Comparison of outcomes by race among a population-based matched sample of multiple myeloma patients.

Purpose: It is important to understand racial inequities in multiple myeloma treatment and survival, particularly in the Midwest where clear differences exist in cancer incidence and mortality. Since age and geographic location can greatly impact treatment and prognosis, matching patients on these characteristics can help identify reasons for outcome differences.

Methods: Retrospective data from the Iowa Cancer Registry's Surveillance, Epidemiology, and End Results database were analyzed for adult patients diagnosed with first primary MM between 1/1/2010-12/31/2019.

Explainable artificial intelligence for reliable water demand forecasting to increase trust in predictions.

The "EU Artificial Intelligence Act" sets a framework for the implementation of artificial intelligence (AI) in Europe. As a legal assessment reveals, AI applications in water supply systems are categorised as high-risk AI if a failure in the AI application results in a significant impact on physical infrastructure or supply reliability. The use case of water demand forecasts with AI for automatic tank operation is for example categorised as high-risk AI and must fulfil specific requirements regarding model transparency (traceability, explainability) and technical robustness (accuracy, reliability).

Evaluating machine learning model bias and racial disparities in non-small cell lung cancer using SEER registry data.

Background: Despite decades of pursuing health equity, racial and ethnic disparities persist in healthcare in America. For cancer specifically, one of the leading observed disparities is worse mortality among non-Hispanic Black patients compared to non-Hispanic White patients across the cancer care continuum. These real-world disparities are reflected in the data used to inform the decisions made to alleviate such inequities.

Care Patterns and Outcomes for Intrahepatic Cholangiocarcinoma by Rurality of Patient Residence in a Midwestern State.

Background: Intrahepatic cholangiocarcinoma (ICC) is the second most common malignancy of the liver and has the worst prognosis of any tumor arising from the liver, with a 5-year survival as low as 10%. However, whether the rurality of a patient's residence impacts care received and survival has not been well studied. We aimed to assess differences in care patterns associated with the rurality of patient's residences and their impact on survival outcomes, hypothesizing that patients in rural areas would experience lower survival.

Patterns of care and outcomes for hepatocellular carcinoma and pancreatic cancer based on rurality of patient's residence in a rural midwestern state.

Background: Although advancements in surgical planning and multidisciplinary care have improved the survival of patients with hepatopancreatic cancers in recent years, the impact of the rurality of patient residence on care received and survival is not well known. We aimed to assess the association between the rurality of a patient's residence and cancer-specific survival outcomes among patients with hepatocellular carcinoma (HCC) and pancreatic cancer (PC) in Iowa, hypothesizing that patients in rural areas would experience lower survival.

Methods: Adult patients diagnosed with HCC or PC between 2010 and 2020 were identified using the Iowa Cancer Registry.

Outcome-Orientated Organ Allocation-A Composite Risk Model for Pancreas Graft Evaluation and Acceptance.

: Pancreas transplantation (PTX) remains the most effective treatment to prevent long-term complications and provide consistent euglycemia in patients with endocrine pancreatic insufficiency, mainly in type I diabetic patients. Considering early graft loss (EGL) and the perioperative complication rate, an optimal risk stratification based on donor risk factors is paramount. : In our single-center study, we retrospectively assessed the risk factors for EGL and reduced graft survival in 97 PTXs (82 simultaneous pancreas and kidney [SPK], 11 pancreases transplanted after kidney [PAK] and 4 pancreases transplanted alone [PTA]) between 2010 and 2021.

Alzheimer's Disease Clinical Trials: What Have We Learned From Magnetic Resonance Imaging.

Alzheimer's disease (AD) is the leading cause of cognitive impairment and dementia worldwide with rising prevalence, incidence and mortality. Despite many decades of research, there remains an unmet need for disease-modifying treatment that can significantly alter the progression of disease. Recently, with United States Food and Drug Administration (FDA) drug approvals, there have been tremendous advances in this area, with agents demonstrating effects on cognition and biomarkers.

Geographic distance to Commission on Cancer-accredited and nonaccredited hospitals in the United States.

