    Full Text Available OBJECTIVE: To evaluate the frequency of oral antihypertensive medication preceding the increase in blood pressure in patients in a university hospital, the drug of choice, and the maintained use of antihypertensive medication. METHODS: Data from January to June 1997 from the University Hospital Professor Edgard Santos Pharmacy concerning the prescriptions of all inpatients were used. Variables included in the analysis were: antihypertensive medication prescription preceding increase in blood pressure, type of antihypertensive medication, gender, clinical or surgical wards, and the presence of maintained antihypertensive medication. RESULTS: The hospital admitted 2,532 patients, 1,468 in surgical wards and 818 in medical wards. Antihypertensive medication prescription preceding pressure increase was observed in 578 patients (22.8%. Nifedipine was used in 553 (95.7% and captopril in 25 (4.3%. In 50.7% of patients, prescription of antihypertensive medication was not associated with maintained antihypertensive medication. Prescription of antihypertensive drugs preceding elevation of blood pressure was significantly (p<0.001 more frequent on the surgical floor (27.5%; 405/1468 than on the medical floor (14.3%; 117/818. The frequency of prescription of antihypertensive drugs preceding elevation of blood pressure without maintained antihypertensive drugs and the ratio between the number of prescriptions of nifedipine and captopril were greater in surgical wards. CONCLUSION: The use of antihypertensive medication, preceding elevation of blood pressure (22.8% observed in admitted patients is not supported by scientific evidence. The high frequency of this practice may be even greater in nonuniversity hospitals.

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).

    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.

    Full Text Available BACKGROUND: We conducted an Internet-based randomized trial comparing three valence framing presentations of the benefits of antihypertensive medication in preventing cardiovascular disease (CVD for people with newly diagnosed hypertension to determine which framing presentation resulted in choices most consistent with participants' values. METHODS AND FINDINGS: In this second in a series of televised trials in cooperation with the Norwegian Broadcasting Company, adult volunteers rated the relative importance of the consequences of taking antihypertensive medication using visual analogue scales (VAS. Participants viewed information (or no information to which they were randomized and decided whether or not to take medication. We compared positive framing over 10 years (the number escaping CVD per 1000; negative framing over 10 years (the number that will have CVD and negative framing per year over 10 years of the effects of antihypertensive medication on the 10-year risk for CVD for a 40 year-old man with newly diagnosed hypertension without other risk factors. Finally, all participants were shown all presentations and detailed patient information about hypertension and were asked to decide again. We calculated a relative importance score (RIS by subtracting the VAS-scores for the undesirable consequences of antihypertensive medication from the VAS-score for the benefit of CVD risk reduction. We used logistic regression to determine the association between participants' RIS and their choice. 1,528 participants completed the study. The statistically significant differences between the groups in the likelihood of choosing to take antihypertensive medication in relation to different values (RIS increased as the RIS increased. Positively framed information lead to decisions most consistent with those made by everyone for the second, more fully informed decision. There was a statistically significant decrease in deciding to take antihypertensives on

  11. High blood pressure, antihypertensive medication and lung function in a general adult population

    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

    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 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.

    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.

    Purpose To compare the use of antihypertensive medications and diagnostic tests among adolescents and young adults with primary vs. secondary hypertension Methods We conducted retrospective cohort analysis of claims data for adolescents and young adults (12–21 years) 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 presence of obesity-related comorbidities. For the subset receiving antihypertensive medications, we examined their diagnostic test use (echocardiograms, renal ultrasounds, and electrocardiograms (EKG)). Results Study sample included 1232 adolescents and young adults; 84% had primary hypertension and 16% had secondary hypertension. Overall prevalence rate of hypertension was 2.6%. One-quarter (28%) with primary hypertension had ≥1 antihypertensive medication whereas 65% with secondary hypertension had ≥1 antihypertensive medication. Leading prescribers of antihypertensives for subjects with primary hypertension were primary care physicians (PCP) (80%) whereas antihypertensive medications were equally prescribed by PCPs (43%) and subspecialists (37%) for subjects with secondary hypertension. Conclusions The predominant hypertension diagnosis among adolescents and young adults is primary hypertension. Antihypertensive medication use was higher among those with secondary hypertension compared to 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 vs. secondary hypertension.

    Adherence to antihypertensive medications is often less than optimal. Research suggests that patients have limited confidence regarding whether office blood pressure (BP) assessments represent their 'true' BP, which may further promote poor adherence to BP-lowering medication. We assessed peoples' confidence in the methods of BP assessment and examined the associations between patients' confidence levels and medication adherence comparing office and home BP-monitoring techniques. We surveyed US adults aged 30 years or older (N=1010), all of whom had undergone an office BP measurement within the past 6 months. Respondents who indicated being prescribed antihypertensive medication (N=429) were asked to indicate their level of confidence on a 1-9 scale that BP measurements represented their true BP, and their adherence to antihypertensive medication using the eight-item Morisky Medical Adherence Scale (MMAS-8). Respondents had equal confidence that both office BP measurements and home monitoring measurements reflected their true BP (median=7). Respondents indicated that they would have slightly more confidence in ambulatory BP monitoring (median=8). As respondents' confidence in the assessments of BP from office measurements and home monitoring increased from 1 to 9, the mean MMAS-8 score, adjusted for age, race, and education, increased from 5.38 to 6.25 (P=0.053) and from 5.50 to 6.14 (P=0.25), respectively. As patients' confidence in a BP assessment method increases, so too does their reported adherence to prescribed antihypertensive medications. This finding further supports the incorporation of methods in which patients can feel confident that the measurements are representative of their 'true' BP.

    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.

Research has focused primarily on poorly controlled HTN, negative belief systems, and nonadherence factors that hinder blood pressure control. No known research studies underscore predominantly Black women who report consistent adherence to their antihypertensive medication-taking. The purpose of this study was to describe self-care management strategies used by Black women who self-report consistent adherence to their antihypertensive medication and to determine the existence of further participation in lifestyle modifications, such as eating a healthy diet and increasing physical activity.Methods: Using a qualitative descriptive design, four focus groups with a total of 20 Black women aged 25–71 years were audio-taped. Transcripts were analyzed using qualitative content analysis. Participants were included in the study if they scored perfect adherence on the medication subscale of the Hill–Bone Compliance to High Blood Pressure Therapy Scale.Results: Medication adherence was predicated on three themes: HTN experience, involvement with treatment regimen, and a strong motivated mentality. Black women would benefit from treatment approaches that are sensitive to 1 diverse emotional responses, knowledge levels, and life experiences; 2 two-way communication and trusting, collaborative relationships with active involvement in the treatment regimen; 3 lifestyle modifications that focus on health benefits and individual preferences; and 4 spiritual/religious influences on adherence.Conclusion: The use

    Postoperative acute kidney injury (AKI) is frequent after major vascular surgery and is associated with significant morbidity and mortality. It remains unclear whether the administration of combined oral antihypertensive medications on the day of surgery can increase the risk of postoperative AKI. We performed a retrospective cohort study of hypertensive patients undergoing elective major vascular surgery to determine the association between the number of antihypertensive medications continued on the morning of surgery and AKI at 48 hours postoperatively. A total of 406 patients who had undergone suprainguinal vascular surgery were included, and 10.3% suffered postoperative AKI. In multivariable analysis, the number of antihypertensive medications taken on the morning of surgery was independently associated with AKI (P = .026). Compared with patients who took no medication, taking one medication (adjusted odds ratio [aOR], 1.58; 95% confidence interval [CI], 0.68-3.75) and taking two or more medications (aOR, 2.70; 95% CI, 1.13-6.44) were associated with a 1.6-fold and 2.7-fold increased risk of postoperative AKI, respectively. Other predictors of AKI were suprarenal surgery (aOR, 3.37; 95% CI, 1.53-7.44), age (aOR, 2.29 per 10 years; 95% CI, 1.40-3.74), length of surgery (aOR, 1.40 per 1 hour; 95% CI, 1.10-1.76), hemoglobin drop (aOR, 1.37 per 10 g/L; 95% CI, 1.10-1.74), and history of coronary artery disease (aOR, 2.33; 95% CI, 1.08-5.00). In patients undergoing major vascular surgery who are treated with chronic antihypertensive therapy, the administration of antihypertensive drugs on the morning of surgery is independently associated with an increased risk of postoperative AKI. Further prospective studies are needed to confirm this finding. Copyright © 2017 Society for Vascular Surgery. Published by Elsevier Inc. All rights reserved.

    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

    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.

    To assess the prevalence of hypertension, elevated blood pressure and cardiovascular risk factors among HIV-positive individuals in rural Rakai District, Uganda. We assessed 426 HIV-positive individuals in Rakai, Uganda from 2007 to 2010. Prevalence of hypertension and elevated blood pressure assessed by clinical measurement was compared to clinician-recorded hypertension in case report forms. Multiple logistic regression and z-tests were used to examine the association of hypertension and elevated blood pressure with age, sex, body mass index (BMI), CD4 cell count and antiretroviral treatment (ART) use. For individuals on antihypertensives, medication utilisation was reviewed. The prevalence of hypertension (two elevated blood pressure readings at different time points) was 8.0% (95% CI: 5.4-10.6%), and that of elevated blood pressure (one elevated blood pressure reading) was 26.3% (95% CI: 22.1-30.5%). Age ≥50 years and higher BMI were positively associated with elevated blood pressure. ART use, time on ART and CD4 cell count were not associated with hypertension. Eighty-three percent of subjects diagnosed with hypertension were on antihypertensive medications, most commonly beta-blockers and calcium channel blockers.

    Full Text Available Abstract Background: Hypertension is the most prevalent risk factor for cardiovascular disease, and its proper control can prevent the high morbidity and mortality associated with this disease. Objective: To assess the degree of compliance of antihypertensive prescriptions with the VI Brazilian Guidelines on Hypertension and the blood pressure control rate in primary care. Methods: Cross-sectional study conducted between August 2011 and November 2012, including 332 adults ≥ 45 years registered in the Family Doctor Program in Niteroi and selected randomly. The analysis included the prescribed antihypertensive classes, doses, and frequencies, as well as the blood pressure (BP of the individuals. Results: The rate of prescription compliance was 80%. Diuretics were the most prescribed medications, and dual therapy was the most used treatment. The most common non-compliances were underdosing and underfrequencies. The BP goal in all cases was < 140/90 mmHg, except for diabetic patients, in whom the goal was set at < 130/80 mmHg. Control rates according to these goals were 44.9% and 38.6%, respectively. There was no correlation between prescription compliance and BP control. Conclusions: The degree of compliance was considered satisfactory. The achievement of the targets was consistent with national and international studies, suggesting that the family health model is effective in BP management, although it still needs improvement.

    Full Text Available Neuromolecular Imaging (NMI with novel biosensors enables the selective detection of neurotransmitters in vivo within seconds, on line and in real time. Biosensors remain in place for continuing studies over a period of months. This biotechnological advance is based on conventional electrochemistry; the biosensors detect neurotransmitters by electron transfer. Simply stated, biosensors adsorb electrons from each neurotransmitter at specific oxidation potentials; the current derived from electron transfer is proportional to neurotransmitter concentration. Selective electron transfer properties of these biosensors permit the imaging of neurotransmitters, metabolites and precursors. The novel BRODERICK PROBE® biosensors we have developed, differ in formulation and detection capabilities from biosensors/electrodes used in conventional electrochemistry/ voltammetry. In these studies, NMI, specifically, the BRODERICK PROBE® laurate biosensor images neurotransmitter signals within mesolimbic neuronal terminals, nucleus accumbens (NAc; dopamine (DA, serotonin (5-HT, homovanillic acid (HVA and Ltryptophan (L-TP are selectively imaged. Simultaneously, we use infrared photobeams to monitor open-field movement behaviors on line with NMI in the same animal subjects. The goals are to investigate integrated neurochemical and behavioral effects of cocaine and caffeine alone and co-administered and further, to use ketanserin to decipher receptor profiles for these psychostimulants, alone and co-administered. The rationale for selecting this medication is: ketanserin (a is an antihypertensive and cocaine and caffeine produce hypertension and (b acts at 5-HT2A/2C receptors, prevalent in NAc and implicated in hypertension and cocaine addiction. Key findings are: (a the moderate dose of caffeine simultaneously potentiates cocaine's neurochemical and behavioral responses. (b ketanserin simultaneously inhibits cocaine-increased DA and 5-HT release in

    There is an established association between hypertension and increased risk of poor cognitive performance and dementia including Alzheimer's disease; however, associations between antihypertensive medications (AHM) and dementia risk are less clear. An increased interest in AHM has resulted in expanding publications; however, none of the recent reviews provide comprehensive review. Our extensive review includes 24 mechanistic animal and human studies published over the last 5 years assessing relationship between AHM and cognitive function. All classes of AHM showed similar result patterns in animal studies. The mechanism by which AHM exert their effect was extensively studied by evaluating well-established pathways of AD disease process, including amyloid beta (Aβ), vascular, oxidative stress and inflammation pathways, but only few studies evaluated the blood pressure lowering effect on the AD disease process. Methodological limitations of the studies prevent comprehensive conclusions prior to further work evaluating AHM in animals and larger human observational studies, and selecting those with promising results for future RCTs.

    Low adherence to antihypertensive medication has been hypothesized to increase visit-to-visit variability (VVV) of blood pressure (BP). We assessed the association between antihypertensive medication adherence and VVV of BP in the Antihypertensive and Lipid-Lowering Treatment to Prevent Heart Attack Trial (ALLHAT). VVV of BP was calculated using SD independent of mean, SD, and average real variability across study visits conducted 6 to 28 months after randomization. Participants who reported taking heart disease or nonfatal myocardial infarction, stroke, heart failure, or mortality risk. In conclusion, improving medication adherence may lower VVV of BP. However, VVV of BP is associated with cardiovascular outcomes independent of medication adherence. © 2016 American Heart Association, Inc.

    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.

    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.

    The authors estimated the costs and cost savings of implementing a program of mailed practice guidelines and single-visit individual and group academic detailing interventions in a randomized controlled trial to improve the use of antihypertensive medications. Analyses took the perspective of the payer. The total costs of the mailed guideline, group detailing, and individual detailing interventions were estimated at 1000 dollars, 5500 dollars, and 7200 dollars, respectively, corresponding to changes in the average daily per person drug costs of -0.0558 dollars (95% confidence interval, -0.1365 dollars to 0.0250 dollars) in the individual detailing intervention and -0.0001 dollars (95% confidence interval, -0.0803 dollars to 0.0801 dollars) in the group detailing intervention, compared with the mailed intervention. For all patients with incident hypertension in the individual detailing arm, the annual total drug cost savings were estimated at 21,711 dollars (95% confidence interval, 53,131 dollars savings to 9709 dollars cost increase). Information on costs of academic detailing could assist with health plan decision making in developing interventions to improve prescribing.

    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.

     Arterial hypertension is among the leading risks for mortality. This burden requires in hypertensive patients the use of single, double or more antihypertensive drugs. The relationship between intracranial pressure (ICP) and arterial blood pressure is complex and still under debate. The impact of antihypertensive drugs on ICP is unknown. We wanted to understand whether the use of antihypertensive drugs has a significant influence on ICP and cerebrospinal fluid (CSF)/brain related parameters. In a cohort of 95 patients with suspected normal pressure hydrocephalus, we prospectively collected drug details according to the Anatomical Therapeutic Chemical (ATC) classification. Lumbar infusion studies were performed. Using ICM+ software, we calculated at baseline and plateau ICP and pulse amplitude, resistance to CSF outflow, elastance, and pressure in the sagittal sinus and CSF production rate. We studied the influence of the administration of 1, 2, 3 or more antihypertensive drugs on ICP-derived parameters. We compared the data using Student's and Mann-Whitney tests or Chi-squared and Fisher's exact test.  Elastance is significantly higher in patients with at least one antihypertensive drug compared with patients without medication. On the contrary, pressure volume index (PVI) is significantly decreased in patients with antihypertensive drugs compared with patients not on these medications. However, the number of antihypertensive drugs does not seem to influence other ICP parameters.  Patients on antihypertensive drugs seem to have a stiffer brain than those not on them.

    To compare population-level baseline characteristics, individual-level utilization, and costs between antihypertensive medication users versus nonusers in adults with diabetes and concomitant hypertension. This longitudinal retrospective observational research used Medical Expenditure Panel Survey household component pooled years 2006 to 2009 to analyze adults 18 years or older with nongestational diabetes and coexistent essential hypertension. Two groups were created: 1) antihypertensive medication users and 2) no antihypertensive pharmacotherapy. We examined average annualized health care costs and emergency department and hospital utilization. Accounting for Medical Expenditure Panel Survey's complex survey design, all analyses used longitudinal weights. Logistic regressions examined the likelihood of utilization and anytihypertensive medication use, and log-transformed multiple linear regression models assessed costs and antihypertensive medication use. Of the 3261 adults identified with diabetes, 66% (n = 2137) had concomitant hypertension representing 38.7 million individuals during 2006 to 2009. Significantly, the 16% (n = 338) no antihypertensive pharmacotherapy group showed greater mean nights hospitalized (3.6 vs. 1.7, P = 0.0120), greater all-cause hospitalization events per 1000 patient months (41 vs. 24, P = 0.0.007), and lower mean diabetes-related and hypertension-related ambulatory visits. After adjusting for confounders, non-antihypertensive medication users showed 1.64 odds of hospitalization, 29% lower total, and 27% lower average annualized medical expenses compared with antihypertensive medication users. In adults with diabetes and coexistent hypertension, we observed significantly greater hospitalizations and lower costs for the non antihypertensive pharmacotherapy group versus those using antihypertensive medications. The short-term time horizon greater hospitalizations with lower expenses among non-antihypertensive medication users with

    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.

    Full Text Available Background. We undertake a systematic review and meta-analysis to evaluate the effect of preoperative hypertension and preoperative antihypertensive medication to postoperative atrial fibrillation (POAF in patients undergoing cardiac surgery. Methods. We searched PubMed, Embase, and Cochrane Library (from inception to March 2016 for eligible studies. The outcomes were the effects of preoperative hypertension, preoperative calcium antagonists regimen, preoperative ACE inhibitors regimen, and preoperative beta blocking agents regimen with POAF. We calculated pooled risk ratios (OR and 95% CIs using random- or fixed-effects models. Results. Twenty-five trials involving 130087 patients were listed. Meta-analysis showed that the number of preoperative hypertension patients in POAF group was significantly higher (P<0.05, while we found that there are no significant differences between two groups in Asia patients by subgroup analysis, which is in contrast to other outcomes. Compared with the Non-POAF group, the number of patients who used calcium antagonists and ACE inhibitors preoperatively in POAF group was significantly higher (P<0.05. And we found that there were no significant differences between two groups of preoperative beta blocking agents used (P=0.08. Conclusions. Preoperative hypertension and preoperative antihypertensive medication in patients undergoing cardiac operations seem to be associated with higher risk of POAF.

    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

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.

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

    Background Text messages can improve medication adherence and outcomes in several conditions. For this study, experts developed text messages addressing determinants of medication adherence: disease beliefs, medication necessity, medication concerns, and forgetfulness, as well as positive reinforcement messages for patients who were adherent. Objectives To validate expert-developed text messages to address medication non-adherence with a group of non-researchers. Methods A two-wave, card-sorting activity was conducted with students and staff at the University of Michigan. In the first wave, 40 participants grouped 32 messages addressing barriers for medication adherence (disease beliefs, medication necessity, medication concerns, and forgetfulness) according to their perceived relationship. Messages with poor grouping agreement were deleted or modified. In the second wave, positive reinforcement messages were developed and tested along with the previous categories (36 messages) by 37 participants. Similarity and cluster analyses were used to assess agreement between experts and participants. Results In the first card-sorting wave, participants grouped messages into between 2 and 13 separate categories. Similarity analysis showed four groupings of messages, however, some had an agreement below 50% and clusters appeared dispersed. In the second wave, and after messages being edited, participants grouped the messages into between 4 and 9 categories. Five groups (now including positive reinforcement messages) were identified with higher agreement in the similarity and cluster analyses. Conclusions The structure of expert-developed text messages to address medication adherence key barriers was confirmed. Messages will be used in future research to determine their impact on affecting medication adherence to anti-hypertensive medications using a reinforcement learning controlled text messaging service.

    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.

    Full Text Available Abstract Background We conducted a systematic review of evidence from randomized controlled trials to answer the following research question: What are the relative effects of different classes of antihypertensive drugs in reducing the incidence of cardiovascular disease outcomes for healthy people at risk of cardiovascular disease? Methods We searched MEDLINE, EMBASE, AMED (up to February 2011 and CENTRAL (up to May 2009, and reference lists in recent systematic reviews. Titles and abstracts were assessed for relevance and those potentially fulfilling our inclusion criteria were then assessed in full text. Two reviewers made independent assessments at each step. We selected the following main outcomes: total mortality, myocardial infarction and stroke. We also report on angina, heart failure and incidence of diabetes. We conducted a multiple treatments meta-analysis using random-effects models. We assessed the quality of the evidence using the GRADE-instrument. Results We included 25 trials. Overall, the results were mixed, with few significant dif-ferences, and with no drug-class standing out as superior across multiple outcomes. The only significant finding for total mortality based on moderate to high quality evidence was that beta-blockers (atenolol were inferior to angiotensin receptor blockers (ARB (relative risk (RR 1.14; 95% credibility interval (CrI 1.02 to 1.28.

    Despite a variety of efficient and cost-effective antihypertensive medication, hypertension remains a serious health and economic burden. High consumption of cardiovascular drugs in the Slovak Republic does result neither in better hypertension control nor in significant decrease in cardiovascular mortality. At the same time, Slovakia has alarmingly low patients' adherence to medication intake. Studies have shown the efficiency of short messaging service (SMS) reminders to improve patients' adherence and health outcomes at low costs. Since SMS is popular among Slovaks, this approach may be feasible also in Slovakia. The primary objective is to assess if daily SMS reminders of antihypertensive medication intake provided by pharmacists in addition to the standard pharmaceutical care increase the proportion of adherent older hypertensive ambulatory patients. The SPPA trial is a pragmatic randomized parallel group (1:1) trial in 300 older hypertensive patients carried out in community pharmacies in Slovakia. Trial pharmacies will be selected from all main regions of Slovakia. Trial intervention comprises daily personalized SMS reminders of medication intake embedded into usual pharmaceutical practice. The primary outcome is a combined adherence endpoint consisting of subjective self-reported medication adherence via the eight-item Morisky Medication Adherence Scale (MMAS-8) and objective pill count rate. Secondary outcomes include: change in the MMAS-8; comparison of adherence rates using pill count; change in systolic blood pressure; and patient satisfaction. Also, direct treatment costs will be evaluated and a cost-effectiveness analysis will be carried out. The SPPA trial engages community pharmacists and mobile health (mHealth) technologies via evidence-based pharmaceutical care to efficiently and cost-effectively addresses current main healthcare challenges: high prevalence of hypertension; overconsumption of cardiovascular medicines; low adherence to medication

    Full Text Available Introduction: Drug-drug interactions remain a major cause of adverse drug reactions with great consequences such as increased morbidity and increased healthcare cost. In elderly patients with systemic hypertension, there is a tendency for them to be prescribed multiple medications and this may expose them to some drug-drug interactions (DDIs especially in the context of physiological changes of ageing. The objective of this study was to evaluate potential drug-drug interaction among some Nigerian elderly hypertension. Methods: A cross-sectional study involving elderly hypertensive patients attending the general outpatient clinic of two tertiary healthcare facilities located in Ekiti State, South-West Nigeria. The information collected from the patients′ medical records included their ages, gender, diagnosis and list of prescribed anti-hypertensive medications. Potential drug-drug interactions were checked for using the Multi-Drug Interaction Checker (Medscape Reference and Epocrates Drug Interaction Checker (San Mateo CA, USA. Results: A total of 350 elderly patients attended the clinics during the study period of which 208 (59.4% hypertensive patients were identified and their records used for analysis. The fixed-dose combination drug Moduretic® (Amiloride /Hydrochlorothiazide-25.7% was the most commonly prescribed antihypertensive followed by Lisinopril (16.6%, Amlodipine (13.2% and Nifedipine (12.6%. The anti-platelet Acetyl-salicylic acid (ASA was prescribed for 100 (48.1% patients and represented 19.8% of all prescribed medications. A total of 231 potential DDIs were found among the patients giving a mean of 1.3 interactions per patient. The most common identified drug pairs with potential interactions were ACE inhibitors - Amiloride, followed by ACE inhibitors - Hydrochlorothiazide, ACE inhibitors - ASA and ARB - Amiloride. Conclusion: Potential drug-drug interactions, though common in this study comprised mainly of minor and moderate

  2. Personal view: cost and benefit of medical rituals in gastroenterology.

    Sonnenberg, A

    2004-11-01

    Unable to resolve a medical problem, gastroenterologists occasionally choose an ineffectual intervention instead. The elusive path to effectual management becomes substituted with an ineffectual but readily available medical ritual. The term 'ritual' refers to the utilization of an ineffectual intervention with little chances of achieving a medically relevant goal. The aim of the article is to analyse the cost-benefit relationship of rituals in gastroenterology and the reasons why gastroenterologists utilize them. Ritualistic disease management is described in terms of medical decision and threshold analysis. If the perceived benefit of a ritual exceeds its cost, the ineffectual path becomes more attractive than expectant management or doing nothing. To engage in an ineffectual intervention, the threshold probability for success needs to exceed its cost-benefit difference divided by the benefit associated with success. In choosing an ineffectual intervention, doctors tend to underestimate the true costs of a ritual and overestimate its probability of success. The availability of an effectual path leads to more stringent conditions for the benefit associated with an ineffectual path. A better understanding of their economical underpinnings should lead to more restricted utilization of rituals in gastroenterology, especially, in situations where they drain scarce resources disproportionately to their perceived benefit.

    Elliott; Prisant

    1997-12-01

    During the late 1980s and early 1990s, much research effort in the pharmaceutical industry was focused on the development of novel systems for sustained delivery of effective, but intrinsically short-acting, antihypertensive agents. This advance was motivated by a desire both to improve trough/peak ratios (as suggested by the US Food and Drug Administration [FDA]) and also to protect the proprietary patient life for older agents that would otherwise be susceptible to generic substitution. Additional benefits of such sustained-release systems include: improved side-effect profiles, shorter time from development to regulatory approval (because of the already established safety record of the immediate-release compound), improved compliance with medication, and reduced administrative cost. The latter two are presumably related to the fact that patients generally have to use fewer doses of sustained-release than immediate-release preparations. Disadvantages include: generally higher per-dose cost (which includes a licensing fee for the patented delivery system), altered efficacy and potential problems in patients with abnormal absorptive surfaces (gut or skin), and altgered first-pass metabolism rates (compared with immediate-release preparations). Some of the novel drug delivery systems that have already received FDA approval include: alginate matrix, Geomatrix, several formulations of pellet-based systems, several transdermal systems, and the Gastrointestinal therapeutic system (GITS), which releases the pharmacologically active agent at a predictable rate. A novel variant of this last system has been developed, based on the idea that the peak serum concentration of antihypertensive medication will occur just before or at the time of the greatest change in blood pressure (ie, the few hours around awakening). Data are now being gathered to convince authorities that this theoretically advantageous delivery system will be as effective in reducing rates of cardiovascular

    2017-12-01

    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.

  7. 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.

    '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.

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

  11. Medical abortion in primary care: pitfalls and benefits.

    Science.gov (United States)

    Boersma, A A; Meyboom-de Jong, B

    2009-12-01

    We describe five pitfalls of medical abortion: ectopic pregnancy not terminated after misoprostol, but without negative side-effects; long-term vaginal blood loss with suspicious retained products which disappeared spontaneously; a patient with uterus myomatatosus with severe pain and retained products in the uterus; repetition of misoprostol because of retained products in the uterus after two weeks and an allergic reaction to methotrexate. Despite these pitfalls, there are enough benefits to consider medical abortion with methotrexate and misoprostol as a safe method with a high success rate of more than 91% and a good alternative for surgical abortion. An invasive procedure is not necessary, there are no long-term complications and it can be performed at an earlier stage, which makes it more acceptable in society. In Curaçao, where abortion is legally restricted, medical abortion is performed with methotrexate and misoprostol. In countries where abortion is legal, mifepristone and misoprostol are the first choice.

    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.

