RESUMEN

INTRODUCTION: The rapid advancement of artificial intelligence and big data analytics, including descriptive, diagnostic, predictive, and prescriptive analytics, has the potential to revolutionize many areas of medicine, including nephrology and dialysis. Artificial intelligence and big data analytics can be used to analyze large amounts of patient medical records, including laboratory results and imaging studies, to improve the accuracy of diagnosis, enhance early detection, identify patterns and trends, and personalize treatment plans for patients with kidney disease. Additionally, artificial intelligence and big data analytics can be used to identify patients' treatment who are not receiving adequate care, highlighting care inefficiencies in the dialysis provider, optimizing patient outcomes, reducing healthcare costs, and consequently creating values for all the involved stakeholders. OBJECTIVES: We present the results of a comprehensive survey aimed at exploring the attitudes of European physicians from eight countries working within a major hemodialysis network (Fresenius Medical Care NephroCare) toward the application of artificial intelligence in clinical practice. METHODS: An electronic survey on the implementation of artificial intelligence in hemodialysis clinics was distributed to 1,067 physicians. Of the 1,067 individuals invited to participate in the study, 404 (37.9%) professionals agreed to participate in the survey. RESULTS: The survey showed that a substantial proportion of respondents believe that artificial intelligence has the potential to support physicians in reducing medical malpractice or mistakes. CONCLUSION: While artificial intelligence's potential benefits are recognized in reducing medical errors and improving decision-making, concerns about treatment plan consistency, personalization, privacy, and the human aspects of patient care persist. Addressing these concerns will be crucial for successfully integrating artificial intelligence solutions in nephrology practice.

RESUMEN

A surface water isolate of Raoultella sp. having both multidrug- and multimetal-resistant ability was isolated and identified as Raoultella planticola. R. planticola displayed resistance to 15 drugs like ampicillin, amoxicillin/clavulanic acid, aztreonam, erythromycin, imipenem, oxacillin, pefloxacin, penicillin, piperacillin, piperacillin/tazobactam, rifampin, sulbactam/cefoperazone, ticarsillin, ticarsillin/clavulanic acid, vancomycin, and to 11 heavy metals like aluminum, barium, copper, iron, lead, lithium, manganese, nickel, silver, strontium, and tin. The multidrug and multi-metal-resistant R. planticola may remain present in the environment for a long time. Due to a possible health risk of these pathogenic bacteria, a need exists for an accurate assessment of their acquired resistance to multiple drugs and metals.

RESUMEN

Introduction: More frequent and/or longer hemodialysis (HD) has been associated with improvements in numerous clinical outcomes in patients on dialysis. Home HD (HHD), which allows more frequent and/or longer dialysis with lower cost and flexibility in treatment planning, is not widely used worldwide. Although, retrospective studies have indicated better survival with HHD, this issue remains controversial. In this multicenter study, we compared thrice-weekly extended HHD with in-center conventional HD (ICHD) in a large patient population with a long-term follow-up. Methods: We matched 349 patients starting HHD between 2010 and 2014 with 1047 concurrent patients on ICHD by using propensity scores. Patients were followed-up with from their respective baseline until September 30, 2018. The primary outcome was overall survival. Secondary outcomes were technique survival; hospitalization; and changes in clinical, laboratory, and medication parameters. Results: The mean duration of dialysis session was 418 ± 54 minutes in HHD and 242 ± 10 minutes in patients on ICHD. All-cause mortality rate was 3.76 and 6.27 per 100 patient-years in the HHD and the ICHD groups, respectively. In the intention-to-treat analysis, HHD was associated with a 40% lower risk for all-cause mortality than ICHD (hazard ratio [HR] = 0.60; 95% confidence interval [CI] 0.45 to 0.80; P < 0.001). In HHD, the 5-year technical survival was 86.5%. HHD treatment provided better phosphate and blood pressure (BP) control, improvements in nutrition and inflammation, and reduction in hospitalization days and medication requirement. Conclusion: These results indicate that extended HHD is associated with higher survival and better outcomes compared to ICHD.

