In 2017, Sanofi Genzyme launched a phase 2 clinical trial of a drug designed to target a specific genetic mutation in some patients with Parkinson’s disease. Researchers hoped the drug would slow or even stop disease progression.

Like many before it, the trial yielded disappointing results and the company shut it down in 2021. It was the latest in a string of unsuccessful clinical trials testing disease-modifying Parkinson’s disease drugs.

Although it failed, the Sanofi Genzyme study was different: It was the first to enroll patients with Parkinson’s disease who had a specific genotype and marked the earliest days of precision medicine and gene-specific drug development for the disease.

Once thought to play only a small role in a small number of patients with Parkinson’s disease, a growing body of work has prompted researchers and drug developers to take a longer look at how genetics influence Parkinson’s disease risk and progression.

“We’re about to enter this era of precision medicine for Parkinson’s disease, which makes genetic testing important,” said James Beck, PhD, senior vice president and chief scientific officer for the Parkinson’s Foundation.

“A number of companies have clinical trials or are in preparation for clinical trials to test some specific therapies that would depend upon people having a specific genetic mutation,” he said.

Today, at least four clinical trials of drugs that target specific Parkinson’s disease-related gene variants on LRRK2 and GBA are under way, and more are in the pipeline. Whether these drugs will be effective at modifying the course of the disease remains to be seen. First, the trials must enroll enough patients. And therein lies the challenge: Genetic testing isn’t part of routine Parkinson’s disease care and isn’t covered by most insurance policies. Most patients don’t know their genotype.

It’s a significant roadblock to the future of a precision medicine approach that is based on a patient’s individual genotype, which some experts argue offers the best shot at slowing disease progression.

“To enroll in clinical trials for precision drugs people with Parkinson’s disease have to be aware of their genetic status,” said Roy N. Alcalay, MD, chief of the movement disorders division at Tel Aviv Medical Center in Israel and part-time associate professor at Columbia University in New York. “How can a person with Parkinson’s and a LRRK2 mutation join a precision medicine trial for LRRK2 if she does not know she is a LRRK2 carrier?”
 

Free genetic testing

Previous studies have shown that some genetic variants increase the risk for Parkinson’s disease after exposure to environmental factors such as pesticides. Research has also shown that a patient’s genotype can predict survival time and that certain medications may prove more effective at slowing disease progression in patients with specific genotypes. All of this points to a significant role for genetics in a disorder that is rapidly increasing.

This makes expanding patient access to genetic testing even more important, Dr. Alcalay said, noting that it’s equally important that patients are informed of their genotype, something that doesn’t usually happen in blinded clinical trials.

To that end, Dr. Alcalay hopes a national genetics study he is leading will address access and need-to-know issues. PD GENEration, a project launched in 2019 by the Parkinson’s Foundation, offers patients free genetic testing for seven clinically relevant Parkinson’s disease-related genes.

Testing is done at home or in a nearby clinic and the results are shared with patients during a free genetic counseling session and with site investigators. Patient samples are stored in a genetic data bank that is open to researchers around the world.

“We surveyed clinical trialists in the Parkinson’s disease field prior to initiation of PD GENEration and estimated that over 90% of people with Parkinson’s disease prior to the effort were not aware of their genetic status,” Dr. Alcalay said.

“I think precision medicine in Parkinson’s disease will not happen without PD GENEration or similar efforts.”
 

‘Overwhelming’ patient interest

Participants in the study are screened for variants in seven genes known to be involved in Parkinson’s disease risk: GBA, LRRK2, PRKN, PINK1, SNCA, PARK7, and VPS35.

In less than 3 years, the study has already produced what is thought to be the largest genetic data bank of sequenced sets of Parkinson’s disease-risk genes made accessible to patients. Since the end of 2020, the first year of patient enrollment, the number of participants has increased from 676 to 10,515 and the number of participating clinical sites rose from 12 to 101.

The foundation has spent nearly $20 million on the project so far and plans to spend another $10 million to reach a goal of 15,000 patients. The study, which is funded by private donors, is so successful that the foundation has had to scale back enrollment.

“When we were at a peak, we had over 700 participants enrolling each month,” Dr. Beck said. Beginning in April, the program capped new sign-ups to 200 patients per month and created a waiting list for future enrollment. The waiting list is hundreds of patients long.

“The participants’ response to enroll in PD GENEration demonstrates there is an overwhelming interest by people with Parkinson’s disease to learn more about their genetic risk factors,” Dr. Alcalay said.
 

A research driver

Nearly 60% of participants enrolled so far are male and close to 80% are White. The average age is 69 years and 44% were diagnosed in the past 5 years. Close to 75% had never participated in a clinical trial.

Nearly 13% have tested positive for mutations on at least one of the seven target genes. Previous studies had suggested genetics were involved in only about 10% of cases.

The majority of those with positive results had early-onset Parkinson’s disease, high-risk ancestry, or a first-degree relative with the disease. However, 9% of people who tested positive weren’t in any of those categories.

Genetic information collected by the project is shared with the Global Parkinson’s Genetics Program (GP2), a resource program of the Aligning Science Across Parkinson’s initiative that is focused on the disease’s genetic architecture. Researchers around the world have access to GP2 data to study known gene variants and identify new ones.

PD GENEration participants can choose to be notified if they are carriers of gene variants discovered in the future.

“All DNA samples shared by participants are undergoing research-grade testing,” Dr. Beck said. “Not only do we want to be able to inform people with Parkinson’s disease about their genetic status, but we also want to be able to use this precious resource to further drive research into the genetics of Parkinson’s disease.”
 

Early success

Patient recruitment has long been one of the biggest challenges to any clinical trial’s success. Research suggests that 90% of all clinical trials fail to reach recruitment milestones in their allotted time frame and two-thirds of multicenter trials fold because too few patients sign up. Data from the Parkinson’s Foundation show that only about 1% of all patients with Parkinson’s disease participate in clinical trials.

Increasing those numbers is the primary goal of PD GENEration, Dr. Beck said. And there’s evidence it’s already paying off.

Earlier this year, one of the program’s participating clinical sites, Intermountain Health, in Salt Lake City, Utah, joined a phase 2 clinical trial of an experimental drug that targets a mutation on the GBA1 gene.

“One of the reasons we were able to participate was when we got the call about joining, we were able to say that we had patients with that specific gene mutation, and we could only say that because the patients had been genotyped through PD GENEration,” said Kathleen E. McKee, MD, director of movement disorders, associate medical director of neurosciences research, and PD GENEration principal investigator at Intermountain Health.

Since 2021, Dr. McKee has enrolled hundreds of patients in the foundation’s gene study and hopes to enroll even more. Few patients turn down the opportunity to participate, she added. Knowing their genotype has proven empowering for her patients, most of whom could not afford genetic testing on their own.

“Previously I would tell patients this is not going to change your immediate management,” Dr. McKee said. “Now I tell my patients that these trials are out there, it may actually change how I treat you and what I recommend.”

Continuous glucose monitors (CGMs) may help curb the severity of hypoglycemia after weight loss operations and even other gastrointestinal procedures, according to recent findings from a small study published in Diabetes, Obesity, and Metabolism.

