Background: Contraceptive use is one of the modern tools use in reducing the scourge of maternal morbidity and mortality from unwanted pregnancy and its attendant complications, challenges of teenage pregnancy and its aftermath, grand multiparity and problems of advanced maternal age and it complications. The uptake of this essential commodity is still not encouraging in sub-Saharan Africa. Objective: The objective of this study was to identify the contraceptive uptake and choice of postpartum contraception among antenatal attendees at Usmanu Danfodiyo University Teaching hospital, Sokoto and the factors associated with contraceptive uptake. Methods: Data was collected using self and interviewer administered questionnaire. Information on socio demographic characteristics, response to contraceptive uptake and choice of postpartum contraception were obtained. This was analyzed using SPSS version 22. Chi-square test was employed to find the association between the study variables and level of significance was set at p <0.05. Results: The mean age of the respondents was 26.93 ± 5.31years, the youngest was 17years and the eldest was 45years. Majority of the respondents were Hausa and the religion was Islam. Most of the respondents had tertiary education but unemployed. About 65% of the respondents planned to take up a method of contraception post delivery. About 42% would prefer implanon followed by jadelle (20.8%). Only 2.3% opted for permanent contraception. There was a significant association between education, occupation and contraceptive uptake. Preference for more children followed by fear of complications were factors responsible against uptake of contraception. Conclusion: Contraceptive uptake was high and a majority of women opted for implants. Educational status and occupation were the factors found to be associated with contraceptive uptake.

Background: Stroke has been a global burden, with increasing morbidity and mortality especially in developing countries. Studies had reported elevated levels of serum homocysteine(hcy) and vitamin B12 (Vit B12) in patients with stroke. Objectives: To determine the relationship between hcy, and Vit B12 outcome in acute ischaemic stroke Materials and Methods: Hundred acute Ischaemic stroke patients were recruited into the study and were followed up for 2years. Serum homocysteine and vitamin B12 was done using ELISA. Patients outcome either dead or alive was recorded at 1 month and at 24 months. Results: Majority of the participants 62% were males with hcy of 1.62±0.37µmol/L and 38% were females with hcy of 1.62±0.31µmol/L. Vit B12 of males were 97.00 (181.30,80.00) pg/ml and females had a Vit B12 of 90.00(140.00,70.00) pg/ml. Thirty-four percent of patients had hyperhomocysteinaemia (>1.7µmol/L) while 64% had normal homocysteine levels. Also, 81% had hypovitaminosis B12 (<199.72pg/ml) and 19% had normal vit B12 on admission. There was no statistically significant difference (p value =0.932) between mean hcy levels of 25 dead patients (1.67 ±0.22µmol/L) and 58 patients that survived at one month (1.68±0.37µmol/L). Similarly, there is no statistically significant difference (p value =0.869) between mean Vit B12 levels of 25 dead patients (113.75±79.37pg/ml) and 58 patients that survived at one month (117.50±87.17pg/ml). After 24months of follow up, 31patients died. There is no statistically significant difference (p value=0.328). between mean homocysteine of 31 dead patients (1.62±0.30µmol/L) and the 47 patients that survived (71±0.36µmol/L). There was no statistically significant difference (p value= 0.214) between the Vitamin B12 concentration of the dead patients (131.29±104.01pg/ml) compared to those who survived (106.81±68.73pg/ml). Conclusion: There is no relationship between Homocysteine and vitamin B12 with outcome in patients admitted with an acute ischaemic stroke

Xanthogranulomatous oophoritis is an uncommon chronic inflammatory process in which native ovarian tissue is destroyed and replaced by marked infiltration by foamy histiocytes, accompanied by other inflammatory cells with or without foci of necrosis or fibrosis. The exact aetiology remains unclear but it has been linked to chronic pelvic inflammatory disease (PID) and Tuberculosis which are endemic in sub-Saharan Africa, including Nigeria. We report a case from a 25 year old female who presented with recurrent lower abdominal pain and an adnexal mass.

