Abstract The association between LEP G-2548A gene polymorphism with increased plasma leptin and glucose levels and blood pressure in a sample of obese Saudi patients has been evaluated. This is a cross-sectional study involved 206 Saudi adult subjects (94 males and 112 females), randomly selected from the primary health care centers, Riyadh, Saudi Arabia. The study sample was categorized into three groups: 50 normotensive ND controls (age: 47.9±5.4 yr.; BMI 22.9±2.1 Kg/m2), 80 obese normotensive ND (age: 47.7±6.0 yr.; BMI 34.1±4.2 Kg/m2) and 76 obese hypertensives with T2D patients (age: 49.4±5.9 yr.; BMI: 35.1±4.7 Kg/m2). A blood sample was collected from the participants for PCR-RFLP, chemical autoanalyzer Konelab, and Luminex instruments. Analyses of LEP G-2548A gene polymorphism were determined using polymerase chain reaction (PCR), followed by restriction fragment length polymorphism (RFLP) with 2U of HhaI restriction enzyme. Plasma leptin and insulin levels were measured using the Luminex instrument. Fasting plasma glucose, total cholesterol, HDL-cholesterol, and triglycerides were measured using a chemical autoanalyzer Konelab machine. Also, blood pressure and anthropometric data were measured. The association analysis with metabolic parameters showed that homozygous AA of the LEP gene had significantly higher plasma glucose levels and HOMA-IR compared with homozygous GG (6.8±0.55 vs. 5.8±0.30; p< 0.04; 4.1±0.84 vs. 2.6±0.67; p=0.03) respectively. Besides, heterozygous GA had significantly higher plasma leptin levels compared with homozygous GG (40.0±2.6 vs. 29.6±2.6; P= 0.04). GA, AA, GA+AA genotypes of the LEP G-2548A gene polymorphism are more prevalent among individuals with hyperglycemia (OR= 3.7, 95% CI= 1.6 to 8.4, P= 0.001; OR= 3.2, 95% CI= 1.2 to 8.6, P= 0.03; OR= 3.5, 95%CI= 1.6 to 7.7, P= 0.001) respectively. A allele of the LEP gene is more prevalent among subjects with hyperglycemia (OR= 1.9, 95%CI= 1.2 to 3.0, P=0.006). G-2548A variant of the LEP gene may not be considered as a genetic risk factor for hypertension in Saudi obese patients. However, the genotypes (GA and AA) and -2548AA allele of this gene may represent important risk factors predisposing healthy subjects to develop T2DM irrespective of the status of blood pressure.

Summary Background: Non-alcoholic fatty liver disease (NAFLD), the hepatic manifestation of insulin resistance, is the most common cause of chronic liver. The present study aimed to investigate the roles of Vaspin and omentin-1 in the NAFLD-related pathology including IR, inflammation and elevated blood pressure. Methods: This cross-sectional study was conducted among 83 NAFLD patients in Jahrom, Iran. Plasma levels of omentin-1, Vaspin, hs-CRP and IL-6 were measured. Anthropometric indices, lipid profiles, liver enzymes as well as abdominal ultrasonography were assessed. Results: Partial correlations controlling for age and sex showed significant positive correlation between Vaspin and fasting blood sugar (FBS), insulin, HOMA-IR, and hs-CRP. It has been observed that omentin negatively correlated with glucose levels. Moreover, a marginally significant association has been found between Omentin levels and systolic blood pressure (SBP). Conclusions: This study shows that Vaspin and Omentin-1 are associated with inflammation, insulin resistance and serum glucose levels in patients with NAFLD.

