Abstract
In the past decade and a half, clinical diabetology has undergone enormous development. New drug classes have appeared in everyday practice (GLP1 receptor agonists, SGLT2 inhibitors), which are able to improve the outcome of cardiovascular (macrovascular) complications in diabetes within a few years or even a few months, in contrast to the drugs used in previous large, prospective studies (UKPDS, VADT). The use of thiazolidinediones (including pioglitazone) unfortunately and significantly has declined in recent years, both internationally and domestically, although tested in a randomized, controlled setting (PROactive, 2005), this drug was the first, one might say 'ahead of its time', that significantly reduced the composite clinical endpoint of cardiovascular death, nonfatal myocardial infarction and nonfatal stroke, which became later well-known and took center stage as the 3-point MACE. In this paper, we summarize the most important evidence that accumulated with pioglitazone over the past years. We briefly overview the molecular, cellular and pathophysiological changes it causes, and then, in addition to discussing the cardiovascular, metabolic and other benefits, mention the previously suspected and now confirmed possible side effects. It is our belief that pioglitazone could be successfully used today as part of a combined treatment in properly selected patients, with due care, in the personalized treatment of type 2 diabetes.

Abstract
Gestational diabetes mellitus is one of the most prevalent prenatal illnesses (ranging from 5% to 18%), while intrahepatic cholestasis of pregnancy takes the first place among liver diseases during pregnancy (ranging from 0.2% to 27%). In our summary, we examined the relationship between the two gestation-related medical conditions and their combined presence affects on the outcome of pregnancy. Based on research available, it can be stated that intrahepatic cholestasis of pregnancy may be a predisposing factor to late-onset gestational diabetes mellitus. This connection stems from the modulating role of serum bile acids, as due to the regulation of farnesoid X receptor and Takeda G protein-coupled receptor 5 the bile acids affect glucose and lipid homeostasis. Common fetal complications of gestational diabetes and intrahepatic cholestasis of pregnancy are stillbirth, acute respiratory distress syndrome and preterm delivery. Gestational diabetes mellitus may be more common in patients with intrahepatic cholestasis of pregnancy, and the co-occurrence of the two diseases can increase the risk of fetal and maternal complications, therefore special attention must be paid to the prevention and treatment of these by the prenatal caregiver.

Abstract
BACKGROUND Recent reports suggested a different predictive value for TyG index compared to HOMA-IR in coronary artery calcification (CAC) and other atherosclerotic outcomes, despite that both indices are proposed as surrogate markers of insulin resistance. We hypothesized a key role for liver pathology as an explanation and therefore assessed the relationship among the two indices and the intrahepatic lipid content stratified by PNPLA3 rs738409 genotypes as a known non-alcoholic fatty liver disease (NAFLD) genetic risk. METHODS Thirty-nine women from a prior GDM-genetic study were recalled with PNPLA3 rs738409 CC and GG genotypes for metabolic phenotyping and to assess hepatic triglyceride content (HTGC). 75 g OGTT was performed, fasting lipid, glucose, insulin levels and calculated insulin resistance indices (TyG and HOMA2-IR) were used. HTGC was measured by MR based methods. Mann-Whitney-U, χ2 and for the correlation analysis Spearman rank order tests were applied. RESULTS The PNPLA3 rs738409 genotype had a significant effect on the direct correlation between the HOMA2-IR and TyG index: the correlation (R = 0.52, p = 0.0054) found in the CC group was completely abolished in those with the GG (NAFLD) risk genotype. In addition, the HOMA2-IR correlated with HTGC in the entire study population (R = 0.69, p < 0.0001) and also separately in both genotypes (CC R = 0.62, p = 0.0006, GG: R = 0.74, p = 0.0058). In contrast, the correlation between TyG index and HTGC was only significant in rs738409 CC genotype group (R = 0.42, p = 0.0284) but not in GG group. A similar pattern was observed in the correlation between TG and HTGC (CC: R = 0.41, p = 0.0335), when the components of the TyG index were separately assessed. CONCLUSIONS PNPLA3 rs738409 risk genotype completely decoupled the direct correlation between two surrogate markers of insulin resistance: TyG and HOMA2-IR confirming our hypothesis. The liver lipid content increased in parallel with the HOMA2-IR independent of genotype, in contrast to the TyG index where the risk genotype abolished the correlation. This phenomenon seems to be related to the nature of hepatic fat accumulation and to the different concepts establishing the two insulin resistance markers.

Abstract
Objective To review of the efficacy and safety of pravastatin use for prophylaxis and treatment of preeclampsia. Design Systematic review and meta-analysis of clinical studies evaluating pravastatin for treatment and/or prophylaxis of preeclampsia. Data collection Two independent reviewers systematically searched data from PubMed, Scopus, Web of Science, Cochrane, Embase, and clinicaltrials.gov databases, for studies evaluating pravastatin for prevention of pre-eclampsia. Results Fourteen studies were identified, including 1,570 pregnant women who received either pravastatin or placebo, published between 2003 and 2022. From these studies, 5 studies were identified for inclusion in the meta-analysis to evaluate the role of pravastatin use prior to 20 weeks of gestation, to prevent pre-eclampsia, Pravastatin treatment reduced the incidence of preeclampsia by 61% and premature birth by 45%. Among the newborns, there was a 45% reduction in intrauterine growth retardation (IUGR) in the treated group, as well as a 77% reduction in those receiving neonatal intensive care unit (NICU) admissions. Conclusion Prophylactic treatment with pravastatin appears to reduce risk of developing pre-eclampsia as well as potentially lowering risk of IUGR, preterm birth, and NICU admission in neonates.

