Body mass to predict 4-6 rm of pectoral and leg muscles exercises in bodybuilders / Predicción de 4-6 rm de ejercicios de piernas y pectorales por masa corporal / Predição de 4-6 rm de exercicios de perna e peitoral pela massa corporal

ABSTRACT Introduction: Submaximal strength testing appears to be valid to prescribe the intensity for strength training protocols that reduce the risk of injuries and testing time. Objective: This study aimed to assess the predictive ability of body mass parameters to estimate 4-6 repetitions maximum (4-6 RM) of Leg press 45°, Chest press, and Pull-down exercises. Methods: Eleven male bodybuilders (age 38.27 ± 10.48 years) participated in this study. Participants completed an incremental external load up to find the load allowing them to perform 4 to 6 maximal repetitions for each exercise in random order. The starting load was 50% of body mass for chest press and pull-down exercises and 100% for leg press. The load increment after each set was 20 kg for lower limb exercises and 10 kg for upper body exercises. Results: Results revealed that body mass had good to optimal relationships with 4-6 RM for all three exercises. Results showed that body mass had a good prediction ability for all three criterion measures. Conclusion: The prediction equations suggested in this study may allow coaches to estimate the 4-6 RM of leg press 45°, chest press, and pull-down performances. Evidence Level IV; Case series.

Association between childhood anthropometric indicators and bone mineral density in adulthood / Associação entre indicadores antropométricos na infância e densidade mineral óssea na idade adulta

ABSTRACT Objective: This study aimed to verify the association between childhood anthropometric indicators and areal bone mineral density (aBMD) in adulthood. Methods: Repeated measures of 137 subjects (68 females) were obtained in childhood (9.2±1.5 years of age) and adulthood (22.3±1.7 years of age). aBMD (g/cm2) was assessed for whole body, lumbar spine, upper and lower limbs, and femoral neck in adulthood using dual-energy X-ray absorptiometry. Anthropometric measurements of body weight (BW), height, triceps and subscapular skinfolds were obtained in childhood. The anthropometric indicators used were BW, body mass index (BMI), and sum of skinfolds (ΣSF). Simple linear regression was used to assess the association between childhood anthropometric indicators and aBMD in adulthood, controlled by chronological age and stratified by sex, with 5% statistical significance. Results: In females, multiple associations were observed between anthropometric indicators and aBMD, with higher coefficients for BMI (β=0.020; R2=0.20; p<0.01 for right femoral neck to β=0.008; R2=0.16; p<0.01 for upper limbs), followed by BW (β=0.003; R2=0.21; p<0.01 for upper limbs to β=0.008; R2=0.20; p<0.01 for right femoral neck) and ΣSF (β=0.001; R2=0.06; p<0.01 for upper limbs to β=0.005; R2=0.12; p<0.01 for right femoral neck). In males, associations were observed only for the lumbar spine region (β=0.016; R2=0.09 for BMI to β=0.004; R2=0.06; p<0.01 for ΣSF). Conclusions: Anthropometric indicators of childhood proved to be sensitive predictors of aBMD in adulthood, especially in females. BMI indicated a greater association with aBMD in both sexes.

RESUMO Objetivo: O objetivo do estudo foi verificar a associação entre os indicadores antropométricos da infância com a área da densidade mineral óssea (aDMO) na idade adulta. Métodos: Medidas repetidas de 137 sujeitos (68 do sexo feminino) foram obtidos na infância (9,2±1,5 anos de idade) e idade adulta (22,3±1,7 anos de idade). A aDMO (g/cm2) foi avaliada para todo o corpo, coluna lombar, membros superiores e inferiores e colo do fêmur na idade adulta usando a absorciometria radiológica de dupla energia (DXA). Medidas antropométricas de peso corporal, estatura e dobras cutâneas das regiões tricipital e subescapular foram obtidas na infância. Os indicadores antropométricos utilizados para as análises foram o peso corporal (PC), o índice de massa corporal (IMC) e o somatório de dobras cutâneas (ΣDC). Regressão linear simples controlada pela idade e estratificada por sexo foi empregada para avaliar a associação entre os indicadores antropométricos do período da infância na aDMO na idade adulta, com significância estatística de 5%. Resultados: No sexo feminino, múltiplas associações foram observadas entre os indicadores antropométricos e a aDMO, com maiores coeficientes para IMC (β=0,020; R2=0,20; p<0.01 para colo do fêmur direito a β=0,008; R2=0,16; p<0,01 para membros superiores), seguido da PC (β=0,003; r2=0,21; p<0,01 para membros superiores a β=0,008; r2=0,20; p<0,01 para colo do fêmur direito) e ΣDC (β=0,001; R2=0,06; p<0,01 para membros superiores a β=0,005; R2=0,12; p<0,01 para colo do fêmur direito). No sexo masculino, associações ocorreram apenas na região da coluna (β=0,016; R2=0,09 para IMC a β=0,004; R2=0,06; p<0,01 para ΣDC). Conclusões: Indicadores antropométricos da infância mostraram ser sensíveis preditores da aDMO na idade adulta, especialmente no sexo feminino. O IMC indicou maior associação com a aDMO em ambos os sexos.