Hypoglycemia is a chronic and persistent complication common in patients following bariatric surgery, affecting as many as 30% of people who undergo a sleeve gastrectomy or Roux-en-Y gastric bypass.

The symptoms of hypoglycemia, including lightheadedness, heart palpitations, difficulty concentrating, and confusion, can mimic anxiety disorders, arrhythmia, and dumping syndrome.

If a postoperative patient experiences these symptoms within a few hours following a meal or exercising, “primary care doctors should consider the possibility that hypoglycemia may be a contributor,” said Mary-Elizabeth Patti, MD, director of the Hypoglycemia Clinic at the Joslin Diabetes Center in Boston and senior author of the new study. 

“In fact, hypoglycemia is a possible diagnosis even among those who underwent [operations other than bariatric, including] fundoplication or other upper gastrointestinal or esophageal surgeries,” she said. 

To understand how CGM could benefit patients, Dr. Patti and colleagues recruited 22 participants who had undergone bariatric surgery more than 8 years prior and had postbariatric hypoglycemia. Their mean age was 51 years, 90% were women, 82% were diagnosed with level 3 hypoglycemia, and none had type 1 or 2 diabetes. 

All participants experienced neuronal dysfunction with symptoms like fatigue, concentration difficulties, and confusion. More than 90% had received medical nutrition therapy for postbariatric hypoglycemia in the past.

CGM data were collected in the 22 individuals in two sequential phases: masked (no access to sensor glucose or alarms) and unmasked (access to sensor glucose and alarms for low or rapidly declining sensor glucose). Twelve participants wore a CGM (Dexcom G4 device) for a total of 28 days, whereas 10 wore a CGM (the Dexcom G6 device) for a total of 20 days.

The team observed that the percentage of time when the participants’ blood glucose was below 70 mg/dL – the definition of hypoglycemia – was significantly lower during the unmasked phase. 

Though CGM devices are not sensitive enough to serve as a diagnostic tool for hypoglycemia, “the alarms on CGM devices can provide some much-needed awareness,” Dr. Patti said. “After a detailed diagnosis, CGM devices can be a helpful tool to assess dietary patterns and make modifications that could reduce the severity of postbariatric hypoglycemia.”

If a patient frequently experiences hypoglycemia, they may not sense when their glucose levels drop, also known as hypoglycemia unawareness, according to Dr. Patti. Studies have found that postbariatric hypoglycemia remains underdiagnosed because most patients are asymptomatic. 

“The use of CGM devices may improve safety in postbariatric hypoglycemia, particularly for patients with hypoglycemia unawareness,” the researchers conclude.
 

Next steps 

Patients are more vulnerable to hypoglycemia after a sleeve gastrectomy or gastric bypass surgery because these procedures involve removing the pylorus. This valve plays a crucial role in only allowing small portions of food to enter the intestine and prevents sudden spikes in blood glucose.

Without the pylorus, large amounts of food directly enter the intestine and soon result in large amounts of glucose getting absorbed, according to Sriram Machineni, MD, an associate professor of medicine at Albert Einstein College of Medicine, New York, who was not affiliated with the study.

“The pancreas then goes into overdrive and produces a lot of insulin, which continues reducing sugar levels,” Dr. Machineni said. “That is what causes hypoglycemia.”

Dr. Patti and associates are next working on research using CGM-derived data to investigate how different types of meals, physical activities, and other factors could influence glucose metabolism patterns in patients with hypoglycemia.

The study was funded by Dexcom, a manufacturer of continuous glucose monitoring systems. Dr. Patti reported receiving grant funding from the Diabetes Research Center.

“The use of CGM devices may improve safety in postbariatric hypoglycemia, particularly for patients with hypoglycemia unawareness,” the researchers conclude.
 

Next steps 

Patients are more vulnerable to hypoglycemia after a sleeve gastrectomy or gastric bypass surgery because these procedures involve removing the pylorus. This valve plays a crucial role in only allowing small portions of food to enter the intestine and prevents sudden spikes in blood glucose.

Without the pylorus, large amounts of food directly enter the intestine and soon result in large amounts of glucose getting absorbed, according to Sriram Machineni, MD, an associate professor of medicine at Albert Einstein College of Medicine, New York, who was not affiliated with the study.

“The pancreas then goes into overdrive and produces a lot of insulin, which continues reducing sugar levels,” Dr. Machineni said. “That is what causes hypoglycemia.”

Dr. Patti and associates are next working on research using CGM-derived data to investigate how different types of meals, physical activities, and other factors could influence glucose metabolism patterns in patients with hypoglycemia.

The study was funded by Dexcom, a manufacturer of continuous glucose monitoring systems. Dr. Patti reported receiving grant funding from the Diabetes Research Center.

A new discovery of differences between the eyes of people with and without diabetes could point to new approaches for treating diabetic keratopathy, as well as other diabetes-related wound healing problems.

Vision loss caused by diabetes arises primarily from retinopathy, but up to 70% of people with diabetes also experience corneal problems, including keratopathy and neuropathy. Diabetic keratopathy involves impairments in epithelial wound healing, barrier function, and tear production, along with epithelial erosions and keratitis. As a result, the cornea may heal more slowly and less completely following an injury or procedures such as cataract surgery or laser therapy for diabetic retinopathy.

The abnormal wound healing is caused by impaired limbal epithelial stem cells, and the new research, published online in Diabetologia, involved isolation of those cells from 30 donor eyes of humans with and 23 without diabetes. Significant differences were found in DNA methylation between the cells of those two groups. Specifically, the WNT5A gene was hypermethylated at the promotor region in the diabetic cells and its protein markedly repressed.

However, treatment with various approaches, including exogenous WNT5A methylation inhibitors and a nanoconjugate that inhibits WNT5A suppression, improved corneal epithelial wound healing as well as expression of the limbic epithelial stem cells.

“Overall, [the] Wnt-5a [protein] is a new corneal epithelial wound healing stimulator that can be targeted to improve wound healing and stem cells in the diabetic cornea,” wrote Ruchi Shah, PhD, of the Board of Governors Regenerative Medicine Institute, Cedars-Sinai Medical Center, Los Angeles, and colleagues.

The finding represents more cellular changes than researchers had previously been aware of, study senior author Alexander Ljubimov, PhD, DSc, director of the eye program at the Institute, said in a statement.

“The discovery does not affect gene sequence but entails specific DNA modifications altering gene expression – what are known as epigenetic alterations,” he said.

In the experiments, treatment of the impaired diabetic limbal epithelial cells with the exogenous Wnt-5a accelerated wound healing by 1.4-fold (P < .05), compared with untreated cells and reduced healing time in diabetic organ-ultured corneas by 37% (P < .05).

Treatment with the DNA methylation inhibitor zebularine also increased levels of Wnt-5a in the diabetic limbic epithelial cells by 37% (P < .01), dose-dependently stimulated wound healing by 60% at 24 hours (P < .01), and improved wound healing by 30% in diabetic organ-cultured corneas.

The finding of Wnt-5a as a new diabetic corneal marker regulating wound healing and stem cell function may have implications for other diabetes complications involving impaired wound healing, including diabetic foot ulcers, as they share similar neurovascular, sensory, and immunological compromise with diabetic eye disease, Dr. Shah and colleagues wrote.

