                     href="http://www.medpagetoday.com/Washington-Watch/Washington-Watch/tb/18388?impressionId=1265758585862"
                     
      &lt;p&gt;Representative John P. Murtha (D-Pa.), 77, long-time chairman of the House Appropriations Subcommittee on Defense, died yesterday afternoon from complications following a planned laparoscopic cholecystectomy, according to a statement from the congressman&apos;s office.&lt;/p&gt;
&lt;p&gt;He had been admitted to the intensive care unit at Virginia Hospital Center in Arlington on Jan. 31, days after surgeons at the National Naval Medical Center in Bethesda, Md., accidentally nicked his intestine during the operation, according to a report in &lt;em&gt;The Washington Post&lt;/em&gt;.&lt;/p&gt;
&lt;p&gt;In that same report, Rep. Bob Brady (D-Pa.), a close friend of Murtha&apos;s, said the congressman developed an infection and fever.&lt;/p&gt;
&lt;p&gt;Citing a request for privacy from the Murtha family and patient privacy laws, a spokesperson for the National Naval Medical Center declined to provide information on the operation.&lt;/p&gt;
&lt;p&gt;In a statement, Virginia Hospital Center said Murtha died &quot;despite aggressive critical care interventions.&quot;&lt;/p&gt;


  &lt;p&gt;Mark Malangoni, MD, surgeon-in-chief at MetroHealth Medical Center in Cleveland, told &lt;em&gt;MedPage Today&lt;/em&gt; that serious complications, including bowel damage and death, are not common following cholecystectomy. More complicated patients, such as the obese and diabetics, have a greater risk of complications and of a switch to an open procedure.&lt;/p&gt;
    &lt;p&gt;Death is extremely rare in healthy individuals, occurring in no more than one per 1,000 patients, according to the American College of Surgeons (ACS).
    &lt;p&gt;More common, but still infrequent, are bleeding and leakage of bile, both of which can be treated fairly easily, said Malangoni, a regent of the ACS.&lt;/p&gt;


&lt;p&gt;When the bowel is damaged, as reportedly occurred in Murtha&apos;s case, it typically occurs in two ways -- either from a sharp injury when the trocars used for a laparoscopic procedure are inserted or from a cautery burn.
    &lt;p&gt;Both types of injury can go unnoticed by the surgeon and may not become apparent for days after the operation, Malangoni said.&lt;p&gt;
    &lt;p&gt;Although he did not know the details of Murtha&apos;s case, Malangoni said a patient would usually be admitted right away, at least overnight, if the surgeon realized that an injury had occurred. The procedure likely would have switched from a laparoscopic one to an open one as well.&lt;/p&gt;


&lt;p&gt;A 2009 Cochrane Review comparing laparoscopic versus open cholecystectomy for patients with symptomatic cholecystolithiasis found no difference in mortality in 38 trials. No patients died in the laparoscopic group and only 0.09% died in the open group.&lt;/p&gt;
&lt;p&gt;Severe complications were reported in 2.2% of the laparoscopic patients and 6.8% of the open patients.&lt;/p&gt;


 &lt;p&gt;Malangoni said most surgeons become experienced with performing laparoscopic cholecystectomies before completing their residency; most will perform 40 or 50 by the end of training.&lt;p&gt;
    &lt;p&gt;&quot;It is a very common operation, so once out into practice, most general surgeons are doing dozens of these each year,&quot; he said. &quot;So your experience comes about pretty quickly.&quot;
    &lt;p&gt;It is unclear how much experience Murtha&apos;s surgeon had.&lt;/p&gt;

&lt;p&gt;Murtha had recently become the longest serving member of Congress in Pennsylvania state history.&lt;/p&gt;
&lt;p&gt;First elected in 1974, Murtha, a former Marine, was the first Vietnam War combat veteran to serve in Congress, and he served as an advocate for the military throughout his career. He was also a prominent critic of the Iraq War.&lt;/p&gt;
&lt;p&gt;Murtha is survived by his wife, Joyce, and three children.&lt;/p&gt;

                     score="0.009"
                     href="http://www.medpagetoday.com/CriticalCare/InfectionControl/tb/18308?impressionId=1265758585862"
                     
