Abstract
INTRODUCTION Older adults with cancer facing competing treatments must prioritize between various outcomes. This study assessed health outcome prioritization among older adults with cancer starting chemotherapy. METHODS Secondary analysis of a randomized trial addressing vulnerabilities in older adults with cancer. Patients completed three validated outcome prioritization tools: 1) Health Outcomes Tool: prioritizes outcomes (survival, independence, symptoms) using a visual analog scale; 2) Now vs. Later Tool: rates the importance of quality of life at three times-today versus 1 or 5 years in the future; and 3) Attitude Scale: rates agreement with outcome-related statements. The authors measured the proportion of patients prioritizing various outcomes and evaluated their characteristics. RESULTS A total of 219 patients (median [range] age 71 [65-88], 68% with metastatic disease) were included. On the Health Outcomes Tool, 60.7% prioritized survival over other outcomes. Having localized disease was associated with choosing survival as top priority. On the Now vs. Later Tool, 50% gave equal importance to current versus future quality of life. On the Attitude Scale, 53.4% disagreed with the statement "the most important thing to me is living as long as I can, no matter what my quality of life is"; and 82.2% agreed with the statement "it is more important to me to maintain my thinking ability than to live as long as possible". CONCLUSION Although survival was the top priority for most participants, some older individuals with cancer prioritize other outcomes, such as cognition and function. Clinicians should elicit patient-defined priorities and include them in decision-making.

Abstract
PURPOSE This study aims to determine whether older breast cancer survivors score lower on neuropsychological tests compared to matched non-cancer controls and to test the hypotheses that survivors who were APOE ε4 carriers would have the lowest cognitive performance but that smoking history would decrease the negative effect of ε4 on cognition. METHODS Female breast cancer survivors who had been diagnosed and treated at age 60 or older and were 5-15-year survivors (N = 328) and age and education matched non-cancer controls (N = 162) were assessed at enrollment and at 8-, 16-, and 24-month follow-ups with standard neuropsychological and psychological assessments. Blood for APOE genotyping was collected, and smoking history was assessed at enrollment. Participants were purposely recruited so that approximately 50% had a history of treatment with chemotherapy or no chemotherapy and approximately 50% had a smoking history. RESULTS After adjusting for age, cognitive reserve, depression, and fatigue, breast cancer survivors scored significantly lower on all domains of cognitive function. A significant two-way interaction demonstrated that the negative effect of ε4 on cognitive performance was stronger among survivors. A significant three-way interaction supported the hypothesis that smoking history had a protective effect on cognitive function in ε4 carriers that was more pronounced in the controls than the survivors. CONCLUSIONS The results support the long-term cognitive impact of breast cancer diagnosis and treatments on older, disease-free survivors, particularly for ε4 carriers. The results also emphasize the importance of assessing smoking history when examining APOE and cognition and are an example of the complex interactions of age, genetics, health behaviors, and disease history in determining cognitive function. IMPLICATIONS FOR CANCER SURVIVORS These results help explain why only a subset of breast cancer survivors appear to be vulnerable to cognitive problems.

Abstract
Meningococcal meningitis (MM) and invasive meningococcal disease remain a major public health problem that generates enormous public alarm. It is caused by Neisseria meningitidis, a Gram-negative diplococcus with an enormous capacity for acute and rapidly progressive disease, both episodic and epidemic in nature, with early diagnosis and treatment playing a major role. It occurs at any age, but is most common in children under 5 years of age followed by adolescents. Although most cases occur in healthy people, the incidence is higher in certain risk groups. Despite advances in reducing the incidence, it is estimated that in 2017 there were around 5 million new cases of MM worldwide, causing approximately 290,000 deaths and a cumulative loss of about 20,000,000 years of healthy life. In Spain, in the 2021/22 season, 108 microbiologically confirmed cases of MM were reported, corresponding to an incidence rate of 0.23 cases per 100,000 inhabitants. This is a curable and, above all, vaccine-preventable disease, for which the World Health Organisation has drawn up a roadmap with the aim of reducing mortality and sequelae by 2030. For all these reasons, the Illustrious Official College of Physicians of Madrid (ICOMEM) and the Medical Associations of 8 other provinces of Spain, have prepared this opinion document on the situation of MM in Spain and the resources and preparation for the fight against it in our country. The COVID-19 and Emerging Pathogens Committee of ICOMEM has invited experts in the field to participate in the elaboration of this document.

Abstract
Zika virus (ZIKV) can be vertically transmitted during pregnancy resulting in a range of adverse pregnancy outcomes. The decidua is commonly found to be infected by ZIKV, yet the acute immune response to infection remains understudied in vivo. We hypothesized that in vivo African-lineage ZIKV infection induces a pro-inflammatory response in the decidua. To test this hypothesis, we evaluated the decidua in pregnant rhesus macaques within the first two weeks following infection with an African-lineage ZIKV and compared our findings to gestationally aged-matched controls. Decidual leukocytes were phenotypically evaluated using spectral flow cytometry, and cytokines and chemokines were measured in tissue homogenates from the decidua, placenta, and fetal membranes. The results of this study did not support our hypothesis. Although ZIKV RNA was detected in the decidual tissue samples from all ZIKV infected dams, phenotypic changes in decidual leukocytes and differences in cytokine profiles suggest that the decidua undergoes mild anti-inflammatory changes in response to that infection. Our findings emphasize the immunological state of the gravid uterus as a relatively immune privileged site that prioritizes tolerance of the fetus over mounting a pro-inflammatory response to clear infection.

