RESUMO

BACKGROUND: All the patients with suspected stroke are directed to whole-brain CT scan. The purpose of this scan is to look for early features of ischemia and to rule out alternative diagnoses than stroke. In case of ischemic stroke, CT diagnostics (including CT angiography) is used mainly to locate the occlusion and its size, while the Hounsfield Units (HU) values of the thrombus causing the stroke are usually overlooked on CT scan or considered not important. The aim of this study was to demonstrate that the HU value is relevant and can help in better treatment planning. PATIENTS AND METHODS: There were 25 patients included in the study, diagnosed with ischemic stroke in the middle cerebral artery (MCA) territory. In all patients, systemic thrombolysis was not successful and the mechanical recanalization was needed. The retrieved thrombi were also analyzed histologically for the determination of red blood cells (RBC) proportion. CT of the proximal MCA (M1) segment was analyzed for average HU value and its variability both in the occluded section and the symmetrical normal site. These CT parameters were then statistically studied for the possible correlations with different clinical, histological and procedure parameters using the Linear Regression and the Pearson correlation coefficient. RESULTS: Relevant positive correlations were found between average HU value of thrombus and outcome modified Rankin Scale (mRS), initial mRS, number of passes with thrombectomy device as well as RBC proportion. CONCLUSIONS: Results of the present study suggest that measured HU values in CT images of the cerebral thrombi may help in the assessment of thrombus compaction and therefore better treatment planning.

RESUMO

The study aims to estimate the cost-effectiveness of superabsorbent wound dressings compared to the standard-of-care (SoC) dressings mix for treatment of patients with moderate-to-highly exuding leg ulcers in the German healthcare settings. A model-based cost-effectiveness analysis was conducted from the German statutory health insurance perspective, following German specific and international recommendations of good research practice. An individual-level (microsimulation) state-transition model has been used with a cycle length of 1 week and time horizon of 6 months. Several comprehensive systematic reviews were conducted to inform all model inputs, including clinical parameters, efficacy, quality of life, resources utilisation, and cost inputs. In addition, primary data from two clinical trials were used. Based on this cost-effectiveness analysis, using superabsorbent wound dressings instead of the SoC dressings of patients with moderate-to-highly exuding leg ulcers in Germany can lead to an improved healing rate of 2.57% (benefit ratio 1.08), improved health-related quality of life of 0.152 quality-adjusted life weeks, and total direct cost savings of €771 per patient in 6 months. Robustness of results was confirmed in sensitivity and scenario analyses.

RESUMO

Although absolute jump heights should be considered an important factor in judging the performance requirements of volleyball players, limited data is available on age-appropriate categories. The purpose of this study is to determine the differences in specific anthropometric characteristics and jumping performance variables in under-19 female volleyball players in relation to playing position and performance level. The sample of subjects consisted of 354 players who prepared for the U19 Women's Volleyball European Championship 2020 (17.4 ± 0.8 years, 1.81 ± 0.07 m, 67.5 ± 7.1 kg). Playing positions analyzed were setters (n = 55), opposites (n = 37), middle blockers (n = 82), outside hitters (n = 137), and liberos (n = 43). The results showed player position differences in every performance level group in variables of body height, spike, and block jump. Observed differences are a consequence of highly specific tasks of different positions in the composition of the team. Players of different performance levels are significantly different, with athletes of higher-ranked teams achieving better results. The acquired data could be useful for the selection and profiling of young volleyball players.

RESUMO

This study aimed to consolidate the body height, body weight, BMI, and nutrition status data of the overall young male population from the Municipality of Berane in order to assess the trajectories of those variables from 1979 to 1987. The sample of respondents included 8740 adolescents who were divided into nine groups according to their age. The sample of variables included body height, body weight, body mass index, and nutrition status, which were presented based on a long-established BMI categorization (underweight, normal weight, pre-obese, and obese). The descriptive statistics are expressed as the mean and standard deviation for each variable; the analysis of nutrition status was calculated based on BMI, while LSD post hoc testing with ANOVA was employed to investigate differences between the means. The results indicate that a secular trend is visible regarding body height and body weight, while no trend is visible for the BMI and nutrition status. This study's contribution is that it provides insight into more recently published data for the studied period and in this municipality, which can significantly aid in following the secular trend throughout Montenegro.

