Effect of intermittent subchronic MK-801 administration on dopamine synthesis capacity and responsiveness in the prefrontal cortex.

AIM: The therapeutic potential of N-methyl-D-aspartate glutamate receptor (NMDAR) antagonists, particularly ketamine, in mood disorders, is linked to their modulation of dopamine dynamics in the medial prefrontal cortex (mPFC). However, conflicting effects of distinct NMDAR antagonists, like ketamine and phencyclidine, on mPFC dopamine levels stem from variances in their receptor affinity profiles. This study investigates the impact of intermittent subchronic administration of an NMDAR antagonist on dopamine synthesis capacity and responsiveness within the mPFC, focusing on Dizocilpine (MK-801), a highly selective NMDAR antagonist. METHODS: In vivo microdialysis and high-performance liquid chromatography assessed extracellular dopamine levels in the mPFC following subchronic MK-801 treatment. Locomotor activity was measured using a computed video tracking system. RESULTS: Intermittent subchronic MK-801 administration, followed by a 24-h withdrawal, preserved both dopamine synthesis capacity and responsiveness to MK-801 challenge in the mPFC. However, altered locomotor activity was observed, deviating from previous findings indicating impaired dopamine synthesis and responsiveness in the mPFC with twice-daily subchronic NMDAR antagonist treatment. CONCLUSION: These findings offer crucial biochemical insights into the diverse impacts of NMDAR antagonists on dopamine dynamics and the distinct therapeutic mechanisms associated with ketamine in depression treatment. However, further investigation is imperative to pinpoint potential inconsistencies stemming from variances in drug type, dosage, or administration frequency.

Coexistence of periodic limb movements during sleep with restless legs syndrome and its association with hypertension in Japanese patients.

BACKGROUND: Caucasian patients with restless legs syndrome (RLS) frequently exhibit periodic limb movements during sleep (PLMS), which may increase the risk of hypertension. We evaluated the positivity rate of PLMS and factors associated with positivity in Japanese patients with RLS, and tested whether the complications of PLMS are associated with the presence of hypertension. METHODS: We retrospectively investigated polysomnographic data and the presence or absence of hypertension in patients with RLS. Patients with systolic blood pressure ≥140 mmHg or diastolic blood pressure ≥90 mmHg or those taking antihypertensive medication were categorized as the group with hypertension. RESULTS: Among 468 patients, 200 (42.7%) had periodic limb movement index (PLMI) values ≥ 15/h and 108 (23.1%) met the criteria of positivity for hypertension. Multiple logistic regression analysis revealed that only higher age was significantly associated with PLMI values ≥ 15/h. Multiple linear regression analyses of factors associated with an increased PLMI also showed that increased PLMI was significantly correlated with higher age and male sex, but not with the international restless legs scale scores. Multiple logistic regression analysis also revealed that higher age and body mass index, not PLMI values ≥ 15/h, were significantly associated with the presence of hypertension. CONCLUSION: The PLMS-positivity rate may be lower in Japanese patients with RLS than in Caucasian patients, and it increases with age and male sex, but not with the severity of the disorder. Furthermore, PLMS complications were not associated with the risk of hypertension in Japanese patients with RLS.

Effects of chronic haloperidol treatment on the expression of fear memory and fear memory extinction in the cued fear-conditioned rats.

AIM: Impairments in emotional memory are frequently observed in several mental disorders, highlighting their significance as potential therapeutic targets. Recent research on the cued fear conditioning model has elucidated the neural circuits involved in fear memory processing. However, contradictory findings have been reported concerning the role of dopamine and the impact of dopamine D2 receptor (D2R) antagonists. There is notably limited knowledge regarding the clinical utility of chronic D2R antagonist treatments. This study aimed to uncover how such treatments affect fear memory processing. METHODS: We utilized a cued fear conditioning rat model and conducted chronic haloperidol treatment for 14 days. Subsequently, to investigate the effect of chronic haloperidol treatment on fear-conditioned memory expression and extinction, we observed freezing behavior under exposure to a conditioned stimulus for 14 days. RESULTS: Chronic haloperidol treatment suppressed freezing time on the fear memory expression. In contrast, a single haloperidol administration enhanced the freezing time on fear memory expression and delayed extinction. CONCLUSION: The results of this study suggest that chronic administration of antipsychotic drugs affects fear memory processing differently from single-dose administration. This indicates that the effects of chronic D2R antagonist treatment are distinct from the nonspecific effects of the drugs. This study provides fundamental insights that may contribute to our understanding of therapeutic mechanisms for fear memory disorders related to D2R in the future.

