      &lt;p&gt;Public health experts say they&apos;re concerned about the low number of U.S. adults who receive recommended vaccinations  --  and in particular about seniors who aren&apos;t immunized against pneumonia.&lt;/p&gt;
&lt;p&gt;As of 2008, one-third of people 65 and older had not received the pneumococcal vaccine, according to a report issued by the Trust for America&apos;s Health (TFAH), the Infectious Diseases Society of America (IDSA), and the Robert Wood Johnson Foundation.&lt;/p&gt;
&lt;p&gt;In 36 states, 30% or more of their older residents had not received the vaccine.&lt;/p&gt;
&lt;p&gt;The worst coverage was in the District of Columbia, where 45.6% of seniors had not been vaccinated. Even in the best performing state, Oregon, more than a quarter (26.8%) of older people had not received the one-time shot.&lt;/p&gt;
&lt;p&gt;Among all adults, the investigators also found extremely low rates of immunization against tetanus, diphtheria, and pertussis (2.1%), shingles (&amp;lt;2%), human papillomavirus (10%), and seasonal influenza (36.1%).&lt;/p&gt;
&lt;p&gt;&quot;The vaccination efforts around the 2009 H1N1 outbreak actually showed how well our public health system can react to vaccinate millions of people in a very short amount of time,&quot; L.J. Tan, PhD, director of medicine and public health for the American Medical Association, told reporters in a conference call.&lt;/p&gt;
&lt;p&gt;&quot;But I think our response also clearly demonstrated that we do have a lack of a strategy and a system for vaccinating adults.&quot;&lt;/p&gt;
&lt;p&gt;Added Jeffrey Levi, PhD, executive director of TFAH, &quot;We need a national strategy to make vaccines a regular part of medical care and to educate Americans about the effectiveness and safety of vaccines.&quot;&lt;/p&gt;
&lt;p&gt;Doing so could avoid 40,000 to 50,000 deaths from vaccine-preventable illnesses and save about $10 billion in healthcare costs each year, he said.&lt;/p&gt;
&lt;p&gt;But, according to William Schaffner, MD, chair of IDSA&apos;s immunization working group and a co-author of the report, there are many obstacles to adult vaccination efforts.&lt;/p&gt;
&lt;p&gt;First, unlike children in school, adults lack widespread institutional access to immunizations nor is there a way to require most adults to undergo vaccination.&lt;/p&gt;
&lt;p&gt;In addition, there are limited interactions with the healthcare system because, also unlike in children, care in adults generally revolves around acute care and not well care visits.&lt;/p&gt;
&lt;p&gt;Insurance coverage also plays a major role in low vaccination rates among adults, and not just in the uninsured or underinsured.&lt;/p&gt;
&lt;p&gt;Most insurance plans do not cover routine vaccination, Schaffner said, a situation that would change under pending healthcare reform legislation in Congress. That would require insurers to pay for all vaccinations recommended by the CDC&apos;s Advisory Committee on Immunization Practices.&lt;/p&gt;
&lt;p&gt;Schaffner also cited what he called misunderstandings and misinformation regarding the safety and effectiveness of vaccines, and the limited support for research, development, and production of vaccines as reasons for low immunization rates among adults.&lt;/p&gt;
&lt;p&gt;&quot;It&apos;s a shame that we aren&apos;t focusing enough resources on the science to prevent disease and we don&apos;t have a system where we can better protect people by getting them all of the vaccines that are currently available,&quot; he said.&lt;/p&gt;
&lt;p&gt;Tan outlined several recommendations the report makes to increase adult vaccination rates, starting with the creation of a program to provide vaccine coverage to uninsured individuals.&lt;/p&gt;
&lt;p&gt;Also, he said, the CDC and local and state health departments should be given more funding to conduct public education campaigns to increase awareness about the importance of vaccination.&lt;/p&gt;
