Digital technologies have greatly developed and impacted several aspects of life, including health and lifestyle. Activity tracking, mobile applications, and devices may also provide messages and goals to motivate adopting healthy behaviors, namely physical activity and dietary changes. This review aimed to assess the effectiveness of digital resources in supporting behavior changes, and thus influencing weight loss, in people with overweight or obesity. A systematic review was conducted according to the PRISMA guidelines. The protocol was registered in PROSPERO (CRD42023403364). Randomized Controlled Trials published from the database’s inception to 8 November 2023 and focused on digital-based technologies aimed at increasing physical activity for the purpose of weight loss, with or without changes in diet, were considered eligible. In total, 1762 studies were retrieved and 31 met the inclusion criteria. Although they differed in the type of technology used and in their design, two-thirds of the studies reported significantly greater weight loss among electronic device users than controls. Many of these studies reported tailored or specialist-guided interventions. The use of digital technologies may be useful to support weight-loss interventions for people with overweight or obesity. Personalized feedback can increase the effectiveness of new technologies in motivating behavior changes.

Formaldehyde is a toxic and carcinogenic compound, still used in several occupational settings due to its properties. Thus, in these working scenarios, it is necessary to provide effective measures to reduce workers’ exposure to formaldehyde. The aim of this systematic review is to provide a picture of the worldwide mitigation strategies implemented in occupational environments for minimizing the exposure to formaldehyde and which ones are the most effective for this purpose.The systematic review was performed according to PRISMA statement; the protocol was registered in PROSPERO (CRD42022302207). The search was performed on three electronic databases (PubMed, Scopus, and Web of Science). Studies were considered eligible if they describe strategies for mitigating formaldehyde occupational exposure and their efficacy. We included articles reporting observational studies, semi-experimental, and experimental studies and published in the English language, from the inception to March 26th, 2023. The quality assessment was performed using the Newcastle–Ottawa Quality Assessment Scale.In total, 28 articles were included in the review. The employment scenarios/activities studied were human and veterinary anatomy, autopsy, histopathology or pathology laboratories, embalming procedures, hospital, operating theaters, aquaculture, textile or foundry industries, industry using 3-D printers, offices, and firefighters’ activities. Different methods have proven useful in mitigating formaldehyde exposure, such as the use of personal protective equipment, engineering control methods, organization methods, and technical strategies, with a reduction of airborne formaldehyde until to 99.6%. The highest reduction was obtained in an anatomy laboratory through locally exhausted dissection tables equipped with activated carbon filters.The specific suitable procedures should be standardized and applied in all work settings for an appropriate risk management, in order to protect the health of exposed workers.

Unfortunately, in processing the data of articles included in the originally published review paper, the authors made a mistake and incorrectly indicated an 80.9% reduction in formaldehyde. This is found at the end of the second paragraph in section 'Main characteristics of the studies performed in healthcare and research settings.' In Table 2, the data in the 10th row, under 'Author Year', 'Pre-mitigation value', 'Post-mitigation value', and 'Reduction %' columns were updated to reflect the correct value.
