Perceived effects of health status on sexual activity in patients with axial spondyloarthritis: a 5-year follow-up study.

Axial spondyloarthritis (ax-SpA) causes pain, fatigue, stiffness, loss of physical function, and poor health status, which can influence sexual activity and enjoyment. To explore whether patients with ax-SpA perceive that their health status effects their sexual activity and to identify predictors of these perceived effects on sexual activity after a 5-year follow-up. Data about demographics, disease, medication, health-related quality of life (HRQOL), and sexual quality of life (SQOL) were collected at the baseline and 5-year follow-up.

Enhancing the Efficacy of Radiation Therapy by Photochemical Internalization of Fibrin-Hydrogel-Delivered Bleomycin.

Background/objectives: Although the use of radiation-sensitizing agents has been shown to enhance the effect of radiation on tumor cells, the blood-brain barrier (BBB) impedes these agents from reaching brain tumor sites when provided systemically. Localized methods of sensitizer delivery, utilizing hydrogels, have the potential to bypass the blood-brain barrier. This study examined the ability of photochemical internalization (PCI) of hydrogel-released bleomycin to enhance the growth-inhibiting effects of radiation on multi-cell glioma spheroids in vitro.

Changes in Action Tremor in Parkinson's Disease over Time: Clinical and Neuroimaging Correlates.

Background: The various symptoms of Parkinson's disease (PD) may change differently over time as the disease progresses. Tremor usually manifests early in the disease, but unlike other motor symptoms, its severity may diminish over time. The cerebral mechanisms underlying these symptom-specific longitudinal trajectories are unclear.

Insurmountable antagonism of human mu opioid receptors by buprenorphine is due to hemi-equilibrium.

Buprenorphine is an FDA approved drug for the treatment of opioid use disorder and is a long-lasting, low efficacy (partial) agonist of the μ opioid receptor. As a partial agonist, buprenorphine can act as either an agonist or an antagonist depending on the efficiency of the cellular signaling system. Here we investigated the antagonist properties of buprenorphine using a genetically-encoded biosensor to monitor cAMP levels in real time in HEK293 cells expressing a relatively low density of the human μ receptor.

Frequency-to-Place Mismatch and Cochlear Implant Outcomes by Electrode Type.

Importance: Speech recognition outcomes with a cochlear implant (CI) are highly variable. One factor suggested to correlate with CI-aided speech recognition is frequency-to-place mismatch, or the discrepancy between the natural tonotopic organization of the cochlea and the electric frequency allocation of the CI electrodes within the patient's cochlea.

Objective: To evaluate the association between frequency-to-place mismatch and speech recognition outcomes in a large cohort of postlingually deafened adult CI users, while controlling for various clinical factors known to be associated with those outcomes.
