Metabolic syndrome is a long-term complication of systemic chemotherapy for testicular germ cell tumor(TGCT).It is believed to be caused by secondary hypogonadism or toxic medicines because of orchidectomy followed by systemic chemotherapy.In this study,changes in the body composition of patients over time were quantitatively analyzed up to 24 months after chemotherapy.This study retrospectively analyzed 44 patients with TGCT who underwent chemotherapy at our institution from January 2008 to December 2016.Subcutaneous and visceral fat areas and psoas and skeletal muscle areas were measured by computed tomography before and immediately after chemotherapy as well as 3 months,6 months,12 months,and 24 months after chemotherapy.The subcutaneous and visceral fat indices and psoas and skeletal muscle indices were calculated as each area divided by body height squared.The total fat area had already significantly increased 3 months after the initiation of chemotherapy(P=0.004).However,it did not return to prechemotherapeutic levels even at 24 months after chemotherapy.The skeletal muscle area was significantly decreased at the end of chemotherapy(P<0.001);however,the value returned to baseline within 12 months.In multivariable analysis,the prechemotherapeutic skeletal muscle index and number of chemotherapy cycles were independently associated with the reduction of skeletal muscle at the end of chemotherapy(P=0.001 and P=0.027,respectively).In patients with TGCT,skeletal muscle mass decreased during chemotherapy and recovered within 12 months,whereas fat mass progressively increased from the initiation of chemotherapy until 24 months after chemotherapy.

Background The age of onset of hypertension(HTN)is decreasing,and obesity is a significant risk factor.The prevalence and racial disparities in pediatric HTN and the association between body composition and blood pressure are insufficiently studied.This study aimed to evaluate the prevalence of HTN in Chinese and American children and adolescents and to assess the relationship between various body composition indices and HTN.Methods Seven thousand,five hundred and seventy-three Chinese and 6239 American children and adolescents aged 8–18 years from the 2013–2015 China Child and Adolescent Cardiovascular Health study and the 2011–2018 National Health and Nutrition Examination Surveys were analyzed.Blood pressure and body composition(fat and muscle)were measured by trained staff.The crude prevalence and age-standardized prevalence rate(ASPR)of primary HTN and its subtypes[isolated systolic hypertension(ISH)and isolated diastolic hypertension(IDH)]were calculated based on 2017 American Academy of Pediatrics guidelines.Multivariable-adjusted linear regression coefficients and odds ratios(ORs)were calculated to assess the associations of body composition indicators with HTN,ISH and IDH.Results The ASPR of HTN was 18.5%in China(CN)and 4.6%in the United States(US),whereas the obesity prevalence was 7.4%and 18.6%,and the population attributable risk of HTN caused by overweight and obesity was higher in the US than in CN.Increased fat mass,muscle mass and body fat percentage mass were associated with a higher risk of HTN in both countries.The percent of muscle body mass had a protective effect on HTN and ISH in both countries[HTN(CN:OR=0.83,95%CI=0.78–0.88;US:OR=0.72,95%CI=0.64–0.81);ISH(CN:OR=0.87,95%CI=0.80–0.94;US:OR=0.71,95%CI=0.62–0.81)],and the protective effect was more common among children and adolescents with high levels of physical activity.Conclusions The burden of HTN in Chinese children and adolescents was substantial and much greater than that in the US,and the contribution of obesity to HTN was higher in t

Background:We compared body mass index(BMI),body fat,and skeletal muscle mass between(1) a mixed-sex nonathletic cohort of people with patellofemoral pain(PFP) and pain-free people,and(2) a nonathletic cohort of people with PFP and pain-free people subgrouped by sex(i.e.,men and women with PFP vs.pain-free men and women).Methods:This cross-sectional study included 114 people with PFP(71 women,43 men) and 54 pain-free controls(32 women,22 men).All participants attended a single testing session to assess body composition measures,which included BMI,percentage of body fat(%BFBioimpedance),and skeletal muscle mass(both assessed by bioelectrical impedance analysis),and percentage of body fat(%BFskinfoid)(assessed by skinfold caliper analysis).A one-way univariate analysis of covariance(age and physical activity levels as covariates) was used to compare body composition measures between groups(i.e.,PFP vs.pain-free group;women with PFP vs.pain-free women;men with PFP vs.pain-free men).Results:Women with PFP presented significantly higher BMI,%BFBiompedance,and %BFSkinfold,and lower skeletal muscle mass compared to pain-free women(p≤0.04;effect size:-0.47 to 0.85).Men with PFP and men and women combined had no differences in BMI,%BFBioimpedance,%BFSkinfold,and skeletal muscle mass compared to their respective pain-free groups(p> 0.05).Conclusion:Our findings indicate that BMI and body composition measures should be considered as part of the evaluation and management of people with PFP,especially in women,who have demonstrated higher BMI and body fat and lower skeletal muscle mass compared to pain-free controls.Future studies should not assess body composition measures in a mixed-sex population without distinguishing men participants from women participants.

