OBJECTIVEPatient-reported outcome measures (PROMs) are standard of care for the assessment of functional impairment. Subjective outcome measures are increasingly complemented by objective ones, such as the “Timed Up and Go” (TUG) test. Currently, only a few studies report pre- and postoperative TUG test assessments in patients with lumbar spinal stenosis (LSS).METHODSA prospective two-center database was reviewed to identify patients with LSS who underwent lumbar decompression with or without fusion. The subjective functional status was estimated using PROMs for pain (visual analog scale [VAS]), disability (Roland-Morris Disability Index [RMDI] and Oswestry Disability Index [ODI]), and health-related quality of life (HRQoL; 12-Item Short-Form Physical Component Summary [SF-12 PCS] and the EQ-5D) preoperatively, as well as on postoperative day 3 (D3) and week 6 (W6). Objective functional impairment (OFI) was measured using age- and sex-standardized TUG test results.RESULTSSixty-four patients (n = 32 [50%] male, mean age 66.8 ± 11.7 years) were included. Preoperatively, they reported a mean VAS back pain score of 4.1 ± 2.7, VAS leg pain score of 5.4 ± 2.7, RMDI of 10.4 ± 5.3, ODI of 41.9 ± 16.2, SF-12 PCS score of 32.7 ± 8.3, and an EQ-5D index of 0.517 ± 0.226. The preoperative rates of severe, moderate, and mild OFI were 4.7% (n = 3), 12.5% (n = 8), and 7.8% (n = 5), respectively, and the mean OFI T-score was 116.3 ± 23.7. At W6, 60 (93.8%) of 64 patients had a TUG test result within the normal population range (no OFI); 3 patients (4.7%) had mild and 1 patient (1.6%) severe OFI. The mean W6 OFI T-score was significantly decreased (103.1 ± 13.6; p < 0.001). Correspondingly, the PROMs showed a decrease in subjective VAS back pain (1.6 ± 1.7, p < 0.001) and leg pain (1.0 ± 1.8, p < 0.001) scores, disability (RMDI 5.3 ± 4.7, p < 0.001; ODI 21.3 ± 16.1, p < 0.001), and increase in HRQoL (SF-12 PCS 40.1 ± 8.3, p < 0.001; EQ-5D 0.737 ± 0.192, p < 0.001) at W6. The W6 responder status (clinically meaningful improvement) ranged between 81.3% (VAS leg pain) and 29.7% (EQ-5D index) of patients.CONCLUSIONSThe TUG test is a quick and easily applicable tool that reliably measures OFI in patients with LSS. Objective tests incorporating longer walking time should be considered if OFI is suspected but fails to be proven by the TUG test, taking into account that neurogenic claudication may not clinically manifest during the brief TUG examination. Objective tests do not replace the subjective PROM-based assessment, but add valuable information to a comprehensive patient evaluation.
Using International Ranks and Business Activity Indicators for Economic Development Forecasting
Authors: Puhachova M. V. 
Published: May 2019

The majority of countries use several well-known integral indicators for economic forecasting purposes, on which basis these countries’ ranks in the global economic community are computed. Apart from allowing investors to make investment decisions, such indicators and ranks help in forecasting economic development in forthcoming periods. The best known of them is Ease of Doing Business Index and Global Competitiveness Index.
The less known ones are indicators of Business Tendency Surveys (BTS), computed on the basis of data obtained from questionings of enterprise managers in various economic sectors and from studies of consumer sentiments. Yet, specialists tend to use the data from these conjuncture surveys to analyze the current economic situation in a country (total or by industry) and build short-term forecasts.
Apart from the survey indicators depicting quite clearly a situation in the economy, the most popular ones in Europe are Confidence Indicators for enterprises by economic activity, and Economic Sentiment Indicator incorporating the indicators from BTS of enterprises and consumer sentiments. These indicators are computed by the European Commission for EU member countries on monthly basis.
The article shows changes in Doing Business ranks for selected EU member countries and Ukraine. BTS indicators for industrial enterprises (estimate of production capacities; estimate of change in the production orders; estimate of the competitive position of enterprises at the internal market) are analyzed for some of these countries. A comparison of the dynamics of production capacities utilization, business confidence indicators and Doing Business rank is made for Ukraine and Bulgaria. The prognosticating capacities of BTS indicators compared with Doing Business indicator are analyzed.