      Catheter-related infections aren&apos;t inevitable in the ICU, according to a quality initiative that maintained rates at nearly zero for three years in Michigan hospitals.&lt;br&gt;
&lt;br&gt;The maintenance phase, after initial implementation of low-tech measures such as handwashing and removal of unneeded catheters, saw no rebound in catheter-related infections, Peter J. Pronovost, MD, PhD, of Johns Hopkins, and colleagues reported online in &lt;em&gt;BMJ&lt;/em&gt;.&lt;br&gt;
&lt;br&gt;The first 18 months of their &lt;a href=&quot;http://www.medpagetoday.com/InfectiousDisease/GeneralInfectiousDisease/4771&quot; mce_href=&quot;http://www.medpagetoday.com/InfectiousDisease/GeneralInfectiousDisease/4771&quot; target=&quot;_blank&quot;&gt;Keystone ICU initiative&lt;/a&gt; dropped catheter-related interventions from a mean of 7.7 and median of 2.2 per 1,000 catheter days down to 1.3 and 0, respectively.&lt;br&gt;
&lt;br&gt;At the 36 month mark, infection rates remained almost nil, at a mean of 1.1 and median of 0 per 1,000 catheter days.&lt;p&gt;&lt;/p&gt;
&lt;p&gt;&quot;For the most part, hospitals view these infections as inevitable, as the cost of doing business, that patients are too sick, that these can&apos;t be prevented,&quot; Pronovost told &lt;em&gt;MedPage Today&lt;/em&gt;. &quot;That&apos;s just not true.&quot;&lt;/p&gt;
&lt;p&gt;Catheter-related infections are the number one cause of preventable death in hospitals and ICUs, ahead of even ventilator-related pneumonia, he noted.&lt;/p&gt;
&lt;p&gt;The changes seen at the 90 Michigan ICUs that stayed with the catheter-related infection initiative were impressive, representing one of the largest and longest improvements the field has seen.&lt;/p&gt;
&lt;p&gt;Often, quality initiatives fail on durability after the study funding and resources disappear, and hospitals are left on their own, Pronovost noted.&lt;/p&gt;
&lt;p&gt;&quot;If you push you might get some effect, but then you stop pushing  --  in other words the external control goes away  --  and the performance goes right back down,&quot; he said in an interview. &quot;It can&apos;t just be the stick that drives it.&quot;&lt;/p&gt;
&lt;p&gt;The intervention started with 103 ICUs that implemented strategies to reduce rates of catheter-related bloodstream infections rates over 18 months, with measurement and feedback of infection rates.&lt;/p&gt;
&lt;p&gt;The strategies aimed at improving execution of five evidence-based recommendations, as follows: &lt;ul&gt; &lt;li&gt;Hand washing before insertion of the catheter&lt;/li&gt; &lt;li&gt;Using gowns and full barrier precautions at catheter insertion&lt;/li&gt; &lt;li&gt;Cleaning the skin with chlorhexidine before catheter insertion&lt;/li&gt; &lt;li&gt;Avoiding the femoral site when possible&lt;/li&gt; &lt;li&gt;Removing unnecessary catheters&lt;/li&gt; &lt;/ul&gt;&lt;/p&gt;
