AbstractEndometrial cancer is the most common gynaecological malignancy in high-income countries and its incidence is rising. Early detection, aided by highly sensitive and specific biomarkers, has the potential to improve outcomes as treatment can be provided when it is most likely to effect a cure. Sequential window acquisition of all theoretical mass spectra (SWATH-MS), an accurate and reproducible platform for analysing biological samples, offers a technological advance for biomarker discovery due to its reproducibility, sensitivity and potential for data re-interrogation. SWATH-MS requires a spectral library in order to identify and quantify peptides from multiplexed mass spectrometry data. Here we present a bespoke spectral library of 154,206 transitions identifying 19,394 peptides and 2425 proteins in the cervico-vaginal fluid of postmenopausal women with, or at risk of, endometrial cancer. We have combined these data with a library of over 6000 proteins generated based on mass spectrometric analysis of two endometrial cancer cell lines. This unique resource enables the study of protein biomarkers for endometrial cancer detection in cervico-vaginal fluid. Data are available via ProteomeXchange with unique identifier PXD025925.

Gene-Environment Interactions Relevant to Estrogen and Risk of Breast Cancer: Can Gene-Environment Interactions Be Detected Only among Candidate SNPs from Genome-Wide Association Studies?Park, JooYong; email: email@example.com; Choi, Ji-Yeob; email: firstname.lastname@example.org; Choi, Jaesung; email: email@example.com; Chung, Seokang; email: firstname.lastname@example.org; Song, Nan; orcid: 0000-0002-9182-1060; email: email@example.com; Park, Sue K.; orcid: 0000-0001-5002-9707; email: firstname.lastname@example.org; Han, Wonshik; email: email@example.com; Noh, Dong-Young; email: firstname.lastname@example.org; Ahn, Sei-Hyun; email: email@example.com; Lee, Jong Won; email: firstname.lastname@example.org; et al. (MDPI, 2021-05-14)In this study we aim to examine gene–environment interactions (GxEs) between genes involved with estrogen metabolism and environmental factors related to estrogen exposure. GxE analyses were conducted with 1970 Korean breast cancer cases and 2052 controls in the case-control study, the Seoul Breast Cancer Study (SEBCS). A total of 11,555 SNPs from the 137 candidate genes were included in the GxE analyses with eight established environmental factors. A replication test was conducted by using an independent population from the Breast Cancer Association Consortium (BCAC), with 62,485 Europeans and 9047 Asians. The GxE tests were performed by using two-step methods in GxEScan software. Two interactions were found in the SEBCS. The first interaction was shown between rs13035764 of NCOA1 and age at menarche in the GE|2df model (p-2df = 1.2 × 10−3). The age at menarche before 14 years old was associated with the high risk of breast cancer, and the risk was higher when subjects had homozygous minor allele G. The second GxE was shown between rs851998 near ESR1 and height in the GE|2df model (p-2df = 1.1 × 10−4). Height taller than 160 cm was associated with a high risk of breast cancer, and the risk increased when the minor allele was added. The findings were not replicated in the BCAC. These results would suggest specificity in Koreans for breast cancer risk.
No Difference in Penetrance between Truncating and Missense/Aberrant Splicing Pathogenic Variants in MLH1 and MSH2: A Prospective Lynch Syndrome Database StudyDominguez-Valentin, Mev; orcid: 0000-0001-7856-0057; email: Mev.Dominguez.Valentin@rr-research.no; Plazzer, John-Paul; orcid: 0000-0001-5114-4301; email: email@example.com; Sampson, Julian R.; email: Sampson@cardiff.ac.uk; Engel, Christoph; orcid: 0000-0002-7247-282X; email: firstname.lastname@example.org; Aretz, Stefan; orcid: 0000-0002-5228-1890; email: email@example.com; Jenkins, Mark A.; email: firstname.lastname@example.org; Sunde, Lone; email: email@example.com; Bernstein, Inge; email: firstname.lastname@example.org; Capella, Gabriel; orcid: 0000-0002-4669-7320; email: email@example.com; Balaguer, Francesc; orcid: 0000-0002-0206-0539; email: firstname.lastname@example.org; et al. (MDPI, 2021-06-28)Background. Lynch syndrome is the most common genetic predisposition for hereditary cancer. Carriers of pathogenic changes in mismatch repair (MMR) genes have an increased risk of developing colorectal (CRC), endometrial, ovarian, urinary tract, prostate, and other cancers, depending on which gene is malfunctioning. In Lynch syndrome, differences in cancer incidence (penetrance) according to the gene involved have led to the stratification of cancer surveillance. By contrast, any differences in penetrance determined by the type of pathogenic variant remain unknown. Objective. To determine cumulative incidences of cancer in carriers of truncating and missense or aberrant splicing pathogenic variants of the MLH1 and MSH2 genes. Methods. Carriers of pathogenic variants of MLH1 (path_MLH1) and MSH2 (path_MSH2) genes filed in the Prospective Lynch Syndrome Database (PLSD) were categorized as truncating or missense/aberrant splicing according to the InSiGHT criteria for pathogenicity. Results. Among 5199 carriers, 1045 had missense or aberrant splicing variants, and 3930 had truncating variants. Prospective observation years for the two groups were 8205 and 34,141 years, respectively, after which there were no significant differences in incidences for cancer overall or for colorectal cancer or endometrial cancers separately. Conclusion. Truncating and missense or aberrant splicing pathogenic variants were associated with similar average cumulative incidences of cancer in carriers of path MLH1 and path_MSH2.
Knowledge and competency standards for specialized cognitive behavior therapy for adult obsessive-compulsive disorder.Sookman, Debbie; email: email@example.com; Phillips, Katharine A; email: firstname.lastname@example.org; Anholt, Gideon E; email: email@example.com; Bhar, Sunil; email: firstname.lastname@example.org; Bream, Victoria; email: email@example.com; Challacombe, Fiona L; email: firstname.lastname@example.org; Coughtrey, Anna; email: email@example.com; Craske, Michelle G; email: firstname.lastname@example.org; Foa, Edna; email: email@example.com; Gagné, Jean-Philippe; email: firstname.lastname@example.org; et al. (2021-01-27)Obsessive-Compulsive Disorder (OCD) is a leading cause of disability world-wide (World Health Organization, 2008). Treatment of OCD is a specialized field whose aim is recovery from illness for as many patients as possible. The evidence-based psychotherapeutic treatment for OCD is specialized cognitive behavior therapy (CBT, NICE, 2005, Koran and Simpson, 2013). However, these treatments are not accessible to many sufferers around the world. Currently available guidelines for care are deemed to be essential but insufficient because of highly variable clinician knowledge and competencies specific to OCD. The phase two mandate of the 14 nation International OCD Accreditation Task Force (ATF) created by the Canadian Institute for Obsessive Compulsive Disorders is development of knowledge and competency standards for specialized treatments for OCD through the lifespan deemed by experts to be foundational to transformative change in this field. This paper presents knowledge and competency standards for specialized CBT for adult OCD developed to inform, advance, and offer a model for clinical practice and training for OCD. During upcoming ATF phases three and four criteria and processes for training in specialized treatments for OCD through the lifespan for certification (individuals) and accreditation (sites) will be developed based on the ATF standards.
