#1
Kohei Sato, Takashi Ohnishi, Masashi Sekine, Hideaki Haneishi
PURPOSE: Tomosynthesis is attracting attention as a low-dose tomography technology compared with X-ray CT. However, conventional tomosynthesis imaging devices are large and stationary. Furthermore, there is a limitation in the working range of the X-ray source during image acquisition. We have previously proposed the use of a portable X-ray device for tomosynthesis that can be used for ward rounds and emergency medicine. The weight of this device can be reduced by using a flat panel detector (FPD), and flexibility is realized by the free placement of the X-ray source and FPD...

OBJECTIVE: The aim of this study was to identify nursing informatics competencies perceived as relevant and required by nurse leaders. BACKGROUND: To participate as a full partner in healthcare leadership among rapidly advancing health information technologies (HITs), nurse leaders must attain knowledge of informatics competencies related to their clinical leadership roles and responsibilities. Despite this increased need to engage in HIT-related decision making, a gap remains in validated informatics competencies specific to the needs of nurse leaders...

Bin Wang, Marc André Meyers
Only seldom are square/rectangular shapes found in nature. One notable exception is the bird feather rachis, which raises the question: why is the proximal base round but the distal end square? Herein, it is uncovered that, given the same area, square cross sections show higher bending rigidity and are superior in maintaining the original shape, whereas circular sections ovalize upon flexing. This circular-to-square shape change increases the ability of the flight feathers to resist flexure while minimizes the weight along the shaft length...

During volume-modulated arc therapies (VMAT), dosimetric errors are introduced by multiple open dynamic leaf gaps that are present in fixed diaphragm linear accelerators. The purpose of this work was to develop a methodology for adjusting the rounded leaf end modeling parameters to improve out-of-field dose agreement in SmartArc VMAT treatment plans delivered by fixed jaw linacs where leaf gap dose is not negligible. Leaf gap doses were measured for an Elekta beam modulator linac with 0.4 cm micro-multileaf collimators (MLC) using an A16 micro-ionization chamber, a MatriXX ion chamber detector array, and Kodak EDR2 film dosimetry in a solid water phantom...

RATIONALE: It is important for attendings to know which behaviors influence learner perceptions. To date, two studies focusing on general medicine attendings have been published addressing internal medicine residents' perceptions of attendings; there are no data on intensive care unit (ICU) attendings. OBJECTIVES: We sought to expand the evidence regarding this topic through a multicenter study at four geographically diverse academic medical centers. Our study focused on identifying the teaching behaviors of ICU physicians that learners observe in attendings they value as effective educators...

The filamentous fungus Alternaria alternata is a potent producer of many secondary metabolites, some of which like alternariol or alternariol-methyl ether are toxic and/or cancerogenic. Many Alternaria species do not only cause post-harvest losses of food and feed, but are aggressive plant pathogens. Despite the great economic importance and the large number of research groups working with the fungus, the molecular toolbox is rather underdeveloped. Gene deletions often result in heterokaryotic strains and therefore, gene-function analyses are rather tedious...

BACKGROUND: The unprecedented access to mobile phones in resource-poor settings has seen the emergence of mobile-health (mHealth) applications specific for low- and middle-income contexts. One such application is the Mobile Technology for Community Health Suite (MOTECH Suite). Given the importance of community health worker (CHW) perceptions of a health program toward its successful implementation, this study explores whether the introduction of an mHealth application, as a human resource management tool, is associated with changes in CHW perceived supervision, motivation, work engagement, and job satisfaction over time...

It is well understood that the success or failure of a mass drug administration campaign critically depends on the level of coverage achieved. To that end coverage levels are often closely scrutinised during campaigns and the response to underperforming campaigns is to attempt to improve coverage. Modelling work has indicated, however, that the quality of the coverage achieved may also have a significant impact on the outcome. If the coverage achieved is likely to miss similar people every round then this can have a serious detrimental effect on the campaign outcome...

Long-term cultivated Fagopyrum tataricum (L.) Gaertn. (Tartary buckwheat) morphogenic and non-morphogenic callus lines are interesting systems for gaining a better understanding of the mechanisms that are responsible for the genetic stability and instability of a plant tissue culture. In this work, we used histological sections and transmission electron microscopy to identify and describe the morphology of the nuclei of all of the analysed callus lines. We demonstrated that the embryogenic callus cells had prominent round nuclei that did not contain heterochromatin clumps in contrast to the non-morphogenic callus lines, in which we found nuclei that had multiple lobes...

PURPOSE: The implementation of an interprofessional clinical pharmacology selective (CPS) learning experience for pharmacy residents and medical students is described. SUMMARY: The opportunity for pharmacy residents to provide didactic lectures at a college of pharmacy and to develop teaching and preceptor skills with experiential pharmacy students may be limited by institution-specific affiliations and geographic location. In order to overcome these barriers, the Mayo Clinic Hospital postgraduate year 1 (PGY1) pharmacy residency program implemented an interprofessional learning experience in which pharmacy residents serve the role of preceptors for first- and second-year medical students on a CPS...

Socioeconomic inequalities in child undernutrition remain one of the main challenges in Bangladesh. The social determinants of health are mostly responsible for such inequalities across different population groups. However, no study has examined the relative contribution of different social determinants to the socioeconomic inequality in child undernutrition in Bangladesh. Our objective is to measure the extent of socioeconomic-related inequalities in childhood stunting and identify the key social determinants that potentially explain these inequalities in Bangladesh...

Clinicians who manage delirium must do so without key information required for evidence-based practice, not least lack of any clearly effective treatment for established delirium. Both the nature of delirium and the methods used to research it contribute to difficulties. Delirium is heterogeneous, with respect to motor subtype, aetiology, setting and the co-existence of dementia, and may be almost inevitable towards the end of life. Elements of assessment are subjective, so diagnosis can be uncertain or unreliable...
