Discrimination of Frailty Phenotype by KinectTM-Based Stepping Parameters.

Background: Frailty increases the risk of falling, hospitalization, and premature death, necessitating practical early-detection tools. Objectives: To examine the discriminative ability of KinectTM-based stepping parameters for identifying frailty phenotype. Design: Population-based cross-sectional study. Setting: Eighteen neighborhoods near Tokyo Metropolitan Institute for Geriatrics and Gerontology, Itabashi, Tokyo, Japan. Participants: In total, 563 community-dwelling older adults aged ≥75 years without mobility limitations, neurological disease, or dementia were included. Measurements: Step number (SN) and knee total movement distance (KMD) during a 20-s stepping test were evaluated using the KinectTM infrared depth sensor. Results: The number (%) of participants with frailty were 51 (9.1). The area under the receiver operating characteristic curves (95% confidence interval) of a parameter consisting of SN and KMD for frailty was 0.72 (0.64, 0.79). Conclusions: Stepping parameters evaluated using KinectTM provided acceptable ability in identifying frailty phenotype, making it a practical screening tool in primary care and home settings.

Development of Simple, Objective Chair-Standing Assessment of Physical Function in Older Individuals Using a KinectTM Sensor.

BACKGROUND: With increasing interest in addressing quality of life of older individuals, tests such as the Functional Independence Measure (FIM) are widely used measures of infirmity and burden of care. However, these scales are largely qualitative and especially problematic when assessing movement-based tasks. While effective, reliable analysis of human movement is technically complicated and expensive; an infrared depth sensor is potentially a low-cost, portable devise which may provide a quantitative aspect to clinical testing. OBJECTIVE: to assess the utility of the KinectTM sensor in providing an objective evaluation of human movement using an oft measured ADL (chair stand). DESIGN: Cross-sectional study. SETTING: Community, geriatric day-care center in Japan. PARTICIPANTS: Men (n=136) and women (n=266) between 50 and 93 years of age, consisting of healthy (HE; n=312) and physically frail (FR; n= 90) individuals. MEASUREMENTS: Subjects completed two trials of the chair stand, conducted without assistance. Trials were timed and recorded with KinectTM v2. Coronal plane angle (CPA) was determined by a line transecting the shoulder-center and waist relative to the vertical axis and was used to assess quality of the chair stand movement pattern. RESULTS: Age, height, and body mass were not different between groups. CPA was significantly greater in FR (29.3 ± 8.3°) than HE (19.5 ± 6.5°). CPA and age were significantly related (r=0.148, p<0.01). An optimal threshold for CPA identifying frailty was determined by a receiver-operator characteristic curve with a CPA of 23.1° providing the greatest combination of sensitivity (79%) and specificity (73%). CONCLUSION: During the chair stand, frail older adults adopted a forward lean position (increased CPA) compared to healthy older adults. This compensatory posture appears to facilitate torso rotation while reducing lower-limb muscular effort during standing. As such, CPA serves as an indicator of reduced lower-body function in older, frail adults.

Trajectory of criterion symptoms of major depression under newly started antidepressant treatment: sleep disturbances and anergia linger on while suicidal ideas and psychomotor symptoms disappear early.

OBJECTIVE: In modern psychiatry, depression is diagnosed with the diagnostic criteria; however, the trajectory of each of the criterion symptoms is unknown. This study aims to examine this. METHODS: We made repeated assessments of the nine diagnostic criterion symptoms with the Patient Health Questionnaire-9 (PHQ-9) among 2011 participants of a 25-week pragmatic randomised controlled trial of sertraline and/or mirtazapine for hitherto untreated major depressive episodes. The changes from baseline were estimated with the mixed-effects model with repeated measures. The time to disappearance of each symptom was modeled using the Kaplan-Meier survival analysis. RESULTS: The total score on PHQ-9 was 18.5 (SD = 3.9, n = 2011) at baseline, which decreased to 15.3 (5.2, n = 2011) at week 1, to 11.5 (5.9, n = 1953) at week 3, to 7.8 (6.0, n = 1927) at week 9, and to 6.0 (5.9, n = 1910) at week 25. Suicidal ideas, psychomotor symptoms decreased rapidly, while anergia and sleep disturbance also decreased but only slowly. The survival analyses confirmed the primary analyses. CONCLUSIONS: Upon initiation of antidepressant treatment, patients with newly treated major depressive episodes can expect their suicidal ideas and psychomotor symptoms to disappear first but sleep disturbances and anergia to linger on.

