Quantification of Epstein-Barr virus (EBV) cell-free DNA (cfDNA) is commonly used in clinical settings as a circulating biomarker in nasopharyngeal carcinoma (NPC), but there has been no comparison with circulating tumour cells (CTCs). Our study aims to compare the performance of CTC enumeration against EBV cfDNA quantitation through digital PCR (dPCR) and quantitative PCR. 74 plasma samples from 46 NPC patients at baseline and one month after radiotherapy with or without concurrent chemotherapy were analysed...

REVIEW
Justin H Davies, Timothy Cheetham
The baby with atypical or ambiguous genitalia is usually born in secondary care. For most clinicians, this is an unfamiliar and challenging scenario with the potential for life-long ramifications arising from a consultation led by an unprepared clinician. Language needs to be used carefully with particular clarity when liaising with parents, local health professionals and the specialist multidisciplinary team. Confidence in the recognition and assessment of atypical or ambiguous genitalia in a newborn will guide the local clinician when deciding on the initial investigations required and is a foundation for subsequent management...

This work evaluated the effect of in vitro drought stress on morphological characteristics, phenolic compounds, flavonols, saponin content, and antioxidant activity in plantlets of Agave salmiana. Drought stress was induced with polyethylene glycol (PEG) at 0, 10, 20 and 30% w/v in Murashige and Skoog solid medium. The determination of specific flavonols and saponins was achieved via HPLC-DAD and HPLC-ELSD, respectively. Compared with the control, plants grown in 30% PEG showed a change in the width of the leaves and a different color, showing less clarity and more darkening (L = 21...

AIM: To report on an analysis on the concept of 'readiness for hospital discharge'. BACKGROUND: No uniform operational definition of 'readiness for hospital discharge' exists in the literature, therefore a concept analysis is required to clarify the concept and identify an up to date understanding of readiness for hospital discharge. Clarity of the concept will identify all uses of the concept; provide conceptual clarity, an operational definition and direction for further research...

EDITORIAL
Stef J Bloem, Bart O Roep
The role of B lymphocytes in the pathogenesis of type 1 diabetes in humans is not entirely evident. These cells are presumed to be important, but this assumption is largely based on animal models of autoimmune diabetes, where compelling evidence for the contribution of both B lymphocytes and insulin-specific autoantibodies to this disease is in place. For humans, this is much less the case; the exact way in which B lymphocytes and/or autoantibodies may contribute to type 1 diabetes is not yet known but the possibilities include a pathogenic function ('fire'), or they may represent a surrogate of loss of immune tolerance to beta cells ('smoke') or, indeed, they could be a marker of an attempt at immune regulation ('ice water')...

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)...

Wide-gauge posture of titanosauriform sauropods remains an enigmatic peculiarity among terrestrial vertebrates. Here, two-dimensional geometric morphometrics and thin plate splines analyses were used to quantitatively analyze shape differences among sauropodomorph humeri and femora to identify how these elements may differ according to body gauge. Results demonstrate that titanosauriforms generally possess proportionately gracile humeri in comparison to other sauropods, with relatively more medially oriented humeral heads and proximally located deltopectoral crests...

STUDY DESIGN: A retrospective radiographic study. OBJECTIVE: To investigate the reliability of using magnetic resonance imaging (MRI) to measure thoracic outlet parameters and whether supine MRI could supersede upright x-ray in measuring these parameters. SUMMARY OF BACKGROUND DATA: On x-ray, overlapped soft and bony tissues make sternum contour invisible. Thus, measuring thoracic inlet (TI) alignment on x-ray may be inaccurate. MRI could clearly show anatomy around TI...

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...

BACKGROUND AND AIMS: Lifestyle has been found to play an important role in the prevention of cardiovascular disease (CVD). There is evidence to suggest that if lifestyle factors are modified successfully, the relative risk of CVD can be reduced. Risk factors for CVD such as high blood pressure, diabetes mellitus and dyslipidaemias can be modified by lifestyle changes. The main aim of this article is to provide best practice approaches and support for healthcare professionals on the role of lifestyle changes in the prevention of CVD...

