The validation of a new articulator system for orthognathic model surgery
A review of the literature showed that the outcome of orthognathic surgery may differ from the planned outcome, that casts mounted on semi-adjustable articulators show systematic errors of orientation and that there may be a causal connection between them.
It was demonstrated that the movements of casts mounted on, and moved relative to, a standard articulator produced movements of different magnitudes relative to the natural head position. A mathematical model was developed to quantify the difference and the predictions of the resulting equations were confirmed in a photographic study using image analysis.
The second stage of the study compared a standard and the orthognathic articulator. Plastic model skulls were mounted at different angulations to represent different natural head positions. Casts of the maxillary teeth of the skulls mounted on the orthognathic articulator accurately reproduced the occlusal plane angles of the skulls, but those mounted on the standard articulator showed systematic errors of up to 28Âș. Surgical movements of the maxilla were reproduced using perioperative wafers constructed on casts mounted on the standard and orthognathic articulators. The accuracy of the maxillary repositioning was assessed at five anatomical reference points on the skulls. The results indicated that the orthognathic articulator was significantly more accurate than the standard articulator
The Fungal Frontier: A Comparative Analysis of Methods Used in the Study of the Human Gut Mycobiome
This research was conducted with the financial support of Science Foundation Ireland (SFI) under Grant Number SFI/12/RC/2273. PS is funded by a Royal Society-Science Foundation Ireland University Research Fellowship.peer reviewedThe human gut is host to a diverse range of fungal species, collectively referred to as the gut âmycobiomeâ. The gut mycobiome is emerging as an area of considerable research interest due to the potential roles of these fungi in human health and disease. However, there is no consensus as to what the best or most suitable methodologies available are with respect to characterizing the human gut mycobiome. The aim of this study is to provide a comparative analysis of several previously published mycobiome-specific culture-dependent and -independent methodologies, including choice of culture media, incubation conditions (aerobic versus anaerobic), DNA extraction method, primer set and freezing of fecal samples to assess their relative merits and suitability for gut mycobiome analysis. There was no significant effect of media type or aeration on culture-dependent results. However, freezing was found to have a significant effect on fungal viability, with significantly lower fungal numbers recovered from frozen samples. DNA extraction method had a significant effect on DNA yield and quality. However, freezing and extraction method did not have any impact on either α or ÎČ diversity. There was also considerable variation in the ability of different fungal-specific primer sets to generate PCR products for subsequent sequence analysis. Through this investigation two DNA extraction methods and one primer set was identified which facilitated the analysis of the mycobiome for all samples in this study. Ultimately, a diverse range of fungal species were recovered using both approaches, with Candida and Saccharomyces identified as the most common fungal species recovered using culture-dependent and culture-independent methods, respectively. As has been apparent from ecological surveys of the bacterial fraction of the gut microbiota, the use of different methodologies can also impact on our understanding of gut mycobiome composition and therefore requires careful consideration. Future research into the gut mycobiome needs to adopt a common strategy to minimize potentially confounding effects of methodological choice and to facilitate comparative analysis of datasets.Science Foundation Irelan
Valuing Arts-based Academic Projects in a Faculty of Nursing: Experiences of Graduate Students and Supervisors
Purpose: The purpose of this article is to explore student and supervisor experiences and perspectives regarding the advantages and challenges of arts-based projects in the context of graduate nursing education programs. We define arts-based academic projects as graduate level projects that incorporate a significant artistic component, and that culminate in a final written report of a capping exercise, a thesis or a dissertation. Procedures: Three graduate students were asked to briefly summarize their arts-based academic projects and to reflect upon their experiences with their projects, noting the advantages and challenges that they encountered in the process. The studentsâ supervisors also reported their experiences with supervising students conducting arts-based academic projects. The resulting written reflections were collated and summarized.
Results: The arts-based academic projects included a set of comics, a story-based digital education tool and a digital knowledge whiteboard animation video. All of these projects integrated visual art into products for the purpose of knowledge translation. The students and their supervisors identified numerous advantages to arts-based projects, such as being able to address the complexities of context and to engage broad audiences. They reported challenges such as misunderstanding and devaluing the nature of these less traditional academic projects.
Conclusions: This study has implications for future arts-based projects that may be conducted in Schools or Faculties of Nursing. Supervisors and committee members play a key role in fostering the creativity of students, building on their strengths, and encouraging them to pursue innovative theses or capping exercises. Similarly, graduate program coordinators/associate deans of graduate programs can also support these students by encouraging and approving projects that are less conventional and by helping others understand the value of these projects.

Health-related quality of life among adolescents with eating disorders
Objective
Health-related quality of life (HRQoL) is an emerging area of research in eating disorders (EDs) that has not been examined in adolescents in detail. The aim of the current study is to investigate HRQoL in an adolescent ED sample, examining the impact of ED symptoms on HRQoL.
