A paradigm shift in understanding vulvovaginal melanoma as a distinct tumor type compared with cutaneous melanoma.

Objective: Our goal was to compare molecular and immune profiles of vulvovaginal melanoma (VVM) with cutaneous melanoma (CM) and explore the significance of immune checkpoint inhibitor (ICI) agents on survival.

Methods: Samples from VVM and CM tumors underwent comprehensive molecular and immune profiling. Treatment and survival data were extracted from insurance claims data and OS was calculated from time of ICI treatment to last contact.

The Genomic Landscape of Vulvar Squamous Cell Carcinoma.

Vulvar squamous cell cancer (VSC) accounts for 90% of vulvar cancers. Next-generation sequencing studies of VSC imply human papillomavirus (HPV) and p53 status play separate roles in carcinogenesis and prognosis. We sought to describe the genomic landscape and analyze the immunologic profiles of VSC with respect to HPV and p53 status.

Phosphodiesterase 10A (PDE10A) as a novel target to suppress β-catenin and RAS signaling in epithelial ovarian cancer.

A leading theory for ovarian carcinogenesis proposes that inflammation associated with incessant ovulation is a driver of oncogenesis. Consistent with this theory, nonsteroidal anti-inflammatory drugs (NSAIDs) exert promising chemopreventive activity for ovarian cancer. Unfortunately, toxicity is associated with long-term use of NSAIDs due to their cyclooxygenase (COX) inhibitory activity.

HER2 in Uterine Serous Carcinoma: Testing platforms and implications for targeted therapy.

Objective: HER2 is an important prognostic and therapeutic target in uterine serous carcinoma (USC). Optimal HER2 testing platforms have not been defined and guidelines for testing have changed over time. Our objective is to assess the concordance of HER2 positivity based on chromogenic in situ hybridization (CISH), immunohistochemistry (IHC), and next generation sequencing (NGS) and to determine the rate of downstream mutations that may affect response to HER2 directed therapy.

Molecular profiles of endometrial cancer tumors among Black patients.

Objectives: Disparate outcomes exist between Black and White patients with endometrial cancer (EC). One contributing factor is the disproportionately low representation of Black patients in clinical trials and in tumor molecular profiling studies. Our objective was to investigate molecular profiles of ECs in a cohort with a high proportion of tumors from Black patients.

Perivascular epithelioid cell tumor (PEComa) of the uterus: Challenges of pregnancy in determining prognosis and optimal treatment.

Background: Perivascular epithelioid cell tumor (PEComa) is a rare mesenchymal neoplasm that exhibits immunohistochemical evidence of smooth muscle and melanocytic differentiation. We report a case of uterine PEComa in a 21 year-old primigravida, presenting at time of c-section as a small subserosal lesion that expressed soft tan-brown tissue fragments. Microscopically the cells were epithelioid, staining positive for TFE3 and HMB45.

A novel proteomic-based screening method for ovarian cancer using cervicovaginal fluids: A window into the abdomen.

Objective: Our objective is to develop a site-specific proteomic-based screening test for ovarian cancer(OC) using the mucus of the cervix and vagina and evaluate a potential means for home testing.

Methods: Cervicovaginal fluid samples were obtained from ovarian cancer and normal control patients for LC-mass spectrometry(MS) proteomic evaluation. Statistical modeling determined the protein panel with the highest penetrance across ovarian cancer samples.

Platinum-resistant ovarian cancer: From drug resistance mechanisms to liquid biopsy-based biomarkers for disease management.

Resistance to platinum-based chemotherapy is a major clinical challenge in ovarian cancer, contributing to the high mortality-to-incidence ratio. Management of the platinum-resistant disease has been difficult due to diverse underlying molecular mechanisms. Over the past several years, research has revealed several novel molecular targets that are being explored as biomarkers for treatment planning and monitoring of response.

The Legal Consequences of Research Misconduct: False Investigators and Grant Proposals.

In a survey on research misconduct, roughly 20% of the respondents admitted that they have submitted federal grant proposals that include scholars as research participants even though those scholars were not expected to contribute to the research effort. This manuscript argues that adding such false investigators is illegal, violating multiple federal statutes including the False Statements Act (18 U.S.

Desvenlafaxine-associated hyperglycemia: A case report and literature review.

Desvenlafaxine is a potent selective serotonin and norepinephrine reuptake inhibitor used to treat depression and anxiety. Several antidepressants have been associated with drug-induced hyperglycemia, but currently there are no reports for desvenlafaxine. A case of suspected desvenlafaxine-induced hyperglycemia is presented involving a 59-year-old female with type 2 diabetes whose average blood glucose increased by 30 mg/dL for fasting blood glucose and 75 mg/dL for postprandial blood glucose 1 month after switching from venlafaxine to desvenlafaxine.

Maximizing efficiency in a high occupancy setting to utilize ultraviolet disinfection for isolation rooms.

Background: Ultraviolet (UV) disinfection decreases nosocomial disease rates in acute care settings; effective program implementation is poorly understood. We developed a program to UV-disinfect rooms following discharge of patients in transmission-based precautions (TBP) and assessed its effect on hospital-acquired infection (HAI) rates.

Methods: An isolation room housed a patient in any type of TBP.

