Outpatient appendectomy success depends on patient selection, communication
Outpatient laparoscopic surgery for uncomplicated appendicitis can be safely implemented in a large county hospital that serves a poor, underserved population, findings from a prospective, observational trial have shown.
Outpatient appendectomy has gradually gained acceptance in the United States, and numerous studies support the practice. David R. Rosen, MD, of the University of Southern California, Los Angeles, and his colleagues considered the possible advantages of outpatient laparoscopic appendectomy for their institution, such as decreased length of stay, decreased costs, and fewer admissions.
The research team hypothesized that with a “well-defined protocol consisting of strict inclusion and exclusion criteria, clear patient instructions, and close observation to identify patients who would not succeed with the outpatient appendectomy treatment strategy, outpatient appendectomy would be feasible without worsening patient outcomes or satisfaction.”
The findings were published in the Journal of the American College of Surgeons (2017 May;224[5]:862-7).
The investigators conducted a study of patients presenting at a safety-net county hospital and diagnosed with acute appendicitis. A year-long observation period produced a control group of 178 admitted patients.
The outpatient protocol was then introduced. Patients were counseled on the possibility of their being discharged from the postanesthesia care unit (PACU), depending on intraoperative findings and their capacity to arrange a ride home and willingness to participate in postoperative follow-up. Patient education was a key element of the protocol. In all, 173 patients were identified for the outpatient program.
The intraoperative criteria for discharge from the PACU included no evidence of perforation or gangrene, and no surgical complications or adverse events. Patients were cleared for discharge if they met the following criteria: heart rate less than 100 beats/min; systolic blood pressure greater than 110 mm Hg; pain well controlled (less than 4 on a 1-10 scale); ambulatory; urinated since surgery; oral intake; and dressings dry without evidence of bleeding.
The patients had been thoroughly briefed on what to expect and problems that would necessitate a return to the emergency department. The physician assessed each patient’s readiness to be discharged, wrote a discharge order, and confirmed the pain medication prescription and follow-up appointment.
Of the 173 patients selected for the outpatient program, 113 (65%) ended up being discharged from the PACU. The reasons for these admissions included interoperative findings, failure to pass the discharge criteria, homelessness, and no transportation to get home.
The control and outpatient groups were similar demographically, except that the latter were on average significantly older (mean age 32.4 years vs. 36.6 years, respectively). The outpatient group had a significantly shorter operative time (69 minutes vs. 83 minutes), a significantly longer stay in the PACU (242 minutes vs.141 minutes), and a significantly shorter total postoperative length of stay (9 hours vs.19 hours).
There were no differences between the groups in terms of complications, postdischarge ED visits, or readmissions. Those who were discharged from the PACU had no postoperative complications and no readmissions.
The length of stay in the PACU gradually decreased for the outpatient group. “This can be attributed to the adoption of a new protocol,” the researchers noted. However, “we purposely did not want to rush the discharge process to ensure our patients and families had all questions answered and were comfortable leaving the hospital.”
A key component of the protocol was the follow-up appointment for all appendectomy patients; about one-third of both groups did not return for their follow-up appointments. Those missed follow-ups could mean some patients returned to another hospital, but the investigators suggested that this was unlikely.
“Because our hospital serves a patient population of low socioeconomic status and often without health insurance, our public hospital is often the only hospital to which they would present,” the investigators wrote.
Most of those who did return completed a questionnaire on their level of satisfaction. Survey results showed no differences in satisfaction between the groups and a generally positive view of the protocol among the outpatient group.
The study did not account for actual cost savings, but reduced hospital admissions and readmissions were achieved. Investigators assert that other studies have shown that each day of hospitalization avoided saves about $1,900.
“It is challenging to deliver high-quality, efficient care to an underserved population in a public hospital,” Dr. Rosen said in an interview. “In this setting, communication and patient education are vital components for success. By setting clear expectations and empowering patients to participate in their care, we can maximize our patients’ outcomes.”

Personalized snoring video boosts CPAP adherence
BOSTON – Showing patients videos of themselves having apneic episodes may convince them to use continuous positive airway pressure (CPAP), suggests the first results of an ongoing randomized clinical trial.
The investigators based their research project design on a previous pilot study that showed improved adherence to CPAP in patients who were shown videos of themselves sleeping while participating in a sleep study, Mark S. Aloia, PhD, said in a presentation at the annual meeting of the Associated Professional Sleep Societies.
In the new study, patients who had been recently diagnosed with sleep apnea were randomly assigned to participate in one of the three treatment groups. All three groups received sleep apnea and CPAP education prior to the use of CPAP. One group also watched videos of themselves sleeping, snoring, and gasping for air, and another group watched videos of a stranger sleeping and having apneic events.
After adjustment for age, educational level, and baseline sleep apnea severity, those who watched videos of themselves still used their CPAP devices more than 2 hours per night longer than did patients in each of the groups receiving the other two interventions (P = .02).
Both video interventions involved watching 30 minutes of sleep footage shown to each patient once before starting CPAP therapy. CPAP adherence was measured by downloaded data from PAP devices over the first 90 days of use.
The average age of the patients was 50 years, and they had moderate or severe sleep apnea, with mean apnea hypopnea indices ranging from 26.5 to 33.3 in the three study arms. The majority of patients had body mass indexes over 30.
Adherence to CPAP treatment is often poor, with many patients failing to use the device for even 4 hours per night, said Dr. Aloia, a psychologist at National Jewish Health in Denver. Many patients prescribed CPAP for OSA will undergo an educational component that may include watching a video of someone with OSA sleeping and having apneic events, he added. They often have “dramatic responses” to these videos, but then fail to positively change their own behavior.
