ABSTRACTFood security is one of the most researched social determinants of health (SDoH), however, there is a lack of literature on the impact of food security on cardiovascular disease in pregnancy. The primary objective was to examine the association between food security with hypertensive disorders of pregnancy. We performed a cross‐sectional analysis of 2019–2022 data from the National Health Interview Survey. The study population included women of childbearing age who were either pregnant or recently pregnant. Logistic regression models were developed to examine the association between food security and hypertensive disorders of pregnancy. Of the 1635 women included in the analysis, the rate of hypertensive disorders of pregnancy was 11.1% and the rate of low and very low food security was 5.3% and 4.0%, respectively. The prevalence was 5.8% for hyperlipemia, 0.3% for cardiovascular disease, and 10.5% for diabetes mellitus. The odds of hypertensive disorders of pregnancy were statistically significantly increased among women with low food security compared to women with high food security (odds ratio [OR] 2.40, 95% confidence interval [CI]: 1.19–4.81) after adjusting for age, race, ethnicity, insurance status, body mass index, hyperlipidemia, diabetes mellitus, and cardiovascular disease. Further studies are needed to elucidate the causes of hypertensive disorders of pregnancy and interventions to address including the Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) and food pantries, as it may be more feasible to address issues of food security among pregnant women.

The NCCN Guidelines for Survivorship include recommendations for screening, evaluation, and treatment of psychosocial and physical problems resulting from adult-onset cancer and its treatment. They also include recommendations to promote healthy behaviors and immunizations in survivors and provide a framework for care coordination. These NCCN Guidelines Insights summarize the panel’s current recommendations regarding sexual health and fertility.

Multigene panel testing has allowed for the detection of a growing number of inherited pathogenic/likely pathogenic variants in people at high risk of cancer, including endometrial cancer (EC). Hereditary syndromes associated with EC include Lynch syndrome, PTEN hamartoma tumor syndrome, and Peutz-Jeghers syndrome. This manuscript provides the latest recommendations from the NCCN Guidelines for Genetic/Familial High-Risk Assessment: Colorectal, Endometrial, and Gastric on the screening and management of EC in patients at high risk for these syndromes, as well as the advantages and limitations of multigene panel testing. This manuscript also describes recent updates to these guidelines regarding de-implementation of colon cancer screening in individuals with CHEK2 pathogenic/likely pathogenic variants, based on the most up-to-date evidence regarding the association between CHEK2 pathogenic/likely pathogenic variants and colon cancer risk.

Immunotherapy has shown significant improvement in the survival of patients with hepatocellular carcinoma (HCC) compared to TKIs as first-line treatment. Unfortunately, approximately 30% of HCC exhibits intrinsic resistance to ICIs, making new therapeutic combinations urgently needed. The dysregulation of the Notch signaling pathway observed in HCC can affect immune cell response, reducing the efficacy of cancer immunotherapy. Here, we provide an overview of how Notch signaling regulates immune responses and present the therapeutic rationale for combining Notch signaling inhibition with ICIs to improve HCC treatment. Moreover, we propose using exosomes as non-invasive tools to assess Notch signaling activation in hepatic cancer cells, enabling accurate stratification of patients who can benefit from combined strategies.

OBJECTIVE This study aimed to evaluate local control (LC) of tumors, patient overall survival (OS), and the safety of stereotactic radiosurgery (SRS) for esophageal cancer brain metastases (EBMs). METHODS This retrospective cohort study used data from 15 International Radiosurgery Research Foundation facilities encompassing 67 patients with 185 EBMs managed using SRS between January 2000 and May 2022. The median patient age was 63 years, with a male predominance (92.5%). Most patients (64.2%) had a single brain metastasis, while 7.5% had more than 5 metastases. The median tumor volume was 0.9 cm 3 , and the median margin dose delivered to the tumor was 20 Gy. RESULTS The median OS post-SRS was 15.2 months, with 1- and 2-year OS rates of 65.7% and 32.3%, respectively. A significant inverse correlation was found between the number of EBMs and OS in the univariable analysis. LC rates at 1 and 2 years were 89% and 76%, respectively. Adverse radiation effects (AREs) were observed in 17.9% of patients, with 13.4% being mild and transient and 4.5% severely symptomatic (Common Terminology Criteria for Adverse Events grade 3). New intracranial disease developed in 58.2% of patients, with 1- and 2-year rates of 58% and 73%, respectively. CONCLUSIONS SRS for EBMs demonstrated high survival rates and effective tumor control, with a low incidence of severe AREs. These findings highlight the potential role of SRS in the multidisciplinary multimodality management paradigm of EBM.

