Background Moxibustion is a traditional East Asian medical therapy that uses the heat generated by burning herbal preparations containing Artemisia vulgaris to stimulate acupuncture points. The aim of this review was to evaluate previously published clinical evidence for the use of moxibustion as a treatment for hypertension. Methods We searched 15 databases without language restrictions from their respective dates of inception until March 2010. We included randomized controlled trials (RCTs) comparing moxibustion to either antihypertensive drugs or no treatment. The risk of bias was assessed for each RCT. Results During the course of our search, we identified 519 relevant articles. A total of 4 RCTs met all the inclusion criteria, two of which failed to report favorable effects of moxibustion on blood pressure (BP) compared to the control (antihypertensive drug treatment alone). However, a third RCT showed significant effects of moxibustion as an adjunct treatment to antihypertensi...

The global prevalence of dementia has been estimated to be as high as 24 million, and is predicted to double every 20 years until at least 2040. As the population worldwide continues to age, the number of individuals at risk will also increase, particularly among the very old. Alzheimer disease is the leading cause of dementia beginning with impaired memory. The neuropathological hallmarks of Alzheimer disease include diffuse and neuritic extracellular amyloid plaques in brain that are frequently surrounded by dystrophic neurites and intraneuronal neurofibrillary tangles. The etiology of Alzheimer disease remains unclear, but it is likely to be the result of both genetic and environmental factors. In this review we discuss the prevalence and incidence rates, the established environmental risk factors, and the protective factors, and briefly review genetic variants predisposing to disease.

In the management of hypertension, blood pressure (BP) monitoring and medication use are key strategies, but they are dependent on patients' motivation to practice self-care. To gauge patients' approaches to monitoring their blood pressure, as well as explore their attitudes toward, and actions relating to, high blood pressure readings, as the key components of their self-management of hypertension. This qualitative study, comprising individual telephone interviews, involved patients attending community pharmacies in Sydney (Australia). Patients' perspectives were elicited using a purpose-designed, semi-structured interview guide. The verbal responses were audio-recorded, transcribed verbatim, and thematically analysed. Three key themes arose: (1) approaches to monitoring blood pressure, (2) attitudes to variability in BP, (3) responses to high BP readings. Many patients self-regulated the frequency of monitoring based on perceived need and/or opportunity. Most were indi...

The prevalence and short-term outcomes of hypertensive urgency (systolic blood pressure ≥180 mm Hg and/or diastolic blood pressure ≥110 mm Hg) are unknown. Guidelines recommend achieving blood pressure control within 24 to 48 hours. However, some patients are referred to the emergency department (ED) or directly admitted to the hospital, and whether hospital management is associated with better outcomes is unknown. To describe the prevalence of hypertensive urgency and the characteristics and short-term outcomes of these patients, and to determine whether referral to the hospital is associated with better outcomes than outpatient management. This retrospective cohort study with propensity matching included all patients presenting with hypertensive urgency to an office in the Cleveland Clinic Healthcare system from January 1, 2008, to December 31, 2013. Pregnant women and patients referred to the hospital for symptoms or treatment of other conditions were excluded. Final follow-up wa...

The spectrum of left ventricular geometric adaptation to hypertension was investigated in 165 patients with untreated essential hypertension and 125 age- and gender-matched normal adults studied by two-dimensional and M-mode echocardiography. Among hypertensive patients, left ventricular mass index and relative wall thickness were normal in 52%, whereas 13% had increased relative wall thickness with normal ventricular mass (“concentric remodeling”), 27% had increased mass with normal relative wall thickness (eccentric hypertrophy) and only 8% had “typical” hypertensive concentric hypertrophy (increase in both variables).Systemic hemodynamics paralleled ventricular geometry, with the highest peripheral resistance in the groups with concentric remodeling and hypertrophy, whereas cardiac index was supernormal in those with eccentric hypertrophy and low normal in patients with concentric remodeling. The left ventricular shortaxis/long-axis ratio was positively related to stroke volume (r = 0.45, p < 0.001), with cavity shape most elliptic in patients with concentric remodeling and most spheric in those with eccentric hypertrophy. Normality of left ventricular mass in concentric remodeling appeared to reflect offsetting by volume “underload” of the effects of pressure overload, whereas eccentric hypertrophy was associated with concomitant pressure and volume overload.Thus, arterial hypertension is associated with a spectrum of cardiac geometric adaptation matched to systemic hemodynamics and ventricular load. Concentric left ventricular remodeling and eccentric hypertrophy are more common than the typical pattern of concentric hypertrophy in untreated hypertensive patients.

