Abstract
Background: Foot care knowledge and practices among nurses and care workers in the community greatly impact foot health maintenance and prevention of foot-related problems among older people. This study aimed to explore and examine the current foot care knowledge, practices, and perceptions among nurses and care workers at home care and adult day service center, along with their demographic characteristics and daily care for clients.Methods: This study analyzed 232 randomly selected front-line nurses and care workers working at home care or adult day service center in one of the selected cities, Aichi Prefecture, Japan. Data were obtained using questionnaires and subsequently analyzed using descriptive statistics, t-tests, Chi-square tests, Wilcoxon rank-sum tests, and Spearman’s rank correlation tests.Results: Among the 305 surveyed, 232 (62 nurses; 170 care workers) provided data. Although 57 nurses (91.9%) and 142 care workers (83.5%) showed interest in foot care, 33 nurses (53.2%) and 133 care workers (78.2%) stated that foot care education was insufficient. Knowledge and practice scores were associated with working status.Higher accuracy differences in the early detection of foot problems and skin tears on lower limbs in knowledge category were observed between nurses and care workers. The nurses as well as the care workers had low accuracy rates of knowledge questions regarding the use of shoes and socks subscale.For practice, both nurses and care workers had low mean scores for checking client’s shoes (2.0/5.0 and 2.1/5.0, respectively), method for reducing ingrown nail pain (2.6/5.0 and 1.9/5.0, respectively), and opportunity for discussing foot care with others (2.7/5.0 and 2.2/5.0, respectively). A significant correlation between knowledge and practice scores was observed among nurses (0.331, p < 0.05) and care workers (0.339, p < 0.001).Conclusions: Despite the presence of several barriers toward enhanced care delivery to clients needing it most, nurses and care workers clearly understood the importance of foot care. These findings indicate that foot care should be focused by nurses and care workers to improve the knowledge and practice of foot care and to suggest future implications that efficient and understandable tools are needed considering their current working situation.

Authors: wang meiyong , jin qunhua 
Published: July 2020

Abstract
Background: Bone cement leakage causes severe complication following percutaneous vertebroplasty. This study probed the diffusion and leakage status of bone cement injected within diverged time duration, so as to find the optimal injection time for bone cement. Methods: A total of 70 patients with osteoporotic vertebral compression fractures with a symptom of low back pain, who underwent treatment at hospital were enrolled in this study. Patients were randomized into three groups: <180 s, 180-300, and >300 s of injection time duration from the beginning to the completion of the injection. The scenarios of vertebral bone cement leakage and diffusion were inspected using postoperative CT.Results: The diffusion coefficient was higher in group A than in group B whereas it was higher in group B than in group C, but without statistical significance among the three groups. The leakage rate was without statistical significance among the three groups. The injection time of bone cement was negatively correlated with the diffusion coefficient, at the correlation coefficient of -0.253. Conclusions: The diffusion coefficient of high-viscosity bone cement is negatively correlated with the injection time, and the leakage rate of high-viscosity bone cement does not reduce with the prolongation of injection time.

Abstract
Background: In the Twin Birth Study, women at 320/7-386/7 weeks of gestation, in whom the first twin was in cephalic presentation, were randomized to planned vaginal delivery or cesarean section. The study found no significant differences in neonatal or maternal outcomes in the two planned mode of delivery groups. We aimed to compare neonatal and maternal outcomes of twin gestations without spontaneous onset of labor, who underwent induction of labor or pre-labor cesarean section as the intervention of induction may affect outcomes.Methods: In this secondary analysis of the Twin Birth Study we compared those who had an induction of labor with those who had a pre-labor cesarean section. The primary outcome was a composite of fetal or neonatal death or serious neonatal morbidity. Secondary outcome was a composite of maternal morbidity and mortality. Trial Registration: NCT00187369Results: Of the 2,804 women included in the Twin Birth Study, a total of 1,347 (48%) women required a delivery before a spontaneous onset of labor occurred: 568 (42%) in the planned vaginal delivery arm and 779 (58%) in the planned cesarean arm. Induction of labor was attempted in 409 (30%), and 938 (70%) had a pre-labor cesarean section. The rate of intrapartum cesarean section in the induction of labor group was 41.3%. The rate of the primary outcome was comparable between the pre-labor cesarean section group and induction of labor group (1.65% vs. 1.97%; p=0.61; OR 0.83; 95% CI 0.43-1.62). The maternal composite outcome was found to be lower with pre-labor cesarean section compared to induction of labor (7.25% vs. 11.25%; p=0.01; OR 0.61; 95% CI 0.41-0.91). Conclusion:In women with twin gestation between 320/7-386/7 weeks of gestation, induction of labor and pre-labor cesarean section have similar neonatal outcomes. Pre-labor cesarean section is associated with favorable maternal outcomes which differs from the overall Twin Birth Study results. These data may be used to better counsel women with twin gestation who are faced with the decision of interventional delivery.

