SAN FRANCISCO – In locally advanced rectal cancer, fragmentation of radiotherapy and surgery comes at a cost, even at academic medical centers, according to a new analysis of data from the National Cancer Center Database. Researchers found that survival was higher when care was integrated – that is, both the surgery and the radiotherapy were performed at the same location.

The study paints a complex picture. Academic settings had a higher frequency of fragmented care than comprehensive community and community hospitals, but treatment in them was associated with better overall survival. However, patients who received fragmented care at academic hospitals had no survival advantage over the other institutions, according to Kyle Freischlag, MD, an intern at the University of Iowa, Iowa City, who presented the study at the annual clinical congress of the American College of Surgeons. The study was conducted at Duke University, Durham, N.C., during Dr. Freischlag’s time there.

Cancer care is becoming more centralized, with the expectation that patients will travel to specialty centers for treatment. But this isn’t possible for all patients, so some may get surgery at one locale, and radiation therapy at a closer, more convenient center.

The push for centralization of cancer care is embodied by the National Accreditation Program for Rectal Cancer, which accredits hospitals to be centers of excellence for rectal cancer surgery. “It’s a great program, it’s very comprehensive. But it is resource intensive to become accredited, so realistically, I think it will be mostly larger-volume hospitals that will apply for accreditation,” said Elise Lawson, MD, in an interview. Dr. Lawson is assistant professor of surgery at University of Wisconsin–Madison, and moderated the session where the research was presented.

“It is a great first step to improving the quality of rectal cancer care, but this study highlights that accreditation of large-volume centers may not be enough, and that we have to be careful that we aren’t going to exacerbate existing disparities in access and quality of care for patients who live in rural settings,” Dr. Lawson added.

In an analysis of 28,227 patients between 2006 and 2015, 17,663 of whom had integrated care, the researchers found that integrated care patients had a lower likelihood of 30-day unplanned readmissions (6.2% vs. 7.0%; P =.01), and those with fragmented care experienced higher mortality (hazard ratio, 1.07; 95% confidence interval, 1.01-1.12). Treatment in an academic center was associated with lower mortality overall than treatment in community centers (HR, 0.881; P =.005).

Fragmented care was more common in academic centers (40% vs. 36% in comprehensive community centers vs. 37% in community centers, P less than .001). Within academic centers, 5-year overall survival was worse with fragmented versus integrated care (70% vs. 74%; P =.00016).

The researchers found that performance of surgery at an academic center was itself a predictor of better survival (odd ratio, 0.88; 95% CI, 0.81-0.96). Integrated care at an academic center was associated with lower 30-day mortality (0.5% vs. 0.6% in integrated comprehensive community centers vs. 1.1% in integrated community centers; P = .038) and better 5-year overall survival (73% vs. 71% vs. 66%; HR, 0.85; 95% CI, 0.75-0.98; P less than .0001). “However, that survival benefit seen in academic hospitals disappeared when they had fragmented care,” Dr. Freischlag noted.

The study is limited by its retrospective nature, though the researchers did adjust for clinical and demographic characteristics, and selection bias for fragmented care should be generalizable across hospital types.

Dr. Freischlag believes that centralization has created additional financial and emotional burdens on patients, reduced the chances of patients receiving adjuvant therapy and completing radiation therapy, and led to increased stage at diagnosis, all factors that might explain the survival difference. He called for efforts to reduce fragmentation, and to conduct surgery at academic centers whenever possible, since that is associated with a survival advantage.

Dr. Lawson agreed, and called for a greater focus on improving care across centers. “It’s a problem if we’re only improving the large volume centers and not thinking about the burden that travel places on patients that live far away from these centers. This study is further showing that it matters not just where you get surgery, but also chemotherapy and radiation – so we need to think about how to coordinate comprehensive care for patients with rectal cancer better.”

The study received no external funding. Dr. Freischlag and Dr. Lawson reported no relevant conflicts of interest.

CHARLOTTE, NC – After a child undergoes epilepsy surgery, families may perceive a sustained improvement in the child’s behavior and cognition, regardless of whether the child is seizure-free, according to a study presented at the annual meeting of the Child Neurology Society. The presence of comorbidities such as mood disorders and autism may influence the likelihood of perceived improvement, whereas the type of surgery may not.

“The parents and the families of the patients perceive that, even if the patients are not completely seizure free, the behavior and cognitive outcomes are better if there is some sort of seizure improvement,” said Trishna Kantamneni, MD, director of pediatric epilepsy at UC Davis in Sacramento.

To assess behavioral and cognitive outcomes following pediatric epilepsy surgery and to identify factors that predict improvement, Dr. Kantamneni and colleagues at the Cleveland Clinic Epilepsy Center retrospectively reviewed 126 patients younger than 18 years who underwent epilepsy surgery for medically refractory epilepsy during 2009-2016.

The primary outcome measure was the Impact of Childhood Neurologic Disability Scale (ICNDS), a parent-reported scale that assesses the behavior, cognition, and physical or neurologic disability of children with epilepsy. Parents completed the ICNDS preoperatively and at 6, 12, and 24 months after surgery. The researchers constructed separate linear mixed effects models to identify predictors of postoperative changes in ICNDS score.

