As the famous saying goes, “laughter is the best medicine.”

So it’s no surprise that humor is a great way to connect with different people and across various groups.

Memes are usually conveyed as images and texts that communicate ideas or thoughts. A meme, or “imitated thing” (translation from the Greek mimeme), was reappropriated from Richard Dawkins in his book The Selfish Gene; we can characterize “meme” with the word “gene” insofar as both self-replicate and are translated from person to person.

I am a big fan of memes. In fact, I can confidently say that one-third of my camera roll is dedicated to saved memes from Facebook, Instagram, and friends. Shameless to say, I’m also part of a few online groups dedicated to memes. They are relatable, as well as quick and fun ways to make light of an otherwise dull or upsetting situation.

Memes are contagious. From the moment they are created, they can be shared from one person to another, be edited or changed to adapt to the current situation, and become viral. They can be used to augment a conversation or replace the need for text communication entirely – in a sense, they are an entire language in and of themselves. They are constantly undergoing selection, repacking, and filtration. As a result, the most popular, successful, and, usually, relatable meme comes out on top, whereas the others fall behind and become “extinct.”

Memes generally adopt a form of word- or image-play that resonates well with people. The type of content varies from general lighthearted harmless animal humor to wry political and/or social commentary. They can be nearly universal or target specific groups (for example, students).

The popularity of memes depends on two factors: likability and “viralability.” Likability refers to how stimulating or engaging the content is, whereas “viralability” refers to the ability of the content to create a similar effect of user engagement across multiple people. Both factors are dynamic and can be quantified on the basis of the number of likes, shares, and/or comments.

In a content analysis of 1,000 memes on Facebook, researchers found that affiliative and aggressive humor styles were the most prevalent. Affiliative humor refers to a style of banter or joke that portrays others in a positive light, whereas aggressive humor achieves the opposite (that is, portrays others in a negative light). Interestingly, the type of humor that achieved the average most likes and shares was self-defeating humor (that is, disparaging one’s own situation in a negative perspective).

Self-defeating memes are suggested to have higher meme fitness. Meme fitness refers to the replicability of a meme. In this context, self-defeating memes have a unique ability to resonate with peoples’ thoughts and feelings in a sarcastic way and create laughter in contexts of general hardships (for example, failed relationships, academic hardships, or general life weaknesses). In a way, I’ve found that self-defeating memes offer a branch of support; to know that I am not going through certain problems alone, and that others can understand these difficulties, is comforting.

Memes can target emotional pain, neutralize the threat, and turn discomfort into a discourse of playfulness and warmth. Especially during times of great uncertainty, a bit of banter and wry humor may be just what we need to make light of difficult situations.

EVIDENCE SUMMARY

General exercise offers benefit …at least for chronic LBP

A 2017 systematic review of 4 systematic reviews and 50 RCTs (122 total trials) evaluated general exercise vs usual care for acute (< 4 weeks), subacute (4 to 12 weeks), or chronic (≥ 12 weeks) LBP with or without radiculopathy in adults.¹ Exercise was not consistently associated with decreased pain in acute or subacute LBP. For chronic LBP, 3 RCTs (n = 200) associated exercise with decreased pain (weighted mean difference [WMD] = –9.2 on a 0-100 point visual acuity scale; 95% CI, –16.0 to –2.4) and improved function (WMD = –12.4 on the Oswestry Disability Index; 95% CI, –23.0 to –1.7) at short-term follow-up (≤ 3 months). This effect was found to decrease at long-term (≥ 1 year) follow-up (WMD for pain = –4.9; 95% CI, –10.5 to 0.6 and WMD for function = –3.2; 95% CI, 6.0 to –0.4). In a meta-analysis of 10 studies (n = 1992) included in this systematic review, exercise was associated with a lower likelihood of work disability (odds ratio, 0.66; CI, 0.48 to 0.92) at 12 months.¹

Yoga, Pilates, and motor control exercise: Your results may vary

Several reviews have explored the effects of specific exercise modalities on LBP. A 2017 meta-analysis of 9 RCTs in the United States, United Kingdom, and India of nonpregnant adults (≥ 18 years old) with chronic LBP (N = 810) found that yoga (any tradition of yoga with a physical component) vs no exercise demonstrated a statistically, but not clinically, significant decrease in pain at 3 to 4 months (mean difference [MD] = –4.6 on a 0-100 point scale; 95% CI, –7.0 to –2.1), 6 months (MD = –7.8; 95% CI, –13.4 to –2.3), and 12 months (MD = –5.4; 95% CI, –14.5 to –3.7). Clinically significant pain benefit was considered a change of 15 or more points.²

