Background: Although common, the severity of the psychological symptom cluster (PSC) (ie, co-occurrence of anxiety, depression, fatigue, sleep disturbance) varies among women with breast cancer. In addition, the impact of various types of stress and other risk factors on its severity are understudied, and the influence of the PSC on quality of life (QOL) outcomes remains poorly characterized.
Objective: To identify subgroups of postmenopausal women with breast cancer with distinct PSC severity profiles following surgery and evaluate whether these subgroups differed in terms of demographic and clinical characteristics, symptoms, social and posttraumatic stress, and QOL.
Background: Approximately one-third of breast cancer (BC) patients show poorer cognitive function (CF) before receiving adjuvant therapy compared with age-matched healthy controls. However, the biological mechanisms driving CF variation in the context of BC remain unclear. In this study, we aimed to identify genes and biological pathways associated with CF in postmenopausal women with early-stage hormone receptor-positive (HR+) BC using DNA methylation (DNAm) data, a dynamic regulator of gene activity.

Background: Cancer-related cognitive impairment (CRCI) is reported by 45% of patients with cancer. Significant gaps in knowledge remain regarding the mechanisms that underlie CRCI.
Objectives: Using a data-driven approach, the study purpose was to evaluate for perturbed pathways associated with membership in the High versus the Low CRCI profiles.
Cancer-related cognitive impairment (CRCI) is a broad term encompassing subtle cognitive problems to more severe impairment. CRCI severity is influenced by host, disease, and treatment factors and affects patients prior to, during, and following cancer treatment. The National Cancer Institute (NCI) Symptom Management and Health-Related Quality of Life Steering Committee (SxQoL SC) convened a Clinical Trial Planning Meeting (CTPM) to review the state of the science on CRCI and to develop both Phase II/III intervention trials aimed at improving cognitive function in cancer survivors with non-central nervous system (CNS) disease and longitudinal studies to understand the trajectory of cognitive impairment and contributing factors.

Study purposes were to identify subgroups of patients with distinct morning energy profiles; evaluate for differences among the profiles in demographic and clinical characteristics, as well as measures of stress, resilience, and coping.
Methods: A total of 1,343 outpatients receiving chemotherapy completed a demographic questionnaire and measures of global, cancer-related, and cumulative life stress, and resilience at study enrollment.
Objectives: Shortness of breath is a common symptom in patients with cancer. However, the mechanisms that underlie this troublesome symptom are poorly understood. Therefore, this study aimed to determine the prevalence of and associated risk factors for shortness of breath in women prior to breast cancer surgery and identify associations between shortness of breath and polymorphisms for potassium channel genes.

Objective: To examine interindividual variations in trajectories of depressive symptoms during 2 cycles of chemotherapy and to evaluate associations between demographic and clinical characteristics, symptom severity scores, psychological adjustment characteristics (eg, stress and coping), and initial levels and trajectories of depressive symptoms.
Methods: Patients (n = 1323) diagnosed with breast, gynecologic, lung, or gastrointestinal cancer completed the Center for Epidemiological Studies-Depression Scale 6 times, over 2 cycles of chemotherapy.
Management of severe traumatic brain injury (sTBI) typically involves the use of sedation, which inherently results in benefits and risks. The cytochrome P450 enzyme CYP2B6 is involved in the biotransformation of particular drug classes, including many intravenous sedatives. Variants of the gene can lead to decreased systemic clearance of some sedatives, including propofol.

Sample & Setting: Postmenopausal women (N = 116) with early-stage hormone receptor-positive breast cancer were recruited from western Pennsylvania.
Methods & Variables: Candidate genes from the Nrf2-ARE pathway were investigated for associations with CRF occurrence and severity.
Objectives: To determine associations among DNA methylation of brain-derived neurotrophic factor (BDNF) and RAS p21 protein activator 2 (RASA2) genes with processing speed and perceived cognitive function.
Sample & Setting: This was a cross-sectional, secondary analysis of baseline data from a randomized controlled trial, the Exercise Program in Cancer and Cognition Study.
Methods & Variables: Data included M values for DNA methylation of the BDNF and RASA2 genes; processing speed, objectively measured using the Grooved Pegboard and Digit Vigilance Test scores; and perceived cognitive function, self-reported using the Patient Assessment of Own Functioning Inventory.
Objectives: To evaluate for associations between the occurrence of palpitations reported by women prior to breast cancer surgery and single nucleotide polymorphisms (SNPs) for neurotransmitter genes.
Sample & Setting: A total of 398 women, who were scheduled for unilateral breast cancer surgery, provided detailed information on demographic and clinical characteristics and the occurrence of palpitations prior to breast cancer surgery.
Methods & Variables: The occurrence of palpitations was assessed using a single item (i.
Objectives: To identify subgroups of patients with distinct cough occurrence profiles and evaluate for differences among these subgroups.
Sample & Setting: Outpatients receiving chemotherapy (N = 1,338) completed questionnaires six times over two chemotherapy cycles.
Methods & Variables: Occurrence of cough was assessed using the Memorial Symptom Assessment Scale.
Objective: The Exercise Program in Cancer and Cognition (EPICC) Study was a randomized controlled trial (RCT) designed to determine whether six months of moderate-intensity aerobic exercise improves neurocognitive function in women with breast cancer (BC) receiving endocrine therapy (ET).
Methods: Postmenopausal women with hormone receptor+, early-stage BC, within two years post-primary therapy were randomized to the exercise intervention (six months, ≥150 minutes of moderate-intensity aerobic exercise/week) or usual care control condition. Outcomes were assessed at pre-randomization and after intervention completion.
Inflammation contributes to disparate neurodevelopmental outcomes between preterm and term-born infants. In this context, DNA methylation may contribute to inflammation by affecting gene expression. Brain-derived neurotrophic factor () and nuclear factor-kappa-B-inhibitor alpha () are important genes for targeted DNA methylation analysis.

Sample & Setting: Patients (N = 1,331) receiving chemotherapy were recruited from outpatient oncology clinics.
Methods & Variables: Measures of global, cancer-specific, and cumulative life stress, resilience, and coping were obtained.
Purpose: Lumbar spinal stenosis (LSS) is common in our aging population resulting in pain and functional impairment. Recent advances in pain research have identified several single nucleotide polymorphisms (SNP) associated with inter-individual symptom and treatment response. The goal of the current study was to investigate the association of SNPs in Neuropeptide Y (NPY) and Catechol-O-methyltransferase (COMT) with pain, function, and treatment outcomes in Lumbar spinal stenosis (LSS) patients receiving non-surgical treatments.
