Aim: This study sought to investigate the relationship between galectin-3 (Gal-3), myocardial fibrosis (MF) and outcomes in acute heart failure. Materials & methods: The single-nucleotide polymorphisms (SNPs) of LGALS3 at rs4644 and rs4652, plasma Gal-3 level, MF and major adverse events (MAEs) were obtained. Results: There was no significant difference in MAEs when categorizing patients by the LGALS3 SNPs at rs4644 and rs4652. The circulating Gal-3 was related to the degree of MF (p < 0.001). Plasma Gal-3 level and MF can predict an increased risk of MAEs (p < 0.001, p = 0.023, respectively). Conclusion: Not the SNPs of LGALS3 but Gal-3 and MF can predict MAEs in acute heart failure at 1 year of follow-up.

Vitamin D3 Deficiency

This study was carried out to investigate the relationship between common variants in two vitamin D pathway genes (VDR and CYP27B1) and vitamin D3 serum levels. In this study, serum vitamin D metabolite levels were measured in the blood samples of 200 patients with alopecia areata. Then, single nucleotide polymorphisms (SNPs) in VDR and CYP27B1 were analyzed using polymerase chain reaction (PCR)-sequencing. Sixty-three variations were observed in these genes (42 variations in CYP27B1 and 21 variations in VDR). A significant difference in Rs1544410 (odds ratio: 7, P < 0.0005) and rs4646536 (odds ratio: 4.043, P < 0.0005) variants was found between the patients and controls. The study showed the relationship between the two polymorphisms, Rs1544410 (odds ratio: 7, 95% CI, 1–8) and rs4646536 (odds ratio: 4.043, 95% CI, 3–14.038) on the genes VDR and CYP27B1, respectively, with increased risk of developing vitamin D3 insufficiency in the Iranian population. Therefore, SNPs in the VDR and CYP27B1 genes can be considered as prognostic biomarkers of the risk of developing vitamin D3 deficiency.

The Relationship

SummaryHaplotypes of the fibrinogen gamma and alpha (FGG and FGA) genes are associated with the structure of the fibrin network and may therefore influence the risk of stroke. We investigated the relationship between common variation in these genes with ischemic and haemorrhagic stroke. The study was based on 6,275 participants of the prospective population-based Rotterdam Study who at baseline (1990 – 1993) were aged 55 years or over, free from stroke, and had successful assessment of at least one FGG or FGA single nucleotide polymorphisms (SNP). Common haplotypes were estimated using seven tagging SNPs across a 30 kb region containing the FGG and FGA genes. Follow-up for incident stroke was complete until January 1,2005. Associations between constructed haplotypes and risk of stroke were estimated with an age- and sex-adjusted logistic regression model. We observed 668 strokes, of which 393 were ischemic and 62 haemorrhagic, during a median follow-up time of 10.1 years. FGG+FGA haplotype 3 (H3) was associated with an increased risk of ischemic stroke (odds ratio [OR] 1.36, 95% confidence interval [CI] 1.09–1.69) and the risk estimate for hemorrhagic stroke was 0.71 (95% CI 0.46–1.09) compared to the most frequent H1. The FGG and FGA genes were not associated with stroke or its subtypes when analyzed separately. In conclusion, risk of ischemic stroke was higher in FGG+FGA H3 than in H1. The results suggested that an opposite association may exist for haemorrhagic stroke.

Introduction: MPI is an echocardiographic parameter that exibit the left ventricular functions globally. NT-proBNP  is an important both diagnostic and prognostic factor in heart failure. In this study, we aimed to investigate the prognostic significance of serum NT-proBNP levels and MPI in patients with STEMI. Method: Totally 104 patients with a diagnosis of STEMI were included in the study. Patients followed for 30-days and questioned for presence of symptoms of heart failure (HF) and cardiac death. Patients were invited for outpatient control after 30-days and were divided into two groups: (HF (+) group) and (HF (-) group). Results: Totally 104 patients with STEMI were hospitalized in the coronary intensive care unit. Of those patients, 17 were female (16%), 87 were male (84%), and the mean age of the patients was 58.9±10.8 years. During the 30-day follow-up, 28 (27%) of 104 patients developed HF. The mean age, hypertension ratio and anterior STEMI rate were significantly higher in the HF (+) group compared to the HF (-) group. Ejection time (ET) and left ventricular ejection fraction (LVEF) were significantly lower and MPI was significantly higher in the HF (+) group. When the values on day first and  sixth were compared, NT-ProBNP levels were decreased in both groups. There was no significant difference between the two groups in terms of the change in MPI values on the first and sixth days. Multiple regression analysis showed that the presence of anterior MI, first day NT-proBNP level and LVEF were independently associated with development of HF and death. Conclusion: In our study, NT-proBNP levels were found to be positively associated with MPI in patients with acute STEMI. It was concluded that the level of NT-proBNP detected especially on the 1st day was more valuable than MPI in determining HF development and prognosis after STEMI.

