic strata. We sought to evaluate this association in a biethnic cohort of middle-aged men and women. Participants in the Atherosclerosis Risk in Communities (ARIC) study who were free of hypertension at baseline (N=9104) were evaluated for hypertension at 3-year intervals over 4 examinations.

Drug-induced metabolic syndrome.

The metabolic syndrome is a cluster of risk factors associated with an increased risk for cardiovascular disease and type 2 diabetes. Based on data from 1988 to 1994, it is estimated that 24% of adults in the United States meet the criteria for diagnosis of the metabolic syndrome. The use of certain medications may increase the risk of the metabolic syndrome by either promoting weight gain or altering lipid or glucose metabolism.

Metabolic syndrome and insulin resistance in the TROPHY sub-study: contrasting views in patients with high-normal blood pressure.

Background: Although insulin resistance and metabolic syndrome are often used synonymously, concordance is not established.

Methods: Metabolic, hemodynamic, and hormonal data were analyzed on 141 patients in the Trial of Preventing Hypertension (TROPHY) Sub-Study with high-normal blood pressure (BP) (130 to 139/85 to 89 mm Hg [mean +/- SD, 133 +/- 8/85 +/- 6 mm Hg]; age, 48 +/- 9 years; body mass index 30 +/- 5 kg/m(2)).

Results: Fifty-three of 141 subjects (37.

Pathophysiology and treatment of obesity hypertension.

Excess weight gain accounts for as much as 65-75% of the risk for essential hypertension and also greatly increases the risk for end stage renal disease (ESRD). Obesity raises blood pressure by increasing renal tubular reabsorption, impairing pressure natriuresis, and causing volume expansion due to activation of the sympathetic nervous system (SNS) and renin-angiotensin aldosterone system (RAAS), and by physical compression of the kidneys, especially when visceral obesity is present. The mechanisms of SNS activation in obesity are still unclear but may be due, in part, to hyperleptinemia that stimulates the hypothalamic pro-opiomelanocortin (POMC) pathway.
