Abstract
Background Low birth weight (LBW) is an important predictor of neonatal morbidity and mortality. It reflects the nutritional status of the mother and the quality of health care services during pregnancy. Objective The objective of this study is to determine the factors associated with low birth weight of children born to Moroccan pregnant women in the province of El Jadida. Material and Methods This cross-sectional case-control study was carried out in the maternity ward of El Jadida provincial hospital on 344 parturient women, half of whom had given birth to children with an LBW and the other half of children with normal weight (NW) at birth. Information on maternal gestational and socioeconomic characteristics as well as eating habits was collected using a questionnaire and anthropometric measurements were taken on the newborns. Results The study identified 172 parturient who gave birth to newborns with LBW and 172 parturient who gave birth to newborns of NW. The proportions of LBW are greater in first-time mothers (50.6%) and professionally inactive (86.6%). The mean weight of LBW newborns is 2013.95 ± 372.95g compared to 3380 ± 217.59g for NW newborns. The determined factors associated with LBW are the low socio-economic level (OR = 3.18; 95% CI: 1.09-9.23), insufficient monitoring of prenatal consultation (OR = 2.91; 95% CI: 1, 71-4.95), origin from rural areas (OR = 0.52; 95% CI: 0.30-0.91) and lack of nutritional education (OR = 0.17; 95% CI: 0, 09-0.34). The daily calcium intake in mothers of newborns with LBW is 33.82% of the recommended daily allowance (RDA), the daily iron requirement coverage was 50%, folates 66, 16% and zinc 87.72% of the RDA. Conclusions Well-targeted and coordinated education and awareness-raising actions on early pregnancy and feeding pregnant women could have a positive impact on improving the birth rate of children with a weight deficit.

Abstract
Objective This study assessed the nutritional status of end-stage renal disease (ESRD) patients on maintenance hemodialysis (MHD) by utilizing bedside anthropometric measurements. Methods This prospective cross-sectional study was done from November 2020 till April 2021 on ESRD patients three times a week MHD at our centre. Anthropometric measurements including body mass index (BMI), triceps skinfold thickness (TSFT), mid-arm circumference (MAC), calf circumference (CC) and handgrip strength (HGS) were measured mid-arm muscle circumference (MAMC) was calculated, and nutritional status was determined. Results Out of 195 patients recruited in our study, 127 (65.1%) were male. The mean age was 51.2 ± 14.8 years with a minimum of 20 and a maximum of 90 years, while the mean duration of HD was 4.6 ± 4.1 years. The majority of our patients had TSFT of 60 % to 90% 93 (47.7%), indicating mild to moderate depletion of fat stores and MAMC of >90 % 128 (65.6%), indicating good protein stores. Among all anthropometric measures, BMI was strongly associated with age (<0.001), while gender and duration of MHD were associated with TSFT (p <0.001). Conclusion Anthropometric measurements are easy and inexpensive bedside methods for assessing the nutritional status of ESRD patients on MHD. Our study concluded that our MHD patients have overall good nutritional status, though our young patients have low BMI and old have obesity. Male patients have weaker HGS. With the increased number of years on MHD, malnutrition increases. Our study will help to treat physicians and nutritionists for proper nutritional planning and implementation to prevent malnutrition.

Abstract
In this study, we investigated the correlation between airway assessment tests, anthropometric measurements, and the Modified Cormack- Lehane Classification (MCLC) assessed by videolaryngoscopy in patients undergoing bariatric surgery.This study included 121 morbidly obese patients undergoing bariatric surgery. The body mass index, Modified Mallampati Score (MMS), thyromental distance, sternomental distance, interincisor distance, and neck, waist, and chest circumferences were recorded. The correlation between the airway assessment tests, anthropometric parameters, and the MCLC were analyzed. The time required for endotracheal intubation (EI) and the attempt required for EI were also recorded.Thirty-three patients were found to be at risk of a difficult EI. The MMS, neck circumference, waist circumference, chest circumference, the time required for EI, and the number of attempts for EI were positively correlated with MCLC (all P < .05). As the MMS increased, the risk of a difficult EI increased (P < .001). The cutoff values of neck, waist, and chest circumference for the risk of a difficult EI were 41.5, 153.5, and 147.5 cm, respectively (P < .05).This study indicates that the high MMS, as well as increased neck, waist, and chest circumference, should be considered EI difficulty in obese patients, even if a videolaryngoscopy is used.

