WHO | Health system strengthening and hypertension awareness

IntroductionMethodsResultsDiscussionCardiovascular and other noncommunicable diseases are currently responsible for two thirds of global mortality.1,2 Universal health coverage may allow great improvements in the control of such diseases3,4 but the best way to achieve such coverage, especially in low- and middle-income countries, remains unclear.5 Hypertension is a consistent and independent risk factor for cardiovascular and kidney diseases and stroke.6 It is also very common, its global prevalence being about 40%.2 Hypertension, which plays a part in approximately 55% of the global mortality caused by cardiovascular diseases and in 7% of all disability-adjusted life years,7 could be managed at fairly low cost, even in resource-poor settings.8–10 In the developed world, more than 80% of people with hypertension are aware of their condition and receiving treatment.11–13 However, the health systems in most developing countries fail to detect and manage hypertension effectively.14,15 In China, the overall prevalence of...Get price

Optimal Systolic Blood Pressure Levels for Primary Prevention

IntroductionMethodsResultsDiscussionPerspectivesAcknowledgmentsHypertension is an important public health challenge, affecting over 1 billion adults worldwide (≈300 million in China).1,2 The Global Burden of Disease, Injuries, and Risk Factor study in 2013 reported that high systolic blood pressure (SBP) was one of the leading risk factors for death and disability-adjusted life-years in most countries.3 Several randomized trials support the use of blood pressure (BP)–lowering drugs to reduce the risk of cardiovascular disease (CVD). A meta-analysis of 61 prospective studies, including 1 million adults with no previous vascular disease at baseline who were subsequently followed for ≈14 years, showed a linear relationship between SBP and cardiovascular risk down to 115 mm Hg.4 However, although the most appropriate targets for SBP lowering have long been debated in high-risk patients,5–8 such as those with diabetes mellitus or a history of CVD, or renal disease, few studies9–11 have focused on optimal SBP levels in hypertensive adults without suc...Get price

Air Travel - Centers for Disease Control and Prevention

Preflight Medical ConsiderationsBarotrauma During FlightVentilation and Air QualityIn-Flight Medical EmergenciesIn-Flight Transmission of Communicable DiseasesInformation For AircrewBibliographyDuring flight, the aircraft cabin pressure is usually maintained at the equivalent of 6,000–8,000 ft (1,829–2,438 m) above sea level. Most healthy travelers will not notice any effects. However, for travelers with cardiopulmonary diseases (especially those who normally require supplemental oxygen), cerebrovascular disease, anemia, or sickle cell disease, conditions in an aircraft can exacerbate underlying medical conditions. Aircraft cabin air is typically dry, usually 10%–20% humidity, which can cause dryness of the mucous membranes of the eyes and airways. The new Boeing 787 and Airbus A 350 have improved the cabin environment: a greater number of temperature zones, a higher humidity of 25%, a faster time to refresh cabin air, lower ambient noise, and multiple shades of LED lighting. These, along with a cabin air pressure equivalent to an altitude of only 2,000 ft, should provide more comfort and ease jet lag.
