Feasibility and Preliminary Effectiveness of Behavioral Activation for Patients with Cancer and Depression in Japan.

Background: Though the effectiveness of behavioral activation (BA) for patients with cancer and depression were reported, there is no evidence in Japan. Objectives: This study aimed at examining the feasibility and preliminary effectiveness of BA for patients with cancer and depression in Japan. Methods: This pre-post study without a control group was conducted in patients with cancer and depression in Japan. The program completion rate was compared with those of previous studies to examine feasibility. To examine the preliminary effectiveness, outcomes were evaluated four times: before and immediately after the program, and two weeks and three months after the program ended. The primary outcome was the remission rate of depression using the 17-item version of the GRID Hamilton Rating Scale for Depression (HAMD17). Secondary outcomes were self-reported depression, anxiety, quality of life, changes in behavior, values, and perceived reward of activity and environmental factors. Pre- and post-program data were compared using paired-samples t-tests, and data obtained at four time points were analyzed using one-way repeated-measures analysis of variance. Results: Of the 68 patients recruited from February 2018 to January 2022, 32 were registered. The completion rate was 75% (24/32), which was similar to previous studies. The total HAMD17 score significantly improved after the program. The remission rate of depression was 62.5% (20/32), which was above the defined threshold value (30%). All but two secondary outcomes significantly improved after the program (p < 0.05). Conclusions: The feasibility and preliminary effectiveness of BA for patients with cancer and depression in Japan were suggested.The Clinical Trial Registration number: UMIN 000036104.

Behavioral activation for depression in patients with advanced cancer: study protocol for a multicenter randomized controlled trial.

BACKGROUND: Though behavioral activation (BA) has been shown to be effective for depression, evidence in patients with advanced cancer has not been established. This study aimed to examine the effectiveness of a BA program on depression in this population. METHODS: A randomized controlled trial with a wait-list control group (waiting group) of 38 patients with advanced cancer and depression will be conducted at three sites in Japan. The BA program consists of seven sessions. Outcome measures will be evaluated at three times in the intervention group; at the entry, at the end of the intervention and 4 months after the end of the intervention and four times in the waiting group: at the entry, before the intervention, at the end of the intervention, and 4 months after the end of the intervention. Primary outcome is Beck Depression Inventory-II (BDI-II) score. To examine the main effect of the intervention, two-way repeated measures analysis of variance (ANOVA) will be conducted, with timing and intervention status as the independent variables and BDI-II score as the dependent variable. One-way repeated measures ANOVA will be conducted to combine data from the intervention and control groups and examine changes in BDI-II scores by timing in both groups. Secondary endpoints (anxiety, quality of life, spirituality, degree of behavioral activation, value, and pain) will be evaluated with rating scales. Two-way repeated measures ANOVA will be conducted to examine whether there are differences between the groups before and after the intervention, with timing and intervention status as the independent variables and scores on each rating scale as the dependent variables. DISCUSSION: This multicenter randomized controlled trial is the first study to assess the effectiveness of BA on depression in patients with advanced cancer. Our findings will provide evidence about the effectiveness of BA on depression and provide an intervention option that is acceptable and feasible for the treatment of depression in this population. The results of this study will lead to improved mood and rebuilding to regain life purpose and value in this vulnerable population.

The mediating effect of activity restriction on the relationship between perceived physical symptoms and depression in cancer survivors.