“Many times we think that if our patient just knew what we know, he or she would use CPAP more, but there is evidence that doctors don’t take their medications any more than patients do, so it is not just a matter of education, it is a little bit deeper than that and it has to be personalized,” he said.
“The use of a personalized video is promising … we hope to present more data next year,” said Dr. Aloia, who has board certification in behavioral sleep medicine,
He noted that the video technique used may be jeopardized as more and more patients partake in home-based rather than lab-based sleep studies. That said, he also reported that the research team had to exclude several patients from the study because they had already viewed videos of themselves sleeping and snoring that had been recorded by their partners.
If the intervention proves effective, Dr. Aloia said he thinks it can be modified for use in home testing.
The study is supported by a grant from the National Heart, Lung, and Blood Institute. Dr. Aloia disclosed that he is a paid employee of Phillips, but that the study used both Phillips and ResMed CPAP devices.

Algorithm aims to tackle clozapine resistance
SAN DIEGO – The atypical antipsychotic drug clozapine is the standard of care for patients with treatment-resistant schizophrenia, but about half do not see an adequate response.
At the annual meeting of the American Psychiatric Association, Randall F. White, MD, presented an algorithm for clozapine-resistant patients intended to simplify and clarify a path forward. He also presented outcome data from a cohort of patients managed using this approach.
The algorithm recommends electroconvulsive therapy if there is inadequate response to clozapine alone or with fluvoxamine, which sometimes is used to boost clozapine serum level, especially in patients who are heavy smokers. If ECT fails to reduce symptoms or the patient refuses it, topiramate, aripiprazole, or sulpiride may be added to clozapine treatment, said Dr. White of the University of British Columbia, Vancouver.
And finally, if psychosis persists, certain patients should be offered cognitive-behavioral therapy with a psychologist trained in helping people with psychosis, Dr. White and his colleagues advise.
Dr. White said in an interview that the idea for a systematic approach to clozapine resistance came from clinical experience of the British Columbia Psychosis Program, which specializes in patients with severe schizophrenia and treatment resistance.
“About half of our patients come to us already on clozapine and aren’t getting better, so we needed to figure out a coherent approach to help them,” he said, noting that there is no current standard of care and that many “come to us already on four or five medications, and it can seem a bit random.”
When these patients are admitted, “we try to simplify their treatment and figure out what’s going on, and then offer ECT if appropriate,” he said.
Dr. White presented data from a cohort of patients assessed at the program between 2012 and 2017, of which 114 were taking clozapine at admission and had a diagnosis of schizophrenia or schizoaffective disorder.
To be considered clozapine-resistant, patients had to be taking 500 mg or more for at least 60 days, yet have persistent positive symptoms and moderate to severe impairment. Dr. White and his colleagues identified 20 patients with clozapine resistance. Of these, eight were offered ECT, and three accepted. At the time of discharge, 16 patients remained on clozapine with or without fluvoxamine. Four patients were treated with the recommended adjunctive agents aripiprazole or sulpiride and five with other agents.
Dr. White said the three agents recommended in the algorithm were determined by literature reviews, including meta-analyses of randomized trials. Several commonly used adjunctive agents to clozapine, including risperidone, were ruled out, for lack of evidence in this patient group.
Sulpiride, one of the drugs recommended in the algorithm, is not marketed in North America, and in Canada is accessible only by special arrangement. The evidence for aripiprazole, meanwhile, “is not stupendous,” Dr. White said, “but there’s a signal.”
The topiramate recommendation is based on results from a 2016 meta-analysis of randomized controlled trials. “Topiramate has a possible advantage of ameliorating metabolic problems,” Dr. White said, and the meta-analysis showed a significant effect size in improving positive and negative symptoms. However, he noted, on rare occasions, it has been seen to exacerbate psychosis.
Dr. White said few of the treatment-resistant patients seen in his program have had a course of ECT despite evidence of benefit. “Instead of ECT, they usually are put on multiple medications,” he said. “Admittedly, getting some of these patients to accept ECT isn’t easy.”
Because the program is designed to keep patients for 6 or more months as needed, “we have the luxury of time,” Dr. White said, to allow for the discontinuation of extraneous medicines and for an ECT trial if indicated.
“I know that in other hospitals, and other health care settings, they don’t have that – they have to figure out what to do quickly. And ECT is not the quickest treatment.”
Offering cognitive-behavioral therapy to people with psychosis is possible, he stressed, and supported by evidence from at least one study. “In this population, it’s challenging,” he acknowledged. “I don’t think I’d do it concurrently with ECT but as an alternative to or after ECT.”
Dr. White disclosed no conflicts of interest related to his research.

Dr. White said few of the treatment-resistant patients seen in his program have had a course of ECT despite evidence of benefit. “Instead of ECT, they usually are put on multiple medications,” he said. “Admittedly, getting some of these patients to accept ECT isn’t easy.”
Because the program is designed to keep patients for 6 or more months as needed, “we have the luxury of time,” Dr. White said, to allow for the discontinuation of extraneous medicines and for an ECT trial if indicated.
“I know that in other hospitals, and other health care settings, they don’t have that – they have to figure out what to do quickly. And ECT is not the quickest treatment.”
Offering cognitive-behavioral therapy to people with psychosis is possible, he stressed, and supported by evidence from at least one study. “In this population, it’s challenging,” he acknowledged. “I don’t think I’d do it concurrently with ECT but as an alternative to or after ECT.”
Dr. White disclosed no conflicts of interest related to his research.

Brain amyloid may herald decline in cognitively normal seniors
Cognitively normal seniors with brain amyloid experienced accelerated cognitive decline over as few as 3-4 years, compared with those who had no brain amyloid at baseline.