Protocol registration and selective outcome reporting in recent psychiatry trials: new antidepressants and cognitive behavioural therapies.

OBJECTIVE: The selective reporting of favorable outcomes has a serious influence on our evidence base. However, this problem has not yet been systematically investigated in the field of psychiatry. Our study aimed to evaluate registration and outcome reporting in randomized controlled trials (RCTs) of standard treatments for depression: cognitive behavioural therapy (CBT) or new-generation antidepressants (ADs). METHOD: We searched for reports of RCTs examining the efficacy of CBT or AD for depression that were published between 2011 and 2013. We then compared their primary outcomes in the trial registries and those in publications. RESULTS: We identified 170 trials. Among them, 92 trials (54.1%) were registered, 43 trials (25.3%) were properly registered, and only 32 (18.8%) trials were both properly registered and reported (the primary outcomes as recorded in the registries were reported in publications). There was no statistically significant difference in the proportions of properly registered and reported trials for CBT or AD (relative risk: 0.51, 95% CI: 0.25-1.03). High impact factor journals, commercial funding, publication of protocol, and relatively large sample size were significant predictors of proper registration and reporting. CONCLUSION: The prevalence of proper registration and reporting is still very low in depression trials.

Importance of platinum-free interval in second-line chemotherapy for advanced or recurrent endometrial cancer.

PURPOSE: To investigate the effectiveness of platinum-based combination chemotherapy as second-line chemotherapy for patients with advanced or recurrent endometrial cancer treated initially by platinum-based combination chemotherapy. MATERIALS AND METHODS: Subjects were patients who had received platinum-based combination chemotherapy as second-line chemotherapy: 56 patients with recurrent disease who had previously received postoperative adjuvant platinum-based combination chemotherapy (Category 1) and 21 patients who had received first-line chemotherapy but not adjuvant chemotherapy for advanced or recurrent disease (Category 2). Patients' records were searched for the response to second-line chemotherapy and survival, particularly in relation to the platinum-free interval (PFI). RESULTS: APFI over 12 months was a predictor of response (64.7%) and overall survival time (23 months) in Category 1 patients. A PFI of less than three months was a negative predictor of response (0%) and overall survival (nine months) in Category 2 patients. CONCLUSION: Platinum-based combination chemotherapy appears to be effective as second-line chemotherapy for endometrial cancer if the PFI is sufficiently long.

Impact of multimodal therapy on the survival of patients with newly diagnosed uterine carcinosarcoma.

PURPOSE: To investigate treatment outcomes of uterine carcinosarcoma (CS) patients who underwent complete surgical resection of all visible disease and platinum-based adjuvant chemotherapy (multimodal therapy). MATERIALS AND METHODS: The authors reviewed 127 uterine CS patients treated at this institution from 1990 to 2010. They operated 123 patients in clinical Stages 1-3, 97 of which underwent complete resection and systemic lymphadenectomy. RESULTS: A total of 97 patients (FIGO 2008: Stage 1 in 50 patients, Stage 2 in six, Stage 3 in 37, and Stage 4 in four) underwent surgical staging, 74 of which were administered five cycles (median) of platinum-based adjuvant chemotherapy. The median overall survival (OS) associated with multimodal therapy 50.6 months compared with 34.9 months incomplete multimodal therapy. After multimodal treatment, 32.9% (32/97) patients showed recurrence (24/32 hematogenous). CONCLUSION: Multimodal therapy increased survival among uterine CS patients, but the recurrence rate remained high. Further consideration of treatment options for uterine CS is required.

Enhanced Needle Visualization: advantages and indications of an ultrasound software package.

