Forecasting and validating fat mass ratio models through anthropometric measurements and health-related factors among people with HIV: a cross-sectional investigation.

There is a limited research on predictive models of fat mass ratio (FMR) in people living with human immunodeficiency virus (HIV) (PWH). This study aimed to develop models considering anthropometric and health-related factors to predict and validate FMR in PWH regardless of sex. One hundred and six Brazilian PWH (46.4±9.8 years) were evaluated for body composition using dual-energy X-ray absorptiometry (DXA), body circumference (BC), and skinfold thicknesses (SKs). FMR predictive models were developed using stepwise linear regression, and their agreement with DXA was assessed using Bland-Altman plots. Cross-validation was performed using the predicted residual error sum of squares (PRESS) method. Six FMR estimation models were developed for PWH, with adjusted R2 ranging from 0.43 to 0.72, standard error of the estimate (SEE) from 0.16% to 0.22%, and 95% confidence interval (CI) from 1.03 to 1.15. Model 6, including thigh SK, waist BC, therapy duration, subscapular SK, education years, and abdominal SK, exhibited the highest determination power (R2 adjusted 0.72, SEE 0.16%, and 95% CI: 1.06-1.15). The agreement between DXA-based FMR and predictive models showed minimal bias (-0.03 to +0.04) and narrower limits of agreement, particularly for the top-performing model (-0.33 to +0.30). Model 6 exhibited a high adjusted Q2PRESS (0.70) and low SPRESS (0.17). Our predictive models advance the study of body composition in PWH by consolidating the use of anthropometry for diagnosing and monitoring lipodystrophy regardless of sex.

Longitudinal changes in triceps skinfold thickness and serum albumin during chemotherapy in patients with pancreatic cancer: Gender-based prognostic insights—A prospective cohort study.

e16308 Background: Cachexia, characterized by distinct fat loss and poor nutritional status, is common in patients with pancreatic cancer. This study investigated the association between triceps skinfold thickness(TSF), indicative of body fat, and serum albumin levels, reflecting nutritional status, with overall survival(OS) in patients with pancreatic cancer. Methods: A prospective cohort of 353 patients with pancreatic cancer from April 2018 to June 2021 who received chemotherapy was queried. TSF(mm) and serum albumin(g/dL) were measured at baseline and every three weeks during follow-up. The optimal cutoffs for their six-month changes(six-month value minus initial value) were determined. We performed a landmark analysis of OS six months after the diagnosis of pancreatic cancer and assessed the factors influencing OS. Gender-specific survival analysis was conducted, culminating in the construction of nomograms for risk stratification. Results: Two hundred ninety-two patients survived over six months, with a median follow-up of 40.9 months. Changes in TSF, albumin, and protein levels over six months and initial albumin levels were independently associated with OS. Cancer stage, response to chemotherapy, and six-month serum CA 19-9 levels were also independent factors for OS. Gender-stratified analysis revealed gender-specific prognostic factors: TSF changes over six months£ 0 were associated with reduced OS (hazard ratio [HR], 1.84; 95% confidence interval [CI], 1.14–2.95) in men; initial albumin levels£ 3.5g/dl (HR, 5.73; 95% CI, 2.48–13.21) and albumin changes over six months£ -0.7g/dl (HR, 3.03; 95% CI, 1.51–6.07) were associated with reduced OS in women. Patients were categorized into low-, medium-, and high-risk groups for each gender based on nomogram scores, and increased risk levels were associated with elevated mortality risk. Conclusions: This was the first prospective cohort study to demonstrate that changes in TSF and albumin levels were associated with OS in pancreatic cancer patients undergoing chemotherapy in a gender-dependent manner.

