Anthropometric Study of Orbitonasal Proportion and Their Comparisons in Bangladeshi Buddhist Rakhain Ethnic Males and Females

Background: Anthropometric pattern of the orbitonasal proportion varies with no universal normative values. Objective: The purpose of the present study was to evaluate the anthropometric study of orbitonasal proportion and their comparisons in Bangladeshi Buddhist Rakhain Ethnic males and females. Methodology: This cross-sectional study was carried out in the Department of Anatomy, Bangabandhu Sheikh Mujib Medical University (BSMMU), Dhaka, Bangladesh from January 2011 to December 2011 for a period of one (01) year. Adult healthy Bangladeshi Buddhist Rakhain males with the age group of 18 to 30 years were included as study population. Standard of normative facial anthropometric values related to intercanthal distance and nose width. Results: This study shows the inner intercanthal distance (IICD) mean value of males and females as 33.19±2.88 mm and 31.28±2.78 mm, respectively with a statistically significant relationship (P<0.05). The nose width was 41.16 (±3.03) in male and 36.11 (±2.20) in female which was statistically significant (P<0.05). Conclusion: This study shows that intercanthal distance and nose width differs across the adult healthy Bangladeshi Buddhist Rakhain males and females. Gender and ethnicity are two of the main parameters that affect the variation. These findings would be applicable in clinical setup as reference values during surgical planning.

Association of anthropometric parameters with intelligence quotient in early school-aged children: a cross-sectional study in Iran

BackgroundWhile the link between body growth indices in the first three years of life and neurodevelopment is well established, the relationship between these indicators and intelligence levels in later stages is not well understood. This study aimed to investigate the association between various anthropometric indices and Intelligence Quotient in early school-aged children.MethodsThis cross-sectional study recruited healthy students aged 7 to 8 years from four primary schools in Tehran, Iran. Measurements included body weight, height, body mass index, arm circumference, waist circumference, and hip circumference. Intelligence Quotient was assessed using the Raven's Standard Progressive Matrices Test, with scores standardized by age according to the Raven's manual. Separate univariate linear regression analyses evaluated the association between each anthropometric index and children’s Intelligence Quotient scores. Multivariate linear regression analyses were then performed to adjust for potential confounding factors, including the child's sex, age, and parental education levels.ResultsA cohort of 160 children (80 females), with a mean age of 7.5 ± 0.6 years, was included in the study. The participants exhibited the following mean anthropometric values: weight 27.7 ± 6.5 kg, height 1.2 ± 0.1 m, body mass index 17.9 ± 3.4 kg/m2, arm circumference 20.7 ± 2.8 cm, waist circumference 56.4 ± 6.4 cm, and hip circumference 68.1 ± 6.6 cm. Their mean Intelligence Quotient score was 106 ± 16.6. In the univariate analysis, children's weight was not significantly associated with Intelligence Quotient score (P-value = 0.153, β = 0.288 [-0.108, 0.684]), while height was negatively associated (P-value = 0.048, β = -31.685 [-63.142, -0.228]) and body mass index showed a positive association (P-value = 0.001, β = 1.265 [0.524, 2.006]). Abdominal circumference was not significantly associated with Intelligence Quotient (P-value = 0.913, β = 0.051 [-0.870, 0.972]), but both waist circumference (P-value = 0.007, β = 0.542 [0.147, 0.937]) and hip circumference (P-value = 0.013, β = 0.484 [0.102, 0.866]) demonstrated significant positive associations with Intelligence Quotient. However, none of the anthropometric indices maintained statistically significant associations with Intelligence Quotient after adjusting for potential confounders (P-values > 0.05).ConclusionsThis study indicated no strong relationship between various body measurements and intelligence levels in school-aged children after adjusting the analyses for confounders. This suggests that intelligence in these children may be largely shaped by genetic and sociodemographic factors, with minimal influence from physical growth patterns.

