ABSTRACT

OBJECTIVE: To evaluate whether a nationwide prenatal anomaly screening programme improves detection rates of univentricular heart (UVH) and transposition of great arteries (TGA), and whether maternal risk factors for severe fetal heart disease affect prenatal detection. DESIGN: Population-based cohort study. SETTING: Nationwide data from Finnish registries 2004-14. POPULATION: A total of 642 456 parturients and 3449 terminated pregnancies due to severe fetal anomaly. METHODS: Prenatal detection rates were calculated in three time periods (prescreening, transition and screening phase). The effect of maternal risk factors (obesity, in vitro fertilisation, pregestational diabetes and smoking) was evaluated. MAIN OUTCOME MEASURES: Change in detection rates and impact of maternal risk factors on screening programme efficacy. RESULTS: In total, 483 cases of UVH and 184 of TGA were detected. The prenatal detection rate of UVH increased from 50.4% to 82.8% and of TGA from 12.3% to 41.0% (P < 0.0001). Maternal risk factors did not affect prenatal detection rate, but detection rate differed substantially by region. CONCLUSIONS: A nationwide screening programme improved overall UVH and TGA detection rates, but regional differences were observed. Obesity or other maternal risk factors did not affect the screening programme efficacy. The establishment of structured guidelines and recommendations is essential when implementing the screening programme. In addition, a prospective screening register is highly recommended to ensure high quality of screening. TWEETABLE ABSTRACT: Implementation of a nationwide prenatal anomaly screening improved detection rates of UVH and TGA.

ABSTRACT

We investigated whether chorioamnionitis affects immunohistochemical demonstration of RECK protein and interleukin-6 (IL-6) expression in fetal placental membranes following late preterm delivery with intact membranes. Fetal membranes of 28 women with single pregnancy, preterm delivery and histologically documented chorioamnionitis at gestational age 34-366/7 weeks constituted the chorioamnionitis study group. The control group consisted of 28 fetal membranes from women with preterm deliveries at the same gestational age without histological chorioamnionitis. Immunohistochemistry was performed using monoclonal antibodies against RECK protein and IL-6. We found a statistically significant difference in RECK expression between the chorioamnionitis and control groups; however, we found no difference in IL-6 expression between the groups. We demonstrated that RECK expression is down-regulated in fetal membranes from pregnancies with spontaneous late preterm birth and intact membranes, which suggests its role in preterm parturition. Equal expression of IL-6 in fetal membranes of pregnancies with and without histological chorioamnionitis is an intriguing and unexpected observation that requires further investigation.

ABSTRACT

OBJECTIVE: To evaluate the association of amniotic fluid (AF) matrix metalloproteinase-8 (MMP-8) and cathelicidin concentrations with microbial invasion of the amniotic cavity (MIAC) in pregnancies with preterm prelabor rupture of the membranes or intact membranes. STUDY DESIGN: Amniocentesis was performed in 54 singleton pregnancies between 22+0 and 34+2 gestational weeks with suspected intra-amniotic infection. AF-MMP-8 was analysed by immunoassay and AF-cathelicidin by commercial ELISA. Standard biochemical methods, molecular microbiology and culture techniques were used. RESULTS: MIAC was present in 18 (33%) women. The cutoff value for the diagnosis of MIAC was 41.5 ng ml-1 for AF-MMP-8, and 11.6 ng ml-1 for AF-cathelicidin. With these cutoff values AF-MMP-8 had a sensitivity of 100%, specificity of 69%, positive predictive value of 62% and negative predictive value of 100% for MIAC. The corresponding values for AF-cathelicidin were 89, 81, 70 and 94%. CONCLUSION: The performance of AF-cathelicidin in the prediction of MIAC is comparable to AF-MMP-8.

