Spin-orbit microlaser emitting in a four-dimensional Hilbert space.

A step towards the next generation of high-capacity, noise-resilient communication and computing technologies is a substantial increase in the dimensionality of information space and the synthesis of superposition states on an N-dimensional (N > 2) Hilbert space featuring exotic group symmetries. Despite the rapid development of photonic devices and systems, on-chip information technologies are mostly limited to two-level systems owing to the lack of sufficient reconfigurability to satisfy the stringent requirement for 2(N - 1) degrees of freedom, intrinsically associated with the increase of synthetic dimensionalities. Even with extensive efforts dedicated to recently emerged vector lasers and microcavities for the expansion of dimensionalities1-10, it still remains a challenge to actively tune the diversified, high-dimensional superposition states of light on demand. Here we demonstrate a hyperdimensional, spin-orbit microlaser for chip-scale flexible generation and manipulation of arbitrary four-level states. Two microcavities coupled through a non-Hermitian synthetic gauge field are designed to emit spin-orbit-coupled states of light with six degrees of freedom. The vectorial state of the emitted laser beam in free space can be mapped on a Bloch hypersphere defining an SU(4) symmetry, demonstrating dynamical generation and reconfiguration of high-dimensional superposition states with high fidelity.

Enabling multiple intercavity polariton coherences by adding quantum confinement to cavity molecular polaritons.

In this study, the "particle in a box" idea, which was broadly developed in semiconductor quantum dot research, was extended into mid-infrared (IR) cavity modes by applying lateral confinement in an optical cavity. The discrete cavity modes hybridized with molecular vibrational modes, resulting in a quartet of polariton states that can support multiple coherence states in the IR regime. We applied tailored pump pulse sequences to selectively prepare these coherences and verified the multi-coherence existence. The simulation based on Lindblad equation showed that because the quartet of polariton states resided in the same cavity, they were specifically robust toward decoherence caused by fluctuations in space. The multiple robust coherences paved the way for entangled states and coherent interactions between cavity polaritons, which would be critical for advancing polariton-based quantum information technology.

Optimizing the data in direct access testing: information technology to support an emerging care model.

Direct access testing (DAT) is an emerging care model that provides on-demand laboratory services for certain preventative, diagnostic, and monitoring indications. Unlike conventional testing models where health care providers order tests and where sample collection is performed onsite at the clinic or laboratory, most interactions between DAT consumers and the laboratory are virtual. Tests are ordered and results delivered online, and specimens are frequently self-collected at home with virtual support. Thus, DAT depends on high-quality information technology (IT) tools and optimized data utilization to a greater degree than conventional laboratory testing. This review critically discusses the United States DAT landscape in relation to IT to highlight digital challenges and opportunities for consumers, health care systems, providers, and laboratories. DAT offers consumers increased autonomy over the testing experience, cost, and data sharing, but the current capacity to integrate DAT as a care option into the conventional patient-provider model is lacking and will require innovative approaches to accommodate. Likewise, both consumers and health care providers need transparent information about the quality of DAT laboratories and clinical decision support to optimize appropriate use of DAT as a part of comprehensive care. Interoperability barriers will require intentional approaches to integrating DAT-derived data into the electronic health records of health systems nationally. This includes ensuring the laboratory results are appropriately captured for downstream data analytic pipelines that are used to satisfy population health and research needs. Despite the data- and IT-related challenges for widespread incorporation of DAT into routine health care, DAT has the potential to improve health equity by providing versatile, discreet, and affordable testing options for patients who have been marginalized by the current limitations of health care delivery in the United States.

Information technology-supported integrated health service for older adults in long-term care settings.

