RESUMO

BACKGROUND: Ultrasound-guided percutaneous cryoablation (PCA) for early-stage breast cancer (ESBC) can be performed under local anesthesia in an outpatient clinic. This study continues a pilot stage to examine local control, safety, patient quality of life (QoL), satisfaction and cosmetic outcomes of cryoablation for ESBC. METHODS: PCA was performed under local anesthesia for patients with primary ESBC, followed by radiation and endocrine therapies. Oncologic outcomes were examined by imaging (mammography, ultrasound, MRI) at baseline and 1, 6, 12, 24, 36, and 60 months post-cryoablation. EQ-VAS, EQ-5D-5L, subjective satisfaction and Moiré topography were used to measure health-related QoL outcomes. RESULTS: Eighteen patients, mean aged 59.0 ± 9.0 years, mean tumor size 9.8 ± 2.3 mm, ER + , PR + (17/18), HER2-, Ki67 < 20% (15/18), underwent PCA and were followed for a mean of 44.3 months. No serious adverse events were reported, and no patients had local recurrence or distant metastasis in the 5-year follow-up. Cosmetic outcomes, satisfaction level, and QoL all improved post-cryoablation. Five-year average reduction rates of the cryolesion long, short, and depth diameters, on US, were 61.3%, 42.3%, and 22.8%, respectively, compared to the 86.2% volume reduction rate on MRI. The correlation coefficient between MRI and US measurement criteria was highest for the long diameter. During follow-up, calcification of the treated area was observed in 13/18 cases. CONCLUSION: Cryoablation for ESBC is an effective and safe procedure with excellent cosmetic outcomes and improved QoL. This study contributes to the growing evidence supporting cryoablation as a potential standard treatment for ESBC, given compliance to pre-defined patient selection criteria.

RESUMO

This study aimed to determine whether the distance of gait training using a hybrid assistive limb (HAL) is related to the improvement of walking independence in patients with acute brain injury. This was an exploratory, observational study. Thirty patients having hemiplegia (functional ambulation category, FAC score ≤2) with acute stroke or after brain tumor surgery were included. Patients performed 4 sessions of gait training using HAL (60 min/session), 1-3 sessions/week, combined with conventional physical therapy. The gait distance achieved in the four training sessions using HAL was measured. FAC score was measured before and after intervention. Patients were divided into groups A, B, and C, for FAC score improvements of 0, 1, and ≥2, respectively. Gait distance was compared among groups using one-way analysis of variance. Gait distance in group C was significantly longer than that ingroup A [mean (standard deviation): 2527 (1725) m vs. 608 (542) m]. This study suggested that the gait distance achieved during training using the HAL may be a clinical indicator of the effectiveness of the HAL on gait training in patients with acute brain injury.Clinical trial registration number: UMIN000012764 R000014756.

RESUMO

Lithium's inhibitory effect on enzymes involved in sulfation process, such as inhibition of 3'(2')-phosphoadenosine 5'-phosphate (PAP) phosphatase, is a possible mechanism of its therapeutic effect for bipolar disorder (BD). 3'-Phosphoadenosine 5'-phosphosulfate (PAPS) is translocated from cytosol to Golgi lumen by PAPS transporter 1 (PAPST1/SLC35B2), where it acts as a sulfa donor. Since SLC35B2 was previously recognized as a molecule that facilitates the release of D-serine, a co-agonist of N-methyl-D-aspartate type glutamate receptor, altered function of SLC35B2 might be associated with the pathophysiology of BD and schizophrenia (SCZ). We performed genetic association analyses of the SLC35B2 gene using Japanese cohorts with 366 BD cases and 370 controls and 2012 SCZ cases and 2170 controls. We then investigated expression of SLC35B2 mRNA in postmortem brains by QPCR using a Caucasian cohort with 33 BD and 34 SCZ cases and 34 controls and by in situ hybridization using a Caucasian cohort with 37 SCZ and 29 controls. We found significant associations between three SNPs (rs575034, rs1875324, and rs3832441) and BD, and significantly reduced SLC35B2 mRNA expression in postmortem dorsolateral prefrontal cortex (DLPFC) of BD. Moreover, we observed normalized SLC35B2 mRNA expression in BD subgroups who were medicated with lithium. While there was a significant association of SLC35B2 with SCZ (SNP rs2233437), its expression was not changed in SCZ. These findings indicate that SLC35B2 might be differentially involved in the pathophysiology of BD and SCZ by influencing the sulfation process and/or glutamate system in the central nervous system.

