Wood-derived cellulose materials obtained by structure-retaining delignification are attracting increasing attention due to their excellent mechanical properties and great potential to serve as renewable and CO2 storing cellulose scaffolds for advanced hybrid materials with embedded functionality. Various delignification protocols and a multitude of further processing steps including polymer impregnation and densification are applied resulting in a large range of properties. However, treatment optimization requires a more comprehensive characterization of the developed materials in terms of structure, chemical composition, and mechanical properties for faster progress in the field. Herein, the current protocols for structure-retaining delignification are reviewed and the emphasis is placed on the mechanical characterization at different hierarchical levels of the cellulose scaffolds by experiments and modeling to reveal the underlying structure-property relationships.This is a cross-sectional study whose objective was to identify clustering of lifestyle behaviors among undergraduate nursing students to inform health promotion efforts and improve health outcomes later in life. DIRECT RED 80 compound library chemical All 353 undergraduate nursing students from the School of Nursing in a public university, Bahia, Brazil were invited to participate. The inclusion and exclusion criteria were according to the major project. Participants must be enrolled and attending the 1st to 10th semester, with a minimum age of 18 years. Participants were excluded if they had any physical disabilities that limited the collection of anthropometric measures or were completing an internship off-campus. A total of 286 undergraduate nursing students met the criteria and completed the survey. The questionnaires included standardized measures for demographic, academic, and lifestyle behaviors (e.g., tobacco use, alcohol use, physical activity level, sedentary behavior, and fruits and vegetables consumed). Latent class analysis was performed to identify any clustering of lifestyle behaviors. Descriptive analyses indicated that 3.1% of the students were smokers, 23.1% consumed alcohol, 34.3% were inactive, 85.0% were sedentary, and 80.8% did not consume recommended amounts of fruits and vegetables. Latent class analysis produced four distinct subtypes of health risk (a) low-health risk (33.57%); (b) moderate-health risk (27.97%); (c) high-health risk (19.58%); and (d) very high-health risk (18.88%). Approximately 38.5% of students were in the very high or high-risk classes. The proportion of students with very high and high-health risks emphasizes the importance of health promotion programs for university nursing students.

Quality improvement (QI) is increasingly featuring in the United Kingdom (UK) National Health Service (NHS) agenda to promote safety, effectiveness and patient experience. However, the use of QI techniques by healthcare professionals appears limited and constrained with only isolated examples of good practice. This study explores QI within the pharmacy context. Focusing on the community pharmacy 'Healthy Living Pharmacy scheme', this study aims to explore changes in QI understanding resulting from a postgraduate QI educational intervention.

Four focus groups were held involving 13 community pharmacists enrolled onto a newly developed postgraduate QI educational module. Two focus groups were held before and two after the module's completion. Knowledge of QI and practical applications following the learning was explored.

Three themes emerged pharmacists' motivation for learning about QI, conceptual understanding and translation into practice. Pharmacists expressed positive views about learning new skills dge, organisational culture and application in practice.

We sought to determine the time course of clinical and histologic differences between aspirated inorganic and organic foreign bodies.

In-vivo.

Twenty Sinclair miniature swine (Sus scrofa domesticus) were divided into two groups-inorganic or organic foreign bodies. Either an organic (peanut) or an inorganic (Lego) foreign body was placed within a bronchus and left for 3, 5, 7, 14 or 21 days. The airway was reassessed at the predetermined endpoint at which time endoscopic, gross, and histopathological findings were documented. Specimens were scored with a pathologic scoring system to assess injury severity from the foreign body.

Foreign bodies were successfully placed in all 20 swine. Two animals required early euthanasia due to respiratory compromise. The foreign body was identified grossly in eight (40%) animals. An additional three (15%) had microscopic evidence suggestive of a previous foreign body of an undetermined duration. There was no difference in injury severity between organic and inorganic foreign bodies. The 3-day group had injuries limited to the bronchial lining, whereas the longer duration groups had bronchial and adjacent lung parenchymal involvement. There was no difference in injury severity between days 5 and 21.

Airway foreign bodies initially cause bronchial damage. After 5 days, the foreign body causes lung parenchymal changes. There was no difference in airway lesion severity between organic and inorganic foreign bodies.

Understanding how yoga works is essential to optimizing interventions. The present study tested five potential psychosocial mechanisms (increased mindfulness, interoceptive awareness, spiritual well-being, self-compassion and self-control) that have been proposed to explain yoga's impact on stress. Forty-two participants (62% female; 64% White) in a yoga program for stress reduction completed surveys at baseline (T1), mid-intervention (T2) and post-intervention (12 weeks; T3). We measured two aspects of stress, perceived stress and stress reactivity. Changes were assessed with paired t-tests; associations between changes in mechanisms were tested in residual change models. Only stress reactivity decreased, on average, from T1 to T3. Except for self-compassion, all psychosocial mechanisms increased from T1 to T3, with minimal changes from T2 to T3. Except for self-control, increases in each mechanism were strongly associated with decreases in both measures of stress between T1 and T2 and decreases in perceived stress from T1 to T3 (all p's less then 0.
