Germline mutation landscape of DNA damage repair genes in African Americans with prostate cancer highlights potentially targetable RAD genes.

In prostate cancer, emerging data highlight the role of DNA damage repair genes (DDRGs) in aggressive forms of the disease. However, DDRG mutations in African American men are not yet fully defined. Here, we profile germline mutations in all known DDRGs (N = 276) using whole genome sequences from blood DNA of a matched cohort of patients with primary prostate cancer comprising of 300 African American and 300 European Ancestry prostate cancer patients, to determine whether the mutation status can enhance patient stratification for specific targeted therapies.

Prospective quality of life in men choosing open vs. robotic radical prostatectomy: long-term results from a racially diverse multi-institutional database.

Purpose: To compare 5-year health-related quality of life (HRQoL) outcomes between prostate cancer (CaP) patients who underwent robotic-assisted laparoscopic radical prostatectomy (RALP) versus open radical retropubic prostatectomy (RRP) and assess for racial disparities between Caucasian American (CA) and African American (AA) men undergoing surgery.

Methods: A prospective cohort study of HRQoL data was conducted on patients diagnosed with CaP from 2007 to 2017 and enrolled in the Center for Prostate Disease Research (CPDR) Multicenter National Database. Using the EPIC and SF-36 instruments, changes in urinary, sexual, bowel, and hormonal domains, as well as physical and mental component summary scores were compared across surgery type (RALP versus RRP) at pre-treatment ("baseline"), and annually for 5 years.

Translating the Diabetes Prevention Program Lifestyle Intervention to the Military Setting.

Introduction: Diabetes and obesity pose a significant burden for the U.S. military beneficiary population, creating a great need to provide evidence-based diabetes and obesity prevention services for military personnel, retirees, and their dependents.

Assessing the quality of RNA isolated from human breast tissue after ambient room temperature exposure.

High quality human tissue is essential for molecular research, but pre-analytical conditions encountered during tissue collection could degrade tissue RNA. We evaluated how prolonged exposure of non-diseased breast tissue to ambient room temperature (22±1°C) impacted RNA quality. Breast tissue received between 70 to 190 minutes after excision was immediately flash frozen (FF) or embedded in Optimal Cutting Temperature (OCT) compound upon receipt (T0).

The Likely Underestimated Impact of Lifestyle Intervention: Diabetes Prevention Program Translation Examples.

Introduction: Lifestyle interventions promoting weight loss and physical activity are important elements of prevention efforts with the evaluation of program impact typically limited to weight loss. Unfortunately, diabetes/cardiovascular disease risk factors and activity are infrequently reported and inconsistent in findings when examined. This inconsistency may partially be due to a lack of consideration for ceiling effects because of broad risk profile inclusion criteria in community translation efforts.

Survival among Breast Cancer Patients: Comparison of the U.S. Military Health System with the Surveillance, Epidemiology and End Results Program.

Introduction: Accessibility to health care is important to cancer survival. The U.S.

Dual use of cigarettes and smokeless tobacco among active duty service members in the US military.

The high prevalence of dual use of cigarettes and smokeless tobacco is a unique tobacco use behavior in the US military population. However, dual tobacco use has rarely been addressed in active duty populations. We aimed to identify factors contributing to dual tobacco use among active duty service members from Army and Air Force.

Genetic testing in Non-Hispanic Black women with breast cancer treated within an equal-access healthcare system.

Purpose: Identification of women with hereditary forms of cancer allows for precision medicine approaches to improve survival. Non-Hispanic Black (NHB) women in the US general population are less likely to undergo genetic testing or utilize risk-reducing strategies. Whether these disparities exist within the equal-access US military healthcare system is not known.

New Selective Inhibitors of ERG Positive Prostate Cancer: ERGi-USU-6 Salt Derivatives.

Prostate cancer is among the leading causes of cancer related death of men in the United States. The gene fusion leading to overexpression of near full-length transcript and protein represents most prevalent (50-65%) prostate cancer driver gene alterations. The ERG oncoprotein overexpression persists in approximately 35% of metastatic castration resistant prostate cancers.

Estimating patient health in prostate cancer treatment counseling.

Background: We assessed the concordance among urologists' judgment of health quartiles for patients with localized prostate cancer, and compared the life expectancy (LE) and ensuing treatment recommendations when following National Comprehensive Cancer Network (NCCN) guidelines based on actuarial life tables versus the Kent model, a validated LE prediction model.

Methods: NCCN suggests using actuarial life tables and relying on surgeon assessment of patient health to increase (for the best quartile) or decrease (for the worst quartile) LE by 50%. Eleven urologic surgeons allocated quartile of health and recommended treatments for ten patient vignettes.

Indian Herb-Derived Phytoconstituent-Based Antiviral, Antimicrobial and Antifungal Formulation: An Oral Rinse Candidate for Oral Hygiene and the Potential Prevention of COVID-19 Outbreaks.

