[Statistical literacy and risk communication for COVID-19 vaccination: a scoping reviewLiteracia estatística e comunicação de risco para a vacinação contra a COVID-19: revisão de escopo].

Objective: To describe the role of statistical literacy and proper risk communication in communication strategies related to COVID-19 vaccination.

Methods: A scoping review was carried out in January 2021, with the keywords "statistical literacy," "risk communication," "health communication," and "pandemic," in the Pan American Health Organization Virtual Health Library, PubMed, Web of Science, EBSCO, and Google Scholar databases. No filters were applied for dates, language, or publication type.

Transport modes and road traffic mortality in the Americas: Deaths among pedestrian and motorcycle users through the lifespan.

In the Americas, almost half of road traffic deaths occur among motorcycle users and pedestrians (23% and 22%, respectively). Recent individual country trends show that nations are experiencing changes in deaths depending on the mode of transport used. While national trends are useful, analyses of disaggregated data by sex and age may provide more information about the impact of traffic crashes at different stages of the life course.

Epanorin, a lichen secondary metabolite, inhibits proliferation of MCF-7 breast cancer cells.

Background: Epanorin (EP) is a secondary metabolite of the Acarospora lichenic species. EP has been found in lichenic extracts with antimicrobial activity, and UV-absorption properties have been described for closely related molecules; however, its antiproliferative activity in cancer cells has not yet been explored. It has been hypothesized that EP inhibits cancer cell growth.

The effect of an autologous cellular gel-matrix integrated implant system on wound healing.

Background: This manuscript reports the production and preclinical studies to examine the tolerance and efficacy of an autologous cellular gel-matrix integrated implant system (IIS) aimed to treat full-thickness skin lesions.

Methods: The best concentration of fibrinogen and thrombin was experimentally determined by employing 28 formula ratios of thrombin and fibrinogen and checking clot formation and apparent stability. IIS was formed by integrating skin cells by means of the in situ gelification of fibrin into a porous crosslinked scaffold composed of chitosan, gelatin and hyaluronic acid.

[Screening of the delta-F508 mutation and analysis of two Single Nucleotide Polymorphism of the CFTR gene, in a sample of the general population of Valparaíso, Chile].

Background: The Cystic Fibrosis (CF) carrier rate in Chile was estimated to be 1/40. CF is caused by mutations in the Cystic Fibrosis Transmembrane Conductance Regulator (CFTR) gene. Delta F508 mutation is the most common in CF patients in Chile and worldwide.

Zolpidem and triazolam do not affect the nocturnal sleep-induced memory improvement.

Rationale: It is widely accepted that sleep facilitates memory consolidation. Hypnotics (e.g.

A comparison of self-reported energy intake with total energy expenditure estimated by accelerometer and basal metabolic rate in African-American women with type 2 diabetes.

Objective: This study assesses the validity of dietary data from African-American women with type 2 diabetes by comparing reported energy intake (EI) with total energy expenditure (TEE) estimated by an accelerometer and basal metabolic rate (BMR).

Research Design And Methods: EI of 200 African-American women was assessed by three telephone-administered 24-h diet recalls using a multiple-pass approach. Physical activity was measured over a 7-day period by accelerometer, which also provided an estimate of TEE.

Assessment of physical education time and after-school outdoor time in elementary and middle school students in south Mexico City: the dilemma between physical fitness and the adverse health effects of outdoor pollutant exposure.

Strategies to promote lifelong physical activity among children are needed to stem the adverse health consequences of inactivity. However, the health effects in growing children of long-term exposure to a polluted atmosphere are of deep concern. The atmosphere of south Mexico City (SMC) is characterized by a complex mixture of air pollutants, including ozone, particulate matter, and aldehydes.

A randomized trial of an intervention to improve self-care behaviors of African-American women with type 2 diabetes: impact on physical activity.

Objective: To determine whether a culturally appropriate clinic- and community-based intervention for African-American women with type 2 diabetes will increase moderate-intensity physical activity (PA).

Research Design And Methods: In this randomized controlled trial conducted at seven practices in central North Carolina, 200 African-American women, > or =40 years of age with type 2 diabetes, were randomized to one of three treatment conditions: clinic and community (group A), clinic only (group B), or minimal intervention (group C). The clinic-based intervention (groups A and B) consisted of four monthly visits with a nutritionist who provided counseling to enhance PA and dietary intake that was tailored to baseline practices and attitudes; the community-based intervention (group A) consisted of three group sessions and 12 monthly phone calls from a peer counselor and was designed to provide social support and reinforce behavior change goals; and the minimal intervention (group C) consisted of educational pamphlets mailed to participants.
