Effects of a new speech support application on intensive speech therapy and changes in functional brain connectivity in patients with post-stroke aphasia.

Aphasia is a language disorder that occurs after a stroke and impairs listening, speaking, reading, writing, and calculation skills. Patients with post-stroke aphasia in Japan are increasing due to population aging and the advancement of medical treatment. Opportunities for adequate speech therapy in chronic stroke are limited due to time constraints. Recent studies have reported that intensive speech therapy for a short period of time or continuous speech therapy using high-tech equipment, including speech applications (apps, can improve aphasia even in the chronic stage. However, its underlying mechanism for improving language function and its effect on other cognitive functions remains unclear. In the present study, we investigated whether intensive speech therapy using a newly developed speech support app could improve aphasia and other cognitive functions in patients with chronic stroke. Furthermore, we examined whether it can alter the brain network related to language and other cortical areas. Thus, we conducted a prospective, single-comparison study to examine the effects of a new speech support app on language and cognitive functions and used resting state functional MRI (rs-fMRI) regions of interest (ROI) to ROI analysis to determine changes in the related brain network. Two patients with chronic stroke participated in this study. They used the independent speech therapy system to perform eight sets of 20 randomly presented words/time (taking approximately 20 min), for 8 consecutive weeks. Their language, higher cognitive functions including attention function, and rs-fMRI, were evaluated before and after the rehabilitation intervention using the speech support app. Both patients had improved pronunciation, daily conversational situations, and attention. The rs-fMRI analysis showed increased functional connectivity of brain regions associated with language and attention related areas. Our results show that intensive speech therapy using this speech support app can improve language and attention functions even in the chronic stage of stroke, and may be a useful tool for patients with aphasia. In the future, we will conduct longitudinal studies with larger numbers of patients, which we hope will continue the trends seen in the current study, and provide even stronger evidence for the usefulness of this new speech support app.

[A case of conduction aphasia with specific jargon utterance].

We report a patient with bilateral hemispheric lesions caused by two episodes of cerebral infarction who exhibited conduction aphasia with unique jargon. The patient was an 84-year-old, right-handed man. Beginning after the second episode of cerebral infarction (defined as the time of symptom onset), neologistic jargon and an iterative pattern of phonemic variation became prominent, whereas phonological paraphasia and conduite d'approche were observed in the patient's overall speech. Therefore, the aphasia was characterized by the combination of conduction aphasia and neologistic jargon. At 27 months after symptom onset, the neologisms and iterative pattern of phonemic variation had disappeared, but a wide variety of phonological paraphasia and conduite d'approche persisted, clarifying the pathological features of the conduction aphasia experienced by this patient. The conduction theory (Kertesz et al., 1970) provides a convincing explanation for the mechanism of the onset of neologisms in the present case. Thus, we propose the existence of a symptomatic relationship between neologisms and phonological paraphasia.

Prediction of Postoperative Delirium after Gastrointestinal Surgery Using the Mie Constructional Apraxia Scale.

BACKGROUND: Postoperative delirium (POD) is a transient postoperative complication that occurs after surgical procedures. Risk factors reported for POD include dementia and cognitive decline. The purpose of this study was to identify predictors of POD by examining the use of preoperative neuropsychological tests, including the Mie Constructional Apraxia Scale (MCAS), and patient background factors. METHOD: The study was performed as a retrospective cohort study. The subjects were 33 patients (mean age, 75.8 ± 10.9 years; male:female ratio, 26:7) who underwent gastrointestinal surgery at Matsusaka City Hospital between December 2019 and April 2021. Data were collected retrospectively from medical records. The study was started after receiving approval from the institution's ethics committee. The survey items included general patient information, nutritional assessment, surgical information, and neuropsychological tests. Subjects were classified into 2 groups according to the presence or absence of POD. If a significant difference was observed between the 2 groups, the sensitivity, specificity, and area under the curve were calculated using a receiver operating characteristic (ROC) curve. RESULT: There were 10 patients in the POD group (male:female ratio, 6:4) and 23 patients in the non-POD group (20:3). The POD group had a shorter education history (p = 0.047) and significantly higher MCAS scores (p = 0.007) than the non-POD group. The ROC curve showed a sensitivity of 90%, a specificity of 69%, and an area under the curve of 0.798 when the MCAS cutoff value was set at 3 points. CONCLUSION: Preoperative MCAS results were capable of predicting the occurrence of POD after gastrointestinal surgery. In addition, a relatively short education background was also considered a risk factor for POD.

