Purpose: The proportion of terminally ill cancer patients who were discharged home from a hospice/palliative care unit and subsequently died either at home or in the palliative care unit, whose final place of death was consistent with their intended place of care, remains unclear. This study aimed to clarify the consistency between the preferred and actual place of death. Methods: This study was a supplementary study to a multi-institutional bereavement survey conducted in 2018. Results: Responses were obtained from the bereaved families of 202 patients who died at home and 157 patients who died in a palliative care unit. Among them, 80% of home deaths and 82% of palliative care unit deaths were consistent with the stated end-of-life care preference. Among the 22 cases who preferred to die in a palliative care unit but died at home, the most common reason was the availability of physicians and nurses who could provide end-of-life care at home. Among the 11 cases who preferred to die at home but the patients died in a palliative care unit, the most common reason was insufficient pain management at home. Conclusion: Approximately 80% of patients died by their end-of-life care preference, suggesting that many were able to die in their preferred location.

Tumor necrosis factor receptor-associated factor 3 (TRAF3) is an anti-inflammatory molecule that negatively regulates the non-canonical nuclear factor-κB pathway. Although TRAF3 haploinsufficiency (TRAF3 HI) can influence innate and adaptive immune cells, its effect on inflammatory bowel disease (IBD) development remains unclear. Here, we report the first case of severe early-onset IBD with a novel TRAF3 variant leading to HI, successfully treated with ustekinumab. A 6-year-old girl with a recurrent parotitis, otitis media, tonsilitis, and atopic dermatitis developed IBD involving the stomach, small intestine, and colon. At diagnosis, the immunoglobulin (Ig)G and IgA levels were relatively high, and lymphocyte subsets showed increased counts of plasmablasts, class-switch recombination B cells, and circulating T-follicular helper cells. Treatment with azathioprine and infliximab failed to maintain remission marked by several relapses accompanied by erythema nodosum and arthritis; however, ustekinumab, an anti-interleukin (IL)-12/23p40 antibody, led to long-term clinical remission, normalizing the Ig level and reducing abnormal lymphocyte counts. Whole-exome sequencing revealed a novel heterozygous mutation in TRAF3 [p.(Pro487Leufs*8)], resulting in TRAF3 under-expression. Our case may highlight the contribution of TRAF3 HI to the development of IBD and provide insights into IBD pathophysiology, suggesting the involvement of the IL-12/23-T-follicular helper cell pathway affected by genetic mutations.

The nasal mucosa and submucosa likely contain both vascular beds against cold and dry air and resident immunoreactive cells against various antigens. Therefore, a specific fibrous structure seems to be necessary. Using histological specimens from 20 elderly cadavers, we examined the nasal mucosal and submucosal architecture. The ciliated columnar epithelium of the nasal mucosa was characterized by 1) a thick basal lamina, 2) few elastin-positive fibers beneath the epithelium, that was quite different from the nearby mucocutaneous junction area with a thick layer (0.3–0.8 mm) of elastic and oxytalan fibers corresponding to the skin dermis, 3) CD34-positive cells distributing diffusely in the submucosal tissue, and 4) few smooth muscle actin (SMA)-positive fibers beneath the epithelium. Some of submucosal fibrous structure appeared to express both elastin and CD34. CD34-positive arterioles were abundant beneath the ciliated epithelium, but they appeared negative for SMA antibody that cross-reacts with endothelium. Notably, the ciliated columnar epithelium was thin in the lateral wall of the nasal cavity, while the inferior concha carried the thick pseudostratified columnar epithelium.Strangely, the inferior or palatal wall of the nasal cavity was covered by the thick stratified epithelium. We found SMApositive mucosal venous plexus in the lateral wall of nasal cavity, but the submucosa was filled with glands in the inferior concha. Vascular beds might be replaced by glands in the nasal submucosa. The site-dependent difference in the mucosal morphology as well as the absence of vascular beds might be a result of secondary change with aging.