We evaluated the relationships of body composition and serum adipocytokine levels with progression-free survival(PFS)and overall survival(OS)in metastatic castration-resistant prostate cancer(mCRPC)patients receiving docetaxel.The medical records of mCRPC patients who received docetaxel between January 2011 and December 2015 at Fudan University Shanghai Cancer Center(Shanghai,China)were reviewed.The following body composition parameters were calculated using computed tomography:skeletal muscle index(SMI),visceral adipose tissue index(VATI),and subcutaneous adipose tissue index(SATI).Pretreatment serum adipocytokine levels,including interleukin 6,insulin,leptin,monocyte chemoattractant protein-1,adiponectin,and resistin,were measured using the multiplex bead-based immunoassays.Cox regression and Kaplan–Meier methods were used for survival analyses.Of the 453 mCRPC patients initially identified,105 were included in the analysis.High VATI group patients had longer PFS(median,10 months vs 7 months,P=0.008)and OS(median,24 months vs 15 months,P=0.017),compared with low VATI group patients.SMI and SATI were not significantly associated with PFS or OS.Of the six detected adipocytokines,only leptin was associated with mCRPC prognosis.High leptin group patients had shorter PFS(median,7 months vs 12 months,P=0.0018)and OS(median,17 months vs 22 months,P=0.042),compared with low leptin group patients.Multivariate analysis showed that a high VATI was an independent protective factor for PFS and OS,while a high leptin level was an independent risk factor for PFS and OS.Therefore,VATI and serum leptin levels could provide important information concerning mCRPC prognosis.

Background Recently,beneficial effects of probiotics and/or prebiotics on cardio-metabolic risk factors in adults have been shown.However,existing evidence has not been fully established for pediatric age groups.This study aimed to assess the effect of synbiotic on anthropometric indices and body composition in overweight or obese children and adolescents.Methods This randomized double-blind,placebo-controlled trial was conducted among 60 participants aged 8-18 years with a body mass index(BMI)equal to or higher than the 85th percentile.Participants were randomly divided into two groups that received either a synbiotic capsule containing 6x109 colony forming units(CFU)Lactobacillus coagulans SC-208,6 x 109 CFU Lactobacillus indicus HU36 and fructooligosaccharide as a prebiotic(n=30)or a placebo(n=30)twice a day for eight weeks.Anthropometric indices and body composition were measured at baseline and after the intervention.Results The mean(standard deviation,SD)age was 11.07(2.00)years and 11.23(2.37)years for the placebo and synbiotic groups,respectively(P=0.770).The waist-height ratio(WHtR)decreased significantly at the end of the intervention in comparison with baseline in the synbiotic group(0.54±0.05 vs.0.55±0.05,P=0.05).No significant changes were dem-onstrated in other anthropometric indices or body composition between groups.Conclusions Synbiotic supplementation might be associated with a reduction in WHtR.There were no significant changes in other anthropometric indices or body composition.