Association of the Stanford Integrated Psychosocial Assessment for Transplant and 1-Year Outcome of Living Kidney Transplantation in Japan.

BACKGROUND: Because most kidney transplantations in Japan are performed on the basis of living donors, after-transplant outcomes should achieve optimum results, overcoming participants' possible reduced adherence. OBJECTIVE: To investigate the association between the Japanese version of the Stanford Integrated Psychosocial Assessment for Transplantation (SIPAT-J) and outcomes, 1 year after the patient's living kidney transplant (LKT). METHODS: The prospective cohort study was undertaken at Tokyo Women's Medical University Hospital from January 2020 to July 2021, with a 1-year follow-up period. The SIPAT-J assesses 18 psychosocial risk factors: (1) Patient's Readiness Level and Illness Management (SIPAT A), (2) Social Support System Level of Readiness (SIPAT B), (3) Psychological Stability and Psychopathology (SIPAT C), and (4) Lifestyle and Effect of Substance Use (SIPAT D). The evaluators, a psychiatrist and 3 clinical psychologists, conducted an independent, blinded application of the SIPAT-J using participants' medical records. The study focused on physical composite outcomes, psychiatric outcomes, and nonadherent behaviors. RESULTS: The participants were 173 LKT recipients (median age [interquartile range], 51 [38-59]); 67.1% were male and 67.1% were employed. The median (interquartile range) SIPAT scores were SIPAT A [7 (5-9)], SIPAT B [7 (5-9)], SIPAT C [2 (0-4)], SIPAT D [3 (3-4)], and SIPAT total [20 (16-23)]. The physical composite outcome was 25 (14.5%), psychiatric outcome 9 (5.2%), and nonadherent behavior 17 (9.8%). SIPAT C (odds ratio = 1.34, 95% confidence interval = 1.06-1.72, P = 0.02) was significantly associated with the psychiatric outcome. SIPAT B (odds ratio = 1.49, 95% confidence interval = 1.12-1.98, P = 0.01) and SIPAT total (odds ratio = 1.13, 95% confidence interval = 1.03-1.24, P = 0.01) were significantly associated with nonadherent behaviors. There was no significant association between the SIPAT and physical composite outcomes. CONCLUSION: This study is the first to examine the association between SIPAT and physical and psychiatric outcomes 1 year after LKT, controlling for follow-up periods and factors other than SIPAT. Comprehensive psychosocial assessment before LKT and early identification of factors that may negatively affect transplant success can allow targeted interventions to be implemented and increase the likelihood of favorable recipient outcomes.

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.

Family functioning before kidney transplantation from living-related donors: Perspectives of donors and recipients in Japan.

INTRODUCTION: In Japan, approximately 90% of kidney transplantations involve living donors who are relatives. Selection of a living donor from potential family member donors could affect the entire family. However, reports focusing on preliving-related kidney transplant (LRKT) family functioning are lacking. Family functioning comprises ways that family members communicate and cooperate with each other. The Family Assessment Device (FAD) was used to measure family functioning from the perspective of donors and recipients just prior to LRKT. METHOD: A total of 122 donor-recipient pairs (244 participants in total) who planned to have LRKT were recruited consecutively from July 2020 to July 2021 and included in the analysis. RESULTS: There was no significant difference in FAD scores between donors and recipients, with approximately 20% of both groups reporting poor family functioning. Differences in family functioning according to types of relatives were shown in recipients. The rate of poor family functioning was significantly lower in the spouse group than in the parent-to-child group (recipient: 6.6%, 29.3%; donor: 8.2%, 34.1%, respectively). However, agreement regarding good or poor family functioning assessment was high in the parent-to-child pairs and low in the spouse pairs. DISCUSSION: Most LRKT donors and recipients reported good family functioning; however, some perceived poor family functioning. Evaluations by donors did not always align with that of recipients, especially among spouse pairs. It is important to treat them as independent entities. Preoperative assessment to connect them with appropriate support can enhance recovery after LRKT. (PsycInfo Database Record (c) 2023 APA, all rights reserved).