Background:
Identifying dysmorphic red blood cells (RBCs) is critical for diagnosing glomerular diseases, as distinguishing glomerular from non-glomerular hematuria may reduce reliance on invasive diagnostics such as kidney biopsy. We aimed to enhance urinary RBC morphological classification by employing machine learning (ML) to analyze UF-5000 scattergram data.
Methods:
RBCs in urine samples (N = 185) were classified as dysmorphic or isomorphic based on microscopic findings. UF-5000 scattergrams were quantified to generate 20 statistical features and used to train a ML model in DataRobot (v9.1) with an automated pipeline, five-fold cross-validation, and LogLoss-based selection. Performance was evaluated in an independent cohort (N = 1,093). Accuracy was defined as concordance with microscopy findings. Areas under ROC curves (AUROCs) and diagnostic metrics are reported with 95% confidence intervals (CIs).
Results:
Among conventional UF-5000 parameters, the small RBC/total RBC ratio was the strongest predictor (AUROC 0.97, 95% CI 0.94–0.99). Scattergram-derived features indicated that RBC size-related parameters were crucial for identifying dysmorphic RBCs. The ML model alone demonstrated superior accuracy over UF-5000 RBC-Info alone (concordance 95.2% vs. 92.1%; AUROC 0.95 [0.94–0.97] vs. 0.92 [0.91–0.94]). Logical (OR/ AND) combinations of the ML model with RBC-Info outperformed RBC-Info alone (OR: concordance 92.7%, AUROC 0.93 [0.92–0.95]; AND: concordance 94.6%, AUROC 0.94 [0.93–0.96]).
Conclusions
A scattergram-based ML model improves the accuracy and reliability of urinary RBC morphological classification based on UF-5000 scattergrams and may help reduce reliance on invasive diagnostics. Prospective, multicenter studies should validate generalizability and assess integration into routine workflows.

Introduction: We aimed to evaluate the impact of lifestyle modifications on the risk of eradication failure in patients undergoing first-line therapy for Helicobacter pylori infection.Methods: A survey was conducted in a community pharmacy to assess changes in alcohol consumption, smoking, and high-fat diet intake before, during, and after first-line therapy for H. pylori infection in enrolled patients.Results: A total of 100 patients (response rate: 3.4%) were included in the analysis. Before therapy, 20 patients (20%) smoked, 35 patients (35%) consumed alcohol, and 91 patients (91%) had a high-fat diet. During therapy, the proportion of patients who changed their habits was 15.0% (3/20) for smoking, 71.4% (25/35) for alcohol consumption, and 28.6% (26/91) for high-fat diet. However, the continuation of these changes post-therapy was minimal.Conclusion: Among patients undergoing first-line therapy for H. pylori infection, lifestyle habits that increase the risk of eradication failure were prevalent, with many patients maintaining their habits during therapy except for alcohol consumption. These findings provide fundamental data for lifestyle counselling during eradication therapy.

A 73-year-old man, who underwent total esophagectomy and gastric tube reconstruction via the retrosternal route for esophageal cancer 10 years eariler, was referred to our hospital with chest pain. He was suspected of acute coronary syndrome, and coronary artery angiography was performed, showing in-stent restenosis of the proximal site of the right coronary artery, diagnosed as the culprit lesion, and drug-coated ballooning was performed. His symptoms improved, however, the poor expansion of the stent and in-stent stenosis remained, and he was referred to our department for coronary artery bypass surgery. Because the gastric tube was reconstructed just below the sternum and performing sternotomy seemed to be difficult, a left mini-thoracotomy approach using great saphenous vein was planned. Under general anesthesia, an approximately 10-cm skin incision was made on the left fifth rib from the anterior axillary to the midclavicular line, and the chest wall was opened at the fifth and third intercostal spaces from the same skin incision, to secure views of the AV node branch and ascending aorta. First, the great saphenous vein was anastomosed to the ascending aorta from the third intercostal space, using 3.8 mm puncher and Heartstring III (Getinge, Lindholmspiren, Sweden). After that, the graft was guided extrapericardially via the left intrathoracic cavity, and was anastomosed to the AV nodal branch from the fifth intercostal space. The graft blood flow was 48 ml/min. The postoperative course was uneventful and contrast-enhanced CT confirmed the patency of the graft.