Abstract MicroRNAs (miRNAs) and Long non-coding RNAs (lncRNAs) are two major types of non-coding RNAs (ncRNAs) with regulatory roles. Genetic variation in the miRNAs and lncRNAs has been involved in the initiation and progression of many diseases. miRNA-LncRNA interactions are implicated in the regulation of many diseases, such as hepatitis infection. In this study, we assumed that single nucleotide polymorphisms (SNPs) in miR-372 (rs28461391 C/T) and HULC (rs7763881 A/C) might participate in HBV infection risk. SNPs rs28461391 in miR-372 and rs7763881 in HULC were genotyped in 100 HBV patients and 100 healthy controls using the Polymerase chain reaction sequence-specific primer technique (PCR-SSP). Our results showed no significant difference in miR-372 rs12983273 genotype distribution between both controls and HBV patients. On the other hand, there was a significant increase in HULC rs7763881 CC genotype (P<0.05) coincides with a significant decrease in AC genotype distribution (P<0.05) in HBV patients as compared to controls. Our results showed that the CC genotype is associated with an increased risk of HBV infection (OR= 3.43; CI: 1.3-9.07) while AA genotype is a protective one (OR= 0.3; CI: 0.13-9.07). Our results suggest that HULC rs7763881 A/C might be a biomarker for HBV susceptibility. However, larger sample studies are recommended to verify our preliminary data. To the best of our knowledge, the present study was the first to investigate the relevance of miR-372 (rs28461391 C/T) and HULC (rs7763881 A/C) gene polymorphisms to the risk of HBV infection in the Egyptian population.

Background: This study aims to investigate the relation between Survivin gene polymorphisms, and the risk of Hepatocellular carcinoma (HCC) resulting from hepatitis C infection among Egyptian population. Methods: This prospective study was conducted on 164 patients, 57 patients were diagnosed with hepatitis C, where other 57 were diagnosed with HCC in addition to 50 healthy volunteers as controls. Genotyping for Survivin rs1042489 and rs8073069 single nucleotide polymorphisms was carried out by the allelic discrimination Real-Time Polymerase Chain Reaction Single Nucleotide Polymorphisms genotyping technology. Results: The results of Survivin rs1042489 polymorphism, revealed that the TC and CC genotypes were significantly different between hepatocellular carcinoma patients (OR=15.5, 95%CI: 3.299-72.825,P<0.001), and controls (OR=44, 95%CI: 8.025-241.254, P<0.001). Furthermore, CC genotype was significantly different between cirrhotic and hepatocellular carcinoma patients (OR=19.2, 95%CI: 3.097-119.049, P=0.002). Moreover the TC genotype shows a significant different between controls and cirrhotic patients (OR=5.5, 95%CI: 2.111-14.328, P<0.001). However when comparing TT genotypes, CC+TC genotypes results showed a significant association with increasing the risk of cirrhosis and hepatocellular carcinoma (OR=4.812, 95%CI: 1.893-12.233, P=0.001), (OR=21.607, 95%CI: 4.738-98.532, P<0.01), respectively. On the other hand, there was no significant difference among all studied groups for all genotypes, regarding Survivin rs8073069. Also CC+GC genotype showed no significant association with increased the risk of hepatocellular carcinoma (P=0.999) compared with the GG genotypes. Conclusion: The study indicates that functional Survivin rs1042489 polymorphism may contribute to the risk of hepatocellular carcinoma while Survivin rs8073069 polymorphism has no significant association with increased risk of hepatocellular carcinoma among the studied groups.

