Long-term use of proton pump inhibitors was significantly associated with later diagnoses of dementia in adults aged 75 years and older in a prospective cohort study of more than 73,000 individuals. The findings were published online Feb. 15 in JAMA Neurology.

Overall, the risk of incident dementia was 44% higher among the 2,950 patients who received regular proton pump inhibitors, compared with 70,729 who didn’t receive PPIs (hazard ratio of 1.44), according to Willy Gomm, Ph.D., of the German Center for Neurodegenerative Diseases in Bonn, and his colleagues.

To assess the potential link between PPIs and dementia, the researchers reviewed data from a German insurance database during 2004-2011. The study population included 73,679 community-dwelling adults aged 75 years and older who were free of dementia at the start of the study (JAMA Neurol. 2016 Feb 15. doi: 10.1001/jamaneurol.2015.4791). The patients taking PPIs were slightly but significantly older than those not taking PPIs and had a higher proportion of women (P less than .001 for both). PPI users were also significantly more likely than nonusers to have a history of depression, stroke, coronary disease, and use of polypharmacy (P less than .001 for each).

The risk of incident dementia decreased with age, from 69% for patients aged 75-79 years to 49% among those 80-84-years and 32% among those aged 85 years and older.

In addition, the risk of dementia was not significantly different based on specific drug in a subgroup analysis of the three most often prescribed PPIs, omeprazole, pantoprazole, and esomeprazole, for which the hazard ratios were 1.51, 1.58, and 2.12, respectively.

“If PPIs have adverse effects, it is important to be aware of them,” Dr. Daniel E. Freedberg of Columbia University, New York, said in an interview. “When PPIs are indicated, the preponderance of data indicate that their benefits outweigh their potential risks,” he added. “Clinicians should reassure patients that this was a single study and that previous studies have reached different conclusions. Clinicians should focus on whether or not PPIs are indicated rather than on PPI side effects.”

Dr. Freedberg also noted several key limitations of the study.

“First, the authors were unable to adjust for crucial variables that might explain a noncausal link between PPIs and dementia. For example, lower socioeconomic status is an established predictor of dementia and may also be associated with PPI use. However, the authors could not capture socioeconomic status.

“Second, patients who use PPIs have more frequent and more intensive health care interactions than patients who do not use PPIs. These patients are thus also more likely to be diagnosed with dementia. This is another source for bias that the authors were not able to capture. Third, clinicians should be aware that this study was designed to compare extremes of PPI use,” Dr. Freedberg emphasized.

In addition, “In the primary analysis, patients were classified as exposed to PPIs only if they received at least one PPI prescription every 3 months for an 18-month period. Patients who used occasional PPIs were excluded from the study,” said Dr. Freedberg.

“The present study can only provide a statistical association between PPI use and risk of dementia,” the researchers noted. “The possible underlying causal biological mechanism has to be explored in future studies,” they wrote.

The researchers had no financial conflicts to disclose.

Hospital readmissions have declined in recent years for three conditions targeted under the Affordable Care Act, with smaller declines for other conditions, according to new research.

The study, published online Feb. 24 in the New England Journal of Medicine, found that 30-day readmission rates declined quickly after the passage of the ACA in 2010 and then slowed at the end of 2012. The researchers also analyzed trends in the use of observation units during the same period and concluded that the drop in readmissions was not being masked by a similar uptick in patients being seen under observation status (N Engl J Med. 2016 Feb 24. doi: 10.1056/NEJMsa1513024).

Under the ACA’s Hospital Readmissions Reduction Program, hospitals are financially penalized if they have higher-than-expected readmission rates for acute myocardial infarction, heart failure, and pneumonia.

The researchers, led by Rachael B. Zuckerman, M.P.H., of the Department of Health & Human Services, examined Medicare data from 3,387 hospitals from October 2007 through May 2015. Overall readmissions for acute myocardial infarction, heart failure, and pneumonia – the three conditions targeted in the readmissions reduction program – dropped from 21.5% to 17.8% during this time period. Readmissions for nontargeted conditions also dropped from 15.3% to 13.1%.

