Mydayis approved for teens, adults with ADHD
The Food and Drug Administration has approved a once-a-day treatment for patients aged 13 years and older with ADHD, Shire announced June 20 in a press release.
The approval of Mydayis was based on results from 16 clinical studies evaluating the medication in more than 1,600 adolescents (aged 13-17 years) and adults with attention-deficit/hyperactivity disorder. In the placebo-controlled clinical studies, Mydayis significantly improved symptoms of ADHD, as measured by the ADHD-RS-IV and the Permanent Product Measure of Performance (PERMP), in adults and adolescents. Improvement on the PERMP reached statistical significance beginning at 2 or 4 hours post dose and lasting up to 16 hours post dose.
The medication, an amphetamine product, consists of three different types of drug-releasing beads.
“With this approval, we hope to help patients who need a once-daily treatment option,” Flemming Ornskov, MD, MPH, said in a press release. Dr. Ornskov is CEO of Shire.
It is estimated that 4.4% of adults have ADHD in the United States, and 50%-66% of children with ADHD may continue to have symptoms of the disorder as adults.
Mydayis will be commercially available in the United States in the third quarter of 2017.

How to prevent secondary posttraumatic knee osteoarthritis
LAS VEGAS – A variety of evidence-based strategies are available for preventing posttraumatic knee osteoarthritis (KOA) in patients who have already sustained an anterior cruciate ligament (ACL) injury. And they’re generally ignored, according to May Arna Risberg, PhD.
“We have a lot of knowledge. We can use secondary prevention strategies. And here I think we, as physical therapists, physicians, and orthopedic surgeons, are doing a lousy job because we are sending these ACL-injured patients back to sports before they have normalized knee function and quadriceps strength,” said Dr. Risberg, professor of sports medicine at the Norwegian School of Sport Sciences in Oslo.
With no proven disease-modifying therapy for KOA available to date, secondary prevention of posttraumatic KOA is worthy of high-priority status, she said at the World Congress on Osteoarthritis. An estimated 250,00 ACL injuries occur annually in the United States, and up to one-half of affected patients, most of whom are young, active people, will experience a second ACL rupture within the first few years after undergoing their initial reconstruction. This second ACL injury greatly increases their risk of developing posttraumatic KOA within 15-20 years, while they are still relatively young, she said.
Moreover, if the second ACL injury involves meniscus surgery, the 5-year risk of posttraumatic KOA roughly triples to up to 48%.
She highlighted a few effective strategies for preventing posttraumatic KOA in patients who already have an ACL injury.
Avoid reinjury
Dr. Risberg was senior author of a recent report from the prospective Delaware-Oslo Cohort Study involving 106 athletes who underwent ACL reconstruction following injury in what she termed level I sports. These are sports that entail lots of pivoting, jumping, and hard cutting, such as basketball, soccer, and handball.
In the first 2 years after ACL repair, 30% of patients who returned to participation in a level 1 sport experienced an ACL reinjury, compared with just 8% who opted for a lower-level sport. Athletes who returned to a level 1 sport had an adjusted 4.3 times greater ACL reinjury rate than those who didn’t, Dr. Risberg noted at the congress sponsored by the Osteoarthritis Research Society International.
The good news is that this sharply increased reinjury risk was mitigated if return to a level 1 sport was delayed for at least 9 months post surgery and if the patient had regained quadriceps strength comparable to the uninjured side. For every month that return to sport was delayed out until 9 months post ACL reconstruction, the knee reinjury rate was reduced by 51% (Br J Sports Med. 2016;50:804-8).
In a meta-analysis by other investigators of 12 studies including 5,707 participants, weakness of the knee extensor muscles was independently associated with a 1.65 times increased risk of developing KOA (Osteoarthritis Cartilage. 2015 Feb;23[2]:171-7).
Attend to BMI
A discussion of the importance of maintaining a healthy body weight is an important aspect of patient education for athletes with knee injuries. In a cohort study of 988 patients who underwent primary ACL reconstruction, being overweight or obese was associated with a significantly increased risk of subsequent meniscal tears and chondral lesions (Am J Sports Med. 2015 Dec;43[12]:2966-73).