At 4 years’ follow-up, prodromal Alzheimer’s disease (AD) had developed in 32% of amyloid-positive people and 15% of the amyloid-normal people – a 16.9% difference. Extrapolating the limited 10-year data they collected, the authors projected that after a decade, 88% of the amyloid-positive cohort would have progressed, compared with 29% of the amyloid-normal cohort.
“This suggests that elevated brain amyloid may indicate a presymptomatic stage of disease rather than a risk factor for disease,” wrote Dr. Donohue of the University of Southern California, San Diego. “AD is a gradually progressive disorder that can be identified at the asymptomatic phase using biomarkers of amyloid.”
The study is a project of the Alzheimer’s Disease Neuroimaging Initiative, an ongoing natural history study assessing the clinical, imaging, genetics, and biomarkers of aging, from normal aging to early and late mild cognitive impairment, dementia, or AD.
This particular substudy tracked the association of baseline amyloid-beta 42 (AB42) and cognition among 445 patients, 202 of whom had elevated brain amyloid as measured by cerebrospinal fluid or brain imaging with florbetapir. They were followed for a mean of 3 years, although a limited number of patients had up to 10 years’ worth of data.
The primary endpoints were score changes on four cognitive batteries: the Preclinical Alzheimer Cognitive Composite, the Mini-Mental State Examination; the Clinical Dementia Rating Scale Sum of Boxes, and the Logical Memory Delayed Recall.
At baseline, mean patient age was 74 years, although amyloid-positive patients were slightly older (74.7 years vs. 73.4 years). The mean educational attainment was 16.4 years. Slightly more patients in the amyloid-positive group reported subjective memory complaints (25% vs. 22%). Significantly more had at least one APOE-e4 allele of the apolipoprotein E gene (42% vs. 16%). All were cognitively normal as measured by the four tests. A fifth measure, the Alzheimer’s Disease Assessment Scale 13-item cognitive subscale, was also within normal limits for both groups, but that was not included in the follow-up analysis.
In addition to showing AB42 deposits in the brain and/or decreased AB42 in cerebrospinal fluid (indicating increased binding in the brain), amyloid-positive patients also had significantly different levels of tau. CSF total tau was 76.8 pg/mL in the amyloid-positive group, compared with 59.4 pg/mL in the amyloid-normal group. CSF phosphorylated tau also was elevated in the amyloid-positive group (38.1 pg/mL vs. 26.5 pg/mL). Increased CSF tau is an indicator of neuronal injury.
The mean follow-up time was 3.9 years. At last contact, only four patients had died; 36% were lost to follow-up. Significantly more in the amyloid-positive group had progressed to Alzheimer’s dementia (13 vs. 7). Twenty in the positive group and nine in the negative group had started an antidementia medication.
At 4 years, the amyloid-positive group had declined significantly from baseline on all four cognitive measures, performing significantly worse than the amyloid-negative group on each. The amyloid-negative group, conversely, had either stayed steady or experienced nonsignificant change on the tests.
“The [Preclinical Alzheimer Cognitive Composite] assessment captures performance on tasks of episodic memory, orientation, and executive function – the prominent domains of AD-related cognitive decline,” the authors wrote. “This finding strengthens the link between elevated amyloid and the primary manifestations of AD. Individuals with normal amyloid remain free of AD-pattern impairment for many years.
“The longitudinal curves demonstrated that those participants with elevated amyloid were more likely to develop early symptoms consistent with prodromal amyloid within 6 years,” the researchers added.
The study also tracked biomarker changes in AB42, tau, and ventricular and hippocampal volume. These markers changed in both groups – although in each case, the changes associated with amyloid positivity were more pronounced.
Nevertheless, the biomarker data offered a more complex picture. “Measures of CSF tau, phosphorylated tau, and AB42 showed marked differences between groups at baseline,” the investigators noted. “Longitudinal change … was similar across groups, suggesting that they are sensitive to elevated amyloid but do not reflect cognitive and clinical decline once amyloidosis is established. Brain atrophy, as reflected by enlargement of ventricular size, showed change in participants with elevated amyloid. This trend is consistent with brain atrophy with normal aging that is aggravated in the presence of amyloid.”
The finding that AB42 can identify patients on the path to cognitive decline suggests that the protein is more than a risk factor for AD – it is, rather, a marker of presymptomatic disease.
“AD is a gradually progressive disorder that can be identified at the asymptomatic phase using biomarkers of amyloid,” Dr. Donohue and his colleagues said. If that view is accepted, it would change the way potential therapeutics are viewed, from agents that reduce the risk of disease to agents that actively manage disease, even if given presymptomatically.
“This view is important in weighing therapeutic options from a regulatory perspective and for an individual,” the investigators noted. “Accurate characterization of the potential progression of earliest symptoms may inform discussion of the utility of screening people for amyloid abnormalities, with or without effective therapeutic options.”

Despite a large, well-established body of evidence that cognitively normal older people can have brain amyloid without suffering memory loss, the protein does appear to be a harbinger of cognitive decline, Pieter Jelle Visser, MD, PhD, and Betty Tijms, PhD, said in an accompanying editorial (JAMA. 2017 Jun 13;317[22]:2285-7).
The natural history study of 445 elderly people showed consistent steady changes in cognition, as well as brain structure and function, over 4-10 years in those who were amyloid positive at baseline. This finding supports once again the idea that Alzheimer’s dementia is a slowly progressive disease with an extended preclinical phase but that amyloid and progression seem inextricably linked, wrote the two coauthors.
