title: Ultrasonographic evaluation of cecal appendix diameter in pediatric population

description: ABSTRACT Objective To stratify ultrasound samples in a pediatric population undergoing evaluation for acute appendicitis to examine the variability in cecal appendix diameter, in different age groups, and to determine whether there is a prevalent value for each age group. Methods A retrospective cross-sectional study with 196 children aged 0 to 15 years. Data were extracted from reports of ultrasound examinations carried out between 2008 and 2015. Children with sonographic diagnosis of appendicitis or other signs of periappendiceal inflammation were excluded. Results The evaluation of the anteroposterior measurement of the cecal appendix revealed a mean diameter of 4.14mm (standard deviation: 0.93mm; 95%CI: 3.86-4.14). Cecal appendix diameter did not differ significant between age groups. Conclusion Evaluation of the anteroposterior diameter of the cecal appendix in centimeters in a sample of 196 children aged 0 to15 years revealed a mean diameter of 4.14mm (standard deviation, 0.93mm. There were no significant differences in cecal appendix diameter following stratification by age. Results indicate a single value can be adopted for mean cecal appendix diameter in pediatric populations.

title: COVID-19 in kidney transplant recipients: what have we learned one year later? A cohort study from a tertiary center

description: Abstract Introduction: Kidney transplant (KT) recipients have a high risk for adverse outcomes from infections, such as COVID-19. Methods: We have retrospectively reviewed all KT recipients with documented COVID-19 between March 1, 2020, and March 15, 2021, and analyzed patients’ characteristics, clinical course, treatment, and outcomes. Results: We identified 123 patients, 72% were male, with a mean age of 54.5±13.0 years. Twenty percent were asymptomatic, 7% had a nosocomial transmission, and 36% of the remainder required hospitalization. Almost all admitted patients received oxygen, 30% required invasive mechanical ventilation (IMV), more than a half had acute kidney injury, with 10% requiring dialysis, and 20% died. Incidence was comparable to that of the Portuguese population, but the mortality rate was almost four times higher (SMR of 3.768 (95% CI:1.723-7.154). Higher body mass index (OR 1.275, P=0.001), lower baseline graft function (OR 0.968, P=0.015), and nosocomial transmission (OR 13.836, P=0.019) were associated with oxygen demand, whereas female gender (OR 3.801, P=0.031) and lower baseline kidney graft function (OR 0.955, P=0.005), but not body mass index, were associated with IMV and/or death. Conclusion: Mortality rate in KT patients was higher than in the general population and lower baseline kidney function was the most consistent marker for adverse outcomes.

title: Experimental composite containing silicon dioxide-coated silver nanoparticles for orthodontic bonding: Antimicrobial activity and shear bond strength

description: ABSTRACT Objective: This study aimed to investigate the antimicrobial activity and shear bond strength (SBS) of orthodontic brackets to bovine enamel using experimental composites with different concentrations of silicon dioxide-coated silver nanoparticles (Ag@SiO2 NPs). Methods: Fifty bovine incisors were divided into five groups according to the composite (n = 10): G1 - Control Group (Transbond XT Resin), G2 - Experimental composite without Ag@SiO2 NPs; G3 - Experimental composite with 0.5% of Ag@SiO2 NPs; G4 - Experimental composite with 1% of Ag@SiO2 NPs; G5 - Experimental composite with 3% of Ag@SiO2 NPs. The SBS test was performed using a universal mechanical testing machine, and the adhesive remnant index (ARI) was analyzed by optical microscopy. For the antimicrobial activity evaluation, Streptococcus mutans (S. mutans) biofilm was formed for three days in hydroxyapatite discs. Posteriorly, S. mutans colony forming units (CFU) were evaluated. For SBS analysis, Analysis of Variance was used, followed by the Tukey test, at a 5% statistical significance level. The CFU data were analyzed by Kruskal-Wallis, followed by Dunn as a post-hoc test. The ARI results were analyzed descriptively. Results: There was no statistically significant difference in SBS values between the experimental and control groups (p&gt;0.05). A 3% incorporation of Ag@SiO2 NPs statistically reduced the SBS values (p&lt;0.05) compared to the 1% group. The addition of 3% of Ag@SiO2 NPs to the composites significantly reduced S. mutans biofilm formation, compared to group G2 (p&lt;0.05). Conclusion: Composites incorporating 3% of Ag@SiO2 NPs presented similar SBS values compared to the control group, and showed significant antimicrobial activity.

