                     score="0.013"
                     href="http://www.medpagetoday.com/MeetingCoverage/AAN/tb/18406?impressionId=1265817384416"
                     
      &lt;p&gt;TORONTO  --  Women whose mothers consumed high levels of vitamin D during pregnancy have a lower risk of developing multiple sclerosis, a large, observational study confirmed.&lt;/p&gt;
&lt;p&gt;Mothers who reported the highest intake during pregnancy were 45% less likely to have a daughter who subsequently developed the disease than those who consumed the least vitamin D (RR 0.55, 95% CI 0.35 to 0.88), according to Fariba Mirzaei, MD, MPH, a doctoral student at the Harvard School of Public Health.&lt;/p&gt;
&lt;p&gt;Mirzaei is scheduled to report the findings at the American Academy of Neurology (AAN) meeting in April.&lt;/p&gt;
&lt;p&gt;Lily Jung, MD, a neurologist at Swedish Medical Center in Seattle, said in an interview that the study &quot;adds more fuel to the fire that low vitamin D is important in the genesis of MS,&quot; which has been demonstrated in previous studies. (See &lt;a href=&quot;http://www.medpagetoday.com/Neurology/MultipleSclerosis/4738&quot; mce_href=&quot;http://www.medpagetoday.com/Neurology/MultipleSclerosis/4738&quot; target=&quot;_blank&quot;&gt;High Blood Levels of Vitamin D May Lower MS Risk&lt;/a&gt;)&lt;/p&gt;
&lt;p&gt;She said it&apos;s unclear why vitamin D is associated with risk of multiple sclerosis.&lt;/p&gt;
&lt;p&gt;&quot;There&apos;s an idea that perhaps there might be receptors that are turned on by vitamin D levels that give some form of protection, but that is very preliminary information and we&apos;re still learning a lot about that,&quot; said Jung, who is also a spokeswoman for the AAN.&lt;/p&gt;
&lt;p&gt;Although the link between vitamin D and risk of multiple sclerosis has been demonstrated before, gestational exposure to the vitamin has not been studied.&lt;/p&gt;
&lt;p&gt;To fill that gap, Mirzaei analyzed data from the Nurses&apos; Mothers&apos; Study, which includes a subcohort of the two Nurses&apos; Health Studies that was restricted to nurses whose biological mothers completed a questionnaire in 2001 about their diet during pregnancy.&lt;/p&gt;
&lt;p&gt;The current analysis included 35,794 nurse-mother pairs.&lt;/p&gt;
&lt;p&gt;During the 16-year study period, 199 of the nurses were diagnosed with multiple sclerosis.&lt;/p&gt;
&lt;p&gt;In addition to a lower risk of disease among those whose mothers consumed the largest amounts of vitamin D, those whose mothers had the highest predicted serum 25-hydroxyvitamin D levels also had a reduced risk of having a daughter with the disease (RR 0.58, 95% CI 0.37 to 0.90).&lt;/p&gt;
&lt;p&gt;In an analysis of milk drinking alone, mothers who drank at least four glasses a day had a nonsignificant reduced risk of having a daughter who would develop multiple sclerosis compared with those who drank less than three glasses a month (RR 0.44, 95% CI 0.16 to 1.23).&lt;/p&gt;
&lt;p&gt;However, there was a significant trend for lower risk of multiple sclerosis with increasing milk consumption (&lt;em&gt;P&lt;/em&gt;=0.001).&lt;/p&gt;
&lt;p&gt;Jung noted that the study was limited by the use of questionnaires decades after a pregnancy to determine dietary intake of vitamin D.&lt;/p&gt;
&lt;p&gt;Nevertheless, she said, &quot;this is very consistent with what we&apos;re seeing elsewhere in terms of vitamin D in moms and the risk of MS in kids.&quot;&lt;/p&gt;

                     score="0.01"

      Herbal medicines are not always the harmless nostrums that many patients and even some physicians think, but may actually contribute to cardiovascular morbidity and mortality, researchers warned in a review covering 44 years of research into the subject.&lt;br&gt;
&lt;br&gt;Many such products, including aloe vera, ginkgo biloba, ginseng, and green tea, can interact with conventional cardiovascular drugs and lead to serious adverse reactions, according to Arshad Jahangir, MD, of the Mayo Clinic in Scottsdale, Ariz., and two other Mayo physicians.&lt;br&gt;
&lt;br&gt;&quot;There is a clear need for better public and physician understanding of herbal products through health education, early detection and management of herbal toxicities, scientific scrutiny of their use, and research on their safety and effectiveness,&quot; they wrote in the Feb. 9 &lt;em&gt;Journal of the American College of Cardiology&lt;/em&gt;.&lt;/p&gt;