Of the 126 patients, 62.7% were male, the median duration of epilepsy was 4.7 years, and 69.8% were seizure-free at the 2-year follow-up. Postoperative ICNDS scores were available for 103 patients at 6 months and for 54 patients at 24 months.

Before surgery, the average total ICNDS score was 55.7. At 6 months after surgery, the average score was 34.6, and at 24 months, it was 32.1, representing significant improvement from baseline.

In addition, behavior, cognition, and epilepsy subscores also improved post operatively, and the improvement persisted through 24 months. ICNDS scores significantly improved “even in patients who were not seizure-free after surgery,” by an average of about 22 points, the researchers said.

The absence of comorbid autism, cognitive impairment, and global developmental impairment and the absence of anxiety, depression, and ADHD were predictors of improved total ICNDS scores. Tumor pathology and being seizure free at 2 years also predicted improved scores. Duration and type of epilepsy, the number of antiepileptic drugs that patients were taking before surgery, and lobe of surgery were not predictive of improved ICNDS scores.

SAN FRANCISCO – Nearly one in three surgical residents report experiencing gender-based discrimination, and one in six report racial discrimination, with mistreatment linked to burnout and suicidal thoughts, according to data presented at the annual clinical congress of the American College of Surgeons.

Published simultaneously in the New England Journal of Medicine, the cross-sectional national survey of 7,409 residents across all 262 surgical residency programs investigated the impact of mistreatment on burnout rates and suicidal thoughts. The sample included 99.3% of all eligible U.S. trainees.

The survey found that 31.9% of all respondents – 65.1% of women and 10% of men – said they had experienced discrimination because of their self-reported gender, and 16.6% had experienced racial discrimination. In the case of both gender-based and racial discrimination, nearly half of respondents who had experienced these identified patients and patients’ families as the source.

One-third of female respondents (33%) had been on the receiving end of verbal emotional abuse, as had 28.3% of male respondents. Most of the abuse came from other surgeons.

Around 1 in 10 residents – 19.9% of women and 3.9% of men – had experienced sexual harassment. In around one-third of cases, the source was other surgeons, and in one-third the source was patients and their families.

Nearly half of all the residents said they had experienced some form of mistreatment, 19% said they experienced it a few times a month, and 30.9% said it happened a few times a year.

The survey found that 38.5% of residents experienced the symptoms of burnout – such as emotional exhaustion and depersonalization – at least once a week. The incidence was higher in women than in men (42.4% vs. 35.9%), with women reporting a higher prevalence of emotional exhaustion than men. Nearly 1 in 20 (4.5%) reported having suicidal thoughts (5.3% of women and 3.9% of men).

Researchers found that the more mistreatment a resident experienced, the greater the frequency of burnout symptoms. Those who reported experiencing mistreatment a few times a year had a twofold greater odds of burnout, compared with those who had not experienced any mistreatment. Those who experienced mistreatment a few times a month or more had nearly threefold higher odds of burnout. Similarly, increasing exposure to mistreatment was also associated with stepwise increases in the odds of suicidal thoughts.

“Mistreatment is a frequent experience for general surgery residents in the United States, and is associated with burnout and suicidal thoughts,” wrote Yue-Yung Hu, MD, from the Surgical Outcomes and Quality Improvement Center at Northwestern University, Chicago, and coauthors. “Our results provide initial insights on how we may build safer, more equitable and more effective education environments for trainees.”

The study was supported by the American College of Surgeons, the Accreditation Council for Graduate Medical Education, and the American Board of Surgery. Two authors were supported by grants from the Agency for Healthcare Research and Quality, and one by a grant from the National Institutes of Health. One author was an employee of the Accreditation Council for Graduate Medical Education.

PHILADELPHIA – Ovarian tissue cryopreservation should no longer be considered experimental, Sherman J. Silber, MD, said at the annual meeting of the American Society for Reproductive Medicine.

That claim is based on more than 20 years of experience at his center performing the procedure and results he presented from patients for whom frozen ovarian tissue has been reimplanted resulting in a spontaneous pregnancy.

“For prepubertal girls with cancer and for patients who have already had a preliminary round of chemotherapy, ovarian tissue freezing is the only method available to preserve their fertility,” said Dr. Silber, of the Infertility Center of St. Louis in Chesterfield, Missouri. “It is also the only method available to preserve their fertility.”

“I have very strong feelings about this,” he added. “It has huge societal implications for insurance payments.”

Dr. Silber presented results of ovarian tissue freezing and reimplantation at his center beginning in 1997, where 115 patients between the ages of 2 and 35 years underwent the procedure using the same technique. Of these patients, 14 women came back years later to have their frozen ovary cortex reimplanted. Dr. Silber and his group followed these patients monthly for more than 2 years after reimplantation for signs of return of menses, hormonal changes, pregnancy, and live birth.

Most of the patients who chose ovarian tissue freezing had cancer. Eight patients underwent the procedure after being diagnosed with solid tissue cancer and three had leukemia, while two patients underwent ovarian tissue freezing due to premature ovarian failure, and one because of multiple sclerosis. Patients who underwent reimplantation were menopausal for at least 3 years, said Dr. Silber.

