Oxidatively-induced DNA base damage and base excision repair abnormalities in siblings of individuals with bipolar disorder DNA damage and repair in bipolar disorder.

Previous evidence suggests elevated levels of oxidatively-induced DNA damage, particularly 8-hydroxy-2'-deoxyguanosine (8-OH-dG), and abnormalities in the repair of 8-OH-dG by the base excision repair (BER) in bipolar disorder (BD). However, the genetic disposition of these abnormalities remains unknown. In this study, we aimed to investigate the levels of oxidatively-induced DNA damage and BER mechanisms in individuals with BD and their siblings, as compared to healthy controls (HCs). 46 individuals with BD, 41 siblings of individuals with BD, and 51 HCs were included in the study. Liquid chromatography-tandem mass spectrometry was employed to evaluate the levels of 8-OH-dG in urine, which were then normalized based on urine creatinine levels. The real-time-polymerase chain reaction was used to measure the expression levels of 8-oxoguanine DNA glycosylase 1 (OGG1), apurinic/apyrimidinic endonuclease 1 (APE1), poly ADP-ribose polymerase 1 (PARP1), and DNA polymerase beta (POLß). The levels of 8-OH-dG were found to be elevated in both individuals with BD and their siblings when compared to the HCs. The OGG1 and APE1 expressions were downregulated, while POLß expressions were upregulated in both the patient and sibling groups compared to the HCs. Age, smoking status, and the number of depressive episodes had an impact on APE1 expression levels in the patient group while body mass index, smoking status, and past psychiatric history had an impact on 8-OH-dG levels in siblings. Both individuals with BD and unaffected siblings presented similar abnormalities regarding oxidatively-induced DNA damage and BER, suggesting a link between abnormalities in DNA damage/BER mechanisms and familial susceptibility to BD. Our findings suggest that targeting the oxidatively-induced DNA damage and BER pathway could offer promising therapeutic strategies for reducing the risk of age-related diseases and comorbidities in individuals with a genetic predisposition to BD.

Comparison of patient positions without traction table for proximal femoral nailing: Supine, semilithotomy and lateral decubitus positions.

BACKGROUND: Femur intertrochanteric fractures are performed commonly in a supine position with a traction table. There is a challenge in obtaining traction tables, especially in low- and middle-income countries. However, there is still a debate on which position should be preferred if the traction table cannot be obtained. METHODS: A total of 123 patients who were treated for femur intertrochanteric fracture (AO/OTA A1 or A2) using cephalomedullary nail (CN) were retrospectively analyzed. All three positions without traction table (supine:25 patients, semilithotomy:36 patients and lateral decubitus:62 patients) were compared according to preparation time, surgical time, Tip-Apex distance (TAD), zones of lag screw placement, collodiaphyseal angle (CDA), CDA difference (∆ CDA), postoperative posterior sag, medial cortical support and Baumgardner reduction quality criteria. RESULTS: The preparation time was longer in the semilithotomy group, and surgery time was longer in the supine position group. There was no difference according to total time, surgical time, TAD, CDA difference (∆ CDA), postoperative posterior sag, medial cortical support and Baumgardner reduction quality criteria. Target lag screw placement is superior in supine and semilithotomy group than lateral decubitus. CONCLUSION: This study concluded that there was a difference in preparation time, surgery time and optimal lag screw placement in the lateral plane between groups. The surgeon may prefer all three methods according to patient benefit and surgeon familiarity.

The relationship between prognostic nutritional index and long-term mortality in patients undergoing emergency coronary artery bypass graft surgery for acute-ST elevation myocardial infarction.

