Promising outcomes of thrombolysis for caval extension of iliofemoral DVT
CHICAGO – Caval extension of an acute iliofemoral deep vein thrombosis paradoxically portends better treatment outcomes than does thrombolysis of a DVT without involvement of the inferior vena cava, according to Rabih A. Chaer, MD, professor of surgery at the University of Pittsburgh.
This finding from a retrospective analysis of the University of Pittsburgh experience might seem counterintuitive. After all, caval extension clearly indicates a greater clot burden. One possible explanation: Clearing a thrombus from a large vessel, such as the inferior vena cava (IVC), provides an added protective effect. Also, since the caval segments don’t have valves – their flow is based upon negative pressure in the chest – they may not contribute as much to postthrombotic morbidity to the same extent as do thrombosed iliofemoral segments, Dr. Chaer speculated at a symposium on vascular surgery sponsored by Northwestern University.
The impetus for Dr. Chaer and coinvestigators to review the Pittsburgh experience was a lack of clarity in the literature as to the effect IVC thrombosis has on thrombolysis outcomes in patients with acute iliofemoral DVT. Even though caval thrombus extension is present in up to 22% of patients with iliofemoral DVT, current guidelines issued by the American College of Chest Physicians, the American Heart Association, and the Society for Vascular Surgery don’t address the distinction between iliofemoral DVT with and without IVC extension in regard to the occurrence of postthrombotic syndrome (PTS), the most common complication of DVT.
The incidence of PTS in patients whose iliofemoral DVT is treated by anticoagulation and compression alone is up to 50%. Mounting evidence indicates that catheter-directed thrombolysis and pharmacomechanical thrombolysis aimed at achieving early thrombus removal and symptom relief help maintain valvular competence and reduce the risk of PTS, the surgeon noted.
PTS is diagnosed using the validated Villalta scale, which incorporates clinical signs including pain on calf compression, skin edema and redness, and ulcers, as well as symptoms such as leg cramping, heaviness, itching, and paresthesia.
The Pittsburgh series included 102 consecutive patients treated with various combinations of catheter-directed or pharmacomechanical thrombolysis in 127 limbs with acute iliofemoral thrombosis. In 46 patients, the thrombus extended into the IVC, all the way up to the renal veins in most cases.
The groups with and without caval extension were similar in terms of age and prevalence of malignancy, hypercoagulable state, and clot age. However, a history of previous DVT was significantly more common in the group with IVC thrombus. Also, more than 60% of patients with caval extension got an IVC filter, a rate more than 10-fold greater than that in patients without caval extension.
In this series, caval thrombosis had no effect on the technical success of thrombolysis. The technical success rate –defined as at least 50% clot lysis – was 89% in both groups. Rates of recurrent DVT within 30 days were similar in the two groups as well: 11% in the caval thrombosis group and 14% in the noncaval group. At 2 years postintervention, 77%-78% of patients in both groups remained free of DVT recurrence. The rate of PTS – defined by a Villalta score of 5 or more – at 2 years was 34% in the noncaval group, which was significantly higher than the 11% rate in patients with IVC thrombus extension. Ultrasound-identified valve reflux was present in 51% of the noncaval group at 2 years, compared with 51% of the noncaval group.
On multivariate analysis, incomplete clot lysis was associated with nearly a 23-fold increased risk of recurrent DVT and a 5.6-fold increased risk of PTS. Caval involvement was independently associated with a 78% reduction in PTS risk.
The Society for Vascular Surgery’s guidelines recommend pharmacomechanical thrombolysis over catheter-directed thrombolysis if the expertise is available. The Pittsburgh experience speaks to the worth of that recommendation.
“Pharmacomechanical techniques can be advantageous. They can expedite the lysis process by clearing most of the clot. In our series, 20 patients were treated with pharmacomechanical techniques in a single session,” Dr. Chaer noted.
The use of IVC filters in the setting of caval extension of iliofemoral DVT is controversial, according to the surgeon: A thrombus that gets trapped in the filter is tough to remove, precluding successful recanalization.
“One-third of the patients in our series got a filter, but we’ve become more conservative nowadays. We don’t use filters anymore. But I think those patients who might benefit from an IVC filter are those who present with a PE [pulmonary embolism], because that’s telling you they might develop another PE, as well as those patients in whom pharmacomechanical thrombolysis is anticipated because we’ve seen that those patients are also more likely to develop a PE,” he said.
The University of Pittsburgh study on the effect of IVC thrombus extension has been published (J Vasc Surg Venous Lymphat Disord. 2016 Oct;4[4]:385-91).