Percentile Values of Specific Physical Performances in Tunisian Basketball Players Aged 9 to 21: Considering Maturity Status

Background: Success in basketball is influenced by various factors, including biological maturation. Peak height velocity (PHV) is a key indicator of maturation, playing an important role in assessing the performance of basketball players. This study aimed to analyze the effects of maturational status, chronological age, and gender on anthropometric characteristics and physical performance parameters in Tunisian basketball players and to establish local percentile reference values for physical performance. Methods: A total of 470 basketball players (240 males and 230 females) were categorized into three maturity status groups: pre-PHV (n = 111), circa-PHV (n = 170), and post-PHV (n = 189). Anthropometric and physical fitness parameters were assessed to provide percentile reference values. Results: Our findings revealed significantly higher anthropometric and physical performance values in the post-PHV athletes compared to those in the pre- and circa-PHV groups. Additionally, male athletes outperformed females in most measured variables. Basketball-specific skills appeared to be more dependent on chronological age than on pubertal status. Conclusions: Percentile values were established for both boys and girls, offering valuable references for trainers to quantify and individualize training programs. These findings may assist practitioners in identifying potentially talented basketball players based on their maturation status.

Association Between Anthropometric and Hematological Parameters and the Diagnosis of Intestinal Parasitosis in Low-Income Children.

This study aims to determine the association between anthropometric values and laboratory tests with parasitosis diagnosis and identify diagnostic models for parasitosis without relying on copro-parasitological examinations. Data were collected from 1894 children aged 0-14 who attended a medical center for low-income children in Lima, Peru, between 2021 and 2022. Anthropometric data (BMI, weight, height), laboratory data (red blood cells, hemoglobin, platelets, hematocrit, mean corpuscular volume, mean corpuscular hemoglobin, eosinophils), and parasitological examination results were analyzed. Prevalence ratios for the association between parasitosis and each anthropometric and laboratory variable were estimated using multivariable Poisson regression. Regression models were developed for each type of parasite found, and the diagnostic value was assessed using ROC curves. A high prevalence of parasitosis was identified (41.9%), including Blastocystis hominis (29.1%), Endolimax nana (7.76%), Entamoeba coli (5.97%), Giardia duodenalis (6.44%), and Enterobius vermicularis (1.85%). It was found that the male sex (PRa 1.18), the age group of 2-5 years (PRa 4.83) and >5 years (PRa 4.59), the percentage of eosinophils (PRa 1.02 for every 1% increase), and height/age with -5 SD (PRa 1.34) were associated with a greater risk of parasitosis. Satisfactory values were only shown for diagnostic models associating Enterobius vermicularis and BMI, with a diagnostic value of 70.9% and 70.2% for a BMI < 12 and hematocrit > 29.8%, and BMI < 12 and hemoglobin < 10.6 g/L, respectively. Satisfactory diagnostic value models were only found for parasitosis by Enterobius vermicularis, suggesting the potential for reducing reliance on copro-parasitological exams in resource-limited settings.

Abstract 4127562: Age, Adiposity-Related Anthropometrics, and Clinical Outcomes in Heart Failure with Mildly Reduced or Preserved Ejection Fraction: A Participant-Level Pooled Analysis of Randomized Trials

Background: Age has been shown to modify the population-level association between body mass index (BMI) and mortality. However, whether age modifies the association between adiposity-related anthropometrics and adverse outcomes in heart failure (HF) populations has not been systematically explored. Methods: In this participant-level pooled analysis of five international, multicenter, randomized-controlled trials enrolling adults with HF and either mildly reduced or preserved ejection fraction (HFmrEF/HFpEF), the association between age and adiposity-related anthropometrics (BMI, waist circumference [WC], and waist-to-height ratio [WHtR]) and the primary composite outcome of time-to-first HF hospitalization or cardiovascular (CV) death was evaluated using multivariable adjusted Cox proportional hazards models (stratified by treatment and trial) and restricted cubic splines. Results: Among 21,606 participants in the analysis (mean age, 71±9 years; 49% female; 83% White; mean BMI, 30±6 kg/m 2 ), 5,350 (25%) were aged &lt;65 years, 8,273 (38%) were aged 65-74 years, and 7,983 (37%) were aged ≥75 years at baseline. Older individuals were more likely to be female, have lower BMI and WC, and higher left ventricular ejection fraction. Overall, BMI, WC, and WHtR were steeply and non-linearly associated with the primary outcome ( Figure ). Age, as either a categorical or continuous variable, significantly modified the covariate-adjusted association between all anthropometrics and the primary composite outcome ( P ≤0.001 for all) ( Figure ). A J-shaped relationship, characterized by higher incidence of the primary outcome with lower anthropometric values, was observed only for BMI and was substantially attenuated among younger adults. Irrespective of the anthropometric used, increasing adiposity was most steeply associated with primary events among adults aged &lt;65 years. Conclusions: In this pooled analysis of HFmrEF/HFpEF trials, age was a powerful modifier of the relationship between excess adiposity and HF hospitalization or CV death. An “obesity-survival paradox” – observed only for BMI – was not apparent in younger participants, who exhibited the steepest increase in the rate of clinical events with higher adiposity.

