E-cigarettes may be synonymous with vaping to most physicians, but there are other ways for patients to inhale nicotine or tetrahydrocannabinol-containing aerosols, according to investigators at the Cleveland Clinic.

Devices such as water pipes and techniques like dipping and dabbing “are increasingly popular, and use may not be recognized through a traditional substance use history,” Humberto Choi, MD, and associates wrote in the Annals of the American Thoracic Society.

These “alternate aerosol inhalation methods” have been poorly described thus far, so little is known about their scope of use and potential health impact, they noted.

Dripping involves an e-cigarette modified to expose the heating coil. The e-cigarette liquid is dripped directly onto the hot coil, which produces immediate aerosolization and results in a thicker cloud.

Dripping “may expose users to higher levels of nicotine compared to e-cigarette inhalation” and lead to “increased release of volatile aldehydes as a result of the higher heating potential of direct atomizer exposure,” the investigators suggested.

Water pipes, or bongs, produce both smoke and vapor, although an electronic vaporizer can be attached to create a “vape bong.” About 21% of daily cannabis users report using a bong, but tobacco inhalation is less common. Cases of severe pulmonary infections have been associated with bong use, along with a couple of tuberculosis clusters, Dr. Choi and associates said.

Dabbing uses butane-extracted, concentrated cannabis oil inhaled through a modified water pipe or bong or a smaller device called a “dab pen.” A small amount, or “dab,” of the product is placed on the “nail,” which replaces the bowl of the water pipe, heated with a blowtorch, and inhaled through the pipe, the researchers explained.

The prevalence of dabbing is unknown, but “the most recent Monitoring the Future survey of high school seniors shows that 11.9% of students have used a marijuana vaporizer at some point in their life,” they said.

Besides the fire risks involved in creating the material needed for dabbing – use of heating plates, ovens, and devices for removing butane vapors – inhalation of residual butane vapors could lead to vomiting, cardiac arrhythmias, acute encephalopathy, and respiratory depression, Dr. Choi and associates said.

Nicotine dependence is also a concern, as is the possibility of withdrawal symptoms. “Patients presenting with prolonged and severe vomiting, psychotic symptoms, or other acute neuropsychiatric symptoms should raise the suspicion of [tetrahydrocannabinol]-containing products especially synthetic cannabinoids,” they wrote.

Data, as we all know, have taken over the world. Only what is “data-driven” counts. Doctors, teachers, policemen, all learn to “juke the stats.”

Statistical objectivity is in, individuality is out. You may have taught for 30 years and gained a sense for which child has a problem that needs intervention and which one just needs patience and time to develop. You may have managed patients for decades and have a hunch about who needs immediate help and who can be watched. But “senses” and “hunches” can’t be measured and therefore do not exist, or better, don’t count. Numbers count!

Data-obsession reflects what Germans call the Zeitgeist, the spirit of the age. But the Germans will have to come up with a different word for our age, won’t they? Nobody can measure a “spirit.”

Still, you know the spirit’s there, when it knocks you over and stomps on you.

The one sphere of life that has resisted being reduced to numbers is sports. In sports, you don’t need complex analysis to know who’s No. 1 and who’s number everything else. No. 1 crosses the finish line first, wins the most games, knocks out the opponent. The one lying on the mat is No. 2.

Of course, sports always had lots of numbers. Baseball fans have always known about batting averages, runs batted in, earned run averages. But there were always those individual intangibles that goggle the eyes of small boys and keep sportswriters in business: this athlete’s “ferocious drive,” that one’s “will to win,” the way a third “always comes through in the clutch.” Pitchers who couldn’t throw fast anymore were “crafty.” Grizzled, tobacco-chewing scouts could sense which youngster “looked like a ballplayer.”

As if you didn’t already know, you can tell how old I am to talk this way. Bill James and his statistical acolytes put paid to that old kind of thinking a long time ago. Read Moneyball or see the movie. In sports too, it’s now all about the stats.

To generate flagging interest among the young for America’s now-stodgy pastime, Major League Baseball has brought out Statcast 2.0., which adds, according to a recent news story, “Doppler-based tracking of pitch velocity, exit velocity, launch angles, and spin rates, and defensive tracking of players.” Multicamera arrays produce “biomechanical imaging and skeletal models that can help pitchers with delivery issues or batters with swing path quandaries.”

And so we have lots of new data to ponder: exit velocity – how fast a hit ball leaves the bat; launch angle – what angle it leaves at; spin rate – how fast a thrown curveball spins; and defensive tracking – how many feet this shortstop can move left to snag a ground ball, or a right-fielder to catch a fly. And there are new, composite stats, like OPS (on-base plus slugging). I will not try to explain OPS, because it is a mathematical abstraction that I cannot grasp. It signifies a blend of on-base percentage and slugging percentage, which to me is like what you get when you blend a tomato with a broccoli. Or something.

And, stats aside, you do still have to win. Not long ago the Boston Red Sox had a relief pitcher whose spin rate was splendid, but he couldn’t get anybody out.

The real aim of the new broadcast innovations noted above comes at the end of the report:

In an effort to at least reach, if not grow, a younger fan base, MLB from now on will focus on video engagement, gaming, and augmented reality on Snapchat.

You got it: the goal is to reduce baseball to a video game, and its players to gaming characters, perhaps with big contracts and marketing deals. Hey, check out that dude’s OPS!

You can’t measure a Zeitgeist, but you certainly know when it’s sitting on your chest. Your respirations get depressed. Measurably.

Yeah, I sound like every cranky old man in history. But hey – I’m Emeritus! See this column’s title!

In addition, the article has one more detail:

Curiosity about whether a fly ball to deep right field at Fenway Park would be a home run at Yankee Stadium can be satisfied by overlaying the Yankee Stadium footprint on top of Fenway.

Maybe it would satisfy you, buddy, but anything that superimposes Yankee Stadium on top of Fenway Park dissatisfies me by a factor of 6.7!

THE CASE

An obese 90-year-old White man presented for a 1-month follow-up with his family physician after being hospitalized for an acute exacerbation of heart failure (HF). In addition to New York Heart Association (NYHA) Class III heart failure with reduced ejection fraction (HFrEF), he had a history of tobacco abuse, hyperlipidemia, atrial fibrillation, coronary artery disease, stage 3 chronic kidney disease, and benign prostatic hyperplasia. The patient’s family accompanied him during the visit to discuss hospice care.

The patient complained of persistent shortness of breath that limited his activities of daily living (ADLs) and lower extremity and scrotal edema. He denied chest pain, orthopnea, paroxysmal nocturnal dyspnea, ascites, nocturia, and nocturnal cough.

The patient had undergone a coronary artery bypass graft 23 years earlier. His HF was being managed with metoprolol tartrate 25 mg bid, spironolactone 25 mg/d, and furosemide 80 mg/d.

Examination revealed bilateral 3+ pitting edema in the lower extremities midway up the shin, crackles to the inferior scapula bilaterally, and a 3/6 systolic murmur with regular rate and rhythm. The remainder of the physical exam was normal. The patient’s vitals were within normal limits, with an oxygen saturation of 90%.

The patient’s most recent chest x-ray demonstrated mild cardiomegaly. An echocardiogram showed an ejection fraction of 44% with severe bi-atrial enlargement, moderate-to-severe mitral regurgitation, and mild-to-moderate aortic insufficiency. His brain natriuretic peptide (BNP) was 915 pg/mL (normal range for patients ages 75-99 years, < 450 pg/mL).

THE DIAGNOSIS

The differential diagnosis for the patient’s shortness of breath included chronic obstructive pulmonary disease secondary to his smoking history, pulmonary embolus, respiratory infection, anemia, and medication-related adverse effects. The patient’s history of renal disease merited consideration of a nephrotic syndrome causing low albumin, which could explain his edema. Another possible cause of the edema was venous insufficiency. However, given the patient’s extensive cardiac history, the most likely explanation for his shortness of breath and edema was congestive HF that was unresponsive to the current diuretic regimen.

Several changes to the patient’s medications were made. Lisinopril 2.5 mg/d was started due to the mortality benefit of angiotensin-converting enzyme inhibitors in the treatment of HFrEF.¹ Metoprolol tartrate 25 mg/d was transitioned to metoprolol succinate 50 mg/d, as only the longer-acting succinate version has shown mortality benefit in HFrEF.¹ (Other beta-blockers with mortality benefit include carvedilol and bisoprolol.¹) The furosemide 80 mg/d was replaced with torsemide 100 mg/d to provide an enhanced diuretic effect for symptomatic relief. The spironolactone dose was not increased due to concerns about the patient’s renal function. Of note, spironolactone was included in the patient’s regimen based on his NYHA classification, as well as the potential mortality benefits and improvement in edema seen in HFrEF patients.¹ Spironolactone can be used with loop and/or thiazide diuretics in the treatment of HF.

