The Validity of Body Adiposity Indices in Predicting Metabolic Syndrome and Its Components among Egyptian Women

AIM: To assess the associations between the body adiposity indices and risk of metabolic syndrome (MS) and its components in Egyptian women and to evaluate their predictive power.MATERIALS AND METHODS: This was a cross-sectional analysis performed on 180 Egyptian women aged between 25-35 years. They were 90 women with MS diagnosed by International Diabetes Federation (IDF) and 90 healthy age matched controls. Body adiposity index (BAI), body mass index (BMI), waist to hip ratio (WHR) and waist to height ratio (WHtR) were calculated and serum samples were analyzed for metabolic parameters. Receiver operating characteristic curves (ROC) was used to determine the discriminatory capacity of BAI, WHR WHtR and BMI for MS.RESULTS: Area under the curve (AUC) was highest for BIA, followed by WHR, WHtR and then BMI. All adiposity indices were significantly correlated with metabolic components and BAI had the highest correlation coefficients compared to other indices.CONCLUSION: BAI is a practical predictor for MS and has satisfactory diagnostic accuracy for diagnosing MS among Egyptian women and can be used in addition to WHR, WHtR and BMI for identifying MS in the field studies

Combination of Human Amniotic Fluid Derived-Mesenchymal Stem Cells and Nano-hydroxyapatite Scaffold Enhances Bone Regeneration

BACKGROUND: Human amniotic fluid-derived stem cells (hAF-MSCs) have a high proliferative capacity and osteogenic differentiation potential in vitro. The combination of hAF-MSCs with three-dimensional (3D) scaffold has a promising therapeutic potential in bone tissue engineering and regenerative medicine. Selection of an appropriate scaffold material has a crucial role in a cell supporting and osteoinductivity to induce new bone formation in vivo. AIM: This study aimed to investigate and evaluate the osteogenic potential of the 2nd-trimester hAF-MSCs in combination with the 3D scaffold, 30% Nano-hydroxyapatite chitosan, as a therapeutic application for bone healing in the induced tibia defect in the rabbit. SUBJECT AND METHODS: hAF-MSCs proliferation and culture expansion was done in vitro, and osteogenic differentiation characterisation was performed by Alizarin Red staining after 14 & 28 days. Expression of the surface markers of hAF-MSCs was assessed using Flow Cytometer with the following fluorescein-labelled antibodies: CD34-PE, CD73-APC, CD90-FITC, and HLA-DR-FITC. Ten rabbits were used as an animal model with an induced defect in the tibia to evaluate the therapeutic potential of osteogenic differentiation of hAF-MSCs seeded on 3D scaffold, 30% Nano-hydroxyapatite chitosan. The osteogenic differentiated hAF-MSCs/scaffold composite system applied and fitted in the defect region and non-seeded scaffold was used as control. The histopathological investigation was performed at 2, 3, & 4 weak post-transplantation and scanning electron microscope (SEM) was assessed at 2 & 4 weeks post-transplantation to evaluate the bone healing potential in the rabbit tibia defect. RESULTS: Culture and expansion of 2nd-trimester hAF-MSCs presented high proliferative and osteogenic potential in vitro. Histopathological examination for the transplanted hAF-MSCs seeded on the 3D scaffold, 30% Nano-hydroxyapatite chitosan, demonstrated new bone formation in the defect site at 2 & 3 weeks post-transplantation as compared to the control (non-seeded scaffold). Interestingly, the scaffold accelerated the osteogenic differentiation of AF-MSCs and showed complete bone healing of the defect site as compared to the control (non-seeded scaffold) at 4 weeks post-transplantation. Furthermore, the SEM analysis confirmed these findings. CONCLUSION: The combination of the 2nd-trimester hAF-MSCs and 3D scaffold, 30% Nano-hydroxyapatite chitosan, have a therapeutic perspective for large bone defect and could be used effectively in bone tissue engineering and regenerative medicine

Prediction of Gut Wall Integrity Loss in Viral Gastroenteritis by Non-Invasive Marker

