Background/Aims:
Visualization of palisade vessels (PVs) in Barrett’s esophagus is crucial for proper assessment. This study aimed to determine whether red dichromatic imaging (RDI) improves PV visibility compared with white-light imaging (WLI) and narrow-band imaging (NBI).
Methods:
Five expert and trainee endoscopists evaluated the PV visibility in Barrett’s esophagus using WLI, NBI, and RDI on 66 images from 22 patients. Visibility was rated on a 4-point scale: 4, excellent; 3, good; 2, fair; and 1, poor. The color difference between the most recognizable PV spots and surrounding areas with undetectable blood vessels was also analyzed.
Results:
Mean visibility scores were 2.6±0.7, 2.3±0.6, and 3.4±0.4 for WLI, NBI, and RDI, respectively. The RDI scores were significantly higher than the WLI (p<0.001) and NBI (p<0.001) scores. These differences were recognized by trainees and expert endoscopists. Color differences in PVs were 7.74±4.96 (WLI), 10.43±5.09 (NBI), and 15.1±6.54 (RDI). The difference in RDI was significantly higher than that in WLI (p<0.001) and NBI (p=0.006).
Conclusions
RDI significantly improved PV visibility compared to WLI and NBI based on objective and subjective measures.

Background/Aims:
Metabolic dysfunction-associated steatotic liver disease (MASLD) was recently proposed as an alternative disease concept to nonalcoholic fatty liver disease (NAFLD). We aimed to investigate the prognosis of patients with biopsy-confirmed MASLD using data from a multicenter study.
Methods:
This was a sub-analysis of the Clinical Outcome Nonalcoholic Fatty Liver Disease (CLIONE) study that included 1,398 patients with NAFLD. Liver biopsy specimens were pathologically diagnosed and histologically scored using the NASH Clinical Research Network system, the FLIP algorithm, and the SAF score. Patients who met at least one cardiometabolic criterion were diagnosed with MASLD.
Results:
Approximately 99% of cases (n=1,381) were classified as MASLD. Patients with no cardiometabolic risk (n=17) had a significantly lower BMI than patients with MASLD (20.9 kg/m2 vs. 28.0 kg/m2, P<0.001), in addition to significantly lower levels of inflammation, ballooning, NAFLD activity score, and fibrosis stage based on liver histology. These 17 patients had a median follow-up of 5.9 years, equivalent to 115 person-years, with no deaths, liver-related events, cardiovascular events, or extrahepatic cancers. The results showed that the prognosis for pure MASLD was similar to that for the original CLIONE cohort, with 47 deaths and one patient who underwent orthotopic liver transplantation. The leading cause of death was extrahepatic cancer (n=10), while the leading causes of liver-related death were liver failure (n=9), hepatocellular carcinoma (n=8), and cholangiocarcinoma (n=4).
Conclusions
Approximately 99% of NAFLD cases were considered MASLD based on the 2023 liver disease nomenclature. The NAFLD-only group, which is not encompassed by MASLD, had a relatively mild histopathologic severity and a favorable prognosis. Consequently, the prognosis of MASLD is similar to that previously reported for NAFLD.

Background:
Elderly patients with femoral neck fractures, particularly those with severe comorbidities or living in regions with limited medical resources, may experience delays in surgical treatment. Although the benefits of preoperative rehabilitation (prehabilitation) in hip arthroplasty have been reported, pain management remains a challenge. The pericapsular nerve group (PENG) block, known for its exceptional analgesic effect and motor function preservation, may be a promising intervention during prehabilitation in these patients. Case: We enrolled ten patients with Garden classification 3–4 femoral neck fractures scheduled for hip arthroplasty. After receiving a PENG block with 20 ml of 0.375% ropivacaine, all patients underwent initial prehabilitation sessions comprising 9 mobility levels, ranging from bed-sitting to walking. One patient was excluded due to experiencing high blood pressure during prehabilitation. Six of the nine remaining patients (66.7%) were successfully transferred from bed to wheelchair.
Conclusions
The PENG block enhanced prehabilitation for patients with femoral neck fractures undergoing hip arthroplasty.