Determining of the relationship between gum phenotype and anthropometric data of the face and gender

Relevance. Diagnosis of the condition of periodontal tissues at the stage of comprehensive treatment planning for a dental patient is an important step in the work of dentists. The presence of difficulties in diagnosing the phenotypic condition of the gums dictates the need to search for additional clinical diagnostic methods that allow determining the phenotype with minimal time and financial costs.Objective. To determine the relationship between anthropometric values of the face (width and height of the face) and gender with the gin-gival phenotype.Materials and methods. During the clinical examinations, an analysis was carried out of the anthropometric data of men and women obtained as a result of photometry, the results of a study of the gingival phenotype by transgingival probing using the De Rouck method and CBCT data (cone beam computed tomography) in patients with their further distribution into groups. A total of 45 people took part in the study, of which 12 were men and 33 were women.Results. Statistical processing of the obtained data showed that for men, the differences between the groups with different phenotypes (thick/ thin) are reliable for the parameter face width. For women with different gum phenotypes (thick and thin), reliable differences were obtained between the groups for the parameters face height and face width. The gum phenotype correlates with the face width (noticeable correlation for all, high for men and women separately); face height (moderate correlation for all, men and women); but does not correlate with the facial index and gender.Conclusion. Thus, the study showed that a combined diagnostic examination of the patient, taking into account gender, facial height and width in women, and facial width in men, can help in the correct assessment of the gingival phenotype.

COMPARATIVE STUDY ON ANTHROPOMETRIC AND MOTOR DIFFERENCES IN U15 BASKETBALL PLAYERS

Basketball is a predominantly aerobic sport during which high-intensity anaerobic actions are performed. In recent years, this characteristic has evolved in terms of demands on the athlete and intensity of the competition, implying an increase in the number and duration of explosive actions. To meet the demands of this sport, good technical, tactical, physical and mental training is required. The research purpose was to determine the anthropometric and motor differences between two male basketball teams from a private club, both playing in the U15 age category. The study included 32 athletes who were divided into two groups. One group was made up of 16 players representing the club’s elite team, and the other group also consisted of 16 players representing the club’s secondary team for this age category. All players were tested in the same sports hall on two different days, during their training for the U15 National Basketball Championship of Romania. Anthropometric and physical characteristics were measured using a test battery with six variables: Height, Weight, Body mass index, 10 m Sprint, Standing long jump, Vertical jump, and Little Marathon. The methods used were: literature review, observation, mathematical statistics, tabular and graphical methods. Differences in anthropometric and physical values between the basketball players of the two teams were determined using the t-Test for independent small samples (Assuming Equal Variances). Our research hypothesis is confirmed, since there are significant anthropometric and motor differences between the players of the two representative club teams, justifying the presence of the elite team in the U15 National Basketball Championship.

Reference values for cerebral and peripheral tissue oximetry in children: A clinical TD-NIRS study.

