99% of heart attack, stroke, heart failure cases linked to preventable risk factors

Cardiovascular diseases, such as heart failure, heart attack, and stroke, are the leading causes of death around the world. Previous research shows there are a number of modifiable lifestyle factors that can help a person lower their risk for heart disease. A new study reports that more than 99% of people who experienced a heart attack, heart failure, or stroke had at least one of four major cardiovascular risk factors above healthy levels beforehand. Scientists also found that of the four major cardiovascular disease risk factors studied, high blood pressure was the most common issue.

Rheumatoid arthritis silently starts years before pain, study finds

Rheumatoid arthritis is a chronic autoimmune condition that cannot be cured but can be treated to prevent its progression. Individuals at risk of developing rheumatoid arthritis can be identified 3-5 years prior to symptom onset based on autoantibody levels, but only 30-60% of individuals expressing these autoantibodies develop this condition. A recent study has identified changes in the immune profile or signature of individuals at risk for developing rheumatoid arthritis as they progress in the disease. These findings could help with detecting rheumatoid arthritis early and developing more effective preemptive therapies.

Coffee drinkers have a lower risk of liver diseases, evidence shows

Coffee can promote liver health, according to a new analysis of decades of existing data. In addition to affirming proposed connections between coffee and a healthier liver, the new review identifies the molecular pathways through which such connections may occur. As a result of the compounds it contains, coffee can support liver health in at least five different and significant ways. The effects of coffee are dose-dependent, says the review, and the ability to tolerate its consumption is highly individualized.

Even small amounts of alcohol may increase dementia risk, study finds

Alcohol consumption, particularly heavy alcohol use, is linked to many health conditions, including an increased risk of dementia. However, studies have suggested that consuming small amounts of alcohol might actually decrease the risk of developing dementia. Now, a study has found that low alcohol consumption may not have the suggested protective effect. The study, which used both observational and genetic analysis, suggests that any alcohol consumption may increase a person’s risk of dementia, with the risk increasing as alcohol intake increases.

Exercise, healthy diet can help older adults regain 'optimal well-being' within 3 years

The global population of older adults ages 60 and over is expected to jump from 12% in 2015 to 22% by 2050. Past studies show there are several lifestyle factors that can have a negative impact on how healthy older adults may age. A new study says that it may be possible for older adults to regain their optimal well-being by making healthy lifestyle choices, even at age 60 and older.

interventions may help reduce cognitive decline

While it’s not uncommon for people to experience problems with thinking and remembering with aging, moderate to severe cognitive decline is not a common aging experience. While not all cases of mild cognitive impairment lead to dementia, about 10-20% of cases do. For this reason, clinicians emphasize the importance of following a healthy lifestyle to help keep one’s brain healthy as one ages. Among these interventions are following the MIND diet, a moderate to high-intensity exercise program, and engaging socially.

Could taking cocoa extract supplements daily prevent age-related heart disease?

In a new study, researchers examined whether cocoa extract supplements have an impact on age-related inflammation, which is linked to heart disease and other chronic illnesses. The researchers found that 500 mg of daily cocoa extract supplements slowed increases in a key marker of inflammation. These benefits were strongest in individuals with higher baseline or existing inflammation at the start.

Keto may aid weight loss but lead to high cholesterol, mouse study suggests

Ketogenic diets that provide most of the daily calorie intake from fats have gained considerable attention as a lifestyle intervention for managing obesity and diabetes. Despite its popularity and effectiveness in promoting short-term weight loss, some human and animal studies suggest an adverse impact of a keto diet on metabolic health. A new long-term study conducted in mice now shows that a keto diet causes an increase in blood lipid (fat) levels, excessive fat storage in the liver, and impaired glucose regulation. These results raise concerns about the use of a keto diet for the management of obesity and diabetes and underscore the need for a cautionary approach.

Vision loss due to aging may be remedied by new eye drops

Researchers estimate that about 1.8 billion people around the world live with presbyopia, a farsightedness condition that can appear as a person grows older. More recent treatment options for presbyopia are eye drops such as Vuity, which uses pilocarpine hydrochloride. A new study found that a new eye drop using both pilocarpine plus diclofenac helped study participants improve their ability to read up close.
