Authors: Alves Ferreira Neto José , Oliveira Helaine Cristina de , Oliveira Nayara Kelly de , Cunha Amanda Da Silva
Published: February 2020

O objetivo deste trabalho é discutir as causas das atuais inundações urbanas brasileiras e apresentar meios e técnicas disponíveis para minimizar ou findar esses eventos, considerando que o crescimento da população urbana brasileira nas últimas décadas gerou problemas relacionados ao escoamento superficial de águas pluviais nas cidades. As altas taxas de impermeabilização do solo acarretam perda da capacidade de infiltração da água pluvial culminando em inundações urbanas, com isso viu-se a necessidade de criação e implantação de novas tecnologias que podem diminuir ou cessar tais problemas. Técnicas de pavimentação com materiais que permitem maior infiltração de águas pluviais representam métodos de redução do escoamento superficial e aumento da permeabilidade do solo. Este artigo foi realizado com base em referenciais bibliográficos que tratam de assuntos relacionados à drenagem urbana, escoamento superficial e tipos de pavimentos.

Authors: Adnyani Luh Putri
Published: February 2020

Distribution of medical facilities in Indonesia is uneven, so residents in remote islands have difficulties to reach it. We need to build health boat, a floating facility that provide standard services like in the hospital, especially in Derawan and Tarakan Islands in East Kalimantan. This Health boat has a homebase in Balikpapan. Therefore, the condition of the sea between Balikpapan, Derawan, and Tarakan need to be reviewed. One method to determine the condition of the sea is analysis of meteorological and oceanographic, which enable us to get the maximum wave height estimation. Long tern wave forecast can be obtained by using statistical methods of measurement to provide data of high wave in 1, 10, 25, 50 and 100 years.

Published: February 2020

Currently Information Technology is increasingly needed by many organizations. Implementation of inappropriate IT in the organization will be a burden, even can hinder the development if not in accordance with the vision and mission of the organization. Weill and Ross also stated, 48 percent of companies that do IT investment cannot increase the expected value. A solid foundation in the execution process of IT implementation plays an important role in determining the success or failure of the company to achieve the desired goals. To build a solid foundation on the execution process of IT implementation, one of the important things to note is Enterprise Architecture (AE). Enterprise architecture provides a long-term view of the processes, systems and technologies in the company, so there is a harmony between business and IT both for now and for the future to achieve the desired goals. Currently the use of cloud computing technology increasingly used in organizations. Organizations typically have a variety of different platform integrated applications that are used to support their business processes. There are many frameworks used to build AE, but there is no AE framework specifically addressing AE design on cloud computing and supports multiplatform and cloud-based IaaS. This paper discusses the use of TOGAF and CERM to educational institution that have many integrated multiplatform applications. AE design that was built is validated by using Enterprise Realization Score Card (EARS) to assess whether it can be implemented well in the organization.

Published: February 2020

Bark midrib are not fully utilized. Utilize the characterization of the fiber and process it into polymer composites with natural fiber reinforcement. The study was conducted using a variety of chemical treatments in the form of bark midribs without treatment, delignification treatment that is immersion using NaOH media concentration of 1%, 5%, 10% with 3 hours immersion time and bleaching treatment using H2O2 media 2% concentration with immersion time 30, 60 and 90 minutes. In obtaining suitable properties, tensile tests, impact tests, Scanning Electron Microscopy (SEM) images, and Fourier-Transform Infra-Red (FTIR) tests are performed. Optimal delignification treatment at 5% NaOH concentration with a tensile test value of 25.47 MPa (increasing 76.86%) and an impact test value of 11.95 kJ/m2 (increasing 11.45%). The optimal bleaching treatment at 90 minutes immersion with a tensile test value of 35.09 MPa (increased 36.36%) and impact test value of 13.77 kJ/m2 (increased 15.22%). The results of SEM images show that the bark midrib fiber composite without treatment has a lousy interface, delignification treatment with a reasonable good interface, and bleaching treatment with an excellent interface. FTIR test results showed that the bark midrib fiber composite without treatment had a cellulose component but hemicellulose and lignin levels still dominated. Based on the results of the study, bark midrib fiber with delignification chemical treatment using 5% NaOH for 3 hours followed by bleaching treatment using 2% H2O2 for 90 minutes is the treatment with the best results and then applied to a natural fiber composite product.

