A pragmatic randomized trial of a primary care antimicrobial stewardship intervention in Ontario, Canada.

Background: More than 90% of antibiotics are prescribed in primary care, but 50% may be unnecessary. Reducing unnecessary antibiotic overuse is needed to limit antimicrobial resistance. We conducted a pragmatic trial of a primary care provider-focused antimicrobial stewardship intervention to reduce antibiotic prescriptions in primary care.

Long-Term Psychosocial Functioning in Women with Bilateral Prophylactic Mastectomy: Does Preservation of the Nipple-Areolar Complex Make a Difference?

Introduction: Nipple-sparing prophylactic mastectomy (PM) is an option for women at high-risk for breast cancer, and may offer better cosmetic results than a skin-sparing PM where the nipple-areolar complex (NAC) is removed. However, there may be residual breast cancer risk due to the maintained NAC. It is unclear if sparing the NAC with PM impacts on psychosocial functioning, including cancer-related distress and body image after PM.

Homing receptor expression is deviated on CD56+ blood lymphocytes during pregnancy in Type 1 diabetic women.

Type 1 Diabetes Mellitus (T1DM) is characterized by an augmented pro-inflammatory immune state. This contributes to the increased risk for gestational complications observed in T1DM mothers. In normal pregnancies, critical immunological changes occur, including the massive recruitment of lymphocytes, particularly CD56bright NK cells, into early decidua basalis and a 2nd trimester shift towards Type 2 immunity.

Blocking of stromal cell-derived factor-1 reduces neoangiogenesis in human endometriosis lesions in a mouse model.

Problem: Endometriosis affects 5-10% of women and is characterized by the growth of endometrial tissue outside of the uterus. Establishing new blood supply is a fundamental requirement for endometriosis lesion growth. Endothelial progenitor cells (EPCs), recruited by stromal cell-derived factor-1 (SDF-1), contribute to neoangiogenesis in endometriotic lesions.

Animal models for anti-angiogenic therapy in endometriosis.

Endometriosis is a gynecological disease characterized by the growth of endometrium outside of the uterine cavity. It is often associated with dysmenorrhea, dyspareunia, pelvic pain and infertility. One of the key requirements for endometriotic lesions to survive is development of a blood supply to support their growth.

Thrombospondin-1 mimetic peptide ABT-898 affects neovascularization and survival of human endometriotic lesions in a mouse model.

Endometriosis is a common cause of pelvic pain and infertility in women, and a common indication for hysterectomy, yet the disease remains poorly diagnosed and ineffectively treated. Because endometriotic lesions require new blood supply for survival, inhibiting angiogenesis could provide a novel therapeutic strategy. ABT-898 mimics the antiangiogenic properties of thrombospondin-1, so we hypothesized that ABT-898 will prevent neovascularization of human endometriotic lesions and that ABT-898 treatment will not affect reproductive outcomes in a mouse model.

Morbidity and mortality after liver resection: results of the patient safety in surgery study.

Background: Liver resection is performed with increasing frequency. Nearly all of the published information on operative mortality and morbidity rates associated with liver resection is derived from studies that rely on retrospective data collection from single centers. The goal of this study is to use audited multiinstitutional data from the private sector of the Patient Safety in Surgery Study to characterize complications after liver resection and to identify variables that are associated with 30-day morbidity and mortality.