Abstract
Background Tuberculosis (TB) is strongly influenced by nutritional status, with nutrition interventions being likely to have an impact on the prevalence of disease, response to drugs and quality of life. Aim The aim of this research study was to determine the nutritional profile of patients with TB and TB and human immunodeficiency virus (HIV) co-infection. Setting The study was conducted at Standerton TB Specialised Hospital, Mpumalanga. Methods A cross-sectional study was undertaken. A structured interview was conducted by the researcher with each patient. The Malnutrition Universal Screening Tool (MUST) was used to determine the risk of malnutrition. Weight, height, mid-upper arm circumference (MUAC) and triceps skinfold were measured using standard techniques. Biochemical parameters that were part of the routine hospital procedure were noted. Results More than two-thirds of the participants (68%) were found to be HIV positive. Food-related side effects included loss of appetite (59%) and dry mouth (48%). According to the MUST, 70% had a high risk of malnutrition. The median body mass index (BMI) was in the underweight category at 18.3 kg/m². About half of the participants had low MUAC measurements (51%) and triceps skinfold measurements below the 15th percentile (49.9%), indicating malnutrition. Most participants had low albumin and haemoglobin levels (79% and 92%, respectively). Conclusions Patients with both TB and TB and HIV co-infection had a compromised nutritional status and an increased risk for developing malnutrition. Interventions aimed at addressing malnutrition could make a meaningful contribution to improving the quality of life in these patients. Contribution This research provides evidence on the nutritional profile of patients with tuberculosis at Standerton TB Specialised Hospital, it gives opportunity to extend this research project to confirm these findings in other TB burdened areas.

Abstract
A comprehensive search for primary studies using a sufficient number and relevant databases is critical to minimise bias and increase the validity of a systematic review. We examined the frequency and choices of databases commonly used to provide an efficient search of primary studies for a systematic review of anthropometric measurements and dental caries among children in Asia. Twelve previous systematic reviews on a similar topic were retrieved from six databases. The frequency and choice of databases used by reviewers were determined from the methods sections. We also identified the lists of other databases usually searched in other reviews. Eligibility criteria for final databases selection were the database's scope, the topic of interest, design of the study, type of article, and the accessibility of the databases. Of the 77 databases identified, previous reviews on this topic used 21 databases, ranging from 2 to 12 databases in each review. Medline, Cochrane Library, Web of Science, and PubMed were employed most frequently. Twenty-six databases were eligible and selected for the present review. Twelve were regional databases to provide comprehensive coverage of primary studies. A systematic approach in selecting appropriate databases for searching primary studies is paramount to reduce errors, ensure coverage, and increase the validity of systematic reviews' conclusions.

Abstract
Objective: Given the unrelenting surge in the prevalence of obesity and the intensified efforts aimed at elucidating underlying mechanisms and proffering effective treatments, this study investigated the effects of lycopene on various anthropometrical indices of obesity. Methods: Thirty female Wistar rats were equally divided into two groups and fed either control diet or Western diet. After eight weeks, obese rats (fed Western diet) were divided into three groups (n=5); obese control received the vehicle, while the other two received lycopene (0.2 and 0.4 mg/kg body weight, respectively). Normal rats were grouped into three (n=5) and treated similarly. This treatment lasted for another two weeks, in addition to their respective diets. Afterwards, anthropometrical indices were taken. Results: The weight gain, adiposity index, abdominal and thoracic circumference, body mass index, and Lee index were significantly increased (p<0.05) in the obese rats compared to the normal control, by 108.3%, 102.1%, 81.5%, 97.6%, 47.4%, and 13.9%, respectively. The obese rats had significantly (p<0.05) higher adipose tissue lipid contents, daily feed (37.4%) and energy intake (66.0%), daily weight gain (108.3%), and feed efficiency (25.5%) compared to control. However, the treatment of obese rats with lycopene occasioned a dose-dependent reduction in the elevated anthropometrical and nutritional parameters. In addition, lycopene elicited significant reductions (p<0.05), ranging from 16-54%, in the adipose lipid contents. Conclusion: The data presented here illustrate the positive effects of lycopene on indices of obesity and other anthropometric parameters in obese female rats.