OBJECTIVE To evaluate a regimen of inhaled Technosphere insulin (TI) plus insulin degludec in adults with type 1 diabetes, who prestudy were predominately using either an automated insulin delivery (AID) system or multiple daily insulin injections (MDI) with continuous glucose monitoring. RESEARCH DESIGN AND METHODS At 19 sites, adults with type 1 diabetes were randomly assigned to TI plus insulin degludec (N = 62) or usual care (UC) with continuation of prestudy insulin delivery method (N = 61) for 17 weeks. RESULTS Prestudy, AID was used by 48% and MDI by 45%. Mean ± SD HbA1c was 7.57% ± 0.97% at baseline and 7.62% ± 1.06% at 17 weeks in the TI group and 7.59% ± 0.80% and 7.54% ± 0.77%, respectively, in the UC group (adjusted difference 0.11%, 95% CI −0.10 to 0.33, P value for noninferiority = 0.01). HbA1c improved from baseline to 17 weeks by >0.5% (5.5 mmol/mol) in 12 (21%) in the TI group and in 3 (5%) in the UC group and worsened by >0.5% (5.5 mmol/mol) in 15 (26%) in the TI group and in 2 (3%) in the UC group. The most common TI side effect was a brief cough; eight participants discontinued TI due to side effects. CONCLUSIONS In adults with type 1 diabetes, HbA1c after 17 weeks with a regimen of TI and degludec was noninferior to UC, which consisted predominately of either AID or MDI. TI should be considered an option for people with type 1 diabetes, particularly those who are motivated to further reduce postprandial hyperglycemia.

Background: Hematopoietic stem cell transplant (HSCT) based gene therapies (GT) have successfully demonstrated significant reduction in vasocclusive crises (VOCs) associated with sickle cell disease (SCD). The efficacy and safety of these products is well established across multiple clinical trials (Kanter et al. NEJM 2022, Frangoul et al. NEJM 2024). This led to the Food and Drug Administration (FDA) approval of the lentiviral-based gene addition product (lovotibeglogene autotemcel) and CRISPR-Cas9 based gene editing product (exagamglogene autotemcel) for patients with SCD above 12 years of age. As these therapies have a different logistical process compared to a standard allogeneic HSCT, there is a need to develop a collaborative transition of care plan for these patients and families prior to and long after completion of transformative therapies. Methods: Upper Midwest Sickle Cell Curative Therapies Consortium is a collaborative model including multiple stakeholders between 7 centers across the upper Midwest United States, the regional community-based organization (CBO) and National Marrow Donors Program (NMDP). The structure and workflow for this model was presented previously (Blaylark et al. ASH 2023). With the advent of commercial GTs, we developed a multi-specialty care model in collaboration with community stakeholders to address diverse patient and logistical needs for smoother transition to and from these therapies. Discussion: The initial transition is a period of potential gaps in medical care and often high anxiety for patients and families. Thus, when patients and families are considering GT, our care model engages a multidisciplinary team. As part of the comprehensive evaluation prior to gene therapy, an initial shared collaborative checklist includes an extensive medical history, assessment of treatment plan, an individualized pain plan and adherence, transfusion planning (simple or exchange) with setting of target hemoglobin and hemoglobin S% targets, and coordination of multi-specialty consults including apheresis, fertility preservation, child life, and social work. Additionally, pain, psychology, and integrative medicine specialists address not only ongoing concerns, but also help develop a plan for future transition back to the primary site of SCD care (“re-transition”) after GT. Patients undergo neuropsychological evaluations to establish baseline functioning and the role of chronic pain and fatigue, as GT can significantly impact long term cognitive functioning, emotional coping with transitions, and overall daily functioning. When appropriate and available, warm handoffs are encouraged between centers within each of these specialties. Our team also reviews available resources for education and ongoing support through the process and after from national and regional CBOs. Similarly, the post-GT transition is also a period of potential medical care gaps and high anticipated anxiety and concern, as patients go through significant unfamiliar adverse effects followed by the potential for persistent freedom from VOCs. In the post-GT transition, ongoing psychology, integrative medicine, and pain team support; peer mentoring; and support groups are critical for a smooth re-transition to post-GT care and further successful re-transition back into the community. Using this interdisciplinary approach across GT clinical trials, we successfully weaned opioids in 83% of patients (5/6) by day 60 post-GT infusion and successful re-transition of these patients, further highlighting the role of interdisciplinary care. Our team's collaborative approach to SCD care with sickle cell specialists, transplant team and other care providers and CBO continues into the long term follow up period, including ongoing supportive services for both patients and their families. Conclusion: As newer therapies are developed and approved for transformative SCD care, development of a transitional model with early engagement of an interdisciplinary team is critical for empowering sickle cell warriors and for their successful transition back into the community.

