    After the 2003 publication of the Seventh Report of the Joint National Committee on Prevention, Detection, Evaluation, and Treatment of High Blood Pressure (JNC 7) guidelines, there was a 5-10% increase in patients initiating antihypertensive medication with a thiazide-type diuretic, but most patients still did not initiate treatment with this class. There are few contemporary published data on antihypertensive medication classes filled by patients initiating treatment. We used the 5% random Medicare sample to study the initiation of antihypertensive medication between 2007 and 2010. Initiation was defined by the first antihypertensive medication fill preceded by 365 days with no antihypertensive medication fills. We restricted our analysis to beneficiaries ≥ 65 years who had two or more outpatient visits with a hypertension diagnosis and full Medicare fee-for-service coverage for the 365 days prior to initiation of antihypertensive medication. Between 2007 and 2010, 32,142 beneficiaries in the 5% Medicare sample initiated antihypertensive medication. Initiation with a thiazide-type diuretic decreased from 19.2% in 2007 to 17.9% in 2010. No other changes in medication classes initiated occurred over this period. Among those initiating antihypertensive medication in 2010, 31.3% filled angiotensin-converting enzyme inhibitors (ACE-Is), 26.9% filled beta blockers, 17.2% filled calcium channel blockers, and 14.4% filled angiotensin receptor blockers (ARBs). Initiation with >1 antihypertensive medication class decreased from 25.6% in 2007 to 24.1% in 2010. Patients initiated >1 antihypertensive medication class most commonly with a thiazide-type diuretic and either an ACE-I or ARB.

    Telemedicine-based medication management improves hypertension control, but has been evaluated primarily in patients with low antihypertensive drug counts. Its impact on patients taking three or more antihypertensive agents is not well-established. To address this evidence gap, the authors conducted an exploratory analysis of an 18-month, 591-patient trial of telemedicine-based hypertension medication management. Using general linear models, the effect of medication management on blood pressure for patients taking two or fewer antihypertensive agents at study baseline vs those taking three or more was compared. While patients taking two or fewer antihypertensive agents had a significant reduction in systolic blood pressure with medication management, those taking three or more had no such response. The between-subgroup effect difference was statistically significant at 6 months (-6.4 mm Hg [95% confidence interval, -12.2 to -0.6]) and near significant at 18 months (-6.0 mm Hg [95% confidence interval, -12.2 to 0.2]). These findings suggest that baseline antihypertensive drug count may impact how patients respond to hypertension medication management and emphasize the need to study management strategies specifically in patients taking three or more antihypertensive medications.

    2011-01-01

    Background Several studies showed that blood pressure and lung function are associated. Additionally, a potential effect of antihypertensive medication, especially beta-blockers, on lung function has been discussed. However, side effects of beta-blockers have been investigated mainly in patients with already reduced lung function. Thus, aim of this analysis is to determine whether hypertension and antihypertensive medication have an adverse effect on lung function in a general adult population. Methods Within the population-based KORA F4 study 1319 adults aged 40-65 years performed lung function tests and blood pressure measurements. Additionally, information on anthropometric measurements, medical history and use of antihypertensive medication was available. Multivariable regression models were applied to study the association between blood pressure, antihypertensive medication and lung function. Results High blood pressure as well as antihypertensive medication were associated with lower forced expiratory volume in one second (p = 0.02 respectively p = 0.05; R2: 0.65) and forced vital capacity values (p = 0.01 respectively p = 0.05, R2: 0.73). Furthermore, a detailed analysis of antihypertensive medication pointed out that only the use of beta-blockers was associated with reduced lung function, whereas other antihypertensive medication had no effect on lung function. The adverse effect of beta-blockers was significant for forced vital capacity (p = 0.04; R2: 0.65), while the association with forced expiratory volume in one second showed a trend toward significance (p = 0.07; R2: 0.73). In the same model high blood pressure was associated with reduced forced vital capacity (p = 0.01) and forced expiratory volume in one second (p = 0.03) values, too. Conclusion Our analysis indicates that both high blood pressure and the use of beta-blockers, but not the use of other antihypertensive medication, are associated with reduced lung function in a general adult

    Full Text Available The purpose of this study was to establish a risk stratification model for identifying Chinese immigrants at risk for non-adherence to antihypertensive medications. Questionnaires were self-administered to 200 Chinese immigrants in San Francisco, USA. Questionnaires included demographics, culture factors (e.g., Perceived Susceptibility in General, Perceived Benefits of Western Medication, Perceived Benefits of Chinese Herbs, and Health-Related Social Support, and medications adherence. Participants' mean age was 70.6 (±10.3 years. Three stratification factors were identified for non-adherence: Lower Perceived Susceptibility in General, lower Perceived Benefit of Western Medications, and longer Length of Stay in the United States. The probability of non-adherence was 77%, 62%, and 57% for lower perceived susceptibility, longer stay in the United States, and lower perceived benefits of Western medications, respectively. A combination of lower perceived susceptibility and lower perceived benefits of medication predicted 81% non-adherence and lower perceived susceptibility with longer stay in the United States predicted at 84%. All three factors combined predicted nearly 90%. Patients with all three factors had the highest risk for non-adherence. The second priority groups are patients with lower perceived susceptibility and those with lower perceived susceptibility combined with any of the other two factors. In the clinical setting, these three groups are a high priority for education on the importance of medication adherence.

    Early aortic stenting in chronic type B aortic dissection (TBAD) may lead to long-term benefit, although the optimal treatment strategy is hotly debated. A robust comparison to outcomes seen in medically managed patients is challenging as the rate of antihypertensive medication adherence is unknown. The aims of this study were therefore to identify the rate of antihypertensive medication adherence and predictors of adherence in TBAD. This was a cross-sectional mixed methods study of patients with TBAD. Medication adherence was assessed by the eight-item Morisky Medication Adherence Scale together with an assessment of demographic, behavioral, and psychological variables and disease-specific knowledge. There were 47 patients (mean age, 59 years; 81% male) who were recruited from a tertiary vascular unit. The mean total number of medications taken was 5.8 (2-14), and the mean number of antihypertensive medications was 1.9 (1-6). Of the 47 patients, 20 (43%) reported high levels of medication adherence, 17 (36%) reported moderate adherence, and 10 (21%) reported low adherence. Previous aortic surgery was associated with higher levels of adherence (β = 0.332; P = .03), as was taking a greater number of medications (β = 0.332; P = .026), perceived benefit from treatment (β = 0.486; P debate; one cannot robustly compare two strategies when half of a treatment group may not be receiving the stated intervention. To develop an evidence-based treatment strategy for TBAD, we must take into account the direct and indirect effects of medical therapy and thoracic endovascular aortic repair. Further work to improve medication adherence and to understand its impact on disease progression is vital to inform the debate and to deliver the best outcomes for patients.

    We studied the utility of ABPM in patients with elevated clinic BP on 1-2 antihypertensive medications (group B, N=117), compared with those on no medications (group A, N=76) and on > or =3 medications (group C, N=110). 35% of patients in group B had adequately controlled 24-h BP based on ABPM, compared with 22.4% in group A (P=0.06) and 19.1% in group C (P=0.007). Antihypertensive treatment was not escalated in patients with adequately controlled BP. This suggests that ABPM has an important role in therapeutic decision-making for patients on 1-2 antihypertensive medications.

    Successful control of blood pressure relies on identification of secondary causes and contributing factors of hypertension. As antihypertensive medication can interfere with diagnostic investigations, temporary discontinuation of medication is advised. However, there are concerns about the safety of temporary discontinuation of antihypertensive medication in patients with difficult-to-control hypertension. We assessed the occurrence of adverse cardiovascular and cerebrovascular events potentially attributable to temporary discontinuation of antihypertensive medication between February 2010 and March 2016 (n=604) in our Analysis of Complicated Hypertension screening program. A reference group (n=604) was extracted from the SMART study (Second Manifestations of Arterial Disease) cohort (comprising a similar cohort at our hospital in whom medication was not stopped) and individually matched for blood pressure, age, sex, and history of cardiovascular disease. Discontinuation of medication was well tolerated; 62% reported no complaints, 24% had mild discomfort that could be left untreated, and 14% experienced complaints that required prescription of antihypertensive escape medication. Three major adverse events were observed in the Analysis of Complicated Hypertension group between discontinuation of medication and 30 days after restart of medication (event rate=31.2 events per 1000 patient-year). In the reference cohort, 5 cardiovascular events were observed during a similar follow-up period (event rate=51.2 events per 1000 patient-year). In conclusion, discontinuation of antihypertensive medication for the diagnostic evaluation of hypertension does not increase the acute risk of cardiovascular events when performed in a well-controlled setting in specialized hospitals with appropriate protocols for monitoring safety. © 2017 American Heart Association, Inc.

    Full Text Available While hypertension is a common and treatable health problem, adherence to antihypertensive medication remains a challenge. This study examines the hypothesis that workplace social capital may influence adherence to antihypertensive medication among hypertensive employees.We linked survey responses to nationwide pharmacy records for a cohort of 3515 hypertensive employees (mean age 53.9 years, 76% women who required continuous antihypertensive drug therapy (the Finnish Public Sector study. A standard scale was used to measure workplace social capital from co-workers' assessments and self-reports in 2000-2004. Non-adherence to antihypertensive medication was determined based on the number of days-not-treated at the year following the survey using comprehensive prescription records. Negative binomial regression models were conducted adjusting for socio-demographic characteristics, duration of hypertension, behaviour-related risk factors, and co-morbid conditions. The overall rate of days-not-treated was 20.7 per person-year (78% had no days-not-treated. Higher age, obesity, and presence of somatic co-morbidities were all associated with better adherence, but this was not the case for co-worker-assessed or self-reported workplace social capital. The rate of days-not-treated was 19.7 per person-year in the bottom fourth of co-worker-assessed workplace social capital, compared to 20.4 in the top fourth. The corresponding rate ratio from the fully-adjusted model was 0.95 (95% confidence interval (CI 0.58-1.56. In a subgroup of 907 new users of antihypertensive medication this rate ratio was 0.98 (95% CI 0.42-2.29.We found no consistent evidence to support the hypothesized effect of workplace social capital on adherence to drug therapy among employees with chronic hypertension.

    Background Antihypertensive medication use has been associated with an increased risk of falls in some but not all studies. Few data are available on the short-term risk of falls following antihypertensive medication initiation and intensification. Methods and Results We examined the association between initiating and intensifying antihypertensive medication and serious fall injuries in a case-crossover study of 90,127 Medicare beneficiaries who were ≥65 years old and had a serious fall injury between July 1, 2007 and December 31, 2012, based on emergency department and inpatient claims. Antihypertensive medication initiation was defined by a prescription fill with no fills in the prior year. Intensification was defined by the addition of a new antihypertensive class, and, separately, titration by the addition of a new class or increase in dosage of a current class. Exposures were ascertained for the 15 days before the fall (case period) and six 15-day earlier periods (control periods). Overall, 272, 1508, and 3113 Medicare beneficiaries initiated, added a new class of antihypertensive medication or titrated therapy, respectively, within 15 days of their serious fall injury. The odds for a serious fall injury was increased during the 15 days following antihypertensive medication initiation [odds ratio, OR, 1.36 (95% CI 1.19, 1.55)], adding a new class [OR 1.16 (95% CI 1.10, 1.23)], and titration [OR 1.13 (95% CI 1.08, 1.18)]. These associations were attenuated beyond 15 days. Conclusions Antihypertensive medication initiation and intensification was associated with a short-term, but not long-term, increased risk of serious fall injuries among older adults. PMID:27166208

    Non-compliance to anti-hypertensive drugs can have negative impact on cardiovascular outcome. Various studies have been conducted on the issue but the factors are not yet explored properly, particularly in Pakistan. This study was conducted to determine the frequency and factors associated with non-compliance to anti-hypertensive medications in Karachi. Methods: This descriptive cross sectional study was conducted on 113 indoor hypertensive patients included by purposive sampling, aged 30 years and above diagnosed at least 6 months back in public sector tertiary care institutes of Karachi from March to October 2011. Data was collected through a questionnaire in Urdu. Demographic data, hypertension diagnosis, medical co-morbidity, current number of anti-hypertensive medicines, frequency of missing prescribed antihypertensive therapy and other factors affecting compliance pertaining to medicines, patient, physician and health care centre were included in the questionnaire. Results: This study revealed that 68.14% patients were non-compliant. Non-compliance was found to be associated with gender and socioeconomic status. Duration of hypertension, duration between follow up visits to physician, number of drugs, careless attitude, role of physician and limiting access to health care center are found to be important factors in non-compliance. Conclusions: Multiple factors including patients, medicine and health care system related, which can be prevented with simple measures, were found responsible for higher prevalence of non-compliance against anti-hypertensive medicines.

    To compare the use of antihypertensive medications and diagnostic tests among adolescents and young adults with primary versus secondary hypertension. We conducted retrospective cohort analysis of claims data for adolescents and young adults (12-21 years of age) with ≥3 years of insurance coverage (≥11 months/year) in a large private managed care plan during 2003-2009 with diagnosis of primary hypertension or secondary hypertension. We examined their use of antihypertensive medications and identified demographic characteristics and the presence of obesity-related comorbidities. For the subset receiving antihypertensive medications, we examined their diagnostic test use (echocardiograms, renal ultrasounds, and electrocardiograms). The study sample included 1,232 adolescents and young adults; 84% had primary hypertension and 16% had secondary hypertension. The overall prevalence rate of hypertension was 2.6%. One quarter (28%) with primary hypertension had one or more antihypertensive medications, whereas 65% with secondary hypertension had one or more antihypertensive medications. Leading prescribers of antihypertensives for subjects with primary hypertension were primary care physicians (80%), whereas antihypertensive medications were equally prescribed by primary care physicians (43%) and sub-specialists (37%) for subjects with secondary hypertension. The predominant hypertension diagnosis among adolescents and young adults is primary hypertension. Antihypertensive medication use was higher among those with secondary hypertension compared with those with primary hypertension. Further study is needed to determine treatment effectiveness and patient outcomes associated with differential treatment patterns used for adolescents and young adults with primary versus secondary hypertension.

    the relationship between antihypertensive medication and orthostatic hypotension in older persons remains ambiguous, due to conflicting observational evidence and lack of data of clinical trials. to assess the effect of discontinuation of antihypertensive medication on orthostatic hypotension in older persons with mild cognitive impairment. a total of 162 participants with orthostatic hypotension were selected from the Discontinuation of Antihypertensive Treatment in Elderly people (DANTE) Study. This randomised clinical trial included community-dwelling participants aged ≥75 years, with mild cognitive impairment, using antihypertensive medication and without serious cardiovascular disease. Participants were randomised to discontinuation or continuation of antihypertensive treatment (ratio 1:1). Orthostatic hypotension was defined as a drop of at least 20 mmHg in systolic blood pressure and/or 10 mmHg in diastolic blood pressure on standing from a seated position. Outcome was the absence of orthostatic hypotension at 4-month follow-up. Relative risks (RR) were calculated by intention-to-treat and per-protocol analyses. at follow-up, according to intention-to-treat analyses, of the 86 persons assigned to discontinuation of antihypertensive medication, 43 (50%) were free from orthostatic hypotension, compared with 29 (38%) of the 76 persons assigned to continuation of medication [RR 1.31 (95% confidence interval (CI) 0.92-1.87); P = 0.13]. Per-protocol analysis showed that recovery from orthostatic hypotension was significantly higher in persons who completely discontinued all antihypertensive medication (61%) compared with the continuation group (38%) [RR 1.60 (95% CI 1.10-2.31); P = 0.01]. in older persons with mild cognitive impairment and orthostatic hypotension receiving antihypertensive medication, discontinuation of antihypertensive medication may increase the probability of recovery from orthostatic hypotension. © The Author 2016.

    We studied the blood pressure lowering effects of a bout of exercise and/or antihypertensive medicine with the goal of studying if exercise could substitute or enhance pharmacologic hypertension treatment. Twenty-three hypertensive metabolic syndrome patients chronically medicated with angiotensin II receptor 1 blockade antihypertensive medicine underwent 24-hr monitoring in four separated days in a randomized order; a) after taking their habitual dose of antihypertensive medicine (AHM trial), b) substituting their medicine by placebo medicine (PLAC trial), c) placebo medicine with a morning bout of intense aerobic exercise (PLAC+EXER trial) and d) combining the exercise and antihypertensive medicine (AHM+EXER trial). We found that in trials with AHM subjects had lower plasma aldosterone/renin activity ratio evidencing treatment compliance. Before exercise, the trials with AHM displayed lower systolic (130±16 vs 133±15 mmHg; P=0.018) and mean blood pressures (94±11 vs 96±10 mmHg; P=0.036) than trials with placebo medication. Acutely (i.e., 30 min after treatments) combining AHM+EXER lowered systolic blood pressure (SBP) below the effects of PLAC+EXER (-8.1±1.6 vs -4.9±1.5 mmHg; P=0.015). Twenty-four hour monitoring revealed no differences among trials in body motion. However, PLAC+EXER and AHM lowered SBP below PLAC during the first 10 hours, time at which PLAC+EXER effects faded out (i.e., at 19 PM). Adding exercise to medication (i.e., AHM+EXER) resulted in longer reductions in SBP than with exercise alone (PLAC+EXER). In summary, one bout of intense aerobic exercise in the morning cannot substitute the long-lasting effects of antihypertensive medicine in lowering blood pressure, but their combination is superior to exercise alone.

    Antihypertensive medication decreases risk of cardiovascular disease (CVD) events in adults with hypertension. Although black adults have higher prevalence of hypertension and worse CVD outcomes compared with whites, limited attention has been given to the cost-effectiveness of antihypertensive medication for blacks. To compare the cost-effectiveness of antihypertensive medication treatment versus no-treatment in white and black adults. We constructed a State Transition Model to assess the costs and quality-adjusted life-years (QALYs) associated with either antihypertensive medication treatment or no-treatment using data from the REasons for Geographic and Racial Differences in Stroke (REGARDS) study and published literature. CVD events and health states considered in the model included stroke, coronary heart disease, heart failure, chronic kidney disease, and end-stage renal disease. White and black adults with hypertension in the United States, 45 years of age and above. Yearly risk of CVD was determined using REGARDS data and published literature. Antihypertensive medication costs were determined using Medicare claims. Event and health state costs were estimated from published literature. All costs were adjusted to 2012 US dollars. Effectiveness was assessed using QALYs. Antihypertensive medication treatment was cost-saving and increased QALYs compared with no-treatment for white men ($7387; 1.14 QALYs), white women ($7796; 0.89 QALYs), black men ($8400; 1.66 QALYs), and black women ($10,249; 1.79 QALYs). Antihypertensive medication treatment is cost-saving and increases QALYs for all groups considered in the model, particularly among black adults.

    Clinical practice guidelines recommend different blood pressure (BP) goals for chronic kidney disease (CKD) patients. Usage of antihypertensive medication and attainment of BP targets in Asian CKD patients remain unclear. This study describes the profile of antihypertensive agents used and BP components in a multiethnic Asian population with stable CKD. Stable CKD outpatients with variability of serum creatinine levels 3 months apart, were recruited. Mean systolic blood pressure (SBP) and diastolic blood pressure (DBP) were measured using automated manometers, according to practice guidelines. Serum creatinine was assayed and the estimated glomerular filtration rate (GFR) calculated using the CKD Epidemiology Collaboration equation. BP and antihypertensive medication profile was examined using univariate analyses. 613 patients (55.1% male; 74.7% Chinese, 6.4% Indian, 11.4% Malay; 35.7% diabetes mellitus) with a mean age of 57.8 ± 14.5 years were recruited. Mean SBP was 139 ± 20 mmHg, DBP was 74 ± 11 mmHg, serum creatinine was 166 ± 115 µmol/L and GFR was 53 ± 32 mL/min/1.73 m(2). At a lower GFR, SBP increased (p < 0.001), whereas DBP decreased (p = 0.0052). Mean SBP increased in tandem with the number of antihypertensive agents used (p < 0.001), while mean DBP decreased when ≥ 3 antihypertensive agents were used (p = 0.0020). Different targets are recommended for each BP component in CKD patients. A majority of patients cannot attain SBP targets and/or exceed DBP targets. Research into monitoring and treatment methods is required to better define BP targets in CKD patients. Copyright: © Singapore Medical Association.

    To determine the prevalence of hypertension diagnosis in children of US military members and quantify echocardiography evaluations, cardiac complications, and antihypertensive prescriptions in the post-2004 guideline era. Using billing data from military health insurance (TRICARE) enrollees, hypertension cases were defined as 2 or more visits with a primary or unspecified hypertension diagnosis during any calendar year or 1 such visit if with a cardiologist or nephrologist. During 2006-2011, the database contained an average 1.3 million subjects aged 2-18 years per year. A total of 16 322 met the definition of hypertension (2.6/1000). The incidence of hypertension increased by 17% between 2006 and 2011 (from 2.3/1000 to 2.7/1000; P Hypertension was more common in adolescents aged 12-18 years than in younger children (5.4/1000 vs 0.9/1000). Among patients with hypertension, 5585 (34%) underwent echocardiography. The frequency of annual echocardiograms increased from 22.7% to 27.7% (P hypertension, 6353 (38.9%) received an antihypertensive medication. The prevalence of hypertension in children has increased. Compliance with national guidelines is poor. Of pediatric patients with hypertension who receive an echocardiogram, 1 in 12 had identified cardiac complications, supporting the current recommendations for echocardiography in children with hypertension. Less than one-half of children with hypertension are treated with medication. Published by Elsevier Inc.

    Around 200 million adults in China have hypertension, but few are treated or achieve adequate control of their blood pressure. Available and affordable medications are important for successfully controlling hypertension, but little is known about current patterns of access to, and use of, antihypertensive medications in Chinese primary health care. We used data from a nationwide cross-sectional survey (the China Patient-Centered Evaluative Assessment of Cardiac Events Million Persons Project primary health care survey), which was undertaken between November, 2016 and May, 2017, to assess the availability, cost, and prescription patterns of 62 antihypertensive medications at primary health-care sites across 31 Chinese provinces. We surveyed 203 community health centres, 401 community health stations, 284 township health centres, and 2474 village clinics to assess variation in availability, cost, and prescription by economic region and type of site. We also assessed the use of high-value medications, defined as guideline-recommended and low-cost. We also examined the association of medication cost with availability and prescription patterns. Our study sample included 3362 primary health-care sites and around 1 million people (613 638 people at 2758 rural sites and 478 393 people at 604 urban sites). Of the 3362 sites, 8·1% (95% CI 7·2-9·1) stocked no antihypertensive medications and 33·8% (32·2-35·4) stocked all four classes that were routinely used. Village clinics and sites in the western region of China had the lowest availability. Only 32·7% (32·2-33·3) of all sites stocked high-value medications, and few high-value medications were prescribed (11·2% [10·9-11·6] of all prescription records). High-cost medications were more likely to be prescribed than low-cost alternatives. China has marked deficiencies in the availability, cost, and prescription of antihypertensive medications. High-value medications are not preferentially used. Future efforts to

Participants were assigned to: low-risk group (no comorbidities, high-risk group (1+ selected comorbidities, or very high-risk group (prior hospitalization for 1+ selected comorbidities. The relationship between patient cost sharing and PDC by antihypertensive medications was assessed using standard linear regression models, controlling for risk group membership, and various demographic and clinical factors. The relationship between PDC and health care service utilization was subsequently examined using negative binomial regression models.Results: Of the 28,688 study patients, 66% were low risk. The multivariate regression model supported a relationship between patient cost sharing per 30-day fill and PDC in the following year. For every US$1.00 increase in cost sharing, PDC decreased by 1.1 days (P < 0.0001. Significant predictors of PDC included high risk, older age, gender, Charlson Comorbidity Index score, geography, and total post-index insurer- and patient-paid costs. An increase in PDC was associated with a decrease in all-cause and hypertension-related inpatient, outpatient, and emergency

    Full Text Available Objectives- To study the prescription pattern of antihypertensive drugs and analyze the medication adherence to antihypertensive drugs at rural tertiary care teaching hospital.Materials and Methods- Prospective, observational, 12 weeks, questionnaire based study, conducted in rural tertiary care teaching hospital of central India. 214 antihypertensive prescriptions were analyzed by Morisky medication adherence scale. Statistical analysis was done by MS Excel and Graph pad prism 6.0.Results- 28.03% patients were not aware about the medicines taken, 29.90% patients were unacquainted about dose and route of administration whereas 32.71% patients were unfamiliar about frequency of administration of medicines. 53.27% patients were unaware about precautions to be taken while consuming medicines.  58.68% & 12.67% patients consumed amlodipine & atenolol respectively. In 16.43% patients, atenolol + amlodipine combination therapy was prescribed.  Amongst 214 patients 12, 58 & 144 showed high, medium & low adherence respectively.  No significant difference was found on gender basis at any level of adherence.Conclusion- In this study, physicians given preference to amlodipine than other antihypertensive drugs. However, thiazide is a first line drug in stage 1 hypertension, recommended by JNC VII guideline. This indicates that there is need of creating awareness about current management of hypertension to clinicians by organizing various workshops. We observed only 5.60% patients showed high adherence to antihypertensive therapy. Therefore educational strategies must be carried out for physicians focusing on causes for nonadherence to antihypertensive medications. Also raising patient trust in their physicians may improve patient motivation to prescribed medication

    Full Text Available Abstract Background The 14-item Treatment Satisfaction Questionnaire for Medication (TSQM Version 1.4 is a reliable and valid instrument to assess patients' satisfaction with medication, providing scores on four scales – side effects, effectiveness, convenience and global satisfaction. In naturalistic studies, administering the TSQM with the side effects domain could provoke the physician to assess the presence or absence of adverse events in a way that is clinically atypical, carrying the potential to interfere with routine medical care. As a result, an abbreviated 9-item TSQM (TSQM-9, derived from the TSQM Version 1.4 but without the five items of the side effects domain was created. In this study, an interactive voice response system (IVRS-administered TSQM-9 was psychometrically evaluated among patients taking antihypertensive medication. Methods A total of 3,387 subjects were invited to participate in the study from an online panel who self-reported taking a prescribed antihypertensive medication. The subjects were asked to complete the IVRS-administered TSQM-9 at the start of the study, along with the modified Morisky scale, and again within 7 to 14 days. Standard psychometric analyses were conducted; including Cronbach's alpha, intraclass correlation coefficients, structural equation modeling, Spearman correlation coefficients and analysis of covariance (ANCOVA. Results A total of 396 subjects completed all the study procedures. Approximately 50% subjects were male with a good racial/ethnic mix: 58.3% white, 18.9% black, 17.7% Hispanic and 5.1% either Asian or other. There was evidence of construct validity of the TSQM-9 based on the structural equation modeling findings of the observed data fitting the Decisional Balance Model of Treatment Satisfaction even without the side effects domain. TSQM-9 domains had high internal consistency as evident from Cronbach's alpha values of 0.84 and greater. TSQM-9 domains also demonstrated good test

    Hypotension is common in patients undergoing surgery in the sitting position under general anesthesia, and the risk may be exacerbated by the use of antihypertensive drugs taken preoperatively. The purpose of this study was to compare hypotensive episodes in patients taking antihypertensive medications with normotensive patients during shoulder surgery in the beach chair position. Medical records of all patients undergoing shoulder arthroscopy during a 44-month period were reviewed retrospectively. The primary endpoint was the number of moderate hypotensive episodes (systolic blood pressure ≤ 85 mmHg) during the intraoperative period. Secondary endpoints included the frequency of vasopressor administration, total dose of vasopressors, and fluid administered. Values are expressed as mean (standard deviation). Of 384 patients who underwent shoulder surgery, 185 patients were taking no antihypertensive medication, and 199 were on at least one antihypertensive drug. The antihypertensive medication group had more intraoperative hypotensive episodes [1.7 (2.2) vs 1.2 (1.8); P = 0.01] and vasopressor administrations. Total dose of vasopressors and volume of fluids administered were similar between groups. The timing of the administration of angiotensin-converting enzyme inhibitors and of angiotensin receptor antagonists (≤ 10 hr vs > 10 hr before surgery) had no impact on intraoperative hypotension. Preoperative use of antihypertensive medication was associated with an increased incidence of intraoperative hypotension. Compared with normotensive patients, patients taking antihypertensive drugs preoperatively are expected to require vasopressors more often to maintain normal blood pressure.

    To explore and compare how Ghanaian, African-Surinamese (Surinamese), and White-Dutch patients perceive and manage antihypertensive drug treatment in Amsterdam, the Netherlands. Qualitative study was conducted using detailed interviews with a purposive sample of 46 hypertensive patients without comorbidity who were prescribed antihypertensives. Patients in all the ethnic groups actively decided how to manage their prescribed antihypertensive regimens. In all the groups, confidence in the doctor and beneficial effects of medication were reasons for taking prescribed antihypertensive dosage. Particularly, ethnic-minority patients reported lowering or leaving off the prescribed medication dosage. Explanations for altering prescribed dosage comprised disliking chemical medications, fear of side effects and preference for alternative treatment. Surinamese and Ghanaian men also worried about the negative effects of antihypertensives on their sexual performance. Some Ghanaians mentioned fear of addiction or lack of money as explanations for altering prescribed dosage. Surinamese and Ghanaians often discontinued medication when visiting their homeland. Some respondents from all ethnic groups preferred natural treatments although treatment type varied. Patients' explanations for their decisions regarding the use of antihypertensives are often influenced by sociocultural issues and in ethnic-minority groups also by migration-related issues. Self-alteration of prescribed medication among Surinamese and Ghanaians may contribute to the low blood pressure (BP) control rate and high rate of malignant hypertension reported among these populations in the Netherlands. This study provides new information, which can help clinicians to understand how patients of diverse ethnic populations think about managing antihypertensive drug treatment and to address ethnic disparities in medication adherence and BP control.

    Hypertension is common in deep brain stimulator (DBS) placement predisposing to intracranial hemorrhage. This retrospective review evaluates factors predicting incremental antihypertensive use intraoperatively. Medical records of Parkinson's disease (PD) patients undergoing DBS procedure between 2008-2011 were reviewed after Institutional Review Board approval. Anesthesia medication, preoperative levodopa dose, age, preoperative use of antihypertensive medications, diabetes mellitus, anxiety, motor part of the Unified Parkinson's Disease Rating Scale score and PD duration were collected. Univariate and multivariate analysis was done between each patient characteristic and the number of antihypertensive boluses. From the 136 patients included 60 were hypertensive, of whom 32 were on angiotensin converting enzyme inhibitors (ACEI) or angiotensin receptor blockers (ARB), told to hold on the morning of surgery. Antihypertensive medications were given to 130 patients intraoperatively. Age (relative risk [RR] 1.01; 95% confidence interval [CI] 1.00-1.02; p=0.005), high Joint National Committee (JNC) class (p10 years (RR 1.2; 95%CI 1.1-1.3; p=0.001) were independent predictors for antihypertensive use. No difference was noted in the mean dose of levodopa (p=0.1) and levodopa equivalent dose (p=0.4) between the low (I/II) and high severity (III/IV) JNC groups. Addition of dexmedetomidine to propofol did not influence antihypertensive boluses required (p=0.38). Intraoperative hypertension during DBS surgery is associated with higher age group, hypertensive, diabetic patients and longer duration of PD. Withholding ACEI or ARB is an independent predictor of hypertension requiring more aggressive therapy. Levodopa withdrawal and choice of anesthetic agent is not associated with higher intraoperative antihypertensive medications. Copyright © 2014 Elsevier Ltd. All rights reserved.

    Recent interest in antihypertensive agents, especially calcium channel blockers, has been sparked by the notion that these medications may be neuroprotective. A modest literature, with mixed results, has examined whether these medications might lower the odds or risk of Parkinson's disease (PD) or dementia. There are no data for essential tremor (ET). To examine the association between antihypertensive use (defined broadly and by individual subclasses) and ET, PD and dementia. For each disorder, we used cross-sectional data (association with prevalent disease) and prospective data (association with incident disease). Prospective population-based study in Spain enrolling 5,278 participants at baseline. Use of antihypertensive medications (aside from beta-blockers) was similar in prevalent ET cases and controls. Baseline use of antihypertensive agents was not associated with reduced risk of incident ET. Antihypertensive medication use was not associated with prevalent or incident PD. Calcium channel blocker use was marginally reduced in prevalent dementia cases (OR(adjusted) = 0.63, p = 0.06) but was not associated with reduced risk of incident dementia (RR(adjusted) = 1.02, p = 0.95). We did not find evidence of a protective effect of antihypertensive medications in these three neurodegenerative disorders. Copyright 2009 S. Karger AG, Basel.

    Psychosocial stress is a risk factor for hypertension and has been shown to affect response to treatment for psychiatric illnesses. We investigate the relationship between a history of social adversity experience and blood pressure control following antihypertensive medication use. A total of 1,186 participants selected from the European Prospective Investigation into Cancer-Norfolk study (531 men and 655 women, aged 42 to 80 years) had attended two health checks at which blood pressure measurements were taken; were taking antihypertensive medication at the second, but not the first health check; and had completed a questionnaire assessment of their social and psychological circumstances which included details of traumatic experiences in childhood and of adverse life events, long-term difficulties, and perceived stress in adulthood. Experience of recent loss events in adulthood was associated with a smaller reduction in systolic blood pressure after starting hypertension treatment (β = 1.78, 95 % confidence interval 0.15-3.40, per life event), independently of age, sex, preexisting health conditions, cigarette smoking history, alcohol consumption, physical activity, and obesity. Results from this study suggest that stress caused by recent losses may be associated with reduced effectiveness of treatment for hypertension. Subject to replication, these findings may help determine the specific physiological mechanisms by which medication treatment effectiveness is affected by stress.

    Antihypertensive medication and low systolic blood pressure (BP) and diastolic BP have been associated with an increased falls risk in some studies. Many older adults have indicators of frailty, which may increase their risk for falls. We contrasted the association of systolic BP, diastolic BP, number of antihypertensive medication classes taken, and indicators of frailty with risk for serious fall injuries among 5236 REGARDS study (Reasons for Geographic and Racial Difference in Stroke) participants ≥65 years taking antihypertensive medication at baseline with Medicare fee-for-service coverage. Systolic BP and diastolic BP were measured, and antihypertensive medication classes being taken assessed through a pill bottle review during a study visit. Indicators of frailty included low body mass index, cognitive impairment, depressive symptoms, exhaustion, impaired mobility, and history of falls. Serious fall injuries were defined as fall-related fractures, brain injuries, or joint dislocations using Medicare claims through December 31, 2014. Over a median of 6.4 years, 802 (15.3%) participants had a serious fall injury. The multivariable-adjusted hazard ratio for a serious fall injury among participants with 1, 2, or ≥3 indicators of frailty versus no frailty indicators was 1.18 (95% confidence interval, 0.99-1.40), 1.49 (95% confidence interval, 1.19-1.87), and 2.04 (95% confidence interval, 1.56-2.67), respectively. Systolic BP, diastolic BP, and number of antihypertensive medication classes being taken at baseline were not associated with risk for serious fall injuries after multivariable adjustment. In conclusion, indicators of frailty, but not BP or number of antihypertensive medication classes, were associated with increased risk for serious fall injuries among older adults taking antihypertensive medication. © 2017 American Heart Association, Inc.

    Full Text Available Abstract Background Many drugs are available for control of hypertension and its sequels in Nigeria but some are not affordable for majority of the populace. This serious pharmacoeconomic question has to be answered by the nation’s health economists. The objective of this study was to evaluate the cost-effectiveness of drugs from 4 classes of antihypertensive medications commonly used in Nigeria in management of hypertension without compelling indication to use a particular antihypertensive drug. Methods The study employed decision analytic modeling. Interventions were obtained from a meta-analysis. The Markov process model calculated clinical outcomes and costs during a life cycle of 30 years of 1000 hypertensive patients stratified by 3 cardiovascular risk groups, under the alternative intervention scenarios. Quality adjusted life year (QALY was used to quantify clinical outcome. The average cost of treatment for the 1000 patient was tracked over the Markov cycle model of the alternative interventions and results were presented in 2010 US Dollars. Probabilistic cost-effectiveness analysis was performed using Monte Carlo simulation, and results presented as cost-effectiveness acceptability frontiers. Expected value of perfect information (EVPI and expected value of parameter perfect information (EVPPI analyses were also conducted for the hypothetical population. Results Thiazide diuretic was the most cost-effective option across the 3 cardiovascular risk groups. Calcium channel blocker was the second best for Moderate risk and high risk with a willingness to pay of at least 2000$/QALY. The result was robust since it was insensitive to the parameters alteration. Conclusions The result of this study showed that thiazide diuretic followed by calcium channel blocker could be a feasible strategy in order to ensure that patients in Nigeria with hypertension are better controlled.

    Full Text Available Hypertension is a global health problem. Antihypertensives are the mainstay of treatment for hypertension. Some of them were accidentally found to be useful in alopecias and infantile hemangiomas and have now become standard treatment for these conditions as well. Antihypertensives are also being studied for other dermatological indications, where they have shown promising efficacy. This review focuses on the dermatological indications for antihypertensives, discussing the drugs that have been tried, as well as their efficacy, dosage, duration of therapy, and adverse effects.

    Full Text Available Abstract Background Antihypertensive medications are widely prescribed by doctors and heavily promoted by the pharmaceutical industry. Despite strong evidence of the effectiveness and cost-effectiveness of thiazide diuretics, trends in both promotion and prescription of antihypertensive drugs favour newer, less cost-effective agents. Observational evidence shows correlations between exposure to pharmaceutical promotion and less ideal prescribing. Our study therefore aimed to determine whether print advertisements for antihypertensive medications promote quality prescribing in hypertension. Methods We performed a cross-sectional study of 113 advertisements for antihypertensive drugs from 4 general practice-oriented Australian medical publications in 2004. Advertisements were evaluated using a quality checklist based on a review of hypertension management guidelines. Main outcome measures included: frequency with which antihypertensive classes were advertised, promotion of thiazide class drugs as first line agents, use of statistical claims in advertisements, mention of harms and prices in the advertisements, promotion of assessment and treatment of cardiovascular risk, promotion of lifestyle modification, and targeting of particular patient subgroups. Results Thiazides were the most frequently advertised drug class (48.7% of advertisements, but were largely promoted in combination preparations. The only thiazide advertised as a single agent was the most expensive, indapamide. No advertisement specifically promoted any thiazide as a better first-line drug. Statistics in the advertisements tended to be expressed in relative rather than absolute terms. Drug costs were often reported, but without cost comparisons between drugs. Adverse effects were usually reported but largely confined to the advertisements' small print. Other than mentioning drug interactions with alcohol and salt, no advertisements promoted lifestyle modification. Few

    Full Text Available Pharmacy benefit management (PBM programs provide attractive discounts for drug purchase, a relevant measure to address costs, mainly of drugs for the treatment of chronic diseases. This study investigated whether PBM may be used as a tool to provide information about the use of antihypertensive medications when they are purchased. The profile of medicines taken to treat high blood pressure by large IT company employees and their dependents was evaluated from January to December 2009. The mean rate of drug boxes purchased to control hypertension was 9.4 ± 10.0 in 2009. Men purchased more drugs than women. The number of drugs purchased for the treatment of hypertension was lower than expected in all age groups except for individuals aged 54-58 and >59 years. Among men, the purchase of drugs to treat hypertension was higher than expected in the 24-28, 34-38 and 54-58 age groups. Among women, results matched expectations, except for the age group 34-38 years, in which purchase was lower than expected. Individuals in the age group 0-18 years were found to consume antihypertensive drugs. Although the PBM system may be used to identify drugs purchased by users, it does not ensure patient adherence to recommended drug treatment to control hypertension.O objetivo do Programa de Benefícios em Medicamentos (PBM é proporcionar descontos atraentes para aquisição de medicamentos, um fator relevante para o custo, principalmente no tratamento de doenças crônicas.

    Over the past decade, interest has risen in fermented dairy foods that promote health and could prevent diseases such as hypertension. This biological effect has mainly been attributed to bioactive peptides encrypted within dairy proteins that can be released during fermentation with specific lactic acid bacteria or during gastrointestinal digestion. The most studied bioactive peptides derived from dairy proteins are antihypertensive peptides; however, a need exists to review the different studies dealing with the evaluation of antihypertensive fermented milk before a health claim may be associated with the product. Thus, the objective of this overview was to present available information related to the evaluation of fermented milk containing antihypertensive peptides by in vitro and in vivo studies, which are required before a fermented functional dairy product may be introduced to the market. Although commercial fermented milks with antihypertensive effects exist, these are scarce and most are based on Lactobacillus helveticus. Thus, a great opportunity is available for the development of functional dairy products with new lactic acid bacteria that support heart health through blood pressure- and heart rate-lowering effects. Hence, the consumer may be willing to pay a premium for foods with important functional benefits. Copyright © 2016 American Dairy Science Association. Published by Elsevier Inc. All rights reserved.

  5. Resistant and Refractory Hypertension: Antihypertensive Treatment Resistance vs Treatment Failure

    2017-01-01

    Resistant or difficult to treat hypertension is defined as high blood pressure that remains uncontrolled with 3 or more different antihypertensive medications, including a diuretic. Recent definitions also include controlled blood pressure with use of 4 or more medications as also being resistant to treatment. Recently, refractory hypertension, an extreme phenotype of antihypertensive treatment failure has been defined as hypertension uncontrolled with use of 5 or more antihypertensive agents, including a long-acting thiazide diuretic and a mineralocorticoid receptor antagonist. Patients with resistant vs refractory hypertension share similar characteristics and comorbidities, including obesity, African American race, female sex, diabetes, coronary heart disease, chronic kidney disease, and obstructive sleep apnea. Patients with refractory vs resistant hypertension tend to be younger and are more likely to have been diagnosed with congestive heart failure. Refractory hypertension might also differ from resistant hypertension in terms of underlying cause. Preliminary evidence suggests that refractory hypertension is more likely to be neurogenic in etiology (ie, heightened sympathetic tone), vs a volume-dependent hypertension that is more characteristic of resistant hypertension in general.

    Full Text Available Hypertension is a major risk factor for a spectrum of cardiovascular diseases (CVD, including myocardial infarction, sudden death, and stroke. In the US, over 65 million people have high blood pressure and a large proportion of these individuals are prescribed antihypertensive medications. Although large long-term clinical trials conducted in the last several decades have identified a number of effective antihypertensive treatments that reduce the risk of future clinical complications, responses to therapy and protection from cardiovascular events vary among individuals.Using a genome-wide association study among 21,267 participants with pharmaceutically treated hypertension, we explored the hypothesis that genetic variants might influence or modify the effectiveness of common antihypertensive therapies on the risk of major cardiovascular outcomes. The classes of drug treatments included angiotensin-converting enzyme inhibitors, beta-blockers, calcium channel blockers, and diuretics. In the setting of the Cohorts for Heart and Aging Research in Genomic Epidemiology (CHARGE consortium, each study performed array-based genome-wide genotyping, imputed to HapMap Phase II reference panels, and used additive genetic models in proportional hazards or logistic regression models to evaluate drug-gene interactions for each of four therapeutic drug classes. We used meta-analysis to combine study-specific interaction estimates for approximately 2 million single nucleotide polymorphisms (SNPs in a discovery analysis among 15,375 European Ancestry participants (3,527 CVD cases with targeted follow-up in a case-only study of 1,751 European Ancestry GenHAT participants as well as among 4,141 African-Americans (1,267 CVD cases.Although drug-SNP interactions were biologically plausible, exposures and outcomes were well measured, and power was sufficient to detect modest interactions, we did not identify any statistically significant interactions from the four

    Full Text Available Background. In the treatment of chronic, especially asymptomatic pathology one of the main problem is the adherence to therapy. Patients with arterial hypertension need long-term, often lifelong medication, and how strictly they adhere to prescriptions often determines the course of the disease and the medical measures effectiveness. According to statistics, more than half of patients with hypertension are characterized by low compliance, which leads to complications of this disease. The objective of the research is to identify and analize the individual psychological factors that determine patient adherence to antihypertensive therapy. Methods and materials. This study was conducted during 2011-2013 at the cardiology departments of the Kyiv Alexander Hospital, polyclinics number 2 Shevchenko district in Kyiv, Desnyanskiy clinic №3 district in Kyiv, medical center "Adonis plus". We examined 203 patients with arterial hypertension (average age 53,5 ± 4,5 years. Methods: socio-demographic, clinical, clinical and psychological, psychodiagnostical, mathematical and statistical methods. Psychodiagnostical method included: 8-item Morisky medical adherence scale (Morisky D. E., 2008; self-assessment anxiety scale Charles D. Spielberger – Y.L Hanin (A.V. Batarshev, 2005; the Minnesota Multiphasic Personality Inventory questionnaire (MMRI (F.B. Berezin, 1994; "The level of subjective control" (A.A. Rean, 2001; "Index of attitudes to health" (S.D.

However, little is known about whether this association differs by comorbid medical condition or whether reasons for nonadherence differ by depressive symptoms or comorbid medical condition. Methods: Self-reported extent of nonadherence, reasons for nonadherence, and depressive symptoms among 1,026 veterans prescribed medications for hypertension, dyslipidemia, and/or type 2 diabetes were assessed. Results: In multivariable logistic regression adjusted for clinical and demographic factors, the odds of nonadherence were higher among participants with high depressive symptom burden for dyslipidemia (n=848; odds ratio [OR]: 1.42, P=0.03 but not hypertension (n=916; OR: 1.24, P=0.15, or type 2 diabetes (n=447; OR: 1.15, P=0.51. Among participants reporting nonadherence to antihypertensive and antilipemic medications, those with greater depressive symptom burden had greater odds of endorsing medication nonadherence reasons related to negative expectations and excessive economic burden. Neither extent of nonadherence nor reasons for nonadherence differed by depressive symptom burden among patients with diabetes. Conclusion: These findings suggest that clinicians may consider tailoring interventions to improve adherence to antihypertensive and antilipemic medications to specific medication concerns of participants with depressive symptoms

    Full Text Available Hypertension is one of the major chronic diseases with high mortality and morbidity in the today’s world. Present study was to assess the prescribing pattern of antihypertensive medications in geriatric population suffering mainly from hypertension with or without co morbidities like Diabetes Mellitus (DM. A prospective observational study was carried out for a period of six months in an in-patient general medicine department. Elderly patients who have been diagnosed with pure hypertension as per JNC 7 guidelines and hypertension with co- morbid condition like diabetes mellitus and patients receiving or prescribed with antihypertensive drugs were included. A total of 150 prescriptions were analyzed. The present study revealed that there were 93 patients with pure Hypertension and 57 patients with co morbid conditions like Diabetes Mellitus (DM. Among antihypertensive drugs in pure hypertensive cases, 53.76% of cases were prescribed with monotherapy, followed by 46.23% by combination therapy. The commonly prescribed antihypertensive monotherapy is calcium channel blockers. The most commonly prescribed combination therapy in severe cases was angiotensin receptor blockers with diuretics. This prescribing pattern of antihypertensives was as per Joint National Committee-7report on hypertension. In case of geriatric patients suffering from hypertension with Type 2 diabetes mellitus, most commonly prescribed antihypertensive as monotherapy was found to be amlodipine and combination therapy was telmisartan + hydrochlorothiazide.