Using film as an educational medium in higher education
Authors: Ljujić Bojan , Miljković Jovan
Published: June 2022

This paper is the result of empirical, qualitative research conducted with the aim of studying and gaining an understanding of the benefits of using film as an educational medium in higher education in terms of achieving educational outcomes, providing students with emotional and cognitive stimulation and engagement, and encouraging reflection and self-reflection through a relationship with film as a specific carrier of educational content, which occur in virtual learning environments. The convenience sample consisted of twelve students who attended the course Online Adult Education in 2017-18, and who were intensively engaged in activities that were part of the course's thematic unit Theories of Learning and Online Adult Education. The instructional material used as part of this unit was Akira Kurosawa's film Rashomon (1950). Through two research phases: the discussion phase, which was also the phase of data collection, and the phase of narrative, discourse and content analysis, as well as the grouping of the data obtained through discussion and their thematic analysis, we arrived at results which can also be understood as practical educational implications, and which unequivocally indicate that the use of film as an educational medium encourages: the emotional and cognitive stimulation of students, whether positive or negative; students' perseverance in carrying out assignments and the eventual achievement of learning objectives; introspection, which further defines the quality of learning insights, reflection and self-reflection aimed at attaining concrete learning objectives predefined by learning units.
The possibility of introducing a beginner-level program of extensive reading in Russian language instruction in primary and secondary schools in Serbia
Authors: Medenica Luka
Published: June 2022

The importance of extensive reading for the acquisition of the Russian language has been insufficiently studied in Serbia. The aim of our research was to establish the educational stage when the introduction of a beginner-level program of extensive reading into the teaching of Russian as a second foreign language would be most effective, taking into account the specific character of the acquisition of Russian as another Slavic language. For the purposes of our research we designed a questionnaire aimed at identifying the stage of schooling when the average student is able to read graded readers at A1 level. The research involved 148 respondents - 77 seventh-and eighth-grade primary school students and 71 first-and second-grade students of general and vocational secondary schools. The research was conducted in February and March 2021. A statistical analysis of results was carried out in the JASP program, and data were processed using measures of descriptive statistics and the Pearson product-moment correlation coefficient. The results unequivocally show that a beginner-level program of extensive reading can be introduced both in primary and in secondary schools, as our research proved that students in these age groups can understand graded readers and find them interesting.

Published: June 2022

Research on automatic detecting, tracking and characterizing extreme ice features in the Arctic is based on analyzing and processing satellite synthetic aperture radar (SAR) and optical images. Algorithms to identify ridges from very high-resolution optical data have an accuracy of 86.4% when compared to manual extraction and ridge height has been estimated from shadow. SAR signatures of various ice features have been analyzed and the results indicate that it is possible to identify rubble fields from other ice types.
A Method for Characterizing Uncertainty in Tactical Sea Ice Drift Forecasting
Authors: Blunt Joshua David , Mitchell Douglas , Younan Adel
Published: June 2022

Hydrocarbon exploration in the high-Arctic offshore region may require enhanced station keeping capability in ice due to a limited open water summer season and/or the potential for temporary pack ice intrusions during a nominal open water season. Ice management systems have been employed as a means to improve station keeping ability in the presence of drifting sea ice, but accurate ice drift forecasting is central to improving the reliability of any ice management system. A rigorous approach to both (1) quantifying and (2) communicating the uncertainty associated with sea ice drift forecasting is proposed in this paper.
Fracture Analysis of a Steel Plate Loaded by Ice
Authors: Seif Tayyebe , Jamaly Abdullah , Daley Claude
Published: June 2022

There are several theories used to describe the fracture process including Linear Elastic Fracture Mechanics (LEFM), Elastic-Plastic Fracture Mechanics (EPFM), and Cohesive Zone Models (CZM), which allow for development of predictive capabilities. The main disadvantage of LEFM and EPFM techniques is that only structures with an initial crack can be modeled. Other drawbacks of these techniques are geometry dependence and validity limits. In contrast, CZM can simulate fractures in any structures, with or without a crack. CZM is not confined to a class of materials, but can be used for arbitrary materials. In this paper, the CZM is used to numerically simulate crack initiation and growth in a steel plate. Within the CZM, material separation (i.e. damage of the structure) is described by interface elements, which open irreversibly and lose their stiffness at failure, causing the continuum elements to be disconnected.
Simulation of Managed Sea Ice Loads on a Floating Offshore Platform using GPU-Event Mechanics
Authors: Daley Claude , Alawneh Shadi , Peters Dennis , Blades Gary , Colbourne Bruce
Published: June 2022