The study “provides further support for the hypothesis that amyloid pathology in cognitively normal individuals should be considered part of a progressive neurodegenerative disease. The results substantiate that amyloid aggregation in cognitively normal individuals is a harbinger of future cognitive decline,” which becomes evident only after extensive damage has occurred.
The work highlights Alzheimer’s long preclinical phase and may present a regulatory conundrum if any antiamyloid therapeutics are ever approved, Dr. Visser and Dr. Tijms said. Although the study demonstrates that amyloid pathology is most certainly not benign, many amyloid-positive elders never develop dementia, probably because they die of something else before becoming symptomatic. Thus, drugs that slow cognitive decline, effectively preventing dementia, may not be cost effective on a population basis.
“However, the other scenario of postponing treatment until an individual has developed cognitive impairments also has disadvantages, because at that stage, irreversible brain damage is so extensive that treatment becomes less effective,” Dr. Visser and Dr. Tijms noted. “This dilemma will require careful evaluation, because optimal patient management strategies will depend on the effectiveness, mechanism, cost, and adverse effects of treatment, as well as patient characteristics and preferences.”

Providers buck lipid recommendations in high-risk diabetes
SAN DIEGO – In the 3 months before their atherosclerotic cardiovascular event, 40% of high-risk patients with diabetes received no prescription for lipid-lowering therapy, researchers reported at the annual scientific sessions of the American Diabetes Association.
Underprescribing of high-intensity statins was also “particularly apparent for patients with diabetes mellitus alone, although rates improved somewhat over follow-up,” Sarah S. Cohen, PhD, of EpidStat Institute in Ann Arbor, Mich., said in a late-breaking poster. The findings highlight the need to educate providers and patients on the importance of addressing cardiovascular risk factors and disease in the diabetes setting, she wrote with her associates from the Mayo Clinic and Amgen.
Hypertension and dyslipidemia are classic companions of type 2 diabetes and “clear risk factors” for atherosclerotic cardiovascular disease (ASCVD), according to 2017 care guidelines from the American Diabetes Association.
“Diabetes itself confers independent risk,” the guidelines add. To characterize real-world use of lipid-lowering therapies in patients with diabetes, ASCVD, or both conditions, Dr. Cohen and her associates analyzed electronic medical records from more than 7,400 adults in Minnesota with new-onset type 2 diabetes mellitus or ASCVD, or incident ASCVD and existing diabetes between 2005 and 2012. During this period, about 4,500 patients were diagnosed with diabetes and another 570 patients with an existing diagnosis of diabetes were diagnosed with ASCVD based on incident myocardial infarction, unstable angina, stroke, or revascularization. An additional 2,300 patients had ASCVD alone.
Patients with existing diabetes and incident ASCVD tended to be in their 70s, two-thirds had used tobacco, 31% were overweight, and 54% were obese, the investigators found. Nonetheless, 40% of patients received no lipid-lowering therapy in the 3 months before the ASCVD event and 90% received no high-intensity statins. Three months after the event, 75% of patients were on lipid-lowering therapy and 64% were on moderate- or high-intensity statins. Patients with incident diabetes alone tended to be in their late 50s, about 60% had used tobacco, and two-thirds were obese. Only 34%, however, were prescribed moderate or high-intensity statins within 3 months after their diabetes diagnosis, and this proportion rose to just 46% at 2 years.
Diabetes is known to boost the risk of cardiovascular disease, but incident diabetes seldom triggered a prescription for lipid-lowering therapy in this cohort, the researchers concluded. Incident ASCVD was much more likely to elicit a prescription, but comorbid diabetes did not further improve the chances of receiving guideline-recommended therapy.
The ADA recommends screening for and treating modifiable CVD risk factors even in the prediabetes setting. For patients with clinical diabetes, providers should evaluate history of dyslipidemia, obtain a fasting lipid profile, and recommend lifestyle changes to address glycemic, blood pressure, and lipid goals, ADA guidelines state. In addition, comorbid diabetes and ASCVD merit high-intensity statin therapy, and diabetic patients with additional risk factors for CVD merit consideration of moderate- or high-intensity statin therapy, according to the recommendations.
The researchers lacked data on prescription fill rates, so they might have overestimated the proportion of patients taking lipid-lowering therapies, they noted. They also had no data on reasons for not prescribing lipid-lowering therapies.
Amgen and the National Institute on Aging provided funding. Dr. Cohen disclosed research funding from Amgen, which makes evolocumab, a lipid-lowering drug. She had no other conflicts of interest.

The researchers lacked data on prescription fill rates, so they might have overestimated the proportion of patients taking lipid-lowering therapies, they noted. They also had no data on reasons for not prescribing lipid-lowering therapies.
Amgen and the National Institute on Aging provided funding. Dr. Cohen disclosed research funding from Amgen, which makes evolocumab, a lipid-lowering drug. She had no other conflicts of interest.
AT THE ADA ANNUAL SCIENTIFIC SESSIONS
Key clinical point: Underprescribing of lipid-lowering therapies persists despite guidelines on their importance in patients with diabetes.
Major finding: About 40% of high-risk patients with diabetes were not prescribed lipid-lowering therapy in the 3 months before an atherosclerotic cardiovascular event.
Data source: Analyses of electronic medical records from 7,414 patients diagnosed with diabetes, atherosclerotic cardiovascular disease, or both between 2005 and 2012.
Disclosures: Amgen and the National Institute on Aging provided funding. Dr. Cohen disclosed research funding from Amgen, which makes evolocumab, a lipid-lowering drug. She had no other conflicts of interest.
