The American College of Physicians has issued new guidelines for managing acute major depressive disorder, suggesting those with moderate to severe depression may start with cognitive-behavioral therapy (CBT) alone or a second-generation antidepressant (SGA) alone.

The guidelines also state that patients with mild depression should start with CBT alone, and if a patient with moderate to severe depression prefers, they can use a combination of both CBT and an SGA.

These nuanced recommendations contrast sharply with the 2016 ACP guidelines for depression, which lumped all stages and severity levels together, and came with just one recommendation: Clinicians should choose between CBT and an SGA.

More data have come to light over the years, requiring the present update, reported lead author Amir Qaseem, MD, PhD, vice president of Clinical Policy and the Center for Evidence Reviews at the ACP, and adjunct faculty at Thomas Jefferson University, Philadelphia, and colleagues.

In addition to the focus on acute depression, Dr. Qaseem and colleagues highlighted the new guidelines' “consideration of patient values and preferences, and costs,” as well as responses to therapy.

Recommendations were derived from a network meta-analysis that included studies evaluating nonpharmacologic and pharmacologic therapies, the authors wrote in Annals of Internal Medicine. They compared effectiveness across a range of SGAs, “including selective serotonin reuptake inhibitors; serotonin-norepinephrine reuptake inhibitors; and others such as bupropion, mirtazapine, nefazodone, trazodone, vilazodone, and vortioxetine.”

This analysis yielded three pieces of clinical advice.

First, patients in the acute phase of mild depression should receive CBT alone as their initial treatment.

Dr. Qaseem and colleagues noted that many depression studies for pharmacologic therapies excluded these patients in favor of those with moderate to severe depression, leaving an evidence gap.

“Furthermore, the Clinical Guidelines Committee had concerns about adverse effects of SGAs in these patients and suggests that the use of SGAs as initial treatment of these patients should be based on additional considerations, such as limited access to or cost of CBT, history of moderate or severe major depressive disorder, or patient preferences,” they added.

The committee’s next recommendation, based on moderate-certainty evidence, suggested that CBT alone or an SGA alone should be considered for patients in the acute phase of moderate to severe depression. This call for monotherapy is balanced by a conditional recommendation based on low-certainty evidence that the same group may benefit from initial combination therapy with both CBT and an SGA.

“The informed decision on the options of monotherapy with CBT versus SGAs, or combination therapy, should be personalized and based on discussion of potential treatment benefits, harms, adverse effect profiles, cost, feasibility, patients’ specific symptoms (such as insomnia, hypersomnia, or fluctuation in appetite), comorbidities, concomitant medication use, and patient preferences,” the guidelines state.

The third and final recommendation offers an algorithm for patients who do not respond to initial therapy with an SGA. Multiple pathways are provided: Switch to CBT or augment with CBT; or switch to a different SGA or augment with a second pharmacologic therapy, such as mirtazapine, bupropion, or buspirone.

“These second-line treatment strategies show similar efficacy when compared with each other,” the guidelines committee noted.

Again, the guidelines suggest that second-line choices should be personalized based on the various factors previously discussed.

A timely update

“The new guideline is very different from the last guideline,” said Ryan Mire, MD, president of the ACP and practicing internal medicine physician in Nashville, Tenn. in a written comment. “ACP decided to update the depression guidelines with a focus on acute depression because approximately 70% of patients with major depressive disorder do not achieve remission and remain in the acute phase after the initial pharmacologic treatment attempt. In addition, there is new evidence on second-line treatments since the 2016 ACP guideline was published.”

Neil S. Skolnik, MD, of Thomas Jefferson University, Philadelphia, agreed that the guidelines offer a necessary and fresh perspective on caring for patients with depression.

“These guidelines are a helpful update, assuring us that we are using the latest, evidence-based therapies, and [they] are written in a practical, easy-to-implement manner,” Dr. Skolnik said in a written comment.

“First, the guidelines reaffirm that CBT is an effective first-line option, with or without the concurrent use of an SGA,” Dr. Skolnik said, noting that CBT alone may reduce likelihood of recurrence, compared with an SGA alone. “Many patients do not like the idea of medication, or the potential side effects of medications, and CBT is an evidenced-based approach that can be very helpful for patients.”

Dr. Skolnik also applauded the guidelines authors for offering a clear path forward for patients who do not have full remission after treatment – a common clinical scenario.

Valuable despite the gaps

Other experts expressed mixed impressions of the update, noting both highs and lows.

“Although [this guideline] has some gaps, it is more valuable in several ways than other widely consulted practice guidelines for depression,” wrote Miriam Shuchman, MD and Elia Abi-Jaoude, MSc, MD, PhD, of the University of Toronto, in an accompanying editorial.