Surgeons occasionally encounter a case of recurrent hernia in adult patients after the primary repair, and these cases are challenging to manage appropriately. This study was conducted to describe the clinical nature of recurrent inguinal hernia, compare the results of management, and identify the relationship between the specific risk factors and the occurrence of recurrent hernia. Retrospectively reviewed 58 patients who underwent the inguinal herniorrhaphy for recurrent hernia in a single institution. Analyzed clinical characteristics of recurrent hernia and tried to verify the relationship between smoking, obesity, and occurrence of recurrent hernia. Recurrent inguinal hernia was 13.5 per cent of all hernia repairs in the study period. Most of the recurrence was the first event (74.1%) and showed an interval to recurrence with a mean duration of 40.7 months. There was no significant difference in procedure time, development of postoperative complications, and duration of hospital stay according to the procedure. Compromise of smoker and overweight was significantly higher in the recurrent group (P < 0.05). Surgeons should be aware of the increased risk for recurrence in adult inguinal hernia patients when they smoke or are overweight (body mass index ≥ 25 kg/m2), also it needs to follow-up during the adequate period.

Background: Several studies have investigated Galectin-3 as a promising biomarker for predicting the short-term and long-term mortality of patients with acute heart failure. This study aimed to examine the usefulness of plasma galectin-3 at the time of admission in predicting long-term mortality in Vietnamese patients with acute heart failure (AHF). Methods: We carried out a cohort study including 117 patients consecutively diagnosed with acute heart failure in a single cardiology department. Plasma galectin-3 and other biomarkers were measured at the time of admission. The patient’s clinical and analytical characteristics were recorded. The main endpoint was one-year all-cause mortality. Results: There were six patients (5%) lost to follow-up and 59 patients (53.2%) reaching primary outcome within one year after ‎hospital admission.‎ The median plasma galectin-3 level (ng/mL) in patients with acute heart failure was 34.6 (26.7 – 44.1). Plasma galectin-3 in the alive group was significantly higher than that in the deceased group at one-year follow-up. In predicting one-year all-cause mortality, galectin-3 had an area under the curve (AUC) of 0.71 (95% confidence interval (CI), 0.62 – 0.81) representing a good prognostic factor while brain natriuretic peptide (BNP) and troponin I were inferior to galectin-3 with an AUC of 0.69 (95% CI, 0.59 – 0.79) and 0.63 (95% CI, 0.53 – 0.74), respectively. The optimal cut-off value for galectin-3 was 40.75 ng/mL with a sensitivity of 50.1% and a specificity of 88.5%. In a multivariate model, patients with galectin-3 levels > 40.75 ng/mL had a hazard ratio (HR) of 2.8 (95% CI, 1.5 – 5; p = 0.001). The best prediction model was the combined model of galectin-3 and BNP, yielding an AUC of 0.78 (95% CI, 0.70 – 0.86; p < 0.001). Conclusions: Our study suggested that galectin-3 levels could predict long-term all-cause mortality in patients with acute heart failure with a good prognostic capacity. Combining galectin-3 and BNP could bring up a better risk-stratification.

Apoa5 Gene

Background and aims: The APOA5 gene is one of the genes involved in metabolic syndrome (MetS), as a constellation of several cardiovascular disease (CVD) risk factors. The present study evaluated the possible associations between five single nucleotide polymorphisms (SNPs) in the microRNA target site (miR-TS-SNPs) of the APOA5 gene with MetS. Methods: This case-control study included 57 MetS cases, along with 59 normal children and adolescents aged 9-18 years. All miR-TSSNPs rs188133936, rs72525532, rs45596738, rs148759216, and rs114627122 were genotyped by polymerase chain reaction-sequencing. Independent t-test, as well as the chi-square test and logistic regression analysis was used to determine the association of SNPs with MetS risk and its clinical components. Results: The mean (SD) age of MetS participants and controls was 12.35 (0.25) and 13.39 (0.38) years, respectively. Although no nucleotide changes were present in rs188133936, rs45596738, rs148759216, and rs114627122, a greater frequency of A insertion was detected in rs72525532 in MetS cases compared with the control group (P=0.012). This variant showed a significant difference in triglycerides (TG) and high-density lipoprotein cholesterol (HDL) levels between different genotype groups (P<0.0001 and P=0.05, respectively) in controls. Furthermore, AA insertion genotype was correlated with an increased risk of MetS (Odds ratio [95% CI] = 8.12 [0.966-68.27], P=0.05). Conclusion: This study was the first to investigate the association between rs188133936, rs45596738, rs148759216, rs76463524, and rs72525532 variants of the APOA5 gene and MetS. Our findings reveal that rs72525532 might have an impact on TG, HDL levels, and the risk of MetS