Excesso de peso pré-gestacional e ácidos graxos poli-insaturados no leite humano: modelo teórico de causalidade / Pre-gestational overweight and polyunsaturated fatty acids in human milk: theoretical causality model

Resumo Inúmeros estudos têm se detido na avaliação da associação entre o excesso de peso pré-gestacional e os ácidos graxos poli-insaturados no leite humano. Todavia, diante da complexidade de fatores de risco potencialmente confundidores, é recomendável a utilização de ferramentas gráficas para identificar possíveis vieses. O objetivo deste artigo é propor um modelo teórico de causalidade utilizando o gráfico acíclico direcionado entre o excesso de peso pré-gestacional e os ácidos graxos poli-insaturados no leite humano. Foi realizada ampla revisão da literatura para identificar as variáveis com relações causais com a exposição e/ou desfecho. A escolha das variáveis para ajuste seguiu o algoritmo gráfico que compreende seis critérios para a seleção de um conjunto mínimo de variáveis potencialmente confundidoras. Condições socioeconômicas, intervalo interpartal, idade materna e padrão de consumo alimentar foram as variáveis ajustadas a fim de se estimar o efeito total do excesso de peso pré-gestacional sobre o conteúdo dos ácidos graxos poli-insaturados no leite humano. O conjunto mínimo de variáveis encontrado pelo presente estudo pode ser utilizado na análise de outros estudos que avaliem essa associação.

Abstract A number of studies have focused on the evaluation of the relationship between pre-pregnancy overweight and polyunsaturated fatty acids content in human milk. However, given the complexity of potentially confounding risk factors, the use of graphical tools is recommended to identify possible biases. This article aims to propose a theoretical model of causality using the directed acyclic graph between pre-pregnancy overweight and polyunsaturated fatty acids content in human milk. Methods: An extensive literature review was performed to identify variables with causal relationships with exposure and/or outcome. The choice of variables for adjustment followed the graphic algorithm that comprises six criteria for selecting a minimum set of potentially confounding variables. Socioeconomic conditions, interpartum interval, maternal age and food consumption pattern were the variables that would have to be adjusted in order to estimate the total effect of pre-pregnancy overweight on polyunsaturated fatty acids content in human milk. The minimum set of variables found in the present study can be used in the analysis of other studies that evaluate this association.

Comparison of nutritional status and growth curves of children and adolescents in the city of Goiânia, Goiás: cross-sectional study

ABSTRACT BACKGROUND: Nutritional status and growth curves can affect cognitive development, increase the risk of infection, and contribute to the development of chronic diseases. Its etiology is related to food, socioeconomic, and maternal conditions. However, to date, no data on these parameters exist in the state of Goiás, Brazil. OBJECTIVE: To compare the nutritional status and growth curves of children and adolescents in the city of Goiânia, Goiás, Brazil. DESIGN AND SETTING: This was a cross-sectional study. A total of 529 individuals were recruited from a primary health center in the municipality. METHODS: To assess nutritional status, the sample was divided into three categories: 3-4, 5-10, and 11-19 years, with z-score classification considering body mass index for age. The classification of growth curves was performed considering the median height values for age, assuming two references: (a) young Brazilian population and (b) one recommended for international use. The independent sample T-test was used to compare anthropometric variables. RESULTS: The results showed that the classification of eutrophics represents a predominant percentage between both sexes (men: 03-04 = 55.4%; 05-10 = 57.6%; 11-19 = 53.5 % and women: 03-04 = 53.5%; 05-10 = 63.9%; 11-19 = 56.9%), and growth curves showed differences in specific periods in both sexes. CONCLUSIONS: It can be concluded that children and adolescents from the city of Goiânia present as predominance the eutrophic nutritional status, followed by the risk of overweight, underweight, obesity, and malnutrition of both sexes.

