Discoveries in the first few years of the 21st century have led to an understanding of important interactions between the nervous system and the inflammatory response at the molecular level, most notably the acetylcholine (ACh)- triggered,α7-nicotinic acetylcholine receptor (α7nAChR)- dependent nicotinic antinflammatory pathway. Studies using the α7nAChR agonist, nicotine, for the treatment of mucosal inflammation have been undertaken but the efficacy of nicotine as a treatment for inflammatory bowel diseases remains debatable. Further understanding of the nicotinic anti-inflammatory pathway and other endogenous anti-inflammatory mechanisms is required in order to develop refined and specific therapeutic strategies for the treatment of a number of inflammatory diseases and conditions, including periodontitis, psoriasis, sarcoidosis, and ulcerative colitis. 展开更多

The purpose of this study was to identify vaccination patterns of both general pediatricians and subspecialists with regards to their own children and projected progeny. A 14 question survey was sent randomly to 1000 members of the Academy of Pediatrics in 2009. Two categories of questions included 1) how physicians with children vaccinated them in the past, and 2) how all respondents would vaccinate a child in 2009. A comparison was made between the answers of general and specialty pediatricians. 582 valid questionnaires were received (58.2% response rate) of which 431 were general pediatricians and 151 subspecialists. No statistical difference was found between general and specialty pediatricians on how they vaccinated their children up until 2009 (95% vs 93%). When asked about vaccinating a future child, a significant proportion of respondents would deviate from CDC guidelines, specialists more than general pediatricians (21% vs 9%). Generalists were more likely to give a future child Hepatitis A (OR: 3.6;95% CI 1.3 - 10.4), Rotavirus (OR: 2.2;95% CI 1.1 - 4.4), Meningococcal (OR: 9.9;95% CI 3.3-29.9), and influenza (OR: 5.4;95% CI 1.1 - 26.7) vaccines. Specialists were more likely to postpone MMR vaccinetion (OR: 4.4 95% CI 2.3 - 8.6). Safety was listed by both groups as the most common reason for altering the recommended immunization schedule. Until 2009, general pediatricians and pediatric specialists have largely adhered to ACIP recommendations, but due to vaccine safety and other concerns, both groups, albeit a higher percentage of specialists, reported greater numbers willing to diverge from these recommendations. 展开更多