To improve the quality of palliative care in the Kyoto region, we thought that closely connecting hospice and palliative care units (PCU) is necessary. Subsequently, we established the Kyoto PCU Liaison Committee in September 2017. This committee was created as a place to casually discuss the problems that individual PCU facilities have, deliberate on their worries together, grow and develop, and support newly launched facilities. Furthermore, discussions were held on current topics (emergency hospitalization, blood transfusion, smoking, bereaved family meetings, etc.) at the liaison meetings. While meetings were adjourned in 2020 due to the COVID-19 pandemic, we continued to exchange opinions on infection control, PCU management, etc., using the email network at first. Later, these meetings resumed via web conference systems. Thus, by having face-to-face relationships on a daily basis, we were able to maintain cooperation between PCUs even during the pandemic, and collaborate with cancer treatment hospitals. Overall, by forming a team of PCUs in Kyoto Prefecture, we aim to enable patients and their families to live with peace of mind wherever they are.

Prophylaxis is sometimes offered to inpatients who share a room with, or individuals who have been in close contact with, patients who have contracted influenza. In our hospital, 5-day prophylactic oseltamivir has been used as a standard procedure. Here, we investigated the effectiveness of this post-exposure prophylaxis for inpatients and healthcare professionals, as well as its effect on hospital management. The study period was 5 years from fiscal year 2013 to fiscal year 2017, and the effectiveness outcome was the secondary infection rate. Medication costs for this prophylaxis were compared with those for oseltamivir used according to the package insert. The secondary infection rates were 3.0% and 0.5% in 133 inpatients and 434 healthcare professionals who had received post-exposure oseltamivir, respectively. The medication costs were reduced by 50% compared with the estimated costs for 10-day oseltamivir administration. The effectiveness of 5-day prophylactic oseltamivir was similar to or higher than that reported previously, indicating that this prophylaxis was effective. Moreover, 5-day post-exposure prophylactic oseltamivir is expected to reduce the prolongation of hospital stay and influenza outbreaks and thus contribute to hospital management.

BACKGROUND:
Studies on the adverse effects of Asian dust (AD) on respiratory function in children are scarce. The objective of this study was to examine the association between AD and respiratory function by measuring peak expiratory flow rates (PEFRs) in asthmatic children.
METHODS:
The study was carried out from March to May from 2014 through 2016. One hundred ten children with bronchial asthma were recruited from four hospitals in the Goto Islands and south Nagasaki area in Nagasaki prefecture. The parents were asked to record their children's PEFRs every morning/evening and clinical symptoms in an asthma diary. AD was assessed from light detection and ranging data, and a linear mixed-effects model was used to estimate the effects of AD on daily PEFR. Time-stratified case-crossover analyses were performed to examine the association between AD and asthma attacks defined by reduction levels in PEFR.
RESULTS:
AD was detected on 11 days in the Goto Islands, and on 23 days in the south Nagasaki area. After adjusting for age, sex, temperature, and daily oxidants, we found a consistent association between AD and a 1.1% to 1.7% decrease in PEFR in the mornings and a 0.7% to 1.3% decrease in the evenings at a lag of 0 to 5 days. AD was not associated with the number of asthma attacks, respiratory symptoms, or other symptoms at any lag days examined.
CONCLUSIONS
Exposure to AD was associated with reduced PEFR, although the effects were not large enough to induce clinically apparent symptoms, in clinically well-controlled asthmatic children.

In Kampo medicine, a tongue examination, whereby the shape and color of the tongue is observed, is thought to reveal the constitution and condition of the patient. In Japan, numerous books on this tongue examination have been published. However, tongue findings are expressed differently in these books, and a standard description for such findings has yet to be established. A standard description would be useful when examining the tongue, and when educating students of Kampo medicine. We therefore compared how tongue colors and shapes were expressed in the Japanese literature on tongue examinations (12 publications).
Using these results, we have arrived at a standardized description for tongue findings in accordance with Kampo specialists of tongue diagnoses at many facilities. In the process, we focused on easily recognizable findings that can be noted with short clinical examination times, and that can also be understood by beginners.
