Correlation between geriatric nutritional risk index and oral condition in gastric cancer patients.

OBJECTIVES: Nutritional status is a useful prognostic factor in gastric cancer patients. Since oral hypofunction may cause undernutrition, we cross-sectionally investigated whether the Geriatric Nutritional Risk Index (GNRI) is affected by the number of remaining teeth, occlusal support status and denture use. MATERIALS AND METHODS: The participants were 114 patients diagnosed with gastric cancer between April 2017 and March 2020. The stage of gastric cancer, body mass index, albumin level, total lymphocyte count, C-reactive protein level and GNRI were evaluated. The number of remaining teeth was also evaluated, and the occlusion state was determined based on the Eichner classification. The patients were divided into three main groups representing different occlusal states based on the Eichner index and were also categorised based on denture use. RESULTS: The mean age ± standard deviation of the patients was 75.2 ± 5.5 years. The Eichner classification had a significant positive correlation with GNRI. Low GNRI was associated with a poor occlusal state in group C, while a higher GNRI was associated with a stable occlusal state in group A. However, the denture-related groups showed no significant differences in GNRI. CONCLUSION: The GNRI was associated with the occlusal support level but not with denture use.

Association between oral function and nutrition in gastric cancer patients undergoing chemotherapy.

OBJECTIVES: This study aimed to clarify the relationship between the oral assessment guide (OAG), a simple method for assessing oral function and poor nutrition in gastric cancer patients and investigate the reduction of oral mucositis through appropriate oral function management. SUBJECTS AND METHODS: Gastric cancer patients who underwent chemotherapy at the Nagoya Ekisaikai Hospital between January 2015 and December 2020 were evaluated. The prognostic nutritional index (PNI), as the objective variable, was used to assess nutritional status. The explanatory variables were sex, age, smoking status, body mass index (BMI), number of remaining teeth, cancer stage, albumin level, C-reactive protein level, white blood cell count and the OAG score. RESULTS: PNI was significantly associated with age, number of remaining teeth, cancer stage and the OAG score (p < 0.05) among the 217 patients. There were significant differences in age, BMI, cancer stage and the OAG score among the patients. An abnormal BMI and an advanced cancer stage were more common in older patients, and abnormal OAG scores were associated with a lower PNI. CONCLUSIONS: For gastric cancer patients undergoing postoperative chemotherapy, worse oral functional status is associated with worse PNI and nutritional status.

Factors associated with a reduced food intake after third molar extraction among adults: a cross-sectional study.

BACKGROUND: Functional impairment after third molar extraction may decrease the food intake. Elucidation of associated factors will contribute to a more appropriate postoperative nutritional management, and was the aim of the present study. METHODS: Adults aged < 60 years who were admitted for an extraction of one or more mandibular third molars were included. Those with diabetes mellitus, anemia, metabolic diseases, mental retardation, altered dietary intake, and postoperative paralysis of the lower lip and tongue were excluded. Patient-specific risk factors were compared in relation to a decrease in the food intake on postoperative day 1. Multivariate analysis took into account the patients' background factors. RESULTS: A total of 254 patients were included (median age: 26.8 ± 9.3 years, 142 women); 508 third molars were extracted. Postoperative dietary intake reduction was more common (p < 0.05) after an exclusively mandibular extraction (16.0%) than after an extraction including the maxilla (29.4%). The reduction was also more common (p < 0.05) for an extraction difficulty of Pell-Gregory class III (39.5%) than for extraction difficulties of Pell-Gregory classes I (22.6%) and II (21.3%). The reduction was also more common (p < 0.05) in patients who experienced postoperative pain (66.7%) than in those who did not (23.3%). Significant differences were observed in sex (women: 34.5%, men: 11.6%) and age (young patients [< 26 years]: 31.1%, adult patients [≥ 26 years]: 17.2%); however, no significant difference was found in terms of experiencing trismus (p < 0.11). Simple regression analysis showed significant differences between patients who did and did not have a reduced postoperative food intake depending on the sex, age, extraction site, degree of extraction difficulty, trismus, and postoperative pain. Reduced dietary intake was significantly associated with sex (odds ratio [OR]: 0.30; 95% confidence interval [CI]: 0.14-0.38), age (OR: 1.6; 95% CI: 1.0-2.5), extraction site (OR: 0.51; 95% CI: 0.31-0.83), difficulty of extraction (OR: 0.66; 95% CI: 0.50-0.88), and postoperative pain (OR: 0.12; 95% CI: 0.04-0.37). CONCLUSIONS: A younger age, female sex, extraction including the maxilla with deep implantation, and complaints of pain on postoperative day 1 were factors associated with a decreased food intake after third molar extraction.