Published: February 2020

We investigate the amorphous formation behavior on hydrocarbon molecular ion implantation conditions such as hydrocarbon molecular ion size by X-ray photoelectron spectroscopy (XPS). The cross-sectional radius of the amorphous region was obtained from the peak intensity of the amorphous component in Si 2p spectra analyzed by XPS, and using columnar formula for a model. We confirmed that the cross-sectional radius of the amorphous region formed by hydrocarbon molecular ions differs greatly from that formed by monomer carbon ions, and increases by 0.078 nm as the number of carbon atoms composing the hydrocarbon molecular ion increases. The dependence of amorphous formation on the hydrocarbon molecular size is related to the C–C binding distance, and the ratio of increase in the amorphous cross-sectional radius corresponds to half of the C–C binding distance. Therefore, the collision behavior of hydrocarbon molecular ions during implantation predominantly influence the size of hydrocarbon molecular ions.

Authors: Martymianova Larysa O , Tykhonova Tetiana M , Bychkova Olga Yu. , Lysenko Nataliia V , Barabash Nadiya Ye
Published: February 2020

Introduction: No doubt today that atrial fibrillation (AF) is associated with an increased risk of thromboembolic events. Simultaneously we did not find any investigation about
the links between general cardiovascular risk (GCVR) and the frequency forms and functional parameters of the heart in patients with AF.
The aim:To study the frequency forms and functional indices of the heart in patients with permanent AF in GCVR groups.
Materials and methods: 157 patients with permanent AF (99 men and 58 women) aged 64.6 ± 9.7 years were examined. The frequency of ventricular contractions, the
duration of the ventricular complex (QRS), the corrected QT interval (QTc), power indices of the spectrum of heart rate variability (HRV) were measured by ECG. Echocardiographic
parameters were studied using a SIM 5000 plus medical diagnostic automated echocardiograph. Patients were classified into GCVR groups.
Results and conclusions: The existence of relationships of GCVR with frequency forms of AF and functional indicators of the heart was established. In patients of the class I-III
GCVR groups, the tachysystolic form of AF prevailed. Its frequency increases with the rise of the GCVR class. In GCVR IV, redistribution of forms of AF occurs in the direction of
normosystolic ones. Among the functional parameters of the heart, the left ventricular ejection fraction and the power of the HRV spectra are most closely associated with GCVR.
MODELLING OF OILY RAW MATERIAL EXCRACTION PROCESS
Authors: Polievoda Yurii , Tverdokhlib Igor , Bandura Valentina
Published: February 2020

This paper concentrates on approaches to mathematical modelling of oily raw material extraction process. «Evolution» of modeling hypothesis based on analysis of differential diffusion equation under the right boundary and initial conditions; on simplified model of Fick's equation and on material balance equation; on mass transfer model in adsorption pore volume; on model for the surface layer by analogy of Van der Waals equation; on Gibbs' model based on the abrupt change of phases due to the intermolecular forces; on the simplest Langmuir equation model; on lattice-based models of Guggenheim, Pryhozhyn, Everett, Ohm, Briukhovetskyi and others. The fact that we need to know a large number of micro - parameters makes these models difficult to use in practice.
Under normal extraction conditions, the flow, which comes out of solid phase, collides with the resistance of the diffusion boundary layer, which presents a tangible obstacle affecting the duration and quantity of special-purpose component extraction. As the boundary layer thickness depends on the hydrodynamics of the process, under the influence of the microwave field his obstacle is almost insensible, as the intense movement of liquid reduces its thickness. The main factor acting on the quantity of extracted substance is a pressure difference in capillaries and in the flow of extraction agent and mass transfer coefficient. The effect of pulse microwave input during the extraction transfers the process of diffusion from the external environment to internal, because internal pressure diffusion dominates in this process, but not the convective diffusion with the influence of external agent.
ON THE POSSIBILITY OF STAGNATION OF FREE OSCILLATIONS OF A NONLINEARLY ELASTIC OSCILLATOR WITH A LINEAR VISCOUS RESISTANCE
Authors: Vasyl Olshanskiy , Stanislav Olshanskiy
Published: February 2020

