Characterizing Water Breakthrough Using Analytical Diagnostic Workflow
Authors: Dokhon Waleed , Alkayadi Fatimah , Dallag Mohammed
Published: January 2020

Water management has always been a challenge especially in mature fields. Consequently, mechanical, chemical shutoff and other water reduction techniques have been developed and deployed to curb the menace in the hydrocarbon industry. However, poor diagnostic work can be a leading reason for the low success rate for any water control method. This paper introduces a holistic workflow to understand the candidate selection, filter the wells based on priority and determine the water breakthrough mechanism to eventually select the optimal remedial action.

In this paper, 7 wells are selected and prioritized to undergo a workflow to diagnose water breakthrough and characterize it. The first analytical tool is Chan correlation, which incorporates the water-oil ratio for determining the water signature. For determining the water entry zone, Production Logging Tool (PLT) will be used as the second investigative tool. Water source identification plays another major role in assessing whether the water is coming from an aquifer, nearby injector or native reservoir fluid, which can be determined by the frequent sample collection and lab analysis for ionic concentration. These three investigative tools will provide a basis to select the proper water management strategy.

The results of the diagnosis have revealed several facts regarding the aforementioned parameters. A number of the diagnosed wells have shown a steep increase in oil-water ratio and oil-water ratio derivative, which hints to a possible nearby thief zone according to Chan correlation. Reviewing the produced water ionic concentration suggests low salinity and that the water's chemistry is closer to that of an injected water than reservoir water. Finally, Production Logging Tool showed multiple water entries in the open hole section. According to the diagnosis, Inflow Control Device deployment for those wells are recommended. Couple of multilateral wells completed with Inflow Control Valves (ICV) showed rapid channeling of water, which can be caused by a thief zone or a lateral dominating the flow and contributing high water cuts. These wells were subjected to ICV optimization and it confirmed that a latera was dominating the flow with high water cut and was optimized. The water cut for those two wells dropped by 58%.

The workflow enables engineers to understand the water breakthrough mechanism in a timely-matter, which allows them to categorize the wells based on the different water signatures such as water coning, thief zone, and near wellbore breakthrough. The proposed workflow can be adopted and adjusted based on the water management problems associated to any field in order to find the optimal remedial action. This outcome played a role in the planning of placing and drilling new wells in the field.

Published: January 2020

The workflow for waterflood conformance improvement in a naturally fractured carbonate reservoir with polymer gel injection is presented. The workflow outlines a systematic way of identifying the conformance candidates and evaluating optimal gel volume for the job design predicated on using the regular surveillance data as well as a novel way of gel characterization with lab measurements. Economic and technical success of conformance jobs is based on successful implementation of the improved workflow demonstrated in this work. The wells in the carbonate reservoir of interest are screened for conformance issues using only the injection and production data. Using a set of Chevron analytical tools with the field injection and production data, we screened over four hundred wells and selected four candidate injectors with the most severe water cycling issue in the carbonate reservoir of interest. Inter well tracer test was part of the pilot to assess the effectiveness of the workflow by verifying the correct candidate selection and designed gel volumes by quantifying the thief zone volumes. Lab extrusion tests of selected mature polymer gels also demonstrated that the flow capacity of an open fracture could be reduced up to 4000 times even after ruptured by continuous water injection at the right concentrations. After the tracer tests confirmed the severe conformance issues for the selected injectors, conformance treatment was designed for optimum concentration using the lab results and optimal volume using the tracer interpretation. Finally, the first gel injection pilot is executed, and appropriate surveillance plan implemented to evaluate the results. During pilot execution injection pressure, polymer concentration and volumes were closely monitored. The offset producers were tested frequently as part of the surveillance plan. The analysis of the injection and production data shows positive response with more oil production for each barrel of water injection in all four treated patterns. This work exhibits a systematic approach of polymer gel injection for waterflood conformance improvement from candidate selection to lab tests for selection of the most appropriate chemical agent to field execution. The objective of this work was to establish criteria for more efficient and economic gel conformance treatments with high success rate in the carbonate field of interest.
Effect of Injection Rate on Oil Water Relative Permeability Accounting for Capillary Pressure and Outlet end Effects
Authors: Almutairi Abdulmajeed , Le-Hussain Furqan
Published: January 2020