Dr. Silber also described the technique used for reimplantation. After the cortical tissue was thawed, the tissue was quilted into one piece from three to five slices using 9-0 nylon interrupted sutures. The quilted tissue was then sutured to the medulla after the surgeon completely removed the dead cortex from the other ovary. “Hemostasis was achieved with micro bipolar forceps,” said Dr. Silber. “Constant irrigation was employed with pulsed heparinized media because we wanted to avoid adhesions, and we wanted to try for spontaneous pregnancy rather than IVF.”

“Then, we put [the quilted ovarian slices] on to the medulla on the other side in such a way that the fallopian tube would be able to reach and catch any egg that’s ovulated during that time,” he added.

Dr. Silber and his group found that, over time, follicle-stimulating hormone (FSH) levels sharply decreased to normal or near-normal levels between 69 days and 133 days after the procedure while Anti-Müllerian hormone (AMH) levels dramatically rose to higher levels between 133 days and 227 days post-procedure before dropping to very low levels, “and the AMH remained at low levels despite the fact that [transplants] would last 8 to 10 years,” said Dr. Silber.

Of the 14 cases where frozen ovarian tissue was reimplanted, 11 patients (78%) achieved pregnancy, 10 patients (71%) delivered healthy babies, and 1 patient (9%) experienced a miscarriage. All patients had spontaneous pregnancies, and none used in vitro fertilization (IVF), noted Dr. Silber. There were 2 patients who had four children from transplanted ovarian tissue, and 2 of 3 patients with leukemia had a total of five children.

Additionally, Dr. Silber’s group examined the literature for other examples of ovarian tissue reimplantation after cryopreservation to determine how many live births resulted from the procedure. They found an additional 170 live births in addition to the 15 live births at their center, with a pregnancy rate ranging from 31% to 71% in different studies. Cancer was not transmitted from mother to child in any case, said Dr. Silber.

Compared with egg freezing, there is a benefit to performing ovarian tissue freezing, even after chemotherapy has begun, noted Dr. Silber. The cost of ovarian tissue freezing is also roughly one-tenth that of egg freezing, and the procedure is less burdensome than multiple cycles with the potential for ovarian hyperstimulation, and it restores the hormone function and the fertility of eggs after reimplantation.

“Because the greater primordial follicle recruitment decreases as the ovarian reserve decreases, you can put a piece of ovary tissue back every 8 years, and a woman can have endocrine function until she’s 100 years old,” said Dr. Silber.

Dr. Silber reported no relevant conflicts of interest.

PHILADELPHIA – Ovarian tissue cryopreservation should no longer be considered experimental, Sherman J. Silber, MD, said at the annual meeting of the American Society for Reproductive Medicine.

That claim is based on more than 20 years of experience at his center performing the procedure and results he presented from patients for whom frozen ovarian tissue has been reimplanted resulting in a spontaneous pregnancy.

“For prepubertal girls with cancer and for patients who have already had a preliminary round of chemotherapy, ovarian tissue freezing is the only method available to preserve their fertility,” said Dr. Silber, of the Infertility Center of St. Louis in Chesterfield, Missouri. “It is also the only method available to preserve their fertility.”

“I have very strong feelings about this,” he added. “It has huge societal implications for insurance payments.”

Dr. Silber presented results of ovarian tissue freezing and reimplantation at his center beginning in 1997, where 115 patients between the ages of 2 and 35 years underwent the procedure using the same technique. Of these patients, 14 women came back years later to have their frozen ovary cortex reimplanted. Dr. Silber and his group followed these patients monthly for more than 2 years after reimplantation for signs of return of menses, hormonal changes, pregnancy, and live birth.

Most of the patients who chose ovarian tissue freezing had cancer. Eight patients underwent the procedure after being diagnosed with solid tissue cancer and three had leukemia, while two patients underwent ovarian tissue freezing due to premature ovarian failure, and one because of multiple sclerosis. Patients who underwent reimplantation were menopausal for at least 3 years, said Dr. Silber.

Dr. Silber also described the technique used for reimplantation. After the cortical tissue was thawed, the tissue was quilted into one piece from three to five slices using 9-0 nylon interrupted sutures. The quilted tissue was then sutured to the medulla after the surgeon completely removed the dead cortex from the other ovary. “Hemostasis was achieved with micro bipolar forceps,” said Dr. Silber. “Constant irrigation was employed with pulsed heparinized media because we wanted to avoid adhesions, and we wanted to try for spontaneous pregnancy rather than IVF.”

“Then, we put [the quilted ovarian slices] on to the medulla on the other side in such a way that the fallopian tube would be able to reach and catch any egg that’s ovulated during that time,” he added.

SAN ANTONIO – Fibrinogen concentrate was noninferior to cryoprecipitate for controlling bleeding following cardiac surgery in the randomized FIBRES trial, Canadian investigators reported.

Neil Osterweil/MDedge News

Among 827 patients undergoing cardiopulmonary bypass, there were no significant differences in the use of allogenenic transfusion products within 24 hours of surgery for patients assigned to receive fibrinogen concentrate for control of bleeding, compared with patients who received cryoprecipitate, reported Jeannie Callum, MD, from Sunnybrook Health Sciences Centre in Toronto, on behalf of coinvestigators in the FIBRES trial.

Fibrinogen concentrate, commonly used to control postoperative bleeding in Europe, was associated with numerically, but not statistically, lower incidence of both adverse events and serious adverse events than cryoprecipitate, the current standard of care in North America.

