Published: April 2024

Abstract
Background
Migration is increasing globally, and societies are becoming more diverse and multi-ethnic. Medical school curricula should prepare students to provide high-quality care to all individuals in the communities they serve. Previous research from North America and Asia has assessed the effectiveness of medical cultural competency training, and student preparedness for delivery of cross-cultural care. However, student preparedness has not been explored in the European context. The aim of this study was to investigate how prepared final-year medical students in the Republic of Ireland (ROI) feel to provide care to patients from other countries, cultures, and ethnicities. In addition, this study aims to explore students’ experiences and perceptions of cross-cultural care.

Methods
Final-year medical students attending all six medical schools within the ROI were invited to participate in this study. A modified version of the Harvard Cross-Cultural Care Survey (CCCS) was used to assess their preparedness, skill, training/education, and attitudes. The data were analysed using IBM SPSS Statistics 28.0, and Fisher’s Exact Test was employed to compare differences within self-identified ethnicity groups and gender.

Results
Whilst most respondents felt prepared to care for patients in general (80.5%), many felt unprepared to care for specific ethnic patient cohorts, including patients from a minority ethnic background (50.7%) and the Irish Traveller Community (46.8%). Only 20.8% of final-year students felt they had received training in cross-cultural care during their time in medical school. Most respondents agreed that they should be assessed specifically on skills in cultural competence whilst in medical school (83.2%).

Conclusions
A large proportion of final-year medical students surveyed in Ireland feel inadequately prepared to care for ethnically diverse patients. Similarly, they report feeling unskilled in core areas of cross-cultural care, and a majority agree that they should be assessed on aspects of cultural competency. This study explores shortcomings in cultural competency training and confidence amongst Irish medical students. These findings have implications for future research and curricular change, with opportunities for the development of relevant educational initiatives in Irish medical schools.

Abstract
Background
Patient navigation is an evidence-based intervention that reduces cancer health disparities by directly addressing the barriers to care for underserved patients with cancer. Variability in design and integration of patient navigation programs within cancer care settings has limited this intervention’s utility. The implementation science evaluation framework, RE-AIM, allows quantitative and qualitative examination of effective implementation of patient navigation programs into cancer care settings.

Methods
The Reach, Effectiveness, Adoption, Implementation, and Maintenance (RE-AIM) framework was used to evaluate implementation of a community-focused patient navigation intervention at an NCI-designated cancer center between June 2018 and October 2021. Using a 3-month longitudinal, non-comparative measurement period, univariate and bivariate analyses were conducted to examine associations between participant-level demographics and primary (i.e., barrier reduction) and secondary (i.e., patient-reported outcomes) effectiveness outcomes. Mixed methods analyses were used to examine adoption and delivery of the intervention into the cancer center setting. Process-level analyses were used to evaluate maintenance of the intervention.

Results
Participants (n = 311) represented a largely underserved population, as defined by the National Cancer Institute, with the majority identifying as Hispanic/Latino, having a household income of $35,000 or less, and being enrolled in Medicaid. Participants were diagnosed with a variety of cancer types and most had advanced staged cancers. Pre-post-intervention analyses indicated significant reduction from pre-intervention assessments in the average number of reported barriers, F(1, 207) = 117.62, p < .001, as well as significant increases in patient-reported physical health, t(205) = − 6.004, p < .001, mental health, t(205) = − 3.810, p < .001, self-efficacy, t(205) = − 5.321, p < .001, and satisfaction with medical team communication, t(206) = − 2.03, p = .029. Referral patterns and qualitative data supported increased adoption and integration of the intervention into the target setting, and consistent intervention delivery metrics suggested high fidelity to intervention delivery over time. Process-level data outlined a successful transition from a grant-funded community-focused patient navigation intervention to an institution-funded program.

Conclusions
This study utilized the implementation science evaluation framework, RE-AIM, to evaluate implementation of a community-focused patient navigation program. Our analyses indicate successful implementation within a cancer care setting and provide a potential guide for other oncology settings who may be interested in implementing community-focused patient navigation programs.
Supporting first-time parents in their homes: an informal setting enabling interprofessional collaboration
Authors: Franzén Cecilia , Nilsson Eva-Lotta 
Published: April 2024

Abstract
Background
Home visiting programmes aiming to support parents and promote more equal health amongst young children have grown in Sweden and in other countries. These programmes involve interprofessional teams. Teamwork in interprofessional contexts often requires setting boundaries, but professionals’ boundary work in the home setting is unexplored. Therefore, this article focuses on interprofessional teams comprising child healthcare nurses, midwives, social workers, and dental hygienists in a home visiting programme for first-time parents in Sweden; it aims to explore how the professionals performed boundary work that enabled collaboration and to investigate important contextual conditions for this kind of boundary work.