BACKGROUND: Malnutrition and the prognosis of coronary artery disease (CAD) are shown to be correlated. The significance of nutritional status has been evaluated in patients with ST elevation myocardial infarction (STEMI), stable CAD, and elective coronary artery bypass graft (CABG) surgery. However, the prognostic impact of poor nutritional status on STEMI patients who underwent emergent CABG is not known. In this study, we aimed to investigate the relationship between nutritional status assessed by the prognostic nutritional index (PNI) and long-term mortality in STEMI patients who underwent emergent CABG. To the best of our knowledge, our study is the first one to evaluate the PNI effect on this specific population. METHODS: 131 consecutive patients with STEMI who did not qualify for primary percutaneous coronary intervention and required emergent CABG between 2013 and 2018 were included in our study. The study population was divided into two groups: survivors and non-survivors. The PNI was calculated as 10 × serum albumin (g/dL) + 0.005 × total lymphocyte count (per mm3) for both groups, using the preoperative data. The optimal cut-off value was obtained by receiver operating characteristic (ROC) analysis. According to the cut-off value, we investigated the relationship between PNI and long-term mortality. RESULTS: The mean age of the study population was 57.0±10.6. During the median 92.7 (70.0-105.3)-month follow-up, 32 of the 131 patients (24.4%) died. Regression analysis showed a significant association between glucose levels (hazard ratio (HR), 1.007; 95% confidence interval (CI), 1.002-1.012; p=0.011) and PNI (HR, 0.850; 95% CI, 0.787-0.917; p<0.001) and long-term mortality. Accord-ing to the ROC analysis, the cut-off value for PNI to predict all-cause mortality was found to be 44.9, with a sensitivity of 81.3% and a specificity of 89.9%. In addition, age, ejection fraction, glomerular filtration rate, Killip classification, and left anterior descending-left internal mammary artery graft use are significantly associated with long-term all-cause mortality in STEMI patients undergoing emergency CABG. CONCLUSION: The PNI was significantly associated with long-term mortality in patients with STEMI who underwent emergent CABG. PNI can be used to improve the accuracy of the risk assessment of STEMI patients undergoing emergent CABG.

Downregulation of TRPM7, TRPM8, and TRPV1 channels modulate apoptotic parameters and neurodegenerative markers: Focus on neuronal differentiation and Parkinson's disease model.

The transient receptor potential channel (TRP) channels are expressed in neuronal tissues and involved in neurological diseases such as pain, epilepsy, neuronal apoptosis, and neurodegenerative diseases. Formerly, we have investigated how neuronal differentiation changes TRP channels expression profile and how Parkinson's disease model is related with this expression levels. We have found that transient receptor potential channel melastatin subtype 7 (TRPM7), transient receptor potential channel melastatin subtype 8 and transient receptor potential channel vanilloid subtype 1 (TRPV1) channels have pivotal effects on differentiation and 1-Methyl-4-phenylpyridinium (MPP+ )-induced Parkinson's disease model in SH-SY5Y cells. In this study, we have investigated that downregulation of the TRP channels to evaluate how differentiation status changes to Parkinson's disease pathological hallmarks. We have also performed to other analyses to elucidate these TRP channels' function in MPP+ -induced neurotoxicity related apoptosis, cell viability, caspase 3 and 9 enzyme activities, intracellular reactive oxygen species production, mitochondrial depolarization levels, Ca2+ signaling, Alpha-synuclein and Dopamine levels, mono amino oxidase A and B enzymatic activities, both in differentiated and undifferentiated neuronal cells. Herein we have concluded that especially TRPM7 and TRPV1 channels have distinct role in Parkinson's disease pathology via their activity changings in pathological state, and downregulation of these channels or specific antagonists can be useful for the possible treatment strategy for Parkinson's disease and related markers.

A Simple Predictor for Long-Term Mortality After Percutaneous Iliac Artery Intervention: Systemic Immune Inflammatory Index.

BACKGROUND: Peripheral arterial disease is a common disease all over the world. Medical treatment, percutaneous invasive treatment, and operation are the considerable options. Percutaneous treatment is a valid option with a higher patency rate. Systemic immune-inflammatory index (SII) is a formula which is calculated as neutrophil count to platelet count divided into lymphocyte count. This formula demonstrates the active inflammatory state. In our study, we aimed to demonstrate the relationship with SII and the mortality, major cardiovascular events, and success rates of percutaneous treatment of iliac artery disease. METHODS: A total of 600 patients underwent percutaneous intervention due to iliac artery disease were enrolled. The primary end point was mortality and the secondary end points were in-hospital thrombosis, restenosis, residual stenosis, and postintervention complications. The best cut-off value of SII to predict mortality was determined and the patients were divided into 2 groups, as those with higher SII values (1,073.782 <) and as those with lower SII values (1,073.782 >). Each group was evaluated in terms of clinical, laboratory, and technical aspects. RESULTS: After exclusion criteria were applied, 417 patients were enrolled into the study. Patients with high SII values had higher rates of in-hospital thrombosis [0 (0%); 3 (2.2%), P = 0.037] and mortality [38 (13.7%); 46 (33.1%), P < 0.001]. In multivariate logistic regression analysis, chronic kidney disease [odds ratio: 4.104, 95 0.5 confidence interval: 2.250-7.487, P < 0.001] and SII [odds ratio: 3.346, 95 0.5 confidence interval: 1.982-5.649, P < 0.001] were found to be independent risk factors for mortality. CONCLUSIONS: SII is a relatively new, simple, and effective mortality risk predictor in patients with iliac artery disease who underwent percutaneous intervention. To the best of our knowledge, our study is the first study which uses SII to predict mortality in such patient group.

