A New Treatment Strategy that Reduces Growth/Differentiation Factor-15 in Type-2 Diabetes Mellitus: Major Autohemotherapy: A Pilot Study.

Context: Growth/differentiation factor-15 (GDF-15) is a diagnostic and prognostic marker associated with inflammation, renal damage, and cardiovascular risk in type-2 diabetes mellitus. Researchers have proposed treatment targets that reduce GDF-15 levels. Objective: Our aim in this study is to investigate the effect of major autohemotherapy on GDF-15 levels and to evaluate it as a complementary therapy. Design: The research team designed a laboratory study to examine the effect of major hemotherapy on GDF-15 levels in patients with type-2 diabetes mellitus and healthy volunteers. Blood was drawn from the participants in a closed system, infused with ozone gas, and reinfused into the patients. Setting: The study was carried out from 15 August-5 October at Kirsehir Training and Research Hospital Traditional and Complementary Medicine Center, Turkey. Participants: The study was conducted prospectively, and two groups were formed, consisting of those with type-2 diabetes mellitus (n = 21) and healthy volunteers (n = 14). Outcome Measures: All participants received 10 sessions of major autohemotherapy at a concentration of 25-35 micrograms/milliliter twice a week. Before and after the application, GDF-15, fasting glucose, glycosylated hemoglobin, and lipid panel levels were studied and compared. Results: Age, GDF-15, fasting glucose, glycosylated hemoglobin, and triglyceride levels were found to be higher in the type-2 diabetes mellitus group compared to the healthy group, and high-density lipoprotein cholesterol levels were found to be lower. After major autohemotherapy, GDF-15 and low-density lipoprotein cholesterol decreased significantly in the type-2 diabetes mellitus group. No change was observed in the healthy group. Conclusions: As a new treatment strategy, major autohemotherapy reduces GDF-15 levels in type-2 diabetes mellitus and contributes to the therapeutic effects of ozone therapy.

Bleeding complications during cardiac electronic device implantation in patients receiving antithrombotic therapy: is there any value of local tranexamic acid?

BACKGROUND: The perioperative use of antithrombotic therapy is associated with increased bleeding risk after cardiac implantable electronic device (CIED) implantation. Topical application of tranexamic acid (TXA) is effective in reducing bleeding complications after various surgical operations. However, there is no information regarding local TXA application during CIED procedures. The purpose of our study was to evaluate bleeding complications rates during CIED implantation with and without topical TXA use in patients receiving antithrombotic treatment. METHODS: We conducted a retrospective analysis of consecutive patients undergoing CIED implantation while receiving warfarin or dual antiplatelet (DAPT) or warfarin plus DAPT treatment. Study population was classified in two groups according to presence or absence of topical TXA use during CIED implantation. Pocket hematoma (PH), major bleeding complications (MBC) and thromboembolic events occuring within 90 days were compared. RESULTS: A total of 135 consecutive patients were identified and included in the analysis. The mean age was 60 ± 11 years old. Topical TXA application during implantation was reported in 52 patients (TXA group). The remaining 83 patients were assigned to the control group. PH occurred in 7.7 % patients in the TXA group and 26.5 % patients in the control group (P = 0.013). The MBC was reported in 5.8 % patients in the TXA and 20.5 % patients in control group (P = 0.024). Univariate logistic regression analysis identified age, history of recent stent implantation, periprocedural spironolactone use, periprocedural warfarin use, perioperative warfarin plus DAPT use, cardiac resynchronization therapy, and topical TXA application during CIED implantation as predicting factors of PH. Multivariate analysis showed that perioperative warfarin plus DAPT use (OR = 10.874, 95 % CI: 2.496-47.365, P = 0.001) and topical TXA application during CIED procedure (OR = 0.059, 95 % CI: 0.012-0.300, P = 0.001) were independent predictors of PH. Perioperative warfarin plus DAPT use and topical TXA application were also found to be independent predictors of MBC in multivariate analyses. No thromboembolic complications was recorded in the study group. CONCLUSION: The present study demonstrated that the topical TXA application during CIED implantation is associated with reduced PH and MBC in patients with high bleeding risk.