Two-phase immiscible drainage experiments are performed on strongly water-wet sandstone sample to assess and illustrate capillary end effects at different rates on relative permeability. All the experiments were done under unsteady state conditions with oil displacing brine in fully brine saturated cores. First, relative permeability curves are calculated using the Johnson–Bossler–Naumann (JBN) method (Johnson et al. 1959). Then, modified JBN model is defined to account for capillary pressure. Lastly, numerical simulator is used to generate relative permeability curves based on history matching. Results of the experiments show that as the rate increases (higher capillary number), the water relative permeability increases while the irreducible water saturation decreases. With high rate, less water saturation is being accumulated at the outlet hence less irreducible water and higher relative permeability. Moreover, the oil relative permeability curves are getting higher with higher rates confirming CEE impact on the tests. The calculated irreducible water saturation based on the core weights re-affirms the JBN calculation and decreases with higher rates. This paper proves capillary end effects on relative permeability curves at low rates which have low capillary numbers on water-wet sandstone cores.
Synthetic Time-Lapse Production Surveillance: Automated Workflow Technology to Monitor Oilfields Continuously and on Demand
Authors: Dallag Mohammed , Bawazir Mustafa , Shukla Sourabh
Published: January 2020

One goal for oil fields of the future is acquiring continuous and on-demand data as required for field and reservoir management. Synthetic time-lapse production methods are becoming a way of providing this information at and away from wells. Time-lapse production log data acquired over oil fields is used to monitor water sweep in the reservoir. Production logs provide a direct measure of the fluid flowing downhole and detect the unwanted fluid entries. In field applications, this advanced scanning of fluid profiling successfully derisked several infill well locations and identified new workover candidates and drilling opportunities in the fields.

Synthetic time-lapse production logging is a useful complement to understanding reservoir heterogeneity and complexity through tailored synthetic and real data integration. A computer-based workflow has been developed to automate the downhole production flow profile. Production performance of the well is assessed, considering the dynamic time-lapse logging data. A synthetic flow profile is constructed to show the change in water production signature, and the well is further examined if it undergoes remedial actions. Reservoir characterization is a continuous process during the life of the oil field. As new data are available, the model is updated and contains more details. The incorporation of all data allows increased accuracy and reduced uncertainty in characterizing the reservoir.

The proposed methodology requires the acquisition of dynamic production logging data to establish a solid workflow and validate the model. Uncertainty can be eliminated with the acquisition of additional production logs. Recommendations for improvement of the current well condition can be made to reduce the well water cut and improve oil production from the well. Consequently, well classification and candidate selection for workover can be achieved. The results of this work demonstrate the strength of applying multidisciplinary team efforts to develop automated workflows that are relevant to reservoir and production engineers who deal with complex reservoirs with numerous wells.

An integrated approach was applied for production enhancement of the upper and lower shaly sandstone reservoirs of the Ignalinsky and Tympuchikansky fields in the Leno-Tunguska oil and gas province of the East Siberian Basin, Russia. The approach includes both comprehensive laboratory studies and a direct strategy of hydraulic fracturing design, as well as solutions to obtain optimum well performance. The approach can be implemented in future prospects and can form part of the strategy for future development in the region.

Extensive laboratory research was performed to select the proper fluid for proppant transport that could withstand all the complicated terrigenous conditions within the fields. One of the main challenges was rheological suitability of the fluid at low reservoir temperatures. The laboratory studies were important for identifying the best fluid for fast fracture cleanup while optimizing the sand-carrying capacity of the fracturing fluid. The hydraulic fracturing design incorporated calibrated petrophysical and geomechanical analysis with actual fluid rheology characterization taken from laboratory test results.

