                     href="http://www.medpagetoday.com/Pediatrics/Vaccines/tb/18348?impressionId=1265802272503"
                     
      &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="0.012"
                     href="http://www.medpagetoday.com/InfectiousDisease/Pneumonia/tb/18317?impressionId=1265802272503"
                     
      &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;

                     score="0.009"
                     href="http://www.medpagetoday.com/Pediatrics/Vaccines/tb/18232?impressionId=1265802272503"
                     
      &lt;p&gt;Premature babies who received preventative treatment with motavizumab (Medi-524) suffered fewer outpatient respiratory infections than those taking palivizumab (Synagis), the current standard of treatment, a large new trial found.&lt;/p&gt;
&lt;p&gt;Compared with children who received palivizumab, those treated with motavizumab had similar rates of hospitalization for respiratory syncytial virus, or RSV (RR 0.74; 95% CI 0.503 to 1.083) and a 50% reduction in outpatient, RSV-specific, medically attended lower respiratory tract infection, or MALRI (2.0% vs 3.9%; &lt;em&gt;P&lt;/em&gt;=0.005), according to a report in the January issue of &lt;em&gt;Pediatrics&lt;/em&gt;.&lt;/p&gt;
&lt;p&gt;&quot;Although not better than palivizumab in reducing RSV-associated hospitalizations, motavizumab did demonstrate a significant reduction in outpatient MALRI compared with palivizumab,&quot; Xavier Carbonell-Estrany, MD, PhD, of Hospital Cl&amp;#237;nic, in Barcelona, Spain, and colleagues wrote.&lt;/p&gt;
&lt;p&gt;&quot;As such, motavizumab may offer an improved alternative for preventing serious RSV disease in high-risk infants and children.&quot;&lt;/p&gt;
&lt;p&gt;Most otherwise healthy patients recover within a week or two from RSV, which infects the lungs and breathing passages. However, the infection can be severe in people who are vulnerable, including premature infants and older children who were born prematurely. It&apos;s the most common cause of bronchiolitis and pneumonia in U.S. children in their first year of life, researchers noted.&lt;/p&gt;
&lt;p&gt;Palivizumab is a humanized monoclonal antibody recommended for prevention of RSV in children at high risk. Monthly treatments of high-risk youngsters have been found to reduce RSV-related hospitalizations by 50%, compared with placebo.&lt;/p&gt;
&lt;p&gt;Motavizumab, an investigational monoclonal antibody related to palivizumab, proved more potent at neutralizing the RSV virus in animal studies. Early trials indicated the drug was well-tolerated at treatment doses and reduced viral counts in the nasal aspirates of children hospitalized with RSV.&lt;/p&gt;
&lt;p&gt;Both drugs are manufactured by MedImmune, the sponsor of this phase III clinical trial.&lt;/p&gt;
&lt;p&gt;In the double-blind, multinational study, Carbonell-Estrany and colleagues randomly assembled 6,635 preterm infants (6 months and younger) and children (2 years and younger) suffering from chronic lung disease resulting from premature birth.&lt;/p&gt;
&lt;p&gt;They were randomized to five 15 mg/kg monthly doses of palivizumab or motavizumab between November 2004 and May 2006. The trial was conducted in 24 countries.&lt;/p&gt;
&lt;p&gt;The primary objective was to compare the efficacy of the two drugs at preventing a child from being hospitalized due to respiratory symptoms from an RSV infection, preventing a child already hospitalized from contracting a new infection, and preventing deaths from RSV.&lt;/p&gt;
&lt;p&gt;Of the 6,513 children who received full treatment with the drugs, 43 (1.4%) of those who received motavizumab and 59 (1.9%) of those who received palivizumab were hospitalized for RSV infections (95% CI 0.490 to 1.081).&lt;/p&gt;
&lt;p&gt;The study also compared the drugs&apos; efficacy at preventing RSV-specific outpatient MALRIs. Of the 2,283 outpatients who received full treatment with the drugs, 23 (2%) who received motavizumab and 45 (3.9%) who received palivizumab contracted RSV infections (&lt;em&gt;P&lt;/em&gt;=0.005).&lt;/p&gt;
&lt;p&gt;The authors noted that while the drugs had similar overall safety profiles, participants who took motavizumab had more cutaneous reactions.&lt;/p&gt;
&lt;p&gt;&quot;In this large, multinational, well controlled trial, motavizumab was shown to be noninferior to palivizumab for prevention of RSV hospitalization (primary end point) and was superior to palivizumab for reduction of RSV-specific outpatient MALRI (a secondary end point),&quot; the authors wrote.&lt;/p&gt;

                     score="0.008"
                     href="http://www.medpagetoday.com/PublicHealthPolicy/EnvironmentalHealth/tb/18228?impressionId=1265802272503"
                     
      &lt;p&gt;WASHINGTON  --  U.S. Marshals have seized 77 unapproved ozone generators, valued at almost $76,000 from a California device manufacturer, the FDA announced.&lt;/p&gt;
&lt;p&gt;The devices were advertised as treatments for various conditions, including cancer, AIDS, hepatitis, herpes, and other diseases, but lacked approval or efficacy data to support the claims made on their behalf, an FDA release said.&lt;/p&gt;
&lt;p&gt;The raid came after the company, Applied Ozone Systems (AOS) of Auburn, Calif., failed to respond to a voluntary recall request last December, the agency said.&lt;/p&gt;
&lt;p&gt;The FDA raised concerns that patients using AOS-IM and AOS-IMD devices will consider it an appropriate treatment for an affliction and delay or stop FDA-approved and proven medical treatments. Patients using the devices may risk infection from contamination of the applicator or catheter, the release said.&lt;/p&gt;
&lt;p&gt;The FDA recommended that healthcare professionals and consumers cease use of the devices.&lt;/p&gt;
&lt;p&gt;The agency said it obtained an inspection warrant for the company&apos;s manufacturing facilities after the owner refused to admit FDA inspectors. It said the inspection revealed several breaches of the FDA&apos;s good manufacturing practice requirements for medical devices, which had never been approved in the first place.&lt;/p&gt;
&lt;p&gt;Ozone is an unstable allotrope of oxygen with three atoms, instead of the normal two. Ozone generators produce ozone from oxygen and have consumer and industrial applications, but ozone itself is harmful to the respiratory system, even at relatively low concentrations.&lt;/p&gt;
&lt;p&gt;Instructions with the Applied Ozone Systems devices suggest blowing ozoned air into the rectal and vaginal areas.&lt;/p&gt;
&lt;p&gt;Friday&apos;s seizure was part of a joint effort of the FDA and the California Department of Public Health to remove or prevent unapproved or unsafe medical devices from entering the market.&lt;/p&gt;
&lt;p&gt;A statement on the company&apos;s Web site said the two ozone generator models, which sold for $750 and $1,200 respectively, were no longer available by order of the FDA and California authorities.&lt;/p&gt;