The paper describes a GPU-based event mechanics (GEM) model of the action of managed pack ice on a floating offshore structure. The ice cover is represented by a large number of discrete polygonal ice floes, of varying thickness. Each ice-structure contact is modeled, as is every ice-ice contact. Time histories of total platform force (net mooring force) and platform position are presented. Ice coverage, floe sizes and thickness are varied in the simulation set. The work represents a further exploration of the possibilities of GEM technology, which was previously used to explore both resistance and local structural loads for ships transiting pack ice. The work is part of a research project at Memorial University of Newfoundland called STePS2 (Sustainable Technology for Polar Ships and Structures).
Numerical Modelling of the Stationkeeping of Drillships in Ice
Authors: Sayed Mohamed , Kubat Ivana , Wright Brian , Millan James
Published: June 2022

Numerical simulations are carried out to examine the interaction of a managed ice cover with a drillship. Station keeping is maintained using a mooring system and Thruster-Assisted Mooring. The ice model is based on solving the momentum and constitutive equations, which determine the stresses and deformations of the ice cover. The drillship is modeled as rigid body of three degrees-of-freedom: surge, sway and yaw. A Base Case examines a managed ice cover consisting of floes with sizes ranging from 20 m to 50 m, and a uniform ice thickness of 1 m. The ice cover moves at 0.3 m/s along the surge direction. The drillship has a length of 130 m, beam of 42 m and a mass of 100,000 Mt. The resulting ice force shows peak values reaching 1.7 MN. Analysis of the ice force-time records gives probability distributions of the peak forces, the time required for the force to reach the peak (rise time to peak force), and the rate of force increase. The work includes a parametric study, which examines the effects of the size of the drillship, ice thickness variations, the existence of large ridge fragments in the ice cover, the presence of brash ice, patterns of icebreaking tracks, and thruster assistance to the mooring system.
A Semi-Empirical Method of Ice Resistance Prediction in Level Ice
Authors: Jeong Seong-Yeob , Choi Kyungsik , Kang Kuk-Jin , Cho Seong-Rak , Lee Chun-Ju
Published: June 2022

We introduce a semi-empirical model that can determine a ship’s performance in level ice based on Lindqvist’s model and develop a simple model for calculating ice resistance. This model assumes that contact between the ship and the ice is a case of symmetrical collision, and two contact cases are considered. Crushing and submersion forces are calculated via Lindqvist’s formulas, and the breaking force is determined by a concept of energy consideration during ship and ice impact. The average difference between the predicted data and the model test data is about 4.6%, but the total resistance showed fairly close agreement with both. In addition, the friction coefficient may have considerable influence on breaking and submersion forces.
Challenges Implementing ISO 19906 for Probabilistic Assessment of Multi-year Sea Ice Loads on Sloping Structures
Authors: Fuglem Mark , Richard Martin , Thijssen Jan
Published: June 2022

The ISO standard ISO 19906:2010 provides guidance for determining design loads for offshore structures in arctic and sub-arctic regions, using both deterministic and probabilistic approaches. References are provided for models of both first and multi-year ice loads on both vertically-faced and sloping structures.

ISO 19906 indicates that consideration should be given to limit stresses at the ice structure interface based on the dominating ice failure mechanisms, limit forces associated with the available driving force that can act on the interacting ice floe due to wind, currents and surrounding ice, and the kinetic energy of the impacting feature. Analyses show that the kinetic energy of an impacting multi-year floe driven by surrounding ice will result in larger loads than those from driving forces alone. In order to determine penetrations and maximum loads, it is then necessary to consider the variation in load with penetration during an impact.

