Association between the early repolarization pattern and nocturnal suicide attempts.

AIM: Numerous recent reports have highlighted the association between mental disorders and electrocardiographic findings. The early repolarization pattern (ERP) on electrocardiogram has been linked with a history of suicide attempts and attention deficit hyperactivity disorder, and associations with impulsivity have also been reported. It is known that suicidal intent is more common at night. Patients who have a mental disorder and ERP may have a higher likelihood of impulsivity, potentially increasing the risk of suicide at night. METHODS: The subjects were 43 patients with a history of suicide attempts who had undergone electrocardiographic examination at Jikei University School of Medicine Kashiwa Hospital and received intervention from our department. Due to the diurnal variation in electrocardiographic findings, only patients who underwent the examination during the daytime were included. Patients' clinical backgrounds were compared according to the presence or absence of ERP, and the association between nocturnal suicide attempts and ERP was examined using multivariate analysis. RESULTS: The frequency of nocturnal suicidal behavior was 76.2% in patients with ERP and 31.8% in those without ERP, but the difference was not significant after Bonferroni correction. In the multivariate analysis, there was a significant association of ERP with nocturnal suicide attempts (p = 0.018). CONCLUSION: The finding of an association between ERP and nocturnal suicide attempts indicates that ERP is a biological indicator that can predict nocturnal suicide attempts.

Relationship between the early repolarization pattern and a history of suicide attempts among drug-free psychiatric patients.

AIM: Suicide attempts are an important severe psychiatric symptom and a clear outcome for mental disorders. Although the relationship between the early repolarization pattern in electrocardiogram and psychiatric disorders has recently been reported, these reports have not been able to exclude the influence of psychiatric drugs. This study aimed to investigate the relationship between the early repolarization pattern and a history of suicide attempts among patients not receiving psychiatric medication. METHODS: A total of 71 patients with a history of suicide attempts were investigated, 38 of whom were analyzed for this study. We compared the frequency of the early repolarization pattern between a suicide attempt group and a control group. Then, we investigated the association between the early repolarization pattern and the suicide attempt group by logistic regression analysis, including electrocardiographic findings associated with psychiatric disorders. RESULTS: The findings indicated that the frequency of the early repolarization pattern was significantly higher in the suicide attempt group (n = 20; 52.6%) than in the control group (n = 4; 10.5%) (P < 0.001), and the results of the logistic regression analysis indicated that the early repolarization pattern was associated with suicide attempts. CONCLUSIONS: These findings suggest that the early repolarization pattern is associated with a history of suicide attempts.

Guidelines for diagnosis and treatment of depression in older adults: A report from the Japanese Society of mood disorders.

The Committee for Treatment Guidelines of Mood Disorders, Japanese Society of Mood Disorders, published a Japanese guideline for the treatment of late-life depression in 2020. Based on that guideline, the present guideline was developed and revised to incorporate the suggestions of global experts and the latest published evidence. In the diagnosis of late-life depression, it is important to carefully differentiate it from bipolar disorders, depressive states caused by physical and organic brain disease, drug effects, and dementia, and to determine the comorbidity between late-life depression and dementia. It is necessary to fully understand the clinical characteristics and psychosocial background of late-life depression, evaluate the patient's condition, and provide basic interventions based on these factors. Problem-solving therapy, reminiscence therapy/life review therapy, and behavioral activation therapy, and other forms of psychotherapy can reduce depressive symptoms. In terms of pharmacotherapy, newer antidepressants or non-tricyclic antidepressants are recommended for late-life depression, and it is recommended that the efficacy of least the minimal effective dosage should first be determined. Switching antidepressants and aripiprazole augmentation can be used to treatment-resistant therapy. Electroconvulsive therapy and repetitive transcranial magnetic stimulation have demonstrated usefulness for late-life depression. Exercise therapy, high-intensity light therapy, and diet therapy also show some effectiveness and are useful for late-life depression. Continuation therapy should be maintained for at least 1 year after remission.

