Get Serious, Stop Wasting Time

Jack Thomas is an 82-year-old newspaperman who unexpectedly learned he would die soon. He wrote about it at The Boston Globe. RTWT. If you’re old, you may need a tissue handy, in case you get something in your eye. He’s a talented writer. A few out-of-order excerpts:

“After a week of injections, blood tests, X-rays, and a CAT scan, I have been diagnosed with cancer. It’s inoperable. Doctors say it will kill me within a time they measure not in years, but months.

“As the saying goes, fate has dealt me one from the bottom of the deck, and I am now condemned to confront the question that has plagued me for years: How does a person spend what he knows are his final months of life?

“Atop the list of things I’ll miss are the smiles and hugs every morning from my beautiful wife, Geraldine, the greatest blessing of my life. I hate the notion of an eternity without hearing laughter from my three children. And what about my 40 rose bushes? Who will nurture them? I cannot imagine an afterlife without the red of my America roses or the aroma of my yellow Julia Childs.

“We told each of the three children individually. John Patrick put his face in his hands, racked with sobs. After hanging up the telephone, Jennifer doubled over and wept until her dog, Rosie, approached to lick away the tears but not the melancholy. Faith explained over the telephone that, if I could see her, she was weeping and wondering how she could get along without her dad. Now, she is on the Internet every day, snorkeling for new research, new strategies, new medications. My wife cries every morning, then rolls up her sleeves and handles all doctor appointments and medication. Without her . . . I cannot imagine.

“Editing the final details of one’s life is like editing a story for the final time. It’s the last shot an editor has at making corrections, the last rewrite before the roll of the presses. It’s more painful than I anticipated to throw away files and paperwork that seemed critical to my survival just two weeks ago, and today, are all trash. Like the manual for the TV that broke down four years ago, and notebooks for stories that will never be written, and from former girlfriends, letters whose value will plummet the day I die. Filling wastebasket after wastebasket is a regrettable reminder that I have squandered much of my life on trivia.

“Unlike Roman Catholics, Jews, and atheists, we Episcopalians are very good at fence-sitting. We embrace all viewpoints, and as a result, we are as confused as the Unitarians.

“Does the intensity of a fatal illness clarify anything? Every day, I look at my wife’s beautiful face more admiringly, and in the garden, I do stare at the long row of blue hydrangeas with more appreciation than before. And the hundreds and hundreds of roses that bloomed this year were a greater joy than usual, not merely in their massive sprays of color, but also in their deep green foliage, the soft petals, the deep colors and the aromas that remind me of boyhood. As for the crises in Cuba and Haiti, however, and voting rights and the inexplicable stubbornness of Republicans who refuse to submit to an inoculation that might save their lives — on all those matters, no insights, no thunderbolts of discovery. I remai­­n as ignorant as ever.

“I’ll miss my homes in Cambridge and Falmouth. I’ll never again see the sun rise over the marsh off Vineyard Sound, never again see that little, yellow goldfinch that perched atop a hemlock outside my window from time to time so that both of us could watch the tide rise to cover the wetland.

“As death draws near, I feel the same uncomfortable transition I experienced when I was a teenager at Brantwood Camp in Peterborough, New Hampshire, packing up to go home after a grand summer. I’m not sure what awaits me when I get home, but this has certainly been an exciting experience. I had a loving family. I had a great job at the newspaper. I met fascinating people, and I saw myriad worldwide wonders. It’s been full of fun and laughter, too, a really good time.

“I just wish I could stay a little longer.”

If You Have Type 2 Diabetes, Coffee May Prolong Your Life

“Is the world shaking, or is it just me?”

Compared to no coffee-drinking, drinking four cups a day reduced overall death rate by 20%, reduced cardiovascular deaths by 40%, and reduced death rate form coronary artery disease by 30%. The study at hand was a meta-analysis involving over 80,000 folks with type 2 diabetes living in multiple studies and followed clinically for 5-20 years. “Cardiovascular deaths” are usually heart attacks, strokes, cardiac arrest, or heart failure.

I vaguely recall a study several decades ago linking coffee to pancreas cancer, one of the deadliest cancers. The research was subsequently discredited.