RESUMO

Strength training can improve myriad health parameters in elderly cohorts. Although potentially more appropriate for the elderly, low-load resistance training protocols have been less investigated. We aimed to examine the effects of 12 weeks of chair-based, low-load resistance training with elastic band (EBT) on functional fitness and metabolic biomarkers in older women. One hundred sixty-eight women were allocated randomly to an elastic band resistance training (EBT, n = 86, 75.7 ± 8.9 years, 71.3 ± 12.2 kg) or a control group (CON, n = 82, 74.5 ± 8.2years, 70.6 ± 12.0 kg). RT protocol consisted of periodized chair-based, low-load whole-body resistance exercises (2 sets, 12-15 repetitions, 40-60% of one repetition maximum-1RM) using an elastic band, twice weekly for 12 weeks. The resistance training program was generally designed to maintain internal load over time, provided with increasing intensity using various elastic bands (Thera-Band). Functional fitness (30-s Chair Stand,30-s Arm Curl, 2-min Step Test, Chair Sit-and-Reach, Back Scratch, 8-Foot Up-and-Go, Handgrip Strength) and metabolic markers (Fasting blood glucose, triglycerides, total cholesterol, high (HDL) and low (LDL) density lipoprotein) were measured before and after the training period. To detect pre/post intervention changes and between group- differences 2x2 repeated measures ANOVA was applied. Significant improvements over time for all fitness variables for EBT comparing to CON were obtained (F = 12.78, p < 0.05 for 30-s Chair Stand; F = 14.04, p < 0.05 for 30-s Arm Curl; F = 5.18, p < 0.05 for 2-min Step Test; F = 10.90, p < 0.05 for Chair Sit-and-Reach; F = 16.57, p < 0.05 for Back Scratch; F = 11.79, p < 0.05 for 8-foot Up-and-Go; and F = 29.25, p < 0.05 for Handgrip Strength). In addition, significant improvements over time for all but one (triglycerides) biomarkers for EBT comparing to CON were obtained (F = 7.30, p < 0.05 for blood sugar levels; F = 13.36, p < 0.05 for total cholesterol; F = 8.61, p < 0.05 for HDL; and F = 11.53, p < 0.05 for LDL). Furthermore, the participants' adherence to training sessions of over 90% was reported. In conclusion, 12 weeks of EBT is safe and beneficial for improving health-related fitness and metabolic biomarkers in older women and seems to be viable model to ensure a high training adherence rate.

RESUMO

(1) Background: Regular physical activity (PA) plays an important role during early childhood physical and psychological development. This study investigates the effects of a 9-month PA intervention on physiological characteristics and motor and cognitive skills in preschool children. (2) Methods: Preschool children (n = 132; age 4 to 7 years) attending regular preschool programs were nonrandomly assigned to PA intervention (n = 66; 60 min sessions twice per week) or a control group (n = 66; no additional organized PA program) for 9 months. Exercise training for the intervention group included various sports games, outdoor activities, martial arts, yoga, and dance. Anthropometry, motor skills (7 tests), and cognitive skills (Raven's Colored Progressive Matrices and Cognitive Assessment System) were assessed before and after an intervention period in both groups. Data were analyzed using repeated-measures ANOVA. (3) Results: Body weight significantly increased in both groups over time. Compared to the changes observed in the control group, the intervention group significantly increased in chest circumference (p = 0.022). In contrast, the control group demonstrated an increase in waist circumference (p = 0.001), while these measures in the intervention group remained stable. Participants in the intervention group improved running speed (p = 0.016) and standing broad jump (p = 0.000). The flexibility level was maintained in the intervention group, while a significant decrease was observed in the control group (p = 0.010). Children from the intervention group demonstrated progress in the bent-arm hang test (p = 0.001), unlike the control group subjects. Varied improvements in cognitive skills were observed for different variables in both intervention and control groups, with no robust evidence for PA-intervention-related improvements. (4) Conclusions: Preschool children's participation in a preschool PA intervention improves their motor skills.

