Oxy-hydroxides represent potential proton carriers for solid acid catalysts and proton conductors owing to their hydroxide-rich compositions. However, their applications in high-temperature environments are limited due to thermal instability associated with dehydration at moderate to high temperatures. Therefore, the development of oxy-hydroxides with enhanced thermal stability is of critical importance.

Methods And Results: In patients with inflammatory bowel disease treated at our hospital, the Th1/Th2 ratio (interferon-γ/interleukin-4 ratio), serum immunoglobulin E level, leucine-rich alpha 2 glycoprotein level, serum amyloid A level, and leukocyte fraction were measured simultaneously, and the relationship between them was examined.

The catalytic reduction of CO into value-added chemicals has become important in recent years, and a catalyst that is efficient, nontoxic, and inexpensive is highly demanded. In particular, room still exists for exploring mixed-anion compounds as new catalysts. Here, we show that the Zn-based mixed-anion compounds Zn(OH)(NO) and Zn(OH)(NO), which were formed on the surface of AlO using Zn(NO)·6HO as the precursor, can convert CO into HCOOH with >80% selectivity in the presence of a Ru(II) photosensitizer and 1-benzyl-1,4-dihydro-nicotinamide as an electron donor under visible light ( = 460 nm).

Design: Cross-sectional questionnaire-based survey.
Setting: Dental clinics throughout Japan.
End-of-life decision making regarding invasive mechanical ventilation (IMV) for patients with severe coronavirus disease (COVID-19) is challenging. We aimed to explore the factors associated with the withholding of IMV in patients with COVID-19. This retrospective study included patients registered in a nationwide COVID-19 Registry Japan.

Adults' behaviours in engaging with healthcare for themselves, especially when attending appointments with a child with a respiratory tract infection for whom they provide care, may contribute to the gender differences in antimicrobial use. This study aimed to evaluate gender differences in caregivers' attendance at healthcare visits for children with respiratory tract infections, their behaviours in engaging with healthcare for themselves and their children, and associated antibiotic prescriptions.

Significant correlations were observed between the clinical activity index, Mayo endoscopic subscore (MES), and each biomarker. Among MES groups, fecal biomarkers demonstrated significant differences, except between MES 2 and MES 3.

Interleukin-17 (IL-17) has been suggested to have a protective effect on the intestinal mucosa. The administration of an anti-IL-17 receptor monoclonal antibody has been associated with the onset of inflammatory bowel disease. We present a case of ulcerative colitis caused by secukinumab, an anti-IL-17 receptor A monoclonal antibody, that was treated with mirikizumab, a p19-directed antibody against IL-23.

This study aimed to investigate the utility of a new urinary biomarker, prostaglandin E-major urinary metabolite (PGE-MUM), in assessing CD activity.
Methods: The study involved 87 patients with CD who underwent endoscopic examination and measurements of 4 biomarkers: Prostaglandin E-major urinary metabolite, fecal calprotectin (FC), leucine-rich α2 glycoprotein (LRG), and C-reactive protein (CRP).
Fecal calprotectin (FC) is a Crohn's disease (CD) biomarker, although the impact of disease duration on its accuracy remains unclear. This study was aimed at investigating the effects of CD disease duration on FC. In this prospective, single-center, cross-sectional study, we performed 113 endoscopies and biomarker measurements.

Methods: Changes in the clinical activity index (CAI), blood test results, and the factors affecting VDZ rate and continuity were investigated.
Background: We examined the association between the COVID-19-specific prefectural bed utilization rate and in-hospital mortality during the first three years of the pandemic in Japan.
Methods: This nationwide study included 58,175 COVID-19 patients from the COVID-19 Registry Japan, hospitalized between May 1, 2020 and November 30, 2022. Based on the weekly COVID-19-specific bed utilization rate in each prefecture at diagnosis, patients were categorized into four groups (< 25%, 25% to < 50%, 50% to < 75%, and ≥ 75%).
Introduction: Horse kicks are a rare cause of injury and tend to cause severe complications such as visceral organ injury. Traumatic duodenal injuries are associated with high mortality rates. Furthermore, their reconstructive procedures vary widely and require appropriate on-the-spot judgment by the surgeon.

To elucidate their molecular epidemiology and clinical outcomes in Japan, patients with CRGNB were enrolled in the MDR organisms clinical research network (MDRnet) consisting of eight tertiary care facilities.
Methods: Between 2019 and 2022, 246 unique patients with carbapenem-resistant (CRE), carbapenem-resistant (CRPA) and carbapenem-resistant (CRAB) isolates were prospectively enrolled.

This study affords mechanistic insights into the formation mechanism of carbodiimide ions (NCN) from urea during the synthesis of LaONCN by employing the "proanion" strategy without using NH gas. It is a safer, cost-effective, and environmentally friendly approach. Urea, acting as a proanion, decomposes upon heating, facilitating conversion to NCN.
