ObjectiveRats are born with morphologically immature lungs, but intact surfactant system. The aim of this study was to characterize the surfactant producing alveolar epithelial cells type II (AEII) during alveolarization and find relationships between the intracellular surfactant pool and alveolar surface area, lung volume and body weight.
MethodsAfter exsanguination, lungs of 3, 7, 14, 21 and 90 days old rats were inflated with a pressure of 10 mm H20 and fixed by perfusion and prepared for light and electron microscopy. Using different stereological parameters AEII were characterized.
ResultsAt day 21, the end of bulk alveolarization, the alveolar surface and the number of AEII increased significantly but their volume and size did not change compared to values before alveolarization. The number of AEII, but not the AEII volume correlated significantly with alveolar surface and lung volume. The size and volume weighted mean volume of lamellar bodies (Lb) as well as the Lb volume per AEII did not change during alveolarization. Total Lb volume was significantly higher at the end of bulk alveolarization compared to values before alveolarization.
ConclusionThe adaptation of the intracellular surfactant during postnatal development occurred predominantly by increasing the number of AEII.
To describe telephone-triage nurses' perceptions of their well-being and the system factors that influenced their well-being while conducting telephone-triage for COVID-19 during the pandemic.
This descriptive, qualitative study applied both inductive and deductive analysis to generate themes.
We interviewed a convenience sample of 27 nurses from two health systems about their perceptions of well-being when triaging patient calls about COVID-19 and reasons for those perceptions. Data collection occurred between November 2020 and June 2021. Themes were organised using the National Academies of Science, Engineering and Medicine framework.
Telephone-triage nurses' well-being was significantly impacted by COVID-19. Uncertainty regarding evolving COVID-19 guidance, increased call volumes and difficult patient responses were some of the key work system challenges that impacted nurses' well-being.
Our findings suggest the need to revisit work system factors that impact the well-being of telephone-triage nurses and develop organisational interventions to support nurses to provide optimal care during crisis situations.
Organisational information infrastructure should be bolstered for future pandemic responses to minimise impacts on nurses' well-being. Additionally, leaders need to realign tasks, workflows and workload of telephone triage during pandemic surges to prevent excessive demands on nurses.
This work contributes to understanding telephone-triage nurses' well-being during COVID-19. The increased demands they faced and impact on their well-being point to opportunities for organisational well-being interventions and development of crisis standards for tele-triaging to support nurses during high-stress, crisis situations.

Distal radius fractures account for one-fifth of all fractures in the active elderly population and may cause chronic pain, loss of hand function and reduced work productivity, imposing a significant socioeconomic burden. Most are initially treated with closed reduction and casting, but 30% subsequently require surgery due to insufficient realignment. The current approaches for analgesia for closed reduction are suboptimal. A brachial plexus nerve block provides complete pain relief and muscle relaxation distal to the elbow, potentially creating better conditions for realignment of the fractured bone ends. This may ultimately translate into reduced need for surgery and result in better functional outcomes and fewer complications compared to a haematoma block, which is the current standard care in Denmark.
The BLOCK Trial is an investigator-initiated, parallel-group, allocation-concealed, outcome assessor and analyst-blinded, superiority, randomised, controlled, clinical multicentre trial performed at 11 Danish emergency departments. Eligible adult patients with a distal radius fracture who need closed reduction will be included and allocated 1:1 to either an ultrasound-guided brachial plexus nerve block or a haematoma block. The primary outcome is the proportion of patients with distal radius fracture surgery 90 days after closed reduction. We will include 1716 participants to detect or discard a relative risk reduction of surgery of 20%. Secondary outcomes include treatment-related complications, patient-reported wrist function, pain during closed reduction and proportion of patients with unacceptable radiographic fracture position immediately after closed reduction.
The trial is approved by the Danish Medicines Agency and the Danish Research Ethics Committees (EU CT number: 2024-512191-35-00). All results will be summarised on www.theblocktrial.com, clinicaltrials.gov and euclinicaltrials.eu after publication. Primary and secondary outcome results from 0 to 90 days will be presented in the main article and submitted to a peer-reviewed journal. Results from outcomes on the 12-month follow-up will be presented separately.
To explore how patients with Inflammatory bowel disease experienced encounters with healthcare professionals in two gastrointestinal outpatient clinics to demonstrate what matters in the communication between patients and healthcare professionals.
This fieldwork study is part of a larger study developing an application for patients with inflammatory bowel disease in a framework inspired by Participatory Design. Participatory design consists of three phases and this study focused on the first phase, needs assessment. A phenomenological hermeneutic approach and qualitative methods were applied to obtain an understanding of patients' needs.
Three weeks of participant observations and three focus groups with 14 subjects were conducted at two university hospitals in Denmark. Field notes and interview transcripts were analysed using condensation of meaning and interpreted based on interactional nursing practice theory. The reporting method adhered to the EQUATOR guideline: COREQ.
Four themes emerged: Easy and dependable access to healthcare professionals. Predictability of follow-up appointments. Importance of privacy during patient exams and Quality of time spent with healthcare professionals.
Easy, dependable access, privacy, presence and predictability of follow-up appointments were important to patients with Inflammatory Bowel Disease.
In communication with patients with inflammatory bowel disease, healthcare professionals must be aware of privacy and the importance of predictable follow-up agreements. They must be aware that presence and easy, reliable access positively affect patients' self-care skills.
This study is part of a larger project based on Participatory design involving patients and healthcare professionals in the development of technology to support communication.
