Recent Longevity News for the week ending 7/21/21

Coffee Won't Upset Your Heartbeat. It Might Even Calm It - WebMD, 12/9/21 - "most people can enjoy their morning joe or afternoon diet cola free from worry -- caffeine doesn't seem to increase most people's risk of arrhythmias ... In fact, results indicate that every additional cup of coffee a person drinks daily might lower their risk of arrhythmia by about 3% on average"

Common medication used to reduce cholesterol levels may reduce COVID-19 severity - Science Daily, 7/15/21 - "the use of statins or an anti-hypertension medication was associated with a 32 percent lower risk of death among COVID-19 inpatients with a history of cardiovascular disease or hypertension"

Metformin Use May Curb BCC Risk - Medscape, 7/15/21 - "In addition to general anticarcinogenic effects, metformin has also been shown to directly inhibit the sonic hedgehog pathway, a key pathway in basal cell carcinoma (BCC) pathogenesis ... Overall, metformin use was associated with a significantly lower risk of developing BCC, compared with nonuse (adjusted odds ratio, 0.71" - See metformin at ReliableRX.

Does Optimal Iron Absorption Include Vitamin C? - Medscape, 7/15/21 - "Less frequent administration of iron supplements (every other day) is as effective as more frequent administration, with less GI symptoms. Also, adding vitamin C does not appear to improve absorption of iron supplements" - See vitamin C products at Amazon.com and iHerb.com.

Stop Using Neutrogena and Aveeno Spray Sunscreen, J&J Warns - WebMD, 7/15/21 - "Consumers should stop using certain brands of spray-on sunscreen products made by Johnson & Johnson. The company has issued a voluntary recall after finding low levels of benzene, a known cancer-causing agent, in some samples"

Antibiotics in early life could affect brain development - Science Daily, 7/14/21 - "The study compared mice that were exposed to low-dose penicillin in utero or immediately after birth to those that were not exposed. They found that mice given penicillin experienced substantial changes in their intestinal microbiota and had altered gene expression in the frontal cortex and amygdala, two key areas in the brain responsible for the development of memory as well as fear and stress responses"

Compound derived from turmeric essential oil has neuroprotective properties - Science Daily, 7/14/21 - "a component derived from turmeric essential oil, aromatic turmerone (ar-turmerone), and its derivatives act directly on dopaminergic nerves to create a neuroprotective effect on tissue cultures of a Parkinson's disease model. This appears to be due to enhanced cellular antioxidant potency from the activation of Nrf2. The researchers believe that the ar-turmerone derivatives identified in this study can be used as new therapeutic agents for Parkinson's disease" - See turmeric essential oil at Amazon.com.

New study links moderate alcohol use with higher cancer risk - Science Daily, 7/14/21 - "Alcohol causes cancer in numerous ways ... The main mechanism of how alcohol causes cancer is through impairing DNA repair. Additional pathways include chronic alcohol consumption resulting in liver cirrhosis, and alcohol leading to a dysregulation of sex hormones, leading to breast cancer. Alcohol also increases the risk of head and neck cancer for smokers as it increases the absorption of carcinogens from tobacco"

Whole Grains May Lower Risk of Heart Disease in Older Adults - WebMD, 7/13/21 - "An analysis of over 3,000 middle- and older-age adults over many years found that those who ate at least three servings of whole grains daily had smaller increases in blood sugar levels, blood pressure, and waist size, compared to those who ate less than one-half serving per day ... For each 4-year interval, the researchers found that waist size increased by about one-half inch in people who had high whole-grain intake, compared to 1 inch in those who had low intake. Average increases in blood pressure and blood sugar levels were also lower in high-intake adults" -

Athletes Face Twice the Odds for A-Fib - WebMD, 7/13/21 - "Overall, athletes had about a 2.5 times higher risk of a-fib than non-athletes. But when the researchers focused on participants without heart disease risk factors (such as type 2 diabetes and high blood pressure), they found that athletes had nearly four times the risk of a-fib compared to non-athletes"

More Than Just a Hill of Beans: The Health Effects of Coffee - Medscape, 7/12/21 - ""The consensus around coffee has evolved over time from being concerned about increased risks of cancer and cardiovascular disease in the 1970s and '80s, to being quite confident of no overall increase in risk of noncommunicable diseases, and a good likelihood of benefit for cardiometabolic risk," he said ... As Willet and colleagues noted in a recent review paper in the New England Journal of Medicine, habitual coffee consumption (around 3 to 5 cups a day) has now been consistently linked to the prevention of several chronic conditions, acting on various organ systems as both a potent delivery system for caffeine and a dietary cornerstone with plenty of uniquely advantageous properties of its own ... Here's a look at some of the more convincing data of coffee's proposed benefits" -

