AbstractDepression is the most frequent mental health problem in older age with serious consequences on personal, interpersonal and social level. The aim of this study was to determine the association of demographic factors, socio-economic factors and health status characteristics, with the presence of depressive symptoms in the elderly persons. The survey was conducted as a part of the national study “Health Survey of the Serbian population” in 2013. Data on the population aged 65 years and over were used for the purposes of this study (3540 respondents). PHQ-8 questionnaire was used to assess the presence of symptoms of depression. The relations between the presence of depressive symptoms, as a dependent variable, and a set of independent variables was examined by univariate and multivariate logistic regressions. Depression (PHQ-8 score≥10) was registered in 10% of the population aged 65 and above, wherein it was statistically significantly higher in women (12.7%) than in men (6.5%). Limitations in performing of daily activities showed to be the strongest predictor of depression in the elderly, while respondents who have had serious limitations had even six times more chanse to develop depression (OR=6.84). Respondents who rated their health as “bad or very bad” for 49.5% more frequently manifested depressive symptoms compared to those who evaluated their health as “very good or good” (OR=3.49). Respondents who have had two or more chronic diseases were three times more likely to have depression (OR=3.1) compared to people without chronic disease.
A Poética Estética da Memória em Valsa com Bashir
Authors: Capelatto Igor Alexandre , Lyra Carla 
Published: October 2018

Este presente artigo tem como ponto de partida o filme Valsa com Bashir de Ari Folman para uma reflexão sobre a estética do documentário de animação como ferramenta de construção de história, política e memória. De acordo com o release oficial (DVD e BLURAY), o diretor Ari Folman, que participou como soldado da segunda guerra do Líbano em 1982, examina suas próprias culpas para abordar os problemas da reconstituição da memória dos episódios dramáticos que culminaram no massacre dos campos de Shabra e Shatila, em que teriam morrido 3.000 refugiados palestinos. Com o fato da imagem fotográfica das câmeras não ‘darem conta’ de representar a memória em si, Folman recorrerá ao desenho, segundo o autor, como estética capaz de acionar memórias que a fotografia não é capaz de alçar.

Authors: Dzhamankulova F S , Musuraliev M S , Sorokin A A 
Published: October 2018

Aim. To estimate the value of different maternal risk factors to develop a prognostic model for prevention of fetal congenital anomalies.
Methods. A prospective complex clinical and laboratory and functional examination of 629 pregnant women with fetal congenital anomalies and 206 pregnant women without fetal pathology was conducted with a comparative assessment of the medical and social risk factors for congenital defects. To build a predictive model for prevention of congenital anomalies, the logistic regression method was used.
Results. According to static analysis, significant medical and social risk factors for congenital anomalies are acute respiratory viral infection with fever in early gestational age (OR=20.0, 95 % CI: 2.756-145.7), the absence of prophylactic folic acid (OR=15.16, 95 % CI: 7.35-31.31), polyhydramnion (OR=14.2, 95 % CI: 4.453-45.18), oligohydramnion (OR=3.258, 95 % CI: 1.382-7.679), preeclampsia (OR=3.51, 95 % CI: 1.11-8.96) and maternal anemia (OR=4.75, 95 % CI: 2.51-8.99). As a result, we received the predictive model with high sensitivity equal to 0.924, specificity 0.655 and Sommers’ D 0.629. Nagelkerke’s R square of the model was 0.552 (moderate). This means that the model explains 55.2 % variation of the dependent variable.
Conclusion. The conducted study allowed identifying the predictors affecting the development of congenital fetal anomalies, and the developed predictive model for determining the probability of congenital fetal anomalies in the early antenatal period is characterized by high sensitivity and can be suggested for the use during the monitoring phase of the pregnant woman in the outpatient setting.