In the case of multi-year ice loads on sloping structures, full-scale data to properly validate models is lacking. Several models are available that estimate maximum loads for level ice interactions with sloping structures. These models can partially account for rubble forming on the structure during the interaction thereby increasing loads, though the ability to estimate rubble heights for different structure shapes and ice conditions at present is limited. In the case of multi-year ridges, several models are available that estimate the maximum load during the interaction of a prismatic beam shaped ridge contacting a conical structure. Data and model for loads from more realistic multi-year ridge shapes are lacking. Additionally, the influence of rubble existing on the structure at the time the ridge impacts is not explicitly considered.

This paper examines issues in determining probabilistic design loads for multi-year interactions with sloping structures and presents sensitivity results for key assumptions and parameters. The analyses were carried out using the Sea Ice Loads Software (SILS) developed by C-CORE as part of a Joint Industry Project (JIP) to implement ice load models referenced in ISO 19906 within a probabilistic framework for the purpose of determining design loads. Interpretation was required where ISO 19906 does not provide explicit details on the models and probabilistic implementation. Monte-Carlo simulation was selected for carrying out probabilistic calculations of design loads as this approach is robust.
Analysis of Experimental Data and Quantifying Influence of Dimensionless Material Properties, Velocity and Aspect Ratio on Ice-induced Forces on Vertical Structures
Authors: Arunachalam Aaruun V.M.
Published: June 2022

In this paper, the quantitative influence of aspect ratio (B/h), and dimensionless velocity or thickness Froude number [TFN = u/√(gh)] on dimensionless ice-induced pressures (pe/ρiu2) is briefly reviewed and discussed. Since material properties of ice (E, σf, K1c) have not been reported for many data-sets, a strategy for generating appropriate material properties for ice is proposed. Two dimensionless terms for material properties of ice, {(E/σf)×[K1c/(σf√h)]} and {[K1c/(σfu)]×√[E/(ρih)]} were identified and their influence on pe/ρiu2 is discussed. It was found that (1) pe/ρiu2 on rigid vertical structures decreases with (a) increasing B/h at a rate of about 0.42, when u/√(gh) and {[K1c/(σfu)]×√[E/(ρih)]} remain constant; (b) pe/ρiu2 decreases with increasing u/√(gh) at a rate of about 1.80 when u/√(gh) is < about 6.0×10-3and at a rate of about 1.93 when u/√(gh) is > about 6.0×10-3 when B/h and {[K1c/(σfu)]×√[E/(ρih)]} remain constant. (2) Preliminary analyses of the datasets shows that pe/ρiu2 decreases with increasing {(E/σf)× [K1c/(σf√h)]} at a rate of 0.335 and 0.469 and that pe/ρiu2 decreases with increasing {[K1c/(σfu)]×√[E/(ρih)]} at a rate of 0.729 and 0.808. (3) It was also found that shapes of structures do not influence dimensionless ice-induced pressures on structures.
Uncertainty in 100 and 10,000 Year Ice Loads on Offshore Structures
Authors: McKenna Richard , Fuglem Mark , Crocker Greg
Published: June 2022

The ISO 19906 arctic structures standard specifies that ice loads be calculated at the extreme level (100 year return period) for verifying ultimate limit states and at the abnormal level (10,000 years) for accidental/abnormal limit states. Since ice load measurements on structures have only been made over much shorter time periods, concerns are often expressed about the accuracy to which 10,000 year values can be estimated.

In this paper, the uncertainties in 100 and 10,000 year loads are considered through examples based on experience with calculations of loads on structures in different iceberg and sea ice environments. For icebergs, it is necessary to consider the size distribution of icebergs (including the potential presence of extremely large icebergs and ice islands) as well as drift velocities and shapes that can govern high return- period loads for fixed structures. With sea ice, abnormal-level loads can be governed either by the presence and geometrical properties of large discrete features (e.g. first-year ridges and stamukhi, or in the arctic, multi-year floes with thick ridges), or by very thick ice as a result of thermal growth. It is demonstrated how errors in key contributing ice parameters can influence extreme-level loads, and the relationship between level/rafted ice loads at the abnormal level and the factored (1.35) extreme-level values, and how these uncertainties might be considered in the design process.
A Mathematical Model of Icebreaking for Safe Speed Assessment
Authors: Sazidy Mahmud , Daley Claude , Colbourne Bruce
Published: June 2022

