APPLICATION OF THERMOGRAPHY TO ANALYZE THE EFFECTIVENESS OF ERGOMETER TRAINING

The work determines the degree of thermographic suitability of the method of temperature measurement in people exercising on a rowing ergometer. Thermography is gaining popularity in medical diagnostics by measuring the body temperature. Its main advantages are non-invasive, safe and comfortable for patients. It is widely used in the prevention of breast cancer and treatment of osteoarticular injuries. The basis for the use of thermography in medicine is the phenomenon of thermoregulation of living organisms and the emissive property of the skin, which is similar in value to a perfectly black body.To achieve the set goal, 10 people were trained on the rowing ergometer. During the two series of measurements (before and immediately after), the focus was on two areas of the subjects' body: upper limbs and abdomen.The thermographs obtained were analyzed taking into account the physical and physiological parameters of the players and their experience. The conclusions from them seemed to answer the thesis that the thermographic method is suitable for supporting players in planning and improving their training. It has also been shown that training on a rowing ergometer involves many muscle parties in which an increase in the released metabolic heat takes place

Integrated Computing, Communication, and Distributed Control of Deregulated Electric Power Systems

Restructuring of the electricity market has affected all aspects of the power industry from generation to transmission, distribution, and consumption. Transmission circuits, in particular, are stressed often exceeding their stability limits because of the difficulty in building new transmission lines due to environmental concerns and financial risk. Deregulation has resulted in the need for tighter control strategies to maintain reliability even in the event of considerable structural changes, such as loss of a large generating unit or a transmission line, and changes in loading conditions due to the continuously varying power consumption. Our research efforts under the DOE EPSCoR Grant focused on Integrated Computing, Communication and Distributed Control of Deregulated Electric Power Systems. This research is applicable to operating and controlling modern electric energy systems. The controls developed by APERC provide for a more efficient, economical, reliable, and secure operation of these systems. Under this program, we developed distributed control algorithms suitable for large-scale geographically dispersed power systems and also economic tools to evaluate their effectiveness and impact on power markets. Progress was made in the development of distributed intelligent control agents for reliable and automated operation of integrated electric power systems. The methodologies employed combine information technology, control and communication, agent technology, and power systems engineering in the development of intelligent control agents for reliable and automated operation of integrated electric power systems. In the event of scheduled load changes or unforeseen disturbances, the power system is expected to minimize the effects and costs of disturbances and to maintain critical infrastructure operational

