Background: Eruption of primary teeth is associated with local and systemic manifestations. Understanding the global prevalence is necessary to formulate the standard guidelines for management.
Aim: To evaluate the global prevalence of problems associated with teething in infants and children aged 0-36 months.
Design: PubMed, LILACS, Web of Science, Scopus, and EMBASE were searched on May 31, 2023, and it was updated on January 31, 2024. Gray literature and reference search were performed. Cross-sectional, case-control, and cohort studies done in hospital or community settings, reporting the prevalence of signs and symptoms during the eruption of primary teeth in infants aged 0-36 months, were included. Two reviewers extracted data using a pre-piloted sheet. Data were analyzed and pooled by using random-effects meta-analyses.
Results: Twenty-five studies were included. The global prevalence of teething problems was 80.0% (95% confidence interval [CI]: 67.8-89.9). The most common local symptom was increased biting (65.9%, 95% CI 37.5-89.3), and irritability (60.7%, 95% CI 50.6-70.3) was the most common general symptom.
Conclusion: The pooled prevalence of teething problems was estimated to be 80%. There was a variability in the prevalence of teething problems based on geographic location.

Importance: Comprehensive incidence and prevalence rates of frontotemporal dementia are currently not available.
Objective: To estimate the incidence and prevalence of frontotemporal dementia and its clinical variants in the overall population and age subgroups.
Data Sources And Study Selection: We systematically searched PubMed, EMBASE, and Scopus between January 1, 1990, and October 22, 2024, for population-based studies estimating the incidence and/or prevalence of FTD.

Since the first decentralized clinical trial (DCT) was conducted in 2011, there has been an increased usage of DCT due to its benefits of patient-centricity and generalizability of findings. This trend was further expedited by the global COVID-19 pandemic. We identified 23 case studies across various therapeutic areas and grouped them into different categories according to their purposes-by necessity, for operational benefits, to address unique research questions, to validate innovative digital endpoints, or to validate decentralization as a clinical research platform.

Importance: Previous studies have suggested that social participation helps prevent depression among older adults. However, evidence is lacking about whether the preventive benefits vary among individuals and who would benefit most.
Objective: To examine the sociodemographic, behavioral, and health-related heterogeneity in the association between social participation and depressive symptoms among older adults and to identify the individual characteristics among older adults expected to benefit the most from social participation.
