First-line vs second-line fulvestrant for hormone receptor-positive advanced breast cancer: A post-hoc analysis of the CONFIRM study.

Objectives: The double-blind, phase III CONFIRM study (NCT00099437) evaluated fulvestrant 500 mg vs fulvestrant 250 mg in postmenopausal women with hormone receptor-positive locally advanced/metastatic breast cancer (LA/MBC). This post-hoc analysis investigated the efficacy and safety of fulvestrant given either first-line or second-line for advanced disease.

Materials & Methods: Progression-free survival (PFS) and overall survival (OS) with fulvestrant 500 mg vs fulvestrant 250 mg was evaluated using unadjusted log-rank tests in patients treated in the first- (progression during or within 12 months after completing adjuvant endocrine therapy; n = 387) and second-line (following endocrine therapy for LA/MBC; n = 343) settings.

Deaf: A Concept Analysis From a Cultural Perspective Using the Wilson Method of Concept Analysis Development.

The purpose of this article is to provide an analysis of the concept Deaf to increase health care provider (HCP) understanding from a cultural perspective. Deaf signers, people with hearing loss who communicate primarily in American Sign Language (ASL), generally define the term Deaf as a cultural heritage. In the health care setting, the term deaf is most often defined as a pathological condition requiring medical intervention.

TITAN: phase III study of doxorubicin/cyclophosphamide followed by ixabepilone or paclitaxel in early-stage triple-negative breast cancer.

Purpose: Ixabepilone is a microtubule stabilizer with activity in taxane-refractory metastatic breast cancer and low susceptibility to taxane-resistance mechanisms including multidrug-resistant phenotypes and high β-III tubulin expression. Since these resistance mechanisms are common in triple-negative breast cancer (TNBC), ixabepilone may have particular advantages in this patient population. This study evaluated the substitution of ixabepilone for paclitaxel following doxorubicin/cyclophosphamide (AC) in the adjuvant treatment of early-stage TNBC.

Nurse practitioner perceptions of barriers and facilitators in providing health care for deaf American Sign Language users: A qualitative socio-ecological approach.

Background And Purpose: Nurse practitioners (NPs), as well as all healthcare clinicians, have a legal and ethical responsibility to provide health care for deaf American Sign Language (ASL) users equal to that of other patients, including effective communication, autonomy, and confidentiality. However, very little is known about the feasibility to provide equitable health care. The purpose of this study was to examine NP perceptions of barriers and facilitators in providing health care for deaf ASL users.

Over-expression of catalase in myeloid cells confers acute protection following myocardial infarction.

Cardiovascular disease is the leading cause of death in the United States and new treatment options are greatly needed. Oxidative stress is increased following myocardial infarction and levels of antioxidants decrease, causing imbalance that leads to dysfunction. Therapy involving catalase, the endogenous scavenger of hydrogen peroxide (H2O2), has been met with mixed results.