Maternal pre-pregnancy BMI influences the associations between bisphenol and phthalate exposures and maternal weight changes and fat accumulation

BackgroundBisphenols and phthalates are two classes of endocrine-disrupting chemicals (EDCs) thought to influence weight and adiposity. Limited research has investigated their influence on maternal weight changes, and no prior work has examined maternal fat mass. We examined the associations between exposure to these chemicals during pregnancy and multiple maternal weight and fat mass outcomes. MethodsThis study included a sample of 318 women enrolled in a Canadian prospective pregnancy cohort. Second trimester urinary concentrations of 2 bisphenols and 12 phthalate metabolites were quantified. Self-reported and measured maternal weights and measured skinfold thicknesses were used to calculate gestational weight gain, 3-months and 3- to 5-years postpartum weight retention, late pregnancy fat mass gain, total postpartum fat mass loss, and late postpartum fat mass retention. Adjusted robust regressions examined associations between chemicals and outcomes in the entire study population and sub-groups stratified by pre-pregnancy body mass index (BMI). Bayesian kernel machine regression examined chemical mixture effects. ResultsAmong women with underweight or normal pre-pregnancy BMIs, MBzP was negatively associated with weight retention at 3- to 5-years postpartum (B = −0.04, 95%CI: −0.07, −0.01). Among women with overweight or obese pre-pregnancy BMIs, MEHP and MMP were positively associated with weight retention at 3-months and 3- to 5-years postpartum, respectively (B's = 0.12 to 0.63, 95%CIs: 0.02, 1.07). DEHP metabolites and MCNP were positively associated with late pregnancy fat mass gain and late postpartum fat mass retention (B's = 0.04 to 0.18, 95%CIs: 0.001, 0.32). Further, the mixture of EDCs was positively associated with late pregnancy fat mass gain. ConclusionIn this cohort, pre-pregnancy BMI was a key determinant of the associations between second trimester exposure to bisphenols and phthalates and maternal weight changes and fat accumulation. Investigations of underlying physiological mechanisms, windows of susceptibility, and impacts on maternal and infant health are needed.

Triceps skinfold thickness trajectories and the risk of all-cause mortality: A prospective cohort study.

The measurement of triceps skinfold (TSF) thickness serves as a noninvasive metric for evaluating subcutaneous fat distribution. Despite its clinical utility, the TSF thickness trajectories and their correlation with overall mortality have not been thoroughly investigated. To explore TSF thickness trajectories of Chinese adults and to examine their associations with all-cause mortality. This study encompassed a cohort of 14747 adults sourced from the China Health and Nutrition Survey. Latent class trajectory modeling was employed to identify distinct trajectories of TSF thickness. Subjects were classified into subgroups reflective of their respective TSF thickness trajectory. We utilized multivariate Cox regression analyses and mediation examinations to explore the link between TSF thickness trajectory and overall mortality, including contributory factors. Upon adjustment for multiple confounding factors, we discerned that males in the 'Class 2: Thin-stable' and 'Class 3: Thin-moderate' TSF thickness trajectories exhibited a markedly reduced risk of mortality from all causes in comparison to the 'Class 1: Extremely thin' subgroup. In the mediation analyses, the Geriatric Nutritional Risk Index was found to be a partial intermediary in the relationship between TSF thickness trajectories and mortality. For females, a lower TSF thickness pattern was significantly predictive of elevated all-cause mortality risk exclusively within the non-elderly cohort. In males and non-elderly females, lower TSF thickness trajectories are significantly predictive of heightened mortality risk, independent of single-point TSF thickness, body mass index, and waist circumference.

Evaluation of the relationship between dietary energy and protein intakes and anthropometric measurements in hemodialysis patients.

This study evaluated the relationship between dietary energy, and protein (animal and plant based) intakes and anthropometric measurements in maintenance hemodialysis (MHD) patients. Individuals between the ages of 19 to 65 who received MHD treatment for more than 3 months from October 2021 to February 2022 in the state hospitals were included in the study. Body mass index (BMI) (kg/m2) was calculated for each patient, and anthropometric measurements including upper middle arm circumference, triceps skinfold thickness (TST) and hand grip strength (HGS) were carried out. 3-day food records and Subjective Global Assessment (SGA) were used to assess nutritional status of the patients. Of the 51 MHD patients included in the study, 33 (64.7%) were male and 18 (35.3%) were female. The mean age of the patients was 50.37 ± 11.55 years, and length of time on MHD was 39.49 ± 51.68 months. The mean energy intake of female and male MHD patients was 20.01 ± 6.94 and 17.26 ± 6.24 kcal/kg/d, respectively. The mean dietary protein intake of female and male MHD patients were 0.84 ± 0.35 and 0.78 ± 0.30 g/kg/d, respectively. Dry weight (P = .048), BMI (P = .020), TST (P = .013), and HGS (P = .026) of well-nourished and moderately malnourished female MHD patients according to SGA results were found to be lower than in male patients. While the majority of the patients receiving MHD treatment appeared to be well-nourished according to the SGA results, energy and protein intakes obtained from the food records were below the recommended daily dietary intake. These evaluations affected the anthropometric measurements including HGS, BMI, and TST. Therefore, there is a need for more comprehensive clinical studies in which anthropometric measurements, food consumption, biochemical findings and nutritional screening tools are used all together to evaluate nutritional status in MHD patients.

