RESUMO
OBJECTIVE: Workers describe many physical and mental symptoms when working in radiation areas. This study aimed to assess these symptoms in radiation workers using the Beck Anxiety Inventory (BAI). METHODS: A total of 42 radiation workers (22 males and 20 females, mean age 34±7 years) and 47 control subjects (22 males and 27 females, mean age 31± 8 years) who work in non-radiation areas in the hospital were included in the study. All participants anonymously filled out the Beck Anxiety Inventory (BAI) questionnaire. RESULTS: The demographic data of workers were not significantly different between groups. In the BAI, the dizzy or lightheaded (p =0.01), terrified (p= 0.01), unsteady (p=0.02), heart-pounding and racing (p=0.02) items were significantly higher in the radiation-exposed group compared to the control group. |The BAI score was also significantly higher in the radiation-exposed group (11.1±6.8 vs. 8.7±3.8, p =0.04). CONCLUSION: These results suggest the possibility that radiation may play a role in the psychometric properties of workers. The effects of radiation on the health of employees need to be further investigated and understood.

RESUMO OBJETIVO: Ao trabalhar em áreas de radiação, trabalhadores descrevem muitos sintomas físicos e mentais. Este estudo teve como objetivo avaliar esses sintomas em trabalhadores expostos à radiação utilizando a Escala de Ansiedade de Beck (BAI - Beck Anxiety Inventory). MÉTODOS: Um total de 42 trabalhadores expostos à radiação (22 homens e 20 mulheres, com idade média de 34±7 anos) e 47 controles (22 do sexo masculino e 27 do sexo feminino, com idade média de 31±8 anos) que trabalham em áreas do hospital sem radiação foram incluídos no estudo. Todos os participantes responderam anonimamente ao questionário da BAI. RESULTADOS: Os dados demográficos dos trabalhadores dos dois grupos não apresentaram diferenças significativas. Na BAI, os itens de tonturas ou vertigens (p =0,01), medo (p= 0,01), instabilidade (p=0,02) e batimento cardíaco mais forte e acelerado (p=0,02) foram significativamente mais elevados no grupo exposto à radiação em comparação ao grupo de controle. A pontuação da BAI também foi significativamente maior no grupo exposto à radiação (11,1 ± 6,8 versus 8,7 ± 3,8, p = 0,04). CONCLUSÃO: Esses resultados sugerem a possibilidade de que a radiação pode desempenhar um papel importante nas propriedades psicométricas dos trabalhadores. Os efeitos da radiação na saúde dos funcionários precisam ser mais bem investigados e compreendidos.

OBJECTIVE: Inflammation has been suggested as a potential mechanism in the pathogenesis of arrhythmia. Hemogram parameters such as monocyte count to high-density lipoprotein cholesterol ratio (MHR), neutrophil/lymphocyte ratio (NLR), and monocyte/lymphocyte ratio (MLR) have been considered to be markers of inflammation and new cardiovascular risk predictors. This retrospective study aimed to investigate the relationship between MHR, NLR, and MLR in patients with paroxysmal supraventricular tachycardia (PSVT). METHODS: A retrospective study conducted at a university hospital in Bolu, Turkey, between 2017 and 2019. Our study included 196 patients who underwent electrophysiological study (EPS) due to palpitation or documented PSVT on electrocardiography (ECG). Patients having documented atrioventricular nodal re-entrant tachycardia (AVNRT) on ECG or inducible AVNRT on EPS were included in the PSVT group (n=130), and patients with palpitation but without inducible arrhythmia on EPS (n=66) were included in the control group. Routine biochemical and hemogram tests were performed before the EPS procedure. RESULTS: When hemogram parameters were compared, there was no statistically significant difference in MHR values [0.010 (0.001-0.030) vs 0.010 (0.001-0.020) p =0.67]. Additionally, both NLR [2.21(0.74-11.36) vs 1.98(0.72-24.87) p=0.13] and MLR [0.25 (0.03-1.05) vs 0.24(0.07-1.39) p=0.41] were not statistically significant between the two groups. CONCLUSION: There is no significant difference in PSVT patients regarding hemogram parameters including white blood cell subtypes, MLR, NLR, and MHR. Therefore the evaluation of hemogram parameters may not be clinically relevant for PSVT patients.

