RESUMO
INTRODUCTION AND HYPOTHESIS: Transgender men and transmasculine individuals report a variety of lower urinary tract symptoms (LUTS), but little is known about LUTS in this population. One of the obstacles is the lack of validated questionnaires. This study was aimed at validating the International Consultation on Incontinence Questionnaire-Lower Urinary Tract Symptoms (ICIQ-LUTS), which measures filling, voiding, and incontinence symptoms, in transmasculine individuals. METHODS: This is an observational validation study that included transmasculine individuals receiving care within a single tertiary care hospital system. Construct validity was assessed by comparing the ICIQ-LUTS with severity of LUTS as measured by the Urinary Distress Inventory-Short Form (UDI-6), and concurrent validity by the association between ICIQ-LUTS and the Patient Perception of Bladder Condition (PPBC). Discriminant validity was determined by comparing ICIQ-LUTS scores in those with and those without self-reported LUTS. Spearman correlation, t test, and Kruskal-Wallis test were used for data analysis. RESULTS: A total of 131 respondents were included in the analysis. Only two individuals (1.5%) reported prior vaginectomy and/or phalloplasty. Concurrent validity was demonstrated by a significant association between ICIQ-LUTS subscales and PPBC (filling p < 0.001, voiding p < 0.001, incontinence p < 0.001). Construct validity was demonstrated by a significant correlation between ICIQ-LUTS and UDI-6 (filling ρ = 0.76, p < 0.001; voiding ρ = 0.48, p < 0.001; incontinence ρ = 0.61, p < 0.001). For discriminant validity, those with at least one self-reported LUTS had significantly higher (worse) ICIQ-LUTS subscale scores than those without self-reported LUTS. CONCLUSIONS: The ICIQ-LUTS is valid for measurement of LUTS severity in transmasculine individuals. This will be an important tool to use in future research to learn more about LUTS in this population.
RESUMO
INTRODUCTION: Urinary incontinence (UI) among women is under-recognized in primary care setting. We hypothesized that UI is, therefore, more commonly diagnosed by specialists. Our aim was to determine the rate of UI diagnosis by provider and patient demographics, and whether these factors affect the likelihood of UI diagnosis. METHODS: Retrospective study using electronic medical records from 2010 to 2019. Ambulatory patient encounters by adult females were identified. Encounters with new diagnosis of UI (stress, urgency, mixed, or unspecified) were identified using ICD 9 and 10 codes. The following data were extracted: diagnosing provider specialty and sex, patient age, BMI, race, estimated household income, insurance coverage and type, and primary care provider (PCP). Rate of UI diagnosis was calculated using proportions. Univariable comparison and multivariable logistic regression were performed. RESULTS: 576,110 patient encounters were captured. 14,378 patient encounters had UI diagnosis (2.5%). UI population had the following characteristics: Mean age of 60.1 ± 15.5 years, 65.6% identified as white, 75.7% had a PCP, and 87.9% had insurance. UI diagnosis rate was < 1% for PCPs. Multivariable logistic regression showed that urogynecologists and female providers were more likely to diagnose UI; patient demographics associated with UI diagnosis included older age, elevated BMI, white race, commercial insurance, and having a PCP. Estimated household income did not have a significant effect. CONCLUSION: Diagnosis of UI is seldom made by PCPs. Race, insurance, and having a PCP may affect the likelihood of receiving UI diagnosis. Continued efforts to promote equity in recognizing UI may be warranted.

Nuclear factor erythroid-derived 2-like 2 (Nrf2) is a ubiquitously expressed transcription factor that is well known for its role in regulating the cellular redox pathway. Although there is mounting evidence suggesting a critical role for Nrf2 in hematopoietic stem cells and innate leukocytes, little is known about its involvement in T-cell biology. In this study, we identified a novel role for Nrf2 in regulating alloreactive T-cell function during allogeneic hematopoietic cell transplantation (allo-HCT). We observed increased expression and nuclear translocation of Nrf2 upon T-cell activation in vitro, especially in CD4+ donor T cells after allo-HCT. Allo-HCT recipients of Nrf2 -/- donor T cells had significantly less acute graft-versus-host disease (GVHD)-induced mortality, morbidity, and pathology. This reduction in GVHD was associated with the persistence of Helios+ donor regulatory T cells in the allograft, as well as defective upregulation of the gut-homing receptor LPAM-1 on alloreactive CD8+ T cells. Additionally, Nrf2 -/- donor CD8+ T cells demonstrated intact cytotoxicity against allogeneic target cells. Tumor-bearing allo-HCT recipients of Nrf2 -/- donor T cells had overall improved survival as a result of preserved graft-versus-tumor activity and reduced GVHD activity. Our findings characterized a previously unrecognized role for Nrf2 in T-cell function, as well as revealed a novel therapeutic target to improve the outcomes of allo-HCT.

