Wireless magnetic microrobots are envisioned to revolutionize minimally invasive medicine. While many promising medical magnetic microrobots are proposed, the ones using hard magnetic materials are not mostly biocompatible, and the ones using biocompatible soft magnetic nanoparticles are magnetically very weak and, therefore, difficult to actuate. Thus, biocompatible hard magnetic micro/nanomaterials are essential toward easy‐to‐actuate and clinically viable 3D medical microrobots. To fill such crucial gap, this study proposes ferromagnetic and biocompatible iron platinum (FePt) nanoparticle‐based 3D microprinting of microrobots using the two‐photon polymerization technique. A modified one‐pot synthesis method is presented for producing FePt nanoparticles in large volumes and 3D printing of helical microswimmers made from biocompatible trimethylolpropane ethoxylate triacrylate (PETA) polymer with embedded FePt nanoparticles. The 30 μm long helical magnetic microswimmers are able to swim at speeds of over five body lengths per second at 200 Hz, making them the fastest helical swimmer in the tens of micrometer length scale at the corresponding low‐magnitude actuation fields of 5–10 mT. It is also experimentally in vitro verified that the synthesized FePt nanoparticles are biocompatible. Thus, such 3D‐printed microrobots are biocompatible and easy to actuate toward creating clinically viable future medical microrobots. [ABSTRACT FROM AUTHOR]

Magnetic microswimmers are promising devices for biomedical and environmental applications. Bacterium flagella‐inspired magnetic microhelices with perpendicular magnetizations are currently considered standard for propulsion at low Reynolds numbers because of their well‐understood dynamics and controllability. Deviations from this system have recently emerged: randomly shaped magnetic micropropellers with nonlinear swimming behaviors show promise in sensing, sorting, and directional control. The current progresses in 3D micro/nanoprinting allow the production of arbitrary 3D microstructures, increasing the accessible deterministic design space for complex micropropeller morphologies. Taking advantage of this, a shape is systematically reproduced that was formerly identified while screening randomly shaped propellers. Its nonlinear behavior, which is called frequency‐induced reversal of swimming direction (FIRSD), allows a propeller to swim in opposing directions by only changing the applied rotating field's frequency. However, the identically shaped swimmers do not only display the abovementioned swimming property but also exhibit a variety of swimming behaviors that are shown to arise from differences in their magnetic moment orientations. This underlines not only the role of shape in microswimmer behavior but also the importance of determining magnetic properties of future micropropellers that act as intelligent devices, as single‐shape templates with different magnetic moments can be utilized for different operation modes.

Abstract Background and Aims: To examine the functional impact of upper gastrointestinal endoscopy as a day procedure, particularly in relation to subsequent school attendance. Methods: Symptoms and morbidities were prospectively recorded from school-aged children during observation in hospital and for 3 days at home after endoscopy by using a structured questionnaire. Reasons for school absence were identified. Results: Sixty children (31 boys, 29 girls) were enrolled in the study (mean age 10.6 ± 2.8 years, range 6.1–16.2 years). Following the procedure, symptoms were reported at home in 68.3% (same day), 56.7% (day 1) and 20% (day 2). The commonest symptoms were sore throat, tiredness and dizziness. Twenty-nine children (48.3%) did not attend school on the day following the procedure but most (26 of 29) had returned to school by the second day. The main reason for their absence was residual physical discomfort related to the procedure (55.2%). Conclusions: Persisting physical discomfort and school absenteeism are common following upper gastrointestinal endoscopy in children. [ABSTRACT FROM AUTHOR]

ABSTRACT Responding to health care needs of the elderly has presented great challenges for health care professionals. These problems are compounded in rural communities by physical and social isolation, increased poverty, and lack of transportation. An innovative approach to meeting health needs of rural elderly is through nursing centers. Through an emphasis on health promotion and maintenance of optimal level of functioning, these primary health care facilities can foster independence and self-care for this targeted population. In addition, nursing centers serve as clinical sites for student learning experiences and settings for nursing research. This article focuses on a nursing center established at Edinboro University of Pennsylvania (EUP), which tailors its services to the elderly living in Edinboro. Results of a client satisfaction survey, based on the Risser Patient Satisfaction Instrument, are described in addition to patterns of nursing center usage, general categories of care, teaching interventions, referrals, counseling, and frequency of visits. Findings from the survey indicated a general high client satisfaction level with nursing care received at the center. Discussion also includes plans to expand services to elderly in the community through home visits. [ABSTRACT FROM AUTHOR]
