Urine Metabolites as Indicators of Chronic Pain and Related Symptoms in Active-Duty Service Members: A Secondary Data Analysis of a Pragmatic Clinical Trial With SMART Design

Background Chronic pain is a major cause of distress and disability, and biomarkers may aid in the assessment and treatment of it. Urine metabolites may be valuable bioindicators that can provide biological insight regarding chronic pain. Objectives To investigate the relationship between a multimarker composite measure of metabolites and patient-reported outcomes scores in adults with chronic pain, using data from a pragmatic clinical trial with a sequential, multiple-assignment randomized trial design. Methods Self-reported measures and urine samples from 169 active-duty service members with chronic pain were collected. Urine was analyzed using a preestablished panel of metabolites, including four previously identified biomarkers of pain: kynurenic acid, pyroglutamic acid, ethylmalonic acid, and methylmalonate. Multivariable linear regression models—adjusted for participant characteristics such as age and sex—were used to cross-sectionally examine the relationship between 11 patient-reported outcomes (fatigue, sleep-related impairment, anxiety, depression, anger, pain catastrophizing, physical function, pain interference, satisfaction with participation with social roles, pain intensity, and pain impact score) and the four urine metabolites both individually and as a composite (urine metabolite pain indicator, or UMPI). Given the study’s small sample size and exploratory nature, a significance threshold of p ≤ .10 was used for all analyses. Results The UMPI showed statistically significant associations with five self-reported measures (fatigue, anxiety, depression, physical functioning, and pain impact score); adjusted Pearson correlations ranged from .18 to .25. Individual metabolite analyses supported these findings, with all relationships between individual metabolites and self-reported measures showing positive associations. Kynurenic acid and ethylmalonic acid showed the strongest associations, each having statistically significant relationships with four individual self-reported measures, while pyroglutamic acid had statistically significant relationships with three self-reported measures and methylmalonate with none. The UMPI demonstrated feasible reliability. Discussion Our finding of associations between the UMPI and components of the self-reported measures supports the development of the UMPI and these four urine metabolites as biomarkers for chronic pain outcomes. Further research is planned and will be essential for establishing mechanistic insight and guiding biomarker development within the context of pain management.

Study Protocol Evaluating Breastfeeding for Mother–Infant Dyads Experiencing Infant Ankyloglossia

Background Tongue-tie is associated with nipple pain and early breastfeeding cessation. To date, research has been limited by small sample sizes and a dearth of evidence on the effects of tongue-tie on infant feeding symptoms and physiologic breastfeeding mechanics. Objectives In this article, we describe the protocol for our study exploring infant feeding, negative breastfeeding symptoms, maternal anatomy, and physiologic sucking data between infants with and without tongue-tie. Methods A prospective cohort study design is being employed. Over 8 weeks, three visits will be conducted with a sample of mothers and their infants without tongue-tie and a sample of mothers and their infants diagnosed with tongue-tie undergoing treatment via frenotomy. The aims of the study were to compare breastfeeding symptoms, breast anatomy, infant feeding symptoms, feeding efficiency, and nutritive sucking parameters between infants with and without tongue-tie, further comparing these metrics pretreatment and posttreatment via frenotomy with the non-tongue-tied age-matched counterparts. Results This study is currently ongoing. Discussion Tongue-tie is an everyday problem; clear guidelines are needed to decide whether to treat it. This novel, innovative, and multidisciplinary research study aims to fill critical gaps in understanding the physiological and functional effects of tongue-tie on breastfeeding, offering evidence to inform better clinical decisions and support effective interventions.

Happy Family, Healthy Kids: A Healthy Eating and Stress Management Program in Low-Income Parent–Preschooler Dyads