The relationship between sarcopenia-related measurements and osteoporosis: The SARCOP study.

As muscle and bone are closely-related, we have explored the association between sarcopenia-related measurements and bone mineral density (BMD) (and osteoporosis) in postmenopausal women. Grip strength, anterior thigh muscle thickness and chair stand test were found to be related with BMD. Additionally, grip strength < 22 kg increased the odds ratio of osteoporosis 1.6 times. INTRODUCTION: As muscle and bone are two closely related tissues, we aimed to investigate the association between sarcopenia-related measurements (i.e., sonographic anterior thigh muscle thickness, grip strength, chair stand test (CST), gait speed) and clinical factors, lumbar/femoral BMD, and the presence of osteoporosis (OP) in postmenopausal women. METHODS: Community dwelling postmenopausal women from two physical and rehabilitation medicine outpatient clinics were consecutively included in this cross-sectional study. Demographic data, age, weight, height, education/exercise status, smoking, and comorbidities were registered. BMD measurements were performed from lumbar vertebrae (L1-4) and femoral neck using dual energy X-ray absorptiometry (DXA). A T-score of ≤ -2.5 SD in the lumbar vertebrae (L1-L4) and/or femoral neck was accepted as OP. Anterior thigh muscle thickness (MT) at the midthigh level was measured sonographically using a linear probe. Grip strength was measured from the dominant side. Physical performance was assessed by CST and gait speed. RESULTS: Among 546 postmenopausal women, 222 (40.7%) had OP. Among sarcopenia-related parameters, grip strength and anterior thigh MT were positively associated with lumbar vertebral BMD. CST performance was positively associated with femoral neck BMD. After adjusting for confounding factors, low grip strength (< 22 kg) increased 1.6 times the risk of OP. CONCLUSION: Loss of muscle mass/function (i.e., sarcopenia) can coexist with loss of trabecular and cortical bone. To this end, grip strength and anterior thigh MT seem to be associated with the lumbar vertebral BMD, while CST is associated with the femoral neck BMD. Lastly, low grip strength might have an association with postmenopausal OP.

The prognostic value of C-reactive protein to albumin ratio in patients undergoing transcatheter aortic valve implantation.

BACKGROUND: Transcatheter aortic valve implantation (TAVI) is a less invasive and safe therapeutic alternative in patients who are at very high surgical risk or in whom there are contraindications to open surgery. On the other hand, allocating transcatheter therapy to the adequate candidates and identifying a reliable and validated risk stratification tool for mortality prediction is still lacking. The C-reactive (CRP) to albumin ratio (CAR) is a novel inflammation-based prognostic tool and it is strongly associated with inflammation severity and mortality. In this study, we aimed to elucidate the predictive significance of CAR for mortality in patients who underwent TAVI. METHODS: The records of 321 consecutive patients who underwent TAVI due to symptomatic aortic stenosis between 1 January 2015 and 31 December 2020 were analysed. Patients were divided into two groups based on the CAR values. For each group, all-cause, cardiovascular, and non-cardiovascular mortality occurring >72 h after the index procedure and at maximum follow-up was documented. RESULTS: The mean follow-up time was 40 (22-63) months. A total of 180 (56.1%) patients died during long-term follow-up. According to our study, median CAR values were significantly higher among patients who died during follow-ups compared to survivors [1.13 (0.69-2.21) vs 3.56 (1.53-10.00), p < 0.001]. CONCLUSION: Our data showed that CAR is an independent predictor of long-term mortality in patients undergoing TAVI due to symptomatic aortic stenosis.