Endometrioid carcinoma arising from diaphragmatic endometriosis treated with laparoscopy: A case report.

Malignant transformation of diaphragmatic endometriosis is rare. We present a case of endometrioid carcinoma arising from diaphragmatic endometriosis treated with laparoscopy. A 59-year-old primigravida woman who had undergone abdominal hysterectomy for adenomyosis at the age of 47 years was referred to our hospital for investigation of a tumor on the surface of the liver. An integrated positron emission tomography-computed tomography scan revealed a 3-cm nodule on the surface of the liver with abnormal fluorine-18-deoxyglucose accumulation. Partial resection of the diaphragm and liver was performed. Histopathological examination revealed an endometrioid carcinoma arising from diaphragmatic endometriosis. We additionally performed laparoscopic bilateral salpingo-oophorectomy and partial omentectomy. The resected tissues revealed no malignancy. Adjuvant chemotherapy with paclitaxel and carboplatin was administered. In cases of diaphragmatic tumors, endometriosis and its associated malignancies should be considered. Laparoscopic surgery is effective in patients with such conditions.

Extranodal marginal zone lymphoma of the uterine cervix with concomitant copy number gains of the MALT1 and BCL2 genes: A case report.

Extranodal marginal zone lymphoma (EMZL) of mucosa-associated lymphoid tissue (MALT) of the uterus is rare, and the etiology, pathophysiology and cytogenetic features remain unknown at present. The present study reports a case of a 71-year-old female with EMZL of the uterine cervix that was 80 mm in diameter and invaded directly into the rectal serosa. Complete remission was successfully induced by 6 courses of immunochemotherapy with rituximab plus cyclophosphamide, doxorubicin, vincristine and prednisolone. Although the metaphase spread of the tumor cells was unavailable for whole cytogenetic analysis, fluorescence in situ hybridization (FISH) detected triple signals for MALT1 and B-cell lymphoma 2, located at chromosome 18q21, and the centromere of chromosome 18, which was suggestive of trisomy 18, and in combination with previous studies, suggested a possible association between trisomy 18 and the large tumor at initial presentation in the present patient. In addition, FISH examination detected immunoglobulin heavy chain gene rearrangement, although the translocation partner was unconfirmed. A total of 18 previously-studied patients with EMZL of the uterus, including that of the present study, were reviewed with respect to their clinical features and treatment and cytogenetic abnormality. In the evaluation of the English scientific literature, this is the first reported patient with EMZL of the uterus with partly determined cytogenetic abnormalities.

Isolated fallopian tube torsion diagnosed and treated with laparoscopic surgery: A case report.

Among diseases causing acute lower abdominal pain in women, isolated fallopian tube torsion is very rare, with an annual prevalence of 1 in 1.5 million. Because it has fewer findings on imaging compared to adnexal torsion, the correct diagnosis can rarely be made before an operation. We present a case of isolated fallopian tube torsion that was suspected preoperatively by its clinical course and findings on computed tomography. A 24-year-old woman repeatedly experienced acute colicky pain in the right lower back. Transvaginal ultrasonography and magnetic resonance imaging showed a right pelvic cystic lesion with intact ovaries; these findings led us to schedule a laparoscopic examination. However, the patient presented to the emergency room with acute severe right back pain. The preoperative diagnosis considering the computed tomography findings and clinical course was consistent with fallopian tube torsion. An earlier diagnosis may have helped to preserve the fallopian tube and future fertility.

Effects of drospirenone on adhesion molecule expression and monocyte adherence in human endothelial cells.

