Direct Link Between Cardiac Failure and Global Cerebral Atrophy in a Young Adult: A Case Report on Reduced Cerebral Artery Blood Flow.

BACKGROUND Heart failure is associated with structural brain abnormalities, including atrophy of multiple brain regions. Previous studies have reported brain atrophy in middle-aged patients with systolic heart failure. In this report, we present the case of a 21-year-old woman with idiopathic dilated cardiomyopathy, cardiac failure, and global cerebral atrophy due to reduced cerebral artery blood flow. We also discuss the impact of brain atrophy in this young adult patient with severe heart failure and no risk factors for atherosclerosis. CASE REPORT A 21-year-old woman with dyspnea and leg edema was admitted to our hospital. After several examinations, an endomyocardial biopsy led to a diagnosis of idiopathic dilated cardiomyopathy, and transthoracic ultrasound cardiography revealed that her left ventricular ejection fraction was 36%. One year after the first hospitalization, her heart failure was classified as New York Heart Association Class III. Magnetic resonance imaging showed severe global brain atrophy, and single-photon emission computed tomography combined with brain computed tomography showed reduced blood flow to the entire brain. She had no risk factors for atherosclerosis and no atherosclerotic changes to her brain or carotid arteries, but her neuropsychological and neurological findings indicated more pronounced brain and cognitive dysfunction. CONCLUSIONS This young adult patient with idiopathic dilated cardiomyopathy, cardiac failure, and global cerebral atrophy showed reduced cerebral artery blood flow and cognitive impairment. The findings of this report indicate that low cardiac output may directly cause brain atrophy in patients with systolic heart failure.

An association between cancer type and delirium incidence in Japanese elderly patients: A retrospective longitudinal study.

OBJECTIVE: There is not a known elevated prevalence of delirium in older adult cancer patients. However, it is unknown if the incidence of delirium varies by cancer type among older adult patients. Therefore, this study aimed to examine the association between the incidence of delirium and cancer type among older adult patients using a Japanese hospital-based administrative claims database. METHODS: A total of 76,868 patients over 65 years of age or older, first diagnosed with cancer on an initial date of hospitalization between April 2008 and December 2019, were included in this retrospective longitudinal study. Delirium was defined by the World Health Organization's International Statistical Classification of Diseases and Related Health Problems (ICD-10) codes or antipsychotic medication use. Cox proportional hazard models were performed to estimate the risk of delirium incidence according to 22 cancer types during the one-year hospitalization period. RESULTS: The incidence rates of delirium were 17.1% for men and 15.3% for women. Compared to gastric cancer, the risk of delirium was significantly higher for pancreatic cancer (HR: 1.26, 95% CI: 1.11-1.42 for men; HR: 1.27, 95% CI: 1.11-1.45 for women), leukemia (HR: 1.24, 95% CI: 1.09-1.41 for men; HR: 1.20, 95% CI: 1.03-1.41 for women), and oropharyngeal cancer (HR: 1.30, 95% CI: 1.10-1.54 for men; HR: 1.32; 95% CI: 1.02-1.72 for women) after adjusting for age, initial hospitalization year, antipsychotic medications, and surgery. CONCLUSIONS: As compared to gastric cancer, patients with pancreatic cancer, leukemia, oropharyngeal cancer were found to have a higher risk of developing delirium. Our study findings suggested that the risk of delirium incidence may vary by cancer type.

An Automated Algorithm for Determining Sleep Using Single-Channel Electroencephalography to Detect Delirium: A Prospective Observational Study in Intensive Care Units.

The relationship between polysomnography-based objective sleep and delirium in the intensive care unit (ICU) is inconsistent across studies, suggesting limitations in manually determining the sleep stage of critically ill patients. We objectively measured 24-h sleep using a single-channel electroencephalogram (SleepScope [SS]) and an under-mattress sleep monitor (Nemuri SCAN [NSCAN]), both of which have independent algorithms that automatically determine sleep and wakefulness. Eighteen patients (median age, 68 years) admitted to the ICU after valvular surgery or coronary artery bypass grafting were included, and their sleep time was measured one day after extubation. The median total sleep times (TSTs) measured by SS (TST-SS) and NSCAN were 548 (48−1050) and 1024 (462−1257) min, respectively. Two patients with delirium during the 24-h sleep measurement had very short TST-SS of 48 and 125 min, and the percentage of daytime sleep accounted for >80% in both SS and NSCAN. This preliminary case series showed marked sleep deprivation and increased rates of daytime sleeping in ICU patients with delirium. Although data accuracy from under-mattress sleep monitors is contentious, automated algorithmic sleep/wakefulness determination using a single-channel electroencephalogram may be useful in detecting delirium in ICU patients and could even be superior to polysomnography.