RESUMO

OBJECTIVE: The aim of this study was to examine subjective sensitivity to noise of the citizens of Nis and its impact on their non-auditory health effects. METHODS: This study was designed as a cross-sectional questionnaire survey among 908 adult residents of Nis, Serbia, of whom 387 were men (42.6%) and 521 women (57.4%). Streets with day Leq ≥ 55 dB(A) and night Leq ≥ 45 dB(A) were regarded as noisy and those with day Leq ≤ 55 dB(A) and night Leq ≤ 45 dB(A) were regarded as quiet, in accordance with WHO recommendations. Noise sensitivity was measured with the Weinstein's Noise Sensitivity Scale. Logistic regression analysis was used to assess the impact of noise sensitivity on non-auditory health effects. RESULTS: The study showed that the values of the Weinstein's Noise Sensitivity Scale were significantly higher for those surveyed in the noisy zone. Multiple regression analysis revealed a significant impact of noise sensitivity on night-sleep duration (p = 0.04), subjective assessment of sleep quality (p < 0.01) and daily rest disruption (p < 0.001). CONCLUSION: Based on the study results, it can be confirmed that noise sensitivity has an important role in causing non-auditory health effects among adults.

RESUMO

Background and objectives: Persistent infection with carcinogenic human papillomavirus (HPV) is the leading cause of cervical cancer. The study explored students' knowledge about cervical cancer and awareness of human papillomavirus and the HPV vaccine. Materials and Methods: A questionnaire-based survey was carried out among 1616 first-year female college students at the University of Nis. It examined socio-demographic characteristics, measured the score of knowledge about cervical cancer, assessed awareness regarding HPV and the HPV vaccine and inquired about the source of information about cervical cancer and HPV. Results: The average cervical cancer knowledge score was 16.35 ± 7.92 (min 0, max 30), with medical professional education, parents' education level, place of residence and relationship status having significant effects on the score. The awareness about HPV and the HPV vaccine was low, with only 14.2% of students having heard about both HPV and its vaccine. The most commonly reported sources of information were the media, while the most competent one was organized health education. Conclusions: Health promotion campaigns and educational programs are necessary in order to reduce cervical cancer burden and should be directed particularly towards those who have demonstrated low cervical cancer knowledge and low awareness regarding HPV and its vaccine.

RESUMO

Background Acute bilateral internal carotid artery (ICA) and/or middle cerebral artery (MCA) occlusion is extremely rare and associated with poor clinical outcomes. There are only a few reports in the literature about mechanical thrombectomy being performed for acute bilateral occlusions. The treatment strategies and prognoses (clinical outcomes) are therefore unclear. Methods A systematic review of the literature was performed through several electronic databases with the following search terms: acute bilateral stroke, mechanical recanalization and thrombectomy. Results In the literature, we identified five reports of six patients with bilateral ICA and/or MCA occlusion treated with mechanical recanalization. Additionally, we report our experience with a subsequent contralateral large brain artery occlusion during intravenous thrombolytic therapy, where the outcome after mechanical thrombectomy was not dependent on the time from stroke onset but rather on the capacity of collateral circulation exclusively. Conclusions Acute bilateral cerebral (ICA and/or MCA) occlusion leads to sudden severe neurological deficits (comas) with unpredicted prognoses, even when mechanical recanalization is available. As the collateral capacity seems to be more important than the absolute time to flow restoration in determining the outcomes, simultaneous thrombectomy by itself probably does not lead to improved functional outcomes.

