Chronic wounds, characterized by prolonged healing processes, pose a significant medical challenge with multifaceted aetiologies, including local and systemic factors. Here, it explores the complex pathogenesis of chronic wounds, emphasizing the disruption in the normal phases of wound healing, particularly the inflammatory phase, leading to an imbalance in extracellular matrix (ECM) dynamics and persistent inflammation. Senescent cell populations further contribute to impaired wound healing in chronic lesions. Traditional medical management focuses on addressing underlying causes, but many chronic wounds resist to conventional treatments, necessitating innovative approaches. Recent attention has turned to autologous orthobiologics, such as platelet-rich plasma (PRP), platelet-rich fibrin (PRF) and mesenchymal stem cells (MSCs), as potential regenerative interventions. These biologically derived materials, including bone marrow aspirate/concentrate (BMA/BMAC) and adipose tissue-derived stem cells (ADSCs), exhibit promising cytokine content and regenerative potential. MSCs, in particular, have emerged as key players in wound healing, influencing inflammation and promoting tissue regeneration. This paper reviews relevant scientific literature regarding basic science and brings real-world evidence regarding the use of orthobiologics in the treatment of chronic wounds, irrespective of aetiology. The discussion highlights the regenerative properties of PRP, PRF, BMA, BMAC and SVF, showcasing their potential to enhance wound healing. Despite advancements, further research is essential to elucidate the specific roles of each orthobiologic and determine optimal applications for different wound types. The conclusion underscores the evolving landscape in chronic wound management, with a call for more comprehensive studies to refine treatment strategies and maximize the benefits of regenerative medicine.

IntroductionBiliary tract cancer (BTC) is a lethal disease with a bad overall survivability, partly arising from inadequate therapeutic alternatives, detection at a belated stage, and a resistance to common therapeutic approaches. Ferroptosis is a form of programmed cell death that depends on reactive oxygen species (ROS) and iron, causing excessive peroxidation of polyunsaturated fatty acids (PUFAs). Therefore, the objective of this investigation is, whether ferroptosis can be induced in BTC in vitro and whether this induction is dependent on specific molecular markers.
MethodsThe study conducted resazurin assay and IC25/50 calculation to explore the possible cytotoxic outcomes of different classes of ferroptosis-inducing substances (FINs) on a comprehensive in vitro model of 11 BTC cell lines. Combinatory treatments with different cell death inhibitors were performed to evaluate the magnitude of ferroptosis induction. To ascertain whether ferroptotic cell death occurred, liperfluo and iron assay kits were employed to evaluate lipid ROS and intracellular iron abundance. Potential biomarkers of ferroptosis sensitivity were then assessed via western blot analysis, a rtPCR panel and functional assay kits.
ResultsThe study found that different FINs reduced cell viability in a cell line-dependent manner. In addition, we measured increased lipid ROS and intracellular Fe2+ levels upon exposure to FINs in BTC cells. Combining FINs with inhibitors of ferroptosis, necroptosis or apoptosis suggests the occurrence of ferroptotic events in BTC cell lines CCC-5, HuH-28 and KKU-055. Furthermore, we found that BTC cells display a heterogeneous profile regarding different molecular genes/markers of ferroptosis. Subsequent analysis revealed that sensitivity of BTC cells towards IKE and RSL3 positively correlated with CD71 and SLC7A11 protein expression.
ConclusionOur results demonstrate that induction of ferroptosis is a promising approach to inhibit BTC cell growth and that the sensitivity of BTC cells towards ferroptosis induction might be dependent on molecular markers such as CD71 and SLC7A11.
BioMD-Y is a comprehensive biobank study of children and adolescents with major depression (MD) and their healthy peers in Germany, collecting a host of both biological and psychosocial information from the participants and their parents with the aim of exploring genetic and environmental risk and protective factors for MD in children and adolescents.
Children and adolescents aged 8–18 years are recruited to either the clinical case group (MD, diagnosis of MD disorder) or the typically developing control group (absence of any psychiatric condition).
To date, four publications on both genetic and environmental risk and resilience factors (including FKBP5, glucocorticoid receptor activation, polygenic risk scores, psychosocial and sociodemographic risk and resilience factors) have been published based on the BioMD-Y sample.
Data collection is currently scheduled to continue into 2026. Research questions will be further addressed using available measures.

Research questionCan a strategy for scoring oocyte quality, based on cumulus cell (CC) gene expression, prioritize oocytes with the highest implantation potential, while limiting the number of embryos to be processed in culture and the number of supernumerary embryos to be vitrified?
DesignAn interventional, blinded, prospective cohort study was retrospectively analyzed. In the original study, patients underwent a fresh Day3 single embryo transfer with embryos ranked based on morphology and CC gene expression (Aurora Test). The additional ranking of the embryos with the Aurora Test resulted in significant higher clinical pregnancy and live birth rates. Now it is investigated if the Aurora Test ranking could be applied to select oocytes. The effect of an Aurora Test based restriction to 2 and 3 2PN or MII oocytes on clinical pregnancy and other outcomes, was analyzed in two subsets of patients with all 2PN (n = 83) or all MII oocytes (n = 45) ranked.
