RESUMEN

BACKGROUND: Sexual health is understudied and underreported in patients with lung cancer, and most data precede the approval of widely used targeted therapies and immune checkpoint inhibitors. The authors sought to evaluate the prevalence of sexual dysfunction in women with lung cancer in our current clinical environment. METHODS: This cross-sectional survey study was administered online to 249 women via the GO2 for Lung Cancer (GO2) Registry, using the Patient-Reported Outcomes Measurement Information System Sexual Function and Satisfaction Measures questionnaire. Participants were recruited between June 2020 to June 2021. Eligibility criteria included age >18 years, self-identifying as a woman, fluency in English, and a lung cancer diagnosis within 10 years. RESULTS: Most (67%) had stage IV lung cancer and 47% were receiving targeted therapy; 66% were undergoing active treatment. Despite 54% of participants reporting "recent" sexual activity, most (77%) indicated having little to no interest in sexual activity and 48% reported recent minimal satisfaction with their sex life. The most common reasons negatively affecting participants' satisfaction with their sex life included fatigue (40%) and feeling sad/unhappy (28%). Common reasons for lack of recent sexual activity included lack of interest (68%) and vaginal dryness or pain (30%). Compared to pre-diagnosis, women were significantly less likely to have recent interest in sexual activity. In multivariable logistic-regression, vaginal dryness showed a significant negative association with recent interest in sexual activity. CONCLUSIONS: Sexual dysfunction is prevalent in women with lung cancer. Sexual health should be integrated into routine care for patients with lung cancer.

RESUMEN

INTRODUCTION: The primary objective of this study was to determine whether workplace culture in academic oncology differed by gender, during the COVID-19 pandemic. MATERIALS AND METHODS: We used the Culture Conducive to Women's Academic Success (CCWAS), a validated survey tool, to investigate the academic climate at an NCI-designated Cancer Center. We adapted the CCWAS to be applicable to people of all genders. The full membership of the Cancer Center was surveyed (total faculty = 429). The questions in each of 4 CCWAS domains (equal access to opportunities, work-life balance, freedom from gender bias, and leadership support) were scored using a 5-point Likert scale. Median score and interquartile ranges for each domain were calculated. RESULTS: A total of 168 respondents (men = 58, women = 106, n = 4 not disclosed) submitted survey responses. The response rate was 39% overall and 70% among women faculty. We found significant differences in perceptions of workplace culture by gender, both in responses to individual questions and in the overall score in the following domains: equal access to opportunities, work-life balance, and leader support, and in the total score for the CCWAS. CONCLUSIONS: Our survey is the first of its kind completed during the COVID-19 pandemic at an NCI-designated Cancer Center, in which myriad factors contributed to burnout and workplace challenges. These results point to specific issues that detract from the success of women pursuing careers in academic oncology. Identifying these issues can be used to design and implement solutions to improve workforce culture, mitigate gender bias, and retain faculty.

RESUMEN

Equity, diversity, and inclusion (EDI) are essential for healthcare organizations since they allow for the development of programs and initiatives that bring together diverse perspectives and knowledge. Global multidisciplinary organizations, such as the Multinational Association for Supportive Care in Cancer (MASCC), need to understand the perspective of their members regarding EDI to identify opportunities to enhance diversity and inclusiveness and to better meet the needs of members from different backgrounds and resources. The MASCC Health Disparities Committee designed a survey to identify issues related to disparities faced by MASCC members when providing supportive care to patients with cancer and to examine the EDI landscape within the organization. Here, we report results related to EDI initiatives within the organization. Two-hundred and eighteen MASCC members responded to the survey (response rate 10.2%). The results indicated that respondents were generally satisfied with how MASCC manages leadership, membership, and organization-related EDI issues. Opportunities for improvement noted by respondents included developing strategies to foster a more diverse membership, improving communication regarding diversity in the organization, and increasing EDI content in educational sessions and publications. The results of this survey represent the first attempt at understanding how to improve EDI within MASCC and will be utilized to guide further initiatives and programs.