Background Substantial effort has been invested to combat childhood obesity, but overall effects are disappointing, especially in low-income racial minority children. One possible reason is a lack of focus on the important stress–eating connection. Stress can negatively influence eating behaviors, leading to an increased appetite for high-fat and energy-dense foods. Objective This study aimed to evaluate the preliminary effects of a healthy eating and stress management program targeting multiple theoretical variables on improving eating behavior (dyads’ fruit/vegetable intake, emotional eating), food insecurity, anthropometric characteristics (dyads’ body mass index, % body fat), cardiovascular health (dyads’ blood pressure), and mental well-being (parental stress). Methods A one-group, quasi-experimental pilot study was conducted among 107 low-income parent–preschooler dyads. The 14-week program included a parent component, a parent–preschooler learning component, and a day care-based preschooler component. Results The program had positive effects on improving dyads’ fruit/vegetable intake, food insecurity, body mass index, and blood pressure and parents’ nutrition knowledge, self-efficacy, support, food resource management behavior, problem-focused coping, and home eating environment. The overall satisfaction rate was 95.2%, and 88.1% stated that the program assisted their families with having a healthy lifestyle. Discussion Results support the preliminary effects of the program on improving health outcomes in rural and urban low-income families. Although warranting further investigation with a more rigorous randomized controlled trial, the healthy eating and stress management program provides a potential solution to the current coexistence of an obesity epidemic and mental health crisis.

Tailored Nurse Support Program Promoting Positive Parenting and Family Preservation

Background Public health nurse home visiting is a promising approach for addressing the complex needs of families at risk of child maltreatment. The Colorado Nurse Support Program advances service provision by using evidence-based practices to provide tailored assessment and intervention to low-income, primiparous, and multiparous families with children under 18 years of age identified as high risk by county human service systems. Objectives This study aimed to test the effects of the Nurse Support Program on child protective services case characteristics between Nurse Support Program families and a demographically comparable reference group of families and evaluate changes in parenting outcomes from pre- to postprogram involvement for Nurse Support Program families. Methods We used a matched comparison group quasi-experimental design in which families in the Nurse Support Program (n = 48) were compared to families (n = 150) who were identified using administrative data from Colorado’s Comprehensive Child Welfare Information System. Outcomes were child protective case characteristics (child protection referrals, open assessments, founded assessments, open cases, and children’s placement in out-of-home care) and parenting outcomes. Results Nurse Support Program families were less likely to have a child protection case opened or have their child placed in out-of-home care. There were no significant between-group differences in child protection referrals, open assessments, or founded assessments. Families in the Nurse Support Program showed improvements in parenting outcomes over time. Discussion Findings suggest that the Nurse Support Program is a successful public health nurse home-visiting approach to promote positive parenting and family preservation among families with complex needs. Implementing tailored public health nurse home-visiting programs, such as the Nurse Support Program, should continue to be evaluated and supported to mitigate the public health risk of child maltreatment.

An Evaluation of the Multifactorial Model of Cancer-Related Cognitive Impairment

Background Up to 45% of patients report cancer-related cognitive impairment (CRCI). A variety of characteristics are associated with the occurrence and/or severity of CRCI. However, an important gap in knowledge of risk factors for CRCI is the relative contribution of each factor. The multifactorial model of cancer-related cognitive impairment (MMCRCI) is a conceptual model of CRCI that can be used to evaluate the strength of relationships between various factors and CRCI. Objectives The purpose of this study was to use structural regression methods to evaluate the MMCRCI using data from a large sample of outpatients receiving chemotherapy (n = 1,343). Specifically, the relationships between self-reported CRCI and four MMCRCI concepts (i.e., social determinants of health, patient-specific factors, treatment factors, and co-occurring symptoms) were examined. The goals were to determine how well the four concepts predicted CRCI and determine the relative contribution of each concept to deficits in perceived cognitive function. Methods This study is part of a larger, longitudinal study that evaluated the symptom experience of oncology outpatients receiving chemotherapy. Adult patients were diagnosed with breast, gastrointestinal, gynecological, or lung cancer; had received chemotherapy within the preceding 4 weeks; were scheduled to receive at least two additional cycles of chemotherapy; were able to read, write, and understand English; and gave written informed consent. Self-reported CRCI was assessed using the attentional function index. Available study data were used to define the latent variables. Results On average, patients were 57 years of age, college educated, and with a mean Karnofsky Performance Status score of 80. Of the four concepts evaluated, whereas co-occurring symptoms explained the largest amount of variance in CRCI, treatment factors explained the smallest amount of variance. A simultaneous structural regression model that estimated the joint effect of the four exogenous latent variables on the CRCI latent variable was not significant. Discussion These findings suggest that testing individual components of the MMCRCI may provide useful information on the relationships among various risk factors, as well as refinements of the model. In terms of risk factors for CRCI, co-occurring symptoms may be more significant than treatment factors, patient-specific factors, and/or social determinants of health in patients receiving chemotherapy.
