May Measurement Month 2018: an analysis of blood pressure screening results from Sudan.

To raise awareness of high blood pressure (BP) levels and associated risk factors among the Sudanese population. A cross-sectional study was conducted in six Sudanese states during the period May-August 2018. The study area included public indoor and outdoor areas, institutes, and service facilities. A questionnaire for collecting the data was employed including demographic data, along with three consecutive BP measurements. Data were collected by trained volunteers. Hypertension (HTN) was defined as a systolic blood pressure ≥140 mmHg or a diastolic blood pressure ≥90 mmHg based on the mean of the second and third measurements, or in those on antihypertensive medication. The current study indicated a high prevalence of HTN (28.2%) among 40 779 participants and a low level of awareness (20.7%) amongst these participants. Of all, 18.2% of hypertensive participants were on medication and of these, 54.6% were controlled. Of all hypertensives, only 9.9% were controlled. Further action needs to be taken by all stakeholders for raising awareness and increasing screening provision of HTN, which are essential for the development of national health policies for control and management of HTN in Sudan.

Intravenous and Inhaled Milrinone in Adult Cardiac Surgery Patients: A Pairwise and Network Meta-Analysis.

OBJECTIVE: To summarize the evidence on the hemodynamic, echocardiographic, and clinical effects of inhaled and intravenous milrinone (iMil and IvMil) in adult cardiac surgery patients. DESIGN: Systematic review, pairwise and network meta-analysis. SETTING: Multi-institutional. PARTICIPANTS: Adult cardiac surgery patients. INTERVENTIONS: Comparison between iMil and IvMil versus other agents or placebo. MEASUREMENTS AND MAIN RESULTS: The primary endpoints were mean pulmonary artery pressure (MPAP) and peripheral vascular resistance (PVR). Secondary endpoints included the following: (1) mean arterial pressure, heart rate, and cardiac index (CI); (2) echocardiographic data; and (3) clinical outcomes. Random model, leave-one-out-analysis, and meta-regression were used. Thirty studies (6 iMil and 24 IvMil) were included for a total of 1,438 patients (194 iMil and 521 IvMil). IvMil was associated with a lower MPAP, lower PVR, and higher CI compared to placebo (standardized mean difference [SMD] = -0.22 [95% CI = -0.48 to 0.05], SMD = -0.49 [95% CI = -0.71 to -0.27], and SMD = 0.94 [95% CI = 0.51 to 1.37]). No difference in any outcome was found between iMil and placebo. At network meta-analysis, significantly lower PVR and shorter hospital length of stay were found for IvMil compared to iMil (SMD = -0.82 [95% CI = -1.53 to -0.10] and SMD = -0.50 [95% CI = -0.95 to -0.05], respectively). CONCLUSION: These results support the clinical use of IvMil in cardiac surgery patients. No evidence at present supports the adoption of iMil.

Early Versus Delayed Stroke After Cardiac Surgery: A Systematic Review and Meta-Analysis.

Background Although it is traditionally regarded as a single entity, perioperative stroke comprises 2 separate phenomena (early/intraoperative and delayed/postoperative stroke). We aimed to systematically evaluate incidence, risk factors, and clinical outcome of early and delayed stroke after cardiac surgery. Methods and Results A systematic review ( MEDLINE , EMBASE , Cochrane Library) was performed to identify all articles reporting early (on awakening from anesthesia) and delayed (after normal awakening from anesthesia) stroke after cardiac surgery. End points were pooled event rates of stroke and operative mortality and incident rate of late mortality. Thirty-six articles were included (174 969 patients). The pooled event rate for early stroke was 0.98% (95% CI 0.79% to 1.23%) and was 0.93% for delayed stoke (95% CI 0.77% to 1.11%; P=0.68). The pooled event rate of operative mortality was 28.8% (95% CI 17.6% to 43.4%) for early and 17.9% (95% CI 14.0% to 22.7%) for delayed stroke, compared with 2.4% (95% CI 1.9% to 3.1%) for patients without stroke ( P<0.001 for early versus delayed, and for perioperative stroke, early stroke, and delayed stroke versus no stroke). At a mean follow-up of 8.25 years, the incident rate of late mortality was 11.7% (95% CI 7.5% to 18.3%) for early and 9.4% (95% CI 5.9% to 14.9%) for delayed stroke, compared with 3.4% (95% CI 2.4% to 4.8%) in patients with no stroke. Meta-regression demonstrated that off-pump was inversely associated with early stroke (ß=-0.009, P=0.01), whereas previous stroke (ß=0.02, P<0.001) was associated with delayed stroke. Conclusions Early and delayed stroke after cardiac surgery have different risk factors and impacts on operative mortality as well as on long-term survival.