Continue to: Within 5 days...

Within 5 days, the patient had lost 6 lb and his oxygen saturation had improved from 90% to 95%. He reported improvements in his breathing and was able to move around more easily.

DISCUSSION

There are several possible explanations for torsemide’s superior diuretic effect in this patient. Unlike furosemide, torsemide absorption is not influenced by intestinal edema, which is commonly seen in patients with HF. It has a longer half-life and improved bioavailability that is not altered by food intake. Torsemide also inhibits the actions of aldosterone through its interaction with the renin-angiotensin-aldosterone system and aldosterone receptor, leading to further diuresis and reduced cardiac remodeling.²

What the evidence shows. The ­TORIC trial was an open-label, nonrandomized, post-marketing surveillance study of 1377 patients with NYHA Class II–III HF who received diuretic therapy with torsemide 10 mg/d, furosemide 40 mg/d, or another diuretic for 12 months.³ Significantly lower total mortality and cardiac mortality was found in the torsemide group; in addition, a significantly greater proportion of patients in the torsemide group showed improvement in NYHA classification.³ Murray et al reported a reduction in hospitalization rates with torsemide therapy vs furosemide therapy in a randomized trial of 234 HF patients (32% vs 17%, P = 0.01).⁴ The ASCEND-HF trial, a large international acute HF trial comparing torsemide with furosemide, demonstrated a nonsignificant reduction in 30-day and 180-day events (all-cause mortality or HF hospitalization) in those receiving torsemide, after risk adjustment.⁵ Torsemide has also been shown to improve quality of life compared to furosemide.⁶

Given the patient’s extensive cardiac history, the most likely explanation for his shortness of breath and edema was congestive HF that was unresponsive to his diuretic regimen.

Preliminary results from the TORNADO trial,⁷ a multicenter randomized controlled trial, demonstrated superior symptom improvement in HF patients taking torsemide compared to those taking furosemide.⁸ The preliminary endpoint—a composite of improvement in NYHA class, improvement in distance of at least 50 m during a 6-minute walk test, and a decrease in fluid retention of at least 0.5 ohms at 3-month follow-up—was achieved by 94% and 58% of patients on torsemide and furosemide, respectively (P = 0.03).⁸ A total of 7 patients (3 in the torsemide and 4 in the furosemide group) were hospitalized for worsening HF during the follow-up period.⁸

A 2020 meta-analysis of more than 19,000 patients compared furosemide to torsemide and found a number needed to treat (NNT) of 23 to prevent a hospitalization due to HF; an NNT of 5 for improvement in NYHA functional status; and an NNT of 40 for reduction in cardiac mortality.⁹

Continue to: Our patient

Our patient reported feeling “great” at the 6-week follow-up appointment, with significant improvement in breathing and ability to perform his ADLs. His NYHA classification improved to Class II. He had lost 26 pounds (back to his weight 9 months prior), and his oxygen saturation was 97%.

On exam, the bilateral peripheral edema in his lower extremities had improved from 3+ to 1+, with the edema extending just distal to the mid-shin. Only mild crackles were present at the lung bases. The remainder of his physical examination was unchanged. His vital signs were within normal limits with no signs of hypotension. A basic metabolic panel was obtained to confirm his electrolytes were still within normal limits. His BNP had decreased to 230 pg/mL.

The patient declined the referral for hospice evaluation due to the significant improvement in his symptoms.

THE TAKEAWAY

A significant clinical improvement and improved quality of life were achieved with the transition from furosemide to torsemide. It is apparent that the patient’s furosemide had an inferior diuretic effect compared to torsemide, whether that be secondary to his dose or due to the unpredictable nature of furosemide’s bioavailability, especially in the setting of intestinal edema.

A growing body of literature^9-11 suggests torsemide’s superiority over furosemide with no signs of increased adverse effects. Although additional prospective, head-to-head trials are needed, at this point in time it is appropriate to consider the use of torsemide in a patient with HF who does not seem to be fully responding to furosemide.

Preliminary results from the TORNADO trial,⁷ a multicenter randomized controlled trial, demonstrated superior symptom improvement in HF patients taking torsemide compared to those taking furosemide.⁸ The preliminary endpoint—a composite of improvement in NYHA class, improvement in distance of at least 50 m during a 6-minute walk test, and a decrease in fluid retention of at least 0.5 ohms at 3-month follow-up—was achieved by 94% and 58% of patients on torsemide and furosemide, respectively (P = 0.03).⁸ A total of 7 patients (3 in the torsemide and 4 in the furosemide group) were hospitalized for worsening HF during the follow-up period.⁸

A 2020 meta-analysis of more than 19,000 patients compared furosemide to torsemide and found a number needed to treat (NNT) of 23 to prevent a hospitalization due to HF; an NNT of 5 for improvement in NYHA functional status; and an NNT of 40 for reduction in cardiac mortality.⁹

Continue to: Our patient

Our patient reported feeling “great” at the 6-week follow-up appointment, with significant improvement in breathing and ability to perform his ADLs. His NYHA classification improved to Class II. He had lost 26 pounds (back to his weight 9 months prior), and his oxygen saturation was 97%.

On exam, the bilateral peripheral edema in his lower extremities had improved from 3+ to 1+, with the edema extending just distal to the mid-shin. Only mild crackles were present at the lung bases. The remainder of his physical examination was unchanged. His vital signs were within normal limits with no signs of hypotension. A basic metabolic panel was obtained to confirm his electrolytes were still within normal limits. His BNP had decreased to 230 pg/mL.

The patient declined the referral for hospice evaluation due to the significant improvement in his symptoms.

THE TAKEAWAY

A significant clinical improvement and improved quality of life were achieved with the transition from furosemide to torsemide. It is apparent that the patient’s furosemide had an inferior diuretic effect compared to torsemide, whether that be secondary to his dose or due to the unpredictable nature of furosemide’s bioavailability, especially in the setting of intestinal edema.

A growing body of literature^9-11 suggests torsemide’s superiority over furosemide with no signs of increased adverse effects. Although additional prospective, head-to-head trials are needed, at this point in time it is appropriate to consider the use of torsemide in a patient with HF who does not seem to be fully responding to furosemide.

THE CASE

An obese 90-year-old White man presented for a 1-month follow-up with his family physician after being hospitalized for an acute exacerbation of heart failure (HF). In addition to New York Heart Association (NYHA) Class III heart failure with reduced ejection fraction (HFrEF), he had a history of tobacco abuse, hyperlipidemia, atrial fibrillation, coronary artery disease, stage 3 chronic kidney disease, and benign prostatic hyperplasia. The patient’s family accompanied him during the visit to discuss hospice care.

The patient complained of persistent shortness of breath that limited his activities of daily living (ADLs) and lower extremity and scrotal edema. He denied chest pain, orthopnea, paroxysmal nocturnal dyspnea, ascites, nocturia, and nocturnal cough.

The patient had undergone a coronary artery bypass graft 23 years earlier. His HF was being managed with metoprolol tartrate 25 mg bid, spironolactone 25 mg/d, and furosemide 80 mg/d.

Examination revealed bilateral 3+ pitting edema in the lower extremities midway up the shin, crackles to the inferior scapula bilaterally, and a 3/6 systolic murmur with regular rate and rhythm. The remainder of the physical exam was normal. The patient’s vitals were within normal limits, with an oxygen saturation of 90%.

The patient’s most recent chest x-ray demonstrated mild cardiomegaly. An echocardiogram showed an ejection fraction of 44% with severe bi-atrial enlargement, moderate-to-severe mitral regurgitation, and mild-to-moderate aortic insufficiency. His brain natriuretic peptide (BNP) was 915 pg/mL (normal range for patients ages 75-99 years, < 450 pg/mL).

THE DIAGNOSIS

The differential diagnosis for the patient’s shortness of breath included chronic obstructive pulmonary disease secondary to his smoking history, pulmonary embolus, respiratory infection, anemia, and medication-related adverse effects. The patient’s history of renal disease merited consideration of a nephrotic syndrome causing low albumin, which could explain his edema. Another possible cause of the edema was venous insufficiency. However, given the patient’s extensive cardiac history, the most likely explanation for his shortness of breath and edema was congestive HF that was unresponsive to the current diuretic regimen.

