Avascular Necrosis in Kidney Transplant Recipients is Associated With an Increased Risk of Patient Death.

Avascular necrosis is a debilitating osseous complication in transplant recipients. This program evaluation sought to describe risk factors and adverse outcomes of avascular necrosis in kidney transplant recipients. This was a retrospective evaluation of all recipients of kidneys and simultaneous pancreas and kidneys between 2001 and 2018 from a single center.

The Node of Ranvier as an Interface for Axo-Glial Interactions: Perturbation of Axo-Glial Interactions in Various Neurological Disorders.

The action potential conduction along the axon is highly dependent on the healthy interactions between the axon and myelin-producing glial cells. Myelin, which facilitates action potential, is the protective insulation around the axon formed by Schwann cells and oligodendrocytes in the peripheral (PNS) and central nervous system (CNS), respectively. Myelin is a continuous structure with intermittent gaps called nodes of Ranvier, which are the sites enriched with ion channels, transmembrane, scaffolding, and cytoskeletal proteins.

Discordance in cytomegalovirus viremia in kidney recipients from the same donor is associated with the worst outcomes.

Background: Cytomegalovirus (CMV) is a common viral infection in kidney transplant recipients (KTR) that has been associated with negative outcomes. The effect on outcomes of concordance versus discordance in CMV between two different recipients of kidneys from the same donor is largely unknown.

Methods: We reviewed all adult deceased donor kidney transplant recipients (DDKTs) for which both kidneys were transplanted to two different recipients at our center between 2014 and 2019.

Downward quantum learning from element 118: Automated generation of Fermi-Löwdin orbitals for all atoms.

A new algorithm based on a rigorous theorem and quantum data computationally mined from element 118 guarantees automated construction of initial Fermi-Löwdin-Orbital (FLO) starting points for all elements in the Periodic Table. It defines a means for constructing a small library of scalable FLOs for universal use in molecular and solid-state calculations. The method can be systematically improved for greater efficiency and for applications to excited states such as x-ray excitations and optically silent excitations.

Temporal Associations Between Posttraumatic Stress Symptoms and Depression in Response to Online Expressive Writing Interventions in a Hispanic Sample.

Some expressive writing (EW) interventions targeting posttraumatic stress symptoms (PTSS) may reduce both PTSS and comorbid depression symptoms. The temporal associations between PTSS and depression symptom levels in response to EW interventions are unknown. This study examined the directionality of PTSS and depression symptom levels from baseline to 1-week, 1-month, and 3-month follow-ups of two online EW interventions in a Hispanic sample with diverse trauma experiences.