Certain antihypertensives may influence progression of chronic liver disease. Therefore, the aim of this study is to investigate the impact of the commonly used antihypertensives amlodipine, captopril, furosemide, metoprolol, propranolol, and spironolactone on alcohol-induced damage toward human hepatocytes (hHeps.Methods: hHeps were isolated by collagenase perfusion. Reactive oxygen species (ROS were measured by fluorescence-based assays. Cellular damage was determined by lactate-dehydrogenase (LDH-leakage. Expression analysis was performed by reverse-transcription polymerase chain reaction and Western blot. Transforming growth factor (TGF-β signaling was investigated by a Smad3/4-responsive luciferase-reporter assay.Results: Ethanol and TGF-β1 rapidly increased ROS in hHeps, causing a release of 40%–60% of total LDH after 72 hours. All antihypertensives dose dependently reduced ethanol-mediated oxidative stress and cellular damage. Similar results were observed for TGF-β1-dependent

    In the EMPA-REG BP trial, empagliflozin 10 mg and 25 mg once daily reduced glycohemoglobin, blood pressure (BP), and weight versus placebo in patients with type 2 diabetes mellitus and hypertension. Patients received placebo (n=271), empagliflozin 10 mg (n=276), or empagliflozin 25 mg (n=276) for 12 weeks (n=full analysis set). This present analysis investigated changes from baseline to week 12 in mean 24-hour systolic BP (SBP) and diastolic BP (DBP) in patients receiving 0, 1, or ≥2 antihypertensive medications and patients receiving/not receiving diuretics or angiotensin-converting enzyme inhibitors/angiotensin receptor blockers. Compared with placebo, empagliflozin 10 mg and 25 mg reduced mean 24-hour SBP/DBP in patients receiving 0 (10 mg: -3.89/-2.58 mm Hg; 25 mg: -3.77/-2.45 mm Hg), 1 (10 mg: -4.74/-1.97 mm Hg; 25 mg: -4.27/-1.81 mm Hg), or ≥2 (10 mg: -2.36/-0.68 mm Hg; 25 mg: -4.17/-1.54 mm Hg) antihypertensives. The effect of empagliflozin was not significantly different between subgroups by number of antihypertensives for changes in SBP (interaction P value 0.448) or DBP (interaction P value 0.498). Empagliflozin reduced 24-hour mean SBP/DBP irrespective of diuretic or angiotensin-converting enzyme inhibitor/angiotensin receptor blocker use, with no significant difference between subgroups by use/no use of diuretics (interaction P values 0.380 [systolic]; 0.240 [diastolic]) or angiotensin-converting enzyme inhibitors/angiotensin receptor blockers (interaction P values 0.900 [systolic]; 0.359 [diastolic]). In conclusion, in patients with type 2 diabetes mellitus and hypertension, empagliflozin for 12 weeks reduced SBP and DBP versus placebo, irrespective of the number of antihypertensives and use of diuretics or angiotensin-converting enzyme inhibitors/angiotensin receptor blockers.

    1990-12-01

    A longitudinal study of 34 198 non-Hispanic white California Seventh-day Adventists identified incident cases of renal carcinoma over six years of follow-up. The use of antihypertensive medications and self-reported hypertension had estimated age-sex adjusted incidence rate ratios of 4.51 and 2.90 respectively. These were relatively unchanged by stratifying on additional variables that may have been confounders. Cases diagnosed later during the follow-up period had the strongest association with hypertension, making the alternative explanation that the cancer may have caused the hypertension less likely. Being married in 1976 (amongst females at least) was also associated with a marked elevation of risk. Point estimates of effect suggested that frequent (greater than or equal to 3 week) consumption of fruit (RR = 0.21) and salad vegetables (RR = 0.34) may be protective for this cancer, although the 95% confidence interval did not quite exclude the null value.

A recent study reported that the administration of astaxanthin induced a significant reduction in blood pressure and delayed the incidence of stroke in stroke-prone spontaneously hypertensive rats, suggesting that astaxanthin also has antihypertensive effect. In a study using aortic rings of spontaneously hypertensive rats, astaxanthin induced a significant reduction of the contractile responses of the aorta to α-adrenergic receptor agonist and angiotensin II, which may contribute to the antihypertensive effect of astaxanthin. In a histopathological study, astaxanthin decreased coronary artery wall thickness compared with the control, indicating the possibility that astaxanthin ameliorates hypertension-induced vascular remodeling. Astaxanthin has anti-inflammatory, antidiabetic, antihypertensive, and antioxidative activities; therefore, we should perform further studies to elucidate an antiatherogenic effect of astaxanthin.Keywords: astaxanthin, antioxidant, antihypertensive effect, atherosclerosis

    1998-06-01

    Two problems in the treatment of hypertension continue to be largely unsolved. The first, and more simple, is our inability to adequately control blood pressure in the majority of hypertensive patients. This not only reflects the difficulty of retaining patients in effective treatment programs, but also of convincing physicians to strive for optimal blood pressure levels. There is a continuing need for new antihypertensive drugs and combinations to help accomplish these goals. The second major problem is that the major clinical endpoints, including coronary events and renal failure, have not been adequately reduced by traditional therapies. Standard regimens, particularly those including diuretics, have protected against strokes and heart failure. Our improved understanding of vascular biology in hypertension has directed interest to the mechanisms in hypertensive patients that might accelerate atherosclerosis and vascular events in these individuals. This involves addressing the concomitant metabolic risk factors that comprise the "Hypertension Syndrome," and, perhaps of equal importance, finding therapies that directly inhibit unwanted types of growth and proliferative activities within the walls of critical arteries. Many substances within the endothelium and the vascular wall may participate as initiators or mediators of pathology, but most information thus far has focused on the renin-angiotensin system. Angiotensin converting enzyme inhibitors (and potentially angiotensin receptor blockers) have provided coronary and renal protection in various cardiovascular conditions, though not yet in formal hypertension trials. Calcium channel blockers have also shown promise, including recent stroke and cardiovascular benefits in patients with isolated systolic hypertension, but, again, definitive coronary data in hypertension are awaited. Unless concomitant conditions mandate the selection of a particular antihypertensive drug class, physicians currently have a dilemma

    Poor patient adherence is often the reason for suboptimal blood pressure control. Electronic monitoring is one method of assessing adherence. The aim was to systematically review the literature on electronic monitoring of patient adherence to self-administered oral antihypertensive medications. We searched the Pubmed, Embase, Cinahl and Psychinfo databases and websites of suppliers of electronic monitoring devices. The quality of the studies was assessed according to the quality criteria proposed by Haynes et al. Sixty-two articles were included; three met the criteria proposed by Haynes et al. and nine reported the use of electronic adherence monitoring for feedback interventions. Adherence rates were generally high, whereas average study quality was low with a recent tendency towards improved quality. One study detected investigator fraud based on electronic monitoring data. Use of electronic monitoring of patient adherence according to the quality criteria proposed by Haynes et al. has been rather limited during the past two decades. Electronic monitoring has mainly been used as a measurement tool, but it seems to have the potential to significantly improve blood pressure control as well and should be used more widely.

    Renal sympathetic activation plays a key role in the pathogenesis of hypertension, as demonstrated by high renal norepinephrine spillover into plasma of patients with essential hypertension. Renal denervation has demonstrated a significant reduction in blood pressure in unblinded studies of hypertensive patients. The SYMPLICITY HTN-3 trial, the first prospective, masked, randomized study of renal denervation versus sham control, failed its primary efficacy end point and raised important questions around potentially confounding factors, such as drug changes and adherence, study population, and procedural methods. The SPYRAL HTN Global Clinical Trial Program is designed to address limitations associated with predicate studies and provide insight into the impact of pharmacotherapy on renal denervation efficacy. The 2 initial trials of the program focus on the effect of renal denervation using the Symplicity Spyral multielectrode renal denervation catheter in hypertensive patients in the absence (SPYRAL HTN OFF-MED) and presence (SPYRAL HTN ON-MED) of antihypertensive medications. The SPYRAL HTN ON-MED study requires patients to be treated with a consistent triple therapy antihypertensive regimen, whereas the SPYRAL HTN OFF-MED study includes a 3- to 4-week drug washout period followed by a 3-month efficacy and safety end point in the absence of antihypertensive medications. The studies will randomize patients with combined systolic-diastolic hypertension to renal denervation or sham procedure. Both studies allow renal denervation treatments in renal artery branches and accessories. These studies will inform the design of the second pivotal phase of the program, which will more definitively analyze the antihypertensive effect of renal denervation. Copyright © 2015 Elsevier Inc.

    Advanced dementia is characterized by severe cognitive impairment and complete functional dependence. Patients' goals of care should guide the prescribing of medication during such terminal illness. Medications that do not promote the primary goal of care should be minimized. To estimate the prevalence of medications with questionable benefit used by nursing home residents with advanced dementia, identify resident- and facility-level characteristics associated with such use, and estimate associated medication expenditures. Cross-sectional study of medication use by nursing home residents with advanced dementia using a nationwide long-term care pharmacy database linked to the Minimum Data Set (460 facilities) between October 1, 2009, and September 30, 2010. Use of medication deemed of questionable benefit in advanced dementia based on previously published criteria and mean 90-day expenditures attributable to these medications per resident. Generalized estimating equations using the logit link function were used to identify resident- and facility-related factors independently associated with the likelihood of receiving medications of questionable benefit after accounting for clustering within nursing homes. Of 5406 nursing home residents with advanced dementia, 2911 (53.9%) received at least 1 medication with questionable benefit (range, 44.7% in the Mid-Atlantic census region to 65.0% in the West South Central census region). Cholinesterase inhibitors (36.4%), memantine hydrochloride (25.2%), and lipid-lowering agents (22.4%) were the most commonly prescribed. In adjusted analyses, having eating problems (adjusted odds ratio [AOR], 0.68; 95% CI, 0.59-0.78), a feeding tube (AOR, 0.58; 95% CI, 0.48-0.70), or a do-not-resuscitate order (AOR, 0.65; 95% CI, 0.57-0.75), and enrolling in hospice (AOR, 0.69; 95% CI, 0.58-0.82) lowered the likelihood of receiving these medications. High facility-level use of feeding tubes increased the likelihood of receiving these

    Full Text Available Abstract Background The identification of poor medicinal adherence is difficult because direct observation of medication use is usually impractical. Up to 50% of individuals on chronic therapies may not be taking their medication as prescribed. This study is one of the first to explore possible risk factors for over-reporting of antihypertensive adherence using electronic medication monitoring. Methods The adherence of 286 individuals on single-drug antihypertensive therapy in a large managed care organization was electronically monitored for approximately three months. Questionnaires on socioeconomic background, adherence to therapy, health beliefs, and social support before and after adherence monitoring were completed. Over-reporting of antihypertensive adherence was assessed by comparing the self-reported frequency of noncompliance with that determined from electronic dosing records. Risk factors for over-reporting were identified by contingency table analysis and step-wise logistic regression. Results Although only 21% of participants acknowledged missing doses on one or more days per week, electronic monitoring documented nonadherence at this or a higher level in 42% of participants. The following variables were associated with over-reporting: >1 versus 1 daily dose (OR = 2.58; 95% CI = 1.50–4.41; p = .0006, lower perceived health risk from nonadherence (OR = 1.35; 95% CI = 1.10–1.64; p = .0035, and annual household income of $30,000 (OR = 2.64; 95% CI = 1.13–6.18; p = .025. Conclusions Over-reporting of adherence may be affected by factors related to dosing frequency, health beliefs and socioeconomic status. This topic deserves further investigation in other patient populations to elucidate possible underlying behavioral explanations.

  7. Home blood pressure monitoring and self-titration of antihypertensive medications: Proposed patient selection criteria.

    Hill, James R

    2016-05-01

    Recent studies have demonstrated that home blood pressure monitoring (HBPM), coupled with self-titration of medications is a viable intervention to control hypertension. There are currently no established criteria to evaluate patients for inclusion in such a program. The purpose of this discussion is to propose criteria for determining if a patient is appropriate to participate in a program of HBPM and self-titration. Inclusion criteria for two self-titration trials were examined, and additional factors in clinical practice were identified and discussed. Additional selection criteria were proposed to support the decision to enroll a patient in an antihypertensive self-titration program. Inclusion criteria from self-titration trials provide a reasonable starting point for choosing appropriate patients in clinical practice, but additional research is necessary. Adaptation of these criteria and consideration of the identified factors can be used to develop decision support instruments. Such instruments should be evaluated for effectiveness and reliability prior to use in clinical practice. HBPM combined with self-titration is an effective patient-centered approach for hypertension management. Decision support instruments to determine appropriate patients are necessary for safe and effective use in clinical practice. ©2015 American Association of Nurse Practitioners.

    Full Text Available Abstract Background Antihypertensive drug choices and treatment levels are not in accordance with the existing guidelines. We aimed to assess the impact of a guideline implementation intervention on antihypertensive drug prescribing. Methods In this controlled before and after study, the effects of a multifaceted (education, audit and feedback, local care pathway quality programme was evaluated. The intervention was carried out in a health centre between 2002 and 2003. From each health care unit (n = 31, a doctor-nurse pair was trained to act as peer facilitators in the intervention. All antihypertensive drugs prescribed by 25 facilitator general practitioners (intervention GPs and 53 control GPs were retrieved from the nationwide Prescription Register for three-month periods in 2001 and 2003. The proportions of patients receiving specific antihypertensive drugs and multiple antihypertensive drugs were measured before and after the intervention for three subgroups of hypertension patients: hypertension only, with coronary heart disease, and with diabetes. Results In all subgroups, the use of multiple concurrent medications increased. For intervention patients with hypertension only, the odds ratio (OR was 1.12 (95% CI 0.99, 1.25; p = 0.06 and for controls 1.13 (1.05, 1.21; p = 0.002. We observed no statistically significant differences in the change in the prescribing of specific antihypertensive agents between the intervention and control groups. The use of agents acting on the renin-angiotensin-aldosterone system increased in all subgroups (hypertension only intervention patients OR 1.19 (1.06, 1.34; p = 0.004 and controls OR 1.24 (1.15, 1.34; p Conclusions A multifaceted guideline implementation intervention does not necessarily lead to significant changes in prescribing performance. Rigorous planning of the interventions and quality projects and their evaluation are essential.

    Hypertension and diabetes mellitus are common comorbidities of colorectal cancer. We designed a prospective cohort study aiming to investigate the impact of long-term antihypertensive and antidiabetic medications on colorectal cancer-specific survival and recurrence among 713 post-surgical patients. All participants received radical resection for colorectal cancer during 2000-08, and they were followed up until July 2017. Colorectal cancer patients without hypertension had better survival than those with hypertension (median survival time [MST]: 190.3 months versus 99.0 months, p colorectal cancer survival was statistically significant, that is, patients receiving antidiabetic medications had longer survival time than untreated diabetic patients (MST: 135.8 months versus 80.2 months, p : 0.007), whereas the prognosis was greatly improved in colorectal cancer patients without diabetes mellitus ( p colorectal cancer relative to those without medications, respectively. Our data indicate that long-term antidiabetic medications can significantly prolong the survival and improve the prognosis of post-surgical colorectal cancer.

    The putative antihypertensive effect of milk after fermentation by lactic bacteria has attracted attention over the past 20 years. Research on fermented milk and hypertension has mainly focused on the content of peptides with in-vitro angiotensin converting enzyme-inhibitor effect. However......, fermented milk products contain several proteins, peptides and minerals, all with possible different antihypertensive modes of actions. The burden of cardiovascular events in industrialized countries caused by hypertension is considerable. Diet modifications are one way to lower blood pressure......, and fermented milk could be a feasible way. In this review, interventional human studies of the possible antihypertensive effect of fermented milk are evaluated. The results are diverging, and the antihypertensive effect is still debatable.

    Self-reported medication adherence is known to overestimate true adherence. However, little is known about patient factors that may contribute to the upward bias in self-reported medication adherence. The objective of this study is to examine whether demographic, behavioral, medication and mood factors are associated with being a false-positive self-reported adherer (FPA) to antihypertensive drug treatment. We studied 175 patients (mean age: 50 years; 57% men) from primary-care clinics starting antihypertensive drug treatment. Self-reported adherence (SRA) was measured with the Medication Adherence Report Scale (MARS) and by the number of drug doses missed in the previous week/month, and compared with pill count adherence ratio (PCAR) as gold standard. Data on adherence, demographic, behavioral, medication and mood factors were collected at baseline and every 3 months up to 1 year. FPA was defined as being a non-adherer by PCAR and an adherer by self-report. Mixed effect logistic regression was used for the analysis. Twenty percent of participants were FPA. Anxiety increased (odds ratio (OR): 3.00; P=0.01), whereas smoking (OR: 0.40; P=0.03) and drug side effects (OR: 0.46, P=0.03) decreased the probability for FPA by MARS. Education below high-school completion increased the probability of being an FPA as measured by missing doses in the last month (OR: 1.66; P=0.04) and last week (OR: 1.88; P=0.02). The validity of SRA varies significantly according to drug side effects, behavioral factors and patient's mood. Careful consideration should be given to the use of self-reported measures of adherence among patients likely to be false-positive adherers.

    The aim of this study is to determine and compare the proximate composition, the degree of hydrolysis (DH) and the antihypertensive activity of edible bird's nest (EBN) hydrolysates of two different drying methods. Four types of enzymes (alcalase, bromelain, pancreatin and papain) were used in this study and with different hydrolysis time (30, 60, 90, 120, 180 and 240 min). The highest DH for alcalase (79.48 - 84.09%), pancreatine (77.10 - 80.45%) and papain (82.33%) for EBN hydrolysates was produced with alcalase treatment at 60 - 90 min, pancreatine treatment at 30 - 90 min and papain treatment at 90 min. Bromelain generated hydrolysates showed low DH. EBN hydrolysed using alcalase, pancreatin and papain have significantly higher protein content compared to raw EBN and the moisture content of all hydrolysates treatments was significantly lower compared to raw EBN. For antihypertensive assay, freeze dried EBN hydrolysates have higher antihypertensive activity compared to spray dried hydrolysates. The highest antihypertensive activity for freeze dried samples was produced by alcalase, bromelain and pancreatin and in the range of 80.22 - 86.97%. Meanwhile, papain proved to be less effective in producing hydrolysate with antihypertensive ability. In conclusion, EBN hydrolysate prepared by alcalase, bromelain and pancreatin could be classified as a functional food as it showed significant antihypertensive activity.

    2010-03-01

    Full Text Available Introduction: Chronic diseases substantially contribute to the continuous increase in health care expenditures, including type-2 diabetes mellitus as one of the most expensive chronic diseases. Arterial hypertension presents a risk factor for the development of type-2 diabetes mellitus. Numerous analyses have demonstrated that antihypertensive therapies promote the development of type-2-diabetes mellitus. Studies indicate, that the application of angiotensin converting enzyme (ACE inhibitors and angiotensin-receptor-blockers (ARB lead to less new-onset diabetes compared to beta-blockers, diuretics and placebo. Given that beta-blockers and diuretics impair the glucose metabolism, the metabolic effects of different antihypertensive drugs should be regarded; otherwise not only the disease itself, but also antihypertensive therapies may promote the development of new-onset diabetes. Even though, the cost of ACE inhibitors and ARB are higher, the use in patients with metabolic disorders could be cost-effective in the long-term if new-onset diabetes is avoided. Objectives: To evaluate which class of antihypertensive agents promote the development or the manifestation of type-2 diabetes mellitus. How high is the incidence of new-onset diabetes during antihypertensive therapy and how is treatment-induced type-2 diabetes mellitus evaluated clinically? Which agents are therefore cost-effective in the long term? Which ethical, social or legal aspects should be regarded?MethodsA systematic literature review was conducted including clinical trials with at least ten participants which reported new-onset diabetes in the course of antihypertensive treatment. The trials had to be published after 1966 (after 2003 for economic publications in English or German. Results: A total of 34 clinical publications meet the inclusion criteria. Of these, eight publications focus on the development of diabetes mellitus under treatment with diuretic and/or beta-blockers, six

    We studied the effect of early antihypertensive treatment on death, major disability, and vascular events among patients with acute ischemic stroke according to their baseline SBP. We randomly assigned 4071 acute ischemic stroke patients with SBP between 140 and less than 220 mmHg to receive antihypertensive treatment or to discontinue all antihypertensive medications during hospitalization. A composite primary outcome of death and major disability and secondary outcomes were compared between treatment and control stratified by baseline SBP levels of less than 160, 160-179, and at least 180 mmHg. At 24 h after randomization, differences in SBP reductions were 8.8, 8.6 and 7.8 mmHg between the antihypertensive treatment and control groups among patients with baseline SBP less than 160, 160-179, and at least 180 mmHg, respectively (P baseline SBP subgroups on death (P = 0.02): odds ratio (95% CI) of 2.42 (0.74-7.89) in patients with baseline SBP less than 60 mmHg and 0.34 (0.11-1.09) in those with baseline SBP at least 180 mmHg. At the 3-month follow-up, the primary and secondary clinical outcomes were not significantly different between the treatment and control groups by baseline SBP levels. Early antihypertensive treatment had a neutral effect on clinical outcomes among acute ischemic stroke patients with various baseline SBP levels. Future clinical trials are warranted to test BP-lowering effects in acute ischemic stroke patients by baseline SBP levels. ClinicalTrials.gov Identifier: NCT01840072.

    Hypertension is often treated pharmacologically, yet adherence is poor. Beliefs about antihypertensive medicine, i.e., the necessity-concern framework (NCF), are valuable for explaining adherence. Therefore, a model structure is transferred from hypercholesterolemia to hypertension, assuming a mediating role of the NCF. Patients with hypertension (n=273) were surveyed online about demographics, health- and treatment-related factors, control beliefs, necessity and concern beliefs about their medication, and adherence. The data were analyzed using structural equation modeling (SEM). Necessity was positively (β=0.26, p=0.009) and concern was negatively (β=-0.51, p=0.020) associated with adherence. The NCF mediated the influence of background variables on adherence. Necessity was associated with comorbidity (β=-0.36, pConcern was associated with side effects (β=0.38, pconcern framework as a mediating factor was confirmed in hypertension, explaining more variance than previous approaches (23%). A personalized, emotionally supportive doctor-patient communication could be key to addressing beliefs about medicine and therefore to increasing adherence. Copyright © 2017 Elsevier B.V.

  19. Clinical Trials of Blood Pressure Lowering and Antihypertensive Medication: is Cognitive Measurement State-Of-The-Art?

    Elias, Merrill F; Torres, Rachael V; Davey, Adam

    2018-02-22

    Randomized controlled trials of blood pressure (BP) lowering and antihypertensive medication use on cognitive outcomes have often been disappointing, reporting mixed findings and small effect sizes. We evaluate the extent to which cognitive assessment protocols used in these trials approach state-of-the-art. Overall, we find that a primary focus on cognition and the systematic selection of cognitive outcomes across trials take a backseat to other trial goals. Twelve trials investigating change in cognitive functioning were examined and none met criteria for state-of-the-art assessment, including use of at least 4 tests indexing 2 cognitive domains. Four trials investigating incident dementia were also examined. Each trial used state-of-the-art diagnostic criteria to assess dementia, although follow-up periods were relatively short, with only 2 trials lasting for at least 3 years. Weaknesses in each trial may act to obscure or weaken the positive effects of BP lowering on cognitive functioning. Improving trial designs in terms of cognitive outcomes selected and length of follow-up periods employed could lead to more promising findings. We offer logical steps to achieve state-of-the-art assessment protocols, with examples, in hopes of improving future trials.

    Diabetic retinopathy (DR) is a leading cause of blindness and common complication of diabetes. Many diabetic patients take antihypertensive drugs to prevent cardiovascular problems, but these drugs may have unintended consequences on eyesight. Six common classes of antihypertensive drug are angiotensin converting enzyme (ACE) inhibitors, alpha blockers, angiotensin receptor blockers (ARBs), -blockers, calcium channel blockers, and diuretics. Analysis of medical history data might indicate which of these drugs provide safe blood pressure control, and a literature review is often used to guide such analyses. Beyond manual reading of relevant publications, we sought to identify quantitative trends in literature from the biomedical database PubMed to compare with quantitative trends in the clinical data. By recording and analyzing PubMed search results, we found wide variation in the prevalence of each antihypertensive drug in DR literature. Drug classes developed more recently such as ACE inhibitors and ARBs were most prevalent. We also identified instances of change-over-time in publication patterns. We then compared these literature trends to a dataset of 500 diabetic patients from the UT Hamilton Eye Institute. Data for each patient included class of antihypertensive drug, presence and severity of DR. Graphical comparison revealed that older drug classes such as diuretics, calcium channel blockers, and -blockers were much more prevalent in the clinical data than in the DR and antihypertensive literature. Finally, quantitative analysis of the dataset revealed that patients taking -blockers were statistically more likely to have DR than patients taking other medications, controlling for presence of hypertension and year of diabetes onset. This finding was concerning given the prevalence of -blockers in the clinical data. We determined that clinical use of -blockers should be minimized in diabetic patients to prevent retinal damage.

    Background Low adherence to pharmacological treatments is one of the factors associated with poor blood pressure control. Questionnaires are an indirect measurement method that is both economic and easy to use. However, questionnaires should meet specific criteria, to minimize error and ensure reproducibility of results. Numerous studies have been conducted to design questionnaires that quantify adherence to pharmacological antihypertensive treatments. Nevertheless, it is unknown whether questionnaires fulfil the minimum requirements of validity and reliability. The aim of this study was to compile validated questionnaires measuring adherence to pharmacological antihypertensive treatments that had at least one measure of validity and one measure of reliability. Methods A literature search was undertaken in PubMed, the Excerpta Medica Database (EMBASE), and the Latin American and Caribbean Health Sciences Literature database (Literatura Latino-Americana e do Caribe em Ciências da Saúde [LILACS]). References from included articles were hand-searched. The included papers were all that were published in English, French, Portuguese, and Spanish from the beginning of the database’s indexing until July 8, 2013, where a validation of a questionnaire (at least one demonstration of the validity and at least one of reliability) was performed to measure adherence to antihypertensive pharmacological treatments. Results A total of 234 potential papers were identified in the electronic database search; of these, 12 met the eligibility criteria. Within these 12 papers, six questionnaires were validated: the Morisky–Green–Levine; Brief Medication Questionnaire; Hill-Bone Compliance to High Blood Pressure Therapy Scale; Morisky Medication Adherence Scale; Treatment Adherence Questionnaire for Patients with Hypertension (TAQPH); and Martín–Bayarre–Grau. Questionnaire length ranged from four to 28 items. Internal consistency, assessed by Cronbach’s α, varied from 0

    The diuretics are essential medicaments of antihypertensive therapy. They reduce blood pressure and cardiovascular events optimally. With increasing doses of thiazides and thiazide analogs do not come further powerful effect of reducing blood pressure or cardiovascular mortality and morbidity, but clearly elevate the side effects. Because of it, the minimum effective dose level and the fixed-dose combination therapy should be preferred. The use these drugs leads to especially positive outcome in elder patients, isolated systolic hypertension, heart failure, after stroke and in black population. Loop diuretics as antihypertensive therapy can be used only by renal impairment. The use of aldosterone antagonists can have a good effect not only on heart failure but also on prevention of atrial fibrillation. Furthermore, using it in a combination therapy with thiazides, it reduces the risk of hypokalemia. Therefore, the diuretic treatment in hypertension is flourishing again. Orv.

    Compliance to antihypertensive therapy reduces the risk of complications. It is important to understand the factors affecting compliance in patients so that the goal of successful treatment is not jeopardized. To determine the proportion of participants' compliant to treatment and various factors associated with compliance of antihypertensive treatment. A cross-sectional study of 330 hypertensive patients on treatment attending the outpatient department of a tertiary care hospital in Mumbai. It was conducted over 8 weeks using a validated, pretested questionnaire including information on the individual's sociodemographic profile, compliance to antihypertensive therapy and lifestyle advice assessed using a 4-point Likert scale. Data were entered into MS Excel 2007 and analyzed using SPSS 20. Participants' mean age was 55.2 ± 12.6 years. 39.4% were compliant to their treatment. Common reasons for frequently skipping the dose - forgetfulness (41.2%) and discontinued the medication when feeling well (30.3%). Factors positively associated with compliance were gender and illiteracy. The proportion of noncompliance among smokers and alcoholics was statistically significant. Forgetfulness and subjective feeling of wellness were the prevalent reasons for noncompliance. Controlling habits such as smoking and alcohol may prove as key factors for compliance.

    While moderate to severely elevated blood pressure (BP) is present in nearly half of all emergency department (ED) patients, the incidence of true hypertensive emergencies in ED patients is low. Administration of bolus intravenous (IV) antihypertensive treatment to lower BP in patients without a true hypertensive emergency is a wasteful practice that is discouraged by hypertension experts; however, anecdotal evidence suggests this occurs with relatively high frequency. Accordingly, we sought to assess the frequency of inappropriate IV antihypertensive treatment in ED patients with elevated BP absent a hypertensive emergency. We performed a retrospective cohort study from a single, urban, teaching hospital. Using pharmacy records, we identified patients age 18-89 who received IV antihypertensive treatment in the ED. We defined treatment as inappropriate if documented suspicion for an indicated cardiovascular condition or acute end-organ injury was lacking. Data abstraction included adverse events and 30-day readmission rates, and analysis was primarily descriptive. We included a total of 357 patients over an 18-month period. The mean age was 55; 51% were male and 93% black, and 127 (36.4%) were considered inappropriately treated. Overall, labetalol (61%) was the most commonly used medication, followed by enalaprilat (18%), hydralazine (18%), and metoprolol (3%). There were no significant differences between appropriate and inappropriate BP treatment groups in terms of clinical characteristics or adverse events. Hypotension or bradycardia occurred in three (2%) patients in the inappropriate treatment cohort and in two (1%) patients in the appropriately treated cohort. Survival to discharge and 30-day ED revisit rates were equivalent. More than one in three patients who were given IV bolus antihypertensive treatment in the ED received such therapy inappropriately by our definition, suggesting that significant resources could perhaps be saved through education of

    Full Text Available Abstract Background Blood pressure lowering drugs are usually evaluated in short term trials determining the absolute blood pressure reduction during trough and the duration of the antihypertensive effect after single or multiple dosing. A lack of persistence with treatment has however been shown to be linked to a worse cardiovascular prognosis. This review explores the blood pressure reduction and persistence with treatment of antihypertensive drugs and the cost consequences of poor persistence with pharmaceutical interventions in arterial hypertension. Methods We have searched the literature for data on blood pressure lowering effects of different antihypertensive drug classes and agents, on persistence with treatment, and on related costs. Persistence was measured as patients' medication possession rate. Results are presented in the form of a systematic review. Results Angiotensin II receptor blocker (ARBs have a competitive blood pressure lowering efficacy compared with ACE-inhibitors (ACEi and calcium channel blockers (CCBs, beta-blockers (BBs and diuretics. 8 studies describing the persistence with treatment were identified. Patients were more persistent on ARBs than on ACEi and CCBs, BBs and diuretics. Thus the product of blood pressure lowering and persistence was higher on ARBs than on any other drug class. Although the price per tablet of more recently developed drugs (ACEi, ARBs is higher than that of older ones (diuretics and BBs, the newer drugs result in a more favourable cost to effect ratio when direct drug costs and indirect costs are also considered. Conclusion To evaluate drugs for the treatment of hypertension several key variables including the blood pressure lowering effect, side effects, compliance/persistence with treatment, as well as drug costs and direct and indirect costs of medical care have to be considered. ARBs, while nominally more expensive when drug costs are considered only, provide substantial cost savings

  13. What role does African ancestry play in how hypertensive patients respond to certain antihypertensive drug therapy?

    Seedat, Yackoob K; Brewster, Lizzy M

    2014-02-01

    This article is a summary of the response of the four commonly used antihypertensive agents in African ancestry patients. They are thiazide like diuretics or indapamide, calcium channel blockers (CCB), angiotensin converting enzyme inhibitors (ACEI) or angiotensin receptor blockers, and β-adrenergic blockers (ARB). Response was superior in African ancestry patients on a thiazide like diuretic or indapamide and CCB, while the response to β-adrenergic blockers and ACEI are attenuated. Available data are very limited but self-defined ancestry seems to be the best predictor of individual responses to antihypertensive drugs. Knowledge of the factors like economic and social consideration affect the lower rate of detection, treatment and control of hypertension in the African ancestry population of the USA. For regions in which health care resources are particularly scarce, investment in population-based primary prevention strategies may yield the largest benefit.

  14. Predictive Psychiatric Genetic Testing in Minors: An Exploration of the Non-Medical Benefits.

    Manzini, Arianna; Vears, Danya F

    2018-03-01

    Predictive genetic testing for susceptibility to psychiatric conditions is likely to become part of standard practice. Because the onset of most psychiatric diseases is in late adolescence or early adulthood, testing minors could lead to early identification that may prevent or delay the development of these disorders. However, due to their complex aetiology, psychiatric genetic testing does not provide the immediate medical benefits that current guidelines require for testing minors. While several authors have argued non-medical benefits may play a crucial role in favour of predictive testing for other conditions, little research has explored such a role in psychiatric disorders. This paper outlines the potential non-medical benefits and harms of psychiatric genetic testing in minors in order to consider whether the non-medical benefits could ever make such testing appropriate. Five non-medical themes arise in the literature: psychological impacts, autonomy/self-determination, implications of the biomedical approach, use of financial and intellectual resources, and discrimination. Non-medical benefits were prominent in all of them, suggesting that psychiatric genetic testing in minors may be appropriate in some circumstances. Further research needs to empirically assess these potential non-medical benefits, incorporate minors in the debate, and include normative reflection to evaluate the very purposes and motivations of psychiatric genetic testing in minors.

    Full Text Available Hypertension is China's leading cardiovascular disease risk factor. Improved hypertension control in China would result in result in enormous health gains in the world's largest population. A computer simulation model projected the cost-effectiveness of hypertension treatment in Chinese adults, assuming a range of essential medicines list drug costs.The Cardiovascular Disease Policy Model-China, a Markov-style computer simulation model, simulated hypertension screening, essential medicines program implementation, hypertension control program administration, drug treatment and monitoring costs, disease-related costs, and quality-adjusted life years (QALYs gained by preventing cardiovascular disease or lost because of drug side effects in untreated hypertensive adults aged 35-84 y over 2015-2025. Cost-effectiveness was assessed in cardiovascular disease patients (secondary prevention and for two blood pressure ranges in primary prevention (stage one, 140-159/90-99 mm Hg; stage two, ≥160/≥100 mm Hg. Treatment of isolated systolic hypertension and combined systolic and diastolic hypertension were modeled as a reduction in systolic blood pressure; treatment of isolated diastolic hypertension was modeled as a reduction in diastolic blood pressure. One-way and probabilistic sensitivity analyses explored ranges of antihypertensive drug effectiveness and costs, monitoring frequency, medication adherence, side effect severity, background hypertension prevalence, antihypertensive medication treatment, case fatality, incidence and prevalence, and cardiovascular disease treatment costs. Median antihypertensive costs from Shanghai and Yunnan province were entered into the model in order to estimate the effects of very low and high drug prices. Incremental cost-effectiveness ratios less than the per capita gross domestic product of China (11,900 international dollars [Int$] in 2015 were considered cost-effective.

    Previous randomised renal denervation studies did not show consistent efficacy in reducing blood pressure. The objective of our study was to evaluate the effect of renal denervation on blood pressure in the absence of antihypertensive medications. SPYRAL HTN-OFF MED was a multicentre, international, single-blind, randomised, sham-controlled, proof-of-concept trial. Patients were enrolled at 21 centres in the USA, Europe, Japan, and Australia. Eligible patients were drug-naive or discontinued their antihypertensive medications. Patients with an office systolic blood pressure (SBP) of 150 mm Hg or greater and less than 180 mm Hg, office diastolic blood pressure (DBP) of 90 mm Hg or greater, and a mean 24-h ambulatory SBP of 140 mm Hg or greater and less than 170 mm Hg at second screening underwent renal angiography and were randomly assigned to renal denervation or sham control. Patients, caregivers, and those assessing blood pressure were blinded to randomisation assignments. The primary endpoint, change in 24-h blood pressure at 3 months, was compared between groups. Drug surveillance was done to ensure patient compliance with absence of antihypertensive medication. The primary analysis was done in the intention-to-treat population. Safety events were assessed at 3 months. This study is registered with ClinicalTrials.gov, number NCT02439749. Between June 25, 2015, and Jan 30, 2017, 353 patients were screened. 80 patients were randomly assigned to renal denervation (n=38) or sham control (n=42) and followed up for 3 months. Office and 24-h ambulatory blood pressure decreased significantly from baseline to 3 months in the renal denervation group: 24-h SBP -5·5 mm Hg (95% CI -9·1 to -2·0; p=0·0031), 24-h DBP -4·8 mm Hg (-7·0 to -2·6; prenal denervation for 3-month change in both office and 24-h blood pressure from baseline: 24-h SBP -5·0 mm Hg (95% CI -9·9 to -0·2; p=0·0414), 24-h DBP -4·4 mm Hg (-7·2 to -1·6; p=0·0024), office SBP -7·7 mm Hg (-14·0

    Objective: To determine compliance, factors affecting compliance to antihypertensive therapy and to compare compliant and non-compliant groups, in a tertiary care setting. Study Design: Analytical (cross-sectional) study. Place and Duration of Study: The outpatient clinics at the Aga Khan University from May 2004 to February 2005. Patients and Methods: Two hundred patients presenting to the outpatients clinic were included. All patients 18 years and above, who had stage 1 and 2 hypertension, had one clinic visit to a medicine clinic, 6 months prior to presentation and started on antihypertensive medicines, were included. Results: Sixty-six percent were males and 33.5 % were females. Mean age was 58.1 ( +- 12) years and mean duration of hypertension was 7.2 (+- 6.7) years. Fifty-seven percent were compliant and 43% were noncompliant. In the noncompliant group, 53.4 % had mild noncompliance, 24.4 % had severe non-compliance, while 22% had moderate noncompliance. Factors of noncompliance were 56.8% missed doses due to forgetfulness, 12.7% deliberately missed their doses, 11.6% could not take the medicine due to side effects, 10.4% did not take the dose due to increased number of tablets, 4.6% were not properly counseled by the physician and 3.48% did not take medicines due to cost issues. The mean systolic blood pressure was 126 +- 19.2 mmHg in the compliant group while it was 133 +- 16.5 mmHg in the noncompliant group (p-value 0.004). The mean diastolic blood pressure in the compliant group was 76 +- 11.9 mmHg, while in the noncompliant group it was 81.9 +- 10.9 mmHg (p-value 0.001). Conclusion: Compliance to antihypertensive therapy in a tertiary care center is significantly good. Forgetfulness was the major reason for noncompliance. The mean blood pressure control was better in the compliant group. (author)

This study tested the hypothesis that blacks exhibiting EDS would have poorer self-reported adherence to hypertensive medication using cross-sectional data from the Counseling African-Americans to Control Hypertension (CAATCH trial. Methods: A total of 1,058 hypertensive blacks (average age 57±12 years participated in CAATCH, a randomized controlled trial evaluating the effectiveness of a multilevel intervention for participants who receive care from community health centers in New York City. Data analyzed in this study included baseline sociodemographics, medical history, EDS, and medication adherence. We used the Epworth Sleepiness Scale, with a cutoff score of ≥10, to define EDS. Medication adherence was measured using an abbreviated Morisky Medication Adherence scale, with a score >0 indicating nonadherence. Results: Of the sample, 71% were female, 72% received at least a high school education, 51% reported a history of smoking, and 33% had a history of alcohol consumption. Overall, 27% of the participants exhibited EDS, and 44% of those who exhibited EDS were classified as adherent to prescribed antihypertensive medications. Multivariable logistic regression analysis, adjusting for effects of age, body mass index, sex, education, and smoking and drinking history indicated that participants who exhibited EDS were more than twice as likely to be nonadherent (odds ratio 2.28, 95

    Apparent treatment-resistant hypertension (aTRH) is defined as uncontrolled hypertension despite the use of ≥3 antihypertensive medication classes or controlled hypertension while treated with ≥4 antihypertensive medication classes. Although a high prevalence of aTRH has been reported, few data are available on its association with cardiovascular and renal outcomes. We analyzed data on 14 684 Antihypertensive and Lipid-Lowering Treatment to Prevent Heart Attack Trial (ALLHAT) participants to determine the association between aTRH (n=1870) with coronary heart disease, stroke, all-cause mortality, heart failure, peripheral artery disease, and end-stage renal disease. We defined aTRH as blood pressure not at goal (systolic/diastolic blood pressure ≥140/90 mm Hg) while taking ≥3 classes of antihypertensive medication or taking ≥4 classes of antihypertensive medication with blood pressure at goal during the year 2 ALLHAT study visit (1996-2000). Use of a diuretic was not required to meet the definition of aTRH. Follow-up occurred through 2002. The multivariable adjusted hazard ratios (95% confidence intervals) comparing participants with versus without aTRH were as follows: coronary heart disease (1.44 [1.18-1.76]), stroke (1.57 [1.18-2.08]), all-cause mortality (1.30 [1.11-1.52]), heart failure (1.88 [1.52-2.34]), peripheral artery disease (1.23 [0.85-1.79]), and end-stage renal disease (1.95 [1.11-3.41]). aTRH was also associated with the pooled outcomes of combined coronary heart disease (hazard ratio, 1.47; 95% confidence interval, 1.26-1.71) and combined cardiovascular disease (hazard ratio, 1.46; 95% confidence interval, 1.29-1.64). These results demonstrate that aTRH increases the risk for cardiovascular disease and end-stage renal disease. Studies are needed to identify approaches to prevent aTRH and reduce risk for adverse outcomes among individuals with aTRH. © 2014 American Heart Association, Inc.

The duration of every therapies was 4 weeks, initial control period and wash-out period between therapies lasted 1 week. The initial daily dose of amlodipine was 5 mg, standard dose of spirapril (6 mg/daily was not changed during the trial. After 1-2 weeks of treatment amlodipine dose was increased up to 10 mg/daily as well as dihydrochlorothiazide was added, if necessary. Ambulatory blood pressure monitoring (ABPM was performed initially and at the end of both therapies.Results. Both drugs demonstrated good antihypertensive effect according to ABPM data. Decrease of systolic/diastolic blood pressure was 11,2±1,8/7,6±1,2 mm Hg in amlodipine therapy and 10,0±1,8/7,1±1,2 in spirapril therapy (p<0,0001. The smoothness indexes (SI were 0,65/0,45 and 0,55/0,45, respectively, differences between two therapies were not significant. However the individual analysis of the SI distribution (with SI=0,5 as a satisfactory criterion, showed that antihypertensive effect smoothness is better in amlodipine therapy than this in spirapril one.Conclusion. Amlodipine has prominent as well as smooth antihypertensive effect, that gives it advantages in the long-term antihypertensive therapy.

Questionnaires are an indirect measurement method that is both economic and easy to use. However, questionnaires should meet specific criteria, to minimize error and ensure reproducibility of results. Numerous studies have been conducted to design questionnaires that quantify adherence to pharmacological antihypertensive treatments. Nevertheless, it is unknown whether questionnaires fulfil the minimum requirements of validity and reliability. The aim of this study was to compile validated questionnaires measuring adherence to pharmacological antihypertensive treatments that had at least one measure of validity and one measure of reliability. Methods: A literature search was undertaken in PubMed, the Excerpta Medica Database (EMBASE, and the Latin American and Caribbean Health Sciences Literature database (Literatura Latino-Americana e do Caribe em Ciências da Saúde [LILACS]. References from included articles were hand-searched. The included papers were all that were published in English, French, Portuguese, and Spanish from the beginning of the database’s indexing until July 8, 2013, where a validation of a questionnaire (at least one demonstration of the validity and at least one of reliability was performed to measure adherence to antihypertensive pharmacological treatments.

    Full Text Available Background: Large population surveys in Malaysia have consistently shown minimal improvement of blood pressure control rates over the last 10 years. Poor adherence to antihypertensive medication has been recognized as a major reason for poor control of hypertension. This study aimed to describe the prescribing pattern of antihypertensive agents in 2 public primary care clinics and assess its appropriateness in relation to current evidence and guidelines. Methods: A cross-sectional survey to describe the prescribing pattern of antihypertensive agents was carried out in 2 publicprimary care clinics in Selangor from May to June 2009. Hypertensive patients on pharmacological treatment for ≥1 year who attended the clinics within the study period of 7 weeks were selected. Appropriate use of antihypertensive agents was defined based on current evidence and the recommendations by the Malaysian Clinical Practice Guidelines (CPG on the Management of Hypertension, 2008. Data were obtained from patients’ medical records and were analysed using the SPSS software version 16.0. Results: A total of 400 hypertensive patients on treatment were included. Mean age was 59.5 years (SD ±10.9, range 28 to91 years, of which 52.8% were females and 47.2% were males. With regards to pharmacotherapy, 45.7% were on monotherapy,43.3% were on 2 agents and 11.0% were on ≥3 agents. Target blood pressure of <140/90mmHg was achieved in 51.4% of patients on monotherapy, and 33.2% of patients on combination of ≥2 agents. The commonest monotherapy agents being prescribed were β-blockers (atenolol or propranolol, followed by the short-acting calcium channel blocker (nifedipine. The commonest combination of 2-drug therapy prescribed was β-blockers and short-acting calcium channel blocker. Conclusion: This study shows that the prescribing pattern of antihypertensive agents in the 2 primary care clinics was not in accordance with current evidence and guidelines.

    Peptides with antihypertensive potency have long been attractive to the medical and food communities. However, serving as food additives, rather than therapeutic agents, peptides should have a good taste. In the present study, we explore the intrinsic relationship between the angiotensin I-converting enzyme (ACE) inhibition and bitterness of short peptides in the framework of computational peptidology, attempting to find out the appropriate properties for functional food peptides with satisfactory bioactivities. As might be expected, quantitative structure-activity relationship modeling reveals a significant positive correlation between the ACE inhibition and bitterness of dipeptides, but this correlation is quite modest for tripeptides and, particularly, tetrapeptides. Moreover, quantum mechanics/molecular mechanics analysis of the structural basis and energetic profile involved in ACE-peptide complexes unravels that peptides of up to 4 amino acids long are sufficient to have efficient binding to ACE, and more additional residues do not bring with substantial enhance in their ACE-binding affinity and, thus, antihypertensive capability. All of above, it is coming together to suggest that the tripeptides and tetrapeptides could be considered as ideal candidates for seeking potential functional food additives with both high antihypertensive activity and low bitterness.

    Hypertension represents a major health problem primarily because of its role in contributing to the initiation and progression of major cardiovascular diseases. Concerns pertaining to hypertension and its sequelae can be substantially addressed and consequent burden of disease reduced by early detection and appropriate therapy of elevated blood pressure. This cross-sectional observational study aims at analyzing the utilization pattern of antihypertensives used for the treatment of hypertension at a tertiary care hospital in perspective of standard treatment guidelines. Prescriptions were screened for antihypertensives at the medicine outpatient department of a tertiary care teaching hospital. Medical records of the patients were scrutinized after which 286 prescriptions of patients suffering from hypertension were included. The collected data were sorted and analyzed on the basis of demographic characteristics and comorbidities. The calcium channel blockers were the most frequently used antihypertensive class of drugs (72.3%). Amlodipine (55.6%) was the single most frequently prescribed antihypertensive agent. The utilization of thiazide diuretics was 9%. Adherence to the National List of Essential Medicines (NLEMs) was 65%. The combination therapy was used more frequently (51.5%) than monotherapy (48.8%). The use of angiotensin-converting enzyme inhibitors/angiotensin 2 receptor blockers (ACE-I/ARB) was 41.4% in diabetes. The treatment pattern, in general, conformed to standard treatment guidelines. Few areas, however, need to be addressed such as the underutilization of thiazide diuretics, need for more awareness of drugs from the NLEMs and enhanced use of ACE-I/ARB in diabetic hypertensives.

    Male fertility significantly decreased in the last 50 years, as showed in several studies reporting a reduction of sperm counts per ml in the seminal fluid. Several "acute" pharmacological treatments, as antibiotics, could cause subclinical and temporary reduction of male fertility; conversely, long-term medical treatment may severely affect male fertility, although this effect could be considered transient in most of the cases. Thus, nowadays, several long-term pharmacological treatments may represent a clinical challenge. The association between several kind of antihypertensive drugs and reduction of male fertility has been showed in the mouse model, although the modification(s) which may alter this fine-regulated machinery are still far to be elucidated. Furthermore, well-designed observational studies and randomized controlled trials are needed to accurately define this association in human model, meaning a narrative overview synthesizing the findings of literature retrieved from searches of computerized databases. We strongly solicit future human studies (both observational and randomized clinical trials) on large cohorts with adequate statistical power which may clarify this possible association and the effects (reversible or permanent) of each drug. Furthermore, we suggest a close collaboration between general practitioners, cardiologists, and andrologists in order to choose the most appropriate antihypertensive therapy considering also patient's reproductive desire and possible risk for his fertility.