RESUMO OBJETIVO: A inflamação tem sido sugerida como um mecanismo potencial na patogênese da arritmia. Parâmetros do hemograma, como contagem de monócitos e razão de colesterol lipoproteína de alta densidade (MHP), proporção de neutrófilos / linfócitos (NLP) e proporção de monócitos / linfócitos (MLR), foram considerados marcadores de inflamação e novos preditores de risco cardiovascular. Este estudo retrospectivo teve como objetivo investigar a relação entre MHP, NLP e MLP em pacientes com taquicardia paroxística supraventricular (PSVT). MÉTODOS: Estudo retrospectivo realizado em um hospital universitário em Bolu, Turquia, entre 2017 e 2019. Nosso estudo incluiu 196 pacientes submetidos a estudo eletrofisiológico (EPS) devido a palpitações ou PSVT documentada na eletrocardiografia (ECG). Os pacientes com taquicardia nodal atrioventricular reentrante (AVNRT) no ECG ou AVNRT indutível no EPS foram incluídos no grupo PSVT (n = 130) e os pacientes com palpitações sem arritmia induzível no EPS (n = 66) foram incluídos no grupo controle. Testes bioquímicos e de hemograma de rotina foram realizados antes do procedimento de EPS. RESULTADOS: Quando os parâmetros do hemograma foram comparados, não houve diferença estatisticamente significante nos valores de MHP (0,010 (0,001-0,030) vs 0,010 (0,001-0,020) p = 0,67). Além disso, tanto o NLP (2,21 (0,74-11,36) vs 1,98 (0,72-24,87) p = 0,13) quanto o MLP (0,25 (0,03-1,05) vs 0,24 (0,07-1,39) p = 0,41) não foram estatisticamente significantes entre os dois grupos. CONCLUSÃO: Não há diferença significativa nos pacientes com PSVT em relação aos parâmetros do hemograma, incluindo os subtipos de glóbulos brancos, MHP, NLP e MHP. Portanto, a avaliação dos parâmetros do hemograma pode não ser clinicamente relevante para pacientes com PSVT.

OBJECTIVE: To investigate the effects of lidocaine oropharyngeal spray applied before endotracheal intubation on hemodynamic responses and electrocardiographic parameters in patients undergoing coronary artery bypass grafting. METHODS: A total of 60 patients who underwent coronary artery bypass grafting surgery were included in this prospective randomized controlled study. Patients were randomly divided into two groups, the topical lidocaine group (administration of 10% lidocaine oropharyngeal spray, five minutes before laryngoscopy and endotracheal intubation) and the control group. Both groups were compared with each other in terms of main hemodynamic parameters including mean arterial pressure and heart rate, as well as P and QT wave dispersion durations, before and after endotracheal intubation. RESULTS: The groups were similar in terms of age, gender, and other demographics and basic clinical characteristics. There was a statistically significant difference between the groups in terms of QT dispersion durations after laryngoscopy and endotracheal intubation. The increase in QT dispersion duration was not statistically significant in the topical lidocaine group, whereas the increase in QT dispersion duration was statistically significant in the control group. When the groups were compared in terms of P wave dispersion durations, there were significant decreases in both groups, but there was no significant difference between the groups. CONCLUSION: Our study revealed that the topical lidocaine administration before endotracheal intubation prevented increase of QT dispersion duration in patients undergoing coronary artery bypass grafting. TRIAL REGISTRATION: NCT03304431.

OBJECTIVE: To investigate the effects of preoperative anxiety relieving on electrophysiological changes in patients undergoing off-pump coronary artery bypass surgery. METHODS: A total of 61 patients at ASA III risk group in the age range of 18-65 years were enrolled in the present study. Patients were randomly divided into two groups. Group S (Sedation group) was administered 0.04 mg/kg lorazepam per os (PO) twice before the operation. Group C (control group) was not administered with any anxiolytic premedication. State Trait Anxiety Inventory (STAI-I) and Beck Anxiety Inventory (BAI) were used to evaluate the level of anxiety. Electrocardiography (ECG), pulse oximeter and standard monitoring were performed for each patient. QT and P dispersions in each derivation of all ECGs were calculated. RESULTS: Preoperative STAI-I scores were significantly lower in sedation group compared to the controls. Mean values of QT dispersion measured before induction, at the 1st minute of induction, 30th second of intubation and 4th minute of intubation in sedation group were significantly reduced compared to controls (P=0.024; P=0.027; P=0.001; P=0.033, respectively). The mean values of P dispersion measured before induction, at the 3rd minute of induction, 30th second of intubation and 4th minute of intubation in sedation group were significantly reduced compared to controls (P=0.001; P=0.020; P=0.023; P=0.005, respectively). CONCLUSION: Elevated anxiety levels in patients undergoing coronary bypass surgery have a negative effect through prolonged QT and P-wave dispersion times. Anxiolytic treatment before surgery may be useful to prevent ventricular and atrial arrhythmias and associated complications through decreasing the QT and P-wave dispersion duration.

