Aims

The aim of this study was to present the long-term surgical outcomes, complications, implant survival, and causes of implant failure in patients treated with the modified Harrington procedure using antegrade large diameter pins.

Patients and Methods

A cohort of 50 consecutive patients who underwent the modified Harrington procedure for periacetabular metastasis or haematological malignancy between January 1996 and April 2018 were studied. The median follow-up time for all survivors was 3.2 years (interquartile range 0.9 to 7.6 years).

Results

The five-year overall survival rate was 33% for all the patients. However, implant survival rates were 100% and 46% at five and ten years, respectively. Eight patients survived beyond five years. There was no immediate perioperative mortality or complications. A total of 15 late complications occurred in 11 patients (22%). Five patients (10%) required further surgery to treat complications. The most frequent complication was pin breakage without evidence of acetabular loosening (6%). Two patients (4%) underwent revision for aseptic loosening at 6.5 and 8.9 years after surgery. Ambulatory status and pain level were improved in 83% and 89%, respectively.

Conclusion

The modified Harrington procedure for acetabular destruction has low complication rates, good functional outcome, and improved pain relief in selected patients Cite this article: Bone Joint J 2019;101-B:1557–1562

Published: November 2019

Phenolic compounds are widely distributed in almost all higher plants and are present in different tissues. The quality and quantity of phenolics are used as criteria for variety identification. The present study has been planned to determine the phenolic composition of Pistacia vera. Total phenolic content and concentration of flavonoids of eight different extracts, from the floral buds and leaves of Pistacia vera. (Anacardiaceae) were determined using spectrophotometric methods. The total phenolic content ranged from 401.64 to 513.77 (mg GAE/g DW). The total flavonoid concentrations varied from 8.28 to 67.94 mg CE/g. Antioxidant activity was assessed by three methods: DPPH°+, β-carotene and ABTS and determined respectively as IC50 (mg/mL), CAA and PI (%), all extract have shown to be endowed by a high antioxidant activity similar to that of BHT. Ethanolic extract of male floral buds showed the highest phenolic and flavonoid concentration and the strongest antioxidant activity. The significant linear correlation was confirmed between the values for the total phenolic content and antioxidant activity of plant extracts. Phenolic compounds were investigated by LTQ Orbitrap LC-MS analysis and revealed 17compounds split into 5 groups: Abscisic acids, phenolic acids and their derivatives, flavonols, flavanones, flavones, flavanols. The high contents of phenolic compounds indicated that these last contribute to the antioxidant activity. The Pistacia vera can be regarded as promising candidates for natural plant sources of antioxidants with high value.

Authors: Thomas Mark P. , Vosko Leah F. , Tucker Eric , Steedman Mercedes , Noack Andrea M. , Grundy John , Gellatly Mary , Leinveer Lisa
Published: December 2019

Employment Standards (es) legislation sets minimum terms and conditions of employment in areas such as wages, working time, vacations and leaves, and termination and severance. es legislation is designed to provide minimum workplace protections, particularly for those with little bargaining power in the labour market. In practice, however, es legislation includes ways in which legislated standards may be avoided, including through exemptions that exclude specified employee groups, fully or partially, from legislative coverage. With a focus on the Ontario Employment Standards Act, this article develops a case study of exemptions to the overtime pay provision of the act and regulations and examines in closer detail three specific areas in which exemptions apply. Through this study of the overtime pay exemption, the system of exemptions is presented as a contradictory approach to the regulation of es that, in effect, reduces es coverage, contributes to the avoidance of key legislated standards, and undermines the goal of providing protection for workers in precarious jobs.

 

La Loi sur les normes d’emploi fixe des conditions minimales d’emploi dans des domaines tels que les salaires, la durée du travail, les vacances et les congés, ainsi que les licenciements et les indemnités de départ. Cette loi vise à fournir une protection minimale sur le lieu de travail, en particulier pour ceux qui ont un faible pouvoir de négociation sur le marché du travail. Cependant, dans la pratique, la Loi sur les normes d’emploi comprend des moyens pour éviter les normes législatives, notamment par le biais d’exemptions excluant totalement ou partiellement certains groupes d’employés de la couverture législative. En mettant l’accent sur la Loi sur les normes d’emploi de l’Ontario, cet article élabore une étude de cas sur les exemptions à la disposition de la loi et de ses règlements sur la rémunération des heures supplémentaires et examine plus en détail trois domaines spécifiques dans lesquels les exemptions s’appliquent. Dans cette étude sur l’exemption des heures supplémentaires, le système d’exemptions est présenté comme une approche contradictoire de la réglementation de la Loi sur les normes d’emploi qui, en réalité, réduit sa couverture, contribue à éviter les normes clés définies par la loi et sape l’objectif de protection des travailleurs qui occupent des emplois précaires.

