title: Characterization of health and sanitation in a quilombola community in the surroundings of the capital of Brazil: a scoping review

description: ABSTRACT The Mesquita quilombola community has an identity closely related to land, however, nowadays, the relationship between health and sanitation is precarious due to the expansion of agribusiness and the real estate market. The aim of this study was to identify the health and sanitation aspects of the quilombo community of Mesquita of Cidade Ocidental, in the state of Goiás, Brazil. This review was structured using a scoping review method designed to synthesize evidence to help guide public policies and make practical decisions for the territory. The main results found in health aspects were the importance of the Basic Health Unit, of agroecology, and of alternative therapies. As for sanitation, they were water supply and treatment/disposal of solid waste. It is said that the strengthening and interdependence of human and environmental health, of the culture and ancestry of African history and recognition of territorial rights will enhance collective care with the support of different social actors. It is clear that the fight against slavery in Brazil still exists in the Mesquita quilombo, due to the invisibility and lack of assistance currently reflected by governmental actions.

title: THE INFLUENCE OF PHYSICAL ACTIVITY ON THE PREVALENCE OF LOW BACK PAIN AMONG THE PORTUGUESE POPULATION

description: ABSTRACT Objective: I) To investigate the influence of physical activity (PA) on levels of low back pain, and II) To classify the respondents regarding low back pain. Methods: Collection of responses, through an online questionnaire, from 199 adults aged between 18 and 65 years (36.05 ± 11.90 years). The following inclusion criteria were applied: I) Suffering or have suffered pain in the spine at some point in life; and as an exclusion criterion: I) Being outside the required age range. Results: Investigating the level of pain and the risk of low back pain, there was a significant association (r = 0.481; p≤0.01) between these two factors, indicating that the higher the levels of pain, the higher the risk of low back pain. Those who presented higher levels of chronic pain either did not practice any physical activity (58.8%), or practiced formal PA (42.9%) or practiced informal PA (30.7%). Those who had practiced physical exercise for three months or more mostly did not have chronic pain (70.1%). Conclusions: There was a decrease in chronic low back pain which was associated with increased time and frequency of PA, as well as the practice of postural physical exercises. Level of Evidence I; Prognostic Studies— Investigating the Effect of a Patient Characteristic on the Outcome of Disease.

title: Effect of 8% arginine toothpaste on Streptococcus mutans in patients undergoing fixed orthodontic treatment: randomized controlled trial

description: ABSTRACT Objective: To assess the effect of toothpaste containing 8% arginine on Streptococcus mutans (S. mutans) in dental plaque around orthodontic brackets, and to draw a comparison with a regular fluoride toothpaste. Trial design: A single-center, parallel-arm, triple-blind, randomized controlled trial was conducted. Methods: The clinical trial was conducted at the Orthodontic Clinic, School of Dentistry, Shiraz University of Medical Sciences, Shiraz, Iran. Seventy-two patients (age range: 15-30 years) who required fixed orthodontic treatment were recruited and randomly assigned to arginine and fluoride groups. Randomization was performed using RANDOM.ORG online software, and the participants were divided into two parallel groups, with a 1:1 allocation ratio. Patients were requested to brush their teeth twice daily for 30 days with an experimental toothpaste. Plaque sampling was performed at two intervals, namely at the beginning of the study (T0) and 30 days later (T1). Real-time PCR was used to assess plaque samples in terms of the number of S. mutans surrounding stainless steel brackets in orthodontic patients. A triple-blind design was employed. Results: The baseline characteristics (age, sex, and the relative number of S. mutans) between the groups were similar (p&gt;0.05). Only the arginine group showed a significant decrease in the relative number of bacteria between T0 and T1 (p=0.02). Conclusion: Arginine is an important prebiotic agent in maintaining healthy oral biofilms, and prevent dental caries during fixed orthodontic treatments. Trial registration: The trial was registered at the Iranian Registry of Clinical Trials (IRCT20181121041713N2), https://en.irct.ir/user/trial/42409/view.

title: EFFECT OF AN INTERVENTION WITH DIGITAL GAMES AND WEBGAMES ON INTRINSIC MOTIVATION IN SCHOOLS

description: ABSTRACT The objective of this study was to analyze the effect of an intervention with digital games associated with webgames on the intrinsic motivation of children from a public school in Florianópolis, Santa Catarina (Brazil). 50 students (52% girls) participated in this design study of non-randomized pedagogical intervention study, with a mean age of 6.7 (± 0.54) years. Two classroom groups were transformed into two research groups: 1) intervention group (preview experience of digital games on the computer and webgames during physical education classes); and 2) control group (only experience of webgame). The Intrinsic Motivation Inventory was the instrument used, and for intra and intergroup comparison, the Generalized Estimation Equations method was used, adopting a significance level of 5%. No isolated effect of the group or interaction between group vs moment was identified, which indicates that the group submitted to the intervention did not differ from the control group over time in terms of motivation. It is concluded that the type of pedagogical intervention performed was not able to increase the intrinsic motivation OF GROUP I, suggesting the need for adaptations in the structure and strategies of the intervention for future research.