Education level is associated with neuropsychiatric symptoms in patients with amnestic-mild cognitive impairment.

BACKGROUND: We examined differences in the severity of neuropsychiatric symptom (NPS) subsyndromes according to education level among patients with amnestic-mild cognitive impairment (a-MCI) with the aim of identifying patient demographics related to NPS subsyndromes. METHODS: Overall, 140 patients with a-MCI were included. We divided the patients into three groups according to their educational level (primary education, middle education, and high education) and compared their demographics. To explore the severity of NPS subsyndromes according to educational level, we used the Neuropsychiatric Inventory (NPI) after adjustments for the Mini-Mental State Examination (MMSE) score. Finally, NPS subsyndromes that were identified as being related to educational level were further explored using a general linear model (GLM). RESULTS: Significant differences in several demographics were observed among the three groups. Among the NPS subsyndromes, the scores for aggressiveness were significantly higher in the primary and high education groups than in the middle education group, while the apathy/eating problem scores were significantly higher in the primary education group than in the other groups. The GLM analyses showed that aggressiveness was related to marital status and the Zarit Caregiver Burden Interview (ZBI-J) score, while apathy/eating problems were related to the instrumental activities of daily living (IADL) percentage, the ZBI-J score, and the education level in years. CONCLUSIONS: Among NPS subsyndromes, aggressiveness and apathy/eating problems differed according to education level in patients with a-MCI. A GLM analysis suggested that not only education level, but also various other factors should be considered when determining the need for NPS interventions.

Clinicodemographic and Psychosocial Factors Related to Presentation or Severity of Delusions of Theft among Females with Amnestic Mild Cognitive Impairment and Alzheimer's Disease.

Objectives: We examined the clinicodemographic and psychosocial factors that relate to the presentation and severity of delusions of theft among female patients with amnestic mild cognitive impairment (a-MCI) and Alzheimer's disease (AD).Methods: We enrolled a total of 177 female patients with a-MCI or AD, of whom 40 presented with delusions of theft. We compared the differences in clinicodemographic and psychosocial factors of the 40 patients (delusions of theft group) with 50 age- and Mini-Mental State Examination (MMSE)-matched controls without delusions (control group). Furthermore, we identified the factors associated with the presentation of delusions of theft using a general linear model (GLM). The severity of delusions of theft was calculated using the Neuropsychiatric Inventory Questionnaire, and correlations between the clinicodemographic and psychosocial factors were examined.Results: Between the two groups, the delusions of theft group had lower scores on the Physical Self-Maintenance Scale and instrumental activities of daily living (IADL) and higher scores on the Japanese version of the Zarit Caregiver Burden Interview (ZBI-J) than the control group. GLM analysis revealed that the IADL score was related to the presentation of delusions of theft. The severity of delusions of theft correlated with the MMSE and the ZBI-J scores in the delusions of theft group.Conclusions: The two groups had several differences regarding clinicodemographic and psychosocial factors. Furthermore, lower IADL scores were related to symptom presentation. Symptom severity correlated with cognitive functioning and caregiver burden.Clinical Implications: In the determination of treatment or care, differences in these factors should be considered.

Effects of neuropsychiatric symptoms of dementia on reductions in activities of daily living in patients with Alzheimer's disease.

AIM: In patients with Alzheimer's disease (AD), cognitive impairments cause a progressive reduction in Activities of Daily Living (ADL). Neuropsychiatric symptoms (NPS) also appear in most patients; however, the association between NPS and reductions in ADL remains unclear. The present study evaluated whether NPS influence such reductions using two different ADL measures in patients with AD. METHODS: Among 546 consecutive outpatients who visited the memory clinic at the Jikei University Kashiwa Hospital, we recruited 208 patients with AD and investigated the correlations between either the Physical Self-Maintenance Scale (PSMS) score or the Instrumental ADL (IADL) level, and each of the Behavioral Pathology in AD (Behave-AD) subscales. To clarify the causal relationships of these correlations, we then verified the associations between statistically significant demographic variables and the Behave-AD subscales as well as the two ADL scales (PSMS score and IADL percentage) using a general linear model. RESULTS: Neither the PSMS nor the IADL results were significantly influenced by the aberrant motor behaviors score. However, the IADL was significantly influenced by the Mini-Mental State Exam (MMSE) score. Furthermore, diurnal rhythm disturbances and the interaction between diurnal rhythm disturbances score and the MMSE score significantly influenced the PSMS results. CONCLUSION: Basic ADL reductions may be influenced by diurnal rhythm disturbances, in addition to cognitive impairments in patients with AD. Furthermore, the interaction between the diurnal rhythm disturbances score and cognitive function may also influence basic ADL. Geriatr Gerontol Int 2020; ••: ••-••.

