Atherogenic index of plasma: A valuable novel index to distinguish patients with unstable atherogenic plaques.

Background: Plaque instability is a leading cause of morbidity and mortality in coronary artery disease (CAD) patients. Numerous efforts have been made to figure out and manage unstable plaques prior to major cardiovascular events incidence. The current study aims to assess the values of the atherogenic index of plasma (AIP) to detect unstable plaques. Materials and Methods: The current case-control study was conducted on 435 patients who underwent percutaneous coronary intervention due to chronic stable angina (stable plaques, n = 145) or acute coronary syndrome (unstable plaques, n = 290). The demographic, comorbidities, chronic medications, biochemical and hematological characteristics of the patients were entered into the study checklist. The baseline AIP was measured according to the formula of triglycerides/high-density lipoprotein logarithm. Binary logistic regression was applied to investigate the standalone association of AIP with plaque instability. Receiver operating curve (ROC) was depicted to determine a cut-off, specificity, and sensitivity of AIP in unstable plaques diagnosis. Results: AIP was an independent predictor for atherogenic plaque unstability in both crude (odds ratio [OR]: 3.677, 95% confidence interval [CI]: 1.521-8.890; P = 0.004) and full-adjusted models (OR: 15, 95% CI: 2.77-81.157; P = 0.002). According to ROC curve, at cut-point level of 0.62, AIP had sensitivity and specificity of 89.70% and 34% to detect unstable plaques, respectively (area under the curve: 0.648, 95% CI: 0.601-0.692, P < 0.001). Conclusion: According to this study, at the threshold of 0.62, AIP as an independent biomarker associated with plaque instability can be considered a screening tool for patients at increased risk for adverse events due to unstable atherosclerotic plaques.

Pulmonary endarteritis and endocarditis complicated with septic embolism: a case report and review of the literature.

BACKGROUND: Pulmonary endarteritis is a rare clinical phenomenon with congenital heart that can potentially lead to major complications. CASE PRESENTATION: We report a 47-year-old man with pulmonary endarteritis. This patient presented with hypertension, chest pain and a previous history of pulmonary valve disease during childhood. Also, eight-months prior, he was hospitalized with dyspnea (Functional Class III), cough, phlegm, and night sweats without fever. Echocardiographic diagnosis in the first transtransthoracic echocardiography (TTE) was intense pulmonary valve stenosis (PVS) an, thus, the pulmonary valve vegetation and PVS, established by transesophageal echocardiography (TEE). He was referred for surgery after 1 weeks of intravenous antibiotic therapy for removal of the vegetation. CONCLUSIONS: Finally he was asymptomatic at 3-months of follow-up and was clinically in good condition. Therefore, the detection of infective endocarditis of the lung valve must not lengthy be prolonged.

Acute changes in cardiac function by direct acting antiviral therapy for hepatitis C-infected patients with thalassemia.

BACKGROUND: Patients with thalassemia may also have cardiac abnormalities due to congenital problems, anemia, and increased burden of iron in their myocardium. This study was designed to evaluate the effects of direct acting antiviral (DAA) therapy on the cardiac function of hepatitis C virus (HCV)-infected patients with thalassemia. METHOD: HCV-infected thalassemia patients were enrolled to this prospective evaluation. Daily tablets of 90 mg Ledipasvir (or 60 mg Daclatasvir) plus 400 mg Sofosbuvir (±ribavirin) were prescribed for the patients according to the Iran Hepatitis Network's guidelines. An echocardiography fellow collected the echocardiography findings before and after the treatment of all the patients. The patients were followed up for any cardiac events within 12 weeks after finishing the treatment. RESULTS: Thirty-two patients with the mean age of 24.2 ± 6.4 years were evaluated. All patients showed a sustained virological response at the 12th week after finishing the treatment. The patients' left ventricular end systolic diameter (3.0 vs 3.24; P = 0.003) and volume (33.8 vs 43.6; P = 0.001), global longitudinal strain of the left ventricle (-22.0 vs -20.6, P = 0.046), and average (-21.4 vs -20.3; P = 0.048), and the right ventricle size (3.12 vs 3.31; P = 0.012) were significantly increased after finishing the treatment. Changes in the abovementioned parameters were not correlated with the patients' myocardium iron load. There were no significant differences in other echocardiographic parameters ( P > 0.05) before and after the treatment. CONCLUSION: Sofosbuvir-based regimens for HCV treatment were safe for our HCV-infected patients with thalassemia. Our patients' ejection fraction remained unchanged. Hence, more specialized echocardiographic evaluations were recommended for those with a history of cardiac abnormalities, cardiac iron overload, and in case of any cardiac adverse event during DAA therapy in patients with thalassemia.