A 2015 meta-analysis of RCTs (10 trials; N = 510) comparing the effects of Pilates (a form of body conditioning involving isometric contractions and core exercises focusing on stability) vs minimal intervention on chronic (> 12 weeks) LBP in nonpregnant adults (≥ 16 years old) found low-quality evidence for decreased pain at short-term follow-up (≤ 3 months; MD = –14.1 on a 0-100 point scale; 95% CI, –18.9 to –9.2). There was moderate-quality evidence for decreased pain at intermediate follow-up (3-12 months; MD = –10.5; 95% CI, –18.5 to –2.6).³

A 2016 systematic review evaluated motor control exercise (MCE; a form of exercise that focuses on trunk muscle control and coordination) in adults (≥ 16 years old) with chronic LBP (≥ 12 weeks). There was low- to moderate-quality evidence that, compared to minimal intervention, MCE decreases pain at short-term (≤ 6 months; 4 RCTs; MD = –10.0 on a 0-100 point scale; 95% CI, –15.7 to –4.4), intermediate (6-12 months; 4 RCTs; MD = –12.6; 95% CI, –20.5 to –4.7), and long-term follow-up (> 12 months; 3 RCTs; MD = –13.0; 95% CI, –18.5 to –7.4). When comparing MCE to general exercise, there were no clinically significant differences in pain or disability at intermediate and long-term follow-up.⁴Common limitations included heterogeneity of intervention methodology, inability to blind results, inability to assess cointerventions, and in some cases, small sample sizes of trials.

Recommendations from others

The 2017 American College of Physicians (ACP) clinical practice guideline on noninvasive treatments for LBP does not recommend exercise therapy in acute or subacute LBP; recommended therapies include superficial heat, massage, acupuncture, or spinal manipulation.⁵ The ACP recommends general exercise, yoga, tai chi, or MCE for chronic LBP, in addition to multidisciplinary rehabilitation, acupuncture, mindfulness-based stress reduction, progressive relaxation, biofeedback, laser therapy, operant therapy, cognitive behavioral therapy, or spinal manipulation.

The 2017 US Department of Veterans Affairs and US Department of Defense clinical practice guideline on treatment of LBP notes insufficient evidence for benefit of clinician-guided exercise therapy in acute LBP.⁶ For chronic LBP, clinician-directed exercise, yoga, tai chi, or Pilates is recommended.

Editor’s takeaway

Convincing evidence demonstrates that exercise modestly improves chronic LBP—but only modestly (4% to 15%), and not in acute LBP. This small magnitude of effect may disappoint expectations, but exercise remains among our better interventions for this common chronic problem. Few—if any—interventions have proven better, and exercise has beneficial side effects, a low cost, and widespread availability.

Dementia remains a major cause of disability in older adults. In addition, it places a strain on family members and other caregivers taking care of these patients.

It is estimated that by the year 2060, 13.9 million Americans over the age of 65 will be diagnosed with dementia. Few good treatments are currently available.

Earlier this year, the American Psychological Association (APA) Task Force issued clinical guidelines “for the Evaluation of Dementia and Age-Related Cognitive Change.” While these 16 guidelines are aimed at psychologists, primary care doctors are often the first ones to evaluate a patient who may have dementia. As a family physician, I find having these guidelines especially helpful.
 

Neuropsychiatric testing and defining severity and type

This new guidance places emphasis on neuropsychiatric testing and defining the severity and type of dementia present.

Over the past 2 decades, diagnoses of mild neurocognitive disorders have increased, and this, in part, is due to diagnosing these problems earlier and with greater precision. It is also important to know that biomarkers are being increasingly researched, and it is imperative that we stay current with this research.

Cognitive decline may also occur with the coexistence of other mental health disorders, such as depression, so it is important that we screen for these as well. This is often difficult given the behavioral changes that can arise in dementia, but, as primary care doctors, we must differentiate these to treat our patients appropriately.
 

Informed consent

Informed consent can become an issue with patients with dementia. It must be assessed whether the patient has the capacity to make an informed decision and can competently communicate that decision.

The diagnosis of dementia alone does not preclude a patient from giving informed consent. A patient’s mental capacity must be determined, and if they are not capable of making an informed decision, the person legally responsible for giving informed consent on behalf of the patient must be identified.

Patients with dementia often have other medical comorbidities and take several medications. It is imperative to keep accurate medical records and medication lists. Sometimes, patients with dementia cannot provide this information. If that is the case, every attempt should be made to obtain records from every possible source.
 