Abstract
Background: The clinical characteristics and outcomes of the 2019 novel coronavirus (COVID-19) pneumonia are different in Hubei compared to other regions in China. But there are few comparative studies on the differences between imported and local patients which may provide information of the different courses of the virus after transmission. Methods: We investigated 169 cases of COVID-19 pneumonia in two centers in Hunan Province, and divided them into two groups according to epidemiological history, "imported patients" refers to patient with a clear history of travel in Wuhan within 14 days before onset, and " local patients” refers to local resident without a recent history of travel in Wuhan, aiming to analyze the difference in clinical characteristics and outcomes between the two groups. All the epidemiological, clinical, imaging, and laboratory data were analyzed and contrasted. Results: The incidence of fever on admission in imported patients was significantly higher than local patients. There was a significantly higher proportion of abnormal pulmonary signs, hypokalemia, hyponatremia, prolonged PT, elevated D-dimer and elevated blood glucose in imported patients. Compared with local patients, the proportion using antibiotics, glucocorticoids and gamma globulin were significantly higher in imported patients. The moderate type was more common in local patients, and the severe type were more frequent in imported patients. In addition, the median duration of viral clearance was longer in imported patients. Conclusions: In summary, we found that imported cases were more likely to develop into severe cases, compared with local patients and required more powerful treatments.Trial registration: Registered 21st March 2020, and this study has been approved by the Medical Ethics Committee (Approved Number. 2020017).

Published: July 2020

Abstract
Background: Dry eye syndrome in which tear fluid quality or abnormality or kinetic abnormality is caused by many causes, resulting in decreased tear film stability. In recent years, more and more results from the studies indicate that miRNA alterations are involved in dry eye syndrome. And miRNA-146a-5p is a key regulator to regulate the inflammatory response. In this paper, we demonstrated whether miRNA-146a-5p could cure dry eye syndrome by regulating target genes based on network analysis.Methods: In this paper, we collected the blood of patients with dry eye disease which served as a model group, the blood of healthy people was used as a control group. The expression of miRNA-146a-5p in the patients was detected by RT-PCR, the genes controlled by miRNA-146a-5p were predicted by Targetscan, miRDB, miRWalk and PicTar databases, the genes regulated by miRNA-146a-5p which is related to dry eye disease were selected by draw Venn diagram;Results: The comparison of the general information between patients and healthy people was no significant difference, and it indicated that the two groups were comparable. The results of databases showed that IRAK1 was one of the target genes regulated by miRNA-146a-5p and it is related to dry eye disease. The expression of miRNA-146a-5p was negatively related to IRAK1 mRNA and protein. While IRAK1 had positive correlation with IL-6, TNF-α and CBP proteins. Conclusion: These results emphasized that miRNA-146a-5p could inhibit the expression of IRAK1, IL-6, TNF-α and CBP so as to help reduce the inflammatory response in dry eye syndrome.

Abstract
Background: Although serum albumin levels are increasingly used as an indicator of nutritional status in the clinic, the relationship between perioperative hypoalbuminemia and wound complications after posterior lumbar interbody fusion in the treatment of lumbar degenerative disease remains ambiguous. The aim of this study was to evaluate perioperative serum albumin in relation to postoperative wound complications after posterior lumbar interbody fusion in the treatment of single-segment lumbar degenerative disease. Material and methods: We reviewed patients who underwent single-segment posterior lumbar interbody fusion surgery from December 2014 to April 2017 in the Department of Orthopedics at the First Affiliated Hospital of Chongqing Medical University. Perioperative (preoperative and early postoperative) serum albumin levels were assessed in all patients and were used to quantify nutritional status. We divided the patients into a surgical wound dehiscence (SWD) group and a normal wound healing group, and into a surgical site infection(SSI)group and a non-SSI group. To evaluate the relationship between perioperative serum albumin level and postoperative wound complications, we conducted univariate and multiple logistic regression analyses.Results: A total of 554 patients were enrolled in the study.The univariate and multiple logistic regression analysis of these differences showed that preoperative serum albumin <3.5 g/dl and postoperative serum albumin:<3.0 g/dl were significantly related to SWD (P<0.05). There were also significant differences between the surgical site infection(SSI) groups in terms of preoperative serum albumin <3.5 g/dl(P=0.001), postoperative serum albumin <3.5 g/dl (P<0.023) and <3.0 g/dl(P<0.001).Additionally, the increased hospitalization costs and length of hospitalization were statistically significant for patients with perioperative hypoalbuminemia. Conclusions: For patients who underwent single-segment posterior lumbar interbody fusion surgery, we need to pay more attention to steroid use, perioperative hypoalbuminemia, which are more likely to be associated with increased wound complications, hospitalization costs and length of hospitalization after surgery. Adequate assessment and management of these risk factors will help reduce wound complications and hospital stays for surgical patients and will save medical costs.
MicroRNA-214-3p Inhibits the Stem-Like Properties of Lung Squamous Cell Cancer by Targeting YAP1
Authors: Lu Tingting , Yang Ying , Li Ziming , Lu Shun 
Published: July 2020

