Carbon Dioxide, Climate Change Reduce Availability Of Nutrients

One of the biggest challenges to reducing hunger and under nutrition around the world is to produce foods; that provide not only enough calories but also make enough necessary nutrients widely available. New research finds that, over the next 30 years, climate change; and increasing carbon dioxide (CO2) could significantly reduce the availability of critical…

Uranium Toxicity May Be Causing High Rates Of Obesity And Diabetes

Kuwait has some of the highest rates of obesity and diabetes in the world; and scientists don’t know why. This question addressed by Dr. Max Goodson, Emeritus Professor at the Forsyth Institute. However, uranium is a potent renal toxin; with the element accumulating in calcified tissues, livers, and kidneys as a result of both natural…

Lower Than Expected Risk Of Bone Density Decline With Truvada PrEP

Researchers have shown that among users of pre-exposure prophylaxis (PrEP); to prevent against AIDS that includes tenofovir (Truvada), those with daily use very high adherence had only about a 1% average decrease in bone density; in the spine and a 0.5% decline in the hip. The study findings and the implications for the lower than…

Opioid Overdose Deaths

Higher Risk Of Opioid Overdose Deaths In Countries of U.S.

In a study of more than 3,000 counties across the U.S., the researchers found that residents of 412 counties are at least twice; as likely to be at high risk for opioid overdose deaths; and to lack providers who can deliver medications to treat opioid use disorder. States with among the most high-risk counties include:…

Air Pollution

Study Finds Association Between Air Pollution, Coronary Atherosclerosis

Researchers found that long-term exposure to particulate matter and nitrogen dioxide due to air pollution; as well as proximity to vehicular traffic, were associated with severity of coronary artery calcium, or the buildup of plaque in the artery walls. The study was conducted on 8,867 Chinese adults aged 25 to 92. But the findings, published in…

Lung

Air Pollution: Aging Of The Lung And Chronic Lung Disease Risk

Ambient air pollution increases the risk of respiratory mortality; but evidence for impacts on lung function and chronic obstructive pulmonary disease (COPD) is less well establish. However, the aim was to evaluate whether ambient air pollution; is associate with lung function and COPD; and explore potential vulnerability factors. They use UK Biobank data on 3 03 887…

Black Lung Disease

What Causes Black Lung Disease Among Coal Miners

Researchers believe the higher rates of more severe lung disease may be due to greater exposure to silica; likely as a byproduct of going after ever-narrowing coal seams that require cutting through more rock to reach. But silica dust is much more toxic to the lungs; but little is known about its contribution to black…

Female Fertility

Female Fertility Can Be Marked By Air Pollution

Adverse effects of higher level of air pollution is found from large scale study; ovarian reserve, a term widely adopted to reflect the number of resting follicles in the ovary and thus a marker of potential female fertility. Behind the study lay emerging evidence that many environmental chemicals; as well as natural and artificial components…

Air Pollution

Life Expectancy Of Children Is Decreased By Air Pollution

The “mortality burden” of a lifetime of breathing toxic air has been calculate for one of the UK’s largest cities; Birmingham, by a team from King’s College London. Air pollution may decrease as much as 7 months off the life expectancy of children; who live in congested cities, research suggests. Poor health from air pollution…

Air Pollution May Offset Health Benefits Of Walkable Cities

Higher density equals more walking. “This is an issue of life and death.” But a new Canadian study finds that air pollution can offset these benefits. One of the authors of the study, Nicholas Howell, is interview for St. Michael’s Hospital, where the research was done. Sprawl, in effect, kills. Less density equals more driving.…

Incarceration And Economic Hardship: Drug Overdose Deaths In US

Growing rates of incarceration in the USA since the mid-1970s may be linked with a rise in drug overdose deaths; and may exacerbate the harmful health effects of economic hardship; according to an observational study involving 2,640 US counties between 1983 and 2014, published in The Lancet Public Health journal. Major increases in admissions rates…
