Complex Management of Septic Joint and Cutaneous Nocardiosis in an Immunocompromised Patient: A Case Report.

, an opportunistic, gram-positive, catalase-positive, rod-shaped bacterium found in soil and water, is known to cause infections in humans, predominantly among immunocompromised individuals, through inhalation or direct inoculation. This report details a rare case of a septic joint caused by , which subsequently led to cutaneous involvement, in a patient with multiple underlying health issues. The management of this case was complicated by the patient's extensive medical history, including diabetes, chronic urinary tract infections, and recent surgical procedures, which necessitated a nuanced approach to antibiotic therapy.

Raman spectroscopy based molecular signatures of methamphetamine and HIV induced mitochondrial dysfunction.

METH and HIV Tat treatment results in increased oxidative stress which affects cellular metabolism and causes DNA damage in the treated microglia. Both, METH ± HIV Tat impair mitochondrial respiration, leading to dysfunction in bioenergetics and increased ROS in microglial cells. Our data indicate that mitochondrial dysfunction may be key to the METH and/or HIV Tat-induced neuropathology.