The laboratory work confirmed that the reservoir rock was water sensitive, with a significant presence of clay minerals including kaolinite, montmorillonite, and montmorillonite mixed with illite. A new generation of clay stabilizer was used to address this sensitivity. In addition, an enzyme breaker was used with the objective of effectively breaking the fracturing fluid at low reservoir temperatures. The fracturing operations that were performed during two winter campaigns resulted in high starting and operating production rates. The treatment designs incorporated a linear gel pre-pad stage prior to the crosslinked pad stage in an effort to extend fracture half-length while reducing the risk of the fracture growing in height into overlying gas-saturated layers. The results of the design efforts were analyzed using logging and fracture treatment data, which demonstrated that the design was effective in avoiding the gas-saturated formation. Overall, 23 hydraulic fracturing operations were done in five wells at Ignalinsky and Tympuchikansky fields for the B10 and B13 formations. Production results were analyzed, and further optimization paths were identified.

The study breaks new ground in enhancing the hydrocarbon extraction from low-temperature shaly sandstones with mixed wettability, not just with terrigenous reservoirs within the above-mentioned fields, but also with other reservoirs of a similar geological context, primarily the Leno-Tunguska oil and gas province of the East Siberian Basin, Russia. This is especially important in view of the depletion of oil reserves in Western Siberia and the growing interest in the development of hydrocarbon fields in Eastern Siberia.
Experimental Quantification of Slickwater Proppant Transport in Subsidiary Hydraulic Fractures
Authors: Alotaibi Msalli , Miskimins Jennifer L.
Published: January 2020

Hydraulic fractures created by slickwater fluids are commonly known for generating fracture network complexity, which presents a challenge for the associated proppant transport. The difficulty of proppant transport in subsidiary fractures is attributed to the velocity inside them and slickwater's low viscosity. Subsidiary fractures are believed to have lower propped area relative to the primary fracture; however, this is not quantified and its effect on proppant grain distribution is not established. This paper presents laboratory measurements of such slickwater-created propped areas in subsidiary fractures and describes the dune development mechanisms and the associated effects on grain sorting.

Experiments were conducted using a 30/70 mesh brown sand and a specially designed slot flow apparatus that has a multi-fracture network of three secondary and two tertiary fractures, in addition to the main slot. The secondary fractures were attached at 90° angles from the primary fracture and separated at equal distances.

The study results show that slickwater transports large amounts of proppant into secondary fractures, reflected by the large developed dunes areas of 40.8% of the total fracture area. Fractures closer to the slurry entry point show higher propped area than ones further away. For tertiary fractures, they developed only 4.5% of the total network propped area, indicating poor slickwater proppant transport inside them. Distinct proppant transport mechanisms were identified for the subsidiary fractures with different dune heights. This finding indicates grain size sorting and different proppant size distribution in the fracture network.

This paper presents for the first time an experimentally quantified propped area distribution by slickwater in a complex fracture network. It reveals new insights about slickwater proppant transportability into subsidiary fractures and establishes a new understanding of proppant transport mechanisms and grain size distributions in subsidiary fractures, which can have a considerable impact on hydraulic fracture conductivity estimation and, hence, productivity enhancement.
Geochemical Analyses and Lab Data Corrections in Jurassic Carbonate Source Rock: Implications on Resource Assessments
Authors: Al Eid Ali , Biollo Jerome , Duque Fabian , Hakami Ahmed
Published: January 2020

An intrashelf depo-center hosts the Jurassic carbonate source rock, which contains one of the richest hydrocarbon producing source rock intervals in the world. The understanding of kerogen distribution and maturity across this frontier unconventional basin is key for focused prospectivity and future development. A correlation between total organic carbon (TOC) and porosity and key reservoir parameters has been observed. The porosity, measured using the Gas Research Institute (GRI) methodology, shows a poor TOC values correlation, as measured by LECO. A substantial amount of liquid hydrocarbon has been recorded during pyrolysis in the S1 peak, constituting a significant portion of the measured TOC. This effect has to be quantified in order to avoid issues when calibrating logs to predict TOC, saturation and porosity.