ResultsConsidering only the top three ranked 2PN oocytes, 95% of the patients would have received a fresh SET on Day3 resulting in 65% clinical pregnancies. This was not different from the pregnancy rate obtained in a strategy using all oocytes but significantly reduced the need for vitrification of supernumerary embryos by 3-fold. Considering only top-ranked MII oocytes gave similar results.
ConclusionsIn countries with legal restrictions on freezing of embryos, gene expression of CC can be used for the selective processing of oocytes and would thus decrease the twin pregnancy rate and workload, especially for embryo morphology scoring and transfers as the handling and processing of lower competence oocytes is prevented, while improving the ART outcome.

AimTo gather available scientific evidence on technologies used to teach hand hygiene to professional populations and lays involved in health care in the hospital setting. This systematic review was designed as proposed by Preferred Reporting Items for Systematic Reviews and Meta-Analysis, included studies reporting primary, original, quantitative research findings with no date limit and written in English, Spanish or Portuguese. The search was performed in the following electronic databases: Cochrane Library, Cumulative Index to Nursing and Allied Health Literature, Excerpta Medica dataBASE, Literatura Latino-Americana e do Caribe em Ciências da Saúde, US National Library of Medicine, Scopus, Web of Science, Google Scholar and ProQuest. The eligibility criteria were applied independently by two reviewers to select the studies, first by reading the titles and abstracts on the Rayyan platform and then by full text reading of the eligible studies. After a descriptive analysis, the studies were subjected to critical evaluation of their methodological quality using JBI tools.
ResultsSeven studies were included, addressing various methods for teaching hand hygiene using different technological resources, such as audiovisual electronic devices, videos, virtual reality, and gamification using tablets and smartphones, in different populations.
ConclusionUsing technologies to teach hand hygiene considerably helps patients, visitors, and relatives in learning the procedures and efficiently improves hand hygiene compliance rates among healthcare professionals, creating evidence-based repetitive learning opportunities for patients and caregivers.
This study aims to assess risk factors for SARS-CoV-2 infection by combined design; first comparing positive cases to negative controls as determined by PCR testing and then comparing these two groups to an additional prepandemic population control group.
Test-negative design (TND), multicentre case–control study with additional population controls in South-Eastern Norway.
Adults who underwent SARS-CoV-2 PCR testing between February and December 2020. PCR-positive cases, PCR-negative controls and additional age-matched population controls.
The associations between various risk factors based on self- reported questionnaire and SARS-CoV-2 infection comparing PCR-positive cases and PCR-negative controls. Using subgroup analysis, the risk factors for both PCR-positive and PCR-negative participants were compared with a population control group.
In total, 400 PCR-positive cases, 719 PCR-negative controls and 14 509 population controls were included. Male sex was associated with the risk of SARS-CoV-2 infection only in the TND study (OR 1.9, 95% CI 1.4 to 2.6), but not when PCR-positive cases were compared with population controls (OR 1.2, 95% CI 0.9. to 1.5). Some factors were positively (asthma, wood heating) or negatively (hypertension) associated with SARS-CoV-2 infection when PCR-positive cases were compared with population controls, but lacked convincing association in the TND study. Smoking was negatively associated with the risk of SARS-CoV-2 infection in both analyses (OR 0.5, 95% CI 0.3 to 0.8 and OR 0.6, 95% CI 0.4 to 0.8).
Male sex was a possible risk factor for SARS-CoV-2 infection only in the TND study, whereas smoking was negatively associated with SARS-CoV-2 infection in both the TND study and when using population controls. Several factors were associated with SARS-CoV-2 infection when PCR-positive cases were compared with population controls, but not in the TND study, highlighting the strength of combining case–control study designs during the pandemic.
To explore how parents experienced their child with delirium and how parents viewed our delirium management bundle.
We conducted a qualitative exploratory descriptive study using semi-structured individual or dyad interviews.
Twelve semi-structured interviews with 16 parents of 12 critically ill children diagnosed with delirium in a paediatric intensive care unit were conducted from October 2022 to January 2023 and analysed through a reflexive thematic analysis.
We generated five themes: (1) knowing that something is very wrong, (2) observing manifest changes in the child, (3) experiencing fear of long-term consequences, (4) adding insight to the bundle, and (5) family engagement.
The parents in our study were able to observe subtle and manifest changes in their child with delirium. This caused fear of lasting impact. The parents regarded most of the interventions in the delirium management bundle as relevant but needed individualization in the application. The parents requested more information regarding delirium and a higher level of parent engagement in the care of their child during delirium.
This paper contributes to understanding how parents might experience delirium in their critically ill child, how our delirium management bundle was received by the parents, and their suggestions for improvement. Our study deals with critically ill children with delirium, their parents, and staff working to prevent and manage paediatric delirium (PD) in the paediatric intensive care unit.