RESUMEN

Providing cost-effective, comprehensive survivorship care remains a significant challenge. Breast cancer survivors (BCS) who have limited income and are from marginalized racial and ethnic groups experience a worse quality of life and report higher distress. Thus, innovative care models are required to address the needs of BCS in low resource settings. Group medical visits (GMV), utilized in chronic disease management, are an excellent model for education and building skills. This single-arm intervention study was conducted at a public hospital in California. GMVs consisted of five 2-h weekly sessions focused on survivorship care planning, side effects of treatment and prevention, emotional health, sexual health, physical activity, and diet. The patient navigators recruited three consecutive GMV groups of six English-speaking BCS (N = 17). A multidisciplinary team delivered GMVs, and a patient navigator facilitated all the sessions. We used attendance rates, pre- and post-surveys, and debriefing interviews to assess the feasibility and acceptability of the intervention. We enrolled 18 BCS. One participant dropped out before the intervention started, 17 BCS consistently attended and actively participated in the GMV, and 76% (13) attended all planned sessions. Participants rated GMVs in the post-survey and shared their support for GMVs in debriefing interviews. The BCS who completed the post-survey reported that GMVs increased their awareness, confidence, and knowledge of survivorship care. GMVs were explicitly designed to address unmet needs for services necessary for survivorship care but not readily available in safety net settings. Our pilot data suggest that patient-navigator-facilitated GMVs are a feasible and acceptable model for integrating survivorship care in public hospitals.

RESUMEN

Like many other aspects of hematology-oncology training, medical education experienced rapid changes throughout the COVID-19 pandemic that continue until today. We discuss some of the most transformative areas within medical education, including, but not limited to, educational philosophy; use of virtual resources; inter-institutional connections, shifts in clinical training; changes in recruitment practice; and attention to equity and diversity. Moreover, we add our own experiences to complement the limited literature addressing these topics. We conclude by highlighting some of the benefits of this unprecedented transformation in democratizing medical education that we hope endure beyond the pandemic.

RESUMEN

COVID-19 has been devastating for patients with cancer. In this commentary, we chronicle the pandemic's downstream impacts on United States hematology/oncology trainees in terms of professional development and career advancement. These include loss of access to clinical electives and protocol workshops, delays in research approval and execution, mentor shortages due to academic burnout, and obstacles with career transitions (most notably the post-fellowship job search). While certain silver linings from the pandemic have undoubtedly emerged, continued progress against COVID-19 will be essential to fully overcome the professional challenges it has created for the future hematology/oncology workforce.

RESUMEN

BACKGROUND: Lung cancer screening (LCS) is recommended for individuals at high risk due to age and smoking history after a shared decision-making conversation. However, little is known about best strategies for incorporating shared decision-making, especially in a busy primary care setting. OBJECTIVE: To develop a novel tool, Lung Cancer Assessment of Risk and Education (LungCARE) to guide LCS decisions among eligible primary care patients. DESIGN: Pilot cluster randomized controlled trial of LungCARE versus usual care. PARTICIPANTS: Patients of providers in a university primary care clinic, who met criteria for LCS. INTERVENTION: Providers were randomized to LungCARE intervention or control. LungCARE participants completed a computer tablet-based video assessment of lung cancer educational needs in the waiting room prior to a primary care visit. Patient and provider both received a summary handout of patient concerns and responses. MAIN MEASURES: All eligible patients completed baseline interviews by telephone. One week after the index visit, participants completed a follow-up telephone survey that assessed patient-physician discussion of LCS, referral to and scheduling of LCS, as well as LCS knowledge and acceptability of LungCARE. Two months after index visit, we reviewed patients' electronic health records (EHRs) for evidence of a shared decision-making conversation and referral to and receipt of LCS. KEY RESULTS: A total of 66 participants completed baseline and follow-up visits (34: LungCARE; 32: usual care). Mean age was 65.9 (± 6.0). Based on EHR review, compared to usual care, LungCARE participants were more likely to have discussed LCS with their physicians (56% vs 25%; p = 0.04) and to be referred to LCS (44% vs 13%; p < 0.02). Intervention participants were also more likely to complete LCS (32% vs 13%; p < 0.01) and had higher knowledge scores (mean score 6.5 (± 1.7) vs 5.5 (± 1.4; p < 0.01). CONCLUSIONS: LungCARE increased discussion, referral, and completion of LCS and improved LCS knowledge. CLINICAL TRIAL REGISTRATION: NCT03862001.

