Outcomes and safety of Descemet's membrane endothelial keratoplasty (DMEK) as a surgical treatment for corneal endothelial dysfunction: A multicenter study.

Purpose: To analyze the outcomes and frequency of complications after Descemet's membrane endothelial keratoplasty (DMEK) and evaluate the parameters associated with the occurrence of these complications.

Methods: A multicenter retrospective study of 143 DMEK procedures performed consecutively by five surgeons between June 2018 and March 2021 was performed. Surgeon-specific surgical and graft characteristics were also assessed.

Characterization of focused ultrasound blood-brain barrier disruption effect on inflammation as a function of treatment parameters.

The technology of focused ultrasound-mediated disruption of the blood-brain barrier (FUS-BBB opening) has now been used in over 20 Phase 1 clinical trials to validate the safety and feasibility of BBB opening for drug delivery in patients with brain tumors and neurodegenerative diseases. The primary treatment parameters, FUS intensity and microbubble dose, are chosen to balance sufficient BBB disruption to achieve drug delivery against potential acute vessel damage leading to microhemorrhage. However, other safety considerations due to second order effects caused by BBB disruption, such as inflammation and alteration of neurovascular function, are only beginning to be understood.

Modelling the age pattern of fertility: an individual-level approach.

Fitting statistical models to aggregate data is still the dominant approach in many demographic and biodemographic applications. Although these macro-level models have proven useful for a variety of tasks, they often have no demographic interpretation. Individual-level modelling, on the other hand, offers a deeper understanding of the mechanisms underlying observed patterns.

Spine Pseudogout Following Breast Cancer Treatment: A Report of Two Cases.

Calcium pyrophosphate disease (CPPD) is a commonly diagnosed crystal-induced disease that typically presents as acute monoarticular or oligoarticular arthritis. It is less commonly seen in the spine, and its clinical importance in this area is still relatively understudied. Isolated spinal CPPD is quite rare; a diagnosis of spinal CPPD is almost always accompanied by peripheral CPPD.