    The aim of this study was to investigate the antihypertensive effect of leaves Mangifera indica L. using in vitro and in vivo assays. The ethanol extract of leaves of M. indica was fractionated to dichloromethanic, n-butyl alcohol and aqueous fractions. The chemical composition of ethanolic extract and dichloromethanic fraction were evaluated by liquid chromatography coupled with tandem mass spectrometry (LC-MS/MS). Antioxidant activity was evaluated in the DPPH scavenging activity assay. Angiotensin-converting enzyme (ACE) inhibitory activity was investigated using in vitro and in vivo assays. The chronic antihypertensive assay was performed in spontaneously hypertensive rats (SHRs) and Wistar rats treated with enalapril (10 mg/kg), dichloromethanic fraction (100 mg/kg; twice a day) or vehicle control for 30 days. The baroreflex sensitivity was evaluated through the use of sodium nitroprusside and phenylephrine. Cardiac hypertrophy was evaluated by morphometric analysis. The dichloromethanic fraction exhibited the highest flavonoid, total phenolic content and high antioxidant activity. Dichloromethanic fraction elicited ACE inhibitory activity in vitro (99 ± 8%) similar to captopril. LC-MS/MS analysis revealed the presence of ferulic acid (48.3 ± 0.04 µg/g) caffeic acid (159.8 ± 0.02 µg/g), gallic acid (142.5 ± 0.03 µg/g), apigenin (11.0 ± 0.01 µg/g) and quercetin (203.3 ± 0.05 µg/g). The chronic antihypertensive effects elicited by dichloromethanic fraction were similar to those of enalapril, and the baroreflex sensitivity was normalized in SHR. Plasma ACE activity and cardiac hypertrophy were comparable with animals treated with enalapril. Dichloromethanic fraction of M. indica presented an antihypertensive effect, most likely by ACE inhibition, with benefits in baroreflex sensitivity and cardiac hypertrophy. Altogether, the results of the present study suggest that the dichloromethanic fraction of M. indica leaves may have potential as a promoting

    Elevated nighttime blood pressure (BP) and a reduced day-night BP fall ("nondipping" condition) are strong predictors of cardiovascular complications, both in hypertension and in the general population. A reduced or inverted nocturnal BP fall might also be theoretically used to define the most appropriate timing for drug administration. In a systematic review of the available evidence, we show that bedtime dosing of antihypertensive medication reduces nocturnal BP and increases day-night BP fall more than standard morning dosing. The effects of such an approach on average 24-hour BP are more modest and less univocal, with a considerable between-center heterogeneity. Admittedly, the mechanisms underlying non-dipping condition have not been fully understood yet, and it is still a matter of debate whether restorating a dipping pattern may reduce the cardiovascular risk associated with non-dipping independently from the effects on 24-hour BP. Under this regard, evidence from a single trial strongly suggests that bedtime dosing of antihypertensive medications may greatly reduce cardiovascular morbidity in hypertensive patients. The provocative results of that trial deserve to be explored further in larger intervention trials.

    The purpose of this study was to examine the relationship between self-transcendence and medication adherence among older adults prescribed antihypertensive medication. Descriptive, correlational research design. Forty-six older adults who were prescribed antihypertensive medications from an independent living facility participated in this study. Participants were given a survey that included a demographic questionnaire, the Morisky Medication Adherence Scale, and Reed's Self-Transcendence Scale. No significant relationship was found between medication adherence and self-transcendence (r = -.20, p = .18). Ninety percent of the participants however, admitted to cutting back or stopping their medication without notifying their providers. Continued investigation is needed to identify reasons why older adults fail to adhere to taking prescribed hypertension medications in order to improve health outcomes in this population. © The Author(s) 2014.

    To test whether a multifaceted prospective memory intervention improved adherence to antihypertensive medications and to assess whether executive function and working memory processes moderated the intervention effects. Two-group longitudinal randomized control trial. Community. Individuals aged 65 and older without signs of dementia or symptoms of severe depression who were self-managing prescribed medication. After 4 weeks of initial adherence monitoring using a medication event monitoring system, individuals with 90% or less adherence were randomly assigned to groups. The prospective memory intervention was designed to provide strategies that switch older adults from relying on executive function and working memory processes (that show effects of cognitive aging) to mostly automatic associative processes (that are relatively spared with normal aging) for remembering to take medications. Strategies included establishing a routine, establishing cues strongly associated with medication taking actions, performing the action immediately upon thinking about it, using a medication organizer, and imagining medication taking to enhance encoding and improve cuing. There was significant improvement in adherence in the intervention group (57% at baseline to 78% after the intervention), but most of these gains were lost after 5 months. The control condition started at 68% and was stable during the intervention, but dropped to 62%. Executive function and working memory moderated the intervention effect, with the intervention producing greater benefit for those with lower executive function and working memory. The intervention improved adherence, but the benefits were not sustained. Further research is needed to determine how to sustain the substantial initial benefits. © 2016, Copyright the Authors Journal compilation © 2016, The American Geriatrics Society.

    A drop in postural blood pressure (BP) may contribute to falls, while antihypertensives have been considered to induce postural drop or orthostatic hypotension (OH) and falls among older people. However, this relationship between antihypertensives, postural BP and the risk of falls has never been evaluated in a single study. To examine the association of postural BP changes and BP therapy with the risk of falls among community-dwelling older people in a case-control manner. Cases (n = 202) included participants aged ≥ 65 years with two falls or one injurious fall while controls (n = 156) included participants ≥ 65 years with no falls in the preceding 12 months. Antihypertensives usage and medical history were recorded. Supine BP measurements were obtained at 10 min rest and at 1, 2 and 3 min after standing. Orthostatic hypotension was defined as a reduction in BP of 20/10 mmHg within 3 min of standing. Individual antihypertensive classes were not associated with falls. Minimal standing systolic BP (SBP) was significantly lower among fallers [128 (± 27·3) vs. 135·7 (± 24·7) mmHg; P = 0·01], but fallers were not more likely to fulfil the diagnostic criteria for OH. Diuretics were associated with OH and α-blockers were associated with minimal standing SBP. Univariate analysis revealed that the use of ≥ 2 antihypertensives was associated with recurrent and injurious falls [OR,1.97;CI,1.2-3.1], which was no longer significant aftermultivariateadjustment for age and number of comorbidities [OR, 1.6; CI, 0.95-2.6]. Minimal standing SBP or a lower SBP at 2 or 3minutes standing was associated with falls rather than OH using consensus definition. Association between ≥ 2 antihypertensives and falls was attenuated by increasing age and comorbidities. Our findings challenge previous assumptions that OH or the use of antihypertensives is associated with falls. Future studies should now seek to link these findings prospectively with falls in order to guide decision

    Diagnostic radiology has an image problem. In its effort to develop a better understanding of benefit-risk in medical radiology, data on potential risks associated with medical imaging have been welcomed into the medical community. As such, risk perspectives and mantras from the occupational health profession have been adopted and applied to patients. These perspectives often focus on risk with only casual, incidental, or no reference to the benefits experienced by patients. These occupational health viewpoints have accumulated over decades, have overshadowed a very limited perspective about the benefits of medical X-rays, and have become an integrated part of our profession. This review argues that the medical profession should abandon perspectives on risk that are adopted from occupational health professions and focus on perspectives that realistically focus on the medical benefit-risk for patients.

    Full Text Available Objective: To determine if pharmacist-provided medication therapy management (MTM improves medication adherence in Medicare patients. A secondary objective is to compare the total monthly cost of a patient’s prescription medication regimen 6 months before and 6 months following a comprehensive medication review (CMR. Design: Retrospective analysis of medication adherence, pre-post comparison. Setting: Three independent pharmacies in North Carolina. Patients: 97 Medicare Part D beneficiaries with one or more chronic disease states who participated in a comprehensive medication review (CMR. Intervention: MTM services provided by community pharmacists. Main outcome measure: Change in adherence as measured by the proportion of days covered (PDC and change in medication costs for patients and third party payers. Results: Patients were adherent to chronic disease-state medications before and after MTM (PDC≥ 0.8. Overall, change in mean adherence before and after MTM did not change significantly (0.87 and 0.88, respectively; p = 0.43. However, patients taking medications for cholesterol management, GERD, thyroid and BPH demonstrated improved adherence following a CMR. No change in adherence was noted for patients using antihypertensives and antidiabetic agents. Average total chronic disease-state medication costs for participants were reduced from $210.74 to $193.63 (p=0.08 following the comprehensive medication review. Total costs for patient and third party payers decreased from patients prescribed antilipemics, antihypertensives, GERD and thyroid disorders following a CMR. Conclusions: Pharmacist-provided MTM services were effective at improving medication adherence for some patients managed with chronic medications. Pharmacist-provided MTM services also were effective in decreasing total medication costs.

  18. What are the benefits of medical screening and surveillance?

    Full Text Available Pre-employment examination is considered to be an important practice and is commonly performed in several countries within the European Union. The benefits of medical surveillance programmes are not generally accepted and their structure is often inconsistent. The aim of this review was to evaluate, on the basis of the available literature, the usefulness of medical screening and surveillance. MEDLINE was searched from its inception up to March 2010. Retrieved literature was evaluated in a peer-review process and relevant data was collected following a systematic extraction schema. Pre-placement screening identifies subjects who are at an increased risk for developing work-related allergic disease, but pre-employment screening is too low to be used as exclusion criteria. Medical surveillance programmes can identify workers who have, or who are developing, work-related asthma. These programmes can also be used to avoid worsening of symptoms by implementing preventive measures. A combination of different tools within the surveillance programme, adjusted for the risk of the individual worker, improves the predictive value. Medical surveillance programmes provide medical as well as socioeconomic benefits. However, pre-employment screening cannot be used to exclude workers. They may act as a starting point for surveillance strategies. A stratified approach can increase the effectiveness and reduce the costs for such programmes.

    2005-08-01

    Full Text Available OBJECTIVE: To evaluate the efficacy, safety and tolerability of sildenafil among Brazilian patients with hypertension treated with combinations of anti-hypertensive drugs. MATERIALS AND METHODS: One hundred twenty hypertensive men aged 30 to 81 years old under treatment with 2 or more anti-hypertensive drugs and with erectile dysfunction (ED lasting for at least 6 months were enrolled at 7 research centers in Brazil. Patients were randomized to receive treatment with either sildenafil or placebo taken 1 hour before sexual intercourse (initial dose of 50 mg, adjusted to 25 mg or 100 mg according to efficacy and toxicity. During the following 8 weeks, patients were evaluated regarding vital signs, adverse events, therapeutic efficacy, satisfaction with treatment and use of concurrent medications. RESULTS: The primary evaluation of efficacy, which was based on responses to questions 3 and 4 of the International Index of Erectile Function, showed significant differences regarding treatment with sildenafil (p = 0.0002 and p < 0.0001, respectively. In the assessment of global efficacy, 87% of the patients treated with sildenafil reported improved erections, as compared with 37% of patients given placebos (p < 0.0001. The other secondary evaluations supported the results favoring sildenafil. The most frequent adverse events among patients treated with sildenafil were headaches (11.4%, vasodilation (11.4% and dyspepsia (6.5%. There were no significant changes in blood pressure measurements in both groups. CONCLUSION: Sildenafil is efficacious and safe for the treatment of hypertensive patients with ED who receive concurrent combinations of anti-hypertensive drugs.

    2018-06-14

    This is an in-depth review on the mechanism of action, clinical utility, and drug-drug interactions of colchicine in the management of pericardial disease. Recent evidence about therapeutic targets on pericarditis has demonstrated that NALP3 inflammasome blockade is the cornerstone in the clinical benefits of colchicine. Such benefits extend from acute and recurrent pericarditis to transient constriction and post-pericardiotomy syndrome. Despite the increased utilization of colchicine in cardiovascular medicine, safety concerns remains unsolved regarding the long-term use of colchicine in the cardiac patient. Moreover, recent evidence has demonstrated that numerous cardiovascular medications, ranging from antihypertensive medication to antiarrhythmics, are known to interact with the CYP3A4 and/or P-gp system increasing the toxicity potential of colchicine. The use of adjunctive colchicine in the management of inflammatory pericardial diseases is standard of care in current practice. It is advised that a careful medication reconciliation with emphasis on pharmacokinetic is completed before prescribing colchicine in order to avoid harmful interaction by finding an alternative regimen or adjusting colchicine dosing.

    2015-01-01

    This study examines Korean American community newspapers' representation of risks and benefits involved with medical tourism offered in Korea. Using framing theory, this research attempts to explain Korean Americans' highly positive perceptions and high willingness to use health and medical services in Korea through medical tourism rather than using such services in the United States. The result of content analyses indicated that Korean American community newspapers are rarely engaged in risk communication and lack sufficient information about potential risks of medical tourism while emphasizing diverse benefits. Korean ethnic media, as the primary source of health communication for Korean Americans, should provide more reliable health and medical information for the population's appropriate health management.

    Full Text Available Background . Hypertension is a civilization disease which currently affects about 10.5 m people in Poland. The number of patients with diagnosed, untreated hypertension amounts to 18%, and as many as 45% of patients are treated ineffectively whereas only 26% are treated effectively. Impedance cardiography (IC is an important tool both in diagnostics and the treatment of hypertensive patients, particularly in the case of antihypertensive treatment resistance. This method allows for the individualized treatment of each patient on the basis of hemodynamic parameters, monitoring of hypertensive patients in the outpatient care setting, and the assessment of cardiovascular risk factors. Objectives . The aim of the study was to evaluate the efficacy of hypotensive medications in patients with hypertension using impedance cardiography. Material and methods. The study involved 60 hypertensive patients, treated with antihypertensives, who failed to achieve the required blood pressure values. The modification of hypertension therapy was based on EBM (evidence-based medicine and on hemodynamic parameters obtained using impedance cardiography. Results . It was found that high blood pressure therapy based on impedance cardiography parameters has a significant influence on blood pressure reduction compared to EM B-based therapy: below 140/90: 66.8 vs. 55.1% and below 130/80: 23.5 vs. 18.9%. Conclusions . On the basis of this study it was confirmed that impedance cardiography allows for a significant reduction of hypertension and the selection of the most effective therapeutic strategy, providing for the optimization and efficacy of hypertension treatment.

    One previous large cross-sectional study across four countries suggests that riboflavin intake may be inversely associated with blood pressure. The aim of this analysis was to investigate a possible association between riboflavin intake and change in blood pressure over 5 years. The study population comprised Chinese men and women who participated in the Jiangsu Nutrition Study. Quantitative data relating to riboflavin intake at baseline in 2002 and measurements of blood pressure at baseline and follow-up in 2007 were available for 1,227 individuals. Overall, 97.2% of the participants had inadequate riboflavin intake (below the Estimated Average Requirement). In multivariable analysis adjusted for sociodemographic and lifestyle factors and dietary patterns, a higher riboflavin intake was inversely associated with change in systolic blood pressure (p = .036). In participants taking antihypertensive medication at baseline, the relationship between riboflavin intake and systolic blood pressure persisted; whereas, in those not taking antihypertensive medication, the diastolic blood pressure was less likely to increase with the increasing intake of riboflavin (p = .031). There was a three-way interaction between antihypertensive medications, body mass index, and riboflavin intake. Among those who were obese and taking antihypertensive medication, a higher riboflavin intake was associated with a smaller increment in systolic blood pressure and pulse pressure. There are complex interactions between riboflavin intake and blood pressure change that depend on prior antihypertensive use and the presence or absence of obesity.

    To explore the potential benefits and challenges of involving adolescents in the education of medical students and residents from the perspectives of adolescents who are hospitalized with chronic health conditions. We conducted qualitative interviews with adolescents at a Canadian pediatric hospital. Eligible participants were those between 13-18 years of age, with chronic health conditions lasting more than three months who were feeling well enough to participate in an interview. We used conventional content analysis to analyze the data. Sixteen adolescents participated in the study. In terms of benefits, the participants described how involving adolescents in the education of medical students and residents would improve patient-physician interactions, increase patients' confidence and self-worth, encourage patients to self-reflect and gain knowledge about their health conditions and themselves, as well as enable patients to socialize with other patients. When asked about the challenges, the participants discussed how it might be difficult to include diverse patient perspectives, manage adolescents' negativity, and ensure that learners are non-judgmental towards adolescents and take them seriously. While many of the reported benefits and challenges correspond with those featured in the literature on adult patient involvement in medical education, our findings underscore the distinctive benefits and challenges that medical educators may experience in designing and implementing educational initiatives that involve adolescents. Through the future design and implementation of educational initiatives, it is important to further explore the benefits and challenges of such adolescent involvement, as we know that adolescents can be valuable contributors to medical education.

    Full Text Available In the background of debates on Universal Health Coverage, skill transfer from the medical practice license holders to other health-care providers such as nurse practitioner has become a global norm. In India, where the world's largest numbers of medical graduates are produced, this discussion is expanding to extremes and serious suggestions are coming forward for the development of legal framework for allowing dentists, homeopaths, pharmacists, and half duration trained doctors; permission to issue allopathic prescription. Allopathic medical prescription. It is noteworthy that this discussion only pertains to the pharmaceutical products retailed through “allopathic medical prescriptions.” A prescription is not only advice for patient's recovery but it also is a legitimate order for the sale of controlled drugs and pharmaceutical product; thereby functions as a regulatory tool for consumption of pharmaceutical products at retail level. Who is ultimately going to benefit from this prescription deregulation? This editorial explores benefits and pitfalls of prescription and medical practice deregulation.

    To compare the association between antihypertensive drug treatment and heart failure (HF) risk with the association between engaging in a healthy lifestyle and HF risk. We prospectively investigated the single and joint associations of lifestyle factors and awareness, treatment, blood pressure control status with HF risk among 38 075 Finns, who were 25-74 years old and free of HF at baseline. During a median follow-up of 14.1 years, 638 men and 445 women developed HF. Engaging in a healthy lifestyle was associated with an decreased risk of HF. Compared with normotensive people, hypertensive patients with and without antihypertensive treatment had a higher risk of HF. Hypertensive patients who used antihypertensive drugs but did not engage in a healthy lifestyle had a significantly higher risk of HF [HR 1.75; 95% confidence interval (CI) 1.39-2.21] than hypertensive patients who did not use antihypertensive drugs but engaged in a healthy lifestyle. In addition, compared with hypertensive patients who used antihypertensive drugs and engaged in a healthy lifestyle, hypertensive patients who did not use antihypertensive drug or engage in a healthy lifestyle had a significantly higher risk of HF (HR 1.55; 95% CI 1.24-1.95). The present study demonstrates that HF risk was lower in hypertensive patients who engaged in a healthy lifestyle but higher in hypertensive people using antihypertensive drug treatment.

    Introduction: The majority of medical graduates in Germany complete a doctorate, even though a doctoral degree is not necessary for the practice of medicine. So far, little is known about doctoral candidates’ view on the individual benefit a doctoral thesis has for them. Consequently, this is the subject of the present investigation. Method: Data from surveys with graduates of the five medical faculties of Baden-Württemberg from the graduation years 2007/2008 (N=514) and 2010/2011 (N=598) were analysed. Results: One and a half years after graduating 53% of those interviewed had completed their doctorate. When asked about their motivation for writing a doctoral thesis, participants answered most frequently “a doctorate is usual” (85%) and “improvement of job opportunities” (75%), 36% said that an academic career has been their primary motive. Less than 10% responded that they used their doctoral thesis as a means to apply for a job. The proportion of graduates working in health care is equally large among those who have completed a thesis and those who have not. Graduates who pursued a thesis due to scientific interest are also currently more interested in an academic career and recognise more opportunities for research. An implicit benefit of a medical thesis emerged with regard to the self-assessment of scientific competences as those who completed a doctorate rated their scientific competencies higher than those who have not. Discussion: Although for the majority of physicians research interest is not the primary motivation for completing a doctorate, they might nevertheless achieve some academic competencies. For graduates pursuing an academic career the benefit of completing a medical thesis is more obvious. PMID:26958656

    To determine the change in neurocognitive test performance in children with primary hypertension after initiation of antihypertensive therapy. Subjects with hypertension and normotensive control subjects had neurocognitive testing at baseline and again after 1 year, during which time the subjects with hypertension received antihypertensive therapy. Subjects completed tests of general intelligence, attention, memory, executive function, and processing speed, and parents completed rating scales of executive function. Fifty-five subjects with hypertension and 66 normotensive control subjects underwent both baseline and 1-year assessments. Overall, the blood pressure (BP) of subjects with hypertension improved (24-hour systolic BP load: mean baseline vs 1 year, 58% vs 38%, P < .001). Primary multivariable analyses showed that the hypertension group improved in scores of subtests of the Rey Auditory Verbal Learning Test, Grooved Pegboard, and Delis-Kaplan Executive Function System Tower Test (P < .05). However, the control group also improved in the same measures with similar effects sizes. Secondary analyses by effectiveness of antihypertensive therapy showed that subjects with persistent ambulatory hypertension at 1 year (n = 17) did not improve in subtests of Rey Auditory Verbal Learning Test and had limited improvement in Grooved Pegboard. Overall, children with hypertension did not improve in neurocognitive test performance after 1 year of antihypertensive therapy, beyond that also seen in normotensive controls, suggesting improvements with age or practice effects because of repeated neurocognitive testing. However, the degree to which antihypertensive therapy improves BP may affect its impact upon neurocognitive function. Copyright © 2017 Elsevier Inc. All rights reserved.

    To determine the association between health insurance/health benefit and medication adherence amongst adult diabetic patients in Kingston, Jamaica. This was a cross-sectional study. The target population was diabetics who attended the diabetic outpatient clinics in health centres in Kingston. Two health centres were selectively chosen in Kingston. All diabetic patients attending the diabetic clinics and over the age of 18 years were conveniently sampled. The sample size was 260. An interviewer-administered questionnaire was utilized which assessed health insurance/health benefit. Adherence was measured by patients' self-reports of medication usage in the previous week. The Chi-squared test was used to determine the significance of associations. Sample population was 76% female and 24% male. Type 2 diabetics comprised 93.8%. More than 95% of patients were over the age of 40 years. Approximately 32% of participants were employed. Approximately 75% of patients had health insurance/health benefit. Among those who had health insurance or health benefit, 71.5% were adherent and 28.5% were non-adherent. This difference was statistically significant (χ2 = 6.553, p = 0.01). Prevalence of medication non-adherence was 33%. AIn Kingston, diabetic patients who are adherent are more likely to have health insurance/health benefit ( p = 0.01).

Linkage analysis identified a region on chromosome 2 that was investigated using 70 single nucleotide polymorphisms (SNPs typed in 7 positional candidate genes, including adducin 2 (ADD2. Method To investigate whether blood pressure (BP levels in these hypertensives (n = 1133 were influenced by gene-by-drug interactions, we used cross-validation statistical methods (i.e., estimating a model for predicting BP levels in one subgroup and testing it in a different subgroup. These methods greatly reduced the chance of false positive findings. Results Eight SNPs in ADD2 were significantly associated with systolic BP in untreated hypertensives (p-value Conclusion Our findings suggest that hypertension candidate gene variation may influence BP responses to specific antihypertensive drug therapies and measurement of genetic variation may assist in identifying subgroups of hypertensive patients who will benefit most from particular antihypertensive drug therapies.

    Data from randomized controlled trials to guide antihypertensive agent choice for chronic hypertension in pregnancy are limited; this study aimed to compare labetalol and nifedipine, additionally assessing the impact of ethnicity on treatment efficacy. Pregnant women with chronic hypertension (12 +0 -27 +6 weeks' gestation) were enrolled at 4 UK centers (August 2014 to October 2015). Open-label first-line antihypertensive treatment was randomly assigned: labetalol- (200-1800 mg/d) or nifedipine-modified release (20-80 mg/d). Analysis included 112 women (98%) who completed the study (labetalol n=55, nifedipine n=57). Maximum blood pressure after randomization was 161/101 mm Hg with labetalol versus 163/105 mm Hg with nifedipine (mean difference systolic: 1.2 mm Hg [-4.9 to 7.2 mm Hg], diastolic: 3.3 mm Hg [-0.6 to 7.3 mm Hg]). Mean blood pressure was 134/84 mm Hg with labetalol and 134/85 mm Hg with nifedipine (mean difference systolic: 0.3 mm Hg [-2.8 to 3.4 mm Hg], and diastolic: -1.9 mm Hg [-4.1 to 0.3 mm Hg]). Nifedipine use was associated with a 7.4-mm Hg reduction (-14.4 to -0.4 mm Hg) in central aortic pressure, measured by pulse wave analysis. No difference in treatment effect was observed in black women (n=63), but a mean 4 mm Hg reduction (-6.6 to -0.8 mm Hg; P =0.015) in brachial diastolic blood pressure was observed with labetalol compared with nifedipine in non-black women (n=49). Labetalol and nifedipine control mean blood pressure to target in pregnant women with chronic hypertension. This study provides support for a larger definitive trial scrutinizing the benefits and side effects of first-line antihypertensive treatment. URL: https://www.isrctn.com.

    This study explores the benefits and risks featured in medical tourism broker websites, as well as the types of persuasive appeals that these websites use to attract potential customers, from a framing theory perspective. In addition, it examines relationships among types of appeals and specific types of health-related services offered by medical facilities abroad and the role of new media modalities within medical tourism broker sites. A content analysis of 91 medical tourism broker websites was conducted. The results indicate that the websites highly emphasized benefits while downplaying the risks. Specifically, despite offering consumers complicated and risky medical procedures, the websites failed to report any procedural, postoperative, or legal concerns associated with them. Moreover, the results indicated that the websites relied on heavy use of new media features to enhance the appeal of the medical services that were offered. The implications of these findings, future directions for research, and limitations of the study are discussed.

    Cost-effectiveness analysis is an approach used to determine the value of a medical care option and refers to a method used to assess the costs and health benefits of an intervention. Upon the diagnosis of liver cirrhosis, the current guidelines recommend that all cirrhotic patients have to be screened for the presence of esophageal varices by endoscopy. In addition, patients with a positive family history of esophageal cancer are screened annually. These approaches place a heavy burden on endoscopy units, and repeated testing over time may have a detrimental effect on patient compliance. Following the recommendations of a recent study entitled 'Detection of risky esophageal varices using two dimensional ultrasound: when to perform endoscopy', the intra-abdominal portion of the esophagus of 1100 patients was divided into a hepatic group, which included 650 patients, and a nonhepatic group, which included 450 patients, who presented with manifestations of liver diseases and gastrointestinal symptoms, respectively, and were examined using standard two-dimensional ultrasound (US) to evaluate cost effectiveness, standard issues, and medical benefits using conventional US. The overall effectiveness analysis of 1100 patients yielded a 41% cost standard benefit calculated to be $114,760 in a 6-month study. Two-dimensional US can play an important role in screening for esophageal abnormalities, thus saving money and time. The esophagus should be screened during routine conventional abdominal US.

    Drug repositioning refers to the process of developing new indications for existing drugs. As a phenotypic indicator of drug response in humans, clinical side effects may provide straightforward signals and unique opportunities for drug repositioning. We aimed to identify drugs frequently associated with hypotension adverse reactions (ie, the opposite condition of hypertension), which could be potential candidates as antihypertensive agents. We systematically searched the electronic records of the US Food and Drug Administration (FDA) Adverse Event Reporting System (FAERS) through the openFDA platform to assess the association between hypotension incidence and antihypertensive therapeutic effect regarding a list of 683 drugs. Statistical analysis of FAERS data demonstrated that those drugs frequently co-occurring with hypotension events were more likely to have antihypertensive activity. Ranked by the statistical significance of frequent hypotension reporting, the well-known antihypertensive drugs were effectively distinguished from others (with an area under the receiver operating characteristic curve > 0.80 and a normalized discounted cumulative gain of 0.77). In addition, we found a series of antihypertensive agents (particularly drugs originally developed for treating nervous system diseases) among the drugs with top significant reporting, suggesting the good potential of Web-based and data-driven drug repositioning. We found several candidate agents among the hypotension-related drugs on our list that may be redirected for lowering blood pressure. More important, we showed that a pharmacovigilance system could alternatively be used to identify antihypertensive agents and sustainably create opportunities for drug repositioning.

    To determine the incidence and cost of medications dispensed despite discontinuation (MDDD) of the medications in the electronic medical record within an integrated health care organization. Dean Health System, with medical clinics and pharmacies linked by an electronic medical record, and a shared health plan and pharmacy benefits management company. Pharmacist-led quality improvement project using retrospective chart review. Electronic medical records, pharmacy records, and prescription claims data from patients 18 years of age or older who had a prescription filled for a chronic condition from June 2012 to August 2013 and submitted a claim through the Dean Health Plan were aggregated and cross-referenced to identify MDDD. Descriptive statistics were used to characterize demographics and MDDD incidence. Fisher's exact test and independent samples t tests were used to compare MDDD and non-MDDD groups. Wholesale acquisition cost was applied to each MDDD event. 7,406 patients met inclusion criteria. For 223 (3%) patients with MDDD, 253 independent events were identified. In terms of frequency per category, antihypertensive agents topped the list, followed, in descending order, by anticonvulsants, antilipemics, antidiabetics, and anticoagulants. Nine medications accounted for 59% (150 of 253) of all MDDD events; these included (again in descending order): gabapentin, atorvastatin, simvastatin, hydrochlorothiazide, lisinopril, warfarin, furosemide, metformin, and metoprolol. Mail-service pharmacies accounted for the highest incidence (5.3%) of MDDD, followed by mass merchandisers (4.6%) and small chains (3.9%). The total cost attributable to MDDD was $9,397.74. Development of a technology-based intervention to decrease the incidence of MDDD may be warranted to improve patient safety and decrease health care costs.

  5. Ambulatory Blood Pressure Monitoring for the Effective Management of Antihypertensive Drug Treatment.

    Science.gov (United States)

    O'Brien, Eoin; Dolan, Eamon

    2016-10-01

    This purpose of this article is to review the current recommendations for ambulatory blood pressure measurement (ABPM) and the use of ABPM in assessing treatment. We review current international guidelines and undertake a critical review of evidence supporting the clinical use of ABPM in effectively managing antihypertensive drug treatment. Current guidelines emphasize the diagnostic superiority of ABPM, mainly from the ability of the technique to identify sustained hypertension by allowing for the exclusion of white-coat hypertension and by demonstrating the presence of masked hypertension. ABPM also offers diagnostic insights into nocturnal patterns of blood pressure, such as dipping and nondipping, reverse dipping, and excessive dipping, and the presence of nocturnal hypertension; although less attention is given to the nocturnal behavior of blood pressure in clinical practice, the nocturnal patterns of blood pressure have particular relevance in assessing the response to blood pressure-lowering medication. Surprisingly, although the current guidelines give detailed recommendations on the diagnostic potential and use of ABPM, there are scant recommendations on the benefits and application of the technique for the initiation of blood pressure-lowering therapy in clinical practice and virtually no recommendations on how it might be used to assess the efficacy of drug treatment. In view of a deficiency in the literature on the role of ABPM in assess the efficacy of drug treatment, we put forward proposals to correct this deficiency and guide the prescribing physician on the most appropriate drug administration and dosage over time.

    A Visual Analog Scale (VAS) is useful for diagnosing medication nonadherence and its validity has been evaluated using electronic pillbox as the gold standard. We have developed the EvaLobs ® scale for use on paper or on smartphone and the aim of the study was to administrate the scale among FLAHS 2017 participants treated for an hypertension, a dyslipidemia or diabetes. In subjects treated with antihypertensive medications, participants completed the 6-item Girerd Scale and EvaLobs ® . The French League Against Hypertension Survey (FLAHS) are carried out by self-questionnaire sent by mail to individuals from the French Kantar Health sampling frame (representative panel of the population living in metropolitan France). In 2017, FLAHS was conducted in 4783 subjects aged 35 and over. The EvaLobs ® has a scale from 0 to 15 and the use instruction is "how many days have you taken the drug in the past 15 days". A score>12 indicates a "good compliance". The 6-item Girerd scale was also completed. "Good adherence" was determined for a score of 0 to 2 and "nonadherence" for a score of 3 or more. The agreement between EvaLobs ® and the 6-item Girerd scale was evaluated in treated hypertensives. The survey included 4783 subjects with 1308 treated hypertensives, 942 subjects treated with lipid-lowering drugs and 405 subjects treated with anti-diabetics. EVALOBS ® indicates "Good adherence" in 96% of subjects and the 6 questions questionnaire indicates "good adherence" in 95% of subjects. An excellent agreement is noted in 93.8%. An EvaLobs ® score indicating nonadherence or an absence of response to EvaLobs ® is observed in 3.6% [CI 95, 2.5-4.7] of hypertensives, in 6.0% [CI 95, 3.9-8.1] of diabetics and in 8.2% [CI 95, 6.5-9.9] of dyslipidemic patients. In the population living in France and in unselected patients treated for metabolic disease or hypertension, non-adherence is lowest for antihypertensive medications and highest for statins.

    Although Electronic Medical Record (EMR) systems provide various benefits, there are both advantages and disadvantages regarding its cost-effectiveness. This study analyzed the economic effects of EMR systems using a cost-benefit analysis based on the differential costs of managerial accounting. Samsung Medical Center (SMC) is a general hospital in Korea that developed an EMR system for outpatients from 2006 to 2008. This study measured the total costs and benefits during an 8-year period after EMR adoption. The costs include the system costs of building the EMR and the costs incurred in smoothing its adoption. The benefits included cost reductions after its adoption and additional revenues from both remodeling of paper-chart storage areas and medical transcriptionists' contribution. The measured amounts were discounted by SMC's expected interest rate to calculate the net present value (NPV), benefit-cost ratio (BCR), and discounted payback period (DPP). During the analysis period, the cumulative NPV and the BCR were US$3,617 thousand and 1.23, respectively. The DPP was about 6.18 years. Although the adoption of an EMR resulted in overall growth in administrative costs, it is cost-effective since the cumulative NPV was positive. The positive NPV was attributed to both cost reductions and additional revenues. EMR adoption is not so attractive to management in that the DPP is longer than 5 years at 6.18 and the BCR is near 1 at 1.23. However, an EMR is a worthwhile investment, seeing that this study did not include any qualitative benefits and that the paper-chart system was cost-centric.

    Full Text Available Aim. To study the effects of antihypertensive therapy based on consideration of individual heart rhythm variability (HRV on left ventricular hypertrophy (LVH in hypertensive elderly patients.Material and methods. 60 hypertensive elderly patients with LVH were included in the study. They were split in two groups (30 people in each one. Patients of the group-I had common antihypertensive therapy. Patients of group-II received medications prescribed with consideration of individual heart rate variability. Holter monitoring with analysis of HRV, 24-hour blood pressure monitoring and ultrasonography were conducted initially and 18 months after treatment beginning.Results. BP control was reached in the majority of patients of both groups. The patients of group-II in comparison with patients of group-I had reduction of low- high frequency power ratio (LF/HF and higher rate of LVH reduction. Relationship between LVH dynamics and ratio LF/HF was found.Conclusion. Arterial hypertension therapy considering individual HRV contributes in LVH reduction in elderly patients.

    A primary objective of the recommendations of the International Committee on Radiological Protection Publication 26 is to insure that no source of radiation exposure is unjustified in relation to its benefits. This objective is consistent with goals of the Radiation Safety Committee and Institutional Review Board at medical centers where research may involve radiation exposure of human subjects. The effective dose equivalent concept facilitates evaluation of risk by those who have little or no knowledge of quantities or biological effects of radiation. This paper presents effective dose equivalent data used by radiation workers and those who evaluate human research protocols as these data relate to personal dosimeter reading, entrance skin exposure, and target organ dose. The benefits of using effective dose equivalent to evaluate risk of medical radiation environments and research protocols are also described

  12. Antihypertensive treatment and stroke prevention: are angiotensin receptor blockers superior to other antihypertensive agents?

    Science.gov (United States)

    Armario, Pedro; de la Sierra, Alejandro

    2009-06-01

    Stroke remains a common vascular event with high mortality and morbidity. After heart disease, stroke is the second leading cause of death worldwide in adult persons. Silent or subclinical stroke is likely to occur with even greater frequency than clinical stroke and increases the risk of subsequent cerebrovascular events. Hypertension is by far the single most important controllable risk factor for stroke. The relationship between blood pressure (BP) and stroke mortality is strong, linear, and continuous in subjects with levels of BP higher than 115/75 mm Hg. Blood pressure reduction by antihypertensive treatment is clearly efficacious in the prevention of stroke (both primary and secondary). Although meta-analyses suggest that BP reduction, per se, is the most important determinant for stroke risk reduction, the question is if specific classes of antihypertensive drugs offer special protection against stroke is still controversial. Some studies have suggested that angiotensin receptors blockers (ARBs) appear to offer additional protection against stroke. This has been hypothesized in studies in hypertensives, such as LIFE and SCOPE, and especially in the only comparative trial focused on secondary stroke prevention. In the MOSES trial, the comparison of eprosartan versus nitrendipine in patients with a previous stroke resulted, despite a similar BP reduction, in a significant reduction in the primary composite endpoint of total mortality plus cardiovascular and cerebrovascular events, including recurrent events. These results may suggest a blood pressure-independent effect of ARBs, which can be mediated through several mechanisms, including their ability to counteract other markers of target organ damage, but also through a direct neuroprotective effect.

    This study investigated the in vivo antihypertensive activity of three novel peptides identified in the in vitro digest of pork meat. These peptides were RPR, KAPVA and PTPVP and all of them showed significant antihypertensive activity after oral administration to spontaneously hypertensive rats, RPR being the peptide with the greatest in vivo activity. To our knowledge, this is the first report showing the in vivo antihypertensive action of the three peptides from nebulin (RPR) and titin (KAPVA and PTPVP), thus confirming their reported in vitro angiotensin I-converting enzyme (ACE) inhibitory activity. These findings suggest that pork meat could constitute a source of bioactive constituents that could be utilized in functional foods or nutraceuticals. Copyright © 2012 Elsevier Ltd.

    An information leaflet for concerned patients is in preparation, which attempts to explain the risks and benefits of diagnostic medical exposures in terms suitable for the layman. In view of the wide variability in patient doses for the same examination and the considerable uncertainties in radiation risk coefficients, x-ray examinations have been divided into just four broad categories each spanning a factor of 10 in risk. The doses are put into perspective by comparison with those from natural background radiation. Sufficient quantitative information on the approximate level of the risks for some common diagnostic procedures is provided to allow patients to make an informed decision on whether the benefits, as described by the referring clinician, outweigh the radiation risks.

    2010-06-09

    A set of eight lactoferricin B (LfcinB)-derived peptides was examined for inhibitory effects on angiotensin I-converting enzyme (ACE) activity and ACE-dependent vasoconstriction, and their hypotensive effect in spontaneously hypertensive rats (SHR). Peptides were derived from different elongations both at the C-terminal and N-terminal ends of the representative peptide LfcinB(20-25), which is known as the LfcinB antimicrobial core. All of the eight LfcinB-derived peptides showed in vitro inhibitory effects on ACE activity with different IC(50) values. Moreover, seven of them showed ex vivo inhibitory effects on ACE-dependent vasoconstriction. No clear correlation between in vitro and ex vivo inhibitory effects was found. Only LfcinB(20-25) and one of its fragments, F1, generated after a simulated gastrointestinal digestion, showed significant antihypertensive effects in SHR after oral administration. Remarkably, F1 did not show any effect on ACE-dependent vasoconstriction in contrast to the inhibitory effect showed by LfcinB(20-25). In conclusion, two LfcinB-derived peptides lower blood pressure and exhibit potential as orally effective antihypertensive compounds, yet a complete elucidation of the mechanism(s) involved deserves further ongoing research.

    An easy-to-administer tool for predicting response to antipsychotic treatment could improve the acute management of patients with schizophrenia. We assessed whether a patient's perception of medication benefit early in treatment could predict subsequent response or nonresponse to continued use of the same treatment. This post hoc analysis used data from a randomized, open-label trial of antipsychotics for treatment of schizophrenia in which attitudes about medication adherence were assessed after two weeks of antipsychotic treatment using the Rating of Medication Influences (ROMI) scale. The analysis included 439 patients who had Positive and Negative Syndrome Scale (PANSS) and ROMI scale data at Weeks 2 and 8. Scores on the ROMI subscale Perceived Medication Benefit factor were used to predict subsequent antipsychotic response at Week 8, defined as a .20% reduction from baseline on the PANSS. Logistic regression was used to identify a cut-off score for the Perceived Medication Benefit factor that could accurately identify antipsychotic responders vs. nonresponders at Week 8. A score of .2.75 (equal to a mean subscale score of .11.00) on the ROMI scale Perceived Medication Benefit factor at Week 2 predicted response at Week 8 with high specificity (72%) and negative predictive value (70%), moderate sensitivity (44%) and positive predictive value (47%), and with a 38% misclassification rate. A brief assessment of the patient's perception of medication benefit at two weeks into treatment appears to be a good predictor of subsequent response and nonresponse after eight weeks of treatment with the same antipsychotic.

    Medical Tourism’ – the phenomenon of people travelling abroad to access medical treatment - has received increasing attention in academic and popular media. This paper reports findings from a study examining effect of inbound and outbound medical tourism on the UK NHS, by estimating volume of medical tourism and associated costs and benefits. A mixed methods study it includes analysis of the UK International Passenger Survey (IPS); interviews with 77 returning UK medical tourists, 63 policymakers, NHS managers and medical tourism industry actors policymakers, and a review of published literature. These informed costing of three types of treatments for which patients commonly travel abroad: fertility treatment, cosmetic and bariatric surgery. Costing of inbound tourism relied on data obtained through 28 Freedom-of-Information requests to NHS Foundation Trusts. Findings demonstrate that contrary to some popular media reports, far from being a net importer of patients, the UK is now a clear net exporter of medical travellers. In 2010, an estimated 63,000 UK residents travelled for treatment, while around 52,000 patients sought treatment in the UK. Inbound medical tourists treated as private patients within NHS facilities may be especially profitable when compared to UK private patients, yielding close to a quarter of revenue from only 7% of volume in the data examined. Costs arise where patients travel abroad and return with complications. Analysis also indicates possible savings especially in future health care and social costs averted. These are likely to be specific to procedures and conditions treated. UK medical tourism is a growing phenomenon that presents risks and opportunities to the NHS. To fully understand its implications and guide policy on issues such as NHS global activities and patient safety will require investment in further research and monitoring. Results point to likely impact of medical tourism in other universal public health systems

    Full Text Available Introduction: Hypertensive emergency has a high mortality risk and the treatment goal is to quickly lower blood pressure with intravenous (IV medications. Characteristics that are associated with non-response to IV antihypertensives have not been identified. The objective is to identify patient characteristics associated with resistance to IV antihypertensives. Methods: This was a subanalysis of patients enrolled in the previously described comparative effectiveness trial of IV nicardipine vs. labetalol use in the emergency department (CLUE study, a randomized trial of nicardipine vs. labetalol. Non-responders were defined as those patients who did not achieve target systolic blood pressure (SBP, as set by the treating physician, within thirty minutes of IV antihypertensive medication, +/- 20mmHg. Stepwise logistic regression was used to identify covariates associated with the measurement outcomes. Results: CLUE enrolled 226 patients, 52.7% female, 76.4% black, mean age of 52.6±14.6 years, of whom 110 were treated with nicardipine and 116 with labetalol. The median (IQR initial systolic blood pressure was 211mmHg (198, 226, 210 (200, 230, and 211mmHg (198, 226, for the total, non-responder, and responder cohorts, respectively (p-value=0.65, 95% CI [-5.8-11.3]. Twenty-nine were non-responders, 9 in the nicardipine and 20 in the labetalol group. In univariate analysis, several symptoms suggestive of end organ damage were associated with non-response. After multiple variable logistic regression (AUC = 0.72, treatment with labetalol (OR 2.7, 95% CI [1.1-6.7], history of stroke (OR 5.4, 95% CI [1.6-18.5], and being male (OR 3.3, 95% CI [1.4-8.1] were associated with failure to achieve target blood pressure. Conclusion: Male gender and history of previous stroke are associated with difficult to control blood pressure. [West J Emerg Med. 2015;16(2:276–283.

    Full Text Available Background Informatics tools may help support hypertension management.Objective To design, implement and evaluate a web-based system for patient anti-hypertensive medication self-titration.Methods Study stages included: six focus groups (50 patients to identify barriers/facilitators to patient medication self-titration, software design informed by qualitative analysis of focus group responses and a six-month single-arm pilot study (20 patients to assess implementation feasibility.Results Focus groups emphasised patient need to feel confident that their own primary care providers were directly involved and approved of the titration protocol. Physicians required 3.3 ± 2.8 minutes/patient to create individualised six-step medication pathways for once-monthly blood pressure evaluations. Pilot participants (mean age of 51.5 ± 11 years, 45% women, mean baseline blood pressure 139/84 ± 12.2/7.5 mmHg had five medication increases, two non-adherence self-reports, 52months not requiring medication changes, 24 skipped months and 17 months with no evaluations due to technical issues. Four pilot patients dropped out before study completion. From baseline to study completion, blood pressure decreased among the 16 patients remaining in the study (8.0/4.7 mmHg, p = 0.03 for both systolic and diastolic pressures.Conclusions Lessons learned included the benefit of qualitative patient analysis prior to system development and the feasibility of physicians designing individual treatment pathways. Any potential clinical benefits were offset by technical problems, the tendency for patients to skip their monthly self-evaluations and drop outs. To be more widely adopted such systems must effectively generalise to a wider range of patients and be integrated into clinical workflow.

    By eliminating glucose in the urine, the sodium-glucose-linked cotransporter-2 (SGLT2) inhibitors act as osmotic diuretics to lower blood pressure in addition to reducing plasma glucose and assisting with weight loss. While not approved as antihypertensive agents, the ability of this new class of antihyperglycemic agents to lower blood pressure is not insubstantial, and while not used primarily for this indication, they may assist diabetic individuals in attaining currently recommended blood pressure targets. In addition to lowering systemic pressure, preclinical and exploratory human studies suggest that SGLT2 inhibitors may also lower intraglomerular pressure, potentially reducing the rate of GFR decline in patients with diabetic nephropathy. However, given the lack of clinically meaningful endpoint data, the use of SGLT2 inhibitors, primarily, as either antihypertensive or renoprotective agents would, at present, be premature. Fortunately, further insight will be garnered from large, randomized controlled trials that will assess the effects of various SGLT2 inhibitors on cardiovascular and renal outcomes.