    Full Text Available The evidence on the relationship between breast cancer and different types of antihypertensive drugs taken for at least 5 years is limited and inconsistent. Furthermore, the debate has recently been fueled again with new data reporting an increased risk of breast cancer among women with a long history of use of antihypertensive drugs compared with nonusers.In this case-control study, we report the antihypertensive drugs-breast cancer relationship in 1,736 breast cancer cases and 1,895 healthy controls; results are reported stratifying by the women's characteristics (i.e., menopausal status or body mass index category tumor characteristics and length of use of antihypertensive drugs.The relationship among breast cancer and use of calcium channel blockers (CCB for 5 or more years had odds ratio (OR = 1.77 (95% CI, 0.99 to 3.17. Stratifying by BMI, the OR increased significantly in the group with BMI ≥ 25 (OR 2.54, 95% CI, 1.24 to 5.22. CCBs were even more strongly associated with more aggressive tumors, (OR for invasive tumors = 1.96, 95% CI = 1.09 to 3.53; OR for non ductal cancers = 3.97, 95% CI = 1.73 to 9.05; OR for Erbb2+ cancer = 2.97, 95% CI: 1.20 to 7.32. On the other hand, premenopausal women were the only group in which angiotensin II receptor blockers may be associated with breast cancer (OR = 4.27, 95% CI = 1.32 to 13.84 but this could not be identified with any type or stage. Use of angiotensin-converting-enzyme inhibitors, beta blockers and diuretics were not associated with risk.In this large population-based study we found that long term use of calcium channel blockers is associated with some subtypes of breast cancer (and with breast cancer in overweight women.

    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.

  17. Profiling Antihypertensive Therapy.

    Mandal, Anil K.

    The objectives of treating hypertension are to achieve adequate control of blood pressure (BP) and maintain it under tight control. Maintenance of tight control of BP will most likely prevent stroke, heart attack, and heart failure, cause regression of left ventricular hypertrophy, and quite possibly preserve or improve renal function. The last two salutary effects combined will further reduce the morbidity and mortality in the treated hypertensive subjects. Choice of antihypertensive drugs is of significant importance so that our efforts to control hypertension do not grossly alter the quality of life. The cost of therapy is also an important consideration. Thus, thiazide diuretics, beta-blockers, and central inhibitors that are relatively inexpensive and adequately lower BP should be a common choice. However, if drowsiness interferes with work, or impotence becomes a threat for the marital partner or significant other, adjustment has to be made. The metabolic abnormalities consisting mainly of impaired glucose tolerance, hypercholesterolemia, and insulin resistance often induced by these relatively inexpensive drugs have put calcium channel blocker and ACE inhibitor group of drugs on the top of the list for antihypertensive therapy. They are far more expensive, yet offer no greater antihypertensive advantage than a diuretic or central inhibitor, except in special circumstances.

    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.

  19. Elevated N-terminal pro-brain natriuretic peptide levels predict an enhanced anti-hypertensive and anti-proteinuric benefit of dietary sodium restriction and diuretics, but not angiotensin receptor blockade, in proteinuric renal patients.

    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.

    Chronic hypertension, particularly midlife high blood pressure, has been associated with an increased risk for cognitive decline and dementia. In this context, antihypertensive drugs might have a preventive effect, but the association remains poorly understood. The aim of this systematic review was to examine all published findings that investigated this relationship and discuss the mechanisms underlying the potential benefits of antihypertensive medication use. A literature search was conducted using MEDLINE, Embase, and the Cochrane Library for publications from 1990 onwards mentioning hypertension, antihypertensive drugs, cognitive decline, and dementia. A total of 38 relevant publications, corresponding to 18 longitudinal studies, 11 randomized controlled trials, and nine meta-analyses were identified from the 10,251 articles retrieved in the literature search. In total, 1,346,176 subjects were included in these studies; the average age was 74 years. In the seven longitudinal studies assessing the effect of antihypertensive medication on cognitive impairment or cognitive decline, antihypertensive drugs appeared to be beneficial. Of the 11 longitudinal studies that assessed the effect of antihypertensive medication on incidence of dementia, only three did not find a significant protective effect. Antihypertensive medication could decrease the risk of not only vascular dementia but also Alzheimer's disease. Four randomized controlled trials showed a potentially preventive effect of antihypertensive drugs on the incidence of dementia or cognitive decline: SYST-EUR (Systolic Hypertension in Europe Study) I and II, with a 55% reduction in dementia risk (3.3 vs. 7.4 cases per 1,000 patient years; pPrevention Evaluation), with a 41% reduction in cognitive decline associated with stroke (95% confidence interval [CI] 6-63); and PROGRESS (Perindopril Protection against Recurrent Stroke Study), with a 19% reduction in cognitive decline (95% CI 4-32; p=0.01).

    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.

    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.

The content was determined by observations and based on authors’ professional experience. The starting point of a medical English course is a thorough analysis of students’ needs, which is then used in course design and definition of appropriate learning goals. The student is at the center of learning and it is necessary to establish a positive cooperation between students and teachers. As medical English course is highly context-based, the inclusion of medical teachers can offer many opportunities for a successful learning process.

    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.

    2017-01-01

    Full Text Available Background: Hypertension has been reported to be the strongest modifiable global risk factor for cardiovascular morbidity, mortality as well as health burdens. Antihypertensive pharmacotherapy effectively reduces hypertension-related morbidity and mortality. Prescribing pattern surveys are one of the drug use evaluation techniques providing an unbiased picture and identification of suboptimal prescribing patterns. Objective: The 6-month cross-sectional study was designed to assess the prescription pattern and cost of antihypertensives therapy in a health-care resource-limited setting of India. Materials and Methods: The hypertensive patients were divided into two groups according to risk assessment using the World Health Organization and International Society of Hypertension guidelines for the management of hypertension. The average drug acquisition and the percentage expenditure costs were calculated for each drug class on a daily and annual basis, and InStat GraphPad Prism was the statistical tool used. Results: In our study of 100 patients, the most commonly prescribed antihypertensives were calcium channel blockers in 49.81% and beta-blockers in 12.73% patients, respectively. The cost analysis on antihypertensive medications utilized showed a total expenditure of Rs. 3823.58 invested in 1 year. Conclusion: The drug use pattern of antihypertensives was evidenced based but imposed economic burden in patients. Hence, rational use of generic medications was recommended.

This idea was taken a step further with the concept of the Polypill™. There are, however, considerable patent, pharmacokinetic, pharmacodynamic, registration, and cost implications that will need to be overcome before the Polypill™ or other single-pill combinations of CV medications become widely available. However, a medication targeting blood pressure (BP and lipids provides much of the proposed benefits of the Polypill™. A single-pill combination of the antihypertensive amlodipine besylate and the lipid-lowering medication atorvastatin calcium (SPAA is currently available in many parts of the world. This review describes the rationale for this combination therapy and the clinical trials that have demonstrated that these two agents can be combined without the loss of efficacy for either agent or an increase in the incidence of adverse events. The recently completed Cluster Randomized Usual Care vs Caduet Investigation Assessing Long-term-risk (CRUCIAL trial is discussed in detail. CRUCIAL was a 12-month, international, multicenter, prospective, open-label, parallel design, cluster-randomized trial, which demonstrated that a proactive intervention strategy based on SPAA in addition to usual care (UC had substantial benefits on estimated CV risk, BP, and lipids over continued UC alone. Adherence with antihypertensive and lipid-lowering therapies outside of the controlled environment of clinical trials is very low (~30%–40% at 12 months. Observational studies have demonstrated that improving adherence to lipid-lowering and antihypertensive medications may reduce CV events. One means of improving adherence is the use of single-pill combinations. Real-world observational

    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.

    Wagner, Louis K

    2011-11-01

    Frequently messages are conveyed about benefit and risk in medical imaging or in imaging-guided medical intervention that are quite different from the intended communication. This is because communication is not merely the words used to express an idea. The message involves many personal factors on the part of the communicator and on the part of the audience. The intent of this article is to disclose some of the underlying factors that disproportionately bias communication of benefit and risk. Suggestions on how to develop a holistic communication of benefits and risks are presented. It is recommended that communication about the application of radiation to patients be disassociated from standard radiation protection concepts. The medical profession should develop unique communication tools to deliver a message that focuses on benefit/risk as a holistic entity, not benefit or risk as separate entities.

    This paper presents a pilot study of benefits derived from information and communications technology(ICT) adoption and use in medical practices in regional Australia. The study involved 122 regional medical practitioners. The results show that like the more general small business sector, the perception of certain benefits is associated with the size of the practice (in terms of employee levels) and/or the gender of the respondent practitioner. The data also showed that the level of skill of certain software used within the practice was significantly associated with the level of perceived benefit derived from ICT adoption and use.

    A medical consultant advises his company such that the persons insured receive the medically necessary benefits agreed in their insurance contract and thus are offered very good medical treatment. But it is also in the interests of all those insured to identify those treatments that are neither indicated, effective, nor medically necessary, as well as treatments which may prove dangerous to patients or result in overtreatment. Based on a representative sample, the present study examines which sums are not reimbursed due to this approach. The medical fields to be considered in particular are also addressed. It was found that the medical necessity of artificial insemination, alternative treatments, medications, innovative treatment methods and debatable cosmetic treatments, and certain other fields of consultation, would be worth investigating in particular. About 7 million € could have been saved in 2014 as a result of the advice from the medical consultant.

    Chlorogenic acids (CGAs) are potent antioxidants found in certain foods and drinks, most notably in coffee. In recent years, basic and clinical investigations have implied that the consumption of chlorogenic acid can have an anti-hypertension effect. Mechanistically, the metabolites of CGAs attenuate oxidative stress (reactive oxygen species), which leads to the benefit of blood-pressure reduction through improved endothelial function and nitric oxide bioavailability in the arterial vasculature. This review article highlights the physiological and biochemical findings on this subject and highlights some remaining issues that merit further scientific and clinical exploration. In the framework of lifestyle modification for the management of cardiovascular risk factors, the dietary consumption of CGAs may hold promise for providing a non-pharmacological approach for the prevention and treatment of high blood pressure.

    Falls are common during hospital admissions and may occur more frequently in patients who are taking antihypertensive medications, particularly in the context of normal to low blood pressure. The review and adjustment of these medications is an essential aspect of the post-fall assessment and should take place as soon as possible after the fall. Our aim was to investigate whether appropriate post-fall adjustments of antihypertensive medications are routinely made in a large National Health Service (NHS) Trust. Inpatient records over an eight-month period were captured from an electronic prescribing system to identify older adults (≥80 years old) with normal/low blood pressures (fall as these patients were considered to be at high risk of further falls. Prescribed antihypertensive medication on admission was then compared with the post-fall (within 24 h after the fall) and discharge prescriptions. A total of 146 patients were included in the analysis. Of those, 120 patients (82%) were taking the same number of antihypertensive medications in the 24 h after the fall as they were before; only 19 patients (13%) had a reduction in the number of medications and seven patients (5%) had an increase in medications during that period. Only 9% of the antihypertensive classes assessed were either stopped or reduced in dose immediately post-fall. In addition, 11 new antihypertensives were prescribed at this time. At discharge, half of the patients (n = 73) remained on the same number of antihypertensive medication as on admission, 51 patients (35%) were on fewer antihypertensives and 22 (15%) were on more. Additionally, no changes were made to individual antihypertensives in 49% of prescriptions; 34% were stopped or reduced in dose but 38 new agents were started by the time of discharge. Angiotensin converting enzyme inhibitors and angiotensin II receptor blockers (ACEi/ARB) were the class of medications most commonly stopped or reduced (51%). Antihypertensive

    Russ-Sellers, Rebecca; Blackwell, Thomas H

    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.

    In response to 2012 guidance in which the US Food and Drug Administration's (FDA) Center for Devices and Radiological Health (CDRH) stated the importance of patient-centric measures in regulatory benefit-risk assessments, the Medical Device Innovation Consortium (MDIC) initiated a project. The project was used to develop a framework to help the Food and Drug Administration (FDA) and industry sponsors understand how patient preferences regarding benefit and risk might be integrated into the review of innovative medical devices. A public-private partnership of experts from medical device industry, government, academia and non-profits collaborated on development of the MDIC patient centered benefit-risk framework. The MDIC Framework examines what patient preference information is and the potential use and value of patient preference information in the regulatory process and across the product development life cycle. The MDIC Framework also includes a catalog of patient preference assessment methods and an agenda for future research to advance the field. This article discusses key concepts in patient preference assessment of particular importance for regulators and researchers that are addressed in the MDIC Framework for patient centered benefit-risk assessment as well as the unique public-private collaboration that led its development.

    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.

    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

    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 Purpose: The purpose of the current study is to explore third- year medical students’ interest in learning about family planning, exposure to family planning (contraception and abortion and perceived barriers and benefits to family planning education in their obstetrics and gynecology rotation.Method: We conducted four focus groups with 27 third-year medical students near the end of their rotation in obstetrics and gynecology.Results: Students desired education in family planning but perceived limited exposure during their rotation. Most students were aware of abortion but lacked factual information and abortion procedural skills. They felt systemic and faculty-related barriers contributed to limited exposure. Students discussed issues such as lack of time for coverage of contraception and abortion in the curricula and rotation itself. Perceived benefits of clinical instruction in family planning included increased knowledge of contraceptive management and abortion the ability to care for and relate to patients, opportunity for values clarification, and positive changes in attitudes towards family planning.Conclusions: Medical students who desire full education in family planning during their obstetrics and gynecology rotation may face barriers to obtaining that education. Given that many medical students will eventually care for reproductive-age women, greater promotion of opportunities for exposure to family planning within obstetrics and gynecology rotations is warranted.

    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.

    2014-11-01

    A hip fracture is a debilitating condition that consumes significant resources in the United States. Surgical treatment of hip fractures can achieve better survival and functional outcomes than nonoperative treatment, but less is known about its economic benefits. We asked: (1) Are the societal benefits of hip fracture surgery enough to offset the direct medical costs? (2) Nationally, what are the total lifetime benefits of hip fracture surgery for a cohort of patients and to whom do these benefits accrue? We estimated the effects of surgical treatment for displaced hip fractures through a Markov cohort analysis of patients 65 years and older. Assumptions were obtained from a systematic literature review, analysis of Medicare claims data, and clinical experts. We conducted a series sensitivity analyses to assess the effect of uncertainty in model parameters on our estimates. We compared costs for medical care, home modification, and long-term nursing home use for surgical and nonoperative treatment of hip fractures to estimate total societal savings. Estimated average lifetime societal benefits per patient exceeded the direct medical costs of hip fracture surgery by USD 65,000 to USD 68,000 for displaced hip fractures. With the exception of the assumption of nursing home use, the sensitivity analyses show that surgery produces positive net societal savings with significant deviations of 50% from the base model assumptions. For an 80-year-old patient, the breakeven point for the assumption on the percent of patients with hip fractures who would require long-term nursing home use with nonoperative treatment is 37% to 39%, compared with 24% for surgical patients. Nationally, we estimate that hip fracture surgery for the cohort of patients in 2009 yields lifetime societal savings of USD 16 billion in our base model, with benefits and direct costs of USD 21 billion and USD 5 billion, respectively. For an 80-year-old, societal benefits ranged from USD 2 billion to

    To perform a cost-benefit analysis of brief medical advice to quit smoking in the Region of Murcia. A cost-benefit analysis is performed on brief medical advice to quit smoking versus non-intervention. A Markov model is used to estimate the costs (€ in 2014), under the perspective of the National Health System, and health outcomes. These are measured in quality-adjusted life years (QALY). The time horizon of the analysis is 20years, and costs and health outcomes were discounted at 3%. A univariate and multivariate deterministic sensitivity analysis is performed. Region of Murcia. Smokers in the Region of Murcia. Brief advice to quit smoking. Quality Adjusted Life Years (QALYs). With a time horizon of 5years (2018), the incremental cost-effectiveness ratio (ICER) would be €172,400 per QALY gained; at 10years (2023) the ICER was €30,300 per QALY gained; and, for the maximum horizon considered by the model, the ICER was €7,260 per QALY gained. Brief advice intervention is more efficient in the long-term than in the short-term and, depending on the Spanish cost-benefit threshold, public funding for this intervention would be recommended.

    2014-12-01

    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

    Drug promotion is one of the main factors that influence prescribing practices, but there are limited data available to quantify the relationship between drug advertising and prescription sales. To investigate the relationship between advertising for antihypertensive medicines and prescription sales in Australia between 1993 and 2002. Retrospective observational study. Advertising trends were monitored by counting the number of advertisements published in three Australian medical journals. Monthly prescription dispensing data were obtained from Drug Utilisation Sub-Committee and expressed as numbers of defined daily doses/1000 inhabitants/day. Linear regression and cross-correlations of time series were used in the analysis. The drug classes the most heavily advertised, angiotensin-converting enzyme inhibitors and calcium channel blockers, were also the most prescribed during the study period, while the drugs the least advertised, thiazide diuretics and beta-blockers, were the least used. In 5 of the 7 main antihypertensive classes, the product the most advertised was also the most prescribed. Other factors, such as the publication of large clinical trials, may have also influenced prescribing patterns. Prescription sales of antihypertensives in Australia are correlated with promotional advertising. The newest and most expensive medicines may be chosen over older effective drugs by prescribers. New policies on drug promotion control need to be developed.

    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.

    X-rays were discovered by Wilhelm Röntgen in 1895. Within one year, benefits of x-rays, such as visualization of fractures, and detriments, such as x-ray dermatitis, were recognized. Nobel Laureates Pierre and Marie Sklodowska Curie discovered the radioactive element radium in 1898, and a year later the application of radiation to cure cancer was reported. A significant price was paid for this: Marie Curie died of aplastic anemia related to her radiation exposure, and her daughter Irene Joliot Curie, Nobelist for radiochemical research, died of radiation-induced leukemia. Internationally developed radiation protection recommendations were formalized starting in the late 1920s. The increasing use of ionizing radiation in medical diagnosis and radiation therapy has brought significant societal benefits. Known risks of therapeutic radiation include coronary artery disease and secondary malignancy. However, recently concerns have been raised of possible very small but incremental increases in malignancies due to diagnostic medical radiation. Patients are largely unaware of, and referring physicians and even radiologists often underestimate, the carcinogenic effects of radiation. There is a need to determine the appropriateness of imaging tests that use ionizing radiation prior to performance; optimize imaging protocols to reduce unnecessary radiation; include patients in the decision process and encourage and enable them to track their radiation exposure; and promote education about medical radiation to patients, referring physicians, radiologists, and members of the public. The basic radiation protection principles of justification, optimization, and application of dose limits still pertain.

    Academic medical centers (AMCs) are the backbone of the U.S. health care system. They provide a disproportionate share of charity care and serve as a training ground for future physicians. Yet, AMCs face profound economic challenges, from changes in funding to changes in the health care market. To survive, many AMCs will need to form integrated health systems, a process expected to cost tens, if not hundreds, of millions of dollars. Nearly all AMCs are structured as not-for- profit entities, which places restrictions on their ability to forge partnerships, pursue joint ventures, and access private capital, often essential elements for forming such integrated systems. An alternative model known as the "for-benefit" corporation can allow AMCs to retain their important social mission and the other advantages of their not-for-profit status while allowing them flexibility and access to both investment and philanthropic capital. To pursue the for-benefit pathway, AMCs have two options-either they could work within the constraints of existing laws to restructure themselves as for-benefit entities, or they could create, under federal law, a new for-benefit AMC model, allowing for the orderly conversion of not-for-profit AMCs. Essential components of a for-benefit AMC include a social purpose, access to multiple forms of capital, the use of earnings to support its purpose, transparency, aligned compensation, and tax exemptions. Restructuring an AMC as a for-benefit entity enables it to both advance shareholder value and further the public good.

    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 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.

    Full Text Available Abstract Background Many patients experience difficulties in following treatment recommendations. This study's objective is to identify nonadherence risk profiles regarding medication (antidepressants, antihypertensives, and oral hypoglycemics from a combination of patients' socio-demographic characteristics, morbidity presented within general practice and medication characteristics. An additional objective is to explore differences in nonadherence among patients from different general practices. Methods Data were obtained by linkage of a Dutch general practice registration database to a dispensing registration database from the year 2001. Subjects included in the analyses were users of antidepressants (n = 4,877, antihypertensives (n = 14,219, or oral hypoglycemics (n = 2,428 and their GPs. Outcome variables were: 1 early dropout i.e., a maximum of two prescriptions and 2 refill nonadherence (in patients with 3+ prescriptions; refill adherence Results Both early dropout and refill nonadherence were highest for antidepressants, followed by antihypertensives. Risk factors appeared medication specific and included: 1 non-western immigrants being more vulnerable for nonadherence to antihypertensives and antidepressants; 2 type of medication influencing nonadherence in both antihypertensives and antidepressants, 3 GP consultations contributing positively to adherence to antihypertensives and 4 somatic co-morbidity influencing adherence to antidepressants negatively. There was a considerable range between general practices in the proportion of patients who were nonadherent. Conclusion No clear risk profiles for nonadherence could be constructed. Characteristics that are correlated with nonadherence vary across different types of medication. Moreover, both patient and prescriber influence adherence. Especially non-western immigrants need more attention with regard to nonadherence, for example by better monitoring or communication. Since it is not

    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.

    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. 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. 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 advertisements (2.7%) promoted the assessment of cardiovascular risk

    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

    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.

    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

    Background-Blood pressure (BP) is recognized as a major risk factor for white matter lesions (WMLs), but longitudinal data are scarce, and there is insufficient evidence for the benefit of antihypertensive therapy on WML progression. We studied the relationship between BP change and WML volume progression over time in a sample of 1319 elderly individuals who had 2 cerebral magnetic resonance imaging examinations 4 years apart. We also examined the impact of antihypertensive treatment on WML progression. Methods and Results-Subjects were participants from the Three-City (3C)-Dijon Magnetic Resonance Imaging Study, a prospective population-based cohort of elderly ≥65 years of age. WML volumes and their progression were estimated with the use of a fully automatic procedure. We performed ANCOVA models first to assess the association between BP change and WML progression and second to estimate the relation between antihypertensive treatment and WML load progression. Baseline and change in BP were significant predictors of higher WML progression over time after controlling for potential confounders. Among subjects with high SBP (160 mm Hg) at baseline not treated by antihypertensive medication, antihypertensive treatment started within 2 years was related to a smaller increase in WML volume at a 4-year follow-up (0.24 cm 3 ; SE0.44 cm 3 ) than no hypertensive treatment (1.60 cm 3 ; SE0.26 cm 3 ; P0.0008) on multivariable modeling. Conclusions-Our findings reinforce the hypothesis that hypertension is a strong predictor of WML and that adequate treatment may reduce the course of WML progression. Because WMLs are linked to both dementia and stroke risks, these results could have implications for future preventive trials. (authors)

    Full Text Available Out of a total of 1147 patients on antihypertensive drugs, 23 (2.04% developed adverse cutaneous drug reactions (ACDR. The commonest antihypertensive drug group causing ACDR was beta-blockers of which atenolol was the commonest culprit. The second most common group was calcium channel blockers with amlodipine as the commonest offender. The most common patterns of ACDR observed included urticaria followed by lichenoid drug eruption (LDE. We noted 2 new patterns of reactions; (i one patient developed brownish blue pigmentation of nails while on atenolol for 3 years, which resolved in 4 months after withdrawal and (ii another patient on amlodipine for 8 years developed Schamberg′s like purpuric pigmentation, which resolved on withdrawal of drug within 3 months. These findings have not been reported in the literature earlier. This study is presented for paucity of Indian data on ACDR due to antihypertensive drugs, and remarkable advancement in area of cardiovascular and antihypertensive pharmacology and a large number of population taking antihypertensive drugs.

    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.

    This study evaluates the effects of the medical clerks introduced to reduce physicians' workloads in outpatient clinics by assisting with their documentation processes (e.g., the production of electronic medical records (EMRs)). The volume of information written in narrative text in EMRs from 2007 (pre-introduction of medical clerks) to 2012 (post-introduction) was measured by counting Japanese characters. The total number of medical records for analysis was 1,577. The average number of characters in EMRs increased from before the introduction of medical clerks to afterwards regardless of the types of documents (subjective or objective data) or visits (first or second visits). We conclude that introducing medical clerks improves the quantity of outpatients' medical records and that such a character-counting method is useful for evaluating the benefit of the introduction of medical clerks to assist physicians.

    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

    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.

    Online formative assessments have a sound theoretical basis, and are prevalent and popular in higher education settings, but data to establish their educational benefits are lacking. This study attempts to determine whether participation and performance in integrated online formative assessments in the biomedical sciences has measurable effects on learning by junior medical students. Students enrolled in Phase 1 (Years 1 and 2) of an undergraduate Medicine program were studied over two consecutive years, 2006 and 2007. In seven consecutive courses, end-of-course (EOC) summative examination marks were analysed with respect to the effect of participation and performance in voluntary online formative assessments. Online evaluation surveys were utilized to gather students' perceptions regarding online formative assessments. Students rated online assessments highly on all measures. Participation in formative assessments had a statistically significant positive relationship with EOC marks in all courses. The mean difference in EOC marks for those who participated in formative assessments ranged from 6.3% (95% confidence intervals 1.6 to 11.0; p = 0.009) in Course 5 to 3.2% (0.2 to 6.2; p = 0.037) in Course 2. For all courses, performance in formative assessments correlated significantly with EOC marks (p course). The variance in EOC marks that could be explained by performance in the formative assessments ranged from 21.8% in Course 6 to 4.1% in Course 7. The results support the contention that well designed formative assessments can have significant positive effects on learning. There is untapped potential for use of formative assessments to assist learning by medical students and postgraduate medical trainees.

    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.

    In septic shock, chronic antihypertensive medications are held acutely. Vasopressors are often required to maintain blood pressure. The effect of chronic exposure to antihypertensive therapies on vasopressor dosing in septic shock is not known. To determine the effects of chronic exposure to antihypertensive therapies, specifically β-blockers and angiotensin-converting enzyme (ACE) inhibitors, on cumulative vasopressor dosing in septic shock. This was a retrospective cohort review, with data collected from routine care. Patients admitted to the medical intensive care unit with septic shock and vasopressor use were included and divided into 4 groups based on chronic medication use: (1) no β-blocker or ACE inhibitor, (2) β-blocker only, (3) ACE inhibitor only, and (4) β-blocker and ACE inhibitor. Cumulative vasopressor dose at 48 hours was assessed. Demographics, comorbid conditions, suspected site of infection, disease severity, mortality, and concomitant therapies were evaluated between groups. A total of 133 patients with septic shock treated with vasopressors were included. No difference in cumulative vasopressor dose at 48 hours was detected between the 4 groups, respectively (median norepinephrine milligram equivalents [interquartile range (IQR)]: no β-blocker or ACE inhibitor, 13.7 mg [6.0-35.7]; β-blocker only, 13.1 mg [5.4-23.9]; ACE inhibitor only, 13.2 mg [1.2-36.7]; β-blocker and ACE inhibitor, 11.3 mg [4.7-42.9]; P = 0.669). Total time on vasopressors differed between groups (median hours [IQR]: no β-blocker or ACE inhibitor, 30h [17-60]; β-blocker only, 24h [10-69]; ACE inhibitor only, 19h [6-25]; β-blocker and ACE inhibitor, 30h [15-58]; P = 0.031). Comorbid conditions, suspected infection sites, disease severity, mortality, and concomitant therapies were similar. Chronic β-blocker, ACE inhibitor use, or the combination of both did not affect cumulative vasopressor dose at 48 hours in septic shock. However, prior-to-admission medications may

    Discontinuation of antihypertensive treatment is known to be different for different classes of antihypertensive drugs. No information is available on whether this phenomenon differs for drugs belonging to the same class. This is clinically relevant because treatment discontinuation is mainly responsible for poor blood pressure control in the antihypertensive population. We studied a large (n=131,472) cohort of patients aged 40-80 years who lived in Lombardy (Italy) and received their first antihypertensive drug prescription during 2005. Discontinuation was defined by the absence of any antihypertensive drug prescription during the 90-day period following the end of the latest prescription. Class-related and drug-related discontinuation rates were standardized according to the demographic and therapeutic structure of the entire cohort and expressed as number of patients who experienced discontinuation every 100 person-months. Standardized rates of discontinuation ranged from 6.2 to 24.4 events every 100 person-months for patients who started monotherapy with an angiotensin receptor antagonist and a diuretic, respectively. However, there was a significant heterogeneity between treatment discontinuation rates within each class and the heterogeneity differed between classes. The highest discontinuation rate was 13.9-fold for channel blockers, but only 1.7-fold for angiotensin receptor antagonists. Within this class, losartan showed a discontinuation rate significantly greater than that of the other angiotensin receptor antagonists whose discontinuation rate was similar. A significant heterogeneity also characterized initial treatment with fixed-dose combinations of different angiotensin-converting enzyme inhibitors or angiotensin receptor antagonists with a diuretic. Comparison of treatment discontinuation between antihypertensive drug classes masks the fact that this phenomenon is heterogeneous within any given class. This is relevant to calculations of the cost-benefit

    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

    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.

    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.

    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.

    Sickness absence in Sweden is high, particularly in young women and the reasons are unclear. Many Swedish women combine parenthood and work and are facing demands that may contribute to impaired health and well-being. We compared mothers and women without children under different conditions, assuming increased sickness absence in mothers, due to time-based stress and psychological strain. All women born in 1960-79 (1.2 million) were followed from 1993 to 2003. Information on children in the home for each year was related to medically certified sickness absence with insurance benefits the year after. We used age and time-stratified proportional hazard regression models accounting for the individual's changes on study variables over time. Data were retrieved from national administrative registers. Sickness absence was higher in mothers than in women without children, the relative risks decreased by age, with no effect after the age of 35 years. An effect appeared in lonely women irrespective of age, while in cohabiting women only for the ages 20-25 years. Mothers showed increased sickness absence in all subgroups of country of birth, education, income, sector of employment and place of residence. The relation between number of children and sickness absence was nonlinear, with the highest relative risks for mothers of one child. The upward trend of sickness absence at the end of 1990s was steeper for mothers compared to women without children. Despite the well-developed social security system and child care services in Sweden, parenthood predicts increased sickness absence, particularly in young and in lone women.

