Vaspin association with insulin resistance is related to physical activity and body fat in Brazilian adolescents: a cross-sectional study

Background: Vaspin is a newly-identified adipocytokine associated with insulin resistance (IR). Objective: The aim of this study was to investigate the correlation between plasma vaspin concentrations and IR and determine whether this association is affected by body composition, physical activity and pubertal stage in adolescents. Methods: Were studied 484 Brazilian adolescents aged 10-14 years whose anthropometric, clinical, biochemical, and lifestyle measurements were analized. We evaluated the correlation between vaspin and risk factors for IR in adolescents with normal and high body fat percentage (%BF) and did a logistic regression to calculate the odds ratio for IR according to vaspin quartiles sex specific for the sample. Results: Vaspin was positively correlated with IR in adolescents with high %BF (r = 0.23, p = 0.003). The logistic regression analysis adjusted for sex, age, BMI, and pubertal stage showed that adolescents in the 2nd (OR = 0.43, 95% CI = 0.23-0.80, p = 0.008) and 3rd (OR = 0.46, 95% CI = 0.25-0.85, p = 0.014) quartile of vaspin concentration had a lower risk for IR. When the model was adjusted for %BF and physical activity, the association remained statically significant only for adolescents in the 2nd quartile. Conclusion: Vaspin was correlated positively with risk factors associated with insulin metabolism in adolescents with high %BF. Vaspin was associated with a reduced risk of IR independently of BMI and pubertal stage and the association was influenced by body fat and physical activity in these adolescents.

Growth, lipogenesis and body composition of piracanjuba (Brycon orbignyanus) fingerlings fed different dietary protein and lipid concentrations

Piracanjuba (Brycon orbignyanus) is a Brazilian migratory fast-growing omnivore, very appreciated as a sport fish, which is threatened to extinction in Southern Brazil due to stock over exploitation and dam building. Therefore, efforts have been made to raise this fish in captivity for reintroduction and aquaculture purposes. In the present study, the effects of different dietary protein and lipid concentrations on piracanjuba fingerlings growth performance, feed utilization, body composition, hepatosomatic index (HSI) and activity of the lipogenic enzymes fatty acid synthetase (FAS), glucose-6-phosphate dehydrogenase (G6PD) and malic enzyme (ME) were investigated using a 2 x 3 factorial experiment. Six casein-gelatin based diets were prepared combining two protein (30% and 32%) and three lipid concentrations (5.5%, 8.8% and 12.1%). Eleven fish, average weight 11.30 +/- 0.1 g, were held in each of 18 100-1 aquaria, supplied with recirculating freshwater. Each diet was randomly assigned to triplicate groups of fish and fed to apparent satiation, twice a day for 100 d. Piracanjuba fingerlings' daily weight gain (0.36-0.40 g), specific growth rate (1.43-1.51%), feed utilization and HSI were not influenced by dietary protein or lipid concentration. However, body composition was directly affected by dietary treatment. An increase in body fat and dry matter was observed as dietary lipid increased, for both dietary protein concentrations tested. The activity of FAS was depressed by increasing dietary fat levels but the G6PD activity did not differ among dietary treatments, although ME activity showed some regulation by dietary protein. These results indicate that an increase from 5.5% to 12.1% in the dietary lipid, at a dietary protein concentration of 30% or 32%, promotes body fat accumulation in piracanjuba fingerlings with no improvement in growth, suggesting that the lipid requirement for this species should be 5% or less, when raised for commercial purposes. However, the additional energy reserve from body fat accumulation could be desirable for piracanjuba fingerlings produced for stock enhancement.

Growth and body nutrient deposition of two broiler commercial genetic lines

The objective of this work was to study growth and body nutrient deposition profiles of male and female Cobb and Ross broilers using Gompertz equations. A total number of 1,920 one- to 56-day-old broilers were used. A randomized experimental design in a factorial arrangement (2 strains x 2 sex), with 4 replicates of 120 birds each, was applied. Diets were formulated to supply the nutrient requirements recommended by the genetic companies. A sample of birds was weekly weighed and sacrificed after 24 hours fasting. Carcasses were de-feathered and weighed again. The parameters of the Gompertz equation for body weight and its components (water, ashes, protein, and fat) were estimated. An interaction (p<0.05) between sex and breed was observed for mature weight (Wm) (kg), growth rate (b) (daily) and time at maximum growth rate (t*) (day) of body weight, and body water and ash. Cobb was presented earlier growth and body protein and ash deposition. Ross strain was superior in body water deposition.

