When it occurs, interaction skills training usually relies on peer-to-peer role playing or passive learning through videos. These forms of training lead to a critical training gap, because the students are limited in the practice time and the variety of scenarios that they encounter. But it is exactly this practice, studies show, that leads to significant onthe-job benefits. This paper describe...

Investigation of an outbreak of lead-poisoning in 121 Gurkha soldiers showed that this was due to the contamination of chilli powder (cayenne pepper), a constituent of curry powder, with lead chromate. Comprehensive systems of food sampling are needed in developing communities.

The contribution of each sample during model training varies across training iterations and the model’s parameters. We define the concept of sample importance as the change in parameters induced by a sample. In this paper, we explored the sample importance in training deep neural networks using stochastic gradient descent. We found that “easy” samples – samples that are correctly and confidentl...

The use of cardiac implantable electronic devices (CIED) has greatly increased over the past 2 decades. In parallel, there has been a growing need for device and lead extraction. The subsequent development of tools, techniques, and standards for transvenous lead extraction (TLE) has improved both the safety and efficacy of these procedures. However, these remain complex interventions that requi...

BACKGROUND Tetraethyl lead was phased out of gasoline in Uganda in 2005. Recent mitigation of an important source of lead exposure suggests examination and re-evaluation of the prevalence of childhood lead poisoning in this country. Ongoing concerns persist about exposure from the Kiteezi landfill in Kampala, the country's capital. OBJECTIVES We determined blood lead distributions among Kampa...

A rapid method for the determination of relative absorption of dietary lead by rats is described. The influence of age, weight and dose rate has been determined and using standard conditions the tissue lead content of blood, kidney and femur are significantly correlated with each other and are a function of ingested lead. Eight lead compounds were evaluated using this technique and the findings...

Background Undergraduate students who are interested in biomedical research typically work on a faculty member's research project, conduct one distinct task (e.g., running gels), and, step by step, enhance their skills. This "apprenticeship" model has been helpful in training many distinguished scientists over the years, but it has several potential drawbacks. For example, the students have lim...