RESUMEN

INTRODUCTION: To contribute to the reduction and elimination of cancer-related local and global health disparities, interventions must be culturally adapted to reach diverse cultural groups and demonstrate success in improving clinical and psychosocial outcomes. We provide step-by-step information on the conceptual and methodological challenges involved in culturally adapting interventions and provide guidelines, suggestions, tools, and concrete steps for implementing the process. METHODS: This article provides information, guidelines, suggestions, tools, and concrete steps, based on three rigorous models of cultural adaptations, for implementing this process, followed with examples from the field, to illustrate the conceptual and methodological challenges involved in culturally adapting interventions. CONCLUSION: Our systematic step-by-step approach recommends (1) the guidance of well-established research models; (2) use of multiple data sources and input from various stakeholders (i.e., from patients and providers); (3) qualitative and quantitative data usage and integration; (4) a steering committee with multiple perspectives, stakeholders assessments, and qualitative analyses; (5) consensus meetings; and (6) diverse representation on the steering committee and/or research team.

RESUMEN

We previously demonstrated that treatment with BemA (bempedoic acid), an inhibitor of ATP citrate lyase, significantly reduces fatty liver in a model of liver steatosis (HFHFr-female Sprague-Dawley rat fed a high-fat high-fructose diet). Since the hepatic production of the gasotransmitter H2S is impaired in liver disorders, we were interested in determining if the production of H2S was altered in our HFHFr model and whether the administration of BemA reversed these changes. We used stored liver samples from a previous study to determine the total and enzymatic H2S production, as well as the expression of CBS (cystathionine ß-synthase), CSE (cystathionine γ-lyase), and 3MST (3-mercaptopiruvate sulfurtransferase), and the expression/activity of FXR (farnesoid X receptor), a transcription factor involved in regulating CSE expression. Our data show that the HFHFr diet reduces the total and enzymatic production of liver H2S, mainly by decreasing the expression of CBS and CSE. Furthermore, BemA treatment restored H2S production, increasing the expression of CBS and CSE, providing evidence for the involvement of FXR transcriptional activity and the mTORC1 (mammalian target of rapamycin1)/S6K1 (ribosomal protein S6 kinase beta-1)/PGC1α (peroxisome proliferator receptor gamma coactivator1α) pathway.

RESUMEN

BACKGROUND: The proportion of women in the field of hematology and oncology (H&O) has increased over recent decades, but the representation of women in leadership positions remains poor. In an effort to close the gender gap in academia, it is important to report on such inequities in hopes to close these gaps and improve career development. MATERIALS AND METHODS: We conducted a retrospective, observational study of published award recipients from 1994 to 2019 from the seven major H&O societies in the world. Gender was determined based on publicly available data. The χ2 and Cochran-Armitage tests were used for data analysis. RESULTS: Of the 1,642 awardees over the past 26 years, 915 met inclusion criteria. Award recipients were overwhelmingly men (77.9%) and non-Hispanic White (84.7%). Women awardees received 30.3% of the humanistic and education-related awards, whereas only receiving 16.0% of basic science awards (p < .01). Women represent 35.6% of all hematologists and oncologists but only received 24.0% of awards given to these physicians (p = .004). Black, Hispanic, and Asian awardees represented 3.7%, 3.3%, and 6.8% of the total awardees, respectively. CONCLUSION: From 1994 to 2019, women were less likely to receive recognition awards from the seven major H&O societies studied compared with men. We also observed a considerably low proportion of minority awardees across all oncology subspecialties. Further studies examining how selection criteria favor either gender would be warranted in order to achieve equal representation in academic awards. IMPLICATIONS FOR PRACTICE: In this study, women and minority groups were found to be underrepresented amongst award recipients. Significant disparities were seen in disciplines that have been historically male predominant, such as basic sciences. As awards on an international level enhance academic resumes and assist with career advancement, it is important that awards are being given in an equitable manner. First steps to promote diversity and inclusion in academic medicine is reporting of gender and racial disparities in various areas of academia.

