If You Have T2 Diabetes, Odds Are Good That You Already Have Fatty Liver (NAFL)

Stages of liver damage: healthy, fatty, liver fibrosis, and cirrhosis. 

I’ve written before about fatty liver here, here, and here, for example. Fatty liver by itself may not be very harmful but sometimes it progresses to liver inflammation called steatohepatitis. Which can lead to cirrhosis. Non-alcoholic fatty liver disease is the second leading cause for liver transplantation in the U.S., after viral hepatitis.

You only have one liver, so be nice to it.

How common is fatty liver in the U.S. among those with T2 diabetes? From Diabetes Care:

The overall prevalence of NAFLD [non-alcoholic fatty liver disease] was >70% (47% with NAFL [non-alcoholic fatty liver] plus 26% with NASH [non-alcoholic steatohepatitis], for a total of >18 million patients with T2D having NAFLD (not including patients in the U.S. with undiagnosed T2D).

Are Your Drugs So Expensive Due to PBMs?

Compared to Europe and Canada, drugs are about 10 times more expensive in the U.S.

The American Prospect has an eye-opening article from 2017 that sheds light on pharmacy benefits managers (PBMs). Ever heard of them?

Author David Dayen starts with comments from pharmacy owner Frankil talking about how he determines how much money he makes on retail sale of a drug:

Like any retail outlet, Frankil purchases inventory from a wholesale distributor and sells it to customers at a small markup. But unlike butchers or hardware store owners, pharmacists have no idea how much money they’ll make on a sale until the moment they sell it. That’s because the customer’s co-pay doesn’t cover the cost of the drug. Instead, a byzantine reimbursement process determines Frankil’s fee.

“I get a prescription, type in the data, click send, and I’m told I’m getting a dollar or two,” Frankil says. The system resembles the pull of a slot machine: Sometimes you win and sometimes you lose. “Pharmacies sell prescriptions at significant losses,” he adds. “So what do I do? Fill the prescription and lose money, or don’t fill it and lose customers? These decisions happen every single day.”

Frankil’s troubles cannot be traced back to insurers or drug companies, the usual suspects that most people deem responsible for raising costs in the health-care system. He blames a collection of powerful corporations known as pharmacy benefit managers, or PBMs. If you have drug coverage as part of your health plan, you are likely to carry a card with the name of a PBM on it. These middlemen manage prescription drug benefits for health plans, contracting with drug manufacturers and pharmacies in a multi-sided market. Over the past 30 years, PBMs have evolved from paper-pushers to significant controllers of the drug pricing system, a black box understood by almost no one. Lack of transparency, unjustifiable fees, and massive market consolidations have made PBMs among the most profitable corporations you’ve never heard about.

***

In the case of PBMs, their desire for larger patient networks created incentives for their own consolidation, promoting their market dominance as a means to attract customers. Today’s “big three” PBMs—Express Scripts, CVS Caremark, and OptumRx, a division of large insurer UnitedHealth Group—control between 75 percent and 80 percent of the market, which translates into 180 million prescription drug customers. All three companies are listed in the top 22 of the Fortune 500, and as of 2013, a JPMorgan analyst estimated total PBM revenues at more than $250 billion.

***

PMBs initially came about as a means of saving costs. Why hasn’t that panned out?

The biggest reason experts cite is an information advantage in the complex pharmaceutical supply chain.

***

This lack of transparency enables PBMs to enjoy multiple hidden revenue streams from every other player. “It’s OK to have intermediaries, we have Visa,” says David Balto, an antitrust litigator and former top official with the Federal Trade Commission. “But these companies make a fabulous amount of money, even though they’re not buying the drug, not producing the drug, not putting themselves at risk.”

The PBM industry is rife with conflicts of interest and kickbacks. For example, PBMs secure rebates from drug companies as a condition of putting their products on the formulary, the list of reimbursable drugs for their network. However, they are under no obligation to disclose those rebates to health plans, or pass them along. Sometimes PBMs call them something other than rebates, using semantics to hold onto the cash. Health plans have no way to obtain drug-by-drug cost information to know if they’re getting the full discount.

***

It’s a long article and I confess I haven’t read the whole thing yet. I’ve read enough to rile up my sense of indignation! Pharmaceutical companies and health insurers don’t seem too upset. Because costs associated with these third-party shenanigans is simply passed on to the consumer—that’s you—in higher insurance premiums, deductibles, and co-pays.

Alcohol Is Killing Too Many of Us

Irish Whiskey.