Depressive and anxiety symptoms among Japanese cancer survivors: Japan cancer survivorship research project.

BACKGROUND: This study aimed to clarify predictors of depressive symptoms and anxiety symptoms after cancer diagnosis among Japanese cancer survivors (CSs). METHODS: As part of a Japanese cancer survivorship research project commissioned by the Ministry of Health, Labour and Welfare (MHLW) of Japan, we conducted a web-based nationwide survey of CSs in 2018. We analyzed the risk factors for depressive and anxiety symptoms, as measured by the Hospital Anxiety and Depression Scale Japanese version (HADS). RESULTS: Of 1,234 Japanese CSs, mean score of HADS-depression and HADS-anxiety were 4.08 and 4.78, respectively. At the time of the study, the number of CSs with symptoms of depression and anxiety were 111 (9.0%) and 269 (21.8%), respectively. After multivariable analysis, CSs ≥ 60 years old (reference: ≤ 39 years old, odds ratios (OR): 0.39, 95%CI: 0.17-0.90) and those ≥ 10 years from cancer diagnosis (reference: 0-4 years, OR: 0.55, 95%CI: 0.32-0.96) had lower odds for depressive symptoms. And CSs ≥ 60 years old (reference: ≤ 39 years old, OR: 0.27, 95%CI: 0.15-0.49) and those ≥ 10 years from cancer diagnosis (reference: 0-4 years, OR: 0.62, 95%CI: 0.42-0.90) also had lower odds for anxiety symptoms. CSs who received chemotherapy (OR: 1.56, 95%CI: 1.10-2.20) had higher odds for anxiety symptoms. CONCLUSIONS: Based on manifestation of symptoms, CSs who were younger, closer to the time of cancer diagnosis, had advanced-staged cancer, or received chemotherapy may be at higher risk for depressive or anxiety symptoms. Those CSs who have higher risk for depression and anxiety symptoms, should be followed-up more carefully for better cancer survivorship, by medical professionals, companies, and society.

Predictors of resignation and sick leave after cancer diagnosis among Japanese breast cancer survivors: a cross-sectional study.

BACKGROUND: In Japan, 55.5% of breast cancer survivors (BCSs) are of working age, so various perspectives regarding return to work (RTW) after cancer diagnosis need to be considered. Therefore, this study aimed to clarify the risk factors for resignation and taking sick leave (SL) among BCSs in continued employment at the time of diagnosis. METHODS: A web-based retrospective cross-sectional survey was conducted on BCSs using data from a 2018 Japanese national research project (Endo-Han) commissioned by the Ministry of Health, Labour and Welfare of Japan. The subjects were women aged 18-69 years who had been diagnosed with breast cancer for the first time at least 1 year previously. The risk factors for resignation and taking SL after breast cancer diagnosis, including age at diagnosis, education level, cancer stage, surgery, chemotherapy, radiotherapy, employment status, and occupational type, were then analyzed using a logistic regression model. RESULTS: In total, 40 (14.9%) of 269 BCSs quit their jobs at least 1 year after being diagnosed with breast cancer. The results of the multivariable analysis indicated that lower education level (odds ratio [OR]: 3.802; 95% confidence interval [CI]: 1.233-11.729), taking SL (OR: 2.514; 95%CI: 1.202-5.261), and younger age at diagnosis (OR: 0.470; 95%CI: 0.221-0.998) were predictors of resignation. Of 229 patients who continued working, SL was taken by 72 (31.4%). In addition, undergoing surgery was found to be a predictor of taking SL (OR: 8.311; 95%CI: 1.007-68.621). CONCLUSIONS: In total, 40 (14.9%) of 269 BCSs quit their jobs at least 1 year after being diagnosed with breast cancer. The results of this study indicated that younger age, lower education level, and taking SL were predictors of resignation after breast cancer diagnosis.

