Association between Neck Circumference and Asymptomatic Hyperuricemia in Nearly Healthy Adults: A Review of 2019-2020 Cross-Sectional Korean Nationwide Data.

Neck circumference (NC) measurement has been recently developed as a simple and time-saving anthropometric method for predicting cardiovascular risk. Asymptomatic hyperuricemia is known as one of the cardiovascular risk factors. This study investigated the association between NC and asymptomatic hyperuricemia among the general population of Korea. This cross-sectional study examined data from 7,629 participants in the 2019-2020 Korea National Health and Nutrition Examination Survey. Multivariable logistic regression analysis was used to identify the factors associated with hyperuricemia. Approximately 10% of participants corresponded to hyperuricemia group who were likely to be male, have more comorbidities, poorer habits, and larger NC. Multivariable regression analysis revealed that NC was significantly associated with hyperuricemia in women (OR 1.17; 95% CI 1.06-1.30), but not in men (OR 1.04; 95% CI 0.96-1.12). A large NC is independently correlated with hyperuricemia among Korean women.

Risk Factors of Ischemic Heart Disease and Risk-Related Awareness in University Students

Objective: Ischemic heart disease (IHD) is the most fatal disease in Turkey. The present study attempted to explore IHD risk factors and risk-related awareness among university students. Materials and Methods: We took the height, weight, waist circumference, and blood pressure measurements of 786 university students and tried to identify their IHD risk factors and risk-related awareness through a survey. The study was carried out on a public university campus over three weekends in October 2022. Results: The findings showed that the most common modifiable IHD risk factors were poor physical activity (48.9%), smoking (30.5%), and overweight/obesity (21.5%) in our sample aged 18-35 years. Yet, the most prevalent non-modifiable risk factor was found to be familial chronic diseases (29.9%). Besides, the participants were found to have poor knowledge of IHD risk factors (8.9±2.5). Our other remarkable finding demonstrated that the male students’ knowledge of CVD was poorer than their female counterparts, although the male gender is a non-modifiable CVD risk factor. Conclusion: Participants with a relatively high level of education, interestingly, had poor knowledge and risk awareness of IHD despite bearing a higher rate of IHD risk factors.

Shedding light on night-time erections: Determining the feasibility of nocturnal erection detection with penile transdermal light reflection of haemoglobin.

Utilizing penile saturation and temperature measurements presents a promising avenue for the development of an innovative sensor system aimed at nocturnal erection detection. This study aims to determine the feasibility of erection detection with light reflection of haemoglobin (LRH), as a precursor for penile saturation measurements, as well as penile temperature by comparison with simultaneous overnight RigiScan measurements. This is a proof-of-concept observational study on 10 healthy volunteers with a cross sectional design. A penile transdermal haemoglobin and temperature sensor was developed to measure penile LRH through real-time monitoring with receiving photodiodes and emitting light-emitting diode (LED). Besides statistical analysis on LRH, temperature and RigiScan data, a visual assessment was done to determine detectability of changes in the LRH and temperature course during the RigiScan-annotated erections. A total of 40 nocturnal erections from 10 healthy volunteers were annotated with the RigiScan. The LRH values significantly increase during a nocturnal erection (p < 0.01) and penile temperature (p < 0.01). The largest elevation of temperature was seen in the last erection, with an increase of 0.94°C. The corrected temperature shows an increase of 1.29°C in the last erection. Furthermore, visual detectability was feasible for 80% of the erections with LRH values and 90% with the temperature output. Penile LRH and temperature have the potential to serve as an alternative methodology for nocturnal erection detection compared with the currently applied circumference and rigidity measurements. This is an important step in the development of a patient-friendly and modernized tool for erectile dysfunction diagnostics. An improved sensor should be developed to allow for calculation of saturation percentage from LRH values. In combination with penile temperature measurements, this allows for conduction of further validity studies to work towards translation into clinical practice for non-invasive ED diagnostics.