    Machiavellianism is a word synonymous with the phrase "the end justifies the means", and in this article we have coined the term Medical Machiavellianism to describe the 'cruel-to-be-kind' administration of toxic chemotherapeutic agents in apparent violation of the precept first do no harm, while acknowledging the 'dirty hands' dilemma of having to decide between and choose the lesser of two evils in the setting of advanced cancer--i.e. to treat or not to treat. The perception that 'targeted' therapies are relatively non-toxic and therefore respect the Hippocratic First Commandment by virtue of their narrow selectivity is belied by their often inherent promiscuity, addressing multiple targets either inadvertently or deliberately, which may result in multiple side effects. The remarkable success of immunotherapy may have taken the bloom off the 'targeted agent' rose, however due to a lack of other approved treatment alternatives the toxicity of these agents may be overlooked or, at least, undervalued, especially given that the official measure of treatment success in oncology is overall survival (OS), not quality-of-life improvements. By analogy with the MACH-IV personality survey (1970), [1] which measures high and low Machiavellian orientation, we have defined in this article a rudimentary MACH scale for selected targeted chemotherapies, based on the means-to-ends ratio of toxicity and benefit. It is our hope that this comparison between targeted agents will itself function as a means to an end--to help oncologists strike the right balance between efficacy, toxicity and quality of life in the management of their patients.

    Public safety can be enhanced through the development of a comprehensive medical device risk management. This can be accomplished through case studies using a framework that incorporates cost-benefit analysis in the evaluation of risk management attributes. This paper presents a framework for evaluating the risk management system for regulatory Class III medical devices. The framework consists of the following sixteen attributes of a comprehensive medical device risk management system: fault/failure analysis, premarket testing/clinical trials, post-approval studies, manufacturer sponsored hospital studies, product labeling, establishment inspections, problem reporting program, mandatory hospital reporting, medical literature surveillance, device/patient registries, device performance monitoring, returned product analysis, autopsy program, emergency treatment funds/interim compensation, product liability, and alternative compensation mechanisms. Review of performance histories for several medical devices can reveal the value of information for many attributes, and also the inter-dependencies of the attributes in generating risk information flow. Such an information flow network is presented as a starting point for enhancing medical device risk management by focusing on attributes with high net benefit values and potential to spur information dissemination.

    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.

    Arterial hypertension is the most common modifiable risk factor for cerebrovascular and cardiovascular morbidity and mortality in old age. The prevention of cognitive brain disorders is also a therapeutic goal of long-term treatment of hypertension. Older patients also have a higher risk of developing cardiovascular diseases and therefore benefit from a relatively moderate reduction in blood pressure. With respect to the high prevalence of hypertension in old age and the increasing incidence with time, the therapy of hypertension is becoming increasingly more important to achieve an improved prognosis for patients along with a reduction of costs. The accurate blood pressure measurement for elderly patients includes repeated measurements while standing and sitting. Additionally, the measurements should also be conducted by the patient or by a family member. The most accurate method for assessing the daily blood pressure level, e.g. practice hypertension, non-dipping and intermittent hypertension, is the 24-h blood pressure measurement by ambulatory blood pressure monitoring (ABPM). General measures and lifestyle interventions are effective for reducing blood pressure of elderly patients with hypertension and a low salt diet is scientifically proven to be superior. The same drugs used for young people are also recommended for older patients and most give preference to diuretics, renin-angiotensin-aldosterone system (RAAS) inhibitors and calcium antagonists. The target blood pressure in elderly patients is repeatedly the focus of scientific discussions. The current recommendations are presented in the text and the characteristics which must be particularly considered in the therapy of elderly patients are presented in detail.

    Background In Germany, educational deficits or potential benefits involved in global health education have not been analysed till now. Objective 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. Methods 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. Results 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 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. Conclusion 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. Developing concerted educational interventions aimed at fostering students' engagement with SDH could make full use of synergy effects inherent

    There are limitations of the use of several classes of antihypertensive drugs in patients after kidney transplantation (KTx), as well as contradictory opinions on their effects on progression of graft dysfunction. In this study we assessed the prevalence of arterial hypertension (HA) and the antihypertensive agents used by the patients long after KTx. This retrospective evaluation of the number and classes of antihypertensive drugs was based on medical records of 348 patients (140 F, 208 M; mean age 49 ± 13 years) late after KTx (mean time after KTx 78 ± 43 months). The data were related to graft function. Ninety-three percent of patients after KTx required antihypertensive therapy. Only 8.7% were treated with 1 agent (mean eGFR 65.1 ± 27.4 ml/min), 26.3% received 2 drugs (eGFR 60.0 ± 25.8 ml/min), 34.2% received 3 drugs (eGFR 55.5 ± 23.4 ml/min), 20.1% received 4 drugs (eGFR 54.9 ± 24.9 ml/min), and 10.5% received ≥ 5 drugs (eGFR 45.9 ± 22.0 ml/min). The number of antihypertensive medications increased along with the deterioration of graft function. Dihydropyridine calcium antagonists (CCB) were the most common class of drugs recommended to the patients after KTx (81%), followed by β-adrenergic antagonists (74.4%); α-antagonists (40.2%), angiotensin-converting enzyme inhibitors (38.7%), diuretics (34.1%), clonidine (17.8%) and angiotensin II receptor blockers (9.5%). HA is highly prevalent in KTx patients. Multidrug therapy is usually required for the treatment of HA in this population. Dihydropyridine CCB is the most common class of antihypertensive drugs used by them. Graft function is a determining factor in the number of antihypertensive agents.

    Enrollment in high-deductible health plans is increasing out-of-pocket spending. But innovative plans that pair deductibles with value-based insurance designs can help preserve low-cost access to high-value treatments for patients by aligning coverage with clinical value. Among adults in high-deductible health plans who were prescribed medications for chronic conditions, we examined what impact a value-based pharmacy benefit that offered free chronic disease medications had on medication adherence. Overall, we found that the value-based plan offset reductions in medication adherence associated with switching to a deductible plan. The value-based plan appeared particularly beneficial for patients who started with low levels of medication adherence. Patients with additional clinical complexity or vulnerable populations living in neighborhoods with lower socioeconomic status, however, did not show adherence improvements and might not be taking advantage of value-based insurance design provisions. Additional efforts may be needed to educate patients about their nuanced benefit plans to help overcome initial confusion about these complex plans.

    Implementation of systems to support health information sharing has lagged other areas of healthcare IT, yet offers a strong possibility for benefit.  Clinical acceptance is a key limiting factor in health IT adoption. To assess the benefits and challenges experienced by clinicians using a custom-developed health information exchange system, and to show how perceptions of benefits and challenges influence perceptions of productivity and care-related outcomes. We used a mixed methods design with two phases. First, we conducted interviews with stakeholders who were familiar with the health information exchange system to inform the development of a measure of benefits and challenges of the use of this system. Second, using this measure we conducted a survey of current and former users of the health information exchange system using a modified Dillman method. 105 current and former users completed the survey. The results showed information quality, ease of completing tasks and clinical process improvement as key benefits that reduced workload and improved patient care.  Challenges related to system reliability, quality of reports and service quality increased workload and decreased impact on care, though the effect of the challenges was smaller than that of the benefits.  Even very limited health information exchange capabilities can improve outcomes for primary care users.  Improving perceptions of benefits may be even more important the removing challenges to use, though it is likely that a threshold of quality must be achieved for this to be true.

  9. New-onset diabetes and antihypertensive treatment

    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

  10. The potential of medical abortion to reduce maternal mortality in Africa: what benefits for Tanzania and Ethiopia?

    Full Text Available Unsafe abortion is estimated to account for 13% of maternal mortality globally. Medical abortion is a safe alternative.By estimating mortality risks for unsafe and medical abortion and childbirth for Tanzania and Ethiopia, we modelled changes in maternal mortality that are achievable if unsafe abortion were replaced by medical abortion. We selected Ethiopia and Tanzania because of their high maternal mortality ratios (MMRatios and contrasting situations regarding health care provision and abortion legislation. We focused on misoprostol-only regimens due to the drug's low cost and accessibility. We included the impact of medical abortion on women who would otherwise choose unsafe abortion and on women with unwanted/mistimed pregnancies who would otherwise carry to term.Thousands of lives could be saved each year in each country by implementing medical abortion using misoprostol (2122 in Tanzania and 2551 in Ethiopia assuming coverage equals family planning services levels: 56% for Tanzania, 31% for Ethiopia. Changes in MMRatios would be less pronounced because the intervention would also affect national birth rates.This is the first analysis of impact of medical abortion provision which takes into account additional potential users other than those currently using unsafe abortion. Thousands of women's lives could be saved, but this may not be reflected in as substantial changes in MMRatios because of medical abortion's demographic impact. Therefore policy makers must be aware of the inability of some traditional measures of maternal mortality to detect the real benefits offered by such an intervention.

    Drug related problems have a significant clinical and economic burden on patients and the healthcare system. Medication review with follow-up (MRF) is a professional pharmacy service aimed at improving patient's health outcomes through an optimization of the medication. To ascertain the economic impact of the MRF service provided in community pharmacies to aged polypharmacy patients comparing MRF with usual care, by undertaking a cost analysis and a cost-benefit analysis. The economic evaluation was based on a cluster randomized controlled trial. Patients in the intervention group (IG) received the MRF service and the comparison group (CG) received usual care. The analysis was conducted from the national health system (NHS) perspective over 6 months. Direct medical costs were included and expressed in euros at 2014 prices. Health benefits were estimated by assigning a monetary value to the quality-adjusted life years. One-way deterministic sensitivity analysis was undertaken in order to analyse the uncertainty. The analysis included 1403 patients (IG: n = 688 vs CG: n = 715). The cost analysis showed that the MRF saved 97 € per patient in 6 months. Extrapolating data to 1 year and assuming a fee for service of 22 € per patient-month, the estimated savings were 273 € per patient-year. The cost-benefit ratio revealed that for every 1 € invested in MRF, a benefit of 3.3 € to 6.2 € was obtained. The MRF provided health benefits to patients and substantial cost savings to the NHS. Investment in this service would represent an efficient use of healthcare resources.

    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.

    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.

    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. Developing concerted educational interventions aimed at fostering students' engagement with SDH

    To identify the frequency of medical students interpreting in healthcare settings and to explore the issues related to the use of non-professional interpreters. All 4th and 5th year University of Otago medical students were surveyed to identify bilingual medical students who have interpreted for patients. Students and key informants were interviewed and audiotaped. Of the 102 bilingual students identified, 59 interpreted for patients. We analysed 39 student interviews. Most reported a 'good' interpreting experience and thought student interpreting was 'a good idea', but some encountered 'bad' experiences. Stakeholders (professional interpreters, DHB policy staff, and clinicians who use interpreters) thought students should not interpret. Issues explored were: student comfort, clinician's choice, the interpreter's role, cultural competency, awareness, and provision of interpreting services. A considerable proportion of bilingual clinical medical students have interpreted for patients contrary to Capital and Coast District Health Board policy and professional interpreter recommendations. In conjunction with published literature and after consulting with interpreter trainers, we have developed a document which canvasses the issues involved and proposed practical guidelines, to better prepare healthcare professionals and non-professional interpreters for interpreting situations. More research is required to find out why clinicians are asking medical students and others to interpret rather than engaging professional interpreters.

    BACKGROUND The explosive increase in medical literature has changed therapeutic strategies, but it is challenging for physicians to keep up-to-date on the medical literature. Scientific literature data mining on a large-scale of can be used to refresh physician knowledge and better improve the quality of disease treatment. MATERIAL AND METHODS This paper reports on a reformulated version of a data mining method called MedRank, which is a network-based algorithm that ranks therapy for a target disease based on the MEDLINE literature database. MedRank algorithm input for this study was a clear definition of the disease model; the algorithm output was the accurate recommendation of antihypertensive drugs. Hypertension with diabetes mellitus was chosen as the input disease model. The ranking output of antihypertensive drugs are based on the Joint National Committee (JNC) guidelines, one through eight, and the publication dates, ≤1977, ≤1980, ≤1984, ≤1988, ≤1993, ≤1997, ≤2003, and ≤2013. The McNemar's test was used to evaluate the efficacy of MedRank based on specific JNC guidelines. RESULTS The ranking order of antihypertensive drugs changed with the date of the published literature, and the MedRank algorithm drug recommendations had excellent consistency with the JNC guidelines in 2013 (P=1.00 from McNemar's test, Kappa=0.78, P=1.00). Moreover, the Kappa index increased over time. Sensitivity was better than specificity for MedRank; in addition, sensitivity was maintained at a high level, and specificity increased from 1997 to 2013. CONCLUSIONS The use of MedRank in ranking medical literature on hypertension with diabetes mellitus in our study suggests possible application in clinical practice; it is a potential method for supporting antihypertensive drug-prescription decisions.

    Universities are increasingly organizing international exchange programs to meet the requirements of growing globalisation in the field of health care. Analyses based on the programs' fundamental theoretical background are needed to confirm the learning value for participants. This study investigated the extent of sociocultural learning in an exchange program and how sociocultural learning affects the acquisition of domain-specific competencies. Sociocultural learning theories were applied to study the learning effect for German medical students from the LMU Munich, Munich, Germany, of participation in the medical exchange program with Jimma University, Jimma, Ethiopia. First, we performed a qualitative study consisting of interviews with five of the first program participants. The results were used to develop a questionnaire for the subsequent, quantitative study, in which 29 program participants and 23 matched controls performed self-assessments of competencies as defined in the Tuning Project for Health Professionals. The two interrelated studies were combined to answer three different research questions. The participants rated their competence significantly higher than the control group in the fields of doctor-patient relationships and communication in a medical context. Participant responses in the two interrelated studies supported the link between the findings and the suggested theoretical background. Overall, we found that the exchange program affected the areas of doctor-patient relationships and effective communication in a medical context. Vygotsky's sociocultural learning theory contributed to explaining the learning mechanisms of the exchange program.

    To evaluate the impact of comprehensive geriatric assessment and management of high-risk elders in a medical short stay unit located in the emergency department of a general hospital. We performed a descriptive, prospective study of patients admitted to the medical short stay unit for geriatric patients of the emergency department in 2006. A total of 749 patients were evaluated, with a mean (standard deviation) stay in the unit of 37 (16) h. The mean age was 86 (7) years; 57% were women, and 50% had moderate-severe physical impairment and dementia. Thirty-five percent lived in a nursing home. The most frequent reason for admission was exacerbation of chronic cardiopulmonary disease. Multiple geriatric syndromes were identified. The most frequent were immobility, pressure sores and behavioral disorders related to dementia. Seventy percent of the patients were discharged to home after being stabilized and were followed-up by the geriatric clinic and day hospital (39%), the home care medical team (11%), or the nursing home or primary care physician (20%). During the month after discharge, 17% were readmitted and 7.7% died, especially patients with more advanced age or functional impairment. After the unit was opened, admissions to the acute geriatric unit fell by 18.2%. Medical short stay units for geriatric patients in emergency departments may be useful for geriatric assessment and treatment of exacerbations of chronic diseases. These units can help to reduce the number of admissions and optimize the care provided in other ambulatory and domiciliary geriatric settings.

  11. AWARENESS OF MEDICAL SPECIALISTS AND PATIENTS IN BULGARIA OF ETHICS COMMITTEES AND THE BENEFITS OF THEIR WORK

    Directory of Open Access Journals (Sweden)

    2018-02-01

    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.

    In India, there has been little effort to teach medical students about public health research. Few medical institutions in India and nearby Nepal formally offer exposure to field surveys or projects to medical undergraduates as a part of their training in community medicine. Little is known about the effect of such activity on students or how they apply what they learn. We implemented a systematic, hands-on experience in the public health research process with medical undergraduates in Puducherry, India to evaluate its effect on students. Two groups, each with 30 third-semester (second year) medical undergraduates, participated in a 15-day, two and one-half hours per day course on the public health research process. At the end of course, a retrospective post-then-pre self-assessment of students skills was obtained. One year later, we resurveyed students with open-ended questions to assess their impressions of what they had gained from learning about the field survey process. Out of the 60 students, 55 (91.6%) provided complete responses for analysis. The mean post-exposure Likert scores of students self-perceived skills and knowledge were significantly higher than their retrospective assessments of themselves prior to the course in areas such as being aware of the public health research process, their skills in interviewing and communicating with local villagers, and ability to collect, enter via computer and present gathered information (p undergraduates to the survey research process appears to help them be better clinicians, who are able to understand and use field level data.

    Aerobic exercise reduces blood pressure (BP) on average 5-7 mmHg among those with hypertension; limited evidence suggests similar or even greater BP benefits may result from isometric handgrip (IHG) resistance exercise. We conducted a randomized controlled trial investigating the antihypertensive effects of an acute bout of aerobic compared with IHG exercise in the same individuals. Middle-aged adults (n = 27) with prehypertension and obesity randomly completed three experiments: aerobic (60% peak oxygen uptake, 30 min); IHG (30% maximum voluntary contraction, 4 × 2 min bilateral); and nonexercise control. Study participants were assessed for carotid-femoral pulse wave velocity pre and post exercise, and left the laboratory wearing an ambulatory BP monitor. SBP and DBP were lower after aerobic versus IHG (4.8 ± 1.8/3.1 ± 1.3 mmHg, P = 0.01/0.04) and control (5.6 ± 1.8/3.6 ± 1.3 mmHg, P = 0.02/0.04) over the awake hours, with no difference between IHG versus control (P = 0.80/0.83). Pulse wave velocity changes following acute exercise did not differ by modality (aerobic increased 0.01 ± 0.21 ms, IHG decreased 0.06 ± 0.15 ms, control increased 0.25 ± 0.17 ms, P > 0.05). A subset of participants then completed either 8 weeks of aerobic or IHG training. Awake SBP was lower after versus before aerobic training (7.6 ± 3.1 mmHg, P = 0.02), whereas sleep DBP was higher after IHG training (7.7 ± 2.3 mmHg, P = 0.02). Our findings did not support IHG as antihypertensive therapy but that aerobic exercise should continue to be recommended as the primary exercise modality for its immediate and sustained BP benefits.

    A study was planned to explore and evaluate the role of senior peers in the learning process of their juniors during a Research Methodology workshop, and to assess educational advantages for seniors in leading roles. Twenty medical students participated with 15 juniors (1st to 3rd year) and 5 seniors (final/fourth year) divided into 5 groups with one senior student each at Foundation University Medical College, Islamabad, Pakistan. The seniors supervised and engaged the groups to develop research questions, formulate objectives, review literature, outline study designs, develop study tools/questionnaire and finally shape their projects in synopsis. Overall advantages to both juniors and seniors through this peer-assisted learning model were assessed by feedback proformas with open and closed-ended questions. Senior peers' facilitation was effective in the learning process of junior peers. Senior peers also gained academic benefit by exercising their leadership qualities through teaching and maintaining group dynamics.

    This paper review the historical trends and current situation in doses to patients from diagnostic radiology, to investigate whether the optimisation 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. The overall conclusion is that the control of patient doses from diagnostic radiology is reasonable - but iT could be better. (55 refs.)

    For millions of injured and disabled people around the world, the treatment brings a new quality of life. Called tissue grafting or transplantation, it relies on the use of sterilized bone, skin, and other tissues to heal serious injuries, wounds, and sickness. Prime beneficiaries include severe burn victims, and men, women, and children suffering from crippling diseases, birth defects, and blindness. Long applied in plastic and orthopaedic surgery, tissue grafting once relied only on using a patient's own tissues, known as an autograft. But now tissues from human or animal donors (allograft) are used for transplantation. This new form of tissue grafting has made big strides over the past decade. An expanding number of facilities today prepare the valuable tissues to the high-quality standards demanded in medical care. Dozens of such new tissue banks have opened in Asia, Latin America, Europe, and North America. A productive channel of progress has been an IAEA-supported technical cooperation programme. Through it, experts have worked together behind the scenes to help national health authorities establish tissue banks, train associated staff, and develop standards and regulatory guides. The IAEA accordingly has gained more experience and success than any other international organization in supporting the establishment of tissue banks for medical use in developing countries. Increasingly for quality and cost reasons, the technology of irradiation is used to sterilize tissues for medical care. The IAEA, through its technical cooperation channels, assists national atomic energy authorities to safely and productively employ radiation technology. An interregional programme on radiation and tissue banking, initiated over a decade ago, today extends to 30 countries

    Task and error analysis research was performed to identify: a) the process for healthcare organisations in managing healthcare for patients with mental illness or substance abuse; b) how the process can be enhanced and; c) if electronic medical records (EMRs) have a role in this process from a business and safety perspective. The research question is if EMRs have a role in enhancing the healthcare for patients with mental illness or substance abuse. A discussion on the business of EMRs is addressed to understand the balancing act between the safety and business aspects of an EMR.

    Many of the social determinants of health are rooted in legal problems. Medical-legal partnerships (MLPs) have the potential to positively change clinical systems. This change can be accomplished by integrating legal staff into health care clinics to educate staff and residents on social determinants of health and their legal origins. When the MLP team works directly with patients to identify and address legal needs that improve health outcomes, and incorporate legal insights and solutions into health care practice where the patient population is overwhelmingly impacted by social conditions, outcomes are beneficial to children and families.

    Limited studies have evaluated the medication-taking behavior in very elderly hypertensive patients. The aim of this study was to evaluate the persistence and adherence with antihypertensive agents in treatment-naïve patients, along with other related factors, according to age. Adult (19-64 years), elderly (65-79 years), and very elderly (≥80 years) uncomplicated hypertensive patients starting antihypertensive monotherapy were identified from the National Health Insurance claims database. The first-year treatment persistence and adherence rates measured using the medication possession ratio were assessed and compared in these three age cohorts. After propensity score matching, three age cohorts with 6689 patients each were assembled from 228,925 uncomplicated hypertensive patients who began antihypertensive monotherapy in 2012. The treatment persistence and adherence rates over the first year were the lowest in the very elderly (59.5% and 62.8%, respectively) and highest in the elderly (65.2% and 67.9%, respectively) patients among the three age cohorts (p elderly (adjusted hazard ratio, 1.20; 95% confidence interval, 1.13-1.27) compared with the elderly. Having more comorbidities, being a beneficiary of medical aid, and having a diagnosis of dementia were unique positive predictors for treatment persistence in the very elderly, along with common predictors such as female sex, dyslipidemia, and an initially chosen antihypertensive therapeutic class other than beta blockers and thiazide diuretics. Very elderly patients were less likely to continue antihypertensive therapy over the first year compared with their younger counterparts. Our findings suggest that a low comorbidity index and lack of medical aid support negatively affect the treatment persistence in this population.

    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.

    Aging is associated with arterial stiffening and subsequent acceleration of pulse wave movement. Traditional cardiovascular risk factors such as hypertension and dyslipidemia are associated with increased arterial stiffness, a 'premature' arterial aging. Antihypertensive drugs exhibit beneficial effects on arterial stiffness, both at the central and peripheral level, and these effects are mainly attributed to blood pressure reduction per se. However, additional benefits of the renin-angiotensin system inhibitors have been recently suggested. Furthermore, a disparity in the effects of beta-blockers on arterial stiffness between conventional and vasodilatory agents has also been suggested. Statin treatment is an essential element of cardiovascular therapy and statins are frequently administered by patients with cardiovascular risk factors or established cardiovascular disease. The effects of statins on arterial stiffness are not yet well established. Moreover, the effects of combining statins with antihypertensive drugs or other strategies to attenuate arterial aging are not adequately studied. The aim of the current review is to present the effects of available therapeutic strategies on arterial stiffness with special emphasis on hypolipidemic and antihypertensive drugs, critically evaluate available information and provide future perspectives in this field.

    To study the impact of primary care oriented outpatient benefits package design of outpatient services coverage and ladder reimbursement of county, town and village levels in the new rural cooperative medical system (NRCMs) on hypertension outpatient services utilization. The panel data of treatment and control groups in 2009 and 2011 before and after the policy reform were drawn from the household survey data of the innovative payment system project. The difference in difference (DID) method was used for data analysis. The outcome indicators included the utilization of outpatient services of patients with self-reported hypertension and their main treatment locations. The primary care oriented outpatient benefit package design in the NRCMs reduced the probability of no treatment in the latest three months of hypertension by 10.2 percent points. Meanwhile, it increased the probability of choosing village clinic as the preferred location by 15.7 percent points. Primary care oriented outpatient benefits package design lead patients with hypertension to use the nearest outpatient services at low risk of disease.

    Medical Qigong (MQ) is a mind-body exercise that includes movement and meditation and is beneficial in reducing high blood pressure, high cholesterol, anxiety, stress, pain, and incidence of falls. The purpose of the current study was to determine whether patients with cancer and survivors who participated in an MQ class experienced a change in fatigue, depression, and sleep from a preintervention evaluation to a postintervention evaluation. Participants were patients diagnosed with cancer who participated in MQ classes. Some were actively undergoing cancer treatment (e.g., surgery, hormone therapy, radiation therapy, chemotherapy) and some were receiving no treatment. Patients diagnosed with cancer and enrolled in an MQ class were invited to participate. A packet of surveys was completed before the first class and before the final class. Scores showed a reduced depression score after completing the five-week MQ course. Those findings indicate that MQ is helpful in reducing some of the problems associated with cancer and cancer treatment.

    As more individuals turn to the Internet for health-related information and technology increases the availability and use of implantable medical devices (IMDs), the websites marketing these devices will increase. Healthy People 2020 mandates increased understandability and usability of health-related websites. This project used social cognitive theory (SCT) and health literacy constructs from the Institute of Medicine and National Institutes of Health to analyze eight IMD websites. Despite current recommendations, none of the websites considered for this study offered content of an appropriate reading level in conjunction with the United States average of eighth grade, and 75% of the sites failed to satisfy more than one health literacy construct. Most of the websites lacked many of the SCT constructs. More attention is needed to improve the usability of these and future IMD websites to simultaneously meet the goal of marketing IMDs and the Healthy People 2020 goals to educate patients and promote public health.

  7. From bedside to blackboard: the benefits of teaching molecular biology within a medical context.

    2012-01-01

    Courses in molecular biology are part of practically every degree program in medicine and the life sciences. Historically, many basic discoveries in this field have resulted from investigations by doctors into the nature of diseases. This essay suggests that medical educators deliberately incorporate such material, whether historical or contemporaneous, into their molecular and cell biology courses. An example of such usage, an early report of the detection of bacteriophage activity on pathogenic bacteria, is discussed in detail. Such an approach can potentially narrow the perceived gap between "basic" and "applied" science. As medicine is so intimately and obviously linked with human welfare, this also provides an avenue for educators to discuss issues of scientific integrity and ethics within a "pure science" course.

    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.

    In the multi-site Prescription Opioid Addiction Treatment Study (POATS), conducted within the National Drug Abuse Clinical Trials Network, participants randomly assigned to receive individual drug counseling in addition to buprenorphine-naloxone and medical management did not have superior opioid use outcomes. However, research with other substance-dependent populations shows that subgroups of participants may benefit from a treatment although the entire population does not. We conducted a secondary analysis of POATS data to determine whether a subgroup of participants benefited from drug counseling in addition to buprenorphine-naloxone and medical management, either due to greater problem severity or more exposure to counseling as a result of greater treatment adherence. Problem severity was measured by a history of heroin use, higher Addiction Severity Index drug composite score, and chronic pain. Adequate treatment adherence was defined a priori as attending at least 60% of all offered sessions. Patients who had ever used heroin and received drug counseling were more likely to be successful (i.e., abstinent or nearly abstinent from opioids) than heroin users who received medical management alone, but only if they were adherent to treatment and thus received adequate exposure to counseling (OR=3.7, 95% CI=1.1-11.8, p=0.03). The association between severity and outcome did not vary by treatment condition for chronic pain or ASI drug severity score. These findings emphasize the importance of treatment adherence, and suggest that patients with prescription opioid dependence are a heterogeneous group, with different optimal treatment strategies for different subgroups.

    2013-12-01

    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.

    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.

    Background 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. Objective 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. Methods 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 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

    2017-07-01

    Full Text Available Introduction: 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. Methods: 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. Results: 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. Conclusion: 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

    2009-06-01

    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. Additionally, present knowledge of bioavailability and in-vivo actions of the peptides in fermented milk are discussed.

