Shares of Madrigal Pharmaceuticals (MDGL) are soaring after the company announced positive top-line, 36-week results from a Phase 2 clinical trial in patients with biopsy-proven non-alcoholic steatohepatitis. In the trial, MGL-3196 demonstrated statistical significance in the primary endpoint, relative reduction of liver fat on magnetic resonance imaging-estimated proton density fat fraction at 12 weeks and statistically significant results in multiple week 36 endpoints. Shares of Madrigal are up 67%, or $66.57, to $175.00 in premarket trading. Viking Therapeutics (VKTX), which has a thyroid beta agonist in Phase 2 development for the treatment of non-alcoholic fatty liver disease and hypercholesterolemia, is trading up 38% to $6.86. Intercept Pharmaceuticals (ICPT), which has a competing, and further along than Madrigal’s, drug to treat non-alcoholic steatohepatitis is trading down 6% to $69.01.

Divorce is bad for your health
We already know divorce can be bad for your check book and your emotional health. It turns out, it can be bad for your physical health, too.
A new study published in the Annals of Behavioral Medicine, an academic journal, suggests people who divorce have a greater likelihood of smoking and lower amounts of physical activity.
Researchers at the University of Arizona studied more than 5,700 people, using the English Longitudinal Study of Aging, a long-term health study of adults over 50 in the U.K. There are seven sets of data in the study, collected every two years, beginning in 2002. Some 900 of the study participants were divorced or separated and had not remarried. The rest were married.
They reported their life satisfaction, their exercise frequency, smoking status and measurements of their lung function and levels of inflammation. Those who were divorced or separated had a 46% greater risk of dying during the study than their counterparts who were still married. (The researchers controlled for factors like gender, health, age and socioeconomic status.)
Why the deterioration in divorcees’ health? Divorced or separated participants, especially women, were less satisfied with life than their married counterparts in the study, the researchers found. That creates an unhealthy and potentially fatal spiral: Lower satisfaction with life was also linked to lower levels of physical activity and lower levels of physical activity is linked to greater risk for an early death.
That said, not all marriages are the same, and it’s important to distinguish between healthy, happy ones and toxic ones, that might be impacting one or both partners’ health negatively, said Jennifer Behnke, a licensed marriage and family therapist based in Juno Beach, Fla. “In a miserable relationship, you’re sitting on the couch, watching TV, feeling that toxicity of resentment and not getting your needs met,” she said.
But this isn’t the first study that has shown a link between divorce and a negative impact on health. A 2009 study from researchers at the University of Chicago and Johns Hopkins University found that divorced or widowed people have 20% more chronic health conditions, such as heart disease, diabetes or cancer, than married people.
Divorced or widowed people also have 23% more mobility limitations than married people, such as trouble climbing stairs or walking one block. People who never married have about the same number of chronic health conditions as married people. But they do report 13% more depressive symptoms and 12% more mobility limitations than people who are married.
Healthier partners might actually help their spouse stay healthier, too, Bourassa said. “If you imagine a husband or wife who doesn’t smoke and their partner does, one might try to influence the other’s behavior. In many ways, when relationships end, we lose that important social control of our health behaviors.”
Still, divorce doesn’t have to lead to poor health outcomes, the researchers of the latest study said. Quality of life can actually improve for people who have ended relationships that are unhealthy for them. In fact, right after a divorce, individuals will often hit the gym even more, as they re-enter the dating world, Behnke said.
“It’s called a ‘revenge body’ for a reason.”
But smoking and exercise could be important factors to watch in divorcees, Bourassa said. “If we know someone who is divorced, maybe we should ask, ‘Are you smoking? Are you getting enough physical activity?’” he said.
New guideline for HER2 testing in breast cancer
Published today, a Focused Update to the American Society of Clinical Oncology (ASCO)/College of American Pathologists (CAP) guideline for human epidermal growth factor receptor 2 (HER2) testing in breast cancer brings new levels of clarity that will benefit patients and clinical teams alike.
An ASCO-CAP expert panel of pathologists and oncologists developed this Focused Update to address new information made available since the guideline’s previous update in 2013. Notably, the 2018 Focused Update addresses uncommon clinical scenarios and improves clarity, particularly for infrequent HER2 test results that are of uncertain biologic or clinical significance.