To examine the association of body mass index (BMI), triceps skinfold thickness (TST) and percentage body fat (%BF) from bioelectrical impedance analysis (BIA) with blood lipids, systolic blood pressure (SBP) and diastolic blood pressure (DBP) in children. Cross-sectional study was conducted on 1280 schoolchildren aged 8-11 years from the Cuenca province (Spain). Data collection was conducted under standardized conditions, taking several measurements of each variable to enhance accuracy. Analyses were performed using age-adjusted correlation coefficients, and multiple linear regression adjusted for age, BMI, TST and %BF. Correlations between %BF and apolipoprotein (apo) B, total cholesterol, low-density lipoprotein cholesterol (LDL-c), total cholesterol/HDL-c ratio and DBP were higher than those for BMI and TST. In contrast, the correlations between BMI, and apo A-I and SBP were higher than those for %BF and TST. The results were similar across the sexes. The correlations between each of the three measures of body fatness, and blood lipids and blood pressure were highest in children with greatest BMI and %BF. When analyses were adjusted for the three body fatness measures, %BF showed stronger associations than did BMI or TST with blood lipids and blood pressure, with the exception of apo A-I and SBP, which were more closely associated with BMI. %BF from BIA is more strongly associated than either BMI or TST with most of the blood lipid fractions in schoolchildren aged 8-11 years.

Objectives: To assess the risk of obstructive sleep apnea (OSA) and its associated risk factors among patients with type 2 diabetes in the south of Saudi Arabia. Methodology: This is a cross-sectional study conducted in the Armed Forces Hospital in Jazan. The prevalence of OSA was assessed through a validated Arabic translation of the STOP-BANG screening questionnaire. The odds of a higher OSA risk were calculated via regression analysis according to the measured clinical and demographic variables. Results: The total number of participants was 306, of which 213 (70%) were over the age of 50; 247 (81%) were married, and 161 (53%) were females. The overall median score of the OSA risk level assessed by the STOP-BANG items was three on a scale of 0-8 of which 193 (63.1%) of the participants in the sample were classified as being at high risk of developing OSA. Several statistically significant associations were identified where odds ratios (ORs) with a higher OSA risk level were detected according to age, gender, social status, waist and neck circumference, hemoglobin A1c (HbA1c) and body mass index (BMI) levels, duration of diabetes, and comorbidity with hypertension (p-values <0.05). Conclusions: The higher risk of OSA identified in our sample of diabetic patients can be related to a high prevalence of obesity, larger neck circumferences, hypertension, and other factors related to the duration and treatment of diabetes. Additionally, the association between waist circumference, HbA1c, and duration since the diagnosis of diabetes suggests an interaction effect requiring further investigations.

Considering the growing body of evidence that indicates the contribution of superoxide anions (O2) and other reactive oxygen species (ROS) to the development of hypertension, we assessed whether animal models of hypertension have a benefic effect with tempol, a superoxide dismutase mimetic, to help augment the design of future studies. Studies published between July 1998 and December 2012 on blood pressure (BP) in different hypertensive models were obtained after an electronic and manual search of PubMed. In-depth analyses of the methodological quality of the studies and the mean arterial pressure (MAP) changes after treatment with tempol were performed, as well as the subgroup analyses on the route of tempol delivery. Out of the 144 identified studies, 28 were included after screening. The data showed that tempol reduced MAP by computing the standardized mean difference with the value of 4.622 (95% confidence interval 3.24-5.99). The quality of studies included in the meta-analysis was category II; however, omission of details in the trials might have biased the results. There was substantial heterogeneity in the results with an I of 94.45%, which persisted after stratifying for the route of tempol delivery. In conclusion, this analysis shows that antioxidant treatment with tempol can reduce BP, suggesting that ROS plays a role in the pathogenesis of increased BP in the hypertension models used in the current research practice.