BACKGROUND: To examine the effectiveness and safety of a data sharing and comprehensive management platform for institutionalized older patients. METHODS: We applied information technology-supported integrated health service platform to patients who live at long-term care hospitals (LTCHs) and nursing homes (NHs) with cluster randomized controlled study. We enrolled 555 patients aged 65 or older (461 from 7 LTCHs, 94 from 5 NHs). For the intervention group, a tablet-based platform comprising comprehensive geriatric assessment, disease management, potentially inappropriate medication (PIM) management, rehabilitation program, and screening for adverse events and warning alarms were provided for physicians or nurses. The control group was managed with usual care. Co-primary outcomes were (1) control rate of hypertension and diabetes, (2) medication adjustment (PIM prescription rate, proportion of polypharmacy), and (3) combination of potential quality-of-care problems (composite quality indicator) from the interRAI assessment system which assessed after 3-month of intervention. RESULTS: We screened 1119 patients and included 555 patients (control; 289, intervention; 266) for analysis. Patients allocated to the intervention group had better cognitive function and took less medications and PIMs at baseline. The diabetes control rate (OR = 2.61, 95% CI 1.37-4.99, p = 0.0035), discontinuation of PIM (OR = 4.65, 95% CI 2.41-8.97, p < 0.0001), reduction of medication in patients with polypharmacy (OR = 1.98, 95% CI 1.24-3.16, p = 0.0042), and number of PIMs use (ꞵ = - 0.27, p < 0.0001) improved significantly in the intervention group. There was no significant difference in hypertension control rate (OR = 0.54, 95% CI 0.20-1.43, p = 0.2129), proportion of polypharmacy (OR = 1.40, 95% CI 0.75-2.60, p = 0.2863), and improvement of composite quality indicators (ꞵ = 0.03, p = 0.2094). For secondary outcomes, cognitive and motor function, quality of life, and unplanned hospitalization were not different significantly between groups. CONCLUSIONS: The information technology-supported integrated health service effectively reduced PIM use and controlled diabetes among older patients in LTCH or NH without functional decline or increase of healthcare utilization.

What influences trust in and understanding of clinical trials? An analysis of information and communication technology use and online health behavior from the Health Information National Trends Survey.

BACKGROUND: Using information and communication technologies to seek, discuss, and share health-related information influences people's trust and knowledge of several health practices. However, we know little about the associations between individuals' information and communication technology use and their perceptions of trust and knowledge of clinical trials. Examining these associations may lead to the identification of target audiences and channels for developing effective educational interventions and campaigns about clinical trials. METHODS: In this study, we analyzed Health Information National Trends Survey data to document perceptions of clinical trial-related knowledge and trust that were recently added as questions in this annual national survey of US adults. We also examined correlates of these clinical trial perceptions that included sociodemographic factors and individuals' use of information and communication technologies to seek health information, discuss such information with their healthcare providers, and share the information in their network. RESULTS: More than 90% of participants had no or limited perceived knowledge about clinical trials. Knowledge was higher among those who seek or discuss health-related information online. Differences in perceived knowledge and trust emerged for some racial/ethnic subgroups and other demographic factors. Providers were considered the most trusted source of information (73.6%), followed by health organizations (19.4%) and social support (7.1%). Trust in health organizations compared to health providers was higher among those who used online resources to share health information online with others. Trust in social support was significantly higher among those who used information and communication technologies to communicate about health. CONCLUSION: Based on these findings, we recommend developing online resources about clinical trials to be distributed through social media. These resources should facilitate a dialogue and be targeted to several groups considering their information and communication technologies' use.

Internet interventions and therapies for addressing the negative impact of digital overuse: a focus on digital free tourism and economic sustainability.

BACKGROUND: The excessive use of information technologies (IT) and online digital devices are causing symptoms of burnout, anxiety, stress and dependency that affect the physical and mental health of our society, extending to leisure time and work relationships. Digital free tourism (DFT) is a phenomenon that emerges as a solution to technostress and pathologies derived from digital hyperconnection. The objective of this research is to advance the knowledge of new structures of motivational factors that can understand the decision of a tourist to make a DFT trip. To this end, it is investigated whether family and social engagement and health and relaxation have a positive impact on the behavioral intention of the potential tourist and whether this influences sustainability due to the importance of DFT in the new economic framework. METHODS: With a quantitative approach, the methodology used consisted of an online questionnaire among potential travelers. IBM SPSS Statistics 22.0 statistical software was used to evaluate the data obtained and confirm the relationships of the model and the research hypotheses. RESULTS: The results of the questionnaire assessed the contribution of each construct to the tourist's behavioral intention and the tourist's decision to make the decision to undertake a DFT experience. CONCLUSIONS: DFT can be a driver of economic sustainability and health therapy in tourism in the digital age. This study aims to expand the lines of research on DFT and determine the complex factors that can lead a tourist to participate in the DFT experience. The results obtained can help managers of companies in the sector to offer more efficient and sustainable services that contribute to the health and wellbeing of tourists as a differentiating factor.