The free oscillations of an oscillator with a power-nonlinear elasticity characteristic under the action of linear viscous resistance are considered. Using the energy balance method, which is widespread in mechanics, the calculation of the amplitudes of free damped oscillations is reduced to calculating the roots of an algebraic equation, which has an exact analytical solution only with linear elasticity of the oscillator. In the case of an arbitrary positive indicator of nonlinear elasticity, a numerical solution of the equation is required. For this, the Newton's iterative method was used in the work, which has fast convergence of iterations at an arbitrary initial approximation. According to the results of the analysis of the coefficients of the equation established, that in the case of a rigid characteristic of elasticity, when the nonlinearity is greater than unity, the oscillations are reduced to a finite number of decaying ranges, that is, they are limited in time, and in the case of a soft characteristic of elasticity, when the nonlinearity is less than unity, they continue to infinity, as linear dissipative oscillator. The research is given by the method of energy balance and numerical integration of the differential equation of oscillations on a computer. The work of the force of viscous resistance is calculated approximately using periodic Ateb functions that accurately describe free undamped oscillations in the absence of resistance. As a result, approximate iterative dependences are obtained for calculating the amplitudes of the ranges that decay during movement. The numerical results obtained using approximate formulas and numerical computer integration of the nonlinear Cauchy problem are compared. Their satisfactory agreement was noted. A satisfactory agreement was noted between the results for both hard and soft elastic characteristics, which confirmed the adequacy of approximate analytical solutions to the dynamics problem. The main advantage of the described approximate calculation method is that there is no need to build an analytical solution to the nonlinear differential equation of motion of the oscillator, which is a rather complicated mathematical problem. Furthermore, it made it possible to establish conditions under which the oscillator with a viscous and dry friction resistance have similar oscillation properties.

Authors: Ferber Asaf , Hirschfeld Lior
Published: February 2020

In this paper we prove an optimal co-degrees resilience property for the binomial $k$-uniform hypergraph model $H_{n,p}^k$ with respect to perfect matchings. That is, for a sufficiently large $n$ which is divisible by $k$, and $p\geq C_k\log {n}/n$, we prove that with high probability every subgraph $H\subseteq H^k_{n,p}$ with minimum co-degree (meaning, the number of supersets every set of size $k-1$ is contained in) at least $(1/2+o(1))np$ contains a perfect matching.

Authors: Pavese Francesco
Published: February 2020

A $q$-covering design $\mathbb{C}_q (n, k, r)$, $k \ge r$, is a collection $\mathcal{X}$ of $(k-1)$-spaces of $PG(n-1, q)$ such that every $(r-1)$-space of $PG(n-1,q)$ is contained in at least one element of $\mathcal{X}$ . Let $\mathcal{C}_q(n, k, r)$ denote the minimum number of $(k-1)$-spaces in a $q$-covering design $\mathbb{C}_q (n, k, r)$. In this paper improved upper bounds on $\mathcal{C}_q(2n, 3, 2)$, $n \ge 4$, $\mathcal{C}_q(3n + 8, 4, 2)$, $n \ge 0$, and $\mathcal{C}_q(2n,4,3)$, $n \ge 4$, are presented. The results are achieved by constructing the related $q$-covering designs.

