      &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="Heart Often Affected in Churg-Strauss (CME/CE)"
                     score="0.014"
                     href="http://www.medpagetoday.com/Rheumatology/GeneralRheumatology/tb/18353?impressionId=1265802907390"
                     
      &lt;p&gt;Cardiac involvement is common in patients with Churg-Strauss syndrome, even when their vasculitis is in clinical remission, a Dutch study found.&lt;/p&gt;
&lt;p&gt;Cardiac MRI detected abnormalities in 62% of patients with this rare, systemic disorder but in only 3% of matched controls (&lt;em&gt;P&lt;/em&gt;&amp;lt;0.001), according to Robert M. Dennert, MD, of Maastricht University in the Netherlands, and colleagues.&lt;/p&gt;
&lt;p&gt;Yet only 26% of the patients had clinical symptoms suggesting cardiac involvement, the researchers reported in February&apos;s &lt;em&gt;Arthritis &amp;amp; Rheumatism.&lt;/em&gt;&lt;/p&gt;
&lt;p&gt;Cardiac involvement is an important predictor of poor outcome in Churg-Strauss syndrome, with approximately half of the associated mortality being heart-related. Myocardial damage typically results from eosinophilic infiltration and granuloma formation.&lt;/p&gt;
&lt;p&gt;However, the cardiac manifestations are often subclinical. They remain undiagnosed, and the exact incidence is unclear.&lt;/p&gt;
&lt;p&gt;So Dennert and colleagues enrolled 32 patients with confirmed Churg-Strauss syndrome who were in complete clinical remission, performing detailed imaging assessments to determine the frequency and extent of heart involvement.&lt;/p&gt;
&lt;p&gt;About two-thirds were men. The mean age was 61 years, and disease duration was slightly over six years.&lt;/p&gt;
&lt;p&gt;A total of 41% had antineutrophil cytoplasmic antibodies (ANCA), and most were on maintenance steroids or immunosuppressants.&lt;/p&gt;
&lt;p&gt;On EKG, major abnormalities (atrial fibrillation and conduction disturbances) were detected in only 13% of patients. Minor abnormalities such as T wave abnormalities were seen in 50% of patients and in one control subject.&lt;/p&gt;
&lt;p&gt;Echocardiography identified abnormalities in 50% of patients and in 3% of controls (&lt;em&gt;P&lt;/em&gt;&amp;lt;0.001). These included wall motion and valvular abnormalities, pericardial effusion, and pulmonary hypertension.&lt;/p&gt;
&lt;p&gt;In the 62% of patients whose MRIs revealed abnormalities, findings included fibrosis, inflammation, wall motion and valvular abnormalities, pericardial effusion, and obliterated right ventricle.&lt;/p&gt;
&lt;p&gt;Previous reports had suggested that ANCA positivity in Churg-Strauss syndrome was more often associated with renal disease and peripheral neuropathy, while ANCA negativity was associated with fever and heart involvement.&lt;/p&gt;
&lt;p&gt;In this cohort, 74% of ANCA-negative patients had cardiac involvement, and in 64%, these were wall motion disturbances.&lt;/p&gt;
&lt;p&gt;In comparison, only 23% of ANCA-positive patients had heart involvement.&lt;/p&gt;
&lt;p&gt;Defects were identified with echocardiography or MRI in 88% of patients who had clinical symptoms, and in all who had major EKG abnormalities.&lt;/p&gt;
&lt;p&gt;But in the absence of symptoms and even with a normal EKG, abnormalities could still be detected on echocardiography or MRI in almost 40% of patients, according to the investigators.&lt;/p&gt;
&lt;p&gt;&quot;We therefore recommend that the evaluation for cardiac involvement in patients with [Churg-Strauss syndrome] should include not only detailed history of cardiac symptoms and EKG, but also imaging with echocardiography or cardiac MRI,&quot; they stated.&lt;/p&gt;
&lt;p&gt;The high prevalence of heart abnormalities could not be attributed to concomitant heart disease such as coronary artery disease or hypertension, because the prevalence of these diseases among patients was comparable to that in controls.&lt;/p&gt;
&lt;p&gt;Churg-Strauss syndrome typically develops in three phases, beginning with asthma, followed by peripheral and tissue eosinophilia accompanied by pulmonary infiltrates, and finally the systemic small-vessel vasculitis.&lt;/p&gt;