Human hand as a powerless and multiplexed infrared light source for information decryption and complex signal generation.

With the increasing pursuit of intelligent systems, the integration of human components into functional systems provides a promising route to the ultimate human-compatible intelligent systems. In this work, we explored the integration of the human hand as the powerless and multiplexed infrared (IR) light source in different functional systems. With the spontaneous IR radiation, the human hand provides a different option as an IR light source. Compared to engineered IR light sources, the human hand brings sustainability with no need of external power and also additional level of controllability to the functional systems. Besides the whole hand, each finger of the hand can also independently provide IR radiation, and the IR radiation from each finger can be selectively diffracted by specific gratings, which helps the hand serve as a multiplexed IR light source. Considering these advantages, we show that the human hand can be integrated into various engineered functional systems. The integration of hand in an encryption/decryption system enables both unclonable and multilevel information encryption/decryption. We also demonstrate the use of the hand in complex signal generation systems and its potential application in sign language recognition, which shows a simplified recognition process with a high level of accuracy and robustness. The use of the human hand as the IR light source provides an alternative sustainable solution that will not only reduce the power used but also help move forward the effort in the integration of human components into functional systems to increase the level of intelligence and achieve ultimate control of these systems.

Improvement of Cancer Prevention and Control: Reflection on the Role of Emerging Information Technologies.

Cancer has become an important public health problem affecting the health of Chinese residents, as well as residents all over the world. With the improvement of cancer prevention and treatment, the growth of the mortality rate of cancers has slowed down gradually, but the incidence rate is still increasing rapidly, and cancers still impose heavy disease and economic burdens. Cancer screening and early cancer diagnosis and treatment are important ways to reduce the burden of cancer-related diseases. At present, various projects for early cancer diagnosis and treatment have been implemented in China. With the expansion of the coverage of these projects, the problems related to project implementation, operation, and management have emerged gradually. In recent years, emerging information technologies have been applied in the field of health and have facilitated health management and clinical decision-making. Meanwhile, China announced multiple policies to encourage and promote the application of information technologies in the field of health. Therefore, combined with the analysis of major problems in cancer prevention and control projects, this paper probes into how to apply information technologies such as biological information mining, artificial intelligence, and electronic information collection technology to various stages of cancer prevention and control. Information technologies realize the integrated management of prevention and control processes, for example, mobilization and preliminary identification, high-risk assessment, clinical screening, clinical diagnosis and treatment, tracking and follow-up, and biological sample management of high-risk groups, and promote the efficient implementation of cancer prevention and control projects in China.

Clinical practice guidelines for telesurgery 2022 : Committee for the promotion of remote surgery implementation, Japan Surgical Society.

Telesurgery is expected to improve medical access in areas with limited resources, facilitate the rapid dissemination of new surgical procedures, and advance surgical education. While previously hindered by communication delays and costs, recent advancements in information technology and the emergence of new surgical robots have created an environment conducive to societal implementation. In Japan, the legal framework established in 2019 allows for remote surgical support under the supervision of an actual surgeon. The Japan Surgical Society led a collaborative effort, involving various stakeholders, to conduct social verification experiments using telesurgery, resulting in the development of a Japanese version of the "Telesurgery Guidelines" in June 2022. These guidelines outline requirements for medical teams, communication environments, robotic systems, and security measures for communication lines, as well as responsibility allocation, cost burden, and the handling of adverse events during telesurgery. In addition, they address telementoring and full telesurgery. The guidelines are expected to be revised as needed, based on the utilization of telesurgery, advancements in surgical robots, and improvements in information technology.

Competencies required to make use of Information Science and Technology among Japanese medical students: a cross-sectional study.