Also, it’s well established that obesity is a risk factor for knee OA, and Canadian investigators have shown that young athletes with a sports-related intra-articular knee injury were 3.75 times more likely to be overweight or obese 3-10 years post injury, compared with matched uninjured controls (Osteoarthritis Cartilage. 2015 Jul;23[7]:1122-9).
Consider prehabilitative exercise training
Dr. Risberg and coinvestigators have reported that preoperative quadriceps muscle strength deficits are predictive of impaired knee function, as measured by the Cincinnati Knee Score 2 years post surgery. She said she believes ACL reconstruction shouldn’t be done until quadriceps muscle strength is at least 80% of that in the uninjured limb (Br J Sports Med. 2009 May;43[5]:371-6). She and her coinvestigators have published the details of a 5-week progressive exercise therapy program in which they have shown results in significantly improved early postoperative knee function (J Orthop Sports Phys Ther. 2010 Nov;40[11]:705-21). They now try to have patients complete the twice-weekly, 5-week program before final decisions are reached regarding whether to have ACL reconstruction.
Test all before okaying return to sport
It’s important to know if patients who have undergone ACL reconstruction have gotten full knee function back before determining if they’re ready for full-on sports participation. In the Delaware-Oslo Cohort Study, patients who delayed their return until at least 9 months after surgery and passed the return-to-sports test had a 5.6% reinjury rate within 2 years, while those who failed the return-to-sports criteria had a 38.2% ACL reinjury rate.
The return-to-sports testing utilized in this study entailed isokinetic quadriceps strength testing, the single hop leg test, the 14-item self-rated Knee Outcome Survey–Activities of Daily Living Scale, and a self-rated Global Rating Scale of perceived function on a 0-100 scale. To be cleared for return to sports, a patient had to demonstrate having regained at least 90% of quadriceps muscle strength and hop performance along with scoring in the normative range on both of the self-rating instruments.
Surgical vs. nonsurgical treatment of ACL rupture
The evidence on this score is conflicting, according to Dr. Risberg. While most physical therapists believe ACL reconstruction doesn’t protect against later development of KOA, as reflected in a meta-analysis of published studies (J Bone Joint Surg Am. 2014 Feb 19;96[4]:292-300), a more recent retrospective comparison of 964 patients with an isolated ACL tear and an equal number of matched controls concluded that patients treated nonoperatively were six times more likely to have been diagnosed with KOA and 16.7 times more likely to have undergone total knee replacement at a mean follow-up of 13.7 years than were those treated with ACL reconstruction (Am J Sports Med. 2016 Jul;44[7]:1699-707).
Dr. Risberg’s fellow panelist Jackie Whittaker, PhD, said that, as long as quadriceps muscle strengthening is a priority, it makes sense to strengthen the hamstring as well, particularly if the ACL reconstruction utilized the hamstring tendon.
“Also, I would add that it’s important to develop a relationship with these ACL-injured people, who are often very young. Preventing a disease that they’re going to get 20 years later isn’t a priority for them. You need to develop that relationship and build it up over time. Helping them set realistic expectations is very important. And we need to do what we can to help them find some sort of competitive outlet. A lot of these kids were very competitive, and now they’ve had an injury and can’t compete. They don’t want to go back to playing just any sport. They want to be able to be competitive, and if you don’t help them find another way to express that, they sort of give up on physical activity altogether,” according to Dr. Whittaker of the University of Alberta in Edmonton.
Dr. Risberg and Dr. Whittaker reported having no financial conflicts of interest.

EXPERT ANALYSIS FROM OARSI 2017
Newly Diagnosed Patients with Epilepsy Need Psychiatric Evaluation
Every patient who is initially diagnosed with epilepsy should also be evaluated for coexisting psychiatric problems, according to Andres Kanner with the Department of Neurology, University of Miami School of Medicine. Kanner noted that psychiatric comorbidities often existed in patients before they were diagnosed with a seizure. That, coupled with the fact that drug therapy and surgery for epilepsy often cause psychiatric symptoms, is part of the justification for conducting these evaluations.