RESUMO

D-Serine has been shown to play an important role in the expression and control of a variety of brain functions by acting as the endogenous coagonist for the N-methyl-D-aspartate type glutamate receptor (NMDAR), at least, in the forebrain. To obtain further insight into the still debatable cellular localization of the D-amino acid, we have examined the effects of the selective destruction of the neuronal cell bodies by quinolinate on the tissue or extracellular D-serine concentrations in the medial prefrontal cortex of the rat. A local quinolinate infusion into the bilateral medial prefrontal cortex produced a cortical lesion with a marked (- 65%) and non-significant alteration (- 5%) in the cortical and striatal tissue D-serine concentrations, respectively, 7 days post-infusion. In vivo microdialysis experiments in the right prefrontal lesion site 9 days after the quinolinate application revealed that the basal extracellular D-serine levels were also dramatically reduced (- 64%). A prominent reduction in the tissue levels of GABA in the interneurons of the prefrontal cortex (- 78%) without significant changes in those in the striatum (+ 12%) verified that a major lesion part was confined to the cortical portion. The lack of a significant influence of the prefrontal quinolinate lesion on its dopamine concentrations in the mesocortical dopamine projections suggests that the nerve terminals and axons in the lesion site may be spared. These findings are consistent with the perikarya-selective nature of the present quinolinate-induced lesion and further support the view that neuronal cell bodies of intrinsic neurons in the prefrontal cortical region contain substantial amounts of D-serine, which may sustain the basal extracellular concentrations of D-serine.

RESUMO

ABSTRACT: The purpose of this study is to investigate the predictive factors of home discharge for rehabilitation patients with cancer bone metastasis.Cancer patients with bone metastasis who underwent rehabilitation between April 2014 and March 2017 were retrospectively enrolled. Data on discharge destination were collected from medical records as outcomes. Multiple regression analyses were carried out to investigate the predictive factors of home discharge.Ninety-eight patients (mean age: 68.6 years, 42 females and 56 males) were included. Fifty patients were discharged home, 38 patients were discharged to other facilities, and 10 patients died. There were no skeletal-related events among these patients during their hospital stay. The receiver-operating curve for the predictive factors for home discharge of the Barthel Index at admission, Eastern Cooperative Oncology Group Performance Status at admission, and number of immediate family members living at home were 60 points (area under the curve [AUC] = 0.74, sensitivity = 0.6400, 1-specificity = 0.2766), 2 score (AUC = 0.65, sensitivity = 0.5400, 1-specificity = 0.2222), and 1 family member (AUC = 0.65, sensitivity = 0.9592, 1-specificity = 0.7222), respectively.In order to plan for cancer patients with bone metastasis to be discharged home, it is important to take into consideration the patients' Barthel Index and Performance Status at the time of hospital admission and the number of immediate family members living at home.

RESUMO

Using a robot for gait training in stroke patients has attracted attention for the last several decades. Previous studies reported positive effects of robot rehabilitation on gait function in the short term. However, the long-term effects of robot rehabilitation for stroke patients are still unclear. The purpose of the present study was to investigate the long-term effects of periodic gait training using the Hybrid Assistive Limb (HAL) on gait function in chronic stroke patients. Seven chronic stroke patients performed 8 gait training sessions using the HAL 3 times every few months. The maximal 10-m walk test and the 2-minute walking distance (2MWD) were measured before the first intervention and after the first, second, and third interventions. Gait speed, stride length, and cadence were calculated from the 10-m walk test. Repeated one-way analysis of variance showed a significant main effect on evaluation time of gait speed (F = 7.69, p < 0.01), 2MWD (F = 7.52, p < 0.01), stride length (F = 5.24, p < 0.01), and cadence (F = 8.43, p < 0.01). The effect sizes after the first, second, and third interventions compared to pre-intervention in gait speed (d = 0.39, 0.52, and 0.59) and 2MWD (d = 0.35, 0.46, and 0.57) showed a gradual improvement of gait function at every intervention. The results of the present study showed that gait function of chronic stroke patients improved over a year with periodic gait training using the HAL every few months.