&lt;p&gt;Then, over the subsequent 18-month maintenance period, ICU teams were instructed to integrate this intervention into staff orientation, to collect monthly data from hospital infection control staff, and to report infection rates to physicians and others.&lt;/p&gt;
&lt;p&gt;Along with the sustained reduction in overall catheter-related infections, the researchers found a prolonged reduction in bloodstream infections that was significant during all study periods, compared to baseline.&lt;/p&gt;
&lt;p&gt;Rates decreased from a mean of 7.7 and median 2.7 of per 1,000 catheter days at baseline to 1.3 and 0, respectively, at 16 to 18 months after implementation. They remained at 1.1 and 0 at months 34 to 36 (-1% versus 18 months, 95% CI -9% to +7%).&lt;/p&gt;
&lt;p&gt;ICU teams interviewed attributed the continuously low rates to five factors: &lt;ul&gt; &lt;li&gt;Continued feedback on infection data&lt;/li&gt; &lt;li&gt;Improvements in safety culture as part of the project&lt;/li&gt; &lt;li&gt;An &quot;unremitting belief in the preventability of bloodstream infections&quot;&lt;/li&gt; &lt;li&gt;Involvement of senior leaders&lt;/li&gt; &lt;li&gt;A noncompetitive, shared goal to reduce infection rates throughout the state&lt;/li&gt; &lt;/ul&gt;&lt;/p&gt;
&lt;p&gt;Of these, Pronovost called culture change in the ICUs the key factor to sustainability, although the researchers cautioned that which aspects contributed were not formally evaluated.&lt;/p&gt;
&lt;p&gt;They said they could not determine the impact incentive payments from Blue Cross Blue Shield of Michigan to hospitals that continued their participation  --  payments that were based on performance thresholds in subsequent years.&lt;/p&gt;
&lt;p&gt;Pronovost&apos;s team is now working to implement the quality initiative state-by-state nationwide, supported by the Agency for Healthcare Research and Technology.&lt;/p&gt;
&lt;p&gt;&quot;It seems absurd that this wouldn&apos;t be in every hospital in the country,&quot; he said in an interview. &quot;It&apos;s worked on a large scale, it&apos;s exceedingly cheap, there&apos;s no fancy technology.&quot;&lt;/p&gt;
&lt;p&gt;Success isn&apos;t only for community hospitals, Pronovost emphasized.&lt;/p&gt;
&lt;p&gt;Large, often academic, medical centers frequently express the conviction that their sicker, more complex ICU population wouldn&apos;t produce the same results, that their infections truly are inevitable, he said.&lt;/p&gt;
&lt;p&gt;&quot;To them I say, Not so,&quot; he told &lt;em&gt;MedPage Today&lt;/em&gt;. &quot;We have shown at Johns Hopkins, at the University of Michigan, at Pittsburgh, using a similar but different approach, at Tufts  --  many large academic medical centers have had dramatic reductions of these infections.&quot;&lt;/p&gt;

