Carcinomatous meningitis from ovarian serous carcinoma: A case report.

Multifocal dissemination of cancer cells from the primary tumor sites to the subarachnoid, pia mater and cerebrospinal fluid (CSF) of the brain and spinal cord causes carcinomatous meningitis (CM). CM is rarely observed in patients with gynecological cancer. The present study described a 59-year-old woman who was diagnosed with CM as a recurrence of stage IIIC ovarian cancer, after presenting with headache and decreased level of consciousness. During adjuvant therapy following surgical debulking, she developed nausea and vomiting. The post-contrast fluid-attenuated inversion-recovery magnetic resonance imaging showed leptomeningeal enhancement on all sulci, particularly around the falx cerebri and cerebellar hemisphere. CM was suspected and CSF cytology revealed adenocarcinoma cells, thus confirming the diagnosis. Overall, although CM is rare, clinicians should be aware of this complication when patients with malignancies experience neurological symptoms, including headache, nausea and vomiting. Knowledge of this clinical entity should assist clinicians in ascertaining accurate diagnoses.

A difficult to diagnose case of low-grade endometrial stromal sarcoma with smooth muscle differentiation treated with laparoscopic surgery: A case report.

Low-grade endometrial stromal sarcoma (LGESS) is a rare uterine tumor, accounting for <1% of all uterine cancer cases. LGESS has several variations and the frequency of tumors exhibiting smooth muscle differentiation is 10-30% of LGESS cases, making such cases even rarer. The present report described the case of a patient with LGESS with smooth muscle differentiation, who was diagnosed as having uterine leiomyoma by preoperative needle biopsy and then underwent laparoscopic surgery. The patient was a 41-year-old woman. MRI findings revealed a diffusely hyperintense uterine tumor on T2-weighted images, thus needle biopsy was performed. This tumor was initially diagnosed as leiomyoma, due to the pathological findings of the biopsied specimen, which possessed tumor cells with spindle-shaped nuclei arranged in a cord and positive immunostaining for smooth muscle actin. The patient was subsequently followed up, and MRI findings after 29 months showed tumor growth. Needle biopsy was performed again and the findings were the same as those of the first biopsy; therefore, this tumor was diagnosed as a leiomyoma and laparoscopic hysterectomy was performed. However, the pathological findings of the excised uterus showed small round tumor cells and CD10 immunostaining positivity, thus the tumor was finally diagnosed as LGESS. The patient requested to be followed up and has shown no signs of recurrence 20 months after surgery. The results of retrospective examination in this case suggested that the presence of regions where only CD10 was positive in immunostaining analysis for SMA and CD10 was useful for needle biopsy diagnosis of LGESS with smooth muscle differentiation.

Uterine metastasis of lobular breast carcinoma under tamoxifen therapy: A case report.

Uterine metastases from breast cancer are uncommon and have rarely been reported in the previous literature. The present report describes the case of a 66-year-old female who developed uterine metastasis 23 years following the primary treatment of invasive breast cancer. Specifically, the patient experienced multiple bone metastases 14 years following primary treatment and had previously been treated with aromatase inhibitors followed by tamoxifen citrate. The patient presented with abnormal genital bleeding and was referred to the Gynecology Department of the Osaka City University Hospital (Osaka, Japan) 23 years following the primary treatment. The results of an endometrial biopsy revealed adenocarcinoma. Initially, it was difficult to differentiate between primary endometrial adenocarcinoma and metastatic adenocarcinoma from breast cancer. The results of pelvic magnetic resonance imaging demonstrated uterine myometrium enlargement and no endometrial thickness. Furthermore, an abdominal total hysterectomy, bilateral salpingo-oophorectomy and a biopsy of the peritoneum were performed. The pathological examination of the resected uterus revealed adenocarcinoma, which proliferated diffusively in the cervical stroma, myometrium, cardinal ligament, bilateral adnexa, omentum and peritoneum. Immunohistochemical results revealed the positive staining of gross cystic disease fluid protein-15, as well as negative staining for CD10 and E-cadherin. Thus, the tumor was diagnosed as metastatic adenocarcinoma from the breast lobular carcinoma. The patient has since been treated with fulvestrant, toremifene citrate and tegafur, and the current patient survival duration is 2 years and 8 months. In conclusion, when patients with breast cancer undergoing hormonal therapy, such as tamoxifen, present with abnormal genital bleeding, future diagnoses should consider both endometrial cancer and uterine metastasis from breast cancer.