Association between the ratio of dietary vitamin A to body weight and hypertension in children / 中国学校卫生

Objective@#To explore the relationship between the ratio of dietary vitamin A (VitA) to body weight and hypertension among children, so as to provide a reference for blood pressure control through dietary nutritional interventions and childhood hypertension prevention.@*Methods@#Utilizing the baseline survey and followup sample data from the Healthy Children Cohort established in urban and rural areas of Chongqing from 2014 to 2019, structured quantitative dietary questionnaire and selfdesigned questionnaire were used to investigate the information of dietary intake and socioeconomic characteristics of 15 279 children, as well as blood pressure, height, weight measurement. The ratio of dietary VitA to body weight was divided into four groups based on quartiles [≤P25(Q1), >P25~P50(Q2), >P50~P75(Q3), >P75(Q4)]. Generalized linear regression models and Logistic regression models were used to analyze the correlation between ratio of dietary VitA to body weight with blood pressure levels and prevalence of hypertension.@*Results@#The results of the 2014 baseline survey indicated that, after adjusting for confounding factors such as demographic indicators and nutritional intake, significant differences were observed in systolic blood pressure (SBP), diastolic blood pressure (DBP), and mean arterial pressure (MAP) among different groups categorized by the ratio of dietary VitA to body weight (F=157.57, 44.71, 95.92, P<0.01). The baseline ratio of dietary VitA to body weight in children exhibited a negative correlation with DBP, SBP and MAP at baseline and in 2019[baseline: β(95%CI)=-0.65(-0.89--0.42), -0.22(-0.42--0.01), -0.36(-0.56--0.16); 2019: β(95%CI)=-0.77(-1.34--0.19), -0.62(-1.21--0.02), -0.77(-1.34--0.19), P＜0.05]. Compared to Q1 group, the risk of hypertension decreased among children in Q4 at baseline and followup in 2019 [OR(95%CI)=0.63(0.49-0.81), 0.18(0.08-0.42), P<0.01].@*Conclusions@#The ratio of dietary VitA to body weight is significantly negatively correlated with blood pressure levels among children, and dietary VitA deficiency is an independent risk factor for hypertension among children. Measures should be taken to actively adjust childrens dietary nutrition and reduce the risk of childhood hypertension.

Effect of Moringa olifera leaves on growth and gut microbiota of Nile tilapia (Oreochromis niloticus)

Abstract The study was conducted to evaluate the effect of Moringa olifera on the growth and gut health of Tilapia (Oreochromis niloticus). The feed having 30% crude protein was prepared as an experimental diet with 4%, 8% and 10% M. olifera leaf supplementation, respectively. The control diet was devoid of M. olifera leaves. The 10 weeks feeding trial was carried out on 60 fish in aquaria. Fish was fed @ 3% of body weight twice a day. Diet with the high level of inclusion of M. olifera leaves significantly increased the growth rate, Survival Rate (SR), Specific Growth Rate (SGR) and Feed Conversion Efficiency (FCE) in all treatment groups compared to the control group. Similarly, Feed Conversion Ratio (FCR) gradually decreased and found highly-significant. To check the gut health of the Tilapia, random samples were selected and dissected. Nutrient agar was used as culture media to check the growth of bacteria. Pour Plate Method was used for viable colonies count by colony counter. Through staining method, the different bacteria such as Escherichia coli, Salmonella, Shigella and Pseudomonas aeruginosa were identify abundantly in the intestine of control diet fish but less number present in treatment diets groups. These results showed that M. olifera leaves up to 10% of dietary protein can be used for Nile tilapia for significant growth and healthy gut microbiota of fish.

Resumo O estudo foi conduzido para avaliar o efeito da Moringa olifera no crescimento e saúde intestinal da tilápia (Oreochromis niloticus). A ração com 30% de proteína bruta foi preparada como dieta experimental com 4%, 8% e 10% de suplementação de folhas de M. olifera, respectivamente. A dieta controle foi desprovida de folhas de M. olifera. O ensaio de alimentação de 10 semanas foi realizado em 60 peixes em aquários. O peixe pesava 3% do peso corporal duas vezes ao dia. A dieta com alto nível de inclusão de folhas de M. olifera aumentou significativamente a taxa de crescimento, taxa de sobrevivência (SR), taxa de crescimento de sobrevivência (SGR) e eficiência de conversão alimentar (FCE) em todos os grupos de tratamento em comparação com o grupo de controle. Da mesma forma, a taxa de conversão de alimentação (FCR) diminuiu gradualmente e foi considerada altamente significativa. Para verificar a saúde intestinal da tilápia, amostras aleatórias foram selecionadas e dissecadas. O ágar nutriente foi usado como meio de cultura para verificar o crescimento das bactérias. O método da placa de Verter foi usado para a contagem de colônias viáveis por contador de colônias. Através do método de coloração, diferentes como Escherichia coli, Salmonella, Shigella e Pseudomonas aeruginosa foram identificados abundantemente no intestino de peixes da dieta controle, mas em menor número nos grupos de dieta de tratamento. Esses resultados mostraram que M. olifera deixa até 10% da proteína dietética e pode ser usado para tilápia do Nilo para um crescimento significativo e microbiota intestinal saudável de peixes.