Abstract
MC4R, LEP, and LEPR genes are involved in the hypothalamic leptin-melanocortin regulation pathway, which is important for energy homeostasis. Our study aimed to evaluate the associations between the MC4R rs17782313, LEP rs7799039, and LEPR rs1137101 polymorphisms with obesity-related parameters in childhood and adulthood. The data were obtained from the Kaunas Cardiovascular Risk Cohort study, which started in 1977 with 1082 participants aged 12-13 years. In 2012-2014, the follow-up survey was carried out. Genotype analysis of all respondents (n = 509) aged 48-49 years was performed for the gene polymorphisms using Real-Time Polymerase Chain Reaction. Anthropometric measurements were performed in childhood and adulthood. In childhood, only skinfold thicknesses were associated with gene variants being the lowest in children with MC4R TT genotype and LEP AG genotype. In adulthood, odds of obesity and metabolic syndrome was higher in MC4R CT/CC genotype than TT genotype carriers (OR 1.8; 95% CI 1.2-2.8 and OR 1.6; 95% CI 1.1-2.4, respectively). In men, physical activity attenuated the effect of the MC4R rs17782313 on obesity. The LEP GG genotype was associated with higher BMI, waist circumference, and visceral fat level only in men. No associations of the LEPR rs1137101 polymorphisms with anthropometric measurements and leptin level were found. In conclusion, the associations of the MC4R and LEP gene polymorphisms with obesity-related parameters strengthened with age.

Abstract
BACKGROUND Cirrhosis is an irreversible disease that replaces healthy tissues with scar tissues. According to the Pakistan Medical Research Council's national general population survey (2008-2014), the ratio of cirrhosis was 4.8% among the population. OBJECTIVES To assess the nutritional status of cirrhotic patients on enteral and parenteral nutrition and to assess the degree of malnutrition among cirrhotic patients. METHODS A cross-sectional study was conducted at Shalamar and Shiekh Zayed Hospitals of Lahore from January-April 2017. The convenient sampling technique was used. Inclusion criteria were the patients with decompensated liver cirrhosis, whereas compensated patients were excluded from the study. Data were collected through the patient's file, nurse's, and dietitian's notes. The nutritional status of participants was assessed based on socio-demographic characteristics, anthropometric measurements, biochemical assessment, clinical signs, and dietary recall. Variables were categorized and compared to observe the level of significance in enteral and parenteral nutrition. SPSS version 22 was used to analyze data. RESULTS Patients on parenteral nutrition had a higher ratio of malnutrition with a significant Child-Pugh score-61.8% of patients belonged to Class C and 35.3% Class B, while in enteral support, 7.3% belonged to Class C and 43.9% patients belonged to Class B (p-value = 0.000). There was a definite relationship observed in the route of intake and malnutrition among cirrhotic patients. CONCLUSION Enteral route of nutrition is an effective and the safest way to provide appropriate nutrients according to the patient's demands.

Abstract
STUDY OBJECTIVES To evaluate predictions of moderate-to-severe-obstructive sleep apnea (MS-OSA) by the neck circumference height ratio (NHR) and waist circumference height ratio (WHR) and compare to the derived STOP-Bang Questionnaire (dSBQ) prediction. METHODS Included were 6,167 participants from the Sleep Heart Health Study (SHHS) baseline evaluation who completed polysomnograms, had anthropometric measurements, and data to compute proxy dSBQ item answers. The sample was divided randomly into derivation (n = 2,035) and validation (n = 4,132) subsets. The derivation sample was used to estimate the NHR and WHR cut points to detect MS-OSA; the validation sample was used to evaluate sensitivity (SN) and specificity (SP). RESULTS Mean age was 63.1 years, and 47.2% were male for the overall sample. In the derivation sample, a cut point ≥ 0.21 for NHR yielded a SN of 92.0% and SP of 25.0%; a cut point ≥ 0.52 for WHR yielded a SN of 91.2% and SP of 25.0% for MS-OSA. Using the validation sample, the NHR, WHR, and dSBQ areas under the receiver operator curves (AUCs) were 69.8%, 65.2%, and 70.5% respectively for MS-OSA. There was no statistical difference with listwise comparison of the NHR and dSBQ AUCs (p = 0.997); however, there was a significant difference between the WHR and dSBQ AUCs (p = 0.015) for MS-OSA. CONCLUSIONS The NHR is a viable OSA screening tool comparable to the dSBQ, independent of witnessed apneas and BMI, that can be used for different body types.

