What are the barriers to medical collaboration in community-based integrated care supporting cancer patients? A qualitative analysis of healthcare and long-term care providers' perceptions.

BACKGROUND: Patients required comprehensive cancer treatment in the community based on medical collaboration between designated cancer care hospitals and community medical and nursing care facilities to help them live life on their own terms. This study aims to describe the barriers to medical collaboration in community-based integrated care from the perspectives of healthcare providers (HCPs) and long-term care providers (LCPs) supporting cancer patients. METHODS: Semi-structured interviews were conducted with 88 HCPs and LCPs supporting cancer patients. We analyzed interview data to describe barriers to medical collaboration between designated cancer care hospitals and community medical and nursing care facilities using content analysis in MAXQDA. RESULTS: Participants were mostly HCPs, with physicians accounting for the largest proportion (27.3%). Totally, 299 codes were integrated into seven barriers to medical collaboration in community-based integrated care, including lack of information provision including life perspectives and a delay in sharing cancer patients' values with HCPs to provide end-of-life care according to the patients' wishes. Furthermore, insufficient coordination of cancer and non-cancer symptom management was identified as a barrier specific to older adults with cancer. CONCLUSIONS: Barriers related to cancer treatment that integrate lifestyle perspectives, end-of-life care emphasizing patient values, and medical collaboration between cancer and non-cancer care are distinctive. They emphasize the importance of utilizing professionals to connect treatment and lifestyle information, establishing a central coordinating organization led by the DCCH, and developing a community palliative care network. Moreover, connecting cancer and non-cancer care through government and medical collaboration is crucial.

Automatic Classification of Electronic Nursing Narrative Records Based on Japanese Standard Terminology for Nursing.

In Japan, nursing records are not easily put to secondary use because nursing documentation is not standardized. In recent years, electronic health records have necessitated the creation of Japanese nursing terminology. The purpose of this study was to develop and evaluate an automatic classification system for narrative nursing records using natural language processing technology and machine learning. We collected a week's worth of narrative nursing records from an academic hospital. The authors independently annotated the text data, dividing it into morphemes, the smallest meaningful unit in a language. During preprocessing when creating feature quantities, we used a Japanese tokenizer, MeCab, an open-source morphological parser, and the bag-of-words model. A support vector machine was adopted as a classifier for machine learning. The accuracy was 0.96 and 0.86 on the training set and test set, respectively, and the F value was 0.82. Our findings provide useful information regarding the development of an automatic classification system for Japanese nursing records using nursing terminology and natural language processing techniques.

Prostaglandin D2 Modulates Neuronal Excitation of the Trigeminal Ganglion to Augment Allergic Rhinitis in Guinea Pigs.

Prostaglandin D2(PGD2) is involved in the pathogenesis of allergic rhinitis. However, the sensory nervous system-mediated contributions of PGD2to the symptoms of allergic rhinitis remain unclear. We investigated the involvement of PGD2in these symptoms and in neuronal excitation by in vivo and ex vivo experiments. In an ovalbumin-induced model of allergic rhinitis in guinea pigs, the number of sneezing, nasal rubbing, and nasal secretion events were assessed after the nasal cavity instillation of PGD2, histamine, or a combination of PGD2and histamine. In situ hybridization for PGD2receptor 1 (DP1) mRNA transcripts and immunohistochemical analysis of histamine H1receptor protein expression in guinea pig trigeminal ganglion (TRG) were performed. The effects of DP1receptor activation on the excitability of TRG neurons to electrical and histamine stimuli were assessed using whole-cell patch-clamp recordings. Histamine induced more sneezing, nasal rubbing, and nasal secretion events than PGD2 PGD2augmented histamine-induced responses, whereas pretreatment with a DP1receptor-selective antagonist completely suppressed PGD2-induced augmentation. DP1receptor mRNA transcripts and H1receptor protein expression could be detected in TRG neurons. Moreover, a DP1receptor agonist caused significant increases in the number of histamine-induced action potentials and depolarization, and reduced the current threshold in small-diameter neurons. Our findings show that PGD2-DP1receptor signaling augments the symptoms of allergic rhinitis via the sensory nervous system by modulating nasal neuronal activation to various stimuli, such as histamine. These findings suggest that DP1receptor antagonist has therapeutic potential for the treatment of allergic rhinitis.

Nationwide Survey on Caregiver Burden When Supporting Terminal Cancer Patients with Dementia: Bereaved Family Members' Perspective.

