Global study predicts increases in cancer cases and deaths among men, with widening disparities based on age and countries’ economic status

Results indicate the need for efforts to improve cancer outcomes equitably.

2024-08-12

(Press-News.org) In an analysis of 30 cancer types among men, investigators uncovered substantial disparities in cancer cases and deaths by age and countries’ economic status—disparities that are projected to widen by 2050. The study is published by Wiley online in CANCER, a peer-reviewed journal of the American Cancer Society.

Men face higher rates of cancer and cancer-related deaths than women, likely due to various factors including lower participation in cancer prevention activities; underuse of screening and treatment options; increased exposure to cancer risk factors such as smoking, alcohol consumption, and occupational exposure to carcinogens; and biological differences.

To assess the burden of cancer in men of different ages and living in different regions of the world, investigators analyzed 2022 information from the Global Cancer Observatory, which encompasses national-level estimates for cancer cases and deaths for 185 countries/territories worldwide. The projected cancer cases and deaths in 2050 were derived through demographic projections: the researchers multiplied the 2022 age-specific rates with their corresponding population projections for 2050.

In 2022, poorer survival was observed among older men; for rare cancer types such as pancreatic cancer; and in countries with low human development index, which measures health, education, and standard of living.

Between 2022 and 2050, cancer cases are projected to increase from 10.3 million to 19 million, an 84% increase. Deaths are projected to increase from 5.4 million to 10.5 million, a 93% increase, with a greater than two-fold increase among men aged 65+ years and for countries/territories with low and medium human development index.

The research reveals an urgent need to address these trends and ensure equity in cancer prevention and care among men globally.

“A national and international collaboration, as well as a coordinated multisectoral approach, are essential to improve current cancer outcomes and to reverse the anticipated rise in cancer burden by 2050. Implementing and expanding universal health coverage and expanding health infrastructure and establishing publicly funded medical schools and scholarships for training medical and public health staff can improve cancer care and equity,” said lead author Habtamu Mellie Bizuayehu, PhD, of the University of Queensland, in Australia. “Emphasis should be placed on low and medium human development index countries with high unmet cancer service needs despite a significant cancer burden.

Dr. Bizuayehu added that improving access to and use of cancer prevention, screening, diagnosis, and treatment options, especially for older men, could also improve cancer outcomes and equity.

USC study: Drug protects against air pollution-related Alzheimer’s signs in mice

2024-08-12

A new study led by the USC Leonard Davis School of Gerontology shows how feeding mice a drug called GSM-15606 provided protection against air pollution-related increases in proteins linked to Alzheimer’s disease. Senior author Caleb Finch, USC University Professor and holder of the ARCO/William F. Kieschnick Chair in the Neurobiology of Aging at the USC Leonard Davis School, has studied air pollution’s effects on the brain for several years, especially the consequences of exposure to fine particulates found in pollution from automobiles, factories and more. ...

Mild Cognitive Impairment could be going unreported in rural areas of west Michigan, study suggests

2024-08-12

Grand Rapids, Mich., Aug. 12, 2024 – Corewell Health™ and Michigan State University researchers are the first in the state to use de-identified electronic health records of more than 1.5 million patients to analyze incidence rates and risk factors of mild cognitive impairment, or MCI, in rural and urban areas in West Michigan. Results showed that many cases could be going undetected among those living in rural communities in the area, and researchers now will use the findings to develop AI tools that can detect MCI earlier among patients across the country. The retrospective study, which included 10 years of historical patient ...

Eco-conscious fashionistas hampered by geographical barriers to return clothing

2024-08-12

Eco-conscious consumers are not well-served by clothing companies claiming green credentials, as shoppers’ location has a major impact on the effectiveness of clothing return schemes, a new study reveals. Environmental circular economy initiatives for activewear companies are limited by where firms and consumers are located, preventing them from being fully effective. The clothing industry is one of the biggest global polluters, with fast fashion companies creating cheap clothing that gets thrown away after one or two uses and ends up in landfill. According to the European ...

Fern becomes first in suborder to be classed as “independent gametophyte”

2024-08-10

Tokyo, Japan – Researchers from Tokyo Metropolitan University have discovered that the fern Hymenasplenium murakami-hatanakae can become independent gametophytes i.e. live for long periods without a spore-producing sporophyte. They collected specimens from Izu-Oshima Island, Japan, and used DNA analysis to show that this Aspleniineae fern, a suborder encompassing thirty percent of ferns on the planet, was part of this rare class. Studying the species further promises to reveal more about how ferns diversify and adapt. The “alternation of generations” in plants and algae is the intricate cycle by which they reproduce. Each ...

As temperatures break records, many are unaware of symptoms of heat-related illnesses

2024-08-09

PHILADELPHIA – With NASA data showing that July 22, 2024, was the hottest day on record and indications that July may have been the hottest month, an Annenberg Public Policy Center survey conducted in mid-July found that most people know three of the symptoms of a heat-related illness but do not know the location of their nearest cooling center. At the same time, increasing numbers of people think that heat waves are becoming more frequent and intense and affecting their daily activities. Knowledge of cooling centers in the case of extreme heat Although the locations of cooling centers, or indoor air-conditioned facilities such as libraries, ...