The ultrasound software package Enhanced Needle Visualization (ENV) has been reported to provide improved ultrasound imaging of needles even at steep insertion angles. ENV has three settings: shallow, medium and steep. However, the angles are unknown. We examined the advantages and indications of ENV in an in vitro study. A 22-gauge needle was inserted into pork meat using the in-plane technique. The needle was positioned at zero, 30, 45 and 60 degree angles, and 1, 2, 3 and 4 cm in-depth from the probe. The ultrasound visibility in each ENV setting was objectively evaluated and graded as 'not visible', 'poor', 'visible', 'good' and 'excellent' in ascending order. At zero degrees we found no advantage of ENV. At 30 degrees, the needle exhibited better visibility with 'good' or above grade in the shallow setting at all depths and in the medium setting at depths of 1, 2 and 3 cm than in the off position. At 45 degrees, needle visibility significantly increased from 'not visible' in the off position to 'visible' or above in the steep settings at depths of 1, 2 and 3 cm. At 60 degrees the objective visibility was 'not visible' in the off position and significantly increased to 'poor' in the steep setting. We recommend selecting the shallow setting for needles with an insertion angle of 30 degrees and the steep setting for 45 degrees within the advantageous area. This technique may allow safer ultrasound procedures for various unprecedented approaches.

Second-line chemotherapy for carboplatin/paclitaxel-refractory ovarian cancer: are multi-agent chemotherapies of little value truly?

PURPOSE: We examined whether second-line multi-agent chemotherapies are of any value for carboplatin/paclitaxel (TC)-refractory ovarian cancer. METHODS: Subjects included 60 patients with ovarian, peritoneal, or tubal carcinoma who received second-line platinum-based combination chemotherapy. Thirty-nine were treated with irinotecan/cisplatin or nedaplatin and 21 with docetaxel/cisplatin shortly after TC failure. Patients were divided between those who were refractory to initial platinum-based chemotherapy (n = 29, Group A) and those who were platinum-sensitive (n = 31, Group B). Efficacy and safety of the combination chemotherapies were compared between the two groups. RESULTS: Response to the combination chemotherapy was 10.3% in Group A and 41.9% in Group B. Median time to disease progression was 4.02 months and 7.21 months, respectively (p = 0.006), and median survival time was 7.89 months and 9.23 months, respectively (p = 0.003). There was no difference in response between the two regimens. Grade 3-4 hematologic toxicities were more frequent with the docetaxel regimen. CONCLUSION: The choice between agents for second-line chemotherapy for TC-refractory ovarian cancer should be based on whether the cancer was previously platinum-sensitive. With a history of such response, multi-agent chemotherapies are worth considering after TC failure. With no previous response, the expected efficacy of second-line multi-agent chemotherapy is low, suggesting the use of monochemotherapy.

The treatment of uterine leiomyosarcoma: clinical outcomes of 18 cases and the effectiveness of chemotherapy.

PURPOSE: To investigate clinical outcomes with respect to the effectiveness of chemotherapy in the treatment of uterine leiomyosarcoma. METHODS: Study subjects were 18 patients with uterine leiomyosarcoma treated surgically at our hospital between February 1986 and December 2007. A chemotherapy regimen that combined ifosfamide, epirubicine, and cisplatin (IEP) was used as the main first-line chemotherapy. RESULTS: FIGO disease stages were as follows: Stage I (n = 11), Stage II (n = 1), Stage III (n = 3), Stage IV (n = 3). Five-year overall survival of patients with Stage I-III disease was 65.3% (95% CI: 46.1-92.4%). None of patients with Stage IV disease survived for more than two years. Of seven patients who suffered advanced or recurrent disease, six received IEP; the response rate was 50%, one complete response and two partial responses. CONCLUSIONS: The combination of surgery and chemotherapy seems to be an acceptable treatment for uterine leiomyosarcoma. IEP may be an active regimen for this aggressive disease.

Clinical features of 215 stage I ovarian tumors in Japanese women.

PURPOSE: Differences of the clinical features of Stage I borderline ovarian tumors and Stage I ovarian cancer need to be clarified. METHODS: We retrospectively investigated 215 patients with Stage I ovarian tumors (67 with borderline tumors and 148 with ovarian cancer) treated between 1988 and 2001. RESULTS: Only one patient with a borderline tumor developed recurrence, while recurrence was found in 20 patients with Stage I ovarian cancer. There was a significant difference in the recurrence rate between patients with Stage Ia or Ib ovarian cancer and those with Stage Ic cancer (p = 0.007). Clear cell adenocarcinoma showed a higher recurrence rate. Among our patients with recurrence, only five in whom the recurrent tumor could be surgically resected are currently alive and disease-free. CONCLUSIONS: This study confirmed the low aggressiveness of Stage I borderline ovarian tumors and high aggressiveness of Stage Ic ovarian cancer or clear cell adenocarcinoma. In patients with recurrence, surgical resection may improve survival.