Sex differences in the severity of neuropsychiatric symptoms and their relationship with clinico-demographic and psychosocial factors in patients with amnestic mild cognitive impairment and mild Alzheimer's disease.

Objectives: We examined differences in the severity of neuropsychiatric symptoms (NPS) according to sex and identified NPS-related clinico-demographic and psychosocial factors among community-living patients with amnestic-mild cognitive impairment (a-MCI) or mild Alzheimer's disease (AD).Method: Overall, 111 patients (44 males, 67 females) with mild a-MCI (n = 64) or mild AD (n = 47) were included. We divided the patients according to sex and compared their clinico-demographic and psychosocial factors, explored the severity of NPS using the subscales from the Neuropsychiatric Inventory-Questionnaire (NPI-Q), and further identified variables related to NPS.Results: Significant differences in several clinico-demographic and psychosocial characteristics were observed between the sexes. The severity of delusions was higher among females (mean, 0.48; SD, 1.60) than males (mean, 0.23; SD, 1.07; p = .02), while the severity of irritability was higher among males (mean, 0.97; SD, 1.92) than females (mean, 0.49; SD, 1.40; p = .03). The severity of delusions among females was related to the duration of cognitive decline (B = 0.37, p = .03), while the severity of irritability among males was related to general cognition (B = -0.40, p = .003).Conclusion: The severity of NPS among patients with a-MCI or mild AD differed according to sex. We identified NPS-related clinico-demographic factors among these patients. Sex differences should be considered when determining the need for NPS interventions.

Executive Dysfunction Correlated With 2-Year Treatment Response in Patients With Late-Life Undifferentiated Somatoform Disorders.

BACKGROUND: Late-life somatoform disorders (SDs) are characterized by various aging-associated factors. Recently, cognitive decline, including executive dysfunction, has been reported as an etiological factor of late-life SDs. The response to treatment for late-life SDs varies from one patient to another. Treatment strategies for late-life SDs require these etiological factors to be considered. We hypothesized that the treatment response in patients with late-life SDs was associated with executive dysfunction. OBJECTIVE: The aim of the present study was to confirm the changes in disease severity over a 2-year follow-up period and to determine which etiological factors are related to the treatment response in patients with late-life SDs. METHODS: We examined 55 patients with late-life SDs who were treated with pharmacotherapy and supportive psychotherapy at baseline. The changes in the disease severity and cognitive profiles over a 2-year follow-up period were evaluated. Additionally, we investigated which etiological factors at baseline were related to treatment resistance. RESULTS: Of the 55 patients who were enrolled in the present study, 31 completed the 2-year follow-up period. Overall, the disease severity improved significantly in patients with late-life SDs. On the contrary, executive function decreased throughout the research period. Moreover, we found that executive dysfunction and the presence of hyperlipidemia at baseline were related to treatment resistance. CONCLUSIONS: These results suggest that aging-associated etiological factors be considered for the treatment of late-life SDs.

White matter hyperintensities are associated with the severity of late-life somatoform disorders and executive functions.