Cultural competence

The guidelines also stress that there may be cultural differences when applying neuropsychiatric tests. It is our duty to maintain cultural competence and understand these differences. We all need to work to ensure we control our biases, and it is suggested that we review relevant evidence-based literature.

While ageism is common in our society, it shouldn’t be in our practices. For these reasons, outreach in at-risk populations is very important.
 

Pertinent data

The guidelines also suggest obtaining all possible information in our evaluation, especially when the patient is unable to give it to us.

Often, as primary care physicians, we refer these patients to other providers, and we should be providing all pertinent data to those we are referring these patients to. If all information is not available at the time of evaluation, follow-up visits should be scheduled.

If possible, family members should be present at the time of visit. They often provide valuable information regarding the extent and progression of the decline. Also, they know how the patient is functioning in the home setting and how much assistance they need with activities of daily living.
 

Caretaker support

Another important factor to consider is caretaker burnout. Caretakers are often under a lot of stress and have high rates of depression. It is important to provide them with education and support, as well as resources that may be available to them. For some, accepting the diagnosis that their loved one has dementia may be a struggle.

As doctors treating dementia patients, we need to know the resources that are available to assist dementia patients and their families. There are many local organizations that can help.

Also, research into dementia is ongoing and we need to stay current. The diagnosis of dementia should be made as early as possible using appropriate screening tools. The sooner the diagnosis is made, the quicker interventions can be started and the family members, as well as the patient, can come to accept the diagnosis.

As the population ages, we can expect the demands of dementia to rise as well. Primary care doctors are in a unique position to diagnose dementia once it starts to appear.

Dementia remains a major cause of disability in older adults. In addition, it places a strain on family members and other caregivers taking care of these patients.

It is estimated that by the year 2060, 13.9 million Americans over the age of 65 will be diagnosed with dementia. Few good treatments are currently available.

Earlier this year, the American Psychological Association (APA) Task Force issued clinical guidelines “for the Evaluation of Dementia and Age-Related Cognitive Change.” While these 16 guidelines are aimed at psychologists, primary care doctors are often the first ones to evaluate a patient who may have dementia. As a family physician, I find having these guidelines especially helpful.
 

Neuropsychiatric testing and defining severity and type

This new guidance places emphasis on neuropsychiatric testing and defining the severity and type of dementia present.

Over the past 2 decades, diagnoses of mild neurocognitive disorders have increased, and this, in part, is due to diagnosing these problems earlier and with greater precision. It is also important to know that biomarkers are being increasingly researched, and it is imperative that we stay current with this research.

Cognitive decline may also occur with the coexistence of other mental health disorders, such as depression, so it is important that we screen for these as well. This is often difficult given the behavioral changes that can arise in dementia, but, as primary care doctors, we must differentiate these to treat our patients appropriately.
 

Informed consent

Informed consent can become an issue with patients with dementia. It must be assessed whether the patient has the capacity to make an informed decision and can competently communicate that decision.

The diagnosis of dementia alone does not preclude a patient from giving informed consent. A patient’s mental capacity must be determined, and if they are not capable of making an informed decision, the person legally responsible for giving informed consent on behalf of the patient must be identified.

Patients with dementia often have other medical comorbidities and take several medications. It is imperative to keep accurate medical records and medication lists. Sometimes, patients with dementia cannot provide this information. If that is the case, every attempt should be made to obtain records from every possible source.
 

Cultural competence

The guidelines also stress that there may be cultural differences when applying neuropsychiatric tests. It is our duty to maintain cultural competence and understand these differences. We all need to work to ensure we control our biases, and it is suggested that we review relevant evidence-based literature.

While ageism is common in our society, it shouldn’t be in our practices. For these reasons, outreach in at-risk populations is very important.
 

Pertinent data

The guidelines also suggest obtaining all possible information in our evaluation, especially when the patient is unable to give it to us.

Often, as primary care physicians, we refer these patients to other providers, and we should be providing all pertinent data to those we are referring these patients to. If all information is not available at the time of evaluation, follow-up visits should be scheduled.

If possible, family members should be present at the time of visit. They often provide valuable information regarding the extent and progression of the decline. Also, they know how the patient is functioning in the home setting and how much assistance they need with activities of daily living.
 

Caretaker support

Another important factor to consider is caretaker burnout. Caretakers are often under a lot of stress and have high rates of depression. It is important to provide them with education and support, as well as resources that may be available to them. For some, accepting the diagnosis that their loved one has dementia may be a struggle.

As doctors treating dementia patients, we need to know the resources that are available to assist dementia patients and their families. There are many local organizations that can help.