Abstract
Pathophysiological alterations in the cochlea and functional tests of the auditory pathway support that in diabetes both vasculopathy and neural changes could be present. The aim of our research was to study the differential effect of type 1 diabetes mellitus (T1DM) on two different age groups. Audiological investigation was carried out in 42 patients and 25 controls at the same age groups. Investigation of the conductive and sensorineural part of the hearing system by pure tone audiometry, distortion product otoacoustic emission measurement and acoustically evoked brainstem response registration were evaluated. Among the 19-39-year-old people the incidence of hearing impairment was not different in the diabetes and control groups. Among the 40-60-year-old people hearing impairment was more common in the diabetes group (75%) than in the control group (15,4%). Among patients with type 1 diabetes, the mean threshold values were higher in both age groups at all frequencies although significant difference was in 19-39 years old group: 500-4000Hz right ear, 4000Hz left ear, in 40-60 years old group: 4000-8000 Hz both ears. In the 19-39 years old diabetes group only at 8000 Hertz on the left side was a significant (p<0,05) difference in otoacoustic emissions. In the 40-60 years old diabetes group significantly less otoacoustic emissions at 8000 Hz on the right side (p<0,01) and at 4000-6000-8000 Hertz on the left side, (p<0,05, p<0,01, p<0,05 respectively) was present compared to the control group. According to ABR (auditory brainstem response) latencies and wave morphologies, a possible retrocochlear lesion arose in 15% of the 19-39 years old and 25% of the 40-60 years old diabetes group. According to our results, T1DM affects negatively the cochlear function and the neural part of the hearing system. The alterations are more and more detectable with aging.

Abstract
Quantitative PCR (qPCR) is used for the determination of gene copy number (GCN). GCNs contribute to human disorders, and characterize copy number variation (CNV). The single laboratory method validations of duplex qPCR assays with hydrolysis probes on CYP21A1P and CYP21A2 genes, residing a CNV (RCCX CNV) and related to congenital adrenal hyperplasia, were performed using 46 human genomic DNA samples. We also performed the verifications on 5 qPCR assays for the genetic elements of RCCX CNV; C4A, C4B, CNV breakpoint, HERV-K(C4) CNV deletion and insertion alleles. Precision of each qPCR assay was under 1.01 CV%. Accuracy (relative error) ranged from 4.96±4.08% to 9.91±8.93%. Accuracy was not tightly linked to precision, but was significantly correlated with the efficiency of normalization using the RPPH1 internal reference gene (Spearman's ρ: 0.793-0.940, p>0.0001), ambiguity (ρ = 0.671, p = 0.029) and misclassification (ρ = 0.769, p = 0.009). A strong genomic matrix effect was observed, and target-singleplex (one target gene in one assay) qPCR was able to appropriately differentiate 2 GCN from 3 GCN at best. The analysis of all GCNs from the 7 qPCR assays using a multiplex approach increased the resolution of differentiation, and produced 98% of GCNs unambiguously, and all of which were in 100% concordance with GCNs measured by Southern blot, MLPA and aCGH. We conclude that the use of an internal (in one assay with the target gene) reference gene, the use of allele-specific primers or probes, and the multiplex approach (in one assay or different assays) are crucial for GCN determination using qPCR or other methods.

Abstract
The human GLUT1 (SLC2A1) membrane protein is the key glucose transporter in numerous cell types, including red cells, kidney, and blood-brain barrier cells. The expression level of this protein has a role in several diseases, including cancer and Alzheimer's disease. In this work, to investigate a potential genetic modulation of the GLUT1 expression level, the protein level was measured in red cell membranes by flow cytometry, and the genetic background was analyzed by qPCR and luciferase assays. We found significant associations between red cell GLUT1 levels and four single nucleotide polymorphisms (SNP) in the coding SLC2A1 gene, that in individuals with the minor alleles of rs841848, rs1385129, and rs11537641 had increased, while those having the variant rs841847 had decreased erythrocyte GLUT1 levels. In the luciferase reporter studies performed in HEK-293T and HepG2 cells, a similar SNP-dependent modulation was observed, and lower glucose, serum, and hypoxic condition had variable, cell- and SNP-specific effects on luciferase expression. These results should contribute to a more detailed understanding of the genetic background of membrane GLUT1 expression and its potential role in associated diseases.

Abstract
Bizonyos nyomelemek ionos, illetve komplexen kötött vegyületei nélkülözhetetlenek
számtalan biokémiai folyamatban, a humán szervezet megfelelő működéséhez.
Hiányuk vagy akkumulációjuk számos egészségügyi problémát, betegséget okoz.
Korábban az inzulinrezisztencia és a cukorbetegség kezelésében a nyomelemeket
kulcsfontosságú faktornak gondolták, azonban a diabetes kialakulásában a
nyomelemek hiánya, fontossága vagy a szövődmények kialakulásában és kezelésében
a nyomelemstatus megítélése, a pótlás fontossága még ma is ellentmondásos. A
szerzők ezért áttekintik a nyomelemek szerepét a diabetes kialakulásában,
patogenezisében és progressziójában. Röviden beszámolnak a cink(II), a
mangán(II, III), a réz(I, II), a króm(III), a vas(II, III), a kobalt(II), a
vanádium(III, IV, V), a molibdén(IV, VI), a jód(I), a szelén(II, IV, VI) és a
lítium(I) humán szervezetben ismert legfontosabb folyamatairól és a diabetesszel
összefüggő biokémiai változásokról. Részletezik a nyomelemstatus eltéréseit
diabetesben, kapcsolatukat a szabad gyökökkel és az antioxidáns védelmi
rendszerrel. Rátérnek néhány rizikófaktor tárgyalására, amely súlyosabb
mikroelemhiányhoz és szövődmények kialakulásához vezet. Orv Hetil. 2022;

