Q: Worldwide, each year, large numbers of women are referred for colposcopy following low-grade abnormal cervical cytology. Many have no visible abnormality on examination. The risk of cervical intra-epithelial neoplasia grade 2/3 (CIN2/3) in these women is low. It is unknown whether, for women, a normal colposcopy resolves the anxiety which often follows the receipt of an abnormal cytology result. We investigated the prevalence of adverse psychological outcomes over 30\xa0months following a normal colposcopy.', 'This cohort study was nested within the UK TOMBOLA randomized controlled trial. Women aged 20-59\xa0years, with recent low-grade cytology, who had a satisfactory colposcopy examination and normal transformation zone, completed the Hospital Anxiety and Depression Scale (HADS) and Process Outcome Specific Measure (POSM) at recruitment and during follow-up (12, 18, 24 and 30\xa0months post-recruitment). Outcomes included percentages reporting significant anxiety (HADS anxiety subscale score ≥11), significant depression (HADS depression subscale score ≥8) or worries about the result of the next cytology test, cervical cancer, having sex, future fertility and general health at each time point (point prevalence) and during follow-up (cumulative prevalence).', 'The study included 727 women. All psychological measures (except depression) had high prevalence at recruitment, falling substantially by 12\xa0months. During follow-up, the cumulative prevalence of significant anxiety was 27% and significant depression was 21%. The most frequently reported worry was that the next cytology test would be abnormal (cumulative prevalence of 71%; point prevalence of ≥50% at 12 and 18\xa0months). The cumulative prevalence values of worries about cervical cancer, having sex and future fertility were 33%, 20% and 16%, respectively.

Q: To investigate the relationship between tissue elasticity before and after antiviral therapy and shear wave as well as strain elastography.', 'FibroScan and real-time tissue elastography were performed before and after antiviral therapy for chronic hepatitis C, and treatment efficacy and elastographic findings were comparatively analyzed. Elasticity was evaluated by measuring liver stiffness (LS) in kilopascals using FibroScan, and the liver fibrosis index (LFI) was assessed by real-time tissue elastography.', 'LS and LFI correlated well before and after therapy (r = 0.567, p = 0.003 and r = 0.576, p = 0.002, respectively). In the group without a sustained virological response (SVR), LS increased in 4 of 5 patients. Patients with an increase in both LS and LFI were all in the non-SVR group (3/3, 100%). In addition, LS increased in all patients except 1 in the non-SVR group (4/5, 80%). In the SVR group, both LS and LFI decreased in all patients except 1 (18/19, 94.7%). In the patient with an increase in LS despite achieving SVR, LS decreased quickly after alcohol cessation.

Q: Our previous study suggested that N-cadherin was downregulated in hepatocellular carcinoma (HCC). Our aim in this study was to investigate the correlation between N- and E-cadherin expression in HCC and its clinical significance.', 'Eighty-six patients with HCC undergoing liver resection were retrospectively studied. N- and E-cadherin expression in HCC and adjacent liver tissue were investigated using immunohistochemistry and immunofluorescence. The correlation between the expression status of both cadherins and surgical outcomes was analyzed.', 'In 23 patients negative for E-cadherin expression, 19 of them (82.6%) were also negative for N-cadherin expression. In 30 patients with heterogeneous expression of E-cadherin, 20 of them (66.7%) also had heterogeneous expression of N-cadherin. In 33 patients with uniformly positive expression of E-cadherin, 19 of them (57.6%) also had uniformly positive expression of N-cadherin. Therefore, there was a positive correlation between expression patterns of N- and E-cadherins. Concurrent loss of both N- and E-cadherin expressions was significantly associated with absence of the tumor capsule, vascular invasion, and poor differentiation. The 1- and 3-y disease-free survival rates were 27% and 9%, respectively, and the 1- and 3-y overall survival rates were 64.3% and 14.3%, respectively, in patients with concurrent loss of both cadherins, which were significantly worse than those with concurrent uniformly positive expression or heterogeneous expression of both cadherins.