Abstract
BACKGROUND Recently, dynamic contrast-enhanced (DCE) MRI with ferumoxytol as contrast agent has recently been introduced for the noninvasive assessment of placental structure and function throughout. However, it has not been demonstrated under pathological conditions. PURPOSE To measure cotyledon-specific rhesus macaque maternal placental blood flow using ferumoxytol DCE MRI in a novel animal model for local placental injury. STUDY TYPE Prospective animal model. SUBJECTS Placental injections of Tisseel (three with 0.5 mL and two with 1.5 mL), monocyte chemoattractant protein 1 (three with 100 μg), and three with saline as controls were performed in a total of 11 rhesus macaque pregnancies at approximate gestational day (GD 101). DCE MRI scans were performed prior (GD 100) and after (GD 115 and GD 145) the injection (term = GD 165). FIELD STRENGTH/SEQUENCE 3 T, T1-weighted spoiled gradient echo sequence (product sequence, DISCO). ASSESSMENT Source images were inspected for motion artefacts from the mother or fetus. Placenta segmentation and DCE processing were performed for the dynamic image series to measure cotyledon specific volume, flow, and normalized flow. Overall placental histopathology was conducted for controls, Tisseel, and MCP-1 animals and regions of tissue infarctions and necrosis were documented. Visual inspections for potential necrotic tissue were conducted for the two Tisseelx3 animals. STATISTICAL TESTS Wilcoxon rank sum test, significance level P < 0.05. RESULTS No motion artefacts were observed. For the group treated with 1.5 mL of Tisseel, significantly lower cotyledon volume, flow, and normalized flow per cotyledon were observed for the third gestational time point of imaging (day ~145), with mean normalized flow of 0.53 minute-1 . Preliminary histopathological analysis shows areas of tissue necrosis from a selected cotyledon in one Tisseel-treated (single dose) animal and both Tisseelx3 (triple dose) animals. DATA CONCLUSION This study demonstrates the feasibility of cotyledon-specific functional analysis at multiple gestational time points and injury detection in a placental rhesus macaque model through ferumoxytol-enhanced DCE MRI. LEVEL OF EVIDENCE NA TECHNICAL EFFICACY: Stage 2.

Abstract
The enzyme choline acetyltransferase (ChAT) synthesizes acetylcholine from acetyl-CoA and choline at the neuromuscular junction and at the nerve terminals of cholinergic neurons. Mutations in the ChAT gene (CHAT) result in a presynaptic congenital myasthenic syndrome (CMS) that often associates with life-threatening episodes of apnea. Knockout mice for Chat (Chat-/-) die at birth. To circumvent the lethality of this model, we crossed mutant mice possessing loxP sites flanking Chat exons 4 and 5 with mice that expressed Cre-ERT2. Injection of tamoxifen (Tx) at postnatal (P) day 11 in these mice induced downregulation of Chat, autonomic failure, weakness, and death. However, a proportion of Chatflox/flox-Cre-ERT2 mice receiving at birth an intracerebroventricular injection of 2 × 1013 vg/kg adeno-associated virus type 9 (AAV9) carrying human CHAT (AAV9-CHAT) survived a subsequent Tx injection and lived to adulthood without showing signs of weakness. Likewise, injection of AA9-CHAT by intracisternal injection at P28 after the onset of weakness also resulted in survival to adulthood. The expression of Chat in spinal motor neurons of Chatflox/flox-Cre-ERT2 mice injected with Tx was markedly reduced, but AAV-injected mice showed a robust recovery of ChAT expression, which was mainly translated by the human CHAT RNA. The biodistribution of the viral genome was widespread but maximal in the spinal cord and brain of AAV-injected mice. No significant histopathological changes were observed in the brain, liver, and heart of AAV-injected mice after 1 year follow-up. Thus, AAV9-mediated gene therapy may provide an effective and safe treatment for patients severely affected with CHAT-CMS.

Abstract
The decidual immunome is dynamic, dramatically changing its composition across gestation. Early pregnancy is dominated by decidual NK cells, with a shift towards T cells later in pregnancy. However, the degree, timing, and subset-specific nature of leukocyte traffic between the decidua and systemic circulation during gestation remains poorly understood. Herein, we employed intravascular staining in pregnant C57BL/6J mice and cynomolgus macaques (Macaca fascicularis) to examine leukocyte traffic into the decidual basalis during pregnancy. Timed-mated or virgin mice were tail-vein injected with labelled αCD45 antibodies 24 hours and 5 minutes before sacrifice. Pregnant cynomolgus macaques (GD155) were infused with labelled αCD45 at 2 hours or 5 mins before necropsy. Decidual cells were isolated and resulting suspensions analyzed by flow cytometry. We found that the proportion of intravascular (IVAs)-negative leukocytes (cells labeled by the 24h infusion of αCD45 or unlabeled) decreased across murine gestation while recent immigrants (24h label only) increased in mid- to late-gestation. In the cynomolgus model our data confirmed differential labeling of decidual leukocytes by the infused antibody, with the 5 min infused animal having a higher proportion of IVAs+ cells compared to the 2hr infused animal. Decidual tissue sections from both macaques showed the presence of intravascularly labeled cells, either in proximity to blood vessels (5min infused animal) or deeper into decidual stroma (2hr infused animal). These results demonstrate the value of serial intravascular staining as a sensitive tool for defining decidual leukocyte traffic during pregnancy.

Immunological tolerance toward the semiallogeneic fetus is one of many maternal adaptations required for a successful pregnancy. T cells are major players of the adaptive immune system and balance tolerance and protection at the maternal-fetal interface; however, their repertoire and subset programming are still poorly understood. Using emerging single-cell RNA sequencing technologies, we simultaneously obtained transcript, limited protein, and receptor repertoire at the single-cell level, from decidual and matched maternal peripheral human T cells. The decidua maintains a tissue-specific distribution of T cell subsets compared with the periphery. We find that decidual T cells maintain a unique transcriptome programming, characterized by restraint of inflammatory pathways by overexpression of negative regulators (DUSP, TNFAIP3, ZFP36) and expression of PD-1, CTLA-4, TIGIT, and LAG3 in some CD8 clusters. Finally, analyzing TCR clonotypes demonstrated decreased diversity in specific decidual T cell populations. Overall, our data demonstrate the power of multiomics analysis in revealing regulation of fetal-maternal immune coexistence.