PURPOSE: Retrospective cohort studies have shown a relationship between maternal serum interleukin-1ß (IL-1ß) and interleukin-1 receptor antagonist (IL-1Ra) levels and in vitro fertilization (IVF) cycle outcome. The objective of this investigation was to explore the correlation between serum IL-1ß and/or IL-1Ra levels obtained prospectively and IVF outcomes. METHODS: Sera from 205 women were collected just prior to initiation of their IVF cycle, at the time of human chorionic gonadotropin administration, day 24 of IVF cycle, day 28, and day 35. Sera were analyzed for IL-1ß and IL-1Ra using commercially available ELISA kits. Cycle outcomes were followed prospectively. Data were analyzed using Friedman analysis of variance by ranks and chi-square analysis. RESULTS: Among women with a viable pregnancy, IL-1ß serum levels increased over time for those that proceeded to deliver or had an ongoing pregnancy. There was no increase in serum levels for those with subsequent pregnancy loss. Of the women that had an embryo transfer, detectable IL-1ß levels at the start of the cycle were associated with successful IVF outcome (p = 0.027). Of women with a positive pregnancy test, undetectable IL-1ß at the start of the cycle were associated with subsequent pregnancy loss (p = 0.046). For all IL1-Ra serum analysis, there were no significant results. CONCLUSIONS: The increasing levels of IL-1ß over time are consistent with the known role of the IL-1 cytokine family in implantation and pregnancy. Additionally, we confirm in a prospective investigation the positive relationship between detectable serum IL-1ß at the start of IVF cycle and outcome.

OBJECTIVE: The number of patients who seek health information on the internet is increasing. Rates are particularly high among lesbian, gay, bisexual, transgender and queer (LGBTQ) individuals, due to health care barriers. The aim of this study was to evaluate the quality and inclusivity of web-based information pertaining to LGBTQ family building. METHODS: The first 100 US-based websites pertaining to LGBTQ family building were identified through a terminology-based internet search. After eliminating 45 websites, 55 websites were found to be eligible. The 2016 Website Information Reliability Evaluation Instrument (of the Office of Disease Prevention and Health Promotion, US Department of Health and Human Services) was used to analyse the quality of information on each website. Websites were analysed for inclusivity of important topics surrounding LGBTQ family building. RESULTS: A total of 46 websites (83.6%) belonged or were related to reproductive services and served as advertisements for their respective owners; nine websites (16.4%) belonged to third parties. No website met more than four of the six major reliability criteria, and 42 websites (76.4%) met only one or two of the six major reliability criteria. When inclusivity was considered, 29 websites (52.7%) mentioned options for transgender individuals and nine websites (16.4%) mentioned adoption. CONCLUSIONS: There is a lack of reliable web-based information for LGBTQ family building and a need for improvement in quality and scope. Improvements could lead to a shift in reproductive health care towards better inclusion of and catering to LGBTQ individuals.

