CTO PCI success rates rising, with blip during COVID-19, registry shows

Article Type
Changed

Technical and procedural success rates for chronic total occlusion percutaneous coronary intervention (CTO PCI) have increased steadily over the past 6 years, with rates of in-hospital major adverse cardiac events (MACE) declining to the 2%-or-lower range in that time.

“CTO PCI technical and procedural success rates are high and continue to increase over time,” Spyridon Kostantinis, MD said in presenting updated results from the international PROGRESS-CTO registry at the Society for Cardiovascular Angiography & Interventions annual scientific sessions.

“The overall success rate increased from 81.6% in 2018 to 88.1% in 2021,” he added. The overall incidence of in-hospital MACE in that time was “an acceptable” 2.1% without significant changes over that period.

The analysis examined clinical, angiographic and procedural outcomes of 10,249 CTO PCIs performed on 10,019 patients from 63 centers in nine countries during 2016-2021. PROGRESS-CTO stands for Prospective Global Registry for the Study of Chronic Total Occlusion Intervention.

The target CTOs were highly complex, he said, with an average J-CTO (multicenter CTO registry in Japan) score of 2.4 ± 1.3 and PROGRESS-CTO score of 1.3 ± 1. The most common CTO target vessel was the right coronary artery (53%), followed by the left anterior descending artery (26%) and the circumflex artery (19%).

The registry also tracked how characteristics of the CTO PCI procedures themselves changed over time. “The septal and the epicardial collaterals were the most common collaterals used for retrograde crossing, with a decreasing trend for epicardial collaterals over time,” said Dr. Kostantinis, a research fellow at the Minneapolis Heart Institute.

Septal collateral use varied between 64% and 69% of cases from 2016 to 2021, but the share of epicardial collaterals declined from 35% to 22% in that time.

“Over time, the range of antegrade wiring as the final successfully crossing strategy increased from 46% in 2016 to 61% in 2021, with a decrease in antegrade dissection and re-entry (ADR) and no change in the retrograde approach,” Dr. Kostantinis said. The percentage of procedures using ADR as the final crossing strategy declined from 18% in 2016 to 12% in 2021, with the rate of retrograde crossings peaking at 21% in 2016 but leveling off to 18% or 19% in the subsequent years.



“An increasing use in the efficiency of antegrade wiring may reflect an improvement in guidewire retrograde crossing as well as the increasing operator expertise,” Dr. Kostantinis said.

The study also found that contrast volume, air kerma radiation dose, fluoroscopy time, and procedure time declined steadily over time. “The potential explanations for these are using new x-ray systems as well as the use of intravascular imaging,” Dr. Kostantinis said.

In 2020, the rates of technical and procedural success, as well as the number of overall procedures, declined from 2019, while MACE rates ticked upward that year, probably because of the COVID-19 pandemic, Dr. Kostantinis said.

“It is true that we noticed a rise in MACE rate from 1.6% in 2019 to 2.7% in 2020, but in 2021 that decreased again to 1.7%,” he said in an interview. “Another potential explanation is the higher angiographic complexity of CTOs treated during that year (2020) that resulted in more adverse events.”

Previous results from the PROGRESS-CTO registry reported the difference in MACE between 2019 and 2020 was significant (P  = .01). “So, yes, the difference between those 2 years is significant,” Dr. Kostantinis said. However, he noted, the overall trend was not significant, with a P value of .194.

The risk profile of CTO PCI has improved “slowly” over time, said Kirk N. Garratt, MD, but “it’s not yet were it needs to be.”

Dr. Kirk N. Garratt

He added, “Undoubtedly we’ve learned that, without any question, one method for minimizing the risk is to concentrate these cases in the hands of those that do many of them.” As the number of procedures fell – an “embedded” pandemic impact –“I worry that it’s inevitable that complication rates will tick up a bit,” said Dr. Garratt, director of the Center for Heart and Vascular Health at Christiana Care in Newark, Del.

By the same token, he added, this situation with regard to CTOs “parallels what’s happening elsewhere in interventional medicine and medicine broadly; numbers are increasing and we’re busy again. In most domains we’re not as busy as we had been prepandemic, and time will allow us to catch up.”

PROGRESS-CTO has received funding from the Joseph F. and Mary M. Fleischhacker Foundation and the Abbott Northwestern Hospital Foundation Innovation Grant.

Dr. Kostantinis has no disclosures. Dr. Garratt is an advisory board member for Abbott.

Stem cell transplants could be ‘transformational’ in type 1 diabetes

Article Type
Changed

NEW ORLEANS – Two patients with type 1 diabetes have now experienced improved blood glucose control with Vertex Pharmaceutical’s investigational allogeneic stem cell–derived islets (VX-880), with the first person now completely insulin independent at 9 months post transplant.

Prior to the procedure, both patients had hypoglycemic unawareness and had experienced multiple episodes of severe hypoglycemia, conditions considered severe enough to justify the risk of immune suppression (which is required for such stem cell–derived islet transplants as they are “foreign” to the recipient).

Dr. James Markmann

The first patient, a 64-year-old man with type 1 diabetes for more than 40 years, now has a hemoglobin A1c in the normal range without taking any insulin more than 9 months after the procedure. The second, a 35-year-old woman with type 1 diabetes for 10.7 years, experienced a 30% reduction in insulin use and significant increased time spent in target glucose range, by 5 months post transplant. Both patients were given just half the targeted VX-880 dose.

Data for those two patients – the first in Vertex’s phase 1/2 multicenter, single-arm, open-label clinical trial of VX-880 – were reported at the annual scientific sessions of the American Diabetes Association, by James F. Markmann, MD, PhD.

He has been transplanting pancreatic islet cells from deceased donors into humans via infusion into the hepatic portal vein for over 20 years.

Transplantation of pancreatic islet cells obtained from cadavers have been shown to eliminate severe hypoglycemia and improve glycemic control in patients with type 1 diabetes, but they’re limited in quantity and are of variable quality. Islets that are manufactured via differentiation from human pluripotent stem cells represent an alternative, explained Dr. Markmann, chief of the division of transplant surgery at Massachusetts General Hospital, Boston.

“This is a new area. ... We hope this will be the same or potentially better. With stem cell–derived islets the quality, consistency, and reliability might produce a better result than with cadaveric islets,” he commented during a press briefing here.

A third patient has recently received the full targeted VX-880 dose but was not part of the current report. The planned enrollment is 17 patients. The trial is currently on clinical hold per the Food and Drug Administration concerning the criteria around dose escalation, but Vertex is working with the FDA to sort that out. Meanwhile, enrollment remains open in Canada, Dr. Markmann said.

In answer to a question about how patient 1 is doing now, Dr. Markmann replied, “He’s doing great. He’s probably the most appreciative patient I’ve ever met. His life was being destroyed by diabetes. He couldn’t work. He crashed his motorcycle from [low blood sugar]. He really was tremendously appreciative that he could participate.”

When Dr. Markmann explained the potential uncertainties and risks to the patient prior to the procedure, the patient replied: “I want to participate. If I die from this and I help somebody else I’d be happy, but I can’t go on living the way I’m living.”

“These people really suffer and this, I think, brings hope to them,” Dr. Markmann said.
 

 

 

‘Beautiful data’ seen in two patients, with ‘transformational’ potential

Asked to comment, Marlon Pragnell, PhD, vice president for Research & Science at the ADA, told this news organization: “It’s beautiful data. People who have type 1 diabetes lack [pancreatic] beta cells ... it was impossible to get sufficient beta cells from cadaveric transplants. It’s just nowhere near enough. If this is safe and effective, if they continue to show safety and efficacy like patient 1, this will be transformational.”

Dr. Markmann presented data for the most recent study visit for each of the two patients, 270 days for patient 1 and 150 days for patient 2. Prior to the transplants, patient 1 had experienced five severe hypoglycemic events and patient 2 had experienced three.

Both had undetectable C-peptide levels at baseline. In response to a mixed-meal tolerance test, patient 1 showed a “robust” C-peptide response by day 90, which increased by day 180. Those levels had dropped but were still detectable by day 270, “possibly due to improved insulin sensitivity,” Dr. Markmann said.

Similarly, Patient 2 also had increased C-peptide that increased to detectable range by day 90 with improved glucose disposal.

Hemoglobin A1c dropped in patient 1 from 8.6% at baseline to 6.9% at day 180, to a “remarkable” 5.2% at day 270. For patient 2, the drop was from 7.5% to a nadir of 6.4% by day 57, then reversing back to 7.1% at day 150.  

