Western blotting is an important technique used in cell and molecular biology. By using a western blot, researchers are able to identify specific proteins from a complex mixture of proteins extracted from cells. The technique uses three elements to accomplish this task: (1) separation by size, (2) transfer to a solid support, and (3) marking target protein using a proper primary and secondary antibody to visualize. This paper will attempt to explain the technique and theory behind western blot, and offer some ways to troubleshoot.

Background: Urinary tract Infection (UTI) is among the most common infections described in outpatient setting and hospital patients. In almost all cases empirical antimicrobial treatment initiates before the laboratory results of urine culture are available; thus antibiotic resistance may increase in uropathogens due to frequent use of antibiotics. Aims: The study was designed to find the prevalence of UTI in females with urinary tract symptoms, to determine the causative organism (s) of UTI, and to determine the antibiotic susceptibility pattern of microbial agents isolated from urine culture (antibiogram). Materials and Methods: The prospective, observational study involved 139 females, aged 15 years and above clinically suspected for UTI attending outpatient Departments of Vivekananda Polyclinic and Institute of Medical Sciences, Lucknow. A structured questionnaire was used to interview the study subjects. A chi-square test and Fisher Exact test were used to analyze data. Results: The overall prevalence of UTI was found to be 45.32% (63/139). Escherichia coli (33.1%) and Klebsiella pneumoniae (7.9%) were the most common organisms isolated. The most effective antibiotic for both was Nitrofurantoin. Conclusions: Regular monitoring is required to establish reliable information about susceptibility pattern of urinary pathogens for optimal empirical therapy of patients with UTI.

Paraoxonase 1 (PON1) is a hydrolytic enzyme with wide range of substrates, and capability to protect against lipid oxidation. Despite of the large number of compounds that can be hydrolyzed by paraoxonase, the biologically relevant substrates are still not clearly determined. There is a massive in vitro and in vivo data to demonstrate the beneficial effects of PON1 in several atherosclerosis-related processes. The enzyme is primarily expressed in liver; however, it is also localized in other tissues. PON1 attracted significant interest as a protein that is responsible for the most of antioxidant properties of high-density lipoprotein (HDL). Several bioactive molecules such as dietary polyphenols, aspirin and its hydrolysis product salicylate, are known to stimulate PON1 transcription activation in mouse liver and HepG2 cell line. Studies on the activity, function, and genetic makeup have revealed a protective role of PON1. Some striking data were obtained in PON1 gene knockout and PON1 transgenic mouse models and in human studies. The goal of this review is to assess the current understanding of PON1 expression, enzymatic and antioxidant activity, and its atheroprotective effects. Results from in vivo and in vitro basic studies; and from human studies on the association of PON1 with coronary artery disease (CAD) and ischemic stroke will be discussed.

This paper review seasonal patterns across twelve cardiovascular diseases: Deep venous thrombosis, pulmonary embolism, aortic dissection and rupture, stroke, intracerebral hemorrhage, hypertension, heart failure, angina pectoris, myocardial infarction, sudden cardiac death, venricular arrythmia and atrial fibrillation, and discuss a possible cause of the occurrence of these diseases. There is a clear seasonal trend of cardiovascular diseases, with the highest incidence occurring during the colder winter months, which have been described in many countries. This phenomenon likely contributes to the numbers of deaths occurring in winter. The implications of this finding are important for testing the relative importance of the proposed mechanisms. Understanding the influence of season and other factors is essential when seeking to implement effective public health measures.