Mutation Screening of KCNQ1 and KCNE1 Genes in Iranian Patients With Jervell and Lange-Nielsen Syndrome.

Background: Jervell and Lange-Nielsen syndrome (JLNS) is an autosomal recessive genetic disease with deafness and QT prolongation. Mutations in KCNQ1 and KCNE1 genes are a cause of JLNS. Our objective was to perform mutational analysis of the KCNQ1 and KCNE1 genes to determine the frequency of mutations in the Iranian population. Material and methods: Fourteen patients and their families were investigated. Mutational screening of the KCNQ1 and KCNE1 genes was performed by a polymerase chain reaction (PCR) followed by direct Sanger sequencing. Results: We identified two frameshift mutations in the KCNQ1 gene, including a novel mutation, c.1356 1356delG, and a known mutation, c.1534_1534delG. A common single nucleotide polymorphism (SNP), c.112G > A, was also found in KCNE1 in seven probands. Conclusion: A novel mutation in the KCNQ1 gene is described. There may be less frequency of mutations in the KCNQ1 and of KCNE1 genes in Iranian JLNS patients compared with other populations.

Long-term right ventricular changes in mustard-exposed patients: A historical cohort.

INTRODUCTION: Mustard gas (MG) is a chemical warfare agent widely used in the Iran-Iraq War. Its catastrophic effects on the lungs, eyes, and skin have been well studied. However, it also affects the cardiovascular system. We aimed to evaluate the long-term effect of MG on right ventricular (RV) function. METHODS: All patients presenting to the university clinics between May 2014 and September 2015 were consecutively evaluated to enter the study based on the inclusion criteria (documented proof of chemical injury, no past or present cardiovascular disease, not a current smoker, and no history of sleep apnea). A comparable control group of veterans without MG exposure was randomly selected. All patients underwent echocardiographic measurement of RV size and function by a blinded cardiologist. RESULTS: We included 23 patients in the MG-exposed group and 19 subjects in the control group, with a mean age of 48.6 years. Mean chemical injury severity score was 29.7% and mean time from the MG exposure was 29.2 years. The main complaint of MG-exposed patients pertained to respiratory symptoms (91%). Pulmonary artery pressure was higher (32.83 vs. 28.95 mmHg) and RV strain was lower (-17.05% vs. -20.72%) in the MG-exposed than in the control group (P < .05). CONCLUSION: Our results present baseline RV values for MG-exposed patients and show mild but significant changes after 3 decades. Further cellular and molecular studies are needed to evaluate underlying mechanisms of MG cardiotoxicity.

Optimizing through computational modeling to reduce dogboning of functionally graded coronary stent material.