Is coffee as a drink considered “paleo”? It seems to have originated in Africa, which is considered the cradle of humanity. I’m not sure anybody knows when we started drinking it; maybe 14 centuries ago. It’s possible we chewed it as a stimulant even before that. Extant humans who’ve been drinking four cups a day for many years are unlikely to drop the habit even if it isn’t paleo.

From Nutrition, Metabolism & Cardiovascular Diseases:

Aims

To evaluate the long-term consequences of coffee drinking in patients with type 2 diabetes.

Data synthesis

PubMed, Scopus, and Web of Sciences were searched to November 2020 for prospective cohort studies evaluating the association of coffee drinking with risk of cardiovascular disease (CVD) and mortality in patients with type 2 diabetes. Two reviewers extracted data and rated the certainty of evidence using GRADE approach. Random-effects models were used to estimate the hazard ratios (HRs) and 95% CIs. Dose–response associations were modeled by a one-stage mixed-effects meta-analysis. Ten prospective cohort studies with 82,270 cases were included. Compared to those with no coffee consumption, the HRs for consumption of 4 cups/d were 0.79 (95%CI: 0.72, 0.87; n = 10 studies) for all-cause mortality, 0.60 (95%CI: 0.46, 0.79; n = 4) for CVD mortality, 0.68 (95%CI: 0.51, 0.91; n = 3) for coronary heart disease (CHD) mortality, 0.72 (95%CI: 0.54, 0.98; n = 2) for CHD, and 0.77 (95%CI: 0.61, 0.98; n = 2) for total CVD events. There was no significant association for cancer mortality and stroke. There was an inverse monotonic association between coffee drinking and all-cause and CVD mortality, and inverse linear association for CHD and total CVD events. The certainty of evidence was graded moderate for all-cause mortality, and low or very low for other outcomes.

Conclusions

Drinking coffee may be inversely associated with the risk of mortality in patients with type 2 diabetes. However, more research is needed considering type of coffee, sugar and cream added to coffee, and history of CVD to present more confident results.

High Blood Pressure: How Low Should You Go?

Not a bad monitor

First, remember that blood pressure is reported as two numbers: systolic and diastolic. E.g., 135/92. The first number is the systolic number. A systolic pressure goal of under 120 mmHg may be better than the traditional goal of under 140, at least if you’re “at increased risk for cardiovascular disease.” The study at hand excluded folks with diabetes or prior stroke.

We randomly assigned 9,361 participants who were at increased risk for cardiovascular disease but did not have diabetes or previous stroke to adhere to an intensive treatment target (systolic blood pressure, <120 mm Hg) or a standard treatment target (systolic blood pressure, <140 mm Hg). The primary outcome was a composite of myocardial infarction, other acute coronary syndromes, stroke, acute decompensated heart failure, or death from cardiovascular causes. Additional primary outcome events occurring through the end of the intervention period (August 20, 2015) were adjudicated after data lock for the primary analysis. We also analyzed post-trial observational follow-up data through July 29, 2016.

RESULTS

At a median of 3.33 years of follow-up, the rate of the primary outcome and all-cause mortality during the trial were significantly lower in the intensive-treatment group than in the standard-treatment group (rate of the primary outcome, 1.77% per year vs. 2.40% per year; hazard ratio, 0.73; 95% confidence interval [CI], 0.63 to 0.86; all-cause mortality, 1.06% per year vs. 1.41% per year; hazard ratio, 0.75; 95% CI, 0.61 to 0.92). Serious adverse events of hypotension, electrolyte abnormalities, acute kidney injury or failure, and syncope were significantly more frequent in the intensive-treatment group. When trial and post-trial follow-up data were combined (3.88 years in total), similar patterns were found for treatment benefit and adverse events; however, rates of heart failure no longer differed between the groups.

Is “evolutionary-concordance lifestyle” the new “paleo diet”?

From the March 6, 2021, European Journal of Nutrition:

Sedentary lifestyle NOT an option back then

Purpose:

Evolutionary discordance may contribute to the high burden of chronic disease-related mortality in modern industrialized nations. We aimed to investigate the associations of a 7-component, equal-weight, evolutionary-concordance lifestyle (ECL) score with all-cause and cause-specific mortality.