Both patients also had significant reductions in insulin dose. For patient 1, the dose reduction was more than 90% – from 34 units at baseline to 2.6 units by day 90. By day 210 he was able to stop insulin and by day 270 he met formal criteria for insulin independence.

Patient 2 also had a significant reduction in insulin dose, from 25.9 units to 18.7 by day 57 and remained stable thereafter, at 18.2 units by day 150.

Asked why Patient 2’s results weren’t quite as impressive as patient 1’s, Dr. Markmann replied “I think what’s important is that both patients did great. And since this was a half-dose, we might have expected that the outcome was going to be more like patient 2 rather than patient 1. So, I think we’re just going to have to [study this in] more patients to understand where it falls.” 

Although patient 1 experienced a cluster of six severe hypoglycemic events early in the posttransplant period, he had no further events after day 35. Patient 2 had no severe hypoglycemic events.

Other safety events were generally consistent with that seen with the immunosuppressive regimen in the perioperative period. Patient 1 had a “mild and self-limited” rise in liver function test and also experienced two severe adverse events: A rash from the immune suppression that resolved spontaneously, and dehydration requiring hospitalization on day 186. Patient 2’s adverse events were all mild to moderate, most commonly headache and hypomagnesemia and not related to VX-880.

Immunosuppression: Work is ongoing

The immunosuppression regimen used comprises a depletion of lymphocytes at induction, followed by a maintenance regimen of two standard agents used in kidney transplant patients and found to be well tolerated, Dr. Markmann said.

Still, the risk of immunosuppression generally outweighs the potential benefit for most people with type 1 diabetes who are managing reasonably well with insulin treatment.

“This is part one of a two-part problem. One is to have a reliable, consistent, effective cell therapy. The second is to develop an approach that doesn’t require immunosuppression. ... But if we had a way of transplanting the cells without the need for immunosuppression, then it could be really widely available. That’s an opportunity for the future since these cells can be made in unlimited quantities,” Dr. Markmann commented during the press briefing.

Asked for his thoughts about the immunosuppression aspect, Dr. Pragnell told this news organization: “Immune suppression is a concern, but I feel that this is just the start of so much research in this area. They’re going to take this step by step. This is just the start. My understanding is they have additional strategies around immune suppression, and in the future they might not even need immunosuppression. But even at this stage right now, it’s amazing.”

He added: “The ‘artificial pancreas’ is a huge step forward, but it’s just a bridge to a cure, whereas if they’re able to show safety and efficacy, this is potentially a cure. ... I’m very excited about it.”

Dr. Markmann serves on advisory boards for iTolerance, eGenesis, and QihanBio. He is a consultant to Vertex Pharmaceuticals. Dr. Pragnell is an ADA employee and has no further disclosures.

Prior to the procedure, both patients had hypoglycemic unawareness and had experienced multiple episodes of severe hypoglycemia, conditions considered severe enough to justify the risk of immune suppression (which is required for such stem cell–derived islet transplants as they are “foreign” to the recipient).

Dr. James Markmann

The first patient, a 64-year-old man with type 1 diabetes for more than 40 years, now has a hemoglobin A1c in the normal range without taking any insulin more than 9 months after the procedure. The second, a 35-year-old woman with type 1 diabetes for 10.7 years, experienced a 30% reduction in insulin use and significant increased time spent in target glucose range, by 5 months post transplant. Both patients were given just half the targeted VX-880 dose.

Data for those two patients – the first in Vertex’s phase 1/2 multicenter, single-arm, open-label clinical trial of VX-880 – were reported at the annual scientific sessions of the American Diabetes Association, by James F. Markmann, MD, PhD.

He has been transplanting pancreatic islet cells from deceased donors into humans via infusion into the hepatic portal vein for over 20 years.

Transplantation of pancreatic islet cells obtained from cadavers have been shown to eliminate severe hypoglycemia and improve glycemic control in patients with type 1 diabetes, but they’re limited in quantity and are of variable quality. Islets that are manufactured via differentiation from human pluripotent stem cells represent an alternative, explained Dr. Markmann, chief of the division of transplant surgery at Massachusetts General Hospital, Boston.

“This is a new area. ... We hope this will be the same or potentially better. With stem cell–derived islets the quality, consistency, and reliability might produce a better result than with cadaveric islets,” he commented during a press briefing here.

A third patient has recently received the full targeted VX-880 dose but was not part of the current report. The planned enrollment is 17 patients. The trial is currently on clinical hold per the Food and Drug Administration concerning the criteria around dose escalation, but Vertex is working with the FDA to sort that out. Meanwhile, enrollment remains open in Canada, Dr. Markmann said.

In answer to a question about how patient 1 is doing now, Dr. Markmann replied, “He’s doing great. He’s probably the most appreciative patient I’ve ever met. His life was being destroyed by diabetes. He couldn’t work. He crashed his motorcycle from [low blood sugar]. He really was tremendously appreciative that he could participate.”

When Dr. Markmann explained the potential uncertainties and risks to the patient prior to the procedure, the patient replied: “I want to participate. If I die from this and I help somebody else I’d be happy, but I can’t go on living the way I’m living.”

“These people really suffer and this, I think, brings hope to them,” Dr. Markmann said.
 

 

 

‘Beautiful data’ seen in two patients, with ‘transformational’ potential

Asked to comment, Marlon Pragnell, PhD, vice president for Research & Science at the ADA, told this news organization: “It’s beautiful data. People who have type 1 diabetes lack [pancreatic] beta cells ... it was impossible to get sufficient beta cells from cadaveric transplants. It’s just nowhere near enough. If this is safe and effective, if they continue to show safety and efficacy like patient 1, this will be transformational.”

Dr. Markmann presented data for the most recent study visit for each of the two patients, 270 days for patient 1 and 150 days for patient 2. Prior to the transplants, patient 1 had experienced five severe hypoglycemic events and patient 2 had experienced three.

Both had undetectable C-peptide levels at baseline. In response to a mixed-meal tolerance test, patient 1 showed a “robust” C-peptide response by day 90, which increased by day 180. Those levels had dropped but were still detectable by day 270, “possibly due to improved insulin sensitivity,” Dr. Markmann said.

Similarly, Patient 2 also had increased C-peptide that increased to detectable range by day 90 with improved glucose disposal.

Hemoglobin A1c dropped in patient 1 from 8.6% at baseline to 6.9% at day 180, to a “remarkable” 5.2% at day 270. For patient 2, the drop was from 7.5% to a nadir of 6.4% by day 57, then reversing back to 7.1% at day 150.  

Both patients also had significant reductions in insulin dose. For patient 1, the dose reduction was more than 90% – from 34 units at baseline to 2.6 units by day 90. By day 210 he was able to stop insulin and by day 270 he met formal criteria for insulin independence.

Patient 2 also had a significant reduction in insulin dose, from 25.9 units to 18.7 by day 57 and remained stable thereafter, at 18.2 units by day 150.

Asked why Patient 2’s results weren’t quite as impressive as patient 1’s, Dr. Markmann replied “I think what’s important is that both patients did great. And since this was a half-dose, we might have expected that the outcome was going to be more like patient 2 rather than patient 1. So, I think we’re just going to have to [study this in] more patients to understand where it falls.” 

Although patient 1 experienced a cluster of six severe hypoglycemic events early in the posttransplant period, he had no further events after day 35. Patient 2 had no severe hypoglycemic events.

Other safety events were generally consistent with that seen with the immunosuppressive regimen in the perioperative period. Patient 1 had a “mild and self-limited” rise in liver function test and also experienced two severe adverse events: A rash from the immune suppression that resolved spontaneously, and dehydration requiring hospitalization on day 186. Patient 2’s adverse events were all mild to moderate, most commonly headache and hypomagnesemia and not related to VX-880.

Immunosuppression: Work is ongoing

The immunosuppression regimen used comprises a depletion of lymphocytes at induction, followed by a maintenance regimen of two standard agents used in kidney transplant patients and found to be well tolerated, Dr. Markmann said.

Still, the risk of immunosuppression generally outweighs the potential benefit for most people with type 1 diabetes who are managing reasonably well with insulin treatment.

“This is part one of a two-part problem. One is to have a reliable, consistent, effective cell therapy. The second is to develop an approach that doesn’t require immunosuppression. ... But if we had a way of transplanting the cells without the need for immunosuppression, then it could be really widely available. That’s an opportunity for the future since these cells can be made in unlimited quantities,” Dr. Markmann commented during the press briefing.