In the current paper were studied a number of 200 sturgeons from Polyodon spathula of 4th summer (P.s.3+) breed, reared in a fishery farm from North-East of Romania. Studying of modification of sensorial characteristics of meat, analysed just after fishing and during preservation by refrigeration during 15 days (+2 � +4oC), show an optimal keeping period by refrigeration of the studied fishes for 5-6 days. The pH level from the studied muscles oscillated between values 7.9 and 7.11, after slaughtering, and at 24 h after slaughtering between 6.88 and 6.89. The water content of fillet (lateral muscles) had values of 75.41%; protein content of fillet (lateral muscles) had values of 19.89%; lipid content of fillet (lateral muscles) was 3.45%; collagen content of fillet (lateral muscles) had values of 4.14%. The values of water-protein rate (w/p = 3.79) placed the analyzed paddlefishes in the second category; energetic value of fillet gathered from studied fishes was 114.31 kcal/100 g. The rate of amino-acids from the total sum was 26.23% for the essential amino acids, 4.61% for semi-essential amino acids and 69.16% for non-essential amino acids. As rate the quantity of saturated fatty acids recorded the value of 25.64% for epaxial muscles, respectively 25.83% for hypaxial muscles; rate of mono-unsaturated fatty acids was 54.77% for epaxial muscles and 54.50% for hypaxial muscles; poly-unsaturated fatty acids had a rate of 19.59% for epaxial muscles and 19.67% for hypaxial muscles. Through histological studies for establishing the rate of muscular and conjunctive tissues from meat of studied paddlefishes, was observed that in case of lateral muscles mean diameter had an intermediary value of 43.42 �. Those data leaded to obtain a mean area for transversal section of 1485.74 �2. Mean diameter of muscular fibre (43.42 �) characterize a meat with fine texture. Profile on transversal section of muscular fibres had an ellipsoidal shape; fact which was enlightened by the rate between great diameter and small diameter (GD/SD) which varied between 1.35/1 -1.61/1. The rate of the main tissue categories in composition of lateral muscles gathered from analysed paddlefishes revealed the fact that mean rate of muscular tissue was of 70.47%, while mean rate of conjunctive tissues was of only 29.52%.

Antibiotherapy is the main determinant of Clostridium difficile infection due to the imbalance determined in the intestinal flora. Clostridium difficile infection can be considered a current public health problem, given the increased incidence, both as a nosocomial infection as well as at community level, by excessive, uncontrolled and unjustified use of antibiotics, high contagiousness, negative influence on health systems in the increased number of days of hospitalization and implicitly increased costs, and last but not least, the substantial deterioration of the quality of the patient�s life. The retrospective study over a 12-month period over a group of 106 patients revealed the following profile of the patient affected by Clostridium difficile infection: females, aged 66.75 � 15.66, from the urban area, hospitalized in the medical section, who had diarrhea more than 2 days after admission, but up to 28 days after this event, due to prolonged antibiotic therapy with ceftriaxone, associated with a gastric secretion inhibitor, on a background of multiple associated pathologies. It is very important for all health systems to control this phenomenon and this is only possible by applying effective measures to prevent the onset of CDI, of relapses and contamination, thus identifying the judicious use of antibiotics.

In this work a comparative theoretical analysis vs. experimental study on human blood under a magnetic field stimulation is presented. Twenty samples of leukoreduced human blood were stimulated with an alternant magnetic field using a Helmholtz coil system; this magnetic field induced an electromotive force in them. Theoretical calculations were performed for the induced electromotive force in a simple model of blood tissue under magnetic stimulation at frequencies: 50 Hz, 100 Hz, 800 Hz, and 1500 Hz. Experimental measurement was performed at the same frequencies for comparison purposes. Results show a high correlation between theoretical and experimental study, as well as effects of agglutination in the stimulated blood cells.