Abstract
Purpose The aim of this study was to evaluate the efficiency of multiple abdominal fat indices measured by ultrasound and anthropometric indices to predict the presence and severity of coronary artery disease (CAD) assessed by coronary angiography. Patients and Methods All participants subjected to clinical and laboratory assessments. Anthropometric measurements were taken followed by an ultrasound examination to measure fat thickness at multiple abdominal areas. Lastly, selective coronary angiography performed by the Judkins technique. Statistical analysis was performed to detect the association between all variables and CAD, followed by regression analysis, and Odds ratio (OR) was used to quantifies the strength of the association between two events. Results From the abdominal indices, the posterior right perinephric fat thickness (PRPFT) above the best cutoff value had the highest hazard ratio (HR: 12.3, p = 0.001), followed by visceral adipose tissue volume (VAT) (HR: 10.7, p < 0.001), waist circumference (WC) (HR: 6.7, p = 0.001), visceral fat thickness (VFT) (HR: 5.7, p = 0.002), and body mass index (BMI) (HR: 5.48, p = 0.017). It also showed an independent association between the severity of CAD and WC (HR: 4.28, p = 0.012), VFT (HR: 3.7, p = 0.032), VAT (HR: 3.7, p = 0.034), and waist to height ratio (WHtR) (HR: 3.3, p = 0.033). Conclusion Posterior perinephric fat thickness and visceral adipose tissue volume measured by ultrasound are strong noninvasive predictors for coronary artery disease, followed by body mass index, waist circumference and visceral fat thickness.

Abstract
Objective: Facial cleft involves complex malformations. No study assessed the facial deformity of Tessier No. 0 cleft with a bifid nose. Thus, we used anthropometric measurements to access the nose in patients. Methods: A total of 24 bifid nose deformities underwent surgery at our institution between 2010 and 2019. Standardized photographs were taken preoperatively and postoperatively. Landmarks were identified on these images; measurements for nasal analysis were performed and compared with the established Chinese norms. Surgical method differences were also analyzed. Results: The median follow-up time was 2.51 years. Postoperatively, there is a significant difference in comparison with preoperative in the nasal index, medial canthus and nose width index, nasolabial angle, nasofacial angle, ala length and nasal bridge length index, nasal tip protrusion and nasal width index, and nasal width and ala length index. Furthermore, the medial canthus and nose width index, and nasal width and ala length index were significantly larger in ordinary people, while ala length and nasal bridge length index and nasal tip protrusion and nasal width index were smaller. After surgery, most angles and index were standard except the nasolabial angle in the females, and ala length and nasal bridge length index in the males. Moreover, as for the group of costal cartilage transplantation, most index and angles have improved after surgery including nasolabial angle, nasofacial angle, ala length and nasal bridge length index, nasal tip protrusion and nasal width index, and nasal width and ala length index. However, only nasal tip protrusion and nasal width index, columella length and nasal tip protrusion index, and nasal width and ala length index in the silicone prosthesis group implantation has significance. Costal cartilage transplantation can also better improve ala length and nasal bridge length index than the silicone prosthesis implantation. Conclusion: Most defects can be repaired with surgery, but the outcome has a lack of evaluation. Thus, anthropometric assessment can serve as a material for nasal and reconstructive surgery.

Abstract
Background. Patterns of fetal growth are largely influenced by
environmental, nutritional, and socioeconomic factors more than differences in
populations. The aim of this study was to assess anthropometric measurements of
Ethiopian preterm infants at birth and compare the results with the
international INTERGROWTH-21st data. Patients and methods. We
analyzed anthropometric data on live-born singleton preterm infants enrolled in
a hospital-based multicenter study of illness in preterm infants (SIP). Eligible
newborns with gestational age of 28-36 weeks were included. Gestational age (GA)
and sex-specific mean and standard deviations (SD), 10th, 50th, 90th, centile
values for birth weight, length and head circumference (HC) were calculated and
compared with INTERGROWTH-21st data. Result. A total of 2763
preterm infants were included in the study, 54% were male. The prevalence of
small for GA (SGA) (<10th percentile) and large for GA (LGA) (>90th
percentile) were 10.8% and 9.9%, respectively. In all 3 parameters, the mean
values of boys were higher than of girls. Birth weight centiles were comparable
to international averages at lower GA, then after GA of 32 weeks the 10th, 50th,
and 90th centile values were 100-500 g less than the international averages. The
head circumference centiles were mostly comparable, and the 90th centile values
were greater than the international averages across the GA and in both sexes.
Conclusion. The infants’ birth weights were smaller at
higher GA, which may indicate maternal undernutrition in the third trimester of
pregnancy. Strengthening antenatal nutrition counseling and providing nutrition
supplementation might improve the birth weight.

Abstract
Transient or acoustic radiation force elastography (ARFE) is becoming the most extended technology to assess cervical effacement, additionally to the Bishop test and conventional ultrasound. However, a debate on the fetal safety has been opened due to the high intensity focused beam emitted to produce shear waves. This work is aimed at providing preliminary data to assess clinical effects of fetal exposure. A follow-up study in newborns of 42 women exposed to ARFE during pregnancy was carried out to explore neonatal hypoacusia, Apgar test, and anthropometry. No hypoacusia cases attributable to ARFE were observed. The Apgar test at five minutes scored normally in all the newborns. Comparisons between anthropometric measurements showed no significant statistically differences. The results preclude to state the harmfulness nor the safety of ARFE. However, given the concern on the high level of energy and the potential risk of harmful bioeffects, larger studies are recommended.

