Profound changes occur in the maternal circulation during pregnancy. Routine measures of arterial function - central systolic pressure (CSP) and augmentation index (AIx) - decline during normal human pregnancy. The objectives of this study were twofold: (1) explore wave reflection indices besides CSP and AIx that are not routinely reported, if at all, during normal human pregnancy; and (2) compare wave reflection indices and global arterial compliance (gAC) obtained from carotid artery pressure waveforms (CAPW) as a surrogate for aortic pressure waveforms (AOPW) versus AOPW synthesized from radial artery pressure waveforms (RAPW) using a generalized transfer function.

Although the rate of HIV infection among US prison inmates is considerably higher than that of the general population, little is known about age-related changes in HIV-infected inmates over the last decade. This study of the nation's largest state prison system examined (1) whether the mean age of the HIV-infected inmate increased over the last decade, and (2) whether the prevalence of HIV and associated comorbidities varied according to age. The study population included all 230,103 inmates incarcerated in the Texas prison system for any duration during 2014.