Several changes to the patient’s medications were made. Lisinopril 2.5 mg/d was started due to the mortality benefit of angiotensin-converting enzyme inhibitors in the treatment of HFrEF.¹ Metoprolol tartrate 25 mg/d was transitioned to metoprolol succinate 50 mg/d, as only the longer-acting succinate version has shown mortality benefit in HFrEF.¹ (Other beta-blockers with mortality benefit include carvedilol and bisoprolol.¹) The furosemide 80 mg/d was replaced with torsemide 100 mg/d to provide an enhanced diuretic effect for symptomatic relief. The spironolactone dose was not increased due to concerns about the patient’s renal function. Of note, spironolactone was included in the patient’s regimen based on his NYHA classification, as well as the potential mortality benefits and improvement in edema seen in HFrEF patients.¹ Spironolactone can be used with loop and/or thiazide diuretics in the treatment of HF.

Within 5 days, the patient had lost 6 lb and his oxygen saturation had improved from 90% to 95%. He reported improvements in his breathing and was able to move around more easily.

DISCUSSION

There are several possible explanations for torsemide’s superior diuretic effect in this patient. Unlike furosemide, torsemide absorption is not influenced by intestinal edema, which is commonly seen in patients with HF. It has a longer half-life and improved bioavailability that is not altered by food intake. Torsemide also inhibits the actions of aldosterone through its interaction with the renin-angiotensin-aldosterone system and aldosterone receptor, leading to further diuresis and reduced cardiac remodeling.²

What the evidence shows. The ­TORIC trial was an open-label, nonrandomized, post-marketing surveillance study of 1377 patients with NYHA Class II–III HF who received diuretic therapy with torsemide 10 mg/d, furosemide 40 mg/d, or another diuretic for 12 months.³ Significantly lower total mortality and cardiac mortality was found in the torsemide group; in addition, a significantly greater proportion of patients in the torsemide group showed improvement in NYHA classification.³ Murray et al reported a reduction in hospitalization rates with torsemide therapy vs furosemide therapy in a randomized trial of 234 HF patients (32% vs 17%, P = 0.01).⁴ The ASCEND-HF trial, a large international acute HF trial comparing torsemide with furosemide, demonstrated a nonsignificant reduction in 30-day and 180-day events (all-cause mortality or HF hospitalization) in those receiving torsemide, after risk adjustment.⁵ Torsemide has also been shown to improve quality of life compared to furosemide.⁶

The miniscule papules arising suddenly on the trunk and genitals with linear arrays and clusters are clinically consistent with lichen nitidus, an uncommon eruption without a clear etiology.

Presentations may be focal or widespread and range from mildly itchy to asymptomatic. Children and young adults are most often affected. Linear arrays may appear in response to the trauma of scratching, which is termed the Koebner phenomenon. The differential diagnosis includes molluscum contagiosum, lichen planus, and lichen spinulosis. Usually these conditions can be distinguished clinically, but a biopsy would differentiate them, if needed. It’s worth noting, too, that lichen nitidus papules are monomorphic and lack the umbilication that is seen with molluscum contagiosum.

Cases of lichen nitidus clear up spontaneously, although usually months to years after diagnosis. Lichen nitidus is not contagious. Reassurance is, however, important as many patients may have experienced misdiagnosis and have concerns about sexual transmission because of the location of the papules on their genitals.

Treatment is often unnecessary. However, if itching is problematic, topical steroids and other topical antipruritics may be used. Topical hydrocortisone 2.5% cream or ointment for skin folds and genitals may be safely used, as well as topical triamcinolone 0.1% for the trunk and extremities. Pramoxine lotion (Sarna) is an over-the-counter nonsteroidal antipruritic. Oral nonsedating antihistamines can also be used as an adjunct.

This patient was reassured that the lesions were not contagious. Due to the itching, he was started on the pramoxine lotion twice daily, as needed, and the lesions cleared in about 6 months.

Home administration of bortezomib (Velcade), as a once or twice-weekly subcutaneous self-injection is safe in patients with myeloma, significantly reducing hospital visits, and likely improving quality of life, a study shows.

The majority (43 of 52 patients) successfully self-administered bortezomib and completed the course. Also, hospital visits for those on the so-called Homecare programme reduced by 50%, with most visits comprising a fortnightly drug pickup from the drive-through pharmacy.

The work was presented as a poster by lead author and researcher, Kanchana De Abrew, hematology consultant at University Hospital Southampton NHS Foundation Trust, at this year’s virtual British Society of Haematology (BSH) meeting. De Abrew conducted the study while at Queen Alexandra Hospital, Portsmouth.

“We wanted to minimize patient visits to hospital because with travel time and waiting time, patients can easily find a visit takes up a whole morning, so this relates to their quality of life as well as having financial implications for patients,” Dr. De Abrew said in an interview. It also reduced the impact on day units and improved capacity for other services.

Dr. De Abrew noted that the study was conducted in the pre-COVID-19 era, but that the current enhanced threat of infection only served to reinforce the benefits of self-administration at home and avoiding unnecessary hospital visits.

“This project could easily be set up in other hospitals and some other centers have already contacted us about this. It might suit rural areas,” she added.
 

‘Safe and effective’

Dr. Matthew Jenner, consultant hematologist for University Hospital Southampton NHS Foundation Trust, who was not involved in the study, remarked that the study demonstrated another way to deliver bortezomib outside of hospital in addition to home care services that require trained nurses to administer treatment. “With a modest amount of training of the patient and family, it is both a safe and effective way of delivering treatment. This reduces hospital visits for the patient and frees up much needed capacity for heavily stretched chemotherapy units, creating space for other newer treatments that require hospital attendance.

“It is of benefit all round to both the patients undertaking self-administration and those who benefit from improved capacity,” added Dr. Jenner.
 

Avoiding hospital visits

Myeloma patients are already immunosuppressed prior to treatment and then this worsens once on treatment. Once they are sitting in a clinic environment they are surrounded by similarly immunosuppressed patients, so their risk is heightened further.

Figures suggest myeloma cases are on the increase. Annually, the United Kingdom sees around 5,800 new cases of myeloma and incidence increased by a significant 32% between the periods of 1993-1995 and 2015-2017. These figures were reflected in the patient numbers at the Queen Alexandra Hospital where the study was carried out. Many patients receive bortezomib, which forms the backbone of four National Institute for Health and Care Excellence (NICE) approved regimens.

“Patients are living longer so in the early 2000s patients had a life expectancy of 2-3 years, whereas now patients live for around 5 years. Also, the scope and lines of treatments have increased a lot. Over 50% of patients are likely to have bortezomib at some point in their management,” explained Dr. De Abrew.

Bortezomib is given once or twice weekly as a subcutaneous injection, and this usually continues for approximately 6-8 months with four to six cycles. Administering the drug in hospital requires around a half-hour slot placing considerable burden on the hematology day unit resources, and this can adversely affect the patient experience with waiting times and the need for frequent hospital visits.
 

Patient or relatives taught to self-administer at home

In 2017, clinical nurse specialists taught suitable patients to self-administer bortezomib in the Homecare protocol. Patients collected a 2-week supply of the drug. The protocol aimed to improve patient quality of life by reducing hospital visits, and increasing capacity in the hematology day unit. Since the start of the programme in 2017, the majority (71) of myeloma patients at Portsmouth have been treated through the Homecare program.

Dr. De Abrew conducted a retrospective review of patients who received bortezomib between January and October 2019 aimed at determining the effectiveness of the Homecare programme. To this end, she measured the proportion able to commence the Homecare protocol; the proportion successful in completing treatment on the Homecare protocol; the amount of additional clinical nurse specialist time required to support the Homecare protocol; and the number of associated adverse incidents.

A total of 52 bortezomib-treated patients were included in the study. Patients were excluded if they were on a different combination of drugs that required hospital visits, or inpatient care for other reasons. Three patients ceased the drug – two because of toxicity, and one because of rapid progression.  The average age of patients was 74 years, and 55.8% were using bortezomib as first-line, 36.5% second-line, and the remainder third-line or more.

The vast majority started the Homecare protocol (45/52), and 25 self-administered and 17 received a relative’s help. A total of 43 completed the self-administration protocol with two reverting to hospital assistance. Bortezomib was given for four to six cycles lasting around 6-8 months.

Clinical nurse specialists trained 38 patients for home care, with an average training time of 43 minutes. Two of these patients were considered unsuitable for self-administration. The remainder were trained by ward nurses or did not require training having received bortezomib previously.

