RESUMEN
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.

BACKGROUND: Silent new cerebral ischemic lesions (sNCIL) are a common complication of carotid artery stenting (CAS) that can lead to an increase in morbidity and mortality. We aimed to evaluate the impact of hematological parameters on sNCIL in patients undergoing CAS. METHODS: We retrospectively evaluated 103 patients who underwent CAS, with a mean age of 70.5 ± 6.7 years, and 31 (20.1 %) of whom were female. Stents were placed for internal carotid artery revascularization. The presence of new hyperintense lesions on diffusion-weighted imaging (DWI) without neurological symptoms was considered as sNCIL in cases without apparent neurological findings. Patients were categorized into two groups based on DWI results: positive (29) and negative (74). RESULTS: In the study population, sNCIL was observed in 29 patients (28.2 %). The DWI-positive group exhibited significantly higher Plateletcrit (PCT) levels, advanced age, and a lack of embolic protection device usage compared to the DWI-negative group. The Receiver Operating Characteristic (ROC) analysis identified a PCT value of 0.26 as the optimal threshold, detecting the development of sNCIL with a sensitivity of 75.9 % and specificity of 59.1 % (AUC: 0.700; 95 % CI: 0.594-0.806, p = 0.002). CONCLUSION: To be determined by a simple blood parameter, PCT can predict the risk of sNCIL before CAS and holds clinical value in the treatment of patients with carotid artery stenosis.

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.

BACKGROUND: This study aimed to evaluate the efficacy and safety of Pro-Glide, a suture-mediated vascular closure device, regarding technical success and complications in patients who had undergone aortic intervention and had previous groin intervention (PGI). METHODS: One hundred and thirty-five patients who underwent percutaneous thoracic endovascular aortic repair via the femoral artery and were closed with the Pro-Glide device were analyzed retrospectively. PGI was defined as a history of open surgical access to the femoral artery or wide sheath (>18 F) placement due to endovascular or valvular intervention. The patients were divided into two groups 38 cases with PGI and 97 cases without PGI. RESULTS: The overall success rate of closure of the femoral artery with Pro-Glide was not statistically significant between the two groups (93.8% vs 92.1%, p = .711). Sheath sizes were compared between the groups and PGI (+) group had significantly higher sheath sizes compared to PGI (-) group (24.3 ± 1.1 F vs 23.8 ± 1.0 F, p = .011). Three patients in the PGI (+) group and six patients in the PGI (-) group experienced technical failure of the percutaneous femoral approach. Femoral complications were seen after the procedures in four patients in the PGI (+) group and four in the PGI (-) group. The PGI (+) group had a higher complication rate when compared to the PGI (-) group; however, this was not statistically significant (p = .181). CONCLUSION: The present study was conducted on a significantly larger sample compared to previous studies and the findings suggest that the Pro-Glide vascular closure device is a safe option for patients with a history of PGI and may not be considered as a contraindication.
RESUMEN
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.

BACKGROUND: One of the hallmarks of frailty in patients with severe aortic stenosis (AS) is malnutrition, for which one of the most up-to-date scoring systems is the Naples prognostic score (NPS). This study sought to investigate the predictive role of the NPS in determining mortality in patients undergoing transcatheter aortic valve replacement (TAVR) under long-term follow-up. METHODS: A total of 430 consecutive patients with symptomatic severe AS who underwent TAVR were included retrospectively. The primary endpoint of the study was the long-term all-cause mortality. The study population was divided into two groups according to the NPS value, including Group 1 (NPS 0-2) and Group 2 (NPS 3-4). RESULTS: The all-cause mortality occurred in 250 patients (62.5%) patients during a follow-up time of 40.6 (22.0-69.4) months. During the follow-up period, all-cause mortality was higher in Group 2 compared with Group 1 (87.9% vs. 42.9%, p < 0.001). Older age (p < 0.001), chronic obstructive pulmonary disease (p = 0.015), left ventricular ejection fraction (p = 0.021), and being in Group 2 (high NPS) (hazard ratio: 7.058, 95% confidence interval: 5.174-9.629, p < 0.001) were found to be independent predictors of all-cause mortality at long-term follow-up. CONCLUSION: The NPS as a malnutrition and inflammation marker in patients with severe aortic stenosis who underwent TAVR provides valuable information for all-cause mortality under long-term follow-up.