OBJECTIVE: A major concern in hormone replacement therapy is the associated increased risk of cardiovascular diseases. A progestogen without the unfavorable effects on cardiovascular disease should be explored. Monocyte adhesion to endothelial cells is an important initial event in atherosclerosis. In this study, the effects of the alternative progestogen drospirenone (DRSP) on monocyte adhesion in human umbilical venous endothelial cells (HUVECs) were examined. STUDY DESIGN: In HUVECs treated with estrogens and progestogens, including DRSP and medroxyprogesterone acetate (MPA), the expression of the adhesion molecules E-selectin, P-selectin, ICAM-1, and VCAM-1 were examined by real-time PCR and using an enzyme-linked immunosorbent assay. A flow chamber system was used to investigate the effects of DRSP on U937 monocytoid cell adherence to HUVEC monolayers. All experimental data were compared using one-way Analysis of Variance. RESULTS: Upregulation of adhesion molecule mRNA or protein was not seen in HUVECs treated with DRSP alone or with 17ß-estradiol+DRSP. DRSP alone, 17ß-estradiol+DRSP or ethinylestradiol+DRSP did not increase the number of adherent monocytoid cells to HUVECs in the flow chamber system. However, MPA significantly enhanced the monocytoid cell adherence (P<0.05). CONCLUSIONS: DRSP did not increase the expression of adhesion molecules or monocytoid cell adherence to endothelial cells, indicating that DRSP could reduce the risk of atherogenesis caused by MPA. These results suggest that DRSP may be an alternative to MPA in hormone replacement therapy.

Relationships among Communication Self-Efficacy, Communication Burden, and the Mental Health of the Families of Persons with Aphasia.

BACKGROUND: The purpose of this study was to elucidate the relationships among communication self-efficacy (SE), communication burden, and the mental health of the families of persons with aphasia using structural equation modeling (SEM). METHODS: This study examined 110 pairs of persons with aphasia receiving home care and 1 family caregiver per person with aphasia. The survey items for this study consisted of the Communication Self-efficacy Scale, the Communication Burden Scale, the Geriatric Depression Scale-Short Form-Japanese, and the Health-Related Quality of Life: SF-8 Health Survey. The relationships between the constructive concept of "communication self-efficacy" and "communication burden," and "mental-health status" were analyzed using SEM. RESULTS: The results of the SEM analysis revealed that a high communication SE of the families was associated with low burden of communication and good mental-health status. CONCLUSIONS: Psychoeducational programs that address the communication SE of family caregivers may have the potential to reduce the burden of communication and to improve the mental health of caregivers. These programs could lead to an enhanced quality of life for both persons with aphasia and their families.

Pure agraphia after infarction in the superior and middle portions of the left precentral gyrus: Dissociation between Kanji and Kana.

The present study describes a Japanese patient with pure agraphia displaying differential disturbances in processing Kanji (morphogram) and Kana (syllabogram) letters after an infarction in the middle and superior portions of the left precentral gyrus. Kana errors reflected the patient's difficulty with retrieving both motor and visual letter images, whereas Kanji errors included partial letter stroke omissions or additions. This present case suggests that differences in writing disturbances between Kana and Kanji letters are caused by a differential dependency on letter motor images.

Japanese Adaptation of the Stroke and Aphasia Quality of Life Scale-39 (SAQOL-39): Comparative Study among Different Types of Aphasia.

BACKGROUND: We have developed a Japanese version of the Stroke and Aphasia Quality of Life Scale-39 (SAQOL-39), designated as SAQOL-39-J, and used psychometric methods to examine its acceptability and reliability. METHODS: The acceptability and reliability of SAQOL-39-J, which was developed from the English version using a standard translation and back-translation method, were examined in 54 aphasia patients using standard psychometric methods. The acceptability and reliability of SAQOL-39-J were then compared among patients with different types of aphasia. RESULTS: SAQOL-39-J showed good acceptability, internal consistency (Cronbach's α score = .90), and test-retest reliability (intraclass correlation coefficient = .97). Broca's aphasia patients showed the lowest total scores and communication scores on SAQOL-39-J. CONCLUSIONS: The Japanese version of SAQOL-39, SAQOL-39-J, provides acceptable and reliable data in Japanese stroke patients with aphasia. Among different types of aphasia, Broca's aphasia patients had the lowest total and communication SAQOL-39-J scores. Further studies are needed to assess the effectiveness of health care interventions on health-related quality of life in this population.

