The FTO AA genotype, independently from its effect on BMI, is associated with measures of ethanol consumption and possibly tobacco smoking.

BackgroundDiabetic foot is a serious condition in patients with a long lasting diabetes mellitus. Diabetic foot treated improperly may lead not only to delayed ulceration healing, generalized inflammation, unnecessary surgical intervention, but also to the lower limb amputation. The aim of this study was to compare diabetic foot risk factors in population with type 2 diabetes and risk factors for diabetes in healthy subjects.MethodsThe study included 900 subjects: 145 with diabetic foot, 293 with type 2 diabetes without diabetic foot and 462 healthy controls matched in terms of mean age, gender structure and cardiovascular diseases absence. Study was conducted in Gastroenterology and Metabolic Diseases Department, Medical University of Warsaw, Poland. In statistical analysis a logistic regression model, U Mann-Whitney’s and t-Student test were used.ResultsThe binomial logit models analysis showed that the risk of diabetic foot in patients with type 2 diabetes was decreased by patient’s age (odds ratio [OR] = 0.94; 95% confidence interval [CI]: 0.92-0.96; p = 0.00001) and hyperlipidaemia (OR = 0.54; 95% CI: 0.36-0.81; p = 0.01). In contrast, male gender (OR = 2.83; 95% CI: 1.86-4.28; p = 0.00001) diabetes duration (OR = 1.04; 95% CI: 1.03-1.06; p = 0.0003), weight (OR = 1.04; 95% CI: 1.03-1.06; p = 0.00001), height (OR = 1.08; 95% CI: 1.05-1.11; p = 0.00001) and waist circumference (OR = 1.028; 95% CI: 1.007-1.050; p = 0.006) increase the risk of diabetic foot. The onset of type 2 diabetes in healthy subjects was increased by weight (OR = 1.035; 95% CI: 1.024-1.046; p = 0.00001), WC (OR = 1.075; 95% CI: 1.055-1.096; p = 00001), hip circumference (OR = 1.03; 95% CI: 1.01-1.05; p = 0.005), overweight defined with body mass index (BMI) above 24,9 kg/m2 (OR = 2.49; 95% CI: 1.77-3.51; p = 0.00001) and hyperlipidaemia (OR = 3.53; 95% CI: 2.57-4.84; p = 0.00001).ConclusionsRisk factors for Type 2 diabetes and diabetic foot are only partially common. Study proved that patients who are prone to developing diabetic foot experience different risk factors than patients who are at risk of diabetes. Identification of relationship between diabetic foot and diabetes risk factors in appropriate groups may help clinicians to focus on certain factors in diabetic foot prevention.

INTROduCTION Diabetic foot is a severe diabetic complication, which may result in ulcerations that are unresponsive to treatment and in lower limb amputation. Osteoprotegerin is a protein that is involved in the pathogenesis of diabetic foot.

Despite the use of Hymenolepis diminuta as a model organism in experimental parasitology, a full genome description has not yet been published. Here we present a hybrid de novo genome assembly based on complementary sequencing technologies and methods. The combination of Illumina paired-end, Illumina mate-pair and Oxford Nanopore Technology reads greatly improved the assembly of the H. diminuta genome. Our results indicate that the hybrid sequencing approach is the method of choice for obtaining high-quality data. The final genome assembly is 177 Mbp with contig N50 size of 75 kbp and a scaffold N50 size of 2.3 Mbp. We obtained one of the most complete cestode genome assemblies and annotated 15,169 potential protein-coding genes. The obtained data may help explain cestode gene function and better clarify the evolution of its gene families, and thus the adaptive features evolved during millennia of co-evolution with their hosts.

The etiology of common complex diseases is multifactorial, involving both genetic, and environmental factors. A role for mitochondrial dysfunction and mitochondrial DNA (mtDNA) variation has been suggested in the pathogenesis of common complex traits. The aim of this study was to investigate a potential role of mtDNA variants in the development of obesity, diabetes, and atherosclerosis in the Polish population. Whole mtDNA sequences from 415 Polish individuals representing three disease cohorts and a control group were obtained using high-throughput sequencing. Two approaches for the assessment of mtDNA variation were applied, traditional mitochondrial haplogroup association analysis and the mutational or variant load model using the MutPred pathogenicity prediction algorithm for amino acid substitutions in humans. We present a possible association between mildly deleterious mtDNA variant load and atherosclerosis that might be due to having more than one likely mildly deleterious non-synonymous substitution. Moreover, it seems largely dependent upon a few common haplogroup associated variants with MutPred score above 0.5.

The existence of the specific factors influencing Charcot neuroarthropathy development may result in earlier identification of patients at risk of its development. There is a necessity to take special care for patients prone to develop Charcot neuroarthropathy in order to prevent its occurrence and severe complications.

INTRODUCTION    Early detection of diabetic retinopathy (DR) is crucial for preventing irreversible blindness. Recent studies identified some of the genetic factors involved in the pathology of DR, although their precise underlying mechanisms remain unclear. OBJECTIVES    This pilot study aimed to determine genetic predictors of DR among patients with type 2 diabetes (T2D) and diabetic foot (DF) based on pathogenetic pathways. PATIENTS AND METHODS    The study included 114 patients with T2D and DF (64 with DR, 50 without DR). Genetic analysis was performed for each patient and the following alterations were analyzed: rs759853 (AKR1B1), rs1800469 (TGFB1), rs2073618 and rs3134069 (TNFRSF11B), rs6330 and rs11466112 (NGF), rs1801133 (MTHFR), rs8192678 (PPARGC1A), rs1799983 (NOS3), rs1553005 (CALCA), and rs121917832 (CDKN1B). RESULTS    Correlations with DR were identified for the following single nucleotide variants (SNVs): rs759853, rs2073618, and rs3134069. Carriers of the G allele of the rs759853 variant had a higher risk of DR in the dominant model (odds ratio [OR], 3.0; 95% confidence interval [CI], 1.15-7.81; P = 0.02). We analyzed 2 SNVs of the osteoprotegerin gene (rs3134069 and rs2073618), and found that the A allele of the rs3134069 variant decreased the risk of DR in both the recessive and additive models (OR, 3.33; 95% CI, 1.07-10.3; P = 0.04). Conversely, there were fewer carriers of the C allele of the rs2073618 variant in patients with DR in the dominant model (OR, 0.28; 95% CI, 0.09-0.92; P = 0.04). CONCLUSIONS    The results of our study suggest that the SNVs rs759853, rs3134069, and rs2073618 may be involved in the development of DR in patients with T2D and DF.
