Convenience, privacy, and cost-effectiveness associated with web-based data collection has facilitated the recent expansion of online survey research. Importantly, however, practical benefits of online survey research, to scientists and participants alike, are being overshadowed by the dramatic rise in suspicious and fraudulent online survey submissions. Misinformation associated with online survey fraud compromises data quality and data integrity with important implications for scientific conclusions, clinical practice, and social benefit. Transparency in reporting on methods used to prevent and manage suspicious and fraudulent submissions is key to protecting the veracity of online survey data; yet there is limited discussion on the use of anti-deception strategies during all phases of survey research to detect and eliminate low-quality and fraudulent responses.

Prisoner health is a major global concern, with prisoners often facing limited access to healthcare and suffering from chronic diseases, infectious diseases, and poor mental health due to unsafe prison environments, unhygienic living conditions, and inadequate medical resources. In Taiwan, prison health is an increasing issue, particularly concerning urinary diseases such as urinary tract infections (UTIs). Limited access to healthcare and unsanitary conditions exacerbate these problems. Urinary disease epidemiology varies by sex and age, yet, studies in Asia are scarce, and comprehensive data on urinary diseases in Taiwanese prisons remain limited.

In March 2022, a concerning rise in cases of unexplained paediatric hepatitis was reported in multiple countries. Cases were defined as acute hepatitis with serum transaminases >500 U/L (aspartate transaminase (AST) or alanine transaminase (ALT)) in children aged 16 or under. We explored a simple federated data analytics method to search for evidence of unreported cases using routinely held data. We conducted a pragmatic survey to analyse changes in the proportion of hospitalised children with elevated AST or ALT over time. In addition, we studied the feasibility of using routinely collected clinical laboratory results to detect or follow up an outbreak of an infectious disease.

Oral health significantly influences overall well-being, health care costs, and quality of life. In Saudi Arabia, the burden of oral diseases, such as dental caries and periodontal disease, has increased over recent decades, driven by various lifestyle changes.

In-flight medical emergencies (IMEs) might cause severe outcomes, including the deaths of passengers and aircraft diversion. Information is lacking regarding the incidence and characteristics of IMEs in most countries, especially in mainland China.

Despite high prevalence of chronic hepatitis B virus (HBV) infection in adults in Lao People’s Democratic Republic (PDR), Lao healthcare workers (HCWs) were previously been shown to have low levels of protection against infection. Furthermore, the prevalence of hepatitis D virus (HDV; which increases disease severity in HBV infected individuals) is not known in Lao PDR.

Hand, foot, and mouth disease (HFMD) is a highly contagious viral illness. Understanding the long-term trends of HFMD incidence and the epidemic characteristics under the circumstances of the vaccination program and the outbreak of the novel coronavirus disease is crucial for effective disease surveillance and control.

The rapid rise of myopia worldwide, particularly in East and Southeast Asia, has implied environmental influences beyond genetics. To address this growing public health concern, the World Health Organization and International Telecommunication Union launched the MyopiaEd program. South Korea, with its high rates of myopia and smartphone use, presented a suitable context for implementing and evaluating the MyopiaEd program.

China is a country with a high burden of hepatitis B (Hep B) but a low treatment rate. One of the key reasons for the low treatment rate is inadequate health literacy (HL) of the people, which may affect the awareness and knowledge of Hep B and the treatment, as well as the ability to actively and correctly seek medical resources.

Unobtrusive observation is a promising method for assessing physical activity and other well-being behaviors (eg, social interactions) in urban environments, without participant burden and biases associated with self-report. However, current methods require multiple in-person observers. Using video cameras instead could allow for more accurate observations at lower cost and with greater flexibility in scheduling.

Recently, the phase angle (PhA) emerged as an essential indicator of cellular health. Most studies examined its association with physiological conditions, such as sarcopenia, frailty, and physical function in older populations. Simultaneously, growing attention is being paid to the clinical relevance of segmental PhA for future applications. However, few studies explored the relationship between PhA, especially segmental PhA, and the psychological aspects of health, particularly cognitive function.

COVID-19 has not only resulted in acute health issues but also led to persistent symptoms known as long COVID, which have been linked to disruptions in sleep quality.
