ABSTRACT

BACKGROUND: Dementia is a growing public health concern with limited effective treatments. Diet may be a modifiable factor that significantly impacts brain health. Mediterranean diet (MeDi) has been suggested to be associated with brain Magnetic Resonance Imaging (MRI) markers related to dementia, but the existing evidence is inconsistent.

OBJECTIVES: This systematic review and meta-analysis aimed to quantify the association between MeDi and dementia-related MRI markers.

METHODS: A systematic search was conducted on PubMed, Embase, and Web of Science up to September 2024. Two reviewers worked in parallel to select studies and extract data. We considered epidemiologic studies that reported beta coefficients (β) with 95% confidence intervals (CIs) for MRI markers related to MeDi. Separate meta-analyses were performed for cross-sectional and longitudinal studies.

RESULTS: A total of 20 relevant studies involving 44,893 individuals were included in the analysis. Thirteen cross-sectional studies included a total of 42,955 participants. A meta-analysis of cross-sectional studies revealed significant associations between MeDi and white matter hyperintensity (WMH) (β = – 0.03, 95% CI = – 0.05- – 0.01, P = 0.02). However, there were no significant associations found between MeDi and total brain volume (TBV) (β = – 0.03, 95% CI = – 0.20-0.13, P = 0.71), gray matter volume (GMV) (β = 0.26, 95% CI = – 0.19-0.71, P = 0.26), white matter volume (WMV) (β = – 0.09, 95% CI = – 0.40-0.22, P = 0.58), or hippocampal volume (HCV) (β = – 1.02, 95% CI = – 7.74-9.79, P = 0.82). In the longitudinal analysis, seven prospective studies with an average follow-up period ranging from 1.5 to 9 years and involving 1,938 participants. The combined effect size of MeDi showed no significant association with TBV or GMV.

CONCLUSION: Adherence to MeDi may be associated with reduced WMH in older adults. This suggests that MeDi may affect brain health and highlights the need for further research into its role as a modifiable lifestyle factor that might potentially modify the risk of dementia.

ABSTRACT

BACKGROUND: Lebanon has experienced a series of devastating crises that continue to have significant adverse effects on the mental health of parents and their children, especially those who are unemployed, burdened with debt or financial difficulties, and have pre-existing mental health conditions. Accordingly, this study aimed to assess the effect of financial insecurities on parents in Lebanon amid the multiple crises, and the impact of parents’ mental health on their children’s emotional and behavioral wellbeing.

METHODS: A cross-sectional study including 589 parents in Lebanon was performed using convenience sampling of parents of any gender with children aged 4 to 18 from the five Lebanese governorates. The study collected the sociodemographic data of the participants and incorporated supplementary measures such as the Parental Stress Scale (PSS), Pediatric Symptom Checklist (PSC), and the InCharge Financial Distress/Financial Well-Being (IFDFW) scale. Statistical tests included bivariate analysis, ANOVA test, linear regression, and mediation analyses.

RESULTS: A total of 589 parents, primarily mothers, participated in this study. Most children were males in elementary school. Bivariate analyses revealed that parents with non-Lebanese nationality, primary education, employment, or children in technical schools reported significantly higher PSS and PSC scores. Negative correlations were observed between the IFDFW scale and both PSS (r=-0.200, p < 0.001) and PSC scores (r=-0.086, p = 0.038), indicating lower stress and symptoms with improved financial well-being. Multivariable analysis showed that higher PSC scores, age, complementary education, and Lebanese nationality were associated with increased parental stress, while unemployment, lower age, and higher IFDFW were associated with reduced stress. Similarly, higher PSC scores were linked to increased parental stress, age, non-Lebanese nationality, and IFDFW, whereas university education, higher GPA, and residence outside Beirut/Mount Lebanon were associated with reduced PSC scores. Mediation analysis indicated that parental stress fully mediated the relationship between IFDFW and PSC scores, underscoring the impact of financial well-being on a child’s psychological symptoms via parental stress.