“Novel therapies to reverse both types of epigenetic silencing could benefit corneal function and may also prove to be beneficial in other wound healing–related diabetic complications,” they wrote.

The investigators are now working on combination therapies that target both mRNA and DNA methylation in hopes of obtaining even better wound healing.

“Our goal is to develop topical, sustained-release drugs for corneal wound healing,” said Dr. Ljubimov. “Drugs that are [Food and Drug Administration] approved and could be easily applied may be one of the most promising approaches for effective future therapies.”

A defined exercise program significantly improved cardiometabolic health and body composition in children with overweight and obesity, but no effect was seen on mental health, based on data from 92 children.

Childhood obesity is associated with negative health outcomes including type 2 diabetes, cardiovascular disease, and mental health disorders, and exercise is considered essential to treatment, wrote Jairo H. Migueles, PhD, of the University of Granada, Spain, and colleagues. However, the effect on children with obesity and overweight of an exercise program on physical and mental health, including within-individual changes, has not been well studied, they said.

In a study published in JAMA Network Open, the researchers reviewed data from 36 girls and 56 boys with overweight or obesity who were randomized to a 20-week exercise program with aerobic and resistance elements, or waitlisted to serve as controls. The participants ranged in age from 8 to 11 years with a mean age of 10 years. The data were collected between Nov. 1, 2014, and June 30, 2016, as part of a parallel-group randomized clinical trial. The exercise program consisted of three to five 90-minute exercise sessions per week for 20 weeks, and the control children continued their usual routines.

The main cardiometabolic outcomes measured in the study were divided into three categories: body composition, physical fitness, and traditional risk factors (waist circumference, blood lipid levels, glucose levels, insulin levels, and blood pressure).

A cardiometabolic risk score was defined by z score. The researchers also added cardiorespiratory fitness (CRF) to the cardiometabolic risk score. Mental health was assessed using composite standardized scores for psychological well-being and poor mental health.

After 20 weeks, cardiometabolic risk scores decreased by approximately 0.38 standard deviations in the exercise group compared with the control group. In addition, specific measures of cardiometabolic health improved significantly from baseline in the exercise group compared with control children for low-density lipoprotein (change of –7.00 mg/dL), body mass index (–5.9 kg/m²), fat mass index (−0.67), and visceral adipose tissue (31.44 g).

Cardiorespiratory fitness improved by 2.75 laps in the exercise group compared with control children. In addition, significantly more children in the exercise group showed meaningful changes (defined as individual changes of at least 0.2 SDs) compared with control children in measures of fat mass index (37 vs. 17, P < .001) and CRF performance (30 vs. 17, P = .03).

However, no significant effects appeared on mental health outcomes in exercisers, the researchers noted.

The reduction in cardiometabolic score was attributable mainly to improvements in cardiovascular fitness, blood lipid levels, and total and visceral adiposity, the researchers wrote in their discussion. The lack of changes in mental health measures may be a result of the healthy mental state of the children at the study outset, they said. “The null effect on mental health outcomes needs to be further investigated, including, among other things, whether the instruments are sensitive enough to detect changes and whether there is a ceiling effect in young children who might be mentally healthy overall,” they wrote.

The findings were limited by several factors, including the relatively small sample size and lack of blinding for some evaluators. However, the results show the potential of exercise programs to affect meaningful change and improve cardiometabolic health in overweight and obese children, although more research is needed to explore the effects of larger-scale and longer-lasting public health interventions combining exercise and other health behaviors such as diet, the researchers concluded.
 

Bottom line: Exercise works

The increasing rates of overweight and obesity in children in the United States have “significant downstream consequences that include increased risk of metabolic disease, including diabetes and hypertension, as well as increased rates of anxiety and depression,” Neil Skolnik, MD, professor of family and community medicine at the Sidney Kimmel Medical College of Thomas Jefferson University, Philadelphia, said in an interview.

Therefore, the effect of interventions such as exercise training on outcomes is important, he said. 

The current study findings are “what you would hope for and expect – improvement in cardiometabolic parameters and fitness,” said Dr. Skolnik. “It was encouraging to see the effect of this relatively short duration of intervention has a clear positive effect on weight, BMI, and cardiometabolic parameters,” he said. “The real benefit, of course, comes from sustaining these habits over a long period of time.”

The lack of improvement in mental health is not surprising given the small study population “who did not have a high rate of mental health problems to begin with,” Dr. Skolnik added.

Barriers to promoting exercise programs for obese and overweight children in primary care are many, Dr. Skolnik said, including “having the motivation and funding to create programs like this so they are readily available to youth.”

However, the key message from the current study is simple and straightforward, according to Dr. Skolnik. “Exercise works! It works to improve fitness, cardiometabolic parameters, and weight control,” he said.

“There is always room for more research,” Dr. Skolnik added. The questions now are not about whether exercise benefits health; they are about figuring out how to implement the known benefits of exercise into daily living for all children, athletes and nonathletes alike, he said. “We need to find nonjudgmental ways to encourage exercise as a part of routine daily healthy living, up there with brushing teeth every day,” he emphasized.

The study was supported by grants from the Spanish Ministry of Economy and Competitiveness and El Fondo Europeo de Desarrollo Regional (FEDER) and by the MCIN (Ministerio de Ciencia e Innovación) / AEI (Agencia Estatal de Investigación. The researchers and Dr. Skolnik had no financial conflicts to disclose. Dr. Skolnik serves on the editorial advisory board of Family Practice News.

This past June, during the search for the Titan submersible, and since then, we’ve had a not-entirely-unexpected development: Sick humor.

There was a lot of it. The Subway owner who got reprimanded for putting “Our subs don’t implode” on his sign was minor league compared with other things circulating on the Internet. One example that was sent to me showed the late Stockton Rush, OceanGate’s co-owner, as the new spokesman for Cap’n Crunch.

Of course, this is nothing new. People have made jokes about awful situations since to the dawn of civilization.

Why do we do this?

Humor is a remarkably human trait. There’s evidence other mammals have it, but not to the extent we do. We’ve created a multitude of forms that vary between cultures. But there isn’t a civilization or culture on Earth that doesn’t have humor.

Why we developed it I’ll leave to others, though I assume a key part is that it strengthens bonds between people, helping them stick together in the groups that keep society moving forward.

Sick humor is part of this, though having grown up watching Monty Python and reading National Lampoon magazine I’m certainly guilty of enjoying it. To this day I think “Eating Raoul” is one of the greatest comedies ever.

It’s also pretty common in medicine. I’ve been involved in plenty of hospital situations that were quite unfunny, yet there are always jokes about it flying as we work.

I assume it’s a defense mechanism. Helping us cope with a bad situation as we do our best to deal with it. Using humor to put a block between the obvious realization that someday this could happen to us. To help psychologically shield us from something tragic.

Years ago I was trying to describe the plot of “Eating Raoul” and said “if you read about this sort of crime spree in a newspaper you’d be horrified. But the way it’s handled in the movie it’s hysterical.” Perhaps that’s as close to understanding sick humor as I’ll ever get. It makes the unfunny funny.

Perhaps the better phrase is the more generic “it’s human nature.” We seek relief in humor, even (maybe especially) in bad situations of our own and others.

