As with adults, pediatric patients with HTN can present with hypertensive crises include hypertensive urgency and hypertensive emergencies. However, pediatric blood pressure problems have a greater chance of being from secondary causes of HTN, as opposed to primary HTN, than in adults. Thorough evaluation of a child with a hypertensive emergency includes accurate blood pressure readings, complete and focused symptom history, and appropriate past medical, surgical, and family history. Physical exam should include height, weight, four-limb blood pressures, a general overall examination and especially detailed cardiovascular and neurological examinations, including fundoscopic examination. Initial work-up should typically include electrocardiography, chest X-ray, serum chemistries, complete blood count, and urinalysis. Initial management of hypertensive emergencies generally includes the use of intravenous or oral antihypertensive medications, as well as appropriate, typically outpatient, follow-up. Emergency department goals for hypertensive crises are to (1 safely lower blood pressure, and (2 treat/minimize acute end organ damage, while (3 identifying underlying etiology. Intravenous antihypertensive medications are the treatment modality of choice for hypertensive emergencies with the goal of reducing systolic blood pressure by 25% of the original value over an 8

    Urinary urgency is an adverse sensory experience. Confirmation of the multidimensional nature of other adverse sensory experiences such as pain and dyspnea has improved the understanding of neurophysiological and perceptual mechanisms leading to innovations in assessment and treatment. It has been suggested that the sensation of urgency may include multiple dimensions such as intensity, suddenness and unpleasantness. In this systematic review we determine which dimensions of sensation have been assessed by instruments used to measure urinary urgency. A systematic search was undertaken of MEDLINE, Embase, AMED, CINAHL, Ageline, Web of Science, InformIT Health and Scopus databases to identify studies that included assessments of urinary urge or urgency. Articles were included in the analysis if they were primary studies that described the method used to measure urge/urgency in adults and published in English in peer reviewed publications since January 1, 2000. Articles were excluded from study if urgency was measured only in conjunction with other symptoms (eg frequency or incontinence) or if there was no English version of the instrument. Secondary analyses and systematic reviews were retained to hand search references for additional primary studies. Data were extracted for the instruments used to measure urge/urgency. For each instrument the items specific to urinary urgency were reviewed using a prospectively developed categorization process for the sensory dimension and the measurement metric. Items used to assess urinary urgency were collated in a matrix (sensory dimensions vs assessment metric). The most frequently used dimensions, metrics and combinations were descriptively analyzed. After removal of duplicate articles 1,048 full text articles were screened and 411 were excluded, leaving 637 eligible articles from which data were extracted. A total of 216 instruments were identified which were 1 of 6 types, namely 1) wider symptom questionnaires, 2) urgency

    Hypertensive urgency/emergency is a common and potentially life threatening condition that is characterised by a rapid and strong increase in blood pressure. It is estimated that hypertensive urgencies/emergencies account for 25 % of all patient visits in the medical section of emergency departments. Between 24 September 2007 and 06 September 2008, we investigated 195 persons with hypertensive events who were admitted to the emergency unit of the University Clinic St. Josef Hospital in Bochum. After stabilization of blood pressure, the patients were sent to the ward for further evaluation. Aldosterone, renin, and cortisol levels were monitored during the first 24 hours. Blood was taken at 8 am after 2 hours in supine position and after mobilization at 10 am. Meteorological data at the time of admission were analyzed for potential associations with the temporary accumulation of hypertensive events. The meteorological parameters were air temperature TA, relative humidity RH, air pressure P, and sunshine duration SD, observed at the meteorological station in Duesseldorf (airport). In addition, perceived temperature PT was calculated and included in the analysis. First results indicate that the hypertensive events occurred on days when TA departed on average -0.28 K (95 % confidence interval: -0.59 to -0.03 K) and PT deviated on average -0.43 K (-0.82 to -0.04) from the respective values of the preceding day. On days without hypertensive events TA was on average 0.21 (-0.08 to 0.49) and PT was on average 0.32 K (-0.04 to 0.68) higher than on the day before. Days with and days without cases of hypertensive events were, with respect to the daily TA and PT changes, significantly different (TA: p = 0.012; PT: p = 0.003). On days with lower PT than on the previous day the probability of a hospital admission due to a hypertensive event was more than twice as high as on days with higher PT than on the day before. These first results indicate a potential relationship between

    Prehospital hypertensive emergencies and urgencies are common, but evidence is lacking. Telemedically supported hypertensive emergencies and urgencies were prospectively collected (April 2014-March 2015) and compared retrospectively with a historical control group of on-scene physician care in the emergency medical service of Aachen, Germany. Blood pressure management and guideline adherence were evaluated. Telemedical (n=159) vs conventional (n=172) cases: blood pressure reductions of 35±24 mm Hg vs 44±23 mm Hg revealed a group effect adjusted for baseline differences (P=.0006). Blood pressure management in categories: no reduction 6 vs 0 (P=.0121); reduction ≤25% (recommended range) 113 vs 110 patients (P=.2356); reduction >25% to 30% 13 vs 29 (0.020); reduction >30% 12 vs 16 patients (P=.5608). The telemedical approach led to less pronounced blood pressure reductions and a tendency to improved guideline adherence. Telemedically guided antihypertensive care may be an alternative to conventional care especially for potentially underserved areas. ©2017 Wiley Periodicals, Inc.

    The objective of this study is to evaluate the effectiveness of existing physiotherapy modalities for the treatment of urge urinary incontinence (UUI). A systematic review was performed for primary studies of physiotherapy techniques for UUI published in English between 1996 and August 2010 in major electronic databases. Only randomized clinical trials that reported outcomes separately for women with UUI were included. Outcomes assessed were reduction in UUI, urinary frequency, and nocturia. Data from 13 full-text trials including the modalities of pelvic floor muscles exercises with or without biofeedback, vaginal electrical stimulation, magnetic stimulation, and vaginal cones were analyzed. The methodologic quality of these trials was fair. Significant improvement in UUI was reported for all physiotherapy techniques except vaginal cone therapy. There are insufficient data to determine if pelvic physiotherapy improves urinary frequency or nocturia. Evidence suggests that physiotherapy techniques may be beneficial for the treatment of UUI.

    Full Text Available This narrative systematic review evaluates growing evidence of an association between low maternal vitamin D status and increased risk of hypertensive disorders. The inclusion of interventional, observational, and dietary studies on vitamin D and all hypertensive disorders of pregnancy is a novel aspect of this review, providing a unique contribution to an intensively-researched area that still lacks a definitive conclusion. To date, trial evidence supports a protective effect of combined vitamin D and calcium supplementation against preeclampsia. Conflicting data for an association of vitamin D with gestational hypertensive disorders in observational studies arises from a number of sources, including large heterogeneity between study designs, lack of adherence to standardized perinatal outcome definitions, variable quality of analytical data for 25-hydroxyvitamin D (25(OHD, and inconsistent data reporting of vitamin D status. While evidence does appear to lean towards an increased risk of gestational hypertensive disorders at 25(OHD concentrations <50 nmol/L, caution should be exercised with dosing in trials, given the lack of data on long-term safety. The possibility that a fairly narrow target range for circulating 25(OHD for achievement of clinically-relevant improvements requires further exploration. As hypertension alone, and not preeclampsia specifically, limits intrauterine growth, evaluation of the relationship between vitamin D status and all terms of hypertension in pregnancy is a clinically relevant area for research and should be prioritised in future randomised trials.

    Full Text Available Resumen Las crisis hipertensivas son un conjunto de situaciones clínicas de variada gravedad y pronóstico. Las diferencias entre urgencias y emergencias hipertensivas radican en la existencia o no de riesgo vital por afectación de órganos diana, más que por los niveles de presión arterial. Las urgencias hipertensivas no suelen comportar riesgo vital inmediato por lo que el tratamiento puede iniciarse, incluso completarse, en el medio extrahospitalario. Las emergencias hipertensivas son situaciones clínicas muy graves que requieren asistencia hospitalaria. Ante un paciente con hipertensión grave, asintomático o con síntomas inespecíficos debe adoptarse una actitud terapéutica prudente. La primera medida será comprobar las cifras de presión arterial con tomas repetidas de la misma y tratar los posibles factores desencadenantes. El objetivo del tratamiento de las urgencias hipertensivas es tanto obtener una reducción de las cifras de presión arterial (al menos un 20% de las cifras basales como evitar reducciones bruscas y/o excesivas de la misma. En las urgencias hipertensivas no deberían utilizarse fármacos de acción rápida por el riesgo de accidentes isquémicos y utilizar fármacos con vida media más larga. El riesgo cardiovascular de estos pacientes es superior al de los hipertensos que no sufren una crisis hipertensiva. En las emergencias hipertensivas la elección del fármaco deberá individualizarse. La vía parenteral es la forma habitual de la administración de fármacos.

    Hypertension is reported to be the most prevalent risk factor for cardiovascular disease in elite athletes. We aimed to review blood pressure (BP) and prevalence of hypertension in different elite athletes, and study whether there was an association between high BP and left ventricular hypertrophy (LVH). A systematic review of studies reporting BP in athletes using search strategies developed for PubMed and EMBASE, including only studies with ≥100 participants. We collected data on BP, prevalence of hypertension, LVH and methods of BP measurement. Of 3723 records identified, 51 met the inclusion criteria. These included men and women (n=138,390), aged mostly between 18 and 40 years, from varied sports disciplines. Mean systolic BP varied from 109±11 to 138±7 mm Hg and mean diastolic BP from 57±12 to 92±10 mm Hg. Strength-trained athletes had higher BP than endurance-trained athletes (131.3±5.3/77.3±1.4 vs 118.6±2.8/71.8±1.2 mm Hg, phypertension varied from 0% to 83%. Some studies showed an association between high BP and LVH. Measurement methods were poorly standardised. BP and prevalence of hypertension in athletes varied considerably partly because of variations in methodology, but type and intensity of training may contribute towards higher BP. High BP may be associated with LVH. Published by the BMJ Publishing Group Limited.

    The objective of this review is to systematically review the evidence for the effectiveness of aromatherapy in the treatment of high blood pressure. Twelve databases were searched from their inception through December 2009. Controlled trials testing aromatherapy in patients with hypertension of any origin that assessed blood pressure were considered. The selection of studies, data extraction and validations were performed independently by two reviewers. One randomized clinical trial (RCT) and four non-randomized controlled clinical trials (CCTs) met our inclusion criteria. The one RCT included tested the effects of aromatherapy as compared with placebo and showed significant reduction of systolic blood pressure and diastolic blood pressure. All of the four CCTs showed favourable effects of aromatherapy. However, all of the CCTs also had a high risk of bias. The existing trial evidence does not show convincingly that aromatherapy is effective for hypertension. Future studies should be of high quality with a particular emphasis on designing an adequate control intervention. © 2010 Blackwell Publishing Ltd.

    Pulmonary arterial hypertension (PAH), as a life-threatening disease with no efficient cure, may impose a tremendous economic burden on patients and healthcare systems. However, most existing studies have mainly emphasised epidemiology and medications, while large observational studies reporting on the economic burden are currently lacking. To review and evaluate evidence on the costs of PAH and the cost effectiveness of PAH treatments, and to summarise the corresponding cost drivers. Systematic literature searches were conducted in English-language databases (PubMed, Web of Science, ScienceDirect) and Chinese-language databases (China National Knowledge Infrastructure, Wanfang Data, Chongqing VIP) to identify studies (published from 2000 to 2014) assessing the costs of PAH or the cost effectiveness of PAH treatments. The search results were independently reviewed and extracted by two reviewers. Costs were converted into 2014 US dollars. Of 1959 citations identified in the initial search, 19 papers were finally included in this analysis: eight on the economic burden of PAH and 11 on economic evaluation of PAH treatments. The economic burden on patients with PAH was rather large, with direct healthcare costs per patient per month varying from $2476 to $11,875, but none of the studies reported indirect costs. Sildenafil was universally reported to be a cost-effective treatment, with lower costs and better efficacy than other medications. Medical costs were reported to be the key cost drivers. The economic burden of patients with PAH is substantial, while the paucity of comprehensive country-specific evidence in this area and the lack of reports on indirect costs of PAH warrant researchers' concern, especially in China.

    Full Text Available Abstract Background Hypertension is a major risk factor for many cardiovascular diseases in developing countries. A comprehensive review of the prevalence of hypertension provides crucial information for the evaluation and implementation of appropriate programmes. Methods The PubMed and Google Scholar databases were searched for published articles on the population-based prevalence of adult hypertension in Ghana between 1970 and August 2009, supplemented by a manual search of retrieved references. Fifteen unique population-based articles in non-pregnant humans were obtained. In addition, two relevant unpublished graduate student theses from one university department were identified after a search of its 1996-2008 theses. Results The age and sex composition of study populations, sampling strategy, measurement of blood pressure, definition of hypertension varied between studies. The prevalence of hypertension (BP ≥ 140/90 mmHg ± antihypertensive treatment ranged from 19% to 48% between studies. Sex differences were generally minimal whereas urban populations tended to have higher prevalence than rural population in studies with mixed population types. Factors independently associated with hypertension included older age group, over-nutrition and alcohol consumption. Whereas there was a trend towards improved awareness, treatment and control between 1972 and 2005, less than one-third of hypertensive subjects were aware they had hypertension and less than one-tenth had their blood pressures controlled in most studies. Conclusion Hypertension is clearly an important public health problem in Ghana, even in the poorest rural communities. Emerging opportunities such as the national health insurance scheme, a new health policy emphasising health promotion and healthier lifestyles and effective treatment should help prevent and control hypertension.

    Laparoscopic splenectomy has become the gold-standard procedure for normal to moderately enlarged spleens. However, the safety of laparoscopic splenectomy for patients with portal hypertension remains controversial. We carried out this systematic review to identify the feasibility and safety of laparoscopic splenectomy in treating portal hypertension. A systematic search for comparative studies that compared laparoscopic splenectomy with open splenectomy for portal hypertension was carried out. Studies were independently reviewed for quality, inclusion and exclusion criteria, demographic characteristics, and perioperative outcomes. Although laparoscopic splenectomy is associated with longer operating time, it offers advantages over the open procedure in terms of less blood loss, lower operative complications, earlier resumption of oral intake, and shorter posthospital stay. Therefore, laparoscopic splenectomy is a safe and feasible intervention for portal hypertension. © The Author(s) 2014.

    Objective Whether there is an association or a cause-and-effect relationship between epistaxis and hypertension is a subject of longstanding controversy. The objective of this systematic review and meta-analysis was to determine the association between epistaxis and hypertension and to verify whether hypertension is an independent risk factor of epistaxis. Data Sources A comprehensive search was performed using the MEDLINE, EMBASE, and Cochrane Library databases. Review Methods The review was performed according to the Meta-analysis of Observational Studies in Epidemiology guidelines and reported using the Preferred Reporting Items for Systematic Reviews and Meta-analysis guidelines. Results We screened 2768 unique studies and selected 10 for this meta-analysis. Overall, the risk of epistaxis was significantly increased for patients with hypertension (odds ratio, 1.532 [95% confidence interval (CI), 1.181-1.986]; number needed to treat, 14.9 [95% CI, 12.3-19.0]). Results of the Q test and I 2 statistics suggested considerable heterogeneity ([Formula: see text] = 0.038, I 2 = 49.3%). The sensitivity analysis was performed by excluding 1 study at a time, and it revealed no change in statistical significance. Conclusion Although this meta-analysis had some limitations, our study demonstrated that hypertension was significantly associated with the risk of epistaxis. However, since this association does not support a causal relationship between hypertension and epistaxis, further clinical trials with large patient populations will be required to determine the impact of hypertension on epistaxis.

    Full Text Available Established standards for first-line hypertension management include lifestyle modification and behavior change. The degree to which and how lifestyle modification is systematically integrated into studies of first-line drug management for hypertension is of methodological and clinical relevance. This study systematically reviewed the methodology of articles from a recent Cochrane review that had been designed to inform first-line medical treatment of hypertension and was representative of high quality established clinical trials in the field. Source articles (n=34 were systematically reviewed for lifestyle interventions including smoking cessation, diet, weight loss, physical activity and exercise, stress reduction, and moderate alcohol consumption. 54% of articles did not mention lifestyle modification; 46% contained nonspecific descriptions of interventions. We contend that hypertension management research trials (including drug studies need to elucidate the benefits and risks of drug-lifestyle interaction, to support the priority of lifestyle modification, and that lifestyle modification, rather than drugs, is seen by patients and the public as a priority for health professionals. The inclusion of lifestyle modification strategies in research designs for hypertension drug trials could enhance current research, from trial efficacy to clinical outcome effectiveness, and align hypertension best practices of a range of health professionals with evidence-based knowledge translation.

    Create a sense of urgency and “fear of missing out” (FOMO) to nudge people to book faster. People feel more compelled to buy if they believe they are about to miss out on a limited-time offer or a good deal. This type of urgency is about creating “scarcity value,” a concept that OTAs have mastered and implemented systematically on their OTA websites to stimulate purchase behavior.

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

    The risk of hypertension in adults who regularly take a nap is controversial. The objective of this meta-analysis was to assess the associations between napping and hypertension. A literature search was performed using MEDLINE, EMbase and The Cochrane Database of Systematic Reviews from inception through October, 2015. Studies that reported relative risks, odd ratios or hazard ratios comparing the risk of hypertension in individuals who regularly take nap were included. Pooled risk ratios (RR) and 95% confidence interval (CI) were calculated using a random-effect, generic inverse variance method. Nine observational studies with 112,267 individuals were included in the analysis to assess the risk of hypertension in nappers. The pooled RR of hypertension in nappers was 1.13 with 95% CI (0.98 to 1.30). When meta-analysis was limited only to studies assessing the risk of hypertension in daytime nappers, the pooled RR of hypertension was 1.19 with 95% CI (1.06 to 1.35). The data on association between nighttime napping in individuals who work night shift and hypertension were limited, only one observational study reported reduced risk of hypertension in nighttime nappers with odds ratio of 0.79 with 95% CI (0.63 to 1.00). Our meta-analysis demonstrates a significant association between daytime napping and hypertension. Future study is needed to assess the potential benefits of HTN screening for daytime nappers. © 2016 Chinese Cochrane Center, West China Hospital of Sichuan University and John Wiley & Sons Australia, Ltd.

    Full Text Available Ramadan is a holy month for Muslims and fasting in this month is the rule for any healthy matured person. Nutritional and behavioral changes occurred during Ramadan fasting may lead to several physiological change, such as blood pressure (2. Studies evaluated the effects of Ramadan fasting on blood pressure in hypertensive patients, are scarce and reported inadequate results. In this paper a systematic review was performed to accumulate the results of published literature designed to evaluate blood pressure changes in hypertensive patients due to Ramadan fasting. All prospective, English studies which evaluated the effects of Ramadan fasting on blood pressure in hypertensive patients and measured systolic and diastolic blood pressure twice at least ( before Ramadan and during last week of Ramadan or after Ramadan fasting were included in systematic review . Five studies reported the effect of Ramadan fasting on blood pressure in hypertensive patients in full text. Although significant reduction in systolic blood pressure during Ramadan fasting were seen in 3 studies (3-5, other 3 studies reported no significant difference between systolic blood pressure before and after Ramadan fasting (6, 7. Among 6 studies that reviewed in this paper, 4 studies reported no significant changes in diastolic blood pressure (4, 6, 7. While 2 other studies reported significant reduction in systolic blood pressure after Ramadan fasting (3, 5. This systematic review suggested that Ramadan fasting can be safe in treated essential hypertensive patients with continuation of previous medications. Also it can improve systolic and diastolic blood pressures.

    The etiology of hypertension is various and complex, involving both genetic and behavioral factors. The relationship between psychosocial stress and hypertension has been hypothesized. More and more people experience increased anxiety, depression, and chronic psychosocial stress brought on by globalization, cultural changes, socioeconomic changes, and stress at the work place. Although a plethora of studies have investigated the interaction between psychosocial stress and hypertension, this relationship is still contentious. The objective of this study is twofold. First, a review of recent advancements in our understanding of the relationship between psychosocial stress and hypertension. Second, a meta-analysis aiming to assess the relationship between chronic psychosocial stress and blood pressure. We systematically searched and identified relevant studies from five databases, including PubMed, Cochrane Library, China National Knowledge Infrastructure (CNKI), CQVIP, and the Wanfang Database until April 2016. Eleven studies encompassing 5696 participants were included in the final analysis. Data showed that psychosocial stress was associated with an increased risk of hypertension (OR = 2.40, 95% CI = 1.65-3.49), and hypertensive patients had a higher incidence of psychosocial stress compared to normotension patients (OR = 2.69, 95% CI = 2.32-3.11). Based on our meta-analysis, chronic psychosocial stress may be a risk factor for hypertension. The few cohort and case-control studies on the association between psychosocial stress and hypertension employed variable definition of stressors and the responses, making the meta-analysis difficult. Although we found an association between chronic psychosocial stress and hypertension, more studies are needed to confirm this relationship.

    Chinese herbal medicine has been used to treat hypertension in China and East Asia since centuries. In this study, we conduct an overview of systematic reviews of Chinese herbal medicine in the treatment of primary hypertension to 1) summarize the conclusions of these reviews, 2) evaluate the methodological quality of these reviews, and 3) rate the confidence in the effect on each outcome. We comprehensively searched six databases to retrieve systematic reviews of Chinese herbal medicine for primary hypertension from inception to December 31, 2015. We used AMSTAR to evaluate the methodological quality of included reviews, and we classified the quality of evidence for each outcome in included reviews using the GRADE approach. A total of 12 systematic reviews with 31 outcomes were included, among which 11 systematic reviews focus on the therapeutic effect of Chinese herbal medicine combined with conventional medicine or simple Chinese herbal medicine versus simple conventional medicine. Among the 11 items of AMSTAR, the lowest quality was "providing a priori design" item, none review conformed to this item, the next was "stating the conflict of interest" item, only three reviews conformed to this item. Five reviews scored less than seven in AMSTAR, which means that the overall methodological quality was fairly poor. For GRADE, of the 31 outcomes, the quality of evidence was high in none (0 %), moderate in three (10 %), low in 19 (61 %), and very low in nine (29 %). Of the five downgrading factors, risk of bias (100 %) was the most common downgrading factor in the included reviews, followed by imprecision (42 %), inconsistency (39 %), publication bias (39 %), and indirectness (0 %). The methodological quality of systematic reviews about Chinese herbal medicine for primary hypertension is fairly poor, and the quality of evidence level is low. Physicians should be cautious when applying the interventions in these reviews for primary hypertension patients in

    Full Text Available Objective. To evaluate the effectiveness of astragalus injection (a traditional Chinese patent medicine for patients with renal damage induced by hypertension according to the available evidence. Methods. We searched MEDLINE, China National Knowledge Infrastructure (CNKI, Chinese VIP Information, China Biology Medicine (CBM, and Chinese Medical Citation Index (CMCI, and the date of search starts from the first of database to August 2011. No language restriction was applied. We included randomized controlled trials testing astragalus injection against placebo or astragalus injection plus antihypertensive drugs against antihypertensive drugs. Study selection, data extraction, quality assessment, and data analyses were conducted according to the Cochrane review standards. Results. 5 randomized trials (involving 429 patients were included and the methodological quality was evaluated as generally low. The pooled results showed that astragalus injection was more effective in lowering β2-microglobulin (β2-MG, microalbuminuria (mAlb compared with placebo, and it was also superior to prostaglandin in lowering blood urea nitrogen (BUN, creatinine clearance rate (Ccr. There were no adverse effects reported in the trials from astragalus injection. Conclusions. Astragalus injection showed protective effects in hypertensive renal damage patients, although available studies are not adequate to draw a definite conclusion due to low quality of included trials. More rigorous clinical trials with high quality are warranted to give high level of evidence.

    Massage, an ancient Chinese healing art, is widely practiced for symptom relief in hypertensive patients with anxiety, depression, headache, vertigo, chronic pain in neck, shoulder and back. A large number of case series and clinical trials have been published. However, it is still unclear whether massage can be recommended as an effective therapy for essential hypertension (EH). We estimated the current clinical evidence of massage for EH. Articles published before 10 December 2013 were searched using Cochrane Library, PubMed, EMBASE, Chinese Scientific Journal Database (VIP), Chinese Biomedical Literature Database, Wanfang data and Chinese National Knowledge Infrastructure. Randomized controlled trials comparing massage with any type of control intervention were included. Trials testing massage combined with antihypertensive drugs versus antihypertensive drugs were included as well. Meta-analysis was performed on the effects on blood pressure (BP). Twenty-four articles involving 1962 patients with EH were selected. Methodological quality of most trials was evaluated as generally low. Meta-analyses demonstrated that massage combined with antihypertensive drugs may be more effective than antihypertensive drugs alone in lowering both systolic BP (SBP; mean difference (MD): -6.92 (-10.05, -3.80); Phypertensive patients as compared with antihypertensive drugs. Safety of massage is still unclear. There is some encouraging evidence of massage for EH. However, because of poor methodological quality, the evidence remains weak. Rigorously designed trials are needed to validate the use of massage in future.

    Hypertensive disorders of pregnancy (HDPs), that is chronic hypertension, gestational hypertension, pre-eclampsia (de novo or superimposed on chronic hypertension) and white coat hypertension, affect approximately 5%-15% of pregnancies. HDP exposure has been linked to an increased risk of autism spectrum disorder, attention deficit\\/hyperactivity disorder and other neurodevelopmental disorders in children. However, findings are inconsistent, and a clear consensus on the impact of HDPs on the risk of neurodevelopmental disorders is needed. Therefore, we aim to synthesise the published literature on the relationship between HDPs and the risk of neurodevelopmental disorders in the form of a systematic review and meta-analysis.

    In the past decade, garlic has become one of the most popular complementary therapies for blood pressure (BP) control used by hypertensive patients. Numerous clinical studies have focused on the BP-lowering effect of garlic, but results have been inconsistent. Overall, there is a dearth of information available to guide the clinical community on the efficacy of garlic in hypertensive patients. To systematically review the medical literature to investigate the current evidence of garlic for the treatment of hypertension. PubMed, the Cochrane Library and EMBASE were searched for appropriate articles from their respective inceptions until August 2014. Randomized, placebo-controlled trials comparing garlic vs. a placebo in patients with hypertension were considered. Papers were independently reviewed by two reviewers and were analyzed using Cochrane software Revman 5.2. A total of seven randomized, placebo-controlled trials were identified. Compared with the placebo, this meta-analysis revealed a significant lowering effect of garlic on both systolic BP (WMD: -6.71 mmHg; 95% CI: -12.44 to -0.99; P = 0.02) and diastolic BP (WMD: -4.79 mmHg; 95% CI: -6.60 to -2.99; P garlic is an effective and safe approach for hypertension. However, more rigorously designed randomized controlled trials focusing on primary endpoints with long-term follow-up are still warranted before garlic can be recommended to treat hypertensive patients.

    The role of gestational hypertensive disorders, which includes both pre-eclampsia and gestational hypertension, in the development of retinopathy of prematurity (ROP) has been controversial. Therefore, this systematic review and meta-analysis is to evaluate the association between gestational hypertensive disoders and ROP. Eligible studies published up to June 5, 2016 were identified from MEDLINE and EMBASE that evaluated the association between the two conditions. Totally 1142 published records were retrieved for screening, 925 of them eligible for detailed evaluation. Finally 19 studies involving 45281 infants with 5388 cases of ROP met our criteria for meta-analysis. Gestational hypertensive disorders were not associated with ROP (unadjusted OR: 0.89; P = 0.38; adjusted OR: 1.35; P = 0.18). Subgroup analyses also revealed no significant association between ROP with pre-eclampsia (unadjusted OR: 0.85; P = 0.29; adjusted OR:1.29; P = 0.28) or with gestational hypertension (unadjusted OR: 1.10; P = 0.39; adjusted OR: 1.25; P = 0.60) separately. Sensitivity analysis indicated our results were robust. We concluded no significant association between gestational hypertensive disorders and ROP. More large scale well-conducted prospective cohorts on the topic are needed.

    Health administrative data are frequently used for hypertension surveillance. The aim of this systematic review was to determine the sensitivity and specificity of the commonly used hypertension case definition of 2 physician outpatient claims within a 2-year period or 1 hospital discharge abstract record. Following Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, we searched MEDLINE (from 1946) and EMBASE (from 1947) for relevant studies through September 2016 (keywords: "hypertension," "administrative databases," "validation studies"). Data with standardized forms and assessed quality using Quality Assessment of Diagnostic Accuracy Studies criteria were reviewed by 2 reviewers. Pooled sensitivity and specificity were estimated using a generalized linear-model approach to random-effects bivariate regression meta-analysis. The search strategy identified 1732 abstracts, among which 3 articles were deemed relevant. One of the articles incorporated 2 studies with differing reference standards and study populations; thus, we considered each separately. The quality scores of the retained studies ranged from 10-12 of a maximum 14. The sensitivity of the definition investigated to identify hypertension using administrative health databases was 71.2% (95% confidence interval [CI], 68.3-73.7) and the specificity was 94.5% (95% CI, 93.2-95.6) when compared with surveys or medical records. The 2 physician outpatient claims within a 2-year period or 1 hospital discharge abstract record hypertension case definition accurately classifies individuals as hypertensive in approximately 70% of cases and correctly identifies persons as nonhypertensive in approximately 95% of cases. This is likely sufficiently sensitive and specific for most research and surveillance purposes. Copyright © 2017 Canadian Cardiovascular Society. Published by Elsevier Inc. All rights reserved.

    Full Text Available Hypertension is a common disease associated with important cardiovascular complications. Persistent blood pressure of 140/90 or higher despite combined use of a reninangiotensin system blocker, calcium channel blocker and a diuretic at highest tolerated doses constitutes resistant hypertension. Excess sympathetic activity plays an important pathogenic role in resistant hypertension in addition to contributing to the development of metabolic problems, in particular diabetes. Reduction of renal sympathetic activity by percutaneous catheter-based radiofrequency ablation via the renal arteries has been shown in several studies to decrease blood pressure in patients with resistant hypertension, and importantly is largely free of significant complications. However, longer term follow-up is required to confirm both long-term safety and efficacy.

    Many of the risk factors for heart disease have recently been shown to develop during childhood such as left ventricular hypertrophy and fibrous plaque lesions. As risk for cardiovascular disease in children and adolescents has risen, sleep duration has decreased, and inadequate sleep in children and adolescents has been found to be associated with cardiovascular disease risk. The aims of this manuscript are to provide an updated systematic review of the literature assessing sleep, hypertension, and cardiovascular risk and evaluate the strength of the evidence based on the available research. A systematic review was conducted using six databases from January 1, 2015 through March 9, 2018. We sought studies which looked at the relationship between sleep duration, sleep timing, or sleep quality and outcome variables of hypertension, inflammation, obesity, glucose or insulin, and lipids in children and adolescents. We found 24 studies which met our criteria. Nine studies included hypertension as an outcome variable; fifteen included obesity; thirteen included glucose or insulin; eight included lipids; and three included measures of inflammation. The existing literature on sleep and cardiovascular disease in children and adolescents is limited and relatively weak. Only one RCT was identified, and the overwhelming majority of studies had a high risk of bias. The strongest evidence of an association with sleep is with obesity, hypertension, and insulin sensitivity. Further research using more standardized methods and objective measures is needed to determine if a causal relationship truly exists between sleep and cardiovascular risk.

    Effective community-based interventions are available to control hypertension. It is important to determine the economics of these interventions. Peer-reviewed studies from January 1995 through December 2015 were screened. Interventions were categorized into educational interventions, self-monitoring interventions, and screening interventions. Incremental cost-effectiveness ratios were summarized by types of interventions. The review was conducted in 2016. Thirty-four articles were included in the review (16 from the U.S., 18 from other countries), including 25 on educational interventions, three on self-monitoring interventions, and six on screening interventions. In the U.S., five (31.3%) studies on educational interventions were cost saving. Among the studies that found the interventions cost effective, the median incremental costs were $62 (range, $40-$114) for 1-mmHg reduction in systolic blood pressure (SBP) and $13,986 (range, $6,683-$58,610) for 1 life-year gained. Outside the U.S., educational interventions cost from $0.62 (China) to $29 (Pakistan) for 1-mmHg reduction in SBP. Self-monitoring interventions, evaluated in the U.S. only, cost $727 for 1-mmHg reduction in SBP and $41,927 for 1 life-year gained. For 1 quality-adjusted life-year, screening interventions cost from $21,734 to $56,750 in the U.S., $613 to $5,637 in Australia, and $7,000 to $18,000 in China. Intervention costs to reduce 1 mmHg blood pressure or 1 quality-adjusted life-year were higher in the U.S. than in other countries. Most studies found that the three types of interventions were either cost effective or cost saving. Quality of economic studies should be improved to confirm the findings.

    Full Text Available Background: Interventions in workplace settings are considered to be cost-effective in preventing cardiovascular diseases. A systematic review was conducted to assess the prevalence of hypertension and the level of awareness and control among workers in West Africa. Design: A systematic search for studies on formal and informal sector workers aged ≥15 years in West Africa published between 1980 and September 2014 was undertaken using the Ovid Medline, Embase, PubMed, and Google Scholar databases. Clinical and obstetric studies and studies that did not report prevalence were excluded. Data on study settings, characteristics of workers, blood pressure (BP levels, prevalence of hypertension, and associated demographic factors were extracted. Results: A total of 45 studies from six countries were identified involving 30,727 formal and informal sector workers. In 40 studies with a common definition of hypertension, the prevalence ranged from 12.0% among automobile garage workers to 68.9% among traditional chiefs. In 15 of these studies, the prevalence exceeded 30%. Typically sedentary workers such as traders, bank workers, civil servants, and chiefs were at high risk. Among health care workers, the prevalence ranged from 17.5 to 37.5%. The prevalence increased with age and was higher among males and workers with higher socio-economic status. Complications of hypertension, co-morbidities, and clustering of risk factors were common. The crude prevalence of hypertension increased progressively from 12.9% in studies published in the 1980s to 34.4% in those published in 2010–2014. The proportion of hypertensives who were previously aware of their diagnosis, were on treatment or had their BP controlled was 19.6–84.0%, 0–79.2%, and 0–12.7%, respectively. Hypertensive subjects, including health workers, rarely checked their BP except when they were ill. Conclusions: There is a high prevalence of hypertension among West Africa's workforce, of which

    Adverse effects, treatment resistance and high costs associated with pharmacological treatment of hypertension have led to growing interest in non-pharmacological complementary therapies such as music interventions. This meta-analysis aims to provide an overview of reported evidence on the efficacy of music interventions in the treatment of hypertension. A systematic literature search was conducted for publications on the effect of music interventions on blood pressure in adult hypertensive subjects published between January 1990-June 2014. Randomized controlled trials with a follow-up duration ≥28 days were included. Blood pressure measures were pooled using inverse variance weighting. Of the 1689 abstracts reviewed, 10 randomized controlled trials were included. Random-effects pooling of the music intervention groups showed a trend toward a decrease in mean systolic blood pressure (SBP) from 144 mmHg(95 % CI:137-152) to 134 mmHg(95 % CI:124-144), and in mean diastolic blood pressure (DBP) from 84 mmHg(95 % CI:78-89) to 78 mmHg(95 % CI:73-84). Fixed-effect analysis of a subgroup of 3 trials with valid control groups showed a significant decrease in pooled mean SBP and DBP in both intervention and control groups. A comparison between music intervention groups and control groups was not possible due to unavailable measures of dispersion. This systematic review and meta-analysis revealed a trend towards a decrease in blood pressure in hypertensive patients who received music interventions, but failed to establish a cause-effect relationship between music interventions and blood pressure reduction. Considering the potential value of this safe, low-cost intervention, well-designed, high quality and sufficiently powered randomized studies assessing the efficacy of music interventions in the treatment of hypertension are warranted.

    Full Text Available Observational studies of the relationship between hyperuricemia and the incidence of hypertension are controversial. We conducted a systematic review and meta-analysis to assess the association and consistency between uric acid levels and the risk of hypertension development.We searched MEDLINE, EMBASE, CBM (Chinese Biomedicine Database through September 2013 and reference lists of retrieved studies to identify cohort studies and nested case-control studies with uric acid levels as exposure and incident hypertension as outcome variables. Two reviewers independently extracted data and assessed study quality using Newcastle-Ottawa Scale. Extracted information included study design, population, definition of hyperuricemia and hypertension, number of incident hypertension, effect sizes, and adjusted confounders. Pooled relative risks (RRs and corresponding 95% confidence intervals (CIs for the association between hyperuricemia and risk of hypertension were calculated using a random-effects model.We included 25 studies with 97,824 participants assessing the association between uric acid and incident hypertension in our meta-analysis. The quality of included studies is moderate to high. Random-effects meta-analysis showed that hyperuricemia was associated with a higher risk of incident hypertension, regardless of whether the effect size was adjusted or not, whether the data were categorical or continuous as 1 SD/1 mg/dl increase in uric acid level (unadjusted: RR = 1.73, 95% CI 1.46∼2.06 for categorical data, RR = 1.22, 95% CI 1.03∼1.45 for a 1 SD increase; adjusted: RR = 1.48, 95% CI 1.33∼1.65 for categorical data, RR = 1.15, 95% CI 1.06∼1.26 for a 1 mg/dl increase, and the risk is consistent in subgroup analyses and have a dose-response relationship.Hyperuricemia may modestly increase the risk of hypertension incidence, consistent with a dose-response relationship.

    AIM: To describe the pathophysiology, clinical presentation, natural history, and therapy of portal hypertensive gastropathy (PHG) based on a systematic literature review. METHODS: Computerized search of the literature was performed via PubMed using the following medical subject headings or keywords: “portal” and “gastropathy”; or “portal” and “hypertensive”; or “congestive” and “gastropathy”; or “congestive” and “gastroenteropathy”. The following criteria were applied for study inclusion: Publication in peer-reviewed journals, and publication since 1980. Articles were independently evaluated by each author and selected for inclusion by consensus after discussion based on the following criteria: Well-designed, prospective trials; recent studies; large study populations; and study emphasis on PHG. RESULTS: PHG is diagnosed by characteristic endoscopic findings of small polygonal areas of variable erythema surrounded by a pale, reticular border in a mosaic pattern in the gastric fundus/body in a patient with cirrhotic or non-cirrhotic portal hypertension. Histologic findings include capillary and venule dilatation, congestion, and tortuosity, without vascular fibrin thrombi or inflammatory cells in gastric submucosa. PHG is differentiated from gastric antral vascular ectasia by a different endoscopic appearance. The etiology of PHG is inadequately understood. Portal hypertension is necessary but insufficient to develop PHG because many patients have portal hypertension without PHG. PHG increases in frequency with more severe portal hypertension, advanced liver disease, longer liver disease duration, presence of esophageal varices, and endoscopic variceal obliteration. PHG pathogenesis is related to a hyperdynamic circulation, induced by portal hypertension, characterized by increased intrahepatic resistance to flow, increased splanchnic flow, increased total gastric flow, and most likely decreased gastric mucosal flow.

    Therapeutic inertia has been defined as the failure of health-care provider to initiate or intensify therapy when therapeutic goals are not reached. It is regarded as a major cause of uncontrolled hypertension. The exploration of its causes and the interventions to reduce it are plagued by unclear conceptualizations and hypothesized mechanisms. We therefore systematically searched the literature for definitions and discussions on the concept of therapeutic inertia in hypertension in primary care, to try and form an operational definition. A systematic review of all types of publications related to clinical inertia in hypertension was performed. Medline, EMbase, PsycInfo, the Cochrane library and databases, BDSP, CRD and NGC were searched from the start of their databases to June 2013. Articles were selected independently by two authors on the basis of their conceptual content, without other eligibility criteria or formal quality appraisal. Qualitative data were extracted independently by two teams of authors. Data were analyzed using a constant comparative qualitative method. The final selection included 89 articles. 112 codes were grouped in 4 categories: terms and definitions (semantics), "who" (physician, patient or system), "how and why" (mechanisms and reasons), and "appropriateness". Regarding each of these categories, a number of contradictory assertions were found, most of them relying on little or no empirical data. Overall, the limits of what should be considered as inertia were not clear. A number of authors insisted that what was considered deleterious inertia might in fact be appropriate care, depending on the situation. Our data analysis revealed a major lack of conceptualization of therapeutic inertia in hypertension and important discrepancies regarding its possible causes, mechanisms and outcomes. The concept should be split in two parts: appropriate inaction and inappropriate inertia. The development of consensual and operational definitions

    Clinical Inertia is defined as "failure of health care providers to initiate or intensify therapy according to current guidelines". This phenomenon is gaining increasing attention as a major cause of clinicians' failure to adequately manage hypertension, thus leading to an increased incidence of cardiovascular events. We performed a systematic review and meta-analysis of randomized controlled trials to determine whether interventions aimed at reducing clinical inertia in the pharmacological treatment of hypertension improve blood pressure (BP) control. MEDLINE, Embase, and Cochrane Database of Systematic Reviews were searched from the start of their database until October 3, 2017 for the MESH terms "Hypertension" or "Blood Pressure", their subheadings, and the keywords "Therapeutic Inertia" or "Clinical Inertia". Studies were included if they addressed pharmacologic hypertension management, clinical inertia, were randomized controlled trials, reported an outcome describing prescriber behavior, and were available in English. Data for the included studies was extracted by two independent observers. Quality of studies was analyzed using the Cochrane Risk of Bias Assessment. Data was pooled for statistical analysis using both fixed- and random-effects models. The primary study outcome was the percentage of patients achieving blood pressure control as defined by the Joint National Committee guidelines or study authors. Of 474 citations identified, ten met inclusion criteria comprising a total of 26,871 patients, and eight were selected for meta-analysis. Interventions included Physician Education, Physician Reminders, Patient Education, Patient Reminders, Ambulatory BP Monitoring, Digital Medication Offerings, Physician Peer Visits, and Pharmacist-led Counselling. Pooled event rates revealed more patients with controlled BP in the intervention group versus control (55%, 95% CI 46-63% versus 45%, 95% CI 37-53%) and interventions significantly improved the odds of BP

    Childhood interstitial lung disease (chILD) comprises a wide heterogeneous group of rare parenchymal lung disorders associated with substantial morbidity and mortality. Pulmonary hypertension is a common comorbidity in adults with interstitial lung disease (ILD) and associated with poor survival. We aimed to systematically review the literature regarding the occurrence of pulmonary hypertension (PH) in chILD, its effect on prognosis and healthcare use, and its treatment in clinical practice. Searches of PubMed and EMBASE databases (up to February 2016), and American Thoracic Society conference abstracts (2009-2015) were conducted using relevant keywords. References from selected articles and review papers were scanned to identify further relevant articles. A total of 20 articles were included; estimates of PH in chILD ranged from 1% to 64% with estimates among specific chILD entities ranging from 0% to 43%. Comparisons between studies were limited by differences in the study populations, including the size, age range, and heterogeneous composition of the ILD case series in terms of the nature and severity of the clinical entities, and also the methods used to diagnose PH. Three studies found that among patients with chILD, those with PH had a significantly higher risk (up to sevenfold) of death compared with those without PH. Information on the treatment of pulmonary hypertension in chILD or the effect of PH on healthcare use was not available. Data on the use and effectiveness of treatments for pulmonary hypertension in chILD are required to address this area of unmet need.