Aim. Evaluation of the awareness of health workers of vaccine prevention at the present stage.
Methods. To achieve the aim, survey of health workers of the Republic of Tatarstan was conducted using the developed questionnaire. The coverage of survey was 3 250 people. Statistical processing of the results was carried out using Microsoft Excel 2010 programs.
Results. The conducted study revealed that a significant proportion (95 %) of health workers were positive about vaccine prevention, were vaccinated themselves and vaccinated their children. The most prevalent forms of informing parents of vaccinated children about adverse reactions after vaccination are oral recommendations by the doctor and information sheets about adverse reactions. The majority of interviewed health workers (89.9 %) support the initiative to cancel the right of citizens to refuse vaccination. In the opinion of health workers, the main components of successful organization of vaccine prevention in the medical organization are availability and diversity of vaccines, the level of qualification of medical personnel, and equipment of the vaccination room. Less than half of health workers were trained in specialized training on immunoprevention. The majority of health workers (86.3 %) consider it necessary to expand the national schedule of preventive vaccinations of the Russian Federation.
Conclusion. Organizational measures to inform health workers in various areas of vaccine prevention are needed to be taken; promising directions are organizing specialized courses on immunoprevention and discussion of relevant aspects of immunization of the population and adverse reactions in post-vaccination period.

Aim. The assessment of quality of diagnosing acute poisoning by ambulance paramedics.
Methods. Retrospective analysis of the rate of diagnostic discrepancies and undifferentiated diagnoses in 1 242 patients delivered by ambulance paramedics of Kazan to the hospital with the diagnosis of acute poisoning.
Results. Referral diagnosis of acute poisoning among patients delivered by ambulance paramedics to the diagnostic department of the hospital was not confirmed in 792 cases, among which in 683 cases admission was not needed due to the absence of indications. Among refusals of hospitalization the majority of patients (70.8 %) were in the state of intoxication of various etiologies and healthy patients. In 8.5 % of cases of diagnostic discrepancies of acute poisoning paramedics delivered to the hospital patients with severe urgent somatic pathology - urosurgical, neurological, surgical, therapeutic, etc. The rate of diagnostic discrepancies in the group of alcohol, drug, undefined substances and mushroom intoxication was higher - 71.5 %, than in the group of medication and carbon monoxide intoxication - 39.7 %. In poisoning with impaired consciousness a direct dependence of the rate of diagnostic discrepancies on the rate of impaired consciousness was observed. The rate of undifferentiated diagnoses in the first group of poisoning was also higher - 82.3 %, than in the second group - 45. 8%, but no dependence on the impairment of consciousness was observed among patients.
Conclusion. High rate of diagnostic discrepancies (63.8 %) and undifferentiated diagnoses (71.1 %) are the consequence of lack of competence in medical toxicology among ambulance paramedics. In 98.2 % of cases, the probable etiological diagnosis of the disease, suspected as acute poisoning, in the study group of patients could be diagnosed using diagnostic methods available for paramedics.

Published: October 2018

Forests are known to play an important role in regulating the global climate. Nowadays, especially in developing countries wide spread deforestation and forest degradation is continuing unknowingly ad deliberately. This study was conducted to estimate carbon stock in undisturbed research section (Dikolo Penisula) of Bimbia Bonadikombo Community Forest (BBCF). Three transects were created in the research plot and fifteen plots of 10m x10m were laid systematically along each transects, and five sub plots of 1m x1m quadrats were laid within 10m x10m i.e. at the four corners and middle. Trees data (DBH≥2.5cm and Height) were measured in the 10x10m plots. Soil, litter herbs and grass data were collected in the 1x1 m plots. The litters, herbs and grass (LHG) were weighed on the field and evenly mixed and dried at 650C, to determine dry biomass and percentage of carbon. Soil samples were collected at 30cm depth (between 0-10, 10-20, 20-30 cm depths) and density cups was used to determine bulk density and percentage (%) of organic carbon concentration. Allometric equations was use to obtain trees biomass and carbon stock. The results revealed that the total carbon stock was 38.61 t·ha-1. The Soil organic carbon (SOC) was 33.9 t·ha-1 that is 87.8%, while the forest trees stored 2.91 t·ha-1 that is 7.5% of the total carbon. LHGs biomass contributed only1.82t·ha-1 of carbon that is 4.7% of the total carbon stock. The result shows that BBCF is a reservoir of high carbon. To enhance sustainability of the forest potentiality, the carbon sequestration should be integrated with reduced emission from deforestation and degradation (REDD+) and clean development mechanism (CDM) carbon trading system of the Kyoto Protocol to get monetary benefit of CO2 mitigation.
The Effect of Depression on Patient-Reported Outcomes After Total Joint Arthroplasty Is Modulated by Baseline Mental Health
Authors: Halawi Mohamad J. , Cote Mark P. , Singh Hardeep , O’Sullivan Michael B. , Savoy Lawrence , Lieberman Jay R. , Williams Vincent J. 
Published: October 2018