PURPOSE: Several studies have explored factors causing depression in cancer survivors, including perceived physical symptoms. Another critical factor in the depression symptomatology of cancer survivors is activity restriction (AR). We investigated how AR mediate the effects of perceived pain and fatigue on depression in cancer survivors. METHODS: Cancer survivors (n = 61; mean age 56.16 years) that were recruited through cancer support groups in Japan participated in this study. Participants completed a battery of questionnaires comprising demographic and clinical information, the Pain Catastrophizing Scale, the Cancer Fatigue Scale, the Activity Restriction Scale for Cancer Patients, and the Hospital Anxiety and Depression Scale. RESULTS: Mediation analysis indicated that AR partially mediates the effect of pain on depression. Direct paths from pain to AR, AR to depression, and pain to depression were significant (P < .005). Moreover, indirect paths from pain to AR, AR to depression, and pain to depression were also significant at the 95% level [0.04-0.13]. However, AR did not mediate the effect of fatigue on depression, and fatigue had a significant direct path to both AR and depression (P < .005). CONCLUSION: This study aimed to explore the mediating effect of AR in the relationships of perceived pain and fatigue and depression in cancer survivors. We found that AR mediates perceived pain to depression, however not for perceived fatigue. In addition, because AR was experienced in the face of any survivorship period, AR may need to be treated as a long-term effect of the cancer diagnosis.

Investigation of thyroid cancer cases that were not detected in the Thyroid Ultrasound Examination program of the Fukushima Health Management Survey but diagnosed at Fukushima Medical University Hospital.

The Great East Japan Earthquake, which occurred on March 11, 2011, and its subsequent Fukushima Daiichi Nuclear Power Plant accident, prompted implementation of the Thyroid Ultrasound Examination (TUE) program as a part of the Fukushima Health Management Survey. The purpose of this program is to support residents of Fukushima Prefecture, and to analyze the health effects of the released radionuclides. Regardless of relatively high participation rates and a well-planned diagnostic flow, it is conceivable that not all thyroid cancer cases can be detected by the TUE program. The aims of the present study were to identify and characterize these "outside" cases, targeting patients at Fukushima Medical University (FMU) Hospital. As of June 30, 2017, we have successfully identified 11 outside cases. These corresponded to 5.7% of the 194 subjects who were identified as having thyroid cancer or suspected thyroid cancer in the TUE program. Although the outside subjects of other institutes were not investigated, the present study may have identified the majority of outside subjects in Japan, considering that FMU Hospital treats a large number of thyroid cancer subjects. Furthermore, the characteristics of the 11 subjects were not different from those of the subjects identified in the TUE program. These findings confirm that the TUE program was able to identify subjects of thyroid cancer adequately and sufficiently.

Interaction Effects of Behavioral Inhibition System/Behavioral Activation System and Cost/Probability Biases on Social Anxiety.

INTRODUCTION: Social anxiety disorder (SAD) symptoms are maintained by cognitive biases, which are overestimations of the severity and likelihood of negative social events (cost/probability biases), and by sensitivity to rewards and punishments that are determined according to behavioral inhibition/behavioral activation systems (BIS/BAS). Cost/probability biases might activate the behavioral immune system and exacerbate the avoidance of social events. Earlier studies have proposed that low BIS or high BAS decrease SAD symptoms; BIS/BAS may even change the effects of cognitive biases on SAD symptoms. Hence, the current study investigates the interaction effects of BIS/BAS and cost/probability biases on SAD symptoms. METHOD: Seventy-six Japanese undergraduate students completed the Japanese version of the Liebowitz Social Anxiety Scale (LSAS), which comprises Fear and Avoidance subscales, the BIS/BAS Scale, and the Social Cost Probability Scale. RESULTS: A multiple regression analysis was performed to examine whether cost/probability biases, BIS/BAS, and their interactions affected SAD symptoms; following this, the main effects of cost bias and BIS were determined for LSAS-Fear (ß = 0.64, p < 0.001; ß = 0.33, p < 0.01) and LSAS-Avoidance (ß = 0.49, p < 0.001; ß = 0.35, p < 0.01). The interaction effect between cost bias and BAS was significant for LSAS-Avoidance (ß = -0.32, p < 0.05). Simple slope analysis showed that the slope of cost bias was significant for low-BAS individuals (ß = 0.77, p < 0.001) but not for high-BAS individuals (ß = -0.21, n.s.). The interaction effect between probability bias and BAS was significant for LSAS-Avoidance (ß = 0.40, p < 0.01) as well. Further, simple slope analysis revealed that the slope of probability bias was significant for low-BAS individuals (ß = -0.53, p < 0.05) but not for high-BAS individuals (ß = 0.17, n.s.). DISCUSSION: The study found interesting results with respect to the avoidance of social events. Low-BAS individuals with high cost or low probability biases regarding social events may have a tendency to avoid social events. In contrast, if high-BAS individuals overestimate the cost of social events or underestimate the probability of social events, their anticipation of rewards might prevent them from avoiding social events.