Also, research into dementia is ongoing and we need to stay current. The diagnosis of dementia should be made as early as possible using appropriate screening tools. The sooner the diagnosis is made, the quicker interventions can be started and the family members, as well as the patient, can come to accept the diagnosis.

As the population ages, we can expect the demands of dementia to rise as well. Primary care doctors are in a unique position to diagnose dementia once it starts to appear.

This month’s cover story, “A 4-pronged approach to foster healthy aging in older adults,” by Wilson and colleagues (page 376) provides a wealth of information about aspects of healthy aging that we should consider when we see our older patients. After reading this manuscript, I was a bit overwhelmed by the amount of information presented and, more so, by the thought of attempting to incorporate into my practice all of the possible screenings and interventions available to help older adults improve and maintain their health.

There is no debate about the importance of issues such as diet, exercise and mobility, mental health and cognition, vision and hearing, and strong social connections for maintaining health as we age. The difficulty comes in deciding how to spend our limited time with older patients during office encounters. Most older adults have several chronic diseases that need our attention, and they often have various medications that need to be monitored for effectiveness and safety, which can be time consuming. And, of course, we need to take time to screen for cardiovascular risk and cancer, too. Where to start?

Dr. Wilson’s solution makes sense to me: Take advantage of the annual wellness visit to discuss diet, exercise, mental health, vision and hearing, and social relationships. I am not so sure, however, if using formal screening instruments is the best way to do this, especially since there is no strong research that demonstrates improved patient-relevant outcomes using screening instruments, except, perhaps, for periodically screening for anxiety and depression.

It may be effective to use the “chat technique” and ask open-ended questions, such as: How are things going for you?

It may be as effective to use what I will call the “chat technique.” Start with open-ended questions and statements, such as: “How are things going for you?” “Tell me about your family.” “What do you do for physical activity?” and “How has your mood been lately?”

An excellent complement to the chat technique is the goal-setting approach championed by geriatrician and family physician Jim Mold.¹ His premise is that health itself is not the most important goal for most people, but rather a means to an end. That end is very specific to every person. An elderly, frail woman’s main life goal, for example, might be to remain in her own home for as long as possible or to live long enough to attend her great-grandson’s wedding.

Goal setting provides an excellent context for true shared decision-making. I agree with Dr. Wilson’s closing statement:

“As family physicians, it is important to capitalize on longitudinal relationships with patients and begin educating younger patients using this multidimensional framework to promote living ‘a productive and meaningful life’at any age.”

Background: A large proportion of Italian patients with COVID-19 presented with symptoms, most commonly cough, fever, dyspnea, myalgias, anosmia, and gastrointestinal symptoms. Information is lacking on persistent symptoms after recovery.

From April 21 to May 29, 2020, 179 patients were potentially eligible; 143 ultimately were included. During hospitalization, 72.7% of participants had evidence of interstitial pneumonia. Patients were assessed a mean of 60.3 days after onset of the first COVID-19 symptom. Only 18 (12.6%) were completely free of any COVID-19–related symptoms, 32% had one or two symptoms, and 55% had three or more. Worsened quality of life was observed among 44.1% of patients.

Bottom line: 87.4% of patients who had recovered from COVID-19 reported persistence of at least one symptom, particularly fatigue and dyspnea.

A survey of more than 12,000 women of reproductive age found that one in three had experienced changes to their menstrual cycles and symptoms during the COVID-19 pandemic. Noticeably higher stress levels than prepandemic benchmarks could be affecting menstruation.

This has implications for women trying to conceive or struggling with infertility, said Shannon M. Malloy, a research and data associate with Ovia Health, a women’s and family health technology company in Boston. Ms. Malloy presented this study at the American Society of Reproductive Medicine’s 2021 meeting.

COVID-19 has introduced new psychosocial, interpersonal, and environmental stressors. The pandemic is “one of the most stressful, collectively experienced disasters modern society has ever seen,” said Ms. Malloy. Once imagined as an explicit event in time, COVID-19 has ingrained itself into daily life for the foreseeable future.

Research has shown that chronic, long-term stress produces high cortisol levels, which can alter endocrinology and regulation of menstrual cycles. This can make family building even more challenging, said Ms. Malloy. Physicians and other providers have always taken stress into account when managing patients, but never at this level of chronic, episodic stress, she said.
 

Survey examines impact on ART

Ovia Health decided to investigate the relationship between perceived stress and menstrual cycle and symptom changes during the COVID-19 pandemic, to see how it might affect assisted reproductive technology (ART).

