Pan-cancer secreted proteome and skeletal muscle regulation: insight from a proteogenomic data-driven knowledge base.

Large-scale, pan-cancer analysis is enabled by data driven knowledge bases that link tumor molecular profiles with phenotypes. A debilitating cancer-related phenotype is skeletal muscle loss, or cachexia, which occurs partly from tumor products secreted into circulation. Using the LinkedOmicsKB knowledge base assembled from the Clinical Proteomics Tumor Analysis Consortium proteogenomic analysis, along with catalogs of human secretome proteins, ligand-receptor pairs and molecular signatures, we sought to identify candidate pan-cancer proteins secreted to blood that could regulate skeletal muscle phenotypes in multiple solid cancers.

Increasing the Use of Newborn Pain Treatment Following the Implementation of a Parent-Targeted Video: An Outcome Evaluation.

Background/objectives: Despite strong evidence that breastfeeding, skin-to-skin care, and sucrose reduce pain in newborns during minor painful procedures, these interventions remain underutilized in practice. To address this knowledge-to-practice gap, we produced a five-minute parent-targeted video demonstrating the analgesic effects of these strategies and examined whether the use of newborn pain treatment increased in maternal-newborn care settings following the introduction of the video by nurses.

Methods: The design was a pre-post outcome evaluation.

The bioenergetic landscape of cancer.

Background: Bioenergetic remodeling of core energy metabolism is essential to the initiation, survival, and progression of cancer cells through exergonic supply of adenosine triphosphate (ATP) and metabolic intermediates, as well as control of redox homeostasis. Mitochondria are evolutionarily conserved organelles that mediate cell survival by conferring energetic plasticity and adaptive potential. Mitochondrial ATP synthesis is coupled to the oxidation of a variety of substrates generated through diverse metabolic pathways.

Impact of Pretreatment Weight Loss on Radiotherapy Utilization and Clinical Outcomes in Non-Small Cell Lung Cancer.

Background: Cancer cachexia is a syndrome of unintentional weight loss resulting in progressive functional impairment. Knowledge of radiation therapy utilization in patients with cancer cachexia is limited. We evaluated the use of curative and palliative-intent radiation for the management of patients with non-small cell lung cancer (NSCLC) with cachexia to determine whether tumor-directed therapy affected cachexia-associated outcomes.

The Parenting Sense of Competence scale: Updating a classic.

Background: The Parenting Sense of Competence (PSOC) is a self-report measure of parenting efficacy and satisfaction that is widely used by researchers and clinicians in many countries. Despite its popularity, there have been some criticisms of the instrument. The aims of the current study were to identify and address shortcomings of the PSOC and to produce a revised measure that reflected the original constructs and that demonstrated robust psychometric properties.

The impacts of typically developing siblings on the developmental outcomes of children with disability: A scoping review.

Background: Siblings represent an important influence on children's development. It is possible that sibling influence on developmental outcomes differs in sibling pairs when one of the children has a disability. Previous research has tended to focus on outcomes for typically developing siblings when they have a brother/sister with a disability.

Exploring implementation processes of a parent-targeted educational video for improving newborn pain treatment: A sequential exploratory mixed-methods study.

Despite known analgesic effects of breastfeeding (BF), skin-to-skin care (SSC), and sweet solutions (sucrose) for newborns, these interventions remain underutilized. Our team produced a five-minute parent-targeted video (BSweet2Babies) demonstrating BF, SSC, and sucrose during newborn blood sampling. We conducted a sequential exploratory mixed-methods study with eight maternal-newborn units across Ontario, Canada to identify barriers and facilitators to implementing the video and the three pain management strategies.

Skeletal muscle omics signatures in cancer cachexia: perspectives and opportunities.

Cachexia is a life-threatening complication of cancer that occurs in up to 80% of patients with advanced cancer. Cachexia reflects the systemic consequences of cancer and prominently features unintended weight loss and skeletal muscle wasting. Cachexia impairs cancer treatment tolerance, lowers quality of life, and contributes to cancer-related mortality.

Race, Ethnicity, and Socioeconomic Factors as Determinants of Cachexia Incidence and Outcomes in a Retrospective Cohort of Patients With Gastrointestinal Tract Cancer.

Purpose: Cachexia is a paraneoplastic syndrome of unintentional adipose and muscle tissue wasting with severe impacts to functionality and quality of life. Although health inequities across minority and socioeconomically disadvantaged groups are known, the role of these factors in cachexia progression is poorly characterized. This study aims to evaluate the relationship between these determinants and cachexia incidence and survival in patients with gastrointestinal tract cancer.