&lt;p&gt;Jahangir and colleagues also called for increased regulation of such products, at least requiring manufacturers of herbal medicines to register with the FDA and provide evidence of good manufacturing practices.&lt;/p&gt;
&lt;p&gt;&quot;Some of these adverse drug reactions are preventable,&quot; Jahangir told &lt;em&gt;MedPage Today&lt;/em&gt; in a telephone interview. &quot;Simple things like taking a good history or giving that history and discussing these issues, probably we can avoid [such reactions].&quot;&lt;/p&gt;
&lt;p&gt;Other physicians contacted by &lt;em&gt;MedPage Today&lt;/em&gt; and ABC News agreed that the growth in popularity of herbal medicines poses problems for physicians and patients.&lt;/p&gt;
&lt;p&gt;&quot;Because these remedies are &apos;natural,&apos; their potential dangers are not considered the same way they would be if they were medication,&quot; commented Suzanne Steinbaum, MD, a cardiologist at Lenox Hill Hospital in New York City, in an e-mail.&lt;/p&gt;
&lt;p&gt;&quot;For many reasons, patients tend not to disclose to their doctors if they are taking herbal remedies, including fear that their doctors won&apos;t approve or they will be told to stop them,&quot; Steinbaum added. &quot;This lack of knowledge and full-disclosure, for some, might be a fatal omission.&quot;&lt;/p&gt;
&lt;p&gt;Jahangir and colleagues reviewed nearly 90 publications that have addressed herbal or complementary therapies and cardiovascular effects since 1966.&lt;/p&gt;
&lt;p&gt;Their &lt;em&gt;JACC&lt;/em&gt; article listed 15 common herbal medicines known to interact adversely with conventional cardiovascular drugs.&lt;/p&gt;
&lt;p&gt;In many cases, the herbal products compete with the regular medicines for the same drug-metabolizing cytochrome P450 enzymes, potentiating the latter&apos;s effects. In other cases, the herbal products have their own cardiovascular effects.&lt;/p&gt;
&lt;p&gt;Many physicians already know that grapefruit juice occupies the CYP3A4 enzyme, leading to slower-than-expected metabolism and, therefore, higher blood levels of a host of pharmaceuticals.&lt;/p&gt;
&lt;p&gt;These include the statins, calcium channel antagonists, several common anti-arrhythmic drugs, and the angiotensin receptor blocker irbesartan (Avapro), Jahangir and colleagues noted.&lt;/p&gt;
&lt;p&gt;Garlic is one of several common herbal remedies with specific cardiovascular effects in its own right (others include ginkgo biloba, ginseng, and saw palmetto). Garlic inhibits platelet aggregation and thus can lead to increased bleeding risks when combined with aspirin, clopidogrel (Plavix), or warfarin (Coumadin), the researchers noted.&lt;/p&gt;
&lt;p&gt;The Mayo group identified 10 herbal products that increase bleeding risks with anticoagulant and antiplatelet drugs, as well as 14 that can induce arrhythmias.&lt;/p&gt;
&lt;p&gt;In all, Jahangir and colleagues listed 27 herbal products that patients with cardiovascular diseases would do well to avoid. These include such common and harmless-seeming products as green tea, capsicum pepper, licorice, and kelp, as well as grapefruit juice and garlic.&lt;/p&gt;
&lt;p&gt;&quot;We need to check with our patients what type of products they are using, to identify these potential interactions,&quot; Jahangir told &lt;em&gt;MedPage Today&lt;/em&gt;.&lt;/p&gt;
&lt;p&gt;He cited the previously reported figure of 100,000 deaths annually from drug interactions, adding, &quot;We don&apos;t even know how many of these are due to use of compounds that we are not aware that our patients are taking.&quot;&lt;/p&gt;
&lt;p&gt;Jahangir said he was surprised, in preparing the review, at the scale of hebal medicine use in the U.S.&lt;/p&gt;
&lt;p&gt;He and his colleagues found data from the 1990s suggesting that more patients consult complementary and alternative medicine providers than regular physicians.&lt;/p&gt;
&lt;p&gt;The total annual out-of-pocket expenditure on complementary and alternative medicine services and products also was greater than for conventional physician services.&lt;/p&gt;