Whether or not it’s funny depends on the person. There were plenty of people horrified by the Subway sign, enough that the owner had to change it. But there were also those who admitted they found it tasteless, but still got a laugh out of it. I’m sure the families of those lost on the Titan were justifiably upset, but the closer you get to a personal tragedy the more serious it is.

There’s a fine line, as National Lampoon put it, between funny and sick. But it’s also part of who we are.

Of course, this is nothing new. People have made jokes about awful situations since to the dawn of civilization.

Why do we do this?

Humor is a remarkably human trait. There’s evidence other mammals have it, but not to the extent we do. We’ve created a multitude of forms that vary between cultures. But there isn’t a civilization or culture on Earth that doesn’t have humor.

Why we developed it I’ll leave to others, though I assume a key part is that it strengthens bonds between people, helping them stick together in the groups that keep society moving forward.

Sick humor is part of this, though having grown up watching Monty Python and reading National Lampoon magazine I’m certainly guilty of enjoying it. To this day I think “Eating Raoul” is one of the greatest comedies ever.

It’s also pretty common in medicine. I’ve been involved in plenty of hospital situations that were quite unfunny, yet there are always jokes about it flying as we work.

I assume it’s a defense mechanism. Helping us cope with a bad situation as we do our best to deal with it. Using humor to put a block between the obvious realization that someday this could happen to us. To help psychologically shield us from something tragic.

Years ago I was trying to describe the plot of “Eating Raoul” and said “if you read about this sort of crime spree in a newspaper you’d be horrified. But the way it’s handled in the movie it’s hysterical.” Perhaps that’s as close to understanding sick humor as I’ll ever get. It makes the unfunny funny.

Perhaps the better phrase is the more generic “it’s human nature.” We seek relief in humor, even (maybe especially) in bad situations of our own and others.

Whether or not it’s funny depends on the person. There were plenty of people horrified by the Subway sign, enough that the owner had to change it. But there were also those who admitted they found it tasteless, but still got a laugh out of it. I’m sure the families of those lost on the Titan were justifiably upset, but the closer you get to a personal tragedy the more serious it is.

There’s a fine line, as National Lampoon put it, between funny and sick. But it’s also part of who we are.

Abiomed is recalling all Impella left-sided blood pumps in the United States over a potential safety issue when used in patients with a transcatheter aortic valve replacement (TAVR) stent – something that is not adequately addressed in the pumps’ current instructions for use (IFU).

This recall represents a “voluntary correction, not a product removal.” Impella heart pumps do not need to be returned, the U.S. Food and Drug Administration says.

Instead, the company will update the pump’s IFU to include guidance to clinicians on how to manage use of Impella in patients with TAVR.

Clinicians may continue to use the Impella devices, with the additional instructions for patients with TAVR in mind, the FDA says.

As explained in the recall notice, there is a potential risk that the Impella motor housing may come into contact with the distal stent of a TAVR, which may damage or destroy the motor’s impeller blades.

“The damaged Impella system may have reduced blood flow or pump stop, which may delay therapy or fail to provide enough support to the patient. This could be life threatening in people who require high levels of support. There is also a risk that pieces of the broken blades could enter the patient’s bloodstream,” the notice warns.

The recall covers 7895 devices distributed from May 1, 2021, to the present, including the following devices:

• Impella 5.0 Blood Pump, product number 005062
• Impella CP Blood Pump, product number 0048-0032
• Impella 2.5 Blood Pump, product number 005042
• Impella CP with SmartAssist Blood Pump, product numbers 0048-0024, 0048-0045, and 1000080
• Impella LD Blood Pump, product number 005082
• Impella 5.5 with SmartAssist Blood Pump, product numbers 0550-0008 and 1000100.

Abiomed reports 30 complaints, 26 injuries, and 4 deaths related to this issue, which has garnered a class I recall from the FDA, the most serious type.

In an urgent device correction letter sent to health care professionals in June, Abiomed says, “For a patient with TAVR who needs hemodynamic support, clinicians should factor this risk into the risk benefit analysis and are cautioned to position the Impella system carefully as directed in this notification.

“The risk of interaction is increased for oversized or under expanded frames with the distal ends not flush with the aortic wall, resulting in the distal stent structures oriented in such a way as to potentially enter the outflow window and allow contact of the end of the stent with the spinning impeller,” the letter states.

Clinicians are advised to avoid repositioning while the device is spinning and to turn the device to P0 during repositioning or any movement that could bring the outlet windows into proximity with the valve stent structures.

If low flow is observed in a patient implanted with a TAVR while on Impella heart pump support, clinicians should consider damage of the impeller and replace the Impella pump as soon as possible, the company says.

Questions about this recall can be addressed to Shashi Thoutam at 734-262-6255 and/or local clinical field staff.

Health care professionals can report adverse reactions or quality problems they experience using these devices to the FDA’s MedWatch program.

Fifth pregnancy, first baby.

After four pregnancies resulted in losses – and doing things as natural as possible and leaving it up to the birds, bees, and fate – my husband and I decided to explore in vitro fertilization (IVF).

Drugs to direct my follicles to produce more eggs, an egg retrieval procedure, genetic testing of our embryos, a quick procedure to remove a residual uterine septum from my uterus, drugs to thicken my endometrial lining to prepare my body to receive an embryo, an embryo transfer, steroids to suppress my immune system so my body would accept the pregnancy, blood thinner shots to promote blood flow to the baby, and 10 weeks of progesterone in oil shots later and we’re days away from welcoming our first baby into our lives.

In short, there’s more than one way to define “miracle baby.”

Global estimates say 48 million couples and 186 million individuals struggle with infertility. On average, 2 million infants born in the United States each year are conceived through assisted reproductive technology and the demand for treatments like IVF have doubled in the last decade.

Now the need for treatments outweighs clinician availability. “We have about 1,250 practicing fertility physicians in the U.S. to serve the whole country, which is highly inadequate,” said Eduardo Hariton, MD, a reproductive endocrinology physician in San Francisco and managing director of the U.S. Fertility Innovation Fund. “We have people that want to get care waiting 1 to 3 months to be seen.”

Dr. Hariton explains that U.S. IVF clinics are performing around 250,000 to 300,000 IVF cycles per year and need to be doing a million-plus to meet demand. This, plus the cost of fertility treatments – an average IVF cycle runs $23,500 and the majority of patients need multiple cycles to conceive – keeps the barrier to entry high.

Enter technology: New advances are on the way to help the assisted fertility process to run smoother and be less costly. “The field is really coming into an age of great progress and innovation,” added S. Zev Williams, MD, PhD, chief of the division of reproductive endocrinology and Infertility at Columbia University Irving Medical Center, New York City.

I’m personally grateful that such technology exists. Here is a look at some recent game changers in reproductive tech and what the future may hold.
 

AI will help, of course

Fertility treatments involve endless analysis, diagnosis, and recommendations – dozens if not hundreds of decisions from each physician for each patient. Human action and reaction can affect this process, Dr. Hariton explained.

For example, if he hyperstimulated a woman during the follicle growing stage of her egg retrieval and ended up with eggs too large to retrieve, Dr. Hariton said he may subconsciously be more inclined to be extra cautious with his patients the week after, and vice versa.

