Sexual and gender minority cultural humility training for oncology settings: An example of iterative adaptation and implementation.

Background: Multiple national organizations recommend that cancer care providers and oncology practices be responsive to the needs of sexual and gender minority (SGM) patients. Oncology practices have attempted to incorporate this recommendation through SGM-focused cultural humility training interventions. It is unclear how best to adapt and implement such training across practices.

Radiation-induced inferior brachial plexopathy after stereotactic body radiotherapy: Pooled analyses of risks.

Introduction: Radiation-induced brachial plexopathy (RIBP), resulting in symptomatic motor or sensory deficits of the upper extremity, is a risk after exposure of the brachial plexus to therapeutic doses of radiation. We sought to model dosimetric factors associated with risks of RIBP after stereotactic body radiotherapy (SBRT).

Methods: From a prior systematic review, 4 studies were identified that included individual patient data amenable to normal tissue complication probability (NTCP) modelling after SBRT for apical lung tumors.

Hypofractionated Stereotactic Radiation Therapy Dosimetric Tolerances for the Inferior Aspect of the Brachial Plexus: A Systematic Review.

We sought to systematically review and summarize dosimetric factors associated with radiation-induced brachial plexopathy (RIBP) after stereotactic body radiation therapy (SBRT) or hypofractionated image guided radiation therapy (HIGRT). From published studies identified from searches of PubMed and Embase databases, data quantifying risks of RIBP after 1- to 10-fraction SBRT/HIGRT were extracted and summarized. Published studies have reported <10% risks of RIBP with maximum doses (D) to the inferior aspect of the brachial plexus of 32 Gy in 5 fractions and 25 Gy in 3 fractions.

Patient Perceptions of Sexual Orientation and Gender Identity Data Collection in an Outpatient Radiation Oncology Setting.

Purpose: Sexual and gender minority patients with cancer experience significant health disparities requiring tailored care. Collecting sexual orientation and gender identity (SOGI) data in the electronic medical record (EMR) could allow care to be tailored and is in line with radiation oncology's mission to better serve diverse patients. This article describes a systematic method for collecting SOGI data for all patients starting radiation treatment in a department of radiation oncology (DRO).

Risk of adverse pathological features for intermediate risk prostate cancer: Clinical implications for definitive radiation therapy.

Background: Intermediate risk prostate cancer represents a largely heterogeneous group with diverse disease extent. We sought to establish rates of adverse pathological features important for radiation planning by analyzing surgical specimens from men with intermediate risk prostate cancer who underwent immediate radical prostatectomy, and to define clinical pathologic features that may predict adverse outcomes.

Materials And Methods: A total of 1552 men diagnosed with intermediate risk prostate cancer who underwent immediate radical prostatectomy between 1/1/2005 and 12/31/2015 were reviewed.

Survival of Patients With Second Primary Hodgkin Lymphoma.

Introduction: The increased risk for second malignancies after Hodgkin lymphoma (HL) diagnosis is well known. However, to our knowledge, no study has investigated the outcomes of patients diagnosed with HL after an antecedent malignancy (HL-2). We aimed to investigate overall survival (OS), disease-specific survival (DSS), and correlates of survival in HL-2 using the Surveillance, Epidemiology and End Results (SEER) database.

Drug Counselors' Attitudes Toward Nonpharmacologic Treatments for Chronic Pain.

Objectives: To examine methadone counselors' attitudes toward individual and group-based nonpharmacologic treatments for chronic pain.

Methods: Thirty methadone drug counselors were interviewed about their attitudes toward pain interventions and completed a survey on the perceived efficacy of and willingness to refer patients to nonpharmacologic pain treatments.

Results: Counselors reported favorable attitudes toward interventions commonly found in interdisciplinary pain management, particularly, conventional psychological approaches.

A pilot trial of a videogame-based exercise program for methadone maintained patients.

Few studies have examined exercise as a substance use disorder treatment. This pilot study investigated the feasibility and acceptability of an exercise intervention comprising the Wii Fit Plus™ and of a time-and-attention sedentary control comprising Wii™ videogames. We also explored their impact on physical activity levels, substance use, and psychological wellness.

Slow conformational changes in MutS and DNA direct ordered transitions between mismatch search, recognition and signaling of DNA repair.

MutS functions in mismatch repair (MMR) to scan DNA for errors, identify a target site and trigger subsequent events in the pathway leading to error removal and DNA re-synthesis. These actions, enabled by the ATPase activity of MutS, are now beginning to be analyzed from the perspective of the protein itself. This study provides the first ensemble transient kinetic data on MutS conformational dynamics as it works with DNA and ATP in MMR.

A new system for comparative functional genomics of Saccharomyces yeasts.

Whole-genome sequencing, particularly in fungi, has progressed at a tremendous rate. More difficult, however, is experimental testing of the inferences about gene function that can be drawn from comparative sequence analysis alone. We present a genome-wide functional characterization of a sequenced but experimentally understudied budding yeast, Saccharomyces bayanus var.

α-Ketoglutarate coordinates carbon and nitrogen utilization via enzyme I inhibition.

Microbes survive in a variety of nutrient environments by modulating their intracellular metabolism. Balanced growth requires coordinated uptake of carbon and nitrogen, the primary substrates for biomass production. Yet the mechanisms that balance carbon and nitrogen uptake are poorly understood.

Selectivity and potency of the retroprogesterone dydrogesterone in vitro.

Dydrogesterone is widely used for menstrual disorders, endometriosis, threatened and habitual abortion and postmenopausal hormone replacement therapy. Although progestins have a promiscuous nature, dydrogesterone does not have clinically relevant androgenic, estrogenic, glucocorticoid or mineralocorticoid activities. To date, systematic biochemical characterization of this progestin and its active main metabolite, 20α-dihydrodydrogesterone, has not been performed in comparison to progesterone.

Application of stopped-flow kinetics methods to investigate the mechanism of action of a DNA repair protein.

Transient kinetic analysis is indispensable for understanding the workings of biological macromolecules, since this approach yields mechanistic information including active site concentrations and intrinsic rate constants that govern macromolecular function. In case of enzymes, for example, transient or pre-steady state measurements identify and characterize individual events in the reaction pathway, whereas steady state measurements only yield overall catalytic efficiency and specificity. Individual events such as protein-protein or protein-ligand interactions and rate-limiting conformational changes often occur in the millisecond timescale, and can be measured directly by stopped-flow and chemical-quench flow methods.

Metabolomics-driven quantitative analysis of ammonia assimilation in E. coli.

Despite extensive study of individual enzymes and their organization into pathways, the means by which enzyme networks control metabolite concentrations and fluxes in cells remains incompletely understood. Here, we examine the integrated regulation of central nitrogen metabolism in Escherichia coli through metabolomics and ordinary-differential-equation-based modeling. Metabolome changes triggered by modulating extracellular ammonium centered around two key intermediates in nitrogen assimilation, alpha-ketoglutarate and glutamine.

Kappa opioid receptor screen with the Tango beta-arrestin recruitment technology and characterization of hits with second-messenger assays.

Assays for high-throughput screening of G-protein-coupled receptors (GPCRs) have typically revolved around receptor binding, guanine nucleotide binding, and second-messenger assays measuring intracellular cAMP and calcium levels. New assay development has been directed toward G-protein-independent signaling pathways, including protein redistribution in response to activated receptors. beta-arrestin recruitment to agonist-stimulated GPCRs is the basis for the Transfluor, PathHunter, and Tango GPCR screening platforms.
