Published: June 2024

Abstract
Background
Crohn’s disease (CD)-associated periodontitis is common. However, the role of periodontal pathogens in the Coexistence of CD and periodontal disease remains unclear.

Methods
To investigate the potential relationship mediated by periodontal pathogens between periodontitis and CD, we collected salivary samples from healthy participants (H group, n = 12), patients with CD (Ch group, n = 10), patients with periodontitis (Ps group, n = 12), and patients with Coexistence of CD and periodontal disease (Cp group, n = 12) and analyzed them by 16 S rRNA sequencing.

Results
Patients with Coexistence of CD and periodontal disease had increased levels of Fusobacterium, Actinomyces, Leptotrichia, and Prevotella, which correlated with the severity of periodontitis. Conversely, the levels of Streptococcus, Neisseria, Haemophilus, and Gemella, which decreased in Coexistence of CD and periodontal disease, were negatively correlated with the severity of periodontitis. To further investigate the role of periodontal pathogens in CD development, representative periodontal pathogens causing periodontitis, Porphyromonas gingivalis and Fusobacterium nucleatum, were administered to mice. These pathogens migrate to, and colonize, the gut, accelerating CD progression and aggravating colitis, and even systemic inflammation. In vitro experiments using a Caco-2/periodontal pathogen coculture revealed that P. gingivalis and F. nucleatum increased intestinal permeability by directly disrupting the tight junctions of intestinal epithelial cells.

Conclusion
Our findings strongly suggest that periodontal pathogens play a role in the relationship between periodontitis and CD. These results provide a basis for understanding the pathogenesis of Coexistence of CD and periodontal disease and may lead to the development of novel therapeutic strategies.
Dignity enhanced through faith & family support in palliative care: a qualitative study
Authors: Sailian Silva Dakessian , Salifu Yakubu , Preston Nancy 
Published: June 2024

Abstract
Background
Dignity is integral to palliative care. Illness can diminish it, causing hopelessness and the wish to hasten death. Yet, dignity is a complex multidimensional phenomenon, influenced by values and context. Understanding its varying interpretations can inform practice and policy. The aim of the study is to explore the understanding of dignity in adult patients with palliative care needs from a Lebanese perspective and how it is preserved during illness and while receiving health services.

Design
Qualitative interview study underpinned with a social constructionist lens. Fourteen patients recruited from home-based hospice and outpatient clinics in Lebanon. Data analysed using reflexive thematic analysis.

Results
Four themes were developed across all the interviews: (a) Dignity anchored through faith in God and religious practices; (b) Family support in maintaining physical, psychological wellbeing, and social connectedness; (c) Physical fitness, mental acuity, and healthy appearance through which patients may escape the stigma of disease, (d) accessible, equitable, and compassionate healthcare.

Discussion
Dignity is elusive and difficult to define but faith and religious beliefs play a significant contribution in this study. For the participants, illness is seen as a natural part of life that does not necessarily diminish dignity, but it is the illness related changes that potentially affect dignity. Findings show the importance of family and children in preserving dignity during illness and how their active presence provide a sense of pride and identity. Participants aspired to restore physical, social, and mental well-being to reclaim their dignity and normalize their lives. Challenges related to physical appearance, memory loss, vitality, and social stigma associated with illness diminished dignity. Accessible, equitable and compassionate healthcare services are also crucial in preserving dignity. Participants valued clear communication, respect, and empathy from healthcare providers and identified affordability of care essential for maintaining dignity.

Conclusion
Faith in God, and strong family ties are dominant elements to maintaining dignity in the Lebanese context. Relational connectedness with family, children or God is also a need in maintaining dignity in other communal countries with variations in emphasis. The study indicates that religious and cultural context shapes the needs and perceptions of dignity during illness. These findings are likely to be transferable to many Middle Eastern countries but also countries with strong religious and family ties globally.

Authors: Hamzah Khadijahtul Qubra Amizah , Mohd Zulkefli Nor Afiah , Ahmad Norliza 
Published: June 2024

Abstract
Background
Urban poor women face dual challenges regarding gender inequalities and urban poverty, which make them more likely to have health problems and affect their health-seeking behaviour. This study aimed to determine the prevalence of health-seeking behaviour during times of illness and predictors of sought care among urban poor women in Kuala Lumpur, Malaysia.