Background: The existing treatment for Osteoarthrits (OA) is symptomatic by NSAIDS are effective for reducing pain associated with OA, they do not reverse the disease. This makes way for the emergence of nutraceuticals like collagen peptide which are chondroprotective in nature.
Objectives: To assess the prevalence of knee OA, efficacy of combination of collagen peptide, aceclofenac and paracetamol against aceclofenac and paracetamol alone in the treatment of osteoarthritis, the medication adherence and drug related problems in OA.
Methods: A prospective observational study was carried out in the outpatients of Department of Orthopaedics, BMCH & RC and Ambarish’s Clinic, Chitradurga. A total of 154 patients suffering from OA were identified. 60 subjects of Grade I knee OA were selected for the study from 112 cases of knee OA. The subjects were divided in two groups; Group A comprised of 30 subjects who were treated with collagen peptide, aceclofenac and paracetamol (Acetaminophen) for a period of two months, with a follow up of one month and the therapy was assessed by Visual Analogue Scale(VAS). Whereas Group B of 30 subjects who were treated with aceclofenac and paracetamol for two months with a follow up of one month and assessed by VAS.
Results: The prevalence of knee osteoarthritis was found to be 72.72%.Among them Grade I was 77.67%. From this 60 patients were selected for further study of which 90% were females and 10% males. At the end Group A showed better results than Group B. Acetaminophen and Aceclofenac related gastrointestinal disturbances were found in both the groups. Majority of the patients also had good medication adherences.
Conclusion: The study identifies and supports the use of collagen peptide to provide symptomatic relief and can be used as adjunct therapy for OA management.

Gas turbine engines processes mathematic simulations are widely used in different steps of its living cycle. All engine simulations may be divided into different difficulty levels: higher simulation level allows doing a more pre­cise description of physical processes in main units of gas turbine engines and their elements. It gives the oppor­tunity for getting better arrangement of calculation results and experimental data, reduce the quality of factors, which are traditionally used in determine engine operational characteristics with 1-level models.The purpose of the article is to describe the thermogasdynamic parameters and maintenance perfomances cal­culation method, which based on second level mathematic simulation. Its main feature is blade-to-blade turbomachines description (multistage compressor and multistage cooling gas turbine), which allows to take into account blade and flow path geometrical parameters. Their changing during the gas turbine engine design and de­velopment processes influence its performances: thrust, fuel consumption, efficiency as functions of values of flow rate, rotational speed, engine entrance conditions and so on. All these dependences could be defined by using proposed calculation method.In distinction from methods which are noted, this method allows to concede compressor or turbine incidence angles, drag values, pressure ratio, surge margin in design and off-design engine regimes. The opportunity to take into account by-passing and air bleeding from compressor blade channels and their engine parameters influence is very important also.The article includes calculation method main points, block-scheme, equations system, which gives the opportunity of alignment the engine units and their elements in wide range of state working regimes. Set of equations consists of flow rate balance equations through the stages of multistage compressor and turbine, combustion chamber and connected channels. Also system includes power balance equations, by-passing, air bleeding from compressor stages channels, its admission into the cooling turbine stages and ac­counts their thermodynamic parameters. Compressors and turbines maps parameters are calculated with main turbomachinery theory lows and semi-empirical dependences.This article is the first in series of articles, which considers this problem

The processes of gas turbine unit inlet air cooling with generation of condensate as a subproduct were investigated. The heat-humidity processes in the two-stage air cooler of combined type with the first low temperature cooling stage were water with temperature of about 7 °C as a coolant for precooling air from the changeable ambient temperature to the temperature not lower than 15 °C is used and low temperature cooling stage with a refrigerant boiling at the temperature of 2-4 °C as a coolant for further deep cooling air to the temperature of about 10 °C by utilizing the exhaust gas waste heat in the absorption lithium-bromide chiller as the high temperature cooling stage and refrigerant ejector chiller as the low temperature cooling stage of the combined thermotransformer has been analyzed for daily changing ambient air temperatures and heat loads on the stages as consequence. The processes of generating the condensate as a subproduct of gas turbine unit intake air two-stage cooling were simulated by using the computer simulation programs of the firms-producers of heat equipment for more than twice decreased heat load upon the high temperature cooling stage as compared with a heat load upon the low temperature cooling stage. The data about amount of condensate extracted in each air cooler stage was summed up over a day, three days and July and its temperature was calculated. The results of calculation have shown that the temperature of condensate received in the refrigerant low temperature cooling stage are lower by about 4 °C as compared with its value for high temperature cooling stage with a chilled water temperature of 7 °C from absorption lithium-bromide chiller. It was also shown that inspite of intensive changeable current temperatures of condensate from each and both stages mean weighted values of temperature of condensate from both stages of a combined two-stage air cooler remained nearly unchangeable during days. A conclusion about using the condensate from low temperature cooling stage as a coolant has been made