Oncoprotein-driven human cancers exhibit replication stress (RS), leading to an increase in DNA double-strand breaks (DSB). These DSBs are repaired by one of the three main pathways - homologous recombination repair (HR), non-homologous end-joining (NHEJ), and microhomology-mediated end joining (MMEJ). Cyclin D1 (CCND1) is one of the most overexpressed oncoproteins and is universally overexpressed in mantle cell lymphoma (MCL). While CCND1 overexpression drives cells into the S-phase, its specific effects on RS and DSB repair pathways are poorly understood. Here, we investigated the impact of CCND1 overexpression on RS and DSB repair mechanisms in MCL. First, the expression level of CCND1 positively correlated with heightened RS, as indicated by elevated p-RPA-S33 and p-RPA S8 levels, and increased DNA damage, assessed by g-H2AX, especially in the mitotic phase, across diverse cell models, including MCL. Since CCND1-overexpressed cells proliferate rapidly, we hypothesized that some DNA repair pathways might be upregulated to meet the demand for repairing the excess RS-driven DSBs. Reporter assays demonstrated that the MMEJ pathway was specifically upregulated upon CCND1 overexpression, whereas no significant changes were observed in the HR and NHEJ pathways. Furthermore, CRISPR interference (CRISPRi)-mediated knockdown of CCND1 in MCL cells led to a significant reduction in MMEJ activity. This finding suggests the specificity of CCND1 in mediating the upregulation of the MMEJ pathway. Consistent with this, increased MMEJ activity, assessed via foci formation and immunoblotting of DNA polymerase theta expression (POLQ, encoded by POLQ gene), the primary polymerase for the MMEJ pathway, correlated with CCND1 overexpression, suggesting the crucial role of MMEJ in DSB repair processes under CCND1-overexpressed conditions. Sincethe MMEJ pathwayplays a pivotal role in repairing DSB during mitosis, we assessed the dependency of MCL cells on MMEJ-mediated DSB repair for cell survival. As expected, genetic deletion or pharmacological inhibition (ART558 and novobiocin) of POLQ in MCL cells led to increased RS and increased unrepaired DNA damage during mitosis, ultimately leading to chromosomal instability, mitotic catastrophe, and apoptosis. Additionally, the deficiency of POLQ in MCL cells resulted in increased levels of single-strand DNA, another critical biomarker for RS. Second, we found that ATM deficiency, the second most common genetic alteration after CCND1 overexpression in MCL, further increased the cellular dependence on MMEJ. Interestingly, the accumulation of unrepaired DNA damage during mitosis was notably increased in ATM-deficient CCND1-overexpressed cells. When POLQ was inhibited, a significant antitumor effect was evident in MCL cells, including ibrutinib-resistant MCL, both in vitro and in vivo, and this effect was enhanced by ATM deficiency. Further, simultaneous inhibition of both ATM (AZD0156) and POLQ was synthetic lethal in MCL cell lines and primary tumor cells from patients with MCL. Mechanistically, we observed the direct binding of CCND1 to the POLQ promoter and a corresponding upregulation of POLQ mRNA in CCND1-overexpressing cells. Consistently, a significant overexpression of POLQ mRNA was observed in primary MCL cells, compared to other non-Hodgkin lymphoma cells without CCND1 overexpression. Moreover, the positive correlation between POLQ and CCND1 expression was further validated using syngeneic B-lymphoma cells with and without CCND1 overexpression. Importantly, CRISPRi-mediated CCND1 knockdown reduced POLQ mRNA expression and the dependency of MCL cells on the MMEJ pathway for survival. In addition, ATM deficiency showed a further increase of endogenous POLQ expression and foci formation in cells with CCND1 overexpression, suggesting ATM negatively regulates the MMEJ pathway, especially in the CCND1 overexpressed background. In summary, CCND1 overexpression leads to a substantial increase in RS, intensifying the reliance on MMEJ-mediated mitotic DSB repair. Within MCL, POLQ is crucial in mitigating the adversities of CCND1-driven RS. Our data suggest that targeting the MMEJ pathway via POLQ inhibition, particularly in the presence of CCND1 overexpression and ATM deficiency, emerges as a promising therapeutic approach in oncoprotein-driven hematologic malignancies such as MCL.