Methods
This cross-sectional study was performed among 340 randomly selected women residents from April to May 2023. Data was collected using a validated and reliable self-administered questionnaire and analysed using SPSS version 28.0 software. The dependent variable in this study was health-seeking behaviour during times of illness, while the independent variables were sociodemographic characteristics, socioeconomic characteristics, medical conditions, women’s autonomy in decision-making, social support, perceived stigma, and attitude towards health. Multiple logistic regression was used to identify the predictors of sought care during times of illness.

Results
Study response rate was 100%, where 72.4% sought care during times of illness. Being non-Malay (AOR = 4.33, 95% CI: 1.847, 10.161), having healthcare coverage (AOR = 2.60, 95% CI: 1.466, 4.612), rating their health as good (AOR = 1.87, 95% CI: 1.119, 3.118), and having pre-existing chronic diseases (AOR = 1.92, 95% CI: 1.130, 3.271) were identified as predictors of sought care during times of illness.

Conclusion
The present study showed that health-seeking behaviour during times of illness among the participants was appropriate. Health promotion and education, with a focus on educating and raising awareness about the importance of seeking timely healthcare, are crucial to improving health-seeking behaviour among urban poor women. Collaboration with relevant stakeholders is needed to develop comprehensive strategies to improve access to healthcare facilities for these women.

Published: June 2024

Abstract
Objectives
This study aims to analyze factors associated with positive surgical margins following cold knife conization (CKC) in patients with cervical high-grade squamous intraepithelial lesion (HSIL) and to develop a machine-learning-based risk prediction model.

Method
We conducted a retrospective analysis of 3,343 patients who underwent CKC for HSIL at our institution. Logistic regression was employed to examine the relationship between demographic and pathological characteristics and the occurrence of positive surgical margins. Various machine learning methods were then applied to construct and evaluate the performance of the risk prediction model.

Results
The overall rate of positive surgical margins was 12.9%. Independent risk factors identified included glandular involvement (OR = 1.716, 95% CI: 1.345–2.189), transformation zone III (OR = 2.838, 95% CI: 2.258–3.568), HPV16/18 infection (OR = 2.863, 95% CI: 2.247–3.648), multiple HR-HPV infections (OR = 1.930, 95% CI: 1.537–2.425), TCT ≥ ASC-H (OR = 3.251, 95% CI: 2.584–4.091), and lesions covering ≥ 3 quadrants (OR = 3.264, 95% CI: 2.593–4.110). Logistic regression demonstrated the best prediction performance, with an accuracy of 74.7%, sensitivity of 76.7%, specificity of 74.4%, and AUC of 0.826.

Conclusion
Independent risk factors for positive margins after CKC include HPV16/18 infection, multiple HR-HPV infections, glandular involvement, extensive lesion coverage, high TCT grades, and involvement of transformation zone III. The logistic regression model provides a robust and clinically valuable tool for predicting the risk of positive margins, guiding clinical decisions and patient management post-CKC.

Authors: Choi Yiseul , Lee Myoungho , Kim Jaeyeon , Park Wonse 
Published: June 2024

Abstract
Background
Clinical observation conducted during the 3rd and 4th years of dental school is an important part of dental students’ clinical education. However, conventional clinical observation is associated with several problems, including the lack of opportunity for all students to assist during surgery. Virtual reality (VR) technologies and devices can be used to demonstrate clinical processes that dental students need to learn through clinical observation. This study aimed to evaluate the effectiveness of teaching dental students the surgical tooth extraction procedure through clinical observation using VR.

Methods
We recruited third- and fourth-year dental students and divided them into a VR clinical observation group (VR group) and a conventional clinical observation group (control group). The control group visited an outpatient clinic and observed an oral and maxillofacial specialist perform surgical tooth extraction, whereas the VR group watched a 360° video of surgical tooth extraction using a head-mounted display. After observation, both groups were surveyed regarding their satisfaction with the clinical observation and their understanding of the procedure.

Results
Understanding of the procedure and satisfaction with the observation were significantly higher in the VR group than in the control group (p = 0.001 and p = 0.047, respectively). Compared with conventional clinical observation, VR clinical observation improved learning motivation and medical thinking and judgment skills; however, interaction between professors and students was lacking.

Conclusions
VR clinical observation using 360° videos might be an effective teaching method for students. However, to allow interaction between professors and students during clinical observations, using it along with conventional clinical observation is necessary.