Background:
Depression and poor mental health are known to be negative predictors of patient-reported outcomes after total joint arthroplasty. Although previous studies have examined these risk factors in isolation to each other, they are, in reality, closely related, and yet each represents a different aspect of one’s psychological well-being. The objective of this study was to investigate the association between depression and patient-reported outcomes, taking into account patients’ baseline mental health.

Methods:
Our prospective, institutional joint registry was queried for patients who had undergone primary elective total joint arthroplasty and had a minimum follow-up of 1 year. Baseline mental health was measured by the Short Form-12 Mental Component Summary (SF-12 MCS). Four cohorts were analyzed on the basis of the presence or absence of depression and patients’ SF-12 MCS scores at the time of the surgical procedure, which were categorized as either poor or good on the basis of previously defined cutoffs. The primary outcomes were the net changes in SF-12 MCS, SF-12 Physical Component Summary (PCS), and Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) scores at 4 and 12 months postoperatively. Univariate and mixed-effects model analyses were performed to control for potential confounding factors.

Results:
Patients with depression but good baseline mental health achieved gains in patient-reported outcomes that were comparable with those of normal controls (p > 0.05). Patients with poor baseline mental health achieved significant gains in all patient-reported outcomes, but the changes were largest for those without depression (p < 0.05). Only patients with depression and poor baseline mental health did not cross the threshold for good mental health at the time of the latest follow-up despite achieving similar gains in physical function compared with their counterparts who did not have depression.

Conclusions:
The effect of depression on patient-reported outcomes is more complex but less pessimistic than previously thought. Patients with depression undergoing total joint arthroplasty may have significant improvements in their patient-reported outcomes, but the net gains are modulated by their mental health at the time of the surgical procedure. Preoperative screening of patients with depression using the SF-12 MCS may help to identify those who are at risk for attaining suboptimal patient-reported outcomes and may benefit from counseling or psychiatric referral for optimization before undergoing a surgical procedure.

Published: October 2018

Summary
The safe and economical determination of a wellbore trajectory in directional drilling is traditionally achieved by measurement-while-drilling (MWD) methods, which implement magnetic north-seeking sensor packages. Inaccuracies in the determination of well path arise because of random and systematic errors in the measurements of the sensors. Multistation analysis (MSA) and magnetic in-field referencing (IFR) have already demonstrated the potential to decrease the effects of errors because of magnetization of drillstring components along with variable errors caused by irregularities in the magnetization of crustal rocks in the vicinity of wells. Advanced MSA methodologies divide a borehole into several sections and use the average reference values of the total magnetic field, declination, and dip angle for analysis of errors in each section. Our investigations indicate that the variable-reference MSA (VR-MSA) can lead to a better determination of errors, specifically in areas of high magnetization. In this methodology, magnetic reference values are estimated at each station using forward and inverse modeling of surface-magnetic observations from IFR surveys. The fixed errors in magnetometer components are then calculated by minimizing the variance of the difference between the measured and unique estimated reference values at each station. A Levenberg-Marquardt algorithm (LMA) is adopted to solve the nonlinear optimization problem. Examination of this methodology using MWD data confirms more than 20% improvement in well-path-determination accuracy by comparing the results with the corrected path from the conventional MSA method and gyro surveys.