A Novel Marker Indicating Restenosis in Superficial Femoral Artery: C Reactive Protein to Albumin Ratio.

BACKGROUND: In this study, we aimed to investigate the prognostic value of C-reactive protein (CRP) to albumin ratio (CAR) for predicting restenosis in superficial femoral artery (SFA) lesions and its association with subsequent clinical outcomes in patients undergoing endovascular intervention. METHODS: The records of 685 consecutive patients who underwent endovascular intervention due to symptomatic peripheral artery disease were analyzed. Patients were divided into 2 groups, based on the CAR values. For each group, technical aspects of procedures and subsequent clinical outcomes were analyzed. RESULTS: According to our study, patients with high CAR values had higher rates of restenosis (30.2% vs. 10.3%, P < 0.05) and mortality (31.3% vs. 12.9%, P < 0.05). The rate of lower extremity amputations was also significantly higher in patients with high CAR values compared to those with low CAR values (9.1% vs. 3%, P < 0.05). With respect to Receiver operating characteristic ROC curves of inflammatory markers, the area under the curve (AUC) value of CAR was statistically significant (AUC: 0.659; 95% confidence interval CI: 0.611-0.706; P < 0.01). CONCLUSIONS: Our data showed that CAR is an independent predictor of restenosis and poor clinical outcomes in patients undergoing endovascular intervention.

Fragmented QRS complex may predict long-term mortality after isolated surgical aortic valve replacement in patients with severe aortic stenosis.

OBJECTIVES: Fragmented QRS (fQRS), related to myocardial fibrosis, is an important prognostic marker of cardiovascular events and mortality. Aortic stenosis (AS), the most frequent valvular heart disease in developed countries, causes myocardial fibrosis due to ventricular pressure overload. The current study aimed to investigate whether fQRS is associated with long-term mortality after isolated surgical aortic valve replacement (SAVR) in patients with severe AS. METHODS: A total of 289 patients who underwent SAVR for severe AS between May 2009 and January 2020 with interpretable electrocardiogram were included. Patients were divided into 2 groups according to the presence of fQRS. Kaplan-Meier survival analyses were used to detect cumulative survival rates. Univariable and multivariable Cox proportional hazards models were used to determine the predictors of all-cause mortality. RESULTS: fQRS occurred in 126 (43.5%) patients. A total of 59 (20.4%) patients died over a follow-up period of 54 ± 32 months. All-cause mortality was higher in the fQRS group (23 [14.1%] vs 36 [28.6], log-rank test P = 0.002) in the long term. The presence of fQRS [hazard ratio (HR): 1.802, confidence interval (CI): 1.035-3.135, P = 0.037], electrocardiographic left ventricular strain (HR: 1.836, CI: 1.036-3.254, P = 0.038) and history of stroke or transient ischaemic attack (HR: 3.130, CI: 1.528-6.412, P = 0.002) were independent predictors of all-cause mortality in the multivariable Cox regression model. CONCLUSIONS: fQRS is associated with a 1.8-fold increase in long-term mortality in patients undergoing isolated SAVR for severe AS. Detecting fQRS in electrocardiograms may provide prognostic information about the long-term outcomes.

Relação entre o Realce Tardio pelo Gadolínio e os Parâmetros de Repolarização Ventricular em Pacientes com Insuficiência Cardíaca com Fração de Ejeção Reduzida / Relationship between Late Gadolinium Enhancement and Ventricular Repolarization Parameters in Heart Failure Patients with Reduced Ejection Fraction

