To evaluate the usual consumption of ultra-processed foods (UPF) and its association with body mass index (BMI), physical activity (PA), age, and sex in adults living in Brasília City, Brazil.

A total of 506 individuals aged ≥ 20 years old were interviewed. Dietary intake was assessed with two non-consecutive 24-h food recalls. The distributions of usual intakes of energy and the amount of UPF were estimated using the Iowa State University method. The association of age, BMI, PA, and sex with the proportions of UPF consumption (%Kcal and %grams) was investigated with linear regression models.

UPF represented 9.2% of the total dietary consumption (grams/day) and 25% of total energy intake. Compared to eutrophic, subjects with obesity consumed a higher percentage of UPF in grams, whereas subjects with overweight had a higher percentage of UPF in kilocalories. The share of UPF in energy intake was lower in male than female individuals, and PA and age were inversely associated with UPF consumption.

Careful monitoring of intake of UPF is recommended. Its consumption should be reduced among people with overweight/obesity and sedentary individuals. Appropriate choices for methods to evaluate the usual distribution of intake will strengthen future analysis of UPF assessment.

To evaluate the association between dental visits and variation in the glycated hemoglobin index (A1C) of patients with type 2 diabetes (T2DM) with well or not well glycemic control over time.

Patients with T2DM, A1C ≥ 7% (not well-controlled) and < 7% (well-controlled), who attended a primary care service and were followed up from January 2010 to May 2018. The outcome was the variation of A1C obtained from reference laboratories. At the beginning of the study, a questionnaire with behavioral, clinical, and socioeconomic information was carried out. Multiple linear regression analyses tested interaction terms of all variables with the initial glycemic level (not well-controlled or well-controlled).

The sample consisted of 507 people, 65% women, and 66% individuals 55 to 74 years old, followed on average for 5.4 years. There was an interaction (p = 0.01) between dental visits and initial A1C. Patients not well-controlled with at least one dental visit had an average reduction in A1C of -0.56 percentage point (95%CI -1.06 - -0.56), whereas the well-controlled group who also had at least one dental visit had an increase of 0.34 percentage point (95%CI -0.18 - 0.87).

Dental visits were associated with an improvement in A1C of approximately a half-percentage point in patients who had the initial A1C considered as not well-controlled.

Given the collapse of hospital care in Manaus in January 2021 and the results of three recent preprints, each that reports increased transmissibility of the P.1 variant, we propose some urgent measures. Genomic surveillance based on multi-step diagnostics, starting with RT-PCR type tests and up to sequencing, should be established. Efforts to identify reinfections associated with this variant and the update of its definition in protocols should be prioritized, and studies on the efficacy of currently available vaccines in Brazil concerning the new variant should be conducted. We also propose improving the Brazilian health surveillance system such that genomic surveillance is coordinated and thereby better able to respond to future emergencies in a more timely fashion. We call on the public agents involved in health surveillance to share data and information regarding the epidemic in a clear, fast and transparent way. MEK activity Finally, we propose a greater engagement in inter-institutional cooperation of all those involved in the response and production of knowledge about the pandemic in our country.
To analyze changes in the lifestyles of Brazilian adolescents during the COVID-19 pandemic.

Cross-sectional study carried out with adolescents who participated in the survey "ConVid Adolescentes - Pesquisa de Comportamentos". The indicators related to lifestyles before and during the COVID-19 pandemic were evaluated consumption of healthy and unhealthy foods, physical activity and sedentary behavior, smoking and consumption of alcohol. Prevalence and 95% confidence intervals were calculated for the total population and according to sex and age group.

A total of 9,470 adolescents participated in the study. During the period of social distancing, there was an increase in the prevalence of vegetables consumption (from 27.34 to 30.5%), frozen foods (from 13.26 to 17.3%), chocolates and sweets (from 48.58 to 52.51%), and time in front of screens (from 44.57 to 70.15%). On the other hand, there was a decrease in the practice of physical activity (from 28.70 to 15.74%) and in the consumption of alcohol (from 17.72 to 12.77%). Differences were observed according to sex and age group.

The results show changes in the lifestyle of adolescents and an increase in health risk behaviors.

However, these hydrogels are mechanically brittle and prone to damage, prohibiting their use in emerging applications involving dynamic movement and large mechanical deformation. Here, we demonstrate that applying the concept of architecture to conducting polymer hydrogels can circumvent these impediments. A stereolithography 3D printing method is developed to successfully fabricate such hydrogels in complex lattice structures. The resulting hydrogels exhibit elastic compressibility, high fracture strain, enhanced cycling stability, and damage-tolerant properties despite their chemical composition being identical to their brittle, solid counterparts. Furthermore, concentrating the deformation to the 3D geometry, rather than polymer microstructure, effectively decouples the mechanical and electrical properties of the hydrogel lattices from their intrinsic properties associated with their chemical composition.
