ABSTRACT

Cardiac surgery (CS) with extracorporeal circulation (ECC), induces intense oxidative stress (OS) and systemic inflammatory response (SIR), which may seriously affect postoperative lung function. We aimed to test if high parenteral (200 mg/kg/24 h) daily doses of Vitamin C (VitC), given within 48 h after the beginning of the operation, may reduce the incidence and severity of postoperative pulmonary complications (PPCs) in CS patients. This single-center, prospective, randomized, single-blinded, interventional trial included 150 patients, assigned to control Group A (n = 75) and interventional Group B (n = 75). Group B intraoperatively received one-fourth (i.e., 50 mg/kg) of the planned daily Vit C dose, divided into three equal parts and diluted in 10 mL of normal saline, while Group A received an equal volume of normal saline at the same time frames (i.e., the induction of anesthesia, aortic cross-clamp release, and sternal closure). After 6 h from the first intraoperative dose, the following regimen was applied: Group B: 50 mg/kg, 30 min i.v. infusion of VitC in 50 mL of normal saline, every 6 h, for the next 48 h, and Group A: 30 min i.v. infusion of an equal volume of normal saline every 6 h, for the next 48 h. Modified Kroenke's score was used to determine the incidence and severity of PPCs. The overall incidence of PPCs was 36.7% and was significantly lower in Group B (13.3% vs. 60.0%, p < 0.001). The PPCs severity score was also significantly lower in Group B (1 vs. 3, p < 0.001). In addition, patients from Group B had significantly less damaged lungs, better postoperative renal function, shorter ICU stays, fewer ICU re-admissions, and lower hospital mortality. No VitC-related adverse effects were recorded. High parenteral daily VitC doses given within 48 h after the beginning of CS are safe and effective in reducing the incidence and severity of PPCs. A multicenter RCT is needed to confirm these results.

ABSTRACT

OBJECTIVE: Degenerative aortic stenosis and coronary artery disease are considered to be the most prevalent cardiovascular diseases in industrialized countries. This study aims to determine the change over time in von Willebrand factor antigen, von Willebrand factor activity, and factor VIII and where there is a correlation with total post-operative drainage. METHODS: The single-center retrospective study included 203 consecutive patients (64.5% male), undergoing coronary artery bypass surgery between March 1, 2019 and June 30, 2020 at the University Clinical Center of Serbia in the Clinic for Cardiac Surgery in Belgrade, Serbia. All patients 18 years or older who presented with isolated, hemodynamically significant aortic stenosis were included. The control group consisted of patients who presented with only coronary artery disease. RESULTS: Between patients with only coronary artery disease and patients with coronary artery diseases and aortic stenosis, there was a statistically significant difference between pre-op and 1-month post-op fibrinogen, factor VIII, von Willebrand factor antigen, and von Willebrand factor (p < 0.001), post-op drainage, with overall lower drainage in coronary artery disease patients, and consistent increase in von Willebrand factor antigen, von Willebrand factor activity, and Factor VIII post-operatively in patients with coronary artery diseases and aortic stenosis. CONCLUSION: This study has shown that there is a correlation between von Willebrand factor antigen, von Willebrand factor activity and total drainage to the level of statistical significance in aortic stenosis patients and in the overall study population.

ABSTRACT

The aim of this study was to examine the incidence and significance of right heart failure (RHF) in the early and late phase of left ventricular assist device (LVAD) implantation with the identification of predictive factors for the development of RHF. This was a prospective observational analytical cohort study. The study included 92 patients who underwent LVAD implantation and for whom all necessary clinical data from the follow-up period were available, as well as unambiguous conclusions by the heart team regarding pathologies, adverse events, and complications. Of the total number of patients, 43.5% died. The median overall survival of patients after LVAD implantation was 22 months. In the entire study population, survival rates were 88.04% at one month, 80.43% at six months, 70.65% at one year, and 61.96% at two years. Preoperative RHF was present in 24 patients, 12 of whom died and 12 survived LVAD implantation. Only two survivors developed early RHF (ERHF) and two late RHF (LRHF). The most significant predictors of ERHF development are brain natriuretic peptide (BNP), pre-surgery RHF, FAC < 20%, prior renal insufficiency, and total duration of ICU stay (HR: 1.002, 0.901, 0.858, 23.554, and 1.005, respectively). RHF following LVAD implantation is an unwanted complication with a negative impact on treatment outcome. The increased risk of fatal outcome in patients with ERHF and LRHF after LVAD implantation results in a need to identify patients at risk of RHF, in order to administer the available preventive and therapeutic methods.

