In recent years, the number of bedridden patients, including amyotrophic lateral sclerosis (ALS) patients, has been increasing with the aging of the population, owing to advances in medical and long-term care technology. Eye movements are physical functions that are relatively difficult to be affected, even if the symptoms of ALS progress. Focusing on this point, in this paper, in order to improve the quality of life (QOL) of bedridden patients, including ALS patients, we propose a drone system connected to the Internet that can be remotely controlled using only their eyes. In order to control the drone by using only their eyes, a control screen and an eye-tracking device were used in this system. By using this system, for example, the patients in New York can operate the drone in Kyoto using only their eyes, enjoy the scenery, and talk with people in Kyoto. In this drone system, since a time delay could occur depending on the Internet usage environment, agile operation is required for remotely controlling the drone. Therefore, we introduce the design of the control screen focused on remote control operability and human eye movements (microsaccades). Furthermore, considering the widespread future use of this system, it is desirable to use a commercial drone. Accordingly, we describe the design of a joystick control device to physically control the joysticks of various drone controllers. Finally, we present experimental results to verify the effectiveness of this system, including the control screen and the joystick control device.

Abstract Objective: Candida auris infections continue to occur across the United States and abroad, and healthcare facilities that care for vulnerable populations must improve their readiness to respond to this emerging organism. We aimed to identify and better understand challenges faced and lessons learned by those healthcare facilities who have experienced C. auris cases and outbreaks to better prepare those who have yet to experience or respond to this pathogen. Design: Semi-structured qualitative interviews. Setting: Health departments, long-term care facilities, acute-care hospitals, and healthcare organizations in New York, Illinois, and California. Participants: Infectious disease physicians and nurses, clinical and environmental services, hospital leadership, hospital epidemiology, infection preventionists, emergency management, and laboratory scientists who had experiences either preparing for or responding to C. auris cases or outbreaks. Methods: In total, 25 interviews were conducted with 84 participants. Interviews were coded using NVivo qualitative coding software by 2 separate researchers. Emergent themes were then iteratively discussed among the research team. Results: Key themes included surveillance and laboratory capacity, inter- and intrafacility communication, infection prevention and control, environmental cleaning and disinfection, clinical management of cases, and media concerns and stigma. Conclusions: Many of the operational challenges noted in this research are not unique to C. auris, and the ways in which we address future outbreaks should be informed by previous experiences and lessons learned, including the recent outbreaks of C. auris in the United States.

Optokinetic nystagmus (OKN) is an involuntary eye movement induced by motion of a large proportion of the visual field. It consists of a “slow phase (SP)” with eye movements in the same direction as the movement of the pattern and a “fast phase (FP)” with saccadic eye movements in the opposite direction. Study of OKN can reveal valuable information in ophthalmology, neurology and psychology. However, the current commercially available high-resolution and research-grade eye tracker is usually expensive. Methods & Results: We developed a novel fast and effective system combined with a low-cost eye tracking device to accurately quantitatively measure OKN eye movement. Conclusions: The experimental results indicate that the proposed method achieves fast and promising results in comparisons with several traditional approaches.

Objective.To describe the control of an outbreak of infection and colonization with the New York/Japan methicillin-resistantStaphylococcus aureus(MRSA) clone in multiple healthcare facilities, and to demonstrate the importance of making an MRSA management policy involving molecular typing of MRSA into a statewide public health responsibility.Setting.A range of healthcare facilities, including 2 metropolitan teaching hospitals and a regional hospital, as well as several community hospitals and long-term care facilities in a nonmetropolitan healthcare region.Interventions.A comprehensive, statewide MRSA epidemiological investigation and management policy.Results.In May 2005, there were 3 isolates referred to the Western Australian Gram-Positive Bacteria Typing and Research Unit that were identified as the New York/Japan MRSA clone, a pandemic MRSA clone with the ability to spread and replace existing clones in a region. Subsequent investigation identified 28 additional cases of infection and/or colonization dating from 2002 onward, including 1 involving a colonized healthcare worker (HCW) who had previously been hospitalized overseas. Of the 31 isolates detected, 25 were linked epidemiologically and via molecular typing to the isolate recovered from the colonized HCW. Four isolates appeared to have been introduced separately from overseas. Although the isolate from the single remaining case patient was genetically indistinct from the isolates that spread within Western Australia, no specific epidemiological link could be established. The application of standard outbreak management strategies reduced further spread.Conclusions.The elimination of the New/York Japan MRSA clone in a healthcare region demonstrates the importance of incorporating MRSA management policy into statewide public health programs. The mainstays of such programs should include a comprehensive and effective outbreak identification and management policy (including pre-employment screening of HCWs, where applicable) and MRSA clone identification by multilocus sequence typing.