    Full Text Available ABSTRACT OBJECTIVE To estimate the prevalence of hypertension among adolescent Brazilian students. METHODS A systematic review of school-based cross-sectional studies was conducted. The articles were searched in the databases MEDLINE, Embase, Scopus, LILACS, SciELO, Web of Science, CAPES thesis database and Trip Database. In addition, we examined the lists of references of relevant studies to identify potentially eligible articles. No restrictions regarding publication date, language, or status applied. The studies were selected by two independent evaluators, who also extracted the data and assessed the methodological quality following eight criteria related to sampling, measuring blood pressure, and presenting results. The meta-analysis was calculated using a random effects model and analyses were performed to investigate heterogeneity. RESULTS We retrieved 1,577 articles from the search and included 22 in the review. The included articles corresponded to 14,115 adolescents, 51.2% (n = 7,230 female. We observed a variety of techniques, equipment, and references used. The prevalence of hypertension was 8.0% (95%CI 5.0–11.0; I2 = 97.6%, 9.3% (95%CI 5.6–13.6; I2 = 96.4% in males and 6.5% (95%CI 4.2–9.1; I2 = 94.2% in females. The meta-regression failed to identify the causes of the heterogeneity among studies. CONCLUSIONS Despite the differences found in the methodologies of the included studies, the results of this systematic review indicate that hypertension is prevalent in the Brazilian adolescent school population. For future investigations, we suggest the standardization of techniques, equipment, and references, aiming at improving the methodological quality of the studies.

    Hypertension among HIV-positive populations has emerged as a new threat to the health and well being of people living with HIV, particularly among those receiving antiretroviral therapy. We reviewed the global evidence on the burden of disease (including prevalence and incidence), determinants of hypertension among HIV-positive populations, and the pharmacological management of hypertension in HIV-positive patients. We systematically searched PubMed-MEDLINE and EMBASE from January 2000 through February 2015 for relevant studies and traced their citations through the ISI Web of Science. We also searched the websites of the World Health Organisation, the International Society of Hypertension, and the International AIDS Society and constructed a narrative data synthesis. Hypertension is common in HIV-positive populations, with prevalence estimates ranging from 4.7 to 54.4% in high-income countries, and from 8.7 to 45.9% in low- and middle-income countries. The role of HIV-specific factors including disease severity, duration of disease, and treatments on the presence of hypertension in HIV-positive patients is reported, but patterns remain unclear. The clinical management of hypertension in HIV-positive patients is similar to those with hypertension in the general population; however, additional considerations should be given to potential drug interactions between antihypertensive agents and antiretroviral drugs to inform the clinician's selection of these therapies. Hypertension is common in HIV-positive populations and remains an important comorbidity affecting mortality outcomes. Further research examining the development of hypertension and its associated care in HIV-positive patients is required to optimize management of the dual conditions.

    We estimated hypertension and diabetes prevalence among US homeless adults compared with the general population, and investigated prevalence trends. We systematically searched 5 databases for published studies (1980–2014) that included hypertension or diabetes prevalence for US homeless adults, pooled disease prevalence, and explored heterogeneity sources. We used the National Health Interview Survey for comparison. We included data from 97 366 homeless adults. The pooled prevalence of self-reported hypertension was 27.0% (95% confidence interval = 23.8%, 29.9%; n = 43 studies) and of diabetes was 8.0% (95% confidence interval = 6.8%, 9.2%; n = 39 studies). We found no difference in hypertension or diabetes prevalence between the homeless and general population. Additional health care and housing resources are needed to meet the significant, growing burden of chronic disease in the homeless population. PMID:25521899

  14. Compliance with the Dietary Approaches to Stop Hypertension (DASH diet: a systematic review.

    Full Text Available BACKGROUND: The Dietary Approaches to Stop Hypertension (DASH diet has been recognized as effective to lower blood pressure in feeding trials, but compliance with the diet must be persistent to maximize health benefits in clinical practice. This paper reports a systematic review of the latest evidence on the method to assess DASH compliance and the corresponding patients' compliance in interventional settings. METHODS: The databases including MEDLINE, EBM Reviews, EMBASE, and CINAHL Plus were searched for original research studies published in the period of January 1992-December 2012 that evaluated compliance with DASH diet. Studies written in English language, with DASH intervention, with complete documentation of the degree of DASH compliance and the assessment method used were included in this review. The search terms included: dietary approaches to stop hypertension, DASH, compliance, adherence, consistency, and concordance. RESULTS: Nine studies were included. Different types of interventions were identified, ranging from feeding trial to dietary counseling. These studies differed in the assessment methods used to evaluate DASH compliance, which included objective approaches like measurement of urinary excretion, and subjective approaches like dietary intake assessment for DASH target comparison and construction of DASH scoring systems. Compliance levels were lower in educational interventions than that of the original DASH feeding trial. CONCLUSIONS: To conclude, although no consensus existed regarding the best approach to assess DASH compliance, its suboptimal compliance warrants attention. This study implied a need to investigate effective approaches to sustain the DASH dietary pattern beyond counselling alone.

    Survival of humanity, on this planet, may depend, heavily, on coping with advancing technology of nuclear missiles. Let us consider critical alternatives of powerful governments: democracy, as an alternative to dictatorship. Democracy is based on free elections, as a government of the people, by the people and for the people. Democracy is a historical urgency, in the age of inter-continental nuclear missiles, computerized on a push-button, conceivably controllable by a very powerful, miscalculating and/or insane, dictator, capable of producing global nuclear holocaust, on our entire planet. Diplomacy, together with supporting activities, should be utilized, to help, in important steps, at this time, for achieving democracy in critical areas.

    Racial ethnic minorities are one of the fastest growing populations in Taiwan. In recent years, there has been an increase in literature addressing the efficacy of home blood-pressure (BP) management that uses telemedicine interventions in general healthcare and community settings. However, no study or systematic literature review has yet assessed the effectiveness of using telemedicine HTN interventions in Taiwan's indigenous, new-immigrant, and other minority populations. The purpose of the present paper is to review the current literature on the use of telemedicine interventions to assist HTN management among racial ethnic minorities. A comprehensive literature search was conducted for full-text articles that were published between January 2000 and December 2015 using the following databases: PubMed, WEB of Science, CINAHL (Cumulative Index to Nursing & Allied Health Literature), PsycINFO, Science Direct, ProQuest, Medline, Cochrane Library, National Dissertations and Theses, and airiti Library. The search used the following key search terms both alone and in combination: hypertension, blood pressure, management, telemedicine, telehealth, ehealth, and digital health. The studies were thoroughly assessed under the guidelines of Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA). A total of 6 articles met the criteria for using keywords related to racial ethnic minority populations and were used in the present review. Findings of this systematic review show that telemedicine interventions significantly improve HTN management. The intervention that combined home telemonitoring with culturally competent nurse counseling calls was identified as the best intervention for reducing BP. As the current literature on this topic is limited to African-Americans, more research is necessary to validate our findings. Future studies should target racial ethnic minorities in Taiwan in order to better understand how to provide culturally appropriate

    2014-01-01

    Full Text Available This systematic review aims to provide an update on pharmacological and interventional strategies for the treatment of pulmonary arterial hypertension in adults. Currently US Food and Drug Administration approved drugs including prostanoids, endothelin-receptor antagonists, phosphodiesterase type-5 inhibitors, and soluble guanylate-cyclase stimulators. These agents have transformed the prognosis for pulmonary arterial hypertension patients from symptomatic improvements in exercise tolerance ten years ago to delayed disease progression today. On the other hand, percutaneous balloon atrioseptostomy by using radiofrequency perforation, cutting balloon dilatation, or insertion of butterfly stents and pulmonary artery catheter-based denervation, both associated with very low rate of major complications and death, should be considered in combination with specific drugs at an earlier stage rather than late in the progression of pulmonary arterial hypertension and before the occurrence of overt right-sided heart failure.

    Pulmonary arterial hypertension (PAH) complicates the course of systemic sclerosis (SSc) and is associated with poor prognosis. The elevation of systolic pulmonary arterial pressure (sPAP) during exercise in patients with SSc with normal resting haemodynamics may anticipate the development of PAH. Exercise echocardiography (ExEcho) has been proposed as a useful technique to identify exercise-induced increases in sPAP, but it is unclear how to clinically interpret these findings. In this systematic review, we summarize the available evidence on the role of exercise echocardiography to estimate exercise-induced elevations in pulmonary and left heart filling pressures in patients with systemic sclerosis. We conducted a systematic review of the literature using MEDLINE, Cochrane Library and Web of Knowledge, using the vocabulary terms: ('systemic sclerosis' OR 'scleroderma') AND ('exercise echocardiography') AND ('pulmonary hypertension'). Studies including patients with SSc without a prior diagnosis of PAH, and subjected to exercise echocardiography were included. All searches were limited to English and were augmented by review of bibliographic references from the included studies. The quality of evidence was assessed by the Effective Public Health Practice Project system. We identified 15 studies enrolling 1242 patients, who were mostly middle-aged and female. Several exercise methods were used (cycloergometer, treadmill and Master's two step), with different protocols and positions (supine, semi-supine, upright); definition of a positive test also varied widely. Resting estimated sPAP levels varied from 18 to 35 mm Hg, all in the normal range. The weighted means for estimated sPAP were 22.2 ± 2.9 mmHg at rest and 43.0 ± 4.3 mmHg on exercise; more than half of the studies reported mean exercise sPAP ≥40 mmHg. The assessment of left ventricular diastolic function on peak exercise was reported in a minority of studies; however, when assessed, surrogate

    Pulmonary hypertension is common in patients with chronic kidney disease (CKD) and end-stage renal disease (ESRD) and may be associated with poor outcomes. The magnitude of the association between pulmonary hypertension and mortality is uncertain due to the small size and variable findings of observational studies. Systematic review and meta-analysis of observational studies using subgroup analyses and metaregression. Patients with ESRD or earlier stages of CKD. Observational studies reporting clinical outcomes in patients with co-existing pulmonary hypertension and CKD or ESRD identified using a systematic search of PubMed and Embase. Pulmonary hypertension diagnosed by Doppler echocardiography. All-cause mortality, cardiovascular mortality, and cardiovascular events. 16 studies, with 7,112 patients with an overall pulmonary hypertension prevalence of 23%, were included. Pulmonary hypertension was associated with increased risk for all-cause mortality among patients with CKD (relative risk [RR], 1.44; 95% CI, 1.17-1.76), with ESRD receiving maintenance dialysis (RR, 2.32; 95% CI, 1.91-2.83), and with a functioning kidney transplant (RR, 2.08; 95% CI, 1.35-3.20). Pulmonary hypertension was associated with increased risk for cardiovascular events in patients with CKD (RR, 1.67; 95% CI, 1.07-2.60) and ESRD receiving dialysis (RR, 2.33; 95% CI, 1.76-3.08). There was an association between pulmonary hypertension and increased risk for cardiovascular mortality in patients with CKD or ESRD (RR, 2.20; 95% CI, 1.53-3.15). Heterogeneity of included studies, possibility of residual confounding, unavailability of individual patient-level data, and possibility of outcome reporting bias. Pulmonary hypertension is associated with a substantially increased risk for death and cardiovascular events in patients with CKD and ESRD. Risk is higher in patients with ESRD receiving dialysis compared with patients with CKD stages 1 to 5. Understanding the effect of interventions to lower

    Pairwise meta-analyses have shown beneficial effects of individual dietary approaches on blood pressure but their comparative effects have not been established. Therefore we performed a systematic review of different dietary intervention trials and estimated the aggregate blood pressure effects through network meta-analysis including hypertensive and pre-hypertensive patients. PubMed, Cochrane CENTRAL, and Google Scholar were searched until June 2017. The inclusion criteria were defined as follows: i) Randomized trial with a dietary approach; ii) hypertensive and pre-hypertensive adult patients; and iii) minimum intervention period of 12 weeks. In order to determine the pooled effect of each intervention relative to each of the other intervention for both diastolic and systolic blood pressure (SBP and DBP), random effects network meta-analysis was performed. A total of 67 trials comparing 13 dietary approaches (DASH, low-fat, moderate-carbohydrate, high-protein, low-carbohydrate, Mediterranean, Palaeolithic, vegetarian, low-GI/GL, low-sodium, Nordic, Tibetan, and control) enrolling 17,230 participants were included. In the network meta-analysis, the DASH, Mediterranean, low-carbohydrate, Palaeolithic, high-protein, low-glycaemic index, low-sodium, and low-fat dietary approaches were significantly more effective in reducing SBP (-8.73 to -2.32 mmHg) and DBP (-4.85 to -1.27 mmHg) compared to a control diet. According to the SUCRAs, the DASH diet was ranked the most effective dietary approach in reducing SBP (90%) and DBP (91%), followed by the Palaeolithic, and the low-carbohydrate diet (ranked 3rd for SBP) or the Mediterranean diet (ranked 3rd for DBP). For most comparisons, the credibility of evidence was rated very low to moderate, with the exception for the DASH vs. the low-fat dietary approach for which the quality of evidence was rated high. The present network meta-analysis suggests that the DASH dietary approach might be the most effective dietary measure

    Despite the introduction of targeted therapies in pediatric pulmonary arterial hypertension (PAH), prognosis remains poor. For the definition of treatment strategies and guidelines, there is a high need for an evidence-based recapitulation of prognostic factors. The aim of this study was to identify and evaluate prognostic factors in pediatric PAH by a systematic review of the literature and to summarize the prognostic value of currently reported prognostic factors using meta-analysis. Medline, EMBASE and Cochrane Library were searched on April 1st 2014 to identify original studies that described predictors of mortality or lung-transplantation exclusively in children with PAH. 1053 citations were identified, of which 25 were included for further analysis. Hazard ratios (HR) and 95% confidence intervals were extracted from the papers. For variables studied in at least three non-overlapping cohorts, a combined HR was calculated using random-effects meta-analysis. WHO functional class (WHO-FC, HR 2.7), (N-terminal pro-) brain natriuretic peptide ([NT-pro]BNP, HR 3.2), mean right atrial pressure (mRAP, HR 1.1), cardiac index (HR 0.7), indexed pulmonary vascular resistance (PVRi, HR 1.3) and acute vasodilator response (HR 0.3) were identified as significant prognostic factors (p ≤ 0.001). This systematic review combined with separate meta-analyses shows that WHO-FC, (NT-pro)BNP, mRAP, PVRi, cardiac index and acute vasodilator response are consistently reported prognostic factors for outcome in pediatric PAH. These variables are useful clinical tools to assess prognosis and should be incorporated in treatment strategies and guidelines for children with PAH. Copyright © 2015 Elsevier Ireland Ltd.

To clarify, if this complication was associated to use of standard SO (SSO versus heavy SO (HSO, we performed a systematic review and meta-analysis of comparative study between two kind of SO (standard or light vs. heavy for the treatment of RD and macular hole, without restriction to study design. Materials and Methods: The methodological quality of two randomized clinical trials (RCTs were evaluated using the criteria given in the Cochrane Handbook for Systematic Reviews of Intervention, while three non-RCTs were assessed with the Newcastle-Ottawa Scale and Strengthening the Reporting of Observational Studies in Epidemiology checklists. We calculated Mantel-Haenszel risk ratio (RR with 95% confidence intervals (95% CIs. The primary outcome was the rate of patients with OH treated with SSO compared to HSO. Results: There were a higher number of rates of OH in HSO compared to SSO. This difference was statistically significant with the fixed effect model (Mantel-Haenszel RR; 1.55; 95% CI, 1.06-2.28; P = 0.02 while there was not significative difference with the random effect model (Mantel-Haenszel RR; 1.51; 95% CI, 0.98-2.33; P = 0.06. Conclusion: We noted a trend that points out a higher OH rate in HSO group compared to SSO, but this finding, due to the small size and variable design of studies, needs to be confirmed in well-designed and large size RCTs.

    This systematic review applied meta-analytic procedures to synthesize medication adherence interventions that focus on adults with hypertension. Comprehensive searching located trials with medication adherence behavior outcomes. Study sample, design, intervention characteristics, and outcomes were coded. Random-effects models were used in calculating standardized mean difference effect sizes. Moderator analyses were conducted using meta-analytic analogues of ANOVA and regression to explore associations between effect sizes and sample, design, and intervention characteristics. Effect sizes were calculated for 112 eligible treatment-vs.-control group outcome comparisons of 34,272 subjects. The overall standardized mean difference effect size between treatment and control subjects was 0.300. Exploratory moderator analyses revealed interventions were most effective among female, older, and moderate- or high-income participants. The most promising intervention components were those linking adherence behavior with habits, giving adherence feedback to patients, self-monitoring of blood pressure, using pill boxes and other special packaging, and motivational interviewing. The most effective interventions employed multiple components and were delivered over many days. Future research should strive for minimizing risks of bias common in this literature, especially avoiding self-report adherence measures.

    Hypertension is increasingly common in sub-Saharan Africa, and rates of hypertension control are low. Use of traditional herbal medicines (THM) is common among adults in sub-Saharan Africa and may affect hypertension therapy. We searched Ovid MEDLINE, Ovid EMBASE, and Web of Knowledge in June 2013 to find studies about THM use among hypertensive patients living in sub-Saharan Africa. Two independent reviewers evaluated titles and abstracts. Qualifying references were reviewed in full text. Data were extracted using a standardized questionnaire. Four hundred and eighty-one references were retrieved, and four articles from two countries met criteria for inclusion. The prevalence of THM use was 25-65% (average 38.6%). THM was the most common type of complementary and alternative medicines used by patients (86.7-96.6%). Among THM users, 47.5% concomitantly used both allopathic medicine and THM. Increased age (psupernatural cause of hypertension (RR 2.11), and family history of hypertension (OR 1.78) were positively associated with THM use, while belief that hypertension is preventable was negatively associated with THM use (OR 0.57). More than one-third of adults with hypertension in sub-Saharan Africa use THM. Half of these patients use THM concurrently with allopathic medicine. Healthcare workers in sub-Saharan Africa must discuss THM use with their hypertensive patients. More research is urgently needed to define the impact of THM use on hypertension control and outcomes in sub-Saharan Africa.

    Full Text Available Abstract Background Severe mental illnesses (SMI may be independently associated with cardiovascular risk factors and the metabolic syndrome. We aimed to systematically assess studies that compared diabetes, dyslipidaemia, hypertension and metabolic syndrome in people with and without SMI. Methods We systematically searched MEDLINE, EMBASE, CINAHL & PsycINFO. We hand searched reference lists of key articles. We employed three search main themes: SMI, cardiovascular disease, and each cardiovascular risk factor. We selected cross-sectional, case control, cohort or intervention studies comparing one or more risk factor in both SMI and a reference group. We excluded studies without any reference group. We extracted data on: study design, cardiovascular risk factor(s and their measurement, diagnosis of SMI, study setting, sampling method, nature of comparison group and data on key risk factors. Results Of 14592 citations, 134 papers met criteria and 36 were finally included. 26 reported on diabetes, 12 hypertension, 11 dyslipidaemia, and 4 metabolic syndrome. Most studies were cross sectional, small and several lacked comparison data suitable for extraction. Meta-analysis was possible for diabetes, cholesterol and hypertension; revealing a pooled risk ratio of 1.70 (1.21 to 2.37 for diabetes and 1.11 (0.91 to 1.35 of hypertension. Restricting SMI to schizophreniform illnesses yielded a pooled risk ratio for diabetes of 1.87 (1.68 to 2.09. Total cholesterol was not higher in people with SMI (Standardized Mean Difference -0.10 (-0.55 to 0.36 and there were inconsistent data on HDL, LDL and triglycerides with some, but not all, reporting lower levels of HDL cholesterol and raised triglyceride levels. Metabolic syndrome appeared more common in SMI. Conclusion Diabetes (but not hypertension is more common in SMI. Data on other risk factors were limited by poor quality or inconsistent research findings, but a small number of studies show greater prevalence

    Hypertensive crises are divided into hypertensive urgencies and emergencies. Together they form a heterogeneous group of acute hypertensive disorders depending on the presence or type of target organs involved. Despite better treatment options for hypertension, hypertensive crisis and its associated complications remain relatively common. In the Netherlands the number of patients starting renal replacement therapy because of 'malignant hypertension' has increased in the past two decades. In 2003, the first Dutch guideline on hypertensive crisis was released to allow a standardised evidence-based approach for patients presenting with a hypertensive crisis. In this paper we give an overview of the current management of hypertensive crisis and discuss several important changes incorporated in the 2010 revision. These changes include a modification in terminology replacing 'malignant hypertension' with 'hypertensive crisis with retinopathy and reclassification of hypertensive crisis with retinopathy under hypertensive emergencies instead of urgencies. With regard to the treatment of hypertensive emergencies, nicardipine instead of nitroprusside or labetalol is favoured for the management of perioperative hypertension, whereas labetalol has become the drug of choice for the treatment of hypertension associated with pre-eclampsia. For the treatment of hypertensive urgencies, oral administration of nifedipine retard instead of captopril is recommended as first-line therapy. In addition, a section on the management of hypertensive emergencies according to the type of target organ involved has been added. Efforts to increase the awareness and treatment of hypertension in the population at large may lower the incidence of hypertensive crisis and its complications.

    Gestational hypertensive disorders, including gestational hypertension and preeclampsia, are one of the leading causes of maternal morbidity and mortality. The aim of our study was to evaluate the effect of exercise during pregnancy on the risk of gestational hypertensive disorders. Electronic databases were searched from their inception to February 2017. Selection criteria included only randomized controlled trials of uncomplicated pregnant women assigned before 23 weeks to an aerobic exercise regimen or not. The summary measures were reported as relative risk with 95% confidence intervals. The primary outcome was the incidence of gestational hypertensive disorders, defined as either gestational hypertension or preeclampsia. Seventeen trials, including 5075 pregnant women, were analyzed. Of them, seven contributed data to quantitative meta-analysis for the primary outcome. Women who were randomized in early pregnancy to aerobic exercise for about 30-60 min two to seven times per week had a significant lower incidence of gestational hypertensive disorders (5.9% vs. 8.5%; relative risk 0.70, 95% confidence interval 0.53-0.83; seven studies, 2517 participants), specifically a lower incidence of gestational hypertension (2.5% vs. 4.6%; relative risk 0.54, 95% confidence interval 0.40-0.74; 16 studies, 4641 participants) compared with controls. The incidence of preeclampsia (2.3% vs. 2.8%; relative risk 0.79, 95% confidence interval 0.45-1.38; six studies, 2230 participants) was similar in both groups. The incidence of cesarean delivery was decreased by 16% in the exercise group. Aerobic exercise for about 30-60 min two to seven times per week during pregnancy, as compared with being more sedentary, is associated with a significantly reduced risk of gestational hypertensive disorders overall, gestational hypertension, and cesarean delivery. © 2017 Nordic Federation of Societies of Obstetrics and Gynecology.

    Hypertension is a common global health problem with significant mortality and morbidity. Hibiscus sabdariffa is a plant known in many countries and is consumed as hot and cold drinks In addition to its use in folk medicine; it has been suggested as treatment for many conditions including hypertension. The objectives of this review were to examine the evidence of effectiveness and safety of hibiscus in the treatment of hypertension. We searched several medical databases (MEDLINE, EMBASE, CINAHL, Cochrane Central Register of Controlled Trials, and the specialized register of the Cochrane Hypertension Group and the general engine Google) to January 2009. We included randomized controlled trials that had examined Hibiscus's effectiveness and safety in the treatment of primary hypertension in adults. Two authors independently selected the trials for the review, extracted the data, and critically appraised the included studies. Four trials, with a total of 390 patients, met our inclusion criteria. Two studies compared Hibiscus sabdariffa to black tea; one study compared it to captopril and one to lisinopril. The studies found that Hibiscus had greater blood pressure reduction than tea but less than the ACE-inhibitors. However, all studies, except one, were short term and of poor quality with a Jadad scoring of Hibiscus sabdariffa for the treatment of primary hypertension in adults. Copyright 2009 Elsevier GmbH.

    Full Text Available Hypertension is a leading global health threat and a major cardiovascular disease. Since clinical interventions are effective in delaying the disease progression from prehypertension to hypertension, diagnostic prediction models to identify patient populations at high risk for hypertension are imperative.Both PubMed and Embase databases were searched for eligible reports of either prediction models or risk scores of hypertension. The study data were collected, including risk factors, statistic methods, characteristics of study design and participants, performance measurement, etc.From the searched literature, 26 studies reporting 48 prediction models were selected. Among them, 20 reports studied the established models using traditional risk factors, such as body mass index (BMI, age, smoking, blood pressure (BP level, parental history of hypertension, and biochemical factors, whereas 6 reports used genetic risk score (GRS as the prediction factor. AUC ranged from 0.64 to 0.97, and C-statistic ranged from 60% to 90%.The traditional models are still the predominant risk prediction models for hypertension, but recently, more models have begun to incorporate genetic factors as part of their model predictors. However, these genetic predictors need to be well selected. The current reported models have acceptable to good discrimination and calibration ability, but whether the models can be applied in clinical practice still needs more validation and adjustment.

    Objective To analyze and compare the usefulness of hypertension management APPs released in the Chinese market; to understand the general situations, characteristics, problems, and trends in hypertension management mHealth APPs; and to identify the gaps between mainland China products and non-mainland China products with the aim to provide recommendations for developers in industry and assist hypertensive patients in selecting suitable APPs. Methods The hypertension management APPs available by October 2016 in China were analyzed from the perspective of data items and function usefulness. Sample sets were determined through PRISMA. An evaluation item set was developed based on the usability framework of TURF and the Chinese Guideline for the Management of Hypertension and used to quantitatively analyze the functionalities and data items collected from the sample APPs from the perspective of designers, users, and activity models. Results Among the 73 Chinese-supported APPs, none of the hypertension management APPs could fully cover the usefulness item set (mean = 37.4%). Regarding the use of mobile terminal hardware, only cameras and positioning sensors are commonly used in information collection. Regarding the data items and services provided, the most commonly collected data are “demographic information” (88% versus 100%) and “vital signs” (76% versus 100%), but APPs developed in mainland China and non-mainland China provided significantly different services and profit-making patterns. Regarding data security and privacy protection, the APPs from mainland China provided far lower usefulness (31% versus 56%). Conclusions mHealth APPs can promptly and efficiently acquire sign-related data by improving the professionality and scientificity of data about healthy living habits. APPs also improve the preventive usefulness of the collected data and bring about new opportunities for the management and control of hypertension. Other important research trends

    The aim of this systematic review and meta-analysis was to summarize the evidence on the relation of the intakes of 12 major food groups, including whole grains, refined grains, vegetables, fruits, nuts, legumes, eggs, dairy, fish, red meat, processed meat, and sugar-sweetened beverages (SSBs) with the risk of hypertension. PubMed, Scopus, and Web of Science were searched systematically until June 2017 for prospective studies having quantitatively investigated the above-mentioned foods. We conducted meta-analysis on the highest compared with the lowest intake categories and linear and nonlinear dose-response meta-analyses to analyze the association. Summary RRs and 95% CIs were estimated by using a random-effects model. Overall, 28 reports were included in the meta-analysis. An inverse association for the risk of hypertension was observed for 30 g whole grains/d (RR: 0.92; 95% CI: 0.87, 0.98), 100 g fruits/d (RR: 0.97; 95% CI: 0.96, 0.99), 28 g nuts/d (RR: 0.70; 95% CI: 0.45, 1.08), and 200 g dairy/d (RR: 0.95; 95% CI: 0.94, 0.97), whereas a positive association for 100 g red meat/d (RR: 1.14; 95% CI: 1.02, 1.28), 50 g processed meat/d (RR: 1.12; 95% CI: 1.00, 1.26), and 250 mL SSB/d (RR: 1.07; 95% CI: 1.04, 1.10) was seen in the linear dose-response meta-analysis. Indication for nonlinear relations of the intakes of whole grains, fruits, fish, and processed meats with the risk of hypertension was detected. In summary, this comprehensive dose-response meta-analysis of 28 reports identified optimal intakes of whole grains, fruits, nuts, legumes, dairy, red and processed meats, and SSBs related to the risk of hypertension. These findings need to be seen under the light of very-low to low quality of meta-evidence. However, the findings support the current dietary guidelines in the prevention of hypertension. © 2017 American Society for Nutrition.

    2017-10-24

    Hypertension is a chronic condition that affects adults of all ages. In the United States, 1 in 3 adults has hypertension, and about half of the hypertensive population is adequately controlled. This costs the nation US $46 billion each year in health care services and medications required for treatment and missed workdays. Finding easier ways of managing this condition is key to successful treatment. A solution to reduce visits to physicians for chronic conditions is to utilize telemedicine. Research is limited on the effects of utilizing telemedicine in health care facilities. There are potential benefits for implementing telemedicine programs with patients dealing with chronic conditions. The purpose of this review was to weigh the facilitators against the barriers for implementing telemedicine. Searches were methodically conducted in the Cumulative Index to Nursing and Allied Health Literature Complete (CINAHL Complete) via Elton B Stephens Company (EBSCO) and PubMed (which queries MEDLINE) to collect information about self-management of hypertension through the use of telemedicine. Results identify facilitators and barriers corresponding to the implementation of self-management of hypertension using telemedicine. The most common facilitators include increased access, increase in health and quality, patient knowledge and involvement, technology growth with remote monitoring, cost-effectiveness, and increased convenience/ease. The most prevalent barriers include lack of evidence, self-management difficult to maintain, no long-term results/more areas to address, and long-term added workload commitment. This review guides health care professionals in incorporating new practices and identifying the best methods to introduce telemedicine into their practices. Understanding the facilitators and barriers to implementation is important, as is understanding how these factors will impact a successful implementation of telemedicine in the area of self-management of

    Background The prevalence of hypertension in emerging nations was scarcely described to date. In Brazil, many population-based surveys evaluated the prevalence in cities throughout the country. However, there is no population-based nationwide study of prevalence of hypertension. In this study, we estimated the prevalence of hypertension for the country and analyzed the trends for the last three decades. Methods Cross-sectional and cohort studies conducted from 1980 to 2010 were independently identified by two reviewers, without language restriction, in the PubMed, Embase, LILACS, and Scielo electronic databases. Unpublished studies were identified in the Brazilian electronic database of theses and in annals of Cardiology congresses and meetings. In total, 40 studies were selected, comprising 122,018 individuals. Results Summary estimates of prevalence by the former WHO criteria (BP≥160/95 mmHg) in the 1980’s and 1990’s were 23.6% (95% CI 17.3–31.4%) and 19.6% (16.4–23.3%) respectively. The prevalence of hypertension by the JNC criteria (BP≥140/90 mmHg) in the 1980’s, 1990’s and 2000’s were 36.1% (95% CI 28.7–44.2%), 32.9% (29.9–36.0%), and 28.7% (26.2–31.4%), respectively (P<0.001). In the 2000’s, the pooled prevalence estimates of self-reported hypertension on telephone inquiries was 20.6% (19.0–22.4%), and of self-reported hypertension in home surveys was 25.2% (23.3–27.2%). Conclusions The prevalence of hypertension in Brazil seems to have diminished 6% in the last three decades, but it still is approximately 30%. Nationwide surveys by self-reporting by telephone interviews underestimate the real prevalence. Rates of blood pressure control decreased in the same period, corresponding currently to only one quarter of individuals with hypertension. PMID:23118964

    Research on relational aggression (indirect and social means of inflicting harm) has previously focused on adolescent populations. The current study extends this research by exploring both the frequency of perpetrating and being the target of relational aggression as it relates to alcohol use outcomes in a college population. Further, this study examines whether positive urgency (e.g., acting impulsively in response to positive emotions) and negative urgency (e.g., acting impulsively in response to negative emotions) moderate the relationship between relational aggression and alcohol outcomes. In this study, 245 college students (65.7% female) completed an online survey. Results indicated greater frequency of perpetrating relational aggression, higher levels of positive urgency, or higher levels of negative urgency was associated with more negative consequences. Further, negative urgency moderated the relationship between frequency of perpetrating aggression and consequences such that aggression was more strongly associated with consequences for those high in urgency. Counter to the adolescent literature, the frequency of being the target of aggression was not associated with more alcohol use. These findings suggest that perpetrators of relational aggression may be at particular risk for negative alcohol-related consequences when they act impulsively in response to negative, but not positive, emotions. These students may benefit from interventions exploring alternative ways to cope with negative emotions.

    Pulmonary hypertension complicates the clinical course of extremely preterm infants and is associated with bronchopulmonary dysplasia (BPD). However, prevalence, risk factors, and outcome of pulmonary hypertension in these infants are insufficiently known. This systematic review and meta-analysis aims to provide an up-to-date overview of available data on prevalence, risk factors, and outcome of pulmonary hypertension and to identify current knowledge gaps. Medline, EMBASE, and the Cochrane Library databases were searched in July 2017. Two authors reviewed titles/abstracts and full-texts. Eligible studies reported prevalence, patient characteristics or mortality of infants with/without pulmonary hypertension. Studies were excluded if they did not include extremely preterm infants. Only similar study samples (selected infants with BPD or infants both with/without BPD) were compared in the meta-analyses. Of 1829 unique articles identified, 25 were eligible for inclusion. Pulmonary hypertension was observed in infants with BPD (20%, 95% confidence interval [CI] 14, 25), but also in those without BPD (2%, 95% CI 0, 8). Infants with severe BPD were most at risk of pulmonary hypertension (risk ratio [RR] 2.7, 95% CI 1.7, 4.2). Infants with pulmonary hypertension were more at risk of mortality (RR 4.7, 95% CI 2.7, 8.3). Pulmonary hypertension occurs in particularly in infants with severe BPD, and increases risk of mortality. Due to selected study populations, heterogeneous pulmonary hypertension-definitions and poorly reported timing of pulmonary hypertension assessments, however, data available in current reports are insufficient to allow accurate assessment of true prevalence, risk factors, and time-related outcome. Prospective studies, with standardised methodology and follow-up are needed to determine these factors. © 2018 John Wiley & Sons Ltd.

    Effects of blood pressure reduction in persons with grade 1 hypertension are unclear. To investigate whether pharmacologic blood pressure reduction prevents cardiovascular events and deaths in persons with grade 1 hypertension. Trials included in the BPLTTC (Blood Pressure Lowering Treatment Trialists' Collaboration) and trials identified from a previous review and electronic database searches. Patients without cardiovascular disease with blood pressures in the grade 1 hypertension range (140 to 159/90 to 99 mm Hg) who were randomly assigned to an active (antihypertensive drug or more intensive regimen) or control (placebo or less intensive regimen) blood pressure-lowering regimen. Individual-patient data from BPLTTC trials and aggregate data from other trials were extracted. Risk of bias was assessed for all trials. Individual-patient data involved 10 comparisons from trials where most patients had diabetes, and aggregate data involved 3 comparisons from trials of patients without diabetes. The average blood pressure reduction was about 3.6/2.4 mm Hg. Over 5 years, odds ratios were 0.86 (95% CI, 0.74 to 1.01) for total cardiovascular events, 0.72 (CI, 0.55 to 0.94) for strokes, 0.91 (CI, 0.74 to 1.12) for coronary events, 0.80 (CI, 0.57 to 1.12) for heart failure, 0.75 (CI, 0.57 to 0.98) for cardiovascular deaths, and 0.78 (CI, 0.67 to 0.92) for total deaths. Results were similar in secondary analyses. Withdrawal from treatment due to adverse effects was more common in the active groups. Blood pressure reductions and numbers of events were small. Blood pressure-lowering therapy is likely to prevent stroke and death in patients with uncomplicated grade 1 hypertension.

    With the wide application of targeted drug therapies, the relevance of prognostic and predictive markers in patient selection has become increasingly important. Bevacizumab is commonly used in combination with chemotherapy in the treatment of metastatic colorectal cancer. However, there are currently no predictive or prognostic biomarkers for bevacizumab. Several clinical studies have evaluated bevacizumab-induced hypertension in patients with metastatic colorectal cancer. This meta-analysis was performed to better determine the association of bevacizumab-induced hypertension with outcome in patients with metastatic colorectal cancer, and to assess whether bevacizumab-induced hypertension can be used as a prognostic factor in these patients. We performed a systematic review and meta-analysis on seven published studies to investigate the relationship between hypertension and outcome of patients with metastatic colorectal cancer treated with bevacizumab. Our primary endpoint was progression-free survival (PFS). Secondary endpoints were overall survival (OS) and overall response rate (ORR). Hazard ratios (HRs) for PFS and OS were extracted from each trial, and the log of the relative risk ratio (RR) was estimated for ORR. The occurrence of bevacizumab-induced hypertension in patients was highly associated with improvements in PFS (HR = 0.57, 95% CI: 0.46-0.72; P hypertension. Bevacizumab-induced hypertension may represent a prognostic factor in patients with metastatic colorectal cancer.

    Urgency is the core symptom of the overactive bladder symptom complex, but the underlying mechanisms are not fully understood. To review clinical and experimental studies related to how bladder filling and urgency are sensed and what causes urgency and to discuss how this process affects potential therapeutic strategies. Review of published reports. The definition of urgency as a desire implies that it can only be assessed in cognitively intact patients and that animal studies have to rely on surrogate markers thereof, such as detrusor overactivity (DO); however, DO and urgency are not always associated. While the precise mechanisms of how urgency is sensed remain unclear, accumulating evidence suggests that they may differ from the physiologic sensation of bladder filling. Studies on the neurophysiology of urgency sensing are hampered by reliance on the surrogate marker DO. Functional brain imaging may help to understand the central neurophysiology, but, until now, it has not specifically focused on urgency. With regard to causes of urgency, multiple theories have been forwarded. While none of them has been proven, it should be noted that they are not mutually exclusive, and, in specific patients, different causes may be present. The development of improved therapeutic strategies against urgency will be helped by a better understanding of how urgency is perceived and the underlying causes. Rigorous use of existing definitions and the search for reliable surrogate markers will aid such attempts.

    The findings of prospective cohort studies are inconsistent regarding the association between dietary magnesium intake and serum magnesium concentration and the risk of hypertension. We aimed to review the evidence from prospective cohort studies and perform a dose-response meta-analysis to investigate the relationship between dietary magnesium intake and serum magnesium concentrations and the risk of hypertension. We searched systematically PubMed, EMBASE and the Cochrane Library databases from October 1951 through June 2016. Prospective cohort studies reporting effect estimates with 95% confidence intervals (CIs) for hypertension in more than two categories of dietary magnesium intake and/or serum magnesium concentrations were included. Random-effects models were used to combine the estimated effects. Nine articles (six on dietary magnesium intake, two on serum magnesium concentration and one on both) of ten cohort studies, including 20,119 cases of hypertension and 180,566 participates, were eligible for inclusion in the meta-analysis. We found an inverse association between dietary magnesium intake and the risk of hypertension [relative risk (RR) = 0.92; 95% CI: 0.86, 0.98] comparing the highest intake group with the lowest. A 100 mg/day increment in magnesium intake was associated with a 5% reduction in the risk of hypertension (RR = 0.95; 95% CI: 0.90, 1.00). The association of serum magnesium concentration with the risk of hypertension was marginally significant (RR = 0.91; 95% CI: 0.80, 1.02). Current evidence supports the inverse dose-response relationship between dietary magnesium intake and the risk of hypertension. However, the evidence about the relationship between serum magnesium concentration and hypertension is limited.

    The health of older persons has not been a major priority in many African countries. Hypertension is one of the common health problems of older persons. However, there is little information on the prevalence of hypertension in older adults in Africa. This is in spite of the fact that Africa has the highest age-standardized prevalence of hypertension in the world. We therefore present this protocol to conduct a systematic review and meta-analysis on the prevalence of hypertension and the level of its awareness among older persons living in Africa. Major databases (EMBASE, MEDLINE, Academic Search Complete, CINAHL, PsycINFO) and unpublished literature will be searched to identify population-based studies on hypertension in adults aged 50 years and older living in Africa. Eligible articles are those which use the 140/90-mmHg cutoff to diagnose hypertension and were published from 1980 to present. We will exclude subjects in restricted environments such as patients and refugees. Articles will be independently evaluated by two reviewers to determine if they meet the inclusion criteria. They will also evaluate the quality of included studies using a validated tool by Hoy and colleagues for prevalence studies. The main outcome is the prevalence of hypertension while the explanatory variables include demographic, socio-economic, dietary, lifestyle and behavioural factors. Effect sizes in bivariate and multivariate analyses will be presented as odds or prevalence ratios. We will explore for heterogeneity of the standard errors across the studies, and if appropriate, we will perform a meta-analysis using a random-effects model to present a summary estimate of the prevalence of hypertension in this population. The estimates of the prevalence, the risk factors and the level of awareness of hypertension could help in galvanizing efforts at prioritizing the cardiovascular health of older persons in Africa.

    Full Text Available BACKGROUND: Although the importance of detecting, treating, and controlling hypertension has been recognized for decades, the majority of patients with hypertension remain uncontrolled. The path from evidence to practice contains many potential barriers, but their role has not been reviewed systematically. This review aimed to synthesize and identify important barriers to hypertension control as reported by patients and healthcare providers. METHODS: Electronic databases MEDLINE, EMBASE and Global Health were searched systematically up to February 2013. Two reviewers independently selected eligible studies. Two reviewers categorized barriers based on a theoretical framework of behavior change. The theoretical framework suggests that a change in behavior requires a strong commitment to change [intention], the necessary skills and abilities to adopt the behavior [capability], and an absence of health system and support constraints. FINDINGS: Twenty-five qualitative studies and 44 quantitative studies met the inclusion criteria. In qualitative studies, health system barriers were most commonly discussed in studies of patients and health care providers. Quantitative studies identified disagreement with clinical recommendations as the most common barrier among health care providers. Quantitative studies of patients yielded different results: lack of knowledge was the most common barrier to hypertension awareness. Stress, anxiety and depression were most commonly reported as barriers that hindered or delayed adoption of a healthier lifestyle. In terms of hypertension treatment adherence, patients mostly reported forgetting to take their medication. Finally, priority setting barriers were most commonly reported by patients in terms of following up with their health care providers. CONCLUSIONS: This review identified a wide range of barriers facing patients and health care providers pursuing hypertension control, indicating the need for targeted multi

    Objective To determine the efficacy of acupuncture for hypertension. Method Seven electronic databases were searched on April 13, 2014 to include eligible randomized controlled trials (RCTs). Data were extracted and risk of bias was assessed. Subgroup analyses and meta- analysis were performed. Results 23 RCTs involving 1788 patients were included. Most trials had an unclear risk of bias regarding allocation concealment, blinding, incomplete outcome data and selective reporting. Compared with sham acupuncture plus medication, a meta-analysis of 2 trials revealed that acupuncture as an adjunct to medication was more effective on systolic (SBP) and diastolic (DBP) blood pressure change magnitude (n=170, SBP: mean difference (MD)= -7.47,95% confidence intervals (CI):-10.43 to -4.51,I2 =0%; DBP: -4.22,-6.26 to -2.18, 0%).A subgroup analysis of 4 trials also showed acupuncture combined with medication was superior to medication on efficacy rate (n=230, odds ratio (OR)=4.19, 95%CI: 1.65 to 10.67, I2 =0%). By contrast, compared with medication, acupuncture alone showed no significant effect on SBP /DBP after intervention and efficacy rate in the subgroup analysis. (7 trials with 510 patients, SBP: MD=-0.56, 95%CI:-3.02 to 1.89,I2 =60%; DBP: -1.01,-2.26 to 0.24, 23%; efficacy rate: 10 trials with 963 patients, OR=1.14, 95% CI: 0.70 to 1.85, I2 =54%).Adverse events were inadequately reported in most RCTs. Conclusion Our review provided evidence of acupuncture as an adjunctive therapy to medication for treating hypertension, while the evidence for acupuncture alone lowing BP is insufficient. The safety of acupuncture is uncertain due to the inadequate reporting of it. However, the current evidence might not be sufficiently robust against methodological flaws and significant heterogeneity of the included RCTs. Larger high-quality trials are required. PMID:26207806

    Hypertensive disorders of pregnancy (HDP, including gestational hypertension, preeclampsia, and eclampsia) have a substantial public health impact. Maternal exposure to high levels of air pollution may trigger HDP, but this association remains unclear. The objective of our report is to assess and quantify the association between maternal exposures to criteria air pollutants (ozone, carbon monoxide, nitrogen dioxide, sulfur dioxide, and particulate matter ≤ 10, 2.5 μm) on HDP risk. PubMed, EMBASE, MEDLINE, Current Contents, Global Health, and Cochrane were searched (last search: September, 2013). After a detailed screening of 270 studies, 10 studies were extracted. We conducted meta-analyses if a pollutant in a specific exposure window was reported by at least four studies. Using fixed- and random-effects models, odds ratios (ORs) and 95% CIs were calculated for each pollutant with specific increment of concentration. Increases in risks of HDP (OR per 10 ppb = 1.16; 95% CI, 1.03-1.30) and preeclampsia (OR per 10 ppb = 1.10; 95% CI, 1.03-1.17) were observed to be associated with exposure to NO2 during the entire pregnancy, and significant associations between HDP and exposure to CO (OR per 1 ppm = 1.79; 95% CI, 1.31-2.45) and O3 (OR per 10 ppb = 1.09; 95% CI, 1.05-1.13) during the first trimester were also observed. Our review suggests an association between ambient air pollution and HDP risk. Although the ORs were relatively low, the population-attributable fractions were not negligible given the ubiquitous nature of air pollution. PMID:25242883

    Since urgency is key to the overactive bladder syndrome, we have reviewed the mechanisms underlying how bladder filling and urgency are sensed, what causes urgency and how this relates to medical therapy. Review of published literature. As urgency can only be assessed in cognitively intact humans, mechanistic studies of urgency often rely on proxy or surrogate parameters, such as detrusor overactivity, but these may not necessarily be reliable. There is an increasing evidence base to suggest that the sensation of ‘urgency’ differs from the normal physiological urge to void upon bladder filling. While the relative roles of alterations in afferent processes, central nervous processing, efferent mechanisms and in intrinsic bladder smooth muscle function remain unclear, and not necessarily mutually exclusive, several lines of evidence support an important role for the latter. A better understanding of urgency and its causes may help to develop more effective treatments for voiding dysfunction.