Background: Rituximab, gemcitabine, and oxaliplatin (R-GemOx) is a commonly utilized chemoimmunotherapy regimen for relapsed or refractory (R/R) diffuse large B-cell lymphoma (DLBCL), especially for patients ineligible for autologous stem cell transplant (ASCT) or chimeric antigen receptor T cell therapy (CAR T). R-GemOx is used as a comparator arm in several active phase III clinical trials for R/R DLBCL, including the POLARGO (polatuzumab vedotion and R-GemOx), STARGLO (glofitamab and GemOx), SUNMO (mosunetuzumab and polatuzumab vedotin), LOTIS-5 (loncastuximab tesirine and rituximab), and EPCORE DLBCL-1 (epcoritamab) studies. However, real-world data are limited to understand the patterns of use and outcomes of R-GemOx in the US. Methods: We developed a retrospective multicenter US cohort (known as LEO CReWE) of patients with R/R DLBCL and other aggressive B-cell lymphomas at the eight US academic centers participating in the LEO Cohort Study (NCT02736357). Patients first diagnosed with DLBCL (including transformed and high-grade B-cell lymphoma) from 2007 - 2022 who received second line (2L) or later therapy for R/R DLBCL with R-GemOx were included. Baseline characteristics, treatment, and follow-up data were abstracted by chart review. Index line of therapy was defined as the first receipt of R-GemOx therapy in the 2L or later setting. Intent for CAR T and/or ASCT was evaluated at each line of therapy based on medical records at the time of treatment initiation. Subgroup analyses were pre-planned in groups of special interest, including those treated with R-GemOx without intent for ASCT or CAR T, those treated as a bridge to CAR T, and those aged 70 and older. Results: 183 patients with R/R DLBCL treated with R-GemOx were included. At time of initiation of R-GemOx, median age was 68 years (range 21-88), with 71 patients (39%) aged 70+ and 18 (10%) aged 80+. Many patients had high risk features including 13% with high grade B-cell lymphoma and 56% with IPI 3 or greater. 21% had an ECOG performance status of 2 or greater. Patients received a median of 2 lines of therapy prior to the index line of R-GemOx (range 1-7). 52% of patients did not achieve a complete response (CR) to first-line therapy, and 20% relapsed <12 months from an initial CR. In all patients receiving R-GemOx, the overall response rate (ORR) was 45% (29% CR). At a median follow-up of 39 months, median EFS was 2.3 months (95% CI: 1.8-3.2), with 12-month EFS of 21% and a 24-month EFS of 15%. Median OS was 13.5 months (95% CI: 9.6-18.1), with a 12-month OS of 52% and a 24-month OS of 38%. In patients treated without intent for ASCT or CAR T, ORR was 33% (18% CR). Median EFS was 2.0 months (95% CI: 1.6-2.5) with 12- and 24-month EFS of 14% and 9%, respectively. Median OS was 9.5 months (95% CI: 6.6-16.1) with 12- and 24-month OS of 45% and 29%, respectively. In patients receiving R-GemOx as bridging to ASCT or CAR T, ORR was 57% (35% CR). 35% received CAR T and 14% received ASCT, while the remainder did not receive the intended therapy as part of this line. Median EFS was 3.6 months (95% CI: 1.8-5.2) with 12- and 24-month EFS of 28% and 25%, respectively. Median OS was 17.4 months (95% CI: 13.4-NR); 12- and 24-month OS were 61% and 50%, respectively. In patients aged 70+, ORR was 53% (33% CR). Median EFS was 2.3 months (95% CI: 1.6-5.2), with 12- and 24-month EFS of 20% and 18%, respectively. Median OS was 13.9 months (95% CI: 8.6-30.2); 12- and 24-month OS were 57% and 39%, respectively. Conclusion: This study represents the largest reported cohort of patients treated with R-GemOx in US academic centers to date. The ORR of 45% and CR rate of 29% CR, as well as median EFS and OS of 2.3 and 13.5 months, respectively, are consistent with findings from previous phase II studies; these results highlight that responses to R-GemOx are not durable and the vast majority of patients require additional therapy. This study demonstrates real-world evidence of the efficacy of R-GemOx in a large cohort of patients with R/R DLBCL from the US over a long period, including both transplant-eligible and -ineligible patients, and patients treated in the CAR T era. These data aid in providing a benchmark for active clinical trials in the rapidly evolving landscape of R/R DLBCL therapies and allow potential comparison to a real-world cohort of patients with a broad range of clinical characteristics.