This paper presents numerical and mathematical models of ship-ice breaking. Two ship-ice breaking scenarios are considered, ice wedge breaking and level ice breaking. Numerical models of both breaking scenarios account for ice crushing, ice flexure and water foundation effect. For ice wedges, the effect of ship speed on the ice breaking process is investigated for different ship angles, ice wedge angles and ice thicknesses. The level ice breaking is investigated with and without radial cracks. The mathematical model is developed based on validated numerical results. Both models can be useful for safe speed evaluation, ice management and ship design.
Behavior of Ice Covers Under Moving Loads – the Driving Mechanism
Authors: Lanteigne Michel , Van Der Vinne Gary
Published: June 2022

Measurements of the response of a floating ice cover to a loaded vehicle travelling at various speeds indicate that the “deflection bowl” created under the weight of the vehicle behaves like a vessel which is carrying the vehicle over the water surface. Because the ice cover is flexible, the bowl changes shape as the forces acting on it change with speed. Results show that: 1) as vehicle speed increases towards “critical speed” the depth of the bowl increases from the effect of the Bernoulli principle; 2) the depth of the bowl diminishes above critical speed from dynamic lift; 3) critical speed is sensitive to water depth – which is predicted by the Bernoulli principle.
The Personal Papers of American Sailors, 1890s–1940s
Authors: Tummino Annie
Published: June 2022

Personal papers in the archives at Maritime College, State University of New York, document the lives of alumni from the school’s founding in 1874 through the early decades of the 20th century. Journals, diaries, memoirs, and reminiscences located in these collections provide evidence of what it was like to work on a ship, far from home, travelling to foreign lands. In this article, I explore first-hand accounts of maritime life by Van Horne Morris, my maternal grandfather and a 1938 graduate of the Massachusetts Nautical School (now known as Massachusetts Maritime Academy), and several alumni of the New York Nautical School (now known as SUNY Maritime College), who graduated between 1896 and 1929. Close reading of their letters and manuscripts reveals echoes of a maritime literary tradition rooted in the antebellum-era United States. Comparing and contrasting the style and content of their writing to antecedents in the 19th century also illuminates continuity and changes in maritime labour and culture over time.
Colonialism, Computerized
Authors: Castron Melissa M.
Published: June 2022

This article argues for the incorporation of a transdisciplinary approach to cartographic materials in archives, especially in relation to archival description and preservation. Delving into the theoretical foundations and developments in the fields of archival studies and cartography, it explores the creation of cartographic materials and focuses on their processing by archives (i.e., their appraisal, arrangement, description, and preservation and the means of making them available to archival researchers). The lag between theoretical developments and practical applications is illustrated through the creation and management of the Canada Land Inventory (CLI) and Canada Geographic Information System (CGIS) materials held by Library and Archives Canada. An analysis of the creation and ongoing management of these materials highlights the role of cartography and archives in the formation of Canada as a modern colonial state and in the ongoing dispossession of Indigenous Peoples.

In order to analyze the causes of star sensor performance degradation and attitude measurement accuracy reduction in space radiation environment, the total ionizing dose effects on complementary metal oxide semiconductor (CMOS) star sensor performance are studied. By using an established outfield star sensor test system, the Orion Nebula and the zenith direction of the sky are imaged. Through the experimental processes of star map data acquisition, star point extraction and star map matching, the influence mechanisms of complementary metal oxide semiconductor active pixel sensor (CMOS APS) noises on background gray mean value of star map and number of identified stars are analyzed. A recognition algorithm for finding stars annihilated by radiated noise is proposed. Through theoretical derivation, the quantitative relationships between CMOS APS dark current noise, dark signal non-uniformity noise and photon response non-uniformity noise and star centroid positioning error are established. The γ radiation results show that the image gray-mean of the whole star map increases, the number of identified stars decreases, and the star point centroid positioning accuracy decreases, which seriously affect star map recognition of star sensor. This research provides a theoretical basis for the radiation-resistant reinforcement design of high precision star sensors.
Towards a unified model of naive T cell dynamics across the lifespan
Authors: Rane Sanket , Hogan Thea , Lee Edward , Seddon Benedict , Yates Andrew J
Published: June 2022