Specifically, they praised the publication’s focus on shared decision-making in the treatment planning process.

“This effort to respond to patient preferences is crucial and may even increase the chance that patients will improve with treatment,” they wrote.

They also applauded the ACP’s efforts to recuse any committee members who may have had conflicts of interest “that could affect their judgment about treatments for depression.”

After highlighting these attributes, Dr. Shuchman and Dr. Abi-Jaoude noted that the guidelines still contain “significant gaps.”

Foremost, they pointed out the guidelines' emphasis on CBT to the exclusion of other nonpharmacologic options.

“The guideline does patients a disservice by leaving out several nonmedication treatment options that clinicians can offer as first- or second-line therapies,” they wrote.

This oversight may increase risk that patients simply hop from one SGA to another, which is a common, and often ineffective, strategy, according to Dr. Shuchman and Dr. Abi-Jaoude.

“Patients often go from one drug to the next in the hopes of landing on one that ‘works,’ ” the editorialists wrote. “This narrow clinical approach of pursuing medication-based treatments ignores the ways difficulties in a person’s work or relationships may contribute to their struggles with depression. At a time when the COVID-19 pandemic has underscored the importance of the social context of mental health, clinicians may need to consider other forms of support and tailor prescribing to what is most relevant and accessible for a particular patient.”

Dr. Shuchman and Dr. Abi-Jaoude went on to suggest several nonpharmacologic options beyond CBT, including interpersonal therapy, psychodynamic therapy, problem solving, behavioral activation, and guided self-help.

The other key gap they pointed out relates to withdrawal.

Although the guideline does advise physicians to taper antidepressants to reduce risk of withdrawal, the editorialists suggested that this recommendation lacked sufficient emphasis, as it can be a particularly difficult period in the treatment process.

“Tapering of an antidepressant may need to be done over months or years, not weeks, and a patient may need to visit a compounding pharmacy to obtain doses of a second-generation antidepressant not marketed by drug manufacturers so that prescriptions can be tapered even more slowly,” they suggested.

Financial costs remain unclear

Beyond the above medical considerations, one other piece of the depression puzzle remains unsolved: cost.

In a simultaneously published rapid review, Andreea Dobrescu, MD, PhD, of Cochrane Austria, and colleagues evaluated the relative cost-effectiveness of first- and second-step treatment strategies.

For most comparisons, evidence was insufficient to reach a conclusion, although they suggested that CBT may be more cost effective at the 5-year mark.

“For most pharmacologic and nonpharmacologic interventions for major depressive disorder, evidence was missing or was insufficient to draw conclusions about the cost-effectiveness of first- or second-step treatments for MDD,” Dr. Dobrescu and colleagues wrote. “The strongest evidence (albeit still low certainty of evidence) was for the cost-effectiveness of CBT compared with SGA as a first-step treatment over a 5-year time horizon from the societal and health care sector perspectives. However, this evidence should also be interpreted cautiously considering it is based on a single study.”

When asked about the financial findings, Dr. Mire agreed that more data are needed, especially because CBT and SGA costs range widely. He suggested that cost, for each patient, should be considered in the personalized approach now highlighted by the new guidelines.

The guidelines and the Cochrane cost-effectiveness study were supported by the ACP. The guidelines' authors and other individuals quoted in this article reported no conflicts of interest.

The U.S. Food and Drug Administration has approved bexagliflozin (Brenzavvy, TheracosBio) for the treatment of adults with type 2 diabetes.

The once-daily 20-mg oral sodium-glucose cotransporter 2 (SGLT2) inhibitor is indicated as an adjunct to diet and exercise to improve glycemic control for those with type 2 diabetes, but not type 1 diabetes. It can be used in adults with an estimated glomerular filtration rate (eGFR) > 30 mL/min per 1.73 m².

Approval was based on results from 23 clinical trials with more than 5,000 participants, including more than 300 patients with stage 3 kidney disease (eGFR < 60 and > 30 mL/min per 1.73 m²).

In the phase 3 studies, bexagliflozin significantly reduced hemoglobin A1c and fasting blood glucose at 24 weeks as monotherapy or as add-on to metformin and other glucose-lowering drugs and combinations. It also produced modest reductions in body weight and systolic blood pressure.

In the phase 3 Bexagliflozin Efficacy and Safety Trial (BEST) cardiovascular outcomes trial, the drug met its efficacy and safety objectives in patients at high cardiovascular risk. Noninferiority was demonstrated for the composite outcome of cardiovascular death, myocardial infarction, stroke, or unstable angina.

“As a class of drugs, SGLT2 inhibitors have shown tremendous benefit in treating adults with type 2 diabetes,” said Mason Freeman, MD, director of the Translational Research Center at Massachusetts General Hospital, Boston, in a press release from TheracosBio.