RESUMEN

OBJECTIVES: Systemic inflammation plays an important role in the pathogenesis of atherosclerosis in psoriasis patients. Therefore, persistent skin inflammation in psoriasis patients may contribute to the development of premature atherosclerosis, as it occurs in rheumatoid arthritis and systemic lupus erythematosus. We aimed to evaluate the relationship between subclinical atherosclerosis and psoriasis by using pulse wave velocity (PWV) and the measurement of carotid intima media thickness (CIMT) in psoriatic patients. STUDY DESIGN: Fifty-seven plaque-type psoriasis patients (31 males, 26 females; mean age 41±10.8 years) and 60 healthy individuals (32 males, 28 females; mean age 40±9.4 years) were included. Atherosclerotic risk factors were excluded in both of the groups. Demographic, bio-chemical data, psoriasis area and severity index (PASI) score of the psoriasis group, and disease duration were recorded. Carotid-femoral artery PWV and CIMT values were compared. RESULTS: PWV, and the maximum and average CIMT values of psoriasis patients were higher than those of the healthy group (PWV: 7.04±1.1 m/sn vs. 6.03±0.61 m/sn, p<0.001; maximum CIMT: 0.86±0.09 mm vs. 0.77±0.06 mm, p<0.001; mean CIMT: 0.73±0.09 mm vs. 0.66±0.06 mm p<0.001, respectively). Although there was no difference in the lipid levels of the groups, total/HDL cholesterol (4.40±1.26 vs. 3.88±1.18, p=0.02, respectively), and LDL/HDL cholesterol ratios (2.78±0.98 vs. 2.32±0.92, p=0.01, respectively) of the psoriasis group were higher than those of the healthy group. A positive correlation was observed between PASI and the PWV (r=0.417, p=0.001). CONCLUSION: Despite the nonexistence of atherosclerotic risk factors, the risk of development of atherosclerosis is higher in psoriasis patients compared to healthy individuals. In addition to damage of the artery wall caused by systemic inflammation, lipid metabolism disorders may contribute to the development of atherosclerosis in these patients.

RESUMEN

PURPOSE: The aim of this study was to reveal the first time synergistic effect of GP and selenium (Se) on 3T3 cells seeded on natural and non-cytotoxic porous scaffolds with poly(vinyl alcohol) (PVA) and gelatin (GE). METHODS: Electrospinning scaffolds were produced as PVA/GE/GA crosslinked with glutaraldehyde (GA) and freeze/dried scaffolds crosslinked with genipin (GP) were divided into two groups as PVA/GE/GP5 and PVA/GE/GP8. The scaffolds were investigated in terms of pore morphology, swell ratio, biodegradation, and biocompatibility. The biocompatibility of the material was tested in vitro by MTT assay on 1, 2, and 3 days to test the cell viability of 3T3 cells. RESULTS: It was observed that Se triggered the excellent cell growth and proliferation on electrospinning and freeze drying PVA/GE scaffolds. CONCLUSIONS: Selenium with PVA/GE scaffolds can be a promising candidate for wound healing application, as it significantly increases cell viability on scaffolds. It is thought that the synergistic effect of selenium with genipin may be an important step in tissue engineering applications. The preliminary study can be supported by in vivo studies in the future.

RESUMEN

BACKGROUND: The role of inflammation in the pathogenesis and progression of atherosclerosis has been increasingly discussed. Although the seroepidemiological studies have suggested a relationship between Helicobacter pylori (H. pylori) infection and atherosclerosis; the issue is still controversial. It is well known that abnormal lipid profil is related to atherosclerosis and the measurement of carotid-intima media thickness (CIMT) is one of the surrogate marker of atherosclerosis. The serum concentration of high-density lipoprotein (HDL-C) has been known to have an inverse correlation with the development of atherosclerosis. Paraoxonase-1 (PON1) is a major anti-atherosclerotic component of HDL-C. PON1 activity is related to lipid peroxidation and prospective cardiovascular risk. The aim of this study was to investigate CIMT and serum PON1 activities along with lipid parameters in H. pylori positive and negative subjects. METHODS: Thirty H. pylori positive subjects and thirty-one negative subjects were enrolled. H. pylori infection was diagnosed by the presence of positivity of stool H. pylori antigen test or Carbon 14 labeled urea breath test. Serum PON1 activity was measured spectrophotometrically. Traditional cardiovascular risk factors were investigated and laboratory analysis included measurement of serum triglycerides (TG), total cholesterol (TC), high-density lipoprotein (HDL-C) and low-density lipoprotein cholesterol (LDL-C). We assessed CIMT by high-resolution ultrasound of both common carotid arteries. RESULTS: We found that the mean and maximum values of right and overall CIMT in H. pylori positive subjects were significantly thicker than those of H. pylori negative subjects. There was no significant differences in serum HDL-C, LDL-C, TC levels and TC/HDL-C ratios between two groups. Serum TG levels of H. pylori positive subjects were significantly higher than those of H. pylori negative subjects (p = 0.014). We found that PON1 activities were significantly lower in H. pylori positive subjects compared with negative subjects. No significantly correlation was observed between PON1 and CIMT values. CONCLUSIONS: There is an increase in CIMT values in patients with H. pylori positive compared to H. pylori negative subjects. PON1 activity decrease significantly in H. pylori positive subjects. However, an association between PON1 and CIMT was not found. These data indicated that H. pylori may have a role in atherosclerotic processes, however, further studies are needed to evaluate the exact mechanisms.