A total of 20 patients required additional clinical nurse specialist time requiring an average of 55 minutes. Of those requiring additional support: Seven needed retraining; two needed the first dose delivered by a nurse specialist; two requested help from the hematology unit; and nine wanted general extra support – for example, help with injection site queries (usually administered to the abdominal area), reassurance during administration, syringe queries, administrative queries, and queries around spillages.

“Importantly, patients always have the phone number of the nurse specialist at hand. But most people managed okay, and even if they needed additional support they still got there,” remarked Dr. De Abrew.

In terms of adverse events, there were six in total. These included three reported spillages (with no harm caused), and three experienced injection site incidents (rash, pain). “We found a low number of reported adverse events,” she said.

Dr. De Abrew added that generally, many more medications were being converted to subcutaneous formulations in myeloma and other hematology conditions. “Perhaps these results could inform self-administration of other drugs. In hematology, we get so many new drugs come through every year, but we don’t get the increased resources to manage this in the day units. Broadening self-administration could really help with capacity as well as improve quality of life for the patients.

“These results show that it can be done!” she said. 

Dr. De Abrew declared no relevant conflicts of interest. Dr. Jenner declared receiving honoraria from Janssen, which manufactures branded Velcade (bortezomib).

Since the start of the programme in 2017, the majority (71) of myeloma patients at Portsmouth have been treated through the Homecare program.

Dr. De Abrew conducted a retrospective review of patients who received bortezomib between January and October 2019 aimed at determining the effectiveness of the Homecare programme. To this end, she measured the proportion able to commence the Homecare protocol; the proportion successful in completing treatment on the Homecare protocol; the amount of additional clinical nurse specialist time required to support the Homecare protocol; and the number of associated adverse incidents.

A total of 52 bortezomib-treated patients were included in the study. Patients were excluded if they were on a different combination of drugs that required hospital visits, or inpatient care for other reasons. Three patients ceased the drug – two because of toxicity, and one because of rapid progression.  The average age of patients was 74 years, and 55.8% were using bortezomib as first-line, 36.5% second-line, and the remainder third-line or more.

The vast majority started the Homecare protocol (45/52), and 25 self-administered and 17 received a relative’s help. A total of 43 completed the self-administration protocol with two reverting to hospital assistance. Bortezomib was given for four to six cycles lasting around 6-8 months.

Clinical nurse specialists trained 38 patients for home care, with an average training time of 43 minutes. Two of these patients were considered unsuitable for self-administration. The remainder were trained by ward nurses or did not require training having received bortezomib previously.

A total of 20 patients required additional clinical nurse specialist time requiring an average of 55 minutes. Of those requiring additional support: Seven needed retraining; two needed the first dose delivered by a nurse specialist; two requested help from the hematology unit; and nine wanted general extra support – for example, help with injection site queries (usually administered to the abdominal area), reassurance during administration, syringe queries, administrative queries, and queries around spillages.

“Importantly, patients always have the phone number of the nurse specialist at hand. But most people managed okay, and even if they needed additional support they still got there,” remarked Dr. De Abrew.

In terms of adverse events, there were six in total. These included three reported spillages (with no harm caused), and three experienced injection site incidents (rash, pain). “We found a low number of reported adverse events,” she said.

Dr. De Abrew added that generally, many more medications were being converted to subcutaneous formulations in myeloma and other hematology conditions. “Perhaps these results could inform self-administration of other drugs. In hematology, we get so many new drugs come through every year, but we don’t get the increased resources to manage this in the day units. Broadening self-administration could really help with capacity as well as improve quality of life for the patients.

“These results show that it can be done!” she said. 

Dr. De Abrew declared no relevant conflicts of interest. Dr. Jenner declared receiving honoraria from Janssen, which manufactures branded Velcade (bortezomib).

Matthew Lewin, MD, PhD, founder of the Center for Exploration and Travel Health at the California Academy of Sciences, was researching snakebite treatments in rural locations in preparation for an expedition to the Philippines in 2011.

The story of a renowned herpetologist from the academy, Joseph Slowinski, who was bitten by a highly venomous krait in Myanmar and couldn’t get to a hospital in time to save his life a decade earlier, weighed on the emergency room doctor.

“I concluded that I needed something small and compact and that doesn’t care what kind of snake,” Dr. Lewin said.

It didn’t exist. That set Dr. Lewin in pursuit of a modern snakebite drug, a journey that finds his Corte Madera, Calif., company, Ophirex, nearing a promising oral treatment that fits in a pocket; is stable, easy to use, and affordable; and treats the venom from many species. “That’s the holy grail of snakebite treatment,” he said.

His work has gotten a boost with multimillion-dollar grants from a British charity and the U.S. Army. If it works – and it has been shown to work extremely well in mice and pigs – it could save tens of thousands of lives a year.

Dr. Lewin and Ophirex are not alone in their quest. Snakebites kill nearly 140,000 people a year, overwhelmingly in impoverished rural areas of Asia and Africa without adequate medical infrastructure and knowledge to administer antivenom. Though just a few people die each year in the United States from snakebites, the problem has risen to the top of the list of global health concerns in recent years. Funding has soared, and other research groups have also done promising work on new treatments. Herpetologists say deforestation and climate change are increasing human-snake encounters by forcing snakes to move to new habitats.

Dr. Lewin’s research is centered on a drug called varespladib. The enzyme inhibitor has proven itself in in-vitro lab studies and has effectively saved mice and pigs dosed with venom.

Along the way, Dr. Lewin and his team have come across another potential use for the drug. Varespladib has a positive effect on acute respiratory distress syndrome, associated with COVID-19. Next year, Ophirex will conduct human trials for the possible treatment of the condition funded with $9.9 million from the Army.

The link to a snakebite? The inflammation of the lungs caused by the coronavirus produces the sPLA2 enzyme. A more deadly version of the same enzyme is produced by snake venom.

The other companies that have come up with promising approaches to snakebite aren’t as far along as Ophirex. At the University of California-Irvine, chemist Ken Shea and his team created a nanogel – a kind of polymer used in medical applications – that blocks key proteins in the venom that cause cell destruction. At the Technical University of Denmark, Copenhagen, Andreas Laustsen is looking at engineering bacteria to manufacture anti-venom in fermentation tanks.

The days of incising a snakebite and sucking out the poison are long over, but the current treatment for venomous snakebites remains archaic.

Since the early 1900s, antivenom has been made by injecting horses or other animals with venom milked from snakes and diluted. The animals’ immune systems generate antibodies over several months, and blood plasma is taken from the animals and antibodies extracted from it.

It’s extremely expensive. Hospitals in the United States can charge as much as $15,000 a vial – and a single snakebite might require anywhere from 4 to 50 vials. Moreover, antivenom exists for little more than half the world’s species of venomous snakes.

A major problem is the roughly 2 hours it takes on average for a snakebite victim to reach a hospital and begin treatment. The chemical weapon that is venom starts immediately to destroy cells as it digests its next meal, making fast treatment essential to saving lives and preventing tissue loss.

“The two-hour window between fang and needle is where the most damage occurs,” said Leslie Boyer, director of the University of Arizona’s Venom Immunochemistry, Pharmacology and Emergency Response (VIPER) Institute. “We have a saying, ‘Time is tissue.’ ”

That’s why the search for a new snakebite drug has focused on an inexpensive treatment that can be taken into the field. Dr. Lewin’s drug wouldn’t replace antivenom. Instead, he thinks of it as the first line of defense until the victim can reach a hospital for antivenom treatment.

Dr. Lewin said he expects the drug to be inexpensive, so people in regions where snakebites are common can afford it.

Venom is extremely complicated chemically, and Dr. Lewin began his search by sussing out which of its myriad components to block. He zeroed in on the sPLA2 enzyme.

Surveying the literature about drugs that had been clinically tested for other conditions, he came across varespladib. It had been developed jointly by Eli Lilly and Shionogi, a Japanese pharmaceutical company, as a possible treatment for sepsis. They had never taken it to market.

If it worked, Dr. Lewin could license the right to produce the drug, which had already been thoroughly studied and was shown to be safe.

He placed venom in an array of test tubes. Varespladib and other drugs were added to the venom. He then added a reagent. If the venom was still active, the solution would turn yellow; if it was neutralized, it would remain clear.

The vials with varespladib “came up completely blank,” he said. “It was so stunning I said, ‘I must have made a mistake.’ ”

With a small grant, he sent the drug to the Yale Center for Molecular Discovery and found that varespladib effectively neutralized the venom of snakes found on six continents. The results were published in the journal Toxins and sent ripples through the small community of snakebite researchers.

Dr. Lewin then conducted tests on mice and pigs. Both were successful.

