Aim To demonstrate the effects of early diagnosis of overuse syndrome in the wrist on healing, pain intensity and quick recovery to daily work and sport activities. Methods This clinical retrospective study included 60 patients of both sexes aged from 22 to 44 years, with pain in the wrist and clinical signs of creeping tenosynovitis. Patients were divided into two groups: the first group - persons doing sports activity, and the second group - patients who did not deal with sports activities. Results Females in 31 (51.7%) cases compared to males with 29 (48.3%) were slightly more represented in the total sample. Patients with injuries due to sports activities had previously reported to the physician and the diagnosis was set at an average of 3.1±0.9 days after the first symptoms (the range of 2-5 days), compared to the patients of the second group whose diagnosis was set at an average of 4.7±1.1 days after the first symptoms (p<0.05). Conclusion Patients involved in sports activities were more motivated for faster recovery, they had earlier doctor's examination with rapid reduction of subjective symptoms during intensive physical therapy.

Analysis of daily solar irradiation variability and predictability in space and time is important for energy resources planning, development, and management. The natural variability of solar irradiation is being complicated by atmospheric conditions (in particular cloudiness) and orography, which introduce additional complexity into the phenomenological records. To address this question for daily solar irradiation data recorded during the years 2013, 2014 and 2015 at 11 stations measuring solar irradiance on La Reunion French tropical Indian Ocean Island, we use a set of novel quantitative tools: Kolmogorov complexity (KC) with its derivative associated measures and Hamming distance (HAM) and their combination to assess complexity and corresponding predictability. We find that all half-day (from sunrise to sunset) solar irradiation series exhibit high complexity. However, all of them can be classified into three groups strongly influenced by trade winds that circulate in a “flow around” regime: the windward side (trade winds slow down), the leeward side (diurnal thermally-induced circulations dominate) and the coast parallel to trade winds (winds are accelerated due to Venturi effect). We introduce Kolmogorov time (KT) that quantifies the time span beyond which randomness significantly influences predictability.

Aim To investigate whether or not additional treatment of ischemic heart disease with trimetazidine could improve effort tolerance and overall quality of life of patients with ischemic heart disease. Methods The study included 200 patients with ischemic heart disease. The sample was divided into 2 randomly selected groups: experimental and control group. The diagnostic procedures included: trade-mill test according to Bruce protocol, heart ultrasound for assessment of ejection fraction, test for the assessment of quality of life and subjective problems (Short Form SF 36). Patients were tested for time of discharge from hospital, after 6 and 12 months, including re-evaluation of the overall condition of the previous period. Results Patients have been tested for the tolerance of effort with the measurement Metabolic Equivalent of TASK (METs), which is the equivalent of physical labor. Patients treated with trimetazidine since the time of hospital discharge achieved an average of 3.68, after 6 months 5.68, and after 12 months 7.79 METs. The control group achieved 3.68, 3.59 and 3.87 METs, respectively. Using Mann-Whitney test no difference at discharge time (p=0.880), but after six and twelve months there was some difference (p<0.001). Results of ejection fraction measured by echocardiography were similar. No difference between the two groups with regard to time of discharge (p=0.821, but p<0.001 after six and twelve months, respectively). Conclusion Patients treated with conventional therapy including trimetazidine have better tolerance to effort and better ejection fraction on heart ultrasound examination in comparison with those treated without trimetazidine, so trimetazidin improve the metabolic balance of heart muscle.

Aim To assess whether the quality of diabetes care provided by a family medicine team changed over the course of four years and to identify potential gaps in our practice in order to improve it in the future. Methods An audit was carried out for randomly selected 120 medical records (MC) from the Diabetes Registry of patients with type 1 or 2 diabetes mellitus treated by one family medicine team for four consecutive years, from 2013 to 2016. We examined demographic data (gender, age, diabetes type, family history), annual examinations (glycated haemoglobin, blood glucose, lipid profile, neurological examination, urinalysis, foot care, ocular fundus and body mass index), prescribed insulin or other drugs and patients' education. Results Over the years females dominated with the maximum of 63% in 2013. In most years type 2 diabetes occurred in 93% of patients. The acceptable level of monitoring included examination of ocular fundus, lipid profile or total cholesterol, blood pressure, fasting and postprandial blood glucose with more than 80% annually. A low level of monitoring complications of diabetes was found on monofilament test, 26% in 2016, urinalysis, 20% in 2016 and examination of feet with the maximum of 46% in 2013. Outcome measurement showed satisfactory levels of glycated haemoglobin of 60% in 2014, blood pressure 76% in 2014, fast 56% and postprandial blood glucose of 73% in 2013. Conclusion We still need to find effective interventions that will lead to improvement of care for patients with diabetes in family medicine.

Aim To determine capabilities and potential of contrast enhanced magnetic resonance imaging (MRI) enterography in order to establish the diagnosis and to evaluate severity and activity of intestinal inflammation. Methods Fifty-five patients with suspicion for presence of Crohn's disease were evaluated. All patients underwent contrast enhanced MRI enterography and diffusion weighted imaging (DWI), and subsequently endoscopic examination or surgical treatment. Four parameters were analysed: thickening of the bowel wall, and presence of abscess, fistula and lymphadenopathy. Results Comparing results of DWI and contrast enhanced MRI enterography a significant difference between results given through diffusion and histopathological test was found, e.g. a significant difference between results obtained through diffusion and MRI enterography was found. MRI enterography sensitiveness for bowel wall thickening was 97.7% and specificity 70%, whilst DWI sensitivity for bowel wall thickening was 84% and specificity 100%. The diagnostics of abscess and fistula showed no significant difference between DWI and MRI, while in lymphadenopathy significant difference between contrast enhanced MRI enterography and DWI was found. Conclusion Contrast enhanced MRI enterography in combination with DWI allows for excellent evaluation of disease activity, but also problems or complications following it. The examination can be repeated, controlled, and it can contribute to monitoring of patients with this disease.

