High incidence and significance of repercussions on patient health and healthcare system make postoperative cognitive dysfunction (POCD) a major problem following cardiac surgery. POCD frequency drops over time since surgery and its occurrence are related to different aspects of cognitive deterioration that markedly impair the patient quality of life. Therefore, a substantial number of papers have focused on this complex postoperative complication, however, with limited achievement in clarifying it.

Background: The pathogenesis of postoperative cognitive decline (POCD) is still poorly understood; however, the inflammatory response to surgical procedures seems likely to be involved. In addition, our recent randomized controlled trial showed that perioperative corticosteroid treatment may ameliorate early POCD after cardiac surgery. To assess the long-term effect of dexamethasone administration on cognitive function, we conducted a 4-year follow-up.

Platelet transfusions are commonly administered to treat bleeding in cardiac surgery. The aim of this study was to compare platelet (PLT) count and values of collagen adenosine diphosphate closure time (cADP-CT) measured by Platelet Function Analyzer (PFA) for prediction of PLT transfusion therapy following coronary bypass surgery. For this prospective observational study, 66 patients scheduled for coronary artery bypass grafting (CABG) who received early PLT transfusions (within 60 min after the operation) were enrolled.

The growing number of publications concerning postoperative cognitive decline (POCD) after cardiac surgery is indicative of the health-related and economic-related importance of this intriguing issue. Significantly, the reported POCD incidence over the years has remained steady due to various unresolved challenges regarding the examination of this multidisciplinary topic. In particular, a universally accepted POCD definition has not been established, and the pathogenesis is still vaguely understood.

BACKGROUND A recent study reported that patients with higher cortisol levels on the 1st postoperative morning after cardiac surgery exhibited an increased risk of early postoperative cognitive decline (POCD). Therefore, we conducted the current study to gain further insight into the stress response to a surgical procedure as a potential risk factor for early POCD after cardiac surgery. MATERIAL AND METHODS This prospective cohort study enrolled 125 patients undergoing elective cardiac surgery with or without cardiopulmonary bypass (CPB).

Background: Postoperative cognitive decline (POCD), a very common complication after cardiac surgery, is characterised by impairment of both memory function and intellectual ability as well as being associated with increased use of healthcare resources. The investigators focused on the role of the inflammatory response to a surgical procedure as a potential factor involved in the pathogenesis of POCD.

Objective: The use of prophylactic dexamethasone to attenuate the inflammatory response was hypothesised to reduce the risk of POCD.

Background And Purpose: Trimetazidine, known as a metabolic modulator, is an anti-anginal drug used for treatment of stable coronary artery disease (CAD). It is proposed to act via modulation of cardiac metabolism, shifting the mitochondrial substrate utilization towards carbohydrates, thus increasing the efficiency of ATP production. This mechanism was recently challenged; however, these studies used indirect approaches and animal models, which made their conclusions questionable.

End of life is an unfortunate but inevitable phase of the heart failure patients' journey. It is often preceded by a stage in the progression of heart failure defined as advanced heart failure, and characterised by poor quality of life and frequent hospitalisations. In clinical practice, the efficacy of treatments for advanced heart failure is often assessed by parameters such as clinical status, haemodynamics, neurohormonal status, and echo/MRI indices.

In cardiac surgery, postoperative low cardiac output has been shown to correlate with increased rates of organ failure and mortality. Catecholamines have been the standard therapy for many years, although they carry substantial risk for adverse cardiac and systemic effects, and have been reported to be associated with increased mortality. On the other hand, the calcium sensitiser and potassium channel opener levosimendan has been shown to improve cardiac function with no imbalance in oxygen consumption, and to have protective effects in other organs.

One of the fundamental rights of every human being is to enjoy "the highest attainable standard of health". Achieving better health requires no only adequate medical knowledge and technologies, laws and social measures in the field of health care, but also sufficient funding for fulfilling people's right to health. However, economic crisis has left every community with limited possibility of investing in health care and forced them to use the available resources more efficiently.

First-generation drug-eluting stents (DES) have been associated with impaired localized coronary vasomotion and delayed endothelialization. We aimed to compare coronary vasomotion after implantation of a newer-generation everolimus-eluting stent (EES), with a first-generation paclitaxel-eluting stent (PES). Coronary vasomotion was studied in 19 patients with EES and 13 with PES.

Introduction: Campylobacter is an important causative agent of intestinal infections in humans. Bacteremia is detected in less than 1% of patients, mainly in immunocompromised patients and in extreme age groups. Cellulitis is a relatively common manifestation of Campylobacter infection, but concomitant bacteremia is a rare event.

At the moment of signing the Stent for Life (SFL) Initiative on August 31st, 2009, it was shown that, in Serbia during 2008, 48% of patients with ST-elevation myocardial infarction (STEMI) did not receive any reperfusion and only 19% and 33% received primary percutaneous coronary intervention (p-PCI) or hospital thrombolysis, respectively. However, during 2009, there was a trend towards a substantial increase in p-PCI procedures. This was the result of the commitment of cardiologists, the contract signed by the Health Insurance Fund (HIF) for remuneration of catheterisation laboratory (cathlab) staff for each p-PCI procedure (2005), and the provision of new cathlabs by the Ministry of Health (MOH).

Anesthesiologists often work extended duty shifts that result in acute and chronic sleep loss and circadian disruption. Stress caused by sleep deprivation, together with excessive workload could contribute to acute increases in blood pressure (BP) and sympathetic nervous system activity. Non-dipping pattern of BP is considered an additional risk factor for cardiovascular events and target organ damage.
