      &lt;p&gt;SAN ANTONIO  --  A personalized, online self-management program helped patients with pain syndromes improve coping skills and reduce stress and depression in two studies reported here.&lt;/p&gt;
&lt;p&gt;Patients randomized to the self-management program demonstrated significant improvement in multiple social, emotional, and behavioral outcomes after six months (&lt;em&gt;P&lt;/em&gt;&amp;lt;0.05 to &lt;em&gt;P&lt;/em&gt;&amp;lt;0.01). Improvement in some parameters occurred within one month. A control group that was not exposed to the program showed no significant improvement.&lt;/p&gt;
&lt;p&gt;&quot;Our goal is to help people communicate better with providers, understand better how they can use social support, understand the comorbid conditions, like anxiety and depression, and develop cognitive skills to help get them through their pain episodes,&quot; said Emil Chiauzzi, PhD, of Inflexxion, the Newton, Mass. company that developed the program.&lt;/p&gt;
&lt;p&gt;Although the studies involved patients with migraine or low-back pain, programs are being developed for other types of pain condition, including several forms of neuropathic pain.&lt;/p&gt;
&lt;p&gt;The online program, demonstrated at &lt;a href=&quot;http://www.painACTION.com&quot; mce_href=&quot;http://www.painACTION.com&quot; target=&quot;_blank&quot;&gt;www.painACTION.com&lt;/a&gt;, employs patient-specific information to generate individualized self-management strategies.&lt;/p&gt;
&lt;p&gt;Patient responses to assessments are analyzed by a &quot;recommendation engine,&quot; which produces content recommendations designed to address each patient&apos;s informational and self-management needs.&lt;/p&gt;
&lt;p&gt;Elements on the Web site include multimedia education units, a pain inventory, interactive tools that provide information based on patient-provider communication, and medication risk management.&lt;/p&gt;
&lt;p&gt;&quot;The content on the Web site is focused on teaching people practical skills to manage the behavioral side of pain,&quot; Jonas Bromberg, PsyD, also of Inflexxion, said in an interview.&lt;/p&gt;
&lt;p&gt;Bromberg presented results of a randomized study involving 210 patients, all of whom met International Headache Society diagnostic criteria for migraine, with or without aura.&lt;/p&gt;
&lt;p&gt;Patients assigned to the online program completed at least eight 30-minute session during the first month of the study and at least five more 30-minute sessions during the five-month follow-up period. Patients in the control group continued to receive usual care without exposure to the Web site.&lt;/p&gt;
&lt;p&gt;Participants assigned to the online program had a minimum set of requirements for each session, which were provided at log-in. Follow-up assessments occurred at one, three, and six months.&lt;/p&gt;
&lt;p&gt;The two groups were balanced with respect to sex and headache frequency and severity, the researchers said.&lt;/p&gt;
&lt;p&gt;Bromberg reported that patients assigned to the self-management program demonstrated significant improvement in: &lt;ul&gt; &lt;li&gt;Headache self-efficacy (&lt;em&gt;P&lt;/em&gt;&amp;lt;0.01 compared with baseline)&lt;/li&gt; &lt;li&gt;Use of relaxation (&lt;em&gt;P&lt;/em&gt;&amp;lt;0.05 to &lt;em&gt;P&lt;/em&gt;&amp;lt;0.01)&lt;/li&gt; &lt;li&gt;Use of social support (&lt;em&gt;P&lt;/em&gt;&amp;lt;0.01)&lt;/li&gt; &lt;li&gt;Pain catastrophizing (&lt;em&gt;P&lt;/em&gt;&amp;lt;0.01)&lt;/li&gt; &lt;li&gt;Depression (&lt;em&gt;P&lt;/em&gt;&amp;lt;0.05 to &lt;em&gt;P&lt;/em&gt;&amp;lt;0.01)&lt;/li&gt; &lt;li&gt;Stress (&lt;em&gt;P&lt;/em&gt;&amp;lt;0.01)&lt;/li&gt; &lt;/ul&gt;&lt;/p&gt;
&lt;p&gt;Chiauzzi presented results from a randomized study of 209 patients with low-back pain. The design was similar to that of the migraine study, except results were analyzed for between-group differences.&lt;/p&gt;