&lt;p&gt;For their part, physicians should adopt practices to enable them to offer their adult patients vaccines at appropriate visits, like general physicals and cancer screenings, and to make a review of vaccination history a part of standard care.&lt;/p&gt;

                     href="http://www.medpagetoday.com/InfectiousDisease/PublicHealth/tb/18380?impressionId=1265787821458"
                     
      &lt;p&gt;WASHINGTON  --  The FDA has approved rosuvastatin (Crestor) for primary prevention of cardiovascular disease, making it the first statin to receive this indication.&lt;/p&gt;
&lt;p&gt;The new labeling, recommended by an FDA advisory panel late last year, also marks the first time that a drug label will include an indication based on the biomarker highly-sensitive C-reactive protein, an inflammatory marker.&lt;/p&gt;
&lt;p&gt;The new indication would be for men 50 or older and women 60 or older who have fasting LDL of less than 130 mg/dL, a highly-sensitive CRP of 2.0 mg/L or greater, triglycerides of less than 500 mg/dL, and no prior history of heart attack or stroke, or coronary heart disease risk.&lt;/p&gt;
&lt;p&gt;The basis for the new labeling was the JUPITER trial, a randomized, placebo-controlled trial of 17,802 men and women with a mean age of 66 and no history of atherosclerosis. All participants had LDL of less than 130 mg/dL and a highly-sensitive C-reactive protein concentration of 2 mg/L or higher.&lt;/p&gt;
&lt;p&gt;Patients were randomized to 20 mg of rosuvastatin for 1.9 years, which reduced median LDL cholesterol to 55 mg/dL, down from a median of 108 mg/dL at baseline. The corresponding relative reduction in the rate of MI, stroke, arterial revascularization, or cardiovascular death was 44% (&lt;em&gt;P&lt;/em&gt;&amp;lt;0.00001).&lt;/p&gt;
&lt;p&gt;The number needed to treat to avoid one cardiovascular event was 25.&lt;/p&gt;
&lt;p&gt;Those results, according to Melvyn Rubenfire, MD, of the University of Michigan, were a &quot;home run for JUPITER,&quot; but it is not clear whether the results would be the same with another statin.&lt;/p&gt;
&lt;p&gt;And there were some risks associated with rosuvastatin, including 13 deaths due to gastrointestinal disorders in the rosuvastatin arm, and 18 patients reported experiencing a &quot;confused state&quot; while taking the drug.&lt;/p&gt;
&lt;p&gt;The most troubling adverse event, however, was an uptick in investigator-reported, new onset diabetes mellitus in the treatment arm, 2.8% versus 2.5%, for a hazard ratio of 1.27 (95% CI 1.05 to 1.53, &lt;em&gt;P&lt;/em&gt;=0.015).&lt;/p&gt;

                     score="0.011"
                     href="http://www.medpagetoday.com/Pediatrics/Vaccines/tb/18348?impressionId=1265787821458"
                     
      &lt;p&gt;Obese adolescents and young adults may not generate an adequate immune response to hepatitis B (HBV) vaccine because the needles used to vaccinate them are too short, a randomized study suggests.&lt;/p&gt;
&lt;p&gt;Immunization with a 1.5-inch needle was associated with 80% higher anti-HBV titers than a 1.0-inch needle, researchers reported online in &lt;em&gt;Pediatrics.&lt;/em&gt;&lt;/p&gt;
&lt;p&gt;The difference persisted in analyses performed to correct for imbalances in the study population.&lt;/p&gt;
&lt;p&gt;&quot;This supports the hypothesis that inadequate muscle penetration is responsible, at least in part, for lower immune response to HBV vaccine among obese adolescent and adult vaccine recipients,&quot; Amy Middleman, MD, of Baylor College of Medicine in Houston, and colleagues concluded.&lt;/p&gt;
&lt;p&gt;Several studies have shown that adolescents and adults with a higher body mass index (BMI) have lower antibody titers after HBV vaccination. The observations have taken on new significance, given that an increasing number of vaccines target a population that has a rising BMI, the authors wrote.&lt;/p&gt;