Group Education Is Effective Migraine Intervention
Group education on headache evaluation and lifestyle management has potential as an effective, low-cost intervention for treatment of chronic headaches among adolescents, according to a recent study. This retrospective chart review study evaluated a group education program for 155 adolescents, aged 12-17 years, enrolled in the US military medical system with at least 3 months of chronic headaches and who were referred to a headache evaluation clinic. The primary outcome of the study was self-reported number of days with a headache in the previous 30 days based on patient recall. Researchers found:
- Most participants in the program were female (114/155 [73.5%]) and suffered from migraine headaches (108/155 [69.8%]).
- Severe headache-related disability was reported by 40.6% of subjects (63/155).
- Subjects reported an average of 19 days with headache during the previous 30 days.
- Participation in the group education was associated with an 11.5-day decrease in the frequency of headaches during the previous 30 days at follow-up at least 6 months after the class, with largest decline seen in patients with the highest level of migraine-related disability at baseline.

Splenic artery embolization increases risk of complications
LAKE BUENA VISTA, FLA. – are at higher risk of infectious complications and readmissions in the long term, according to a study presented at the annual scientific assembly of the Eastern Association for the Surgery of Trauma.
As nonoperative treatments are becoming more common for managing blunt splenic injury (BSI), it is important to understand the risks associated with splenic artery embolization (SAE) and how this treatment may be impacting a larger trend of posttrauma readmissions, according to presenter Rishi Rattan, MD, an acute care surgeon at the University of Miami.
The retrospective study included 37,986 BSI patients admitted into the National Readmissions Database from 2010 to 2014, treated with either nonoperative management (NOM), SAE, or operative management (OM).
Readmission rates for infection after 30 days were significantly higher among SAE (15.4%) and OM (21.9%) patients, compared with NOM patients (6.7%), according to Dr. Rattan. Patients who underwent SAE also had a 17.2% rate of infection after 1 year; significantly higher than the 8.1% of patients who underwent NOM, although less than the 23.2% of those who underwent OM.
For readmission due to organ surgical site infection, patients with SAE had a higher frequency at 30-day (2.9%) and 1-year (3.9%) readmission, compared with both NOM (1.3%, 1.7%) and OM (2.0%, 2.2%).
This can be particularly problematic as these organ surgical site infections, deep in the abdominal cavity around the splenic bed, are usually more complicated to manage, compared with a superficial infection, explained Dr. Rattan. Physiologically, it makes sense that having dead tissue left in the splenic bed could lead to a rise in infection, although more data are necessary to confirm that hypothesis.
SAE was a significant predictive factor for complications after BSI, increasing the odds of 30-day and 1-year readmission by 76% and 99%, respectively, from organ surgical site infection, compared with NOM (P less than .01). Other predictive factors included hospital stays longer than 4 days, not being discharged to home, and a Charlson Comorbidity index score greater than 1.
With an incidence rate of readmission among embolization patients at 30 days and 1 year double that of NOM, Dr. Rattan and fellow investigators suggest surgeons should be conscious of the risks of SAE and OM, especially as infection is a major case of morbidity after trauma in splenectomy patients.
The investigators reported no relevant financial disclosures.

