Impact of an Antimicrobial Stewardship Program on Antimicrobial Utilization, Bacterial Susceptibilities, and Financial Expenditures at an Academic Medical Center
Authors: Timbrook Tristan T. , Hurst John M. , Bosso John A. 
Published: October 2016

Background Antimicrobial stewardship programs (ASPs) have the potential to improve patient outcomes, decrease microbial resistance, increase patient safety, and decrease costs. However, to justify the costs involved with providing an ASP, it is necessary to assess its impact in achieving these outcomes on an ongoing basis. Objective The purpose of this study was to characterize the overall impact of the ASP at an academic medical center. Methods Quasi-experimental, before and after stewardship program implementation, retrospective analyses of quarterly antimicrobial utilization, bacterial susceptibilities, and antibiotic acquisition costs were utilized. Results Mean stewardship-focused antibiotic utilization was 510.3 defined daily doses (DDD) per 1,000 patient days for the pre-ASP period and 426.4 DDD per 1,000 patient days for the ASP period (16.4% decrease; p < .001). Significant changes in Pseudomonas aeruginosa susceptibility to tobramycin (8% increase; p = .006) and piperacillin-tazobactam (8% decrease; p = .024) were noted. Changes in susceptibility of Staphylococcus aureus to methicillin (7% increase, p = .012) were also observed. ASP-focused antibiotic expenditures decreased from $4,028,068 in fiscal year (FY) 2010 to $2,135,173 in FY2013 ( p = .01). Conclusions ASP initiatives were associated with an observed reduction in stewardship-focused antibiotic utilization. Significant changes in susceptibilities of some bacteria were noted but did not seem to consistently reflect antibiotic utilization changes. Significant decreases in antimicrobial expenditures were observed. Observed outcomes are temporally related to shifts in antimicrobial selection through the initiation of stewardship program–driven antibiotic policy changes. These outcomes have been used to justify and expand our stewardship program moving forward.

Published: October 2016

Objective To evaluate the impact of a multifaceted, pharmacy-driven, unit-based transitions of care (TOC) program on all-cause 30-day readmission rates and to assess readmission rates in predefined subgroup patient populations. Methods This prospective study included adult patients who were discharged from the pilot unit from January 5 to January 30, 2015. Patients who expired during hospitalization, left the hospital against medical advice, or transferred to another unit or nonaffiliated hospital were excluded. Possible pharmacist interventions included daily medication profile review, delivery of discharge medications to the bedside, counseling, and communication of a discharge medication list to follow-up providers. Patients had a 30-day follow-up period from the date of discharge to assess for readmission. Results A total of 131 patients were screened and 94 patients were included. The primary outcome evaluating 30-day readmission rates occurred in 12.8% of patients in the pilot group versus 18.8% of patients in the historical control group ( p = .26). None of the patients who received all possible pharmacist interventions were readmitted. Secondary outcomes assessing readmission rates in predefined subgroup populations as well as length of stay were comparable between the 2 groups. All identified medication discrepancies were resolved prior to discharge. Conclusion Readmission rates during the pilot were numerically lower but not statistically significant when compared with historical data. Enhancement of the pharmacy-driven TOC services through allocation of additional resources is in progress. Further investigation is warranted to determine the impact of a TOC pharmacist after the service is sustained.
Make faces, Zulu! Make faces, Zulu! Silent comedy and ethnic stereotyping in early South African movies, 1916–1921
Authors: Parsons Neil 
Published: October 2016

Abstract
The comedies of African Film Productions were filmed by American and British directors, with casts drawn mainly from stage actors on overseas tours. After an experiment combining actors with cartoon animation in 1916, three farces of British-American type were directed by B.F. Clinton, notably with A.F.P.’s Zulu star Goba’s head stuck inside a valuable vase. Five short comedies were directed by Dick Cruikshanks in 1917, three with large predominantly African casts. The Zulutown series, in the mould of Charlie Chaplin slapstick, was widely shown to African audiences in subsequent years. A Christmas pantomime, which critiqued the use of child labour on farms, featured a small black child at its centre. And Then–? was a parody of blood-and-thunder melodrama. The independent production Thoroughbreds All (1918) was a satire on the morality of horse-racing. These comedies are remarkable for being plot-centred rather than constructed around the antics of well-known comedians, as were most comedy films made overseas.
Diamonds at the meeting of her thighs: Representations of gender and sexuality in U-Carmen eKhayelitsha
Authors: Stobie Cheryl 
Published: October 2016

