Published: December 2019

Various clinical tests are used to evaluate the palmaris longus tendon, but their accuracy is unknown. We assessed the accuracy of clinical tests (Schaeffer’s, Thompson’s, Mishra-I, Mishra-II) against ultrasound as the reference standard. We hypothesized that Schaeffer’s was most accurate and that examination can reliably assess the palmaris longus tendon’s length. Ninety-six wrists were examined clinically and evaluated with ultrasound by radiologists who were blinded to examination results. We calculated diagnostic accuracy and agreement between length measurements. Sensitivity values were as follows: Schaeffer’s 94%, Mishra-I 100%, Mishra-II 100%, Thompson’s 72%. Specificity values were as follows: Schaeffer’s 94%, Mishra-I 83%, Mishra-II 89%, Thompson’s 91%. Intraclass correlation coefficient between palmaris longus tendon length measurement on examination and ultrasound was 0.54. Schaeffer’s test accurately detected this tendon with >90% sensitivity and specificity, but clinical examination less reliably measured palmaris longus tendon length. Ultrasound may be a useful adjunct to assess potential graft length preoperatively. Level of evidence: I
Appreciation for food, an important concept in mindful eating: association with home and school education, attitude, behavior, and health status in Japanese elementary school children
Authors: Kawasaki Yui , Akamatsu Rie 
Published: December 2019

Background: Appreciating food is an important concept in mindful eating, mentioned by advocates of an expanded model of mindful eating in 2016. With the exception of Japan, this concept is not common in many countries. Objective: We aimed to describe the role that appreciation for food has in the health of children from two perspectives: 1) association between children’s appreciation for food and their backgrounds, such as home and school educational experiences related to food, and 2) association between their appreciation for food and outcomes, such as attitude toward food, eating behaviors, and health status. Design: Cross-sectional. Methods: Data were obtained from self-administered anonymous questionnaires sent to 2070 elementary school students in Tokyo, Japan, during October and December 2006. They contained several question items pertaining to the characteristics of participants: home and school educational experiences related to food, attitudes towards food (including level of appreciation for food), eating behaviors, and health status. T-test, Pearson’s correlation coefficient, and simple and multiple linear regression analyses were used to compare the total score of appreciation for food with other factors. Results: Surveys were completed by 1994 children (response rate: 96.3%) and significant correlations were indicated by gender, educational experiences at home and school, attitudes toward healthy food, recommended food preferences, breakfast consumption, and body mass index. Conclusions: We concluded that appreciation for food plays an important role in children’s health.

Purpose: Synchronous endometrial and ovarian cancer is defined as the concurrent presence of ovarian cancer with endometrial cancer. We aimed to evaluate whether there is an effect of endometriosis on progression-free survival and overall survival of women with synchronous endometrial and ovarian cancer. We also compared these findings with the patients having endometrial-only tumors and ovarian-only tumors. Methods: The patients who underwent surgery for endometrioid or clear-cell endometrial-only tumors and/or ovarian-only tumors and synchronous endometrial and ovarian cancer between 2005 and 2016 were included in this cohort study. The effect of the presence of endometriosis on progression-free survival and overall survival in these women who met the criteria was determined using statistical methods. Women were also compared regarding their demographic, clinical, and pathological characteristics. Results: A total of 176 patients were included in this study. All histology types of tumors located in endometrium or ovary were endometrioid or clear-cell cancer. Endometriosis was present in 62 patients (35.2%), whereas adenomyosis was present in 44 patients (25%). Endometriosis was diagnosed more frequently in women with ovarian-only tumors and synchronous endometrial and ovarian cancer than those with endometrial-only tumors (59.2% vs 5.7%, p < 0.001 and 45.7% vs 5.7%, p < 0.001, respectively). The patients with endometriosis showed no significantly longer progression-free survival and overall survival (hazard ratio = 1.70; 95% confidence interval = 0.48–6.03; p = 0.408 and hazard ratio = 1.67; 95% confidence interval = 0.30–9.44; p = 0.562, respectively). The presence of endometriosis was a stronger predictor for progression-free survival and overall survival comparing with the presence of adenomyosis. Conclusion: The women with synchronous endometrial and ovarian cancer should be informed that endometriosis has no detrimental effect on progression-free survival and overall survival.

