Background Clinical guidelines recommend antipsychotics for the treatment of delirium; however, there has been no confirmed recommendation regarding their administrating patterns. This study aims to investigate whether different dosing patterns of antipsychotics (single or multiple administrations) influence the outcomes of delirium treatment. Methods This is a secondary analysis of a prospective observational study involving patients with advanced cancer and delirium receiving antipsychotics. The Delirium Rating Scale Revised-98 was administered at baseline and after 72 h of starting pharmacotherapy. Patients were classified into single administration group (received a single dosage within 24 h before the assessment) and multiple administration group (received more than one dosage). Results A total of 555 patients (single administration 492 (88.6%); multiple administration 63 (11.4%)) were subjected to analyses. The patients in the multiple administration group were more likely to be male, in psycho-oncology consulting settings, with lower performance status, with hyperactive delirium and with severer delirium symptoms. In the multivariate analysis, single administration was significantly associated with better improvement of delirium (p Conclusions In this observational study sample, Delirium Rating Scale severity score improvement in single administration was higher than that seen in multiple administration. There was no difference in adverse events between the two groups.

PURPOSE: Patients' values and priorities in their lives should be appreciated from an early phase of incurable diseases such as advanced cancer. However, studies examining these characteristics have been lacking. This study attempted to determine what patients with advanced lung cancer valued most, once they had been diagnosed, and any associated factors. METHODS: Patients with newly diagnosed advanced lung cancer (N = 248) were enrolled in a questionnaire survey conducted at 16 hospitals in Japan. Their priorities were assessed using a free-text response to the question what is the most important thing to you now? at the time of diagnosis and 3 months after diagnosis. The free-text responses were classified into 10 categories for quantification. The clinical characteristics associated with the category describing daily life were further examined. RESULTS: Free-text comments were obtained from 103 (44.0%) and 66 (42.6%) patients at the time of diagnosis and at 3 months, respectively. The most frequent categories were family (at diagnosis: 50.5%; at 3 months: 50.0%) and daily life (at diagnosis: 33.0%; at 3 months: 36.4%), followed by health (at diagnosis: 32.0%; at 3 months: 27.3%) at both time points. The patients mentioning daily life, the issues related to how to spend daily life, showed significantly higher total scores and functional well-being subscale scores on the Functional Assessment of Cancer Therapy-Lung scale at both time points and lower depression scores at diagnosis and lower anxiety scores at 3 months on the Hospital Anxiety and Depression Scale. CONCLUSION: Family and daily life were highly valued by patients with advanced lung cancer at diagnosis. A better quality of life and better mood were associated with mentioning daily life, which should be taken into account in care planning to maintain patients' involvement in daily life even with incurable diseases.

Objective The Japanese Psycho-Oncology Society and the Japanese Association of Supportive Care in Cancer have recently revised the clinical practice guidelines for delirium in adult cancer patients. This article reports the process of developing the revised guidelines and summarizes the recommendations made. Methods The guidelines were developed in accordance with the Medical Information Network Distribution Service creation procedures. The guideline development group, consisting of multi-disciplinary members, created three new clinical questions: non-pharmacological intervention and antipsychotics for the prevention of delirium and trazodone for the management of delirium. In addition, systematic reviews of nine existing clinical questions have been updated. Two independent reviewers reviewed the proposed articles. The certainty of evidence and the strength of the recommendations were graded using the grading system developed by the Medical Information Network Distribution Service, following the concept of The Grading of Recommendations Assessment, Development, and Evaluation system. The modified Delphi method was used to validate the recommended statements. Results This article provides a compendium of the recommendations along with their rationales, as well as a short summary. Conclusions These revised guidelines will be useful for the prevention, assessment and management of delirium in adult cancer patients in Japan.

Background: Both advanced cancer patients and their family caregivers experience distress and have a range of concerns after cancer diagnosis. However, longitudinal studies on this topic have been lacking. Aim: To investigate concerns in both patients with advanced lung cancer and their family caregivers longitudinally from diagnosis. Design: A multi-center prospective questionnaire-based study. Setting/participants: We recruited patients with newly diagnosed advanced lung cancer and their family caregivers at 16 hospitals in Japan. We prospectively assessed the prevalence of their concerns using the Concerns Checklist and investigated the associations between their concerns and mental status as well as quality of life until 24 months after diagnosis. Results: A total of 248 patients and their 232 family caregivers were enrolled. The prevalence of serious concerns was highest at diagnosis (patients: 68.3%, family caregivers: 65.3%). The most common serious concern was concern about the future in both groups at diagnosis (38.2% and 40.5%, respectively) and this remained high in prevalence over time, while the high prevalence of concern about lack of information improved 3 months after diagnosis in both groups. Approximately one-third of patient-family caregiver dyads had discrepant reports of serious concerns. The presence of serious concerns was significantly associated with anxiety and depression continuously in both groups. Conclusions: The majority of advanced lung cancer patients and their family caregivers have serious concerns from diagnosis, which is associated with their psychological distress. The spectrum of concerns alters over the disease trajectory, warranting efficient tailored care and support for both groups immediately after diagnosis.