Published: October 2018

Abstract
Shale gas usually distributes in dense porous media reservoirs, which is not easy to develop without external force. Hydraulic fracturing has been an effective technology utilized to improve the yield of shale gas. However, the performance of this method depends on large displacement and liquid volume, resulting in the blockage of the flowing channels in the reservoir and huge waste of water resources. Thus, it is particularly important to increase the rate of fracturing fluid return.
The contact angle test, owens two-liquids method and spontaneous imbibition were conducted to investigate the effect of gas-wetting alteration on the shale wettability and liquid flow. Moreover, the energy dispersive spectroscopy was used to analyze elemental changes on the shale surface.
The results showed that the contact angles of water and n-decane on the shale surface increased from 36o and 0o to 128o and 115o, respectively. The surface free energy rapidly reduced from primeval 71 mN/m to 5.6 mN/m after treated by 0.4 wt.% gas-wetting reversal agent. The results were further verified by spontaneous imbibition. The analysis of energy dispersive spectroscopy (EDS) indicated that the gas-wetting reversal agent could product adsorption layer on shale surface, which played an important role in super gas-wetting.
The wettability of shale surface could be reversed from liquid-wetting to super gas-wetting by the novel gas-wetting reversal agent with double-chain hydrophobic and olephobic structure, which could significantly enhance the flowback rate of the fracturing fluid due to super gas-wetting alteration.

Published: October 2018

Abstract
Despite decades of numerical, analytical and experimental researches, sand production remains a significant operational challenge in petroleum industry. Amongst all techniques, analytical solutions have gained more popularity in industry applications because the numerical analysis is time consuming; computationally demanding and solutions are unstable in many instances. Analytical solutions on the other hand are yet to evolve to represent the rock behaviour more accurately.
We therefore developed a new set of closed-form solutions for poro-elastoplasticity with strain softening behaviour to predict stress-strain distributions around the borehole. A set of hollow cylinder experiments was then conducted under different compression scenarios and 3D X-Ray Computed Tomography was performed to analyse the internal structural damage. The results of the proposed analytical solutions were compared with the experimental results and good agreement between the model prediction and experimental data was observed. The model performance was then tested by analysing the onset of sand production in a well drilled in Bohai Bay in Northeast of China. Acoustic and density log along with core data were used to provide the input parameters for the proposed analytical model in order to predict the potential sanding in this well. The proposed solution predicted the development of a significant plastic zone thus confirming sand production observed by today sanding issue in this well.

Published: October 2018

Abstract
Fixed plane perforation technology is regarded as a good mean to address near wellbore tortuosity and reduce breakdown pressure in low permeability reservoirs. To better understand of the fracture behavior in wellbore perforations at the defining plane, a 2D finite element model has been implemented in ABAQUS to investigate the effects of mechanical, perforation and treatment parameters on hydraulic fracture propagation path. The global zero thickness cohesive elements have been inserted into numerical model, thus the existence of natural fractures on patterns of fracture propagation can be considered in this model. It shows that there is a great impact of natural fracture on the fracture propagation path. Moreover, the fracturing fluid viscosity, pumping rate, in-situ stress and perforation parameters also play critical roles on fracture propagation. Comparisons of numerical simulations show that the effects of the stress anisotropy, pumping rate, fluid viscosity, Young's modulus, Poisson's ratio and perforation intersection angle on the hydraulic fracture geometry of exterior fractures and interior fracture at the defining plane are different. It found that the width of interior fracture is almost zero at the near wellbore zone at the end of pumping which induced by the stress interference of neighboring fractures in some cases, thus perforations design at the defining plane must be carefully considered. Additionally, in most cases, hydraulic fractures from exterior perforations tend to propagate upward and downward simultaneously. Although hydraulic fractures initiated from a perforation that misaligned with the direction along the maximum in-situ stress initially at short distance, hydraulic fractures would finally reorient itself to the maximum in-situ stress direction, thus increase chances of creating one simple transverse fracture along maximum in-situ stress orientation. Because the strong stress interference of competing fractures, the possible breakdown of casing and perforation tunnels should be considered before well completion. The simulation results from this study offer some insights to enhance fixed plane perforation design for hydraulic fracturing treatments.
