Background And Aims: The complete pathological response (pCR) following neoadjuvant chemotherapy (NAC) in breast cancer is essential for the accurate prediction of prognosis. We aimed to evaluate the efficacy of the presence and type of peritumoral edema detected by magnetic resonance imaging (MRI) in predicting pCR to NAC in breast cancer patients.
Methods And Results: One hundred five patients with the diagnosis of invasive carcinoma were evaluated by MRI before NAC. Edema was evaluated in fat-suppressed T2-weighted images. The patients were categorized into three groups: patients with no peritumoral edema, patients with peritumoral edema, and patients demonstrating subcutaneous edema. The cases were categorized as being pCR and non-pCR. Molecular subtypes, lymphovascular invasion (LVI), tumor size, and apparent diffusion coefficient (ADC) were evaluated. A positive relationship was found between the presence of edema and tumor size. Subcutaneous edema was found to be statistically higher in non-pCR patients. While the number of pCR patients with subcutaneous edema was 17 (30.4%), the number of non-pCR patients with subcutaneous edema was 26 (53.1%) ( = 0.018). LVI was found to be statistically higher in patients with edema. The number of edema-negative and LVI (+) patients was 4 (15.4%), while the number of edema-positive and LVI (+) patients was 28 (35.4%) ( = 0.042). Intratumoral and peritumoral ADC values were significantly higher in tumors with edema.
Conclusion: The presence of subcutaneous edema and LVI may be utilized for the prediction of pCR outcomes in breast cancer patients scheduled for NAC treatment.

Background: Hereditary angioedema (HAE) is a rare genetic disease characterized by recurrent episodes of cutaneous or subcutaneous edema. There is clinical need for treatments that reduce the rate of HAE attacks in patients.
Objectives: Primary objectives were to evaluate the effectiveness of lanadelumab on attack free rate (AFR; proportion of patients who had zero HAE attacks), and on every two weeks (Q2W) and every four weeks (Q4W) adjustments on AFR.

Cases of sodium toxicosis (ST), although reported infrequently, can result in acute morbidity and mortality and extensive losses in affected poultry. We analyzed the clinical, pathologic, and toxicologic findings of 7 diagnosed cases of ST in chicken autopsy submissions at the California Animal Health & Food Safety Laboratory System (CAHFS), University of California-Davis, from 2014 to 2023. We also evaluated the brain sodium concentrations in 10 clinically normal broiler chickens to elucidate potential differences with salt-intoxicated chickens, and reviewed the literature of field cases of ST in chickens and turkeys.

Background: Gantenerumab is a fully human anti-amyloid-β (Aβ) immunoglobulin G1 monoclonal antibody for subcutaneous (SC) administration. The efficacy and safety of low-dose (105 mg or 225 mg) gantenerumab were investigated in SCarlet RoAD (SR; NCT01224106), a Phase III, double-blind (DB), placebo-controlled study in participants with prodromal Alzheimer's disease. Following a pre-planned futility analysis, SR was converted into an open-label extension (OLE) study.

: Dermatological complaints are commonly seen in the emergency department (ED) setting and may be attributed to infectious, inflammatory, allergic, hypersensitivity, or traumatic processes, yet few studies have been carried out in Saudi Arabia addressing this topic. This study, therefore, aimed to explore this issue by investigating the most common dermatology-related ED encounters in a large tertiary care center in Riyadh, Saudi Arabia, and estimating the incidence of these encounters. : This was a retrospective cohort study conducted in the ED of King Abdulaziz Medical City, a tertiary care center in Riyadh, Saudi Arabia.

Purpose: Visual evoked potentials (VEPs) are electrical signals generated at the visual cortex following visual stimulation. Flash VEPs (fVEPs) are produced by global retinal stimulation and are considered an objective measure of the integrity of the entire visual pathway. However, fVEP measurements are highly sensitive to external variables, making relative comparisons of the fVEP waveforms between the two eyes in the same individual challenging.
