Fowler's Sneaker Depth (FSD), analogous to the well known Secchi disk depth (Zsd), is a visually discerned citizen scientist metric used to assess water clarity in the Patuxent River estuary. In this study, a simple remote sensing algorithm was developed to derive FSD from space-borne spectroradiometric imagery. An empirical model was formed that estimates FSD from red-end remote sensing reflectances at 645 nm, Rrs(645). The model is based on a hyperbolic function relating water clarity to Rrs(645) that was established using radiative transfer modeling and fine tuned using in-water FSD measurements and coincident Rrs(645) data observed by NASA's Moderate Resolution Imaging Spectroradiometer aboard the Aqua spacecraft (MODISA)...

Class B G-protein-coupled receptors are major targets for the treatment of chronic diseases, such as osteoporosis, diabetes and obesity. Here we report the structure of a full-length class B receptor, the calcitonin receptor, in complex with peptide ligand and heterotrimeric Gαsβγ protein determined by Volta phase-plate single-particle cryo-electron microscopy. The peptide agonist engages the receptor by binding to an extended hydrophobic pocket facilitated by the large outward movement of the extracellular ends of transmembrane helices 6 and 7...

This paper investigates the health effects of the introduction of a near universal paid parental leave (PPL) scheme in Australia, representing a natural social policy experiment. Along with gender equity and workforce engagement, a goal of the scheme (18 weeks leave at the minimum wage rate) was to enhance the health and wellbeing of mothers and babies. Although there is evidence that leave, especially paid leave, can benefit mothers' health post-partum, the potential health benefits of implementing a nationwide scheme have rarely been investigated...

The quality of care delivered by orthopedic surgeons continues to grow in importance. Multiple orthopedic programs, organizations, and committees have been created to measure the quality of surgical care and reduce the incidence of medical adverse events. Structured root cause analysis and actions (RCA2) has become an area of interest. If performed thoroughly, RCA2 has been shown to reduce surgical errors across many subspecialties. The Accreditation Council for Graduate Medical Education has a new mandate for programs to involve residents in quality improvement processes...

Patients with rheumatoid arthritis are at increased risk for cardiovascular disease. The prerequisites for reducing the risk of cardiovascular disease are adequate levels of knowledge and being aware of the risk. In this study, the levels of knowledge about cardiovascular disease among patients with rheumatoid arthritis and the perception were evaluated in relation to their actual 10-year risk of cardiovascular disease. This cross-sectional study of 200 patients with rheumatoid arthritis was conducted in a university-affiliated hospital in South Korea...

Type 1 diabetes and thyroid disease are T cell-dependent autoimmune endocrinopathies. The standard substitutive administration of the deficient hormones does not halt the autoimmune process; therefore, development of immunotherapies aiming to preserve the residual hormonal cells, is of crucial importance. PTPN22 C1858T mutation encoding for the R620W lymphoid tyrosine phosphatase variant, plays a potential pathophysiological role in autoimmunity. The PTPN22 encoded protein Lyp is a negative regulator of T cell antigen receptor signaling; R620W variant, leading to a gain of function with paradoxical reduced T cell activation, may represent a valid therapeutic target...

Emerging evidence indicates that repetitive head impacts, even at a sub-concussive level, may result in exacerbated or prolonged neurologic deficits in athletes. This study aimed to: 1) quantify the effect of repetitive head impacts on the alteration of neuronal activity based on fMRI of working memory after a high school football season; and 2) determine whether a neck collar that applies mild jugular vein compression to reduce brain energy absorption in head impact through slosh mitigation can ameliorate the altered fMRI activation during a working memory task...

Outcome after severe traumatic brain injury (TBI) differs substantially between hospitals. Explaining this variation begins with understanding the differences in structures and processes of care, particularly at intensive care units (ICUs) where acute TBI care takes place. We invited trauma medical directors (TMDs) from 187 centers participating in the American College of Surgeons Trauma Quality Improvement Program to complete a survey. The survey domains included ICU model, type, availability of specialized units, staff, training programs, standard protocols and order sets, approach to withdrawal of life support, and perceived level of neurosurgeons' engagement in the ICU management of TBI...

This study presents a novel metal-organic-framework-engaged synthesis route based on porous tellurium nanotubes as a sacrificial template for hierarchically porous 1D carbon nanotubes. Furthermore, an ultrathin Fe-ion-containing polydopamine layer has been introduced to generate highly effective FeNx C active sites into the carbon framework and to induce a high degree of graphitization. The synergistic effects between the hierarchically porous 1D carbon structure and the embedded FeNx C active sites in the carbon framework manifest in superior catalytic activity toward oxygen reduction reaction (ORR) compared to Pt/C catalyst in both alkaline and acidic media...

Children experience important cognitive control improvements in the transition to school. This study examined 4-5-year-olds' (n=17) and 7-8-year-olds' (n=22) ability to proactively deploy cognitive control. Children performed a cued task-switching paradigm presenting them with a cue indicating which attribute, color or shape, they should use to sort the upcoming stimulus. Following both cue and stimulus, we analyzed two event-related potentials: the P2 and P3, positive peaks reflecting sensory and attentional components of cognitive control, respectively...

The provision of mental health care has recently focused on the concept of recovery-oriented care. Clinical placements are important for imparting recovery-oriented knowledge and skills to students. However, it has been determined that not all clinical placements are beneficial for future nursing professionals. The aim of this study was to examine what elements of professional learning were facilitated by engagement in a recovery- and recreation-based clinical placement for pre-registration nursing students called Recovery Camp...

CONTEXT: The workplace can be a strenuous setting for residents: although it offers a wealth of learning opportunities, residents find themselves juggling their responsibilities. Even though supervisors regulate what is afforded to residents, the former find it difficult to strike the proper balance between residents' independence and support, which could create tensions. But what tensions do residents experience during clinical supervision and how do they cope with them to maximise their learning opportunities? Understanding how residents act on different affordances in the workplace is of paramount importance, as it influences their learning...

Religiosity, often measured as attendance at religious services, is linked to better physical health and longevity though the mechanisms linking the two are debated. Potential explanations include: a healthier lifestyle, increased social support from congregational members, and/or more positive emotions. Thus far, these mechanisms have not been tested simultaneously in a single model though they likely operate synergistically. We test this model predicting all-cause mortality in Seventh-day Adventists, a denomination that explicitly promotes a healthy lifestyle...

Fragmented services are a well-known problem in the mental health sector. Mental health service users' experiences of treatment and care can provide knowledge for developing more user-oriented continuity of care. We followed nine young adults with mental health illnesses and complex needs, conducting four interviews with each informant in the course of a year. The aim was to capture their experiences and views about treatment and care, focusing on (dis)continuities and episodes occurring through that year. The users' experiences were affected by shifts and transitions between institutions, units and practitioners while their need was predictability and stability...

INTRODUCTION: Healthcare research increasingly focuses on interprofessional collaboration and on shared decision making, but knowledge gaps remain about effective strategies for implementing interprofessional collaboration and shared decision-making together in clinical practice. We used Kuhn's theory of scientific revolutions to reflect on how an integrated interprofessional shared decision-making approach was developed and implemented over time. METHODS: In 2007, an interdisciplinary team initiated a new research program to promote the implementation of an interprofessional shared decision-making approach in clinical settings...