    High blood pressure is a problem with elevated prevalence in the world population. The acute forms of presentation are "hypertensive crises," which represent a frequent cause for emergency room and primary care consultations. Hypertensive crises are divided into hypertensive emergencies and hypertensive urgencies, depending on whether or not there is acute damage to the target organ, respectively. Each situation has a different prognosis and treatment. More specifically, hypertensive emergencies are potentially serious and usually require rapid reductions in blood pressure, whereas hypertensive urgencies can be treated as outpatients by reducing blood pressure in hours or days. A significant number of patients who consult medical professionals regarding a hypertensive crisis do not have a prior diagnosis of hypertension; therefore, it is important to periodically monitor blood pressure levels in the community.

    Full Text Available Background: Results of previous research have identified the need for further investigation into the compliance with good practice guidelines for current decision-analytic modeling (DAM. Objective: To identify the extent to which recent model-based economic evaluations of interventions focused on lowering the blood pressure (BP of patients with hypertension conform to published guidelines for DAM in health care using a five-dimension framework developed to assess compliance to DAM guidelines. Methods: A systematic review of English language articles was undertaken to identify published model-based economic evaluations that examined interventions aimed at lowering BP. The review covered the period January 2000 to March 2015 and included the following electronic bibliographic databases: EMBASE and Medline via Ovid interface and the Centre for Reviews and Dissemination’s (CRD NHS-EED. Data were extracted based on different components of good practice across five dimensions utilizing a framework to assess compliance to DAM guidelines. Results: Thirteen articles were included in this review. The review found limited compliance to good practice DAM guidelines, which was most frequently justified by the lack of data. Conclusions: The assessment of structural uncertainty cannot yet be considered common practice in primary prevention and management of hypertension, and researchers seem to face difficulties with identifying sources of structural uncertainty and then handling them correctly. Additional guidelines are needed to aid researchers in identifying and managing sources of potential structural uncertainty. Adherence to guidelines is not always possible and it does pose challenges, in particular when there are limitations due to data availability that restrict, for example, a validation process.

    heterogeneity remained. This was at least in part due to different inclusion criteria, self-monitoring regimes, and target BPs in included studies. Self-monitoring alone is not associated with lower BP or better control, but in conjunction with co-interventions (including systematic medication titration by doctors, pharmacists, or patients; education; or lifestyle counselling) leads to clinically significant BP reduction which persists for at least 12 months. The implementation of self-monitoring in hypertension should be accompanied by such co-interventions.

    To provide a comprehensive overview of all reported cardiac magnetic resonance (CMR) findings that predict clinical deterioration in pulmonary arterial hypertension (PAH). MEDLINE and EMBASE electronic databases were systematically searched for longitudinal studies published by April 2015 that reported associations between CMR findings and adverse clinical outcome in PAH. Studies were appraised using previously developed criteria for prognostic studies. Meta-analysis using random effect models was performed for CMR findings investigated by three or more studies. Eight papers (539 patients) investigating 21 different CMR findings were included. Meta-analysis showed that right ventricular (RV) ejection fraction was the strongest predictor of mortality in PAH (pooled HR 1.23 [95 % CI 1.07-1.41], p = 0.003) per 5 % decrease. In addition, RV end-diastolic volume index (pooled HR 1.06 [95 % CI 1.00-1.12], p = 0.049), RV end-systolic volume index (pooled HR 1.05 [95 % CI 1.01-1.09], p = 0.013) and left ventricular end-diastolic volume index (pooled HR 1.16 [95 % CI 1.00-1.34], p = 0.045) were of prognostic importance. RV and LV mass did not provide prognostic information (p = 0.852 and p = 0.983, respectively). This meta-analysis substantiates the clinical yield of specific CMR findings in the prognostication of PAH patients. Decreased RV ejection is the strongest and most well established predictor of mortality. (orig.)

    Studies have presented conflicting results regarding the accuracy of ultrasonography (US) for diagnosing portal hypertension (PH). We sought to identify evidence in the literature regarding the accuracy of US for assessing PH in patients with liver cirrhosis. We conducted a systematic review by searching databases, including MEDLINE, EMBASE, and the Cochrane Library, for relevant studies. A total of 14 studies met our inclusion criteria. The US indices were obtained in the portal vein (n = 9), hepatic artery (n = 6), hepatic vein (HV) (n = 4) and other vessels. Using hepatic venous pressure gradient (HVPG) as the reference, the sensitivity (Se) and specificity (Sp) of the portal venous indices were 69-88% and 67-75%, respectively. The correlation coefficients between HVPG and the portal venous indices were approximately 0.296-0.8. No studies assess the Se and Sp of the hepatic arterial indices. The correlation between HVPG and the hepatic arterial indices ranged from 0.01 to 0.83. The Se and Sp of the hepatic venous indices were 75.9-77.8% and 81.8-100%, respectively. In particular, the Se and Sp of HV arrival time for clinically significant PH were 92.7% and 86.7%, respectively. A statistically significant correlation between HVPG and the hepatic venous indices was observed (0.545-0.649). Some US indices, such as HV, exhibited an increased accuracy for diagnosing PH. These indices may be useful in clinical practice for the detection of significant PH.

    While recent state and federal education policies convey a sense of urgency in regard to the need for education reforms, there are teachers for whom this sense of urgency has long been woven into the fabric of their practice. Fortified by their high expectations for their students, these teachers utilize strategies that convey the message that the…

    Deciding between multiple courses of action often entails an increasing need to do something as time passes - a sense of urgency. This notion of urgency is not incorporated in standard theories of speeded decision making that assume information is accumulated until a critical fixed threshold is reached. Yet, it is hypothesized in novel theoretical models of decision making. In two experiments, we investigated the behavioral and neural evidence for an "urgency signal" in human perceptual decision making. Experiment 1 found that as the duration of the decision making process increased, participants made a choice based on less evidence for the selected option. Experiment 2 replicated this finding, and additionally found that variability in this effect across participants covaried with activation in the striatum. We conclude that individual differences in susceptibility to urgency are reflected by striatal activation. By dynamically updating a response threshold, the striatum is involved in signaling urgency in humans. Copyright © 2016 Elsevier Inc. All rights reserved.

  12. Bladder pain syndrome/interstitial cystitis: a sense of urgency.

    Hanno, Philip M; Chapple, Chris R; Cardozo, Linda D

    2009-12-01

    A classic triad of symptoms (bladder pain, urinary frequency, and urgency) has served to define bladder pain syndrome/painful bladder syndrome/interstitial cystitis (BPS/PBS/IC) syndrome. BPS/PBS/IC is a distinct condition and it is likely that the urgency experienced by these patients differs from that experienced by those with overactive bladder syndrome. It is unclear how best to define urgency in the BPS/PBS/IC setting. Differences in the other primary symptoms associated with these conditions probably influence how urgency is perceived. Advances in research into the pathophysiology of urgency and underlying disease processes will help to optimize both the diagnosis and treatment of BPS/PBS/IC.

    Pulmonary arterial hypertension (PAH) is a rare disease (15 cases per million) that is characterized by widespread loss of the pulmonary microcirculation and elevated pulmonary vascular resistance leading to pathological right ventricular remodeling and ultimately right heart failure. Regenerative cell therapies (i.e., therapies involving cells with stem or progenitor-like properties) could potentially restore the effective lung microcirculation and provide a curative therapy for PAH. Preclinical evidence suggests that regenerative cell therapy using endothelial progenitor cells or mesenchymal stem cells may be beneficial in the treatment of PAH. These findings have led to the completion of a small number of human clinical trials, albeit with modest effect compared to animal studies. The objective of this systematic review is to compare the efficacy and safety of regenerative cell therapies in preclinical models of PAH as well as assess study quality to inform future clinical studies. We will include preclinical studies of PAH in which a regenerative cell type was administered and outcomes compared to a disease control. The primary outcome will be pulmonary hemodynamics as assessed by measurement of right ventricular systolic pressure and/or mean pulmonary arterial pressure. Secondary outcomes will include mortality, survival, right ventricular remodeling, pulmonary vascular resistance, cardiac output, cardiac index, pulmonary acceleration time, tricuspid annular systolic excursion, and right ventricular wall thickness. Electronic searches of MEDLINE and EMBASE databases will be constructed and reviewed by the Peer Review of Electronic Search Strategies (PRESS) process. Search results will be screened independently in duplicate. Data from eligible studies will be extracted, pooled, and analyzed using random effects models. Risk of bias will be assessed using the SYstematic Review Centre for Laboratory animal Experimentation (SYRCLE) risk of bias tool, and

  14. Emergency Management of Hypertension in Children

    2012-01-01

    Full Text Available Systemic arterial hypertension in children has traditionally been thought to be secondary in origin. Increased incidence of risk factors like obesity, sedentary life-styles, and faulty dietary habits has led to increased prevalence of the primary arterial hypertension (PAH, particularly in adolescent age children. PAH has become a global epidemic worldwide imposing huge economic constraint on health care. Sudden acute increase in systolic and diastolic blood pressure can lead to hypertensive crisis. While it generally pertains to secondary hypertension, occurrence of hypertensive crisis in PAH is however rare in children. Hypertensive crisis has been further subclassified depending on presence or absence of end-organ damage into hypertensive emergency or urgency. Both hypertensive emergencies and urgencies are known to cause significant morbidity and mortality. Increasing awareness among the physicians, targeted at investigation of the pathophysiology of hypertension and its complications, better screening methods, generation, and implementation of novel treatment modalities will impact overall outcomes. In this paper, we discuss the etiology, pathogenesis, and management of hypertensive crisis in children. An extensive database search using keywords was done to obtain the information.

    To perform a meta-analysis for an assessment of the risk of preeclampsia or gestational hypertension following chorionic villus sampling (CVS). PubMed was systematically searched from its inception through January 2016. Nine reports were identified. A pre-specified scale was used to assess their quality. We performed pooling into three subgroups with respect to the control group: A) Patients with no invasive prenatal diagnostic procedure served as a control group for comparison. The odds ratios for gestational hypertension (0.76, 95% CI 0.46-1.26), preeclampsia (0.83, 95% CI 0.42-1.67), and severe preeclampsia (0.49, 95% CI 0.04-5.78) or when hypertension categories were pooled (0.80, 95% CI 0.46-1.41) were not significantly different. B) Patients with midtrimester diagnostic amniocentesis and patients with no invasive prenatal diagnostic procedure were combined as a control group for comparison. The odds ratios for preeclampsia (1, 95% CI 0.46-2.18), severe preeclampsia (0.83, 95% CI 0.14-4.85), and pooled hypertension categories (1.07, 95% CI 0.63-1.84) were not significantly different. C) Patients with midtrimester diagnostic amniocentesis served as a control group. There was a significant difference in the odds ratio for preeclampsia between the CVS and amniocentesis groups (2.47, 95% CI 1.14-5.33). There was a marginal difference in the odds ratio for combined pregnancy-induced hypertension categories between the CVS and amniocentesis groups (1.61, 95% CI 1.02-2.53). The available data do not indicate an increased risk of preeclampsia or gestational hypertension following first trimester CVS. The heterogeneity and retrospective design of existing studies are limiting factors for our analysis and findings.

    Full Text Available Attorney existence in the Indonesian constitutional structure has a dilemma for this position. On one side is the Prosecutor’s law enforcement agencies to exercise power independently prosecution while on the other hand is part of a government institution under Law No. 16 of 2004 regarding the Attorney. The position of Attorney as an institution of government has been led to the independence of the Prosecutor is not optimal so that it appears stigma that the Prosecutor merely as a tool of the ruling power. In addition the terms of the arrangement just under the Act, the Attorney General has no legal standing as a constitutional organ that has the constitutional authority so that the current position does not reflect the urgency of its duties and functions. In an effort to organize the next Attorney institutions should be regulated directly by the Constitution. It is intended to make the Attorney as part of the main state organs have the same legal standing as other law enforcement agencies, the police and the courts (Supreme Court and Constitutional Court. As well as to strengthen and clarify the position as a state institution, prosecution authorities are focusing on the Attorney as central of authority, to fix the institutional relations between the members of law enforcement and related agencies and strengthen the independence of the Prosecutor in performing the function of prosecution in the constitutional structure of Indonesia.

    A higher cardiovascular morbidity and mortality has been observed in patients with bipolar disorder (BPD) or schizophrenia, partly due to an increased risk of hypertension (HTN), or a less effective care of it. This systematic review and meta-analysis, presents a critical appraisal and summary of the studies addressing the risk of HTN, or the differences in its care, for those with schizophrenia or BPD. Prospective studies were searched in PubMed, Embase, PsycINFO, Scopus, and the Web of Science, from database inception to June 2017. A meta-analysis was undertaken to obtain pooled estimates of the risk of HTN. Five studies reporting the risk of HTN, and five studies presenting differences in its clinical care, were identified. An increased risk of HTN was observed for BPD patients, with an overall Incidence Rate Ratio 1.27(1.15-1.40). The pooled Incidence Rate Ratio of HTN for those with schizophrenia was 0.94 (0.75 - 1.14). A poorer care of HTN (lower rates of screening, prescription, and adherence) was reported in four studies of schizophrenia, and two of BPD patients, compared to people without these conditions. reduced number of studies on risk and care of HTN on patients with BPD or schizophrenia. Limited evidence suggests that patients with BPD have a higher risk of HTN. Patients with schizophrenia and BPD receive poor care of HTN. Understanding the risk of HTN, and the differences in its care, is essential for clinicians to reduce the cardiovascular morbidity and overall mortality of these patients.

    The reported risks of hypertension (HTN) in rotating shift and night shift workers are controversial. The objective of this meta-analysis was to assess the association between shift work status and HTN. A literature search was performed using MEDLINE, EMBASE and Cochrane Database from inception through October 2016. Studies that reported odds ratios (OR) comparing the risk of HTN in shift workers were included. A prespecified subgroup analysis by rotating shift and night shift statuses were also performed. Pooled OR and 95% confidence interval (CI) were calculated using a random-effect, generic inverse variance method. The protocol for this study is registered with International Prospective Register of Systematic Reviews; no. CRD42016051843. Twenty-seven observational studies (nine cohort and 18 cross-sectional studies) with a total of 394 793 individuals were enrolled. The pooled ORs of HTN in shift workers in cohort and cross-sectional studies were 1.31 (95% CI, 1.07-1.60) and 1.10 (95% CI, 1.00-1.20), respectively. When meta-analysis was restricted only to cohort studies in rotating shift, the pooled OR of HTN in rotating shift workers was 1.34 (95% CI, 1.08-1.67). The data regarding night shift and HTN in cohort studies was limited. The pooled OR of HTN in night shift workers in cross-sectional studies was 1.07 (95% CI, 0.85-1.35). Based on the findings of our meta-analysis, shiftwork status may play an important role in HTN, as there is a significant association between rotating shift work and HTN. However, there is no significant association between night shift status and risk of HTN.

    OBJECTIVE The role of venous sinus stenting (VSS) for idiopathic intracranial hypertension (IIH) is not well understood. The aim of this systematic review is to attempt to identify subsets of patients with IIH who will benefit from VSS based on the pressure gradients of their venous sinus stenosis. METHODS MEDLINE/PubMed was searched for studies reporting venous pressure gradients across the stenotic segment of the venous sinus, pre- and post-stent pressure gradients, and clinical outcomes after VSS. Findings are reported according to the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines. RESULTS From 32 eligible studies, a total of 186 patients were included in the analysis. Patients who had favorable outcomes had higher mean pressure gradients (22.8 ± 11.5 mm Hg vs 17.4 ± 8.0 mm Hg, p = 0.033) and higher changes in pressure gradients after stent placement (19.4 ± 10.0 mm Hg vs 12.0 ± 6.0 mm Hg, p = 0.006) compared with those with unfavorable outcomes. The post-stent pressure gradients between the 2 groups were not significantly different (2.8 ± 4.0 mm Hg vs 2.7 ± 2.0 mm Hg, p = 0.934). In a multivariate stepwise logistic regression controlling for age, sex, body mass index, CSF opening pressure, pre-stent pressure gradient, and post-stent pressure gradient, the change in pressure gradient with stent placement was found to be an independent predictor of favorable outcome (p = 0.028). Using a pressure gradient of 21 as a cutoff, 81/86 (94.2%) of patients with a gradient > 21 achieved favorable outcomes, compared with 82/100 (82.0%) of patients with a gradient ≤ 21 (p = 0.022). CONCLUSIONS There appears to be a relationship between the pressure gradient of venous sinus stenosis and the success of VSS in IIH. A randomized controlled trial would help elucidate this relationship and potentially guide patient selection.

    Despite the inverse association between physical activity (PA) and incident hypertension, a comprehensive assessment of the quantitative dose-response association between PA and hypertension has not been reported. We performed a meta-analysis, including dose-response analysis, to quantitatively evaluate this association. We searched PubMed and Embase databases for articles published up to November 1, 2016. Random effects generalized least squares regression models were used to assess the quantitative association between PA and hypertension risk across studies. Restricted cubic splines were used to model the dose-response association. We identified 22 articles (29 studies) investigating the risk of hypertension with leisure-time PA or total PA, including 330 222 individuals and 67 698 incident cases of hypertension. The risk of hypertension was reduced by 6% (relative risk, 0.94; 95% confidence interval, 0.92-0.96) with each 10 metabolic equivalent of task h/wk increment of leisure-time PA. We found no evidence of a nonlinear dose-response association of PA and hypertension ( P nonlinearity =0.094 for leisure-time PA and 0.771 for total PA). With the linear cubic spline model, when compared with inactive individuals, for those who met the guidelines recommended minimum level of moderate PA (10 metabolic equivalent of task h/wk), the risk of hypertension was reduced by 6% (relative risk, 0.94; 95% confidence interval, 0.92-0.97). This meta-analysis suggests that additional benefits for hypertension prevention occur as the amount of PA increases. © 2017 American Heart Association, Inc.

    With the economic development in recent years, there has been a dramatic increase in the prevalence of hypertension in some coastal cities of China; however, the number of reports regarding the prevalence of hypertension based on a nationwide study of island and coastal areas of China is limited. We estimated the prevalence and described the trends of hypertension during the last 3 decades in these specific areas. Authoritative databases were searched for cross-sectional studies reporting the prevalence of hypertension in island and coastal areas of China published in the past 3 decades, and 37 studies that involved 760,428 individuals representing 22 different locations were identified and included in our analysis. The estimated prevalence of hypertension was 9.8% (95% confidence interval (CI) = 6.3%-14.9%) in the 1980s, 18.5% (95% CI = 13.6%-24.8%) in the 1990s, and 30.0% (95% CI = 26.7%-33.6%) in the 2000s (χ(2) for trend: P = 0.00). In the 2000s, adjusted prevalence estimate of hypertension was 21.6% according to the national standard population composition in 1990, and the pooled prevalence estimate for the northern region in coastal areas of China was significantly higher than the southern region (36.2% vs. 26.2%; P = 0.002). Thus, the prevalence of hypertension in the island and coastal areas of China appears to have increased 21.5% in the last 3 decades; the increasing trend was observed in men and women. Our findings highlight the urgent need for public health strategies with more emphasis on improvement of primary health care in the island and coastal areas of China. © American Journal of Hypertension, Ltd 2014.

    We aimed to obtain overall and regional estimates of hypertension prevalence, and to examine the pattern of this disease condition across different socio-demographic characteristics in low-and middle-income countries. We searched electronic databases from inception to August 2015. We included population-based studies that reported hypertension prevalence using the current definition of blood pressure ≥140/90 mm Hg or self-reported use of antihypertensive medication. We used random-effects meta-analyses to pool prevalence estimates of hypertension, overall, by World Bank region and country income group. Meta-regression analyses were performed to explore sources of heterogeneity across the included studies. A total of 242 studies, comprising data on 1,494,609 adults from 45 countries, met our inclusion criteria. The overall prevalence of hypertension was 32.3% (95% confidence interval [CI] 29.4-35.3), with the Latin America and Caribbean region reporting the highest estimates (39.1%, 95% CI 33.1-45.2). Pooled prevalence estimate was also highest across upper middle income countries (37.8%, 95% CI 35.0-40.6) and lowest across low-income countries (23.1%, 95% CI 20.1-26.2). Prevalence estimates were significantly higher in the elderly (≥65 years) compared with younger adults (hypertension prevalence (31.9% vs 30.8%, P = 0.6). Persons without formal education (49.0% vs 24.9%, P hypertensive, compared with those who were educated, normal weight, and rural settlers respectively. This study provides contemporary and up-to-date estimates that reflect the significant burden of hypertension in low- and middle-income countries, as well as evidence that hypertension remains a major public health issue across the various socio-demographic subgroups. On average, about 1 in 3 adults in the developing world is hypertensive. The findings of this study will be useful for the design of hypertension screening and treatment programmes in low- and middle-income countries.

    2013-08-01

    Hypertension affects 10% of pregnancies, many with underlying chronic hypertension, and approximately 1-2% will undergo a hypertensive crisis at some point during their lives. Hypertensive crisis includes hypertensive urgency and emergency; the American College of Obstetricians and Gynecologists describes a hypertensive emergency in pregnancy as persistent (lasting 15 min or more), acute-onset, severe hypertension, defined as systolic BP greater than 160 mmHg or diastolic BP >110 mmHg in the setting of pre-eclampsia or eclampsia. Pregnancy may be complicated by hypertensive crisis, with lower blood pressure threshold for end-organ damage than non-pregnant patients. Maternal assessment should include a thorough history. Fetal assessment should include heart rate tracing, ultrasound for growth and amniotic assessment, and Doppler evaluation if growth restriction is suspected. Initial management of hypertensive emergency (systolic BP >160 mmHg or diastolic BP >110 mmHg in the setting of pre-eclampsia or eclampsia) generally includes the rapid reduction of blood pressure through the use of intravenous antihypertensive medications, with goal systolic blood pressure between 140 mmHg and 150 mmHg and diastolic pressure between 90 mmHg and 100 mmHg. First-line intravenous drugs include labetalol and hydralazine, but other agents may be used, including esmolol, nicardipine, nifedipine, and, as a last resort, sodium nitroprusside. Among patients with hypertensive urgency, slower blood pressure reduction can be provided with oral agents. The objective of this article is to review the current understanding, diagnosis, and management of hypertensive crisis during pregnancy and the postpartum period. Copyright © 2013 Elsevier Inc.

    Blood pressure (BP) control is important to ameliorate cardiovascular events in patients with diabetes mellitus (DM). However, achieving the target BP with a single drug is often difficult. The objective of this study was to evaluate the antihypertensive effects of mineralocorticoid receptor antagonists (MRAs) as add-on therapy to renin-angiotensin system (RAS) inhibitor(s) in patients with hypertension and DM. Studies were searched through October 2014 in MEDLINE, Embase and the Cochrane Central Register of Controlled Trials. Randomized, controlled trials or prospective, observational studies regarding concomitant administration of MRA and RAS inhibitor(s) in patients with DM were included. Articles were excluded if the mean systolic BP (SBP) was hypertension and DM already taking RAS inhibitors. Serum potassium levels should be monitored to prevent hyperkalemia.

    Evening dosing regimen drug therapy on blood pressure (BP) control is used widely, but its clinical benefits and preservation or re-establishment of the normal 24-h BP dipping pattern in chronic kidney disease (CKD) patients is not known. To investigate the effect of an evening dosing regimen of antihypertensive drugs on BP patterns of CKD patients with hypertension. A systematic review was conducted by searching PUBMED, EMBASE, ASN-ONLINE, the Cochrane Library and the reference lists of relevant articles of published papers. All trials designed to evaluate the effects of evening versus morning dosing regimen drug therapy for CKD patients with hypertension were included. Meta-analysis was performed using random or fixed effects models. Five randomised controlled trials and one comparative study, including 3732 patients, met the inclusion criteria. Compared with morning dosing regimen drug therapy, evening administration of antihypertensive medication was associated with a significant reduction of 40% in non-dipper BP patterns (risk ratio (RR), 95% CI, (0.43, 0.84)). We noted a significant decrease in nocturnal systolic blood pressure (SBP) (MD -3.17 mmHg, 95% CI (-5.41, -0.94)), a significant reduction in nocturnal diastolic blood pressure (DBP) (MD -1.37 mmHg, 95% CI (-2.05, -0.69)) and a significant increase in awake SBP (MD 1.15 mmHg, 95% CI (0.10, 2.19)) in patients assigned to the evening dosing regimen drug therapy group. Patients showed no significant differences for all-cause mortality and cardiovascular mortality. This review shows that evening dosing regimen drug therapy could reverse non-dipper BP patterns in hypertensive CKD patients. © 2017 Royal Australasian College of Physicians.

    A systematic review and meta-analysis of randomized controlled trials (RCTs) were performed to understand the effectiveness of medication adherence (MA) interventions among Chinese patients with hypertension. A literature search was conducted with three English databases (PubMed, Web of Science and Embase) and three Chinese databases (China National Knowledge Infrastructure, Wanfang and VIP Database for Chinese Technical Periodicals) for the period from 1970 to October 2017. Only both RCTs with a minimum of 10 participants in each intervention group and Chinese patients with hypertension as participants were included. A random-effects model was applied to calculate pooled effect sizes with 95% CI. Subgroup analysis was conducted to identify potential sources of heterogeneity from duration of intervention, type of intervener, methods of intervention and sites of intervention. Funnel plots and Egger's test were used to evaluate for publication bias. A total of 48 studies met criteria for the meta-analysis, including 14 568 participants, testing 57 independent comparisons. Overall, the effect size revealed that interventions significantly improved MA (pooled relative risk = 1.59, 95% CI: 1.43 to 1.78; pooled Cohen's d = 1.42, 95% CI: 0.976 to 1.876). Interventions were found to significantly reduce blood pressure (BP) (systolic BP: Cohen's d = -0.85, 95% CI: -1.11 to -0.60 and diastolic BP: Cohen's d = -0.73, 95% CI: -1.00 to -0.46). Longer duration of intervention gave better effectiveness. Physician as interventionist, regular follow-up visits and interventions conducted at a hospital were associated with better effectiveness. Adherence interventions improve MA and reduce uncontrolled BP among Chinese patients with hypertension. In the future, investigators should adopt a skill set to address the problem of poor MA. © 2018 Royal Pharmaceutical Society.

    Hypertension is a common disease and a crucial predisposing factor of cardiovascular diseases. Approximately 10% of hypertensive patients are secondary hypertension, a pathogenetic factor of which can be identified. Secondary hypertension consists of endocrine, renal, and other diseases. Primary aldosteronism, Cushing's syndrome, pheochromocytoma, hyperthyroidism, and hypothyroidism result in endocrine hypertension. Renal parenchymal hypertension and renovascular hypertension result in renal hypertension. Other diseases such as obstructive sleep apnea syndrome are also very prevalent in secondary hypertension. It is very crucial to find and treat secondary hypertension at earlier stages since most secondary hypertension is curable or can be dramatically improved by specific treatment. One should keep in mind that screening of secondary hypertension should be done at least once in a daily clinical practice.

    The purpose of this study was to characterize the urinary microbiota in women who are planning treatment for urgency urinary incontinence and to describe clinical associations with urinary symptoms, urinary tract infection, and treatment outcomes. Catheterized urine samples were collected from multisite randomized trial participants who had no clinical evidence of urinary tract infection; 16S ribosomal RNA gene sequencing was used to dichotomize participants as either DNA sequence-positive or sequence-negative. Associations with demographics, urinary symptoms, urinary tract infection risk, and treatment outcomes were determined. In sequence-positive samples, microbiotas were characterized on the basis of their dominant microorganisms. More than one-half (51.1%; 93/182) of the participants' urine samples were sequence-positive. Sequence-positive participants were younger (55.8 vs 61.3 years old; P = .0007), had a higher body mass index (33.7 vs 30.1 kg/m(2); P = .0009), had a higher mean baseline daily urgency urinary incontinence episodes (5.7 vs 4.2 episodes; P urinary incontinence episodes, -4.4 vs -3.3; P = .0013), and were less likely to experience urinary tract infection (9% vs 27%; P = .0011). In sequence-positive samples, 8 major bacterial clusters were identified; 7 clusters were dominated not only by a single genus, most commonly Lactobacillus (45%) or Gardnerella (17%), but also by other taxa (25%). The remaining cluster had no dominant genus (13%). DNA sequencing confirmed urinary bacterial DNA in many women with urgency urinary incontinence who had no signs of infection. Sequence status was associated with baseline urgency urinary incontinence episodes, treatment response, and posttreatment urinary tract infection risk. Copyright © 2015 Elsevier Inc.

    The dominant theoretical paradigm in explaining decision making throughout both neuroscience and cognitive science is known as “evidence accumulation”--The core idea being that decisions are reached by a gradual accumulation of noisy information. Although this notion has been supported by hundreds of experiments over decades of study, a recent theory proposes that the fundamental assumption of evidence accumulation requires revision. The "urgency gating" model assumes decisions are made without accumulating evidence, using only moment-by-moment information. Under this assumption, the successful history of evidence accumulation models is explained by asserting that the two models are mathematically identical in standard experimental procedures. We demonstrate that this proof of equivalence is incorrect, and that the models are not identical, even when both models are augmented with realistic extra assumptions. We also demonstrate that the two models can be perfectly distinguished in realistic simulated experimental designs, and in two real data sets; the evidence accumulation model provided the best account for one data set, and the urgency gating model for the other. A positive outcome is that the opposing modeling approaches can be fruitfully investigated without wholesale change to the standard experimental paradigms. We conclude that future research must establish whether the urgency gating model enjoys the same empirical support in the standard experimental paradigms that evidence accumulation models have gathered over decades of study.

    The prognostic relevance of a hypertensive response to exercise (HRE) is ill-defined in individuals undergoing exercise stress testing. The study described here was intended to provide a systematic review and meta-analysis of published literature to determine the value of exercise-related blood pressure (BP) (independent of office BP) for predicting cardiovascular (CV) events and mortality. Online databases were searched for published longitudinal studies reporting exercise-related BP and CV events and mortality rates. We identified for review 12 longitudinal studies with a total of 46,314 individuals without significant coronary artery disease, with total CV event and mortality rates recorded over a mean follow-up of 15.2±4.0 years. After adjustment for age, office BP, and CV risk factors, an HRE at moderate exercise intensity carried a 36% greater rate of CV events and mortality (95% CI, 1.02-1.83, P = 0.039) than that of subjects without an HRE. Additionally, each 10mm Hg increase in systolic BP during exercise at moderate intensity was accompanied by a 4% increase in CV events and mortality, independent of office BP, age, or CV risk factors (95% CI, 1.01-1.07, P = 0.02). Systolic BP at maximal workload was not significantly associated with the outcome of an increased rate of CV, whether analyzed as a categorical (HR=1.49, 95% CI, 0.90-2.46, P = 0.12) or a continuous (HR=1.01, 95% CI, 0.98-1.04, P = 0.53) variable. An HRE at moderate exercise intensity during exercise stress testing is an independent risk factor for CV events and mortality. This highlights the need to determine underlying pathophysiological mechanisms of exercise-induced hypertension.

    The mighty Himalayas are great repositories of snow and ice. The river system of Indus, the Ganges and Brahmaputra owe their perennial flow to these large snow and ice masses. The demand for systematic exploitation of water resources of these great mountain ranges calls for a thorough inventory of these water-holding bodies. Rough and difficult terrain, inclement weather and very inaccessible altitudes stood in the way for better understanding of these vast sources of life giving water. In this paper, the urgency for snow and glacier mapping of this Himalayan region is highlighted in the light of the fast evolving techniques of remote sensing. Aerospace photography, use of radars and infrared sensing methods microwave sensing, and application of gamma radiation with the help of satellites, are examined for their present status and future potential for application in this ice and snow capped, top of the world.

    Tobacco use significantly increases cardiovascular complications in people living with hypertension and/or diabetes. We aim to summarise data on the prevalence and factors associated with active smoking in these conditions in Africa. We will search PubMed, Embase, Google Scholar and African Journals Online for relevant abstracts of studies on active smoking in individuals living with diabetes and/or hypertension published from 1 January 2000 to 31 December 2016, with no language restriction. Additionally, relevant unpublished papers and conference proceedings will be checked, as well as references of included articles. Two investigators will independently screen, select studies, extract data and assess the risk of bias in each study. Data will be analysed using Stata software (Stata V.14, Texas, USA). The study-specific estimates will be pooled through a random-effects meta-analysis model to obtain an overall summary estimate of the prevalence of smoking across studies. Also, we will assess factors associated to smoking. Heterogeneity of studies will be evaluated by the χ2 test on Cochrane's Q statistic. Funnel plots analysis and Egger's test will be done to detect publication bias. Results will be presented by geographic region (central, eastern, northern, southern and western Africa). A p value less than 0.05 will be considered significant for factors associated to smoking. This study is based on published data, and therefore ethical approval is not a requirement. This systematic review and meta-analysis is expected to serve as a basis for designing cost-effective interventions to reduce and prevent smoking in patients with diabetes and/or hypertension, and as a guide for future research based on the remaining gaps. The final report of this study in the form of a scientific paper will be published in peer-reviewed journals. Findings will further be presented at conferences and submitted to relevant health authorities. © Article author(s) (or their employer

  1. Standards and pitfalls of focal ischemia models in spontaneously hypertensive rats: With a systematic review of recent articles

    2012-07-01

    Full Text Available Abstract We reviewed the early development of various focal ischemia models in spontaneously hypertensive rats (SHR, and summarized recent reports on this topic. Among 6 focal ischemia models established in divergent substrains of SHR, distal middle cerebral artery occlusion is the most frequently used and relevant method of focal ischemia in the light of penumbra concept. We performed an online PubMed search (2001–2010, and identified 118 original articles with focal ischemia in SHR. Physiological parameters such as age, body weight, and even blood pressure were often neglected in the literature: the information regarding the physiological parameters of SHR is critical, and should be provided within the methodology section of all articles related to stroke models in SHR. Although the quality of recent studies on neuroprotective strategy is improving, the mechanisms underlying the protection should be more clearly recognized so as to facilitate the translation from animal studies to human stroke. To overcome the genetic heterogeneity in substrains of SHR, new approaches, such as a huge repository of genetic markers in rat strains and the congenic strategy, are currently in progress.

  2. Effect of hypoxia and hyperoxia on exercise performance in healthy individuals and in patients with pulmonary hypertension: a systematic review.

    Exercise performance is determined by oxygen supply to working muscles and vital organs. In healthy individuals, exercise performance is limited in the hypoxic environment at altitude, when oxygen delivery is diminished due to the reduced alveolar and arterial oxygen partial pressures. In patients with pulmonary hypertension (PH), exercise performance is already reduced near sea level due to impairments of the pulmonary circulation and gas exchange, and, presumably, these limitations are more pronounced at altitude. In studies performed near sea level in healthy subjects, as well as in patients with PH, maximal performance during progressive ramp exercise and endurance of submaximal constant-load exercise were substantially enhanced by breathing oxygen-enriched air. Both in healthy individuals and in PH patients, these improvements were mediated by a better arterial, muscular, and cerebral oxygenation, along with a reduced sympathetic excitation, as suggested by the reduced heart rate and alveolar ventilation at submaximal isoloads, and an improved pulmonary gas exchange efficiency, especially in patients with PH. In summary, in healthy individuals and in patients with PH, alterations in the inspiratory Po 2 by exposure to hypobaric hypoxia or normobaric hyperoxia reduce or enhance exercise performance, respectively, by modifying oxygen delivery to the muscles and the brain, by effects on cardiovascular and respiratory control, and by alterations in pulmonary gas exchange. The understanding of these physiological mechanisms helps in counselling individuals planning altitude or air travel and prescribing oxygen therapy to patients with PH.

  3. Why do hypertensive patients of African ancestry respond better to calcium blockers and diuretics than to ACE inhibitors and β-adrenergic blockers? A systematic review

    Science.gov (United States)

    2013-01-01

    Background Clinicians are encouraged to take an individualized approach when treating hypertension in patients of African ancestry, but little is known about why the individual patient may respond well to calcium blockers and diuretics, but generally has an attenuated response to drugs inhibiting the renin-angiotensin system and to β-adrenergic blockers. Therefore, we systematically reviewed the factors associated with the differential drug response of patients of African ancestry to antihypertensive drug therapy. Methods Using the methodology of the systematic reviews narrative synthesis approach, we sought for published or unpublished studies that could explain the differential clinical efficacy of antihypertensive drugs in patients of African ancestry. PUBMED, EMBASE, LILACS, African Index Medicus and the Food and Drug Administration and European Medicines Agency databases were searched without language restriction from their inception through June 2012. Results We retrieved 3,763 papers, and included 72 reports that mainly considered the 4 major classes of antihypertensive drugs, calcium blockers, diuretics, drugs that interfere with the renin-angiotensin system and β-adrenergic blockers. Pharmacokinetics, plasma renin and genetic polymorphisms did not well predict the response of patients of African ancestry to antihypertensive drugs. An emerging view that low nitric oxide and high creatine kinase may explain individual responses to antihypertensive drugs unites previous observations, but currently clinical data are very limited. Conclusion Available data are inconclusive regarding why patients of African ancestry display the typical response to antihypertensive drugs. In lieu of biochemical or pharmacogenomic parameters, self-defined African ancestry seems the best available predictor of individual responses to antihypertensive drugs. PMID:23721258

    The goal of the study was to determine the blood pressure (BP) response to renal artery stenting (RAS) for patients with hypertension urgency, hypertension emergency, and angina with congestive heart failure (angina/congestive heart failure [CHF]). Patients who underwent RAS for hypertension emergencies (n = 13), hypertension urgencies (n = 25), and angina/CHF (n = 14) were included in the analysis. By convention, hypertension urgency was defined by a sustained systolic BP ≥ 180 mm Hg or diastolic BP ≥ 120 mm Hg, while the definition of hypertension emergency required the same BP parameters plus hypertension-related symptoms prompting hospitalization. Patient-specific response to RAS was defined according to modified American Heart Association reporting guidelines. The study cohort of 52 patients had a median age of 66 years (interquartile range 58-72). The BP response to RAS varied significantly according to the indication for RAS. Hypertension emergency provided the highest BP response rate (85%), while the response rate was significantly lower for hypertension urgency (52%) and angina/CHF (7%; P = .03). Only 1 of 14 patients with angina/CHF was a BP responder. Multivariate analysis showed that hypertension urgency or emergency were not independent predictors of BP response to RAS. Instead, the only independent predictor of a favorable BP response was the number of preoperative antihypertensive medications (odds ratio 7.5; 95% confidence interval 2.5-22.9; P = .0004), which is another indicator of the severity of hypertension. Angina/CHF was an independent predictor of failure to respond to RAS (odds ratio 118.6; 95% confidence interval 2.8-999.9; P = .013). Hypertension urgency and emergency are clinical manifestations of severe hypertension, but the number of preoperative antihypertensive medications proved to be a better predictor of a favorable BP response to RAS. In contrast, angina/CHF was a predictor of failure to respond to stenting, providing further

    Pulmonary hypertension (PH) complicating chronic obstructive pulmonary disease (COPD-PH) and interstitial lung disease (ILD-PH) (World Health Organization [WHO] Group III PH) increases medical costs and reduces survival. Despite limited data, many clinicians are using pulmonary arterial hypertension (PAH)-specific therapy to treat WHO Group III PH patients. To further investigate the utility of PAH-specific therapy in WHO Group III PH, we performed a systematic review and meta-analysis. Relevant studies from January 2000 through May 2016 were identified in the MEDLINE, EMBASE, and COCHRANE electronic databases and www.clinicaltrials.gov. Change in six-minute walk distance (6MWD) was estimated using random effects meta-analysis techniques. Five randomized controlled trials (RCTs) in COPD-PH (128 placebo or standard treatment and 129 PAH-medication treated patients), two RCTs in ILD-PH (23 placebo and 46 treated patients), and four single-arm clinical trials (50 patients) in ILD-PH were identified. Treatment in both COPD-PH and ILD-PH did not worsen hypoxemia. Symptomatic burden was not consistently reduced but there were trends for reduced pulmonary artery pressures and pulmonary vascular resistance with PAH-specific therapy. As compared to placebo, 6MWD was not significantly improved with PAH-specific therapy in the five COPD-PH RCTs (42.7 m; 95% confidence interval [CI], -1.0 - 86.3). In the four single-arm studies in ILD-PH patients, there was a significant improvement in 6MWD after PAH-specific treatment (46.2 m; 95% CI, 27.9-64.4), but in the two ILD-PH RCTs there was not an improvement (21.6 m; 95% CI, -17.8 - 61.0) in exercise capacity when compared to placebo. Due to the small numbers of patients evaluated and inconsistent beneficial effects, the utility of PAH-specific therapy in WHO Group III PH remains unproven. A future clinical trial that is appropriately powered is needed to definitively determine the efficacy of this widely implemented treatment

    2003-03-01

    To examine the perceived urgency of 13 auditory warning alarms commonly occurring in the hospital operating room. Undergraduate students, who were naïve with respect to the clinical situation associated with the alarms, judged perceived urgency of each alarm on a ten-point scale. The perceived urgency of the alarms was not consistent with the actual urgency of the clinical situation that triggers it. In addition, those alarms indicating patient condition were generally perceived as less urgent than those alarms indicating the operation of equipment. Of particular interest were three sets of alarms designed by equipment manufacturers to indicate specific priorities for action. Listeners did not perceive any differences in the urgency of the 'information only', 'medium' and 'high' priority alarms of two of the monitors with all judged as low to moderate in urgency. In contrast, the high priority alarm of the third monitor was judged as significantly more urgent than its low and medium urgency counterparts. The alarms currently in use do not convey the intended sense of urgency to naïve listeners, and this holds even for two sets of alarms designed specifically by manufacturers to convey different levels of urgency.

