Children in Brunei Darussalam: their educational, legal and social protections
The past two decades of academic work, have cemented the idea that childhood is a social construction. As such, how children are conceptualized, educated, protected and interacted with differs from society to society, given the values inherent in each social construction. Culture, history and geography all influence the daily lives of children, and the inherent protections that children are offered in each society. This paper examines child protection provisions embedded in Brunei Darussalam by critically reviewing the sparse literature available. While much academic work has been done on Brunei Darussalam’s political system and unique ideology, little has been written on the children of Brunei. Specifically, the focus taken is on the protections offered by the Bruneian legal and education systems, family and cultural institutions, and on Brunei’s international commitments to ensuring child wellbeing
Triacylglycerol profiling of microalgae strains for biofuel feedstock by liquid chromatography–high-resolution mass spectrometry
Biofuels from photosynthetic microalgae are quickly gaining interest as a viable carbon-neutral energy source. Typically, characterization of algal feedstock involves breaking down triacylglycerols (TAG) and other intact lipids, followed by derivatization of the fatty acids to fatty acid methyl esters prior to analysis by gas chromatography (GC). However, knowledge of the intact lipid profile could offer significant advantages for discovery stage biofuel research such as the selection of an algal strain or the optimization of growth and extraction conditions. Herein, lipid extracts from microalgae were directly analyzed by ultra-high pressure liquid chromatography–mass spectrometry (UHPLC-MS) using a benchtop Orbitrap mass spectrometer. Phospholipids, glycolipids, and TAGs were analyzed in the same chromatographic run, using a combination of accurate mass and diagnostic fragment ions for identification. Using this approach, greater than 100 unique TAGs were identified over the six algal strains studied and TAG profiles were obtained to assess their potential for biofuel applications. Under the growth conditions employed, Botryococcus braunii and Scenedesmus obliquus yielded the most comprehensive TAG profile with a high abundance of TAGs containing oleic acid
Effects of bandwidth limitations on the localized state distribution calculated from transient photoconductivity data
The possible effects of experimental bandwidth limitation on the accuracy of the energy distribution
of the density of localized states (DOS) calculated from transient photoconductivity data by the
Fourier transform method is examined. An argument concerning the size of missing contributions to
the numerical Fourier integrals is developed. It is shown that the degree of distortion is not
necessarily large even for relatively small experimental bandwidths. The density of states calculated
from transient photodecay measurements in amorphous arsenic triselenide is validated by
comparing with modulated photocurrent data. It is pointed out that DOS distributions calculated
from transient photoconductivity data at a high photoexcitation density are valid under certain
conditions. This argument is used to probe the conduction band tail in undoped a-Si:H to energies
shallower than 0.1 eV below the mobility edge. It is concluded that there is a deviation in the DOS
from exponential at about 0.15 eV below the mobility edge
Reducing dose for digital cranial radiography : The increased source to the image-receptor distance approach
This investigation proposes that an increased source to the image-receptor distance (SID) technique can be used to optimize occipital frontal and lateral cranial radiographs acquired with direct digital radiography. Although cranial radiography is not performed on a routine basis, it should nonetheless be optimized to keep the dose to the patient as low as reasonably achievable, particularly because it can form part of the facial bone and sinus series. Dose measurements were acquired at various SIDs, and image quality was assessed using visual grading analysis. Statistically significant reductions in the effective dose between 19.2% and 23.9% were obtained when the SID was increased from the standard 100 to 150 cm (P ≤.05), and visual grading analysis scores indicate that image quality remained diagnostically acceptable for both projections. This investigation concludes that increasing the SID effectively optimizes occipital frontal and lateral skull radiographs. Radiology departments must be advised of the benefits of this technique with the goal of introducing an updated reference SID of 150 cm into clinical practice.Peer reviewe
Child protection with Muslim communities: considerations for non-Muslim-based orthodoxies/paradigms in child welfare and social work
The care and protection of children are a concern that crosses ethnic, religious and national boundaries. How communities act on these concerns are informed by cultural and religious understandings of childhood and protection. Islam has specific teachings that relate to the care and guardianship of children and are interpreted in diverse ways across the Muslim world. Islamic teachings on child-care mostly overlap with Western understandings of child protection, but there can be some contested positions. This creates complexities for social workers intervening in Muslim communities where the basis of their intervention is primarily informed by a non-Muslim paradigm or occurs in secular legal contexts. The purpose of this article is to address at a broad level the issue of how overarching concepts of child protection and Islam influence social work practice with Muslim communities. It addresses a gap in practical applications of the synergy of Islamic thinking with core social work practice in the field of child protection. For effective practice, it is argued that social work practitioners need to consider common ground in Islamic thinking on child protection
rather than rely on Western frameworks. This requires further research to build evidence-based practice with Muslim families