This is where AI can help. “Rather than me making decisions from a couple of thousands of cycles of experience, I get to leverage hundreds of thousands of cycles from different providers over different people,” said Dr. Hariton. “I get to use all the data from that patient today – her age, her weight, what happened last cycle, how she’s doing – and make a very objective decision about the optimal time to give that woman or that couple the best outcome possible.”

AI can also assist with tasks like embryo grading. “Once our embryos are made in the lab, we usually have an embryologist looking at those embryos, grading them on a three-variable scale, and then picking the nicest one for transfer,” said Dr. Hariton. Machine learning computer vision software can help doctors select the best embryo.

Many of these AI products are in trials in the United States and some AI-based technology is already being used in fertility labs, especially in other countries. “ALife recently launched a suite of products to help with their decisions during stimulation that can help with the quality KPIs [key performance indicators] in the lab,” said Dr. Hariton. “There’s also a company that does AI-based predictions of success to give patients a better estimate called Univfy.” More AI products are still in development or awaiting Food and Drug Administration clearance.
 

Robots lend a hand

Like artificial intelligence, robots can be a big help in the IVF lab. Columbia University Fertility Center recently became the first to use an articulated (ART) robot to handle precise and highly repetitive work.

“IVF, from the initial point, involves creating these special plates where embryos can grow, and you do that by making little droplets,” said Dr. Williams. “It’s very time-consuming to create tons of these little droplets for the embryos to grow.” Thus, the lab created a robot to help squirt drops of the media substance required to sustain embryos in a way that is 10 times more precise than that of a trained embryologist.

“It’s a win-win because you allow the robots to do things better than a human can and this allows the humans to do things that a robot just can’t do,” explained Dr. Williams. He and his team began using this technology in the beginning of November 2022.

Dr. Williams sees ART robots being used in many more parts of the fertility treatment journey along the way, like preparing eggs after they are retrieved and performing intracytoplasmic sperm injection (ICSI), with the robot injecting the sperm into the egg.

Launching with the plate making, said Dr. Williams, is a low stakes entry point for robotic technology in the lab. “It allows us to introduce robotics to automate and optimize each step along the way, but to do so in the safest possible way.”

Dr. Williams estimates that robots will have their hands on actual eggs and sperm in 5 years.
 

Updates in genetic testing

Currently, if a couple wants to have their embryos genetically tested, also known as preimplantation genetic testing, each embryo must be frozen, then a biopsy of that embryo is performed and sent to the lab.

“It takes time to get the results,” said Dr. Williams. “The whole time you’re waiting, you don’t know if you’re going to have any embryos that are transferable or if next month you’re going to have to do another IVF cycle.”

Columbia researchers recently developed a new in-house test that can determine if a fetus or embryo has the right number of chromosomes. This STORK (Short-read Transpore Rapid Karyotyping) can be performed without freezing embryos and sending them out, which Dr. Williams said can save couples money and time, as they won’t necessarily need to do a separate embryo transfer cycle and can transfer an embryo in the same cycle. “You can test in the morning and transfer in the afternoon,” said Dr. Williams.

The test is currently awaiting approval and will first be used to test miscarriage samples to see if embryos were genetically normal or not, which he said should cost around $200 vs. the $2,000 to $4,000 it can cost to have fetal tissue sent to the lab – and insurance doesn’t cover the procedure until after a second or third miscarriage.

This, said Dr. Williams, should be in the field in less than a year, and he estimates that the test will be used for fresh embryos in about a year and a half.
 

Sperm collection made simpler

Typically, a man delivers a sperm sample in a room at an IVF clinic or by collecting a sample at home and rushing it to the clinic before it degrades, which Dr. Williams said can happen in as little as 15 minutes.

In 2020, Dr. Williams and his team began using a custom at-home sperm collection box that houses sperm in a recyclable foam container that holds a sample cup, which is filled with special sperm-supporting media, at an angle that prevents evaporation and maintains temperature and pH. This allows patients to collect samples in the comfort of their homes and increases the clock to 3 hours.

“It’s great for the patients because it’s much more comfortable,” said Dr. Williams, who notes that having to “perform” on site can be stressful for men. Studies the team has conducted have shown sperm collected in this manner have a better success rate than those collected in the lab, and 90% of Columbia’s Fertility Center patients are now providing sperm samples this way.

Similar innovations to deliver sperm, like Protex, are now on the market, while companies like myLabBox and Legacy are offering at-home sperm testing kits to mail in for a full semen analysis.
 

At-home monitoring: More and better

Wearable reproductive health devices are also helping more women get pregnant. “I am very excited about biometric data harnessed in wearables to predict periods, ovulation, and fertility,” said Amander Clark, PhD, director of the UCLA Center for Reproductive Science, Health, and Education, Los Angeles.

The Tempdrop Fertility and Ovulation Tracker, for instance, is a wearable sensor with an accompanying charting app that helps a woman identify her most fertile days to conceive. The Bellabeat Ivy is a women’s health smart bracelet with a strong focus on tracking a woman’s cycle and fertility, pregnancy, and postnatal symptoms. And Mirvie, which is currently in development, is a blood test that will be able to predict pregnancy complications earlier.

Physicians are also looking to move as much of the lab experience as they can into a patient’s home, which streamlines processes while offering privacy and comfort. For example, Dr. Hariton, who runs a strategic venture capital fund for physicians, said his team is currently working with a company that does remote ultrasounds.

And Mira, an at-home hormone monitor, uses patented AI algorithms to accurately measure the levels of major reproductive health hormones (E3G, LH, PdG, FSH) in urine, said Meir Olcha, MD, chief medical officer at Sama Fertility. The product recently completed a clinical trial, which showed it was a viable alternative to blood serum for patients undergoing IVF.
 

Stem cells could make eggs ageless

Research shows that a woman’s egg quality decreases gradually but significantly starting at age 32 and more rapidly after 37. Sperm quality may also decrease with age. A possible workaround: Scientists are actively researching how to create eggs and sperm from stem cells.

“I think getting eggs from stem cells will happen in the future,” said Dr. Hariton, who notes that this type of technology would be a game changer in his clinic. “It will make some of the hardest diagnoses that I have – which is on a daily basis, ‘I’m so sorry, you’re in premature menopause’ or ‘I don’t think we’re going to be successful getting you pregnant with your own eggs; here are some other options like donor eggs’ – much better,” he added. And stem cells are currently being used to research causes of infertility.

Clinics like UCLA have already been making strides. “We are using stem cells to identify new genes required for reproduction and to define the role of these genes in human fertility and infertility,” said Dr. Clark, a member of the Eli and Edythe Broad Center of Regenerative Medicine and Stem Cell Research at UCLA, who recently led a study in this arena. “In vitro gametogenesis (IVG), another stem cell technology, is currently used in the research lab to understand causes of infertility.”

These stem cell-based embryo models, she said, can help researchers understand the first few days of embryo development after an embryo implants and be used to provide critical information on causes of early pregnancy loss or birth defects.

Drugs to direct my follicles to produce more eggs, an egg retrieval procedure, genetic testing of our embryos, a quick procedure to remove a residual uterine septum from my uterus, drugs to thicken my endometrial lining to prepare my body to receive an embryo, an embryo transfer, steroids to suppress my immune system so my body would accept the pregnancy, blood thinner shots to promote blood flow to the baby, and 10 weeks of progesterone in oil shots later and we’re days away from welcoming our first baby into our lives.

