Activation and inactivation of nuclear factor of kappa light chain gene enhancer in B cells (NFKB) is tightly regulated to ensure effective onset and cessation of defensive inflammatory signaling. However, mutations within NFKB, or change in activation and inactivation molecules have been reported in a few cancers. Although oral squamous cell carcinoma is one of the most prevalent forms of cancer in India, with a development associated with malignant transformation of precancerous lesions, the genetic status of NFKB and relative rates of change in oral precancerous lesions remain unknown. Hence in the present study we investigated all twenty four exons of NFKB gene in two precancerous lesions, namely oral submucous fibrosis (OSMF) and oral leukoplakia (OL) to understand its occurrence, incidence and assess its possible contribution to malignant transformation.', 'Chromosomal DNA isolated from twenty five each of OSMF and OL tissue biopsy samples were subjected to PCR amplification with intronic primers flanking twenty four exons of the NFKB gene. The PCR amplicons were subsequently subjected to direct sequencing to elucidate the mutation status.', 'Sequence analysis identified a novel heterozygous mutation, c.419T>A causing substitution of leucine with glutamine at codon 140 (L140Q) in an OL sample.

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.

It has been argued that carotid intima-media thickness (IMT) could better reflect an adaptive response of the vessel wall rather than being a marker of atherosclerosis. We explore this hypothesis by analyzing the ARTICO data.', 'The ARTICO study was designed to evaluate the prognostic value of the pathological ankle-brachial index (ABI) for the emergence of new vascular events in patients who have suffered a noncardioembolic stroke. Collected variables were as follows: vascular risk factors, mean waist perimeter, quantification of carotid IMT, characteristics of carotid plaques, ABI, and presence of microalbuminuria.', "A total of 591 patients with a complete carotid evaluation were available. There was no correlation between ABI and IMT (Spearman's, p NS). Logistic regression revealed that pathological ABI correlated significantly only with internal carotid artery stenosis\u2009greater than or equal to\u200950% (OR [odds ratio] 2.80, 1.66-4.71, P\u2009<\u2009.01) and peripheral artery disease (OR 3.33, 1.63-6.78, P\u2009<\u2009.01). However, multivariate regression analysis demonstrated that carotid IMT was independently associated with age (OR 1.05, 95% confidence interval [CI] 1.02-1.09, P\u2009<\u2009.01), hypertension (OR 1.83, 95% CI 1.02-3.26, P\u2009=\u2009.04), waist circumference (OR 1.03, 95% CI 1.01-1.05, P\u2009<\u2009.01), and microalbuminuria (OR 2.02, 95% CI 1.22-3.35, P\u2009<\u2009.01).