COHgb levels predict the long-term development of acute myocardial infarction in CO poisoning.

BACKGROUND: There are several studies evaluating the cardiac effects of carbon monoxide (CO) poisoning during the acute period; however, the number of studies evaluating the long-term cardiac effects is limited. OBJECTIVE: The present study aimed to evaluate the effects of blood carboxyhemoglobin (COHb) levels, elevated due to CO poisoning on the long-term development of acute myocardial infarction (AMI). METHODS: This cross-sectional cohort study included a total of 1013 consecutive patients who presented to the emergency department (ED) due to CO poisoning, between January 2005 and December 2007. The diagnosis of CO poisoning was made according to the medical history and a COHb level of greater than 5%. In terms of AMI development, the patients were followed up for an average of 56 months. RESULTS: At the end of follow-up, 100 (10%) of 1013 patients experienced AMI. Carboxyhemoglobin levels at the time of poisoning were higher among those who were diagnosed with AMI compared to those who were not (55%±6% vs 30%±7%; P<.001). Using a multivariate Cox proportional hazards model with forward stepwise method, age, COHb level, CO exposure time, and smoking remained associated with an increased risk of AMI after adjustment for the variables found to be statistically significant in a univariate analysis. According to a receiver operating characteristic curve analysis, the optimal cutoff value of COHb used to predict the development of AMI was found to be greater than 45%, with 98% sensitivity and 94.1% specificity. CONCLUSION: In patients presenting to the ED with CO poisoning, COHb levels can be helpful for risk stratification in the long-term development of AMI.

Higher cancer antigen 125 level is associated with the presence of permanent atrial fibrillation in systolic heart failure patients.

INTRODUCTION: Atrial fibrillation (AF) is a common arrhythmia in heart failure (HF). Recent studies have shown that serum cancer antigen-125 (CA-125) levels are elevated in HF, and high levels of CA-125 in HF patients with sinus rhythm have been shown to be associated with the development of new onset AF. However, the relation between CA-125 levels and the presence of AF in HF is unknown. In this study we investigated whether plasma CA-125 levels in patients with systolic HF could predict the presence of AF. METHODS: The study was a retrospective cohort design including 205 stable systolic HF patients who were selected during outpatient clinic visits and who had CA-125 measurement and an electrocardiogram within the last one month before admittance to cardiology clinic. Patients were classified into two groups based on the presence of AF (n = 67) or sinus rhythm (n = 138). RESULTS: The mean age of the patients was 68 ± 11 years. CA-125 levels were significantly higher in patients with AF than patients with SR [33 (3-273) vs 102 (7-296) U/ml, P < 0.001]. CA-125 level, presence of right ventricular dilatation, pericardial effusion, moderate to severe TR and MR, and left atrial diameter were found to be associated with the presence of AF in univariate analysis. In a multivariate logistic regression model, only the CA-125 level remained associated. Also, according to the ROC curve analysis, the optimal cut-off level of CA-125 for predicting AF was ≥ 91 U/mL with a specificity of 84% and a sensitivity of 54%. CONCLUSION: We have shown that the CA-125 levels can be used to predict AF in patients with systolic HF.

Cancer antigen-125 levels predict long-term mortality in chronic obstructive pulmonary disease.

BACKGROUND: Cancer antigen-125 (CA-125) might be a useful biomarker to predict long-term mortality in patients with recent exacerbation of chronic obstructive pulmonary disease (COPD). METHODS: A total of 87 consecutive patients with COPD were evaluated prospectively. Mean age of patients was 68 ± 10 years (55% males, 45% females) with a median follow-up period of 49 months. Optimal cut-off value of CA-125 to predict mortality was found as >93.34 U/ml, with 91% specificity and 40% sensitivity. RESULTS: After follow-up, 20 out of 87 (23%) experienced cardiovascular death. CA-125 levels were higher among those who died compared to those who survived [55 (12-264) versus 28 (5-245) U/ml, p = 0.013]. In multivariate Cox proportional-hazards model with forward stepwise method, only CA-125 > 93.34 U/ml on admission (HR = 3.713, 95% CI: 1.035-13.323, p = 0.044) remained associated with an increased risk of death. CONCLUSIONS: For the first time, we demonstrated that CA-125 helps the risk stratification of patients with COPD.