RESUMO

Excessive accumulation of amyloid ß-protein (Aß) is one of the primary mechanisms that leads to neuronal death with phosphorylated tau in the pathogenesis of Alzheimer's disease (AD). Protofibrils, one of the high-molecular-weight Aß oligomers (HMW-Aßo), are implicated to be important targets of disease modifying therapy of AD. We previously reported that phenolic compounds such as myricetin inhibit Aß1-40, Aß1-42, and α-synuclein aggregations, including their oligomerizations, which may exert protective effects against AD and Parkinson's disease. The purpose of this study was to clarify the detailed mechanism of the protective effect of myricetin against the neurotoxicity of HMW-Aßo in SH-SY5Y cells. To assess the effect of myricetin on HMW-Aßo-induced oxidative stress, we systematically examined the level of membrane oxidative damage by measuring cell membrane lipid peroxidation, membrane fluidity, and cell membrane potential, and the mitochondrial oxidative damage was evaluated by mitochondrial permeability transition (MPT), mitochondrial reactive oxygen species (ROS), and manganese-superoxide dismutase (Mn-SOD), and adenosine triphosphate (ATP) assay in SH-SY5Y cells. Myricetin has been found to increased cell viability by suppression of HMW-Aßo-induced membrane disruption in SH-SY5Y cells, as shown in reducing membrane phospholipid peroxidation and increasing membrane fluidity and membrane resistance. Myricetin has also been found to suppress HMW-Aßo-induced mitochondria dysfunction, as demonstrated in decreasing MPT, Mn-SOD, and ATP generation, raising mitochondrial membrane potential, and increasing mitochondrial-ROS generation. These results suggest that myricetin preventing HMW-Aßo-induced neurotoxicity through multiple antioxidant functions may be developed as a disease-modifying agent against AD.

RESUMO

16p11.2 deletion is one of the most influential copy number variations (CNVs) associated with autism spectrum disorder (ASD). Previous studies have investigated the pathophysiology of 16p11.2 deletion both in vitro and in vivo, and have identified features such as NMDAR dysfunction, excitation-inhibition imbalance, transcriptional dysregulation, and impaired cortical development. However, little is known about the transcriptional profiles of human neural cells. Here, we constructed an isogenic human embryonic stem (hES) cell model with 16p11.2 deletion using a CRISPR/Cas9 system and performed transcriptome analyses of hES-derived 2-dimensional neural cells. We identified several characteristics which may correlate with the neuropathology of 16p11.2 deletion: predisposition to differentiate into neural lineages, enhanced neurogenesis, and dysregulation of G protein-coupled receptor signaling and RAF/MAPK pathway. We also found upregulation of fragile X mental retardation protein (FMRP) target genes including GRM5, which is implicated as a common trait between 16p11.2 deletion and fragile X syndrome. Extending our knowledge into other ASD models would help us to understand the molecular pathology of this disorder.