Asked for his thoughts about the immunosuppression aspect, Dr. Pragnell told this news organization: “Immune suppression is a concern, but I feel that this is just the start of so much research in this area. They’re going to take this step by step. This is just the start. My understanding is they have additional strategies around immune suppression, and in the future they might not even need immunosuppression. But even at this stage right now, it’s amazing.”

He added: “The ‘artificial pancreas’ is a huge step forward, but it’s just a bridge to a cure, whereas if they’re able to show safety and efficacy, this is potentially a cure. ... I’m very excited about it.”

Dr. Markmann serves on advisory boards for iTolerance, eGenesis, and QihanBio. He is a consultant to Vertex Pharmaceuticals. Dr. Pragnell is an ADA employee and has no further disclosures.

Women are not being warned that anesthetic may reduce birth pill efficacy

Article Type
Changed

The effectiveness of hormonal contraceptives, including the pill and mini-pill, may be compromised by sugammadex, a drug widely used in anesthesia for reversing neuromuscular blockade induced by rocuronium or vecuronium.

Yet women are not routinely informed that the drug may make their contraception less effective, delegates at Euroanaesthesia, the annual meeting of the European Society of Anaesthesiology and Intensive Care in Milan were told.

New research presented at the meeting supports the authors’ experience that “robust methods for identifying at-risk patients and informing them of the associated risk of contraceptive failures is not common practice across anesthetic departments within the United Kingdom, and likely further afield.”

This is according to a survey of almost 150 anesthetic professionals, including consultants, junior doctors, and physician assistants, working at University College London Hospitals NHS Foundation Trust.

Dr. Neha Passi, Dr. Matt Oliver, and colleagues at the trust’s department of anesthesiology sent out a seven-question survey to their 150 colleagues and received 82 responses, 94% of which claimed awareness of the risk of contraceptive failure with sugammadex. However, 70% of the respondents admitted that they do not routinely discuss this with patients who have received the drug.
 

Risk with all forms of hormonal contraceptive

Yet current guidance is to inform women of child-bearing age that they have received the drug and, because of increased risk of contraceptive failure, advise those taking oral hormonal contraceptives to follow the missed pill advice in the leaflet that comes with their contraceptives. It also counsels that clinicians should advise women using other types of hormonal contraceptive to use an additional nonhormonal means of contraception for 7 days.

The study authors also carried out a retrospective audit of sugammadex use in the trust and reported that during the 6 weeks covered by the audit, 234 patients were administered sugammadex of whom 65 (28%) were women of childbearing age. Of these, 17 had a medical history that meant they weren’t at risk of pregnancy, but the other 48 should have received advice on the risks of contraceptive failure – however there was no record in the medical notes of such advice having been given for any of the at-risk 48 women.

While sugammadex is the only anesthetic drug known to have this effect, it is recognized to interact with progesterone and so may reduce the effectiveness of hormonal contraceptives, including the progesterone-only pill, combined pill, vaginal rings, implants, and intrauterine devices.

Dr. Passi said: “It is concerning that we are so seldom informing patients of the risk of contraceptive failure following sugammadex use.

“Use of sugammadex is expected to rise as it becomes cheaper in the future, and ensuring that women receiving this medicine are aware it may increase their risk of unwanted pregnancy must be a priority.”

She added: “It is important to note, however, that most patients receiving an anesthetic do not need a muscle relaxant and that sugammadex is one of several drugs available to reverse muscle relaxation.”

Dr. Oliver said: “We only studied one hospital trust but we expect the results to be similar in elsewhere in the U.K.”

In response to their findings, the study’s authors have created patient information leaflets and letters and programmed the trust’s electronic patient record system to identify “at-risk” patients and deliver electronic prompts to the anesthetists caring for them in the perioperative period.

Surgical site infections not increased in immunocompromised patients after Mohs surgery

Article Type
Changed

Patients who are immunocompromised showed no increased risk of surgical site infection when undergoing Mohs micrographic surgery, regardless of whether or not they received antibiotics, suggesting that antibiotic prophylaxis, which is often used for these patients, may not be necessary, according to new research.

The retrospective cohort study found that “immunosuppressed patients had similar infection rates as immunocompetent patients following Mohs micrographic surgery,” first author Tuyet A. Nguyen, MD, of the department of dermatology, Cedars-Sinai Medical Center, Los Angeles, told this news organization.

“Therefore, antibiotic prescribing patterns should not change simply due to immunosuppression. Furthermore, immunosuppressed patients appear to respond well to antibiotics and recover similarly to immunocompetent patients,” she said.

The study was presented at the annual meeting of the American College of Mohs Surgery.

Mohs surgery is increasingly being performed for patients who are immunosuppressed because of the higher incidence of skin cancer in this group of patients and their higher risk of more aggressive skin cancers.

Overall, the rate of surgical site infections following Mohs surgery generally ranges from 0.5% to 2.4%. However, research is lacking on the risk among patients who are immunosuppressed and on how effective the use of prophylactic antibiotics is for these patients.

For the retrospective study, Dr. Nguyen and her colleagues evaluated data on 5,886 patients who underwent Mohs surgery at Cedars-Sinai between October 2014 and August 2021. Among these patients, 741 (12.6%) were immunocompromised.

Causes of immunosuppression in the cohort included the following: immunosuppression after transplant surgery; having HIVchronic myeloid leukemiamultiple myeloma, or other hematogenous forms of immunosuppression; or immunosuppression related to other conditions, such as chronic inflammatory diseases.



Overall, postprocedural infections occurred in 1.6% (95) of patients, a rate that mirrors that of the general population, Dr. Nguyen noted. No significant differences in surgical site infection rates were observed between immunocompromised patients (2.1%, n = 15) and those who were immunocompetent (1.6%, n = 80; P = .30).

Importantly, among those who were immunocompromised, the rates of infection were not significantly different between those who did receive antibiotics (3.0%, n = 8) and those who did not receive antibiotics (1.5%, n = 7; P = .19).

The lack of a difference in surgical site infection rates among those who did and those who did not receive antibiotics extended to the entire study population (2.0% vs. 1.4%; P = .12).

The study cohort mainly comprised immunosuppressed transplant patients, notably, heart, lung, and kidney transplant patients. However, “even in this population, we did not see a higher rate of infection,” senior author Nima M. Gharavi, MD, PhD, director of dermatologic surgery and Mohs micrographic surgery and associate professor of medicine and pathology and laboratory medicine at Cedars-Sinai Medical Center, said in an interview.

Yet the risk of infection among those patients has been shown to be high and of consequence. Data indicate that infections account for 13%-16% of deaths among kidney and heart transplant patients and up to 21% of deaths among lung transplant patients. The rate of mortality appears to parallel the level of immunosuppression, Dr. Nguyen explained.

Furthermore, up to 25% of patients who undergo heart and lung transplantation develop bacteremia.

In terms of why worse infections or bacteremia surgeries may not occur in association with Mohs, Dr. Nguyen speculated that, as opposed to other surgeries, those involving the skin may benefit from unique defense mechanisms.

“The skin is a complex system in its defense against foreign pathogens and infectious agents,” she explained during her presentation. “There is the physical barrier, the antimicrobial peptides, and an adaptive as well as innate immune response.”

“In immunosuppressed patients, with the decrease in adaptive immunity, it’s possible this loss is less important because the skin has such a robust immune system in general.”

In her presentation, Dr. Nguyen noted that “further studies are necessary to investigate why patients aren’t presenting with greater severity, and we plan to try to investigate whether the unique nature of skin-mediated immunity makes this organ less susceptible to severe or life-threatening infections in patients on immunosuppression.”

Of note, the rate of prophylactic antibiotic prescriptions was no higher for those who were and those who were not immunosuppressed (37.9% vs. 34.1%; P = .14), which Dr. Nguyen said is consistent with recommendations.

“Immunosuppression is not an indication for antibiotic use, and hence, we did not have a higher rate of antibiotics use in this population,” she told this news organization. However, a 2021 ACMS survey found that a high percentage of Mohs surgeons prescribe antibiotics for procedures in which antibiotics are not indicated so as to reduce the risk of infections and that immunosuppression is a common reason for doing so.

The authors have disclosed no relevant financial relationships.

