BACKGROUND: Burnout syndrome is a phenomenon that seems to be studied globally in relation to all types of populations. The staff in the system of correctional institutions in Bulgaria, however, is oddly left out of this tendency. There is no standardized model in Bulgaria that can be used to detect possible susceptibility to professional burnout. The methods available at present only register the irreversible changes that have already set in the functioning of the individual. V. Boyko's method for burnout assessment allows clinicians to use individual approach to patients and affords easy comparability of results with data from other psychodiagnostic instruments...

BACKGROUND: Inflammatory diseases of the heart (myocarditis, pericarditis) are commonly caused by viruses. Among the human cardiotropic viruses, parvovirus B19, Coxsackie B viruses, and adenoviruses play a leading role. AIM: The aim of the present study was to determine the presumptive causative role of parvovirus B19, Coxsackie B viruses, and adenoviruses in the development of myocarditis, pericarditis and dilated cardiomyopathy by demonstrating the presence of specific antiviral antibodies or viral DNA in patients' serum samples...

Adipose tissue is recognized as a rich source of proinflammatory mediators that may directly contribute to vascular injury, insulin resistance, and atherogenesis. Many studies have shown that adiponectin has antiatherogenic and anti-inflammatory properties. Adiponectin acts not only as a factor increasing insulin sensitivity, and the protective effect may result from its ability to suppress production of proinflammatory cytokines. It negatively regulates the expression of TNF-alpha and C-reactive protein (CRP) in adipose tissue; reduces expression of vascular and intracellular adhesion molecules (VCAM-1, ICAM-1), E-selectin, interleukin-8 (IL-8)...

BACKGROUND: Alcohol-induced cerebellar neurodegeneration is a neuroadaptation that is associated with chronic alcohol abuse. Conventional drugs have been largely unsatisfactory in preventing neurodegeneration. Yet, multimodal neuro-protective therapeutic agents have been hypothesised to have high therapeutic potential for the treatment of CNS conditions; there is yet a dilemma of how this would be achieved. Contrarily, medicinal botanicals are naturally multimodal in their mechanism of action...

Chronic heart failure (CHF) is a major health problem associated with increased mortality, despite modern treatment options. Central sleep apnea (CSA)/Cheyne-Stokes breathing (CSB) is a common and yet largely under-diagnosed co-morbidity, adding significantly to the poor prognosis in CHF because of a number of acute and chronic effects, including intermittent hypoxia, sympathetic overactivation, disturbed sleep architecture and impaired physical tolerance. It is characterized by repetitive periods of crescendo-decrescendo ventilatory pattern, alternating with central apneas and hypopneas...

Brucellosis is a zoonotic disease widely seen in endemic regions and that can lead to systemic involvement. The musculoskeletal system is frequently affected, and the disease can exhibit clinical involvements such as arthritis, spondylitis, spondylodiscitis, osteomyelitis, tenosynovitis and bursitis. Spondylitis and spondylodiscitis, common complications of brucellosis, predominantly affect the lumbar and thoracic vertebrae. Epidural abscess may occur as a rare complication of spondylitis. Spinal brucellosis and development of epidural abscess in the cervical region are rare...

Image-guided spinal surgery is becoming increasingly popular because it allows surgeons to achieve minimal invasiveness and maximum precision in the performed procedures. We present our initial experience with two cases operated on using O-arm-based spinal navigation at the Clinic of Neurosurgery in St George University Hospital, Plovdiv, Bulgaria. In the first case, we performed removal of extradural spinal tumor of the sixth thoracic vertebra and O-arm-navigated pedicle screw fixation. In the second case, we performed O-arm-navigated corpectomy of the fifth cervical vertebra and anterior spinal reconstruction and fusion with titanium expandable mesh and cervical plate in connection with degenerative narrowing of the cervical spinal canal that lead to clinically manifested myelopathy...

AIM: To assess the effect of the factor 'hepatic metastatic disease' on long-term outcomes in patients with colorectal cancer. MATERIALS AND METHODS: We analysed retrospectively 200 randomly selected patients. Forty-two of them were excluded from the study for different reasons so the study contingent was 158 patients over a period of 23 years. All were diagnosed and treated in the Lozenetz University Hospital, in the Department of General Surgery. 125 of the patients were diagnosed with colorectal cancer without distant metastases and 33 of the patients had liver metastases as a result of colorectal carcinoma...

Multiple sclerosis (MS) is a socially significant immune-mediated disease, characterized by demyelination, axonal transection and oligodendropathy in the central nervous system. Inflammatory demyelination and neurodegeneration lead to brain atrophy and cognitive deficit in up to 75% of the patients. Cognitive dysfunctions impact significantly patients' quality of life, independently from the course and phase of the disease. The relationship between pathological brain findings and cognitive impairment is a subject of intensive research...

BACKGROUND: Biomechanical stress and inflammatory biomarkers relate to global contractility dysfunction; however, adding these biomarkers into a risk model constructed on clinical data does not improve its prediction value in chronic heart failure (CHF). AIM: The aim of this study was to evaluate whether biomarkers predict declining of left ventricular global contractility function in diabetic patients with ischemia-induced CHF. PATIENTS AND METHODS: The study retrospectively evolved 54 diabetic patients who had systolic or diastolic ischemia-induced CHF that was defined as left-ventricular ejection fraction (LVEF) ≤45% or 46-55% respectively assessed by quantitative echocardiography and other conventional criteria according to current clinical guidelines...
