Oxygen-Vacancy-Driven Persistent Luminescence in Mn-Doped MgGeO: Insights from X-Ray Absorption Fine Structure Spectroscopy.

Mn-doped MgGeO (MMGO) is a near-infrared-emitting persistent luminescence (PersL) phosphor. Its low luminescence decay has been linked to vacancies within the MgGeO host, likely associated with Ge, although no direct correlations have been confirmed. In this study, the Ge K-edge X-ray absorption fine structure (XAFS) spectroscopy is employed to investigate a series of MMGO submicron-sized particles with varying afterglow durations.

A 47-Year-Old Woman with Left Shoulder Pain.

AbstractMorning Report is a time-honored tradition where physicians-in-training present cases to their colleagues and clinical experts to collaboratively examine an interesting patient presentation. The Morning Report section seeks to carry on this tradition by presenting a patient's chief concern and story, inviting the reader to develop a differential diagnosis and discover the diagnosis alongside the authors of the case. This report examines the story of a 47-year-old woman who presented with pain in the left shoulder, fevers, and fatigue.

A Case of Rapidly Progressive Sensory Neuropathy.

A 62-year-old man presented with sensory neuropathy that evolved quickly over the course of weeks, starting with hand involvement and progressing to include the lower extremities and his torso. Nerve conduction studies were consistent with a demyelinating process. Spinal imaging showed cervical spondylotic myelopathy, and urgent surgical nerve decompression was performed.

Impact of Height Exponents on the Diagnosis and Prognosis of LVH: The REMODEL Study.

Background: Left ventricular hypertrophy (LVH) is a strong predictor of adverse outcomes. Although normalizing LV mass (LVM) to height exponents reduced variability from body size, specific recommendations for height exponents are lacking due to a scarcity of normal cohorts to define appropriate height exponents.

Objectives: The authors aimed to show the diagnostic and prognostic implications of establishing height exponents specific to sex, ethnicity, and imaging modality.

Enhanced Persistent Luminescence from Cr-Doped ZnGaO Nanoparticles upon Immersion in Simulated Physiological Media.

Near-infrared persistent luminescence (PersL) nanoparticles (NPs) have great potential in biomedical applications due to their ability to continuously emit tissue-penetrating light. Despite numerous reports on the distribution, biological safety and other consequences of PersL NPs in vitro and in vivo, there has been a lack of studies on the optical properties of these NPs in the physiological environment. In light of this, we investigated the effects of short-term immersion of the prominent Cr-doped ZnGaO (CZGO) NPs in a simulated physiological environment for up to 48 h.

A 6-Week-Old Boy With Irritability and Abdominal Distension.

A 6-week-old boy is brought to the hospital for fussiness and abdominal distension. He was febrile on presentation and was admitted to the hospital for further evaluation. On subsequent examinations, he continued to demonstrate abdominal distension and tenderness to palpation.

An Adolescent Boy With Hypoxia, Microscopic Hematuria, and Hypertension.

A 13-year-old boy presented with hypoxia, microscopic hematuria, and elevated blood pressures. Persistent microscopic hematuria and hypertension led to investigation of glomerular and non-glomerular causes of hematuria. After reviewing his clinical course, family history, and laboratory testing, an additional test was sent, revealing the diagnosis.

A 12-Year-Old Girl with Weight Loss.

A 12-Year-Old Girl with Weight LossThis report examines a case of chronic weight loss, anxiety, abdominal pain, and nausea in an adolescent girl. With directed questioning, physical examination, and testing, an illness script for the presentation emerges; the differential is refined until a final diagnosis is made.

Concurrent Acute, Subacute, and Chronic Cutaneous Rashes in a Patient with Systemic Lupus Erythematosus.

A 35-year-old woman with systemic lupus erythematosus presented with diffuse rashes. On exam, rashes of three different morphologies were seen throughout her body. A review of the cutaneous manifestations of lupus and the efficacy of belimumab for cutaneous lupus is provided.

Should Intravenous Fluids Be Administered During Hospitalizations for Sickle-Cell Disease?

Intravenous Fluids for Sickle-Cell DiseaseA 30-year-old woman with sickle-cell disease presents with diffuse pain in her arms, legs, and back. She has had frequent vaso-occlusive episodes, and this episode feels similar to previous ones. She is admitted for treatment, including with intravenous pain medications.