The constantly and intensely changing modern society has a negative influence on the the general population�s health status. Risk factors being deeply inserted in the structure of the modern society can hardly be influenced and corrected. The aim of the study was the lifestyle- and diet-related comparison of two distinct adult populations from Romania: Bacau and Tirgu Mures. Material and methods: We evaluated the dietary habits, alcohol consumption and physical activity by a complex, validated questionnaire. Body mass index was also determined. The adult population from Tirgu Mures numbered 352 subjects, who were compared to the adults from Bacau, numbering 231 individuals. The considered threshold of significance was 0.05. Body mass index is over the normal range in more than 2/3 of the subjects. The overweight occurrence was 37.95%. The majority of the subjects (77.5%) has regular daily exercise (30 minutes or more). Daily alcohol consumption was present in 42.42% of the cases. Dietary habits were also analyzed: 61.9% of the subjects consume breakfast daily, and 46.94% of them consumes snacks between meals 2-3 times per week. A statistical difference could be observed regarding the frequency of breakfast consumption and body mass index (p-0.042): 2/3 of the studied adults from Tirgu Mures who eat breakfast sometimes having their body mass index over 25 kg/m2. Regarding physical activity a significant difference could be observed in case of those who responded rarely or never (p-0.027) (76.0% of Mures county with this response vs. only 24.0% in Bacau). The frequency of alcohol consumption is higher in Tirgu Mures and surroundings in case of once or several times per week consumption (p-0.005). Instructional and educational interventions targeting the development of healthier lifestyle habits in general population are worthy and needed to reduce the risk factors associated with the development of cardiovascular and metabolic diseases and reducing the burden upon the society of these diseases.

The aim of the present study is to compare the marginal adaptation of direct, semi-direct and indirect restorations made with nanofill and microhybrid composite materials and ormocers materials bonded with SE adhesives at the dentin and cementum. 120 standardized class II cavities were prepared (40 for each techniques- RD, RSD, RI) with the gingival margin over and below to the cementum-enamel junction. The teeth (n= 20) were restored using one of three adhesive systems (OptiBond XTR, G-Premio Bond bottle refill, Futurabond U) with incrementally placed composite restorations and ormocers. After applying the various restorations, the teeth were prepared for SEM analysis to check the marginal adaptation by the presence of continuous margins or gaps. Comparative analysis of treatment methods and materials used was performed by statistical analysis of Chi-square test data, the statistical significance was p [0.05 and Fisher�s Exact Test for validation of results. It was found that among the three materials used for RD, RSD, RI both at the dentin and the cementum, there are no significant differences (RD d = 0.661, RSD/d = 0.755, RSD/c = 0.942; RI/d = 0.739; RI/c = 0.985). Comparison between the presence of continuous margins/gaps subgingivally and supragingivally at the three types of restorations shows that there are significant differences between the marginal adaptation at the cementum and dentin to all the restoration techniques used (p [0.05). Direct and indirect restorations with nanocomposites and ormocers bonded with 1-step SE adhesive are the best solutions for restoring the posterior teeth.

Otalgia during airplane flights is a common complaint among patients. This occurs due to the changes in air pressure during take-off and landing that affect middle ear and inner ear. The eustachian tube is responsible with equalizing pressure but in many cases, it happens insufficiently leading to mild to severe pain, hearing loss, tympanic membrane rupture and even inner ear lesions. The aim of this paper is to asses the efficacy of two decongestants, oral pseudoephedrine versus topical xylometazoline in preventing otic barotrauma.

Septoturbinar synechia is a pathological adherence between the mucosa of the turbinate and the nasal septum. Synechiae result after endoscopic sinus surgery or can be caused by trauma, infections, autoimmune pathologies, drug abuse, chemical burns, radiotherapy or intensive nose packing. The treatment for septoturbinar synechiae is surgery with the ablation of adherences. In this paper we will present a new surgical method for the ablation of synechiae under endoscopic control, using coblation.

