Cone-Beam Computed Tomography-Guided Electromagnetic Navigation for Peripheral Lung Nodules.

Background: Electromagnetic navigation bronchoscopy (ENB) is a minimally invasive technology for the diagnosis of peripheral pulmonary nodules. However, ENB is limited by the lack of real-time confirmation of various biopsy devices. Cone-beam computed tomography (CBCT) could increase diagnostic yield by allowing real-time confirmation to overcome the inherent divergence of nodule location.

Risk perception and water purification practices for water-borne parasitic infections in remote Nepal.

This study assesses water-borne infection risk perception and water boiling habits in a remote Sankhuwasava region of Nepal using a brief interview-style questionnaire. All subjects were aware of the risks associated with drinking unpurified water, but a majority (65%) reported they did not boil water regularly, and almost 60% of villagers interviewed had history of infection despite their boiling practices. In contrast to reports from other communities in Nepal, risk awareness was sufficient in this region.