     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

    Pressure ulcer formation continues to be problematic in acute care settings, especially intensive care units (ICUs). Our institution developed a program for early mobility in the ICU using specially trained nursing aides. The goal was to impact hospital-acquired pressure ulcers incidence as well as factors associated with ICU deconditioning by using specially trained personnel to perform the acute early mobility interventions. A 5-point mobility scale was developed and used to establish a patients' highest level of activity achievable during evaluation. A mobility team was created consisting of skin-care prevention/mobility nurses and a new category of worker called a patient mobility assistant. Each level has a corresponding plan of care (intervention) that was followed and adjusted according to the patient's progress and nursing evaluation. Data collection included the type of interventions at each encounter, mobility and skin assessments, new hospital-acquired pressure ulcer, the current mobility level, Braden score, rate of ventilator-associated pneumonia, ICU length of stay, and hospital readmission. Staff was also surveyed about their attitudes toward mobilization and perception of mobility barriers; a prepilot and a postpilot survey were planned. During the 1-year study interval, 3233 patients were enrolled from the medical intensive care unit (MICU). The 2011 preimplementation MICU hospital-acquired pressure ulcer rate was 9.2%. After 1 year of employing the mobility team, there was a statistically significant decrease in the MICU hospital-acquired pressure ulcer rate to 6.1% (P = .0405). Hospital readmission of MICU patients also significantly decreased from 17.1% to 11.5% (P = .0010). The mean MICU length of stay decreased by 1 day. There were no safety issues directly or indirectly associated with these interventions. Use of this mobility program resulted in a 3% decrease in the most recalcitrant patients in the MICU. This corresponds to a decrease of

    Conventional measurements for assessing psoriasis treatment effects capture improvements at fixed, pre-specified timepoints, failing to account for cumulative clinical benefit over time. Explore the innovative concept of "cumulative clinical benefit" by examining the effect of secukinumab over 52 weeks in moderate-to-severe psoriasis patients. Cumulative clinical benefit was determined as the area-under-the-curve of the percentage of responders over 52 weeks (AUC 0-52 wks ), using pooled data from two phase III trials for patients receiving secukinumab (300 or 150 mg) or etanercept. Normalized cumulative benefit with secukinumab 300 mg, secukinumab 150 mg, and etanercept was 74.2%, 63.2%, and 50.5%, respectively, for PASI 75; 58.0%, 42.5%, and 29.5%, respectively, for PASI 90; 32.3%, 18.8%, and 8.7%, respectively, for PASI 100; and 58.3%, 47.9%, and 38.3%, respectively, for DLQI 0/1. 52-week PASI 75 clinical benefit ratios for secukinumab 300 and 150 mg versus etanercept were 1.47 and 1.25, respectively; the ratio of the two secukinumab doses was 1.17, favoring 300 mg. Post hoc analysis. Cumulative clinical benefit estimated by AUC 0-52 wks is a novel measure for comparing psoriasis treatments. Secukinumab 300 mg provides greater cumulative clinical benefit than secukinumab 150 mg; both provide greater cumulative benefit than etanercept.

    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.

    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

A short-term BP-lowering drug therapy was conducted according to current Brazilian guidelines on hypertension, and basal cytokine levels were measured before and after intervention.Results: Interventions were found to represent current hypertension-management practices in Brazil and corresponded to a significant reduction in systolic and diastolic BP levels in a whole-group analysis, as well as when users and nonusers of the most common therapeutic classes were considered separately. Considering all patients, mean IL-6 and TNF-α levels showed a significant decrease in circulating concentrations (P<0.01 at the endpoint compared with baseline, whereas the mean INF-γ level was not significantly different from baseline values. In separate analyses, only users of antagonists of the renin–angiotensin system and users of diuretics exhibited the same significant treatment-induced reduction in serum IL-6 and TNF-α observed in the whole group.Conclusion: Our data demonstrates that a clinically guided antihypertensive treatment is effective in

    Hematology is difficult for students to learn. A beneficial education method for hematology clerkship training is required to help students develop clinical skills. Foreign medical students often encounter communication issues in China. To address this issue, Chinese post-graduates from our institute are willing to assist with educating foreign students. Therefore, we propose a mixed team-based learning method (MTBL) which might overcome communication problems in hematology clerkship. Twenty-two foreign medical Students attended a 2-week hematology clerkship in Fujian Medical University Union Hospital. Twenty-one foreign African medical students were assigned randomly into two groups. Fourteen foreign African medical students were assigned to MTBL group. Each MTBL team included two foreign African medical students and one Chinese post-graduate. Seven foreign African medical students were assigned to lecture-based learning method (LBL) group, which had a foreign medical classmate from Hong Kong or Chinese intern volunteers to serve as translators. The practice test scores of MTBL were significantly higher than LBL group (p Chinese post-graduates also benefited from this setting, as they found that this interaction improved their communication in the English language. The mixed team-based learning method overcomes communication problems in hematology clerkship. Foreign medical students and Chinese post-graduates alike can benefit from MTBL. © 2016 by The International Union of Biochemistry and Molecular Biology, 45(2):93-96, 2017. © 2016 The International Union of Biochemistry and Molecular Biology.

    content-based access methods into picture archiving and communication systems (PACS) have been created. This article gives an overview of available literature in the field of content-based access to medical image data and on the technologies used in the field. Section 1 gives an introduction into generic content-based image retrieval and the technologies used. Section 2 explains the propositions for the use of image retrieval in medical practice and the various approaches. Example systems and application areas are described. Section 3 describes the techniques used in the implemented systems, their datasets and evaluations. Section 4 identifies possible clinical benefits of image retrieval systems in clinical practice as well as in research and education. New research directions are being defined that can prove to be useful. This article also identifies explanations to some of the outlined problems in the field as it looks like many propositions for systems are made from the medical domain and research prototypes are developed in computer science departments using medical datasets. Still, there are very few systems that seem to be used in clinical practice. It needs to be stated as well that the goal is not, in general, to replace text-based retrieval methods as they exist at the moment but to complement them with visual search tools.

    To assess the efficacy of various classes of antihypertensive drugs in postmenopausal women with hypertension using pulse pressure (PP) as an index. Selected women were required to be naturally menopausal for at least 1 year but not more than 5 years past their menstrual period. Exclusion criteria were a history of preeclampsia or eclampsia, a severe illness such as myocardial infarction or stroke within 6 months, the use of estrogens or progestins within 3 months, proteinuric nephropathy, and surgically induced menopause. There were 114 women who participated in this study after having given informed consent. These women were diagnosed as having hypertension based on an office blood pressure >140/90 mm Hg as well as a self-measured blood pressure at home >130/85 mm Hg. If both levels of blood pressure were not fulfilled, the patients were excluded. All antihypertensive medications were withdrawn 6 weeks before the initiation of the study. The patients were randomly assigned in equal numbers to the following groups: (1) combination therapy with losartan (angiotensin receptor blocker) 50 mg daily + trichlormethiazide (diuretic) 2 mg twice a week, and (2) combination therapy with cilnidipine (calcium channel blocker) 5 mg + arotinolol (αβ-blocker) 10 mg daily. The patients were retrospectively divided into three groups according to their PP at the start of the study: Group I (n = 24), >65 mm Hg; Group II (n = 58), 65-45 mm Hg, and Group III (n = 32), arotinolol resulted in a greater reduction in the systolic blood pressure than the combination therapy with losartan + trichlormethiazide (from 169/88 ± 2/5 to 133/73 ± 2/5 mm Hg vs. from 169/88 ± 2/5 to 149/66 ± 2/5 mm Hg, p < 0.05). On the other hand, in Group III, losartan + trichlormethiazide decreased diastolic as well as systolic blood pressures (from 152/106 ± 2/2 to 123/78 ± 1/1 mm Hg vs. from 149/107 ± 2/2 to 129/84 ± 2/1 mm Hg, p < 0.05). In Group II, there were no differences between the two

    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.

    Explosion injury is very common on the battlefield and is associated with major burn and inhalation injuries and subsequent high mortality and morbidity rates. Here we report six victims who suffered from explosion injuries caused by stun grenade; all were treated with extracorporeal membrane oxygenation (ECMO) as salvage therapy. This study was aimed to evaluate the indications and efficacy of ECMO in acute and critically ill major burn patients. This was a retrospective analysis of six patients from Tri-Service General Hospital, National Defense Medical Center in Taiwan. All suffered from major burns with 89.0±19.1% average of total body surface area over second degree (TBSA; range, 50-99%). ECMO was used due to inhalation injury in five patients and cardiogenic shock in one patient. The average interval to start ECMO was 26.5±19.0h (range, 14-63h). Venoarterial ECMO was used on in four patients due to unstable hemodynamic status, whereas venovenous ECMO was used in two patients for sustained hypoxemia. All patients had rhabdomyolysis with acute renal failure. The average duration of ECMO was 169.6±180.9h (range, 27-401h). All patients developed coagulopathy and needed debridement surgery during ECMO support, and five underwent torso escharotomy due to inspiratory compromise. Only one patient whose second and third degree burns covered 50% TBSA was successfully weaned from ECMO and survived; he was discharged after 221 hospital days. All patients who died had second and third degree burns covering over 90% of their TBSA. Three patients died of multiple organ failure, one died of septic shock, and the other died of cardiogenic shock. Overall survival rate was 16.7%. In acute and critically ill major burn patients, ECMO could be considered as a salvage therapy, particularly in those with inhalation injury and burn-related acute respiratory distress syndrome. However, ECMO does not seem to provide benefits for circulatory support in those with hemodynamic

To evaluate different tactics of initial antihypertensive therapy.Material and Methods. 120 patients with mild-to-moderate arterial hypertension were included and randomized into three groups: “A”, “B”, and “C”. 5 drugs from the main antihypertensive classes were used: indapamide, bisoprolol, amlodipine, fosinopril, and rilmenidine as well as fixed drug combination of fosinopril and hydrochlorothiazide. Patients included in group “A” received initial therapy according to individual leading pathogenic variant of hypertension. Patients from group “B” received standard stepped antihypertensive therapy with gradual dose increase and further addition of second (third drug. Patients in group “C” were immediately administrated fixed drug combination and later added other drugs. Visits were scheduled after 2, 4, 6, 8, 10, etc weeks of treatment up to achievement of target blood pressure (BP.Results. In group “A” 33 patients (82,5% achieved target BP after 6 visits, in group “B” - 37 patients (92,5% after 8 visits and in group “C” - 100% of patents after 6 visits. Thus, in group “C” there was less number of visits and respectively lower number of therapy changes in order to achieve target BP. No significant discrepancies between group “A” and “B” were observed.Conclusion. Tactics of initial antihypertensive therapy with usage of fixed drug combination results in more effective and fast achievement of target BP.

    To evaluate the compliance for antihypertensive treatment and to assess the effects of patient education as tool to improve the compliance in hypertensive patients. We include prospectively all hypertensive patients followed in consultation in the cardiology department of the national police hospital in Ivory Coast. Compliance evaluation was made with the Girerd scale. After evaluation, all the patients benefit from an individual and/or collective education sessions. All the patients were followed and reevaluated after 1 year. We included consecutive 1000 hypertensive patients (mean age 40±20 years, 80 % male). Among these, 50 % have been treated by a single therapy, 30 % by a fixed double therapy and 25 % by a fixed triple combined therapy. At the start of the study, a low compliance is observed in 60 % of patients, 25 % have minimal problems of observance and 15 % are compliant. In 70 %, the low compliance may be explained by misconceptions and is associated with a persistent hypertension. One year after the education program, the compliance is improved: non-compliant patients represent 5 % of the population, 10 % having slight problems on compliance and 85 % have a good compliance. In hypertension, the therapeutic compliance is poor, and associated with various factors. However, patient education improves the therapeutic compliance and this should be systematically proposed in antihypertensive management in Africa. Copyright © 2017 Elsevier Masson SAS.

    Full Text Available 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.

    Drugs with antihypertensive action are frequently used in obstetrics for the treatment of preeclampsia (labetalol) and tocolysis (nifedipine) or for neuroprotection (MgSO4), and may affect the hemodynamics of preterm born neonates. The aim of this study was to assess whether maternal antihypertensive drugs affect multisite oxygenation levels of the neonate. Eighty preterm neonates of ≤32 weeks of gestational age were monitored using near-infrared spectroscopy. Mean cerebral, renal and splanchnic fractional tissue oxygen extractions (cFTOE, rFTOE and sFTOE) were calculated for the first 5 postnatal days. We determined the effect of various maternal antihypertensive drugs on cFTOE and rFTOE using multilevel analysis, and on sFTOE using Kruskal-Wallis and Mann-Whitney U tests. Eleven infants were exposed to labetalol ± MgSO4, 7 to nifedipine ± MgSO4, 20 to MgSO4 only, and 42 to no maternal antihypertensive drugs. The infants exposed to labetalol ± MgSO4 had a lower cFTOE on days 1 (0.14, p = 0.031), 2 (0.13, p = 0.035) and 4 (0.18, p = 0.046) than nonexposed infants on the corresponding days (0.22, 0.20 and 0.24, respectively). On day 2, cFTOE was also lower in infants exposed to nifedipine ± MgSO4 (0.11, p = 0.028) and to MgSO4 only (0.15, p = 0.047). sFTOE was higher in infants exposed to labetalol ± MgSO4 on days 1 (µ = 0.71) and 2 (µ = 0.82) than in nonexposed infants (µ = 0.26, p = 0.04 and µ = 0.55, p = 0.007, respectively). Maternal antihypertensive drugs did not affect rFTOE. Low neonatal cFTOE found with maternal antihypertensive drug exposure may relate to either increased cerebral perfusion or neurologic depression induced by the medication, or preferential brain perfusion associated with preeclampsia placental insufficiency. Concomitantly high sFTOE found with labetalol exposure supports the latter, while renal autoregulation may explain rFTOE stability. © 2016 The Author(s) Published by S. Karger AG, Basel.

    The purpose of this work was to characterize medication errors and adverse drug events intercepted by a system of pediatric clinical pharmacists and to determine whether the addition of a computerized physician order entry system would improve medication safety. The study included 16,938 medication orders for 678 admissions to the pediatric units of a large academic community hospital. Pediatric clinical pharmacists reviewed medication orders and monitored subsequent medication use. Medication errors and adverse drug events were identified by daily review of documentation, voluntary reporting, and solicitation. Each potentially harmful medication error was judged whether or not it was intercepted and, if not, whether it would have been captured by a computerized physician order entry system. Overall, 865 medication errors occurred, corresponding with a rate of 5.2 per 100 medication orders. A near-miss rate of 0.96% and a preventable adverse drug event rate of 0.09% were observed. Overall, 78% of potentially harmful prescribing errors were intercepted; however, none of the potentially harmful errors occurring at administration was intercepted and accounted for 50% of preventable adverse drug events. A computerized physician order entry system could capture additional potentially harmful prescribing and transcription errors (54%-73%) but not administration errors (0% vs 6%). A system of pediatric clinical pharmacists effectively intercepted inpatient prescribing errors but did not capture potentially harmful medication administration errors. The addition of a computerized physician order entry system to pharmacists is unlikely to prevent administration errors, which pose the highest risk of patient injury.

    This study sought to identify factors associated with objectively assessed exercise behavior in Chinese patients with early-stage cancer. 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.

    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.

    To investigate the effect of taurine on hypertension, a rat model of hypertension was produced by administering N-nitro-L-arginine methylester (L-NAME) to reduce the levels of the vasodilator, nitric oxide. At the same time that L-NAME was administered, taurine treated animals received either 1% or 2% taurine in the drinking water. As a control, 1% taurine was added to the water without L-NAME administration in order to investigate the effects of taurine on blood pressure of normal rats. The results showed that taurine increased serum levels of nitric oxide and nitric oxide synthase, inhibited the elevation of blood pressure, interfered with the activity of the renin-angiotensin-aldosterone system and minimized the elevation in serum cytokine, endothelin, neuropeptide Y and thromboxane B2. It also reduced oxygen derived free radical generation, upregulated the antioxidant defenses and inhibited the proliferation of vascular smooth muscle cells. These data indicate that taurine benefits hypertensive rats, with 2% taurine mediating greater improvement than 1% taurine.

    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®.

    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.

    All members of medical staff, including students, were asked to participate in a self-administered questionnaire concerning patterns of mobile phone use and care. Participants' phones were cultured for micro-organisms. Healthcare professionals working in close proximity to sensitive equipment were surveyed concerning adverse events associated with mobile phones. Telephone operators were asked to monitor time elapsed as they attempted to contact medical staff by various methods. Of 266 medical staff and students at the time of the study, 116 completed questionnaires (response rate=44%). Almost all (98%) used mobile phones: 67% used their mobile phones for hospital-related matters; 47% reported using their phone while attending patients. Only 3% reported washing their hands after use and 53% reported never cleaning their phone. In total, 101 mobile phones were cultured for micro-organisms; 45% were culture-positive and 15% grew Gram-negative pathogens. The survey of staff working in close proximity to sensitive equipment revealed only one report of minor interference with life-saving equipment. Telephone operators were able to contact medical staff within 2 min most easily by mobile phone. Mobile phones were used widely by staff and were considered by most participants as a more efficient means of communication. However, microbial contamination is a risk associated with the infrequent cleaning of phones. Hospitals should develop policies to address the hygiene of mobile phones.

    To determine the risks of continuing or ceasing anticoagulant or antiplatelet medications prior to image-guided procedures for spine pain. Systematic review of the literature with comprehensive analysis of the published data. Following a search of the literature for studies pertaining to spine pain interventions in patients on anticoagulant medication, seven reviewers appraised the studies identified and assessed the quality of evidence presented. Evidence was sought regarding risks associated with either continuing or ceasing anticoagulant and antiplatelet medication in patients having image-guided interventional spine procedures. The evidence was evaluated in accordance with the Grades of Recommendation, Assessment, Development, and Evaluation system. From a source of 120 potentially relevant articles, 14 provided applicable evidence. Procedures involving interlaminar access carry a nonzero risk of hemorrhagic complications, regardless of whether anticoagulants are ceased or continued. For other procedures, hemorrhagic complications have not been reported, and case series indicate that they are safe when performed in patients who continue anticoagulants. Three articles reported the adverse effects of ceasing anticoagulants, with serious consequences, including death. Other than for interlaminar procedures, the evidence does not support the view that anticoagulant and antiplatelet medication must be ceased before image-guided spine pain procedures. Meanwhile, the evidence shows that ceasing anticoagulants carries a risk of serious consequences, including death. Guidelines on the use of anticoagulants should reflect these opposing bodies of evidence.

    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 subgroup analysis of the Lifestyle Intervention and Independence for Elders trial evaluates the impact of a long-term physical activity (PA) intervention on rates of major mobility disability (MMD) among older adults according to their antihypertensive medication use. Lifestyle Intervention and Independence for Elders study participants were randomized to center-based PA or health education for a median of 2.7 years. Participants were sedentary men and women aged 70-89 years with objectively measured physical limitations. This analysis evaluated rates of MMD and persistent MMD among 1,633 participants, according to antihypertensive medication use. Participants were designated as either (i) an angiotensin-converting enzyme (ACE) inhibitor user (ACEi+), (ii) a user of other antihypertensives not including ACEi (ACEi-), or (iii) nonusers of antihypertensive medications (AHT-). Interactions were explored between antihypertensive use and randomized arm. Interaction terms for MMD (p = .214) and persistent MMD (p = .180) did not reach statistical significance. For MMD, PA displayed marginal effects among ACEi+ (hazard ratio [HR] = 0.76; 95% confidence interval [CI] = 0.57, 1.02) and ACEi- (HR = 0.76; 95% CI = 0.60, 0.97) but not AHT- (HR = 1.19; 95% CI = 0.75, 1.87). For persistent MMD, the effect of PA was greatest among ACEi+ (HR = 0.57; 95% CI = 0.39, 0.84) when compared to ACEi- (HR = 0.76; 95% CI = 0.55, 1.06) or AHT- (HR = 1.18; 95% CI = 0.59, 2.36). The effects of long-term PA on the incidence of MMD and persistent MMD were similar among three subgroups of older adults stratified by their antihypertensive medication use. However, though statistical interactions did not reach significance, several findings may warrant future study in other cohorts given the post hoc nature of this study. © The Author 2016.

    Building on a series of higher educational arts/medicine initiatives, an interdisciplinary drawing module themed on the human body was developed for both year 3 Craft students and year 3 Medicine degree students. This became the subject of a research project exploring how the collaborative approach to drawing adopted on this module impacted on the students' learning. In this article, emphasis is given to issues thought to have most potential relevance to medical education. Using an ethnographic research design, the methods adopted were: direct observation of all aspects of the module sessions, audio and video recordings and photographs of the sessions, the incorporation of a semi-structured discussion at the end of each session, and anonymous student questionnaires. A number of key themes emerged. The complex, phased and multi-sensory nature of the 'critical looking' skills developed through the drawing exercises was seen as of potential value in medical education, being proposed as analogous to processes involved in clinical examination and diagnosis. The experience of interdisciplinary collaborative drawing was significant to the students as a creative, participatory and responsive form of learning. The emphasis on the physical experience of drawing and the thematic use of the human body as drawing subject led to reflective discussions about bodily knowledge and understanding. There were indications that students had a meta-cognitive awareness of the learning shifts that had occurred and the sessions provoked constructive self-reflective explorations of pre-professional identity. This preliminary study suggests, through the themes identified, that there may be potential learning outcomes for medical students in this model of interdisciplinary collaborative drawing of the human body. Further research is needed to explore their applicability and value to medical education. There is a need to explore in more depth the beliefs, motivations and learning styles of

    Analyze the use of antihypertensives among seniors and the association with socioeconomic and behavioral characteristics. In this seriate cross-sectional study, we used data from the Saúde, Bem Estar e Envelhecimento study (SABE - Health, Well-being, and Aging), conducted in 2000, 2006, and 2010 in the city of São Paulo. Association between the use of antihypertensives and the demographic, behavioral, and socioeconomic characteristics and risk factors was analyzed by using multilevel logistic regression models. We observed increased proportion of use of antihypertensive, from 48.7% in 2000 to 61.3% in 2006, reaching 65.7% in 2010. Among the seniors who made use of this type of medicine, we also observed increased adoption of combined therapy in the period, from 69.9% to 82.6% from 2000 to 2006 and reaching 91.6% in 2010. Multilevel analysis indicated statistically significant increase in use of antihypertensives, even after control by socioeconomic and behavioral characteristics, both in 2006 and in 2010 (OR = 1.90; 95%CI 1.60-2.24 and OR = 1.94; 95%CI 1.62-2.33, respectively). Use of antihypertensives showed positive association with females, higher age group, black skin color, overweight, and smoking history. High use of antihypertensives and its association with sociodemographic and behavioral characteristics can help guide the discussion of strategies to improve the epidemiological situation, the quality of life, and the distribution of medicines to the elderly population.

    In order to study pharmacokinetics and pharmacodynamics of antihypertensive drugs in the elderly, plasma concentration and blood pressure response to 4 antihypertensive drugs with different modes of action (captopril, nifedipine retard tablet, bunazosin, arotinolol) were measured in young and elderly hypertensive patients without liver or renal dysfunction after oral administration of each drug. Systolic and diastolic blood pressure fell after 25 mg of captopril in both groups and the rate of decrease in each group was similar. Plasma concentration of captopril at 1 and 2 hours after administration in the elderly group tended to be higher than in the young group. Suppression of angiotensin-converting enzyme activity persisted longer in the elderly group than in the young group. The area under the curve (AUC) of captopril in the elderly group (335.4 +/- 98.6 hr.2ng/ml) was significantly greater than in the young group (186.7 +/- 79.9) (p less than 0.005), while no significant differences in Cmax, Tmax and T1/2 were observed. The percent decrease in systolic blood pressure in the elderly group (25.2 +/- 10.2%) after 1 hour of nifedipine tablet (20 mg) was significantly higher than in the young group (16.6 +/- 1.5%) (p less than 0.05). Cmax and AUC of nifedipine in the elderly tended to be higher than in the young group (303.5 v.s. 210.0 ng/ml and 1258.9 v.s. 725.1 hr.ng/ml, p less than 0.1, respectively).

    Randomized trials of hypertension have seldom examined heterogeneity in response to treatments over time and the implications for cardiovascular outcomes. Understanding this heterogeneity, however, is a necessary step toward personalizing antihypertensive therapy. We applied trajectory-based modeling to data on 39 763 study participants of the ALLHAT (Antihypertensive and Lipid-Lowering Treatment to Prevent Heart Attack Trial) to identify distinct patterns of systolic blood pressure (SBP) response to randomized medications during the first 6 months of the trial. Two trajectory patterns were identified: immediate responders (85.5%), on average, had a decreasing SBP, whereas nonimmediate responders (14.5%), on average, had an initially increasing SBP followed by a decrease. Compared with those randomized to chlorthalidone, participants randomized to amlodipine (odds ratio, 1.20; 95% confidence interval [CI], 1.10-1.31), lisinopril (odds ratio, 1.88; 95% CI, 1.73-2.03), and doxazosin (odds ratio, 1.65; 95% CI, 1.52-1.78) had higher adjusted odds ratios associated with being a nonimmediate responder (versus immediate responder). After multivariable adjustment, nonimmediate responders had a higher hazard ratio of stroke (hazard ratio, 1.49; 95% CI, 1.21-1.84), combined cardiovascular disease (hazard ratio, 1.21; 95% CI, 1.11-1.31), and heart failure (hazard ratio, 1.48; 95% CI, 1.24-1.78) during follow-up between 6 months and 2 years. The SBP response trajectories provided superior discrimination for predicting downstream adverse cardiovascular events than classification based on difference in SBP between the first 2 measurements, SBP at 6 months, and average SBP during the first 6 months. Our findings demonstrate heterogeneity in response to antihypertensive therapies and show that chlorthalidone is associated with more favorable initial response than the other medications. © 2017 American Heart Association, Inc.

    This study of informed consent examines understanding of information needed to consent to stimulant treatment for attention-deficit/hyperactivity disorder (ADHD). The understanding of adolescents with ADHD, their parents, control adolescents, and their parents is compared. Fifty-eight ADHD and 64 control adolescents between the ages of 12 and 16 and their parents were studied. Baseline understanding of information was determined. Subjects received information relevant to informed consent for stimulation medication and afterward were evaluated on their recall understanding and their final understanding. Knowledge was increased after the information session for all subjects. There was no significant difference between unadjusted baseline, recall, and final knowledge of control adolescents and parents. Although unadjusted baseline, recall, and final knowledge of ADHD adolescents is significantly less than that of parents, 78% of ADHD adolescents had final understanding scores within 2 standard deviations of parents' scores. After controlling for baseline understanding and cognitive variables, there was no significant difference between understanding of ADHD adolescents and ADHD parents, whereas control adolescents understanding scores were higher than that of their parents. Understanding was highly associated with mathematics achievement in all groups. The majority of adolescents with ADHD, both with and without a history of stimulant medication treatment, have understanding that is similar to their parents and their inclusion in the informed consent process should be encouraged. Extra care should be afforded to those adolescents with low numeracy or literacy to ensure their understanding.

    Salt-sensitive hypertension (SSH) is an intermediate inherited phenotype of essential hypertension as well as being an independent risk factor for cardiovascular disease. However, effective medications for the treatment of SSH have not been clarified. This study was to compare the efficacious of different classes of antihypertensive agents combined with salt intake on the reduction of blood pressure in patients with salt-sensitive hypertension (SSH). We used sources as PubMed, EMBASE, Cochrane Library, CENTRAL, ClinicalTrials.gov, ICTRP, CNKI and WANFANG database from inception to November 2016. Studies that compared the efficacy of two or more antihypertensive agents or placebos in adult salt-sensitive hypertensive patients were included. The outcomes included variations in mean arterial blood pressure, systolic and diastolic blood pressure. Twenty-five studies were involved in this meta-analysis. A CCB with hydrochlorothiazide and moderate salt intake was significantly the most efficacious in comparison with placebo [standardized mean differences (SMD), 95% credibility intervals (CI): 26.66, 12.60-40.16], ARBs [SMD, 95% CI: 22.94, 5.26-40.51] and the other interventions for patients with SSH and no concomitant diseases. For SSH patients who were obese, the effect size of CCB with metformin and moderate salt intake was [SMD, 95% CI: 17.90, 6.26 -29.33]. For SSH patients with no concomitant diseases, CCB combined with hydrochlorothiazide and moderate salt intake were optimal in reducing blood pressure, while CCB combined with metformin and moderate salt intake were the most efficacious at reducing blood pressure in SSH patients with coexisting obesity.