RESUMEN

One of the most important threats to global human health is the increasing incidences of metabolic pathologies (including obesity, type 2 diabetes and non-alcoholic fatty liver disease), which is paralleled by increasing consumptions of hypercaloric diets enriched in simple sugars. The challenge is to identify the metabolic pathways affected by the excessive consumption of these dietary components when they are consumed in excess, to unravel the molecular mechanisms leading to metabolic pathologies and identify novel therapeutic targets to manage them. Mechanistic (mammalian) target of rapamycin (mTOR) has emerged as one of the key molecular nodes that integrate extracellular signals, such as energy status and nutrient availability, to trigger cell responses that could lead to the above-mentioned diseases through the regulation of lipid and glucose metabolism. By activating mTOR signalling, excessive consumption of simple sugars (such as fructose and glucose), could modulate hepatic gluconeogenesis, lipogenesis and fatty acid uptake and catabolism and thus lipid deposition in the liver. In the present review we will discuss some of the most recent studies showing the central role of mTOR in the metabolic effects of excessive simple sugar consumption.

RESUMEN

BACKGROUND: To assess the safety and efficacy of the Instinct clip in the acute endoscopic treatment of upper gastrointestinal bleeding (UGIB). MATERIALS AND METHODS: This is the first large series reporting this clip in achieving hemostasis. A retrospective descriptive chart review was performed on patients presenting with recent overt GI bleeding treated with endoclip therapy at Mount Sinai Beth Israel Medical Center between May 2013 and January 2016. Results are expressed in absolute numbers, percentages, and trends. RESULTS: In total, 178 consecutive patients with UGIB were included. Source of bleeding was identified as duodenal ulcer (29.2%), gastric ulcer (22.5%), gastro-esophageal junction tear (8.4%), anastomosis (5.6%), erosive gastropathy (5.6%), Dieulafoy (5.1%), gastric polyp (4.5%), postendoscopic procedure (3.9%), angioectasia (3.4%), esophageal ulcer (2.8%), benign duodenal mass (2.8%), peg tube site (2.3%), gastric neoplasm (1.7%), esophagitis (1.1%), and small bowel ulcer (1.1%). Lesions demonstrated active bleeding in 47.5% (11.3% spurting and 36.2% oozing) and nonbleeding lesions in 52.5% (25.0% visible vessel, 11.9% hematin in ulcer base, 10.0% adherent clot, 5.6% flat spot). Initial hemostasis was achieved in 96.6%. Additional methods were used in 24.1% (argon plasma coagulation and epinephrine injection in 21.3%, surgery in 0.6%, and interventional radiology in 2.2%). There were no adverse events. In-hospital rebleeding was 7.3% and 3.9% presented with rebleeding within 30 days. Average procedure duration was 22.9 minutes and average length of hospital stay was 11.3 days. CONCLUSIONS: The Instinct clip, when used for UGIB, seems to be safe and effective with similar rebleeding rates compared with other modalities.