Shulkin Outlines Veterans Choice Program 2.0
In testimony before the Senate Veterans Affairs Committee, VA Secretary David J. Shulkin, MD, outlined a vision for a revamped Veterans Choice Program that would allow veterans to access an integrated network of private health care providers for services not currently available at the VA. “We believe redesigning community care will result in a strong VA that can meet the special needs of our veteran population,” Shulkin told the committee. “Where VA excels, we want to make sure that the tools exist to continue performing well in those areas…. We need to move from a system where eligibility for community care is based on wait times and geography to one focused on clinical need and quality of care.”
During the hearing, Dr. Shulkin laid out the basic elements of the new Veterans Choice Program. The proposed changes include the following:
- Shifting from determining eligibility for community care based on wait times and geography to clinical need and quality of care;
- Streamlining process for veterans to access urgent care when they need it;
- Creating what VA is calling a "high performing integrated network,” which would include VA; other federal health care providers, such as military treatment facilities and IHS; academic affiliates; and community providers;
- Coordinating care across all providers; and
- Adopting recognized industry standards for quality, patient satisfaction, payment models, health care outcomes, and exchange of health information.
Over the past year, major veterans service organizations (VSOs), VA officials, the Commission on Care, and members of the House and Senate have worked together to develop the newly introduced Veterans Choice program. The major stakeholders came together at the hearing to “support the concept of developing an integrated network that combines the strength of the VA health care system with the best of community care to offer seamless access for enrolled veterans,” explained Adrian Atizado, the deputy national legislative director at Disabled American Veterans (DAV) in his prepared remarks.
The joint effort was in part a response to calls from some VA critics to provide veterans with unlimited choice to outside providers or to fully privatize veteran care.
In the hearing, Committee Chairman Johnny Isakson (R-GA) suggested that he would be willing to work with the VA on the changes to the Veterans Choice Program and was largely in support of the effort. “We need to see to it that the VA…is unleashed to provide the highest quality service that it can and make the decisions that it needs to make on the ground at the time we need to make them,” he reported in a release following the hearing. “We need to give them the funding, commitment and resources to be able to do that.”
At the hearing, VSOs praised the VA for its efforts to improve the Veterans Choice Program but still expressed frustration with problems that continue to dog the program. “The VFW [Veterans of Foreign Wars] has also heard from veterans that the breakdown in communication between VA, contractors and Choice providers often delays their care because their Choice doctors do not receive authorization to provide needed treatments,” reported Carlos Fuentes, VFW director national legislative services. “What is concerning is that veterans are left to piece together the entire story or else they do not.”
“While many veterans initially clamored for ‘more Choice’ as a solution to scheduling problems within the VA healthcare system, once this program was implemented, most have not found it to be a solution,” noted Jeff Steele, assistant director national legislative division of The American Legion. “Instead, they have found it to create as many problems as it solves.…What we have found over the past decade, directly interacting with veterans, is that many of the problems veterans encountered with scheduling appointments in VA are mirrored in the civilian community outside VA.

Relieving PTSD Symptoms May Cut Risk of Myocardial Infarction and Stroke
Women with severe posttraumatic stress disorder (PTSD) symptoms have a nearly 70% increase in the incidence of cardiovascular disease (CVD), according to a study by researchers from Harvard and Brigham and Women’s Hospital in Boston, Massachusetts, Columbia University in New York, and University of California in San Francisco.
The researchers analyzed data from 49,859 women in the Nurses’ Health Study II. Over 20 years, there were 552 confirmed cases of myocardial infarction or stroke.
Women with 6 to 7 symptoms of trauma and PTSD had the highest risk. Women with trauma but no PTSD symptoms had a 30% higher risk. When women who said illness was their worst trauma were excluded, the risk of CVD doubled among those with trauma and severe PTSD symptoms and increased by 88% in women with trauma and moderate PTSD symptoms.
Strikingly, the researchers also found that when the PTSD symptoms declined so did the CVD risk. The researchers note that CVD risk due to other well-known risk factors, such as smoking, increases with exposure duration declines once the risk factor is eliminated. In this study, for every 5 additional years PTSD symptoms lasted, the odds of CVD were 9% higher.
A “more nuanced understanding” of the role of health behaviors could add insight into how PTSD influences the risk of CVD, the researchers say. They point to studies that have found a link between PTSD and cardiotoxic behaviors such as smoking, drinking, and diet. Physiologic alterations that occur with PTSD symptoms also may play an important role, they suggest, such as changes in neuropeptide Y in response to stress, which might contribute to metabolic syndrome.
Citing “particularly intriguing” findings from a study that found symptoms eventually remitted in 44% of individuals with PTSD, the researchers say providing treatment shortly after PTSD symptoms begin could limit the risk of CVD and, potentially, other disease-related risk.

Unique Military and VA Nurse Collaboration to Teach and Learn
When military and VA nurses work side by side—learning from and teaching each other—they benefit and so do their patients. A “unique partnership” between the DoD and VA is proving that at Captain James A. Lovell Federal Health Care Center outside Chicago, Illinois.
The first of its kind facility serves nearly 67,000 active-duty military, military retirees, family members, and veterans. In an article for Health.mil News, U.S. Navy Lt. Nathan Aranas, an active-duty registered nurse (RN) and assistant nurse manager in the emergency department (ED), says, “We learn from local trauma, mental health, and pediatrics and birthing centers, exposing me more to how medicine outside of the military is practiced. It gives me a bigger perspective of how the rest of the country operates as a health care institution.”
Christine Barassi-Jackson, a VA civilian RN, nurse manager in the ED, says “having a combined organization is a great balance that pulls out the best parts of both the Navy and VA.” She leans on Aranas, the article says, to serve as an interpreter with some of the patients. “Knowing more of the Navy culture helps break down walls with the patients and other providers.” Aranas also believes that former active-duty patients may be more at ease with a uniformed nurse “because they understand the lingo.”