Background: Low serum vitamin D can cause myalgia, myositis, myopathy, and myonecrosis. Statin-induced myalgia is a major and common cause of statin intolerance. Low serum vitamin D and statins, additively or synergistically, cause myalgia, myositis, myopathy, and/or myonecrosis. Statin-induced myalgia in vitamin D deficient patients can often be resolved by vitamin D supplementation, normalizing serum vitamin D levels. Aims: In 74 men and 72 women (age 59 ± 14 years) intolerant to ≥2 statins because of myalgia, myositis, myopathy, or myonecrosis and found to have low (<32 ng/mL) serum vitamin D, we prospectively assessed whether vitamin D supplementation (vitamin D2: 50,000-100,000 units/week) to normalize serum vitamin D would allow successful rechallenge therapy with statins. Materials and Methods: Follow-up evaluation on vitamin D supplementation was done on 134 patients at 6 months (median 5.3), 103 patients at 12 months (median 12.2), and 82 patients at 24 months (median 24). Results: Median entry serum vitamin D (22 ng/mL, 23 ng/mL, and 23 ng/mL) rose at 6 months, 12 months, and 24 months follow-up to 53 ng/mL, 53 ng/mL, and 55 ng/mL, respectively, (P < .0001 for all) on vitamin D therapy (50,000-100,000 units/week). On vitamin D supplementation, serum vitamin D normalized at 6 months, 12 months, and 24 months follow-up in 90%, 86%, and 91% of the patients, respectively. On rechallenge with statins while on vitamin D supplementation, median low-density lipoprotein cholesterol (LDLC) fell from the study entry (167 mg/dL, 164 mg/dL, and 158 mg/dL) to 90 mg/dL, 91 mg/dL, and 84 mg/dL, respectively, (P < .0001 for all). On follow-up at median 6 months, 12 months, and 24 months on statins and vitamin D, 88%, 91%, and 95% of the previously statin-intolerant patients, respectively, were free of myalgia, myositis, myopathy, and/or myonecrosis. Conclusions: Statin intolerance because of myalgia, myositis, myopathy, or myonecrosis associated with low serum vitamin D can be safely resolved by vitamin D supplementation (50,000-100,000 units /week) in most cases (88-95%).

Background: Type 2 diabetes (T2DM) mellitus is a serious implication of obesity. The effect of insulin therapy on levels of inflammatory markers among obese and non-obese diabetics has been inadequately studied. Aim: The study aimed to analyze the preinsulin and postinsulin levels of tumor necrosis factor α (TNF-α) and IL-6 in nonobese and obese T2DM patients. Materials and Methods: We assessed TNF-α and IL-6 levels in healthy controls (n=10) and diabetic patients (obese and nonobese; n=20 each) and analyzed the postinsulin effect on TNF-α and IL-6 levels after 24 and 48 weeks. TNF-α and IL-6 levels were also correlated with fasting plasma glucose of obese and nonobese diabetic patients after insulin therapy. Results: There is augmentation of TNF-α and IL-6 levels in diabetic patients and augmentation is more in obese than in nonobese diabetics. The obese group showed a significant decrease (P value<0.05) after 24 weeks of insulin therapy and an extremely significant decrease ( P<0.001) in TNF-α and IL-6 levels after 48 weeks of therapy. The nonobese group showed an extremely significant decrease ( P<0.001) in TNF-α and IL-6levels after 24 and 48 weeks both. Conclusion: There is augmented inflammation in diabetes and it is more in obese diabetics. Insulin therapy tends to counter this inflammation, but the response is delayed in obese diabetics.

Hypercalcemia of malignancy is a common finding typically found in patients with advanced stage cancers. We aimed to provide an updated review on the etiology, pathogenesis, clinical presentation, and management of malignancy-related hypercalcemia. We searched PubMed/Medline, Scopus, Embase, and Web of Science for original articles, case reports, and case series articles focused on hypercalcemia of malignancy published from 1950 to December 2014. Hypercalcemia of malignancy usually presents with markedly elevated calcium levels and therefore, usually severely symptomatic. Several major mechanisms are responsible for the development of hypercalcemia of malignancy including parathyroid hormone-related peptide-mediated humoral hypercalcemia, osteolytic metastases-related hypercalcemia, 1,25 Vitamin D-mediated hypercalcemia, and parathyroid hormone-mediated hypercalcemia in patients with parathyroid carcinoma and extra parathyroid cancers. Diagnosis should include the history and physical examination as well as measurement of the above mediators of hypercalcemia. Management includes hydration, calcitonin, bisphosphonates, denosumab, and in certain patients, prednisone and cinacalcet. Patients with advanced underlying kidney disease and refractory severe hypercalcemia should be considered for hemodialysis. Hematology or oncology and palliative care specialists should be involved early to guide the options of cancer targeted therapies and help the patients and their closed ones with the discussion of comfort-oriented care.