Current non-invasive near-infrared spectroscopy (NIRS) tissue oximetry suffers from suboptimal reproducibility over probe repositioning, hindering clinical threshold establishment. Time Domain-NIRS (TD-NIRS) offers higher precision but lacks sufficient paediatric data, preventing effective clinical application. We aimed to establish reference ranges for cerebral and mid-upper arm (MUA) tissue haemodynamics in paediatric subjects using TD-NIRS and explore correlations with auxological variables. TD-NIRS measurements were conducted acquiring data from cerebral and MUA regions with the NIRSBOX tissue oximeter. Morphological and clinically relevant information were collected to explore potential correlations with TD-NIRS derived parameters. TD-NIRS assessment was applied in 350 children (8.4 ± 5.0 years). Precision of TD-NIRS was demonstrated with standard deviations of 0.9% (StO2) and 4.2 μM (tHb) for frontotemporal cerebral cortex, and 0.8% (StO2) and 3.7 μM (tHb) for MUA. No user dependency was observed. The trends of values for cerebral and peripheral regions vary differently according to age and auxological parameters. This study reports resting-state optical and haemodynamic values for a healthy paediatric population, providing a foundation for future investigations into clinically relevant deviations in these parameters. Furthermore, correlations with anthropometric and demographic values provide valuable insights for a deeper understanding of tissue haemodynamic evolution in childhood.

The Self-Reported Quality of Sleep and Its Relationship with the Development of Arterial Hypertension: Perspectives from the Tlalpan 2020 Cohort.

Background/Objectives: A well-established association exists between the development of hypertension and sleep quality. The connection between self-reported sleep quality and the onset of hypertension is particularly significant in populations with metabolic deterioration, such as in Mexico. Methods: The Tlalpan 2020 Cohort was analyzed to explore this association. Clinical and anthropometric characteristics, along with the Medical Outcomes Study Sleep Scale (MOS-SS), were compared between participants who developed hypertension and those who did not over a follow-up period of 30.8 months. The potential role of poor sleep quality in the development of hypertension was assessed. Results: Among 1520 participants, 12% developed hypertension. These individuals had higher anthropometric and laboratory values and reported poorer sleep quality. An elevated sleep problems index was associated with a 50% higher relative risk of developing hypertension (OR: 1.5; 95% CI: 1.087 to 2.069). Additionally, self-reported snoring was associated with hypertension onset (36.3 vs. 43.3; p = 0.019). Conclusions: Poor sleep quality and respiratory disturbances during sleep increase the risk of developing hypertension. Furthermore, hypertension was associated with snoring, highlighting the importance of early interventions to improve sleep quality.

O44 LOW ADHERENCE TO HYPERTENSION MANAGEMENT IN THE COLOMBIAN COMMUNITY IMPLEMENTATION RE-HOPE STUDY

Background and objective: Uncontrolled hypertension is a leading cause of death worldwide, and it's associated with a high socioeconomic burden. Demographic, social, behavioral, and health system-related factors contribute to low adherence to hypertension management. Recognizing adherence rates is a mainstay for improving hypertension control. This study examined the level of adherence to hypertension management and control in the participants belonging to the implementation, integration, and institutionalization of a community-based care strategy to reduce the risk of cardiovascular disease in Santander (ReHOPE) study. Methods This cross-sectional analysis was conducted in 12 municipalities of Santander, Colombia, from May to December 2023. Participants over 18 with hypertension, not in a cardiovascular risk program, were included. Data were collected door-to-door by trained community health providers using standardized questionnaires for socio-demographic information, medication use, lifestyle details, and hypertension knowledge. Physical exams provided anthropometric and blood pressure values. Medication adherence was assessed with the Morisky 4-item scale. Continuous variables are presented as central tendency measures, and categorical variables as frequencies and proportions. Analysis was performed using R software. Results: A total of 2,617 participants were included. The mean age was 65.09 (SD 12.09), and 64.3% were women. The mean systolic blood pressure was 133.94 mmHg (SD 16.53). The median waist-to-hip ratio (WHR) was 0.96 (IQR 0.92-1.00) in men and 0.91 (IQR 0.87-0.96) in women. Among participants, 33.9% had uncontrolled hypertension, 28.5% were not aware of their condition, and 69.2% reported no physical activity. High WHR was found in 84.8% of the participants. Antihypertensive monotherapy use was reported in half of the participants (53.8%). The most frequently used pharmacological group was angiotensin-converting enzyme inhibitors (81.8%). Hypertension control was observed in 66.1%, and 12.6% had high adherence. Conclusions: Low medication adherence was observed, only 12.6% of participants reported high adherence and nearly 40% had uncontrolled hypertension. Additionally, nearly 30% were undetected by the healthcare system. Thus, improving medication adherence and healthcare strategies is essential to enhance health outcomes.