    Hibiscus sabdariffa L. is a tropical wild plant rich in organic acids, polyphenols, anthocyanins, polysaccharides, and volatile constituents that are beneficial for the cardiovascular system. Hibiscus sabdariffa beverages are commonly consumed to treat arterial hypertension, yet the evidence from randomized controlled trials (RCTs) has not been fully conclusive. Therefore, we aimed to assess the potential antihypertensive effects of H. sabdariffa through systematic review of literature and meta-analysis of available RCTs. The search included PUBMED, Cochrane Library, Scopus, and EMBASE (up to July 2014) to identify RCTs investigating the efficacy of H. sabdariffa supplementation on SBP and DBP values. Two independent reviewers extracted data on the study characteristics, methods, and outcomes. Quantitative data synthesis and meta-regression were performed using a fixed-effect model, and sensitivity analysis using leave-one-out method. Five RCTs (comprising seven treatment arms) were selected for the meta-analysis. In total, 390 participants were randomized, of whom 225 were allocated to the H. sabdariffa supplementation group and 165 to the control group in the selected studies. Fixed-effect meta-regression indicated a significant effect of H. sabdariffa supplementation in lowering both SBP (weighed mean difference -7.58 mmHg, 95% confidence interval -9.69 to -5.46, P < 0.00001) and DBP (weighed mean difference -3.53 mmHg, 95% confidence interval -5.16 to -1.89, P < 0.0001). These effects were inversely associated with baseline BP values, and were robust in sensitivity analyses. This meta-analysis of RCTs showed a significant effect of H. sabdariffa in lowering both SBP and DBP. Further well designed trials are necessary to validate these results.

    Previous studies report benefits of exercise for blood pressure control in middle age and older adults, but longer-term effectiveness in younger adults is not well established. We performed a systematic review and meta-analysis of published randomized control trials with meta-regression of potential effect modifiers. An information specialist completed a comprehensive search of available data sources, including studies published up to June 2015. Authors applied strict inclusion and exclusion criteria to screen 9524 titles. Eligible studies recruited younger adults with a cardiovascular risk factor (with at least 25% of cohort aged 18-40 years); the intervention had a defined physical activity strategy and reported blood pressure as primary or secondary outcome. Meta-analysis included 14 studies randomizing 3614 participants, mean age 42.2±6.3 (SD) years. At 3 to 6 months, exercise was associated with a reduction in systolic blood pressure of -4.40 mm Hg (95% confidence interval, -5.78 to -3.01) and in diastolic blood pressure of -4.17 mm Hg (95% confidence interval, -5.42 to -2.93). Intervention effect was not significantly influenced by baseline blood pressure, body weight, or subsequent weight loss. Observed intervention effect was lost after 12 months of follow-up with no reported benefit over control, mean difference in systolic blood pressure -1.02 mm Hg (95% confidence interval, -2.34 to 0.29), and in diastolic blood pressure -0.91 mm Hg (95% confidence interval, -1.85 to 0.02). Current exercise guidance provided to reduce blood pressure in younger adults is unlikely to benefit long-term cardiovascular risk. There is need for continued research to improve age-specific strategies and recommendations for hypertension prevention and management in young adults. © 2016 The Authors.

    Resistant hypertension is a severe medical condition which is estimated to appear in 9-18% of hypertensive patients. Due to higher cardiovascular risk, this disorder requires special diagnosis and treatment. The heterogeneous etiology, risk factors and comorbidities of resistant hypertension stand in need of sophisticated evaluation to confirm the diagnosis and select the best therapeutic options, which should consider lifestyle modifications as well as pharmacological and interventional treatment. After having excluded pseudohypertension, inappropriate blood pressure measurement and control as well as the white coat effect, suspicion of resistant hypertension requires an analysis of drugs which the hypertensive patient is treated with. According to one definition - ineffective treatment with 3 or more antihypertensive drugs including diuretics makes it possible to diagnose resistant hypertension. A multidrug therapy including angiotensin - converting enzyme inhibitors, angiotensin II receptor blockers, beta blockers, diuretics, long-acting calcium channel blockers and mineralocorticoid receptor antagonists has been demonstrated to be effective in resistant hypertension treatment. Nevertheless, optional, innovative therapies, e.g. a renal denervation or baroreflex activation, may create a novel pathway of blood pressure lowering procedures. The right diagnosis of this disease needs to eliminate the secondary causes of resistant hypertension e.g. obstructive sleep apnea, atherosclerosis and renal or hormonal disorders. This paper briefly summarizes the identification of the causes of resistant hypertension and therapeutic strategies, which may contribute to the proper diagnosis and an improvement of the long term management of resistant hypertension.

    Urgency for prompt and coordinated action by industrialized countries is emphasized in this analysis of the earth's most pressing environmental problems - desertification, acid rain, deforestation, the greenhouse effect and ozone depletion. In the analysis of the chemical, physical, thermochemical and climatic processes (e.g., ozone reactions with chlorofluorocarbons, Antarctic atmospheric vortex circulation, volcanic eruptions, the earth's water and carbon cycles, cyclic global temperature variations, etc.) governing the formation and modification of the various environmentally destabilizing phenomena, and in the assessments of the severity and duration of the effects, the paper evidences global and socio-economic aspects relative to the probable causes and proposed solutions. The author states that whereas greater investment by industrialized countries in environmental protection and technology transfer programs is essential to save the earth's natural resources, overall positive results can be achieved only through a contemporaneous change in social values to favour the sharing of the earth's wealth among nations and future generations

    Full Text Available Deborah R Stein, Michael A Ferguson Division of Nephrology, Boston Children's Hospital, Harvard Medical School, Boston, MA, USA Abstract: Hypertensive crises in children are medical emergencies that must be identified, evaluated, and treated promptly and appropriately to prevent end-organ injury and even death. Treatment in the acute setting typically includes continuous intravenous antihypertensive medications with monitoring in the intensive care unit setting. Medications commonly used to treat severe hypertension have been poorly studied in children. Dosing guidelines are available, although few pediatric-specific trials have been conducted to facilitate evidence-based therapy. Regardless of what medication is used, blood pressure should be lowered gradually to allow for accommodation of autoregulatory mechanisms and to prevent cerebral ischemia. Determining the underlying cause of the blood pressure elevation may be helpful in guiding therapy.

    Full Text Available Hypertension affects about 10 - 25% of the population and is an important risk factor for cardiovascular and renal disease. The renin-angiotensin system is frequently implicated in the pathophysiology of hypertension, be it primary or secondary. The prevalence of primary aldosteronism increases with the severity of hypertension, from 2% in patients with grade 1 hypertension to 20% among resistant hypertensives. Mineralcorticoid hypertension includes a spectrum of disorders ranging from renin-producing pathologies (renin-secreting tumors, malignant hypertension, coarctation of aorta, aldosterone-producing pathologies (primary aldosteronism - Conns syndrome, familial hyperaldosteronism 1, 2, and 3, non-aldosterone mineralocorticoid producing pathologies (apparent mineralocorticoid excess syndrome, Liddle syndrome, deoxycorticosterone-secreting tumors, ectopic adrenocorticotropic hormones (ACTH syndrome, congenitalvadrenal hyperplasia, and drugs with mineraocorticoid activity (locorice, carbenoxole therapy to glucocorticoid receptor resistance syndromes. Clinical presentation includes hypertension with varying severity, hypokalemia, and alkalosis. Ratio of plasma aldosterone concentraion to plasma renin activity remains the best screening tool. Bilateral adrenal venous sampling is the best diagnostic test coupled with a CT scan. Treatment is either surgical (adrenelectomy for unilateral adrenal disease versus medical therapy for idiopathic, ambiguous, or bilateral disease. Medical therapy focuses on blood pressure control and correction of hypokalemia using a combination of anti-hypertensives (calcium channel blockers, angiotensin converting enzyme inhibitors, or angiotensin receptor blockers and potassium-raising therapies (mineralcorticoid receptor antagonist or potassium sparing diuretics. Direct aldosterone synthetase antagonists represent a promising future therapy.

    One significant concern that pilots have about cockpit auditory warnings is that the signals presently used lack a sense of priority. The relationship between auditory warning sound parameters and perceived urgency is, therefore, an important topic of enquiry in aviation psychology. The present investigation examined the relationship among subjective assessments of urgency, reaction time, and brainwave activity with three auditory warning signals. Subjects performed a tracking task involving automated and manual conditions, and were presented with auditory warnings having various levels of perceived and situational urgency. Subjective assessments revealed that subjects were able to rank warnings on an urgency scale, but rankings were altered after warnings were mapped to a situational urgency scale. Reaction times differed between automated and manual tracking task conditions, and physiological data showed attentional differences in response to perceived and situational warning urgency levels. This study shows that the use of physiological measures sensitive to attention and arousal, in conjunction with behavioural and subjective measures, may lead to the design of auditory warnings that produce a sense of urgency in an operator that matches the urgency of the situation.

  17. Integrating affect and impulsivity: The role of positive and negative urgency in substance use risk.

    The personality traits of positive and negative urgency refer to the tendencies to act rashly when experiencing unusually positive or negative emotions, respectively. The authors review recent empirical work testing urgency theory (Cyders and Smith, 2008a) and consider advances in theory related to these traits. Empirical findings indicate that (a) the urgency traits are particularly important predictors of the onset of, and increases in, substance use in both children and young adults; (b) they appear to operate in part by biasing psychosocial learning; (c) pubertal onset is associated with increases in negative urgency, which in turn predict increases in adolescent drinking behavior; (d) variation in negative urgency trait levels are associated with variations in the functioning of an identified brain system; and (e) variations in the serotonin transporter gene, known to influence the relevant brain system, relate to variations in the urgency traits. A recent model (Carver et al., 2008) proposes the urgency traits to be markers of a tendency to respond reflexively to emotion, whether through impulsive action or ill-advised inaction (the latter leading to depressive symptoms); this model has received empirical support. The authors discuss new directions for research on the urgency traits. Copyright © 2016 The Authors. Published by Elsevier Ireland Ltd.. All rights reserved.

    Young adults with higher trait urgency (i.e., a tendency to act rashly in response to heightened affect) may be especially vulnerable to heavy drinking. The current study examined 1) the influence of urgency on daily relations between affect and drinking to intoxication, and 2) whether urgency influenced the effectiveness of naltrexone (vs. placebo) for reducing alcohol use. This study is a secondary analysis of data from 126 (n=40 female) heavy drinking young adults, ages 18-25, enrolled in a double-blind, 8-week clinical trial comparing brief motivational intervention and either naltrexone or placebo. Multilevel models examined whether trait urgency moderated daily relations between positive and negative affect and drinking to intoxication, measured by an estimated blood-alcohol concentration (eBAC) at or above the legal limit (≥0.08g%). Person-level interactions examined whether naltrexone was more effective than placebo at reducing the odds of eBAC≥0.08g% for individuals with higher vs. lower trait urgency. On days of greater within-person positive or negative affect, young adults with higher urgency were more likely to drink to intoxication than those with lower urgency. Naltrexone reduced the odds of drinking to intoxication significantly more than placebo, independent of positive or negative urgency. Although naltrexone treatment reduced drinking overall, young adults with higher trait urgency were still at increased risk for hazardous drinking following times of strong positive or negative mood. Targeted interventions are needed to reduce the risk of heavy drinking among young adults with high trait urgency. Copyright © 2016 Elsevier Ireland Ltd. All rights reserved.

    β-Blockers are less effective than other antihypertensive drug classes in reducing central systolic blood pressure (cSBP) as compared with peripheral SBP (pSBP). Whether this effect is less pronounced with vasodilating β-blockers (VBB) when compared with nonvasodilating β-blockers (NVBB) remains unsettled. We conducted a systematic review and meta-analysis of randomized trials exploring the effects of β-blockers on both pSBP and cSBP in hypertension. We selected 20 studies, for a total of 32 treatment arms (n=21 for NVBB, n=11 for VBB) and 1263 participants (n=962 for NVBB, n=301 for VBB). pSBP decreased from 150 to 133 mm Hg for NVBB and from 145 to 134 mm Hg for VBB. cSBP decreased from 137 to 126 mm Hg for NVBB and from 132 to 123 mm Hg for VBB. SBP amplification (pSBP-cSBP) decreased significantly under VBB (-5.6 mm Hg; 95% confidence interval, -7.8, -3.4 mm Hg), but not under NVBB (-1.1 mm Hg; 95% confidence interval, -3.4, +1.2 mm Hg; P<0.01 versus NVBB). There was high heterogeneity both within and between β-blockers subclasses. In a meta-regression model, the weighted difference in treatment-induced changes in SBP amplification between NVBB and VBB lost its significance after adjustment for mean age and baseline pSBP and heart rate (-2.9±2.3 mm Hg; P=0.22) and was almost abolished after adjustment for treatment-induced heart rate changes (-0.1±0.5 mm Hg; P=0.78). In conclusion, NVBBs, but not VBBs, determine a lower reduction in cSBP than in pSBP. However, the difference in treatment-induced SBP amplification changes between NVBB and VBB is nearly abolished after accounting for differences in heart rate changes. © 2015 American Heart Association, Inc.

    For nearly 50 years, the dominant account of decision-making holds that noisy information is accumulated until a fixed threshold is crossed. This account has been tested extensively against behavioral and neurophysiological data for decisions about consumer goods, perceptual stimuli, eyewitness testimony, memories, and dozens of other paradigms, with no systematic misfit between model and data. Recently, the standard model has been challenged by alternative accounts that assume that less evidence is required to trigger a decision as time passes. Such "collapsing boundaries" or "urgency signals" have gained popularity in some theoretical accounts of neurophysiology. Nevertheless, evidence in favor of these models is mixed, with support coming from only a narrow range of decision paradigms compared with a long history of support from dozens of paradigms for the standard theory. We conducted the first large-scale analysis of data from humans and nonhuman primates across three distinct paradigms using powerful model-selection methods to compare evidence for fixed versus collapsing bounds. Overall, we identified evidence in favor of the standard model with fixed decision boundaries. We further found that evidence for static or dynamic response boundaries may depend on specific paradigms or procedures, such as the extent of task practice. We conclude that the difficulty of selecting between collapsing and fixed bounds models has received insufficient attention in previous research, calling into question some previous results.

    Errors in drug administration are the second cause of errors in hospitalized patients. Children are a high risk group. Besides, pressure in care interventions at emergency department leads to increase incidence errors. Determining nurses' knowledge about the most common drug doses at pediatric urgency department. Descriptive transversal study. We collected data from nurses of 14 pediatric emergency departments of Madrid. With an "ad hoc" questionnaire we collected the following data during five days in January of 2014: demographic, knowledge of responsibility in administration and doses of drugs. Global descriptive analysis was made and it was stratified by hospital and work experience. The answer rate was 114 (34.9%). Only 80 (70.8%) of nurses confirm doses before their administration; 20 (18.6%) think that a wrong prescription that they administer is not their responsibility. There is a high knowledge in the group with more than five years of work experience, except for sedative-analgesic drugs (p<0.05). The average score obtained was 3.8 of 10 (1.99). Nurses' knowledge about drug doses is low. Copyright © 2016 Elsevier España, S.L.U. All rights reserved.

  3. Negative and positive urgency may both be risk factors for compulsive buying.

    2014-06-01

    Descriptions of compulsive buying often emphasize the roles of negative moods and trait impulsivity in the development of problematic buying habits. Trait impulsivity is sometimes treated as a unidimensional trait in compulsive buying research, but recent factor analyses suggest that impulsivity consists of multiple components that are probably best treated as independent predictors of problem behavior. In order to draw greater attention to the role of positive moods in compulsive buying, in this study we tested whether negative urgency (the tendency to act rashly while in negative moods) and positive urgency (the tendency to act rashly while in positive moods) account for similar amounts of variance in compulsive buying. North American adults (N = 514) completed an online survey containing the Richmond Compulsive Buying Scale (Ridgway, Kukar-Kinney & Monroe, 2008), established measures of positive and negative urgency (Cyders et al., 2007), ad hoc measures of buying-specific positive and negative urgency, measures of extraversion and neuroticism obtained from the International Personality Item Pool (http://ipip.ori.org/), and demographic questions. In several multiple regression analyses, when demographic variables, neuroticism, and extraversion were controlled, positive urgency and negative urgency both emerged as significant predictors of compulsive buying. Whether the two urgency variables were domain-general or buying-specific, they accounted for similar amounts of variance in compulsive buying. Preventing and reducing compulsive buying may require attention not only to the purchasing decisions people make while in negative states, but also to the purchasing decisions they make while in positive states.

    The objective was to estimate the impact of stress and urgency urinary incontinence (UI) on the quality of life (QOL), and to determine whether the impact varies according to UI severity. We used data from the General Longitudinal Overactive Bladder Evaluation-UI study in women. Stress and urgency UI symptom severity scores ranged from 0 to 8. We used logistic regression to test the relation among different severity levels of stress and urgency UI, and their interaction with the Incontinence Impact Questionnaire (IIQ-7). This was categorized according to percentage ranges as 0-40% (reference), 41-80%, and 81-100%. Both stress and urgency UI were significantly associated with IIQ-7. Higher scores had higher odds ratios (ORs). The OR for urgency vs stress UI was greater at the same severity level. For instance, comparing IIQ-7 quintiles (0-40% vs 41-80%), the OR for an association with an urgency UI score of 5-6 was 5.27 (95% CI = 3.78-7.33) vs 2.76 (95% CI = 2.07-3.68) for a stress UI score of 5-6. Both UI subtypes were more strongly related to the upper (81-100%) than the to the lower (41-80%) quintiles. There was a strong positive urgency UI and stress UI interaction with the upper (i.e., 81-100%) but not the two next lower (41-80%) quintiles. The impact of UI subtypes on QOL varies according to the score of IIQ-7, stress and urgency UI, and their interaction. Urgency vs stress UI has a stronger impact. The effect is greatest for high IIQ-7 scores with a significant share mediated by the interaction of the two UI subtypes.

    The publication of the first non-randomised proof-of-concept trial of renal denervation as a treatment modality in treatment-resistant hypertension set the stage for a search for novel devices with the expectation that technology would reduce the burden of hypertension by reducing or eliminating the costly and lifelong use of blood pressure lowering medications. As we demonstrate in this review, this idea so attractive to manufacturers and invasive cardiologists and radiologists overlooked decades of careful pathophysiological research in a disease, which still remains enigmatic but remains the major cause of cardiovascular mortality worldwide. To make our point, we first reviewed the prevalence and risks associated with treatment-resistant hypertension. Next, we highlighted the key points required for the diagnosis of treatment-resistant hypertension, including the recording of the ambulatory blood pressure and the assessment of adherence to medication. Finally, we summarised new insights in the management of treatment-resistant hypertension by medication and devices and in the future research. Throughout our review, we focused on new evidence became available since 2013. Our conclusion is that optimising medical treatment based on simple algorithms remains the state of the art in treatment-resistant hypertension.

    When designed correctly, non-verbal auditory alarms can convey different levels of urgency to the aircrew, and thereby permit the operator to establish the appropriate level of priority to address the alarmed condition. The conveyed level of urgency of five non-verbal auditory alarms presently used in the Canadian Forces CH-146 Griffon helicopter was investigated. Pilots of the CH-146 Griffon helicopter and non-pilots rated the perceived urgency of the signals using a rating scale. The pilots also ranked the urgency of the alarms in a post-experiment questionnaire to reflect their assessment of the actual situation that triggers the alarms. The results of this investigation revealed that participants' ratings of perceived urgency appear to be based on the acoustic properties of the alarms which are known to affect the listener's perceived level of urgency. Although for 28% of the pilots the mapping of perceived urgency to the urgency of their perception of the triggering situation was statistically significant for three of the five alarms, the overall data suggest that the triggering situations are not adequately conveyed by the acoustic parameters inherent in the alarms. The pilots' judgement of the triggering situation was intended as a means of evaluating the reliability of the alerting system. These data will subsequently be discussed with respect to proposed enhancements in alerting systems as it relates to addressing the problem of phase of flight. These results call for more serious consideration of incorporating situational awareness in the design and assignment of auditory alarms in aircraft.

Urgency influenced decision times and evoked heart rate responses, interacting with the expected value of each gamble. Usin...

    Among early adolescents in the United States (U.S.), the prevalence of cigarette smoking is at its lowest level in recent decades. Nonetheless, given the risks of smoking in early development, it remains critically important to study both risk factors for smoking and risks from smoking. This longitudinal study with U.S. early adolescents examines smoking initiation and tests a model of reciprocal prediction between ever smoking and the personality trait of urgency (i.e., mood-based impulsivity), a trait that increases risk for multiple forms of dysfunction. Participants (n=1906; 90% 10-11 years old, 50% female, 39% racial minorities at baseline) completed questionnaires 1-2 times per year starting in 5th grade and ending in 9th grade. Structural equation modeling allowed tests of bidirectional relationships between ever smoking and urgency controlling for pubertal status and negative affect at each wave. Incidence of ever smoking increased from 5% to 27% over time, with current smoking around 5% at the last wave. Urgency at each wave predicted ever smoking at the next wave above and beyond covariates and prior smoking (all psmoking predicted an increase in urgency at the subsequent wave above and beyond covariates and prior urgency (all psmoking increases with higher levels of urgency and urgency increases secondary to engagement in smoking. Future work should therefore explore urgency as a point of prevention for smoking and smoking cessation as a means to mitigate mood-based impulsivity. Copyright © 2017 Elsevier B.V.

    The urgency facet of impulsivity, that is, the tendency to act rashly in response to intense emotional contexts [Cyders, M. A., & Smith, G. T. (2008). Emotion-based dispositions to rash action: positive and negative urgency. Psychological Bulletin, 134, 807-828], has been related to a wide range of maladaptive behaviours. The present study further investigates the role of urgency in problematic behaviours by considering distinct psychological mechanisms that may underlie this component of impulsivity. With this aim, 95 volunteer participants were screened with self-reported questionnaires assessing urgency and three problematic behaviours (compulsive buying, excessive mobile phone use, excessive Internet use). They performed two laboratory tasks: a stop-signal task designed to assess the capacity to inhibit prepotent responses in response to both neutral and emotional stimuli; and the Iowa Gambling Task (IGT) measuring the ability to take into account the future consequences of an action. A poor ability to inhibit prepotent responses in the emotional condition of the stop-signal task was found to predict more disadvantageous choices in the IGT, which ultimately results in higher urgency and more problematic behaviours. These findings shed new light on the construct of urgency, its related psychological mechanisms, and its role in problematic behaviours. Copyright © 2010 Elsevier Ltd. All rights reserved.

    Hypertension constitutes a major health problem and the challenge is to identify patients having 'surgically' curable renal vascular disease among the majority with so-called essential hypertension. The best of unsatisfactory diagnostic tests are renography and plasma renin activity both before and during angiotensin II blockade. The necessity of better screening tests has increased because of the recent advances in surgical techniques and especially percutaneous transluminal renal angioplasty. The latter has definitely become the method of choice for correction of suspected hemodynamically significant artery stenoses whenever technically feasible. With improved angioplasty techniques the risk of treating renal artery stenosis without hemodynamic and clinical importance (so-called cosmetic repair) has increased. Unfortunately randomized trials including surgery versus angioplasty are not available. It should be kept in mind that only after correction of the stenosis is achieved and the blood pressure has become normal, can the diagnosis of renovascular hypertension be made with certainty.

    2014-05-01

    Irrespective of apparent 'normal' resting blood pressure (BP), some individuals may experience an excessive elevation in BP with exercise (i.e. systolic BP ≥210 mm Hg in men or ≥190 mm Hg in women or diastolic BP ≥110 mm Hg in men or women), a condition termed exercise hypertension or a 'hypertensive response to exercise' (HRE). An HRE is a relatively common condition that is identified during standard exercise stress testing; however, due to a lack of information with respect to the clinical ramifications of an HRE, little value is usually placed on such a finding. In this review, we discuss both the clinical importance and underlying physiological contributors of exercise hypertension. Indeed, an HRE is associated with an increased propensity for target organ damage and also predicts the future development of hypertension, cardiovascular events and mortality, independent of resting BP. Moreover, recent work has highlighted that some of the elevated cardiovascular risks associated with an HRE may be related to high-normal resting BP (pre-hypertension) or ambulatory 'masked' hypertension and that an HRE may be an early warning signal of abnormal BP control that is otherwise undetected with clinic BP. Whilst an HRE may be amenable to treatment via pharmacological and lifestyle interventions, the exact physiological mechanism of an HRE remains elusive, but it is likely a manifestation of multiple factors including large artery stiffness, increased peripheral resistance, neural circulatory control and metabolic irregularity. Future research focus may be directed towards determining threshold values to denote the increased risk associated with an HRE and further resolution of the underlying physiological factors involved in the pathogenesis of an HRE.

    Negative urgency is a facet of impulsivity that reflects mood-based rash action and is associated with various maladaptive behaviors in humans. However, the underlying neural mechanisms of negative urgency are not fully understood. Several brain regions within the mesocorticolimbic pathway, as well as the neurotransmitters dopamine (DA) and serotonin (5-HT), have been implicated in impulsivity. Extracellular DA and 5-HT concentrations are regulated by DA transporters (DAT) and 5-HT transporters (SERT); thus, these transporters may be important molecular mechanisms underlying individual differences in negative urgency. The current study employed a reward omission task to model negative urgency in rats. During reward trials, a cue light signaled the non-contingent delivery of one sucrose pellet; immediately following the non-contingent reward, rats responded on a lever to earn sucrose pellets (operant phase). Omission trials were similar to reward trials, except that non-contingent sucrose was omitted following the cue light prior to the operant phase. As expected, contingent responding was higher following omission of expected reward than following delivery of expected reward, thus reflecting negative urgency. Upon completion of behavioral training, Vmax and Km were obtained from kinetic analysis of [(3)H]DA and [(3)H]5-HT uptake using synaptosomes prepared from nucleus accumbens (NAc), dorsal striatum (Str), medial prefrontal cortex (mPFC), and orbitofrontal cortex (OFC) isolated from individual rats. Vmax for DAT in NAc and for SERT in OFC were positively correlated with negative urgency scores. The current findings suggest that mood-based impulsivity (negative urgency) is associated with enhanced DAT function in NAc and SERT function in OFC. Copyright © 2015 Elsevier B.V.

    Full Text Available The objective of the present study is to determine the likelihood of injured or poisoned patients in special populations, such as those patients that are elderly and self-injurious, being seen within an emergency department’s triage nurse assigned urgency. Data from the National Hospital Ambulatory Medical Care Survey (2007 was utilized in this study. Multi-level models and multivariate linear regression models were used; patient age, sex, reported pain levels, wait time, and injury type were examined as potential predictors of being seen within assigned urgency. From a random sample across all US Emergency Departments, 5616 patients nested in 312 hospital emergency departments were included into the study. Typically, approximately 1 in 5 emergency department patients were not seen within their triage nurse assigned urgencies. The typical patient in the average hospital had an 81% likelihood of being seen within their assigned urgency. P atients who were oldest [odds ratio (OR=0.0990] and had self-inflicted injuries (vs assault OR=1.246 and OR=1.596 had the least likelihood to be seen within their assigned urgencies. As actual wait-time increased for patients, they were less likely to be seen within their assigned urgencies. The most powerful predictors of the study’s outcome were injury type and age, indicating that patients from special populations such as the elderly or those with injuries resulting from deliberate self-harm are less likely to be actually priority patients independent of triage nurse assigned urgencies.

    The aim was to determine the proportions and correlates of essential hypertension among children in a tertiary pediatric hypertension clinic. We evaluated 423 consecutive children and collected demographic and clinical history by retrospective chart review. We identified 275 (65%) hypertensive children (blood pressure >95th percentile per the "Fourth Report on the Diagnosis, Evaluation, and Treatment of High Blood Pressure in Children and Adolescents") from 423 children referred to the clinic for history of elevated blood pressure. The remainder of the patients had normotension (11%), white coat hypertension (11%), prehypertension (10%), and pending diagnosis (3%). Among the 275 hypertensive children, 43% (n = 119; boys = 56%; median age = 12 years; range = 3-17 years) had essential hypertension and 57% (n = 156; boys = 66%; median age = 9 years; range = 0.08-19 years) had secondary hypertension. When compared with those with secondary hypertension, those with essential hypertension had a significantly older age at diagnosis (P = 0.0002), stronger family history of hypertension (94% vs. 68%; P secondary hypertension. The phenotype of essential hypertension can present as early as 3 years of age and is the predominant form of hypertension in children after age of 6 years. Among children with hypertension, those with essential hypertension present at an older age, have a stronger family history of hypertension, and have lower prevalence of preterm birth. © American Journal of Hypertension, Ltd 2014.

    We studied seven hydropower license consultations to examine the role of a sense of urgency to reach agreement. Hydropower licensing consultations were studied because the statutory requirement for consultation encourages negotiation, all such consultations are similar, and a negotiated settlement is not a foregone result. Cases selected for analysis met screening criteria. Structured interviews were conducted with participants after the negotiations had been concluded. Respondent recollections were checked against the documentary record. A sense of urgency to reach agreement was a significant factor in the completion of these negotiations; where there was no shared sense of urgency, purposeful delay adversely affected the negotiations. Although a sense of urgency was experienced by at least one party in each case, only a shared sense of urgency at the end of the process proved significant. Delay did not prevent ultimate agreement but a shared sense of urgency brought speedier agreement and greater satisfaction with the negotiation.

    Objectives. To assess the clinical effectiveness and adverse effects of Zhen Gan Xi Feng Decoction (ZGXFD) for essential hypertension (EH). Methods. Five major electronic databases were searched up to August 2012 to retrieve any potential randomized controlled trials designed to evaluate the clinical effectiveness of ZGXFD for EH reported in any language, with main outcome measure as blood pressure (BP). Results. Six randomized trials were included. Methodological quality of the trials was evaluated as generally low. Four trials compared prescriptions based on ZGXFD with antihypertensive drugs. Meta-analysis showed that ZGXFD was more effective in BP control and TCM syndrome and symptom differentiation (TCM-SSD) scores than antihypertensive drugs. Two trials compared the combination of modified ZGXFD plus antihypertensive drugs with antihypertensive drugs. Meta-analysis showed that there is significant beneficial effect on TCM-SSD scores. However, no significant effect on BP was found. The safety of ZGXFD is still uncertain. Conclusions. ZGXFD appears to be effective in improving blood pressure and hypertension-related symptoms for EH. However, the evidence remains weak due to poor methodological quality of the included studies. More rigorous trials are warranted to support their clinical use.

    When deciding whether to bet in situations that involve potential monetary loss or gain (mixed gambles), a subjective sense of pressure can influence the evaluation of the expected utility associated with each choice option. Here, we explored how gambling decisions, their psychophysiological and neural counterparts are modulated by an induced sense of urgency to respond. Urgency influenced decision times and evoked heart rate responses, interacting with the expected value of each gamble. Using functional MRI, we observed that this interaction was associated with changes in the activity of the striatum, a critical region for both reward and choice selection, and within the insula, a region implicated as the substrate of affective feelings arising from interoceptive signals which influence motivational behavior. Our findings bridge current psychophysiological and neurobiological models of value representation and action-programming, identifying the striatum and insular cortex as the key substrates of decision-making under risk and urgency.

    Theoretical models of binge eating and eating disorders include both transdiagnostic and eating disorder-specific risk factors. Negative urgency (i.e., the tendency to act impulsively when distressed) is a critical transdiagnostic risk factor for binge eating, but limited research has examined interactions between negative urgency and disorder-specific variables. Investigating these interactions can help identify the circumstances under which negative urgency is most strongly associated with binge eating. We examined whether prominent risk factors (i.e., appearance pressures, thin-ideal internalization, body dissatisfaction, dietary restraint) specified in well-established etiologic models of eating disorders moderate negative urgency-binge eating associations. Further, we investigated whether phenotypic moderation effects were due to genetic and/or environmental associations between negative urgency and binge eating. Participants were 988 female twins aged 11-25 years from the Michigan State University Twin Registry. Appearance pressures, thin-ideal internalization, and body dissatisfaction, but not dietary restraint, significantly moderated negative urgency-binge eating associations, with high levels of these risk factors and high negative urgency associated with the greatest binge eating. Twin moderation models revealed that genetic, but not environmental, sharing between negative urgency and binge eating was enhanced at higher levels of these eating disorder-specific variables. Future longitudinal research should investigate whether eating disorder risk factors shape genetic influences on negative urgency into manifesting as binge eating.

    Full Text Available Background. Certain hypertension subtypes have been shown to increase the risk for cardiovascular morbidity and mortality and may be related to specific underlying genetic determinants. Inappropriate characterization of subtypes of hypertension makes efforts at elucidating the genetic contributions to the etiology of hypertension largely vapid. We report the hypertension subtypes among patients with hypertension from South-Western Nigeria. Methods. A total of 1858 subjects comprising 76% female, hypertensive, aged 18 and above were recruited into the study from two centers in Ibadan, Nigeria. Hypertension was identified using JNCVII definition and was further grouped into four subtypes: controlled hypertension (CH, isolated systolic hypertension (ISH, isolated diastolic hypertension (IDH, and systolic-diastolic hypertension (SDH. Results. Systolic-diastolic hypertension was the most prevalent. Whereas SDH (77.6% versus 73.5% and IDH (4.9% versus 4.7% were more prevalent among females, ISH (10.1% versus 6.2% was higher among males (P=0.048. Female subjects were more obese (P<0.0001 and SDH was prevalent among the obese group. Conclusion. Gender and obesity significantly influenced the distribution of the hypertension subtypes. Characterization of hypertension by subtypes in genetic association studies could lead to identification of previously unknown genetic variants involved in the etiology of hypertension. Large-scale studies among various ethnic groups may be needed to confirm these observations.

    Background Although drinking for tension reduction has long been posited as a risk factor for alcohol-related problems, studies investigating anxiety in relation to risk for alcohol problems have returned inconsistent results, leading researchers to search for potential moderators. Negative urgency (the tendency to become behaviorally dysregulated when experiencing negative affect) is a potential moderator of theoretical interest because it may increase risk for alcohol problems among those high in negative affect. The present study tested a cross-sectional mediated moderation hypothesis whereby an interactive effect of anxiety and negative urgency on alcohol problems is mediated through coping-related drinking motives. Method The study utilized baseline data from a hazardously drinking sample of young adults (N = 193) evaluated for participation in a randomized controlled trial of naltrexone and motivational interviewing for drinking reduction. Results The direct effect of anxiety on physiological dependence symptoms was moderated by negative urgency such that the positive association between anxiety and physiological dependence symptoms became stronger as negative urgency increased. Indirect effects of anxiety and negative urgency on alcohol problems (operating through coping motives) were also observed. Conclusions Although results of the current cross-sectional study require replication using longitudinal data, the findings suggest that the simultaneous presence of anxiety and negative urgency may be an important indicator of risk for AUDs via both direct interactive effects and indirect additive effects operating through coping motives. These findings have potentially important implications for prevention/intervention efforts for individuals who become disinhibited in the context of negative emotional states. PMID:26031346

    Objective Review the pharmacologic treatment options for pulmonary arterial hypertension (PAH) in the cardiac intensive care setting and summarize the most-recent literature supporting these therapies. Data Sources and Study Selection Literature search for prospective studies, retrospective analyses, and case reports evaluating the safety and efficacy of PAH therapies. Data Extraction Mechanisms of action and pharmacokinetics, treatment recommendations, safety considerations, and outcomes for specific medical therapies. Data Synthesis Specific targeted therapies developed for the treatment of adult patients with PAH have been applied for the benefit of children with PAH. With the exception of inhaled nitric oxide, there are no PAH medications approved for children in the US by the FDA. Unfortunately, data on treatment strategies in children with PAH are limited by the small number of randomized controlled clinical trials evaluating the safety and efficacy of specific treatments. The treatment options for PAH in children focus on endothelial-based pathways. Calcium channel blockers are recommended for use in a very small, select group of children who are responsive to vasoreactivity testing at cardiac catheterization. Phosphodiesterase type 5 inhibitor therapy is the most-commonly recommended oral treatment option in children with PAH. Prostacyclins provide adjunctive therapy for the treatment of PAH as infusions (intravenous and subcutaneous) and inhalation agents. Inhaled nitric oxide is the first line vasodilator therapy in persistent pulmonary hypertension of the newborn, and is commonly used in the treatment of PAH in the Intensive Care Unit (ICU). Endothelin receptor antagonists have been shown to improve exercise tolerance and survival in adult patients with PAH. Soluble Guanylate Cyclase Stimulators are the first drug class to be FDA approved for the treatment of chronic thromboembolic pulmonary hypertension. Conclusions Literature and data supporting the

    In use of their attributions, granted by the Regulation Law of the 27 Constitutional Article in Nuclear Matter, the National Commission of Nuclear Safety and Safeguards (CNSNS) it has taken charge to the authors the Politics' s elaboration and Guide of Application of Urgency measures and Administrative Sanctions (PGAMASA) with the double objective of discouraging the licensees, contractors and employees of incurring in nonfulfillment or violations to the regulator mark and of encouraging them to be attentive to the prompt identification and the immediate and appropriate correction of the violations and nonfulfillment. The present article presents the legal mark that confers the CNSNS the attributions to implant a PGAMASA and it exposes the more important elements that conform it. The urgency measures and administrative sanctions are defined, the approaches to determine the level of graveness of a violation or nonfulfillment and it is related the application process of urgency measures and administrative sanctions are presented. Like this among the urgency measures they stand out figures like the Notifications of Violation and the Regulatory Orders by their versatility and use potentiality. The PGAMASA has a basically dissuasive character and its last purpose it is to strengthen the actions that the CNSNS carries out in the fulfillment of its functions to maintain the safety standards in the operation of the nuclear facilities.

    Recognition and treatment of secondary causes of hypertension among patients with resistant hypertension may help to control blood pressure and reduce cardiovascular risk. However, there are no studies systematically evaluating secondary causes of hypertension according to the Seventh Joint National Committee. Consecutive patients with resistant hypertension were investigated for known causes of hypertension irrespective of symptoms and signs, including aortic coarctation, Cushing syndrome, obstructive sleep apnea, drugs, pheochromocytoma, primary aldosteronism, renal parenchymal disease, renovascular hypertension, and thyroid disorders. Among 125 patients (age: 52±1 years, 43% males, systolic and diastolic blood pressure: 176±31 and 107±19 mm Hg, respectively), obstructive sleep apnea (apnea-hypopnea index: >15 events per hour) was the most common condition associated with resistant hypertension (64.0%), followed by primary aldosteronism (5.6%), renal artery stenosis (2.4%), renal parenchymal disease (1.6%), oral contraceptives (1.6%), and thyroid disorders (0.8%). In 34.4%, no secondary cause of hypertension was identified (primary hypertension). Two concomitant secondary causes of hypertension were found in 6.4% of patients. Age >50 years (odds ratio: 5.2 [95% CI: 1.9-14.2]; Phypertension. Age >50 years, large neck circumference measurement, and snoring are good predictors of obstructive sleep apnea in this population.

    Neonatal hypertension (HT) is a frequently under reported condition and is seen uncommonly in the intensive care unit. Neonatal HT has defined arbitrarily as blood pressure more than 2 standard deviations above the base as per the age or defined as systolic BP more than 95% for infants of similar size, gestational age and postnatal age. It has been diagnosed long back but still is the least studied field in neonatology. There is still lack of universally accepted normotensive data for neonates as per gestational age, weight and post-natal age. Neonatal HT is an important morbidity that needs timely detection and appropriate management, as it can lead to devastating short-term effect on various organs and also poor long-term adverse outcomes. There is no consensus yet about the treatment guidelines and majority of treatment protocols are based on the expert opinion. Neonate with HT should be evaluated in detail starting from antenatal, perinatal, post-natal history, and drug intake by neonate and mother. This review article covers multiple aspects of neonatal hypertension like definition, normotensive data, various etiologies and methods of BP measurement, clinical features, diagnosis and management.

    Ischemic heart disease (IHD) is the most important cause of mortality worldwide. Although the awareness of cardiovascular risk factors and IHD in women has increased over the last decades, mortality rates are still higher in women than in men. Among traditional cardiovascular risk factors, hypertension is associated with a greater risk for IHD in women as compared to men. In this review, discuss gender differences in epidemiology and pathophysiology of hypertension and its impact on the incidence and outcomes of IHD in women. We also, discuss some "women conditions" such as hypertensive disorders in pregnancy (HDP) and polycystic ovarian syndrome (PCOS). Even though this is not a systematic review, English-language studies on MEDLINE and the Cochrane Database of Systematic reviews were searched for consultation and analysis. Hypertension display different epidemiological patterns in men and women. Studies have shown that hypertension has a different proatherogenic effects in men and women. Hypertension has a direct effect on microcirculation, but estrogens have a protective role in this regard in premenopausal women. However, after the decline in estrogen levels, women are exposed to the same cardiovascular risk as males. Postmenopausal women exhibit a greater burden of cardiovascular risk factors, which together with microvascular dysfunction and smaller and stiffer arteries conducts to the worse prognosis observed in women with IHD. "Women specific conditions" such as HDP and PCOS affects 10% of pregnant women and women in reproductive age, respectively. These conditions are associated with increased risk of hypertension and IHD later in life. Although women are more aware of their hypertension, cardiovascular mortality is higher in hypertensive women with comorbid IHD. Yet these gender disparities in outcomes seem to be attenuated with effective therapy. The pathophysiology of IHD is gender specific, women with ischemic symptoms presenting less often with

  1. Pelvic floor myofascial trigger points: manual therapy for interstitial cystitis and the urgency-frequency syndrome.

    The effectiveness of manual physical therapy was evaluated in patients with interstitial cystitis and the urethral syndrome, that is urgency-frequency with or without pelvic pain. The rationale was based on the hypothesis that pelvic floor myofascial trigger points are not only a source of pain and voiding symptoms, but also a trigger for neurogenic bladder inflammation via antidromic reflexes. From September 1995 to November 2000, 45 women and 7 men, including 10 with interstitial cystitis and 42 with the urgency-frequency syndrome, underwent manual physical therapy to the pelvic floor for 1 to 2 visits weekly for 8 to 12 weeks. Results were determined by patient completed symptom score sheets indicating the rate of improvement according to outcome parameters, including 25% to 50%-mild, 51% to 75%-moderate, 76% to 99%-marked and 100%-complete resolution. In 10 cases these subjective results were confirmed by measuring resting pelvic floor tension by electromyography before and after the treatment course. Of the 42 patients with the urgency-frequency syndrome with or without pain 35 (83%) had moderate to marked improvement or complete resolution, while 7 of the 10 (70%) with interstitial cystitis had moderate to marked improvement. The mean duration of symptoms before treatment in those with interstitial cystitis and the urgency-frequency syndrome was 14 (median 12) and 6 years (median 2.5), respectively. In patients with no symptoms or brief, low intensity flares mean followup was 1.5 years. In 10 patients who underwent electromyography mean resting pelvic floor tension decreased from 9.73 to 3.61 microV., which was a 65% improvement. Pelvic floor manual therapy for decreasing pelvic floor hypertonus effectively ameliorates the symptoms of the urgency/frequency syndrome and interstitial cystitis.