Neutrophil-to-lymphocyte ratio is associated with sensitivity to platinum-based chemotherapy and prognosis in patients with advanced serous ovarian carcinoma.

The role of the neutrophil-to-lymphocyte ratio (NLR) in predicting sensitivity to chemotherapy and prognosis has attracted great interest in several types of cancer. In the present study, the correlation between pre-chemotherapy NLR and sensitivity to platinum-based chemotherapy and prognosis in patients with advanced serous ovarian carcinoma was examined by retrospectively reviewing the medical records of 50 patients with stage III-IV serous ovarian carcinoma from 2005 to 2012. Patients were divided into high-NLR (32 patients) and low-NLR (18 patients) groups according to a cutoff value of 2.47. This cutoff was calculated using a receiver operating characteristic (ROC) curve that demonstrated 84% specificity and 60% sensitivity. Patient characteristics, sensitivity to platinum-based chemotherapy and prognosis were subsequently compared. The results revealed no significant difference in patient characteristics between the two groups. In the low-NLR group, 14 of 18 patients (77.8%) were sensitive to platinum-based chemotherapy, whereas 11 of 32 were sensitive in the high-NLR group (34.4%) (P=0.007). Overall and disease-free survival (DFS) were significantly longer in the low-NLR than in the high-NLR group (P=0.013 and P=0.043, respectively). The current results suggested that pre-chemotherapeutical NLR may serve as a biomarker of sensitivity to platinum-based chemotherapy and prognosis in patients with advanced serous ovarian carcinoma.

Self-Reported Cognitive Decline Based on the Ascertain Dementia 8 Questionnaire May Be Effective for Detecting Mild Cognitive Impairment and Dementia in the Community: The Wakuya Project.

INTRODUCTION: To assess cognitive impairment, self-awareness is an important issue. The Ascertain Dementia 8 questionnaire (AD8) is a brief observation checklist for detecting mild cognitive impairment (MCI) and dementia. After analyzing the reliability and validity of a self-reported Japanese version of the AD8 (AD8-J), we compared self- and informant-reported versions of the AD8-J. METHODS: A total of 93 community residents aged 75 years or older living in Wakuya, Northern Japan, agreed to participate in this study; 35 were rated as Clinical Dementia Rating (CDR) 0 (healthy), 46 as CDR 0.5 (defined herein as MCI), and 12 as CDR 1 or above (dementia, confirmed by the DSM-IV). We examined the reliability and validity using a receiver operating characteristic (ROC) curve. We analyzed the differences between self-reported and informant-reported AD8-J using a repeated measures ANOVA. RESULTS: The self-reported AD8-J showed a satisfactory reliability (i.e., Cronbach coefficient, α = 0.71; Guttman split half method coefficient = 0.60). For CDR 0 vs. CDR 0.5 or above, the area under the ROC curve was 0.74 and the cutoff score was 1/2, with a sensitivity of 70.7% and a specificity of 65.7%. Analysis of the subscores of AD8 suggested that, from the early stage of dementia, the subjects showed a subjective decline in memory and interest in hobbies/activities, as well as problems with judgment. CONCLUSION: It is suggested that the self-reported AD8-J was effective in detecting MCI and dementia. We could use it for detecting MCI and dementia, including in those living alone, in the primary health checkup.

Massive ovarian edema with paraovarian cyst torsion treated with laparoscopic surgery: A case report.