Fetal Gestational Age Prediction in Brain Magnetic Resonance Imaging Using Artificial Intelligence: A Comparative Study of Three Biometric Techniques

Accurately predicting a fetus’s gestational age (GA) is crucial in prenatal care. This study aimed to develop an artificial intelligence (AI) model to predict GA using biometric measurements from fetal brain magnetic resonance imaging (MRI). We assessed the significance of using different reference standards for interpreting GA predictions. Measurements of biparietal diameter (BPD), fronto-occipital diameter (FOD), and head circumference (HC) were obtained from 52 normal fetal MRI cases from Rush University. Both manual and AI-based methods were utilized, and comparisons were made using three reference standards (Garel, Freq, and Bio). The AI model showed a strong correlation with manual measurements, particularly for HC, which exhibited the highest correlation with actual values. Differences between GA predictions and picture archiving and communication system (PACS) records varied by reference, ranging from 0.47 to 2.17 weeks for BPD, 0.46 to 2.26 weeks for FOD, and 0.75 to 1.74 weeks for HC. Pearson correlation coefficients between PACS records and GA predictions exceeded 0.97 across all references. In conclusion, the AI model demonstrated high accuracy in predicting GA from fetal brain MRI measurements. This approach offers improved accuracy and convenience over manual methods, highlighting the potential of AI in enhancing prenatal care through precise GA estimation.

Accurate Prediction of Three-Dimensional Humanoid Avatars for Anthropometric Modeling.

To evaluate the hypothesis that anthropometric dimensions derived from a person's manifold-regression predicted three-dimensional (3D) humanoid avatar are accurate when compared to their actual circumference, volume, and surface area measurements acquired with a ground-truth 3D optical imaging method. Avatars predicted using this approach, if accurate with respect to anthropometric dimensions, can serve multiple purposes including patient metabolic disease risk stratification in clinical settings. Manifold regression 3D avatar prediction equations were developed on a sample of 570 adults who completed 3D optical scans, dual-energy X-ray absorptiometry (DXA), and bioimpedance analysis (BIA) evaluations. A new prospective sample of 84 adults had ground-truth measurements of 6 body circumferences, 7 volumes, and 7 surface areas with a 20-camera 3D reference scanner. 3D humanoid avatars were generated on these participants with manifold regression including age, weight, height, DXA %fat, and BIA impedances as potential predictor variables. Ground-truth and predicted avatar anthropometric dimensions were quantified with the same software. Following exploratory studies, one manifold prediction model was moved forward for presentation that included age, weight, height, and %fat as covariates. Predicted and ground-truth avatars had similar visual appearances; correlations between predicted and ground-truth anthropometric estimates were all high (R2s, 0.75-0.99; all p < 0.001) with non-significant mean differences except for arm circumferences (%D ~ 5%; p < 0.05). Concordance correlation coefficients ranged from 0.80-0.99 and small but significant bias (p < 0.05 - 0.01) was present with Bland-Altman plots in 13 of 20 total anthropometric measurements. The mean waist to hip circumference ratio predicted by manifold regression was non-significantly different from ground-truth scanner measurements. 3D avatars predicted from demographic, physical, and other accessible characteristics can produce body representations with accurate anthropometric dimensions without a 3D scanner. Combining manifold regression algorithms into established body composition methods such as DXA, BIA, and other accessible methods provides new research and clinical opportunities.

Prevalence and Quality of Life in Patients with Lymphoedema following Axillary Clearance for Breast and Cutaneous Malignancies

Lymphoedema is a potential adversity following axillary clearance, which is frequently performed in the setting of surgery for breast cancer or cutaneous malignancies of the upper limb. Often underestimated, lymphoedema can lead to debilitating symptoms which may decrease overall health-related quality of life. A retrospective cohort study was undertaken on 73 patients who underwent axillary clearance for breast and cutaneous malignancies from 2011 to 2021 at a tertiary centre in Melbourne, Australia. Bilateral upper limb circumference measurement was used to identify the prevalence of lymphoedema in this population. The lymphoedema quality of life (LYMQOL) questionnaire was used to assess the patient’s quality of life. Of 73 patients, 42 (58%) had lymphoedema; 33 (45%) were clinically detected as part of the study, and 9 were diagnosed with lymphoedema prior to our study. Patients with lymphoedema (n = 42) reported worse scores in all LYMQOL domains and the overall quality of life, but only the ‘appearance’ domain showed statistically significant differences in our cohort. These results demonstrate a substantial post-axillary clearance lymphoedema prevalence, without significant impacts on quality of life.

The gut-pancreas axis: investigating the relationship between microbiota metabolites and pancreatic steatosis.