Purpose: The Commission on Cancer (CoC) establishes standards to support multidisciplinary, comprehensive cancer care. CoC-accredited cancer programs diagnose and/or treat 73% of patients in the United States. However, rural patients may experience diminished access to CoC-accredited cancer programs.

Challenges in collecting information on sexual orientation and gender identity for cancer patients: perspectives of hospital and central cancer registry abstractors.

Purpose: Sexual and gender minority (SGM) populations experience cancer treatment and survival disparities; however, inconsistent sexual orientation and gender identity (SOGI) data collection within clinical settings and the cancer surveillance system precludes population-based research toward health equity for this population. This qualitative study examined how hospital and central registry abstractors receive and interact with SOGI information and the challenges that they face in doing so.

Methods: We conducted semi-structured interviews with 18 abstractors at five Surveillance, Epidemiology, and End Results (SEER) registries, as well as seven abstractors from commission on cancer (CoC)-accredited hospital programs in Iowa.

Faecal egg count reduction tests and nemabiome analysis reveal high frequency of multi-resistant parasites on sheep farms in north-east Germany involving multiple strongyle parasite species.

Anthelmintic resistance in sheep parasitic gastrointestinal nematodes is widespread and a severe health and economic issue but prevalence of resistance and involved parasite species are unknown in Germany. Here, the faecal egg count reduction test (FECRT) was performed on eight farms using fenbendazole, ivermectin and moxidectin and on four farms using only moxidectin. A questionnaire was used to obtain data on management practices to potentially identify risk factors for presence of resistance.

Identifying predictors of COVID-related delays in cancer-specific medical care.

Purpose: Evidence of the impact of the COVID-19 pandemic on cancer prevention and control is growing, but little is known about patient-level factors associated with delayed care. We analyzed data from a survey focused on Iowan cancer patients' COVID-19 experiences in the early part of the pandemic.

Methods: Participants were recruited from the University of Iowa Holden Comprehensive Cancer Center's Patients Enhancing Research Collaborations at Holden (PERCH) program.

Neighbourhood species richness and drought-tolerance traits modulate tree growth and δ C responses to drought.

Mixed-species forests are promoted as a forest management strategy for climate change adaptation, but whether they are more resistant to drought than monospecific forests remains contested. In particular, the trait-based mechanisms driving the role of tree diversity under drought remain elusive. Using tree cores from a large-scale biodiversity experiment, we investigated tree growth and physiological stress responses (i.

Levels and drivers of burnout during the COVID-19 pandemic among a diverse group of resident physicians.

Objectives: Evidence has shown significant impacts of the COVID-19 pandemic on physicians. We hypothesized that these effects would impact surgical and non-surgical resident education differently, with non-surgical specialties being more heavily impacted by frontline work and surgical specialties losing elective cases.

Methods: We examined well-being and burnout among resident physicians in surgical and non-surgical specialties during the peak of the COVID-19 pandemic using the Mayo Physician Well-Being Index (WBI).

Perspectives on Referring for Rectal Cancer Surgery: a Survey Study of Gastroenterologist and General Surgeons in Iowa.

Purpose: To understand referral practices for rectal cancer surgical care and to secondarily determine differences in referral practices by two main hypothesized drivers of referral: the rurality of the community endoscopists' practice and their affiliation with a colorectal surgeon.

Methods: Community gastroenterologists and general surgeons in Iowa completed a mailed questionnaire on practice demographics, volume, and referral practices for rectal cancer patients. Rurality was operationalized with RUCA codes.

Safety and efficacy of factor XIa inhibition with milvexian for secondary stroke prevention (AXIOMATIC-SSP): a phase 2, international, randomised, double-blind, placebo-controlled, dose-finding trial.

Background: People with factor XI deficiency have lower rates of ischaemic stroke than the general population and infrequent spontaneous bleeding, suggesting that factor XI has a more important role in thrombosis than in haemostasis. Milvexian, an oral small-molecule inhibitor of activated factor XI, added to standard antiplatelet therapy, might reduce the risk of non-cardioembolic ischaemic stroke without increasing the risk of bleeding. We aimed to estimate the dose-response of milvexian for recurrent ischaemic cerebral events and major bleeding in patients with recent ischaemic stroke or transient ischaemic attack (TIA).