An analytical workflow was developed to remove the free hydrocarbon and bitumen from samples. Each sample was split into two parts; and sent for LECO-TOC and SRA pyrolysis. The initial run was conducted using an industry standard sample preparation method. In the second run, sample preparation included a solvent extraction. An organic solvent was used to remove the free hydrocarbons and mobile bitumen, thus taking off the S1 and oil shouldering effects on the S2 emission peak on the pyrograms. The two resulting data sets were then compared, and showed a net reduction of TOC in addition to increasing in Tmax values for most of the post-extraction samples.

Results of this detailed analysis yielded a new set of thermal maturity values. Furthermore, log-derived TOC calculations have been recalibrated resulting in a more accurate petrophysical model. These corrections generated more reliable results that greatly enhanced our understanding of basin maturity variations and organic matter distribution; thus decreasing uncertainty and refining in-place resource estimations across the basin.

Objective: to characterize post-cesarean surgical site infections. Method: descriptive documentary study, performed at a hospital in southern Brazil, with forms of active search and post-cesarean stitch removal from outpatient care performed between January 2015 and December 2017. Data were cited regarding the indication of cesarean section, risk factors, drug use, culture collection and infection rate, analyzed by descriptive statistics. Results: a total of 1,479 post-cesarean outpatient care records (2015=456; 2016=487; 2017=536) were investigated, with lack of dilation as the main indication. The incidence of surgical site infection increased in the last year (2015=2.6%, 2016=2.3%, 2017=3.5%) in which the nurse was included in the outpatient clinic. Conclusion: the indication for cesarean section due to lack of dilation is not foreseen in protocols, and the increase of infection rate in 2017 might be justified by the increased vigilance.

A Rare Type of Balanitis
Authors: Duarte Bruno , Rodrigues Ana , Fernandes Cândida
Published: January 2020

Syphilis is an old disease and a major public health concern, which is re-emerging in the western world. Atypical syphi- litic presentations can be challenging to diagnose. We present a 23-year-old, HIV-positive man who has sex with men who presented with a 2-week history of an asymptomatic lesion on the glans. Previous topical and systemic treatments proved unsuccessful. Physical examination demonstrated a slightly indurated, ill-defined erythematous plaque over most of the glans. Enlarged, non-tender, bilateral inguinal lymph nodes were palpable. Serological tests revealed a fourfold increase in the VDRL titre (1:8, previously 1:2). A diagnosis of syphilitic balanitis of Follmann was made and complete resolution was achieved with an intramuscular single dose of benzathine penicillin 2.4 MU.

Syphilitic balanitis of Follmann represents an uncommon manifestation of primary syphilis, with less than 100 cases reported. Untrea- ted, it will resolve spontaneously, but the patient will remain highly infectious and at-risk for long-term morbidity. In an era in which the number of syphilis cases is increasing sharply both in Western Europe and the United States, all physicians should be aware for the typical and atypical early syphilitic manifestations as they represent opportunities of paramount importance for treatment and epide- mic control.

Published: January 2020

Introduction: Diagnostic uncertainty is an inseparable component of medical practice. The dichotomous classification of melanocytic lesions as benign or malignant has been replaced in recent years by a more flexible approach in which diagnostic uncertainty is recognized and accepted.

Methods: In order to characterize the population of melanocytic proliferations of uncertain malignant potential diagnosed at our center between 2007 and 2017, histopathological reports of melanocytic lesions classified, in this period, as either dysplastic or malignant were analyzed.

Results: Twenty-three lesions (4.3%) with borderline histopathological features or uncertain malignant potential were identified. The mean patient age was 34.8 years. Sixteen lesions (69.6%) were observed by a second pathologist. The most frequently performed treatment was wide excision. A sentinel lymph node biopsy was performed on 2 patients, both being negative. The median follow-up time was 22 months, and there was no recurrence of any treated lesion.

Discussion: The controversy of the subject extends from the nature and classification of these lesions to their treatment. In this work we perform a statistical review of the population of melanocytic proliferations of uncertain malignant potential diagnosed in our department.

