Objective Application of aerogels in bone tissue engineering is an emerging field, while the reports of electrospinning nanofiber-reinforced aerogels are limited. This research aimed at fabricating the nanofiber-reinforced aerogels and evaluating their physiochemical and biological properties. Approach The chitosan (CS) aerogels incorporated with cellulose acetate (CA) and poly (ɛ-caprolactone) (PCL) nanofibers were fabricated via ball milling and freeze-drying techniques. Scanning electron microscopy (SEM), Fourier transform infrared (FT-IR) spectrum, X-ray photoelectron spectroscopy (XPS), compressive experiment, and in vitro experiment were conducted to assess their physiochemical properties and biological behavior. Results The SEM examination showed that satisfying morphology was attained in the CA/PCL/CS aerogels with incorporation of CA/PCL nanofibers and CS solution. The results of FT-IR and XPS indicated the perfect incorporation of CA, PCL, and CS. A compressive experiment confirmed that the CA/PCL/CS aerogels enhanced the compressive modulus of the pure CS aerogel. For in vitro experiment, the CA/PCL/CS composite scaffolds were proven to possess better cytocompatibility compared with the pure CS. Also, cells on the CA/PCL/CS showed well-extended morphology and could infiltrate into a porous scaffold. Furthermore, confocal experiment revealed that the CA/PCL/CS could also promote the osteogenic differentiation of MC3T3-E1 cells. Innovation This study fabricated the nanofiber-reinforced aerogels mainly to optimize the cell/material interaction of the pure CS scaffold. Conclusion The CA/PCL nanofibers not only improved the mechanical property of the CS aerogel to some extent but also facilitated cell adhesion and osteogenic differentiation. Thus, it could be considered a promising candidate for bone tissue engineering.Background Documentation and navigation through electronic health records (EHRs) is an essential, but stressful, task. We present the magnitude, determinants of such events, and solutions proposed by nurses to address EHR-related stress (EHR-S) at a tertiary eye hospital in Saudi Arabia. Methods Nurses of an eye hospital were surveyed in 2019 about EHR-S. A Likert scale was used to assess the responses of 10 components of EHR-related work. The total score was graded as follows minimum (11). The score was correlated with determinants. Solutions suggested by nurses to reduce stress were reviewed. Results This survey covered 212 nurses. Of them, 106 (50%; 95% confidence interval 43.3-56.7) reported EHR-S. The median EHR-S score was -3.0 (interquartile range -9.0; +8.0). Thirty-five (16%) nurses reported severe EHR-S. Senior nurses (M-W, p less then 0.02) and those working in emergency and recovery units (M-W, p less then 0.01) had statistically higher EHR-S. The main stressors were incomplete EHR work by other departments affecting nursing care (70.8%), difficulty in correction after entering the data (60.4%), and difficulty in data retrieval (60.4%). The main solutions to reduce EHR-S were to reduce the frequency of changes to configuration of the EHR (58%), more training (54.2%), and appreciation of good work (52.8%). Conclusions EHR-S is experienced by half of the nurses working at an eye care hospital. Implementation of solutions such as better training and fewer changes to the EHR system could reduce stress levels of nurses.Background Gas-forming pyogenic liver abscess (GFPLA) accounts for up to 30% of all pyogenic liver abscess (PLA) cases. However, little is known of the differences in clinical features and prognosis between GFPLA and non-GFPLA. Aim This retrospective study compared the clinical features and prognosis of GFPLA and non-GFPLA. Patients and Methods Data for 392 patients with PLA treated from January 1, 2007 to December 31, 2016 were reviewed. Gas-forming pyogenic liver abscess was defined as gas in the abscess. Liver abscesses were considered non-GFPLA (n = 326) or GFPLA (n = 66). Baf-A1 The clinical features and outcomes of patients with GFPLA were compared with that of patients without GFPLA. Results The groups were similar in gender ratio, age, smoking, drinking, and comorbidities. Klebsiella pneumoniae was the most common pathogenic bacteria, but the negative rate of bacterial culture of the non-GFPLA group was higher than that of the GFPLA. In etiologies, the GFPLA group had more biliary source infection and less cclinical entity.The purpose of this study was to characterise lower-limb joint kinetics during consecutive double unders and speed step sprints performed by competitive jump rope athletes, and to compare these measurements to running. Sixteen adolescent competitive jump rope athletes performed consecutive double under, speed step, and running trials while motion capture and ground reaction force data were collected. Lower-limb joint moments, power, and work were calculated using an inverse dynamics approach and discrete measurements were compared between skills. Peak ground reaction forces were similar between movements; however, knee and hip joint kinetics were distributed differently between double unders and speed step. In general, double unders were characterised by an increased reliance on knee joint kinetics, while speed step was characterised by an increased reliance on hip joint kinetics. Peak ankle moments were 9-20% greater in speed step when compared to double unders and running (p ≤ 0.050), and peak negative ankle power was 39-114% greater in double unders and speed step when compared to running (p ≤ 0.002). These findings may have important implications for injury risk and load management in jump rope athletes or other individuals that incorporate jump rope into their training programs.Technology has played an important role in responding to the novel coronavirus (SARS-CoV-2) and subsequent COVID-19 pandemic. The virus's blend of lethality and transmissibility have challenged officials and exposed critical limitations of the traditional public health apparatus. However, throughout this pandemic, technology has answered the call for a new form of public health that illustrates opportunities for enhanced agility, scale, and responsiveness. The authors share the Microsoft perspective and illustrate how technology has helped transform the public health landscape with new and refined capabilities - the efficacy and impact of which will be determined by history. Technologies like chatbot and virtualized patient care offer a mechanism to triage and distribute care at scale. Artificial intelligence and high-performance computing have accelerated research into understanding the virus and developing targeted therapeutics to treat infection and prevent transmission. New mobile contact tracing protocols that preserve patient privacy and civil liberties were developed in response to public concerns, creating new opportunities for privacy-sensitive technologies that aid efforts to prevent and control outbreaks.