The prevalence of pancreatic steatosis has increased and it has been linked to the rising prevalence of metabolic syndrome. Metabolic syndrome is known to have a strong connection with changes in intestinal microbiota. The aim of this study was to explore the relationship between pancreatic steatosis and the levels of trimethylamine N-oxide (TMAO) and butyrate. In this study, 136 individuals were randomly selected from outpatient clinics at Firat University Hospital. The study evaluated their demographic characteristics, anthropometric measurements, and biochemical parameters. The presence of pancreatic steatosis was assessed using abdominal ultrasonography. Additionally, the levels of TMAO and butyrate were measured. The mean age of individuals in the study was 44.5 ± 14.6. 84 of the subjects were females. Using the waist circumference, 61 were considered obese and 34 overweight. The detection rate of pancreatic steatosis was found to be 70.6%. The study found that individuals with steatosis had higher average age, presence of hepatic steatosis, BMI, waist circumference measurements, and presence of metabolic syndrome than those without steatosis. A significantly higher butyrate level was detected in those without steatosis (p = 0.001). TMAO levels were slightly higher in patients without steatosis than in those with steatosis; however, this was insignificant. Pancreatic steatosis is highly associated with alterations in levels of microbiota metabolites, indicating a potential role of these metabolites in the pathogenesis of the disease and subsequent therapeutic targets. Several other factors, such as age, hepatic steatosis, diabetes, and waist circumference, have also been identified as potential predictors of pancreatic steatosis.

Effects of a physical exercise programme on bodyweight, body condition score and chest, abdominal and thigh circumferences in dogs

BackgroundResearch on the effects of physical exercise on canine body composition is limited. The aim of this study was to investigate the effects of a physical exercise programme on bodyweight, body condition score (BCS) and chest, abdominal and thigh circumferences in dogs. Twenty-one healthy dogs of different breeds exercised together with their owners during an eight-week programme consisting of jogging and strength exercises. Standardised measurements were performed in triplicates with a measuring tape on standing dogs. Chest circumference was measured at three anatomical locations, abdomen at two and thigh at one. Data on bodyweight, BCS (9-point scale) and circumferences were analysed with mixed model repeated measures analyses to evaluate changes after the programme and effects of target distance.ResultsSeven dog owners choose a target distance of 2 km and 14 owners choose 5–10 km. Mean BCS decreased (P = 0.007) after the programme (5.1 ± 0.9 vs. 4.7 ± 0.6) but there was no effect of target distance. Almost all chest and abdominal circumference measurements decreased (P ≤ 0.007) with the 2 km group driving the reduction in chest circumference and the 5–10 km group driving the reduction in abdominal circumference. In contrast, thigh circumference (28.8 ± 0.4 vs. 30.2 ± 0.4) increased (P = 0.007) while bodyweight was maintained. There were positive correlations between BCS and abdominal/chest ratios before and after the programme (Pearson correlation; R square ≤ 0.43, P ≤ 0.0012) but the mean ratio remained constant.ConclusionsResults indicated a redistribution between total body fat and muscle mass in body composition of normal weight to slightly overweight dogs after the physical exercise programme. The use of bodyweight alone was not a reliable evaluation method to complement the BCS assessment. However, repeated measurements of chest, abdominal and thigh circumference might aid in the assessment of body composition in dogs performing physical exercise. Further research should include a control group and objective evaluations of total body fat and lean mass, in order to investigate the effectiveness of physical exercise as a freestanding method for decreasing BCS and increasing muscle mass in overweight dogs.

Feasibility of implementing a remote system for lymphoedema conservative therapy: a case study.

Poor access to lymphoedema specialists and communication between them and patients prevents appropriate lymphoedema management. Therefore, development and dissemination of remote systems is necessary to improve care in rural areas with limited medical personnel or access to medical coordination. The authors evaluated the elements required for providing patient education on conservative therapy for lymphoedema, to determine the feasibility of remote management. The study involved connecting a health professional in a local clinic (point A) treating a patient with lymphoedema, who was present alongside the clinician, with a specialist certified lymphoedema therapist (CLT) located remotely in a university (point B). The CLT was able to greet, interview and provide guidance to the patient on conservative therapy. Direct contact with the patient was not possible, which limited visualisation, palpation, leg circumference measurement, and lymphatic drainage management. The findings suggest that remote a lymphoedema management approach involving conservative therapy benefits both patients and health professionals, particularly in rural regions. Future studies are needed to confirm the effectiveness of this approach to confirm adequate treatment.