Abstract
Background: Emerging evidence reveals that microRNAs (miRNAs) play a crucial role in tumor progression, but the underlying mechanism of microRNAs in lung squamous cell cancer (LSCC) remains unclear. Method : Western-blotting and quantitative real-time PCR (q-PCR) were carried out to detect mRNA and protein expression. Cell proliferation was evaluated by Cell Counting Kit-8 (CCK-8), colony-forming assay or sphere-forming assay, respectively. Results: MiR-214-3p was markedly de-regulated in LSCC tissues and was inversely related to the level of Yes-associated protein1 (YAP1), which is the core transcription regulator of the Hippo signaling pathway. Kaplan-Meier survival curves illustrated that patients with high miR-214-3p expression demonstrated more favorable clinical outcomes. MiR-214-3p overexpression (OE) repressed proliferation and cancer stem-like cells (CSCs) properties in vitro and in vivo xenograft mouse model. Mechanistically, luciferase activity assay revealed that miR-214-3p directly targets YAP1 by specifically binding on the 3’ UTR of YAP1. Conclusion: MiR-214-3p plays a pivotal role in CSCs properties by targeting YAP1, which provides a potential treatment strategy for LSCC patients.

Abstract
Background: We assessed the quantitative changes in muscle mass and strength during two weeks of hospitalization in immobile and mobile acutely ill hospitalized older adults.Methods: 41 patients (82.4±6.6 years, 73.0% females) participated in this prospective longitudinal observational study. Mobility status was defined according to walking ability as described in the Barthel-Index. Functional status, including handgrip strength and isometric knee-extension strength, and mid-thigh magnetic resonance imaging measurements of cross-sectional area (CSA) were conducted on admission and at discharge. Results: Twenty-two participants (54%) were immobile and 19 (46%) mobile. In all, 54.0% and 12.0% were at risk of malnutrition and malnourished, respectively. The median time between baseline and follow-up for MRI scans were 13 days in mobile and immobile participants (P=0.072). Mid-thigh muscle and subcutaneous fat CSA significantly decreased by 3.9cm2 (5.0%, P=0.002) and 5.3cm2 (5.7%, P=0.036) during hospitalization whereas intermuscular fat remained unchanged in immobile subjects. No significant changes were observed in mobile patients. In a regression analysis, mobility was the major independent risk factor for changes in mid-thigh muscle CSA as a percentage of initial muscle area (P=0.022) whereas other variables such as age (P=0.584), BMI (P= 0.879), nutritional status (P=0.835) and inflammation (P=0.291) were not associated with muscle mass changes. There was a significant decrease in isometric knee extension strength (P=0.002) and no change in handgrip strength (P=0.167) in immobile patients whereas both parameters increased significantly over time in mobile patients (P=0.048 and P=0.012, respectively).Conclusions: Two weeks of disease-related immobilization result in a significant loss of thigh muscle mass and muscle strength in older patients with impaired mobility. Concomitantly, there was a significant reduction of subcutaneous adipose tissue in immobile older hospitalized patients whereas no changes were observed in intermuscular fat among these patients. These data should highlight the importance of mobility support in maintaining muscle mass and function in older hospitalized patients.
Comparison of overall survival of gastric neoplasms containing neuroendocrine carcinoma components with gastric adenocarcinoma: a propensity score matching study