Abstract
BACKGROUND TCF7L2 rs7903146 and PNPLA3 rs738409 gene variants confer the strongest risk for type 2 diabetes mellitus (T2DM) and non-alcoholic fatty liver disease (NAFLD), respectively. Pancreatic triacylglycerol content (PTGC) was reported to have a role in T2DM development. We aimed to assess the correlation between PTGC and hepatic triacylglycerol content (HTGC) stratified by PNPLA3 rs738409 genotype and subsequently interactions between PTGC and gene variants associated with β-cell dysfunction (TCF7L2, WFS1) and visceral adiposity (11ΒHSD1) on β-cell function were also tested. METHODS PTGC and HTGC were assessed using MR in a post-hoc analysis of a genotype-based (PNPLA3 rs738409) recall study of 39 (lipid- and glucose lowering) drug-naïve women. Oral glucose tolerance test, HbA1c, insulin indices, anthropometric data were evaluated. The effect of minor allele carrying of TCF7L2 (rs7903146); WFS1 (rs1801214) and 11ΒHSD1 (rs4844880) variants in combination with PTGC was studied on surrogate markers of β-cell function. We used Spearman's rank-order, Mann-Whitney-U tests, and linear regression models. RESULTS PTGC and HTGC values were correlated after stratification by the rs738409 variant (only in CC genotype group R = 0.67, p = 10- 4). PTGC and HbA1c values correlated in the entire study population (R = 0.58, p = 10- 4). Insulin resistance, sensitivity and disposition indices were correlated with PTGC (HOMA2-IR: R = 0.42, p = 0.008; TyG: R = 0.38, p = 0.018; Matsuda: R= - 0.48, p = 0.002; DIbasal: R=-0.33, p = 0.039; ISSI-2: R=-0.35, p = 0.028). Surrogate markers of β-cell function (HOMA2-B, AUCinsulin/AUCglucose) correlated significantly with PTGC in subjects with the following genotypes rs7903146: CC R = 0.51, p = 0.022; rs18001214: CT + CC R = 0.55, p = 0.013; rs4844880: TA + AA R = 0.56, p = 0.016. The strongest interactions were found between PTGC and TCF7L2 rs7903146 effect on HOMA2-B (p = 0.001) and AUCinsulin/AUCglucose (p = 0.013). CONCLUSIONS The PNPLA3 rs738409 genotype has a major effect on the correlation between PTGC and HTGC. Furthermore we first report the combined effect of PTGC and individual risk gene variants of TCF7L2, WFS1 and 11ΒHSD1 on β-cell dysfunction. The correlation between pancreatic lipid accumulation and HbA1c also indicates an important role for the latter pathology.

Abstract
Purpose In diabetic subjects, early visual functional alterations such as color vision deficiencies (CVDs) are known to precede clinically apparent diabetic retinopathy. Prominent photoreceptor outer segment degeneration and an increase in the number of retinal dual cones (co-expressing S- and M-opsins simultaneously) have been described in diabetic rat models, suggesting a connection with the development of CVDs. As cone opsin expression is controlled by thyroid hormones, we investigated the diabetic retina in association with thyroid hormone alterations. Methods In rat models of type 1 and 2 diabetes, dual cones were labeled by immunohistochemistry, and their numbers were analyzed in relation to free triiodothyronine (fT3) and free thyroxine (fT4) levels. Quantification of dual cones was also performed in human postmortem retinas. Additionally, a cross-sectional case–control study was performed where thyroid hormone levels were measured and color vision was assessed with Lanthony desaturated D15 discs. Results A higher number of dual cones was detectable in diabetic rats, correlating with fT4 levels. Dual cones were also present in postmortem human retinas, with higher numbers in the three diabetic retinas. As expected, age was strongly associated with CVDs in human patients, and the presence of diabetes also increased the risk. However, the current study failed to detect any effect of thyroid hormones on the development of CVDs. Conclusions Our results point toward the involvement of thyroid homeostasis in the opsin expression changes in diabetic rats and human samples. The evaluation of the possible clinical consequences warrants further research.

Abstract
BACKGROUND Type 2 diabetes (T2DM) and colorectal cancer (CRC) are both known to modulate gene expression patterns in peripheral blood leukocytes (PBLs). OBJECTIVE As T2DM has been shown to increase the incidence of CRC, we were prompted to check whether diabetes affects mRNA signatures in PBLs isolated from CRC patients. METHODS Twenty-two patients were recruited to the study and classified into four cohorts (healthy controls; T2DM; CRC; CRC and T2DM). Relative expression levels of 573 cell signaling gene transcripts were determined by reverse transcription real-time PCR assays run on low-density OpenArray platforms. Enrichment analysis was performed with the g:GOSt profiling tool to order differentially expressed genes into functional pathways. RESULTS 49 genes were found to be significantly up- or downregulated in tumorous diabetic individuals as compared to tumor-free diabetic controls, while 11 transcripts were differentially regulated in patients with CRC versus healthy, tumor-free and nondiabetic controls. Importantly, these gene sets were completely distinct, implying that diabetes exerts a profound influence on the transcription of signaling genes in CRC. The top 5 genes showing the most significant expression differences in both contexts were PCK2, MAPK9, CCND1, HMBS, TLR3 (p≤0.0040) and CREBBP, PPIA, NFKBIL1, MDM2 and SELPLG (p≤0.0121), respectively. Functional analysis revealed that most significantly affected pathways were cytokine, interleukin and PI3K/Akt/mTOR signaling cascades as well as mitotic regulation. CONCLUSION We propose that differentially expressed genes listed above might be potential biomarkers of CRC and should be studied further on larger patient groups. Diabetes might promote colorectal carcinogenesis by impairing signaling pathways in PBLs.

Abstract
INTRODUCTION Swept-source optical coherence tomography is a useful non-invasive device that is used to understand better the role of choroid in the pathogenesis of diabetic retinopathy. AIM To measure choroidal thickness in diabetic eyes and to correlate it with established systemic risk factors, the severity and the therapy of diabetic retinopathy. METHOD Prospective cross-sectional study using swept-source optical coherence tomography has been performed. Choroidal and macular thickness maps of 117 eyes of 60 diabetic patients were compared to data from 45 eyes of 24 healthy controls. In all diabetic patients, the systemic risk factors (duration and type of diabetes, blood hemoglobin A1C level, hypertension), the type (no, non-proliferative or proliferative) and the therapy of diabetic retinopathy were recorded, and their relation to choroidal thickness was evaluated using multiple regression models. RESULTS A significantly thinner choroid was measured in diabetic patients compared to controls (p<0.05). Analysing the whole cohort, aging (p<0.001) and the presence of hypertension (p<0.05) showed significant correlation with choroidal thinning. In diabetic patients, the duration of diabetes significantly correlated with choroidal thinning (p<0.05). In multivariable analysis, the duration of diabetes remained a significant predictor of choroidal thickness (β -0.18; p = 0.02). A significantly thinner choroid was measured in patients with proliferative retinopathy and in patients after panretinal photocoagulation treatment compared to nonproliferative retinopathy (p<0.05). CONCLUSION Diabetes mellitus itself and diabetic retinopathy progression affects choroidal thickness significantly. Choroidal thickness is affected significantly by systemic risk factors (age, the presence of hypertension, disease duration). Choroidal thinning proved to be correlated with panretinal photocoagulation treatment of diabetic retinopathy. Orv Hetil. 2020; 161(35): 1475-1482.

