Objectives: to describe and compare the mean values of the body composition and the peak expiratory flow (PEF) in primigravidae and multigravidae and, to determine its correlation with obstetric, anthropometric and body composition variables. Method: it was performed a cross-sectional study of 120 healthy pregnant women at low risk, including 77 primigravidae and 43 multigravidae. The PEF was measured by spirometry and the body composition by multisegmental electrical impedance. The unpaired t test was used to compare the groups and the Pearson correlation test was used to determine the association between PEF and independent variables. A multiple linear regression was used to estimate the relationship between the dependent variable, the PEF and the independent variables. Results: the body composition variables in multigravidae women showed higher values compared to the primigravidae, being statistically significant, except for fat mass. In primigravidae, the PEF was correlated significantly with maternal age and height. In multigravidae, the PEF was correlated with maternal age, height, pre-pregnancy and current weight, total body water, extracellular water, fat mass, lean mass and fat-free mass. A Multiple linear regression analysis showed that, in primigravidae, height and maternal age were associated with PEF, being responsible for explaining 14.5% of its variability. The current weight and the maternal age explained 42.3% of peak flow variability in multigravidae. Conclusion: The PEF seemed to be influenced by the number of pregnancies. Changes were observed in relation to the body composition, as it was evidenced in correlation with the PEF in multigravidae women. Keywords: Pregnancy. Spirometry. Weight gain.

Flat jockeys in Great Britain (GB) are classified as apprentices if they are aged less than 26 years and/or have ridden less than 95 winners. To gain experience, apprentices are allocated a weight allowance of up to 7 lb (3.2 kg). Given that there is no off-season in GB flat horseracing, jockeys are required to maintain their racing weight all year round. In light of recent work determining that current apprentices are considerably heavier than previous generations and that smaller increases have been made in the minimum weight, the aim of this study was to assess if the minimum weight in GB was achievable. To make the minimum weight (50.8 kg) with the maximal weight allowance requires a body mass of ∼46.6 kg while maintaining a fat mass >2.5 kg (the lowest fat mass previously reported in weight-restricted males). Thirty-two male apprentice jockeys were assessed for body composition using dual-energy X-ray absorptiometry. The mean (SD) total mass and fat mass were 56 (2.9) kg and 7.2 (1.8) kg, respectively. Given that the lowest theoretical body mass for this group was 51.2 (2.3) kg, only one of 32 jockeys was deemed feasible to achieve the minimum weight with their current weight allowance and maintaining fat mass >2.5 kg. Furthermore, urine osmolality of 780 (260) mOsmol/L was seen, with 22 (out of 32) jockeys classed as dehydrated (>700 mOsmols/L), indicating that body mass would be higher when euhydrated. Additionally, we observed that within new apprentice jockeys licensed during this study (N = 41), only one jockey was able to achieve the minimum weight. To facilitate the goal of achieving race weight with minimal disruptions to well-being, the authors’ data suggest that the minimum weight for GB apprentices should be raised.

Smoking leads to disease and disability as well as harm nearly every organ of the body. Furthermore, smoking of tobacco is known to cause pulmonary dysfunction and lead to complications, pain, or even death. This study aims to measure the risk factors for the respiration of carbon monoxide among smokers. A cross-sectional design was implemented by involving 156 smokers in Karyajaya Subdistrict, Palembang City. The dependent variable was carbon monoxide levels (ppm), while the independent variables were smoking frequency, duration, and the last period of smoking. The carbon monoxide levels (ppm) measured with a PiCO + Smokerlyzer® device from Bedfont Scientific Limited were the research tool and the independent variables of the questionnaire. The pearson Correlation and multiple linear regression were used for the analysis. The results of the multiple linear regression analysis revealed that smoking duration assessment is related to carbon monoxide respiration after controlling smoking frequency, the last period of smoking, and the distance of residence to sources of exposure. The smoker's respiration of carbon monoxide level was 72.5% influenced by the duration, frequency, last period of smoking, and distance of residence to sources of exposure. Reducing the frequency of smoking and stopping may prevent and control carbon monoxide respiration.

Abstract The aim of this study was to analyze the association between body composition and performance in the karate specific aerobic test (KSAT). This is a study carried out with thirteen athletes (6 females) with a mean age of 20.7 ± 4.2 years, affiliated to the Pernambuco Federation of Karate Associations, were developing this training routine during the 2018 season. Body mass and height were measured. To measure body composition, the body densitometry method was used by the x-ray double-ray absorptiometry (DEXA) technique. Karate Specific Aerobic Test was used to verify aerobic performance. Association analyzes were performed between body composition variables and KSAT performance using Pearson's correlation test and linear regression. All analyzes adopted a significance of p <0.05. KSAT performance was negatively correlated with total fat mass (r = -0.797; p = 0.001) and fat percentage (r = -0.757; p = 0.003). The linear regression model with the highest explanatory power included total fat and KSAT (adjusted R² = 0.732; p <0.001) exhibited a negative association with total fat (? = -0.21; p <0.001), and the model that included % body fat and KSAT (adjusted R² = 0.708; p = 0.003) were negatively associated with% body fat (? = -22.937; p = 0.001), both adjusted for gender and age. There is a negative association between total fat mass, body fat percentage and karate specific aerobic test performance.

