Chained to health ministry, Peruvians protest mining pollution

Parents of sick children who live near one of Peru`s oldest mining pits camped out in front of the health ministry in Lima for an eighth day on Thursday, demanding help to deal with the impact of decades of mining pollution. Dozens of residents of Simon Bolivar, a district in the city of Cerro de Pasco in the Peruvian Andes, travelled to Lima to press the government to declare a health emergency and build a regional hospital specializing in exposure to heavy metals. More than 40 percent of the area`s children who were tested in a 2012 study had dangerously high levels of lead in their blood, according to a screening of some 2,700 children by regional health authorities

Postpartum haemorrhage: Cheap lifesaver 'cuts deaths by a third'

Every year, 100,000 women die from massive bleeding in the moments after giving birth. Now an international study published by the Lancet suggests that tranexamic acid could cut that number by a third. It acts by stopping blood clots from breaking down to make it easier for the body to stem bleeding

Hypertension is the silent killer disease spreading across an Africa that isn’t ready

A survey in four countries: Burkina Faso, Ghana, Kenya and South Africa, looked at both rural areas and the peri-urban settings in the cities of Nairobi and Johannesburg, and showed that hypertension is a critical health problem in Africa. There are stark differences in the prevalence, awareness and control of high blood pressure on the continent. Ultimately there is a need for regionally tailored intervention

SGLT2 inhibitors help reduce high blood pressure, study reports

A group of oral medications given to people with type 2 diabetes have been found to help reduce high blood pressure. A research team from China, South Africa and Iran looked at 43 random trials which had involved 22,428 people. As well as high blood pressure, they examined how SGLT2 inhibitors affected health markers including cholesterol and triglycerides. SGLT2 inhibitor therapy was shown to significantly reduce blood pressure throughout the studies

Heart healthy lifestyle tied to lower drug costs

People with heart disease spend a lot less on medications when they take steps to lower their risk of complications by doing things like getting enough exercise, avoiding cigarettes and keeping their blood pressure in check, a U.S. study suggests. For the study, researchers focused on adults diagnosed with the most common type of heart disease, atherosclerosis. When these patients did as much as they could to avoid so-called modifiable risk factors for heart disease - inactivity, obesity, smoking, high cholesterol, elevated blood pressure and diabetes - their total average annual pharmaceutical expenditures were $1,400, the study found. But patients who did little to modify these risk factors had total average annual pharmaceutical expenditures of $4,516

New Three-in-One Blood Test for Prostate Cancer

Scientists have developed a three-in-one blood test that could transform treatment of advanced prostate cancer through use of precision drugs designed to target mutations in the BRCA genes. By testing cancer DNA in the bloodstream, researchers found they could pick out which men with advanced prostate cancer were likely to benefit from treatment with PARP inhibitors. They also used the test to analyse DNA in the blood after treatment had started, so people who were not responding could be identified and switched to alternative therapy in as little as four to eight weeks

Daily aspirin behind more than 3,000 deaths a year, study suggests

Taking a daily aspirin is far more dangerous than was thought, causing more than 3,000 deaths a year, a major study suggests. The study by Oxford University found that those over the age of 75 who take the blood-thinning pills are ten times more likely than younger patients to suffer disabling or fatal bleeds. Researchers said patients of this age who have already suffered heart attacks or strokes should still take the daily tablet, but should also take an extra drug to reduce the risk of bleeding

How low to push blood sugar, and how to do it?

Growing evidence suggests that the method by which blood sugar is lowered may make a big difference in heart risk. That has raised a medical dilemma affecting tens of millions of people with type 2 diabetes — and for the doctors who treat them. At identical A1C levels, some drugs lowered risk, some did not change it — and some actually increased the chances of heart disease. Older and much cheaper diabetes medications, like metformin, have not been subjected to such tests, although they do have long and well established safety records. But whether they actually prevent heart problems is unknown

Lower-income U.S. adults haven't seen heart health gains

Heart health in the US has generally improved since the start of the 21st century, but not for adults living in poverty, a new study suggests. Between 1999 and 2014, high-income people had decreases in rates of high blood pressure, smoking and high risk for heart disease. The same wasn`t true for low-income people, however. The data shows that primary care and prevention is important for people with low incomes, researchers added

Sri Lanka`s cabinet on Wednesday approved to increase physical activities among school children and to provide opportunities to consume more healthy meals to prevent obesity, co-Cabinet Spokesperson, Gayantha Karunathilleke told journalists here in a weekly media briefing that around 59 percent of deaths in Sri Lanka were caused by non-communicable diseases such as heart diseases, diabetes, high blood pressure and cancers and majority of deceased were under the age of 60. As less physical activities are a main cause for these diseases, the proposal made by Health Minister Rajitha Senaratne to implement a program under the recommendations of the Ministry of Education for increasing physical activities among school children and to provide opportunities for school children to consume more healthy meals, was approved by the Cabinet of Ministers, Karunathilleke said