Abstract
Abstract
Background
Rezafungin is a next-generation echinocandin in development for treatment of candidaemia and invasive candidiasis (IC) and for prevention of invasive fungal disease caused by Candida, Aspergillus and Pneumocystis spp. in blood and marrow transplantation. Rezafungin once-weekly (QWk) was compared to caspofungin once-daily (QD) in two double-blind, randomized, controlled trials in patients with candidaemia and/or IC: STRIVE (Phase 2; NCT02734862) and the recently completed ReSTORE (Phase 3; NCT03667690). STRIVE demonstrated the efficacy and safety profile of rezafungin. ReSTORE showed rezafungin noninferiority to caspofungin for 30 day all-cause mortality (ACM) and global response at Day 14 with comparable safety. Patient-level meta-analyses of efficacy and safety from both trials are presented.
Methods
Details of STRIVE and ReSTORE were previously described. In this analysis of data from both trials, patients who received rezafungin QWk (400 mg in Week 1, then 200 mg) were compared with those who received caspofungin QD (70 mg on Day 1 followed by 50 mg) for ≥14 days (up to 4 weeks). Efficacy endpoints included 30 day ACM (primary US FDA), mycological response at Day 5 (secondary), and time to first negative blood culture (TTNBC) (exploratory). Safety was evaluated by adverse events (AEs).
Results
Groups were well matched (Table 1). Figure 1 shows 30 day ACM (overall and by final diagnosis). Mycological response at Day 5 was 73.4% (102/139) and 64.5% (100/155) in rezafungin and caspofungin groups, respectively (difference=9.5, 95% CI=−0.9, 19.9). In patients with positive blood culture before randomization, median TTNBC was 22.3 h in rezafungin-treated versus 26.3 h in caspofungin-treated patients (stratified log rank p=0.0034, not adjusted for multiplicity). The summary of AEs (Table 2) demonstrates similar outcomes for rezafungin and caspofungin groups.
Conclusions
In the Phase 2/3 patient-level meta-analysis, rezafungin QWk demonstrated efficacy with a similar 30 day ACM rate and safety comparable to that of caspofungin QD. Data for mycological eradication at Day 5 and TTNBC support results from the primary efficacy endpoint and provide initial evidence for the theory that high, front-loaded drug exposure leads to faster fungal clearance. Further analysis of this integrated dataset may provide additional insights on rezafungin efficacy and safety.

Abstract
Abstract
Ovarian Cancer is the 5th leading cause of mortality among women. Even with the development of modern chemo and biologic therapies, there has not been a significant increase in the progression-free and overall survival of patients with high grade serous ovarian tumors. The goal of this study is to develop an individualized cell therapy approach for immunologic targeting of this cancer. Our proposed approach is based on harvesting and subsequently arming natural immune cells present in the peritoneal fluid (ascitic fluid) that accumulates in most ovarian cancer patients and is removed by paracentesis and discarded to alleviate discomfort. Using multiparameter flow cytometry with three 16-18 component antibody panels we have carefully characterized the T cells, dendritic cells and innate lymphoid cells present in the peritoneal fluid of 15 ovarian cancer patients. Analysis of the data using tSNE identified multiple clusters of immune cell subsets. These data indicated that in each patient, a substantial percentage of adaptive and innate lymphoid cells are present that under appropriate conditions can be reactivated to recognize and target autologous tumors (Vazquez, Jessica, et al. "Identification of unique clusters of T, dendritic, and innate lymphoid cells in the peritoneal fluid of ovarian cancer patients." American Journal of Reproductive Immunology 84.3 (2020): e13284). Our goal now is to use fusokines, chimeras of two distinct cytokines, to weaponized the ascitic immune cells and employ them as autologous cell therapy against ovarian cancer. The first candidate under investigation is GIFT4, a fusokine composed of GM-CSF and IL-4 that has previously been shown to eradicate Melanoma in mouse model. Using Vector Builder, we designed and produced lentiviral vectors to express GIFT4 in primary immune cells. The efficiency of human GIFT4 expression in primary immune cells was optimized by testing different promoter constructs. The efficiency of transduction was determined by monitoring the primary immune cells for secretion of GIFT4 using IL-4 and GM-CSF ELISA. The effect of GIFT4 expression on the phenotype of the primary immune cells is under investigation using multiparameter flow cytometry. The tumor targeting potential of the GIFT4 transduced peritoneal immune cells is being investigated in an ID8 mouse model of ovarian cancer. Effects of GIFT4 on the activation of specific subtypes of ascetic immunocytes and their in vivo effects in neutralizing ID8 cells in immunocompetent C57BL/6 mice will be instrumental for developing a novel fusokine-based individualized immune cell therapy for ovarian cancer.

Abstract
Multiparameter flow cytometry is a convenient and efficient method for thorough phenotyping of cells, and especially immune cells from various tissues. We have successfully used multiparameter flow cytometry to characterize immune cells from patients with ovarian cancer and leveraged dimensionality reduction and machine learning for optimized visualization and analysis. Herein, we describe our optimized and established protocols for the labeling of cells with fluorophore-conjugated antibody panels, followed by details on data acquisition. Finally, we describe methods for analysis of the flow cytometry data using both FlowJo as well as R package, Cytofkit, for multidimensional data visualization.

Abstract
PROBLEM Mucosal-Associated Invariant T (MAIT) cells have been recently identified at the maternal-fetal interface. However, transcriptional programming of decidual MAIT cells in pregnancy remains poorly understood. METHOD OF STUDY We employed a multiomic approach to address this question. Mononuclear cells from the decidua basalis and parietalis, and control PBMCs, were analyzed via flow cytometry to investigate MAIT cells in the decidua and assess their transcription factor expression. In a separate study, both decidual and matched peripheral MAIT cells were analyzed using Cellular Indexing of Transcriptomes and Epitopes by Sequencing (CITE-seq) coupled with gene expression analysis. Lastly, decidual MAIT cells were stimulated with E.coli and expression of MR1 by antigen presenting cells was measured to evaluate decidual MAIT cell function. RESULTS First, we identified MAIT cells in both the decidua basalis and parietalis. CITE-seq, coupled with scRNA-seq gene expression analysis, highlighted transcriptional programming differences between decidual and matched peripheral MAIT cells at a single cell resolution. Transcription factor expression analysis further highlighted transcriptional differences between decidual MAIT cells and non-matched peripheral MAIT cells. Functionally, MAIT cells are skewed towards IFNγ and TNFα production upon stimulation, with E.coli leading to IFNγ production. Lastly, we demonstrate that MR1, the antigen presenting molecule restricting MAIT cells, is expressed by decidual APCs. CONCLUSION MAIT cells are present in the decidua basalis and obtain a unique gene expression profile. The presence of MR1 on APCs coupled with in vitro activation by E.coli suggests that MAIT cells might be involved in tissue-repair mechanisms at the maternal-fetal interface.