Overall, Aranas says, “It’s a great experience for young, active-duty clinicians to have."

Combo with daratumumab could be alternative to ASCT in MM
CHICAGO—Results of an open-label phase 1b study of daratumumab combined with carfilzomib, lenalidomide, and dexamethasone (KRd) in newly diagnosed multiple myeloma (MM) patients have shown the combination to be highly effective, with an overall response rate of 100%.
Ninety-one percent of patients achieved a very good partial response (VGPR) or better, and 43% achieved a complete response (CR) or better.
Investigators had hypothesized that rather than using autologous stem cell transplant (ASCT) to improve results of treatment with KRd, the combination could alternatively be improved by incorporating daratumumab into a KRd regimen.
Andrzej Jakubowiak, MD, of the University of Chicago Medical Center in Illinois, presented the findings of the MMY1001 study at the 2017 ASCO Annual Meeting (abstract 8000*).
“I think what was one of the more important developments in myeloma last year,” Dr Jakubowiak said, “was data from randomized studies showing that adding daratumumab to either lenalidomide and dexamethasone in the POLLUX study or bortezomib and dexamethasone, a proteasome inhibitor, in the CASTOR study, improves responses, depth of response, and . . . dramatically improved progression-free survival.”
“[W]e have now the rationale to potentially combine daratumumab with both an IMiD and proteasome inhibitor,” he explained, “which led to the development of this phase 1b study in which we combined daratumumab with KRd and evaluated tolerability and efficacy.”
Study design
Twenty-two transplant-eligible or -ineligible newly diagnosed MM patients were enrolled on the study.
Treatment duration was planned to be 13 cycles or less and patients had the option to move to transplant after 4 cycles.
They could have no clinically significant cardiac disease and echocardiogram was required prior to transplant.
The dosing schedule was the established dosing schema for daratumumab and KRd with 2 notable differences in the 28-day cycles.
First, the daratumumab dose was a split dose. So patients received 8 mg/kg on days 1-2 of cycle 1, 16 mg/kg a week on cycle 2, 16 mg/kg every 2 weeks on cycles 3 – 6, and every 4th week thereafter.
The second difference was carfilzomib dosing was a weekly regimen with escalation from 20 mg/m2 on day 1, cycle 1 to 70 mg/m2 on day 8 of cycle 1.
Lenalidomide (25 mg on days 1-21 of each cycle) and dexamethasone (40 mg/week) were the standard regimens for these drugs.
The primary endpoint was safety and tolerability. The secondary endpoint was overall response rate (ORR), duration of response, time to response, and infusion-related reactions (IRR).
The study also had an exploratory endpoint of progression-free survival (PFS).
Baseline characteristics
Patients were a median age of 59.5 years (range 34 – 74). About two thirds were younger than 65 and one third were between 65 and 75.
A little over half were male and most (86%) were white.
A little more than half (55%) had an ECOG score of 0, 41% were ECOG 1, and 5% were ECOG 2.
Patient disposition
As of the cutoff date of March 24, 8 of the 22 patients enrolled (36%) discontinued treatment: 1 due to an adverse event (AE), 1 due to progressive disease, and 6 patients (27%) proceeded to ASCT.
Dr Jakubowiak pointed out that response was censored at this point for patients who proceeded to transplant.
The median follow-up was 10.8 months (range, 4.0 – 12.5) and the median number of treatment cycles was 11.5 (range, 1.0 – 13.0).
“What is of interest to many of us,” Dr Jakubowiak said, “is that patients were escalated to the planned dose of 70 mg/m2 by cycle 2 except for 3 patients.”
Of the 3, 1 discontinued before day 1 of the second cycle due to toxicity, 1 had a dose reduction to 56 mg/m2 at day of the second cycle, and 1 escalated to 70 mg/m2 at day 8 of cycle 3.
Ultimately, all patients who remained on study were able to escalate to 70 mg/m2.
Safety
The hematologic treatment-emergent adverse events (TEAE) generally followed what has been observed in similar studies before, Dr Jakubowiak noted.
Hematologic TEAEs of all grades occurring in 30% or more of patients were lymphopenia (68%), thrombocytopenia (55%), anemia (46%), leukopenia (41%), and neutropenia (32%).
The most common non-hematologic TEAEs of all grades occurring in 30% of patients or more were diarrhea (73%), upper respiratory infection (59%) cough, constipation, and fatigue (50% each), dyspnea and insomnia (46%), nausea, rash, and back pain (41%), muscle spasm (36%), and vomiting, pain in extremity, hyperglycemia, and increased ALT (32%).
The most common grade 3/4 TEAEs were infrequent and many events had none of grade 3/4 severity.
The safety profile is consistent with what was previously reported for daratumumab or KRd, Dr Jakubowiak affirmed.
Serious TEAEs
Serious TEAEs occurred in 10 patients (46%), with many occurring in just 1 patient. Pulmonary embolism (PE) was the most frequent, occurring in 3 patients.
All patients were required to be on aspirin prophylaxis and 1 of the patients who had a PE discontinued therapy.
The number of patients with a serious TEAE reasonably related to an individual study drug were 3 (14%) for daratumumab, 5 (23%) for carfilzomib, 5 (23%) for lenalidomide, and 2 (9%) for dexamethasone.
The TEAEs of interest—tachycardia, congestive heart failure, and hypertension—occurred in a single patient each.
Overall, serious TEAEs were consistent with previous reports from KRd studies.
Echocardiogram assessment
Investigators conducted 30 systemic evaluations on the impact of this regimen on heart function. The investigators observed no change from baseline through the duration of treatment in patients’ left ventricular ejection fractions.