Matsumoto D, Inui F, Honda C, Tomizawa R, Watanabe M, Silventoinen K, Sakai N. Heritability and Environmental Correlation of Phase Angle with Anthropometric Measurements: A Twin Study. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2020; 17:ijerph17217810. [PMID: 33114521 PMCID: PMC7662672 DOI: 10.3390/ijerph17217810] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 10/09/2020] [Revised: 10/21/2020] [Accepted: 10/22/2020] [Indexed: 11/04/2022]
Abstract
Bioelectrical impedance analysis (BIA)-derived phase angle (PhA) is a valuable parameter to assess physical health. However, the genetic and environmental aspects of PhA are not yet well understood. The present study aimed to estimate the heritability of PhA and investigate the relationships between PhA and anthropometric measurements. PhA and skeletal muscle mass index (SMI) were examined using multi-frequency BIA in 168 Japanese twin volunteers (54 males and 114 females; mean age = 61.0 ± 16.5 years). We estimated the narrow-sense heritability of these parameters and the genetic and environmental relationships between them using a genetic twin modeling. For the PhA, 51% (95% confidence interval: 0.33, 0.64) of the variance was explained by additive genetic effects, and 49% (95% confidence interval: 0.36, 0.67) was explained by unique environmental effects. The heritability of PhA was lower than the height, body weight, and body mass index. PhA shared almost no genetic variation with anthropometric measurements and SMI but shared an environmental variation (14%) with SMI. These findings suggest that the genes affecting PhA are different than those affecting anthropometric measurements and SMI. The correlation between PhA and SMI is caused by common environmental factors.

Abstract
AIM This study aimed to develop appendicular skeletal muscle mass (ASM) estimating formulas that also consider the presence of paralysis for older adults and people with disabilities. METHODS This retrospective study analyzed 315 consecutive patients, post-stroke, aged ≥65 years, in a rehabilitation hospital. Six different ASM estimating formulas were developed using a five-fold cross-validation method and compared with the measured ASM obtained from bioelectrical impedance analysis. These formulas included age, gender, height, weight, arm circumference, triceps skinfold, calf circumference and presence of paralysis. Using Pearson's correlation coefficients (r) and intraclass correlation coefficient (ICC), we examined the correlation between the formulas and the measured ASM. The accuracy of the ASM estimating formula for detecting decreased muscle mass was evaluated using the F-value and Matthew's correlation coefficient. RESULTS Patients' mean ± SD age was 79.0 ± 8.1 years, and 51.4% of them were men. The mean ± SD bioelectrical impedance analysis-measured ASM was 13.7 ± 4.3 kg. Furthermore, 241 (76.5%) patients had decreased measured ASM. The mean adjusted R2 of the developed six formulas was 0.861-0.871. In all formulas, the r and ICC of the estimated ASM for the measured ASM were strong (r = 0.936-0.930 and ICC = 0.928-0.934). These formulas revealed excellent sensitivity (86.0-88.2%), specificity (72.5-81.1%), accuracy (0.838-0.870), F-value (0.899-0.918) and Matthew's correlation coefficient (0.509-0.612) for measured ASM depletion. CONCLUSIONS We successfully developed ASM estimating formulas using anthropometric measurements considering the presence of paralysis. Thus, these formulas are beneficial for diagnosing sarcopenia in older adults, without requiring any special equipment. Geriatr Gerontol Int 2020; 20: 1145-1150.