Trauma in critically ill children : transfusion and osmotherapy practices

Les accidents sont la cause la plus fréquente de décès chez l’enfant, la plupart du temps à cause d’un traumatisme cranio-cérébrale (TCC) sévère ou d’un choc hémorragique. Malgré cela, la prise en charge de ces patients est souvent basée sur la littérature adulte. Le mannitol et le salin hypertonique (3%) sont des traitements standards dans la gestion de l’hypertension intracrânienne, mais il existe très peu d’évidence sur leur utilité en pédiatrie. Nous avons entrepris une revue rétrospective des traumatismes crâniens sévères admis dans les sept dernières années, pour décrire l’utilisation de ces agents hyperosmolaires et leurs effets sur la pression intracrânienne. Nous avons établi que le salin hypertonique est plus fréquemment utilisé que le mannitol, qu’il ne semble pas y avoir de facteurs associés à l’utilisation de l’un ou l’autre, et que l’effet sur la pression intracrânienne est difficile à évaluer en raison de multiples co-interventions. Il faudra mettre en place un protocole de gestion du patient avec TCC sévère avant d’entreprendre des études prospectives. La transfusion sanguine est employée de façon courante dans la prise en charge du patient traumatisé. De nombreuses études soulignent les effets néfastes des transfusions sanguines suggérant des seuils transfusionnels plus restrictifs. Malgré cela, il n’y a pas de données sur les transfusions chez l’enfant atteint de traumatismes graves. Nous avons donc entrepris une analyse post-hoc d’une grosse étude prospective multicentrique sur les pratiques transfusionnelles des enfants traumatisés. Nous avons conclu que les enfants traumatisés sont transfusés de manière importante avant et après l’admission aux soins intensifs. Un jeune âge, un PELOD élevé et le recours à la ventilation mécanique sont des facteurs associés à recevoir une transfusion sanguine aux soins intensifs. Le facteur le plus prédicteur, demeure le fait de recevoir une transfusion avant l’admission aux soins, élément qui suggère probablement un saignement continu. Il demeure qu’une étude prospective spécifique des patients traumatisés doit être effectuée pour évaluer si une prise en charge basée sur un seuil transfusionnel restrictif serait sécuritaire dans cette population.

WOMEN, CYCLING, AND THE PUBLIC SPHERE: HOW DISCURSIVE AND COMMUNITY PRACTICES AFFECT ENGAGEMENT

This thesis considers the impact that discursive and community practices have on women’s access to the public sphere by examining female cyclists and a cycling community in Miami, Florida via interviews and observation. In the interviews, female cyclists frequently reported fears for their safety, including concern over harassment, when riding in public space. I interviewed participants of the cycling community and observed Emerge Miami’s meetings and events, where publicly organized cycling excursions were a major component. Using the theoretical and methodological lenses of Feminist Critical Discourse Analysis and Communities of Practice, I examined the interviews to understand how participants discursively framed and contextualized gender-based harassment. I found two meta-discourse frames in operation: a normative frame (that essentially accepted the status quo) and a feminist frame (that challenged the “naturalness” of women’s harassment as just what one had to live with). The feminist frame offered a pathway for women to exert control over their experiences and alter the cultural understanding of harassment’s meaning and effect. The local community practices of Emerge Miami also challenged the normative frames that often silence women, employing explicitly invitational practices, which demonstrates how local discursive and social activity can impact and increase women’s involvement by creating a more accessible space for women to engage with their local cycling community.