The researchers reported that readmissions for the targeted conditions were already declining before the ACA implementation (slope of monthly rate, –0.017), accelerating between April 2010 and October 2010 (–0.103), then leveling off through 2015 (–0.05). A similar pattern was seen with readmissions for conditions not targeted under the health law, though the declines were less pronounced.

Observation rates for the targeted conditions increased from 2.6% to 4.7% during the study period, while rates for nontargeted conditions rose from 2.5% to 4.2%. The researchers did not observe any significant associations increases in observation-unit stays – which were steady throughout the study period – and the implementation of the ACA.

“It seems likely that the upward trend in observation-service use may be attributable to factors that are largely unrelated to the Hospital Readmissions Reduction Program, such as confusion over whether an inpatient stay would be deemed inappropriate by Medicare recovery audit contractors,” the researchers wrote.

Though the observational design of the study could not confirm a causal link between the ACA penalties and the drop in readmissions, the findings suggest that the declines are not solely a response to the ACA.

The health law likely “catalyzed behavioral change by many hospitals” that was already underway, possibly because of broader concern about readmissions and to earlier Medicare initiatives designed to reduce them. Also, the investigators noted, hospitals may have been helped by other government efforts on the readmission front, including the dissemination of best practices by the Centers for Medicare & Medicaid Services.

The study was funded by HHS and the researchers were agency employees. They reported having no other financial disclosures.

Out-of-state residents appear to be driving the recent increases in marijuana-related emergency department visits in Colorado, Dr. Howard S. Kim and his associates reported online Feb. 24 in the New England Journal of Medicine.

Using statewide data from the Colorado Hospital Association, they found that ED visits related to cannabis by out-of-state residents rose from 78 per 10,000 ED visits in 2012 to 163 per 10,000 in 2014, an increase of 109%. For Colorado residents, cannabis-related ED admissions over that same time period went up 44% – from 70 per 10,000 to 101, said Dr. Kim of Northwestern University, Chicago, and his associates (N Engl J Med. 2016 Feb 24;374[8]:797-8. doi:10.1056/NEJMc1515009).

The investigators also looked at a single urban academic hospital in Aurora, Colo., and found that cannabis-related ED visits there for out-of-state residents went from 85 per 10,000 visits in 2013 to 168 per 10,000 in 2014, compared with respective rates of 106 and 112 for Colorado residents.

“The flattening of the rates of ED visits possibly related to cannabis use among Colorado residents in an urban hospital may represent a learning curve during the period when marijuana was potentially available to Colorado residents for medical use (medical marijuana period) but was largely inaccessible to out-of-state residents,” they suggested.

WASHINGTON – Robotic angioplasty may deliver the same advantages when percutaneous coronary intervention is indicated for acute myocardial infarction as currently claimed for an elective PCI, according to results from a proof-of-principle study.

The first robotic PCI system, CorPath 200, was approved by the U.S. Food and Drug Administration in 2012, but the registration trial, called PRECISE (Percutaneous Robotically Enhanced Coronary Intervention), excluded patients with coronary thrombosis, according to a team of investigators at the Frederik Meijer Cardiovascular Institute, Grand Rapids, Mich. The current study focused exclusively on this population.

In “an initial experience” with robotic PCI in 17 acute MI patients led by Dr. Ryan D. Madder, an interventional cardiologist, “technical success” was achieved in 100% of patients with no repeat revascularizations in follow-up so far.

“These preliminary observations support the performance of larger studies to determine the role of robotic PCI in the treatment of acute MI,” said Andrew O’Brien, a medical student at Michigan State University, Ann Arbor, who presented the data at the meeting, sponsored by the Cardiovascular Research Institute at Washington Hospital Center.

The major proven advantage of robotic PCI is that it reduces radiation exposure to the operator, Mr. O’Brien said. While the procedure was performed in this study behind a lead-lined cockpit, it was noted that the operator works solely on the basis of imaging and could be anywhere, including at another facility. In addition, robotic PCI has at least a theoretical advantage of greater precision relative to conventional PCI.

In this study, technical success was defined as less than 30% residual stenosis after PCI in the absence of a PCI-associated death or the need for a repeat revascularization prior to hospital discharge. The median age of the 17 acute MI patients was 59 years with a range of about 10 years younger or older. Most (71%) were male. Radial arterial access was used in all cases.