RESUMO

AIMS/INTRODUCTION: The association between diabetes and periodontal disease is considered to be bidirectional. However, there is still controversy surrounding the relationship between periodontal disease and type 1 diabetes. We investigated whether insulin improves periodontitis without any local treatments for periodontitis under type 1 diabetes conditions using the ligature-induced experimental periodontitis model. MATERIALS AND METHODS: Type 1 diabetic rats were induced by streptozotocin injection. Experimental periodontitis was induced by ligature in normal and diabetic rats. Half of the diabetic rats were treated with insulin. Two weeks after the ligature, periodontitis was evaluated. RESULTS: Insulin treatment significantly improved inflammatory cell infiltration and inflammatory cytokine gene expression, leading to suppression of alveolar bone loss, in the periodontitis of diabetic rats. Insulin also suppressed the periodontitis-increased nitric oxide synthase-positive cells in periodontal tissue of the diabetic rats. Even without induction of periodontitis, diabetic rats showed decreased gingival blood flow and an increased number of nitric oxide synthase-positive cells in the gingiva and alveolar bone loss compared with normal rats, all of which were ameliorated by insulin treatment. We further confirmed that insulin directly suppressed lipopolysaccharide-induced inflammatory cytokine expressions in THP-1 cells. CONCLUSIONS: There were abnormalities of periodontal tissue even without the induction of periodontitis in streptozotocin-induced diabetic rats. Insulin treatment significantly ameliorated periodontitis without local periodontitis treatment in diabetic rats. These data suggest the therapeutic impacts of insulin on periodontitis in type 1 diabetes.

RESUMO

We report a case of right uretero-external iliac artery fistula. A 46-year-old woman diagnosed with left ovarian cancer with peritoneal dissemination underwent simple hysterectomy, bilateral adnexal removal, partial omentectomy and appendectomy. Sixteen months after the operation, a computed tomography scan showed right hydronephrosis due to the development of tumor within the pelvis. A ureteral stent was placed into the right ureter in order to preserve renal function. The ureteral stent was replaced at regular intervals. Five months after the ureteral stent placement, the patient was hospitalized urgently with gross hematuria. She was diagnosed with right uretero-external iliac artery fistula based on the angiographic examination that was conducted to detect the source of hemorrhage. She was treated successfully with endovascular stent grafting in the right external iliac artery. She has since shown no episode of hematuria.

RESUMO

Objectives: Recently, use of the Hybrid Assistive Limb (HAL) that is effective for improvement of gait ability in chronic stroke patients has been reported. However, how long the effects are maintained remains unknown. The purpose of the present study was to investigate whether the effect of gait training using the HAL on gait ability was maintained for 3 months after the intervention. Methods: A longitudinal, observational study with an intervention for a single group that adhered to the STROBE guidelines was performed. Nine chronic stroke patients were enrolled in this study. The patients performed gait training sessions using the HAL, 2-5 sessions/week for 3 weeks. Gait speed, stride length, cadence, and 2-minute walk distance (2MWD) were measured before and after intervention and at 3-month follow-up. The clinical trial registration number of this study is UMIN000012764 R000014756. Results: Compared to the initial status, gait speed (p = .02), stride length (p = .03), cadence (p = .01), and 2MWD (p < .05) were significantly increased immediately after the intervention. Moreover, gait speed (p < .01), cadence (p = .03), and 2MWD (p = .02) remained significantly higher 3 months after the intervention. There were no significant changes in all outcome measures between after intervention and at 3-month follow-up. Conclusions: This study showed that gait training using the HAL resulted in significant improvement of gait ability after the intervention and the effect was maintained for 3 months after the training.

RESUMO

Oral dysesthesia denotes a condition characterized by abnormal sensations in oral regions without a somatic basis, and is often seen in people with autistic traits, including those with autism spectrum disorder. This study aimed to examine the association between the symptoms of oral dysesthesia and the degree of autistic traits. A retrospective chart review was performed on 44 patients with oral dysesthesia, and associations among the subscales of the Oral Dysesthesia Rating Scale (Oral DRS), Autism Spectrum Quotient (AQ), and Glasgow Sensory Questionnaire (GSQ) were investigated. A Pearson correlation analysis revealed a significant, positive correlation between AQ scores and the A3 (squeezing or pulling) subscale of the Oral DRS (r = 0.37), but there were no significant correlations between the AQ and other subscale scores. There was a significant correlation between the AQ and GSQ score, but no correlation was detected between the GSQ and A3 scores or any other Oral DRS subscale scores. In conclusion, an abnormal squeezing or pulling sensation in oral regions without a somatic basis was associated with autistic traits and could be highlighted as a specific abnormality in sensory processing in autism spectrum disorder.