&lt;p&gt;The results showed significant improvement in the study group versus control group with respect to: &lt;ul&gt; &lt;li&gt;Stress (&lt;em&gt;P&lt;/em&gt;&amp;lt;0.01)&lt;/li&gt; &lt;li&gt;Coping (&lt;em&gt;P&lt;/em&gt;&amp;lt;0.01)&lt;/li&gt; &lt;li&gt;Social supports (&lt;em&gt;P&lt;/em&gt;&amp;lt;0.05)&lt;/li&gt; &lt;/ul&gt;&lt;/p&gt;
&lt;p&gt;The data showed significant effects of both treatment (&lt;em&gt;P&lt;/em&gt;&amp;lt;0.01) and time (&lt;em&gt;P&lt;/em&gt;&amp;lt;0.01) favoring the Web site versus control. Chiauzzi said patients assigned to the Web site had greater mean improvement at posttest, three months, and six months.&lt;/p&gt;
&lt;p&gt;Qualitative analysis suggested that Web site participants had clinically meaningful improvement in depression, anxiety, and stress.&lt;/p&gt;
&lt;p&gt;Additionally, patients in the self-management program reported a 12.3% decrease in pain from baseline, versus 7% in the control group.&lt;/p&gt;
&lt;p&gt;Access to the Web site did not improve physical functioning.&lt;/p&gt;

                     title="Low Vitamin D Linked to Hip OA (CME/CE)"
                     score="0.013"
                     href="http://www.medpagetoday.com/Rheumatology/Arthritis/tb/18379?impressionId=1265786055198"
                     
      &lt;p&gt;Elderly men with low serum levels of vitamin D are at increased risk for developing hip osteoarthritis, a prospective cohort study found.&lt;/p&gt;
&lt;p&gt;Men whose levels of 25-hydroxyvitamin (OH)D were between 15.1 to 30 ng/mL had twice the likelihood of prevalent radiographic hip osteoarthritis than those whose levels were normal (OR 2.19, 95% CI 1.21 to 3.97), according to R. Krishna Chaganti, MD, of the University of California at San Francisco, and colleagues.&lt;/p&gt;
&lt;p&gt;Conversely, after adjusting for age, season at blood draw, and clinic site, higher vitamin D levels were associated with a lower prevalence of hip osteoarthritis (OR 1.39 per 1 SD decrease in 25(OH)D level, 95% CI 1.11 to 1.74), the researchers reported in the February issue of &lt;em&gt;Arthritis &amp;amp; Rheumatism&lt;/em&gt;.&lt;/p&gt;
&lt;p&gt;Because the role vitamin D may play in the pathogenesis and progression of osteoarthritis is unclear, Chaganti and colleagues analyzed data from the Osteoporotic Fractures in Men Study, which enrolled a large cohort of elderly men between 2000 and 2002 from six centers across the U.S.&lt;/p&gt;
&lt;p&gt;A total of 1,104 men whose mean age was 77.2 years had baseline measurements of serum vitamin D, and about 4.5 years later pelvic radiographs were obtained.&lt;/p&gt;
&lt;p&gt;Radiographs were scored to reflect joint space narrowing, osteophyte formation, cysts, subchondral sclerosis, and femoral head deformity.&lt;/p&gt;
&lt;p&gt;Vitamin D levels were categorized as deficiency (&amp;#8804;15 ng/mL), insufficiency (15.1 to 30 ng/mL), and sufficiency (&amp;gt;30 ng/mL).&lt;/p&gt;
&lt;p&gt;Mean vitamin D level was 23.38 ng/mL in men who had radiographic hip osteoarthritis, compared with 26.04 ng/mL in men without radiographic abnormalities (&lt;em&gt;P&lt;/em&gt;=0.0002).&lt;/p&gt;
&lt;p&gt;Men with hip osteoarthritis had a higher prevalence of both vitamin D insufficiency (77% versus 65%, &lt;em&gt;P&lt;/em&gt;=0.002) and deficiency (10.2% versus 7.5%, &lt;em&gt;P&lt;/em&gt;=0.012).&lt;/p&gt;
&lt;p&gt;Moreover, they had slower six-meter walking speed (&lt;em&gt;P&lt;/em&gt;&amp;lt;0.0001) and reported more hip pain (&lt;em&gt;P&lt;/em&gt;=0.0001).&lt;/p&gt;
&lt;p&gt;Men who were vitamin D deficient also tended to have an increased likelihood of hip osteoarthritis (OR 1.99, 95% CI 0.83 to 4.74), but after adjustment in multivariate models, statistical significance was lost with this level of the vitamin.&lt;/p&gt;