Respiratory, cardio-metabolic and neurodevelopmental long-term outcomes of moderate to late preterm birth: not just a near term-population. A follow-up study.

Moderate-to-late preterm infants constitute the majority within the preterm infant population. Most research on preterm infants has focused on very preterm children, often treating moderate-to-late preterm infants as similar to full-term infants. Our objective was to compare clinical, respiratory, cardio-metabolic and neurodevelopmental outcomes in adolescents aged 12-15 years born moderate and late preterm with a control group of the same age born full-term. Observational cross-sectional study, comparing moderate-to-late preterm (32-36+6 weeks' gestational age) with full-term adolescents (37-41+6 weeks' gestational age; 75 each group). Perinatal and neonatal history were collected as well as data on respiratory evolution (ISAAC questionnaire for asthma symptoms for adolescents 13-14 years), anthropometric values, learning difficulties, behavioral test (screening questionnaire for high-performance autism spectrum disorder and evaluation test for attention deficit hyperactivity disorder), skin prick test, pulmonary function test, echocardiogram and blood pressure. A blood test with metabolic profile was conducted. Moderate-to-late preterm adolescents had more current asthma [p = 0.008, OR3 (95% CI 1.26-7.14)] and longer duration of combined treatments to control asthma (inhaled corticosteroids and anti-leukotrienes; p = 0.048). Forced vital capacity <80% was detected more often in moderate-to-late preterm patients (p = 0.013). When assessing right ventricle, moderate-to-late preterm adolescents showed better tricuspid annular plane systolic excursion z-score (p = 0.003), shortening fraction (p < 0.001) and E/A ratio z-score (p = 0.002). Regarding left ventricular assessment, moderate-to-late preterm group had smaller ventricle diastolic diameter (p = 0.04) and lower posterior wall z-score values (p = 0.037). They also showed a better S'wave z-score (p = 0.027), E wave (p = 0.005), E/A ratio (p = 0.003) and a higher septal myocardial performance index z-score (p = 0.025). Moderate-to-late preterm adolescents presented lower weight z-score (p = 0.039), body mass index z-score (p = 0.013), Waterlow weight index (p = 0.006) and higher undernutrition index [p = 0.04; OR 1.4 (95% CI 1-1.9)]. Although there were no differences in neurodevelopmental survey or behavioral tests. Our findings underscore the importance of extended follow-up for this predominant group of premature infants to identify potential respiratory, cardiac and anthropometric issues that may emerge in the future.

Ocular biometry and anthropometric measurements in young myopes – A case–control study

Background: The prevalence of myopia in the 5–15-year age group in India has been 7.5% over the past four decades. While ocular growth and physical growth occur simultaneously during early life, the existence of a common regulatory system for both is still debated. Aims and Objectives: This study aims to analyze the ocular biometry and anthropometric values of young myopes and emmetropes aged 18–25 years. Materials and Methods: This case–control study involved a sample size of 86 participants. Corneal curvature was measured using keratometry, while A-scan ultrasonography was utilized to measure axial length, lens thickness, anterior chamber depth, and vitreous chamber depth. Results: The results indicated that there were no significant differences in ocular biometry and anthropometric values between the case and control groups, except for corneal thickness and axial length. The mean corneal thickness was found to be 549.64 μm in the case group and 566.05 μm in the control group, while the mean axial length was 24.70 mm in the case group and 23.41 mm in the control group. An increase in height was correlated with longer axial length in myopes. Conclusion: There was no difference in anthropometry and ocular biometry in emmetropes and myopes in the age group of 18–25 years of age. Myopes tend to have thinner corneas, which should be taken into consideration before performing refractive surgeries. The presence of thin corneas in individuals with myopia can result in inaccurately low measurements of intraocular pressure, potentially hampering the early detection of glaucoma within this high-risk demographic.

