Patient-reported functional outcomes and treatment-related regret in Hispanic and Spanish-speaking men following prostate cancer treatment.

Objectives: Compare functional outcomes and treatment-related regret over 10 years in Spanish- and English-speaking Hispanic men compared to non-Hispanic men following treatment of localized prostate cancer.

Methods And Materials: Data from a prospective cohort study of men with localized prostate cancer treated with active surveillance, radical prostatectomy or radiotherapy were used to examine the effect of survey language (Spanish speaking vs. English speaking) and ethnicity (Hispanic vs.

Association between smoking and prostate cancer survivors' long-term quality of life and function: an analysis of the CEASAR (Comparative Effectiveness Analysis of Surgery and Radiation) study.

Purpose: There is limited evidence of tobacco smoking's effect on cancer survivors' quality of life (QOL) and function. As the natural history of localized prostate cancer (PCa) is protracted, there is a need to identify modifiable risk factors that can influence PCa survivorship, such as tobacco smoking.

Material And Methods: We used up to 10-year survey data from the CEASAR (Comparative Effectiveness Analysis of Surgery and Radiation) study, a prospective, population-based, observational study of patients diagnosed with localized PCa in 2011-2012.

Personalized brain circuit scores identify clinically distinct biotypes in depression and anxiety.

There is an urgent need to derive quantitative measures based on coherent neurobiological dysfunctions or 'biotypes' to enable stratification of patients with depression and anxiety. We used task-free and task-evoked data from a standardized functional magnetic resonance imaging protocol conducted across multiple studies in patients with depression and anxiety when treatment free (n = 801) and after randomization to pharmacotherapy or behavioral therapy (n = 250). From these patients, we derived personalized and interpretable scores of brain circuit dysfunction grounded in a theoretical taxonomy.

Dynamic stem-loop extension by Pol θ and templated insertion during DNA repair.

Theta-mediated end joining (TMEJ) is critical for survival of cancer cells when other DNA double-stranded break repair pathways are impaired. Human DNA polymerase theta (Pol θ) can extend ssDNA oligonucleotides, but little is known about preferred substrates and mechanism. We show that Pol θ can extend both ssDNA and RNA substrates by unimolecular stem-loop synthesis initiated by only two 3' terminal base pairs.

Probiotic DSM 17938 Changes Foxp3 Deficiency-Induced Dyslipidemia and Chronic Hepatitis in Mice.

The probiotic DSM 17938 produces anti-inflammatory effects in scurfy (SF) mice, a model characterized by immune dysregulation, polyendocrinopathy, enteropathy, and X-linked inheritance (called IPEX syndrome in humans), caused by regulatory T cell (Treg) deficiency and is due to a Foxp3 gene mutation. Considering the pivotal role of lipids in autoimmune inflammatory processes, we investigated alterations in the relative abundance of lipid profiles in SF mice (± treatment with DSM 17938) compared to normal WT mice. We also examined the correlation between plasma lipids and gut microbiota and circulating inflammatory markers.

Carotid Plaque-RADS: A Novel Stroke Risk Classification System.

Background: Carotid artery atherosclerosis is highly prevalent in the general population and is a well-established risk factor for acute ischemic stroke. Although the morphological characteristics of vulnerable plaques are well recognized, there is a lack of consensus in reporting and interpreting carotid plaque features.

Objectives: The aim of this paper is to establish a consistent and comprehensive approach for imaging and reporting carotid plaque by introducing the Plaque-RADS (Reporting and Data System) score.

Analysis and prediction of liver volume change maps derived from computational tomography scans acquired pre- and post-radiation therapy.

External beam radiation therapy (EBRT) of liver cancers can cause local liver atrophy as a result of tissue damage or hypertrophy as a result of liver regeneration. Predicting those volumetric changes would enable new strategies for liver function preservation during treatment planning. However, understanding of the spatial dose/volume relationship is still limited.

Errol Friedberg: A life in writing.

Errol Clive Friedberg, who died at the end of March 2023, was the first Editor-in-Chief of the journal DNA Repair. He was an influential DNA repair scientist, a synthesizer of ideas, and an accomplished historian. In addition to the research accomplishments of his laboratory groups, Errol Friedberg provided enormous service to the DNA repair community though organizing major conferences, journal editing, and writing.