Naive CD4 and CD8 T cells are cornerstones of adaptive immunity, but the dynamics of their establishment early in life and how their kinetics change as they mature following release from the thymus are poorly understood. Further, due to the diverse signals implicated in naive T cell survival, it has been a long-held and conceptually attractive view that they are sustained by active homeostatic control as thymic activity wanes. Here we use multiple modelling and experimental approaches to identify a unified model of naive CD4 and CD8 T cell population dynamics in mice, across their lifespan. We infer that both subsets divide rarely, and progressively increase their survival capacity with cell age. Strikingly, this simple model is able to describe naive CD4 T cell dynamics throughout life. In contrast, we find that newly generated naive CD8 T cells are lost more rapidly during the first 3–4 weeks of life, likely due to increased recruitment into memory. We find no evidence for elevated division rates in neonates, or for feedback regulation of naive T cell numbers at any age. We show how confronting mathematical models with diverse datasets can reveal a quantitative and remarkably simple picture of naive T cell dynamics in mice from birth into old age.

Prokinetic Agents
Authors: Song Hyo Yeop , Jung Sung Won , Kim Yong Sung
Published: June 2022

Gastrointestinal (GI) prokinetic agents are drugs that increase GI motility and promote the movement of contents in the GI tract by amplifying and controlling the contraction of GI smooth muscle. Currently used prokinetics increase GI motility by acting as a dopamine D2 receptor antagonist (e.g., metoclopramide, domperidone, levosulpiride) and 5-HT4 receptor agonist (e.g., mosapride, prucalopride). Some prokinetics also have a cholinesterase inhibitory property (e.g., itopride), and herb-derived prokinetics (e.g., motilitone) affect multiple receptors. Depending on the type and distribution of receptors on which the prokinetics bind, the effect(s) may be regional or throughout the GI tract. Most prokinetics have been used for functional dyspepsia and gastroparesis because they mainly affect upper GI motility. However, prucalopride, a highly selective 5-HT4 receptor agonist, is used primarily to treat chronic constipation and pseudo-obstruction. Dopamine D2 receptor antagonists also inhibit the D2 receptor in the medulla oblongata chemoreceptor trigger zone; therefore, they can treat nausea and vomiting. However, short term use of dopamine D2 antagonists at an appropriate dose is recommended because of their potential for central nervous system side effects by penetrating the blood-brain barrier. It is necessary to know the mechanism of action, each clinical trial’s characteristics, and the side effects of prokinetics to obtain the best clinical outcomes. This article aims to summarize the results of clinical studies related to the impact of currently available prokinetic agents in Korea on GI motility.
Role of active joint position sense on the upper extremity functional performance tests in college volleyball players

Published: June 2022

Background

It has been well established that proprioception plays a decisive role in shoulder stability and sport performance. Notwithstanding, there is a lack of clear association between active joint position sense (AJPS) and the performance of upper-extremity functional performance tests. The aim of this study was to determine whether the AJPS of the shoulder complex is associated with the performance of college volleyball players with the following functional tests: Y-Balance Test-Upper Quarter (YBT-UQ), Closed Kinetic Chain Upper-Extremity Stability Test (CKCUEST), and Seated Medicine Ball Throw (SMBT). The secondary aim was to investigate whether the magnitude of the proprioception error through the AJPS had the ability to act as a predictor for functional test scores.