Objective: The prevalence of dementia and cancer has increased in recent years. The presence of dementia complicates the care of terminal cancer patients and affects their family caregivers. However, palliative care research seldom focuses on the family caregivers of patients with terminal cancer and dementia. This study aimed to evaluate the degree and factors of caregiver burden in cancer patients with dementia who died in hospice palliative care units. Methods: A nationwide cross-sectional survey was conducted among bereaved family members of patients with cancer who died in palliative care units. An anonymous self-report questionnaire was sent to bereaved family members, and they were asked if they were aware of the diagnosis of dementia. The short version of the Caregiver Consequence Inventory was used to measure caregiver burden. Results: The analysis included 670 bereaved family members. Of these, 83 (12.4%) were bereaved family members of terminal cancer patients with dementia. The caregiver burden was statistically significantly higher (3.61 ± 1.58 vs 3.22 ± 1.47; p < 0.036) among family caregivers of terminal cancer patients with dementia. Longer anti-cancer treatment duration (odd ratio, 4.63), poor mental and physical health of family caregivers (odds ratio, 2.05 and 2.20, respectively), pain (odd ratio, 1.72), and dyspnea (odds ratio, 1.67) were contributing factors for caregiver burden. Conclusions: Family caregivers of terminal cancer patients with dementia require care that considers the characteristics of the two serious diseases. Considering the goal of anti-cancer treatment and symptom relief may be a useful strategy for reducing caregiver burden.

Autonomic function measurements for evaluating fatigue and quality of life in patients with breast cancer undergoing radiation therapy: a prospective longitudinal study.

BACKGROUND: Fatigue during radiation therapy in women with breast cancer can decrease quality of life (QOL), yet it is often underestimated and needs to be evaluated objectively. This longitudinal study aimed to evaluate fatigue and QOL of women with breast cancer undergoing radiotherapy with a simple autonomic function measurement. METHODS: Women with breast cancer who underwent postoperative radiotherapy in eight cancer care hospitals in Chubu and Kinki regions in Japan were recruited between October 2021 and June 2022. The women underwent a self-administered questionnaire that included the Cancer Fatigue Scale (CFS) and the Short Form-8 Health Survey (SF-8) and an autonomic nervous function measurement using a simple, non-invasive device before (T0, baseline), mid (T1), and at the end (T2) of treatment. RESULTS: The 57 women showed similar trends, with CFS scores and log LF/HF ratio being the highest at T0 and significantly decreasing at T1 (both p < 0.05). The log LF/HF trends differed between those with high and low baseline log LF/HF values. Women with mental component summary (MCS) score improvement (T0 to T2) had the highest log LF/HF ratio at T0 and had significantly lower log LF/HF values at T1 and T2 than at T0 (p < 0.01 and p < 0.05, respectively). The change of (⊿) MCS from T0 to T1 was negatively correlated with ⊿log LF/HF from T0 to T1 (r = - 0.36, p < 0.01). CONCLUSIONS: Measurement of autonomic nerve function with a simple device is useful for objective fatigue assessment during radiotherapy. Psychological support is important as improvement in mental health helps improve autonomic nerve function and, in turn, fatigue.

Immune response and protective efficacy of the SARS-CoV-2 recombinant spike protein vaccine S-268019-b in mice.

Vaccines that efficiently target severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the etiological agent for coronavirus disease (COVID-19), are the best means for controlling viral spread. This study evaluated the efficacy of the COVID-19 vaccine S-268019-b, which comprises the recombinant full-length SARS-CoV-2 spike protein S-910823 (antigen) and A-910823 (adjuvant). In addition to eliciting both Th1-type and Th2-type cellular immune responses, two doses of S-910823 plus A-910823 induced anti-spike protein IgG antibodies and neutralizing antibodies against SARS-CoV-2. In a SARS-CoV-2 challenge test, S-910823 plus A-910823 mitigated SARS-CoV-2 infection-induced weight loss and death and inhibited viral replication in mouse lungs. S-910823 plus A-910823 promoted cytokine and chemokine at the injection site and immune cell accumulation in the draining lymph nodes. This led to the formation of germinal centers and the induction of memory B cells, antibody-secreting cells, and memory T cells. These findings provide fundamental property of S-268019-b, especially importance of A-910823 to elicit humoral and cellular immune responses.

Care Associated With Satisfaction of Bereaved Family Members of Terminally Ill Cancer Patients With Dyspnea: A Cross-sectional Nationwide Survey.