ABSTRACT

OBJECTIVE: The objective of this study was to evaluate the association of amniotic fluid lactate dehydrogenase and glucose concentrations with microbial invasion of amniotic cavity and histologic chorioamnionitis before 37 pregnancy weeks in women with or without preterm premature rupture of membranes. STUDY DESIGN: Amniocentesis was performed on 70 women with suspected intra-amniotic infection. Standard biochemical methods, molecular microbiology and culture techniques were used. Histopathological examination of the placenta was performed. RESULTS: Thirty (48%) women had microbial invasion of the amniotic cavity (MIAC), 53 (76%) women had histological chorioamnionitis and 28 women had both. The cutoff values for MIAC and histological chorioamnionitis were 429 IU l(-1) for lactate dehydrogenase and 0.7 mmol l(-1) for glucose. Both end points occurred equally often regardless of the membrane status. CONCLUSION: Increased amniotic fluid lactate dehydrogenase and decreased glucose were associated with MIAC and histological chorioamnionitis. However, test performance was of limited value.

ABSTRACT

BEN is a primary, chronic tubulointerstitial nephritis characterized with chronic anemia, absence of edema, xantoderma, normal blood pressure and normal findings on the fundus oculi. The disease is distributed in restricted areas in Bulgaria, Romania, Croatia, Bosnia, Former Yugoslavia. Despite numerous studies on genetic and environmental factors and their possible involvement in BEN, its etiopathogenesis still remains elusive. Our recent study aim to elucidate the possible epigenetic component in BEN development. Whole genome DNA array methylation analysis was applied to compare the methylation profiles of male and female BEN patients from endemic regions in Bulgaria and Serbia and healthy controls. All three most prominent candidate genes with aberrations in the epigenetic profile discovered with this study are involved in the inflammatory/immune processes and oncogenesis. These data are in concordance with the reported pathological alterations in BEN. This research supports the role of epigenetic changes in BEN pathology. Exome sequencing of 22.000 genes with Illumina Nextera Exome Enrichment Kit revealed three mutant genes (CELA1, HSPG2, and KCNK5) in BEN patients which encode proteins involved in basement membrane/extracellular matrix and vascular tone, tightly connected to process of angiogenesis. We suggest that an abnormal process of angiogenesis plays a key role in the molecular pathogenesis of BEN.

ABSTRACT

OBJECTIVE: To assess the long-term neurodevelopmental outcome of children born from singleton euploid pregnancies with increased fetal nuchal translucency (NT) in the first trimester ultrasound screening and without structural anomalies in the second trimester ultrasound screening. STUDY DESIGN: This is a register-based retrospective cohort study carried out at a tertiary referral centre from 2002 to 2007. Children were followed up until 2012. All fetuses had increased NT (>95th percentile) at the first trimester ultrasound screening and normal findings in the second trimester ultrasound screening. Data about the neurodevelopmental outcome was retrieved from the hospital databases, The National Institute for Health and Welfare, and the Finnish Causes of Death Statistics Database. Information about received disability allowances was gathered from the Social Insurance Institute of Finland. RESULTS: The study population consists of 691 children. The mean follow-up time was 6.5 years. Neurodevelopmental disorders occurred in 29 children (4.2%). Twelve of these 29 children (1.7%) had severe neurodevelopmental impairment. CONCLUSIONS: The long-term neurodevelopmental outcome of children after increased fetal NT is reassuring. This information should be added to the parental counselling of such cases. © 2014 John Wiley & Sons, Ltd.

ABSTRACT

Balkan endemic nephropathy (BEN) is a familial chronic tubulointerstitial disease with insidious onset and slow progression leading to terminal renal failure. The results of molecular biological investigations propose that BEN is a multifactorial disease with genetic predisposition to environmental risk agents. Exome sequencing of 22 000 genes with Illumina Nextera Exome Enrichment Kit was performed on 22 DNA samples (11 Bulgarian patients and 11 Serbian patients). Software analysis was performed via NextGene, Provean, and PolyPhen. The frequency of all annotated genetic variants with deleterious/damaging effect was compared with those of European populations. Then we focused on nonannotated variants (with no data available about them and not found in healthy Bulgarian controls). There is no statistically significant difference between annotated variants in BEN patients and European populations. From nonannotated variants with more than 40% frequency in both patients' groups, we nominated 3 genes with possible deleterious/damaging variants--CELA1, HSPG2, and KCNK5. Mutant genes (CELA1, HSPG2, and KCNK5) in BEN patients encode proteins involved in basement membrane/extracellular matrix and vascular tone, tightly connected to process of angiogenesis. We suggest that an abnormal process of angiogenesis plays a key role in the molecular pathogenesis of BEN.