Preventing amikacin related ototoxicity with N-acetylcysteine in patients undergoing peritoneal dialysis.

Amikacin is a frequently used antibiotic in the treatment of peritoneal dialysis (PD)-related peritonitis. Ototoxicity is a well-known complication of amikacin for which increased oxidative stress and free oxygen radicals are thought to be responsible. In this study, the effect of N-acetyl-cysteine (NAC) on cochlear function and oxidant situation in the amikacin related ototoxicity in PD-related peritonitis patients are investigated. Forty-six patients who had their first PD-related peritonitis attacks receiving empirical amikacin treatment were enrolled in the study. The patients were randomized into two groups; the first group (n = 23) as NAC receiving and the second group (n = 23) as a placebo receiving, control group. Otoacoustic emissions were measured before, 1 week after and 4 weeks after the treatment. Oxidative stress measurements were performed concurrently in order to evaluate the effectiveness of NAC. The results of screening with otoacoustic emission testing after amikacin treatment showed that cochlear function is protected especially in higher frequencies in NAC group when compared with the control group. Evaluation of the antioxidant status of the two groups showed no differences in the basal values, but at the first week there was an increase in the NAC group compared with the control group, and this increase became significant at the fourth week. NAC is found to be safe and effective in amikacin-related ototoxicity in patients with PD-related peritonitis. We suggest a close monitoring of the patients receiving amikacin containing treatment protocols and if amikacin is administrated supplementing the treatment with NAC.

Lymphocytopenia is associated with poor NYHA functional class in chronic heart failure patients with reduced ejection fraction.

OBJECTIVE: In heart failure (HF) patients, functional capacity has been demonstrated to be a marker of poor prognosis, independent of left ventricular ejection fraction (EF). Lymphocyte count is currently recognized in certain risk stratification scores for chronic HF, and severe HF is associated with lymphocytopenia. However, no data exists on the association between lymphocyte count and functional capacity in patients with stable HF. This study aimed to assess the relationship between lymphocyte count and New York Heart Association (NYHA) functional capacity in systolic HF outpatients. METHODS: The Turkish Research Team-HF (TREAT-HF) is a network which undertakes multi-center observational studies in HF. Data on 392 HF reduced ejection fraction (HFREF) patients from 8 HF centers are presented here. The patients were divided into two groups and compared: Group 1 comprised stable HFREF patients with mild symptoms (NYHA Class I-II), while Group 2 consisted of patients with NYHA Class III-IV symptoms. RESULTS: Patient mean age was 60±14 years. Lymphocyte count was lower in patients with NYHA functional classes III and IV than in patients with NYHA functional classes I and II, (0.9 [0.6-1.5]x1000 versus 1.5 [0.7-2.2]x1000, p<0.001). In multivariate logistic regression analysis, lymphocyte count (OR: 0.602, 95% CI: 0.375-0.967, p=0.036), advanced age, male gender, presence of hypertension, EF, left atrium size, systolic pulmonary artery pressure, neutrophil and basophil counts, creatinine level, and diuretic usage were associated with poor NYHA functional class in systolic HF outpatients. CONCLUSION: The present study demonstrated that in stable HFREF outpatients, lymphocytopenia was strongly associated with poor NYHA function, independent of coronary heart disease risk factors.

Usefulness of admission gamma-glutamyltransferase level for predicting new-onset heart failure in patients with acute coronary syndrome with left ventricular systolic dysfunction.

