WHAT'S KNOWN ON THIS SUBJECT: The reasons why teens are not immunized are related to parental lack of knowledge and the need for provider recommendations. WHAT THIS STUDY ADDS:The reasons for vaccine refusal for human papillomavirus vaccine differ from other teen vaccines, and concerns about its safety are increasing over time.abstract OBJECTIVE: To determine the reasons adolescents are not vaccinated for specific vaccines and how these reasons have changed over time. METHODS:We analyzed the 2008-2010 National Immunization Survey of Teens examining reasons parents do not have their teens immunized. Parents whose teens were not up to date (Not-UTD) for Tdap/Td and MCV4 were asked the main reason they were not vaccinated. Parents of female teens Not-UTD for human papillomavirus vaccine (HPV) were asked their intent to give HPV, and those unlikely to get HPV were asked the main reason why not. RESULTS:The most frequent reasons for not vaccinating were the same for Tdap/Td and MCV4, including "Not recommended" and "Not needed or not necessary." For HPV, the most frequent reasons included those for the other vaccines as well as 4 others, including "Not sexually active" and "Safety concerns/Side effects." "Safety concerns/Side effects" increased from 4.5% in 2008 to 7.7% in 2009 to 16.4% in 2010 and, in 2010, approaching the most common reason "Not Needed or Not Necessary" at 17.4% (95% CI: 15.7-19.1). Although parents report that health care professionals increasingly recommend all vaccines, including HPV, the intent to not vaccinate for HPV increased from 39.8% in 2008 to 43.9% in 2010 (OR for trend 1.08, 95% CI: 1.04-1.13).CONCLUSIONS: Despite doctors increasingly recommending adolescent vaccines, parents increasingly intend not to vaccinate female teens with HPV. The concern about safety of HPV grew with each year. Addressing specific and growing parental concerns about HPV will require different considerations than those for the other vaccines.

Sarcoidosis is a systemic inflammatory disease characterized by the formation of granulomas in affected organs. Genome-wide association studies (GWASs) of this disease have been conducted only in European population. We present the first sarcoidosis GWAS in African Americans (AAs, 818 cases and 1,088 related controls) followed by replication in independent sets of AAs (455 cases and 557 controls) and European Americans (EAs, 442 cases and 2,284 controls). We evaluated >6 million SNPs either genotyped using the Illumina Omni1-Quad array or imputed from the 1000 Genomes Project data. We identified a novel sarcoidosis-associated locus, NOTCH4, that reached genome-wide significance in the combined AA samples (rs715299, P AA-meta = 6.51×10−10) and demonstrated the independence of this locus from others in the MHC region in the same sample. We replicated previous European GWAS associations within HLA-DRA, HLA-DRB5, HLA-DRB1, BTNL2, and ANXA11 in both our AA and EA datasets. We also confirmed significant associations to the previously reported HLA-C and HLA-B regions in the EA but not AA samples. We further identified suggestive associations with several other genes previously reported in lung or inflammatory diseases.

Among a small convenience sample of unmotivated cigarette smokers, EC experimentation and 1 week of ad libitum use increased readiness and confidence to quit regular cigarettes and reduced regular cigarette smoking.

IntroductionExposure to non-communicable disease (NCD) risk factors is increasing among adolescents in most countries due to demographic, economic and epidemiological forces. We sought to analyse the potential health impact and costs of implementing NCD risk reduction interventions among adolescents worldwide.MethodsWe identified six interventions targeted at adolescent tobacco smoking, heavy episodic drinking and obesity and supported by effectiveness and cost-effectiveness evidence. Based on a population-level cohort of adolescents in 70 representative countries, we assessed the global mortality consequences of fully implementing these interventions over 2020–2070 using the potential impact fraction approach. We calculated the economic benefits of reduced mortality and estimated the required financial costs, discounting both at 3% annually. We also conducted best-case and worst-case scenario analyses.ResultsFull implementation of these interventions worldwide could avert nearly 10% of premature deaths among this cohort, translating to about US$400 billion in cumulative economic benefits. Cumulatively, the required costs would be about US$85 billion, suggesting that every US$1 of public money invested would generate US$5 in increased human capital. Tobacco taxes generally conferred the highest economic returns; however, an in-depth analysis of three countries illustrated the potential for different priorities, such as alcohol control, to emerge.ConclusionFrom a life course perspective, implementation of a package of interventions to reduce NCD risk among adolescents worldwide would substantially reduce premature mortality at reasonable costs. Our analysis illustrates the importance of integrating NCD prevention policies into the emerging global agenda for adolescent health and well-being.

Mechanical stress induced by contractions constantly threatens the integrity of muscle Z-disc, a crucial force-bearing structure in striated muscle. The PDZ-LIM proteins have been proposed to function as adaptors in transducing mechanical signals to preserve the Z-disc structure, however the underlying mechanisms remain poorly understood. Here, we show that LDB3, a well-characterized striated muscle PDZ-LIM protein, modulates mechanical stress signaling through interactions with the mechanosensing domain in filamin C, its chaperone HSPA8, and PKCα in the Z-disc of skeletal muscle. Studies of Ldb3Ala165Val/+ mice indicate that the myopathy-associated LDB3 p.Ala165Val mutation triggers early aggregation of filamin C and its chaperones at muscle Z-disc before aggregation of the mutant protein. The mutation causes protein aggregation and eventually Z-disc myofibrillar disruption by impairing PKCα and TSC2-mTOR, two important signaling pathways regulating protein stability and disposal of damaged cytoskeletal components at a major mechanosensor hub in the Z-disc of skeletal muscle.

In Oklahoma, in contrast to recent national studies, obesity is increasing among certain groups of low-income preschool children. These findings suggest geographic diversity in obesity and that state-specific obesity surveillance is important to help target interventions to those at highest risk.
