The detection of ground-glass opacity (GGO) is increasingly common. Sufficient data have been accumulated to formulate recommendations for observation, intervention, and treatment modalities. However, an understanding of many nuances and uncertainties in the available data is needed to avoid making management errors. This article discusses the range of possible entities, risk factors and charac...

History has led us to believe that if we are overweight we are lazy, we are the problem and we should get off the couch and get moving. Although exercise is extremely important for weight optimization and health, nutrition is often the component that is not addressed correctly and leaves us in a recurring cycle of weight fluctuation and poor health. Recently a study showed that 80% of all worke...

Considerable focus has been devoted to how much antipsychotic is appropriate for optimal clinical response, although how often antipsychotics need to be administered is also less than clear. Clinicians are aware of the increased risk of relapse related to antipsychotic nonadherence/discontinuation, and current practice dictates continuous antipsychotic exposure with the goal of achieving steady...

Data Monitoring Committees (DMCs), sometimes referred to as Data & Safety Monitoring Boards, have had a successful history over four decades in both government and industry sponsored trials. Their primary mission is to independently evaluate the accumulating data in an on-going clinical for the risks and benefits on behalf of trial participants, investigators, sponsors and regulators. DMCs can ...

Analysis of ethnic differences in disease is complicated by the fact that culture has an effect on whether people identify themselves as ill and how often they use medical services. This paper cities evidence to show that use of selected medical services by older members of ethnic groups appears to be high. Although a relatively high amount of disease among minority ethnic groups partly account...

It is generally believed that students should use multiple representations in solving certain physics problems, and earlier work in PER has begun to outline how experts and novices differ in their use of multiple representations. In this study, we build on this foundation by interviewing expert and novice physicists as they solve two types of multiple representations problems: those in which mu...

Classic explanations of the "group polarization phenomenon" emphasize interpersonal processes such as informational influence and social comparison (Myers & Lamm, 1976). Based on earlier research, we hypothesized that at least part of the polarization observed during group discussion might be due to repeated attitude expression. Two studies provide support for this hypothesis. In Study 1, we ma...

Singleness, like its counterpart marriage, is a social construction. It is hard to pin down its meaning in a changing society – who is single? Are divorced, widowed, those in relationships to be included with the never-married in this catch all category? The experiences of single women, at least in part, result from the ways in which singleness and partnership are understood socially. In spite ...

The influence of child culpability on these ratings was also investigated. METHOD Ninety-nine New Zealand parents rated 12 physical discipline scenarios varying in discipline severity and perceived child c...