Medroxyprogesterone acetate enhances monocyte-endothelial interaction under flow conditions by stimulating the expression of cell adhesion molecules.

CONTEXT: Monocyte adhesion to endothelial cells is an important initial event in atherosclerosis and is partially mediated by adhesion molecule expression on the cell surface. Although estrogens inhibit atherosclerosis development, effects of coadministered progestogen remain controversial. OBJECTIVE: We examined the effects of progestogen on cytokine-stimulated human umbilical venous endothelial cell (HUVEC) expression of adhesion molecules. DESIGN: In HUVECs, adhesion molecule mRNA levels were measured by real-time PCR. Protein expression was quantified by immunocytochemistry and ELISAs. To mimic the monocyte adherence to endothelial cells, we used a flow chamber system to assess progestogen effects on U937 monocytoid cell adherence to HUVEC monolayers. We also examined the suppression effects of adhesion molecules with small interference RNAs. RESULTS: mRNA levels of adhesion molecules in HUVECs treated with medroxyprogesterone acetate (MPA) or 17ß-estradiol + MPA were 1.7- to 2.5-fold higher than those in the control. MPA increased the protein expression of E-selectin, P-selectin, and intercellular adhesion molecule-1 compared with that for the control (83.0 ± 0.7, 34.8 ± 1.2, and 5.4 ± 0.0 ng/mL, respectively), whereas other progestogens or 17ß-estradiol additive to progestogens did not significantly change expression. MPA significantly increased U937 monocytoid cell adherence compared with the control (56.0 ± 1.5 vs 46.5 ± 3.5 adherent cells per 10 fields) but did not increase adherence to HUVECs with knocked down intercellular adhesion molecule-1. CONCLUSIONS: MPA increases cell adhesion molecule expression on HUVECs, causing increased numbers of monocytoid cells to adhere to HUVECs. These MPA effects may be a risk factor for atherogenesis on endothelial cells in postmenopausal women receiving hormone replacement therapy.

Usefulness of moistening seprafilm before use in laparoscopic surgery.

PURPOSE: Seprafilm is an ideal synthetic adhesion barrier, but its insertion into the abdomen in laparoscopic surgery is difficult because of its stiff and brittle nature. We tested the usefulness of a novel technique of moistening Seprafilm before use to increase its flexibility before insertion through a trocar during laparoscopic surgery. METHODS: Laparoscopic pelvic surgeries that were followed by insertion of Seprafilm were evaluated in 67 women. A piece of Seprafilm (1/6 or 1/4 the size of a full sheet) was placed on gauze moistened with saline solution to soften it. The prepared piece was then rolled, inserted with forceps through a 12-mm trocar port, and placed at the intended site. RESULTS: A total of 245 pieces of Seprafilm sheets were pretreated and inserted using a 12-mm trocar port with a success rate of 100% and placed correctly with a success rate of 80.0% (196 of the 245 pieces). The mean total time required for placement of all pieces per surgery was 601±248 seconds. CONCLUSIONS: This is a simple and effective technique that enables the film to be applied securely without breaking and without the need for special equipment.

Distinct acoustic features in spinal and bulbar muscular atrophy patients with laryngospasm.

OBJECTIVE: Laryngospasm is a sudden onset of transient respiratory difficulty that is perceived as life-threatening by patients with spinal and bulbar muscular atrophy (SBMA). The purpose of the study was to analyze the voice characteristics of SBMA patients with laryngospasm using acoustic voice analysis. METHODS: Acoustic measurements were obtained from 39 consecutive Japanese patients with genetically confirmed SBMA. A comparison was made between the acoustic voice profiles of 16 patients with laryngospasm and 23 patients without laryngospasm within 6 months before the evaluation. Computerized acoustic analysis was performed for a prolonged vowel (/a:/) using the Multi-Dimensional Voice Program (MDVP). RESULTS: SBMA patients with laryngospasm had smaller fluctuations of vocal fold vibration and the turbulent noise component, indicating stronger vocal fold closure than in those without laryngospasm. Receiver operating characteristic curve analysis showed that the noise-to-harmonic ratio, which globally measures the noise components of voice, is the most useful acoustic parameter to distinguish laryngospasm (area under the curve = 0.767, p = 0.007). CONCLUSIONS: The smaller noise component in patients with laryngospasm suggests that the vocal folds of these patients are more adducted during phonation than those of the patients without laryngospasm, even in the absence of laryngospasm. Quantitative laryngeal analysis using the MDVP helps to detect laryngeal dysfunction and provides physiological insight into the pathophysiology of laryngospasm in SBMA.