ABSTRACT

OBJECTIVE: The objective of this prospective study was to evaluate the characteristics (positive and negative) of Perceval S valve in patients undergoing aortic valve replacement with a biological prosthesis. The study included 67 patients operated on at our institution and a mean follow-up period of 18 months. METHODS: From June 2016 to November 2019, 209 patients underwent aortic valve replacement with a biological prosthesis. Of these, 67 patients were included in the study based on the exclusion and inclusion criteria set before the study began. Their data were recorded during their hospital stay (preoperative, intraoperative, and early and late postoperative time). RESULTS: Fifty-four patients underwent isolated aortic valve replacement (group I) with a Perceval S prosthesis, and 13 patients had combined aortic valve replacement procedures and CABG procedures (group II). Patients were implanted with the following prosthesis sizes: S (N = 12), M (N = 18), L (N = 28), or XL (N = 9). The Perceval S valve successfully was implanted in 67 (91.8%) patients (in 6 patients, the preoperative transthoracic echocardiographic data did not coincide with intraoperative TEE and surgical measurement of the size of the annulus in the suture). Surgical approaches in patients were medial sternotomy (N = 48), mini sternotomy (N = 15), and thoracotomy through the second intercostal space to the right (N = 4). The mean clamping time of the aorta and CPB length for isolated cases was 54 and 82 minutes, respectively, and 96 and 120 minutes for combined procedures. Four (5.9%) patients died within 30 days. CONCLUSION: Early postoperative results showed that the Perceval S valve was safe. Further follow up is required to evaluate the long-term duration of patients with this bioprosthesis.

ABSTRACT

PURPOSE: To investigate the impact of lower urinary tract symptoms on health-related quality of life (QoL) in Serbian population considering socio-demographic characteristics, habits, and health status. MATERIALS AND METHODS: The study was conducted in the Primary Healthcare Center "Novi Beograd", Serbia. The study included 1424 male participants, aged 40 years and above. QoL was assessed by using the -36Item Short Form Health Survey (SF36-) questionnaire, while voiding and incontinence symptoms were measured using the International Continence Society Male Short Form (ICS male SF) questionnaire. RESULTS: Voiding and incontinence symptoms significantly correlate with all domains of QoL. Voiding and incontinence symptoms have a high influence on general health, social functioning, physical functioning and body pain. After adjusting for age and education, voiding and incontinence symptoms had a similar influence on QoL. In the multivariate model the influence of cardiovascular diseases and income on QoL was lower than voiding and incontinence symptoms.. CONCLUSION: Voiding and incontinence symptoms affect QoL domains differently. Incontinence symptoms have a greater impact on QoL than voiding symptoms.

ABSTRACT

INTRODUCTION: The objective of this study was to cross-culturally adapt and validate ICS male SF questionnaire to Serbian language. MATERIALS AND METHODS: This study included 91 male patients with lower urinary tract symptoms and 24 men with similar age and with confirmed absence of LUTS. ICS male SF questionnaire was translated from English to Serbian language and then back-translated to English. RESULTS: Internal consistency was high in both dimensions, voiding (Cronbach's alpha = 0.916) and incontinence (Cronbach's alpha = 0.763). Comparison of the average scores between patients and controls revealed significant differences in both dimensions: voiding (med = 8 versus med = 0; P < 0.001) and incontinence (med = 3 versus med = 0; P < 0.001). Interclass correlation revealed high testretest validity in both dimensions, voiding ICC = 0.992 (P < 0.001) and incontinece ICC = 0.989 (P < 0.001). Correlation analysis revealed high agreement between ICS male SF voiding dimension and IPSS questionnaire (ρ = 0.943; P < 0.001). CONCLUSION: The Serbian version of male ICS SF questionnaire showed acceptable reliability and validity. The ICS male SF questionnaire could be used in routine practice as an easy and comprehensive tool for assessment of LUTS.

ABSTRACT

INTRODUCTION: Delirium is a temporary mental disorder that frequently occurs among elderly hospitalized patients. Patients who undergo cardiac operations have an increased risk of postoperative delirium, which is associated with higher mortality and morbidity rates, a prolonged hospital stay, and reduced cognitive and functional recovery. PATIENTS AND METHODS: In our prospective study, we included 370 consecutive adult patients who underwent on-pump coronary artery surgery between January 1, 2011, and July 1, 2011. We selected 21 potential risk factors and divided them into preoperative, intraoperative, and postoperative groups. Delirium was diagnosed with the Confusion Assessment Method. RESULTS: Postoperative delirium was diagnosed in 74 patients (20%). Four predictive factors were associated with postoperative delirium: diabetes mellitus, cerebrovascular disease, peripheral vascular disease, and prolonged intubation (P < .05). CONCLUSION: Three of the four predictive factors significantly associated with delirium are preoperative. They are relatively easy to measure and can be used to identify patients at higher risk. Fast extubation of these patients and preventive interventions can be taken to prevent negative consequences of this postoperative complication.