Resumo Fundamento A insuficiência cardíaca com fração de ejeção reduzida (ICFEr) é uma doença de alta prevalência que requer hospitalizações repetidas e causa morbimortalidade significativa. Portanto, o reconhecimento precoce de preditores de resultados desfavoráveis é essencial para o manejo do paciente. Objetivo O objetivo do presente estudo é investigar a relação entre realce tardio pelo gadolínio (RTG) detectado por ressonância magnética cardíaca (RMC) e os parâmetros de repolarização, como o intervalo QT corrigido (QTc), intervalo Tp-e, ângulo QRS-T frontal detectado pelo eletrocardiograma (ECG) de 12 derivações na ICFEr. Método Neste estudo observacional, retrospectivo, de centro único, foram incluídos 97 pacientes consecutivos com ICFEr submetidos à RMC. A população do estudo foi dividida em dois grupos, de acordo com a presença de RTG. Foram registradas medidas ecocardiográficas e de RMC e características demográficas. Os intervalos QTc, intervalos Tp-e, e ângulos QRS-T frontais foram calculados a partir do ECG. Um valor de p <0,05 foi considerado estatisticamente significativo. Resultados O RTG foi detectado em 52 (53,6%) de 97 pacientes com ICFEr. Os intervalos QTc (p=0,001), intervalos Tp-e (p<0,001), e os ângulos QRS-T frontais (p<0,001) foram significativamente maiores no grupo RTG quando comparados ao grupo não-RTG. Na análise de regressão univariada realizada para investigar os preditores de RTG na ICFEr, todos os três parâmetros de repolarização alcançaram valores significativos, mas na análise multivariada o único parâmetro de repolarização que permaneceu significativo foi o intervalo Tp-e (OR = 1,085 IC 95% 1,032-1,140, p=0,001). Conclusão Com o prolongamento do intervalo Tp-e, pode-se prever a presença de fibrose miocárdica, a qual é um substrato arritmogênico, em pacientes com ICFEr.

Abstract Background Heart failure with reduced ejection fraction (HFrEF) is a highly prevalent disease that requires repeating hospitalizations, causes significant morbidity and mortality. Therefore, early recognition of poor outcome predictors is essential for patient management. Objective The aim of the present study is to investigate the relationship between late gadolinium enhancement (LGE) detected by cardiac magnetic resonance (CMR) and repolarization parameters such as corrected QT (QTc) interval, Tp-e interval, frontal QRS-T angle detected by 12 lead electrocardiograph (ECG) in HFrEF. Method In this single-center, retrospective observational study included 97 consecutive HFrEF patients who had CMR scan. Study population was divided into two groups according to the presence of LGE. Echocardiographic and CMR measurements and demographic features were recorded. QTc intervals, Tp-e intervals, frontal QRS-T angles were calculated from the ECG. A p-value less than 0.05 was considered statistically significant. Results LGE was detected in 52 (53.6%) out of 97 HFrEF patients. QTc intervals (p=0.001), Tp-e intervals (p<0.001), frontal QRS-T angles (p<0.001) were found to be significantly higher in LGE group when compared to non-LGE group. In univariate regression analysis which was performed to investigate the predictors of LGE in HFrEF, all three repolarization parameters were reached significant values but in multivariate analysis the only repolarization parameter remained significant was Tp-e interval (OR=1.085 95% CI 1.032-1.140, p=0.001). Conclusion With the prolongation of the Tp-e interval, the presence of myocardial fibrosis which is an arrhythmogenic substrate, can be predicted in patients with HFrEF.

Predictors of long-term mortality in acute ST-elevation myocardial infarction patients undergoing emergent coronary artery bypass graft surgery.

OBJECTIVE: Coronary artery bypass graft (CABG) surgery as a primary treatment for acute ST-elevation myocardial infarction (STEMI) is still debated. This study aimed to evaluate the predictors of long-term mortality in STEMI patients undergoing emergent CABG. To the best of our knowledge, this is the first study to evaluate the long-term mortality predictors in patients with STEMI revascularized by primary CABG. METHODS: This retrospective study included 88 consecutive patients with STEMI, who did not qualify for primary percutaneous intervention and required emergent CABG between 2010 and 2017. The study population was divided into the following 2 groups: survivors and nonsurvivors. The 2 groups were compared in terms of demographics, preoperative, intraoperative, and postoperative characteristics. RESULTS: 23 of the 88 patients, died during the median 92.8 (69.0-105.1) months of follow-up. Data were evaluated with univariate and multivariate analyses. Killip class (p<0.001) was found to be an independent predictor of long-term all-cause mortality in patients with STEMI revascularized by CABG, and mortality rates increased significantly as Killip class increased (log-rank test, p<0.001). Moreover, age (p=0.044) was found to be an independent predictor of long-term mortality. Left ventricular ejection fraction, glomerular filtration rate, glucose levels, and left anterior descending artery to the left internal mammary artery graft usage (p=0.001, p=0.009, p<0.001, and p=0.039, respectively) were significantly associated with long-term all-cause mortality for our study population. CONCLUSION: Killip class was found to be an independent predictor of long-term all-cause mortality in patients with STEMI who underwent emergent CABG. The patients' admission status may give valuable information about long-term mortality.

