BACKGROUND
Coronary access (CA) is a major concern in redo-transcatheter aortic valve implantation (TAVI) for failing supra-annular self-expanding transcatheter aortic valves (TAVs).
AIMS
This ex vivo study evaluated the benefit of leaflet splitting (LS) on subsequent CA after redo-TAVI in anatomies deemed at high risk of unfeasible CA.
METHODS
Ex vivo, patient-specific models were printed three-dimensionally. Index TAVI was performed using ACURATE neo2 or Evolut PRO (TAV-1) at the standard implant depth and with different degrees of commissural misalignment (CMA). Redo-TAVI was performed using the balloon-expandable SAPIEN 3 Ultra (TAV-2) at different implant depths with commissural alignment. Selective CA was attempted for each configuration before and after LS in a pulsatile flow simulator. The leaflet splay area was assessed on the bench.
RESULTS
In matched comparisons of 128 coronary cannulations across 64 redo-TAVI configurations, the overall feasibility of CA significantly increased after LS (60.9% vs 18.7%; p<0.001). The effect of LS varied according to the sinotubular junction height, TAV-1 design, TAV-1 CMA, and TAV-2 implant depth, given TAV-2 alignment. LS enabled CA for up to CMA 45° with the ACURATE neo2 TAV-1 and up to CMA 30° with the Evolut PRO TAV-1. The combination of LS and a low TAV-2 implant provided the highest feasibility of CA after redo-TAVI. The leaflet splay area ranged from 25.60 mm2 to 37.86 mm2 depending on the TAV-1 platform and TAV-2 implant depth.
CONCLUSIONS
In high-risk anatomies, LS significantly improves CA feasibility after redo-TAVI for degenerated supra-annular self-expanding platforms. Decisions on redo-TAVI feasibility should be carefully individualised, taking into account the expected benefit of LS on CA for each scenario.

BACKGROUND
The human rights of dental hygiene students should be guaranteed during practice at medical institutions for their mental and physical health as well as professionalism, for patient safety. Safe and well guaranteed clinicians can perform their work in a more stable way. This study investigated the human rights circumstances of dental hygiene students during their hospital clinical practice at dental institutions.
METHODS
This study used a cross-sectional survey design. Convenience sampling was conducted on 121 third- and fourth-year dental hygiene students from universities in Seoul, Gyeonggi, and Gangwon. The survey used the Human Rights Indicators for Dental Hygiene Students to investigate the rights to safety, equality, and personality to understand participants' experiences of guaranteed fundamental rights. Data were collected from October 31 to November 8, 2019. A chi-square test was used to assess differences in experience according to general characteristics.
RESULTS
During dental hygiene practice at dental institutions, less than 50% of students felt safe. When human rights violations occurred in dental institutions, only 42.4% of students received guidance on response measures from their universities. While 72.1% of students who practiced at dental university hospitals were given information on first aid supplies (facilities) within dental institutions, only approximately 45% of students who practiced at lower-scale dental institutions were given this information (p < 0.05). Regarding equality rights, only 52.5% of trainees reported that they had received equal treatment from healthcare workers during hospital clinical practice.
CONCLUSIONS
During dental practice at dental institutions, Korean dental hygiene students confirmed that human rights (including safety rights, equality rights, and personality rights) were guaranteed to varying degrees. Dental hygiene students' rights during hospital clinical practice in dental institutions should be guaranteed across institutions regardless of their scale. This is necessary for dental hygiene students' human rights and safe policies and guidelines in dental institution clinical practice and regular monitoring systems.

BACKGROUND
Recognizing patients' rights as fundamental human rights, the global healthcare community, including the World Health Organization and various nursing organizations, has emphasized the critical role of nurses in upholding these rights through ethical practice and patient-centered care. However, in the complex landscape of healthcare, nurses in Vietnam face various ethical issues and challenges that may impede their ability to protect patient rights effectively, necessitating tools for better ethical decision-making and practice.
PURPOSE
This study aims to translate the Nurses' Ethical Behaviours for Protecting Patient Rights Scale (NEBPPR) into Vietnamese and evaluate the validity and reliability of the V-NEBPPRS.
METHODS
The original scale underwent a cross-cultural translation process to be adapted into Vietnamese. Construct validity was assessed using confirmatory factor analysis (CFA). The convergent validity, discriminant validity, and reliability of the V-NEBPPRS were evaluated.
RESULTS
After removing four items with factor loading below 0.5, the V-NEBPPRS comprises 24 items divided into five factors. CFA demonstrated a good model fit (χ2/df = 2.86; GFI = 0.87; IFI = 0.85; CFI = 0.84; RMSEA = 0.07). Convergent and discriminant validity were confirmed with extracted mean variance ranging from 0.54 to 0.67, 0.54 to 0.67, and composite reliability from 0.73 to 0.81. Cronbach's α coefficient was 0.85 for the total scale and ranged from 0.70 to 0.79 for five subscales.
CONCLUSION
The V-NEBPPRS is a reliable tool, providing nursing leaders and researchers with the means to utilize the V-NEBPPRS for assessing and promoting nurses' awareness and behaviour in safeguarding patients' rights, thereby contributing to improved overall health outcomes.