BACKGROUND: Medically unexplained symptoms are often seen in the elderly. Recently, correlations between medically unexplained symptoms and somatoform disorders (SDs) have been reported. The existence of many interactive psychiatric aetiologies is known among SDs. Late-life SDs might be influenced by some aetiological factors caused by ageing processes, such as structural changes in the brain and cognitive dysfunctions. AIMS: Under such circumstances, we investigated the presence of subcortical white matter hyperintensities (WMHs), which increase with ageing, and hypothesized that subcortical WMHs are related to the disease severity of late-life SDs. Furthermore, we confirmed whether cognitive dysfunction influences this process. METHODS: To evaluate these hypotheses, we examined patients with medically unexplained symptoms who met the criteria for undifferentiated somatoform disorder and divided the patients into three groups according to the degree of subcortical WMHs: grade 0, grade 1, and grade 2. The subcortical WMHs were rated using Fazekas grading. Differences in symptom severity and cognitive functions were compared among the three groups. RESULTS: The grade 2 group had the severest symptoms. Furthermore, the grade 2 group had lower cognitive function scores than the other groups. CONCLUSIONS: The present study showed that the presence of subcortical WMHs in patients with late-life SDs was a predictor of disease severity. Moreover, cognitive dysfunction appeared to play a role in the advancement of disease severity.

Cognitive Dysfunction in Patients With Late-Life Somatic Symptom Disorder: A Comparison According to Disease Severity.

BACKGROUND: Late-life somatic symptom disorder (SSD) is characterized by various aging-associated factors, such as a functional decline, psychosocial problems, and cognitive dysfunction. However, the details of the cognitive dysfunction that occur in late-life SSD are still unknown. OBJECTIVE: The aims of this study were to reveal the cognitive profile of patients with late-life SSD and to evaluate how cognitive dysfunction affects disease severity. METHODS: We compared the cognitive profiles of patients with late-life SSD (n = 40) with those of normal control subjects (n = 21). In addition, we divided the patients with late-life SSD into mild-to-moderate (n = 24) and severe (n = 16) groups and compared the cognitive profiles of the 3 groups. RESULTS: Patients with late-life SSD exhibited a lower Mini-Mental State Examination total score and attention decline. In the 3-group comparison, the severe group had a lower Mini-Mental State Examination score and Frontal Assessment Battery score than the normal control group, whereas no significant difference was seen between the mild-to-moderate and the normal control groups. CONCLUSIONS: Our data suggest that different cognitive patterns may exist depending on disease severity, possibly indicating differences in pathogenesis.

Association between BDNF polymorphism (Val66Met) and executive function in patients with amnestic mild cognitive impairment or mild Alzheimer disease.

BACKGROUND: In the present study, we examined whether brain-derived neurotrophic factor (BDNF) polymorphism (Val66Met) influenced the changeable executive dysfunction of patients with two separate disease stages: amnestic mild cognitive impairment (A-MCI) or mild Alzheimer disease (AD), which are comparatively similar demented conditions. METHODS: Among 200 outpatients with dementia and MCI, 146 outpatients with mild AD or A-MCI were recruited and divided into two genotypic groups, valine homozygosity (Val/Val) and methionine (Met) carriers, based on the representative BDNF functional polymorphism Val66Met. Next, we compared the Frontal Assessment Battery (FAB) total and subtest scores between the two genotypic groups according to each of two different disease stages: A-MCI (n = 42) and mild AD (n = 104). RESULTS: Among patients with only a mild stage of AD, the FAB total and go/no-go scores were significantly lower (p < 0.05) among the subjects with the Val/Val genotype than among the Met carriers. However, no significant differences in any other demographic variables were observed between the genotypes according to each of different disease stages. A significant interaction between Val66Met and age was not observed for the FAB scores. CONCLUSION: These results suggested that the BDNF gene may significantly influence executive dysfunction, including inhibition tasks, among patients with mild-stage AD.

The relationship between the severity of depressive symptoms and diabetes-related emotional distress in patients with type 2 diabetes.