Actividad física durante el embarazo y su relación con la ganancia de peso gestacional / Physical activity during pregnancy and its relationship with gestational weight gain / Atividade física durante a gestação e sua relação com o ganho de peso gestacional

Objetivo: describir los patrones de actividad física de una cohorte de gestantes de nuestro medio y explorar su asociación con la ganancia de peso en cada uno de los trimestres del embarazo. Método: estudio descriptivo longitudinal sobre una muestra de 151 mujeres. Se utilizó el Cuestionario Internacional de Actividad Física para evaluar la actividad física durante el embarazo en función del volumen, intensidad y ámbito de realización. Se llevaron a cabo diferentes modelos de regresión lineal múltiple para analizar la asociación entre actividad física y ganancia de peso gestacional. Resultados: la actividad física disminuyó durante el embarazo, tanto en tiempo como en intensidad. El índice de masa corporal pre-gestacional fue el principal factor asociado con una menor ganancia de peso a lo largo de todo el embarazo. La influencia de la actividad física sobre la ganancia de peso gestacional se limitó al tercer trimestre del embarazo en el que se observó una asociación inversa entre ambas variables. Conclusión: los resultados de este estudio muestran un importante descenso de la actividad física en la época del embarazo y sugieren una influencia limitada de ésta sobre la ganancia de peso gestacional.

Association Between Hormone Therapy and Weight Gain in the Menopause Transition and After Menopause: A Systematic Review and Meta-Analysis

Objectives: to conduct a systematic review and meta-analysis in order to assess whether hormone therapy (HT) increases weight in women in the menopausal transition and after menopause. Method: this article proposes an update to the systematic review published in 2005 by the Cochrane Library (Kongnyuy EJ et al 2005) with reference to studies assessing weight changes in women receiving HT from 1986 to 2005. Following PRISMA recommendations, we included randomized controlled trials (RCTs) ) from May 2005 onwards from Medline, Embase, and the Cochrane CENTRAL databases. Standardized mean differences (SMD) and 95% confidence intervals (CI) were calculated. Two authors independently assessed the risk of biases in the selected studies. Results: ten RCTs were included, totaling 2,588 HT users and 764 non-users. Different regimens, dosages, and routes of administration in HT users were analyzed and compared to non-users. The results did not show statistically significant differences for most of the HT regimens evaluated. There was significant weight gain only in patients using EEC alone at dosages of 0.45 mg/day and 0.3 mg/day when compared to placebo (p 0.01); as well as in patients receiving esto-progestative combinations of 0.5 mg/day 17-beta-estradiol (E2) + 100 mg/day progesterone, with a 0.7 kg weight increase (p 0.032). On the other hand, the combinations of 1 mg/day estradiol valerate + 3 mg/day drospirenone showed a -1.0 kg reduction (p = 0.04), whereas a -0.2 kg reduction (p = 0.001) was identified in patients using 1 mg /day estradiol (E) + 0.5 mg norethisterone acetate (NETA). Tibolone therapy showed no statistically significant changes in weight. After performing a meta-analysis, the comparative results between users and non-users showed that there was a slight weight increase (+0.279 kg ; CI -1.71 to 2.27) in patients using 0.625 mg/day conjugated equine estrogen (CEE) + 2.5 mg/day medroxyprogesterone acetate (MPA). As for the patients receiving 2.5 mg/day Tibolone, weight gain (+0.670 kg; CI from -1.14 to 2.48) was also observed in them. However, these increases were not significant when compared to non-HT users. Conclusions: most regimens studied showed that patients using HT in the menopausal transition and after menopause did not show significant weight gain. The only combination that showed weight gain was 0.5 mg/day 17-beta-estradiol (E2) + 100 mg/day progesterone observed, while there was weight reduction in patients using 1 mg/day estradiol valerate + 3 mg/day drospirenone and 1 mg/day estradiol (E) + norethisterone acetate.

