An integrated investigation of mitochondrial genes in COPD reveals the causal effect of NDUFS2 by regulating pulmonary macrophages

Biol Direct. 2025 Jan 9;20(1):4. doi: 10.1186/s13062-025-00593-3.

ABSTRACT

BACKGROUND: Despite the increasing body of evidence that mitochondrial activities implicate in chronic obstructive pulmonary disease (COPD), we are still far from a causal-logical and mechanistic understanding of the mitochondrial malfunctions in COPD pathogenesis.

RESULTS: Differential expression genes (DEGs) from six publicly available bulk human lung tissue transcriptomic datasets of COPD patients were intersected with the known mitochondria-related genes from MitoCarta3.0 to obtain mitochondria-related DEGs associated with COPD (MitoDEGs). The 32 hub MitoDEGs identified from protein-protein interaction (PPI) networks demonstrated superior overall diagnostic efficacy to non-hub MitoDEGs. Random forest (RF) analysis, least absolute shrinkage and selection operator (LASSO) regression, and Mendelian Randomization (MR) analysis of hub MitoDEGs further nominated NDUFS2, CAT, and MRPL2 as causal MitoDEGs for COPD, whose predominate expressions in pulmonary macrophages were revealed by an independent single-cell transcriptomic dataset of COPD human lungs. Finally, NDUFS2 was evaluated as the top-ranked contributor to COPD in the nomogram model and its downregulation in pulmonary macrophages could result in pro-inflammatory secretion, enhanced intercellular communications, whereas depressed phagocytosis of macrophages as revealed by gene set variation analysis (GSVA) and cell-cell interaction (CCI) analysis of single-cell transcriptomic dataset of COPD human lungs, which was later confirmed in COPD mouse model and macrophage cell lines.

CONCLUSIONS: Our study established the causal linkage between mitochondrial malfunctions and COPD, providing a potential therapeutic avenue to alleviate pulmonary inflammation accounting for COPD by targeting mitochondria-related genes. NDUFS2, a canonical component of mitochondrial electron respiratory chain, was highlighted instrumental for the susceptibility of risk-exposed individuals to COPD.

Oxidative balance scores and gallstone disease: mediating effects of oxidative stress

Nutr J. 2025 Jan 10;24(1):4. doi: 10.1186/s12937-025-01073-0.

ABSTRACT

BACKGROUND: Gallstone disease (GSD) is a prevalent gastrointestinal disorder, few studies have examined the combined effects of dietary and lifestyle factors on GSD. This study aims to investigate the relationship between oxidative balance score (OBS) and GSD, and explores the potential mediating role of oxidative stress.

METHODS: Cross-sectional data from 6,196 participants in the NHANES 2017-2020 were analyzed. OBS, encompassing 16 dietary and 4 lifestyle factors, was assessed alongside GSD prevalence. Weighted multivariate logistic regression, restricted cubic spline (RCS) analysis were used to explore the relationship between OBS and GSD and mediation analysis was used to test the indirect effect of oxidative stress indicators. Subgroup analysis and sensitivity analysis were used to determine the stability of results.

RESULTS: A higher OBS was significantly associated with a reduced risk of GSD (OR: 0.701, 95% CI: 0.492-0.999, P < 0.05). RCS analysis revealed a linear association between OBS and GSD risk. Mediation analysis indicated significant mediating effects of albumin and uric acid, with a combined mediation proportion of 19.540% (P < 0.05). Subgroup analysis revealed differences and interrelationships based on education level, providing additional insights into the relationship between OBS and GSD and sensitivity analysis confirmed the stability of these associations.

CONCLUSIONS: A higher OBS is associated with a reduced risk of GSD, especially among higher education levels groups, and albumin, uric acid may act as mediators of this association. These findings underscore the potential role of oxidative stress in GSD and the significance of maintaining a healthy diet and lifestyle to decrease GSD risk.

Effects of the Oral Health Promotion Program on oral health and oral microbiota changes in diabetic elderly individuals: a quasi-experimental study

BMC Oral Health. 2025 Jan 9;25(1):51. doi: 10.1186/s12903-024-05388-y.

ABSTRACT

BACKGROUND: Diabetes with its highly prevalence has become a major contributor to the burden of health care costs worldwide. Recent unequivocal evidence has revealed a bidirectional link between oral health and diabetes. In this study, the effects of the Oral Health Promotion Program (OHPP) on oral hygiene, oral health-related quality of life and glycated haemoglobin (HbA1c) levels in diabetic elderly were examined. Moreover, microbial changes in the saliva microbiota community were also emphatically investigated.

