As medical professionals, most of us face professional dilemmas that catch us unawares and are not discussed in medical training. One often learns about these dilemmas on one's own and deals with them with a common sense approach, rather than reflection. The professional dilemmas may concern receiving gifts from patients, handling issues of confidentiality or dealing with personal questions. There is seldom any formal instruction in competencies related to professionalism, especially in India. We adopted a team approach to provide training in these issues to postgraduate trainees in mental health and to engage them in discussion, using team feedback on snapshots of real-life professional situations, which were simulated through role play...

There is a battle in the supermarket isle, a battle between what the consumer wants and what the retailer and others want her to see, and subsequently to buy. Product packages and displays contain a number of features and attributes tailored to catch consumers' attention. These are what we call external factors comprising the visual saliency, the number of facings, and the placement of each product. But a consumer also brings with her a number of goals and interests related to the products and their attributes...

Population structures of fecal indicator bacteria (FIB) isolated from catch basins, a constructed wetland, and feces from a beef cattle feedlot were compared over a two-year period. Enterococcus hirae accounted for 92% of the fecal isolates, whereas secondary environments were characterized by greater relative abundance of environmentally adapted species including Enterococcus casseliflavus. While enterococci densities in the catch basins and wetland were similar under wet and drought conditions, E. hirae predominated during rainy periods while E...

Estimating a population's growth rate and year-to-year variance is a key component of population viability analysis (PVA). However, standard PVA methods require time series of counts obtained using consistent survey methods over many years. In addition, it can be difficult to separate observation and process variance, which is critical for PVA. Time-series analysis performed with multivariate autoregressive state-space (MARSS) models is a flexible statistical framework that allows one to address many of these limitations...

Recently, a hitherto unknown feeding strategy, the toxic mucus trap, was discovered in the dinoflagellate Alexandrium pseudogonyaulax. In this study, over 40 strains of 8 different Alexandrium species (A. ostenfeldii, A. tamarense, A. catenella, A. taylorii, A. margalefii, A. hiranoi, A. insuetum and A. pseudogonyaulax) were screened for their ability to ingest prey and/or to form mucus traps. The mucus trap feeding strategy, where a mucus trap is towed by the longitudinal flagellum remains unique to A. pseudogonyaulax...

BACKGROUND: A number of mosquito vectors bite and rest outdoors, which contributes to sustained residual malaria transmission in endemic areas. Spatial repellents are thought to create a protective "bubble" within which mosquito bites are reduced and may be ideal for outdoor use. This study builds on previous studies that proved efficacy of transfluthrin-treated hessian strips against outdoor biting mosquitoes. The goal of this study was to modify strips into practical, attractive and acceptable transfluthrin treated sisal and hessian emanators that confer protection against potential infectious bites before people use bed nets especially in the early evening and outdoors...

BACKGROUND: Natural red fluorescence is particularly conspicuous in the eyes of some small, benthic, predatory fishes. Fluorescence also increases in relative efficiency with increasing depth, which has generated speculation about its possible function as a "light organ" to detect cryptic organisms under bluish light. Here we investigate whether foraging success is improved under ambient conditions that make red fluorescence stand out more, using the triplefin Tripterygion delaisi as a model system...

Bioorthogonal coupling chemistry has been studied as one significant advantage for molecular imaging as it offers rapid, efficient, and strong binding, which may also benefit in stability, production, and chemical conjugation. The inverse-electron-demand Diels-Alder reaction between s-tetrazine and trans-cyclooctene (TCO) is an example of a highly selective and rapid bioorthogonal coupling reaction to be used successfully to prepare targeted molecular imaging probes. Herein, based on a two-step pretargeting bioorthogonal chemistry, we report a fast and reliable highly sensitive approach to achieve activated-platelet-specific CD62p targeted thrombus ultrasound molecular imaging...

Pheromone-based mating disruption has proven to be a powerful pest management tactic in many cropping systems. However, in the cranberry system, a viable mating disruption program does not yet exist. There are commercially available pheromones for several of the major pests of cranberries, including the cranberry fruitworm, Acrobasis vaccinii Riley (Lepidoptera: Pyralidae) and blackheaded fireworm, Rhopobota naevana (Hübner) (Lepidoptera: Tortricidae). Previous studies have shown that mating disruption represents a promising approach for R...

