Ross","doi":"10.3389/fmed.2024.1411013","DOIUrl":"https://doi.org/10.3389/fmed.2024.1411013","url":null,"abstract":"This paper addresses the dilemmas of accessibility, comprehensiveness, and ownership related to health data. To resolve these dilemmas, we propose and justify a novel, globally scalable reference architecture for a Personal Health Data Space (PHDS). This architecture leverages decentralized content-addressable storage (DCAS) networks, ensuring that the data subject retains complete control and ownership of their personal health data. In today's globalized world, where people are increasingly mobile for work and leisure, healthcare is transitioning from episodic symptom-based treatment toward continuity of care. The main aims of this are patient engagement, illness prevention, and active and healthy longevity. This shift, along with the secondary use of health data for societal benefit, has intensified the challenges associated with health data accessibility, comprehensiveness, and ownership.The study is structured around four health data use case scenarios from the Estonian National Health Information System (EHIS): primary medical use, medical emergency use, secondary use, and personal use. We analyze these use cases from the perspectives of accessibility, comprehensiveness, and ownership. Additionally, we examine the security, privacy, and interoperability aspects of health data.The proposed architectural solution allows individuals to consolidate all their health data into a unified Personal Health Record (PHR). This data can come from various healthcare institutions, mobile applications, medical devices for home use, and personal health notes.The comprehensive PHR can then be shared with healthcare providers in a semantically interoperable manner, regardless of their location or the information systems they use. Furthermore, individuals maintain the autonomy to share, sell, or donate their anonymous or pseudonymous health data for secondary use with different systems worldwide. The proposed reference architecture aligns with the principles of the European Health Data Space (EHDS) initiative, enhancing health data management by providing a secure, cost-effective, and sustainable solution.","PeriodicalId":502302,"journal":{"name":"Frontiers in Medicine","volume":"48 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-07-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141643758","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Additionally, our hybrid pre-processing strategy aims to streamline the learning process by offering model-focused input. We evaluated our model's effectiveness on the publicly available AREDS dataset by using standard metrics such as image-level and parameter-level analyzes. Linear regression analysis reveals an average Pearson correlation coefficient (R) of 0.9876 across all quadratic transformation parameters. Image-level evaluation, comprising qualitative and quantitative analyzes, showcases significant improvements in Structural Similarity Index (SSIM) and Normalized Cross Correlation (NCC) scores, indicating its robust performance. Notably, precise matching of the optic disc and vessel locations with minimal global distortion are observed. These findings underscore the potential of GPT-based approaches in image registration methodologies, promising advancements in diagnosis, treatment planning, and disease monitoring in ophthalmology and beyond.","PeriodicalId":502302,"journal":{"name":"Frontiers in Medicine","volume":"20 5","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-07-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141644199","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A diverse array of algorithms has emerged to facilitate the automated diagnosis of numerous medical and surgical retinal conditions. The development of these algorithms necessitates extensive training using large datasets of retinal images. This approach has demonstrated a promising impact, especially in increasing accuracy of diagnosis for unspecialized clinicians for various diseases and in the area of telemedicine, where access to ophthalmological care is restricted. In parallel, robotic technology has made significant inroads into the medical field, including ophthalmology. The vast majority of research in the field of robotic surgery has been focused on anterior segment and vitreoretinal surgery. These systems offer potential improvements in accuracy and address issues such as hand tremors. However, widespread adoption faces hurdles, including the substantial costs associated with these systems and the steep learning curve for surgeons. These challenges currently constrain the broader implementation of robotic surgical systems in ophthalmology.