CONCLUSIONS: The study revealed significant financial distress and low financial well-being among participants amid Lebanon’s economic crisis, with a notable mediated association between financial well-being, parental stress, and child mental health symptoms. Parental stress was heightened among those with lower education levels, non-Lebanese nationality, and employment in low-wage jobs, with children from these families exhibiting elevated mental health symptoms. Additionally, regional factors and socioeconomic status played a role, as children in urbanized areas and technical schools reported higher distress. Targeted interventions are urgently recommended to alleviate financial and emotional burdens on families and ensure improved mental well-being for both parents and children.

ABSTRACT

BACKGROUND: Multimorbidity is associated with significant out-of-pocket expenditures (OOPE) and catastrophic health expenditure (CHE), especially in low- and middle-income countries like India. Despite this, there is limited research on the financial burden of multimorbidity in outpatient and inpatient care, and cross-state comparisons of CHE are underexplored.

METHODS: We conducted a cross-sectional analysis using nationally representative data from the National Sample Survey 75th Round ‘Social Consumption in India: Health (2017-18)’, focusing on patients aged 30 and above in outpatient and inpatient care in India. We assessed multimorbidity prevalence, OOPE, CHE incidence, and CHE intensity. Statistical models, including linear, log-linear, and logistic regressions, were used to examine the financial risk, with a focus on non-communicable diseases (NCDs), healthcare facility choice, and socioeconomic status and Epidemiological Transition Levels (ETLs).

RESULTS: Multimorbidity prevalence in outpatient care (6.1%) was six times higher than in inpatient care (1.1%). It was most prevalent among older adults, higher MPCE quintiles, urban patients, and those with NCDs. Multimorbidity was associated with higher OOPE, particularly in the rich quintile, patients seeking care from private providers, low ETL states, and rural areas. CHE incidence was highest in low ETL states, private healthcare users, poorest quintile, males, and patients aged 70 + years. CHE intensity, measured by mean positive overshoot, was greatest among the poorest quintile, low ETL states, rural, and male patients. Log-linear and logistic regressions indicated that multimorbidity patients with NCDs, those seeking private care, and those in low ETL states had higher OOPE and CHE risk. The poorest rural multimorbidity patients had the greatest likelihood of experiencing CHE. Furthermore, CHE intensity was significantly elevated among multimorbidity patients with NCDs (95% CI: 19.29-45.79), patients seeking care in private, poorest, and from low ETL states (95% CI: 7.36-35.79).

CONCLUSIONS: The high financial burden of OOPE and CHE among multimorbidity patients, particularly those with NCDs, highlight the urgent need for comprehensive health policies that address financial risk at the primary care level. To alleviate the financial burden among multimorbidity patients, especially in low-resource settings, it is crucial to expand public healthcare coverage, incorporate outpatient care into financial protection schemes, advocate for integrated care models and preventive strategies, establish standardized treatment protocols for reducing unnecessary medications linked to polypharmacy, and leverage the support of digital health technologies.

ABSTRACT

BACKGROUND: People in justice settings experience higher rates of psychiatric morbidity, including alcohol and drug use disorders, compared with the general population. However, our understanding of opioid-related harms in justice settings is limited. This study used ambulance data to examine opioid-related harms and experiences of care in New South Wales (NSW), Australia, during periods of incarceration or detention.

METHODS: This mixed-methods study used data from the National Ambulance Surveillance System (NASS) for patients aged 18 and older with an opioid-related ambulance attendance between December 2020 and April 2023. People in justice settings were identified using ambulance billing codes and manual review of paramedic case notes. Descriptive statistics described the patterns and modalities of opioid-related harms in justice settings, and a qualitative thematic analysis of paramedic case notes was used to contextualise findings. Results Over the study period, 328 opioid-related ambulance attendances for people in justice settings were identified (51% heroin; 41% opioid agonist therapy (OAT) medication). Symptoms of opioid withdrawal were noted in 35% of attendances, most commonly for heroin (51%) and withdrawal from OAT medications (48%). Three interconnected themes were identified using qualitative analysis: trust and mistrust in justice settings, systemic barriers to providing OAT, and other harm reduction strategies, and experiences of withdrawal in justice settings.