“Being involved in all of the clinical trials for Brenzavvy, I am greatly impressed with the efficacy of the drug in reducing blood glucose levels and I believe it is an important addition to the SGLT2 inhibitor class of drugs.”

As with other SGLT2 inhibitors, adverse events seen in the trials include ketoacidosis, lower limb amputation, volume depletion, urosepsis, pyelonephritis, Fournier’s gangrene, genital mycotic infections, and hypoglycemia when used with insulin or insulin secretagogues.

Bexagliflozin joins an already crowded field of SGLT2 inhibitors, some of which have been approved for additional cardiovascular and kidney indications.

Of interest, bexagliflozin was approved by the FDA for diabetes in cats in December 2022, as the first oral new animal drug to improve glycemic control in otherwise healthy cats with diabetes not previously treated with insulin.

Adding venetoclax to ibrutinib for chronic lymphocytic leukemia (CLL) improved rates of durable, treatment-free remission among 45 patients at the University of Texas MD Anderson Cancer Center, Houston.

Investigators led by Philip Thompson, MD, a hematologist/oncologist at the center, explained that CLL patients receiving ibrutinib, a Bruton’s kinase inhibitor, “rarely achieve complete remission with undetectable measurable residual disease,” so they stay on the costly treatment indefinitely or until disease progression or accumulating adverse events force a switch to venetoclax.

Using the two agents together, instead of consecutively, may allow strong responders to stop treatment altogether and suboptimal responders to have longer remissions, they said.

“We would not advocate prolonged Bruton’s kinase inhibitor use prior to starting venetoclax in treatment-naive patients, as the safety and efficacy of commencing venetoclax after a 3-month ibrutinib monotherapy phase has been repeatedly demonstrated,” the team said.

However, the investigators noted that their “study was not intended to directly answer the question of whether combination therapy is superior to the current paradigm of sequential monotherapy.” Randomized trials are looking into the matter. The study was published recently as a preprint on ResearchSquare.com and has not been peer reviewed.
 

Complete remission in over half

The 45 adult subjects had one or more high-risk features for CLL progression and had received at least 1 year of ibrutinib at 140-420 mg once daily, depending on tolerance. They had bone marrow detectable disease at study entry but did not meet criteria for progression. Median duration of ibrutinib at baseline was 32 months, and about half the subjects were on it as their initial therapy.

Venetoclax, a BCL2 inhibitor with a completely different mechanisms of action, was added to ibrutinib for up to 2 years, escalated up to a target dose of 400 mg once daily.

On intention-to-treat analysis, venetoclax add-on improved ibrutinib response to complete remission in 55% of patients; complete remission was defined as less than 1 CLL cell per 10,000 leukocytes in bone marrow on two consecutive occasions 6 months apart.

The rate of undetectable bone marrow disease was 57% after 1 year of combined treatment and 71% after venetoclax completion, at which point 23 patients with undetectable disease stopped ibrutinib along with venetoclax.

Five patients had disease progression at a median of 41 months after venetoclax initiation, one during combined therapy, three during ibrutinib maintenance afterward, and one with Richter transformation after complete remission and discontinuation of all treatment. No patient had died from CLL.

“There has so far been no significant difference noted in” time to residual disease re-emergence, the team said, based on whether or not patients continued ibrutinib after venetoclax add-on.

There was no significant difference in the rate of bone marrow clearance according to the presence or absence of TP53 abnormalities, complex karyotypes, or prior treatment status.

The most common grade 3/4 adverse event was neutropenia in 20% of patients. Nine patients developed nonmelanoma skin cancer during the trial; six were diagnosed with other solid tumors; three came down with grade 3 infections, and two developed myelodysplastic syndrome, both with a prior history of chemotherapy.

No one stopped venetoclax because of toxicity, but about a third of subjects required dose reductions, most often because of neutropenia.

The study was funded by AbbVie, which is commercializing venetoclax along with Genentech. Investigators disclosed ties to both companies and many others. Dr. Thompson disclosed ties to AbbVie, Pharmacyclics, Lilly, Adaptive Biotechnologies, Janssen, Beigene, and Genentech.

Adding venetoclax to ibrutinib for chronic lymphocytic leukemia (CLL) improved rates of durable, treatment-free remission among 45 patients at the University of Texas MD Anderson Cancer Center, Houston.

Investigators led by Philip Thompson, MD, a hematologist/oncologist at the center, explained that CLL patients receiving ibrutinib, a Bruton’s kinase inhibitor, “rarely achieve complete remission with undetectable measurable residual disease,” so they stay on the costly treatment indefinitely or until disease progression or accumulating adverse events force a switch to venetoclax.

Using the two agents together, instead of consecutively, may allow strong responders to stop treatment altogether and suboptimal responders to have longer remissions, they said.