Expert Consensus Statement: Management of Dysphagia in Head and Neck Cancer Patients.

Objective: To develop an expert consensus statement (ECS) on the management of dysphagia in head and neck cancer (HNC) patients to address controversies and offer opportunities for quality improvement. Dysphagia in HNC was defined as swallowing impairment in patients with cancers of the nasal cavity, paranasal sinuses, nasopharynx, oral cavity, oropharynx, larynx, or hypopharynx.

Methods: Development group members with expertise in dysphagia followed established guidelines for developing ECS.

Association between body mass index and localized prostate cancer management and disease-specific quality of life.

Purpose: The purpose of this work is to describe the association between body mass index (BMI) and (1) management option for localized prostate cancer (PCa) and (2) disease-specific quality of life (ds-QoL) after treatment or active surveillance.

Subjects/patients And Methods: We analysed data from men with localized PCa managed with radical prostatectomy (RP), radiation therapy (RT), or active surveillance (AS) in a prospective, population-based cohort study. We evaluated the association between BMI and management option with multivariable multinomial logistic regression analysis.

Genome Protection by DNA Polymerase θ.

DNA polymerase θ (Pol θ) is a DNA repair enzyme widely conserved in animals and plants. Pol θ uses short DNA sequence homologies to initiate repair of double-strand breaks by theta-mediated end joining. The DNA polymerase domain of Pol θ is at the C terminus and is connected to an N-terminal DNA helicase-like domain by a central linker.

NMR Spectroscopy-Based Metabolomics of Platelets to Analyze Brain Tumors.

"Tumor-educated platelets" have recently generated substantial interest for the diagnosis of cancer. We hypothesized that tumor educated platelets from patients with brain tumors will reflect altered metabolism compared to platelets from healthy volunteers. Here, in a pilot study, we have employed nuclear magnetic resonance (NMR) spectroscopy in platelets from brain tumor patients to demonstrate altered metabolism compared to the platelets obtained from healthy volunteers.

Probing the structure and function of polymerase θ helicase-like domain.

DNA Polymerase θ is the key actuator of the recently identified double-strand break repair pathway, theta-mediated end joining (TMEJ). It is the only known polymerase to have a 3-domain architecture containing an independently functional family A DNA polymerase tethered by a long central region to an N-terminal helicase-like domain (HLD). Full-length polymerase θ and the isolated HLD hydrolyze ATP in the presence of DNA, but no processive DNA duplex unwinding has been observed.

When DNA Polymerases Multitask: Functions Beyond Nucleotidyl Transfer.

DNA polymerases catalyze nucleotidyl transfer, the central reaction in synthesis of DNA polynucleotide chains. They function not only in DNA replication, but also in diverse aspects of DNA repair and recombination. Some DNA polymerases can perform translesion DNA synthesis, facilitating damage tolerance and leading to mutagenesis.

This first-in-human study was designed to determine the safety and pharmacokinetics of BAY1436032, and to evaluate its potential pharmacodynamics and antitumor effects.

Patients And Methods: The study comprised of dose escalation and dose expansion cohorts.

Immunotherapy in Gastrointestinal Malignancies.

Gastrointestinal (GI) cancers represent a variety of malignancies, each with a unique interplay between the tumor and local immune microenvironment. The successes that immunotherapy, particularly immune checkpoint inhibition, has brought to various other solid tumors have largely not yielded the same benefits to patients with GI cancers. There are subsets of patients for whom immunotherapy has been FDA approved in recent years.

Woolly Monkey-HBV Infection in Squirrel Monkeys as a Surrogate Nonhuman Primate Model of HBV Infection.

Development of curative therapies for chronic hepatitis B virus (HBV) infection will likely require new animal models. Here, we evaluate HBV infection in squirrel monkeys based on the high-sequence homology of the HBV receptor, Na+/taurocholate co-transporting peptide (NTCP), between humans and squirrel monkeys. HBV PreS1 peptide was examined for binding human and squirrel monkey NTCP.