Human clinical trials are next, but they have been delayed by the pandemic. They are scheduled to get underway next spring.

Along the way, Dr. Lewin was fortunate enough to make some good connections that led to funding. In 2012, he attended a party at the Mill Valley, Calif., home of Jerry Harrison, the former guitarist and keyboardist for Talking Heads. Mr. Harrison had long been interested in business and start-ups – he said he was the most careful reader of the ’80s band’s contracts – and at the party he asked “if anyone had any ideas lying fallow,” Mr. Harrison said.

“And Matt pipes up and says, ‘I have this idea how to prevent people from dying from snakebites,’ ” Mr. Harrison said.

The musician said he was a bit taken aback by such an unusual and dire problem, but “I thought if it can save lives we have to do it,” he said. He became an investor and cofounder of Ophirex with Dr. Lewin.

Dr. Lewin met Lt. Col. Rebecca Carter, a biochemist who was assigned to lead the Medical Modernization Division of Air Force Special Operations Command, in 2016 when she attended a Venom Week conference in Greenville, N.C. He was presenting the results of his mouse studies. She told him about her first mission: to find a universal antivenom for medics on special operations teams in Africa. She persuaded the Special Operations Command Biomedical Research Advisory Group, which specializes in getting critical projects to production, to grant Ophirex $148,000 in 2017. She later retired from the Air Force and now works for Ophirex as vice president.

More multimillion-dollar grants followed, including the Army’s COVID grant. Clinical trials are scheduled to begin this winter.

Despite the progress and the sudden cash flow, Dr. Lewin tamps down talk of a universal snakebite cure. “There’s enough evidence to say the drug deserves to have its day in clinical trials,” he said.

Choosing which hospitalized COVID-19 patients receive potentially lifesaving care, making urgent calls for ventilators and other equipment, and triaging care based on patient age and comorbidities were among the challenges revealed in new feedback from health care leaders and frontline workers.

Even though many hospitals have contingency plans for how to allocate resources and triage patient care during crisis capacity, for many providers during the real-world COVID-19 trial of these protocols, they fell short.

Many hospital crisis capacity plans, for example, were too general to address all the specific challenges arising during the pandemic, investigators report in a study published online Nov. 6 in JAMA Network Open.

“Our research shows that the types of challenges and approach to resource limitation in real-world clinical settings during the pandemic differed in practice from how we had prepared in theory,” lead author Catherine Butler, MD, told Medscape Medical News. Insufficient dialysis treatment time, staff shortages, and routine supply scarcity are examples “for which there was not an established plan or approach for appropriate allocation.”

“This left frontline clinicians to determine what constituted an acceptable standard of care and to make difficult allocation decisions at the bedside,” added Butler, acting instructor in the Division of Nephrology at the University of Washington in Seattle and a research fellow at the VA Health Services Research and Development Seattle-Denver Center of Innovation.

The investigators conducted semistructured interviews in April and May with 61 clinicians and health leaders. Mean age was 46 years, 63% were women, and participants practiced in 15 states. Most participants hailed from locations hard-hit by the pandemic at the time, including Seattle, New York City, and New Orleans.
 

Triage tribulations

The qualitative study included comments from respondents on three major themes that emerged: planning for crisis capacity, adapting to resource limitation, and the multiple unprecedented barriers to care delivery.

Overall, planning and support from institutional leaders varied. One provider said, “Talking to administration, and they just seemed really disengaged with the problem. We asked multiple times if there was a triage command center or a plan for what would occur if we got to the point where we had to triage resources. They said there was, but they wouldn’t provide it to us.”

Another had a more positive experience. “The biggest deal in the ethics world in the last 2 months has been preparing in case we need to triage. So, we have a very detailed, elaborate, well thought-out triage policy … that was done at the highest levels of the system.”

Clinicians said they participate on triage teams – despite the moral weight and likely emotional burden – out of a sense of duty.

Interestingly, some providers on these teams also reported a reluctance to reveal their participation to colleagues. “I didn’t feel like I should tell anybody … even some of my close friends who are physicians and nurses here … that I’ve been asked to be on this [triage team],” one respondent said. “I didn’t feel like I should make it known.”
 

Adapting to scarce resources

Multiple providers said they faced difficult care decisions because of limited dialysis or supply shortages. “They felt that this patient had the greatest likelihood of benefiting from most aggressive therapy. … I think there was probably like 5 or 6 patients in the ICU … and then you had this 35-year-old with no comorbidities,” one respondent said. “That’s who the ICU dialyzed, and I couldn’t really disagree.”

“I emailed all of [my colleagues], and I said ‘Help! We need X, we need CRRT [continuous renal replacement therapy] machines, we need dialysates,’ “ another responded.

“One of the attendings had a tweet when we were running out of CRRT. He had a tweet about, ‘Can anybody give us supplies for CRRT?’ So, it got to that. You do anything. You get really desperate,” the clinician said.

Other providers reported getting innovative under the circumstances. “My partner’s son, he actually borrowed a couple of 3D printers. He printed some of these face shields, and then they got the formula, or the specifics as to how to make this particular connection to connect to a dialysis machine to generate dialysate. So, he also printed some of those from the 3D printer.”
 

Dire situations with dialysis

Another respondent understood the focus on ventilators and ICU beds throughout the crisis, but said “no one has acknowledged that dialysis has been one of the most, if not the most, limited resources.”

Another clinician expressed surprise at a decision made in the face of limited availability of traditional dialysis. “A month ago, people said we were going to do acute peritoneal dialysis [PD]. And I said, ‘No, we’re not going to do acute PD. PD, it’s not that great for acute patients, sick people in the ICUs. I don’t think we’re going to do PD.’

“Three days later we were doing acute PD. I mean, that was unbelievable!”

Some institutions rationed dialysis therapy. “We went through the entire list at the beginning of the week and [said], this person has to dialyze these days, this person would probably benefit from a dialysis session, a third group person we could probably just string along and medically manage if we needed to,” one provider said.

Another respondent reported a different strategy. “No one was not getting dialysis, but there were a lot of people getting minimal dialysis. Even though people were getting treated, resources were very stretched.”
 

Changing family dynamics

COVID-19 has naturally changed how clinicians speak with families. One respondent recalled looking at the ICU physician and being like, ‘Have you talked to the son this week?’ And she’s like, ‘Oh my God, no. … Did you talk to the son?’ I’m like, ‘Oh my God, no.’ “

They realized, the respondent added, “that none of us had called the family because it’s just not in your workflow. You’re so used to the family being there.”

Multiple providers also feared a conversation with family regarding necessary changes to care given the limitation of resources during the pandemic.

“Most families have been actually very understanding. This is a crisis, and we’re in a pandemic, and we’re all doing things we wouldn’t normally do.”

Another respondent said, “We were pretty honest about how resources were limited and how we were doing with this COVID-19 surge. And I think we talked about how the usual ability to provide aggressive dialysis was not the case with COVID-19. There was a lot of understanding, sometimes to my surprise. I would think people would be more upset when hearing something like that.”

Many clinicians facing these challenges experience moral distress, the researchers noted.

“Early in the pandemic, it became quickly apparent that possible resource limitation, such as scarce ventilators, was a major ethical concern. There was robust debate and discussion published in medical journals and the popular press about how to appropriately allocate health care resources,” the University of Washington’s Butler said.

“Transparency, accountability, and standardized processes for rationing these resources in ‘crisis capacity’ settings were seen as key to avoiding the impact of implicit bias and moral distress for clinicians,” she added.
 

Lessons learned

In terms of potential solutions that could mitigate these challenges in the future, health care leaders “could develop standardized protocols or guidelines for allocating a broader range of potentially scarce health care resources even before ‘crisis capacity’ is declared,” Butler said.

Furthermore, no frontline worker should have to go it alone. “Medical ethicists and/or other clinicians familiar with ethical considerations in settings of scarce health care resources might provide bedside consultation and collaborate with frontline providers who must grapple with the impact of more subtle forms of resource limitation on clinical decision-making.”

The study was partially funded by grants from the National Institute of Diabetes and Digestive and Kidney Diseases and a COVID-19 Research Award from the University of Washington Institute of Translational Health Sciences given to Butler.

“This left frontline clinicians to determine what constituted an acceptable standard of care and to make difficult allocation decisions at the bedside,” added Butler, acting instructor in the Division of Nephrology at the University of Washington in Seattle and a research fellow at the VA Health Services Research and Development Seattle-Denver Center of Innovation.