The use of combination biological or small molecule therapy in inflammatory bowel disease: A retrospective cohort study.

Objective: There are limited data on using more than one biologic or small molecule drug combined to treat patients with inflammatory bowel disease. The aim of our study was to determine the effectiveness and safety of combination biologic use in inflammatory bowel disease.

Methods: We identified patients with Crohn's disease or ulcerative colitis who received treatment with a combination of two biologics or a biologic and a small molecule drug from 2015 to 2019 for persistent disease activity or concomitant rheumatological or dermatological disease.

Successful robotic surgery for primary resection of a vaginal leiomyosarcoma: A case report.

Primary vaginal leiomyosarcoma (LMS) is a rare entity with limited data on optimal treatment approach. Most previously reported cases utilize an open or transvaginal surgical approach for primary tumor resection. Minimally invasive surgery is an important tool in complex pelvic surgery and the limits of its utility continue to expand.

Health Care Provider Adherence to Surgical Guidelines for Risk-Reducing Salpingo-Oophorectomy.

Objective: To evaluate health care provider adherence to the surgical protocol endorsed by the National Comprehensive Cancer Network and the American College of Obstetricians and Gynecologists at the time of risk-reducing salpingo-oophorectomy and compare adherence between gynecologic oncologists and obstetrician-gynecologists (ob-gyns).

Methods: In this multicenter retrospective cohort study, women were included if they had a pathogenic BRCA mutation and underwent risk-reducing salpingo-oophorectomy between 2011 and 2017. Adherence was defined as completing all of the following: collection of washings, complete resection of the fallopian tube, and performing the Sectioning and Extensively Examining the Fimbriated End (SEE-FIM) pathologic protocol.

Reduced isolation room turnover time using Lean methodology.

Objective: To prevent environmental transmission of pathogens, hospital rooms housing patients on transmission-based precautions are cleaned extensively and disinfected with ultraviolet (UV) light. To do so consistently requires time and coordination, and these procedures must avoid patient flow delays and associated safety risks. We sought to improve room turnover efficiency to allow for UV disinfection.

Role of adjuvant radiation or re-excision for early stage vulvar squamous cell carcinoma with positive or close surgical margins.

Objectives: This study aims to evaluate whether re-excision or adjuvant radiation for stage I vulvar squamous cell carcinoma (SCC) with either a close or positive surgical margin improves recurrence-free survival.

Methods: Patients with pathologically confirmed FIGO stage I vulvar SCC who underwent primary surgical management between January 1, 1995 and September 30, 2017 and had positive or close (<8 mm) surgical margins were included. Kaplan-Meier curves were generated and compared using the log-rank test.

Authorship and citation manipulation in academic research.

Some scholars add authors to their research papers or grant proposals even when those individuals contribute nothing to the research effort. Some journal editors coerce authors to add citations that are not pertinent to their work and some authors pad their reference lists with superfluous citations. How prevalent are these types of manipulation, why do scholars stoop to such practices, and who among us is most susceptible to such ethical lapses? This study builds a framework around how intense competition for limited journal space and research funding can encourage manipulation and then uses that framework to develop hypotheses about who manipulates and why they do so.

Enhanced Thermoelectric Properties of Poly(3,4-ethylenedioxythiophene):poly(styrenesulfonate) by Binary Secondary Dopants.

Unlabelled: To simultaneously increase the electrical conductivity and Seebeck coefficient of poly(3,4-ethylenedioxythiophene):polystyrenesulfonate (

Pedot: PSS) was a challenge for realizing efficient organic thermoelectrics. In this study, for the first time, we report both increased electrical conductivities and Seebeck coefficients, hence, enhanced thermoelectric properties of

Pedot: PSS thin films by doped with binary secondary dopants, dimethyl sulfoxide (DMSO) and poly(ethylene oxide) (PEO). Without modifying film morphology, the molar ratios of PEDOT to PSS are tuned by PEO, resulting in increased proportions of PEDOT in the bipolaron states.

Transforming growth factor beta in bovine placentas.

Transforming growth factor beta s (TGF beta) are a family of multifunctional growth factors that are important embryonic morphogens. Because TGF beta s may regulate the development of epitheliochorial placentas, we investigated the location, expression, secretion, and effects of TGF beta s in bovine placentomes and cell cultures derived from chorionic and endometrial epithelia. Placentomes from early second-trimester pregnancies were examined by immunohistochemistry for TGF beta 1, TGF beta 2, and TGF beta 3, and for TGF beta expression in Northern slot-blots.

Plasma concentration profile of epidural alfentanil. Bolus followed by continuous infusion technique in the parturient: effect of epidural alfentanil and fentanyl on fetal heart rate.

Background And Objectives: A combined bolus and continuous epidural infusion technique of opioid and bupivacaine mixture has been described, although no pharmacokinetic data for this technique exists. The study documents the plasma concentration profile of epidural alfentanil in parturients using this technique, and evaluates the fetal heart rate tracing for associated changes following opioid administration.

Methods: Twenty-four subjects were randomized to receive epidural alfentanil 500 micrograms in 10 mL 0.

The addition of epinephrine to subarachnoid administered hyperbaric bupivacaine with fentanyl for cesarean delivery: the effect on onset time.
