Purpose: To determine the success rate of swept-source optical coherence tomography (SS-OCT) biometry (OA-2000) in elementary school students.
Methods: This was a prospective observational longitudinal study of 115 right eyes of elementary school students who were 8- to 9-years-old at the initial examination. Biometric measurements of the eyes were performed annually for three years, viz., during the third, fourth, and fifth grades. The success rates of obtaining data from optical biometric measurements of the axial length (AL), central corneal thickness (CCT), anterior chamber depth (ACD), lens thickness (LT), pupillary diameter (PD), corneal diameter (CD), and corneal curvature (CC) were determined.
Results: The AL, CCT, and CC could be measured in all images at the three measurement times in all subjects. The success rate of the measurements of the ACD was 92.2% in the third grade and 100% in the fourth and fifth grade. The LT was successfully measured in 88.7% in the third grade, 99.1% in the fourth grade, and 100% in the fifth grade. The PD was successfully measured in 100% of the third grade, 96.0% of the fourth grade, and 100% in the fifth grade. The CD was successfully measured in 84.3% in the third grade, 66% in the fourth grade, and 100% in the fifth grade.
Conclusion: SS-OCT can obtain accurate measures of all ocular parameters in the primary school students with high success rates. However, care should be taken especially in analyzing the ACD, LT, PD, and CD because errors can occur in some cases.

Background: The Prickle2 (Pk2) gene shows promising potential in uncovering the underlying causes of epilepsy, a neurological disorder that is currently not well understood. This paper utilizes the online tool PubMed to gather and condense information on the involvement of PCP channels and the associated roles of PCP pathway molecules in the onset of epilepsy. These findings are significant for advancing epilepsy treatment.

New treatment approaches are warranted for patients with advanced melanoma refractory to immune checkpoint blockade (ICB) or BRAF-targeted therapy. We designed BNT221, a personalized, neoantigen-specific autologous T cell product derived from peripheral blood, and tested this in a 3 + 3 dose-finding study with two dose levels (DLs) in patients with locally advanced or metastatic melanoma, disease progression after ICB, measurable disease (Response Evaluation Criteria in Solid Tumors version 1.1) and, where appropriate, BRAF-targeted therapy.

Background: Optimised use of kidney function information might improve cardiac risk prediction in noncardiac surgery.
Methods: In 35,815 patients from the VISION cohort study and 9219 patients from the POISE-2 trial who were ≥45 yr old and underwent nonurgent inpatient noncardiac surgery, we examined (by age and sex) the association between continuous nonlinear preoperative estimated glomerular filtration rate (eGFR) and the composite of myocardial injury after noncardiac surgery, nonfatal cardiac arrest, or death owing to a cardiac cause within 30 days after surgery. We estimated contributions of predictive information, C-statistic, and net benefit from eGFR and other common patient and surgical characteristics to large multivariable models.
Isolated third cranial nerve palsy in benign idiopathic intracranial hypertension.

Idiopathic intracranial hypertension (IIH) is marked by increased intracranial pressure without any accompanying evidence of clinical, imaging or laboratory findings of intracranial pathology. In addition to headache, nausea and vomiting, typical symptoms might also include diplopia, photophobia and blurred vision. Third nerve palsy is rarely linked to IIH, although sixth nerve palsy is reported in the majority of individuals with IIH.

Background: Systemic Arterial Hypertension (SAH), distinguished by a persistent elevation of blood pressure, emerges as a risk factor for stroke and Alzheimer's Disease (AD). Additionally, recent evidence suggests that stroke may adversely affect memory, potentially playing a role in the development of AD. This study aimed to investigate the influence of permanent focal ischemic stroke on memory, as well as on sensorimotor function (asymmetry of the front paws) and cerebral infarct size in adult male spontaneously hypertensive rats (SHR), compared to normotensive Wistar Kyoto (WKY) rats.
