Evaluation on body weight and its relation with abdominal circumference in the diagnosis of obesity in school students in Cacoal municipality, RO, Brazil

Obesity in school-aged children has reached epidemic levels, which is considered a chronic disease. Researchers have been on alert, given the rising prevalence of obesity in the last few decades. The objective of this study is to evaluate the relation between body weight and abdominal circumference as a predictor for nutritional status in school students from 7 to 12 years of age in the municipality of Cacoal, RO, Brazil. The current study is of a descriptive nature, with cross-sectional and quantitative analysis. The study sample had 482 school students, of both genders, 230 male ones and 252 female ones, divided into school students from the urban and teaching rural teaching areas. Body Mass Index (BMI), abdominal circumference, and body weight were the variants analyzed. Reading with general comprehension strategies. It was possible to notice that 13% of the school students from the rural area were obese. On the other hand, 25% of the school students from the urban area, including both genders, were obese. There was a significant relation in body weight variant versus abdominal circumference in both genders, in the two areas studied. The body weight variant showed a significant relation with abdominal circumference and with body weight index in both genders

The use of BMI and Abdominal Circumference in the Diagnosis of Obesity in Schools: a Systematic Review

To verify body composition or body weight distribution in a more traditional way, isolated body weight or height adjusted weight has been used. In the last 5 years, evaluations have been used to verify the distribution of this fat, where these measures are more preventive to health.The objective of the study was to analyze the studies that indicate the use of BMI and waist circumference as a tool to diagnose obesity. The current study is a systematic review, where it followed the criteria of a systematized review and meta-analysis proposed by the PRISMA protocol. The criteria adopted for the selection of articles were the use of the following variables for obesity: BMI, Circumference of abdomen, relation of C.A with stature and C.A and body weight. After consulting the databases selected to search for articles, 1,846 articles were identified on the topic of interest with the descriptors (obesity in schoolchildren). 410 articles were found on the Scielo platform, 150 articles were found on the Bireme platform. In the Pubmed platform 1,236 articles and finally in the Scopus platform a total of 50 articles. After the exclusion, 16 articles were used for the analysis. The majority of the studies in the area of collective health are concluded, but only the BMI isolated for the diagnosis are indicated as evaluation measures. More recent studies indicate an evolution in the way of evaluating. As can be seen in the sixteen articles analyzed

Analysis of histological frequency and pediatric cancer in Rondônia, Western Amazonia (Brazil)

Objective:Describe the histological and cancer frequency in children and adolescents attended at the Hospital de Base Dr. Ary Pinheiro and the Hospital de Barretos / Rondônia, Western Amazonia, in the years 2014 and 2015. Method: This is a descriptive, quantitative and transverse study. We used a structured instrument containing a series of variables, such as gender, age, histological types, more frequent neoplasms, lymphomas, leukemias, among others. We asked The Comitê de Ética em Pesquisa em Seres Humanos (Research Ethics Committee) to dispense the Informed Consent Form because the study did not require intervention on the patient or collection of biological material, and no possibility of constraints on patients and their relatives. Results: From 75 cases, 32 (42.7%) were female and 43 (57.3%) were male. Regarding the distribution of patients according to the age group, 21 (28.0%) were younger than 4 years, 12 (16.0%), 5 to 9 years, 17 (22.6%) from 10 to 14 and 25 (33.4%) from 15 to 19. The most frequent histological types by gender were leukemias of myeloproliferative diseases and myelodysplastic diseases with 30% and 50% new cases in the period, followed by lymphomas and reticuloendothelial neoplasms with 16.65% and 20, 0% of the histological types in the period. Leukemia in the hematopoietic and reticuloendothelial system (C42) is the most frequent cancer in both, female and male gender, with 47.5% of cancers in the biennium. The second group of cancers in children from 0 to 19 years old and location of the primary tumor is the encephalon carcinoma (C71), with 11.25% of the new cases. Conclusions: The results presented with their proper nuances are in agreement with the data of studies carried out in Brazil and in other countries

Distance Functions and Normalization Under Stream Scenarios

Data normalization is an essential task when modeling a classification system. When dealing with data streams, data normalization becomes especially challenging since we may not know in advance the properties of the features, such as their minimum/maximum values, and these properties may change over time. We compare the accuracies generated by eight well-known distance functions in data streams without normalization, normalized considering the statistics of the first batch of data received, and considering the previous batch received. We argue that experimental protocols for streams that consider the full stream as normalized are unrealistic and can lead to biased and poor results. Our results indicate that using the original data stream without applying normalization, and the Canberra distance, can be a good combination when no information about the data stream is known beforehand.Comment: Paper accepted to the 2023 International Joint Conference on Neural Network

Ansiedad competitiva y clima motivacional en jóvenes futbolistas de competición, en relación con las habilidades y el rendimiento percibido por sus entrenadores