Published: December 2019

Background and aims Children’s early interactions with books are important for fostering development of oral language and emergent literacy skills. It is not known whether children diagnosed with autism spectrum disorder show different preferences for text types in the home environment prior to school entry. The current study aimed to: (i) investigate parent-reports of the favourite books of their children with autism spectrum disorder compared to typically developing children and (ii) identify whether there are differences in the reasons why books were preferred across the two groups. Methods Participants included children (aged 26–70 months) with autism spectrum disorder ( n =  41) and typically developing peers ( n =  164). Parent-reports of their child’s current favourite book/s were coded as fiction versus non-fiction and also category type. Parents also reported why the book was considered a favourite and this was coded. Results There were no differences between groups for fiction versus non-fiction, with both groups preferring fiction (>95% of responses). A strong category preference for animal topics across both groups was present. Significant group differences were found when asked to select specific reasons for favourite book preferences. Conclusions This study provides preliminary evidence of similarities between preschool children with autism spectrum disorder and typically developing peers’ preferences for fiction books during the early years. Implications It should not be assumed that children with autism spectrum disorder have different preferences for book types compared to typically developing children in the early years of development. Providing preschoolers with a range of book types during the preschool years will help to facilitate early language and emergent literacy skills.

Published: December 2019

AbstractThe current research of seawater hydraulic motor mainly focused on piston motor and vane motor, but seldom regarded low speed high torque seawater hydraulic motor. Low speed high torque seawater hydraulic motor as a kind of energy conversion device and actuator plays an important role in seawater hydraulic transmission system. However, the physical and chemical properties of seawater, such as low viscosity, high causticity and poor lubrication, result in numerous problems. In this paper, the flow distribution characteristics of port plate pairs for the seawater hydraulic motor are investigated, and the leakage flow and power loss models of port plate pairs are established. Numerical simulations are carried out to examine the effects of water film, inlet pressure and rotating speed on the pressure distribution and leakage flow. And the friction and wear tests of port plate pairs are also carried out. Moreover, the test system of the seawater hydraulic motor is constructed and the performance of prototype with no-load or loading is conducted. The results indicate that the clearance of port plate pairs and inlet pressure have a significant effect on distribution characteristics, but the effect of rotating speed is not very obvious. The experimental results show that the minimum error rate can be maintained within 0.3% by the proposed flow model and the counter materials of 316L against carbon-fiber-reinforced polyetheretherketone (CFRPEEK) are suitable for the port plate pairs of seawater hydraulic motor. Finally, based on the seawater hydraulic experiment platform, the volumetric efficiency of no-load and loading are obtained that the maximum can achieve 94.71% and 90.14%, respectively. This research work may improve the flow distribution performance, lubrication and the friction and wear properties, enhance energy converting efficiency of port plate pair and provide theoretical and technical support for the design of high-performance water hydraulic components.

Published: December 2019

AbstractThe control of the polarization states of light plays an important role in modern optical systems. However, traditional polarization manipulating devices often have narrow bandwidth and their large size makes it difficult for them to achieve miniaturization and integration of optical systems. This work presents an ultrathin quarter waveplate with a periodic silver film 2 × 2 rectangular hole array with a thickness less than λ/50. Numerical simulation shows that the waveplate can efficiently transform a circular polarized wave into a linearly polarized one at the center of 1550 nm, and its bandwidth is 525 nm. Furthermore, the quarter waveplate can efficiently invert linear polarization into circular polarization at 1550 nm, which ellipticity is near unit. With an array of small holes on a metal film to enhance transmission, this structure can increase the transmission to 0.44. The broadband quarter waveplate can be used in communication system and near infrared band system, and be integrated with other optical devices at nanoscale to achieve polarization operation, detection, and sensing.

Published: December 2019

Abstract
Background
Little is known regarding the functional role of microRNA-410 (miR-410) in osteonecrosis of the femoral head (ONFH); hence, the aim of the present study was to investigate miR-410 targeting Wnt-11 to modulate the osteogenic and osteoclastic mechanism in the prevention of ONFH.

Methods
Fifteen ONFH samples and 15 normal samples were gathered. The pathological changes of the femoral head, osteoblasts, and osteoclasts in the clinical samples were observed. The rat model of ONFH was injected with agomir-miR-410, Wnt-11-siRNA, or oe-Wnt-11. MiR-410; Wnt-11; osteoblast-related factors alkaline phosphatase (ALP), bone gamma-carboxyglutamate protein (BGLAP), and Collα1 expression; and osteoclast-related factors acid phosphatase 5 (ACP5), cathepsin K (CTSK), and MMP9, as well as Bcl-2 and Bax expression, were tested by RT-qPCR and western blot analysis. The osteogenic function index ALP and OCN together with osteoclast function index NTX-1 and CTX-1 in serum was tested by ELISA.