AbstractWe investigated whether metabolically healthy normal weight adults with central obesity display worse cardiometabolic profile compared with their centrally lean counterparts. This retrospective, cross-sectional study, comprised 1 135 subjects (64% females) aged 18-to-81 years, presenting ≤2 components of metabolic syndrome. They were classified as centrally lean (waist-to-height ratio (WHtR)<0.5 and waist circumference<80 cm in females and<94 cm in males) or presenting central obesity (WHtR ≥0.5, regardless of waist circumference). Data on blood pressure, glucose homeostasis, lipid profile, renal function, high-sensitive C-reactive protein (hsCRP), uric acid, adiponectin, leptin, and soluble receptor for advanced glycation end products were compared between the groups, separately in males and females. 5.7% of males and 6.9% of females presented WHtR ≥0.5. Compared with centrally lean subjects, those with central obesity had higher BMI-adjusted fasting plasma glucose (p<0.001), and leptin levels (p<0.05); females also presented higher blood pressure (p<0.001), while males had higher hsCRP concentrations (p=0.021). These changes associated with significantly higher BMI-adjusted odds to present fasting plasma glucose >5.6 mmol/l in both genders, higher odds to present hsCRP >3 mg/l in males, and those to present elevated blood pressure in females. Our analysis suggests that in metabolically healthy normal weight subjects WHtR ≥0.5 might indicate “early increased health risk”.

Background. Impaired fasting glucose (IFG) through the nondiabetic range (100–125 mg/dL) is not considered in the cardiovascular (CV) risk profile. Aim. To compare the clustering of CV risk factors (RFs) in nondiabetic subjects with normal fasting glucose (NFG) and IFG. Material and Methods. Cross-sectional study in 3739 nondiabetic subjects. Demographics, medical history, and CV risk factors were collected and lipid profile, fasting glucose levels (FBG), C-reactive protein (hsCRP), blood pressure (BP), anthropometric measurements, and aerobic capacity were determined. Results. 559 (15%) subjects had IFG: they had a higher mean age, BMI, waist circumference, non-HDL cholesterol, BP, and hsCRP (p<0.0001) and lower HDL (p<0.001) and aerobic capacity (p<0.001). They also had a higher prevalence of hypertension (34% versus 25%; p<0.001), dyslipidemia (79% versus 74%; p<0.001), and obesity (29% versus 16%; p<0.001) and a higher Framingham risk score (8% versus 6%; p<0.001). The probability of presenting 3 or more CV RFs adjusted by age and gender was significantly higher in the top quintile of fasting glucose (≥98 mg/dL; OR = 2.02; 1.62–2.51). Conclusions. IFG in the nondiabetic range is associated with increased cardiovascular RF clustering.

The study evaluates the prevalence, knowledge, attitude, and practices of non-communicable diseases (NCDs) among adult Orang Asli and Malay ethnicity in Negeri Sembilan, Malaysia. This cross-sectional study involving 634 respondents aged 18 years and above of Orang Asli (51.3%) and Malays (48.7%) from the rural villages. Structured interview questionnaire for disease history and KAP level conducted. Weight, height, waist circumference, blood pressure, and blood glucose levels then measured. Prevalence of NCDs was higher among Malays compared to Orang Asli with hypertension (35.0% vs 14.8%), hypercholesterolemia (31.1% vs 5.2%), and diabetes mellitus (16.2% vs 4.3%), respectively. Malays also had a higher percentage of being abdominal obese (70.6% vs 59.7%) and increased blood pressure (54.4% vs 29.8%). Multivariate analysis indicates hypercholesterolemia [OR=6.035 (95%CI: 3.150,11.561)], abdominal obesity [aOR= 1.807 (95%CI: 1.065, 3.067)], and increased in blood pressure [aOR= 2.359 (95%C1: 1.619,3.437)] have a significant relation with Malay ethnicity. For Orang Asli, 51.7% had poor knowledge, 72.3% had a good attitude, and 16.0% had a good practice. Knowledge and attitude scores were significantly less among Orang Asli with no significant difference for practice compared to the Malays. The prevalence of NCDs among the Malays is alarmingly high, with an increasing trend among Orang Asli, which needs immediate attention. The NCDs and obesity were significant among Malays but also showed a worrying trend in the Orang Asli as the good practice on a healthy life-style was low in both ethnicities. Thus, proper education and promotion regarding NCDs needed for diseases screening and prevention.