Pregnancy Complications Linked To Heart Disease Risk In Offspring

Children whose mothers experienced pregnancy complications were almost three times more likely to develop heart disease, complications of pregnancy, such as high blood pressure and infections, are linked to a heightened risk of early coronary heart disease in the young adult offspring, according to research published in Heart Asia. More than 600 million people live in Southeast Asia, most of whom are under the age of 65. But rates of premature deaths attributable to non-communicable diseases are high, with one in three occurring before the age of 60

Tiny blood vessel damage tied to depression among older adults

Damage to the microvascular system, often caused by high blood pressure or diabetes and made worse by smoking is tied to an increased risk of depression among people aged 40 years and older, researchers have found. Depending on how microvascular dysfunction was measured in the various studies, it increased the risk of depression by up to 58%, according to a report in JAMA Psychiatry. The theory is that blood vessel damage disrupts communication in areas of the brain important for mood control

Genetic mutations study validate new strategy for reducing cholesterol

According to a recent study, an injectable antibody can be really helpful for lowering blood lipids and thereby potentially preventing coronary artery disease and other conditions caused by the build-up of fats, cholesterol. This new study targets a protein called ANGPTL3, a regulator of enzymes that clears triglycerides and other fat molecules from the blood. The scientists studied ANGPTL3 in both humans and mice. They found that blocking ANGPTL3 activity with an investigative injectable antibody, known as evinacumab, reduced triglycerides by up to 76 percent and lowered LDL cholesterol 23 percent in human study participants and largely reversed signs of atherosclerosis in mouse models

Diabetes drug may work by changing gut bacteria makeup

Researchers looked into the most successful treatment for type 2 diabetes and found that it seems to work by changing the makeup of the gut bacteria. Metformin is commonly prescribed to help people with type 2 diabetes control their blood sugar. It is believed to work by reducing the amount of glucose made in the liver, which in turn lowers blood sugar levels. Researchers discovered that the drug seems to encourage the growth of strains of bacteria called Akkermansia and Bifidobacterium and this seems to influence blood sugar levels. Researchers believe more investigation of these findings may be necessary

Britain to hold inquiry into contaminated blood scandal which killed 2,400

Britain will hold a public inquiry into contaminated blood supplied to patients in the National Health Service which killed at least 2,400 people. During the 1970s and 1980s, blood products supplied to the NHS were contaminated with viruses such as HIV or hepatitis C and infected thousands of people with haemophilia or other disorders. A report by lawmakers in 2015 said the Department of Health estimated that more than 30,000 people might have been infected with hepatitis C between 1970 and 1991 when Britain imported some blood products from the United States but just 6,000 had been identified. A further 1,500 were infected with HIV between 1978 and 1985

Parirenyatwa bemoans high blood user fees

Health and Child Care Minister David Parirenyatwa has said blood user fees continue to be a thorn in the flesh of the government, as many patients at public health institutions cannot afford to access the product due to high costs. “To the surgeon, blood products are key and many times doctors have had to cancel patients for theatre because of failure to secure blood, which most times is a prerequisite for the anaesthetists to put patients to sleep,” he said. Parirenyatwa said in 2016, the blood user fees were reduced from $135 a unit to $100 for government hospitals and from $160 to $120 for the private hospitals, which was a huge improvement

World Blood Donor Day 2017: Shocking facts on India’s illegal blood industry

In India there is a huge shortage of blood, despite the large number of blood donation camps. As per a 2012 report by WHO, only 9m blood units are available annually whereas demand is 12m. Blood is illegally sold at a higher price most of the time and not given to patients on the basis of medical conditions, more like an auction. Some hospitals extract plasma out of blood and sell it on to pharma companies. There’s a thriving black market for getting money for donations and selling blood. Blood farms exist where poor people are forced to donate up to 12 times a month, and there is little testing meaning blood is prone to disease and infections

Scarcity of safe, inexpensive blood fast-tracking deaths

Despite the establishment of the National Blood Transfusion Service (NBTS) – a national blood system designed to make blood affordable and adequately available at all times, millions across Nigeria still toil very hard to procure increasingly expensive blood. Nigeria needs about 1.8 million units of blood yearly to save people from dying during emergency medical care. This is a far cry from the 51,433 units provided by NBTS in 2016, according Dr. Toyin Smith. Blood obtained from other medical facilities, mainly through commercial blood donors and family replacement methods, were about 1.4 million units. This takes the total figure obtained from NBTS and other facilities to 1.5m units

New flu test: One drop of blood could save your life

Researchers have developed a world-first blood test to predict which flu patients will develop potentially life-threatening secondary infections that demand urgent medical treatment. The High-risk Influenza Screen Test (HIST) measures `an early warning signal` released by the patient`s body into their blood to `kick start` their immune system`s fight against the infection. The test, developed by Dr Benjamin Tang -- a doctor from the Department of Intensive Care Medicine, Nepean Hospital and medical researcher at Westmead Institute for Medical Research -- needs only a single drop of blood and a few hours to predict, with 91 percent accuracy, which influenza patients will develop potentially deadly secondary infections, such as pneumonia