Weekend effect: analysing temporal trends in solid organ donation
Background: Research suggests patients treated over weekends experience poorer outcomes. Only one US-based study explored this weekend effect in organ donation, specifically the kidney discard rate. In Australia potential donors are referred to a donation service, and donation proceeds if family consent is granted and the donor is deemed medically suitable to donate. Organ procurement occurs when utilization is almost certain hence discard rates are much lower than in the USA. We aimed to characterize the effect of weekend referral on organ donation in Australia. Methods: We retrospectively reviewed all New South Wales Organ and Tissue Donation Service logs from 2010 to 2016. Our primary outcome was progression to organ procurement, and secondary outcomes were family consent and meeting medical suitability thresholds. We used logistic regression with random effects adjusting for clustering of referral hospitals. Results: Of 3496 potential donors referred for consideration, 694 (20%) progressed to organ procurement. There were fewer referrals on weekends (average 415 versus 588 for weekdays). However, donation rates were no lower for weekend compared to weekday referrals (adjusted OR 1.17; 95% CI 0.95, 1.44). Family consent (adjusted OR 1.20; 95% CI 1.00, 1.44) and medical suitability (adjusted OR 1.15; 95% CI 0.96, 1.38) were not lower for weekend compared to weekday referrals. Similar results were found for all sensitivity analyses conducted. Conclusions: In Australia, the donation pathway operates consistently throughout the week, with donation no less likely to proceed on weekends and holidays. This finding contrasts with findings in the USA

Hepatitis transmission risk IN kidney Transplantation (the HINT study); a cross-sectional survey of transplant clinicians in Australian and New Zealand
Background Interpreting hepatitis serology and virus transmission risk in transplantation can be challenging. Decisions must balance opportunity to transplant against potential infection transmission. We aimed to survey understanding among the Australian and New Zealand medical transplant workforce of hepatitis risk in kidney donors and recipients. Methods An anonymous, self-completed, cross-sectional survey was distributed via electronic mailing lists to Australian and New Zealand clinicians involved in kidney transplantation (2014-2015). We compared interpretation of clinical scenarios with paired donor and recipient hepatitis B virus and hepatitis C virus serology to recommendations in clinical practice guidelines. We used logistic regression modeling to investigate characteristics associated with decisions on transplant suitability in scenarios with poor (<50%) guideline concordance (odds ratios [OR]). Results One hundred ten respondents had representative workforce demographics: most were male (63%) nephrologists (74%) aged 40 to 49 years. Although donor and recipient hepatitis status was largely well understood, transplant suitability responses varied among respondents. For a hepatitis B virus surface antigen-positive donor and vaccinated recipient, 44% suggested this was unsuitable for transplant (guideline concordant) but 35% suggested this was suitable with prophylaxis (guideline divergent). In 4 scenarios with transplant suitability guideline concordance less than 50%, acute transplant care involvement predicted guideline concordant responses (OR, 1.69; P = 0.04). Guideline concordant responses were chosen less by hepatologists, intensive care doctors (OR, 0.23, 0.35, respectively; P = 0.01), and New Zealanders (guideline concordant responses OR, 0.17; P < 0.01; alternative responses OR, 4.31; P < 0.01). Conclusions Despite broadly consistent interpretations of hepatitis serology, transplant suitability decisions varied and often diverged from guidelines. Improved decision support may reduce clinician variability
Partial Anomalous Pulmonary Venous Connection: Diagnosis by Transesophageal Echocardiography
AbstractObjectives. This study sought to demonstrate that with proper technique, identification of the normal and abnormal pulmonary venous connection can be made with confidence using transesophageal echocardiography (TEE).Background. Partial anomalous pulmonary venous connection (PAPVC) is an uncommon congenital anomaly whose diagnosis has classically been made using angiography.Methods. We performed a retrospective review of all patients of all ages with PAPVC diagnosed at the Mayo Clinic who had undergone TEE because of either right ventricular volume overload or suspected intracardiac shunting by transthoracic echocardiography or intraoperatively.Results. A total of 66 PAPVCs were detected in 43 patients (1.5/patient); in 2 additional patients, TEE suggested, but did not diagnose, PAPVCs. Shortness of breath was the most common presenting symptom (42.2%), followed by heart murmur and supraventricular tachycardia. Right-sided anomalous veins were identified in 35 patients (81.4%), left-sided in 7 (16.3%) and bilateral in 1 (2.3%). There was a single anomalous connecting vein in 23 patients (53.5%), two in 18 (41.9%), three in 1 (2.3%) and four in 1 (2.3%). The connecting site was the superior vena cava (SVC) in 39 veins (59.1%), right atrial–SVC junction in 6 (9.1%), right atrium in 8 (12.1%), inferior vena cava in 1 (1.5%) and the coronary sinus in 2 (3.0%). Ten anomalous left pulmonary veins were connected by a vertical vein to the innominate vein (15.1%). Sinus venosus atrial septal defect (ASD) was the most common associated anomaly in 22 patients (49%), followed by ostium secundum ASD in 6 and patent foramen ovale in 4. Fifteen patients had an intact atrial septum. Thirty-one patients (68.8%) underwent surgical repair. PAPVC was confirmed in all patients, including the two whose TEE results were suggestive of PAPVC. All 49 PAPVCs detected by TEE preoperatively were confirmed at the time of operation.Conclusions. TEE is highly diagnostic for PAPVC and can obviate angiography. Accurate anatomic diagnosis may influence the need for medical and surgical management. TEE should be performed in patients with right ventricular volume overload when the precordial examination is inconclusive.(J Am Coll Cardiol 1997;29:1351–8