#1530 Studying parenteral nutrition in patients with dialysis stage chronic kidney disease

Abstract Background and Aims Hemodialysis is associated with high rates of morbidity and mortality, as well as poor quality of life. Changes in nutritional status and loss of protein and energy are important indicators of these risks. Maintaining optimal nutritional status in hemodialysis patients is an important but sometimes overlooked aspect of treatment. In some cases, intradialytic parenteral nutrition is possible, but lack of knowledge about the practical aspects of administration is rarely discussed. The purpose of our study was to study the age-related characteristics of the nutritional status in patients with CKD of the dialysis stages who are on parenteral nutrition. Method The study included 40 patients with stage C5 CKD. Glomerular filtration rate (eGFR) was estimated using the CKD-EPI formula (2011) [11]. Anthropometric data were studied: height, weight, body mass index (BMI), mid-thigh circumference and mid-upper arm circumference, as well as laboratory data: urea, creatinine, electrolytes, albumin, total protein, hemoglobin. All patients underwent instrumental research methods: ECG, EchoCG. The patients were divided into 2 groups – with and without PEM. Statistical data processing was carried out according to standard methods using a computer program package. Results Total body water (TBW) (P = 0.026) and triceps skinfold thickness (P < 0.05) were higher in the hemodialysis group. BMI and other anthropometric parameters showed no significant differences between the two groups. Total caloric intake (P < 0.05) and total cholesterol (P < 0.05) were higher in patients with PEM. Intake of other nutrients, including proteins, lipids, microelements and vitamins, did not show significant differences between the two groups. Only 24% of patients were malnourished. Triglyceride levels were higher in non-malnourished patients, but HDL levels were higher in malnourished patients. Some anthropometric indicators were significantly higher in patients not suffering from PEM. It is worth noting that malnourished patients consumed more calories and nutrients, including proteins, plant lipids, animal lipids and carbohydrates. Conclusion Compared with malnutrition patients and non-malnutrition patients, several anthropometric parameters, including subiliac skinfold thickness and MAC, were significantly lower in the malnutrition group. These values can be measured using simple methods and are used as a useful method for assessing malnutrition. Interestingly, patients with malnutrition and lower BMI albumin actually consumed more calories and nutrients from food. This means that malnutrition in dialysis patients is not simply caused by low food intake.

#360 Short-term treatment with medium cut-off dialyzers increases muscle mass with preserved fat tissue in maintenance HD patients

Abstract Background and Aims Protein-energy wasting is a significant complication of maintenance hemodialysis (HD) patients characterized by reduced fat or muscle mass and strength. The combination of non-modifiable general and disease-related factors, such as uremic toxin accumulation and systemic inflammation, is responsible for this condition. Medium cut-off (MCO) membranes are designed to provide clearance of large-middle molecular weight uremic toxins and inflammatory cytokines without causing loss of albumin. This study aimed to investigate the short-term effect of MCO dialyzers on fat tissues and muscle mass. Method We conducted a prospective, single-center cross-over study on maintenance HD patients treated with regular low-flux (LF) dialyzers. Fat tissues were measured with a skinfold caliper and mid-upper arm circumference. Muscle thickness and strength parameters from six different muscle groups were evaluated with ultrasound. The baseline (control) parameters were measured under LF dialyzers, and the measurements were repeated two weeks after switching to MCO dialyzers for the patients ordered by their clinicians according to the clinical indications. Results The median age was 69.5 (50.3,78.8) years, and 60% of the patients were female. Two weeks after switching to MCO, the Kt/Vs, urea reduction ratios, mean serum albumin, dry weight, and body mass index scores were similar. Mean skinfold thickness and mid-upper arm circumference were 15 mm (11,17) and 28mm (27,30) under LF and 16mm (14,19) and 28mm (27,30) under MCO dialyzers (p=0.82 and p=0.27). Rectus abdominis and external oblique muscle groups remained similar. Internal and external oblique muscle thickness were significantly increased (p=0.002 and p=0.001). Mean rectus femoris and gastrocnemius medialis (GKM) thicknesses were 1.19cm (0.99,1.33) and 1.16cm (0.9,1.4) under LF and 1.31cm (1.20, 1.40) and 1.24cm (0.95,1.40) under MCO dialyzers (p=0.002 and p=0.02). Mean GKM fibrile length and pennation angles were 2.4cm (2.2,2.8) and 20o (18,23) under LF and 2.7cm (2.4, 2.9) and 22o (19,24) under MCO dialyzers (p=0.007 and p=0.001). Conclusion Our study showed that MCO dialyzers increase muscle mass with preserved fat tissues in HD patients, short-term follow-up. This favorable effect might be due to the clearance of uremic toxins, which cannot be removed with conventional methods. If long-term studies support our findings, MCO dialyzers would be a milestone for the treatment of sarcopenia in HD patients.