OBJECTIVES: Our aim was to determine whether there is a relationship between admission gamma-glutamyltransferase (GGT) and subsequent heart failure hospitalizations in patients with acute coronary syndrome. STUDY DESIGN: We selected 123 patients with newly diagnosed acute coronary syndrome of ejection fraction (EF) <45%. Patients were followed 15±10 months, and the relationship between admission GGT level and hospitalization because of heart failure during the follow-up was examined. RESULTS: Twenty-three (18.7%) patients were hospitalized during the follow-up of 15±10 months. Receiver operating characteristic (ROC) curve analysis showed that the cut-off point of admission GGT related to predict hospitalization was 49 IU/L, with a sensitivity of 81.7% and specificity of 65.2%. Increased GGT >49 IU/L on admission, presence of hypertension and hyperlipidemia, left ventricular ejection fraction (LVEF), right ventricular dysfunction, moderate-to-severe mitral regurgitation, alanine aminotransferase level, and antiplatelet agent usage were found to have prognostic significance in univariate Cox proportional hazards analysis. In multivariate Cox proportional-hazards model, increased GGT >49 IU/L on admission (hazard ratio [HR] 2.663, p=0.047), presence of hypertension (HR 4.107, p=0.007), and LVEF (HR 0.911, p=0.002) were found to be independent factors to predict new-onset heart failure requiring hospitalization. CONCLUSION: Hospitalization in heart failure was associated with increased admission GGT levels. Increased admission GGT level in acute coronary syndrome with heart failure should be monitored closely and treated aggressively.

Atrial fibrillation is associated with increased mean platelet volume in patients with type 2 diabetes mellitus.

Platelet abnormalities in diabetes mellitus (DM) and atrial fibrillation (AF) may underline the etiology of a prothrombotic state in these conditions. Increased mean platelet volume (MPV) is a marker of abnormal platelet function and activation. We aimed to investigate the possible association of chronic AF with MPV in patients who have type 2 DM. Patients who had type 2 DM with either chronic (≥6 months) AF or normal sinus rhythm (NSR) were included in the study. A total of 162 patients (aged 38-89 years) were divided into 2 groups according to the presence of either AF or NSR. Group 1 consisted of 81 diabetic patients with AF, and group 2 consisted of 81 diabetic patients with NSR. The two groups were not significantly different in terms of age, and gender, as well as in hypertension, smoking, history of coronary artery disease, previous cerebrovascular accidents, microalbuminuria, retinopathy, duration of DM, body mass index, hemoglobin A1c, total cholesterol, low-density lipoprotein cholesterol, high-density lipoprotein cholesterol, and triglyceride (p > 0.05 for all variables). Although no significant difference was present between groups concerning platelet count; for patients with AF, MPV was higher compared with patients with NSR (9.0 ± 0.2 fl vs. 8.4 ± 0.2 fl; p = 0.001). Furthermore, no significant difference was noted between groups regarding routine medications received by patients. In multivariate logistic regression analysis, MPV was the only variable independently related to AF (OR = 2.659; 95% CI, 1.286-5.498; p = 0.008). Consequently, it is concluded that AF is associated with increased MPV in patients with type 2 DM, suggesting the presence of tentatively related processes leading to reciprocal interaction.

Atypical antipsychotic use is an independent predictor for the increased mean platelet volume in patients with schizophrenia: A preliminary study.

BACKGROUND: Cardiovascular diseases, cardiovascular risk factors, and mortality due to these situations are more frequently encountered in schizophrenic patients when compared with the general population. The mean platelet volume (MPV) is a surrogate biomarker of the platelet activity and an useful prognostic test in cardiometabolic diseases. The aim of this study was to investigate what influenced MPV levels in patients with schizophrenia. MATERIALS AND METHODS: We evaluated hospital records of 60 hospitalized schizophrenia patients. Thirty age- and sex-matched healthy control subjects were also included as a control group. RESULTS: MPV levels were significantly higher in patients who were on atypical antipsychotic drugs than in patients who were not using any drug (9.2 ± 0.8 vs. 8.6 ± 0.8 fL, P = 0.016) and also higher than control group (9.2 ± 0.8 vs. 8.1 ± 0.9 fL, P < 0.001). Furthermore, patients who were not using antipsychotics had higher MPV than control group (8.6 ± 0.8 vs. 8.1 ± 0.9 fL, P = 0.036). Atypical antipsychotic use [Odds ratio (OR) =6.152, 95% confidence interval (CI,) P = 0.003)] and platelet distribution width (OR = 0.989, 95% CI, P = 0.032) were associated with high MPV levels in univariate analysis. In multivariate logistic regression model, only atypical antipsychotics use (OR = 6.152, 95% CI, P = 0.003) was found to be independent predictor of high MPV levels after adjustment of other potential confounders (age, gender, presence of hypertension, diabetes mellitus, hyperlipidemia, and smoking). CONCLUSION: MPV seems to be influenced not only by schizophrenia itself but also by atypical antipsychotic drugs. It might be concluded that schizophrenic patients are under increased risk for cardiometabolic diseases and risk factors and this risk is higher in patients on atypical antipsychotic treatment.

