retrospective study
Opis:: Introduction: Cerebral palsy (CP) is caused by damage to the motor control centers of the developing brain and can occur during pregnancy, during childbirth, or following birth. Purpose: To study the selected risk factors for spastic CP in a retrospective study involving children with CP. Materials and methods: The study population included 92 children with spastic CP. The analysis of data from the case records of both groups included the following: child’s age, gender, pregnancy order, birth order, type of birth, time of birth, Apgar scores, birth weight, epilepsy, and psychomotor development. Results: CP occurred more often in boys. A total of 27 children had congenital hemiplegia, 35 had diplegia, and 30 had spastic tetraplegia. The mean gestational age at birth for children with CP was 35.96 ± 4.2 weeks versus a mean of 39.2 ± 1.4 (p<0.001) for the control group. The mean number of pregnancies and deliveries for mothers of children with CP compared to the control group did not differ significantly. Vaginal births and cesarean sections in the group of children with CP and controls occurred in similar percentages. The birth weight of children with CP (2615.8 ± 935.1) was significantly lower than the birth weight among the control group (3343.2 ± 497) (p=0.04). Almost 40 percent of the children with CP were born to mothers who had preterm labours compared to only 5.2 percent of controls. A mean Apgar score for children with CP (5.9 ± 3.3) at 1 minute was significantly lower than that for children without CP (9.10 ± 1.5) (p<0.001). Of the children with CP, 20 percent had epilepsy; none of the children without CP had epilepsy; 22 percent had slight delays, 17 percent had moderate delays, and 12 percent had severe delays. Conclusions: Gender, prematurity, low birthweight, asphyxia and epilepsy were related to the development of CP.

Opis:: Dla eliminacji niepożądanych drgań kamery w sekwencji obrazów wybrano metodę korelacji fazowej, jako efektywną i dokładną metodę analizy w dziedzinie częstotliwości, bazująca na fourierowskim twierdzeniu o przesunięciu. Pomimo, że analizowanie ruchu nie jest w tej dziedzinie naturalnym sposobem, ma jednak pożądane cechy. Artykuł opisuje metodę oraz całą ścieżkę implementacji: od ewaluacji algorytmu w środowisku MATLAB, przez bitowo wierny model stałoprzecinkowy algorytmu, aż do jego sprzętowej realizacji na platformie FPGA.
A typical DIS algorithm consists of the below-mentioned stages: image preprocessing, shift estimation between subsequent frames, unwanted jitter estimation and jitter compensation. To eliminate the unintended motion (jitter) in the sequence of images, a phase correlation method was taken under consideration. It is a powerful and accurate method to determine the relative shift between two signals. Using this method, the whole image is divided into several sub-images, on which phase correlation based motion estimation is performed. These sub-images are used to determine local motion vectors, represented by a vertical and horizontal component. Then, with a simple statistical analysis, an overall camera shift is estimated. The overall frame-to-frame motion consists of two components: intended camera movement (smooth, with a slow, monotonic variations from frame to frame) and unwanted motion (rapid, non-monotonic variations). Thus, temporal filtering can be applied to evaluate an unwanted jitter. Finally, the current image is compensated (framed) due to the evaluated jitter. The paper describes the method itself, as well as the whole path of its implementation: from software MATLAB evaluation of the algorithm, through the bit-accurate model of the algorithm, to the FPGA implementation. Validation of the design was carried out using real image sequences.

Opis:: Introduction: Facebook is the most popular socialnetworking website in the world. It is estimated that it currently has more than 350 million users worldwide. Purpose; To assess the risk of addiction to Facebook the risk of addiction to Facebook among students of the Faculty of Health Sciences at the Medical University of Białystok in Poland. Materials and methods: This study included 440 student Facebook users. The original survey, the Satisfaction with Life Scale (SWLS) as well as a Self-Assessment Test were used (FAT). Results: Twenty-seven percent of the sample have had Facebook accounts for one to two years. Fortyfive percent of the respondents had 91 to 300 Facebook friends. Ninety-four percent of the respondents reported that they do not think about Facebook when they are disconnected from it. A similar number of students reported that it is possible for people to become addicted to Facebook. Forty-seven percent of the respondents were convinced that they would be able to recognize a Facebook addict. The average number of points scored on the FAT test was 16.2 ± 21.1 points; the average on the self-assessment was 44.7 ± 20.1 points; the average on SWLS scale was 15.3 ±5.24 points. Five percent of students demonstrated features of Facebook addiction as well as low selfesteem and life satisfaction. Conclusions: Problematic use of Facebook affected a small percentage of respondents who had low self-esteem and self were dissatisfied with their lives.