Abstract
Background and purpose
Myocarditis is a severe inflammatory heart disease and a leading cause of sudden death in young adults; but currently no specific treatment is available. Lipoxins and their derivatives promote the resolution of inflammation contributing to recover tissue homeostasis; but their role in cardiac inflammation is poorly understood.
Methods and results
BML-111, a stable lipoxin A4 receptor agonist, protects against cardiac dysfunction in a murine model of experimental autoimmune myocarditis (EAM) by preventing Ca2+ mishandling. Cardiac proteomic analysis revealed an enhanced cardiac oxidative profile in EAM-induced mice with reduced activation of NRF2, a master antioxidant transcription factor. In vitro analysis showed that 15-epi-lipoxin A4 increased systolic Ca2+ release and sarcoplasmic reticulum (SR)-Ca2+ load in cardiomyocytes isolated from wild-type mice and augmented the rate of SR-Ca2+ uptake by SERCA2a, but failed to induce any functional change in cells from Nrf2−/− mice. BML-111 increased SERCA2a cardiac expression in wild-type mice, and the transcriptional activity of Nrf2 determined SERCA2a expression in human ventricular cells. Human myocarditis-positive myocardium showed a reduced expression of both ATP2A2 (SERCA2a) and NF2L2 (NRF2).
Conclusions
Our results demonstrated new cardioprotective mechanisms of pro-resolving lipid mediators that may emerge as innovative treatments for myocarditis.

Abstract
INTRODUCTION The relationship between cognitive function and frailty in older, long-term breast cancer survivors was examined. MATERIALS AND METHODS Breast cancer survivors who were diagnosed and treated at 60 years of age or above and were 5-15 year disease-free survivors and non-cancer controls matched on age and education were evaluated with neuropsychological tests and the Comprehensive Geriatric Assessment which was used to assess frailty based on a deficit accumulation frailty index (DAFI). RESULTS Unadjusted regression analyses revealed that cancer survivors scored significantly lower on the Language (P = 0.015), Attention, Processing Speed, Executive Function (APE) (P = 0.015), and Learning and Memory (LM) (P = 0.023) domains compared to controls. However, only the LM domain remained significantly different (P = 0.002) in the adjusted analysis. Survivors had significantly higher DAFI scores compared to controls (p = 0.006) and significantly more survivors were categorized as pre-frail or frail (35%) compared to controls (23%, P = 0.009). Increasing frailty scores were associated with worse cognitive performance across all domains (all Ps ≤ 0.004). For the LM domain, there was a significant interaction (P = 0.019) between DAFI score and survivorship vs control status. Survivors demonstrated a significant linear decline in LM scores as DAFI scores increased, whereas controls demonstrated comparable scores between the robust and pre-frail DAFI groups, demonstrating decline in the frailty group only. CONCLUSION Older, long-term breast cancer survivors had lower cognitive performance and higher levels of frailty compared to controls. For the Learning and Memory domain, the decline in performance began in the pre-frail range for survivors, but not controls.

Abstract
INTRODUCTION/AIMS We studied a patient with a congenital myasthenic syndrome (CMS) caused by a dominant mutation in the synaptotagmin 2 gene (SYT2) and compared the clinical features of this patient with those of a previously described patient with a recessive mutation in the same gene. METHODS We performed electrodiagnostic (EDX) studies, genetic studies, muscle biopsy, microelectrode recordings and electron microscopy (EM). RESULTS Both patients presented with muscle weakness and bulbar deficits, which were worse in the recessive form. EDX studies showed presynaptic failure, which was more prominent in the recessive form. Microelectrode studies in the dominant form showed a marked reduction of the quantal content, which increased linearly with higher frequencies of nerve stimulation. The MEPP frequencies were normal at rest but increased markedly with higher frequencies of nerve stimulation. The EM demonstrated overdeveloped postsynaptic folding, and abundant endosomes, multivesicular bodies and degenerative lamellar bodies inside small nerve terminals. DISCUSSION The recessive form of CMS caused by a SYT2 mutation showed far more severe clinical manifestations than the dominant form. The pathogenesis of the dominant form likely involves a dominant-negative effect due to disruption of the dual function of synaptotagmin as a Ca2+ -sensor and modulator of synaptic vesicle exocytosis.

Abstract
OBJECTIVE Treatment of high-grade serous ovarian cancer (HGSOC) will benefit from early detection of cancer. Here, we provide proof-of-concept data supporting the hypothesis that circulating immune cells, because of their early recognition of tumors and the tumor microenvironment, can be considered for biomarker discovery. METHODS Longitudinal blood samples from C57BL/6 mice bearing syngeneic ovarian tumors and peripheral blood mononuclear cells (PBMC) from healthy postmenopausal women and newly diagnosed for HGSOC patients were subjected to RNASeq. The results from human immune cells were validated using Affymetrix microarrays. Differentially expressed transcripts in immune cells from tumor-bearing mice and HGSOC patients were compared to matching controls. RESULTS A total of 1282 transcripts (798 and 484, up- and downregulated, respectively) were differentially expressed in the tumor-bearing mice as compared with controls. Top 100 genes showing longitudinal changes in gene expression 2, 4, 7, and 18 days after tumor implantation were identified. Analysis of the PBMC from healthy post-menopausal women and HGSOC patients identified 4382 differentially expressed genes and 519 of these were validated through Affymetrix microarray analysis. A total of 384 genes, including IL-1R2, CH3L1, Infitm1, FP42, CXC42, Hdc, Spib, and Sema6b, were differentially expressed in the human and mouse datasets. CONCLUSION The PBMC transcriptome shows longitudinal changes in response to the progressing tumor. Several potential biomarker transcripts were identified in HGSOC patients and mouse models. Monitoring their expression in individual PBMC subsets can serve as additional discriminator for the diagnosis of HGSOC.