&lt;p&gt;&quot;The surprise for me was . . . how much people are willing to spend on a type of therapy which has not shown, in any scientific way, to be effective or safe,&quot; Jahangir said.&lt;/p&gt;
&lt;p&gt;He added that the trend may reflect shortcomings of the conventional medical system.&lt;/p&gt;
&lt;p&gt;&quot;What is the reason people are going there? Is it because there is some unmet type of need that we are not recognizing as practitioners of conventional medicine?&quot;&lt;/p&gt;
&lt;p&gt;Jahangir said it may be that physicians aren&apos;t spending enough time with patients to understand their true needs. He said it appears that, &quot;despite the advancement in our technology and new medicines, there is a demand for alternative therapies that is increasing.&quot;&lt;/p&gt;
&lt;p&gt;He recommended that, in addition to asking patients in detail about herbal and other alternative therapies they may be using, physicians should educate themselves on what these therapies purport to do and what is known about their real biological effects.&lt;/p&gt;
&lt;p&gt;The &lt;a href=&quot;http://nccam.nih.gov&quot; mce_href=&quot;http://nccam.nih.gov&quot; target=&quot;_blank&quot;&gt;National Center for Complementary and Alternative Medicine&lt;/a&gt; at the National Institutes of Health is a good starting point for such information, both for physicians and for patients, Jahangir said.&lt;/p&gt;
&lt;p&gt;Lenox Hill&apos;s Steinbaum said it was important that conventional physicians &quot;become more open-minded and accepting&quot; of alternative medicine, if only because so many of their patients are already practicing it.&lt;/p&gt;
&lt;p&gt;David Meyerson, MD, JD, a Johns Hopkins University cardiologist, told &lt;em&gt;MedPage Today&lt;/em&gt; and ABC News in an e-mail that he advises patients to limit their use of &quot;unstudied and unproven and FDA-unregulated herbal medications.&quot;&lt;/p&gt;
&lt;p&gt;&quot;It&apos;s unfortunately very big business, and potential drug interactions and potential harmful effects abound,&quot; he wrote.&lt;/p&gt;
&lt;p&gt;But another physician criticized the Mayo physicians&apos; emphasis on adverse effects in their review.&lt;/p&gt;
&lt;p&gt;&quot;For many of products listed, evidence for side effects seems to be minimal,&quot; Scott Grundy, MD, of the University of Texas Southwestern Medical Center in Dallas, argued in an e-mail.&lt;/p&gt;
&lt;p&gt;He agreed that the efficacy and safety of such drugs remains largely unproven, but added, &quot;It is mainly for these reasons that they cannot be recommended for use.&quot;&lt;/p&gt;
&lt;p&gt;Creating alarm about side effects &quot;may not be the appropriate way to discourage their use,&quot; Grundy said.&lt;/p&gt;

                     score="0.009"
                     href="http://www.medpagetoday.com/Endocrinology/Diabetes/tb/18233?impressionId=1265817384416"
                     
      When it comes to predicting chronic disease, body mass index doesn&apos;t tell the whole story, according to a population-based study that found elevated risk with obesity and other metabolic risk factors independently.&lt;br&gt;
&lt;br&gt;Metabolically-healthy obese people tended toward being at least twice as likely to develop multiple metabolic risk factors and diabetes as healthy, normal weight individuals over the subsequent 3.5 years of a study led by Sarah Appleton, a postgraduate student at the University of Adelaide, Australia.&lt;br&gt;
&lt;br&gt;However, normal weight individuals with metabolic risk factors  --  a group the researchers called &quot;metabolically obese&quot;  --  were at greater risk, she told attendees at the International Congress on Abdominal Obesity in Hong Kong, a conference sponsored by the International Chair on Cardiometabolic Risk.&lt;br&gt;
&lt;br&gt;Overall, just 4.1% of the 3,743 adults in the population-based, North West Adelaide Health Study were in the normal body mass index range at baseline but had at least two of the following metabolic risk factors:&lt;ul&gt; &lt;li&gt;Triglyceride levels of 1.7 mmol/L or greater&lt;/li&gt; &lt;li&gt;HDL cholesterol under 1.0mmol/L for men or 1.3 mmol/L for women&lt;/li&gt; &lt;li&gt;Blood pressure of 130/85 mm Hg or higher&lt;/li&gt; &lt;li&gt;A fasting plasma glucose of at least 5.6mmol/L or self-reported diabetes&lt;/li&gt; &lt;li&gt;Treatment for any of these disorders &lt;/li&gt; &lt;/ul&gt;