Behavior management approach for agitated behavior in Japanese patients with dementia: a pilot study.

BACKGROUND: Agitated behaviors are frequently observed in patients with dementia and can cause severe distress to caregivers. However, little evidence of the efficacy of nonpharmacological interventions for agitated behaviors exists for patients with dementia. The present pilot study aimed to evaluate a behavioral management program developed by the Seattle Protocols for patients with agitated behaviors in Japan. METHODS: Eighteen patients with dementia (Alzheimer's disease, n = 14; dementia with Lewy bodies, n = 4) participated in an open study testing the effectiveness of a behavioral management program. The intervention consisted of 20 sessions over the course of 3 months. The primary outcomes were severity of agitation in dementia, as measured using the Agitated Behavior in Dementia scale (ABID) and the Cohen-Mansfield Agitation Inventory (CMAI). RESULTS: The behavioral management program resulted in significant reductions in total scores on both the ABID and CMAI. Although both physically agitated and verbally agitated behavior scores on the ABID improved significantly, symptoms of psychosis did not improve after the intervention. CONCLUSION: The behavioral management technique may be beneficial to distressed caregivers of patients with dementia. In the future, a well designed study to develop the behavioral management program more fully is needed.

Estrogen-related receptor-γ regulates estrogen receptor-α responsiveness in uterine endometrial cancer.

OBJECTIVE: Estrogen-related receptors (ERRs) are orphan nuclear receptors that modulate the estrogen receptor (ER)-mediated pathway and play roles in the regulation of breast and prostate cancer cell growth. However, the significance of the localization and the function of ERRs in uterine endometrial cancer remain unclear. We aimed to measure the expression of ERRγ and determine its association with the ER-mediated pathway in human endometrial cancer. METHODS: Proliferation, luciferase, and quantitative polymerase chain reaction assays were performed in ERα-positive (Ishikawa) and ERα-negative (HEC1A) endometrial cancer cell lines. The association between ERRγ and ERα expressions was determined by immunohistochemical analysis in uterine endometrial cancer tissues. RESULTS: Estrogen-induced estrogen response element transcriptional activity was repressed by ERRγ in ERα-positive cells but was stimulated by ERRγ in ERα-negative cells. The stable overexpression of ERRγ regulated the in vitro cell growth in the ERα-positive and ERα-negative endometrial cancer cell lines. A selective ERRγ agonist, DY131, inhibited the growth of the ERα-positive endometrial cancer cells but promoted that of the ERα-negative cancer cells. Furthermore, we found that ERRγ is expressed in the nuclei of human uterine endometrial cancer tissues. Estrogen-related receptor γ was not associated with pathological parameters such as the International Federation of Gynecology and Obstetrics stage and histological type. The uterine endometrial cancer tissues with ERRγ-positive/ERα-negative status may have a significantly poor prognosis. CONCLUSIONS: The relationship between ERRγ and ERα status could be a predictive marker for the treatment of uterine endometrial cancer, which provides an impetus for the identification of ligands for nuclear orphan receptor ERRγ.

Reliability and validity of the Japanese version of the Agitated Behaviour in Dementia Scale in Alzheimer's disease: three dimensions of agitated behaviour in dementia.