Similar Adverse Effects Reported in Generic vs Brand AEDs
Although a recent analysis of adverse effects (AEs) found differences between AEs reported for generic versions compared with brand name versions of the 3 common antiepileptic drugs (AEDs), when approved generic formulations were compared to unapproved generics, reporting odds ratios were similar for authorized generic AEDs and generic AEDs. The researchers concluded that the differences were the result of perception biases. There were differences in drug AE reports of suicide and suicide ideation between authorized generic and brand name drugs that could not be explained by bias.

Stress Linked to Recurrent Seizures in Adults
The likelihood of experiencing a recurrent seizure is closely linked to a person’s stress level, according to a recent study that looked at 52 individuals with a single unprovoked seizure and 29 with newly diagnosed epilepsy. The researchers, who looked at adult residents in low-income areas of Northern Manhattan and Harlem, New York City, found that generalized anxiety disorder increased the risk of a recurrent seizure threefold. In a second analysis, a mood disorder more than doubled the risk of a recurrent seizure.

SPRINT: Intensive BP control cut cardiovascular risk in patients with prediabetes
SAN DIEGO – Treating systolic hypertension to a target of 120 mm Hg instead of 140 mm Hg significantly reduced the rate of cardiovascular events in high-risk patients with prediabetes, according to a post-hoc analysis of the multicenter, randomized, controlled, open-label Systolic Blood Pressure Intervention Trial (SPRINT).
Thus, prediabetes did not undercut the cardiovascular benefits of intensive systolic blood pressure (SBP) control in older, high-risk, hypertensive patients, Adam P. Bress, PharmD, MS, and his associates concluded in a late-breaking poster presented at the annual scientific sessions of the American Diabetes Association.
In contrast, intensive SBP control did not prevent cardiovascular events, compared with standard control among diabetic patients in the randomized, nonblinded ACCORD BP trial (N Engl J Med. 2010; 362:1575-85).
To help clarify SBP targets for prediabetic individuals, Dr. Bress and his associates parsed cardiovascular outcomes in SPRINT based on baseline fasting serum glucose (FSG) levels. More than 5,400 normoglycemic (average FSG, 91 mg per dL) patients and more than 3,800 prediabetic (average FSG, 110 mg per dL) patients were followed for a median of 3.3 years, after which 101 (1.6%) prediabetic intensive control patients and 144 (2.3%) prediabetic standard control patients experienced the combined primary endpoint (HR, 0.7; 95% confidence interval, 0.5-0.9). The hazard ratio for normoglycemic patients was similar (0.9) and approached statistical significance.
Intensive SBP control also was associated with lower rates of individual cardiovascular outcomes and all-cause mortality, compared with standard control in both normoglycemic and prediabetic patients, Dr. Bress and his associates reported. Wide confidence intervals precluded statistical significance for most individual outcomes, but intensive control was associated with a significantly lower risk of all-cause mortality in normoglycemic patients (0.7% vs. 1.4% with standard control; HR, 0.7; 95% CI, 0.5-0.9).
Serious adverse events affected about 37% of patients in all subgroups. Hypotension, syncope, bradycardia, and electrolyte abnormalities were slightly more common in the intensive control groups than the standard control groups, regardless of baseline FPG levels.
SPRINT was sponsored by the National Heart, Lung, and Blood Institute. The National Institute on Aging, the National Institute of Diabetes and Digestive and Kidney Diseases, the National Institute of Neurological Disorders and Stroke, and Wake Forest University Health Sciences provided additional support. Dr. Bress disclosed research support from Novartis and the National Institutes of Health.
SAN DIEGO – Treating systolic hypertension to a target of 120 mm Hg instead of 140 mm Hg significantly reduced the rate of cardiovascular events in high-risk patients with prediabetes, according to a post-hoc analysis of the multicenter, randomized, controlled, open-label Systolic Blood Pressure Intervention Trial (SPRINT).