Characterization of the stanford integrated psychosocial assessment for transplant for heart, liver, and kidney transplant candidates in Japan.

BACKGROUND: The Stanford Integrated Psychosocial Assessment for Transplantation (SIPAT) is a comprehensive psychosocial assessment proven useful for predicting the outcomes of organ transplantation that is expected to be useful in Japan. However, the characteristics of organ-specific SIPAT scores for organ transplant recipient candidates in Japan are unclear and, to date, the SIPAT has not been properly utilized in clinical practice. The purpose of this study was to present basic data that can be used to establish the relation between SIPAT scores and post-transplantation psychosocial outcomes as well as organ-specific outcomes. METHODS: This study included 167 transplant recipient candidates (25 heart, 71 liver, and 71 kidney) who completed a semi-structured interview based on the Japanese version of SIPAT (SIPAT-J) prior to transplantation. The differences between organs in terms of SIPAT scores and differences in SIPAT scores based on demographic data were comparatively analyzed. RESULTS: The total SIPAT scores were higher for liver recipient candidates than for heart recipient candidates (P = .019). Regarding the subscales, SIPAT B (social support system) scores were higher for liver and kidney recipient candidates than for heart recipient candidates (P = .021), whereas SIPAT C (psychological stability and psychopathology) scores were higher for liver recipient candidates than for kidney recipient candidates (P = .002). Recipient candidates with a history of psychiatric treatment and those who were unemployed had higher SIPAT scores, regardless of the transplant organ, than recipient candidates without a history of psychiatric treatment and those who were employed (P < .001, P = .016, respectively). CONCLUSIONS: There were notable differences in the total SIPAT-J and subscale scores among the liver, heart, and kidney recipient candidates. Each organ was associated with specific psychosocial issues that should be addressed before transplantation. Interventions such as information provision and patient education based on SIPAT assessment results for each organ may improve recipient post-transplant outcomes.

Comorbid psychiatric disorders and long-term survival after liver transplantation in transplant facilities with a psychiatric consultation-liaison team: a multicenter retrospective study.

OBJECTIVE: Comorbid psychiatric disorders negatively affect the survival rate of patients with some physical disorders. In liver transplant recipients, various psychiatric disorders have been identified as worsening prognosis. However, little is known about how the presence of any comorbid (overall) disorders affect the survival rate of transplant recipients. In this study, we examined the effect of overall comorbid psychiatric disorders on survival rate in liver transplant recipients. METHODS: A total of 1006 recipients who underwent liver transplantation between September 1997 and July 2017 across eight transplant facilities with a psychiatric consultation-liaison team were identified consecutively. Recipients were categorized into those with comorbid psychiatric disorders and those without comorbid psychiatric disorders. In the comorbid psychiatric disorder group, psychiatric disorder diagnosis and time of diagnosis were investigated retrospectively. RESULTS: Of the 1006 recipients, 294 (29.2%) had comorbid psychiatric disorders. Comorbid psychiatric disorders in the 1006 recipients were insomnia (N = 107, 10.6%), delirium (N = 103, 10.2%), major depressive disorder (N = 41, 4.1%), adjustment disorder (N = 19, 1.9%), anxiety disorder (N = 17, 1.7%), intellectual disability (N = 11, 1.1%), autism spectrum disorder (N = 7, 0.7%), somatic symptom disorder (N = 4, 0.4%) schizophrenia (N = 4, 0.4%), substance use disorder (N = 24, 2.4%) and personality disorder (N = 2, 0.2%). The most common time of psychiatric disorder diagnosis was within the first 3 months after liver transplantation (51.6%). The final mortality in patients with comorbid psychiatric disorder diagnosis during the five periods (pretransplant, transplant to 3 months, months to 1 year, 1 to 3 years, and over 3 years posttransplant) was 16.2%, 18.8%, 39.1%, 28.6%, and 16.2% respectively, and there were no significant differences between the five periods (χ2 = 8.05, df = 4, p = 0.09). Overall comorbid psychiatric disorders were significantly associated with shorter survival time (log-rank test: p = 0.01, hazard ratio: 1.59 [95% confidence interval: 1.14-2.21], survival rate at the endpoint [%]: 62.0 vs. 83.3). However, after adjusting for confounding variables using Cox proportional hazards regression, there was no significant effect of overall comorbid psychiatric disorders on prognosis. CONCLUSION: Comorbid psychiatric disorders did not affect the survival rate of liver transplant recipients in this study.

