Managing Calciphylaxis: Insights from Real-World Cases at a Tertiary Academic Center.

Calciphylaxis is a rare and potentially fatal condition involving chronic, nonhealing wounds caused by microvascular calcification. There is currently no approved treatment for calciphylaxis, contributing to its devastating impacts on quality of life. In this case series, the authors highlight instances of potentially misdiagnosed calciphylaxis in a cohort of patients and emphasize the importance of accurate diagnosis through multidisciplinary management approaches.

Frankenstein matrices: Among-population life history variation affects the reliability and predictions of demographic models.

Population matrix models are routinely used to study the demography of wild populations and to guide management choices. When vital rates are unknown for a specific population or life history stage, researchers often replace them with estimates from other populations of the same species. Such 'hybrid' matrices might ignore among-population life history variation and lead to incorrect inferences.

Incidence of dementia in the German Heinz Nixdorf Recall study over 20 years.

Introduction: The aim of the study was to estimate the population-based dementia incidence in Germany over a period of two decades.

Methods: We analyzed data from 4814 participants of the population-based Heinz Nixdorf Recall study (49.8% men, 45-75 years at baseline period 2000-2003), who have been monitored for the occurrence of cognitive decline and dementia.

Multi-microjoule broadband terahertz generation in the organic crystal BNA pumped by ytterbium laser pulses compressed via a gas-filled hollow-core fiber.

We investigate the enhanced terahertz generation in the organic crystal BNA when pumped by compressed high-energy ytterbium laser pulses. By compressing the pump pulses from 170 fs down to 43 fs using an argon-filled hollow-core fiber and chirped mirrors, the terahertz conversion efficiency is increased by 2.4 times, leading to the generation of multi-microjoule terahertz pulses with a frequency spectrum almost twice as wide, extending up to 19 THz.

Elevated Septal Native T1 Time in CMR Imaging Suggesting Myocardial Fibrosis in Young Kidney Transplant Recipients.

Background: Patients after kidney transplantation (KTx) in childhood show a high prevalence of cardiac complications, but the underlying mechanism is still poorly understood. In adults, myocardial fibrosis detected in cardiac magnetic resonance (CMR) imaging is already an established risk factor. Data for children after KTx are not available.