The objective of the current work was to examine the relationships between quality of life(QOL)domains in persons with spinal cord injury(SCI)and their levels of weekly leisure-time physical activity(LTPA),anthropometric variables,and body composition variables.This exploratory cross-sectional study consisted of baseline data collected as part of a randomized clinical trial at a VA Medical Center and SCI center.A convenience sample of 36 community-dwelling persons with SCI participated in the current study.Outcome measures included the World Health Organization Quality of Life Short Form(WHOQOL-BREF),Leisure-Time Physical Activity Questionnaire for People with Spinal Cord Injury(LTPAQ-SCI),anthropomorphic measures(waist,hip,and abdominal circumference),and dual-energy x-ray absorptiometry(DXA)to quantify regional and total body composition.Multiple regression models suggested that engagement in LTPA accounted for 35.7%of the variance in physical health QOL,33.5%in psychological QOL,14.2%in social relationships QOL,and 38.2%in environmental QOL.Anthropometric measures accounted for 11.3%,3.1%,12.0%,and 6.7%of the variance in these QOL indices,respectively,and DXA indices accounted for 18.7%,17.5%,27.4%,and 21.9%.Within these models,the number of minutes of heavy LTPA per day uniquely predicted physical health QOL,the number of mild LTPA days per week uniquely predicted psychological QOL,and the amount of mild LTPA per day uniquely predicted environmental QOL.Bivariate analyses also suggested that android and trunk fat,as well as supine waist and abdominal circumferences,were positively associated with social relationships QOL.Encouraging individuals with SCI to engage in LTPA may robustly enhance multiple aspects of QOL while reducing the risk for cardiovascular and metabolic morbidities associated with SCI.Moreover,this may lead to a further understanding of how QOL may impact longitudinal intervention trials.The study protocol and procedures were reviewed and approved by the McGuire VA Research Institutional Rev

Background: An adequate hydration status is critical to ensure efficiency during mental and physical activities.Our goal was to assess the hydration status of a Spanish group of aeronautical military men and to determine the association of hydration status with body composition and anxiety.Methods: A total of 188 men were evaluated through a validated hydration questionnaire, anthropometric and biochemical parameters, and an anxiety questionnaire. Based on these methods, the criteria of hydration were established.Results: Of the total sample, 81% met the hydration criteria(urine color = well hydrated, water balance ≥0 ml, and total water intake/weight ≥35 ml/kg), and 19% did not meet the hydration criteria(urine color = not sufficiently hydrated or dehydrated, water balance body mass index [(26.3±3.1) kg/m;vs.(25.2±2.8) kg/m;], body fat [(22.3±5.6)% vs.(18.3±6.5)%], urine specific gravity, and urine color. Using a logistic binary regression model, hydration status was related significantly with the percentage of body fat(P=0.004), but no relation was found with age, comorbidities, or medications. Furthermore, total water intake/weight was positively correlated with percentage of body water(r=0.357, P=0.000) and negatively with body fat(kg)(r=–0.427, P=0.000), percentage of body fat(r=–0.405, P=0.000), and waist/hip ratio(r=–0.223, P=0.002). Based on a linear regression model, total water intake/weight was related significantly with percentage of body fat(P=0.001) and percentage of body water content(P=0.035). No relation was found, however, with waist/hip ratio, age, comorbidities, or medications.Conclusions: These findings all suggest a relationship between hydration status and body composition but also set the bases for future studies that relat

Background: Early body composition changes, associated with physical inactivity and disease advancement are devastating for patient-related outcomes in predialysis chronic kidney disease (CKD), thus warranting a detailed analysis of body composition beyond conventional measures.Methods: The study included 40 subjects diagnosed with CKD;recruited between January to May 2021. body composition was measured using the multifrequency analyzer, Inbody 770. International Physical Activity Questionnaire-Short Form was used to assess physical activity. Suitable statistical analyses were performed using SPSS 21.0.Results: The mean age of the subjects was 58.68 ± 12.24 years. Sarcopenic obesity was prevalent in 62.5% of the subjects. body mass index under identified obesity by 15% compared to percent body fat, especially in subjects with low muscle mass. The decline in a unit of estimated glomerular filtration rate (eGFR) significantly correlated with a decrease in weight (p = 0.02), body fat mass (p = 0.05), visceral fat area (p = 0.05), and phase angle (p = 0.01) with marginal changes in waist–hip ratio and extracellular water/total body water. The effect of physical activity on skeletal muscle mass was homogeneous between low and moderate levels, but significantly different from high activity level.Conclusion: Changes in fat and fluid compartment were associated with eGFR decline, whereas higher physical activity positively affected body composition.