Reliability of anthropometric measurements of a digi-board in comparison to an analog height board in Namibian children under 5 years.

Poor measurement quality has set back the utility of anthropometry in defining childhood malnutrition, prompting calls for alternative measurement techniques. This study aimed to assess the reliability of anthropometric measurements using a digital height board in comparison to an analog height board in Namibian children under 5 years of age. A cross-sectional, descriptive study was conducted (n = 425) between the age of 6 and 59 months, using anthropometric measurements of weight, height and mid-upper arm circumference. Two trained enumerators each collected four height measurements of each child: two using an analog height board and two using a digi-board. The repeated height measurements between and within the enumerators were used to determine intra- and interobserver reliability. Reliability of the digi-board was assessed using the technical error of measurement (TEM), relative TEM (%TEM), intraclass correlation and a Bland-Altman analysis to assess the agreement between the two methods. In all these assessments, the analog height board was considered as the gold standard and used for comparison. The digi-board showed superiority to the analog height board in terms of reliability (analog TEM = 0.22, digi-board TEM = 0.16). Although the digi-board has potential to improve child anthropometry, further clinical and large survey studies are needed to validate the used of this tool in routine population-based surveys.

Revisiting Waist Circumference: A Hypertension Risk Factor that Requires a More In-depth Understanding.

As a major cause of various cardiovascular diseases, the prevalence of hypertension has been increasing in the past 30 years, leading to significant socioeconomic and health burdens. Obesity is one of the major risk factors for hypertension. Body mass index (BMI) is the most used anthropometric index to measure obesity in clinical practice and to assess the risk of obesity-related diseases. However, obesity is a heterogeneous disease, and the accumulation of fat in different body regions leads to differences in cardiovascular and metabolic risks. BMI only reflects the overall obesity but does not consider the distribution of fat and muscle mass. The limitation of BMI makes it insufficient to assess the risk of hypertension attributed to obesity. In addition, waist circumference is an easily obtainable anthropometric index to evaluate abdominal fat distribution. High waist circumference is an independent risk factor for various cardiovascular diseases and all-cause mortality regardless of BMI. Preliminary data indicate that waist circumference is significantly associated with the risk of hypertension at different BMI levels. However, routine measurement of waist circumference is currently not required in current clinical guidelines or is only recommended for obese populations, indicating an insufficient understanding of waist circumference. In this review, we summarize the measurement methods and diagnostic thresholds of waist circumference for abdominal obesity, the trend of central obesity prevalence, the superiority of waist circumference over other anthropometric indices, and recent cross-sectional and longitudinal studies on the association between obesity and hypertension.

The End-to-End Fetal Head Circumference Detection and Estimation in Ultrasound Images.

In prenatal examinations, the fetal head circumference (HC) measurement is essential for assessing fetal weight and health conditions. The sonographers obtain the fetal HC manually by fitting peripheral skull ellipse in clinical practice, which is highly subjective, time-consuming, and experience-dependent. Recently, many fetal HC automatic measurement algorithms have been proposed to improve workflow efficiency in prenatal examination. But most automatic measurement algorithms focus on using fetal head segmentation as an intermediate processing step, and HC estimation relies heavily on segmentation results, which causes the accumulation of errors in the above two stages. Independent of the segmentation method, we design a regression network to generate the oriented bounding box to detect the head contour, and directly obtain the fetal head parameters with a pixel-based ellipse regression (PER) loss. Moreover, an effective 3D attention mechanism is integrated into the network to estimate HC more precisely without adding parameters in complex ultrasound images. The extensive experimental results on the public HC18 and our clinical dataset show that the proposed network provides a feasible scheme for end-to-end estimating fetal HC, and avoids the mistake brought by the intermediary processes.

Increasing region of interest width reduces neonatal circumferential strain.

