Telepathology, as a subset of teleconsulting, is pathology interpretation performed at a distance. Telepathology is not a new phenomenon, but since ~2015, significant advances in information technology and telecommunications coupled with the pandemic have led to unprecedented sophistication, accessibility, and use of telepathology in human and veterinary medicine. Furthermore, telepathology can connect veterinary practices to distant laboratories and provide support for underserved animals and communities. Through our scoping review, we provide an overview of how telepathology is being used in veterinary medicine, identify gaps in the literature, and highlight future areas of research and service development. We searched MEDLINE, CAB Abstracts, and the gray literature, and included all relevant literature. Despite the widespread use of digital microscopy in large veterinary diagnostic laboratories, we identified a paucity of literature describing the use of telepathology in veterinary medicine, with a significant gap in studies addressing the validation of whole-slide imaging for primary diagnosis. Underutilization of telepathology to support postmortem examinations conducted in the field was also identified, which indicates a potential area for service development. The use of telepathology is increasing in veterinary medicine, and pathologists must keep pace with the changing technology, ensure the validation of innovative technologies, and identify novel uses to advance the profession.

It has been proposed to implement the >100 Gb/s data-center interconnects using a two-channel optical time-division multiplexed system with multilevel pulse-amplitude modulation. Unlike the conventional four-channel optical time-division multiplexed system which requires an expensive narrow pulse, the two-channel system can be implemented cost-effectively using a wide pulse (which can be simply generated using a single modulator). The two-channel system is expected to be practically available using an integrated transmitter in a chip due to the recent advances in photonics-integrated circuits. This paper reviews the current stage of research on a two-channel optical time-division multiplexed system and discusses possible research directions. Furthermore, it has been demonstrated that 200 Gb/s signals can be generated by using modulators with only 17.2 GHz bandwidth. Therefore, the use of the phase-alternating pulse can make the multiplexed signal robust to chromatic dispersion, enabling the 200 Gb/s 4-level pulse-amplitude-modulated signal to be transmitted over 1.9 km of standard single-mode fiber.

BACKGROUND: The availability of low-cost computing and digital telecommunication in the 1980s made telehealth practicable. Telehealth has the capacity to improve healthcare access and outcomes for patients while reducing healthcare costs across a wide range of health conditions and situations.
OBJECTIVE: This study compares the adoption, advantages, and challenges of telehealth services between high-income (HICs) and low-and-middle-income countries (LMICs) before and during the COVID-19 pandemic.
METHODS: Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines were followed. The key search terms were: \"Telehealth\", \"Telehealth in HICs\", \"Telehealth in LMICs\", \"Telehealth before COVID-19\", \"Telehealth during COVID-19\". We searched exhaustively ProQuest, Scopus, Web of Science, Google Scholar, CINAHL, and EMBASE databases from 2012. Booleans OR/AND were combined with key search terms to increase relevant search results. The literature search and selection process followed the Sample, Phenomena of Interest, Design, Evaluation, and Research (SPIDER) question format.
RESULTS: The adoption of telehealth before COVID-19 was generally low in both HICs and LMICs. The impact of COVID-19 accelerated the adoption of telehealth at the facility level but not nationwide in both high-income countries and LMICs. The rapid adoption of telehealth at the facility level in both high-income and LMICs introduced several challenges that are unique to each country and need to be addressed.
CONCLUSIONS: The lack of national policies and regulations is making the adoption of telehealth at the national level challenging in both high and low-middle-income countries. Governments and Stakeholders of healthcare must consider telehealth as a healthcare procedure that should be deployed in clinical working procedures. Primary quantitative and qualitative studies must be conducted to address challenges encountered during the pilot implementation of telehealth services in both high-income countries and LMICs before and during pandemics.

Telemedicine has become more convenient and advantageous due to the rapid development of the internet and telecommunications. A growing number of patients are turning to telemedicine for health consultations and health-related information. Telemedicine can increase access to medical care by removing geographical and other barriers. In most nations, the COVID-19 pandemic imposed social isolation. This has accelerated the transition to telemedicine, which has become the most commonly utilized method of outpatient care in many places. Telehealth can assist resolve gaps in access to healthcare services and health outcomes, in addition to its primary function of boosting accessibility to remote health services. However, as the benefits of telemedicine become more apparent, so do the limitations of serving vulnerable groups. Some populations may lack digital literacy or internet access. Homeless persons, the elderly, and people with inadequate language skills are also affected. In such circumstances, telemedicine has the potential to exacerbate health inequities.
In this narrative review (using the PubMed and Google scholar database), the different benefits and drawbacks of telemedicine are discussed, both globally and in Israel, with particular focus paid to special populations and to the telehealth usage during the Covid-19 period.
The contradiction and paradox of using telemedicine to address health inequities yet sometimes making them worse is highlighted. The effectiveness of telemedicine in bridging access to healthcare inequities is explored along with a number of potential solutions.
Policy makers should identify barriers among special populations to using telemedicine. They should initiate interventions to overcome these barriers, while adapting them to the needs of these groups.