Nephrolithiasis in young patients is today a public health problem with an increasing prevalence in industrialized nations. Between 01 January 2016 and 1 September 2018, we have evaluated patients aged between 18 and 40 years old referred to our clinic and diagnosed with urinary stones. After 30 days at least, it was confirmed using imaging stone-free status of the patient and then the 24h urine composition was performed. We have enrolled 110 patients, 58 males and 52 females, with a mean age of 29.55 years. Surprisingly, in 71 cases (64.54%), patients had hypokaliuria, 37 normokaliuria cases (33.63%) and two cases of hyperkaliuria (1.81%). We divided the patients into two main groups: those with hypokaliuria and those without. In those with hypokaliuria, the mean concentration was 22.53 mmol/L, while in the other group 52.77 mmol/L. Patients with low urinary potassium level had a slightly acid urinary pH (5.6 vs. 5.86) and lower urinary density (1012.96 vs. 1016.15 kg/m3) than in others, however higher than the recommended levels in lithiasic patients. Urinary magnesium level was lower (3.68 mmol/24h vs 3.87 mmol/24h) in the hypokaliuria group. Therefore, hypokaliuria was positively correlated with two protective factors. Patients with hypokaliuria revealed low urinary levels of lithogenic factors. Natriuria was significantly lower in patients with hypokaliuria (67.81 vs. 120.77 mmol/L, p [ 0.05). In addition, we noticed the same thing on urinary calcium level (4.02 mmol/24h vs 4.98 mmol/24h) but with no statistical significance (p = 0.16). Hypophosphaturia was more common in those with hypokaliuria (18.89 vs. 26.72 mmol/24h, p [ 0.05). The 24-hour urine analysis remains an important component of the metabolic workup for recurrent renal lithiasis. It seems that many of the young lithiasic patients in our geographic area have a low urinary potassium. Paradoxically, patients with hypokaliuria seems to have also hyponatriuria and hypophosphaturia. Through this study, we hope to make correlations between the risk of recurrent lithiasis -being a recognized high risk among young patients - and changes in 24-hour urine parameters found in the initial assessment.

Some new N-acylhydrazones 7a-c having dibenzo[a,d][7]annulene moiety were synthesized by condensation of corresponding hydrazide 5 with aromatic aldehydes. The structures of these newly compounds were elucidated by IR, 1H-NMR, 13C-NMR, and elemental analysis. In the view of the therapeutical potential of the newly compounds, we evaluated their toxicological profile using Daphnia magna bioassay.

The use of detergents with enzymatic activity is very popular if we consider their real economic advantages - reducing energy and water consumption but also reducing the environmental impact by using more biodegradable components related to organic and inorganic components. The purpose of our study was to evaluate the impact of environmental factors such as the variability of water hardness in the public water supply network and the temperature applied to the amylolytic, lipolytic and proteolytic enzyme activity of 6 detergents available on the market. The determinations were performed by modified methods from the European Pharmacopoeia 8th Edition in determination the enzymatic activity of the pancreas powder. The determinations show a significant influence of increased water hardness on lipase and protease activity in detergent (p [0.01 *) between extreme hardness values, while amylolytic activity does not vary significantly with increasing water hardness.

The aim of our study was to assess the percutaneous coronary angioplasty versus coronary artery bypass grafting in the treatment of the left main coronary artery disease. The study was a prospective, analytical, observational descriptive one, it included a total number of 83 patients, consecutively included in order to avoid bias, for a period of three years between October 2012 and December 2015. The follow-up was performed for 3 years, initially at one month, then at an interval of three to six months. The primary clinical endpoint was mortality of any cause of the patients included in the study. Other main objectives assessed in our study were symptomatic ischemic heart disease manifested with angina pectoris, the need for myocardial revascularization, nonfatal myocardial infarction, and reduction of left ventricular ejection fraction. In patients with LMCAD, we noticed an increase in mortality in patients with PCI vs. CABG, recurrence of angina pectoris, acute myocardial infarction, myocardial revascularization, and depression of the ejection fraction of the left ventricle. In conclusion, the treatment of left main coronary artery disease by using coronary artery bypass grafting is superior to treatment using percutaneous coronary angioplasty.