CONTEXT: Terminal dyspnea in dying cancer patients is frequent and distressing, and the impact extends to their families. Families are often involved in providing care for terminal dyspnea. OBJECTIVES: This study aimed to describe various care strategies for terminal dyspnea in cancer patients hospitalized in palliative care units (PCUs), evaluate families' satisfaction with care for terminal dyspnea, and explore determinants contributing to families' satisfaction. METHODS: A nationwide, cross-sectional survey was conducted using a self-reported questionnaire among bereaved families of cancer patients who died in PCUs. The questionnaire consisted of questions on the perceptions of care offered to patients with terminal dyspnea and their families, satisfaction with care for terminal dyspnea, family-perceived intensity of terminal dyspnea, use of oxygen, and background data of patients and families. RESULTS: In total, 533 participants (response rate = 54%) returned the completed questionnaires, and 231 reported that their loved one had experienced terminal dyspnea. Dedicated and compassionate care was perceived by 60%-89% of the participants as the strategy provided for patients. Care for family members was perceived by 58%-69% of the participants. Perception of dedicated and compassionate care for patients and that of care for family members were significantly associated with high satisfaction (odds ratio, 95% confidence interval: 8.64, 3.85-19.36 and 15.37, 5.00-47.25, respectively). CONCLUSION: Dedicated and compassionate care may be the essential part of the care for terminal dyspnea. Dedicated and compassionate care for patients and care for family members have a potential of improving the care satisfaction among family caregivers.

Decision Making Regarding the Place of End-of-Life Cancer Care: The Burden on Bereaved Families and Related Factors.

CONTEXT: Decision making regarding the place of end-of-life (EOL) care is an important issue for patients with terminal cancer and their families. It often requires surrogate decision making, which can be a burden on families. OBJECTIVES: To explore the burden on the family of patients dying from cancer related to the decisions they made about the place of EOL care and investigate the factors affecting this burden. METHODS: This was a cross-sectional mail survey using a self-administered questionnaire. Participants were 700 bereaved family members of patients with cancer from 133 palliative care units in Japan. The questionnaire covered decisional burdens, depression, grief, and the decision-making process. RESULTS: Participants experienced emotional pressure as the highest burden. Participants with a high decisional burden reported significantly higher scores for depression and grief (both P < 0.001). Multiple regression analyses revealed that higher burden was associated with selecting a place of EOL care that differed from that desired by participants (P < 0.001) and patients (P = 0.034), decision making without knowing the patient's wishes and values (P < 0.001) and without participants sharing their wishes and values with the patient's doctors and/or nurses (P = 0.022), and making the decision because of a due date for discharge from a former facility or hospital (P = 0.005). CONCLUSION: Decision making regarding the place of EOL care was recalled as burdensome for family decision makers. An early decision-making process that incorporates sharing patients' and family members' values that are relevant to the desired place of EOL care is important.

Potential role of IL-17-producing CD4/CD8 double negative αß T cells in psoriatic skin inflammation in a TPA-induced STAT3C transgenic mouse model.

BACKGROUND: Psoriasis is one of the most common immune-mediated chronic inflammatory skin disorders and is accompanied by erythematous scaly plaques. There is growing evidence that the IL-23/Th17 axis plays a critical role in development of the disease. It was recently shown that in addition to CD4+ Th17 cells, various IL-17-producing cell subsets such as CD8+ Tc17 cells, dermal γδ T cells, and innate lymphoid cells are also involved in the development of psoriatic inflammation in humans. OBJECTIVE: To investigate which subsets of IL-17-producing cells are involved in psoriasis-like skin inflammation in a TPA (tumor promoter 12-O-tetradecanoylphorbol-13-acetate)-induced K14.Stat3C mouse model. METHOD: Skin-infiltrating cells were isolated from inflamed lesions of TPA-treated K14.Stat3C transgenic mice, and analyzed for IL-17 producing cell subsets by flow cytometry. RESULTS: We observed significantly increased numbers of IL-17-producing CD4+ T cells, CD8+ T cells and dermal γδ T cells in TPA-induced skin lesions of K14.Stat3C mice. Additionally, we found that another IL-17-producing T cell subset, αß-TCR+ CD4CD8 double negative T cells (DN αß T cells), was also increased in lesional skin. These IL-17-producing DN αß T cells are NK1.1 negative, suggesting they are not natural killer T cells or mucosal associated invariant T cells. As well as other IL-17-producing cells, DN αß T cells in the inflamed skin can also respond to IL-23 stimulation to produce IL-17. It is also suggested that DN αß T cells may express retinoic acid-related orphan receptor gamma t and CC chemokine receptor 6. CONCLUSION: In TPA-induced lesional skin of K14.Stat3C mice, IL-17-producing CD4+ Th17 cells, CD8+ Tc17 cells, dermal γδ T cells and TCR- cells probably containing ILCs all participated in skin inflammation, which is similar to human clinical psoriatic features. Furthermore, we showed for the first time the possibility that an IL-17-producing DN αß T cell subset is also involved in psoriatic inflammation.