Methods

Cross-sectional study with a convenience sampling. Healthy college volleyball players (≥12 h of training/week), 30 males and 22 females, between 18 and 26 years of age were included. AJPS of the shoulder (90° of flexion (90°Flex), 90° of internal rotation at 90° of abduction (90°IR/ABD), 90° of external rotation at 90° of abduction (90°ER/ABD)) and three upper-extremity functional performance tests (YBT-UQ, CKCUEST and SMBT) were assessed. A Pearson’s test and a stepwise multiple linear regression analysis were used to determine possible associations and relationships between outcome measures, respectively.

Results

The analysis revealed that AJPS at 90°IR/ABD and 90°ER/ABD were the only proprioceptive variables with an association to the YBT-UQ and SMBT. Despite these relationships, only the AJPS at 90°IR/ABD was associated with the performance of the YBT-UQ in; superolateral direction (β = −0.7; 95% CI [−1.3 to 0.1]; p = 0.025); inferolateral direction (β = −1.5; 95% CI [−2.1 to −0.8]; p = 0.001); and composite score (β = −0.8; 95% CI [−1.3 to −0.3]; p = 0.002). From these, AJPS at 90°IR/ABD mainly explained the variability of YBT-UQ (inferolateral direction) performance (R2 = 0.32; %R2 = 0.32). Our findings allow for a possible expanded role for proprioception as a contributing factor in upper limb motor control during functional movements. Further research is required to explore and distinguish the associations between proprioception, motor control and sport performance involving the upper limbs.

Authors: Perumal P Ganesh , Patil Asha B , Jnaneshwara KB
Published: June 2022

Introduction: The incidence of orthopaedic implantation and implantation associated infections were correspondingly increasing among the elderly and trauma patients. The resistance among the pathogens pose a unique challenge to the clinicians in the management of the infection. Extended-Spectrum Beta-Lactamase (ESBL), AmpC beta-lactamases (AmpC), Metallo Beta-Lactamases (MBL) and Methicillin-Resistant Staphylococcus aureus (MRSA) producing bacterial pathogens are responsible for a high rate of relapsing infections and outbreaks of nosocomial infections. Aim: To focus on accounting the incidence of ESBL, AmpC, MBL and MRSA and its antibiogram for effective management of implant associated infection. Materials and Methods: The present study was a prospective observational study which was conducted using various samples like pus, wound swab, serous discharge. These samples were collected under aseptic precautions in sterile containers for the period of one year (February 2015-February 2016). A total of 200 samples were inoculated on Blood agar and McConkey agar and identified. The isolates were tested for detection of ESBL, AmpC, MBL and MRSA as per standard protocol. The statistical analysis was performed using Statistical Package for the Social Sciences (SPSS) software version 20.0 Chicago, USA. Results: Most commonly used implants were intramedullary interlocking nail 138 (65.7%) followed by dynamic compression plates 23 (11.0%) and anatomical plates 18 (8.6%). Of the total of 200 samples, 190 (95%) samples yielded monomicrobial isolates and 10 (5%) samples yielded polymicrobial isolate. gram negative isolates 108 (51.4%) were marginally higher than gram positive isolates 102 (48.6%). The predominant isolate was S. aureus 81 (38.5%) followed by Klebsiella spp. 28 (13.3%) and Pseudomonas aeruginosa 21 (10.0%). In gram negative isolates, 76 (70.4%) were ESBL and/or AmpC producers. Of which, 48 (44.4%) were ESBL and AmpC co-producers. There were no MBL producing isolates. In gram positive isolates, majority were S. aureus 81 (79.4%) followed by Coagulase-negative Staphylococcus 21 (20.6%). Out of 81 S. aureus isolates, 46 (56.8%) were MRSA. Out of 21 CoNS, majority 17 (81%) isolates were methicillin-resistant. Implant failures were observed in 28 (14%) cases. Out of 28, majority 12 (42.8%) of the implant failures were MRSA. Conclusion: High rates of ESBL, AmpC and MRSA infections associated with implant surgeries indicate the necessity to formulate antibiotic policies and control measures. ESBL and AmpC producing strains were found to show higher rates of resistance to the various class of antibiotics when compared to non-ESBL and non-AmpC producers. MRSA isolates were found to show higher rates of resistance to various classes of antibiotics when compared to MSSA