BACKGROUND: The renin-angiotensin-aldosterone system was shown to be activated in severe COVID-19 infection. We aimed to investigate the relationship between angiotensin converting enzyme (ACE) levels, ACE gene polymorphism, type 2 diabetes (T2DM), and hypertension (HT) and the prognosis of COVID-19 infection. METHODS: This cross-sectional study analyzed the clinical features of adult patients with SARS-CoV-2 infection. ACE gene analysis and ACE level measurements were performed. The patients were grouped according to ACE gene polymorphism (DD, ID or II), disease severity (mild, moderate, or severe), and the use of dipeptidyl peptidase-4 enzyme inhibitor (DPP4i), ACE-inhibitor (ACEi) or angiotensin receptor blocker (ARB). Intensive care unit (ICU) admissions and mortality were also recorded. RESULTS: A total of 266 patients were enrolled. Gene analysis detected DD polymorphism in the ACE 1 gene in 32.7% (n = 87), ID in 51.5% (n = 137), and II in 15.8% (n = 42) of the patients. ACE gene polymorphisms were not associated with disease severity, ICU admission, or mortality. ACE levels were higher in patients who died (p = 0.004) or were admitted to the ICU (p<0.001) and in those with severe disease compared to cases with mild (p = 0.023) or moderate (p<0.001) disease. HT, T2DM, and ACEi/ARB or DPP4i use were not associated with mortality or ICU admission. ACE levels were similar in patients with or without HT (p = 0.374) and with HT using or not using ACEi/ARB (p = 0.999). They were also similar in patients with and without T2DM (p = 0.062) and in those with and without DPP4i treatment (p = 0.427). ACE level was a weak predictor of mortality but an important predictor of ICU admission. It predicted ICU admission in total (cutoff value >37.092 ng/mL, AUC: 0.775, p<0.001). CONCLUSION: Our findings suggest that higher ACE levels, but not ACE gene polymorphism, ACEi/ARB or DPP4i use, were associated with the prognosis of COVID-19 infection. The presence of HT and T2DM and ACEi/ARB or DPP4i use were not associated with mortality or ICU admission.

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.

OBJECTIVE: To examine the validity and reliability of 3-Meter Backwalk Test (3MBWT) in children with Cerebral Palsy (CP). METHODS: Study included 55 children with CP with the mean age of 12.34 ± 3.78 years, at Expanded and Revised Gross Motor Functional Classification System (GMFCS-E&R) I and II levels. Intraclass Correlation Coefficient (ICC) was used for the intra-rater and inter-rater reliability of 3MBWT according to the GMFCS-E&R levels. MDC estimates were calculated using baseline data. Convergent validity of 3MBWT was evaluated with its correlation between the Timed Up and Down Stairs Test (TUDS), Pediatric Balance Scale (PBS), Timed Up and Go Test (TUG), Pediatric Reach Test (PRT), Four Square Step Test (FSST). RESULTS: Intra-rater and inter-rater reliability of 3MBWT was determined excellent at GMFCS-E&R I (Intra-rater ICC = 0.981-0.987, inter-rater ICC = 0.982-0.993), and GMFCS-E&R II (ICC = 0.927-0.933, ICC = 0.954-0.968). Intra-rater MDC values for GMFCS-E&R I were 1.17-1.22 s (s); 1.40-1.42 s for GMFCS-E&R II. Inter-rater MDC values for GMFCS-E&R I were 1.00-1.28 s, and MDC values for GMFCS-E&R II were 1.08-1.22 s. There was strong correlation between 3MBWT and PBS, TUG, and FSST in GMFCS-E&R I, moderate correlation between 3MBWT and TUDS, strong correlation between BBS, moderate correlation between TUG, and strong correlation between FSST in GMFCS-E&R II (p < 0.05). CONCLUSION: The 3MBWT was found to be valid and reliable in children with CP. According to the MDC results, small differences in CP children can be adequately detected with 3MBWT. The 3MBWT also may add some more information on to GMFCS (E&R) data for following the disease progression as well as rehabilitation responses. TRIAL REGISTRATION NUMBER: NCT04653363.

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.