From March 2020 to April 2021, users of Ovia Health’s Fertility mobile application in the United States took part in a survey. Items captured changes in menstruation pattern and symptomatology and included the Perceived Stress Scale 4-item version (PSS-4). A paired t-test evaluated differences between groups (menstrual changes versus no menstrual changes). The survey asked participants what changes they noticed in their menstrual cycle and why they thought cycle patterns or symptoms changed.
 

One-third report changes in cycle, symptoms

Among 12,302 respondents, 1 in 3 (36%) reported changes in cycle or symptoms. Eighty-seven percent said that their cycle started early or late. Twenty-nine percent reported stronger symptoms during menstruation such as low back pain, cramping, or discharge changes, and 27% said bleeding was heavier during periods.

These results are similar to other studies investigating the affect of episodic stress on menstruation, said Ms. Malloy.

Those who reported menstrual cycle or symptom changes scored higher on average on the PSS-4 compared with those who didn’t report any changes (8.5 v. 8.3, respectively, P < .05). PSS-4 scores across the board were notably higher in all respondents, regardless of cycle/symptom irregularity, compared with prepandemic benchmarking in similar populations.

Slightly more than half (55%) thought stress contributed to their menstrual cycle pattern and/or symptom changes, whereas 33% pointed to changes in mental health, such as depression or anxiety. “Interestingly, many users believed the COVID-19 vaccine impacted their menstrual cycle symptom changes,” said Ms. Malloy.
 

No definitive link between vaccine, menstruation

While known side effects of the vaccine include sore arm, fever, fatigue, and myalgia, some women have reported changes in their menstrual cycle, Mark P. Trolice, MD, professor of obstetrics and gynecology at the University of Central Florida and director of the IVF Center in Orlando, said in an interview.

“Vaccination reaction from the immune response rather than the vaccine may be the implicating factor,” said Dr. Trolice, who was not involved in the study.

Currently, there’s no direct link between the vaccine and subsequent effects on menstruation, he continued. “Most women experience resumption of normal intervals 1 month following vaccination. Further, there is no credible evidence that links the vaccine to infertility.

“Nevertheless, research in this area is vital and underway,” he added.
 

Physicians can help with stress

Menstrual cycle disruption is especially frustrating for women trying to build a family, said Ms. Malloy. Providers may be observing more menstrual irregularity in their patient populations, and seeing more patients struggle to conceive on their own, turning to ART.

Providers can’t make COVID-19 go away, but they could help patients by doing a better job of integrating mental health screening, connecting patients to treatments that optimize conception and fertility treatment outcomes, said Ms. Malloy.

The survey was limited in that its questions didn’t consider proper diagnostic criteria for irregularity, versus self-reported changes. But it does highlight the need for more research on the pandemic’s affect on menstruation and the vaccine on menstruation, said Ms. Malloy. “The National Institutes of Health in August committed $1.6 million to explore this connection. We’re looking forward to seeing what their results are.”

Physicians could be doing a better job of counseling patients with obesity and overweight on weight loss and fertility. A study of 48 women seeking infertility care at a large academic center found that less than half received advice on weight loss from their primary ob.gyn. prior to referral for infertility treatment.

Patients are thinking about this – many attempt to lose weight independently of support from their health care providers, said lead study author Margaret R. O’Neill, MD, a resident at the University of Massachusetts Medical Center in Worcester. Dr. O’Neill discussed these results at the American Society of Reproductive Medicine’s 2021 meeting.

Nearly half of all U.S. women of reproductive age have overweight or obesity, with a body mass index of >25 kg/m². Menstrual irregularity, ovulatory dysfunction, reduced fecundity, and lower efficacy of infertility treatment are some of the consequences of obesity on fertility, said Dr. O’Neill. Obesity also affects the health of expectant mothers and fetuses, increasing the likelihood of gestational diabetes, preterm delivery, and preeclampsia, and increased incidence of fetal anomalies.

“Unfortunately, even though the prevalence of obesity has been increasing substantially in our country, there’s not excellent rates of this being addressed by physicians,” said Dr. O’Neill. BMI is often left out of documentation and rates of referrals to weight loss specialists are also low.

Conversations have been taking place about IVF centers instituting different BMI cutoffs for certain types of assisted reproductive technology, she noted.

Dr. O’Neill and her colleagues undertook a survey to see what advice community providers were dispensing about weight management on fertility.
 

Infertility specialists offer the most guidance

The prospective study included 48 nonpregnant women of reproductive age women presenting for IVF who needed an anesthesia consultation because of elevated BMI (> 35) prior to initiation of IVF. Mean age was 36 years and mean BMI was 38.5. More than 70% of the patients were White and they were predominantly English speakers.