Nutritional parameters following first episode of pediatric acute pancreatitis

Acute pancreatitis (AP) carries the risk of subsequent nutritional deficiencies. The prevalence of these deficiencies following a single episode of AP in children is unknown. We aimed to determine prevalence of anthropometric and laboratory-based measures of nutritional status in children following their first (index) admission for AP. Prospective observational cohort study of patients ≤21 years of age with first episode of confirmed AP. Anthropometric and laboratory values were obtained at time of AP onset and at follow up time points of 3 and 12 months (m) post AP. AP attack was classified as either: mild, moderately severe or severe (which were combined in one group (SAP)). 181 patients met criteria and were followed prospectively with 52% male, a median age of 13.7 years (IQR 9.4-16.0) and median Body Mass Index (BMI) Z-score of 0.6 (IQR -0.5, 1.6). Most patients had mild AP (140, 77%), with 23% meeting criteria for moderate or severe (41/181). 6 (3%) had diabetes mellitus (DM) predating AP and were excluded from further analysis. BMI Z-score remained stable during the follow up period. 13% of patients developed pre-DM or DM at 3m or 12m. Nearly one third of patients had low ferritin at 3m (29%) or 12m (29%). At 12m, 8% of patients had Vitamin A deficiency. 6% of patients had low Vitamin E levels at 3m and 5% at 12m. Over half of patients at both 3m and 12m had 25 OH Vitamin D insufficiency or deficiency (56% and 56%). Prolonged International Normalized Ratio (INR) (>1.3) was seen in 9% of patients at 12m. Very low albumin (<3.5g/dL) was found in 24% of patients at 3m and 18% at 12m (Table1). Patients with very low albumin at 3m were younger (median 10.7 vs. 14.2 years, p=0.04), however sex, BMI Z-score and AP severity were not associated with albumin level. Although BMI Z-score did not differ between the groups, those with SAP had a significant decrease in BMI Z-score from first attack compared to mild AP at 3m (-0.4 vs. 0.0, p=0.0002, Figure2). At 3m, Vitamin E deficiency in SAP versus mild AP was found in 20% vs 2% (p=0.04) and SAP had a lower median hematocrit (35.8 vs. 37.6, p=0.046). There were no other laboratory significant differences at 3m in mild versus SAP groups. At 12m, those with SAP were more likely to have pre-DM or DM compared to mild AP (31% vs. 7%, p=0.002). No other significant laboratory differences occurred at 12m. After the first AP attack patients experience nutritional deficiencies, including ferritin, all fat-soluble vitamins, and low albumin. SAP is associated with a decrease in BMI Z-score, increased prevalence of vitamin E deficiency at 3m, and an increase in pre-diabetes and diabetes at 12m. Serial monitoring of vitamin and mineral values post AP is warranted and further prospective studies are needed.

BODYFAT: a new calculator to determine the risk of being overweight validated in Spanish children between 11 and 17 years of age

The assessment of body fat of children in primary care requires consideration of the dynamic changes in height, weight, lean mass, and fat mass during childhood growth. To achieve this, we aim to develop a predictive equation based on anthropometric values, with optimal diagnostic utility. This is a cross-sectional observational study, involving schoolgoers aged 11–17 years in the Vigo metropolitan area. Out of 10,747 individuals, 577 were randomly recruited. Variables: age, sex, ethnicity/country of origin, weight, height, 8 skinfolds, 3 diameters, 7 perimeters, and 85% percentile of body fat mass as the gold standard. Generalized additive regression was selected by cross-validation and compared using receiver operating characteristic curves (ROC curves). Sensitivity, specificity, positive and negative predictive values, true positive and true negative values, false positive and false negative values, accuracy, and positive and negative likelihood ratios were calculated. Two models were identified. The optimal model includes sex, weight, height, leg perimeter, and arm perimeter, with sensitivity of 0.93 (0.83–1.00), specificity of 0.91 (0.83–0.96), accuracy of 0.91 (0.84–0.96), and area under the curve (AUC) of 0.957 (0.928–0.986). The second model includes sex, age, and body mass index, with sensitivity of 0.93 (0.81–1.00), specificity of 0.90 (0.80–0.97), accuracy of 0.90 (0.82–0.96), and an AUC of 0.944 (0.903–0.984).Conclusion: Two predictive models, with the 85th percentile of fat mass as the gold standard, built with basic anthropometric measures, show very high diagnostic utility parameters. Their calculation is facilitated by a complementary online calculator.What is Known:• In routine clinical practice, mainly in primary care, BMI is used to determine overweight and obesity. This index has its weaknesses in the assessment of children.What is New:• We provide a calculator whose validated algorithm, through the determination of fat mass by impedanciometry, makes it possible to determine the risk of overweight and obesity in the community setting, through anthropometric measurements, providing a new practical, accessible and reliable model that improves the classification of overweight and obesity in children with respect to that obtained by determining BMI.