Methods:

Baseline data were collected in 2003-2007 from 17,465 United States participants in the prospective Reasons for Geographic and Racial Differences in Stroke (REGARDS) study. The ECL score’s components were: a previously reported evolutionary-concordance diet score, alcohol intake, physical activity, sedentary behavior, waist circumference, smoking history, and social network size. Diet was assessed using a Block 98 food frequency questionnaire and anthropometrics by trained personnel; other information was self-reported. Higher scores indicated higher evolutionary concordance. We used multivariable Cox proportional hazards regression models to estimate ECL score-mortality associations.

Results:

Over a median follow-up of 10.3 years, 3771 deaths occurred (1177 from cardiovascular disease [CVD], 1002 from cancer). The multivariable-adjusted hazard ratios (HR) (95% confidence intervals [CI]) for those in the highest relative to the lowest ECL score quintiles for all-cause, all-CVD, and all-cancer mortality were, respectively, 0.45 (0.40, 0.50), 0.47 (0.39, 0.58), and 0.42 (0.34, 0.52) (all P trend < 0.01). Removing smoking and diet from the ECL score attenuated the estimated ECL score-all-cause mortality association the most, yielding fifth quintile HRs (95% CIs) of 0.56 (0.50, 0.62) and 0.50 (0.46, 0.55), respectively.

Conclusions:

Our findings suggest that a more evolutionary-concordant lifestyle may be inversely associated with all-cause, all-CVD, and all-cancer mortality. Smoking and diet appeared to have the greatest impact on the ECL-mortality associations.

High Glycemic Index Diet Linked to Cardiovascular Disease and Premature Death

Low glycemic index meal

Haven’t we know this for years? From a recent New England Journal of Medicine:

Most data regarding the association between the glycemic index and cardiovascular disease come from high-income Western populations, with little information from non-Western countries with low or middle incomes. To fill this gap, data are needed from a large, geographically diverse population.

METHODS

This analysis includes 137,851 participants between the ages of 35 and 70 years living on five continents, with a median follow-up of 9.5 years. We used country-specific food-frequency questionnaires to determine dietary intake and estimated the glycemic index and glycemic load on the basis of the consumption of seven categories of carbohydrate foods. We calculated hazard ratios using multivariable Cox frailty models. The primary outcome was a composite of a major cardiovascular event (cardiovascular death, nonfatal myocardial infarction, stroke, and heart failure) or death from any cause.

RESULTS

In the study population, 8780 deaths and 8252 major cardiovascular events occurred during the follow-up period. After performing extensive adjustments comparing the lowest and highest glycemic-index quintiles, we found that a diet with a high glycemic index was associated with an increased risk of a major cardiovascular event or death, both among participants with preexisting cardiovascular disease (hazard ratio, 1.51; 95% confidence interval [CI], 1.25 to 1.82) and among those without such disease (hazard ratio, 1.21; 95% CI, 1.11 to 1.34). Among the components of the primary outcome, a high glycemic index was also associated with an increased risk of death from cardiovascular causes. The results with respect to glycemic load were similar to the findings regarding the glycemic index among the participants with cardiovascular disease at baseline, but the association was not significant among those without preexisting cardiovascular disease.

CONCLUSIONS

In this study, a diet with a high glycemic index was associated with an increased risk of cardiovascular disease and death.

How to Prevent Age-Related Muscle Loss

paleo diet, low-carb, Steve Parker MD
This hunter-gatherer snagged himself a brown trout

Axel Sigurdsson, MD, PhD, published a great article on prevention of age-related sarcopenia (loss of muscle mass). Click through for details. To stay vigorous as you age, you should preserve muscle mass and the strength it provides. If you’ve lost muscle mass, you can re-build it. Summary from the good doctor:

Age-related loss of muscle mass (sarcopenia)may start as early as in our thirties and appears to continue for the rest of our lives.

There is also a loss of muscle strength and muscle function. The consequences may often be severe, particularly in the elderly.