Behavioral activation therapy for depression and anxiety in cancer patients: a case series study.

BACKGROUND: Behavioral activation therapy (BAT) directly addresses activities that individuals value most highly, and may be easily applicable to cancer patients. However, there is no established evidence of the use of BAT in this population. In this study, we examined the possibility of a BAT program for depression and anxiety in cancer patients. CASE PRESENTATION: We retrospectively reviewed the medical records of cancer patients with each of the following characteristics: 1) were outpatients or inpatients visiting the psycho-oncology division of the National Cancer Center Hospital in Japan; 2) met criteria for Major Depressive Disorder or Adjustment Disorders; and 3) participated in a BAT program. The primary outcome was the program completion percentage. Secondary outcomes were self-reported depression severity (Patient Health Questionnaire-9 (PHQ-9) score), anxiety disorder status (Generalized Anxiety Disorder-7 (GAD-7) score), and clinical improvement (Clinical Global Impression-Improvement (CGI-I) score) after the program. We analyzed both depression and anxiety by the matched paired t-test. Ten patients participated in the program, and nine completed it. One dropped out due to cognitive impairment secondary to brain metastasis. Both the PHQ-9 scores (pre: 14.4 (SD, 6.1); post: 5.1 (SD, 5.8)) and the GAD-7 scores (pre: 11.9 (SD, 4.9); post: 4.7 (SD, 5.5)) significantly improved after the program (PHQ-9: P = 0.0014; GAD-7: P = 0.0004). CGI-I scores ranged from 1 to 3, and all subjects except the patient who dropped out improved clinically. Among the ten patients, three distinctive cases could be observed as follows. Case 1; a 45-year-old housewife with breast cancer who did not agree to take antidepressants because of concerns about the side effects achieved remission without antidepressants and began to live an active life. Case 4; a 66-year-old housewife was so shocked after endometrial cancer diagnosis that she was absent-minded and her compliance with the assigned homework was poor, therefore, her depression did not improve much. Case 9; a 62-year-old man with laryngeal cancer who had recurrent anxiety. Increased business activity, on which he put great value, gradually allowed him to be able to live his life actively without concerns. CONCLUSIONS: This study suggests that BAT would be effective for the depression and anxiety of cancer patients.

Incidence of Thyroid Cancer Among Children and Young Adults in Fukushima, Japan, Screened With 2 Rounds of Ultrasonography Within 5 Years of the 2011 Fukushima Daiichi Nuclear Power Station Accident.