Massive ovarian edema is a rare gynecological entity resembling a solid ovarian tumor due to the accumulation of edematous fluid within the ovarian stroma. This condition can be easily mistaken for a neoplasm, resulting in overtreatment by removal of the whole affected ovary. The present study describes the case of a 28-year-old woman who experienced massive ovarian edema with paraovarian cyst torsion treated with laparoscopic surgery. The patient experienced lower abdominal pain lasting for 1 week and visited a local clinic. The ultrasonographic examination revealed two loculated ovarian masses and the patient was then referred to the hospital. Transvaginal ultrasonographic examination revealed a 77.9-mm cystic lesion and a 57.7-mm solid lesion in the left adnexa. A magnetic resonance imaging examination revealed a 55-mm lesion with multiple peripheral ovarian follicles, which was isointense on T1-weighted images and hyperintense on T2-weighted images, and a 75-mm cystic lesion, without a solid component, which was hypointense on T1-weighted images and hyperintense on T2-weighted images in the left adnexa. There were no observed abnormalities of the right adnexa or uterus. Laparoscopic surgery was performed, based on a clinical suspicion of massive ovarian edema with paraovarian cyst torsion. Intraoperatively, a paraovarian cyst was identified in the left adnexa that was twisted 360˚. The size of the enlarged left ovary was reduced to almost normal following the detorsion of the left adnexa. The final diagnosis was that of a massive ovarian edema, which was treated by resecting the paraovarian cyst, while preserving the whole left ovary. The pathological examination of the resected paraovarian cyst revealed a serous cystadenoma. Therefore, the present study suggests that the presence of massive ovarian edema should be taken into consideration when encountering a complex solid ovarian mass with multiple peripheral ovarian follicles, particularly in cases with a history of recurrent abdominal pain.

Does parity matter in women's risk of dementia? A COSMIC collaboration cohort study.

BACKGROUND: Dementia shows sex difference in its epidemiology. Childbirth, a distinctive experience of women, is associated with the risk for various diseases. However, its association with the risk of dementia in women has rarely been studied. METHODS: We harmonized and pooled baseline data from 11 population-based cohorts from 11 countries over 3 continents, including 14,792 women aged 60 years or older. We investigated the association between parity and the risk of dementia using logistic regression models that adjusted for age, educational level, hypertension, diabetes mellitus, and cohort, with additional analyses by region and dementia subtype. RESULTS: Across all cohorts, grand multiparous (5 or more childbirths) women had a 47% greater risk of dementia than primiparous (1 childbirth) women (odds ratio [OR] = 1.47, 95% confidence interval [CI] = 1.10-1.94), while nulliparous (no childbirth) women and women with 2 to 4 childbirths showed a comparable dementia risk to primiparous women. However, there were differences associated with region and dementia subtype. Compared to women with 1 to 4 childbirths, grand multiparous women showed a higher risk of dementia in Europe (OR = 2.99, 95% CI = 1.38-6.47) and Latin America (OR = 1.49, 95% CI = 1.04-2.12), while nulliparous women showed a higher dementia risk in Asia (OR = 2.15, 95% CI = 1.33-3.47). Grand multiparity was associated with 6.9-fold higher risk of vascular dementia in Europe (OR = 6.86, 95% CI = 1.81-26.08), whereas nulliparity was associated with a higher risk of Alzheimer disease (OR = 1.91, 95% CI 1.07-3.39) and non-Alzheimer non-vascular dementia (OR = 3.47, 95% CI = 1.44-8.35) in Asia. CONCLUSION: Parity is associated with women's risk of dementia, though this is not uniform across regions and dementia subtypes.

Word Processing Is Faster than Picture Processing in Alzheimer's Disease.

OBJECTIVE: Alzheimer's disease (AD) is characterized by a slow progressive impairment of episodic memory. Many studies have shown that AD exhibits deterioration of semantic memory during the course of disease progression. We previously reported that AD patients exhibited severe access disorders in the semantic memory system, using the Momentary Presentation Task (20 or 300 ms). In this study, we studied access disorder in patients with AD by the use of object difference (pictures vs words) methods. METHODS: 56 patients with probable AD (NINCDS-ADRDA, mean age 79.0 years) and 11 healthy controls (HC) (mean age 67.0 years) were studied. Ten pictures and 10 corresponding Japanese Hiragana words were presented arbitrarily for 20 and 300 ms on the monitor screen which were correctly named at the usual confrontation setting (i.e., semantic memory preserved). They were asked to name the pictures or to read the words or nonsense syllables aloud. RESULTS: The AD group showed significantly lower scores than the HC group, especially for the 20 ms condition. For the type of stimuli, the AD patients had better performances for words > pictures > nonsense syllables, although no differences for the HC group. The effect of AD severity was noted, moderate > severe stage. CONCLUSIONS: Our results suggested that the processing speed in AD patients may have reduced, even if the semantic memory were preserved. These data indicated that the difference in the processing speeds by the type of stimuli (pictures, words, and nonsense syllables) may be a character of AD patients.