&lt;p&gt;Although free of cardiovascular disease when they entered the study through a random population sample of the northwest region of Adelaide, after a mean of 3.5 years of follow-up, this group was 2.48 times at risk of incident cardiovascular disease or stroke events (95% CI 1.1 to 5.4).&lt;/p&gt;
&lt;p&gt;Compared with metabolically-healthy, normal weight individuals, those with metabolic risk factors tended to be&lt;strong&gt; &lt;/strong&gt;3.27 times as likely to develop diabetes (&lt;em&gt;P&lt;/em&gt;=0.07).&lt;/p&gt;
&lt;p&gt;Identifying these individuals for prevention efforts may require less emphasis on BMI and increased surveillance of central obesity in primary care, the researchers told the congress.&lt;/p&gt;
&lt;p&gt;&quot;The problem with BMI is it doesn&apos;t tell you where the fat is,&quot; Appleton added in an interview. &quot;Visceral fat is really bad for you.&quot;&lt;/p&gt;
&lt;p&gt;Obese individuals without multiple metabolic risk factors at baseline comprised a larger group (12.1%).&lt;/p&gt;
&lt;p&gt;They were more likely to be middle age, live in a disadvantaged neighborhood, have smoked at some point, and get less exercise than their metabolically similar, but slimmer peers.&lt;/p&gt;
&lt;p&gt;Over the subsequent 3.5 years, they were 2.82 times more likely to develop more than one metabolic risk factor than metabolically-healthy, normal weight individuals (95% CI 2.0 to 4.0).&lt;/p&gt;
&lt;p&gt;The metabolically-normal obese also tended to be 2.36 times more likely to develop diabetes (95% CI 0.8 to 7.1). On the other hand, their risk of cardiovascular disease wasn&apos;t elevated, &quot;which likely related to the younger age of that group,&quot; Appleton told &lt;em&gt;MedPage Today&lt;/em&gt;.&lt;/p&gt;
&lt;p&gt;Notably, abdominal obesity as determined by a waist circumference of 80 cm and over for men or 95 cm and greater for women was 6.1 times more likely among metabolically healthy individuals if their BMI was in the obese versus normal range.&lt;/p&gt;
&lt;p&gt;But those who were in the normal BMI range were 2.2-fold more likely to be overweight or obese according to waist circumference if they had metabolic risk factors, which was statistically significant as well and likely contributed to the health risks they faced over the short-term future, Appleton said.&lt;/p&gt;
&lt;p&gt;Maintenance of metabolic health in the obese population was more likely for younger individuals (OR 2.83 for age 40 or younger, 95% CI 1.1 to 7.6) and those who were at least moderately physically active (OR 2.04, 95% CI 1.01 to 4.1).&lt;/p&gt;
&lt;p&gt;Appleton noted that these findings generally fit with data from the U.S. National Health Assessment Survey and Examination.&lt;/p&gt;
&lt;p&gt;Regardless of whether patients have abdominal obesity, BMI obesity, or other metabolic risk factors, the solution is likely similar  --  improved diet and exercise, she said.&lt;/p&gt;

      For heart disease patients, omega-3 fatty acids may protect against morbidity and mortality by slowing biological aging, researchers say.&lt;br&gt;
&lt;br&gt;Patients who had the highest omega-3 fatty acid blood levels also had telomeres that shortened at a significantly slower rate than patients with lower intake, Ramin Farzaneh-Far, MD, of the University of California San Francisco, and colleagues reported in the Jan. 20 &lt;em&gt;JAMA&lt;/em&gt;.&lt;br&gt;
&lt;br&gt;Patients in the lowest quartile of omega-3 fatty acid blood levels had the fastest rate of telomere shortening over five years: 0.13 telomere-to-single-copy gene ratio (95% CI 0.09 to 0.17).&lt;br&gt;
&lt;br&gt;Those who had the highest omega-3 fatty acid blood levels had the slowest rate of telomere shortening: 0.05 telomere-to-single copy ratio (95% CI 0.02 to 0.08, &lt;em&gt;P&lt;/em&gt;&amp;lt;0.001).&lt;/p&gt;
&lt;p&gt;Telomeres are the protective caps at the end of chromosomes that reveal how biological stress ages a person.&lt;p&gt;&lt;/p&gt;
&lt;p&gt;&quot;Patients with the highest levels of omega-3 fish oils were found to display the slowest decrease in telomere length, whereas those with the lowest levels of omega-3 fish oils in the blood had the fastest rate of telomere shortening,&quot; Farzaneh-Far said. &quot;This suggests that these patients were aging faster than those with higher fish oil levels.&quot;&lt;/p&gt;