Epicardial adipose tissue volume predicts long term major adverse cardiovascular events in patients with Type 2 diabetes.

OBJECTIVE: Epicardial adipose tissue (EAT) is a metabolically active visceral fat depot that plays an important role in coronary atherosclerosis. In this study, our aim was to investigate the relationship between long-term major adverse cardiovascular events (MACEs) and EAT volume detected by coronary computed tomography angiography (CCTA) in patients with Type 2 diabetes mellitus (T2-DM) without previous coronary events. METHODS: A total of 127 patients with diabetes who underwent CCTA between 2012 and 2014 were enrolled retrospectively. The study population was divided into 2 groups according to whether they experienced or did not experience MACE, which was defined as cardiac death, non-fatal myocardial infarction or unstable angina requiring hospitalization, coronary revascularizations (percutaneous coronary intervention or coronary artery bypass grafting surgery), heart failure, peripheral arterial disease, or ischemic stroke. In both groups, EAT volumes were measured by CCTA. RESULTS: During 60±7 months follow-up period, 22 participants experienced MACEs. Data were evaluated with univariate and multivariate analyses and receiver operating characteristic (ROC) analysis. Age, male sex, coronary artery disease, hemoglobin A1c, glucose, creatinine, C- reactive protein, and cholesterol levels were found to be associated with MACE. EAT volume (odds ratio [OR]: 1.027; 95% confidence interval [CI]: 1.010‒1.044, p=0.002) and low-density lipoprotein (OR: 1.015; 95% CI: 1.000‒1.030, p=0.050) were found to be independent predictors for MACE. ROC analysis indicated that EAT volumes >123.2 mL had a 72.7% sensitivity and a 77.1% specificity for predicting long-term MACE in patients with T2-DM (area under the curve: 0.820; 95% CI: 0.733-0.908). CONCLUSION: EAT volume is an independent predictor of long-term MACE in patients with T2-DM without previous coronary events. EAT volume may be used additionally in risk stratification for MACE besides the well-known vascular risk factors in patients with T2-DM.

Prognostic influence of objective nutritional indexes on mortality after surgical aortic valve replacement in elderly patients with severe aortic stenosis (from the nutrition-SAVR trial).

AIM: Several scoring systems, such as controlling nutritional status (CONUT) score, geriatric nutritional risk index (GNRI), and prognostic nutritional index (PNI), have been previously described to show nutritional status. In the present study, we aimed to investigate the value of these scoring systems in predicting in-hospital and long-term mortality in patients undergoing surgical aortic valve replacement (SAVR). METHODS: PNI, GNRI, and CONUT were determined using the receiver operator characteristics curve analysis in 150 consecutive elderly patients (age: 70 (66-74) years, male: 78) who underwent SAVR due to degenerative severe aortic stenosis (AS). Patients were divided into two groups according to cutoff values from these indexes. RESULTS: During the 50 ± 31 months follow-up period, a total of 36 (24%) patients died. 30-day mortality, 1-year mortality, and total mortality were significantly higher in lower PNI, lower GNRI, and higher CONUT groups. PNI cutoff value was 49.2, GNRI cutoff value was 102.5, and CONUT cutoff value was 1.5. PNI ≤ 49.2, GNRI ≤ 102.5, and CONUT > 1.5 values were found to be independent predictors of total mortality even after risk adjustment. In addition, in the mortality group, PNI (53.7 ± 5.9 vs. 47.4 ± 6.3; p < .001) and GNRI (108 ± 10 vs. 99 ± 6.3); p < .001) were significantly lower, while CONUT score (1 [0-2] vs. 2 [0.2-3]; p < .001) was significantly higher. CONCLUSION: Objective nutritional indexes including CONUT score, PNI, and GNRI are important prognostic factors and those indexes should be part of frailty assessment in patients with severe AS.

Determination of Cerebrovascular Accident Predictors in Patients with New-Onset Atrial Fibrillation After Coronary Artery Bypass Graft Surgery.