Low-Background Tip-Enhanced Raman Spectroscopy Enabled by a Plasmon Thin-Film Waveguide Probe.

Tip-enhanced Raman spectroscopy (TERS) is a nano-optical approach to extract spatially resolved chemical information with nanometer precision. However, in the case of direct-illumination TERS, which is often employed in commercial TERS instruments, strong fluorescence or far-field Raman signals from the illuminated areas may be excited as a background. They may overwhelm the near-field TERS signal and dramatically decrease the near-field to far-field signal contrast of TERS spectra. It is still challenging for TERS to study the surface of fluorescent materials or a bulk sample that cannot be placed on an Au/Ag substrate. In this study, we developed an indirect-illumination TERS probe that allows a laser to be focused on a flat interface of a thin-film waveguide located far away from the region generating the TERS signal. Surface plasmon polaritons are generated stably on the waveguide and eventually accumulated at the tip apex, thereby producing a spatially and energetically confined hotspot to ensure stable and high-resolution TERS measurements with a low background. With this thin-film waveguide probe, TERS spectra with obvious contrast from a diamond plate can be acquired. Furthermore, the TERS technique based on this probe exhibits excellent TERS signal stability, a long lifetime, and good spatial resolution. This technique is expected to have commercial potential and enable further popularization and development of TERS technology as a powerful analytical method.

Glucose Monitoring in Cell Culture with Online Ultrasound-Assisted Near-Infrared Spectroscopy.

Near-infrared (NIR) spectroscopic analysis for suspensions often requires a pretreatment by dilution or filtering of suspended solids to maintain the sensitivity of the measurements. An online ultrasound-assisted spectroscopy (UAS) unit enabling pretreatment-free and noncontact analysis for bioprocessing is proposed and evaluated with a model suspension containing 3-µm-diameter polystyrene latex particles (PSLs) with the density of 5.1 × 108 counts/ml and Chinese hamster ovary (CHO) cell culture whose cell density was 3.2 × 107 cells/ml. The online UAS uses acoustic radiation force generated by ultrasonic standing waves. Suspended matter such as the PSLs and CHO cells can be localized at nodal planes in the suspensions by the acoustic radiation force. Hence, in the case of the online UAS, incoming light can pass through the suspensions more easily than that in the case of a conventional spectroscopy. Its effectiveness was evaluated by the predictive capability of a calibration model for glucose concentrations in the model suspensions and the CHO cell cultures. The calibration models were constructed by use of a partial least-squares regression (PLS-R) in the range of 4900-4200 cm-1 region after the pretreatment of second-order Savitzky-Golay filter. The calibration model built from the NIR spectra acquired with the online UAS could predict the glucose concentration in the CHO cell cultures with a measurement error of 0.6%. It was validated that the glucose concentrations in the flowing model suspension were able to be monitored by the online UAS with a measurement error of 8%. The newly developed online UAS for cell culture monitoring allows us to promote a wider use of NIR spectroscopy. For example, in the applications to the biopharmaceutical and cell-therapy industries, the online UAS enables simpler and easier monitoring of cell cultures because cleaning and sterilization of monitoring tools after cell culturing can be eliminated.