Testosterone Replacement Shows CV Benefit in Hypogonadal Men - Medscape, 7/12/21 - "The latest results come from a study of 805 men with hypogonadism from Germany and Qatar who were followed for nearly a decade. For those who received parenteral testosterone 1000 mg every 12 weeks, there were improvements in classical cardiovascular risk factors, such as obesity, lipid level, and inflammatory markers, whereas among those who chose not to take testosterone (control patients), all of these factors worsened ... In addition, there were only 16 deaths among patients in the TRT group, and none of the deaths were from myocardial infarction (MI) or stroke ... In contrast, there were 74 deaths among the control patients, as well as 70 cases of MI and 59 strokes"

No Evidence Muscle Relaxers Ease Low Back Pain - WebMD, 7/9/21 - "But while the studies suggested that muscle relaxants might ease pain in the short term, "on average, the effect is probably too small to be important," said study author James McAuley. "And most patients wouldn't be able to feel any difference in their pain compared to taking a placebo, or sugar pill.""

After Metformin, Which Drug Makes the GRADE? - Medscape, 7/9/21 - "Patients treated with liraglutide and sitagliptin had more weight loss than those treated with glimepiride. All participants treated with glargine had stable weight over time ... GRADE didn't include an SGLT2 inhibitor. One of the reasons for that is that GRADE was started before SGLT2 inhibitors were even approved in the United States. This is a very long-term trial that looked at outcomes in a low-risk population over time, and we unfortunately don't have the comparison between SGLT2 inhibitors and the medications included in GRADE"

Meta-analysis Supports Cardiovascular Benefits of EPA - Medscape, 7/8/21 - "The meta-analysis of 38 randomized controlled trials found that omega-3 fatty acids improved cardiovascular outcomes, with a greater reduction in cardiovascular risk in studies of EPA alone rather than of combined eicosapentaenoic plus docosahexaenoic (DHA) supplements" - See omega-3 supplements at Amazon.com and iHerb.

Stress May Turn Hair Gray, but Calm May Reverse It - Medscape, 7/8/21 - "They developed a mathematical model to predict what might happen to human hair over time and suggest there is a point in a person's life when stress can temporarily induce loss of color, but that can be reversed if tensions ease"

Many Generic Meds Cheaper at Costco Than Medicare - Medscape, 7/7/21 - "Medicare plan participants paid more than Costco members on nearly 53% of 90-day fills in 2018. On all 30- and 90-day prescription fills, Medicare plans overpaid 43% of the time, the University of Southern California (USC) researchers found"

Characterization of the Gut-Liver-Muscle Axis in Cirrhotic Patients With Sarcopenia - Medscape, 7/6/21 - "Alterations in the gut-liver-muscle axis are associated with sarcopenia in patients with cirrhosis. Detrimental but also compensatory functions are involved in this complex network" - See probiotic supplements at Amazon.com and iHerb.

  • NMN and NR: How These NAD+ Precursors Measure Up - elysiumhealth.com - "NMN is a precursor to NAD+, or nicotinamide adenine dinucleotide, meaning it becomes NAD+ through a series of chemical transformations ... However, NMN is like a large bed that movers are trying to get through a door: It doesn’t enter the cell easily. One way for NMN to enter the cell is for it to chemically transform into another molecule (called nicotinamide riboside, or NR) before it can enter the cell. NR has earned a name for itself as a highly efficient precursor to NAD+ and can enter the cell as is. NMN, meanwhile, sometimes becomes NR before entering the cell, where it chemically transforms back to NMN and then ultimately becomes NAD+"
  • What’s the Difference Between NAD+ and NADH? - Elysiumhealth.com - "When NAD+ is converted to NADH, it gains two things: First, a charged hydrogen molecule (H+) and next, two electrons. As electrons are negatively charged, the combination of the positively charged NAD+ and H+, coupled with two electrons, effectively cancel each other out and neutralize the resulting NADH molecule. This is why NADH does not have a "+" sign next to it. The charge of a molecule informs how it interacts with other molecules. For example, NADH can’t do what NAD+ does, and vice versa."
