Distress and inflammation are independently associated with cancer-related symptom severity.

Objective: To evaluate longitudinal associations of distress and inflammation with somatic and depressive symptom severity in breast cancer patients, from before to six months after neoadjuvant chemotherapy. We also explored feasibility and effects of an early mindfulness-based intervention for preventing or reducing somatic and depressive symptoms.

Methods: Longitudinal pilot study with a randomized waitlist-controlled intervention design.

A Qualitative Study of the Knowledge of Metabolic Syndrome, Attitudes about Lifestyle Modifications, and Preferences for Lifestyle Interventions among Patients with Cancer and Metabolic Syndrome.

Metabolic syndrome is a group of disorders-hypertension, dyslipidemia, obesity, and insulin resistance-that together increase the risk of coronary heart disease, stroke, and diabetes. Although ~60% of cancer patients have metabolic syndrome, which increases their risk of mortality, oncology providers lack clear guidance about its management. The development of metabolic syndrome lifestyle interventions requires a better understanding of these patients' knowledge, attitudes, and intervention preferences in order to inform management.

Development of a PROMIS multidimensional cancer-related fatigue (mCRF) form using modern psychometric techniques.

Purpose: To develop a PRO assessment of multidimensional cancer-related fatigue based on the PROMIS fatigue assessments.

Method: Cancer patients reporting fatigue were recruited from a comprehensive cancer care center and completed a survey including 39 items from the PROMIS Cancer Item Bank-Fatigue. Component and factor structures of the fatigue items were explored with Monte Carlo parallel factor and Mokken analyses, respectively.

A Qualitative Study of Knowledge of Metabolic Syndrome, Attitudes about Lifestyle Modifications, and Preferences for Lifestyle Interventions among Patients with Cancer and Metabolic Syndrome.

Background: Nearly 60% of patients with cancer have metabolic syndrome, which increases the risk of mortality, but there is no clear guidance for oncology providers about its management. Here, we report on the qualitative component of a larger mixed methods study that aimed to understand cancer patients' knowledge, attitudes, and preferences regarding metabolic syndrome.

Methods: Adult cancer patients with metabolic syndrome were recruited during 2022-2023 in the MD Anderson General Internal Medicine clinic and participated in semistructured interviews focused on metabolic syndrome and lifestyle interventions.

A detailed description of the distress trajectory from pre- to post-treatment in breast cancer patients receiving neoadjuvant chemotherapy.

Purpose: To characterize the distress trajectory in patients with newly diagnosed, non-metastatic breast cancer from pre-neoadjuvant chemotherapy until 12 months after onset of treatment and to identify demographic and clinical predictors of distress in these patients.

Methods: In a retrospective, longitudinal study, chart review data were abstracted for 252 eligible patients treated at a comprehensive cancer care center. The center screens for distress at least monthly with the distress thermometer; the highest distress score per month was included in the analyses.

Associations between fatigue and cellular metabolism in breast cancer patients: A longitudinal study.

Purpose: Fatigue is frequently experienced during treatment for cancer and persists for months to years after treatment completion in a subset of patients. The underlying mechanisms remain poorly understood. We postulated that reduced cellular energy metabolism may underlie fatigue in cancer patients and survivors and tested this hypothesis in a sample of patients newly diagnosed with early-stage breast cancer (n = 49) followed for approximately 1 year from before the start of neoadjuvant chemotherapy (NACT) till after treatment completion.

A central role for apathy in the effectiveness of interventions for cancer-related fatigue.

Objective: Cancer-related fatigue (CRF) affects a substantial number of cancer patients and survivors. Recommendations for CRF treatments are largely based on results of randomized controlled trials. The interpretability of such results is limited to patients eligible and willing to participate in these trials.

Clinical relevance of a Body Image Scale cut point of 10 as an indicator of psychological distress in cancer patients: results from a psychiatric oncology clinic.

Purpose: Adequate adjustment to bodily changes during various phases of cancer treatment is important to patients' emotional well-being. The Body Image Scale (BIS) is a widely used tool for assessment of body image concerns in different cancer types. However, a cut point score indicative of clinically relevant body image concerns has not been established.

Patient-reported fatigue prior to treatment is prognostic of survival in patients with acute myeloid leukemia.

Acute myeloid leukemia (AML) is associated with poor survival. While clinical prognostic factors of survival have been identified, the contribution of patient-reported symptoms has only received marginal attention. Fatigue is one of the most commonly reported symptoms of AML.