“Secular trends (2001–2020) in physical fitness as a health component in physiotherapy students from Bydgoszcz (Poland)”

The aim of this study was to assess changes in the components of physical fitness that are conducive to the health of young people surveyed between 2001 and 2020. Hypotheses were formulated about an increase in the thickness of skinfolds, especially among women, the deterioration of the results of fitness tests and the lack of conditioning of the examined changes with socioeconomic factors. Every year, physiotherapy students at the Collegium Medicum in Bydgoszcz, Nicolaus Copernicus University in Toruń (Poland) were examined for body height and mass, skinfold thickness, flexibility, static strength, abdominal muscle strength, functional strength and endurance. The results were obtained from 1161 female students and 464 male students. Similar trends were observed for most of the studied characteristics in people of both sexes. In male students, secular trends towards a decrease in the thickness of biceps skinfolds (R2 = 0.455, p = 0.002) and lower leg skinfolds (R2 = 0.314, p = 0.015) were found. In female students, secular trends towards an increase in the body mass (R2 = 0.41, p = 0.003), a decrease in the thickness of skinfolds over the biceps (R2 = 0.477, p = 0.001) and decreased flexibility (R2 = 0.283, p = 0.023) were found. Male sex and the thickness of suprailiac skinfolds were frequent predictors of the, assessed motor abilities and socioeconomic factors did not significantly affect their maintenance. The obtained results, except for a few secular trend examples of the somatic features (male student’s age and calf skinfold, female student’s body mass, male and female student’s biceps skinfold) and flexibility in women, showed their stability and the lack of conditioning by social factors and by the fitness test. Attention to the appropriate level of the observed components is justified, especially in light of the identified trend that showed their deterioration.

Anthropometrics and cancer prognosis: a multicenter cohort study

BackgroundAnthropometric indicators have been shown to be associated with the prognosis of patients with cancer. However, any single anthropometric index has limitation in predicting the prognosis. ObjectivesThis study aimed to observe the predictive role of 7 anthropometric indicators based on body size on the prognosis of patients with cancer. MethodsA principal component analysis (PCA) on 7 anthropometric measurements: height, weight, BMI, hand grip strength (HGS), triceps skinfold thickness (TSF), mid–upper arm circumference (MAC), and calf circumference (CAC) was conducted. Principal components (PCs) were derived from this analysis. Cox regression analysis was used to investigate the association between the prognosis of patients with cancer and the PCs. Subgroups and sensitivity analyses were also conducted. ResultsThrough PCA, 4 distinct PCs were identified, collectively explaining 88.3% of the variance. PC1, primarily characterized by general obesity, exhibited a significant inverse association with risk of cancer-related death (adjusted hazard ratio [HR]: 0.86; 95% confidence interval [CI]: 0.83, 0.88). PC2 (short stature with high TSF) was not significantly associated with cancer prognosis. PC3 (high BMI coupled with low HGS) demonstrated a significant increase with risk of cancer-related death (adjusted HR: 1.08; 95% CI: 1.05, 1.11). PC4 (tall stature with high TSF) exhibited a significant association with increased cancer risk (adjusted HR: 1.05; 95% CI: 1.02, 1.07). These associations varied across different cancer stages. The stability of the results was confirmed through sensitivity analyses. ConclusionsDifferent body sizes are associated with distinct prognostic outcomes in patients with cancer. The impact of BMI on prognosis is influenced by both HGS and subcutaneous fat. This finding may influence the clinical care of cancer and improve the survival of cancer patients.