Bone defects are a challenge to any and in fact every orthopedic surgeon, be they as a consequence of trauma, peri-implant bone loss as is the case in revision surgery or, more often than not, in tumors of the bone. These defects are in most cases difficult to reconstruct, but even more so in the case when they are located around the major joints of the lower limb, i.e. the hip and the knee. We focus in this article on acetabular bone defects as well as on defects around the knee (distal femur and proximal tibia). We present implant possibilities and modern means of reconstructing the bone defect using augments. We also present three representative cases from our Clinic, to further exemplify the discussed concepts. We present our opinions on reconstructing bone defects after tumor and revision surgery in the hip and knee and we draw conclusions.

The specific objective of the present study is to assess the interactions between cells from a human gingival epithelial cell line and various aesthetic materials used in modern prosthetic dentistry. For this study six types of dental materials were selected: Cr-Co non-precious metal alloy, ceramics applied on Cr-Co non-precious metal alloy, zirconia, ceramics applied on zirconia, polymethyl methacrylate and pressed ceramics/lithium disilicate. Cells from a human gingival epithelial cell line, Ca9-22 (Health Science Research Resources Bank), were cultured on the chosen surfaces for 3, 5 and 7 days. Cellular proliferation, cell attachment (using Multiplex Arrays Technology) and cytotoxicity (MTT- Assay) were evaluated at distinct predetermined intervals. Measurements performed at each distinct predetermined interval showed no significant difference for cell proliferation and cytotoxicity between the selected surfaces, however the highest levels were registered for the polymethyl methacrylate surface. Different attachment patterns were observed for epithelial cells attached on substrates, such as significantly different levels of adherence of E-Cadherin and N-Cadherin molecules; E-Cadherin adhesion levels indicate that pressed ceramics may be the dental material which, compared to the selected materials, influences the least the homeostasis of oral mucosa.

Gestational Diabetes Mellitus is a severe complication in every pregnancy at risk, influencing the clinical outcome in postpartum evolution and affecting women predisposition to future diabetic pathologies. Our study goal was to determine which type of hormonal or non-hormonal contraception method nondiabetic women with past GDM used in their first 6 months postpartum. Results showed that Progestogen-only pill (40.0%) and Levonorgestrel-releasing intrauterine device (23.1%) were the most used contraceptives. Around 56% of the patients were not satisfied using the Barrier method, whereas 67% of the patients in the less than 25 kg/m2 BMI group reported adverse events. Special consideration must be applied in order to support obese patients and those perpetuating noxious habits.

Along with the findings of recent years in medical imaging, a wide range of contrast agents have been developed and used in order to improve the quality of the images acquired and to get a diagnosis with the highest accuracy. Modern substances used in nuclear magnetic resonance imaging contain ions with one or more free electrons, which have fewer side effects and are eliminated by the kidney in a short time. This is used in MRI practice in T1 section, where these substances reduce relaxation time and increase signal strength. Our study included a group of 17 patients diagnosed with cervical cancer, who were also investigated by MRI technique with paramagnetic contrast agents. We followed the cervix-related aspects in the T1 and T2 sections and applied the EMVI score criteria to determine the level of extramural invasion of the blood vessels. The results are conclusive in the advanced stages of the disease when EMVI staging criteria are similar to those of TNM.
Medical Liability for Off Label Use of Drugs in Romania

Breaking the limits of the risks for the human body, health or even the life of the patient, as assumed by the pharmaceutical producers, by using a drug off label, for its side effects, in another purpose or even against the purpose for which the drug was authorized by the National Agency of Medicine and Medical Devices, is not in itself illegal if the off label use has the common consent of both the doctor and the patient for a treatment and only for a treatment which, although a spread procedure, has little or no scientific support. But if the patient is subjected to unreasonable risks, endangering his body, health or life beyond the possible benefits of the treatment, without being informed about the lack of scientific support, the doctor is liable not only for malpractice (civil medical liability) but also for a criminal offence.