&lt;p&gt;&quot;The association of low 25(OH)D levels with prevalent radiographic hip [osteoarthritis] underscores the potentially important role of vitamin D in the pathogenesis of [osteoarthritis]. Vitamin D metabolites have been found to be associated with the regulation of the Wnt pathway, products of which play important roles in the development and maintenance of bone and cartilage,&quot; the investigators explained.&lt;/p&gt;
&lt;p&gt;Furthermore, in vitro studies have suggested that serum levels of 25-hydroxyvitamin D&lt;sub&gt;3&lt;/sub&gt; can affect the ratio of RANKL to osteoprotegerin and thereby influence bone deterioration and repair.&lt;/p&gt;
&lt;p&gt;Previous investigations have yielded conflicting results. One study found that low levels of vitamin D were not associated with worsening of knee osteoarthritis, as reflected in loss of articular cartilage on MRI.&lt;/p&gt;
&lt;p&gt;Another study, however, linked knee osteoarthritis with low vitamin D levels, particularly in patients who also had decreased bone mineral density in the lumbar spine.&lt;/p&gt;
&lt;p&gt;&quot;Vitamin D influences the mineralization of bone matrix, and low serum levels of vitamin D may result in poorly mineralized bone that might alter forces across the joint and reduce joint deterioration,&quot; the authors suggested.&lt;/p&gt;
&lt;p&gt;On the other hand, low levels may interfere with chondrocyte metabolism and thereby increase degeneration.&lt;/p&gt;
&lt;p&gt;Further studies will be needed to more fully clarify the effects of the vitamin on the development and progression of osteoarthritis, the investigators cautioned.&lt;/p&gt;
&lt;p&gt;Strengths of the study include the large cohort of participants, careful classification of radiographic osteoarthritis, and reliance on the gold standard of vitamin D measurement, the 25(OH)D level.&lt;/p&gt;
&lt;p&gt;Limitations include the cross-sectional design, precluding the inference of causality, and the gap in time between measurement of serum vitamin D and radiography.&lt;/p&gt;
&lt;p&gt;The authors concluded that therapeutic interventions to increase vitamin D serum levels in the elderly &quot;are warranted,&quot; with the goal of improving skeletal health in this vulnerable age group.&lt;/p&gt;

      &lt;p&gt;SAN ANTONIO  --  A humanized monoclonal antibody against nerve growth factor provided relief in three chronic pain syndromes, according to a summary of small studies reported as an abstract here.&lt;/p&gt;
&lt;p&gt;Treatment with tanezumab led to statistically or clinically significant reductions in pain for patients with osteoarthritis, chronic lower back pain, and interstitial cystitis. The most common adverse events were transient abnormal peripheral sensations, which generally occurred only after the first infusion.&lt;/p&gt;
&lt;p&gt;&quot;Patients with these three different pain syndromes all had significant improvement when treated with tanezumab,&quot; Leslie Tive, PhD, of Pfizer, said in an interview at the American Academy of Pain Medicine meeting. &quot;The pain relief was sustained over time, and patient acceptance was good.&quot;&lt;/p&gt;
&lt;p&gt;&quot;Nerve growth factor is increased in many types of chronic pain and therefore represents an attractive target for therapy,&quot; she added. &quot;Tanezumab is being evaluated in some of these other conditions in ongoing studies.&quot;&lt;/p&gt;
&lt;p&gt;A small phase I study showed that the humanized monoclonal antibody resulted in significant pain improvement in patients with osteoarthritis (&lt;em&gt;Arthritis Rheum&lt;/em&gt; 2005; 52: S461). Tive presented data from a phase II trial involving 400 patients with osteoarthritis of the knee. They were randomized to placebo or to one of five tanezumab doses, administered on day one and day 56.&lt;/p&gt;