&lt;p&gt;Researchers hypothesize that standard-length needles do not penetrate through the deltoid fat and into the muscle of obese adolescents and adults. Because of its less abundant blood supply, adipose tissue may delay antigen presentation to B and T cells responsible for immune response, the authors continued.&lt;/p&gt;
&lt;p&gt;To test the hypothesis, Middleman and colleagues conducted a randomized, clinical trial involving adolescents and adults ages 14 to 24 with no prior exposure to HBV vaccine. Eligibility criteria included weight &amp;gt;90 kg for female patients and &amp;gt;120 kg for male patients.&lt;/p&gt;
&lt;p&gt;Patients were randomized to receive the HBV vaccine series with a standard one-inch needle or a 1.5-inch needle. Patients younger than 19 received 0.5-mL injections, and older patients received 1.0-mL injections.&lt;/p&gt;
&lt;p&gt;Investigators used a standardized injection procedure: insertion of the needle at a 90&amp;#176; angle to the deltoid muscle, leaving 2 to 3 mm of needle visible between the skin and the hub.&lt;/p&gt;
&lt;p&gt;Patients received three doses of vaccine at baseline, one month, and four months. Blood samples were obtained at baseline and two months after the final injection.&lt;/p&gt;
&lt;p&gt;The two groups did not differ significantly with respect to median age (21), BMI (~40), deltoid skinfold (41 mm), triceps skinfold (~40 mm), days between vaccine doses one and three (~135), and days from third vaccine dose to titer assessment (65).&lt;/p&gt;
&lt;p&gt;At the end of the study, 24 patients had completed the immunization protocol, 10 in the one-inch group and 14 in the 1.5-inch group.&lt;/p&gt;
&lt;p&gt;Patients vaccinated with a one-inch needle had a median antibody titer of 189.8 mIU/mL compared with 345.4 mIU/mL for patients vaccinated with the 1.5-inch needle (&lt;em&gt;P&lt;/em&gt;=0.03).&lt;/p&gt;
&lt;p&gt;The between-group difference remained significant in analyses that excluded an outlier from the 1.5-inch group (&lt;em&gt;P&lt;/em&gt;=0.047) and that excluded the only two male patients in the study (&lt;em&gt;P&lt;/em&gt;=0.035).&lt;/p&gt;
&lt;p&gt;&quot;As we continue to experience high rates of obesity in the U.S. and throughout the world, additional evidence-based research on optimizing the effective delivery of immunizations to adolescents and young adults will be critical,&quot; the authors wrote.&lt;/p&gt;
&lt;p&gt;&quot;Following updated needle length recommendations will be a first step toward improving the health of our youth and young adults by preventing vaccine-preventable diseases.&quot;&lt;/p&gt;

                     score="0.01"

      &lt;p&gt;Closed-loop insulin delivery systems can improve overnight blood sugar control and reduce hypoglycemia risk in young patients with type 1 diabetes, researchers have found.&lt;/p&gt;
&lt;p&gt;More patients with this &quot;artificial pancreas&quot; maintained target blood glucose levels over the course of the night than those on standard insulin pumps (60% versus 40%), according to Roman Hovorka, MD, of Addenbrooke&apos;s Hospital in Cambridge, England, and colleagues.&lt;/p&gt;
&lt;p&gt;They also avoided significant hypoglycemia events, while those on standard therapy had nine, the researchers reported online in &lt;em&gt;The Lancet&lt;/em&gt;.&lt;/p&gt;
&lt;p&gt;&quot;Overnight closed-loop delivery is appealing because it addresses the issue of nocturnal hypoglycemia,&quot; they wrote.&lt;/p&gt;
&lt;p&gt;Two management strategies for type 1 diabetes  --  continuous glucose monitoring devices and insulin pumps  --  can be combined to form closed-loop systems. This enables delivery of insulin determined by an algorithm using real-time sensor glucose data, rather than preprogrammed rates.&lt;/p&gt;
&lt;p&gt;Unfortunately, few prototypes have been developed, the researchers wrote, because progress has been hindered by suboptimum accuracy and reliability of monitoring devices, slow absorption, and inadequate control algorithms.&lt;/p&gt;