BACKGROUND: Coronary artery fistula (CAF) is an abnormal connection that links a coronary artery to a cardiac chamber or another major blood vessel. Several studies have shown the association between mean platelet volume (MPV) and cardiovascular diseases. In the literature, there is no previous study about the association between hematologic parameters and congenital CAF. For this reason, we aimed to investigate the association of MPV with CAF. METHODS: 70 patients with normal coronary arteries and 50 with coronary artery fistulas were included. Routine blood and biochemical parameters were measured before the arteriography. Differences between groups for continuous variables were analyzed with t- test or Mann-Whitney test. P values < 0.05 were considered significant. Regression analysis was used to find independent predictors of CAF. RESULTS: Baseline patient demographics, including age and clinical risk factors, were similar between the groups. Compared to the control group, median (IQR) High-density lipoprotein cholesterol (HDL) levels were significantly higher (p=0.04) and MPV levels were significantly lower in the CAF group (8.84 ± 1.71fL vs. 10.43 ± 1.34, p < 0.001). In the multivariate analysis, only MPV was a significant predictor of CAF (p < 0.001, 95% CI for OR: 0.438 (0.306-0.629). A negative correlation was found between MPV and fistulae in Pearson's correlation test (r: -0.454, p < 0.001). An MPV level of < 9,6 fL showed sensitivity, specificity, positive predictive value and negative predictive value of 80%, 68%, 71% and 78% respectively (AUC = 0.766, 95% CI, 0.678-0.854) for the prediction of CAF. CONCLUSION: The present study suggests that MPV may decrease in patients with CAF.

Resumo Fundamento: A fístula da artéria coronária (FAC) é uma conexão anormal que liga a artéria coronária a uma câmara cardíaca ou outro importante vaso sanguíneo. Vários estudos mostraram a associação entre o volume plaquetário médio (VPM) e as doenças cardiovasculares. Na literatura, não há estudo prévio sobre a associação entre os parâmetros hematológicos e a FAC congênita. Por essa razão, nosso objetivo foi investigar a relação do VPM com a FAC. Métodos: Foram incluídos 70 pacientes com artérias coronárias normais e 50 com fístulas de artérias coronárias. Os parâmetros sanguíneos e bioquímicos de rotina foram medidos antes da arteriografia. As diferenças entre os grupos para as variáveis contínuas foram analisadas com o teste t ou teste de Mann-Whitney. Valores de p < 0,05 foram considerados significativos. A análise de regressão foi utilizada para encontrar preditores independentes de FAC. Resultados: Os dados demográficos basais dos pacientes, incluindo idade e fatores de risco clínicos, foram semelhantes entre os grupos. Comparados à mediana do grupo controle (IIQ), os níveis de HDL-colesterol foram significativamente mais altos (p = 0,04) e os níveis de VPM foram significativamente mais baixos no grupo FAC (8,84 ± 1,71fL vs. 10,43 ± 1,34, p < 0,001). Na análise multivariada, apenas o VPM foi um preditor significativo de FAC (p<0,001, IC 95% para OR: 0,438 (0,306-0,629)). Foi encontrada uma correlação negativa entre o VPM e fístulas no teste de correlação de Pearson (r: -0,454, p < 0,001). Um nível de VPM < 9,6 fL apresentou sensibilidade, especificidade, valor preditivo positivo e valor preditivo negativo de 80%, 68%, 71% e 78%, respectivamente (AUC = 0,766, IC 95%, 0,678-0,854) para a previsão de FAC. Conclusão: O presente estudo sugere que o VPM pode diminuir no paciente com FAC.