RESUMO

BACKGROUND: Robotic rehabilitation has been attracting attention as a means to carry out "intensive", "repetitive", "task-specific", gait training. The newly developed robotic device, the Hybrid Assistive Limb (HAL), is thought to have the possibility of having an excellent effect on gait speed improvement over the conventional automatic programed assist robot. The purpose of this study was to investigate the spatiotemporal characteristics related to gait speed improvement using the HAL in chronic stroke patients. RESEARCH QUESTION: To investigate the effects of robotic gait training on gait speed and gait parameters. METHODS: An observational study with an intervention for single group was used. Intervention was conducted in University Hospital. Eleven chronic stroke patients were enrolled in this study. The patients performed 8 gait training sessions using the HAL, 2-5 sessions/week for 3 weeks. Gait speed, stride length, cadence, time of gait cycle (double-limb stance phases and single-limb stance phases) and time asymmetry index were measured before and after intervention. RESULTS: After intervention, gait speed, stride length, and cadence were significantly improved (Effect size = 0.39, 0.29, and 0.29), the affected initial double-limb stance phase was significantly shortened (from 15.8 ± 3.46%-13.3 ± 4.20%, p = .01), and the affected single-limb stance phase was significantly lengthened (from 21.8±7.02%-24.5±7.95%, p < .01). The time asymmetry index showed a tendency to improve after intervention (from 22.9±11.8-17.6±9.62, p = .06). There was a significant correlation between gait speed and the stride length increase rate (r = .72, p = .01). SIGNIFICANCE: This study showed that increasing stride length with lengthening of the affected single-stance phase by gait training using the HAL improved gait speed in chronic stroke patients. However, the actual contributions on HAL cannot be separated from gait training because this study is an observational research without a control group.

RESUMO

Objectives: The siderophore cephalosporin cefiderocol possesses in vitro activity against MDR Gram-negative bacteria. The stability of cefiderocol against serine- and metallo-type carbapenemases has been reported previously, but little is known about how cefiderocol interacts with chromosomal AmpC ß-lactamases. We investigated a number of features of cefiderocol, namely antibacterial activity against AmpC overproducers, stability against AmpC ß-lactamases and propensity for AmpC induction using Pseudomonas aeruginosa and Enterobacter cloacae. Methods: MICs were determined by broth microdilution according to CLSI guidelines. The MIC of cefiderocol was determined in iron-depleted CAMHB. Hydrolysis of the antibiotics was determined by monitoring the changes in the absorbance in the presence of AmpC ß-lactamase, and AmpC induction was evaluated by double disc diffusion and nitrocefin degradation assays. Results: The MICs of ceftazidime and cefepime for PAO1 increased 4- to 16-fold with inactivation of either ampD or dacB, whereas cefiderocol MICs were little affected by these inactivations (<2-fold increase). Cefiderocol has 17- and 740-fold lower affinity (higher Ki) to AmpCs of P. aeruginosa SR24-12 and E. cloacae P99, respectively, compared with ceftazidime. Both disc diffusion and nitrocefin degradation assays indicated that cefiderocol did not induce AmpC ß-lactamases of P. aeruginosa PAO1 and ATCC 27853 and E. cloacae ATCC 13047, whereas imipenem did. Conclusions: Cefiderocol showed in vitro activity against the AmpC-overproducing strains, low affinity for chromosomal AmpC ß-lactamases, and a low propensity of temporal induction of AmpC ß-lactamases of P. aeruginosa and E. cloacae. These features relating to chromosomal AmpC could explain the potent antibacterial activity of cefiderocol against drug-resistant strains producing AmpC ß-lactamases.