Abstract
Absztrakt:
Napjainkban az inzulin-túlérzékenységi reakciók az inzulinterápia ritka
mellékhatásának számítanak. Az inzulinallergiának vélt esetek kétharmadában a
tünetek kiváltásáért azonban nem az inzulin a felelős. A szerzők egy inzulinnal
kezelt, 64 éves nőbeteg esetét mutatják be, akinél az inzulinterápia alatt
jelentkező allergiás tünetek hátterét lymphocytatranszformációs teszt (LTT)
segítségével próbálták tisztázni. Vizsgálataik az inzulinnal szembeni
túlérzékenységet nem támasztották alá, ugyanakkor a protaminra pozitív LTT
halallergia gyanúját vetette fel. A kiegészítő immunszerológiai vizsgálatok a
diabetesszel társult, de korábban nem ismert pajzsmirigybetegségre is felhívták
a figyelmet. Tudomásunk szerint ez az első olyan esetismertetés Magyarországon,
amely a feltételezett inzulin-túlérzékenységi reakció valódi okát LTT
segítségével próbálta tisztázni. Orv Hetil. 2020; 161(35): 1483–1487.

Abstract
Introduction: Thrombocytosis and type 2 diabetes have negative effect on the survival of tumor patients. Previously, their joint effect has not been studied in breast cancer. Aim: The aim of our retrospective study was to investigate the occurrence and effects of thrombocytosis and/or type 2 diabetes in breast cancer patients who attended the 2nd Department of Internal Medicine or the 1st Department of Surgery, Semmelweis University, between 2014 and 2017. Laboratory and anamnestic data were compared at the time of tumor diagnosis between diabetic and non-diabetic groups. Survival analysis was performed to study the effects of thrombocytosis and/or type 2 diabetes. Method: 274 study participants were followed until 31 December 2018, or until their last appearance at the University, or until their death. Results: 5% of the patients had elevated platelet counts (over 400 G/L), and 52 were diabetics. Diabetics were significantly older (non-diabetics: 56.8 ± 13.8 years, diabetics: 67.8 ± 11.0 years, p<0.0001). Triple negative subtype (p = 0.0366), and T1 stage (50%) were present more often in non-diabetics. Stage T2 was more common in diabetic patients (51.9%). Type 2 diabetes was associated with a shorter survival time (p = 0.0032). Thrombocytosis did not affect patient survival. Conclusion: At the diagnosis of breast cancer, existing type 2 diabetes is associated with a more severe clinicopathological stage and shorter survival. We recommend that during routine diabetes controls, women should be made aware of the importance of mammography screening. Moreover, diabetes should be considered as a risk factor; after 30 years of age, diabetics should be screened at least every two years. Orv Hetil. 2019; 160(51): 2012-2020.

Abstract
Although insulitis is the characteristic main feature of type 1 diabetes mellitus (T1DM), many aspects of β cell loss still remain elusive. Immune dysregulation and alterations in the dipeptidyl-peptidase-4-incretin system might have a role in disease development, but their connection is poorly understood. We assessed the associations of a few selected, immunologically relevant single nucleotide gene variants with the DPP-4-incretin system in individuals with T1DM and in healthy controls. Prandial plasma (total, active) GLP-1 levels, serum DPP-4 activity, CD25 and CTLA-4 expression of T cells and DPP4 rs6741949, CTLA4 rs3087243, CD25 rs61839660 and PTPN2 rs2476601 SNPs were assessed in 33 T1DM patients and 34 age-, gender-, BMI-matched non-diabetic controls without a family history of T1DM. CTLA-4 expression was lower in the Foxp3+CD25+ regulatory T cells from individuals homozygous for the CTLA4 rs3087243-G variant compared to those who carry an A allele. Prandial plasma total GLP-1 levels 45 min after a standardized meal were reduced in individuals homozygous for the CTLA4 rs3087243 G major allele compared to A allele carriers both in the entire study population (with statistical power over 90%) and within the T1DM group. Here we report for the first time a reduced total prandial GLP-1 plasma concentration in individuals with the CTLA4 rs3087243 G/G genotype. One may speculate that immune response-related L cell damage might possibly explain this novel association.

Abstract
PURPOSE Multiple endocrine neoplasia type 1 is a rare tumor syndrome caused by germline mutations of MEN1 gene. Phenotype varies widely, and no definitive correlation with the genotype has been observed. Mutation-negative patients with MEN1-associated tumors represent phenocopies. By comparing mutation-positive and mutation-negative patients, we aimed to identify phenotype features predictive for a positive genetic test and to evaluate the role of MEN1 mutations in phenotype modulation. METHODS Mutation screeening of MEN1 gene by Sanger sequencing and assessment of clinical data of 189 consecutively enrolled probands and relatives were performed at our national and European Reference Center. Multiple ligation probe amplification analysis of MEN1 gene and Sanger sequencing of CDKN1B were carried out in clinically suspicious but MEN1-negative cases. RESULTS Twenty-seven probands and twenty family members carried MEN1 mutations. Five mutations have not been described earlier. Pronouncedly high number of phenocopies (>70%) was observed. Clinical suspicion of MEN1 syndrome emerged at significantly earlier age in MEN1-positive compared to MEN1-negative probands. Gastroenteropancreatic neuroendocrine tumors developed significantly earlier and more frequently in carriers compared to non-carriers. Probands with high-impact (frameshift, nonsense, large deletions) mutations, predicted to affect menin function significantly, developed GEP-NETs more frequently compared to low-impact (inframe and missense) mutation carriers. CONCLUSIONS MEN1 phenocopy is common and represents a significant confounder for the genetic testing. GEP-NET under 30 years best predicted a MEN1 mutation. The present study thus confirmed a previous proposal and suggested that GEP-NET under 30 years should be considered as a part of the indication criteria for MEN1 mutational analysis.

Abstract
The non-alcoholic fatty liver disease (NAFLD) as a common metabolic disease affects nearly one third of the population in the developed countries. The significance of the NAFLD is due to its spectrum disease (simple steatosis → NASH [non-alcoholic steatohepatitis] ± fibrosis → cirrhosis → HCC [hepatocellular carcinome]) character; its association with obesity, type 2 diabetes mellitus (T2DM), dyslipidaemia, metabolic syndrome, insulin resistance; and its complications both as a consequence of the direct progression of the liver disease and also related to the additional target organ damage due to the progression of the metabolic disease (cardiovascular, renal). The clinical practice guideline jointly authored by 3 European professional societies (EASL-EASD-EASO) in 2016 offers a gap-filling, more united diagnostic, therapeutical and follow-up algorithm for the management of NAFLD. The authors of this article could only aim at highlighting the most important considerations and cite a few important literatures that became available only after the publication of the original article.