The Effect of Waste Ballast Aggregates on Mechanical and Durability Properties of Standard Concrete.

The acquisition and transportation of aggregate exacerbate the negative impact of concrete on the environment, and waste materials are considered an effective solution to this crucial problem. One of these waste materials is waste ballast (WB), which is needed for new infrastructure along with increasing rail track technology. In this study, the effect of WB aggregate (which is basalt-based) on the mechanical and durability properties of standard concrete was examined. Coarse aggregate was replaced with WB aggregate at the rates of 50%, 75% and 100%. The slump, compressive strength, flexural strength, capillary water absorption, rapid chloride permeability and water penetration tests on the mixtures were performed. According to the results of this study, the utilization of WB improved the compressive strength and flexural strength of the mixtures by about 15% and 7%, respectively. Moreover, the capillary water absorption, rapid chloride permeability and water penetration values of all the concrete mixtures with WB were lower than the control mixture. In addition, the correlation relations between the mechanical and durability properties indicated that they have a strong relationship with each other. All the results of this study demonstrated that the utilization of WB instead of coarse aggregate improved the mechanical and durability properties of concrete. WB can also provide a more sustainable material formation by minimizing the negative environmental effects of concrete production.

Increased d-dimer levels predict cardiovascular mortality in patients with systolic heart failure.

D-dimer is a fibrin degradation product, and is implicated in pathologies of cardiovascular system. Thrombosis within the vascular system in relation with inflammation and stasis might be associated with poor prognosis in patients with systolic heart failure (HF). In this study we aimed to investigate for relationship between d-dimer levels and cardiovascular mortality in patients with systolic HF. A total of 174 consecutive patients with hospitalized systolic HF were evaluated. All hospitalized patients were obtained d-dimer levels within the first 24 h following admission after obtaining informed consent. Patients were followed up for cardiovascular mortality and 40 (23%) patients died. d-dimer levels were higher among those who died compared to those who survived (2727 ± 2569 (710-4438) versus. 1029 ± 1319 (303-1061) ng/ml, P < 0.001). Optimal cut-off level of d-dimer to predict cardiovascular mortality was found to be >1435 ng/ml. D-dimer levels were negatively correlated with ejection fraction, positively correlated with left atrium size and left ventricular diastolic diameter. D-dimer >1435 ng/ml, age, diabetes mellitus, presence of atrial fibrillation, and creatinine level were found to have prognostic significance in univariate analyses. In multivariate Cox proportional-hazards model, d-dimer > 1435 ng/ml (HR = 3.250, 95% CI 1.647-6.414, P = 0.001), creatinine level (HR = 1.269, 95% CI 1.008-1.599, P = 0.043), and presence of atrial fibrillation (HR = 2.159, 95% CI 1.047-4.452, P = 0.037) remained associated with an increased risk of death after adjustment for variables found to be statistically significant in univariate analysis and correlated with d-dimer level. In conclusion, d-dimer measurement could help risk stratification in patients with systolic HF.

Increased γ-glutamyl transferase levels predict early mortality in patients with acute pulmonary embolism.