“Given its safety and logistical advantages, fibrinogen concentrate may be considered in bleeding patients with acquired hypofibrinogenemia,” Dr. Callum said at the annual meeting of the AABB, the group formerly known as the American Association of Blood Banks.

Results of the FIBRES trial were published simultaneously in JAMA (2019 Oct 21. doi: 10.1001/jama.2019.17312).

Acquired hypofibrinogenemia, defined as a fibrinogen level below the range of 1.5-2.0 g/L, is a major cause of excess bleeding after cardiac surgery. European guidelines on the management of bleeding following trauma or cardiac surgery recommend the use of either cryoprecipitate or fibrinogen concentrate to control excessive bleeding in patients with acquired hypofibrinogenemia, Dr. Callum noted.

Cryoprecipitate is a pooled plasma–derived product that contains fibrinogen, but also fibronectin, platelet microparticles, coagulation factors VIII and XIII, and von Willebrand factor.

Additionally, fibrinogen levels in cryoprecipitate can range from as low as 3 g/L to as high as 30 g/L, and the product is normally kept and shipped frozen, and is then thawed for use and pooled prior to administration, with a shelf life of just 4-6 hours.

In contrast, fibrinogen concentrates “are pathogen-reduced and purified; have standardized fibrinogen content (20 g/L); are lyophilized, allowing for easy storage, reconstitution, and administration; and have longer shelf life after reconstitution (up to 24 hours),” Dr. Callum and her colleagues reported.

Despite the North American preference for cryoprecipitate and the European preference for fibrinogen concentrate, there have been few studies directly comparing the two products, which prompted the FIBRES investigators to design a head-to-head trial.

The randomized trial was conducted in 11 Canadian hospitals with adults undergoing cardiac surgery with cardiopulmonary bypass for whom fibrinogen supplementation was ordered in accordance with accepted clinical standards.

Patients were randomly assigned to received either 4 g of fibrinogen concentrate or 10 units of cryoprecipitate for 24 hours, with all patients receiving additional cryoprecipitate as needed after the first day.

Of 15,412 cardiac patients treated at the participating sites, 827 patients met the trial criteria and were randomized. Because the trial met the prespecified stopping criterion for noninferiority of fibrinogen at the interim analysis, the trial was halted, leaving the 827 patients as the final analysis population.

The mean number of allogeneic blood component units administered – the primary outcome – was 16.3 units in the fibrinogen concentrate group and 17.0 units in the cryoprecipitate group (mean ratio, 0.96; P for noninferiority less than .001; P for superiority = .50).

Fibrinogen was also noninferior for the secondary outcomes of individual 24-hour and cumulative 7-day blood component transfusions, and in a post-hoc analysis of cumulative transfusions measured from product administration to 24 hours after termination of cardiopulmonary bypass. These endpoints should be interpreted with caution, however, because they were not corrected for type 1 error, the investigators noted.

Fibrinogen concentrate also appeared to be noninferior for all defined subgroups, except for patients who underwent nonelective procedures, which included all patients in critical state before surgery.

Adverse events (AEs) of any kind occurred in 66.7% of patients with fibrinogen concentrate vs. 72.7% of those on cryoprecipitate. Serious AEs occurred in 31.5% vs. 34.7%, respectively.

Thromboembolic events – stroke or transient ischemic attack, amaurosis fugax (temporary vision loss), myocardial infarction, deep-vein thrombosis, pulmonary embolism, other-vessel thrombosis, disseminated intravascular coagulation, or thrombophlebitis – occurred in 7% vs. 9.6%, respectively.

The investigators acknowledged that the study was limited by the inability to blind the clinical team to the product used, by the adult-only population, and by the likelihood of variable dosing in the cryoprecipitate group.

Advantages of fibrinogen concentrate over cryoprecipitate are that the former is pathogen reduced and is easier to deliver, the investigators said.

“One important consideration is the cost differential that currently favors cryoprecipitate, but this varies across regions, and the most recent economic analysis failed to include the costs of future emerging pathogens and did not include comprehensive activity-based costing,” the investigators wrote in JAMA.

The trial was sponsored by Octapharma AG, which also provided fibrinogen concentrate. Cryoprecipitate was provided by the Canadian Blood Services and Héma-Québec. Dr. Callum reported receiving grants from Canadian Blood Services, Octapharma, and CSL Behring during the conduct of the study. Multiple coauthors had similar disclosures.

Breast implants sold in the United States may soon require a boxed warning in their label, along with other label changes proposed by the Food and Drug Administration aimed at better informing prospective patients and clinicians of the potential risks from breast implants.

Mitchel L. Zoler/MDedge News

Other elements of the proposed labeling changes include creation of a patient-decision checklist, new recommendations for follow-up imaging to monitor for implant rupture, inclusion of detailed and understandable information about materials in the device, and provision of a device card to each patient with details on the specific implant they received.

These labeling changes all stemmed from a breast implant hearing held by the agency’s General and Plastic Surgery Devices Panel in March 2019, according to the draft guidance document officially released by the FDA on Oct. 24.

The proposed labeling changes were generally welcomed by patient advocates and by clinicians as a reasonable response to the concerns discussed at the March hearing. In an earlier move to address issues brought up at the hearing, the FDA in July arranged for a recall for certain Allergan models of textured breast implants because of their link with the development of breast implant–associated anaplastic large cell lymphoma (BIA-ALCL).