“We would not advocate prolonged Bruton’s kinase inhibitor use prior to starting venetoclax in treatment-naive patients, as the safety and efficacy of commencing venetoclax after a 3-month ibrutinib monotherapy phase has been repeatedly demonstrated,” the team said.

However, the investigators noted that their “study was not intended to directly answer the question of whether combination therapy is superior to the current paradigm of sequential monotherapy.” Randomized trials are looking into the matter. The study was published recently as a preprint on ResearchSquare.com and has not been peer reviewed.
 

Complete remission in over half

The 45 adult subjects had one or more high-risk features for CLL progression and had received at least 1 year of ibrutinib at 140-420 mg once daily, depending on tolerance. They had bone marrow detectable disease at study entry but did not meet criteria for progression. Median duration of ibrutinib at baseline was 32 months, and about half the subjects were on it as their initial therapy.

Venetoclax, a BCL2 inhibitor with a completely different mechanisms of action, was added to ibrutinib for up to 2 years, escalated up to a target dose of 400 mg once daily.

Cancer dietitian Lisa Cianciotta often finds herself sitting across from a patient who suddenly fishes a bottle of antioxidant supplements from their bag and says, “My friend told me this works really well,” or “I read on the Internet that this is supposed to be really good for cancer.” 

Although taking an antioxidant pill sounds harmless, Ms. Cianciotta, a clinical dietitian who works with cancer patients at New York–Presbyterian Hospital, knows well that this popular dietary supplement can interfere with a patient’s radiation or chemotherapy.

But many patients with cancer believe these over-the-counter vitamins, minerals, or herbal remedies will help them, and most use at least one dietary supplement alongside their cancer treatment.

And that leaves Ms. Cianciotta with a delicate conversation ahead of her. 

Drug-supplement interactions are complex, often varying by supplement, cancer, and treatment type, and can do more harm than good. Popular dietary supplements may, for instance, cancel the effects of a cancer treatment, making it less effective, or increase serious side effects, such as liver toxicity. But in other cases, supplementation, such as vitamin D for patients who lack the vitamin, may be beneficial, Ms. Cianciotta said. 

These drug-supplement interactions can be hard to pinpoint, given that more than two-thirds of doctors don’t know their patients are using supplements.

Here’s what patients need to know about the potential risks of supplement use during treatment, and how oncologists can address this thorny, often poorly understood topic with patients.
 

The complex drug-supplement landscape

The list of dietary supplements and how they can interact with different treatments and cancer types is long and nuanced. 

But certain supplements appear to affect cancer treatments regardless of other things and should be avoided. Any supplement that strongly alters the body’s levels of the protein cytochromes P450 is one example. This group of enzymes plays a key role in metabolizing drugs, including chemotherapy and immunotherapy agents. 

Certain supplements – most notably St. John’s wort extract – may decrease or increase the activity of cytochrome P450, which can then  affect the concentrations of anticancer drugs in the blood, said William Figg, PharmD, an associate director of the Center for Cancer Research at the National Cancer Institute in Bethesda, Md. Studies show, for instance, that this common herbal supplement can increase the activity of cytochrome P450, resulting in lower levels of cancer drugs.

Outside of drug metabolism, patients with hormone-related cancers, such as breast and prostate cancers, should steer clear of dietary supplements that can alter levels of testosterone or estrogen, Dr. Figg said. The evergreen shrub ashwagandha, for example, is marketed to reduce stress and fatigue, but can also increase testosterone levels – a potential problem for those with prostate cancer receiving androgen deprivation therapy, which lowers testosterone levels. 

Many oncologists counsel patients against using antioxidant-based dietary supplements – particularly turmeric and green tea extract – while they have radiation therapy and certain chemotherapies. These therapies work by creating an abundance of highly reactive molecules called free radicals in tumor cells, which increase stress within these cells, ultimately killing them off. Antioxidants, in theory, can neutralize this effect, said Skyler Johnson, MD, a radiation oncologist at Huntsman Cancer Institute at the University of Utah, Salt Lake City.  Some studies suggest that antioxidant supplements may lessen the effects of radiation and chemotherapy, although the evidence is mixed.

Some dietary supplements, including high-dose green tea extract and vitamin A, can cause kidney or liver toxicity, and “many cancer patients already have compromised kidney or liver function,” said Jun J. Mao, MD, chief of integrative medicine at Memorial Sloan Kettering Cancer Center in New York. Even herbs that don’t interfere with how well a cancer drug works, such as stevia, can increase treatment-related side effects, such as nausea and vomiting. 

Another potential problem with dietary supplements: It’s nearly impossible to know exactly what’s in them. For instance, just last year, the Food and Drug Administration sent nearly 50 warning letters to companies marketing dietary supplements. The issue is that federal regulations governing production are less strict for supplements than for medications. As a result, some supplements contain ingredients not listed on the label. 