&lt;p&gt;All five doses of tanezumab resulted in significant reductions (&lt;em&gt;P&lt;/em&gt;&amp;lt;0.05) versus placebo after one week and were sustained through 16 weeks. As assessed by a visual analog scale, the mean change in pain on walking from baseline to week 16 ranged from 30 to 45 points (&lt;em&gt;P&lt;/em&gt;&amp;lt;0.0001), a two- to threefold difference compared with placebo.&lt;/p&gt;
&lt;p&gt;The trial in chronic low back pain involved 217 adults with Quebec Task Force on Spinal Disorders category 1 or 2 pain for at least three months. The primary location of the pain was between the 12th thoracic vertebra and the lower gluteal folds.&lt;/p&gt;
&lt;p&gt;Eligibility criteria included a score of at least 4 on an 11-point pain scale on at least four occasions in the five days before randomization, as indicated by entries in an electronic pain diary.&lt;/p&gt;
&lt;p&gt;Patients were randomized 2:2:1 to a single infusion of tanezumab, to oral naproxen, or to placebo. The primary endpoint was the change in mean Lower Back Pain Index score from baseline to six weeks, averaged over the last seven days.&lt;/p&gt;
&lt;p&gt;Beginning at week one and continuing through week six, patients who were randomized to either dose of tanezumab had significantly greater improvement in pain than those who took the placebo (&lt;em&gt;P&lt;/em&gt;&amp;lt;0.05 to &lt;em&gt;P&lt;/em&gt;&amp;lt;0.001), and compared with the naproxen group beginning at week two (&lt;em&gt;P&lt;/em&gt;&amp;lt;0.05 to &lt;em&gt;P&lt;/em&gt;&amp;lt;0.01).&lt;/p&gt;
&lt;p&gt;The interstitial cystitis study included 64 men and women who had a score &amp;#8805;13 on Pelvic Pain Symptom/Frequency questionnaire, &amp;#8805;7 score on the O&apos;Leary-Sant Interstitial Cystitis index, and micturition frequency &amp;#8805;8 times a day, as recorded in an electronic diary for at least five consecutive days prior to randomization.&lt;/p&gt;
&lt;p&gt;Patients were randomized to intravenous tanezumab or matching placebo. The primary efficacy endpoint was change from baseline to six weeks in the 11-point pain scale. A difference of at least one point from placebo was considered clinically significant. Statistical significance was not evaluated.&lt;/p&gt;
&lt;p&gt;The mean difference between tanezumab and placebo was -0.7 at week two, increasing to -1.1 at week four and -1.4 at week six. The advantage versus placebo was maintained at week 10 (-0.9) and week 16 (-0.5).&lt;/p&gt;
&lt;p&gt;Adverse events were evaluated for all patients combined in the three studies. Adverse events were reported by 66.3% of tanezumab patients, 61.4% of naproxen patients, and 59.3% of placebo patients. Serious and severe adverse events occurred in 1.6% to 3.4% of patients and 4.8% to 5.7%, respectively.&lt;/p&gt;
&lt;p&gt;Tive said 14.4% of tanezumab patients reported abnormal peripheral sensations, the most common being paresthesia (7.1%), hyperesthesia (4.1%), and hypoesthesia (3.9%).&lt;/p&gt;

                     score="0.004"
                     href="http://www.medpagetoday.com/Geriatrics/GeneralGeriatrics/tb/18173?impressionId=1265786055198"
                     
      &lt;p&gt;Raising seniors&apos; copayments for ambulatory care to offset increasing healthcare costs may backfire on insurers, researchers asserted.&lt;/p&gt;
&lt;p&gt;Seniors enrolled in Medicare plans that increased copayments had significantly fewer outpatient visits but spent more time in the hospital than patients in plans that left copayments untouched, according to Amal Trivedi, MD, MPH, of Brown University in Providence, R.I., and colleagues.&lt;/p&gt;
