Coronavirus disease 2019 (COVID-19) has been recognized as a pandemic by the World Health Organization. Global efforts have been exerted to prevent the spreading of the disease through political decisions together with personal behaviors, which depend on awareness of the public. The goal of this study is to assess the knowledge, perceptions and attitude of the Egyptian public towards the COVID-19 disease. We conducted a cross-sectional survey about these points, which was distributed among adult Egyptians. Five hundred and fifty nine persons completed the survey. The mean knowledge score was 16.39 out of 23, gained mainly though social media (66.9%), and the internet (58.3%). Knowledge was significantly lower among older, less educated, lower income participants, and rural residents. Most participants (86.9%) were concerned about the risk of infection. While 37.6% thought that their salary will be continued if they become isolated, 68.5% believed that it should be continued during this period. About 73.0% were looking forward to get the vaccine when available. In general, participants had a good knowledge about the disease and a positive attitude towards protective measures. This knowledge is gained mainly through novel media channels, which have pros and cons. Although the government has taken major steps to educate the public and limit the spread of the disease, more effort is needed to educate and support the lower economic strata. If a vaccine or a treatment is approved, we recommend a government control over its use to preserve the rights of the vulnerable and needy groups.

The aim of the study was a comparison of robotic versus human laparoscopic camera control. Utilizing robotic technology a robot has been designed specifically for the purpose of holding and manoeuvring the laparoscope under the direct control of the surgeon. We tested AESOP (automated endoscopic system for optimal positioning) in 50 patients undergoing routine gynaecological endoscopic surgical procedures. The elimination of the camera holder allows two doctors to perform complex laparoscopic surgery faster than without the robotic arm. The timing of surgical procedures performed by surgeons using the voice control was compared to the timing of similar operations using the foot or hand control. The voice-controlled AESOP works more efficiently and faster than the hand or foot control.

Spinal cord injury (SCI) is a devastating health condition that may lead to permanent disabilities and death. Understanding the pathophysiological perspectives of traumatic SCI is essential to define mechanisms that can help in designing recovery strategies. Since central nervous system tissues are notorious for their deficient ability to heal, efforts have been made to identify solutions to aid in restoration of the spinal cord tissues and thus its function. The two main approaches proposed to address this issue are neuroprotection and neuro-regeneration. Neuroprotection involves administering drugs to restore the injured microenvironment to normal after SCI. As for the neuro-regeneration approach, it focuses on axonal sprouting for functional recovery of the injured neural tissues and damaged axons. Despite the progress made in the field, neural regeneration treatment after SCI is still unsatisfactory owing to the disorganized way of axonal growth and extension. Nanomedicine and tissue engineering are considered promising therapeutic approaches that enhance axonal growth and directionality through implanting or injecting of the biomaterial scaffolds. One of these recent approaches is nanofibrous scaffolds that are used to provide physical support to maintain directional axonal growth in the lesion site. Furthermore, these preferable tissue-engineered substrates can afford axonal regeneration by mimicking the extracellular matrix of the neural tissues in terms of biological, chemical, and architectural characteristics. In this review, we discuss the regenerative approach using nanofibrous scaffolds with a focus on their fabrication methods and their properties that define their functionality performed to heal the neural tissue efficiently.