Increased physical activity and adequate nutrition are the most powerful tools at our disposal to delay age-related loss of muscle mass.

Well-rounded exercise programs consisting of aerobic and resistance exercises are believed to be most effective

Modification of dietary habits may be an important tool to prevent the decline in muscle mass and function that occurs with aging.

Adequate protein intake is of key importance. Animal-derived protein may provide a higher and broader biological value than vegetable protein.

Fish consumption is recommended and fruits and vegetables should be consumed regularly.

Nutritional supplements containing essential amino acids may be helpful. This is particularly true for whey protein.

Fish-derived protein hydrolysates also appear promising.

Adequate intake of vitamin D is essential.

“Fish-derived protein hydrolysates” doesn’t sound very appetizing. I’ll stick with real fish for now, especially cold-water fatty fish.

For Type 2 Diabetes, Gastric Bypass May Improve Cardiac and Renal Outcomes

Steve Parker MD, bariatric surgery, gastric bypass

Band Gastric Bypass Surgery

From a recent Diabetes Care article:

Our data suggest robust benefits for renal outcomes, heart failure, and CV [cardiovascular] mortality after GBP [gastric bypass] in individuals with obesity and T2DM. These results suggest that marked weight loss yields important benefits, particularly on the cardiorenal axis (including slowing progression to end-stage renal disease), whatever the baseline renal function status.

Because of the risk of surgery, I’d make sure first that diet modification was seriously tried and failed.

Medical Errors May Be the Third Most Common Cause of Death in the U.S.

Hospitals are notorious for iatrogenic deaths

“May be.” But they’re not. The 3rd leading cause of death is accidents (unintentional injuries).

From Dr Gorski at Science Based Medicine (and he’s right):

I say this at the beginning of nearly every post that I write on this topic, but it bears repeating. It is an unquestioned belief among believers in alternative medicine and even just among many people who do not trust conventional medicine that conventional medicine kills. Not only does exaggerating the number of people who die due to medical complications or errors fit in with the world view of people like Gary Null and Joe Mercola, but it’s good for business. After all, if conventional medicine is as dangerous as claimed, then the quackery peddled by the likes of Adams and Mercola starts looking better in comparison. Unfortunately, there are a number of academics more than willing to provide quacks with inflated estimates of deaths due to medical error. The most famous of these is Dr. Martin Makary of Johns Hopkins University, who published a review (not an original study, as those citing his estimates like to claim) estimating that the number of preventable deaths due to medical error is between 250,000 and 400,000 a year, thus cementing the common (and false) trope that “medical error is the third leading cause of death in the US” into the public consciousness and thereby doing untold damage to public confidence in medicine. As I pointed out at the time, if this estimate were correct, it would mean that between 35% and 56% of all in-hospital deaths are due to medical error and that medical error causes between 10% and 15% of all deaths in the US. The innumeracy that is required to believe such estimates beggars the imagination.

Tea May Postpone Death and Prevent Heart Disease

One of my favorite green teas

For years we’ve been hearing about the potential longevity and cardiovascular benefits of green tea. If memory serves, most of the data comes from Japanese studies. Now a Chinese observational study finds 15–20% reductions in atherosclerotic cardiovascular disease (ASCVD) and death, compared to non-tea drinkers. Most of the participants drank green tea, and they did so at least thrice weekly.

From the European Journal of Preventive Cardiology:

Using large prospective cohorts among general Chinese adults, we have provided novel evidence on the protective role of tea consumption on ASCVD events and all-cause mortality, especially among those who kept the habit all along. The current study indicates that tea might be a healthy beverage for primary prevention against ASCVD and premature death.

The researchers point out that results may not apply to non-Chinese populations.

Suicide Rate Among Young Americans Is Skyrocketing

This too shall pass

From The New York Times:

After declining for nearly two decades, the suicide rate among Americans ages 10 to 24 jumped 56 percent between 2007 and 2017, according to data from the Centers for Disease Control and Prevention. And for the first time the gender gap in suicide has narrowed: Though the numbers of suicides are greater in males, the rates of suicide for female youths increased by 12.7 percent each year, compared with 7.1 percent for male youths.