There is a lack of research on the specific experiences and needs of geographically distant kin caregivers in end-of-life situations. Clinicians and researchers would benefit from a systematic overview. The scoping review aimed at examining the international literature on the experiences and needs of informal long-distance (LD) caregivers at the end of life, to address gaps in the evidence base, and to make recommendations for further research.
The scoping review was conducted according to the methodological framework of Arksey and O\'Malley. Studies of various designs involving kin caregivers were analysed narratively.
A highly sensitive strategy was used to search CINAHL, Google Scholar, PsycInfo, PubMed and Web of Science Core Collection, from inception to 8 November 2021, with searches rerun in CINAHL, PsycInfo and PubMed on 31 January 2023. An additional hand search of the reference lists of the identified articles was performed.
Two authors independently assessed the titles and abstracts of 3827 scientific papers. As a result, 89 full texts were reviewed and 20 articles plus one review were included in the review. Five major themes were identified: (1) LD as a barrier to caregiving, (2) communication difficulties and the role of video and telephone calls, (3) the burdens and benefits of LD caregiving, (4) interaction and conflict with local caregivers and (5) LD caregivers\' wishes and needs for support.
Further quantitative and mixed-methods studies should be undertaken to improve our understanding of LD caregiving for relatives at the end of life. Studies to explore the feasibility and implementation of communication technologies in end-of-life LD caregiving are also needed.

Currently, acupressure is widely accepted as a non-pharmacological therapy for managing pain, nausea and vomiting, and mental health conditions. Since acupressure can be self-administered, clinicians and researchers\' interest in information and communication technologies (ICTs) for disseminating acupressure to manage symptoms has increased. This mini review was conducted to examine clinical studies of acupressure using ICTs, with a particular focus on self-acupressure. Through a search of MEDLINE, EMBASE, and CENTRAL, all studies of self-acupressure using ICTs published before December 31, 2021 were collected. Twelve studies met the inclusion criteria. More than half of the studies published since 2020 (4/7, 54.14%) were described as being related to COVID-19. As target conditions, musculoskeletal injuries or pain, cancer-related symptoms, dysmenorrhea, mental health issues, and obesity were considered. The most frequently used acupoints were LI4, LR3, and Shenmen. Moreover, smartphone applications were the most commonly used ICT method to support self-acupressure. In addition to the basic information of self-acupressure, other tools such as timers, reminders, and schedule checkers to facilitate its implementations have been incorporated into the smartphone applications. Recently, there have been some attempts to combine acupressure and ICTs. Although these studies mainly focus on musculoskeletal pain or injuries, recent studies related to mental health have emerged in relation to COVID-19. However, few studies have been conducted to date, making it difficult to fully grasp the trends in this field. Therefore, more studies are needed to evaluate the feasibility and efficacy of combining self-acupressure and ICTs in more diverse clinical areas.

OBJECTIVE: To evaluate the effectiveness of telenursing involving nurses on the health outcomes of adults with lung cancer at home.
METHODS: We conducted literature searches on PubMed, CINAHL, EMBASE, CENTRAL, and the Japan Medical Abstracts Society up to December 2021. Articles eligible for inclusion were (i) reporting on randomized controlled trials involving telenursing, (ii) focusing on health consultations provided by healthcare providers involving nurses, and (iii) targeting adults with lung cancer at home. Two researchers independently screened eligible studies and assessed the risk of bias using the Cochrane risk-of-bias tool 2. We performed meta-analyses of symptom distress and quality of life. This study was reported according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses. The quality of evidence was assessed applying the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) approach.
RESULTS: Four studies with 508 participants were included, of which three were finally evaluated by meta-analysis. Telemonitoring and education by nursing professionals in collaboration with other healthcare professionals were confirmed. Symptom distress was significantly lower in the intervention group (mean difference = -0.54, 95% confidence interval: -1.06, -0.02). There was no significant effect on other outcomes. The GRADE assessment revealed serious risk of bias, inconsistency, and imprecision.
CONCLUSIONS: The findings suggest that telenursing brought about low symptom distress in adults with lung cancer compared with the absence of telenursing. However, the certainty of the evidence was low owing to the high risk of bias. Further accumulation of high-quality studies is needed to establish definitive evidence.

Telemedicine (TLM) is a technique of telecommunication used to create, promote, or accelerate health services. Because of its societal significance, the current study attempted to demonstrate its essential applications in the health sector and the challenges, obstacles, and opportunities that lie ahead. Various studies and reports were received based on the subject of the current study, first using MeSH terms related to the subject in authentic and available international databases. After that, 30-related articles were selected based on the study criteria, and then the required results were extracted from the selected studies. The study results showed that TLM has a significant role in more than 13 major areas of health and treatment, and in most of these areas, it has made the relevant affairs easier for both patients and medical staff. Although TLM has many advantages, it still has obstacles and challenges requiring further studies to manage this technology better. Given the high importance of the TLM in the health sector in most countries worldwide, efforts are needed to promote this technology and remove the obstacles in front of it. Therefore, further evaluations of TLM efficiency in terms of economics, speed of action, effectiveness, and the provision of infrastructure are necessary to overcome the obstacles highlighted based on the results of these studies and improve the efficiency of using this technology.