BACKGROUND: Competency in the use of information science and technology (IST) is essential for medical students. This study identified learning objectives and competencies that correspond with low self-assessment related to use of IST and factors that improve such self-assessment among medical students. METHODS: A questionnaire was administered to sixth-year medical students across 82 medical schools in Japan between November 2022 and February 2023. RESULTS: Three learning objectives were identified as difficult for the students to achieve: (1) provide an overview of the regulations, laws, and guidelines related to IST in medicine; (2) discuss ethical issues, such as social disparities caused by the digital divide that may arise in the use of IST in medicine; and (3) understand IST related to medical care. Further, problem-based learning, engaging with IST beyond class, and learning approach impacted the students' acquisition of competencies related to IST. Furthermore, it was recognized that the competencies required by medical students may change over the course of an updated medical school curriculum. CONCLUSIONS: It is important for medical students to recognize the significance of learning, establishing active learning methods, and gaining experience in practically applying these competencies.

Wi-AM: Enabling Cross-Domain Gesture Recognition with Commodity Wi-Fi.

RF-based gesture recognition systems outperform computer vision-based systems in terms of user privacy. The integration of Wi-Fi sensing and deep learning has opened new application areas for intelligent multimedia technology. Although promising, existing systems have multiple limitations: (1) they only work well in a fixed domain; (2) when working in a new domain, they require the recollection of a large amount of data. These limitations either lead to a subpar cross-domain performance or require a huge amount of human effort, impeding their widespread adoption in practical scenarios. We propose Wi-AM, a privacy-preserving gesture recognition framework, to address the above limitations. Wi-AM can accurately recognize gestures in a new domain with only one sample. To remove irrelevant disturbances induced by interfering domain factors, we design a multi-domain adversarial scheme to reduce the differences in data distribution between different domains and extract the maximum amount of transferable features related to gestures. Moreover, to quickly adapt to an unseen domain with only a few samples, Wi-AM adopts a meta-learning framework to fine-tune the trained model into a new domain with a one-sample-per-gesture manner while achieving an accurate cross-domain performance. Extensive experiments in a real-world dataset demonstrate that Wi-AM can recognize gestures in an unseen domain with average accuracy of 82.13% and 86.76% for 1 and 3 data samples.

Impact of information technology supported serious leisure gardening on the wellbeing of older adults: The Turntable project.

OBJECTIVE: The study presented in this paper aimed to assess the effect of an Information Technology enabled community gardening program for older adults, developed by an international consortium. METHODS: We have executed a quantitative, pre- and post-test field trial with older adult volunteers to test the proposed programme in two European countries, Italy and Belgium (n=98). We used standardized and ad hoc questionnaires to measure changes in the volunteers' mental and psychological state during the trial. The statistical data analysis sought for differences in the pre- and post-test values of the key scores related to the perceived quality of life and benefits of gardening via paired-samples t-tests, and also tried to identify the important factors of significant changes via logistic regression. RESULTS: We found significant improvements in the perceived benefits of gardening and also in the scores computed from the WHO Quality of Life instruments, especially in the social sub-domains. The improvements were associated with the country, age, marital state and education of the volunteers. Higher age or being widow, divorced or single increased the odds of a significant improvement in the scores in more than one sub-domains. CONCLUSION: Though the two trial settings were different in some aspects, the observed significant improvements generally confirmed the positive effects of gardening concerning the perceived quality of life and benefits of gardening.

Diagnosis, knowledge, perception, and productivity impact of headache education and clinical evaluation program in the workplace at an information technology company of more than 70,000 employees.

BACKGROUND: Migraine is a highly prevalent, disabling, misunderstood, underdiagnosed, and undertreated neurological disease. It is a leading cause of productivity loss in the workplace. METHODS: This is the first large-scale company-wide headache education and evaluation program in the workplace. RESULTS: 73,432 (90.5%) Fujitsu employees participated. The prevalence of migraine was 16.7%, tension-type headache 40.7%, and cluster headache 0.5%. After completing the training, 82.9% of participants without headache said they would change their attitude towards colleagues with headache disorders and 72.5% of total participants said their understanding of headache changed. The proportion of employees who thought that headache had a significant impact on people's lives increased from 46.8% to 70.6%; 2971 (4.1%) of all participants were interested in a virtual consultation with a headache specialist as part of the program, more than half of whom had not previously consulted for headache. Approximately 14.7 days per year of full productivity per employee with headache were gained resulting in an annual productivity saving per employee of US$4531. CONCLUSION: This unique headache workplace program was associated with a high level of participation, an improvement in the understanding of migraine and attitude towards colleagues with migraine, reduction in disability and increased employee productivity, and decreased costs of lost productivity due to migraine. Workplace programs for migraine should be considered for all industry sectors.