However, a 2021 ACMS survey found that a high percentage of Mohs surgeons prescribe antibiotics for procedures in which antibiotics are not indicated so as to reduce the risk of infections and that immunosuppression is a common reason for doing so.

Bariatric surgery cuts risk of developing and dying from cancer

Article Type
Changed

A new study provides more evidence that the substantial weight loss achieved with bariatric surgery offers long-term protection against cancer.

The study found that adults with obesity who had bariatric surgery had a 32% lower risk of developing cancer and a 48% lower risk of dying from cancer, compared with peers who did not have the surgery.

“The magnitude of the benefit was very large and dose-dependent, with more weight loss associated with greater reduction in cancer risk,” lead investigator Ali Aminian, MD, director of the Bariatric & Metabolic Institute, Cleveland Clinic, told this news organization.

The study was published online in the Journal of the American Medical Association.
 

Best evidence to date

“We know that obesity is strongly linked with different types of cancers, but we didn’t know if losing a significant amount of weight can significantly decrease the risk of cancer,” Dr. Aminian explained.

The SPLENDID study involved 30,318 adults with obesity (median age, 46 years; 77% women; median body mass index, 45 kg/m2). 

The 5,053 patients who underwent Roux-en-Y gastric bypass (66%) or sleeve gastrectomy (34%) were matched (1:5) to 25,265 patients who did not undergo bariatric surgery (nonsurgical control group).

At 10 years, patients who had bariatric surgery had lost 27.5 kg (60 pounds) compared with 2.7 kg (6 pounds) for peers who didn’t have the surgery, a difference of 19.2%. 

During a median follow-up of 6.1 years, 96 patients in the bariatric surgery group and 780 patients in the nonsurgical control group developed an obesity-associated cancer (incidence rate of 3.0 vs. 4.6 events per 1,000 person-years).

At 10 years, the cumulative incidence of obesity-associated cancer was significantly lower in the bariatric surgery group (2.9% vs. 4.9%; absolute risk difference, 2.0%; 95% confidence interval [CI], 1.2%-2.7%; adjusted hazard ratio [HR], 0.68; 95% CI, 0.53-0.87; P = .002).

Most cancer types were less common in the bariatric surgery group. However, a comprehensive analysis of the impact of bariatric surgery on individual cancer types was not possible.

In the fully-adjusted Cox models, the association between bariatric surgery and individual cancer types was significant only for endometrial cancer (adjusted HR, 0.47; 95% CI, 0.27-0.83). 

For the other individual cancers, there was a “trend or signal toward a reduction in their risk after the surgery,” Dr. Aminian said.

He noted that endometrial cancer has the strongest association with obesity, and patients who seek bariatric surgery are typically obese, middle-aged women.

“So, it was not surprising that we had more cases of endometrial cancer than other types of cancer,” he said.

The SPLENDID study also showed a significant reduction in cancer-related mortality at 10 years in patients with vs. without bariatric surgery (0.8% vs. 1.4%; adjusted HR, 0.52; 95% CI, 0.31-0.88; P = .01).

The benefits of bariatric surgery were evident in both women and men, younger and older patients, and Black and White patients, and were similarly observed after both gastric bypass and sleeve gastrectomy.

For the cancer protective effect, patients need to lose at least 20%-25% of their body weight, which is almost impossible with diet alone, Dr. Aminian said.

Obesity is “second only to tobacco” as a preventable cause of cancer in the United States, senior author Steven Nissen, MD, chief academic officer of the Heart, Vascular, and Thoracic Institute at Cleveland Clinic, said in a news release.

“This study provides the best possible evidence on the value of intentional weight loss to reduce cancer risk and mortality,” Dr. Nissen said.
 

 

 

Questions remain

In an accompanying editorial, Anita P. Courcoulas, MD, of the University of Pittsburgh Medical Center, said future studies should look at potential factors that influence the association between bariatric surgery and reduced cancer risk, with an eye toward individualizing treatment and figuring out who will benefit the most.

“It is likely that cancer risk reduction after bariatric surgery varies by sex, age, race and ethnicity, type of bariatric surgery, alcohol and smoking status, cancer site, diabetes status, body mass index, and other factors,” Dr. Courcoulas pointed out.

“In addition, there is a need to understand the specific biological mechanisms of effect responsible for the observed change in cancer risk because these mechanisms have not been clearly investigated and elucidated in humans,” she said.

“If this association is further validated, it would extend the benefits of bariatric surgery to another important area of long-term health and prevention. This additional information could then further guide for whom bariatric surgery is most beneficial,” Dr. Courcoulas concluded.

The study had no specific funding. Dr. Aminian reported receiving grants and speaking honoraria from Medtronic. Dr. Nissen reported receiving grants from Novartis, Eli Lilly, AbbVie, Silence Therapeutics, AstraZeneca, Esperion Therapeutics, Amgen, and Bristol Myers Squibb.

Mohs surgery in the elderly: The dilemma of when to treat

Article Type
Changed

As increasing numbers of patients in their 80s, 90s, and even 100s present for possible Mohs micrographic surgery, surgeons are confronted with deciding when the risks of treatment may outweigh the benefits.

In one of two presentations at the annual meeting of the American College of Mohs Surgery that addressed this topic, Howard W. Rogers, MD, of Advanced Dermatology in Norwich, Conn., said that the crux of the issue is the concern not to undertreat. He noted that reduced access to dermatologic care during the pandemic has provided a stark lesson in the risks of delaying treatment in all age groups. “Mohs surgeons have all seen the consequences of delayed treatment due to the pandemic with enormous, destructive, and sometimes fatal cancers coming to the office in the last year,” he told this news organization.

Dr. Howard W. Rogers

“Pandemic-related treatment delay has caused increased suffering and morbidity for countless skin cancer patients across the U.S.,” he said. “In general, not treating skin cancer and hoping it’s not going to grow or having significant delays in treatment are a recipe for disastrous outcomes.”

That said, active monitoring may be appropriate “for select small cancers that tend to grow slowly in the very elderly,” added Dr. Rogers, the incoming ACMS president. Among the key situations where the benefits of active monitoring may outweigh the risks of surgery are small, slowly growing cancers, when frailty is an issue.

Frailty has been equated to compromised functionality, which can increase the risk of an array of complications, including prolonged wound healing and secondary complications stemming from immobility. The toll those issues can take on patients’ quality of life can be considerable, Dr. Rogers said.

When weighing treatment options with elderly patients, he emphasized that careful consideration should be given to whether the “time needed to benefit from a Mohs procedure is longer than the patient’s life expectancy.” Furthermore, a decision not to treat does not have to be the last word. “We need to have an honest dialogue on the consequences of nontreatment, but part of that should be that just because we don’t treat today, doesn’t mean we can’t treat it tomorrow, if necessary.”

Of note, he added, “more than 100,00 patients have surgery for basal cell carcinoma [BCC] in their last year of life.” And that figure will likely rise exponentially if population projections come to fruition, considering that the population of people over the age of 85 is predicted to increase to nearly 18 million in 2050, from 5.8 million in 2012, Dr. Rogers said.

Until more research emerges on how to best treat this age group, Dr. Rogers noted that experts recommend that for elderly patients, “treatment should be individualized with consideration of active monitoring of primary BCC that is not in the H-zone, asymptomatic, smaller than 1 cm, with treatment initiated if there is substantial growth or symptoms.” Ultimately, he urged surgeons to “be sensitive and treat our patients like ourselves or our family members.”
 

 

 

When appropriate – Mohs is safe in the very elderly

Taking on the issue in a separate presentation, Deborah MacFarlane, MD, professor of dermatology and head and neck surgery at MD Anderson Cancer Center, Houston, said that for skin cancer cases that warrant treatment, clinicians should not let age alone stand in the way of Mohs surgery.

Dr. Deborah MacFarlane

The evidence of its safety in the elderly dates back to a paper published in 1997 that Dr. MacFarlane coauthored, describing Mohs surgery of BCCs, squamous cell cancers (SCCs), and melanomas among 115 patients aged 90 and older (average, 92.4 years) who had an average of 1.9 comorbid medical conditions, and were taking an average of 2.3 medications. “Overall, we had just one complication among the patients,” she said.

In a subsequent paper, Dr. MacFarlane and her colleagues found that age at the time of Mohs surgery, even in older patients, was unrelated to survival, stage of cancer, or the type of repair. “We have concluded that this rapidly growing segment of the population can undergo Mohs surgery and should not be relegated to less effective treatment out of fear of its affecting their survival,” Dr. MacFarlane said.