Nearly half of MS patients treated by primary docs miss out on meds
SAN DIEGO – than are those treated by neurologists, even though they have more symptoms.
Nearly 85% of those treated at MS centers by neurologists received the drugs, compared with just 51% of those treated at primary care offices, according to results of a study reported at ACTRIMS Forum 2018, held by the Americas Committee for Treatment and Research in Multiple Sclerosis.
Dr. Halpern spoke in an interview at the ACTRIMS Forum.
The researchers analyzed data from the Sonya Slifka Longitudinal Multiple Sclerosis Study and focused on MS patients who received care at MS centers (376 patients, all treated by neurologists), neurology practices (552 patients), and primary care practices (55 patients).
In the three groups, most of the patients were female (77%-82%). To a statistically significant degree, those who were treated at primary care practices, compared with those at MS centers, were more likely to be white (98% vs. 82%), to have less than a college education (69% vs. 42%), and to have Medicaid/veteran coverage or be uninsured (22% vs. 11%).
In terms of rates of patients receiving disease-modifying therapies, there was a small difference between MS centers (84%) and neurology practices (79%); P less than .05.
However, the gap between these patients and those treated by primary care doctors was wide: Only 51% in the latter group received disease-modifying therapies, even though they reported more symptoms in areas such as vision, walking, bowel, speech, and numbness, compared with those in the other groups (P less than .05).
There was no statistically significant difference among the groups in reported symptoms of tremor, headache, pain, fatigue, cognition, swallowing, depression, mood, and anxiety.
The study doesn’t explain why the MS patients treated by primary care physicians are missing out on care, and it is not known whether the absence of treatment makes their conditions worse.
However, “it’s been well documented that the disease-modifying therapies can reduce the disease progression and the likelihood of experiencing relapses,” Dr. Halpern said. “Individuals with MS who are not being appropriately treated are more likely to experience symptoms, relapses, and faster disability.”
He speculated that primary care doctors may be falling behind on the treatment front because they lack the training and expertise to properly prescribe the MS medications, which are “difficult and complex drugs.”
Whatever the case, he said, there’s a clear need for more collaboration between MS subspecialists and primary care doctors.
The study was funded by the National MS Society. Dr. Halpern reported no relevant disclosures.

There was no statistically significant difference among the groups in reported symptoms of tremor, headache, pain, fatigue, cognition, swallowing, depression, mood, and anxiety.
The study doesn’t explain why the MS patients treated by primary care physicians are missing out on care, and it is not known whether the absence of treatment makes their conditions worse.
However, “it’s been well documented that the disease-modifying therapies can reduce the disease progression and the likelihood of experiencing relapses,” Dr. Halpern said. “Individuals with MS who are not being appropriately treated are more likely to experience symptoms, relapses, and faster disability.”
He speculated that primary care doctors may be falling behind on the treatment front because they lack the training and expertise to properly prescribe the MS medications, which are “difficult and complex drugs.”
Whatever the case, he said, there’s a clear need for more collaboration between MS subspecialists and primary care doctors.
The study was funded by the National MS Society. Dr. Halpern reported no relevant disclosures.

OSA may provide cardioprotection
, according to researchers.
In a study of 127 patients presenting with acute coronary syndromes (ACS), median peak cardiac troponin-I (cTn-I) values were significantly higher in patients without obstructive sleep apnea, compared with OSA patients (10.7; interquartile range: 1.78-40.1, vs. 3.79; IQR: 0.37-24.3, respectively; P = .04 ). The findings were published Feb. 5 in CHEST.
The study comprised 89 OSA patients and 38 non-OSA patients who were admitted to a hospital for acute coronary syndromes. The OSA group had a median apnea-hypopnea index (AHI) of 32, while the non-OSA group had a median AHI of 4.8. There was no significant difference between the two groups in gender, age, or cardiovascular risk factors such as hypertension, diabetes mellitus, body mass index, dyslipidemia, and smoking.
The cohort was part of the Continuous Positive Airway Pressure (CPAP) in Patients With Acute Coronary Syndrome and Obstructive Sleep Apnea (ISAACC) study, a prior randomized, controlled trial that evaluated the effect of CPAP treatment on new cardiovascular events in patients with an episode of ACS and OSA, reported Alicia Sánchez-de-la-Torre, PhD, of the respiratory department at Hospital Universitari Arnau de Vilanova and Santa Maria in Catalonia, Spain, and her coauthors.
Respiratory polygraphy was performed in the first 24-72 hours after hospital admission, and patients with an AHI of at least 15 events per hour were considered to have OSA. Those with an AHI less than 15 events per hour were included in the non-OSA group.
Blood samples were collected from patients every 6 hours until two consecutive cTn-I measurements showed a decrease, with the highest measurement considered the peak cTn-I value.
Peak cTn-I value was significantly higher in non-OSA patients than in OSA patients. Median infarct size, measured by calculating the area under the cTn-I curve, was significantly different between the two groups (451 for non-OSA patients vs. 143 in OSA patients; P = .049), wrote Dr. Sánchez-de-la-Torre and her colleagues.
As cTn-I levels decreased, there was a trend toward increased OSA severity (P = .058). In the multivariable linear regression model used to assess OSA severity, patients with severe OSA had 61% lower cTn-I levels than non-OSA patients, the authors noted.
“These results suggest that patients with higher AHI are significantly more likely to have low cTn-I levels than patients without evidence of OSA, which could imply that patients with elevated AHI, particularly those with severe OSA, may experience less severe myocardial injury,” the authors said in the report. The findings “suggest that OSA has a protective effect in the context of MI,” they added.
Limitations of the study include exclusion of patients with severe ACS, exclusion of sleepy subjects, and assessment of myocardial injury using cTn-I as a biomarker, without further data to determine infarct size.
“The possible role of OSA in cardioprotection should be explored in future studies,” the authors concluded.