One patient developed congestive heart failure, possibly related to daratumumab or carfilzomib. This patient resumed treatment with a reduced carfilzomib dose, elected ASCT on study day 113, and ended treatment with a VGPR.
“In all,” Dr Jakubowiak said, “we feel that there is no apparent signal of adverse impact of the addition of daratumumab on cardiac function.”
Infusion times and reactions
Overall, IRRs occurred in 27% of the patients, “which appears lower than with previous daratumumab studies,” Dr Jakubowiak noted. And IRRs occurred more frequently during the first infusion than subsequent infusions.
The split-dose infusion time was very similar to that of second and subsequent cycles.
There were limited events related to infusions. All were grade 1 or 2 and most occurred in only a single patient.
Response rate
The median number of treatment cycles administered was 11.5 (range, 2.0 – 13.0). The best response was 100% PR or better, 91% achieved VGPR or better, 42% CR or better, and 29% a stringent CR.
The depth of response improved with duration of treatment. For example, the sCR rate increased from 5% after 4 cycles to 29% at the end of treatment.
PFS was an exploratory endpoint. One patient progressed at 10.8 months and the 12-month PFS rate was 94% with all patients alive.
Stem cell harvest and ASCT
“For many of us,” Dr Jakubowiak commented, “it’s also of interest how this regimen will impact stem cell harvest.”
Nineteen of 22 patients were deemed to be transplant eligible, and the median number of CD34+ cells collected from them was 10.4 x 106 cells/kg.
Patients had a median of 5 treatment cycles prior to stem cell harvest, and 14 (74%) had a VGPR or better prior to harvest.
The investigators believe stem cell yield was consistent with previous KRd studies.
Dr Jakubowiak commented that the deepening of response over time “is a phenomenon we think is important. . . . In all, the data from this small phase 1b study provide support for further evaluation of this regimen in newly diagnosed myeloma."
The study was funded by Janssen Research and Development, LLC.

Of the 3, 1 discontinued before day 1 of the second cycle due to toxicity, 1 had a dose reduction to 56 mg/m2 at day of the second cycle, and 1 escalated to 70 mg/m2 at day 8 of cycle 3.
Ultimately, all patients who remained on study were able to escalate to 70 mg/m2.
Safety
The hematologic treatment-emergent adverse events (TEAE) generally followed what has been observed in similar studies before, Dr Jakubowiak noted.
Hematologic TEAEs of all grades occurring in 30% or more of patients were lymphopenia (68%), thrombocytopenia (55%), anemia (46%), leukopenia (41%), and neutropenia (32%).
The most common non-hematologic TEAEs of all grades occurring in 30% of patients or more were diarrhea (73%), upper respiratory infection (59%) cough, constipation, and fatigue (50% each), dyspnea and insomnia (46%), nausea, rash, and back pain (41%), muscle spasm (36%), and vomiting, pain in extremity, hyperglycemia, and increased ALT (32%).
The most common grade 3/4 TEAEs were infrequent and many events had none of grade 3/4 severity.
The safety profile is consistent with what was previously reported for daratumumab or KRd, Dr Jakubowiak affirmed.
Serious TEAEs
Serious TEAEs occurred in 10 patients (46%), with many occurring in just 1 patient. Pulmonary embolism (PE) was the most frequent, occurring in 3 patients.
All patients were required to be on aspirin prophylaxis and 1 of the patients who had a PE discontinued therapy.
The number of patients with a serious TEAE reasonably related to an individual study drug were 3 (14%) for daratumumab, 5 (23%) for carfilzomib, 5 (23%) for lenalidomide, and 2 (9%) for dexamethasone.
The TEAEs of interest—tachycardia, congestive heart failure, and hypertension—occurred in a single patient each.
Overall, serious TEAEs were consistent with previous reports from KRd studies.
Echocardiogram assessment
Investigators conducted 30 systemic evaluations on the impact of this regimen on heart function. The investigators observed no change from baseline through the duration of treatment in patients’ left ventricular ejection fractions.
One patient developed congestive heart failure, possibly related to daratumumab or carfilzomib. This patient resumed treatment with a reduced carfilzomib dose, elected ASCT on study day 113, and ended treatment with a VGPR.
“In all,” Dr Jakubowiak said, “we feel that there is no apparent signal of adverse impact of the addition of daratumumab on cardiac function.”
Infusion times and reactions
Overall, IRRs occurred in 27% of the patients, “which appears lower than with previous daratumumab studies,” Dr Jakubowiak noted. And IRRs occurred more frequently during the first infusion than subsequent infusions.
The split-dose infusion time was very similar to that of second and subsequent cycles.
There were limited events related to infusions. All were grade 1 or 2 and most occurred in only a single patient.
Response rate
The median number of treatment cycles administered was 11.5 (range, 2.0 – 13.0). The best response was 100% PR or better, 91% achieved VGPR or better, 42% CR or better, and 29% a stringent CR.
The depth of response improved with duration of treatment. For example, the sCR rate increased from 5% after 4 cycles to 29% at the end of treatment.
PFS was an exploratory endpoint. One patient progressed at 10.8 months and the 12-month PFS rate was 94% with all patients alive.
Stem cell harvest and ASCT
“For many of us,” Dr Jakubowiak commented, “it’s also of interest how this regimen will impact stem cell harvest.”
Nineteen of 22 patients were deemed to be transplant eligible, and the median number of CD34+ cells collected from them was 10.4 x 106 cells/kg.
Patients had a median of 5 treatment cycles prior to stem cell harvest, and 14 (74%) had a VGPR or better prior to harvest.
The investigators believe stem cell yield was consistent with previous KRd studies.