Published: December 2019

In this work the terahertz spectra of benzene, toluene, p-xylene and styrene–four volatile organic compounds (VOCs) of interest in environmental pollution studies–have been measured in their liquid phase at room temperature using terahertz time-domain spectroscopy (THz-TDS). Their frequency-dependent refractive index and absorption coefficient have been extracted and analyzed in the spectral range from 0.2 to 2.5 THz. The optical properties of bi-component VOCs mixtures have also been investigated and described in terms of a linear combination of pure VOCs optical components.
Optimization of a double-pass scheme for thermal de-phasing compensation in high-power second-harmonic generation
Authors: Sabouri Saeed Ghavami , Khorsandi Alireza
Published: December 2019

The performance of a double-pass scheme is theoretically investigated for the efficiency enhancement of a second-harmonic (SH) beam generated by using a high-power fundamental laser beam. Based on a modified version of coupled equations that include the possible effects leading to the thermal de-phasing, the Collins integral is used for optimizing the focusing optics to obtain maximum efficiency of SH conversion. We found through simulation that at a fundamental power of 40 W, when the focusing regime is set for the loose condition, a conversion efficiency of 74% can be reached. It is possible if the focusing points of the first and second passes are designed to be located at 19 mm and 6 mm away from the input face of the crystal, respectively.

Published: December 2019

This paper addresses one of the key issues in the scientific community of Si photonics: thin-film quality and the light emission properties of band-engineered n+ Germanium-on-Silicon (Ge-on-Si). Compared to the traditional delta doping approach, which was utilized in the first electrically-pumped Ge-on-Si lasers, we offer an n+ Ge-on-Si thin film with better material quality and higher carrier injection efficiency grown by metal-organic chemical vapor deposition (MOCVD). The impacts of thermal cycle annealing and Si substrate offcut on the thin film quality were investigated, including surface roughness, strain, threading dislocation density, Si-Ge interdiffusion, and dopant diffusion. It was revealed that: 1) MOCVD overcomes the outdiffision issue of n-type dopants by having the dopant peaks at the bottom of the Ge films; 2) the characterization of the light emission properties of these MOCVD n+ Ge-on-Si samples (1.0 × 1019 cm−3 doped) compared to delta-doped ultra-high vacuum chemical vapor deposition (UHVCVD) Ge, showing comparable photoluminescence (PL) spectral intensity at 1/4 of the doping level; 3) Detailed PL spectral analyses showed that population inversion from the direct gap transition has been achieved, and the injected electron density in the direct Γ valley is comparable to that of the delta-doped sample even though the n-type doping level is 75% less; and 4) Experimental evidences that Si-Ge interdiffusion has a much larger impact on PL intensity than threading dislocation density in the range of 108-109/cm3. These results indicate that MOCVD n+ Ge is very promising to reduce the threshold of Ge gain media on Si notably.

Published: December 2019

In this paper, the absorption characteristics of a hybrid structure composed of a black phosphorus (BP) nanostrip array based on localized surface plasmon resonance (LSPR) and a metal grating slit structure have been analyzed systematically. Firstly, we theoretically investigate light-matter interaction in different dimensions of BP nanostrip arrays along armchair and zigzag direction, revealing the absorption property and anisotropic plasmonic response. Besides, the transmission characteristics of the metal grating slit structure with different geometric dimensions are thoroughly analyzed by the transmission spectra and electric intensity distributions. At last, by combining the two structures, we increased the absorption of BP from 72% to 83.6% at 7.04 µm, and this hybrid BP structure demonstrates high absorption at mid-infrared wavelength regime, predicting a promising future for the directional dependent plasmonic devices based on two-dimensional (2D) materials.