Only 23% of the patients met criteria for relatively simple lesions (class A or B1). Just over half (53%) had class B2 lesions, which require at least two complicating characteristics, such as moderate tortuosity, irregular contour, or moderate to heavy calcification, and the remainder had class C lesions. In 10 cases (59%), an angiographic filling defect consistent with thrombus was present at the culprit lesion site.

In addition to achieving the goal reduction in residual stenosis without major adverse cardiovascular events in all patients, the investigators reported that procedural time, which averaged 69 minutes from the time of sheath insertion to removal of the guide catheter, was “acceptable.” The longest procedural time was under 100 minutes.

“We used the same criteria for evaluating outcomes as employed in the original PRECISE study,” Mr. O’Brien said. He explained that acute MI patients were excluded in the published PRECISE trial data because there was no protocol at that time for converting to a conventional procedure on an urgent basis in the case of unexpected problems. With more experience, there was greater confidence that urgent complications could be addressed.

In the multicenter PRECISE trial, which led to approval of the robotic system, 164 candidates for elective PCI were enrolled (J Am Coll Cardiol. 2013;61[15]:1596-1600). Technical success was 98.8%. Although there was no control arm, radiation exposure was reported to be 95% lower for operators participating in that study than levels found at the traditional table position.

Data from the current study provide preliminary evidence that robotic PCI is feasible for management of acute MI. While confirmatory studies are needed for this indication, the Michigan investigators also advocated more studies to evaluate whether robotic PCI improves outcome. They cited the potential for more precise placement of stents to reduce the risk of complications.

“Robotic PCI is still not very widely performed,” said coinvestigator Andrew LaCombe, who suggested that its potential advantages deserve broader evaluation.

Dr. Madder disclosed a financial relationship with InfraRedx.

“We used the same criteria for evaluating outcomes as employed in the original PRECISE study,” Mr. O’Brien said. He explained that acute MI patients were excluded in the published PRECISE trial data because there was no protocol at that time for converting to a conventional procedure on an urgent basis in the case of unexpected problems. With more experience, there was greater confidence that urgent complications could be addressed.

In the multicenter PRECISE trial, which led to approval of the robotic system, 164 candidates for elective PCI were enrolled (J Am Coll Cardiol. 2013;61[15]:1596-1600). Technical success was 98.8%. Although there was no control arm, radiation exposure was reported to be 95% lower for operators participating in that study than levels found at the traditional table position.

Data from the current study provide preliminary evidence that robotic PCI is feasible for management of acute MI. While confirmatory studies are needed for this indication, the Michigan investigators also advocated more studies to evaluate whether robotic PCI improves outcome. They cited the potential for more precise placement of stents to reduce the risk of complications.

“Robotic PCI is still not very widely performed,” said coinvestigator Andrew LaCombe, who suggested that its potential advantages deserve broader evaluation.

NEW ORLEANS – Three potentially useful blood-based biomarkers of relapse and of the response to glatiramer acetate treatment have been identified in patients with relapsing-remitting multiple sclerosis (RRMS).

The study was small, so much more needs to be done to move the findings to the bedside. Nonetheless, the hope is that the findings will someday help guide treatment decisions and outcomes in MS patients, Adam Kruszewski, a medical student at the University of Maryland, Baltimore, commented in a poster presentation at the meeting held by the Americas Committee for Treatment and Research in Multiple Sclerosis.

The study had its roots in the researcher’s prior findings that the Response Gene to Complement (RGC)–32 is expressed by CD3+ and CD4+ T cells in peripheral blood mononuclear cells (PBMCs) and in brain tissue from RRMS patients. As well, RGC-32 regulates the expressions of Fas ligand (FasL) and interleukin-21 (IL-21), and the activities of CDC2 and Akt.

In the current study, the investigator explored the potential value of RGC-32, FasL, IL-21, CDC2, and Akt as longitudinal biomarkers of relapse and as a way of gauging the response to the treatment of RRMS patients with glatiramer acetate – one of the most common immunomodulatory approaches used in RRMS therapy.

