Validity of the Tablet-Based Digital Cognitive Test (SCST) in Identifying Different Degrees of Cognitive Impairment.
As society ages, the incidence of Alzheimer's disease and other dementias has surged, highlighting the importance of early dementia diagnosis. The Seoul Cognitive Status Test (SCST), a digital neuropsychological test, is designed for the early detection of cognitive impairment and has been standardized to establish reliability and validity. This study aims to verify whether the SCST effectively discriminates between groups based on three cognitive statuses (subjective cognitive decline [SCD], mild cognitive impairment [MCI], Dementia) in a large sample. We also seek to determine whether the SCST discriminates between individuals with three different cognitive statuses as defined by the Cognitive Dementia Rating (CDR). ⋯ This study reaffirmed that the SCST can significantly discriminate between groups of individuals with SCD, MCI, and dementia based on a large sample. Furthermore, differences in SCT scores were found across the levels of CDR, confirming the clinical utility of the SCST. These findings suggest that the SCST is an efficient and useful neuropsychological test for the sensitive detection of early cognitive impairment.

Modified Albumin-Bilirubin Grade After Curative Treatment: Predicting the Risk of Late Intrahepatic Recurrence of Hepatocellular Carcinoma.
We aimed to identify the prognostic factors for late intrahepatic recurrence (IHR), defined as recurrence more than two years after curative treatment of newly diagnosed hepatocellular carcinoma (HCC). ⋯ After curative treatment for newly diagnosed early HCC, the mALBI grade at three and six months after initial curative treatment, as well as at baseline, was one of the most crucial prognostic factors for late IHR.

Observational StudyEffectiveness of the Bivalent mRNA COVID-19 Vaccine for Preventing Critical Infection From the SARS-CoV-2 Omicron Variant in the Republic of Korea.
This retrospective observational matched cohort study assessed the differences in critical infections caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) during the omicron-predominant period of the coronavirus disease 2019 (COVID-19) pandemic. We evaluated the vaccine effectiveness of bivalent mRNA vaccine compared to unvaccinated individuals. ⋯ Our findings indicate that the bivalent vaccine reduces the disease burden of the SARS-CoV-2 omicron variant, particularly among the older population. Further studies are warranted to determine the effectiveness of booster doses of vaccines for SARS-CoV-2 infection.

LETter To the EditoR Standards (LETTERS): Considerations for Authors, Reviewers, and Editors.
Correspondence in the form of letters to the editor serves multiple scholarly purposes, including critiquing previously published articles, engaging in discourse with other correspondents, commenting on the journal's structure or style, and contributing insights for future publications. The composition of such letters warrants meticulous attention, as they play a crucial role in fostering communication between the journal and its readership. Adherence to specific principles is essential in crafting an effective letter to the editor. ⋯ The content should be constructive in nature and substantiated by rigorous scientific evidence and appropriate citations. The structure of a letter to the editor typically encompasses several key components: a title, an opening section, the main body of the correspondence, a closing statement, and a list of references. This article aims to establish Letter to the Editor Standards as a comprehensive guide for authors, reviewers, and editorial boards, thereby enhancing the quality and impact of this crucial form of academic discourse.

Masticatory Function, Sex, and Risk of Dementia Among Older Adults: A Population-Based Cohort Study.
A decline in masticatory function may indicate brain dysfunction related to dementia, but the relationship between masticatory function and dementia risk remains unclear. This study aimed to investigate whether masticatory function is associated with the risk of cognitive decline and dementia. ⋯ Older men who frequently chew their meals could be considered a notable population at risk for dementia who should be carefully assessed for their cognitive trajectories.
