While the pathogenesis of giant cell arteritis (GCA) remains unclear, a number of factors may be contributory, including genetic, environmental, and immune. There have been few reports of GCA occurring in a conjugal pair, all originating from Northern Europe or the Northern United States. We document GCA occurring in a husband and wife from the southern Gulf Coast of the United States and discuss the implications of this, as well as the current understanding of the pathogenesis of GCA.

Department of Applied Physical Sciences, University of North Carolina at Chapel Hill, Chapel Hill, NC, 27599, USA.
Perovskite technologies has taken giant steps on its advances in only a decade time, from fundamental science to device engineering. The possibility to exploit this technology on a thin flexible substrate gives an unbeatable power to weight ratio compares to similar photovoltaic systems, opening new possibilities and new integration concepts, going from building integrated and applied photovoltaics (BIPV, BAPV) to internet of things (IoT). In this perspective, the recent progress of perovskite solar technologies on flexible substrates are summarized, focusing on the challenges that researchers face upon using flexible substrates.

Introduction: Giant cell arteritis (GCA) is a common vasculitis predominantly affecting larger vessels, especially in individuals aged 70-79. Cerebrovascular ischemic events (CIE), such as stroke and transient ischemic attacks, are serious but rare complications of GCA, with a pooled prevalence of 4%. Some studies found that within 2 weeks of GCA diagnosis, 74% and 34% of patients experience transient or severe ischemic events, respectively.

Background: Takayasu arteritis (TAK) and giant cell arteritis (GCA), the most common forms of large-vessel vasculitis (LVV), can result in serious morbidity. Understanding the molecular basis of LVV should aid in developing better biomarkers and treatments.
Methods: Plasma proteomic profiling of 184 proteins was performed in two cohorts.

Varicella, caused by the varicella-zoster virus (VZV), is rarely reported in the elderly but often complicates with pneumonia. In this case report, we present a case of varicella pneumonia in the elderly. A 60-year-old man presented to the emergency room with vesicles filled with clear fluid that had appeared all over the body for the past four days.