Impaired Eating and Swallowing Function in Older Adults in the Community: The Kurihara Project.

Introduction: Older adults with dementia often develop aspiration pneumonia as a complication due to deterioration of swallowing function. Herein, we report our findings of eating and swallowing-related functions in elderly local residents. Methods: The subjects were 229 elderly residents in Kurihara City, including 97 healthy (Clinical Dementia Rating (CDR): 0), 108 with mild cognitive impairment (MCI) (CDR: 0.5), and 24 with dementia (CDR: 1 or higher: CDR 1+). We analyzed the relationships between the findings, eating, and swallowing, based on the database of the Kurihara Project performed from 2008 to 2010. Results: In the CDR 0.5 group, some deterioration in oral condition, oral function and swallowing function was confirmed. In the CDR 0.5 group, tooth staining, decrease in oral diadochokinesis (oral motion velocity), increased number of points below the cut-off value in a repetitive saliva swallowing test and the questionnaire, and prolonged water swallowing time were confirmed. In the CDR 1+ group, bad breath, elimination of the pharyngeal reflex, increase in disturbed soft palate elevation, and prolonged jelly swallowing time were confirmed. Conclusions: Deterioration of swallowing function was confirmed, even in subjects with mild dementia, in addition to development of problems related to food intake.

Age-related differences in prognosis and prognostic factors among patients with epithelial ovarian cancer.

Approximately 40% of all patients with ovarian cancer in Japan are aged ≥65 years. The aim of the present study was to evaluate the differences in prognosis and prognostic factors between elderly and younger patients with epithelial ovarian cancer. A total of 114 patients with International Federation of Gynecology and Obstetrics (FIGO) stage I-IV ovarian cancer who were initiated on primary treatment at the Osaka City University Hospital (Osaka, Japan) were included in this study. Patient characteristics, treatment outcome and prognosis were compared between elderly (aged ≥65 years) and younger patients, and the prognostic factors associated with overall survival were evaluated by univariate and multivariate analyses. The most common histological type in younger patients was clear cell carcinoma (33.8%) vs. serous carcinoma in elderly patients (44.1%), with a significant difference in the distribution of histological type (P=0.006). Complete resection was achieved in 56.2% of younger patients compared with 32.4% of elderly patients (P=0.03). The rates of standard primary treatment were comparable (56.7% of younger vs. 50.0% of elderly patients). Overall and disease-free survival did not differ significantly between the two groups. Multivariate analyses identified FIGO stage and standard primary therapy as prognostic factors in younger patients and performance status in elderly patients. Age was not an independent significant prognostic factor among patients with ovarian cancer. Therefore, performance status, rather than age, should be considered when selecting the optimal treatment for elderly patients based on objective assessment.

Patients With Very Mild Dementia May Confuse Objective Cognitive Impairments With Subjective Physical Health of Quality of Life: The Tome City Project in Japan.

Many elderly people with cognitive dysfunction may observe a decrease in their health levels and quality of life (QOL). The basic concept of QOL consists of several categories including physical functions and mental health. The QOL domain that is most important for elderly people is physical health and, to a lesser extent, psychological health, social relationships, and/ or the environment. Our aim was to explore the relationships between the subjective measure of QOL, an abbreviated version of the World Health Organization Quality of Life (WHOQOL-BREF) scale, and the objective measure of impairment, Clinical Dementia Rating (CDR), among elderly people in a community. Totally, 178 community dwellers aged 75 years and above agreed to participate and completed the WHOQOL-BREF; 66 (32 males, 34 females) scored a CDR of 0 (healthy), 86 (33, 53) scored a CDR of 0.5 (questionable dementia or very mild dementia), and 26 (12, 14) scored a CDR of 1 and above (dementia). According to Pearson's correlation coefficient analysis (significance level, p < 0.05), the physical domain of the WHOQOL-BREF had significant statistical negative correlations with all CDR subscales. The CDR subscale of memory impairment had a significant statistical negative correlation with the WHOQOL-BREF subscales of the physical (r = -0.151, p = 0.044) and psychological (r = -0.232, p < 0.002) domains. The CDR subscale of home and hobbies impairment had significant statistical negative correlations with all WHOQOL-BREF subscales including the physical (r = -0.226, p = 0.002), psychological (r = -0.226, p = 0.002), social (r = -0.167, p = 0.026), and environmental (r = -0.204, p = 0.006) domains. Patients with very mild dementia may confuse cognitive impairment and physical disabilities. In the future, we need to systematically combine memory clinics and all departments related to the elderly for the successful early detection and rehabilitation of, and long-term care for, dementia.