Importance: Ultrasonographic (US) screening for thyroid cancer was performed in the Fukushima Health Management Survey after the 2011 Fukushima Daiichi nuclear power station accident. Clinical characteristics of thyroid cancers screened by US among children and young adults during the first 5 years after the accident were analyzed. Objectives: To evaluate the number of detected thyroid cancers by age group within 5 years of the Fukushima Daiichi nuclear power station accident and to compare the basic clinical characteristics and demographic patterns in first- and second-round examinations. Design, Setting, and Participants: In this observational study, 324 301 individuals 18 years or younger at the time of accident were included. Patients received a cytologic diagnosis of malignant or suspected malignant thyroid cancer during the first (fiscal years 2011-2013) or second round (fiscal years 2014-2015) of screening. Number of detected cases of cancer was evaluated, correcting for the number of examinees by age group at the time of the accident and for the incidence of detected cancers according to age group at the time of the screening (age groups were divided into 3-year intervals). Results were compared using the age-specific incidence of unscreened cancers from a national cancer registry. Main Outcomes and Measures: Clinical baseline characteristics of the patients and the age-specific number and incidence of thyroid cancers detected during the second round. Results: Among 299 905 individuals screened in the first round (50.5% male; mean [SD] age at screening, 14.9 [2.6] years), malignant or suspected thyroid cancer was diagnosed in 116. Among 271 083 individuals screened in the second round (50.4% male; age at screening, 12.6 [3.2] years), malignant or suspected thyroid cancer was diagnosed in 71. The most common pathologic diagnosis in surgical cases was papillary thyroid cancer (149 of 152 [98.0%]). The distribution pattern by age group at the time of the accident, where the number of detected thyroid cancer cases was corrected by the number of examinees, increased with older age in both screening rounds. This demographic pattern was similar between the first and second examinations. The distribution pattern of the incidence rate by age group at the time of screening in the second round also increased with older age. The incidence rate detected by screening was 29 cases per 100 000 person-years for those aged 15 to 17 years, 48 cases per 100 000 person-years for those aged 18 to 20 years, and 64 cases per 100 000 person-years for those aged 21 to 22 years. Conclusions and Relevance: Large-scale mass US screening of young people resulted in the diagnosis of a number of thyroid cancers, with no major changes in overall characteristics within 5 years of the 2011 Fukushima nuclear power station accident. These results suggest that US screening can identify many detectable cancers from a large pool of nonclinical and subclinical thyroid cancers among individuals of a relatively young age, in an age-dependent manner.

Comparative Analysis of the Growth Pattern of Thyroid Cancer in Young Patients Screened by Ultrasonography in Japan After a Nuclear Accident: The Fukushima Health Management Survey.

IMPORTANCE: Thyroid cancer generally grows at a very slow rate in adults, and overdiagnosis is a global issue. However, the detection of early-stage thyroid cancer by screening is not well described in young patients. To prevent overdiagnosis, it is essential to understand the natural course of thyroid cancer growth detection by ultrasonography screening in young patients. OBJECTIVE: To evaluate the natural progression of thyroid cancer in young patients. DESIGN, SETTING, AND PARTICIPANTS: An observational study evaluated changes in the diameter of malignant or suspected malignant thyroid tumors on 2 occasions. Changes in malignant thyroid tumor diameter were estimated during the observation period between the screening and confirmatory examinations in the first-round thyroid ultrasonography examination of the Fukushima Health Management Survey in patients younger than 21 years after a nuclear accident at a power plant in Fukushima, Japan. In total, 116 patients cytologically diagnosed with or suspected to have thyroid cancer were classified into 3 groups based on a greater than 10% reduction, a change of -10% to +10% in diameter, and a greater than 10% increase in tumor diameter. The association between tumor growth rate and tumor diameter was analyzed. The study was conducted from March 1, 2016, to August 6, 2017. MAIN OUTCOMES AND MEASURES: Tumor volume changes, the coefficient of growth of thyroid cancer in young patients, and the association between the observation period or tumor diameter and them. RESULTS: Of 116 patients, 77 were female; the mean age was 16.9 years (median, 17.5 years). The mean observation period was 0.488 (range, 0.077-1.632) years. No significant differences in age, sex, tumor diameter, observation period, or serum levels of thyrotropin and thyroglobulin were observed among the groups. Whereas tumor volume changes were not linearly correlated with the observation period (Pearson R = 0.121; 95% CI, -0.062 to 0.297), the coefficient of growth was significantly and negatively correlated with the tumor diameter in the screening examination (Spearman ρ = -0.183; 95% CI, -0.354 to -0.001), suggesting growth arrest after the initial proliferation phase. CONCLUSIONS AND RELEVANCE: Ultrasonography screening could reveal asymptomatic thyroid cancer that is falling into a growth arrest pattern in many young patients. Considering the long life expectancy, prevention of overdiagnosis necessitates careful long-term monitoring without immediate diagnosis for suspected noninvasive thyroid cancer.

ING2, a tumor associated gene, enhances PAI­1 and HSPA1A expression with HDAC1 and mSin3A through the PHD domain and C­terminal.

