Abstract: The present invention relates to the microbiomes of humans and other animals as biomarkers and therapeutic targets for regulation or altering of a microbiome profile associated with states of disease or disease risk, using additive and subtractive therapies aimed at restoring a microbiome profile associated with health, with reduced manifestations of disease, or with reduced disease risk. In particular, the invention provides methods of subtractive therapy using microorganism-specific avian egg yolk-derived immunoglobulins (IgY) in a fashion that titrates, without necessarily eliminating, populations of microorganisms known to be associated with human gut and extraintestinal diseases.

Abstract: An effort-independent, portable, user-operated capnograph device for evaluating a pulmonary status of a user. At least one baseline measurement is stored within a memory of the capnograph device. The identity of a user of the capnograph device is verified to prevent miss-use. Concentrations of carbon dioxide (CO2) exhaled by the user when breathing normally are sensed and stored within the memory. The stored data is compared with the at least one of the baseline measurements to determine the pulmonary status of the user, and the determined pulmonary status is indicated to the user.