All participants had attempted weight loss, including an attempt in the last year, and 93.8% reported trying to lose weight in the last year. On average, patients weighed about 20 pounds less than their heaviest adult weight. Nineteen percent of the participants were at their heaviest adult weight.

While 60% said they’d received weight loss/infertility counseling by any health care provider, just 41.7% reported that their primary ob.gyn. counseled them about weight loss before referring them for treatment. Infertility specialists seem to provide the most assistance: Nearly 70% of the respondents said they’ve been counseled by these providers.

Women with a higher-than-average BMI (39) were more likely to report a referral to weight loss counseling compared with women not referred (37.9, P = .2). 

Investigators also asked patients about their knowledge of obesity and its relationship to other health conditions. About 90% understood that infertility and excess weight were related. Overall, they were less sure about the link between obesity and still birth, breast cancer, and birth defects. Only 37% were able to identify a normal BMI range.
 

Avoiding a touchy subject

BMI is a highly sensitive area for many women, despite its detrimental effect on fertility, Mark P. Trolice, MD, professor of obstetrics and gynecology at the University of Central Florida and director of the IVF Center in Orlando, said in an interview.

“By the time their journey has led them to an infertility specialist, most women are very anxious to begin treatment,” said Dr. Trolice, who was not involved in the survey. These patients, however, could interpret any medical advice to achieve a more optimal BMI and healthier lifestyle as a negative judgment that could delay their goal of having a healthy child, he said.

Physicians in turn may avoid these conversations because they don’t want to encourage the ire of patients and/or risk a negative online rating review, he added.

Don’t say ‘just lose weight’

When asked what type of counseling works best, many said that nonspecific recommendations such as “you need to lose weight” or “exercise more” were the least helpful. Targeted advice such as “avoid eating at night and take walks every day,” works more effectively. “Any kind of referral to a bariatrics team or weight loss program was seen as helpful by patients,” said Dr. O’Neill.

Suggestions that considered the difficulty of this process, such as seeking therapy, were also helpful. “Patients appreciated empathy, compassion, and encouragement” from their physicians, she said.
 

The role of physicians in weight loss

Physicians can make a difference. Studies show that patients who received weight loss counseling were more likely to attempt weight loss and report clinically significant weight loss.

The American College of Obstetricians and Gynecologists and ASRM recommend counseling patients with overweight and obesity to lose weight before getting pregnant. A modest weight loss of 10% is associated with improved ovulatory function and higher pregnancy rates, said Dr. O’Neill.

“Appropriately, the infertility specialist should strongly recommend [that women who are obese] obtain a more optimal BMI prior to fertility treatment. While there is no guarantee of decreased infertility and decreased pregnancy complications following weight loss, a lower BMI improves outcomes,” said Dr. Trolice.

Future research should address the fertility outcomes of women who have been counseled by their providers to lose weight and the most effective method of counseling, noted Dr. O’Neill. “We have to find the best ways to address this at each fertility institution.”

The study had limited generalizability because of its narrow patient population and regional differences in access to insurance and weight loss specialists. COVID-19 also reduced the sample size, said Dr. O’Neill. She noted that patient perceptions might not equate with actual counseling delivered.

Physicians could be doing a better job of counseling patients with obesity and overweight on weight loss and fertility. A study of 48 women seeking infertility care at a large academic center found that less than half received advice on weight loss from their primary ob.gyn. prior to referral for infertility treatment.

Patients are thinking about this – many attempt to lose weight independently of support from their health care providers, said lead study author Margaret R. O’Neill, MD, a resident at the University of Massachusetts Medical Center in Worcester. Dr. O’Neill discussed these results at the American Society of Reproductive Medicine’s 2021 meeting.

Nearly half of all U.S. women of reproductive age have overweight or obesity, with a body mass index of >25 kg/m². Menstrual irregularity, ovulatory dysfunction, reduced fecundity, and lower efficacy of infertility treatment are some of the consequences of obesity on fertility, said Dr. O’Neill. Obesity also affects the health of expectant mothers and fetuses, increasing the likelihood of gestational diabetes, preterm delivery, and preeclampsia, and increased incidence of fetal anomalies.

“Unfortunately, even though the prevalence of obesity has been increasing substantially in our country, there’s not excellent rates of this being addressed by physicians,” said Dr. O’Neill. BMI is often left out of documentation and rates of referrals to weight loss specialists are also low.