Objetivo: realizar uma revisão sistemática e meta-análise para avaliar se a terapia hormonal (TH) aumenta o peso em mulheres na transição menopausal e após a menopausa. Métodos: este artigo propõe uma atualização da revisão sistemática publicada em 2005 pela Cochrane Library (Kongnyuy EJ et al., 2005) com referência a estudos avaliando mudanças de peso em mulheres recebendo TH de 1986 a 2005. Seguindo as recomendações do PRISMA, incluímos ensaios clínicos randomizados (RCTs) de maio de 2005 em diante do Medline, Embase e dos bancos de dados Cochrane CENTRAL. Diferenças médias padronizadas (SMD) e intervalos de confiança de 95% (IC) foram calculados. Dois autores avaliaram independentemente o risco de vieses nos estudos selecionados. Resultados: foram incluídos dez ECRs, totalizando 2.588 usuários de HT e 764 não usuários. Diferentes esquemas, dosagens e vias de administração em usuários de HT foram analisados e comparados a não usuários. Os resultados não mostraram diferenças estatisticamente significativas para a maioria dos esquemas de TH avaliados. Houve ganho de peso significativo apenas nos pacientes que usaram apenas EEC nas doses de 0,45 mg/dia e 0,3 mg/dia quando comparados ao placebo (p 0,01); assim como em pacientes recebendo combinações estoprogestativas de 0,5 mg/dia de 17-beta-estradiol (E2) + 100 mg/dia de progesterona, com aumento de peso de 0,7 kg (p 0,032). Por outro lado, as combinações de 1 mg/dia de valerato de estradiol + 3 mg/dia de drospirenona apresentaram redução de -1,0 kg (p = 0,04), enquanto foi identificada redução de -0,2 kg (p = 0,001) nas pacientes que usaram 1 mg /dia estradiol (E) + 0,5 mg de acetato de noretisterona (NETA). A terapia com tibolona não mostrou alterações estatisticamente significativas no peso. Após realizar uma meta-análise, os resultados comparativos entre usuárias e não usuárias mostraram que houve um leve aumento de peso (+0,279 kg ; IC -1,71 a 2,27) em pacientes em uso de 0,625 mg/dia de estrogênio equino conjugado (CEE) + 2,5 mg/dia de acetato de medroxiprogesterona (MPA). Quanto aos pacientes que receberam Tibolona 2,5 mg/dia, também foi observado ganho de peso (+0,670 kg; IC de -1,14 a 2,48). No entanto, esses aumentos não foram significativos quando comparados aos não usuários de HT. Conclusões: a maioria dos esquemas estudados mostrou que as pacientes em uso de TH na transição menopausal e após a menopausa não apresentaram ganho de peso significativo. A única combinação que apresentou ganho de peso foi 0,5 mg/dia de 17-beta-estradiol (E2) + 100 mg/dia de progesterona, enquanto houve redução de peso nas pacientes que usaram 1 mg/dia de valerato de estradiol + 3 mg/dia de drospirenona e 1 mg/dia estradiol (E) + acetato de noretisterona.

Impacto da pandemia de Covid-19 no consumo alimentare treinamento de praticantes de musculação / Impact of the Covid-19 pandemic on food consumptionand training of bodybuilders

A pandemia de Covid-19 impactou a vida de milhares de pessoas no mundo, e mesmo com a vacinação o número de infectados foi elevado. Esta pesquisa teve como objetivo verificar o impacto da pandemia de Covid-19 no consumo alimentar e no treinamento de praticantes de musculação. Foi realizada uma pesquisa transversal, com 134 praticantes de musculação, de ambos os sexos, do Sudoeste do Paraná, Brasil, com idade entre 18 e 50 anos, em setembro de 2021. A pesquisa foi realizada através do siteGoogle Forms®, enviada aos voluntários através de mensagens diretas e mídias sociais. Os dados foram tabulados e analisados no software PSPP. A maioria dos pesquisados relatou percepção de aumento no apetite (50%) e de aumento da quantidade de alimentos ingeridos durante o dia (47%) e do peso corporal (41,8%), sendo que a maioria acreditava que o ganho de peso foi de gordura corporal. Ainda, 40,3% dos pesquisados referiram que a frequência de prática de musculação diminuiu durante a pandemia. Apesar disso, observou-se que os indivíduos relataram consumir mais frutas (50,7%), verduras (49,3%) e legumes (45,5%), e menos açúcar ou adoçantes (34,3%), bebidas açucaradas (31,3%) e lanches tipo fast food (29,9%). Foi possível concluir que apesar do impacto da pandemia na prática de musculação, percepção de aumento de apetite, peso e ingestão alimentar, notou-se melhora da qualidade do consumo alimentar dessa população.