One historical example was the supplement PC-SPES, a mix of eight herbs, marketed to men with prostate cancer. The supplement was recalled in 2002 after certain batches were found to contain traces of prescription drugs, including diethylstilbestrol, ethinyl estradiol, warfarin, and alprazolam.

To further complicate matters, some dietary supplements can be helpful. Most patients with cancer “are malnourished and missing out on nutrients they could be getting from food,” said Ms. Cianciotta.

Patients are tested routinely for vitamin deficiencies and receive supplements as needed, she said. Vitamin D and folic acid are two of the most common deficiencies in this patient population. Vitamin D supplementation can improve outcomes in patients who have received a stem cell transplant by aiding engraftment and rebuilding the immune system, while folic acid supplementation can help to raise low red blood cell counts and hemoglobin levels. 

Although she rarely sees vitamin toxicity, Ms. Cianciotta stressed that more is not always better and supplement use, even when it seems safe or warranted due to a deficiency, should be taken under supervision, and monitored carefully by the patient’s care team. 
 

Bringing supplement use into the light

Too often, providers are unaware of a patient’s supplement use. 

A core reason: Dietary supplements are often touted as natural, which many patients equate with safety, said Samantha Heller, a senior clinical nutritionist at New York (N.Y.) University Langone Health. 

That means patients may not know a supplement can act like a drug and interfere with their cancer treatment, and thus may not see the importance of telling their doctors.

Still, the promise of herbs, vitamins, and minerals can be alluring, and there are many reasons patients decide to partake. One major appeal: Dietary supplements can help some patients feel empowered.

“Cancer is a disease that takes away a lot of control from the individual. Taking supplements or herbs is a way to regain some sense of control,” said Dr. Mao. 

The phenomenon can also be cultural, he said. Some people grow up taking herbs and supplements to stay healthy or combat health woes.

Pressure or advice from family or friends who may think they are helping a loved one with their dietary recommendations may play a role as well. Friends and family “cannot prescribe chemo, but they can buy herbs and supplements,” Dr. Mao said. 

Patients seeking greater control over their health or who feel high levels of anxiety may be more likely to take suggestions from friends and family or more likely to believe false or misleading claims about the efficacy or safety of supplements, explained  medical oncologist William Dahut, MD, chief scientific officer for the American Cancer Society. 

Plus, social media often amplifies and normalizes this misinformation, noted Dr. Johnson. In a 2021 study published in the Journal of the National Cancer Institute, he and colleagues found that one-third of the most popular articles on cancer treatment posted to social media in 2018 and 2019 contained false, inaccurate, or misleading information that was often harmful. 

Some of the false claims centered on unproven, potentially unsafe herbal remedies, according to Dr. Johnson. These included “lung cancer can be cured with cannabis oil” and “golden berries cure and prevent cancer.” 

Given exaggerated claims of “cures,” some patients may keep their supplement use under the radar out of fear they will be judged or criticized. 

“Clinicians should avoid making patients feel judged or telling people not to go online to do their own research,” Dr. Johnson said.

Guiding patients, instead, to accurate sources of online information may be one way to help patients feel empowered, he said. Cancer.gov and the Memorial Sloan Kettering Cancer Center’s About Herbs database provide accessible and accurate information on dietary supplements and cancer treatment for both health care professionals and patients, he noted. 

If a particular supplement is not safe during treatment, providers should be able to explain why, said  Ms. Cianciotta. In a recent study, 80% of health care providers surveyed believed that interactions between herbals and medications could be problematic, but only 15% could explain why. 

“Being able to explain why we are discouraging a particular supplement right now tends to be much better received than just telling a patient not to take something, because it is bad,” she said. 

Another key is listening closely to patients to understand why they may be taking a particular supplement. Does the patient feel out of control? Is nausea a problem? 

“Allowing patients to tell you why they are using a particular supplement will often reveal unmet needs or psychosocial challenges,” Dr. Mao said. This information can allow providers to suggest an evidence-based alternative, such as mindfulness meditation or acupuncture, to manage stress.

And if a patient has received a dietary supplement from well-meaning family and friends?

“Simply telling a patient that a given supplement is useless or harmful could create family tension,” said  Dr. Mao. 

Instead, he recommends reframing the issue. 

“We want to have a better understanding of how patients are tolerating chemo or immunotherapy before throwing other things on top of it. Let them know that now may just not be the right time to add a supplement to the mix,” Dr. Mao said. 

The bottom line: “Patients want to play an active role in their own care, and we want to help them do that in a safe way,” he said.