Current state of hypnotic use disorders: Results of a survey using the Japanese version of Benzodiazepine Dependence Self-Report Questionnaire.

AIMS: Benzodiazepine receptor agonists (BZ-RAs) are frequently prescribed to treat insomnia; however, their long-term use is not recommended. To introduce an appropriate pharmaco-therapy, the current state and background factors of BZ-RAs' dependence must be elucidated. In this study, we developed a Japanese version of the Benzodiazepine Dependence Self-Report Questionnaire (Bendep-SRQ-J) and conducted a study of BZ-RAs' use disorder. METHODS: The Bendep-SRQ-J was created with permission from the original developer. Subjects were inpatients and outpatients receiving BZ-RAs between 2012 and 2013. Clinical data collected were Bendep-SRQ-J scores, sleep disorders for which BZ-RAs were prescribed, physical comorbidities, psychotropic drugs, and lifestyle factors. Logistic analysis was performed to extract factors associated with severe symptoms. RESULTS: Of the 707 patients prescribed BZ-RAs, 324 had voluntarily tapered or discontinued their drugs. Logistic analysis showed that the total number of drugs administered in the last 6 months correlated with both worsening of symptoms or conditions. This was more notable among younger patients, and the proportion of patients with severe symptoms or conditions increased with the increasing number of drugs. CONCLUSION: Using the Bendep-SRQ-J, we elucidated the current state of BZ-RA dependence. Nearly half of the patients were non-compliant. The proportion of patients with severe symptoms or disease conditions increased with the increase in the number of drugs administered. These findings highlight the need for clinicians to be aware of the likelihood of benzodiazepine dependence, especially in young patients and patients prescribed multiple hypnotics.

Prevalence and Associated Factors of Nocturnal Eating Behavior and Sleep-Related Eating Disorder-Like Behavior in Japanese Young Adults: Results of an Internet Survey Using Munich Parasomnia Screening.

Nocturnal (night) eating syndrome and sleep-related eating disorder have common characteristics, but are considered to differ in their level of consciousness during eating behavior and recallability. To date, there have been no large population-based studies determining their similarities and differences. We conducted a cross-sectional web-based survey for Japanese young adults aged 19-25 years to identify factors associated with nocturnal eating behavior and sleep-related eating disorder-like behavior using Munich Parasomnia Screening and logistic regression. Of the 3347 participants, 160 (4.8%) reported experiencing nocturnal eating behavior and 73 (2.2%) reported experiencing sleep-related eating disorder-like behavior. Smoking (p < 0.05), use of hypnotic medications (p < 0.01), and previous and/or current sleepwalking (p < 0.001) were associated with both nocturnal eating behavior and sleep-related eating disorder-like behavior. A delayed sleep-wake schedule (p < 0.05) and sleep disturbance (p < 0.01) were associated with nocturnal eating behavior but not with sleep-related eating disorder-like behavior. Both nocturnal eating behavior and sleep-related eating disorder-like behavior had features consistent with eating disorders or parasomnias. Nocturnal eating behavior but not sleep-related eating disorder-like behavior was characterized by a sleep-awake phase delay, perhaps representing an underlying pathophysiology of nocturnal eating syndrome.

Predictors of post-cancer diagnosis resignation among Japanese cancer survivors.

