Abstract
This study aimed to determine whether amplitude modulation (A-mode) ultrasound (US) provides accurate and reliable measurements comparable to those obtained using brightness modulation (B-mode) US under diverse conditions. Thirty healthy participants (15 women and 15 men) underwent measurements of subcutaneous fat thickness (SFT), muscle thickness (MT), and muscle quality (MQ) in the trapezius and biceps brachii muscles using both US modes before and after exercises designed to stimulate the respective muscles. Among the three key indices, the results demonstrated the high validity of the A-mode, with minimal mean differences (MDs) between the two devices less than 0.91 mm and intra-class correlation coefficients (ICCs) exceeding 0.95 for all measures. In addition, the correlation coefficients between the error scores and average scores for the trapezius and biceps brachii suggested no evidence of systematic error. The trapezius MT and MQ significantly increased, and the biceps brachii MT significantly increased after the exercises (p < 0.05). Notably, both the A- and B-modes exhibited the same trend in these post-exercise changes in the muscle. This study suggests that low-cost and low-resolution A-mode US provides measurements of SFT, MT, and MQ similar to the more expensive, high-resolution B-mode imaging. A-mode US is an affordable and portable alternative for muscle assessment.

Abstract
Objective: Current evidence regarding the safety of abdominal subcutaneous injections in pregnant women is limited. In this study, we developed a predictive model for abdominal skin-subcutaneous fat thickness (S-ScFT) by gestational periods (GP) in pregnant women. Methods: A total of 354 cases were measured for S-ScFT. Three machine learning algorithms, namely deep learning, random forest, and support vector machine, were used for S-ScFT predictive modeling and factor analysis for each abdominal site. Data analysis was performed using SPSS and RapidMiner softwares. Results: The deep learning algorithm best predicted the abdominal S-ScFT. The common important variables in all three algorithms for the prediction of abdominal S-ScFT were menarcheal age, prepregnancy weight, prepregnancy body mass index (categorized), large fetus for gestational age, and alcohol consumption. Conclusion: Predicting the safety of subcutaneous injections during pregnancy could be beneficial for managing gestational diabetes mellitus in pregnant women.

Abstract
Introduction Surgical site infection (SSI) is a significant cause of postoperative morbidity resulting in an increased hospital stay and cost. Various measures have been used to predict SSI such as subcutaneous fat thickness (SCFT) and abdominal depth (AD) in case of abdominal surgeries. The objective of the study was to compare SCFT with AD to predict SSI in HPB surgeries. Methods A prospective observational study was conducted from February 2020 to February 2021, which included 76 patients who underwent elective open hepatopancreatobiliary surgeries. SCFT and AD at the level of the umbilicus were measured preoperatively using the computed tomography abdomen. The occurrence of SSI was evaluated in correlation with SCFT and AD. SCFT and AD were compared using the receiver operating characteristic curve for prediction of SSI. Results Twenty-five (32.3%) patients who underwent elective HPB surgeries developed SSI. 72% of the SSI were superficial. In multivariate analysis, only SCFT was associated with SSI, which was statistically significant. It was compared with AD using the receiver operating characteristic curve where SCFT proved to be better at predicting SSI (AUC=0.884) with cut-off =2.13 cm, sensitivity 84%, and specificity 86%), compared to AD with an AUC of 0.449. Conclusion SSI is the common cause of increased morbidity following hepato-pancreato-biliary surgeries with risk factors including SCFT and AD. Approximately one-third of patient developed SSI, with most the common being superficial SSI. SCFT at the incision site was associated with an increased rate of SSI and the better predictor for SSI as compared with the AD.

Abstract
Introduction Lateral pain around the greater trochanter (LTP) is a common complication after total hip arthroplasty (THA) that can significantly reduce quality of life. The aim of this study was to analyze the relationship between lateral trochanteric bursa repair, subcutaneous fat thickness, and trochanteric pain during the THA procedure. Materials and methods A total of 98 patients who underwent THA for hip arthrosis between 2021 and 2022 were evaluated retrospectively. For all evaluated patients, subcutaneous thickness was measured between the fascia and the skin at the incision site. Bursa repair was performed in 47 patients, while bursa excision was done in 51 patients. The data obtained included demographic information, functional scores, comorbidities, bursa repair and skin thickness values, radiographic evaluations, and other specific markers. These were compared between patients diagnosed with LTP following THA and the controls. Results No difference was observed between the study groups in terms of subcutaneous fat thickness, bursa repair, and other demographic or radiographic evaluations. As expected, there were statistically significant differences between the groups in terms of the visual analog scale (VAS) score (p=0.030) and the Harris hip score (HHS) (p=0.045). When comparing the groups with and without LTP, the VAS score was higher in the group with LTP, while the HHS was found to be lower. Conclusion Trochanteric pain is not associated with bursa repair or subcutaneous thickness. LTP cannot be predicted based on comorbidities such as smoking, BMI, or radiographic measurements.

