Identifying topics of discussions in online health communities (OHC) is critical to various information extraction applications, but can be difficult because topics of OHC content are usually heterogeneous and domain-dependent. In this paper, we provide a multi-class schema, an annotated dataset, and supervised classifiers based on convolutional neural network (CNN) and other models for the task of classifying discussion topics. We apply the CNN classifier to the most popular breast cancer online community, and carry out cross-sectional and longitudinal analyses to show topic distributions and topic dynamics throughout members' participation...

BACKGROUND: Stomatitis is a class effect associated with the inhibition of mTOR and is associated with everolimus therapy for breast cancer. Topical steroids might reduce stomatitis incidence and severity, and the need for dose reductions and interruptions of everolimus. Anecdotal use of topical steroid oral prophylaxis has been reported in patients with breast cancer. We aimed to assess dexamethasone-based mouthwash for prevention of stomatitis in patients with breast cancer. METHODS: This US-based, multicentre, single-arm, phase 2 prevention study enrolled women aged 18 years and older with postmenopausal status who had histologically or cytologically confirmed metastatic hormone receptor-positive, HER2-negative breast cancer...

BACKGROUND: After treatment for breast cancer, most women receive an annual surveillance mammography to look for subsequent breast cancers. Supplemental breast MRI is sometimes used in addition to mammography despite the lack of clinical evidence for it. Breast imaging after cancer treatment is an emotionally charged experience, an important part of survivorship care, and a topic about which limited patient information exists. We assessed women's experiences and preferences about breast cancer surveillance imaging with the goal of determining where gaps in care and knowledge could be filled...

189 Background: Stomatitis is a frequent adverse event (AE) associated with mTOR inhibition. In BOLERO-2 patients (pts) receiving EVE/EXE, all grade (Gr) stomatitis was 67%; 33% had Gr ≥ 2 and 8% Gr 3. Median time to ≥ Gr 2 onset was 15.5 days; incidence of new stomatitis (Gr ≥ 2) plateaued at 6 wks. In a meta-analysis, 89% of first stomatitis events occurred within 8 wks. Topical steroids are used to treat aphthous ulcers; anecdotal use as prophylaxis has been reported. METHODS: Eligibility included PM women with HR+ MBC prescribed EVE/EXE...

Digital Breast Tomosynthesis (DBT) is rapidly replacing mammography as the standard of care in breast cancer screening and diagnosis. DBT is a form of computed tomography, in which a limited set of projection images are acquired over a small angular range and reconstructed into tomographic data. The angular range varies from 15° to 50° and the number of projections varies between 9 and 25 projections, as determined by the equipment manufacturer. It is equally valid to treat DBT as the digital analog of classical tomography - that is, linear tomography...

Rahul Dwivedi, Sambath Tiroumal
PURPOSE: Paclitaxel (Taxol) is a microtubule-stabilizing agent and belongs to the taxane group of chemotherapeutic drugs. It is used to treat numerous malignancies, such as breast and lung cancers. A rare side effect of this drug includes cystoid macular edema (CME), which is presumed to resolve after cessation of Paclitaxel. We present a case of topical Dorzolamide 2% (Trusopt) having a possible successful effect in the treatment of Paclitaxel-related nonresolving CME. By highlighting this rare ocular side effect of a common chemotherapeutic agent, which fails to resolve upon cessation of the drug alone, we suggest a possible treatment that may help other ophthalmologists in their management of similar cases...

Social support studies often focus on psychological outcomes for the support recipient and also presume potential support providers who will attempt to provide support in the first place. Therefore, the negative relational outcomes associated with not receiving emotional support when support is expected (nonsupport) are an understudied topic. Instances of nonsupport were compared to various emotional support messages on relational and psychological outcomes to understand how nonsupport compares against support messages of varying quality...

Biomarker-targeted surface-enhanced Raman scattering (SERS) nanoparticles (NPs) have been explored as a viable option for targeting and imaging multiple cell-surface protein biomarkers of cancer. While it has been demonstrated that this Raman-encoded molecular imaging (REMI) technology may potentially be used to guide tumor-resection procedures, the REMI strategy would benefit from further improvements in imaging speed. Previous implementations of REMI have utilized 1024 spectral channels (camera pixels) in a commercial spectroscopic CCD to detect the spectral signals from multiplexed SERS NPs, a strategy that enables accurate demultiplexing of the relative concentration of each NP "flavor" within a mixture...