METHODS: A quasi-experiment was conducted in regionally representative communities to assess oral health and oral microbiota of the elderly diabetic participants. The participants in the intervention group (n = 26) received OHPP including three phases of cognition, intensification and consolidation during the program, when those in the control group (n = 26) received routine oral care. Clinical parameters were recorded at two different time points as before the study (T0), and 3 months after intervention onset (T1). Oral health was measured via the oral health impact profile (OHIP-14) questionnaire, dental plaque index, HbA1c and mastery of oral health knowledge, and sequencing of the 16S rRNA gene from saliva samples was used to analyze the oral microbiota.

RESULTS: The average age of the final sample was 71.77 years (SD = 6.06), 53.8% (28/52) of whom were male. A reduction in the plaque index and improvements in oral health-related quality of life and mastery of oral health knowledge were observed in the intervention group. Meanwhile, the α-diversity of the microbiota increased in both groups, but more significant in the intervention group. PCoA analyses showed significant differences in microbial community structure in both groups, and LEfSe analyses revealed a decrease of g_Streptococcus and g_Rothia after the implementation of OHPP and a decrease of g_Streptococcusa, g_Porphyromonas, g_Gemella after the routine oral care. There was no statistically significant difference in the HbA1c level between two groups.

CONCLUSIONS: OHPP superiorly contributes to the improvement of oral health and oral microbiota in elderly diabetic patients. The overarching goal is to introduce attention to the importance of good oral health as a crucial point in preventing and managing diabetes mellitus and thereby make it a meaningful contribution to public health and geriatric care.

TRIAL REGISTRATION: This study was retrospectively registered in Chinese Clinical Trial on October 9, 2022 (ID ChiCTR2200064453).

A protocol to study the effect of targeted parental education intervention to identify early childhood development disorder – multisite interventional study

Arch Public Health. 2025 Jan 10;83(1):7. doi: 10.1186/s13690-024-01495-y.

ABSTRACT

BACKGROUND: In India, approximately 3.5 million children are affected by Developmental Delay (DD), often stemming from preterm births. These delays contribute to neurological and motor development delays, placing a significant financial burden on families. Maternal unemployment rates are also elevated in such cases. Delayed Developmental Milestones identification, often due to a lack of parental awareness, further compounds these challenges. This study introduces a multiphasic approach aimed at educating antenatal women on monitoring neurological maturation, with the overarching objective of assessing the effectiveness of a targeted multi-method parental education intervention in improving parents’ knowledge and early detection of developmental disorders in early childhood.

METHODS: Antenatal women will be assigned to intervention or control groups. The intervention group will undergo specialized training in a multiphasic study, while the control group will receive routine care. A meticulously developed intervention module for early detection of neurodevelopmental disorders will empower mothers to monitor their newborns for potential deficits. Outcomes will be assessed through questionnaires, analyzing knowledge improvement and early identification of DD using statistical methods such as chi-square tests. The study involves three phases: preparatory, implementation, and evaluation, aiming to empower mothers to detect developmental concerns early and improve maternal awareness of child development. The study was approved by the SRM Institutional Ethical Committee with the reference number 8688/IEC/2023.

DISCUSSION: This study will identify DD and improve parental awareness by providing tools for early detection thereby empowers parents to identify developmental concerns early. The study supports policy goals to reduce the burden of DD, enhance early intervention, and improve long-term outcomes for children. It is anticipated that this intervention will complement existing health policies, contributing to better child health and developmental outcomes in India.

TRIAL REGISTRATION: Trail is registered under Clinical Trails Registry – India (CTRI/2024/04/065008) registered on 01 April 2024.

The mediating effects of perceived usefulness and perceived ease of use on nurses’ intentions to adopt advanced technology

BMC Nurs. 2025 Jan 9;24(1):33. doi: 10.1186/s12912-024-02648-8.

ABSTRACT

This study explored the role of technology systems in influencing nurses’ intentions to adopt medical applications that enhance their performance and how technology contributes to improvements in hospital systems. The study examines the intention to use technology through the mediating effects of perceived usefulness and perceived ease of use, with technology sophistication. A random sampling method was employed to gather 687 responses from nurses. The statistical analysis was conducted using AMOS version 25.0 and SPSS. The findings indicate a significant association between technology sophistication (TS), perceived usefulness (PU), perceived ease of use (PEU), and intention to use (IU). Additionally, PU and PEU positively mediate the relationship between TS and IU. This research will benefit policymakers aiming to enhance nurses’ performance by adopting modern technology. Authorities should consider introducing advanced technology systems to meet the goals of hospital administration and support nurses effectively.

Impact of hopelessness on migration intentions of nursing students: a path analysis

BMC Nurs. 2025 Jan 9;24(1):29. doi: 10.1186/s12912-024-02667-5.