A cohort of 15 glatiramer acetate–treated RRMS patients was enrolled over a 2-year period. The battery of inclusion criteria included an age of 18-65 years; meeting the McDonald criteria for definite MS; a disease course featuring relapses and remissions; newly diagnosed MS or MS not treated with currently used immunomodulatory drugs for 3 months prior to study entry; no exacerbations in the 4 weeks before the study; no steroid therapy for 4 weeks prior to study enrollment; no treatment with natalizumab (Tysabri), fingolimod (Gilenya), dimethyl fumarate (Tecfidera), mitoxantrone, cyclophosphamide, or investigational drugs during the prior year; and an Extended Disability Status Score (EDSS) of 0-5.5. Exclusion criteria were a history of autoimmune disorders, vascular disease, or active acute or chronic infections; use of antibiotics in the last 30 days; a history of intracranial or intraspinal tumor or metabolic myelopathy; or a history of alcohol or drug abuse.

The 15 patients were clinically monitored and PBMCs were collected at 0, 3, 6, and 12 months. mRNA expression of the five candidate biomarkers in the PBMCs was determined using real-time quantitative polymerase chain reaction testing. Nonresponders to glatiramer acetate treatment were defined as patients who exhibited two or more relapse events following the initiation of the treatment.

Acute relapse was associated with decreased expression of RGC-32 and FasL (both P less than .0001) and increased expression of IL-21 (P = .04). No relapse-associated changes in CDC2 or AKT were evident. Compared with those who did not respond to glatiramer acetate, responders displayed an increased expression of RGC-32 and FasL (both P less than .0001), and a decreased expression of IL-21 (P = .02).

Receiver operating characteristic analysis was done to find the cutoff values that best distinguished treatment responders from nonresponders for each candidate biomarker. The probability of accurately detecting relapse was 90% for RGC-32, 88% for FasL, and 75% for IL-21. The probability of accurately detecting response to glatiramer acetate was 85%, 90%, and 85% in the same respective order.

“Right now, there is no test that can help identify a responder or nonresponder in MS therapy. Often, treatment is started and then a trial and error process with time determines the treatment course,” said Mr. Kruszewski during an interview at the poster.

The aim is to expand these results with RCG-32, FasL, and IL-21 to a randomized, controlled trial with the goal of tailoring treatment at the early stage of MS.

NEW ORLEANS – Research from Australia shows that disability in multiple sclerosis (MS) is independent of past damage, even in people whose disease is moderately advanced, with further disease progression varying widely in severity.

The findings should prompt a rethink of the policy of ceasing treatment when MS-related disability becomes more advanced.

Brian Hoyle/Frontline Medical News

“Our main findings were that moderately advanced multiple sclerosis is indeed independent of previous disease, but still extremely variable. Higher relapse rates later in disease increased the risk of disability worsening. More promisingly, more time spent on therapy later in disease lowered the risk of disability progression to EDSS [Expanded Disability Status Scale] 6 or 6.5,” Nathaniel Lizak said in an interview at the meeting held by the Americas Committee for Treatment and Research in Multiple Sclerosis.

The study sought to identify factors that modified progression in early and moderately advanced MS. Three prior cohort studies had not shed light on the variability in disease trajectory during moderately advanced MS.

“We wanted to examine how much variability there was later in disease, what determined this variability, and to confirm whether later disease was really independent of previous disease, as was suggested in previous studies,” said Mr. Lizak of Monash University, Clayton, Australia, and the University of Melbourne. The influences of relapse rate and proportion of time treated prior to and during each disability time period, age, and disease duration at baseline on the progression to moderate MS disability (EDSS 6 or 6.5) were assessed. The hypothesis was that, even at a later stage of MS, disease progression varies from patient to patient, and that some patients can benefit from immunomodulatory therapy.

The time between EDSS steps 3-6 (n = 1,560, 71% female, 40.9±9.9 years old at baseline), 4-6 (n = 1,504, 69% female, 43.0±9.6 years old at baseline), and 6-6.5 (n = 1,231, 67% female, 46.5±10.2 years old at baseline) were analyzed for the 32,336 patients included in the MSBase large, international, observational MS cohort study who met the inclusion criteria. Median disease duration at baseline was 9.4, 11.1, and 14.0 years in the same respective order.