There is growing interest in speckle tracking echocardiography-derived strain as a measure of left ventricular function in neonates. However, knowledge gaps remain regarding the effect of image acquisition and processing parameters on circumferential strain measurements. The aim of this study was to evaluate the effect of using different region of interest (ROI) widths on speckle tracking derived circumferential strain in healthy neonates. Thirty healthy-term-born neonates were examined with speckle-tracking echocardiography in the short-axis view. Circumferential strain values were acquired and compared using two different ROI widths. Furthermore, strain values in the different vendor-defined wall layers were also compared. Increasing ROI width led to a decrease in global circumferential strain (GCS) in the midwall and epicardial layers, the respective decreases in strain being -23.4±.6% to -22.0±1.1%, p<.0001 and 18.5±1.7% to -15.6±2.0%, p<.0001. Segmental analyses were consistent with these results, apart from two segments in the midwall. There was no statistically significant effect on strain for the endocardial layer. A gradient was seen where strain increased from the epicardial to endocardial layers. Increasing ROI width led to a decrease in GCS in the midwall and epicardium. There is an increase in circumferential strain when moving from the epicardial toward the endocardial layer. Clinicians wishing to implement circumferential strain into their practice should consider ROI width variation as a potential confounder in their measurements.

Improving Pediatric Hypertension Screening in an Academic Primary Care Setting.

Adherence to the American Academy of Pediatrics clinical practice guidelines for screening and managing high blood pressure (BP) is low. This team sought to improve recognition and documentation of relevant diagnoses in patients aged 13-20 years who presented to general pediatric clinics. The primary outcome measure was the proportion of office visits for patients ages 13-20 with a BP ≥ 120/80 with a visit or problem list diagnosis of hypertension or elevated BP. Secondary measures included (1) the proportion of patients who had their BP measured in the right arm, (2) the proportion of patients who had a mid-arm circumference measurement recorded, and (3) the proportion of patients who had a second BP reading measured at the visit. Interventions addressed key drivers for evidence-based high BP screening: standard BP measurement, electronic health record clinical decision support, and clinical pathway adoption. Data were collected over a twenty-seven-month period and plotted using the Laney p' chart. Provider documentation of elevated BP or hypertension improved from a baseline mean of 24% in April 2020 through January 2022 to 41% in February 2021 through June 2022. All secondary outcome measures also demonstrated significant improvement. This project demonstrates the feasibility of improving adherence to best practices of BP measurement in primary care clinics through education, acquisition of resources, and implementation of electronic health record flags for abnormal values.

Poster 367: Nano-Semiconductor Fibers in a Commercial Compression Sleeve Accelerates Healing of Achilles Tendon Injury in a Rat Model

Objectives: Commercial compression sleeves have been promoted to ameliorate pain secondary to arthritis and tendinopathy. The fabric of one particular sleeve is embedded with nano-semiconductor fibers that reflect thermal energy produced by the body at a photonic wavelength mimicking low-level laser therapy. The device is theorized to accelerate the inflammatory stage of tissue healing to reach the proliferation and remodeling stages at faster rates. Previous clinical studies have shown a significant improvement in patient-reported outcomes between patients who did and did not use this sleeve to treat osteoarthritis. The objective of this investigation was to determine if compression sleeves embedded with nano-semiconductor fibers can accelerate Achilles tendon healing in a rabbit model. Methods: Twelve New Zealand White rabbits—under IACUC approval—were administered intratendinous injections of 0.2% collagenase into the right Achilles tendon to simulate an acute tendon injury. Rabbits were divided into three groups: group I received the commercial compression sleeve without nano-semiconductors (n = 4), group II received the sleeve with nano-semiconductors (n = 4), and group III received an alternate sleeve design also with nano-semiconductors (n = 4). Calf circumference measurements and thermal radiation imaging of the right lower leg of each rabbit were collected days 7, 14, 21, and 28 post-injection. Two rabbits from each group were sacrificed at the 14-day and 28-day marks and the right Achilles tendons were harvested. Histological analysis using picrosirius red staining was performed to evaluate tissue organization. A custom MATLAB program (MathWorks, Natick, MA) was used to quantify the collagen fiber dispersion within the Achilles tendon samples. Results: A statistically significant difference in calf circumference was found at the 28-day mark between group I versus groups II and III: group I had an average calf circumference of 5.2 cm while groups II and III had an average calf circumference of 4.85 cm (p = 0.036) and 4.60 cm (p = 0.021) respectively. Additionally, after 28 days, group I demonstrated an average pixel density intensity on thermal radiation imaging of 1,531,192 while groups II and III yielded average pixel density intensities of 1,363,515 (p = 0.008) and 1,335,456 (p = 0.003) respectively. Histological staining showed observable alterations in collagen architecture, with group I displaying widespread disorganization and degradation of type I and type III collagen fibers near the injection site. Groups II and III displayed greater organization at the 28-day mark in comparison to group I, with signs of tissue proliferation and remodeling evident. No statistically significant differences were found between group I versus groups II and III regarding collagen fiber dispersion at both the 2-week mark (p = 0.145, p = 0.236) and the 4-week mark (p = 0.113, p = 0.268), respectively. Conclusions: The nano-semiconductor fibers embedded within a commercial sleeve significantly decreased swelling and temperature of the lower leg 28 days following acute Achilles tendon injury in a rabbit model. Furthermore, histologic analysis demonstrated greater collagen fiber and extracellular matrix organization as well as greater proliferation of type III collagen suggesting a faster transition to the proliferation stage of tissue healing.