Evaluation of the therapeutic results of epiduroscopic adhesiolysis for failed back surgery syndrome.

BACKGROUND: No data for patients with failed back surgery syndrome (FBSS) based on the location of adhesions separated by epiduroscopic adhesiolysis have been reported. METHODS: We performed epiduroscopic adhesiolysis on 28 FBSS patients to examine the impact of differences in the locations of the separated regions on the treatment results. We performed fluoroscopic imaging through the sacral hiatus to assess the condition of adhesions in the epidural space during the post-adhesiolysis observation period. RESULTS: In patients in whom only the epidural space was separated by adhesiolysis, there was a significant improvement in the Roland-Morris disability questionnaire (RDQ) score until 12 weeks after adhesiolysis, but the score gradually returned to the preoperative value thereafter. Among patients in whom the nerve root responsible for radicular pain was separated, there was a long-term improvement in the RDQ, Oswestry disability index 2.0 (ODI), and Japanese Orthopedic Association Assessment of Treatment (JOA) scores. Among patients in whom both the epidural space and the nerve root responsible for pain were separated, there was a 12 week improvement in the RDQ score and 24 week improvements in the ODI and JOA scores. CONCLUSIONS: Progressive epidural imaging after adhesiolysis suggested that pain was caused by re-adhesion around the nerve root. Since re-adhesion of the nerve root required some time, the effect of adhesiolysis was maintained for extended periods in these cases. We suggest that epiduroscopic adhesiolysis is an effective therapy for FBSS patients, and that adhesiolysis of the nerve root may exhibit the long-term (24 weeks) efficacy in patients with pain.

New diagnostic reporting format for endometrial cytology based on cytoarchitectural criteria.

OBJECTIVE: The aim of this study was to develop a new reporting format for endometrial cytology that would standardize the diagnostic criteria and the terminology used for reporting. METHODS: In previous studies, cytoarchitectural criteria were found to be useful for the cytological assessment of endometrial lesions. To apply these criteria, an appropriate cytological specimen is imperative. In this article, the requirements of an adequate endometrial cytological specimen for the new diagnostic criteria are first discussed. Then, the diagnostic criteria, standardized on a combination of conventional and cytoarchitectural criteria, are presented. Third, terminology that could be used, not only for reporting the histopathological diagnosis, but also for providing better guidance for the gynaecologist to determine further clinical action, is introduced. The proposed reporting format was investigated using endometrial cytology of 58 cases that were cytologically underestimated or overestimated compared to the histopathological diagnosis made on the subsequent endometrial biopsy or surgical specimens. RESULTS: Of the 58 cases, 12 were reassessed as being unsatisfactory for evaluation. Among the remaining 46 cases, 25 of the 27 cases, which had been underestimated and subsequently diagnosed as having endometrial carcinoma or a precursor stage on histopathological examination,were reassessed as recommended for endometrial biopsy. On the other hand, 19 cases overestimated by cytology were all reassessed as not requiring biopsy. CONCLUSIONS: The reporting format for endometrial cytology proposed in this article may improve diagnostic accuracy and reduce the number of patients managed inappropriately.

Adjuvant hysterectomy for treatment of residual disease in patients with cervical cancer treated with radiation therapy.

The objective of this retrospective study was to determine the efficacy of adjuvant hysterectomy for treatment of residual disease in cervical carcinoma treated with radiation therapy. Between 1971 and 1996, 1590 patients with carcinoma of the uterine cervix (stages I-IIIb) were treated with radiation therapy. Three months after completion of radiation therapy, the status of local control was investigated, and total abdominal hysterectomy was performed in cases in which central residual disease existed in the cervix. Of the 1590 patients, residual disease was identified in 162 patients. Among these patients, 35 showed an absence of distant metastasis or lateral parametrial invasion and underwent hysterectomy. The overall 5- and 10-year survival rates for these patients were 68.6 and 65.7%, respectively. There was no significant difference in survival between patients with squamous cell carcinoma and those with non-squamous cell carcinoma or between patients with stage I/II carcinoma and those with stage III carcinoma. With respect to treatment-related morbidity, five (14.3%) patients suffered grade III or IV complications after hysterectomy. Adjuvant hysterectomy is an effective addition to radiation therapy in the treatment of cervical cancer, even in patients with stage III disease and in those with non-squamous cell carcinoma.