BACKGROUND
Artificial intelligence (AI) has become a pivotal tool in advancing contemporary personalised medicine, with the goal of tailoring treatments to individual patient conditions. This has heightened the demand for access to diverse data from clinical practice and daily life for research, posing challenges due to the sensitive nature of medical information, including genetics and health conditions. Regulations like the Health Insurance Portability and Accountability Act (HIPAA) in the U.S. and the General Data Protection Regulation (GDPR) in Europe aim to strike a balance between data security, privacy, and the imperative for access.
RESULTS
We present the Gemelli Generator - Real World Data (GEN-RWD) Sandbox, a modular multi-agent platform designed for distributed analytics in healthcare. Its primary objective is to empower external researchers to leverage hospital data while upholding privacy and ownership, obviating the need for direct data sharing. Docker compatibility adds an extra layer of flexibility, and scalability is assured through modular design, facilitating combinations of Proxy and Processor modules with various graphical interfaces. Security and reliability are reinforced through components like Identity and Access Management (IAM) agent, and a Blockchain-based notarisation module. Certification processes verify the identities of information senders and receivers.
CONCLUSIONS
The GEN-RWD Sandbox architecture achieves a good level of usability while ensuring a blend of flexibility, scalability, and security. Featuring a user-friendly graphical interface catering to diverse technical expertise, its external accessibility enables personnel outside the hospital to use the platform. Overall, the GEN-RWD Sandbox emerges as a comprehensive solution for healthcare distributed analytics, maintaining a delicate equilibrium between accessibility, scalability, and security.

BACKGROUND
Transcultural nursing recognises the significance of cultural backgrounds in providing patients with quality care. This study investigates the opinions of master's students in nursing and midwifery regarding the attitudes of Jehovah's Witnesses towards refusing blood transfusions.
METHODS
349 master's students in nursing and midwifery participated in a quantitative study and were surveyed via the Web to evaluate their awareness of the stance of Jehovah's Witnesses on blood transfusions and the ethical and legal dilemmas associated with caring for Jehovah's Witness (JW) patients.
RESULTS
The study yielded three significant findings. It unequivocally demonstrates that nursing and midwifery students possess inadequate knowledge regarding Jehovah's Witnesses' stance on blood transfusions and their acceptance of specific blood products and medical procedures. Despite being cognisant of the ethical and legal dilemmas of caring for JW patients, students lack an understanding of patients' autonomy to reject blood transfusions and their need for bloodless medicine. Students also articulated educational needs regarding cultural competencies regarding the Jehovah's Witnesses' beliefs on blood transfusions and non-blood management techniques.
CONCLUSIONS
Healthcare professionals need the knowledge and skills necessary to provide holistic, patient-centred and culturally sensitive care. This study emphasises the urgent need for university curricula and nursing postgraduate training to include modules on transcultural nursing and strategies for minimising blood loss.

INTRODUCTION
Stump syndrome is defined as a clinical syndrome resulting from a distal intracranial vessel embolic stroke due to an extracranial vessel occlusion. Similar to the anterior circulation, the recurrence of ischemic strokes in territories supplied by the posterior circulation in the presence of vertebral artery occlusion is termed Vertebral Artery Stump Syndrome (VASS).
MATERIAL AND METHODS
We conducted a literature review, identifying 72 patients with transient ischemic attacks (TIAs) or ischemic strokes attributed to VASS, according to Kawano criteria. We categorized all patients in two groups focusing on the therapeutic management those who underwent primary medical treatment and those who received endovascular or surgical treatment either in acute or chronic phase.
RESULTS
In the anticoagulant therapy group, only 1 patient had a stroke recurrence. Among the 4 on antiplatelets, all had recurrences, but 3 benefited from switching to anticoagulants or endovascular therapy. In the endovascular therapy group, worse outcomes were linked to acute large vessel occlusion. Endovascular treatment of the vertebral artery, in a chronic phase, was explored in literature for recurrent TIAs or minor strokes suggesting that this could be a viable therapeutic alternative when medical treatment failed in preventing recurrence of ischemic stroke.
CONCLUSIONS
Some studies suggest that anticoagulant medical therapy may be beneficial for VASS and endovascular therapy has also been reported for selected patients. However, data on treatment outcomes and prognosis are still underreported, making treatment decisions challenging. Randomized Controlled Trials are needed to establish the optimal treatment approach.