Brain Injury Associated with Chronic Spontaneous Urticaria: a Kounis-Like Syndrome?
Authors: Santiago Luis , Gonçalo Margarida
Published: January 2020

‘Kounis Syndrome’ is an acute coronary artery event due to an artery spasm occurring during immediate hypersensi- tivity reactions or chronic spontaneous urticaria. Recently it has been reported in other systems, including the cerebral vasculature. We present a case series of three patients observed between January 2016 and December 2018 with acute and transient brain injury associated with concomitant exacerbation of chronic spontaneous urticaria, including one patient with multiple recurrences of neurologic symptoms during exacerbations of urticaria. Minor imaging defects were observed in two patients, but there were no apparent vascular risk factors or coagulation abnormalities that might explain neurologic symptoms.

Chronic spontaneous urticaria, through activation of mast cells and mediator release, seems capable of inducing cerebral arterial aggression. The authors want to call the attention to this possible association, reinforcing the need to keep urticaria under control to prevent neurological manifestations.

Published: January 2020

Increasing cash balance is an effort made by SME’s in its operational activities. Cash that is managed optimally can reduce excess cash so that SME’s can maximize profits. There are various ways that SME’s can implement to increase their cash balance, namely by maintaining the cash balance to be optimal and holding back cash that is incurred so as not to overdo it. To achieve this goal, SME’s must improve cash management and SME’s are expected to improve their financial performance. Things that must be avoided in carrying out business activities that can hinder in achieving the goals of SME’s are there are non-rotating cash that settles on cash. Cash that has no turnover can reduce the profits that should be obtained, so that excess cash does not fail and can be used to buy investment so that it provides more benefits to SME’s.

This study aims to be able to know and understand the condition of the cash balance and to know and understand the formation of an optimal cash balance, as well as knowing the adequacy of MSME cash flows in Kendalsari, Malang City. This type of research uses case studies, namely research using secondary data. Secondary data used in this study is the history of the establishment of SME’s, MSME financial data, and information on product intricacies. The data analysis technique in this study is to use the Orr Miller Model calculation with the aim to be able to find out the Optimal Cash Balance in SME’s. The results of the study indicate the lower limit of cash availability for SME’s in order to optimize financial performance of Rp. 107,123. Whereas the upper limit of cash should be Rp. 321,396. And the results of the cash flow adequacy ratio show a value of 1.614. Thus the results of this study can be used as a reference for SME’s in conducting cash management.

ANALYSIS Of CAPITAL ASSET PRICING MODEL ACCORDING TO SHARIAH PRINCIPLE: INDONESIAN EVIDENCE
Authors: Widianingsih Yuni Pristiwati Noer
Published: January 2020

Capital Asset Pricing Model (CAPM) is one of the estimated return models developed in conventional financial instruments that have different characteristics from Islamic financial instruments. So the CAPM model cannot be directly applied in Islamic financial instruments, so an estimation model is needed, namely the Shariah Compliant Capital Asset Pricing Model (SCAPM). This study aims to produce a SCAPM model that can be applied to estimate returns in Islamic financial instruments. The data used in the test is a list of sharia companies listed on the IDX, sharia company stock prices, Indonesia Sharia Stock Index (ISSI), yield of sukuk and return of Bank Indonesia Certificates (SBI) for the period 2010 - 2018. Testing is done by comparing expected return with the CAPM and SCAPM models. The SCAPM model used is to eliminate the risk free asset factor and replace it with inflation, zakat, and yield of sukuk. The results of the analysis using graphs and the compare mean test show that the results of the expected return with the SCAPM and CAPM models have no difference, so the SCAPM model can be used as an alternative model of return estimation in Islamic Financial Instruments on the IDX.

Arduino UNO R3 is one of the cheapest and easiest microcontroller boards that has great potential to be used as a basis for the measurement system. This study aims to develop measurement system of crude oil capacitance by using IDCs(Interdigital Capacitors). By knowing the value of crude oil capacitance, the crude oil permittivity value can be calculated. The crude oil permittivity value data is extremely needed in making crude oil heating systems using microwaves. The study used IDC sprinted on a PCB board with a copper layer as the electrode. Then, the system measurement results were compared with the results of PM 6303 RCL meter Phillip type A frequency measurement of 1 kHz which was used as reference data to determine the extent of measurement errors. From the results obtained, it is known that the error value of the Arduino UNO R3 based capacitance repeatability measurement is 0.47%. While the results of the linearity test measurement of crude oil capacitance measurement of temperature increases using the Arduino Uno-based IDCs sensor, the R2 value is 0.87. Thus it can be seen that the Arduino UNO R3-based capacitance measuring device has quite good sensor characteristics.