The Covid-19 pandemic has impacted the lives of thousands of people around the world and even with vaccination, the number of infected was high. This research aimed to verify the impact of the Covid-19 pandemic on food consumption and training of bodybuilders. A cross-sectional survey was carried out with 134 bodybuilders, of both sexes, from the Southwest of Paraná, Brazil, aged between 18 and 50 years, in September 2021. The survey was carried out through the Google Forms® website, sent to volunteers through direct messages and social media. Data were tabulated and analyzed using the GNU PSPP 1.4.1-g79ad47 software. Most respondents reported an increase in appetite (50%), the amount of food eaten during the day (47%) and body weight (41.8%), with the majority believing that the weight gain was due to fat body. Also, 40.3% of respondents reported that the frequency of bodybuilding practice decreased during the pandemic. Despite this, it was observed that individuals reported consuming more fruits (50.7%), green (49.3%), vegetables (45.5%) and less sugar or sweeteners (34.3%), sugary drinks (31.3%) and fast food snacks (29.9%). It was possible to conclude that despite the impact of the pandemic on bodybuilding practice, perception of increased appetite, weight and food intake, there was an improvement in the quality of food consumption in this population.

Carbohydrate counting as a strategy to optimize glycemic control in type 1 diabetes mellitus

ABSTRACT Objective: The objective of this study was to verify the impact of carbohydrate counting (CC) on glycemic control and body weight variation (primary and secondary outcomes, respectively) between consultations in patients with diabetes mellitus (T1D) followed at a tertiary hospital in southern Brazil in a public health system environment. We also sought to investigate CC adherence. Materials and methods: This retrospective cohort study included 232 patients with T1D who underwent nutritional monitoring at a referral hospital for diabetes care between 2014 and 2018. To assess primary and secondary outcomes, data from 229 patients, 49 of whom underwent CC during this period and 180 individuals who used fixed doses of insulin, were analyzed. The impact of CC on glycemic control was assessed with the mean glycated hemoglobin (HbA1c) level at all consultations during the follow-up period. Results: In the model adjusted for the most confounders (except pregnancy), the mean HbA1c was better in the CC group (8.66 ± 0.4% vs. 9.36 ± 0.39%; p = 0.016), and body weight variation was lower (0.13 ± 0.28 kg vs. 0.53 ± 0.24 kg; p = 0.024). Adherence to CC was reported in 69.2% of consultations. Conclusion: CC optimized the glycemic control of individuals with T1D, resulting in less weight variation than in the fixed insulin dose group, which indicates that CC is an important care strategy for these patients.

Effect of mobile phone radiofrequency electromagnetic radiations on oxidative stress and feeding behaviour in Sprague Dawley (SD) rats

Objectives: Radiofrequency electromagnetic radiation (RF-EMR) from mobile phones is known to produce a stress response because of its effect on hypothalamus. Mobile phones have become an integral part of our lives with increasing usage not only in terms of number of users but also increase in talk time. The present study aimed to study the effect of mobile phone radiofrequency electromagnetic radiations on oxidative stress and feeding behaviour assessment in Sprague Dawley (SD) rats. Materials and Methods: Twelve male SD rats of 10–12 weeks old, weighing 180–220 g, were housed and allowed to acclimatise in a room with 12:12 h light-dark cycle with ad libitum amount of food and reverse osmosis (RO) water before the start of the study. Then, rats were divided into control and RF-EMR exposed groups, and everyday feed intake and body weight were measured. At the end of the study period, blood sample was collected through retro orbital puncture for biochemical investigations. Results: The present study showed significant increase in malondialdehyde and serum corticosterone levels and decrease feeding behaviour in rats exposed to RF-EMR in rats exposed to RF-EMR. Conclusion: This study proves that mobile RF-EMR causes oxidative stress and oxidative damage leading to decreased feeding behaviour in SD rats.