Background: Definite etiology of amyotrophic lateral sclerosis (ALS) is still a matter of debate. Aims: The study was designed to evaluate the role of environmental, occupational, and familial risk factors in development of ALS. Materials and Methods: This was a case control study of 110 cases of definite ALS with 240 age and sex matched controls. Investigations were done on the following aspects- family history, occupation, living place, source of drinking water, exposure to industrial, chemical, agricultural toxins and heavy metals, physical and electrical injury, working under magnetic field for more than 10 years in both the groups. Clinical examinations, electrophysiological, and neuroimaging studies were done in every patient. Chi square test, logistic regression analysis, and calculation of odds ratio were used to analyze the data. Results: Rural livings (odds ratio = 1.99), smoking (odds ratio = 1.88), insecticides, and pesticides exposures (odds ratio = 1.61), electrical injury (odds ratio = 6.2) were detected as the associated factors in development amyotrophic lateral sclerosis. Conclusions: The study expressed the need of extensive research globally in molecular and genetic levels to detect the associated factors in etiopathogenesis of ALS for better understanding the etiology and for remedial aspects.

Background: Oxidative stress has been considered to be a pathogenic factor of diabetic complications including nephropathy. There are many controversies and limited studies regarding the antioxidant enzymes in diabetic nephropathy. Aim: This study was to evaluate the levels of antioxidant enzymes and lipid peroxidation in Type-2 Diabetes Mellitus (DM) patients with and without nephropathy. Materials and Methods: The study included 90 age and sex matched subjects. Blood samples of all subjects were analyzed for all biochemical and oxidative stress parameters. Results: The malondialdehyde (MDA) levels and catalase (CAT) activity were significantly increased and reduced glutathione (GSH) levels and activities of glutathione peroxidase (GPx) and glutathione reductase (GR) were significantly decreased in Type-2 DM with and without nephropathy as compared to controls and also in Type-2 DM with nephropathy as compared to Type-2 DM without nephropathy. There were an excellent positive correlation of glycohemoglobin (HbA1c) with MDA and a good negative correlation of GPx with GSH in controls. There were positive correlations of GR, CAT, and superoxide dismutase (SOD) with MDA in Type-2 diabetes patients with nephropathy. Conclusions: Intensity of oxidative stress in Type-2 diabetic patients with nephropathy is greater when compared with Type-2 diabetic patients without nephropathy as compared to the controls.

Context: Type IV collagen is a type of collagen found primarily in the skin within the basement membrane zone. The type IV collagen C4 domain at the C-terminus is not removed in post-translational processing, and the fibers are thus link head-to-head, rather than in a parallel fashion. Also, type IV collagen lacks a glycine in every third amino-acid residue necessary for the tight collagen helix. Thus, the overall collagen-IV conformation is structurally more pliable and kinked, relative to other collagen subtypes. These structural features allow collagen IV to form sheets, which is the primary structural form found in the cutaneous basal lamina. There are six human genes associated with collagen IV, specifically COL4A1, COL4A2, COL4A3, COL4A4, COL4A5 and COL4A6. The aim of this review is to highlight the significance of this protein in normal skin, and in selected diseases. Results: The alpha 3 protein constituent of type IV collagen is thought to be the antigen implicated in Goodpasture's syndrome, wherein the immune system attacks the basement membranes of the renal glomeruli and pulmonary alveoli. In addition, mutations to the genes coding for type IV collagen lead to the Alport syndrome. Furthermore, autoantibodies directed against denatured human type IV collagen have been described in rheumatoid arthritis, scleroderma, and SLE. Structural studies of collagen IV have been utilized to differentiate between subepidermal blistering diseases, including bullous pemphigoid, acquired epidermolysis bullosa, anti-epiligrin cicatricial pemphigoid, and bullous lupus erythematosus. Collagen IV is also of importance in wound healing and in embryogenesis. Conclusions: Pathological studies have demonstrated that minor structural differences in collagen IV can lead to distinct, clinically different diseases.

Errors in potassium measurement can cause pseudohyperkalemia, where serum potassium is falsely elevated. Usually, these are recognized either by the laboratory or the clinician. However, the same factors that cause pseudohyperkalemia can mask hypokalemia by pushing measured values into the reference interval. These cases require a high-index of suspicion by the clinician as they cannot be easily identified in the laboratory. This article discusses the causes and mechanisms of spuriously elevated potassium, and current recommendations to minimize those factors. "Reverse" pseudohyperkalemia and the role of correction factors are also discussed. Relevant articles were identified by a literature search performed on PubMed using the terms "pseudohyperkalemia," "reverse pseudohyperkalemia," "factitious hyperkalemia," "spurious hyperkalemia," and "masked hypokalemia."