    Full Text Available Objectives: (1 To report the results of a pharmacist-directed cardiovascular risk management program; and (2 to identify obstacles faced by the pharmacists in the program implementation. Methods: The collaborators in this study included two local unions, a health benefit consulting company, and a community pharmacy. A total of 750 union workers with cardiovascular risk were informed about the cardiovascular risk management program. The program lasted six months, and the participation was voluntary. There were three group educational sessions with each session followed by a medication management service. A staff person of the health benefit consulting company and two pharmacists were interviewed via telephone. The interview questions were created according to the Gaps Model of Service Quality. The Gaps Model theorizes five gaps among consumer expectations, consumer perceptions, management perceptions of consumer expectations, service quality, service delivery, and external communications to consumers. The following data were collected: (1 types and quantity of drug therapy problems, (2 pharmacists' recommendations and prescribers' response, (3 patients' quality of life, disability days, and sick days, and (4 the experience of involved parties. Descriptive statistics were calculated. Results: Fifteen union workers participated in the program. For the participants, 35 drug-related problems were identified, with "need for additional therapy" and "dose too low" being the most common problems. To address these drug-related problems, pharmacists made 33 recommendations to prescribers, and prescribers accepted 55% of the recommendations. According to the interviews, there were three barriers faced by pharmacists to implement the program: lack of consensus about the recruitment, union workers' unawareness of the program's benefits, and limited support from the unions and the health benefit consulting company. Conclusions: It was difficult to recruit

    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

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.

    Astaxanthin is a natural antioxidant carotenoid that occurs in a wide variety of living organisms. We investigated, for the first time, antihypertensive effects of astaxanthin (ASX-O) in spontaneously hypertensive rats (SHR). Oral administration of ASX-O for 14 d induced a significant reduction in the arterial blood pressure (BP) in SHR but not in normotensive Wistar Kyoto (WKY) strain. The long-term administration of ASX-O (50 mg/kg) for 5 weeks in stroke prone SHR (SHR-SP) induced a significant reduction in the BP. It also delayed the incidence of stroke in the SHR-SP. To investigate the action mechanism of ASX-O, the effects on PGF(2alpha)-induced contractions of rat aorta treated with NG-nitro-L-arginine methyl ester (L-NAME) were studied in vitro. ASX-O (1 to 10 microM) induced vasorelaxation mediated by nitric oxide (NO). The results suggest that the antihypertensive effect of ASX-O may be due to a NO-related mechanism. ASX-O also showed significant neuroprotective effects in ischemic mice, presumably due to its antioxidant potential. Pretreatment of the mice with ASX-O significantly shortened the latency of escaping onto the platform in the Morris water maze learning performance test. In conclusion, these results indicate that astaxanthin can exert beneficial effects in protection against hypertension and stroke and in improving memory in vascular dementia.

Albuminuria level was detected by immunoturbometric method (Integra-700, Roche.Results. The drug combination B had the least cost. The drug combination C was the most effective. The drug combination C was the most economically rational. The drug combination A was the least economically rational for BP reduction. However the drug combination A was comparable with drug combination C in effects on quality of life and on endothelium function, and it was the most economically rational for albuminuria reduction.Conclusion. Indapamide retard plus perindopril combination is the most economically rational in patients with target-organ lesions (nephropathy. Lisinopril plus amlodipine combination is economically rational in patients without target-organ lesions.

    The use of cardiovascular drugs is related to the development of adverse drug reactions (ADRs) in about 24% of the patients in the Cardiovascular Care Unit. Here, we evaluated the ADRs in patients treated with antihypertensive drugs. The study was conducted in two phases: In the first phase, we performed a retrospective study on clinical records of Clinical Divisions (i.e., Internal Medicine Operative Unit and Geriatric Operative Unit) from January 1, 2012 to December 31, 2012. Moreover from January 1, 2013 to March 30, 2013 we performed a prospective study on the outpatients attending the Emergency Department (ED) of the Pugliese-Ciaccio Hospital of Catanzaro, by conducting patient interviews after their informed consent was obtained. The association between a drug and ADR was evaluated using the Naranjo scale. We recorded 72 ADRs in the Clinical Divisions and six in the ED, and these were more frequent in women. Using the Naranjo score, we showed a probable association in 92% of these reactions and a possible association in 8%. The most vulnerable age group involved in ADRs was that of the elderly patients. In conclusion, our results indicate that antihypertensive drugs may be able to induce the development of ADRs, particularly in elderly women receiving multiple drug treatment. Therefore, it is important to motivate the healthcare providers to understand their role and responsibility in the detection, management, documentation, and reporting of ADRs, as also all the essential activities for optimizing patient safety.

    This study evaluated the in vivo potential antihypertensive effect of hydroalcoholic extract of Syzygium cumini leaves (HESC) in normotensive Wistar rats and in spontaneously hypertensive rats (SHR), as well as its in vitro effect on the vascular reactivity of resistance arteries. The hypotensive effect caused by intravenous infusion of HESC (0.01-4.0 mg/kg) in anesthetized Wistar rats was dose-dependent and was partially inhibited by pretreatment with atropine sulfate. SHR received HESC (0.5 g/kg/day), orally, for 8 weeks and mean arterial pressure, heart rate, and vascular reactivity were evaluated. Daily oral administration of HESC resulted in a time-dependent blood pressure reduction in SHR, with a maximum reduction of 62%. In the endothelium-deprived superior mesenteric arteries rings the treatment with HESC reduced by 40% the maximum effect (E max⁡) of contraction induced by NE. The contractile response to calcium and NE of endothelium-deprived mesenteric rings isolated from untreated SHR was reduced in a concentration-dependent manner by HESC (0.1, 0.25, and 0.5 mg/mL). This study demonstrated that Syzygium cumini reduces the blood pressure and heart rate of SHR and that this antihypertensive effect is probably due to the inhibition of arterial tone and extracellular calcium influx.

    Cardiovascular disease remains the leading cause of death worldwide with hypertension being a major contributing factor to cardiovascular disease-associated mortality. On a population level, non-pharmacological approaches, such as alternative/complementary medicine, including phytochemicals, have the potential to ameliorate cardiovascular risk factors, including high blood pressure. Several epidemiological studies suggest an antihypertensive effect of garlic (Allium sativum) and of many its bioactive components. The aim of this review is to present an in-depth discussion regarding the molecular, biochemical and cellular rationale underlying the antihypertensive properties of garlic and its bioactive constituents with a primary focus on S-allyl cysteine and allicin. Key studies, largely from PubMed, were selected and screened to develop a comprehensive understanding of the specific role of garlic and its bioactive constituents in the management of hypertension. We also reviewed recent advances focusing on the role of garlic bioactives, S-allyl cysteine and allicin, in modulating various parameters implicated in the pathogenesis of hypertension. These parameters include oxidative stress, nitric oxide bioavailability, hydrogen sulfide production, angiotensin converting enzyme activity, expression of nuclear factor-κB and the proliferation of vascular smooth muscle cells. This review suggests that garlic and garlic derived bioactives have significant medicinal properties with the potential for ameliorating hypertension and associated morbidity; however, further clinical and epidemiological studies are required to determine completely the specific physiological and biochemical mechanisms involved in disease prevention and management.

    The present study was designed to evaluate the effects of the aqueous extract obtained from the mixture of fresh leaf of Persea americana, stems and fresh leaf of Cymbopogon citratus, fruits of Citrus medica and honey on ethanol and sucrose induced hypertension in rats. Rats were divided into eight groups of 6 rats each and daily treated for 5 weeks. The control group received distilled water (1 mL/kg) while rats of groups 2, 3 and 4 received ethanol 40 degrees (3 g/kg/day), 10% sucrose as drinking water and the two substances respectively. The remaining groups received in addition to sucrose and ethanol, the aqueous extract (50, 100 and 150 mg/kg) or nifedipine (10 mg/kg) respectively. Many parameters including hemodynamic, biochemical and histopathological were assessed at the end of the study. The concomitant consumption of ethanol and sucrose significantly (p cholesterol, LDL-cholesterol, triglycerides, atherogenic index, glucose, proteins, AST, ALT, creatinin, potassium, sodium and albumin increased while the HDL-cholesterol decreased under ethanol and sucrose feeding. Chronic ethanol and sucrose intake significantly decreased the activities of superoxide dismutase (SOD) and catalase (CAT) as well as the contents of reduced glutathione (GSH) and nitrites whereas elevated the malondialdehyde (MDA) levels. Histological analysis revealed among other vascular congestion, inflammation, tubular clarification and thickening of the vessel wall in rats treated with alcohol and sucrose. Administration of the aqueous extract or nifedipine prevented the hemodynamic, biochemical, oxidative and histological impairments induced chronic ethanol and sucrose consumption. Current results suggest that the aqueous extract used in this study possess antihypertensive activity against ethanol and sucrose induced hypertension in rats by the improvement of biochemical and oxidative status, and by protecting liver, kidney and vascular endothelium against damages induced by chronic

    The policy issue underlying this study is whether Medicare support for graduate medical education (GME) should be restructured to differentiate between programs that are less costly or are self-sustaining and those that are more costly to the sponsoring institution and its educational partners. The authors used available literature, interviews with individuals involved in operating GME programs, and analysis of administrative data to explore how the financial impact of operating residency training programs might differ by specialty. The study does not quantify the variation in financial impact, but it provides a framework for examining both the costs and benefits of operating GME programs to the sponsoring institution and its educational partners. It also identifies the major factors that are likely to affect financial performance and influence program offerings and size. Marginal financial impacts are more likely to influence sponsor decisions on changes in GME program size and offerings and help explain why GME program expansions are occurring without additional Medicare funding. If the hospital has service needs, there is a marginal benefit to adding a resident, particularly in the more-lucrative specialty and subspecialty programs, before considering the additional benefits of any Medicare GME-related revenues.

    Three hundred Irish Medical Organisation members were surveyed on health promotion and health and safety issues. 64.7% responded (65.3 males; 33.7% < thirty-five years). Over half (54.9%) were aware of the safety legislation and very few reported available occupational health services. A majority wanted more such services. Nearly all believed health promotion was important yet only 35.2% always availed of opportunities to give such advice. 36.3% were often stressed, particularly at work. Alcohol was sometimes or frequently used to cope by around half of respondents. Although less than half (47.7%) used whole milk, one third usually or always added salt to their food. 15.5% took no weekly aerobic exercise but 42.0% claimed to do so three times weekly. 11.4 were current smokers. A third of women had never had a cervical smear. We conclude doctors require adequate occupational health services.

    Although hypertension guidelines have utility in treating uncomplicated hypertension, they often overlook the pathophysiologic basis and heterogeneity of hypertension. This may explain the relatively poor hypertension control rates. A proposed approach is to guide addition and subtraction of medications using ambulatory plasma renin activity (PRA) values. To evaluate the heterogeneity of hypertension and the medication burden associated with it, we investigated medication usage in relation to PRA among hypertensive patients within a large ethnically diverse organization. A cross sectional data analysis was performed of hypertensive subjects with PRA measurements in the Kaiser Permanente Southern California database between 1 January 1998 and 31 October 2009. Among 7,887 such patients 0, 1, 2, ≥3 medication usage was 16%, 20%, 24%, 40% respectively. PRA levels ranged 1000-fold. Across PRA quartiles (Q1 to Q4) ≥3 meds were prescribed to 50%, 40%, 34%, 37%. From low to high PRA quartiles there was no usage trend for angiotensin converting enzyme inhibitors (ACEIs)/ angiotensin receptor blockers (ARBs) (71%), but diuretics increased (52%, 53%, 57%, 68%), calcium channel blocker's (CCB) fell (56%, 53%, 51%, 42%), and β-blockers fell (77%, 61%, 49%, 41%). Moreover, systolic BP fell (146, 142, 140, 135 mm Hg), blood urea nitrogen (BUN) rose (16, 17, 18, 20 mg/dl), serum uric acid rose (6.1, 6.3, 6.5, 6.9 mg/dl), and chronic kidney disease rose (22%, 22%, 23%, 27%). Polytherapy was the norm for treating hypertension. Lower PRAs were associated with higher blood pressures and more medications. Higher PRAs were associated with lower pressures and fewer medications. The results indicate that opportunities exist to simplify antihypertensive therapy by using current ambulatory PRA levels to guide drug selections and subtractions. © 2012 American Journal of Hypertension, Ltd.

    The diffusion of health technologies from translational research to reimbursement depends on several factors included the results of health economic analysis. Recent research identified several flaws in health economic concepts. Additionally, the heterogeneous viewpoints of participating stakeholders are rarely systematically addressed in current decision-making. Multi-criteria Decision Analysis (MCDA) provides an opportunity to tackle these issues. The objective of this study was to review applications of MCDA methods in decisions addressing the trade-off between costs and benefits. Using basic steps of the PRISMA guidelines, a systematic review of the healthcare literature was performed to identify original research articles from January 1990 to April 2014. Medline, PubMed, Springer Link and specific journals were searched. Using predefined categories, bibliographic records were systematically extracted regarding the type of policy applications, MCDA methodology, criteria used and their definitions. 22 studies were included in the analysis. 15 studies (68 %) used direct MCDA approaches and seven studies (32 %) used preference elicitation approaches. Four studies (19 %) focused on technologies in the early innovation process. The majority (18 studies - 81 %) examined reimbursement decisions. Decision criteria used in studies were obtained from the literature research and context-specific studies, expert opinions, and group discussions. The number of criteria ranged between three up to 15. The most frequently used criteria were health outcomes (73 %), disease impact (59 %), and implementation of the intervention (40 %). Economic criteria included cost-effectiveness criteria (14 studies, 64 %), and total costs/budget impact of an intervention (eight studies, 36 %). The process of including economic aspects is very different among studies. Some studies directly compare costs with other criteria while some include economic consideration in a second step.

    Increased arterial stiffness is a common characteristic of humans with Williams-Beuren syndrome and mouse models of elastin insufficiency. Arterial stiffness is associated with multiple negative cardiovascular outcomes, including myocardial infarction, stroke, and sudden death. Therefore, identifying therapeutic interventions that improve arterial stiffness in response to changes in elastin levels is of vital importance. The goal of this study was to determine the effect of chronic pharmacologic therapy with different classes of antihypertensive medications on arterial stiffness in elastin insufficiency. Elastin-insufficient mice 4-6 wk of age and wild-type littermates were subcutaneously implanted with osmotic micropumps delivering a continuous dose of one of the following: vehicle, losartan, nicardipine, or propranolol for 8 wk. At the end of treatment period, arterial blood pressure and large artery compliance and remodeling were assessed. Our results show that losartan and nicardipine treatment lowered blood pressure and pulse pressure in elastin-insufficient mice. Elastin and collagen content of abdominal aortas as well as ascending aorta and carotid artery biomechanics were not affected by any of the drug treatments in either genotype. By reducing pulse pressure and shifting the working pressure range of an artery to a more compliant region of the pressure-diameter curve, antihypertensive medications may mitigate the consequences of arterial stiffness, an effect that is drug class independent. These data emphasize the importance of early recognition and long-term management of hypertension in Williams-Beuren syndrome and elastin insufficiency.

    Efficient use of government funding has been increasingly relevant for the success and sustainability of ongoing health-system reform in China; however, as there is no generic substitution policy, patients and basic health-insurance programs pay more for public-preferred brand originators. Such phenomenon is especially typical in public hospitals. The objective of this study is to estimate the potential cost savings in procurement by Chinese public hospitals when switching from brand originators of anti-hypertensive and anti-diabetic medications to their generic equivalents between 2012-2014. IMS Health volume and value consumption data (IMS China Hospitals Audit system 2012-2014) were used, which covered all Chinese hospitals with 100 beds and above. The top 60% IMS volume consumption of respective anti-hypertensive and anti-diabetic medication with unique dosage form and strength were included. The potential cost savings were calculated from a switch of brand originators with their generic equivalents on the Chinese and international market. An independent sample t-test was conducted to compare the difference of proportion of cost savings in value between the Chinese and international market. An average of 44% (US$44 million) and 87% (US$90 million) and a total of US$1.4 and 2.8 billion (2014 US$) could be saved from a switch from originator brand anti-hypertensives and anti-diabetics to domestically and internationally available generic equivalents, respectively. The differences of cost savings (in proportion) between domestic and international market were statistically significant (α = 0.005, p = 0.003, p = 0.002, p = 0.000). Expensive brand originators dominated the anti-hypertensive and anti-diabetic market in Chinese hospitals between 2012-2014. Preference of brand originators wastes a huge amount of health resources in China and these limited resources could have been used more efficiently. As one of the world's key generic suppliers, if

    Full Text Available Objectives: (1 To report the results of a pharmacist-directed cardiovascular risk management program; and (2 to identify obstacles faced by the pharmacists in the program implementation. Methods: The collaborators in this study included two local unions, a health benefit consulting company, and a community pharmacy. A total of 750 union workers with cardiovascular risk were informed about the cardiovascular risk management program. The program lasted six months, and the participation was voluntary. There were three group educational sessions with each session followed by a medication management service. A staff person of the health benefit consulting company and two pharmacists were interviewed via telephone. The interview questions were created according to the Gaps Model of Service Quality. The Gaps Model theorizes five gaps among consumerexpectations, consumer perceptions, management perceptions of consumer expectations, service quality, service delivery, and external communications to consumers. The following data were collected: (1 types and quantity of drug therapy problems, (2 pharmacists’ recommendations and prescribers' response, (3 patients’ quality of life, disability days, and sick days, and (4 the experience of involved parties. Descriptive statistics were calculated.Results: Fifteen union workers participated in the program. For the participants, 35 drug-related problems were identified, with “need for additional therapy” and “dose too low” being the most common problems. To address these drug-related problems, pharmacists made 33 recommendations to prescribers, and prescribers accepted 55% of the recommendations. According to the interviews, there were three barriers faced by pharmacists to implement the program: lack of consensus about the recruitment, union workers’ unawareness of the program’s benefits, and limited support from the unions and the health benefitconsulting company.Conclusions: It was difficult to

Aim: Using a nationally representative sample, the current study aimed to examine if the protective effect of income on chronic medical conditions (CMC differs for African Americans compared to Whites. Methods: With a cross-sectional design, the National Survey of American Life (NSAL, 2003, included 3570 non-Hispanic African Americans and 891 non-Hispanic Whites. The dependent variable was CMC, treated as a continuous measure. The independent variable was income. Race was the focal moderator. Age, education, and marital status were covariates. Linear regressions were used to test if the protective effect of income against CMC varies by race. Results: High income was associated with a lower number of CMC in the pooled sample. We found a significant interaction between race and income, suggesting that income has a smaller protective effect against CMC for African Americans than it does for Whites. Conclusion: Blacks’ diminished return also holds for the effects of income on CMC. Blacks’ diminished return is a contributing mechanism to the racial disparities in health in the United States that is often overlooked. More research is needed on the role of diminished health return of SES resources among other minority groups.

    Men and women returning from the wars in Afghanistan and Iraq face a multitude of difficulties while integrating back into civilian life, but the importance of their veteran status is often overlooked in primary care settings. Family physicians have the potential to be the first line of defense to ensure the well-being of veterans and their families because many will turn to nonmilitary and non-Veterans Affairs providers for health care needs. An awareness of the unique challenges faced by this population is critical to providing care. A patient-centered medical home orientation can help the family physician provide veterans and their families the care they need. Specific recommendations for family physicians include screening their patient population; providing timely care; treating the whole family; and integrating care from multiple disciplines and specialties, providing veterans and families with "one-stop shopping" care. An awareness of the unique challenges faced by veterans and their families translates into better overall outcomes for this population.

    Introduction Autoimmune pemphigus diseases comprise several entities with serious prognoses, including the pemphigus vulgaris (PV) group and pemphigus foliaceus (PF) group. Antihypertensives are suspected to be one of the factors triggering/sustaining pemphigus. Here, the data of pemphigus patients regarding arterial hypertension (AH) and taking potentially noxious drugs were statistically analyzed in a setting of a Polish university dermatology department. Material and methods Medical histories of pemphigus patients (40 admissions of 24 female patients – 13 PV, 11 PF; and 102 admissions of 38 male patients – 24 PV, 14 PF), diagnosed at both immunopathological and biochemical-molecular levels, were studied. Results Ten of 16 (62.50%) AH-positive PV patients received known PV triggers/sustainers 11 times (1–3 per patient). Fourteen of 15 (93.33%) AH-positive PF patients received known PF triggers/sustainers 21 times (1–3 per patient). No differences in numbers of patients taking potentially culprit drugs were shown between PV and PF (Fisher's exact test: p = 0.0829; Yates’ χ2 test: p = 0.1048). The most frequently used culprit drugs were ramipril in PV and enalapril in PF. On average, each PV/PF AH-positive patient received 3.161 different antihypertensives in his/her history of admissions (2.155 antihypertensives per admission). Conclusions Drug triggering should be suspected in every case of newly diagnosed or exacerbated pemphigus, as eliminating possible PV/PF triggers/sustainers may alleviate the clinical symptoms and enable the decrease of dose/range of immunosuppressants regardless of pemphigus form. Eliminating possible drug PV/PF triggers/sustainers may alleviate the clinical symptoms and enable the decrease of dose/range of immunosuppressants regardless of pemphigus form. PMID:26528346

    Telemedicine is a rapidly evolving form of modern information and communication technology used to deliver clinical services and educational activities. The aim of this article is to report and analyze our experience with transatlantic consultation via videoconferencing in pediatric cardiology. In February, 2013, videoconferencing project was launched between a medium-volume pediatric cardiac center in Bratislava, Slovakia and subspecialty experts from a high-volume pediatric cardiac program at The Children's Hospital of Philadelphia (CHOP), USA. During 1.5-2 hours videoconferences, 2-3 patients with similar complex clinical scenarios were presented to CHOP experts. The main goal of the project was consultation on individual patients to validate, alter or radically change clinical management plans. From February, 2013 to January, 2017, 25 videoconferences occurred and 73 cases were discussed. The median patient age was 52 months (range; 1 day-30 years). Forty-six discussed cases were outpatients, 21 patients were in the intensive care unit and 6 patients were discussed post mortem. Thirty-one CHOP experts from different subspecialties participated actively in patient consultations. The most frequent recommendations were related to single ventricle, pulmonary hypertension or heart failure patients and intervention in complex and/or rare cardiac diseases. Specialists from CHOP agreed completely with the original care plan in 16% of cases. In 52% cases, adjustments to original plan were suggested. Radical changes were recommended in 30% of cases. Receiving institution adopted recommendations to the patient care fully in 79% and partially in 13% of patients.

    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.

    Full Text Available [english] Objective: The integration of scientific research into medical education is a widely discussed topic. Most research training programs are offered on a voluntary basis. In Germany, it is mandatory to complete a doctoral thesis to obtain the academic title “doctor”. The reasons why students start a dissertation project and the influence of this project on their undergraduate studies and later career choices are not well known.Method: This study was conducted at five German universities in 2003, with a total of 437 fifth-year students participating in it. A standardised questionnaire was used to ask participants about their current or finished dissertation (group A, a dissertation they had discontinued (group B or why they had never started a dissertation project (group C.Results: The two most important reasons for students from group A to start a dissertation were “interest in the topic” and “advantage for job applications”. Compared with group B, they mentioned “improved ability to critically appraise scientific studies” and “doing scientific work independently” significantly more often as a result of working on their dissertation. Starting a dissertation project early during undergraduate studies was correlated with a less successful outcome. Moreover, working on a dissertation significantly reduced time spent on undergraduate studies. Students from group C named the "workload of undergraduate studies" and “no time” most frequently as reasons for not having started a dissertation.Conclusion: Students who have been working successfully on a dissertation rate items regarding the acquisition of scientific research skills significantly more positively, and participation in undergraduate studies seems to be negatively affected by working on a dissertation project. Therefore, basic training in scientific research methodology should become an integrated part of the medical undergraduate curriculum, while special

    Imperatorin (Imp) as a hypotensive active ingredient, its hypotensive effect was evaluated in the SHRs, its calcium antagonism and affinity to L-type calcium channel was also confirmed. The results showed that the blood pressure was decreased in the SHRs treated with Imp, the aortic ring was relaxed with Imp, L-type calcium channel currents and intracellular calcium free ion rise was nearly disappeared when adding Imp. In addition, Imp displayed a chromatographic peak similar to nitrendipine and verapamil by the cell membrane chromatography, same results from protein-drug docking approaches. Hence, Imp target the L-type calcium channel, and may be used as a novel antihypertensive drug. Copyright © 2011 Elsevier B.V. All rights reserved.

    Bioactive peptides from food proteins exert beneficial effects on human health, such as angiotensin-converting enzyme (ACE) inhibition and antihypertensive activity. Several studies have reported that ACE-inhibitory peptides can come from animal products, marine organisms, and plants-derived by hydrolyzing enzymes such as pepsin, chymotrypsin, and trypsin-and microbial enzymes such as alcalase, thermolysin, flavourzyme, and proteinase K. Different ACE-inhibitory effects are closely related with different peptide sequences and molecular weights. Sequences of ACE-inhibitory peptides are composed of hydrophobic (proline) and aliphatic amino acids (isoleucine and leucine) at the N-terminus. As result of this review, we assume that low molecular weight peptides have a greater ACE inhibition because lower molecular weight peptides have a higher absorbency in the body. Therefore, the ACE-inhibitory effect is closely related with the degree of enzymatic hydrolysis and the composition of the peptide sequence. Copyright © 2017 Elsevier Ltd. All rights reserved.

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.

    : Aerobic exercise training and, to a lesser degree, dynamic resistance training, are recommended to lower blood pressure (BP) among adults with hypertension. Yet the combined influence of these exercise modalities, termed concurrent exercise training (CET), on resting BP is unclear. This study aimed to meta-analyze the literature to determine the efficacy of CET as antihypertensive therapy. Electronic databases were searched for trials that included the following: adults (>19 yr), controlled CET interventions, and BP measured pre- and postintervention. Study quality was assessed with a modified Downs and Black Checklist. Analyses incorporated random-effects assumptions. Sixty-eight trials yielded 76 interventions. Subjects (N = 4110) were middle- to older-age (55.8 ± 14.4 yr), were overweight (28.0 ± 3.6 kg·m), and had prehypertension (systolic BP [SBP]/diastolic BP [DBP] = 134.6 ± 10.9/80.7 ± 7.5 mm Hg). CET was performed at moderate intensity (aerobic = 55% maximal oxygen consumption, resistance = 60% one-repetition maximum), 2.9 ± 0.7 d·wk for 58.3 ± 20.1 min per session for 19.7 ± 17.8 wk. Studies were of moderate quality, satisfying 60.7% ± 9.4% of quality items. Overall, CET moderately reduced SBP (db = -0.32, 95% confidence interval [CI] = -0.44 to -0.20, -3.2 mm Hg) and DBP (db = -0.35, 95% CI = -0.47 to -0.22, -2.5 mm Hg) versus control (P training as antihypertensive therapy. Because of the moderate quality of this literature, additional randomized controlled CET trials that examine BP as a primary outcome among samples with hypertension are warranted to confirm our promising findings.

They were split in two groups. Patients of the first group (30 people received enalapril (Berlipril® 20 mg/daily, patients of the second group (30 people – diltiazem (Altiazem® PP 180-360 mg/daily. Observation period was 6 months. Ambulatory blood pressure monitoring (ABPM was performed before treatment and after 3 weeks, 1, 3 and 6 months of therapy. Climacteric syndrome severity and urodynamic disorders was estimated as well as psychic status according to score of depression and anxiety.Results. Office and ambulance blood pressure decreased after 6 months of therapy in all patients of both groups. A number of complaints on headache and giddiness reduced significantly. Severity of climacteric syndrome also decreased. Enalapril (Berlipril® monotherapy and especially combined therapy with hydrochlorothiazide led to aggravation of urodinamic disorders. On the contrary both monotherapy with diltiazem (Altiazem® PP or its combination with hydrochlorothiazide had positive effect on urodinamics. Both therapies reduced depression and anxiety levels significantly.Conclusion. All spectrum of pharmacology effects should be taken into account during antihypertensive therapy of patients with climacteric disorders.

    Ficus carica L. (Moraceae) fruit is said to possess cardiovascular activity and has been used empirically in traditional phytotherapies for the treatment of hypertension and various other cardiovascular diseases. This study investigated the antihypertensive and cardioinhibitory activity of the aqueous-methanol extract of F. carica fruit in rats. Extract in 250, 500 and 1000 mg/kg doses (p.o.) were administered to normotensive Sprague Dawley rats and blood pressure was measured using non-invasive technique. Hypertension was induced in rats by oral administration of 10% glucose for 3 weeks. Hypotensive effect of extract (1000 mg/kg p.o) was studied in normotensive and glucose-treated hypertensive rats. Langendorff's isolated heart technique was used to assess the effect of crude extract on force of contraction and heart rate. In addition, antioxidant potential, TPC, TFC were also assessed by DPPH free radical scavenging activity, Folin-Ciocalteu reagent and AlCl 3 assay, respectively. Furthermore, phenolic compounds were analyzed using HPLC-DAD technique. The 1000 mg/kg dose decreased blood pressure significantly in normotensive and glucose-treated hypertensive rats. The isolated heart study showed that the extract produced negative inotropic and chronotropic effects but it failed to block the stimulatory effect of both adrenaline and CaCl 2 . HPLC studies on the F. carica extract indicated the presence of quercetin, gallic acid, caffeic acid, vanillic acid, syringic acid, coumaric acid and chromotropic acid. This study demonstrated that aqueous methanol extract of F. carica fruit exerted hypotensive and antihypertensive effects in glucose-induced hypertensive rats.

    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.

