Assessment of the impact of Uber system implementation on mortality from traffic injuries in Brazilian capital cities.

The rapid expansion of Uber Technologies, Inc.'s ride-sharing, courier service, and food delivery system and e-hailing applications has been transforming the logistics network and urban mobility around the world. We aimed to evaluate the impact of the Uber system on traffic injury (TI) mortality during its implementation in Brazilian capital cities.

Dengue, chikungunya, and Zika virus infections in Latin America and the Caribbean: a systematic review.

Objectives: To characterize the distribution profile of dengue, chikungunya, and Zika virus infections in Latin America and the Caribbean and to identify possible factors associated with the risk of dissemination and severity of these arboviruses.

Methods: The protocol of this review was registered on the PROSPERO platform. Searches were carried out in the following databases: Virtual Health Library, MEDLINE/PubMed, and Embase.

Mortality trend from falls in Brazilian older adults from 2000 to 2019.

Objective: To analyze the trend of mortality from falls among older adults in Brazil from 2000 to 2019.

Methods: This is an epidemiological, analytical study with an ecological time-series design. A retrospective analysis was performed using secondary health data extracted from the Brazilian Mortality Information System in the specific period.

[High-risk clusters and temporal trends in congenital syphilis infection in Brazil].

Objective: To determine the occurrence of high-risk clusters for congenital syphilis (CS) in Brazil and describe the temporal trends in the CS infection in the country, comparing children whose mothers received vs. those whose mothers did not receive prenatal care.

Method: This ecological study used data from the National Disease Notification System (, SINAN) and the Live Birth Information System (, SINASC).

Bacterial vaginosis, representation of endocervical and/or metaplastic cells, and cytological abnormalities in different age groups: Association study.

Background: Studies have indicated that bacterial vaginosis (BV) might be a cofactor for the acquisition and persistence of high-risk papillomavirus, enabling the development of cytological abnormalities. The presence of endocervical and metaplastic cells makes the smear more adequate for the detection of these abnormalities once these cell types are representative of the transformation zone, a site of increased susceptibility to viral infection.

Methods: The purpose of this study was to evaluate the patterns of vaginal microbiota, the representation of endocervical and/or metaplastic cells, and the detection of cytological abnormalities in cervical smears from women 15 to 64 years old.