Impact of Nutrient Intake on Body Composition in Very Low-Birth Weight Infants Following Early Progressive Enteral Feeding.

Preterm infants have increased body adiposity at term-equivalent age and risk of adverse metabolic outcomes. The aim of the study was to define how nutrient intake may impact body composition (BC) of very low-birth weight infants fed with early progressive enteral feeding and standard fortification. Eighty-six infants with <1500 g birth weight were included in the BC study and stratified into extremely preterm (EP) and very preterm (VP) groups. Nutrient intake was calculated during the first 28 days and BC assessed by dual X-ray absorptiometry at discharge and by skinfold thickness at 12 months of corrected age (CA). Total nutrient intake did not differ between the groups. EP infants had a higher fat mass percentage at discharge than VP infants (24.8% vs. 19.4%, p < 0.001); lean mass did not differ. None of the nutrients had any impact on BC of EP infants. Protein intake did not result in a higher lean mass in either group; fat intake was a significant predictor of increased fat mass percentage in VP infants at discharge (p = 0.007) and body adiposity at 12 months of CA (p = 0.021). Nutritional needs may depend on gestational age and routine fortification should be used with caution in more mature infants.

Fetal bisphenol and phthalate exposure and early childhood growth in a New York City birth cohort

BackgroundExposure to endocrine-disrupting chemicals such as bisphenols and phthalates during pregnancy may disrupt fetal developmental programming and influence early-life growth. We hypothesized that prenatal bisphenol and phthalate exposure was associated with alterations in adiposity through 4 years. This associations might change over time. MethodsAmong 1091 mother–child pairs in a New York City birth cohort study, we measured maternal urinary concentrations of bisphenols and phthalates at three time points in pregnancy and child weight, height, and triceps and subscapular skinfold thickness at ages 1, 2, 3, and 4 years. We used linear mixed models to assess associations of prenatal individual and grouped bisphenols and phthalates with overall and time-point-specific adiposity outcomes from birth to 4 years. ResultsWe observed associations of higher maternal urinary second trimester total bisphenol and bisphenol A concentrations in pregnancy and overall child weight between birth and 4 years only (Beta 0.10 (95 % confidence interval 0.04, 0.16) and 0.07 (0.02, 0.12) standard deviation score (SDS) change in weight per natural log increase in exposure), We reported an interaction of the exposures with time, and analysis showed associations of higher pregnancy-averaged mono-(2-carboxymethyl) phthalate with higher child weight at 3 years (0.14 (0.06, 0.22)), and of higher high-molecular-weight phthalate, di-2-ethylhexyl phthalate, mono-(2-ethyl-5-carboxypentyl) phthalate, mono-(2-carboxymethyl) phthalate, and mono-(2-ethylhexyl) phthalate with higher child weight at 4 years (0.16 (0.04, 0.28), 0.15 (0.03, 0.27), 0.19 (0.07, 0.31), 0.16 (0.07, 0.24), 0.11 (0.03, 0.19)). Higher pregnancy-averaged high-molecular-weight phthalate, di-2-ethylhexyl phthalate, mono-(2-ethyl-5-carboxypentyl) phthalate, mono-(2-ethyl-5-hydroxyhexyl) phthalate, and mono-2(ethyl-5-oxohexyl) phthalate concentrations were associated with higher child BMI at 4 years (0.20 (0.05, 0.35), 0.20 (0.05, 0.35), 0.22 (0.06, 0.37), 0.20 (0.05, 0.34), 0.20 (0.05, 0.34)). For skinfold thicknesses, we observed no associations. DiscussionThis study contributes to the evidence suggesting associations of prenatal exposure to bisphenols and high-molecular-weight phthalates on childhood weight and BMI.