  2. Verbal collision avoidance messages during simulated driving: perceived urgency, alerting effectiveness and annoyance.

    2011-04-01

    Matching the perceived urgency of an alert with the relative hazard level of the situation is critical for effective alarm response. Two experiments describe the impact of acoustic and semantic parameters on ratings of perceived urgency, annoyance and alerting effectiveness and on alarm response speed. Within a simulated driving context, participants rated and responded to collision avoidance system (CAS) messages spoken by a female or male voice (experiments 1 and 2, respectively). Results indicated greater perceived urgency and faster alarm response times as intensity increased from -2 dB signal to noise (S/N) ratio to +10 dB S/N, although annoyance ratings increased as well. CAS semantic content interacted with alarm intensity, indicating that at lower intensity levels participants paid more attention to the semantic content. Results indicate that both acoustic and semantic parameters independently and interactively impact CAS alert perceptions in divided attention conditions and this work can inform auditory alarm design for effective hazard matching. Matching the perceived urgency of an alert with the relative hazard level of the situation is critical for effective alarm response. Here, both acoustic and semantic parameters independently and interactively impacted CAS alert perceptions in divided attention conditions. This work can inform auditory alarm design for effective hazard matching. STATEMENT OF RELEVANCE: Results indicate that both acoustic parameters and semantic content can be used to design collision warnings with a range of urgency levels. Further, these results indicate that verbal warnings tailored to a specific hazard situation may improve hazard-matching capabilities without substantial trade-offs in perceived annoyance.

    Dietary patterns consider synergistic effects compared with isolated foods or nutrients on health outcomes. The aim of this systematic review and meta-analysis was to examine the associations of diet quality as assessed by the Healthy Eating Index (HEI), the Alternate Healthy Eating Index (AHEI), and the Dietary Approaches to Stop Hypertension (DASH) score and the risk of all-cause mortality, cardiovascular mortality or incidence, cancer mortality or incidence, type 2 diabetes mellitus, and neurodegenerative diseases. A literature search was performed using the electronic databases MEDLINE, SCOPUS, and EMBASE with an end date of May 10, 2014. Study-specific risk ratios were pooled using a random effect model by the Cochrane software package Review Manager 5.2. Fifteen cohort studies (34 reports), including 1,020,642 subjects, met the criteria and were included in the meta-analysis. Diets of the highest quality, as assessed by the HEI, AHEI, and DASH score, resulted in a significant risk reduction (RR) for all-cause mortality (RR 0.78, 95% CI 0.76 to 0.80; PDiets that score highly on the HEI, AHEI, and DASH are associated with a significant reduction in the risk of all-cause mortality, cardiovascular disease, cancer, and type 2 diabetes mellitus by 22%, 22%, 15%, and 22%, respectively, and therefore is of high public health relevance.

    Full Text Available BACKGROUND: People with no previous cardiovascular events or cardiovascular disease represent a primary prevention population. The benefits and harms of treating mild hypertension in primary prevention patients are not known at present. This review examines the existing randomized controlled trial (RCT evidence. OBJECTIVE: Primary objective: To quantify the effects of antihypertensive drug therapy on mortality and morbidity in adults with mild hypertension (systolic blood pressure (BP 140-159 mmHg and/or diastolic BP 90-99 mmHg and without cardiovascular disease. METHODS: Search: We searched CENTRAL (2011, Issue 1, MEDLINE (1948 to May 2011, EMBASE (1980 to May 2011 and reference lists of articles. The Cochrane Database of Systematic Reviews and the Database of Abstracts of Reviews of Effectiveness (DARE were searched for previous reviews and meta-analyses of anti-hypertensive drug treatment compared to placebo or no treatment trials up until the end of 2011. Selection criteria: RCTs of at least 1 year duration. Data collection and analysis: The outcomes assessed were mortality, stroke, coronary heart disease (CHD, total cardiovascular events (CVS, and withdrawals due to adverse effects. MAIN RESULTS: Of 11 RCTs identified 4 were included in this review, with 8,912 participants. Treatment for 4 to 5 years with antihypertensive drugs as compared to placebo did not reduce total mortality (RR 0.85, 95% CI 0.63, 1.15.

Newly diagnosed adult hypertensives, with blood pressure 140/90mm Hg, taken twice with mercury column sphygmomanometer at 3 weeks interval, were studied. The total number of hypertensive patients treated over this period was also taken into consideration. The newly diagnosed hypertensives were classified using JNC VI classification. The frequency of occurrence of target organ damage such as Left Ventricular Hypertrophy (LVH), heart failure, renal impairment etc. was charted according to systolic and or diastolic pressures. The occurrence of systolic or diastolic blood pressure was also related with the age of the patients. Blood metabolic parameters were compared in both systolic and diastolic blood pressures for their possible contributory role. Two thousand seven hundred and ninety-two adult hypertensive patients were managed over the study period. Of them, 218 (7.8%) were newly diagnosed and studied. There were 94 males and 124 females. Seventy-seven (35.3%) were aged 60 years and above with equal frequency in the gender. One hundred and seventy-eight (81.7%) cases had combined systolic and diastolic pressures. Twenty-nine (13.3%) patients had systolic hypertension. Twenty-five (86.2%) of these 29 were aged 50 years and above and 20 (69.0%) were aged 60 years and above. Eleven (5.0%) patients had isolated diastolic hypertension and they were all in the age bracket 40-49 years. Systolic blood pressure was found to be rising with advancing age while diastolic blood pressure peaked at mid 40's and declined. Target organ damage occurred more frequently with systolic hypertension and advancing age than with diastolic hypertension. Systolic hypertension occurred more frequently in this series of adult Nigerians with hypertension. It was higher with advancing age and associated with more target organ

    Climate change can sometimes be characterized as a "creeping environmental problem"--it is complex and long-term, involves long system lags, lacks the immediacy of everyday experience and thus is hard to perceive, and feels overwhelming to most individuals. Climate change thus does not typically attain the status of an urgent concern, taking priority over other matters for individuals, organizations or in the policy arena. We review the major reasons behind this lack of urgency, and document the observed consequences of previous communication strategies, including lack of public understanding, indifference, confusion, fear and uncertainty. We find that certain emotional motivators such as fear and guilt, while oft-employed, do not actually result in improved recognition of the urgency of the issue, nor do they typically result in action. Rather, positive and engaging approaches may be more likely to achieve this goal. We propose seven strategies to improve the communication of climate change and its urgency: 1) Abide by basic communication rules and heed the warnings of communication experts; 2) Address the emotional and the temporal components of "urgency"; 3) Increase the persuasiveness of the message; 4) Use trusted messengers-broaden the circle; 5) Use opportunities well; 6) Tap into individual and cultural strengths and values; and 7) Unite and Conquer. The multi-faceted nature of the proposed strategies reflects the unique challenges of the climate change issue as well as the need to engage all levels and sectors of societies in the solution, from individuals, to businesses, to governments. These strategies and results emerged from a multi-disciplinary, academic/practitioner workshop on the topic held at NCAR in summer 2004.

    Full Text Available Purposes: To validate a teleophthalmology mobile system aimed at improving and providing eye urgency screenings in remote and poor area settings in Brazil. The system enables one or more ophthalmologists to remotely examine a patient's condition and submit a decision describing the gravity of the case. If necessary, the patient can be forwarded to a hospital for further consultation. Methods: A cellphone (Nexus One model, with a 5 megapixel camera was used to collect data and pictures from 100 randomly selected patients at the Ophthalmology Emergency Room located at the General Hospital of the Federal University of São Paulo (UNIFESP. Data was then sent remotely to an online recording system to be reviewed by an ophthalmologist who provided feedback regarding the state of ocular urgency. Results were then compared to the gold standard diagnosis provided at the hospital. Results: The diagnosis of urgency was given by two ophthalmologists: one in the hospital (gold standard and one remotely. When we compared both diagnoses we obtained results of 81.94% specificity, 92.85% sensitivity, and 85% accuracy, with a negative predictive value of 96.72%. This work also included a processing time analysis, resulting in an average time of 8.6 min per patient for remote consultations. Conclusions: This study is the first that has used only a cellphone for diagnosing the urgency of ocular cases. Based on our results, the system can provide a reliable distinction between urgent and non-urgent situations and can offer a viable alternative for the servicing of underprivileged areas. In screening techniques, the most important outcome is to identify urgent cases with a high level of sensitivity and predictive negative value. Thus, our results demonstrate that this tool is robust and we suggest that a major study aimed to verify its efficiency in resource-poor areas should be initiated.

    Overactive Bladder (OAB) is a clinical condition characterized by symptoms reported by patients. Therefore, measurement instruments based on reported information are important for understanding its impact and treatment benefits. The aim of this study was to translate, culturally adapt and validate the Urgency Questionnaire (UQ) in Portuguese. Initially, the UQ was translated and culturally adapted to Portuguese. Sixty-three volunteers were enrolled in the study and were interviewed for responding the Portuguese version of the UQ and the validated Portuguese version of the Overactive Bladder Questionnaire short-form (OABq-SF), used as the gold standard measurement for the validation process. Psychometric properties such as criterion validity, stability, and reliability were tested. Forty-six subjects were included in the symptomatic group (presence of "urgency"), and seventeen were included in the asymptomatic group (control group). There was difference between symptomatic and asymptomatic subjects on all of the subscales (p≤0.001). The UQ subscales correlated with the OABq-SF subscales (p≤0.01), except the subscale "time to control urgency" and the item "impact" from the visual analog scales (VAS). However, these scales correlated with the OABq-SF - Symptom Bother Scale. The UQ subscales demonstrated stability over time (pPortuguese version of the UQ proved to be a valid tool for the evaluation of OAB in individuals whose native language is Portuguese.

    We studied the effect of surface neuromodulation on cystometric pressure and volume parameters in women with detrusor instability or sensory urgency. Electrical current was delivered to the suprapubic region and third sacral foramina via a transcutaneous electrical nerve stimulator with sham neuromodulation control. A consecutive series of women with proved detrusor instability or sensory urgency were randomized to 3 surface neuromodulation groups. Volume and pressure parameters were the main outcomes of transcutaneous electrical nerve stimulation applied during second cystometric fill. Sham transcutaneous electrical nerve stimulation did not alter the outcome measures. However, neuromodulation delivered across the suprapubic and sacral skin effected a reduction in mean maximum height of detrusor contraction. A current which inhibits motor activity was not superior to that which inhibits sensory perception in reducing detrusor pressure. Response in sensory urgency was poor. Results from our sham controlled study suggest that short-term surface neuromodulation via transcutaneous electrical nerve stimulation may have a role in the treatment of detrusor instability. Future studies must examine the clinical effect of long-term surface neuromodulation.

    Hypertensive crisis is a medical emergency that can cause acute damage to multiple end-organs. However, relatively little is known on the etiology, treatment, and outcomes of hypertensive crisis in Korean children. The aim of this study was to determine the etiologies and efficacy of drugs for hypertensive crisis in children during the past 5 years at a single center in Korea. We analyzed data from 51 children with hypertensive crisis during the period between January 1, 2010 and April 1, 2014. The patients were divided into two groups: those diagnosed with a hypertensive emergency (hypertension with organ injury, n = 31) and those diagnosed with a hypertensive urgency (hypertension without organ injury, n = 20). Baseline etiologies and risk factors were compared between the two groups. In addition, systolic and diastolic blood pressures were evaluated at 1, 2, 4, and 5 hours after the administration of intravenous antihypertensive drugs. Kidney injury and cancer were the common causes in patients with hypertensive crisis. Cardiovascular complications (cardiac hypertrophy) (p = 0.002), central nervous system complications (p = 0.004), and retinopathy (p = 0.034) were more frequently observed in children with hypertensive emergency than those with hypertensive urgency. However, the proportion of renal complications was similar in both groups. Hydralazine was most commonly used in both groups to control acute increasing blood pressure at first. However, it was often ineffective for controlling abrupt elevated blood pressure. Therefore, intravenous antihypertensive drugs were changed from hydralazine to nicardipine, labetalol, or nitroprusside to control the high blood pressure in 45.1 % of the patients. Particularly, in patients with hypertensive crisis, there was no significant difference in reduction of systolic and diastolic blood pressure and in improvement of clinical outcomes between nicardipine and labetalol administration.

    Despite improvements in hypertension awareness and treatment, 30%-60% of hypertensive patients do not achieve BP targets and subsequently remain at risk for target organ damage. This therapeutic gap is particularly important to nephrologists, who frequently encounter treatment-resistant hypertension in patients with CKD. Data are limited on how best to treat patients with CKD and resistant hypertension, because patients with CKD have historically been excluded from hypertension treatment trials. First, we propose a consistent definition of resistant hypertension as BP levels confirmed by both in-office and out-of-office measurements that exceed appropriate targets while the patient is receiving treatment with at least three antihypertensive medications, including a diuretic, at dosages optimized to provide maximum benefit in the absence of intolerable side effects. Second, we recommend that each patient undergo a standardized, stepwise evaluation to assess adherence to dietary and lifestyle modifications and antihypertensive medications to identify and reduce barriers and discontinue use of substances that may exacerbate hypertension. Patients in whom there is high clinical suspicion should be evaluated for potential secondary causes of hypertension. Evidence-based management of resistant hypertension is discussed with special considerations of the differences in approach to patients with and without CKD, including the specific roles of diuretics and mineralocorticoid receptor antagonists and the current place of emerging therapies, such as renal denervation and baroreceptor stimulation. We endorse use of such a systematic approach to improve recognition and care for this vulnerable patient group that is at high risk for future kidney and cardiovascular events.

    Full Text Available Hypertension is the most common medical problem encountered during pregnancy, complicating 2-3% of pregnancies. Hypertensive disorders during pregnancy are classified into 4 categories: chronic hypertension, pre-eclampsia/eclampsia, pre-eclampsia superimposed on chronic hypertension, and gestational hypertension. A relative paucity of investigative data, as well as the frequent difficulty in making an etiological diagnosis, may lead to problems in its management. This case report analyses current concepts regarding the hypertensive disorders of gestation, focusing on chronic hypertension. Chronic hypertension is defined as blood pressure exceeding 140/90 mmHg before pregnancy or before 20 weeks gestation. Hypertensive disorders in pregnancy may cause maternal and fetal morbidity and remain a leading source of maternal mortality. A prompt diagnosis is needed also because hypertension may be an indicator of pre-eclampsia, a condition which can evolve into serious complications. Maintaining blood pressure below 140/90 mmHg is recommended, although treatment should be determined on an individual basis. Many anti-hypertensive agents appear to be safe for use during pregnancy: methildopa has been the most studied of the anti-hypertensive drugs and has the best safety record. Labetalol, idralazine and nifedipine also have been found to be safe; ACE-inhibitors are absolutely contraindicated, because they are associated with intrauterine growth retardation.

    Full Text Available Introduction: Hypertensive retinopathy describes a spectrum of retinal changes in patients with elevated blood pressure (BP. It is unknown why some patients are more likely to develop acute ocular end-organ damage than others with similar BP. We examined risk factors for grade III/IV hypertensive retinopathy among patients with hypertensive urgency in the emergency department (ED and compared healthcare utilization and mortality between patients with and without grade III/IV hypertensive retinopathy.Methods: A preplanned subanalysis of patients who presented to a university hospital ED with diastolic BP > 120 mmHg and who enrolled in the Fundus Photography versus Ophthalmoscopy Trial Outcomes in the ED study was performed. Bilateral nonmydriatic ocular fundus photographs, vital signs, and demographics were obtained at presentation. Past medical history, laboratory values, healthcare utilization, and mortality were ascertained from medical record review at least 8 months after initial ED visit.Results: Twenty-one patients with diastolic BP > 120 mmHg, 7 of whom (33% had grade III/IV hypertensive retinopathy, were included. Patients with retinopathy were significantly younger than those without (median 33 vs 50 years, P = 0.02. Mean arterial pressure (165 vs 163 mmHg was essentially equal in the 2 groups. Patients with retinopathy had substantially increased but nonsignificant rates of ED revisit (57% vs 29%, P = 0.35 and hospital admission after ED discharge (43% vs 14%, P = 0.28. One of the patients with retinopathy died, but none without.Conclusion: Younger patients may be at higher risk for grade III/IV hypertensive retinopathy among patients with hypertensive urgency. Chronic compensatory mechanisms may have not yet developed in these younger patients. Alternatively, older patients with retinopathy may be underrepresented secondary to increased mortality among these patients at a younger age (survivorship bias. Further research is needed to

    2016-01-01

    Full Text Available Hypertension is a  very common disease with high morbidity and reduction in quality of life. Endocrine disorders are the most common cause of secondary hypertension affecting ~3% of the population. Primary aldosteronism can be the cause of endocrine hypertension more often than other endocrine disorders. Other less common causes of endocrine hypertension include Cushing syndrome, pheochromocytoma, thyroid disorders, and hyperparathyroidism. Endocrine hypertension is potentially curable if the underlying cause is identified and treated accordingly. Younger age at manifestation of resistance to multiple antihypertensive drugs, together with other clinical signs of an endocrine disorder, should raise the suspicion and prompt the appropriate evaluation.

  11. Sacral Nerve Stimulation For Urinary Urge Incontinence, Urgency-Frequency, Urinary Retention, and Fecal Incontinence

    Science.gov (United States)

    2005-01-01

    Executive Summary Objective The aim of this review was to assess the effectiveness, safety, and cost of sacral nerve stimulation (SNS) to treat urinary urge incontinence, urgency-frequency, urinary retention, and fecal incontinence. Background: Condition and Target Population Urinary urge incontinence, urgency-frequency, urinary retention, and fecal incontinence are prevalent, yet rarely discussed, conditions. They are rarely discussed because patients may be uncomfortable disclosing their symptoms to a health professional or may be unaware that there are treatment options for these conditions. Briefly, urge incontinence is an involuntary loss of urine upon a sudden urge. Urgency-frequency is an uncontrollable urge to void, which results in frequent, small-volume voids. People with urgency-frequency may or may not also experience chronic pelvic pain. Urinary retention refers to the inability to void despite having the urge to void. It can be caused by a hypocontractile detrusor (weak or no bladder muscle contraction) or obstruction due to urethral overactivity. Fecal incontinence is a loss of voluntary bowel control. The prevalence of urge incontinence, urgency-frequency, and urinary retention in the general population is 3.3% to 8.2%, and the prevalence of fecal incontinence is 1.4% to 1.9%. About three-quarters of these people will be successfully treated by behaviour and/or drug therapy. For those who do not respond to these therapies, the options for treatment are management with diapers or pads, or surgery. The surgical procedures are generally quite invasive, permanent, and are associated with complications. Pads and/or diapers are used throughout the course of treatment as different therapies are tried. Patients who respond successfully to treatment may still require pads or diapers, but to a lesser extent. The Technology Being Reviewed: Sacral Nerve Stimulation Sacral nerve stimulation is a procedure where a small device attached to an electrode is

  12. Pulmonary arterial hypertension

    Science.gov (United States)

    2013-01-01

    Pulmonary arterial hypertension (PAH) is a chronic and progressive disease leading to right heart failure and ultimately death if untreated. The first classification of PH was proposed in 1973. In 2008, the fourth World Symposium on PH held in Dana Point (California, USA) revised previous classifications. Currently, PH is devided into five subgroups. Group 1 includes patients suffering from idiopathic or familial PAH with or without germline mutations. Patients with a diagnosis of PAH should systematically been screened regarding to underlying mutations of BMPR2 gene (bone morphogenetic protein receptor type 2) or more rarely of ACVRL1 (activine receptor-like kinase type 1), ENG (endogline) or Smad8 genes. Pulmonary veno occusive disease and pulmonary capillary hemagiomatosis are individualized and designated as clinical group 1'. Group 2 'Pulmonary hypertension due to left heart diseases' is divided into three sub-groups: systolic dysfonction, diastolic dysfonction and valvular dysfonction. Group 3 'Pulmonary hypertension due to respiratory diseases' includes a heterogenous subgroup of respiratory diseases like PH due to pulmonary fibrosis, COPD, lung emphysema or interstitial lung disease for exemple. Group 4 includes chronic thromboembolic pulmonary hypertension without any distinction of proximal or distal forms. Group 5 regroup PH patients with unclear multifactorial mechanisms. Invasive hemodynamic assessment with right heart catheterization is requested to confirm the definite diagnosis of PH showing a resting mean pulmonary artery pressure (mPAP) of ≥ 25 mmHg and a normal pulmonary capillary wedge pressure (PCWP) of ≤ 15 mmHg. The assessment of PCWP may allow the distinction between pre-capillary and post-capillary PH (PCWP > 15 mmHg). Echocardiography is an important tool in the management of patients with underlying suspicion of PH. The European Society of Cardiology and the European Respiratory Society (ESC-ERS) guidelines specify its role

    Extracorporeal shock-wave lithotripsy (ESWL) is an effective and relatively non-invasive treatment modality for ureteral or renal calculi. Although it has been accepted as a safe procedure, minor and major complications have been reported after ESWL. Spontaneous renal artery dissection (SRAD) is a rare and usually misdiagnosed condition because of non-specific presentation of the patients. Depending on the severity of the extent of the dissection non-operative or surgical treatment modalities could be performed. We represent a patient with complaints of bilateral flank pain, hematuria and hypertensive urgency who was diagnosed as having bilateral SRAD possibly secondary to ESWL and chronic hypertension.

    The management of some orthopaedic extremity injuries has changed over the past decade because of changing resource availability and the risks of complications. It is helpful to review the current literature regarding orthopaedic extremity emergencies and urgencies. The effects of the techniques of damage control orthopaedic techniques and the concept of the orthopaedic trauma room have also affected the management of these injuries. The available literature indicates that the remaining true orthopaedic extremity emergencies include compartment syndrome and vascular injuries associated with fractures and dislocations. Orthopaedic urgencies include open fracture management, femoral neck fractures in young patients treated with open reduction and internal fixation, and talus fractures that are open or those with impending skin compromise. Deciding when the definitive management of orthopaedic extremity injuries will occur has evolved as the concept of damage control orthopaedics has become more commonly accepted. Patient survival rates have improved with current resuscitative protocols. Definitive fixation of extremity injuries should be delayed until the patient's physiologic and extremity soft-tissue status allows for appropriate definitive management while minimizing the risks of complications. In patients with semiurgent orthopaedic injuries, the use of an orthopaedic trauma room has led to more efficient care of patients, fewer complications, and better time management for surgeons who perform on-call service for patients with traumatic orthopaedic injuries.

    Management of patients with severe hypertension without progressive target organ damage remains controversial. Some guidelines mentioned oral anti-hypertensive medication as a treatment to reduce blood pressure in the emergency department, while others recommended against such treatment. To review the management ofpatients with severe hypertension without progressive target organ damage in the emergency department, Maharaj Nakorn Chiang Mai hospital. In a retrospective descriptive analysis study, medical records ofadult patients diagnosed with severe hypertension without progressive target organ damage between January 2011 and December 2012 were reviewed. Patient demographics, data on management including investigation sent and treatment given were collected. Statistical analysis was done by using descriptive statistics and Kruskal-Wallis one-way analysis of variance test. One hundred fifty one medical records were reviewed. Four oral anti-hypertensive medication were used to reduce blood pressure, Amlodipine, Captopril, Hydralazine, and Nifedipine. There were no significant diference between each medication in terms of their effect on bloodpressure reduction (p = 0.513). No side effect or other complications from the use of oral anti-hypertensive medication were recorded The choice of medication used for the treatment of hypertensive urgency ranged from Amlodipine, Captopril, Hydralazine, and Nifedipine, which varied in dosage. However their efficacies were the same when compared with each other and none produced any notable side effects.

    To determine whether the effects of negative urgency, a unique facet of impulsivity marked by engaging in potentially unhealthy and rash behaviors in order to cope with anxiety or negative moods, on drinking behavior can be explained by positive and negative alcohol outcome expectancies and specific drinking motives (i.e., coping and enhancement). College students (N=194) completed web-based surveys in exchange for course credit. Students completed measures of negative urgency, comprehensive effects of alcohol, drinking motives, and alcohol use behaviors. Results of path analysis indicated significant indirect effects of negative urgency and alcohol use through both alcohol outcome expectancies and enhancement motives. The effects of enhancement motives on drinking were mediated by positive alcohol outcome expectancies. The effects of coping motives on drinking were not attributable to negative expectancies. Individuals high on negative urgency may consume alcohol in order to ameliorate their emotional distress due to strong desires to increase positive and decrease negative experiences associated with drinking. Emotion-focused impulsivity's influence on drinking outcomes can be ascribed to enhancement motives for drinking as well as positive and negative alcohol outcome expectancies. Prevention efforts should target drinking motives and alcohol outcome expectancies among those higher in negative urgency. Copyright © 2016 Elsevier Ltd. All rights reserved.

  18. Is it a matter of urgency? A survey of assessments by walk-in patients and doctors of the urgency level of their encounters at a general emergency outpatient clinic in Oslo, Norway.

    Emergency room (ER) use is increasing in several countries. Variability in the proportion of non-urgent ER visits was found to range from 5 to 90 % (median 32 %). Non-urgent emergency visits are considered an inappropriate and inefficient use of the health-care system because they may lead to higher expenses, crowding, treatment delays, and loss of continuity of health care provided by a general practitioner. Urgency levels of doctor-walk-in patient encounters were assessed based on their region of origin in a diverse Norwegian population. An anonymous, multilingual questionnaire was distributed to all walk-in patients at a general emergency outpatient clinic in Oslo during two weeks in September 2009. We analysed demographic data, patient-doctor assessments of the level of urgency, and the results of the consultation. We used descriptive statistics to obtain frequencies with 95 % confidence interval (CI) for assessed levels of urgency and outcomes. Concordance between the patients' and doctors' assessments was analysed using a Kendall tau-b test. We used binary logistic regression modelling to quantify associations of explanatory variables and outcomes according to urgency level assessments. The analysis included 1821 walk-in patients. Twenty-four per cent of the patients considered their emergency consultation to be non-urgent, while the doctors considered 64 % of encounters to be non-urgent. The concordance between the assessments by the patient and by their doctor was positive but low, with a Kendall tau-b coefficient of 0.202 (p < 0.001). Adjusted logistic regression analysis showed that patients from Eastern Europe (odds ratio (OR) = 3.04; 95 % CI 1.60-5.78), Asia and Turkey (OR = 4.08; 95 % CI 2.43-6.84), and Africa (OR = 8.47; 95 % CI 3.87-18.5) reported significantly higher urgency levels compared with Norwegians. The doctors reported no significant difference in assessment of urgency based on the patient's region of origin, except

    Non-communicable diseases are the leading causes of global burden of diseases, and hypertension is one of the most important risk factors. Hypertension prevalence doubled in China in the past decade and affects more than 300 million Chinese people. In the review we systematically searched peer-reviewed publications that link health system level factors with hypertension management in China and provide the current knowledge on how to improve a country's health system to manage the hypertension epidemic. A framework was developed to guide the review. The database of PubMed, CNKI were systematically searched from inception to April 13, 2016. Two authors independently screened the searched results for inclusion, conducted data extraction and appraised the quality of studies. Key findings were described according to the framework. Five hundred seventy-two publications were identified, where 11 articles were left according to the inclusion and exclusion criteria. The study periods range from 2010 to 2015. All about 11 researches linked health system factors to the outcome of hypertension management. And the outcomes were just focused on the awareness, treatment and control of hypertension but not hypertension incidence. One study is about the role of health system governance, investigating the performance of different organized community health care centers; three studies were about health financing comparing differences in insurance coverage; three studies were about health information practicing the hypertension guidelines of China or the WHO, and the rest three about mechanisms of health service delivery. No researches were identified about physical resources for health and human resources for health. Hypertension prevalence has been rising rapidly in China and the management of hypertension in China is a detection problem rather than treatment problem. Limited evidence shows the positive effect of health system factors on hypertension management and joint efforts

    Noncirrhotic portal hypertension represents a heterogeneous group of liver disorders that is characterized by portal hypertension in the absence of cirrhosis. The purpose of this review is to serve as a guide on how to approach a patient with noncirrhotic portal hypertension with a focus on recent developments. Recent studies pertaining to noncirrhotic portal hypertension have investigated aetiological causes, mechanisms of disease, noninvasive diagnostic modalities, clinical characteristics in the paediatric population and novel treatment targets. Noncirrhotic portal hypertension is an underappreciated clinical entity that can be difficult to diagnosis without a healthy suspicion. Diagnosis then relies on a comprehensive understanding of the causes and clinical manifestations of this disease, as well as a careful interpretation of the liver biopsy. Noninvasive approaches to diagnosis may play a significant role moving forward in this disease. Treatment in NCPH remains largely targeted at the individual sequalae of portal hypertension.

    2013-02-01

    The present review examines the types of hypertension that women may suffer throughout life, their physiopathological characteristics and management. In early life, the currently used low-dose oral contraceptives seldom cause hypertension. Pregnancy provokes preeclampsia, its main medical complication, secondary to inadequate transformation of the spiral arteries and the subsequent multisystem endothelial damage caused by deportation of placental factors and microparticles. Hypertension in preeclampsia is an epiphenomenon which needs to be controlled at levels that reduce maternal risk without impairing placental perfusion. The hemodynamic changes of pregnancy may unmask a hypertensive phenotype, may exacerbate a chronic hypertension, or may complicate hypertension secondary to lupus, renovascular lesions, and pheochromocytoma. On the other hand a primary aldosteronism may benefit from the effect of progesterone and present as a postpartum hypertension. A hypertensive pregnancy, especially preeclampsia, represents a risk for cardiac, vascular and renal disease in later life. Menopause may mimic a pheochromocytoma, and is associated to endothelial dysfunction and salt-sensitivity. Among women, non-pharmacological treatment should be forcefully advocated, except for sodium restriction during pregnancy. The blockade of the renin-angiotensin system should be avoided in women at risk of pregnancy; betablockers could be used with precautions during pregnancy; diuretics, ACE inhibitors and angiotensin receptor antagonists should not be used during breast feeding. Collateral effects of antihypertensives, such as hyponatremia, cough and edema are more common in women. Thus, hypertension in women should be managed according to the different life stages.

    A 40-year-old man presented to our institution with a few-month history of increased urinary frequency, urgency and voiding difficulty. He had severe lower urinary tract symptoms with an International Prostate Symptom Score of 28 and quality of life score of 6. The mean urinary frequency and voided volume was 20 times per day and 150 ml, respectively. Abdominal ultrasonography and pelvic magnetic resonance imaging revealed the prostate measuring 15 cm3 with a 3 cm midline cyst which compressed the posterior of the bladder wall. A subsequent examination indicated that his lower urinary tract symptoms could be attributed to the cystic mass which mainly affected his storage symptoms. The patient underwent transurethral unroofing of the prostate cyst. Immediately after the surgery, his storage symptoms were improved greatly. The voiding volume was increased to 250 ml, and the frequency of urination was decreased to 8 times. No recurrent symptoms were found for seven months after the surgery.

  9. Time-Lag in Responses of Birds to Atlantic Forest Fragmentation: Restoration Opportunity and Urgency.

    There are few opportunities to evaluate the relative importance of landscape structure and dynamics upon biodiversity, especially in highly fragmented tropical landscapes. Conservation strategies and species risk evaluations often rely exclusively on current aspects of landscape structure, although such limited assumptions are known to be misleading when time-lag responses occur. By relating bird functional-group richness to forest patch size and isolation in ten-year intervals (1956, 1965, 1978, 1984, 1993 and 2003), we revealed that birds with different sensitivity to fragmentation display contrasting responses to landscape dynamics in the Brazilian Atlantic Forest. For non-sensitive groups, there was no time-lag in response: the recent degree of isolation best explains their variation in richness, which likely relates to these species' flexibility to adapt to changes in landscape structure. However, for sensitive bird groups, the 1978 patch area was the best explanatory variable, providing evidence for a 25-year time-lag in response to habitat reduction. Time-lag was more likely in landscapes that encompass large patches, which can support temporarily the presence of some sensitive species, even when habitat cover is relatively low. These landscapes potentially support the most threatened populations and should be priorities for restoration efforts to avoid further species loss. Although time-lags provide an opportunity to counteract the negative consequences of fragmentation, it also reinforces the urgency of restoration actions. Fragmented landscapes will be depleted of biodiversity if landscape structure is only maintained, and not improved. The urgency of restoration action may be even higher in landscapes where habitat loss and fragmentation history is older and where no large fragment remained to act temporarily as a refuge.

    2017-03-01

    A novel case is reported of upper gastrointestinal (UGI) bleeding from sinistral portal hypertension, caused by a left gastric artery (LGA) pseudoaneurysm (PA) compressing the splenic vein (SV) that was successfully treated with PA embolization. A 41-year-old man with previous medical history of recurrent, alcoholic pancreatitis presented with several episodes of hematemesis and abdominal pain for 48 hours. Physical examination revealed a soft abdomen, with no abdominal bruit, no pulsatile abdominal mass, and no stigmata of chronic liver disease. The hemoglobin declined acutely from 12.3 to 9.3 g/dL. Biochemical parameters of liver function and routine coagulation profile were entirely within normal limits. Abdominal CT revealed a 5-cm-wide peripancreatic mass compressing the stomach and constricting the SV. Esophagogastroduodenoscopy showed blood oozing from portal hypertensive gastropathy, small nonbleeding gastric cardial and fundal varices, gastric compression from the extrinsic mass, and no esophageal varices. MRCP and angiography showed that the mass was vascular, arose from the LGA, compressed the mid SV without SV thrombosis, and caused sinistral portal hypertension. At angiography, the PA was angioembolized and occluded. The patient has been asymptomatic with no further bleeding and a stable hemoglobin level during 8 weeks of follow-up. Literature review of the 14 reported cases of LGA PA revealed that this report of acute UGI bleeding from sinistral portal hypertension from a LGA PA constricting the SV is novel; one previously reported patient had severe anemia without acute UGI bleeding associated with sinistral portal hypertension from a LGA PA. A patient presented with UGI bleeding from sinistral portal hypertension from a LGA PA compressing the SV that was treated by angiographic obliteration of the PA which relieved the SV compression and arrested the UGI bleeding. Primary therapy for this syndrome should be addressed to obliterate the PA and not

    2017-07-01

    Here, we review current concepts on hypertensive crisis (HTN-C) with a focus on epidemiology, causes, pathophysiology and prognosis. We also offer a practical approach to the management of HTN-C. HTN-C is characterized by a severe and abrupt increase in blood pressure (BP) with impending or progressive acute end-organ damage (EOD). HTN-C can be divided into hypertensive emergency (HTN-E) and hypertensive urgency (HTN-U) based on the presence or absence of acute EOD, respectively. Recent retrospective studies have demonstrated that emergency department (ED) referrals from an outpatient clinic or rapid BP-lowering strategies in the ED do not lead to improved outcomes in patients with HTN-U. HTN-C can be a de-novo manifestation or a complication of essential or secondary HTN. The presence of acute EOD is a major poor prognostic indicator in HTN-C. The main objectives of the management of HTN-C are distinction of HTN-E from HTN-U and appropriate risk stratification, prevention or regression of acute EOD due to severely elevated BP, prevention of recurrence of HTN-C with an effective long-term management plan and avoidance of rapid lowering of BP except in some special circumstances. The majority of patients with asymptomatic HTN-U can be safely managed in the outpatient setting without exposing them to the risks of aggressive BP lowering. However, patients with HTN-E require hospitalization, prompt treatment and close monitoring.

    Abstract Cervical spondylosis and hypertension are all common diseases, but the relationship between them has never been studied. Patients with cervical spondylosis are often accompanied with vertigo. Anterior cervical discectomy and fusion is an effective method of treatment for cervical spondylosis with cervical vertigo that is unresponsive to conservative therapy. We report 2 patients of cervical spondylosis with concomitant cervical vertigo and hypertension who were treated successfully with anterior cervical discectomy and fusion. Stimulation of sympathetic nerve fibers in pathologically degenerative disc could produce sympathetic excitation, and induce a sympathetic reflex to cause cervical vertigo and hypertension. In addition, chronic neck pain could contribute to hypertension development through sympathetic arousal and failure of normal homeostatic pain regulatory mechanisms. Cervical spondylosis may be one of the causes of secondary hypertension. Early treatment for resolution of symptoms of cervical spondylosis may have a beneficial impact on cardiovascular disease risk in patients with cervical spondylosis. PMID:25761188

    Hypertension is an important modifiable risk factor for cardiovascular (CV) morbidity and mortality, and a highly prevalent condition in both men and women. However, the prevalence of hypertension is predicted to increase more among women than men. Combined oral contraceptives (COCs) can induce hypertension in a small group of women and, increase CV risk especially among those with hypertension. Both COC-related increased CV risk and blood pressure (BP) returns to pretreatment levels by 3 months of its discontinuation. The effects of menopause and hormone replacement therapy (HRT) on BP are controversial, and COCs and HRT containing the new generation progestin drospirenone are preferred in women with established hypertension. Despite the high incidence of cancer in women, CV disease remains the major cause of death in women and comparable benefit of antihypertensive treatment have been demonstrated in both women and men.

    Through our research into the design and evaluation of technology systems to improve the quality and safety of clinical communication, we have discovered that physicians and nurses differ in perspective regarding clinical prioritization and desirable response times. This has a number of important consequences including unnecessary interruptions, escalating conflict and deterioration in interprofessional relationships. Understanding the differing perspectives on clinical prioritization, or the gap in perceived urgency, may improve interprofessional relationships. We conducted a mixed-methods study utilizing both qualitative (semi-structured interviews) and quantitative (surveys) methods to determine the gap between perceived urgency among physicians and nurses. The survey comprised of real messages extracted from the clinical communication system that was implemented. Physicians and nurses reviewed the messages and assigned an urgency level to each. The semi-structured interviews used open-ended questions to act as a guide to highlight key themes of interest. Thematic analysis, frequency tabulation, and triangulation were used to analyze the data. Although the surveys demonstrated concordance between physicians and nurses when independently ranking the urgency of clinical messages (kappa=0.66 SE 0.15), agreement was only fair in comparison to the urgency identified by the original nurse who sent the message (kappa=0.22 SE 0.18). We hypothesize that clinical context has a major role in defining urgency and may explain this finding. The survey data was triangulated with the semi-structured interview data and it was determined that the desired response time significantly impacted the sender's message prioritization. For example, shift changes and anxious family members were associated with discordant prioritizations. This study demonstrated that the perceived communication urgency gap between sending nurses and receiving physicians was primarily related to timeframe

    Hypertension holds a unique place in population health and health care because it is the leading cause of cardiovascular disease and the most common noncommunicable condition seen in primary care worldwide. Without effective prevention and control, raised blood pressure significantly increases the risk of stroke, myocardial infarction, chronic kidney disease, heart failure, dementia, renal failure, and blindness. There is an urgent need for stakeholders-including individuals and families-across the health system, researchers, and decision makers to work collaboratively for improving prevention, screening and detection, diagnosis and evaluation, awareness, treatment and medication adherence, management, and control for people with or at high risk for hypertension. Meeting this need will help reduce the burden of hypertension-related disease, prevent complications, and reduce the need for hospitalization, costly interventions, and premature deaths. This review aims to synthesize evidence on the epidemiological landscape and control of hypertension in Cameroon, and to identify elements that could potentially inform interventions to combat hypertension in this setting and elsewhere in sub-Saharan Africa. The full search process will involve several steps, including selecting relevant databases, keywords, and Medical Subject Headings (MeSH); searching for relevant studies from the selected databases; searching OpenGrey and the Grey Literature Report for gray literature; hand searching in Google Scholar; and soliciting missed publications (if any) from relevant authors. We will select qualitative, quantitative, or mixed-methods studies with data on the epidemiology and control of hypertension in Cameroon. We will include published literature in French or English from electronic databases up to December 31, 2016, and involving adults aged 18 years or older. Both facility and population-based studies on hypertension will be included. Two reviewers of the team will

    To estimate the magnitude of hypertension, and its levels of awareness and control of hypertension among a community of Jordanian aborigines in Northern Jordan; and to compare the study findings with findings from other Jordanian communities. A systematic sample of 50% of all households of Qafqafa, Northern Jordan was selected and all members of the selected households were included in the study at Qafqafa Health Center, Qafqafa, Jordan. A structured questionnaire was administered to all study participants and measurement of blood pressure was performed according to a preset criteria. Data on 366 subjects included in the sample were collected during the months of April and May 2002. A total of 40 subjects or 10.9% were suffering from hypertension. Prevalence rate of hypertension was significantly lower than the 16.1% and 16.3% prevalence rates reported from other more modernized Jordanian communities. Logistic regression analysis indicated that hypertension was positively associated with masculinity, age, illiteracy, obesity, and with positive family history of hypertension. No association was detected between hypertension and each of smoking, Diabetes mellitus, and total serum cholesterol. This study showed that one-half (47.5%) of hypertensives were unaware of their diagnosis and more than one-half (57.1%) of those aware of their diagnosis did not achieve control of their hypertension. Population of the study community has significantly lower levels of hypertension than both semi-urban and recently urbanized Jordanian communities, and much of the rise in blood pressure levels is attributed to environmental factors. Moreover, hypertension management programs in Jordan are far below the optimal standards.

    Full text: The right heart catheterization is the gold standard in the diagnosis and determines the severity of pulmonary hypertension. The significant technical progress of noninvasive diagnostic imaging methods significantly improves the pixel density and spatial resolution in the study of cardiovascular structures, thus changes their role and place in the overall diagnostic plan. Learning points: What is the etiology, clinical manifestation and general pathophysiological disorders in pulmonary hypertension. What are the established diagnostic methods in the diagnosis and follow-up of patients with pulmonary hypertension. What is the recommended protocol for CT scanning for patients with clinically suspected or documented pulmonary hypertension. What are the important diagnostic findings in CT scan of a patient with pulmonary hypertension. Discussion: The prospect of instantaneous complex - anatomical and functional cardiopulmonary and vascular diagnostics seems extremely attractive. The contrast enhanced multislice computed (CT ) and magnetic resonance imaging are very suitable methods for imaging the structures of the right heart, with the possibility of obtaining multiple projections and three-dimensional imaging reconstructions . There are specific morphological features that, if carefully analyzed, provide diagnostic information. Thus, it is possible to avoid or at least reduce the frequency of use of invasive diagnostic cardiac catheterization in patients with pulmonary hypertension. Conclusion: This review focuses on the use of contrast-enhanced CT for comprehensive evaluation of patients with pulmonary hypertension and presents the observed characteristic changes in the chest, lung parenchyma , the structures of the right half of the heart and pulmonary vessels

    Secondary hypertension occurs in a significant proportion of adult patients (~10%). In young patients, renal causes (glomerulonephritis) and coarctation of the aorta should be considered. In older patients, primary aldosteronism, obstructive sleep apnoea and renal artery stenosis are more prevalent than previously thought. Primary aldosteronism can be screened by taking morning aldosterone and renin levels, and should be considered in patients with severe, resistant or hypokalaemia-associated hypertension. Symptoms of obstructive sleep apnoea should be sought. Worsening of renal function after starting an angiotensin-converting enzyme inhibitor suggests the possibility of renal artery stenosis. Recognition, diagnosis and treatment of secondary causes of hypertension lead to good clinical outcomes and the possible reversal of end-organ damage, in addition to blood pressure control. As most patients with hypertension are managed at the primary care level, it is important for primary care physicians to recognise these conditions and refer patients appropriately.