Low signal intensities of MRI T1 mapping predict refractory diplopia in Graves' ophthalmopathy.

OBJECTIVE: In Graves' ophthalmopathy (GO), fibrosis in extraocular muscles (EOMs) may be related to intravenous glucocorticoid (ivGC)-resistant diplopia. Signal intensity (SI) of magnetic resonance imaging (MRI) T1 mapping can quantify properties of EOM components, including fibrosis. We investigated EOM features of GO patients with diplopia using T1 mapping SI and the predictive value of T1 mapping SI in the response of diplopia to ivGCs. DESIGN: We performed a cross-sectional study that included 13 active GO patients, 34 inactive GO patients with history of diplopia, including 20 with a history of diplopia disappearance, 14 GO patients with refractory diplopia and 35 control subjects. In nine active GO patients, the relationship between T1 mapping SI at pretreatment and at diplopia outcome after ivGC treatment was prospectively investigated. METHODS: T1 mapping SI of left and right inferior rectus and medial rectus muscles was measured in all participants. RESULTS: T1 mapping SI in inactive GO patients with refractory diplopia was significantly lower than that of other groups in all evaluated EOMs. Diagnostic accuracy for refractory diplopia by T1 mapping SI in GO patients with a history of diplopia disappearance was excellent (AUC 0.89) compared with other assessments. Furthermore, among nine active GO patients, pretreatment T1 mapping SI in four patients with ivGC-resistant diplopia tended to be low compared with the other five patients with improved diplopia. CONCLUSIONS: Low intensity T1 mapping in EOMs is likely to be associated with refractory diplopia and may be useful in predicting the response of diplopia to ivGCs.

Generation of broadband near-field optical spots using a thin-film silicon waveguide with gradually changing thickness.

We developed a thin-film silicon waveguide with gradually changing thickness for generating a near-field optical spot. Theoretical studies show that the surface plasmons that are resonantly excited on the waveguide generate a hot spot with a wide spectral range. We experimentally confirmed generation of the near-field hot spot using continuous waves at 850 and 660 nm wavelengths. This waveguide, which can generate the enhanced electric field by normal incident of the excitation beam under situations of the practical use, is promising for broadband near-field optical technologies.

Implications of FoxP3-positive and -negative CD4(+) CD25(+) T cells in Graves' ophthalmopathy.

Graves' ophthalmopathy (GO) is a common manifestation of Graves' disease (GD); however, its pathogenesis is not well understood. Recently, the dysregulation of regulatory T cells (Tregs) has been thought to be closely associated with the pathogenesis and clinical symptoms of autoimmune disease. We therefore evaluated whether T cell subsets, including Tregs, are associated with GO pathogenesis and clinical symptoms. In this observational study we evaluated 35 GD patients with overt ophthalmopathy (GOs) and 28 patients without ophthalmopathy (non-GOs). Fifteen healthy euthyroid patients served as healthy controls (HCs). Peripheral blood mononuclear cells from GOs, non-GOs and HCs were analyzed for CD4, CD25, and FoxP3 expression using flow cytometry. We also evaluated their correlation with disease activity according to the clinical activity score (CAS) and magnetic resonance imaging (MRI) findings. Disease severity was evaluated using the NOSPECS score, and clinical progression of GO was followed for 24 weeks. The main outcome measures were the frequencies of FoxP3-positive and -negative CD4(+) CD25(+) T cells at study outset, namely Tregs and effector T cells (Teffs), respectively. GOs had higher frequencies of Teffs (30.8±8.4%) than non-GOs (19.4±7.1%) and HCs (22.7±7.9%). Notably, patients with improved GOs had lower frequencies of Tregs (5.8±1.1%) than patients with stable or deteriorated GOs (7.3±1.2%), although ophthalmic and radiological parameters were not significantly different at the start of the study. In conclusion, an expanded Teff population may be associated with GO pathogenesis. Additionally, decreased Tregs in peripheral blood may predict a good clinical outcome.