&lt;p&gt;They said omega-3s may protect against oxidative stress, or increase the activity of the telomerase enzyme, which would decrease telomere shortening by creating more accurate telomere copies.&lt;/p&gt;
&lt;p&gt;But some cardiologists were quick to point out that the results are preliminary and need to be replicated before physicians can use them in practice.&lt;/p&gt;
&lt;p&gt;Since the study was observational and couldn&apos;t prove cause-and-effect, &quot;we don&apos;t really know whether ingestion of omega-3 fatty acids resulted in this &apos;benefit,&apos;&quot; Steven E. Nissen, MD, of the Cleveland Clinic, noted in an e-mail. &quot;It remains entirely possible that individuals who consume more fish also have other favorable healthy habits.&quot;&lt;/p&gt;
&lt;p&gt;Nissen also pointed out that the study was not randomized to compare fish oil directly with a placebo treatment, and cautioned that &quot;the relationship between telomere shortening and cardiovascular health is not well established.&quot;&lt;/p&gt;
&lt;p&gt;Studies have shown that omega-3s appear to be effective for patients with coronary artery disease. Yet the underlying mechanisms are not well understood. Some researchers think it may have something to do with anti-inflammatory, triglyceride-lowering, antihypertensive, antiplatelet, or antiarrhythimic effects.&lt;/p&gt;
&lt;p&gt;Research has shown that the length of telomeres  --  chromosome caps that have long been compared to the plastic ends of shoelaces  --  may be a marker of biological age. Biological age is independent of chronological age, and takes into account genetic and environmental stressors that may wreak havoc on cells.&lt;/p&gt;
&lt;p&gt;Since there&apos;s been increasing evidence that omega-3s exert direct effects on aging and age-related diseases, the researchers decided to investigate them as a potential mechanism for protective effects in heart patients.&lt;/p&gt;
&lt;p&gt;So they conducted a prospective cohort study of 608 patients in California with stable coronary artery disease. Patients were recruited from the Heart and Soul Study between September 2000 and December 2002.&lt;/p&gt;
&lt;p&gt;They were followed for five years, and the researchers assessed telomere length of their leukocytes at baseline and again at the end of follow-up.&lt;/p&gt;
&lt;p&gt;&quot;By measuring telomere length at two different times,&quot; Farzaneh-Far said, &quot;we were able to see the speed at which the telomers are shortening and that gives us some indication of how rapidly the biological aging process is taking place in these patients.&quot;&lt;/p&gt;
&lt;p&gt;The researchers found that baseline omega-3 fatty acid levels were positively correlated with changes in telomere length over five years (&lt;em&gt;P&lt;/em&gt;=0.001).&lt;/p&gt;
&lt;p&gt;The relationships remained after controlling for potential confounders including demographics, blood pressure, serum lipids, and inflammatory biomarkers.&lt;/p&gt;
&lt;p&gt;The researchers noted that each standard-deviation increase in fatty acid levels was associated with a 32% reduction in the odds of telomere shortening (95% CI 0.47 to 0.98).&lt;/p&gt;
&lt;p&gt;So how do omega-3s stop telomeres from getting smaller?&lt;/p&gt;
&lt;p&gt;They may protect against oxidative stress, which is a major driver of telomere shortening and aging. Or, fatty acids may increase the activity of the enzyme telomerase, which can result in more accurate copying and hence, longer telomeres, the researchers suggested.&lt;/p&gt;
&lt;p&gt;The researchers agreed that the study was limited by its observational nature, which leaves no room for definitive conclusions about causality. Also, they only measured telomere length in leukocytes, which means the findings may not translate to other cell types, including myocardial or endothelial cells.&lt;/p&gt;
&lt;p&gt;Researchers who were not involved in the study noted that omega-3s have been shown to have effects on other factors that contribute to heart disease risk.&lt;/p&gt;