Association between Maternal Nutritional Status Assessed by Mid-Upper Arm Circumference (MUAC) and Infant Birth Weight

Introduction: In neonatal deaths, the WHO records an average of 18 neonatal deaths, maternal deaths in developing countries are related to pregnant women suffering from malnutrition such as KEK. Therefore, malnutrition in pregnant women must be avoided, making pregnant women a target group that requires special attention. There are countries experiencing KEK incidents in pregnant women that lead to maternal and child deaths, while Indonesia is one of the parameters for determining the nutritional status of pregnant women. Nutritional status greatly influences the growth and development of the fetus. Factors related to the nutritional status of pregnant women include maternal knowledge, maternal age, and economic status; these three aspects play a crucial role in meeting nutritional needs and making decisions related to nutritional status. Objective: This study aims to determine the relationship between nutritional status in pregnant women based on LILA (Upper Arm Circumference) measurements and birth weight. Method: This research uses a cross-sectional study approach. The population in this study consists of those who have given birth from 2021 to 2023 in the working area of Puskesmas Banggae 1. Sampling was conducted using the Total Sampling technique, with a sample size of 88 respondents. The instrument used for the independent and dependent variables was a checklist, specifically the Spearman Correlation test. Result: The Spearman Correlation test yielded a significance value of 0.000, less than 0.05, indicating a relationship. Conclusion: Thus, there is a relationship between Upper Arm Circumference and Birth Weight.

Evaluation of Symmetry of Ventrodorsal Pelvic Radiographs in Dogs; A Retrospective Study

Pelvic radiographs in dogs have been used for assessments of pelvic bone, hip joint, and sacral bone in orthopaedic examinations. Thus, symmetric radiographs must be a goal to minimise medical errors. Despite the importance of symmetric radiographs, ventrodorsally pelvic radiographs are routinely evaluated using the symmetric appearance of the obturator foramen and wing of the ilium. This retrospective study was performed to evaluate the symmetry of pelvic radiographs in dogs. For this purpose, 100 pelvic radiographs were reevaluated by linear, area, and circumference measurements. The differences in percentages were remarkable for width and area values for both the ilium and obturator foramen between the left and right sides. In terms of the difference in the percentage of iliac wing width, two-thirds of radiographs showed asymmetry up to 20% and higher in the remaining one-third of radiographs. The findings of this research indicate that completely symmetrical positioning on pelvic radiographs is often not obtained.

Effects of Electro-Muscle Stimulation Exercise Combined with Mat Pilates on Pain, Anxiety, and Strength in Sedentary Females with Fibromyalgia: A Single-Blind Randomized Controlled Trial.

Fibromyalgia syndrome (FM) is a chronic pain disorder that is ranked as one of the four most common rheumatological diseases in the world. This study aims to investigate the effects of an eight-week mat Pilates and electro-muscle stimulation (EMS) with combined mat Pilates exercises on pain, depression, anxiety, and strength in sedentary women. This study is a single-blind randomized controlled trial. A total of 30 sedentary female patients (Pilates (n = 15), EMS (n = 15)) diagnosed with FM were included in the study. The patients were subjected to Beck Depression (BDIs) and Anxiety Inventories (BAIs); a Fibromyalgia Impact Questionnaire (FIQ); five different Single-Leg Hop Tests (SLHTs); modified push-up (MPU), Handgrip Strength (HGS), Deep Squat (DSQ), V-Sit Flexor, bent-arm hang (BA), sit-up and Biering-Sørensen tests; and anthropometric tests before and after the 8-week exercise program. The eight weeks of mat Pilates exercises combined with mat Pilates and EMS revealed significant results (p < 0.05) in anthropometric data (abdomen, lower abdomen, hips) (p < 0.05) except for the results of chest circumference measurements (p > 0.05). In addition, there were statistically significant positive results in BDIs, BAIs, FIQs, lower extremity (all SLHTs and DSQ), upper extremity (MPU, HGS, BA), and core (V-SIT, sit-up, Biering-Sørensen test) strength test findings (p < 0.05). Combining the mat Pilates exercises with EMS is an effective and reliable method to improve the pain, anxiety, depression, and strength of female patients diagnosed with FM.