Racial, Ethnic, and Socioeconomic Characteristics Independently Predict for Cachexia Risk and Associated Survival Outcomes in Stage IV NSCLC: A Brief Report.

Introduction: Cancer cachexia, found in more than a third of patients with NSCLC, directly leads to functional and survival detriments. As screening and interventions for cachexia and NSCLC improve, deficits in health care access and quality among patients disadvantaged by racial-ethnic and socioeconomic factors must be addressed.

Methods: We retrospectively evaluated 957 patients diagnosed with having stage IV NSCLC between 2014 and 2020 in Dallas, Texas.

Factors related to parenting styles of Chinese mothers of children with and without intellectual disability.

Background: Parenting styles play a crucial role in children's development. However, approaches to parenting children with intellectual disability (ID) beyond Western cultures have been underexamined. This study compared the self-reported parenting styles of Chinese mothers of children with and without ID and examined some factors that might be related.

A preponderance of gastrointestinal cancer patients transition into cachexia syndrome.

Background: Cancer cachexia is frequently documented by self-reported, single time-point weight histories. This approach lacks the granularity needed to fully elucidate the progression of cachexia syndrome. This study aimed to longitudinally assess body weight changes pre- and post-cancer diagnosis in gastrointestinal (GI) cancer patients.

Infant Feeding Varies Across Eating Behavior and Feeding Modalities in Mothers With Low Income.

Objective: To examine if eating behaviors in mothers with low income relate to attitudes toward infant feeding and whether associations differed between breastfeeding and formula-feeding mothers.

Design: Cross-sectional study.

Participants: Forty postpartum women (aged ≥ 18 years, body mass index ≥ 25 and < 40 kg/m²) in the Louisiana Women, Infants, and Children program participated in a telehealth postpartum intervention for health and weight loss.

Evaluation of the Efficacy of a Hypoglycemia Protocol to Treat Severe Hypoglycemia.

Purpose: The purpose of this quality improvement project was to evaluate the efficacy of the facility's Hypoglycemia Protocol when treating severe hypoglycemia (defined as blood glucose < 50 mg/dL).

Description: The diabetes clinical nurse specialists conducted a retrospective chart review of diabetic inpatients with severe hypoglycemia who were treated per the Hypoglycemia Protocol from October 1, 2017, through April 30, 2019. The primary outcome was achievement of euglycemia (defined as blood glucose ≥ 80 mg/dL) 15 to 30 minutes post treatment with either oral carbohydrates or intravenous dextrose.

Breast cancer growth and proliferation is suppressed by the mitochondrial targeted furazano[3,4-b]pyrazine BAM15.

Background: Enhanced metabolic plasticity and diversification of energy production is a hallmark of highly proliferative breast cancers. This contributes to poor pharmacotherapy efficacy, recurrence, and metastases. We have previously identified a mitochondrial-targeted furazano[3,4-b]pyrazine named BAM15 that selectively reduces bioenergetic coupling efficiency and is orally available.

Moringa Oleifera Seed Extract Concomitantly Supplemented with Chemotherapy Worsens Tumor Progression in Mice with Triple Negative Breast Cancer and Obesity.

Triple negative breast cancer (TNBC) is an aggressive and highly metastatic breast cancer subtype with limited treatment options. Obesity and insulin resistance are associated with a worse prognosis in those with TNBC. Moringa oleifera (moringa) is a tropical edible plant used for both food and medicinal purposes and found to have anti-obesity and anti-cancer effects in vitro and in preclinical models.

Analytical Determination of Mitochondrial Function of Excised Solid Tumor Homogenates.

Mitochondria are essential to the onset and progression of cancer through energy production, reactive oxygen species regulation, and macromolecule synthesis. Genetic and functional adaptations of mitochondria to the tumor environment drive proliferative and metastatic potential. The advent of DNA and RNA sequencing removed critical barriers to the evaluation of genetic mediators of tumorigenesis.

Obesity-Associated Myeloid Immunosuppressive Cells, Key Players in Cancer Risk and Response to Immunotherapy.

Obesity is a risk factor for developing several cancers. The dysfunctional metabolism and chronic activation of inflammatory pathways in obesity create a milieu that supports tumor initiation, progression, and metastasis. Obesity-associated metabolic, endocrine, and inflammatory mediators, besides interacting with cells leading to a malignant transformation, also modify the intrinsic metabolic and functional characteristics of immune myeloid cells.