Although this study cannot definitively establish a clinically meaningful protective effect, it does provide important “preliminary evidence supporting the concept of OSA-induced cardioprotection” and challenges existing research, according to an editorial by Doron Aronson, MD, of the department of cardiology at Rambam Medical Center, Haifa, Israel, and coauthors (CHEST. 2018 Feb 153[2]:295-7. doi: 10.1016/j.chest.2017.07.036).
The results should be interpreted with caution, especially since accurate assessment of infarct size poses a challenge, they wrote.
“Myocardial infarct size is highly variable and is influenced by the duration of coronary occlusion, ST-segment elevation or non–ST elevation myocardial infarction, infarct location, residual antegrade infarct-related artery flow, collateral flow, the presence of non–culprit vessel coronary artery disease and myocardial metabolic demand,” they wrote. “Without accounting for these variables in a small study, results may be affected by variation in the characteristics of the patients.”
Though further study is needed, the findings may have “profound clinical implications regarding our therapeutic approach to patients with sleep apnea” if confirmed, the authors concluded.

Multisite, same-day cryolipolysis treatments don’t skew lipids, liver enzymes
Multiple, same-day cryolipolysis treatments don’t adversely affect serum lipids or liver enzymes, either acutely or after 12 weeks.
Among all the lipids measured, only triglycerides showed a significant increase, jumping from a mean 77 mg/dL to 83.4 mg/dL. The just over 6 mg/dL increase was “clinically trivial” and driven by a single patient in the 35-subject study, Kenneth B. Klein, MD, and his colleagues reported in Lasers in Surgery and Medicine.
Results of the small, prospective study are reassuring, if not surprising, the authors wrote. Even four flank treatments, as performed in this cohort, release only about 160 g of fat, at a rate of less than 2 g/day. “To put this figure in perspective, the typical American diet contains at least 75 g of fat per day. Moreover, it has been shown that consuming as much as 261 grams of fat per day causes no ill effects or laboratory abnormalities.”
The study included 35 men and women with a mean age of 45 years but a range of 20-67 years. The mean body mass index was 24.7 kg/m2, although the range was quite wide, at 18-29.7 kg/m2. All subjects underwent cryolipolysis of the lower abdomen and both flanks. Blood was drawn for analysis at baseline and at weeks 1, 4, and 14 after treatment. One patient didn’t complete the treatment because it was impossible to draw enough flank tissue into the applicator.
Patients experienced the expected procedural side effects of erythema, numbness, and edema, with a few reports of tingling and bruising. All of these resolved spontaneously. Immediately after the procedure, the mean pain score was 4 on a 1-10 scale; by week 12, there were no reports of pain.
Other than the triglyceride change in the single patient, there were no statistically or clinically significant changes from baseline to week 12 in total cholesterol (mean 186.5 mg/dL vs. 189.2 mg/dL), HDL cholesterol (71 mg/dL vs. 73.8 mg/dL), LDL cholesterol (100 mg/dL vs. 102.5 mg/dL), or very low-density cholesterol (15.7 mg/dL vs. 16.8 mg/dL). Although the mean triglyceride change was statistically significant, the final measurement was still well below the upper limit of reference (150 mg/dL).
The only liver enzyme change of note occurred in one patient, who had one sharp increase in aminotransferase. That was related to alcohol consumption the night before the week 12 blood draw.
The study was sponsored by Zeltiq Aesthetics, which manufactures the device used in the trial. Dr. Klein is a consultant to Zeltiq. All three coauthors were paid investigators; in addition, one of them, Eric P. Bachelor, MD, is on the Zeltiq speakers’ bureau.