Thus, prediabetes did not undercut the cardiovascular benefits of intensive systolic blood pressure (SBP) control in older, high-risk, hypertensive patients, Adam P. Bress, PharmD, MS, and his associates concluded in a late-breaking poster presented at the annual scientific sessions of the American Diabetes Association.
In contrast, intensive SBP control did not prevent cardiovascular events, compared with standard control among diabetic patients in the randomized, nonblinded ACCORD BP trial (N Engl J Med. 2010; 362:1575-85).
To help clarify SBP targets for prediabetic individuals, Dr. Bress and his associates parsed cardiovascular outcomes in SPRINT based on baseline fasting serum glucose (FSG) levels. More than 5,400 normoglycemic (average FSG, 91 mg per dL) patients and more than 3,800 prediabetic (average FSG, 110 mg per dL) patients were followed for a median of 3.3 years, after which 101 (1.6%) prediabetic intensive control patients and 144 (2.3%) prediabetic standard control patients experienced the combined primary endpoint (HR, 0.7; 95% confidence interval, 0.5-0.9).

Surgeon volume tied to mitral valve surgery outcomes
CHICAGO – A total annual surgeon volume of fewer than 25 operations was associated with increased 1-year mortality and reoperation rates, according to a study presented at the 2017 American Association for Thoracic Surgery Centennial.
Improvements in repair rates, survival, and freedom from reoperation increased with increasing surgeon case volumes, Joanna Chikwe, MD, and her colleagues at the Icahn School of Medicine at Mount Sinai, New York, stated.
The researchers compared repair rates, long-term survival, and risk of postrepair reoperation in patients with degenerative disease according to total annual surgeon volume, which was defined as any mitral valve operation for any cause during the study period. The study was simultaneously published in the Journal of the American College of Cardiology (2017 May 16;69[19]:2397-406).
Mitral valve repair is the preferred treatment, compared with valve replacement, for the treatment of severe mitral valve regurgitation in patients who have degenerative valve disease with mitral valve prolapse, and both U.S. and European guidelines strongly recommend valve repair whenever possible, according to Dr. Chikwe and her colleagues.
But, “mitral valve replacement unfortunately remains relatively common in patients with degenerative valve disease,” they stated.
A total of 313 surgeons from 41 institutions met the study eligibility criteria, according to the researchers. They performed a median of 10 mitral valve operations per year (range, 1-230). The median annual institutional mitral valve volume was 59 mitral valve operations, ranging from a minimum of 6 to a maximum of 310 operations. Repair rates for primary mitral valve operations for any cause at all 41 institutions varied from 15% to 83%, and repair rates for degenerative mitral valve operations varied from 25% to 100%.
In the study cohort, surgeons with a total annual volume of less than 25 operations carried out 25% of procedures.
After multivariable adjustment, total annual surgeon volume was independently associated with the probability of mitral valve repair. The chance of repair increased significantly by 13% for every 10-case increment in total annual surgeon volume (P less than .001).
In addition, compared with patients operated on by surgeons with a total annual surgeon volume of 10 or fewer operations, patients operated on by surgeons with a total annual surgeon volume of greater than 50 operations were more than three times as likely to undergo mitral valve repair rather than replacement.
A total annual surgeon volume of less than 25 operations was associated with lower mitral valve repair rates and with increased 1-year mortality and mitral valve reoperation rates. Improvements in repair rates, survival, and freedom from reoperation increased with increasing surgeon case volumes.
After 1 year of repair or replacement, the actuarial survival of patients with degenerative mitral valve disease who were operated on by surgeons performing greater than 50 operations per year was 97.8%, compared with 94.1% for patients operated on by surgeons performing less than or equal to 10 operations a year.
Compared with replacement, mitral repair was significantly associated with better survival, but total annual surgeon volume still remained a significant independent predictor (P less than .001). In addition, for those patients who underwent mitral valve repair, total annual surgeon volume was a significant independent predictor of late death.
