Is hIV-induced immunosuppression associated with colonization of the proximal gut by environmental bacteria?
The colonization of the duodenum by environmental bacteria reflects loss of colonization resistance in HIV infection. Their correlation with CD4 cell counts suggests that compromised immunity could be responsible for the observed invasion by exogenous microbes.
The interatrial conduction time can be estimated with a relatively noninvasive method using P-LAA measurements. This technique can be applied widely in predicting AF recurrence, and appropriate therapy may be applied.