                     href="http://www.medpagetoday.com/HematologyOncology/ColonCancer/tb/18164?impressionId=1265758585862"
                     
      Patients 65 and older are as suitable as younger individuals for CT colonography, said researchers conducting a large retrospective study.&lt;br&gt;
&lt;br&gt;Advanced neoplasias were detected with CT colonography  --  often called &quot;virtual colonoscopy&quot;  --  in older patients at more than double the rate in the general screening population, reported David H. Kim, MD, of the University of Wisconsin in Madison, Wis., and colleagues in the February issue of &lt;em&gt;Radiology&lt;/em&gt;.&lt;br&gt;
&lt;br&gt;They found that 7.6% of older patients had advanced neoplasias, compared with 3.2% of all patients screened in the university&apos;s clinic (&lt;em&gt;P&lt;/em&gt;&amp;lt;0.001).&lt;/p&gt;
&lt;p&gt;On the basis of this and other findings in 577 individuals 65 and older versus the entire group of 3,120 patients undergoing the procedure, Kim and colleagues concluded that &quot;CT colonography performance is maintained in an older cohort.&quot;&lt;/p&gt;
&lt;p&gt;&quot;Overall, the observations from this clinical experience confirm that CT colonography may be a valuable screening modality in the older population,&quot; they wrote.&lt;/p&gt;
&lt;p&gt;On the other hand, the study did not address several objections raised by the Centers for Medicare and Medicaid Services (CMS) in its decision last year to deny Medicare coverage for the procedure. (See &lt;a href=&quot;http://www.medpagetoday.com/PublicHealthPolicy/Medicare/14186&quot; mce_href=&quot;http://www.medpagetoday.com/PublicHealthPolicy/Medicare/14186&quot; target=&quot;_blank&quot;&gt;Medicare Finalizes Denial of Virtual Colonoscopy Coverage&lt;/a&gt;)&lt;/p&gt;
&lt;p&gt;CMS had pointed to relatively low sensitivity of CT colonography compared with optical colonoscopy in prospective trials, especially for small lesions.&lt;/p&gt;
&lt;p&gt;The agency also determined that CT colonography increased the costs of positive findings, since abnormalities in the CT scans must be confirmed with optical colonoscopy. In addition, CMS said there was no evidence to support claims that the less invasive imaging procedure would be more acceptable to patients and therefore would raise screening rates.&lt;/p&gt;
&lt;p&gt;The data analyzed by Kim and colleagues did not allow for calculations of false-negative rates or predictive values of positive or negative findings. Nor did the researchers report cost information.&lt;/p&gt;
&lt;p&gt;Mean age of their older cohort was 69.2 (SD 3.8). The oldest was 79.&lt;/p&gt;
&lt;p&gt;The researchers reported that 15.3% of the older patients were referred for optical colonoscopy on the basis of the CT results, compared with 7.9% of the overall screening group.&lt;/p&gt;
&lt;p&gt;Less than 4% of positive findings were determined to be false with the optical procedure (3.6% for polyps 6 to 10 mm in diameter, 2.1% for larger lesions).&lt;/p&gt;
&lt;p&gt;Of the 59 advanced neoplasias identified in the older patients, all but three were at least 10 mm in size.&lt;/p&gt;
&lt;p&gt;The scans also suggested abnormalities outside the colon in 89 (15.4%) patients. Of these, 45 received a full workup, which revealed substantial and previously unsuspected diagnoses in 21 cases  -- 18 were vascular aneurysms. The other three included one lung tumor, a femoral hernia, and a malrotation.&lt;/p&gt;
&lt;p&gt;Kim and colleagues reported that no &quot;substantial complications&quot; such as perforations or major hemorrhage occurred in the older patients, either with the CT scan or follow-up colonoscopy.&lt;/p&gt;
&lt;p&gt;They also indicated that the ratio of large to small neoplasias was similar in the older patients compared with their CT screening group as a whole. Histologic and morphologic findings were similar as well.&lt;/p&gt;
&lt;p&gt;The researchers cited the observational nature of the study, in which negative findings were not corroborated with optical colonoscopy, and its restriction to a single center as its main limitations.&lt;/p&gt;

                     href="http://www.medpagetoday.com/MeetingCoverage/ASCOGI/tb/18079?impressionId=1265758585862"
                     