Methods
The data were drawn from semi-structured interviews with twelve professionals from the four different disciplines. Content analysis was used to explore their boundary work.

Results
The findings show that the professionals performed three forms of collaborative boundary work. They maintained boundaries by clarifying their distinct roles and expertise. However, the differences were viewed as complementary, and the professionals worked together humbly to complement each other’s knowledge and perspectives. Lastly, they tended to drop perceptions of prestige and blurred the boundaries to accommodate their overlapping knowledge. Important conditions for the success of collaborative boundary work were meetings prior to the home visits, the opportunities for discussion and reflection after the home visits, and the informal character of the home setting. Consequently, the professionals were able to jointly contribute to a holistic view of the visited families, which increased the possibilities to meet these families’ needs.

Conclusions
This study contributes knowledge on boundary work in interprofessional collaborations in the home setting. The informal character of the home setting seemed to facilitate collaboration and contributed to creating informal professional roles. The findings suggest that having interprofessional teams in the home setting enabled collaboration as well as reinforced support for first-time parents, which emphasizes the merit of home visit programmes.

Published: April 2024

Abstract
Background
The Warburg effect is a hallmark characteristic of colorectal cancer (CRC). Despite extensive research, the role of long non-coding RNAs (lncRNAs) in influencing the Warburg effect remains incompletely understood. Our study aims to identify lncRNAs that may modulate the Warburg effect by functioning as competing endogenous RNAs (ceRNAs).

Methods
Utilizing bioinformatics approaches, we extracted glycolysis-associated gene data from the Kyoto Encyclopedia of Genes and Genomes (KEGG) and identified 101 glycolysis-related lncRNAs in CRC. We employed Univariable Cox regression, Least Absolute Shrinkage and Selection Operator (LASSO) regression analysis, and Multivariable Cox regression to develop a prognostic model comprising four glycolysis-linked lncRNAs. We then constructed a prognostic nomogram integrating this lncRNA model with other relevant clinical parameters.

Results
The prognostic efficacy of our four-lncRNA signature and its associated nomogram was validated in both training and validation cohorts. Functional assays demonstrated significant glycolysis and hexokinase II (HK2) inhibition following the silencing of RUNDC3A − AS1, a key lncRNA in our prognostic signature, highlighting its regulatory importance in the Warburg effect.

Conclusions
Our research illuminates the critical role of glycolysis-centric lncRNAs in CRC. The developed prognostic model and nomogram underscore the pivotal prognostic and regulatory significance of the lncRNA RUNDC3A − AS1 in the Warburg effect in colorectal cancer.

AbstractObjectivesThe risk of intracranial aneurysms (IAs) development and rupture is significantly higher in patients with periodontitis (PD), suggesting an association between the two. However, the specific mechanisms of association between these two diseases have not been fully investigated.Materials and methodsIn this study, we downloaded IAs and PD data from the Gene Expression Omnibus. Differentially expressed genes (DEGs) were identified, and functional enrichment analysis was performed. The protein-protein interaction (PPI) network and weighted gene co-expression network analysis (WGCNA) was performed to identified key modules and key crosstalk genes. In addition, the immune cell landscape was assessed and the correlation of key crosstalk genes with each immune cell was calculated. Finally, transcription factors (TFs) regulating key crosstalk genes were explored.Results127 overlapping DEGs were identified and functional enrichment analysis highlighted the important role of immune reflection in the pathogenesis of IAs and PD. We identified ITGAX and COL4A2 as key crosstalk genes. In addition, the expression of multiple immune cells was significantly elevated in PDs and IAs compared to controls, and both key crosstalk genes were significantly negatively associated with Macrophages M2. Finally, GATA2 was identified as a potential key transcription factor (TF), which regulates two key crosstalk gene.ConclusionsThe present study identifies key crosstalk genes and TF in PD and IAs, providing new insights for further study of the co-pathogenesis of PD and IAs from an immune and inflammatory perspective. Also, this is the first study to report the above findings.

Abstract
Introduction
Introduction: Malaria continues to be the leading cause of hospitalization and death in Angola, a country in sub-
Saharan Africa. In 2023, in the first quarter, 2,744,682 cases were registered, and of these 2,673 patients died
due to malaria disease. Previous studies have shown that the ABO blood group can affect the progression of
malaria to severe conditions after P. falciparum infection, while the sickle cell gene offers relative protection.

Objective
We investigated changes in the blood count according to blood groups (ABO/Rh) and sickle cell
trait in patients with malaria in Luanda, capital of Angola.

Methodology
This was a longitudinal, prospective
and observational study with 198 patients hospitalized for malaria.