Adherence to CPAP in summer to autumn predicts self-reported common cold symptoms in patients with obstructive sleep apnea in winter: A prospective observational study.

OBJECTIVE: We conducted a prospective observational study to determine the relationship between adherence to continuous positive airway pressure (CPAP) and susceptibility to the common cold in moderate-to-severe obstructive sleep apnea (OSA) patients. METHODS: We prospectively investigated the number of days with common cold symptoms from November 2019 to February 2020. The rate of CPAP use for 4 h/night in the preceding four months (July to October 2019) was used as a measure of CPAP adherence. Multiple generalized linear models were used to evaluate the association to days of common cold symptoms after controlling for demographic variables, habitual short sleep duration, and insomnia severity. RESULTS: We included 123 outpatients (median age 63 years) with moderate-to-severe OSA treated with CPAP. In the multivariate generalized linear model, better CPAP adherence was independently significantly associated with days with fewer common cold symptoms (ß = -0.248, P = 0.031); meanwhile, the severity of insomnia and habitual short sleep duration was not significantly associated with it. Subgroup analyses revealed that the association between CPAP adherence and days with common cold symptoms was also significant in young to middle-aged (<65 years) participants (ß = -0.407, P = 0.005). In contrast, the association was negligible in older (≥65 years) participants. CONCLUSIONS: CPAP adherence may be protective against viral infections in patients with moderate-to-severe OSA. This effect appears to be more pronounced in young to middle-aged patients with OSA.

Improvement of obsessive-compulsive disorder after pallidothalamic tractotomy for cervical dystonia.

A 30-year-old woman with tardive dystonia in the cervical region from long-term antipsychotic meds was treated with radiofrequency ablation of the right pallidothalamic tract in the fields of Forel. The patient showed improvement in both cervical dystonia and obsessive-compulsive disorder after the procedure, with 77.4% improvement in cervical dystonia and 86.7% improvement in obsessive-compulsive disorder. Although the treatment site in this case was intended to treat cervical dystonia, the lesion was located in the optimal stimulation network for both obsessive-compulsive disorder and cervical dystonia, suggesting that neuromodulation of this region could potentially treat both simultaneously.

Depression and health-related quality of life in adolescents and young adults with childhood-onset end-stage kidney disease: a multicenter study in Japan.

BACKGROUND: Patient survival and physical outcomes among children with end-stage kidney disease (ESKD) have significantly improved, and recent research has focused on long-term depression symptoms and health-related quality of life (HRQOL). However, no studies have been conducted among adolescents and young adults with childhood-onset ESKD in Japan. METHODS: This multicenter study included 45 adolescents and young adults aged 16-39 years who developed ESKD at age < 20 years. Depression symptoms were measured using the Beck Depression Inventory (BDI)-II. The Short Form-36 Health Survey (SF-36) was used to assess HRQOL. Factors associated with depression and HRQOL were analyzed. RESULTS: Depression (BDI-II score ≥ 14) was observed in 13 (29%) patients. Patient's SF-36 physical component summary (PCS) and mental component summary (MCS) scores were comparable with those for the general population. Lower estimated glomerular filtration rate, higher BDI-II scores, and lower body mass index were associated with lower PCS scores. BDI-II scores were negatively correlated with MCS scores. We observed a trend that unemployment was associated with lower MCS scores. CONCLUSIONS: Depression is frequently observed among adolescents and young adults with childhood-onset ESKD. Regular screening for psychosocial concerns, maintaining stable graft functions, and achieving optimal nutritional status may contribute to improved well-being among these patients.

The prevalence and associated factors of seasonal exacerbation of subjective symptoms in Japanese patients with restless legs syndrome.

