Background: Cocaine is a risk factor for acute kidney injury and chronic kidney disease with progression to end-stage renal disease. Levamisole is an adulterant that is added to cocaine to enhance its euphoric effects. Levamisole-adulterated cocaine (LAC) is associated with the distinct clinical syndromes of agranulocytosis, leukocytoclastic vasculitis, cocaine-induced midline destructive lesions (CIMDL), and ANCA-associated vasculitis (AAV) with pauci-immune necrotizing glomerulonephritis.
Methods: We reviewed all cases of AAV secondary to LAC at our institution.
Results: We report 3 cases of AAV secondary to LAC and associated membranous nephropathy (MN). The first and second cases are concurrent AAV secondary to LAC and associated MN while the third case involves the development of MN after AAV secondary to LAC.
Conclusions: Clinicians should be aware of this novel association of LAC with MN.

Adeno-associated virus (AAV) gene therapy vectors are an accepted platform for treating severe neurological diseases. Test article (TA)-related and procedure-related neuropathological effects following administration of AAV-based vectors are observed in the central nervous system (CNS) and peripheral nervous system (PNS). Leukocyte accumulation (mononuclear cell infiltration > inflammation) may occur in brain, spinal cord, spinal nerve roots (SNRs), sensory and autonomic ganglia, and rarely nerves.

Skutterudite CoSb is an n-type thermoelectric material used in thermoelectric generators (TEGs) to recover and convert heat from various sources into electricity. For TEGs, such as CoSb, thermal stability is crucial, especially when exposed to high temperatures and varying environments. To synthesize high-purity nanostructured CoSb, an optimized solvothermal method was developed with detailed investigation of the influence of stoichiometry, solvent choice, and reaction duration on the formation mechanism, as revealed by Powder X-ray diffraction (PXRD).

Background: Traumatic brain injury (TBI) is a major public health concern with high morbidity and mortality rates. Secondary brain injury, marked by inflammatory responses and apoptosis, worsens TBI outcomes. The endoplasmic reticulum stress (ERS) response has been implicated in secondary brain injury, with Glutamine Rich 1 Gene (QRICH1) emerging as a potential mediator.

Secondary vasculitis is encountered in about one-third of all cases of systemic lupus erythematosus (SLE). Skin is most commonly involved in lupus-related small vasculitis. Although antineutrophil cytoplasmic autoantibodies (ANCA) associated vasculitis (AAV) is relatively uncommon, it can be the most dangerous manifestation associated with high mortality.

Objectives: We aimed to study the disease course, outcomes, and predictors of outcome in pediatric-onset anti-neutrophil cytoplasmic antibody (ANCA)-associated vasculitis (AAV) affecting the kidneys.
Methods: Patients eligible for this study had a diagnosis of granulomatosis with polyangiitis (GPA), microscopic polyangiitis (MPA), or ANCA positive pauci-immune glomerulonephritis, were ≤ 18 years at diagnosis, had renal disease defined by biopsy or dialysis dependence, and had clinical data at diagnosis and either 12- or 24-months. Ambispective data from the ARChiVE/PedVas Registry was used.
