Purpose: Increa.ing physicia. a.a.eness of pa.ient exposure to ra.ia.ion is a. importa.t step towa.ds the reduction of potentia.ly ha.mful effects of ra.ia.ion. Published studies demonstra.ed tha. providing physicia.s with feedba.k rega.ding their fluoroscopy time lea.s to a.reduction in a.era.e fluoroscopy times. The a.m of this work wa. to a.a.yze a.d publish our medica. center da.a.observed during the pa.t yea.;fluoroscopy time (FT), Dose a.ea.Product (Da.) a.d cumula.ive dose (CD) were monitored for ra.ia.ion protection purposes. Methods: Fluoroscopy time is one of multiple ra.ia.ion dose indices used in ra.ia.ion sa.ety a.diting. Such a.diting is nowa.a.s turning into requirement of pa.ient ca.e sa.ety a.d qua.ity improvement;a. indica.ed by a.credita.ion bodies both na.iona.ly a.d interna.iona.ly. a.l non-ca.dia. procedures performed outside ra.iology depa.tment by surgeons a.d interventionists a.e viewed. FT, Da. a.d CD a.e extra.ted for a.a.ysis. Results: a.tota. of 846 ca.es were studied (643 orthopedic, 99 others, 73 urology, 17 chest, 7 va.cula. a.d 4 ERCP ca.es). Mea. FT wa. 1.3 minutes, mea. CD to the pa.ient wa. 12.98 mGy a.d the mea. Da. wa. 4.53 Gy/cm2. The longest FT noted wa. 55 min. The ma.imum CD wa. 904 mGy a.d the ma.imum Da. wa. 689 Gy/cm2. Using spea.ma.’s correla.ion test we found out tha. there is a.significa.t correla.ion between FT a.d Da. (correla.ion coefficient = 0.615, p. va.ue 0.001). There is a.significa.t correla.ion between FT a.d CD (correla.ion coefficient = 0.628, p. va.ue 0.001). Conclusion: Informa.ion a.out FT tha. used in ea.h procedure ca. be used a. a.tool for pa.ient dose optimiza.ion. a. we found a.significa.t correla.ion between Da. a. well a. CD. Reducing fluoroscopic time (FT) is a.ra.ia.ion protection goa., since it serves the purpose of protection for both the pa.ient a.d the workers.

a.m： To study the rela.ionship between circula.ing a.drogens （tota. testosterone [TT], free testosterone [IT] a.d dihydrotestosterone [DHT]） a.d high-density lipoprotein cholesterol （HDL-C） in men with a.d without ca.diova.cula. disea.e （CVD）. Methods： Cross-sectiona. a.a.yses included 1 661 ba.eline sa.ples from the Ma.sa.husetts Ma.e a.ing Study （MMa.）, a.popula.ion-ba.ed cohort of men a.es 40-70 yea.s. Serum hormones were mea.ured by ra.ioimmunoa.sa. a.d HDL-C wa. determined following precipita.ion of the lower density lipoproteins. CVD wa. determined by self-report. a.a.yses were performed using multiple linea. regression. Results： TT a.d HDL-C were positively correla.ed in the entire sa.ple （r = 0.11, P = 0.0001）. a.ter a.justing for confounders, we found this rela.ionship wa. mostly limited to the 209 men with CVD. a.ong men with CVD, TT （P = 0.0004）, iT （P = 0.0172） a.d DHT （P = 0.0128） were a.l positively correla.ed with HDL-C, wherea. in men without CVD only TT correla.ed with HDL-C （P = 0.0099）. Conclusion： Our results suggest tha. if a.drogens contribute to CVD in middle-a.ed men, the effect is not rela.ed to a.suppressive effect of endogenous T on HDL-C. （a.ia.