She agreed with the concern about frailty and hence functionality, which may need to be factored in when making a decision to perform Mohs surgery. “I think this is something we do intuitively anyway,” she added. “We’re going to offer Mohs to someone who we think will survive and who is in relatively good health,” Dr. MacFarlane noted.

The point is illustrated in a new multicenter study of 1,181 patients at 22 U.S. sites, aged 85 years and older with nonmelanoma skin cancer referred for Mohs surgery. In the study, published in JAMA Dermatology after the ACMS meeting, patients who had Mohs surgery were almost four times more likely to have high functional status (P < .001) and were more likely to have facial tumors (P < .001), compared with those who had an alternate surgery.

The main reasons provided by the surgeons for opting to treat with Mohs included a patient’s desire for treatment with a high cure rate (66%), good/excellent patient functional status for age (57%), and a high risk associated with the tumor based on histology (40%), noted Dr. MacFarlane, one of the authors.



She reiterated the point raised by Dr. Rogers that “this is something we’re going to increasingly face,” noting that people over 85 represent the fastest growing segment of the population. “I have more patients over the age of 100 than I’ve ever had before,” she said.

Nevertheless, her own experience with elderly patients speaks to the safety of Mohs surgery in this population: Dr. MacFarlane reported a review of her practice’s records of 171 patients aged 85 years and older between May 2016 and May 2022, who received 414 separate procedures, without a single complication.

Sharing many of Dr. Rogers’ concerns about using caution in at-risk patients, Dr. MacFarlane offered recommendations for the optimal treatment of elderly patients receiving Mohs, including handling tissue delicately, and “keep undermining to a minimum.” She noted that intermediate closures and full thickness skin grafts are ideal closures for the elderly, while flaps may be performed in selected robust skin. It is also important to involve caretakers from the onset, talk and listen to patients – and play their choice of music during treatment, she said.

Commenting on the debate, comoderator Nahid Y. Vidal, MD, of the department of dermatology, Mayo Clinic, Rochester, Minn., noted that the expanding older population is accompanied by increases in skin cancer, in addition to more immunosenescence that is related to development of infections, autoimmune disease, and malignant tumors.

Dr. Nahid Y. Vidal

“In our academic practice, as with both the reference speakers, we do frequently see elderly, and not uncommonly the super-elderly,” she told this news organization. “The take-home point for me is to treat your whole patient, not just the tumor,” considering social factors, frailty/spry factor, and preferences, “and to do the humanistic thing, while also remaining evidence based,” she said.

“Don’t assume that increased age translates to morbidity, worse outcomes, or futility of treatment,” she added. “Chances are, if [a patient] made it to 90 years old with only a few medications and few medical problems, they may make it to 100, so why put the patient at risk for metastasis and death from a treatable/curable skin cancer,” in the case of SCC, she said.

“By the same token, why not perform more conservative treatments such as ED&C [electrodesiccation and curettage] for very low-risk skin cancers in low-risk locations, such as a superficial basal cell carcinoma on the trunk?” Overall, instead of trying to determine how long a super-elderly individual will live, Dr. Vidal said that “it’s better to educate the patient, engage in a discussion about goals of care, and to make few assumptions.”

Dr. Rogers, Dr. MacFarlane, and Dr. Vidal report no disclosures.

He noted that reduced access to dermatologic care during the pandemic has provided a stark lesson in the risks of delaying treatment in all age groups. “Mohs surgeons have all seen the consequences of delayed treatment due to the pandemic with enormous, destructive, and sometimes fatal cancers coming to the office in the last year,” he told this news organization.

Dr. Howard W. Rogers

“Pandemic-related treatment delay has caused increased suffering and morbidity for countless skin cancer patients across the U.S.,” he said. “In general, not treating skin cancer and hoping it’s not going to grow or having significant delays in treatment are a recipe for disastrous outcomes.”

That said, active monitoring may be appropriate “for select small cancers that tend to grow slowly in the very elderly,” added Dr. Rogers, the incoming ACMS president. Among the key situations where the benefits of active monitoring may outweigh the risks of surgery are small, slowly growing cancers, when frailty is an issue.

Frailty has been equated to compromised functionality, which can increase the risk of an array of complications, including prolonged wound healing and secondary complications stemming from immobility. The toll those issues can take on patients’ quality of life can be considerable, Dr. Rogers said.

When weighing treatment options with elderly patients, he emphasized that careful consideration should be given to whether the “time needed to benefit from a Mohs procedure is longer than the patient’s life expectancy.” Furthermore, a decision not to treat does not have to be the last word. “We need to have an honest dialogue on the consequences of nontreatment, but part of that should be that just because we don’t treat today, doesn’t mean we can’t treat it tomorrow, if necessary.”

Of note, he added, “more than 100,00 patients have surgery for basal cell carcinoma [BCC] in their last year of life.” And that figure will likely rise exponentially if population projections come to fruition, considering that the population of people over the age of 85 is predicted to increase to nearly 18 million in 2050, from 5.8 million in 2012, Dr. Rogers said.

Until more research emerges on how to best treat this age group, Dr. Rogers noted that experts recommend that for elderly patients, “treatment should be individualized with consideration of active monitoring of primary BCC that is not in the H-zone, asymptomatic, smaller than 1 cm, with treatment initiated if there is substantial growth or symptoms.” Ultimately, he urged surgeons to “be sensitive and treat our patients like ourselves or our family members.”
 

 

 

When appropriate – Mohs is safe in the very elderly

Taking on the issue in a separate presentation, Deborah MacFarlane, MD, professor of dermatology and head and neck surgery at MD Anderson Cancer Center, Houston, said that for skin cancer cases that warrant treatment, clinicians should not let age alone stand in the way of Mohs surgery.

Dr. Deborah MacFarlane

The evidence of its safety in the elderly dates back to a paper published in 1997 that Dr. MacFarlane coauthored, describing Mohs surgery of BCCs, squamous cell cancers (SCCs), and melanomas among 115 patients aged 90 and older (average, 92.4 years) who had an average of 1.9 comorbid medical conditions, and were taking an average of 2.3 medications. “Overall, we had just one complication among the patients,” she said.

In a subsequent paper, Dr. MacFarlane and her colleagues found that age at the time of Mohs surgery, even in older patients, was unrelated to survival, stage of cancer, or the type of repair. “We have concluded that this rapidly growing segment of the population can undergo Mohs surgery and should not be relegated to less effective treatment out of fear of its affecting their survival,” Dr. MacFarlane said.

She agreed with the concern about frailty and hence functionality, which may need to be factored in when making a decision to perform Mohs surgery. “I think this is something we do intuitively anyway,” she added. “We’re going to offer Mohs to someone who we think will survive and who is in relatively good health,” Dr. MacFarlane noted.

The point is illustrated in a new multicenter study of 1,181 patients at 22 U.S. sites, aged 85 years and older with nonmelanoma skin cancer referred for Mohs surgery. In the study, published in JAMA Dermatology after the ACMS meeting, patients who had Mohs surgery were almost four times more likely to have high functional status (P < .001) and were more likely to have facial tumors (P < .001), compared with those who had an alternate surgery.

The main reasons provided by the surgeons for opting to treat with Mohs included a patient’s desire for treatment with a high cure rate (66%), good/excellent patient functional status for age (57%), and a high risk associated with the tumor based on histology (40%), noted Dr. MacFarlane, one of the authors.



She reiterated the point raised by Dr. Rogers that “this is something we’re going to increasingly face,” noting that people over 85 represent the fastest growing segment of the population. “I have more patients over the age of 100 than I’ve ever had before,” she said.

Nevertheless, her own experience with elderly patients speaks to the safety of Mohs surgery in this population: Dr. MacFarlane reported a review of her practice’s records of 171 patients aged 85 years and older between May 2016 and May 2022, who received 414 separate procedures, without a single complication.

Sharing many of Dr. Rogers’ concerns about using caution in at-risk patients, Dr. MacFarlane offered recommendations for the optimal treatment of elderly patients receiving Mohs, including handling tissue delicately, and “keep undermining to a minimum.” She noted that intermediate closures and full thickness skin grafts are ideal closures for the elderly, while flaps may be performed in selected robust skin. It is also important to involve caretakers from the onset, talk and listen to patients – and play their choice of music during treatment, she said.

