Statistical thermodynamic theory has recently been developed to account for the stabilities of globular proteins. Here we extend that work to predict the dependence on temperature. Folding is assumed to be driven by solvophobic interactions and opposed by the conformational entropy. The temperature dependence of the solvophobic interaction is taken from the transfer experiments on amino acids by Tanford and Nozaki and on model solutes by Gill and Wadsö. One long-standing puzzle has been why proteins denature upon heating, since the solvophobic force to fold strengthens with increasing temperature. This is resolved by the theory, which predicts two first-order phase transitions. "Cold denaturation" is driven principally by the weakening of the solvophobic interaction, but normal denaturation is driven principally by the gain of conformational entropy of the chain. Predictions of the thermodynamic state functions are in reasonable agreement with the calorimetric experiments of Privalov and Khechinashvili. Comparison of the theory with experiments suggests that there may be an additional enthalpic driving force toward folding which is not due to the solvophobic interactions.

Younger onset dementia (YOD) not only affects the person with the diagnosis but the whole family, which often includes young people. A limited body of research on this group of young people indicates that they experience varying degrees of emotional trauma. We explored the lived experiences of young people having a parent with YOD from the perspective of the social model of disability. Data was available from semi-structured interviews with 12 young people who had a parent with YOD looking at their lived experiences between 10 -24 years. Thematic analysis identified four main themes: the emotional toll of caring, keeping the family together, grief and loss and psychological distress. The social model of disability theory provides a helpful framework for these families who experience significant emotional distress, demonstrating that the disability is often socially constructed by a society, which marginalizes and excludes them. A 'whole family' approach is proposed, where the needs of young people and their parents are respected and responded to age appropriately.

Vitamin D3 supplementation led to a significant increase in serum 25(OH)D and decreased school days missed (p = 0.04), but no other advantageous changes in asthma parameters compared with PL. The potential adverse effect of vitamin D deficiency on growth and the potential negative effect of high serum 25(OH)D on pulmonary function warrant further investigation.

Background: Clinical Practice Guidelines (CPGs) synthesize the best available evidence to guide clinician and patient decision making. There are a multitude of barriers and facilitators to clinicians adhering to CPGs; however, little is known about active cancer treatment CPG adherence specifically. This systematic review sought to identify clinician attitudes, and perceived barriers and facilitators to active cancer treatment CPG adherence. Methods: A systematic search was undertaken of five databases; Ovid Medline, PsychInfo, Embase, Scopus, CINAHL, and PROQUEST. The retrieved abstracts were screened for eligibility against inclusion criteria, and a full text review was conducted of all eligible studies. Data were extracted, and a quality assessment was conducted of all included studies. The qualitative papers were thematically analyzed. Attitudes, barriers, and facilitating factors extracted from the quantitative papers were categorized within the qualitative thematic framework. Results: The search resulted in the identification of 9676 titles. After duplicates were removed, abstracts screened, and full texts reviewed, 15 studies were included. Four themes were identified which related to negative clinician attitudes and barriers to active cancer treatment CPG adherence: (1) concern over CPG content and currency of CPGs; (2) concern about the evidence underpinning CPGs; (3) clinician uncertainty and negative perceptions of CPGs; and (4) organizational and patient factors. The review also identified four themes related to positive attitudes and facilitators to active cancer treatment CPG adherence: (5) CPG accessibility and ease of use; (6) endorsement and dissemination of CPGs and adequate access to treatment facilities and resources; (7) awareness of CPGs and belief in their relevance; and (8) belief that CPGs support decision making, improve patient care, reduce clinical variation, and reduce costs.

We observed widespread vitamin D deficiency and insufficiency in a Caucasian, OSAS population. There were significant, independent, inverse relationships between 25(OH)D and AHI as well as nocturnal HR, a known cardiovascular risk factor. Further, 25(OH)D was significantly lower in OSAS cases compared to matched, non-OSAS subjects. We provide evidence that 25(OH)D and OSAS are related, but the role, if any, of replenishment has not been investigated.