Abstract
INTRODUCTION Cancer patients are increasingly incorporating medical marijuana into the management of treatment-related side effects. Currently however, data is limited regarding the risks and benefits of therapeutic cannabis for cancer patients. We sought to characterize radiation oncologists' practices and opinions regarding therapeutic cannabis via a nationwide survey. MATERIALS AND METHODS An anonymous survey was distributed via email to 873 radiation oncologists in the American Society for Radiation Oncology member database. Radiation oncologists were asked their opinions and practices regarding the use of therapeutic cannabis for their patients. Bivariate analyses of potential predictors for responses were conducted using standard statistical techniques. RESULTS One hundred seven radiation oncologists completed the survey. According to the survey, 36% of respondents would recommend therapeutic cannabis to their patients to mitigate treatment toxicity. Physicians practicing in states where medical marijuana is legal were more likely to recommend it compared to physicians working in states that have not legalized medical marijuana (OR = 3.79, 1.19-12.1, p = 0.01). Seventy-one percent of respondents reported therapeutic cannabis as being effective at least some of the time for managing treatment-related toxicities. Fifty-eight percent of physicians reported lacking sufficient knowledge to advise patients regarding therapeutic cannabis, while 86% of respondents were interested in learning more about therapeutic cannabis for cancer patients. CONCLUSIONS Although a majority of radiation oncologists believe there are benefits to therapeutic cannabis, many are hesitant to recommend for or against its use. Radiation oncologists appear to be interested in learning more about how therapeutic cannabis may play a role in their patients' care.

Abstract
Objective The purpose of this study was to evaluate overall survival (OS) outcomes by race, stratified by country of origin in patients diagnosed with NSCLC in California. Methods We performed a retrospective analysis of nonsmall cell lung cancer (NSCLC) patients diagnosed between 2000 and 2012. Race/ethnicity was defined as White (W), Black (B), Hispanic (H), and Asian (A) and stratified by country of origin (US vs. non‐US [NUS]) creating the following patient cohorts: W‐US, W‐NUS, B‐US, B‐NUS, H‐US, H‐NUS, A‐US, and A‐NUS. Three multivariate models were created: model 1 adjusted for age, gender, stage, year of diagnosis and histology; model 2 included model 1 plus treatment modalities; and model 3 included model 2 with the addition of socioeconomic status, marital status, and insurance. Results A total of 68,232 patients were included. Median OS from highest to lowest were: A‐NUS (15 months), W‐NUS (14 months), A‐US (13 months), B‐NUS (13 months), H‐US (11 months), W‐US (11 months), H‐NUS (10 months), and B‐US (10 months) (p < 0.001). In model 1, B‐US had worse OS, whereas A‐US, W‐NUS, B‐NUS, H‐NUS, and A‐NUS had better OS when compared to W‐US. In model 2 after adjusting for receipt of treatment, there was no difference in OS for B‐US when compared to W‐US. After adjusting for all variables (model 3), all race/ethnicity profiles had better OS when compared to W‐US; B‐NUS patients had similar OS to W‐US. Conclusion Foreign‐born patients with NSCLC have decreased risk of mortality when compared to native‐born patients in California after accounting for treatments received and socioeconomic differences. Foreign‐born patients with NSCLC have decreased risk of mortality when compared to native born patients in California after accounting for treatments received and socioeconomic differences.

Abstract
T lymphocyte activation requires the formation of immune synapses (IS) with antigen-presenting cells. The dynamics of membrane receptors, signaling scaffolds, microfilaments, and microtubules at the IS determine the potency of T cell activation and subsequent immune response. Here, we show that the cytosolic chaperonin CCT (chaperonin-containing TCP1) controls the changes in reciprocal orientation of the centrioles and polarization of the tubulin dynamics induced by T cell receptor in T lymphocytes forming an IS. CCT also controls the mitochondrial ultrastructure and the metabolic status of T cells, regulating the de novo synthesis of tubulin as well as posttranslational modifications (poly-glutamylation, acetylation, Δ1 and Δ2) of αβ-tubulin heterodimers, fine-tuning tubulin dynamics. These changes ultimately determine the function and organization of the centrioles, as shown by three-dimensional reconstruction of resting and stimulated primary T cells using cryo-soft x-ray tomography. Through this mechanism, CCT governs T cell activation and polarity.

Abstract
Abstract
Introduction
Heart failure (HF) is a major public health problem worldwide. To date, HF with preserved ejection fraction (EF, HFpEF) represents half of all HF patients and its prevalence is increasing. HFpEF is associated with multiple comorbidities, including diabetes mellitus, pulmonary and systemic hypertension and obesity, mainly in elderly population. Accurately phenotyping HFpEF is crucial for the development of new therapies, appropriate patient stratification and the implementation of a personalised medicine. Cardiac and pulmonary remodelling play a major role in HFpEF severity but the specific mechanisms underlying cardiac failure and lung congestion, the last stage in HFpEF, in each comorbidity are incompletely understood, precluding the development of effective therapies. Aquaporins (AQP) are membrane proteins serving as water channels across the plasma membrane and control intra- and extracellular fluid volume and prompt to tissue oedema in many organs. However, its specific contribution in HFpEF has not been explored.
Purpose
We aimed to identify cardiac and pulmonary molecular changes associated to dysfunction and oedema in HFpEF, specific for each comorbidity.
Methods
A total of 48 C57BL/6 mice 10 weeks old were randomised to the following groups: control (Ctl; n=9), type I diabetes (Db; n=9), chronic hypoxia (PAH; n=10), obesity (Ob; n=10) and systemic arterial hypertension (SAH; n=10). Mice were followed for up to 2.5 years by echocardiography and lung ultrasound until they developed pulmonary oedema (HF) or died naturally. Lungs and heart were extracted and changes were determined by proteomic, immunohistochemistry and qRT-PCR.
Results
Diastolic dysfunction was observed in all comorbidities and above 50% of those mice developed HF. Db presented the highest ratio in developing HF. Db also showed the earliest mortality (47 weeks), whereas PAH, Ob and SAH mice survived for 82, 92 and 99 weeks, respectively (p<0.001 vs Ctl). A common finding in all groups was the development of different degrees o perivascular fibrosis. Db mice, the HFpEF severest group, showed an increase in pulmonary AQP1 and 5 (p<0.05 and p<0.001, respectively, vs Ctl). Upregulation of AQPs correlated with increased ventricular filling pressures (E/E', r2=07). Cardiac AQP4 was also markedly elevated in Db mice in left and right ventricle (p<0.001 and p=0.01, respectively, vs Ctl).
Conclusion
Increased AQPs in the lung is associated with a more aggressive development of congestion and HFpEF. In addition, increased AQP4 in the heart in the most aggressive form of HFpEF suggests a relevant role in cardiac oedema. Targeting AQPs in HFpEF may prevent oedema and decompensation.

