Objectives: The coronavirus disease 2019 pandemic significantly affected Japanese society and the health of its population. Despite this, few studies have evaluated the influence of the pandemic on patients with neurological diseases or dementia, which we assessed through the Tochigi Dementia Cohort Study., Methods: Participants were divided into two groups. The pre-pandemic group included patients who were enrolled from December 1, 2016 to November 30, 2018, and were followed up until November 30, 2019 (i.e., before the pandemic). The post-pandemic group included patients who were enrolled from December 1, 2019 to November 30, 2021, and were followed up until November 30, 2022 (i.e., during the pandemic). We recorded their age, sex, mortality, and treatment withdrawal during the follow-up period. Furthermore, we examined their cognitive function at the baseline, and after 6 and 12 months., Results: A total of 384 patients were enrolled in this study, including 199 patients in the pre-pandemic group and 185 in the post-pandemic group. The mortality of dementia patients was significantly higher in the post-pandemic group than in the pre-pandemic group" (5.3% vs. 18.5%, p < 0.05*). The cognitive function scores at 12 months were also significantly lower in the dementia patients of the post-pandemic group than in those of the pre-pandemic group (p < 0.05*)., Conclusions: This longitudinal cohort study conducted in a local Japanese area revealed that mortality rate and cognitive function worsened in dementia patients during the pandemic., (Copyright © 2023 Elsevier B.V.

Background: While many studies focus on the prognosis of individual neurological diseases, very few comprehensively compare and analyze real-world data of these diseases., Objective: To address this gap in knowledge, in this study, we comprehensively analyzed the real-life data of patients with neurological diseases., Methods: We prospectively enrolled patients with neurological diseases at three hospitals from December 1, 2016 to September 30, 2020. Neurological diseases were classified into nine groups: Dementia, Cerebrovascular disease, Parkinson's and related, Functional, Spinocerebellar degeneration, Neuroimmune, Epilepsy, Muscle dystrophy disease, and Hypertension. Patients were followed up for three years, and their prognosis and evaluation of their cognitive function served as the endpoint., Results: A total of 426 patients were finally enrolled. Both mortality and cognitive function differed among the neurological disease categories. After 3 years, mortality was highest in the Dementia (25.5%), Parkinson's and related (21.6%), and Spinocerebellar degeneration (35.3%) groups while the cognitive function of patients in these three groups was significantly lowest., Conclusions: When the neurological diseases were holistically observed, both mortality and cognitive function of the Dementia, Parkinson's and related, and Spinocerebellar degeneration groups were significantly worse than the remaining diseases.

Objective: Combination therapy with glecaprevir and pibrentasvir (G/P) has been shown to provide a sustained virologic response (SVR) rate of >97% in patients with chronic hepatitis C virus (HCV) infection in the first published real-world Japanese data. However, a recently published study showed that the treatment was often discontinued in patients ≥75 years old, resulting in low SVR in intention-to-treat (ITT) analysis. Thus, our aim was to evaluate real-world data for G/P therapy in patients ≥75 years of age, the population density of which is high in "rural" regions. Patients and Methods: We conducted a multicenter study to assess the efficacy and safety of G/P therapy for chronic HCV infection, in the North Kanto area in Japan. Results: Of the 308 patients enrolled, 294 (95.5%) completed the treatment according to the protocol. In ITT and per-protocol analyses, the overall SVR12 rate was 97.1% and 99.7%, respectively. The old-aged patients group consisted of 59 participants, 56 of whom (94.9%) completed the scheduled protocol. Although old-aged patients tended to have non-SVR factors such as liver cirrhosis, history of HCC, and prior DAA therapies, the SVR12 rates in old-aged patients were 98.3% and 100% in the ITT and PP analyses, respectively. Of 308 patients enrolled, adverse events were observed in 74 patients (24.0%), with grade ≥3 events in 8 patients (2.6%). There was no significant difference in any grade and grade ≥3 adverse events between the old-aged group and the rest of the study participants. Only one patient discontinued the treatment because of adverse events. Conclusion: G/P therapy is effective and safe for old-aged patients., Competing Interests: N.M., T.M., Y.O., N.I., and H.Y. received lecture fees from AbbVie.

