BackgroundComplete blood count (CBC) is a commonly used and cost-effective blood test in health screenings; however, its potential as a biomarker for early detection of chronic diseases remains underutilized. Previous studies have shown that the neutrophil-to-lymphocyte ratio (NLR) is associated with systemic inflammation and is correlated with cardiometabolic diseases (CMDs). Unhealthy lifestyles can trigger inflammatory responses and contribute to the progression of CMDs. This study aimed to explore the association between NLR levels, cardiometabolic risks, and health-related behaviors.MethodsA community-based, cross-sectional study was conducted in collaboration with a local hospital as part of an annual health screening for rural adults. The study outcomes included CMDs, health-related behaviors, and NLR levels. A multivariable quantile regression model, adjusted for confounding factors, was used to identify factors associated with NLR levels.ResultsA total of 11,220 participants were enrolled. CMDs prevalence was 25.8%, with hypertension and diabetes being most common. Nearly half of participants reported insufficient exercise, low water intake, and inadequate oral hygiene. Higher NLR was significantly associated with CMDs (p for trend <0.001). Older age (p < .01) and living alone (p < .01) were linked to higher NLR, while adequate water intake (p < .05) and regular exercise (p < .01) were associated with lower NLR levels.ConclusionsRural adults demonstrated a high prevalence of CMDs and inadequate health-related behaviors, which were associated with elevated NLR levels. Implementing NLR-guided lifestyle modifications and tailored health promotion programs may serve as innovative strategies to mitigate the progression of CMDs.

Background: Functional training is increasingly recognized for its potential to improve physical function and quality of life (QoL) in older adults. This randomized controlled trial examined the effects of a six-week functional training program on physical function, cardiorespiratory fitness, and QoL in older women. Methods: Fifty older women (mean age: 63.5 ± 3.7 years) were randomly assigned to a functional training group (n = 25) or a control group (n = 25). The intervention group participated in a six-week functional training program (six sessions per week), while the control group maintained usual daily activities. Outcomes included dynamic balance (TUG test), flexibility, muscle strength, walking speed, cardiorespiratory fitness (two-minute step test), and QoL. Results: Functional training significantly improved dynamic balance, lower body flexibility, lower body strength, walking speed, and aerobic endurance (p < .05 for all). QoL significantly increased in the functional training group across all domains, as well as overall scores (p < .05). However, the control group experienced declines in some measures. Conclusion: Functional training is a safe and effective intervention for improving physical function, cardiorespiratory fitness, and QoL in older women. The significant enhancements in physical and mental health highlight its value in promoting independence and well-being in aging populations. Future studies should explore its long-term benefits and scalability.

Background: Glycemic variability and its management hold significant prognostic implications in clinical practice for patient outcomes. The aim of this study is to analyze the correlation between glycemic variability and the deterioration of neurological function in patients with intracerebral hemorrhage (ICH), to provide evidence-based support for the treatment and care of clinical ICH patients. Methods: Patients with ICH admitted to our hospital between January 2022 and August 2024 were subjected to the National Institutes of Health Stroke Scale (NIHSS) scoring upon admission and discharge. A comparative analysis of baseline characteristics and glycemic variability parameters was conducted. Results: A total of 156 patients with ICH were included. The incidence of neurological deterioration in ICH patients was 30.8%. Correlation analysis revealed significant associations between age (r = 0.602), mean glucose levels (r = 0.623), Time in Range (TIR) (r = 0.589), Mean Amplitude of Glycemic Excursions (MAGE) (r = 0.608), and Large Amplitude of Glycemic Excursions (LAGE) (r = 0.634) with the occurrence of neurological deterioration. Logistic regression analysis identified age (OR = 2.512, 95%CI: 1.924-3.006), mean glucose (OR = 2.743, 95%CI: 2.101-3.286), TIR (OR = 3.204, 95%CI: 2.985-3.607), MAGE (OR = 3.029, 95%CI: 2.601-3.748), and LAGE (OR = 2.768, 95%CI: 2.245-3.103) as significant predictors of neurological deterioration in ICH patients. Conclusion: This finding underscores the critical importance of considering both chronological age and glycemic control metrics in the prognostic evaluation of ICH patients. Integrating these factors into clinical assessments may enhance the accuracy of predicting patient outcomes and guide tailored therapeutic strategies.