Although many efforts have been made to characterize the functional properties of hazelnut constituents (mainly its oil, protein, and phenolics), those of its dietary fiber (DF) have not been elucidated yet. Here, we aimed to investigate the impact of DF of natural and roasted hazelnuts, and hazelnut skin on the colonic microbiota in vivo (C57BL/6J mouse models) by determining their composition through 16S rRNA sequencing and microbial short-chain fatty acids (SCFAs) using gas chromatography. Our results revealed that hazelnut DF generally showed an acetogenic effect in male mice, whereas the same trend was not observed in the female counterparts. The 16S rRNA sequencing results showed that hazelnut DF, especially that of natural hazelnuts, increased the relative abundances of Lactobacillus-related OTUs that have probiotic potential. LEfSe analysis indicated that, for female mice, Lachnospiraceae, Prevotella, Ruminococcaceae, and Lactobacillus were found to be discriminators for DF of natural hazelnuts, roasted hazelnuts, hazelnut skin, and control, respectively, whereas Bacteroides, Lactobacillus, Prevotella, and Lactococcus were the discriminators for the male counterparts, respectively. This study clearly indicates that, although the roasting process slightly alters the functionalities, hazelnut DF favors beneficial microbes and stimulates beneficial microbial metabolites in the colon in a sex-dependent way, which could be a contributing factor to the health-promoting effects of hazelnuts. Furthermore, hazelnut skin, a byproduct of the hazelnut industry, was found to have potential to be utilized to produce functional DF targeting colonic health.

To identify the sources of contamination with potentially toxic elements (PTEs) in roadside orchard soils and to evaluate the potential ecological and environmental impacts in Gaziantep, soil samples from 20 mixed pistachio and olive orchards on roadsides with different traffic densities and at different distances to the roads were analyzed. Concentrations were 23,407.36 ± 4183.76 mg·kg-1 for Fe, 421.78 ± 100.26 mg·kg-1 for Mn, 100.20 ± 41.92 mg·kg-1 for Ni, 73.30 ± 25.58 mg·kg-1 for Cr, 65.03 ± 12.19 mg·kg-1 for Zn, 60.38± 7.91 mg·kg-1 for Pb, 17.74 ± 3.35 mg·kg-1 for Cu, 14.93 ± 4.94 mg·kg-1 for Co, and 0.30 ± 0.12 mg·kg-1 for Cd. It was found that the Ni content in 51% and the Cr content in 18% of orchard soils were above the legal limits for agricultural soils (pH > 6) in Türkiye. Factor analysis (FA) showed that Co, Cr, Cu, Fe, Mn, Ni, and Pb loaded on the first factor (FC1), while Cd and Zn loaded mostly on the second factor (FC2). It was found that Cr, Ni, and Pb were primarily enriched through pedogenic processes, whereas Cd most likely originated from agricultural activities, while the impact of road traffic as source of PTE contamination was insignificant. It has been revealed that the soils are of low quality for agricultural production due to PTE contamination (PIave ≥ 1). The SOPI values from environmental and ecological individual indices showed that the soil pollution level was moderate for Cd, Ni, and Pb, and low for Cr. The soil pollution index (SOPI) proved to be suitable for evaluating and comparing PTE pollution in regions with different soil properties.

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.

BACKGROUND: The prognostic value of C-reactive protein/albumin ratio (CAR) is of import in cardiovascular diseases. Our aim was to evaluate the impact of the CAR in patients with asymptomatic abdominal aortic aneurysm (AAA) undergoing endovascular aneurysm repair (EVAR). MATERIAL AND METHOD: We retrospectively evaluated 127 consecutive patients who underwent technically successful elective EVAR procedure between December 2014 and September 2020. The optimal CAR cut-off value was determined by using receiver operating characteristic (ROC) curve analysis. Based on the cut-off value, we investigated the association of CAR with long-term all-cause mortality. RESULTS: 32 (25.1%) of the patients experienced all-cause mortality during a mean 32.7 ± 21.7 months' follow-up. In the group with mortality, CAR was significantly higher than in the survivor group (4.63 (2.60-11.88) versus 1.63 (0.72-3.24), p < 0.001). Kaplan-Meier curves showed a higher incidence of all-cause mortality in patients with high CAR compared to patients with low CAR (log-rank test, p < 0.001). Multivariable Cox regression analysis revealed that glucose ≥ 110 mg/dL (HR: 2.740; 95% CI: 1.354-5.542; p = 0.005), creatinine ≥ 0.99 mg/dL (HR: 2.957, 95% CI: 1.282-6.819, p = 0.011) and CAR > 2.05 (HR: 8.190, 95% CI: 1.899-35.320, p = 0.005) were the independent predictors of mortality. CONCLUSION: CAR was associated with a significant increase in postoperative long-term mortality in patients who underwent EVAR. Preoperatively calculated CAR can be used as an important prognostic factor.