Dr Jakubowiak commented that the deepening of response over time “is a phenomenon we think is important. . . . In all, the data from this small phase 1b study provide support for further evaluation of this regimen in newly diagnosed myeloma."

CHICAGO—Results of an open-label phase 1b study of daratumumab combined with carfilzomib, lenalidomide, and dexamethasone (KRd) in newly diagnosed multiple myeloma (MM) patients have shown the combination to be highly effective, with an overall response rate of 100%.
Ninety-one percent of patients achieved a very good partial response (VGPR) or better, and 43% achieved a complete response (CR) or better.
Investigators had hypothesized that rather than using autologous stem cell transplant (ASCT) to improve results of treatment with KRd, the combination could alternatively be improved by incorporating daratumumab into a KRd regimen.
Andrzej Jakubowiak, MD, of the University of Chicago Medical Center in Illinois, presented the findings of the MMY1001 study at the 2017 ASCO Annual Meeting (abstract 8000*).
“I think what was one of the more important developments in myeloma last year,” Dr Jakubowiak said, “was data from randomized studies showing that adding daratumumab to either lenalidomide and dexamethasone in the POLLUX study or bortezomib and dexamethasone, a proteasome inhibitor, in the CASTOR study, improves responses, depth of response, and . . . dramatically improved progression-free survival.”
“[W]e have now the rationale to potentially combine daratumumab with both an IMiD and proteasome inhibitor,” he explained, “which led to the development of this phase 1b study in which we combined daratumumab with KRd and evaluated tolerability and efficacy.”
Study design
Twenty-two transplant-eligible or -ineligible newly diagnosed MM patients were enrolled on the study.
Treatment duration was planned to be 13 cycles or less and patients had the option to move to transplant after 4 cycles.
They could have no clinically significant cardiac disease and echocardiogram was required prior to transplant.
The dosing schedule was the established dosing schema for daratumumab and KRd with 2 notable differences in the 28-day cycles.
First, the daratumumab dose was a split dose. So patients received 8 mg/kg on days 1-2 of cycle 1, 16 mg/kg a week on cycle 2, 16 mg/kg every 2 weeks on cycles 3 – 6, and every 4th week thereafter.
The second difference was carfilzomib dosing was a weekly regimen with escalation from 20 mg/m2 on day 1, cycle 1 to 70 mg/m2 on day 8 of cycle 1.
Lenalidomide (25 mg on days 1-21 of each cycle) and dexamethasone (40 mg/week) were the standard regimens for these drugs.
The primary endpoint was safety and tolerability. The secondary endpoint was overall response rate (ORR), duration of response, time to response, and infusion-related reactions (IRR).
The study also had an exploratory endpoint of progression-free survival (PFS).
Baseline characteristics
Patients were a median age of 59.5 years (range 34 – 74). About two thirds were younger than 65 and one third were between 65 and 75.
A little over half were male and most (86%) were white.
A little more than half (55%) had an ECOG score of 0, 41% were ECOG 1, and 5% were ECOG 2.
Patient disposition
As of the cutoff date of March 24, 8 of the 22 patients enrolled (36%) discontinued treatment: 1 due to an adverse event (AE), 1 due to progressive disease, and 6 patients (27%) proceeded to ASCT.
Dr Jakubowiak pointed out that response was censored at this point for patients who proceeded to transplant.
The median follow-up was 10.8 months (range, 4.0 – 12.5) and the median number of treatment cycles was 11.5 (range, 1.0 – 13.0).
“What is of interest to many of us,” Dr Jakubowiak said, “is that patients were escalated to the planned dose of 70 mg/m2 by cycle 2 except for 3 patients.”
Of the 3, 1 discontinued before day 1 of the second cycle due to toxicity, 1 had a dose reduction to 56 mg/m2 at day of the second cycle, and 1 escalated to 70 mg/m2 at day 8 of cycle 3.

Assessing the risks associated with MRI patients with a pacemaker or defibrillator
Clinical Question: What are the risks of nonthoracic MRI in patients with pacemakers or implantable cardioverter-defibrillators (ICD) who are not preapproved by the Food and Drug Administration for MRI scanning?
Background: Implantable cardiovascular devices could suffer heating in MRI magnetic fields leading to cardiac thermal injury and changes in pacing properties. The FDA approves “MRI-conditional devices” deemed safe for MRI, but up to six million patients worldwide (and two million in the United States) have non–MRI conditional devices.
Setting: U.S. Centers participating in the MagnaSafe registry.
Synopsis: Adults with non–MRI conditional pacemakers (1000 cases) or ICDs (500 cases) implanted in the thorax after 2001 were scanned with nonthoracic MRI at 1.5 Tesla. Patients with abandoned or inactive leads, other implantable devices, and low batteries and pacing-dependent patients with ICDs were excluded.
Devices were interrogated before each MRI and set to either no pacing or asynchronous pacing with all tachycardia and bradycardia therapies deactivated. Primary endpoints included immediate death, generator or lead failure, loss of capture in paced patients, new arrhythmia, and generator reset.
No patients suffered death or device or lead failure. Six patients developed self-terminating atrial arrhythmias, while an additional six had partial pacemaker electrical reset. Several devices had detectable changes in battery voltage, lead impedance, pacing threshold, and P- or R-wave amplitude without evident clinical significance. Multiple MRIs caused no increase in adverse outcomes. This study suggests that patients with non–MRI conditional devices may be at low risk from nonthoracic imaging if appropriately screened with temporary pacemaker function modification before MRI.
Bottom Line: Appropriately screened and prepared patients with non–MRI conditional thoracic pacemakers or ICDs may be at low risk for complications from nonthoracic MRI at 1.5 Tesla.
