Article Abstract
Linear focal elastosis (LFE), characterised by horizontal streaks on the lower back, is a dermatological condition with unclear etiopathogenesis and limited epidemiological data. This study synthesises case reports to elucidate demographic patterns, clinical manifestations, and potential associations. A literature search across PubMed, Embase, Ovid and ResearchGate identified 37 relevant articles, yielding 80 cases after excluding duplicates and irrelevant articles. In analysis, the male-to-female ratio for LFE was 5:1, with a mean age of 39 years. Cases were more common among adolescents and older adults (age ≥ 60), with the majority occurring in pubertal adolescents. No racial predilection was observed. The lower back was the most frequently affected site, with rare cases involving other body parts. Some cases were associated with growth spurts or strenuous exercise, although the etiopathogenesis remains speculative. LFE may be underreported due to its asymptomatic nature and resemblance to other skin conditions, particularly striae distensae. Further research is required to clarify its pathogenesis and explore potential treatment options.

This study develops an integrated X-ray absorption spectroscopy (XAS) photoemission electron microscopy (PEEM) platform on beamline BL09U at the Shanghai Synchrotron Radiation Facility (SSRF), enabling nanoscale characterization of complex materials through energy-resolved imaging and local-area XAS. By using the wide range of energy tunability, full access to different polarizations and PEEM's surface sensitivity, we have established a gap-monochromator control system under the EPICS framework to synchronize the elliptically polarized undulator (EPU) gap and monochromator energy dynamically, optimizing photon flux stability for absorption fine structure analysis. Combining X-ray magnetic circular dichroism (XMCD) and X-ray magnetic linear dichroism (XMLD) with PEEM and local-area XAS, this platform achieves concurrent mapping of electronic structures and magnetic domains in ferromagnetic nano-patterns, as demonstrated through our studies of NiFe Permalloy using this system.

Diabetes mellitus (DM) is a chronic metabolic disorder characterized by persistent hyperglycemia with multiple clinical manifestations and complications, such as cardiovascular disease, kidney dysfunction, retinal impairment, and peripheral neuropathy. Continuous and minimally invasive glucose monitoring is essential for effective DM management. Microneedles (MNs)-based sensing platforms offer a promising solution; however, conventional polymeric MNs suffer from limited electrochemical sensitivity due to their insufficient electroactive surface area and inefficient loading of catalytic and enzymatic components.

Background: Poststroke cognitive impairment (PSCI) affects 30% to 50% of stroke survivors, severely impacting functional outcomes and quality of life. This study uses functional near-infrared spectroscopy (fNIRS) to assess task-evoked brain activation and its potential for stratifying the severity in patients with PSCI.
Method: A cross-sectional study was conducted at Nanchong Central Hospital between June 2023 and April 2024.

The Oncotype DX test is standardly used for patients with early-stage, hormone-receptor-positive, HER2-negative breast cancers to determine the benefit from chemotherapy and the likelihood of distant recurrence. The relationship between Oncotype DX recurrence scores and race/ethnicity is still being studied. This retrospective study aims to evaluate the relationship between Oncotype DX recurrence scores, race/ethnicity, and clinicopathological factors and to support the applicability of the Oncotype DX test for a diverse breast cancer population of Hawaii.