According to the National Institute of Alcohol Abuse and Alcoholism, a recent scientific paper found an alarming increase in deaths related to alcohol:

The researchers found that, in 2017, nearly half of alcohol-related deaths resulted from liver disease (31%; 22,245) or overdoses on alcohol alone or with other drugs (18%; 12,954). People aged 45-74 had the highest rates of deaths related to alcohol, but the biggest increases over time were among people age 25-34. High rates among middle-aged adults are consistent with recent reports of increases in “deaths of despair,” generally defined as deaths related to overdoses, alcohol-associated liver cirrhosis, and suicides, primarily among non-Hispanic whites. However, the authors report that, by the end of the study period, alcohol-related deaths were increasing among people in almost all age and racial and ethnic group.

As with increases in alcohol consumption and related medical emergencies, rates of death involving alcohol increased more for women (85%) than men (35%) over the study period, further narrowing once large differences in alcohol use and harms between males and females. The findings come at a time of growing evidence that even one drink per day of alcohol can contribute to an increase in the risk of breast cancer for women. Women also appear to be at a greater risk than men for alcohol-related cardiovascular diseases, liver disease, alcohol use disorder, and other consequences.

“Alcohol is a growing women’s health issue,” said Dr. Koob. “The rapid increase in deaths involving alcohol among women is troubling and parallels the increases in alcohol consumption among women over the past few decades.”

Metformin: New Uses for an Old Drug

Metformin? A shirt from 1967?

Medical Xpress has an article about the possible future uses of metformin for weight loss, prostate cancer treatment, and tuberculosis treatment. It didn’t mention metformin as an anti-aging drug.

From the article:

Among medications, metformin has a long and storied past. The compound destined to become metformin was first isolated during the Middle Ages from the French lilac, a plant scientifically known as Galega officinalis. Ground flowers and leaves were administered by healers to patients suffering from constant urination, a hallmark of a disorder that later would become known as diabetes. The active ingredient in French lilac, a plant also called goat’s rue, was identified hundreds of years later as galegine, which triggered a striking reduction in blood glucose.

By the 1950s, scientists were able to exploit folk medicine uses and develop the drug that became metformin.

Source: Wonder drug? Exploring the molecular mechanisms of metformin, a diabetes drug with Medieval roots

Don’t believe everything you read. The article claims metformin’s effectiveness in type 2 diabetes is primarily due to weight loss. Conventional thinking is that it’s mostly due to decreased production and release of glucose by the liver. I guess time will tell which theory wins out. In either case, it’s a good initial drug for T2 diabetes if diet and exercise prove inadequate.

Prepare Your Household for Coronavirus

Advanced civilizational collapse

I hadn’t been too concerned about coronavirus (COVID-19), but then I read about quarantined towns in northern Italy. I’m still not terribly worried for my own health, even if I end up treating cases at the hospital. I’m 65—a risk factor for viral death—but otherwise healthy, thank God! There’s still a good chance this will blow over and not affect the U.S. in a major way.

BUT…

If coronavirus becomes an epidemic in the U.S., you will want to be prepared. You’ll want to avoid unnecessary contact with others, especially if you’re over 65 or have significant chronic medical conditions like heart disease, COPD, asthma, active cancer, impaired liver or kidney function, or a poor immune system (e.g, cancer chemotherapy).

If your city or neighborhood is quarantined, will supply trucks be allowed through the checkpoints? Will drivers be willing to enter the quarantine zone? I’ve started to call Wal-Mart, “China-Mart.” Because is it seems like at least half the goods there are made in China. China’s industrial output has already been reduced by the coronavirus epidemic there. A significant number of prescription drugs in the U.S. depend on a healthy China.

A severe coronavirus outbreak in the U.S. might mean you need to hunker down at home, or close to it, for one or two months. So consider stocking up on the following items to last for 4–6 weeks. The good new is, you’ll eventually use most of this anyway.

  • various foods with a long shelf-life
  • face masks (you’re too late; this ship has already sailed)
  • toilet paper
  • paper towels
  • over-the-counter cold and flu remedies
  • acetaminophen
  • ibuprofen
  • throat lozenges
  • antiseptic wipes
  • toothpaste
  • a multivitamin
  • hand sanitizer
  • facial tissues
  • important prescription medicines (you may need to call your doctor for a three-month supply)
  • body soap
  • dishwashing and clothing detergents
  • feminine hygeine products
  • household cleaning products

Have I missed anything?

Fasting: Not Ready for Prime Time?

This caveman probably went days without food, and often

Dr Axel Sigurdsson published an epic post on intermittent fasting early in 2020. I don’t doubt anything in it although I haven’t yet taken a deep dive into the subject like he has. I touched on it here, here, here, and here. I’ve done some 24-hour fasting myself (here and here).

From the good doctor:

Animal studies suggest that intermittent fasting may have several health benefits. Some of these benefits, in particular, the effects on obesity, type 2 diabetes, and cardiovascular risk factors, have been confirmed in studies on humans.