Association between serum soluble low-density lipoprotein receptor levels and metabolic factors in healthy Japanese individuals.

BACKGROUND: Soluble low-density lipoprotein receptor (sLDL-R) is formed by cleavage of the extracellular domain of low-density lipoprotein receptor (LDL-R). It is unclear whether serum sLDL-R is a marker of diseases associated with triglyceride (TG) metabolism. We investigated the association between serum sLDL-R concentrations and other biochemical parameters in healthy Japanese individuals. METHODS: Study subjects consisted of 102 healthy adult Japanese volunteers (42 men, 60 women) with body mass index (BMI) < 30 kg/m(2) and serum TGs, LDL cholesterol (LDL-C), aspartate aminotransferase, alanine aminotransferase, γ-glutamyl transpeptidase, and glucose concentrations within normal ranges. Serum sLDL-R concentrations were determined by enzyme-linked immunosorbent assay and their correlations with biochemical parameters were analyzed. RESULTS: Mean serum sLDL-R concentration was 120.9 ± 39.9 ng/ml. Serum sLDL-R levels were significantly and positively correlated with BMI (rs = 0.252) and TG (rs = 0.408) and LDL-C (rs = 0.325) concentrations. Multiple regression analysis adjusted for age, gender, and smoking showed that BMI (ß = 0.274), TG (ß = 0.328), and LDL-C (ß = 0.224) were factors independently correlated with sLDL-R levels. CONCLUSION: Serum sLDL-R concentration may be a marker of diseases associated with TG metabolism. This is the first report to date describing the clinical relevance of sLDL-R.

Implication of intracellular localization of transcriptional repressor PLZF in thyroid neoplasms.

BACKGROUND: Promyelocytic leukaemia zinc finger (PLZF) is a transcriptional repressor that was originally isolated from a patient with promyelocytic leukaemia. PLZF also affects key elements for cell cycle progression, such as cyclin A, and can affect the tumourigenicity of various cancers. Thus far, the behaviour of PLZF in thyroid carcinoma remains unclear. METHODS: We analysed the expression profile of PLZF in different types of benign and malignant thyroid lesions as well as in normal thyroid tissue. Specifically, we examined PLZF expression in normal thyroid (N; n = 4), adenomatous lesion (AL; n = 5), follicular adenoma (FA; n = 2), papillary thyroid carcinoma (PTC; n = 20), and anaplastic thyroid carcinoma (ATC; n = 3) samples. PLZF expression was estimated by western blotting and immunohistochemical (IHC) staining. RESULTS: PLZF was expressed in all samples of thyroid lesions examined. In N, AL, and FA, PLZF was mainly localized in the nucleus. In contrast, in PTC and ATC, PLZF was mainly expressed in the cytosol with high intensity. In more detail, the cytoplasmic IHC scores in PTC with capsular invasion (CI) and lymph node (LN) metastasis were higher than those in PTC without CI and LN metastasis. CONCLUSIONS: PLZF shows different subcellular localizations among PTC, ATC, and other thyroid lesions. Furthermore, high cytoplasmic expression of PLZF may be correlated with CI and LN metastasis in thyroid carcinoma. The present report is the first to describe the implications of intracellular PLZF expression in thyroid carcinomas.

A comparative study on the effectiveness of losartan/hydrochlorothiazide and telmisartan/hydrochlorothiazide in patients with hypertension.