Gallbladder cancer is a rather uncommon disease, when it gives symptoms it has usually reached an incurable stage. Therefore, every attempt must be made to find the asymptomatic stages and look for premalignant gallbladder polyps. Even if gallbladder cancer is a rare disease, gallbladder polyps are common, only a few polyps develop to cancer. This makes gallbladder polyps another problem: which are the polyps that must be surgically removed, which shall be followed-up, or for how long? The author used the keyword "gallbladder polyps" in PubMed and reviewed the scientific literatures published from January 2000 to December 2011. The present review article has summarized almost all respects of gallbladder polyp, including the risk factors, clinical diagnosis and management, and comments made from the author, in which clinical treatments are recommended. It is author's purpose that the 11-year-knowledge about gallbladder polyps summarized from all worlds' literatures is enough to know how clinicians will handle the next patient with gallbladder polyp.

Venous thromboembolism (VTE) is the leading cause of morbidity and mortality among hospitalized patients. We searched the PubMed database and reviewed the articles published until June 2011. Articles related to the D-dimer and VTE were considered to write this paper. Many factors play a key role in changing the sensitivity and specificity of D-dimer testing, including the extent of thrombosis and fibrinolytic activity, duration of symptoms, anticoagulant therapy, comorbidity due to surgical or medical illnesses, inflammatory diseases, cancer, elderly age, pregnancy and the postpartum period, and previous VTE. Many previous studies have shown that the D-dimer test is highly sensitive (>95%) in acute deep venous thrombosis or pulmonary embolism, usually with a cut-off value of 500 μg FEU/l, which reasonably rules out acute VTE, particularly in patients with low clinical probability (LCP) or intermediate clinical probability. Patients with high D-dimer levels upon presentation may prompt a more intense diagnostic approach, irrespective of pretest probability. Studies performed after a negative D-dimer for 3 months proved the high negative predictive value (NPV) of D-dimer testing together with LCP in patients with suspected VTE. Among oncology patients, D-dimer testing has the highest sensitivity and NPV in excluding VTE. The new cutoff values of D-dimer testing were analyzed in a recent prospective study of pregnant women; they are 286 ng DDU/ml, 457 ng DDU/ml, and 644 ng DDU/ml for the first, second, and third trimesters, respectively.

Background: The increase in invasive fungal infections (IFIs) in neonatal intensive care unit (NICU) is jeopardizing the survival of preterm neonates. Probiotics modulating the intestinal microflora of preterm neonates may minimize enteral fungal colonization. Aims: This study was to examine whether probiotic supplementation in neonates reduced fungal septicemia. Materials and Methods: This prospective, randomized, double blind trial investigating the supplementation of preterm infants with a probiotic was done from May 2012 to April 2013, with 112 subjects randomized into two groups. Primary outcome: Decreased fungal colonization in gastrointestinal tract. Others: Incidence of late onset septicemia; duration of the primary hospital admission; number of days until full enteral feeds established. Results: Full feed establishment was earlier in probiotics group compared to placebo group (P = 0.016). The duration of hospitalization was less in the probiotic group (P = 0.002). Stool fungal colonization, an important outcome parameter was 3.03 ± 2.33 × 10 ⁵ colony formation units (CFU) in the probiotics group compared to 3 ± 1.5 × 10 ⁵ CFU in the placebo group (P = 0.03). Fungal infection is less in the study group (P = 0.001). Conclusion: The key features of our study were reduced enteral fungal colonization, reduce invasive fungal sepsis, earlier establishment of full enteral feeds, and reduced duration of hospital stay in the probiotics group.

Outdoor and indoor air pollution poses a significant cardiovascular risk, and has been associated with atherosclerosis, the main underlying pathology in many cardiovascular diseases. Although, it is well known that exposure to air pollution causes pulmonary disease, recent studies have shown that cardiovascular health consequences of air pollution generally equal or exceed those due to pulmonary diseases. The objective of this article is to evaluate the current evidence on the emerging role of environmental air pollutions in cardiovascular disease, with specific focus on the types of air pollutants and mechanisms of air pollution-induced cardiotoxicity. Published literature on pollution was systematically reviewed and cited in this article. It is hoped that this review will provide a better understanding of the harmful cardiovascular effects induced by air pollution exposure. This will help to bring a better understanding on the possible preventive health measures and will also serve regulatory agencies and researchers. In addition, elucidating the biological mechanisms underlying the link between air pollution and cardiovascular disease is an essential target in developing novel pharmacological strategies aimed at decreasing adverse effects of air pollution on cardiovascular system.