Inhibitor of growth 2 (ING2) is involved in chromatin remodeling and it has previously been suggested that ING2 may regulate gene expression. The authors previously identified matrix metalloproteinase 13 (MMP13) as a target gene of ING2 in colorectal cancer. The aim of the present study was to identify novel genes regulated by ING2 and histone deacetylase 1 (HDAC1) and to clarify the biological significance of the ING2 structure. The present study generated the point mutant constructs of ING2 and deletion constructs consisting of partial ING2 to investigate the effect on gene expression and verify the interaction with HDAC1, mSin3A and sap30. A microarray was performed to find novel ING2/HDAC1 target genes using cell co­overexpression of ING2 and HDAC1. Plasminogen activator inhibitor­1 (PAI­1) was upregulated with overexpression of ING1b and ING2. The mutation of the PHD domain at 218 significantly attenuated the MMP13 and PAI­1 expression, whereas the mutation at 224 resulted in increased expression. Furthermore, the expression levels were slightly reduced by the mutation of the C­terminal. The lack of the PHD domain and the C­terminal in ING2 resulted in a decreased ability to induce gene expression. The C­terminal with PHD domain, which lacked the N­terminal, maintained the transactive function for regulating the target genes. In addition to MMP13 and PAI­1, eight genes [heat shock protein family A member 1A (HSPA1A), MIR7­3 host gene, chorionic somatomammotropin hormone 1, growth arrest and DNA damage inducible b, dehydrogenase/reductase 2, galectin 1, myosin light chain 1, and VGF nerve growth factor inducible] were demonstrated to be associated with ING2/HDAC1. The present study demonstrated that ING2/HDAC1 regulated PAI­1 and HSPA1A expression and the PHD domain and the C­terminal of ING2, which are binding sites of HDAC1 and mSin3A, are essential regions for the regulation of gene expression.

Avoidance behavior associated with depressive symptoms in patients with implantable cardioverter defibrillators / Conducta de evitación asociada a síntomas depresivos en pacientes con desfibriladores cardioversores implantables

Objective: Many patients with implantable cardioverter defibrillators experience depressive symptoms. In addition, avoidance behavior is a common problem among patients with implantable cardioverter defibrillators. We examined the association between avoidancebehaviors and depressive symptoms in patients with implantable cardioverter defibrillators. Method: We conducted a single-center, cross-sectional study with self-completed questionnaires between May 2010 and March 2011. We measured avoidance behaviors (avoidance of places, avoidance of objects, and avoidance of situations) and depressive symptoms (using the Beck Depression Inventory, Version II) in 119 participants. An avoidance behaviors instrument was developed for this study and we confirmed its internal consistency reliability. Results: Ninety-two (77.3%) patients were aged older than 50 years, and 86 (72.3%) were men. Fifty-one (42.9%) patients reported «avoidance of places», 34 (28.6%) reported «avoidance of objects», and 63 (52.9%) reported «avoidance of activity». Avoidance behavior was associated with increased odds for the presence of depressive symptoms (OR 1.31; 95% CI 1.06-1.62). Conclusions: This was the first study to identify the relationship between avoidance behavior and depressive symptoms among patients with implantable cardioverter defibrillators; however, there are a few methodological limitations (AU)

El objetivo fue examinar la asociación entre las conductas de evitación y síntomas depresivos en pacientes con desfibriladores cardioversores implantables. Método: Se llevó a cabo un estudio transversal en un único centro entre mayo de 2010 y marzo de 2011. Mediante autoinformes se midieron conductas de evitación (evitación a lugares, evitación a objetos y evitación a situaciones) y síntomas depresivos (mediante el Inventario de Depresión de Beck, Versión II) en 119 participantes. El instrumento de evitación se desarrolló para este estudio con adecuada fiabilidad de consistencia interna. Resultados: Noventa y dos pacientes (77,3%) tenían más de 50 años y 86 pacientes (72,3%) eran hombres. Cincuenta y un pacientes (42,9%) informaron de «evitación a lugares», 34 pacientes (28,6%) informaron de «evitación a objetos» y 63 pacientes (52,9%) informaron «evitación a actividad». La conducta de evitación se asoció con un aumento en la probabilidad de síntomas depresivos (OR 1,31; IC del 95%, 1,06-1,62). Conclusiones: Este es el primer estudio para identificar la relación entre la conducta de evitación y síntomas depresivos en pacientes portadores de desfibriladores cardioversores implantables, aunque existen algunas limitaciones metodológicas (AU)

Cognitive behavioral therapy changes functional connectivity between medial prefrontal and anterior cingulate cortices.