CONCLUSION: Our study demonstrated the utility of ambulance data in identifying opioid-related harms for people in justice settings in NSW. Qualitative findings highlight current barriers to effective opioid care in justice settings and identify opportunities for intervention, including targeted harm reduction programs, as well as policies that promote continuity of care particularly during transitions in and out of justice settings.

ABSTRACT

INTRODUCTION: The attachment a mother feels for her fetus intensifies her duty to care for it, leading to a heightened desire to engage in behaviors that promote health. This research explored the association between maternal-fetal attachment (MFA) and adherence to health-related behaviors among pregnant women.

METHODS: This cross-sectional study focused on 220 pregnant women in Jahrom City, and was conducted using a multi-stage random sampling strategy. The data were collected using the Maternal-Fetal Attachment Scale paired with a questionnaire that addressed health behaviors relevant to pregnancy. The data were analyzed using SPSS18 software, employing linear regression and the Pearson correlation test. A p-value of less than 0.05 was deemed significant.

RESULTS: The mean age of participants was 28.06 ± 5.12 years. The adherence to health behaviors in pregnant women yielded a mean score of 174.51 ± 20.20. Pearson’s correlation test revealed a significant statistical association between MFA and adherence to health behaviors (r = 0.54, p < 0.001). The linear regression analysis showed that the dimensions of interaction with the fetus (β = 0.19) and the act of surrendering to the fetus (β = 0.27) could explain 35% of the variance in adherence to health behaviors (F = 14.12, R2 = 0.35, p < 0.001).

CONCLUSION: This study highlights a significant association between MFA and adherence to health behaviors throughout pregnancy. Supportive measures may strengthen MFA, promoting self-care practices and behaviors, ultimately resulting in improved health for both the mother and her fetus.

ABSTRACT

Genome-wide association studies (GWAS) have identified genetic variants robustly associated with asthma. A potential near-term clinical application is to calculate polygenic risk score (PRS) to improve disease risk prediction. The value of PRS, as part of numerous multi-source variables used to define asthma, remains unclear. This study aims to evaluate PRS and define most informative thresholds in relation to conventional clinical and physiological criteria of asthma using a multivariate statistical method. Clinical and genome-wide genotyping data were obtained from the Quebec City Case-Control Asthma Cohort (QCCCAC), which is an independent cohort from previous GWAS. PRS was derived using LDpred2 and integrated with other asthma phenotypes by means of Principal Component Analysis with Optimal Scaling (PCAOS). PRS was considered using ‘ordinal level of scaling’ to account for non-linear information. In two dimensional PCAOS space, the first component delineated individuals with and without asthma, whereas the severity of asthma was discerned on the second component. The positioning of high vs. low PRS in this space matched the presence and absence of airway hyperresponsiveness, showing that PRS delineated cases and controls at the same extent as a positive bronchial challenge test. The top 10% and the bottom 5% of the PRS were the most informative thresholds to define individuals at high and low genetic risk of asthma in this cohort. PRS used in a multivariate method offers a decision-making space similar to hyperresponsiveness in this cohort and highlights the most informative and asymmetrical thresholds to define high and low genetic risk of asthma.

ABSTRACT

INTRODUCTION: Organ transplant recipients face a substantial risk of developing posttransplant lymphoproliferative disorders (PTLD). In over 90% of cases with B-cell PTLD following solid organ transplantation, the Epstein-Barr virus (EBV) genome is promptly identified, usually within the initial year. A continuing discussion revolves around the efficacy of antiviral prophylaxis in mitigating the incidence of PTLD in solid organ transplant (SOT) patients. This study aimed to conduct a systematic review and meta-analysis to investigate this issue.

METHOD: A comprehensive search was conducted up to December 31, 2023, in databases including PubMed, Embase, and the Cochrane Library for retrospective and prospective studies comparing antiviral prophylaxis effects on EVB viremia and PTLD incidence in SOT recipients. Fixed or random effect models were applied based on the heterogeneity assessed via the I² statistic, using Stata 16.0 software for data analysis.