&lt;p&gt;So, to test whether these devices were effective overnight, the researchers conducted three randomized crossover studies at the Wellcome Trust Clinical Research Facility at Addenbrooke&apos;s Hospital in Cambridge.&lt;/p&gt;
&lt;p&gt;They assessed 17 patients, ages 5 to 18, with type 1 diabetes. During 54 nights in the hospital (33 nights on closed-loop devices, and 21 on standard insulin pumps), they monitored three different crossover groups: standard versus closed-loop delivery, closed-loop delivery after rapidly or slowly absorbed meals, and standard versus closed-loop delivery after exercise.&lt;/p&gt;
&lt;p&gt;In the closed-loop scenario, glucose measurements were fed to a control algorithm every 15 minutes, and a nurse adjusted the insulin pump.&lt;/p&gt;
&lt;p&gt;In the first group, the researchers found no significant differences for time in the targeted glucose range or hypoglycemic events (&amp;lt;3.90 mmol/l) between closed-loop and standard delivery (52% versus 39% and 1% versus 2%, respectively).&lt;/p&gt;
&lt;p&gt;Nor were there differences in maintaining the targeted range for closed-loop patients after they ate their meals rapidly or slowly (53% versus 55%).&lt;/p&gt;
&lt;p&gt;&quot;In our studies, postprandial glucose concentrations were increased after large evening meals, but overall glucose control was unaffected and risk of hypoglycemia was low, documenting effective, nonaggressive insulin delivery,&quot; the researchers wrote.&lt;/p&gt;
&lt;p&gt;Patients in the closed-loop delivery group who did early-evening exercises spent the greatest percentage of time in the target blood glucose range, but the improvement was not significant at the corrected level, the researchers said (78% versus 43%).&lt;/p&gt;
&lt;p&gt;&quot;Moderate-intensity, late-afternoon or early-evening exercise in young people is a frequent occurrence and increases glucose requirements in the early morning, exacerbating the risk of nocturnal hypoglycemia,&quot; they wrote. &quot;Our closed-loop algorithm ameliorated this risk and maintained good glucose control.&quot;&lt;/p&gt;
&lt;p&gt;A secondary analysis of pooled data showed increased time in the target range and reduced hypoglycemia episodes for patients with the &quot;artificial pancreas,&quot; compared with those on the regular insulin pump (60% versus 40%, &lt;em&gt;P&lt;/em&gt;=0.002, and 2.1% versus 4.1%, &lt;em&gt;P&lt;/em&gt;=0.03, respectively).&lt;/p&gt;
&lt;p&gt;The closed-loop device also completely prevented blood glucose levels from falling below 3.0 mmol/l, which represents &quot;significant hypoglycemia,&quot; the researchers wrote.&lt;/p&gt;
&lt;p&gt;There were nine such events in the control group.&lt;/p&gt;
&lt;p&gt;They acknowledged that adoption of closed-loop devices is &quot;likely to be gradual,&quot; but &quot;advancements in glucose-sensing technologies could further improve the performance of closed-loop systems.&quot;&lt;/p&gt;
&lt;p&gt;In the future, fully automated closed-loop insulin delivery will &quot;need wireless data transmission to replace manual control of the pump by nurses.&quot;&lt;/p&gt;
&lt;p&gt;In an accompanying editorial, Eric Renard, MD, of the Center Hospitalier Universitaire de Montpellier in France, called the findings a &quot;milestone in the quest for an artificial pancreatic beta-cell that started almost 50 years ago.&quot;&lt;/p&gt;
&lt;p&gt;But he cautioned that glucose control at mealtimes &quot;will now be the challenge for Hovorka and co-workers and other research groups who adopted model predictive control algorithms.&quot;&lt;/p&gt;
&lt;p&gt;&quot;Because of the more complex effects that need to be considered for meal coverage, including the cephalic phase of insulin secretion, incretin&apos;s effects, and the variability of gut glucose absorption from mixed meals, model predictive control algorithms could offer more flexibility than do proportional-integral-derivative algorithms.&quot;&lt;/p&gt;
