ment Program (NSQIP) provides riskadjusted outcome measures for participating hospitals to use for performance improvement. This article summarizes its history and reports the two projects on postoperative respiratory complications-intubation >48 and pneumonia. It also explains the benefit of a severalhospital collaborative and describes development of a "playbook."

MDR1 Gene Polymorphisms and Expressionas by chemotherapeutic drugs. Thus our findings suggest that inter individual variability in platinum based therapy may be anticipated by MDR1 genotypes. Further studies on a large number of samples shall eventually lead to provide beneficial information for the individualized chemotherapy.
Background: An important candidate gene for diabetic retinopathy (DR) is vascular endothelial growth factor (VEGF). The VEGF gene is extremely polymorphic. The 18 base pairs (bp) segment (I/D) polymorphism at -2549 position of the promoter region is of great importance.
Aim:The present study aimed to identify VEGF (I/D) polymorphism in DM and DR patients.
Materials and Methods:This cross section study involved 100 healthy control subjects, 100 diabetes mellitus (DM) subjects and 100 DR subjects. Blood samples were collected after informed consent of study subjects, DNA extraction was performed using inorganic method, VEGF gene promoter region that was confirmed using 2% agarose gel. Polymerase Chain Reaction (PCR) was used to identify (I/D) polymorphism of 18 bp fragment at position -2549, DNA Sequencing was done commercially to confirm the presence of 18bp I/D polymorphism. The allele (I/D) and genotypes (DD, I/D, II) frequencies of VEGF gene were compared among all the study subjects.
Results:The frequency of DD genotype in DR was 52% while in DM was 40% and in control was 2%. The significant differences (p<0.05) were observed when genotypes were compared among control and DM, DM and DR, Control and DR. The significant differences (p<0.05) were observed in Control and DM Control and DR, DM and DR at 95% CI.
Conclusion:These findings suggest that the DD genotype is possible risk factor for development and progression of retinopathy as compared to uncomplicated subject II genotype in local population.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