Research with non-clinical and clinical samples has examined how mindfulness concepts relate to psychological symptom presentations. However, there is less clarity when examining treatment-seeking patients who experience DSM-diagnosed anxiety and obsessional disorders - both cross-sectionally, and following empirically-supported treatments. The Five Facet Mindfulness Questionnaire (FFMQ; Baer, Smith, Hopkins, Krietemeyer, & Toney, 2006) conceptualizes mindfulness as consisting of five facets: Observing, Describing, Acting with Awareness, Nonreactivity, and Nonjudging...

BACKGROUND: As the cost of sequencing continues to fall, smaller groups increasingly initiate and manage larger sequencing projects and take on the complexity of data storage for high volumes of samples. This has created a need for low-cost laboratory information management systems (LIMS) that contain flexible fields to accommodate the unique nature of individual labs. Many labs do not have a dedicated IT position, so LIMS must also be easy to setup and maintain with minimal technical proficiency...

Rheology and atomic force microscopy (AFM) were employed to examine the microstructure of β-sitosterol:γ-oryzanol organogels in sunflower oil. Using time-resolved rheology, we followed gel formation, paying specific attention to the fibril aggregation process, which had not been studied in detail previously for this system. Using AFM, we observed gel structures directly and obtained detailed information on the gel structure, far exceeding previous studies. Our analysis suggests that though gels are formed by the self-assembly and aggregation of one-dimensional fibrils, the manner in which these fibrils aggregate into ribbons results in complex structures of higher dimensionality...

Research is increasingly pointing to the importance of extending the focus of childhood obesity intervention to include fathers, fathering figures, and other members of a child's primary parenting network. Advances in communication technology are now making it possible to achieve this aim, within current resources, using modalities such text messaging, web-based resources and apps that extend intervention to parents not in attendance at face to face interactions. However, published research is often unclear as to which parent/s they targeted or engaged with, whether interventions planned to influence behaviours and capabilities across family systems, and how this can be achieved...

Physical activity is increasingly being studied as a way to improve psychosocial outcomes (e.g., quality of life, self-efficacy, physical self-perceptions, self-esteem, body image, posttraumatic growth) among survivors of adolescent and young adult (AYA) cancer. Assessing levels of and associations between self-reported physical activity and psychosocial outcomes requires clear, appropriate, and relevant questionnaires. To explore how survivors of AYA cancer interpreted and responded to the following eight published questionnaires: Leisure Time Exercise Questionnaire, Exercise Self-Efficacy Scale, Physical Self-Description Questionnaire, Rosenberg Global Self-Esteem Scale, Multidimensional Body-Self Relations Questionnaire, Posttraumatic Growth Inventory, Functional Assessment of Cancer Therapy-General (FACT-G), RAND 36-Item Health Survey 1...

General practitioners (GPs) are increasingly managing patients with class 2 and 3 obesity (body mass index [BMI] > 35 and 40 kg/m(2) , respectively). Bariatric surgery is considered for patients with class 2 obesity and comorbidities or class 3 obesity where sustained weight loss using non-surgical interventions has not been achieved. In Australia, GPs facilitate access to surgery through referral processes, but the nature of GP involvement in bariatric pre- and post-surgery care is currently unclear...

Considerable advances in cancer-specific optical imaging have improved the precision of tumor resection. In comparison to traditional imaging modalities, this technology is unique in its ability to provide real-time feedback to the operating surgeon. Given the significant clinical implications of optical imaging, there is an urgent need to standardize surgical navigation tools and contrast agents to facilitate swift regulatory approval. Because fluorescence-enhanced surgery requires a combination of both device and drug, each may be developed in conjunction, or separately, which are important considerations in the approval process...