OBJECTIVE: To examine the relationship between the severity of depressive symptoms and the burden through diabetes care, or diagnosed diabetes in patients with type 2 diabetes, irrespective of the diabetic complications and glycemic control. PATIENTS AND METHODS: Subjects were 126 outpatients with type 2 diabetes who completed the Beck Depression Inventory-II (BDI-II), Problem Areas in Diabetes (PAID) scale, and Short Form-36 (SF-36). RESULTS: The factor with a significant impact on the BDI-II score in the multiple regression model was the PAID score (standardized coefficient =0.17, 95% confidence interval [CI], 0.12-0.21). The factors having a significant impact on the physical component summary of SF-36 (PCS) in the multiple regression model were BDI-II score (-0.95; 95% CI, -1.32 - -0.58), age (-0.43; 95% CI, -0.61 - -0.25), and the number of complicated macroangiopathies (-8.90; 95% CI, -12.71 - -5.08). The factors with a significant impact on the mental component summary of SF-36 (MCS) in the multiple regression model were BDI-II score (-0.90; 95% CI, -1.16 - -0.65) and age (0.13; 95% CI, 0.00-0.25). CONCLUSION: These findings show that diabetes-related emotional distress is significantly related to the severity of depressive symptoms in patients with type 2 diabetes, independent of the severity of complications and glycemic control. Moreover, the severity of depressive symptoms is negatively correlated with comprehensive health-related QOL in patients with type 2 diabetes. Clinicians need to consider factors other than indices of metabolic control and diabetic complications, in determining the adverse effects of depressive symptoms on the physical QOL of patients with type 2 diabetes.

Differentiation between amnestic-mild cognitive impairment and early-stage Alzheimer's disease using the Frontal Assessment Battery test.

BACKGROUND: Previous research has described the executive dysfunction that occurs in patients with amnestic-mild cognitive impairments (A-MCI) and early-stage Alzheimer's disease (EAD), which are comparatively similar stages of dementia. The aim of the present cross-sectional study is to evaluate executive dysfunction using the Frontal Assessment Battery (FAB) screening test in two groups and to investigate the interaction with other cognitive impairments. METHODS: Among 170 consecutive patients with Alzheimer's disease or A-MCI, we recruited 48 subjects who were under 75 years of age and had been diagnosed as having either A-MCI or EAD. We then compared the total and the subtest scores of the mini-mental state examination (MMSE) and the FAB between the two groups. Moreover, we investigated the statistical interactive associations of the FAB subtest scores with the influential MMSE subtest scores or the diagnosis (A-MCI or EAD). RESULTS: No significant differences in the age, sex ratio, duration of illness, and education years were observed between the two groups. However, significant differences in the FAB total and subtest scores (conflicting instructions and go/no-go) were found between the two groups. Furthermore, significant differences in the MMSE total and subtest scores (orientation, memory delayed recall, and attention and calculation) were also noted between the two groups. In a generalized linear model analysis, only two FAB subtest scores (conflicting instructions and go/no-go) were significantly influenced by the diagnosis (A-MCI or EAD) in a manner that was independent of the interaction with the orientation or memory delayed recall. CONCLUSION: The present findings suggest that the FAB total score and subtest scores reflecting interference performances (conflicting instructions and go/no-go) significantly declined in patients with EAD, independent of the disorientation and memory disorder. Such characteristics of neuropsychological screening test scores may be useful to clinicians for differentiating EAD and A-MCI at bedside.

Association between brain-derived neurotrophic factor (BDNF) gene polymorphisms and executive function in Japanese patients with Alzheimer's disease.

