Same-day discharge after robotic surgery for endometrial cancer.

To assess the safety of same-day discharge (SDD) following robotic-assisted endometrial cancer staging and identify risk factors for postoperative admission in a diverse population. A review of patients who underwent robotic-assisted endometrial cancer staging from April 1, 2017 to April 1, 2019 was performed. Patients were evaluated for SDD if they met the following criteria: tolerating oral intake, voiding spontaneously, ambulating, negative orthostatic vitals, postoperative hemoglobin ≤ 2 g/dL from baseline, pain controlled on oral medications, and desire to be discharged.

Endocannabinoid metabolism and transport as targets to regulate intraocular pressure.

Cannabinoids are part of an endogenous signaling system found throughout the body, including the eye. Hepler and Frank showed in the early 1970s that plant cannabinoids can lower intraocular pressure (IOP), an effect since shown to occur via cannabinoid CB1 and GPR18 receptors. Endocannabinoids are synthesized and metabolized enzymatically.

Evidence that cannabinoid CB1 receptors regulate intraocular pressure via two opposing mechanisms.

The cannabinoid signaling system regulates intraocular pressure (IOP) in the mouse via a complex system that includes three receptors: CB1, GPR18 and GPR119. In each case, activating the receptor lowers IOP, but CB1 receptors are found both at sites of aqueous humor inflow and outflow. As such, knockout mice for any of these receptors would be expected to have higher-than average, or at least unchanged, intraocular pressure.

Evidence for a GPR18 Role in Chemotaxis, Proliferation, and the Course of Wound Closure in the Cornea.

Purpose: We previously showed that cannabinoid-related GPR18 receptors are present in the murine corneal epithelium, but their function remains unknown. The related CB1 receptors regulate corneal healing, possibly via chemotaxis. We therefore examined a potential role for GPR18 in corneal epithelial chemotaxis and wound healing.

Cannabinoid CB2R receptors are upregulated with corneal injury and regulate the course of corneal wound healing.

CB2R receptors have demonstrated beneficial effects in wound healing in several models. We therefore investigated a potential role of CB2R receptors in corneal wound healing. We examined the functional contribution of CB2R receptors to the course of wound closure in an in vivo murine model.

Δ9-Tetrahydrocannabinol and Cannabidiol Differentially Regulate Intraocular Pressure.

Purpose: It has been known for nearly 50 years that cannabis and the psychoactive constituent Δ9-tetrahydrocannabinol (THC) reduce intraocular pressure (IOP). Elevated IOP remains the chief hallmark and therapeutic target for glaucoma, a major cause of blindness. THC likely acts via one of the known cannabinoid-related receptors (CB1, CB2, GPR18, GPR119, GPR55) but this has never been determined explicitly.

Synthesis and evaluation of potent and selective MGL inhibitors as a glaucoma treatment.

Monoacylglycerol lipase (MGL) inhibition provides a potential treatment approach to glaucoma through the regulation of ocular 2-arachidonoylglycerol (2-AG) levels and the activation of CB1 receptors. Herein, we report the discovery of new series of carbamates as highly potent and selective MGL inhibitors. The new inhibitors showed potent nanomolar inhibitory activity against recombinant human and purified rat MGL, were selective (>1000-fold) against serine hydrolases FAAH and ABHD6 and lacked any affinity for the cannabinoid receptors CB1 and CB2.

Revisiting cannabinoid receptor 2 expression and function in murine retina.

The cannabinoid receptor CB2 plays a significant role in the regulation of immune function whereas neuronal expression remains a subject of contention. Multiple studies have described CB2 in retina and a recent study showed that CB2 deletion altered retinal visual processing. We revisited CB2 expression using immunohistochemistry and a recently developed CB2-eGFP reporter mouse.

High Rates of High-Grade Cervical Dysplasia in High-Risk Young Women With Low-Grade Cervical Cytology.

Objective: The aim of the study was to determine rates of cervical intraepithelial neoplasia (CIN) 2 or greater in high-risk, racially diverse, young women with low-grade cytology.

Materials And Methods: After institutional review board approval, a cross-sectional study of 21- to 24-year-old women with low-grade cytology (atypical squamous cells of undetermined significance, high-risk human papillomavirus+, low-grade squamous intraepithelial lesion, or human papillomavirus+ only) managed with colposcopy at our university-based clinic between May 2011 and April 2013 were identified. Demographics and pathologic data were collected including age, race, parity, smoking status, screening history, and histology.

Does Obesity Affect Pathologic Agreement of Initial and Final Tumor Grade of Disease in Endometrial Cancer Patients?

Objectives: The objectives of this study were to compare preoperative and postoperative tumor grade to determine if surgical staging decisions for endometrial cancer based on preoperative biopsy are feasible and whether obesity affects the agreement.

Methods: A retrospective cohort study of women with endometrial cancer between January 2010 and December 2011 was performed. Demographics, stage of final pathology, biopsy method, preoperative and postoperative tissue grade, and histology were abstracted and stratified by patient body mass index (obese ≥30 kg/m and nonobese <30 kg/m).

Evidence for a GPR18 Role in Diurnal Regulation of Intraocular Pressure.

Purpose: The diurnal cycling of intraocular pressure (IOP) was first described in humans more than a century ago. This cycling is preserved in other species. The physiologic underpinning of this diurnal variation in IOP remains a mystery, even though elevated pressure is indicated in most forms of glaucoma, a common cause of blindness.

Harnessing the Endocannabinoid 2-Arachidonoylglycerol to Lower Intraocular Pressure in a Murine Model.

Purpose: Cannabinoids, such as Δ9-THC, act through an endogenous signaling system in the vertebrate eye that reduces IOP via CB1 receptors. Endogenous cannabinoid (eCB) ligand, 2-arachidonoyl glycerol (2-AG), likewise activates CB1 and is metabolized by monoacylglycerol lipase (MAGL). We investigated ocular 2-AG and its regulation by MAGL and the therapeutic potential of harnessing eCBs to lower IOP.

Does a standardized preoperative algorithm of clinical data improve outcomes in patients with ovarian cancer? A quality improvement project.

Objective: To evaluate the potential impact of a standardized preoperative algorithm on outcomes of patients with suspected ovarian cancer.

Methods: From January 1 to December 31, 2013, patients with suspected ovarian cancer were triaged to primary debulking surgery or neoadjuvant chemotherapy/interval debulking surgery (NACT/IDS) based on a comprehensive review of preoperative clinical data as part of a quality improvement project. Demographics, surgical, and postoperative data were collected.

Diabetes mellitus and ovarian cancer: more complex than just increasing risk.

Objective: Diabetes mellitus (DM) is a risk factor for endometrial cancer and is associated with poorer outcomes in breast and colon cancers. This association is less clear in epithelial ovarian cancer (EOC). We sought to examine the effect of DM on progression-free (PFS) and overall survival (OS) in women with EOC.