The boxed warning proposed by the FDA would highlight four specific facts that patients, physicians, and surgeons should know about breast implants: They are not considered lifetime devices, the chance of developing complications from implants increases over time, some complications require additional surgery, and placement of breast implants has been associated with development of BIA-ALCL and may also be associated with certain systemic symptoms.

The FDA also proposed four other notable labeling changes:

• Creation of a patient-decision checklist to better systematize the informed consent process and make sure that certain aspects of breast implant placement are clearly brought to patients’ attention. The FDA proposed that patients sign their checklist attesting to having read and understood the information and that patients receive a take-home copy for their future reference. Proposed elements of the checklist include situations to not use breast implants; considerations for successful implant recipients; the risks of breast implant surgery; the importance of appropriate physician education, training, and experience; the risk for developing BIA-ALCL or systemic symptoms; and discussion of options other than breast implants.
• A new scheme for systematically and serially using imaging to screen for implant rupture that designates for the first time that ultrasound is an acceptable alternative to MRI and relies on a schedule by which either method initially screens the implant 5-6 years post operatively and then every 2 years thereafter.
• Detailed and understandable information about each material component of the implant with further information on possible adverse health effects of these compounds.
• A device card that patients should receive after their surgery with the implant’s name, serial number, and other identifiers; the boxed warning information; and a web link for accessing more up-to-date information.

The patient group Breast Implant Victim Advocacy praised the draft guidance. “The March Advisory Committee meeting seems to have prompted a shift by the FDA, surgeons, and industry,” said Jamee Cook, cofounder of the group. “We are definitely seeing a change in patient engagement. The FDA has been cooperating with patients and listening to our concerns. We still have a long way to go in raising public awareness of breast implant issues, but progress over the past 1-2 years has been amazing.”

Diana Zuckerman, PhD, president of the National Center for Health Research in Washington, gave the draft guidance a mixed review. “The FDA’s draft includes the types of information that we had proposed to the FDA in recent months in our work with patient advocates and plastic surgeons,” she said. “However, it is not as informative as it should be in describing well-designed studies indicating a risk of systemic illnesses. Patients deserve to make better-informed decisions in the future than most women considering breast implants have been able to make” in the past.

Patricia McGuire, MD, a St. Louis plastic surgeon who specializes in breast surgery and has studied breast implant illness, declared the guidance to be “reasonable.”

“I think the changes address the concerns expressed by patients during the [March] hearing; I agree with everything the FDA proposed in the guidance document,” Dr. McGuire said. “The boxed warning is reasonable and needs to be part of the informed consent process. I also agree with the changes in screening implants postoperatively. Most patients do not get MRI examinations. High-resolution ultrasound is more convenient and cost effective.”

The boxed warning was rated as “reasonably strong” and “the most serious step the FDA can take short of taking a device off the market,” but in the case of breast implants, a wider recall of textured implants than what the FDA arranged last July would be even more appropriate, commented Sidney M. Wolfe, MD, founder and senior adviser to Public Citizen. He also faulted the agency for not taking quicker action in mandating inclusion of the proposed boxed warning.

Issuing the labeling changes as draft guidance “is a ministep forward,” but also a process that “guarantees delay” and “creeps along at a dangerously slow pace,” Dr. Wolfe said. “The FDA is delaying what should be inevitable. The agency could put the boxed warning in place right now if they had the guts to do it.”

Dr. McGuire has been a consultant to Allergan, Establishment Labs, and Hans Biomed. Ms. Cook, Dr. Zuckerman, and Dr. Wolfe reported having no commercial disclosures.

Proposed elements of the checklist include situations to not use breast implants; considerations for successful implant recipients; the risks of breast implant surgery; the importance of appropriate physician education, training, and experience; the risk for developing BIA-ALCL or systemic symptoms; and discussion of options other than breast implants.
• A new scheme for systematically and serially using imaging to screen for implant rupture that designates for the first time that ultrasound is an acceptable alternative to MRI and relies on a schedule by which either method initially screens the implant 5-6 years post operatively and then every 2 years thereafter.
• Detailed and understandable information about each material component of the implant with further information on possible adverse health effects of these compounds.
• A device card that patients should receive after their surgery with the implant’s name, serial number, and other identifiers; the boxed warning information; and a web link for accessing more up-to-date information.

The patient group Breast Implant Victim Advocacy praised the draft guidance. “The March Advisory Committee meeting seems to have prompted a shift by the FDA, surgeons, and industry,” said Jamee Cook, cofounder of the group. “We are definitely seeing a change in patient engagement. The FDA has been cooperating with patients and listening to our concerns. We still have a long way to go in raising public awareness of breast implant issues, but progress over the past 1-2 years has been amazing.”

Diana Zuckerman, PhD, president of the National Center for Health Research in Washington, gave the draft guidance a mixed review. “The FDA’s draft includes the types of information that we had proposed to the FDA in recent months in our work with patient advocates and plastic surgeons,” she said. “However, it is not as informative as it should be in describing well-designed studies indicating a risk of systemic illnesses. Patients deserve to make better-informed decisions in the future than most women considering breast implants have been able to make” in the past.

Patricia McGuire, MD, a St. Louis plastic surgeon who specializes in breast surgery and has studied breast implant illness, declared the guidance to be “reasonable.”