Abstract
NBSGW mice are highly immunodeficient and carry a hypomorphic mutation in the c-kit gene, providing a host environment that supports robust human hematopoietic expansion without pre-conditioning. These mice thus provide a model to investigate human hematopoietic engraftment in the absence of conditioning-associated damage. We compared transplantation of human CD34+ HSPCs purified from three different sources: umbilical cord blood, adult bone marrow, and adult G-CSF mobilized peripheral blood. HSPCs from mobilized peripheral blood were significantly more efficient (as a function of starting HSPC dose) than either cord blood or bone marrow HSPCs at generating high levels of human chimerism in the murine blood and bone marrow by 12 weeks post-transplantation. While T cells do not develop in this model due to thymic atrophy, all three HSPC sources generated a human compartment that included B lymphocytic, myeloid, and granulocytic lineages. However, the proportions of these lineages varied significantly according to HSPC source. Mobilized blood HSPCs produced a strikingly higher proportion of granulocyte lineage cells (~35% as compared to ~5%), whereas bone marrow HSPC output was dominated by B lymphocytic cells, and cord blood HSPC output was enriched for myeloid lineages. Following transplantation, all three HSPC sources showed a shift in the CD34+ subset towards CD45RA+ progenitors along with a complete loss of the CD45RA-CD49f+ long-term HSC subpopulation, suggesting this model promotes mainly short-term HSC activity. Mice transplanted with cord blood HSPCs maintained a diversified human immune compartment for at least 36 weeks after the primary transplant, although mice given adult bone marrow HSPCs had lost diversity and contained only myeloid cells by this time point. Finally, to assess the impact of non-HSPCs on transplantation outcome, we also tested mice transplanted with total or T cell-depleted adult bone marrow mononuclear cells. Total bone marrow mononuclear cell transplants produced significantly lower human chimerism compared to purified HSPCs, and T-depletion rescued B cell levels but not other lineages. Together these results reveal marked differences in engraftment efficiency and lineage commitment according to HSPC source and suggest that T cells and other non-HSPC populations affect lineage output even in the absence of conditioning-associated inflammation.

Abstract
52 Background: Older adults with cancer often have age-associated vulnerabilities and challenges, especially during hospitalization. Geriatric assessment (GA) can help identify such vulnerabilities, generate recommendations, and guide the choice of interventions. Recently, GA-driven interventions have been shown to decrease chemotherapy toxicity among older adults with cancer in the outpatient setting. However, few studies have examined its role in the inpatient setting. Our purpose was to evaluate the feasibility of GA-driven interventions among hospitalized older adults with cancer. Methods: Hospitalized patients, age 75+, with a solid tumor malignancy were eligible. Each patient completed a GA while hospitalized at T1 (Timepoint 1) and one-month post discharge T2 (Timepoint 2). An Advanced Practice Nurse (APN) reviewed the T1 GA, provided targeted care utilizing GA results and implemented interventions based on predefined triggers built into the GA’s various domains. An APN also completed follow-up visits by phone at 1 week and 1 month post discharge. The primary outcome was feasibility, defined as the percentage of participants who received GA-guided interventions and was pre-specified as successful if > 80% were given recommendations. A secondary outcome of the study was to capture unplanned readmissions within 1 month post discharge. Results: Between 9/19/2017 and 5/3/2019, 49 patients were eligible and 40 were enrolled, an 82% participation rate. The median age was 80.5 years (range 75-88), 58% male, 63% Non-Hispanic white, 18% Hispanic, 15% Asian, 70% > a high school education, 73% married/partner, and 48% had stage IV cancer. Most common cancer types: GI (28%), GU (23%), lung (20%). All 40 patients (100%) had ≥ 1 predefined trigger in the GA generating interventions and completed ≥ 2 follow-up visits with the APN. In total, 857 interventions were recommended, and the mean number of interventions generated per patient was 11. The top 4 interventions were Occupational Therapy/Physical Therapy (n = 66), Social Work (n = 52), Nutrition (n = 39), and Pharmacy (n = 36). Overall 89% of GA-guided interventions were implemented. Unplanned hospital readmission was low with only one patient readmitted within 30 days (3%). Conclusions: Among hospitalized adults over age 75 with cancer, using GA to identify vulnerability, and provide GA-driven multidisciplinary interventions is feasible. Further studies are warranted to examine the impact of GA-driven interventions on outcomes among hospitalized older adults with cancer.

Abstract
This study analyzed the cerebrospinal fluid features of 31 COVID-19 patients with neurological complications. We observed neither SARS-CoV-2 RNA in the cerebrospinal fluid, nor intrathecal IgG synthesis, but did observe signs of blood-brain barrier disruption. These results might serve as a basis for a better understanding of SARS-CoV-2 related neuropathogenesis.

Abstract
PROBLEM We hypothesize that activated peritoneal immune cells can be redirected to target ovarian tumors. Here, we obtain fundamental knowledge of the peritoneal immune environment through deep immunophenotyping of T cells, dendritic cells (DC), and innate lymphoid cells (ILC) of ovarian cancer patients. METHOD OF STUDY T cells, DC, and ILC from ascites of ovarian cancer patients (n = 15) and peripheral blood of post-menopausal healthy donors (n = 6) were immunophenotyped on a BD Fortessa cytometer using three panels-each composed of 16 antibodies. The data were analyzed manually and by t-SNE/DensVM. CA125 levels were obtained from patient charts. RESULTS We observed decreased CD3+ T cells and a higher proportion of activated CD4+ and effector memory CD4+ /CD8+ T cells, plasmacytoid DC, CD1c+ and CD141+ myeloid DC and CD56Hi NK cells in ascites. t-SNE/DensVM identified eight T cell, 17 DC, and 17 ILC clusters that were unique in the ascites compared to controls. Hierarchical clustering of cell frequency distinctly segregated the T-cell and ILC clusters from controls. Increased CA125 levels were associated with decreased CD8+ /CD45RA+ /CD45RO- /CCR7- T cells. CONCLUSION The identified immune clusters serve as the basis for interrogation of the peritoneal immune environment and the development of novel immunologic modalities against ovarian cancer.