Molecular aspects of COVID-19 and its relationship with obesity and physical activity: a narrative review

Abstract BACKGROUND: Severe acute respiratory syndrome coronavirus 2 has several mechanisms of action related to inflammatory responses, especially in individuals diagnosed with obesity. This hyperinflammatory clinical profile resulting from the association between obesity and coronavirus disease 2019 (COVID-19) may be attenuated by regular physical activity. OBJECTIVE: The aim of this study was to review the evidence on the consequences of physical inactivity and physical activity on COVID-19 in patients with obesity. DESIGN AND SETTING: Narrative review at the Bahiana School of Medicine and Public Health in Salvador, Brazil. METHODS: We searched evidence on the association of COVID-19 with physical activity and obesity using the following keywords: "covid-19," "physical activity," and "obesity". The databases used were MEDLINE (PubMed), ScienceDirect, and Virtual Health Library. Studies published from 2019 to 2021 and available in Portuguese, English, and Spanish were included. The final search was conducted on September 26, 2021. RESULTS: We identified 661 studies in the database, among which 71 were considered for inclusion in the narrative review of the molecular aspects of COVID-19 and its relationship with physical activity and obesity. CONCLUSION: This literature review enabled the perception of the relationship between the molecular mechanisms of COVID-19 and obesity. Regular physical activity had various benefits for the inflammatory condition of the studied population, highlighting moderate-intensity.

Determinants of poor sleep quality in adults during the coronavirus disease pandemic: COVID-Inconfidentes, a population-based study

ABSTRACT BACKGROUND: The coronavirus disease (COVID-19) pandemic has adversely affected the health of the global population, with sleep quality being one of the affected parameters. OBJECTIVES: To evaluate sleep quality and its associated factors in adults during the COVID-19 pandemic in Brazil. DESIGN AND SETTING: A population-based cross-sectional serological survey of 1,762 adults in the Iron Quadrangle region of Brazil. METHODS: The Pittsburgh Sleep Quality Index was used to assess sleep quality. Sociodemographic variables, health conditions, health-related behaviors, anxiety, vitamin D levels, weight gain/loss, and pandemic characteristics were assessed using a structured questionnaire. Univariate and multivariate analyses using Poisson regression with robust variance were performed to identify factors associated with sleep quality. RESULTS: More than half of the participants reported poor sleep quality (52.5%). Multivariate analysis revealed that the factors associated with poor sleep quality included living alone (prevalence ratio [PR] = 1.34; 95% confidence interval [CI]: 1.04-1.73), anxiety disorder (PR = 1.32; 95% CI: 1.08-1.62), 5.0% weight loss (PR = 1.21; 95% CI: 1.02-1.44), 5.0% weight gain (PR = 1.27; 95% CI: 1.03-1.55), vitamin D deficiency (PR = 1.16; 95% CI: 1.01-1.35), and COVID-19 symptoms (PR = 1.29; 95% CI: 1.10-1.52). CONCLUSIONS: Our study revealed that more than half of the participants experienced poor sleep quality during the COVID-19 pandemic. Factors associated with poor sleep quality included vitamin D deficiency and weight changes related to the pandemic.

Effectiveness and safety of secukinumab in ankylosing spondylitis and psoriatic arthritis: a 52-week real-life study in an Italian cohort

Abstract Background Secukinumab has shown high efficacy in randomized controlled trials in both ankylosing spondylitis (AS) and psoriatic arthritis (PsA). Here, we investigated its real-life effectiveness and tolerability in a cohort of AS and PsA patients. Methods We retrospectively analyzed medical records of outpatients with AS or PsA treated with secukinumab between December 2017 and December 2019. ASDAS-CRP and DAS28-CRP scores were used to measure axial and peripheral disease activity in AS and PsA, respectively. Data were collected at baseline and after 8, 24, and 52 weeks of treatment. Results Eighty-five adult patients with active disease (29 with AS and 56 with PsA; 23 males and 62 females) were treated. Overall, mean disease duration was 6.7 years and biologic-naïve patients were 85%. Significant reductions in ASDAS-CRP and DAS28-CRP were observed at all time-points. Body weight (in AS) and disease activity status at baseline (particularly in PsA) significantly affected disease activity changes. ASDAS-defined inactive disease and DAS28-defined remission were achieved in comparable proportions between AS and PsA patients, at both 24 weeks (45% and 46%) and 52 weeks (65.5% and 68%, respectively); male sex was found an independent predictor of positive response (OR 5.16, P = 0.027). After 52 weeks, achievement of at least low disease activity and drug retention were observed in 75% of patients. Secukinumab was well-tolerated and only mild injection-site reactions were recorded in 4 patients. Conclusion In a real-world setting, secukinumab confirmed great effectiveness and safety in both AS and PsA patients. The influence of gender on treatment response deserves further attention.