Treatment of squamous cell carcinoma of the uterine cervix with radiation therapy alone: long-term survival, late complications, and incidence of second cancers.

The objective of this retrospective study was to determine the survival rate, incidence of late complications, and incidence of second cancers when radiation therapy alone is used for carcinoma of the uterine cervix. Between 1971 and 1995, 1495 patients with squamous cell carcinoma of the uterine cervix (stages I-IV) were treated with radiation therapy alone in our hospital. Radiation therapy consisted of a combination of high-dose-rate intracavitary brachytherapy and external beam radiotherapy. The cumulative 5-year survival rates for stages Ib, II, and III/IVa carcinoma were 93.5, 77.0, and 60.3%, respectively, and the 10-year survival rates were 90.9, 74.5, and 56.1%, respectively. Local control rates for stages Ib, II, and III/IVa carcinoma were 92.0, 79.4 and 64.2%, respectively. Eighty-two (5.5%) patients suffered grade III/IV or V (fatal) complications. A second cancer developed in 13 (0.87%) patients. Second cancers were observed most frequently in the rectum (five cases), colon (three cases), and uterine body (two cases). Long-term follow-up data revealed that our method of radiation therapy alone for locally advanced carcinoma of the uterine cervix is effective, with low incidences of late complications and second cancers.

Peripheral primitive neuroectodermal tumor of the vulva: report of a case with imprint cytology.

BACKGROUND: Peripheral primitive neuroectodermal tumor (PNET) of the vulva is an extremely rare disease, and, to our knowledge, only two cases have been previously reported. CASE: A 45-year-old woman presented with a mass in the right labium major. Three years after removal of the tumor, she noticed a new lesion in the same place and underwent a partial vulvectomy. The imprint cytology of the recurrent tumor showed a monomorphic appearance, composed of small round cells with scant cytoplasm against a hemorrhagic background. These tumor cells were loosely connective, but rosettelike structures were observed focally. On pathologic examination, the neoplasm was composed of small round tumor cells showing sinusoidal, diffuse or micropapillary growth. Immunohistochemically, the neoplastic cells stained positively for neuron-specific enolase, vimentin and HBA 71 and negatively for cytokeratin, HBA 45 and muscle-specific actin. The morphologic characteristics of the disease were well expressed in the imprint cytology, and this influenced the selection of immunohistochemical studies. CONCLUSION: Cytologic examination for vulvar tumors, even imprint cytology, can be a useful tool in obtaining an accurate pathologic diagnosis of a rare disease, such as peripheral PNET.

Identification of a high-risk subgroup in cytology-positive stage IIIA endometrial cancer.

OBJECTIVE: To identify a high-risk subgroup among patients with cytology-positive stage IIIA endometrial cancer. STUDY DESIGN: Fifty-four stage IIIA endometrial cancer patients who were positive only on peritoneal cytology were divided into two groups based on the cytologic pattern of their peritoneal smears. In group A, malignant cell clusters had well-defined edges, while the tumor cell clusters had scalloped edges in group B. The prognostic significance of these findings was investigated. RESULTS: The five-year disease-free survival rate was 97.5% in group A (n=40) versus 50% in group B (n = 14). Multivariate analysis confirmed that the cytologic pattern had an independent influence on survival. CONCLUSION: Positive peritoneal cytology composed of malignant cell clusters with well-defined edges has no impact on survival. Only endometrial cancer patients who show tumor cell clusters with scalloped edges in peritoneal smears are worth considering for upstaging.

Positive peritoneal cytology in endometrial cancer: enhancement of other prognostic indicators.