RESUMO

OBJECTIVE: To observe the effect of rapid weight loss (RWL) methods over 3 days on muscle damage in judokas. METHODS: Eighteen judokas participated in this crossover study, meaning that judo athletes were subjected to exercise-only phase (4 days) and RWL phase (3 days). Subjects were tested for myoglobin, creatine kinase, aldolase, hemoglobin, and hematocrit values on seven consecutive days. These biomarkers served as indicators of acute muscle damage. RESULTS: During the exercise-only phase, no significant changes were observed. Myoglobin (Mb) (p < 0.001), creatine kinase (CK) (p < 0.001) and aldolase (ALD) (p < 0.001) significantly increased only during the RWL phase, as well as hemoglobin (Hb) (p < 0.001) and hematocrit (Hct) (p < 0.005) values. It was detected that peak values for muscle damage biomarkers were reached on the sixth day, while Hct and Hb values were the highest on the seventh day of the study. CONCLUSION: Our study showed significant muscle damage induced by RWL. The prevalence of RWL use by judokas is high but firm scientific evidence is lacking in the evaluation of the current practice of it. Therefore, further knowledge must be gained to evaluate the effectiveness of RWL on performance and its impact on judokas' wellbeing.

RESUMO

Background Recent advances in MRI technology makes it increasingly more competitive to CT also in the field of interventions. Multi-parametric MRI offers a significant amount of data relevant for characterization of human cerebral thrombi. Patients and methods Cerebral thrombi of 17 patients diagnosed with acute stroke were acquired by mechanical thrombectomy. The thrombi were subsequently scanned using a high spatial-resolution 3D T1-weighted MRI to obtain morphological characteristics of the thrombi and also by apparent diffusion coefficient (ADC) and transversal nuclear magnetic resonance (NMR) relaxation time (T2) mapping. The MRI results were analysed for possible correlations between thrombectomy procedure parameters (recanalization time and number of passes) and MR-measurable parameters (sample-mean ADC and T2, within-sample coefficient of variation of ADC and T2, and thrombus length). Results Both MRI mapping techniques enabled a good discrimination among thrombi regions of different water mobility and compaction. Within-sample coefficient of variation of ADC was found most sensitive for discrimination between the thrombi where thrombectomy procedure was performed in a single pass and those where is was performed in two or more passes (p = 0.03). Interestingly, negative correlation was found between the recanalization time and thrombus length (ρ = -0.22). Conclusions Preliminary results of presented study shows that pretreatment MRI assessment of thrombi in stroke patients could potentially ease stroke treatment planning. In this study it is shown that within-sample coefficient of variation of ADC could serve for prediction of possible complications during thrombectomy procedures.

RESUMO

BACKGROUND: The vein of Galen aneurismal malformations (VGAM) are rare arteriovenous malformations of the embryonic choroid plexus. They represent about 30% of paediatric neurovascular disorders and show diverse characteristics. The VGAM is constituted by a midline dilated venous structure that receives blood from abnormal macroscopic or microscopic arteriovenous shunting vessels. Two types of VGAM exist, the choroidal and the mural. The treatment represents a challenge with the therapeutic objective to preserve the normal brain development without creating new neurological deficits. CASE SUMMARY: We present three cases of VGAM in the early postnatal period and their treatment. All patents were treated with the endovascular technique, which was successful. According to our experience, the endovascular technique is a safe and efficient mode of VGAM treatment. CONCLUSION: The objective of treatment aims to child's normal neurological development. A proper selection of patients and a thorough diagnostic workup is of vital importance. When the endovascular treatment is performed, the primary aim is not a complete VGAM exclusion at one time, which could produce a sudden reversal of blood flow with consequent venous infarction and ischemia. The aim is therefore to occlude as much of the VGAM as needed to relieve the congestive cardiac failure, to gain time and to create the conditions for a normal maturation of the neurovascular system. With the use of endovascular techniques, which represent not only the first choice of treatment but also the only safe therapeutic modality, the natural history of VGAM and their risks may be avoided safely.