VIDEO: With tinea capitis, don’t be fooled by a Wood’s lamp
KAUAI, HAWAII – When it comes to diagnosing tinea capitis, you really can’t rely on a Wood’s lamp, according to pediatric dermatologist Robert Silverman, MD.
The Wood’s lamp generally misses the most common cause of tinea capitis in urban and suburban environments today, Trichophyton tonsurans, said Dr. Silverman, a pediatric dermatologist and clinical associate professor in the department of pediatrics at Georgetown University, Washington.
The dermatoscope, which “will allow you to see what is called the black dots of tinea capitis very, very closely,” is far better, he said in an interview at the Hawaii Dermatology Seminar provided by the Global Academy for Medical Education/Skin Disease Education Foundation
He explained the limitations of the Wood’s lamp in this setting, and what to look for with a dermatoscope. He had other tips to share, too, from years of experience treating the condition, including how to differentiate tinea capitis on exam from its most common mimics, why it’s best to include a counter stain when using potassium hydroxide, and how to motivate parents to wash their child’s hair more frequently to reduce spores on the hair and scalp.
Dr. Silverman disclosed relationships with Pierre Fabre, Pfizer, and Regeneron.

Melanoma incidence increased in older non-Hispanic whites
reported Dawn M. Holman, MPH, of the division of cancer prevention and control at the Centers for Disease Control and Prevention, and her coauthors.
In non-Hispanic white females aged 15 years and older, 131,976 melanomas were diagnosed between January 2010 and December 2014. In non-Hispanic white males, 192,979 melanomas were diagnosed during this time period. More than 70% of melanomas were diagnosed in patients aged 55 years or older, the authors reported. In females, melanoma incidence rates ranged from 4.5/100,000 population in those aged 15-24 years to 60.9/100,000 population in those aged 85 years and older. For males, melanoma incidence ranged from 2.0/100,000 population in those aged 15-24 years to 198.3/100,000 population in men aged 85 years and older.
Investigators analyzed data from the CDC National Program of Cancer Registries and the National Cancer Institute’s Surveillance, Epidemiology, and End Results Program. Melanoma incidence rates and average annual counts by 10-year age groups were calculated from January 2010 to December 2014, as was average annual percent change (AAPC) by 10-year age groups from January 2005 to December 2014.
Overall, the increase in melanoma incidence was statistically significant for both males and females 15 years of age and older (AAPC, 1.4; P less than .05). However, melanoma incidence decreased significantly in younger patients aged 15-24 years, 25-34 years, and 35-44 years (AAPC, –5.1, –1.7, and –0.5 respectively; P less than .05), and increased significantly in those aged 55-64 years, 65-74 years, 75-84 years, and older than 85 years (AAPC, 1.3, 2.5, 3.6, and 4.6 respectively; P less than .05). The increase in melanoma incidence was statistically significant in men older than 54 years and in women older than 44 years, Ms. Holman and her associates reported in a research letter in JAMA Dermatology.
The findings suggest that recent decreases in indoor tanning and sunburn prevalence may account for the reduction in melanoma incidence over time, especially in adolescents and young adults, they said.
“Although primary skin cancer prevention efforts have often focused on children, adolescents, and young adults, the steady increase in melanoma incidence rates among older adults indicates a need for efforts that promote skin cancer preventive behaviors throughout adulthood. Such efforts could focus on groups at high risk, such as outdoor workers and intentional tanners,” Ms. Holman and her associates concluded.
The authors did not disclose any conflicts of interest. The study was partially supported by appointments to the CDC Research Participation Program through an interagency agreement with the U.S. Department of Energy.