T-cell deficiency related to disease, medical treatment, or aging represents a major clinical challenge and is associated with significant morbidity and mortality in cancer and bone marrow transplantation recipients. This study describes several innovative and clinically relevant strategies to manipulate thymic function based on an interventional radiology technique for intrathymic injection of cells or drugs. We show that intrathymic injection of multipotent hematopoietic stem/progenitor cells into irradiated syngeneic or allogeneic young or aged recipients resulted in efficient and long-lasting generation of functional donor T cells. Persistence of intrathymic donor cells was associated with intrathymic presence of cells resembling long-term hematopoietic stem cells, suggesting a self-renewal capacity of the intrathymically injected cells. Furthermore, our approach enabled the induction of long-term antigen-specific T-cell-mediated antitumor immunity following intrathymic injection of progenitor cells harboring a transgenic T-cell receptor gene. The intrathymic injection of interleukin-7 prior to irradiation conferred radioprotection. In addition, thymopoiesis of aged mice improved with a single intrathymic administration of low-dose keratinocyte growth factor, an effect that was sustained even in the setting of radiation-induced injury. Taken together, we established a preclinical framework for the development of novel clinical protocols to establish lifelong antigen-specific T-cell immunity.

OBJECTIVES: To determine whether catheterization rates after intradetrusor onabotulinumtoxinA injection for nonneurogenic overactive bladder and urgency incontinence differ between women with urgency urinary incontinence only and women with urgency-predominant mixed urinary incontinence. METHODS: This was a retrospective cohort study of patients that underwent intradetrusor onabotulinumtoxinA injection of 100 U for nonneurogenic urgency urinary incontinence. The primary outcome was the difference in catheterization rates between women with urgency urinary incontinence alone compared with women with urgency-predominant mixed urinary incontinence. Descriptive statistics and multivariate logistic regression analysis were performed. RESULTS: Of the 177 women included in the final analysis, 105 had urgency urinary incontinence and 72 had urgency-predominant mixed urinary incontinence. The overall catheterization rate after onabotulinumtoxinA injection was 11.3%, with significantly fewer women with mixed urinary incontinence requiring catheterization when compared with women with urgency urinary incontinence alone (4.2% vs 16.2%; P = 0.03), despite an older population (P = 0.02). Patient-reported improvement (P = 0.37) and decision to continue onabotulinumtoxinA treatments (P = 0.89) were similar between groups. Multivariate logistic regression analysis revealed that women with mixed urinary incontinence had significantly lower odds of requiring catheterization after onabotulinumtoxinA injections than women with urgency urinary incontinence alone (odds ratio, 0.16; 95% confidence interval, 0.04-0.67; P = 0.01). CONCLUSIONS: Findings suggest that the presence of symptomatic stress urinary incontinence is associated with lower rates of catheterization after intradetrusor onabotulinumtoxinA, but does not compromise efficacy of treatment for urgency-predominant mixed urinary incontinence.

OBJECTIVE: As medical students' interest in surgical fields wanes, we investigated the impact of a preclinical surgical exposure program on students' attitudes toward pursuing surgical careers. DESIGN: This is a prospective longitudinal study of PreOp, a preclinical rotation-based surgical exposure program for first-year medical students, from 2013 to 2017. Surveys assessed PreOp rotation quality, students' surgical interest, and students' self-reported preparedness for the surgical clerkship. Surgery clerkship grades were obtained as a measure of surgical competency and compared to class-wide peers. Match data was collected and compared to class-wide peers as well as historical norms. SETTING: NewYork-Presbyterian Hospital/Weill Cornell Medicine, New York, NY; tertiary care center. PARTICIPANTS: Fifty-four PreOp students from 2013 to 2017. RESULTS: Fifty-four PreOp participants were recruited. After completing the PreOp program, 66.7% of PreOp students reported being very likely to apply into a surgical field compared to 29.4% when they started medical school. Ultimately, 71.4% of PreOp students versus 21.7% of non-PreOp class-wide peers matched into surgical fields (p < 0.001). From the preceding 5 match years before PreOp implementation, 21.4% of all students matched into surgical fields compared to 25.6% of all students after PreOp was started (pâ¯=â¯0.26). In terms of preparedness, 75% of PreOp students reported feeling more prepared for the third-year surgery clerkship than their non-PreOp peers after the second year of medical school. PreOp students were significantly more likely than non-PreOp class-wide peers to receive honors in the surgery clerkship when controlling for cumulative clerkship GPA (pâ¯=â¯0.012, adjusted odds ratioâ¯=â¯5.5 [95% confidence interval 1.5-22.1]). CONCLUSIONS: Hands-on preclinical surgical exposure was associated with student-reported increased surgical interest that was maintained longitudinally and reflected in significantly increased surgical matches relative to non-PreOp class-wide peers. This study uniquely demonstrates that participation in PreOp was also associated with increased self-reported surgical preparedness and significantly higher surgery clerkship grades relative to overall academic performance.