Examination of the use of needle biopsy to perform laparoscopic surgery safely on uterine smooth muscle tumors.

The warning statement issued by the United States Food and Drug Administration against the use of laparoscopic power morcellators prompted a discussion about the methods of preoperative diagnosis of uterine myometrial lesions. Since 1994, transcervical needle biopsies have been performed to differentiate between uterine leiomyomas and leiomyosarcomas. Needle biopsies are also useful for performing laparoscopic surgery on uterine smooth muscle tumors with histopathological safety. In the present study, data from hematoxylin and eosin (HE)-stained specimens obtained by transcervical needle biopsies from 331 patients with smooth muscle tumors and high intensity regions on T1 weighted images (WI) and/or T2WI from magnetic resonance imaging (MRI) scans were retrospectively examined. From a total of 10 patients with moderate or severe cytological atypia, 4 exhibited smooth muscle tumors of uncertain malignant potential and 6 exhibited leiomyosarcomas. The final diagnosis in 3 patients with ≥10 mitotic figures/high-power field was leiomyosarcoma. A total of 5 patients with coagulative tumor cell necrosis exhibited final diagnoses of leiomyosarcoma. Patients without cytological atypia, mitotic figures or coagulative tumor cell necrosis were not diagnosed with either leiomyosarcomas or smooth muscle tumors of uncertain malignant potential. The present study revealed that laparoscopic surgery is safe when HE-stained specimens obtained by transcervical needle biopsy from areas of high intensity on an MRI scan are negative for all three criteria assessed-cytological atypia, mitotic figures and coagulative tumor cell necrosis.

Fear of Falling and Cognitive Impairments in Elderly People with Hip Fractures.

BACKGROUND/AIM: The purpose of this study was to investigate the estimated prevalence of dementia and the relationship between cognitive impairment and fear of falling in patients with hip fractures. METHODS: Analysis 1 included 100 patients with hip fractures. Analysis 2 included a subgroup of subjects with ≥75 years of functional independence: 46 patients with hip fractures and 46 control subjects without hip fractures, and presence or absence of dementia. We used an informant-rated questionnaire including the AD8 for screening for dementia, the Barthel Index for assessing activities of daily living, and the Short Falls Efficacy Scale-International (FES-I) for assessing fear of falling. RESULTS: The estimated prevalence of dementia was 66% in patients with hip fractures. There were significant fracture and dementia effects, with significant covariate effects of age and gender on the Short FES-I scores. CONCLUSION: Our results suggested that more than two-thirds of patients with hip fractures had dementia. Fear of falling may reflect not only physical functions but also cognitive impairments.

Characterization of Leiomyomatoid Angiomatous Neuroendocrine Tumour (LANT)-like Tumour in the Myometrium with Histopathological Examination.

Leiomyomatoid angiomatous neuroendocrine tumour (LANT) is possibly a new disease entity that was reported as a dimorphic neurosecretory tumour with a leiomyomatous vascular component; it was found in the pituitary. We describe uterine LANT-like malignant tumour in a 45-year-old woman with uterine mesenchymal tumour, diagnosed clinically as uterine leiomyoma. She underwent laparoscopic myomectomy. The tumour consisted of hyalinized vasculature, containing factor VIII-positive endothelium and α-smooth muscle actin-positive vascular smooth muscle cells, and stromal cells, expressing neuroadhesion molecules. Both vascular and stromal components diffusely expressed chromogranin A. Histopathological examinations of uterine LANT-like malignant tumour revealed the common characteristic abnormalities of malignant uterine mesenchymal tumours, i.e. leiomyosarcomas. From our research, defective expression of calponin H1 and proteasome ß9 (PSMB9)/ß1i is observed in uterine LANT-like malignant tumour similarly to immunopathological findings of uterine leiomyosarcoma. These findings meet the definition of uterine LANT-like malignant tumour, and the research findings of our clinical case suggest that LANT is a special type of neuroendocrine neoplasm and is not organ specific.

