This is a systematic review and meta-analysis evaluating the uptake of cascade genetic testing for hereditary breast and ovarian cancer syndrome. Among 30 studies included for meta-analysis, the uptake of cascade genetic testing was 33% (95% CI 25%-42%), with higher uptake rates among females compared with male relatives, and among first-degree compared with second-degree relatives. These findings indicate suboptimal uptake of cascade genetic testing among people at risk for hereditary breast and ovarian cancer syndrome, representing a missed opportunity for cancer prevention and early detection.

The current paradigm relies on patient coordinated care, resulting in only one-third of relatives successfully completing testing. Studies suggest that team-based approaches, where clinicians facilitate testing, can increase uptake.

Methods And Analysis: Our primary objective is to use a two-arm, single-institution randomised controlled trial to compare the proportion of eligible patients that are recommended genetic testing for hereditary cancer syndromes using a digital tool versus clinician interview for genetic cancer risk assessment in an urban academic gynaecology clinic. New gynaecology patients will be consented and randomised 1:1 to either the intervention arm, in which a digital tool is used for genetic cancer risk assessment, or usual care, in which the clinician performs genetic cancer risk assessment.
Background: Medical educational societies have emphasized the inclusion of marginalized populations, including the lesbian, gay, bisexual, transgender and queer (LGBTQ+) population, in educational curricula. Lack of inclusion can contribute to health inequality and mistreatment due to unconscious bias. Little didactic time is spent on the care of LGBTQ+ individuals in emergency medicine (EM) curricula.

Breast cancer risk assessment tools can identify those at elevated risk and allow for enhanced breast surveillance and chemoprevention, however such tools are underutilized. We aim to evaluate the use of routine breast cancer risk assessment in a gynecologic oncology clinic.
View Article and Find Full Text PDFBackground: Patients with a personal or family history of cancer may have elevated risk of developing future cancers, which often remains unrecognized due to lapses in screening. This pilot study assessed the usability and clinical outcomes of a cancer risk stratification tool in a gynecologic oncology clinic.
Methods: New gynecologic oncology patients were prompted to complete a commercially developed personal and family history-based risk stratification tool to assess eligibility for genetic testing using National Comprehensive Cancer Network criteria and estimated lifetime breast cancer risk using the Tyrer-Cuzick model.

Eula is a lytic microbacteriophage extracted from a soil sample collected in Statesville, NC, and isolated on Microbacterium foliorum NRRL B-24224. The Eula double-stranded DNA genome is 41,379 bp, with 69 predicted protein-coding genes and 1 tRNA. Based on gene content similarity, Eula was assigned to bacteriophage cluster EB.

Emergency medicine training programs frequently instruct this procedure via cadaver training, but cadaver cost and availability limit the opportunity for all trainees to perform the critical initial skin incision. Cadaver autografting is a novel way to simulate all steps of the procedure.

When exchange across the sediment-water interface (hyporheic exchange) is included in modeling, the mixing coefficient is often assumed to be constant with depth below the interface. Novel fiber-optic fluorometers have been developed and combined with a modified EROSIMESS system to quantify the vertical variation in mixing coefficient with depth below the sediment-water interface.

Patients are managed by surveillance with chemotherapy at relapse or adjuvant treatment up front. Late toxicities from chemotherapy are increasingly recognized.

Participants included 1590 5th, 7th, and 8th grade students who completed health surveys in 2011. Multivariate logistic regression was used to examine the association between health behaviors and ED use.

Both tumours were removed in their entirety at one visit to theatre and the patient remains well and in remission 18 months later.

Materials And Methods: This prospective study was approved by the Regional Ethics and Research and Development Committees. The perfusion CT protocol was incorporated in the staging CT after informed consent in 29 patients (14 men, 15 women; mean age, 70 years; age range, 55-94 years).
Objective: Colorectal cancer (CRC) has a substantial heritable component. Common genetic variation has been shown to contribute to CRC risk. A study was conducted in a large multi-population study to assess the feasibility of CRC risk prediction using common genetic variant data combined with other risk factors.

We present a single surgeon's short-term outcomes using the prone perineal extra-levator (elAPE) approach.

Recent genome-wide association studies have identified single-nucleotide polymorphisms at 16 genetic loci associated with colorectal cancer risk: rs6691170 (1q41), rs10936599 (3q26.2), rs16892766 (8q23.3), rs6983267 (8q24.

In clinical stage I non-seminomas, (NSGCT) histological vascular invasion (VI) is a prognostic factor for metastatic relapse. Using array comparative genomic hybridization, we have previously shown that the presence of VI is associated with gain of a region at 17q12, containing a cluster of genes encoding inflammatory cytokines.

Previous studies have examined the effect of using soybean varieties missing one or more of the 3 LOX isozymes on n-hexanal generation. A dynamic mathematical model of the soybean LOX pathway using ordinary differential equations was constructed using parameters estimated from existing data with the aim of predicting how n-hexanal generation could be reduced.

Methods: We investigated the relevance of 19 markers in 790 patients enrolled in a large randomised trial of 5-fluorouracil using immunohistochemistry and chromogenic in situ hybridisation.
Testicular germ cell tumors (TGCT) are the most frequent solid tumor to affect young adult males and are histologically divided into seminomas and nonseminomas (NS). NS comprise undifferentiated embryonal carcinoma (EC) and differentiated tumors with embryonic (teratoma) or extra-embryonic (choriocarcinoma, yolk sac tumor) features. In contrast to other subtypes, EC have uniform cellular morphology and lack normal cell infiltrates, ideal for nucleic acid profiling.

In a TMA, cylinders of tissue are cored out of formalin-fixed, paraffin-embedded tissue blocks and slotted in a regular grid pattern into a blank recipient paraffin wax block. The TMA block is then cut using a standard laboratory microtome.