    The DENERHTN trial (Renal Denervation for Hypertension) confirmed the blood pressure-lowering efficacy of renal denervation added to a standardized stepped-care antihypertensive treatment for resistant hypertension at 6 months. We report the influence of adherence to antihypertensive treatment on blood pressure control. One hundred six patients with hypertension resistant to 4 weeks of treatment with indapamide 1.5 mg/d, ramipril 10 mg/d (or irbesartan 300 mg/d), and amlodipine 10 mg/d were randomly assigned to renal denervation plus standardized stepped-care antihypertensive treatment, or the same antihypertensive treatment alone. For standardized stepped-care antihypertensive treatment, spironolactone 25 mg/d, bisoprolol 10 mg/d, prazosin 5 mg/d, and rilmenidine 1 mg/d were sequentially added at monthly visits if home blood pressure was ≥135/85 mm Hg after randomization. We assessed adherence to antihypertensive treatment at 6 months by drug screening in urine/plasma samples from 85 patients. The numbers of fully adherent (20/40 versus 21/45), partially nonadherent (13/40 versus 20/45), or completely nonadherent patients (7/40 versus 4/45) to antihypertensive treatment were not different in the renal denervation and the control groups, respectively (P=0.3605). The difference in the change in daytime ambulatory systolic blood pressure from baseline to 6 months between the 2 groups was -6.7 mm Hg (P=0.0461) in fully adherent and -7.8 mm Hg (P=0.0996) in nonadherent (partially nonadherent plus completely nonadherent) patients. The between-patient variability of daytime ambulatory systolic blood pressure was greater for nonadherent than for fully adherent patients. In the DENERHTN trial, the prevalence of nonadherence to antihypertensive drugs at 6 months was high (≈50%) but not different in the renal denervation and control groups. Regardless of adherence to treatment, renal denervation plus standardized stepped-care antihypertensive treatment resulted in

    Full Text Available Adlay (Coix larchryma-jobi L. was the commonly used Traditional Chinese Medicine (TCM with high content of seed storage protein. The hydrolyzed bioactive oligopeptides of adlay have been proven to be anti-hypertensive effective components. However, the structures and anti-hypertensive mechanism of bioactive oligopeptides from adlay were not clear. To discover the definite anti-hypertensive oligopeptides from adlay, in silico proteolysis and virtual screening were implemented to obtain potential oligopeptides, which were further identified by biochemistry assay and molecular dynamics simulation. In this paper, ten sequences of adlay prolamins were collected and in silico hydrolyzed to construct the oligopeptide library with 134 oligopeptides. This library was reverse screened by anti-hypertensive pharmacophore database, which was constructed by our research team and contained ten anti-hypertensive targets. Angiotensin-I converting enzyme (ACE was identified as the main potential target for the anti-hypertensive activity of adlay oligopeptides. Three crystal structures of ACE were utilized for docking studies and 19 oligopeptides were finally identified with potential ACE inhibitory activity. According to mapping features and evaluation indexes of pharmacophore and docking, three oligopeptides were selected for biochemistry assay. An oligopeptide sequence, NPATY (IC50 = 61.88 ± 2.77 µM, was identified as the ACE inhibitor by reverse-phase high performance liquid chromatography (RP-HPLC assay. Molecular dynamics simulation of NPATY was further utilized to analyze interactive bonds and key residues. ALA354 was identified as a key residue of ACE inhibitors. Hydrophobic effect of VAL518 and electrostatic effects of HIS383, HIS387, HIS513 and Zn2+ were also regarded as playing a key role in inhibiting ACE activities. This study provides a research strategy to explore the pharmacological mechanism of Traditional Chinese Medicine (TCM proteins based on

Management of hypertension is generally based on office blood pressure since it is easy to determine. Since casual blood pressure readings in the office are influenced by various factors, they do not represent basal blood pressure. Dipping of the blood pressure in the night is a normal physiological change that can be blunted by cardiovascular risk factors and the severity of hypertension. Nondipping pattern is associated with disease severity, left ventricular hypertrophy, increased proteinuria, secondary forms of hypertension, increased insulin resistance, and increased fibrinogen level. Long-term observational studies have documented increased cardiovascular events in patients with nondipping patterns. Nocturnal dipping can be improved by administering the antihypertensive medications in the night. Long-term clinical trials have shown that cardiovascular events can be reduced by achieving better dipping patterns by administering medications during the night. Identifying the dipping pattern is useful for decisions to investigate for secondary causes, initiating treatment, necessity of chronotherapy, withdrawal or reduction of unnecessary medications, and monitoring after treatment initiation. Use of this concept at the primary care level has been limited because 24-hour ambulatory blood pressure monitoring has been the only method

    The Necessity-Concerns Framework (NCF) is a multidimensional theory describing the relationship between patients' positive and negative evaluations of their medication which interplay to influence adherence. Most studies evaluating the NCF have failed to account for the multidimensional nature of the theory, placing the separate dimensions of medication "necessity beliefs" and "concerns" onto a single dimension (e.g., the Beliefs about Medicines Questionnaire-difference score model). To assess the multidimensional effect of patient medication beliefs (concerns and necessity beliefs) on medication adherence using polynomial regression with response surface analysis. Community-dwelling older adults >65 years (n = 1,211) presenting their own prescription for antihypertensive medication to 106 community pharmacies in the Republic of Ireland rated their concerns and necessity beliefs to antihypertensive medications at baseline and their adherence to antihypertensive medication at 12 months via structured telephone interview. Confirmatory polynomial regression found the difference-score model to be inaccurate; subsequent exploratory analysis identified a quadratic model to be the best-fitting polynomial model. Adherence was lowest among those with strong medication concerns and weak necessity beliefs, and adherence was greatest for those with weak concerns and strong necessity beliefs (slope β = -0.77, pnecessity beliefs had lower adherence than those with simultaneously low concerns and necessity beliefs (slope β = -0.36, p = .004; curvature β = -0.25, p = .003). The difference-score model fails to account for the potential nonreciprocal effects. Results extend evidence supporting the use of polynomial regression to assess the multidimensional effect of medication beliefs on adherence.

    A cross-sectional study was conducted to determine the prevalence and predictors of adherence to modern antihypertensive pharmacotherapy among slum dwellers in Kolkata, India. Prevalence of adherence based on patient self-reports of consuming ≥80% of the prescribed medications over a recall period of 1 week was found to be 73% (95% confidence interval = 68%-78%). Compared with their counterparts, the following patients were more likely to be adherent to treatment: patients hypertensive for ≥5 years (2.98 times), those whose hypertension was detected during checkups for conditions related to hypertension (2.35 times), those living with ≤4 family members (2.01 times), those with family income of ≥3000 rupees (2.56 times), those who were getting free drugs (4.16 times), patients perceiving current blood pressure to be under control (2.23 times), and those satisfied with current treatment (3.77). Those adherent to their prescribed medications were 1.71 times more likely to achieve adequate control of hypertension compared with those who were not adherent. © 2011 APJPH.

    Full Text Available Cosmos caudatus is widely used as a traditional medicine in Southeast Asia. C. caudatus has been reported as a rich source of bioactive compounds such as ascorbic acid, quercetin, and chlorogenic acid. Studies have shown that C. caudatus exhibits high anti-oxidant capacity and various medicinal properties, including anti-diabetic activity, anti-hypertensive properties, anti-inflammatory responses, bone-protective effect, and anti-microbial activity. This review aims to present the potential medicinal benefits of C. caudatus from the available scientific literature. We searched PubMed and ScienceDirect database for articles published from 1995 to January 2015. Overall, 15 articles related to C. caudatus and its medicinal benefits are reviewed. All these studies demonstrated that C. caudatus is effective, having demonstrated its anti-diabetic, anti-hypertensive, anti-inflammatory, bone-protective, anti-microbial, and anti-fungal activity in both in vitro and animal studies. None of the studies showed any negative effect of C. caudatus related to medicinal use. Currently available evidence suggests that C. caudatus has beneficial effects such as reducing blood glucose, reducing blood pressure, promoting healthy bone formation, and demonstrating anti-inflammatory and anti-microbial properties. However, human clinical trial is warranted.

  16. Mechanisms of remodelling of small arteries, antihypertensive therapy and the immune system in hypertension.

    Schiffrin, Ernesto L

    2015-12-04

    This review summarizes my lecture for the 2015 Distinguished Scientist Award from the Canadian Society of Clinical Investigation, and is based mainly on studies in my laboratory on the mechanisms of remodelling of small arteries in experimental animal and human hypertension and on treatments that lower blood pressure and improve structure and function of resistance vessels. Small resistance arteries undergo either inward eutrophic or hypertrophic remodelling, which raises blood pressure and impairs tissue perfusion. These vascular changes are corrected by some antihypertensive drugs, which may lead to improved outcomes. Vasoconstriction, growth, oxidative stress and inflammation are some of the mechanisms, within the vascular wall, that can be beneficially affected by antihypertensive agents. These antihypertensive-sensitive mechanisms are reviewed in this review, together with the inflammatory and immune mechanisms that may participate in hypertension and associated cardiovascular injury. Molecular studies, based on this research, will hopefully identify novel diagnostic and therapeutic targets, which will improve our ability to prevent and treat hypertension and cardiovascular disease.

    The opinion of experts (different specialties) on the triple fixed-dose antihypertensive therapy in clinical practice may differ. Online questionnaire with controversial aspects of the triple therapy answered by panel of experts in hypertension (HT) using two-round modified Delphi method. The questionnaire was completed by 158 experts: Internal Medicine (49), Nephrology (26), Cardiology (83). Consensus was reached (agreement) on 27/45 items (60%); 7 items showed differences statistically significant. Consensus was reached regarding: Predictive factors in the need for combination therapy and its efficacy vs. increasing the dose of a pretreatment, and advantage of triple therapy (prescription/adherence/cost/pressure control) vs. free combination. This consensus provides an overview of the clinical use of triple therapy in moderate-severe and resistant/difficult to control HT. Copyright © 2016 SEH-LELHA. Publicado por Elsevier España, S.L.U.

  18. L-type Ca²⁺ channel blockade with antihypertensive medication disrupts VTA synaptic plasticity and drug-associated contextual memory.

    Drug addiction is driven, in part, by powerful and enduring memories of sensory cues associated with drug intake. As such, relapse to drug use during abstinence is frequently triggered by an encounter with drug-associated cues, including the drug itself. L-type Ca(2+) channels (LTCCs) are known to regulate different forms of synaptic plasticity, the major neural substrate for learning and memory, in various brain areas. Long-term potentiation (LTP) of NMDA receptor (NMDAR)-mediated glutamatergic transmission in the ventral tegmental area (VTA) may contribute to the increased motivational valence of drug-associated cues triggering relapse. In this study, using rat brain slices, we found that isradipine, a general LTCC antagonist used as antihypertensive medication, not only blocks the induction of NMDAR LTP but also promotes the reversal of previously induced LTP in the VTA. In behaving rats, isradipine injected into the VTA suppressed the acquisition of cocaine-paired contextual cue memory assessed using a conditioned place preference (CPP) paradigm. Furthermore, administration of isradipine or a CaV1.3 subtype-selective LTCC antagonist (systemic or intra-VTA) before a single extinction or reinstatement session, while having no immediate effect at the time of administration, abolished previously acquired cocaine and alcohol (ethanol) CPP on subsequent days. Notably, CPP thus extinguished cannot be reinstated by drug re-exposure, even after 2 weeks of withdrawal. These results suggest that LTCC blockade during exposure to drug-associated cues may cause unlearning of the increased valence of those cues, presumably via reversal of glutamatergic synaptic plasticity in the VTA.

    Urtica dioica has traditionally been used in the management of cardiovascular disorders especially hypertension. The aim of this study was to explore pharmacological base of its use in hypertension. Crude methanolic extract of U. dioica (Ud.Cr) and its fractions (Ud.EtAc, Ud.nHex, Ud.Chl and Ud.Aq) were tested in vivo on normotensive and hypertensive rats under anesthesia for blood pressure lowering effect. In-vitro experiments on rat and rabbit aortae were employed to probe the vasorelaxation mechanism(s). The responses were measured using pressure and force transducers connected to PowerLab Data Acquisition System. Ud.Cr and fractions were found more effective antihypertensive in hypertensive rats than normotensive with remarkable potency exhibited by the ethyl acetate fraction. The effect was same in the presence of atropine. In isolated rat aortic rings, Ud.Cr and all its fractions exhibited L-NAME sensitive endothelium-dependent vasodilator effect and also inhibit K(+) (80 mM)-induced pre-contractions. In isolated rabbit thoracic aortic rings Ud.Cr and its fractions induced relaxation with more potency against K(+) (80 mM) than phenylephrine (1 µM) like verapamil, showing Ud.EtAc fraction the most potent one. Pre-incubation of aortic rings with Ud.Cr and its fractions exhibited Ca(2+) channel blocking activity comparable with verapamil by shifting Ca(2+) concentration response curves to the right. Ud.Cr and its fractions also ablated the intracellular Ca(2+) release by suppressing PE peak formation in Ca(2+) free medium. When tested on basal tension, the crude extract and all fractions were devoid of any vasoconstrictor effect. These data indicate that crude methanolic extract and its fractions possess antihypertensive effect. Identification of NO-mediated vasorelaxation and calcium channel blocking effects explain the antihypertensive potential of U. dioica and provide a potential pharmacological base to its medicinal use in the management of hypertension.

    To estimate consumption of five subgroups of antihypertensive drugs by primary care areas and to analyze its variation. We performed an ecological, descriptive study of antihypertensive consumption in 239 primary care areas in the autonomous region of Valencia in 2005 followed by analysis of the variability observed. The 239 primary care areas were studied by descriptive analysis of dispensation [defined daily dose (DDD) per 1,000 inhabitants/day in pensioners (DDD/1000p/day) and in the active population (DDD/1000a/day)] and standardized consumption ratios. Small-area variation analysis was used to analyze the observed variability. Associations among dispensations of the distinct therapeutic subgroups were also analyzed. Overall antihypertensive use in the autonomous region of Valencia in 2005 was 235.6DDD/1000/day. This consumption was concentrated in pensioners (800DDD/1000p/day vs. 73DDD/1000a/day). Consumption of antihypertensive subgroups oscillated from 442DDD/1000p/day for drugs with action on the renin-angiotensin system to 32DDD/1000p/day for doxazosin. The active population showed similar patterns. Variation in consumption was moderate, with coefficients of variation from 0.20 to 0.40 (slightly greater for the active population). Associations among dispensations of the different therapeutic subgroups were strong. This study shows major variations in the overall consumption of antihypertensive drugs among primary care areas of the autonomous region of Valencia. These results suggest that variation may be associated with problems of underutilization in areas with lower consumption. Copyright © 2010 SESPAS. Published by Elsevier Espana. All rights reserved.

    Full Text Available The aging kidney manifests structural, functional as well as pharmacological changes, rendering elderly patients more susceptible to adverse environmental influences on their health, dehydration in particular.Higher temperature is associated with renal function impairment in patients 65 years and older who routinely take thiazide and/or ACE-inhibitors/ARBs.We obtained health data of patients older than 65 who were admitted to a large tertiary center during the years 2006-2011, with a previous diagnosis of hypertension, and treated with thiazide, ACE-inhibitors/ARBs or both. We collected environmental data of daily temperature, available from collaborative public and governmental institutions. In order to estimate the effect of daily temperature on renal function we performed linear mixed models, separately for each treatment group and creatinine change during hospital admission.We identified 26,286 admissions for 14, 268 patients with a mean age of 75.6 (±6.9 years, of whom 53.6% were men. Increment in daily temperature on admission of 5°C had significant effect on creatinine increase in the no treatment (baseline creatinine adjusted 0.824 mg/dL, % change 1.212, % change 95% C.I 0.082-2.354 and dual treatment groups (baseline creatinine adjusted 1.032mg/dL, % change 3.440, % change 95% C.I 1.227-5.700. Sub-analysis stratified by advanced age, chronic kidney disease and primary diagnosis on hospital admission, revealed a significant association within patients admitted due to acute infection and treated with dual therapy.Whereas previous studies analyzed sporadic climate effects during heat waves and/or excluded older population taking anti-hypertensive medications, the present study is novel by showing a durable association of temperature and decreased renal function specifically in elderly patients taking anti-hypertensive medications.

    Family and intergenerational perspectives might contribute to a better understanding of why young people in many European countries experience work impairment and end up being dependent on public benefits for life sustenance. The aim of this cohort study was to explore the relationship between the receipt of medical benefits in parents and their young adult offspring and the contributions of family health and family socioeconomic status. Baseline information on the health of 7597 adolescents and their parents who participated in the HUNT Study 1995-1997 was linked to national registers to identify long-term receipt of medical benefits for parents (1992-1997) and adolescents as they entered adulthood (1998-2008). We used logistic regression to explore the association between parent and offspring receipt of medical benefits, adjusting for family health and socioeconomic status. Among adolescents, 13% received medical benefits from age 20-29. Adolescents whose parents had received medical benefits (26%) were more likely to receive such benefits themselves from age 20-29 compared with adolescents without benefit-receiving parents (age- and sex-adjusted odds ratio (OR) 2.16, 95 % confidence interval (CI) 1.86-2.49). Adjustment for family health reduced this estimate considerably (to OR 1.66, 95% CI 1.38-1.99), whereas adjustment for family socioeconomic status had less impact. Adolescents whose parents receive medical benefits enter adult working life with an elevated risk of health-related work exclusion. Family health vulnerability appears to be a key to understanding this association, suggesting that more attention to intergenerational continuities of health could be a way to prevent welfare dependence in future generations.

    Williams syndrome is caused by the deletion of 26 to 28 genes, including elastin, on human chromosome 7. Elastin insufficiency leads to the cardiovascular hallmarks of this condition, namely focal stenosis and hypertension. Extrapolation from the Eln(+/-) mouse suggests that affected people may also have stiff vasculature, a risk factor for stroke, myocardial infarction, and cardiac death. NCF1, one of the variably deleted Williams genes, is a component of the nicotinamide adenine dinucleotide phosphate (NADPH) oxidase complex and is involved in the generation of oxidative stress, making it an interesting candidate modifier for vascular stiffness. Using a case-control design, vascular stiffness was evaluated by pulse wave velocity in 77 Williams cases and matched controls. Cases had stiffer conducting vessels than controls (PWilliams syndrome. Pulse wave velocity increased with age at comparable rates in cases and controls, and although the degree of vascular stiffness varied, it was seen in both hypertensive and normotensive Williams participants. Use of antihypertensive medication and extension of the Williams deletion to include NCF1 were associated with protection from vascular stiffness. These findings demonstrate that vascular stiffness is a primary vascular phenotype in Williams syndrome and that treatment with antihypertensives or agents inhibiting oxidative stress may be important in managing patients with this condition, potentially even those who are not overtly hypertensive.

    To evaluate the evolution of consumption of antihypertensive drugs generic among 1991-2010, to assess the impacts after the institution of Mandatory Health Insurance and the marketing of generic drugs. We used sales data from the Moroccan subsidiary of IMS Health Intercontinental Marketing Service. Consumption of generic antihypertensive drugs increased from 0.08 to 10.65 DDD/1 000 inhabitants/day between 1991 and 2010. In 2010, generic of the calcium channel blockers (CCBs) represented 4.08 DDD/1 000 inhabitants/day (82.09%), followed by angiotensin converting enzyme inhibitors (ACEI) by 2.40 DDD/1 000 inhabitants/day (48.29%). The generics market of CCBs is the most dominant and represented in 2010, 79.21% in volume and 62.58% in value. In developing countries like Morocco, the generic drug is a key element for access to treatment especially for the poor population. © 2013 Société Française de Pharmacologie et de Thérapeutique.

    We investigated the association between antipsychotic medications and the risk of dental caries in patients with schizophrenia. We enroled a nationwide cohort of patients with newly diagnosed schizophrenia within 1 year of dental caries development. Exposure to antipsychotics and other medications was categorised according to their type and duration, and the association between exposure and dental caries was assessed through logistic regressions. Of the 3610 patients with newly diagnosed schizophrenia, 2149 (59.5%) exhibited an incidence of treated dental caries. Logistic regression analysis identified a younger age, female sex, high income, a 2-year history of dental caries, and exposure to first-generation antipsychotics, and antihypertensives as independent risk factors for treated dental caries in patients with schizophrenia. Hyposalivation, the adverse effect of first-generation antipsychotics and antihypertensives, was associated with an increased risk of treated dental caries. However, hypersalivation from first-generation antipsychotics for dental caries was associated with a protective factor. These findings suggest that clinicians should pay attention to the aforementioned risk factors for dental caries in patients with schizophrenia, particularly while prescribing first-generation antipsychotics and antihypertensives to such patients.

    The guidelines for the management of hypertension recommend the inclusion of diuretics, especially when three or more antihypertensive drugs are used. The present study investigated the current prescription status of antihypertensive drugs with a particular focus on the use of diuretics in a local district in Japan. Prescriptions, including antihypertensive drugs, were collected from a dispensing pharmacy of the Yahata Pharmacist Association, located in Kitakyushu City, in October 2014. Of the 10 585 prescriptions, calcium channel blockers (CCBs) were prescribed in 73.5%, followed by angiotensin II receptor blockers (ARB, 62.7%), diuretics (16.5%) and β-blockers (13.6%). The average number of drugs used was 1.80. The rates of prescription of diuretics for patients with one, two, three and four drugs were 0.6%, 13.1%, 55.2% and 82.6%, respectively. Diuretics were more frequently prescribed in elderly patients, and the prescription rate of doctors in hospitals was significantly higher than that of general practitioners (19.1% vs. 15.7%, Pdiuretics were prescribed combination tablets of hydrochlorothiazide with ARB, whereas trichlormethiazide (34.9%) and indapamide (19.8%) were used in other patients. Based on these findings, the use of diuretics remains limited, even among patients taking multiple antihypertensive drugs.

    Poor compliance with antihypertensive medications is one possible reason why its success in clinical trials has not been translated into everyday practice. In addition, medication noncompliance in elderly leads to increased hospitalizations, physician visits, and higher health care costs. The study assessed influence of illness perceptions and medications beliefs on medication compliance of elderly hypertensive cohorts. A cross-sectional survey research design, utilizing self-administered health surveys, was adapted to address key study objectives. Conceptualized associations among the study variables were explored to assess their individual as well as their collective impact on the medication compliance. A total of 78 (66%) study samples were found to be noncompliant with their medications. Analysis revealed that perceptions about illness and beliefs about medication jointly played a significant role in the prediction of medication compliance (F = 5.966, P compliance building in elderly populations having hypertension by incorporating the value and importance of patient perceptions of illness and medications in order to achieve desired patient outcomes.

    In the era of newly introduced hypertension guidelines recommending lower blood pressure (BP) targets for drug-treated hypertensives, the necessity for optimized management of hypertension becomes even more urgent. The concept of home BP-guided antihypertensive therapy is for long suggested as a simple and feasible approach to improve BP control rates and optimize the management of hypertension. Home BP-guided antihypertensive therapy is particularly applicable to hypertensives with chronic kidney disease (CKD) for several reasons including the following: (1) difficult-to-control BP and high BP variability in the CKD setting; (2) poor accuracy of office BP in determining hypertension control status and detecting "white-coat" and "masked" hypertension; (3) poor value of routine office BP recordings in predicting the longitudinal progression of target-organ damage; and (4) superiority of home BP over office BP recordings in prognosticating the risk of incident end-stage renal disease or death. The concept of home BP-guided antihypertensive therapy is even more relevant for those on hemodialysis, given the high intradialytic and interdialytic BP variability and poor value of conventional peridialytic BP recordings in estimating the actual BP load recorded outside of dialysis with the use of home or ambulatory BP monitoring. Randomized trials comparing home BP-guided antihypertensive therapy versus usual care are warranted to prove the feasibility and effectiveness of this therapeutic approach and convince clinicians for using home BP monitoring as the standard of care when managing hypertension, particularly in people with CKD or end-stage renal disease.

    The objective of residency training is to produce physicians who can function independently within their chosen subspecialty and practice environment. Skills in the business of medicine, such as clinical billing, are widely applicable in academic and private practices but are not commonly addressed during formal medical education. Residency and fellowship training include limited exposure to medical billing, but our academic department's performance of these skills was inadequate: in 56% of trainee-generated outpatient notes, documentation was insufficient to sustain the chosen billing level. We developed a curriculum to improve the accuracy of documentation and coding and introduced practice changes to address our largest sources of error. In parallel, we developed tools that increased the speed and efficiency of documentation. Over 15 months, we progressively eliminated note devaluation, increased the mean level billed by trainees to nearly match that of attending physicians, and increased outpatient revenue by $34,313/trainee/year. Our experience suggests that inclusion of billing education topics into the formal medical curriculum benefits both academic medical centers and trainees. © 2014 American Academy of Neurology.

    Compliance with treatment regimens is a continuing challenge for chronic dialysis patients and their medical caregivers. Poor patient adherence to prescribed medications can adversely affect treatment outcome. In this pre- versus post-intervention study, 89 chronic dialysis patients [75 hemodialysis (HD), 14 continuous ambulatory peritoneal dialysis (CAPD); mean age 62.7 +/- 12.39 years, 34 females] responded to a written questionnaire designed to assess knowledge about and compliance with 5 groups of prescribed medications: metabolic drugs, antihypertensives, cardiac-supporting agents, peptic disease therapy and hematological replacement therapy. Mode of intake, storage, means of supply and source of information for each class of drug were also assessed. Patients then received both oral and written instructions regarding their prescribed medications (intervention). This information was repeated 3 months later. Six months after the intervention, patients were re-administered the questionnaires. Response to the questionnaires and laboratory data were compared prior to and following the intervention. Overall, compliance with prescribed medications significantly improved following the intervention, from 89 to 95.7%, p = 0.0007. This relative improvement was greater in HD than CAPD patients (27 vs. 2%, p dialysis vintage. Compared to baseline values, post-intervention blood hemoglobin, hematocrit, mean corpuscular volume, ferritin and Ca levels were significantly improved. Dialysis patients appear to benefit from receiving comprehensive guidance about medications, in terms of compliance with medications and blood chemistry and hematology measures. (c) 2009 S.

Group 1 consisted of 67 patients with non-diabetic CKD. Group 2 consisted of 54 CKD patients with DN. All patients had arterial hypertension grade 1 or 2 (ESH/ESC, 2013. All patients underwent clinical examination, echocardiography; GFR was estimated by the Cockcroft-Gault formula. Stages of chronic kidney disease (CKD were determined according to the KDOQI 2002 classification. Eprosartan and lercanidipine were prescribed to patients after one week of lavage from previous antihypertensive therapy. This 6-month follow-up study compared the effectiveness of two courses of treatment. Results: LVH was observed in all CKD patients regardless of the presence or absence of DN. Eprosartan and lercanidipine showed the high antihypertensive efficacy expressing a reliable decrease in absolute values of SBP and DBP. In CKD patients with DN, on the background of a comparable antihypertensive effect, eprosartan, in comparison with lercanidipine, showed a more pronounced effect on the LV echocardiographic parameters associated with LVH regression.

    Hypertension is one of the leading causes of cardiovascular morbidity and mortality and more than a half of all health insurance expenditures for reimbursed medicines are allocated to antihypertensive drugs in Serbia. The aim of this study was to identify the antihypertensive drug utilization patterns among hypertensive outpatients in the city of Novi Sad, Serbia, determine the adherence to clinical guidelines and address the economic aspects of current prescribing practices. This retrospective observational study was conducted in Novi Sad over a period of six months. The data on the number of packages, size their, and retail price of antihypertensives issued on prescription in outpatients with the diagnosis of essential arterial hypertension was collected from all state-owned pharmacies in Novi Sad. Drug consumption was analyzed using the Anatomical Therapeutic Chemical (ATC)/ defined daily dose (DDD) methodology. Total consumption of antihypertensives issued on prescription over a 6-month period in the city of Novi sad, Serbia was 283.48 DDD per 1,000 inhabitans per day (DID). Angiotensin converting enzyme inhibitors (ACEi) were most commonly prescribed drugs, and were used 3 times more often than calcium channel blockers and 5 times more than beta-blockers. The consumption of diuretics and angiotensin receptor antagonists was low within all the groups of outpatients. Both national and international guidelines state superiority and effectiveness of diuretics in treatment of hypertension in the elderly, but their consumption was unreasonable low despite the fact that over 70% of all antihypertensive drugs in the city of Novi Sad were dispensed in people aged > 60. The use of more expensive ACEi was observed despite the guidelines deeming all the drugs of this class equally effective in treatment of hypertension. Large differences in utilization of different groups of antihypertensive agents were noted in this study. Underutilization of valuable, efficacious, and

    The present review focuses in the hypertension-associated changes in the microbiota and the current insights regarding the impact of probiotics on blood pressure in animal models and in human hypertensive patients. Gut dysbiosis in hypertension is characterized by (i) the gut microbioma that is less diverse and less rich with an increased Firmicutes/Bacteroidetes ratio and (ii) a decrease in acetate- and butyrate-producing bacteria and an increase in lactate-producing bacterial populations. The meta-analysis of the human studies supports that supplementation with probiotics reduces blood pressure. The mechanism of this antihypertensive effect of probiotics and its protective effect on endothelial function has not been fully elucidated. Further investigations are needed to clarify if the effects of probiotic bacteria result from the changes in the gut microbiota and its metabolic by-products; the restoration of the gut barrier function; and the effects on endotoxemia, inflammation, and renal sympathetic nerve activity.

    Psychotropic medications are commonly used for depressive symptoms among people living with HIV/AIDS. We examined the relationships between adherence to psychotropic medications, depressive symptoms, and antiretroviral adherence. We assessed depressive symptoms among 324 people living with HIV/AIDS across a 3-month period (70% men; mean age 45 years; 90% African-American). Psychotropic and antiretroviral adherence was assessed using monthly, unannounced telephone pill counts. Multiple-regression and mediation analyses were utilized to examine associations under investigation. Greater depressive symptoms were associated with lower antiretroviral and psychotropic medication adherence. Greater adherence to psychotropic medications regardless of medication class was positively related to higher antiretroviral adherence. Greater adherence to psychotropic medications also significantly mediated the association between depressive symptoms and antiretroviral adherence. This study demonstrates the benefits of adherence to psychotropic medications on both depressive symptoms and antiretroviral adherence. Future work examining psychotropic medication adherence on disease outcomes in people living with HIV/AIDS is warranted.

    The aim of this study was to evaluate the modifications of high sensitivity C-reactive protein (CRP) with antihypertensive and statin treatment in a hypertensive population with a wide range of coronary risks (CR). Retrospective follow-up study in 665 hypertensive patients: 556 (52% male) without dyslipidemia and CR (Framingham at 10 years) of 8.3 (7.6) as a control group (C) and 109 (61% male) with dyslipidemia and CR of 13.1 (8.8) who were treated with statins (T). Statins treatment was established according to NCEP-ATP-III. In both groups, the antihypertensive treatment was optimized in order to achieve blood pressure (BP) control (< 140/90 mmHg). A lipid profile and high sensitivity CRP (analyzed by nephelometry) was performed at the beginning and at the end of follow up [14.3 (3.6) months]. CRP levels were reduced in the T group -0.17 (0.2) mg/L vs. 0.14 (0.09) mg/L (p = 0.003, Mann-Whitney) in C. The lessening of CRP was not related to the reduction of lipids levels: total cholesterol (r = 0.06; p = 0.49), LDL-C (r = 0.11; p = 0.24), triglycerides (r = -0.02; p = 0.81) (Spearman), or to the reduction of systolic BP (r = -0.07; p = 0.44) and diastolic BP (r = -0.121; p = 0.21). The T group was treated with more antihypertensive drugs than C (2.2 [2.3] vs. 2.5 [1.2]; p = 0.02). Patients treated with ECA inhibitors or angiotensin II antagonist showed a tendency to decreasing the CRP levels more (p = 0.08). In hypertensive populations, statins induce a reduction of CRP levels. The reduction is not related to the lowering of lipids levels or BP values. The effect of statins on the reduction of CRP in hypertensive patients is not related to the lowering of lipids or BP.

    Sleep apnea/hypopnea disorders include centrally originated diseases and obstructive sleep apnea (OSA). This last condition is renowned as a frequent secondary cause of hypertension (HT). The mechanisms involved in the pathogenesis of HT can be summarized in relation to two main pathways: sympathetic nervous system stimulation mediated mainly by activation of carotid body (CB) chemoreflexes and/or asphyxia, and, by no means the least important, the systemic effects of chronic intermittent hypoxia (CIH). The use of animal models has revealed that CIH is the critical stimulus underlying sympathetic activity and hypertension, and that this effect requires the presence of functional arterial chemoreceptors, which are hyperactive in CIH. These models of CIH mimic the HT observed in humans and allow the study of CIH independently without the mechanical obstruction component. The effect of continuous positive airway pressure (CPAP), the gold standard treatment for OSA patients, to reduce blood pressure seems to be modest and concomitant antihypertensive therapy is still required. We focus this review on the efficacy of pharmacological interventions to revert HT associated with CIH conditions in both animal models and humans. First, we explore the experimental animal models, developed to mimic HT related to CIH, which have been used to investigate the effect of antihypertensive drugs (AHDs). Second, we review what is known about drug efficacy to reverse HT induced by CIH in animals. Moreover, findings in humans with OSA are cited to demonstrate the lack of strong evidence for the establishment of a first-line antihypertensive regimen for these patients. Indeed, specific therapeutic guidelines for the pharmacological treatment of HT in these patients are still lacking. Finally, we discuss the future perspectives concerning the non-pharmacological and pharmacological management of this particular type of HT. PMID:25295010

    Whether changes over time of urinary albumin excretion have prognostic value is a matter of discussion. The objective was to assess the prognostic value of changes in urinary albumin excretion over time in cardiovascular risk during antihypertensive treatment. Follow-up study of 2835 hypertensives in the absence of previous cardiovascular disease (mean age 55 years, 47% men, BP 138/80 mm Hg, 19.1% diabetics, and calibrated systemic coronary risk estimation 5 or >10.6%). Usual-care of antihypertensive treatment was implemented to maintain blood pressure<140/90 mm Hg. Urinary albumin excretion was assessed yearly, and the values were expressed as the creatinine ratio. Incidence of cardiovascular events, fatal and nonfatal, was recorded during the follow-up. During a median follow-up of 4.7 years (17 028 patients-year), 294 fatal and first nonfatal cardiovascular events were recorded (1.73 CVD per 100 patients/year). Independently of blood pressure, estimated glomerular filtration rate, level of cardiovascular risk, and antihypertensive treatment, microalbuminuria at baseline and at any time during the follow-up resulted in higher risk for events, hazard ratio (HR) 1.35 (95% confidence interval [CI], 1.08-1.79) and HR 1.49 (95% CI, 1.14-1.94), respectively. Likewise, development of microalbuminuria (HR 1.60; 95% CI, 1.04-2.46) or persistence from the beginning (1.53; 95% CI, 1.13-2.06) had a significantly higher rate of events than if remained normoalbuminuric (HR 1) or regress to normoalbuminuria (HR 1.37; 95% CI, 0.92-2.06) with an 18%, 18%, 8%, and 11% events, respectively, P<0.001. The study supports the value of urinary albumin excretion assessment as a prognostic factor for cardiovascular risk, but also opens the way to consider it as an intermediate objective in hypertension. © 2014 American Heart Association, Inc.

    New drug and medical device introduction in Japan usually lags behind that in the West. Many reports indicate that in Japan, the associated risks are considered greater than the benefits recognized in other countries. This study aimed to compare the relationship between risk-benefit perception and acceptance of medical technologies in 3 leading markets. A tripartite cross-sectional survey of the general public was used. In total, 3345 adults in the United Kingdom, the United States, and Japan participated, and sexes and age groups were equally represented. Questions about the perception of risk, benefit, and acceptance of medical and other scientific technologies, and trust of medical product providers or regulatory authorities were included. Five-step Likert coding for risk/benefit/acceptance of 4 medical items (x-rays, antibiotics, vaccines, and cardiac pacemakers) and 6 general items (such as automobiles and airplanes) were collected. Relationships between benefit perception and acceptance were linear for 4 medical technologies. The relationship had a similar slope but was shifted downward in Japan compared with the UK and US ( P medical technologies, benefits of medical technologies, trust in doctors, and trust in the Department of Health. The UK and US attributes were clustered with positive responses such as "useful," "acceptable," and "trustworthy," whereas Japan was clustered with intermediate to negative responses such as "neither" and "untrustworthy." Acceptance of medical technologies was low in Japan because of significant differences in trust for doctors and authorities compared with that in the UK and US. This is a possible basis for delays of 24 to 60 months for medical product approval in Japan.

    OBJECTIVES: to evaluate specialist geriatric input and medication review in patients in high-dependency continuing care. DESIGN: prospective, randomised, controlled trial. SETTING: two residential continuing care hospitals. PARTICIPANTS: two hundred and twenty-five permanent patients. INTERVENTION: patients were randomised to either specialist geriatric input or regular input. The specialist group had a medical assessment by a geriatrician and medication review by a multidisciplinary expert panel. Regular input consisted of review as required by a medical officer attached to each ward. Reassessment occurred after 6 months. RESULTS: one hundred and ten patients were randomised to specialist input and 115 to regular input. These were comparable for age, gender, dependency levels and cognition. After 6 months, the total number of medications per patient per day fell from 11.64 to 11.09 in the specialist group (P = 0.0364) and increased from 11.07 to 11.5 in the regular group (P = 0.094). There was no significant difference in mortality or frequency of acute hospital transfers (11 versus 6 in the specialist versus regular group, P = 0.213). CONCLUSION: specialist geriatric assessment and medication review in hospital continuing care resulted in a reduction in medication use, but at a significant cost. No benefits in hard clinical outcomes were demonstrated. However, qualitative benefits and lower costs may become evident over longer periods.

    To characterise a Taiwanese population and to examine the prevalence of antihypertensive medication non-adherence and how the cultural/clinical factors were associated with non-adherence in Taiwan. Antihypertensive medication non-adherence is a significant clinical issue in the United States. However, little is known about hypertension (HTN) control and cultural/clinical factors related to non-adherence in Taiwan. A convenience sample survey design was used. Data were gathered from a convenience sample of 200 subjects recruited from a large teaching hospital. Medication non-adherence and cultural/clinical factors were recorded using various self-administered questionnaires, and blood pressure was taken twice for each participant. The mean age of the participants was 60.4 (SD 11.5 years) including 62% men. Two-thirds had less than a high school education (64.5%), and the majority of them were married (86·0%) and lived with family or close friends (93.5%). The average length of HTN diagnosis was 8.6 years (SD 9.0 years). Medication non-adherence rate was 47·5%, and uncontrolled HTN rate was 49.0%. Some participants (17.0%) used Chinese herbs for treating their disease (e.g. cough) and promoting health in addition to their regular antihypertensive medications. Two factors were found to be statistically significant for predicting medication non-adherence: Lower Perceived Susceptibility to Specific Diseases [OR = 1.15 (95%CI, 1.01-1.31)] and Longer Length of HTN Diagnosis [OR = 1.06 (95%CI, 1.01-1.12)]. Taiwanese at risk of non-adherence included those who perceived lower susceptibility to specific diseases and had been diagnosed with HTN for a longer time. Those using herbs need to be studied for an impact of herbs on their adherence behaviour. These findings can help guide the development of culturally sensitive and clinically appropriate nursing interventions for HTN management in Taiwan. © 2012 Blackwell Publishing Ltd.

    Hypertension is one of the most important cardiovascular risk factor but its control is still a challenge for physicians all around the world. Control of blood pressure can reduce cardiovascular morbidity and mortality, so the compliance to antihypertensive drugs and life style modification play an important role for the control of hypertension. This analytical (cross-sectional) study was conducted to assess prevalence of control of hypertension among hypertensive patients and to assess the relationship of control of hypertension with factors like compliance to antihypertensive drugs, salt restriction and exercise among the hypertensive patients. This study was conducted at outpatient clinic of medicine at Shahina Jamil Hospital Abbottabad from April 2007 to September 2007. Eighty-nine patients seen in the outpatient clinic of medicine were enrolled in the study. All the patients with age 15 years or above, diagnosed as a case of systemic hypertension were included. Among eighty nine patients, 67 were female and 22 were male with mean age of 55.8+-13.4 years, mean systolic and diastolic blood pressure of 160+-28.6 and 97.8+-14.1 mm Hg respectively, and pulse rate of 85.9+-11.4 per minutes. Out of 89 patients, 25.8% were having controlled hypertension, 48.3% were compliant and 51.7% were not compliant to antihypertensive drugs, 55.1% were having salt restriction and 44.9% were having no salt restriction and 23.6% were used to do physical activity while 76.4% were not used to do physical activity. In group A consisted of patients with controlled hypertension, 95.7% patients were compliant to antihypertensive patients, 95.7% were having salt restriction and 43.5% were used to do physical activity. In group B consisted of patients with uncontrolled hypertension, only 31.8% were compliant to antihypertensive drugs, 40.9% were having salt restriction, 16.7% were used to do physical activity. Hypertension can be controlled if the hypertensive patients have good compliance

    Smart infusion pumps have been introduced to prevent medication errors and have been widely adopted nationally in the USA, though they are not always used in Europe or other regions. Despite widespread usage of smart pumps, intravenous medication errors have not been fully eliminated. Through a systematic review of recent studies and reports regarding smart pump implementation and use, we aimed to identify the impact of smart pumps on error reduction and on the complex process of medication administration, and strategies to maximize the benefits of smart pumps. The medical literature related to the effects of smart pumps for improving patient safety was searched in PUBMED, EMBASE, and the Cochrane Central Register of Controlled Trials (CENTRAL) (2000-2014) and relevant papers were selected by two researchers. After the literature search, 231 papers were identified and the full texts of 138 articles were assessed for eligibility. Of these, 22 were included after removal of papers that did not meet the inclusion criteria. We assessed both the benefits and negative effects of smart pumps from these studies. One of the benefits of using smart pumps was intercepting errors such as the wrong rate, wrong dose, and pump setting errors. Other benefits include reduction of adverse drug event rates, practice improvements, and cost effectiveness. Meanwhile, the current issues or negative effects related to using smart pumps were lower compliance rates of using smart pumps, the overriding of soft alerts, non-intercepted errors, or the possibility of using the wrong drug library. The literature suggests that smart pumps reduce but do not eliminate programming errors. Although the hard limits of a drug library play a main role in intercepting medication errors, soft limits were still not as effective as hard limits because of high override rates. Compliance in using smart pumps is key towards effectively preventing errors. Opportunities for improvement include upgrading drug

    Background Medication non-adherence is common and results in preventable disease complications. This study assesses the effectiveness of a multifactorial intervention to improve both medication adherence and blood pressure control and to reduce cardiovascular events. Methods and Results In this multi-center, cluster-randomized trial, physicians from hospital-based hypertension clinics and primary care centers across Spain were randomized to receive and provide the intervention to their high-risk patients. Eligible patients were ≥50 years of age, had uncontrolled hypertension, and had an estimated 10-year cardiovascular risk greater than 30%. Physicians randomized to the intervention group counted patients’ pills, designated a family member to support adherence behavior, and provided educational information to patients. The primary outcome was blood pressure control at 6 months. Secondary outcomes included both medication adherence and a composite end-point of all cause mortality and cardiovascular-related hospitalizations. Seventy-nine physicians and 877 patients participated in the trial. The mean duration of follow-up was 39 months. Intervention patients were less likely to have an uncontrolled systolic blood pressure (odds ratio 0.62; 95% confidence interval [CI] 0.50–0.78) and were more likely to be adherent (OR 1.91; 95% CI 1.19–3.05) when compared with control group patients at 6 months. After five years 16% of the patients in the intervention group and 19% in the control group met the composite end-point (hazard ratio 0.97; 95% CI 0.67–1.39). Conclusions A multifactorial intervention to improve adherence to antihypertensive medication was effective in improving both adherence and blood pressure control, but it did not appear to improve long-term cardiovascular events.

    Hypertension could cause significant worldwide health problems that affect 15-20% of all adults; according to National Health and Nutrition Examination Survey, about 29% of the adult population in the United States are hypertensive. Recent research has shown that peptides derived from the hydrolysis of food proteins can decrease blood pressure. This study was carried out to evaluate the hypotensive and antihypertensive potential of Mucuna pruriens protein hydrolysates in in vitro and in vivo models. M. pruriens protein concentrate was prepared by wet fractionation and enzymatically hydrolyzed using Alcalase ® , Flavourzyme ® , and the sequential system Alcalase-Flavourzyme at different times (5-120 min). The biological potential was measured in vitro based on the IC 50 value as well as in vivo effect, measuring the systolic (SBP) and diastolic (DBP) blood pressure in normotensive and antihypertensive Wistar-Kyoto rats by the tail-cuff method. Hydrolysis of M. pruriens protein concentrates with commercial enzymes generated extensive hydrolysates with angiotensin-converting enzyme (ACE-I) inhibitory activity (IC 50 : 0.589-0.993 mg/mL) and hypotensive (SBP: 0.6-47.43%, DBP: 1.94-43.47%) and antihypertensive (SBP: 8.84-27.29% DBP: 16.1-29.37%) effect. These results indicate that Mucuna pruriens protein hydrolysate (MPPH) could be used as a functional ingredient to prevent blood pressure increase.

    The present investigation was carried out to evaluate the effect of aerial parts of Sonchus asper L. in normotensive, glucose and egg feed diet induced hypertensive rats. Aqueous-methanolic extract of Sonchus asper in 250, 500 and 1000 mg/kg doses was studied in normotensive and glucose induced hypertensive rats using the non-invasive technique. The results obtained showed that the extract has significantly (p < 0.5 - p < 0.001) decreased the blood pressure and heart rate in dose dependent manner. The dose 1000 mg/kg of the extract produced the maximum antihypertensive effect and was selected for further experiments. The extract was found to prevent the rise in blood pressure of egg and glucose fed rats as compared to control group in 21 days study. The LD50 of the plant extract was 3500 mg/kg b.w. in mice and sub-chronic toxicity study showed that there was no significant alteration in the blood chemistry of the extract treated rats. It is conceivable, therefore, that the aqueous-methanolic extract of Sonchus asper has exerted considerable antihypertensive activity in rats and has duly supported traditional medicinal use of plant in hypertension.

    Full Text Available There is growing interest in using functional foods or nutraceuticals for the prevention and treatment of hypertension or high blood pressure. Although numerous preventive and therapeutic pharmacological interventions are available on the market, unfortunately, many patients still suffer from poorly controlled hypertension. Furthermore, most pharmacological drugs, such as inhibitors of angiotensin-I converting enzyme (ACE, are often associated with significant adverse effects. Many bioactive food compounds have been characterized over the past decades that may contribute to the management of hypertension; for example, bioactive peptides derived from various food proteins with antihypertensive properties have gained a great deal of attention. Some of these peptides have exhibited potent in vivo antihypertensive activity in both animal models and human clinical trials. This review provides an overview about the complex pathophysiology of hypertension and demonstrates the potential roles of food derived bioactive peptides as viable interventions targeting specific pathways involved in this disease process. This review offers a comprehensive guide for understanding and utilizing the molecular mechanisms of antihypertensive actions of food protein derived peptides.

    Medical exposure represents the main source of artificial irradiation of the population and it is determined by the use of diagnostic and therapeutic purposes of X-ray generators and sealed and unsealed sources in diagnostic radiology, nuclear medicine and radiotherapy. Benefits of use of ionizing radiation in medicine are very well recognized and they can be expressed in obtaining morphologic and functional information on lesions determined by a pathologic situation, undetected by other diagnostic methods and/or the destroy of neo-formative tissues, particularly malign, resisting to other medical treatments. Finally, the result is the reduction of lethality of those diseases which benefited from an early diagnostic and the extension of life expectancy, following radiotherapy. The potential risks of medical exposure are accepted as a fact. Epidemiological studies are known on increased incidences of leucoses in patients after irradiation of the spine for spondyl-arthritis and in children irradiated in-utero, high frequency of thyroid cancer in children irradiated for thymus persistence, diseases and hereditary malformations in children from irradiated parents. A special situation is the radiation protection of the unborn child. Do to the increased number of radiological medical procedures, there is a clear need for correct information of the public regarding the benefits (i.e. to not avoid any necessary procedure) and the risks (to reduce non-useful irradiation) of the medical exposure

    Although pharmacological treatment of hypertension has important health benefits, it does not capture the benefit of maintenance of ideal health through the prevention or delay of hypertension. A total of 26 875 black and white participants aged 45+ years were assessed and followed for incident stroke events. The association was assessed between incident stroke and: (1) systolic blood pressure (SBP)categorized as normal (pressure strata, the risk of stroke increased with each additional class of required antihypertensive medication, with hazard ratio [HR], 1.33; 95% confidence interval, 1.16 to 1.52 for normotensive, HR, 1.15; 95% confidence interval, 1.05 to 1.26 for prehypertension, and HR, 1.22; 95% confidence interval, 1.06 to 1.39 for stage 1 hypertension. A successfully treated (SBP<120 mm Hg) hypertensive person on 3+ antihypertensive medication classes was at marginally higher stroke risk than a person with untreated stage 1 hypertension (HR, 2.48 versus HR=2.19; relative to those with SBP <120 on no antihypertensive medications). Maintaining the normotensive status solely through pharmacological treatment has a profound impact, as nearly half of this general population cohort were treated to guideline (SBP<140 mm Hg) but failed to return to risk levels similar to normotensive individuals. Even with successful treatment, there is a substantial potential gain by prevention or delay of hypertension. © 2015 American Heart Association, Inc.