      &lt;p&gt;ORLANDO  --  A novel blood test that measures CD24 protein levels may detect early colorectal cancer and precancerous adenomas, researchers found.&lt;/p&gt;
&lt;p&gt;The investigational assay had 78.4%% sensitivity and 86.8% specificity for distinguishing patients with colorectal adenoma or cancer from healthy controls in a study led by Sarah Kraus, PhD, of Tel Aviv Souraski Medical Center in Israel.&lt;/p&gt;
&lt;p&gt;Further validation for the biomarker would be needed before considering clinical use in surveillance, they cautioned here at the ASCO Gastrointestinal Cancers Symposium.&lt;/p&gt;
&lt;p&gt;But the results were exciting and could represent &quot;a very significant advance,&quot; commented Robert P. Sticca, MD, of the University of North Dakota in Grand Forks.&lt;/p&gt;
&lt;p&gt;&quot;It looks like it may be a very reliable marker for not only the early detection of colon cancer and even precancerous conditions, but also could be used for follow-up for patients who previously had cancer for recurrence,&quot; he said as moderator of a press briefing at which the results were discussed.&lt;/p&gt;
&lt;p&gt;Colorectal cancer screening is effective, with early detection and treatment shown to improve survival.&lt;/p&gt;
&lt;p&gt;However, colorectal cancer is often diagnosed at a late stage with poor prognosis, in part because of &lt;a href=&quot;http://www.medpagetoday.com/Gastroenterology/ColonCancer/10115&quot; mce_href=&quot;http://www.medpagetoday.com/Gastroenterology/ColonCancer/10115&quot; target=&quot;_blank&quot;&gt;poor uptake of colonoscopy&lt;/a&gt;, Kraus said at the press briefing.&lt;/p&gt;
&lt;p&gt;Unfortunately, there are no sufficiently accurate blood-based screening tests, he noted, although there have been &lt;a href=&quot;http://www.medpagetoday.com/MeetingCoverage/ECCO-ESMO/16057&quot; mce_href=&quot;http://www.medpagetoday.com/MeetingCoverage/ECCO-ESMO/16057&quot; target=&quot;_blank&quot;&gt;attempts&lt;/a&gt; to develop them.&lt;/p&gt;
&lt;p&gt;Her group had previously found that the CD24 protein  --  expressed on the cell surface, where it plays a role in cell adhesion and metastasis  --  was associated with development of colorectal cancer in a gene expression study.&lt;/p&gt;
&lt;p&gt;So, with two independent cohorts, they tested whether CD24 could be a good biomarker for colorectal cancer.&lt;/p&gt;
&lt;p&gt;The first cohort included 63 patients with colorectal cancer, 19 with adenoma, and 68 controls with a clean bill of health on colonoscopy. Of these 150 individuals, 143 were externally evaluated by a blinded investigator.&lt;/p&gt;
&lt;p&gt;CD24 expression was nearly six-fold higher among adenoma and colorectal cancer cases than among controls, a significant difference. Levels were similar between the cancer and adenoma groups.&lt;/p&gt;
&lt;p&gt;The second cohort included 73 subjects: 38 normal controls, 24 with colorectal adenoma, and 11 with colorectal cancer.&lt;/p&gt;
&lt;p&gt;The test could distinguish colorectal cancer cases from controls with &quot;relatively high&quot; sensitivity and specificity (92.3% and 83.8%, respectively), Kraus said.&lt;/p&gt;
&lt;p&gt;Its performance in detecting adenoma versus normal colonoscopy results was lower, 75.0% sensitivity and 89.2% specificity.&lt;/p&gt;
&lt;p&gt;Kraus said her group is now testing this CD24 approach in a larger sample and developing an enzyme-linked immunosorbent assay (ELISA) that could be more widely used.&lt;/p&gt;