The investigators conducted semistructured interviews in April and May with 61 clinicians and health leaders. Mean age was 46 years, 63% were women, and participants practiced in 15 states. Most participants hailed from locations hard-hit by the pandemic at the time, including Seattle, New York City, and New Orleans.
 

Triage tribulations

The qualitative study included comments from respondents on three major themes that emerged: planning for crisis capacity, adapting to resource limitation, and the multiple unprecedented barriers to care delivery.

Overall, planning and support from institutional leaders varied. One provider said, “Talking to administration, and they just seemed really disengaged with the problem. We asked multiple times if there was a triage command center or a plan for what would occur if we got to the point where we had to triage resources. They said there was, but they wouldn’t provide it to us.”

Another had a more positive experience. “The biggest deal in the ethics world in the last 2 months has been preparing in case we need to triage. So, we have a very detailed, elaborate, well thought-out triage policy … that was done at the highest levels of the system.”

Clinicians said they participate on triage teams – despite the moral weight and likely emotional burden – out of a sense of duty.

Interestingly, some providers on these teams also reported a reluctance to reveal their participation to colleagues. “I didn’t feel like I should tell anybody … even some of my close friends who are physicians and nurses here … that I’ve been asked to be on this [triage team],” one respondent said. “I didn’t feel like I should make it known.”
 

Adapting to scarce resources

Multiple providers said they faced difficult care decisions because of limited dialysis or supply shortages. “They felt that this patient had the greatest likelihood of benefiting from most aggressive therapy. … I think there was probably like 5 or 6 patients in the ICU … and then you had this 35-year-old with no comorbidities,” one respondent said. “That’s who the ICU dialyzed, and I couldn’t really disagree.”

“I emailed all of [my colleagues], and I said ‘Help! We need X, we need CRRT [continuous renal replacement therapy] machines, we need dialysates,’ “ another responded.

“One of the attendings had a tweet when we were running out of CRRT. He had a tweet about, ‘Can anybody give us supplies for CRRT?’ So, it got to that. You do anything. You get really desperate,” the clinician said.

Other providers reported getting innovative under the circumstances. “My partner’s son, he actually borrowed a couple of 3D printers. He printed some of these face shields, and then they got the formula, or the specifics as to how to make this particular connection to connect to a dialysis machine to generate dialysate. So, he also printed some of those from the 3D printer.”
 

Dire situations with dialysis

Another respondent understood the focus on ventilators and ICU beds throughout the crisis, but said “no one has acknowledged that dialysis has been one of the most, if not the most, limited resources.”

Another clinician expressed surprise at a decision made in the face of limited availability of traditional dialysis. “A month ago, people said we were going to do acute peritoneal dialysis [PD]. And I said, ‘No, we’re not going to do acute PD. PD, it’s not that great for acute patients, sick people in the ICUs. I don’t think we’re going to do PD.’

“Three days later we were doing acute PD. I mean, that was unbelievable!”

Some institutions rationed dialysis therapy. “We went through the entire list at the beginning of the week and [said], this person has to dialyze these days, this person would probably benefit from a dialysis session, a third group person we could probably just string along and medically manage if we needed to,” one provider said.

Another respondent reported a different strategy. “No one was not getting dialysis, but there were a lot of people getting minimal dialysis. Even though people were getting treated, resources were very stretched.”
 

Changing family dynamics

COVID-19 has naturally changed how clinicians speak with families. One respondent recalled looking at the ICU physician and being like, ‘Have you talked to the son this week?’ And she’s like, ‘Oh my God, no. … Did you talk to the son?’ I’m like, ‘Oh my God, no.’ “

They realized, the respondent added, “that none of us had called the family because it’s just not in your workflow. You’re so used to the family being there.”

Multiple providers also feared a conversation with family regarding necessary changes to care given the limitation of resources during the pandemic.

“Most families have been actually very understanding. This is a crisis, and we’re in a pandemic, and we’re all doing things we wouldn’t normally do.”

Another respondent said, “We were pretty honest about how resources were limited and how we were doing with this COVID-19 surge. And I think we talked about how the usual ability to provide aggressive dialysis was not the case with COVID-19. There was a lot of understanding, sometimes to my surprise. I would think people would be more upset when hearing something like that.”

Many clinicians facing these challenges experience moral distress, the researchers noted.

“Early in the pandemic, it became quickly apparent that possible resource limitation, such as scarce ventilators, was a major ethical concern. There was robust debate and discussion published in medical journals and the popular press about how to appropriately allocate health care resources,” the University of Washington’s Butler said.

“Transparency, accountability, and standardized processes for rationing these resources in ‘crisis capacity’ settings were seen as key to avoiding the impact of implicit bias and moral distress for clinicians,” she added.
 

Lessons learned

In terms of potential solutions that could mitigate these challenges in the future, health care leaders “could develop standardized protocols or guidelines for allocating a broader range of potentially scarce health care resources even before ‘crisis capacity’ is declared,” Butler said.

Furthermore, no frontline worker should have to go it alone. “Medical ethicists and/or other clinicians familiar with ethical considerations in settings of scarce health care resources might provide bedside consultation and collaborate with frontline providers who must grapple with the impact of more subtle forms of resource limitation on clinical decision-making.”

The study was partially funded by grants from the National Institute of Diabetes and Digestive and Kidney Diseases and a COVID-19 Research Award from the University of Washington Institute of Translational Health Sciences given to Butler.

Choosing which hospitalized COVID-19 patients receive potentially lifesaving care, making urgent calls for ventilators and other equipment, and triaging care based on patient age and comorbidities were among the challenges revealed in new feedback from health care leaders and frontline workers.

Even though many hospitals have contingency plans for how to allocate resources and triage patient care during crisis capacity, for many providers during the real-world COVID-19 trial of these protocols, they fell short.

Many hospital crisis capacity plans, for example, were too general to address all the specific challenges arising during the pandemic, investigators report in a study published online Nov. 6 in JAMA Network Open.

“Our research shows that the types of challenges and approach to resource limitation in real-world clinical settings during the pandemic differed in practice from how we had prepared in theory,” lead author Catherine Butler, MD, told Medscape Medical News.

Initial evidence suggests that the deliberate delays in melanoma care that occurred during the COVID-19 shelter-in-place lockdown last spring had a significant negative impact on patient outcomes, Rebecca I. Hartman, MD, MPH, said at a virtual forum on cutaneous malignancies jointly presented by Postgraduate Institute for Medicine and Global Academy for Medication Education.

This is not what National Comprehensive Cancer Network officials expected when they issued short-term recommendations on how to manage cutaneous melanoma during the first wave of the COVID-19 pandemic. Those recommendations for restriction of care, which Dr. Hartman characterized as “pretty significant changes from how we typically practice melanoma care in the U.S.,” came at a time when there was justifiable concern that the first COVID-19 surge would strain the U.S. health care system beyond the breaking point.

The rationale given for the NCCN recommendations was that most time-to-treat studies have shown no adverse patient outcomes for 90-day delays in treatment, even for thicker melanomas. But those studies, all retrospective, have been called into question. And the first real-world data on the impact of care restrictions during the lockdown, reported by Italian dermatologists, highlights adverse effects with potentially far-reaching consequences, noted Dr. Hartman, director of melanoma epidemiology at Brigham and Women’s Hospital and a dermatologist, Harvard University, Boston.

Analysis of the impact of lockdown-induced delays in melanoma care is not merely an academic exercise, she added. While everyone hopes that the spring 2020 COVID-19 shelter-in-place was a once-in-a-lifetime event, there’s no guarantee that will be the case. Moreover, the lockdown provides a natural experiment addressing the possible consequences of melanoma care delays on patient outcomes, a topic that for ethical reasons could never be addressed in a randomized trial.

The short-term NCCN recommendations included the use of excisional biopsies for melanoma diagnosis whenever possible; and delay of up to 3 months for wide local excision of in situ melanoma, any invasive melanoma with negative margins, and even T1 melanomas with positive margins provided the bulk of the lesion had been excised. The guidance also suggested delaying sentinel lymph node biopsy (SLNB), along with increased use of neoadjuvant therapy in patients with clinically palpable regional lymph nodes in order to delay surgery for up to 8 weeks. Single-agent systemic therapy at the least-frequent dosing was advised in order to minimize toxicity and reduce the need for additional health care resources: for example, nivolumab (Opdivo) at 480 mg every 4 weeks instead of every 2 weeks, and pembrolizumab (Keytruda) at 400 mg every 6 weeks, rather than every 3 weeks.