Methods
Sixty-seven treatment-seeking adolescents (57 females) with anorexia nervosa (AN), bulimia nervosa (BN), or eating disorder not otherwise specified (EDNOS) completed self-report measures of HRQoL and ED symptoms.
Results
Participants reported poorer HRQoL in mental health domains than in physical health domains. Disordered attitudes, binge eating, and compensatory behaviors were associated with poorer mental health HRQoL, and body dissatisfaction was associated with poorer physical health HRQoL.
Conclusion
The current study assessed HRQoL among adolescents with EDs, finding several consistencies with the literature on adults with EDs. Future research should compare adolescents and adults with EDs on HRQoL
Drinking Water Sodium and Elevated Blood Pressure of Healthy Pregnant Women in Salinity-Affected Coastal Areas.
Coastal areas in Southeast Asia are experiencing high sodium concentrations in drinking water sources that are commonly consumed by local populations. Salinity problems caused by episodic cyclones and subsequent seawater inundations are likely (partly) related to climate change and further exacerbated by changes in upstream river flow and local land-use activities. Dietary (food) sodium plays an important role in the global burden of hypertensive disease. It remains unknown, however, if sodium in drinking water-rather than food-has similar effects on blood pressure and disease risk. In this study, we examined the effect of drinking water sodium on blood pressure of pregnant women: increases in blood pressure in this group could severely affect maternal and fetal health. Data on blood pressure, drinking water source, and personal, lifestyle, and environmental confounders was obtained from 701 normotensive pregnant women residing in coastal Bangladesh. Generalized linear mixed regression models were used to investigate association of systolic and diastolic blood pressure of these-otherwise healthy-women with their water source. After adjustment for confounders, drinkers of tube well and pond water (high saline sources) were found to have significantly higher average systolic (+4.85 and +3.62 mmâHg) and diastolic (+2.30 and +1.72 mmâHg) blood pressures than rainwater drinkers. Drinking water salinity problems are expected to exacerbate in the future, putting millions of coastal people-including pregnant women-at increased risk of hypertension and associated diseases. There is an urgent need to further explore the health risks associated to this understudied environmental health problem and feasibility of possible adaptation strategies
Application of real-time PCR to quantify hepatitis B virus DNA in chronic carriers in The Gambia
BACKGROUND/AIM: The study aimed at developing a real-time quantitative PCR assay to monitor HBV serum virus load of chronic carriers enrolled in therapeutic trials. METHOD: Quantitative real-time PCR assay was carried out using SYBR-Green signal detection and primers specific to the S gene. Thermal cycling was performed in an ABi 5700 sequence detection system. The assay was calibrated against an international HBV DNA standard and inter- and intra-assay reproducibility determined. Levels of viral load were monitored for 1-year in lamivudine treated carriers. Correlation between HBV DNA levels and HBeAg sero-status was determined in untreated carriers. RESULTS: The qPCR assay showed good intra- and inter-assay reproducibility over a wide dynamic range (1.5 Ă 10(3 )to 1.5 Ă 10(8 )copies/mL) and correlated well with those from a commercial assay (r = 0.91, (p < 0.001). Viral load levels dropped dramatically but temporarily during and after a short course of lamivudine therapy. HBV DNA was a more reliable indicator of the presence of virus than HBe antigen and was detected in 77.0% (161/209) of HBeAg negative and in all HBeAg positive carriers. CONCLUSION: This method is reliable, accurate, and reproducible. HBV DNA Quantification by qPCR can be used to monitor the efficacy of HBV therapy and useful in understanding the natural history of HBV in an endemic area
âIt Takes Two Hands to Clapâ: How Gaddi Shepherds in the Indian Himalayas Negotiate Access to Grazing
This article examines the effects of state intervention on the workings of informal institutions that coordinate the communal use and management of natural resources. Specifically it focuses on the case of the nomadic Gaddi
shepherds and official attempts to regulate their access to grazing pastures in the Indian Himalayas. It is often predicted that the increased presence of the modern state critically undermines locally appropriate and community-based resource management arrangements. Drawing on the work of Pauline Peters and Francis Cleaver, I identify key instances of socially embedded âcommonâ management institutions and explain the evolution of these arrangements
through dynamic interactions between individuals, communities and the agents of the state. Through describing the âliving spaceâ of Gaddi shepherds across the annual cycle of nomadic migration with their flocks I explore the
ways in which they have been able to creatively reinterpret external interventions, and suggest how contemporary arrangements for accessing pasture at different moments of the annual cycle involve complex combinations of the
formal and the informal, the âtraditionalâ and the âmodernâ