&lt;p&gt;Assuming an average reimbursement of $60 for an outpatient visit, seven annual visits per enrollee, and an average copay increase of $8.50 per visit, a plan should save $7,150 for every 100 enrollees, they noted in the Jan. 28 &lt;em&gt;New England Journal of Medicine&lt;/em&gt;.&lt;/p&gt;
&lt;p&gt;But, assuming an average cost of $11,065 per hospitalization of a person 65 to 84, the researchers estimated that the costs for inpatient care would actually increase by $24,000 for every 100 enrollees in the year after copays are increased.&lt;/p&gt;
&lt;p&gt;Even using more conservative criteria, the increased costs for inpatient care would nearly double any savings from increasing copays, they argued.&lt;/p&gt;
&lt;p&gt;&quot;Cost-sharing has generally been thought to reduce total healthcare spending without harming health for the average person,&quot; the researchers wrote, but these results suggest increasing copays in Medicare beneficiaries &quot;may be a particularly ill-advised cost-containment strategy.&quot;&lt;/p&gt;
&lt;p&gt;Increasing copayments may be particularly harmful to older patients, they said, because they have lower incomes and are more likely to have poor health and greater out-of-pocket healthcare expenses than younger patients.&lt;/p&gt;
&lt;p&gt;To explore the issue in a Medicare population, Trivedi and colleagues compared the use of outpatient and inpatient care between enrollees in 18 plans that increased copays for ambulatory care and 18 that did not. The study included 899,060 patients.&lt;/p&gt;
&lt;p&gt;According to data from the Medicare Healthcare Effectiveness Data and Information Set from the Centers for Medicare and Medicaid Services, mean copays increased during the study period for both primary care ($7.38 to $14.38) and specialty care ($12.66 to $22.05) in the case plans.&lt;/p&gt;
&lt;p&gt;Mean copays remained stable at $8.33 and $11.38 for primary and specialty care, respectively, in the control plans.&lt;/p&gt;
&lt;p&gt;In both groups, there were increases in the number of ambulatory visits over time, but the increase was smaller in the plans that raised copays.&lt;/p&gt;
&lt;p&gt;There was also a rise in the number of hospitalizations, the proportion of patients who were hospitalized, and the length of time spent in the hospital in both groups, but there were larger increases in the plans that increased copays.&lt;/p&gt;
&lt;p&gt;Compared with the control plans, in the year after the increase in copays, case plans had: &lt;ul&gt; &lt;li&gt;19.8 fewer annual outpatient visits per 100 enrollees (95% CI 16.6 to 23.1)&lt;/li&gt; &lt;li&gt;2.2 additional annual hospital admissions per 100 enrollees (95% CI 1.8 to 2.6)&lt;/li&gt; &lt;li&gt;13.4 more annual inpatient days per 100 enrollees (95% CI 10.2 to 16.6)&lt;/li&gt; &lt;li&gt;A 0.7% increase in the proportion of enrollees who were hospitalized (95% CI 0.51% to 0.95%)&lt;/li&gt; &lt;/ul&gt;&lt;/p&gt;
&lt;p&gt;The findings were amplified among enrollees living in areas of lower income and education, black patients, and those who had hypertension, diabetes, or a history of myocardial infarction.&lt;/p&gt;
&lt;p&gt;Trivedi and colleagues noted some limitations of the analysis: it was not randomized, and unmeasured differences could have influenced the results.&lt;/p&gt;
&lt;p&gt;Also, the case and control plans could not be matched in a geographic area smaller than census region because of the small number of Medicare plans, and data were lacking on diagnoses, procedures, and costs associated with hospital admissions and outpatient visits.&lt;/p&gt;

                     score="0.003"
                     href="http://www.medpagetoday.com/HematologyOncology/ColonCancer/tb/18164?impressionId=1265786055198"
                     
      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;