El artículo ofrece evidencia del estudio de los efectos de la aplicación de las Normas Internacionales de Información Financiera (NIIF) en la cuenta de inventarios de la Pontificia Universidad Católica del Ecuador Sede en Ibarra (PUCE-SI). La investigación de tipo documental usó el método analítico - sintético para el estudio del ejercicio económico del año 2015, año en el que se aplica por primera vez las NIIF en dicha Universidad. Las normas establecen un mismo lenguaje financiero, lo que facilita la comparación de la información entre diferentes países. Una de las cuentas afectadas por la adopción de estas normas es la cuenta inventario, se modificará el procedimiento para la valuación de inventarios como es el costo de adquisición, repercutiendo directamente en el patrimonio de las Instituciones de Educación Superior (IES). Con la aplicación de estas normas, igual que sin ellas, las IES están exentas de generar utilidades y del pago anual del impuesto a la renta. La NIC 2 (Norma Internacional de Contabilidad) (parte de las NIIF) no admite la valoración de inventario por el método “últimas en entrar primeras en salir” (LIFO por sus siglas en inglés) sino, el método para la valoración de inventarios “promedio ponderado”. Con este método, las cuentas que estaban consideradas como gasto en el ejercicio económico de 2014 afectó a la cuenta resultados de años anteriores, reflejándose en el patrimonio de la institución según el período objeto de análisis (2015). En este periodo se realizaron los ajustes respectivos para determinar estos cambios.

El testimonio único de la víctima en el proceso penal desde la perspectiva de género
Authors: Ramírez Ortiz José Luis 
Published: May 2019

<p>El autor de este trabajo analiza qué puede aportar la perspectiva de género en el proceso penal en los supuestos de declaración de la víctima como prueba única. Alcanza la conclusión de que en la fase de enjuiciamiento su valor epistémico, suministrando nuevas máximas de la experiencia que permiten valorar las pruebas sin prejuicios, no puede subsanar la insuficiencia de un medio probatorio sobre cuya base, cuando no se encuentra corroborado, no puede entenderse válidamente desvirtuada la presunción de inocencia. No obstante lo cual, destaca que, en estos casos, en la fase investigativa la perspectiva de género adquiere una notable utilidad heurística, tanto para construir adecuadamente las hipótesis inculpatorias como para buscar otras fuentes que sirvan para corroborar el testimonio en el futuro juicio oral. </p>

Published: May 2019

Background: Acetylsalicylic acid (ASA) generically known as Aspirin is an analgesic, antipyretic, anti-inflammatory and also an antiplatelet drug. In order to avoid excessive bleeding and to be on the safer side, dentists have traditionally advised their patients to stop taking aspirin before extraction of teeth although this surgical procedure can be done without cessation of aspirin intake.
Objective: The purpose of the study was to assess the necessity of interrupting aspirin therapy prior to dental extraction.
Materials and Methods: A cross sectional study was conducted in November 2015 at outpatient department of dentistry, BIRDEM Hospital, Dhaka. Sample of 50 patients who took low dose aspirin (75mg) once daily were purposely selected for this study. The blood pressure of all the subjects was recorded preoperatively. The extractions were done atraumatically under local anesthesia using 2% lidocaine with 1:100,000 epinephrine. A gelatin sponge piece was placed in socket and closed by atraumatic silk. The subjects were instructed to apply pressure pack with sterile gauze for 30 min. Evaluation was done in every 10 minutes for 30 minutes.
Results: Among 50 patients, 82.0% patients were suffering from IHD. Simple extraction was done in 92.0% of patients while the remaining extractions were done surgically. 68% was managed by pressure pack and gelatin sponge while 26.0% were managed by pressure pack only. According to Post-extraction bleeding, it was found that the bleeding time was 10 min in case of 94% patients while only 2% showed 30 minutes of bleeding time.
Conclusion: The study revealed that it is not necessary to alter or stop aspirin therapy and local hemostatic measures are sufficient to control bleeding. Therefore it can be assumed that extraction can be done without cessation of low dose aspirin and avoiding the life threatening issues.

A 15 year old boy was presented with pain in his upper anterior teeth. On clinical examination both the maxillary central incisor revealed slight discoloration and fracture of the crown. Radiographic evaluation revealed open apex of the left central incisor and apex of the right central incisor was fully developed. Apexification with MTA apical plug was carried out in left central incisor and conventional root canal treatment was done in right central incisor. In two months follow up both the tooth were clinically and radiographically asymptomatic and the healing of the apical area of the left central incisor was continued. These finding suggests that MTA can induce formation of apical barrier in the case of non-vital tooth with open apex.

Choledochal Cyst pada Anak Umur 8 Bulan
Authors: Gunarti Hesti 
Published: May 2019

Choledochal cyst is a dilatation of extrahepatic billiary duct with or without intrahepatic billiary duct dilatation. The main diagnostic tool for detection of a choledochal cyst, especially in childhood, is ultrasonography. In adults, computed tomography can confirm the diagnosis; however, endoscopic retrograde cholangiography (ERCP) or magnetic resonance cholangiopancreaticography (MRCP) is the most valuable diagnostic methods and can accurately show cystic segments of the biliary tree.We reported an eight months-old child with jaundice, anemia, tea-like urine, and damp feces. She underwent ultrasound examination which was interpreted as choledocal cyst and confirmed by CT of the abdomen. The patient later went to surgery, however she died of septic shock.