    Many patients with hypertension have legitimate reasons to forego standard blood pressure targets yet are nonetheless included in performance measurement systems. An approach to performance measurement incorporating clinical reasoning was developed to determine which patients to include in a performance measure. A 10-member multispecialty advisory panel refined a taxonomy of situations in which the balance of benefits and harms of anti-hypertensive treatment does not clearly favor tight blood pressure control (measurement for blood pressure control. These included (1) patients who have suffered adverse effects from multiple classes of antihypertensive medications; (2) patients already taking four or more antihypertensive medications; (3) patients with terminal disease, moderate to severe dementia, or other conditions that overwhelmingly dominate the patient's clinical status; and (4) other patient factors, including comfort care orientation and poor medication adherence despite attempts to remedy adherence difficulties. Several general principles also emerged. Performance measurement should focus on patients for whom the benefits of treatment clearly outweigh the harms and should incorporate a longitudinal approach. In addition, the criteria for exempting a patient from performance measurement should be more strict in patients at higher risk of adverse health outcomes from hypertension and more lenient for patients at lower risk. Incorporating "real world" clinical principles and judgment into performance measurement systems may improve targeting of care and, by accounting for patient case mix, allow for better comparison of performance between institutions.

    Full Text Available Abstract Background Self-care practices for patients with hypertension include adherence to medication, use of blood pressure self-monitoring and use of complementary and alternative therapies (CAM The prevalence of CAM use and blood pressure self-monitoring have not been described in a UK secondary care population of patients with hypertension and their impact on adherence to medication has not been described. Adherence to medication is important for blood pressure control, but poor adherence is common. The study aimed to determine the prevalence of self-care behaviours in patients attending a secondary care hypertension clinic. Methods Cross-sectional questionnaire survey. 196 patients attending a secondary care hypertension clinic in a teaching hospital serving a multiethnic population, Birmingham, UK. Main outcome measures: Prevalence of use of CAM, home monitors, adherence to anti-hypertensive medication. Results CAM use in previous 12 months was reported by 66 (43.1% respondents. CAM users did not differ statistically from non-CAM users by age, gender, marital status or education. Vitamins, prayer a dietary supplements were the most commonly used CAM. Nine (12.7% women reported using herbal CAM compared to one man (1.2%, (p = 0.006. Ten (6.7% respondents reported ever being asked by a doctor about CAM use. Perfect adherence to anti-hypertensive medication was reported by 26 (44.8% CAM-users and 46 (60.5% non-CAM users (p = 0.07. Being female and a CAM user was significantly associated with imperfect adherence to anti-hypertensive medication. Older and white British respondents were significantly more likely to report perfect adherence. Blood pressure monitors were used by 67 (43.8% respondents, which was not associated with gender, CAM use or adherence to medication. Conclusion Hypertensive patients use a variety of self-care methods, including CAM, home blood pressure monitors, and adherence to prescribed medication. This study found the

    Very soon after the discoveries of radiation and radioactivity, x rays were used in medical diagnosis. The benefits from this use were immediate and obvious, whereas the potential for harm was only discovered later. This paper reviews the historical trends and current situation in doses to patients from diagnostic radiology, to investigate whether the optimization requirement of radiological protection is being fully implemented. The use of constraints as a quantitative indicator is thought likely to help. Computed tomography is studied as an example of the introduction of a new technique with substantial diagnostic benefits but involving substantial doses. Doses to patients from nuclear medicine and radiotherapy are also reviewed. Doses to staff show trends that seem to indicate considerable attention to dose reduction. The overall conclusion is that the control of patient doses from diagnostic radiology is reasonable - but it could be better. (author). 54 refs

    Objectives: Assessing the clinical effectiveness of a topical sialogogue on spray (malic acid, 1%) in the treatment of xerostomia induced by antihypertensive drugs. Study Design: This research has been carried out through a randomized double-blind clinical trial. 45 patients suffering from hypertensive drugs-induced xerostomia were divided into 2 groups: the first group (25 patients) received a topical sialogogue on spray (malic acid, 1%) whereas the second group (20 patients) received a placebo. Both of them were administered on demand for 2 weeks. Dry Mouth Questionnaire (DMQ) was used in order to evaluate xerostomia levels before and after product/placebo application. Unstimulated and stimulated salivary flows rates, before and after application, were measured. All the statistical analyses were performed by using SPSS software v17.0. Different DMQ scores at the earliest and final stage of the trial were analysed by using Mann-Whitney U test, whereas Student’s T-test was used to analyse salivary flows. Critical p-value was established at p0.05) after placebo application. After two weeks of treatment with malic acid, unstimulated salivary flow increased from 0.17 to 0.242 mL/min whereas the stimulated one increased from 0.66 to 0.92 mL/min (p0.05). Conclusions: Malic acid 1% spray improved antihypertensive-induced xerostomia and stimulated the production of saliva. Key words:Xerostomia, hyposialia, malic acid, antihypertensive drugs.

    Full Text Available Background. Hypertension management is of a paramount importance in diabetic patients for cardiovascular risk reduction. Aim. To evaluate prescribing pattern of antihypertensive in T2DM (type 2 diabetes patients and compare with existing recent guidelines. Methods. A cross-sectional study involving evaluation of all T2DM patients referred to endocrinology unit at tertiary care centre for hypertension, comorbid complications, and recording prescription. Utilization of 5 different antihypertensive drug classes was compared for all patients receiving 1, 2, 3, 4, or more drugs. Logistical regression was used to assess likelihood of prescription of drugs and/or therapy for specific conditions mentioned in the guidelines. Results. Out of 1358, T2DM enrolled patients 1186 (87% had hypertension (males 52%, females 48%. The median duration (IQ of hypertension diabetics was 4 (1–10 years. A total of 25% patients had controlled BP and 75% with uncontrolled blood pressure (13% isolated systolic hypertension, 6% isolated diastolic hypertension, and 55% both elevated. Overall, ACE inhibitors (ACEIs were prescribed the highest (59% followed by angiotensin receptor blockers (ARBs (52%, calcium channel blockers (CCBs (29%, diuretics (27%, and beta-blockers (14%. Overall, 55% of T2DM patients were on polytherapy, 41% on monotherapy, and 4% had no antihypertensive treatment. Polytherapy was more predominant with age, duration of diabetes, duration of hypertension, and comorbid complications. Conclusion. Although prescribing pattern of antihypertensive showed adherence to existing evidence-based guidelines, higher proportion of uncontrolled hypertensive patients was found.

In the academic model, role congruency emerged as a benefit, and barriers were role strain and work-life conflict. Subscales of role strain included role conflict and role ambiguity for new employees. Role conflict stemmed from intersender conflict with coaches and athletics administrative personnel and interrole conflict with fulfilling multiple overlapping roles (academic, clinical, administrative).  The infrastructure in which ATs provide medical care needs to be evaluated. We found that the medical model can support better alignment for both patient care and the wellbeing of ATs. Whereas the academic model has perceived benefits, role incongruence exists, mostly because of the role complexity associated with balancing teaching, patient-care, and administrative duties.

    Poor anti-hypertension medication (AHT) adherence can increase disease costs and adverse outcomes. Hypertensive individuals who have a better nutrition knowledge may lead a healthier lifestyle, have a better health-related quality of life (HRQoL) and greater confidence to change behaviour. On this basis, they may have better treatment adherence. To explore the association between the above-mentioned variables and AHT adherence in a group of Australian adults with high blood pressure (BP) in a cross-sectional clinical and community-based study. Adults with high BP (n = 270) completed a questionnaire including: food frequency questionnaire (FFQ), nutrition knowledge, HRQoL, self-efficacy of diet and exercise, lifestyle and AHT adherence sections. Bivariate analysis and hierarchical logistic regression were used to explore the data. Three dietary patterns were identified from the FFQ, using factor and cluster analyses (Western, Snack and Alcohol, and Balanced). We observed that following a Western dietary pattern, having lower exercise self-efficacy and shorter sleep duration were more dominant in the poor AHT adherence individuals compared to their counterparts. A positive association was observed between self-efficacy and sleep duration with AHT adherence. A Western dietary pattern was prevalent in high BP participants which slightly reduced the likelihood of good adherence. A healthier dietary pattern, better exercise self-efficacy and adequate sleep (more than six hours a night) may increase the likelihood of AHT adherence in individuals with high BP. Interventions focusing on improving these variables are required to confirm the findings of this study.

    Previously we showed that feeding polyphenol-rich wild blueberries to hypertensive rats lowered systolic blood pressure. Since probiotic bacteria produce bioactive metabolites from berry polyphenols that enhance the health benefits of berry consumption, we hypothesized that adding probiotics to a blueberry-enriched diet would augment the anti-hypertensive effects of blueberry consumption. Groups (n = 8) of male spontaneously hypertensive rats were fed one of four AIN '93G-based diets for 8 weeks: Control (CON); 3% freeze-dried wild blueberry (BB); 1% probiotic bacteria (PRO); or 3% BB + 1% PRO (BB+PRO). Blood pressure was measured at weeks 0, 2, 4, 6, and 8 by the tail-cuff method, and urine was collected at weeks 4 and 8 to determine markers of oxidative stress (F2-isoprostanes), nitric oxide synthesis (nitrites), and polyphenol metabolism (hippuric acid). Data were analyzed using mixed models ANOVA with repeated measures. Diet had a significant main effect on diastolic blood pressure (p = 0.046), with significantly lower measurements in the BB- vs. CON-fed rats (p = 0.035). Systolic blood pressure showed a similar but less pronounced response to diet (p = 0.220), again with the largest difference between the BB and CON groups. Absolute increase in blood pressure between weeks 0 and 8 tended to be smaller in the BB and PRO vs. CON and BB+PRO groups (systolic increase, p = 0.074; diastolic increase, p = 0.185). Diet had a significant main effect on hippuric acid excretion (pblueberry-enriched diet does not enhance and actually may impair the anti-hypertensive effect of blueberry consumption. However, probiotic bacteria are not interfering with blueberry polyphenol metabolism into hippuric acid.

    Full Text Available Background: Black women have the highest prevalence of hypertension in the world. Reasons for this disparity are poorly understood. The historical legacy of medical maltreatment of Blacks in the U.S. provides some insight into distrust in the medical profession, refusal of treatment, and poor adherence to treatment regimens.Methods: Black women (N=80 who were prescribed antihypertensive medications were recruited from urban communities in North Carolina. Study participants completed the Trust in Physician and Hill-Bone Compliance to High Blood Pressure Therapy questionnaires. An exact discrete-event model was used to examine the relationship between trust and medication adherence.Results: Mean age of study participants was 48 ± 9.2 years. The majority of participants (67% were actively employed and 30% had incomes at or below the federal poverty level. Increasing levels of trust in the health care provider was independently associated with greater medication adherence (PTrend=0.015.Conclusions: Black women with hypertension who trusted their health care providers were more likely to be adherent with their prescribed antihypertensive medications than those who did not trust their health care providers. Findings suggest that trusting relationships between Black women and health care providers are important to decreasing disparate rates of hypertension.

    Through reduced out-of-pocket costs and wellness offerings, value-based benefit design (VBBD) is a promising strategy to improve medication adherence and other health-related outcomes across populations. There is limited evidence, however, of the effectiveness of these policy-level changes among individuals with anxiety or depression. To assess the impact of a multifaceted VBBD policy that incorporates waived copayments, wellness offerings, and on-site services on medication adherence among plan members with anxiety or depression, and to explore how this intervention and its resulting improved adherence affects other health-related outcomes. A retrospective longitudinal pre/post design was utilized to measure outcomes before and after the VBBD policy change. Repeated measures statistical regression models with correlated error terms were utilized to evaluate outcomes among employees of a self-insured global health company and their spouses (N = 529) who had anxiety or depression after the VBBD policy change. A multivariable linear regression model was chosen as the best fit to evaluate a change in medication possession ratio (MPR) after comparing parameters for several distributions. The repeated measures multivariable regression models were adjusted for baseline MPR and potential confounders, including continuous age, sex, continuous modified Charlson Comorbidity Index, and the continuous number of prescriptions filled that year. The outcomes were assessed for the 1 year before the policy change (January 1, 2011, through December 31, 2011) and for 2 years after the change (January 1, 2012, through December 31, 2013). The primary outcome was a change in MPR. The secondary outcomes included healthcare utilization, medical or pharmacy costs, the initiation of medication, generic medication use, and employee absenteeism (the total number of sick days). The implementation of the VBBD strategy was associated with a significant increase in average MPR (0.65 vs 0.61 in

    2010-12-01

    Benazepril is a nonsulfhydryl ACE inhibitor with favorable pharmacodynamic and pharmacokinetic properties, well-established antihypertensive effects and a good tolerability profile. Recent clinical studies have demonstrated that patients treated with benazepril alone or in combination with hydrochlorothiazide or amlodipine may achieve beneficial renal outcomes that extend beyond blood pressure control. Furthermore, the recent Avoiding Cardiovascular Events Through Combination Therapy in Patients Living with Systolic Hypertension (ACCOMPLISH) trial showed decreased cardiovascular morbidity and mortality with benazepril when administered as a cotreatment. An additional novel therapeutic area for benazepril is atrial fibrillation. Differences between combination therapies have implications for which patients may be best suited to particular interventions, and further studies are required to fully ascertain this potential.

    To determine if pharmacist involvement within a senior dining program benefits diners by addressing their medication-related questions, using educational sessions, and providing individual consultations. Catholic Charities Senior Dining sites in central Minnesota. Pharmacists went to three senior dining sites, providing educational sessions and individual consultations to independently living senior diners. Pharmacists developed a program, in a nontraditional setting, that used educational sessions and individual consultations to assist seniors with their medication-related questions. The number of diner questions, significant issues raised, issues addressed, and level of diner satisfaction. Pharmacists made 36 visits from January to December 2009. During those visits they presented educational talks to 3,089 diners, and 12.4% of all diners spoke individually with pharmacists. Pharmacists addressed 581 questions or concerns from 384 diners. Significant issues were noted in 25.8% of individual consultations (144 questions). The most common significant issues included: adverse drug reactions (59), indications without treatment (27), and drug interactions (23). Nonopioid analgesics, antilipemics, and antihypertensive medications were most commonly involved in significant issues. Satisfaction surveys were strongly positive, with 97% indicating pharmacists had addressed their medication-related concern; only 3% did not reply. Almost half (42.7%) of satisfaction surveys indicated the diner would change something as a result of meeting with the pharmacist. Pharmacist availability in a nontraditional setting can assist seniors with addressing potentially significant medication-related issues. Independently living seniors will seek out information from a pharmacist in a convenient setting.

    Citrus medica (Citron) is an underutilized fruit plant having various bioactive components in all parts of the plant. The major bioactive compounds present are iso-limonene, citral, limonene, phenolics, flavonones, vitamin C, pectin, linalool, decanal, and nonanal, accounting for several health benefits. Pectin and heteropolysachharides also play a major role as dietary fibers. The potential impact of citron and its bioactive components to prevent or reverse destructive deregulated processes responsible for certain diseases has attracted different researchers' attention. The fruit has numerous nutraceutical benefits, proven by pharmacological studies; for example, anti-catarrhal, capillary protector, anti-hypertensive, diuretic, antibacterial, antifungal, anthelmintic, antimicrobial, analgesic, strong antioxidant, anticancerous, antidiabetic, estrogenic, antiulcer, cardioprotective, and antihyperglycemic. The present review explores new insights into the benefits of citron in various body parts. Throughout the world, citron has been used in making carbonated drinks, alcoholic beverages, syrup, candied peels, jams, marmalade, cordials, and many other value added products, which suggests it is an appropriate raw material to develop healthy processed food. In the present review, the fruit taxonomical classification, beneficial phytochemicals, antioxidant activities, and health benefits are discussed.

    Hispanic-style cheeses are one of the fastest growing varieties in the United States, making up approximately 2% of the total cheese production in this country. Queso Fresco is one of most popular Hispanic-style cheeses. Protein extracts from several varieties of Mexican Queso Fresco and model Queso Fresco were analyzed for potential antihypertensive activity. Many Quesos Frescos obtained from Mexico are made from raw milk and therefore the native microflora is included in the cheese-making process. Model Queso Fresco samples were made from pasteurized milk and did not utilize starter cultures. Water-soluble protein extracts from 6 Mexican Quesos Frescos and 12 model cheeses were obtained and assayed for their ability to inhibit angiotensin-converting enzyme, implying potential as foods that can help to lower blood pressure. All model cheeses displayed antihypertensive activity, but mainly after 8 wk of aging when they were no longer consumable, whereas the Mexican samples did display some angiotensin-converting enzyme inhibitory action after minimal aging.

    The meat of Kacang goat has potential for production of a protein hydrolysate. Functional ingredients from protein hydrolysate of Kacang goat meat were determined by the consistency of angiotensin-converting enzyme (ACE) inhibitory activity and antihypertensive effect. This study examined the potency of Kacang goat protein hydrolysate in ACE inhibition and antihypertensive activity. Protein hydrolysates of Kacang goat meat were prepared using sequential digestion of endo-proteinase and protease complex at several concentrations and hydrolysis times. The highest ACE inhibitory activity resulted from a hydrolysate that was digested for 4 h with 5 g kg(-1) of both enzymes. An ACE inhibitory peptide was purified and a novel peptide found with a sequence of Phe-Gln-Pro-Ser (IC50 value of 27.0 µmol L(-1) ). Both protein hydrolysates and a synthesised peptide (Phe-Gln-Pro-Ser) demonstrated potent antihypertensive activities in spontaneously hypertensive rats. Protein hydrolysate of Kacang goat meat produced by sequential digestion with endo-proteinase and protease complex has great potential as a functional ingredient, particularly as an antihypertensive agent. © 2015 Society of Chemical Industry. © 2015 Society of Chemical Industry.

    Full Text Available Prospective postmarketing surveillance of Selara (eplerenone, a selective mineralocorticoid receptor antagonist, was performed to confirm its safety and efficacy for hypertension treatment in Japan. The change in blood pressure after initiation of eplerenone treatment was also examined. Patients with essential hypertension who were eplerenone-naïve were recruited regardless of the use of other antihypertensive drugs. For examination of changes in blood pressure, patients were excluded if eplerenone was contraindicated or used off-label. Patients received 50–100 mg of eplerenone once daily and were observed for 12 weeks. No treatments including antihypertensive drugs were restricted during the surveillance period. Across Japan, 3,166 patients were included for safety analysis. The incidence of adverse drug reactions was 2.4%. The major adverse drug reactions observed were hyperkalemia (0.6%, dizziness, renal impairment, and increased serum potassium (0.2% each. The mean systolic blood pressure decreased from 152.1±19.0 mmHg to 134.8±15.2 mmHg at week 12, and the mean diastolic blood pressure decreased from 85.8±13.7 mmHg to 77.7±11.4 mmHg. There were no significant new findings regarding the type or incidence of adverse reactions, and eplerenone had a clinically significant antihypertensive effect, leading to favorable blood pressure control.

    Renin-angiotensin aldosterone system (RAAS) blockade only partly reduces blood pressure, proteinuria and renal and cardiovascular risk in chronic kidney disease (CKD) but often requires sodium targeting [i.e. low sodium diet (LS) and/or diuretics] for optimal efficacy. However, both under- and overtitration of sodium targeting can easily occur. We evaluated whether N-terminal pro-brain natriuretic peptide (NT-proBNP), a biomarker of volume expansion, predicts the benefits of sodium targeting in CKD patients. In a cross-over randomized controlled trial, 33 non-diabetic CKD patients (proteinuria 3.8 ± 0.4 g/24 h, blood pressure 143/86 ± 3/2 mmHg, creatinine clearance 89 ± 5 mL/min) were treated during 6-week periods with placebo, angiotensin receptor blockade (ARB; losartan 100 mg/day) and ARB plus diuretics (losartan 100 mg/day plus hydrochlorothiazide 25 mg/day), combined with LS (93 ± 52 mmol Na(+)/24 h) and regular sodium diet (RS; 193 ± 62 mmol Na(+)/24 h, P diuretics and was normalized by ARB + diuretic + LS [39 (26-59) pg/mL, P = 0.65 versus controls]. NT-proBNP levels above the upper limit of normal (>125 pg/mL) predicted a larger reduction of blood pressure and proteinuria by LS and diuretics but not by ARB, during all steps of the titration regimen. Elevated NT-proBNP levels predict an enhanced anti-hypertensive and anti-proteinuric benefit of sodium targeting, but not RAAS blockade, in proteinuric CKD patients. Importantly, this applies to the untreated condition, as well as to the subsequent treatment steps, consisting of RAAS blockade and even RAAS blockade combined with diuretics. NT-proBNP can be a useful tool to identify CKD patients in whom sodium targeting can improve blood pressure and proteinuria.

    Zn/Al layered double hydroxides (LDHs) were intercalated with the anionic antihypertensive drugs Enalpril, Lisinopril, Captopril and Ramipril by using coprecipitation or ion-exchange technique. TG-MS analyses suggested that the thermal stability of Ena - , Lis - (arranged with monolayer, resulted from X-ray diffraction (XRD) and Fourier transform infrared spectra (FT-IR) analysis was enhanced much more than Cap - and Ram - (arranged with bilayer). The release studies show that the release rate of all samples markedly decreased in both pH 4.25 and 7.45. However, the release time of Ena - , Lis - were much longer compared with Cap - , Ram - in both pH 4.25 and 7.45, it is possible that the intercalated guests, arranged with monolayer in the interlayer, show lesser repulsive force and strong affinity with the LDH layers. And the release data followed both the Higuchi-square-root law and the first-order equation well. Based on the analysis of batch release, intercalated structural models as well as the TG-DTA results, we conclude that for drug-LDH, stronger the affinity between intercalated anions and the layers is, better the thermal property and the stability to the acid attack of drug-LDH, and the intercalated anions are easier apt to monolayer arrangement within the interlayer, were presented. - Graphical abstract: A series of antihypertensive drugs including Enalpril, Lisinopril, Captopril and Ramipril were intercalated into Zn/Al-NO 3 -LDHs successfully by coprecipitation or ion-exchange technique. We focus on the structure, thermal property and low/controlled release property of as-synthesized drug-LDH composite intended for the possibility of applying these LDH-antihypertensive nanohybrids in drug delivery and controlled release systems

    Equity is one of the essential objectives of the social health insurance. This article evaluates the benefit distribution of the China's Urban Residents' Basic Medical Insurance (URBMI), covering 300 million urban populations. Using the URBMI Household Survey data fielded between 2007 and 2011, we estimate the benefit distribution by the two-part model, and find that the URBMI beneficiaries from lower income groups benefited less than that of higher income groups. In other words, government subsidy that was supposed to promote the universal coverage of health care flew more to the rich. Our study provides new evidence on China's health insurance system reform, and it bears meaningful policy implication for other developing countries facing similar challenges on the way to universal coverage of health insurance. © The Author 2016.

    The research aimed at investigating sales trends of angiotensin-converting enzyme inhibitors antihypertensive medicines, both in terms of quantity and value, in ten community pharmacies, for a period of three years. The research on the antihypertensive medicines consumption is important for highlighting the ever increasing impact of hypertension among the population. The methods used in this research were the following: marketing research, method of sampling, descriptive methods, retrospective analysis, method of comparison. The results showed that the drugs containing the active substances of the angiotensin converting enzyme inhibitors class had had significant increases in quantitative and value sales, bringing substantial revenues to pharmacies. From the quantitative perspective, the best-selling products were those containing Enalaprilum, while in terms of value, the best-selling medicines were those containing Perindoprilum. We evidenced that spectacular sales were also achieved for products that have Lisinoprilum, respectively Captoprilum, as active substances. The largest quantities were marketed for the Captopril Terapia® product and the highest earnings were recorded for the Prestarium® medicine. This paper approaches an interesting and topical issue, which can be helpful to professionals (pharmacists, doctors) and other categories, such as economists, statisticians, representatives of companies manufacturing medicines, as well as to hypertensive patients, as it could be used to warn population regarding the incidence of cardiovascular diseases, and, at the same time, trace sales trends in order to accomplish profitable business plans.

    Risk attitudes and personality traits are known predictors of decision making among laypersons, but very little is known of their influence among experts participating in organizational decision making. Seventy-five European medical assessors were assessed in a field study using the Domain Specific Risk Taking scale and the Big Five Inventory scale. Assessors rated the risks and benefits for a mock "clinical dossier" specific to their area of expertise, and ordinal regression models were used to assess the odds of risk attitude or personality traits in predicting either the benefit or the risk ratings. An increase in the "conscientiousness" score predicted an increase in the perception of the drug's benefit, and male assessors gave higher scores for the drug's benefit ratings than did female assessors. Extraverted assessors saw fewer risks, and assessors with a perceived neutral-averse or averse risk profile saw greater risks. Medical assessors perceive the benefits and risks of medicines via a complex interplay of the medical situation, their personality traits and even their gender. Further research in this area is needed to determine how these potential biases are managed within the regulatory setting.

    To investigate the independent effects of antihypertensive treatment and blood pressure (BP) levels on physical and mental health status in patients with arterial disease. Cross-sectional analyses were conducted within the single-centre Secondary Manifestations of ARTerial disease (SMART) study, in a hospital care setting. A total of 5877 patients (mean age 57 years) with symptomatic and asymptomatic arterial disease underwent standardized vascular screening. The primary outcome was self-rated physical and mental health assessed using the 36-item short-form health survey. In the total population, antihypertensive drug use and increased intensity of antihypertensive treatment were associated with poorer health status independent of important confounders including BP levels; adjusted mean differences [95% confidence interval (CI)] in physical and mental health between n = 0 and n ≥ 3 antihypertensives were -1.2 (-2.1; -0.3) and -3.5 (-4.4; -2.6), respectively. Furthermore, both lower systolic and lower diastolic BP levels were related to poorer physical and mental health status independent of antihypertensive treatment. Mean differences (95% CI) in physical and mental health status per SD decrease in systolic BP were -0.56 (-0.84; -0.27) and -0.32 (-0.61; -0.03) and per SD decrease in diastolic BP were -0.50 (-0.78; -0.23) and -0.08 (-0.36; 0.20), respectively. The association between low BP and poor health status was particularly present in patients with coronary artery disease. In a population of patients with asymptomatic and symptomatic arterial disease, antihypertensive treatment and lower BP levels are independently associated with poorer self-rated physical and mental health. These findings suggest that different underlying mechanisms may explain these independent associations. © 2013 The Association for the Publication of the Journal of Internal Medicine.

    This study aimed to assess the prevalence, awareness, treatment, and control of hypertension and their associated factors among Bai ethnic population in the rural China. A population-based survey was conducted in 2010 with a randomly cluster sampling in rural communities in Dali, southwest China. A total of 2133 adults aged 50 or above were interviewed, and their blood pressure, height, weight and waist circumference were measured. Hypertension was defined as a mean SBP≥140 mmHg and/or DBP≥90 mmHg, and/or current use of antihypertensive medications. The prevalence of hypertension was 42.1% (899/2133), and the age- and gender-adjusted prevalence was 40.0%. Among the hypertensive participants, 28.4% (255/899)were aware of their condition, while 24.6% (221/899) took antihypertensive medications, with only 7.5% (67/899) of those achieving blood pressure control (population of Bai ethnic group in China, while the associated risk factors of hypertension include overweight/obesity, cigarette smoking, history of hypertension, and older age. The percentages of hypertensive participants aware of their hypertension and those taking antihypertensive medications were low with an incredibly low proportion of hypertensive patients who kept their hypertension under control. It is suggested that health education and hypertension screening programs be carried out in the area for the high blood pressure prevention and control.

    Understanding the molecular mode of action of natural product is a key step for developing drugs from them. In this regard, this study is aimed to understand the molecular-level interactions of chemical constituents of Clerodendrum colebrookianum Walp., with anti-hypertensive drug targets using computational approaches. The plant has ethno-medicinal importance for the treatment of hypertension and reported to show activity against anti-hypertensive drug targets-Rho-associated coiled-coil protein kinase (ROCK), angiotensin-converting enzyme, and phosphodiesterase 5 (PDE5). Docking studies showed that three chemical constituents (acteoside, martinoside, and osmanthuside β6) out of 21 reported from the plant to interact with the anti-hypertensive drug targets with good glide score. In addition, they formed H-bond interactions with the key residues Met156/Met157 of ROCK I/ROCK II and Gln817 of PDE5. Further, molecular dynamics (MD) simulation of protein-ligand complexes suggest that H-bond interactions between acteoside/osmanthuside β6 and Met156/Met157 (ROCK I/ROCK II), acteoside and Gln817 (PDE5) were stable. The present investigation suggests that the anti-hypertensive activity of the plant is due to the interaction of acteoside and osmanthuside β6 with ROCK and PDE5 drug targets. The identified molecular mode of binding of the plant constituents could help to design new drugs to treat hypertension.

    Nutritional fact study has prime importance to make the species edible and commercially viable to the food consumers. This is the first report that indicates the chemical characterization, functional, antioxidant and antihypertensive properties of Cymodocea nodosa to evaluate its nutritional status. Physico-chemical determination was determined by colorimetric and spectroscopic analysis. The functional and texture properties were evaluated since a desirable texture should be retained. Bioactive substances were determined by liquid chromatography-high resolution electrospray ionization mass spectrometry HPLC-DAD-ESI/MS2 analysis. Health benefit of this plant was highlighting by the antioxidant and antihypertensive potentials. Results showed that the seagrass powder was characterized by a high content of fibers (56.4%), the fatty acids profile was dominated by the oleic acid, which represents about 62.0% of the total fatty acids and the functional properties proved important values of swelling capacity (6.71 ± 0.2) and water holding capacity (12.26 ± 0.25), that were comparable to those of some foodstuffs. Finally, the physico-chemical analysis shows the wealth in phenolic compounds, that could be explained by the high antioxidant and antihypertensive ability which was concentration dependent. The results from this study suggested that this marine plant could be utilized as a healthy food item for human consumption.

    Adequate radiation shielding is vital to the safe operation of modern commercial medical cyclotrons producing large yields of short-lived radioisotopes. The radiological shielding constitutes a significant capital investment for any new cyclotron-based radioisotope production facility; hence, the shielding design requires an accurate cost-benefit analysis often based on a complex multi-variant optimization technique. This paper demonstrates the application of a Genetic Algorithm (GA) for the optimum design of the high yield target cave of a Medical Cyclotron radioisotope production facility based in Sydney, Australia. The GA is a novel optimization technique that mimics the Darwinian Evolution paradigm and is ideally suited to search for global optima in a large multi-dimensional solution space

The present work investigates the acute and chronic antihypertensive effects of the methanol extract of Cinnamomum zeylanicum stem bark (MECZ in L-NAME-induced hypertensive rats. Methods The acute antihypertensive effects of MECZ (5, 10 and 20 mg/kg administered intravenously were evaluated in rats in which acute arterial hypertension has been induced by intravenous administration of L-NAME (20 mg/kg. For chronic antihypertensive effects, animals were treated with L-NAME (40 mg/kg/day plus the vehicle or L-NAME (40 mg/kg/day in combination with captopril (20 mg/kg/day or MECZ (300 mg/kg/day and compared with control group receiving only distilled water. All drugs were administered per os and at the end of the experiment that lasted for four consecutive weeks, blood pressure was measured by invasive method and blood samples were collected for the determination of the lipid profile. The heart and aorta were collected, weighed and used for both histological analysis and determination of NO tissue content. Results Acute intravenous administration of C. zeylanicum extract (5, 10 and 20 mg/kg to L-NAME-induced hypertensive rats provoked a long-lasting decrease in blood pressure. Mean arterial blood pressure decreased by 12.5%, 26.6% and 30.6% at the doses of 5, 10 and 20 mg/kg, respectively. In chronic administration, MECZ and captopril significantly prevented the increase in blood pressure and organs’ weights, as well as tissue histological damages and were able to reverse the depletion in NO tissue’s concentration. The MECZ also significantly lower the plasma level of triglycerides (38.1%, total cholesterol (32.1% and LDL-cholesterol (75.3% while increasing that of HDL-cholesterol (58.4% with a significant low atherogenic index (1.4 versus 5.3 for L-NAME group.

    Diagnostic and therapeutic radiology is playing a major role in modern medicine. A preliminary survey was carried out during 1997 on 3 major Israeli hospitals in order to assess the extent of exposure of the population to medical x-rays (1). The survey has found that the annual collective dose of the Israeli population to x-ray medical imaging procedures (excluding radio-therapy) is about 7,500 Man-Sv. The results of the survey were analyzed in order to. 1. Carry out a cost-benefit optimization procedure related to the means that should be used to reduce the exposure of the Israeli patients under x-ray procedures. 2. Establish a set of practical recommendations to reduce the x-ray radiation exposure of patients and to increase the image quality. . Establish a number of basic rules to be utilized by health policy makers in Israel. Based on the ICRP-60 linear model risk assessments (2), the extent of the annual risk arising A.om the 7,500 Man-Sv medical x-ray collective dose in Israel has been found to be the potential addition of 567 cancer cases per year, 244 of which to be fatal, and a potential additional birth of 3-4 children with severe genetic damage per year. This assessment take into account the differential risk and the collective dose according to the age distribution in the Israeli exposed population, and excludes patients with chronic diseases

    Despite increased awareness, poor adherence to treatments for chronic diseases remains a global problem. Adherence issues are common in patients taking antihypertensive therapy and associated with increased risks of coronary and cerebrovascular events. Whilst there has been a gradual trend toward improved control of hypertension, the number of patients with blood pressure values above goal has remained constant. This has both personal and economic consequences. Medication adherence is a multifaceted issue and consists of three components: initiation, implementation, and persistence. A combination of methods is recommended to measure adherence, with electronic monitoring and drug measurement being the most accurate. Pill burden, resulting from free combinations of blood pressure lowering treatments, makes the daily routine of medication taking complex, which can be a barrier to optimal adherence. Single-pill fixed-dose combinations simplify the habit of medication taking and improve medication adherence. Re-packing of medication is also being utilized as a method of improving adherence. This paper presents the outcomes of discussions by a European group of experts on the current situation of medication adherence in hypertension.

    Employee wellness programs aim to assist in controlling employer costs by improving the health status and fitness of employees, potentially increasing productivity, decreasing absenteeism, and reducing medical claims. Most such programs offer no disincentive for nonparticipation. We evaluated an incentive/disincentive program initiated by a large teaching hospital in western Michigan. The HealthPlus Health Quotient program is an incentive/disincentive approach to health promotion. The employer's contribution to the cafeteria plan benefit package is adjusted based on results of an annual appraisal of serum cholesterol, blood pressure, tobacco use, body fat, physical fitness, motor vehicle safety, nutrition, and alcohol consumption. The adjustment (health quotient [HQ]) can range from -$25 to +$25 per pay period. We examined whether appraised health improved between 1993 and 1996 and whether the HQ predicted medical claims. Mean HQ increased slightly (+$0.47 per pay period in 1993 to +$0.89 per pay period in 1996). Individuals with HQs of less than -$10 per pay period incurred approximately twice the medical claims of the other groups (test for linear trend, p = .003). After adjustment, medical claims of employees in the worst category (HQ benefits. Most employees are impacted minimally, but savings are accruing to the employer from reductions in medical claims paid and in days lost to illness and disability.

    Methodological issues are pointed to as the main sources of inconsistencies in studies about the association between job strain and blood pressure (BP)/hypertension. Our aim was to analyze the relationship between job strain and the whole BP distribution, as well as potential differences by gender, age, and use of antihypertensives. Additionally, we addressed issues relating to the operationalization of the exposure and outcome variables that influence the study of their inter-relations. We evaluated the baseline date of 12,038 participants enrolled in the Brazilian Longitudinal Study of Adult Health (ELSA-Brasil) (2008–2010), a multicenter cohort study of 35–74-year-old civil servants. Job strain was assessed by the Demand-Control-Support Questionnaire. The distribution of casual BP by categories of job strain was compared by a combination of exploratory techniques. Participants were classified into three subgroups (normotensives, medicated hypertensives, and unmedicated hypertensives), and analyses were stratified by gender and age. The relationship between job strain and casual BP varied along the whole outcome distribution. Hypertensive participants had greater differences in casual BP by job strain category, especially medicated hypertensives. Differences in casual BP were also greater for systolic than for diastolic BP and for older participants. No differences were encountered by gender. The exclusion of participants susceptible to misclassification for the exposure and outcome variables increased the differences observed between the categories of low and high job strain. In conclusion, the relationship between job strain and casual BP varied along the whole outcome distribution and by use of antihypertensive drugs, age, and BP parameter evaluated. Misclassification for exposure and outcome variables should be considered in analyses of this topic. PMID:28441727

    The objective of the present study was to assess the regression of left ventricular hypertrophy (LVH) during antihypertensive treatment, and its relationship with the changes in microalbuminuria. One hundred and sixty-eight previously untreated patients with echocardiographic LVH, 46 (27%) with microalbuminuria, were followed during a median period of 13 months (range 6-23 months) and treated with lifestyle changes and antihypertensive drugs. Twenty-four-hour ambulatory blood pressure monitoring, echocardiography and urinary albumin excretion were assessed at the beginning and at the end of the study period. Left ventricular mass index (LVMI) was reduced from 137 [interquartile interval (IQI), 129-154] to 121 (IQI, 104-137) g/m (P 50%) had the same odds of achieving regression of LVH as patients with normoalbuminuria (ORm 1.1; 95% CI 0.38-3.25; P = 0.85). However, those with microalbuminuria at baseline, who did not regress, had less probability of achieving LVH regression than the normoalbuminuric patients (OR 0.26; 95% CI 0.07-0.90; P = 0.03) even when adjusted for age, sex, initial LVMI, GFR, blood pressure and angiotensin-converting enzyme inhibitor (ACE-I) or angiotensin receptor blocker (ARB) treatment during the follow-up. Patients who do not have a significant reduction in microalbuminuria have less chance of achieving LVH regression, independent of blood pressure reduction.

    Though pharmacy claims data are commonly used to study medication adherence, there remains no standard operational definition for adherence especially for patients on multiple medications. Even when studies use the same terminology, the actual methods of calculating adherence can differ drastically. It is unclear whether the use of different definitions results in different conclusions regarding adherence and associated outcomes. The objective of our study was to compare adherence rates and associations with mortality using different operational definitions of adherence, and using various methods of handling concurrent medication use. We conducted a cohort study of patients aged ≥65 years from Manitoba, Canada, with incident hypertension diagnosed in 2004 and followed to 2009. We calculated adherence rates to anti-hypertensive medications using different operational definitions of medication adherence (including interval and prescription based medication possession ratios [MPR] and proportion of days covered [PDC]). For those on concurrent medications, we calculated adherence rates using the different methods of handling concurrent medication use, for each definition. We used logistic regression to determine the association between adherence and mortality for each operational definition. Among 2199 patients, 24.1% to 90.5% and 71.2% to 92.7% were considered adherent when using fixed interval and prescription-based interval medication possession ratios [MPRi and MPRp] respectively, depending on how concurrent medications were handled. Adherence was inversely associated with death, with the strongest association for MPRp measures. This association was significant only when considering adherence to any anti-hypertensive [aOR 0.70, 95% CI 0.51, 0.97], or when the mean of the class-specific MPRp's [adjusted OR 0.71, 95% CI 0.53, 0.95] was used. No significant association existed when the highest or lowest class-specific MPRp was used as the adherence estimate. The

    Health care costs in the United States are increasing unsustainably, and further efforts to control costs are inevitable and essential. Efforts to control expenditures should focus on the value, in addition to the costs, of health care interventions. Whether an intervention provides high value depends on assessing whether its health benefits justify its costs. High-cost interventions may provide good value because they are highly beneficial; conversely, low-cost interventions may have little or no value if they provide little benefit. Thus, the challenge becomes determining how to slow the rate of increase in costs while preserving high-value, high-quality care. A first step is to decrease or eliminate care that provides no benefit and may even be harmful. A second step is to provide medical interventions that provide good value: medical benefits that are commensurate with their costs. This article discusses 3 key concepts for understanding how to assess the value of health care interventions. First, assessing the benefits, harms, and costs of an intervention is essential to understand whether it provides good value. Second, assessing the cost of an intervention should include not only the cost of the intervention itself but also any downstream costs that occur because the intervention was performed. Third, the incremental cost-effectiveness ratio estimates the additional cost required to obtain additional health benefits and provides a key measure of the value of a health care intervention.

    In the past years, an enormous increase in the number of available health-related applications (apps) has occurred, from approximately 5800 in 2011 to over 23,000 in 2013, in the iTunes store. However, little is still known regarding the use, possible effectiveness, and risks of these applications. In this study, we focused on apps and other e-tools related to medicine use. A large subset of the general population uses medicines and might benefit from tools that aid in the use of medicine. The aim of the present study was to gain more insight into the characteristics, possible risks, and possible benefits of health apps and e-tools related to medication use. We first made an inventory of apps and other e-tools for medication use (n=116). Tools were coded by two independent researchers, based on the information available in the app stores and websites. Subsequently, for one type of often downloaded apps (aimed at people with diabetes), we investigated users' experiences using an online questionnaire. Results of the inventory show that many apps for medication use are available and that they mainly offer simple functionalities. In line with this, the most experienced benefit by users of apps for regulating blood glucose levels in the online questionnaire was "information quick and conveniently available". Other often experienced benefits were improving health and self-reliance. Results of the inventory show that a minority of the apps for medication use has potentially high risks and for many of the apps it is unclear whether and how personal data are stored. In contrast, online questionnaire among users of apps for blood glucose regulation indicates that they hardly ever experience problems or doubts considering reliability and/or privacy. Although, respondents do mention to experience disadvantages of use due to incomplete apps and apps with poor ease of use. Respondents not using app(s) indicate that they might use them in the future if reliability of the apps and

    Contemporary medical therapy consists of identification and treatment of all patient-modifiable vascular risk factors. Specific atherosclerotic disease therapies are designed to reduce the risk of thrombosis, and the disease progression in order to reduce the risk of future cardiovascular events. Contemporary medical management emphasizes the need to support the patient in achieving lifestyle modifications and to adjust medication to achieve individualized target values for specific quantifiable risk factors. Antiplatelet therapy in the form of aspirin or clopidogrel is routinely used for the prevention of ischemic stroke in patients who have had a transient ischemic attack or stroke. There is evidence from a recent trial that the use of combination antiplatelet therapy with aspirin and clopidogrel started within 24 hours of minor stroke or transient ischemic attack reduces the risk of recurrent stroke compared to the use of aspirin alone, and therefore we use aspirin plus clopidogrel in recently symptomatic patients with carotid stenosis pending carotid revascularization. Anticoagulation with heparins or vitamin K antagonist is not recommended except in patients at risk for cardio-embolic events. Lowering blood pressure to target levels has been shown to slow down the progression of carotid artery stenosis and reduces the intima-media thickness of the carotid plaque, while lowering lipid levels with statins has become an essential element in the medical therapy of carotid artery stenosis. Diabetes management should be optimized. Lifestyle choices, including tobacco smoking, physical inactivity, unhealthy diet, obesity, and excessive alcohol intake, are all important modifiable vascular risk factors. The combination of dietary modification, physical exercise, and use of aspirin, a statin, and an antihypertensive agent can be expected to give a cumulative relative stroke risk reduction of 80%. The evidence suggests that intensive medical therapy is so effective that

    Once the decision has been made to adopt an integrated medical information system (IMIS), there are a number of tissues to overcome. Users need to be aware of the impact the change will make on end users and be prepared to address issues that arise before they become problems. The purpose of this study is to investigate the benefits and unexpected problems encountered in the implementation of IMIS and to determine a useful framework for IMIS. The Yonsei University Dental Hospital is steadily constructing an IMIS. The vendor's PACS software, Piview STAR, supports transactions between workstations that are approved to integrating the health care enterprise (IHE) with security function. It is necessary to develop an excellent framework that is good for the patient, health care provider and information system vendors, in an expert, efficient, and cost-effective manner. The problems encountered with IMIS implementation were high initial investments, delay of EMR enforcement, underdevelopment of digital radiographic appliances and software and insufficient educational training for users. The clinical environments of dental IMIS is some different from the medical situation. The best way to overcome these differences is to establish a gold standard of dental IMIS integration, which estimates the cost payback. The IHE and its technical framework are good for the patient, the health care provider and all information systems vendors.

    The purpose of the International Commission on Radiological Protection (ICRP) Committee 3 Working Party was to update the 2001 web-based module 'Radiation and your patient: a guide for medical practitioners' from ICRP. The key elements of this task were: to clearly identify the target audience (such as healthcare providers with an emphasis on primary care); to review other reputable sources of information; and to succinctly publish the contribution made by ICRP to the various topics. A 'question-and-answer' format addressing practical topics was adopted. These topics included benefits and risks of imaging using ionising radiation in common medical situations, as well as pertaining to specific populations such as pregnant, breast-feeding, and paediatric patients. In general, the benefits of medical imaging and related procedures far outweigh the potential risks associated with ionising radiation exposure. However, it is still important to ensure that the examinations are clinically justified, that the procedure is optimised to deliver the lowest dose commensurate with the medical purpose, and that consideration is given to diagnostic reference levels for particular classes of examinations. © The International Society for Prosthetics and Orthotics.

    Background--Patients with aortic stenosis (AS) often have concomitant hypertension. Antihypertensive treatment with a β-blocker (Bbl) is frequently avoided because of fear of depression of left ventricular function. However, it remains unclear whether antihypertensive treatment with a Bbl...... is associated with increased risk of cardiovascular events in patients with asymptomatic mild to moderate AS. Methods and Results--We did a post hoc analysis of 1873 asymptomatic patients with mild to moderate AS and preserved left ventricular ejection fraction in the SEAS (Simvastatin and Ezetimibe in Aortic......

    Canary seed (Phalaris canariensis) is used to feed birds but it has been recently considered a promising cereal with nutraceutical potential for humans. The aim of this work was to analyze the protein fractions from canary seed flour and from milk substitutes (prepared by soaking the seeds in water 12 and 24 h), and to evaluate antioxidant and antihypertensive capacity of peptides obtained after in vitro digestion. Prolamins were the major protein fraction, followed by glutelins. After digestion, albumins and prolamins fractions from milks presented higher levels of peptides than flour, globulins showed more peptides in flour and glutelins were found in similar concentrations in all samples; 24 h milk prolamins had the highest concentration of peptides. Purification by high performance liquid chromatography (HPLC), sequencing of peptides, in vitro antioxidant ABTS (2,2'-azino-bis, 3-ethylbenzothiazoline-6-sulphonic acid) and DPPH (2,2-diphenyl-1-picrylhydrazyl) assays, and antihypertensive capacity (angiotensin converting enzyme (ACE) assay), indicated that peptides from canary seed prolamins were the most efficient compounds with antioxidant and antihypertensive activity. Canary seeds may be considered an accessible and cheap source to prepare milk substitutes with high contents of bioactive peptides with remarkable functional properties to promote better human health and healthy ageing.

    Marine invertebrates are one of the major groups of organisms, which could be diversified under the major taxonomic groups of Porifera, Cnidaria, Mollusca, Arthropoda, Echinodermata, and many other minor phyla. To date, range of medicinal benefits and a significant number of marine natural products (MNPs) have been discovered from marine invertebrates. Seafood diet from edible marine invertebrates such as mollusks and crustaceans has been linked with various medicinal benefits to improve human health. Among marine invertebrates, spongers from phylum Porifera is the most dominant group responsible for discovering large number of MNPs, which have been used as template to develop therapeutic drugs. MNPs isolated from invertebrates have shown wide range of therapeutic properties including antimicrobial, antioxidant, antihypertensive, anticoagulant, anticancer, anti-inflammatory, wound healing and immune modulator, and other medicinal effects. Therefore, marine invertebrates are rich sources of chemical diversity and health benefits for developing drug candidates, cosmetics, nutritional supplements, and molecular probes that can be supported to increase the healthy life span of human.