Frequencies and predictors of subcutaneous and intraosseous injection with 4 epinephrine autoinjector devices

BackgroundTo prevent anaphylaxis-associated illness, intramuscular epinephrine injection is recommended. Subcutaneous injection may reduce efficacy, and intraosseous injection promotes morbidity. A few studies suggested that commercially available thigh epinephrine autoinjectors (EAIs) may induce subcutaneous/intraosseous injection in some adults. ObjectiveTo estimate the subcutaneous/intraosseous-injection rates of 4 EAIs by comparing their needle lengths with the ultrasound-measured skin-to-muscle depth and skin-to-bone depth of the midthigh of adults with allergic diseases in a cross-sectional study and to determine patient factors that predict subcutaneous EAI injection. MethodsThigh ultrasound was conducted in a convenience-recruited cohort with minimal and maximal compression to estimate the effect of EAI-induced compression. Subcutaneous/intraosseous-injection rates were estimated for Anapen (BioProject), EpiPen (Mylan), Jext (ALK), and Emerade (Medeca). Multivariate analyses for subcutaneous-injection risk were conducted with age, male/female sex, abdominal and thigh circumferences, and upper-arm skinfold thickness. ResultsA total of 68 patients were recruited. Compression thinned the subcutaneous tissue and muscle by 1 and 9 mm, respectively, on average. Projected subcutaneous-injection rates with/without compression were high for Anapen (65%-66%), moderate for EpiPen and Jext (29%-38%), and lowest for Emerade (13%-21%). Compression introduced a small intraosseous-injection risk with Emerade (4%). Female sex predicted subcutaneous injection (odds ratio, 1.3-2.0; all P < .001). Depending on the EAI, 29% to 97% of women and 0% to 41% of men would be injected subcutaneously. Older men were at risk of intraosseous Emerade injection. Obesity-related variables predicted subcutaneous injection poorly. ConclusionAnapen was associated with high subcutaneous-injection rates. EpiPen and Jext were projected to provide intramuscular injection in all men without risk of intraosseous injection. Emerade yielded the lowest subcutaneous-injection rates in women. Compression largely affected the muscle. Trial RegistrationClinicalTrials.gov Identifier: NCT02886468

Using R Programming for Somatoploting

Introduction: Anthropometry is a technique employed to evaluate body dimensions and ratios by examining body length, width, circumference, and skinfold thickness. It is cost-effective, uncomplicated, and easily transportable, and it may be used in diverse industries. Somatotyping is a primary method used to classify the human physique based on three main components: endomorphy, mesomorphy, and ectomorphy. Heath and Carter established and modified the standards of somatotype, which continue to be employed for global measurements. Several software tools have been created for somatoploting, including SAS/GRAPH, Houcine, Orhan, and machine-learning models. Nevertheless, most of these tools are not open-source, resulting in laborious manual enumeration and hindering the accurate representation of differences among groups. A functional, open-source, precise tool is required to categorise somatotypes of extensive sample sizes and illustrate their differences. Method: R programming is a powerful and versatile programme language, particularly popular in statistical computing and graphics. It is widely used in various fields, like biostatistics, bioinformatics, and financial market analysis. R incorporates original programming concepts like object-oriented programming, which users can use transparently. This paper introduces how to use R programming as a tool for somatoploting, introduces the code for somatoploting, inserts x and y data, and executes the program to get a somatochart. It uses anthropometric data of 34 school-going students collected in Shindikurbet, Karnataka, aged between 10 and 12 years, collected through ISAK protocol guidelines to develop somatotypes and further plot them. Result: The paper holistically demonstrates using R programming to plot somatotypes in a 2-D Somatochart. Using this process, the reader can develop high-quality somatocharts in image or PDF formats. Conclusion: This study explores using R programming, an open-source software, for somatoploting and generating somatocharts. This method aids in understanding complex information, fact-explaining, and guiding action in various fields. It offers accessible data processing, analysis, and presentation, making implementing and saving budgets for students, researchers, and institutions easy. Further research could be conducted to make the code easier to use in Excel sheets or mobile applications.

