The aim of this study was to determine whether pulse pressure (PP), an indicator of arterial stiffness, was independently associated with the risk of acute kidney injury (AKI) following intracerebral hemorrhage (ICH). We enrolled patients with acute ICH from a multicenter stroke registry in Fukuoka, Japan, from June 2007 to September 2019. The mean PP, measured three times on the third day after admission, was categorized into three groups based on tertiles: G1 < 54 mmHg, G2 54-64 mmHg, and G3 ≥ 65 mmHg.

At the Fukushima Daiichi Nuclear Power Station (FDNPS), continuous water circulation cools fuel debris, leading to the presence of radionuclides such as Sr-30, Cs-137, and I-129 in the cooling water. These radionuclides are adsorbed and co-precipitated by various materials. Among them, I-129 is a key radionuclide for safety assessment during the final disposal of adsorbent and co-precipitation materials, owing to its long half-life and poor sorption.

Rationale: Although the mortality of severe coronavirus disease 2019 (COVID-19) has decreased after the emergence of the Omicron variant, it remains high in patients on hemodialysis (HD). Remdesivir (RDV) is considered as the first line drug for hospitalized COVID-19 patients, however the evidence regarding the usage in HD patients is lacking because clinical trials of RDV have excluded HD patients for safety reasons. Thus, accumulation of knowledge on the regimen, efficacy, and tolerability of RDV in HD patients is important.

Objectives: The right posterior segment graft can be selected in cases where neither the right nor left lobe graft satisfies the selection criteria for adult living donor liver transplant. However, vascular and biliary anatomy may cause technical difficulties in procurement of posterior segments in donors of living donor liver transplant and may require specific attention in vascular and biliary reconstruction in the recipient. In this study, we examined the feasibility of right posterior segment grafts in adult living donor liver transplants through donor safety and recipient outcomes and clarified the anatomic points of the surgical technique.

Article Synopsis
  • Hospital-associated disability (HAD) is a decline in the ability to perform daily activities during hospitalization, particularly affecting older adults. This study investigates how inpatient cardiac rehabilitation (CR) impacts the development of HAD in older patients undergoing transcatheter aortic valve implantation (TAVI).
  • Out of nearly 20,000 patients studied, those who participated in CR had a significantly lower prevalence of HAD (8.8%) compared to non-participants (14.2%), suggesting CR is beneficial in preventing this decline.
  • However, the positive effects were less pronounced in patients with low body mass index (BMI) or lower Barthel Index (BI) scores at admission, indicating some patients might not benefit as much from CR.

In cases of moderate to severe atopic dermatitis that does not respond to topical therapy, temporary systemic administration of molecular targeted drugs (biological agents or oral Janus kinase[JAK]inhibitors) may be necessary. However, topical therapy forms the basis of the treatment for atopic dermatitis, and if topical therapy is appropriately established with long-term remission achieved, the use of molecular targeted drugs can be discontinued. In these two cases of severe adolescent atopic dermatitis, successful initiation of remission was achieved through hospitalization, disease education, skincare guidance, and the combined use of appropriate topical therapy and short-term oral JAK inhibitors during the remission induction phase.

Introduction: Similar to other countries, in Japan, the demand for primary care pediatricians has increased due to the surge in pediatric allergic diseases, and with the change in a paradigm shift regarding the prevention of pediatric allergic disease in the last 20 years, they have had an increased need for retraining. To offer better support to children and their caregivers, educational needs for bridging the gap between knowledge and practice must be met. Therefore, we developed an educational program including practical and interactive approaches for pediatricians in 2012.

Article Synopsis
  • The study explores how regional factors affect participation in cardiac rehabilitation (CR) and includes a large cohort of 2.7 million inpatients in Japan from 2012 to 2021.
  • It categorizes hospitals into No-CR, High-CR, and Low-CR based on participation rates, finding that High-CR hospitals tend to have smaller service areas, more physicians per population, higher temperatures, and fewer primary industry workers.
  • Key regional characteristics influencing High-CR hospitals include a lower consumer price index and a tendency for a younger population, thus highlighting the importance of local economic and demographic factors in CR participation.

Terbinafine, fluconazole, and amorolfine inhibit fungal ergosterol synthesis by acting on their target enzymes at different steps in the synthetic pathway, causing the accumulation of various intermediates. We found that the effects of these three in- hibitors on yeast morphology were different. The number of morphological parameters commonly altered by these drugs was only approximately 6% of the total.

Quantitative morphological phenotyping (QMP) is an image-based method used to capture morphological features at both the cellular and population level. Its interdisciplinary nature, spanning from data collection to result analysis and interpretation, can lead to uncertainties, particularly among those new to this actively growing field. High analytical specificity for a typical QMP is achieved through sophisticated approaches that can leverage subtle cellular morphological changes.