  8. Probiotics Blunt the Anti-Hypertensive Effect of Blueberry Feeding in Hypertensive Rats without Altering Hippuric Acid Production.

    Directory of Open Access Journals (Sweden)

    Full Text Available Previously we showed that feeding polyphenol-rich wild blueberries to hypertensive rats lowered systolic blood pressure. Since probiotic bacteria produce bioactive metabolites from berry polyphenols that enhance the health benefits of berry consumption, we hypothesized that adding probiotics to a blueberry-enriched diet would augment the anti-hypertensive effects of blueberry consumption. Groups (n = 8 of male spontaneously hypertensive rats were fed one of four AIN '93G-based diets for 8 weeks: Control (CON; 3% freeze-dried wild blueberry (BB; 1% probiotic bacteria (PRO; or 3% BB + 1% PRO (BB+PRO. Blood pressure was measured at weeks 0, 2, 4, 6, and 8 by the tail-cuff method, and urine was collected at weeks 4 and 8 to determine markers of oxidative stress (F2-isoprostanes, nitric oxide synthesis (nitrites, and polyphenol metabolism (hippuric acid. Data were analyzed using mixed models ANOVA with repeated measures. Diet had a significant main effect on diastolic blood pressure (p = 0.046, with significantly lower measurements in the BB- vs. CON-fed rats (p = 0.035. Systolic blood pressure showed a similar but less pronounced response to diet (p = 0.220, again with the largest difference between the BB and CON groups. Absolute increase in blood pressure between weeks 0 and 8 tended to be smaller in the BB and PRO vs. CON and BB+PRO groups (systolic increase, p = 0.074; diastolic increase, p = 0.185. Diet had a significant main effect on hippuric acid excretion (p<0.0001, with 2- and ~1.5-fold higher levels at weeks 4 and 8, respectively, in the BB and BB+PRO vs. PRO and CON groups. Diet did not have a significant main effect on F2-isoprostane (p = 0.159 or nitrite excretion (p = 0.670. Our findings show that adding probiotics to a blueberry-enriched diet does not enhance and actually may impair the anti-hypertensive effect of blueberry consumption. However, probiotic bacteria are not interfering with blueberry polyphenol metabolism into hippuric

    To assess trends in prescriptions, determinants and timing of treatment discontinuation and/or changes in antihypertensive drug therapy in a cohort of hypertensive patients living in Pavia, a city in the north of Italy. The cohort included 61 493 patients aged ≥18 years who received their first antihypertensive drug prescription (monotherapy, fixed or extemporaneous combination) during the period 2003-6. Patients were classified as 'persistent' if 12 months after the beginning of treatment they were still taking a regular therapy (same drug = 'same therapy users', added one or more drugs = 'add-on therapy users', different drug = 'switchers'). Otherwise, they were classified as 'non-persistent' (stopping therapy after the first prescription = 'occasional users'; stopping treatment early = 'stoppers'; taking medicines in an erratic fashion = 'intermittent users'). ACE inhibitors were the most frequently prescribed drugs (22.8%), followed by β-adrenoceptor antagonists (β-blockers) [14.3%], diuretics (13.9%), Ca(2+) antagonists (11.4%) and angiotensin II type 1 receptor antagonists (angiotensin receptor blockers [ARBs]) [9.3%]. After 12 months, persistent patients were only 11.2% (same therapy users 6.7%, switchers 3.2%, add-on therapy users 1.3%). Non-persistent patients were 88.8% (35.3% occasional users, 20.6% stoppers, 32.8% intermittent users). Patient-related predictors of persistence were older age, male sex, concomitant treatment with antidiabetic and hypolipidaemic drugs and previous hospitalizations for cardiovascular events. Highest level of persistence was seen in patients starting with ARBs (18.8%), followed by ACE inhibitors (11.4%), β-blockers (11.0%), Ca(2+) antagonists (10.8%) and diuretics (3.0%). Among ARBs, considering separately monotherapy and fixed-combination therapy, highest level of persistence was observed in patients starting with candesartan, irbesartan, valsartan and telmisartan given in monotherapy, and with valsartan and

    In an integrated overview of the benefits and risks of menopausal hormone therapy (HT), the Women's Health Initiative (WHI) investigators have claimed that their 'findings … do not support use of this therapy for chronic disease prevention'. In an accompanying editorial, it was claimed that 'the WHI overturned medical dogma regarding menopausal [HT]'. To evaluate those claims. Epidemiological criteria of causation were applied to the evidence. A 'global index' purporting to summarize the overall benefit versus the risk of HT was not valid, and it was biased. For coronary heart disease, an increased risk in users of estrogen plus progestogen (E + P), previously reported by the WHI, was not confirmed. The WHI study did not establish that E+ P increases the risk of breast cancer; the findings suggest that unopposed estrogen therapy (ET) does not increase the risk, and may even reduce it. The findings for stroke and pulmonary embolism were compatible with an increased risk, and among E+ P users there were credible reductions in the risk of colorectal and endometrial cancer. For E+ P and ET users, there were credible reductions in the risk of hip fracture. Under 'worst case' and 'best case' assumptions, the changes in the incidence of the outcomes attributable to HT were minor. Over-interpretation and misrepresentation of the WHI findings have damaged the health and well-being of menopausal women by convincing them and their health professionals that the risks of HT outweigh the benefits.

    Several anti-hypertensive drugs have photosensitizing properties, however it remains unclear whether long-term users of these drugs are also at increased risk of skin malignancies. We conducted a literature review and meta-analysis on the association between use of anti-hypertensive drugs and the risk of cutaneous melanoma and non-melanoma skin cancer (NMSC). We searched PubMed, EMBASE, Google Scholar and the Cochrane Library, and included observational and experimental epidemiological studies published until February 28th, 2017. We calculated summary relative risk (SRR) and 95% confidence intervals (95% CI) through random effect models to estimate the risk of skin malignancies among users of the following classes of anti-hypertensive drugs: thiazide diuretics, angiotensin converting enzyme inhibitors (ACEi), angiotensin receptor blockers (ARB), calcium channel blockers (CCB) and β-blockers. We conducted sub-group and sensitivity analysis to explore causes of between-studies heterogeneity, and assessed publication bias using a funnel-plot based approach. Nineteen independent studies were included in the meta-analysis. CCB users were at increased skin cancer risk (SRR 1.14, 95% CI 1.07-1.21), and β-blockers users were at increased risk of developing cutaneous melanoma (SRR 1.21, 95% CI 1.05-1.40), with acceptable between-studies heterogeneity (I 2  skin cancer risk. We found no evidence of publication bias affecting the results. Family doctors and clinicians should inform their patients about the increased risk of skin cancer associated with the use of CCB and β-blockers and instruct them to perform periodic skin self-examination.

    Directory of Open Access Journals (Sweden)

    Wei Chen

    Full Text Available Abstract Background: Radiofrequency ablation of renal sympathetic nerve (RDN shows effective BP reduction in hypertensive patients while the specific mechanisms remain unclear. Objective: We hypothesized that abnormal levels of norepinephrine (NE and changes in NE-related enzymes and angiotensinconverting enzyme 2 (ACE2, angiotensin (Ang-(1-7 and Mas receptor mediate the anti-hypertensive effects of RDN. Methods: Mean values of systolic blood pressure (SBP, diastolic blood pressure (DBP and mean arterial pressure (MAP were assessed at baseline and follow-up. Plasma and renal norepinephrine (NE concentrations were determined using highperformance liquid chromatography with electrochemical detection, and levels of NE-related enzyme and ACE2-Ang(1-7- Mas were measured using real time PCR, Western blot and immunohistochemistry or Elisa in a hypertensive canine model fed with high-fat diet and treated with RDN. The parameters were also determined in a sham group treated with renal arteriography and a control group fed with normal diet. Results: RDN decreased SBP, DBP, MAP, plasma and renal NE. Compared with the sham group, renal tyrosine hydroxylase (TH expression was lower and renalase expression was higher in the RDN group. Compared with the control group, renal TH and catechol-o-methyl transferase (COMT were higher and renalase was lower in the sham group. Moreover, renal ACE2, Ang-(1-7 and Mas levels of the RDN group were higher than those of the sham group, which were lower than those of the control group. Conclusion: RDN shows anti-hypertensive effect with reduced NE and activation of ACE2-Ang(1-7-Mas, indicating that it may contribute to the anti-hypertensive effect of RDN.

    To document nurses' reported thinking processes during medication administration before and after implementation of point-of-care technology. Semistructured interviews and real-time tape recordings were used to document the thinking processes of 40 nurses practicing in inpatient care units in a large tertiary care teaching hospital in the northeastern US. Content analysis resulted in identification of 10 descriptive categories of nurses' thinking: communication, dose-time, checking, assessment, evaluation, teaching, side effects, work arounds, anticipating problem solving, and drug administration. Situations requiring judgment in dosage, timing, or selection of specific medications (e.g., pain management, titration of antihypertensives) provided the most explicit data about nurses' use of critical thinking and clinical judgment. A key element was nurses' constant professional vigilance to ensure that patients received their appropriate medications. Nurses' thinking processes extended beyond rules and procedures and were based on patient data and interdisciplinary professional knowledge to provide safe and effective care. Identification of thinking processes can help nurses to explain the professional expertise inherent in medication administration beyond the technical application of the "5 rights."

    Artemisia campestris L. (Asteraceae) has many traditional uses, among which treatment of diabetes and hypertension. This study was conducted in order to confirm the antihypertensive and hypotensive effects of A. campestris L. aqueous extract (AcAE) and to explore the underlying mechanism of action of its vasorelaxant effect, besides the acute toxicity. Also, the chemical composition of AcAE was investigated. the chemical content of AcAE was determined by using HPLC and NMR techniques. The antihypertensive effect was assessed indirectly by tail-cuff method on L-NAME induced hypertensive rats, while the hypotensive action was monitored intravenously by invasive method on normotensive rats. The vasorelaxant effect and vascular mechanism of action were studied in the presence of antagonists and blockers on aorta isolated from normotensive rats. On the other side, the acute toxicity was studied by oral feeding of extract to the mice. The global phytochemical profile of AcAE reveals the presence of several polyphenols as main components. A. campestris L. infusion was characterized by mono- and di-cinnamoyl compounds, with 3,5-dicaffeoylquinic (isochlorogenic A) acid being the main compound, followed by 5-caffeoylquinic (chlorogenic) acid. Vicenin-2 (apigenin 6,8-di-C-glucoside) appeared to be the most abundant compound among flavonoids. The daily treatment with AcAE at 150mg/kg/day prevented the installation of hypertension on L-NAME hypertensive rats, and reduced SBP from 172mmHg up to 144mmHg. At the dose 40mg/kg, AcAE provoked reduction of systolic (SBP), diastolic (DBP) and mean arterial pressure (MAP), without affecting the heart rate. Also, AcAE (10 -2 -2mg/ml) relaxed the precontracted aorta by 95.8±1.3%. The denudation and preincubation of aorta with atropine, calmidazolium, L-NAME, hydroxycobalamin, ODQ, 8-RP-Br-PET-cGMP, thapsigargin and verapamil attenuated the vasorelaxant response, while the pre-treatment with 4-AP, TEA, glibenclamide and BaCl 2 did not

    Full Text Available Janet B McGillDepartment of Medicine, Washington University School of Medicine, St. Louis, Missouri, USAAbstract: Hypertension is the number one diagnosis made by primary care physicians, placing them in a unique position to prescribe the antihypertensive agent best suited to the individual patient. In individuals with diabetes mellitus, blood pressure (BP levels > 130/80 mmHg confer an even higher risk for cardiovascular and renal disease, and these patients will benefit from aggressive antihypertensive treatment using a combination of agents. β‑blockers are playing an increasingly important role in the management of hypertension in high-risk patients. β‑blockers are a heterogeneous class of agents, and this review presents the differences between β‑blockers and provides evidence-based protocols to assist in understanding dose equivalence in the selection of an optimal regimen in patients with complex needs. The clinical benefits provided by β‑blockers are only effective if patients adhere to medication treatment long term. β‑blockers with proven efficacy, once-daily dosing, and lower side effect profiles may become instrumental in the treatment of hypertensive diabetic and nondiabetic patients.Keywords: antihypertensive, blood pressure, atenolol, carvedilol, labetalol, metoprolol, nebivolol

    Full Text Available In today’s healthcare, the role of morality emerges to the forefront as a result of the high degree of uncertainty in our modern environment. Ethically responsible behaviour is therefore perceived as a prerequisite for preventing and counteracting a number of moral risks in society. With regard to moral hazard and responsibility, ethical codes represent a rational control mechanism, lowering the extent of the probability of moral peril. Ethics committees are also founded based on such ethical codes, the purpose of such committees being the proclamation and observation of the principles and norms set forth. At the healthcare institutions of the Republic of Bulgaria, ethics committees are established that are based on the principles of medical ethics and medical law. The significance with which ethics committees are charged regarding the sustainable development of the healthcare system consists of protecting the patients, the medical professionals and the institution itself. Awareness of the significance, functions and benefits of ethics committees and their impact on the medical practice and patients in Bulgaria is, however, insufficiently low. In a questionnaire survey conducted among 149 medical specialists employed at three medical establishments for hospital care in the country, and 269 patients under treatment at them, at being asked “Do you think that ethics committees contribute to protecting and respecting patients’ rights?”, 26.2% of the respondents among the medical professionals replied that they are not sure, while 25.7% of did not provide an answer to the question thus asked due to being unfamiliar with ethics committees as an institutionalized body and their functions. The analysis of the results of the abovementioned survey among medical professionals and patients evidences a low level of awareness of the ethics committees and their work on the territory of the Republic of Bulgaria. It is essential for healthcare

    Self-report scales are used to assess medication adherence. Data on how to discriminate change in self-reported adherence over time from random variability are limited. To determine the minimal detectable change for scores on the 8-item Morisky Medication Adherence Scale (MMAS-8). The MMAS-8 was administered twice, using a standard telephone script, with administration separated by 14-22 days, to 210 participants taking antihypertensive medication in the CoSMO (Cohort Study of Medication Adherence among Older Adults). MMAS-8 scores were calculated and participants were grouped into previously defined categories (<6, 6 to <8, and 8 for low, medium, and high adherence). The mean (SD) age of participants was 78.1 (5.8) years, 43.8% were black, and 68.1% were women. Overall, 8.1% (17/210), 16.2% (34/210), and 51.0% (107/210) of participants had low, medium, and high MMAS-8 scores, respectively, at both survey administrations (overall agreement 75.2%; 158/210). The weighted κ statistic was 0.63 (95% CI 0.53 to 0.72). The intraclass correlation coefficient was 0.78. The within-person standard error of the mean for change in MMAS-8 scores was 0.81, which equated to a minimal detectable change of 1.98 points. Only 4.3% (9/210) of the participants had a change in MMAS-8 of 2 or more points between survey administrations. Within-person changes in MMAS-8 scores of 2 or more points over time may represent a real change in antihypertensive medication adherence.

    The economic impact of pharmacist-managed antiarrhythmic drug therapy monitoring on an academic medical center's electrophysiology (EP) program was investigated. Data were collected for the initial two years of patient visits (n = 816) to a pharmacist-run clinic for antiarrhythmic drug therapy monitoring. A retrospective cost analysis was conducted to assess the direct costs associated with three appointment models: (1) a clinic office visit only, (2) a clinic visit involving electrocardiography and basic laboratory tests, and (3) a clinic visit including pulmonary function testing and chest x-rays in addition to electrocardiography and laboratory testing. A subset of patient cases (n = 18) were included in a crossover analysis comparing pharmacist clinic care and usual care in an EP physician clinic. The primary endpoints were the cost benefits and cost savings associated with pharmacy-clinic care versus usual care. A secondary endpoint was improvement of overall EP program efficiency. The payer mix was 61.6% (n = 498) Medicare, 33.2% (n = 268) managed care, and 5.2% (n = 42) other. Positive contribution margins were demonstrated for all appointment models. The pharmacist-managed clinic also yielded cost savings by reducing overall patient care charges by 21% relative to usual care. By the second year, the pharmacy clinic improved EP program efficiency by scheduling an average of 24 patients per week, in effect freeing up one day per week of EP physician time to spend on other clinical activities. Pharmacist monitoring of antiarrhythmic drug therapy in an out-patient clinic provided cost benefits, cost savings, and improved overall EP program efficiency.

    Full Text Available In Mexico black cherry (Prunus serotina Ehrh. fruits are consumed fresh, dried or prepared in jam. Considering the evidence that has linked intake of fruits and vegetables rich in polyphenols to cardiovascular risk reduction, the aim of this study was to characterize the phenolic profile of black cherry fruits and to determine their antioxidant, vasorelaxant and antihypertensive effects. The proximate composition and mineral contents of these fruits were also assessed. Black cherry fruits possess a high content of phenolic compounds and display a significant antioxidant capacity. High-performance liquid chromatography/mass spectrometric analysis indicated that hyperoside, anthocyanins and chlorogenic acid were the main phenolic compounds found in these fruits. The black cherry aqueous extract elicited a concentration-dependent relaxation of aortic rings and induced a significant reduction on systolic blood pressure in L-NAME induced hypertensive rats after four weeks of treatment. Proximate analysis showed that black cherry fruits have high sugar, protein, and potassium contents. The results derived from this study indicate that black cherry fruits contain phenolic compounds which elicit significant antioxidant and antihypertensive effects. These findings suggest that these fruits might be considered as functional foods useful for the prevention and treatment of cardiovascular diseases.

    Blood pressure (BP) can differ substantially when measured in the clinic versus outside of the clinic setting. Few population-based studies with ambulatory blood pressure monitoring (ABPM) include African Americans. We calculated the prevalence of clinic hypertension and ABPM phenotypes among 1,016 participants in the population-based Jackson Heart Study, an exclusively African-American cohort. Mean daytime systolic BP was higher than mean clinic systolic BP among participants not taking antihypertensive medication (127.1[standard deviation 12.8] versus 124.5[15.7] mmHg, respectively) and taking antihypertensive medication (131.2[13.6] versus 130.0[15.6] mmHg, respectively). Mean daytime diastolic BP was higher than clinic diastolic BP among participants not taking antihypertensive medication (78.2[standard deviation 8.9] versus 74.6[8.4] mmHg, respectively) and taking antihypertensive medication (77.6[9.4] versus 74.3[8.5] mmHg, respectively). The prevalence of daytime hypertension was higher than clinic hypertension for participants not taking antihypertensive medication (31.8% versus 14.3%) and taking antihypertensive medication (43.0% versus 23.1%). A high percentage of participants not taking and taking antihypertensive medication had nocturnal hypertension (49.4% and 61.7%, respectively), white coat hypertension (30.2% and 29.3%, respectively), masked hypertension (25.4% and 34.6%, respectively), and a non-dipping BP pattern (62.4% and 69.6%, respectively). In conclusion, these data suggest hypertension may be misdiagnosed among African Americans without using ABPM. PMID:28285829

    Full Text Available The agonists of imidazoline I-1 receptors (I-1R are widely used to lower blood pressure. It has been indicated that guanidinium derivatives show an ability to activate imidazoline receptors. Also, allantoin has a chemical stricture similar to guanidinium derivatives. Thus, it is of special interest to characterize the effect of allantoin on I-1R. In conscious male spontaneous hypertensive rats (SHRs, mean blood pressure (MBP was recorded using the tail-cuff method. Furthermore, the hemodynamic analyses in catheterized rats were applied to measure the actions of allantoin in vivo. Allantoin decreased blood pressures in SHRs at 30 minutes, as the most effective time. Also, this antihypertensive action was shown in a dose-dependent manner from SHRs treated with allantoin. Moreover, in anesthetized rats, allantoin inhibited cardiac contractility and heart rate as showing in hemodynamic dP/dt max significantly. Also, the peripheral blood flow was markedly increased by allantoin. Both actions were diminished by efaroxan at the dose sufficient to block I-1R. Thus, we suggest that allantoin, as I-1R agonist, has the potential to develop as a new therapeutic agent for hypertension in the future.

    One of the methods of identifying core and popular resources is by citation evaluation. Using citation evaluation, the librarians of the Acquisition Department can use quantitative methods to indentify core and popular resources among numerous information resources and make serious savings in the library's budget, by acquiring these core resources and eliminating useless ones. The aim of this study is assessing literature obsolescence and core journals' cost-benefit in citations of the 'Scientific Medical Journal of Ahwaz'. This study is a descriptive and cross-sectional survey that uses citation analysis. Sampling is objective sampling from all documents from years 1364 (1985) to 1385 (2006), and the population comprises of 6342 citations of the articles published in 'Scientific Medical Journal of Ahwaz'. Data collection is done through referring to the original documents and the data is analyzed using the Excel software, and for descriptive and analytical statistics the cost-benefit formula and Bradford law formula are used. Findings showed that the average citation for each document in the 'Scientific Medical Journal of Ahwaz' was 15.81. The average citation to international sources was 14.37, and the average citation to national sources was 1.44. The literature obsolescence of Farsi documents in this study was 15 years, while it was equal to 20 years for English documents. The highly cited Farsi journals were (sorted based on citation in descending order): 'Scientific Medical Journal of Ahwaz', 'Daroudarman', 'Nabz,' and 'Journal of Medical School, Shahid Beheshti University of Medical Sciences'. The highly cited English journals were (sorted based on citation in descending order): 'Pediatrics', 'The New England Journal of Medicine', 'Gastroenterology' and 'Medicine'. All of these four journals are part of the ISI database and have good impact factors in the Journal Citation Reports (JCR). Also their cost-benefit was reasonable based on the frequency of their

    Conventional print materials for presenting risks and benefits of treatment are often difficult to understand. This study was undertaken to evaluate and compare subjects' understanding and perceptions of risks and benefits presented using animated computerized text and graphics. Adult subjects were randomized to receive identical risk/benefit information regarding taking statins that was presented on an iPad (Apple Corp, Cupertino, Calif) in 1 of 4 different animated formats: text/numbers, pie chart, bar graph, and pictograph. Subjects completed a questionnaire regarding their preferences and perceptions of the message delivery together with their understanding of the information. Health literacy, numeracy, and need for cognition were measured using validated instruments. There were no differences in subject understanding based on the different formats. However, significantly more subjects preferred graphs (82.5%) compared with text (17.5%, Pbenefits offer an effective means to describe medical risk/benefit statistics. That understanding and satisfaction were significantly better when the format matched the individual's preference for message delivery is important and reinforces the value of "tailoring" information to the individual's needs and preferences.

    To study whether the dose of controlling antihypertensive drug is reduced by transcutaneous electrical acupoint stimulation (TEAS) and the anesthetics, as well as the control of blood pressure (BP) and heart rate (HR) in endoscopic endonasal surgery with general anesthesia. Sixty patients for selective endoscopic endonasal surgery with general anesthetics and controlling antihypertension involved were selected and randomized into a TEAS group, a sham-TEAS group, 30 cases in each one. The electric pads were attached to bilateral Hegu (LI 4), Zusanli (ST 36), Sanyinjiao (SP 6) and Quchi (LI 11), stimulated with Hans-200 apparatus, 3 to 5 mA, 2 Hz/100 Hz in the TEAS group based on the patients' response to comfort. No electric stimulation was applied to the sham-TEAS group. The general anesthesia started after 30 min intervention and lasted till the end of surgery. The BP and HR were observed and recorded at the end of monitoring in operation room, 10 min after tranquilization (T0), 30 min after intervention (Tj, after induction~of general anestiesa (T2), 30 min after surgery start (T3), 60 min after surgery start (T4) and 30 min after extubation (T5). The doses of vecuronium bromide, propofol and nitroglycerin were recorded statistically in surgery, as well as the operative bleeding volume, the operative time, the resuscitation time and the visual analogue scale (VAS) score after resuscitation. Compared with that at T0, the mean arterial pressure (MAP) at T2, T3, T4 and T5 in the TEAS group and at T3 and T4 in the sham-TEAS group was all reduced, indicating the significant difference (all P 0.05). HR was different at T2 to Ts in the sham-TEAS group statistically (all P 0.05). The general anesthesia with TEAS and anesthetics involved for controlling antihypertension contributes to the control of BP and HR in the patients in endoscopic endonasal surgery. The impacts are not obvious on the doses of antihypertensive drug, the general anesthetics, the operative bleeding

    Over one-quarter of the world's adult population has hypertension, yet achieving adequate treatment or control targets remains a challenge. This study sought to identify, longitudinally, characteristics associated with antihypertensive treatment and blood pressure (BP) control among individuals with hypertension. Data from individuals enrolled in the population-based CRONICAS Cohort Study (adults ≥35 years, living in 4 different rural/urban and coastal/high-altitude Peruvian settings) with hypertension at baseline were used. Antihypertensive treatment and BP control were assessed at baseline and at 15 months. Multinomial logistic regressions were used to estimate relative risk ratios (RRR) and 95% confidence intervals (95% CI) of factors associated with antihypertensive treatment and BP control at follow-up. At baseline, among 717 individuals with hypertension (53% women, mean age 61.5 ± 12.4 years), 28% were unaware of their hypertension status, 30% were aware but untreated, 16% were treated but uncontrolled, and 26% were treated and controlled. At follow-up, 89% of unaware and 82% of untreated individuals persisted untreated, and only 58% of controlled individuals remained controlled. Positive predictors of receiving treatment and being controlled at follow-up included age (RRR: 0.81; 95% CI: 0.73 to 0.91 for every 5 years) and family history of a chronic disease (RRR: 0.53; 95% CI: 0.31 to 0.92 vs. no history); whereas Puno rural site (RRR: 16.51; 95% CI: 1.90 to 143.56 vs. Lima) and male sex (RRR: 2.59; 95% CI: 1.54 to 4.36) were risk factors. Systolic BP at baseline (RRR: 1.27; 95% CI: 1.16 to 1.39 for every 5 mm Hg) and male sex (RRR: 1.75, 95% CI: 1.02 to 2.98) were risk factors for being treated but uncontrolled at follow-up. Large gaps in treatment of hypertension were observed. Targeting specific populations such as men, younger individuals, or those without family history of disease may increase coverage of antihypertensive treatment. Also, targeting

    To assess the effect of a lifestyle intervention in lowering/normalizing blood pressure (BP) levels in hypertensive (controlled or not) obese patients. In this prospective observational study, 490 obese hypertensive patients, 389 controlled (BP < 140/90 mm Hg; CH) and 101 uncontrolled (BP ≥ 140/90 mm Hg; UH) attended a 3-month lifestyle intervention. Before and after the intervention we assessed weight, waist circumference, fat mass, BP, metabolic and renal variables, and physical activity. A multivariate regression model was used to determine the predictors of BP changes. 18.9% of CH and 20.0% of UH were on ≥ 3 antihypertensive drugs. Weight change (average -4.9 ± 2.7%) was independent of the antihypertensive drugs employed. Systolic BP (SBP) decreased by 23 mm Hg and diastolic BP (DBP) by 9 mm Hg, in patients with UH most of whom (89%) normalized BP levels (in 49% after a weight loss < 5%). Age, gender, whole and central obesity, concomitance of type 2 diabetes, chronic renal disease, physical activity intensification, and pharmacological therapy did not affect BP lowering. In the regression analysis with SBP change as dependent variable, weight reduction (β = 0.523, p = 0.005) and group (UH vs. CH, β = -19.40, p = 0.0005) remained associated with SBP reduction. When DBP change was entered as dependent variable, baseline uric acid remained associated with DBP reduction (β = 0.824, p < 0.05). Lifestyle interventions are useful for all obese hypertensive patients in most of whom a modest weight loss is sufficient to normalize BP levels avoiding the aggressive use of multiple antihypertensive drugs. © 2016 The Author(s) Published by S.

    BACKGROUND: Despite the availability of a variety of effective drugs, inadequate control of blood pressure is common. There are some indications that the angiotensin-converting enzyme (ACE) gene modifies the response to antihypertensive drugs, but the results have been inconclusive. OBJECTIVE: To

    Full Text Available Background: Some species of Allium family are known to have antihypertensive, anti-diabetic, and lipid lowering effects. Objectives: This study aimed to examine the possible mechanisms of antihypertensive, anti-diabetic, and anti-lipid activities of Allium eriophyllum which grows in Fars province, Iran in a rat model of simultaneous type 2 diabetes and renal hypertension. Materials and Methods: This study was conducted on six groups of male Spargue-Dawley rats each containing 8 - 10 animals, including a sham-control, a diabetic, a renal hypertensive, and three simultaneously hypertensive–diabetic groups receiving vehicle or 30 or 100 mg/kg/day hydroalcoholic extract of Allium eriophyllum. Four weeks after induction of diabetes, renal hypertension was induced and the animals started receiving the vehicle or extract for the subsequent four weeks. Afterwards, blood pressure, fasting blood sugar, serum cholesterol, triglyceride, and markers of oxidative stress were measured, and isolated studies were performed on aortic rings. Results: Systolic blood pressure, heart rate, fasting blood sugar, maximal response, and effective concentrations 50 (EC50 of phenylephrine and acetylcholine of the hypertensive-diabetic group receiving vehicle were significantly higher compared to those of the sham-control group, and treatment with the extract led to a significant reduction in these variables. Moreover, serum superoxide dismutase and glutathione reductase and maximal response of acetylcholine were significantly lower in the hypertensive-diabetic group receiving vehicle in comparison to the sham-control group, and treatment with the extract significantly reduced these variables. Conclusions: The present study findings indicated that antihypertensive, anti-diabetic, and anti-lipid effects of the extract might be partly due to its antioxidant mechanism. It was also revealed that its antihypertensive effects may be additionally mediated by improving the release

    Full Text Available This study aimed to evaluate the antihypertensive efficacy of a new combination therapy of Hibiscus sabdariffa and Olea europaea extracts (2 : 1; Roselle-Olive, using N(G-nitro-L-arginine-methyl ester- (L-NAME- induced hypertensive model. Rats received L-NAME (50 mg/kg/day, orally for 4 weeks. Concurrent treatment with Roselle-Olive (500, 250, and 125 mg/kg/day for 4 weeks resulted in a dose-dependent decrease in both systolic and diastolic blood pressure, reversed the L-NAME-induced suppression in serum nitric oxide (NO, and improved liver and kidney markers, lipid profile, and oxidative status. Furthermore, Roselle-Olive significantly lowered the elevated angiotensin-converting enzyme activity (ACE and showed a marked genoprotective effect against oxidative DNA damage in hypertensive rats. Roselle-Olive ameliorated kidney and heart lesions and reduced aortic media thickness. Real-time PCR and immunohistochemistry showed an enhanced endothelial nitric oxide synthase (eNOS gene and protein expression in both heart and kidney of Roselle-Olive-treated rats. To conclude, our data revealed that Roselle-Olive is an effective combination in which H. sabdariffa and O. europaea synergistically act to control hypertension. These effects are likely to be mediated by antioxidant and genoprotective actions, ACE inhibition, and eNOS upregulation by Roselle-Olive constituents. These findings provide evidences that Roselle-Olive combination affords efficient antihypertensive effect with a broad end-organ protective influence.

    Anthony S Gunnell

    Full Text Available BACKGROUND: Lifestyle factors have been implicated in ischaemic heart disease (IHD development however a limited number of longitudinal studies report results stratified by cardio-protective medication use. PURPOSE: This study investigated the influence of self-reported lifestyle factors on hospitalisation for IHD, stratified by blood pressure and/or lipid-lowering therapy. METHODS: A population-based cohort of 14,890 participants aged 45+ years and IHD-free was identified from the Western Australian Health and wellbeing Surveillance System (2004 to 2010 inclusive, and linked with hospital administrative data. Adjusted hazard ratios for future IHD-hospitalisation were estimated using Cox regression. RESULTS: Current smokers remained at higher risk for IHD-hospitalisation (adjusted HR=1.57; 95% CI: 1.22-2.03 after adjustment for medication use, as did those considered overweight (BMI=25-29 kg/m(2; adjusted HR=1.28; 95% CI: 1.04-1.57 or obese (BMI of ≥30 kg/m(2; adjusted HR=1.31; 95% CI: 1.03-1.66. Weekly leisure-time physical activity (LTPA of 150 minutes or more and daily intake of 3 or more fruit/vegetable servings reduced risk by 21% (95% CI: 0.64-0.97 and 26% (95% CI: 0.58-0.96 respectively. Benefits of LTPA appeared greatest in those on blood pressure lowering medication (adjusted HR=0.50; 95% CI: 0.31-0.82 [for LTPA=150 mins]. IHD risk in smokers was most pronounced in those taking neither medication (adjusted HR=2.00; 95% CI: 1.41-2.83. CONCLUSION: This study confirms the contribution of previously reported lifestyle factors towards IHD hospitalisation, even after adjustment for antihypertensive and lipid-lowering medication use. Medication stratified results suggest that IHD risks related to LTPA and smoking may differ according to medication use.

  20. Electronic medical record systems in critical access hospitals: leadership perspectives on anticipated and realized benefits.

    2010-04-01

    The growth of electronic medical records (EMRs) is driven by the belief that EMRs will significantly improve healthcare providers' performance and reduce healthcare costs. Evidence supporting these beliefs is limited, especially for small rural hospitals. A survey that focused on health information technology (HIT) capacity was administered to all hospitals in Iowa. Structured interviews were conducted with the leadership at 15 critical access hospitals (CAHs) that had implemented EMRs in order to assess the perceived benefits of operational EMRs. The results indicate that most of the hospitals implemented EMRs to improve efficiency, timely access, and quality. Many CAH leaders also viewed EMR implementation as a necessary business strategy to remain viable and improve financial performance. While some reasons reflect external influences, such as perceived future federal mandates, other reasons suggest that the decision was driven by internal forces, including the hospital's culture and the desires of key leaders to embrace HIT. Anticipated benefits were consistent with goals; however, realized benefits were rarely obvious in terms of quantifiable results. These findings expand the limited research on the rationale for implementing EMRs in critical access hospitals.

  1. Framing Service, Benefit, and Credibility Through Images and Texts: A Content Analysis of Online Promotional Messages of Korean Medical Tourism Industry.

    2016-07-01

    This study examines how the Korean medical tourism industry frames its service, benefit, and credibility issues through texts and images of online brochures. The results of content analysis suggest that the Korean medical tourism industry attempts to frame their medical/health services as "excellence in surgeries and cancer care" and "advanced health technology and facilities." However, the use of cost-saving appeals was limited, which can be seen as a strategy to avoid consumers' association of lower cost with lower quality services, and to stress safety and credibility.

    Local food diversity and traditional crops are essential for cost-effective management of the global epidemic of type 2 diabetes and associated complications of hypertension. Water and 12% ethanol extracts of native Peruvian fruits such as Lucuma (Pouteria lucuma), Pacae (Inga feuille), Papayita arequipeña (Carica pubescens), Capuli (Prunus capuli), Aguaymanto (Physalis peruviana), and Algarrobo (Prosopis pallida) were evaluated for total phenolics, antioxidant activity based on 2, 2-diphenyl-1-picrylhydrazyl radical scavenging assay, and functionality such as in vitro inhibition of alpha-amylase, alpha-glucosidase, and angiotensin I-converting enzyme (ACE) relevant for potential management of hyperglycemia and hypertension linked to type 2 diabetes. The total phenolic content ranged from 3.2 (Aguaymanto) to 11.4 (Lucuma fruit) mg/g of sample dry weight. A significant positive correlation was found between total phenolic content and antioxidant activity for the ethanolic extracts. No phenolic compound was detected in Lucuma (fruit and powder) and Pacae. Aqueous extracts from Lucuma and Algarrobo had the highest alpha-glucosidase inhibitory activities. Papayita arequipeña and Algarrobo had significant ACE inhibitory activities reflecting antihypertensive potential. These in vitro results point to the excellent potential of Peruvian fruits for food-based strategies for complementing effective antidiabetes and antihypertension solutions based on further animal and clinical studies.

    Antihypertensive drugs action should last at least 24 h in order to enhance adherence, with positive impact on CV morbimortality. ABPM allow us to evaluate duration of action of drugs, against placebo, using Trough:Peak Ratio, antihypertensive effect in the last 4 h interdosis, and calculating the rate of BP morning surge. Losartán is an Antagonist At1 with good antihypertensive efficacy and renal, cardiac and cerebrovascular protection. Some studies shows less than 24 hs of action, that suggest twice a day dosing. The merge of a new formulation, Losartan Cronos, a bilayer tablet containing 50 mg of Losartan immediate release (IR) and 50 mg extended release (ER) would allow 24 h coverage, maintaining the previous advantages. To assess antihypertensive duration of action of Losartán Cronos in patients with essential hypertension throughout a 24-h dosing interval, using ABPM and response rates, AASI and Smoothness Index. 97 essential hypertensives, where included and received a single morning dose of Losartán Cronos (50 mg of regular release and 50 mg of controlled and retarded release) during 8 weeks. Performed valid ABPM post placebo and post active treatment. Results Mean age 58 (26-86), 60% women. 63% treatment naïve. The mean reduction in BP from baseline to week 8 (end of treatment) was statistically significant for all times analyzed (24 hours, daytime, night-time, and last 4 hours monitoring). There were no significant changes in 24h heart rate. BP morning surge (mmHg/hour) decreased from 4.53 to 3,68 (p=0.03).T:P Ratio was 0.91 for SBP and 1.14 for DBP. Smoothness Index: SBP 2.86 (95% CI 1.84-3.7) - DBP 3.17 (95% CI 2.03-3.9) 19 patients had adverse events, no-one cough, all mild, without discontinuations. Conclusion Losartán Cronos demonstrated efficacy and safety, decreases BP without significant effects in heart rate, it reduces the pulse pressure, and its effect lasts for 24 hs, assessed by T:P ratio, last 4 hours effects, decreasing morning surge

    The Chemical Terrorism Risk Assessment (CTRA) and Chemical Infrastructure Risk Assessment (CIRA) are programs that estimate the risk of chemical terrorism attacks to help inform and improve the US defense posture against such events. One aspect of these programs is the development and advancement of a Medical Mitigation Model-a mathematical model that simulates the medical response to a chemical terrorism attack and estimates the resulting number of saved or benefited victims. At the foundation of the CTRA/CIRA Medical Mitigation Model is the concept of stock-and-flow modeling; "stocks" are states that individuals progress through during the event, while "flows" permit and govern movement from one stock to another. Using this approach, the model is able to simulate and track individual victims as they progress from exposure to an end state. Some of the considerations in the model include chemical used, type of attack, route and severity of exposure, response-related delays, detailed treatment regimens with efficacy defined as a function of time, medical system capacity, the influx of worried well individuals, and medical countermeasure availability. As will be demonstrated, the output of the CTRA/CIRA Medical Mitigation Model makes it possible to assess the effectiveness of the existing public health response system and develop and examine potential improvement strategies. Such a modeling and analysis capability can be used to inform first-responder actions/training, guide policy decisions, justify resource allocation, and direct knowledge-gap studies.

    2007-01-01

    Full Text Available Scientific background: Poor compliance or adherence in drug therapy can cause increased morbidity, mortality and enormous costs in the healthcare system (in Germany annually approximately 10 billion euros. Different methods are used for enhancing the compliance or adherence. Research questions: The evaluation addresses the questions about existence, efficacy, cost-benefit relation as well as ethical-social and juridical implications of strategies for enhancing compliance or adherence in drug therapy with concomitant improvements in treatment outcomes. Methods: A systematic literature search was conducted in the medical, also health economic relevant, literature databases in January 2007, beginning from 2002. Systematic reviews on the basis of (randomised controlled trials (RCT concerning interventions to enhance compliance or adherence with regard to treatment outcomes as well as systematic reviews of health economic analyses were included in the evaluation. Additionally, it was also searched for publications which primarily considered ethical-social and juridical aspects of these interventions for the German context. Results: One systematic review with data for 57 RCT was included in the medical evaluation and one systematic review with data for six studies into the health economic evaluation. No publication primary concerning ethical-social or juridical implications could be identified. A significant positive effect on the treatment outcome was reported for 22 evaluated interventions. For many interventions the results can be classified as reliable: counseling with providing an information leaflet and compliance diary chart followed by phone consultation for helicobacter pylori positive patients, repeated counseling for patients with acute asthma symptoms, telephone calls to establish the level of compliance and to make recommendations based on that for the therapy of cardiovascular diseases, calls of an automated telephone system with phone

  1. Antihypertensive activity of 80% methanol seed extract of Calpurnia aurea (Ait.) Benth. subsp. aurea (Fabaceae) is mediated through calcium antagonism induced vasodilation.

    2016-08-02

    Calpurnia aurea (Ait.) Benth. subsp. aurea (CASA) (Fabaceae) seeds are used to treat hypertension in Ethiopian folklore medicine, particularly by Shinasha, Agew-awi and Amhara people in northwest Ethiopia. However, the claim has so far not been substantiated scientifically. The study was conducted to evaluate the antihypertensive activity of 80% methanol extract of CASA in animal model of hypertension as well as its vasorelaxant effect and possible underlying mechanisms in isolated guinea pig aorta. Hypotensive and antihypertensive effect of CASA extract was determined in vivo through the intravenous (iv) route in normotensive and hypertensive anesthetized rats using 2-kidney-1-clip (2K1C) rat model. Ex vivo, guinea pig thoracic aortic rings were isolated and suspended in organ bath, and the vasodepressor effects as well as the mechanism of action of the extract were studied by means of isometric tension recording experiments. The blood pressure fell dose-dependently and significantly in renal hypertensive and normotensive rats following i.v. administration, suggesting that the hydroalcoholic extract possesses hypotensive and antihypertensive effects. The extract also caused a dose-dependent relaxation of aorta pre-contracted with KCl at a concentration of 5-250mg/L, with a maximum relaxation of 92.1% achieved at 250mg/L. The relaxation mechanism was found to be independent of the muscarinic receptors, histamine receptors, ATP dependent K(+) channels, cyclooxygenase enzymes, cGMP/NO pathway and the endothelium system. The extract caused rightward shift of the Ca(++) dose-response curves, similar to that caused by verapamil, indicating that it produced vasorelaxation by inhibiting extracellular Ca(2+) influx. The findings demonstrate that the plant is endowed with antihypertensive effect, providing evidence for its traditional use. The effect may be, at least in part, due to dilation of blood vessels through blockage of Ca(2+) channels. Copyright © 2016 Elsevier

    We reported that yam dioscorin and its peptic hydrolysates exhibited ACE inhibition and antihypertensive effects on SHRs, however, the active peptides are not really isolated until now. Using ACE inhibitory screenings, two penta-peptides, KTCGY and KRIHF, were selected for ex vivo and in vivo experiments. KTCGY, KRIHF, and captopril were shown to have similar vasodilating effects against phenylephrine (PE)-induced tensions in rat endothelium-dependent thoracic aortic rings, however, KTCGYKTCGY (two-repeated KTCGY) and TCGYTCGY (two-repeated TCGY) were showed endothelium-independent vasodilating effects against PE-induced tensions. KTCGY, KRIHF (10 or 20 mg/kg), and captopril (10 mg/kg) were used to evaluate antihypertensive activity during 24-h after a single oral administration to spontaneously hypertensive rats (SHRs). The KTCGY and KRIHF showed significantly different and reduced the systolic blood pressure of SHRs compared to the blank. These results suggest that KTCGY and KRIHF may contribute important roles in yam dioscorin for regulating blood pressure in vivo.

Patients with metabolic syndrome had significantly poorer regional cerebral blood flow compared with control group: by 7% (P = 0.003) in right anterior parietal cortex, by 6% (P = 0.028) in left anterior parietal cortex, by 8% (P = 0.007) in right superior frontal lobe, and by 10% (P = 0.00002) and 7% (P = 0.006) in right and left temporal brain regions, correspondingly. The results of neuropsychological testing showed 11% decrease in mentation (P = 0.002), and 19% (P = 0.011) and 20% (P = 0.009) decrease in immediate verbal and visual memory in patients with MetS as compared with control group. Relationships between the indices of ABPM, cerebral perfusion, and cognitive function were found. Data showed an improvement of regional cerebral blood flow, ABPM parameters, and indicators of cognitive functions after 6 months of antihypertensive therapy in patients with MetS. The study showed the presence of diffuse disturbances in cerebral perfusion is associated with cognitive disorders in patients with metabolic syndrome. Combination antihypertensive treatment exerts beneficial effects on the 24-h blood pressure profile, increases cerebral blood flow, and improves cognitive function in patients with MetS. © 2015 John Wiley & Sons Ltd.

  4. Micellar Enhanced Three-Dimensional Excitation-Emission Matrix Fluorescence for Rapid Determination of Antihypertensives in Human Plasma with Aid of Second-Order Calibration Methods

    Full Text Available A highly sensitive three-dimensional excitation-emission fluorescence method was proposed to determine antihypertensives including valsartan and amlodipine besylate in human plasma with the aid of second-order calibration methods based on parallel factor analysis (PARAFAC and alternating trilinear decomposition (ATLD algorithms. Antihypertensives with weak fluorescent can be transformed into a strong fluorescent property by changing microenvironment in samples using micellar enhanced surfactant. Both the adopted algorithms with second-order advantage can improve the resolution and directly attain antihypertensives concentration even in the presence of potential strong intrinsic fluorescence from human plasma. The satisfactory results can be achieved for valsartan and amlodipine besylate in complicated human plasma. Furthermore, some statistical parameters and figures of merit were evaluated to investigate the performance of the proposed method, and the accuracy and precision of the proposed method were also validated by the elliptical joint confidence region (EJCR test and repeatability analysis of intraday and interday assay. The proposed method could not only light a new avenue to directly determine valsartan or amlodipine besylate in human plasma, but also hold great potential to be extended as a promising alternative for more practical applications in the determination of weak fluorescent drugs.

    Electronic medical records (EMR) can be a cost-effective source for hypertension surveillance. However, diagnosis of hypertension in EMR is commonly under-coded and warrants the needs to review blood pressure and antihypertensive drugs for hypertension case identification. We included all the patients actively registered in The Health Improvement Network (THIN) database, UK, on 31 December 2011. Three case definitions using diagnosis code, antihypertensive drug prescriptions and abnormal blood pressure, respectively, were used to identify hypertension patients. We compared the prevalence and treatment rate of hypertension in THIN with results from Health Survey for England (HSE) in 2011. Compared with prevalence reported by HSE (29.7%), the use of diagnosis code alone (14.0%) underestimated hypertension prevalence. The use of any of the definitions (38.4%) or combination of antihypertensive drug prescriptions and abnormal blood pressure (38.4%) had higher prevalence than HSE. The use of diagnosis code or two abnormal blood pressure records with a 2-year period (31.1%) had similar prevalence and treatment rate of hypertension with HSE. Different definitions should be used for different study purposes. The definition of 'diagnosis code or two abnormal blood pressure records with a 2-year period' could be used for hypertension surveillance in THIN. © The Author 2015.

    2011-01-01

    Full Text Available Loranthus micranthus (LM, also called African mistletoe is a major Nigerian Loranthaceae plant used traditionally to treat hypertension. The methanolic leaf extract of the plant (LMME has been shown to elicit anti-hypertensive activity in rats but mechanism remains unclear. This study was undertaken to study the effect of LM on pressor-induced contraction of rat aorta smooth muscles and serum lipid profiles in mice. The LMME was partitioned to produce n-butanol (NBF-LMME, chloroform (CF-LMME, ethyl acetate (EAF-LMME and water (WF-LMME fractions. The median effective concentrations and maximum relaxation of the fractions were determined against epinephrine and KCl pre-contracted rat aorta ring model. Serum lipid profiles and nitric oxide (NO were determined spectrophotometrically in mice administered per orally 250 mg/kg b.w. of each fraction for 21 days. Data were analyzed statistically. NBF-LMME elicited the highest dose-dependent inhibitory effect on rat aorta pre-contracted with norepinephrine and KCl, followed in decreasing order by WF-LMME > CF-LMME > EAF-LMME. Similar order of activity was observed in the ability of these fractions to inhibit elevation in artherogenic lipids, raise serum nitric oxide and reduce cardiac arginase in mice. We conclude the anti-hypertensive activity of L. micranthus involve anti-artherogenic events, vasorelaxation, cardiac arginase reduction and NO elevation.