title: EFFECT OF VARIED PLYOMETRIC TRAINING IN LAND AND AQUATIC MEDIUM ON ANAEROBIC POWER OF ATHLETES

description: ABSTRACT The aim of the present study was to find out the effect of varied plyometric training (land plyometric training, aqua plyometric training and weighted vest aqua-plyometric training) on anaerobic power of school athletes. A total of forty eight (n= 48) district level school athletes were randomly selected. All the subjects were divided into four equal groups: i) land plyometric training group (n=12), ii) aqua plyometric training group (n=12), iii) aqua-plyometric training with weighted vest group (n=12) and iv) control group (n=12). The varied plyometric training was intervened for fourteen weeks in the respective training groups. In the present study, anaerobic power was considered as the dependent variable, and it was measured by Margaria-Kalamen power test. To draw statistical inferences on anaerobic power among the groups in pre and post intervention conditions, ANCOVA was used, followed by Tukey’s LSD post-hoc test. The significance of the means was tested at the 0.05 level. Different plyometric training groups improved significantly with respect to the control group in anaerobic power. Therefore, various plyometric training was found as an effective means for developing anaerobic power. A significant difference was also observed between the aqua-plyometric training with weighted vest group and land plyometric training group in anaerobic power. However, rest of the experimental groups didn’t differ significantly. Aqua-plyometric training with weighted vest is a more effective training method than land plyometric training for improving the anaerobic power of the school athletes.

title: Genetic diversity in creole genotypes of Amazon chicory

description: ABSTRACT Amazon chicory is still a little-known vegetable despite its great agronomic potential. The characterization of chicory genotypes concerning genetic divergence is a key step for breeding programs, as it allows the selection of superior individuals and to explore the variability and complementarity of characteristics via interbreeding between newly generated genotypes. In this context, this study aimed to evaluate the genetic divergence among Amazon chicory creole genotypes from the northern Brazilian states of Pará and Rondônia based on morpho-agronomic traits. We conducted an experiment in a randomized block design with eight chicory genotypes (treatments) and four replications. Both quantitative and qualitative characteristics were evaluated. Genetic divergence was estimated via squared generalized Mahalanobis distance (D2), considering only quantitative characters, and the genotypes were subsequently clustered via the UPGMA method. Analysis of variance showed significant differences among genotypes for all studied characteristics, except shoot fresh weight. The UPGMA grouped the genotypes into three clusters, which demonstrated that the genotypes from Colares and Santarém Novo (Pará) (Chic-02 and Chic-04) were the most divergent as compared to the genotypes from Castanhal and Santa Isabel do Pará (Pará). Qualitative characteristics showed a monomorphic behavior and, therefore, were not used to assess genetic divergences. To obtain segregating populations with complementary characteristics, crossbreeding between the two most divergent clusters is recommended.

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: ASSOCIATION BETWEEN FREQUENCY OF PHYSICAL EDUCATION CLASSES AND HEART RATE VARIABILITY IN ADOLESCENTS BOYS: A CROSS-SECTIONAL STUDY

description: ABSTRACT Physical inactivity is associated with low heart rate variability (HRV) in adolescents. However, whether the number of physical education (PE) classes impact HRV remains unclear. This cross-sectional study verified the association between the frequency of PE classes and HRV parameters in male adolescents. This study included 1152 boys (16.6 ± 1.2 years). The quantity of PE classes was assessed though questionnaire and the adolescents were stratified accordingly (no PE class; one PE class/wk; ≥2 PE classes/wk). Time- (SDNN, RMSSD, PNN50) and frequency-domains (LF, HF, sympathovagal balance) of HRV were obtained. Generalized Linear Models were used for comparing the HRV parameters according to the quantity of PE classes, adjusting for confounders. There was no difference in HRV measures of time: (SDNN, p = 0.77; RMSSD, p=0.72; PNN50, p=0.83) and frequency (LF, p=0.61; HF, p=0.61; sympathovagal balance, p=0.60) between the different frequencies of PE classes. The frequency of PE classes in not associated with HRV parameters of male adolescents.