PURPOSE: In Japan, due to the increased incidence of cancer among the working population, it has become more important to support employees to achieve a balance between cancer treatment and work. This study aimed to clarify the predictors of resigning from employment after being diagnosed with cancer (post-cancer diagnosis [PCD] resignation) among Japanese employees. METHODS: As part of a Japanese national research project (Endo-Han), the investigators conducted a web-based survey of cancer survivors (CSs) in 2017. The investigators analyzed the risk factors for PCD resignation using a logistic regression model, including age at diagnosis, sex, cancer type, cancer stage, year of diagnosis, whether the patient held a managerial role, type of employment, and company size. RESULTS: Of 750 employed Japanese CSs, 93 (12.4%) resigned from their jobs. The non-managers resigned more often (14.6%) than the managers (7.6%) (p = 0.007). The temporary workers exhibited the highest PCD resignation rates (22.2%), while the PCD resignation rates of the self-employed workers and permanent workers were 15.2% and 7.6%, respectively (p < 0.001). As the result of multivariate analysis, being female (odds ratio [OR], 3.67; 95%CI, 1.71-7.87), having hematological cancer (OR, 4.23; 95%CI, 1.37-13.04), having advanced cancer (OR, 2.48; 95%CI, 1.52-4.03), and being a temporary worker (OR, 2.51; 95%CI, 1.40-4.50) were identified as predictors of PCD resignation. CONCLUSIONS: In total, 12.4% of Japanese employees quit their jobs after being diagnosed with cancer. Being female or a temporary worker and having advanced cancer were identified as predictors of PCD resignation. Regarding cancer type, hematological cancer was most strongly associated with PCD resignation. IMPLICATION OF CANCER SURVIVORS: CSs who are females and temporary workers and have advanced cancer should be followed-up more carefully after cancer diagnosis for their work sustainability, by medical professionals, companies, and society.

Detailed assessment and risk factor analysis of corticosteroid-induced psychiatric disorders in pediatric, adolescent, and young adult patients undergoing induction or consolidation therapy for hematologic malignancy.

BACKGROUND: Corticosteroid-induced psychiatric disorders (CIPDs) represent an adverse effect that can cause severe emotional and behavioral problems. The aim of the present study was to assess the incidence and risk factors of CIPDs. METHODS: A retrospective analysis of 92 pediatric and young adult patients with hematologic malignancies was conducted. RESULTS: The incidence of CIPDs in patients receiving a treatment regimen with prednisolone or dexamethasone was 64.9% and 77.5%, respectively, both of which were significantly higher than that in patients not receiving corticosteroids. Independent risk factors and adjusted odds ratios (95% confidence intervals) related to severe CIPD were 2.15 (1.11-4.18) for dexamethasone (using prednisolone as the reference) and 0.81 (0.75-0.87) for age, suggesting that the odds increase with decreasing age. Frequently observed symptoms, respectively in terms of behavioral and emotional problems were defiance, crying, psychomotor excitement, dysphoria, irritability, and depression. To our knowledge, this is the first report to mention the risk factors and characteristics for clinical symptoms of CIPDs during the developmental process. CONCLUSIONS: Healthcare professionals should predict and prepare for psychiatric adverse events prior to chemotherapy in the clinical settings, especially in patients in younger age and receiving a treatment regimen with dexamethasone.

No Evidence for Particular Association Between HLA-Haploidentical Hematopoietic Stem Cell Transplantation and Psychological Distress.

BACKGROUND: The psychological distress experienced by patients scheduled for hematopoietic stem cell transplantation (HSCT) is of clinical concern. However, distress experienced by patients scheduled for HLA-haploidentical HSCT vs that of patients scheduled for other types of matched HSCT is unknown. We conducted a retrospective study to clarify whether the type of HSCT influences the appearance of psychological distress in patients anticipating HSCT. METHODS: One hundred fifty-seven patients who had undergone any of 4 types of HSCT at Tokyo Metropolitan Komagome Hospital between October 2013 and September 2016 and had completed the Profile of Mood States (POMS) questionnaire within 2 weeks before the procedure were included. We computed T-scores for the tension-anxiety (TA) and depression (D) subscales, took scores ≥ 60 to represent mood disturbance of clinical concern, and examined scores and other clinical variables in relation to each procedure. RESULTS: Twenty-two (14.0%) patients had a POMS-TA score ≥ 60, and 26 (16.6%) had a POMS-D score ≥ 60. The numbers of POMS-TA and POMS-D scores ≥ 60 did not differ significantly with respect to age, sex, leukemia type, number of previous transplants, disease status, comorbidity index, or transplant type. A multivariate logistic regression analysis confirmed the absence of an influence of the type of HSCT on the incidence of POMS-TA or POMS-D scores ≥60. CONCLUSION: Attention should be paid to the matter of psychological distress in patients with leukemia who will be treated by HSCT, even HLA-haploidentical HSCT. Such patients need psychological support, especially during the waiting period immediately prior to the transplantation procedure.

Patient Health Questionnaire-2 Screening for Depressive Symptoms in Japanese Outpatients with Heart Failure.