For patients with invasive breast cancer, accurate determination of HER2 status of the tumor is essential to ensure that those most likely to benefit are offered a HER2-targeted therapy. At the same time, those who are unlikely to benefit can avoid side effects and costs associated with those drugs.
As primary predictors of how a patient with breast cancer may respond to HER2-targeted therapy, pathologists use in situ hybridization (ISH) tests to assess HER2 gene amplification and can assess protein overexpression by immunohistochemistry (IHC) tests.
“Now, a growing body of clinical outcomes literature and survey data enables us to recommend how to best evaluate some of the less common patterns in HER2 results emerging from ISH,” said Expert Panel co-chair for CAP, Elizabeth Hammond, MD, FCAP, an emeritus professor of pathology at the University of Utah School of Medicine and consultant pathologist at Intermountain Healthcare.
According to ASCO Expert Panel co-chair Antonio Wolff, MD, FACP, FASCO, a professor of oncology at Johns Hopkins, “It is well documented that greater communication among providers-;oncologists and pathologists-;leads to improved results. This update demonstrates that both the CAP and ASCO are committed to collaboration that not only guides best medical practices, but that also serves as a model for other specialties.”
Updated findings of note include:
- Revision of the definition of IHC 2+ (equivocal) to the original FDA-approved criteria.
- Repeat HER2 testing on a surgical specimen if the initially tested core biopsy is negative is no longer stated as mandatory. A new HER2 test may (no longer should) be ordered on the excision specimen on the basis of some criteria (such as tumor grade 3).
- A more rigorous interpretation criteria of the less common patterns that can be seen in about 5% of all cases when HER2 status in breast cancer is evaluated using a dual-probe ISH testing. These cases, described as ISH groups 2 to 4, should now be assessed using a diagnostic approach that includes a concomitant review of the IHC test, which will help the pathologist make a final determination of the tumor specimen as HER2 positive or negative.
- The Expert Panel also preferentially recommends the use of dual-probe instead of single-probe ISH assays, but it recognizes that several single-probe ISH assays have regulatory approval in many parts of the world.
The guideline Focused Update is available online at the ARCHIVES OF PATHOLOGY & LABORATORY MEDICINE. Additionally, the CAP and ASCO developed RESOURCES TO HELP PATHOLOGISTS AND ONCOLOGISTS review and implement the guideline, including a summary of recommendations, a teaching presentation, and testing algorithms.
New Reference Ranges: How Many Kids Really Have High Blood Pressure?
New pediatric blood pressure (BP) clinical practice guidelines were released in 2017 by the American Academy of Pediatrics (AAP).[1] The new guidelines aimed to establish better reference BP ranges for normal-weight children and adolescents by excluding children who were overweight or obese. The new guidelines also changed some of the terminology and definitions of “normal” and “elevated” BP used in the earlier guidelines (Table). The term “prehypertension” is no longer used.
Table. American Academy of Pediatrics Blood Pressure Definitions
| AGE 1-13 YEARS | AGE ≥13 YEARS | |
|---|---|---|
| Normal blood pressure | Systolic and diastolic < 90th percentile | < 120/< 80 mm Hg |
| Elevated blood pressure | ≥ 90th to < 95th percentile or 120/80 mm Hg to < 95th percentile | 120/< 80 mm Hg to 129/< 80 mm Hg |
| Stage 1 hypertension | ≥ 95th percentile to < 95th percentile + 12 mm Hg or 130/80 mm Hg to 139/89 mm Hg(whichever is lower) | 130/80 mm Hg to 139/89 mm Hg |
| Stage 2 hypertension | ≥ 95 percentile + 12 mm Hg or ≥ 140/90 mm Hg (whichever is lower) | ≥ 140/90 mm Hg |
How Many Kids Are Reclassified?
Using data from the National Health and Nutrition Examination Survey (NHANES) collected from 1999 through 2014, a recent study[2] aimed to find out how these new reference values might change the proportion of children diagnosed with hypertension. The data included more than 15,000 children (with representative sampling of minority populations) with a median age of 13.4 years. Using NHANES criteria, 35.9% of the sample children were overweight, with 10.3% defined as obese.