Pre- and postbaseline disability trajectories showed large coefficients of variance and did not correlate. The probability of reaching the outcome EDSS was independent of prebaseline variables, but was increased if relapse during any particular EDSS was more frequent (hazard ratios, 1.58-3.07; P less than .001). At each measured stage of MS, higher-efficacy therapies were beneficial and lowered the risk of progression (HR, 0.27-0.68; P less than .02).

Some countries, such as New Zealand, by policy don’t allow patients to receive treatments if they display moderate or significant disability. In other places this can be common practice because of concerns with treatment-related side effects or affordability. The main driver of this practice is that the clinical trials of most MS therapies that have validated these medications specifically recruited patients with low disability scores. So, according to Mr. Lizak, the evidence exists only for therapies at lower disability scores.

“These results are important as they show that there is still hope. Reaching disability landmarks of EDSS 3, 4, and 6 does not guarantee continuous worsening of disability. Doctors still have the ability to reduce their patients’ risk of attaining further disability, even at later stages of disease,” said Mr. Lizak.

The hope is that the data will change clinical practice to encourage more therapy even when substantial disability has accumulated.

“Translating results into everyday practice is difficult, and doctors must always weigh the risks and benefits. We hope that our work will influence the clinical decision to, where in doubt, favor high-efficacy treatments at later disease stages. That’s not to say that patients should be blindly treated, as side effects always merit consideration. But we hope our work will inform neurologists that there is evidence supporting treating patients with more advanced disability. Where, by practice or policy, treatments are not provided to patients who have accumulated significant disability, we hope to change such clinical practice,” said Mr. Lizak.

The study did not require funding. Mr. Lizak had no disclosures.

Loss of distensibility of the pulmonary vasculature may be a marker that allows earlier detection of impending pulmonary hypertension, based on hemodynamic data from the medical records of 90 patients across the spectrum of pulmonary vascular disease.

Normal pulmonary circulation is distensible, allowing distension and recruitment of the pulmonary vasculature during exertion that in turn reduces pulmonary vascular resistance. Loss of this distensibility increases resistance and thus pulmonary arterial pressure, and is a characteristic of mild pulmonary vascular disease. Such disease is a precursor of full-blown pulmonary hypertension (PH), which “is a relatively late hemodynamic event in the evolution of pulmonary vascular disease,” said Dr. Edmund M. T. Lau of Université Paris-Sud, and his associates.

The percentage change in vascular diameter per mm Hg increase in distending pressure has been proposed for estimating the distensibility of resistive pulmonary vessels. This “distensibility value” has been assessed in animal studies and in healthy human subjects, but has not yet been assessed as a possible marker of mild pulmonary vascular disease or PH.

The researchers assessed this distensibility value in 31 patients with PH, 33 with mild pulmonary vascular disease but no PH as yet, and 26 control subjects with no pulmonary vascular disease. The data were obtained from the medical records of these patients, who had undergone right-sided heart catheterization, both at rest and during exercise, over a 6-year period.

The percentage change in vascular diameter per mm Hg increase in distending pressure was “strikingly reduced” (0.45%/mm Hg) in the mild pulmonary vascular disease group compared with the control group (1.4%/mm Hg). As expected, the group with PH had the lowest distensibility value, at 0.25%/mm Hg.

Using a cutoff value of 0.76%/mm Hg allowed the researchers to distinguish control subjects from patients with mild disease with a sensitivity of 88% and a specificity of 100%. “To our knowledge, this is the first study to validate the fit of [this] model in subjects with pulmonary vascular disease and to demonstrate that [percentage change in vascular diameter per mm Hg increase in distending pressure] is dramatically reduced in patients who have mild pulmonary vascular disease without manifest PH.

“Taken together, our findings suggest that vascular distensibility is markedly attenuated prior to the development of PH and that [this value] may serve as a useful vascular index in the setting of early disease detection,” Dr. Lau and his associates said (CHEST 2016;149:353-61).

