      Having less abdominal fat but more leg fat may play a role in maintaining metabolic health in obese women, but not in heavy men, researchers found.&lt;br&gt;
&lt;br&gt;Metabolically healthy obese women had significantly more leg fat compared with metabolically unfit women, and smaller waist circumference (&lt;em&gt;P&lt;/em&gt;&amp;lt;0.05), Sarah Appleton, a postgraduate student at the University of Adelaide in Australia, and colleagues reported at the International Congress on Abdominal Obesity in Hong Kong.&lt;br&gt;
&lt;br&gt;When there&apos;s no significant differences in total body fat, the high levels of leg fat but low levels of central fat &quot;makes you think this is a protective factor against developing metabolic complications of their obesity, including diabetes,&quot; Appleton told &lt;em&gt;MedPage Today&lt;/em&gt;.&lt;/p&gt;
&lt;p&gt;Smaller studies have shown that metabolically healthy obese patients have less visceral fat compared with insulin-resistant obese patients, suggesting these may be protective factors that limit the development of metabolic disease.&lt;/p&gt;
&lt;p&gt;On the other hand, normal-weight patients with cardiometabolic risk factors, who are labeled as &quot;metabolically obese,&quot; have higher abdominal adiposity compared with metabolically healthy normal-weight patients. They&apos;re also at increased risk for diabetes and heart disease.&lt;/p&gt;
&lt;p&gt;To examine the relationship, the researchers conducted dual energy X-ray absorptiometry (DEXA) scans of body composition in 1,604 patients who were over age 50 and participated in the North West Adelaide Health Study. They were stratified in four categories: metabolically obese normal-weight, metabolically healthy normal weight, metabolically healthy obese, and metabolically unfit obese.&lt;/p&gt;
&lt;p&gt;Metabolic obesity was defined by having two or more metabolic risk factors including high triglycerides, low HDL cholesterol, high blood pressure, high fasting plasma glucose, or diabetes.&lt;/p&gt;
&lt;p&gt;The researchers also measured waist circumference.&lt;/p&gt;
&lt;p&gt;They found that among normal-weight women, the metabolically obese had significantly more total fat and more trunk fat compared with those who were metabolically healthy (&lt;em&gt;P&lt;/em&gt;&amp;lt;0.05). There were no differences in waist circumference or lean mass.&lt;/p&gt;
&lt;p&gt;Among obese women, the metabolically healthy had no significant differences in total body fat, compared with the metabolically unfit. But they had significantly more leg fat, a smaller waist circumference, and the same amounts of lean mass.&lt;/p&gt;
&lt;p&gt;&quot;We would have expected to see that metabolically healthy obese ladies would have more leg fat, but also more lean mass and less central fat, since this combination is protective against developing diabetes,&quot; Appleton said, &quot;but we didn&apos;t see that related to lean mass, which was surprising.&quot;&lt;/p&gt;
&lt;p&gt;Normal-weight men who had metabolic problems had significantly more total fat and trunk (chest and abdominal) fat than metabolically healthy ones, but no differences in lean mass.&lt;/p&gt;
&lt;p&gt;And for obese men, there were no significant differences between the metabolically fit and unfit, which &quot;was a surprise,&quot; Appleton said.&lt;/p&gt;
&lt;p&gt;&quot;Men generally have much less fat and more lean mass,&quot; she added. &quot;Women are the other way around, so maybe it&apos;s not so surprising to see these effects specifically in women.&quot;&lt;/p&gt;
&lt;p&gt;The researchers did find that among all overweight patients, both male and female, metabolic health was associated with significantly lower waist circumference.&lt;/p&gt;
&lt;p&gt;&quot;We know specifically that fat around the abdomen is dangerous because it can drain into your blood very easily and have direct effects on organs including the liver and pancreas,&quot; Appleton said. &quot;The theory is that distribution of fat and maybe an alternative inflammatory profile protects obese ladies from developing the metabolic consequences you&apos;d expect to see in people who are obese.&quot;&lt;/p&gt;
&lt;p&gt;Appleton said the study may have implications for clinical practice, adding that physicians should assess both BMI and waist circumference to determine disease risk. Moreover, physicians &quot;need to focus on healthy weight loss in a way that protects lean mass but also reduces dangerous fat deposits including central adiposity.&quot;&lt;/p&gt;
&lt;p&gt;It also goes to show that &quot;just because somebody looks thin,&quot; Appleton added, &quot;doesn&apos;t mean they&apos;re healthy.&quot;&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;

Pe&amp;#241;a reported financial relationships with Bard and Medtronic.&lt;/p&gt;&lt;/div&gt;&lt;div style=&quot;clear:both;&quot;&gt;&lt;/div&gt;