The results are important, the investigators noted, given that the median number of mitral valve operations performed annually by individual surgeons in the United States was five, according to an analysis of the Society of Thoracic Surgeons database – and that, in New York state, most surgeons actually performed less than one mitral operation per month.
There were significant differences seen in the patient characteristics across surgeons’ case volume groups. The prevalence of congestive heart failure was significantly higher in patients operated on by surgeons with lower volumes, and the proportion of patients undergoing urgent surgery was also significantly higher for lower-volume surgeons.
“This leads to a double jeopardy, where sicker patients are adversely affected by the lower repair rates and poorer outcomes seen with lower-volume surgeons, and it underscores the need to refer the highest-risk patients to high-volume surgeons,” said Dr. Chickwe and her colleagues.
However, “even among high-volume surgeons, there was an observed variability of degenerative disease repair rates, ranging from 19% to nearly 100%,” they added. “This finding reflects that surgeon volume is not the only factor for better outcomes, and it emphasizes the need for more transparency of surgeon-related factors and outcomes of degenerative mitral valve surgery for patients and referring cardiologists.
“Considering that there was an incremental improvement in survival and probability of repair with increasing volume over 25 operations, one could make the argument that a minimum volume target of 50, or even more, operations would be optimal,” the researchers noted. “Developing more very high-volume surgeons experienced in mitral valve repair would likely be particularly beneficial for patients with complex but repairable mitral valve disease, and for asymptomatic patients whose repair feasibility would optimally approach 100%.”

Flashback to 2013 and the attempt to repeal the SGR formula
This month, our “Flashback” article highlights Congress’s long-term attempt to repeal the Sustainable Growth Rate formula for physician reimbursement and base our payments on patient health outcomes. Although the Medicare Access and Quality Improvement Act of 2013 (highlighted in our 2013 article) sponsored by Rep. Michael Burgess and passed unanimously in the House of Representatives did not become law, it did set the stage for the passage of H.R.2 – the Medicare Access and CHIP Reauthorization Act of 2015 (MACRA). Also sponsored by Rep. Burgess and passed with bipartisan support, MACRA has now become the foundation for our transition from fee-for-service reimbursement to value-based care.
In just 2 short years, we have all become familiar with terms like MIPS (Merit-based Incentive Payment System) and APMs (Alternative Payment Models). These two methods of reimbursement will become the backbone of a growing percentage of our revenue going forward. Gastroenterologists should embrace these programs and work to find our unique position in the health care value chain.
Do not reject the transition to value. Medicine is no different from most other industries in which value for the consumer is the major driver of business model change. Although physicians pride themselves on practicing quality medicine, quality cannot be our only focus. The cost of the services we provide must also be considered. Together, higher quality and lower cost drive value.
Our focus on cost should not only be directed at the specific services we ourselves provide, but should also be aimed at the total cost of care for the population of patients we are serving. We must be able to demonstrate to those who are taking the risk for payment that the real value of our services lies in improving the health and lowering the overall cost of care for a population of patients.

This month, our “Flashback” article highlights Congress’s long-term attempt to repeal the Sustainable Growth Rate formula for physician reimbursement and base our payments on patient health outcomes. Although the Medicare Access and Quality Improvement Act of 2013 (highlighted in our 2013 article) sponsored by Rep. Michael Burgess and passed unanimously in the House of Representatives did not become law, it did set the stage for the passage of H.R.2 – the Medicare Access and CHIP Reauthorization Act of 2015 (MACRA). Also sponsored by Rep. Burgess and passed with bipartisan support, MACRA has now become the foundation for our transition from fee-for-service reimbursement to value-based care.
In just 2 short years, we have all become familiar with terms like MIPS (Merit-based Incentive Payment System) and APMs (Alternative Payment Models). These two methods of reimbursement will become the backbone of a growing percentage of our revenue going forward. Gastroenterologists should embrace these programs and work to find our unique position in the health care value chain.