Allogeneic hematopoietic stem cell transplantation (allo-HSCT) is a potentially curative therapy for hematological malignancies. However, graft-versus-host disease (GVHD) and relapse after allo-HSCT remain major impediments to the success of allo-HSCT. Chimeric antigen receptors (CARs) direct tumor cell recognition of adoptively transferred T cells. CD19 is an attractive CAR target, which is expressed in most B cell malignancies, as well as in healthy B cells. Clinical trials using autologous CD19-targeted T cells have shown remarkable promise in various B cell malignancies. However, the use of allogeneic CAR T cells poses a concern in that it may increase risk of the occurrence of GVHD, although this has not been reported in selected patients infused with donor-derived CD19 CAR T cells after allo-HSCT. To understand the mechanism whereby allogeneic CD19 CAR T cells may mediate anti-lymphoma activity without causing a significant increase in the incidence of GVHD, we studied donor-derived CD19 CAR T cells in allo-HSCT and lymphoma models in mice. We demonstrate that alloreactive T cells expressing CD28-costimulated CD19 CARs experience enhanced stimulation, resulting in the progressive loss of both their effector function and proliferative potential, clonal deletion, and significantly decreased occurrence of GVHD. Concurrently, the other CAR T cells that were present in bulk donor T cell populations retained their anti-lymphoma activity in accordance with the requirement that both the T cell receptor (TCR) and CAR be engaged to accelerate T cell exhaustion. In contrast, first-generation and 4-1BB-costimulated CAR T cells increased the occurrence of GVHD. These findings could explain the reduced risk of GVHD occurring with cumulative TCR and CAR signaling.

NF-κB plays a variety of roles in oncogenesis and immunity that may be beneficial for therapeutic targeting, but strategies to selectively inhibit NF-κB to exert antitumor activity have been elusive. Here, we describe IT-901, a bioactive naphthalenethiobarbiturate derivative that potently inhibits the NF-κB subunit c-Rel. IT-901 suppressed graft-versus-host disease while preserving graft-versus-lymphoma activity during allogeneic transplantation. Further preclinical assessment of IT-901 for the treatment of human B-cell lymphoma revealed antitumor properties in vitro and in vivo without restriction to NF-κB-dependent lymphoma. This nondiscriminatory, antilymphoma effect was attributed to modulation of the redox homeostasis in lymphoma cells resulting in oxidative stress. Moreover, NF-κB inhibition by IT-901 resulted in reduced stimulation of the oxidative stress response gene heme oxygenase-1, and we demonstrated that NF-κB inhibition exacerbated oxidative stress induction to inhibit growth of lymphoma cells. Notably, IT-901 did not elicit increased levels of reactive oxygen species in normal leukocytes, illustrating its cancer selective properties. Taken together, our results provide mechanistic insight and preclinical proof of concept for IT-901 as a novel therapeutic agent to treat human lymphoid tumors and ameliorate graft-versus-host disease.

Paradoxical to its importance for generating a diverse T cell repertoire, thymic function progressively declines throughout life. This process has been at least partially attributed to the effects of sex steroids, and their removal promotes enhanced thymopoiesis and recovery from immune injury. We show that one mechanism by which sex steroids influence thymopoiesis is through direct inhibition in cortical thymic epithelial cells (cTECs) of Delta-like 4 (Dll4), a Notch ligand crucial for the commitment and differentiation of T cell progenitors in a dose-dependent manner. Consistent with this, sex steroid ablation (SSA) led to increased expression of Dll4 and its downstream targets. Importantly, SSA induced by luteinizing hormone-releasing hormone (LHRH) receptor antagonism bypassed the surge in sex steroids caused by LHRH agonists, the gold standard for clinical ablation of sex steroids, thereby facilitating increased Dll4 expression and more rapid promotion of thymopoiesis. Collectively, these findings not only reveal a novel mechanism underlying improved thymic regeneration upon SSA but also offer an improved clinical strategy for successfully boosting immune function.