In short, there’s more than one way to define “miracle baby.”

Global estimates say 48 million couples and 186 million individuals struggle with infertility. On average, 2 million infants born in the United States each year are conceived through assisted reproductive technology and the demand for treatments like IVF have doubled in the last decade.

Now the need for treatments outweighs clinician availability. “We have about 1,250 practicing fertility physicians in the U.S. to serve the whole country, which is highly inadequate,” said Eduardo Hariton, MD, a reproductive endocrinology physician in San Francisco and managing director of the U.S. Fertility Innovation Fund. “We have people that want to get care waiting 1 to 3 months to be seen.”

Dr. Hariton explains that U.S. IVF clinics are performing around 250,000 to 300,000 IVF cycles per year and need to be doing a million-plus to meet demand. This, plus the cost of fertility treatments – an average IVF cycle runs $23,500 and the majority of patients need multiple cycles to conceive – keeps the barrier to entry high.

Enter technology: New advances are on the way to help the assisted fertility process to run smoother and be less costly. “The field is really coming into an age of great progress and innovation,” added S. Zev Williams, MD, PhD, chief of the division of reproductive endocrinology and Infertility at Columbia University Irving Medical Center, New York City.

I’m personally grateful that such technology exists. Here is a look at some recent game changers in reproductive tech and what the future may hold.
 

AI will help, of course

Fertility treatments involve endless analysis, diagnosis, and recommendations – dozens if not hundreds of decisions from each physician for each patient. Human action and reaction can affect this process, Dr. Hariton explained.

For example, if he hyperstimulated a woman during the follicle growing stage of her egg retrieval and ended up with eggs too large to retrieve, Dr. Hariton said he may subconsciously be more inclined to be extra cautious with his patients the week after, and vice versa.

This is where AI can help. “Rather than me making decisions from a couple of thousands of cycles of experience, I get to leverage hundreds of thousands of cycles from different providers over different people,” said Dr. Hariton. “I get to use all the data from that patient today – her age, her weight, what happened last cycle, how she’s doing – and make a very objective decision about the optimal time to give that woman or that couple the best outcome possible.”

AI can also assist with tasks like embryo grading. “Once our embryos are made in the lab, we usually have an embryologist looking at those embryos, grading them on a three-variable scale, and then picking the nicest one for transfer,” said Dr. Hariton. Machine learning computer vision software can help doctors select the best embryo.

Many of these AI products are in trials in the United States and some AI-based technology is already being used in fertility labs, especially in other countries. “ALife recently launched a suite of products to help with their decisions during stimulation that can help with the quality KPIs [key performance indicators] in the lab,” said Dr. Hariton. “There’s also a company that does AI-based predictions of success to give patients a better estimate called Univfy.” More AI products are still in development or awaiting Food and Drug Administration clearance.
 

Robots lend a hand

Like artificial intelligence, robots can be a big help in the IVF lab. Columbia University Fertility Center recently became the first to use an articulated (ART) robot to handle precise and highly repetitive work.

“IVF, from the initial point, involves creating these special plates where embryos can grow, and you do that by making little droplets,” said Dr. Williams. “It’s very time-consuming to create tons of these little droplets for the embryos to grow.” Thus, the lab created a robot to help squirt drops of the media substance required to sustain embryos in a way that is 10 times more precise than that of a trained embryologist.

“It’s a win-win because you allow the robots to do things better than a human can and this allows the humans to do things that a robot just can’t do,” explained Dr. Williams. He and his team began using this technology in the beginning of November 2022.

Dr. Williams sees ART robots being used in many more parts of the fertility treatment journey along the way, like preparing eggs after they are retrieved and performing intracytoplasmic sperm injection (ICSI), with the robot injecting the sperm into the egg.

Launching with the plate making, said Dr. Williams, is a low stakes entry point for robotic technology in the lab. “It allows us to introduce robotics to automate and optimize each step along the way, but to do so in the safest possible way.”

Dr. Williams estimates that robots will have their hands on actual eggs and sperm in 5 years.
 

Updates in genetic testing

Currently, if a couple wants to have their embryos genetically tested, also known as preimplantation genetic testing, each embryo must be frozen, then a biopsy of that embryo is performed and sent to the lab.

“It takes time to get the results,” said Dr. Williams. “The whole time you’re waiting, you don’t know if you’re going to have any embryos that are transferable or if next month you’re going to have to do another IVF cycle.”

Columbia researchers recently developed a new in-house test that can determine if a fetus or embryo has the right number of chromosomes. This STORK (Short-read Transpore Rapid Karyotyping) can be performed without freezing embryos and sending them out, which Dr. Williams said can save couples money and time, as they won’t necessarily need to do a separate embryo transfer cycle and can transfer an embryo in the same cycle. “You can test in the morning and transfer in the afternoon,” said Dr. Williams.

The test is currently awaiting approval and will first be used to test miscarriage samples to see if embryos were genetically normal or not, which he said should cost around $200 vs. the $2,000 to $4,000 it can cost to have fetal tissue sent to the lab – and insurance doesn’t cover the procedure until after a second or third miscarriage.

This, said Dr. Williams, should be in the field in less than a year, and he estimates that the test will be used for fresh embryos in about a year and a half.
 

Sperm collection made simpler

Typically, a man delivers a sperm sample in a room at an IVF clinic or by collecting a sample at home and rushing it to the clinic before it degrades, which Dr. Williams said can happen in as little as 15 minutes.

In 2020, Dr. Williams and his team began using a custom at-home sperm collection box that houses sperm in a recyclable foam container that holds a sample cup, which is filled with special sperm-supporting media, at an angle that prevents evaporation and maintains temperature and pH. This allows patients to collect samples in the comfort of their homes and increases the clock to 3 hours.

“It’s great for the patients because it’s much more comfortable,” said Dr. Williams, who notes that having to “perform” on site can be stressful for men. Studies the team has conducted have shown sperm collected in this manner have a better success rate than those collected in the lab, and 90% of Columbia’s Fertility Center patients are now providing sperm samples this way.

Similar innovations to deliver sperm, like Protex, are now on the market, while companies like myLabBox and Legacy are offering at-home sperm testing kits to mail in for a full semen analysis.
 

At-home monitoring: More and better

Wearable reproductive health devices are also helping more women get pregnant. “I am very excited about biometric data harnessed in wearables to predict periods, ovulation, and fertility,” said Amander Clark, PhD, director of the UCLA Center for Reproductive Science, Health, and Education, Los Angeles.

The Tempdrop Fertility and Ovulation Tracker, for instance, is a wearable sensor with an accompanying charting app that helps a woman identify her most fertile days to conceive. The Bellabeat Ivy is a women’s health smart bracelet with a strong focus on tracking a woman’s cycle and fertility, pregnancy, and postnatal symptoms. And Mirvie, which is currently in development, is a blood test that will be able to predict pregnancy complications earlier.

Physicians are also looking to move as much of the lab experience as they can into a patient’s home, which streamlines processes while offering privacy and comfort. For example, Dr. Hariton, who runs a strategic venture capital fund for physicians, said his team is currently working with a company that does remote ultrasounds.