Abstract
The heroine of Prosper Mérimée’s 1845 novella, Carmen, appears as an archetypal femme fatale who lures unsuspecting men to their destruction by means of her manipulative sexuality. While Georges Bizet’s 1875 opera, Carmen, reveals the psychology of masculine anxieties, sexual jealousy and murderous rage, his character, Carmen, expresses her credo of autonomous sexuality, and can be seen as a prototypical modern woman. My article examines the representations of the female protagonist’s sexuality in a contemporary South African film that re-works the Carmen story in an African context. I argue that U-Carmen eKhayelitsha/Carmen in Khayelitsha, directed by Mark Dornford-May (2005), does not realize the potential significance of Carmen’s sexuality. I trace the ways in which dance is not used to good effect in the film. In addition, I show that the film highlights traditional masculinity in various ways, such as offering disturbing parallels between the ritual slaughter of a bull and the murder of Carmen. I conclude that U-Carmen eKhayelitsha displays revisionist and ambivalent gender politics.
What languages do aliens speak? Multilingual ‘Otherness’ of diasporic dystopia in District 9
Authors: Mizoguchi Akiko 
Published: October 2016

Abstract
District 9 (Blomkamp, 2009), a South African science-fiction film, is noted for its dystopian vision. It is mostly set in a dilapidated township of Johannesburg called ‘District 9’, where ‘abject’ refugee aliens and Nigerian gangs reside. Moreover, the district in the end becomes a chaotic battlefield where the South African mercenaries hired by neo-liberal Multi-National United and the Nigerians mercilessly hunt Wikus van de Merwe, an MNU employee, whose mutating body holds a key to operating alien weaponry. These temporary dwellers of District 9 are informed by many levels of displacement and marginalization and are presented as the ‘Other’ to the residents of the ‘human’ world and this ‘Other’ worldliness is intensified by the way in which the director forges the ‘South African’ multilingual condition in the film. This article discusses the colonial and segregationist world-view on the post-apartheid South Africa in the representation of the ‘Other’ multilingual and diasporic landscape.
Low‐frequency stimulation of group III and IV hind limb afferents evokes reflex pressor responses in decerebrate rats
Authors: Harms Jonathan E. , Copp Steven W. , Kaufman Marc P. 
Published: October 2016

AbstractContraction of freely perfused hind limb muscles in decerebrate rats evokes the exercise pressor reflex, resulting in sympathetic activation and increased blood pressure. This reflex is propagated along mechanically sensitive group III and metabolically sensitive group IV afferent nerve fibers. Recent research by our laboratory has focused on the exaggeration of the exercise pressor reflex in decerebrate rats with simulated peripheral artery disease, which was induced by ligating the femoral artery for 72 h before the start of the experiment. Recently, we showed that ligating the femoral artery increased the responses of single fiber group III and IV triceps surae muscle afferents to static contraction. The objective of this study was to determine if electrical stimulation of group III and IV afferents at frequencies approximating those occurring during static contraction was capable of reflexively increasing arterial blood pressure. We directly stimulated muscle afferents in the absence of muscle contraction for both freely perfused and ligated rats. We established 0.25 Hz as the minimal stimulation frequency to observe a sustained blood pressure response. The blood pressure response increased in a graded fashion as both stimulus frequency and motor threshold were increased. Additionally, we observed similar blood pressure responses from both freely perfused and ligated rats, suggesting that spinal and medullary processing of group III and IV afferent input plays no role in augmenting the pressor response to contraction caused by femoral artery ligation.
Hydrothermal metasomatism of a peralkaline granite pegmatite, Khaldzan Buragtag massif, Mongolian Altai; complex evolution of REE-Nb minerals