In this study, we aimed to investigate if the pace of biological aging serves as a critical mediator in the relationship between chronic pain resilience and chronic low back pain intensity and disability. Two hundred seven community-dwelling non-Hispanic Black (NHB) and non-Hispanic White (NHW) adults completed the Pain Resilience Scale (PRS) and Graded Chronic Pain Scale (GCPS). Blood genomic DNA was sequenced using Illumina's MethylationEPIC, and the pace of biological aging estimated using the DunedinPACE (the Dunedin Pace of Aging Calculated from the Epigenome) algorithm. In bivariate correlations, DunedinPACE significantly correlated with pain intensity (r = 0.40), and disability (r = 0.39), at p < .05. Pain resilience negatively correlated with pain intensity (rs = -0.22), pain disability (rs = -0.30), and DunedinPACE (r = -0.11). After controlling for chronological age, sex, race, and BMI, mediation analyses revealed a significant indirect association of pain resilience on pain intensity through the pace of biological aging (β = -0.66 (SE); Boot 95% CI [-1.06, -0.25]). Similarly, DunedinPACE partially mediated the relationship between resilience and pain disability (β = -0.82; 95% CI, [-1.20 to -0.44]). We found that higher levels of resilience correlate with a slower pace of biological aging, which in turn correlates with better pain outcomes. The pace of biological aging emerged as an important potential target for future interventions studies for pain management.

DNA methylation affects gene expression. While the Apolipoprotein E (APOE) genotype impacts cardiovascular risk, APOE methylation impact remains unknown, particularly in women with breast cancer (BC). This study explored associations of APOE methylation with hypertension history and cardiovascular fitness (CVF) and whether APOE genotype and methylation moderate exercise effects over 6 months. This study leveraged data from a 6-month exercise randomized clinical trial in postmenopausal women with BC. Using peripheral blood, methylation M-values (Illumina Infinium Methylation EPIC Beadchip) and 13 CpG sites within and 2kb 5' and 3' to APOE were abstracted post data quality checks. Outcome variables: self-reported hypertension and CVF (peak oxygen consumed per kilogram per minute [VO₂max/kg/min] and peak metabolic equivalents [METs] through graded exercise testing). Participants completed 150 min/week of aerobic exercise or usual care for 6 months. Logistic and linear regression examined associations between CpG M-values and hypertension, VO₂max/kg/min and METs. Baseline M-value and APOE genotype were interaction terms for longitudinal analyses. This study included 102 women (Mean = 62 yrs). APOEε4 carriers had increased methylation of cg06750524 (p = 0.04) and cg19514613 (p = 0.03), but lower methylation of cg21879725 (p = 0.04). Increased cg06750524 methylation was associated with higher hypertension odds (p = 0.022, OR = 2.813) and lower VO₂max/kg/min and METs (p = 0.005). Increased cg05501958 methylation (M = 4.539, SD = 0.17) was associated with lower hypertension odds (p = 0.02, OR = 0.035) and higher VO₂max/kg/min and METs (p = 0.022). Neither APOE ε4 nor baseline methylation moderated exercise effects. APOE methylation, differentially by ε4 carriage, may impact cardiovascular outcomes and serve as a biomarker of risk in women with BC.

Purpose: To evaluate the associations between composite dietary antioxidant index (CDAI) and common non-communicable diseases (NCDs) and explore the potential effects of inflammatory indices in these associations. Methods: We included 20,097 adults from the National Health and Nutrition Examination Survey 2003-2018. Multivariable logistic regressions were applied to evaluate the associations between CDAI and common NCDs. Mediation analysis was used to explore the role of inflammatory indices in the associations. Results: Higher CDAI was associated with a downward trend in the incidence of obesity, cardiovascular disease (CVD), chronic respiratory diseases, and chronic kidney disease (CKD) (p for trend < 0.05). The association between CDAI and CVD was influenced by C-reactive protein (CRP), red blood cell width (RDW), and neutrophil to lymphocyte ratio (NLR), with mediated proportions of 3.490%, 5.173%, and 2.351%, respectively. NLR partially contributed to the link between CDAI and CKD, with a mediating ratio of 2.746%. Additionally, we observed additive interactions between CDAI and CRP (RERI (95% CI): 0.282 (0.070, 0.494), AP (95% CI): 0.539 (0.088, 0.991), as well as RDW on CVD (RERI (95% CI): 0.318 (0.124, 0.511), AP (95% CI): 0.717 (0.217, 1.218)). There also appeared to be a weak multiplicative interaction between CDAI and RDW on CVD (p-int = 0.049). Conclusion: Our investigation ascertained that CDAI was related to common NCDs. Moreover, inflammatory indices played an important role in the associations between CDAI and NCDs.

This cross-sectional study compared plasma brain-derived neurotrophic factor (BDNF) levels among chronic primary musculoskeletal pain patients, chronic widespread pain patients, and asymptomatic controls. The study included 126 participants aged 18-65, divided into three groups of 42 each. Pain intensity was assessed using a Numeric Rating Scale (NRS), and plasma BDNF levels were measured via ELISA. Differences between groups were evaluated using ANOVA with 2000 bootstrap resamples and a bias-corrected and accelerated method. Results showed significantly higher plasma BDNF levels in chronic widespread pain patients (mean difference [MD] = 0.44; 95% CI = 0.28, 0.62; p < .001) compared to controls, and higher than in chronic primary musculoskeletal pain patients (MD = 0.83; 95% CI = 0.64, 1.02; p < .001). Chronic primary musculoskeletal pain patients had lower plasma BDNF levels compared to controls (MD = -0.39; 95% CI = -0.54, -0.24; p < .001). No significant correlations were observed between plasma BDNF levels and clinical variables. These findings suggest the potential of BDNF as a biomarker to differentiate chronic primary pain conditions.