Assessing the characteristics and risk factors of severe AD is central to healthcare workers’ understanding and subsequent education of patients for the most optimal outcomes. The clinical characteristics are known to vary depending on populations and regions. AD has been well-documented in the global North in mainly Caucasian populations, while very few studies have been conducted on African patients residing in Africa. This study assessed the clinical characteristics, severity, and sociodemographic factors of children with AD in Southern Ethiopia.A hospital-based cross-sectional study was conducted among 461 children and their caregivers in four randomly selected hospitals in Southern Ethiopia from October 2022 to September 2023. A systematic sampling technique was used to enroll study participants. Clinical profile and sociodemographic data were collected by trained data collectors. The Scoring Atopic Dermatitis (SCORAD) index tool was used. The descriptive analysis was performed to characterize study participants. Univariate and ordinary logistic regression were used to identify factors associated with the SCORAD index score. The OR with 95% was used to show the strength of association, and a p-value of <0.05 was used to declare the level of significance.Out of 461 AD-diagnosed children, 212 (46%) were girls and 249 (54%) were boys. In the sample of pediatric patients, 149 (32.3%) exhibited mild AD, 231 (46.2%) presented with moderate, and 99 (21.5%) showed signs and symptoms of severe AD. All patients had itching. Dryness of skin, excoriation, and erythema, followed by lichenification, were the most observed signs. In the ordinary logistic regression model, age onset of the disease [AOR 95% CI 1.95 (1.3–2.94)], sex of caregiver or family [AOR 95% CI 0.61 (0.41–0.90)], family atopy history [AOR 95% CI 0.64 (0.44–0.93)], mother education status [95% CI 2.45 (1.1–5.47)], and use of herbal medication [AOR 95% CI 0.50 (0.33–0.79)] were significantly associated with the severity of AD.In this study, 68% of children were found to have moderate-to-severe AD. Early onset, maternal education, familial atopy history, sex of caregiver, and use of herbal medication were independent predictors of severe AD in children. We recommend further investigation into these variables for their potential to serve as markers to assess the severity of AD and improve the care and management of children with AD in Ethiopia.","PeriodicalId":502302,"journal":{"name":"Frontiers in Medicine","volume":"25 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-07-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141647756","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Three reviewers independently screened the abstracts of the selected studies and extracted data from full-text articles. The data were subsequently tabulated and compared for consistency. The bias associated with each included study was evaluated according to the OSQE method.Forty-seven studies meet definitive inclusion criteria. The quality of the observations was considered low in 26 of the included studies and moderate in 21 of the included studies. In comparative screening studies, the pooled prevalence of multiple HR-HPV was 39.1% (95% CI = 33.7–44.7) among women with (n = 1734) and 21.6% (95% CI = 17.3–26.1) in those without HIV infection (n = 912) (OR = 2.33, 95% CI = 1.83–2.97, I2 = 2.8%).

Among women with HIV, the risk of HSIL diagnosed either by cytology or histology was higher among those with overall (OR = 2.62, 95% CI = 1.62–4.23) and HR multiple infections than those with single HPV infection (OR = 1.93, 95% CI = 1.51–2.46). Among women with HIV, the excess rates of multiple HPV infections and the excess risk of associated HSIL were consistent across studies including both HIV-naïve subjects and those on antiretroviral therapy, as well as in studies with different rates of immunocompromised women. When study quality (low vs. moderate) was used as a moderator, the results were unchanged.Multiple HR-HPV infections are common among women living with HIV and are associated with an increased prevalence of HSIL.

In response to this emerging need, the Eastern Mediterranean Public Health Network (EMPHNET) adapted its Public Health Empowerment Program-Basic Field Epidemiology (PHEP-BFE) to a Blended Learning Model. This study evaluates the Blended PHEP-BFE program in Iraq, Egypt, and Lebanon, focusing on participant reactions and learning outcomes.A descriptive evaluation was conducted, aligned with the first two levels of Kirkpatrick's model. Online questionnaires were administered to participants and facilitators through EMPHNET's Learning Management System (LMS). Qualitative and quantitative data were analyzed to assess program effectiveness, satisfaction, and challenges.A total of 138 PHEP-BFE participants (119 (86.2%) males and 19 (13.8%) females) from Iraq (n = 61), Egypt (n = 66), and Lebanon (n = 11) responded to the questionnaire. The majority of the participants (96.4%) reported that they were satisfied with PHEP-BFE. Notably, 77.5% of participants rated the blended learning program as very good or excellent, 18.1% rated it good, and 3.6% found it average, with a minimal 0.7% expressing dissatisfaction. The majority of participants agreed that the blended PHEP-BFE enhanced their capacity to conduct, review and monitor surveillance data (95.7%), perform descriptive data analysis (94.2%), effectively communicate information with agency staff and the local community (95.7%), write summaries of surveillance findings or outbreak investigations (95.7%), use MS Excel to enter, analyze, and display public health surveillance data (91.3%), prepare and administer an oral presentation for fieldwork (94.9%), and increase their knowledge of fundamental field epidemiology (94.9%). The participants responded positively to the program's content, training duration, learning platform, facilitators and mentors, and fieldwork.The study showcases the success of the blended PHEP-BFE in diverse contexts, emphasizing positive participant reactions and improved competencies.

We evaluated the prognostic and predictive value of 15 biomarkers, including the glucose-albumin ratio, in elderly patients with hip fractures. The primary outcome measure was the incidence of postoperative UTIs.The glucose to albumin ratio transformed into GAR was superior to any other biomarker in predicting postoperative UTIs in elderly hip fracture patients (AUC = 0.756, p < 0.001). Elevated GAR (using the best cut-off value of 0.18) was independently associated with postoperative UTIs (OR 3.20, 95% CI 2.23–4.58).