Using the updated AAP definitions, 5.8% of the cohort would have been classified “upward,” in terms of BP classification. About one third of those children were reclassified from “normal” BP to either elevated BP or stage 1 hypertension. Approximately one half of that group had “prehypertension” under the old designation but were now classified as having stage 1 hypertension. Only about 5% of those classified upward moved from stage 1 to stage 2 hypertension.
The reclassified children were more likely to have elevated body mass index, lipid abnormalities, or abnormal A1c levels, representing a high-risk population who may require more thorough evaluation for cardiovascular risk.
The population estimate of elevated blood pressure or hypertension increased from 11.8% to 14.2% with the new blood pressure reference values.
Viewpoint
The fact that 14% of the US child and adolescent population would be classified as having elevated BP or hypertension is an amazing statistic and should cause us to all consider how accurately we measure, assess, and treat abnormal BP in children. There are a couple of cautionary notes. First, the NHANES data collected only a single BP measurement, although presumably it was done in a proper manner. The guidelines suggest measuring BP two or three times in the clinic, especially after having the child sit quietly for 5 minutes. Subsequent BPs after the initial measurement in a clinical setting are often lower, and the average BP should be used.
Even if the 14% figure is an overestimate because the children were classified on the basis of a single BP measurement, the true proportion of children with elevated BPs could still be somewhere around 10%—a high figure.
A full review of the guidelines is beyond the scope of this report, but practitioners should avail themselves of the recommended sequence for lifestyle modification, follow-up intervals, indications for beginning medication, and when to initiate more intense management of hypertension.[1]
Anticholinergics and Dementia: It’s the Drugs
Hello. I’m Dr Charles Vega, and I am a clinical professor of family medicine at the University of California at Irvine. Welcome to Medscape Morning Report, our 1-minute news story for primary care.
It is well known that anticholinergic medications affect cognition, with long-term exposure linked to dementia. Guidelines indicate that they are to be avoided in frail, elderly patients. However, it has been unclear whether the increased risk is specific to the anticholinergic or to the underlying conditions being treated.
A case-control study involving over 300,000 patients suggests that it is the drugs. Antidepressants, drugs for Parkinson’s, and urologic meds increase the risk of developing dementia for up to 20 years after exposure.
The data are observational and the associations were moderate, with an odds ratio ranging from 1.1 to 1.6 for exposure to drugs with a known risk for short-term cognitive dysfunction. However, given the high incidence of dementia, the investigators contend that this represents an appreciable risk to patients.
This study reinforces the need for a thorough drug history in our older patients because drugs with anticholinergic properties are out there in many forms.
States Continue Push to Restrict Abortion
Arkansas’ law adding more regulations on providers of medication abortions is but one example of the increased restrictions that states are seeking to put on abortion providers, according to advocates on both sides of the abortion debate.
The law, which was passed in 2015, requires clinics that provide medication abortions to have a contract with a provider that has admitting privileges at a local hospital. The law was challenged by abortion rights advocates and wound its way through the legal system, eventually making its way to the Supreme Court, which on Tuesday declined to hear the case.
As a result, the ruling of the 8th Circuit U.S. Court of Appeals in favor of the law still stands, although Planned Parenthood has said it will seek a temporary injunction to block the law from taking effect. In the meantime, however, Planned Parenthood has said it will stop providing medication abortions in the state.
The practical effect is that women in Arkansas who are seeking an abortion will now only have one place to go, said Elizabeth Nash, senior state issues associate at the Guttmacher Institute, a pro-abortion rights organization. “There were [originally] three clinics … and two of those clinics only provided medication abortions,” she said in a phone interview. “Those two clinics are closed, and the remaining clinic can only provide — for now — surgical abortions.”
Numbers Down
Arkansas now joins a handful of states that have only one abortion clinic; the others include North Dakota, South Dakota, Wyoming, Mississippi, Kentucky, and West Virginia, Nash said. “In some states, that has curtailed access dramatically,” Nash said. “Women may end up going to other states to access abortion there … or they may be delayed because they found out that they wanted an abortion early in the pregnancy, but they have to arrange an appointment several weeks in advance [since] there is only one clinic to go to.”