RESUMO

OBJECTIVE: Oral cenesthopathy is characterized by foreign body sensations without medical and dental evidence for them. It is thought to be a rare disease in psychiatry, but many patients are visiting dental clinics seeking treatment to remove a foreign body. Even though the features of oral cenesthopathy might be different between a psychiatric clinic and a dental clinic, there has been no clinic-statistical study from dentists. In this study, we report a clinico-statistical study of patients with oral cenesthopathy in dentistry. METHODS: This is a retrospective chart review of 606 outpatients with oral cenesthopathy in Tokyo Medical and Dental University from April 2010 through to March 2015. RESULTS: A total of 159 male and 447 female patients were included in this study. The mean age was 62.08 years, and female patients were older than male patients. The trigger of the dental treatment and the acute phase of depression at the onset were significantly related (p=0.037). Only 128 patients (36%) had clinically significant improvement after 6 months of pharmacotherapy. No history of psychiatric disorders (odds ratio [OR] 0.479 [95% confidence interval {CI}: 0.262-0.875], p=0.017) and longer duration of illness (>18 months) (OR 2.626 [95% CI: 1.437-4.799], p=0.002) were significant factors for clinical outcomes. CONCLUSION: Patients with oral cenesthopathy in our clinic were predominantly elderly female patients. Dental treatment in the acute phase of depression might be a risk factor for oral cenesthopathy. Therefore, comprehending the situation of psychiatric disorder and obtaining adequate informed consent might be required to prevent the trouble concerning oral cenesthopathy.

RESUMO

Transurethral resection of bladder tumor (TURBT) was performed on the bladder tumor of a 68-yearold male patient. Bacillus Calmette-Guérin (BCG) intravesical therapy was performed to prevent recurrence (Immunobladder : ○R 80 mg once/week×6 times). A 40 mm tumor was noted in the left kidney by renal ultrasound performed two months after the completion of BCGintravesical therapy. Computed tomography (CT) showed non-enhanced multiple mass lesions in the left kidney. Renal tuberculous granuloma, hypovascular renal cell carcinoma or malignant lymphoma was suspected and CT-guided needle biopsy was performed. The patient was diagnosed with renal tuberculous granuloma that developed after BCGintravesical therapy as epithelioid cell granulomas were noted in the biopsy results. Treatment with anti-tuberculosis drugs was started and the tumor showed signs of shrinkage.

The structure-activity relationship (SAR) for a novel series of catechol conjugated siderophore cephalosporins is described with their in vitro activities against multi-drug resistant Gram-negative pathogens including Pseudomonas aeruginosa, Acinetobacter baumannii, Stenotrophomonas maltophilia and Enterobacteriaceae. Cefiderocol (3) was one of the best molecules which displayed well-balanced and potent activities against multi-drug resistant Gram-negative pathogens including carbapenem resistant bacteria among the prepared compounds with the modified C-7 side chain and the modified C-3 side chain. Cefiderocol (3) is a highly promising parenteral cephalosporin for the treatment of multi-drug resistant Gram-negative infection.

RESUMO

OBJECTIVES: Contrast-enhanced ultrasonography can evaluate microcirculation. Thus, we used contrast-enhanced ultrasonography in evaluating pancreas graft perfusion and examined the relationship between graft circulation and function. METHODS: Contrast-enhanced ultrasonography was performed in 17 cases within 24 hours and at 1, 3, 5, 7, 14, 21, and 28 days after transplantation (Tx). The time between the time to peak intensity in the parenchyma and that in the vein was defined as delta-Tp(P-V). Graft function was evaluated with oral glucose tolerance test (OGTT) at 1 and 3 months after Tx, and glucagon stimulation test at 1 month after Tx. RESULTS: Differences in delta-Tp(P-V) between individual cases were more significant early after Tx, and delta-Tp(P-V) within 24 hours (delta-Tp[P-V]24h) was used in the subsequent analysis. Delta-Tp(P-V)24 hours showed a negative correlation with C-peptide increment in the glucagon stimulation test and the area under the curve of insulin level in oral glucose tolerance test. The cases were divided into the following 2 groups: the standard group (delta-Tp[P-V]24h ≤6.10 seconds) and the delayed group (>6.10 seconds). The area under the curve of insulin level increased significantly from 1 to 3 months after Tx in the standard group only. CONCLUSIONS: These results suggest that delta-Tp(P-V)24 hours affects insulin secretion after Tx. Contrast-enhanced ultrasonography is useful in predicting endocrine function of the graft.