Influence of Kinanthopometric Profile of National Level Male Judo Players of Tamil Nadu on Performance

Introduction: Anthropometric Aspects and Body composition are the crucial factors in explaining human physical status. Anthropometric advantage, a non-modifiable factor, significantly contributed to athletes' success in sports. The present study was studied to find out the relationship between the Kinanthopometric profiles and performance level of National-level male Judo players from Tamil Nadu, India. Method: 30 male Judo players were measured for their anthropometric parameters. Height, weight, circumferences, and skinfold thickness at various sites were measured. Body density was calculated, and body fat % was determined using Siri's Equation. A special Judo fitness test involved throwing partners using the ippon-seoi-nage technique in three periods with heart rate checks, and an index was calculated based on total throws and heart rate values. Results: An average height of 158.1 (± 8.5) cm was observed in the present study whereas that of weight was 63.7 (± 7.3) kg. Judo players were categorized into Endomorphic (30%), Mesomorphic (36.7 %) and Ectomorphic (33.4 %) body type. Mesomorphic players showed good performance, Ectomorphic players showed average performance, and Endomorphic players displayed poor performance when performances were analyzed using the Special Judo Fitness Test. This underscored a potential link between body type and Judo performance. Conclusion: The study concluded that body composition has a high impact on physical fitness and sports performance.

Anthropometric Profile of Elite Male and Female Cadet Taekwondo Competitors

Introduction: Taekwondo has developed into an Olympic sport, which means that a thorough understanding of the main Taekwondo athletes and competitors' characteristics is necessary. This study investigated the fundamental anthropometric measurements of high-level Taekwondo athletes, with a particular focus on disparities between genders. The objective of this study was to assess and contrast the physical attributes of elite Taekwondo athletes, specifically examining the differences between males and females. Methods: A group of 28 highly skilled Taekwondo athletes, consisting of 14 female and 14 male cadets participated in this study. Results: The results showed a significant difference between male and female competitors' anthropometric variables, most notably in skinfold thickness and fat tissue proportion (p≤ 0.01). Conclusion: Accordingly, these data can help taekwondo specialists in the early stages of selection, especially when advanced examinations are impossible. Further studies profiling this group of responders should include more characteristics to help practitioners recognize talents and create training program goals.

Adult obesity diagnostic tool: A narrative review.

Obesity is a complex chronic metabolic disorder characterized by abnormalities in lipid metabolism. Obesity is not only associated with various chronic diseases but also has negative effects on physiological functions such as the cardiovascular, endocrine and immune systems. As a global health problem, the incidence and prevalence of obesity have increased significantly in recent years. Therefore, understanding assessment methods and measurement indicators for obesity is critical for early screening and effective disease control. Current methods for measuring obesity in adult include density calculation, anthropometric measurements, bioelectrical impedance analysis, dual-energy X-ray absorptiometry, computerized imaging, etc. Measurement indicators mainly include weight, hip circumference, waist circumference, neck circumference, skinfold thickness, etc. This paper provides a comprehensive review of the literature to date, summarizes and analyzes various assessment methods and measurement indicators for adult obesity, and provides insights and guidance for the innovation of obesity assessment indicators.

Providing Intradialytic Parenteral Nutrition Therapy Does Not Improve Anthropometric Status in Hemodialysis Patients with Malnutrition

Background: Malnutrition is prevalent in hemodialysis patients and significantly impacts prognosis. It can result from reduced food intake and protein loss during hemodialysis. Nutritional status is determined through anthropometric examinations, which include upper arm circumference (UAC), body mass index (BMI), hand grip strength, bicep, and tricep fold thickness. Laboratory examinations like total cholesterol and Malnutrition Inflammation Score (MIS) or Subjective Global Assessment (SGA) are also used. Intradialytic Parenteral Nutrition (IDPN) is expected to maintain or improve the nutritional status of hemodialysis patients. Objective: This research examines the impact of parenteral nutrition therapy on the anthropometric status of malnourished hemodialysis patients. Methods: This cross-sectional study, a sub-analysis of a larger nutritional therapy study, involved 24 hemodialysis patients experiencing malnutrition based on SGA B and C criteria with 1-10 years of hemodialysis. IDPN therapy was provided, and anthropometric measurements and total cholesterol were taken at baseline and three months after nutritional therapy. Data processing used comparative statistical analysis. Results: The mean age was 45.33 years, with 14 males and 10 females. After 3 months, there were no significant differences in UAC (mean difference = 0.13; p = 0.69), BMI (mean difference = 0.13; p = 0.50), hand grip strength (mean difference = -0.96; p = 0.282), biceps skinfold thickness (mean difference = 0.13; p = 0.69) and triceps (mean difference = 0.59; p = 0.134) or total cholesterol (mean difference = -1.5; p = 0.71). Conclusion: IDPN therapy for 3 months did not improve the anthropometric status of hemodialysis patients with malnutrition.