OBJECTIVES: To elucidate the prevalence of seasonal exacerbation in patients with restless legs syndrome (RLS) and identify its associated factors. METHODS: We investigated the presence/absence of seasonal exacerbation of RLS by distributing self-administered questionnaires with an interval of three years. Patients who reported having seasonal exacerbation in both surveys were defined as having seasonal exacerbation. RLS severity was determined using the International Restless Legs Syndrome Rating Scale (IRLS). RESULTS: Among 180 patients, 89 reported having seasonal exacerbation in the first survey. Among them, only two reported not having seasonal exacerbation in the second survey; thus, 87 (48.3%) patients were considered to have a seasonal exacerbation. Although many of them (68 out of 87, 78.2%) experienced exacerbation in spring or summer, 19 out of 87 (21.8%) reported that their symptoms worsened in fall or winter. All the patients in this study had mild to moderate degrees of RLS severity according to the IRLS score. Multiple logistic regression analyses revealed that having a family history of RLS (p < 0.05) and moderate RLS (p < 0.001) were significantly associated with the presence of seasonal exacerbation. CONCLUSIONS: This study revealed that approximately half of all RLS patients had seasonal exacerbation of the symptoms and that about 80% of the exacerbation was observed during the spring/summer season. Moreover, seasonal exacerbation is likely to be present even in patients whose symptoms had been improved to moderate severity with pharmacological treatment.

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.

Characteristics of the treatments for each severity of major depressive disorder: A real-world multi-site study.

PURPOSE: In the treatment guidelines for major depressive disorder (MDD), the recommended treatment differs based on the severity. However, the type of treatment provided based on the severity of MDD in real-world clinical practice has not been investigated. In this study, we clarified the actual situation of MDD treatment in clinical practice and compared the treatment based on the severity of MDD. METHODS: We used data from 1484 patients with MDD at discharge from October 2016 to March 2020. RESULTS: The number of psychotropic prescriptions tended to be lower in those diagnosed with MDD in the severe group compared to in the non-severe group. There were significant differences among the three groups (mild, moderate/severe, and psychotic) in the percentage of patients who were not prescribed antipsychotics (p = 1.9 ×10-6), a combination of antipsychotics and antidepressants (p = 5.0 ×10-4), and the implementation rate of modified electroconvulsive therapy (m-ECT) (p = 3.4 ×10-9). The percentage of patients with a severe diagnosis who underwent m-ECT was higher, which corresponded to the severity. CONCLUSION: Our findings showed that the use of psychotropics decreased when the severity of MDD was diagnosed, and the rate of a combination of antipsychotics and antidepressants and the implementation rate of m-ECT increased with the severity. However, this study suggests that there is still an evidence-practice gap in the treatment of MDD in Japan, and guidelines are only partially adhered to in the treatment of depression.

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.

Psychosocial Assessment of Transplant Candidates: Inter-rater Reliability and Concurrent Validity of the Japanese Version of the Stanford Integrated Psychosocial Assessment for Transplantation.

BACKGROUND: The Stanford Integrated Psychosocial Assessment for Transplantation (SIPAT) is a comprehensive instrument developed to provide a standardized, objective, and evidence-based psychosocial evaluation of the main pretransplant psychosocial risk factors that may influence transplant outcomes. OBJECTIVE: Because established assessment procedures or standardized tools designed to perform pre-solid organ transplant psychosocial evaluation are currently unavailable in Japan, the present study aimed to develop and preliminarily validate the Japanese version of the SIPAT. METHODS: First, the Japanese version of the SIPAT was developed using standard forward-back-translation procedures. Then, the Japanese versions of the SIPAT and the Japanese version of Psychosocial Assessment of Candidates for Transplant were retrospectively and blindly applied to 107 transplant cases by 4 independent raters. RESULTS: The interrater reliability of the scores obtained with the Japanese version of the SIPAT was excellent (Pearson's correlation coefficient = 0.86). The concurrent validity of the SIPAT to the Psychosocial Assessment of Candidates for Transplant for each examiner was substantial (Spearman's rank correlation coefficient = -0.66). CONCLUSION: These findings suggest that the Japanese version of the SIPAT is a promising and reliable instrument. Further research is required to test the predictive validity of the Japanese version of the SIPAT.