Kelly Marcum, legislative assistant at the Family Research Council, a pro-life organization, said in a phone interview that “numerous pro-life bills are moving at the state level.” For example, this past week, Louisiana legislators passed a bill to effectively defund Planned Parenthood in their state; while not mentioning the organization by name, the bill says that abortion providers in Louisiana will not be able to receive Medicaid funds.
And legislation at the federal level — even if it’s not successful — helps move things along in the states, she continued. “Even if a bill at the federal level doesn’t pass,” such as a ban on abortions after 20 weeks that was passed in the House but not the Senate — “we see momentum in the states to get [similar bills] across the finish line. With an administration that’s friendly to the pro-life moment, there is more momentum at the state level” to get these bills through.
In addition, Marcum said, “[President Trump] is putting in strict constitutionalist judges in various circuits, and that will help when these bills get bottled up in the courts.”
New Kind of Restriction
Currently, 43 states have laws that restrict abortion after a certain period of gestation, according to a report by the Guttmacher Institute. In addition, 19 states require an abortion to be performed in a hospital after a specified point in the pregnancy.
The Arkansas law is a relatively new kind when it comes to medication abortions, according to Shivana Jorawar, state legislative counsel, at the Center for Reproductive Rights, a pro-abortion rights group. “We are seeing restrictions on medical abortion and telemedicine, but the requirement of admitting privileges being needed is a little unique,” Jorawar said during a phone interview at which a public relations person was present.
On the other hand, “I do think we’re going to continue seeing more pre-viability abortion bans,” she said. “We’ve been seeing 15-week bans in Louisiana and Mississippi. Those are new in that we haven’t seen 15-week [limits] before, but we have seen gestational bans for as early as 6 weeks, and I do think that more states are going to introduce these blatantly unconstitutional bans,” despite the cost to taxpayers of having to defend them.
In the end, however, the courts will end up protecting a woman’s right to choose, she predicted. “At the end of the day, if this makes it to the Supreme Court, every justice is obligated to respect and follow precedent, and there is a very firm precedent when it comes to abortion,” Jorawar said.
“Less than 2 years ago, [the Supreme Court] reaffirmed [abortion rights] in the Whole Women’s Health case. They made it clear that states can’t have laws that … impose burdens on this very fundamental right with no corresponding benefit, and the existing restrictions we see here fail that test.”
With the closing of Planned Parenthood clinics in states like Arkansas, more crisis pregnancy centers likely will appear, said Marcum. “We’ve seen in numerous states where abortion clinics have closed down that crisis pregnancy centers have grown nearby in response to the fact that there are still women who need help, and they are seeking organizations that will actually help them. What we’d like to see is Title X and Medicaid funds diverted from Planned Parenthood go to crisis pregnancy centers and community health centers that are equipped to empower women.”
Trump Effect
Steven Aden, chief legal officer and general counsel at Americans United for Life, a pro-life organization, agreed that for now, many of these state laws regulating abortion will continue to have a tough time in the courts, including a recently enacted bill in Iowa that would outlaw abortion after a fetal heartbeat is detected, which is usually at around 6 weeks. “We don’t anticipate early-term abortion limits … will make much headway in federal courts at this time,” he said in a phone interview. “We do think [the Iowa law] has an uphill battle.”
However, things could start to change as the Trump administration continues to appoint conservative judges, he added. “At this rate, you’d have to think that the drive to appoint constitutional conservatives/originalist judges will have an impact at some point down the road … just as [more liberal] judges appointed by [President] Obama had an impact.”
For now, there seems to be continued interest among states “to regulate abortion like any other outpatient procedure,” Aden said. “You’ll see principally bills going to surgical center regulation, chemical abortion regulations, and perhaps non-discrimination provisions outlawing abortion based on the baby’s gender or prenatal genetic characteristics.”
There is definitely a need for these types of bills, Aden continued. “In some states it has been shown that up to 90% of babies with Down syndrome are aborted,” he said. “There is certainly genetic counseling and genetic discrimination based on disabilities in the womb.”
“And with respect to gender science, it’s pretty well established that at least internationally and in many metropolitan areas in the U.S. where there’s a high number of immigrants, that there’s a market for abortion based on the gender of the baby, principally because the baby is a girl, so I think that’s important protective legislation,” he added.