RESUMO

Objectives: There is insufficient evidence regarding the potential risk of mobile phone use on mental health. Therefore, the aim of this research was to examine the relationship between mobile phone use and mental health by measuring the levels of depression, anxiety, and stress among university students in Serbia and Italy. Methods: This cross-sectional study was carried out at two distinguished universities in Serbia and Italy from March to May of the 2015/2016 academic year and included 785 students of both genders. The questionnaire was compiled and developed from different published sources regarding the manner and intensity of mobile phone use, along with the Depression Anxiety Stress Scale (DASS 42) for measuring psychological health. The statistical analysis of the data included the application of binary logistic regression and correlation tests. Results: Statistical analysis indicates that anxiety symptoms are somewhat more present in younger students (odds ratio (OR) = 0.86, 95% confidence interval (CI): 0.76-0.96), in those who send more text messages SMSs (OR = 1.15, 95% CI: 1.11-1.31), and in those who browse the internet less frequently (OR = 0.84, 95% CI: 0.73-0.95). Stress is more common in students who make fewer calls a day (OR = 0.79, 95% CI: 0.64-0.97), as well in those who spend more time talking on the mobile phone per day (OR = 1.28, 95% CI: 1.12-1.56). The strongest predictor of high stress levels was keeping the mobile phone less than 1 m away during sleeping (OR = 1.48, 95% CI: 1.12-2.08). Conclusions: The results indicated that the intensity and modality of mobile phone use could be a factor that can influence causal pathways leading to mental health problems in the university student population.

RESUMO

BACKGROUND: The interest in developing risk models in medicine not only is appealing, but also associated with many obstacles in different aspects of predictive model development. Initially, the association of biomarkers or the association of more markers with the specific outcome was proven by statistical significance, but novel and demanding questions required the development of new and more complex statistical techniques. METHODS: Progress of statistical analysis in biomedical research can be observed the best through the history of the Framingham study and development of the Framingham score. RESULTS: Evaluation of predictive models comes from a combination of the facts which are results of several metrics. Using logistic regression and Cox proportional hazards regression analysis, the calibration test, and the ROC curve analysis should be mandatory and eliminatory, and the central place should be taken by some new statistical techniques. In order to obtain complete information related to the new marker in the model, recently, there is a recommendation to use the reclassification tables by calculating the net reclassification index and the integrated discrimination improvement. Decision curve analysis is a novel method for evaluating the clinical usefulness of a predictive model. It may be noted that customizing and fine-tuning of the Framingham risk score initiated the development of statistical analysis. CONCLUSION: Clinically applicable predictive model should be a trade-off between all abovementioned statistical metrics, a trade-off between calibration and discrimination, accuracy and decision-making, costs and benefits, and quality and quantity of patient's life.

RESUMO

In this article, the X-ray and gamma-ray coincidence summing effect in (152)Eu is studied. Coincidence summing corrections and peak and total efficiencies of point and volume sources were determined using the direct matrices multiplication (DMM) method. The theoretically evaluated peak count rates were found to be in good agreement with the experimentally obtained values. Validation was performed by comparing the calculated efficiency curves and the corresponding correction factors with the results obtained using GESPECOR 4.2 software.

RESUMO

Given that a volleyball game requires a certain level of individual anthropological characteristics of young volleyball players to successfully act on situational conditions, and that interdisciplinary approach in the science study is the principal methodological orientation, subject of study in the field of sports is the anthropological status. The aim of this study was to analyze the possible differences in spinal lumbar and abdominal muscles isometric potential of prospective male and female. Sample included 42 subjects (15 male and 27 female subjects), male and female volleyball players, the cadet selection of Serbia, aged 14±0.5 years. Isometric muscle potential assessment was conducted using four standardized motor movement tasks, covering the following areas: static contraction of the flexors of the torso, static contraction of the extensors of the torso, static contraction of the left flexor of the torso, and static contraction of the right flexor of the torso. In addition to the descriptive statistics used, as basis statistics, the t-test for independent samples was used, to compare the mean values of parameters measured in two different groups of athletes ­ volleyball players (girls ­ boys). Descriptive indicators of the sample suggest greater values of deep spinal muscles isometric potential with boys in all study variables. Study results gained by the t-test of independent samples indicate that statistically significant difference exists between their mean results in variables of trunk flexor static contractions and trunk extensor static contractions, at the level 0.001. With other two variables, the values indicate that difference between genders is not significant but accidental. The results of this study regarding static contraction of the right and left lateral flexors of the torso show the lack of statistical significance between male and female cadet volleyball players.


