Travel regions are not necessarily defined by political or administrative boundaries. For example, in the Schengen region of Europe, tourists can travel freely across borders irrespective of national borders. Identifying transboundary travel regions is an interesting problem which we aim to solve using mobility analysis of Twitter users. Our proposed solution comprises collecting geotagged tweets, combining them into trajectories and, thus, mining thousands of trips undertaken by twitter users. After aggregating these trips into a mobility graph, we apply a community detection algorithm to find coherent regions throughout the world. The discovered regions provide insights into international travel and can reveal both domestic and transnational travel regions.

The association of travel distance and other patient characteristics with breast cancer stage at diagnosis and treatment completion at a rural Rwandan cancer facility.

Brigham and Women's Hospital, 75 Francis Street, Boston, MA, 02115, USA.
Background: Butaro Cancer Center of Excellence (BCCOE) was founded to serve Rwanda's rural low-income population, providing subsidized cancer diagnosis and treatment with transport stipends for the lowest-income patients. We examined whether travel distance to BCCOE was associated with advanced-stage diagnoses and treatment completion.
Methods: We conducted a retrospective cohort study using medical record data from BCCOE patients with pathologically-confirmed breast cancer from 2012-2016.
The Efforts to Implement a Malaria Elimination Strategy in The Highly Endemic Malaria Region of Papua Province, Indonesia.

In 2023, Indonesia's Ministry of Health reported that nearly 75% of districts and cities in the country were free from malaria transmission, meaning 90% of the population lived in malaria-free zones. However, Papua Province, which accounts for only 1.5% of Indonesia's population, continues to contribute over 90% of the national malaria cases, with more than 16,000 reported cases in 2023.

Objectives Although childhood cancer treatment has recently become centralized at specialized hospitals worldwide, the relationship between mortality ratios and living in rural areas or traveling long distances for treatment remains controversial. In the present study, we examined whether regional differences in patient mobility and mortality ratios exist in Japan.Methods We investigated 10,713 patients with cancer aged ≤18 years, diagnosed between 2016 and 2019, registered in the national cancer registry data.

Background: Pneumococcal conjugate vaccines (PCVs) introduced in childhood national immunization programs lowered vaccine-type invasive pneumococcal disease (IPD), but replacement with non-vaccine-types persisted throughout the PCV10/13 follow-up period. We assessed PCV10/13 impact on pneumococcal meningitis incidence globally.
Methods: The number of cases with serotyped pneumococci detected in cerebrospinal fluid and population denominators were obtained from surveillance sites globally.

Introduction: The coronavirus disease 2019 (COVID-19) pandemic has significantly impacted public transportation systems worldwide. In this study, we evaluated the rate of COVID-19 positivity and its associated factors among users of public transportation in socioeconomically disadvantaged regions of Brazil during the pre-vaccination phase of the pandemic.
Methodology: This ecological study, conducted in Aracaju city in Northeast Brazil, is a component of the TestAju Program.