Commenting on the debate, comoderator Nahid Y. Vidal, MD, of the department of dermatology, Mayo Clinic, Rochester, Minn., noted that the expanding older population is accompanied by increases in skin cancer, in addition to more immunosenescence that is related to development of infections, autoimmune disease, and malignant tumors.

Dr. Nahid Y. Vidal

“In our academic practice, as with both the reference speakers, we do frequently see elderly, and not uncommonly the super-elderly,” she told this news organization. “The take-home point for me is to treat your whole patient, not just the tumor,” considering social factors, frailty/spry factor, and preferences, “and to do the humanistic thing, while also remaining evidence based,” she said.

“Don’t assume that increased age translates to morbidity, worse outcomes, or futility of treatment,” she added. “Chances are, if [a patient] made it to 90 years old with only a few medications and few medical problems, they may make it to 100, so why put the patient at risk for metastasis and death from a treatable/curable skin cancer,” in the case of SCC, she said.

“By the same token, why not perform more conservative treatments such as ED&C [electrodesiccation and curettage] for very low-risk skin cancers in low-risk locations, such as a superficial basal cell carcinoma on the trunk?” Overall, instead of trying to determine how long a super-elderly individual will live, Dr. Vidal said that “it’s better to educate the patient, engage in a discussion about goals of care, and to make few assumptions.”

Dr. Rogers, Dr. MacFarlane, and Dr. Vidal report no disclosures.

Surgeons, who see it up close, offer ways to stop gun violence

Article Type
Changed

Trauma surgeons are in the tough position of seeing victims just after gun violence across the United States, and they have some advice.

Their strategies can work regardless of where you stand on the Second Amendment of the Constitution, said Patricia Turner, MD. “Our proposals are embraced by both gun owners and non–gun owners alike, and we are unique in that regard.”

These “implementable solutions” could prevent the next massacre, Dr. Turner, executive director of the American College of Surgeons, said during a news briefing the group sponsored on June 2.

“Our future – indeed all of our futures – depend on our ability to find durable, actionable steps that we can implement tomorrow to save lives,” she said.
 

Firsthand perspective

“Sadly I’m here today as a trauma surgeon who has cared for two of the largest mass shootings in modern U.S. history,” said Ronald Stewart, MD, chair of the department of surgery at University Hospital in San Antonio, Texas.

Dr. Stewart treated victims of the 2017 Sutherland Springs First Baptist Church shooting – where 27 people died, including the shooter – and the recent Uvalde school shooting, both in Texas.

“The injuries inflicted by high-velocity weapons used at both of these attacks are horrific. A high-capacity, magazine-fed automatic rifle such as the AR-15 causes extremely destructive tissue wounds,” he said.

One of the group’s proposals is to increase the regulation of high-velocity weapons, including AR-15s.

“These wounds are horribly lethal at close range, and sadly, most victims do not survive long enough to make it to a trauma center,” Dr. Stewart said.

On a positive note, “all of our current [Uvalde] patients are improving, which really brings us joy in this dark time,” he said. “But all of them have a long road to deal with recovery with both the physical and emotional impact of their injuries.”

Jeffrey Kerby, MD, agreed.

“Trauma surgeons see the short-term physical effects of these injuries and watch patients struggle with the long-term impact of these wounds,” said Dr. Kerby, director of trauma and acute care surgery at the University of Alabama at Birmingham.
 

Surgeons feel ‘profound impact’ of shootings

“Firearm violence has a profound impact on surgeons, and we are the undisputed subject matter experts in treating the tragic results,” said Patrick Bailey, MD, medical director for advocacy at the American College of Surgeons.

“This impacts surgeons as well,” said Dr. Kerby, chair of the Committee on Trauma for the surgeons’ group. “We are human, and we can’t help but share in the grief, the pain, and the suffering that our patients endure.

“As a pediatric surgeon ... I have too often witnessed the impact of firearm violence, and obviously, the devastation extends beyond the victims to their families,” he said. “To put it succinctly, in our culture, parents are not supposed to be put in a position of burying their children.”
 

A public health crisis

“It’s important to recognize that we’ve been talking about a public health approach,” said Eileen Bulger, MD, acting chief of the trauma division at the University of Washington in Seattle. That strategy is important for engaging both firearm owners and communities that have a higher risk for firearm violence, she said.

A committee of the American College of Surgeons developed specific recommendations in 2018, which are still valid today. The group brought together surgeons from across the U.S. including “passionate firearm owners and experts in firearm safety,” Dr. Bulger said.

The committee, for example, agreed on 10 specific recommendations “that we believe are bipartisan and could have an immediate impact in saving lives.”

“I’m a lifelong gun owner,” Dr. Bailey said, emphasizing that the team’s process included participation and perspective from other surgeons “who, like me, are also gun owners, but gun owners who also seek to reduce the impact of firearm violence in our country.”

The recommendations address these areas:

  • Gun ownership
  • Firearm registration
  • Licensure
  • Education and training
  • Ownership responsibilities
  • Mandatory reporting and risk reduction
  • Safety innovation and technology
  • Research
  • The culture of violence
  • Social isolation and mental health

For example, “we currently have certain classes of weapons with significant offensive capability,” Dr. Bulger said, “that are appropriately restricted and regulated under the National Firearms Act as Class 3 weapons.”

This group includes fully automatic machine guns, explosive devices, and short-barrel shotguns.

“We recommend a formal reassessment of the firearms designated within each of these national firearms classifications,” Dr. Bulger said.

For example, high-capacity, magazine-fed semiautomatic rifles, such as the AR-15, should be considered for reclassification as NFA Class 3 firearms, or they should get a new designation with tighter regulation.

The ACS endorses formal firearm safety training for all new gun owners. Also, owners who do not provide reasonably safe firearm storage should be held responsible for events related to the discharge of their firearms, Dr. Bulger said. And people who are deemed an imminent threat to themselves or others through firearm ownership should be temporarily or permanently restricted, with due process.
 

Research and reporting reforms

The ACS is also calling for research on firearm injuries and firearm injury prevention to be federally funded, Dr. Bulger said. The research should be done in a nonpartisan manner, she said.

“We have concerns that the manner and tone in which information is released to the public may lead to copycat mass killers,” she said. “The ACS recommends that law enforcement officials and the press take steps to eliminate the notoriety of the shooter, for example.”

Dr. Bulger also addressed the mental health angle. “We encourage recognition of mental health warning signs and social isolation by teachers, counselors, peers, and parents.” When identified, immediate referral to professionals is needed.

In addition to these recommendations, another team from the American College of Surgeons has published an overview of ways to address the inequities that contribute to violence. “We advocate for federal funding to support the development of hospital-based and community programs for violence intervention and prevention,” Dr. Bulger said.

Dr. Bailey said that as a gun owner himself, he thinks other gun owners would support these recommendations.

“I do not believe that the steps recommended ... pose undue burden on the rights of individual gun owners,” he said.
 

The time is now

Most firearm injuries are not from mass shooting events, Dr. Kerby said.

“My own trauma center has seen a 40% increase in the number of firearm injuries just in the last 2 years,” he added, “and these numbers continue to grow.”

High rates of med student burnout during COVID

Article Type
Changed

NEW ORLEANS – The COVID-19 pandemic has challenged the academic and psychological stability of medical students, leading to high rates of burnout.

Researchers surveyed 613 medical students representing all years of a medical program during the last week of the Spring semester of 2021.

Based on the Maslach Burnout Inventory-Student Survey (MBI-SS), more than half (54%) of the students had symptoms of burnout.

Eighty percent of students scored high on emotional exhaustion, 57% scored high on cynicism, and 36% scored low on academic effectiveness.

Compared with male medical students, female medical students were more apt to exhibit signs of burnout (60% vs. 44%), emotional exhaustion (80% vs. 73%), and cynicism (62% vs. 49%).

After adjusting for associated factors, female medical students were significantly more likely to suffer from burnout than male students (odds ratio, 1.90; 95% confidence interval, 1.34-2.70; P < .001).

Smoking was also linked to higher likelihood of burnout among medical students (OR, 2.12; 95% CI, 1.18-3.81; P < .05). The death of a family member from COVID-19 also put medical students at heightened risk for burnout (OR, 1.60; 95% CI, 1.08-2.36; P < .05).

The survey results were presented at the American Psychiatric Association (APA) Annual Meeting.

The findings point to the need to study burnout prevalence in universities and develop strategies to promote the mental health of future physicians, presenter Sofia Jezzini-Martínez, fourth-year medical student, Autonomous University of Nuevo Leon, Monterrey, Mexico, wrote in her conference abstract.