And Mira, an at-home hormone monitor, uses patented AI algorithms to accurately measure the levels of major reproductive health hormones (E3G, LH, PdG, FSH) in urine, said Meir Olcha, MD, chief medical officer at Sama Fertility. The product recently completed a clinical trial, which showed it was a viable alternative to blood serum for patients undergoing IVF.
 

Stem cells could make eggs ageless

Research shows that a woman’s egg quality decreases gradually but significantly starting at age 32 and more rapidly after 37. Sperm quality may also decrease with age. A possible workaround: Scientists are actively researching how to create eggs and sperm from stem cells.

“I think getting eggs from stem cells will happen in the future,” said Dr. Hariton, who notes that this type of technology would be a game changer in his clinic. “It will make some of the hardest diagnoses that I have – which is on a daily basis, ‘I’m so sorry, you’re in premature menopause’ or ‘I don’t think we’re going to be successful getting you pregnant with your own eggs; here are some other options like donor eggs’ – much better,” he added. And stem cells are currently being used to research causes of infertility.

Clinics like UCLA have already been making strides. “We are using stem cells to identify new genes required for reproduction and to define the role of these genes in human fertility and infertility,” said Dr. Clark, a member of the Eli and Edythe Broad Center of Regenerative Medicine and Stem Cell Research at UCLA, who recently led a study in this arena. “In vitro gametogenesis (IVG), another stem cell technology, is currently used in the research lab to understand causes of infertility.”

These stem cell-based embryo models, she said, can help researchers understand the first few days of embryo development after an embryo implants and be used to provide critical information on causes of early pregnancy loss or birth defects.

Up to one in four patients who undergo metabolic/bariatric surgery have less than 20% weight loss and patients need additional strategies to help them reach their goals.

In the new BARI-OPTIMISE trial, patients with poor weight loss after such surgery were randomized to the glucagonlike peptide–1 (GLP-1) agonist liraglutide 3.0 mg/day or placebo. Liraglutide was safe and well-tolerated and led to a clinically meaningful 8% further reduction in bodyweight, compared with placebo, report Jessica Mok, BMBS, MPhil, University College London and colleagues, in their study published online in JAMA Surgery.

Weight loss in BARI-OPTIMISE (–9.2 kg or –20 lb) was greater than the weight loss in the earlier GRAVITAS trial of 80 patients with persistent or recurrent type 2 diabetes randomized to liraglutide 1.8 mg/day or placebo, Dr. Mok and colleagues note. And more patients in BARI-OPTIMISE than in GRAVITAS lost 5% or more of their baseline weight (72% vs. 46%).

“Our findings therefore suggest that liraglutide, 3.0 mg, may have a role in the treatment of people with poor weight loss following metabolic surgery,” they write.  

However, newer gut hormone–based therapies with greater efficacy than liraglutide 3.0 mg (for example, semaglutide and tirzepatide) are emerging, they add.

Therefore, “randomized clinical trials investigating the efficacy of novel pharmaceutical agents will be needed to generate the evidence required to deliver individualized precision-medicine approaches to patients with obesity and suboptimal weight loss following metabolic surgery,” the researchers urge.
 

‘Extremely welcome tools for severe obesity’

“The additional weight loss with associated favorable metabolic changes achieved with liraglutide reported in [the BARI-OPTIMISE and GRAVITAS trials] is extremely welcomed with the new antiobesity medications ... adding another effective tool in the toolbox for the treatment of severe obesity,” Paulina Salminen, MD, PhD, Turku (Finland) University Hospital, and Ali Aminian, MD, Cleveland Clinic, write in an accompanying editorial.

However, they also point to limitations of the current trial.

Almost all patients (65 of 70 [93%]) underwent laparoscopic sleeve gastrectomy in BARI-OPTIMISE. However, “there are safe and more effective surgical options that can be considered in patients with suboptimal initial clinical response or recurrent weight gain” after laparoscopic sleeve gastrectomy, such as “conversion to Roux-en-Y gastric bypass (RYGB), duodenal switch, or single-anastomosis duodeno-ileal bypass,” they note.

The small number of patients and low follow-up rate of 81% (57 of 70 patients) for the short intervention are other limitations.

“In treating a patient with ischemic heart disease, a combination of lifestyle intervention, risk factor modification, pharmacotherapy, coronary stenting, and open-heart surgery may be needed,” note the editorialists. “A very similar concept would be applicable in the management of severe obesity.”

In the past, they add, there was not much progress with combination therapies for obesity because of a lack of effective antiobesity medications.

However, “with the better availability of potent [antiobesity medications] now and in the near future, the practice of combination therapy will grow as [metabolic and bariatric surgery] and [antiobesity medications] work in synergy in both treating severe obesity and hopefully also in enabling increased access to effective obesity treatment,” Dr. Salminen and Dr. Aminian speculate.

“Hopefully, based on findings of future studies and the use of global uniform criteria for evaluating treatment outcomes,” the editorialists conclude, “we can develop practice guidelines to assist and optimize phenotype-tailored multimodal treatment of this heterogeneous chronic disease of severe obesity.”
 

Most patients had severe obesity, sleeve gastrectomy

Individuals with poor weight loss after surgery have increased appetite coupled with an unfavorable gut hormone profile, including lower circulating GLP-1 levels, Dr. Mok and colleagues note.

In 2018 and 2019, they recruited and randomized 70 adults who had had metabolic surgery at two hospitals in London at least a year earlier and had 20% or less weight loss, compared with the day of surgery, as well as a suboptimal nutrient-stimulated GLP-1 response.

Patients were excluded if they had type 1 diabetes or were taking a GLP-1 agonist, insulin, or other medications that can affect weight, among other criteria.

The mean age of patients was 48 years, and 74% were women; 13% had type 2 diabetes.

Participants had a mean weight of 120 kg, and a mean body mass index of 43 kg/m² (57% had a BMI ≥ 40 kg/m²). Almost all patients (93%) had had sleeve gastrectomy and 7% had RYGB.

On average, they had surgery 4.3 years earlier and had lost 7% of their initial weight.

Patients were randomized 1:1 to receive liraglutide 3.0 mg or placebo daily for 24 weeks. All patients received dietary counseling and aimed for a 500 kcal/day energy deficit. They were encouraged to do a minimum of 150 minutes of moderate to vigorous exercise each week.

The primary endpoint, percentage change in body weight from baseline to week 24, was –8.8% with liraglutide versus –0.53% with placebo.

Adverse effects were predominantly gastrointestinal in nature and were more frequent with liraglutide (80%) than placebo (57%). There were no serious adverse events.

This study was funded by the Sir Jules Thorn Charitable Trust and the National Institute for Health and Care Research. Novo Nordisk provided the liraglutide and placebo pens. Author disclosures are listed with the article. Dr. Salminen has reported receiving personal fees from Novo Nordisk. Dr. Aminian has reported receiving received grants and personal fees from Medtronic and Ethicon.

Despite my best efforts to cultivate acquaintances across a broader age group, my social circle still has the somewhat musty odor of septuagenarians. We try to talk about things beyond the weather and grandchildren but pain scenarios surface with unfortunate frequency. Arthritic joints ache, body parts wear out or become diseased and have to be removed or replaced. That stuff can hurt.