BACKGROUND: Postoperative atrial fibrillation (POAF) is associated with an increased risk of short and long-term stroke. Our aim is to identify the independent predictors of cerebrovascular accident (CVA) development in the patients who underwent isolated coronary artery bypass graft (CABG) surgery and developed POAF which lasted within 48 h. METHOD: 301 consecutive patients who underwent isolated CABG surgery in our institution between January 2015 and September 2019 and developed POAF which lasted within 48 h, were retrospectively analyzed. Oral anticoagulant (OAC) treatment was not started in any of these patients, and those who received OAC during follow-ups, were excluded from the study. The predictors of CVA development after mean 32.1± 17.9 months follow-up, were determined by using the Cox proportional hazards model. RESULTS: 20 (6.6%) patients developed CVA, in which 6 (2.0%) of them were in-hospital events. As a result of the multivariate analysis, being over 70 year-old, history of CVA, hypertension (HT), and left ventricular ejection fraction (LVEF) < 45% were determined as the independent predictors of CVA development over time. Having at least two of these factors could predict CVA development with sensitivity of 95.0% and specificity of 82.2%. This predictive value was better than the value obtained with CHA2DS2-VASc score. CONCLUSION: The risk factors which we have obtained, might be used to evaluate the risk of CVA development over time in the patients who underwent isolated CABG surgery and developed POAF which lasted within 48 h.

Utility of logistic clinical SYNTAX score in prediction of in-hospital mortality in ST-elevation myocardial infarction patients undergoing emergent coronary artery bypass graft surgery.

AIM: The logistic clinical SYNTAX score (log CSS) is a combined risk scoring system including clinical and anatomic parameters; it has been found to be effective for the prediction of mortality in patients with ST-elevation myocardial infarction (STEMI). Coronary artery bypass grafting (CABG) in the primary treatment of acute myocardial infarction is still debated. In the present study, we aimed to evaluate the utility of log CSS to stratify the risk of in-hospital mortality in acute STEMI patients undergoing emergent CABG for primary revascularization. METHOD: In total, 88 consecutive patients with acute STEMI, who did not qualify for primary percutaneous coronary intervention and required emergent CABG were included in our study. Nine of 88 patients died during hospitalization. The study population was divided into two groups as in-hospital survivors and non-survivors. Log CSS and SYNTAX score (SS) were calculated for both groups and two groups were compared in terms of demographics, preoperative, intraoperative, postoperative characteristics, SS and log CSS. RESULTS: Log CSS was found to be an independent predictor of in-hospital mortality, log CSS > 10.5 had 89% sensitivity, 81% specificity (area under the curve: 0.927; 95% confidence interval: 0.855-0.993). Moreover, peak troponin level was an independent predictor of in-hospital mortality. Glucose level, cardiopulmonary resuscitation before operation, glomerular filtration rate, left ventricular ejection fraction, and Killip class were significantly associated with in-hospital mortality. CONCLUSION: Log CSS may improve the accuracy of risk assessment in patients who are undergoing emergent CABG for primary revascularization of STEMI.

The predictive value of CHADS2 score for subclinical cerebral ischemia after carotid artery stenting (from the PREVENT-CAS trial).

BACKGROUND: Carotid artery stenting (CAS) is being increasingly used as an alternative revascularization procedure to carotid endarterectomy; however, subclinical ischemic cerebral lesions after CAS remain as a matter of concern. Hence, we aimed to assess the clinical utility of the CHADS2 score in predicting subclinical ischemic events after CAS. METHODS: We prospectively evaluated 107 patients (mean age: 70.4 ± 6.6 years, male:77) who underwent CAS for carotid artery revascularization. The patients having symptomatic transient ischemic attack or stroke after CAS were excluded. The presence of new hyperintense lesion on diffusion-weighted imaging (DWI) without any neurological findings was considered as silent ischemia. Patients were classified into two groups as DWI-positive and DWI-negative patients. RESULTS: Among study population, 28 patients (26.2%) had subclinical embolism. The DWI-positive group had a significantly higher CHADS2 scores, older age, more frequent history of stroke, higher proportion of type III aortic arch, and longer fluoroscopy time than the DWI-negative group. Increased CHADS2 score was identified as one of the independent predictors of silent embolism (OR = 5.584; 95%CI: 1.516-20.566; p = .010), and CHADS2 score higher than 2.5 predicted subclinical cerebral ischemia with a sensitivity of 72% and a specificity of 71% (AUC: 0.793; 95% CI: 0.696 - 0.890; p < .001). CONCLUSIONS: CHADS2 score was able to predict the risk of periprocedural subclinical ischemic events in CAS and might be of clinical value in the management of patients with carotid artery stenosis.