Melanoma incidence rates and average annual counts by 10-year age groups were calculated from January 2010 to December 2014, as was average annual percent change (AAPC) by 10-year age groups from January 2005 to December 2014.
Overall, the increase in melanoma incidence was statistically significant for both males and females 15 years of age and older (AAPC, 1.4; P less than .05). However, melanoma incidence decreased significantly in younger patients aged 15-24 years, 25-34 years, and 35-44 years (AAPC, –5.1, –1.7, and –0.5 respectively; P less than .05), and increased significantly in those aged 55-64 years, 65-74 years, 75-84 years, and older than 85 years (AAPC, 1.3, 2.5, 3.6, and 4.6 respectively; P less than .05). The increase in melanoma incidence was statistically significant in men older than 54 years and in women older than 44 years, Ms. Holman and her associates reported in a research letter in JAMA Dermatology.
The findings suggest that recent decreases in indoor tanning and sunburn prevalence may account for the reduction in melanoma incidence over time, especially in adolescents and young adults, they said.
“Although primary skin cancer prevention efforts have often focused on children, adolescents, and young adults, the steady increase in melanoma incidence rates among older adults indicates a need for efforts that promote skin cancer preventive behaviors throughout adulthood. Such efforts could focus on groups at high risk, such as outdoor workers and intentional tanners,” Ms. Holman and her associates concluded.
The authors did not disclose any conflicts of interest. The study was partially supported by appointments to the CDC Research Participation Program through an interagency agreement with the U.S. Department of Energy.

In non-Hispanic white females aged 15 years and older, 131,976 melanomas were diagnosed between January 2010 and December 2014. In non-Hispanic white males, 192,979 melanomas were diagnosed during this time period. More than 70% of melanomas were diagnosed in patients aged 55 years or older, the authors reported. In females, melanoma incidence rates ranged from 4.5/100,000 population in those aged 15-24 years to 60.9/100,000 population in those aged 85 years and older.

EMS stroke field triage improves outcomes
LOS ANGELES – An emergency medical services protocol to identify large vessel occlusions and deliver patients to a comprehensive stroke center if it is within 30 minutes of travel time reduced the time to recanalization when compared against a separate protocol that optimized transfer of such patients from primary to comprehensive stroke centers.
The findings, which come from a sequential study conducted in an urban Rhode Island region, offer evidence to resolve the controversy over whether field triage in emergency medical services (EMS) units will improve outcomes, because field stroke severity scores won’t always be accurate, and longer travel to a comprehensive stroke center (CSC) could delay treatment to a patient who doesn’t need thrombectomy.
The region where the study was carried out has one CSC and eight primary stroke centers (PSCs). The large vessel occlusions transfer protocol instructed PSCs to contact the CSC when a patient scored 4 or 5 on the Los Angeles Motor Scale (LAMS), followed by CT and CT angiography. They then shared the resulting images with the CSC, which could make a decision whether to transfer the patient.
The field-based protocol relied on a LAMS score assessment by EMS personnel. Patients scoring 4 or 5 would then be delivered to the CSC if it was within 30 minutes from their current location. Patients scoring less than 4 would be brought to the nearest facility. In cases when the field LAMS score was 4 or greater and the nearest CSC was more than 30 miles away, EMS personnel were instructed to travel to the closest PSC, but immediately send word of an inbound patient that might need a transfer to a CSC. In those cases, the PSC’s goal was to get images to the CSC for review within 45 minutes. The protocol was executed out to 24 hours after the patient was last known well.
Even in patients who were closer to a PSC than a CSC, process outcomes were better with the field triage protocol. “Despite 8 additional minutes of transport time, IV TPA was given 17 minutes earlier, and recanalization occurred almost an hour earlier,” said Dr. McTaggart. “That would indicate that perhaps even a 30-minute window is too conservative of a protocol, because the number needed to treat for mechanical thrombectomy is 2 or 3, so you have this tremendously powerful treatment effect for these patients. If you can get it to them an hour earlier, it’s a no-brainer to me that they need to go to the right place the first time,” he said.
Instituting the changes was no picnic. Dr. McTaggart spent thousands of hours working with EMS personnel and emergency department physicians at PSCs. “It’s a lot of work, but the downstream gains are huge, not only from a disability standpoint for patients but for the economics of the health care system. We’re potentially saving patients from disability health care costs,” he said.
The study population included consecutive stroke patients in the region whose first contact was with EMS personnel during three time periods: before either change was made: (pre PSC-CSC transfer optimization, pre field triage, July 2015 to January 2016), after PSC optimization but only voluntary field triage (January 2016 to January 2017), and when both PSC optimization and field triage were mandatory (January 2017 to January 2018).
The patients had an anterior large vessel occlusion and mild to moderate early ischemic change. Outcomes included time from hospital arrival (PSC or CSC) to alteplase treatment, arterial puncture, and recanalization. Clinical measures included favorable outcomes (modified Rankin scale score 0-2) at 90 days, or discharge with a National Institutes of Health Stroke Scale score of 4 or less, in cases where 90-day follow-up did not occur.
A total of 38 patients were seen before any change, 100 after PSC optimization, and 94 after both PSC optimization and field triage were implemented. A Google Maps analysis showed that the median additional time required to travel to a CSC instead of a PSC was 8 minutes (interquartile range 4-12).
The time to first use of IV alteplase dropped from 54 minutes before any change to 49 minutes after PSC optimization, and 36 minutes after both PSC optimization and field triage. Similar drops were seen in time to arterial puncture (105 minutes, 101 minutes, 88 minutes) and time to recanalization (156 minutes, 132 minutes, 116 minutes). These differences did not reach statistical significance.
The clinical outcomes also became more favorable: 58% had a favorable outcome at 90 days with both protocols in place, compared with 51% with only PSC optimization and 31% before any changes (P = .049 for 31% to 58% comparison).
The researchers conducted a subanalysis of 150 patients for whom the PSC was closest. Of these, 94 went to a CSC and 56 went to a PSC. The elapsed time between EMS leaving the scene with the patient aboard and IV TPA treatment was an average of 51 minutes in patients taken to the CSC, compared with 68 minutes in patients taken to PSCs (P = .012). The time to arterial puncture was also shorter (98 minutes versus 155 minutes; P less than .001), as was time to recanalization (131 minutes versus 174 minutes; P less than .001).
CSC patients were more likely to have a favorable outcome (65% versus 42%; P = .01).
The study received no external funding. Dr. McTaggart reported having no financial disclosures.