BACKGROUND: To address the functional roles of genetic polymorphisms of brain-derived neurotrophic factor (BDNF) in Alzheimer's disease (AD) from a neuropsychological aspect, we used a cross-sectional study design to investigate the association between novel single nucleotide polymorphisms (SNPs) of the BDNF gene (Val66Met (G196A) and C270T) and the Frontal Assessment Battery (FAB) score, which reflects executive function as a non-memory cognitive impairment. METHODS: One hundred and sixty-nine outpatients with AD or amnestic mild cognitive impairment (A-MCI) were recruited to the study and divided into three genotypic groups for each representative BDNF functional polymorphism as follows: (i) Val66Met (G196A): G/G (n = 45), G/A (n = 104), and A/A (n = 20); and (ii) C270T: C/C (n = 160), C/T (n = 9), and T/T (n = 0). Then, age, sex ratio, duration of illness (months), education years, Mini-Mental State Examination (MMSE) score, behavioral pathology in Alzheimer disease (Behave-AD) score, Clinical Dementia Rating (CDR) ratio, and total and subtest FAB scores were compared between the genotypic groups for each SNP. RESULTS: Significant differences were found in the total (P < 0.01) and subtest (conflicting instructions and prehension behavior; P < 0.01) FAB scores between the C270T polymorphism groups (C/C and C/T), but not among the G196A polymorphism groups. However, no significant differences in age, sex ratio, duration of illness (months), education years, Behave-AD score, CDR ratio, or MMSE score (reflecting attention and memory function) were found between the individual polymorphism genotypes (G196A and C270T). CONCLUSION: Of the known BDNF polymorphisms, the C270T SNP may influence executive dysfunction as a non-memory cognitive impairment in Japanese patients with AD.

Association between nerve growth factor gene polymorphism and executive dysfunction in Japanese patients with early-stage Alzheimer's disease and amnestic mild cognitive impairment.

BACKGROUND/AIMS: To address the clinical neurocognitive roles of nerve growth factor (NGF) genetic polymorphism in early-stage Alzheimer's disease (AD) and amnestic mild cognitive impairment (A-MCI), we investigated the association between this single-nucleotide polymorphism (SNP) and executive dysfunction as a nonmemory cognitive impairment. METHODS: Among 200 outpatients with dementia and MCI whose NGF SNP rs6330 genotype was identified, those with A-MCI (n = 35) and early-stage AD (n = 67) were recruited and divided into three groups according to genotype (C/C: n = 58, C/T: n = 39, T/T: n = 5). Then, the Frontal Assessment Battery (FAB) scores were compared among the three (C/C, C/T, T/T) or two (C/C, T carrier) genotype groups. RESULTS: Among the subtests, a significant difference was only noted for the go/no-go scores (p < 0.01) between C/C and T carriers. However, no significant differences in the demographic variables and other neuropsychological subtest scores reflecting attentional and memory function were observed among the genotypes. CONCLUSION: Regarding the functional roles of neurotrophin polymorphisms as they relate to executive dysfunction, the NGF gene rs6330 might influence the inhibition task in Japanese patients with early-stage AD or A-MCI.

Association between executive dysfunction and hippocampal volume in Alzheimer's disease.

BACKGROUND: Some previous research has hypothesized that executive dysfunction in patients with early Alzheimer's disease (AD) occurs as a result of a disconnection between different cerebral areas. The aim of the present study was to evaluate how the hippocampal volume influences executive function as a non-memory cognitive function. METHODS: From 157 consecutive patients with AD or amnestic mild cognitive impairment (A-MCI), we recruited 107 subjects who had a global Clinical Dementia Rating (CDR) of 0.5 or 1.0 and whose degree of hippocampal atrophy had been measured using magnetic resonance imaging (MRI); the severity of atrophy was assessed using the voxel-based specific regional analysis for Alzheimer's disease (VSRAD) system. We divided the subjects into three groups: mild atrophy, 0 < Z-score < 1.0 (N = 21); moderate atrophy, 1.0 ≤ Z-score < 2.0 (N = 46); or severe atrophy, 2.0 ≤ Z-score < 4.0 (N = 40) according to the Z-score and compared the Frontal Assessment Battery (FAB) and its subtest scores between each atrophy group. RESULTS: The results demonstrated that age, sex ratio, duration of illness, education years, MMSE score, Behave-AD score, and proportion of atrophy area in total brain (%) were not significantly different among the three groups. Only the go/no-go score among the six subtests was significantly lower for increasing atrophy severity (P < 0.05). Furthermore, hippocampal atrophy significantly influenced the go/no-go score independently of interactions from whether the diagnosis was early AD or A-MCI (P < 0.05). CONCLUSION: These results support a significant association between hippocampal atrophy and executive dysfunction as a non-memory cognitive impairment in patients with early AD and A-MCI.