Factors which influence mortality in patients with Infective Endocarditis

Department of Internal Medicine, Cardiology, Nicolae Testemitanu State University of Medicine and Pharmacy, Chisinau, Republic of Moldova, The 8th International Medical Congress for Students and Young Doctors, September 24-26, 2020Introduction. Infective Endocarditis (IE) is a severe rising incidence pathology with high mortality. The incidence of IE is 3-10 cases per 100,000 people/year. The most common complications in IE that lead to death are: Congestive Heart Failure (CHF) - 33.4%, stroke 17.9%, and embolic events - 34.3%. Early and adequate initiation of antibiotic therapy significantly reduces mortality by 25-50%, and the frequency of embolic events in 13 patients out of 1,000 in the first week of treatment and 1.2 to 1,000 after two weeks of appropriate treatment, and early surgery can improve the evolution of EI. with an estimated overall survival of 74.8 ± 4.1% at 10 years. Despite improvements in the diagnosis, treatment and management of EI, the pathology remains associated with severe complications and high mortality. Aim of the study. The purpose of the research is: to evaluate the factors which influence mortality in patients with Infective Endocarditis in Republic of Moldova. Materials and methods. There were retrospectively evaluated 161 patients with clinically definitive diagnosis of IE according the Duke and J. Li criteria, admitted between 2013 - 2019 at the Institute of Cardiology and Municipal Hospital „Holy Trinity”, Chisinau, Republic of Moldova. Patients were devided in two groups deaths (D) 31 (19.3%) and alive (A) 130 (80.7%). The following characteristics were studied: age, gender, type of IE, injection drug use, Diabetes Mellitus, haemoculture, presence of Staphylococcus aureus, vegetations and their features, C-reactive protein, ASL-O, left ventricular ejection fraction and other complications. Data collection was based on the review of available medical charts, reports from the echocardiography laboratory, and accessible valve surgery reports during the study period. Data analysis was performed with statistical software Epi Info (CDC, Atlanta, ver. 7.2.2.16). Odds Ratio (OR) is used to estimate the strength of the association between risk factors, and outcomes of mortality, so OR> 1 means that the risk of the outcome is increased by the exposure. Variables were compared using two-tailed t-test and statistical significance was defined by p ≤ 0.05. Results. The most affected age in both groups was 45-64 years, 51.6% for group D, and 56.2.4% for group A, with a mean age of 57.7 ± 12.3 years for group D and 51.3 ± 13.7 years for group A. Nevertheless, the cases of death exceeded in group >65 years 29% vs 16.9% (OR 2.0; 95% CI, 0.82-4-94; p = 0.124). In both groups prevailed men with 64.5% and respectively 76.2%, but it is observed an increase of prevalence to 35.5% for women in group D (OR 1.8; 95% CI, 0.76-4.06; p = 0.184). Acute onset IE was more frequently in group D 41.9% vs 37.7 in group A (OR 1.2; 95% CI, 0.54-2.65; p = 0.890), as well prosthetic valve IE (PVIE) 16.1% vs 12.3% (OR 1.4; 95% CI, 0.46-4.07; p = 0.570). Diabetes mellitus predominated in group D 29% vs 12.3% in group A (OR 4.0; 95% CI, 1.51-10.7; p <0.05). Blood culture was positive in 51.6% of patients in group D and 23.8% in group A (OR 3.4; 95% CI, 1.51-7.67; p <0.05), and prevailing in both groups Staphylococcus aureus (OR 4.4; 95% CI, 1.47-13.42; p <0.05) and Staphylococcus epidermidis (OR 4.7; 95% CI, 1.09-19.83; p <0.05) as pathogens. We observed in both groups vegetations in more then 70% of patients, but in the group D, 19.4% vs 14.6% were affected more valves, with predominating in group D middle size vegetations 32.3% vs. 23.1% (OR 1.6; 95% CI, 0.67-3.73; p = 0.287) and big size 12.9% vs 6.9% (OR 1.9; 95% CI, 0.57-6.95; p = 0.272). The most affected valves in group D was the tricuspid one 12.9% vs 11.5% (OR 1.1; 95% CI, 0.35-3.69; p = 0.832). Group D had an increased rate of CHF 61.3% vs 53.8% NYHA class III (OR 1.4; 95% CI, 0.61- 3.02; p = 0.453) and class IV 25.8% vs 10.8% (OR 2.9; 95% CI, 1.08-7.66; p <0.05). Embolic events occurred in 61.3% in group D and in 14.6% of patients in alive group (OR 9.3; 95% CI, 3.87-22.1; p <0.001). Also, the renal damage was higher in group D, Acute Kidney Failure (AKF) 12.9% vs 3.1% (OR 4.7; 95% CI, 1.09-19.83; p <0.05), Chronic Kidney Disease (CKD) 38.7% vs 9.2% (OR 6.2; 95% CI, 2.44- 15.8; p <0.001). Septic shock (SS) was more frequently in group D 29% vs. 4.6% (OR 8.5; 95% CI, 2.74-26.1; p <0.001). Conclusions. According to Odds Ratio we found in our study 36 factors that can influence mortality in patients with infective endocarditis, nevertheless only 17 of them proved to have statistical significance difference. Therefore, these factors in our study were: Diabetes Mellitus (OR 4.0; 95% CI, 1.51-10.7; p < 0.05); positive blood culture (OR 3.4; 95% CI, 1.51-7.67; p < 0.05); Staphylococcus aureus (OR 4.4; 95% CI, 1.47-13.42; p < 0.05); Staphylococcus epidermidis (OR 4.7; 95% CI, 1.09-19.83; p < 0.05); Congestive Heart Failure class IV NYHA (OR 2.9; 95% CI, 1.08-7.66; p < 0.05); embolic events (OR 9.3; 95% CI, 3.87-22.1; p < 0.001) with the following clinically most important pulmonary embolism (OR 6.2; 95% CI, 2.17-17.9; p < 0.001), stroke (OR 3.7; 95% CI, 1.17-11.5; p < 0.05), Acute Kidney Failure (OR 4.7; 95% CI, 1.09-19.83; p < 0.05), Chronic Kidney Disease (OR 6.2; 95% CI, 2.44-15.8; p < 0.001) and Septic shock (OR 8.5; 95% CI, 2.74-26.1; p < 0.001)

