We applied a classifier method to predict palladium catalysts for the formation of nonalternating polyketones via the copolymerization of CO and ethylene; current examples are limited to using phosphine sulfonate and diphosphazane monoxide supporting ligands. With the reported workflow, we discovered two new classes of palladium complexes capable of achieving the synthesis of nonalternating polyketones with a lower CO content than those made by known palladium catalysts. Our results show that we doubled the number of classes of palladium compounds that can catalyze the formation of this type of polymer.

Background And Objective: Stress urinary incontinence (SUI), defined as any involuntary leakage of urine associated with physical activity, remains underdiagnosed and undertreated. This review aims to provide an updated overview of the prevalence, diagnosis, and treatment of SUI in women, drawing upon recent evidence-based literature and clinical guidelines.
Methods: A systematic search of the MEDLINE database was conducted to identify only the most up-to-date and relevant studies published up to February 26, 2024, including the reference ESTER systematic review.

Background And Purpose: Symptoms indistinguishable from behavioral-variant frontotemporal dementia (bvFTD) can develop in patients with spontaneous intracranial hypotension associated with severe brain sagging. An underlying spinal CSF leak can be identified in only a minority of these patients and the success rate of nondirected treatments, such as epidural blood patching and dural reduction surgery, is low. The disability associated with bvFTD sagging brain syndrome is high and, because of the importance of the venous system in the pathophysiology of CSF leaks in general, we have investigated the systemic venous circulation in those patients with recalcitrant symptoms.