Results
Of the 198 patients studied,
13(6.6%) were ABRh(+), 4(2.0%) were ARh(-), 49(24.7%) were ARh(+), 42(21, 2%) were BRh (+), 5(2.5%)
were ORh(-) and 85(42.9%) were ORh(+). For sickle cell trait, 145(73.2%) were AA, 37(18.7%) were AS and
16(8.1%) were SS. No statistical relationship was observed between age group, sex, parasitemia, clinical
picture, hematocrit, MCV, HCM, MCHC, leukocytes, NEUT, LINF and PTL values with blood groups
(p<0.05), but there was a relationship between values of hemoglobin and ABO/Rh blood groups (p>0.05).
There was no relationship between age, parasitemia, clinical condition, MCV, HCM and MCHC values,
leukocytes, NEUT and LINF with sickle cell trait (p<0.05), but there was a relationship between sex,
hemoglobin and PTL and sickle cell values. sickle cell trait (p>0.05).

Conclusion
It is imperative to
differentiate patients with malaria based on blood groups and sickle cell trait, taking into account mainly the
blood count parameters that demonstrate that there are patients who, depending on blood group or sickle cell
trait, may react weakly to malaria infection regardless of the degree of parasitemia and medical prognosis.
Chinese visceral adiposity index and its transition patterns: impact on cardiovascular and cerebrovascular diseases in a national cohort study

Published: April 2024

Abstract
Background
Obesity affects approximately 800 million people worldwide and may contribute to various diseases, especially cardiovascular and cerebrovascular conditions. Fat distribution and content represent two related yet distinct axes determining the impact of adipose tissue on health. Unlike traditional fat measurement indices, which often overlook fat distribution, the Chinese visceral adiposity index (CVAI) is a novel metric used to assess visceral fat accumulation and associated health risks. Our objective is to evaluate its association with the risk of cardiovascular and cerebrovascular diseases.

Methods
A nationwide longitudinal study spanning 9 years was conducted to investigate both the effects of baseline CVAI levels (classified as low and high) and dynamic changes in CVAI over time, including maintenance of low CVAI, transition from low to high, transition from high to low, and maintenance of high CVAI. Continuous scales (restricted cubic spline curves) and categorical scales (Kaplan-Meier curves and multivariable Cox regression analyses) were utilized to evaluate the relationship between CVAI and cardiovascular and cerebrovascular diseases. Furthermore, subgroup analyses were conducted to investigate potential variations.

Results
Totally 1761 individuals (22.82%) experienced primary outcomes among 7717 participants. In the fully adjusted model, for each standard deviation increase in CVAI, there was a significant increase in the risk of primary outcomes [1.20 (95%CI: 1.14–1.27)], particularly pronounced in the high CVAI group [1.38 (95%CI: 1.25–1.54)] compared to low CVAI group. Regarding transition patterns, individuals who consistently maintained high CVAI demonstrated the highest risk ratio compared to those who consistently maintained low CVAI [1.51 (95%CI: 1.31–1.74)], followed by individuals transitioning from low to high CVAI [1.22 (95% CI: 1.01–1.47)]. Analysis of restricted cubic spline curves indicated a positive dose-response relationship between CVAI and risk of primary outcomes (p for non-linear = 0.596). Subgroup analyses results suggest that middle-aged individuals with high CVAI face a notably greater risk of cardiovascular and cerebrovascular diseases in contrast to elderly individuals [1.75 (95% CI: 1.53–1.99)].

Conclusion
This study validates a significant association between baseline levels of CVAI and its dynamic changes with the risk of cardiovascular and cerebrovascular diseases. Vigilant monitoring and effective management of CVAI significantly contribute to early prevention and risk stratification of cardiovascular and cerebrovascular diseases.
Lipid peroxidation-induced ferroptosis as a therapeutic target for mitigating neuronal injury and inflammation in sepsis-associated encephalopathy: insights into the hippocampal PEBP-1/15-LOX/GPX4 pathway
Authors: Wang Haosen , Xu Lixiao , Tang Xiaojuan , Jiang Zhen , Feng Xing 
Published: April 2024

Abstract
Background
Sepsis-associated encephalopathy (SAE) refers to the widespread impairment of brain function caused by noncentral nervous system infection mediated by sepsis. Lipid peroxidation-induced ferroptosis contributes to the occurrence and course of SAE. This study aimed to investigate the relationship between neuronal injury and lipid peroxidation-induced ferroptosis in SAE.

Methods
Baseline data were collected from pediatric patients upon admission, and the expression levels of various markers related to lipid peroxidation and ferroptosis were monitored in the serum and peripheral blood mononuclear cells (PBMCs) of patients with SAE as well as SAE model mice. The hippocampal phosphatidylethanolamine-binding protein (PEBP)-1/15-lysine oxidase (LOX)/ glutathione peroxidase 4 (GPX4) pathway was assessed for its role on the inhibitory effect of ferroptosis in SAE treatment.