&lt;p&gt;&quot;Omega-3 fatty acids have a potent positive impact on lipids that circulate in the blood stream and damage the heart,&quot; said Cam Patterson, MD, of the University of North Carolina Chapel Hill McAllister Heart Institute. &quot;The effects of omega-3 fatty acids on lipids are still the best advertisement for their use to prevent heart disease.&quot;&lt;/p&gt;
&lt;p&gt;Merle Myerson, MD, of Columbia University, agreed. &quot;[The researchers] don&apos;t mention that omega-3 fatty acids lower triglycerides and non-HDL cholesterol, and stabilize cell membranes  --  all of which may reduce risk for coronary artery disease and sudden cardiac death.&quot;&lt;/p&gt;
&lt;p&gt;Myerson said the findings need to be replicated in future studies.&lt;/p&gt;
&lt;p&gt;While their study may not have implications for intake of omega-3s among the general population, the researchers said it upholds recommendations for patients with heart disease.&lt;/p&gt;
&lt;p&gt;&quot;The results of our study underscore the recommendations of the American Heart Association, that patients with known coronary artery disease should be getting at least one gram a day of omega-3 fish oil,&quot; Farzaneh-Far said.&lt;/p&gt;

      &lt;p&gt;HOLLYWOOD, Fla.  --  Contrary to expectations, women who undergo last-ditch, minimally-invasive procedures to open small blood vessels in the leg  --  and forestall amputation  --  generally have better outcomes than men, researchers reported here.&lt;/p&gt;
&lt;p&gt;Overall, 87.5% of women who underwent the infragenicular endoscopic angioplasty avoided amputation for at least two years, compared with 82.9% of the men who were similarly treated (&lt;em&gt;P&lt;/em&gt;=0.041), according to Tejas Shah, MD, of Mount Sinai Medical Center in New York City.&lt;/p&gt;
&lt;p&gt;&quot;This study is the first to compare the outcomes of men and women being treated for blocked lower-leg arteries with endovascular therapy,&quot; Shah said at the International Symposium on Endovascular Therapy (ISET). &quot;The results suggest endovascular therapy should be strongly considered in women with blocked arteries below the knee.&quot;&lt;/p&gt;
&lt;p&gt;In many endovascular procedures, women tend to do worse then men, generally because they tend to have smaller blood vessels. But in this study, involving the smallest leg blood vessels, the opposite occurred. &quot;We really don&apos;t have any good reason why there should be this gender difference,&quot; Shah said.&lt;/p&gt;
&lt;p&gt;&quot;What made this difference significant,&quot; Shah told &lt;em&gt;MedPage Today&lt;/em&gt;, &quot;was that the women in the study, overall, were at significantly greater risk of amputation than the male patients.&quot; He said that about 22.3% of men underwent treatment for claudication, compared with 12.3% of the women, but 77.7% of men were being treated for limb-threatening conditions compared with 87.7% of women.&lt;/p&gt;
&lt;p&gt;The retrospective study involved review of angioplasties, stenting, and atherectomies performed on 152 men and 125 women at Mount Sinai between July 1999 and November 2009.&lt;/p&gt;
&lt;p&gt;When adjusted for comorbidities, women treated for tibial lesions with concurrent proximal disease had higher 24-month primary patency rates compared with men.&lt;/p&gt;
&lt;p&gt;Some 46% of treated leg arteries in women remained open, compared with 30% (&lt;em&gt;P&lt;/em&gt;=0.016) in men. Shah said that a subanalysis of isolated tibial lesions indicated that 50% of women achieved 24-month primary patency rates, compared with 28.8% of men (&lt;em&gt;P&lt;/em&gt; =0.002).&lt;/p&gt;
&lt;p&gt;On the downside, women experienced higher rates of blood clots forming at the access site of the treatment (9% versus 0.6%, &lt;em&gt;P&lt;/em&gt;&amp;lt;.0001). Clotting, typically treated with blood thinners, may require a longer stay in the hospital (&lt;em&gt;P&lt;/em&gt;&amp;lt;0.0001).&lt;/p&gt;
&lt;p&gt;&quot;In both men and women it is hard to keep these smaller leg blood vessels open,&quot; said Constantino Pe&amp;#241;a, MD, medical director of vascular imaging at Baptist Cardiac &amp;amp; Vascular Institute, Miami.&lt;/p&gt;
&lt;p&gt;&quot;It might be possible that women do better because of their hormone status. But we need to do prospective clinical trials to see if we can determine what factor is involved in making the procedure work better for women.&quot;&lt;/p&gt;