Background The Japanese Psycho-Oncology Society and Japanese Association of Supportive Care in Cancer recently launched the clinical practice guidelines for delirium in adult cancer patients. The aim of the guidelines was to provide evidence-based recommendations for the clinical assessment and management of delirium in cancer patients. This article reports the process of developing the guideline and summarizes the recommendations made. Methods The guidelines were developed in accordance with the Medical Information Network Distribution Service creation procedures. The guideline development group, consisting of multidisciplinary members, formulated nine clinical questions. A systematic literature search was conducted to identify relevant articles published prior to through 31 May 2016. Each article was reviewed by two independent reviewers. The level of evidence and the strength of the recommendations were graded using the grading system developed by the Medical Information Network Distribution Service, following the concept of The Grading of Recommendations Assessment, Development and Evaluation system. The modified Delphi method was used to validate the recommendation statements. Results This article provides a summary of the recommendations with rationales for each, as well as a short summary. Conclusions These guidelines will support the clinical assessment and management of delirium in cancer patients. However, additional clinical studies are warranted to further improve the management of delirium., The Japanese Psycho-Oncology Society and Japanese Association of Supportive Care in Cancer launched the guidelines for delirium. This article reports the process of developing the guideline and summarizes the recommendations.

Background Accurate prognostic understanding in patients with advanced cancer is essential for shared decision making; however, patients may experience psychological burden through knowing the incurable nature of advanced cancer. It has been unclear how their prognostic understanding fluctuates and whether accurate prognostic understanding is associated with psychological distress from the time of diagnosis over time. Materials and Methods We longitudinally investigated prognostic understanding in 225 patients with newly diagnosed advanced lung cancer at 16 hospitals in Japan until 24 months after diagnosis. We examined associated factors with being consistently accurate in prognostic understanding, especially focusing on its association with psychological well-being. Results The proportion of patients with an inaccurate prognostic understanding remained approximately 20% over time with the presence of patients with inconsistent understanding. Patients with consistently accurate prognostic understanding showed a significantly lower Emotional Well-Being subscale score at both 3 and 6 months after diagnosis (p = .010 and p = .014, respectively). In multivariate analyses, being consistently accurate in prognostic understanding was significantly associated with female gender and higher lung cancer–specific symptom burden at 3 months (p = .008 and p = .005, respectively) and lower emotional well-being at 6 months (p = .006). Conclusion Although substantial proportions of patients with advanced lung cancer had inaccurate prognostic understanding from the time of diagnosis over time, patients with consistently accurate prognostic understanding experienced greater psychological burden. Our findings highlight the importance of continuous psychological care and support for patients who understand their severe prognosis accurately. Implications for Practice This study demonstrated that approximately 20% of patients with advanced lung cancer had an inaccurate understanding about their prognosis, not only at the time of diagnosis but also at the later time points. Being consistently accurate in prognostic understanding was significantly associated with elevated levels of psychological distress. Although accurate prognostic understanding is essential for decision making for treatment and advance care planning, health care providers should be aware of psychological burdens in patients that accept their severe prognosis accurately. Appropriate care and support for such patients are warranted from diagnosis over time.

