Effects of pulsatile intravenous follicle-stimulating hormone treatment on ovarian function in women with obesity.

Objective: To establish conditions for effective hypothalamic suppression in women with normal and high body mass index (BMI) and test the hypothesis that intravenous (IV) administration of pulsatile recombinant follicle-stimulating hormone (rFSH) can overcome the clinically evident dysfunctional pituitary-ovarian axis in women with obesity.

Design: Prospective interventional study.

Setting: Academic medical center.

Expression and T cell regulatory action of the PD-1 immune checkpoint in the ovary and fallopian tube.

Problem: Immune cell trafficking and surveillance within the ovary and fallopian tube are thought to impact fertility and also tumorigenesis in those organs. However, little is known of how native cells of the ovary and fallopian tube interact with resident immune cells. Interaction of the Programmed Cell Death Protein-1 (PD-1/PDCD-1/CD279) checkpoint with PD-L1 is associated with downregulated immune response.

Primary Myelin Oligodendrocyte Glycoprotein-Immunoglobulin G-associated Optic Neuritis Presenting after a Frozen Embryo Transfer.

Myelin oligodendrocyte glycoprotein (MOG)-immunoglobulin G-associated optic neuritis (ON) is a newly recognized antibody-mediated demyelinating disease of the central nervous system, resulting in acute visual loss and pain with eye movement. The effects of pregnancy on disease pathogenesis remain incompletely understood. Herein, we present a novel association between a frozen embryo transfer (FET) and the first manifestation of MOG-ON in a previously healthy patient with unexplained infertility.

The Drug Shortage Crisis in the United States: Impact on Cancer Pharmaceutical Safety.

Drug shortages pose a significant public health concern in the United States, and cancer drugs are among those most affected. Shortages present serious safety risks for patients and substantial burden on providers and the healthcare system. Multifaceted drivers of this complex problem include manufacturing disruptions, raw material shortages, regulatory issues, market dynamics, and limited financial incentives that reward quality and production of off-patent drugs.

Role of robotic surgery in treating fibroids and benign uterine mass.

Fibroid uterus can be managed medically, surgically, or through non-extirpative procedures, depending on the clinical situation. Myomectomy may be beneficial, especially to those desiring to preserve the uterus and/or fertility, with outcomes comparable to those of hysterectomy, with a laparoscopic approach being favored when feasible. For definitive therapy, hysterectomy can be pursued where the surgical approach should be individualized.

New Developments in Surgery for Endometriosis and Pelvic Pain.

Endometriosis is a common disease affecting reproductive age women. Pain is one of the most common symptoms associated with endometriosis. When medical therapy has failed or in known deeply infiltrating endometriosis, surgical management is warranted.

Laparoscopy vs. Robotic Surgery for Endometriosis (LAROSE): a multicenter, randomized, controlled trial.

Objective: To determine whether the use of the robot for surgical treatment of endometriosis is better than traditional laparoscopy in terms of operative length, perioperative parameters, and quality of life outcomes.

Design: Multicenter, randomized clinical trial.

Setting: University teaching hospitals.

Delays in Cancer Care Among Low-Income Minorities Despite Access.

Introduction: Narrowing the racial/ethnic and socioeconomic disparities in breast and cervical cancer requires an in-depth understanding of motivation for adherence to cancer screening and follow-up care. To inform patient-centered interventions, this study aimed to identify reasons why low-income women adhered to or delayed breast or cervical cancer screening, follow-up and treatment despite access to cancer care-related services.

Methods: Semistructured qualitative interviews were conducted among women with access to cancer care-related services receiving care at an academic cancer center, federally qualified health centers, or free clinics in the Chicago metropolitan area.

Economics of Malignant Gliomas: A Critical Review.

Purpose: Approximately 18,500 persons are diagnosed with malignant glioma in the United States annually. Few studies have investigated the comprehensive economic costs. We reviewed the literature to examine costs to patients with malignant glioma and their families, payers, and society.

Navigating veterans with an abnormal prostate cancer screening test: a quasi-experimental study.

Background: Prostate cancer disproportionately affects low-income and minority men. This study evaluates the impact of a patient navigation intervention on timeliness of diagnostic resolution and treatment initiation among veterans with an abnormal prostate cancer screen.

Methods: Participants were enrolled between 2006 and 2010.

Perceptions of patient-provider communication in breast and cervical cancer-related care: a qualitative study of low-income English- and Spanish-speaking women.

To explore patient perceptions of patient-provider communication in breast and cervical cancer-related care among low-income English- and Spanish-speaking women, we examined communication barriers and facilitators reported by patients receiving care at safety net clinics. Participants were interviewed in English or Spanish after receiving an abnormal breast or cervical cancer screening test or cancer diagnosis. Following an inductive approach, interviews were coded and analyzed by the language spoken with providers and patient-provider language concordance status.

Design of a prostate cancer patient navigation intervention for a Veterans Affairs hospital.

Background: Patient navigation programs have been launched nationwide in an attempt to reduce racial/ethnic and socio-demographic disparities in cancer care, but few have evaluated outcomes in the prostate cancer setting. The National Cancer Institute-funded Chicago Patient Navigation Research Program (C-PNRP) aims to implement and evaluate the efficacy of a patient navigation intervention for predominantly low-income minority patients with an abnormal prostate cancer screening test at a Veterans Affairs (VA) hospital in Chicago.

Methods/design: From 2006 through 2010, C-PNRP implemented a quasi-experimental intervention whereby trained social worker and lay health navigators worked with veterans with an abnormal prostate screen to proactively identify and resolve personal and systems barriers to care.

Costs and cost effectiveness of a health care provider-directed intervention to promote colorectal cancer screening.

Purpose: Colorectal cancer (CRC) screening remains underutilized in the United States. Prior studies reporting the cost effectiveness of randomized interventions to improve CRC screening have not been replicated in the setting of small physician practices. We recently conducted a randomized trial evaluating an academic detailing intervention in 264 small practices in geographically diverse New York City communities.

Accelerated approval of cancer drugs: improved access to therapeutic breakthroughs or early release of unsafe and ineffective drugs?

Purpose: Accelerated approval (AA) was initiated by the US Food and Drug Administration (FDA) to shorten development times of drugs for serious medical illnesses. Sponsors must confirm efficacy in postapproval trials. Confronted with several drugs that received AA on the basis of phase II trials and for which confirmatory trials were incomplete, FDA officials have encouraged sponsors to design AA applications on the basis of interim analyses of phase III trials.

Ticlopidine- and clopidogrel-associated thrombotic thrombocytopenic purpura (TTP): review of clinical, laboratory, epidemiological, and pharmacovigilance findings (1989-2008).

Thrombotic thrombocytopenic purpura (TTP) is a fulminant disease characterized by platelet aggregates, thrombocytopenia, renal insufficiency, neurologic changes, and mechanical injury to erythrocytes. Most idiopathic cases of TTP are characterized by a deficiency of ADAMTS13 (a disintegrin and metalloprotease, with thrombospondin-1-like domains) metalloprotease activity. Ironically, use of anti-platelet agents, the thienopyridine derivates clopidogrel and ticlopidine, is associated with drug induced TTP.