The distensibility value calculated for this study’s control group (1.4%/mm Hg) was slightly lower than that reported in the literature for normal, healthy subjects and in vitro animal vessels (2%/mm Hg). That is likely because the control participants were older than the subjects in previous studies, and vascular distensibility is known to decrease with increasing age, the researchers said.

They added that it might be useful to calculate the distensibility value when patients suspected of having pulmonary vascular disease undergo invasive pulmonary hemodynamic evaluations. “It would be of particular interest to assess [it] in populations at a high risk of developing PH, such as carriers of the BMPR2 mutation and patients with systemic sclerosis.”

Obviously, estimating the distensibility value using noninvasive evaluation would be preferable, the researchers noted. Preliminary studies of healthy control subjects and carriers of the BMPR2 mutation undergoing stress ECG testing have shown that calculating the distensibility value is feasible using Doppler echocardiography data, they added.

This study was supported by Fonds de Dotation Recherche en Santé Respiratoire, Fondation du Souffle, and the INSERM–University of Sydney Exchange Grant. Dr. Lau reported having no relevant financial disclosures; his associates reported ties to Actelion, Aires, Bayer, Bristol-Myers Squibb, GlaxoSmithKline, Novartis, Pfizer, and United Therapeutics Corporation.

The percentage change in vascular diameter per mm Hg increase in distending pressure was “strikingly reduced” (0.45%/mm Hg) in the mild pulmonary vascular disease group compared with the control group (1.4%/mm Hg). As expected, the group with PH had the lowest distensibility value, at 0.25%/mm Hg.

Using a cutoff value of 0.76%/mm Hg allowed the researchers to distinguish control subjects from patients with mild disease with a sensitivity of 88% and a specificity of 100%. “To our knowledge, this is the first study to validate the fit of [this] model in subjects with pulmonary vascular disease and to demonstrate that [percentage change in vascular diameter per mm Hg increase in distending pressure] is dramatically reduced in patients who have mild pulmonary vascular disease without manifest PH.

“Taken together, our findings suggest that vascular distensibility is markedly attenuated prior to the development of PH and that [this value] may serve as a useful vascular index in the setting of early disease detection,” Dr. Lau and his associates said (CHEST 2016;149:353-61).

The distensibility value calculated for this study’s control group (1.4%/mm Hg) was slightly lower than that reported in the literature for normal, healthy subjects and in vitro animal vessels (2%/mm Hg). That is likely because the control participants were older than the subjects in previous studies, and vascular distensibility is known to decrease with increasing age, the researchers said.

They added that it might be useful to calculate the distensibility value when patients suspected of having pulmonary vascular disease undergo invasive pulmonary hemodynamic evaluations. “It would be of particular interest to assess [it] in populations at a high risk of developing PH, such as carriers of the BMPR2 mutation and patients with systemic sclerosis.”

Obviously, estimating the distensibility value using noninvasive evaluation would be preferable, the researchers noted. Preliminary studies of healthy control subjects and carriers of the BMPR2 mutation undergoing stress ECG testing have shown that calculating the distensibility value is feasible using Doppler echocardiography data, they added.

This study was supported by Fonds de Dotation Recherche en Santé Respiratoire, Fondation du Souffle, and the INSERM–University of Sydney Exchange Grant. Dr. Lau reported having no relevant financial disclosures; his associates reported ties to Actelion, Aires, Bayer, Bristol-Myers Squibb, GlaxoSmithKline, Novartis, Pfizer, and United Therapeutics Corporation.

Several older physicians have emphasized to me the importance of choosing an excellent disability insurance policy during residency. However, choosing the right policy can be a difficult task. The policy definitions are complicated, and there is a lot of fine print. To understand this confusing topic, start with answers to these 3 questions: What is my most valuable asset? When is the best point in my career to purchase disability insurance? What would I do if I were no longer able to perform the material and substantial duties of my occupation as a dermatologist?