&lt;p&gt;During this late phase the vasculitic lesions in the coronary vessels and myocardium can lead to myocardial infarction, heart failure, and cardiac tamponade.&lt;/p&gt;
&lt;p&gt;Studies have shown that long-term treatment with immunosuppressive drugs can improve survival and resolve the cardiac abnormalities, so early diagnosis is needed.&lt;/p&gt;
&lt;p&gt;The authors acknowledged that their study was cross-sectional, and that a longitudinal study could have provided more detailed data.&lt;/p&gt;
&lt;p&gt;Nonetheless, the study revealed a high incidence of cardiac involvement, which was often unrecognized, and they concluded that a multidisciplinary approach to management therefore should include a cardiologist.&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;

      &lt;p&gt;Middle-aged patients with early knee osteoarthritis can benefit from either a self-managment program or strength training, but a combination of the two did not provide additional gains, a study found.&lt;/p&gt;
&lt;p&gt;During a two-year trial, roughly two-thirds of participants randomized to one of three groups achieved clinically meaningful improvements in functioning, defined as a 26% change from baseline, according to a new report in the Jan. 15 &lt;em&gt;Arthritis Care &amp;amp; Research&lt;/em&gt;.&lt;/p&gt;
&lt;p&gt;Patients also achieved clinically meaningful improvements in pain -- defined as a 40% change from baseline -- regardless of treatment group, wrote Patrick E. McKnight, PhD, of George Mason University in Fairfax, Va., and colleagues.&lt;/p&gt;
&lt;p&gt;The functional improvements were 70% for patients in the strength training group, 64% for those in the self-management group, and a 66% improvement in the combined treatment group. For pain, the breakdown was as follows: &lt;ul&gt; &lt;li&gt;Strength training, 65%&lt;/li&gt; &lt;li&gt;Self-management, 56%&lt;/li&gt; &lt;li&gt;Combined treatment, 65%&lt;/li&gt; &lt;/ul&gt;&lt;/p&gt;
&lt;p&gt;McKnight and colleagues wrote that studies in older patients have reported positive changes for both strength training and self-management.&lt;/p&gt;
&lt;p&gt;To see if these modalities also could benefit younger patients with milder disease, and whether combining the two would lead to additional benefits, the investigators recruited 273 subjects ages 35 to 64 years.&lt;/p&gt;
&lt;p&gt;Participants all had pain on most days in at least one knee, had symptoms for less than five years, had radiographic evidence of osteoarthritis, and had self-reported disability.&lt;/p&gt;
&lt;p&gt;The strength training program consisted of two phases, the first being nine months focused on stretching and balance, range of motion and flexibility, and isotonic muscle strengthening in three sessions each week.&lt;/p&gt;
&lt;p&gt;Phase two involved the development of self-directed long-term exercising habits, following the guidance and advice of trainers.&lt;/p&gt;
&lt;p&gt;The self-management program also included two phases. During the first nine-month phase, participants attended 12 weekly 90-minute classroom sessions addressing coping and self-efficacy skills, promoting active adaptive strategies and increasing perception of control for physical function and pain management.&lt;/p&gt;
&lt;p&gt;Phase two consisted of telephone calls from instructors and problem-solving discussions.&lt;/p&gt;
&lt;p&gt;The combined treatment group concurrently participated in both strength training and self-management programs, adjusted to maintain equivalent contact time with the other two groups.&lt;/p&gt;
&lt;p&gt;Overall compliance was modest, with 55.8% of those in the strength training group completing the study, along with 69.1% and 59.6% of the self-management and combined groups, respectively.&lt;/p&gt;
&lt;p&gt;Objective measures of physical functioning consisted of five physical performance tests measured at baseline and at months nine and 24. Pain and disability were self-reported.&lt;/p&gt;
&lt;p&gt;All of these outcomes showed significant changes over time in all three treatment groups, with effect sizes computed using the standard Cohen&apos;s d units: &lt;ul&gt; &lt;li&gt;Leg press, d=0.85&lt;/li&gt; &lt;li&gt;Range of motion, d=1.00&lt;/li&gt; &lt;li&gt;Work capacity, d=0.60&lt;/li&gt; &lt;li&gt;Balance, d=0.59&lt;/li&gt; &lt;li&gt;Stair climbing, d=0.59&lt;/li&gt; &lt;li&gt;Pain, d= &amp;#8722;0.51&lt;/li&gt; &lt;li&gt;Disability, d= &amp;#8722;0.55&lt;/li&gt; &lt;/ul&gt;&lt;/p&gt;