Abstract
Abstract
Immune cells at the maternal-fetal interface play a complex role in regulation of vascular remodeling, fetal tolerance and protection from infection. We have previously reported the identification of two novel CD56high innate lymphoid cells (ILCs) based on Eomes (lo/hi) expression in the decidua. Preliminary experiments suggest that cytokines can modify the expression of canonical transcription factors (TF) by decidual ILCs.
Decidual specimens were dissected from term placentas and mononuclear cells (MCs) were isolated by mechanical/enzymatic disruption, then cultured in the presence of IL7/IL15, IL1β/IL23, or IL2/TGFβ for 7 days, with matched samples processed without culturing for ex vivo assessment. MCs were labeled with fluorochrome-conjugated antibodies against CD3, 14, 16, 19, 34, 45, 49a, 56, 94, 117, 127, GATA3, Eomes, RORγt, and Tbet. Data was acquired using the BD Fortessa flow cytometer and analyzed using FlowJo 10.2.
Our assessment of TF expression revealed significant differences between cytokine-stimulated cultured cells and direct ex vivo samples. GATA3 expression was highest in EomesLo (C2) and EomesHi (C10) cells cultured with IL7/IL15, compared to ex vivo cells. Interestingly, Eomes expression did not change across treatments, while Tbet expression was highest in C2/C10 cells cultured with IL7/IL15. Contrary to our expectations, culturing with IL1β/IL23 did not lead to higher RORγt expression, which was instead upregulated by IL7/IL15.
Preliminary results suggest that both C10 and C2 decidual ILCs demonstrate a level of lineage plasticity. Further analysis will reveal if these novel subsets have the capacity of transdifferentiating fully or if they maintain a limited phenotypic and functional capacity.

Abstract
OBJECTIVE We aimed to use diffusion tensor imaging (DTI) to detect alterations in white matter microstructure in older patients with breast cancer receiving chemotherapy. METHODS We recruited women age ≥60 years with stage I-III breast cancer (chemotherapy [CT] group; n = 19) to undergo two study assessments: at baseline and within one month after chemotherapy. Each assessment consisted of a brain magnetic resonance imaging scan with DTI and neuropsychological (NP) testing using the National Institutes of Health (NIH) Toolbox Cognition Battery. An age- and sex-matched group of healthy controls (HC, n = 14) underwent the same assessments at matched intervals. Four DTI parameters (fractional anisotropy [FA], mean diffusivity [MD], axial diffusivity [AD], and radial diffusivity [RD]) were calculated and correlated with NP testing scores. RESULTS For CT group but not HCs, we detected statistically significant increases in MD and RD in the genu of the corpus callosum from time point 1 to time point 2 at p < 0.01, effect size:0.3655 and 0.3173, and 95% confidence interval: from 0.1490 to 0.5821, and from 0.1554 to 0.4792, for MD and RD respectively. AD values increased for the CT group and decreased for the HC group over time, resulting in significant between-group differences (p = 0.0056, effect size:1.0215, 95% confidence interval: from 0.2773 to 1.7657). There were no significant correlations between DTI parameters and NP scores (p > 0.05). CONCLUSIONS We identified alterations in white matter microstructures in older women with breast cancer undergoing chemotherapy. These findings may potentially serve as neuroimaging biomarkers for identifying cognitive impairment in older adults with cancer.

Abstract
The maternal-fetal interface represents a unique immune privileged site that maintains the ability to defend against pathogens while orchestrating the necessary tissue remodeling required for placentation. The recent discovery of novel cellular families (innate lymphoid cells, tissue-resident NK cells) suggests that our understanding of the decidual immunome is incomplete. To understand this complex milieu, new technological developments allow reproductive immunologists to collect increasingly complex data at a cellular resolution. Polychromatic flow cytometry allows for greater resolution in the identification of novel cell types by surface and intracellular protein. Single-cell RNA-seq coupled with microfluidics allows for efficient cellular transcriptomics. The extreme dimensionality and size of data sets generated, however, requires the application of novel computational approaches for unbiased analysis. There are now multiple dimensionality reduction (tSNE, SPADE) and visualization tools (SPICE) that allow researchers to efficiently analyze flow cytometry data. Development of computational tools has also been extended to RNA-seq data (including scRNA-seq), which requires specific analytical tools. Here, we provide an overview and a brief primer for the reproductive immunology community on data acquisition and computational tools for the analysis of complex flow cytometry and RNA-seq data.

Abstract
PURPOSE Older cancer patients are at increased risk of cancer-related cognitive impairment. The purpose of this study was to assess the alterations in intrinsic brain activity associated with adjuvant chemotherapy in older women with breast cancer. METHODS Chemotherapy treatment (CT) group included sixteen women aged ≥ 60 years (range 60-82 years) with stage I-III breast cancers, who underwent both resting-state functional magnetic resonance imaging (rs-fMRI) and neuropsychological testing with NIH Toolbox for Cognition before adjuvant chemotherapy, at time point 1 (TP1), and again within 1 month after completing chemotherapy, at time point 2 (TP2). Fourteen age- and sex-matched healthy controls (HC) underwent the same assessments at matched intervals. Three voxel-wise rs-fMRI parameters: amplitude of low-frequency fluctuation (ALFF), fractional ALFF (fALFF), and regional homogeneity, were computed at each time point. The changes in rs-fMRI parameters from TP1 to TP2 for each group, the group differences in changes (the CT group vs. the HC group), and the group difference in the baseline rs-fMRI parameters were assessed. In addition, correlative analysis between the rs-fMRI parameters and neuropsychological testing scores was also performed. RESULTS In the CT group, one brain region, which included parts of the bilateral subcallosal gyri and right anterior cingulate gyrus, displayed increased ALFF from TP1 to TP2 (cluster p-corrected = 0.024); another brain region in the left precuneus displayed decreased fALFF from TP1 to TP2 (cluster level p-corrected = 0.025). No significant changes in the rs-fMRI parameters from TP1 to TP2 were observed in the HC group. Although ALFF and fALFF alterations were observed only in the CT group, none of the between-group differences in rs-fMRI parameter changes reached statistical significance. CONCLUSIONS Our study results of ALFF and fALFF alterations in the chemotherapy-treated women suggest that adjuvant chemotherapy may affect intrinsic brain activity in older women with breast cancer.