RESUMEN

An electrochemical sensor composed of Nafion-graphene nanocomposite film for the voltammetric determination of caffeic acid (CA) was studied. A Nafion graphene oxide-modified glassy carbon electrode was fabricated by a simple drop-casting method and then graphene oxide was electrochemically reduced over the glassy carbon electrode. The electrochemical analysis method was based on the adsorption of caffeic acid on Nafion/ER-GO/GCE and then the oxidation of CA during the stripping step. The resulting electrode showed an excellent electrocatalytical response to the oxidation of caffeic acid (CA). The electrochemistry of caffeic acid on Nafion/ER-GO modified glassy carbon electrodes (GCEs) were studied by cyclic voltammetry and square-wave adsorption stripping voltammetry (SW-AdSV). At optimized test conditions, the calibration curve for CA showed two linear segments: the first linear segment increased from 0.1 to 1.5 and second linear segment increased up to 10 µM. The detection limit was determined as 9.1×10(-8) mol L(-1) using SW-AdSV. Finally, the proposed method was successfully used to determine CA in white wine samples.

RESUMEN

BACKGROUND/AIMS: Helicobacter pylori infection has been suggested to be associated with atherosclerosis. The issue is still controversial. It is well known that abnormal lipid profile and oxidative stress are related to atherosclerosis and the measurement of carotid intima-media thickness. The aim of this study was to investigate carotid intima-media thickness and oxidative stress along with lipid parameters in Helicobacter pylori-positive and -negative subjects. MATERIALS AND METHODS: Thirty Helicobacter pylori-positive subjects and 31 Helicobacter pylori-negative subjects were enrolled. Helicobacter pylori infection was diagnosed by noninvasive tests. Serum total oxidant status and total antioxidant capacity levels were measured. Oxidative stress index was calculated based on total oxidant status/total antioxidant capacity ratio. Traditional cardiovascular risk factors were recorded, and laboratory analysis included measurement of serum triglycerides, high-density lipoprotein cholesterol and low-density lipoprotein cholesterol. carotid intima media thickness was assessed by high-resolution ultrasound. RESULTS: We found that the mean and maximum values of right and overall carotid intima-media thickness in Helicobacter pylori-positive subjects were significantly thicker than in Helicobacter pylori-negatives (p < 0.05). Serum triglycerides levels of Helicobacter pylori-positive subjects were significantly higher than in Helicobacter pylori-negatives (p < 0.05). Total oxidant status, total antioxidant capacity and oxidative stress index values were significantly higher in Helicobacter pylori-positive subjects compared with negatives (p < 0.05). No significant correlation was observed between oxidative stress markers and carotid intima-media thickness values. CONCLUSIONS: Carotid intima-media thickness, total oxidant status, total antioxidant capacity, oxidative stress index, and triglycerides values are increased in Helicobacter pylori-positive subjects compared to Helicobacter pylori-negatives. These data indicated that Helicobacter pylori infection may have a role in atherosclerotic processes.

RESUMEN

Congential aorta-right atrial tunnel (ARAT) is a rare anomaly. Many patients are asymptomatic and diagnosis can be made during investigation of systolic and diastolic continuous murmur heard on cardiac oscultation. In some patients, symptoms such as palpitation, dyspnea, and fatigue on exertion can be seen. With transthoracic and transesophageal echocardiography diagnosis can usually be made, but more definite diagnosis is possible with coronary angiography, aortography, and computerized tomography. Herein with the data from current literature we will discuss a case who was admitted to our clinic with symptoms of heart failure and diagnosed with ARAT.