Tongue Acupuncture to Treat Dysphagia in Patients with Parkinson's Disease: A Randomized Controlled Trial.

Parkinson's disease (PD) is a chronic degenerative disease that lacks specific treatment. The incidence of dysphagia in patients with PD is 35%-82%. Dysphagia not only affects nutritional intake but also leads to pneumonia, even asphyxia. This study explored the efficacy of tongue acupuncture for treating dysphagia in patients with PD. From March 2021 to June 2023, 64 patients with PD-related dysphagia were chosen from Qingdao Central Hospital and the Affiliated Hospital of Qingdao Binhai University, both in Qindao, Shandong, China. The patients were divided into a tongue acupuncture group (n = 32) and a control group (n = 32). The control group was treated with a VitalStim® 5900 Swallowing Disorder Therapeutic Instrument (CA, USA), and the tongue acupuncture group had tongue acupuncture at Juquan (Ex-HN-10) and Haiquan (Ex-HN-11). Swallowing function and nutritional conditions were compared between the 2 groups after all treatments. The total clinical effective rate in the tongue acupuncture group was higher than that of the control group (P < 0.05). The proportion of grade 1 and grade 2 of the 5-scaled Kubota drinking-water test in the tongue acupuncture group was significantly higher than that in the control group (78.13 % versus 31.26 %; P < 0.05), and the proportion of grade 3, grade 4, and grade 5 was significantly lower than that in the control group (21.87 % versus 68.74 %; P < 0.05). After tongue acupuncture, levels of body mass index, upper-arm circumference, triceps skinfold thickness, hemoglobin, serum albumin, and prealbumin were significantly higher than those in the control group (P < 0.05) and the incidence of complications caused by PD was significantly lower than that in the control group (P < 0.05). Treatment of dysphagia in PD by tongue acupuncture significantly improved swallowing function and nutritional level, and decreased the incidence of complications.

The Estimation of Genetic Parameters for Chronic Progressive Lymphedema and Body Traits in the Rhenish German Draught Horse.

Chronic progressive lymphedema (CPL) is a prevalent and progressive disease in Rhenish German draught horses. The objective of our follow-up study was to evaluate the heritability of this disease in Rhenish German draught horses using pedigree-based and genomic relationship matrices. We employed linear and threshold animal models. Models included the random animal effect and effects of breeding association, coat colour, sex, and age within sex, and farm-related factors, on CPL scores. In addition, we estimated heritabilities in models assuming censoring for data when horses were below an age of 1-15 years. The heritabilities of CPL scores across all ages were 0.595 ± 0.131 and 0.482 ± 0.105 in the threshold and linear animal model with pedigree-based relationship matrices, respectively. The restriction of data to horses with a minimum age at examination or accounting for censored data in younger animals showed an increase in heritabilities of CPL scores up to 0.788 ± 0.168 (threshold model) and 0.752 ± 0.153 (linear model) at an age of 7-8 years. Analyses including genomic relationship matrices yielded very similar estimates, but with smaller standard errors than pedigree-based analyses. Heritabilities in threshold models for CPL prevalence (CPL-bin-score) and the number of affected limbs (CPL-bin-sum) were 0.176-0.189 ± 0.061-0.064 and 0.375-0.433 ± 0.164-0.170, respectively. We were able to show moderately to highly positive genetic correlations between the CPL score and cannon bone circumference (0.529-0.825), height at withers (0.338-0.555), and skinfold thickness (0.241-0.517). Using the dichotomous trait for the CPL score and the genomic relationship matrix resulted in corresponding estimates of 0.868, 0.793, and 0.784, respectively. This study showed the great importance of additive genetic variation influencing the expression of chronic progressive lymphedema in Rhenish German draught horses. Therefore, further research is warranted to implement breeding programmes in a small breeding population that exploit the potential of additive genetic differences among animals for reducing the prevalence and severity of lesions of this incurable disease.