Abstract
AIMS To measure choroidal thickness (CT) in diabetic eyes and its correlation with metabolic status and the severity of diabetic retinopathy (DR). MATERIALS AND METHODS Prospective cross-sectional study using swept-source optical coherence tomography. CT maps of 96 treatment naïve eyes of 48 patients with diabetes were compared to 46 eyes of 23 healthy controls. CT changes and their relation to diabetes, age, gender, disease duration, hypertension (HT), hemoglobin A1c level, type and severity of DR were evaluated. RESULTS A significantly thinner choroid was measured in patients with diabetes compared to controls (p < 0.009). In the diabetic group age, gender, disease duration and HT were significantly correlated with CT in univariable regression models (p < 0.05). In multivariable analysis, the duration of diabetes significantly negatively correlated with CT (p = 0.02). According to analysis of variance, there was a significant difference among means of CT in different stages of DR (p = 0.002), with thinner CT in cases with more advanced DR. In a multivariable predictive model, thinner CT was associated with an increased risk for the presence of DR (p = 0.02). CONCLUSIONS Diabetes mellitus itself and the severity of DR affect CT significantly, even after adjusting for the effects of confounding systemic factors. Disease duration seems to be associated with a reduction of choroidal thickness. Decreased CT proved to be correlated with the severity of DR.

Abstract
Although the Human Genome Project discovered the sequence of the human genetic information 15 years ago, genetic background of the diseases - primarily that of complex disorders - is still not known. The sum of the not yet discovered inherited risk factors is termed the missing heritability; the identification of these genetic components is, however, essential, as it is the base of the understanding of the molecular pathomechanism of diseases. It is not only of theoretical importance: this knowledge can be used in the clinical practice, as it offers the possibility of improvement of diagnostics, prevention as well as targeted and individualized therapy. Application of novel and more efficient molecular biological tools contribute to the discovery of unknown genetic factors, the complete goal can only be achieved, however, by re-conceptualization of several clinical and genetic points. Our knowledge was established by genome-wide studies, however, further knowledge must be acquired according to the following points: (1) genotype and association analysis of repeat variations (VNTRs and CNVs) besides SNPs, (2) investigation of gene-gene and gene-environment interactions, (3) epigenetic studies, (4) assessing the biological function of polymorphisms, (5) application of biologically relevant diagnostic categories and endophenotypes. Although it is only 1.2% of the whole genome that codes for proteins, however, as much as 90% is transcribed to RNA, consequently it can be hypothesized that gene expression analyses might offer promising starting points for further studies, as they can shed light on the molecular processes that contribute to the development of diseases.

Abstract
SummaryTemporary ischemia of the rat’s hind paw induces severe thrombohemorrhagic lesions following sensitization by the intravenous injections of ferric dextrin and agar I. Other substances such as India ink and saccharated ferric oxide, which exhibit no thrombohemorrhagic sensitizing properties when a tourniquet, epinephrine or 5-HT are used separately as challengers, prove extremely effective upon application of the tourniquet if epinephrine is also injected into the contralateral paw. Scandium chloride, given intravenously, sensitizes the rat for the production of thrombohemorrhagic lesions by temporary ischemia of the dorsal skin but fails to induce similar changes after an equally severe ischemia of the paw. It is concluded that, following sensitization, two in themselves ineffective agents, can become active thrombohemorrhagic challengers upon conjoint application.

Abstract
INTRODUCTION The relationship between platelets and metastatic tumor cells is an ongoing research area. Pre- and postoperative thrombocytosis are suggested predictive survival markers. Colorectal cancer and type 2 diabetes are characterized by various changes to platelets. The occurrence of colorectal cancer is more frequent in diabetes. AIM Our aim was to determine the occurrence of type 2 diabetes in colorectal cancer patients, who attended the Semmelweis University 2nd Department of Internal Medicine's Oncology Department in the last three years. Further goals included the evaluation of anamnestic, pre- and postoperative laboratory data, and whether diabetes can be a significant survival factor. METHOD A retrospective study was conducted with 86 randomly selected colorectal cancer patients' preoperative (86 patients) and paired postoperative (66, who were operable) data. Patients were monitored no later than September 30, 2017 or until their death. RESULTS Preoperatively, elevated (over 400 Giga/L) platelet counts were present in 22.1% of the patients (323.5 ± 128.63 Giga/L, mean ± SD) which decreased to 10.6% postoperatively (χ2: p = 0.0351; 289.2 ± 82.45 Giga/L, p = 0.0232). Negative correlation was found between platelet counts and overall survival (R: -0.35, p = 0.0085). One third of the patients had diabetes. Laboratory results (i.e., blood counts, creatinine) between diabetic and non-diabetic patients were not significant. Diabetes is a significant five-fold postoperative risk factor for shorter overall survival (relative risk: 5.1612, p = 0.0165). Average survival was 30.6 ± 26.78 months. CONCLUSION Persistent consequential postoperative thrombocytosis may indicate shorter survival time. Our observations suggest elevated platelet counts and type 2 diabetes as prognostic markers for survival at the recognition of colorectal tumors. Orv Hetil. 2018; 159(19): 756-767.

Abstract
The use of metals as biosignatures in the fossil stromatolite record requires understanding of the processes controlling the initial metal(loid) incorporation and diagenetic preservation in living microbialites. Here, we report the distribution of metals and the organic fraction within the lithifying microbialite of the hypersaline Big Pond Lake (Bahamas). Using synchrotron-based X-ray microfluorescence, confocal, and biphoton microscopies at different scales (cm-μm) in combination with traditional geochemical analyses, we show that the initial cation sorption at the surface of an active microbialite is governed by passive binding to the organic matrix, resulting in a homogeneous metal distribution. During early diagenesis, the metabolic activity in deeper microbialite layers slows down and the distribution of the metals becomes progressively heterogeneous, resulting from remobilization and concentration as metal(loid)-enriched sulfides, which are aligned with the lamination of the microbialite. In addition, we were able to identify globules containing significant Mn, Cu, Zn, and As enrichments potentially produced through microbial activity. The similarity of the metal(loid) distributions observed in the Big Pond microbialite to those observed in the Archean stromatolites of Tumbiana provides the foundation for a conceptual model of the evolution of the metal distribution through initial growth, early diagenesis, and fossilization of a microbialite, with a potential application to the fossil record.

