Background
The effect of intracranial pressure (ICP) monitoring on mortality after severe traumatic brain injury (sTBI) remains unclear. We hypothesized that ICP monitoring would not be associated with improved survival in patients with sTBI.Methods
A retrospective analysis was performed on sTBI patients, defined as admission Glasgow Coma Scale score of 8 or less with intracranial hemorrhage. Patients who underwent ICP monitoring were compared with patients who did not. The primary outcome measure was inhospital mortality.Results
Of 123 sTBI patients meeting inclusion criteria, 40 (32.5%) underwent ICP monitoring. On bivariate and multivariate regression analyses, ICP monitoring was associated with decreased mortality (odds ratio = .32, 95% confidence interval = .10 to .99, P = .049). This finding persisted on propensity-adjusted analysis.Conclusions
ICP monitoring is associated with improved survival in adult patients with sTBI. In addition, significant variability exists in the use of ICP monitoring among patients with sTBI. 相似文献75.

The accuracy of blood pressure (BP) measuring devices is fundamental to good practice and scientific research. International guidelines on BP measurement are provided for clinicians who diagnose and treat patients with hypertension, clinical researchers who conduct trials on the efficacy of BP lowering drugs and interventional strategies, epidemiologists who conduct population surveys to determine the demographic consequences of hypertension on society, and researchers who perform meta‐analyses on published research to further influence the practice of medicine and the provision of resources. Although the outcomes of the endeavors of all these groups are dependent on the accuracy of BP measurements, the equipment is often of doubtful accuracy and the methodology of measurement is often poorly described and frequently not standardized. Thus, the fundamental element of hypertension evaluation has been largely ignored by both clinical practitioners and scientific researchers. Here, the authors briefly review the development of efforts to improve and validate the accuracy of BP measuring devices and highlight the deficiencies that persist. We conclude that, to protect the public from the serious consequences of inaccurate BP measurements, the following steps are required: (1) regulatory requirement for mandatory independent validation of all BP measuring devices using a universal protocol; (2) accreditation of laboratories for the performance of BP device validations; (3) online evaluation of validation studies with detection of protocol violations prior to publication of results; and (4) establishment of an independent scientific forum for the listing of accurate BP measuring devices. 相似文献

Hypertension is present in almost one‐quarter of women and one‐third of men in Korea. Although mortality rates from stroke and myocardial infarction (MI) appear to be decreasing, stroke is a more common cause of cardiovascular death than MI. This may be due to better control of hypertension, but national control rates have remained stable for more than a decade (at about 45%). Korean Society of Hypertension guidelines have recommended the use of home blood pressure monitoring (HBPM) since 2007, but a recent survey suggests that physicians have concerns about the accuracy of HBPM devices. Nevertheless, use of HBPM is indispensable to monitoring and achieving blood pressure (BP) control. Current diagnostic and treatment thresholds and recommendations are based on Asian consensus document guidance. Use of dual combination antihypertensive therapy is slightly more common than use of monotherapy in Korea, while triple combination therapy is used less often. Angiotensin receptor blockers and calcium channel blockers are the most popular choices for antihypertensive therapy and are the most widely used combination. HBPM plays an important role in evaluating and monitoring BP, particularly in Asians. Individualized cardiovascular risk assessment and better BP control are required to prevent cardiovascular diseases, but there is a need for local evidence relating to optimal BP thresholds and targets. 相似文献