&lt;p&gt;Both men and women improved, although benefits were greater among men, who gained more large muscle mass strength. Study-related adverse effects included accident, injury, or increased pain with strength training.&lt;/p&gt;
&lt;p&gt;Within-group and between-group effect sizes were also computed. All within-group effect sizes differed significantly from zero, with the exception of the pain outcome in the strength training group, but none of the between-group effects were significant.&lt;/p&gt;
&lt;p&gt;&quot;The logic behind the combined treatment was that the different factors addressed in physical and psychological treatments might produce an additive effect if administered together. These results suggest otherwise,&quot; the investigators conceded.&lt;/p&gt;
&lt;p&gt;As to why there were no differences between the three treatment arms, the length of the study and the relative youth of the participants may have contributed.&lt;/p&gt;
&lt;p&gt;The sample was younger than are included in typical osteoarthritis studies and were higher functioning at baseline, which could mean that there was less opportunity to produce a significant effect, the investigators suggested.&lt;/p&gt;
&lt;p&gt;Also, the increased burden of the combined treatment may have diluted the effects of the two programs.&lt;/p&gt;
&lt;p&gt;Despite the fact that combined treatment in this study had negligible benefits beyond that seen with strength training and self-management, other long-term outcomes such as physical activity level might show a greater response. This remains speculative, but deserves further study, according to the investigators.&lt;/p&gt;
&lt;p&gt;Limitations of the study include the fact that the researchers did not assess effects of the treatment on articular cartilage or inflammation, and they did not include a no-treatment arm.&lt;/p&gt;
&lt;p&gt;Also, there may have been differences in self-medication practices between the groups.&lt;/p&gt;
&lt;p&gt;Nonetheless, the study findings suggest that the two nonpharmacologic approaches can produce gains in middle-age patients with osteoarthritis, and both can be recommended.&lt;/p&gt;

                     title="Benefits of Cutting Down on Salt Quantified (CME/CE)"
                     score="-0.002"
                     href="http://www.medpagetoday.com/Cardiology/Prevention/tb/18075?impressionId=1265802907390"
                     
      &lt;p&gt;Cutting daily salt intake by 3 grams a day  --  about 30% of the current average  --  could prevent 32,000 strokes and 54,000 myocardial infarctions a year, if a computer model developed by researchers at the University of California, San Francisco accurately depicts the clinical impact of salt reduction.&lt;/p&gt;
&lt;p&gt;The results of the analysis, which used a computer simulation of heart disease in U.S. adults ages 35 to 84, also suggest that even a 1 gram per day reduction in salt over the next decade would be a more cost-effective strategy for treating hypertension than use of even the cheapest antihypertensive, wrote Kirsten Bibbins-Domingo, MD, PhD, and colleagues in a paper published online by the &lt;em&gt;New England Journal of Medicine.&lt;/em&gt;&lt;/p&gt;
&lt;p&gt;Lee Goldman, MD, MPH, of Columbia University, who co-authored the paper, told &lt;em&gt;MedPage Today&lt;/em&gt; that their study builds on what has long been known about the adverse health effects of salt on a society that believes it to be the spice of life.&lt;/p&gt;
&lt;p&gt;For example, Goldman said that most people seeking a healthy choice will check food labels and restaurant menus for calorie counts and trans fats, but will not pay attention to salt.&lt;/p&gt;
&lt;p&gt;This is not the first time a call for salt reduction has been issued. As recently as last November, a meta-analysis published in &lt;em&gt;BMJ &lt;/em&gt;suggested that cutting salt intake in half  --  a reduction of about 5 grams a day or roughly a teaspoonful  --  would lower the stroke rate by 23% and reduce overall cardiovascular disease by as much as 17%.&lt;/p&gt;