Objective Depression is common in patients with heart failure (HF) and is a possible risk factor for adverse outcomes. The aim of this study was to determine the prevalence of depression assessed by the 2-item Patient Health Questionnaire (PHQ-2) and the effect of depression on outcomes in Japanese outpatients with HF. Methods This sub-analysis of a prospective observational study assessed 976 patients with HF (mean age 66±13 years; 26.7% female; 42.7% with an ischemic etiology). Depression was defined as a PHQ-2 score ≥3. The main composite outcome was death from any cause or hospitalization due to worsening HF. PHQ-2 items were extracted from the PHQ-9 results. To evaluate the association of PHQ-2 scores with outcomes, Cox proportional hazards models were evaluated. Results Fifty-seven (5.8%) patients were diagnosed with depression. During a median follow-up of 21 months, the incidence rates for death from any cause and hospitalization due to worsening HF in patients with and without depression were 2.2 vs. 0.9 per 100 person-years and 6.7 vs. 1.6, p<0.001, respectively. There was a higher incidence of the main outcome in patients with depression than in those without depression (p<0.001). After adjustment for conventional risk factors, depression (PHQ-2 ≥3) was an independent predictor of the main outcome (hazard ratio 2.41, 95% confidence interval 1.14-4.67, p=0.022), and a score for item 1 of the PHQ-2 (loss of interest or pleasure) ≥2 was also an independent risk factor (hazard ratio 3.57, 95% confidence interval 1.85-6.46, p<0.001). Conclusion Depression as assessed by the PHQ-2 was identified in 5.8% of Japanese outpatients with HF and was associated with outcomes.

Accuracy of oncologist assessments of psychiatric problems in cancer inpatients.

OBJECTIVE: Our objective was to examine the accuracy of non-psychiatrist assessments of psychiatric problems in cancer patients. METHOD: We conducted a retrospective chart review of cancer patients who were admitted and referred to the consultation-liaison (C-L) team between January of 2011 and December of 2012. The agreement between non-psychiatrist assessments and final diagnoses by attending C-L psychiatrists was estimated for every category of referral assessment using codes from the International Classification of Mental and Behavioral Disorders (10th revision). The data were obtained from the consultation records of 240 cancer inpatients who were referred to the C-L service at a tertiary care center in Tokyo. RESULTS: The agreement ratio between referring oncologists and psychiatrists differed according to the evaluation categories. The degrees of agreement for the categories of "delirious," "depressive," "dyssomnia," "anxious," "demented," "psychotic," and "other" were 0.87, 0.43, 0.51, 0.50, 0.27, 0.55, and 0.57, respectively. The agreement for all patients was 0.65. Significant differences were observed among seven categories (chi-squared value = 42.454 at p < 0.001 and df = 6). The analysis of means for proportions showed that the degree of agreement for the "delirious" category was significantly higher and that that for the "depressive" category was lower than that for all patients, while for the "demented" category it was close to the lower decision limit but barely significant. One half of the 20 cases who were referred as depressive were diagnosed with delirium, with one quarter of those having continuously impaired consciousness. Some 7 of the 11 cases who were referred as demented were diagnosed as having delirium. SIGNIFICANCE OF RESULTS: The accuracy of non-psychiatrist assessments for psychiatric problems in cancer patients differs by presumed diagnosis. Oncologists should consider unrecognized delirium in cancer inpatients who appear depressed or demented.

Sensitivity and specificity of the Confusion Assessment Method for the Intensive Care Unit (CAM-ICU) and the Intensive Care Delirium Screening Checklist (ICDSC) for detecting post-cardiac surgery delirium: A single-center study in Japan.

OBJECTIVE: To compare the Confusion Assessment Method for the Intensive Care Unit (CAM-ICU) and the Intensive Care Delirium Screening Checklist (ICDSC) for detecting post-cardiac surgery delirium. BACKGROUND: These tools have not been tested in a specialized cardio-surgical ICU. METHODS: Sensitivities and specificities of each tool were assessed in a cardio-surgical ICU in Japan by two trained nurses independently. Results were compared with delirium diagnosed by psychiatrists using the Diagnostic and Statistical Manual of Mental Disorders, 4th Edition, Text Revision. RESULTS: There were 110 daily, paired assessments in 31 patients. The CAM-ICU showed 38% sensitivity and 100% specificity for both nurses. All 20 false-negative cases resulted from high scores in the auditory attention screening in CAM-ICU. The ICDSC showed 97% and 94% sensitivity, and 97% and 91% specificity for the two nurses (cutoff ≥4). CONCLUSION: In a Japanese cardio-surgical ICU, the ICDSC had a higher sensitivity than the CAM-ICU.