    Diagnostic and therapeutic radiology is playing a major role in modern medicine. The utilization of devices emitting ionizing radiation for medical diagnostic and therapeutic purposes is classified into three categories: a. Radiotherapy procedures for the treatment of malignant and benign tumors. b. Nuclear medicine procedures using radiopharmaceuticals that are introduced into the patient's body for diagnostic and therapeutic purposes. c. Diagnostic and therapeutic x-ray imaging procedures. This group includes conventional radiography, conventional fluoroscopy, cardiac catheterization, angiography, CT, mammography, dental, and fluoroscopy operation procedures. A survey was carried out on a sample of three major Israeli hospitals in order to: 1. Determine the status of radiation protection of patients in Israel with regard to the use of x-rays in medical imaging and interventional radiology. 2. Assess the extent of exposure of the population to medical x-rays, and assess the collective risk in Israel in this relation (based on Icr-60). 3. Carry out a cost-benefit optimization procedure related to the means that should be used to reduce the exposure of Israeli patients under x-ray procedures. 4. Establish a of practical recommendations to reduce the x-ray radiation exposure of patients and to increase the image quality. 5. Establish a number of basic rules to be utilized by health policy makers in Israel

    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 (P<0.001), with increased stiffness observed in even the youngest children with Williams 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.

    Hypertension is a major independent risk factor for cardiovascular diseases. 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 for documenting dipping/nondipping status so far. This monitoring technique is expensive and inconvenient for routine usage. Simpler methods using home blood pressure monitoring systems are evolving to document basal blood pressure in the night, which would help in greater acceptance and use of the concept of dipper/nondipper in managing hypertension at the primary care level.

    To evaluate the efficacy of a healthcare education program for patients with hypertension. A multicenter, prospective, cluster-randomized trial was conducted. Randomization was by primary care center; 18 of 36 urban primary care centers in Barcelona and its metropolitan area were randomized to the intervention group (IG) and 18 to the control group (CG). The study sample consisted of patients with hypertension (n=996; 515 in the IG and 481 in the CG) receiving outpatient treatment with antihypertensive drugs. The intervention consisted of personalized information by a trained nurse and written leaflets. Questionnaires on knowledge and awareness of hypertension and its medication, treatment adherence, healthy lifestyle habits, systolic and diastolic blood pressure, and body mass index were assessed at each visit, with a 12-month follow-up. An intention-to-treat analysis was applied. Knowledge of hypertension increased by 27.8% in the IG and by 18.5% in the CG, while that of medication increased by 10.1% in the IG and 5.5% in the CG. Treatment adherence measured by the Morisky-Green test increased by 9.6% (95% CI: 5.5-13.6) in the IG and 8.8% (95% CI: 4.9-12.6) in the CG. There were no differences in adherence on the other tests used. No differences were observed between the IG and CG in clinical variables such as blood pressure or BMI at the end of the trial. The educational intervention had no significant impact on patients' adherence to the medication. Copyright © 2010 SESPAS. Published by Elsevier Espana. All rights reserved.

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

    To evaluate the association between the development of sight-threatening diabetic retinopathy (STDR) and antihypertensive drugs (AHDs) use among type 2 diabetic patients with concomitant hypertension. Type 2 diabetic patients aged 20-100 years who had at least one prescription for AHDs between 2000 and 2011 were identified from the Longitudinal Health Insurance Database (LHID) 2005. The incidence rates of STDR were followed and Cox proportional hazard models were used to analyze the risk associated with AHDs. Users of angiotensin-converting enzyme inhibitors (ACEIs) and angiotensin receptor blockers (ARBs) were associated with a significantly higher risk than users of calcium channel blockers (CCBs), independent of baseline characteristics. After adjusting for time-varying use of concomitant medications for propensity score-matched or -unmatched cohorts, the results showed that patients receiving ACEIs/ARBs and CCBs were associated with a significantly greater risk compared with β-blocker users. Our study did not support a superiority of ACEIs/ARBs and CCBs over β-blockers for lowering the progression of diabetic retinopathy. © 2015 S. Karger AG, Basel.

    Full Text Available Superoxide (O2-• has been implicated in the pathogenesis of many human diseases including hypertension. Mitochondria-targeted superoxide scavenger mitoTEMPO reduces blood pressure; however, the structure–functional relationships in antihypertensive effect of mitochondria-targeted nitroxides remain unclear. The nitroxides are known to undergo bioreduction into hydroxylamine derivatives which reacts with O2-• with much lower rate. The nitroxides of pyrrolidine series (proxyls are much more resistant to bioreduction compared to TEMPOL derivatives suggesting that mitochondria-targeted proxyls can be effective antioxidants with antihypertensive activity. In this work we have designed and studied two new pyrrolidine mitochondria targeted nitroxides: 3-[2-(triphenyphosphonioacetamido]- and 3-[2-(triphenyphosphonio acetamidomethyl]-2,2,5,5-tetramethylpyrrolidine-1-oxyl (mCP2 and (mCP1. These new mitochondria targeted nitroxides have 3- to 7-fold lower rate constants of the reaction with O2-• compared with mitoTEMPO; however, the cellular bioreduction of mCP1 and mCP2 was 3- and 2-fold slower. As a consequence incubation with cells afforded much higher intracellular concentration of mCP1 and mCP2 nitroxides compared to mitoTEMPO nitroxide. This has compensated for the difference in the rate of O2-• scavenging and all nitroxides similarly protected mitochondrial respiration in H2O2 treated endothelial cells. Treatment of hypertensive mice with mCP1 and mCP2 (1.4 mg/kg/day after onset of angiotensin II-induced hypertension significantly reduced blood pressure to 133±5 mmHg and 129±6 mmHg compared to 163±5 mmHg in mice infused with angiotensin II alone. mCP1 and mCP2 reduced vascular O2-• and prevented decrease of endothelial nitric oxide production. These data indicate that resistance to bioreduction play significant role in antioxidant activity of nitroxides. Studies of nitroxide analogs such as mCP1 and mCP2 may help in optimization

    Previous studies of antihypertensive treatment of older patients have focused on blood pressure control, cardiovascular risk or adherence, whereas data on inappropriate antihypertensive prescriptions to older patients are scarce. The aim of the study was to assess inappropriate antihypertensive prescriptions to older patients. An observational, prospective multicentric study was conducted to assess potentially inappropriate prescription of antihypertensive drugs, in patients aged 75 years and older with arterial hypertension (HTN), in the month prior to hospital admission, using four instruments: Beers, Screening Tool of Older Person's Prescriptions (STOPP), Screening Tool to Alert Doctors to the Right Treatment (START) and Assessing Care of Vulnerable Elders 3 (ACOVE-3). Primary care and hospital electronic records were reviewed for HTN diagnoses, antihypertensive treatment and blood pressure readings. Of 672 patients, 532 (median age 85 years, 56% female) had HTN. 21.6% received antihypertensive monotherapy, 4.7% received no hypertensive treatment, and the remainder received a combination of antihypertensive therapies. The most frequently prescribed antihypertensive drugs were diuretics (53.5%), angiotensin-converting enzyme inhibitors (ACEIs) (41%), calcium antagonists (32.2%), angiotensin receptor blockers (29.7%) and beta-blockers (29.7%). Potentially inappropriate prescription was observed in 51.3% of patients (27.8% overprescription and 35% underprescription). The most frequent inappropriately prescribed drugs were calcium antagonists (overprescribed), ACEIs and beta-blockers (underprescribed). ACEI and beta-blocker underprescriptions were independently associated with heart failure admissions [beta-blockers odds ratio (OR) 0.53, 95% confidence interval (CI) 0.39-0.71, p treatment. Underprescription was more frequent than overprescription. ACEIs and beta-blockers were frequently underprescribed and were associated with heart failure admissions.

  14. Preclinical studies of indapamide, a new 2-methylindoline antihypertensive diuretic

    Energy Technology Data Exchange (ETDEWEB)

    Pruss, T.; Wolf, P.S.

    1983-07-01

    Indapamide is a new indoline antihypertensive diuretic agent whose chemical structure differs substantially from those of the thiazides. The hydrophobic indoline moiety of indapamide confers a lipid solubility to the molecule that is 5 to 80 times greater than that of the thiazide diuretics. Thus indapamide accumulates in vascular smooth muscle at a concentration 10 times higher than that of protein-free perfusate. The affinity of indapamide for vascular smooth muscle manifests itself in vitro and in vivo as a decrease in reactivity following various pharmacologic interventions. Moreover, in vitro studies have demonstrated that indapamide decreases the inward calcium current and the transmembrane influx of calcium. The diuretic effect of indapamide is predominantly due to inhibition of sodium reabsorption at the cortical diluting segment of the distal convoluted tubule. In animal studies, intravenous indapamide has no effect on glomerular filtration rate or renal blood flow. Indapamide is well absorbed and extensively metabolized in animals and humans, with biliary excretion being the predominant route of elimination in animals. Most important, repeat administration of indapamide to dogs with both kidneys removed produces no accumulation of intact indapamide or its metabolites. Extensive drug safety studies in animals indicate that indapamide produces no overt toxicity and exhibits a good margin of safety.

    Moxonidine (4-chloro-N-(4, 5-dihydro-1H-imidazol-2-yl)-6-methoxy-2-methyl-5-pyrimidinamine, BDF 5895) reduces blood pressure and heart rate in rats with genetic hypertension (SHR/Okamoto) and in rats with renovascular hypertension (Goldblatt 1 k/1 c). The hypotensive action was also confirmed in renal-hypertensive dogs. The hypotensive action is preceded by a reduction in plasma noradrenaline concentration, thus reflecting a reduction in sympathetic activity. In anesthetized cats, administration of moxonidine into the vertebral artery induces a greater hypotensive effect than i.v. injection of same doses, indicating the central nervous system as the site of hypotensive action. Similar to clonidine, the hypotensive action of moxonidine is abolished by pretreatment of the animals with a selective alpha 2-antagonist. Direct application of moxonidine into the cisterna magna of anesthetized rabbits revealed a 10-fold greater hypotensive potency than clonidine, in contrast to i.v. application where moxonidine was 10-fold less potent than clonidine. At least 10-fold higher doses of moxonidine were needed to cause side effects (sedation, inhibition of gastric secretion), when compared with clonidine. Interruption of presynaptic noradrenergic pathways completely abolished the hypotensive action of moxonidine. Thus moxonidine is endowed with a specific central site of action, presumably by stimulating central presynaptic alpha 2-adrenoceptors. This specific central hypotensive action enables a greater dissociation between the antihypertensive effect on the one hand, and the side effects on the other.

    The aim of this work was to produce antihypertensive protein hydrolysates through different forms of enzymatic hydrolysis (2% pepsin, 4% pepsin, 1% alcalase, 2% alcalase, 2% papain, and 2% pepsin + pancreatin) of hemp seed proteins (HSP). The hemp seed protein hydrolysates (HPHs) were tested for in vitro inhibitions of renin and angiotensin-converting enzyme (ACE), two of the enzymes that regulate human blood pressure. The HPHs were then administered orally (200 mg/kg body weight) to spontaneously hypertensive rats and systolic blood pressure (SBP)-lowering effects measured over a 24 h period. Size exclusion chromatography mainly showed a 300-9560 Da peptide size range for the HPHs, while amino acid composition data had the 2% pepsin HPH with the highest cysteine content. Fluorescence spectroscopy revealed higher fluorescence intensities for the peptides when compared to the unhydrolyzed hemp seed protein. Overall, the 1% alcalase HPH was the most effective (p alcalase) with the longer-lasting HPHs (2% and 4% pepsin) could provide daily effective SBP reductions.

    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.

    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.

    Prevention and optimal management of hypertension in the general population is paramount to the achievement of the World Heart Federation (WHF) goal of reducing premature cardiovascular disease (CVD) mortality by 25% by the year 2025 and widespread access to good quality antihypertensive medicines is a critical component for achieving the goal. Despite research and evidence relating to other medicines such as antimalarials and antibiotics, there is very little known about the quality of generic antihypertensive medicines in low-income and middle-income countries. The aim of this study was to determine the physicochemical equivalence (percentage of active pharmaceutical ingredient, API) of generic antihypertensive medicines available in the retail market of a developing country. An observational design will be adopted, which includes literature search, landscape assessment, collection and analysis of medicine samples. To determine physicochemical equivalence, a multistage sampling process will be used, including (1) identification of the 2 most commonly prescribed classes of antihypertensive medicines prescribed in Nigeria; (2) identification of a random sample of 10 generics from within each of the 2 most commonly prescribed classes; (3) a geographical representative sampling process to identify a random sample of 24 retail outlets in Nigeria; (4) representative sample purchasing, processing to assess the quality of medicines, storage and transport; and (5) assessment of the physical and chemical equivalence of the collected samples compared to the API in the relevant class. In total, 20 samples from each of 24 pharmacies will be tested (total of 480 samples). Availability of and access to quality antihypertensive medicines globally is therefore a vital strategy needed to achieve the WHF 25×25 targets. However, there is currently a scarcity of knowledge about the quality of antihypertensive medicines available in developing countries. Such information is important

    Hypertension is a leading cause of morbidity and mortality worldwide. Individuals with hypertension are at increased risk of stroke, heart disease and kidney failure. Both genetic and lifestyle factors, particularly diet, have been attributed an important role in the development of hypertension. Reducing dietary sugar and salt intake can help lower blood pressure; similarly, adequate protein intake may also attenuate hypertension. Observational, cross-sectional and longitudinal epidemiological studies, and controlled clinical trials, have documented significant inverse associations between protein intake and blood pressure. Human and animal studies have shown that specific amino acids within proteins may have antihypertensive effects. Cysteine, glutathione (a tripeptide), glutamate and arginine attenuate and prevent alterations that cause hypertension including insulin resistance, decreased nitric oxide bioavailability, altered renin angiotensin system function, increased oxidative stress and formation of advanced glycation end products. Leucine increases protein synthesis in skeletal muscle and improves insulin resistance by modulating hepatic gluconeogenesis. Taurine and tryptophan attenuate sympathetic nervous system activity. Soy protein helps lower blood pressure through its high arginine content and antioxidant activity exhibited by isoflavones. A diet containing an ample amount of protein may be a beneficial lifestyle choice for individuals with hypertension; one example is the Dietary Approaches to Stop Hypertension (DASH) diet, which is low in salt and saturated fat; includes whole grains, lean meat, poultry, fish and nuts; and is rich in vegetables, fruits and low-fat dairy products, which are good sources of antioxidant vitamins, minerals and fibre. Including an adequate supply of soy in the diet should also be encouraged.

    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.

  4. Differences in need for antihypertensive drugs among those aware and unaware of their hypertensive status: a cross sectional survey

    Full Text Available Abstract Background Lack of antihypertensive use among hypertensive individuals is a major public health problem. It remains unclear as to how much of this lack of treatment is because of failure to diagnose hypertension or failure to initiate drug treatment for those with a diagnosis of hypertension. The primary aim of this study was to determine the proportion of those untreated individuals who would be recommended to start drug therapy for control of blood pressure among those aware or unaware of their diagnosis of hypertension. Methods The Canadian Heart Health Surveys (1986 – 1992, a national, cross-sectional descriptive survey (n = 23 129, was used to determine the proportion of individuals who were untreated, yet satisfied the 2004 Canadian hypertension guidelines for initiating drug therapy. Patients were divided into subgroups of those aware and unaware of having a diagnosis of hypertension according to self reported awareness from the survey. Results Of those with untreated hypertension (= 140/90 mmHg, only 37% were aware of their diagnosis. 74% of untreated individuals aware of their diagnosis of hypertension would require drug therapy, compared to 57% of those who were unaware. Of those >65 years of age, 52% of aware individuals needed drug therapy whereas only 34% of unaware elderly would need drug treatment. Conclusion In both unaware and aware subgroups, the majority of patients with untreated hypertension would benefit from antihypertensive drug therapy according to the 2004 Canadian Hypertension recommendations. The proportion of untreated patients that still need drug therapy was higher among those who were aware compared to those who were unaware. This finding suggests that the major gap in hypertension control may be in initiating drug therapy rather than in diagnosing hypertension. Further studies are needed to confirm these results to ultimately help strategize public health efforts in controlling hypertension.

    Drug discovery and development is a high-risk enterprise that requires significant investments in capital, time and scientific expertise. The studies of xenobiotic metabolism remain as one of the main topics in the research and development of drugs, cosmetics and nutritional supplements. Antihypertensive drugs are used for the treatment of high blood pressure, which is one the most frequent symptoms of the patients that undergo cardiovascular diseases such as myocardial infraction and strokes. In current cardiovascular disease pharmacology, four drug clusters - Angiotensin Converting Enzyme Inhibitors, Beta-Blockers, Calcium Channel Blockers and Diuretics - cover the major therapeutic characteristics of the most antihypertensive drugs. The pharmacokinetic and specifically the metabolic profile of the antihypertensive agents are intensively studied because of the broad inter-individual variability on plasma concentrations and the diversity on the efficacy response especially due to the P450 dependent metabolic status they present. Several computational methods have been developed with the aim to: (i) model and better understand the human drug metabolism; and (ii) enhance the experimental investigation of the metabolism of small xenobiotic molecules. The main predictive tools these methods employ are rule-based approaches, quantitative structure metabolism/activity relationships and docking approaches. This review paper provides detailed metabolic profiles of the major clusters of antihypertensive agents, including their metabolites and their metabolizing enzymes, and it also provides specific information concerning the computational approaches that have been used to predict the metabolic profile of several antihypertensive drugs.

    Renal disease is highly prevalent in people with type 2 diabetes, and co-existence with hypertension increases the risk of cardiac events and mortality. Despite many large randomized trials, controversies remain regarding optimal antihypertensive therapy in diabetic patients, including whether some classes of antihypertensive drugs have specific renal protective properties, and the relationships between renal, cardiovascular and mortality endpoints. In this article, we review landmark antihypertensive drug trials from the last two decades in patient populations composed, or including substantial proportions, of patients with type 2 diabetes. Several points emerge. Firstly, treatment effects can vary widely among different renal, cardiovascular and mortality endpoints. Secondly, combinations of antihypertensive drugs vary in their ability to prevent major renal and cardiovascular events, even if they produce similar reductions in blood pressure. Thirdly, simply adding further antihypertensive drugs may not improve outcomes, even if it produces further reductions in blood pressure. In most trials, a reduction in microalbuminuria was associated with evidence of renal protection, but further evidence is needed relating changes in proteinuria with cardiovascular risk. The study that aligns best with the current reappraisal of ESH guidelines, with regard to blood pressure goals, use of an adequate combination and simultaneously protecting the kidney and the cardiovascular system, is the ADVANCE study.

    Hypertension and chronic kidney disease (CKD) are common comorbidities. Guidelines recommend treating hypertension in children with CKD because it is a modifiable risk factor for subsequent cardiovascular disease. Children with CKD are frequently excluded from antihypertensive drug trials. Consequently, safety and efficacy data for antihypertensive drugs are lacking in children with CKD. We determined the incidence of adverse events in 10 pediatric antihypertensive trials to determine the effect of renal function on antihypertensive safety and efficacy in children. These trials were submitted to the US Food and Drug Administration from 1998 to 2005. We determined the number and type of adverse events reported during the trials and compared these numbers in participants with normal renal function and those with decreased function (defined as an estimated glomerular filtration rate [eGFR] children in the 10 studies, 315 had decreased renal function. We observed no difference between the two cohorts in the incidence of adverse events or adverse drug reactions related to study drug. Only 5 participants, all with decreased renal function, experienced a serious adverse event; none was recorded by investigators to be study drug-related. Among treated participants, children with decreased renal function who received a high dose of study drug had a significantly larger drop in diastolic blood pressure compared with children with normal renal function. These data show that antihypertensive treatment in children with renal dysfunction can be safe and efficacious, and consideration should be given to their inclusion in selected drug development programs.

    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.

    Full Text Available OBJECTIVES: There is a direct relationship between the regression of left ventricular hypertrophy (LVH and a decreased risk of mortality. This investigation aimed to describe the effects of anti-hypertensive drugs on cardiac hypertrophy through a meta-analysis of the literature. METHODS: The Medline (via PubMed, Lilacs and Scielo databases were searched using the subject keywords cardiac hypertrophy, antihypertensive and mortality. We aimed to analyze the effect of anti-hypertensive drugs on ventricle hypertrophy. RESULTS: The main drugs we described were enalapril, verapamil, nifedipine, indapamina, losartan, angiotensin-converting enzyme inhibitors and atenolol. These drugs are usually used in follow up programs, however, the studies we investigated used different protocols. Enalapril (angiotensin-converting enzyme inhibitor and verapamil (Ca++ channel blocker caused hypertrophy to regress in LVH rats. The effects of enalapril and nifedipine (Ca++ channel blocker were similar. Indapamina (diuretic had a stronger effect than enalapril, and losartan (angiotensin II receptor type 1 (AT1 receptor antagonist produced better results than atenolol (selective β1 receptor antagonist with respect to LVH regression. CONCLUSION: The anti-hypertensive drugs induced various degrees of hypertrophic regression.

    To establish the clinical relevance of drug interactions between nonsteroidal antiinflammatory drugs (NSAIDs) and antihypertensives, based on the interaction severity and probability of occurrence. Systematic review. A PubMed/Medline search was made using the MeSH terms: NSAIDs, Antihypertensive drugs, and Drug interactions. Articles between 2002 and 2012, human studies, in Spanish and English and full text access were included. Found articles were included and some of the references used in this works. Studies with in vitro methods, effects on ocular hypertension and those who do not consider the interaction NSAIDs, antihypertensives were excluded. For the selection of the papers included three independent reviewers were involved. We used a tool for data extraction and for assess of the interaction clinical relevance. Nineteen of 50 papers found were included. There were identified 21 interactions with pharmacodynamic mechanism, classified by their clinical relevance in level-2 high risk (76.2%) and level-3 medium risk (23.8%). In addition, evidence of 16 combinations of no interaction were found. Some NSAIDs may attenuate the effectiveness of antihypertensive drugs when used concurrently, especially with angiotensin converting enzyme inhibitors, diuretics, beta blockers and angiotensin receptorsii blockers. There was no evidence of effect modification of calcium channel antagonists, especially dihydropyridine, by concurrent use of NSAIDs. Copyright © 2013 Elsevier España, S.L.U. All rights reserved.

    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.

    The acute antihypertensive effects and possible underlying mechanisms of 3 beta-adrenergic-blocking drugs with alpha-blocking activity, i.e. labetalol, drugs with alpha-blocking activity, i.e. labetalol, nipradilol and arotinolol, were studied in conscious spontaneously hypertensive rats (SHR) and compared with the effects of prazosin, propranolol and hydralazine. Prazosin produced a dose-dependent antihypertensive effect which paralleled inhibition of the pressor response to phenylephrine. Labetalol (30 mg/kg), nipradilol (30 and 100 mg/kg) and arotinolol (30 and 100 mg/kg) also produced a fall in blood pressure. However, inhibition of the pressor response to phenylephrine was not seen in association with the antihypertensive effect after the lower dose of nipradilol and arotinolol. Propranolol (100 mg/kg) did not lower blood pressure. These results suggest that a mechanism(s) other than an alpha-adrenergic-blocking effect plays a role in the acute antihypertensive effects produced by the lower dose of nipradilol and arotinolol.

    Recent clinical reports have suggested that hypertension accelerates the progress of diabetic nephropathy and retinopathy, whereas antihypertensive treatments may retard them. Thus, the effect of antihypertensive treatment in diabetes mellitus with hypertension was evaluated in rats. A model of diabetes mellitus with hypertension has been developed in spontaneously hypertensive (SHR) rats by unilateral nephrectomy and streptozotocin (STZ, 30 mg/kg, i.v. treatment). The rats were treated with four antihypertensive drugs orally for 12 weeks thereafter. STZ treatment induced chronic hypeglycaemia (300-400 mg/dl), decreased body weight and heart rate, and caused vascular changes of ophthalmic fundi and cataracta. The kidney of these rats showed proliferative changes such as periarteritis nodosa, hyperplasia, or fibronecrosis of the arterioles, exudative changes, mesangial proliferation, or thickening of the basement membrane of the glomeruli. Enalapril (10 mg/kg per day) and remipril (Hoe 498) (1 mg/kg per day), converting enzyme inhibitors, or arotinolol (20 mg/kg per day), a beta-adrenoceptor blocking drug, decreased blood pressure, prevented the development of renal and ocular lesions, and tended to increase creatinine clearance. Nisoldipine (3 mg/kg per day), a calcium-entry blocking drug, tended to decrease blood glucose, and prevented the decrease of body weight and development of ocular lesions. In conclusion, antihypertensive treatments were effective in preventing the progress of diabetic retinopathy and nephropathy, and renal insufficiency in this animal model.

    This article is a report of a study to determine the effect of an educational programme and to follow up weekly meetings on nurses and medical resident's attitudes towards positive communication and collaboration. Clear and appropriate communication and interdisciplinary collaboration is critical to the delivery of quality care. Collaborative practice among all healthcare professionals creates a positive work environment, decreases costs, improves job satisfaction among nurses and improves patient care, as well as decreasing patient morbidity and mortality. Poor communication and lack of teamwork or collaboration have been cited as persistent problems in healthcare. The study was conducted in 2008 - 2009 at a hospital where a new medical residency programme was beginning and nurses had no prior experience working with medical residents. A quasi-experimental pre test, post-test design was used. The Jefferson Scale of Attitudes towards Physician-Nurse Collaboration and the Communication, Collaboration and Critical Thinking for Quality Patient Outcomes Survey tool measured the attitudes of 68 nurses and 47 medical residents in the areas of positive communication and collaboration. The study demonstrates that a formal educational programme and follow-up discussions improved the attitudes of both nurses and medical residents on the Jefferson scale (medical residents t = 4·68, P = 0·001, nurses t = 4·37, P = 0·001) and on the communication scale (medical residents t = 4·23, P = 0·001, nurses t = 4·13, P = 0·001). Continuing education for nurses, medical residents and other healthcare providers may assist in developing positive communication styles and promote collegiality and team work. © 2011 Blackwell Publishing Ltd.

    2011-02-01

    To investigate diabetic patients' perceptions of illness and treatments, and explore relationships to adherence and blood glucose control. Forty-nine type 1 and one hundred and eight type 2 diabetic patients completed questionnaires assessing illness perceptions, treatment beliefs, and adherence to medications, diet, and exercise. Blood glucose control was assessed from blood tests. Patients rated medication more important than diet and exercise, and reported higher adherence to medications. Insulin was perceived as more helpful for diabetes, while antihypertensives and cholesterol medication were perceived more helpful for preventing heart problems. Perceptions were associated with adherence to insulin, cholesterol and antihypertensive medications, exercise, and diet. Blood glucose control in type 1 diabetic patients was associated with insulin adherence and perceived personal control, and in type 2 diabetic patients to being prescribed insulin or antihypertensives, and perceived personal control. Patients hold specific mental models about diabetes treatments, which are associated with adherence.

    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.

    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.