If a particular supplement is not safe during treatment, providers should be able to explain why, said  Ms. Cianciotta. In a recent study, 80% of health care providers surveyed believed that interactions between herbals and medications could be problematic, but only 15% could explain why. 

“Being able to explain why we are discouraging a particular supplement right now tends to be much better received than just telling a patient not to take something, because it is bad,” she said. 

Another key is listening closely to patients to understand why they may be taking a particular supplement. Does the patient feel out of control? Is nausea a problem? 

“Allowing patients to tell you why they are using a particular supplement will often reveal unmet needs or psychosocial challenges,” Dr. Mao said. This information can allow providers to suggest an evidence-based alternative, such as mindfulness meditation or acupuncture, to manage stress.

And if a patient has received a dietary supplement from well-meaning family and friends?

“Simply telling a patient that a given supplement is useless or harmful could create family tension,” said  Dr. Mao. 

Instead, he recommends reframing the issue. 

“We want to have a better understanding of how patients are tolerating chemo or immunotherapy before throwing other things on top of it. Let them know that now may just not be the right time to add a supplement to the mix,” Dr. Mao said. 

The bottom line: “Patients want to play an active role in their own care, and we want to help them do that in a safe way,” he said.

Doctors do not appear to be bouncing back from the pandemic’s early days – their happiness at and away from work continues to be significantly lower than before the pandemic. Physicians reported similar levels of unhappiness in 2022 too.

Fewer than half of physicians said they were currently somewhat or very happy at work, compared with 75% of physicians who said they were somewhat or very happy at work in a previous survey conducted before the pandemic, the new Medscape Physician Lifestyle & Happiness Report 2023 shows.*

“I am not surprised that we’re less happy now,” said Amaryllis Sánchez, MD, a board-certified family medicine physician and a certified physician coach.

“I speak to physicians around the country and I hear that their workplaces are understaffed, they’re overworked and they don’t feel safe. Although we’re in a different phase of the pandemic, doctors feel that the ground beneath them is still shaky,” said Dr. Sánchez, the author of “Recapturing Joy in Medicine.”

Most doctors are seeing more patients than they can handle and are expected to do that consistently. “When you no longer have the capacity to give of yourself, that becomes a nearly impossible task,” said Dr. Sánchez.

Also, physicians in understaffed workplaces often must take on additional work such as administrative or nursing duties, said Katie Cole, DO, a board-certified psychiatrist and a physician coach.

While health systems are aware that physicians need time to rest and recharge, staffing shortages prevent doctors from taking time off because they can’t find coverage, said Dr. Cole.

“While we know that it’s important for physicians to take vacations, more than one-third of doctors still take 2 weeks or less of vacation annually,” said Dr. Cole.

Physicians also tend to have less compassion for themselves and sacrifice self-care compared to other health care workers. “When a patient dies, nurses get together, debrief, and hug each other, whereas doctors have another patient to see. The culture of medicine doesn’t support self-compassion for physicians,” said Dr. Cole.

Physicians also felt less safe at work during the pandemic because of to shortages of personal protective equipment, said Dr. Sánchez. They have also witnessed or experienced an increase in abusive behavior, violence and threats of violence.

Physicians’ personal life suffers

Doctors maintain their mental health primarily by spending time with family members and friends, according to 2022’s Medscape Physician Lifestyle & Happiness Report. Yet half of doctors reported in a survey by the Physicians Foundation that they withdrew from family, friends or coworkers in 2022, said Dr. Sánchez.

“When you exceed your mental, emotional, and physical capacity at work, you have no reserve left for your personal life,” said Dr. Cole.

That may explain why only 58% of doctors reported feeling somewhat or very happy outside of work, compared with 84% who felt that way before the pandemic.

More women doctors said they deal with stronger feelings of conflict in trying to balance parenting responsibilities with a highly demanding job. Nearly one in two women physician-parents reported feeling very conflicted at work, compared with about one in four male physician-parents.

When physicians go home, they may be emotionally drained and tired mentally from making a lot of decisions at work, said Dr. Cole.

“As a woman, if you have children and a husband and you’re responsible for dinner, picking up the kids at daycare or helping them with homework, and making all these decisions when you get home, it’s overwhelming,” said Dr. Cole.
 

Prioritize your well-being

Doctors need to prioritize their own well-being, said Dr. Sánchez. “That’s not being selfish, that’s doing what’s necessary to stay well and be able to take care of patients. If doctors don’t take care of themselves, no one else will.”

Dr. Sánchez recommended that doctors regularly interact with relatives, friends, trusted colleagues, or clergy to help maintain their well-being, rather than waiting until a crisis to reach out.

A good coach, mentor, or counselor can help physicians gain enough self-awareness to handle their emotions and gain more clarity about what changes need to be made, she said.