Role of dietary intervention on sugar-sweetened beverages, fruit juices and milk consumption among obese children/adolescents

The increase in childhood obesity is one of the biggest public health problems of the 21st century. Among the contributing dietary factors is the high consumption of sugar-sweetened beverages (SSB) and sweetened fruit juices (SFJ). On the other hand, regular consumption of milk and dairy products has decreased in many countries over the years, although research has shown an inverse association between dairy consumption and obesity. The aim of this study was to determine the effects of a dietary intervention within a multidisciplinary structured programme on reducing the consumption of SSB and SFJ and simultaneously increasing the consumption of milk and diary products in obese children/adolescents. The study included 100 participants of both sexes who had been diagnosed with obesity and participated in a five-day multidisciplinary structured programme focused on dietary intrevention. Standard anthropometric measurements and a validated questionnaire were used during the study. The mean age of the participants was 12.61±1.90 years, body mass index (BMI) was 98.38±1.26 percentiles; mean consumption of SSB was 1.68 ± 2.89 dL; SFJ was 3.72±5.09 dL and milk and dairy products was 3.10±2.35 dL per day at the start of the intervention. After the five-day programme, patients were reeducated once a month for the first six months, then every two months for up to 24 months. After 24 months, a significant decrease in SSB and SFJ intake (p&lt;0.001) and an increase in milk and dairy products intake (p=0.002) were observed. The percentiles of the BMI also decreased after 24 months (p&lt;0.001). The dietary intervention had a positive effect on the anthropometric values and the change in the dietary habits of the participants, with a focus on the consumption of milk and dairy products.

Predicting mortality within 1 year of ART initiation in children and adolescents living with HIV in sub-Saharan Africa: a retrospective observational cohort study

Differentiated service delivery (DSD) for children and adolescents living with HIV can improve targeted resource use. We derived a mortality prediction score to guide clinical decision making for children and adolescents living with HIV. Data for this retrospective observational cohort study were evaluated for all children and adolescents living with HIV and initiating antiretroviral therapy (ART); aged 0-19 years; and enrolled at Baylor clinics in Eswatini, Malawi, Lesotho, Tanzania, and Uganda between 2005 and 2020. Data for clinical prediction, including anthropometric values, physical examination, ART, WHO stage, and laboratory tests were captured at ART initiation. Backward stepwise variable selection and logistic regression were performed to develop predictive models for mortality within 1 year of ART initiation. Probabilities of mortality were generated, compared with true outcomes, internally validated, and evaluated against WHO advanced HIV criteria. The study population included 16 958 children and adolescents living with HIV and initiated on ART between May 18, 2005, and Dec 18, 2020. Predictive variables for the most accurate model included: age, CD4 percentage, white blood cell count, haemoglobin concentration, platelet count, and BMI Z score as continuous variables, and WHO clinical stage and oedema, abnormal muscle tone and respiratory distress on examination as categorical variables. The area under the curve (AUC) of the predictive model was 0·851 (95% CI 0·839-0·863) in the training set and 0·822 (0·800-0·845) in the test set, compared with 0·606 (0·595-0·617) for the WHO advanced HIV criteria (p<0·0001). This study evaluated a large, multinational population to derive a mortality prediction tool for children and adolescents living with HIV. The model more accurately predicted clinical outcomes than the WHO advanced HIV criteria and has the potential to improve DSD for children and adolescents living with HIV in high-burden settings.