So, that’s what the NCCN recommended. Here’s what actually happened during shelter-in-place as captured in Dr. Hartman’s survey of 18 U.S. members of the Melanoma Prevention Working Group, all practicing dermatology in centers particularly hard-hit in the first wave of the pandemic: In-person new melanoma patient visits plunged from an average of 4.83 per week per provider to 0.83 per week. Telemedicine visits with new melanoma patients went from zero prepandemic to 0.67 visits per week per provider, which doesn’t come close to making up for the drop in in-person visits. Interestingly, two respondents reported turning to gene-expression profile testing for patient prognostication because of delays in SLNB.

Wide local excision was delayed by an average of 6 weeks in roughly one-third of melanoma patients with early tumor stage disease, regardless of margin status. For patients with stage T1b disease, wide local excision was typically performed on time during shelter-in-place; however, SLNB was delayed by an average of 5 weeks in 22% of patients with positive margins and 28% of those with negative margins. In contrast, 80% of patients with more advanced T2-T4 melanoma underwent on-schedule definitive management with wide local excision and SLNB, Dr. Hartman reported.

Critics have taken issue with the NCCN’s conclusion that most time-to-treatment studies show no harm arising from 90-day treatment delays. A review of the relevant published literature by Dr. Hartman’s Harvard colleagues, published in July, found that the evidence is mixed. “There is insufficient evidence to definitively conclude that delayed wide resection after gross removal of the primary melanoma is without harm,” they concluded in the review.

Spanish dermatologists performed a modeling study in order to estimate the potential impact of COVID-19 lockdowns on 5- and 10-year survival of melanoma patients. Using the growth rate of a random sample of 1,000 melanomas to model estimates of tumor thickness after various delays, coupled with American Joint Committee on Cancer survival data for different T stages, they estimated that 5-year survival would be reduced from 94.2% to 92.3% with a 90-day delay in diagnosis, and that 10-year survival would drop from 90.0% to 87.6%.

But that’s merely modeling. Francesco Ricci, MD, PhD, and colleagues from the melanoma unit at the Istituto Dermopatico dell’Immacolata, Rome, have provided a first look at the real-world impact of the lockdown. In the prelockdown period of January through March 9th, 2020, the referral center averaged 2.3 new melanoma diagnoses per day. During the Rome lockdown, from March 10th through May 3rd, this figure dropped to a mean of 0.6 melanoma diagnoses per day. Postlockdown, from May 4th to June 6th, the average climbed to 1.3 per day. The rate of newly diagnosed nodular melanoma was 5.5-fold greater postlockdown, compared with prelockdown; the rate of ulcerated melanoma was 4.9-fold greater.

“We can hypothesize that this may have been due to delays in diagnosis and care,” Dr. Hartman commented. “This is important because we know that nodular melanoma as well as ulceration tend to have a worse prognosis in terms of mortality.”

The mean Breslow thickness of newly diagnosed melanomas was 0.88 mm prelockdown, 0.66 mm during lockdown, and 1.96 mm postlockdown. The investigators speculated that the reduced Breslow thickness of melanomas diagnosed during lockdown might be explained by a greater willingness of more health-conscious people to defy the shelter-in-place instructions because of their concern about a suspicious skin lesion. “Though it is way too early to gauge the consequences of such diagnostic delay, should this issue be neglected, dermatologists and their patients may pay a higher price later with increased morbidity, mortality, and financial burden,” according to the investigators.

Dr. Hartman observed that it will be important to learn whether similar experiences occurred elsewhere during lockdown.

Another speaker, John M. Kirkwood, MD, said he has seen several melanoma patients referred from outside centers who had delays of up to 3 months in sentinel lymph node management of T2 and T3 tumors during lockdown who now have widespread metastatic disease.

“Now, is that anecdotal? I don’t know, it’s just worrisome to me,” commented Dr. Kirkwood, professor of medicine, dermatology, and translational science at the University of Pittsburgh.

Merrick Ross, MD, professor of surgical oncology at M.D. Anderson Cancer Center, Houston, recalled, “There was a period of time [during the lockdown] when we weren’t allowed to do certain elective procedures, if you want to call cancer surgery elective.”

“It’s too soon to talk about outcomes because a lot of patients are still in the process of being treated after what I would consider a significant delay in diagnosis,” the surgeon added.

An audience member asked if there will be an opportunity to see data on the damage done by delaying melanoma management as compared to lives saved through the lockdown for COVID-19. Dr. Ross replied that M.D. Anderson is in the midst of an institution-wide study analyzing the delay in diagnosis of a range of cancers.

“In our melanoma center it is absolutely clear, although we’re still collecting data, that the median tumor thickness is much higher since the lockdown,” Dr. Ross commented.

Dr. Hartman said she and her coinvestigators in the Melanoma Prevention Working Group are attempting to tally up the damage done via the lockdown by delaying melanoma diagnosis and treatment. But she agreed with the questioner that the most important thing is overall net lives saved through shelter-in-place.

“I’m sure that, separately, nondermatologists – perhaps infectious disease doctors and internists – are looking at how many lives were saved by the lockdown policy. So I do think all that data will come out,” Dr. Hartman predicted.

She reported having no financial conflicts regarding her presentation.

For patients with stage T1b disease, wide local excision was typically performed on time during shelter-in-place; however, SLNB was delayed by an average of 5 weeks in 22% of patients with positive margins and 28% of those with negative margins. In contrast, 80% of patients with more advanced T2-T4 melanoma underwent on-schedule definitive management with wide local excision and SLNB, Dr. Hartman reported.

Critics have taken issue with the NCCN’s conclusion that most time-to-treatment studies show no harm arising from 90-day treatment delays. A review of the relevant published literature by Dr. Hartman’s Harvard colleagues, published in July, found that the evidence is mixed. “There is insufficient evidence to definitively conclude that delayed wide resection after gross removal of the primary melanoma is without harm,” they concluded in the review.

Spanish dermatologists performed a modeling study in order to estimate the potential impact of COVID-19 lockdowns on 5- and 10-year survival of melanoma patients. Using the growth rate of a random sample of 1,000 melanomas to model estimates of tumor thickness after various delays, coupled with American Joint Committee on Cancer survival data for different T stages, they estimated that 5-year survival would be reduced from 94.2% to 92.3% with a 90-day delay in diagnosis, and that 10-year survival would drop from 90.0% to 87.6%.

But that’s merely modeling. Francesco Ricci, MD, PhD, and colleagues from the melanoma unit at the Istituto Dermopatico dell’Immacolata, Rome, have provided a first look at the real-world impact of the lockdown. In the prelockdown period of January through March 9th, 2020, the referral center averaged 2.3 new melanoma diagnoses per day. During the Rome lockdown, from March 10th through May 3rd, this figure dropped to a mean of 0.6 melanoma diagnoses per day. Postlockdown, from May 4th to June 6th, the average climbed to 1.3 per day. The rate of newly diagnosed nodular melanoma was 5.5-fold greater postlockdown, compared with prelockdown; the rate of ulcerated melanoma was 4.9-fold greater.

“We can hypothesize that this may have been due to delays in diagnosis and care,” Dr. Hartman commented. “This is important because we know that nodular melanoma as well as ulceration tend to have a worse prognosis in terms of mortality.”

The mean Breslow thickness of newly diagnosed melanomas was 0.88 mm prelockdown, 0.66 mm during lockdown, and 1.96 mm postlockdown. The investigators speculated that the reduced Breslow thickness of melanomas diagnosed during lockdown might be explained by a greater willingness of more health-conscious people to defy the shelter-in-place instructions because of their concern about a suspicious skin lesion. “Though it is way too early to gauge the consequences of such diagnostic delay, should this issue be neglected, dermatologists and their patients may pay a higher price later with increased morbidity, mortality, and financial burden,” according to the investigators.

Dr. Hartman observed that it will be important to learn whether similar experiences occurred elsewhere during lockdown.

Another speaker, John M. Kirkwood, MD, said he has seen several melanoma patients referred from outside centers who had delays of up to 3 months in sentinel lymph node management of T2 and T3 tumors during lockdown who now have widespread metastatic disease.

“Now, is that anecdotal? I don’t know, it’s just worrisome to me,” commented Dr. Kirkwood, professor of medicine, dermatology, and translational science at the University of Pittsburgh.

Merrick Ross, MD, professor of surgical oncology at M.D. Anderson Cancer Center, Houston, recalled, “There was a period of time [during the lockdown] when we weren’t allowed to do certain elective procedures, if you want to call cancer surgery elective.”

“It’s too soon to talk about outcomes because a lot of patients are still in the process of being treated after what I would consider a significant delay in diagnosis,” the surgeon added.