    Antihypertensive medication represents one of the most common prescriptions for senior individuals. Numerous studies have assessed the influence of antihypertensive treatment on the risk for osteoporotic fracture, yet much controversy remains. We analyzed the relationship between the incidence of osteoporotic fracture and the average number of daily antihypertensive drugs (NDAD) included in the prescription of elderly hypertensive patients. The study population was derived from the National Health Insurance Service-Senior Cohort (2002-2013), and consisted of elderly patients (≥60 years) diagnosed with hypertension in 2009, who did not have osteoporotic fractures in 2008, and underwent at least one national health check-up between 2009 and 2013, and had complete records after 2010. The outcome measured was the incidence of osteoporotic fractures between 2010 and 2013. The study population was stratified into the three groups (low, moderate, and high), in terms of NDAD. A total of 137,304 hypertensive patients were included. A multivariate model corrected by age, gender, body mass index, systolic blood pressure, underlying disease, smoking status, and use of medicines showed that the groups with moderate and high NDAD exhibited, respectively, 12% and 16% lower risk of osteoporotic fracture compared to that in the group with low NDAD. In terms of the risk of osteoporotic fracture associated with the number of daily thiazide diuretics (NDTD), the adjusted odds ratios (aOR; 95%CI) were 0.89 (0.84-0.94) and 0.93 (0.84-1.02) in the groups with moderate and high NDTD, respectively compared to low NDTD as reference. As to NDADnotTD, the aOR (95%CI) were 0.90 (95%CI, 0.86-0.94) and 0.89 (95%CI, 0.84-0.95) in the groups with moderate and high NDADnotTD, respectively compared to low NDADnotTD as reference. In elderly hypertensive patients, the incidence of osteoporotic fracture decreased as the NDAD increased. The incidence rate of osteoporotic fracture also decreased with

    A randomized controlled trial was conducted in 2015 to evaluate a mobile continuing medical education (mCME) intervention that provided daily text messages to community-based physicians' assistants (CBPAs) in Thai Nguyen Province, Vietnam. Although the intervention failed to improve medical knowledge over a 6-month period, a companion qualitative study provided insights on the views and experiences of intervention participants. We conducted focus group discussions (FGDs) and in-depth interviews (IDIs) among participants randomized to receive text messages containing either simple medical facts or quiz questions. Trained interviewers collected data immediately following the conclusion of the trial in December 2015. Using semi-structured question guides, respondents were queried on their views of the intervention, positive and negative, and perceived impacts of the intervention. During analysis, after learning that the intervention had failed to increase knowledge among participants, we also examined reasons for lack of improvement in medical knowledge. All analyses were performed in NVivo using a thematic approach. A total of 70 CBPAs engaged in one of 8 FGDs or an IDI. One-half were men; average age among all respondents was 40 years. Most (81%) practiced in rural settings and most (51%) focused on general medicine. The mean length of work experience was 3 years. All respondents made positive comments about the intervention; convenience, relevance, and quick feedback (quiz format) were praised. Downsides encompassed lack of depth of information, weak interaction, technology challenges, and challenging/irrelevant messages. Respondents described perceived impacts encompassing increased motivation, knowledge, collegial discussions, Internet use to search for more information, and clinical skills. Overall, they expressed a desire for the intervention to continue and recommended expansion to other medical professionals. Overreliance on the text messages, lack of

    The purpose of this study was to compare the long-term clinical outcomes of patients with chronic total occlusion (CTO) and well-developed collateral circulation treated with revascularization versus medical therapy. Little is known about the clinical outcomes and optimal treatment strategies of CTO with well-developed collateral circulation. We screened 2,024 consecutive patients with at least 1 CTO detected on coronary angiogram. Of these, we analyzed data from 738 patients with Rentrop 3 grade collateral circulation who were treated with medical therapy alone (n = 236), coronary artery bypass grafting (n = 170) or percutaneous coronary intervention (n = 332; 80.1% successful). Patients who underwent revascularization and medical therapy (revascularization group, n = 502) were compared with those who underwent medical therapy alone (medication group, n = 236) in terms of cardiac death and major adverse cardiac events (MACE), defined as the composite of cardiac death, myocardial infarction, and repeat revascularization. During a median follow-up duration of 42 months, multivariate analysis revealed a significantly lower incidence of cardiac death (hazard ratio [HR]: 0.29; 95% confidence interval [CI]: 0.15 to 0.58; p collateral circulation, aggressive revascularization may reduce the risk of cardiac mortality and MACE.

    With increasing attendance and media attention, large-scale electronic dance music events (EDMEs) are a subset of mass gatherings that have a unique risk profile for attendees and promoters. Shambhala Music Festival (Canada) is a multi-day event in a rural setting with a recognized history of providing harm reduction (HR) services alongside medical care. Study/Objective This manuscript describes the medical response at a multi-day electronic music festival where on-site HR interventions and dedicated medical care are delivered as parallel public health measures. This study was a descriptive case report. Medical encounters and event-related data were documented prospectively using an established event registry database. In 2014, Shambhala Music Festival had 67,120 cumulative attendees over a 7-day period, with a peak daily attendance of 15,380 people. There were 1,393 patient encounters and the patient presentation rate (PPR) was 20.8 per one thousand. The majority of these (90.9%) were for non-urgent complaints. The ambulance transfer rate (ATR) was 0.194 per one thousand and 0.93% of patient encounters were transferred by ambulance. No patients required intubation and there were no fatalities. Harm reduction services included mobile outreach teams, distribution of educational materials, pill checking facilities, a dedicated women's space, and a "Sanctuary" area that provided non-medical peer support for overwhelmed guests. More than 10,000 encounters were recorded by mobile and booth-based preventive and educational services, and 2,786 pills were checked on-site with a seven percent discard rate. Dedicated medical and HR services represent two complementary public health strategies to minimize risk at a multi-day electronic music festival. The specific extent to which HR strategies reduce the need for medical care is not well understood. Incorporation of HR practices when planning on-site medical care has the potential to inform patient management, reduce

    We sought to describe pediatric cardiovascular medication errors and to determine patients and medications with more-frequently reported and/or more-harmful errors. We analyzed cardiovascular medication error reports from 2003-2004 for patients error, no harm; E-I, harmful error). Proportions of harmful reports were determined according to drug class and age group. "High-risk" drugs were defined as antiarrhythmics, antihypertensives, digoxin, and calcium channel blockers. A total of 147 facilities submitted 821 reports with community hospitals predominating (70%). Mean patient age was 4 years (median: 0.9 years). The most common error locations were NICUs, general care units, PICUs, pediatric units, and inpatient pharmacies. Drug administration, particularly improper dosing, was implicated most commonly. Severity analysis showed 5% "near misses," 91% errors without harm, and 4% harmful errors, with no reported fatalities. A total of 893 medications were cited in 821 reports. Diuretics were cited most frequently, followed by antihypertensives, angiotensin inhibitors, beta-adrenergic receptor blockers, digoxin, and calcium channel blockers. Calcium channel blockers, phosphodiesterase inhibitors, antiarrhythmics, and digoxin had the largest proportions of harmful events, although the values were not statistically significantly different from those for other drug classes. Infants medication errors reaching inpatients, in a national, voluntary, error-reporting database. Proportions of harmful errors were not significantly different by age or cardiovascular medication. Most errors were related to medication administration, largely due to improper dosing.

    Full Text Available Abstract Background Beta-blocker drugs are commonly used in family practice and studies showed that they were the most popularly prescribed medications among all antihypertensive agents. This study aimed to identify the factors associated with medication switching from a beta-blocker to another antihypertensive drug among Chinese patients. Methods We used a validated database which consisted of the demographic and clinical information of all Chinese patients prescribed a beta-blocker from any public, family practice clinics between 01 Jan 2004 to 30 June 2007 in one large Territory of Hong Kong. The proportion of patients switched from beta-blockers to another antihypertensive agent 180 days within their first prescription was studied, and the factors associated with medication switching were evaluated by using multivariate regression analyses. Results From 19,177 eligible subjects with a mean age of 59.1 years, 763 (4.0% were switched from their beta-blockers within 180 days of commencing therapy. A binary logistic regression model used medication switching as the outcome variable and controlled for age, gender, socioeconomic status, clinic setting (general out-patient clinics, family medicine specialist clinic or staff clinics, district of residence, visit type (new vs. follow-up attendance, the number of concomitant co-morbidities, and the calendar year of prescription. It was found that older patients (age 50-59 years: adjusted odds ratio [AOR] 1.38, 95% C.I. 1.12-1.70; p = 0.002; age 60-69 years: AOR 1.63 95% C.I. 1.30-2.04, p Conclusions Closer monitoring of the medication taking behavior among the older patients and the new clinic visitors prescribed a beta-blocker is warranted. Future studies should evaluate the reasons of drug switching.

    To assess a new Chinese insurance benefit with capitated provider payment for common diseases in outpatients. Longitudinal health insurance claims data, health administrative data and primary care facility data were used to assess trajectories in outpatient visits, inpatient admissions, expenditure per common disease outpatient (CD/OP) visit and prescribing indicators over time. We conducted segmented regression analyses of interrupted time series data to measure changes in level and trend overtime, and cross-sectional comparisons against external standards. The number of total outpatient visits at 46 primary care facilities (on the CD/OP benefit as of July 2012) increased by 46 895 visits/month (P = 0.004, 95% CI: 15 795-77 994); the average number of CD/OP visits reached 1.84/year/enrollee in 2012; monthly inpatient admissions dropped from 6.4 (2009) to 4.3 (2012) per 1000 enrollees; the median total expenditure per CD/OP visit dropped by CNY 15.40 (P = 0.16, 95% CI: -36.95~6.15); injectable use dropped by 7.38% (P = 0.03, 95% CI: -14.08%~-0.68%); antibiotic use was not improved. Zhuhai's new CD/OP benefit with capitated provider payment has expanded access to primary care, which may have led to a reduction in expensive specialist inpatient services for CD/OP benefit enrollees. Cost awareness was likely raised, and rapidly growing expenditures were contained. Although having been partially improved, inappropriate prescribing of antibiotics and injectables was still prevalent. More explicit incentives and specific quality of care targets must be incorporated into the capitated provider payment to promote scientifically sound and cost-effective care and treatment. © 2015 John Wiley & Sons Ltd.

    Objective: Involvement of all regional medical facilities in a trauma system is challenging in rural regions. We hypothesized that the physician-staffed helicopter emergency medical service potentially encouraged local facilities to participate in trauma systems by providing the transport of patients with trauma to those facilities in a rural setting. Materials and Methods: We performed two retrospective observational studies. First, yearly changes in the numbers of patients with trauma and destination facilities were surveyed using records from the Miyazaki physician-staffed helicopter emergency medical service from April 2012 to March 2014. Second, we obtained data from medical records regarding the mechanism of injury, severity of injury, resuscitative interventions performed within 24 h after admission, secondary transports owing to undertriage by attending physicians, and deaths resulting from potentially preventable causes. Data from patients transported to the designated trauma center and those transported to non-designated trauma centers in Miyazaki were compared. Results: In total, 524 patients were included. The number of patients transported to non-designated trauma centers and the number of non-designated trauma centers receiving patients increased after the second year. We surveyed 469 patient medical records (90%). There were 194 patients with major injuries (41%) and 104 patients with multiple injuries (22%), and 185 patients (39%) received resuscitative interventions. The designated trauma centers received many more patients with trauma (366 vs. 103), including many more patients with major injuries (47% vs. 21%, p service potentially encouraged non-designated trauma centers to participate in trauma systems while maintaining patient safety.

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

    Cynthia Blanton

    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

  9. An exploratory study of the potential learning benefits for medical students in collaborative drawing: creativity, reflection and ‘critical looking’

    Science.gov (United States)

    2013-01-01

    Background Building on a series of higher educational arts/medicine initiatives, an interdisciplinary drawing module themed on the human body was developed for both year 3 Craft students and year 3 Medicine degree students. This became the subject of a research project exploring how the collaborative approach to drawing adopted on this module impacted on the students’ learning. In this article, emphasis is given to issues thought to have most potential relevance to medical education. Methods Using an ethnographic research design, the methods adopted were: direct observation of all aspects of the module sessions, audio and video recordings and photographs of the sessions, the incorporation of a semi-structured discussion at the end of each session, and anonymous student questionnaires. Results A number of key themes emerged. The complex, phased and multi-sensory nature of the ‘critical looking’ skills developed through the drawing exercises was seen as of potential value in medical education, being proposed as analogous to processes involved in clinical examination and diagnosis. The experience of interdisciplinary collaborative drawing was significant to the students as a creative, participatory and responsive form of learning. The emphasis on the physical experience of drawing and the thematic use of the human body as drawing subject led to reflective discussions about bodily knowledge and understanding. There were indications that students had a meta-cognitive awareness of the learning shifts that had occurred and the sessions provoked constructive self-reflective explorations of pre-professional identity. Conclusions This preliminary study suggests, through the themes identified, that there may be potential learning outcomes for medical students in this model of interdisciplinary collaborative drawing of the human body. Further research is needed to explore their applicability and value to medical education. There is a need to explore in more depth the

    Blood pressure (BP) control rates and number of antihypertensive medications were compared (average follow-up 4.9 years) by randomized groups: chlorthalidone, 12.5-25 mg/d (n=15,255), amlodipine 2.5-10 mg/d (n=9,048), or lisinopril 10-40 mg/d (n=9,054) in a randomized double-blind hypertension trial. Participants were hypertensives age t55 with additional cardiovascular risk factor(s), recruited from 623 centers. Additional agents from other classes were added as needed to achieve BP control. BP was reduced from 145/83 mmHg (27% control) to 134/76 mmHg (chlorthalidone, 68% control), 135/75 mmHg (amlodipine, 66% control), and 136/76 mmHg (lisinopril, 61% control) by 5 years; the mean number of drugs prescribed was 1.9, 2.0, and 2.1, respectively. Only 28% (chlorthalidone), 24% (amlodipine), and 24% (lisinopril) were controlled on monotherapy. A majority achieved BP control in each randomized group--a greater proportion with chlorthalidone. Over time, providers and patients should expect multidrug therapy to achieve BP<140/90 mmHg in a majority of patients. PMID:19090876

    2018-02-01

    : Evidence from randomized trials has shown that effective treatment with blood pressure (BP)-lowering medications reduces the risk of cardiovascular morbidity and mortality in patients with hypertension. Therefore, hypertension control and prevention of subsequent morbidity and mortality should be achievable for all patients worldwide. However, many people in Latin America remain undiagnosed, untreated or have inadequately controlled BP, even where this is access to health systems. Barriers to hypertension control in low-income countries include difficulties in transportation to health services; inappropriate opening hours; difficulties in making clinic appointments; inaccessible healthcare facilities, lack of insurance and high treatment costs. After a review of the best recent available evidence on the efficacy and tolerability of antihypertensive drugs and strategies, the Latin American Society of Hypertension experts conclude that all major classes of BP-lowering drugs be available to hypertensive patients, because all have been shown to reduce major cardiovascular outcomes compared with placebo, and have shown to be associated with a comparable risk of major cardiovascular events and mortality when compared between classes. Within each class, no evidence whatsoever is available to show that one compound is more effective than another in outcome prevention. Therefore, the selection of individual drugs may be based mainly on the capacity of Latin American governments to obtain the lowest prices of the different molecules manufactured by companies with high production quality standards.

    Traditionally Thymus linearis Benth. have been used for treatment of various diseases including hypertension. The present study was conducted to evaluate the hypotensive and antihypertensive effect of aqueous methanolic extract of aerial parts of Thymus linearis Benth. in normotensive and hypertensive rats. Acute and subchronic studies were also conducted. The aqueous methanolic extract produced a significant decrease in SBP, DBP, MBP and heart rate of both normotensive and hypertensive rats. LDv, of the extract was found to be 3000 mg/kg. The extract also exhibited a reduction in serum ALT, AST, ALP, cholesterol, triglycerides and LDL levels, while a significant increase in HDL level was observed. It is conceivable therefore, that Thymus linearis Benth. contains certain active compound(s) that are possibly responsible for the observed antihypertensive activity. Moreover, these findings further authenticate the traditional use of this plant in folklore medicine.

    Proteins from tilapia frame and skin can potentially be precursors of antihypertensive peptides according to the result of BIOPEP analyses. The aim was to generate peptides with inhibitory effects against angiotensin-converting enzyme (ACE) and renin from tilapia frame and skin protein isolates (FPI and SPI). The most active hydrolysate was then tested for blood pressure-lowering ability in spontaneously hypertensive rats (SHRs). Tilapia frame and skin protein hydrolysates (FPHs and SPHs) were respectively produced from FPI and SPI hydrolysis using pepsin, papain, or bromelain. The ACE-inhibitory activities of tilapia protein hydrolysates with varying degree of hydrolysis (DH) were evaluated. In order to enhance the activity, the hydrolysate was fractionated into four fractions (tilapia processing coproducts may be valuable protein raw materials for producing antihypertensive peptides.

  17. Occurrence, ecotoxicological effects and risk assessment of antihypertensive pharmaceutical residues in the aquatic environment--A review.

    2015-11-01

    This study presents a review of the investigated antihypertensives in different aquatic compartments. It aims to compare these data with those regarding ecotoxicity effects in order to find out ecotoxicological data gaps for these pharmaceuticals and to point out the need for future studies. In addition, part of this article is dedicated to the risk assessment of the parent compounds atenolol, metoprolol, propranolol and verapamil, which are of great environmental concern in terms of contamination levels and for which there are sufficient ecotoxicological data available. 79 articles were retrieved presenting quantization data for 34 different antihypertensives and/or their metabolites. Only 43 articles were found regarding acute and chronic ecotoxicological effects of antihypertensive drugs. The results indicated that the beta-blockers atenolol, metoprolol and propranolol are the antihypertensives most frequently detected in the aquatic environment. They are also the drugs which reached the highest maximum concentrations in surface waters in the data reported in the literature. The highest percentages of ecotoxicity data regarding antihypertensives were also related to these beta-blockers. On the other hand, there is clearly a lack of ecotoxicity data, especially the chronic ones, regarding other antihypertensives. The environmental risk assessment (ERA) showed that all three of the evaluated beta-blockers can pose a potential long-term risk for non-target organisms of both fresh and marine water species. However, more meaningful ecotoxicity data for antihypertensives, including saltwater species, are required to refine and enlarge these results. Additional studies focusing on potential interactions between pharmaceutical mixtures, including antihypertensives, are also an urgent need. Copyright © 2015 Elsevier Ltd. All rights reserved.

    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.

    Flos Chrysanthemi is used in a variety of diseases in traditional Chinese medicine including hypertension, and the total flavonoids (rich in luteolin (LUT) and buddleoside (BUD)) of Flos Chrysanthemi is known to modulate vascular functions and reduce the blood pressure. However, the active flavonoids and their synergistic effects on anti-hypertension are still unclear. To investigate the combined anti-hypertension effects of LUT and BUD enriched extracts on spontaneously hypertensive rats (SHR), as well as the anti-hypertensive mechanism of LUT&BUD mixture. CODA Mouse & Rat Tail-Cuff Blood Pressure System was used to measure the systolic blood pressure (SBP) and diastolic blood pressure (DBP) of SHR after treated with extracts contains with LUT and/or BUD. The expressions of Ang II, PRA, ALD, ET, PGI2 and TXB2 were investigated by ELASA. Serum NO concentration was measured by the method of Nitric acid reductase. A single administration of LUT, BUD, or LUT:BUD=1:1 significantly reduced SBP by about 3.35 mmHg, 4.39 mmHg and 15.42 mmHg, respectively. Chronic administration of LBM (at 60 mg/kg; p.o. for 30 days) reduced both SBP and DBP by 4.04% and 5.24% of the vehicle group, respectively. Oral administration of LBM at 60 mg/kg inhibited the serum levels of ANG, ALD and ET, but increased serum NO concentration. This study shows the synergistic anti-hypertension effects of LUT and BUD in SHR. The effects of LBM on blood pressure are associated with RAAS and endothelial system. Thus, our experiments suggest that the combination of luteolin and buddleoside from Flos Chrysanthemi are potentially useful for the therapeutic treatments for hypertension. © 2013 Elsevier Ireland Ltd.

    2011-01-01

    Probenecid has long been used in the treatment of gout. Its anti-gout mechanisms consist of uric acid reuptake inhibition and the consequent facilitation of uric acid excretion. In the present study, we investigated whether probenecid could exert an anti-hypertensive effect in spontaneously hypertensive rats (SHR). The noninvasive indirect tail cuff method was employed to measure blood pressure and heart rate. The administration of probenecid (50 mg/kg, ip) induced a significant systolic blood pressure (SBP) decrease, from 167 mmHg to 141 mmHg, within 120 min. In contrast, probenecid had little effect on normotensive control Wistar Kyoto rats (WKY). The anti-hypertensive effects of probenecid are almost as potent as those of atenolol. In a further exploration of the anti-hypertensive mechanisms of probenecid, its effects on phenylephrine-induced blood vessel contraction were tested. Our results suggest that probenecid significantly inhibited the contractions of rat aorta. This effect was also observed with endothelium-removed rat aorta, suggesting that probenecid can directly interact with the α-adrenergic receptor. Moreover, probenecid inhibited the α-adrenergic-receptor-mediated activation of ERK I/II in MC3TC-E1 cells. Therefore, our results indicate that probenecid might alleviate high blood pressure in SHR via inhibition of the α-adrenergic receptor and ERK I/II.

    Colocasia esculenta Linn (CE) is traditionally used for the treatment of various ailments such as high blood pressure, rheumatic pain, pulmonary congestion, etc. Hence in present study, the effect of aqueous extract of CE leaves (AECE) was evaluated for antihypertensive and acute diuretic activity in rats. Preliminary phytochemical evaluation revealed the presence of carbohydrate, saponins, tannins, and flavonoids in AECE. The animals did not show any sign of toxicity and mortality after the administration of AECE 2000 mg/Kg in acute oral toxicity study. The administration of AECE (100, 200, and 400 mg/Kg/day, p.o.) for six weeks and AECE (10, 20, and 40 mg/Kg, IV) on the day of experiment in renal artery-occluded hypertensive rats and AECE (20 and 40 mg/Kg, IV) in noradrenalin-induced hypertension in rats produced significant (p < 0.05) anti-hypertensive effects. AECE (400 mg/Kg, p.o.) showed positive diuretic activity at 5 h. AECE (200 and 400 mg/Kg, p.o.) significantly increased sodium and chloride content of urine in 5 h and 24 h and additionally potassium in 24 h urine. Hence, the results of the present study revealed the antihypertensive and weak diuretic activity of AECE. These effects may be attributed due to the ACE inhibitory, vasodilatory, β-blocking, and/ or Ca(2+) channel blocking activities, which were reported for the phytoconstitunts, specifically flavonoids such as vitexin, isovitexin, orientin, and isoorientin present in the leaves of CE.

    Previous studies have demonstrated the anti-hypertensive effects of Hibiscus sabdariffa L. (HS) in both humans and experimental animals. To explore the mechanisms of the anti-hypertensive effect of the HS, we examined the effects of a crude methanolic extract of the calyces of HS (HSE) on vascular reactivity in isolated aortas from spontaneously hypertensive rats. HSE relaxed, concentration-dependently, KCl (high K(+), 80 mM)- and phenylephrine (PE, 1 microM)-pre-contracted aortic rings, with a greater potency against the alpha(1)-adrenergic receptor agonist. The relaxant effect of HSE was partly dependent on the presence of a functional endothelium as the action was significantly reduced in endothelium-denuded aortic rings. Pretreatment with atropine (1 microM), L-NAME (10 microM) or methylene blue (10 microM), but not indomethacin (10 microM), significantly blocked the relaxant effects of HSE. Endothelium-dependent and -independent relaxations induced by acetylcholine and sodium nitroprusside, respectively, were significantly enhanced in aortic rings pretreated with HSE when compared to those observed in control aortic rings. The present results demonstrated that HSE has a vasodilator effect in the isolated aortic rings of hypertensive rats. These effects are probably mediated through the endothelium-derived nitric oxide-cGMP-relaxant pathway and inhibition of calcium (Ca(2+))-influx into vascular smooth muscle cells. The present data further supports previous in vivo findings and the traditional use of HS as an anti-hypertensive agent.

    Full Text Available We have previously demonstrated that acacia polyphenol (AP exerts strong anti-obesity, anti-diabetic, and anti-atopic dermatitis effects. In the present study, we investigated the anti-hypertensive effects of AP. Spontaneously hypertensive rats (SHR with hypertension and control Wistar Kyoto rats (WKY were used. WKY and SHR were fed AP-containing food or AP-free food (control group ad libitum for 4 weeks, and their blood pressures were measured. After AP administration, both systolic and diastolic blood pressures were significantly lower in the SHR group than in the control group. There were no differences in the systolic or diastolic blood pressure of WKY between the AP group and the control group. Angiotensin-converting enzyme (ACE activity, nicotinamide adenine dinucleotide phosphate (NADPH oxidase expression, and superoxide dismutase (SOD activity in SHR kidneys were not altered by AP administration. Blood SOD activity in SHR was significantly higher in the AP group than in the control group. AP exerts anti-hypertensive effects on hypertension but has almost no effect on normal blood pressure. The anti-hypertensive effects of AP may be related to the anti-oxidative effects of increased blood SOD activity.

    2013-01-01

    Abstract This study investigated the effects of different celery (Apium graveolens) seed extracts on blood pressure (BP) in normotensive and deoxycorticosterone acetate–induced hypertensive rats. The hexanic, methanolic, and aqueous-ethanolic extracts were administered intraperitoneally and their effects on BP and heart rate (HR) were evaluated in comparison with spirnolactone as a diuretic and positive control. Also, the amount of n-butylphthalide (NBP), as an antihypertensive constituent, in each extract was determined by HPLC. The results indicated that all extracts decreased BP and increased the HR in hypertensive rats, but had no effect on normotensive rats. The data showed that administration of 300 mg/kg of hexanic, methanolic, and aqueous-ethanolic (20/80, v/v) extracts of the celery seed caused 38, 24, and 23 mmHg reduction in BP and 60, 25, and 27 beats per minute increase in the HR, respectively. Also, the HPLC analysis data revealed that the content of NBP in the hexanic extract was 3.7 and 4 times greater than methanolic and aqueous-ethanolic extracts. It can be concluded that celery seed extracts have antihypertensive properties, which appears to be attributable to the actions of its active hydrophobic constitutes such as NBP and can be considered as an antihypertensive agent in chronic treatment of elevated BP.

    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/Aims: Arterial hypertension is characterized by vascular remodelling, atherosclerosis and cardiovascular complications. Matrix metalloproteases (MPPs are endopeptidases produced by all the cells present in the vascular wall and are involved in the regulation of the extracellular matrix protein turnover. MMPs contribute to blood vessel formation, remodelling, angiogenesis; whereas an altered expression or activity of MMPs or their tissue inhibitors (TIMPs results correlated with the development and progression of cardiovascular complications. Methods: We examined the literature data regarding the role of MMPs in human hypertension, including their involvement in vascular remodelling, and the effects of some antihypertensive molecules on these MMP/TIMP profile. Results: The expression and the activity of some MMPs and TIMPs are impaired in human hypertension. An altered MMPs/TIMPs balance plays an important role in the vascular wall rearrangement, in response to hemodynamic changes which may induce myocardial hypertrophy and fibrosis leading to ventricular remodelling. Several studies have examined the effects of some antihypertensive molecules, such as ACE inhibitors, angiotensin receptor blockers, calcium-channel blockers, and aldosterone antagonists, on the MMPs/TIMPs profile by obtaining positive results. Conclusion: Considering the data taken into consideration, the authors believe that in clinical practice a strategic antihypertensive therapy directed to the MMPs profile, may be useful to decrease the risk of cardiovascular complications.

    2016-01-01

    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.

    2014-03-01

    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.

    After recent revised grading by the US Preventive Services Task Force of mammography (MMG) recommendations for women in their 40s, it is urgent to collect data on the benefits and harm of MMG screenings in Japan. In this paper, we study the actual status and effectiveness of opportunistic breast cancer screening by MMG for women in their 40s. From January to December 2008, the total number of opportunistic breast cancer screenings by MMG at our institute was 12823. Of them, 398 (3.1 %) who were diagnosed as category 3 or more on MMG required further exams. The data were compared between two groups (women in their 40s, women aged 50 and older). Recall rate, detection rate of breast cancers, and implementation rate of further exams were evaluated. Recall rate was 4.0 % (166/4138) for women in their 40s and 2.4 % (166/6949) for women aged 50 and older. Detection rate of breast cancers was higher in women in their 40s (0.56 %) than women aged 50 and older (0.26 %). Non-cancer rate among women receiving invasive examination was higher in women in their 40s (0.76 %) than women aged 50 and older (0.42 %) (p = 0.02). The number of false positives required to detect one true cancer patient was smaller in women in their 40s (4.5) than women aged 50 and older (5.3). The results from our single institute revealed that opportunistic breast cancer screening by MMG for women in their 40s shows higher net benefits than for women aged 50 and older.

    In recent years, education and training in global health has been the subject of recurring debate in many countries. However, in Germany, there has been no analysis of the educational needs or demands of medical students, or the educational deficits or potential benefits involved in global health education. Our purpose is to analyse international health elective patterns of medical students enrolled at German universities and assess whether or how they prepare for their electives abroad. We examine the exposure of medical students enrolled at German universities to training courses in tropical medicine or global health and assess students' perceived needs and demands for education in global health. Cross-sectional study among medical students in Germany including all 36 medical schools during the second half of the year 2007. All registered medical students were eligible to participate in the study. Recruitment occurred via electronic mailing-lists of students' unions. We developed a web-based, semi-structured questionnaire to capture students' international mobility patterns, preparation before electives, destination countries, exposure to and demand for global health learning opportunities. 1126 online-replies were received and analysed from all registered medical students in Germany (N = 78.067). 33.0% of all respondents (370/1126) declared at least one international health elective and of these, 36.0% (133/370) completed their electives in developing countries. 36.0% (131/363) did not prepare specifically at all, 59.0% (214/363) prepared either by self-study or declared a participation in specific preparation programmes. 87.8% of 5th and 6th year students had never participated in a global health course and 72.6% (209/288) had not completed a course in tropical medicine. 94.0% (861/916) endorsed the idea of introducing global health into medical education. Students in our sample are highly mobile during their studies. International health electives are common

    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.

    2018-01-01

    Full Text Available This policy research aims to map patient access barriers to biologic treatments, to explore how increased uptake of biosimilars may lower these hurdles and to identify factors limiting the increased utilisation of biosimilars. A policy survey was developed to review these questions in 10 Central and Eastern European (CEE and Commonwealth of Independent States (CIS countries. Two experts (one public and one private sector representative from each country completed the survey. Questions were related to patient access, purchasing, clinical practice, and real-world data collection on both original biologics and biosimilars. Restrictions on the number of patients that can be treated and related waiting lists were reported as key patient access barriers. According to respondents, for both clinicians and payers the primary benefit of switching patients to biosimilars would be to treat more patients. However, concerns with therapeutic equivalence and fear of immunogenicity may reduce utilisation of biosimilars. Similar limitations in patient access to both original biologics and biosimilars raise concerns about the appropriateness and success of current biosimilar policies in CEE and CIS countries. The conceptual framework for additional real-world data collection exists in all countries which may provide a basis for future risk-management activities including vigorous pharmacovigilance data collection.