ABSTRACT

BACKGROUND: Brain drain refers to the migration of qualified professionals to developed countries in search of better living and working conditions, and has become a global concern, particularly in the healthcare sector. Migration of highly skilled nurses results in increased workload for the remaining nursing staff, limited access to quality healthcare services, and contributes to disparities in healthcare. Therefore, nursing students represent a critical demographic group for understanding the drivers of brain drain in the healthcare sector.

PURPOSE: This study aimed to assess the levels of hopelessness experienced by nursing students in Turkey throughout their education and to examine the impact of hopelessness on their decisions to move abroad.

MATERIALS AND METHODS: The study was conducted on 795 students enrolled in the nursing departments of two public universities in Gaziantep. Data were collected using a Demographic Data Form, the Beck Hopelessness Scale, and the Attitudes Towards Brain Drain Scale. The data were analyzed using the SPSS 24.0 statistical software.

RESULTS: 57% of the nursing students considered moving abroad, with 20.2% preferring Germany. The primary reasons for their desire to migrate included poor living conditions (11.1%), economic problems (12.9%), unfavorable working conditions (8.3%), and educational challenges (5.4%). The findings highlight the significant role of future hopelessness in influencing the migration intentions of nursing students.

CONCLUSION: More than half of Turkish nursing students consider moving abroad to seek better working conditions, higher living standards, financial gains and educational opportunities, with Germany being their top destination country. Despite low levels of hopelessness observed among the students, the tendency for migration persisted. A retention policy needs to be developed with strategic actions to prevent nurses from migrating to other countries.

CLINICAL TRIAL NUMBER: not applicable.

Late-life physical activity, midlife-to-late-life activity patterns, APOE ε4 genotype, and cognitive impairment among Chinese older adults: a population-based observational study

Int J Behav Nutr Phys Act. 2025 Jan 9;22(1):5. doi: 10.1186/s12966-024-01691-7.

ABSTRACT

BACKGROUND: Although physical activity (PA) has been linked to cognitive health, the nuanced relationships between different dimensions of PA and cognitive impairment remain inconclusive. This study investigated associations between late-life PA levels, midlife-to-late-life activity patterns, and cognitive impairment in Chinese older adults, considering potential moderation by apolipoprotein E (APOE) ε4 genotype.

METHODS: We analyzed baseline data from 6,899 participants (median age 68 years, 55.78% female) in the West China Health and Aging Cohort study, with 6,575 participants having APOE genotyping data. Late-life PA and midlife-to-late-life activity patterns were assessed using the Global Physical Activity Questionnaire and a standardized question, respectively. Cognitive function was evaluated using the Chinese version of Mini-Mental State Examination. Logistic regression models were used to examine associations.

RESULTS: Compared to low PA level, moderate (odds ratio [OR] = 0.74, 95% confidence interval [CI] = 0.55 ~ 0.99) and high PA levels (OR = 0.60, 95%CI = 0.48 ~ 0.75) were associated with lower risk of cognitive impairment. Engaging in work-, transport-, recreation-related, and moderate-intensity PA were each significantly associated with lower cognitive impairment risk. Maintaining activity levels from midlife to late life was associated with lower cognitive impairment risk compared to decreasing levels (OR = 0.75, 95%CI = 0.60 ~ 0.94). These associations were more pronounced in APOE ε4 non-carriers, with an interaction observed between APOE ε4 genotype and recreation-related PA (P-value = 0.04).

CONCLUSIONS: Our findings underscore the multifaceted benefits of PA in mitigating cognitive impairment risk among older Chinese adults. Public health strategies should focus on promoting overall late-life PA levels, especially moderate-intensity PA, and maintaining activity levels comparable to midlife, with potential for personalized interventions based on genetic risk profiles.

Predicting loss of independence among geriatric patients following gastrointestinal surgery

Patient Saf Surg. 2025 Jan 9;19(1):1. doi: 10.1186/s13037-024-00424-w.

ABSTRACT

BACKGROUND: While existing risk calculators focus on mortality and complications, elderly patients are concerned with how operations will affect their quality of life, especially their independence. We sought to develop a novel clinically relevant and easy-to-use score to predict elderly patients’ loss of independence after gastrointestinal surgery.

METHODS: This retrospective cohort study included patients age ≥ 65 years enrolled in the American College of Surgeons National Surgical Quality Improvement Program database and Geriatric Pilot Project who underwent pancreatic, colorectal, or hepatic surgery (January 1, 2014- December 31, 2018). Primary outcome was loss of independence – discharge to facility other than home and decline in functional status. Patients from 2014 to 2017 comprised the training data set. A logistic regression (LR) model was generated using variables with p < 0.2 from the univariable analysis. The six factors most predictive of the outcome composed the short LR model and scoring system. The scoring system was validated with data from 2018.