Published: October 2016

Abstract
The low-temperature hydrothermal alteration of certain rare-metal minerals is recorded in a quartz-epidote metasomatite from the Tsakhirin Khuduk occurrence in the Khaldzan-Buragtag Nb-REE-Zr deposit, Mongolian Altai. A peralkaline granitic pegmatite was metasomatized by hydrothermal fluids released from associated intrusions, with the formation of, inter alia, chevkinite-(Ce), fergusonite-(Nd) and minerals of the epidote group. The textural pattern indicates recrystallization and coarsening of these phases. Later, low-temperature alteration by fluids resulted in the chevkinite-(Ce) being replaced by complex titanite-TiO2 -cerite-(Ce)-hingganite-hydroxylbastnasite-( Ce) assemblages. Calcite formed late-stage veins and patches. The hydrous fluids were poor in F and CO2 but had high Ca contents.
Floodplain morphodynamics and distribution of trace elements in overbank deposits, Vistula River Valley Gorge near Solec nad Wisłą, Poland
Authors: Falkowska Ewa , Falkowski Tomasz , Tatur Andrzej , Kałmykow-Piwińska Agnieszka 
Published: October 2016

AbstractGeological and geochemical investigations were carried out in the floodplain of the Vistula River Valley gorge near Solec nad Wisłą (Małopolska Gorge of the Vistula River). Geological mapping was supported by DEM and remote sensing analysis. Sediment samples were taken from depths of 0.5 m and 1.5 m from all geomorphological features identified. The geochemical analysis included determination of Cr, V, Sr, Ba, Ni, Cu, Co, As, Pb and Zn concentrations. Results indicate that the main factors affecting the pattern of features in the floodplain of this area are (1) the highly dynamic flood flow in the narrow section of the gorge and (2) the relief of the top surface of the sub-alluvial basement. The variable concentrations of trace elements are closely related to the floodplain features. Their concentrations can be considered as valuable geochemical proxies that enable a more thorough reconstruction of the sedimentary evolution of the Vistula River Valley and other similar river valleys, especially in gorge sections.

Published: October 2016

Abstract
This work presents studies of the structure and functional properties of coatings deposited onto indexable inserts made of nitride and sialon tool ceramics with the required properties, i.e. high adhesion, microhardness, high resistance to abrasive and diffusion wear in working conditions of high-performance cuttings tools. In the present paper the results of the investigations of the structure, texture, mechanical and functional properties of the Ti(C,N), (Ti,Al)N, Ti(C,N)+(Ti,Al)N coatings were presented. The 80% increase in the hardness of the coatings in comparison to the substrate material was reported. Test coatings are characterized by good adhesion to the substrate. The maximum Lc load of (Ti,Al)N coat applied to the substrate from the nitride ceramics is equal to 42 N. In the studied coatings compressive stresses were found. The results of mechanical properties investigations, especially tribological ones correlate with the results of exploitation tests carried out during the cutting test.

Published: October 2016

Abstract
This paper attempts to summarise the microstructural changes which take place in aluminium bronzes during heat treatment. Another objective of this study was to map the potential of a certain type of aluminium bronzes for undergoing martensitic transformation. The methods, which were chosen for assessing the results of heat treatment with regard to their availability, included measurement of hardness and observation of microstructure using light and scanning electron microscopy, Additional tools for evaluation of microstructure comprised measurement of microhardness and chemical analysis by EDS. An important part of the experiment is observation of microstructural changes in the Jominy bar during the end-quench test. Upon completing experiments of this kind, one can define the heat treatment conditions necessary for obtaining optimum properties. In addition, the paper presents important findings on how to improve the corrosion resistance of aluminium bronzes by special heat treatment sequences.