RESUMEN

When chromosomal DNA is damaged, progression through the cell cycle is halted to provide the cells with time to repair the genetic material before it is distributed between the mother and daughter cells. In Saccharomyces cerevisiae, this cell cycle arrest occurs at the G2/M transition. However, it is also necessary to restrain exit from mitosis by maintaining Bfa1-Bub2, the inhibitor of the Mitotic Exit Network (MEN), in an active state. While the role of Bfa1 and Bub2 in the inhibition of mitotic exit when the spindle is not properly aligned and the spindle position checkpoint is activated has been extensively studied, the mechanism by which these proteins prevent MEN function after DNA damage is still unclear. Here, we propose that the inhibition of the MEN is specifically required when telomeres are damaged but it is not necessary to face all types of chromosomal DNA damage, which is in agreement with previous data in mammals suggesting the existence of a putative telomere-specific DNA damage response that inhibits mitotic exit. Furthermore, we demonstrate that the mechanism of MEN inhibition when telomeres are damaged relies on the Rad53-dependent inhibition of Bfa1 phosphorylation by the Polo-like kinase Cdc5, establishing a new key role of this kinase in regulating cell cycle progression.

RESUMEN

Plant-soil feedback (PSF) processes impact plant productivity and ecosystem function, but they are poorly understood because PSFs vary significantly with plant and soil type, plant growth stage, and environmental conditions. Controlled greenhouse studies are essential to unravel the mechanisms associating PSFs with plant productivity; however, successful implementation of these controlled experiments is constrained by our understanding of the persistence of the soil microbiome during the transition from field to greenhouse. This study evaluates the preservation potential of a field soil microbiome when stored in the laboratory under field temperature and moisture levels. Soil microbial diversity, taxonomic composition, and functional potential were evaluated via amplicon sequencing at the start of storage (W0), week 3 (W3), week 6 (W6), and week 9 (W9) to determine the effect of storage time on soil microbiome integrity. Though microbial richness remained stable, Shannon diversity indices decreased significantly at W6 for bacteria/archaea and W3 for fungi. Bacterial/archaeal community composition also remained stable, whereas the fungal community changed significantly during the first 3 weeks. Functional predictions revealed increased capacity for chemoheterotrophy for bacteria/archaea and decreased relative proportions of arbuscular mycorrhizal and ectomycorrhizal fungi. We show that preservation of the field soil microbiome must be a fundamental component of experimental design. Either greenhouse experiments should be initiated within 3 weeks of field soil collection, or a preliminary incubation study should be conducted to determine the time and storage conditions required to sustain the integrity of the specific field soil microbiome being studied.

RESUMEN

PURPOSE: The study aims to explore unmet social needs and sources of financial toxicities in patients as noted by health care professionals and researchers in cancer supportive care, shedding light on potential health disparities. METHODS: In this cross-sectional survey, we anonymously surveyed active members of the Multinational Association of Supportive Care in Cancer (MASCC). The survey, structured in three sections, included questions regarding the routine assessment of social needs during patient consultations, sociodemographic aspects, factors influencing financial toxicity (FT), perceived support for managing FT, and available/desirable resources. RESULTS: A total of 218 MASCC members were included, predominantly from high-income countries (HIC, 73.4%), with many age 41-60 years (56.5%) and female (56.9%). Drug/treatment cost and insurance coverage were the main sources for FT among the HIC, whereas participants from low-middle-income countries (LMIC) considered transportation cost, loss of employment because of cancer diagnosis, and unavailability of return-to-work services as the top three sources of FT. Respondents from LMIC (adjusted odds ratio [aOR], 3.01 [95% CI, 1.15 to 7.93]) and physicians (aOR, 2.67 [95% CI, 1.15 to 6.21]) were more likely to routinely assess financial coverages. Socioeconomic status was consistently ranked as one of the top three sources of financial toxicities by participants from LMIC (34%), HIC excluding the United States (38%), those who do not self-identify as racial/ethnic minority (36%), and physicians (40%). CONCLUSION: This global survey of health care professionals and researchers in HIC and LMIC revealed varying approaches to assessing financial coverage and social needs. Socioeconomic status emerged as a consistent concern across countries, affecting financial toxicities. The study highlights the need for tailored approaches and improved resource visibility while emphasizing clinicians' pivotal role in addressing financial aspects of cancer care.