BACKGROUND: Both very preterm (VP; i.e., gestational age <32 weeks) and very low birth weight (VLBW; i.e., birth weight <1,500 grams) are used as inclusion criteria by studies on preterm birth. We aimed to quantify the impact of these entities on postnatal growth until final height. METHODS: Subjects born VP and/or with VLBW from the Project On Preterm and Small-for-gestational-age infants cohort were classified as: (1) VP+/VLBW+ (n=495), (2) VP+/VLBW- (n=207) or (3) VP-/VLBW+ (n=296) infants...

BACKGROUND: Children born small for gestational age (SGA) have higher serum dehydroepiandrosterone sulfate (DHEAS) concentrations than children born appropriate for gestational age (AGA). The overall metabolic risk associated with birth weight is U-shaped, but it is not known if children born large for gestational age (LGA) have elevated serum DHEAS levels. METHODS: A cohort of 49 LGA, 56 AGA, and 23 SGA children were studied at 5-8 years of age. Anthropometric data at birth, at the age of two years, and at examination were recorded...

Effective vector and arbovirus surveillance requires timely and accurate screening techniques that can be easily upscaled. Next-generation sequencing (NGS) is a high-throughput technology that has the potential to modernise vector surveillance. When combined with DNA barcoding, it is termed 'metabarcoding'. The aim of our study was to establish a metabarcoding protocol to characterise pools of mosquitoes and screen them for virus. Pools contained 100 morphologically identified individuals, including one Ross River virus (RRV) infected mosquito, with three species present at different proportions: 1, 5, 94%...

We carry out phase field simulations to study properties of the comblike step patterns induced by an adatom source. When an adatom source advances right in front of a step, step wandering is caused by the asymmetry of the surface diffusion field and small protrusions are formed. If the velocity of the source V_{p} is smaller than a critical value V_{p}^{c}, the protrusions follow the adatom source with coarsening of the step pattern, and a regular comblike pattern with finger-like protrusions is formed. With a sufficiently small V_{p}, the gap of the supersaturation is large at the adatom source...

CASE: A 54 year old woman with hypothyroidism presented with right flank pain that began acutely one week prior to presentation. She was told initially she had a urinary tract infection and treatment resulted in mild symptomatic improvement. The pain returned and she presented to another Emergency Department (ED); and was told the pain was due to constipation. She returned to the ED the next day when her pain worsened and her labs were notable for WBC of 19,000/uL, BUN/Cr of 28/0.75 mg/dL, AST of 31 U/L, ALT of 92 U/L and total bilirubin of 0...

Here, a novel potential-resolved "in-electrode" type electrochemiluminescence (ECL) immunosensor was fabricated based on two different types of luminant Ru-NH2 and AuNPs/g-C3N4 to realize simultaneous detection of dual targets. In this strategy, anti-CA1251 and anti-SCCA1 were immobilized on bare gold electrode as capture probes, which could catch the two corresponding target CA125 and SCCA, and the immobilization of the signal tags was allowed via the interaction between antigen and antibody. In this process, (Ru&anti-CA1252)@GO and anti-SCCA2-AuNPs/g-C3N4 could exhibit two strong and stable ECL emissions at 1...

BACKGROUND: Clinical decision rules can help to determine the need for CT imaging in children with head injuries. We aimed to validate three clinical decision rules (PECARN, CATCH, and CHALICE) in a large sample of children. METHODS: In this prospective observational study, we included children and adolescents (aged <18 years) with head injuries of any severity who presented to the emergency departments of ten Australian and New Zealand hospitals. We assessed the diagnostic accuracy of PECARN (stratified into children aged <2 years and ≥2 years), CATCH, and CHALICE in predicting each rule-specific outcome measure (clinically important traumatic brain injury [TBI], need for neurological intervention, and clinically significant intracranial injury, respectively)...
