Background: To evaluate the success rate and adverse effects of Gold Micro Shunt Plus (GMS+) implantation into the supraciliary space.
Methods: This retrospective study included 31 eyes of 31 patients diagnosed with severe glaucoma and uncontrolled intraocular pressure (IOP) with implantation of a GMS+ by means of a full-thickness scleral flap. The main outcome measures were surgical failure or success, based on the intraocular pressure and adverse effects. Clinical examination data are reported up to 4 years postoperatively.
Results: Thirty eyes (97%) met one of our criteria for failure. Within a mean of 7.3 ± 7.7 months another surgery was performed because of elevated IOP in 24 of 31 eyes (77%) and because of adverse effects in 2 (6%). The remaining 4 eyes, that met one of our criteria for failure, had an IOP reduction of less than 20% with comparable medication. Six GMS+'s were explanted; because of IOP elevation, 2; rubeosis iridis, 2; and low grade inflammation, 2.
Conclusions: GMS+ implantation is not an effective method to control IOP in patients with glaucoma, when using our surgical technique. The reason for the found signs of chronic low grade inflammation or rubeosis iridis in 4 eyes (13%) remains unknown and has to be further investigated.

Background: The vicious cycle between depression and dementia increases the risk of Alzheimer's Disease (AD) pathogenesis and pathology. This study investigates therapeutic effectiveness versus side effects and the underlying mechanisms of intranasal dantrolene nanoparticles (IDNs) to treat depression behavior and memory loss in 5XFAD mice.
Method: 5XFAD and wild-type B6SJLF1/J mice were treated with IDNs (IDN, 5 mg/kg) in Ryanodex formulation for a duration of 12 weeks.

Background: Although novel treatments for Alzheimer's disease (AD) have begun to show modest therapeutic effects, agents that target hallmark AD pathology and offer neuroprotection are desired. Erythropoietin (EPO) is a glycoprotein hormone with neuroprotective effects but is faced with challenges including limited brain uptake and increased hematopoietic side effects with long-term dosing. Therefore, EPO has been modified and bound to a chimeric transferrin receptor monoclonal antibody (cTfRMAb); the latter shuttles EPO past the blood-brain barrier (BBB) into brain parenchyma and reduces its plasma exposure and potential for side effects.

Anti-Aβ immunotherapies are controversial, in part because of high rates of serious side effects including edema, microhemorrhages, and siderosis, highlighting the importance of the development of alternative Aβ clearance strategy. Here, we introduce a bioinspired nanoparticle named MG-PE3 crossing the human blood-brain barrier (BBB) and clearing Aβ with no adverse effect.
View Article and Find Full Text PDFBackground: Patients with Alzheimer's disease (AD) often experience burdensome neuropsychiatric symptoms, including agitation which occurs in both home and long-term care (LTC) facilities, and is associated with substantial increases in caregiver burden and LTC placements. AXS-05 (45-mg dextromethorphan/105-mg bupropion), a novel, oral NMDA receptor antagonist and sigma-1 receptor agonist, approved by the FDA for major depressive disorder, is being investigated for treatment of AD agitation (ADA). AXS-05 has been evaluated in 2 randomized, double-blind studies: Phase 2 ADVANCE-1 (NCT03226522); Phase 3 ACCORD (NCT04797715).

Background: Mivelsiran (ALN-APP) is an investigational, intrathecally administered RNA interference therapeutic designed to lower levels of amyloid-β (Aβ) peptide, a key driver of Alzheimer's disease (AD) and cerebral amyloid angiopathy (CAA) pathogenesis, by reducing upstream production of amyloid precursor protein (APP). We report additional safety, pharmacodynamic, and biomarker data from the double-blind, placebo-controlled, single ascending dose part of the ongoing mivelsiran Phase 1 study (NCT05231785).
Method: Patients with early-onset AD (symptom onset <65 years of age, Clinical Dementia Rating global score 0.