ABSTRACT

Balkan endemic nephropathy (BEN), a familial chronic tubulo-interstitial disease with a slow progression to terminal renal failure, affects people living in the alluvial plains along the tributaries of the Danube River. One of its most peculiar characteristics is a strong association with upper urothelial cancer. An increased incidence of upper urinary tract (UUT) transitional cell cancer (TCC) was discovered among the inhabitants of endemic settlements and in families affected by BEN. In areas where BEN is endemic, the incidence of upper tract TCC is significantly higher, even 100 times, than in non-endemic regions. A high incidence of urothelial cancer in end-stage BEN patients strongly suggests preventive nephro-ureterectomy in all end-stage patients with BEN treated with either transplantation or dialysis. Better understanding of the molecular mechanisms involved in carcinogenesis and tumor progression, has provided a large number of molecular markers of TCC, with a potential diagnostic and prognostic value. Markers that distinguish among TCC, normal urothelium, and benign urothelial conditions are potentially diagnostic, prognostic, and therapeutic targets. The geographic correlation and presence of AA-DNA adducts in both BEN and associated urothelial cancer, support the speculation that these diseases share a common etiology. Dietary exposure to AA is a significant risk factor for BEN and its attendant transitional cell cancer. These are cases of well-known AA induced urothelial carcinoma, and could be detected worldwide. The presence of more than one risk factors is possible and it is important to test etiological hypotheses in different endemic foci, preferably as a multicentric research.

ABSTRACT

Management of post-partum haemorrhage (PPH) involves the treatment of uterine atony, evacuation of retained placenta or placental fragments, surgery due to uterine or birth canal trauma, balloon tamponade, effective volume replacement and transfusion therapy, and occasionally, selective arterial embolization. This article aims at introducing pregnancy- and haemorrhage-induced changes in coagulation and fibrinolysis and their relevant compensatory mechanisms, volume replacement therapy, optimal transfusion of blood products, and coagulation factor concentrates, and briefly cell salvage, management of uterine atony, surgical interventions, and selective arterial embolization. Special attention, respective management, and follow-up are required in women with bleeding disorders, such as von Willebrand disease, carriers of haemophilia A or B, and rare coagulation factor deficiencies. We also provide a proposal for practical instructions in the treatment of PPH.

ABSTRACT

The spatial and temporal pattern of appearance of pro-apoptotic caspase-3 and p53 proteins, and anti-apoptotic bcl-2 protein was investigated in the developing pituitary gland of 6 human embryos 5-8-weeks old, using morphological and immunohistochemical techniques. Their dynamic appearance was analyzed in the Rathke's pouch (future adenohypophysis), mesenchyme, and in the developing neurohypophysis. In the 5th and 6th week, caspase-3 positive cells appeared in the Rathke's pouch (5%) and stalk (11%), in the mesenchyme, but not in the neurohypophysis. In the 6th and 7th week, apoptotic cells were more numerous in the caudal part of the Rathke's pouch due to its separation from the oral epithelium. Pro-apoptotic p53 protein was detected in all parts of the pituitary gland throughout the investigated period. Nuclear condensations characterized cells positive to caspase-3 and p53 proteins. Apoptotic cells displayed condensations of nuclear chromatin on an ultrastructural level as well. While caspase-3 dependent pathway of cell death participated in morphogenesis of the adenohypophysis and associated connective tissue, p53-mediated apoptosis most likely participates in morphogenesis of all parts of the gland, including neurohypophysis. The anti-apoptotic bcl-2 protein was also detected in all parts of the developing gland. With advancing development, the positivity to bcl-2 protein increased in the cells of the adenohypophysis, while it decreased in the neurohypophysis. Bcl-2 protein probably prevented cell death in all parts of the gland and enhanced cell differentiation. The described pattern of appearance of the investigated pro-apoptotic and anti-apoptotic factors might be important for normal morphogenesis and function of the pituitary gland.