Taking Italy and Poland as its main case studies, this book re-examines the major political and ideological confrontations that crossed Cold War Europe from the perspective of ordinary families and of those who sought to regulate the way in which they lived. Crossing the iron curtain, and looking at two countries hardly ever brought together in historical analysis, the book shows the extent to which the battle over the regulation of family and marriage shaped the social, political and cultural landscape of postwar Europe.

Aim of the study. To determine the effect of surgical tactics on the duration of ischemic period with simultaneous combined correction of two or three valves of the heart and myocardial revascularization

Materials and methods. The work is based on the analysis of the results of single-stage multivalve correction in conjunction with coronary artery bypass grafting in 93 patients, which was performed at the National Amosov Institute of Cardiovascular Surgery for the period from 2014 to 2016. Depending on the tactical approach and the sequence of surgical procedures, patients were divided into groups. 1 – “CABG off pump and subsequent correction of heart valves” (n = 15); 2 – “Correction of heart valves and bypass grafting in conditions of cardioplegia” (n = 78).

Results. Using different approaches to achieve high-quality protection of the myocardium at the time of its ischemia, minimizing the impact of artificial circulation on the body by improving the conditions and reducing the ischemic heart time showed significant advantages of the method of pre-shunting CA in the working heart.

Conclusions.1. Correction of combined multiple valve pathology with coronary heart disease requires prolonged cardiopulmonary bypass time and ischemic heart time, which requires reliable protection of the myocardium, which is difficult to carry out in the presence of stenoses in the lumen of the CA. 2. The use of the method of preventive restoration of coronary blood flow by bypassing the spacecraft on the working heart before clamping of the aorta, has significant advantages in the duration of the cardiopulmonary bypass time and ischemic time of the heart.

Abstract.The work is devoted to the results of the study of the role of the mitral valve (MV) in the pathogenesis of hypertrophic cardiomyopathy (HCM).

Purpose. To determine the role of MV in the pathogenesis of HCM. Morphological examination was performed on the operating material: 36 MV fragments, 41 specimens of the interventricular septum resected during Ferrazzi surgery, 4 autopsy cases of aortic valve stenosis (AVS). Morphological data were compared with the results of Echocardiography: 41 patients with HCM (29 men and 12 women, mean age – 39.8 ± 15.3 years), 53 patients with AVS (comparison group), 54 healthy volunteers (24 men and 30 women, mean age – 33.2 ± 8.5 years). Echocardiograms of maximal longitudinal displacement of the basal segments of the left ventricle were analyzed. The results were processed using the Statistica 6.0 application package.

At HCM changes of MV in the form of atypical chords are attached, which are attached to the smooth part of the ante-rior flap, destruction of the endothelial layer on the ventricular surface of this flap, increase of the sizes of the flap and chord, expansion of the spongy and fibrosis of the compact layer. In the basal part of the interventricular septum a fibrous stain is formed on the endocardium. In the area of the myocardium adjacent to the mitral fibrosis stain, maximal hypertrophy of cardiomyocytes and interstitial fibrosis spreading from the fibrous stain are observed.

Asymmetric contraction of the basal segments of the LV was reported in patients with HCM with vector-echocardiogram by reducing the longitudinal displacement of the septal, inferior and anterior segments and increasing this index for the posterior and lateral walls. This indicates the asymmetric nature of the reduction of the LV myocardium, resulting in the MV fibrous ring during systole shifting unevenly. In patients with AVS, circular myocardial hypertrophy due to stenosis does not affect MV position during systole. According to the study, morpho-functional evidence was obtained of the essential role of MV in the development of HCM, but the question remains open and needs further study.

