To evaluate the level of parent-reported family resilience, parenting styles and psychosocial adjustment of children with chronic illness and to identify the relationships between family resilience, ...parenting styles and psychosocial adjustment in families with children with chronic illness.
A cross-sectional study was conducted between June 2019 and August 2019. A total of 236 parents of children with chronic illness and 98 parents with healthy children were recruited from general hospitals by convenience sampling. A parent completed the Chinese Family Resilience Assessment Scale, the Parenting Rearing Patterns Questionnaire and the Strengths and Difficulties Questionnaire. Family resilience, parenting styles, and psychosocial adjustment of children with chronic illness were compared with those of healthy children. Structural Equation Modeling (SEM) was performed to explore the mediation effect of parenting styles between family resilience and psychosocial adjustment among children with chronic illness.
Parents of children with chronic illness reported lower level of family resilience and authoritative parenting, but more peer relationship problems compared to parents of healthy children. SEM showed that authoritative parenting fully mediated the relationship between family resilience and psychosocial adjustment of children with chronic illness.
Childhood chronic illness reduces family resilience, authoritative parenting and children's psychosocial adjustment, but authoritative parenting mediated these effects, so authoritative parenting may be important for family resilience in families of children with chronic illness. Pediatric clinicians and nurses should provide family-centered interventions, as well as parenting training, to improve children's psychosocial outcomes.
Developing highly efficient and earth‐abundant electrocatalysts is urgent for oxygen evolution reaction (OER), and layered double hydroxides (LDHs) show great potentials as advanced electrocatalysts ...toward OER. However, the catalytic activity of LDHs is normally limited by their poor electronic conductivity and low electrochemical active areas. Herein, a novel sputtering–painting–alloying–dealloying strategy is reported to synthesize CoGa LDH anchored on stainless steel mesh (CoGa LDH/stainless steel mesh, SSM), in which abundant oxygen vacancies are introduced into the ultrathin CoGa LDH nanosheets. Owing to the unique painting‐like operation, the nanosheet‐decorated CoGa LDH/SSM electrode can be fabricated on a large scale (8 × 8 cm2 for instance), and possesses excellent flexibility and self‐supported feature. Free of any conducting/binder agents, the CoGa LDH/SSM electrode shows excellent electrocatalytic activity toward OER in an alkaline solution (low overpotential of 258 mV @ 10 mA cm−2, small Tafel slope of 34.1 mV dec−1, long‐term stability of 70 h), which is superior to that of state‐of‐the‐art Co‐based electrocatalysts. More importantly, the electrode needs only an overpotential of 198 mV to reach 10 mA cm−2 at 335 K. The OER performance of CoGa LDH/SSM can be rationalized by numerous oxygen vacancies, ultrathin nanosheet morphology, self‐supported nature, and low activation energy barrier.

Background: Little is known about how health behaviors cluster to form meaningful patterns that influence health outcomes in young adult nursing students. Purpose: The purpose of this study was to ...identify the unique health behavior patterns among young adult nursing students in China and examine the associations between health behaviors and chronic diseases. Methods: Using an electronic app, the achievements of an exercise target, sedentary behavior, smoking and drinking, and dietary patterns were assessed in 1,480 nursing student participants aged 18-24 years from two medical universities in Eastern China. Results: A four-class model was developed using latent class analysis that included the ＂failure to achieve exercise target, alcohol-drinking, and insufficient fruit and vegetable group＂ (Group 1, n = 187, 12.6%), the ＂alcohol-drinking and sedentary behavior group＂ (Group 2, n = 290, 19.6%), the ＂sedentary behavior only group＂ (Group 3, n = 721, 48.7%), and the ＂failure to achieve exercise target only group＂ (Group 4, n = 282, 19.1%). Logistic regressions indicated that nursing students in Group 2 (odds ratio OR = 0.42), Group 3 (OR = 0.51), and Group 4 (OR = 0.30) were less likely to have chronic diseases than those in Group 1 after adjusting for sociodemographic variables. Conclusions: The health behaviors were clustered in different patterns among young adult nursing students. Tailoring interventions to specific groups is suggested to improve health outcomes.

