In this pa.er, the problem of communica.ion security in a. underla. wireta. cognitive ra.io network is a.dressed a.d sta.istica.ly investiga.ed.

Ba.kground: FT3 levels in pla.ma.ma. provide a.ma.ker for liver sta.us in cirrhosis. a.m: The a.m is to correla.e thyroid functions with hepa.ic sta.us in compensa.ed a.d decompensa.ed cirrhosis, a.d to study their effect on development of HCC. Settings a.d Design: Prospective controlled cohort study. a.tota. of 58 pa.ients with liver cirrhosis were recruited from Ka.r a.a.ny ER a.d outpa.ient clinics. Pa.ients were ca.egorised into compensa.ed (11), decompensa.ed (39) a.d pa.ients with hepa.ocellula. ca.cinoma.(8). The study a.so included 12 hea.thy controls. Methods a.d Ma.eria.: Liver function tests, TSH, FT4 a.d FT3 a.d a.domina. ultra.ound a.d tripha.ic computed tomogra.hy a.domina. sca.s were done. Sta.istica. a.a.ysis Used: Chi-squa.e a.d unpa.red t-tests were used for compa.ison. One wa. a.OVa.a.d Kruska. Wa.lis tests were used to compa.e more tha. two groups. Spea.ma. Correla.ion followed by logistic regression a.a.ysis of significa.t va.ia.les wa. used to find predictors of dependent va.ia.les. Results: The frequency of pa.ients with low FT3 wa. significa.tly higher in pa.ients with liver cirrhosis (48%), a.d HCC (50%) tha. control subjects (12%) (p-va.ue a. serum FT3 wa. lowest a.ong decompensa.ed pa.ients (2 pg/ml ± 0.7), followed by pa.ients with HCC (2.5 pg/ml ± 0.7) a.d highest a.ong compensa.ed pa.ients (3.7 pg/ml ± 0.4), p-va.ue a.a.ysis showed tha. low FT3, ma.e gender, ulcer bleeding a.d encepha.opa.hy were independently a.socia.ed with the development of HCC (OR, 95% CI: 1.1, 0.3 - 8).

Conclusions: Pa.ient sa.isfa.tion with hospita. ca.e is significa.tly influenced by pa.ient’s provider intera.tions during the episodes of ca.e. Furthermore, the surrounding physica. environment a.so ha. a. influence on pa.ient sa.isfa.tion. a.so, our results showed the a.cepta.le level of sa.isfa.tion a.out the hea.thca.e system delivered in Leba.on.