Abstract
INTRODUCTION Although BMI is often used as a surrogate for posterior cervical subcutaneous fat thickness (SFT), the association of BMI with cervical SFT is unknown. We performed a retrospective radiographic study to analyze the relationship between BMI and cervical SFT. METHODS This was a retrospective cohort study of patients with cervical CT scans. SFT was assessed by measuring the distance (mm) from the spinous processes of C2-C7 to the skin edge. Pearson correlations and linear regression were used to analyze the relationship between BMI and SFT. One-way ANOVA was used to analyze differences in C2-C7 distances while stratifying by BMI. RESULTS A total of 96 patients were included. BMI had a moderate correlation with average C2-C7 (r=0.546, p < 0.05) SFT, and a weak to moderate correlation with each individual C2-C7 distance. The strongest correlation was at the C7 level (r= 0.583, p < 0.05). These analyses remained significant controlling for potential confounders of patient age, sex, and diabetes. No difference was found in the average C2-C7 distance in patients with BMIs of 25-30 compared to those with BMIs of 30-40 (p=0.996), whereas in patients with BMI <25 and BMI >40, differences were significant (p < 0.05). CONCLUSIONS BMI is not strongly correlated with SFT in the cervical spine. Although BMI less than 25 or greater than 40 is correlated with respectively decreased or increased cervical SFT, BMI of 25-40 is not correlated with cervical SFT. This is clinically important information for surgeons counseling patients on perioperative risk before undergoing cervical spine procedures, namely infection. Further research delineating the relationship between posterior SFT and surgical site infection in the cervical spine is warranted.

Abstract
STUDY DESIGN A retrospective matched case-control study. OBJECTIVE This study aims to investigate the value of Subcutaneous Lumbar Spine Index (SLSI) as a predictor of early surgical site infection (SSI) after lumbar intervertebral fusion surgery. METHODS A retrospective case-control study was performed on patients who underwent transforaminal lumbar interbody fusion (TLIF) from January 1, 2014 to December 31, 2019 in a single institution. Cases were defined as those who developed early SSI according to the US Center for Disease Control and Prevention criteria, and controls were matched from those patients without early SSI using the following matched criteria: gender, age, time of surgery and diabetes. Subcutaneous fat thickness (SFT) and SLSI were measured on preoperative MRI mid-sagittal T2 weighted images. RESULTS A total of 3615 patients who underwent TLIF were enrolled in this study. Thirty-three patients were included in early SSI, and sixty-six patients were selected as matched controls. Univariate analysis indicated that fusion levels (P = .007), operation time (P = .022), obesity (P = .013), SFT (P = .002) and SLSI (P = .001) were significantly associated with early SSI. Multiple logistic regression analysis revealed that multilevel fusion levels (P = .021), obesity (P = .035), a large SFT (P = .026) and a high SLSI (P = .012) were independent risk factors. Body mass index (BMI) and SLSI were moderately correlated (r2 = .55). ROC curve demonstrated that SLSI was more sensitive than SFT to predict the early SSI. CONCLUSION SLSI is a novel radiological risk factor for early SSI development and is a better indicator than SFT to predict early SSI risk after lumbar intervertebral fusion.