Background: Epidural analgesia is a widely employed method in obstetric care for labor pain management. Postpartum urinary retention is a common complication that can arise during the postnatal period. This study aimed to evaluate the current status and influencing factors of postpartum urinary retention in parturients who received epidural anesthesia. Methods: We retrospectively included parturients who underwent vaginal delivery at our institution from June 2022 to October 2024. The characteristics of parturients with and without postpartum urinary retention were analyzed and compared. Logistic regression analyses were conducted to evaluate the influencing factors of postpartum urinary retention. Results: This study enrolled a cohort consisting of 520 parturients who underwent epidural anesthesia, resulting in a total of 520 instances of childbirth. Among this population, 56 parturients were identified as experiencing postpartum urinary retention. The incidence of postpartum urinary retention in parturients with epidural anesthesia was 10.77%. Correlation analysis results showed that the parity (r = 0.582), duration of analgesia (r = 0.554), degree of perineal laceration (r = 0.656) and use of oxytocin (r = 0.580) were correlated with the occurrence of postpartum urinary retention among parturients with epidural anesthesia (all p < .05). Logistic regression analysis indicated that parity (OR = 2.587, 95% CI: 1.890∼3.225), duration of analgesia (OR = 2.778, 95% CI: 2.104∼3.467), degree of perineal laceration (OR = 3.265, 95% CI: 2.620∼3.815) and use of oxytocin (OR = 2.436, 95% CI: 1.909∼3.875) were the independent influencing factors of postpartum urinary retention (all p < .05). Conclusion: It is imperative that clinical healthcare providers implement targeted preventative and management strategies to reduce postpartum urinary retention.

Objective: This study was conducted to examine the effects of massage and foot reflexology on the sleep of premature infants. Materials and Methods: The research was designed as a randomized controlled experimental study. The study population consisted of premature infants born at 30-37 weeks of gestation who were admitted to the Neonatal Intensive Care Unit of a hospital in the Central Anatolia Region. The sample included 108 premature infants divided into three groups: Massage group (n = 36), Foot reflexology group (n = 36), and Control group (n = 36). Data were collected using a neonatal follow-up form and actigraphy. Massage and foot reflexology interventions were administered to the respective groups twice daily (Morning: 07:00-09:00 and Evening: 19:00-21:00) for 15 minutes each session over two consecutive days, making up a total of four sessions. The control group received routine nursing care without any additional intervention. Pre-test (once) and post-test (once) measurements of 24-h sleep durations were assessed using actigraphy for all groups. Results: Sleep duration in the massage group increased compared to pre-intervention (251 minutes) and the control group (272 minutes), while the sleep duration in the foot reflexology group similarly increased compared to pre-intervention (268 minutes) and the control group (266 minutes) (p < .001). Sleep efficiency also showed a significant increase post-intervention, rising to 73% in the massage group and 71.8% in the foot reflexology group compared to the control group (p < .001). Furthermore, the number of awakenings and wakefulness duration significantly decreased in the massage and foot reflexology groups compared to the control group (p < .05). Conclusion: The findings indicate that massage and foot reflexology are effective non-pharmacological methods for improving sleep duration and sleep efficiency while reducing wakefulness duration and the number of awakenings in premature infants.

Maternal mental health conditions significantly contribute to pregnancy-related mortality in the United States. Approximately 20-25% of postnatal women exhibit symptoms of depressive and anxiety disorders. Mental health is influenced by stress, which affects mood, cognition, and behavior. Heart rate variability (HRV), the time interval between consecutive heartbeats, is a physiological marker for assessing stress levels, providing critical insights into the body's autonomic responses. Wearable devices measuring HRV offer a non-invasive method to monitor stress and mental health, enabling early detection of maternal stress dynamics to facilitate timely interventions. In this scoping review, we aimed to capture the current state of science on two areas of focus: (1) utilization of wearable technology for HRV monitoring in pregnant and postpartum women, (2) findings from these perinatal HRV studies, including observed HRV trends throughout pregnancy and postpartum, as well as the association between HRV, perinatal stress, and mental health. The six included perinatal HRV studies employed five fitness tracking wearables, utilizing either periodic or continuous 24-h monitoring. Findings include evidence that HRV declines during pregnancy, with a return to normal levels postpartum. Associations between HRV and stress were inconsistent across studies, with some demonstrating correlations and others reporting no relationship. Postpartum HRV measurements effectively differentiated between women with postpartum depression (PPD) versus those with adjustment disorder (AJD), demonstrating high diagnostic accuracy. In this scoping review, HRV shows promise as a stress biomarker among pregnant/postpartum people, although more work is needed to standardize optimal methods of wearable HRV measurement in this population.