RESULTS: In total, 22 eligible studies involving 13,498 patients were analyzed. Antiviral prophylaxis was associated with a significant reduction in EBV viremia incidence in SOT recipients, as demonstrated in 10 studies (relative risk (RR) 0.69, 95% CI 0.54 to 0.88). The rate of PTLD was significantly lower among those who received antiviral prophylaxis compared to those who did not, as reported in 18 studies (RR 0.77, 95% CI 0.63 to 0.94). No significant difference was observed in the subgroup of high-risk recipients based on EBV serology (RR 1.13, 95% CI 0.72 to 1.78). Additionally, a notable reduction in PTLD incidence was seen in the pediatric subgroup (RR 0.58, 95% CI 0.43 to 0.79) using antiviral prophylaxis, while no significant differences were observed in the subgroup of adults (RR 0.88, 95% CI 0.64 to 1.21). Administration of antiviral prophylaxis can significantly reduce the incidence of PTLD among kidney (RR 0.63, 95% CI 0.46 to 0.87) and heart transplant patients (RR 0.61, 95% CI 0.39 to 0.96). PTLD incidence was significantly reduced among recipients of T-cell depletion or steroid-based immunosuppression using antiviral prophylaxis (RR 0.54, 95% CI 0.39-0.74 and RR 0.55, 95% CI 0.41-0.73, respectively).

CONCLUSION: This meta-analysis revealed that administering antiviral prophylaxis to patients after solid organ transplantation reduces PTLD and EBV viremia occurrences, especially among pediatric recipients, individuals undergoing kidney or heart transplantation, and those receiving high-intensity immunosuppression regimens. Post-transplant lymphoproliferative disorders (PTLD) and other EBV syndromes are among the most serious complications following solid organ transplantation (SOT), primarily due to the necessity for prolonged immunosuppressive therapy. Among the strategies for preventing EBV-related complications, the use of antiviral prophylaxis is a subject of ongoing debate. This systematic review and meta-analysis found that antiviral prophylaxis significantly reduced EBV viremia incidence (risk ratio (RR) 0.69, 95% confidence interval (CI) 0.54 to 0.88) compared to those without prophylaxis. In the sub-analysis related to high-risk EBV serologically mismatched SOT recipients (EBV D+/R-), the result did not show a significant difference in terms of PTLD incidence (RR 1.13, 95% CI 0.72 to 1.78). Antiviral prophylaxis significantly impacted the occurrence of PTLD events among pediatric SOT patients (RR 0.58, 95% CI 0.43 to 0.79), but not among adult patients (RR 0.88, 95% CI 0.64 to 1.21). Antiviral prophylaxis significantly impacted the occurrence of PTLD events among kidney/simultaneous pancreas and kidney (RR 0.63, 95% CI 0.46 to 0.87) and heart (RR 0.61, 95% CI 0.39 to 0.96) transplant patients but not liver (RR 0.5, 95% CI 0.23 to 1.08) transplant recipients.

ABSTRACT

BACKGROUND: This article aims to use high-throughput sequencing to identify miRNAs associated with ferroptosis in myocardial ischemia-reperfusion injury, select a target miRNA, and investigate its role in H9C2 cells hypoxia-reoxygenation injury.

METHODS: SD rats and H9C2 cells were used as subjects. ELISA kits quantified MDA, SOD, GSH, LDH, and ferritin levels. TTC staining evaluated infarction size. HE staining observed histopathological changes. DCFH-DA fluorescent probe detected ROS. CCK-8 kit measured cell viability. HiSeq 2000 sequencing performed differential expression analysis of miRNAs. qRT-PCR and Western blots assessed the expression levels of GPX-4, ACSL-4, HO-1, TFR-1 and TFR-2. SPSS 21.0 software conducted statistical analysis.