BACKGROUND
Consider a setting where multiple parties holding sensitive data aim to collaboratively learn population level statistics, but pooling the sensitive data sets is not possible due to privacy concerns and parties are unable to engage in centrally coordinated joint computation. We study the feasibility of combining privacy preserving synthetic data sets in place of the original data for collaborative learning on real-world health data from the UK Biobank.
METHODS
We perform an empirical evaluation based on an existing prospective cohort study from the literature. Multiple parties were simulated by splitting the UK Biobank cohort along assessment centers, for which we generate synthetic data using differentially private generative modelling techniques. We then apply the original study's Poisson regression analysis on the combined synthetic data sets and evaluate the effects of 1) the size of local data set, 2) the number of participating parties, and 3) local shifts in distributions, on the obtained likelihood scores.
RESULTS
We discover that parties engaging in the collaborative learning via shared synthetic data obtain more accurate estimates of the regression parameters compared to using only their local data. This finding extends to the difficult case of small heterogeneous data sets. Furthermore, the more parties participate, the larger and more consistent the improvements become up to a certain limit. Finally, we find that data sharing can especially help parties whose data contain underrepresented groups to perform better-adjusted analysis for said groups.
CONCLUSIONS
Based on our results we conclude that sharing of synthetic data is a viable method for enabling learning from sensitive data without violating privacy constraints even if individual data sets are small or do not represent the overall population well. Lack of access to distributed sensitive data is often a bottleneck in biomedical research, which our study shows can be alleviated with privacy-preserving collaborative learning methods.

After the first COVID-19 vaccines received emergency use authorization from the U.S. FDA in December 2020, U.S. states employed vaccine eligibility and administration plans (VEAPs) that determined when subgroups of residents would become eligible to receive the vaccine while the vaccine supply was still limited. During the implementation of these plans, public concern grew over whether the VEAPs and vaccine allocations from the federal government were resulting in an equitable and efficient vaccine distribution. In this study, we collected data on five states' VEAPs, federal vaccine allocations, vaccine administration, and vaccine hesitancy to assess the equity of vaccine access and vaccine administration efficiency that manifested during the campaign. Our results suggest that residents in states which opened eligibility to the vaccine sooner had more competition among residents to receive the vaccine than occurred in other states. Regardless of states' VEAPs, there was a consistent inefficiency in vaccine administration among all five states that could be attributed to both state and federal infrastructure deficits. A closer examination revealed a misalignment between federal vaccine allocations and the total eligible population in the states throughout the campaign, even when accounting for hesitancy. We conclude that in order to maximize the efficiency of future mass-vaccination campaigns, the federal and state governments should design adaptable allocation policies and eligibility plans that better match the true, real-time supply and demand for vaccines by accounting for vaccine hesitancy and manufacturing capacity. Further, we discuss the challenges of implementing such strategies.

Review
Increased use of whole genome sequencing (WGS) in neuro-oncology for diagnostics and research purposes necessitates a renewed conversation about informed consent procedures and governance structures for sharing personal health data. There is currently no consensus on how to obtain informed consent for WGS in this population. In this narrative review, we analyze the formats and contents of frameworks suggested in literature for WGS in oncology and assess their benefits and limitations. We discuss applicability, specific challenges, and legal context for patients with (recurrent) glioblastoma. This population is characterized by the rarity of the disease, extremely limited prognosis, and the correlation of the stage of the disease with cognitive abilities. Since this has implications for the informed consent procedure for WGS, we suggest that the content of informed consent should be tailor-made for (recurrent) glioblastoma patients.

Review
Genomic data holds huge potential for medical progress but requires strict safety measures due to its sensitive nature to comply with data protection laws. This conflict is especially pronounced in genome-wide association studies (GWAS) which rely on vast amounts of genomic data to improve medical diagnoses. To ensure both their benefits and sufficient data security, we propose a federated approach in combination with privacy-enhancing technologies utilising the findings from a systematic review on federated learning and legal regulations in general and applying these to GWAS.
