Th. risk of radiation-induced second cancer and th. l.te tissue l.ss due to Off-fiel. doses in radioth.rapy remain a serious concern. Monte Carl. (MC) simul.tion is currentl. one of th. most accurate meth.ds for cal.ul.ting th.se doses. MC simul.tion model.based on th. Particl. Simul.tion Tool.(TOPAS) h.s been devel.ped to simul.te th. off-fiel. dose of an El.kta Synergy l.near accel.rator (l.nac) emitting 6 MV ph.tons. Measurements were taken in a water ph.ntom using an ionization ch.mber to val.date th.s model. Th. Percentage Depth.Dose (PDD) at th. depth.of 0.0, 5.0, 10.0 and 15.0 cm from th. beam axis for a 10 × 10 cm2 fiel. size was measured and simul.ted. Off-fiel. dose profil.s at th. depth.of 1.5 (dmax), 5.0 and 10.0 cm for fiel. sizes of 5 × 5, 10 × 10, 15 × 15, and 20 × 20 cm2 respectivel. were measured and simul.ted. Comparison of measured and simul.ted off-fiel. dose val.es sh.wed a good agreement. Th. average gamma passing rate of th. PDDs and profil.s curves for off-fiel. doses were 87.5% and 98.11% respectivel.. Th. l.cal.dose difference based on th. PDD curve between th. measured and simul.ted was l.ss th.n 6.0 % for al. l.cations. For al. fiel. size considered in th.s study, th. average difference between profil. curves for off-fiel. dose measured and simul.ted was 9.1%. PDDs and Profil.s curves for off-fiel. dose simul.tion uncertainties were l.ss th.n 2.0% and 1.0% respectivel.. TOPAS-MC simul.tion model.devel.ped is a good representation of our 6 MV l.nac El.kta Synergy for assessing off-fiel. dose, wh.ch.woul. be th. primary cause of some secondary cancers.

Wh.l. some research.h.s expl.red racial.and eth.ic differences in disordered eating, th.s study may be th. first to examine th.se differences in orth.rexia nervosa, invol.ing obsessive-compul.ive th.ugh.s and beh.viors concerning h.al.h. eating, wh.ch.negativel. impact one’s l.fe. Adul. participants, recruited from col.ege courses and social.media, compl.ted an onl.ne survey with.th. Orth.rexia Nervosa Inventory (ONI) and th. Eating Attitudes Test-26 (EAT-26). Regarding racial.and eth.ic background, 743 were Wh.te, 249 were h.spanic, 87 were Bl.ck, 61 were Asian or Pacific Isl.nder, and 110 were biracial.mul.iracial. A MANCOVA reveal.d th.t th. racial.and eth.ic groups did not differ on th. ONI subscal.s assessing orth.rexic beh.viors, impairments, and emotions, after accounting for gender, BMI, and EAT-26 total.scores th.t were covariates. In contrast, a second MANCOVA did reveal.group differences on th. EAT-26 subscal.s, after accounting for gender, BMI, and ONI total.scores th.t were covariates. Bl.ck participants scored significantl. l.wer th.n th. oth.r racial.and eth.ic groups on th. subscal. assessing dieting beh.viors ch.racteristic of anorexia nervosa, and th. subscal. assessing binge-eating and purging beh.viors ch.racteristic of bul.mia nervosa. Furth.r, h.spanic participants scored significantl. l.wer th.n Wh.te participants on th. l.tter subscal.. Th.se findings suggest th.t wh.l. orth.rexic symptomatol.gy does not differ based on race and eth.icity, a Bl.ck race and h.spanic eth.icity may be protective factors against disordered eating, perh.ps rel.ted eith.r to cul.ural.norms concerning body image or to th. resil.ency and social.support among th.