Abstract
Abstract
Background: Almost a quarter of older adults in the United States will identify themselves as Hispanic/Latino by 2060. Our group has previously developed and validated a self-administered geriatric assessment tool which can be used to identify functional, psychological, social and cognitive impairments among older patients with various types of cancer. Among English-speaking older adults, completing this tool using paper/pencil or a tablet takes a median of 15-21 minutes (min), with < 10% needing assistance to answer it (Hurria, JOP 2016). However, the utilization of this tool among Spanish-speaking older adults has not been tested. We assessed the feasibility of administering a translated and validated Spanish version of our geriatric assessment tool for older Hispanic women with breast cancer, and identified their preferred format (tablet or paper/pencil).
Methods: Spanish-speaking women aged ≥ 65 years with a diagnosis of breast cancer completed the geriatric assessment twice on the same day. Patients were randomized into 3 groups: paper/pencil twice; tablet and paper/pencil in random order; and tablet twice. We assessed the proportion of patients requiring assistance to complete the geriatric assessment, the time needed to complete it, and the proportion of patients who thought the geriatric assessment was difficult/very difficult.
Results: 140 older women with breast cancer completed the geriatric assessment twice and were evaluable. Mean age was 71.6 years (SD 5.8), 53% had ≤ 8th grade education, 43% were married, 45% were retired, 32% were homemakers, and 6% were employed. The participants came from 13 different Spanish-speaking countries, although 70% were born in Mexico. For 90%, Spanish was their primary language, and 75% spoke only in Spanish at home. Regarding computer skills, 64% of the patients said they had none. 39% (n = 54) were unable to complete the geriatric assessment on their own; mean time to complete the geriatric assessment was 29 min (range 8-90); and 28% (n = 39) thought the geriatric assessment was difficult/very difficult. The most common reasons for needing assistance were difficulty understanding questions (39%) and visual problems (31%). Patients with ≤ 8th grade education took longer to complete the geriatric assessment (mean 37.2 vs 29.4 min, p < 0.01), and more often needed help completing the assessment (51% vs 19%, p < 0.01) than those with ≥9th grade education. 53% of the participants preferred using a tablet to answer the geriatric assessment, while 47% preferred paper/pencil.
Conclusions: A substantial proportion of Spanish-speaking older women with breast cancer required assistance to complete our self-administered geriatric assessment tool. This may be a consequence of the low educational level we found among this patient population. Tailoring assessments for diverse populations with particular attention to educational level is needed in multicultural settings.

Abstract
A successful pregnancy requires many physiological adaptations from the mother, including the establishment of tolerance toward the semiallogeneic fetus. Innate lymphoid cells (ILCs) have arisen as important players in immune regulation and tissue homeostasis at mucosal and barrier surfaces. Dimensionality reduction and transcriptomic analysis revealed the presence of two novel CD56Bright decidual ILCs that express low T-bet and divergent Eomes levels. Transcriptional correlation with recently identified first trimester decidual dNKs suggests that these novel decidual ILCs might be present throughout pregnancy. Functional testing with permutation analysis revealed production of multiple factors by individual cells, with a preference for IFNγ and VEGF. Overall, our data suggests continuity of a unique decidual innate lymphocytes across pregnancy with a polyfunctional functional profile conducive for pregnancy.

Abstract
Adaptive immune system, principally governed by the T cells-dendritic cells (DCs) nexus, is an essential mediator of gestational fetal tolerance and protection against infection. However, the exact composition and dynamics of DCs and T cell subsets in gestational tissues are not well understood. These are controlled in human physiology by a complex interplay of alloantigen distribution and presentation, cellular/humoral active and passive tolerance, hormones/chemokines/angiogenic factors and their gradients, systemic and local microbial communities. Reductive discrimination of these factors in physiology and pathology of model systems and humans requires simplification of the model and increased resolution of interrogative technologies. As a baseline, we have studied the gestational tissue dynamics in the syngeneic C57BL/6 mice, as the simplest immunological environment, and focused on validating the approach to increased data density and computational analysis pipeline afforded by highly polychromatic flow cytometry and machine learning interpretation. We mapped DC and T cell subsets, and comprehensively examined their maternal (decidual)-fetal (placental) interface dynamics. Both frequency and composition of decidual DCs changed across gestation, with a dramatic increase in myeloid DCs in early pregnancy, and exclusion of plasmacytoid DCs. CD4+ T cells, in contrast, were lower at all gestational ages and an unusual CD4-CD8-TCRαβ+group was prominent at mid-pregnancy. Dimensionality reduction with machine learning-aided clustering revealed that CD4-CD8- T cells were phenotypically different from CD4+ and CD8+ T cells. Additionally, divergence between maternal decidual and fetal placental compartment was prominent, with absence of DCs from the placenta, but not decidua or embryo. These results provide a novel framework and a syngeneic baseline on which the specific role of alloantigen/tolerance, polymicrobial environment, and models of pregnancy pathology can be precisely modeled and analyzed.

Abstract
Hepatoblastoma is the most common malignant pediatric liver cancer. Histological evaluation of tumor biopsies is used to distinguish among the different subtypes of hepatoblastoma, with fetal and embryonal representing the two main epithelial components. With frequent CTNNB1 mutations, hepatoblastoma is a Wnt/β‐catenin‐driven malignancy. Considering that Wnt activation has been associated with tumor metabolic reprogramming, we characterized the metabolic profile of cells from hepatoblastoma and compared it to cells from hepatocellular carcinoma. First, we demonstrated that glucose transporter GLUT3 is a direct TCF4/β‐catenin target gene. RNA sequencing enabled to identify molecular and metabolic features specific to hepatoblastoma and revealed that several glycolytic enzymes are overexpressed in embryonal‐like compared to fetal‐like tumor cells. This led us to implement successfully three biomarkers to distinguish embryonal from fetal components by immunohistochemistry from a large panel of human hepatoblastoma samples. Functional analyses demonstrated that embryonal‐like hepatoblastoma cells are highly glycolytic and sensitive to hexokinase‐1 silencing. Altogether, our findings reveal a new, metabolic classification of human hepatoblastoma, with potential future implications for patients’ diagnosis and treatment.