ABSTRACT

PURPOSE: This study was designed to evaluate prospectively the results of the overlap technique in primary sphincter reconstruction after obstetric tear. METHODS: Obstetric tears in 44 women were operated on with primary overlap reconstruction. These women were investigated six to nine months after the operation. Results were compared with those of a historical control group of 52 women whose obstetric sphincter rupture had been treated with the end-to-end technique. RESULTS: The overlap group had significantly more incontinence symptoms after delivery and repair of the sphincter tear than before delivery (P < 0.0001); however, their incontinence symptoms were significantly fewer than those of the end-to-end group (P = 0.004). The prevalence of persistent rupture of the external anal sphincter was significantly lower in the overlap group (6/44, 13.6 percent) than in the end-to-end group (39/52, 75 percent; P < 0.0001). Internal anal sphincter rupture occurred in 5 patients (11.4 percent) in the overlap group and in 40 patients (76.9 percent) in the end-to-end group (P < 0.0001). CONCLUSIONS: The overlap technique should be adopted as the method of choice for primary sphincter repair after obstetric tear.

ABSTRACT

AIM: To re-examine serum complement and immunoglobulin levels in patients with Balkan Endemic Nephropathy (BEN) in the early stage of the disease; to study autoantibodies (anti-thyroid, anti-smooth muscle, anti-mitochondrial, anti-parietal, anti-nuclear, and anti-DNA) in these patients; and, finally, to re-asses the immunohistology in kidney biopsies from BEN patients. A review of the immunological studies in BEN will be presented. METHODS: Forty-five BEN patients in the early stage of disease, from the South Morava Region, were included in this study. Fifty-five apparently healthy controls, matched for age and sex, from the neighbouring control villages were selected. Serum complement and immunoglobulin levels were determined by the Immunochemistry system of Beckman. Auto-antibodies were detected in the sera by the indirect fluorescence method or by radio-immunoassay (anti-single stranded DNA). Immunofluorescent microscopy was used for kidney samples treated with FITC conjugated antisera for IgG, IgM, IgA, C3, C1q, C4 and fibrin/fibrinogen. RESULTS: Serum C3 was decreased in the sera of patients with BEN compared to healthy controls (p < 0.001), serum IgM was also decreased (p < 0.05). Anti-thyroid antibodies were detected in 5/45 BEN patients, anti-parietal in 7/45 patients and ANA in 2 BEN patients. No anti-smooth muscle, anti-mitochondrial, or anti-DNA antibodies were detected in any BEN patient. Immunofluorescent studies of 10 kidney biopsy specimens showed rare, unspecific, focal, mesangial deposits of C3 and IgM in some glomeruli, and rare deposits, mostly of C3, in tubuli and extraglomerular vessels. CONCLUSION: Humoral immune mechanisms do not appear to play a pathogenetic role in BEN. A few studies on cell-mediated immunity in BEN were performed, and further studies are needed on patients in the early stage of the disease.

ABSTRACT

Generation of reactive oxygen species significantly contribute to the pathogenesis of renal injury induced by myoglobin release. The present study was performed to investigate the effects of dietary curcumin, a natural antioxidant isolated from plant Curcuma longa, in an experimental model of myoglobinuric acute renal failure. Rats received curcumin at an oral dose of 100mg/kg/day for 30 days. Renal injury was induced with injection of hypertonic glycerol (10 ml/kg 50% solution) in hind limb muscle with blood urea of 57.8+/-7.2 vs. 7.72+/-1.03 mmol/l and serum creatinine of 444.4+/-61.3 vs. 51.8+/-10.6 micromol/l, in glycerol-induced acute renal failure (ARF) vs. control rats, respectively. After 48 h rats were sacrificed and thiobarbituric acid reactive substance (TBARS), glutathione, carbonyl content and kidney cortex brush border peptidase activities were determined in serum, kidney and liver. Rats that received curcumin in addition to glycerol had significantly lower TBARS in serum but not in kidney and liver. Carbonyl content in kidney and liver was significantly elevated in curcumin and glycerol treated rats and improved in animals treated with curcumin and glycerol together. The activities of kidney cortex enzymes, aminopeptidase N, angiotensinase A and dipeptidyl peptidase IV, were reduced in glycerol as well as in curcumin treated rats. The results obtained in this study provided additional evidence that despite its limited antioxidant activity curcumin did not protect kidney in myoglobinuric model of ARF.