Background Patient participation is a key foundation of advance care planning (ACP). However, a patient himself/herself may be left out from sensitive conversations such as end-of-life (EOL) care discussions. The objectives of this study were to investigate patients’ participation rate in the discussion of Cardiopulmonary Resuscitation (CPR) / Do-Not-Attempt-Resuscitation (DNAR) order, and in the discussion that the patient is at his/her EOL stage (EOL disclosure), and to explore their associated factors. Methods This is a retrospective chart review study. The participants were all the patients who were hospitalized and died in a university-affiliated teaching hospital (tertiary medical facility) in central Tokyo, Japan during the period from April 2018 to March 2019. The following patients were excluded: (1) cardiopulmonary arrest on arrival; (2) stillbirth; (3) under 18 years old at the time of death; and (4) refusal by their bereaved family. Presence or absence of CPR/DNAR discussion and EOL disclosure, patients’ involvement in those discussions, and their associated factors were investigated. Results CPR/DNAR discussions were observed in 336 out of the 358 patients (93.9%). However, 224 of these discussions were carried out without a patient (patient participation rate 33.3%). Male gender (odds ratio (OR) = 2.37 [95% confidence interval (CI) 1.32–4.25]), living alone (OR = 2.51 [1.34–4.71]), and 1 year or more from the date of diagnosis (OR = 1.78 [1.03–3.10]) were associated with higher patient’s participation in CPR/DNAR discussions. The EOL disclosure was observed in 341 out of the 358 patients (95.3%). However, 170 of the discussions were carried out without the patient (patient participation rate 50.1%). Patients who died of cancer (OR = 2.41[1.45–4.03]) and patients without mental illness (OR=2.41 [1.11–5.25]) were more likely to participate in EOL disclosure. Conclusions In this clinical sample, only up to half of the patients participated in CPR/DNAR discussions and EOL disclosure. Female, living with family, a shorter period from the diagnosis, non-cancer, and mental illness presence are risk factors for lack of patients’ participation in CPR/DNAR or EOL discussions. Further attempts to facilitate patients’ participation, based on their preference, are warranted.

Background Prognostic understanding in advanced cancer patients and their caregivers may have an impact on the delivery of effective care. The aims of this study were to explore prognostic understanding at diagnosis in both patients with advanced lung cancer and their caregivers and to investigate correlates of their understanding. Subjects, Materials, and Methods A total of 193 patients with newly diagnosed advanced lung cancer and their 167 caregivers were enrolled at 16 hospitals in Japan. We assessed their perceptions of prognosis and goals of therapy and examined their associations with their sociodemographic characteristics, clinical status, quality of life, mood symptoms, and the status of disclosure of information by their treating physicians. Results One fifth of patients and caregivers (21.7% and 17.6%, respectively) mistakenly believed that the patients’ cancer was “completely curable.” Substantial proportions of them (16.9% and 10.3%, respectively) mistakenly believed that the primary goal of therapy was to remove all the cancer. Levels of anxiety and depression in both patients and caregivers were significantly higher among those who had accurate understanding of prognosis. In multivariate analyses, inaccurate perceptions of prognosis in patients were associated with sex, better emotional well-being, and lower lung cancer-specific symptom burden. Caregivers’ inaccurate perceptions of patients’ prognoses were associated with better performance status and better emotional well-being of patients. Conclusion Substantial proportions of advanced lung cancer patients and their caregivers misunderstood their prognosis. Interventions to improve their accurate prognostic understanding should be developed with careful attention paid to its associated factors. Implications for Practice This study demonstrated that substantial proportions of patients with newly diagnosed advanced lung cancer and their caregivers had misunderstandings about their prognosis. Accurate perceptions of prognosis, which are indispensable in the delivery of effective care, were associated with elevated levels of anxiety and depression in both patients and caregivers, warranting psychosocial care and support for them immediately after diagnosis. Inaccurate perceptions of prognosis in patients were associated with better emotional well-being and lower lung cancer-specific symptom burden. Illness understanding in caregivers was associated with patients’ physical and mental status. Those findings provide insight into how they obtain accurate illness understanding.

TDP-43 is an RNA-binding protein important for many aspects of RNA metabolism. Abnormal accumulation of TDP-43 in the cytoplasm of affected neurons is a pathological hallmark of the neurodegenerative diseases frontotemporal dementia (FTD) and amyotrophic lateral sclerosis (ALS). Several transgenic mouse models have been generated that recapitulate defects in TDP-43 accumulation, thus causing neurodegeneration and behavioural impairments. While aging is the key risk factor for neurodegenerative diseases, the specific effect of aging on phenotypes in TDP-43 transgenic mice has not been investigated. Here, we analyse age-dependent changes in TDP-43 transgenic mice that displayed impaired memory. We found the accumulation of abundant poly-ubiquitinated protein aggregates in the hippocampus of aged TDP-43 transgenic mice. Intriguingly, the aggregates contained some interneuron-specific proteins such as parvalbumin and calretinin, suggesting that GABAergic interneurons were degenerated in these mice. The abundance of aggregates significantly increased with age and with the overexpression of TDP-43. Gene array analyses in the hippocampus and other brain areas revealed dysregulation in genes linked to oxidative stress and neuronal function in TDP-43 transgenic mice. Our results indicate that the interneuron degeneration occurs upon aging, and TDP-43 accelerates age-dependent neuronal degeneration, which may be related to the impaired memory of TDP-43 transgenic mice.