    To identify which independent variable would be strong predictor of febrile urinary tract infection (UTI) in children and adolescents with overactive bladder. A search was made of the institute's database for all patients diagnosed with overactive bladder over the preceding four years. Children and adolescents under 18 years of age with overactive bladder and no neurological or anatomical alterations of the lower urinary tract were included in the study. The independent variables were: sex, age, ethnicity (Brazilians of African descendence/others), the presence of urinary urgency, daytime incontinence, enuresis, frequent urination, infrequent voiding (≤3 voids/day), nocturia, holding maneuvers, straining to void, intermittent urinary flow, constipation and encopresis. An analysis was conducted to identify patients with febrile UTI and subsequently determine predictors of this condition. Univariate and multivariate analyses were performed. Overall, 326 patients (214 girls/112 boys) were evaluated. The mean age of the patients was 7.7±3.19 years (± standard deviation). The incidence of febrile UTI was 39.2%. Being female and infrequent voiding were factors significantly associated with febrile UTI, both in the univariate and multivariate analyses. These results show that being female and infrequent voiding constituted significant risk factors for a diagnosis of febrile UTI in these children.

    2016-05-01

    We tested a theoretical model concerning the role of attentional bias and negative affect in food consumption that offers important advances. We hypothesized that the effects of negative affect manipulations on food consumption vary as a function of trait levels of negative urgency (NU; tendency to act impulsively when distressed), and attentional bias and that the roles of emotional arousal and negative emotional valence differ and should be studied separately. 190 undergraduate women were randomly assigned to either an anger or neutral mood condition. Women in both conditions completed the Food Stroop, in which the presentation of food and neutral words were counterbalanced. After the task, participants were given the opportunity to eat mandarin oranges and/or chocolate candy while the experimenter was out of the room. The type and quantity of food consumed was counted after the participant departed. As hypothesized, the roles of emotional arousal and valence differed and the effect of the induced emotion was moderated by NU. Women high in NU who experienced emotional arousal were more likely to eat candy and consumed more candy than other women. Emotional valence had no effect on candy consumption. Neither increases in emotional arousal or emotional valence influenced attentional bias to food cues. Attentional bias was also unrelated to food consumption. The impact of negative mood inductions on palatable food consumption appears to operate through emotional arousal and not negative emotional valence, and it may operate primarily for women high in NU.

  6. Biology of portal hypertension.

    Science.gov (United States)

    McConnell, Matthew; Iwakiri, Yasuko

    2018-02-01

    Portal hypertension develops as a result of increased intrahepatic vascular resistance often caused by chronic liver disease that leads to structural distortion by fibrosis, microvascular thrombosis, dysfunction of liver sinusoidal endothelial cells (LSECs), and hepatic stellate cell (HSC) activation. While the basic mechanisms of LSEC and HSC dysregulation have been extensively studied, the role of microvascular thrombosis and platelet function in the pathogenesis of portal hypertension remains to be clearly characterized. As a secondary event, portal hypertension results in splanchnic and systemic arterial vasodilation, leading to the development of a hyperdynamic circulatory syndrome and subsequently to clinically devastating complications including gastroesophageal varices and variceal hemorrhage, hepatic encephalopathy from the formation of portosystemic shunts, ascites, and renal failure due to the hepatorenal syndrome. This review article discusses: (1) mechanisms of sinusoidal portal hypertension, focusing on HSC and LSEC biology, pathological angiogenesis, and the role of microvascular thrombosis and platelets, (2) the mesenteric vasculature in portal hypertension, and (3) future directions for vascular biology research in portal hypertension.

    The objective of this multicenter cross-sectional study was to investigate the relationship of nocturnal polyuria in patients with common lifestyle related diseases and overactive bladder, with special attention to hypertension. After baseline assessment, patients recorded 24-hour urinary frequency/volume, blood pressure and heart rate for 3 days. They were stratified into 4 groups based on mean blood pressure, including no hypertension, and controllable, untreated and uncontrolled hypertension, respectively. The 2,353 eligible patients, who had urinary urgency once or more per week and 1 or more nocturnal toilet visits, were enrolled from 543 sites in Japan. Of these patients complete data, including the 24-hour frequency volume chart, were collected from 1,271. Multivariable analyses showed a statistically significant association of nocturnal polyuria with increasing age (OR 1.04, 95% CI 1.02-1.05, p polyuria in women alone (p = 0.01 and 0.03, respectively). Lower urinary tract symptoms suggestive of benign prostatic hyperplasia were significantly associated with nocturnal polyuria in men alone (p polyuria was significantly associated with age, male gender, and untreated hypertension in patients with lifestyle related diseases and overactive bladder. The association between hypertension and nocturnal polyuria was significant in women alone. Copyright © 2017 American Urological Association Education and Research, Inc. Published by Elsevier Inc.

    2018-04-24

    The American College of Cardiology (ACC) and the American Heart Association (AHA) have recently published their guidelines for the prevention, detection, evaluation, and management of hypertension in adults. The most controversial issue is the classification threshold at 130/80mmHg, which will allow a large number of patients to be diagnosed as hypertensive who were previously considered normotensive. Blood pressure (BP) is considered normal (<120mmHg systolic and <80mmHg diastolic), elevated (120-129 and <80mmHg), stage 1 (130-139 or 80-89mmHg), and stage 2 (≥140 or ≥90mmHg). Out-of-office BP measurements are recommended to confirm the diagnosis of hypertension and for titration of BP-lowering medication. In management, cardiovascular risk would be determinant since those with grade 1 hypertension and an estimated 10-year risk of atherosclerotic cardiovascular disease ≥10%, and those with cardiovascular disease, chronic kidney disease and/or diabetes will require pharmacological treatment, the rest being susceptible to non-pharmacological treatment up to the 140/90mmHg threshold. These recommendations would allow patients with level 1 hypertension and high atherosclerotic cardiovascular disease to benefit from pharmacological therapies and all patients could also benefit from improved non-pharmacological therapies. However, this approach should be cautious because inadequate BP measurement and/or lack of systematic atherosclerotic cardiovascular disease calculation could lead to overestimation in diagnosing hypertension and to overtreatment. Guidelines are recommendations, not impositions, and the management of hypertension should be individualized, based on clinical decisions, preferences of the patients, and an adequate balance between benefits and risks.

    2012-06-01

    The Millennium Genome Project for Hypertension was started in 2000 to identify genetic variants conferring susceptibility to hypertension, with the aim of furthering the understanding of the pathogenesis of this condition and realizing genome-based personalized medical care. Two different approaches were launched, genome-wide association analysis using single-nucleotide polymorphisms (SNPs) and microsatellite markers, and systematic candidate gene analysis, under the hypothesis that common variants have an important role in the etiology of common diseases. These multilateral approaches identified ATP2B1 as a gene responsible for hypertension in not only Japanese but also Caucasians. The high blood pressure susceptibility conferred by certain alleles of ATP2B1 has been widely replicated in various populations. Ex vivo mRNA expression analysis in umbilical artery smooth muscle cells indicated that reduced expression of this gene associated with the risk allele may be an underlying mechanism relating the ATP2B1 variant to hypertension. However, the effect size of a SNP was too small to clarify the entire picture of the genetic basis of hypertension. Further, dense genome analysis with accurate phenotype data may be required.

    Full Text Available Objective: The objective of this paper was to propose an algorithm for approaching hypertensive hemodialysis patients admitted to the hospital for hypertensive urgency. Methods: A literature search was conducted using PubMed (Medline. Articles selected were limited to humans and the English language. Results: We identified eight management modalities including: short-daily and nocturnal dialysis, sodium restriction, sodium profiling, antihypertensive medications, sympathetic denervation, bilateral nephrectomy, and bioimpedance spectroscopy. The benefits and drawbacks of each were investigated and discussed before implementation into the algorithm. Discussion: The algorithm presented suggests a linear approach to patient care, but treatment modalities may not be mutually exclusive, and additional factors, such as patient compliance and individual health status, should be taken into account to provide patients with optimum care.

    Urinary incontinence (UI) is common and the relationship among its subtypes complex. Our objective was to describe the natural history and predictors of the incontinence subtypes stress, urgency, and mixed, in middle-aged and older US women. We tested our hypothesis that UI subtype history predicted future occurrence, evaluating subtype incidence/remission over multiple time points in a stable cohort of women. We analyzed longitudinal urinary incontinence data in 10,572 community-dwelling women aged ≥50 in the 2004-2010 Health and Retirement Study. Mixed, stress, and urgency incontinence prevalence (2004, 2006, 2008, 2010) and 2-year cumulative incidence and remissions (2004-2006, 2006-2008, 2008-2010) were estimated. Patient characteristics and incontinence subtype status 2004-2008 were entered into a multivariable, transition model to determine predictors for incontinence subtype occurrence in 2010. The prevalence of each subtype in this population (median age 63-66) was 2.6-8.9 %. Subtype incidence equaled 2.1-3.5 % and remissions for each varied between 22.3 and 48.7 %. Incontinence subtype incidence predictors included ethnicity/race, age, body mass index, and functional limitations. Compared with white women, black women had decreased odds of incident stress incontinence and Hispanic women had increased odds of stress incontinence remission. The age range 80-90 and severe obesity predicted incident mixed incontinence. Functional limitations predicted mixed and urgency incontinence. The strongest predictor of incontinence subtype was subtype history. The presence of the respective incontinence subtypes in 2004 and 2006 strongly predicted 2010 recurrence (odds ratio [OR] stress incontinence = 30.7, urgency OR = 47.4, mixed OR = 42.1). Although the number of remissions was high, a previous history of incontinence subtypes predicted recurrence. Incontinence status is dynamic, but tends to recur over the longer term.

    ão controlada. Este conhecimento deve ser rotineiro ao emergencista e Intensivista no momento de decidir sobre a conduta.Emergencies and hypertensive crises are clinical situations which may represent more than 25% of all medical emergency care. Considering such high prevalence, physicians should be prepared to correctly identify these crises and differentiate between urgent and emergent hypertension. Approximately 3% of all visits to emergency rooms are due to significant elevation of blood pressure. Across the spectrum of blood systemic arterial pressure, hypertensive emergency is the most critical clinical situation, thus requiring special attention and care. Such patients present with high blood pressure and signs of acute specific target organ damage (such as acute myocardial infarction, unstable angina, acute pulmonary edema, eclampsia, and stroke. Key elements of diagnosis and specific treatment for the different presentations of hypertensive emergency will be reviewed in this article. The MedLine and PubMed databases were searched for pertinent abstracts, using the key words "hypertensive crises" and "hypertensive emergencies". Additional references were obtained from review articles. Available English language clinical trials, retrospective studies and review articles were identified, reviewed and summarized in a simple and practical way. The hypertensive crisis is a clinical situation characterized by acute elevation of blood pressure followed by clinical signs and symptoms. These signs and symptoms may be mild (headache, dizziness, tinnitus or severe (dyspnea, chest pain, coma or death. If the patient presents with mild symptoms, but without acute specific target organ damage, diagnosis is hypertensive urgency. However, if severe signs and symptoms and acute specific target organ damage are present, then the patient is experiencing a hypertensive emergency. Some patients arrive at the emergency rooms with high blood pressure, but without any other sign or symptom. In

    To explore the impact of urgency urinary incontinence (UUI) on well-being in non-institutionalized patients with overactive bladder (OAB) in a community sample. A cross-sectional web-based study was conducted in the general population, including males and females, >18 years of age. Patients with probable OAB were identified using a validated algorithm together with a score ≥8 on the OAB-V8 scale. Presence of coping behavior was considered determinant for the clinical diagnosis of OAB. Individual well-being was determined through a battery of patient-reported outcomes (PRO) measurements including assessment of health-related quality of life (EQ-5D), sleep disturbances (MOS Sleep), and life satisfaction (LISAT-8). Patients were grouped according to the number of daily UUI episodes (UUI severity): 0 (dry OAB),1, 2-3, or ≥4. Multivariate analysis to evaluate factors independently affecting quality of life was undertaken. A total of 396 patients (52.5% women, mean age: 55.3 [11.1] years, OAB-V8 mean score: 14.5 [7.9]) out of 2035 subjects participating from the general population met the criteria for OAB: 203 (51.3%) with 0episodes, 119 (30.1%) with 1, 52 (13.1%) with 2 or 3, and 22 (5.6%) with ≥4 episodes. A statistically significant linear adjusted association was found between number of UUI episodes and PRO scores. Participants with more episodes had poorer health profiles and self-evaluated quality of life, worse life satisfaction, and more sleep disturbances and fewer hours of sleep per night. Number of incontinence episodes was independent factor to affect quality of life using both LISAT-8 and MOS questionnaires. Severity of UUI was significantly associated with poorer individual well-being in subjects with OAB in a community sample in Spain. Copyright © 2015 AEU. Publicado por Elsevier España, S.L.U.

    The Eurotransplant High-Urgency (HU) Heart Transplantation Program allows urgent heart transplants to be carried out in rapidly deteriorating patients with acute-to-chronic heart failure on the elective waiting list. But do the results of HU heart transplantation justify performing primary heart transplantation in these critically ill patients and offer an acceptable outcome? Between 2000 and 2004, 64 heart transplantations (HTx) (32 elective and 32 HU-HTx) were performed in our department. After having been accepted in an auditing process based on HU criteria, intensive care patients in NYHA functional class IV (cardiac index 1.7 l/min/qm BS), in end-organ failure (creatinine 1.5 mg/dl), and with catecholamine dependence (dobutamine 8 microg/kg/min), are given priority with respect to organ allocation, and their data were compared to data from elective patients from the same period. HU requests were accepted in 97 % of cases. Two requests were not accepted, and both patients with contraindications for assist device implantation died within one week. The HU patients were 100 % in NYHA class IV, 93 % of the elective patients were in NYHA class III. Waiting time on the HU list was 13 days, and 7 of these patients died before HTx. Following heart transplantation, survival rates at 30 days and at one year of the HU group were 88 % and 85 % versus 94 % and 93 % in the elective group. This study shows that end-stage heart failure patients in the HU program can be transplanted primarily with good results if an organ is available in time. We are still in the position where the HU program only manages the organ shortage; there are still too many patients on the waiting list who die before receiving a donor organ.

    Even though pregnancy is rare with cirrhosis and advanced liver disease, but it may co-exist in the setting of non-cirrhotic portal hypertension as liver function is preserved but whenever encountered together is a complex clinical dilemma. Pregnancy in a patient with portal hypertension presents a special challenge to the obstetrician as so-called physiological hemodynamic changes associated with pregnancy, needed for meeting demands of the growing fetus, worsen the portal hypertension thereby putting mother at risk of potentially life-threatening complications like variceal hemorrhage. Risks of variceal bleed and hepatic decompensation increase many fold during pregnancy. Optimal management revolves round managing the portal hypertension and its complications. Thus management of such cases requires multi-speciality approach involving obstetricians experienced in dealing with high risk cases, hepatologists, anesthetists and neonatologists. With advancement in medical field, pregnancy is not contra-indicated in these women, as was previously believed. This article focuses on the different aspects of pregnancy with portal hypertension with special emphasis on specific cause wise treatment options to decrease the variceal bleed and hepatic decompensation. Based on extensive review of literature, management from pre-conceptional period to postpartum is outlined in order to have optimal maternal and perinatal outcomes. PMID:25755552

  18. Management of diabetic hypertensives

    2011-01-01

    Hypertension occurs twice as commonly in diabetics than in comparable nondiabetics. Patients with both disorders have a markedly higher risk for premature microvascular and macrovascular complications. Aggressive control of blood pressure (BP) reduces both micro- and macrovascular complications. In diabetic hypertensives, angiotensin converting enzyme inhibitors (ACEIs) are the first line in management of hypertension, and can be replaced by angiotensin II receptor blockers (ARBs) if patients are intolerant of them. Recent studies suggest ARBs to be on par with ACEI in reducing both macro- and microvascular risks. Adding both these agents may have a beneficial effect on proteinuria, but no extra macrovascular risk reduction. Thiazides can also be used as first line drugs, but are better used along with ACEI/ARBs. Beta-blockers [especially if the patient has coronary artery disease] and calcium channel blockers are used as second line add-on drugs. Multidrug regimens are commonly needed in diabetic hypertensives. Achieving the target BP of <130/80 is the priority rather than the drug combination used in order to arrest and prevent the progression of macro- and microvascular complications in diabetic hypertensives.

    Essential hypertension is a "disease of civilization" but has a clear genetic component. From an evolutionary perspective, persistence in the human genome of elements capable of raising blood pressure presupposes their adaptive significance. Recently, two hypotheses that explicitly appeal to selectionist arguments, the "slavery" and "thrifty gene" theories, have been forwarded. We find neither completely successful, and we advance an alternative explanation of the adaptive importance of genes responsible for hypertension. We propose that blood pressure rises during childhood and adolescence to subserve homeostatic needs of the organism. Specifically, we contend that blood pressure is a flexible element in the repertoire of renal homeostatic mechanisms serving to match renal function to growth. The effect of modern diet and lifestyle on human growth stimulates earlier and more vigorous development, straining biologically necessary relationships between renal and general somatic growth and requiring compensation via homeostatic mechanisms preserved during evolution. Prime among such mechanisms is blood pressure, which rises as a compensation to maintain renal function in the face of greater growth. Since virtually all members of acculturated societies share in the modern lifestyle, the demands imposed by accelerated growth and development result in a populational shift to higher blood pressures, with a consequent increase in the prevalence of hypertension. We propose that hypertension is the product of maladaptation of highly genetically conserved mechanisms subserving important biological homeostatic needs. Elucidation of the mechanisms underlying hypertension will require approaches that examine the developmental processes linking growth to blood pressure.

    During fertile life women are usually normo or hypotensive. Hypertension may appear during pregnancy and this represents a peculiar phenomenon increasing nowadays for delay time of pregnancy. Gestational hypertension appears partially similar to hypertension in the context of metabolic syndrome for a similar condition of increased waste circumference. Parity, for the same pathogenesis, has been reported to be associated to peri and postmenopausal hypertension, not confirmed by our study of parous women with transitional non persistent perimenopausal hypertension. Estrogen's deficiency inducing endothelial dysfunction and increased body mass index are the main cause for hypertension in this phase of life. For these reasons lifestyle modification, diet and endothelial active drugs represent the ideal treatment. Antioxidant agents may have a role in prevention and treatment of hypertension. In conclusion, hypertension in women represents a peculiar constellation of different biological and pathogenic factors, which need a specific gender related approach, independent from the male model.

  1. Knowledge and awareness of hypertension among patients with systemic hypertension.

    BACKGROUND: In Nigeria, systemic hypertension is the commonest noncommunicable disease, and public awareness about hypertension and its determinants is poor. This study aims to assess the knowledge and level of awareness of the disease among hypertensive patients attending the medical outpatient clinic of Olabisi Onabanjo University Teaching Hospital (OOUTH). METHODOLOGY: Hypertensive patients who attended the medical outpatient clinic during the one-year study period and gave their consent were recruited into the study. Response to a questionnaire on various aspects of hypertension was analyzed using the STATA for Windows software. RESULTS: There were 254 hypertensive patients, of which 111 were males and 143 were females, giving a male: female ratio of 1:1.3. The mean age (SD) of the patients was 51 years +/- 12.2; 52.4% of the participants were aware that hypertension was the commonest noncommunicable disease in Nigeria. About one in 10 patients (11.4%) was aware that "nil symptom" is the commonest symptom of hypertension, while 37% were not aware that hypertension could cause renal failure. Only about one-third (35.4%) of the patients knew that hypertension should ideally be treated for life, while 58.3% believed that antihypertensive drugs should be used only when there are symptoms. The remaining 6.3% believed that the treatment of hypertension should be for periods ranging from two weeks to five years but not for life. CONCLUSION: This study has demonstrated inadequate knowledge of hypertension in patients with hypertension in our study population. Conscious efforts should be made and time set aside to health educate hypertensive patients. Organization of "hypertensive club or society" could be encouraged. These will reduce dissemination of false or inaccurate information by hypertensive patients to the public and its attendant dangers. PMID:15160976

    Hypertension is a condition characterized by pressure and/or volume overloads and echocardiography is helpful and feasible to understand hemodynamic mechanisms. Echocardiographic information is sometimes critical and susceptible of modifying decision making. In this review, we provide detailed descriptions of the parameters that can be derived from a standard transthoracic echocardiogram, including some more recent techniques. We will also explain how each parameter might have impact in the evaluation of the hypertensive patient and give indications on when to refer patients to echo-labs, which parameters are critical and which ones might be redundant, and how to use the information obtained in the report. Cardiac geometry, LV systolic and diastolic function, LV pump performance, output impedance and left atrial function are parameters that might be altered in arterial hypertension, but not necessarily doctors need the whole information for decision making. The critical measures are provided.

    Hypertension is the most common cardiovascular disorder affecting more males in younger age groups; in the age group of 45-64, it is equally frequent in both genders, it is more common in elderly females. Blood pressure increases more in females around the menopause. Use of hormonal replacement therapy is not associated with an BP increase but, because of increased risk of coronary events, stroke, and thromboembolic events, HRT is not re-commended in CVD prevention. There is a similar decrease in BP by antihypertensive drugs in both genders as well as benefit from antihypertensive treatment. Women report about a double rate of adverse events of antihypertensive drugs. Oral contraception use is associated with a mild BP increase in most women and development of overt hypertension in about 5 %. Pre-eclampsia is associated with increased risk of developing CVD later in life (more frequent development of hypertension, myocardial infarction, and stroke).

    Full Text Available This study examined whether urgency, a disposition to rash action under conditions of strong emotion, moderates associations between internalizing symptoms and alcohol use and related expectancies. Data from the Camden Youth Development Study, a longitudinal, community-based study of early adolescents ( N = 144, mean age at intake = 11.9 years; 65% Hispanic, 30% African-American; 50% male, were used. Self-report questionnaire measures of depressive symptoms, social and generalized anxiety symptoms, urgency, alcohol use, and alcohol expectancies were used. Mixed models were used to examine the effects of internalizing symptoms, urgency, and their interaction on alcohol use and expectancy trajectories over time. Depressive symptoms interacted with urgency such that youth with high levels of both tended to have elevated levels of global positive alcohol expectancies. Social anxiety symptoms interacted with urgency to be associated with increasing levels of social behavior alcohol expectancies such that youth with high levels of both tended to experience particular increases in these expectancies over time. Generalized anxiety was not found to be associated with alcohol-related constructs. Therefore, high levels of urgency combine with depressive and social anxiety symptoms to be associated with particularly increased risk for alcohol expectancies that are associated with later alcohol use and problems, indicating particular risk for youth with these combinations of personality traits and psychopathology symptoms.

    The present study examined the interaction between early life stress and 5-HTT genotypes in predicting two risk factors for suicidal behavior - the brooding subtype of rumination and impulsivity, in the form of negative urgency - over time. Furthermore, we examined early life stress, brooding, and impulsivity as predictors of suicidal ideation over time. Participants with and without a history of early life stress were genotyped for the 5-HTTLPR polymorphism and completed assessments assessing brooding and negative urgency at baseline and 6-month follow up. Early life emotional abuse was associated with negative urgency at follow-up. We found an indirect effect of early life emotional abuse on negative urgency through brooding among individuals with 5-HTT low expressing genotypes but not among individuals with 5-HTT high expressing genotypes. Further, a logistic regression analysis revealed that negative urgency was associated with higher odds (O.R. = 16.2) of reporting suicide ideation (versus no ideation) at follow-up. Our findings suggest that brooding and negative urgency may result from the interaction between early life emotional abuse and 5-HTT low expressing genotypes. Further research is necessary to understand how early life stress interacts with 5-HTT genotypes to confer risk for suicidal behavior through psychological mechanisms. Copyright © 2017 Elsevier B.V.

    Objectives: Traditionally, the urinary tract has been thought to be sterile in the absence of a clinically identifiable infection. However, recent evidence suggests that the urinary tract harbors a variety of bacterial species, known collectively as the urinary microbiome, even when clinical cultures are negative. Whether these bacteria promote urinary health or contribute to urinary tract disease remains unknown. Emerging evidence indicates that a shift in the urinary microbiome may play an important role in urgency urinary incontinence (UUI). The goal of this prospective pilot study was to determine how the urinary microbiome is different between women with and without UUI. We also sought to identify if characteristics of the urinary microbiome are associated with UUI severity. Methods: We collected urine from clinically well-characterized women with UUI (n = 10) and normal bladder function (n = 10) using a transurethral catheter to avoid bacterial contamination from external tissue. To characterize the resident microbial community, we amplified the bacterial 16S rRNA gene by PCR and performed sequencing using Illumina MiSeq. Sequences were processed using the workflow package QIIME. We identified bacteria that had differential relative abundance between UUI and controls using DESeq2 to fit generalized linear models based on the negative binomial distribution. We also identified relationships between the diversity of the urinary microbiome and severity of UUI symptoms with Pearson's correlation coefficient. Results: We successfully extracted and sequenced bacterial DNA from 95% of the urine samples and identified that there is a polymicrobial community in the female bladder in both healthy controls and women with UUI. We found the relative abundance of 14 bacteria significantly differed between control and UUI samples. Furthermore, we established that an increase in UUI symptom severity is associated with a decrease in microbial diversity in women with UUI

  1. Decoding white coat hypertension

    2017-01-01

    There is arguably no less understood or more intriguing problem in hypertension that the “white coat” condition, the standard concept of which is significantly blood pressure reading obtained by medical personnel of authoritative standing than that obtained by more junior and less authoritative personnel and by the patients themselves. Using hospital-initiated ambulatory blood pressure monitoring, the while effect manifests as initial and ending pressure elevations, and, in treated patients, a low daytime profile. The effect is essentially systolic. Pure diastolic white coat hypertension appears to be exceedingly rare. On the basis of the studies, we believe that the white coat phenomenon is a common, periodic, neuro-endocrine reflex conditioned by anticipation of having the blood pressure taken and the fear of what this measurement may indicate concerning future illness. It does not change with time, or with prolonged association with the physician, particularly with advancing years, it may be superimposed upon essential hypertension, and in patients receiving hypertensive medication, blunting of the nighttime dip, which occurs in about half the patients, may be a compensatory mechanisms, rather than an indication of cardiovascular risk. Rather than the blunted dip, the morning surge or the widened pulse pressure, cardiovascular risk appears to be related to elevation of the average night time pressure. PMID:28352632

Preoperative arteriography is indispensible for deciding on the appropriate treatment modality and the specifics of the procedure. Arteriography, therefore, remains the cornerstone in managing renovascular hypertension and renal arterial disease

    The economic aspects of hypertension are critical to modern medicine. The medical, economic, and human costs of untreated and inadequately controlled hypertension are enormous. Hypertension is distributed unequally and with iniquity in different countries and regions of the world. Treatment of hypertension requires an investment over many years to prolong disease-free quality years of life. The high prevalence and high cost of the disease impacts on the microeconomics and macroeconomics of countries and regions. The criteria used for inclusion in clinical guidelines for hypertension impact on the cost and cost/utility of diagnosis or treatment.

    Pulmonary hypertension in the perinatal period can present acutely (persistent pulmonary hypertension of the newborn) or chronically. Clinical and echocardiographic diagnosis of acute pulmonary hypertension is well accepted but there are no broadly validated criteria for echocardiographic diagnosis of pulmonary hypertension later in the clinical course, although there are significant populations of infants with lung disease at risk for this diagnosis. Contributing cardiovascular comorbidities are common in infants with pulmonary hypertension and lung disease. It is not clear who should be treated without confirmation of pulmonary vascular disease by cardiac catheterization, with concurrent evaluation of any contributing cardiovascular comorbidities.

    Hypertension is the main risk factor for cardiovascular diseases and stroke. Blood pressure control is a challenge for healthcare providers and the rate of blood pressure control is not more than 50% worldwide. The present study aimed to determine the effectiveness of a short-term educational program on the level of knowledge, lifestyle changes, and blood pressure control among hypertensive patients. This quasi-experimental study was conducted on the hypertensive patients attending Shiraz Healthy Heart House. In this study, 112 patients were selected via systematic random sampling. The study data were collected using a data gathering form which consisted of baseline characteristics and measurements of blood pressure. Multivariate analyses were used to assess the relationship between education and hypertension. At baseline, the scores of aware, treated, and controlled hypertensive patients were 21%, 20%, and 12%, respectively.

    Polycystic ovary syndrome (PCOS) is associated with multiple cardiovascular risk factors. The aims of this study are to investigate the prevalence of hypertension in a female population with PCOS and to correlate hypertension with her clinical and hormonal profile. it is a transversal study of 79 PCOS patients with mean age of 25 +/- 7 years (range 13-44). PCOS diagnosis is made by Rotterdam consensus criteria's (2003). WHO definition of hypertension is used (BP 140/90 mmHg). Blood pressure is measured three times in each patient. Ovarian echography and biochemical assays (GnRH test, androgens, cholesterol, triglycerides, and oral glucose tolerance test) are made before the 5th day of the menstrual cycle. 12% of PCOS women have hypertension. Family history of hypertension is not a predictive factor of hypertension in our study. PCOS patients with hypertension are not significantly older than those without hypertension (28.4 +/- 6.5 vs. 25.2 +/- 7; p = 0.12). If compared to PCOS women without hypertension, those with hypertension have a significantly higher BMI (39.2 +/- 7 vs. 29.6; p = 0.0004). PCOS patients with and without hypertension do not differ significantly in their level of androgens and total cholesterol. Triglycerides level is higher in PCOS patients with hypertension (p = 0.06). In oral glucose tolerance test, areas under the curve of insulin and glucose are significantly higher in PCOS patients with hypertension (respectively p = 0.06 and 0.02). The area under the curve of LH during GnRH test is lower in PCOS patients with hypertension (p = 0.04).

    Systemic hypertension is an important risk factor for premature cardiovascular disease. Hypertension also contributes to excessive morbidity and mortality. Whereas excellent therapeutic options are available to treat hypertension, there is an unsettled issue about the very definition of hypertension. At what level of blood pressure should we treat hypertension? Does the definition of hypertension change in the presence of co-morbid conditions? This article covers in detail the evolving concepts in the diagnosis and management of hypertension.

    Cardiorespiratory fitness and regular physical activity are inversely associated with the risk of hypertension, and exercise training has been shown to lower elevated blood pressure (BP). Genetic factors contribute significantly to the interindividual differences in endurance training-induced changes in BP. However, similar data on the genotype-by-fitness interactions on the risk of hypertension are scarce. In 2000, we started a systematic collection of blood samples from all consenting subjects of the Aerobics Center Longitudinal Study (ACLS) with a goal to generate a resource for studies addressing genotype-by-fitness interaction effects on various health-related end points. Here, we introduce the rationale and design of the first study based on the ACLS genetics resource focusing on hypertension as the health outcome (HYPGENE study), and we report the associations of cardiorespiratory fitness and body mass index (BMI) with the risk of hypertension. All HYPGENE subjects (N = 1234) were healthy and normotensive at their first clinic visit. Cases (N = 629) developed hypertension during the follow-up period (mean 8.7 yr), whereas controls (N = 605) remained normotensive (mean follow-up 10.1 yr). Cardiorespiratory fitness was the strongest predictor of the hypertension risk, with each maximal metabolic equivalent unit being associated with a 19% lower risk (95% confidence interval [95% CI], 12-24%). Each baseline BMI unit was associated with a 9% higher hypertension risk (95% CI, 4-13%). However, the association of BMI was greatly attenuated (odds ratio 1.04 [95% CI, 0.99-1.09]) when fitness also was included in the model. The HYPGENE study will provide an excellent resource to address hypotheses regarding the genetic basis of hypertension while taking cardiorespiratory fitness level into account.

While there is strong evidence for its role in maintaining bone and muscle health, there has been recent debate regarding the role of vitamin D deficiency in hypertension based on conflicting epidemiological evidence. Thus, we conducted a scoping systematic literature review and meta-analysis of all observational studies published up to early 2014 in order to map trends in the evidence of this association. Mixed-effect meta-analysis was performed to pool risk estimates from ten prospective studies (n=58,262 (pooled risk for incident hypertension, relative risk [RR] =0.76 (0.63–0.90 for top vs bottom category of 25-hydroxyvitamin D [25OHD] and from 19 cross-sectional studies (n=90,535 (odds ratio [OR] =0.79 (0.73–0.87. Findings suggest that the better the assessed quality of the respective study design, the stronger the relationship between higher 25OHD levels and hypertension risk (RR =0.67 (0.51–0.88; OR =0.77 (0.72–0.89. There was significant heterogeneity among the findings for both prospective and cross-sectional studies, but no evidence of publication bias was shown. There was no increased risk of hypertension when the participants were of older age or when they were vitamin D deficient. Younger females showed strong associations between high 25OHD levels and hypertension risk, especially in prospective studies (RR =0.36 (0.18–0.72; OR =0.62 (0.44–0.87. Despite the accumulating evidence of a consistent link between vitamin D and blood pressure, these data are observational, so questions still remain in relation to the causality of this

  19. Hepatic angiography: Portal hypertension

    Portal hypertension is usually a manifestation of underlying hepatic parenchymal disease, although it may be secondary to portal or hepatic venous thrombosis and rarely to hyperdynamic portal states. Portal hypertension may present as encephalopathy, ascites, jaundice, hepatic failure, or catastrophic upper gastrointestinal hemorrhage. Radiologic investigation should include indirect or direct measurements of portal pressure, assessment of portal venous perfusion, visualization of collaterals, and demonstration of arterial and venous anatomy for potential shunt procedure. Following survival of initial variceal bleeding, the most effective procedure to prevent recurrent hemorrhage is a shunt to decompress the varices. The decision whether to intervene medically or surgically during the acute hemorrhagic episode as well as the type of shunt used to prevent future hemorrhage is the subject of continuing controversy

    Regular endurance training has established itself as a major therapeutic principle in the specter of nonpharmacological measures in arterial hypertension. An initial medical check as well as an adequate technique, dosage and intensity of the prescribed exercise training are mandatory. With respect to the concomitant pharmacological treatment, it should be considered that the beneficial effects of lifestyle modification will not be counteracted by the chosen antihypertensive drug but, ideally, synergistically supported. Based on the individual clinical situation, principally all antihypertensive drugs recommended by the current European guidelines, may be prescribed as mono- or combination therapy.beta-receptor blockers are especially capable of controlling excessive exercise-induced blood pressure increase; however, they have metabolic and exercise physiological limitations. The neutrality concerning metabolic and exercise physiological parameters as well as the positive profile of side effects favor ACE inhibitors, long-acting calcium channel blockers and especially AT(1) antagonists in physically active hypertensive patients with concomitant metabolic syndrome.

    Hypertensive disorders in pregnancy are a leading cause of maternal and perinatal mortality and morbidity. The management of patients with chronic hypertension requires a multidisciplinary approach prior to conception, during pregnancy and post-partum. In the preconception period, fetotoxic agents should be discontinued. It is also essential to undertake a full cardiovascular examination which may, in some cases, question the possibility of pregnancy. During pregnancy, blood pressure should be monitored and controlled, but not necessarily returned to a normal value. Low blood pressure levels could indeed lead to placental hypoperfusion and fetal growth restriction. Close clinical, biological and ultrasound monitoring is recommended, even postpartum, since those patients are at higher risk for preeclampsia.

  2. Adrenal Mass Causing Secondary Hypertension.

    Robinson, Darlene Y

    2015-11-01

    Most hypertensive patients have essential (primary) hypertension; only 5% to 10% have a secondary cause. Two clinical characteristics suggestive of secondary hypertension are early onset (hypertension (>180/110 mm Hg). When faced with these findings, clinicians should consider a secondary cause of hypertension. A 22-year-old woman being evaluated for asthma exacerbation in the emergency department was noted to have severe persistent hypertension. Additional evaluation revealed severe hypokalemia, metabolic alkalosis, and hypernatremia. The patient was admitted to the hospital for blood pressure management, electrolyte replacement, and further evaluation of presumed hyperaldosteronism. Diagnostic imaging revealed a large adrenal mass. Surgical resection was performed, leading to a diagnosis of hyperaldosteronism caused by adrenal carcinoma. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: Secondary hypertension is far less common than essential hypertension; however, considering the large volume of patients seen in emergency departments, it is likely that some will have secondary hypertension. Emergency physicians should be aware of the clinical characteristics that suggest secondary hypertension so that the appropriate diagnostic and treatment pathways can be pursued.

  3. Neurological disorders in hypertensive patients

    Full Text Available Hypertension is one of the most common vascular diseases. The brain as target organs in hypertension is damaged more often and earlier. Neurological complications due to hypertension are frequently hyperdiagnosed in Russian neurological practice. Thus, headache, dizziness, impaired recall of recent events, nocturnal sleep disorders, and many other complaints in a hypertensive patient are usually regarded as a manifestation of dyscirculatory encephalopathy. At the same time headaches (tension headache and migraine in hypertensive patients are predominantly primary; headache associated with dramatic marked elevations in blood pressure is encountered in only a small number of patients. The role of cerebrovascular diseases in the development of dizziness in hypertensive patients is also overestimated. The vast majority of cases, patients with this complaint are in fact identified to have benign paroxysmal postural vertigo, Mеniеre’s disease, vestibular neuronitis, or vestibular migraine. Psychogenic disorders or multisensory insufficiency are generally responsible for non-systemic vertigo in hypertensive patients. Chronic cerebral circulatory insufficiency may cause non-systemic vertigo as a subjective equivalent of postural instability.Cognitive impairments (CIs are the most common and earliest manifestation of cerebrovascular lesion in hypertension. In most cases, CIs in hypertension were vascular and associated with cerebrovascular lesion due to lacunar infarcts and leukoaraiosis. However, mixed CIs frequently occur when hypertensive patients are also found to have signs of a degenerative disease, most commonly in Alzheimer’s disease.

    2011-01-01

    The prevalence of hypertension, chronic kidney disease (CKD) and end-stage renal disease (ESRD) attributable to hypertension continues to rise worldwide. Identifying the precise prevalence of CKD attributable to hypertension is difficult owing to the absence of uniform criteria to establish a diagnosis of hypertensive nephropathy. Despite the increasing prevalence of CKD-associated hypertension, awareness of hypertension among individuals with CKD remains suboptimal and rates of blood-pressure control remain poor. Targeted subgroups involved in studies of CKD seem to reach better rates of blood-pressure control, suggesting that this therapeutic goal can be achieved in patients with CKD. Elevated blood-pressure levels are associated with CKD progression. However, the optimal blood-pressure level and pharmacological agent remains unclear. Physicians treating patients with CKD must recognize the importance of maintaining optimal salt and volume balance to achieve blood-pressure goals. Furthermore, agents that modify the renin-angiotensin-aldosterone axis can be an important adjunct to therapy and physicians must monitor expected changes in serum creatinine and electrolyte levels after their administration. Hypertension remains a common factor complicating CKD. Future investigations identifying early signs of hypertension-related CKD, increasing awareness of the effects of hypertension in CKD and determining optimal therapeutic interventions might help reduce the incidence of hypertensive nephropathy.

    We report on the cooperative possibilities the radiologist has as to diagnosis and therapy of portal hypertension. The catheter angiography allows to make a differentiation between pre- and intrahepatic bloc and the localization of bleeding esophagus varices. Only after all endoscopic measures with sclerotherapy and Laser coagulation have failed, catheter angiography will be carried out as a therapeutic measure. The future development, however, will give the opportunity to a series of therapeutic attempts on the field of interventional radiology.

    2011-06-01

    Essential hypertension remains one of the biggest challenges in medicine with an enormous impact on both individual and society levels. With the exception of relatively rare monogenetic forms of hypertension, there is now general agreement that the condition is multifactorial in nature and hence requires therapeutic approaches targeting several aspects of the underlying pathophysiology. Accordingly, all major guidelines promote a combination of lifestyle interventions and combination pharmacotherapy to reach target blood pressure (BP) levels in order to reduce overall cardiovascular risk in affected patients. Although this approach works for many, it fails in a considerable number of patients for various reasons including drug-intolerance, noncompliance, physician inertia, and others, leaving them at unacceptably high cardiovascular risk. The quest for additional therapeutic approaches to safely and effectively manage hypertension continues and expands to the reappraisal of older concepts such as renal denervation. Based on the robust preclinical and clinical data surrounding the role of renal sympathetic nerves in various aspects of BP control very recent efforts have led to the development of a novel catheter-based approach using radiofrequency (RF) energy to selectively target and disrupt the renal nerves. The available evidence from the limited number of uncontrolled hypertensive patients in whom renal denervation has been performed are auspicious and indicate that the procedure has a favorable safety profile and is associated with a substantial and presumably sustained BP reduction. Although promising, a myriad of questions are far from being conclusively answered and require our concerted research efforts to explore the full potential and possible risks of this approach. Here we briefly review the science surrounding renal denervation, summarize the current data on safety and efficacy of renal nerve ablation, and discuss some of the open questions that need

    To assess the efficacy of pelvic floor physical therapy (PFPT) as primary treatment of urinary urgency and frequency symptoms We conducted a prospective cohort study of women with urinary urgency and frequency symptoms. Participants underwent PFPT once or twice per week for 10 weeks. Symptom improvement was assessed by validated questionnaires (Pelvic Floor Distress Inventory-Short Form 20 and Patient Global Impression of Improvement), voiding diaries, and subjective measures. Fifty-seven participants enrolled; 21 (36.8%) withdrew or completed less than 5 weeks of PFPT. Thirty-one (54.4%) of the remaining 36 participants completed 10 weeks of PFPT. The mean age of the study group (n = 36) was 48.9 ± 15.0 years. The primary diagnoses were overactive bladder syndrome (n = 24, 66.7%) and painful bladder syndrome (n = 12, 33.3%). Women attended a median of 14.0 (interquartile range [IQR], 8.0-16.0) PFPT visits over a median of 11.9 weeks (IQR, 10.0-18.1). At baseline, the median Pelvic Floor Distress Inventory-Short Form 20 score was 79.2 (IQR, 53.1-122.9), and decreased to 50.0 (IQR, 25.0-88.5; P therapies. The high dropout rates suggest that motivation or logistic factors may play a significant role in the utilization and success of this treatment option.

    2015-06-01

    Some polyphenols, obtained from plants of broad use, induce a favorable endothelial response in hypertension and beneficial effects in the management of other metabolic cardiovascular risks. Previous studies in our laboratories using the calyces of Hibiscus sabdariffa as a source of polyphenols show that significant effects on hypertension are noticeable in humans only when provided in high amounts. Available data are suggestive in animal models and ex vivo experiments, but data in humans are difficult to acquire. Additionally, and despite the low bioavailability of polyphenols, intervention studies provide evidence for the protective effects of secondary plant metabolites. Assumptions on public health benefits are limited by the lack of scientific knowledge, robust data derived from large randomized clinical trials, and an accurate assessment of the bioactive components provided by common foodstuff. Because it is likely that clinical effects are the result of multiple interactions among different polyphenols rather than the isolated action of unique compounds, to provide polyphenol-rich botanical extracts as dietary supplements is a suggestive option. Unfortunately, the lack of patent perspectives for the pharmaceutical industries and the high cost of production and release for alimentary industries will hamper the performance of the necessary clinical trials. Here we briefly discuss whether and how such limitations may complicate the extensive use of plant-derived products in the management of hypertension and which steps are the necessary to deal with the predictable complexity in a possible clinical practice.

