Hypertension is a major risk factor for heart disease and stroke, and it is also the leading cause of premature death and disability in individuals. Previous reports have shown that the prevalence of hypertension is growing in low- and middle-income countries, and high incomes The country is in a stable or declining trend, but researchers are not aware of the prevalence of hypertension in the world.
In this study, the researchers analyzed the past 131 studies, using gender and age-specific hypertension prevalence to calculate the area in which high-pressure adult individuals live, and the researchers also conducted global Estimated; the researchers found that:
1) In 2010, 31.1% (1.39 billion) of the world's population suffered from high blood pressure, 28.5% (349 million) of patients lived in high-income countries, and 31.5% (1.04 billion) of patients lived in low- and middle-income Countries; 2) The prevalence of hypertension from 2000 to 2010 decreased by 2.6% in high-income countries, and increased by 7.7% in low- and middle-income countries; 3) in high-income countries, from 2000 to 2010 The corresponding situation in the year has been significantly improved, the awareness of hypertension has increased from 58.2% to 67.0%; the treatment rate has increased from 44.5% to 55.6%, and the control of patients with hypertension has increased from 17.9% to 28.4%; In low-income and middle-income countries, from 2000 to 2010, there was only a slight improvement in the awareness of hypertension, from 32.3% to 37.9%; the treatment rate increased from 24.9% to 29.0%. The rate of control over high blood pressure has dropped from 8.4% to 7.7%.
Jiang He, MD, said that the increase in the elderly population, urbanization and the accompanying multiple unhealthy lifestyle factors, such as high-salt, high-fat, high-calorie diets and lack of exercise, play a role in the prevalence of hypertension in low- and middle-income countries. Importantly, health care systems are often overwhelmed in these countries, and they do not have the resources to selectively treat and control high blood pressure; in addition, because high blood pressure patients are generally asymptomatic, many low- and middle-income countries People do not regularly check or take medication.
The researchers pointed out that this study can represent the majority of the world's population, but more than half of the world's countries do not have data on the prevalence of hypertension, so there seems to be some uncertainty in the prevalence of hypertension in these regions; Dr. Katherine T. Mills said that in low- and middle-income countries, high blood pressure needs to be placed in priority public health so that cardiovascular disease, kidney disease and related treatment costs can be more effectively prevented; Multi-country cooperation is needed to develop innovative and effective control procedures to prevent and control the occurrence and prevalence of hypertension.
Polyhydroxyalkanoates (PHAs) comprise a group of natural biodegradable polyesters that are synthesized by microorganisms. However, several disadvantages limit their competition with traditional synthetic plastics or their application as ideal biomaterials. These disadvantages include their poor mechanical properties, high production cost, limited functionalities, incompatibility with conventional thermal processing techniques and susceptibility to thermal degradation. To circumvent these drawbacks, PHAs need to be modified to ensure improved performance in specific applications. In this review, well-established modification methods of PHAs are summarized and discussed. The improved properties of PHA that blends with natural raw materials or other biodegradable polymers, including starch, cellulose derivatives, lignin, poly(lactic acid), polycaprolactone and different PHA-type blends, are summarized. The functionalization of PHAs by chemical modification is described with respect to two important synthesis approaches: block copolymerization and graft copolymerization. The expanded utilization of the modified PHAs as engineering materials and the biomedical significance in different areas are also addressed.