Objectives Mindfulness-based intervention has been receiving growing attention in cancer care. This study aimed to examine feasibility and to preliminary explore effectiveness of mindfulness-based cognitive therapy (MBCT) in Japanese breast cancer patients, and to explore possible modification of the program so that it fits better with this population. Methods Twelve participants with diagnosis of Stage I-III breast cancer received an eight session, weekly MBCT intervention in a group therapy format. The participants were followed up until 3 months after the completion of the program. Results All the participants completed the program with high attendance rate (mean number of attended sessions = 7.7). Significant improvement in anxiety (Hospital Anxiety and Depression Scale (HADS) - anxiety subscale; effect size Cohen's d = 0.88, P < 0.05), trauma-related psychological symptoms (Impact of Event Scale-revised; d = 0.64, P < 0.01) and quality of life (Functional Assessment of Cancer Therapy-Breast Cancer: FACT-B; d = 0.72, P < 0.01), and trend-level improvement in depression (HADS - depression subscale; d = 0.53, P = 0.054) were observed. Qualitative analyses suggested the program may be beneficial for alleviating fear of cancer recurrence and for increasing spiritual well-being. Some recommended modification of the program was indicated from the post-intervention interviews. Conclusions Mindfulness-based cognitive therapy was well accepted by Japanese breast cancer patients and yielded favorable effect on their psychological status and quality of life. Further effectiveness study in a randomized-control design is warranted.

Background Postoperative delirium is common after extensive surgery, and is known to be associated with sleeping medications. In this study, we aimed to investigate the relationships between sleeping medications and postoperative delirium after pharyngolaryngectomy with esophagectomy. Methods We performed a retrospective analysis of 65 patients who underwent pharyngolaryngectomy with esophagectomy at Shizuoka Cancer Center Hospital between January 2012 and March 2016. All data were assessed by two psychiatrists, and univariate and multivariate analyses were performed. Results Postoperative delirium developed in 9 (13.8%) patients, with most cases (77.8%) occurring between postoperative day (POD) 1 and POD 3. Of the 24 patients taking a minor tranquilizer after surgery, 8 (33.3%) became delirious, but, of the remaining 41 patients taking ramelteon with or without suvorexant, only one (2.4%) became delirious after surgery. Moreover, of the 16 patients taking both ramelteon and suvorexant, no postoperative delirium was observed. Ramelteon with or without suvorexant was significantly associated with a decreased rate of postoperative delirium compared with minor tranquilizer use (p = 0.001). Multivariate analysis confirmed that the use of ramelteon with or without suvorexant was the only significant preventive factor of postoperative delirium (odds ratio 0.060, p = 0.013). Conclusion The use of ramelteon with or without suvorexant was the only significant preventive factor of postoperative delirium after pharyngolaryngectomy with esophagectomy. However, using minor tranquilizers was associated with postoperative delirium. We recommend ramelteon with or without suvorexant for preventing postoperative delirium after pharyngolaryngectomy with esophagectomy.

Background Postoperative delirium is a common and serious complication after extensive surgery. This study aimed to investigate the incidence and risk factors for postoperative delirium after major head and neck cancer surgery. Methods A retrospective analysis was performed for 293 patients who underwent major head and neck cancer surgery lasting >6 h at our institution between January 2012 and November 2015. All data were assessed by two psychiatrists. Univariate and multivariate analyses were performed. Results Postoperative delirium developed in 50 (17.1%) patients; most cases (84.0%) of postoperative delirium were observed between postoperative day (POD) 1 and POD 3. Multivariate analysis revealed that an age >70 years was the significant risk factor for postoperative delirium incidence after major head and neck cancer surgery; the multivariate hazard ratio was 3.935 (95% confidence interval 1.873–8.265, p Conclusions Most cases of postoperative delirium after major head and neck cancer surgery were observed between POD 1 and POD 3, and a multivariate analysis revealed that an age >70 years was a significant risk factor for postoperative delirium incidence. Clinicians should pay particular attention to the possibility of delirium incidence during the first 3 days after surgery for patients aged >70 years.