However, the popularity of intermittent fasting within the general public is in stark contrast with the gaps in evidence on the clinical benefits of this approach.

PS: PWDs taking drugs that can cause hypoglycemia would have to be extremely careful about fasting, working with their doctors or CDEs.

Here’s Why U.S. Healthcare Is So Expensive

U.S. healthcare needs to be resuscitated

The U.S. has a presidential and other federal elections later this year. So we’ll be hearing more talk about healthcare reform. Mostly talk, not much action. Healthcare is an issue because it soaks up 18% of GDP (Gross Domestic Product). Many of us think that’s way too much and we can’t afford it anymore. Most other fully developed Western nations spend 9–11% of GDP on healthcare. Are we in the U.S. getting our money’s worth? Probably not, if you look at things like longevity, infant mortality rates, and overall disease burden.

When I aim to cure a disease, it helps immensely if I know the cause of the disease. That determines the treatment plan. If we want to fix over-spending on healthcare, we need to know the causes. With the right treatment plan, we might get healthcare costs down to 5% of GDP.

On the other hand, perhaps we in the U.S. love spending 18% of GDP on healthcare. It provides a lot of jobs. I personally make a very nice living with it. Nowhere near the $7.7 million/year of the average NBA player or $2.7 million/year for the average NFL player. At least I know I’m saving lives and alleviating suffering.

Here are the causes of overly-expensive healthcare:

  • Lack of price transparency
  • Third-party payer between patient and provider (they must be paid). Third party may not care about cost; just pass it on via premiums, or insulate themselves via high deductibles.
  • Defensive Medicine: excessive testing and consultations, malpractice insurance premiums, time away from patient care
  • Excessive regulation
  • Government essentially mandates Emergency Department care regardless of ability to pay
  • Excessive administrative costs (bureaucracy) of a byzantine system: providers’ office, healthcare insurance, hospital administration, regulators
  • Lobbying protects insurers, doctors, hospitals, Big Pharma at the expense of consumers
  • Low or no deductibles (no skin in the game)
  • Little incentive for patient to get or stay healthy
  • Government and insurers pay lousy docs the same fee as good doctors, so no incentive for great care or innovation. If you want to improve healthcare, you must financially reward competent and successful competitors. 
  • Providers are incentivized to provide services: provide more services, earn more pay
  • Greed
  • Insurance mandates
  • Government price controls (Medicare and Medicaid)
  • Inadequate competition among providers
  • Un-enforced anti-trust and consumer protection laws 
  • Excessive drug costs
  • Over-utilization of specialist care instead of primary care
  • Laws prevent importation of drugs by patients or providers from cheaper markets
  • Insurance companies prohibited from selling across state lines?
  • Pharmacy Benefits Management Co’s
  • Insurance pays for too much, instead of only catastrophic care?
  • Waste and fraud?
  • Monopolies or near-monopolies (e.g., dominant hospital systems, insurance companies)?

PS: Below are some interesting links I found while researching this post.

From Investopedia in 2019:

“Even with all this money being spent on healthcare, the World Health Organization ranked the U.S. 37th in healthcare systems, and The Commonwealth Fund placed the U.S. last among the top 11 industrialized countries in overall healthcare.”

 From CNBC.com March 2018:

“The real difference between the American health care system and systems abroad is pricing.”

From JAMA Network March 2018:

“The United States spent approximately twice as much as other high-income countries on medical care, yet utilization rates in the United States were largely similar to those in other nations. Prices of labor and goods, including pharmaceuticals, and administrative costs appeared to be the major drivers of the difference in overall cost between the United States and other high-income countries.”

Yale Insights 2016 report focusing on hospitals:

“This study tells us that insurance premiums are so high because healthcare provider prices are incredibly high. The way to rein in the cost of healthcare services is by targeting the massive variation in providers’ prices. We can do that by making prices more transparent, making these markets more dynamic, and really blunting the monopoly power that a lot of large healthcare providers have, which has allowed them to raise prices.” Interviewee says the hospital industry is 8% of GDP.

Prevent Dementia With This Healthy Lifestyle

Yes, some cases of dementia are preventable. If you have a genetic predisposition to develop dementia, the deck is stacked against you. But it’s not hopeless. A healthy lifestyle will help you, too.

The research at hand was done in the UK and involved over 500,000 older adults of European ancestry, free of dementia and cognitive impairment at baseline.

So what are the healthy lifestyle characteristics linked to lower risk of dementia, whether you have genetic risk or not?