Gestational weight gain (GWG), which is more or less of the recommended guidelines, has serious short- and long-term negative consequences for the health of the mother and children. Determining the dynamics of body composition during pregnancy is important for full antenatal care in order to prevent pathological weight gain and prevention of gestational complications.Objective: Our goal was to determine the proportion of fat component in the structure of GWG in women with normal body weight before pregnancy. Design: 153 pregnant women aged 18-43 years with normal pre-pregnancy body mass index (pBMI) were examined. BMI was calculated by using the standard formula of person’s weight in kilograms divided by the square of his height in meters (kg/m2). Total weight gain was calculated by subtracting the pre-pregnancy weight from the last measured weight before delivery. The body composition (fat mass (FM), fat-free mass (FFM), and the percentage of fat mass (%FM)) was calculated on the basis of bioelectrical impedance analysis (BIA) using the ‘DIAMANT-AIST’ analyzer (St. Petersburg). Statistical analyses were carried out using Statistical program "Statistica 5.5".Results: It has been established that in women of normal weight before pregnancy, GWG was directly proportional to an increase in the fraction of FM (r=0.87; p<0.001). In pregnant with the recommended GWG, FM increased monotonous in the first and second trimesters and subsequently stabilized. In patients with insufficient GWG, fat component increased similarly (p>0.05), however, it was accompanied by low growth of the FFM, especially in the third trimester (p<0.05). Pregnant women with excessive GWG were more likely to gain weight in the first trimester mainly due to the accumulation of FM (p<0.05), and this tendency remained until delivery r=0.99 (p<0.01).Conclusion: In women with normal GWG there is a monotonous increase in fat component in the first and second trimesters, and subsequently stabilized, which promotes adequate weight reduction after childbirth. In patients with high GWG, the excessive increase in the proportion of FM and, consequently, a rapid increase in weight in the first trimester of pregnancy, initiates further accumulation of adipose tissue and slows down its reduction in the postpartum period. In pregnant women with low weight gain there is adequate increase of FM but an insufficient increase of FFM, especially in the third trimester, which leads to the development of placental hypoplasia and small-for-gestational age.

The purpose of this study was to assess the body composition of male and female basketball athletes (n = 323) across season, year, and sport-position using air displacement plethysmography. An independent sample t-test assessed sport-position differences. An analysis of variance was used to assess within-subjects across season (pre-season, in-season, and off-season), and academic year (freshman, sophomore, and junior). For both men and women basketball (MBB, WBB) athletes, guards had the lowest body fat, fat mass, fat free mass, and body mass. No seasonal differences were observed in MBB, but following in-season play for WBB, a reduction of (p = 0.03) in fat free mass (FFM) was observed. Across years, MBB showed an increase in FFM from freshman to sophomore year, yet remained unchanged through junior year. For WBB across years, no differences occurred for body mass (BM), body fat (BF%), and fat mass (FM), yet FFM increased from sophomore to junior year (p = 0.009). Sport-position differences exist in MBB and WBB: Guards were found to be smaller and leaner than forwards. Due to the importance of body composition (BC) on athletic performance, along with seasonal and longitudinal shifts in BC, strength and conditioning practitioners should periodically assess athletes BC to ensure preservation of FFM. Training and nutrition programming can then be adjusted in response to changes in BC.

Long noncoding RNAs (lncRNAs) have an important role in various life processes of the body, especially cancer. The analysis of disease prognosis is ignored in current prediction on lncRNA–disease associations. In this study, a multiple linear regression model was constructed for lncRNA–disease association prediction based on clinical prognosis data (MlrLDAcp), which integrated the cancer data of clinical prognosis and the expression quantity of lncRNA transcript. MlrLDAcp could realize not only cancer survival prediction but also lncRNA–disease association prediction. Ultimately, 60 lncRNAs most closely related to prostate cancer survival were selected from 481 alternative lncRNAs. Then, the multiple linear regression relationship between the prognosis survival of 176 patients with prostate cancer and 60 lncRNAs was also given. Compared with previous studies, MlrLDAcp had a predominant survival predictive ability and could effectively predict lncRNA–disease associations. MlrLDAcp had an area under the curve (AUC) value of 0.875 for survival prediction and an AUC value of 0.872 for lncRNA–disease association prediction. It could be an effective biological method for biomedical research.