Predictive genomic biomarkers for drug-induced nephrotoxicity in mice.

The present study aimed to establish candidate biomarker genes for the early detection of nephrotoxicity in mice, with a particular focus on nephrotoxicity caused by polyene macrolides. Comprehensive gene expression changes were evaluated using microarrays in a mouse model in which acute nephrotoxicity was induced by amphotericin B deoxycholate, trade name Fungizone. The upregulated genes identified through microarray analysis of kidney tissue of Fungizone-treated mice included several genes that have been reported as nephrotoxicity biomarkers in rats, and 14 genes were selected as candidate nephrotoxicity biomarkers. The usefulness of these genes as nephrotoxicity biomarkers in mice was evaluated further through expression profiling under several experimental conditions using real time RT-PCR. Expression of genes encoding kidney injury molecule 1, lipocalin 2, tissue inhibitor of metalloproteinase 1, and secreted phosphoprotein 1 was highly upregulated by Fungizone, nystatin, natamycin, amphotericin B methyl ester, and liposomal amphotericin B, and their area under the ROC curve values were more than 0.95. These genes were more sensitive at detecting nephrotoxicity than traditional clinical chemistry and histopathology parameters. This study provides novel evidence that these nephrotoxicity biomarker genes identified are translatable to mice, and that they are useful for early and sensitive detection of nephrotoxicity.

Plasma corticosterone activates SGK1 and induces morphological changes in oligodendrocytes in corpus callosum.

Repeated stressful events are known to be associated with onset of depression. Further, stress activates the hypothalamic-pituitary-adrenocortical (HPA) system by elevating plasma cortisol levels. However, little is known about the related downstream molecular pathway. In this study, by using repeated water-immersion and restraint stress (WIRS) as a stressor for mice, we attempted to elucidate the molecular pathway induced by elevated plasma corticosterone levels. We observed the following effects both, in vivo and in vitro: (1) repeated exposure to WIRS activates the 3-phosphoinositide-dependent protein kinase (PDK1)-serum glucocorticoid regulated kinase (SGK1)-N-myc downstream-regulated gene 1 (NDRG1)-adhesion molecule (i.e., N-cadherin, α-catenin, and ß-catenin) stabilization pathway via an increase in plasma corticosterone levels; (2) the activation of this signaling pathway induces morphological changes in oligodendrocytes; and (3) after recovery from chronic stress, the abnormal arborization of oligodendrocytes and depression-like symptoms return to the control levels. Our data strongly suggest that these abnornalities of oligodendrocytes are possibly related to depression-like symptoms.

EphA receptors direct the differentiation of mammalian neural precursor cells through a mitogen-activated protein kinase-dependent pathway.

Ephrins are cell surface-associated ligands for Eph receptor tyrosine kinases and are implicated in repulsive axon guidance and cell migration. EphA2, 3, and 4 receptors and one of their cognate ligands, ephrin-A2, are expressed by cells in the subventricular zone and ganglionic eminence of the embryonic day 14.5 telencephalon and by neural precursor cells in vitro. Activation of EphA receptors in dissociated neural precursor cells in vitro facilitates the commitment to neuronal fates. The majority of ephrin-A1-induced neurons is immunoreactive for tyrosine hydroxylase. Blocking the signal by the extracellular domain of EphA in forebrain slices results in a decrease in neurogenesis. Extracellular signal-regulated kinase is activated by the ligand binding to EphA receptors and is involved in the neurogenesis through EphA receptors. Rap1, but not Ras, is activated in response to ephrin-A1. Our results identify EphA receptors as positive regulators of the mitogen-activated protein kinase pathway that exerts neurogenesis of neural precursor cells from the developing central nervous system.

The p75 receptor is required for BDNF-induced differentiation of neural precursor cells.

Epidermal growth factor (EGF)-treated neurospheres from fetal forebrain contain multipotential cells capable of neuronal, astrocytic, and oligodendroglial differentiation. These neural precursor cells express the TrkB as well as the neurotrophin receptor p75 (p75NTR), suggesting that they are BDNF responsive. In this study, we test whether the p75NTR plays a role in the differentiation of these neural precursor cells in vitro. Activation of the TrkB and the p75NTR by the addition of BDNF facilitates neuronal commitment and marked neurite genesis. However, no promotion of neuronal commitment by BDNF was observed in the neural precursor cells from mice carrying a mutation in the p75NTR gene. In addition, we observed a significant increase in the number of nestin-positive cells and the proliferation of the cells lacking functional p75NTR. These findings suggest that the p75NTR is required for proper neuronal fate decision as well as the differentiation of the neural precursor cells.