Abstract
BACKGROUND Laparoscopic colorectal surgery (LCRS) requires a small laparotomy at the umbilicus. The wound is small and inconspicuous, but if the patient develops an umbilical incisional hernia (UIH), the wound is visible and the patient suffers from symptoms of discomfort. However, the incidence of UIH after LCRS and its risk factors are not well understood. The purpose of this study was to investigate the risk factors for UIH after LCRS for colorectal cancer. METHODS This was a single-centre retrospective study of 135 patients with colorectal cancer, conducted at our hospital from April 2013 to March 2019. The diagnosis of UIH was based on computed tomography and physical examination findings. Preoperative patient data such as enlargement of the umbilical orifice (EUO), subcutaneous fat thickness (SFT) and intraperitoneal thickness (IPT) were collected and analysed using univariate and multivariate analyses for the presence of risk factors for UIH. RESULTS A total of 135 patients who underwent LCRS were analysed. The incidence of UIH was 20.7%. Univariate analysis revealed significantly high body mass index (BMI) ≥ 25 (P = 0.032), EUO (P < 0.001), SFT ≥18 mm (P = 0.011), and IPT ≥61 mm (P < 0.01) in the UIH group. Multivariate analysis revealed significant differences in EUO (P < 0.001), SFT ≥18 mm (P = 0.046) and IPT ≥61 mm (P = 0.022). CONCLUSION EUO was the most important risk factor for UIH, followed by IPT and SFT. These findings are predictive indicators of the development of UIH after LCRS and can be assessed objectively and easily with preoperative computed tomography.

Abstract
Background/aim The aim of this study was to evaluate the effects of a 6-month treatment regimen with exenatide on the lipid profile, high-sensitivity C-reactive protein (hsCRP), carotid intima media thickness (CIMT), visceral adiposity, and nonalcoholic fatty liver disease (NAFLD), all of which are important cardiovascular risk factors. Materials and methods This study included 45 obese patients with type 2 diabetes mellitus (T2DM). Baseline clinical findings, laboratory parameters, and ultrasonography findings were recorded. An exenatide recipe was given twice daily to the patients and, after 6 months of therapy, the same variables were compared. The compared parameters were lipid profiles, hsCRP, aspartat aminotransferase, alanine aminotransferase, gamma-glutamyl transferase, liver craniocaudal diameter, visceral fat volume, subcutaneous fat thickness, and CIMT. Liver diameter, visceral fat volume, subcutaneous fat thickness, and CIMT were measured by ultrasonography. Results After therapy, statistically significant improvements were achieved in lipid profile, hsCRP, liver enzymes, body mass index, and waist and hip circumferences. Also, statistically significant decreases were obtained in liver craniocaudal diameter, subcutaneous fat thickness, visceral fat volume, and CIMT. The reduction of CIMT and liver diameter were not correlated with BMI and HbA1c reduction. Conclusion This study showed improvement in lipid profile and hsCRP levels with exenatide treatment. We also showed decrease in both visceral fat volume and subcutaneous fat thickness. We demonstrated significant decrease in liver enzymes with significant decrease in liver diameter. These findings support the use of exenatide in patients with NAFLD and T2DM. Additionally, this study showed that exenatide treatment given twice daily reduces CIMT in obese T2DM patients.

Abstract
Background Findings from studies on obesity and benign prostatic enlargement (BPE) have been inconsistent. With a previous study done in our facility showing no correlation between anthropometric indices of obesity and BPE, this study aimed at reevaluating the association between obesity and BPE using sonographic indices of abdominal/central obesity. Materials and Methods Ninety consenting subjects with clinically confirmed BPE had their height and weight [(to calculate body mass index (BMI)] as well as waist and hip circumference [to calculate waist-hip ratio (WHR)] done. The subcutaneous, preperitoneal, and visceral fat thicknesses (SFT, PFT, and VFT, respectively) of these subjects and their prostate volumes were measured on transabdominal Ultrasonography (USS). Transrectal USS was also done to measure the total prostate and transitional zone volumes. Data were analyzed using SPSS version 22. Results WHR and waist circumference correlated positively with SFT (r = 0.325, P = 0.002 and r = 0.370, P = 0.000, respectively) and PFT (r = 0.209, P = 0.048 and r = 0.313, P = 0.003, respectively). While BMI correlated positively (r = 0.23, P = 0.029) with transrectal transitional zone volume, all three sonographic indices of adiposity correlated negatively (SFT: r = -0.223, P = 0.035; PFT: r = -0.321, P = 0.002; VFT: r = -0.242, P = 0.021) with transrectal total prostate volume. In addition, PFT correlated negatively with transabdominal prostate volume (r = -0.222, P = 0.037) and transrectal transitional zone volume (r = -0.211, P = 0.046). Conclusion The relationship of BMI with transrectal transitional zone volume was a direct one, while that of SFT, PFT, and VFT with transrectal total prostate volume as well as PFT with transabdominal prostate volume and transrectal transitional zone volume was an inverse one.