A retrospective clinical analysis of 5 cases of vaginal melanoma.

Vaginal melanoma is a rare tumor, accounting for <1% of all melanomas and ~1-5% of all vaginal malignant tumors. The prognosis of vaginal melanoma is extremely poor, as it is often resistant to chemotherapy and radiotherapy, and metastases may develop in the early stages of the disease. The present study investigated 5 patients with vaginal melanoma treated at the Department of Gynecology of Osaka City University Hospital (Osaka, Japan) between October, 2000 and April, 2014. All the cases presented with abnormal genital bleeding as the main complaint. Notably, in 3 of the 5 cases the tumors appeared as non-pigmented polyps. Local resection was performed as the primary treatment in all 5 cases. After surgery, dermal injection of interferon ß (feron maintenance therapy) was performed in 3 cases, and dacarbazine, nimustine, vincristine and interferon ß (DAVFeron therapy) was administered in 1 case as adjuvant therapy. All 5 cases recurred within 1 year. The site of recurrence varied, and included the vaginal wall, liver, brain and lung. The median overall survival was 419 days and the median progression-free survival 177 days. In this cohort, all the cases presented with abnormal genital bleeding as the main complaint. Therefore, malignant melanoma of the vagina must be considered along with other gynecological malignancies in patients with abnormal genital bleeding. In this study, over half of the cases had a non-pigmented polypoid lesion of the vagina. Therefore, malignant melanoma of the vagina must be considered when a polypoid lesion is identified on the vaginal wall.

Qualitative Assessment of Instrumental Activities of Daily Living in Older Persons with Very Mild Dementia: The Kurihara Project.

BACKGROUND/AIMS: We investigated quantitative/qualitative changes of instrumental activities of daily living (IADL) in people with a Clinical Dementia Rating (CDR) of 0.5. METHODS: IADLs were evaluated in older residents: CDR of 0 (healthy) and CDR 0.5 (questionable/very mild dementia). The subjects with CDR 0.5 were divided into 2 types: the very mild Alzheimer's disease (vmAD) type and the other type including very mild subcortical vascular dementia. IADLs were evaluated quantitatively using the Lawton and the original qualitative IADL scales. RESULTS: CDR 0.5/vmAD type subjects had impairment of only one Lawton item (Shopping) compared to CDR 0 subjects. However, the CDR 0.5/vmAD type group and the CDR 0.5/other type group showed impairment of 3 items in the qualitative assessment (Shopping, Food preparation, and Mode of transportation). CONCLUSION: We suggest using both quantitative/qualitative IADL scales for assessing older adults with very mild dementia.

Decreased Physical Activity Associated with Executive Dysfunction Correlates with Cognitive Impairment among Older Adults in the Community: A Retrospective Analysis from the Kurihara Project.

BACKGROUND/AIMS: No previous studies have explored the relationship between physical activity (PA) and executive dysfunction. METHODS: We retrospectively evaluated the PA for 590 older participants in the Kurihara Project; 221 participants had a Clinical Dementia Rating (CDR) of 0 (healthy), 295 CDR 0.5 (very mild dementia), and 74 CDR 1+ (dementia). RESULTS: In the complicated task, whether the motor intensity was high (e.g. farming) or low (e.g. shopping), PA exhibited an inverse relationship with the CDR level. By contrast, for simple tasks with high intensity (e.g. walking), no CDR group differences were noted. For PA with low intensity (e.g. cleaning), the CDR 1+ group exhibited decreased levels. CONCLUSION: PA was related to the burden of executive function in patients with mild cognitive impairment; however, in patients with dementia, PA was related to both the burden of executive function and motor intensity.

Pharmacokinetic analyses of carboplatin in a patient with cancer of the fallopian tubes undergoing hemodialysis: A case report.