      &lt;p&gt;For most patients in most categories, bariatric surgery increases life expectancy, according to a new mathematical model.&lt;/p&gt;
&lt;p&gt;Only when short-term mortality following bariatric surgery is expected to be high or the likelihood of success is low will the procedure fail to improve life expectancy, researchers reported in the January &lt;em&gt;Archives of Surgery&lt;/em&gt;.&lt;/p&gt;
&lt;p&gt;Computer modeling predicted that a hypothetical &quot;base case&quot; patient  --  a 42-year-old woman with a body mass index of 45  --  would gain 2.95 years of additional survival following bariatric surgery, according to Daniel P. Schauer, MD, of the University of Cincinnati, and colleagues.&lt;/p&gt;
&lt;p&gt;Surgery failed to be beneficial in the model only when 30-day mortality reached 9.5% or the likelihood that surgery would not add life-years was 2% or less, they found.&lt;/p&gt;
&lt;p&gt;Baseline 30-day mortality in the model was 0.2%, and the baseline efficacy of surgery in extending life expectancy was 53%.&lt;/p&gt;
&lt;p&gt;&quot;While not all patients are guaranteed a good outcome, our model indicates that gastric bypass increases life expectancy for most patient subgroups,&quot; they concluded.&lt;/p&gt;
&lt;p&gt;Their analysis was based on a Markov decision model using published data to estimate 30-day mortality following bariatric surgery and the efficacy of surgery in reducing long-term death rates.&lt;/p&gt;
&lt;p&gt;The latter had two components: reduction in excess mortality associated with obesity, and research data on long-term mortality following bariatric surgery.&lt;/p&gt;
&lt;p&gt;Excess mortality estimates came from National Health Interview Survey data on some 400,000 participants from 1991 to 1996 linked to the National Death Index. Inputs on surgery efficacy were derived from a 2007 study of nearly 8,000 patients who had undergone gastric bypass and the same number of medically treated or untreated obese controls.&lt;/p&gt;
&lt;p&gt;That study found that the procedure cut death rates by half during about seven years of follow-up. (See &lt;a href=&quot;http://www.medpagetoday.com/PrimaryCare/Obesity/6480&quot; mce_href=&quot;http://www.medpagetoday.com/PrimaryCare/Obesity/6480&quot; target=&quot;_blank&quot;&gt;Missing Link Found: Bariatric Surgery Reduces Mortality&lt;/a&gt;)&lt;/p&gt;
&lt;p&gt;Schauer and colleagues obtained rates of inhospital mortality following bariatric surgery from the 2005 National Inpatient Survey, then multiplied them by three to estimate 30-day mortality.&lt;/p&gt;
&lt;p&gt;The researchers explained that according to earlier research, inhospital death rates typically underestimate 30-day mortality by a factor of two to three.&lt;/p&gt;
&lt;p&gt;Their threefold correction factor represents &quot;a conservative estimate that biases the model against gastric bypass surgery,&quot; they wrote.&lt;/p&gt;
&lt;p&gt;Schauer and colleagues tested this correction factor and other aspects of the model in sensitivity analyses.&lt;/p&gt;
&lt;p&gt;The biggest gains in life expectancy occurred in younger women with relatively high BMI values, the model showed.&lt;/p&gt;
&lt;p&gt;The age effect was less important than BMI at the time of surgery. A 35-year-old woman with BMI of 45 would gain about 3.2 years of extra life, whereas at 55, a similarly obese woman would gain about 2.5 extra years.&lt;/p&gt;
&lt;p&gt;But a 35-year-old woman with BMI of 55 could expect to live five more years with surgery, the model indicated.&lt;/p&gt;
&lt;p&gt;Men in general derived less survival benefit from bariatric surgery, particularly with advancing age at the time of the procedure.&lt;/p&gt;
&lt;p&gt;At 35, the difference in life expectancy gained was roughly 10%, but by age 75 it had grown to about 50%.&lt;/p&gt;
&lt;p&gt;The sensitivity analyses found that relatively large changes in most parameters used in the model did not affect the overall results substantially.&lt;/p&gt;
&lt;p&gt;The effect of 30-day mortality on whether or not surgery was beneficial for long-term survival was related to BMI and gender.&lt;/p&gt;
&lt;p&gt;For women with a BMI of 40, 30-day mortality of more than 5% would mean surgery was not helpful, but short-term mortality had to exceed 15% for surgery not to be preferable for those with BMI of 55 or more. These thresholds were about 10% higher for men.&lt;/p&gt;
&lt;p&gt;The efficacy of surgery in reducing mortality was less important for older men, the analysis also showed. A 75-year-man with a BMI of 35 could expect only a very slight gain in life span  --  perhaps one or two months.&lt;/p&gt;
&lt;p&gt;&quot;Younger patients have lower surgical risk and more time over which to realize the benefits of surgery. For older patients, the gain is smaller, and for some, gastric bypass surgery will decrease life expectancy,&quot; Schauer and colleagues wrote.&lt;/p&gt;
&lt;p&gt;However, they identified several potentially serious limitations to the analysis.&lt;/p&gt;
&lt;p&gt;The study of long-term mortality following bariatric surgery was conducted at a single center and was not randomized. Additionally, long-term complications, such as need for repeat surgery, were not addressed in the model. Certain other risks that might be heightened after bariatric surgery were excluded as well, and quality of life was not modeled.&lt;/p&gt;
&lt;p&gt;&quot;The decision analysis presented here is a step forward in understanding optimal patient selection but also highlights some of the areas for which better data are needed,&quot; the researchers wrote.&lt;/p&gt;