Aim To investigate predictive value of procalcitonin in diagnosis of sepsis in predicting positive blood culture, and possibility to predict final outcome in septic patients. Method This prospective study involved 106 hospitalized patients who met two or more criteria for systemic inflammatory response syndrome (SIRS). In comparison to Sepsis Related Organ Failure Assessment score (SOFA) and Acute Physiology and Chronic Health Evaluation (APACHE) II score procalcitonin (PCT), C-reactive protein and lactate levels were used to predict final outcome in septic patients (recorded as 28-day survival or non-survival). Using Receiver operating characteristic (ROC) curve the area under the curve (AUC) was calculated for diagnostic value and accuracy of different parameters with the best sensitivity and specificity for given cut-off values. Result Fifty-two out of 82 patients with documented sepsis had positive blood culture. Procalcitonin showed the best predictive value for both diagnosis of sepsis and bacteraemia with the cut-off value of 0.57 ng/mL (AUC 0.99) and 4.68 ng/mL (AUC 0.94), respectively. Serum lactate level showed the best 28-day mortality predictive value with the cut-off value of 3.25 mmol/L (AUC 0.95), and procalcitonin with the cut-off value of 15.05 ng/mL (AUC 0.92), followed by SOFA (AUC 0.92), CRP (AUC 0.84) and APACHE II score (AUC 0.83). Conclusion Monitoring of PCT in SIRS-positive patients raises possibility to distinguish between patients with sepsis and those with non-infectious SIRS. A significant correlation between PCT and SOFA, and APACHE II score in non-surviving septic patients indicates that PTC combined with clinical score could be useful for assessing severity of infection.

For companies active in various sectors, the implementation of transport services and other logistics activities has become one of the key factors of efficiency in the total supply chain. Logistics outsourcing is becoming more and more important, and there is an increasing number of third party logistics providers. In this paper, logistics providers were evaluated using the Rough SWARA (Step-Wise Weight Assessment Ratio Analysis) and Rough WASPAS (Weighted Aggregated Sum Product Assessment) models. The significance of the eight criteria on the basis of which evaluation was carried out was determined using the Rough SWARA method. In order to allow for a more precise consensus in group decision-making, the Rough Dombi aggregator was developed in order to determine the initial rough matrix of multi-criteria decision-making. A total of 10 logistics providers dealing with the transport of dangerous goods for chemical industry companies were evaluated using the Rough WASPAS approach. The obtained results demonstrate that the first logistics provider is also the best one, a conclusion confirmed by a sensitivity analysis comprised of three parts. In the first part, parameter ρ was altered through 10 scenarios in which only alternatives four and five change their ranks. In the second part of the sensitivity analysis, a calculation was performed using the following approaches: Rough SAW (Simple Additive Weighting), Rough EDAS (Evaluation Based on Distance from Average Solution), Rough MABAC (MultiAttributive Border Approximation Area Comparison), and Rough TOPSIS (Technique for Order of Preference by Similarity to Ideal Solution). They showed a high correlation of ranks determined by applying Spearman’s correlation coefficient in the third part of the sensitivity analysis.

Background There is international consensus around a core set of variables (cSLE-CRVs) to assess response to therapy with childhood-onset systemic lupus erythematosus (cSLE) [global assessment of patient well-being (Patient-global), physician assessment of cSLE activity (MD-global), disease activity index score, urine protein to creatinine ratio (PCR), Child Health Questionnaire physical function summary score (CHQ-Phs)]. Percentage changes of these cSLE-CRVs are used in the Provisional PRINTO-ACR- EULAR Criteria of Response to Therapy of cSLE (PCI). In a small dataset, we have previously shown that the PCI and the Systemic Lupus Responder Index only have fair accuracy in detecting cSLE improvement. The Objective of this research was to 1) validate the PCI and 2) develop for Children an Index of Lupus Improvement (CHILI) as a tool to measure response to therapy, with focus on clinically relevant improvement (CRIcSLE). Methods Pediatric subspecialists (n=213) in treating cSLE were invited to define CRIcSLE and rate a total of 433 unique patient profiles for the presence/absence of CRIcSLE and various levels of improvement. Patient profiles included the cSLE-CRVs and routine laboratory tests at a baseline and follow-up time-point. To measure CRIcSLE we tested the PCI, and developed the candidate CHILI criteria that considered a) absolute and b) percentage changes of the cSLE-CRVs (baseline vs follow-up) in a trainings-dataset and initially validated these criteria in the validation-dataset. Criteria accuracy was assessed by kappa statistics (PCI) and the area under the ROC curve (AUC; range: 0–1)], respectively. Results During an international consensus conference agreement on a definition of CRIcSLE was achieved. Response rate to patient profile ratings was 91% (194/214). The PIC had no more than fair accuracy (kappa 0.92, sensitivity: >93.1%; specificity: >73.4%), respectively. Conclusions The CHILI is a new highly accurate index to capture improvement in the overall course of cSLE. This index is also useful to categorize the degree of cSLE response to therapy.

Analysis of flow around the high-speed body with an irregular shape (such as fragments/shrapnels formed after the detonation of high explosive projectiles) was performed using the method of numerical simulations. For supersonic motion regime, pressure and velocity flow fields, as well as the formation of shock waves, around an irregularly shaped body were analyzed. Also, streamlines around an irregularly shaped body moving through the atmosphere were visualized (Ansys Fluent) and analyzed.