BACKGROUND: Increased γ-glutamyl transferase (GGT) level is associated with increased oxidative stress, all-cause mortality, the development of cardiovascular disease, and metabolic syndrome. However, its role in acute pulmonary embolism (PE) is unknown. In this study, we aimed to investigate the relationship between GGT and early mortality in patients with acute PE. METHODS: A total of 127 consecutive patients with confirmed PE were evaluated. The optimal cutoff value of GGT to predict early mortality was measured as more than 55 IU/L with 94.4% sensitivity and 66.1% specificity. Patients with acute PE were categorized prospectively as having no increased (group I) or increased (group II) GGT based on a cutoff value. RESULTS: Of these 127 patients, 18 patients (14.2%) died during follow-up. Among these 18 patients, 1 (1.4%) patient was in group I, and 17 (30.9%) patients were in group II (P < .001). γ-Glutamyl transferase level on admission, presence of shock, heart rate, oxygen saturation, right ventricular dilatation/hypokinesia, main pulmonary artery involvement, troponin I, alanine aminotransferase, alkaline phosphatase, and creatinine levels were found to have prognostic significance in univariate analysis. In the multivariate Cox proportional hazards model, GGT level on admission (hazard ratio [HR], 1.015; P = .017), presence of shock (HR, 15.124; P = .005), age (HR, 1.107; P = .010), and heart rate (HR, 1.101; P = .032) remained associated with an increased risk of acute PE-related early mortality after the adjustment of other potential confounders. CONCLUSIONS: We have shown that a high GGT level is associated with worse hemodynamic parameters, and it seems that GGT helps risk stratification in patients with acute PE.

Levofloxacin-induced delirium: is it a dangerous drug in patients with renal dysfunction?

The central nervous system (CNS) toxicity of fluoroquinolones is well known but usually occurs benign. In the literature, there are a few number of severe CNS toxicity cases related to fluoroquinolones. Levofloxacin is a third-generation fluorinated quinolone antibiotic, is the active levo stereoisomer of ofloxacin, and has one of the most favorable adverse reaction profiles. We describe a case of delirium associated with levofloxacin in a 55-year-old man who was hospitalized in our medical clinic for pneumonia.

Evaluation of the Performance of Different Types of Fibrous Concretes Produced by Using Wollastonite.

Production of cement and aggregate used in cement-based composites causes many environmental and energy problems. Decreasing the usage of cement and aggregate is a crucial and currently relevant challenge to provide sustainability. Inert materials can also be used instead of cement and aggregates, similar to pozzolanic materials, and they have positive effects on cement-based composites. One of the inert materials used in cement-based composites is wollastonite (calcium metasilicate-CaSiO3), which has been investigated and attracted attention of many researchers. This article presents state-of-the-art research regarding fibrous concretes produced with wollastonite, such as mortars, conventional concrete, engineered cementitious composites, geopolymer concrete, self-compacting concrete, ultra-high-performance concrete and pavement concrete. The use of synthetic wollastonite, which is a novel issue, its high aspect ratio and allowing the use of waste material are also evaluated. Studies in the literature show that the use of wollastonite in different types of concrete improves performance properties, such as mechanical/durability properties, and provides environmental-economic efficiency. It has been proven by studies that wollastonite is a material with an inert structure, and, therefore, its behavior is similar to that of a fiber in cementitious composites due to its acicular particle structure.

Application of ECC as a Repair/Retrofit and Pavement/Bridge Deck Material for Sustainable Structures: A Review.

Concrete structures cannot efficiently perform their functions over time due to chemical and physical external effects. Thus, enhancing the relationship between repair and aged structures, and also improving the durability properties of concrete is crucial in terms of sustainability. However, high costs, negative environmental effects, and incompatibility problems occur in repair/retrofit applications. Furthermore, three-quarters of the failures in the repaired/retrofitted structures are caused by a lack of repair durability. The need for repair in pavement/bridge decks is also frequently encountered, and early-age performance problems with repair materials cause pavement/bridge decks to be unavailable for certain periods of time. Engineered Cementitious Composite (ECC) can be effectively used as repair/retrofit and pavement/bridge deck material. It also has a minimal need for repair/retrofit thanks to its high durability properties. This article presents state-of-the-art research regarding the application of ECC as a repair/retrofit and pavement/bridge deck material. Studies in the literature show that the repair/retrofit properties of ECC outperform conventional concrete and steel fiber-reinforced concrete. ECC can be a solution to high early strength and drying shrinkage problems frequently encountered in the use of repair materials. It could also be used for different repair applications such as cast, sprayed, and trenchless rehabilitation. Moreover, ECC might fulfill specific requirements for pavement, pavement overlay, tunnel pavement, airfield pavement, and bridge deck. These superior performances are attributed to ECC's kink-crack trapping mechanism, uniquely large inelastic strain capacity, strain hardening, high tensile strain capacity, and multiple microcracking and ductile behaviors, especially bonding behavior and self-healing.