“I think the changes address the concerns expressed by patients during the [March] hearing; I agree with everything the FDA proposed in the guidance document,” Dr. McGuire said. “The boxed warning is reasonable and needs to be part of the informed consent process. I also agree with the changes in screening implants postoperatively. Most patients do not get MRI examinations. High-resolution ultrasound is more convenient and cost effective.”

The boxed warning was rated as “reasonably strong” and “the most serious step the FDA can take short of taking a device off the market,” but in the case of breast implants, a wider recall of textured implants than what the FDA arranged last July would be even more appropriate, commented Sidney M. Wolfe, MD, founder and senior adviser to Public Citizen. He also faulted the agency for not taking quicker action in mandating inclusion of the proposed boxed warning.

Issuing the labeling changes as draft guidance “is a ministep forward,” but also a process that “guarantees delay” and “creeps along at a dangerously slow pace,” Dr. Wolfe said. “The FDA is delaying what should be inevitable. The agency could put the boxed warning in place right now if they had the guts to do it.”

Dr. McGuire has been a consultant to Allergan, Establishment Labs, and Hans Biomed. Ms. Cook, Dr. Zuckerman, and Dr. Wolfe reported having no commercial disclosures.

Breast implants sold in the United States may soon require a boxed warning in their label, along with other label changes proposed by the Food and Drug Administration aimed at better informing prospective patients and clinicians of the potential risks from breast implants.

Other elements of the proposed labeling changes include creation of a patient-decision checklist, new recommendations for follow-up imaging to monitor for implant rupture, inclusion of detailed and understandable information about materials in the device, and provision of a device card to each patient with details on the specific implant they received.

These labeling changes all stemmed from a breast implant hearing held by the agency’s General and Plastic Surgery Devices Panel in March 2019, according to the draft guidance document officially released by the FDA on Oct. 24.

The proposed labeling changes were generally welcomed by patient advocates and by clinicians as a reasonable response to the concerns discussed at the March hearing. In an earlier move to address issues brought up at the hearing, the FDA in July arranged for a recall for certain Allergan models of textured breast implants because of their link with the development of breast implant–associated anaplastic large cell lymphoma (BIA-ALCL).

The boxed warning proposed by the FDA would highlight four specific facts that patients, physicians, and surgeons should know about breast implants: They are not considered lifetime devices, the chance of developing complications from implants increases over time, some complications require additional surgery, and placement of breast implants has been associated with development of BIA-ALCL and may also be associated with certain systemic symptoms.

The FDA also proposed four other notable labeling changes:

• Creation of a patient-decision checklist to better systematize the informed consent process and make sure that certain aspects of breast implant placement are clearly brought to patients’ attention. The FDA proposed that patients sign their checklist attesting to having read and understood the information and that patients receive a take-home copy for their future reference. Proposed elements of the checklist include situations to not use breast implants; considerations for successful implant recipients; the risks of breast implant surgery; the importance of appropriate physician education, training, and experience; the risk for developing BIA-ALCL or systemic symptoms; and discussion of options other than breast implants.

• Detailed and understandable information about each material component of the implant with further information on possible adverse health effects of these compounds.

SAN FRANCISCO – At 5 years, the rates of disabling stroke or death were similar among patients with severe aortic stenosis and intermediate surgical risk who underwent transcatheter aortic valve replacement or surgical aortic valve replacement.

Doug Brunk/MDedge News

At the same time, patients who underwent TAVR using a transthoracic approach had poorer outcomes, compared with their counterparts who underwent SAVR, Vinod H. Thourani, MD, reported at the Transcatheter Cardiovascular Therapeutics annual meeting. The findings come from an analysis of the PARTNER 2A trial, the largest randomized study ever conducted in the field of TAVR and SAVR.

In an effort to compare the key clinical outcomes, bioprosthetic valve function, and quality-of-life measures at 5 years for TAVR versus surgery, Dr. Thourani and his colleagues used data from 2,032 intermediate-risk patients with severe AS assigned to either TAVR or SAVR at 57 centers in the PARTNER 2A trial. Their mean age was 82 years, and their average Society of Thoracic Surgery risk score was 5.8%. The 2-year primary endpoint was all-cause death or disabling stroke in the intention-to-treat (ITT) population. At 5 years, the researchers analyzed all primary and secondary clinical and echo endpoints in both ITT and prespecified as-treated populations.

At 5 years, the primary endpoint of death and disabling stroke at 5 years was 47.9% in the TAVR group and 43.4% in the surgery group, a difference that did not reach statistical significance (hazard ratio, 1.09; P = .21). In the transfemoral cohort, rates of the primary endpoint were also similar between TAVR and SAVR (44.5% vs. 42%, respectively; HR, 1.02; P = .80). In the transthoracic cohort, however, the researchers observed a divergence in the primary outcome starting at year 1, such that it was higher with TAVR at 5 years, compared with SAVR (59.3% vs. 48.3%; P = .03), reported Dr. Thourani, chair of cardiac surgery at Medstar Heart and Vascular Institute, Washington.