Neurocognitive impairment in corticosteroid-naive patients with active systemic lupus erythematosus: a prospective study.

OBJECTIVE: Neurocognitive impairment (NCI) has been intensively studied in patients with systemic lupus erythematosus (SLE). However, those studies have mostly included patients who were treated with corticosteroids, which may itself induce NCI. We investigated NCI in corticosteroid-naive people with SLE who did not exhibit any overt neuropsychiatric manifestations. METHODS: Forty-three inpatients with SLE who had no current or past neuropsychiatric history participated in the study. Patients and 30 healthy control subjects with similar demographic characteristics were given a 1-h battery of neuropsychological tests. NCI was defined as scores at least 2 SD below the mean of the healthy control group on at least 2 of the 7 neurocognitive domains. Results of clinical, laboratory, and neurologic tests were compared regarding the presence of NCI. RESULTS: NCI was identified in 12 patients (27.9%) with SLE and in 2 control subjects (6.7%). Patients with SLE showed a significant impairment compared with controls on tasks assessing immediate recall, complex attention/executive function, and psychomotor speed. We identified psychomotor speed (Digit Symbol Substitution Test) as the factor that best differentiated the 2 groups. Further, we identified the score of the SLE Disease Activity Index 2000 as an independent risk factor for NCI in patients with SLE. CONCLUSION: We conclude that reduced psychomotor speed is an SLE-specific pattern of NCI. Verbal-memory deficits that have been reported in patients with SLE were not evident among patients who were corticosteroid-naive. Our results indicate that impaired psychomotor speed may be added to the symptoms of early SLE.

Risk factors for alcohol relapse after liver transplantation for alcoholic cirrhosis in Japan.

Alcoholic liver cirrhosis (ALC) is an established indication for liver transplantation (LT). Most LT procedures in Japan are living donor liver transplantation (LDLT) because of an extreme shortage of deceased donors. Social circumstances enabling LDLT could be favorable for preventing relapse. The aims of this retrospective study were to analyze the outcomes of LDLT for ALC and to evaluate risk factors for relapse in this cohort. One hundred ninety-five subjects underwent LT [LDLT (n = 187), deceased donor LT (n = 5), or domino LT (n = 3)] for ALC in Japan from November 1997 to December 2011. Risk factors for alcohol relapse and the impact of relapse on outcomes were analyzed for 140 patients after the exclusion of 26 patients who died in the hospital and 29 patients without information about alcohol relapse. The incidence of alcohol consumption after LT was 22.9%. The risk factors for patient survival were a donor age ≥ 50 years (P < 0.01) and a Model for End-Stage Liver Disease score ≥ 19 (P = 0.03). The 10-year patient survival rates were 21.9% and 73.8% for patients who had relapsed and patients who had not relapsed 18 months after LT, respectively (P = 0.01). The relapse rates were 50.0%, 34.5%, 13.3%, 19.7%, and 14.3% for patients who had received livers from parents, siblings, spouses, sons/daughters, and deceased or domino donors, respectively. A history of treatment for psychological diseases other than alcoholism before LT was a significant indicator for the risk of recidivism (P = 0.02), and noncompliance with clinic visits after LT and smoking after transplantation were promising indicators for the risk of recidivism (P = 0.06, and P = 0.05, respectively). Preoperative alcohol consumption was not a risk factor. In conclusion, rather than selecting patients on the basis of preoperative alcohol use, we should provide sociomedical support to improve adherence after LT for ALC in Japan.

Antipsychotics for delirium in the general hospital setting in consecutive 2453 inpatients: a prospective observational study.