    An estimated 10% to 20% of hypertensive patients could be considered resistant to treatment (RH). These are patients who are not controlled using three drugs, at the maximum tolerated doses, including a diuretic, as well as those with high blood pressure controlled using four or more drugs. The term is used to identify patients that might benefit from special diagnostic and/or therapeutic consideration. The term 'refractory hypertension' has recently been proposed as a novel phenotype of antihypertensive failure. It refers to patients whose blood pressure cannot be controlled with maximum treatment. The first studies of this phenotype indicate that it is rare and affects less than 5% of patients with RH. Adherence to or compliance with medical treatment is key to defining resistant hypertension. Closer attention has been paid to clinical and experimental research since the first scientific statement for the diagnosis, assessment and treatment of RH from the American Heart Association, and in the European guidelines, was published in 2008. This review will set out the concepts relating to prevalence, prognosis and compliance and cover the latest developments on this subject. Copyright © 2018 SEH-LELHA.

    Hahn, Austin M; Tirabassi, Christine K; Simons, Raluca M; Simons, Jeffrey S

    2015-11-01

    This study tested a path model of relationships between military sexual trauma (MST), combat exposure, negative urgency, posttraumatic stress disorder (PTSD) symptoms, and alcohol use and related problems. The sample consisted of 86 Operation Enduring Freedom/Operation Iraqi Freedom (OEF/OIF) veterans who reported drinking at least one alcoholic beverage per week. PTSD mediated the relationships between MST and alcohol-related problems, negative urgency and alcohol-related problems, and combat exposure and alcohol-related problems. In addition, negative urgency had a direct effect on alcohol problems. These results indicate that MST, combat exposure, and negative urgency independently predict PTSD symptoms and PTSD symptoms mediate their relationship with alcohol-related problems. Findings support previous literature on the effect of combat exposure and negative urgency on PTSD and subsequent alcohol-related problems. The current study also contributes to the limited research regarding the relationship between MST, PSTD, and alcohol use and related problems. Clinical interventions aimed at reducing emotional dysregulation and posttraumatic stress symptomology may subsequently improve alcohol-related outcomes. (c) 2015 APA, all rights reserved).

    Full Text Available Low levels of detection, treatment and control of hypertension have repeatedly been reported from sub Saharan Africa, potentially increasing the likelihood of target organ damage.A cross-sectional study was conducted on 1015 urban civil servants aged > or = 25 years from seven central government ministries in Accra, Ghana. Participants diagnosed to have hypertension were examined for target organ involvement. Hypertensive target organ damage was defined as the detection of any of the following: left ventricular hypertrophy diagnosed by electrocardiogram, reduction in glomerular filtration rate, the presence of hypertensive retinopathy or a history of a stroke.Of the 219 hypertensive participants examined, 104 (47.5% had evidence of target organ damage. The presence of target organ damage was associated with higher systolic and diastolic blood pressure levels. The odds of developing hypertensive target organ damage was five to six times higher in participants with blood pressure (BP > or = 180/110 mmHg compared to those with BP < 140/90 mmHg, and there was a trend to higher odds of target organ damage with increasing BP (p = 0.001. Women had about lower odds of developing target organ damage compared to men.The high prevalence of target organ damage in this working population associated with increasing blood pressure, emphasises the need for hypertension control programs aimed at improving the detection of hypertension, and importantly addressing the issues inhibiting the effective treatment and control of people with hypertension in the population.

    In a cross sectional study we determined prevalence of hypertension among institutionalized old subjects. Prevalence of hypertension was 69%. Among detected hypertensive patients, 76% received an antihypertensive drug treatment. 61% of the declared hypertensive patients and 80% of the treated hypertensive patients had their blood pressure controlled. The general practitioners should better detect and treat this common geriatric problem associated with a high comorbidity.

    Hepatopulmonary syndrome (HPS) and portopulmonary hypertension (POPH) are two frequent pulmonary complications of liver disease. Portal hypertension is a key element in the pathogenesis of both disorders, which are however distinct in terms of pathogenesis, diagnosis and treatment. HPS corresponds to an abnormal arterial oxygenation in relation with the development of intrapulmonary vascular dilatations. POPH is a pulmonary arterial hypertension in the setting of portal hypertension and elevated pulmonary vascular resistance. As both diseases are associated with an increased risk of morbidity and mortality, it is important to screen and evaluate the severity of these two disorders particularly in liver transplant candidates.

  20. Vascular inflammatory cells in hypertension

    Full Text Available Hypertension is a common disorder with uncertain etiology. In the last several years, it has become evident that components of both the innate and adaptive immune system play an essential role in hypertension. Macrophages and T cells accumulate in the perivascular fat, the heart and the kidney of hypertensive patients and in animals with experimental hypertension. Various immunosuppressive agents lower blood pressure and prevent end-organ damage. Mice lacking lymphocytes are protected against hypertension, and adoptive transfer of T cells, but not B cells in the animals restores their blood pressure response to stimuli such as angiotensin II or high salt. Recent studies have shown that mice lacking macrophages have blunted hypertension in response to angiotensin II and that genetic deletion of macrophages markedly reduces experimental hypertension. Dendritic cells have also been implicated in this disease. Many hypertensive stimuli have triggering effects on the central nervous system and signals arising from the circumventricular organ seem to promote inflammation. Studies have suggested that central signals activate macrophages and T cells, which home to the kidney and vasculature and release cytokines, including IL-6 and IL-17, which in turn cause renal and vascular dysfunction and lead to blood pressure elevation. These recent discoveries provide a new understanding of hypertension and provide novel therapeutic opportunities for treatment of this serious disease.

    Full Text Available Introduction: The otologic symptoms associated with hypertension are discussed for decades, yet its etiology remains obscure. Objective: To compare the frequency of vertigo in elderly patients with and without hypertension. Method:A prospective study of 238 individuals. We administered a questionnaire to fill in systematic data for verification of hypertension and vertigo-based protocol for audiological anamnesis used in routine care. Results and Discussion: There were a higher proportion of women in both groups. As for age, mean age was similar between the groups between the two groups. Regarding the use of medication, all were using some kind of medication continuously. In the study population with hypertension, 106 (90% were using antihypertensive drugs. From 99 individuals who reported dizziness 22 (15.15% of seniors were using anti-vertigo. Hypertensive patients 58 (23.8% subjects reported dizziness and 41 non-hypertensive (16% subjects reported dizziness. There was no significance between vertigo and hypertension in the study group, this probably by some criteria as to exclude individuals with diseases and use of medications capable of producing dizziness, which could not be avoided during the implementation, since most of them had associated disorders, common in the elderly. Conclusion: It was observed in the elderly with and without hypertension, high frequency of vertigo, although we have not achieved significant relationship between vertigo and hypertension in this population.

    Emotional and behavioral regulation has been linked to coping and enhancement motives and associated with different patterns of alcohol use and problems. The current studies examined emotional instability, urgency, and internal drinking motives as predictors of alcohol dependence symptoms as well as the likelihood and severity of Diagnostic and Statistical Manual of Mental Disorders-5th editionAlcohol Use Disorder (AUD). In Study 1, college drinkers (n = 621) completed alcohol involvement and behavioral/emotional functioning assessments. There was an indirect association between emotional instability and dependence symptoms via both coping and enhancement drinking motives which was potentiated by trait urgency. In Study 2, college drinkers (n = 510) completed alcohol involvement, behavioral/emotional functioning, and AUD criteria assessments. A significant indirect effect from emotional instability to the likelihood of meeting AUD criteria, via drinking to cope was found, again potentiated by urgency. © The Author(s) 2016.

    Boban Milojković

    2014-12-01

    Full Text Available Arterial hypertension is a major risk factor that predisposes to cardiovascular disorders and is responsible for most of the morbidity and mortality in patients. Hypertension is closely associated with the kidney, because kidney disease can be both the cause and consequence of increased blood pressure. Elevation of blood pressure is a strong independent risk factor for hypertensive nephropathy and development of ESRD. The pathogenesis of ischemic hypertensive nephropathy (IHN is multifactoral, and in addition to blood pressure other factors contribute to the development of this renal pathology and its progression to end-stage renal disease. These include obesity, smoking, male gender and other still unknown risk factors. The aim of this paper was to analyse the association between essential arterial hypertension and renal hypertensive disease and prevalence of other atherosclerotic risk factors in patients with developed hypertensive renal disease. In this prospective cross sectional study 283 patients of both genders with diagnosed essential hypertension and hypertensive renal disease were analysed. The anamnestic data related to age, duration of hypertension, history of smoking, presence of hypertensive retinopathy, hypertrophy of the left chamber and data about previous renal diseases were collected through conversation and medical documentation. The clinical examination comprise determination of blood pressure, body mass index (BMI, lipid parameters (total cholesterol, LDL cholesterol, HDL cholesterol and triglycerides, serum urea and creatinine, urine, albumin and protein concentration. The total number of 283 patients (185 males and 98 females with HN was analyzed. The analysis revealed significantly higher proportion of males aged over 60 years with IHN. The mean age of examined hypertensive patients with IHN is 62.6±8.8 years with duration of hypertension 19.8±5.9 years. All examined patients had hypertensive retinopathy and

    2009-01-01

    Full Text Available Abstract Background Prioritization of waiting lists for elective surgery represents a major issue in public systems in view of the fact that patients often suffer from consequences of long waiting times. In addition, administrative and standardized data on waiting lists are generally lacking in Italy, where no detailed national reports are available. This is true although since 2002 the National Government has defined implicit Urgency-Related Groups (URGs associated with Maximum Time Before Treatment (MTBT, similar to the Australian classification. The aim of this paper is to propose a model to manage waiting lists and prioritize admissions to elective surgery. Methods In 2001, the Italian Ministry of Health funded the Surgical Waiting List Info System (SWALIS project, with the aim of experimenting solutions for managing elective surgery waiting lists. The project was split into two phases. In the first project phase, ten surgical units in the largest hospital of the Liguria Region were involved in the design of a pre-admission process model. The model was embedded in a Web based software, adopting Italian URGs with minor modifications. The SWALIS pre-admission process was based on the following steps: 1 urgency assessment into URGs; 2 correspondent assignment of a pre-set MTBT; 3 real time prioritization of every referral on the list, according to urgency and waiting time. In the second project phase a prospective descriptive study was performed, when a single general surgery unit was selected as the deployment and test bed, managing all registrations from March 2004 to March 2007 (1809 ordinary and 597 day cases. From August 2005, once the SWALIS model had been modified, waiting lists were monitored and analyzed, measuring the impact of the model by a set of performance indexes (average waiting time, length of the waiting list and Appropriate Performance Index (API. Results The SWALIS pre-admission model was used for all registrations in the

    Acute exposure of part of the skin to cold stimuli can evoke urinary urgency, a phenomenon termed acute cold-induced urgency (ACIU). Despite its high prevalence, particularly in patients with overactive bladder, little is known about the mechanisms that induce ACIU. To develop an animal model of ACIU and test the involvement of cold-activated ion channels transient receptor potential (TRP) M8 and TRPA1. Intravesical pressure and micturition were monitored in female mice (wild-type C57BL/6J, Trpa1(-/-), Trpm8(+/+), and Trpm8(-/-)) and Sprague Dawley rats. An intravesical catheter was implanted. Localized cooling of the skin was achieved using a stream of air or topical acetone. The TRPM8 antagonist (N-(3-aminopropyl)-2-{[(3-methylphenyl) methyl]oxy}-N-(2-thienylmethyl)benzamide (AMTB) or vehicle was injected intraperitoneally. Frequencies of bladder contractions and voids in response to sensory stimuli were compared using the Mann-Whitney or Kruskal-Wallis test. Brief, innocuously cold stimuli applied to different parts of the skin evoked rapid bladder contractions and voids in anesthetized mice and rats. These responses were strongly attenuated in Trpm8(-/-) mice and in rats treated with AMTB. As rodent bladder physiology differs from that of humans, it is difficult to directly extrapolate our findings to human patients. Our findings indicate that ACIU is an evolutionarily conserved reflex rather than subconscious conditioning, and provide a useful in vivo model for further investigation of the underlying mechanisms. Pharmacological inhibition of TRPM8 may be useful for treating ACIU symptoms in patients. Brief cold stimuli applied to the skin can evoke a sudden desire to urinate, which can be highly bothersome in patients with overactive bladder. We developed an animal model to study this phenomenon, and found that it depends on a specific molecular cold sensor, transient receptor potential M8 (TRPM8). Pharmacological inhibition of TRPM8 may alleviate acute cold

    Most patients with hypertension have essential hypertension or well-known forms of secondary hypertension, such as renal disease, renal artery stenosis, or common endocrine diseases (hyperaldosteronism or pheochromocytoma). Physicians are less aware of drug induced hypertension. A variety of therapeutic agents or chemical substances may increase blood pressure. When a patient with well controlled hypertension is presented with acute blood pressure elevation, use of drug or chemical substance which increases blood pressure should be suspected. Drug-induced blood pressure increases are usually minor and short-lived, although rare hypertensive emergencies associated with use of certain drugs have been reported. Careful evaluation of prescription and non-prescription medications is crucial in the evaluation of the hypertensive individual and may obviate the need for expensive and unnecessary evaluations. Discontinuation of the offending agent will usually achieve adequate blood pressure control. When use of a chemical agent which increases blood pressure is mandatory, anti-hypertensive therapy may facilitate continued use of this agent. We summarize the therapeutic agents or chemical substances that elevate blood pressure and their mechanisms of action. Copyright © 2015 Elsevier B.V. All rights reserved.

  3. Resistant Hypertension and Cardiorenovascular Risk

    2017-06-01

    Full Text Available Studies have documented independent contribution of sympathetic activation to the cardiovascular disease continuum. Hypertension is one of the leading modifiable factors. Most if not all the benefit of antihypertensive treatment depends on blood pressure lowering, regardless how it is obtained. Resistant hypertension is defined as blood pressure that remains uncontrolled in spite of the concurrent use of three antihypertensive drugs of different classes. Ideally, one of the three drugs should be a diuretic, and all drugs should be prescribed at optimal dose amounts. Poor adherence to antihypertensive therapy, undiscovered secondary causes (e.g. obstructive sleep apnea, primary aldosteronism, renal artery stenosis, and lifestyle factors (e.g. obesity, excessive sodium intake, heavy alcohol intake, various drug interactions are the most common causes of resistant hypertension. Cardio(renovascular morbidity and mortality are significantly higher in resistant hypertensive than in general hypertensive population, as such patients are typically presented with a long-standing history of poorly controlled hypertension. Early diagnosis and treatment is needed to avoid further end-organ damage to prevent cardiorenovascular remodeling. Treatment strategy includes lifestyle changes, adding a mineralocorticoid receptor antagonist, treatment adherence in cardiovascular prevention and, in case of failure to control blood pressure, renal sympathetic denervation or baroreceptor activation therapy. The comparative outcomes in resistant hypertension deserve better understanding. In this review, the most current approaches to resistant hypertension and cardiovascular risk based on the available literature evidence will be discussed.

    Hypertension is an important cause of both maternal and fetal morbidity and mortality in pregnant women. There are still no definitive guidelines as to when and how patients should be treated, but it is important that appropriate treatment is initiated early in patients at highest risk and they are closely monitored. Hypertension in pregnancy can be a difficult condition to diagnose and treat because of the numerous and differing classification systems that have been used in the past. One classification system, which accounts for the multisystem involvement which can occur in pre-eclampsia and eclampsia, divides hypertension in pregnancy into 3 main groups: pre-eclampsia, gestational hypertension and chronic hypertension. Little benefit to the fetus has been shown from treating gestational and chronic hypertension, but studies in this area have been small and would not have had the power to show a difference in outcome between treated and untreated groups. However, the reduction in morbidity and mortality in the treatment of pre-eclampsia is significant. Therefore, all pregnancies complicated by hypertension require monitoring to detect the possible onset of superimposed pre-eclampsia/eclampsia. Institutions should have a management strategy for those mothers with severe hypertension including a multidisciplinary approach, where the patient is to be monitored and which antihypertensive agents are to be used. It should not be forgotten that the definitive treatment for severe hypertension is delivery of the fetus despite risks to fetal morbidity and mortality. This will reduce blood pressure, but hypertension per se may still persist post partum requiring short term therapy.

  9. Beta-Adrenergic Receptor Blockers in Hypertension: Alive and Well.

    Science.gov (United States)

    Frishman, William H

    Beta-adrenergic receptor blockers (β-blockers) are an appropriate treatment for patients having systemic hypertension (HTN) who have concomitant ischemic heart disease (IHD), heart failure, obstructive cardiomyopathy, aortic dissection or certain cardiac arrhythmias. β-Blockers can be used in combination with other antiHTN drugs to achieve maximal blood pressure control. Labetalol can be used in HTN emergencies and urgencies. β-Blockers may be useful in HTN patients having a hyperkinetic circulation (palpitations, tachycardia, HTN, and anxiety), migraine headache, and essential tremor. β-Blockers are highly heterogeneous with respect to various pharmacologic properties: degree of intrinsic sympathomimetic activity, membrane stabilizing activity, β 1 selectivity, α 1 -adrenergic blocking effects, tissue solubility, routes of systemic elimination, potencies and duration of action, and specific properties may be important in the selection of a drug for clinical use. β-Blocker usage to reduce perioperative myocardial ischemia and cardiovascular (CV) complications may not benefit as many patients as was once hoped, and may actually cause harm in some individuals. Currently the best evidence supports perioperative β-blocker use in two patient groups: patients undergoing vascular surgery with known IHD or multiple risk factors for it, and for those patients already receiving β-blockers for known CV conditions.

    Research suggests that negative affect, negative urgency, and thought suppression are related to bulimic symptoms, either directly or indirectly. This study examined associations between these constructs in a sample at-risk for bulimic symptoms. Participants (N = 80) recruited from a residential substance abuse treatment facility completed self-report questionnaires. A regression-based bootstrapping approach was used to examine the indirect effect of negative affect on bulimic symptoms through negative urgency and the moderating role of thought suppression in the association between negative affect and negative urgency. Results revealed a significant indirect effect, significant moderation, and a significant moderated mediation effect, with an indirect effect of negative affect on bulimic symptoms through negative urgency, conditional upon low to moderate (but not high) levels of thought suppression. These findings suggest that negative affect may promote rash actions, particularly in the context of low to moderate thought suppression, leading to increased risk of bulimic symptoms.

    The mechanism of sacral neuromodulation is poorly understood. We compared brain activity during urgency before and after sacral neuromodulation in women with overactive bladder and according to response to treatment. Women with refractory overactive bladder who elected for sacral neuromodulation were invited to undergo a functional magnetic resonance imaging exam before and after treatment. During the imaging exams, the bladder was filled until urgency was experienced. Regions of interest were identified a priori, and brain activity in these regions of interest was compared before and after treatment as well as according to treatment response. A whole brain exploratory analysis with an uncorrected voxel level threshold of pbrain regions that changed after sacral neuromodulation. Among 12 women who underwent a pretreatment functional magnetic resonance imaging exam, seven were successfully treated with sacral neuromodulation and underwent a posttreatment exam. After sacral neuromodulation, brain activity decreased in the left anterior cingulate cortex, bilateral insula, left dorsolateral prefrontal cortex and bilateral orbitofrontal cortex (all pbrain regions with increased activity after sacral neuromodulation. Pretreatment brain activity levels in the bilateral anterior cingulate cortex, right insula, bilateral dorsolateral prefrontal cortex, right orbitofrontal cortex, right supplementary motor area, and right sensorimotor cortex were higher in women who underwent successful treatment (all pBrain activity during urgency changes after successful sacral neuromodulation. Sacral neuromodulation may be more effective in women with higher levels of pretreatment brain activity during urgency. Copyright © 2018 American Urological Association Education and Research, Inc.

    In use of their attributions, granted by the Regulation Law of the 27 Constitutional Article in Nuclear Matter, the National Commission of Nuclear Safety and Safeguards (CNSNS) it has taken charge to the authors the Politics' s elaboration and Guide of Application of Urgency measures and Administrative Sanctions (PGAMASA) with the double objective of discouraging the licensees, contractors and employees of incurring in nonfulfillment or violations to the regulator mark and of encouraging them to be attentive to the prompt identification and the immediate and appropriate correction of the violations and nonfulfillment. The present article presents the legal mark that confers the CNSNS the attributions to implant a PGAMASA and it exposes the more important elements that conform it. The urgency measures and administrative sanctions are defined, the approaches to determine the level of graveness of a violation or nonfulfillment and it is related the application process of urgency measures and administrative sanctions are presented. Like this among the urgency measures they stand out figures like the Notifications of Violation and the Regulatory Orders by their versatility and use potentiality. The PGAMASA has a basically dissuasive character and its last purpose it is to strengthen the actions that the CNSNS carries out in the fulfillment of its functions to maintain the safety standards in the operation of the nuclear facilities.

    2017-12-01

    Clinicians frequently rely on office blood pressure (BP) measurements alone to assess hypertension control, despite widespread acceptance of 24-h ambulatory blood pressure monitoring (ABPM) as the reference standard in the initial diagnosis of hypertension. This study was designed to investigate how often the hypertensive status differed between concurrent office BP versus ABPM measurements, and whether any patient-specific characteristics predict the risk for misclassification by office BP. This study evaluated 42 children with primary hypertension who underwent repeated ambulatory monitoring (190 total recordings) with concurrent office BP measurement as part of their participation in n-of-1 trials. In nearly 40% of the visits, the treatment status by office measurement was opposite to the status by ambulatory monitoring. Office BP underestimated the ambulatory hypertensive status (masked uncontrolled hypertension) in 25% of visits and overestimated ambulatory BP (white coat effect) in 14% of visits. The difference between office BP and ambulatory monitoring was consistent within patients across repeated visits. Patients whose office measurement underestimated or overestimated the ambulatory BP at the first visit were more likely to show persistent discrepancy at subsequent visits. The underuse of ambulatory monitoring in management decisions of children treated for primary hypertension may result in systematic misclassification of hypertension control.

    There is a known association between chemotherapy and radiotherapy for treatment of cancer patients and development or worsening of hypertension. The aim of this article is to review this association. A literature search was conducted for articles reporting this association on the databases PubMed, SciELO and LILACS between 1993 and 2013. There was a high coprevalence of hypertension and cancer, since both diseases share the same risk factors, such as sedentary lifestyle, obesity, smoking, unhealthy diet and alcohol abuse. The use of chemotherapy and adjuvant drugs effective in the treatment of cancer increased the survival rate of these patients and, consequently, increased the incidence of hypertension. We described the association between the use of angiogenesis inhibitors (bevacizumab, sorafenib and sunitinib), corticosteroids, erythropoietin and non-steroidal anti-inflammatory drugs with the development of hypertension. We also described the relationship between hypertension and carotid baroreceptor injury secondary to cervical radiotherapy. Morbidity and mortality increased in patients with cancer and hypertension without proper antihypertensive treatment. We concluded that there is need for early diagnosis, effective monitoring and treatment strategies for hypertension in cancer patients in order to reduce cardiovascular morbidity and mortality.

  1. Vascular Remodeling in Experimental Hypertension

    Directory of Open Access Journals (Sweden)

    Norma R. Risler

    2005-01-01

    Full Text Available The basic hemodynamic abnormality in hypertension is an increased peripheral resistance that is due mainly to a decreased vascular lumen derived from structural changes in the small arteries wall, named (as a whole vascular remodeling. The vascular wall is an active, flexible, and integrated organ made up of cellular (endothelial cells, smooth muscle cells, adventitia cells, and fibroblasts and noncellular (extracellular matrix components, which in a dynamic way change shape or number, or reorganize in response to physiological and pathological stimuli, maintaining the integrity of the vessel wall in physiological conditions or participating in the vascular changes in cardiovascular diseases such as hypertension. Research focused on new signaling pathways and molecules that can participate in the mechanisms of vascular remodeling has provided evidence showing that vascular structure is not only affected by blood pressure, but also by mechanisms that are independent of the increased pressure. This review will provide an overview of the evidence, explaining some of the pathophysiologic mechanisms participating in the development of the vascular remodeling, in experimental models of hypertension, with special reference to the findings in spontaneously hypertensive rats as a model of essential hypertension, and in fructose-fed rats as a model of secondary hypertension, in the context of the metabolic syndrome. The understanding of the mechanisms producing the vascular alterations will allow the development of novel pharmacological tools for vascular protection in hypertensive disease.

    The exercise definition of pulmonary hypertension using a mean pulmonary artery pressure threshold of greater than 30 mmHg was abandoned following the 4th World Pulmonary Hypertension Symposium in 2008, as this definition was not supported by evidence and healthy individuals frequently exceed this threshold. Meanwhile, the clinical value of exercise pulmonary hemodynamic testing has also been questioned. Recent data support the notion that an abnormal pulmonary hemodynamic response during exercise (or exercise pulmonary hypertension) is associated with symptoms and exercise limitation. Pathophysiologic mechanisms accounting for the development of exercise pulmonary hypertension include increased vascular resistance, excessive elevation in left atrial pressure and/or increased volume of trapped air during exercise, resulting in a steep rise in pulmonary artery pressure relative to cardiac output. Recent evidence suggests that exercise pulmonary hypertension may be defined by a mean pulmonary artery pressure surpassing 30 mmHg together with a simultaneous total pulmonary resistance exceeding 3 WU. Exercise pulmonary hypertension is a clinically relevant entity and an improved definition has been suggested based on new evidence. Exercise pulmonary hemodynamics may help unmask early or latent disease, particularly in populations that are at high risk for the development of pulmonary hypertension.

    2016-03-01

    Masked uncontrolled hypertension (MUCH) is diagnosed in patients treated for hypertension who are normotensive in the clinic but hypertensive outside. In this study of 333 veterans with CKD, we prospectively evaluated the prevalence of MUCH as determined by ambulatory BP monitoring using three definitions of hypertension (daytime hypertension ≥135/85 mmHg; either nighttime hypertension ≥120/70 mmHg or daytime hypertension; and 24-hour hypertension ≥130/80 mmHg) or by home BP monitoring (hypertension ≥135/85 mmHg). The prevalence of MUCH was 26.7% by daytime ambulatory BP, 32.8% by 24-hour ambulatory BP, 56.1% by daytime or night-time ambulatory BP, and 50.8% by home BP. To assess the reproducibility of the diagnosis, we repeated these measurements after 4 weeks. Agreement in MUCH diagnosis by ambulatory BP was 75-78% (κ coefficient for agreement, 0.44-0.51), depending on the definition used. In contrast, home BP showed an agreement of only 63% and a κ coefficient of 0.25. Prevalence of MUCH increased with increasing clinic systolic BP: 2% in the 90-110 mmHg group, 17% in the 110-119 mmHg group, 34% in the 120-129 mmHg group, and 66% in the 130-139 mmHg group. Clinic BP was a good determinant of MUCH (receiver operating characteristic area under the curve 0.82; 95% confidence interval 0.76-0.87). In diagnosing MUCH, home BP was not different from clinic BP. In conclusion, among people with CKD, MUCH is common and reproducible, and should be suspected when clinic BP is in the prehypertensive range. Confirmation of MUCH diagnosis should rely on ambulatory BP monitoring. Copyright © 2016 by the American Society of Nephrology.

    The study sought to determine the symptomatic profile of men with lower urinary tract symptoms (LUTS) who visited a urology clinic in Spain and its impact on their health-related quality of life (HRQL). A national, epidemiological cross-sectional study was conducted and included 291 urology clinics. The prevalence of storage LUTS was investigated in 25,482 men. The study collected sociodemographic and clinical data from a subgroup of 1015 patients with storage LUTS who filled out the International Prostate Symptom Score (IPSS), Overactive Bladder Questionnaire Short Form (OABq-SF) and Patient Perception of Bladder Condition (PPBC) questionnaires. The impact of urinary urgency on HRQL was analysed. The prevalence of storage LUTS was 41%, increasing with age: 14.1%, 41.5% and 60.8% for patients aged 18-49, 50-64 and ≥65 years, respectively. Of the 1015 selected patients, only 2.6% had storage symptoms exclusively. Symptom severity (IPSS) increased with age. Nocturia, frequency and urgency were the most common symptoms and had the most impact on HRQL (IPSS and OABq-SF). The number of urgency episodes was inversely correlated with the HRQL (r=-.773; P<.0001). In the multivariate analysis, only the IPSS and OABq-SF bother scores were significant predictors of HRQL (P<.001). Storage LUTS are highly prevalent among patients attending urology clinics in Spain. The severity of the urgency (number of urgency episodes) predicted a poorer quality of life for the patient.

    2012-12-01

    Full Text Available A review on the ethical dilemmas in the diagnosis of hypertension and some elements in the emergence of the bioethics concept was performed. Ethical conflicts that appear at each stage of diagnosis of hypertension: at the time of providing the information, at the point of indication and performance of diagnostic tests, when communicating the diagnosis and during subsequent decision making were identified. We conclude that technological development will introduce new ethical decisions in the diagnosis of hypertension that will increasingly involve the interests of society and create, in one way or another, ethical and moral conflict in the decision making process.

    Menopause coincides with an increase in the incidence of hypertension in women. A direct role of estrogen deprivation in this increased blood pressure remains a topic of debate. Menopause probably accelerates the arterial changes related to aging. Hormone replacement therapy does not influence blood pressure significantly and is not contraindicated in hypertensive women. The effect of hormone replacement treatment on cardiovascular risk was recently the object of controversy. It does not increase risk except in cases of late treatment in older women who already have atherosclerosis. Hypertension management in women is otherwise similar to management in men.

    A study was made of the influence of the constant MKM2-1 magnets on patients suffering from essential hypertension. Continuous action of the magnetic field, created by such magnets, on the patients with stage II essential hypertension was noted to result in a decrease of arterial pressure without the occurrence of any side effects and in a simultaneous reduction of the scope of drug administration. Apart from that fact, magnetotherapy was discovered to produce a beneficial effect on the central hemodynamics and microcirculation. The use of the MKM2-1 magnets may be regarded as a feasible method of the treatment of essential hypertension patients at any medical institution.

    Systematic review, ambispective analysis of observational data. To make recommendations as to whether or not urgent surgical decompression is ever indicated as the optimal treatment for enhancing neurologic recovery in a patient with acute central cord injury without fracture or instability. There are currently no standards regarding the role and timing of decompression in acute traumatic central cord syndrome. In the setting of TCCS without spinal column instability, much controversy exists. We have performed a thorough literature search based on the following question: "Is there a role for urgent (within 24 hours from injury to surgery) surgical decompression in acute central cord syndrome without fracture or instability specifically to enhance neurologic recovery?" Data including patient demographics, mechanism of injury, comorbidities, neurologic status, and surgical treatment was analyzed from a multicenter STSG observational database. Outcome measured included ASIA Motor Score, ASIA Grade, Functional Independence Measure (FIM) Score, SF-36, Sphincter Disturbance, and Ambulatory status. Measures were recorded on admission, discharge, 6 months and 1 year. At 12-month follow-up, early surgery resulted in a 6.31 point greater improvement in total motor score than did the late surgery group, with a P = 0.0358. At 6-month follow-up, early surgery result in higher chance of improvement in ASIA Grade than late surgery, with an odds ratio = 3.39, while at 12-month follow-up early surgery resulted in a higher chance of improvement in ASIA Grade, with an odds ratio of 2.81. Patients who were operated on within 24 hours had 7.79 U more improvement in FIM Total Score than late surgery at 6 month follow-up, with P = 0.0474. The consensus of experts following review of relevant and examination of observational dataset concluded that it is reasonable and safe to consider early surgical decompression in patients with profound neurologic deficit (ASIA = C) and persistent

    Pulmonary hypertension is defined as an increase of mean pulmonary arterial pressure ≥25 mmHg at rest as assessed by right heart catheterization. According to different combinations of values of pulmonary wedge pressure, pulmonary vascular resistance and cardiac output, a hemodynamic classification of pulmonary hypertension has been proposed. Of major importance is the pulmonary wedge pressure which allows to distinguish pre-capillary (pulmonary wedge pressure ≤15 mmHg) and post-capillary (pulmonary wedge pressure >15 mmHg) pulmonary hypertension. Pre-capillary pulmonary hypertension includes the clinical groups 1 (pulmonary arterial hypertension), 3 (pulmonary hypertension due to lung diseases and/or hypoxia), 4 (chronic thrombo-embolic pulmonary hypertension) and 5 (pulmonary hypertension with unclear and/or multifactorial mechanisms). Post-capillary pulmonary hypertension corresponds to the clinical group 2 (pulmonary hypertension due to left heart diseases).

    Arterial hypertension is a common worldwide disease with a prevalence of approximately 26%. Secondary cause is known in 5-10% of patients with hypertension. We should think of secondary hypertension in all patients with resistant hypertension, in patients with sudden deterioration in the control of hypertension and in patients with laboratory and clinical signs of diseases associated with secondary hypertension. It is important to distinguish between secondary hypertension and pseudo-resistance (noncompliance to treatment, white coat syndrome). Secondary causes of hypertension can be divided into endocrine (primary aldosteronism, pheochromocytoma, hypercortisolism, hyperparathyreoidism), renal - renovascular and renal parenchymal hypertension, and other causes as sleep apnoe syndrome, hypertension in pregnancy, coarctation of the aorta and intracranial tumors.

  15. Sex differences in primary hypertension

    2012-01-01

    Men have higher blood pressure than women through much of life regardless of race and ethnicity. This is a robust and highly conserved sex difference that it is also observed across species including dogs, rats, mice and chickens and it is found in induced, genetic and transgenic animal models of hypertension. Not only do the differences between the ovarian and testicular hormonal milieu contribute to this sexual dimorphism in blood pressure, the sex chromosomes also play a role in and of themselves. This review primarily focuses on epidemiological studies of blood pressure in men and women and experimental models of hypertension in both sexes. Gaps in current knowledge regarding what underlie male-female differences in blood pressure control are discussed. Elucidating the mechanisms underlying sex differences in hypertension may lead to the development of anti-hypertensives tailored to one's sex and ultimately to improved therapeutic strategies for treating this disease and preventing its devastating consequences.

  20. [Menopause: Hypertension and vascular disease].

    Science.gov (United States)

    Zilberman, J M

    Hypertension is the main cardiovascular risk factor affecting 25% of women. Hormone changes and hypertension after menopause may lead to higher target organ damage and cardiovascular disease such as increased arterial stiffness, coronary diseases, chronic heart failure and stroke. The physiopathological mechanisms involved in the development of hypertension and cardiovascular diseases in menopausal women are controversial. There are pharmacokinetic and pharmacodynamic differences in both sexes, the women have more coughing when using the converting-enzyme inhibitors, more cramps when using thiazide diuretics and more oedema in the inferior limbs when using calcium antagonists. The aim of this review is to analyse possible physiopathological mechanisms involved in hypertension after menopause and to gain a better understanding of the biological effects mediated by vascular ageing in women when the level of oestrogen protective effect decreases over the vascular system.

    Full Text Available Hypertension can begin early in childhood, as occasional increases in blood pressure or abnormal blood pressure responses to physical or emotional stress. High blood pressure in juvenile age is defined as a blood pressure repeatedly above the 95th percentile of specific nomograms. Its worldwide prevalence ranges from 1% to about 10%. The purpose of this paper is to perform an overview about characteristics, diagnosis, risk factors, therapy, and prognosis of paediatric hypertension.

    Hypertension in pregnancy has several forms that differ by their mechanisms and their consequences for mothers and fetus. Chronic hypertension is defined by SBP≥140mm Hg or DBP≥90mm Hg before pregnancy or before the 20th week of amenorrhea. Gestational hypertension is defined by SBP≥140mm Hg or DBP≥90mm Hg during or after the 20th week of amenorrhea. Preeclampsia is the occurrence of hypertension and proteinuria after 20weeks of amenorrhea. Severe preeclampsia is accompanied by clinical signs and symptoms indicating visceral pain. The HELLP syndrome is a severe preeclampsia accompanied by intravascular hemolysis and hepatic cytolysis. Eclampsia is characterized by seizures of the tonic-clonic type. A chronic hypertension is observed in 1-5% of pregnancies. Gestational hypertension without proteinuria appears in 5-6% of pregnancies. A preeclampsia develops in 1-2% of pregnancies, but much more frequently (up 34%) in the presence of risk factors. High blood pressure during pregnancy remains, by its complications, the leading cause of maternal morbidity and mortality. Copyright © 2016 Elsevier Masson SAS. All rights reserved.

    2011-11-01

    Despite the abundance of antihypertensive drugs, resistant hypertension remains a major clinical problem. Recent technological advances render interventional management of resistant hypertension one of the hottest topics in the hypertension field. The aim of this review is to present the pathophysiologic background and the mechanisms mediating blood pressure reduction after renal sympathetic denervation, to analyze recent findings with this fascinating approach and to critically suggest future research directions. Catheter-based, ablation-induced renal sympathetic denervation was initially studied in 45 patients with resistant hypertension in a proof-of-concept study. Impressive blood pressure reductions of about 30/15  mmHg were achieved at 6 months, without serious complications. A second, controlled, randomized (but not blinded) study confirmed the results, verifying the efficacy and safety of the procedure. A recent report revealed the 2-year durability of blood pressure reduction. Data published so far indicate that ablation-induced renal denervation is a feasible, effective, and well tolerated interventional approach for the management of resistant hypertension. The groundbreaking studies of renal denervation in drug-resistant hypertension pave the way for further research in other disease conditions in which sympathetic overactivity seems to play a critical role. This initial wave of enthusiasm needs to be followed by rigorous investigation, for the proper identification of the potential and the limitations, indications, and contraindications of this approach.

Studies from the last two decades have provided strong evidence for a causal role of OSA in the development of systemic hypertension. The acute physiological changes that occur during apnea promote nocturnal hypertension and may lead to the development of sustained daytime hypertension via the pathways of sympathetic activation, inflammation, oxidative stress, and endothelial dysfunction. This review will focus on the acute hemodynamic disturbances and associated intermittent hypoxia that characterize OSA and the potential pathophysiological mechanisms responsible for the development of hypertension in OSA. In addition the epidemiology of OSA and hypertension, as well as the role of treatment of OSA, in improving blood pressure control will be examined.Keywords: obstructive sleep apnea, hypertension, intermittent hypoxia, ambulatory blood pressure, sympathetic activation

    Full Text Available The object of the paper is to analyze the spatial structure of land and identification of the needs of consolidation works and exchange of land in the villages of the Sławno municipality, lying in the district of Opoczno, in the Łódzkie Voivodship. The authors use the method of zero unitarisation for the purposes of determining the order of undertaking consolidation works and exchange of land in the area of research. The basis for calculation is the database of 19 factors (x1–x19 characteristic for the listed five groups of issues, describing each of the following villages. The obtained results, in a form of synthetic meter for each village, allowed creating the hierarchy of the urgency of carrying out consolidation works. The problem of excessive fragmentation of farms, constituting the collections of a certain number of parcels, in a broader sense, is one of the elements that prevent the acceleration of reforms by conversion of the Land and Buildings Register (EGiB in a full valuable real estate cadastre in Poland. The importance of the problem is highlighted by the fact that there are ecological grounds in the study area, significant from the point of view of environmental protection.

    Adolescents are seeking new references and experiences, which may involve attitudes of risk and exposure to accidents and violence from external causes. These events constitute a serious Public Health problem. The scope of this study was to analyze the occurrence of accidents by external causes in adolescents from 10 to 19 years of age attended at sentinel urgency and emergency services in Brazil. Data from the 2009 Surveillance System for Violence and Accidents (VIVA 2009) was analyzed in 74 emergency units in 23 state capitals and the Federal District. The findings revealed that 6,434 adolescents (89.8%) were victims of accidents and 730 (10.2 %) were victims of violence. The main causes of the accidents were falls and traffic accidents, and assaults were predominant in violence. For both accidents and violence, non-white male adolescents were predominant and the events occurred most frequently on the public highways. A marked increase was detected, with hospitalization of victims of violence between 15 and 19 years of age. Understanding the epidemiological reality of external causes among adolescents represents an important tool for health prevention and promotion policies and the culture of peace seeking to reduce morbidity and mortality.

    In the past six years, we have had experience with 40 patients with hypertensive thalamic hemorrhages, as verified by CT scan at our hospital within 24 hours. These patients were classified into the following three groups according to the location of the bleeding point and the size of the hematoma: (1) anteromedial (4 cases), (2) posterolateral (16 cases), and (3) massive (20 cases). The (1) and (2) hematomas were small (less than 3 cm in diameter), while those in (3) were large (more than 3 cm in diameter). Twenty cases (50% of all the thalamic hematomas) were small hematomas. The characteristic clinical symptoms of the anteromedial type were a mild disturbance of consciousness and thalamic dementia, while those of the posterolateral type were motor and sensory disturbance, and thalamic aphasia, respectively. Twenty cases (50%) were large hematomas. The clinical symptoms of these cases were mainly consciousness disturbance; 7 of them expired. Based on this experience, it may be considered that the patients whose hematoma size was larger than 3 cm had a poor prognosis and that the patients with the posterolateral type had a poor functional diagnosis.

    A prospective randomised trial was carried out to see whether paranormal healing by laying on of hands might reduce blood pressure in essential hypertension and whether such an effect might be due to a paranormal, psychological, or placebo factor. Patients were randomised to three treatment groups: paranormal healing by laying on of hands (n=40), paranormal healing at a distance (n=37), and no paranormal healing (controls; n=38). Healing at a distance and no paranormal healing were investigated double blind. Systolic and diastolic blood pressures were significantly reduced in all three groups at week 15 (mean reduction (95% confidence interval) 17·1 (14·0 to 20·2)/8·3 (6·6 to 10·0) mm Hg). Only the successive reductions in diastolic blood pressures among the groups from week to week were significantly different. Each week diastolic pressure was consistently lower (average 1·9 mm Hg) after healing at a distance compared with control, but on paired comparison these differences were not significant. Probably week to week variations among the groups accounted for any differences noted. In this study no treatment was consistently better than another and the data cannot therefore be taken as evidence of a paranormal effect on blood pressure. Probably the fall in blood pressure in all three groups either was caused by the psychosocial approach or was a placebo effect of the trial itself. PMID:3134082

    Melatonin, due to its multiple means and mechanisms of action, plays a fundamental role in the regulation of the organismal physiology by fine tunning several functions. The cardiovascular system is an important site of action as melatonin regulates blood pressure both by central and peripheral interventions, in addition to its relation with the renin-angiotensin system. Besides, the systemic management of several processes, melatonin acts on mitochondria regulation to maintain a healthy cardiovascular system. Hypertension affects target organs in different ways and cellular energy metabolism is frequently involved due to mitochondrial alterations that include a rise in reactive oxygen species production and an ATP synthesis decrease. The discussion that follows shows the role played by melatonin in the regulation of mitochondrial physiology in several levels of the cardiovascular system, including brain, heart, kidney, blood vessels and, particularly, regulating the renin-angiotensin system. This discussion shows the putative importance of using melatonin as a therapeutic tool involving its antioxidant potential and its action on mitochondrial physiology in the cardiovascular system.

    Full Text Available Background: aging-associated diseases contribute to morbidity and mortality in the population; therefore, it is necessary to develop intervention strategies to prevent and/or minimize their consequences. Objectives: to evaluate the effectiveness of a cognitive-behavioral intervention aimed at older hypertensive patients treated in primary care in Cardenas and Santiago de Cuba municipalities during 2011-2013. Methods: an intervention study of older adults with hypertension was conducted in two municipalities: Santiago de Cuba and Cárdenas. The intervention group was composed of 399 older patients living in the catchment areas of the Carlos Juan Finlay and Héroes del Moncada polyclinics while the control group included 377 older adults served by the Julian Grimau and Jose Antonio Echeverría polyclinics. The intervention consisted of a systematic strategy to increase knowledge of the disease in order to change lifestyles. Results: in the intervention group, there were more patients with sufficient knowledge of the disease (OR: 1.82, greater control of hypertension (OR: 1.51 and better adherence to treatment (OR: 1.70. By modeling the explanatory variables with hypertension control, being in the intervention group (OR: 0.695 and adhering to treatment (OR: 0.543 were found to be health protective factors. Conclusion: the congnitive-behavioral intervention for older adults treated in primary care of the municipalities studied was effective in improving blood pressure control since it contributed to a greater adherence to treatment.