There are two pain-related themes that seem to crop up more frequently than you might expect. The first is the unfortunate side effects of opioid medication – most often gastric distress and vomiting, then of course there’s constipation. They seem so common that a good many of my acquaintances just plain refuse to take opioids when they have been prescribed postoperatively because of their vivid memories of the consequences or horror stories friends have told.

The second theme is the general annoyance with the damn “Please rate your pain from one to ten” request issued by every well-intentioned nurse. Do you mean the pain I am having right now, this second, or last night, or the average over the last day and a half? Or should I be comparing it with when I gave birth 70 years ago, or when I stubbed my toe getting out of the shower last week? And then what are you going to do with my guesstimated number?

It may surprise some of you that 40 years ago there wasn’t a pain scale fetish. But a few observant health care professionals realized that many of our patients were suffering because we weren’t adequately managing their pain. In postoperative situations this was slowing recovery and effecting outcomes. Like good pseudoscientists, they realized that we should first quantify the pain and the notion that no pain should go unrated came into being. Nor should pain go untreated, which is too frequently interpreted as meaning unmedicated.

Pain is a complex, multifaceted phenomenon. Distilling a person’s pain experience to a single number doesn’t make sense, nor does reflexly reaching for a prescription.

For example a systematic review of 61 studies of juvenile idiopathic arthritis (JIA) published in the journal Pediatric Rheumatology found that there was positive relationship between pain and a child’s belief that pain causes harm, disability, and lack of control. Not surprisingly, stress was also associated with pain intensity.

It is a long paper and touches on numerous other associations of varying degrees of strength between parental, social, and other external factors. But, in general, they were not as consistent as those related to a child’s beliefs.

Before, or at least at the same time, we treat a patient’s pain, we should learn more about that patient – his or her concerns, beliefs, and stressors. You and I may have exactly the same hernia operation, but if you have a better understanding of why you are going to feel uncomfortable after the surgery, and understand that not every pain is the result of a complication, I suspect you are more likely to complain of less pain.

The recent JIA study doesn’t claim to suggest therapeutic methods. However, one wonders what the result would be if we could somehow alter a patient’s belief system so that he or she no longer sees pain as always harmful, nor does the patient see himself or herself as powerless to do anything about the pain. To do this experiment we must follow up our robotic request to “rate your pain” with a dialogue in which we learn more about the patient. Which means probing believes, fears, and stressors.

You can tell me this exercise would be unrealistic and time consuming. But I bet in the long run it will save time. Even if it doesn’t it is the better way to manage pain.

Dr. Wilkoff practiced primary care pediatrics in Brunswick, Maine, for nearly 40 years. He has authored several books on behavioral pediatrics, including “How to Say No to Your Toddler.” Other than a Littman stethoscope he accepted as a first-year medical student in 1966, Dr. Wilkoff reports having nothing to disclose.

Before, or at least at the same time, we treat a patient’s pain, we should learn more about that patient – his or her concerns, beliefs, and stressors. You and I may have exactly the same hernia operation, but if you have a better understanding of why you are going to feel uncomfortable after the surgery, and understand that not every pain is the result of a complication, I suspect you are more likely to complain of less pain.

The recent JIA study doesn’t claim to suggest therapeutic methods. However, one wonders what the result would be if we could somehow alter a patient’s belief system so that he or she no longer sees pain as always harmful, nor does the patient see himself or herself as powerless to do anything about the pain. To do this experiment we must follow up our robotic request to “rate your pain” with a dialogue in which we learn more about the patient. Which means probing believes, fears, and stressors.

You can tell me this exercise would be unrealistic and time consuming. But I bet in the long run it will save time. Even if it doesn’t it is the better way to manage pain.

Despite my best efforts to cultivate acquaintances across a broader age group, my social circle still has the somewhat musty odor of septuagenarians. We try to talk about things beyond the weather and grandchildren but pain scenarios surface with unfortunate frequency. Arthritic joints ache, body parts wear out or become diseased and have to be removed or replaced. That stuff can hurt.

There are two pain-related themes that seem to crop up more frequently than you might expect. The first is the unfortunate side effects of opioid medication – most often gastric distress and vomiting, then of course there’s constipation. They seem so common that a good many of my acquaintances just plain refuse to take opioids when they have been prescribed postoperatively because of their vivid memories of the consequences or horror stories friends have told.

The second theme is the general annoyance with the damn “Please rate your pain from one to ten” request issued by every well-intentioned nurse. Do you mean the pain I am having right now, this second, or last night, or the average over the last day and a half? Or should I be comparing it with when I gave birth 70 years ago, or when I stubbed my toe getting out of the shower last week? And then what are you going to do with my guesstimated number?

It may surprise some of you that 40 years ago there wasn’t a pain scale fetish. But a few observant health care professionals realized that many of our patients were suffering because we weren’t adequately managing their pain. In postoperative situations this was slowing recovery and effecting outcomes. Like good pseudoscientists, they realized that we should first quantify the pain and the notion that no pain should go unrated came into being. Nor should pain go untreated, which is too frequently interpreted as meaning unmedicated.

Pain is a complex, multifaceted phenomenon. Distilling a person’s pain experience to a single number doesn’t make sense, nor does reflexly reaching for a prescription.

For example a systematic review of 61 studies of juvenile idiopathic arthritis (JIA) published in the journal Pediatric Rheumatology found that there was positive relationship between pain and a child’s belief that pain causes harm, disability, and lack of control. Not surprisingly, stress was also associated with pain intensity.

Daily use of low-dose aspirin offers no significant protection against stroke and was linked to a higher rate of bleeding in the brain, according to new research published in JAMA.

The research matches other evidence advising that healthy older adults without a history of heart conditions or warning signs of stroke should not take low-dose aspirin. 

The findings also support the recommendation from the U.S. Preventive Services Task Force that low-dose aspirin should not be prescribed for preventing a first heart attack or stroke in healthy older adults, The New York Times reported.

“We can be very emphatic that healthy people who are not on aspirin and do not have multiple risk factors should not be starting it now,” said Randall Stafford, MD, of Stanford (Calif.) University, who was not involved in the study, in the Times.

It’s not as clear for others, he said.

“The longer you’ve been on aspirin and the more risk factors you have for heart attacks and strokes, the murkier it gets,” he said.

Some cardiac and stroke experts say daily aspirin should remain part of the regimen for people who have had a heart attack or stroke.

The JAMA report was based on data from a randomized control trial of 19,000 people from Australia and America. Participants were over the age of 70 and did not have heart disease. 

The data covered an average of almost 4.7 years and revealed that aspirin lowered the rate of ischemic stroke but not significantly. An ischemic stroke happens when a clot forms in a blood vessel that sends blood to the brain. 

There was also a 38% higher rate of brain bleeds for people who took aspirin daily, compared with those who took a placebo.

The Times wrote, “In the past, some doctors regarded aspirin as something of a wonder drug, capable of protecting healthy patients against a future heart attack or stroke. But recent studies have shown that the powerful drug has limited protective power among people who have not yet had such an event, and it comes with dangerous side effects.”