    Abstract Background As the case detection rates of hypertension increase in adult Nigerians, achieving target blood pressure (BP) control has become an important management challenge. Objectives To describe medication adherence and BP control amongst adult Nigerians with primary hypertension attending a primary care clinic of a tertiary hospital in a resource-poor environment in Eastern Nigeria. Methods A cross-sectional study was carried out in 140 adult patients with primary hypertension who have been on treatment for at least 6 months at the primary care clinic of Federal Medical Centre, Umuahia. A patient was said to have achieved goal BP control if the BP was < 140 per 90 mmHg. Adherence was assessed in the previous 30 days using a pretested researcher-administered questionnaire on 30 days of self-reported therapy. Adherence was graded using an ordinal scoring system of 0–4; an adherent patient was one who scored 4 points in the previous 30 days. Reasons for non-adherence were documented. Results Adherence to medication and BP control rates were 42.9% and 35.0% respectively. BP control was significantly associated with medication adherence (p = 0.03), antihypertensive medication duration ≥3 years (p = 0.042), and taking ≥ one form of antihypertensive medication (p = 0.04). BP at the recruitment visit was significantly higher than at the end of the study (p = 0.036). The most common reason for non-adherence was forgetfulness (p = 0.046). Conclusions The rate of BP control amongst the study population was low, which may be connected with low medication adherence. This study urges consideration of factors relating to adherence alongside other factors driving goal BP control.

    Diabetes mellitus is a growing in exponential proportions. If the current growth trend continues, it may result in every third adult in the United States having diabetes mellitus by 2050, and every 10 th adult worldwide. Type 2 diabetes mellitus (T2DM) confers a 2- to 3-fold increased risk of cardiovascular (CV) events compared with non-diabetic patients, and CV mortality is responsible for around 80% mortality in this population. Patients with T2DM can have other features of insulin resistance-metabolic syndrome like hypertension, lipid abnormalities, and obesity which are all associated with increased CV disease and stroke risk even in the absence of T2DM. The management of a T2DM calls for employing a holistic risk factor control approach. Metformin is the first line therapy for T2DM and has been shown to have cardiovascular beneficial effects. Intense debate regarding the risk of myocardial infarction with rosiglitazone led to regulatory agencies necessitating cardiovascular outcome trials with upcoming anti-diabetic medications. Glucagon like peptide-1 agonists and sodium glucose co-transporter-2 inhibitors have shown promising CV safety and additional CV benefit in recent clinical trials. These drugs have favorable effects on traditional CV risk factors. The findings from these studies further support that fact that CV risk factor control plays an important role in reducing morbidity and mortality in T2DM patients. This review article will discuss briefly the cardiovascular safety and benefits of the oral medications which are currently being used for T2DM and will then discuss in detail about the newer medications being investigated for the treatment of T2DM.

    2009-12-01

    Full Text Available This paper summarizes the results of the PAPEETE study (Population-based Analysis of PErsistence with treatment and Economics of TElmisartan that assessed trends in prescriptions, determinants and timing of treatment discontinuation and/or changes in antihypertensive drug therapy in a cohort of hypertensive patients living in Pavia. In the study were included all new users 18 years old or over receiving a first prescription for diuretics, beta-blockers, calcium channel-blockers, ACE inhibitors (ACEi or angiotensin receptor blockers (ARBs between 1 January 2003 and 31 December 2006. The follow-up period for each patient was 12 months starting from enrolment date. Based in the presence of continuous therapy, patients were defined as persistent and non-persistent users. A total of 61,493 patients was included in the study of whom 11.2% were persistent. Persistence with the treatment seems to be associated with patient-related factors and with the class of anti-hypertensive drug initially prescribed with the lowest persistence to antihypertensive treatment with diuretics (3.0% and the highest with ARBs (18.8%.

    Caring for teens with special health care needs places physical and mental health burdens on parents, which can be exacerbated by the stresses of transitions to independence. Medical homes can improve teen transitions to greater self-management and reduce health care-related time and financial burdens for families. We examined the association between parent-reported teen medical home status and caregiver health-related quality of life (HRQOL). The study sample included parents or caregivers of teens with special health care needs aged 15 to 18 recruited from a pediatric Medicaid accountable care organization who participated in a survey (response rate, 40.5%). The primary outcome was parent HRQOL scores (0-100 points) measured using the Pediatric Quality of Life Inventory Family Impact Module. Medical home status was based on parent report of teen's health care meeting medical home criteria. Linear regression models were used to estimate HRQOL scores, adjusted for demographic characteristics, health literacy, and teen functional limitation. Among 488 parents, 27% reported their teen received care consistent with a medical home. Adjusted parent HRQOL scores were significantly higher among those whose teens had a medical home (74.40; 95% confidence interval, 71.31-77.48), relative to those whose teens did not (65.78; 95% confidence interval, 63.92-67.65). Medical home subscale analyses showed HRQOL scores had significant positive associations with family-centered care and coordinated care, but not other subscales. Teen medical home status was positively associated with caregiver HRQOL, suggesting that the medical home may benefit overall caregiver well-being. In particular, receiving care that was family centered and coordinated appeared to be the most beneficial. Copyright © 2018 Academic Pediatric Association. Published by Elsevier Inc.

    Full Text Available Jutta Dierkes, Claus Luley, Sabine WestphalInstitute of Clinical Chemistry and Biochemistry, University Hospital Magdeburg, Germany Abstract: Elevated plasma concentrations of homocysteine, a sulfur-containing amino acid, are a risk factor for coronary, cerebral and peripheral artery disease. Next to other factors, drugs used for the prevention or treatment of cardiovascular disease may modulate plasma homocysteine levels. Thus, a drug induced homocysteine increase may counteract the desired cardioprotective effect. The aim is to summarize the current knowledge on the effect of two important classes of drugs, lipid-lowering drugs and anti-hypertensive drugs, on homocysteine metabolism. Among the lipid-lowering drugs, especially the fibric acid derivatives, which are used for treatment of hypertriglyceridemia and low HDL-cholesterol, are associated with an increase of homocysteine by 20%–50%. This increase can be reduced, but not totally avoided by the addition of folic acid, vitamin B12 and B6 to fibrates. HMG-CoA reductase inhibitors (statins do not influence homocysteine concentrations substantially. The effects of nicotinic acid and n3-fatty acids on the homocysteine concentrations are less clear, more studies are necessary to clarify their influence on homocysteine. Antihypertensive drugs have also been studied with respect to homocysteine metabolism. A homocysteine increase has been shown after treatment with hydrochlorothiazide, a lowering was observed after treatment with ß-blockers, but no effect with ACE-inhibitors. The clinical significance of the homocysteine elevation by fibrates and thiazides is not clear. However, individual patients use these drugs for long time, indicating that even moderate increases may be important.Keywords: homocysteine, fibrates, diuretics, cardiovascular disease

    Prior work suggests that some but not all antihypertensive treatments may benefit cognition and risk for Alzheimer's disease, independent of stroke. Angiotensin II receptor blockers (ARBs) have been highlighted as one antihypertensive drug class that may confer greatest benefit. The participants comprised 1626 nondemented adults, aged 55-91 years, recruited from Alzheimer's Disease Neuroimaging Initiative sites. Three groups were compared: ARB users (HTN-ARBs), other antihypertensive drug users (HTN-Other), and normotensives. In post hoc analyses, we also examined (1) users of ARBs and angiotensin-converting enzyme inhibitors (ACEIs), (2) users of blood-brain barrier (BBB)-crossing ARBs and users of non-BBB-crossing ARBs, and (3) users of BBB-crossing ARBs and ACEIs (BBB crossers) and users of non-BBB-crossing ARBs and ACEIs (BBB noncrossers). Groups were compared regarding cognition and magnetic resonance imaging measures of brain volume and white matter hyperintensities (WMH), using analysis of covariance and multilevel models. At baseline, the HTN-Other group performed worse than normotensives on Rey Auditory Verbal Learning Test (RAVLT) Immediate Recall (p = 0.002), Delayed Recall (p Memory (p = 0.001), and Trails A (p Memory (p = 0.04) and worse than normotensives on Trails A (p = 0.04). The HTN-Other group performed worse than normotensives on Logical Memory Immediate (p = 0.02) and Delayed Recall over the 3-year follow-up (p = 0.007). Over the follow-up period, those taking BBB-crossing ARBs performed better than the HTN-Other group on AVLT Delayed Recall (p = 0.04), Logical Memory Immediate (p = 0.02), and Delayed Recall (p = 0.05). They also had fewer WMH than the HTN-Other group (p = 0.008) and those taking non-BBB-crossing ARBs (p = 0.05). There were no group differences in brain volume. Users of BBB-crossing medications (ARBs or ACEIs) showed better performance on AVLT Delayed Recall over time than all

  2. Effect of antihypertensive therapy on aortic distensibility in patients with hypertension. Comparison with nicardipine and trichlormethiazide

    To evaluate the aortic wall distensibility (AD) in patients with hypertension, AD was measured using cine magnetic resonance imaging in 37 hypertensive patients (HT) and 40 normal control subjects (NC). In addition, to evaluate the effect of antihypertensive drugs on AD, AD was measured before and after following antihypertensive treatments in 23 HT. Thirteen HT and 10 HT were treated for 12 weeks by 80 mg per day of nicardipine (group N) and 2-4 mg per day of trichlormethiazide (group T), respectively. Cine magnetic resonance imaging was performed at ascending (ASC) and descending (DESC) aortic levels. Aortic area was measured at the maximum and minimum frames. AD was calculated from the following formula: (Max. area - Min. area)/(Min. area x pulse pressure). AD was lower in HT than in NC both at ASC (p<0.01) and DESC (p<0.01). There was negative correlationship between age and AD in both HT and NC. After treatment of N and T, AD in all patients increased significantly. AD in ASC changed from 1.38{+-}0.99 to 5.29{+-}2.78 in HT treated by N, from 1.15{+-}0.70 to 2.48{+-}1.08 in HT treated by T, respectively. AD in DESC changed from 1.56{+-}0.87 to 5.53{+-}2.57 in HT treated by N, from 1.28{+-}0.59 to 2.67{+-}0.75 in HT treated by T, respectively. There were no significant differences in ADs of both ASC and DESC before treatment between HT treated by N and T. However, there were significant differences in ADs of both ASC and DESC after treatment between HT treated by N and T. There were no significant differences in systolic, diastolic and pulse pressures both before and after treatment between group N and group T. In conclusion, it is suspected that hypertension is the strong factor which promotes the aortic sclerosis. In addition, antihypertensive drugs have a beneficial effect on aortic distensibility, and its effect of nicardipine is stronger than that of trichlormethiazide. (author) 57 refs.

    2008-01-01

    With the international reform in medical management systems gaining ground worldwide, hospital management has gradually begun to shift its focus from providing expensive medical treatment to improving medical service quality and patient safety. In this study, we discuss the application of Radio Frequency Identification (RFID) and data integrating technology with the medical service, and examine whether or not this technology can enhance medical safety. We also discuss the possible benefits following the application of the RFID system. The findings show that the application of RFID to hospitals can actually generate benefits, which can be further divided into operational structure benefits, users' structure benefits, and organisational and environmental benefits. However, not all these benefits can achieve medical safety. Among them, only the operator and environmental benefits can play such roles. Nevertheless, the application of RFID can bring hospitals towards the integration of technology benefits and improved medical safety.

    The aim of this study was to evaluate and compare antioxidative and antihypertensive activities of Longissimus dorsi muscle from Suino Nero Lucano (SNL) and a modern crossbred (CG) pigs, before and after cooking and in vitro gastrointestinal digestion. Pig meat showed antioxidative and antihypertensive activities, heat treatment decreased the thiols content but at the same time increased angiotensin I-converting enzyme (ACE) inhibitory activity, and in vitro gastrointestinal digestion enhanced the biological activity of meat. Autochthonous SNL meat showed a higher nutraceutical quality compared to CG meat, highlighting a greater potential beneficial physiological effect on human health. The results of this study indicate that the pig meat, in particular autochthonous pig meat, may be considered a functional food since it is a good source of antioxidative and antihypertensive peptides.

    We propose statistical definitions of the individual benefit of a medical or behavioral treatment and of the severity of a chronic illness. These definitions are used to develop a graphical method that can be used by statisticians and clinicians in the data analysis of clinical trials from the perspective of personalized medicine. The method focuses on assessing and comparing individual effects of treatments rather than average effects and can be used with continuous and discrete responses, including dichotomous and count responses. The method is based on new developments in generalized linear mixed-effects models, which are introduced in this article. To illustrate, analyses of data from the Sequenced Treatment Alternatives to Relieve Depression clinical trial of sequences of treatments for depression and data from a clinical trial of respiratory treatments are presented. The estimation of individual benefits is also explained. Copyright © 2016 John Wiley & Sons, Ltd. Copyright © 2016 John Wiley & Sons, Ltd.

    The leaves of Kalanchoe pinnata (Crassulaceae) are used in Cameroon folk medicine to manage many diseases such as cardiovascular dysfunctions. In this work, we aimed to evaluate the activities of aqueous leaf extract of Kalanchoe pinnata on the blood pressure of normotensive rat (NTR) and salt hypertensive rats (SHR), as well as its antioxidant properties. Hypertension was induced in rats by oral administration of 18% NaCl for 4 weeks. For the preventive study, three groups of rats received 18% NaCl solution and the plant extract at 25 mg/kg/day, 50 mg/kg/day or 100 mg/kg/day by gavage. Two positive control groups received 18% NaCl solution and either spironolactone (0.71 mg/kg/day) or eupressyl (0.86 mg/kg/day) by gavage for 4 weeks. At the end of this experimental period, systolic arterial pressure (SAP), diastolic arterial pressure (DAP) and heart rate (HR) were measured by the invasive method. Some oxidative stress biomarkers (reduced glutathione (GSH), superoxide dismutase (SOD), nitric monoxide (NO) were evaluated in heart, aorta, liver and kidney. NO level was indirectly evaluated by measuring nitrite concentration. Kalanchoe pinnata extract prevented significantly the increase of systolic and diastolic arterial pressures in high salt-loaded rats (SHR). In SHR, concomitant administration of Kalanchoe pinnata at 25, 50 and 100 mg/kg/day significantly prevented the increase in blood pressure by 32%, 24% and 47% (for SAP); 35%, 33% and 56% (for DAP), respectively. No significant change was recorded in heart rate of those rats. The plant extract improved antioxidant status in various organs, but more potently in aorta. Thus, antioxidant and modulatory effects of Kalanchoe pinnata at the vasculature might be of preponderant contribution to its overall antihypertensive activity. The work demonstrated that the concomitant administration of high-salt and the aqueous extract of Kalanchoe pinnata elicits prevention of salt-induced hypertension in rat. This

    Increasing use is being made of routinely collected electronic patient data in health services research. The aim of the present study was to evaluate the potential usefulness of a comprehensive database used routinely in the public healthcare system in Hong Kong, using antihypertensive drug prescriptions in primary care as an example. Data on antihypertensive drug prescriptions were retrieved from the electronic Clinical Management System (e-CMS) of all primary care clinics run by the Health Authority (HA) in the New Territory East (NTE) cluster of Hong Kong between January 2004 and June 2007. Information was also retrieved on patients' demographic and socioeconomic characteristics, visit type (new or follow-up), and relevant diseases (International Classification of Primary Care, ICPC codes). 1,096,282 visit episodes were accessed, representing 93,450 patients. Patients' demographic and socio-economic details were recorded in all cases. Prescription details for anti-hypertensive drugs were missing in only 18 patients (0.02%). However, ICPC-code was missing for 36,409 patients (39%). Significant independent predictors of whether disease codes were applied included patient age > or = 70 years (OR 2.18), female gender (OR 1.20), district of residence (range of ORs in more rural districts; 0.32-0.41), type of clinic (OR in Family Medicine Specialist Clinics; 1.45) and type of visit (OR follow-up visit; 2.39). In the 57,041 patients with an ICPC-code, uncomplicated hypertension (ICPC K86) was recorded in 45,859 patients (82.1%). The characteristics of these patients were very similar to those of the non-coded group, suggesting that most non-coded patients on antihypertensive drugs are likely to have uncomplicated hypertension. The e-CMS database of the HA in Hong Kong varies in quality in terms of recorded information. Potential future health services research using demographic and prescription information is highly feasible but for disease-specific research dependant

    The present study deals with the application of mechanochemical approach for the preparation of drug-drug multicomponent solid forms of three poorly soluble antihypertensive drugs (telmisartan, irbesartan and hydrochlorothiazide) using atenolol as a coformer. The resultant solid forms comprise of cocrystal (telmisartan-atenolol), coamorphous (irbesartan-atenolol) and eutectic (hydrochlorothiazide-atenolol). The study emphasizes that solid-state transformation of drug molecules into new forms is a result of the change in structural patterns, diminishing of dimers and creating new facile hydrogen bonding network based on structural resemblance. The propensity for heteromeric or homomeric interaction between two different drugs resulted into diverse solid forms (cocrystal/coamorphous/eutectics) and become one of the interesting aspects of this research work. Evaluation of these solid forms revealed an increase in solubility and dissolution leading to better antihypertensive activity in deoxycorticosterone acetate (DOCA) salt-induced animal model. Thus, development of these drug-drug multicomponent solid forms is a promising and viable approach to addressing the issue of poor solubility and could be of considerable interest in dual drug therapy for the treatment of hypertension.

    Objective:To investigate the vasorelaxant effect of organic extracts from Apium graveolens (A. graveolens) which is a part of a group of plants subjected to pharmacological and phytochemical study with the purpose of offering it as an ideal source for obtaining lead compounds for designing new therapeutic agents with potential vasorelaxant and antihypertensive effects. Methods:An ex vivo method was employed to assess the vasorelaxant activity. This consisted of using rat aortic rings with and without endothelium precontracted with norepinephrine. Results:All extracts caused concentration-dependent relaxation in precontracted aortic rings with and without endothelium;the most active extracts were Dichloromethane and Ethyl Acetate extracts from A. graveolens. These results suggested that secondary metabolites responsible for the vasorelaxant activity belong to a group of compounds of medium polarity. Also, our evidence showed that effect induced by dichloromethane and ethyl acetate extracts from A. graveolens is mediated probably by calcium antagonism. Conclusions: A. graveolens represents an ideal source for obtaining lead compounds for designing new therapeutic agents with potential vasorelaxant and antihypertensive effects.

    Pain in adolescence is associated with mental health problems, the main reason for work disability in young adults. This study explores the relationship between multisite musculoskeletal pain in adolescence and later medical (sickness and medical rehabilitation benefits) and social welfare benefits, adjusted for sociodemographic, adolescent psychosocial and mental health problems. Data were obtained by linkage between the National Insurance Registry (2003-11) and the Norwegian Arctic Adolescent Health Study, a school-based survey in North Norway (2003-05), accepted by 3987 fifteen- to sixteen-year-olds (68% of the total population). The start of the follow-up time was July 1st of the corresponding year the participants responded to the health study. Musculoskeletal pain was measured by the number of musculoskeletal pain sites. We found a positive linear relationship between adolescent musculoskeletal pain sites and the occurrence of medical and social welfare benefits in young adulthood (p ≤ 0.001). Adolescent musculoskeletal pain was a significant predictor of sickness (p adolescent psychosocial and mental health problems. The most important adolescent psychosocial predictors were externalizing problems, less parental involvement and adverse life events. Adolescent multisite musculoskeletal pain was found to be an important predictor of later sickness and social welfare benefit receipt from adolescence to young adulthood. Adolescents with multisite musculoskeletal pain are at substantially increased risk of health and social difficulties into young adulthood. Identification and interventions for these adolescent problems could alleviate this risk and be a sound socioeconomic investment. © 2017 European Pain Federation - EFIC®.

    A major employer implemented a change to its employee health benefits program to allow beneficiaries with diabetes or high cholesterol to obtain preselected generic antidiabetic or generic antihyperlipidemic medications with a zero dollar copayment. To receive this benefit, plan beneficiaries were required to participate in a contracted vendor's case management and/or wellness program.  To assess changes in medication adherence and the costs for generic antidiabetic and generic antihyperlipidemic medications resulting from participation in a zero copay (ZCP) program.   This was a retrospective pre-post comparison group study, evaluating adherence and cost. Participants using an antihyperlipidemic and/or antidiabetic medication during the study identification period and post-implementation period for the program were considered eligible for the study. Eligible beneficiaries who enrolled in the ZCP program during the post-implementation period were considered participants, while those who did not enroll during this period were considered nonparticipants. ZCP program participants and nonparticipants were matched via a 1-to-1 propensity scoring method using age, gender, comorbidity count, medication type (antihyperlipidemic, antidiabetic, or both), and baseline adherence as matching criteria. The proportion of days covered (PDC) metric expressed as a mean percentage was used to assess adherence to medication therapy, while payer cost was examined using prescription drug utilization expressed as per member per year (PMPY) and cost change per 30 days of medication expressed in dollars.   Among participants who were users of antidiabetic medications, the mean adherence rate was sustained from pre- to post-implementation (81.8% vs. 81.9%); however, it decreased in the matched nonparticipant group (81.9% vs. 73.1%). This difference in mean adherence over time between the participants and nonparticipants was statistically significant (0.1% vs. -8.8%, P  less than  0

    The musculoskeletal physical examination (MSK PE) is an essential part of medical student training, and it is best taught in a hands-on, longitudinal fashion. A barrier to this approach is faculty instructor availability. "Near-peer" teaching refers to physicians-in-training teaching their junior colleagues. It is unknown whether near-peer teaching is effective in teaching this important physical examination skill. To investigate attitudes of medical students and physical medicine and rehabilitation (PM&R) residents regarding near-peer teaching in an MSK PE curriculum. Qualitative, anonymous paper and online surveys. Tertiary academic center with a medical school and PM&R training program. Ninety-nine second- and third-year medical students and 13 PM&R residents in their third or fourth postgraduate year. Attitudes of second- and third-year medical students were measured immediately after their MSK PE course. Resident attitudes were measured in a single cross-sectional sample. Student attitudes were assessed via a questionnaire with 5-point Likert scales and a free-text comment section. The resident questionnaire included a combination of multiple-choice questions, rankings, free-text responses, and Likert scales. All 99 students completed the questionnaire. The majority of students (n = 79 [80%]) reported that resident involvement as hands-on instructors of examination skills was "very useful," and 87 (88%) indicated that resident-led small discussion groups were "very helpful" or "somewhat helpful." Fifty-seven of 99 students (58%) reported that the resident-facilitated course was "much better" than courses without resident involvement. Twelve of 13 eligible residents completed the survey, and of those, 8 found teaching "very helpful" to their MSK knowledge, and 11 became "somewhat" or "much more confident" in clinical examination skills. Our study supports educational benefits to medical students and resident instructors in our MSK PE program. We recommend

    Full Text Available Our previous studies have shown that Uncaria has an important role in lowering blood pressure, but its intervention mechanism has not been clarified completely in the metabolic level. Therefore, in this study, a combination method of HPLC-TOF/MS-based metabolomics and multivariate statistical analyses was employed to explore the mechanism and evaluate the antihypertensive effect of Uncaria. Serum samples were analyzed and identified by HPLC-TOF/MS, while the acquired data was further processed by partial least squares discriminant analysis (PLS-DA and orthogonal partial least squares discriminant analysis (OPLS-DA to discover the perturbed metabolites. A clear cluster among the different groups was obtained, and 7 significantly changed potential biomarkers were screened out. These biomarkers were mainly associated with lipid metabolism (dihydroceramide, ceramide, PC, LysoPC, and TXA2 and vitamin and amino acids metabolism (nicotinamide riboside, 5-HTP. The result indicated that Uncaria could decrease the blood pressure effectively, partially by regulating the above biomarkers and metabolic pathways. Analyzing and verifying the specific biomarkers, further understanding of the therapeutic mechanism and antihypertensive effect of Uncaria was acquired. Metabolomics provided a new insight into estimate of the therapeutic effect and dissection of the potential mechanisms of traditional Chinese medicine (TCM in treating hypertension.

    Basing on the data of ultrasound study we compared effects of various antihypertensive therapies on elastic properties of common carotid arteries and the thoracic aorta in 133 patients aged 65-80 years with nonvalvular atrial fibrillation (AF). The use of perindopril, lercanidipin, valsartan and its combination with rosuvastatin was associated with elevation of the distensibility index of common carotid artery and lowering of coefficient of stiffness of aortic wall compared with the initial state. Combination of valsartan (80-160 mg/day) with rosuvastatin 10 (mg/day) produced most pronounced effect on compliance of vascular wall compared with other variants of treatment. Combination of valsartan and rosuvastatin can be considered an optimal strategy of antihypertensive therapy allowing to improve elastic properties of arterial wall in elderly patients with nonvalvular AF.

    To examine the issues surrounding the development and implementation of a behind-the-counter (BTC) category of medications. Testimony from organizations submitting comments to the Food and Drug Administration (FDA) panel hearings in November 2007, the 2009 final report of the U. S. General Accounting Office regarding a BTC drug category, literature review of research that has been conducted, experiences from other countries, and publically available information from agencies in charge of regulating medications similar to BTC. Based on evidence attained from the current work, the following six recommendations regarding a BTC category of medications are provided. (1) Demonstration needs to occur that the risks and/or costs of BTC are outweighed by benefits, positive measurable outcomes, and financial savings to society. (2) Sufficient resources, including personnel, equipment, and facilities, need to be available for the appropriate provision of BTC services and to ensure ongoing monitoring and controls. (3) An appropriate compensation structure needs to be developed. (4) Encounters and outcomes should be documented in an electronic record, the information should be shared with other health care providers involved in patients' care, and interprofessional collaboration and communication should occur. (5) Criteria for designating candidates for transition, ongoing review for safety, and reverse transition must be developed. (6) Applicable lessons learned from other countries should be incorporated into BTC strategies. In addition to implementation recommendations, we also summarize additional evidence that needs to be gathered to optimize the BTC model. Based on the accumulated evidence, comments to FDA's request, and information from other countries, implementation of a BTC model probably is feasible in the United States. However, the optimal model remains uncertain and various aspects of a program need to be prioritized and rigorously tested.

    In recent years, across the United States, many school districts have cut on-site delivery of health services by eliminating or reducing services provided by qualified school nurses. Providing cost-benefit information will help policy makers and decision makers better understand the value of school nursing services. To conduct a case study of the Massachusetts Essential School Health Services (ESHS) program to demonstrate the cost-benefit of school health services delivered by full-time registered nurses. Standard cost-benefit analysis methods were used to estimate the costs and benefits of the ESHS program compared with a scenario involving no school nursing service. Data from the ESHS program report and other published studies were used. A total of 477 163 students in 933 Massachusetts ESHS schools in 78 school districts received school health services during the 2009-2010 school year. School health services provided by full-time registered nurses. Costs of nurse staffing and medical supplies incurred by 78 ESHS districts during the 2009-2010 school year were measured as program costs. Program benefits were measured as savings in medical procedure costs, teachers' productivity loss costs associated with addressing student health issues, and parents' productivity loss costs associated with student early dismissal and medication administration. Net benefits and benefit-cost ratio were calculated. All costs and benefits were in 2009 US dollars. During the 2009-2010 school year, at a cost of $79.0 million, the ESHS program prevented an estimated $20.0 million in medical care costs, $28.1 million in parents' productivity loss, and $129.1 million in teachers' productivity loss. As a result, the program generated a net benefit of $98.2 million to society. For every dollar invested in the program, society would gain $2.20. Eighty-nine percent of simulation trials resulted in a net benefit. The results of this study demonstrated that school nursing services provided in

     Patients' access to their computerised medical records (CMRs) is a legal right in many countries. However, little is reported about the benefit-risk associated with patients' online access to their CMRs.  To conduct a consensus exercise to assess the impact of patients' online access to their CMRs on the quality of care as defined in six domains by the Institute of Medicine (IoM), now the National Academy of Medicine (NAM).  A five-round Delphi study was conducted. Round One explored experts' (n = 37) viewpoints on providing patients with access to their CMRs. Round Two rated the appropriateness of statements arising from Round One (n = 16). The third round was an online panel discussion of findings (n = 13) with the members of both the International Medical Informatics Association and the European Federation of Medical Informatics Primary Health Care Informatics Working Groups. Two additional rounds, a survey of the revised consensus statements and an online workshop, were carried out to further refine consensus statements.  Thirty-seven responses from Round One were used as a basis to initially develop 15 statements which were categorised using IoM's domains of care quality. The experts agreed that providing patients online access to their CMRs for bookings, results, and prescriptions increased efficiency and improved the quality of medical records. Experts also anticipated that patients would proactively use their online access to share data with different health care providers, including emergencies. However, experts differed on whether access to limited or summary data was more useful to patients than accessing their complete records. They thought online access would change recording practice, but they were unclear about the benefit-risk of high and onerous levels of security. The 5-round process, finally, produced 16 consensus statements.  Patients' online access to their CMRs should be part of all CMR systems. It improves the process

  10. Emergency Medical Technician Training During Medical School: Benefits for the Hidden Curriculum.

    2017-07-01

    Medical schools are encouraged to introduce students to clinical experiences early, to integrate biomedical and clinical sciences, and to expose students to interprofessional health providers and teams. One important goal is for students to gain a better understanding of the patients they will care for in the future and how their social and behavioral characteristics may affect care delivery. To promote early clinical exposure and biomedical integration, in 2012 the University of South Carolina School of Medicine Greenville incorporated emergency medical technician (EMT) training into the curriculum. This report describes the program; outlines changes (made after year 1) to improve biomedical integration; and provides a brief analysis and categorization of comments from student reflections to determine whether particular themes, especially related to the hidden curriculum, appeared. Medical students wrote frequently about EMT-related experiences: 29% of reflections in the charter year (1.2 per student) and 38% of reflections in the second year (1.5 per student) focused on EMT-related experiences. Reflections related to patient care, professionalism, systems-based practice, and communication/interpersonal skills. The frequency of themes in student reflections may provide insight into a medical program's hidden curriculum. This information may serve to inform curricula that focus on biosocial elements such as professionalism and communication with the goal of enhancing future physicians' tolerance, empathy, and patient-centeredness. The authors plan to conduct further qualitative analysis of student reflections to iteratively revise curricula to address gaps both in learning and in the differences between the explicit curriculum and actual experiences.

    Few studies have focused on school activities of children who are medically fragile/technology-dependent. This article reports on an exploratory, interpretive study that examined the perceptions of parents, nurses, and educators with regard to their school concerns and strategies for ensuring the safety and health of these students. Informants all believed that attending school provided benefits to most children who are medically fragile/technology-dependent, including opportunities for skill acquisition, socialization, and respite care for families. However, they also perceived that there were real risks involved, including obtaining appropriate care, exposure to infection, and social isolation or teasing. Copyright 2002, Elsevier Science (USA).

    High blood pressure is a global health concern which is mainly managed by taking anti-hypertensive medications. Although medication is available to control high blood pressure, adhering to treatment is a major problem among hypertensive patients. The purpose of the study was to assess the predisposing, enabling and reinforcing factors to medication adherence among hypertensive patients in Gweru urban aged 40-70 years. A descriptive cross sectional study was used with a sample size of 110 conveniently sampled hypertensive patients. We used an interviewer administered questionnaire designed using phase 4 of the PRECEDE model. The modal age was 70 years and mean age was 58 years (SD=10.29). There were 61.8% females and 38.2% males. Variables associated with medication adherence were: age (P=0.0059), marital status (P=0.015), average monthly income (P=0.0002), support group (P=0.027) and knowledge (P=0.0058). Providing information to patients with high blood pressure and having a good patient-provider relationship improves medication adherence. There is need to focus on the predisposing, enabling and reinforcing factors of medication adherence since demographic and socio-economic factors may be more difficult to change.

    Currently, medical cannabis polices are experiencing rapid changes, and an increasing number of nations around the world legalize medical cannabis for certain groups of patients, including those in Serbia. To determine medical students' attitudes toward medical cannabis legalization and to examine the factors influencing their attitudes. Fourth-year medical students at the Faculty of Medicine, University of Belgrade, had participated in a cross-sectional study. Data were collected by an anonymous questionnaire. Overall, 63.4% students supported medical cannabis legalization, and only 20.8% supported its legalization for recreational use. Students who previously used marijuana (p medical cannabis legalization compared with students who never used them. Support for marijuana recreational use was also related to prior marijuana (p cancer (90.4%) and chronic pain (74.2%) were correctly reported approved medical indications by more than half the students. Students who supported medical cannabis legalization showed better knowledge about indications, in contrast to opponents for legalization who showed better knowledge about side effects. Beliefs that using medical cannabis is safe and has health benefits were correlated with support for legalization, and previous marijuana and alcohol use, while beliefs that medical cannabis poses health risks correlated most strongly with previous marijuana use. Conclusions/Importance: The medical students' attitudes toward medical cannabis legalization were significantly correlated with previous use of marijuana and alcohol, knowledge about medical indications and side effects, and their beliefs regarding medical cannabis health benefits and risks.

    The influence of dietary composition on blood pressure is an important subject in healthcare. Interactions between antihypertensive drugs and diet (IBADD) is the most important factor in the management of hypertension. It is therefore essential to support healthcare providers' decision making role in active and continuous interaction control in hypertension management. The aim of this study was to implement an ontology-based clinical decision support system (CDSS) for IBADD management (IBADDM). We considered the concepts of antihypertensive drugs and foods, and focused on the interchangeability between the database and the CDSS when providing tailored information. An ontology-based CDSS for IBADDM was implemented in eight phases: (1) determining the domain and scope of ontology, (2) reviewing existing ontology, (3) extracting and defining the concepts, (4) assigning relationships between concepts, (5) creating a conceptual map with CmapTools, (6) selecting upper ontology, (7) formally representing the ontology with Protégé (ver.4.3), (8) implementing an ontology-based CDSS as a JAVA prototype application. We extracted 5,926 concepts, 15 properties, and formally represented them using Protégé. An ontology-based CDSS for IBADDM was implemented and the evaluation score was 4.60 out of 5. We endeavored to map functions of a CDSS and implement an ontology-based CDSS for IBADDM.

    Full Text Available Background: Medication reconciliation is a major component of safe patient care. One of the main problems in the implementation of a medication reconciliation process is the lack of human resources. With limited resources, it is better to target medication reconciliation resources to patients who will derive the most benefit from it. Objective: The primary objective of this study was to determine the frequency and types of medication reconciliation errors identified by pharmacists performing medication reconciliation at admission. Each medication error was rated for its potential to cause patient harm during hospitalization. A secondary objective was to determine risk factors associated with medication reconciliation errors. Methods: This was a prospective, single-center pilot study conducted in the internal medicine and surgical wards of a tertiary care teaching hospital in the Eastern province of Saudi Arabia. A clinical pharmacist took the best possible medication history of patients admitted to medical and surgical services and compared with the medication orders at hospital admission; any identified discrepancies were noted and analyzed for reconciliation errors. Multivariate logistic regression was performed to determine the risk factors related to reconciliation errors. Results: A total of 328 patients (138 in surgical and 198 in medical were included in the study. For the 1419 medications recorded, 1091 discrepancies were discovered out of which 491 (41.6% were reconciliation errors. The errors affected 177 patients (54%. The incidence of reconciliation errors in the medical patient group was 25.1% and 32.0% in the surgical group (p<0.001. In both groups, the most frequent reconciliation error was the omission (43.5% and 51.2%. Lipid-lowering (12.4% and antihypertensive agents were most commonly involved. If undetected, 43.6% of order errors were rated as potentially requiring increased monitoring or intervention to preclude harm; 17

    systematic data on the impact that longitudinal clinical trials have on patient participants are needed to ensure that all the risks and potential benefits of participating in clinical research are properly evaluated and disclosed. Recognizing the lack of systematic data on this topic, we surveyed 582 individuals from Argentina, Brazil, and Thailand who were participating in the ESPRIT study, a Phase III randomized trial of interleukin-2 in HIV disease. Respondents were asked about the benefits and burdens of participating in ESPRIT using a self-administered survey. We found that 91% of respondents in the IL-2 treatment arm and 79% in the no IL-2 control arm reported medical benefits from their participation. In addition, 68% in the IL-2 treatment arm and 60% of the no IL-2 controls reported non-medical benefits. Thirteen percent of the IL-2 respondents and 5% of the non-IL2 respondents reported problems with their jobs due to study participation. Given that respondents, including those in the control arm, reported medical and non-medical benefits and burdens from their research participation, investigators and review committees should be aware of and respond to the potential for research participants to experience benefits and burdens that are unrelated to the intervention being tested.

    Learning Management Systems (LMS) are a feasible solution to fulfill the various requirements for e-learning based training in a medical university. Using the LMS ILIAS, the Institute of Diagnostic and Interventional Radiology has designed an e-learning unit about data protection, which has been used by 73% of the department's employees in the first three months. To increase the use of e-learning for staff training, it is necessary to identify barriers and benefits, which encourage the use of e-learning. Therefore, we started an online survey to examine how the employees evaluate this learning opportunity. The results show that 87% of the employees had no technical problems and also competence of Information and Communication Technology (ICT) was no barrier. If anything, reported issues were time shortages and tight schedules. Therefore, short learning modules (less than 20 minutes) are preferred. Furthermore, temporal flexibility for learning is important for 83% of employees.

    This study aimed to determine which methods of expressing a preventive medication's benefit encourage patients with known cardiovascular disease to decide to take the medication and which methods patients prefer. We identified patients in Auckland, New Zealand, family practices located in areas of differing socioeconomic status who had preexisting heart disease (myocardial infarction, angina, or both) and were taking statins. The patients were interviewed about their preference for methods of expressing the benefit of a hypothetical medication. Benefits were expressed numerically (relative risk, absolute risk, number needed to treat, odds ratio, natural frequency) and graphically. Statistical testing was adjusted for practice. We interviewed 100 eligible patients, representing a 53% response rate. No matter how the risk was expressed, the majority of patients indicated they would be encouraged to take the medication. Two-thirds (68) of the patients preferred 1 method of expressing benefit over others. Of this group, 57% preferred the information presented graphically. This value was significantly greater (P framing preferred positive framing (description of the benefit of treatment) over negative framing (description of the harm of not being treated). Although number needed to treat is a useful tool for communicating risk and benefit to clinicians, this format was the least likely to encourage patients to take medication. As graphical representation of benefit was the method patients preferred most, consideration should be given to developing visual aids to support shared clinical decision making.

    Angiotensin-converting enzyme inhibitors are treatment of choice in hypertensive patients. Clinically used inhibitors exhibit a structural similarity to naturally occurring peptides. This study evaluated antihypertensive and cardioprotective effects of ACE-inhibiting peptides derived from food proteins in spontaneously hypertensive rats. Isoleucine-tryptophan (in vitro IC50 for ACE = 0.7 μm), a whey protein hydrolysate containing an augmented fraction of isoleucine-tryptophan, or captopril was given to spontaneously hypertensive rats (n = 60) over 14 weeks. Two further groups, receiving either no supplement (Placebo) or intact whey protein, served as controls. Systolic blood pressure age-dependently increased in the Placebo group, whereas the blood pressure rise was effectively blunted by isoleucine-tryptophan, whey protein hydrolysate and captopril (-42 ± 3, -38 ± 5, -55 ± 4 mm Hg vs. Placebo). At study end, myocardial mass was lower in isoleucine-tryptophan and captopril groups but only partially in the hydrolysate group. Coronary flow reserve (1 μm adenosine) was improved in isoleucine-tryptophan and captopril groups. Plasma ACE activity was significantly decreased in isoleucine-tryptophan, hydrolysate and captopril groups, but in aortic tissue only after isoleucine-tryptophan or captopril treatment. This was associated with lowered expression and activity of matrix metalloproteinase-2. Following isoleucine-tryptophan and captopril treatments, gene expression of renin was significantly increased indicating an active feedback within renin-angiotensin system. Whey protein hydrolysate and isoleucine-tryptophan powerfully inhibit plasma ACE resulting in antihypertensive effects. Moreover, isoleucine-tryptophan blunts tissue ACE activity, reduces matrix metalloproteinase-2 activity and improves coronary flow reserve. Thus, whey protein hydrolysate and particularly isoleucine-tryptophan may serve as innovative food additives with the goal of attenuating

    Marijuana has been used medically since antiquity. In recent years there has been a resurgence of interest in medical applications of various cannabis preparations. These drugs have been cited in the medical literature as potential secondary treatment agents for severe pain, muscle spasticity, anorexia, nausea, sleep disturbances, and numerous other uses. This article reviews the research literature related to medical applications of various forms of cannabis. Benefits related to medical use of cannabinoids are examined and a number of potential risks associated with cannabis use, both medical and recreational, are considered. There is a clearly identified need for further research to isolate significant benefits from the medical application of cannabinoids and to establish dosage levels, appropriate delivery mechanisms and formulations, and to determine what role, if any, cannabinoids might play in legitimate medical applications. It is also imperative to determine if reported dangers pose a significant health risks to users.

    This exploratory study analyzed the content of medical tourism Web sites in an attempt to examine how they convey information about benefits and risks of medical procedures, how they frame credibility, and the degree to which these Web sites include interactive features for consumers. Drawing upon framing theory, the researchers content analyzed a sample of 66 medical tourism Web sites throughout the world. The results indicated that medical tourism Web sites largely promote the benefits of medical procedures while downplaying the risks, and relatively little information regarding the credibility of these services appears. In addition, the presentation of benefits/risks, credibility, and Web site interactivity were found to differ by region and type of facility. The authors discuss the implications of these findings concerning the framing of medical tourism Web site content, future directions for research, and limitations.

Two similar open, randomized, cross-over studies (morning vs evening intake were carried out. Duration of the initial wash-out period was 2 weeks; duration of both treatment courses — 3 weeks; the interval between courses — 1 week. Only patients with stable HT (mean day-time BP>135/85 mm Hg were included. Ambulatory BP monitoring (ABPM was carried out prior to treatment and at the end of both treatment courses. The patients performed home BP monitoring (HBPM throughout the study. Pharmacokinetics of verapamil (n=14, mean daily dose — 240.0±16.3 mg was studied to assess compliance with verapamil therapy. In ramipril trial (n=30 its mean daily dose was 8.9±0.7 mg. The following main ABPM variables were analyzed: ABPM means and variability, maximal and minimal values, nocturnal BP fall, parameters of Fourier transformation and smoothness index. The morning and evening BP means and morning BP surge (morning – evening BP were assessed by HBPM. Student’s t-value and Mahalanobis distance were used to evaluate individual value of each variable (“morning” vs “evening” effect. This analysis was first done separately for each trial. After that, combined data were analyzed. Results. Overall antihypertensive effect was more intense with morning ramipril (p<0.05 intake and evening verapamil intake. The t-values ranged 2.2-2.3 for nocturnal BP fall; 2.0-2.1 for night-time BP variability; 3.8-4.3 for morning BP surge. The t-values of office and 24-hour BP were low (0.2-1.7. Conclusion. Morning BP surge based on HBPM is a good instrument for chronotherapy effect assessment. Evening administration of antihypertensive drugs causes nocturnal BP fall shift towards “dipper” status.

    Since 2003 and 2005, National Pilot Medical Financial Assistance Scheme (MFA) has been implemented in rural and urban areas of China to improve the poorest families' accessibility to health services. Local governments of the pilot areas formulated various benefit packages. Comparative evaluation research on the effect of different benefit packages is urgently needed to provide evidence for improving policy-making of MFA. This study was based on a MFA pilot project, which was one component of Health VIII Project conducted in rural China. This article aimed to compare difference in health services utilization of poor families between two benefit package project areas: H8 towns (package covering inpatient service, some designated preventive and curative health services but without out-patient service reimbursement in Health VIII Project,) and H8SP towns (package extending coverage of target population, covering out- patient services and reducing co-payment rate in Health VIII Supportive Project), and to find out major influencing factors on their services utilization. A cross-sectional survey was conducted in 2004, which used stratified cluster sampling method to select poor families who have been enrolled in MFA scheme in rural areas of ChongQing. All family members of the enrolled households were interviewed. 748 and 1129 respondents from two kinds of project towns participated in the survey. Among them, 625 and 869 respondents were included (age>/=15) in the analysis of this study. Two-level linear multilevel model and binomial regressions with a log link were used to assess influencing factors on different response variables measuring service utilization. In general, there was no statistical significance in physician visits and hospitalizations among all the respondents between the two kinds of benefit package towns. After adjusting for major confounding factors, poor families in H8SP towns had much higher frequency of MFA use (beta = 1.17) and less use of

Three hundred and fifty one cancer patients were recruited from the Affiliated Jiangyin Hospital of Southeast University Medical College and the Nantong Tumor Hospital. One-way ANOVA, Pearson Chi-square tests and regression analysis were employed to identify the correlations between physical exercise and the measured factors. The results showed that occupation type (χ2 = 14.065; p = 0.029), monthly individual monthly income level (χ2 = 24.795; p = 0.003), BMI (χ2 = 15.709; p = 0.015) and diagnosis (χ2 = 42.442; p exercise with different frequency per week. Differences in the frequency of exercise were associated with different degrees of reported Benefit Finding (BF) (F = 24.651; p exercise. Our results indicated that benefit finding, medical coping modes, communication with doctors, social support, depression and quality of life were significantly correlated with exercise. The variance in several psychosocial factors (benefit finding, medical coping modes, the communication with doctors, depression and quality of life) could be explained by exercise. Psychosocial factors should be addressed and examined over time when evaluating the effect of physical exercise that is prescribed as a clinically relevant treatment.

    The longitudinal integrated clerkship is a model of clinical education driven by tenets of social cognitive theory, situated learning, and workplace learning theories, and built on a foundation of continuity between students, patients, clinicians, and a system of care. Principles and goals of this type of clerkship are aligned with primary care principles, including patient-centered care and systems-based practice. Academic medical centers can partner with community health systems around a longitudinal integrated clerkship to provide mutual benefits for both organizations, creating a sustainable model of clinical training that addresses medical education and community health needs. A successful one-year longitudinal integrated clerkship was created in partnership between an academic medical center and an integrated community health system. Compared with traditional clerkship students, students in this clerkship had better scores on Clinical Performance Examinations, internal medicine examinations, and high perceptions of direct observation of clinical skills.Advantages for the academic medical center include mitigating the resources required to run a longitudinal integrated clerkship while providing primary care training and addressing core competencies such as systems-based practice, practice-based learning, and interprofessional care. Advantages for the community health system include faculty development, academic appointments, professional satisfaction, and recruitment.Success factors include continued support and investment from both organizations' leadership, high-quality faculty development, incentives for community-based physician educators, and emphasis on the mutually beneficial relationship for both organizations. Development of a longitudinal integrated clerkship in a community health system can serve as a model for developing and expanding these clerkship options for academic medical centers.

Effective chromatographic separation was achieved on Fluka TLC plates 20 × 20 cm aluminum cards, 0.2 mm thickness through linear ascending development. For Mixture I, the mobile phase composed of chloroform–methanol in the ratio 8:2 v/v. Detection was performed at 254 nm for both carvedilol and hydrochlorothiazide. For Mixture II, the mobile phase was chloroform–methanol–ammonia in the volume ratio 8:2:0.1. Detection was performed at 254 nm for valsartan and hydrochlorothiazide, and at 365 nm for amlodipine. Quantification was based on spectrodensitometric analysis. Analytical performance of the proposed HPTLC procedures was statistically validated with respect to linearity, ranges, precision, accuracy, specificity, robustness, detection and quantification limits. The linearity ranges were 0.05–1.0 and 0.1–2.0 μg/spot for carvedilol and hydrochlorothiazide, respectively in Mixture I, 0.1–2.0, 0.1–2.0 and 0.2–4.0 μg/spot for amlodipine, hydrochlorothiazide and valsartan, respectively in Mixture II, with correlation coefficients >0.9992. The validated HPTLC methods were applied to the analysis of the cited antihypertensive drugs in their combined pharmaceutical tablets. The proposed methods confirmed peak identity and purity.