Introduction: In recent years, the benefit of early surgery in active infective endocarditis (IE) has been reported. The drawback of early surgery is the risk that residual bacteria in the operative field may cause IE recurrence. Little is known regarding the relationship between intraoperative valve culture and recurrence. In the present study, we investigated the value of early surgery for IE based on the results of valve cultures. Hypothesis: Positive intraoperative valve cultures in early surgery are associated with recurrence. Methods: Between 2009 and 2017, 585 patients underwent valve surgery for definitive left-sided active IE at 14 affiliated hospitals. Early surgery was defined as surgery within 14 days from diagnosis, and patients with unknown valve culture results were excluded. We analyzed the short and mid-term outcome in patients with early surgery (n=228). These 228 patients were compared in two groups: positive (Group P, n=106) and negative (Group N, n=122) valve cultures. The primary outcome was all-cause mortality. Secondary outcomes were recurrence of IE. Mean follow-up time was 2.5±2.8 years. Results: Patients in group P had a significantly higher inflammatory response on preoperative blood tests (White blood cell count: 10.4 (8.3-14.5) vs. 8.2 (6.0-12.7) х10 3 /μl, p=0.005, C-reactive protein: 7.3 (3.8-11.0) vs. 3.8 (2.1-6.8) mg/dl, p<0.001). Patients in group P also had a significantly shorter duration from diagnosis to surgery (2 (1-4) vs. 4 (1-9) days, p<0.001). There was no significant difference in in-hospital mortality between the two groups (13/106 (12%) vs. 11/122 (9%), p=0.43). The overall survival rate at 1 and 5 years was 83% and 69% in group P, 82% and 75% in group N, respectively (p=0.85). The rate of freedom from the recurrence of endocarditis at 1 and 5 years postoperatively was 97% and 82% in group P, and 98% and 92% in group N, respectively (p=0.02). In Cox's hazard analysis, positive valve culture was a risk factor for IE recurrence in multivariate analysis (hazard ratio, 3.39; 95% confidence interval, 1.07 to 10.67; p=0.037). Conclusions: Positive valve culture cases in early surgery for active IE have a significantly increased risk of recurrence compared with valve culture-negative cases and require careful management.

Background: Single Nucleotide Polymorphisms (SNPs) in the Erythropoietin (EPO) promoter region have been shown to influence EPO protein expression, and high blood levels of EPO are associated with an increased risk of brain injury in very preterm infants. Here, we investigated the genotype distributions and association of three EPO gene polymorphisms (rs1617640, rs551238, and rs507392) with the risk of brain injury in preterm infants. Methods: 304 preterm infants with a gestational age of 28 to 34 weeks were enrolled in this study. Brain injury was evaluated by brain ultrasound and MRI examination. EPO gene Single- Nucleotide Polymorphisms (SNPs) were genotyped by the Agena MassARRAY system, and their association with brain injury susceptibility in preterm infants was analyzed. Results: EPO polymorphism rs551238 showed a significant difference in the genotypic distributions between the brain injury group and the control group, and was significantly correlated with reduced susceptibility to brain injury in preterm infants according to the results obtained from both the additive model (OR = 0.520, 95% CI: 0.339-0.799, P = 0.003) and the dominant model (OR = 0.523, 95% CI: 0.332-0.853, P = 0.009). EPO polymorphisms rs1617640 and rs507392 did not meet the Hardy-Weinberg equilibrium in the study population (P < 0.05) and were, thus, not subjected to further analysis for their impacts on brain injuries. Conclusion: The “C” allele of rs551238 was correlated with a reduced risk of brain injury in preterm infants which may serve as a potential marker for brain injury prediction in preterm infants.