The amoebicidal activity of three substances derived from benzothiazole on Acanthamoeba castellanii cysts and trophozoites and its cytotoxic potentials.

Acanthamoeba species are free-living amoebae isolated from many ecological areas such as swimming pools, dams, lakes, soil, and air filters. These amoebae are usually causing granulomatous amebic encephalitis and amebic keratitis in immunosuppressive individuals. In this study, the reproductive potential and morphological changes determined of Acanthamoeba castellanii trophozoite and cyst forms exposed to three different active substances derived from benzothiazole. Furthermore, the cytotoxic potential of these active substances determined by XTT analysis. In the study, axenic cultures prepared for Acanthamoeba castellanii cyst and trophozoite forms and parasite exposed to different concentrations of active substances. Cell counts of parasite cultures were performed at the 30 minutes, 1st, 6th, 12th, 24th, and 48th hour periods. As a result of the study, the reproductive potential suppressive effects of all three substances on Acanthamoeba castellanii trophozoites and cysts were determined. The most effective of these substances was 2-Amino-6(trifluoromethoxy)-benzothiazole. In the first three concentrations of this substance (0.1%, 0.05%, 0.025%), no determined trophozoite and cysts at the end of twenty four. Due to its strong ameobicidal effect, it is thought that 2-Amino-6(trifluoromethoxy)-benzothiazole may be a new therapeutic agent in diseases caused by acanthamoeba parasites by supporting this study with animal experiments.

Development of malignant ventricular arrhythmias in a young male with WPW pattern.

In Wolff-Parkinson-White Syndrome (WPW), presence of accessory pathways causes various tachyarrhythmias that lead to different symptoms and clinical conditions in patients. Atrial fibrillation is observed in about 20-30% of this group of patients. Life threatening malignant ventricular arrhythmias and sudden cardiac deaths are observed in patients having rapid conduction in accessory pathways and short antegrade refractory periods (<250 msn). We present a WPW syndrome case that presented to the emergency service with narrow QRS tachycardia and later developed malignant ventricular arrhythmia.

Wet Cupping Therapy Improves the Parameters of Ventricular Repolarization.

BACKGROUND: Cupping therapy (CT) is an ancient medical treatment since antiquity and is used for the treatment of such various disease states as contagious diseases, chronic or acute inflammatory disease, and autoimmune disorders. Ventricular repolarization is represented by QT and corrected-QT (QTc) intervals from surface electrocardiography. OBJECTIVES: As novel repolarization parameters, Tpeak-toTend (Tp-Te) interval, and Tp-Te/QT and Tp-Te/QTc ratios are suggested to correlate better with ventricular arrhythmia risk in various clinical conditions than sole QT and QTc intervals. In this study, we aimed to determine whether these parameters changed significantly after CT in healthy individuals. METHODS: One hundred and twenty participants (57 women and 63 men; mean age: 49.0 ± 13.0 years) participated in this study. ECGs strips were recorded 1 hour before and 1 hour after CT from each participant, and relevant ECG parameters were compared. RESULTS: Tp-Te interval [69.51 ± 11.54 msec vs 63.15 ± 10.89 msec, p = 0.001], Tp-Te/QT ratio [0.191 ± 0.030 vs 0.174 ± 0.031, p = 0.002] and Tp-Te/QTc ratio [0.175 ± 0.030 vs 0.159 ± 0.026, p = 0.001] were found to be significantly decreased 1 hour after the procedure compared with the pre-procedure values. However, no statistically significant change was observed in mean heart rate, QT and QTc intervals, QT/QRS and cQT/QRS, and frontal QRS/T angle after the procedure compared with the same parameters before the procedure (p > 0.05). CONCLUSIONS: In accordance with the results of our study, it is plausible to conclude that CT may exert cardioprotective effect. However, larger scale prospective studies are needed to support our findings.