BACKGROUND: Depression is characterized by negative self-cognition. Our previous study (Yoshimura et al. 2014) revealed changes in brain activity after cognitive behavioral therapy (CBT) for depression, but changes in functional connectivity were not assessed. METHOD: This study included 29 depressive patients and 15 healthy control participants. Functional Magnetic Resonance Imaging was used to investigate possible CBT-related functional connectivity changes associated with negative emotional self-referential processing. Depressed and healthy participants (overlapping with our previous study, Yoshimura et al. 2014) were included. We defined a seed region (medial prefrontal cortex) and coupled region (ACC) based on our previous study, and we examined changes in MPFC-ACC functional connectivity from pretreatment to posttreatment. RESULTS: CBT was associated with reduced functional connectivity between the MPFC and ACC. Symptom change with CBT was positively correlated with change in MPFC-ACC functional connectivity. LIMITATIONS: Patients received pharmacotherapy including antidepressant. The present sample size was quite small and more study is needed. Statistical threshold in fMRI analysis was relatively liberal. CONCLUSIONS: CBT for depression may disrupt MPFC-ACC connectivity, with associated improvements in depressive symptoms and dysfunctional cognition.

Dysfunction of ventrolateral prefrontal cortex underlying social anxiety disorder: A multi-channel NIRS study.

Social anxiety disorder (SAD) is characterized by strong fear and anxiety during social interactions. Although ventrolateral prefrontal cortex (VLPFC) activity in response to emotional stimuli is related to pathological anxiety, little is known about the relationship between VLPFC activity and social anxiety. This study aimed to investigate whether VLPFC activity was involved in SAD and whether VLPFC activity was related to the level of social anxiety. Twenty-four drug-naïve patients with SAD and 35 healthy controls underwent near-infrared spectroscopy (NIRS) scanning while performing a verbal fluency task (VFT). Results indicated that, compared to the healthy controls, the SAD patients exhibited smaller changes of oxygenated hemoglobin (oxy-Hb) concentrations in the VLPFC during the VFT. Furthermore, the right VLPFC activation was negatively correlated with social avoidance. In contrast to the latter, the healthy controls exhibited a positive correlation between changes of oxy-Hb concentrations in the bilateral VLPFC and social fear. Our findings provide evidence for VLPFC dysfunction in SAD, and indicate that the VLPFC dysfunction may contribute to the difference between normal and abnormal social anxiety.

Psychosocial difficulties in adolescent and young adult survivors of childhood cancer.

BACKGROUND: With a large number of children surviving cancer worldwide, numerous investigations have assessed psychological and social adjustment among childhood cancer survivors. According to these studies, it is unclear whether childhood cancer survivors successfully adjust to daily life after being discharged from hospital, especially for adolescent and young adult survivors who have unique needs and concerns. The primary aim of this study was to identify the factors underlying psychosocial difficulties faced by adolescent and young adult survivors in their day-to-day lives after being discharged from hospital. METHODS: Semi-structured interviews were conducted. Twenty-five childhood cancer survivors were recruited from two regional cancer institutions in Japan. Content analysis was applied to the responses. RESULTS: Nineteen attributes were extracted and classified into four categories as follows: physical difficulties, interpersonal difficulties, behavioral difficulties, and uncertainty about the future. The attributes indicated by >50% of the participants were "I am worried about not feeling well," "I have difficulty continuing treatment in daily life," "I have difficulty moving my body," "I have to be absent from school or work because of illness," and "I am left behind academically." CONCLUSIONS: This study identified important factors of psychosocial day-to-day difficulties. Clinically, these results suggest that it is important to watch for these signs and to provide early support to survivors so that their daily life and development are not hindered by the treatment and its side-effects, and to offer long-term support focusing on individual patient characteristics such as sex, age, and cancer history.

