Outpatient dermatology appointment wait times for United States military veterans, 2014-2021.

Trends in outpatient dermatology appointment wait times for United States (US) veterans are poorly characterized. Given concerns surrounding prolonged wait times at Veterans Health Administration (VHA) medical facilities, the federal government introduced the Maintaining Internal Systems and Strengthening Outside Networks (MISSION) Act in 2018, allowing veterans to receive VHA-reimbursed community care if VHA specialty care appointments cannot be scheduled within 28 days. Considering this expanded access to community care, we characterized among US veterans the (1) overall demand for dermatology appointments, (2) trends in average wait times, and (3) facility/geographic variation in wait times.

Effect of Activator Type on the High-Temperature Properties of Alkali-Activated Slag Cementing Fluid.

The type of activator has a significant impact on the performance of alkali-activated slag, and there is little research on the effect of activator type on the high-temperature performance of alkali-activated slag. The effects of activator type on the thickening time, compressive strength, and rheological properties of alkali-activated slag under a high-temperature condition were studied in this article. Six activators were designed using Ca(OH), NaCO, and NaSO and their combination.

PD-L1 testing patterns in recurrent/metastatic head and neck squamous cell carcinoma (R/M HNSCC) in the U.S.

Background: Pembrolizumab with/without platinum + 5-FU is approved for the first-line (1L) treatment of R/M HNSCC, and its monotherapy use requires PD-L1 Combined Positive Score (CPS) ≥ 1. We aimed to understand PD-L1 testing patterns and associations with patient characteristics and treatment choice in R/M HNSCC.

Methods: Adults with R/M HNSCC initiating 1L systemic therapy were included from a U.

Assembly and analysis of the first complete mitochondrial genome sequencing of main Tea-oil Camellia cultivars Camellia drupifera (Theaceae): revealed a multi-branch mitochondrial conformation for Camellia.

Background: Tea-oil Camellia within the genus Camellia is renowned for its premium Camellia oil, often described as "Oriental olive oil". So far, only one partial mitochondrial genomes of Tea-oil Camellia have been published (no main Tea-oil Camellia cultivars), and comparative mitochondrial genomic studies of Camellia remain limited.

Results: In this study, we first reconstructed the entire mitochondrial genome of C.

Continental drift triggered the Early Permian aridification of North China.

The boundary between wet and arid climate zones in the Tethys Ocean remains challenging to trace, complicating our understanding of global aridification pattern during the Late Carboniferous to Early Permian transition. The North China Block (NCB), situated in the Tethys Ocean, underwent a transition from humid to arid climate during the Early Permian, providing a rare opportunity to trace this climate boundary across this region. Here, we present paleomagnetic evidence indicating that the NCB underwent rapid northward drift between 290 and 281 million years ago.