Inter-observer reliability and anatomical landmarks for arm circumference to determine cuff size for blood pressure measurement.

Accurate arm circumference (AC) measurement is required for accurate blood pressure (BP) readings. Standards stipulate measuring arm circumference at the midpoint between the acromion process (AP) and the olecranon process. However, which part of the AP to use is not stipulated. Furthermore, BP is measured sitting but arm circumference is measured standing. We sought to understand how landmarking during AC measurement and body position affect cuff size selection. Two variations in measurement procedure were studied. First, AC was measured at the top of the acromion (TOA) and compared to the spine of the acromion (SOA). Second, standing versus seated measurements using each landmark were compared. AC was measured to the nearest 0.1cm at the mid-point of the upper arm by two independent observers, blinded from each other's measurements. In 51 participants, the mean (±SD) mid-AC measurement using the anchoring landmarks TOA and SOA in the standing position were 32.4cm (±6.18) and 32.1cm (±6.07), respectively (mean difference of 0.3cm). In the seated position, mean arm circumference was 32.2(±6.10) using TOA and 31.1(±6.03) using SOA (mean difference 1.1cm). Kappa agreement for cuff selection in the standing position between TOA and SOA was 0.94 (p<0.001). The landmark on the acromion process can change the cuff selection in a small percentage of cases. The overall impact of this landmark selection is small. However, standardizing landmark selection and body position for AC measurement could further reduce variability in cuff size selection during BP measurement and validation studies.

Obesity and risk of hypertension in preadolescent urban school children: insights from Pakistan

BackgroundChildhood obesity and hypertension are growing concerns globally, especially in developing countries. This study investigated the association between overall and central obesity at baseline, and prehypertension or hypertension at follow-up among preadolescent school children in urban Karachi, Pakistan.MethodsThis is a sub study with cohort design embedded within a feasibility trial on School Health Education Program in Pakistan (SHEPP) in preadolescents aged 6–11 years, attending two private schools conducted from 2017 to 2019. Hypertension or prehypertension at follow-up were the outcomes and obesity or central obesity at baseline were the exposure variables. Hypertension was defined as systolic blood pressure and/or diastolic blood pressure ≥ 95th percentile for age, sex, and height. Obesity was defined as body mass index for-age and sex ≥ 95th percentile, whereas central obesity was determined by waist circumference measurements ≥ 85th percentile of age, sex, and height specific cut-offs. Logistic regression analysis was used to calculate odds ratios (ORs) and 95% confidence intervals (CIs) to identify risk factors for hypertension and prehypertension.ResultsAnalysis was conducted for 908 participants, evenly distributed with 454 boys and 454 girls. Hypertension was observed in 19.8% of the preadolescents, with rates of 18.5% in boys and 21.0% in girls. Prehypertension was found in 16.8% of preadolescents, with 18% among boys and 16% among girls. Additionally, 12.8% of preadolescents were classified as obese and 29.8% had central obesity. Obesity at baseline was associated with hypertension at followup (OR 8.7, 95% CI 3.5, 20.4) in the final model after adjusting for age, gender, physical activity, sedentary behavior, fruits, vegetable intake and hypertension at baseline. Central obesity at baseline also yielded high odds, with prehypertension (OR 1.9, 95% CI 1.4, 2.8) and hypertension (OR 2.7, 95% CI 1.9, 3.9) at follow up in the final model.ConclusionThis study highlights a concerning prevalence of hypertension and prehypertension among preadolescent school-going children. Obesity and central obesity at baseline emerged as significant predictive factors for hypertension or prehypertension at followup within this cohort. The findings emphasize the urgency of implementing comprehensive school health education programs aimed at early detection and effective management of hypertension during childhood and adolescence in school settings.