Abstract
Diabetes is one of the most common metabolic disorders that may cause pathological pregnancy. Treating diabetes recognized during pregnancy results in lowering maternal and fetal complications. These patients present higher risk for excessive weight gain, preeclampsia, delivery with cesarean sections, high risk of developing type 2 diabetes and cardiovascular disease in the future. Fetuses of mothers with gestational diabetes are at higher risk for macrosomia and birth trauma, after delivery they present higher risk of developing neonatal hypoglycemia, hyperbilirubinemia, and respiratory distress syndrome. There is still no consensus in the recommendations for the diagnosis of gestational diabetes mellitus by expert committees. Orv. Hetil., 2017, 158(8), 283-290.

Abstract
CONTEXT Genetic variation in human maternal DNA contributes to the susceptibility for development of gestational diabetes mellitus (GDM). OBJECTIVE We assessed 77 maternal single nucleotide gene polymorphisms (SNPs) for associations with GDM or plasma glucose levels at OGTT in pregnancy. METHODS 960 pregnant women (after dropouts 820: case/control: m99'WHO: 303/517, IADPSG: 287/533) were enrolled in two countries into this case-control study. After genomic DNA isolation the 820 samples were collected in a GDM biobank and assessed using KASP (LGC Genomics) genotyping assay. Logistic regression risk models were used to calculate ORs according to IADPSG/m'99WHO criteria based on standard OGTT values. RESULTS The most important risk alleles associated with GDM were rs10830963/G of MTNR1B (OR = 1.84/1.64 [IADPSG/m'99WHO], p = 0.0007/0.006), rs7754840/C (OR = 1.51/NS, p = 0.016) of CDKAL1 and rs1799884/T (OR = 1.4/1.56, p = 0.04/0.006) of GCK. The rs13266634/T (SLC30A8, OR = 0.74/0.71, p = 0.05/0.02) and rs7578326/G (LOC646736/IRS1, OR = 0.62/0.60, p = 0.001/0.006) variants were associated with lower risk to develop GDM. Carrying a minor allele of rs10830963 (MTNR1B); rs7903146 (TCF7L2); rs1799884 (GCK) SNPs were associated with increased plasma glucose levels at routine OGTT. CONCLUSIONS We confirmed the robust association of MTNR1B rs10830963/G variant with GDM binary and glycemic traits in this Caucasian case-control study. As novel associations we report the minor, G allele of the rs7578326 SNP in the LOC646736/IRS1 region as a significant and the rs13266634/T SNP (SLC30A8) as a suggestive protective variant against GDM development. Genetic susceptibility appears to be more preponderant in individuals who meet both the modified 99'WHO and the IADPSG GDM diagnostic criteria.

Abstract
As the result of various effects (viruses, metabolic diseases, nutritional factors, toxic agents, autoimmune processes) abnormal liver function, liver steatosis and connective tissue remodeling may develop. Progression of this process is complex including various pathways and a number of factors. The authors summarize the factors involved in the progression of chronic liver disease. They describe the role of cells and the produced inflammatory mediators and cytokines, as well as the relationship between the disease and the intestinal flora. They emphasize the role of oxidative stress, mitochondrial dysfunction and cell death in disease progression. Insulin resistance and micro-elements (iron, copper) in relation to liver damage are also discussed, and genetic and epigenetic aspects underlying disease progression are summarized. Discovery of novel treatment options, assessment of the effectiveness of treatment, as well as the success and proper timing of liver transplantation may depend on a better understanding of the process of disease progression.

Abstract
We assessed the hematopoietic stem and progenitor cell (HSPC) population in the cord blood of neonates born to mothers with gestational diabetes mellitus (GDM) in a hypothesis generating pilot study, due to that, neonatal polycythemia may be the consequence of GDM pregnancy. Forty-five pregnant women with GDM (last trimester mean HbA1C = 33.9 mmol/mol) and 42 (nondiabetic) control pregnant women were enrolled after their routine 75 g oral glucose tolerance test (OGTT) between the 24th and 28th gestational week (with expected differences in their mean routine clinical characteristics: plasma glucose at OGTT: 0′ = 5.07 vs. 4.62 mM, 120′ = 8.9 vs. 5.76 mM, age = 35.07 vs. 31.66 years, prepregnancy body mass index = 27.9 vs. 23.9 kg/m2, GDM vs. control, respectively) on a voluntary basis after signing the informed consent. EDTA-treated cord blood samples were analyzed by flow cytometry and the software Kaluza1.2 using CD45 and CD34-specific fluorescent antibodies to identify the HSPC population (CD34+ cells within the CD45dim blast gate). The proportion of CD34+CD45dim HSPCs among the nucleated cells was significantly (P < 0.05, statistical power = 60.8%) higher in the cord blood samples of neonates born to mothers with GDM (median 0.38%) compared to neonates born to nondiabetic mothers (median 0.32%) and according to treatment types (P < 0.05) median: control 0.32%, GDM-diet only 0.37%, GDM-on insulin 0.45%; control versus GDM on insulin (P < 0.05). The increased proportion of circulating CD34+CD45dim cells in the cord blood may possibly be related to altered fetal stem cell mobilization in GDM pregnancy, yet these results should be interpreted only as preliminary due to the small sample sizes.

Abstract
INTRODUCTION Oxidative-nitrative stress and poly(ADP-ribose) polymerase activation observed in gestational diabetes may play role in the increased cardiovascular risk in later life. AIM The present study aimed to examine the influence of the severity of previous gestational diabetes (insulin need) on vascular function three years after delivery. Furthermore, the authors investigated the relation of vascular function with oxidative-nitrative stress and poly(ADP-ribose) polymerase activation. METHOD Macrovascular function was measured by applanation tonometry; microvascular reactivity was assessed by provocation tests during Laser-Doppler flowmetry in 40 women who had gestational diabetes 3 years before the study. Oxidative-nitrative stress and poly(ADP-ribose) polymerase activity in blood components were determined by colorimetry and immunohistochemistry. RESULTS Three years after insulin treated gestational diabetes impaired microvascular function and increased oxidative stress was observed compared to mild cases. CONCLUSIONS The severity of previous gestational diabetes affects microvascular dysfunction that is accompanied by elevated oxidative stress. Nitrative stress and poly(ADP-ribose) polymerase activity correlates with certain vascular factors not related to the severity of the disease.