Outbreaks of emerging infectious diseases continue to challenge human health. Novel severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) has triggered a global coronavirus pandemic, known as COVID-19. Multiple variants of SARS-CoV-2 virus are circulating, thus raising questions with respect to the effectiveness of different lines of treatment, such as vaccines and antiviral drugs.

Incidence rates of digestive cancers among U.S. military servicemen: Comparison with the rates in the general U.S. population.

Background: Digestive cancers greatly contribute to the cancer burden in the United States. These cancers are more common among men and some are increasing among adults under age 50. Military population, which is dominantly male and young, and general populations differ in exposure to risk factors for these cancers.

Impact of Age and Race on Health-Related Quality of Life Outcomes in Patients Undergoing Radical Prostatectomy for Localized Prostate Cancer.

Objectives: To investigate impact of age and race on health-related quality of life (HRQoL) in men undergoing radical prostatectomy (RP) using a prospectively maintained, racially diverse cohort.

Methods: The Center for Prostate Disease Research Multicenter National Database was used to identify patients receiving RP from 2007-2017. The Expanded PCa Index Composite and 36 Item Short-Form Health Survey were completed at baseline and regular intervals.

Survival in Pediatric, Adolescent, and Young Adult Patients With Sarcoma in the Military Health System: Comparison With the SEER Population.

Background: We sought to compare survival outcomes of sarcomas in the pediatric and adolescent/young adult populations with universal care access in the Military Health System (MHS) to those from the United States general population.

Methods: We compared data from the Department of Defense's (DoD) Automated Central Tumor Registry (ACTUR) and the National Cancer Institute's (NCI) Surveillance, Epidemiology, and End Results (SEER) program on the overall survival of patients 24 years or younger with histologically or microscopically confirmed sarcoma between diagnosed between January 1, 1987, and December 31, 2013. The Kaplan-Meier survival curves were used to compare survival between the 2 patient populations.

Racial disparities in survival among women with endometrial cancer in an equal access system.

Objective: The mortality rate for Black women with endometrial cancer (EC) is double that of White women, although the incidence rate is lower among Black women. Unequal access to care may contribute to this racial disparity. This study aimed to assess whether survival varied between non-Hispanic Black (NHB) and non-Hispanic White (NHW) women with EC in the Military Health System (MHS) which provides equal access care to its beneficiaries despite racial/ethnic background.

Clinical utility of a serum biomarker panel in distinguishing prostate cancer from benign prostate hyperplasia.

Prostate-specific antigen (PSA) screening for prostate cancer (PCa) is limited by the lack of specificity but is further complicated in the benign prostatic hyperplasia (BPH) population which also exhibit elevated PSA, representing a clear unmet need to distinguish BPH from PCa. Herein, we evaluated the utility of FLNA IP-MRM, age, and prostate volume to stratify men with BPH from those with PCa. Diagnostic performance of the biomarker panel was better than PSA alone in discriminating patients with negative biopsy from those with PCa, as well as those who have had multiple prior biopsies (AUC 0.

Cancers of Unknown Primary: A Descriptive Study in the U.S. Military Health System.

Introduction: Cancers of unknown primary (CUP) are defined as histologically confirmed metastatic cancers that do not have an identified primary site of origin despite an appropriate diagnostic workup. Although accessibility to and quality of medical care influence diagnosis of cancer including CUP, previous studies describing CUP have generally been conducted in patients with various accessibilities to care. This study aimed to describe the demographic, histologic, and temporal trend characteristics of CUP patients in the DoD Cancer Registry of the Military Health System (MHS), which provides universal health care access, reducing the potential effects of accessibility to care on research results.

Extensive three-dimensional intratumor proteomic heterogeneity revealed by multiregion sampling in high-grade serous ovarian tumor specimens.

Enriched tumor epithelium, tumor-associated stroma, and whole tissue were collected by laser microdissection from thin sections across spatially separated levels of ten high-grade serous ovarian carcinomas (HGSOCs) and analyzed by mass spectrometry, reverse phase protein arrays, and RNA sequencing. Unsupervised analyses of protein abundance data revealed independent clustering of an enriched stroma and enriched tumor epithelium, with whole tumor tissue clustering driven by overall tumor "purity." Comparing these data to previously defined prognostic HGSOC molecular subtypes revealed protein and transcript expression from tumor epithelium correlated with the differentiated subtype, whereas stromal proteins (and transcripts) correlated with the mesenchymal subtype.

Biallelic variants in KARS1 are associated with neurodevelopmental disorders and hearing loss recapitulated by the knockout zebrafish.

Purpose: Pathogenic variants in Lysyl-tRNA synthetase 1 (KARS1) have increasingly been recognized as a cause of early-onset complex neurological phenotypes. To advance the timely diagnosis of KARS1-related disorders, we sought to delineate its phenotype and generate a disease model to understand its function in vivo.

Methods: Through international collaboration, we identified 22 affected individuals from 16 unrelated families harboring biallelic likely pathogenic or pathogenic in KARS1 variants.
