High Levels of Iron Protect Arteries from Clogging but It’s not All That Good

A new study from Imperial College London suggests that higher levels of iron may cut the risk of clogged arteries. On the other hand, they are linked to a higher risk of blood clots.High Levels of Iron Protect Arteries from Clogging but It's not All That Good

Within the scope of the study, the scientists used genetic data from 500,000 people to explore links between iron levels and more than 900 conditions.

Lead and corresponding author of the study Dr. Dipender Gill comments: “However, getting the right amount of iron in the body is a fine balance — too little can lead to anaemia, but too much can lead to a range of problems including liver damage.”

Air Pollution Linked to Higher Risk of Coronary Artery Calcification

A new study of Chinese adults finds a link between air pollution and a higher risk of developing atherosclerosis, or coronary artery calcification, as well as death from heart disease.Air Pollution Linked to Higher Risk of Coronary Artery Calcification

To investigate the influence of air pollution, a team of researchers analyzed data on 8,867 Chinese people whose age varied from 25 to 92 years. All of them had suspected coronary heart disease and were recruited between 2015 and 2017.

The analysis showed that for each nitrogen dioxide increase of 20 μg/m3, the risk of having a high coronary artery calcium score increased by 24.5 per cent, and for each 30 μg/m3, the risk increased by 27.2 per cent.

The lead author Meng Wang says: “This study may provide evidence that coronary atherosclerosis is a pathological pathway through which air pollution exposure increases risk of death from coronary heart disease.”

Having a Close Relative with Alzheimer’s Disease May Impair Cognition

According to recent research from the Translational Genomics Research Institute, US, having a close relative with Alzheimer’s disease may affect cognition and learning.Having a Close Relative with Alzheimer’s Disease May Impair Cognition

During the study, the total amount of 59,571 participants completed online questionnaires including questions about their sex, educational level, age, language, country, overall health, and family history of the Alzheimer’s disease.

After the participants answered all the necessary questions, they were asked to memorize 12-word pairs. After that, they had to retest their memory with the new pairs of words filling in the matching words missing.

The analysis of the collected data showed that people with a close relative with the condition (a parent or a sibling) matched 2.5 fewer word pairs compared to people without a family history of the condition.

Sugary Drinks May Increase the Risk of Developing Cancer

According to a new observational study from France, consumption of sugary drinks, including 100% fruit juices, may increase the risk of cancer.Sugary Drinks May Increase the Risk of Developing Cancer

A team of researchers analyzed data from 101,257 French adults whose median age was 42 from the NutriNet-Santé study to check the association between the consumption of sugary drinks and various forms of cancer.

The drinks included sugar-sweetened beverages such as soft drinks, syrups, fruit drinks, 100% fruit juices without added sugar, milk-based sugary drinks, sports drinks, and energy drinks.

Having analyzed the available data, the researchers concluded that a daily increase of 100 ml in the intake of this type of drinks associated with the higher risk of developing cancer by 18%, and the breast cancer risk raise by 22%.

Scientists Devised a Blood Test to Predict Breast Cancer Recurrence

A new study from the US looks at the body’s antitumor inflammatory response to devise a blood test that can be used to predict the chances of breast cancer recurrence.Scientists Devised a Blood Test to Predict Breast Cancer Recurrence

For their research, a team of scientists recruited 40 breast cancer survivors and followed them for a period of 4 years, on average. They also used an additional sample of 38 breast cancer survivors to attempt to replicate their findings from the previous group.

The senior author of the study Dr. Peter P. Lee, chair of the Department of Immuno-Oncology at the City of Hope Comprehensive Cancer Center, in Duarte, says: “This is the first success [in] linking a solid tumor with blood biomarkers — an indicator of whether a patient will remain in remission.”