    The 2017 American College of Cardiology/American Heart Association (ACC/AHA) Guideline for the Prevention, Detection, Evaluation and Management of High Blood Pressure in Adults provides recommendations for the definition of hypertension, systolic and diastolic blood pressure (BP) thresholds for initiation of antihypertensive medication, and BP target goals. This study sought to determine the prevalence of hypertension, implications of recommendations for antihypertensive medication, and prevalence of BP above the treatment goal among U.S. adults using criteria from the 2017 ACC/AHA guideline and the Seventh Report of the Joint National Committee on Prevention, Detection, Evaluation, and Treatment of High Blood Pressure (JNC7). The authors analyzed data from the 2011 to 2014 National Health and Nutrition Examination Survey (N = 9,623). BP was measured 3 times following a standardized protocol and averaged. Results were weighted to produce U.S. population estimates. According to the 2017 ACC/AHA and JNC7 guidelines, the crude prevalence of hypertension among U.S. adults was 45.6% (95% confidence interval [CI]: 43.6% to 47.6%) and 31.9% (95% CI: 30.1% to 33.7%), respectively, and antihypertensive medication was recommended for 36.2% (95% CI: 34.2% to 38.2%) and 34.3% (95% CI: 32.5% to 36.2%) of U.S. adults, respectively. Nonpharmacological intervention is advised for the 9.4% of U.S. adults with hypertension who are not recommended for antihypertensive medication according to the 2017 ACC/AHA guideline. Among U.S. adults taking antihypertensive medication, 53.4% (95% CI: 49.9% to 56.8%) and 39.0% (95% CI: 36.4% to 41.6%) had BP above the treatment goal according to the 2017 ACC/AHA and JNC7 guidelines, respectively. Compared with the JNC7 guideline, the 2017 ACC/AHA guideline results in a substantial increase in the prevalence of hypertension, a small increase in the percentage of U.S. adults recommended for antihypertensive medication, and more intensive BP

According to the 2017 ACC/AHA and JNC7 guidelines, the crude prevalence of hypertension among US adults was 45.6% (95% confidence interval [CI]: 43.6% to 47.6%) and 31.9% (95% CI: 30.1% to 33.7%), respectively, and antihypertensive medication was recommended for 36.2% (95% CI: 34.2% to 38.2%) and 34.3% (95% CI: 32.5% to 36.2%) of US adults, respectively. Nonpharmacological intervention is advised for the 9.4% of US adults with hypertension who are not recommended for antihypertensive medication according to the 2017 ACC/AHA guideline. Among US adults taking antihypertensive medication, 53.4% (95% CI: 49.9% to 56.8%) and 39.0% (95% CI: 36.4% to 41.6%) had BP above the treatment goal according to the 2017 ACC/AHA and JNC7 guidelines, respectively. Compared with the JNC7 guideline, the 2017 ACC/AHA guideline results in a substantial increase in the prevalence of hypertension, a small increase in the percentage of US adults recommended for antihypertensive medication, and more intensive BP lowering for many

Previous research identifying factors influencing adherence has focused primarily on broad, population-based approaches. Identifying specific barriers for an individual is more useful in designing meaningful targeted interventions. Using customized telephonic outreach, we examined specific patient-reported barriers influencing hypertensive patients' nonadherence to medication in order to identify targeted interventions.Methods: A telephone survey of 8692 nonadherent hypertensive patients was conducted. The patient sample comprised health plan members with at least two prescriptions for antihypertensive medications in 2008. The telephone script was based on the "target" drug associated with greatest nonadherence (medication possession ratio [MPR] <80% during the four-month period preceding the survey.Results: The response rate was 28.2% of the total sample, representing 63.8% of commercial members and 37.2% of Medicare members. Mean age was 63.4 years. Mean MPR was 61.0% for the target drug. Only 58.2% of Medicare respondents and 60.4% of commercial respondents reported "missing a dose of medication". The primary reason given was "forgetfulness" (61.8% Medicare, 60.8% commercial, followed by "being too busy" (2.7% Medicare, 18.5% commercial and "other reasons" (21.9% Medicare, 8.1% commercial including travel, hospitalization/sickness, disruption of daily events

    Context Little information exists concerning the frequency of clinically significant incidental findings (IFs) identified in the course of imaging research across a broad spectrum of imaging modalities and body regions. Objective To estimate the frequency with which research imaging IFs generate further clinical action, and the medical benefit/burden of identifying these IFs. Design, Setting, and Participants Retrospective review of subjects undergoing a research imaging exam that was interpreted by a radiologist for IFs in the first quarter of 2004, with 3-year clinical follow-up. An expert panel reviewed IFs generating clinical action to determine medical benefit/burden based on predefined criteria. Main Outcome Measures Frequency of (1) IFs that generated further clinical action by modality, body part, age, gender, and (2) IFs resulting in clear medical benefit or burden. Results 1376 patients underwent 1426 research imaging studies. 40% (567/1426) of exams had at least one IF (1055 total). Risk of an IF increased significantly by age (OR=1.5; [1.4–1.7=95% C.I.] per decade increase). Abdominopelvic CT generated more IFs than other exams (OR=18.9 compared with ultrasound; 9.2% with subsequent clinical action), with CT Thorax and MR brain next (OR=11.9 and 5.9; 2.8% and 2.2% with action, respectively). Overall 6.2% of exams (35/567) with an IF generated clinical action, resulting in clear medical benefit in 1.1% (6/567) and clear medical burden in 0.5% (3/567). In most instances, medical benefit/burden was unclear (4.6%; 26/567). Conclusions The frequency of IFs in imaging research exams varies significantly by imaging modality, body region and age. Research imaging studies at high risk for generating IFs can be identified. Routine evaluation of research images by radiologists may result in identification of IFs in a substantial number of cases and subsequent clinical action to address them in much smaller number. Such clinical action can result in medical

    The treatment of arterial hypertension (AH) in patients with metabolic syndrome (MS) is a challenge, since non drug therapies are difficult to implement and optimal pharmacological treatment is not fully established. To assess the blockade of the rennin angiotensin aldosterone system (RAAS) in blood pressure (BP) in renal function and morphology in an experimental model of MS induced by high fat diet. Wistar rats were fed on high fat diet from the fourth week of life, for 20 weeks. The groups received Losartan or Spironolactone from the eighth week of life. We weekly evaluated the body weight and BP by tail plethysmography. At the end of the experiment oral glucose tolerance, lipid profile, creatinine clearance tests, and the direct measurement of BP were performed. A morphometric kidney analysis was performed. The administration of high-fat diet was associated with the development of MS, characterized by central fat accumulation, hypertension, hyperglycemia and hypertriglyceridemia. In this model there were no changes in renal histomorphometry. The blockade of angiotensin II (Ang II) receptor AT1 prevented the development of hypertension. The mineralocorticoid blockage did not have antihypertensive efficacy but was associated with reduction of abdominal fat. The dissociation of the antihypertensive response to the blockades of Ang II receptors and mineralocorticoid indicates the involvement of Ang II in the pathogenesis of hypertension associated with obesity. Reduction of central obesity with Spironolactone suggests the presence of mineralocorticoid adipogenic effect.

    This study aimed to optimise the experimental conditions of extraction of the phytochemical compounds and functional properties of Centaurea cyanus petals. The following parameters were determined: the chemical composition (LC-ESI-MS/MS), the effects of pH on the stability and antioxidant activity of anthocyanins, the inhibition of lipid peroxidation, antioxidant activity, anti-hemolytic activity, antimicrobial, anti-hypertensive, and cytotoxic/cytoprotective effect, and the measurements of intracellular reactive oxygen species. Results showed that the temperature and time influenced (p ≤ 0.05) the content of flavonoids, anthocyanins, and FRAP. Only the temperature influenced the total phenolic content, non-anthocyanin flavonoids, and antioxidant activity (DPPH). The statistical approach made it possible to obtain the optimised experimental extraction conditions to increase the level of bioactive compounds. Chlorogenic, caffeic, ferulic, and p-coumaric acids, isoquercitrin, and coumarin were identified as the major compounds in the optimised extract. The optimised extract presented anti-hemolytic and anti-hypertensive activity in vitro, in addition to showing stability and reversibility of anthocyanins and antioxidant activity with pH variation. The C. cyanus extract exhibited high IC 50 and GI 50 (>900 μg/mL) values for all cell lines, meaning low cytotoxicity. Based on the stress oxidative assay, the extract exhibited pro-oxidant action (10-100 μg/mL) but did not cause damage or cell death. Copyright © 2018. Published by Elsevier Ltd.

    Full Text Available Background Despite common usage of traditional medicines in rural populations, the data of their uses along with hypertension medications are limited. Aims To quantify the use of traditional medicines and to identify factors associated with its use among people with hypertension in a low-resource setting. Methods Data were collected using a researcher-administered questionnaire from people with hypertension in rural underdeveloped villages in Indonesia. Results Two hundred sixty-three of 384 participants (68.5 per cent used traditional medicines intended to lower blood pressure; about half (n=134 used only traditional medicines, whereas the others (n=129 also took antihypertensive medications. Seventy-four (19.2 per cent participants took only anti-hypertensive medications, and 47 (12.2 per cent did not use traditional medicines or antihypertensive medications. Herbal medicines were the most frequent products used, mainly in the form of herbs and herbal materials, which were obtained from traditional markets (n=169, 44 per cent, family members (n=100, 26 per cent or their own garden (n=88, 23 per cent. The use of traditional medicines was not associated with any sociodemographic variables. However, among traditional medicines users, participants with a lower formal educational level were twice as likely to not take antihypertensive medications compared with those with a higher educational level. Conclusion To treat their hypertension, these rural villagers used traditional medicines more often than anti-hypertensive medications. Health professionals in rural areas should be aware of how the use of traditional medicine might affect hypertension management.

    Full Text Available Oral administration is the most convenient route among various routes of drug delivery as it offers high patient compliance. However, the poor aqueous solubility and poor enzymatic/metabolic stability of drugs are major limitations in successful oral drug delivery. There are several approaches to improve problems related to hydrophobic drugs. Among various approaches, nanotechnology based drug delivery system has potential to overcome the challenges associated with the oral route of administration. Novel drug delivery systems are available in many areas of medicine. The application of these systems in the treatment of hypertension continues to broaden. The present review focuses on various nanocarriers available in oral drug administration for improving solubility profile, dissolution, and consequently bioavailability of hydrophobic antihypertensive drugs.

    Full Text Available Abstract Background A randomised trial of a multifaceted intervention for improving adherence to clinical practice guidelines for the pharmacological management of hypertension and hypercholesterolemia increased prescribing of thiazides, butdetected no impact onthe use of cardiovascular risk assessment toolsor achievement of treatment targets. We carried out a predominantly quantitative process evaluation to help explain and interpret the trial-findings. Methods Several data-sources were used including: questionnaires completed by pharmacists immediately after educational outreach visits, semi-structured interviews with physicians subjected to the intervention, and data extracted from their electronic medical records. Multivariate regression analyses were conducted to explore the association between possible explanatory variables and the observed variation across practices for the three main outcomes. Results The attendance rate during the educational sessions in each practice was high; few problems were reported, and the physicians were perceived as being largely supportive of the recommendations we promoted, except for some scepticism regarding the use of thiazides as first-line antihypertensive medication. Multivariate regression models could explain only a small part of the observed variation across practices and across trial-outcomes, and key factors that might explain the observed variation in adherence to the recommendations across practices were not identified. Conclusion This study did not provide compelling explanations for the trial results. Possible reasons for this include a lack of statistical power and failure to include potential explanatory variables in our analyses, particularly organisational factors. More use of qualitative research methods in the course of the trial could have improved our understanding.

    Although generic and earlier brand-name counterparts are bioequivalent, their equivalence in preventing relevant clinical outcomes is of concern. To compare effectiveness of generic and brand-name antihypertensive drugs for preventing the onset of cardiovascular (CV) outcomes. A population-based, nested case-control study was carried out by including the cohort of 78 520 patients from Lombardy (Italy) aged 18 years or older who were newly treated with antihypertensive drugs during 2005. Cases were the 2206 patients who experienced a hospitalization for CV disease from initial prescription until 2011. One control for each case was randomly selected from the same cohort that generated cases. Logistic regression was used to model the CV risk associated with starting on and/or continuing with generic or brand-name agents. There was no evidence that patients who started on generics experienced different CV risk than those on brand-name product (OR 0·86; 95% CI 0·63-1·17). Patients at whom generics were main dispensed had not significantly difference in CV outcomes than those mainly on brand-name agents (OR 1·19; 95% CI 0·86-1·63). Compared with patients who kept initial brand-name therapy, those who experienced brand-to-generic or generic-to-brand switches, and those always on generics, did not show differential CV risks, being the corresponding ORs (and 95% CIs), 1·18 (0·96-1·47), 0·87 (0·63-1·21) and 1·08 (0·80-1·46). Our findings do not support the notion that brand-name antihypertensive agents are superior to generics for preventing CV outcomes in the real-world clinical practice. © 2014 Stichting European Society for Clinical Investigation Journal Foundation.

    Herbal cannabis has been used for thousands of years for medical purposes. With elucidation of the chemical structures of tetrahydrocannabinol (THC) and cannabidiol (CBD) and with discovery of the human endocannabinoid system, the medical usefulness of cannabinoids has been more intensively explored. While more randomized clinical trials are needed for some medical conditions, other medical disorders, like chronic cancer and neuropathic pain and certain symptoms of multiple sclerosis, have substantial evidence supporting cannabinoid efficacy. While herbal cannabis has not met rigorous FDA standards for medical approval, specific well-characterized cannabinoids have met those standards. Where medical cannabis is legal, patients typically see a physician who "certifies" that a benefit may result. Physicians must consider important patient selection criteria such as failure of standard medical treatment for a debilitating medical disorder. Medical cannabis patients must be informed about potential adverse effects, such as acute impairment of memory, coordination and judgment, and possible chronic effects, such as cannabis use disorder, cognitive impairment, and chronic bronchitis. In addition, social dysfunction may result at work/school, and there is increased possibility of motor vehicle accidents. Novel ways to manipulate the endocannbinoid system are being explored to maximize benefits of cannabinoid therapy and lessen possible harmful effects.

    A dysfunctional BBB is a common feature in a variety of brain disorders, a fact stressing the need for diagnostic tools designed to assess brain vessels' permeability in space and time. Biological research has benefited over the years various means to analyze BBB integrity. The use of biomarkers for improper BBB functionality is abundant. Systemic administration of BBB impermeable tracers can both visualize brain regions characterized by BBB impairment, as well as lead to its quantification. Additionally, locating molecular, physiological content in regions from which it is restricted under normal BBB functionality undoubtedly indicates brain pathology-related BBB disruption. However, in-depth research into the BBB's phenotype demands higher analytical complexity than functional vs. pathological BBB; criteria which biomarker based BBB permeability analyses do not meet. The involvement of accurate and engineering sciences in recent brain research, has led to improvements in the field, in the form of more accurate, sensitive imaging-based methods. Improvements in the spatiotemporal resolution of many imaging modalities and in image processing techniques, make up for the inadequacies of biomarker based analyses. In pre-clinical research, imaging approaches involving invasive procedures, enable microscopic evaluation of BBB integrity, and benefit high levels of sensitivity and accuracy. However, invasive techniques may alter normal physiological function, thus generating a modality-based impact on vessel's permeability, which needs to be corrected for. Non-invasive approaches do not affect proper functionality of the inspected system, but lack in spatiotemporal resolution. Nevertheless, the benefit of medical imaging, even in pre-clinical phases, outweighs its disadvantages. The innovations in pre-clinical imaging and the development of novel processing techniques, have led to their implementation in clinical use as well. Specialized analyses of vessels' permeability

    Kerner, Daniel E; Knezevich, Emily L

    The primary objective of this study was to determine if an online reminder decreased the rate of primary nonadherence for antihypertensive medications in patients seen in 2 primary care clinics in Omaha, NE. The secondary objectives were to determine if patients receiving the intervention achieved lower blood pressure values at follow-up visits and to determine if the intervention decreased the number of days between prescribing and prescription pick-up. A report was generated in an electronic health record to identify patients prescribed a new antihypertensive medication from a physician at one of the primary care clinics. Patients that failed to pick up this new prescription from the pharmacy within 7 days were sent an electronic reminder via an online patient portal. A baseline comparator group was created with the use of retrospective chart reviews for the 6 months before prospective data collection. Primary nonadherence rate and blood pressure values at follow-up visits were compared between the prospective and baseline comparator groups. The primary nonadherence rate decreased from 65.5% to 22.2% when comparing the baseline and prospective groups, respectively. The mean days to prescription pick-up decreased from 24.5 to 12.56 in the baseline and prospective groups. The prospective group showed a larger decrease in systolic blood pressure (17.33 mm Hg vs. 0.75 mm Hg) and diastolic blood pressure (6.56 mm Hg vs. 2.25 mm Hg) compared with the baseline group. An online reminder through the electronic medical record appears to improve patient primary nonadherence, number of days between prescribing and prescription pick-up, and blood pressure measurements at follow-up visits. This research shows that an online reminder may be a valuable tool to improve patient primary adherence and health outcomes. Further research is needed with the use of a larger sample population to support any hypotheses about the effectiveness of the intervention. Copyright © 2017 American

    Refractory hypertension is an extreme phenotype of treatment failure defined as uncontrolled blood pressure (BP) in spite of ≥5 classes of antihypertensive agents, including chlorthalidone and a mineralocorticoid receptor antagonist. A prospective evaluation of possible mechanisms of refractory hypertension has not been done. The goal of this study was to test for evidence of heightened sympathetic tone as indicated by 24-hr urinary (U-) normetanephrine levels, clinic and ambulatory heart rate (HR), HR variability (HRV), arterial stiffness as indexed by pulse wave velocity (PWV), and systemic vascular resistance (SVR) compared to patients with controlled resistant hypertension. Forty-four consecutive patients, 15 with refractory and 29 with controlled resistant hypertension, were evaluated prospectively. Refractory hypertensive patients were younger (48±13.3 vs. 56.5±14.1 years, p=0.038) and more likely female (80.0 vs 51.9 %, p=0.047) compared to patients with controlled resistant hypertension. They also had higher U-normetanephrine levels (464.4±250.2 vs. 309.8±147.6 μg/24h, p=0.03), higher clinic HR (77.8±7.7 vs. 68.8±7.6 bpm, p=0.001) and 24-hr ambulatory HR (77.8±7.7 vs 68.8±7.6, p=0.0018), higher PWV (11.8±2.2 vs. 9.4±1.5 m/s, p=0.009), reduced HRV (4.48 vs. 6.11, p=0.03), and higher SVR (3795±1753 vs. 2382±349 dyne·sec·cm5·m2, p=0.008). These findings are consistent with heightened sympathetic tone being a major contributor to antihypertensive treatment failure and highlight the need for effective sympatholytic therapies in patients with refractory hypertension.

    Recent studies demonstrated that the antihypertensive drug Valsartan improved spatial and episodic memory in mouse models of Alzheimer’s Disease (AD) and human subjects with hypertension. However, the molecular mechanism by which Valsartan can regulate cognitive function is still unknown. Here, we investigated the effect of Valsartan on dendritic spine formation in primary hippocampal neurons, which is correlated with learning and memory. Interestingly, we found that Valsartan promotes spinogenesis in developing and mature neurons. In addition, we found that Valsartan increases the puncta number of PSD-95 and trends toward an increase in the puncta number of synaptophysin. Moreover, Valsartan increased the cell surface levels of AMPA receptors and selectively altered the levels of spinogenesis-related proteins, including CaMKIIα and phospho-CDK5. These data suggest that Valsartan may promote spinogenesis by enhancing AMPA receptor trafficking and synaptic plasticity signaling. PMID:24012668

    To improve individual health quality measures, which are associated with varying degrees of health benefit, and composite quality metrics, which weight individual measures identically. We developed a health-weighted composite quality measure reflecting the total health benefit conferred by a health plan annually, using preventive care as a test case. Using national disease prevalence, we simulated a hypothetical insurance panel of individuals aged 25 to 84 years. For each individual, we estimated the gain in life expectancy associated with 1 year of health system exposure to encourage adherence to major preventive care guidelines, controlling for patient characteristics (age, race, gender, comorbidity) and variation in individual adherence rates. This personalized gain in life expectancy was used to proxy for the amount of health benefit conferred by a health plan annually to its members, and formed weights in our health-weighted composite quality measure. We aggregated health benefits across the health insurance membership panel to analyze total health system performance. Our composite quality metric gave the highest weights to health plans that succeeded in implementing tobacco cessation and weight loss. One year of compliance with these goals was associated with 2 to 10 times as much health benefit as compliance with easier-to-follow preventive care services, such as mammography, aspirin, and antihypertensives. For example, for women aged 55 to 64 years, successful interventions to encourage weight loss were associated with 2.1 times the health benefit of blood pressure reduction and 3.9 times the health benefit of increasing adherence with screening mammography. A single health-weighted quality metric may inform measurement of total health system performance.

    Although many clinical studies suggest the medical utility of marijuana for some conditions, the scientific evidence is weak. Many patients in California are self-medicating with marijuana, and physicians need data to assess the risks and benefits. The only reasonable solution to this problem is to encourage research on the medical effects of marijuana. The current regulatory system should be modified to remove barriers to clinical research with marijuana. The NIH panel has identified several...

    Little is known about the impact of treatment-resistant hypertension (TRH) on health-related quality of life (HrQoL). We aimed to compare HrQoL measures in adults with apparent TRH (aTRH) and non-resistant hypertension among nationally representative US Medical Expenditure Panel Survey data pooled from 2000 to 2011. Cohorts compared were adults with aTRH (⩾2 unique fills from ⩾4 antihypertensive classes during a year) versus non-resistant hypertension (those with hypertension not meeting the aTRH definition). Key outcomes were cohort differences in SF-12v2 physical component summary (PCS) and mental component summary (MCS) scores and disease-state utility using the SF-6D. Of 57 150 adults with hypertension, 2501 (4.4%) met criteria for aTRH. Persons with aTRH, compared with non-resistant hypertension, were older (mean, 68 vs 61 years), had a higher BMI (30.9 vs 29.7 kg m(-)(2)) and were more likely to be Black (20% vs 14%), but less likely to be female (46% vs 54%). Persons with aTRH, compared with non-resistant hypertension, had lower mean PCS scores (35.8 vs 43.2; Phypertension. In conclusion, aTRH was associated with substantially lower HrQoL in physical functioning and health utility, but not in mental functioning, compared with non-resistant hypertension. The multivariable-adjusted reduction in physical functioning was similar in magnitude to previous observations comparing hypertension with no hypertension.

    Many studies have reported the negative effects of depression on adherence to antihypertensive medication. However, little is known about the mechanism underlying this relationship in elderly patients with hypertension. The aim of this cross-sectional study is to examine the mediating role of self-efficacy in the relationship between depression and medication adherence among older patients with hypertension. The data were collected from October to December 2014. A total of 255 older patients with hypertension were assessed using the Geriatric Depression Scale, the Self-efficacy for Appropriate Medication Use Scale, and the Morisky Medication Adherence Scale. Hierarchical linear regression analysis and the Sobel test were used to examine the mediating role of self-efficacy in the relationship between depression and medication adherence. Depression and self-efficacy were statistically significant predictors of medication adherence in older patients with hypertension. Self-efficacy partially mediated the relationship between depression and medication adherence. Interventions targeting self-efficacy could increase the confidence of patients in their ability to actively take their medicines. Moreover, health care providers should be aware of the importance of early detection of depression in older patients with hypertension. Future studies with longitudinal data are warranted to clarify the multidirectional relationships between depression, self-efficacy, and medication adherence. © 2017 John Wiley & Sons Australia, Ltd.

  1. Cannabis and neuropsychiatry, 1: benefits and risks.

    Science.gov (United States)

    Andrade, Chittaranjan

    2016-05-01

    Cannabis is popularly believed to be a relatively benign substance. Cannabis is also considered to have potential medical benefits, and medical marijuana has been legislated in many parts of the world. However, a recent meta-analysis found that cannabinoids were associated with only modest benefits for chemotherapy-related nausea and vomiting, small and inconsistent benefits for pain and spasticity, and inconclusive benefits for other indications such as improvement of appetite and weight, reduction in tic severity, and improvement of mood or sleep. On the flip side, cannabinoids and cannabis have acute and long-term adverse effects. In randomized controlled trials, cannabinoids increase the risk of total adverse events, serious adverse events, and dropout due to adverse events. Cannabis impairs cognition, and driving after cannabis use is associated with an increased risk of traffic accidents, including fatal accidents. Long-term cannabis use may lead to dependence, respiratory conditions, psychosis, and possibly cancer, as well. Cannabis use during pregnancy may compromise certain pregnancy outcomes such as fetal growth, and use during adolescence may compromise neurodevelopment, social adjustment, and vocational success. The composition and bioavailability of cannabis vary across preparations of the substance and routes of administration; this limits the ability to generalize the findings of studies. The findings of older research may no longer apply to current strains of cannabis that are higher in psychotogenic content. It is important for medical professionals and the lay public to understand the limitations of the efficacy data and the seriousness of the risks associated with cannabis use in medical and recreational contexts. © Copyright 2016 Physicians Postgraduate Press, Inc.

    Epidemiological studies have shown an increasing prevalence of obesity and the metabolic syndrome worldwide. Lifestyle modifications that include dietary changes, weight reduction, and exercise are the cornerstones in the treatment of this pathology. However, adherence to this approach often meets with failure in clinical practice; therefore, drug therapy should not be delayed. The ideal pharmacological antihypertensive regimen should target the underlying mechanisms involved in this syndrome, including sympathetic activation, increased renal tubular sodium reabsorption, and overexpression of the renin-angiotensin-aldosterone system by the adipocyte. Few prospective trials have been conducted in the search of the ideal antihypertensive regimen in patients with obesity and the metabolic syndrome. We summarize previously published ad hoc studies, prospective studies, and guideline publications regarding the treatment of hypertension in patients with obesity and the metabolic syndrome. We conclude that the optimal antihypertensive drug therapy in these patients has not been defined. Though caution exists regarding the use of thiazide diuretics due to potential metabolic derangements, there is insufficient data to show worsened cardiovascular or renal outcomes in patients treated with these drugs. In regard to beta blockers, the risk of accelerating conversion to diabetes and worsening of inflammatory mediators described in patients treated with traditional beta blockers appears much less pronounced or absent when using the vasodilating beta blockers. Renin-angiotensin-aldosterone system (RAAS) inhibition with an ACE or an ARB and treatment with calcium channel blockers appears safe and well tolerated in obesity-related hypertension and in patients with metabolic syndrome. Future prospective pharmacological studies in this population are needed.

Prescription surveys permit the identification of suboptimal prescribing patterns for further evaluation. The aims of this study were to determine the prescribing trend, adherence of the prescribers to the guideline, and the impact of drug expenditure on drug utilization at the cardiac clinic of Penang Hospital, Malaysia. This was a cross-sectional study. Demographic data of the patients, diagnoses and the drugs prescribed were recorded. The average drug acquisition costs (ADAC were calculated for each antihypertensive drug class on a daily and annual basis. Adherence to the guideline was calculated as a percentage of the total number of patients. A total of 313 individuals fulfilled the inclusion criteria. The average age of the study population was 59.30 ± 10.35 years. The mean number of drugs per prescription in the study was 2.09 ± 0.78. There were no significant differences in the demographic data. Antihypertensive drugs were used in monotherapy and polytherapy in 20.8% and 79.2% of the patients, respectively. Adherence to the guideline regarding prescription occurred in 85.30% of the patients. The lowest priced drug class was diuretics and the highest was angiotensin-receptor blockers. In conclusion, the total adherence to the guideline was good; the adherence percentage only slightly decreased with a co-existing comorbidity (such as diabetes mellitus. The use of thiazide diuretics was encouraged because they are well tolerated and

    In Germany, educational deficits or potential benefits involved in global health education have not been analysed till now. We assess the importance medical students place on learning about social determinants of health (SDH) and assess their knowledge of global health topics in relation to (i) mobility patterns, their education in (ii) tropical medicine or (iii) global health. Cross-sectional study among medical students from all 36 medical schools in Germany using a web-based, semi-structured questionnaire. Participants were recruited via mailing-lists of students' unions, all medical students registered in 2007 were eligible to participate in the study. We captured international mobility patterns, exposure to global health learning opportunities and attitudes to learning about SDH. Both an objective and subjective knowledge assessment were performed. 1126 online-replies were received and analysed. International health electives in developing countries correlated significantly with a higher importance placed on all provided SDH (p ≤ 0.006). Participation in tropical medicine (p educational system' (p = 0.007) and the 'health system structure' (p = 0.007), while the item 'politics' was marginally significant (p = 0.053).In the knowledge assessment students achieved an average score of 3.6 (SD 1.5; Mdn 4.0), 75% achieved a score of 4.0 or less (Q25 = 3.0; Q75 = 4.0) from a maximum achievable score of 8.0. A better performance was associated with international health electives (p = 0.032), participation in tropical medicine (p = 0.038) and global health (p = 0.258) courses. The importance medical students in our sample placed on learning about SDH strongly interacts with students' mobility, and participation in tropical medicine and global health courses. The knowledge assessment revealed deficits and outlined needs to further analyse education gaps in global health.

    Although voluntary medical male circumcision (VMMC) in Iganga district was launched in 2010 as part of the Uganda national strategy to prevent new HIV infections with a target of having 129,896 eligible males circumcised by 2012, only 35,000 (27%) of the anticipated target had been circumcised by mid 2012. There was paucity of information on why uptake of VMMC was low in this setting where HIV awareness is presumably high. This study sought to understand motivators for uptake of VMMC from the perspective of the clients themselves in order to advocate for feasible approaches to expanding uptake of VMMC in Iganga district and similar settings. In Iganga district, we conducted seven key informant interviews with staff who work in the VMMC clinics and twenty in-depth interviews with clients who had accepted and undergone VMMC. Ten focus-group discussions including a total of 112 participants were also conducted with clients who had undergone VMMC. Motivators for uptake of VMMC in the perspective of the circumcised clients and the health care staff included: perceived medical benefit to those circumcised such as protection against acquiring HIV and other sexually transmitted diseases, peer/partner influence, sexual satisfaction and safety and cost to access the service. Since perceived medical benefit was a motivator for seeking VMMC, it can be used to strengthen campaigns for increasing uptake of VMMC. Peer influence could also be used in advocacy campaigns for VMMC expansion, especially using peers who have already undergone VMMC. There is need to ensure that safety and cost to access the service is affordable especially to rural poor as it was mentioned as a motivator for seeking VMMC.

    Catheter-based renal denervation is a new approach to treat hypertension via modulation of the renal sympathetic nerves. Although nonrandomized and small, open-label randomized studies resulted in significant reductions in office blood pressure 6months after renal denervation with monopolar radiofrequency catheters, the first prospective, randomized, sham-controlled study (Symplicity HTN-3) failed to meet its blood pressure efficacy end point. New clinical trials with new catheters have since been designed to address the limitations of earlier studies. Accordingly, the RADIANCE-HTN and REQUIRE studies are multicenter, blinded, randomized, sham-controlled trials designed to assess the blood pressure-lowering efficacy of the ultrasound-based renal denervation system (Paradise) in patients with established hypertension either on or off antihypertensive medications, is designed to evaluate patients in 2 cohorts-SOLO and TRIO, in the United States and Europe. The SOLO cohort includes patients with essential hypertension, at low cardiovascular risk, and either controlled on 1 to 2 antihypertensive medications or uncontrolled on 0 to 2 antihypertensive medications. Patients undergo a 4-week medication washout period before randomization to renal denervation (treatment) or renal angiogram (sham). The TRIO cohort includes patients with hypertension resistant to at least 3 antihypertensive drugs including a diuretic. Patients will be stabilized on a single-pill, triple-antihypertensive-drug combination for 4weeks before randomization to treatment or sham. Reduction in daytime ambulatory systolic blood pressure (primary end point) will be assessed at 2months in both cohorts. A predefined medication escalation protocol, as needed for blood pressure control, is implemented between 2 and 6months in both cohorts by a study staff member blinded to the randomization process. At 6months, daytime ambulatory blood pressure and antihypertensive treatment score will be assessed. REQUIRE

    Screening tools exist to help identify patient issues related to social determinants of health (SDH), but solutions to many of these problems remain elusive to health care providers as they require legal solutions. Interprofessional medical-legal education is essential to optimizing health care delivery. In 2011, the authors implemented a four-session didactic interprofessional curriculum on medical-legal practice for third-year medical students at Morehouse School of Medicine. This program, also attended by law students, focused on interprofessional collaboration to address client/patient SDH issues and health-harming legal needs. In 2011-2014, the medical students participated in pre- and postintervention surveys designed to determine their awareness of SDH's impact on health as well as their attitudes toward screening for SDH issues and incorporating resources, including a legal resource, to address them. Mean ratings were compared between pre- and postintervention respondent cohorts using independent-sample t tests. Of the 222 medical students who participated in the program, 102 (46%) completed the preintervention survey and 100 (45%) completed the postintervention survey. Postintervention survey results indicated that students self-reported an increased likelihood to screen patients for SDH issues and an increased likelihood to refer patients to a legal resource (P education into undergraduate medical education may result in an increased likelihood to screen patients for SDH and to refer patients with legal needs to a legal resource. In the future, an additional evaluation to assess the curriculum's long-term impact will be administered prior to graduation.

    Little is known about how perceived social standing versus traditional socioeconomic characteristics influence medication adherence and blood pressure (BP) among African American and white patients with hypertension in the rural southeastern United States. Perceived social standing, socioeconomic characteristics, self-reported antihypertensive medication adherence, and BP were measured at baseline in a cohort of rural African American and white patients (n = 495) with uncontrolled hypertension attending primary care practices. Multivariate models examined the relationship of perceived social standing and socioeconomic indicators with medication adherence and systolic BP. Medication nonadherence was reported by 40% of patients. Younger age [β = 0.20; P = .001], African American race [β = -0.30; P = .03], and lower perceived social standing [β = 0.08; P = .002] but not sex or traditional socioeconomic characteristics including education and household income, were significantly associated with lower medication adherence. Race-specific analyses revealed that this pattern was limited to African Americans and not observed in whites. In stepwise modeling, older age [β = 0.57, P = .001], African American race [β = 4.4; P = .03], and lower medication adherence [β = -1.7, P = .01] but not gender, education, or household income, were significantly associated with higher systolic BP. Lower perceived social standing and age, but not traditional socioeconomic characteristics, were significantly associated with lower medication adherence in African Americans. Lower medication adherence was associated with higher systolic BP. These findings suggest the need for tailored, culturally relevant medication adherence interventions in rural communities. © 2015 National Rural Health Association.

    Erectile dysfunction (ED) is common among men taking antihypertensive agents to control blood pressure. We evaluated the efficacy and safety of sildenafil citrate in men with ED taking antihypertensive agents. A total of 198 male subjects, aged 20 years and older were enrolled. This study was conducted for 10 weeks as an open-label, multicenter and flexible dose trial with a 2-week screening period and an 8-week treatment phase. Subjects were asked to complete Event Log Worksheets, as well as the International Index of Erectile Function (IIEF) and the Global Efficacy Assessment Questions (GEAQ) questionnaires during the study period. The average age among the 167 subjects who completed the study was 55.8 (31.7 to 77.1). The scores for questions 3 and 4 of IIEF improved from 2.3 and 1.8 at baseline to 3.7 and 3.4 at week 4 and 3.8 and 3.4 at week 8, respectively. There were 86.3% of the patients reported improved erectile function at week 8; 88.3% of the patients reported improved ability to achieve sexual intercourse at week 8. There were no significant differences observed in the responses to questions 3 and 4 of IIEF and GEAQ by the number of antihypertensive agents taken. The adverse events were facial flushing (20.1%), headache (11.7%), palpitation (5.0%), rhinitis (2.8%), URI (2.8%), dizziness (2.2%), dyspnea (2.2%), and nausea (1.7%). Sildenafil citrate is an effective treatment for ED; it is safe and well tolerated by patients with ED taking multiple antihypertensive agents for arterial hypertension.

  15. Competency-based training: who benefits?

    Science.gov (United States)

    Brightwell, Alexandra; Grant, Janet

    2013-02-01

    Competency based training describes progression through training referenced to the demonstrated ability to perform certain tasks. In recent years, this has become the dominant curriculum model. We seek to examine who benefits from a competency based approach to medical education. For the regulators and service, the apparent advantage is in terms of apparent measurable accountability and flexibility. For assessors, the promise of competence based assessments in the workplace to provide a reliable and objective measurement of a trainee's performance has not been demonstrated in practice. For the doctor in training, there is very little evidence to show benefit from competency based training. Competency based training places emphasis on individual skills rather than overall learning experience thus risks diminishing the role of the trainee in the workplace. Any form of medical education that devalues workplace based learning will ultimately harm the profession and, in turn, patient care.

    Aim We assessed the effectiveness of fourth-line mineralocorticoid receptor antagonists in comparison with other fourth-line anti-hypertensive agents in resistant hypertension. Methods and results We systematically searched Medline, EMBASE and the Cochrane library from database inception until January 2016. We included randomised and non-randomised studies that compared mineralocorticoid receptor antagonists with other fourth-line anti-hypertensive agents in patients with resistant hypertension. The outcome was change in systolic blood pressure, measured in the office, at home or by ambulatory blood pressure monitoring. Secondary outcomes were changes in serum potassium and occurrence of hyperkalaemia. We used random effects models and assessed statistical heterogeneity using the I 2 test and corresponding 95% confidence intervals. From 2,506 records, 5 studies met our inclusion criteria with 755 included patients. Two studies were randomised and three were non-randomised. Comparative fourth-line agents included bisoprolol, doxazosin, furosemide and additional blockade of the renin angiotensin-aldosterone system. Using data from randomised studies, mineralocorticoid receptor antagonists reduced blood pressure by 7.4 mmHg (95%CI 3.2 - 11.6) more than the active comparator. When limited to non-randomised studies, mineralocorticoid receptor antagonists reduced blood pressure by 11.9 mmHg (95% CI 9.3 - 14.4) more than the active comparator. Conclusion On the basis of this meta-analysis, mineralocorticoid receptor antagonists reduce blood pressure more effectively than other fourth-line agents in resistant hypertension. Effectiveness stratified by ethnicity and comorbidities, in addition to information on clinical outcomes such as myocardial infarction and stroke, now needs to be determined.

    We reviewed the existing programs for basic medical education (BME) in Israel as well as their output, since they are in a phase of reassessment and transition. The transition has been informed, in part, by evaluation in 2014 by an International Review Committee (IRC). The review is followed by an analysis of its implications as well as the emergent roadmap for the future. The review documents a trend of modernizing, humanizing, and professionalizing Israeli medical education in general, and BME in particular, independently in each of the medical schools. Suggested improvements include an increased emphasis on interactive learner-centered rather than frontal teaching formats, clinical simulation, interprofessional training, and establishment of a national medical training forum for faculty development. In addition, collaboration should be enhanced between medical educators and health care providers, and among the medical schools themselves. The five schools admitted about 730 Israeli students in 2015, doubling admissions from 2000. In 2014, the number of new licenses, including those awarded to Israeli international medical graduates (IMGs), surpassed for the first time in more than a decade the estimated need for 1100 new physicians annually. About 60 % of the licenses awarded in 2015 were to IMGs. Israeli BME is undergoing continuous positive changes, was supplied with a roadmap for even further improvement by the IRC, and has doubled its output of graduates. The numbers of both Israeli graduates and IMGs are higher than estimated previously and may address the historically projected physician shortage. However, it is not clear whether the majority of newly licensed physicians, who were trained abroad, have benefited from similar recent improvements in medical education similar to those benefiting graduates of the Israeli medical schools, nor is it certain that they will benefit from the further improvements that have recently been recommended for the Israeli

    Exposure to commonly prescribed medications may be associated with cancer risk. However, there is limited data in kidney cancer. Furthermore, methods of classifying cumulative medication exposure in previous studies may be prone to bias. We conducted a population-based case-control study of 10,377 incident kidney cancer cases aged ≥66 years matched with 35,939 controls on age, sex, history of hypertension, comorbidity score, and geographic location. Cumulative exposure to commonly prescribed medications hypothesised to modulate cancer risk was obtained using prescription claims data. We modelled exposure in four different fashions: (1) as continuous exposures using (a) fractional polynomials (which allow for a non-linear relationship between an exposure and outcome) or (b) assuming linear relationships; and 2) as dichotomous exposures denoting (a) ≥3 years versus kidney cancer. The directions of association were relatively consistent across analyses; however, the magnitudes were sensitive to the method of analysis. When utilising fractional polynomials, increasing cumulative exposure to acetylsalicylic acid, selective serotonin reuptake inhibitors, and proton-pump inhibitors was associated with significantly reduced risk of kidney cancer, while increasing exposure to antihypertensive drugs was associated with significantly increased risk. Our study provides impetus to further explore the effect of commonly prescribed medications on carcinogenesis to identify modifiable pharmacological interventions to reduce the risk of kidney cancer.

    The snake venom proline-rich peptide BPP 10c is an active somatic angiotensin-converting enzyme (sACE) inhibitors. Recently we demonstrated that the anti-hypertensive effect of BPP 10c is not related to the inhibition of sACE alone, thus suggesting that this enzyme is not its only target for blood pressure reduction. In the present work, a biodistribution study in Swiss mice of [(125)I]-BPP 10c in the absence or in the presence of a saturating concentration of captopril, a selective active-site inhibitor of sACE, demonstrated that: (1) [(125)I]-BPP 10c was present in several organs and the renal absorption was significantly high; (2) [(125)I]-BPP 10c showed a clear preference for the kidney, maintaining a high concentration in this organ in the presence of captopril for at least 3h; (3) The residual amount of [(125)I]-BPP 10c in the kidney of animals simultaneously treated with captopril suggest that the peptide can interact with other targets different from sACE in this organ. We also showed that Cy3-labeled BPP 10c was internalized by human embryonic kidney cells (HEK-293T). Taken together, these results suggest that sACE inhibition by captopril affects the tissue distribution of [(125)I]-BPP 10c and that the anti-hypertensive effects of BPP 10c are not only dependent on sACE inhibition.

    Unhealthy lifestyle factors may contribute to apparent treatment resistant hypertension (aTRH). We examined associations of unhealthy lifestyle factors with aTRH in individuals taking antihypertensive medications from three or more classes. Participants (n = 2602) taking three or more antihypertensive medication classes were identified from the population-based REasons for Geographic And Racial Differences in Stroke (REGARDS) study. aTRH was defined as having SBP/DBP at least 140/90 mmHg despite the use of three or more antihypertensive medication classes or the use of four or more classes to achieve blood pressure control. Lifestyle factors included obesity, physical inactivity, current smoking, heavy alcohol consumption, a low Dietary Approaches to Stop Hypertension (DASH) diet score and high sodium-to-potassium (Na/K) intake. Among participants taking three or more antihypertensive medication classes, 1293 (49.7%) participants had aTRH. The prevalence of unhealthy lifestyle factors in participants with and without aTRH was 55.2 and 51.7%, respectively, for obesity, 42.2 and 40.5% for physical inactivity, 11.3 and 11.5% for current smoking, 3.1 and 4.0% for heavy alcohol consumption, 23.1 and 21.5% for low-DASH diet score, and 25.4 and 24.4% for high Na/K intake. After adjustment for age, sex, race, and geographic region of residence, none of the unhealthy lifestyle factors were associated with aTRH. The associations between each unhealthy lifestyle factor and aTRH remained nonsignificant after additional adjustment for education, income, depressive symptoms, total calorie intake, and comorbidities. Unhealthy lifestyle factors did not have independent associations with aTRH among individuals taking three or more antihypertensive medication classes.

    Background In the search of safe and effective lead molecules from natural sources, Mucuna pruriens (MP) L. (Fabaceae) seeds were utilized for exploring the antihypertensive potential. Traditionally, it is used as diuretic and hypotensive. Methods Bioassay-guided fractions were utilized for the isolation of active compounds by column chromatography. IC50 value, enzyme kinetics and inhibition mechanism were determined. In vivo time and dose-dependent hypotensive study followed by changes in mean arterial pressure (MAP) induced by angiotensin I (3 nmol/kg), angiotensin II (3 nmol/kg), and bradykinin (10 nmol/kg) in anesthetized rats was done. Plasma and tissue angiotensin I-converting enzyme (ACE) activities were also determined. Results Phytochemical analysis by spectroscopic techniques revealed the presence of known compounds like genistein, ursolic acid and L-DOPA from the ethyl acetate and water fraction, respectively. In vitro study revealed MP ethyl acetate (MPEA) fraction and genistein as the most active fraction (IC50 156.45 µg/mL) and compound (IC50 253.81 µM), respectively. Lineweaver-Burk plots revealed a non-competitive mode of inhibition. ACE protein precipitation was the suggested mechanism for inhibition. The extract showed a time- and dose-dependent decrease in MAP. Genistein was able to dose-dependently reduce the MAP, up to 53±1.5 mmHg (40 mg/kg, i.v.). As compared to control, it showed a dose-dependent decrease in plasma ACE activity of 40.61 % and 54.76 % at 10 mg/kg and 20 mg/kg, respectively. It also decreased the ACE activity in the aorta (107.67nM/ml min at 10 mg, p<0.001; 95.33nM/ml min at 20 mg p<0.001). Captopril was used as a standard for various in vitro and in vivo assays. Conclusions The study revealed the antihypertensive potential of MP seed compounds via ACE inhibition.

    Full Text Available Providing benefits and payments to participants in health research, either in cash or in kind, is a common but ethically controversial practice. While much literature has concentrated on appropriate levels of benefits or payments, this paper focuses on less well explored ethical issues around the nature of study benefits, drawing on views of community members living close to an international health research centre in Kenya.The consultation, including 90 residents purposively chosen to reflect diversity, used a two-stage deliberative process. Five half-day workshops were each followed by between two and four small group discussions, within a two week period (total 16 groups. During workshops and small groups, facilitators used participatory methods to share information, and promote reflection and debate on ethical issues around types of benefits, including cash, goods, medical and community benefits. Data from workshop and field notes, and voice recordings of small group discussions, were managed using Nvivo 10 and analysed using a Framework Analysis approach.The methods generated in-depth discussion with high levels of engagement. Particularly for the most-poor, under-compensation of time in research carries risks of serious harm. Cash payments may best support compensation of costs experienced; while highly valued, goods and medical benefits may be more appropriate as an 'appreciation' or incentive for participation. Community benefits were seen as important in supporting but not replacing individual-level benefits, and in building trust in researcher-community relations. Cash payments were seen to have higher risks of undue inducement, commercialising relationships and generating family conflicts than other benefits, particularly where payments are high. Researchers should consider and account for burdens families may experience when children are involved in research. Careful context-specific research planning and skilled and consistent

    Results of a study to characterize patterns of nonadministration of medication doses for venous thromboembolism (VTE) prevention among hospitalized patients are presented. The electronic records of all patients admitted to 4 floors of a medical center during a 1-month period were examined to identify patients whose records indicated at least 1 nonadministered dose of medication for VTE prophylaxis. Proportions of nonadministered doses by medication type, intended route of administration, and VTE risk categorization were compared; reasons for nonadministration were evaluated. Overall, 12.7% of all medication doses prescribed to patients in the study cohort ( n = 75) during the study period (857 of 6,758 doses in total) were not administered. Nonadministration of 1 or more doses of VTE prophylaxis medication was nearly twice as likely for subcutaneous anticoagulants than for all other medication types (231 of 1,112 doses [20.8%] versus 626 of 5,646 doses [11.2%], p < 0.001). For all medications prescribed, the most common reason for nonadministration was patient refusal (559 of 857 doses [65.2%]); the refusal rate was higher for subcutaneous anticoagulants than for all other medication categories (82.7% versus 58.8%, p < 0.001). Doses of antiretrovirals, immunosuppressives, antihypertensives, psychiatric medications, analgesics, and antiepileptics were less commonly missed than doses of electrolytes, vitamins, and gastrointestinal medications. Scheduled doses of subcutaneous anticoagulants for hospitalized patients were more likely to be missed than doses of all other medication types.
