Effect of chelation therapy on arrhythmogenic and basal ECG parameters of lead exposed workers

Lead exposure has etiological role on cardiovascular system diseases as hypertension, ath erosclerosis, stroke, and arrhythmic events. In this study, we aimed to compare the basal and arrhythmogenic ECG parameters of lead exposed workers before and after chelation therapy and to evaluate the effect of acute change of blood lead levels on ECG. Fourty con secutive occupationally lead exposed workers were enrolled, demographic, blood, echocar diographic, and electrocardiographic data’s were analyzed before and after chelation therapy. Pmax, P min, P Wave Dispersion, and QT Dispersion values which are arrhythmia predictors were significantly lower after chelation therapy compared to values before chela tion therapy. Lead exposed workers are under the risk of ventricular and atrial arrythmias and chelation treatment has a positive effect on these parameters

Does the Change in the Indications of Endoscopic Sinonasal Surgery Continue? Data between 1994-2018

Objective: Endoscopic sinonasal surgery (ESS) has changing over the years in parallel with the developments in endoscopy devices, video-imaging techniques, and surgical instruments. In the present study we investigated whether the indications of patients who underwent surgery over a period of 25 years have accommodated to these changes.Methods: We retrospectively evaluated 1173 patients who underwent surgery in our clinic from 1994 through 2007, and 954 patients who underwent surgery from 2008 through 2018. The patients were divided into three groups as follows: chronic rhinosinusitis with polyps (CRSwNP), chronic rhinosinusitis without polyps (CRSsNP), and others. The changes in the indications during the first 14 years and the following 11 years were compared, and the results were statistically evaluated.Results: A significant decrease was observed in the number of patients who underwent surgery following the diagnosis of CRSsNP (p<0.001). In addition, a statistically significant increase was found in CRSwNP (p<0.001) and other (p<0.001) indications.Conclusion: When ESS indications identified in our clinic were reviewed, it was observed that the increasing trend in CRSwNP rate in the first 14 years continued, there was a significant increase in non-CRS indications in the last 11 years, and there has been an increase in patients with fungal sinusitis, especially in this group

Variación fenotípica en poblaciones de veza (Vicia sativa ssp.) del centro de Turquía, sembradas en otoño y primavera

In central Turkey, common vetch (Vicia sativa ssp. sativa) is traditionally grown in spring. Frequent droughts cause crop failures. Autumn sowing can give higher yields, but then winter plant death is a major problem. The objective of this research was to explore and quantify variation available in V. sativa ssp. germplasm for winter hardiness, yield and adaptability. Eleven plant characters were evaluated in 164 vetch populations in autumn and spring sowings over two years, and their inter-relationships were analyzed. Mean winter death was 27% and was greater in the second, colder year, though the magnitude of the coefficient-of-variation was similar in both years (27 and 28%). Autumn-sown plants produced more standing biomass (17%) than spring-sown plants. Winter death was strongly related to other characters, particularly in the colder year. Principle component analysis proved to be efficient at simplifying the results by classifying the eleven variables into three main groups on the basis of seed size, maturity and winter hardiness. There is wide, exploitable phenotypic variation, and enhanced adaptation for autumn sowing could be achieved by selecting for large seeds and early maturity combined with reasonable winter survival.La veza (Vicia sativa ssp. sativa) crece tradicionalmente en el centro de Turquía y las cosechas sufren pérdidas importantes en las frecuentes temporadas de sequía en primavera. La siembra en el otoño puede conducir a rendimientos más altos, pero las plantas pueden sufrir una mortandad elevada en el invierno, lo que representa un problema mayor. El objetivo de nuestra investigación fue explorar y cuantificar la variación para el vigor, el rendimiento y la adaptabilidad en una colección de germoplasma de V. sativa ssp. Se analizaron once caracteres vegetativos y sus inter-relaciones en 164 poblaciones de haba en siembras de otoño y primavera durante dos años. La mortalidad media en invierno fue un 27% superior en el segundo año, aunque la magnitud del coeficiente de variación fue similar en ambos años (27% y 28%). Las plantas sembradas en otoño produjeron más biomasa (17%) que las de primavera. La mortalidad registrada en invierno estuvo fuertemente relacionada con otros caracteres, particularmente con el índice de heladas anual. El análisis de componentes principales demostró su eficiencia para la simplificación y clasificación de las once variables en tres grupos principales sobre la base del tamaño de la muestra, madurez y resistencia al frío. Existe una amplia variación aprovechable y se demuestra la posibilidad de incrementar la adaptación en la siembra de otoño, con una razonable supervivencia en invierno, mediante la selección de plantas con semillas de mayor tamaño y madurez temprana

Relationship of brain natriuretic peptide with metabolic syndrome parameters: An observational study [Beyin natriüretik peptidin metabolik sendrom parametreleri ile ilişkisi: Gözlemsel bir çalışma]

PubMedID: 22037102Objective: Metabolic syndrome (MS) was independently associated with increased risk of incident heart failure and coronary artery disease. In this study, we sought to identify whether there is an association between metabolic syndrome components and left ventricular diastolic functions and brain natriuretic peptide (BNP) levels. Methods: This study is a cross-sectional, observational study. Two hundred consecutive patients with MS were selected to form the study population. Echocardiographic parameters and BNP were determined. Mann-Whitney U test and Kruskal-Wallis test were used to compare BNP levels in categorical variables. Spearman rank correlation analysis was used to investigate the correlation between BNP level and other numerical variables. Linear regression analysis was used to find the variables affecting the BNP level. Results: BNP level was higher in females than males [11.14 (0.12-87) vs 7.49 (0.01-99) pg/dl, p=0.04]. None of the MS parameters affects the BNP level in MS patients. MS criteria number that the patient had was not related to BNP level. Sixty seven percent of patients had left ventricular (LV) diastolic dysfunction. BNP was independent from LV diastolic function. Multiple linear regression analysis demonstrated that having diabetes mellitus increases BNP level by 7.73 unit (ß=7.73, 95% CI - 2.321 - 13.149, p=0.006). Conclusion: None of the MS parameters affects the BNP level in MS patients. Diastolic dysfunction existence did not affect the BNP level of MS patients. There is an association between diabetes mellitus and BNP, independent of left ventricle diastolic functions. © 2011 by AVES Yayincilik Ltd

Geriatric patient admissions to the emergency service

Objective: In this study, we aimed to analyze the demographic features of patients older than 65 years admitted to the emergency department. Material and Methods: All patients who were over 65 years old and admitted to a tertiary care emergency department were included in this retrospective study. Information, including admission dates (month, season), age, sex, admission type, diagnosis, duration of hospitalization, and outcome in the emergency department of the patients, was evaluated. The obtained data were analyzed with student t-test and chi-square test by using SPSS 17.0 software. Results: Of 238,222 patients admitted to the emergency department, 8793 (3.6%) were over 65 years old; 58% of the patients were female and 42% were male. The rate of chronic obstructive pulmonary disease (COPD) among respiratory problems in males and the rate of hypertension among cardiac problems in females were found to be significantly high. The highest admission rate was in the autumn months (32.6%). The most common reason for admission to the emergency department was cardiac problems (21.7%). This was followed by neurological problems, trauma, respiratory system problems, and urinary tract infections, respectively. The highest mortality rate was 45% in the general intensive care unit. The most frequent cause for mortality was cardiac problems. Conclusion: Cardiac problems were the most common cause of admissions to the emergency department, hospitalization, and mortality in geriatric patients. Future studies for determining the admission rate and most frequently observed illnesses of geriatric patients might be helpful in developing special care areas and special scanning tests for geriatric patients.