Constrictive pericarditis caused by immunoglobulin G4-related disease.

An 81-year-old man with congestive heart failure was admitted to our hospital. Computed tomography of the chest revealed pericardial thickening without calcification. Ultrasonic echocardiography and cardiac magnetic resonance imaging demonstrated diastolic dysfunction. Cardiac catheterization showed bilateral elevation of ventricular end-diastolic pressure with a square root sign. The preoperative serum immunoglobulin G4 (IgG4) level was abnormally high. Pericardiectomy and pericardiotomy were considered to be indicated and were performed. Histopathologic examination revealed tissue infiltration by IgG4-positive plasma cells, and constrictive pericarditis caused by IgG4-related disease was diagnosed. Postoperatively, the patient received additional corticosteroid therapy. The latest cardiac magnetic resonance image showed further improvement in diastolic function.

Cognitive behavioral therapy for depression changes medial prefrontal and ventral anterior cingulate cortex activity associated with self-referential processing.

Cognitive behavioral therapy (CBT), an effective treatment for depression, targets self-referential processing of emotional stimuli. We examined the effects of CBT on brain functioning during self-referential processing in depressive patients using functional magnetic resonance imaging (fMRI). Depressive patients (n = 23) and healthy participants (n = 15) underwent fMRI scans during a self-referential task using emotional trait words. The depressive patients had fMRI scans before and after completing a total of 12 weekly sessions of group CBT for depression, whereas the healthy participants underwent fMRI scans 12 weeks apart with no intervention. Before undergoing CBT, the depressive patients showed hyperactivity in the medial prefrontal cortex (MPFC) during self-referential processing of negative words. Following CBT, MPFC and ventral anterior cingulate cortex (vACC) activity during self-referential processing among depressive patients was increased for positive stimuli, whereas it was decreased for negative stimuli. Improvements in depressive symptoms were negatively correlated with vACC activity during self-referential processing of negative stimuli. These results suggest that CBT-related improvements in depressive symptoms are associated with changes in MPFC and vACC activation during self-referential processing of emotional stimuli.

Clinicians' perspectives on support for children with a parent who is diagnosed with breast cancer.

BACKGROUND: There are few data on clinicians' perspectives regarding support for children who have a parent who has been diagnosed with breast cancer. The purpose of this study was to survey the attitudes of physicians and nurses regarding the care of children who had a parent diagnosed with breast cancer. METHODS: A survey was mailed to 898 physicians and 135 nurses who were members of the Japanese Breast Cancer Society in 2009. They were asked to answer questions about their attitudes toward and current practice regarding care for children who had a parent with breast cancer. RESULTS: A total of 340 surveys (284 physicians and 56 nurses) were used in this analysis. The mean age of the respondents was 47.2 years, and their mean number of years of practice was 21.7 years. While 69.1 % of them reported that they felt it important for people in their roles to provide support for children, 84.4 % felt they could not provide sufficient support. The results also suggested that female gender in practitioners and nurses as opposed to doctor status seemed to be associated with preference for intervention, current practice of intervention, and recognition of difficulty to support. CONCLUSIONS: Physicians and nurses express a variety of opinions with regard to support for children with a parent who has breast cancer. It is important to cooperate with other specialists including physicians, nurses, and psychologists and allocate roles appropriately among them to improve outcomes for these children.

The relationship between positive and negative automatic thought and activity in the prefrontal and temporal cortices: a multi-channel near-infrared spectroscopy (NIRS) study.