Pneumomediastinum (PM) is defined as the presence of free air in the mediastinal cavity. It is often regarded as a revealing sign of a more serious medical condition. PM is broken down into two categories, one, with an instigating event, referred to as secondary PM. The other is when free air is discovered in the mediastinal cavity without a clear etiology, referred to as spontaneous pneumomediastinum (SPM). Often misdiagnosed due to the vague nature of presenting symptoms, SPM must be part of the differential diagnosis of a chest pain patient to expedite discovery and if necessary, management. A MedLine/PubMED search was performed identifying all relevant articles with "SPM" in the title. Six case series were reviewed to determine what clinical scenario constitutes a possible case of SPM. Results showed that almost all patients with SPM exhibited some chest pain, but Hamman's crunch was present in only one-fifth of patients. Patients with certain pre-existing pulmonary diseases showed a greater propensity for the presence of free air in the mediastinal cavity. SPM must be diagnosed and managed promptly due to rare, but serious complications and any chest pain with an unknown etiology should contain SPM in the differential diagnosis.

Background: Abdominal trauma is a major public health problem for all nations and all socioeconomic strata. Aim: This study was designed to determine the incidence and patterns of abdominal injuries in trauma patients. Materials and Methods: We classified and identified the incidence and subtype of abdominal injuries and associated trauma, and identified variables related to morbidity and mortality. Results: Abdominal trauma was present in 248 of 300 cases; 172 patients with blunt abdominal trauma and 76 with penetrating. The most frequent type of abdominal trauma was blunt trauma; its most common cause was motor vehicle accident. Among patients with penetrating abdominal trauma, the most common cause was stabbing. Most abdominal trauma patients presented with other injuries, especially patients with blunt abdominal trauma. Mortality was higher among penetrating abdominal trauma patients. Conclusions: Type of abdominal trauma, associated injuries, and Revised Trauma Score are independent risk factors for mortality in abdominal trauma patients.

Background: The spectrum of liver dysfunction in children with dengue infection is wide and has been associated with disease severity. Aims: This study was undertaken to estimate the range of hepatic involvement in dengue infection in children. Materials and Methods: This study assessed the biochemical and clinical profile of hepatic involvement by dengue virus in 120 children with serologically positive dengue fever (DF), aged 2 months to 14 years. Results: All cases were grouped into DF without warning signs (Group 1), DF with warning signs (Group 2) and severe dengue (Group 3) according to revised World Health Organization 2009 criteria. The spectrum of hepatic manifestations included hepatomegaly (80.8%), hepatic tenderness (46.3%), jaundice (60%), raised aspartate transaminase (AST), alanine transaminase (ALT) and prolonged prothrombin time (41.7%) and reduced serum albumin (56%). Conclusions: Hepatic dysfunction was observed more in Groups 2 and 3. There was 84.4% and 93.75% ALT and AST elevation respectively in Group 2 and 94.5% and 95.9% ALT and AST elevation respectively in Group 3 and fulminant hepatic failure was observed in Group 3. Therefore in a child with fever, jaundice, hepatomegaly and altered liver function tests, the diagnosis of dengue infection should be strongly considered in areas where dengue infection is endemic.

Background : Anaemia is estimated to affect half the school-age children and adolescents in developing countries. Aim: This study aimed to determine the prevalence of anaemia and evaluate the relationship of intestinal helminth infection on the anaemia status of children in the rural communities of Evbuomore, Isiohor, and Ekosodin. in the Ovia North East local government area of Edo State, Nigeria. Subjects and Methods : Faecal samples and blood samples were obtained from 316 children aged 1-15 years. Faecal samples were examined using standard parasitological techniques, and anaemia was defined as blood haemoglobin <11 g/dL. Results : Of the 316 children, 38.6% were anaemic: 75.9% of children in Evbuomore, 42.3% in Isiohor and 26.8% in Ekosodin. The overall parasite prevalence in the three communities were: Ascaris lumbricoides (75.6%), hookworm (16.19%) and Trichuris trichiura (7.3%). Malnutrition was patent; 37.0% of the children were stunted, 19.3% wasted, and 44.0% underweight. There was a statistically significant association between hookworm and Ascaris lumbricoides infection and anaemia (P < .001). Serum ferritin levels were more sensitive than haemoglobin in detecting anemia and were correlated with intestinal helminth infection. Conclusion : Intestinal helminth infection in a concomitant state of malnutrition is observed in this population. Intervention programmes should be aimed at control of intestinal helminth infection and iron supplementation.