Conversations have been taking place about IVF centers instituting different BMI cutoffs for certain types of assisted reproductive technology, she noted.

Dr. O’Neill and her colleagues undertook a survey to see what advice community providers were dispensing about weight management on fertility.
 

Infertility specialists offer the most guidance

The prospective study included 48 nonpregnant women of reproductive age women presenting for IVF who needed an anesthesia consultation because of elevated BMI (> 35) prior to initiation of IVF. Mean age was 36 years and mean BMI was 38.5. More than 70% of the patients were White and they were predominantly English speakers.

All participants had attempted weight loss, including an attempt in the last year, and 93.8% reported trying to lose weight in the last year. On average, patients weighed about 20 pounds less than their heaviest adult weight. Nineteen percent of the participants were at their heaviest adult weight.

While 60% said they’d received weight loss/infertility counseling by any health care provider, just 41.7% reported that their primary ob.gyn. counseled them about weight loss before referring them for treatment. Infertility specialists seem to provide the most assistance: Nearly 70% of the respondents said they’ve been counseled by these providers.

Women with a higher-than-average BMI (39) were more likely to report a referral to weight loss counseling compared with women not referred (37.9, P = .2). 

Investigators also asked patients about their knowledge of obesity and its relationship to other health conditions. About 90% understood that infertility and excess weight were related. Overall, they were less sure about the link between obesity and still birth, breast cancer, and birth defects. Only 37% were able to identify a normal BMI range.
 

Avoiding a touchy subject

BMI is a highly sensitive area for many women, despite its detrimental effect on fertility, Mark P. Trolice, MD, professor of obstetrics and gynecology at the University of Central Florida and director of the IVF Center in Orlando, said in an interview.

“By the time their journey has led them to an infertility specialist, most women are very anxious to begin treatment,” said Dr. Trolice, who was not involved in the survey. These patients, however, could interpret any medical advice to achieve a more optimal BMI and healthier lifestyle as a negative judgment that could delay their goal of having a healthy child, he said.

Physicians in turn may avoid these conversations because they don’t want to encourage the ire of patients and/or risk a negative online rating review, he added.

Don’t say ‘just lose weight’

When asked what type of counseling works best, many said that nonspecific recommendations such as “you need to lose weight” or “exercise more” were the least helpful. Targeted advice such as “avoid eating at night and take walks every day,” works more effectively. “Any kind of referral to a bariatrics team or weight loss program was seen as helpful by patients,” said Dr. O’Neill.

Suggestions that considered the difficulty of this process, such as seeking therapy, were also helpful. “Patients appreciated empathy, compassion, and encouragement” from their physicians, she said.
 

The role of physicians in weight loss

Physicians can make a difference. Studies show that patients who received weight loss counseling were more likely to attempt weight loss and report clinically significant weight loss.

The American College of Obstetricians and Gynecologists and ASRM recommend counseling patients with overweight and obesity to lose weight before getting pregnant. A modest weight loss of 10% is associated with improved ovulatory function and higher pregnancy rates, said Dr. O’Neill.

“Appropriately, the infertility specialist should strongly recommend [that women who are obese] obtain a more optimal BMI prior to fertility treatment. While there is no guarantee of decreased infertility and decreased pregnancy complications following weight loss, a lower BMI improves outcomes,” said Dr. Trolice.

Calculating the estimated glucose disposal rate (eGDR) as a proxy for the level of insulin resistance may be useful way to determine if someone with type 2 diabetes (T2D) is at risk for having a first stroke, Swedish researchers have found.

purestock/Thinkstock

In a large population-based study, the lower the eGDR score went, the higher the risk for having a first stroke became.

The eGDR score was also predictive of the chance of dying from any or a cardiovascular cause, Alexander Zabala, MD, reported at the annual meeting of the European Association for the Study of Diabetes (Abstract OP 01-4).

The link between insulin resistance and an increased risk for stroke has been known for some time, and not just in people with T2D. However, the current way of determining insulin resistance is not suitable for widespread practice.

“The goal standard technique for measuring insulin resistance is the euglycemic clamp method,” said Dr. Zabala, an internal medical resident at Södersjukhuset hospital and researcher at the Karolinska Institutet in Stockholm.

“For that reason, [the eGDR], a method based on readily available clinical factors – waist circumference, hypertension, and glycosylated hemoglobin was developed,” he explained. Body mass index can also be used in place of waist circumference, he qualified.

The eGDR has already been proven to be very precise in people with type 1 diabetes, said Dr. Zabala, and could be an “excellent tool to measure insulin resistance in a large patient population.”
 