Opis:: The morphology, thermal and mechanical properties of polyamide 12 (PA12)/poly(vinylidene fluoride) (PVDF) blends were investigated. These polymers are engineering, semi-crystalline polymers which are reciprocally immiscible. Differential scanning calorimetry (DSC), dynamic mechanical thermal analysis (DMTA) and scanning electron microscopy (SEM) were used to characterize the polymeric materials. Mechanical properties were examined by static tensile test. The investigations demonstrate that blends with higher amount of PVDF, with the morphology of two co-continuous semicristalline phases, exhibit better mechanical properties. The blends with small content of PVDF and prepared by extrusion show the morphology of small separated domains of PVDF and full continuous PA phase. The morphology of these blends is different than the blends prepared by internal mixer and have better mechanical properties too. Thus they can be used in particular applications without a compatibilizing agent.

Opis:: Excitation energy transport between zwitterion and cationic form of rhodamine B in glycerol-ethanol mixture is studied. Concentration course of the quantum yield exhibits a rapid drop at intermediate concentrations, where no dimers are formed contrary to the results of measurements carried out for solutions with a trace amount of acid or base in which single ionic forms are adopted. To describe properly such concentration behavior of the quantum yield forward and reverse, nonradiative excitation energy transport between the forms is considered. This task is performed by comparing experimental data with Monte-Carlo simulations.

Opis:: Introduction: A sick person who trusts his or her physician feels safer and more easily complies with the physician’s recommendations. Purpose: To validate to validate a Greek-language version of the Trust in Physician Scale (TPS) for Greek patients. Materials and Methods: The validation of a Greek-language version of the TPS was performed with a group of 251 patients at Kavala Hospital in Kavala, Greece. Validation consisted of the translation and evaluation of the psychometric properties of the Greek TPS and its application among Greek-speaking patients. Results: The internal consistency of the Greek TPS was high (Cronbach’s alpha = 0.895). The highest mean scores were for the items “I trust my doctor very much, and I always try to follow his or her advice” (M = 3.63 ± 0.91), “If my doctor tells me that something is true, then it must be true” (M = 3.55 ± 0.89), “I trust my doctor’s judgment of my medical care” (M = 3.44 ± 0.86), and “My doctor is usually considerate of my needs and puts them first” (M= 3.41 ± 0.88). Conclusions: The Greek-language version of The Trust in Physician Scale fulfills all of the criteria of psychometric and functional validation with the original scale.

Opis:: Background. The aim of this study was to investigate the influence of selected factors such as place of residence, education, age, duration of hospitalization and pain intensity before and after hip replacement surgery on the level of acceptance of the illness, on the subjective assessment of the patient’s state of health during surgery and on the level of pain and the ability to manage and reduce pain. Material and methods. The study included 181 patients diagnosed with hip joint degeneration and qualified for total hip replacement hospitalized in the Regional Specialist Hospital in Biała Podlaska, Poland. The study was conducted by means of a diagnostic survey with the use of a set of questionnaires: Acceptance of Illness Scale – AIS, WOMAC Scale, SF-36 Questionnaire, BPCQ Questionnaire. Results. More than half of the respondents (55.2%) were highly accepting of their condition. The level of acceptance was influenced by the place of residence, education, age, the intensity of pain after surgery and functional limitation. The overall assessment of the quality of life in the physical domain was – 62.9 points, with the worst scores for physical functioning and general health. Analysis with the WOMAC questionnaire showed that the majority of the subjects scored below 50 points on the functional limitation scale. All factors, except the level of pain before surgery, influenced the degree of functional limitation. Conclusions. Age, place of residence and education provided opportunities for pain control and the ability to reduce pain was perceived by those with longer hospital stays. Participants from cities had the highest quality of life. Education influenced the quality of life, which decreased with age and higher pain intensity. The better the quality of life, the higher the level of acceptance of illness, and vice versa.
Wprowadzenie. Celem niniejszej pracy było zbadanie wpływu wybranych czynników ta- kich jak: miejsce zamieszkania, wykształcenie, wiek, czas hospitalizacji oraz nasilenie bólu przed i po zabiegu operacyjnym protezoplastyki biodra na poziom akceptacji choroby, na su- biektywną ocenę stanu zdrowia operowanego pacjenta oraz na poziom bólowy i umiejętność panowania nad bólem i jego obniżeniem. Materiał i metody. Badaniem objętych zostało 181 pacjentów z rozpoznaniem zwyrodnienia stawu biodrowego i zakwalifikowanych do zabie- gu operacyjnego całkowitej alloplastyki biodra hospitalizowanych w Wojewódzkim Szpitalu Specjalistycznym w Białej Podlaskiej. Badanie przeprowadzono metodą sondażu diagno- stycznego z wykorzystaniem zestawu kwestionariuszy: Skali Akceptacji Choroby – AIS, Skali WOMAC, Kwestionariusza SF-36, Kwestionariusza BPCQ. Wyniki. Stwierdzono, że ponad połowa badanych (55,2%) w wysokim stopniu akceptowała swoje schorzenie. Na poziom akceptacji miały wpływ: miejsce zamieszkania, wykształcenie, wiek, natężenie bólu po zabiegu oraz ograniczenie sprawności funkcjonalnej. Ogólna ocena jakości życia w dziedzinie fizycznej wynosiła – 62,9 pkt., przy czym najgorzej wypadła ocena funkcjonowania fizycznego oraz zdrowia ogólnego. Analiza za pomocą kwestionariusza WOMAC wykazała, że większość badanych, w pomiarze stopnia ograniczenia sprawności funkcjonalnej, uzyskała poniżej 50 pkt. Wszystkie czynniki, poza poziomem bólu przed zabiegiem, wpływały na stopień ograniczenia sprawności. Wnioski. Wiek, miejsce zamieszkania oraz wykształcenie dały możliwości panowania nad bólem, a o możliwości jego zmniejszenia wiedziały osoby dłużej hospitalizowane. Najwyższą jakością życia charakteryzowały się osoby z dużych miast. Wykształcenie wpłynęło na jakość życia, która wraz z wiekiem i wyższym natężeniem bólu spadała. Im lepsza jakość życia, tym wyższy poziom akceptacji choroby i odwrotnie.