PURPOSE: Long-term effects of a low-dose hydrochlorothiazide (HCTZ) with losartan (LOS) on uric acid (UA) metabolism as well as glucose metabolism have been studied in hypertensive patients in comparison with those of a low-dose HCTZ with telmisartan (TEL). METHOD: Fifty-nine hypertensive patients were allocated to a combination therapy with either losartan (50 mg/day)/HCTZ (12.5 mg/day) (LOS + HCTZ group: n = 37) or telmisartan (40 mg/day)/HCTZ (12.5 mg/day) (TEL + HCTZ group: n = 22), respectively. Before and 1 year after the treatment, blood pressure and biochemical parameters of blood and urine were evaluated. RESULTS: Both systolic and diastolic blood pressures significantly decreased in two groups, without any statistical differences among them. LOS + HCTZ caused no changes in the serum UA level or the ratio of UA clearance to creatinine clearance (CUA/Ccr), whereas TEL + HCTZ significantly increased the serum UA level and reduced CUA/Ccr. LOS + HCTZ did not influence CUA/Ccr in patients with their serum UA below 5.4 mg/dl, while LOS + HCTZ significantly increased CUA/Ccr in patients with their serum UA above 5.5 mg/dl. TEL + HCTZ significantly reduced CUA/Ccr in patients with their serum UA below and above 5.4 mg/dl to increase serum UA level significantly. Neither combination therapies caused any changes in fasting plasma glucose, HbA1c and HOMA-R. In patients with their serum UA level above 5.4 mg/dl, TEL + HCTZ increased HOMA-R, whereas LOS + HCTZ did not. CONCLUSIONS: LOS + HCTZ did not influence UA metabolism as well as glucose metabolism, likely because of inhibitory action of losartan on URAT1, although TEL + HCTZ were accompanied with impairment of the UA metabolism and glucose metabolism.

Autoantibody against WD repeat domain 1 is a novel serological biomarker for screening of thyroid neoplasia.

BACKGROUND: Thyroid nodules are common among adults, and accurate diagnosis is critical in for management decisions. Ultrasound and fine needle aspiration cytology are the most common methods to evaluate nodules, but they are not practical for screening large numbers of patients because of cost and time considerations. OBJECTIVE: The aim of this study was to isolate an autoantibody to tumour antigen, WD repeat domain 1 (WDR1), and evaluate its diagnostic sensitivity and specificity for thyroid neoplasms. PATIENTS AND METHODS: We investigated serological biomarkers in patients with thyroid carcinoma who had a poor prognosis. Using a serological analysis of recombinant cDNA expression cloning (SEREX) strategy, we isolated WDR1 and its specific autoantibody in the sera of patients with undifferentiated thyroid carcinoma (UTC). We examined using indirect ELISA, the titre of the anti-WDR1 antibody (AWA) in 54 study patients: 10 with UTC, 20 with papillary thyroid carcinoma (PTC), 17 with benign thyroid nodule (BTN), 7 with autoimmune thyroid disease (AITD), as well as 38 controls (N). RESULTS: WDR1 was ubiquitously expressed in various types of thyroid tissues. However, the titre of AWA in UTC and PTC was significantly higher than that in BTN, AITD and N (P < 0·001). No significant correlation was observed between thyroid function, serum thyroglobulin and tumour diameter. The cut-off value estimated using ROC to differentiate malignancies from others was 0·95 (sensitivity 96·7%, specificity 91·9%, AUC 0·969, P < 0·001). CONCLUSIONS: Anti-WDR1 antibody could be a novel approach for serological screening of PTC and UTC, and could be an efficient and inexpensive biomarker.

20/(fasting C-peptide × fasting plasma glucose) is a simple and effective index of insulin resistance in patients with type 2 diabetes mellitus: a preliminary report.

