BACKGROUND As new, higher-priced vaccines are added to the immunization schedule, Vaccines for Children (VFC) program costs are increasing and attention has been focused on strengthening accountability. In New York City, the VFC program distributes publicly purchased vaccines, worth nearly $117 million annually, to more than 1,500 enrolled facilities to(More)
Microencapsulation may allow for immunosuppression-free islet transplantation. Herein we investigated whether human islets can be shipped safely to a remote encapsulation core facility and maintain in vitro and in vivo functionality. In non-encapsulated islets before and encapsulated islets after shipment, viability was 88.3+/-2.5 and 87.5+/-2.7% (n=6,(More)
Human islet isolation outcomes were compared between two purification methods; 32 pancreases were processed by conventional Biocoll purification method (SM, standard method) and 132 pancreases by a refined University of Illinois at Chicago UW/Biocoll method (UIC-UB). There was no difference in donor characteristics between the two study groups. The(More)
This study was designed to compare Histadine-Tryptophan-Ketogluterate (HTK) with University of Wisconsin (UW) solution. Pancreata from extended criteria donors were flushed and transported with HTK (n=41) or UW (n=45). Isolation outcomes were determined by islet yields, viability and in vitro and in vivo function. Final yields were similar between two(More)
OBJECTIVES To investigate adolescent vaccination in New York City, we assessed tetanus, diphtheria, and acellular pertussis (Tdap), meningococcal conjugate (MCV4), and human papillomavirus (HPV) vaccine uptake, vaccine co-administration, and catch-up coverage over time. METHODS We analyzed data from the Citywide Immunization Registry, a population-based(More)
OBJECTIVES We determined the success of the school-located vaccination (SLV) program, implemented in 2009 in New York City to deliver pandemic influenza A (H1N1) monovalent vaccine (pH1N1), versus provider offices in reaching children who had never previously received influenza vaccine. METHODS We compared the immunization history of children vaccinated(More)
The analysis of blood oxygen level-dependent (BOLD) signals in humans at rest has revealed the existence of large, spontaneous fluctuations synchronized between different brain regions. This phenomenon is called functional connectivity (FC). Functionally connected brain regions form different brain networks known as resting-state networks, which are(More)
