Fifty-eight percent of deaths among people with type 2 diabetes are due to cardiovascular events, a leading Mexican expert has said.

“Patients who live with this disease have a greater risk of premature death or disability derived from cardiovascular events,” Hector Sanchez Mijangos, President of the Mexican Diabetes Federation, told Efe news.

The specialist said that the high glucose levels associated with diabetes damage blood vessels, resulting in problems with blood pressure and vision, joint pain and other maladies.

Data from the World Health Organization indicate that more 442 million people suffer from type 2 diabetes.

Mexico’s Health Secretariat has found that while roughly 13 million inhabitants of the Aztec nation are living with diabetes, only half of those afflicted know they have the disease.

In 2015 alone, according to Mijangos, there were more than 98,000 premature deaths in Mexico related to diabetes and the average age of those who died was 66.7 years old.

“This is regrettable, because these people could have lived roughly another 15 years,” he said.

According to the 2012 National Health and Nutrition Survey, only 25 percent of Mexicans suffering with diabetes are managing their condition adequately.

That figure illustrates “why our greatest challenge continues to be access and adherence to treatment”, Mijangos said.

To improve treatment options, Mexican health authorities in January issued an approval for the use of canagliflozin, a drug that helps reduce the amount of blood glucose reabsorbed by the kidneys, which in turns causes more glucose to be eliminated through urination.

“With this medicine, a person can lose 100 milligrams of glucose per day as well as about 400 kilocalories (4,000 calories) a day, which also helps with weight loss,” Mijangos said.

The medicine likewise helps lower the amount of sodium in the body and reduce triglyceride levels and blood pressure.

A scientific trial involving more than 10,000 patients worldwide showed that when combined with conventional treatment, canagliflozin can reduce the incidence of cardiovascular events by up to 18 percent. (IANS)

Drugs That Treat Arthritis in Dogs Can Kill Cancer Cells: Study

Drugs for diabetes, inflammation, alcoholism — and even for treating arthritis in dogs — can also kill cancer cells in the lab, according to a new health news and study.

The researchers systematically analysed thousands of already developed drug compounds and found nearly 50 that have previously unrecognised anti-cancer activity.

The findings, which also revealed novel drug mechanisms and targets, suggest a possible way to accelerate the development of new cancer drugs or repurpose existing drugs to treat cancer.

“We thought we’d be lucky if we found even a single compound with anti-cancer properties, but we were surprised to find so many,” said study researcher Todd Golub from Harvard University in the US.

The study, published in the journal Nature Cancer, yet to employ the Broad’s Drug Repurposing Hub, a collection that currently comprises more than 6,000 existing drugs and compounds that are either FDA-approved or have been proven safe in clinical trials (at the time of the study, the Hub contained 4,518 drugs).

Historically, scientists have stumbled upon new uses for a few existing medicines, such as the discovery of aspirin’s cardiovascular benefits.

“We created the repurposing hub to enable researchers to make these kinds of serendipitous discoveries in a more deliberate way,” said study first author Steven Corsello, from Dana-Farber Cancer Institute and founder of the Drug Repurposing Hub.

The researchers tested all the compounds in the Drug Repurposing Hub on 578 human cancer cell lines from the Broad’s Cancer Cell Line Encyclopedia (CCLE).

Using a molecular barcoding method known as PRISM, which was developed in the Golub lab, the researchers tagged each cell line with a DNA barcode, allowing them to pool several cell lines together in each dish and more quickly conduct a larger experiment.

The team then exposed each pool of barcoded cells to a single compound from the repurposing library, and measured the survival rate of the cancer cells.

They found nearly 50 non-cancer drugs — including those initially developed to lower cholesterol or reduce inflammation — that killed some cancer cells while leaving others alone.

Some of the compounds killed cancer cells in unexpected ways.

“Most existing cancer drugs work by blocking proteins, but we’re finding that compounds can act through other mechanisms,” said Corsello.

Some of the four-dozen drugs researchers identified appear to act not by inhibiting a protein but by activating a protein or stabilising a protein-protein interaction.

For example, the team found that nearly a dozen non-oncology drugs killed cancer cells that express a protein called PDE3A by stabilising the interaction between PDE3A and another protein called SLFN12 — a previously unknown mechanism for some of these drugs.

These unexpected drug mechanisms were easier to find using the study’s cell-based approach, which measures cell survival, than through traditional non-cell-based high-throughput screening methods, Corsello said.

Most of the non-oncology drugs that killed cancer cells in the study did so by interacting with a previously unrecognized molecular target.

For example, the anti-inflammatory drug tepoxalin, originally developed for use in people but approved for treating osteoarthritis in dogs, killed cancer cells by hitting an unknown target in cells that overexpress the protein MDR1, which commonly drives resistance to chemotherapy drugs. (IANS)