RESULTS: Myocardial ischemia-reperfusion injury resulted in decreased levels of SOD and GSH, increased levels of LDH and MDA, up-regulation of ferritin, ACSL-4, HO-1, and TFR-2, down-regulation of GPX-4, increased tissue damage, and accumulation of ROS. However, DFO treatment reversed these changes. Subsequently, the target gene miRNA-541-5p was obtained by miRNA sequencing screening, and further validation revealed that miRNA-541-5p expression was increased in the myocardial tissues of rats in the I/R injury model group compared with those of rats in the NC group, P < 0.05. Subsequently, by constructing H9C2 cell lines with miRNA-541-5p overexpression and miRNA-541-5p expression inhibition, miRNA-541-5p expression was inversely correlated with the survival of H9C2 cells after hypoxia-reoxygenation injury. miRNA-541-5p up-regulation led to a decrease in SOD and GSH, an increase in ferritin and MDA, and an accumulation of ROS. wb and qRT-PCT demonstrated that high miRNA-541-5p expression up-regulated the expression of protein/mRNA expression of ACSL-4, HO-1, ferritin, and TFR-1, but down-regulated protein/mRNA expression of GPX-4. In addition, ADAM 7, FNIP 2, HOXD 10, HCCS and STK 3 were preliminarily identified as potential candidate target genes for miRNA-541-5p by bioinformatics analysis. Among them, ADAM7 emerges as the most suitable potential target gene based on the selection criteria.

CONCLUSION: In summary, miRNA-541-5p may be a biomarker of myocardial I/R damage diseases and can regulate oxidative stress and iron death by inhibiting the expression of miRNA-541-5p, thereby reducing mechanisms of I/R injury.

ABSTRACT

BACKGROUND: The continued healthcare crisis in the United States (US) is worrisome, especially as workforce shortages, particularly for nurses, are highlighted, often in some of the highest need areas. As the need for healthcare services grows, especially for services that nurses can deliver, the inability to meet those needs exacerbates existing disparities in access to care and can jeopardize the quality and timeliness of healthcare delivery in underserved communities. Prior investigations have used varying definitions to describe underserved, under-resourced, rural, or health professional shortage areas to examine the relationship between these areas and workforce shortages. Therefore, this study examines the relationship between changes in the nursing labor force changes and metropolitan medically underserved areas (MUA), defined by Health Resources and Services Administration (HRSA).

METHODS: Secondary data were utilized to conduct descriptive and regression analyses of the nursing workforce population in metropolitan statistical areas from 2012 to 2022. The key outcome variable for the analyses was nurse workforce change per 10,000 population. Occupational Employment and Wage dataset from the Bureau of Labor Statistics was used to determine the number of nurses employed, at the level of the metropolitan statistical area from 2012 to 2022. The Index of Medical Underservice was extracted for each MUA from HRSA and geographically weighted to the metropolitan area.

RESULTS: The results of descriptive trends for nursing professions show that all nursing occupations reviewed have experienced positive change over both five- and ten-year periods. However, the results of nurse change models show that neither the change in Registered Nurses nor Nurse Practitioners is correlated with medically underserved areas.

CONCLUSIONS: These results emphasize the need for adaptive strategies in the nursing workforce to respond to the evolution of healthcare requirements over time. The findings from this study suggest the need for careful planning in workforce policy and education to grow the nurse workforce needs to meet evolving healthcare needs effectively.

ABSTRACT

Electronic health records (EHRs) provide a rich source of observational patient data that can be explored to infer underlying causal relationships. These causal relationships can be applied to augment medical decision-making or suggest hypotheses for healthcare research. In this study, we explored a large-scale EHR dataset on patients with asthma or related conditions (N = 14,937). The dataset included integrated data on features representing demographic factors, clinical measures, and environmental exposures. The data were accessed via a service named the Integrated Clinical and Environmental Service (ICEES). We estimated underlying causal relationships from the data to identify significant predictors of asthma attacks. We also performed simulated interventions on the inferred causal network to detect the causal effects, in terms of shifts in probability distribution for asthma attacks.