OBJECTIVES: Treatment of abdominal aortic aneurysms (AAA) with endovascular aortic repair (EVAR) has become quite common in recent years. This method, which has many advantages compared to the open surgical procedure, also has some complications. One of these complications is acute kidney injury (AKI). ACEF (age, creatinine, and ejection fraction) score, which is gaining popularity, can be an easy-to-use and cost-effective method in detecting this condition that causes increased morbidity and mortality. We aimed to evaluate whether this ACEF score may predict a development of AKI in patients who underwent EVAR. METHODS: A total of 133 consecutive patients with AAA who underwent EVAR were analyzed. The primary endpoint of the study was the development of AKI. The best cut-off value for the ACEF score to predict the development of AKI was calculated and according to this value, the patients were divided into two groups as those with high ACEF scores and those with low ACEF scores. ACEF score was calculated by the formula of age/EF + 1 (if baseline creatinine > 2 mg/dL). RESULTS: After the exclusion criteria, a total of 118 patients were included in the study, and 20 (16.9%) of them developed AKI after EVAR. In the ROC curve analysis, a cut-off value of 1.34 was found for the ACEF score, and scores above this value were found to be independent predictors of AKI development after EVAR. In addition to the ACEF score, the contrast media volume was also found to be an independent predictor of the development of AKI. CONCLUSION: In conclusion, ACEF is a simple and effective scoring system in patients undergoing EVAR. To the best our knowledge, our study is the first study which applies ACEF score to predict AKI in EVAR patients.

INTRODUCTION: Chronic obstructive pulmonary disease (COPD) is considered a major risk factor for postoperative complications after transcatheter aortic valve implantation (TAVI). To date, there is no clear consensus on the best anesthesia management for these patients. We aimed to investigate the effects of types of anesthesia on clinical outcomes in patients with severe COPD undergoing TAVI. METHODS: This is a single-center, retrospective study comparing conscious sedation (CS) versus general anesthesia (GA) in 72 patients with severe COPD who underwent TAVI. The primary endpoints were 30-day all-cause mortality and postoperative pulmonary complications. RESULTS: The main outcome of interest of this study was that the frequency of pulmonary complications was statistically higher in the GA group (21.4% vs 3.3%, p = 0.038). These differences are most likely attributed to the GA because of prolonged mechanical ventilation, and longer ICU stay (2 (1.2-3) vs 2.5 (2-4) days, p = 0.029) associated with an increased risk of nosocomial infections. There were no significant differences in procedure complications and 30-day mortality between the two groups (GA; 19% vs CS; 13.3%, p = 0.521). One-year survival rates, compared by Kaplan-Meier analysis, were similar between groups (log-rank p = 0.733). CONCLUSION: In aortic stenosis patients with severe COPD undergoing TAVI, the use of GA compared with CS was associated with higher incidences of respiratory-related complications, and longer ICU length of stay. CS is a safe and viable option for these patients and should be considered the favored approach.

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.

BACKGROUND: The right fibrous trigone, which the His bundle penetrates, is part of the subaortic area adjacent to the membranous septum. Structural alterations of the right fibrous trigone may cause conduction disturbance as a result of compression in this area after transcatheter aortic valve implantation. This study analyzed the hypothesis of whether imaging parameters of the RFT could predict the risk of conduction disturbance after transcatheter aortic valve implantation. METHODS: We retrospectively examined 209 patients who underwent transfemoral transcatheter aortic valve implantationat a tertiary cardiac center. The different valve models were divided into 2 groups: self-expanding valve and balloon-expandable valve. Using pre-procedure computed tomography, we evaluated for the alterations of the right fibrous trigone. RESULTS: New conduction disturbance was seen in 75 of 209 (35.8%) patients. Receiver operating characteristics plots displayed a right fibrous trigone density of -6 Hounsfieldunit for SEV and -16 Hounsfield unit for balloon-expandable valve as the optimal cut- off points for prediction conduction disturbance. In multiple regression analyses, the high density of RFT emerged as an independent predictor of conduction disturbance in both the self-expanding valve (odds ratio: 1.01, 95% CI: 1.01 to 1.02, P = 0.035) and bal- loon-expandable valve (odds ratio: 1.01, 95% CI: 1.01 to 1.03, P = 0.017) groups. A shorter membranous septum length and a greater implantation depth were also found to be significantly associated with a higher incidence of conduction disturbance in both trans- catheter aortic valve implantation groups. CONCLUSION: High density of right fibrous trigone is independently associated with con- duction disturbance after transcatheter aortic valve implantation, and its pre-proce- dure computed tomography evaluation can help predict the new-onset of conduction disturbance.