Investigating the link between eGDR and first stroke risk

The aim of the study he presented was to see if changes in the eGDR were associated with changes in the risk of someone with T2D experiencing a first stroke, or dying from a cardiovascular or other cause.

An observational cohort was formed by first considering data on all adult patients with T2D who were logged in the Swedish National Diabetes Registry (NDR) during 2004-2016. Then anyone with a history of stroke, or with any missing data on the clinical variables needed to calculate the eGDR, were excluded.

This resulted in an overall population of 104,697 individuals, aged a mean of 63 years, who had developed T2D at around the age of 59 years. About 44% of the study population were women. The mean eGDR for the whole population was 5.6 mg/kg per min.

The study subjects were grouped according to four eGDR levels: 24,706 were in the lowest quartile of eGDR (less than 4 mg/kg per min), signifying the highest level of insulin resistance, and 18,762 were in the upper quartile of eGDR (greater than 8 mg/kg per min), signifying the lowest level of insulin resistance. The middle two groups had an eGDR between 4 and 6 mg/kg per min (40,187), and 6 and 8 mg/kg/min (21,042).

Data from the NDR were then combined with the Swedish Cause of Death register, the Swedish In-patient Care Diagnoses registry, and the Longitudinal Database for Health Insurance and Labour Market Studies (LISA) to determine the rates of stroke, ischemic stroke, hemorrhagic stroke, all-cause mortality, and cardiovascular mortality.
 

Increasing insulin resistance ups risk for stroke, death

After a median follow-up of 5.6 years, 4% (4,201) of the study population had had a stroke.

“We clearly see an increased occurrence of first-time stroke in the group with the lowest eGDR, indicating worst insulin resistance, in comparison with the group with the highest eGDR, indicating less insulin resistance,” Dr. Zabala reported.

After adjustment for potential confounding factors, including age at baseline, gender, diabetes duration, among other variables, the risk for stroke was lowest in those with a high eGDR value and highest for those with a low eGDR value.

Using individuals with the lowest eGDR (less than 4 mg/kg per min) and thus greatest risk of stroke as the reference, adjusted hazard ratios (aHR) for first-time stroke were: 0.60, 0.68, and 0.77 for those with an eGDR of greater than 8, 6-8, and 4-6 mg/kg per min, respectively.

The corresponding values for risk of ischemic stroke were 0.55, 0.68, and 0.75. Regarding hemorrhagic stroke, there was no statistically significant correlation between eGDR levels and stroke occurrence. This was due to the small number of cases recorded.

As for all-cause and cardiovascular mortality, a similar pattern was seen, with higher rates of death linked to increasing insulin resistance. Adjusted hazard ratios according to increasing insulin resistance (decreasing eGDR scores) for all-cause death were 0.68, 0.75, and 0.82 and for cardiovascular mortality were 0.65, 0.75, and 0.82.

A sensitivity analysis, using BMI instead of waist circumference to calculate the eGDR, showed a similar pattern, and “interestingly, a correlation between eGDR levels and risk of hemorrhagic stroke.” Dr. Zabala said.
 

Limitations and take-homes

Of course, this is an observational cohort study, so no conclusions on causality can be made and there are no data on the use of anti-diabetic treatments specifically. But there are strengths such as covering almost all adults with T2D in Sweden and a relatively long-follow-up time.

The findings suggest that “eGDR, which may reflect insulin resistance may be a useful risk marker for stroke and death in people with type 2 diabetes,” said Dr. Zabala.

“You had a very large cohort, and that certainly makes your results very valid,” observed Peter Novodvorsky, MUDr. (Hons), PhD, MRCP, a consultant diabetologist in Trenčín, Slovakia.

Dr. Novodvorsky, who chaired the session, picked up on the lack of information about how many people were taking newer diabetes drugs, such as the glucagon-like peptide 1 receptor antagonists and sodium glucose-lowering transport 2 inhibitors.

“As we all know, these might have protective effects which are not necessarily related to the glucose lowering or insulin resistance-lowering” effects, so could have influenced the results. In terms of how practical the eGDR is for clinical practice, Dr. Zabala observed in a press release: “eGDR could be used to help T2D patients better understand and manage their risk of stroke and death. 

“It could also be of importance in research. In this era of personalized medicine, better stratification of type 2 diabetes patients will help optimize clinical trials and further vital research into treatment, diagnosis, care and prevention.”

The research was a collaboration between the Karolinska Institutet, Gothenburg University and the Swedish National Diabetes Registry. Dr. Zabala and coauthors reported having no conflicts of interest.