Authors: L. Neil Kara , Umucyo Deborah , Binagwaho Agnes , Waka Tsion Yohannes 
Published: June 2024

Abstract
Background
While Sub-Saharan Africa contains nearly one third of the global burden of disease, it only contains 3.5% of the healthcare workforce. Furthermore, female medical doctors are underrepresented across the continent. Studies show that increasing gender representation in medicine not only bridges this gap but may have a positive impact on patient care. This study explores the support systems influencing female students to pursue medical school in Rwanda, aiming to recommend ways to increase female participation through support systems.

Methods
This is an exploratory, interpretive study employing qualitative methods. The study was conducted at thirteen secondary schools within two provinces and three universities in Rwanda that offer a medical degree program. Participants were divided into focus groups, including female and male secondary students in science and non-science combinations; teachers of secondary students; female and male students enrolled in medical school; and parents of secondary students in science and non-science combinations. Private and public, mixed and girls-only secondary schools that met the criteria were selected in each province, and all universities offering a medical degree. Participants were selected via random stratified sampling. Thirty-four semi-structured focus group discussions were conducted (28 secondary-level and 6 university-level) and 16 interviews. Data was coded inductively, with common themes identified.

Results
Four main themes were identified as support systems that can either serve as facilitators or barriers to pursuing an MBBS, including teacher support, parental or familial support, financial or institutional policy support, and having access to female mentors or role models.

Conclusion
Social support systems are enablers encouraging female students to join medical school. Integrating social support systems in schools and the community has the potential to increase female applicants to medical school in Rwanda.

Published: June 2024

AbstractBackgroundThe rapid growth of artificial intelligence (AI) technologies has been driven by the latest advances in computing power. Although, there exists a dearth of research on the application of AI in medical education.Methodsthis study is based on the TAM-ISSM-UTAUT model and introduces STARA awareness and chilling effect as moderating variables. A total of 657 valid questionnaires were collected from students of a medical university in Dalian, China, and data were statistically described using SPSS version 26, Amos 3.0 software was used to validate the research model, as well as moderated effects analysis using Process (3.3.1) software, and Origin (2021) software.ResultsThe findings reveal that both information quality and perceived usefulness are pivotal factors that positively influence the willingness to use AI products. It also uncovers the moderating influence of the chilling effect and STARA awareness.ConclusionsThis suggests that enhancing information quality can be a key strategy to encourage the widespread use of AI products. Furthermore, this investigation offers valuable insights into the intersection of medical education and AI use from the standpoint of medical students. This research may prove to be pertinent in shaping the promotion of Medical Education Intelligence in the future.
A novel higher performance nomogram based on explainable machine learning for predicting mortality risk in stroke patients within 30 days based on clinical features on the first day ICU admission
Authors: Chen Haoran , Yang Fengchun , Duan Yifan , Yang Lin , Li Jiao 
Published: June 2024

Abstract
Background
This study aimed to develop a higher performance nomogram based on explainable machine learning methods, and to predict the risk of death of stroke patients within 30 days based on clinical characteristics on the first day of intensive care units (ICU) admission.

Methods
Data relating to stroke patients were extracted from the Medical Information Marketplace of the Intensive Care (MIMIC) IV and III database. The LightGBM machine learning approach together with Shapely additive explanations (termed as explain machine learning, EML) was used to select clinical features and define cut-off points for the selected features. These selected features and cut-off points were then evaluated using the Cox proportional hazards regression model and Kaplan-Meier survival curves. Finally, logistic regression-based nomograms for predicting 30-day mortality of stroke patients were constructed using original variables and variables dichotomized by cut-off points, respectively. The performance of two nomograms were evaluated in overall and individual dimension.

Results
A total of 2982 stroke patients and 64 clinical features were included, and the 30-day mortality rate was 23.6% in the MIMIC-IV datasets. 10 variables (“sofa (sepsis-related organ failure assessment)”, “minimum glucose”, “maximum sodium”, “age”, “mean spo2 (blood oxygen saturation)”, “maximum temperature”, “maximum heart rate”, “minimum bun (blood urea nitrogen)”, “minimum wbc (white blood cells)” and “charlson comorbidity index”) and respective cut-off points were defined from the EML. In the Cox proportional hazards regression model (Cox regression) and Kaplan-Meier survival curves, after grouping stroke patients according to the cut-off point of each variable, patients belonging to the high-risk subgroup were associated with higher 30-day mortality than those in the low-risk subgroup. The evaluation of nomograms found that the EML-based nomogram not only outperformed the conventional nomogram in NIR (net reclassification index), brier score and clinical net benefits in overall dimension, but also significant improved in individual dimension especially for low “maximum temperature” patients.