A Resident’s Assets

In the world of disability insurance, your most valuable assets are your education and your ability to earn an income in the future.^1,2 A resident’s ability to earn an income in the future reflects a massive investment of time, cost of education, and postponed accruement of wealth due to time spent in training. Any negative impact on your health (eg, back injury, vision loss, hand injury) can jeopardize these assets. Purchasing disability insurance while still in dermatology residency will protect this investment; it also will ensure that you obtain a policy while you are still healthy.^1,2

Choosing a Policy

Disability insurance comes in 2 main forms: individual or group. Individual insurance may be slightly more expensive but may offer better coverage than group insurance. Group insurance often is offered through a large medical association such as the American Academy of Dermatology. Group insurance may be less expensive but often has more limits to coverage. A definite must-have in a disability insurance policy is one that has guaranteed renewal and is noncancellable.^1-3

Interestingly, women are considered a higher risk for disability, and many insurance policies will charge a higher monthly rate for women than men because women are slightly more likely than men to develop a disability, and women are more likely to develop a disability that prevents them from being able to work.⁴ Some insurance companies do offer a unisex policy, which does not discriminate.

When choosing a policy, you want to carefully read the vendor’s definition of disability. The best definition of the term disability is going to be one that includes phrases such as “unable to perform the material and substantial duties of your [own] occupation . . . even if you are gainfully employed in another occupation.”^1-3,5,6 This definition of disability is the least restrictive and would allow you to receive full benefits even if you are able to work in another capacity or occupation.^1-3,5,6 The benefit period of the policy also is something to choose carefully. It is recommended to choose a benefit period that extends to at least 65 years of age.^1-3,5 It is important to remember that the devil is in the details; for example, some disability insurance policies with more restrictive definitions will not pay you benefits if you are working in another capacity (eg, a physician who develops an injury that prohibits working with patients and then chooses to work in another capacity).

Some policies will only pay benefits if you become totally disabled. Shy away from these more restrictive policies; instead, look for a policy that has a liberal definition of what constitutes disability and allows you the option to add in a future purchase option rider. It is important that your policy includes a future purchase option rider, which means that as your income increases you have the option to purchase an increase in your disability coverage.^1-3,5 Look for a policy that allows you to be insured without penalizing you for preexisting conditions; during residency is one of the few times some policy vendors will do it, as they assume residents are generally young and healthy.^1-3,5,7

Final Thoughts

When you choose your policy, read the details carefully. Finally, remember that other physicians in the community are available as resources; they can be a wealth of information on different policies. There are many websites available to read more on this topic. Often, your training institution will offer a disability policy for the duration of your residency. Many residents choose to purchase their postresidency policies while in their third or fourth year of training. Take the time to choose a good policy now; you will be glad you did.

SAN ANTONIO – Prehospital blood transfusions during air medical transport did not improve 24-hour or in-hospital mortality at Vanderbilt University Medical Center, Nashville.

Investigators there reviewed 5,581 patients transported by helicopter to Vanderbilt from the scene of injury from the period of 2007-2013; they excluded patients who died on the helipad or in the ED. Average flight time was 48 minutes; 231 patients (4%) received prehospital blood transfusions (PBT) of up to two units of O negative packed red blood cells, which is all that the helicopters carried. The decision to transfuse was up to helicopter personnel who were advised to transfuse hemodynamically unstable patients and those who had lost more than a half liter of blood.

Vanderbilt reviewed its data because although PBT has become widespread in air medical transport, results from military and civilian studies are mixed. “A lot of evidence indicates that early, aggressive resuscitation with blood products improves survival once patients arrive at the hospital. It makes sense that starting the process early would improve outcomes, but relatively little is known about the prehospital environment,” said investigator and general surgery resident Dr. Benjamin Miller.

PBT didn’t seem to help at Vanderbilt. On multivariable regression, in-flight transfusion did not improve 24-hour mortality (OR 1.22; 95% CI 0.61-2.44) or overall in-hospital mortality (OR 1.20; 95% CI 0.55-1.79). It was the same story when 195 transfused patients were matched to 195 who were not transfused, based on mechanism of injury, scene vital signs, injury severity, travel duration, and other measures. Even with matching, PBT did not improve 24-hour mortality (OR 1.04; 95% CI 0.54-1.98) or overall mortality (OR 1.05; 95% CI 0.56-1.96).

There was a trend for improved 24-hour survival with transfusion when injury severity scores were below 20, but it wasn’t statistically significant, perhaps because few of the less injured patients died.