BACKGROUND Since the COVID-19 pandemic, telemedicine appointments have replaced many in-person healthcare visits [1 2]. However, older people are less likely to participate in telemedicine, preferring either in-person care or foregoing care altogether [3-6]. With a high prevalence of chronic conditions and vulnerability to COVID-19 morbidity and mortality through exposure to others in health care environments, (1-4), promoting telemedicine use should be a high priority for seniors. Seniors face significant barriers to participation in telemedicine, including lower internet and device access and skills, and visual, auditory, and tactile difficulties with telemedicine. OBJECTIVE Hoping to offer training to increase telemedicine use, we undertook a quality improvement survey to identify barriers to, and facilitators of telemedicine among seniors presenting to an outpatient family medicine teaching clinic which serves predominantly African American, economically disadvantaged adults with chronic illness in Cleveland, Ohio. METHODS Our survey, designated by the IRB as quality improvement, was designed based on a review of the literature, and input from our primary care providers and a digital equity expert (Figure 1). To minimize patient burden, the survey was limited to 10 questions. Because we were interested in technology barriers, data were collected on paper rather than a tablet or computer, with a research assistant available to read the survey questions. Patients presenting with needs that could be accomplished remotely were approached by a research assistant to complete the survey starting February 2021 until we reached the pre-determined sample size (N=30) in June 2021. Patients with known dementia, those who normally resident in a long-term care facility, and those presenting with an acute condition (e.g. fall or COPD exacerbation) were ineligible. Because of the small number of respondents, only univariate and bivariate tabulations were performed, in Excel. RESULTS 83% of respondents said they had devices that could be used for a telemedicine visit and that they went on the internet, but just 23% had had telemedicine visits. Few patients had advanced devices (iPhones, desktops, laptops or tablets); 46% had only a single device that was not IOS based mobile (Table 1). All participants with devices said they used them for “messaging on the internet,” but this was the only function used by 40%. No one used the internet for banking, shopping, and few used internet functions commonly needed for telemedicine (23.3% had email; 30% did video calling) (Table 1). 23.3% of respondents had had a telemedicine appointment. Many reported a loss of connection to their doctor as a concern. Participants who owned a computer or iPhone used their devices for a broader range of tasks, (Table 2 and 3), were aged 65-70 (Table 4), and were more likely to have had a telemedicine visit and to have more favorable views of telemedicine (Table 2). Respondents who had not had a telemedicine appointment endorsed a greater number of telemedicine disadvantages and endorsed less interest in future appointments (Table 2). Respondents who did not own an internet-capable device did not report using any internet functions and none had had a telemedicine appointment (Table 2). CONCLUSIONS This small survey revealed significant gaps in telemedicine readiness among seniors who said they had devices that could be used for telemedicine and that they went online themselves. No patients used key internet functions needed for staying safe during COVID, and few used internet applications that required skills needed for telemedicine. Few patients had devices that are optimal for seniors using telemedicine. Patients with more advanced devices used more internet functions and had more telemedicine experience and more favorable attitudes than others. Our results confirm previous studies [7-9] showing generally lower technological proficiency among older adults and some concerns about participating in telemedicine. However, our study is novel in pointing to subtle dimensions of telemedicine readiness that warrant further study—device capacity and use of internet in ways that build skills needed for telemedicine such as email and video calling. Before training seniors to use telemedicine, it’s important to ensure that they have the devices, basic digital skills and connectivity needed for telemedicine. Larger studies are needed to confirm our results and apply multivariate analysis to understand the relationships among age, device quality, internet skills and telemedicine attitudes. Development of validated scales of telemedicine readiness and telemedicine training to complement in-person care can help health systems offer precision-matched interventions to address barriers, facilitate increased adoption, and generally improve patients’ overall access to primary care and engagement with their primary care provider.

Minerva Tantoco was named New York City’s first chief technology officer last year, charged with developing a coordinated citywide strategy on technology and innovation. We’re likely to see more of that as cities around the country, and around the world, consider how best to use innovation and technology to operate as “smart cities.”The work has major implications for energy use and sustainability, as cities take advantage of available, real-time data – from ‘smart’ phones, computers, traffic monitoring, and even weather patterns — to shift the way in which heating and cooling systems, landscaping, flow of people through cities, and other pieces of urban life are controlled. But harnessing Open Innovation and the Internet of Things can promote sustainability on a much broader and deeper scale. The question is, how do you use all the available data to create a more environmentally sound future? The term “Internet of Things” was coined in 1999 by Kevin Ashton, who at the time was a brand manager trying to find a better way to track inventory. His idea? Put a microchip on the packaging to let stores know what was on the shelves.
