Investigations are sometimes required to verify dose assessments or, where the reliability of the original results is known to be in question, to replace them with an estimate of the dose. In Finland, such investigations are conducted by three different parties: the Radiation and Nuclear Safety Authority (STUK), the individual monitoring service (IMS) and the parties operating a radiation practice (the undertakings). The reasons for such investigations as well as the findings from them vary widely between different parties. To determine their usefulness, all investigations carried out on Finnish radiation workers by the STUK, the IMS and the undertakings during 2004-13 have been reviewed. This paper presents the number, reasons for and findings of these investigations. The effect of the investigations on the recorded individual doses as well as on the working methods and other aspects of radiation protection in the work environment are described.

The parental care-seeking behavior of children with osteogenesis imperfecta based on the Anderson's model: a qualitative study.
BMC Nurs
January 2025
Department of Orthopedic, National Clinical Research Center for Child Health and Disorders, Ministry of Education Key Laboratory of Child Development and Disorders, Children's Hospital of Chongqing Medical University, Chongqing, China.
Objective: This study aims to analyze the medical-seeking behavior of Osteogenesis Imperfecta(OI) children in Southwest China, summarize and analyze the issues in their medical process, and propose corresponding improvement strategies.
Methods: A phenomenological study involving semi-structured interviews with 20 OI caregivers at a tertiary centre for children from March to August 2021 was analyzed thematically, following Anderson's model.
Results: We identified eight themes in the data: 1)Regional disparities of OI management, 2)Big economic burden, 3)High-risk population, 4)Lack of health education, 5)Multiple treatments,6)Strict treatment indications,7)Disappointing therapeutic outcomes,8)Effective or ineffective treatment results.
TAD-SIE: sample size estimation for clinical randomized controlled trials using a Trend-Adaptive Design with a Synthetic-Intervention-Based Estimator.

Department of Electrical and Computer Engineering, Princeton University, Princeton, 08544, NJ, USA.
Background: Phase-3 clinical trials provide the highest level of evidence on drug safety and effectiveness needed for market approval by implementing large randomized controlled trials (RCTs). However, 30-40% of these trials fail mainly because such studies have inadequate sample sizes, stemming from the inability to obtain accurate initial estimates of average treatment effect parameters.
Methods: To remove this obstacle from the drug development cycle, we present a new algorithm called Trend-Adaptive Design with a Synthetic-Intervention-Based Estimator (TAD-SIE) that powers a parallel-group trial, a standard RCT design, by leveraging a state-of-the-art hypothesis testing strategy and a novel trend-adaptive design (TAD).
Understanding retinal tau pathology through functional 2D and 3D iPSC-derived in vitro retinal models.
Acta Neuropathol Commun
January 2025
Department of Physiology and Pharmacology, Sapienza University of Rome, 00185, Rome, Italy.
The generation of retinal models from human induced pluripotent stem cells holds significant potential for advancing our understanding of retinal development, neurodegeneration, and the in vitro modeling of neurodegenerative disorders. The retina, as an accessible part of the central nervous system, offers a unique window into these processes, making it invaluable for both study and early diagnosis. This study investigates the impact of the Frontotemporal Dementia-linked IVS 10 + 16 MAPT mutation on retinal development and function using 2D and 3D retinal models derived from human induced pluripotent stem cells.

Department of Midwifery, Nursing and Midwifery Faculty, Bushehr University of Medical Sciences, Bushehr, Iran.
Introduction: Despite the existing reports on mistreatment and disrespectful maternal care, few studies have investigated interventions to mitigate this issue. The present study aims to assess the impact of consulting midwives on maternal rights charter on perception of respectful maternity care and postpartum blues among postpartum women in two hospitals in southern Iran.
Methodology: This quasi-experimental study was conducted on 437 postpartum women (217 mothers before the intervention and 220 mothers after the intervention) and 44 midwives working in the maternity ward of two hospitals affiliated to Bushehr University of Medical Sciences in 2023-2024.
Lesbian, gay, bisexual, and transgender clinical competence of health professionals in Poland and Spain: results of the health exclusion research in Europe (HERE) study.

Group of Research in Care and Health (GRUPAC), Faculty of Health Sciences, University of La Rioja, Logroño, 26006, Spain.
Introduction: Health disparities experienced by lesbian, gay, bisexual, and transgender (LGBT) individuals have been partially attributed to healthcare professionals' lack of cultural competence in addressing their specific needs. This study aimed to assess the differences in competencies and preparedness among health professionals from Poland and Spain when working with LGBT patients.
Methodology: Data were collected between June and August 2024 through a cross-sectional survey involving 673 health professionals (Mage = 33.