Conclusions
The 10 selected first-day ICU admission clinical features require greater attention for stroke patients. And the nomogram based on explainable machine learning will have greater clinical application.

Abstract
Aim
This study aimed to investigate the influence of green transformational leadership educational intervention on nurse managers’ green behavior and creativity.

Background
Organizational creativity is greatly influenced by leaders and their personality attributes. Additionally, innovative employee behavior is crucial for organizational performance and survival, which in turn promotes long-term organizational growth.

Method
A quasi-experimental design was conducted by using pre-test, post-test, and follow-up for a group that included 116 nurse managers who completed the intervention. Data were collected through the green transformational leadership knowledge questionnaire, green transformational leadership scale, green behavior questionnaire, and green creativity scale.

Results
Following the implementation of the Green Transformational Leadership educational intervention, there was an improvement in responses connected to the nurse manager’s use of green behavior and creativity. Three months after the intervention ended, the improvement was still present.

Conclusion
Nurse managers who had good knowledge about green transformational leadership showed increased green behavior and green creativity, which enhanced the organization’s success. This study showed the significance of developing and improving the skills of managerial creativity for the nurse supervisor of a hospital through training in transformational leadership.

Implications for nursing management
The concept of “green transformational leadership” refers to leadership behaviors and strategies aimed at promoting environmental sustainability and responsibility within an organization or a specific context. In the case we mentioned, it involves implementing educational interventions targeted at nurse managers to enhance their understanding and adoption of green practices, as well as fostering green behavior and creativity among them.

Published: June 2024

Abstract
Background
Nursing students encounter various stressors during their clinical practicum; however, the stressors are not the same during different periods. At present, studies on the stressors and coping styles of nursing students in the middle period of their clinical practicum are rare.

Aims
The current study aimed to explore the stressors and coping styles of nursing students in the middle period of their clinical practicum.

Methods
A qualitative study with a descriptive phenomenological method was conducted to collect data from 10 nursing students undergoing the middle period of their clinical practicum from December 2020 to February 2021. The data were collected by semistructured interviews using interview outlines prepared in advance. The data were analyzed by Colaizzi’s analysis method.

Results
The stressors experienced by nursing students in the middle period of their clinical practicum mainly included personal reasons, teaching arrangements, interpersonal relationships, occupational particularity and career planning. Additionally, nursing students coped with the stressors that they face in the clinical practicum by eliminating stressors and regulating emotions.

Conclusions
Nursing students experienced various stressors and used a variety of coping styles in the middle period of their clinical practicum, which was different from what occurred in the early and late periods. Targeted interventions should be formulated and implemented to relieve nursing students’ stress and guide them to adopt effective coping styles.
Novel insights into the potential applications of stem cells in pulmonary hypertension therapy
Authors: Guo Sijia , Wang^ Dachun 
Published: June 2024

AbstractPulmonary hypertension (PH) refers to a group of deadly lung diseases characterized by vascular lesions in the microvasculature and a progressive increase in pulmonary vascular resistance. The prevalence of PH has increased over time. Currently, the treatment options available for PH patients have limited efficacy, and none of them can fundamentally reverse pulmonary vascular remodeling. Stem cells represent an ideal seed with proven efficacy in clinical studies focusing on liver, cardiovascular, and nerve diseases. Since the potential therapeutic effect of mesenchymal stem cells (MSCs) on PH was first reported in 2006, many studies have demonstrated the efficacy of stem cells in PH animal models and suggested that stem cells can help slow the deterioration of lung tissue. Existing PH treatment studies basically focus on the paracrine action of stem cells, including protein regulation, exosome pathway, and cell signaling; however, the specific mechanisms have not yet been clarified. Apoptotic and afunctional pulmonary microvascular endothelial cells (PMVECs) and alveolar epithelial cells (AECs) are two fundamental promoters of PH although they have not been extensively studied by researchers. This review mainly focuses on the supportive communication and interaction between PMVECs and AECs as well as the potential restorative effect of stem cells on their injury. In the future, more studies are needed to prove these effects and explore more radical cures for PH.