    Full Text Available Objective. To assess the effects of bariatric surgery versus medical therapy for type 2 diabetes mellitus. Methods. The Cochrane library, PubMed, Embase, Chinese biomedical literature database, and Wanfang database up to February 2012 were searched. The literature searches strategies contained terms (“diabetes*”, “surg*”, and “medic*” were used, combined with the medical subject headings. Randomized controlled trails (RCTs of frequently used bariatric surgery for obese patients with type 2 diabetes were included. Study selection, data extraction, quality assessment, and data analyses were performed according to the Cochrane standards. Results. Three randomized controlled trials (RCTs involving 170 patients in the bariatric surgery groups and 100 patients in the medical therapy group were selected. Compared with medical therapy, bariatric surgery for type 2 diabetes can significantly decrease the levels of HbA1c, FBG, weight, triglycerides, and the dose of hypoglycemic, antihypertensive, and lipid-lowering medicine, while increasing the rate of diabetes remission (RR = 9.74, 95%CI, (1.36, 69.66 and the levels of high-density lipoprotein. However, there are no statistical differences in serious adverse events between the surgical and medical groups (RR = 1.23, 95%CI, (0.80, 1.87. Conclusions. Surgical procedures were more likely to help patients achieve benefits than medical therapy alone. Further intensive RCTs of high-quality, multiple centers and long-term followup should be carried out to provide more reliable evidence.

    Thiazide-type diuretics have been recommended for initial treatment of hypertension in most patients, but should this recommendation differ for patients with and without coronary heart disease (CHD)? The Antihypertensive and Lipid-Lowering Treatment to Prevent Heart Attack Trial (ALLHAT) was a randomized, double-blind hypertension treatment trial in 42,418 participants with high risk of combined cardiovascular disease (CVD) (25% with preexisting CHD). This post hoc analysis compares long-term major clinical outcomes in those assigned amlodipine (n = 9048) or lisinopril (n = 9,054) with those assigned chlorthalidone (n = 15,255), stratified by CHD status. After 4 to 8 years, randomized treatment was discontinued. Total follow-up (active treatment + passive surveillance using national databases for deaths and hospitalizations) was 8 to 13 years. For most CVD outcomes, end-stage renal disease, and total mortality, there were no differences across randomized treatment arms regardless of baseline CHD status. In-trial rates of CVD were significantly higher for lisinopril compared with chlorthalidone, and rates of heart failure were significantly higher for amlodipine compared with chlorthalidone in those with and without CHD (overall hazard ratios [HRs] 1.10, p heart failure in amlodipine compared with chlorthalidone (HR 1.12; p = 0.01) during extended follow-up did not differ by baseline CHD status. In conclusion, these results provide no reason to alter our previous recommendation to include a properly dosed diuretic (such as chlorthalidone 12.5 to 25 mg/day) in the initial antihypertensive regimen for most hypertensive patients.

    The aim of this study was to evaluate the impact of telehealth on 1) the diagnosis, and management in obstetrics and cardiology, 2) health care costs from patients' perspectives, 3) attendance at health centres located in remote areas of Mali. The impact of telehealth on health care utilization, quality, and costs was assessed using a five-point Likert-scale based questionnaire consisting of three dimensions. It was completed by health care professionals in four district hospitals. The role of telehealth on attendance at health centres was also assessed based on data collected from the consultations logs before and during the project, between project sites and control sites. Referrals specific to the activities of the research study were also evaluated using a questionnaire to measure the real share of telehealth tools in increasing attendance at project sites. Finally, the cost savings achieved was estimated using the transport and lodging costs incurred if patients were to travel to the capital city for the same tests or care. The telehealth activities contributed to improving medical diagnoses in cardiology and obstetrics (92.6%) and the patients' management system on site (96.2%). The attendance records at health centres increased from 8 to 35% at all project sites during the study period. Patients from project sites saved an average of 12380 XOF (CFA Francs) or 25 USD (American dollar) and a maximum of 35000 XOF or 70 USD compared to patients from neighbouring sites, who must go to the capital city to receive the same care. We conclude that in Mali, enhanced training in ultrasound / electrocardiography and the introduction of telehealth have improved the health system in remote areas and resulted in high levels of appropriate diagnosis and patient management in the areas of obstetrics and cardiology. Telehealth can also significantly reduce the cost to the patient.

    Extracts of olive leaf, green coffee bean and beetroot may deliver cardiovascular benefits. This study sought to evaluate the effects of regularly consuming a combination of these extracts on blood pressure (BP), arterial compliance, blood lipids, blood glucose and insulin sensitivity. A double-blind randomised placebo-controlled crossover trial was conducted in adults with untreated high normal or borderline elevated BP. They were randomised to take an active supplement, comprising 500 mg olive leaf extract, 100 mg green coffee bean extract and 150 mg beet powder, or a matching placebo twice daily for six weeks, followed by the alternate supplement for a further six weeks. Assessments of 24-h ambulatory BP (ABP), clinic BP arterial compliance (pulse-wave analysis), blood lipids, blood glucose and insulin were obtained at baseline and at the end of each treatment phase. Baseline clinic BP in 37 overweight middle-aged men and women who completed the trial averaged 145/84 mmHg. There was no significant effect of treatment on ABP or any other outcome measure. The failure to confirm prior evidence of the antihypertensive benefits of these extracts emphasises the importance of placebo control and the value of ABP monitoring. Further dose-response evaluation of olive leaf, green coffee bean or beetroot extracts is required to confirm or refute the purported benefits.

To study antihypertensive efficacy and safety of valsartan (Diovan, Novartis Pharma as well as patient’s compliance to the mono- or combined valsartan based therapy in smoking vs non-smoking hypertensive patients.Material and methods. It was a prospective multicenter observation study. 114 doctors from 81 medical institutions of Russia participated in the study. 650 hypertensive patients (41,2% of smokers and 58,8% of non-smokers; age 53,9±0,4 y.o. in average were included in the study. The evaluation of therapy efficacy was based on analysis of systolic (SBP and diastolic (DBP blood pressure (BP changes and of patient number who answered to the treatment and reached BP target level. Safety and compliance of the treatment also was analyzed. The initial valsartan dose was 80 mg OD and may be increased (up to 320 mg OD by doctor for achievement of BP target level. A combination of the valsartan with hydrochlorothiazide was also allowed. Amlodipine (5-10 mg/d or any other antihypertensive also may be added if necessary.Results. Significant decrease of SBP and DBP was observed in each group between the 1st and 5th visits. SBP decreased by 37,5 mm Hg (р<0,01 in smoking patients and by 37,6 mm Hg (р<0,01 in non-smoking ones. DBP decreased by 18,5 mm Hg (р<0,01 in smoking patients and by 15,9 mm Hg (р<0,01 in non-smoking ones. Differences in SBP and DBP changes were not significant between groups. Target BP level (<140/90 mm Hg was reached in 96,2% of smokers and in 96% of non-smokers. 99% of smoking patients and 96,1% of non-smoking ones responded to valsartan based therapy according to defined criteria.Conclusion. Similar antihypertensive efficacy and safety of valsartan mono- and combined therapy was found out in smoking and non-smoking hypertensive patients.

    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.

  2. Self-medication among people living with hypertension: a review.

    Science.gov (United States)

    Rahmawati, Riana; Bajorek, Beata V

    2017-04-01

    Self-medication is commonly practised by patients, underpinned by health beliefs that affect their adherence to medication regimens, and impacting on treatment outcomes. This review explores the scope of self-medication practices among people with hypertension, in terms of the scale of use, types of medication and influencing factors. A comprehensive search of English language, peer-reviewed literature published between 2000 and 2014 was performed. Twenty-seven studies met the inclusion criteria; 22 of these focused on complementary and alternative medicines (CAMs). Anti-hypertensive medications are listed among the 11% of products that patients reportedly obtain over-the-counter (OTC) for self-medication. On average, 25% of patients use CAMs, mostly herbs, to lower blood pressure. Recommendations by family, friends and neighbours are the most influential factors for self-medication with CAMs. Faith in treatment with CAMs, dissatisfaction with conventional medicine and the desire to reduce medication costs are also cited. Most (70%) patients with hypertension take OTC medicines to treat minor illnesses. The concurrent use of anti-hypertensive medications with analgesics and herbal medicines is commonly practised. The sociodemographic profile of patients engaging in self-medication differs markedly in the articles reviewed; self-medication practices cannot be attributed to a particular profile. Low disclosure of self-medication is consistently reported. This review highlights a high proportion of people with hypertension practise self-medication. Further studies are needed to assess the impact of self-medication with OTC and anti-hypertensive medications on hypertension treatment. Health professionals involved in hypertension management should be mindful of any types of self-medication practices. © The Author 2017. Published by Oxford University Press. All rights reserved.

    The aims of this study were to evaluate the antihypertensive effects of the standardised methanolic extract of Carica papaya, its angiotensin converting enzyme inhibitory effects in vivo, its effect on the baroreflex and serum angiotensin converting enzyme activity, and its chemical composition. The chemical composition of the methanolic extract of C. papaya was evaluated by liquid chromatography-mass/mass and mass/mass spectrometry. The angiotensin converting enzyme inhibitory effect was evaluated in vivo by Ang I administration. The antihypertensive assay was performed in spontaneously hypertensive rats and Wistar rats that were treated with enalapril (10 mg/kg), the methanolic extract of C. papaya (100 mg/kg; twice a day), or vehicle for 30 days. The baroreflex was evaluated through the use of sodium nitroprusside and phenylephrine. Angiotensin converting enzyme activity was measured by ELISA, and cardiac hypertrophy was evaluated by morphometric analysis. The methanolic extract of C. papaya was standardised in ferulic acid (203.41 ± 0.02 µg/g), caffeic acid (172.60 ± 0.02 µg/g), gallic acid (145.70 ± 0.02 µg/g), and quercetin (47.11 ± 0.03 µg/g). The flavonoids quercetin, rutin, nicotiflorin, clitorin, and manghaslin were identified in a fraction of the extract. The methanolic extract of C. papaya elicited angiotensin converting enzyme inhibitory activity. The antihypertensive effects elicited by the methanolic extract of C. papaya were similar to those of enalapril, and the baroreflex sensitivity was normalised in treated spontaneously hypertensive rats. Plasma angiotensin converting enzyme activity and cardiac hypertrophy were also reduced to levels comparable to the enalapril-treated group. These results may be associated with the chemical composition of the methanolic extract of C. papaya, and are the first step into the development of a new phytotherapic product which could be used in the treatment of hypertension.

    To identify novel genes influencing blood pressure response to thiazide diuretic therapy for hypertension, we conducted genome-wide association meta-analyses of ≈1.1 million single nucleotide polymorphisms in a combined sample of 424 European Americans with primary hypertension treated with hydrochlorothiazide from the Pharmacogenomic Evaluation of Antihypertensive Responses Study (N=228) and the Genetic Epidemiology of Responses to Antihypertensive Study (N=196). Polymorphisms associated with blood pressure response at phydrochlorothiazide-treated European hypertensives. The rs16960228 polymorphism in protein kinase C, alpha replicated for same-direction association with diastolic blood pressure response in the Nordic Diltiazem Study (N=420) and the Genetics of Drug Responsiveness in Essential Hypertension Study (N=206), and the combined four-study meta-analysis p-value achieved genome-wide significance (p=3.3 × 10-8). Systolic/diastolic blood pressure responses were consistently greater in carriers of the rs16960228 A allele than in GG homozygotes (4/4 mmHg greater) across study samples. The rs2273359 polymorphism in the GNAS-EDN3 region also replicated for same-direction association with systolic blood pressure response in the Nordic Diltiazem Study, and the combined three-study meta-analysis p-value approached genome-wide significance (p=5.5 × 10-8). The findings document clinically-important effects of genetic variation at novel loci on blood pressure response to a thiazide diuretic, which may be a basis for individualization of antihypertensive drug therapy and identification of new drug targets.

    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

    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.

    Hypertension is one of the most common diseases in worldwide, thus prevention of hypertension is important in reducing the risks of cardiovascular disease. Milk contains bioactive peptides released during milk fermentation which lead to exhibit angiotensin I converting enzyme (ACE) inhibitory. The aim of this study was to investigate the antihypertensive effect of fermented skim camel milk on rats and compared with unfermented skim camel milk as control. The antihypertensive effect of fermented skim camel milk on thirty six male spontaneously hypertensive rats (SHR) was carried out for (short-term) and (long-term) using different doses (80, 240 and 1200 mg/kg body weight). Angiotensin converting enzyme (ACE) activity was also measured using ACE Kit. The blood pressure (systolic and diastolic) of spontaneously hypertensive rats (SHR) in short term administration (24 hours) of 1200 mg/kg body weight fermented skim camel milk decreased significantly (p camel milk for long-term (20 days) decreased and affected the heart rate (beats/min). The lowest record of systolic (41 mmHg) and diastolic blood pressure (19 mmHg) were at dose of 1200 mg/kg body weight of fermented skim camel milk at 15 days of administration. Likewise, ACE activity in plasma of SHR administered fermented skim camel milk decreased significantly (p camel milk by L. helveticus and S. thermophillus in SHR rats depends on the high dose of fermented skim camel milk in short and long-term. The ACE activity inhibitory was clear with fermented skim camel milk.

    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.

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.

    It is well known that some anti-hypertensive drugs affect insulin sensitivity and that tumor necrosis factor-alpha (TNF-alpha) is a mediator of obesity-associated insulin resistance. In this study, we have investigated the effect of anti-hypertensive drugs, calcium (Ca) channel blockers (amlodipine, manidipine and nicardipine), an alpha(1)-blocker (doxazosin), a beta(1)-blocker (metoprolol), and a thiazide diuretic (hydrochlorothiazide), on lipopolysaccharide (LPS)-induced TNF-alpha production. TNF-alpha production, measured with a bioassay and an immunoassay, was evaluated both in vivo and in vitro, by utilizing mice and a human peripheral blood mononuclear cell culture, respectively. Nicardipine, or amlodipine, manidipine and doxazosin significantly inhibited TNF-alpha production in mice at doses more than one or ten times higher than those used clinically, respectively. On the other hand, metoprolol increased TNF-alpha production at doses of more than 10 times those used clinically, whereas hydrochlorothiazide did not alter production of the cytokine. The in vivo effects of these drugs were not necessary parallel to the in vitro effects. Because high doses of these drugs in mice correspond to clinical doses and effects in human, these actions may be related to beneficial and/or harmful effects of these drugs on TNF-alpha mediated diseases, including insulin resistance.

    The financial burden for EU health systems associated with cardiovascular disease (CV) has been estimated to be nearly €110 billion in 2006, corresponding to 10% of total healthcare expenditure across EU or a mean €223 annual cost per capita. The main purpose of this study is to estimate the costs related to hypertension and the economic impact of increasing adherence to anti-hypertensive therapy in five European countries (Italy, Germany, France, Spain and England). A probabilistic prevalence-based decision tree model was developed to estimate the direct costs of CV related to hypertension (CV defined as: stroke, heart attack, heart failure) in five European countries. Our model considered adherence to hypertension treatment as a main driver of blood pressure (BP) control (BP euro>51.3 billion (8.1 in Italy, 17.1 in Germany, 12.2 in Spain, 8.8 in France and 5.0 in England). Increasing adherence to anti-hypertensive therapy to 70% would save a total of euro>332 million (CI 95%: €319-346 million) from the NPs perspective. This study is the first attempt to estimate the economic impact of non-adherence amongst patients with diagnosed hypertension in Europe, using data from five European countries (Italy, France, Germany, Spain and England).

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.

    To identify the sociodemographic and clinical profile of hypertensive patients who are not compliant with their antihypertensive treatment. each cardiologist described his or her next 4 hypertensive patients from a clinical standpoint and gave them a self-administered compliance questionnaire developed by the French Committee to Fight Hypertension, which they returned directly to the analysis center using a postage-paid reply envelope. 1965 patients 63.9 +/- 12.1 years old, 55.3% of whom were male, were included in the study. According to the specific questionnaire, compliance is definitely satisfactory in 35.9% of patients, is probably satisfactory in 28.3%, is probably poor in 19.4% and is definitely poor in 16.4%. Poor compliance is more frequent among men (38.1 vs. 33.4%; p age (51.6 vs. 34.1%; p age 55 on patient compliance. patients with the highest CV risk are those who are the least compliant with their antihypertensive treatment. These results raise the question of the appropriateness of the prevention information given to the most at-risk patients.

    The present study was performed to evaluate the cardiovascular effects of ethanolic extract from the root bark of Ulmus macrocarpa (RBUM) in rats. The effects of RBUM on the vascular response of isolated rat aorta and the blood pressure of spontaneously hypertensive rats (SHRs) were evaluated. In addition, its antioxidant activity in H9c2 cells was investigated. In the free radical scavenging assay using 1,1-diphenyl-2-picrylhydrazyl stable free radical (DPPH), RBUM exhibited significant scavenging activity with an EC50 value of 14.3 microg/ml. RBUM also induced resistance to hydrogen peroxide-mediated oxidative insult in H9c2 myocardial cells. In isolated rat aortic preparations, RBUM exhibited potent vascular relaxant effect with an EC50 value of 1.9 microg/ml. This relaxation was significantly inhibited by denudation of the endothelial layer, pretreatment with NG-nitro-L-arginine methyl ester (10 microM), raising extracellular K+ (45 mM), and pretreatment with tetraethylammonium (10 mM). In an antihypertensive study with SHRs, long-term administration with RBUM (100 mg/kg) for 42 d decreased systolic blood pressure (approximately 20 mmHg). In SHRs after 42 d of treatment, RBUM recovered aortic relaxation to acetylcholine and sodium nitroprusside, and attenuated lipid peroxidation in liver of SHRs. These results suggest that chronic treatment with RBUM exerts antihypertensive effects in SHRs, and its direct vasorelaxant and antioxidant properties may contribute to reduce elevated blood pressure.

    The sympatholytic and norepinephrine depleting drug 1-methyl-3-keto-4-phenylquinuclidinium bromide (MA540) possessed significant chronic antihypertensive activity in mecamylamine- and renal-hypertensive dogs. The compound was approximately four times more potent than guanethidine in the former model and three times as potent in the latter. MA540 reduced orthostatic blood pressure responses in unanesthetized rabbits, but was approximately ten times less potent than guanethidine. The quinuclidine derivative did not affect cardiac output, heart rate or stroke volume in anesthetized open chest dogs and moderately increased mean blood pressure and total peripheral resistance. It produced diuresis and saluresis in anesthetized dogs, but did not influence water or electrolyte urinary excretion in conscious rats. In the latter test, guanethidine produced antidiuresis and antisaluresis. It was concluded that MA540 is a potent, orally effective antihypertensive agent acting through adrenergic neuron blockade, that it lacks undesirable effects on cardiac and renal functions, and that compared with guanethidine, it is more potent in lowering blood pressure but less so in interfering with orthostatic cardiovascular reflexes.

    Changing the blood pressure brings counter-regulatory effects into play which may impair the antihypertensive efficacy of treatment targeted at a single blood pressure regulatory factor. Thus, diuretics stimulate the renin angiotensin and catecholamine systems and, in some cases, vasopressin. Arteriolar vasodilators stimulate the sympathetic nervous system and renin-angiotensin system, while blockade of the renin-angiotensin system itself triggers a reactive release of renin which may then serve to restore normal circulating angiotensin II levels. Rational combinations can therefore be developed to neutralize the effects of counter-regulation and achieve blood pressure control at lower drug doses and hence with fewer side-effects. Such combinations can also be prescribed in steadily increasing doses of each drug, to achieve blood pressure control by a process of 3-stage titration. The stringent rules governing the clinical development of such combinations are reviewed: formulation, pharmacokinetics, pilot studies, factorial design, high-risk patients. One advantage of combination therapy is that it enhances compliance, as an entire treatment is contained in a single pack of drugs. A disadvantage is the potential multiplicity of combinations between the five or six major classes of antihypertensive drug.

  4. Consistent antioxidant and antihypertensive effects of oral sodium nitrite in DOCA-salt hypertension

    Full Text Available Hypertension is a common disease that includes oxidative stress as a major feature, and oxidative stress impairs physiological nitric oxide (NO activity promoting cardiovascular pathophysiological mechanisms. While inorganic nitrite and nitrate are now recognized as relevant sources of NO after their bioactivation by enzymatic and non-enzymatic pathways, thus lowering blood pressure, mounting evidence suggests that sodium nitrite also exerts antioxidant effects. Here we show for the first time that sodium nitrite exerts consistent systemic and vascular antioxidant and antihypertensive effects in the deoxycorticosterone-salt (DOCA-salt hypertension model. This is particularly important because increased oxidative stress plays a major role in the DOCA-salt hypertension model, which is less dependent on activation of the renin-angiotensin system than other hypertension models. Indeed, antihypertensive effects of oral nitrite were associated with increased plasma nitrite and nitrate concentrations, and completely blunted hypertension-induced increases in plasma 8-isoprostane and lipid peroxide levels, in vascular reactive oxygen species, in vascular NADPH oxidase activity, and in vascular xanthine oxidoreductase activity. Together, these findings provide evidence that the oral administration of sodium nitrite consistently decreases the blood pressure in association with major antioxidant effects in experimental 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.

    Arterial hypertension is a major risk factor for cardiovascular and renal events. Lowering blood pressure is thus an important strategy for reducing morbidity and mortality. Since low-dose aspirin is a cornerstone in the prevention of adverse cardiovascular outcomes, combined treatment with aspirin and antihypertensive drugs is very common. However, the impact of aspirin therapy on blood pressure control remains a subject of intense debate. Recent data suggest that the cardioprotective action of aspirin extends beyond its well-known antithrombotic effect. Aspirin has been shown to trigger the synthesis of specialized pro-resolving lipid mediators from arachidonic acid and omega-3 fatty acids. These novel anti-inflammatory and pro-resolving mediators actively stimulate the resolution of inflammation and tissue regeneration. Additionally, they may contribute to other protective effects on redox status and vascular reactivity that have also been attributed to aspirin. Of note, aspirin has been shown to improve vasodilation through cyclooxygenase-independent mechanisms. On the other hand, higher aspirin doses have been reported to exert a negative impact on blood pressure due to inhibition of cyclooxygenase-2 activity, which reduces renal blood flow, glomerular filtration rate and sodium and water excretion. This review aims to provide an overview of the effects of aspirin on blood pressure and the underlying mechanisms, focusing on the interaction between aspirin and antihypertensive drugs. Studies in both experimental and human hypertension are presented. Copyright © 2017 Sociedade Portuguesa de Cardiologia. Publicado por Elsevier España, S.L.U. All rights reserved.

    24 hypertensive patients were randomised into 2 groups to compare the antihypertensive effects of enalapril and captopril over a 10-week period. In the hydrochlorothiazide run-in period, blood pressure was reduced from 171 +/- 4/109 +/- 1mm Hg to 160 +/- 4/103 +/- 1mm Hg (p less than 0.05). Angiotensin-converting enzyme (ACE) inhibition decreased blood pressure to 132 +/- 3/87 +/- 2mm Hg. Captopril decreased diastolic blood pressure significantly more after 3 hours than enalapril (-24 versus -17mm Hg, p less than 0.05). After 10 weeks of therapy, this antihypertensive response was maintained at 134 +/- 3/83 +/- 1mm Hg. There was no difference between the captopril and enalapril treated groups. Acute and chronic responses of plasma renin activity, plasma aldosterone and ACE were determined. There was an acute positive correlation between the rise in plasma renin activity and the fall in blood pressures with captopril but not with enalapril. With chronic treatment there was no difference in the ability of either of the 2 drugs to reduce blood pressure, inhibit ACE, reduce aldosterone or stimulate plasma renin activity.

    The goal of this study was to establish an integrated indirect response pharmacokinetic-pharmacodynamic model between telmisartan and hydrochlorothiazide to describe the antihypertensive interaction of these two drugs in spontaneously hypertensive rats. The blood pressure and plasma concentrations were measured by the tail-cuff test and high performance liquid chromatography-mass spectrometry, respectively, in spontaneously hypertensive rats. The current pharmacokinetic-pharmacodynamic model was based on the non-competitive pharmacodynamic interaction of two drugs acting on different physiological processes. This model was able to acquire the temporal changes in drug concentration and blood pressure after administration of telmisartan or hydrochlorothiazide. The noncompetitive pharmacodynamic interaction assumed that the decreased blood pressure was attributed to the inhibitory function of telmisartan and stimulatory function of hydrochlorothiazide after administration of these two drugs. There was no significant pharmacokinetic change of telmisartan and hydrochlorothiazide in the different groups tested. The model predicted a synergistic pharmacodynamic interaction when telmisartan was administered in combination with hydrochlorothiazide, which was notably stronger than if the effects were additive. The results showed that the presented pharmacokinetic-pharmacodynamic model was suitable for describing the antihypertensive interaction between telmisartan and hydrochlorothiazide. © 2014 Royal Pharmaceutical Society.

    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 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. PMID:29201276

    Regular recertification is mandatory to maintain board certification status in all specialties. However, the evidence that physicians' performance decreases with time since initial certification is limited. We therefore carried out a study to determine whether the frequency of antihypertensive treatment intensification for diabetic patients changes with time since their physicians' last board certification. In this retrospective cohort study, we analyzed treatment of 8127 hypertensive patients with diabetes mellitus treated by 301 internists at primary care practices affiliated with 2 large academic hospitals. Patient visits with documented blood pressure > or = 130/85 mm Hg between January 1, 2000, and August 31, 2005, were studied. The association between the number of years since the physician's last board certification and the probability of pharmacological antihypertensive treatment intensification at a given visit was analyzed. Frequency of treatment intensification decreased from 26.7% for physicians who were board certified the previous year to 6.9% for physicians who were board certified 31 years before the visit. Treatment intensification rate was 22.5% for physicians certified 10 years ago (Pboard certification, the probability of treatment intensification decreased by 21.3% (P=0.0097). Physician intensification of pharmacological therapy for blood pressure levels above the recommended treatment goals decreases with time since the last board certification. This finding supports the current policy of mandatory recertification.

    Water extract of Marrubium vulgare is widely used as antihypertensive treatment in folk medicine. We have compared the effect of 10-week-long treatment with amlodipine or Marrubium water extract on systolic blood pressure (SBP), cardiovascular remodeling and vascular relaxation in spontaneously hypertensive rats (SHR). Both treatments produced similar decrease in SBP. Amlodipine treatment reduced left ventricle, aortic and mesenteric artery weight. Marrubium treatment had a significant antihypertrophic effect in aorta only. Relaxation to acetylcholine (ACh) of mesenteric artery was improved by Marrubium but not by amlodipine treatment. These results demonstrate that, in addition to its antihypertensive effect, Marrubium water extract improved the impaired endothelial function in SHR.

    Background In spite of many benefits for individuals and community, self-medication has a number of potential risks. Objective To identify predictors of self-medication with over-the-counter and prescription (Rx) medicines without doctor's prescription. Setting Serbian population of 15 years of age and over. Method This was crosssectional, epidemiological study. Data have been drawn from Serbian National Health Survey 2013 database. Predictors of self-medication were determined among sociodemographic, health related and health services related factors, using multivariate logistic regression models. Main outcome measure Prevalence and predictors of selfmedication. Results The study included 14,623 participants. The prevalence of selfmedication was 27.1 and 24% after exclusion of vitamins, minerals and herbal preparations. Medicines for pain relief were the mostly used medicines without doctors' prescription in 18.4% of participants. A relatively high prevalence of self-medication with Rx medicines, (1) tranquilizers and sleeping pills, (2) antibiotics and (3) antihypertensives, was found, 4, 2.5 and 1.9%, respectively. Socio-demographic factors (middle age, female gender, higher level of education), health related factors (chronic disease, stress, physical pain), and health service related factors (nonrealized healthcare needs due to long waiting, dissatisfaction with publicly funded health services) have been found as significantly associated with self-medication. Conclusion Self-medication in Serbia is predicted by socio-demographic and health related factors, unmet needs for healthcare and dissatisfaction with publicly funded healthcare services. Improvements in healthcare system, particularly, shortening of long waiting for healthcare services and improvements in pharmaceutical services, particularly better control of Rx medicines dispensing, could contribute in improvement of responsible self-medication.

    The German hospital sector is characterized by a profound deficit in organizational integration. The implementation of centers as one way to improve the situation is complicated by the heterogeneity of the concept and understanding of the term "center". The author proposes to distinguish between functional, divisional and process-oriented centers. In German hospitals where the transition from functional to divisional organization is under way matrix elements can be expected to be introduced into organizational practice. Process-oriented centers like breast centers represent matrix components by simultaneously applying functional and process-oriented perspectives. Matrix components map the complexity of clinical structures, but increase coordination and management load and should be applied only to a limited number of care processes.

    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.
