Background: Spring-assisted surgery (SAS) and cranial vault remodeling (CVR) are widely used surgical techniques to correct sagittal craniosynostosis (SC). The authors evaluated changes in regional morphology of patients with SC who had undergone SAS or CVR, using the frontal bossing index (FBI), occipital bulleting index, vertex narrowing index (VNI), and scaphocephalic severity index (SCI) to capture differences in anterior protrusion, posterior protrusion, width restriction, and global dysmorphology, respectively.

Methods: Indices were measured on computed tomography and 3-dimensional photographs (n = 788) of 257 patients with SC from 2001 through 2022 who underwent SAS (n = 177) or CVR (n = 80).

Anaesthesia is sometimes required for the effective restraint of laboratory pigs for sample collection. Yet, anaesthesia can initiate a range of physiological disruptions that can increase variability in study data and lead to poorer animal welfare. Judicious use of anaesthesia can mitigate experimental, human safety, and animal welfare concerns, but it does not eliminate the potential for adverse effects.

Although perceptions and uses vary, nature-based health interventions (NBHIs) help facilitate the additional health benefits of physical activity (PA) experienced in nature, thereby reducing all-cause morbidity and mortality. The purpose of this mixed-methods, cross-sectional study was to better understand perceptions, terminology, and participation in NBHIs. A questionnaire was developed by reviewing validated instruments and gauging expert experience with stakeholders.

This study examines the intersectional role of citizenship and gender with career self-efficacy amongst 10,803 doctoral and postdoctoral trainees in US universities. These biomedical trainees completed surveys administered by 17 US institutions that participated in the National Institutes of Health Broadening Experiences in Scientific Training (NIH BEST) Programs. Findings indicate that career self-efficacy of non-citizen trainees is significantly lower than that of US citizen trainees.

Late presentations of liver failure were previously rare in clinical practice given the high mortality of sickle cell disease (SCD) and shorter life expectancy compared to the general population. With advancements in therapeutics for SCD, patients with SCD have increased lifespans, and with them, patients are placed at increased risk for differing patterns of chronic and end-organ failures. We describe a case of an elderly patient who had multiple chronic complications from her years of SCD, including end-stage renal disease (ESRD) on hemodialysis, acquired hemochromatosis, cirrhosis, and pulmonary hypertension.