In related research presented at the APA meeting, researchers surveyed second-, third-, and fourth-year medical students from California during the pandemic.

Roughly 80% exhibited symptoms of anxiety and 68% exhibited depressive symptoms, of whom about 18% also reported having thoughts of suicide.

Yet only about half of the medical students exhibiting anxiety or depressive symptoms sought help from a mental health professional, and 20% reported using substances to cope with stress.

“Given that the pandemic is ongoing, we hope to draw attention to mental health needs of medical students and influence medical schools to direct appropriate and timely resources to this group,” presenter Sarthak Angal, MD, psychiatry resident, Kaiser Permanente San Jose Medical Center, California, wrote in his conference abstract.
 

Managing expectations

Weighing in on medical student burnout, Ihuoma Njoku, MD, department of psychiatry and neurobehavioral sciences, University of Virginia, Charlottesville, noted that, “particularly for women in multiple fields, including medicine, there’s a lot of burden placed on them.”

“Women are pulled in a lot of different directions and have increased demands, which may help explain their higher rate of burnout,” Dr. Njoku commented.

She noted that these surveys were conducted during the COVID-19 pandemic, “a period when students’ education experience was a lot different than what they expected and maybe what they wanted.”

Dr. Njoku noted that the challenges of the pandemic are particularly hard on fourth-year medical students.

“A big part of fourth year is applying to residency, and many were doing virtual interviews for residency. That makes it hard to really get an appreciation of the place you will spend the next three to eight years of your life,” she told this news organization.

NEW ORLEANS – The COVID-19 pandemic has challenged the academic and psychological stability of medical students, leading to high rates of burnout.

Dr. Njoku noted that the challenges of the pandemic are particularly hard on fourth-year medical students.

“A big part of fourth year is applying to residency, and many were doing virtual interviews for residency. That makes it hard to really get an appreciation of the place you will spend the next three to eight years of your life,” she told this news organization.

NEW ORLEANS – The COVID-19 pandemic has challenged the academic and psychological stability of medical students, leading to high rates of burnout.

Researchers surveyed 613 medical students representing all years of a medical program during the last week of the Spring semester of 2021.

Based on the Maslach Burnout Inventory-Student Survey (MBI-SS), more than half (54%) of the students had symptoms of burnout.

Eighty percent of students scored high on emotional exhaustion, 57% scored high on cynicism, and 36% scored low on academic effectiveness.

Compared with male medical students, female medical students were more apt to exhibit signs of burnout (60% vs. 44%), emotional exhaustion (80% vs. 73%), and cynicism (62% vs. 49%).

After adjusting for associated factors, female medical students were significantly more likely to suffer from burnout than male students (odds ratio, 1.90; 95% confidence interval, 1.34-2.70; P < .001).

Smoking was also linked to higher likelihood of burnout among medical students (OR, 2.12; 95% CI, 1.18-3.81; P < .05). The death of a family member from COVID-19 also put medical students at heightened risk for burnout (OR, 1.60; 95% CI, 1.08-2.36; P < .05).

The survey results were presented at the American Psychiatric Association (APA) Annual Meeting.

The findings point to the need to study burnout prevalence in universities and develop strategies to promote the mental health of future physicians, presenter Sofia Jezzini-Martínez, fourth-year medical student, Autonomous University of Nuevo Leon, Monterrey, Mexico, wrote in her conference abstract.

In related research presented at the APA meeting, researchers surveyed second-, third-, and fourth-year medical students from California during the pandemic.

Roughly 80% exhibited symptoms of anxiety and 68% exhibited depressive symptoms, of whom about 18% also reported having thoughts of suicide.

Yet only about half of the medical students exhibiting anxiety or depressive symptoms sought help from a mental health professional, and 20% reported using substances to cope with stress.

“Given that the pandemic is ongoing, we hope to draw attention to mental health needs of medical students and influence medical schools to direct appropriate and timely resources to this group,” presenter Sarthak Angal, MD, psychiatry resident, Kaiser Permanente San Jose Medical Center, California, wrote in his conference abstract.
 

Managing expectations

Weighing in on medical student burnout, Ihuoma Njoku, MD, department of psychiatry and neurobehavioral sciences, University of Virginia, Charlottesville, noted that, “particularly for women in multiple fields, including medicine, there’s a lot of burden placed on them.”

“Women are pulled in a lot of different directions and have increased demands, which may help explain their higher rate of burnout,” Dr. Njoku commented.

She noted that these surveys were conducted during the COVID-19 pandemic, “a period when students’ education experience was a lot different than what they expected and maybe what they wanted.”

Liver transplanted after 3 days outside body

Article Type
Changed

A poor-quality human liver, rejected by all transplant centers, was treated outside the body for 3 days using a perfusion machine that simulated some functions of the human body and has been successfully transplanted into a patient with advanced cirrhosis.

The 62-year-old patient rapidly returned to normal quality of life and at the 1-year follow-up had no signs of liver damage, such as rejection or bile duct injury, according to the report published in Nature Biotechnology.

The study team was led by Pierre-Alain Clavien, MD, PhD, with the department of surgery and transplantation, Swiss Hepato-Pancreato-Biliary and Transplant Center, University Hospital Zürich, and the Wyss Zürich Translational Center, ETH Zürich and University of Zürich.
 

Expanding the viability window

Livers for transplant are routinely preserved in a static cold solution and implanted within a few hours. Most centers limit the time in the cold solution to 12 hours as the organ’s viability drops quickly after that time.

“This inaugural clinical success opens new horizons in clinical research and promises an extended time window of up to 10 days for assessment of viability of donor organs as well as converting an urgent and highly demanding surgery into an elective procedure,” the authors wrote.

The Liver4Life team, made up of physicians, engineers, and biochemists, developed the complex perfusion machine. Features of the machine, which mimics human body functions, include automated remote control of all key parameters. A pump mimics the heart, an oxygenator replaces the lungs, and a dialysis unit performs as kidneys would. Hormone and nutrient infusions take over the work of the intestines and pancreas. The machine also moves the liver to the rhythm of simulated breathing.

The team had to solve factors that limit viability for any solid organ outside the body over a few hours including hemolysis, hemodynamic stability, glucose control, pathologic glycogen deposition and perfusate quality and dilution.

Additionally, because the organ would be under machine perfusion for several days, the scientists also had to address pressure necrosis.
 

History behind the procedure

The process started in 2015 with the support of the Wyss Zürich Translational Center, with the goal of long-term ex situ machine perfusion of injured liver grafts.

As part of the agreement from the Swiss regulatory authority (the Federal Office of Public Health) the process would be used only if the organ was rejected by all transplant centers, the recipient had no other options for a donor liver, and if the organ met a rigorous bar for viability.

On May 19, 2021, the team was offered a liver graft from a 29-year-old female donor who had an invasive abdominal desmoid fibromatosis associated with chronic intra-abdominal abscesses and recurrent sepsis episodes from multiresistant bacteria. The donor needed long-term multiple medications and parenteral nutrition. Additionally, there was a 4-cm tumor in segment 1 of the liver.

The liver was refused by all other centers, “primarily because it required diagnostic workup of the liver lesion, which was not immediately possible, and because of the ongoing sepsis in the donor with multiresistant microorganisms,” the authors wrote.

The team removed the liver, and the graft was connected to the Wyss perfusion device for normothermic (37 °C) ex situ perfusion after 4 hours of cold preservation.

A 62-year-old male potential recipient on the official national transplant list, had earlier agreed to be considered for receiving a graft preserved ex situ in the Wyss machine.

The patient was fully informed about the process and the presence of a benign lesion in the graft and accepted the transplantation procedure. The patient had advanced cirrhosis, severe portal hypertension, and multiple and recurrent hepatocellular carcinoma (HCC).
 

 

 

Recipient had ‘near-zero’ chance to get a liver in time

The authors wrote that the patient had “a near-zero chance to receive a graft in time.”

For patients with HCC in Switzerland, the wait for liver transplant is longer than a year and no living-donor options were available.

The transplant operation took 5 hours and 26 minutes and blood loss was limited (600 mL). No transfusion was required. The patient was extubated in the operating room, transferred to the ICU, and discharged 12 days later.

Because a biopsy showed no detectable liver injury or rejection, and based on previous evidence of lower immunogenicity in perfused livers and kidneys, the researchers chose a reduced immunosuppressive regimen with quickly tapering steroids. The steroids were completely discontinued 6 weeks after surgery.