OBJECTIVE: Attention to risk of antipsychotics for older patients with delirium has been paid. A clinical question was whether risk of antipsychotics for older patients with delirium would exceed efficacy of those even in the general hospital setting. METHODS: A prospective observational study proceeded over a 1-year period at 33 general hospitals, where at least one psychiatrist worked full time. Subjects were patients who developed delirium during their admission due to acute somatic diseases or surgery, and who received antipsychotics for delirium. The primary outcome was rates and kinds of serious adverse events. RESULTS: Among 2834 patients who developed delirium, 2453 patients received antipsychotics, such as risperidone (34%), quetiapine (32%), and parenteral haloperidol (20%), for delirium. Out of 2453 patients, 22 serious adverse events (0.9%) were reported. Aspiration pneumonia was the most frequent (17 patients, 0.7%), followed by cardiovascular events (4 patients, 0.2%) and venous thromboembolism (1 patient, 0.0%). There was no patient with a fracture or intracranial injury due to a fall. No one died because of antipsychotic side effects. The mean Clinical Global Impressions-Improvement Scale score was 2.02 (SD 1.09). Delirium was resolved within 1 week in more than half of the patients (54%). CONCLUSIONS: In the general hospital setting under management including fine dosage adjustment and early detection of side effects, risk of antipsychotics for older patients with delirium might be low, in contrast to antipsychotics for dementia in the nursing home or outpatient settings. A point may be not how to avoid using antipsychotics but how to monitor their risk.

Nurses' recognition of the mental state of cancer patients and their own stress management - a study of Japanese cancer-care nurses.

OBJECTIVE: The primary aim of this study was to describe Japanese oncology nurses' self-reported ability to assess and care for cancer patients' mental health. A secondary aim was to describe nurses' self-reported stress levels and need for stress management related to caring for oncology patients. METHODS: This cross-sectional questionnaire study was conducted from September to November 2010 among cancer-care nurses participating in mental healthcare training. The questionnaire asked about assessment of patient anxiety, depression, delirium, anger, and acceptance, and included four statements about work-related stress. A 4-point Likert scale was used for responses. RESULTS: The 88 participants (86 women) ranged in age from the 20s to the 50s, with the greatest number in their 30s (47.2%, n=42). More than 50% of nurses were very concerned about assessing cancer patient anxiety and depression; approximately 20% were extremely concerned about caring for depression and anger in patients. Overall, 83.2% (n=74) of cancer-care nurses felt distressed over their occupation, only 19.1% (n=17) stated that they were controlling their stress, and over half indicated a need for stress-management programs. CONCLUSIONS: Nurses perceived that assessments of and care for the mental state of cancer patients were inadequate. Cancer-care nurses need training in assessing and caring for the mental state of cancer patients, as well as stress management training programs for themselves.

Anti-NR2A antibody as a predictor for neuropsychiatric systemic lupus erythematosus.

OBJECTIVE: The aim of this study is to establish a detection method for anti-N-methyl-d-aspartate receptor subunit 2A (NR2A) antibody and to evaluate the relationship between anti-NR2A antibody and various organ involvement in SLE. METHODS: Serum anti-NR2A antibody was measured by ELISA using a peptide with a core of either DWEYS or DWDYS as autoantigen. Additionally, clinical characteristics were compared between 27 anti-NR2A antibody-positive (P group) and 80 antibody-negative (N group) SLE patients using DWDYS peptide. RESULTS: The optical density (OD) values of anti-NR2A antibody using DWDYS and DWEYS peptides correlated significantly (r = 0.94, P < 0.0001). The median OD value was significantly higher (P < 0.0001) with DWDYS. Additionally, the SLEDAI was significantly higher (P = 0.023) in the P group. The frequency of neuropsychiatric SLE (NPSLE) was significantly higher (P = 0.0002) in the P group, although the frequencies of serositis and nephritis were not statistically significant. Significant correlations were found between anti-NR2A antibody and leucocyte count (r(s) = -0.31, P = 0.001) and haemoglobin (r(s) = -0.42, P < 0.0001), although no correlation was found between anti-NR2A antibody and the titre of anti-dsDNA antibody. NPSLE was the most significant independent variable (P = 0.0008) associated with anti-NR2A antibody positivity, as estimated by multiple linear regression analysis. CONCLUSION: Serum anti-NR2A antibody can be associated with the complication of NPSLE and may indicate the involvement of non-nervous tissue. The use of peptides that include DWDYS is preferable to detect anti-NR2A antibody in ELISA.