Abstract
INTRODUCTION Human immunodeficiency virus-related lipodystrophy is characterized by a variety of phenotypes and metabolic changes; however, consensus has not yet been reached on its diagnostic criteria. Different cutoff values for fat mass ratio have been proposed for this specific population as an objective diagnostic criterion for lipodystrophy. This study aimed to establish sex-specific reference values for fat mass ratio and to correlate them with anthropometric measurements for the diagnosis of human immunodeficiency virus-related lipodystrophy. METHODOLOGY A cross-sectional study was performed on 189 human immunodeficiency virus-infected patients under antiretroviral therapy. Anthropometric measurements were evaluated, and body composition was determined using dual-energy X-ray absorptiometry. Fat mass ratio was calculated as the ratio of the percentage of the trunk fat mass and the percentage of the lower limb fat mass. RESULTS One hundred and thirty-two patients (69%) presented lipodystrophy by objective criteria. In men, the cutoff for the fat mass ratio was 1.55 (area under the receiver operating characteristic curve: 0.73 [95% confidence interval: 0.62-0.83], p = 0.000008), with a sensitivity of 62.5%, a specificity of 70.5%, a positive predictive value of 77.8%, and a negative predictive value of 53.4%. In women, the cutoff for the fat mass ratio was 0.959 (area under the receiver operating characteristic curve: 0.70 [95% confidence interval: 0.56-0.85], p = 0.03), with a sensitivity of 83.60%, a specificity of 61.5%, a positive predictive value of 90.2%, and a negative predictive value of 47.1%. Fat mass ratio was positively correlated with waist circumference (men: r = 0.246, p = 0.019; women: r = 0.302, p = 0.014) and neck circumference (men: r = 0.304, p = 0.004; women: r = 0.366, p = 0.003) in both sexes; and body mass index (r = 0.288, p = 0.006) and waist-hip ratio (r = 0.288, p = 0.006) in men. CONCLUSION The fat mass ratio evaluated using dual-energy X-ray absorptiometry with the sex-specific cutoffs is an objective tool to define human immunodeficiency virus-related lipodystrophy.

Abstract
BACKGROUND Previous research has shown that the collection and analysis of crane operators' anthropometric characteristics is very important for operators' comfort, health and working ability and also from the aspect of performance, productivity and safety. OBJECTIVE The first aim of this survey is to collect up-to-date anthropometric data of crane operators in Serbia and to collect those data for the first time in Libya. The second aim of this survey is to compare the collected data. The third aim is to model the interior space necessary to accommodate operators in the cabins they operate in Serbia and Libya. METHODS Standing height, sitting height, lower leg length, upper leg length, shoulder width, hip breadth, arm length, foot length and weight data were collected of 83 Serbian and 50 Libyan crane operators. Descriptive statistics, correlation analysis and tests for differences between variables were conducted to examine differences between Serbian and Libyan crane operators and enable further modeling. The modeling of the cabin interior was done using both univariate and multivariate operators' models from both samples. RESULTS There are only four common correlations between variables for both samples. The only measurement without statistical differences is shoulder width. Serbian crane operators have statistically higher values of almost all measurements in comparison to Libyans. The minimal cabin interior space dimensions are 1207×1080×1884 mm for Serbian operators and 1106×1040×1790 mm for Libyan operators when using univariate approach, while multivariate approach provides more precise and comfortable accommodation within 1327×1123×1926 mm for Serbian operators and 1203×1090×1830 mm for Libyan operators. Accordingly, our survey shows that percentile models include less than the intended population proportion in the design problem with few dimensions and depends on correlations among them. CONCLUSIONS A number of problems are solved through modeling the crane operator workspace and it has been shown that cabins with different dimensions have to be offered to Serbian and Libyan markets.

Abstract
OBJECTIVE To assess the role of neck circumference (NC) in assessing insulin resistance (IR) in polycystic ovary syndrome (PCOS). DESIGN A cross-sectional study. SETTING University-affiliated hospital. PATIENT(S) One hundred forty-three women with PCOS were recruited from November 2018 to February 2020. INTERVENTION(S) None. MAIN OUTCOME MEASURE(S) The associations of NC with IR and the cutoff points of NC for IR. RESULT(S) The prevalence rates of IR were 64.3%. The patients with PCOS with IR had significantly greater values of systolic blood pressure, NC, body mass index, waist-to-hip ratio, waist circumference, fasting blood glucose, fasting insulin, and homeostasis model assessment of insulin resistance (HOMA-IR). Pearson correlation analysis showed body mass index (log-transformed), waist circumference, waist-to-hip ratio, and HOMA-IR (log-transformed) were positively correlated with NC. Multivariable linear regression showed that NC was significantly associated with HOMA-IR (log-transformed), with the standardized regression coefficient of 0.330 with adjustment for potential confounding factors. Furthermore, multivariate logistic regression analyses showed NC was associated significantly with increased risk of IR, with the adjusted odds ratio of 1.423. Additionally, NC was able to identify IR in women with PCOS; the optimal cut-off points was 34.3 cm (Youden index = 0.586). CONCLUSION(S) Neck circumference is positively associated with IR in women with PCOS. We suggest NC as a novel, simple, practical, and reliable anthropometric measure to be used to predict the risk of IR in patients with PCOS.