Information technology improves the quality of transfusion practice in China.

BACKGROUND AND OBJECTIVES: Transfusion services in China must establish a quality management system, and regular inspection of quality indicators is an important component of quality management. Although the positive role of information technology in reducing human errors has been widely reported, its role in improving transfusion quality indicators still requires further study. This study explores the role of information technology in improving the quality of transfusion practice. MATERIALS AND METHODS: We developed an optimized blood transfusion management information system and then analysed the changes in four quality indicators before and after using the system to clarify the role of information technology in improving the quality of transfusion practice. RESULTS: After using the optimized system, the completeness rate for transfusion request forms increased from 81.5% to 99.3%; an unqualified doctor's signature was the most common incomplete content (0.45%). The appropriate transfusion rate increased from 87% to 99.4%, and red blood cell and frozen plasma utilization in most surgical departments decreased. Although the reporting rate for adverse transfusion reactions increased from 0.22% to 0.49%, these increases might be partly due to changes in transfusion regulations. The adequacy rate of transfusion medical records increased from 74.8% to 90.4%. Overall, the inadequacy of informed consent for transfusion, pre-transfusion laboratory tests and documentation of the transfusion process were reduced from 6.4%, 6.2% and 12.6% to 1.7%, 2.0% and 5.9%, respectively. CONCLUSION: Information technology can play an important role in improving the quality of transfusion practice, as part of a programme of medical education, regular audit and other measures.

Effects of work-related electronic communication during non-working hours after work from home and office on fatigue, psychomotor vigilance performance and actigraphic sleep: observational study on information technology workers.

OBJECTIVES: This study examined the effects of work-related electronic communication (WREC) during non-working hours in the work from home or office setting on health. METHODS: The study recruited 98 information technology workers in a 9-day observational study. They recorded work-life events (eg, work style (working mostly from home or the office) and duration of WREC during non-working hours) and subjective ratings (eg, current fatigue, sleepiness and depression) and wore a sleep actigraph to measure objective sleep variables before bedtime every day. They completed the Brief Psychomotor Vigilance Test (PVT-B) before bedtime for 4 days. RESULTS: The frequency of WREC was significantly higher when working mostly from home than in the office (p<0.01). In addition, the duration of WREC was longer when working mostly from home than in the office (p<0.001). Linear or generalised linear mixed model analysis for fatigue, depression and PVT lapse revealed significant interaction effects between work style and WREC (all p<0.05). Post hoc analysis showed that the longer the WREC, the worse the fatigue and depression and the lower the lapse on working mostly from the office (all p<0.05). CONCLUSIONS: Longer WREC is associated with worse fatigue and depression and lower lapse of PVT (higher alertness) before bedtime for working mostly from the office. Workers, especially those working from the office, should minimise WREC during non-working hours to maintain good health. Therefore, companies, managers and other relevant stakeholders should refrain from contacting workers during non-working hours.

Costing analysis of an information & communications technology-enabled primary healthcare facility in India.

BACKGROUND & OBJECTIVES: Information and communications technology (ICT) has often been endorsed as an effective tool to improve primary healthcare. However, evidence on the cost of ICT-enabled primary health centre (PHC) is lacking. The present study aimed at estimating the costs for customization and implementation of an integrated health information system for primary healthcare at a public sector urban primary healthcare facility in Chandigarh. METHODS: We undertook economic costing of an ICT-enabled PHC based on health system perspective and bottom-up costing. All the resources used for the provision of ICT-enabled PHC, capital and recurrent, were identified, measured and valued. The capital items were annualized over their estimated life using a discount rate of 3 per cent. A sensitivity analysis was undertaken to assess the effect of parameter uncertainties. Finally, we assessed the cost of scaling up ICT-enabled PHC at the state level. RESULTS: The estimated overall annual cost of delivering health services through PHC in the public sector was ₹ 7.88 million. The additional economic cost of ICT was ₹ 1.39 million i.e. 17.7 per cent over and above a non-ICT PHC cost. In a PHC with ICT, the cost per capita increased by ₹ 56. On scaling up to the state level (with 400 PHCs), the economic cost of ICT was estimated to be ₹ 0.47 million per year per PHC, which equates to approximately six per cent expenditure over and above the economic cost of a regular PHC. INTERPRETATION & CONCLUSIONS: Implementing a model of information technology-PHC in a state of India would require an augmentation of cost by about six per cent, which seems fiscally sustainable. However, contextual factors related to the availability of infrastructure, human resources and medical supplies for delivering quality PHC services will also need to be considered.