Background: Morbid obesity has become a common problem worldwide and as a result the demand for bariatric surgery has increased as well. Most patients develop skin redundancy and sagging at many body parts after major weight loss procedures which increased the demand for body contouring procedures. Aims : The study was to address the prevalence and patient's desire for body contouring procedures. Materials and Methods: A cross-sectional study targeting the postbariatric patients from April 2011 to October 2011 was conducted at our hospital. Questionnaire was administered in order to measure frequency and patients desire to undergo body contouring surgery after massive weight loss. Results: The total number of patients was 128 patients. The mean age of our patients was 37-year old (range 18-56 year). The percentage of the desire for body contouring surgery after bariatric surgery was 78.1%. There was very pronounced desire to body contouring surgery after those who underwent gastric bypass surgery with P-value 0.001. Only 18 patients (14%) have underwent body contouring surgery, with a total of 29 procedures, in which abdominoplasty considered the most commonly procedure performed (57%). Conclusion : With the increasing number of weight loss surgery, there is higher number of patients that desire a body contouring surgery, which create huge disparity between demand and accessibility.

Background: Early surgery for appendicitis is thought to avoid complications associated with appendiceal rupture. Aims: This study was to evaluate the effect of timing of surgery on complications, length of stay (LOS) and cost in patients undergoing appendectomy. Materials and Methods: Retrospective review of 396 patients with appendectomies from January 1, 2005 to December 31, 2007 was performed. Demographic data, time of presentation, physical findings, diagnostic data, operating room times, LOS, cost and complications were collected. Patients were divided into 4 groups based on time from presentation to appendectomy. Results: Pathology confirmed appendicitis in 354 (89%) patients. Most patients (90%) had surgery within 18 h of presentation. Timing of surgery did not affect the incidence of purulent peritonitis ( P = 0.883), abscess ( P = 0.841) or perforation ( P = 0.464). LOS was significantly shorter for patients with emergency department registration to operating room times less than 18 h ( P < 0.0001). Costs were significantly higher for patients with times to operating room greater than 18 h ( P < 0.001). Conclusion: Timing of surgery did not affect the incidence of complications or perforated appendicitis. However, delay in surgical consultation and surgery are associated with increased LOS and increased hospital costs. The optimal timing of appendectomy for uncomplicated acute appendicitis appears to be within 18 h of emergency department presentation.

Administration of glucans through immersion, dietary inclusion or injection has been found to enhance many types of immune responses, resistance to bacterial and viral infections and to environmental stress in many fish species. Although the efficacy of the glucan varies with types and administration, glucan used as an immunomodulatory and mostly immunostimulatory additive has been found satisfactory in eliciting immunity in commercial aquaculture. Development of more efficient administration methods will facilitate the routine and prophylactic use of glucans as natural immunostimulants of fish. Using a PubMed search, this review has an extensive literature on glucan in fish immunity.

Background: Obesity is a risk factor for type 2 diabetes mellitus. Insulin resistance is associated with visceral subcutaneous fat content. Neck circumference (NC) is a marker of upper body subcutaneous adipose tissue distribution. Aim: The aim of this study is to compare NC in diabetics and non-diabetics and to correlate NC with other anthropometric measures. Materials and Methods: A cross-sectional study was conducted in 350 type 2 diabetics and 350 non-diabetics of >30 years of age. Anthropometric parameters like body mass index (BMI), waist circumference (WC), hip circumference, and NC were measured. Independent t-test and Pearson's correlation were the tests of significance done to analyze quantitative data. Results: There was positive correlation of NC, BMI, and index of central obesity. The NC in diabetics was significantly higher than in non-diabetics (P < 0.001). NC >36 cm in diabetics and >37 cm in non-diabetics was the best cutoff value to determine subjects with central obesity. Conclusion: The findings indicated that NC may be used both in clinical practice and in epidemiologic studies as a straightforward and reliable index. It is an economical easy to use test with less consumption of time and correlates well with other standard anthropometric parameters.