Published: July 2020

Abstract
Background Gastric neoplasms containing neuroendocrine carcinoma (NEC) components are rare malignancies with highly aggressive behavior and a poor prognosis and include pure NEC and mixed tumors containing NEC components. We aimed to investigate whether there is a distinct difference in overall survival (OS) between gastric neoplasms containing NEC components and gastric adenocarcinoma.Methods Surgically resected gastric neoplasms containing NEC components (n=180) and gastric adenocarcinomas (n=785) from January 2013 to December 2019 at Peking University Cancer Hospital were retrospectively analysed. Patients were categorized into a surgical group and a neoadjuvant group and adjusted using propensity score matching. In the two groups, gastric neoplasms containing NEC components were divided into pure NEC and mixed tumors with less than 30% (<30% G-HMiNEN), between 30% and 70% (G-HMiNEN) and more than 70% (>70% G-HMiNEN) neuroendocrine carcinoma components. OS was compared between these groups and the gastric adenocarcinoma group.Results The OS of gastric neoplasms containing neuroendocrine NEC components was poorer than that of gastric adenocarcinomas in the surgical group, regardless of whether the percentage of neuroendocrine cancer components was less than 30%, between 30% and 70%, more than 70% or 100%. Cox multivariable regression analysis suggested that tumor category (neoplasms containing NEC components or gastric adenocarcinoma) was an independent risk factor for prognosis. Interestingly, among patients receiving neoadjuvant therapy, the difference was not significant.Conclusions Gastric neoplasms containing any proportion of NEC components had poorer overall survival than gastric adenocarcinoma in patients treated with surgery directly, indicating that these neoplasms are more malignant than gastric adenocarcinoma. Among the patients receiving neoadjuvant therapy, the difference in overall survival was not significant, which was in sharp contrast with the results of the surgery group, suggesting that neoadjuvant therapy may have a good effect in the treatment of these neoplasms.

Abstract
Background: People with acquired brain injury may suffer from cognitive, emotional and behavioural changes in the long term. Continuity of care is often lacking, leading to a variety of unmet needs and hindering psychosocial functioning from the occurrence of brain injury up to years thereafter. Case management aims to prevent (escalation of) problems and to facilitate timely access to appropriate services. In other populations, case management has shown to improve psychosocial well-being. In this study, we aim to evaluate the feasibility of case management after acquired brain injury and its effectiveness and cost-effectiveness, compared to care as usual.Methods: This is a pragmatic randomized controlled study with repeated measures in adults with ABI and their family, taking place between November 2019 and December 2021 in three provinces in the Netherlands. Participants will be randomly allocated to either the case management group, receiving case management from hospital discharge up to two years thereafter, or the control group, receiving care as usual. Effectiveness will be evaluated every six months for 18-24 months by patient-reported psychosocial well-being (Hospital Anxiety and Depression Scale (HADS), Utrecht Scale for Evaluation of Rehabilitation-Participation (USER-P) restriction subscale and the Life Satisfaction Questionnaire (LiSat)), self-management (Patient Activation Measure (PAM)) and care needs (Longer-term Unmet Needs after Stroke (LUNS)). Family outcomes include self-efficacy (Carer Self-Efficacy Scale (CSES)), caregiver burden (Caregiver Strain Index (CSI)), psychosocial well-being (LiSat, HADS), family needs (Family Needs Questionnaire (FNQ)). Feasibility will be evaluated using qualitative methods, assessing fidelity, dose delivered, dose received, reach, recruitment and context. Cost-effectiveness will be determined by the EQ-5D-3L and service use.Discussion: At the moment there is no integrated health care service for people with acquired brain injury and their family members in the long-term. If case management is shown to be feasible and (cost)-effective, it could bridge the gap between patients’ and families’ needs and the available services.Trial registration: Netherlands Trial Register, NL8104.

Published: July 2020

Abstract
Background: To develop and validate an MRI-based radiomics nomogram for differentiation of cervical spine ORN from metastasis after radiotherapy (RT) in nasopharyngeal carcinoma (NPC).Methods: A radiomics nomogram was developed in a training set that comprised 46 NPC patients after RT with 95 cervical spine lesions (ORN, n = 51; metastasis, n = 44), and data were gathered from January 2008 to December 2012. 279 radiomics features were extracted from the axial contrast-enhanced T1-weighted image (CE-T1WI). A radiomics signature was created by using the least absolute shrinkage and selection operator (LASSO) algorithm. A nomogram model was developed based on the radiomics scores. The performance of the nomogram was determined in terms of its discrimination, calibration, and clinical utility. An independent validation set contained 25 consecutive patients with 47 lesions (ORN, n = 25; metastasis, n = 22) from January 2013 to December 2015. Results: The radiomics signature that comprised eight selected features was significantly associated with the differentiation of cervical spine ORN and metastasis. The nomogram model demonstrated good calibration and discrimination in the training set [AUC, 0.725; 95% confidence interval (CI), 0.622–0.828] and the validation set (AUC, 0.720; 95% CI, 0.573–0.867). The decision curve analysis indicated that the radiomics nomogram was clinically useful.Conclusions: MRI-based radiomics nomogram shows potential value to differentiate cervical spine ORN from metastasis after RT in NPC.