Dr. Cole suggested that doctors figure out what makes them happy and fulfilled at work and try to spend more time on that activity. “Knowing what makes you happy and your strengths are foundational for creating a life you love.”

She urged doctors to “start thinking now about what you love about medicine and what is going right at home, and what areas you want to change. Then, start advocating for your needs.”

A combination of HER2-targeted drugs used in breast cancer is now available for use in colorectal cancer.

The U.S. Food and Drug Administration has granted accelerated approval to tucatinib (Tukysa) in combination with trastuzumab for use in RAS wild-type, HER2-positive unresectable or metastatic colorectal cancer that has progressed after fluoropyrimidine, oxaliplatin, and irinotecan-based chemotherapy.

This is the first FDA-approved treatment for HER2-positive metastatic colorectal cancer, maker Seagen said in a Jan. 19 press release.

“Historically, patients with HER2-positive metastatic colorectal cancer who have progressed following frontline therapy have had poor outcomes. The FDA approval of a chemotherapy-free combination regimen that specifically targets HER2 is great news for these patients,” John Strickler, MD, associate professor of medicine at Duke University Medical Center, Durham, N.C., said in the press release.

Dr. Strickler was the lead investigator on the approval trial, dubbed MOUNTAINEER, which involved 84 patients who met the treatment criteria and who had also been treated with an anti-VEGF antibody. Participants whose tumors were deficient in mismatch repair proteins or were microsatellite instability–high must also have received a PD-1 inhibitor. Patients who received prior anti-HER2 therapy were excluded, the FDA explained in its own press release.

Participants were treated with tucatinib 300 mg orally twice daily– the recommended dose in product labeling – with trastuzumab administered at a loading dose of 8 mg/kg intravenously on day 1 of cycle 1 followed by a maintenance dose of trastuzumab 6 mg/kg on day 1 of each subsequent 21-day cycle.

Overall response rate was 38%, and median duration of response was 12.4 months.

The most common adverse events, occurring in at least 20% of study participants, were diarrhea, fatigue, rash, nausea, abdominal pain, infusion related reactions, and pyrexia. The most common laboratory abnormalities were increased creatinine, decreased lymphocytes, increased alanine aminotransferase, and decreased hemoglobin, among others.

Serious adverse reactions occurred in 22% of patients. The most common (occurring in ≥ 2% of patients) were intestinal obstruction (7%); urinary tract infection (3.5%); and pneumonia, abdominal pain, and rectal perforation (2.3% each). Adverse reactions leading to permanent discontinuation occurred in 6% of patients, including increased alanine aminotransferase in 2.3%.

Continued approval for the indication may be contingent upon verification and description of clinical benefit in confirmatory trials, the company said.

A global, randomized phase 3 clinical trial (MOUNTAINEER-03) is ongoing and is comparing tucatinib in combination with trastuzumab and mFOLFOX6 with standard of care and is intended to serve as a confirmatory trial, the company said.

Tucatinib is already approved in combination with trastuzumab and capecitabine for use in the treatment of advanced unresectable or metastatic HER2-positive breast cancer.

Data from a dermatology monkeypox (mpox) registry reveal that patients struck during the 2022 worldwide outbreak experienced two nontraditional findings: Skin lesions that frequently appeared before systemic illness and a much lower overall numbers of lesions.

“Just these two findings alone show how important it is to remain clinically vigilant as dermatologists,” Esther Freeman, MD, PhD, director of global health dermatology at Massachusetts General Hospital, Boston, said in an interview. She is the corresponding author of the study, which analyzed 101 mpox cases from 13 countries and was published online on in the Journal of the American Academy of Dermatology.

NIAID

“Mpox appeared to manifest differently than in previous outbreaks with morphologic and clinical evolutions much different than previously reported in endemic and prior outbreaks,” added Dr. Freeman. “Dermatologists should continue to keep mpox on the differential as it continues to circulate at low levels in the population and is a mimicker of many other common skin diseases.”

According to the Centers for Disease Control and Prevention, as of Jan. 20, 2023, there have been 30,061 cases of mpox in the United States during the outbreak that began in 2022; 23 people died. Worldwide, the number of cases neared 85,000.

In contrast to past outbreaks where patients may have had dozens or hundreds of lesions, 20% had only 1 lesion, while 52% had 2-5 lesions, and 20% had 6-20 lesions. “There may be only a few lesions, so index of suspicion needs to be high,” Dr. Freeman said.

According to the study, “the most common skin lesion morphologies and secondary characteristics reported included papules, vesicles/blisters, pustules, erosions/ulcers and crust/scabs.” Dr. Freeman cautioned that “lesions may not go through the ‘typical’ progression from papule to pustule. The initial lesion could even be an ulceration or a crust. For dermatologists, this means you need to have a high index of suspicion, especially if you see a new onset lesion in the groin or perianal area, though they can also start elsewhere.”