Surgical treatment of Type A aortic aneurysm dissection remains one of the most complicated problems in car-diac surgery. The whole surgical treatment experience of such aneurysms by one team is presented in the article. Factors that could have caused the aortic aneurysm (dissection) development are provided. It is shown that experience accumulation, methods improvement of surgical treatment, brain, heart and internal organs protection have allowed to reach the hospital mortality rate of 4.5% over the last 5 years. Data on severe baseline of the operated patients are presented in the paper. It is represented that in the Institute’s experience type A aneurysm dissection accounts for 28.9% of all aneurysms. The vast majority (79.6%) of patients were operated on for acute or subacute type A dissection; 69.2% of patients had type I dissec-tion. All operations were performed under conditions of bypass, moderate hypothermia (30–32 °C) and during the aortic arch replacement (42.4%) – under conditions of deep hypothermia (13–20 °C) and retrograde cerebral perfusion. Surgical correction methods are presented with valve-saving surgeries performed in 63.7% of patients. The surgical treatment results have been shown to be highly dependent on the time of the surgery. Thus, at the initial stage of surgical experience, hospital mortality was 24.1% with a decrease to 16.1% and with a decrease to 4.6% over the last 8 years.
Evaluation of Postoperative Wound Culture Results at an Orthopedic Clinic: A Three-year Analysis

Published: January 2020

Objective: Wound infections constitute the most
prevalent postoperative complication encountered by orthopedists. Lack of
timely and correct treatment may lead to chronic wound infections. Therefore,
this study aims to guide empirical treatment, investigate the isolated bacteria
and associated antibiotic resistance states in wound cultures obtained after
orthopedic surgery.Methods: In the three-year period between January 2016 and end of December 2018,
3100 patients were operated in the Orthopedics and Traumatology Clinic of the
Kirsehir Ahi Evran University Training and Research Hospital. Wound cultures
obtained from patients operated due to wound infections were retrospectively
evaluated. Antibiotic susceptibility tests were performed in accordance with
EUCAST guidelines using disc diffusion methods and the VITEK 2 Compact®
(Biomerieux, France) automated system.Results: A total of 284 wound culture specimens were evaluated, and 85 (22.9%) of
these demonstrated significant bacterial growth. Monomicrobial growth was
detected in 92% and polymicrobial growth was found in 8% of the cultures. The
most commonly isolated microorganism was Escherichia coli (22.3%),
followed by coagulase negative staphylococci (CoNS) (20%), Staphylococcus
aureus (15.3%), Acinetobacter baumannii (9.4%), Pseudomonas
aeruginosa (9.4%) and Streptococcus spp. (5.8%) respectively.
Extended-spectrum beta-lactamase (ESBL) positivity was determined as 100% and
25% for E. coli and K. pneumoniae isolates, respectively.
Carbapenems were found to be the most effective antibiotics to Enterobacteriales
family. Gram positive bacteria were not resistant against vancomycin and
teicoplanin, but 7.6% of S. aureus strains and 57.1% of CoNS were
methicillin-resistant.Conclusion: Identification and monitoring of causative
microorganisms in postoperative wound infections and antibiotic resistance
rates at every hospital is quite important. Taking these findings into
consideration will result in better prevention of infections, increased
treatment success, and decreased antibiotic resistance rates.

Obesity is one of the common metabolic diseases
which is tremendously on the rise. According to the World Health Organization
(WHO), the number of patients has increased three times since 1975. A person
with Body Mass Index (BMI) equal to or higher than 30.0 is considered obese.
Previously considered only as a cosmetic concern, obesity has now been shown to
be an aggravating element for various diseases and disorders including diabetes
and cardiovascular diseases (CVD). The most common drugs subscribed by
physicians include orlistat, rimonabant, liraglutide and sibutramine which have
been proven to be effective to reduce body fat in patients. However, in the
long run, patients have complained about symptoms which are mild like nausea,
insomnia and dizziness to severe complications such as increase in risk of
heart attack or stroke. The following review provides insights about synthetic
drugs, their classification and their side-effects on human health.
Furthermore, a gist of natural products i.e. phytochemicals that can be used as
an alternative to these synthetic drugs has also been discussed in the review.