Echocardiographic detection of left atrium and left ventricle tumoral invasion via the left upper pulmonary vein, leading to the diagnosis of lung cancer.

Left atrial (LA) invasion by lung cancer via hematogenous pathways is relatively uncommon. Herein we report the case of a 68-year-old male without any medical history, in whom lung cancer was diagnosed by transesophageal echocardiographic detection of the LA and left ventricle tumoral invasion via the left upper pulmonary vein. The primary source of tumor was found out by computed tomography.

The important role of central sensitization in chronic musculoskeletal pain seen in different rheumatic diseases.

OBJECTIVE: This study explored the role of central sensitization (CS) pain in patients with various rheumatic diseases using the CS inventory (CSI). METHODS: A total of 193 patients of mean age 50.72 ± 9.65 years were included; they were divided into four different groups in terms of their rheumatic diseases. Patients with rheumatoid arthritis (RA), spondyloarthropathy (SpA), osteoarthritis (OA), and fibromyalgia syndrome (FMS) were evaluated in tertiary care rheumatology/pain medicine settings. Disease duration and activity, the Bath Ankylosing Spondylitis Disease Activity Index, the Disease Activity Score-28, and pain severity (evaluated using a visual analog scale) were assessed, and the Turkish version of the CSI administered. RESULTS: CS syndromes were present in almost half the patients (45% of SpA, 41% of RA, 62% of OA, and 94% of FMS patients). We found no significant relationship between disease activity and the CSI-A scores in SpA or RA patients (p = 0.731 and p = 0.390, respectively). As expected, the CSI-A scores were highest in the FMS group (p = 0.000), but were similar in the other groups (p < 0.05). CS-related syndromes (CSI-B conditions) were present at similar frequencies in the RA, SpA, and OA groups, but were less common in the FMS group (p = 0.000). CONCLUSIONS: The CSI usefully detects CS pain in patients with rheumatic diseases. Treatment of such pain can enhance the quality of daily life in patients with rheumatic diseases.Key Point• Central sensitization pain is common in patients with rheumatic diseases including rheumatoid arthritis, spondyloarthropathies, and osteoarthritis.

A rare complication of mitral valve replacement: Iatrogenic aortic valve perforation.

Iatrogenic aortic valve injury after mitral valve surgery is a well-known but rare complication. Herein, we report a 62-year-old male patient who underwent mitral valve replacement surgery 12 years ago and developed moderate to severe aortic regurgitation immediately after surgery.

Initial inferior vena cava and aorta diameter parameters measured by ultrasonography or computed tomography does not correlate with vital signs, hemorrhage or shock markers in trauma patients.

BACKGROUND: Ultrasonography (US) is noninvasive, readily available, and cheap. The diameter of inferior vena cava (dIVC) and its respiratory variation were proposed as a good surrogate of the hemodynamic state. However, recent studies have shown conflicting results, and the value of IVC-derived parameters in the estimation of fluid status and hemorrhage remains unclear. METHODS: This was an observational study of trauma patients who presented to emergency department. dIVC and aorta diameter (dAorta) were measured at the initial US and CT in all patients. The correlation of these measurements and all parameters derived from those measurements along with the initial vital signs and laboratory values of hemorrhage (hemoglobin, hematocrit) and shock (lactate, base excess) were assessed. US and CT values were also compared for accuracy using Bland-Altman analysis. RESULTS: The final study population was 140, with a mean age of 38 years and 79.3% were male. dIVC and dAorta did not have any clinically significant correlation with any of the vital signs or laboratory values of hemorrhage or shock when measured by US or CT. A good and significant correlation was observed between dIVC and dAorta measured by US and CT. CONCLUSION: The value of an initial and single measurement of IVC and aorta parameters in the evaluation of trauma patients should be questioned. However, the change in the measured parameters may be of value and should be investigated in further studies.