Results
The results showed elevated levels of S100 calcium-binding protein beta (S-100β), glial fibrillary acidic protein, and malondialdehyde in the serum of SAE patients, while superoxide dismutase levels were reduced. Furthermore, analysis of PBMCs revealed increased transcription levels of PEBP1, LOX, and long-chain fatty acyl-CoA synthetase family member 4 (ACSL4) in SAE patients, while the transcription levels of GPX4 and cystine/glutamate transporter xCT (SLC7A11) were decreased. In comparison to the control group, the SAE mice exhibited increased expression of S-100β and neuron-specific enolase (NSE) in the hippocampus, whereas the expression of S-100β and NSE were reduced in deferoxamine (DFO) mice. Additionally, iron accumulation was observed in the hippocampus of SAE mice, while the iron ion levels were reduced in the DFO mice. Inhibition of ferroptosis alleviated the mitochondrial damage (as assessed by transmission electron microscopy, hippocampal mitochondrial ATP detection, and the JC-1 polymer-to-monomer ratio in the hippocampus) and the oxidative stress response induced by SAE as well as attenuated neuroinflammatory reactions. Further investigations revealed that the mechanism underlying the inhibitory effect of ferroptosis in SAE treatment is associated with the hippocampal PEBP-1/15-LOX/GPX4 pathway.

Conclusion
These results offer potential therapeutic targets for the management of neuronal injury in SAE and valuable insights into the potential mechanisms of ferroptosis in neurological disorders.

Published: April 2024

Abstract
Background
Dimethyl fumarate (DMF) is a fumaric acid ester that exhibits immunoregulatory and anti-inflammatory properties. However, the function of DMF in autoimmune uveitis (AU) is incompletely understood, and studies comprehensively exploring the impact of DMF on immune cells are still lacking.

Methods
To explore the function of DMF in uveitis and its underlying mechanisms, we conducted single-cell RNA sequencing (scRNA-seq) on the cervical draining lymph node (CDLN) cells of normal, experimental autoimmune uveitis (EAU), and DMF-treated EAU mice. Additionally, we integrated scRNA-seq data of the retina and CDLNs to identify the potential impact of DMF on ocular immune cell infiltration. Flow cytometry was conducted to verify the potential target molecules of DMF.

Results
Our study showed that DMF treatment effectively ameliorated EAU symptoms. The proportional and transcriptional alterations in each immune cell type during EAU were reversed by DMF treatment. Bioinformatics analysis in our study indicated that the enhanced expression of Pim1 and Cxcr4 in EAU was reversed by DMF treatment. Further experiments demonstrated that DMF restored the balance between effector T (Teff) /regulatory T (Treg) cells through inhibiting the pathway of PIM1-protein kinase B (AKT)-Forkhead box O1 (FOXO1). By incorporating the scRNA-seq data of the retina from EAU mice into analysis, our study identified that T cells highly expressing Pim1 and Cxcr4 were enriched in the retina. DMF repressed the ocular infiltration of Teff cells, and this effect might depend on its inhibition of PIM1 and CXCR4 expression. Additionally, our study indicated that DMF might reduce the proportion of plasma cells by inhibiting PIM1 expression in B cells.

Conclusions
DMF effectively attenuated EAU symptoms. During EAU, DMF reversed the Teff/Treg cell imbalance and suppressed the ocular infiltration of Teff cells by inhibiting PIM1 and CXCR4 expression. Thus, DMF may act as a new drug option for the treatment of AU.

Published: April 2024

AbstractPrevious studies have shown that the three-dimensional (3D) geometric and electronic structure of molecules play a crucial role in determining their key properties and intermolecular interactions. Therefore, it is necessary to establish a quantum chemical (QC) property database containing the most stable 3D geometric conformations and electronic structures of molecules. In this study, a high-quality QC property database, called QuanDB, was developed, which included structurally diverse molecular entities and featured a user-friendly interface. Currently, QuanDB contains 154,610 compounds sourced from public databases and scientific literature, with 10,125 scaffolds. The elemental composition comprises nine elements: H, C, O, N, P, S, F, Cl, and Br. For each molecule, QuanDB provides 53 global and 5 local QC properties and the most stable 3D conformation. These properties are divided into three categories: geometric structure, electronic structure, and thermodynamics. Geometric structure optimization and single point energy calculation at the theoretical level of B3LYP-D3(BJ)/6-311G(d)/SMD/water and B3LYP-D3(BJ)/def2-TZVP/SMD/water, respectively, were applied to ensure highly accurate calculations of QC properties, with the computational cost exceeding 107 core-hours. QuanDB provides high-value geometric and electronic structure information for use in molecular representation models, which are critical for machine-learning-based molecular design, thereby contributing to a comprehensive description of the chemical compound space. As a new high-quality dataset for QC properties, QuanDB is expected to become a benchmark tool for the training and optimization of machine learning models, thus further advancing the development of novel drugs and materials.
