BACKGROUND AND OBJECTIVE: Salt-sensitive (SS) patients more frequently showed a nondipper blood pressure pattern and were associated with more serious target organ damage than non-SS patients. We aimed to investigate whether potassium supplement can improve the blunted nocturnal blood pressure fall in SS patients exposed to a high-salt diet. PATIENTS AND METHODS: Approximately 49 normotensive and mildly hypertensive Chinese patients received a study protocol of a 3 days of baseline examination, 7 days of a low-salt diet (3 g NaCl/day), 7 days of a high-salt diet (18 g NaCl/day), and 7 days of a high-salt diet with a potassium supplement (18 g NaCl and 4...

Obstructive sleep apnoea (OSA) is very common in patients with Type 2 diabetes (T2D), which is not surprising considering that obesity is a common risk factor for both conditions. In general population studies, OSA has been shown to be associated with several comorbidities including increased risk of road traffic accidents, T2D, hypertension and lack of nocturnal dipping of blood pressure, hyperlipidaemia, increased inflammation, increased risk of cardiovascular disease and mortality, increased risk of atrial fibrillation, worse quality of life, and erectile dysfunction...

BACKGROUND: Brain-derived neurotrophic factor (BDNF) has been shown to have protective effects against cardiovascular diseases and death through neural and non-neural pathways via tropomyosin-related kinase B signaling. However, it is not known whether plasma BDNF concentration is a predictor of chronic kidney disease (CKD). DESIGN: This study was conducted as a prospective cohort study as part of the Hyogo Sleep Cardio-Autonomic Atherosclerosis. METHODS: We measured plasma BDNF concentration in 324 patients without CKD, defined as an estimated glomerular filtration rate (eGFR) less than 60 ml/min/1...

Obstructive sleep apnea (OSA) often precedes cardiovascular disease, partly due to treatment resistant hypertension. The nocturnal apneas of OSA trigger increased sympathetic nervous discharge during both sleep and wakefulness. Apneas also trigger cardiac release of the endogenous diuretic atrial natriuretic peptide. We hypothesized that treatment of the excess sympathetic nervous activity of OSA with a β1 blocker would lower 24 h blood pressure (BP) more than diuretic therapy. Subjects with OSA associated hypertension received 2 weeks of placebo followed by the β1 blocker nebivolol or hydrochlorothiazide (HCTZ) for 6 weeks in a blinded crossover study...

Aging is an emerging worldwide threat to public health, even in the workplace, as it links with risk of illness and death. Bewildered inflammatory responses and stressful conditions associate with age-related disorders. Additionally, circadian rhythm disruption, a critical health issue in night-shift workers, correlates with premature aging. We investigated the hypothesis of a link between altered inflammatory response, detected by plasmatic long pentraxin 3 (PTX3), and biological aging, measured by leukocyte telomere length (LTL), attrition, and possibly induced by night-shift work...

BACKGROUND: We examined the reproducibility of differences in ambulatory blood pressure (BP) monitoring (ABPM) phenotypes and other parameters (sustained hypertension, masked hypertension, nocturnal hypertension, and nondipping) between African Americans and Whites. METHODS: A total of 420 participants untreated for hypertension attended 2 research visits 1 week apart during which traditional office BP averages and ABPM session averages were determined. We computed percent agreement in ABPM phenotypes across the 2 visits stratified by race and associated kappa statistics with 95% confidence intervals...

INTRODUCTION: Ambulatory blood pressure monitoring by automatic device is the best blood pressure evaluation method and sleep apnea syndrome is the leading cause of poor control. Oximetry allows screening these individuals but its usefulness has been poorly explored in Primary Health Care. The aim was to evaluate the blood pressure control at the office and with ambulatory blood pressure monitoring by automatic device and to relate it to sleep apnea syndrome. MATERIAL AND METHODS: We selected a sample of 50 participants, representative of 3036 hypertensive patients...

OBJECTIVE: Obstructive sleep apnea (OSA) is a risk factor for hypertension. The SKUP(3) study showed that modified uvulopalatopharyngoplasty (UPPP) significantly improved nocturnal respiration, sleepiness, and quality of life. The aim of this study was to evaluate the impact of surgery on blood pressure in patients with OSA. METHODS: We used a single-center randomized controlled trial to compare modified UPPP with controls at baseline and after six months. The controls received delayed surgery with an additional six-month follow-up...

Arterial hypertension (HT) plays an important role and is a major factor in the occurrence and progression of chronic graft nephropathy. We evaluated 24-hour blood pressure (BP) profile in kidney transplant patients to identify factors predictive of abnormal circadian BP profile. BP was measured over a period of 24 hours using a noninvasive automatic device (EC-3H / ABPM) in 40 renal transplant patients (mean age = 37.2±12.2 years, M = 30, mean serum creatinine = 2.0±1.4 mg/dl). They were under the triple immunosuppressive therapy (CsA / Ts + Aza / MMF + PDN)...

The aim of this study was to analyze the influence of the number of visits and the number of blood pressure (BP) measurements on the prevalence of high blood pressure (HBP) in adolescents. A cross-sectional epidemiologic study with 481 adolescents (14-19 years old) selected using a random cluster sampling strategy. We measured the BP three times in a first visit. Adolescents with HBP performed subsequent visits. The final calculation of BP followed four strategies: the 1st measure, mean of 1st and 2nd measurements, mean of all three measurements, and averaging the 2nd and 3rd measurements...

REVIEW
Walter T McNicholas
Chronic obstructive pulmonary disease (COPD) and obstructive sleep apnea syndrome (OSA) are both highly prevalent, which implies that both disorders occurring together (overlap syndrome) is likely to be common based on chance association alone. However, different clinical COPD phenotypes influence the likelihood of co-existing OSA in that the increased lung volumes and low body mass index (BMI) associated with the predominant emphysema phenotype protects against OSA, whereas the higher likelihood of peripheral edema and increased BMI associated with the predominant chronic bronchitis phenotype promotes OSA...

OBJECTIVE: Obstructive sleep apnea (OSA) has been identified as the most common secondary contributing factor for the development and worsening of hypertension. However, the underlying relationships between blood pressure variability (BPV) and OSA are still not very clear. Therefore, we investigated the influences of OSA on BPV in hypertensive patients and explored the potential pathophysiologic mechanisms. PARTICIPANTS AND METHODS: Ambulatory blood pressure (BP) monitoring was carried out and polysomnography was performed to detect sleep apnea...
