BACKGROUND: As medical schools strive to improve the learning environment, it is important to understand medical students' perceptions of mistreatment. The purpose of this study was to explore student interpretations of previously reported mistreatment incidents to better understand how they conceptualise the interactions. METHODS: Medical students were presented with case scenarios of previously reported instances of mistreatment and asked to indicate their agreement as to whether the scenarios demonstrated mistreatment, using a five-point Likert scale (1, strongly disagree; 5, strongly agree)...

Lovisa Engberg, Kjell Eriksson, Anders Forsgren
The purpose of this study is to examine in a clinical setting a novel formulation of objective functions for intensity-modulated radiotherapy (IMRT) treatment plan multicriteria optimization (MCO) that we suggested in a recent study. The proposed objective functions are extended with dynamic multileaf collimator (DMLC) delivery constraints from the literature, and a tailored interior point method is described to efficiently solve the resulting optimization formulation. In a numerical planning study involving three patient cases, DMLC plans Pareto optimal to the MCO formulation with the proposed objective functions are generated...

Coalbed natural gas (CBNG) is an important unconventional natural gas resource with large reserves in China and receives much attention these years. The CBNG production is accomplished by extracting large volumes of produced water from the aquifer. The CBNG-produced water is commonly managed by discharging into nearby disposal ponds in the Southern Qinshui Basin (SQB), which provides an opportunity for water source for nearby irrigation, livestock, wildlife, and human drinking water. However, utilization of this nontraditional water source in the SQB is hindered by limited knowledge of water quality, practically oxidation/reduction potential (OPR), electrical conductivity (EC), sodium adsorption ration (SAR), and trace element chemistry data...

BACKGROUND: Iatrogenic ureteric injury is a serious complication of colorectal surgery. Incidence is estimated to be between 0.3 and 1.5%. Of all ureteric injuries, 9% occur during colorectal procedures. Ureteric stents are utilised as a method to reduce the risk of injury; however, these are not without risk and do not guarantee prevention of injury. Fluorescence is a safe and effective alternative for intraoperative ureteric localisation. This proof of principle study aims to assess the use of methylene blue to fluoresce the ureter during colorectal surgery...

Entropy effects play an important role in drug-target interactions, but the entropic contribution to ligand-binding affinity is often neglected by end-point binding free energy calculation methods, such as MM/GBSA and MM/PBSA, due to the expensive computational cost of normal mode analysis (NMA). Here, we systematically investigated entropy effects on the prediction power of MM/GBSA and MM/PBSA using >1500 protein-ligand systems and six representative AMBER force fields. Two computationally efficient methods, including NMA based on truncated structures and the interaction entropy approach, were used to estimate the entropic contributions to ligand-target binding free energies...

BACKGROUND: There is a growing body of evidence to support the utility of lung point-of-care ultrasound (POCUS) in pediatric patients with multiple pulmonary pathologies, particularly pneumonia. As we increase our use of lung POCUS for pediatric patients with respiratory complaints, we must be mindful of the normal anatomy and sonographic findings within the pediatric chest and aware of how to distinguish normal findings (e.g., thymus) from pathologic findings (e.g., consolidation). CASE REPORTS: We report four cases of pediatric patients who presented to the Emergency Department with respiratory complaints for which POCUS was able to distinguish lung consolidation and normal thymus in the anterior chest...

BACKGROUND: Cranial cruciate ligament rupture is a prevalent injury in dogs, and tibial plateau leveling osteotomy (TPLO) is one of the preferred surgical techniques. Surgical site infection is a possible complication following TPLO and measurement of serum acute phase proteins is suggested to be a way to early recognize and distinguish postoperative infectious complications from normal postoperative inflammatory conditions. In this study we investigate the changes in concentrations of the systemic inflammatory markers C-reactive protein (CRP) and serum amyloid A (SAA) following tibial plateau leveling osteotomy (TPLO) in dogs and evaluate if deviations from the changes expectedly induced by the surgical procedure are useful in early detection of post-surgical infections...

Mucoralean invasive fungal infections, while unusual among the general population, have a high mortality rate among immunocompromised individuals who become infected. They are also common spoilage organisms in cultured dairy products, some fresh produce, and baked goods. Additionally, Mucor and Rhizopus spp. are utilized in the production of traditional fermented foods including mold ripened cheeses and fermented soy products. The risk that consumption of these foods poses to immunocompromised consumers has been previously identified...

Liquid water (LW) existence in pure ice below 273 K has been a controversial aspect primarily because of the lack of experimental evidences. Recently, electron paramagnetic resonance (EPR) has been used to study deeply supercooled water in a rapidly-frozen polycrystalline ice. The same technique can also be used to probe the presence of LW in polycrystalline ice that has formed through a more conventional, slow cooling one. In this context, the present study aims to emphasize that in case of an external probe involving techniques such as EPR, the results are influenced by the binary phase (BP) diagram of the probe-water system, which also predicts the existence of LW domains in ice, upto the eutectic point...

This paper presents a study of the visual properties of natural and Amerindian cultural landscapes in late pre-colonial East-Guadeloupe and of how these visual properties affected social interactions. Through a review of descriptive and formal visibility studies in Caribbean archaeology, it reveals that the ability of visual properties to affect past human behaviour is frequently evoked but the more complex of these hypotheses are rarely studied formally. To explore such complex hypotheses, the current study applies a range of techniques: total viewsheds, cumulative viewsheds, visual neighbourhood configurations and visibility networks...

Case reports have a long-standing tradition in the current rheumatology literature. We aimed to present the main points of view regarding the importance, meaning, and barriers of consent for publishing under the comprehensive protection of patients' rights within this genre. We encourage Latin American editors and authors of rheumatology journals to adopt the best ethical practices in the field, avoiding security and legal liabilities from a regional perspective.