Comparison of body composition and body fat distribution of patients following a cardiac rehabilitation program and sedentary patients

O objectivo desta investigação foi analisar a composição corporal e a distribuição de gordura corporal de sujeitos com doença das artérias coronárias (DAC) envolvidos num programa estruturado de reabilitação cardíaca (PRC) e sujeitos com DAC que não participam em qualquer PRC. População e métodos: A amostra foi constituída por 62 sujeitos do sexo masculino, caucasianos, com DAC diagnosticada, oriundos de cada um de dois grupos estudados: grupo C/PRC (n=31) foi constituído por sujeitos que participavam na fase IV de um PRC há mais de um ano (idade: 58 + 10 anos); grupo S/PRC (n=31) foi constituído por sujeitos que não participavam em qualquer PRC (idade: 59 + 12 anos). Foi observada a composição corporal e distribuição de gordura corporal dos sujeitos da amostra, através da análise por Densitometria por Raio-X de Dupla Energia (DXA). Foram recolhidas medidas antropometricas. Resultados principais: sujeitos que não participaram em qualquer PRC apresentaram valores superiores, aos sujeitos do grupo C/PRC, nas variáveis massa corporal total (p<0,05), IMC (p<0,05), quantidade (kg) de massa gorda (MG) (p<0,05) e % MG (p<0,05). O grupo S/PRC tambem apresentou valores superiores de MG tronco (p<0,01), % MG tronco (p<0,01), MG abdominal total (p<0,01), % MG abdominal total (p<0,01), MG visceral (p<0,01), % MG visceral total (p<0,01), MG abdominal subcutânea (p=0,05) e na razao MG abdominal total/MG (p<0,05). Tambem foi possivel observar maior prevalencia de obesidade (IMC> 30 kg/m2) no grupo S/PRC (p<0,05), ou seja, neste grupo um em cada tres sujeitos era obeso, enquanto no grupo C/PRC apenas um em cada dez sujeitos foi assim classificado. Nao foram observadas diferencas significativas entre os grupos nas outras variaveis em estudo, incluindo a massa isenta de gordura total e regional. Conclusões: Os resultados encontrados permitem concluir que os sujeitos que não participaram em qualquer PRC apresentaram um perfil de composição corporal e de distribuicao de gordura corporal menos adequado a sua condicao clinica. A maior quantidade de gordura em depositos especificos, assim como os valores superiores encontrados na razao MG abdominal total/MG, confirmam que estes sujeitos apresentaram uma distribuicao de gordura mais adversa. Estes resultados vao ao encontro da tendencia observada em estudos de intervencao em sujeitos com DAC.

Determinants of environmental accounting and reporting practices in portuguese local entities

Purpose – The purpose of this paper is to develop environmental accounting and reporting practices (EARPs) by Portuguese local entities and their determining factors. Design/methodology/approach – Data were obtained through a postal survey. In order to measure the degree of development of environmental accounting and reporting practices index was developed, which reflects the extent to which a set of eight EARPs have been implemented by the 69 Portuguese local entities included in the sample. Three variables are considered in this study as possible factors that drive the development of environmental management practices (EMPs) by local entities, namely, size of entity, accounting framework, degree of development of EMPs. Findings – Results indicate the degree of development of EARPs in Portuguese local entities is low. Additionally, accounting regulation and the degree of development of EMPs are explaining factors of the degree of development of environmental accounting practices in Portuguese local entities. Originality/value – This study adds to the international research on environmental accounting in public sector by providing empirical data from a country, Portugal, where empirical evidence is still relatively limited.

By-catch and discarding practices in five Algarve (southern Portugal) metiers

The catches and discards of trawlers, seiners and trammel netters were studied in the Algarve (southern Portugal) using observers onboard commercial fishing vessels. Species diversity was high, with 236 species recorded as occasionally, frequently or regularly discarded. Mean discard rates per trip were 0.13, 0.20, 0.27, 0.62 and 0.70, respectively, for trammel nets, demersal purse seines, pelagic purse seines, fish trawls and crustacean trawls, with high variability in terms of discard volume and discard rate, This was especially so for se ncrs where from 0 to 100% of the total catch might be discarded. No significant relationships were found between discard quantity or discard rate and characteristics of the fishing vessels sampled within each metier (total length, TAB, hp, kW). Based on the above discard rates and the official landings, it was estimated that in 1996, Algarve trawlers discarded 9000-13000 tonnes (t) while seiners discarded 5500-8200 t. Discarding practices in these fisheries are reviewed and the reasons for discarding are presented by species and metier basis. The results support the need for more studies on the factors contributing to discarding, variability in discard quantities and rates, the fate of discards and their importance to the marine ecosystem, and on ways of reducing by-catch and discarding in these fisheries.