Opportunities for patients undergoing hemodialysis to receive chemotherapy are increasing. A combination of paclitaxel and carboplatin (TC) is first-line chemotherapy in patients with Müllerian cancer. However, the optimal dose and time interval between the end of carboplatin administration and initiation of hemodialysis remains to be elucidated. TC was administered to a patient with fallopian tube cancer undergoing hemodialysis. The paclitaxel regimen was determined to be 135 mg/m2 (total of 210 mg) over 3 h. After paclitaxel administration, 125 mg of carboplatin was administered over 1 h to achieve a target area under the concentration-time curve (AUC) of 5.0 mg•min/ml using the Calvert formula. The time interval between the end of carboplatin administration and hemodialysis initiation was 1 h at the first cycle, 16 h at the second cycle and 20 h at the third cycle, and the AUC obtained was 2.86, 4.16 and 6.0 mg•min/ml, respectively. The desired AUC of free platinum was demonstrated and only mild side effects were observed at the third cycle. Therefore, hemodialysis was initiated 20 h after completion of carboplatin infusion at cycles 4-6. The total chemotherapy planned was completed without severe adverse events. Measurement of the concentration of free platinum subsequent to administration is useful for determination of the optimal dose of carboplatin and time interval following administration to obtain an adequate AUC. The present study suggests that carboplatin can be administered to a patient undergoing hemodialysis, and that an adequate interval between the end of carboplatin administration and hemodialysis initiation may be ~20 h.

Neuroepidemiologic and Neurobehavioral Characteristics of Motoric Cognitive Risk Syndrome in an Old-Old Population: The Kurihara Project.

BACKGROUND: Recently, the concept of motoric cognitive risk (MCR) syndrome was proposed, where slow gait is considered a risk factor for conversion to dementia. AIM: To retrospectively investigate the characteristics of MCR among a population aged 75+ years, focusing on the aspects of epidemiology and neurobehavioral characteristics. METHOD: The participants were 590 residents aged 75+ years living in Kurihara who underwent MRI and neurobehavioral assessments including walking velocity. The prevalence of MCR and conversion to dementia (AD8 Dementia Screening Interview cutoff 2/8), together with the neurobehavioral characteristics of the MCR group, were analyzed. RESULTS: The prevalence was 11.1%, and the conversion ratio in the MCR group was higher than that in the non-MCR group (OR = 1.38). The MCR group had lower scores on the executive function test as well as gait velocity. CONCLUSIONS: The MCR syndrome increases the rate of conversion to dementia, and both slow gait and lower scores in executive tests, which are 'frontal-based' functions, are predictive of higher rates of conversion to dementia.

The Group Reminiscence Approach Can Increase Self-Awareness of Memory Deficits and Evoke a Life Review in People With Mild Cognitive Impairment: The Kurihara Project Data.

OBJECTIVES: The group reminiscence approach (GRA) and reality orientation (RO) are common psychosocial interventions for patients with dementia. As a qualitative evaluation of the reminiscence approach in patients with dementia, the Patient Report Outcome (PRO) is useful. The purpose of this study was to investigate the effects of GRA-RO for participants with mild cognitive impairment (MCI) using the PRO. DESIGN: A cluster randomized controlled trial. SETTING: Community-based study. PARTICIPANTS: Ninety-four patients with MCI (39 GRA-RO, 23 physical activity, and 32 cognitive training) described their impressions. INTERVENTION: Based on the database of the Kurihara Project, we retrospectively analyzed the participants' descriptions of their impressions as a PRO in the nonpharmacological interventions: GRA-RO, physical activity, and cognitive training. We categorized the descriptions according to the following 2 types: impression with content and reminiscence with life review. We assessed what they wrote regarding memory loss. The content on their life reviews was also a particular focus for the GRA-RO group. MEASUREMENTS: PRO. RESULTS: Compared with the physical activity and the clinical training groups, the GRA-RO patients described their reminiscence with life review and their own memory problems. There was no confusion of the order of events of their autobiographical memories. There was a significant time effect between the 2 family involvement groups in quality-of-life (QOL) scores, and the postintervention QOL scores were significantly better than preintervention. CONCLUSION: This study suggests that the GRA-RO in participants with MCI not only stimulates life review but also increases self-awareness of memory deficits without confusion of the order of events. Thus, the GRA-RO may improve self-esteem and develop self-awareness.