Relationship of frontal lobe dysfunction and aberrant motor behaviors in patients with Alzheimer's disease.

BACKGROUND: In order to address the neuropsychological pathogenesis of aberrant motor behaviors in Alzheimer's disease (AD), we used a cross-sectional study design to investigate the association between frontal lobe function, including executive function, and activity disturbances (wandering, purposeless activities and inappropriate activities). METHODS: Among 75 consecutive outpatients with AD, 50 subjects with a Clinical Dementia Rating (CDR) score of 1 or 2 were selected and divided into two groups based on data obtained from interviews with their caregivers: an aberrant motor behaviors (AMB) group (n = 22), and a non-aberrant motor behaviors (NAMB) group (n = 28). Aberrant motor behavior was defined according to whether the "activity disturbance" score (ranging from 0 to 9) of the Behavioral Pathology in Alzheimer Disease (Behave-AD) scale was 0 or >or=1. The total and subtest scores of the Frontal Assessment Battery (FAB) were then compared between the two groups. RESULTS: Significant differences were found between the FAB total (P < 0.05) and the subtest scores (lexical fluency, conflicting instructions; P < 0.05) in the two groups. The FAB score was significantly associated with the activity disturbance score (r = -0.49; P<0.001). A stepwise multiple regression analysis showed that only the FAB score significantly influenced the activity disturbance score (P < 0.001). CONCLUSIONS: This finding suggested that in addition to episodic memory disturbance, frontal lobe dysfunctions might lead patients with AD to develop aberrant motor behavior.

Clonazepam for chemotherapy-induced nausea and vomiting (CINV).

BACKGROUND: A 51-year-old woman experienced refractory chemotherapy-induced nausea and vomiting (CINV) in spite of extensive antiemetic therapy, including 5-HT3 antagonists, corticosteroids, dopamine antagonists and antihistamines. CASE REPORT: We administered the patient clonazepam. After taking clonazepam, the patient fully recovered from the nausea and vomiting and never experienced them again. CONCLUSION: Clonazepam may be useful in the control of CINV. We believe that clonazepam contributed to the favorable outcome by expressing an anxiolytic and an anticonvulsant effect on myoclonus. The efficacy of clonazepam in this indication of prevention of CINV warrants further investigation.

Psychological distress of family members with cancer patients in Japan.

BACKGROUND: There were no previous studies in Japan on the psychological distress of members of families with cancer patients which focussed on the disclosure of the diagnosis of cancer. This study was designed to investigate factors that may have an effect on the psychological distress of family members. METHODS: The subjects were 95 members of families of cancer patients in the surgical ward; one member was recruited from each patient's family. The psychiatrist investigated the demographic factors of both the patient and the family member: for the patient - gender, age, occupation, cancer site, disclosure (or not) of cancer diagnosis, cancer stage and performance status (PS); for the family member - gender, age, occupation, relationship to the patient, physical illness, frequency of visiting the ward, the period from when the family member was informed of the diagnosis, and any past experience of the loss of close relatives due to cancer. Furthermore, we conducted a survey on the family member's anxiety and depression by using the Spielberger State - Trait Anxiety Inventory (STAI) and the Center for Epidemiological Studies Depression Scale (CES-D). RESULTS: A multiple regression analysis indicated that the factors which were associated with the STAI scores independently were the lack of disclosure of the diagnosis to the patient (P=0.01), and advanced or recurrent cancer (P=0.01). The factors which were associated with the CES-D scores independently were the lack of disclosure of the diagnosis to the patient (P=0.03), advanced or recurrent cancer (P=0.01), and the family member's past history of psychiatric disorders (P=0.01). CONCLUSIONS: The results suggested that the psychological distress of a family member increases when the patient is not informed of the cancer diagnosis, when the cancer is advanced or recurrent, and when the family member has a past history of psychiatric disorders. (Int J Psych Clin Pract 2002; 6: 205-210 ).