&lt;p&gt;Americans, like those in many Western countries, take in an average of about 10 g of salt a day; whereas the World Health Organization recommends only 5 g per day, and the U.S. Department of Agriculture recommends daily intake be limited to 5.8 g.&lt;/p&gt;
&lt;p&gt;Bibbins-Domingo and colleagues reported that a 3 gram per day reduction in dietary salt would &quot;save 194,00 to 392,00 quality-adjusted life-years and $10 billion to $24 billion in healthcare costs annually.&quot;&lt;/p&gt;
&lt;p&gt;In an editorial that accompanied the study, Lawrence J. Appel, MD, MPH, and Cheryl A.M. Anderson, PhD, MPH, of Johns Hopkins University, wrote that &quot;the evidence supporting the call to reduce salt intake as a means of preventing cardiovascular disease is compelling.&quot;&lt;/p&gt;
&lt;p&gt;They concluded with this admonition: &quot;As we deliberate healthcare reform, let us not neglect this inexpensive, yet highly effective public health intervention for the prevention of disease.&quot;&lt;/p&gt;
&lt;p&gt;It should be noted that Appel was also first author on a position paper from the American Society of Hypertension that also called for salt reduction as public policy.&lt;/p&gt;
&lt;p&gt;Franz H. Messerli, MD, director of the hypertension program at St. Luke&apos;s-Roosevelt Hospital and a colleague of Goldman&apos;s, said the computer model used in the study was impressive but probably underestimates the benefit of reducing dietary salt &quot;because salt reduction has been shown to have a direct (blood pressure independent) effect on the heart, the brain, the kidneys, and also reduces stomach cancer and osteoporosis  --  factors that were not considered in this analysis.&quot;&lt;/p&gt;
&lt;p&gt;But Messerli found it difficult to lead the victory parade, noting &quot;this is a modeling study and statements such as &apos;A modest reduction of 1 gm per day would be more cost-effective than using medication to lower blood pressure in all persons with hypertension&apos; are to be taken with a good grain of salt.&quot;&lt;/p&gt;
&lt;p&gt;Messerli&apos;s measured response was not echoed by his colleagues in the hypertension world.&lt;/p&gt;
&lt;p&gt;For example, Henry Black, MD, president of the American Society of Hypertension, and director of hypertension research at the New York University School of Medicine said that, although the paper extended the findings of many other studies, it is &quot;more comprehensive and is especially useful by comparing the benefits of [sodium] and [salt] reduction to those of other widely accepted public health approaches that the public and governmental bodies have embraced, including drug treatment.&quot;&lt;/p&gt;
&lt;p&gt;Clyde Yancy, MD, president of the American Heart Association, said that while the study was a computer modeling analysis that may be as good as it gets because &quot;it would be impossible to do a randomized trial in large numbers of high versus low sodium consumption, and the use of modeling with reasonable assumptions represents a solid if not ideal alternative.&quot;&lt;/p&gt;
&lt;p&gt;Moreover, Yancy argued that &quot;the costs and effort involved in setting and/or changing policy&quot; require strong imperatives, and he thought the data reported today &quot;provide that imperative.&quot;&lt;/p&gt;
&lt;p&gt;Three grams of salt comes to about a teaspoonful, but Goldman said it was foolish to think of sodium reduction in terms of such measurements because so much sodium comes from processed foods and from restaurant food. Achieving the needed reduction requires a concerted national effort.&lt;/p&gt;
&lt;p&gt;Bibbins-Domingo noted that their study was limited &quot;by any uncertainty concerning the data entered into the model.&quot;&lt;/p&gt;
&lt;p&gt;Also they noted that they did not &quot;account fully for the possible effects of salt reduction that are unrelated to control of blood pressure  --  for example, potential improvements in outcomes for the increasing numbers of patients with heart failure or prevention of other serious conditions, such as end-stage renal disease.&quot;&lt;/p&gt;