BACKGROUND: We developed a simple and new insulin resistance index derived from a glucose clamp and a meal tolerance test (MTT) in Japanese patients with type 2 diabetes mellitus. METHODS: Fifteen patients [mean age: 53 years, fasting plasma glucose (FPG) 7.7 mmol/L, HbA1c 7.1% (54 mmol/mol), body mass index 26.8 kg/m(2)] underwent a MTT and a glucose clamp. Participants were given a test meal (450 kcal). Plasma glucose and insulin were measured at 0 (fasting), 30, 60, 120, and 180 min. Serum C-peptide immunoreactivity (CPR) was measured at 0 (fasting; F-CPR) and 120 min. Homeostasis model assessment of insulin resistance (HOMA-IR) and insulin sensitivity indices (ISI) were calculated from the MTT results. The glucose infusion rate (GIR) was measured during hyperinsulinemic-euglycemic glucose clamps. RESULTS: The mean GIR in all patients was 5.8 mg·kg(-1)·min(-1). The index 20/(F-CPR × FPG) was correlated strongly with GIR (r = 0.83, P < 0.0005). HOMA-IR (r = -0.74, P < 0.005) and ISI (r = 0.66, P < 0.01) were also correlated with GIR. In 10 patients with mild insulin resistance (GIR 5.0-10.0 mg·kg(-1)·min(-1)), 20/(F-CPR × FPG) was very strongly correlated with GIR (r = 0.90, P < 0.0005), but not with HOMA-IR and ISI (r = -0.49, P = 0.15; r = 0.20, P = 0.56, respectively). In patients with mild insulin resistance, plasma adiponectin (r = 0.65, P < 0.05), but not BMI or waist circumstance, was correlated with GIR. CONCLUSIONS: 20/(F-CPR × FPG) is a simple and effective index of insulin resistance, and performs better than HOMA-IR and ISI in Japanese patients with type 2 diabetes mellitus. Our results suggest that 20/(F-CPR × FPG) is a more effective index than HOMA-IR in Japanese patients with mild insulin resistance.

Possibility of alleviating difficulties of health and social care professionals engaged in end-of-life care through Clinical Art program.

Background: Health and social care professionals experience high-stress levels during end-of-life care. Various intervention programs have been proposed to reduce stress and prevent burnout among physicians and nurses, including arts-based activities that have shown potential. However, it is unclear how art programs can alleviate stress among healthcare professionals providing end-of-life care. This study aimed to explore the potential of Clinical Art programs to alleviate distress in professionals providing end-of-life care. Methods: Two Clinical Art workshops, held in October and November 2020, were attended by local health and social care professionals. Focus groups were conducted with those who attended and consented to participate in the study. Verbatim transcripts were made, and a qualitative analysis of the text was conducted. Results: Thirteen health and social work professionals participated in the study. Perceived difficulties in end-of-life care included the complexity and uncertainty of end-of-life care services, the approaches to patients and families, and the difficulties due to human aspects of healthcare providers. The positive effects of Clinical Art included pure enjoyment of art, empathic communication with patients and families and the application of an ontological view of human beings, which were identified as reasons for Clinical Art's effectiveness and applicability to care. Conclusions: The results suggest that the Clinical Art program has a psychosocial moderating effect on health and social work professionals and can be used for empathic communication with patients and families in end-of-life care and for applying an ontological view of human beings in caring for patients.

Keep thinking about unanswered questions in primary care: Cultivating negative capability.

Negative capability or tolerance for uncertainty is important for primary care physicians. The 2022 edition of the Model Core Curriculum for Medical Education also states that the content of professionalism is to "keep thinking about unanswerable questions."

Learning and elucidating the uncertainty in primary care by mapping uncertainty in medicine.

This letter reports on a workshop aiming to ease clinical practice by mapping uncertainties in clinical practice. The workshop was indeed effective considering the mapped uncertainties based on previous research and included discussion. We believe that future expansion of similar activities will promote the study of uncertainty in clinical practice.

A Case of Weight Gain and Edema With Difficulty in Moving Legs Due to Intravascular Large B-cell Lymphoma Diagnosed by Skin Biopsy.

