    Body fat distribution is a heritable trait and a well-established predictor of adverse metabolic outcomes, independent of overall adiposity. To increase our understanding of the genetic basis of body fat distribution and its molecular links to cardiometabolic traits, here we conduct genome-wide association meta-analyses of traits related to waist and hip circumferences in up to 224,459 individuals. We identify 49 loci (33 new) associated with waist-to-hip ratio adjusted for body mass index (BMI), and an additional 19 loci newly associated with related waist and hip circumference measures (P < 5 × 10(-8)). In total, 20 of the 49 waist-to-hip ratio adjusted for BMI loci show significant sexual dimorphism, 19 of which display a stronger effect in women. The identified loci were enriched for genes expressed in adipose tissue and for putative regulatory elements in adipocytes. Pathway analyses implicated adipogenesis, angiogenesis, transcriptional regulation and insulin resistance as processes affecting fat distribution, providing insight into potential pathophysiological mechanisms

    Agreement between colposcopic impression and histological diagnosis among human papillomavirus type 16-positive women: A clinical trial using dynamic spectral imaging colposcopy

    Summarization: To investigate the agreement between conventional colposcopic impression, dynamic spectral imaging (DSI) colposcopy and histology, for human papillomavirus type 16-positive (HPV16(+)) and non-16 high-risk (hr) HPV(+) women. Prospective, comparative, multicentre clinical trial. Three colposcopy clinics in the Netherlands. Women (n = 177) aged 18 years or over with an intact cervix, referred for colposcopy. The colposcopist graded the lesion by using the DSI colposcope as a regular video colposcope. Subsequently the DSI impression was displayed and biopsies were taken from all abnormal areas as well as from a random (normal) site. A cervical smear was taken for HPV typing. Histologically confirmed high-grade cervical intraepithelial neoplasia or cancer (CIN2(+)), positive for HPV16 or for any other hrHPV type. The DSI colposcope identified more CIN2(+) cervical lesions among HPV16(+) women than in non-16 hrHPV(+) women (P = 0.032 regardless of final histology and P = 0.009 among women with CIN2(+)). Consequently, the sensitivity of the DSI colposcope for detecting CIN2(+) lesions was higher in HPV16(+) women than in non-16 hrHPV(+) women (97% versus 74%, P = 0.009). No such differences were seen for the colposcopist impression. In addition, mainly smaller cervical lesions are missed by the colposcopist. The sensitivity of DSI colposcopy for CIN2(+) is higher in HPV16(+) than in non-16 hrHPV(+) women. Furthermore, regardless of HPV16 status, the sensitivity of DSI for CIN2(+) is higher than that of the colposcopist, probably because colposcopists tend to miss smaller cervical lesions.Presented on: BJOG: An International Journal of Obstetrics and Gynaecolog
