We present justification and a rigorous procedure for electron partitioning among atoms in extended systems. The method is based on wave-function topology and the modern theory of polarization, rather than charge density partitioning or wave-function projection, and, as such, reformulates the concept of oxidation state without assuming real-space charge transfer between atoms. This formulation provides rigorous electrostatics of finite-extent solids, including films and nanowires.

Deep brain stimulation (DBS) for essential tremor is remarkably effective, leading to over 80% reduction in standardized tremor ratings. However, for certain types of tremor, such as those accompanied by ataxia or dystonia, conventional DBS targets have shown poor efficacy. Various rationales for using cerebellar DBS stimulation to treat tremor have been advanced, but the varied approaches leave many questions unanswered: which anatomic target, stimulation settings, and indications seem most promising for this emerging approach.

Infective endocarditis used to frequently cause mortality in subjects having PDA before the advent of antibiotics and surgical ligation. It has been documented that clinically silent PDAs may cause infective complications of heart valves. We present case of an 18-years-old male who presented with palpitations and fever to our emergency department.

Cholangitis, defined as the inflammation of the bile ducts, is the most frequent complication after Kasai hepatoportoenterostomy in patients with biliary atresia (BA). This review seeks to provide a comprehensive synthesis of current knowledge on diagnosing and managing BA-associated cholangitis while identifying gaps in the existing literature. A scoping literature review was conducted to gather global insights into the definition, evaluation, and management of post-Kasai cholangitis, illustrated through data from the Swiss Biliary Atresia Registry (SBAR).

is an intracellular protozoan parasite that infects a wide range of vertebrates, including humans. Although cats are the only definitive host, any warm-blooded animal can act as a paratenic host. Throughout the years, this apicomplexan parasite has been studied due to its wide prevalence, zoonotic potential, and host behavioral alterations.

Public health definitions of gambling-related harm include risks to family members and friends. This scoping review broadly aims to identify recent research on addressing gambling harm to adult affected others, focusing on prevalence, socio-demographic profiles, gambling profiles, and harm (Part I); and coping strategies, assessment, and treatment (Part II). A systematic search of electronic databases identified 121 studies published from 2000, with 82 focusing on coping strategies (22.