Impact of different sports on body mass of female university students / Impacto de distintos esportes sobre as massas corporais de universitárias / Impacto de diferentes deportes en la masa corporal de estudiantes universitarias

ABSTRACT Introduction A healthy body depends on several factors, and physical exercise is one of the main factors. Research results on the physical health of female university students show that although the general health status of Chinese female students is good, the quality of physical performance at university continues to show a slow downward trend. Objective To explore the effects of different exercises on the fat mass and lean weight indices of female university students. Methods 60 female students who participated in aerobics and ball games training in the Physical Education Department of a university were randomly divided into a control group and a training group, with 30 volunteers in each group. The experimental group performed intensive aerobics training and ball training. In contrast, no intervention was performed in the control group, and indicators were collected and analyzed according to current literature. Results After eight weeks of the intervention protocol, the body weight, body fat weight, lean weight, body surface area, and body fat ratio of the control group had no significant changes from the period before the experiment (P > 0.05). In the training group, fat weight decreased significantly (p<0.01), lean mass weight increased significantly (p<0.01), body fat ratio decreased (p<0.01), and body weight and body surface area had no significant changes (p>0.05). PTH and FSH in the training group were significantly higher than in the control group (P < 0.05). As the aerobic exercise level improved in the experimental group, the weight and abdominal skinfold thickness in the exercise group showed a downward trend. Conclusion There is a general correlation between BMI and body fat content and its body distribution in college women. Compared to men, BMI is better suited to describe the fat metabolism of college women. Level of evidence II; Therapeutic studies - investigation of treatment outcomes.

The efficacy of liraglutide combined with intragastric balloon on weight loss

SUMMARY OBJECTIVE: Intragastric balloon placement is an effective method for weight reduction. The aim of this study was to evaluate the efficacy of combining liraglutide with intragastric balloon. METHODS: Initially, demographic data of patients such as age, gender, comorbid diseases, adverse events, initial weight, height, body mass index, percent body fat, and waist-hip ratio were collected. Weight, body mass index, percent body fat, and waist-hip ratio were measured in the second, third, fourth, fifth, and sixth months. Then, intragastric balloon was removed and liraglutide was stopped. RESULTS: A total of 50 patients were included in the study, of whom 28 (56%) were in Group A (intragastric balloon) and 22 (44%) were in Group B (plus liraglutide). Weight change at the time of balloon removal was higher in Group B [median weight change 13.8 (7.8 min to 16.8 max) versus 7.9 (4.8 min to 11.8 max); p<0.01]. When the weight, percent body fat, body mass index, and waist-hip ratio changes were compared according to gender, no significant difference was observed in the groups. Comorbid diseases were hypertension in 7 patients (4 in Group A and 3 in Group B) and diabetes in 9 patients (5 in Group A and 4 in Group B). No statistical significance was found. CONCLUSION: Liraglutide has benefits in terms of weight, percent body fat, and body mass index reduction when administered with intragastric balloon.

ABSTRACT BACKGROUND: Obesity is associated with different medical conditions, such as cardiologic, respiratory, gastrointestinal, and genitourinary, and constitutes a severe health problem. AIMS: This study aimed to evaluate the use of intragastric fluid-filled balloon in the reduction of weight and other measurements related to body composition. METHODS: This is a retrospective, monocentric study involving all patients who opted for the intragastric balloon Spatz® placement from January 2018 to July 2019, with fulfillment of inclusion and exclusion criteria. The patients were analyzed after 6 and 12 months after the intragastric fluid-filled balloon placed. RESULTS: A total of 121 subjects were included in this study, with 83 (68.6%) females and 38 (31.4%) males. The mean age was 36 years and height was 1.64±0.09. Weight mean and standard deviation was 89.85±14.65 kg, and body mass index was 33.05±4.03; body mass index decreased to 29.4 kg/m2 with a mean weight of 79.83 kg, after 12 months of follow-up. There were statistical differences between body mass index and the 12 months in fat percentage, fat-free mass (kg), visceral fat area, and basal metabolic rate. There was a significant variation according to gender, with males having highest reduction. The percentage of excess weight loss was 46.19, and the total weight loss was 9.24 at the end of the study. CONCLUSIONS: The study demonstrated a benefit of intragastric fluid-filled balloon on weight loss after 12 months. At the end of treatment, body mass index and the measurements of body composition were significantly lower. Men benefited more than women from the treatment.
