Do non-statin cholesterol-lowering drugs affect liver cancer risk?

Like statins, cholesterol absorption inhibitors are linked with a lower risk of developing liver cancer.

2024-07-29

(Press-News.org) Past studies have suggested that taking cholesterol-lowering statin drugs may lower individuals’ risk of developing liver cancer. In a new study of non-statin cholesterol-lowering medications, one type was linked to lower risks of liver cancer. The findings are published by Wiley online in CANCER, a peer-reviewed journal of the American Cancer Society.

Cholesterol absorption inhibitors, bile acid sequestrants, fibrates, niacin, and omega-3 fatty acids are types of non-statin cholesterol-lowering medications prescribed to manage cholesterol and lipid levels. The different classes of drugs work in different ways. A team led by Katherine A. McGlynn, PhD, MPH, of the National Cancer Institute, looked for associations between these five types of non-statin cholesterol-lowering medications and risk of liver cancer, the sixth most commonly occurring cancer globally and the third leading cause of cancer mortality.

The investigators used information from the Clinical Practice Research Datalink (CPRD), a primary care database that covers approximately 7% of the United Kingdom population. Their analysis included 3,719 liver cancer cases and 14,876 matched controls without cancer. Additional matches were also made based on individuals’ type 2 diabetes and chronic liver disease status.

Use of cholesterol absorption inhibitors was associated with 31% lower odds of liver cancer risk in the overall analysis. These medications were also linked with a lower risk of liver cancer in analyses based on diabetes and liver disease status. The study also confirmed that statins were associated with 35% lower odds of liver cancer.

No associations with liver cancer risk were observed for fibrates, omega-3 fatty acids, or niacin. While bile acid sequestrant use was associated with higher odds of liver cancer risk in the overall analysis, the results of analyses based on diabetes and liver disease status were inconsistent, suggesting that replication of these observations is important.

“As few studies have examined the effects of non-statin cholesterol-lowering drugs on liver cancer risk, the results of our study require replication in other populations. If our findings are confirmed in other studies, however, our results may inform liver cancer prevention research,” said Dr. McGlynn.

Every minute counts: rapid and accurate prediction model for cardiac arrest treatment

2024-07-29

When it comes to treating cardiac arrest, acting quickly can mean the difference between life and death. Researchers from Osaka Metropolitan University have developed a new scoring model, using only prehospital resuscitation data, that accurately predicts neurological outcomes of patients with out-of-hospital cardiac arrest (OHCA). This model potentially allows healthcare providers to make quick and accurate decisions upon the patient’s arrival at the hospital, ultimately improving patient care and resource allocation. Their findings were published in Resuscitation on May 31. Cardiac arrest can lead to death within minutes. OHCA is not uncommon and often results ...

Hypertensive disorders of pregnancy increasing in Canada

2024-07-29

In Canada, rates of hypertensive disorders of pregnancy (HDP) have increased, but the good news is there has been a decline in some related health conditions, according to new research published in CMAJ (Canadian Medical Association Journal) https://www.cmaj.ca/lookup/doi/10.1503/cmaj.231547. Hypertensive disorders of pregnancy include chronic hypertension (high blood pressure), gestational hypertension, and preeclampsia or eclampsia. These disorders affect 5%–10% of pregnancies worldwide, and cause more than 50 000 maternal deaths and 500 000 deaths in fetuses and infants ...

Is free genetic testing really free?

2024-07-29

Free genetic testing, offered partially or fully subsidized by industry, may have trade-offs, and health systems in Canada must carefully weigh potential clinical, ethical, and legal considerations to protect patient data, authors argue in a CMAJ (Canadian Medical Association Journal) commentary https://www.cmaj.ca/lookup/doi/10.1503/cmaj.231588. “Near- and long-term expansion in no-cost testing and industry partnership in genetics, with patient data as the commodity, is likely,” writes Kirsten ...

Health: Short-term vegan diet associated with reductions in biological age estimates

2024-07-29

Eating a vegan diet for eight weeks is associated with reductions in biological age estimations based on levels of DNA methylation — a type of chemical modification of DNA (known as an epigenetic modification) that alters gene expression but not DNA itself. Previous research has reported that increased DNA methylation levels are associated with ageing. The findings, which are based on a small randomised controlled trial of 21 pairs of adult identical twins, are published in BMC Medicine. Varun Dwaraka, Christopher ...

Evidence-based information combats misleading and false claims on the internet and social media about the anti-Mullerian hormone test

2024-07-29

Researchers in Australia have found that when women are given accurate information about a test that indicates the number of eggs in their ovaries, they have less interest in taking the test compared to women who viewed information available online. The researchers initiated the study, which is published today (Monday) in Human Reproduction [1], one of the world’s leading reproductive medicine journals, because of the large amount of misleading and incorrect information promoted to women about the anti-Mullerian hormone (AMH) test on websites, including fertility clinic websites, and via social media. AMH ...

Steel industry’s net zero drive could make lower-grade iron ore viable

2024-07-29

A decarbonised steel industry that includes carbon dioxide removal techniques in its net zero arsenal could use lower-grade iron ore, according to a new study. Steel accounts for 5-8% of carbon dioxide emissions globally. Its total emissions have risen over the past decade, largely due to increased demand. The International Energy Agency has stated that, without innovation, the scope to limit emissions is ‘limited’. Therefore, the commercialisation of new zero-emission production processes is critical. Innovative ...

Plasma phosphorylated tau 217 and Aβ42/40 to predict early brain Aβ accumulation in people without cognitive impairment

2024-07-28

About The Study: The results of this cohort study suggest that combining plasma p-tau217 and Aβ42/40 levels could be useful for predicting development of Aβ pathology in people with early stages of subthreshold Aβ accumulation. These biomarkers might thus facilitate screening of participants for future primary prevention trials.

MRI signature of α-synuclein pathology in asymptomatic stages and a memory clinic population

2024-07-28

About The Study: In this cohort study, seed amplification assays (SAA) α-syn+ was consistently associated with nucleus basalis of Meynert (NBM) atrophy already during asymptomatic stages. Further, in memory clinic cognitively impaired populations, SAA α-syn+ was associated with NBM atrophy, which partially mediated α-syn–induced attention/executive impairment.

Blood biomarkers to detect Alzheimer disease in primary care and secondary care

2024-07-28

About The Study: The amyloid probability score 2 (APS2) blood test and percentage of p-tau217 alone had high diagnostic accuracy for identifying Alzheimer disease among individuals with cognitive symptoms in primary and secondary care using predefined cutoff values. Future studies should evaluate how the use of blood tests for these biomarkers influences clinical care.

Changes in Alzheimer disease blood biomarkers and associations with incident all-cause dementia

2024-07-28

About The Study: Plasma biomarkers of Alzheimer disease (AD) neuropathology, neuronal injury, and astrogliosis increase with age and are associated with known dementia risk factors. AD-specific biomarkers’ association with dementia starts in midlife whereas late-life measures of AD, neuronal injury, and astrogliosis biomarkers are all associated with dementia.