Ambulatory blood pressure monitoring (ABPM) can measure 24‐hour blood pressure (BP), including nocturnal BP and diurnal variations. This feature of ABPM could be of value in Asian populations for preventing cardiovascular events. However, no study has yet investigated regarding the use of ABPM in actual clinical settings in Asian countries/regions. In this study, 11 experts from 11 countries/regions were asked to answer questionnaires regarding the use of ABPM. We found that its use was very limited in primary care settings and almost exclusively available in referral settings. The indications of ABPM in actual clinical settings were largely similar to those of home BP monitoring (HBPM), that is, diagnosis of white‐coat or masked hypertension and more accurate BP measurement for borderline clinic BP. Other interesting indications, such as nighttime BP patterns, including non‐dipper BP, morning BP surge, and BP variability, were hardly adopted in daily clinical practice. The use of ABPM as treatment guidance for detecting treated but uncontrolled hypertension in the Asian countries/regions didn't seem to be common. The barrier to the use of ABPM was primarily its availability; in referral centers, patient reluctance owing to discomfort or sleep disturbance was the most frequent barrier. ABPM use was significantly more economical when it was reimbursed by public insurance. To facilitate ABPM use, more simplified indications and protocols to minimize discomfort should be sought. For the time being, HBPM could be a reasonable alternative. 相似文献

Introduction
Hypertension is highly prevalent in black South Africans in which morbidity and mortality from stroke are on the increase. Elevated blood pressure and haemostatic markers can induce changes in blood rheology and endothelial function which could result in a procoagulant state that increases the risk for cerebrovascular disease. Information about the coagulation and fibrinolytic systems of people from African descent are limited. We therefore, investigated the haemostatic profile and its relationships with blood pressure in black South Africans.Materials and methods
We measured ambulatory blood pressure and haemostatic markers of 201 black and 208 white school teachers. The haemostatic markers included measurements representing coagulation and fibrinolysis (von Willebrand factor, fibrinogen, plasminogen activator inhibitor-1, fibrin D-dimer and clot lysis time).Results
Black participants displayed significantly higher blood pressure, von Willebrand factor, fibrinogen, plasminogen activator inhibitor-1 and D-dimer levels and longer clot lysis times (p ≤ 0.001). Single, partial and multiple regression analyses showed that systolic (p ≤ 0.011) and diastolic blood pressure (p = 0.010) correlated positively with D-dimer in black participants, while systolic (p ≤ 0.001) and daytime diastolic blood pressure (p = 0.011) correlated negatively with clot lysis time in white participants.Conclusion
The black population had a more prothrombotic profile, with higher levels of coagulation markers and inhibited fibrinolysis, than the white study participants. The positive association between blood pressure and elevated D-dimer in the blacks may contribute to the high prevalence of hypertension and related increased cardiovascular and cerebrovascular risk in this group. 相似文献80.

Background: Despite confirmed reduced physical activity (PA) after stroke in various stages of recovery, the type of activities stroke patients executed and the time spent at different activity levels have not been sufficiently verified with stroke-validated assessment tools.Design: Observational study.Objective: To determine PA of sub-acute stroke patients hospitalized in a rehabilitation centre (HOS) compared to chronic home-living stroke patients (HOM) using objective and self-reported measures during 2 weekdays and 1 weekend day.Methods: Fifteen HOS and 15 HOM patients wore a Sense Wear Pro 2 accelerometer (METs*minutes/24 h) and a knee-worn pedometer Yamax Digi Walker SW 200 (steps) and filled in a coded activity diary (kcal/24 h; METs*minutes/24 h) during three consecutive days.Results: In HOM significantly more steps (stepstotal HOM = 18722.6 ± 10063.6; stepstotal HOS = 7097.8 ± 5850.5) and higher energy expenditure (EE) levels (EEtotal HOM = 7759.34 ± 2243.04; EEtotal HOS = 5860.15 ± 1412.78) were measured. In this group less moderate activity (≥3–6 ≤ METs) was performed on a weekday (pday1 = 0.006; pday2 = 0.027) and in total (p = 0.037). Few therapy hours (physical, occupational and speech therapy, and psychological support) were provided in HOM compared to HOS (p < 0.001). Vigorous activities were only seen in HOM. In both groups few patients executed sport activities.Conclusions: In HOM significantly more steps were performed and higher EE values were measured. However, participation in moderate activities and time spent on therapy were less in HOM. Evaluating PA with quantitative measures is feasible in both chronic home-living and sub-acute hospitalized patients with stroke. 相似文献