The impact of the obesity onset on the inflammatory and glycemic profile of women with severe obesity

The stage of life at the onset of obesity is an important factor in assessing inflammatory state and cardiometabolic risk. This study aimed to evaluate the relationship between the obesity onset and the inflammatory profile in women with severe obesity. Public hospital, Brazil. Forty-eight women with severe obesity (20-59 yr old) were evaluated according to weight, height, neck circumference (NC), waist circumference (WC), and hip circumference, as well blood metabolic and inflammatory parameters. The participants were grouped according to obesity onset stage of life (early group: ≤19 yr; late group: >19 yr). The demographic means of the participants were: age of 39.7 years, weight of 122.7 kg and body mass index (BMI) of 48.4 kg/m2. The late group presented significantly higher values of leptin (lep)/adiponectin (adipo) ratio and homeostatic model assessment for insulin resistance (HOMA-IR) than the early group. The late group also had a lower adipo/lep ratio. Moreover, the late group showed correlations between the lep/adipo ratio and BMI (r = .460, P = .021), NC (r = .478, P = .016), and WC (r = .535, P = .006). Adipo was also correlated with NC (r = -.418, P = .038), WC (r = -.437, P = .029), and glycated hemoglobin (HbA1C) (r = -.485, P = .019). By contrast, in the early group, the lep/adipo ratio showed correlations with insulin (r = .647, P = .004) and HOMA-B (r = .564, P = .015). The inflammatory profile is correlated with anthropometric values in women with late-onset obesity. Inflammatory markers seemed to correlate with the glycemic profile in women with early-onset obesity. Furthermore, inflammation was higher in women with late-onset obesity compared to those with early-onset obesity.

Normative Standards for Isokinetic and Anthropometric Classifications of University-Level Netball Players.

The purpose of the study was to develop normative ranges and standards for knee and shoulder isokinetic and anthropometric values. These standards can be qualitatively interpreted and allow practitioners to classify isokinetic and anthropometric values more objectively for university-level netball players. Posttest only observational study design. All players were only evaluated once during the in-season to generate normative ranges. A total of 51 female players volunteered. Participants were evaluated on an isokinetic dynamometer at 60° per second to obtain knee-extensor and knee-flexor values as well as shoulder-flexor and shoulder-extensor values. A total of 16 anthropometric variables were collected including stature, body mass, 8 skinfolds, and 6 circumferences. Between-group differences were calculated to determine whether playing level was a differentiating factor in data. Normative standards were developed for isokinetic parameters associated with the knee and shoulder joints as well as skinfolds and circumference measures. No statistically significant between-group differences were evident (χ2Kruskal-Wallis[2] = 3.96, P = .140). These standards can be used by coaches and practitioners to set attainable goals for individual players or those from secondary leagues, classify individual and team-based performances, and facilitate decision-making processes.

Clinical Profile and Efficacy of Long-Acting Octreotide in Hyperinsulinemic Hypoglycaemia.

Hyperinsulinemic hypoglycaemia (HH) is characterised by unregulated insulin secretion, leading to persistent non-ketotic hypoglycaemia with a lack of alternate fuel that induces a severe risk for brain damage and neurodevelopmental abnormalities. Octreotide, a somatostatin analogue, has been effectively administered as subcutaneous injections or depot preparations in diazoxide-unresponsive HH. Children and infants with HH receiving short-acting octreotide injections were included. Anthropometric values, hypoglycaemic episodes, HbA1C, and side effects were noted from the records and were followed up for 12 months. Informed written consent was obtained from the parents before administration of a single dose of LAR (long-acting octreotide). Based on home-based glucose monitoring (HBGM), the dosage of LAR was modified, and short-acting octreotide was eventually withdrawn. The patients shared the injection's cost for cost-effectiveness. HH affects the quality of life (QoL) if not diagnosed and controlled adequately. A QoL questionnaire was given before starting LAR and after 6 months of receiving LAR, and the changes were noted accordingly. Twenty-two patients were diagnosed with HH, of which 11 infants and children were included in the study. Mutations were identified in 7 (63.63%) children. Daily octreotide could be tapered and stopped with the addition of sirolimus in one patient with an increasing dose of LAR to maintain euglycaemia. The hypoglycaemic episodes decreased with increasing dose of LAR with a decrease in the severity. Eight (72.7%) patients showed an improved lifestyle on LAR quantified through a QoL questionnaire. LAR was found effective in reducing hypoglycaemic episodes with no adverse effects. The patient's parent's satisfaction was higher. Given its high cost, this trial achieved cost-effectiveness by sharing a single sitting of LAR injection.