Abstract
The absolute or relative lack of insulin is the key factor in the pathogenesis of diabetes mellitus. Although the connection between loss of function mutations of the WFS1 gene and DIDMOAD-syndrome including diabetes mellitus underpins the significance of wolframin in the pathogenesis, exact role of WFS1 polymorphic variants in the development of type 1 and type 2 diabetes has not been discovered yet. In this analysis, 787 patients with diabetes and 900 healthy people participated. Genotyping of the 7 WFS1 SNPs was carried out by TaqMan assays. Association study was performed by χ2-test in combination with correction for multiple testing. For functional analysis, the entire 3' UTR of the WFS1 gene was subcloned in a pMIR-Report plasmid and relative luciferase activities were determined. Linkage disequilibrium analysis showed a generally high LD within the investigated region, however the rs1046322 locus was not in LD with the other SNPs. The two miR-SNPs, rs1046322 and rs9457 showed significant association with T1DM and T2DM, respectively. Haplotype analysis also confirmed the association between the 3' UTR loci and both disease types. In vitro experiments showed that miR-185 reduces the amount of the resulting protein, and rs9457 miRSNP significantly influences the rate of reduction in a luciferase reporter assay. Genetic variants of the WFS1 gene might contribute to the genetic risk of T1DM and T2DM. Furthermore demonstrating the effect of rs9457 in binding of miR-185, we suggest that the optimal level of wolframin protein, potentially influenced by miR-regulation, is crucial in normal beta cell function.

Abstract
Both GLP1(7)(-)(36) (via GLP1 receptor) and the dipeptidyl peptidase-4 (DPP4) cleaved form of GLP1 (GLP1(9)(-)(36), independently of GLP1R) may modulate the response of lymphocytes to cytokine stimuli. The incretin axis, CXCR3 (receptor of DPP4 ligand cytokines CXCL9-11) expression on T(reg)s and hematologic parameters were assessed in 34 patients with long standing type 1 diabetes (T1DM) and in 35 healthy controls. Serum DPP4 (sDPP4) activity, plasma total GLP1 and GLP1(7)(-)(36) concentrations were determined. GLP1(9)(-)(36) concentrations were calculated. CXCR3 expression (flow cytometry) was higher on the CD25(-/)(low)Foxp3(+) than on the CD25(+)Foxp3(+) T(reg)s independently from T1DM, suggesting that CD25(-/)(low)Foxp3(+) T(reg)s are possibly waiting for orientational chemotactic stimuli in a "standby mode". The higher sDPP4 activities in T1DM were inversely correlated with GLP1(7)(-)(36) levels and GLP1(9)(-)(36) levels directly with lymphocyte counts in controls. Our results might indicate an altered DPP4-incretin system and altered immunoregulation including a potentially dysfunctional GLP1(9)(-)(36) signaling in T1DM.

Abstract
BACKGROUND Turner syndrome, a congenital condition that affects 1/2,500 births, results from absence or structural alteration of the second sex chromosome. Turner syndrome is usually associated with short stature, gonadal dysgenesis and variable dysmorphic features. The classical 45,X karyotype accounts approximately for half of all patients, the remainder exhibit mosaicism or structural abnormalities of the X chromosome. However, complex intra-X chromosomal rearrangements involving more than three breakpoints are extremely rare. RESULTS We present a unique case of a novel complex X chromosome rearrangement in a young female patient presenting successively a wide range of autoimmune diseases including insulin dependent diabetes mellitus, Hashimoto's thyroiditis, celiac disease, anaemia perniciosa, possible inner ear disease and severe hair loss. For the genetic evaluation, conventional cytogenetic analysis and FISH with different X specific probes were initially performed. The complexity of these results and the variety of autoimmune problems of the patient prompted us to identify the exact composition and breakpoints of the rearranged X as well as methylation status of the X chromosomes. The high resolution array-CGH (assembly GRCh37/hg19) detected single copy for the whole chromosome X short arm. Two different sized segments of Xq arm were present in three copies: one large size of 80,3 Mb from Xq11.1 to Xq27.3 region and another smaller (11,1 Mb) from Xq27.3 to Xq28 region. An 1,6 Mb Xq27.3 region of the long arm was present in two copies. Southern blot analysis identified a skewed X inactivation with ≈ 70:30 % ratios of methylated/unmethylated fragments. The G-band and FISH patterns of the rearranged X suggested the aspect of a restructured i(Xq) chromosome which was shattered and fortuitously repaired. The X-STR genotype analysis of the family detected that the patient inherited intact maternal X chromosome and a rearranged paternal X chromosome. The multiple Xq breakages and fusions as well as inverted duplication would have been expected to cause a severe Turner phenotype. However, the patient lacks many of the classic somatic features of Turner syndrome, instead she presented multiorgan autoimmune diseases. CONCLUSIONS The clinical data of the presented patient suggest that fragmentation of the i(Xq) chromosome elevates the risk of autoimmune diseases.

Abstract
Summary Our aim was to introduce the Hungarian pilot telemedical screening program for diabetic retinopathy (DRP) and also to evaluate the efficacy of non-mydriatic fundus photographs. A total of 502 eyes of 251 diabetic patients were photographed with a non-mydriatic digital fundus camera in a tertiary diabetology care center. These three 45°-field images were transmitted to the reading center via Internet, where they were graded by two independent ophthalmologists. After non-mydriatic photography (NM method), 28 patients were also examined in mydriasis by an ophthalmologist (O method) and were also photographed in mydriasis (M method). For the comparison of the three methods the kappa statistic was used. With non-mydriatic imaging of 502 eyes no retinopathy was found in 74.5%, DRP was detected in 15.5%, while 10.1% of the photos were ungradable. The rates of DRP severity levels were: 13.55% mild/moderate non-proliferative, 0.59% severe and 1.39% proliferative DRP. Comparing the results of the gradable non-mydriatic photos by the two independent graders, perfect intergrader agreement was found (k = 1.00). The measure of intermethod agreement between NM and M method was also perfect, with a kappa value of 1.00 (grader A and grader B). Based on the results of the O method, there were no misdiagnosed cases nor with the NM-, neither with the M method. Non-mydriatic cameras could be ideal tools of an extended countrywide retinopathy screening program which may serve to reduce the high prevalence of diabetes-related blindness in Hungary.