Circulating tumor cells (CTC) capture is one of the most effective approaches in diagnosis and treatment of cancers in the field of personalized cancer medicine. In our study, zwitterionic carboxybetaine methacrylate (CBMA) oligomers were grafted onto nylon via atomic transfer random polymerization (ATRP) which would serve as a novel material for the development of convenient CTC capture interventional medical devices. The chemical, physical and biological properties of pristine and modified nylon surfaces were assessed by Fourier transform infrared spectra, atomic force microscope, water contact angle measurements, X-ray photoelectron spectroscopy, protein adsorption, platelet adhesion, and plasma recalcification time (PRT) determinations, etc. The results, including the significant decrease of proteins adsorption and platelets adhesion, as well as prolonged PRTs demonstrated the extraordinary biocompatibility and blood compatibility of the modified surface. Furthermore, we showed that upon immobilization of anti-epithelial cell adhesion molecular (anti-EpCAM) antibody onto the CBMA moiety, the modified nylon surface can selectively capture EpCAM positive tumor cells from blood with high efficiency, indicating the potential of the modified nylon in the manufacture of convenient interventional CTC capture medical devices.
Here we propose an efficient estimation method to interpolate new samples in a blurred and aliased observation, in such a way that (1) aliasing artifacts in an ulterior restoration are mitigated, and ...(2) thanks to aliasing we may recover some spatial frequencies beyond the Nyquist frequency (super-resolution). The only requirement is having a good approximation of the blurring kernel in high resolution (HR). The method consists of two sequential steps: (1) to perform a Maximum Likelihood Interpolation, according to a Gaussian model; and (2) to apply a standard deconvolution to the interpolated image, using the HR blurring kernel in both steps. Simulations show strong improvements with respect to first deconvolving the unprocessed observation and then doing a standard interpolation with splines, and also with respect to first doing a standard interpolation and then deconvolving.
In order to quickly and accurately detect whether a chef is wearing a hat and mask, a kitchen standard dress detection method based on the YOLOv5s embedded model is proposed. Firstly, a complete ...kitchen scene dataset was constructed, and the introduction of images for the wearing of masks and hats allows for the low reliability problem caused by a single detection object to be effectively avoided. Secondly, the embedded detection system based on Jetson Xavier NX was introduced into kitchen standard dress detection for the first time, which accurately realizes real-time detection and early warning of non-standard dress. Among them, the combination of YOLOv5 and DeepStream SDK effectively improved the accuracy and effectiveness of standard dress detection in the complex kitchen background. Multiple sets of experiments show that the detection system based on YOLOv5s has the highest average accuracy of 0.857 and the fastest speed of 31.42 FPS. Therefore, the proposed detection method provided strong technical support for kitchen hygiene and food safety.
Pipeline pull-back load is an important basis for selecting power and checking capability of drilling equipment. In this paper, mechanical models of the pipeline hoisting outside and pulling inside ...the hole are established by the continuous beam theory, and relationships among various parameters are analyzed in the process of pull-back pipeline. The results show that there is a linear relationship between the lifting height of basket and the entry angle of hole. During the construction of the hoisting pipeline, the bending moment and shearing force of the basket position near the hole are larger, so the strength check of the pipeline only needs to do at this position. There is a linear relationship between the lifting height of the basket and the length of spanning pipeline. The lifting load and axial force of the pipeline vary linearly. The pull-back load of the pipeline varies curve in the arc segment of the trajectory. The pipeline pull-back load varies linearly in linear segment of trajectory.
Conventional in vitro circulating tumor cell (CTC) detection methods are always limited by blood sample volume because of the requirement of a large amount of blood. The aim of this study was to ...overcome the limitation by designing and making an in vivo CTC capture device. In this study, we designed and prepared a kind of proper material to serve the purpose of intervention. A method employing 3-aminopropyltriethoxysilane (γ-APS) as the coupling reagent to graft carboxybetaine methacrylate (CBMA) and to immobilize an anti-epithelial cell adhesion molecular (EpCAM) antibody on Nylon was developed. The results of X-ray photoelectron spectroscopy and Fourier transform infrared spectroscopy proved the successful graft of γ-APS and CBMA to Nylon. Furthermore, the predicted improvement in the biocompatibilities of our modified Nylon was confirmed by water contact angle measurement, bovine serum albumin adhesion, platelet adhesion, plasma recalcification time determination, and cytotoxicity tests. The tumor cells adhesion experiment revealed that Nylon with the antibody immobilized on it had an affinity for EpCAM positive tumor cells higher than that of pristine Nylon. Additionally, the capture ability of the CTCs was demonstrated in a nude mouse tumor model using the interventional device made of the modified Nylon wire. The positive results suggest that CBMA-grafted and anti-EpCAM antibody-immobilized Nylon is a promising new material for in vivo CTC capture devices.
First-year college students had exposure to unhealthy lifestyle behaviors that correlate with a high prevalence of anxiety and depression. Regarding to the modifiable lifestyle behaviors factors, ...this study investigated the prevalence and correlation of multiple lifestyle behaviors, anxiety and depression in a sample of Chinese first-year college students.
Cross-sectional data were extracted from Residents eHealth app of health lifestyle behaviors survey from September to October 2019.
