      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;

      &lt;p&gt;FORT LAUDERDALE  --  Avoiding femoral artery cannulization during cardiac surgery might eliminate some of the rare but potentially catastrophic aortic dissections that occur during the procedure, researchers said here.&lt;/p&gt;
&lt;p&gt;Doctors identified the femoral location as an increased risk factor in an analysis of records from the Society of Thoracic Surgeons&apos; national database of more than 2.2 million cardiac surgeries. That search yielded 1,294 incidents of aortic dissection.&lt;/p&gt;
&lt;p&gt;&quot;Prevention is the key,&quot; Matthew Williams, MD, of the University of Louisville, said at the annual meeting of the Society of Thoracic Surgeons here.&lt;/p&gt;
&lt;p&gt;Williams and colleagues reported that aortic dissection occurs in only 0.06% of cardiac surgeries but accounts for almost one percent of perioperative deaths.&lt;/p&gt;
&lt;p&gt;&quot;Aortic dissection is a low frequency but catastrophic event,&quot; Williams said, noting that 48% of aortic dissections during surgery prove fatal. Some 9% of the survivors suffer strokes and 14% experience kidney failure.&lt;/p&gt;
&lt;p&gt;He recalled becoming interested in the research after one of his patients, a woman, experienced aortic dissection during a procedure. &quot;She walked out of the hospital,&quot; he said.&lt;/p&gt;
&lt;p&gt;He told &lt;em&gt;MedPage Today&lt;/em&gt; that &quot;the incidence of these aortic dissections is so small that only a large database project such as this one could possibly get at these cases.&quot;&lt;/p&gt;
&lt;p&gt;According to his presentation materials, researchers created a logistic regression model based on 2004-2007 STS data. The analysis turned up nine significant risk factors, including femoral cannulization, preoperative steroids, and Asian race. Diabetes appeared to be protective.&lt;/p&gt;
&lt;p&gt;When aortic dissection occurs during surgery, Williams said, doctors generally stop the operation and attempt to restart it by cannulization in another area.&lt;/p&gt;
&lt;p&gt;He said he has considered femoral access as a last resort and prefers either central aortic cannulization or axial cannulization.&lt;/p&gt;
&lt;p&gt;He said improving outcomes and identifying what causes aortic dissection in these surgical cases may require changes and updates in the information captured by the database. He said a clinical trial would require so many patients that it would not be practical.&lt;/p&gt;
&lt;p&gt;Aubrey Galloway, MD, of the New York University School of Medicine, who was the discussant for Williams&apos; talk, said that the imprecise nature of the way the data are gathered might have misidentified the femoral access point as a culprit procedure.&lt;/p&gt;
&lt;p&gt;&quot;It may be that femoral access was employed in response to another dissection site,&quot; he said.&lt;/p&gt;
&lt;p&gt;Williams responded that by tweaking the information acquired by the database it might be possible to better determine these associations.&lt;/p&gt;

                     score="-0.003"
                     href="http://www.medpagetoday.com/Cardiology/PeripheralArteryDisease/tb/18051?impressionId=1265746902217"
                     
      &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;
