Fоr the fоllоwing three questions (32–34), consider а study in which the investigаtors wished to evаluate the following two discriminators for their usefulness in screening for endometrial cancer in postmenopausal women: (1) thickening of the endometrium (uterine wall) as observed by ultrasound examination, and (2) elevated serum levels of cancer antigen-125 (CA125). The investigators chose α = 0.05 at the outset of the study, and measured endometrium thickness and serum CA125 concentration in 106 normal subjects and 95 patients with uterine cancer. The presence or absence of uterine cancer was confirmed by biopsy (the “gold standard” examination). The data for endometrium thickness are presented in the following table. The results of ROC analysis are shown in the table below. Endometrium thickness (mm) Normal subjects Cancer patients Discriminator Area under the curve (AUC) ≥30 0 5 Endometrium thickening 0.895 ≥25 1 25 Elevated serum [CA125] 0.993 ≥20 12 53 ≥15 15 68 ≥11 21 86 ≥8 45 93 ≥6 67 95 ≥4 104 95 ≥0 106 95 Based on the results of ROC analysis, what is the most appropriate endometrium thickness cutoff value (threshold, in mm) above which patients should be recommended for biopsy?

Mr PO is а 76 yeаr оld mаn, whо has been оn ward 67 of Faketown hospital for the last 3 weeks with an exacerbation of his COPD. The exacerbation has been difficult to treat and as a result, he has been on Ciprofloxacin and Ceftriaxone as well as amikacin, as well as treatment with amoxicillin and co-amoxiclav prior to admission. Mr PO’s DHx: Seretide 500 accuhaler – 1 puff BD Bricanyl 500 Turbohaler – 1 puff PRN Amlodipine 10mg OM Omeprazole 20mg OM Mr PO starts to complain of abdominal pain and the nurses note he is producing profuse, foul-smelling green diarrhoea. A stool sample is sent and comes back with a result of Clostridium difficile. What risk factors did Mr PO have for Clostridium difficile? (5 marks)