Abstract
Objective To explore the anthropometric changes of the auricle after auricular cartilage unfolding in moderate concha-type microtia patients, so as to provide the basis to help evaluate surgical timing and prognostic. Methods A total of 33 children with moderate concha-type microtia, who were treated with auricular cartilage unfolding between October 2016 and September 2018 and met the inclusive criteria, were included in the study. There were 24 boys and 9 girls with an average age of 1.4 years (range, 1-3 years). Sixteen cases were left ears and 17 cases were right ears. The follow-up time was 12-23 months (mean, 17.5 months). The affected auricular detailed structures were observed and quantitatively analyzed before operation and at immediate after operation. The width, length, and perimeter of auricle before operation and at immediate after operation and at last follow-up were noted with three dimensional-scanning technology. The normal auricle was noted as control. Results There were (7.5±1.0) and (11.3±0.8) structures of the affected auricle at pre- and post-operation, respectively, showing significant difference between pre- and post-operation ( t=23.279, P=0.000). The length, width, and perimeter of the affected auricle constantly increased after operation, and there were significant differences between pre-operation and immediately after operation and between immediately after operation and last follow-up ( P<0.05). The differences of length, width, and perimeter of the affected auricle between immediately after operation and last follow-up were (3.13±1.44), (2.44±0.92), and (8.50±3.76) mm, respectively. And the differences of length, width, and perimeter of the normal auricle between pre-operation and last follow-up were (3.16±1.54), (2.35±0.86), and (9.79±4.60) mm, respectively. There was no significant difference in the differences of length, width, and perimeter between the affected auricle and the normal auricle ( P>0.05). Conclusion The auricular cartilage unfolding in treatment of the moderate concha-type microtia can receive more ear structures and increase auricle sizes, which make it possible for free composite tissue transplantation. In addition, the affected and the contralateral normal auricles have a very similar growth rate and it offers the theoretical foundation for the early treatment for moderate concha-type microtia.

Abstract
OBJECTIVE The aim of the study was to evaluate hepatic steatosis in an asymptomatic group of patients with unenhanced abdominal computed tomography (CT) and to compare the results with anthropometric measurements. METHODS The study included 617 patients aged 18-93 years, who underwent unenhanced abdominopelvic CT between January 2016 and December 2017. Three imaging criteria were used in the assessment of hepatic steatosis on CT: mean region of interest (ROI) value of measured liver lobe (40 HU ≥), mean ROI value of measured liver lobe / measured spleen mean ROI value (1 ≥), mean ROI value of measured liver lobe - mean ROI value of spleen (10 HU≥). The liver fat was quantitatively assessed both visually and using multidetector CT grading. The anthropometric measurements used were the size of the liver and spleen, abdominal anterior-posterior diameter, abdominal transverse diameter, abdominal circumference, subcutaneous adipose tissue area, and anterior, posterior, and posterolateral subcutaneous adipose tissue thickness. RESULTS The prevalence of hepatic steatosis was 29.3% according to the visual evaluation, 29.8% according to the quantitative evaluation, 67.1% according to at least one criterion and 23.3% according to at least two criteria. A positive correlation was determined between hepatic steatosis and anthropometric measurements. Differences between the genders were observed in both hepatic steatosis and anthropometric measurements. CONCLUSION By setting more objective criteria for evaluation, with the possibility of quantitative analysis in particular, non-contrast CT will have a more important role in assessing liver fat in the future.

Abstract
Background Obesity is one of the main risk factors of coronary heart disease (CHD). Although a range of anthropometric measures are available to evaluate obesity, which measure is the most precise to predict the risk of CHD is still controversial. Therefore, we assess the prevalence of obesity among patients with CHD by using various anthropometric techniques to find out the most efficient method to predict the risk of CHD. Methods In this cross-sectional study, we included 300 CHD patients and 100 age and sex-matched healthy controls, aged 45-70 years. Various anthropometric measurements (waist and hip circumference, waist-hip ratio, body mass index, and body fat percentage) were taken to assess the prevalence of obesity among the selected population. Results Average waist circumference among male and female patients was significantly higher than the controls; 94.0±13.2 vs. 86.4±4.4 (p < 0.001) and 97.8±12.1 vs. 86.9±5.3 (p < 0.001) respectively. The average waist-hip ratio among patients of both genders was significantly higher than controls 1.0±.06 vs. 0.92±.04 (p < 0.001) among males and 0.96±.07 vs. 0.88±.04 (p < 0.001) among females, respectively. The average body mass index (BMI) was not different among male patients (24.6±4.0) compared to controls (24.3±2.3); however, the frequency distribution of BMI among male patients and controls was significantly different (p < 0.05), whereas female patients had significantly higher BMI compared to controls 27.7±4.9 and 25.1±2.4, (p < 0.001). Similarly, body fat percentage and visceral fat percentage were elevated among female cases vs. female controls, but no significant difference was observed in the body fat percentage of male cases vs. controls 28.0±5.0 vs. 28.1±2.7; (p > 0.05). However, visceral fat percentage was significantly elevated among male cases vs. controls 11.6±5.7 vs. 9.6±2.6 (p < 0.05). Conclusions Central adiposity markers, waist circumference (WC), waist-hip ratio (WHR), and visceral fat percentage were uniformly present in patients of both sexes and are stronger predictors of risk of CHD relative to the BMI.