Disciplina de Pneumologie și alergologie, Departamentul Medicină internă, USMF ”Nicolae Testemițanu”, Chișinău, Republica Moldova, IMSP AMT Botanica CMF nr 2ntroducere Odată cu pandemia de Covid-19 și instituirea măsurilor de carantină și izolare, importanța sensibilizării la alergene de interior a căpătat o nouă dimensiune. Expunerea îndelungată la concentrații crescute de alergeni pot agrava și mai mult simptomele respiratorii la pacienții alergici. Alergenele animalelor de companie și acarienii sunt cele mai frecvente alergene perene. Alergenele animalelor sunt prezente în mătreața, salivă, urină și lichid seminal (masculi). Se atașează de blană și se răspândesc în încăpere. Pisicile par să inducă sensibilizare mult mai frecvent decât câinii. Alergenii pisicii persistă 1,5 - 2 ani după excluderea pisicii din casă. Existenţa unor rase hipoalergenice este controversată, nefiind identificate alergene specifice unor anumite rase de câini sau pisici. Scopul studiului Analiza particularităților de sensibilizare la alergene de interior (acarieni, fungi, animale) a pacienților cu rinită alergică și astm în perioada pandemiei de Covid-19. Material și metode În studiu au fost incluși 130 de pacienți cu rinită alergică și astm, consultați ambulatoriu în Clinica de Pneumologie și alergologie USMF Nicolae Testemițanu în 2020. Au fost analizate sensibilizările la alergene de interior (acarieni, fungi, animale) utilizând testul alergologic multiplex ALEX (extracte alergenice și componente moleculare). Concluzie Sensibilizarea la alergene de interior este importantă în toate grupele de vârstă. Pandemia de Covid-19 și măsurile de carantină au expus pacienții la concentrații crescute de alergeni. Expunerea îndelungată poate duce la agravarea semnificativă a simptomelor de alergii

Discipline of Pneumology and Allergology, Nicolae Testemitanu SUMPh, Territorial Medical Association Botanica, ChisinauBackground. With the outbreak of the Covid-19 pandemic and lockdown, the importance of sensitization to indoor allergens has taken on a new dimension. Prolonged exposure to high concentrations of allergens may further aggravate respiratory symptoms in allergic patients. Objective of the study. Analysis of the particularities of sensitization to indoor allergens (mites, molds, pets) of patients with allergic rhinitis and asthma during the Covid-19 pandemic. Material and Methods. The study included 130 patients with allergic rhinitis and asthma, consulted as an outpatients at the Pneumology and Allergology Department in 2020. Sensitizations to indoor allergens (mites, molds, pets) were analyzed using the multiplex allergology test ALEX (allergen extracts and molecular components). Results. The mean age was 32 years, female 52.3%. The pediatric population 21.5%. Half of the patients included in the study (53.1%) were sensitized to pets (dog 20%, cat 33.1%), 39.2% had sensitization to mites and 23.1% to molds. Children were most frequently sensitized to molds - 57.1% of cases (50% Alt a 1) and cats 53.6% cases (80% Fel d 1). In adults cat sensitisation was in 27.4% of cases. In all patients prevail sensitization to Fel d 1, the major allergic molecule of the cat. Dog sensitization was most common in patients aged 29-38 years - 32.5% (46.1% to Can f 1). Conclusion. Sensitization to indoor allergens is important in all age groups. The Covid-19 pandemic and lockdown exposed patients to high concentrations of indoor allergens. Prolonged exposure may lead to a significant worsening of allergy symptoms.Introducere.