The relevance of oral exposure in the workplace: a systematic review and meta-analysis.

Introduction: The inclusion of all relevant exposure routes in the exposure assessment is essential for the protection of workers. However, under European chemical regulations but also for workplace risk assessments according to occupational safety and health (OSH) requirements, the quantitative assessment of oral exposure is usually neglected assuming good occupational hygiene. In contrast, several studies point to the importance of unintentional ingestion in the workplace.

Efficacy of flukicides against Fasciola hepatica and first report of triclabendazole resistance on German sheep farms.

Fasciola hepatica infections lead to severe health problems and production losses in sheep farming, if not treated effectively. Triclabendazole has been used extensively over decades due to its unique efficacy range against all definitive hostfluke stages but published data about the susceptibility of F. hepatica to anthelmintics in Germany are lacking.

Locations of COVID-19 vaccination provision: Urban-rural differences.

Purpose: Our goal was to compare locations of COVID-19 vaccine provision in urban and rural communities over the course of the pandemic.

Methods: We used the Iowa Immunization Registry Information System (IRIS) to identify the organizations providing COVID-19 vaccines (eg, pharmacies, public health departments, and medical providers). Proportions of first-dose vaccines by organization type and patient census-based statistical area were generated.

Antiplatelet Treatment Patterns and Outcomes for Secondary Stroke Prevention in the United Kingdom.

Introduction: Stroke is a leading cause of death and disability worldwide. Antiplatelet therapies are recommended to reduce the risk of recurrent stroke in patients with ischemic stroke/transient ischemic attack (IS/TIA). This study evaluated outpatient antiplatelet treatment patterns and outcomes for secondary stroke prevention (SSP) among UK adults without atrial fibrillation who were hospitalized for IS/TIA.

Post-ischemic ubiquitination at the postsynaptic density reversibly influences the activity of ischemia-relevant kinases.

Ubiquitin modifications alter protein function and stability, thereby regulating cell homeostasis and viability, particularly under stress. Ischemic stroke induces protein ubiquitination at the ischemic periphery, wherein cells remain viable, however the identity of ubiquitinated proteins is unknown. Here, we employed a proteomics approach to identify these proteins in mice undergoing ischemic stroke.

Diagnosing Provider, Referral Patterns, Facility Type, and Patient Satisfaction Among Iowa Rectal Cancer Patients.

Purpose: Rectal cancer treatment at high-volume centers is associated with higher likelihood of guideline-concordant care and improved outcomes. Whether rectal cancer patients are referred for treatment at high-volume hospitals may depend on diagnosing provider specialty. We aimed to determine associations of diagnosing provider specialty with treating provider specialty and characteristics of the treating facility for rectal cancer patients in Iowa.

Comparing COVID-19 Response Behaviors between a Cancer Patient Sample and a Population-Based Cancer-Free Sample in a Rural Midwestern State.

Introduction: The COVID-19 pandemic caused an increase in fear, anxiety, and depressive symptoms globally. For populations at increased risk for adverse outcomes due to illness, such as cancer patients, these worries may have been exacerbated. Understanding how the pandemic impacted cancer patients will inform better preparation for future events that cause disturbances to cancer care delivery.

Assessing Completeness of Cancer Treatment Data from an Academic Medical Center's Tumor Registry Through Comparison to the Central Registry.

Background: Researchers often rely on hospital tumor registry data to provide comprehensive cancer therapy information. The purpose of this study was to determine the completeness of treatment information found in the abstracted records of patients seen at an academic medical center located in a rural Midwestern state.

Approach: The cohort included 846 Iowa residents diagnosed with a single malignant tumor of the female breast, colon/rectum, lung, pancreas, or prostate in 2017-2018 with an abstract recorded by the academic medical center and at least 1 other hospital.