RESULTS: Of 6,510 operations, 841 patients (13%) lost independence. Training and validation datasets had 5,232 (80%) and 1,278 (20%) patients, respectively. The six most impactful factors in predicting loss of independence were age, preoperative mobility aid use, American Society of Anesthesiologists classification, preoperative albumin, non-elective surgery, and race (all OR > 1.83; p < 0.001). The odds ratio of each of these factors were used to create a sixteen-point scoring system. The scoring system demonstrated satisfactory discrimination and calibration across the training and validation datasets, with Receiver Operating Characteristic Area Under the Curve 0.78 in both and Hosmer-Lemeshow statistic of 0.16 and 0.34, respectively.

CONCLUSIONS: This novel scoring system predicts loss of independence for geriatric patients after gastrointestinal operations. Using readily available variables, this tool can be applied in the urgent setting and can contribute to elderly patients and their family discussions related to loss of independence prior to high-risk gastrointestinal operations. The applicability of this scoring tool to additional surgical sub-specialties and external validation should be explored in future studies.

Assessing neonatal nurses: transitioning preterm infants to oral feeding – a multicenter cross-sectional study

BMC Nurs. 2025 Jan 9;24(1):32. doi: 10.1186/s12912-024-02647-9.

ABSTRACT

BACKGROUND: In Egypt, approximately 10% of preterm deliveries occur between 32 and fewer than 37 weeks, leading to high neonatal intensive care unit (NICU) admissions. Preterm infants often face oral feeding difficulties due to immature development, which can lead to extended hospital stays and increased health risks.

AIM: To assess neonatal nurses’ performance in terms of the transition to oral feeding in preterm infants, focusing on knowledge, practices, and attitudes.

METHODS: A descriptive, quantitative, multicenter, cross-sectional study was conducted across 16 hospitals in five governorates in Egypt from November 2023 to March 2024 involving 553 neonatal nurses. The data were collected through a self-administered questionnaire assessing knowledge and attitudes and through an observed checklist for nurses’ practices. The study used statistical methods, including binary logistic regression, to analyze the data.

RESULTS: The findings revealed significant knowledge gaps among nurses, particularly in terms of oro-motor function, suck-swallow-breathe patterns, and nonnutritive sucking. A total of 64.6% of the nurses had unsatisfactory knowledge, 58.6% had unsatisfactory practices, and 45% had a negative attitude toward the oral feeding transition. Key predictors of satisfactory practices included higher education levels, full-time employment, and positive attitudes.

CONCLUSION: This study highlights critical gaps in neonatal nurses’ knowledge and practices regarding the transition to oral feeding in preterm infants. Addressing these gaps through targeted educational interventions and ongoing support is essential for improving care quality and outcomes for infants. The findings revealed that a substantial proportion of nurses lacked adequate knowledge of critical areas, such as oro-motor function, the suck-swallow-breathe pattern, and nonnutritive sucking. These knowledge deficits could hinder the ability of nurses to provide optimal care during this crucial transition.

Indirect determination of hemoglobin A2 reference intervals in Pakistani infants using data mining

BMC Med Inform Decis Mak. 2025 Jan 9;25(1):15. doi: 10.1186/s12911-025-02857-4.

ABSTRACT

BACKGROUND: Reference intervals (RIs) are crucial for distinguishing healthy from sick individuals and vary across age groups. Hemoglobinopathies are common in Pakistan, making the quantification of hemoglobin variants essential for screening. Direct RIs are established by measuring values from a healthy reference population, whereas indirect RIs, use statistical analysis of routine lab data to estimate values, making it feasible in settings where direct data is unavailable. Since Pakistan lacks locally established Hemoglobin A2 RIs for infants, this study aims to fill that gap using an indirect data mining method to improve diagnostic accuracy for hemoglobinopathies.

METHODS: It was a retrospective observational study. Hemoglobin A2 measurements from all patients aged birth to 1 year between January 2015 and December 2022 were retrieved from the laboratory management system at Aga Khan University Hospital. The study population represented the entire geographical distribution of the country. Hemoglobin A2 was measured using the Bio-Rad Variant™ II analyzer. RIs were computed using an indirect KOSMIC algorithm, which assumes non-pathologic samples follow a Gaussian distribution after Box-Cox transformation.

RESULTS: A total of 88,690 specimens were analyzed for HbA2. After excluding patients with multiple specimens, RIs were calculated for 22,713 infants, stratified into five age sub-groups. The 2.5th and 97.5th percentile results showed good agreement with RIs from Mayo Clinic Laboratories.

CONCLUSIONS: This study supports data mining as an alternative method for establishing HbA2 RIs, especially in resource-limited settings. The results are specific to the studied population, instrument, and reagent, and they elucidate the fluctuations in HbA2 synthesis with age. These intervals will enhance clinical decision-making based on HbA2 results.