Background: The effectiveness of self-monitoring of blood glucose (SMBG) in type 2 diabetes mellitus (T2DM) patients is debated in the literature. We aimed at elucidating the association and patterns of complications between SMBG use and plasma glucose values. Methods: This cross-sectional study comprised 303 participants from outpatient departments with T2DM for over 12 months. We analyzed sociodemographic and clinical variables including: anthropometry, SMBG use, disease duration, treatment modality, complications, plasma glucose level, and glycated hemoglobin level (%). Results: The mean duration of T2DM was 93±76 months. Participants were grouped into SMBG users (n=115, 38%) and non-SMBG users (n=188, 62%). The mean fasting plasma glucose levels of SMBG and non-SMBG users were 140.7±42.7 (95% Confidence Interval [95%CI]: 132.72;148.67) mg/dl and 145.4±50 (95%CI: 138.12;152.67) mg/dl (p=0.03), respectively. The mean post-prandial plasma glucose levels of the SMBG and non-SMBG groups were 202±63.42 (95%CI: 190.23;213.76) mg/dl and 209±84.54 (95%CI: 196.56;221.43) mg/dl (p=0.002), respectively. The mean difference in HbA1c among the groups were 8.14±1.69% (95%CI: 7.59;8.68) and 8.15±1.98% (95%CI: 7.27;9.02) (p=0.4), respectively. Hypoglycemia (n=50, 43.5%) was the most common complication. The prevalence of neuropathy (n=5, 4.3%, p=0.036) and cardiovascular disease (n=21, 18.3%, p=0.042) were significantly higher in the SMBG group. Conclusion: Although plasma glucose values were significantly lower in the SMBG group, its clinical significance remains questionable. Furthermore, many participants in both the groups had shortfalls in awareness, monitoring, and glycemic control. SMBG use needs to be evaluated in a cohort of patients with T2DM with adequate health awareness.

It was previously reported that dietary intake is an important trigger for systemic inflammation and one of the lifestyle factors for the development of cardiovascular diseases. The aim of this study was to evaluate the association between Dietary Inflammatory Index (DII) score and body weight, blood pressure, lipid profile and leptin in an Indonesian population. This was a cross-sectional study conducted in 503 Indonesian adults. The DII score was calculated based on data of 30 nutrients and food components. Anthropometric profile, blood pressure, lipid profile, and leptin were measured. The association of these variables with the DII score was analyzed. The DII score was not associated with body weight, body mass index (BMI), body fat, waist circumference, hip circumference, systolic and diastolic blood pressure, triglycerides, and high-density lipoprotein (HDL) (both unadjusted and after adjustment for covariates). However, plasma leptin concentration was significantly associated with the DII score (B = 0.096, p = 0.020). Plasma leptin also increased significantly across tertiles of the DII score (ANCOVA, p = 0.031). This positive association between the DII score and plasma leptin concentration suggests a role for the inflammatory properties of the diet in regulating adipose tissue inflammation.

Cardiometabolic Profile

Abstract Background Adolescents’ health-related behavior varies from weekday to weekend. Only few studies, however, have examined to which degree such variation will affect markers of cardiometabolic health. Therefore, the primary aim of this study is to examine if markers of cardiometabolic health differ between different days of the week in adolescents. Methods This cross-sectional school-based study included up to 581 participants, 11–17 years old. Markers of metabolic health were insulin, glucose, triglyceride, HDL-cholesterol (HDL-C), LDL-cholesterol (LDL-C) and blood pressure. Linear mixed regression modelling was used to examine the cardiometabolic profile across weekdays. Results Significant declining trends were observed across the week in adolescents’ levels of cardiometabolic health markers. Lower levels of insulin (16.1%), glucose (2.6%) and triglyceride (24.7%) were observed on Fridays compared to Mondays (p ≤ 0.006). Gradual improvement in measurement profiles across weekdays was less apparent for HDL-C, LDL-C, systolic blood pressure and diastolic blood pressure (P ≥ 0.06). Analyses stratified by sex suggested a more noticeable pattern of gradual improvement across weekdays in boys than in girls. Conclusion Significantly lower levels of insulin, glucose and triglyceride were observed in adolescents on Fridays compared to Mondays. However, when sex specific analyses were performed significant profile variations were only observed across the week in boys. More research is needed to better understand which behavioral factors in particular seem to influence weekly variation in markers of cardiometabolic health - especially since such variation potentially will have an impact on how assessments of markers of cardiometabolic health optimally should be planned, standardized and carried out, both in research and in medical practice.
