TBE in Lithuania

The first case of tick-borne encephalitis (TBE) in Lithuania, diagnosed by clinical and epidemiologic criteria only, was reported in 1953. A forest worker became ill with the disease in April after a tick bite, had a typical clinical presentation with shoulder girdle muscle paralysis and bulbar syndrome, and died after 12 days from the start of clinical symptoms. Autopsy data were compatible with viral encephalitis.1 Serological diagnosis of TBE in Lithuania was started in 1970.2

Skeletal muscle status, autonomic balance and short-term results of cardiac surgery

Funding Acknowledgements Type of funding sources: Public hospital(s). Main funding source(s): Research Institute for Complex Issues of Cardiovascular Diseases The aim - investigate the association of the lower extremities skeletal muscle state, status autonomic nervous system (ANS) and short-term results of the cardiac operations. Design Study included 64 patients, who underwent planned cardiac surgery. All subjects before surgery performed a routine laboratory and instrumental examinations, six-minute walk test (6MWT), and static-dynamic tests on the training device. ANS was carried out, using ORTOexpert software. Were formed 2 groups – with the combined endpoint CEP (n = 9) and without CEP (n = 55). CEP included: perioperative development stroke, myocardial infarction, persistent arrhythmias and heart block, multiple organ dysfunction syndrome, death. Results Not found difference between the groups in gender, age, in main clinical data and laboratory tests indicators, and in endurance of the skeletal muscles or the 6MWT. In the CEP group, strength of skeletal muscles of the upper and lower extremities was lower, initially more pronounced sympathetic activation and larger values of the power of the frequency spectrum (TF). Stress index (IS) was lower in the CEP group, but after transitioning orthostatic position it surpassed the number without CEP. One-factor logistic regression analysis established factors associated with the development of CEP - poor muscle status, peripheral atherosclerosis; high EuroSCORE, cardiopulmonary bypass duration (CBD) and ANS disbalance. Multivariate regression analysis to establish the relationship of poor skeletal muscle status, pronounced sympathicotonia and a high incidence of postoperative complications.