ABSTRACT

UNLABELLED: Studies on the outcome of hemodialysis (HD) patients over time have mainly focused on morbidity and mortality, but currently, the importance of measuring the patient's health-related quality of life (HRQoL) is being increasingly recognized. On the other hand, comorbidity is the single most important determinant of outcome in patients on HD. The aims of this study were to evaluate HRQoL in patients at the initiation of HD therapy (incident cohort), and in patients on long-term HD treatment (prevalent cohort), and to establish the relationship between the presence of comorbidity and patient's HRQoL. The study enrolled 229 patients on HD, divided into two groups: prevalent cohort comprised 192 patients on chronic HD more than 3 months, and incident cohort with 37 patients who started their dialysis during the study. Comorbidity was assessed using the Index of Coexistent Diseases (ICED), including two sub-indexes: Index of Disease Severity (IDS), a medical record review of 16 medical conditions, and Index of Physical Impairment (IPI), an observer-based assessment of 11 physical functions. ICED scores range from 0 to 3, with higher levels reflecting more severe comorbidity. Patient's self-assessment of HRQoL was measured by the 36-item Short Form Health Survey Questionnaire (SF-36), encompassing 8 summary scales and 2 summary dimensions. Based on the ICED index level, in both groups of patients (prevalent and incident group), a high presence of associated diseases was observed, i.e. 56.8 % and 67.6 % respectively. Indicators of comorbidities have negative and statistically significant correlation, so that any increase of IDS and IPI indexes produces significant decrease of HRQoL parameters. HRQoL summary scales in both groups of patients were similar, but generally with lower values in incident subjects and with statistical significance only in social functioning (SF) scale (40.5 +/- 24.9 vs 51.0 +/- 27.2). In the incident group of patients, one year of HD treatment was associated with a slight improvement in all HRQoL parameters, but statistical significance (p < 0.05) was observed only in the role-physical limitation (RP) scale and SF scale. CONCLUSIONS: In the patients on HD treatment, comorbid conditions have negative and statistically significant correlation with parameters of HRQoL, and could explain poor HRQoL to a remarkable extent. One year after starting HD, patients reported better scores in some domains, especially in the RP and SF scale. From a clinical perspective, parameters of HRQoL and comorbidities should be considered in the follow up of patients treated with HD.

ABSTRACT

The main objective of this paper was to evaluate the efficacy and safety of the management of pediatric urolithiasis by extracorporeal shock wave lithotripsy (ESWL). Between November 1988 and July 2000, 165 renal stones, 53 ureteral stones, and 5 bladder stones were treated in 126 pediatric patients using Siemens Lithostar lithotriptor. The ESWL treatments ranging from 1 to 7 were needed per patient (mean: 2.1). One ESWL session was performed for 49.6% of stones, two for 24.6%, three for 13.0 %, four for 5.6% and > 4 for 8.2%. The success rate for renal stone units (asymptomatic fragments less than 4 mm) was 88.2%, stone-free rate was 49.0%. The stone-free rate for ureteral stone units was 87.5%, but was 75% for bladder stones. The overall results of ESWL treatment in 126 children was satisfactory: the success rate was 90.5%, stone-free rate was 51.6%, residual fragments > 4 mm were 9.5%. General anesthesia was required in 65 children (136 treatments) under the age of 10, and only in 18 children (40 treatments) in the age 11-14. Auxiliary procedures, such as double J stent and percutaneous nephrostomy (PCN) were used in 19 and 7 patients, respectively. Perirenal hematoma in one patient and hematomas in enteric wall in another one patient were the only major complications managed conservatively without consequences. Low energy lithotripsy with the Siemens Lithostar in our series of pediatric patients was safe and relatively effective.