DURATION-8: Exenatide/dapagliflozin efficacy holds up at 1 year
SAN DIEGO – A year of treatment with once-weekly exenatide and once-daily dapagliflozin significantly outperformed either therapy alone for patients whose type 2 diabetes was uncontrolled on metformin, investigators reported at the annual scientific sessions of the American Diabetes Association.
At week 52, hemoglobin A1c, fasting and 2-hour postprandial glucose levels, body weight, and systolic blood pressure improved significantly more in the exenatide/dapagliflozin arm than in the dapagliflozin/placebo arm in the multicenter randomized, double-blind, phase III DURATION-8 trial, Cristian Guja, MD, said in a late-breaking poster. Exenatide/dapagliflozin also topped dapagliflozin/placebo on glycemic outcomes but not on measures of body weight or blood pressure.
Exenatide (Byetta, AstraZeneca) is a glucagon-like peptide–1 (GLP-1) receptor agonist, while dapagliflozin (Farxiga, AstraZeneca) is a sodium-glucose cotransporter–2 (SGLT-2) inhibitor. For the study, Dr. Guja and coinvestigators randomly assigned patients with type 2 diabetes and HbA1c levels of 8%-12% despite metformin therapy to receive one of three regimens: exenatide once weekly (2-mg subcutaneous injection) plus dapagliflozin (10-mg oral tablet), exenatide with daily placebo tablets, or dapagliflozin with weekly injected placebo. Between weeks 8 and 28, patients received rescue therapy with basal insulin according to progressively stricter fasting plasma glucose criteria that culminated at 200 mg/dL. From weeks 36 to 52, patients received rescue therapy if their HbA1c level exceeded 8%.
A total of 695 patients were randomized to one of the three study arms, and 564 (81%) patients completed 1 year of treatment. Improvements at 1 year resembled those at week 28. Between baseline and week 52, HbA1c levels fell by an average of 1.75% in the exenatide/dapagliflozin arm, 0.37% more than with exenatide/placebo (P less than .01) and 0.52% more than with dapagliflozin/placebo (P less than .01). Combination therapy also cut mean fasting plasma glucose levels by 63 mg/dL, which was 18 mg/dL more than with exenatide/placebo (P less than .001) and 23 mg/dL more than with dapagliflozin/placebo (P less than .001). Two-hour postprandial glucose levels dropped by 82 mg/dL with dual therapy, 18.4 mg/dL more than with exenatide/placebo (P less than .01), and 23 mg/dL more than with dapagliflozin/placebo (P less than .001). Recipients of dual therapy also lost an average of 3.3 kg over a period of 1 year and cut their systolic blood pressure by a mean of 4.5 mm, reductions that significantly exceeded those with exenatide/placebo but not with dapagliflozin/placebo.
Proportionally fewer patients needed rescue therapy in the dual-treatment arm (27%), compared with the exenatide/placebo arm (32%) or the dapagliflozin/placebo arm (38%). Most patients needed rescue therapy because their HbA1c levels exceeded 8%, not because their fasting glucose level exceeded 200 mg/dL, Dr. Guja said.
Combination therapy was “well tolerated, with no unexpected adverse events,” Dr. Guja reported. At 52 weeks, the groups had similar rates of serious adverse events, gastrointestinal adverse events, and adverse events leading to treatment discontinuation. In each arm, about 4% of patients stopped treatment because of adverse events. Dual therapy was associated with slightly higher rates of injection-site nodules (9%) and headaches (6%), compared with exenatide or dapagliflozin alone. There were no cases of severe hypoglycemia or acute renal failure. Glomerular filtration rates dropped by an average of 2 mL/ min per 1.73 m2 after 1 year of exenatide/dapagliflozin, by 1.2 mL/min per 1.73 m2 with exenatide/placebo, and by 0.8 mL/min per 1.73 m2 with dapagliflozin/placebo.
Baseline characteristics were similar between groups in DURATION-8. Glycated hemoglobin levels averaged 9.3% in each arm, fasting plasma glucose averaged 195-198 mg/dL, body mass index averaged 32-33 kg/m2, and systolic blood pressure averaged 130 mm Hg.