When he and his colleagues examined freedom from aortic valve reintervention at 5 years, the hazard ratios showed some difference between TAVR and SAVR (HR, 3.93; P = .003), yet clinically the freedom from reintervention rate was very high (96.8% vs. 99.4%, respectively). “The other issue we’ve been interested in is the difference between mean aortic valve gradients between the groups,” Dr. Thourani said at the meeting. “There was no difference in mean aortic valve gradients between TAVR and SAVR at 5 years (a mean of 11.4 mm Hg vs. 10.8 mm Hg, respectively; P = .23).”

Paravalvular regurgitation (PVR) was more common in the TAVR vs. SAVR group at all follow-up times (P less than .001 in all categories). By year 5, the proportion of patients with moderate to severe PVR was 6.5% in the TAVR group vs. 0.4% in the SAVR group, respectively, while the proportion of those with mild PVR was 26.8%, compared with 5.9%.

In other findings, no difference in mortality was seen in the TAVR cohort between those with mild PVR and no or trace PVR (48.7% vs. 41.1%; P = .07). However, those with moderate to severe PVR at the end of the procedure had an increased mortality at the end of 5 years (64.8%; P = .007). “If you had none or trace PVR at baseline, there was no major difference in mortality between the two groups at 2 years,” Dr. Thourani said. “That difference was maintained at 5 years.”

The overall findings, he continued, support the notion that TAVR should be considered as an alternative to surgery in intermediate-risk patients with severe aortic stenosis. “However, in patients without acceptable transfemoral access, surgery may be the preferred alternative,” he said.

Roxana Mehran, MD,, director of interventional cardiovascular research and clinical trials at Mount Sinai School of Medicine, New York, commented that the reassurance of the same outcomes at 5 years between the two approaches “makes TAVR superior. It’s a less invasive and durable result. One of the things we have yet to figure out is the need for anticoagulation to prevent stroke in these patients. We have very little data and understanding about that.”

The PARTNER 2A study was funded by Edwards Lifesciences. Dr. Thourani has received grant or research support from and participation in steering committees for Edwards Lifesciences, Abbott Vascular, Boston Scientific, Gore Vascular, JenaValve, and Cryolife.

Patients discharged with plug-unplug catheters after pelvic reconstructive surgery did not have adverse effects and reported less difficulty with catheter management and activities of daily living than women who were discharged with a continuous drainage catheter, a study has found.

“Plug-unplug catheter management technique is an acceptable method that does not appear to cause adverse events and may be considered for short-term catheterization after pelvic reconstructive surgery,” said Sarah Boyd, MD,* of the division of urogynecology at Hartford (Conn.) Hospital, and coinvestigators wrote in Obstetrics & Gynecology.

A total of 63 women who had a failed postoperative voiding trial after surgery for prolapse, with or without a concomitant incontinence procedure, were randomized to receive a 16-French transurethral catheter that was either attached to a leg bag (31 patients) or capped with a plastic plug (32 patients). Women in the second group – the plug-unplug group – were instructed to intermittently drain the bladder by uncapping the catheter when they felt the urge to void, or in the absence of urge, every 4 hours. All were scheduled for an outpatient voiding trial 5-7 days after discharge.

The first 30 study participants who did not require postoperative catheterization were assigned to a “reference,” or control, arm.

All patients in the study completed an activity assessment scale that covers both sedentary and ambulatory activities and is validated in women undergoing pelvic reconstructive surgery (Female Pelvic Med Reconstr Surg. 2012 Jul-Aug;18[4]:205-10); scores on the activity assessment scale (0-100) served as the primary outcome. Patients also answered questionnaires about their satisfaction and postoperative pain – and in the catheter arms, their experiences with the catheter.

The investigators found no difference in postoperative activity assessment scale scores (plug-unplug, 70; continuous drainage, 68; and reference arm, 79), However, patients with a continuous catheter indicated in the other evaluations that they had more difficulty managing the catheter and felt it impeded activities and the wearing of clothing they would otherwise use.

The activity scale, the investigators noted, may not have captured differences in activity during the first week postoperatively because patients are commonly instructed to restrict some of the activities assessed in the scale.

Regarding infection, there was no difference in the rate of positive urine cultures or treatment for urinary tract infection between the catheter arms during a 3-month follow-up period, “despite the theoretical concern that plugging and unplugging a catheter disrupts the closed catheter system, thus increasing the risk of infection,” the investigators wrote. However, the study was not powered to detect a difference in the risk of infection as it was for the primary outcome.

There was no difference between the catheter arms in the percentage of women who used narcotic or nonnarcotic pain medication, and overall patient satisfaction was similar.

The majority of patients passed their outpatient voiding trials at the initial postoperative visit (72% plug-unplug and 58% continuous). “Interestingly, patients in the plug-unplug arm had significantly higher voided volumes and almost half of the [postvoid residual volume] at the [5-7 day postoperative voiding trial] compared with the continuous drainage arm.” This suggests, Dr. Boyd and colleagues wrote, that patients using the plug-unplug catheter “could have undergone a voiding trial sooner.”

Offering patients options for catheter management is “valuable,” and providing them with a technique that is “easier to manage may decrease the catheter burden and improve patient experience,” the investigators added.

Luis E. Sanz, MD, director of urogynecology and pelvic reconstructive surgery at Virginia Hospital Center, Arlington, said, “I think that the plug and unplug drainage bladder catheter after reconstructive surgery is much more physiologic and ‘user friendly’ than continuous drainage. And [there is] no need for a leg bag, which is very inconvenient to the patient.”