VIDEO: Teriflunomide and dimethyl fumarate are comparable in relapsing-remitting MS
SAN DIEGO – New industry-funded research finds that
“The fundamental conclusion is that there’s little to separate them. If you look at efficacy, safety, and MRI scanning, there were no differences between the two medications that matter. ... Both drugs can be used with equal confidence,” said Stanley Cohan, MD, PhD, medical director of Providence MS Center in Portland, Ore.
Dr. Cohan spoke in a video interview at the meeting held by the Americas Committee for Treatment and Research in Multiple Sclerosis.
The researchers analyzed retrospective data collected in the phase 4 Teri-RADAR study, which tracked two groups of 50 patients each at MS centers in the United States as they took 14 mg of teriflunomide (Aubagio) daily or 240 mg of delayed-release dimethyl fumarate (Tecfidera) twice daily.
In both groups, participants had an average age of about 49 years, about three-quarters were women, and about 93% were white. Twenty-two percent of those in the teriflunomide group had relapses in the 18 months before the index date, compared with 10% of the dimethyl fumarate group.
The study – funded by Sanofi, maker of teriflunomide – followed up with patients at a mean of 15-16 months.
Mean annualized percentage of brain volume change (PBVC) was lower in teriflunomide-treated patients, compared with those treated with dimethyl fumarate (–0.2% vs. –0.5%; P = .02). Also, fewer teriflunomide-treated patients showed signs of annualized PBVC above a mean annualized brain volume loss rate threshold of 0.4% (25.9% vs. 58.6%; P = .01).
As for adverse effects, rashes affected none of the teriflunomide group but 28% of the dimethyl fumarate group. The teriflunomide group experienced skin reactions (12%) and diarrhea (16%), while these adverse events were not reported in the dimethyl fumarate group.
The study authors reported a variety of disclosures, and several are employees of Sanofi. Dr. Cohan reported a variety of disclosures, including multiple relationships with Sanofi.