RESUMEN

Excessive lipolysis in white adipose tissue (WAT) leads to insulin resistance (IR) and ectopic fat accumulation in insulin-sensitive tissues. However, the impact of Gi-coupled receptors in restraining adipocyte lipolysis through inhibition of cAMP production remained poorly elucidated. Given that the Gi-coupled P2Y13 receptor (P2Y13-R) is a purinergic receptor expressed in WAT, we investigated its role in adipocyte lipolysis and its effect on IR and metabolic dysfunction-associated steatotic liver disease (MASLD). In humans, mRNA expression of P2Y13-R in WAT was negatively correlated to adipocyte lipolysis. In mice, adipocytes lacking P2Y13-R displayed higher intracellular cAMP levels, indicating impaired Gi signaling. Consistently, the absence of P2Y13-R was linked to increased lipolysis in adipocytes and WAT explants via hormone-sensitive lipase activation. Metabolic studies indicated that mice lacking P2Y13-R showed a greater susceptibility to diet-induced IR, systemic inflammation, and MASLD compared with their wild-type counterparts. Assays conducted on precision-cut liver slices exposed to WAT conditioned medium and on liver-specific P2Y13-R-knockdown mice suggested that P2Y13-R activity in WAT protects from hepatic steatosis, independently of liver P2Y13-R expression. In conclusion, our findings support the idea that targeting adipose P2Y13-R activity may represent a pharmacological strategy to prevent obesity-associated disorders, including type 2 diabetes and MASLD.

RESUMEN

INTRODUCTION: Durvalumab improves survival when used as consolidation therapy after chemoradiation (CRT) in patients with stage III NSCLC. The optimal consolidation therapy for patients with EGFR-mutant (EGFRmut) stage III NSCLC remains unknown. METHODS: In this multi-institutional, international retrospective analysis across 24 institutions, we evaluated outcomes in patients with stage III EGFRmut NSCLC treated with concurrent CRT followed by consolidation therapy with osimertinib, durvalumab, or observation between 2015 and 2022. Kaplan-Meier method was used to estimate real-world progression-free survival (rwPFS, primary end point) and overall survival (secondary end point). Treatment-related adverse events (trAEs) during consolidation treatment were defined using Common Terminology Criteria for Adverse Events version 5.0. Multivariable Cox regression analysis was used. RESULTS: Of 136 patients with stage III EGFRmut NSCLC treated with definitive concurrent CRT, 56 received consolidation durvalumab, 33 received consolidation osimertinib, and 47 was on observation alone. Baseline characteristics were similar across the three cohorts. With a median follow-up of 46 months for the entire cohort, the median duration of treatment was not reached (NR) for osimertinib (interquartile range: NR-NR) and was 5.5 (interquartile range: 2.4-10.8) months with durvalumab. After adjusting for nodal status, stage III A/B/C, and age, patients treated with consolidation osimertinib had significantly longer 24-month rwPFS compared to those treated with durvalumab or in the observation cohorts (osimertinib: 86%, durvalumab: 30%, observation: 27%, p < 0.001 for both comparisons). There was no difference in rwPFS between the durvalumab and the observation cohorts. No significant difference in overall survival across the three cohorts was detected, likely due to the limited follow-up. Any-grade trAE occurred in 52% (2 [6.1%] grade ≥3) and 48% (10 [18%] grade ≥3) of patients treated with osimertinib and durvalumab, respectively. Of 45 patients who progressed on consolidation durvalumab, 37 (82%) subsequently received EGFR tyrosine kinase inhibitors. Of these, 14 (38%) patients developed trAEs including five patients with pneumonitis (14%; 2 [5.4%] grade ≥3) and five patients with diarrhea (14%; 1 [2.7%] grade ≥3). CONCLUSIONS: This study suggests that among patients with stage III unresectable NSCLC with a sensitizing EGFR mutation, consolidation osimertinib was associated with a significantly longer rwPFS compared to durvalumab or observation. No unanticipated safety signals were observed with consolidation osimertinib.