The consolidated criteria for reporting qualitative research guidelines were used to ensure the transparency of our reporting.
No patient or public contribution to the research design.
- It increases awareness of the parent's perspective on PD in critically ill children. - It shows how PD might affect parents, causing negative emotions such as distress, frustration, and fear of permanent damage. - It shows that the parents in our study, in addition to the care bundle, requested more information on delirium and more involvement in the care of their delirious child.
Gynaecological cancer illness and treatment have a significant impact on women's sexual health and concerns regarding sexual health are known to be an unmet need in survivors. The digital support programme Gynea was designed to enhance women's health, including sexual health, after gynaecological cancer treatment. This study aimed to explore how cancer survivors experienced participation in Gynea.
This is a phenomenological hermeneutic study. Individual, in-depth semi-structured interviews were conducted to explore lived experiences. Twenty women were interviewed after completing the Gynea programme. The transcripts were analysed using Lindseth and Norberg's phenomenological hermeneutic method.
Three main themes (with subthemes) emerged from the analysis: (1) A silent existential trauma; (2) Redefining sexual health; (3) Communicating with a partner about sexuality. The women redefined sexual health rather than just being sexual intercourse, being a rediscovery of the body. The women's increased awareness and understanding of their own sexual health empowered their communication about their sexuality with their partners. This was important for regaining sexual health and intimacy in their relationships.
Participation in Gynea helped to strengthen the women's sexual integrity. Knowledge and support empowered them to take care of their sexual needs and communicate these with their partners.
Healthcare services and nurses need to be aware that sexual health is an existential state of being, in which good sexual health does not necessarily equate to sexual function, but rather to sexual empowerment. Digital support with nurse guidance can support women in caring for their sexual health after cancer illness by thematizing sexual health with a holistic approach and should be part of the medical treatment.
Twenty gynaecological cancer survivors contributed by sharing their experiences from the sexual health module in Gynea.
US hospitals are focussing more than ever on meeting important patient social needs. Patients often make multiple trips to hospitals related to nonmedical issues that could likely be averted through the increased integration of case management strategies. Although the percentage of hospitals using advanced practice nurses (APNs) in this role is still relatively low, we explore the idea that employing APN case managers improves hospitals' abilities to alleviate hospital overusage.
The study used a cross-sectional design.
We used the 2021 American Hospital Association data set, which includes 5855 hospitals, of which 4315 were general medical hospitals.
Using descriptive statistics and Poisson regression, we discovered that employing APN case managers in US acute care hospitals is associated with an increased likelihood that hospitals will implement strategies addressing patient social needs.
When hospitals screen patients for social needs and formulate and implement internal and external strategies designed to meet patient social needs, many stakeholders stand to benefit. Should more hospitals observe such benefits when utilizing an APN case manager model, it will likely proliferate, and demand for APNs could accelerate further.
Following the reduction in unnecessary patient visits and readmissions, hospitals' scarce resources are freed up to offer timely care to patients that are truly medically in need. Furthermore, financial performance improves under this scenario. APNs play a critical role in enabling hospitals to realize such benefits.
No patient or public contribution. We used archival data in this study.
Existing literature suggests that transgender women (TW) may be at high risk for adverse mental health due to stress attributed to combined experiences of stigma and complex social and structural vulnerabilities. Little research has examined how these co-occurring experiences relate to mental health. We aimed to test a theoretically driven conceptual model of relationships between stigma, social and structural vulnerabilities, and mental health to inform future intervention tailoring.
Partial least square path modeling followed by response-based unit segmentation was used to identify homogenous clusters in a diverse community sample of United States (US)-based TW (N = 1418; 46.2% White non-Hispanic). This approach examined associations between latent constructs of stigma (polyvictimization and discrimination), social and structural vulnerabilities (housing and food insecurity, unemployment, sex work, social support, and substance use), and mental health (post-traumatic stress and psychological distress).
The final conceptual model defined the structural relationship between the variables of interest within stigma, vulnerability, and mental health. Six clusters were identified within this structural framework which suggests that racism, ethnicism, and geography may be related to mental health inequities among TW.
Our findings around the impact of racism, ethnicism, and geography reflect the existing literature, which unfortunately shows us that little change has occurred in the last decade for TW of color in the Southern US; however, the strength of our evidence (related to sampling structure and sample size) and type of analyses (accounting for co-occurring predictors of health, i.e., stigma and complex vulnerabilities, reflecting that of real-world patients) is a novel and necessary addition to the literature. Findings suggest that health interventions designed to offset the negative effects of stigma must include anti-racist approaches with components to reduce or eliminate barriers to resources that contribute to social and structural vulnerabilities among TW. Herein we provide detailed recommendations to guide primary, secondary, and tertiary prevention efforts.
This study demonstrated the importance of considering stigma and complex social and structural vulnerabilities during clinical care and design of mental health interventions for transgender women who are experiencing post-traumatic stress disorder and psychological distress. Specifically, interventions should take an anti-racist approach and would benefit from incorporating social support-building activities.