Results
MiR-410, ALP, BGLAP, and Collα1 degraded as well as Wnt-11, ACP5, CTSK, and MMP9 enhanced in ONFH tissues of the clinical samples. Upregulated miR-410 and downregulated Wnt-11 enhanced bone mineral density (BMD) and BV/TV of rats, heightened the BMD level of the femoral shaft, femoral head, and spinal column, and also raised the serum calcium and phosphorus levels of rats, while restrained apoptosis of osteocytes, elevated OCN, ALP, BGLAP, and Collα1 expression and declined ACP5, CTSK, NTX-1, CTX-1, and MMP9 expression in rats.

Conclusion
This study suggested that upregulating miR-410 or downregulating Wnt-11 increases osteoblasts and reduces osteoclasts to alleviate the occurrence of ONFH. Thus, miR-410 may serve as a potential target for the treatment of ONFH.

Published: December 2019

Abstract
Background
Quantitative areas is of great measurement of wound significance in clinical trials, wound pathological analysis, and daily patient care. 2D methods cannot solve the problems caused by human body curvatures and different camera shooting angles. Our objective is to simply collect wound areas, accurately measure wound areas and overcome the shortcomings of 2D methods.

Results
We propose a method with 3D transformation to measure wound area on a human body surface, which combines structure from motion (SFM), least squares conformal mapping (LSCM), and image segmentation. The method captures 2D images of wound, which is surrounded by adhesive tape scale next to it, by smartphone and implements 3D reconstruction from the images based on SFM. Then it uses LSCM to unwrap the UV map of the 3D model. In the end, it utilizes image segmentation by interactive method for wound extraction and measurement. Our system yields state-of-the-art results on a dataset of 118 wounds on 54 patients, and performs with an accuracy of 0.97. The Pearson correlation, standardized regression coefficient and adjusted R square of our method are 0.999, 0.895 and 0.998 respectively.

Conclusions
A smartphone is used to capture wound images, which lowers costs, lessens dependence on hardware, and avoids the risk of infection. The quantitative calculation of the 3D wound area is realized, solving the challenges that 2D methods cannot and achieving a good accuracy.

Authors: Zhao Zhanqiang , Li Bing , Wu Yuqing , Chen Xujun , Guo Yan , Shen Yang , Huang He 
Published: December 2019

Abstract
Background
Ketamine has been reported to cause neonatal neurotoxicity in a variety of developing animal models. Various studies have been conducted to study the mechanism of neurotoxicity for general anesthetic use during the neonatal period. Previous experiments have suggested that developmentally generated granule neurons in the hippocampus dentate gyrus (DG) supported hippocampus-dependent memory. Therefore, this study aimed to investigate whether ketamine affects the functional integration of developmentally generated granule neurons in the DG. For this purpose,the postnatal day 7 (PND-7) Sprague-Dawley (SD) rats were divided into the control group and the ketamine group (rats who received 4 injections of 40 mg/kg ketamine at 1 h intervals). To label dividing cells, BrdU was administered for three consecutive days after the ketamine exposure; NeuN+/BrdU+cells were observed by using immunofluorescence. To evaluate the developmentally generated granule neurons that support hippocampus-dependent memory, spatial reference memory was tested by using Morris Water Maze at 3 months old, after which the immunofluorescence was used to detect c-Fos expression in the NeuN+/BrdU+ cells. The expression of caspase-3 was measured by western blot to detect the apoptosis in the hippocampal DG.

Results
The present results showed that the neonatal ketamine exposure did not influence the survival rate of developmentally generated granule neurons at 2 and 3 months old, but ketamine interfered with the integration of these neurons into the hippocampal DG neural circuits and caused a deficit in hippocampal-dependent spatial reference memory tasks.

Conclusions
In summary, these findings may promote more studies to investigate the neurotoxicity of ketamine in the developing brain.
Spontaneous bladder rupture secondary to warfarin overdose: a case report
Authors: Sahin Taner , Oner Ufuk , Baser Omer , Kurtuncu Ismail 
Published: December 2019

Abstract
Background
Warfarin, a vitamin K antagonist, is a widely used medication for the treatment and prophylaxis of thromboembolic events. Patients with various clinical conditions due to warfarin overdose present to emergency departments. Although there may be serious bleeding due to a warfarin overdose, no bleeding may also be seen in some clinical conditions. Some of these bleedings may be life-threatening and result in death. Warfarin overdose and related cases of spontaneous bladder rupture are not frequently observed in the literature. We present a case of spontaneous bladder rupture due to warfarin overdose that was unexpectedly seen in a patient using warfarin for coronary artery disease and arrhythmia.