Abstract
Background Juvenile breast hypertrophy is characterised by massive enlargement of the breast in the peri-pubertal period. We aimed to analyse body size measurements (body mass index [BMI], waist-to-hip circumference ratio [WHR]), digit ratio (ratio of II and IV digits' length [2D:4D]) and oestrogen receptor (ER) alpha (ERα) and progesterone receptors (PRs) in the breast gland in women with juvenile gigantomastia. Methods The study involved 30 women (mean age 25.7 years) (mean age of onset - 14.8 years). ERα and PR expressions were detected immunohistochemically in breast gland samples. For comparison, 100 controls (50 women and 50 men) were included. Results BMI and WHR in women with gigantomastia were higher than in control women and the former had a higher WHR than expected for their BMI. 2D:4D in the examined women did not differ from that in control women. However, left 2D:4D was negatively related to the age of gigantomastia onset. There were no correlations between ER and PR expressions and the analysed body and digit ratios. Conclusions The lack of a relationship between 2D:4D and juvenile breast hypertrophy may suggest that foetal exposure to sex hormones may not be crucial in its aetiology. However, the link between high left 2D:4D and early development of gigantomastia suggests that prenatal sex hormones have a role in its development timing. High WHR, and particularly high WHR relative to BMI, may indicate that these women had at some stage of development higher circulating androgens, which may have been converted to oestrogens in breasts due to local aromatase activity. Verification of this hypothesis could allow consideration of the role of aromatase inhibitors in juvenile breast hypertrophy.

Abstract
Postural instability, in particular at gait initiation (GI), and resulting falls are a major determinant of poor quality of life in subjects with Parkinson’s disease (PD). Still, the contribution of the basal ganglia and dopamine on the feedforward postural control associated with this motor task is poorly known. In addition, the influence of anthropometric measures (AM) and initial stance condition on GI has never been consistently assessed. The biomechanical resultants of anticipatory postural adjustments contributing to GI [imbalance (IMB), unloading (UNL), and stepping phase) were studied in 26 unmedicated subjects with idiopathic PD and in 27 healthy subjects. A subset of 13 patients was analyzed under standardized medication conditions and the striatal dopaminergic innervation was studied in 22 patients using FP-CIT and SPECT. People with PD showed a significant reduction in center of pressure (CoP) displacement and velocity during the IMB phase, reduced first step length and velocity, and decreased velocity and acceleration of the center of mass (CoM) at toe off of the stance foot. All these measurements correlated with the dopaminergic innervation of the putamen and substantially improved with levodopa. These results were not influenced by anthropometric parameters or by the initial stance condition. In contrast, most of the measurements of the UNL phase were influenced by the foot placement and did not correlate with putaminal dopaminergic innervation. Our results suggest a significant role of dopamine and the putamen particularly in the elaboration of the IMB phase of anticipatory postural adjustments and in the execution of the first step. The basal ganglia circuitry may contribute to defining the optimal referent body configuration for a proper initiation of gait and possibly gait adaptation to the environment.

Abstract
A good mobile phone design may increase the productivity of users, as well as their comfort. To achieve mobile users' satisfaction, there is a need to come up with an ideal measurement that would not strain the human's body parts used to control the devices.To investigate the correlation between smartphone and hand anthropometry measurements and the development of hand discomfort and pain.89 Ahlia University students between the ages of 17- and 30-year-old participated in this study. Participants completed a demographic data sheet and had both of their hand dimensions and grip strength measured.A total number of 89 participants were recruited in this study with (57.3%) females and (42.7%) males. 38% have had hand pain recently while 61.8% did not experience any hand pain. There was weak negative correlation between the phone size (r = -0.04, P = .7), hand size (r = -0.08, P = .5), and the hand grip strength (r = -0.03, P = .7) all with the reporting of hand pain. For the phone screen size and the hand lengths (r = 0.22, P = .13) there was weak positive correlation.Mobile phone manufacturers should take into account the users' comfort when designing their phones as this could lead to hand pain and other musculoskeletal problems. Furthermore, hand pain is multifactorial so hand size; phone size and grip strength may be taken into account.