The authors wrote: “In our experience, the absence or very low degree of reperfusion injury seen in our transplant is observed only in living donation, where ‘close-to-perfect’ livers from healthy young donors are transplanted immediately as both donors and recipient are operated in parallel.”

In a press release, the team said the next step is to assess the procedure in other patients in a multicenter study.

Dr. Clavien and several coauthors affiliated with ETH (the Swiss Federal Institute of Technology in Zürich) and the University of Zürich have applied for patents on this new perfusion technology. No other authors have any competing interest.

Today’s medical oxymoron: Healthy overconfidence

Article Type
Changed

 

Doctor, doctor, gimme the news. I got a bad case of knowing better than you

Stop us if you’ve heard this before. One of your parents (let’s be honest, probably your ornery father) refuses to go to the doctor. You tell him it’s for the best, but in his words, “Doctors don’t know nothin’. I’m fine.” How many TV shows with grumpy fathers feature this exact plot in an episode as the frustrated child attempts increasingly convoluted traps to encourage the stubborn parent to get himself to the doctor?

As is so often the case, wacky sitcoms reflect reality, according to a new study from the Journal of the Economics of Aging. In a massive survey of 80,000 Europeans aged 50 years and older, the researchers found that individuals who were overconfident and rated their health as better than it actually was visited their doctor 17% less often than did those who correctly judge their own health. Fewer medical visits leaves them more vulnerable to chronic disease, since they’re not getting the preventive care they need to catch illnesses early.

Perhaps unsurprisingly, the inverse is also true: People who underestimate their health status visit the doctor 21% more often. On the one hand, regular visits to the doctor are a good thing, as is awareness of how healthy one really is. On the other hand, though, extra visits cost money and time, especially relevant in an aging society with high public health costs.

Nobody likes visiting the doctor, but it is kind of important, especially as we age and our bodies start to let us down. Confidence is fine, but don’t be overly confident. And if you do go, don’t be like a certain former president of the United States. Don’t pay a sycophant to look in your general direction and then declare that you are in very good (great!) condition on Twitter. That’s not how medicine is meant to work.
 

Your liver stays toddler age

Rapid cell regeneration might seem like something straight out of a sci-fi novel, but it happens to your liver all the time. So much so that the human liver is never a day over 3 years old.

How’s that possible? The liver deals with a lot of toxic substances in its job as the Brita filter of the human body, so it has a unique capacity among organs to regenerate itself after damage.

Dr. Olaf Bergmann and his team at Technical University Dresden’s (Germany) Center for Regenerative Therapies used retrospective radiocarbon birth dating to determine the age of the livers of a group of people who died at the ages of 20-84 years. The results were the same regardless of age.

This information could be a complete game changer for understanding cell regeneration. It’s important in determining cancer cell formation in the liver but also if new heart muscle cells can be generated in people with cardiovascular disease, which the researchers are looking into.

So sure, your liver may be totally capable of filtering those drinks at happy hour, but as old as it is, a juice box might be more appropriate.
 

 

 

To bee, or not to bee? That is the vacation

Sleeping is pretty important for humans, no doubt about that, so anything that improves sleep is worth considering, right? But how far would you go for a good night’s sleep? Would you be willing to travel to Italy to experience the ultimate white-noise generator?

Airbnb

For more on this exciting, yet also sleep-inducing, news story, let’s go to the village of Grottole in southern Italy, where we meet bee keeper and Airbnb host Rocco Filomeno. ”This is the first place in the world where you can sleep immersed in the distinctive sound and aroma of the bees, experiencing ‘bee-therapy’ in the most authentic and natural way,” he said in a written statement for Airbnb.

Mr. Filomeno worked with local NGO Wonder Grottole and a self-build specialist to take the next step in tiny-house evolution. The resulting structure cost just $17,000 – crowdfunded, of course, and built by 25 local bee-lievers (aka volunteers) – and consists of a single room surrounded by nine apiaries, which contain a combined total of 1 million working bees. It is now available to book on Airbnb, and guests “will receive their first lesson on bees and how to live with them,” Airbnb said.

The immersion in bee sound/scent is fully realized through the building’s most prominent interior feature, a screened box in the ceiling with a working hive that allows guests to see the bees and fall asleep to the “gently humming sound,” Airbnb explained. The sound from the hive is said to have a soothing effect that “acts as salve to day-to-day stressors,” according to the BBC.

This is just the start of a trend and we want in on it. Should our tiny house feature the sights/smells/sounds of angry rattlesnakes or a swarm of locusts?
 

Joysticks can make the world a better place

Someday, it might be possible for surgeons to treat a stroke or aneurysm during the “golden hour,” even if they’re not in the same hospital as the patient. MIT engineers have created a robotic system that can be controlled remotely with a modified joystick, so the patient can go to a closer, smaller hospital and be treated by a surgeon at a larger facility through live imaging.

Xuanhe Zhao et al/MIT

Endovascular surgery seems difficult enough with the patient and doctor in the same hospital, “but having a robot twist with the same level of sophistication [as a surgeon] is challenging,” Yoonho Kim, lead author of a study in Science Robotics, said in a written statement. “Our system is based on a fundamentally different mechanism.”

It involves “a medical-grade robotic arm with a magnet attached to its wrist. With a joystick and live imaging, an operator can adjust the magnet’s orientation and manipulate the arm to guide a soft and thin magnetic wire through arteries and vessels,” MIT explained in the statement.

The system was tested using life-like models, and it took each surgeon about an hour of training to learn how to use the new joystick and other equipment. Another perk: No exposure to radiation from x-ray imaging.

If someone you know is obsessed with video games, stop thinking “slacker” and start thinking “neurosurgeon.”

So sure, your liver may be totally capable of filtering those drinks at happy hour, but as old as it is, a juice box might be more appropriate.
 

 

 

To bee, or not to bee? That is the vacation

Sleeping is pretty important for humans, no doubt about that, so anything that improves sleep is worth considering, right? But how far would you go for a good night’s sleep? Would you be willing to travel to Italy to experience the ultimate white-noise generator?

Airbnb

For more on this exciting, yet also sleep-inducing, news story, let’s go to the village of Grottole in southern Italy, where we meet bee keeper and Airbnb host Rocco Filomeno. ”This is the first place in the world where you can sleep immersed in the distinctive sound and aroma of the bees, experiencing ‘bee-therapy’ in the most authentic and natural way,” he said in a written statement for Airbnb.

Mr. Filomeno worked with local NGO Wonder Grottole and a self-build specialist to take the next step in tiny-house evolution. The resulting structure cost just $17,000 – crowdfunded, of course, and built by 25 local bee-lievers (aka volunteers) – and consists of a single room surrounded by nine apiaries, which contain a combined total of 1 million working bees. It is now available to book on Airbnb, and guests “will receive their first lesson on bees and how to live with them,” Airbnb said.

The immersion in bee sound/scent is fully realized through the building’s most prominent interior feature, a screened box in the ceiling with a working hive that allows guests to see the bees and fall asleep to the “gently humming sound,” Airbnb explained. The sound from the hive is said to have a soothing effect that “acts as salve to day-to-day stressors,” according to the BBC.

This is just the start of a trend and we want in on it. Should our tiny house feature the sights/smells/sounds of angry rattlesnakes or a swarm of locusts?
 

Joysticks can make the world a better place

Someday, it might be possible for surgeons to treat a stroke or aneurysm during the “golden hour,” even if they’re not in the same hospital as the patient. MIT engineers have created a robotic system that can be controlled remotely with a modified joystick, so the patient can go to a closer, smaller hospital and be treated by a surgeon at a larger facility through live imaging.

Endovascular surgery seems difficult enough with the patient and doctor in the same hospital, “but having a robot twist with the same level of sophistication [as a surgeon] is challenging,” Yoonho Kim, lead author of a study in Science Robotics, said in a written statement. “Our system is based on a fundamentally different mechanism.”

It involves “a medical-grade robotic arm with a magnet attached to its wrist. With a joystick and live imaging, an operator can adjust the magnet’s orientation and manipulate the arm to guide a soft and thin magnetic wire through arteries and vessels,” MIT explained in the statement.

The system was tested using life-like models, and it took each surgeon about an hour of training to learn how to use the new joystick and other equipment. Another perk: No exposure to radiation from x-ray imaging.

If someone you know is obsessed with video games, stop thinking “slacker” and start thinking “neurosurgeon.”
