Abstract In Japan, antiviral agents for COVID-19 were freely available until September 2023 as part of national policy. This study evaluated changes in these agents’ prescribing patterns and the patient outcomes following the policy shift. We conducted a multicenter retrospective study at four hospitals in Japan’s Okayama and Kagawa prefectures from January 2022 to March 2024. The study period was divided into the public-expenditure phase (January 2022 to September 2023) and the post-expenditure phase (October 2023 to March 2024). We extracted the hospitalized patients’ clinical data from the electronic database. The study’s primary outcome was the antiviral prescription rate; the secondary outcome was in-hospital mortality. Among the 302 hospitalized patients (median age 85 years), 52.0% were classified as having a mild condition. Of the patients with mild conditions, 37.7% were diagnosed in outpatient settings prior to hospitalization. During the public-expenditure phase, 47.4% of the patients received antivirals as outpatients, mainly molnupiravir (80.9%). In the post-expenditure period, 80.0% of the patients were prescribed antivirals, mostly molnupiravir (91.7%). The antiviral prescription rate was significantly higher after the policy change. The overall in-hospital mortality was 15.8%, with no significant difference between the two periods (17.0% vs. 10.5%). Despite the termination of government funding, antiviral prescriptions remained frequent at community hospitals located in highly aging regions of western Japan such as Okayama and Kagawa prefectures. Mortality remains high among the elderly, highlighting the need for continued antiviral therapy and booster vaccinations.

Abstract Deregulation of cannabis use is gradually expanding in Europe and the United States. However, the biological processes driving tolerance to delta-9-tetrahydrocannabinol (Δ9-THC), the main psychoactive component of cannabis, remain unclear. Thus, this study aimed to investigate the mechanisms and time course of tolerance development and loss to Δ9-THC in mice. Male ICR mice (7 weeks old) were administered Δ9-THC once daily for 3 days and then divided into three groups according to the washout period (3-, 10-, and 17-day washout groups). After each washout, changes in body temperature and locomotor activity were measured following re-exposure to Δ9-THC. Furthermore, the mRNA expression levels of CB1 and CB2 receptors in the brain were evaluated using real-time PCR. On day 1, significant hypothermia and reduced spontaneous locomotor activity were observed in the Δ9-THC-treated mice compared with the vehicle-treated mice. Tolerance to the hypothermic and locomotor-suppressing effects of Δ9-THC developed on days 2 and 3, respectively, and dissipated after 3 and 11 days of washout, respectively. These differences in the rates of tolerance development and recovery may reflect distinct underlying mechanisms. No significant changes in receptor mRNA expression were observed. These findings highlight the complexity of Δ9-THC tolerance and its potential implications for long-term cannabis use.

Abstract We investigated global alignment changes following total hip arthroplasty (THA) and predictive alignment parameters for increased cup anteversion (CA) by retrospectively analyzing the primary THA data of 75 patients treated at our hospital (49 women, 26 men; age 65.1±5.7 years, BMI 28.3±3.4 kg/m2). Global alignment parameters, i.e., the anterior pelvic plane angle (APPa) and proximal femoral shaft angle (PFSa) and other alignment parameters were measured. CA was evaluated based on the patients’ standing coronal radiographs. ΔCA was defined as the difference in CA from 2 weeks before to 1 year after each THA. We classified the cases as stable (S) (CA < 10°; n=63) and pelvic retroversion (R) (CA ≥ 10°; n=12) groups. Associations between ΔCA and alignment parameters were evaluated by linear regression and a receiver operating characteristic (ROC) analysis. A significant decrease in the PFSa occurred between the 2-week and 1-year post-THA timepoints (7.8±4.3° vs. 4.2±3.6°, p<0.001), with no notable change in other alignment parameters. At 1-year post-THA, the CA of 12 (16%) patients had increased to 4.5±4.4°. Only the preoperative APPa was positively associated with ΔCA (β=0.165, p=0.020). The ROC analysis revealed that the optimal cut-off value for increased CA in the APPa is 2.1° (area under the curve, 0.700; p=0.020; odds ratio, 4.80). The APPa change predicted increased CA, which emphasizes the importance of the use of preoperative standing radiography for identifying the optimal cup positioning for post-THA changes in CA.

Abstract Appropriate treatments for chronic hemodialysis patients are a public health challenge in Japan. Sedentary behavior appears to be closely associated with these patients’ survival. We thus sought to develop a nomogram that predicts survival based on the duration of chronic hemodialysis patients’ sedentary behavior. One hundred twenty-four patients under chronic hemodialysis (73 men, 51 women, age 71.7±11.1 years) were enrolled in this cohort study. The patients wore a triaxial accelerometer that measured both their sedentary behavior, i.e., total sedentary behavior (minutes) and their maximum sedentary bouts (min) on non-hemodialysis days. We obtained the Kaplan-Meier curve and used the log-rank test and a Cox proportional hazards model to evaluate the relationship between the patients’ sedentary behavior and their survival. We also used a Cox proportional hazards model to develop a nomogram for the patients’ 5-year survival rate. Forty-six patients died during the follow-up period. When we stratified the patients by the medians of total sedentary behavior and maximum sedentary bouts, we observed significant between-group differences. After adjustment for confounding factors in a Cox proportional hazards model, total sedentary behavior and maximum sedentary bouts were identified as critical survival factors, and we generated a nomogram using an index of sedentary behavior. Our analysis results demonstrated that sedentary behavior on non-dialysis days was closely associated with the survival of the chronic hemodialysis patients, suggesting that a decrease in sedentary behavior would prolong their survival. The nomogram developed herein based on sedentary behavior may be useful for predicting the outcomes of chronic hemodialysis patients.