Coronary artery disease is the leading cause of death among the men and women. One of the most suitable treatments for this problem is balloon angioplasty with stenting. Functionally graded material (FGM) stents have shown suitable mechanical behavior in simulations. While their deformation was superior to uniform materials, the study was aimed at finding the most suitable configuration to reach the optimum performance. A combination of finite element method (FEM) and optimization algorithm have been used to fulfil this objective. To do that, three different conditions have been investigated in a Palmaz-Schatz geometry, where in the first and second ones the stent was a combination of steel and CoCr alloy (L605), and the third condition was a combination of CoCr alloy (L605) and CoCr alloy (F562). In the first and third conditions, dogboning was the objective function, but in the second condition a non-uniform deformation indicator was chosen as the objective function. In all three conditions the heterogeneous index was the control variable. The stent in the third condition showed a poor performance. While in the steel/CoCr alloy (L605) stents the heterogeneous index of 0.374 showed the lowest maximum dogboning, the heterogeneous index of 5 had more uniform deformation. Overall due to the lower dogboning of the steel/CoCr alloy (L605) stent with heterogeneous index of 0.374, this stent is recommended as the optimum stent in this geometrical configuration.

Methylenetetrahydrofolate reductase C677T and A1298C gene polymorphisms in oral squamous cell carcinoma in south-east Iran.

BACKGROUND: Methylenetetrahydrofolate reductase (MTHFR) gene encodes an essential enzyme involving in folate metabolism. Due to the role of folate in DNA integrity, polymorphisms of MTHFR are interesting targets for cancer risk studies. Our goal was to evaluate the prevalence of MTHFR C677T and A1298T single nucleotide polymorphisms in oral squamous cell carcinoma (OSCC). METHODS: The study was conducted on 57 OSCC patients diagnosed within 2004-2013 along with 62 non-OSCC subjects. DNA was extracted by standard kit protocol. Subsequently, tetra-ARMS (amplification refractory mutation system)-PCR was applied to identify the selected polymorphisms. RESULTS: Data showed that CT and TT genotypes of C677T polymorphisms significantly increased the risk of OSCC [odds ratio (OR) = 2.2, 95% CI: 1-5, P = 0.04]. Although allelic distribution was not significantly different between patients and controls, T allele of C677T polymorphism was closely associated with the risk of OSCC (OR = 2.5; 95% CI: 0.9-6.9; P = 0.07). Results indicated that C677T/A1298C: CC/AC and C677T/A1298C: CC/AA haplotypes were the most common combinations in OSCC patient and control groups, respectively. (OR = 1.5, 95% CI: 0.6-3.8, P > 0.05). CONCLUSION: Our results highlight the possible impact of C677T polymorphism in increasing the risk of OSCC development.

Contribution of Autophagy to Epithelial Mesenchymal Transition Induction during Cancer Progression.

Epithelial Mesenchymal Transition (EMT) is a dedifferentiation process implicated in many physio-pathological conditions including tumor transformation. EMT is regulated by several extracellular mediators and under certain conditions it can be reversible. Autophagy is a conserved catabolic process in which intracellular components such as protein/DNA aggregates and abnormal organelles are degraded in specific lysosomes. In cancer, autophagy plays a controversial role, acting in different conditions as both a tumor suppressor and a tumor-promoting mechanism. Experimental evidence shows that deep interrelations exist between EMT and autophagy-related pathways. Although this interplay has already been analyzed in previous studies, understanding mechanisms and the translational implications of autophagy/EMT need further study. The role of autophagy in EMT is not limited to morphological changes, but activation of autophagy could be important to DNA repair/damage system, cell adhesion molecules, and cell proliferation and differentiation processes. Based on this, both autophagy and EMT and related pathways are now considered as targets for cancer therapy. In this review article, the contribution of autophagy to EMT and progression of cancer is discussed. This article also describes the multiple connections between EMT and autophagy and their implication in cancer treatment.

Assessment of Stiffness-Dependent Autophagosome Formation and Apoptosis in Embryonal Rhabdomyosarcoma Tumor Cells.