She added that “the lesion you see on exam could be a classic pustule/pseudopustule, but it might not be – it could be a small perianal erosion or ulceration. If you have any concern it could be mpox, it’s a good idea to test by PCR.”

 

Morbilliform rash, scarring reported

The study also highlighted 10 cases of morbilliform rash. “A morbilliform exanthem is pretty nonspecific, and usually cases of mpox have more specific features,” dermatologist and study coauthor Misha Rosenbach, MD, of the University of Pennsylvania, Philadelphia, said in an interview.

“Given the current low rates of mpox, I do not think most dermatologists need to worry about mpox when evaluating morbilliform exanthems. However, in high-risk patients or patients with other morphologies, it is worth noting that there’s a chance that this may be related.”

Emory University dermatologist Howa Yeung, MD, MSc, who wasn’t involved with the study, said in an interview that morbilliform rashes in the mouth/tongue area, mostly on days 1-5, should be considered a possible sign of mpox. “While I didn’t typically think of monkeypox virus as a cause of viral exanthems, I will now add it to my differential diagnoses.”

Ketamine poisonings in the United States increased 81% between 2019 and 2021, according to a new analysis of calls to poison control centers.

Although the overall ketamine exposures were low, researchers say the findings add to a growing body of research that suggests recreational ketamine use may be on the rise.

“Ketamine is by no means the most dangerous drug, but it could be dangerous if combined with drugs such as alcohol or if used in potentially hazardous situations – physically hazardous or socially hazardous,” lead author Joseph Palamar, PhD, associate professor and epidemiologist at New York University Langone Health, New York, told this news organization.

“People who decide to use ketamine recreationally need to be educated about potential risks,” Dr. Palamar said.

The findings were recently published online in the Journal of Psychopharmacology.
 

More widespread use

Researchers noted that ketamine use has become more widespread in the United States due in part to increasing availability of ketamine in both clinical and nonclinical settings.

Previous work by Dr. Palamar documented an increase in recreational use of ketamine at dance clubs and an increase in ketamine seizures by the Drug Enforcement Administration.

In the current study, investigators analyzed data from the National Poison Control database and included cases reported by 51 of the 55 poison control centers in the United States.

They identified 758 cases involving ketamine exposure between the first quarter of 2019 and the last quarter of 2021 in individuals aged 13 and older, more than half of whom were men.

The number of ketamine exposures increased 81.1% during the study period, rising from 37 to 67 (P = .018).

Nearly 40% of callers reported intentional misuse or abuse of ketamine, while 19.7% involved a suspected suicide or suicide attempt. The ketamine exposure was unintended in 18.9% of cases, and 10.6% of calls involved an adverse drug reaction.

Onep-third of cases involved co-use of other substances, most commonly benzodiazepines, opioids, or alcohol.

The route of administration was ingestion for 44.3%, injection for 18.8%, and inhalation for 17.6%. Another 19.3% involved another route or a combination of routes.

Nearly 20% of cases reported a major adverse effect or death, 42.8% reported a moderate effect, 25.8% a minor effect, and 11.8% no effect. There were seven deaths reported in ketamine-related calls, although Dr. Palamar noted it is unlikely those deaths were due solely to ketamine use.

Researchers didn’t analyze specific harms reported in the calls, but chronic and heavy ketamine use has been previously associated with cognitive impairment, urinary cystitis and other urinary tract issues, and upper gastrointestinal problems.

In addition, using ketamine with gamma-hydroxybutyrate (GHB) or opioids was associated with a significantly higher risk for major adverse effects (P < .001 for both). Injecting ketamine was also linked to a higher prevalence of major adverse effects, although the association did not quite reach significance (P < .05).
 

Cause for concern

Commenting on the findings, Timothy Wiegand, MD, director of Addiction Toxicology and Toxicology Consult Service and associate professor of emergency medicine at the University of Rochester Medical Center and Strong Memorial Hospital, New York, noted the data on co-use of ketamine with other drugs were cause for concern.

“I think the co-occurring behaviors are critical here with concomitant use of opioids and GHB, intravenous drug use, or that it is used in an attempt to harm one’s self because it allows for identification of these behaviors or use patterns,” said Dr. Wiegand, who was not involved with the research.

He added that it is important for “addiction providers and others in medicine or in the addiction field to be aware of trends” associated with ketamine.

“At the same time, a focus on general prevention, and access to care and treatment, and understanding how to implement harm reduction strategies remain high priorities,” Dr. Wiegand said.

The study was funded by the National Institute on Drug Abuse. Dr. Palamar has reported consulting for Alkermes. Dr. Wiegand has reported no relevant financial relationships.