The preferred IT sources and tools of Iranian people for accessing health information.

INTRODUCTION: People need health information to maintain their health. Despite the variety of sources and tools for providing health information, there is little evidence about Iranian people's preferences in using these sources and tools. The objective of this study was to identify the preferred health information sources, tools, and methods for presenting health information in these tools. METHODS: This national survey was conducted among a sample of 4000 Iranian people between April and September 2021. The data was collected using a valid and reliable questionnaire (α = 0.86) consisting of four sections: participants' demographic information, current sources of obtaining health information, preferred information technology (IT) tools for accessing health information, and the method of presenting this information. Linear regression was used to investigate the relationship between demographic factors and other questions. RESULTS: The participants received health information mostly from the "Internet" (3.62), "family or friends" (3.43), "social networks" (3.41), "specific websites" (3.41), and "mobile apps" (3.27). "Social networks" (3.67), Internet "websites" (3.56), and "mobile apps" (3.50) were the most suitable tools for receiving health information. The participants preferred the presentation of health information in the form of "Images" (3.85), "educational videos" (3.69), and "texts" (3.53). Age, education, and marital status had a significant relationship with most of the preferred information sources, tools, and information presentation methods (p < 0.05). CONCLUSION: The results of this study showed that Iranian people are more active information seekers than passive ones compared to a decade ago. The preferred sources and tools identified in this research can be used by healthcare planners and policy-makers in Iran and other developing countries to design and develop IT interventions that meet people's needs. Improving access to the Internet, social networks, and mobile apps and providing health information via images, educational videos, and texts on these platforms enhance access to the information people need.

Beliefs about medications when treating hypertension in primary health care: results from "PERson-centredness in hypertension management using information Technology (PERHIT)".

PURPOSE: Hypertension is a major global health concern. Despite of efficient antihypertensive medications a low percentage of patients reach a blood pressure (BP) of <140/90. Nonadherence is a great concern in hypertension treatment and patients' beliefs about medications has been shown to have a strong impact on adherence. The objective of this study is to examine beliefs about medications and its impact on BP treatment in a group of Swedish primary healthcare patients treated for hypertension with or without an E-health platform. MATERIALS AND METHOD: In a randomised unblinded controlled trial, 949 patients with hypertension from Swedish primary health care centres were included. The intervention group used a web-based system to support self-management of hypertension for eight weeks. Beliefs about medication questionnaire (BMQ) were administered to all patients at inclusion, 8-week follow up and 1-year follow up. RESULTS: Data were collected from the 862 patients who completed the trial. No statistically significant difference was found in BMQ-scores between the intervention and the control group. An association between lower scores in the BMQ subsection 'General-Harm' and achieving target BP of <140/90 mmHg were noted (p = 0.021). CONCLUSION: This study shows a significant association between beliefs about medication and BP levels, on hypertensive patients in the Swedish primary care setting, in only one out of four subsections of the BMQ. The intervention did not have a significant effect on changing patients' beliefs about medication. Further emphasis on patients' beliefs about medications could be useful in the clinical setting.

What is the context? Insufficient treatment effect of high blood pressure is a major global health concern, even though there are several different effective medications. Patients not taking their medications, as they have been prescribed, is a well-known contributing factor. There are associations between underlying beliefs about medications and how strict patients adhere to their prescriptions.What is new? In this study data was collected from 862 patients with high blood pressure. The participants were randomised into two groups, one group got treatment as usual and the other group used a web-based interactive information technology system for 8 weeks, in addition to their medications. All participants answered questionnaires about their beliefs about medications. It was shown that the beliefs about medications had limited significant associations to blood pressure levels. Furthermore, the intervention seemed to have no effect upon patients' beliefs about medications.What is the impact? This study provides further evidence that patients' beliefs about medications might be a possible factor to take into consideration when aiming to treat high blood pressure. The intervention used in this study had no impact on patients' beliefs about medications.