  • Physical activity
  • Not smoking
  • Healthy diet
  • Judicious alcohol consumption

Lifestyle details from the research report:

A healthy lifestyle score was constructed based on 4 well-established dementia risk factors (smoking status, physical activity, diet, and alcohol consumption) assessed at baseline using a touchscreen questionnaire. Participants scored 1 point for each of 4 healthy behaviors defined on the basis of national recommendations (full details in eTable 1 in Supplement 1). Smoking status was categorized as current or no current smoking. Regular physical activity was defined as meeting the American Heart Association recommendations of at least 150 minutes of moderate activity per week or 75 minutes of vigorous activity per week (or an equivalent combination) or engaging in moderate physical activity at least 5 days a week or vigorous activity once a week. Healthy diet was based on consumption of at least 4 of 7 commonly eaten food groups following recommendations on dietary priorities for cardiometabolic health, which are linked to better late-life cognition and reduced dementia risk. Previous studies of alcohol consumption and dementia risk support a U-shaped relationship, with moderate consumption associated with lower risk. Therefore, moderate consumption was defined as 0 to 14 g/d for women and 0 to 28 g/d for men, with the maximum limit reflecting US dietary guidelines.

Source: Association of Lifestyle and Genetic Risk With Incidence of Dementia | Dementia and Cognitive Impairment | JAMA | JAMA Network

What do they consider a healthy dementia-preventing diet? At least four of the following food groups and consumption levels:

  • Fruits: 3 or more servings a day
  • Veggies: 3 or more servings a day
  • Fish: 2 or more servings a week
  • Processed meats: no more than 1 serving a week
  • Unprocessed red meats: no more than 1.5 servings a week
  • Whole grains: 3 or more servings a day
  • Refined grains: no more than 1.5 servings a day

Regarding alcohol, the guideline is no more than one drink a day for women, and no more than two a day for men. Do a web search for standard drink sizes if needed. “One drink” is 14 grams of pure alcohol.

Alarming Rise In Suicides Among Young Americans

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.

If you or someone you know needs help dealing with suicidal thought, please please please contact the National Suicide Prevention Lifeline at 1-800-273-8255.

High Protein Diet May Prevent Weight Regain

Filet mignon and sautéed asparagus

Weight loss can change your metabolism in such a way that promotes regain of lost weight. For successful weight-losers with prediabetes, a higher protein diet could help with prevention of regain. How much higher protein? 25% versus the usual 15% of calories from fat.

This is important research since most people who lose fat weight gain it back, typically 6–12 months later.

For the boring details, keep reading.

ABSTRACT

Background

Weight loss has been associated with adaptations in energy expenditure. Identifying factors that counteract these adaptations are important for long-term weight loss and weight maintenance.

Objective

The aim of this study was to investigate whether increased protein/carbohydrate ratio would reduce adaptive thermogenesis (AT) and the expected positive energy balance (EB) during weight maintenance after weight loss in participants with prediabetes in the postobese state.

Methods

In 38 participants, the effects of 2 diets differing in protein/carbohydrate ratio on energy expenditure and respiratory quotient (RQ) were assessed during 48-h respiration chamber measurements ∼34 mo after weight loss. Participants consumed a high-protein (HP) diet (n = 20; 13 women/7 men; age: 64.0 ± 6.2 y; BMI: 28.9 ± 4.0 kg/m 2) with 25:45:30% or a moderate-protein (MP) diet (n = 18; 9 women/9 men; age: 65.1 ± 5.8 y; BMI: 29.0 ± 3.8 kg/m 2) with 15:55:30% of energy from protein:carbohydrate:fat. Predicted resting energy expenditure (REEp) was calculated based on fat-free mass and fat mass. AT was assessed by subtracting measured resting energy expenditure (REE) from REEp. The main outcomes included differences in components of energy expenditure, substrate oxidation, and AT between groups.

Results

EB (MP = 0.2 ± 0.9 MJ/d; HP = −0.5 ± 0.9 MJ/d) and RQ (MP = 0.84 ± 0.02; HP = 0.82 ± 0.02) were reduced and REE (MP: 7.3 ± 0.2 MJ/d compared with HP: 7.8 ± 0.2 MJ/d) was increased in the HP group compared with the MP group (P < 0.05). REE was not different from REEp in the HP group, whereas REE was lower than REEp in the MP group (P < 0.05). Furthermore, EB was positively related to AT (rs = 0.74; P < 0.001) and RQ (rs = 0.47; P < 0.01) in the whole group of participants.

Conclusions

In conclusion, an HP diet compared with an MP diet led to a negative EB and counteracted AT ∼34 mo after weight loss, in participants with prediabetes in the postobese state. These results indicate the relevance of compliance to an increased protein/carbohydrate ratio for long-term weight maintenance after weight loss. The trial was registered at clinicaltrials.gov as NCT01777893.