Postoperative delirium is a common complication after major surgery and is characterized by acute confusion with fluctuating consciousness. The aim of this study was to investigate the incidence and risk factors of postoperative delirium in patients with esophageal cancer.We conducted a retrospective cohort analysis of 306 consecutive patients who had undergone an esophagectomy at Keio University Hospital from January 1998 to December 2009. All data were assessed by psychiatrists, and delirium was diagnosed according to criteria of the Diagnostic and Statistical Manual Disorder, fourth edition. Univariate and multivariate analyses were performed.Postoperative delirium developed in 153 (50.0 %) of 306 patients. One hundred fourteen (37.3 %) of the 306 patients required psychoactive medication for symptoms associated with delirium. Univariate analyses showed that older age, male gender, additional flunitrazepam for sedation in intensive care unit (ICU) after surgery, longer periods of time under mechanical ventilation after surgery, longer ICU stays, occurrence of postoperative complications, and longer hospital stays were significantly associated with postoperative delirium. Multivariate analysis revealed that development of delirium was linked to older age, additional flunitrazepam in ICU, and occurrence of postoperative complication.The development of postoperative delirium in patients with esophageal cancer is a problem that cannot be ignored. Our results suggest that the risk of developing delirium is associated with older age, use of flunitrazepam in ICU, and postoperative complications.

We present an improvement of energy density analysis (EDA), which partitions the total energy obtained by Hartree–Fock and/or density functional theory calculations, with the use of the natural atomic orbital (NAO) [A.E. Reed et al., J. Chem. Phys. 83 (1985) 735] and Lowdin’s symmetric-orthogonal orbital (LSO). The present NAO- and LSO-EDA schemes are applied to analyses of CO2 and Li 9 + with various basis sets. Numerical results confirm that NAO-EDA exhibits less basis-set dependence, while the conventional results are very sensitive to the adopted basis sets.

Acute respiratory distress syndrome (ARDS) is defined as non-cardiogenic pulmonary edema that develops in individuals with no underlying lung disease. The initial symptoms vary among individuals, but they are followed by common clinical symptoms such as severe dyspnea, tachypnea, and cyanosis. Patients with ARDS show severe hypoxemia, which resists conventional oxygen therapy. They also show reduced pulmonary compliance and the sudden appearance of diffuse shadows on X-ray films of both lungs. The prognosis of this condition is quite poor. We recently encountered a case of ARDS which developed, triggered by aspiration pneumonia, after resection of metastatic tumors of the neck.The patient was a 52-year-old man. On November 28, 1994, he underwent tumor resection and vessel grafting for the treatment of neck tumors that had metastasized from the upper gingiva. On the 4 th postoperative day (December 2), severe dyspnea developed, and diffuse shadows suddenly appeared on radiograms of both lungs. Although routine oxygen therapy was provided after tracheotomy, the patient's ventilation did not improve. He was therefore admitted to the ICU, where the administration of antibiotics to treat and prevent infection and mechanical ventilation were started immediately. The patient's condition deteriorated gradually despite these measures. On December 9, pulsed steroid therapy was started, leading to marked improvement in ventilation and in radiolucency of both lung fields. On December 15, he was weaned from mechanical ventilation and returned to the standard care ward.In the case presented in this paper, ARDS seems to have been induced by misswallowing.The medical staff must be alert when attending patients after oral surgery to note and respond immediately to misswallowing, because the risk of misswallowing is very high after oral surgery.

Little research has been done on supportive needs of cancer patients in acute hospitals in Japan. This study aims to comprehensively assess the unmet supportive needs of hospitalized cancer patients, as well as literacy and utilization of appropriate professional care. All cancer patients (aged 20 to 80 years) who were hospitalized in a university hospital in Tokyo during the designated 3-day period between September 1 and October 31, 2007 were recruited for participation in the study. The M.D. Anderson Symptom Inventory, Brief Cancer-Related Worry Inventory, and Hospital Anxiety and Depression Scale were administered. Patients’ knowledge and use of relevant services were evaluated. The results were compared with those of non-cancer patients in the same treatment settings. A total of 125 cancer patients and 59 non-cancer patients were enrolled. Cancer patients and non-cancer patients equally suffered from physical symptoms (15–26% had severe appetite loss, 18–19% had severe dry mouth, and 16–22% had severe pain); however, psychological distress of cancer patients exceeded that of non-cancer patients (28.0% vs 8.5%; p ≤ 0.05). Severe psychological distress was associated with severe worry about future prospects or interpersonal and social issues and presence of two or more severe symptoms. Two thirds of the patients with severe psychological distress knew about the psychiatric division, but only one third actually sought treatment. Needs related to psychological issues were more prevalent among cancer patients than among non-cancer patients, despite a similar level of physical distress. Special attention should be paid to cancer patients who worry over future prospects or interpersonal and social issues, and those who have two or more severe symptoms.

Energy density analysis was applied to 25 species of Calophyllum coumarins. When the principal component analysis was performed by using energy density as variables, the 25 coumarins were classified into six groups. The first and second principal components were related to the substituent effect and the molecular skeleton, respectively. The molecular skeletons sufficiently influence anti-HIV-1 activities of coumarins rather than the substituents.