A 33-year-old female was admitted to the intensive care unit (ICU) due to respiratory failure. During her ICU stay, she developed multiple organ failure and neuropsychiatric symptoms, and was diagnosed with neuropsychiatric systemic lupus erythematosus (NPSLE). The patient faced difficulties in activities of daily living (ADL) recovery due to severe psychiatric symptoms and generalized muscle weakness; however, after one year of rehabilitation intervention, she achieved independence in ADL. NPSLE may occur more common in cases with high disease activity. Therefore, it is essential to consider the neuropsychiatric symptoms and implement rehabilitation interventions accordingly among critically ill patients with SLE. Additionally, as physical function improves following psychiatric symptom improved, rehabilitation intervention should aim for ADL recovery with disease activity and neuropsychiatric symptoms as indicators.

Purpose: In this case report, we examined the effects of an aquatic exercise program on respiratory and knee extensor muscle strength in a 72-year-old female patient with knee osteoarthritis and reduced respiratory muscle strength. Decreased respiratory muscle strength is linked to a diminished coughing capacity, which increases the risk of atelectasis and pneumonia, particularly in older individuals with limited physical activity. This study reports the effects of aquatic exercise on a patient with knee osteoarthritis and decreased respiratory muscle strength. Methods: The patient participated in an 8-week aquatic exercise regimen, including walking in water at a depth above the fourth intercostal level, to achieve 60% of the predicted maximum heart rate. The pre- and post-intervention measurements included knee extension strength, grip strength, respiratory muscle pressure, vital capacity, and 6-meter walking speed. Results: Improvements in expiratory muscle strength, bilateral knee extension strength, and walking speed were observed after the intervention. Conclusions: Buoyancy of the aquatic environment minimizes joint load, whereas water viscosity provides resistance and enhances muscle strength without adverse effects. The increase in expiratory muscle strength suggests a potential training effect on the respiratory muscles owing to hydrostatic pressure resistance. These findings underscore the value of aquatic exercise in patients with musculoskeletal limitations and suggest its utility in maintaining respiratory function in older populations. Future research should explore long-term effects and include broader sample sizes to validate these outcomes.

Objective:
This multicenter study aimed to evaluate the impact of paravertebral muscles (PVMs) degeneration, particularly fat infiltration, on preoperative sagittal imbalance, and postoperative complications and sagittal alignment change in patients with adult spinal deformity (ASD).
Methods:
A retrospective analysis was conducted on 454 patients who underwent ASD surgery across 5 institutions. Patients were classified into 2 groups based on paraspinal muscle fat infiltration on MRI: those with significant infiltration (FI-PVM(+)) and those with minimal or no infiltration (FI-PVM(-)). Propensity score matching was performed to adjust for demographic factors and preoperative radiographical parameters. Spinopelvic parameters were assessed preoperatively, postoperatively, and at a 2-year follow-up. Mechanical complications were compared between the groups.
Results:
The FI-PVM(+) group showed greater sagittal vertical axis (86.4 ± 57.5 vs. 51.8 ± 59.2, p < 0.001) preoperatively and required more extensive surgical correction with a significantly greater number of fused vertebral levels (7.3 ± 3.7 vs. 6.7 ± 3.7, p < 0.039). After propensity score matching, both groups showed significant improvement in spinopelvic alignment postoperatively, maintained throughout the 2-year follow-up. However, the FI-PVM(+) group demonstrated a trend toward a higher incidence of distal junctional kyphosis (6.3% vs. 0.9%, p = 0.070) and exhibited significantly greater decrease in pelvic tilt postoperatively (4.3° ± 7.6° vs. 1.3° ± 8.2°, p = 0.006).
Conclusion
Fat infiltration in PVM is associated with increased surgical complexity and a higher risk of mechanical complications. Preoperative assessment of muscle quality, along with targeted rehabilitation and closer postoperative monitoring, may be crucial for improving long-term outcomes in ASD surgery.