BACKGROUND: Intestinal fatty acid binding proteins (I-FABPs) are mainly expressed in the intestinal villi, which are the initial site of destruction in viral gastroenteritis.AIM: This study was designed to assess serum I-FABPs as a predictor of gut wall integrity loss in viral gastroenteritis.PATIENTS AND METHODS: This case-control cross-sectional study was conducted on 93 cases of acute viral gastroenteritis. Twenty-eight healthy children matching in age were recruited as control group. Serum I-FABPs were measured using ELISA technique. Viral detection and typing were done by PCR for adenovirus, and by Reverse transcriptase PCR for rotavirus, astrovirus and norovirus.RESULTS: Serum I-FABPs level was significantly higher in the cases compared to the controls and was also higher in the 46 rotavirus gastroenteritis cases compared to other viral gastroenteritis cases. Serum I- FABPs level was significantly higher in severely dehydrated cases as compared to mildly dehydrated ones (P=0.037).CONCLUSION: Serum I-FABPs could be used as an early and sensitive predictor marker of gut wall integrity loss in children with viral gastroenteritis and its level can indicate case severity

The relation between glutathione S-Transferase M1 null-genotype and cardiac problems in beta-thalassemia

This work was carried out to investigate the role of Glutathione S-Transferase M1 (GSTM1) null genotype frequency in prognosis of β-thalassemia, and to detect the correlation between GSTM1 null genotype and appearance of cardiac complications in β-thalassemia. Materials and Methods. The studied groups in the present work were divided to three groups (group I: 20 healthy subjects, group II: 56 β-thalassemic patients and group III: 16 β-thalassemic patients with cardiac complications were taken from group II). The measurement of human high sensitive C-reactive protein (hs-CRP) was performed using nephelometry. GSTM1 genotype was detected by Polymerase Chain Reaction (PCR) and cardiac complications were determined by using Echocardiography. Results. A statistically significant increase in hs-CRP and interleukin-6 (IL-6) levels was found in β-thalassemic patients with cardiac complications compared to normal subjects. Results showed no relation between GSTM1 null genotype frequency neither with β-thalassemia nor with cardiac complications appearance, where the interaction between GSTM1 null genotype in β-thalassemic patients with cardiac complications and healthy subjects were insignificant compared to subjects with GSTM1 non-null genotype. Conclusions. GSTM1 null genotype frequency has no role in β-thalassemia or cardiac complications appearance

Metabolic abnormalities in young Egyptian women with polycystic ovary syndrome and their relation to ADIPOQ gene variants and body fat phenotype

Background: Polycystic ovary syndrome (PCOS) is the most common endocrine disorder. It is associated with high prevalence of metabolic risk factors, but little is known about the prevalence of metabolic syndrome (MS) and its components among Egyptian PCOS women. The objective of the study was to determine the metabolic abnormalities among young Egyptian women with PCOS and evaluate their relation with adiponectin gene (ADIPOQ) variants and body fat adiposity pattern. Materials and methods: The present study included 80 PCOS women and 80 healthy women with similar age and body mass index. All participants underwent clinical, anthropometric, biochemical, ultrasonographic and adiponectin (ADIPOQ) gene 11391G>A (rs17300539) examinations. Insulin resistance was assessed by the Homeostatic model assessment for insulin resistance (HOMA-IR). Results: MS was identified in 22.5% of PCOS women. The most prevalent MS components in PCOS women were central obesity, decreased high-density lipoprotein cholesterol (HDL-C), and increased triglycerides (TG), blood pressure (BP) and fasting glucose levels. The study found association between ADIPOQ promoter variants −11391G>A and MS in PCOS women. Moreover, multivariate logistic regression analysis showed association between abdominal fat accumulation and IR in PCOS. Conclusion: The prevalence of MS was significantly higher in PCOS women than controls, and central obesity and hypertension are risk factors for insulin resistance. Moreover, obesity plays a key role in the development of PCOS and ADIPOQ −11391G>A gene variants showed association with MS