Abstract
Background: Surgical site infection (SSI) hampers the advantages of surgical management, which requires early forecast particularly in patients receiving colorectal surgery. This study is to explore potential relationship between individual abdominal anatomic characteristics including subcutaneous fat thickness (SFT), rectus abdominis thickness (RAT), and abdomen depth (AD), with the incidence of SSI in elective radical resection of colon malignancy. Materials and Methods: This retrospective case-control study has recruited 55 patients in each SSI and non-SSI group with propensity score match method. Demographics, clinical attributes, and pre- and intra-operative information were compared between groups with univariate analysis to elicit significant parameters, which were subsequently brought into logistic regression and receiver-operating characteristic (ROC) analysis. Results: Patients with SSI showed lower preoperative albumin (p = 0.0022), higher RAT (p = 0.014), AD (p = 0.029), and the multiplied value (RAT × AD) (p = 0.0026) contrasted with patients without SSI. Logistic regression demonstrated RAT × AD as an independent risk factor for SSI (OR = 1.007, p < 0.001) and a biomarker for SSI prediction (AUC = 0.83, 95% CI: 0.74 ~ 0.91). Conclusions: Preoperative RAT and abdomen depth are associated with the risk of postoperative SSI in patients receiving elective radical resection of colon cancer.

Abstract
Background Subcutaneous fat is a highly active metabolic tissue that exerts control on numerous biochemical and physiological processes in health and disease. Children are particularly susceptible to nutritional problems, hence the need to measure subcutaneous fat thickness (SFT) which can be used to determine their body composition. Ultrasonography provides an affordable, noninvasive, available technique of achieving this. Objective The aim of this study was to determine the normal values of SFT at the triceps, subscapular, and abdomen in children age 1-5 years using ultrasound in southern Nigeria. Materials and Methods This was a prospective study of 1750 healthy children age 1-5 years in nursery and primary schools in Calabar, Nigeria. Their body mass indexes were calculated from their weights and heights, while their triceps fat thickness (TFT), subscapular fat thickness (SuFT), and abdominal fat thickness (AFT) were measured using a 7.5-MHz linear array transducer of a Hitachi portable ultrasound machine. Results The mean TFT value for girls was 4.6 ± 2.0 mm and 3.99 ± 1.8 mm for boys. Girls had mean SuFT value of 2.37 ± 1.41 mm and boys 2.14 ± 1.02 mm. The mean AFT value for girls was 5.53 ± 2.94 mm and for boys 4.53 ± 2.37 mm. The values at all sites were generally higher in females than in males. Conclusion This work has provided a sonographic normogram of SFT at various sites for preschool children in Nigeria.

Abstract
INTRODUCTION Early pregnancy body mass index (BMI) is known to predict adverse pregnancy outcomes but does not account for body fat distribution. This study aimed to determine prospectively whether maternal abdominal subcutaneous fat thickness (SCFT) measured by ultrasound at the fetal morphology scan is a better predictor than BMI of mode of delivery and other pregnancy outcomes. MATERIAL AND METHODS This was a prospective cohort study of women delivering singleton neonates at a tertiary public hospital. Women were included if they had appropriate images at the routine fetal anomaly ultrasound scan and delivered in the facility. The primary outcome was mode of delivery categorized as cesarean section or vaginal delivery. The relation between maternal SCFT and BMI was described using the Pearson correlation coefficient. The association of maternal abdominal SCFT BMI at booking-in was compared with pregnancy outcomes using univariate linear and logistic regression. RESULTS SCFT and BMI were obtained for 997 women. The median (interquartile range) SCFT was 15.3 mm (12.8-19.6) and median (interquartile range) BMI 24.3 kg/m2 (21.7-28.3). Maternal abdominal SCFT and BMI were highly correlated (R2 = 0.55). Both were significantly associated with cesarean delivery: SCFT per 5 mm (odds ratio [OR] 1.32, 95% confidence interval (CI) 1.18-1.48; BMI per 5 kg/m2 OR 1.29, 95% CI 1.15-1.44. CONCLUSIONS Maternal abdominal SCFT and BMI were both significantly associated with cesarean delivery and other outcomes. More research is needed to define the strengths of maternal SCFT in predicting pregnancy outcomes.
