Background: Cerebral autosomal dominant arteriopathy with subcortical infarctions and leukoencephalopathy (CADASIL) is the most common hereditary form of cerebral small vessel disease. It is clinically, radiologically, and genetically heterogeneous and is caused by mutations.

Methods: In this study, we analyzed in 368 patients with suspected CADASIL using next-generation sequencing. The significant variants detected were reported along with the clinical and radiological features of the patients.

Results: Heterozygous changes, mostly missense mutations, were detected in 44 of the 368 patients (~12%).

Conclusions: In this single-center study conducted on a large patient group, 30 different variants were detected, 17 of which were novel. CADASIL, which can result in mortality, has a heterogeneous phenotype among individuals in terms of clinical, demographic, and radiological findings regardless of the variant.

Background: Pre-cancer onset of cachexia raises uncertainties regarding the optimal timing for early intervention in lung cancer patients. We aimed to examine changes in physical function, nutritional status, and cachexia incidence in patients with lung cancer from the initial visit to treatment initiation and determine the effect of these changes on lung cancer treatment.

Methods: This single-center retrospective cohort study enrolled patients suspected of having advanced lung cancer who visited Kansai Medical University Hospital between January and February 2023 and were definitely diagnosed with the disease.

An unprecedented global outbreak caused by the monkeypox virus (MPXV) prompted the World Health Organization to declare a public health emergency of international concern on July 23, 2022. Therapeutics and vaccines for MPXV are not widely available, necessitating further studies, particularly in drug repurposing area. To this end, the standardization of in vitro infection systems is essential.

Introduction: Pseudotumors are benign lesions which may mimic like a malignant tumor on conventional imaging. They are formed in kidneys which are scarred and deformed by chronic pyelonephritis, glomerulonephritis, trauma or infarction. There is a diagnostic dilemma in most of the cases as to differentiate RCC and pseudotumors.