Case presentation
A 77-year-old Caucasian male patient was admitted to the emergency department with abdominal pain, haematuria, and a reduced volume of urine lasting for three days. The patient’s amount of urine was reduced, and he came to the hospital for the first time with this complaint. The patient had local bruises on his arms and legs. From the ultrasound, retrograde cystography and computed tomography images, it was thought that there was blood accumulation due to bladder rupture to the intraperitoneal region. Spontaneous bladder rupture secondary to warfarin overdose was considered for this patient who also had an international normalized ratio (INR) level of 13.4. After the INR level was normalized with vitamin K and a prothrombin complex concentrate, the patient underwent surgery. During the operation, a catheter was placed in the bladder, and the bladder mucosa and muscle were closed separately with a primary repair performed by a urologist. The patient was discharged on the 8th postoperative day without any complications.

Conclusion
In addition to the known findings of warfarin overdose in these patients presenting to the emergency department, we think that the emergency department staff should suspect bladder rupture, which is a fatal complication in the presence of signs such as oliguria, haematuria, anuria, abdominal pain, and syncope.

Published: December 2019

Abstract
Background
A simpler method for detecting atherosclerosis obliterans is required in the clinical setting. Laser Doppler flowmetry (LDF) is easy to perform and can accurately detect deterioration in skin perfusion. We performed LDF for hemodialysis patients to determine the correlations between blood flow in the lower limbs and peripheral arterial disease (PAD).

Methods
This retrospective study included 128 hemodialysis patients. Patients were categorized into the non-PAD group (n = 106) and PAD group (n = 22), 14 early stage PAD patients were included in the PAD group. We conducted LDF for the plantar area and dorsal area of the foot and examined skin perfusion pressure (SPP) during dialysis.

Results
SPP-Dorsal Area values were 82.1 ± 22.0 mmHg in the non-PAD, and 59.1 ± 20.3 mmHg in PAD group, respectively (p < 0.05). The LDF-Plantar blood flow (Qb) values were 32.7 ± 15.5 mL/min in non-PAD group and 21.5 ± 11.3 mL/min in PAD group (p < 0.001). A total of 21 non-PAD patients underwent LDF before and during dialysis. The LDF-Plantar-Qb values were 36.5 ± 17.6 mL/min before dialysis and 29.6 ± 17.7 mL/min after dialysis (p < 0.05). We adjusted SPP and LDF for PAD using logistic regression, SPP-Dorsal-Area and LDF-P were significantly correlated with PAD (p < 0.05). The receiver-operating characteristic curve analysis indicated cut-off values of 20.0 mL/min for LDF-Plantar-Qb during dialysis.

Conclusion
LDF is a simple technique for sensitive detection of early-stage PAD. This assessment will help physicians identify early-stage PAD, including Fontaine stage II in clinical practice, thereby allowing prompt treatment.
Crescentic poststreptococcal acute glomerulonephritis accompanied by small vessel vasculitis: case report of an elderly male
Authors: Yano Keiko , Suzuki Hiroyuki , Oda Takashi , Ueda Yoshihiko , Tsukamoto Tatsuo , Muso Eri 
Published: December 2019

Abstract
Background
Poststreptococcal acute glomerulonephritis (PSAGN) in the elderly tends to have a severe clinical course and often presents with crescentic necrotizing glomerulonephritis in the renal biopsy. However, vasculitis lesions are unusual.

Case presentation
We present a 71-year-old man who was admitted to our hospital for a recurrent gout attack with a rapid decline of renal function. Low C3 levels and a high anti-streptolysin O titer were observed, while myeloperoxidase- and proteinase 3- antineutrophil cytoplasmic antibody (ANCA) were negative. In addition to cellular crescent and necrosis lesions, diffuse peritubular capillaritis and venulitis as well as small arteriole vasculitis in the glomerular hilus were also apparent. Although granular C3c deposits in the capillary wall and hump lesions were not found, immunofluorescent staining for nephritis-associated plasmin receptor (NAPlr) and in situ zymography for plasmin activity were both positive. We thus diagnosed PSAGN accompanied by small vessel vasculitis. Steroid therapy gradually improved the patient’s renal function, and hemodialysis was discontinued after 1 month.

Conclusions
In our case, streptococcus infection might have concurrently provoked vasculitis, and NAPlr staining was useful for confirming diagnosis.