title: Health surveillance of populations exposed to pesticides: agroecology and social participation

description: ABSTRACT Health surveillance of populations exposed to pesticides foresee the development of actions in a continuous and systematic way, in an intersectoral and participatory perspective, to support health promotion, with food and nutritional security and sovereignty, thus establishing a direct link with agroecology. This article aimed to analyze the development of the proposal in Pernambuco, considering articulation with agroecology and social participation. Documents of the federal government and the State Health Department of Pernambuco available on websites were analysed, based on two main categories: agroecology and social participation. Among the main results, the following stand out: a) the development of health promotion actions articulated with social movements, in accordance with the National Plan for Agroecology and Organic Production; b) the design and monitoring of actions in an intersectoral group; c) training of health professionals and rural workers based on the principles of agroecology; d) the implementation of the pesticide applicator portfolio, as a strategy for popular health surveillance. The proposal incorporated principles of agroecology in intersectoral and health promotion actions, with important social participation. The adopted practices represent an important strategy to overcome the biomedical clinical model of health surveillance.

title: COMPARISON OF AFFECTIVE RESPONSES DURING SCHOOL PHYSICAL EDUCATION CLASSES WITH DIFFERENT RECOVERY TIMES

description: ABSTRACT This study aimed to verify the effect of exercise recovery time on the affective responses during a circuit training in physical education classes. Forty-six apparently healthy young adolescents (twenty-one girls) (12.85 ± 0.94 years; 49.7 ± 8.93 kg; 1.59 ± 0.08 cm; 19.51 ± 3.28 kg/m2) participated in this study. Were submitted participants for two physical education classes, based on circuited model of the same intensity, but with different recovery times (2 min and 1 min). The study was carried out in two phases: baseline and intervention. Affect, Arousal, and Ratings of Perceived Exertion data were analyzed using paired t-tests, considering a significance level of p &lt; 0.05. The class with longer rest time (2 min) provided greater affection (t(45) = 3.586; p &lt; 0,001) and less perceived effort (t(45) = 2.295; p = 0,026). The intensity manipulation strategy was effective in providing different affective responses, in which classes perceived as more intense, resulting in the decline of affect.

title: Environmental and Plant Variables Influence Dalbergia nigra (Fabaceae) Phenology - Implications for Seed Production

description: Abstract Studies of plant phenology in the Atlantic Forest can be enhanced by a greater understanding of the factors regulating vegetative and reproductive cycles. Dalbergia nigra (Vell.) Allemão ex Benth. is endemic and vulnerable in the Atlantic Forest. We analyzed abiotic aspects and plant traits that modulate the phenologies of D. nigra by monitoring 135 individuals in four subpopulations from different remnant forests for 24 months. The growth and shapes of the plants, as well as environmental variables, were determined. Circular analysis evidenced phenological variations among subpopulations and evaluation periods. Multiple factor analysis evidenced that phenological variations are mainly correlated with precipitation, temperature, and tree height. The combination of environmental conditions and plant characteristics affect synchronicity and phenological intensity. Low fruiting intensity (less than 50%) limits seed production and recruitment. We emphasize the importance of forest remnants and the need to increase D. nigra populations in future reforestation projects.

title: Spatial inequality in the purchase of food from family agriculture for school feeding in Brazil

description: ABSTRACT The study aims to analyze the fulfillment of the use of at least 30% of the National School Feeding Program (PNAE) resources for the acquisition of food from family agriculture in Brazil, from 2013 to 2016. This is a longitudinal ecological research. Data was collected through public data available at the National Education Development Fund (FNDE). Thematic and spatial correlation maps were constructed for analysis of the spatial distribution of the purchase and trend analysis. It was verified that the percentage of municipalities that comply with the legal purchase requirement increased from 34.3% in 2013 to 43.7% in 2016, with the largest number of municipalities in the Southern region of the country with 72.5%, while only 26.1% in the Midwest, 27.4% in the North and 31.6% in the Northeast. The South region stands out when compared to the North, Northeast and Midwest (p =&lt;0.001). The trend analysis of the union’s annual budget resources showed an average growth of 30.8% (CI = 13.2-51.1), but with a decline between 2015 and 2016. It is concluded that there has been a progressive increase in the direct purchase of food from family farms for school feeding in Brazil from 2013 to 2016, although in unequal manner in different regions of the country.

title: Purchase of food from family farming for school feeding: the situation in Rio Grande do Norte

description: ABSTRACT The objective was to characterize the scenario of acquisition of food from Family Farming (AF) for the National School Feeding Program (PNAE) in the municipalities of Rio Grande do Norte. An evaluative research with an ecological design, using data from the Collaborating Center for School Food and Nutrition of the Federal University of Rio Grande do Norte in 2017 and 2018. 31 municipalities were evaluated, analyzing the percentage of food purchases from AF for school meals, in addition to of the possible difficulties in this process, using variables related to governance and management, stability and availability of food. Of the evaluated municipalities, more than 50% purchased food from the AF in the previous year and confirmed the purchase in the current year. All reported using the centralized management model, 29% declared acquisition less than 30%, 9.7%, acquisition above 30%, and 61.3% were unable to inform. As for the main difficulties related to governance and management, intersectorial articulation and the public call notice were highlighted. Regarding food stability, the necessary hygienic-sanitary conditions were highlighted, and in relation to food availability, the purchase of organic food was shown to be a difficulty listed by 80.6% of the municipalities.