An audience member asked if there will be an opportunity to see data on the damage done by delaying melanoma management as compared to lives saved through the lockdown for COVID-19. Dr. Ross replied that M.D. Anderson is in the midst of an institution-wide study analyzing the delay in diagnosis of a range of cancers.

“In our melanoma center it is absolutely clear, although we’re still collecting data, that the median tumor thickness is much higher since the lockdown,” Dr. Ross commented.

Dr. Hartman said she and her coinvestigators in the Melanoma Prevention Working Group are attempting to tally up the damage done via the lockdown by delaying melanoma diagnosis and treatment. But she agreed with the questioner that the most important thing is overall net lives saved through shelter-in-place.

“I’m sure that, separately, nondermatologists – perhaps infectious disease doctors and internists – are looking at how many lives were saved by the lockdown policy. So I do think all that data will come out,” Dr. Hartman predicted.

She reported having no financial conflicts regarding her presentation.

For patients with malignant colorectal polyps, endoscopists should look for features of deep submucosal invasion and should retrieve, handle, and submit specimens in ways that support thorough and accurate pathologic assessment, according to new recommendations from the US Multi-Society Task Force on Colorectal Cancer.

“In nonpedunculated lesions with features of deep submucosal invasion, endoscopic biopsy is followed by surgical resection. In cases without features of deep submucosal invasion, en bloc resection and proper specimen handling should be considered (if feasible) for lesions with a high risk of superficial submucosal invasion,” wrote Aasma Shaukat, MD, MPH, of the Minneapolis Veterans Affairs Health Care System and her fellow experts. The recommendations were published in Gastroenterology.

Malignant colorectal polyps invade the submucosa but do not extend into the muscularis propria. Pedunculated and nonpedunculated polyps should be considered to invade the deep submucosa if they are classified as NICE (NBI International Colorectal Endoscopic) type 3, Kudo type VN (neoplastic and invasive, with an irregular arrangement), or Kudo type VI (an amorphous structure, with a loss of or decrease in pits). “Nonpedunculated lesions with these features should be biopsied (in the area of surface feature disruption), tattooed (unless in or near the cecum), and referred to surgery. Pedunculated polyps with features of deep submucosal invasion should undergo endoscopic polypectomy,” according to the MSTFCC recommendations.

Moderate-quality evidence links submucosal invasion with two types of polyp morphology: LST-NG (laterally spreading tumor, nongranular type) showing a depression or sessile shape and LST-G (laterally spreading tumor, granular type) that includes a dominant nodule. According to low-quality evidence, these lesions should be managed with en bloc rather than piecemeal resection. En bloc resection is important for all pedunculated polyps (even if large) and should be considered for LST-G lesions with a dominant nodule. Resected pedunculated polyps should be retrieved through the suction channel – if doing so does not require them to be cut – or with a net or snare during scope withdrawal. Nonpedunculated lesions with suspected submucosal invasion that are removed en bloc should be pinned peripherally around the entire circumference to a hard surface and fixed in 10% formalin. This practice helps pathologists orient specimens to correctly assess depth of invasion and margin involvement.

For both pedunculated and nonpedunculated polyps, features denoting a high risk for residual or recurrent malignancy are poor tumor differentiation, lymphovascular invasion, or more than 1 mm of submucosal invasion. For nonpedunculated polyps, additional high-risk features include tumor budding and tumor involvement of the cautery margin. The MSTFCC recommends that, when reporting on a malignant colorectal polyp, pathologists follow the structured template of the College of American Pathologists and note the lesion’s histologic type, grade of differentiation, extent of tumor extension or invasion, stalk and mucosal margin, and presence or absence of lymphovascular invasion. Specimen integrity, polyp size and morphology, and tumor budding are also useful. To reduce miscommunication and facilitate appropriate management, pathologists should avoid using the terms carcinoma and cancer when describing malignant colorectal polyps, according to the MSTFCC.

The decision to recommend adjuvant surgery “is based on polyp shape, whether there was en bloc resection and adequate histologic assessment, the presence or absence of unfavorable histologic features, the patient’s risk for surgical mortality and morbidity, and patient preferences,” the recommendations state. Because multidisciplinary management can optimize clinical outcomes for patients with malignant polyps, gastroenterologists, pathologists, oncologists, and surgeons should identify best ways to communicate with each other and share decision-making conjointly and with patients. “Patient values are important in cases where the risk of residual cancer and the risk of surgical mortality are similar,” the MSTFCC notes. “In these latter cases, shared decision-making is emphasized.”

The authors of the task force recommendations reported having no relevant conflicts of interest since 2016.

EVIDENCE SUMMARY

A meta-analysis of 6 RCTs studied the effect of smartphone self-care applications on A1C, weight, blood pressure, and lipids in adult patients with T2DM. All the interventions comprised 4 components: electronic self-management prompts and reminders, personal measuring devices, patient-driven data upload, and remote analysis of the data with feedback. The review excluded studies that used phone calls or lasted fewer than 3 months.

Some improvement in A1C found, but no effect on weight

Telehealth interventions improved A1C more than usual care (6 trials, 884 patients; mean difference = –0.40%; 95% CI, –0.69% to –0.11%).¹ A subset of 4 studies with 560 patients evaluated changes in weight. Patients had a mean age of 61 years and average weight of 84 kg (in 3 of 4 studies reporting baseline weight). Aggregate weight loss was insignificant after 3 to 12 months (mean difference = –0.84 kg; 95% CI, –2.04 kg to 0.36 kg, P = .17). Investigators reported no harms. Limitations of the analysis included high heterogeneity in the main outcome of A1C (I² = 70%) but low heterogeneity within the 4 studies assessing weight (I² = 30%).

Other, small studies found no change in A1C

Two subsequent small RCTs came to different conclusions than the meta-analysis. One compared the impact of individualized physical activity–based text messages in response to pedometer readings with pedometer use alone.² It included 126 adult patients (mean age, 50.5 years) with T2DM who had an A1C > 7% and access to an Internet-connected computer. Researchers excluded patients who were unable to perform moderate physical activity or who had cognitive deficits.

At enrollment, researchers supplied all patients with a pedometer and an appointment with a counselor to set goals for physical activity. They sent 2 text messages daily to the intervention group (and none to the control group) based on uploaded pedometer data. One message detailed physical activity progress and the second encouraged increased physical activity. The primary outcome was mean step counts per month; secondary outcomes included A1C and weight measured at 6 months.

The groups showed no significant difference in A1C (mean difference = 0.07%; 95% CI, –0.47% to 0.34%, P = .75) or weight loss (mean difference = 3.1 lb; 95% CI, –24.5 lb to 18.3 lb, P = .77). Many patients (43%) reported difficulty uploading step counts, receiving texts, and responding to texts. The dropout rate was 24%.

A second RCT with 150 patients, using a less elaborate protocol, assessed the effectiveness of tailored text-message reminders compared with nontailored text messages to improve A1C and body mass index (BMI).³ Patients were adult Iranians (mean age, 52.5 years) with T2DM who owned a cell phone and could receive and read text messages.

Patients filled out a diabetic self-care assessment to identify barriers to improving care and were randomized into 3 groups. The first group received tailored text messages (75% addressing the patient’s top 2 barriers to self-care and 25% general messages). The second group received nontailored text messages of encouragement. The control group received no text messages.

Continue to: After 3 months...

After 3 months, BMI was reduced in both messaging groups but not the control group (tailored text = –0.6 kg/m², nontailored text = –0.5 kg/m², controls = 0.7 kg/m²; P < .05). A1C levels didn’t change significantly. One limitation of the study was that 30% to 35% of the patients in the intervention group had a university-level education, compared with 12% in the control group.

Recommendations

The Department of Veterans Affairs issued guidelines in 2017 regarding management of patients with T2DM in primary care.⁴ The guidelines state that all patients should receive individualized self-management education using “modalities tailored to their preferences” (strong recommendation). They further recommend “offering one or more bidirectional telehealth interventions” in coordination with patients’ health care providers (weak recommendation).

Telehealth interventions may be associated with a decrease in hemoglobin A1C.

The 2017 diabetes self-management recommendations endorsed by the American Diabetes Association state that “strong evidence” shows that incorporating text messaging into diabetes care improves outcomes, enhances feedback loops, and empowers patients.⁵

Editor’s takeaway

Telehealth offers mechanisms for patients and physicians to enhance communication about health behaviors and health status. But does it alter outcomes? The cited literature suggests that benefits aren’t a forgone conclusion and that acceptability, ease of use, cost, and individualization are critical issues in telehealth design.