OBJECTIVE: The goal of this study was to investigate the prognostic significance of positive peritoneal cytology in endometrial cancer. METHODS: A clinicocytopathological study was performed in 534 patients with endometrial cancer to assess the prognostic value of positive peritoneal cytology. The study population was divided into three groups: a low-risk group (disease limited to the uterus, grade 1, and depth of invasion < or =1/2), a moderate-risk group (disease limited to the uterus, grade 2 or 3, and/or depth of invasion >1/2), and a high-risk group (extrauterine disease). In each group, disease-free survival was compared in the patients who were positive or negative for malignant cells. RESULTS: The overall incidence of positive peritoneal cytology was 22.3% (119/534). The 5-year disease-free survival of patients positive or negative for malignant cells was 98.1% versus 100% in the low-risk group (n = 250), 77.5% versus 91.3% in the moderate-risk group (n = 211), and 42.9% versus 72.1% in the high-risk group (n = 73). A significant difference was noted in the moderate-risk (P = 0.044) and high-risk (P = 0.015) groups, but not in the low-risk group (P = 0.56). CONCLUSIONS: Positive peritoneal cytology is not a negative prognostic indicator itself, but it potentiates other prognostic indicators for endometrial cancer. Our findings also suggest that patients with positive peritoneal cytology in the absence of other adverse prognostic factors do not need upstaging.

Müllerian adenosarcoma of the uterus: report of a case with imprint cytology.

BACKGROUND: Müllerian adenosarcoma is a rare morphologic variant of uterine sarcoma that, although well described histologically, is scarcely mentioned in the cytologic literature. CASE: A 75-year-old female was suspected of having atypical endometrial hyperplasia on an endometrial smear. However, subsequent imaging techniques revealed the presence of a bulky, polypoid mass filling the uterine cavity. On pathologic examination of the hysterectomy specimen, the polypoid tumor was diagnosed as mullerian adenosarcoma, homologous, with sarcomatous overgrowth, in which the sarcomatous component was compatible with high grade endometrial stromal sarcoma. Imprint smears of the tumor consisted of two morphologic patterns, sarcomatous and glandular. The sarcomatous tumor cells, with coarse chromatin and relatively scant cytoplasm, formed small aggregates or appeared alone. These cells were semiround or oval and had conspicuous nucleoli. In addition to these observations, small and large clusters of glandular cells with mild atypism were interspersed with the sarcomatous cells. CONCLUSION: Cytologic examination of müllerian adenosarcoma well reflects its pathologic features.

Malignant potential of positive peritoneal cytology in endometrial cancer.

OBJECTIVE: To investigate the malignant potential of positive peritoneal cytology in endometrial cancer. METHODS: Fifty patients with clinical stage I-II endometrial cancer in whom the disease was completely surgically resected and positive peritoneal smears were found at surgery formed the study population. In these patients, a tube for cytologic analyses was inserted into the peritoneal cavity when closing the abdomen. The peritoneal cavity was irrigated with physiologic saline, and washings were obtained through the tube 7 and 14 days after the operation. RESULTS: Persistence of positive peritoneal cytology was observed in four of seven patients with adnexal metastasis, zero of nine patients with nodal disease, and one of 34 patients with disease confined to the uterus, for a total of 10% (5 of 50). In the remaining 45 (90%) patients, no malignant cells were found in any of the washings. CONCLUSION: The current series suggests that endometrial cancer cells found in the peritoneal cavity usually disappear within a short time and seem to have a low malignant potential. It also seems that only malignant cells from special cases, such as adnexal metastasis, may be capable of independent growth, and are possibly associated with intraperitoneal recurrence.

Effects of increasing expenditure of energy during exercise on psychological well-being in older adults.

The purpose of present study was to examine the effects on psychological well-being of energy expended as a result of the exercise intervention. 33 older adults (M age=68.6 yr., SD=4.7) participated in three supervised water-based exercise sessions per week for 12 wk. Based on the relative changes in daily energy expenditure as measured by questionnaire between pre- and posttraining, the subjects were split into three groups. This classified each subject as either having experienced a relatively low change (n=11), moderate change (n= 11), or high change (n= 11) in daily energy expenditure. Our data showed that the group with the greater increase in energy expenditure as a result of exercise, when compared pre- and posttraining, improved only on Depression-Dejection on the Profile of Mood States more than did the group with low change. Consequently, we concluded that the amount of energy expended was partially related to improvement in psychological well-being.