Published: October 2016

Abstract
One of the innovative technology of producing the components is Selective Laser Melting (SLM) belongs to additive manufacturing techniques. SLM technology has already been successfully applied in the automotive, aerospace and medical industries. Despite progress in material flexibility and mechanical performances, relatively poor surface finish still presents a significant weakness in the SLM process.
The scope of the present article is the study the influence of selective laser melting parameters such as laser power, scanning speed, exposure time and hatch spacing through additive manufacturing as well as the orientation of the model corresponding to the laser beam on the surface characteristic of the components made from Ti-6Al-4V alloy. By using optimized process parameters, a low surface roughness can be obtained.
In research, the machine for the selective laser melting of metal powders Renishaw AM 125 device was used. Based on experiment plan, 32 models were produced, which were examined to define the surface roughness and thus represent an influence of process parameters and the orientation on the model surface quality.
The article discusses the fundamental factors determining the roughness that gives invaluable knowledge to improve the surface quality of SLM parts.

Published: October 2016

AbstractThis paper presents the evaluation of the service life of dissimilar repair welded joint from Cr-Mo/Cr-Mo-V steel after 200,000 h service under creep condition. The investigations of microstructure using scanning electron microscopy, investigations of mechanical properties at room and elevated temperature as well as creep tests of the basic material from Cr-Mo and Cr-Mo-V steel and welded joint from these steels were carried out. The investigations allowed the time of further safe operation of the repair welded joint in relation to the residual life of the materials to be determined. The evaluation of residual life and disposable residual life, and thus the estimation or determination of possible time of further safe operation, is crucial when the elements are operated much beyond the design work time.

Published: October 2016

Abstract
In this work, the influence of a high power diode laser surface treatment on the structure and properties of aluminium alloy has been determined. The aim of this study was to improve the mechanical and tribological properties of the surface layer of the aluminium alloy by simultaneously melting and feeding tungsten carbide particles into the molten pool. During the process was used high-power diode laser HPDL. In order to remelt the aluminium alloy surface the HPDL laser of 1.8, 2.0 and 2.2 kW laser beam power has been used. The linear laser scan rate of the beam was set 0.5 cm/s. In order to protect the liquid metal during laser treatment was used argon. As a base material was used aluminium alloy ENAC-AlMg9. To improve the surface mechanical and wear properties of the applied aluminium alloy was used biphasic tungsten carbide WC/W2C. The size of alloying powder was in the range 110-210 µm. The ceramic powder was introduced in the remelting zone by a gravity feeder at a constant rate of 8 g/m.

Published: October 2016

Abstract
The paper presents the results of the properties of flame sprayed ceramic coatings using oxide ceramic materials coating of a powdered aluminium oxide (Al2O3) matrix with 3% titanium oxide (TiO2) applied to unalloyed S235JR grade structural steel. A primer consisting of a metallic Ni-Al-Mo based powder has been applied to plates with dimensions of 5×200×300 mm and front surfaces of Ø40×50 mm cylinders. Flame spraying of primer coating was made using a RotoTec 80 torch, and an external coating was made with a CastoDyn DS 8000 torch. Evaluation of the coating properties was conducted using metallographic testing, phase composition research, measurement of microhardness, substrate coating adhesion (acc. to EN 582:1996 standard), erosion wear resistance (acc. to ASTM G76-95 standard), and abrasive wear resistance (acc. to ASTM G65 standard) and thermal impact. The testing performed has demonstrated that flame spraying with 97% Al2O3 powder containing 3% TiO2 performed in a range of parameters allows for obtaining high-quality ceramic coatings with thickness up to ca. 500 µm on a steel base. Spray coating possesses a structure consisting mainly of aluminium oxide and a small amount of NiAl10O16 and NiAl32O49 phases. The bonding primer coat sprayed with the Ni-Al-Mo powder to the steel substrate and external coating sprayed with the 97% Al2O3 powder with 3% TiO2 addition demonstrates mechanical bonding characteristics. The coating is characterized by a high adhesion to the base amounting to 6.5 MPa. Average hardness of the external coating is ca. 780 HV. The obtained coatings are characterized by high erosion and abrasive wear resistance and the resistance to effects of cyclic thermal shock.