ABSTRACT

OBJECTIVE: Lymphocyte 5'-nucleotidase is sensitive to superoxide anion, and is an indicator of oxidative stress in humans. The aim of this study was to assess the effect of the sulfonylurea drugs gliclazide and glibenclamide on lymphocyte ecto-5'-nucleotidase of type 2 diabetic patients. METHODS: Thirty obese type 2 diabetic patients were treated for three months after randomisation either with gliclazide or glibenclamide. Basic laboratory parameters (glycaemia, fructosamine, C-peptide), plasma malondialdehyde levels (MDA) as well as lymphocyte 5'-nucleotidase activity were determined, for all patients and 16 healthy controls, before and after the treatment. RESULTS: 5'-nucleotidase activity in diabetic patients before treatment with gliclazide was 1.61 +/- 0.16 nmol/min/10(6) lymphocytes, and was significantly (P < 0.01) increased compared with the level in healthy controls. After three months of gliclazide treatment, ecto-5'-nucleotidase activity fell significantly by 47.39% and 36% in unstimulated Con A- and PMA-stimulated lymphocytes, respectively. Glibenclamide treatment had no effect on ecto-5'-nucleo-tidase of type 2 diabetic patients. Glycoregulation was improved, as plasma fructosamine decreased from 53.4 to 42.1 and from 50.5 to 43.4 U/g proteins after gliclazide and glibenclamide treatment, respectively. Plasma MDA levels markedly decreased after gliclazide but not glibenclamide treatment. CONCLUSION: These results show that gliclazide treatment inhibits the activity of lymphocyte ecto-5'-nucleotidase and presumably de-creases the concentration of adenosine at the cell surface. A decrease in 5'-nucleotidase activity and attenuation of adenosine production may be a factor in the protection of tissue injury in type 2 diabetic patients.

ABSTRACT

AIM: The aim of this study was to investigate the effects of regular aerobic execise on glycaemic control, insulin resistance, cardiovascular risk and oxidative stress-defense parameters in overweight and obese type 2 diabetic patients. METHODS: Changes from baseline to 3 and 6 months of aerobic exercise in total of 30 type 2 diabetics were assessed for physical activity index (PAI), fasting glycaemia (FG), glycated hemoglobin (HbA(1c)), median blood glucose (MBG), insulin resistance (HOMA), triglycerides (TG), cholesterol, the Ashwell Shape Chart Health Risk, SCORE risk, body mass index (BMI), waist and hip circumference, systolic (SBP) and diastolic (DBP) blood pressure, plasma and erythrocyte malondialdehyde (MDA), glutathione, sulphydryl groups and catalase (CAT) and were compared to the results of 30 healthy control subjects. RESULTS: At baseline, significant differences were recorded between the control and diabetes group for FG (P<0.001), HOMA (P<0.001), SBP and DBP (P<0.001), TG (P<0.01), MDA(pl) (P<0.01), CAT (P<0.01) and SCORE risk (P<0.001). Significant changes within the diabetes group were found for PAI (P<0.05), FG (P<0.001), MBG (P<0.05), HbA(1c)(P<0.05), HOMA (P<0.01), SBP and DBP (P<0.001) from baseline to 3 months, as well as for FG (P<0.01), HOMA (P<0.001), SBP and DBP (P<0.05) from 3 to 6 months. Significant (P<0.05) correlations were found for FG and PAI (R=0.432), as well as for HOMA and both HbA(1c)(R=0.412) and SCORE risk (R=-0.387) in the diabetes group. CONCLUSION: Regular aerobic exercise has beneficial effects on glycaemic control, insulin resistance, cardiovascular risk, oxidative stress-defense parameters in overweight and obese type 2 diabetics.

ABSTRACT

The presence of antiphospholipid antibodies is associated with thromboembolic events, thrombocytopenia and numerous pregnancy complications such as recurrent miscarriage, preeclampsia and HELLP syndrome. This condition is known as the antiphospholipid syndrome (APS). We describe a rare case of recurrent liver necrosis postpartum in two consecutive pregnancies of woman with systemic lupus erythematosus (SLE) and positive antiphospholipid antibodies (aPL) who underwent complete recovery.