Dr. Sanz, an Ob.Gyn. News Editorial Advisory Board member who was not involved in the study, was asked to provide a comment.

Dr. Sanz, an Ob.Gyn. News Editorial Advisory Board member who was not involved in the study, was asked to provide a comment.

The authors did not report any potential conflicts of interest.

NEW ORLEANS – Race compatibility is a factor that can affect survival and needs to be considered when matching lung transplant candidates to potential donors, results from a large retrospective analysis suggest.

Specifically, whites had significantly worse survival when receiving lungs from African American donors in this registry analysis, according to study investigator Alexis Kofi Okoh, MD.

By contrast, donor-to-recipient race compatibility (DRRC) did not affect posttransplant survival among African American or Hispanic patients, said Dr. Okoh, who is with the lung transplant division at the Rutgers Robert Wood Johnson Medical School, New Brunswick, N.J.

While race mismatch has been shown to affect outcomes in kidney, heart, and liver transplant settings, the data for DRRC in lung transplant prior to this analysis generally has been limited to small, single-center studies, according to Dr. Okoh.

“If you do have the option, [race compatibility] should highly be considered, because it clearly has an impact on outcomes,” Dr. Okoh said in an interview here at the annual meeting of the American College of Chest Physicians.

Considering the race of both donor and recipient is especially important now that the lung transplant population is becoming more ethnically diverse, he added.

The study was based on an analysis of 19,504 lung transplant recipients in the prospectively maintained United Network for Organ Sharing (UNOS) database during 2006-2018. In that cohort, 16,485 recipients were white, 1,787 were African American, and 1,232 were Hispanic.

Race-matched donor organs were used in two-thirds (66.2%) of white recipients, about one-quarter (26.8%) of African American recipients, and one-third (33.0%) of Hispanic recipients.

Overall, survival post–lung transplant was significantly poorer among recipients who did not receive a race-matched organ in Kaplan-Meier survival estimates, Dr. Okoh said, though, that this effect was diminished after they adjusted for patient baseline characteristics (P = 0.2809).

For African American recipients, the unadjusted and adjusted survival estimates were no different regardless of donor race, and likewise, there were no apparent survival differences between Hispanic recipients who received race matched or mismatched organs.

Survival among white recipients, however, was significantly affected by race of the recipient, with decreased survival estimates noted even after adjustment for patient characteristics, according to Dr. Okoh’s presentation.

Results of regression analysis showed that white recipient/African American donor was the only race mismatch to significantly affect survival, Dr. Okoh said in the interview.

The posttransplant survival hazard ratios (and 95% confidence intervals) reported by Dr. Okoh with a no race mismatch serving as reference were 1.15 (1.08-1.23) for whites with African American donors, and 1.09 (1.01-1.18) for whites with Hispanic donors.

Dr. Okoh and coinvestigators reported no relevant conflicts in relation to their study.

AUSTIN, TEX. – Patients with Charcot-Marie-Tooth disease (CMT) receive a range of supportive care that includes physical therapy, surgery, medications, orthoses, and walking aids, according to patient-reported data presented at the annual meeting of the American Association of Neuromuscular and Electrodiagnostic Medicine. Patients describe approaches to CMT management that are broadly consistent with guidelines, researchers said.

“The range of different CMT treatments was wide,” reported Tjalf Ziemssen, MD, PhD, a researcher at Technische Universität Dresden in Germany, and colleagues. “Of note, high proportions of respondents had received pain medication, and a relatively high number had also visited pain specialists. These results indicate that pain may have a substantial impact on people with CMT.”

The data also suggest that “lower-limb problems and mobility issues have a considerable impact on people with CMT,” they said.

CMT is a rare, progressive neuropathy that leads to distal muscle weakness, muscle atrophy, and sensory loss. There is no cure, and patients rely on supportive care. Until recently, few studies have assessed the impact of CMT on patients’ lives.

An ongoing, international, 2-year observational study is collecting data from adults with CMT. Patients report data via an app called CMT & Me.

To examine patient-reported treatment patterns and care standards for CMT in the United States and the United Kingdom, Dr. Ziemssen and colleagues analyzed data through Aug. 5, 2019, about 9.5 months into the study. Their interim analysis included data from 439 patients, including 222 patients in the United Kingdom and 217 in the United States.

More than 70% of participants visit a family doctor each year, and a similar proportion visit a neurologist. About 40% visit physical therapists, orthotists, or podiatrists. Other health care professionals seen by patients include occupational therapists (20%), orthopedic surgeons (nearly 20%), and pain specialists (about 15%).

About 70% of participants had received rehabilitation therapy such as physical therapy or occupational therapy, and about 70% had used medications, most frequently nonopioid analgesics (about 50%) and antidepressants (about 30%).

More than 80% used orthoses or walking aids, most commonly ankle or leg braces, insoles, or walking sticks.

In addition, about half of respondents had undergone a surgery for CMT. The most common procedures were osteotomy, hammertoe correction, and plantar fascia release.

Together, patients saw about a dozen types of health care professionals. “Small proportions of participants had visited each professional, which suggests that the care requirements of CMT patients are varied,” the researchers said.

The study was sponsored by Pharnext. Dr. Ziemssen and coauthors received compensation for participating in the study. Other coauthors are employees of Pharnext or Vitaccess, the company that developed the app used in the study.