“Our results show no effect of PBT on 24-hour and overall in-hospital mortality. It’s puzzling to us because it’s counterintuitive to the damage control resuscitation strategy,” Dr. Miller said at the annual scientific assembly of the Eastern Association for the Surgery of Trauma.

The findings aren’t robust enough for Vanderbilt to cancel PBT, but they do suggest possible areas for improvement.

Maybe “one or two units of blood are not enough for patients who are severely injured and rapidly exsanguinating, or [maybe] fresh frozen plasma or platelets are needed. Maybe the trigger for transfusion is too low, or too high. It’s time from a prospective study,” Dr. Miller said.

Vanderbilt doesn’t use tranexamic acid to control trauma bleeding. The study didn’t capture volume of crystalloid infused, serum markers of shock, or coagulation study results.

Subjects were in their late 30s, on average, and 70% were men. Transfusions were more likely in younger patients and those with penetrating injuries, poorer at-scene vital signs and Glasgow coma scores, more severe injuries, and lower hematocrits. With the exception of younger age, those factors were also associated with death.

The investigators had no disclosures.

Since early summer, a 51-year-old woman has had an itchy rash on her trunk. It manifested after she intentionally lost more than 200 lb, which resulted in deeper and more pronounced skinfolds. The same skinfolds are repeatedly involved in flares of the rash, which is worse on particularly hot days. She was diagnosed with “yeast infection” but the problem failed to respond to oral fluconazole and topical nystatin.

The patient has multiple health problems, including diabetes, chronic anxiety, and hypertension.

EXAMINATION
There is a deep, linear, concave fold in the skin of the right flank, the long axis of which is transversely oriented. Within this fold, a fiery red rash is seen; its margins exactly match the outline of skin-on-skin contact. The surface of the affected skin is macerated and wet looking. There is neither tenderness nor increased warmth on palpation.

What is the diagnosis?

DISCUSSION
This phenomenon is called intertrigo, and it’s a subject of much confusion. This is especially true in primary care, where almost any intertriginous rash is labeled “yeast infection” and treated with anti-yeast medications that fail as monotherapy. In fact, true yeast infections in or on the skin are quite unusual.

Here is what happens when skin is held on skin: Moisture can accumulate, temperature rises, and skin becomes macerated and starts to break down. Organisms already present on the skin begin to multiply and can contribute to the inflammatory burden. Any pre-existing skin disease (eg, seborrhea, eczema or psoriasis) can flare under these conditions, further breaking down the epidermal barrier. With the right mix of these and other factors (severe obesity, diabetes, immunosuppression, hot weather), yeast can play a bigger role in the problem—but it is usually a minor factor.

Intertrigo is common under the breasts, in the axillae, and in abdominal panniculi. It can also be seen, as in this case, in large folds on the trunk, or even on the legs. Most cases of diaper rash involve at least a component of intertrigo.

The factors that predispose to intertrigo tend to be chronic, making the problem chronic as well. The patient and family (if appropriate) need to understand this, as well as the seasonal effects (the condition will be worse in warm months but improve in winter).

Treatment should be directed at reducing moisture in the area. This can be achieved by opening it up to air as much as possible, using aluminum acetate solution soaks to dry out the skin, placing strips of cotton or linen cloth to separate skinfolds, or applying antiperspirants or talcum-based powder.

For acute treatment, class 4 or 5 steroid creams can be used for short periods. An OTC topical anti-yeast cream, such as clotrimazole or miconazole, can be added.

The onset of such a rash, without obvious predisposing factors, should prompt consideration of other items in the differential. These include cutaneous T-cell lymphoma, Paget’s disease, or zinc deficiency–related conditions. More common lookalikes include contact or irritant dermatitis.

TAKE-HOME LEARNING POINTS
• As its name suggests, intertrigo is a condition affecting the intertriginous areas (eg, skin folds); common locations are under breasts or in the axillae, groin, or panniculi.

• Though yeast organisms can play a role in the development of intertrigo, treatment with anti-yeast products as monotherapy rarely work.

• Instead, management of intertrigo must be directed at the causative factors: heat, sweat, and friction.

• Intertrigo is difficult to treat, in large part because the major causative factors (weight, heat, sweat) are hard to change.