BACKGROUND: Recently, neurobiological studies of the cognitive model of depression have become vastly more important, and a growing number of such studies are being reported. However, the relationship between the proportion of positive and negative automatic thought and activity in the prefrontal and temporal cortices has not yet been explored. We examined the relationship between brain activity and the proportion of positive and negative automatic thought in patients with major depressive disorder (MDD), using multi-channel near-infrared spectroscopy (NIRS). METHODS: We recruited 75 individuals with MDD (36 females; mean age=39.23 ± 12.49). They completed the Hamilton Rating Scale for Depression, Automatic Thoughts Questionnaire-Revised, Japanese version of the National Adult Reading Test, and the State-Trait Anxiety Inventory. Brain activation was measured by 52-channel NIRS. RESULTS: We found that activation in the vicinity of the right superior temporal gyrus is related to a deviation to negative of the proportion of positive and negative thoughts in individuals with MDD. Left dorsolateral prefrontal cortex activity was higher in the group with comparatively frequent positive thought. LIMITATIONS: Our participants were patients taking antidepressant medication, which is known to influence brain activity. Second, the poor spatial resolution of NIRS increases the difficulty of identifying the measurement position. CONCLUSIONS: We found that activation of the prefrontal and temporal cortices is related to the proportion of automatic thoughts in the cognitive model of depression.

Intramural haematoma should be referred to as thrombosed-type aortic dissection.

OBJECTIVES: Intramural haematoma is defined pathologically as aortic dissection without an intimal tear. We therefore believe that this term is inappropriate as an acute clinical diagnosis, and instead, use the term 'thrombosed-type acute aortic dissection'. We compared the features of thrombosed-type acute aortic dissection with those of classic dissection. METHODS: Thrombosed type was defined as aortic dissection without flow in the false lumen of the aorta on contrast-enhanced computed tomography. Surgery was indicated for all cases of type A acute aortic dissection, and central repair operations were performed in 509 patients. We retrospectively studied these patients' surgical records. RESULTS: Three hundred and forty-four patients (68%) had classic dissection, and 165 (32%) had thrombosed type. Thrombosed type was associated with a significantly higher mean age (69 vs 60 years, P < 0.01), a higher incidence of cardiac tamponade (45 vs 28%, P < 0.01) and a lower incidence of malperfusion (6 vs 35%, P < 0.01) than classic dissection. Entry tears were located in the ascending aorta and the arch in 74 patients (45%) with thrombosed type. Since 2007, an intimal tear has been confirmed intraoperatively or on computed tomography in 39 (78%) of 50 patients with thrombosed-type aortic dissection. Mortality was significantly lower in patients with thrombosed-type dissection (6%) than in those with classic dissection (13%, P = 0.02). CONCLUSIONS: Most cases of intramural haematoma are acute aortic dissections with an intimal tear without re-entry. Intramural haematoma should be referred to as thrombosed-type acute aortic dissection. Thrombosed type can be easily diagnosed on contrast-enhanced computed tomography and has features distinct from those of classic dissection. Our classification may be useful for the diagnosis of these types of aortic dissection.

Acute aortic dissection associated with sleep apnea syndrome.

BACKGROUND: Sleep apnea syndrome (SAS) is an independent risk factor for hypertension which is a major risk factor for acute aortic dissection. The purposes of this study were to assess the prevalence of SAS in patients with acute aortic dissection, delineate the characteristics of patients who have acute aortic dissection with SAS. METHODS: Of 95 consecutive patients with acute aortic dissection, 13 had episodes of sleep apnea and nocturnal hypoxemia. A portable sleep monitoring system was used to assess sleep status in the 13 patients. RESULTS: The SAS-positive group consisted of 12 patients (12.6%), 8 with type A dissection and 4 with type B dissection. Age was significantly lower in the SAS-positive group (47.2 ± 8.5 years) than in the SAS-negative group (64.9 ± 10.3 years)(p <0.001). The male:female ratio was significantly higher in the SAS-positive group than in the SAS-negative group (p <0.001). The body mass index was significantly greater in the SAS-positive group than in the SAS-negative group (p <0.001). All 12 patients in the SAS-positive group had hypertension. CONCLUSIONS: Patients who have acute aortic dissection with SAS are characterized by being tall, fat, and relatively young men with hypertension. Sleep apnea syndrome may be a risk factor for acute aortic dissection in middle-aged men.