We report a case of intravascular large B-cell lymphoma (IVL) with spinal cord involvement. A 76-year-old woman was referred to our department due to generalized edema and weight gain. She also had difficulty moving her legs. She had no superficial lymphadenopathy upon examination. Her laboratory tests showed a markedly elevated blood lactate dehydrogenase (LDH) level. Although heart failure or interstitial lung disease was initially suspected, she was diagnosed with IVL by skin biopsy. An MRI revealed spinal cord involvement. Post-hospitalization, she began rituximab-combined chemotherapy. In this case, we considered that the spinal cord involvement of the lymphoma caused the neurogenic bladder and leg weakness. IVL often infiltrates the central nervous system and presents with neurological symptoms, including neurogenic bladder. Therefore, imaging studies should be planned to search for the involvement of the central nervous system in lymphoma if accompanied by neurological symptoms. In addition, in patients with a markedly elevated LDH or soluble interleukin-2 receptor level without lymphadenopathy, IVL should be suspected, and consultation with hematologists should be considered.

Prognostic Nutritional Index in Patients With End-Stage Oral Cancer.

PURPOSE: As the incidence of oral cancers is on the rise, we aimed to evaluate the usefulness of the prognostic nutritional index (PNI) as a predictor of survival in patients with terminal oral cancer. METHODS: We evaluated the association between laboratory and PNI values and survival days in 33 patients who died of oral cancer between 2004 and 2019 ,excluding 4 patients who underwent gastric banding out of 39with gastric banding. The observation period was from the date of palliative care recommendation to the date of death. RESULTS: A significant difference was observed between the PNI values recorded 3 months before death and those recorded 1 month before death (37.99 ± 6.50 vs 28.86 ± 6.01; P<.05). The median PNI value was associated with the timing of supportive care start and survival (days). CONCLUSION: This study revealed that PNI values decreased toward the end of life and correlated with survival (days), independent of patient characteristics. These findings suggest that the PNI may be useful in the prognostication of end-stage oral cancer.

Effects of Using a Video-Sharing Application on Multidisciplinary Staff During Pre-discharge Home Assessment Visits for Elderly Hospitalized Patients.

Background: Pre-discharge home assessment visits for elderly hospitalized patients are conducted by the hospital staff to ensure a smooth transition to home care and are effective in preventing falls and reducing the rehospitalization rates. However, the effect of an application that enables the viewing of videos of the patient's home activities during the pre-discharge visit on the multidisciplinary professionals who provide services to the patient has not yet been fully clarified. Methods: Multidisciplinary professionals at 23 facilities located in western Tottori Prefecture who used a video-sharing application (Patto-Mie Net) were invited to be interview participants. Those who agreed were interviewed about the usefulness of the application in their work and its effect on multidisciplinary collaboration. A verbatim transcript was made, and thematic analysis was conducted using the qualitative analysis software NVivo. Results: Twenty-eight people participated in the interviews, including nurses, care managers, rehabilitation specialists, care workers, and other social care professions. Fourteen themes and five categories were generated from the analysis: comprehensive information visualization and transferability, identification of changes over time and prognostic prediction, promoting multidisciplinary collaboration, patient and family reality, and disadvantages and concerns. Conclusion: The use of an application that allows video-sharing of a patient's home movement status during a pre-discharge visit has revealed a variety of benefits for multiple professionals in hospitals and other facilities. In particular, the results were characterized by the psychological closeness between multiple professionals, promotion of interprofessional communication, and sharing of reality, including the psychosocial background of the patient and family.

Late-Onset Intracranial Hemorrhage Presenting as Refractory Hyponatremia: A Case Report.

Here, we report a case of refractory hyponatremia and delayed intracranial hemorrhage following a head injury. A 70-year-old male patient was admitted with complaints of left chest pain and light-headedness after a fall. Hyponatremia recurred despite the correction with intravenous saline. Head computed tomography revealed a chronic subdural hematoma. The subsequent introduction of tolvaptan improved hyponatremia and disorientation. Delayed intracranial hemorrhage is a differential cause of refractory hyponatremia after head contusion. This case is clinically relevant because (i) the diagnostic delay of late-onset intracranial hemorrhage is common but fatal, and (ii) refractory hyponatremia can be a hint of late-onset intracranial hemorrhage.