Objective Regional disparities were observed in the outcomes of interferon (IFN)-based therapy for chronic hepatitis C virus (HCV) infection in a Japanese nationwide study. However, whether or not these regional disparities are observed in the outcomes of direct-acting antiviral drugs, including sofosbuvir (SOF) plus ribavirin (RBV) therapy, remains unclear. Methods We conducted a multicenter study to assess the efficacy of SOF plus RBV therapy for HCV genotype 2 infection in Tochigi Prefecture and its vicinity, in which IFN-based therapy yielded a low sustained virologic response (SVR) rate. In addition, we divided Tochigi Prefecture into six regions to examine regional disparities in the SVR. Patients We enrolled patients with chronic HCV genotype 2 infection. Results Of the 583 patients enrolled, 569 (97.6%) completed the treatment, and 566 (97.1%) also complied with post-treatment follow-up for 12 weeks. The overall SVR12 rate was 96.1% by per protocol and 93.7% by intention-to-treat analyses. No marked differences were observed in the SVR12 between subjects ≥65 and <65 years of age. Although large gaps were observed in the characteristics of patients and accessibility to medical resources, there was no significant difference in the SVR12 rate among the six regions in Tochigi Prefecture. Conclusion SOF plus RBV therapy was effective for HCV genotype 2 infection in an area where IFN-based therapy had previously shown unsatisfactory results. In addition, no regional disparities in the SVR12 were observed in Tochigi Prefecture.

BACKGROUND Diabetic macular edema (DME) causes serious visual impairments in diabetic patients. The standard treatments of DME are intra-vitreous injections of corticosteroids or anti-vascular endothelial growth factor antibodies and pan-photocoagulation. These treatments are unsatisfactory in their effects and impose considerable physical and economic burdens on the patients. CASE REPORT A 63-year-old woman was diagnosed as type 2 diabetes with retinopathy 7 years ago. Before the initiation of an SGLT2 inhibitor, the dipeptidyl peptidase-4 inhibitor, sitagliptin (50 mg daily), and metformin (250 mg dai- ly) were used for her glycemic control. The level of her hemoglobin A1c had been controlled around 7%. She began to feel decreased visual acuity and blurred vision of her left eye 8 months before the visit to our clin- ic. She was diagnosed as DME, which turned out to be corticosteroid-resistant. Her visual acuity further de- creased to 20/50. Metformin was changed to ipraglifl (25mg/day). Her left visual acuity started to improve after 4 weeks of treatment with ipragliflozin and improved to 20/22 after 24 weeks. The macular edema did not change until 12 weeks of the treatment, however, it decreased prominently after 16 weeks. CONCLUSIONS In our patient with steroid-resistant DME, her visual symptoms and macular edema recovered after the initiation of an SGLT2 inhibitor. SGLT2 inhibitors might be a potential candidate for the DME treatment.

Background and Aim: Little is known about the clinical features of cardia varices (CV). The aim was to examine the background, bleeding risk, and post-treatment outcomes of CV in patients with portal hypertension., Methods: The subjects of this retrospective study were 277 patients (179 males, 98 females, 62.9 ± 11.5 years) with esophageal varices (EV). In patients with CV, there were 65 bleeders, and 95 patients received endoscopic treatment for primary or secondary prophylaxis., Results: There were 147 patients with CV (53.1%). The higher grade of EV (P < 0.01) and the lower grade of gastric fundal varices (FV) (P = 0.046) were significant factors for the presence of CV. Significant risk factors for bleeding were: the higher grade of EV (P < 0.01), red sign on EV (P < 0.01), lower albumin (P = 0.01), and Child-Pugh B/C (P < 0.01) for EV and red sign on CV (P < 0.01) and use of non-steroidal anti-inflammatory drugs (NSAIDs)/aspirin (P < 0.01) for CV. All CV disappeared by sclerotherapy combined with argon plasma coagulation or band ligation, and 20 patients (21.1%) in EV and 18 patients (18.9%) in CV had recurrences during the median observation period of 19.4 months. There was no significant difference in the cumulative survival rate between non-bleeders, bleeders from EV, and those from CV., Conclusions: The CV were closely associated with advanced grade of EV and less-advanced grade of FV. Further, usage of NSAIDs/aspirin and red sign were significantly related to the bleeding from CV, suggesting the need for careful management., (© 2014 Journal of Gastroenterology and Hepatology Foundation and Wiley Publishing Asia Pty Ltd.)