Opis:: Introduction: Health is one of the most important and cherished values in the elderly. It has been estimated that among people over 65 years old 80% of people suffer from at least one physical illness. Purpose: To identify the opinions of the respondents on the most common health problems of elderly over 60. Materials and methods: The study was conducted between January 2013 and November 2014 in three study groups: Polish, Belarusian and Greek students. A total of 600 (200 for each group) respondents were tested with the questionnaire created by authors. Results: Respondents indicated that the most characteristic physical features of elderly people are wrinkles (68.7%, n = 412), gray hair (54.3%, n = 326) while cardiovascular diseases are the most common health problem (76.3%, n = 458). The most significant factor in delaying the aging process was active lifestyle (85.3%, n = 512). Conclusions: There is a need for increased education in geriatrics and care of the elderly among students of health sciences, who in the future will be entered in the geriatric therapeutic teams. The perception of health problems of the elderly were different depending on the country of origin of the respondents. This may indicate that the students don’t know the basic diseases and ailments in this age group (for example geriatric giants).

Opis:: Introduction: Atrial fibrillation (AF) is one of the most frequent arrhythmias. In Poland, there is a risk of developing AF in about 400,000 people. Atrial fibrillation occurs most frequently as a result of disorders of physiological automatism and afterdepolarization and triggered activity. The treatment strategy of AF is based on pharmacological treatment and procedures such as ablation or cardioversion. The quality of life as defined by the WHO is an individual perception of one's well-being. On the other hand, the assessment of the quality of life in illness is modified regarding health problems. Purpose: The main goal of the study was to get to know the quality of life of people with atrial fibrillation. Materials and methods: The research was carried out using a diagnostic survey, based on a survey among 100 patients diagnosed with AF. The place of the research was the Regional Specialist Hospital in Biała Podlaska, in the Emergency Department. Results: Increased morbidity was observed among women and people over the age of 60. The majority of patients with AF declared the quality of life at the medium level. The respondents most often followed medical recommendations. The majority of respondents did not follow healthy lifestyle rules, because as many as 68% of respondents did not do any physical activity and a significant part of the respondents smoked cigarettes and had an inflated BMI. Conclusion: AF affects the quality life by causing sadness, irritation and insomnia.

Opis:: Purpose: To analyse knowledge of patients in the Interventional Cardiology Department in the field of theory of the disease entity, i.e. myocardial infarction and factors predisposing to its occurrence. Materials and methods: The study was carried out at the Interventional Cardiology Department of the Regional Specialist Hospital in BiałaPodlaska between 3.11.2017 and 20.12.2017. Sixty respondents were included, 62% women and 38% men. The largest group were patients between 46 and 60 years of age. The work involved an anonymous questionnaire, which contained 28 questions, including two open ones. Patients participated in the study were informed that the study was voluntary and the questionnaire was anonymous. Results: According to the respondents, the main cause of myocardial infarction is atherosclerosis (43.4%). The respondents indicate that cardiovascular diseases (including myocardial infarction) which are on the third place in Poland, right after cancer and injuries, cause death (63.3%). As the main factor that influences the occurrence of myocardial infarction is overweight and obesity (79.8%). More than half of the respondents assess their knowledge of myocardial infarction on average, while 18.3 % said that they have very good knowledge. Conclusions: Patients with myocardial infarction have quite a good knowledge about the risk factors for this disease. A large group of respondents tries to counteract the risk factors for myocardial infarction. A small part of the respondents undergoes regular blood tests (blood glucose level, total cholesterol and its fractions, measurement of blood pressure).

Materials and Methods: The validation of a Polish-language version of Anderson and Dedrick’s TPS was performed with a group of 849 patients. Validation consisted of the translation and evaluation of the psychometric properties of the Polish TPS and its application among Polish-speaking patients. We also explored the TPS with the patient’s sex, age, education, income, marital status, and number of physician visits. Results: The internal consistency of the Polish TPS was high (Cronbach’s alpha = .891). In our study, the TPS is positively associated with age, education, income, marital status, and number of physician visits. Also, we have found that the TPS is negatively associated with sex and place of residence. Conclusions: The Polish-language scale fulfills all the criteria of psychometric and functional validation with the original version of the Trust in Physician Scale.