BACKGROUND: Agitation in dementia seriously affects not only patients' quality of life (QOL), but also caregivers' QOL. Thus, an appropriate assessment of agitated behaviour in dementia is needed for clinical management. We developed the Japanese version of the Agitated Behaviour in Dementia scale (ABID), examined its reliability and validity, and carried out its factor analysis to elucidate its factor structure. METHODS: The Japanese version of the ABID was given caregivers of 149 Japanese patients with Alzheimer's disease (AD). The internal-consistency, test-retest reliability and concurrent validity of the Japanese version of the ABID were then examined. A factor analysis was used to examine the agitated behavioural dimensions underlying ABID. RESULTS: The Japanese version of the ABID showed an excellent internal reliability for both frequency ratings (Cronbach's α= 0.89) and reaction ratings (Cronbach's α= 0.92), and an excellent test-retest reliability for both frequency ratings and reaction ratings. The total score for the frequency ratings of the ABID was significantly associated with the Cohen-Mansfield Agitation Inventory (CMAI), and the total score for the reaction ratings of the ABID was significantly associated with the Zarit Burden Interview. The factor analysis showed three subtypes: physically agitated behaviour, verbally agitated behaviour and psychosis symptoms. CONCLUSIONS: The Japanese version of the ABID promises to be useful for assessing agitated behaviour in patients with AD. Importantly, understanding these subtypes of agitated behaviour might have implications for individualized treatment plans.

Estrogen-related receptor α expression and function are associated with vascular endothelial growth factor in human cervical cancer.

INTRODUCTION: Estrogen-related receptor α (ERRα), one of orphan nuclear receptors with an unknown ligand, is expressed in various types of cancer. Increased ERRα levels are associated with a higher risk of recurrence and poor clinical outcome in breast cancer, suggesting that ERRα could be a negative prognostic factor. Recently, it has been suggested that vascular endothelial growth factor (VEGF) could be one of the transcriptional targets of ERRα in breast cancer. Here, we examined the expression of ERRα and the association of ERRα with VEGF in uterine cervical cancer cells and tissues. METHODS: We evaluated the expression of ERRα and VEGF by immunohistologic analysis using specimens from 40 patients with invasive cervical cancer. We also evaluated the VEGF promoter activity of ERRα in cervical cancer cell lines by transfection and luciferase assay. We overexpressed or knocked down ERRα and examined VEGF expression by real-time polymerase chain reaction. Finally, cell proliferation assay was performed to examine whether ERRα affects tumor growth in cervical cancer. RESULTS: Immunohistologic analysis demonstrated that ERRα expression in cervical cancer tissues was higher than that in noncancerous tissues and that there was a positive association between ERRα and VEGF expression in cancer tissues (P < 0.05). We showed that ERRα stimulated the VEGF promoter activity in cervical cancer cell lines. We further showed the overexpression and knockdown of ERRα-regulated VEGF expression level by real-time polymerase chain reaction. Moreover, we showed that ERRα and VEGF knockdown by small interfering RNA or an inverse agonist of ERRα, XCT 790, could suppress cell growth compared with control cells in cervical cancer. CONCLUSIONS: We have provided compelling evidence that ERRα affects VEGF expression and tumor growth in cervical cancer. These results justify further investigation into the use of ERRα as a therapeutic target for patients with uterine cervical cancer.

Distinct neuropsychological profiles of three major symptom dimensions in obsessive-compulsive disorder.

Recent neuroimaging studies have suggested that different symptom dimensions are mediated by partially distinct neural systems in obsessive-compulsive disorder (OCD). However, the correlations between neuropsychological profiles and symptom dimensions in OCD are unknown. The aim of this study was to examine the extent to which OCD symptom dimensions were associated with episodic memory and attention and executive functions. The symptom dimensions of 63 patients with OCD were assessed using both the Padua Inventory and the Y-BOCS symptom checklist. Then, we administered the Logical Memory (LM) subset of the Wechsler Memory Scale-Revised (WMR-R) test and evaluated inhibition (Stroop test, Trail Making test) and cognitive flexibility (Digit Symbol test, Letter Fluency, and Category Fluency). While associations were observed between scores on the contamination/cleaning dimension and better performances on the LM and Trail Making tests, associations were also observed between scores on the aggressive/checking dimension and poorer performances on the Trail Making test. In addition, we found that scores on the symmetry/ordering dimension were associated with poorer performances on the LM and Trail Making tests. Our results support the hypothesis that different symptoms may represent distinct and partially overlapping neurocognitive networks in OCD patients.