En este estudio se analizan las relaciones existentes entre la ansiedad competitiva (en sus facetas cognitiva y somática) y el clima motivacional percibido (de ego y de maestría) en una población de 54 jóvenes futbolistas decompetición de edad media de 9,45 años, respecto de la percepción de sus habilidades y rendimiento deportivos por parte de sus 4 entrenadores, que también participaron en el estudio. Para ello se les administró las versiones españolas del SAS-2 (Sport Anxiety Scale-2, Smith, Smoll, Cumming y Grossbard, 2006) y el MCSYS (Motivational Climate Scale for Youth Sports,Smith, Cumming y Smoll, 2008), así como dos escalas ad hoc para evaluar la percepción de su habilidad y rendimiento. Los resultados muestran, por una parte, que los jóvenes futbolistas perciben y discriminan claramente los climas motivacionales, que se distribuyen casi al 50% entre ego y maestría; por otra, que aparece ansiedad competitiva, aunque más cognitiva que somática, y que no existe relación significativa con las percepciones de habilidad y rendimiento por parte de los entrenadores. Finalmente, estos resultados se discuten y se comparan con otros similares en poblaciones preadolescentesThis study analysed the relationships between competitive anxiety (both cognitive and somatic) and perceived motivational climate (ego and mastery) in 54 young competitive soccer players (mean age: 9.45 years), related to their four coaches' perceptions of the soccer players' skills and performance. We administered the Spanish versions of the SAS-2 (Sport Anxiety Scale-2, Smith, Smoll, Cumming and Grossbard, 2006) and the MCSYS (Motivational Climate Scale for Youth Sports, Smith, Cumming and Smoll, 2008), along with two ad hoc scales to evaluate perceived skills and performance.The results show that 1) young players perceived and discriminated clearly between motivational climates (which were more or less equally distributed between ego and mastery orientations), 2) some performance-related anxiety (mostly cognitive rather than somatic) appeared and 3) no significant relationships were found between their coaches' perceptions of their skills and their performance. Lastly, the results are discussed and compared with similar results from preadolescent player

A comunidade de insetos endófagos de Asteraceae em Cerrados de São Paulo

A survey of the endophagous insects fauna associated to Asteraceae capitula was carried out from 2000 to 2002 in eight cerrado sensu stricto sites located in the Brazilian state of São Paulo. Sixty-four endophagous species of Diptera and Lepidoptera were recorded from 49 asteracean host plants. Approximately half of the species were obtained from a single locality, with a large proportion emerging from a single sample (unicates). Thirty percent of the species were singletons (i.e. only one individual was recorded). The large proportion of rare species suggests a high species turnover among localities. Lepidopteran species were recorded on more host species than dipterans, confirming their more polyphagous food habit, also observed in other Brazilian biomes and in Europe. We conclude that the studied cerrado localities, all within São Paulo State, are isolated with its invertebrate fauna composed of many rare and exclusive species. We suggest that the maintenance of Asteraceae biodiversity and their endophagous insects depend on the conservation of all cerrado remnants in the state.No presente estudo foi realizado um levantamento da fauna de insetos endófagos de capítulos de Asteraceae (Compostas), de 2000 a 2002, em oito localidades de cerrados sensu stricto no estado de São Paulo. Foram obtidas 64 espécies de endófagos (dípteros e lepidópteros) de 49 espécies de hospedeiras. Aproximadamente metade das espécies foi obtida de apenas uma área, e destas uma grande proporção ocorreu em apenas uma amostra (unicatas). Trinta por cento das espécies foram consideradas singletons (apenas um indivíduo foi obtido). A grande quantidade de espécies raras sugere uma forte troca de espécies entre diferentes áreas. Lepidópteros foram registrados em mais espécies hospedeiras que dípteros, confirmando o já observado para o mesmo sistema de insetos e plantas em outros ambientes no Brasil e Europa. As áreas de cerrado sensu stricto estudadas no estado de São Paulo encontram-se isoladas, com uma grande parte da fauna de invertebrados composta por muitas espécies raras e exclusivas. Diante deste quadro, sugere-se que a manutenção da biodiversidade de Asteraceae e seus endófagos em seus níveis atuais depende da conservação de todo o conjunto de remanescentes de cerrado do estado.458468Fundação de Amparo à Pesquisa do Estado de São Paulo (FAPESP

Evidence for lack of direct causality between pain and affective disturbances in a rat peripheral neuropathy model

[Epub ahead of print]Chronic pain is frequently accompanied by the manifestation of emotional disturbances and cognitive deficits. While a causality relation between pain and emotional/cognitive disturbances is generally assumed, several observations suggest a temporal dissociation and independent mechanisms. We therefore studied Sprague-Dawley rats that presented a natural resistance to pain manifestation in a neuropathy model (spared nerve injury [SNI]) and compared their performance in a battery of behavioral paradigms-anxiety, depression and fear memory-with animals that presented a pain phenotype. Afterward, we performed an extensive volumetric analysis across prefrontal, orbitofrontal and insular cortical areas. The majority of SNI animals manifested mechanical allodynia (low threshold [LT]), but 13% were similar to Sham controls (high threshold [HT]). Readouts of spontaneous hypersensivity (paw flinches) were also significantly reduced in HT and correlated with allodynia. To increase the specificity of our findings, we segregated the SNI animals in those with left (SNI-L) and right (SNI-R) lesions and the lack of association between pain and behavior still remains. Left-lesioned animals, independent of the LT or HT phenotype, presented increased anxiety-like behaviors and decreased well-being. In contrast, we found that the insular cortex (agranular division) was significantly smaller in HT than in LT. To conclude, pain and emotional disturbances observed following nerve injury are to some extent segregated phenomena. Also, HT and LT SNI presented differences in insular volumes, an area vastly implicated in pain perception, suggesting a supraspinal involvement in the manifestation of these phenotypes.This work has been funded by the European Regional Development Fund (FEDER), through the Competitiveness Factors Operational Programme (COMPETE) and the Northern Portugal Regional Operational Programme (NORTE 2020) under the Portugal 2020 Partnership Agreement (project NORTE-01-0145-FEDER-000023).