Abstract
BACKGROUND Tissue-specific dipeptidyl-peptidase 4 (DPP4) dysregulation has been described in adults with diabetes mellitus. The DPP4 -incretin system has not been studied in foetal life. In this study, DPP4 activity and glucagon-like peptide-1 (GLP-1) levels were assessed in cord blood of neonates born to women with gestational diabetes mellitus (GDM) and nondiabetic controls. MATERIAL AND METHODS This study has been conducted in two Hungarian and one Austrian centres. PATIENTS A total of 568 pregnant women were enrolled in the study after their OGTT between the 24th and 28th gestational week. Cord blood samplings with DPP4 activity and GLP-1 level measurements were possible in 270 (DPP4: 159 control, 111 GDM) and 112 (GLP-1: 72 control, 40 GDM) cases. OGTT (24-28th gestational week) and cord blood sampling at delivery were performed. Cord serum DPP4 activity was determined in a continuous monitoring microplate-based kinetic assay, and cord plasma GLP-1 was measured using a fluorescence ELISA method. RESULTS Cord serum DPP4 activity was lower in GDM [mean (95% CI): 28.07 U/L (26.32-29.82 U/L)] than in controls [31.61 U/L (29.93-33.29 U/L), MWU P = 0.0015]. Cord plasma active GLP-1 levels were close to the lower detection limit and were not altered in GDM (control: mean = 3.43 pM, 95% CI: 3.04-3.82 pM, GDM: mean = 3.61 pM, 95% CI: 2.96-4.28 pM - MWU test P = 0.6). CONCLUSIONS Decreased cord serum DPP4 activity in gestational diabetes mellitus might be the result of an adaptive foetal response or an early dysregulation in the entero-insular axis with consequences beyond the incretin system. Cord plasma GLP-1 levels may reflect the missing oral intake with a limited glucose sensing of L cells via the circulation in foetal life.

Abstract
Chromogranin-A is a member of the granine protein family. It is produced in neuroendocrine cells via secretory granules. Many cleavage proteins are formed from chromogranin-A, from which some have well known biological activity, while the function of others is not yet fully known. Serum chromogranin-A levels are used in neuroendocrine tumour diagnostics. Recent studies showed that one of its cleavage protein, WE-14 may also play a role in the development of type 1 diabetes. WE-14 may function as an autoantigen for T-cells involved in the destruction of β-cells. This mechanism was previously observed only in non-obese diabetic mice. Novel results show that WE-14 also serves as a target for autoreactive cells in newly diagnosed type 1 diabetic patients as well, which reaction can be increased with transglutaminase. In this paper the authors summarize the recent knowledge about chromogranin-A and its potential role in the pathomechanism of type 1 diabetes mellitus.

Abstract
In order to reveal impacts of natural and social sciences on each other, the authors examined connections between fields of medical and social sciences using a search for references and citations of scientific publication. 1. The largest affinity between the medical and social sciences was found between neurosciences and psychology, but there was a significant affinity between clinical sciences and general social sciences, as well. 2. The example of General & Internal Medicine papers in the topics of "diabetes" suggests that in the period 2001-2010 the share of references to social sciences was significantly increased. In the meantime, social science papers in the same topics contained references to Clinical Medicine papers in a constantly high percentage. 3. In the sample under study, the age distribution of social science papers in the references did not differ significantly from that of the other sources. 4. Share of references to social science papers was found to be extremely high among Hungarian General & Internal Medicine papers in the topics of "diabetes". This finding still requires clarification, nevertheless, since e.g. it was not supported by an institutional comparison including the largest Hungarian medical research university. 5. The intensity of the reference/citation mediated information flows between the Hungarian Medical Journal, Orvosi Hetilap and social sciences appears to be in accordance with the current international trends.

Abstract
Regulatory T-cells (Treg) have a crucial role in limiting physiologic autoreactivity. Foxp3 is a master regulator transcription factor of Treg differentiation and active Treg cells express high levels of IL-2 receptor α-chain (CD25). The aim of our study was to assess the key markers of Treg cell function in type 1 diabetic (T1DM) and control subjects by flow cytometry. The proportion of CD25(-/low) cells among CD4(+)Foxp3(+) Treg cells was higher in T1DM patients that might suggest a shifted proportion of the incomplete/reserve and the fully active (CD4(+)Foxp3(+)CD25(+)) Treg cell subpopulations in T1DM, similarly to other Th1-mediated autoimmune diseases. In addition to the decreased expression of CD25 and CTLA-4 in T1DM patients, a positive correlation was observed between the CD25 expression on CD4(+) and the CTLA-4 expression in CD8(-) T-lymphocytes both in the T1DM and in the healthy control group. Our results suggest an impaired balance of CD25(+) and CD25(-/low) Treg cells in T1DM which might reflect a decreased late phase peripheral Treg activation even in patients with a mean disease duration of more than a decade.

Abstract
The authors studied trends and patterns in the literature of research labeled as clinical (i.e., having the word "clinical" in their title) in the period between 1991 and 2010. The main findings are: 1. The growth of the literature under study was somewhat stronger than that of the overall medical literature. 2. The dominance of the USA is strong but is challenged by some of the most rapidly developing countries (particularly in the Far-East region: China, Korea) in total production, and by the developed European countries in highly cited publications. The eminence of Italy is remarkable. 3. In comparing the medical fields, the most striking tendencies are the increase of oncology and the attenuation of internal medicine. Surgery is steadily growing in size but decreasing in its citation influence. 4. Word frequency studies support the ever growing weight of oncology and also of genetics. 5. Beyond the thematic changes, word frequency studies also reveal a substantial change in attitude: in the period under study more and more effort was made on emphasizing the usefulness, efficiency and risks of the results in contrast with the more descriptive, investigative approach of the past. The role of therapy is growing, the role of diagnostics is decreasing. The knowledge of these trends and patterns may orient health and science policy makers to cope appropriately with the ever changing world of clinical research.