    Arterial hypertension is the most common chronic disease in developed countries and it is the leading risk factor for stroke, ischemic heart disease, congestive heart failure, chronic renal failure and peripheral artery disease. Its prevalence appears to be about 30-45% of the general population. Recent European guidelines estimate that up to 15-20% of the hypertensive patients are not controlled on a dual antihypertensive combination and they require three or more different antihypertensive drug classes to achieve adequate blood pressure control. The guidelines confirmed that diuretics, beta-blockers, calcium-channel blockers, angiotensin-converting enzyme inhibitors and angiotensin receptor blockers are suitable for the initiation and maintenance of antihypertensive treatment, either as monotherapy or in combination therapy. Very few antihypertensive agents have reached the market over the last few years, but no new therapeutic class has really emerged. The long-term adherence to cardiovascular drugs is still low in both primary and secondary prevention of cardiovascular diseases. In particular, the issue of compliance is persistently high in hypertension, despite the fixed-dose combination therapy. As a consequence, a cohort of high-risk hypertensive population, represented by patients affected by refractory and resistant hypertension, can be identified. Therefore, the need of controlling BP in high-risk patients may be addressed, in part, by the development of new drugs, devices and procedures that are designed to treat hypertension and comorbidities. In this review we will comprehensively discuss the current literature on recent therapeutic advances in hypertension, including both medical therapy and interventional procedures.

    Careful planning is essential to ensure blood availability during shortages. Triaging supply is one proposed strategy; however, few data concerning the urgency of transfusion are available to inform planning. This study sought to determine the proportion of red blood cells (RBCs) used for clinically urgent indications. A total of 5132 RBC units were randomly selected at point of production and distributed into general statewide inventory over a 9-month period. These selected units carried case report forms, for completion at the point of hospital issue for transfusion. Completed forms were returned to the blood service for collation and analysis, capturing information on indication and clinical urgency of supply, including use for potentially deferrable elective surgery. Data from 5052 RBC units indicated that 95.6% were transfused. Approximately one-third of transfused units were used to support surgery, one-third for hematology/oncology, and one-third for other medical and miscellaneous indications. Where used for surgery, 25.7% (95% confidence interval [CI], 23.4%-28.0%) were for elective procedures, although urgency of surgery was unknown in 17.1% (95% CI, 15.2%-19.2%) of cases. Supply for nonurgent medical indications and elective surgery only accounted for 9.8% (95% CI, 9.0%-10.6%) of use, with 53.4% (95% CI, 52.0%-54.8%) of RBCs required within 24 hours. The majority of RBCs are transfused with a high degree of clinical urgency, with only a minor proportion required to support elective surgery.

  17. Accelerated Hypertension after Venlafaxine Usage

    Full Text Available Venlafaxine is the first antidepressant that acts via inhibiting serotonin and noradrenaline reuptake. Hypertension is observed in doses exceeding 300 mg/day and is the most feared complication. We report a patient with accelerated hypertension after venlafaxine use observed at a dose of 150 mg/day. A 23-year-old patient with symptoms of insomnia, depression, anhedonia, fatigue admitted our clinic. Venlafaxine at a dose of 75 mg/day was initiated after he was diagnosed with major depressive disorder. After 5 months, venlafaxine dose was uptitrated to 150 mg/day due to inadequate response to drug. After using venlafaxine for ten months at the dose of 150 mg/day, he admitted our clinic with headache and epistaxis. He was hospitalized after his blood pressure was measured as 210/170 mmHg. No secondary causes for hypertension were found, and venlafaxine treatment was considered possible etiologic factor. After stopping venlafaxine treatment, his blood pressure was reverted back to normal limits. While mild elevation of blood pressure could be observed after venlafaxine treatment, this case shows that accelerated hypertension with a diastolic blood pressure rise above 120 mmHg could be observed at relatively low doses of venlafaxine. Close monitoring of blood pressure is necessary after initiation of treatment, as accelerated hypertension could cause endorgan damage with potentially catastrophic results.

  18. Heat stress proteins in hypertension

    1986-01-01

    It has been described that spontaneously hypertensive rats (SHR) are more sensitive to an acute environmental heat stress and that cultured cardiomyocytes from neonatal SHR are demonstrated to be more thermosensitive. In addition, chronically heat exposed spontaneously hypertensive mice leads to a decrease of blood pressure in these animals. Heat shock is known to induce the synthesis of a new set of proteins (HSP) in every cell tested. This ubiquitous response seems to be involved in the induction of a thermotolerant state. The synthesis of 70K HSP was observed in lymphocytes isolated from the spleen of chronically heated mice. They used lymphocytes, previously isolated on a ficoll gradient, to evaluate the HSP induction in normotensive (WKY) and hypertensive (SHR) rats. The heat shock was induced by exposing the lymphocytes at 46 0 C during 5 min in a hot water bath. The cells were then labeled with ( 75 Se)-methionine, washed, homogenized and separated on 5-30% SDS-polyacrylamide gel. Preliminary results suggest an abnormal pattern of induction of 70K and 90K HSP in hypertension. Heat sensitivity, thermotolerance and expression of HSP may, thus, be related to hypertension

    To determine whether long-term very vigorous endurance training prevents hypertension. Cohort study of master orienteering runners and controls. Finland. In 1995, a health questionnaire was completed by 264 male orienteering runners (response rate 90.4%) who had been top-ranked in competitions among men aged 35-59 years in 1984, and by 388 similarly aged male controls (response rate 87.1%) who were healthy at the age of 20 years and free of overt ischemic heart disease in 1985. Self-report of medication for hypertension. In the endurance athlete group, the crude prevalence (8.7%) of subjects who had used medication for hypertension was less than a third of that in the control group (27.8%). Even after adjusting for age and body mass index, the difference between the groups was still significant (odds ratio for athletes 0.43, 95% confidence interval 0.25-0.76). Long-term vigorous endurance training is associated with a low prevalence of hypertension. Some of the effect can be explained by a lower body mass, but exercise seems to induce a lower rate of hypertension by other mechanisms than by decreasing body weight

    Full Text Available Hypertension is a frequent, chronic cardiovascular disease both in industrially developed and developing countries; its frequency ranges between 20 and 40 %. Although the prevalence of hypertension in women is lower than that in men, it reaches 70% to 80% in women above 70 years of age, and is a strong predictor of cardiovascular risk. Osteoporosis (OP is systematic skeletal disorder with lower bone mass and damages of bone tissue microarchitecture. The aim of this study was to ascertain the association between hypertension and osteoporosis as two mass noninfectious deceases.The examination involved three hundred postmenopausal women who came for densitometry inspection; none of them had some major cardiovascular event (myocardial infarction, cerebrovascular stroke and ischemic heart disease. From all of them were taken personal data, personal and familial case histories. The parameters used in the further analysis were: body mass, body height, waist circumference, blood pressure; laboratory analysis: cholesterol, HDL, LDL, glycemia, Ca and P in serum and Ca in urine. In addition, there was calculated a ten-year risk of cardiovascular event according to SCORE system, using tables for high risk; bone mineral density on Hologic Discovery QDR-C was shown as T score on the lumbar part of the spinal column. The patients were divided into tree groups based on the measures of bone density: the patients with osteoporosis - bone density with T score lower than 2.5 SD (100 patients; patients with osteopenia - T score from -1 to -2,5 SD (100, and control group of patients with normal bone density T score from +1 to -1 SD (100.The mean age of postmenopausal women (control group with normal bone density was 54.10±3.90 years; 56.63±4.76 years in the group with osteopenia (group II; and 60.14±3.55 years in the group of postmenopausal women with osteoporosis.The analysis of variance (ANOVA and post hoc Dunett`s test showed that there were statistically

    Although waste from coffee processing is a valuable resource to make biogas, compost, and nutrient-rich animal food, it is usually dumped into nearby water courses. We carried out water quality assessment at 44 sampling sites along 18 rivers that receive untreated waste from 23 coffee pulping and processing plants in Jimma Zone, Ethiopia. Twenty upstream sampling sites free from coffee waste impact served as control, and 24 downstream sampling sites affected by coffee waste were selected for comparison. Physicochemical and biological results revealed a significant river water quality deterioration as a result of disposing untreated coffee waste into running water courses. During coffee-processing (wet) season, the highest organic load (1,900 mg/l), measured as biochemical oxygen demand, depleted dissolved oxygen (DO) to a level less than 0.01 mg/l, and thus curtailed nitrification. During off season, oxygen started to recuperate and augmented nitrification. The shift from significantly elevated organic load and reduced DO in the wet season to increased nitrate in the off season was found to be the determining factor for the difference in macroinvertebrate community structure as verified by ordination analysis. Macroinvertebrate diversity was significantly reduced in impacted sites during the wet season contrary to the off season. However, there was a significant difference in the ratio of sensitive to pollution-tolerant taxa in the off season, which remained depreciated in the longer term. This study highlights the urgency of research exploring on the feasibility of adopting appropriate pollution abatement technologies to implement ecologically sound coffee-processing systems in coffee-growing regions of Ethiopia.

    Introduction This paper describes the rationale and methodology a study which investigates mind-body treatment versus pharmacotherapy for women with urgency urinary incontinence (UUI). To explore brain associations in UUI, a subset of patients will also undergo functional magnetic resonance imaging (fMRI). We hypothesize that hypnotherapy a mind-body intervention, will be at least as effective pharmacotherapy in treating UUI. We also hypothesize that fMRI findings will change following treatment, with changes potentially differing between groups. Methods The purpose of this manuscript is to recount the development and design challenges of a study evaluating the efficacy of hypnotherapy compared to conventional pharmacotherapy in UUI treatment. The study randomizes women to either of these treatments and outcome measures include bladder diaries and validated questionnaires. Sample size estimates, based on a non-inferiority test (alpha=.025, beta=0.20), after considering drop-out/loss to follow-up, indicated approximately 150 woman would be required to test the hypothesis that hypnotherapy is non-inferior to pharmacotherapy within a 5% non-inferiority margin. The study will also evaluate fMRI change in a subset of participants before and after therapy. Study challenges included designing a study with a mind-body therapy and a comparison treatment equally acceptable to participants, standardizing the interventions, confronting the reality that trials are time-consuming for participants and making appropriate accommodations. Results Study enrollment began March 2013 and is ongoing. Conclusions This manuscript details the design a of randomized controlled trial (RCT) comparing mind-body therapy to medications in treatment of UUI and describes the challenges encountered in its planning.

    To estimate the prevalence, awareness and control of prehypertension (preHT) and hypertension (HT) as defined by JNC-7 criteria in the Trabzon Region and its associations with demographic factors (age, sex, obesity, marital status, reproductive history in women and level of education), socioeconomic factors (household income and occupation), family history of selected medical conditions (diabetes, hypertension, obesity and cardiovascular disease), lifestyle factors (smoking habits, physical activity and alcohol consumption) in the adult population. In this cross-sectional survey, a sample of households was systematically selected from the central province of Trabzon and its nine towns. A total of 4809 adult subjects (2601 women and 2208 men) were included in the study. Demographic and socioeconomic factors, family history of selected medical conditions, and lifestyle factors were obtained for all participants. Systolic blood pressure (BP) and diastolic BP levels were measured for all subjects. The persons included in the questionnaire were invited to the local medical centers for blood examination between 08:00-10:00 following 12 hours of fasting. The levels of serum glucose (FBG), total cholesterol (Total-C), high density cholesterol (HDL-C), low density cholesterol (LDL-C) and triglycerides were measured with autoanalyzer. Definition and classification of HT was performed according to guidelines from the US JNC-7 report. Prevalence, awareness, treatment and control of HT were assessed. The prevalences of HT and preHT were 44.0% (46.1% in women and 41.6% in men) and 14.5% (12.6% in women and 16.8% in men), respectively. Overall, only 41% of the hypertensive individuals had been previously diagnosed. Furthermore, 54.5% of the hypertensive subjects were being treated with antihypertensive drugs (AHD), but only 24.3% of treated subjects had their BP adequately controlled. Among all hypertensive subjects (known and newly diagnosed), only 5.43% had their BP under

    A novel model of nutritionally induced hypertension in the rat is described. Dietary obesity was produced by providing sweet milk in addition to regular chow, which elicited a 52% increase in caloric intake. Despite 54% greater body weight gain and 139% heavier retroperitoneal fat pads, 120 days of overfeeding failed to increase systolic pressure in the conscious state or mean arterial pressure under urethan anesthesia. In contrast, mild hypertension developed in intermittantly fasted obese animals. The first 4-day supplemented fast was initiated 4 wk after the introduction of sweet milk, when the animals were 47 g overweight relative to chow-fed controls. Thereafter, 4 days of starvation were alternated with 2 wk of refeeding for a total of 4 cycles. A rapid fall in systolic blood pressure accompanied the onset of supplemented fasting and was maintained thereafter. With refeeding, blood pressure rose precipitously, despite poststarvation anorexia. Blood pressure tended to rise slightly over the remainder of the realimentation period. After the 4th supplemented fast, hypertension was sustained during 30 days of refeeding. Cumulative caloric intake in starved-refed rats fell within 2% of that in chow-fed controls. Refeeding hypertension appeared to be due to increased sympathetic nervous activity, since (1) cardiac β-adrenergic receptors were downregulated, as indicated by a 40% decrease in the maximum binding of [ 3 H]dihydroalpranolol; and (2) the decrease in heart rate as a result of β-blockade was enhanced. Refeeding hypertension in the dietary obese rat may be a potential animal model for some forms of human obesity-related hypertension

    Full text: Imaging is very important in diagnosing renovascular hypertension (RVHT). The role of color duplex Doppler, CT angiography, MR angiography and DS angiography will be presented, advantages and disadvantages discussed. The treatment of RVHT can be medical, surgical or endovascular. Endovascular treatment is a domain of vascular interventional radiology; endovascular treatment of renovascular hypertension consists of PTA alone or PTA and stenting of renal arteries in patients who have haemodynamically significant stenosis of renal artery due to fibromuscular dysplasia or atherosclerosis. Atherosclerotic renal artery stenosis results in increased production of renin, angiotensin II, aldosterone; plasma rennin activity of is increased in renal vein of ischemic kidney that retains sodium and water. Atherosclerotic lesions are typically ostial. Long-standing hypertension damages intrarenal vessels of unprotected kidney. Hypertension and renal failure may persist after removal of stenotic kidney. It usually affects older people. Fibromuscular dysplasia is non-atherosclerotic, is more common in women, occurs at younger age (average 35 yrs). Treatment of choice is PTA alone. Results are much better than in atherosclerotic RAS, where PTA + stenting are indicated. Endovascular treatment may result in complications, minor local or major complications, mostly related to the interventional technique. While PTA for the treatment of FMD is clearly indicated, the conflicting data exist over years regarding indications, benefits, complications and advantages of PTA / stent over medical therapy for treatment of atherosclerotic renovascular hypertension. Although 25-30% of patients with impaired renal function can recover glomerular filtration after revascularization, many have no apparent change in kidney function and 19-25% experience a significant loss of kidney function, some as a result of atheroemboli. The results of ASTRAL, STAR and CORAL studies will be presented

    Obesity is prevalent worldwide and associated with co-morbidities that result in increased cardiovascular risk. Hypertension is the most prevalent obesity comorbidity associated with increased cardiovascular risk. Obesity hypertension is a distinct subtype of essential hypertension. While endogenous Cushing's syndrome is an uncommon cause of both obesity and hypertension, the recent recognition of other hypercortisolemic states has raised the profile of hypercortisolism as an important contributor in obesity hypertension. The high prevalence of exogenous, iatrogenic, pseudo, and subclinical Cushing's syndromes makes hypercortisolism an important diagnostic consideration in the evaluation and management of patients with obesity hypertension who are resistant to conventional management. Available data suggest that the renin-angiotensin-aldosterone system modulating antihypertensives have the best efficacy in hypercortisolism-mediated obesity hypertension. Strategies aimed at reducing cortisol production and action also have utility. This review provides a comprehensive overview of the epidemiology, etiopathogenesis and management options available for glucocorticoid-mediated obesity hypertension.

    1986-01-01

    Four pediatric patients with extrahepatic portal hypertension had undergone portography and computerized radionuclide angiography in order to examine shape of portal system and to evaluate hepatic blood flow before and aftersurgical treatment. In all patients, cavernous transformation of portal system was demonstrated by portography, and in one of them spontaneous splenorenal shunt occurred. In 3 of them, who underwent esophageal transsection combined with paraesophagogastric devascularization and splenectomy, so-called direct operation, increase of portal blood flow was revealed by computerized radionuclide angiography. It is suggested that direct operation increasing portal blood flow after surgery is effective in treating extrahepatic portal hypertension in childhood. (author)

    In 43 patients with obstructive and restrictive lung disease a catheterisation of the right heart with measurement of pulmonary artery pressure was performed. In a retrospective study several radiological parameters of pulmonary hypertension were evaluated on the chest radiographs of these patients. Considering those parameters on the p.a. and lateral chest radiograph, the diagnosis of pulmonary hypertension in patients with elevated pulmonary artery pressure at rest can be made with great accuracy. When pulmonary artery pressure is elevated only during exercise, the accuracy of radiological diagnosis is much lower. (orig.) [de

    1992-09-01

    We examined 23 patients with pulmonary hypertension of varying aetiology by MRI and compared the results with those of right heart catheterisation. The best correlation was obtained between right ventricular mural thickness and mean pulmonary pressure (R = 0.91, p = 0.001). There was significant correlation (R = 0.85, p = 0.001) for the diameter of the inferior vena cava, which was dilated in all patients with pulmonary hypertension. There was no significant correlation between mean pulmonary pressure and the diameters of the superior vena cava or the main pulmonary artery branches (R = 0.55 and 0.75 respectively, p < 0.05). Amongst functional measurements there was a correlation between right ventricular ejection fraction and mean pulmonary artery pressure (R = 0.71, p = 0.001). There was no correlation between right ventricular end-systolic and end-diastolic volume. In all patients with pulmonary hypertension, dynamic flow sensitive gradient echo sequences showed the presence of tricuspid insufficiency. A further semiquantitative criterion for the presence of pulmonary hypertension in 4 patients (17%) was an abnormal signal from the main pulmonary artery in early to mid-systole shown on T[sub 1]-weighted transverse sections.

    2006-01-01

    Models to predict diabetes or pre-diabetes often incorporate the assessment of hypertension, but proposed definitions for 'hypertension' are inconsistent. We compared the classifications obtained using different definitions for 'hypertension'. We compared records for 5158 cases from 181 family practices, who were later diagnosed with diabetes and prescribed oral hypoglycaemic drugs, with 5158 controls, matched for age, sex and family practice, who were never diagnosed with diabetes. We compared classifications obtained using definitions of hypertension based on medical diagnoses, prescription of blood pressure lowering drugs or both. We compared family practices where diagnosis or prescribing varied systematically. Classification of hypertension based on recorded medical diagnoses gave a sensitivity of 32.2% for diabetes (95% confidence interval from 30.4 to 34.1%). Prescription of blood pressure lowering drugs in the 12 months before diagnosis gave a sensitivity of 47.2% (45.7 to 48.7%). Combining either a medical diagnosis or a blood pressure lowering prescription gave a sensitivity of 52.8% (51.3 to 54.3%). In family practices where hypertension was least frequently recorded, a diagnosis of hypertension gave a sensitivity of 19.5% for diabetes (17.4 to 21.6%) compared with 50.8% (46.3 to 55.3%) in the highest quintile. Prescription of blood pressure lowering drugs gave a sensitivity of 36.1% (33.1 to 39.0%) in the lowest prescribing practices but 58.2% (55.5 to 61.0%) in the highest quintile. Misclassification errors depend on the definition of hypertension and its implementation in practice. Definitions of hypertension that depend on access or quality in health care should be avoided.

  2. [Guidelines for management of hypertension: why doesn't evidence lead to unanimity?].

    2009-01-01

    Guidelines are systematically developed statements to assist practitioner and patient decisions, and are being used to describe care based on scientific evidence. However, presence of multiple guidelines on the same subject does not help physicians make the best decision about healthcare. In this paper we examined the more recent guidelines (GL) for the management of arterial hypertension: World Health Organization-International Society of Hypertension (WHO-ISH) GL, European Society of Hypertension-European Society of Cardiology (ESH-ESC) GL, British Hypertension Society (BHS-IV) GL, and the report of Joint National Committee (JNC-7) from USA. Some differences emerged on the definition of hypertension, the blood pressure targets and the thresholds for treatment, the quantification of cardiovascular risk, the choice of initial drugs. These differences are likely to be based on divergent opinions about the relationship between hypertension and global cardiovascular risk (CVR). In the JNC-7 report, hypertension is thought to be the mainstay of CVR, hence BP treatment is to be started, taking into account the entity of blood pressure values and apart from other risk factors (with the exception of diabetes and renal insufficiency). The other GL, particularly BHS-IV GL, establish the thresholds for the start of treatment mainly taking into account the global CVR. Actually, BHS-IV GL do not recommend the start of pharmacological treatment in mild hypertension, provided that the global CVR was lower than 20% in ten years. Moreover, the difference in definition of hypertension, BP targets, choice of starting drug, is likely to spring from this different view on hypertensionglobal cardiovascular risk relationship.

  3. Rifampicin and anti-hypertensive drugs in chronic kidney disease: Pharmacokinetic interactions and their clinical impact

    Directory of Open Access Journals (Sweden)

    Full Text Available Patients on dialysis have an increased incidence of tuberculosis (TB. Rifampicin, a first-line antitubercular therapy (ATT drug, is a potent inducer of hepatic cytochrome P450 (CYP. There is potential for pharmacokinetic interaction between rifampicin and anti-hypertensives that are CYP substrates: amlodipine and metoprolol. Therefore, hypertensive patients receiving rifampicin-based ATT are at risk for worsening of hypertension. However, this hypothesis has not yet been systematically studied. In this prospective study, hypertensive CKD 5D patients with TB were followed after rifampicin initiation. Blood pressure (BP was ≤140/90 mmHg with stable anti-HT requirement at inclusion. Serum amlodipine, metoprolol, and prazosin levels were estimated by high-performance liquid chromatography at baseline and 3, 7, 10, and 14 days after rifampicin initiation. BP and anti-HT requirement were monitored for 2 weeks or until stabilization. All 24 patients in the study had worsening of hypertension after rifampicin and 83.3% required increase in drugs to maintain BP 50% in all patients and became undetectable in 50-75%. Drug requirement increased from 4.5 ± 3.6 to 8.5 ± 6.4 units (P < 0.0001. Mean time to first increase in dose was 6.5 ± 3.6 days. Eleven (46% patients experienced a hypertensive crisis at 9.1 ± 3.8 days. Three of them had a hypertensive emergency with acute pulmonary edema. In two patients, rifampicin had to be discontinued to achieve BP control. In conclusion, rifampicin caused a significant decrease in blood levels of commonly used anti hypertensives. This decrease in levels correlated well with worsening of hypertension. Thus, we suggest very close BP monitoring in CKD patients after rifampicin initiation.

    2013-05-01

    In the majority of hypertensive patients, no particular cause for abnormal blood pressure is evident (primary or essential hypertension). In contrast, in the minority of patients with secondary hypertension a specific underlying cause is responsible for the elevated blood pressure. The prevalence of secondary hypertension is higher in patients with resistant hypertension than in the general hypertensive population and increases with age. The list of secondary forms of hypertension is long and prevalence of the individual causes of secondary hypertension varies. Hence, this review divides them into two categories: common causes and rare causes. If appropriately diagnosed and treated, patients with a secondary form of hypertension might be cured, or at least show an improvement in their blood pressure control. Consequently, screening for secondary causes of hypertension plays an essential part in the care of patients with arterial hypertension. If the basal work-up raises the suspicion of a secondary cause of hypertension, specific diagnostic procedures become necessary, some of which can be performed by primary care physicians, while others require specialist input.

    To assess the knowledge of the hypertensive patients about their hypertension and their relation to its control. Cross-sectional study among 400 hypertensive patients, all over 18 years, selected from 50 primary-care centres, who responded to an hypertension-related survey. Included variables were survey items, age, gender, educational level, professional occupation, blood pressure data and antihypertensive treatment. The obtained differences were analyzed using the chi-square test, Kruskal-Wallis, Wilcoxon, Anova and Bonferroni methods. There were 323 valid surveys. 52.9% of respondents were women, the average age: 65.4 years (SD: 11.2), 54.8% of them had primary education. 39.6% were aware of the objectives of systolic BP control. Only 19.6% having knowledge of those for diastolic BP control, with no differences between controlled and uncontrolled (systolic BP: 39% vs 38.1%, P=.887; diastolic BP: 19.2% vs 21%, P=.721). Over 70% knew about lifestyle changes, without significant differences between controlled and uncontrolled respondents. 82% of controlled respondents, and 79% of those uncontrolled, recognized the chronical nature of the treatment (P=.548), but 15.1% of the controlled respondents and 12.4% of uncontrolled respondents did not see the relation between the treatment and hypertension control (P=.525). 31.1% believed to be well-controlled, but in fact was not.

    Full Text Available Pulmonary hypertension (PH is a potentially life-threatening condition arising from a wide variety of pathophysiologic mechanisms. Effective treatment requires a systematic diagnostic approach to identify all reversible mechanisms. Many of these mechanisms are relevant to those afflicted with obesity. The unique mechanisms of PH in the obese include obstructive sleep apnea, obesity hypoventilation syndrome, anorexigen use, cardiomyopathy of obesity, and pulmonary thromboembolic disease. Novel mechanisms of PH in the obese include endothelial dysfunction and hyperuricemia. A wide range of effective therapies exist to mitigate the disability of PH in the obese.

    Hypertension is a major public health problem due to its high prevalence and cardiovascular complications. Its treatment is aimed at reducing cardiovascular morbidity and mortality, its goal being to maintain blood pressure levels below 140/90 mm Hg. Hypertension control in Brazil is low, and nationwide rates are unknown. The objective of this review was to provide an overview on hypertension control in Brazil from publications in a database. We identified 45 publications. In population-based studies, the highest control rate (57.6%) was reported in a multicenter study in 100 municipalities and the city of São José do Rio Preto, São Paulo state (52.4%), while the lowest rates (around 10%) were identified in microregions of the Rio Grande do Sul state and in the city of Tubarão, Santa Catarina state. In conclusion, the studies assessed showed a wide variation in hypertension control rates. It is worth noting that the comparison between studies was a major limiting factor, because of the different methods used.

    Pulmonary arterial hypertension (PAH) is a complex disease with a high mortality. Management of this disease is underpinned by supportive and general therapies delivered by multidisciplinary teams in specialist centres. In recent years, a number of PAH-specific therapies have improved patient outcomes. This article will discuss the management of PAH in the context of relevant recently published studies in this area.

    Hypertension is a major public health problem due to its high prevalence and cardiovascular complications. Its treatment is aimed at reducing cardiovascular morbidity and mortality, its goal being to maintain blood pressure levels below 140/90 mm Hg. Hypertension control in Brazil is low, and nationwide rates are unknown. The objective of this review was to provide an overview on hypertension control in Brazil from publications in a database. We identified 45 publications. In population-based studies, the highest control rate (57.6%) was reported in a multicenter study in 100 municipalities and the city of São José do Rio Preto, São Paulo state (52.4%), while the lowest rates (around 10%) were identified in microregions of the Rio Grande do Sul state and in the city of Tubarão, Santa Catarina state. In conclusion, the studies assessed showed a wide variation in hypertension control rates. It is worth noting that the comparison between studies was a major limiting factor, because of the different methods used

    Cette étude à pour objectifs de décrire les pratiques des prescriptions, évaluer leur pertinence et leur conformité aux règles d’utilisations et étudier les facteurs susceptibles de les influencer. Il s’agit d’une étude transversale d’évaluation des prescriptions antibiotiques portant sur 105 patients réalisée au service des urgences médico-chirurgicales de l’H.M.I.Med V de Rabat sur une période d’un mois. Le recueil des données était fait à l’aide d’un questionnaire rapportant les données démographiques et anamnestiques, les antécédents, la notion d’allergie, les données spécifiques de l’examen clinique, les données para cliniques, la prescription détaillée de l’antibiotique. Les données récoltées ont été ensuite évaluées par un médecin référent, chargé d’indiquer les éventuelles erreurs de traitement. Parmi les infections ayant motivé la prescription des antibiotiques, les affections des systèmes respiratoires et urinaires étaient au premier rang, les familles d’antibiotiques les plus couramment employées sont les pénicillines, les quinolones et les céphalosporines. 74 prescriptions soit (70,5%) étaient à la fois pertinentes et conformes contre 9 prescriptions soit (8,6%) justifiées mais non pertinentes et 6 prescriptions soit (5,7%) étaient jugées injustifiées par le médecin référent par absence d’infection. Les évaluations des pratiques médicales sont rarement menées dans les établissements de santé; c’est dans ce cadre que nous avons voulu nous inscrire en produisant cette étude afin d’améliorer la pertinence de nos prescriptions antibiotiques et d’optimiser leur conformité aux différentes recommandations.

    Full Text Available Background/Aims: The ET system might be involved in the pathogenesis of hypertensive disorders during pregnancy. The objective is to analyse the impact of ET-1 in hypertensive pregnant women by a strict meta-analysis of published human clinical studies. Methods: Based on the principle of Cochrane systematic reviews, Cohort studies in PubMed (Medline, Google Scholar and China Biological Medicine Database (CBM-disc designed to identify the role of endothelin-1 (ET-1 in the pathophysiology of gestational hypertension and preeclampsia were screened. Review Manager Version 5.0 (Rev-Man 5.0 was applied for statistical analysis. Mean difference and 95% confidence interval (CI were shown in inverse variance (IV fixed-effects model or IV random-effects model. Results: Sixteen published cohort studies including 1739 hypertensive cases and 409 controls were used in the meta-analysis. ET-1 plasma concentrations were higher in hypertensive pregnant women as compared to the controls (mean difference between groups: 19.02 [15.60~22.44], P < 0.00001,. These finding were driven by severity of hypertension and/or degree of proteinuria. Conclusion: Plasma ET-1 concentrations are elevated in hypertensive disorders during human pregnancy. In particular women with preeclampsia (hypertensive pregnant women with proteinuria have substantially elevated plasma ET-1 concentration as compared to pregnant women with normal blood pressure.

    2016-12-01

    Diuretics have long been used for the treatment of hypertension. Thiazide diuretics are the most commonly prescribed diuretics for hypertension, but other classes of diuretics may be useful in alternative circumstances. Although diuretics are no longer considered the preferred agent for treatment of hypertension in adults and children, they remain acceptable first-line options. Diuretics effectively decrease blood pressure in hypertensive patients, and in adults with hypertension reduce the risk of adverse cardiovascular outcomes. Because of varied pharmacokinetic and pharmacodynamic differences, chlorthalidone may be the preferred thiazide diuretic in the treatment of primary hypertension. Other types of diuretics (e.g., loop, potassium sparing) may be useful for the treatment of hypertension related to chronic kidney disease (CKD) and other varied conditions. Common side effects of thiazides are mostly dose-related and involve electrolyte and metabolic abnormalities.

  8. [Hypertension in women (contraception and menopause].

    Science.gov (United States)

    Beaufils, M

    2000-11-01

    There are three circumstances where hypertension develops specifically in women: oral contraception, pregnancy, and menopause. Oral contraception usually shifts the blood pressure moderately upwards, but hypertension appears in less than 5% of women. Still it may (rarely) be very severe. Hypertension is poorly related to the dosage of the estrogenic compound, but rather to the nature and dosage of the progestive part. This hypertension does not significantly increase the cardiovascular risk of these women. The role of menopause itself in the trigging of hypertension remains uncertain. It seems however that confounding factors such as age, body weight, sodium balance and so on explain the increased incidence of hypertension after menopause. The latter is also associated with an increase of cardiovascular risk, which requires adequate treatment. Hormone replacement therapy is not contra-indicated, even in hypertensive patients.

  9. Chronic Management of Hypertension after Stroke: The Role of Ambulatory Blood Pressure Monitoring

    Hypertension is the most important potentially reversible risk factor for stroke in all age groups; high blood pressure (BP) is also associated with increased risk of recurrent stroke in patients who have already had an ischemic or hemorrhagic event. Twenty-four hour ambulatory BP monitoring (ABPM) has become an important tool for improving the diagnosis and management of hypertension, and is increasingly used to assess patients with hypertension. Nevertheless, although ABPM devices are increasingly used for assessment of hypertension, their value in the chronic management of hypertension in patients with stroke has not been systematically studied. In fact, among large-scale randomized trials for secondary stroke prevention, only the Morbidity and Mortality After Stroke, Eprosartan Compared With Nitrendipine for Secondary Prevention trial included 24-hour ABPM. ABPM has demonstrated chronic disruption of the circadian rhythm of BP after acute phase of stroke and has shown higher sensitivity compared to office BP in evaluating the effectiveness of antihypertensive treatment among stroke survivors. High 24-hour BP is an independent predictor for cerebrovascular events, brain microbleeds, and subsequent development of dementia. Nevertheless, although stroke care guidelines endorse the importance of hypertension management, the specific role of ABPM among stroke survivors after the acute phase of disease has not been established. Further studies are needed to clarify whether routine application of ABPM among these patients should be recommended. PMID:26687120

    Cushing's syndrome is associated with increased mortality, mainly due to cardiovascular complications, which are sustained by the common development of systemic arterial hypertension and metabolic syndrome, which partially persist after the disease remission. Cardiovascular diseases and hypertension associated with endogenous hypercortisolism reveal underexplored peculiarities. The use of exogenous corticosteroids also impacts on hypertension and cardiovascular system, especially after prolonged treatment. The mechanisms involved in the development of hypertension differ, whether glucocorticoid excess is acute or chronic, and the source endogenous or exogenous, introducing inconsistencies among published studies. The pleiotropic effects of glucocorticoids and the overlap of the several regulatory mechanisms controlling blood pressure suggest that a rigorous comparison of in-vivo and in-vitro studies is necessary to draw reliable conclusions. This review, developed during the first ‘Altogether to Beat Cushing's syndrome’ workshop held in Capri in 2012, evaluates the most important peculiarities of hypertension associated with CS, with a particular focus on its pathophysiology. A critical appraisal of most significant animal and human studies is compared with a systematic review of the few available clinical trials. A special attention is dedicated to the description of the clinical features and cardiovascular damage secondary to glucocorticoid excess. On the basis of the consensus reached during the workshop, a pathophysiology-oriented therapeutic algorithm has been developed and it could serve as a first attempt to rationalize the treatment of hypertension in Cushing's syndrome.

    The potential impact of employment on maternal health, particularly in relation to gestational hypertension and pre-eclampsia, has been subject to research. However, there is limited evidence on associations between shift work and long working hours on the incidence of these conditions. To evaluate potential associations between maternal shift work and long working hours during pregnancy and gestational hypertension or pre-eclampsia. Multistage stratified systematic sampling was used to recruit 24 200 post-partum women from the Taiwan national birth registration database in 2005. Subjects underwent home interview 6 months after their deliveries by structured questionnaire to obtain characteristics of maternal employment and potential confounders. Diagnosis of gestational hypertension and pre-eclampsia was obtained from the birth registration. There was no association between employment status and gestational hypertension or pre-eclampsia. Also, no significant association between gestational hypertension or pre-eclampsia and maternal shift work or long working hours during pregnancy was found in all or primiparous women. There was no convincing evidence that maternal shift work or long working hours had a higher risk of gestational hypertension or pre-eclampsia. However, further research is warranted to confirm these negative findings.

    Full Text Available Abstract Background Hypertension is a global health issue and is currently increasing at rapid pace in South Asian countries including Bangladesh. Although, some studies on hypertension have been conducted in Bangladesh, there is a lack of scientific evidence in the adult student population that was missing from the previous and recent national cross-sectional studies. Moreover, the specific risk factors of hypertension in the Bangladeshi adults still need to be investigated. This study was conducted to estimate hypertension prevalence among adult students in Bangladesh and to test the hypothesis of Luke et al. (Hypertension 43:555–560, 2004 that basal metabolic rate (BMR and blood pressure are positively associated independent of body size. Method The data was collected on 184 adult university students (118 female and 66 male in Dhaka, Bangladesh. Anthropometric, BMR details and an average of at least two blood pressure measurements were obtained. Hypertension was defined by a systolic blood pressure (SBP ≥ 140 mmHg and/or, diastolic blood pressure (DBP ≥ 90 mmHg. Results Overall, 6.5% of participants had hypertension with significantly (p < 0.001 higher prevalence in male (12.1% than in the female (3.4% students. Age and BMI showed positive and significant correlation with hypertension among the students. When adjusted for body mass index (BMI, as well as other potentially confounding variables such as age, sex, smoking status and degree of urbanization, BMR was positively correlated with SBP and DBP (p < 0.001. Thus, higher BMR is associated with SBP and DBP; this is opposite the well documented inverse relationship between physical activity and blood pressure. If the influence of BMR on blood pressure is confirmed, the systematically elevated BMR might be an important predictor that can explain relatively high blood pressure and hypertension in humans. Conclusion This study reports the prevalence and associated risk factors

    Full Text Available Hypertension is one of the most common cardiovascular diseases during pregnancy. Primary hyperaldosteronism (PHA is the most frequent endocrinological, secondary cause of hypertension, rarely diagnosed in pregnant women. In the available literature about 50 cases of PHA in pregnant women have been described. PHA is often a cause of resistant hypertension. PHA can cause life-threatening complications both for the pregnant woman and the fetus. Diagnosis of PHA in pregnancy is difficult due to the antagonistic effect of progesterone on aldosterone, physiological increase of aldosterone release during gestation and frequent normokalaemic clinical course. Typical pharmacological treatment of PHA is limited due to the anti‑androgenic effect of spironolactone, lack of data concerning the safety of eplerenone and limited access to amiloride in Poland. Surgical treatment is a therapeutic option only in early pregnancy. This paper presents the current state of knowledge on diagnostic methods and treatment of PHA in pregnant women and a systematic review of cases described in the literature.

    Cerebral hyperperfusion syndrome is a preventable cause of stroke after carotid endarterectomy (CEA). It manifests as headache, seizures, hemiparesis or coma due to raised intracranial pressure or intracerebral haemorrhage (ICH). There is currently no consensus on whether to control blood pressure, blood pressure thresholds associated with cerebral hyperperfusion syndrome, choice of anti-hypertensive agent(s) or duration of treatment. A systematic review of the PubMed database (1963-2010) was performed using appropriate search terms according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. A total of 36 studies were identified as fitting a priori inclusion criteria. Following CEA, the incidence of severe hypertension was 19%, that of cerebral hyperperfusion 1% and ICH 0.5%. The postoperative mean systolic blood pressure of patients, who went on to develop cerebral hyperperfusion syndrome, was 164 mmHg (95% confidence interval (CI) 150-178 mmHg) and the cumulative incidence of cases rose appreciably above a postoperative systolic blood pressure of 150 mmHg. The mean systolic blood pressure of cerebral hyperperfusion cases was 189 mmHg (95% CI 183-196 mmHg) at presentation. The incidence of cerebral hyperperfusion in the first week was 92% with a median time to presentation of 5 days (interquartile range (IQR) 3-6 days). 36% of patients presented with seizures 31% with hemiparesis and 33% with both. The proportion of patients with severe hypertension was significantly higher in cases than in post-CEA controls (p hypertension as a risk factor for ICH. There is currently level-3 evidence for the prevention of ICH through control of postoperative blood pressure. From the available data, we suggest a definition for cerebral hyperperfusion syndrome, blood pressure thresholds, duration of monitoring and a postoperative blood pressure control strategy for validation in a prospective study. The implications of this are that one in

    Masked hypertension, defined as non-elevated clinic blood pressure and elevated out-of-clinic blood pressure may be an intermediary stage in the progression from normotension to hypertension. We examined the associations of out-of-clinic blood pressure and masked hypertension using ambulatory blood pressure monitoring with incident clinic hypertension in the Jackson Heart Study, a prospective cohort of African Americans. Analyses included 317 participants with clinic blood pressure hypertension was defined as mean daytime blood pressure ≥135/85mmHg; masked nighttime hypertension as mean nighttime blood pressure ≥120/70mmHg; and masked 24-hour hypertension as mean 24-hour blood pressure ≥130/80mmHg. Incident clinic hypertension, assessed at study visits in 2005–2008 and 2009–2012, was defined as the first visit with clinic systolic/diastolic blood pressure ≥140/90mmHg or antihypertensive medication use. During a median follow-up of 8.1 years, there were 187 (59.0%) incident cases of clinic hypertension. Clinic hypertension developed in 79.2% and 42.2% of participants with and without any masked hypertension, 85.7% and 50.4% with and without masked daytime hypertension, 79.9% and 43.7% with and without masked nighttime hypertension and 85.7% and 48.2% with and without masked 24-hour hypertension, respectively. Multivariable-adjusted hazard ratios (95% CI) of incident clinic hypertension for any masked hypertension and masked daytime, nighttime, and 24-hour hypertension were 2.13 (1.51–3.02), 1.79 (1.24–2.60), 2.22 (1.58–3.12), and 1.91 (1.32–2.75), respectively. These findings suggest that ambulatory blood pressure monitoring can identify African Americans at increased risk for developing clinic hypertension. PMID:27185746

    Bortolotto Luiz Aparecido

    2003-01-01

    Full Text Available Two cases are reported as follows: 1 1 female patient with accelerated-malignant hypertension secondary to an aldosterone-producing adrenal adenoma; and 2 1 female patient with adrenal adenoma, severe hypertension, and hypertensive encephalopathy. This association is a rare clinical finding, and malignant hypertension may modify the hormonal characteristic of primary aldosteronism, making its diagnosis more difficult. The diagnosis of primary aldosteronism should be considered in patients with malignant hypertension or hypertensive encephalopathy if persistent hypokalemia occurs. Identification of primary aldosteronism is of paramount importance for the patient's evolution, because the surgical treatment makes the prognosis more favorable.

    Stress factors, especially high levels of occupational stress, are associated with hypertension. Several so-called psychological techniques have been applied to hypertension: biofeedback, relaxation techniques (Schultz' autogenic training, Jacobson's progressive relaxation), transcendental meditation, and cognitive behavioral techniques for stress management. Randomized studies show that the best results come from cognitive behavioral methods, whether or not they include relaxation techniques. Other forms of psychotherapy (such as psychoanalysis) may be useful, although their benefits for blood pressure have not been tested in controlled trials. Patients should be informed about the personal benefits they may obtain from psychological treatment. Indications are hyperreactivity to stress, high levels of occupational stress, and difficulty in tolerating or complying with antihypertensive drugs.

    The behavior of blood pressure under hypoxic conditions depends on individual factors, altitude and duration of stay at altitude. While most humans are normotensive at higher altitudes, a few will react with moderate hypertension or hypotension. Excessive elevation of arterial blood pressure is not even to be expected below 4,000 m. Rather, several weeks' stay at higher altitude will decrease systolic and diastolic blood pressure at rest as well as during physical exertion. A high-altitude treatment for rehabilitation purposes at moderate altitude may be recommended for patients with cardio-circulatory disorders. Improvements can last several months even after returning to accustomed altitudes. Furthermore, endurance-trained hypertensive patients with pharmacologically controlled arterial blood pressure might be able to participate in mountain treks without additional health risk.