&lt;p&gt;Meanwhile, Renard wrote, &quot;Overnight closed-loop insulin delivery will hopefully be implemented at home.&quot;&lt;/p&gt;

                     score="0.01"

      Increases in fasting plasma glucose during childhood  --  even though levels remain in the normal range  --  can predict adult prediabetes and type 2 diabetes later in life, a retrospective cohort study showed.&lt;br&gt;
&lt;br&gt;Among individuals with a fasting plasma glucose of less than 100 mg/dL as children, increasing levels were associated with greater risks of prediabetes (&lt;em&gt;P&lt;/em&gt;&amp;lt;0.001) and type 2 diabetes (&lt;em&gt;P&lt;/em&gt;=0.03) in adulthood, according to Gerald Berenson, MD, of Tulane University Health Sciences Center in New Orleans, and colleagues.&lt;br&gt;
&lt;br&gt;There appeared to be a threshold  --  85 mg/dL  --  above which the risk of adult problems began to increase, the researchers reported in the February issue of &lt;em&gt;Archives of Pediatrics and Adolescent Medicine&lt;/em&gt;.&lt;/p&gt;
&lt;p&gt;&quot;It is not surprising that a higher fasting glucose level in childhood predicts prediabetes and diabetes in adulthood,&quot; Matthew Gillman, MD, of Harvard, wrote in an accompanying editorial.&lt;/p&gt;
&lt;p&gt;More surprising, he said, was the existence of the apparent threshold, although &quot;the authors are appropriately circumspect about recommending lowering glucose cutoff points to diagnose children at risk of developing prediabetes or diabetes.&quot;&lt;/p&gt;
&lt;p&gt;&quot;Even if there is a threshold over which children are at substantially higher risk of later prediabetes, it is unclear exactly how high the risk should be to make changing guidelines a good thing,&quot; he wrote. &quot;After all, the right interventions for individuals with prediabetes are still obscure, so identifying more of them may be more trouble than it&apos;s worth.&quot;&lt;/p&gt;
&lt;p&gt;According to Berenson and colleagues, 19 million U.S. adults have type 2 diabetes. More common is a prediabetic state of impaired fasting glucose, affecting about 54 million.&lt;/p&gt;
&lt;p&gt;Previous studies have suggested that higher plasma glucose levels, even if still in the normal range, might be a predictor of diabetes.&lt;/p&gt;
&lt;p&gt;Berenson&apos;s group wanted to see whether elevated fasting plasma glucose in childhood would predict prediabetes or type 2 diabetes in adulthood.&lt;/p&gt;
&lt;p&gt;To find out, they turned to the Bogalusa Heart Study, which began tracking children from that Louisiana town in 1978. All had a fasting plasma glucose lower than 100 mg/dL.&lt;/p&gt;
&lt;p&gt;The current analysis included those same individuals assessed as adults after a mean follow-up of 21 years  --  1,723 were normoglycemic (99 mg/dL or lower), 79 were prediabetic (100 to 125 mg/dL), and 47 had type 2 diabetes.&lt;/p&gt;
&lt;p&gt;Using a childhood fasting plasma glucose of 86 mg/dL or higher as a predictor for prediabetes yielded a 76.9% sensitivity and 85.2% specificity. For diabetes, sensitivity was 75% and specificity was 76%.&lt;/p&gt;
&lt;p&gt;In a multivariate analysis controlling for anthropometric, hemodynamic, and metabolic variables from childhood to adulthood, as well as baseline fasting plasma glucose level, those individuals who had a childhood level 86 mg/dL or higher had increased risks of both prediabetes (OR 3.40, 95% CI 1.87 to 6.18) and type 2 diabetes (OR 2.06, 95% CI 1.01 to 4.23) as adults.&lt;/p&gt;
&lt;p&gt;The authors acknowledged some limitations of the study, including the lack of data on postchallenge glucose, in vivo insulin action and secretion, and glycosylated hemoglobin in childhood.&lt;/p&gt;
&lt;p&gt;Gillman, the editorialist, also noted that the findings&apos; generalizability to children today is unclear because obesity was much less prevalent when the adults in this study were children.&lt;/p&gt;