The purpose of this investigation was to evaluate the extent to which obesity and/or hypertension may modify the response of rats' periodontium to chronic gingival irritation. Forty-four normal, spontaneously hypertensive, obese, and obese-hypertensive rats were used. Histopathologic evaluation of the periodontal structure showed both hyperplasia and hypertrophy of the walls of blood vessels supplying the periodontium in the hypertensive and obese-hypertensive animals. The results also indicated that obesity significantly contributed to e severity of periodontal disease. Hypertension alone was not a significant factor. The obese-hypertensive rats showed the most severe periodontal response to local irritation.

Nonsteroidal anti-inflammatory drug (NSAID) side effects can impair quality of life in patients with osteoarthritis. Due to its particular mechanism of action, paracetamol might bypass these negative effects. To determine both the role of paracetamol in the treatment of osteoarthritis patients and optimal combination of antihypertensives and antirheumatics for these patients. A prospective clinical trial in a family practice included 110 treated hypertensives aged over 55 years: 50 controls and 60 also taking NSAIDs for osteoarthritis. This 3-month study compared two antihypertensives, lisinopril/hydrochlorothiazide fixed combination and amlodipine, with two NSAIDs, ibuprofen and piroxicam, and with paracetamol. Following clinical work-up and NSAID discontinuation for at least 3 days (run-in period of only 3-7 days), osteoarthritis subjects were randomized to 1-month periods of ibuprofen (400-600 mg t.i.d.) or piroxicam (10-20 mg o.d.) with one month of paracetamol (1000 mg t.i.d.) ...

Aim of the study was to detect the prevalence of hypertension among 11-14 years old schoolchildren (n. 487, mean age 12.7 +/- 0.9). The influence on blood pressure (BP) of body mass index (BMI), dietary habits (frequency of breakfast and food items consumption) and life-style was also investigated. Hypertension was defined according to blood pressure tables for children and adolescents of the NIH-Fourth Report (systolic and diastolic BP >95th percentile for age and sex). Overweight and obesity were determined according to the International Obesity Task Force Dietary habits and life-style were investigated by specific questionnaires. The prevalence of overweight and obesity was respectively 31.8% and 10.3% of the subjects studied. Moreover 10.3% of them showed BP values between 90th and 95th percentile and 10.1% was hypertensive. In general the prevalence of overweight (p < 0.05), obesity (p < 0.001) and sedentary activity (p < 0.05) was higher in hypertensive adolescents...

The appropriate treatment target for systolic blood pressure (SBP) in older patients with hypertension remains uncertain. To evaluate the effects of intensive (<120 mm Hg) compared with standard (<140 mm Hg) SBP targets in persons aged 75 years or older with hypertension but without diabetes. A multicenter, randomized clinical trial of patients aged 75 years or older who participated in the Systolic Blood Pressure Intervention Trial (SPRINT). Recruitment began on October 20, 2010, and follow-up ended on August 20, 2015. Participants were randomized to an SBP target of less than 120 mm Hg (intensive treatment group, n = 1317) or an SBP target of less than 140 mm Hg (standard treatment group, n = 1319). The primary cardiovascular disease outcome was a composite of nonfatal myocardial infarction, acute coronary syndrome not resulting in a myocardial infarction, nonfatal stroke, nonfatal acute decompensated heart failure, and death from cardiovascular causes. All-cause mortality w...