Al considerar que un partido de voléibol requiere cierto nivel de características antropológicas individuales de los jóvenes jugadores de voléibol para actuar con éxito en condiciones situacionales, el enfoque interdisciplinario principal en el estudio de las ciencias del deporte es la orientación metodológica, como también lo es el estado antropológico de los jugadores. El objetivo de este estudio fue analizar las posibles diferencias en la columna lumbar y el potencial isométrico en los músculos abdominales masculinos y femeninos. En la muestra fueron incluidos 42 sujetos (15 varones y 27 mujeres) jugadores de voléibol masculino y femenino de la selección cadete de Serbia, de 14±0,5 años. Se realizó evaluación del potencial muscular utilizando cuatro tareas de movimiento de motor estandarizados en las siguientes áreas: la contracción estática de los flexores del torso, de contracción estática de los extensores del tronco, contracción estática del flexor izquierdo del torso, y la contracción estática del flexor derecho del torso. Además de las estadísticas descriptivas y las estadísticas de base utilizadas, se usó la prueba t para las muestras independientes para comparar los valores medios de los parámetros medidos en dos grupos diferentes de los deportistas - jugadores de voléibol (niñas - niños). Los indicadores descriptivos de la muestra sugieren mayores valores de potencial isométrico de los músculos espinales profundos en niños en todas las variables del estudio. Los resultados del estudio obtenidos por la prueba t de muestras independientes indicaron que existe una diferencia estadísticamente significativa entre los resultados medios en las variables de los flexores del tronco y en las contracciones estáticas de los extensores del tronco, en el nivel de 0,001. Con otras dos variables, los valores indicaron que la diferencia entre ambos sexos no es significativa pero es accidental. Los resultados de este estudio con respecto a la contracción estática del lado derecho y flexores laterales izquierdos del torso muestran la falta de significación estadística entre los jugadores masculinos y femeninos de voléibol.

RESUMO

BACKGROUND: The Northern part of Serbia is hyperendemic-endemic for canine dirofilarioses. Considering this fact, many human dirofilarial infections could be expected, however only about 30 cases in Serbia have been described until today. Aims of this survey were to assess the people reactivity to the antigens of D. repens and D. immitis and to identify risk factors for the contact exposure. METHODS: Investigation included sera taken from 297 people (179 women and 118 men) living in different areas of Serbia (Pancevo, Novi Sad, Zajecar, Leskovac, Vranje, Nis, Pirot). Sera were analysed by means of two indirect enzyme-linked immunosorbent (ELISA) home-designed that use as antigens adult somatic/metabolic polyproteins of D. repens (DR) and D. immitis (DI), respectively. The results were elaborated using the statistical method of descriptive and quantitative analysis. RESULTS: Significant differences by area in the reactivity of human sera to dirofilarial antigens were not observed (p = 0.056). A high seroreactivity was demonstrated in people from the towns of northern Serbia (Pancevo = 27,1%; Novi Sad = 16,3%), as well as in people from Zajecar (eastern Serbia = 15,8%) and Vranje (southern Serbia = 15,1%). No differences were evidenced between people reactivity to polyproteins of the two dirofilarial species, nor differences related to the gender of examinees. Factor risks evidenced were: i) place of residence; ii) spending work time outdoors during the mosquito season; iii) spending time outdoors and nearby rivers, lakes, swamps or canals; unespectedly, iv) cat owning. CONCLUSION: The findings emerging from this investigation indicate that clinicians and public health authorities should pay greater attention to this zoonosis. Continuing education and training of physicians will greatly contribute to the knowledge of the actual impact of filarial worms on animal and public health, and allow for the planning of suitable measures to prevent the infections.