Remodeling of the extracellular matrix (ECM) eventually causes the stiffening of tumors and changes to the microenvironment. The stiffening alters the biological processes in cancer cells due to altered signaling through cell surface receptors. Autophagy, a key catabolic process in normal and cancer cells, is thought to be involved in mechano-transduction and the level of autophagy is probably stiffness-dependent. Here, we provide a methodology to study the effect of matrix stiffness on autophagy in embryonal rhabdomyosarcoma cells. To mimic stiffness, we seeded cells on GelMA hydrogel matrices with defined stiffness and evaluated autophagy-related endpoints. We also evaluated autophagy-dependent pathways, apoptosis, and cell viability. Specifically, we utilized immunocytochemistry and confocal microscopy to track autophagosome formation through LC3 lipidation. This approach suggests that the use of GelMA hydrogels with defined stiffness represents a novel method to evaluate the role of autophagy in embryonal rhabdomyosarcoma and other cancer cells.

As an exciting feature, bio-affinity couples, such as proteins with aptamers, ligands, paired nucleotides, and antibodies with antigens, are commonly used as bio-sensitive elements in electrochemical biosensors. Biotin-avidin interactions have been utilized for various purposes in recent years, such as targeting drugs, diagnosing clinically, labeling immunologically, biotechnology, biomedical engineering, and separating or purifying biomolecular compounds. The interaction between biotin and avidin is widely regarded as one of the most robust and reliable noncovalent interactions due to its high bi-affinity and ability to remain selective and accurate under various reaction conditions and bio-molecular attachments. More recently, there have been numerous attempts to develop electrochemical sensors to sense circulating cancer cells and the measurement of intracellular levels of protein thiols, formaldehyde, vitamin-targeted polymers, huwentoxin-I, anti-human antibodies, and a variety of tumor markers (including alpha-fetoprotein, epidermal growth factor receptor, prostate-specific Ag, carcinoembryonic Ag, cancer antigen 125, cancer antigen 15-3, etc.). Still, the non-specific binding of biotin to endogenous biotin-binding proteins present in biological samples can result in false-positive signals and hinder the accurate detection of cancer biomarkers. This review summarizes various categories of biotin-functional nanoparticles designed to detect such biomarkers and highlights some challenges in using them as diagnostic tools.

Carboxymethyl cellulose/sodium alginate hydrogel with anti-inflammatory capabilities for accelerated wound healing; In vitro and in vivo study.

Recently, managing the chronic skin wounds has become increasingly challenging for healthcare professionals due to the intricate orchestration of cellular and molecular processes involved that lead to the uncontrollable inflammatory reactions which hinder the healing process. Therefore, different types of wound dressings with immunomodulatory properties have been developed in recent years to effectively regulate the immune responses, enhance angiogenesis, promote re-epithelialization, and accelerate the wound healing process. This study aims to develop a new type of immunomodulatory wound dressing utilizing carboxymethyl cellulose (CMC)/sodium alginate (Alg)-simvastatin (SIM) to simultaneously enhance the inflammatory responses and the wound healing ratio. The CMC/Alg-SIM hydrogels exhibited appropriate swelling ratio, water vapor transmission rate, and desirable degradation rate, depending on the SIM content. The fabricated dressing showed sustained release of SIM (during 5 days) that improved the proliferation of skin cells. According to the in vitro findings, the CMC/Alg-SIM hydrogel exhibited controlled pro-inflammatory responses (decreased 2.5- and 1.6-times IL-6 and TNF-α, respectively) and improved secretion of anti-inflammatory cytokines (increased 1.5- and 1.3-times IL-10 and TGF-ß, respectively) in comparison with CMC/Alg. Furthermore, the CMC/Alg-SIM hydrogel facilitated rapid wound healing in the rat model with a full-thickness skin defect. After 14 days post-surgery, the wound healing ratio in the CMC/Alg hydrogel group (∼93%) was significantly greater than the control group (∼58%). Therefore, the engineered CMC/Alg-SIM hydrogel with desired immunomodulatory properties possesses the potential to enhance and accelerate skin regeneration for the management of chronic wound healing.