An effort expenditure perspective on cancer-related fatigue.

While fatigue is the most common and debilitating side effect of cancer and cancer treatment it is still poorly understood, partly because it is usually characterized by patient-reported outcomes. As patient-reports are inherently subjective, behavioral correlates of the symptom of fatigue are needed to increase our understanding of the symptom. We focused on motivational effort expenditure as a crucial behavior in cancer-related fatigue, using a validated computerized task contrasting high effort/high reward and low effort/low reward choices under different probabilities of success.

Experimental pressure-pain assessments: Test-retest reliability, convergence and dimensionality.

Introduction Experimental pain studies can provide unique insight into the dimensions of pain and into individual differences in pain responsiveness by controlling different aspects of pain-eliciting stimuli and pain measures. In experimental pain studies, pain responsiveness can be assessed as pain threshold, pain tolerance or pain ratings. The test-theoretical qualities of these different measures, however, have not yet been completely documented.

The High Costs of Low-Grade Inflammation: Persistent Fatigue as a Consequence of Reduced Cellular-Energy Availability and Non-adaptive Energy Expenditure.

Chronic or persistent fatigue is a common, debilitating symptom of several diseases. Persistent fatigue has been associated with low-grade inflammation in several models of fatigue, including cancer-related fatigue and chronic fatigue syndrome. However, it is unclear how low-grade inflammation leads to the experience of fatigue.

Associations of inflammation with symptom burden in patients with acute myeloid leukemia.

The aim of the study was to assess the association inflammation with symptom burden in patients with acute myeloid leukemia (AML), assessed before and during remission induction chemotherapy (IC). Patients with AML (n = 95) were followed from baseline (before IC) to the third week of IC for severity of self-reported somatic symptoms (assessed with the MD Anderson Symptom Inventory) and plasma levels of 13 inflammation-related biomarkers (n = 64). A composite symptom burden severity score was computed as the average score of the six most severe somatic symptoms i.

Mechanisms of Neurotoxic Symptoms as a Result of Breast Cancer and Its Treatment: Considerations on the Contribution of Stress, Inflammation, and Cellular Bioenergetics.

Purpose Of Review: Breast cancer and its treatment are associated with a range of neurotoxic symptoms, such as fatigue, cognitive impairment, and pain. Although these symptoms generally subside after treatment completion, they become chronic in a significant subset of patients. We here summarize recent findings on neuroinflammation, stress, and mitochondrial dysfunction as mechanistic pathways leading to neurotoxic symptom experience in breast cancer patients and survivors.

Lipopolysaccharide Alters Motivated Behavior in a Monetary Reward Task: a Randomized Trial.

Inflammation-induced sickness is associated with a large set of behavioral alterations; however, its motivational aspects remain poorly explored in humans. The present study assessed the effect of lipopolysaccharide (LPS) administration at a dose of 2 ng/kg of body weight on motivation in 21 healthy human subjects in a double-blinded, placebo (saline)-controlled, cross-over design. Incentive motivation and reward sensitivity were measured using the Effort Expenditure for Rewards Task (EEfRT), in which motivation for high-effort/high-reward trials vs low-effort/low-reward trials are manipulated by variations in reward magnitude and probability to win.

Executive functioning and diabetes: The role of anxious arousal and inflammation.

Individuals who perform poorly on measures of the executive function of inhibition have higher anxious arousal in comparison to those with better performance. High anxious arousal is associated with a pro-inflammatory response. Chronically high anxious arousal and inflammation increase one's risk of developing type 2 diabetes.

Mechanisms of chemotherapy-induced behavioral toxicities.

While chemotherapeutic agents have yielded relative success in the treatment of cancer, patients are often plagued with unwanted and even debilitating side-effects from the treatment which can lead to dose reduction or even cessation of treatment. Common side effects (symptoms) of chemotherapy include (i) cognitive deficiencies such as problems with attention, memory and executive functioning; (ii) fatigue and motivational deficit; and (iii) neuropathy. These symptoms often develop during treatment but can remain even after cessation of chemotherapy, severely impacting long-term quality of life.

Infection load as a predisposing factor for somatoform disorders: evidence from a Dutch General Practice Registry.

Objective: Somatoform disorders (SDs) are characterized by chronic multiple functional somatic (FS) symptoms. It has been suggested that infections may be triggers for FS symptoms to occur, pointing to the immune system as a pathogenic factor in their development. The current study aimed to compare the prevalence of infections (i.