Published: November 2019

Background and Aim: Periodontitis is the most prevalent inflammatory dental disease caused by a lack of oral hygiene measures in domestic animals. The periodontal disease complex arises as a result of bacterial biofilm deposition termed as plaque on the tooth surface. Lack of cleaning measures either mechanical or chemical credit for the condition. The present study was conducted to screen the animals for the presence of plaque deposition, gingivitis, along with various control measures for the same.

Materials and Methods: Thirty-two dogs of different age groups were evaluated for the presence of plaque and gingivitis by scoring method to estimate the extent of severity. Scaling of the tooth surface was done by ultrasonic scaling machine to remove the plaques, and the animals were divided into four treatment groups to study the effects of dental hygiene chew and chlorhexidine for control of plaque.

Results: Present study revealed 71.87% and 34.37% of the screened animals were having plaque deposition and varied degrees of gingivitis respectively. A positive coefficient of correlation (r) of 0.89 (p<0.05) between advancing age and plaque deposition and 0.85 (p<0.05) between age and level of gingivitis was obtained. Two groups receiving dental chew and 0.2% w/v chlorhexidine showed lower plaque deposits, and the fourth treatment group receiving both dental chew and chlorhexidine showed 100% animals remained free from fresh plaque deposits.

Conclusion: The present study showed a strong positive relationship between age and plaque deposition and gingivitis. The study also showed that oral hygiene measures such as use of dental hygiene chew and chlorhexidine application can reduce plaque deposition and periodontitis in domesticated canines.

Virtue and Proper Use in Plato’s Euthydemus and Stoicism
Authors: Dentsoras Dimitrios
Published: December 2019

The essay examines the description of virtue as a craft that governs the proper use of possessions in Plato’s Euthydemus and Stoicism. In the first part, I discuss Socrates’ parallel between wisdom and the crafts in the Euthydemus, and the resulting argument concerning the value of external and bodily possessions. I then offer some objections, showing how Socrates’ craft analogy allows one to think of possessions as (qualifiedly) good and ultimately fails to offer a defense of virtue’s sufficiency for happiness. In the second part, I examine the Stoics’ craft analogy and note a number of differences from Socrates’ account in the Euthydemus. These include the Stoic claim that external advantages never make any contribution to happiness, even when properly used, and the claim that, unlike other crafts, wisdom does not require any external possessions in order to be exercised and yield benefit and happiness. I then place these differences against the backdrop of the debate regarding virtue’s sufficiency for happiness and argue that the Stoic craft model of virtue fares better than its Socratic antecedent.
The Structure of Plato’s Republic and the Cave Allegory
Authors: Gutiérrez Raul
Published: December 2019

As Plato’s Phaedrus 246c stipulates, every logos must be structured like a living being, i.e., the relation of all its parts to one another and to the whole must be appropriate. Thus, the present paper argues that Plato’s masterwork has been organized in accord with the ascent/descent movement as presented in the Allegory of the Cave: Book I represents eikasia, Books II–IV.434c exemplify pistis, Book IV.434d–444e illustrates dianoia and Books V–VII express noesis. Having reached the anabasis (with the Sun, the Line and the Cave images) the philosopher turns to the consideration of the deficient or unjust forms of the souls and the corresponding political regimes. Finally, the discussion comes back to eikasia through the renewed criticism of mimesis and the exposition of the Myth of Er. As is typical of Plato, this is not merely a formal matter, since the structure conveys that as the Good makes the Ideas intelligible, so the Sun, the Line and the Cave images also throw light on the whole dialogue.
Putting Cosmogony into Words: The Neoplatonists on Metaphysics and Discourse (logos)
Authors: Motta Anna
Published: December 2019

The present paper focuses on some aspects of the Neoplatonist literary-metaphysical theory, which has clearly been expressed in the anony­mous Prolegomena to Plato’s philosophy and further confirmed in Proclus’ exegesis of the Timaeus. Thus, this contribution, examines and compares several passages from the Prolegomena and from Proclus’ Commentary on the Timaeus with a view to showing that it is legiti­mate to speak of a certain cosmogony of the Platonic dialogue that is analogous to that of the macrocosm. Moreover, the analogy between macrocosm and microcosm makes it possible to further investigate the similarity between the λόγος-ζῷον of the Demiurge and that of Timaeus, on the one hand, and the reality which the λόγος expresses, on the other. This similarity turns out to be both structural/morphological and content-related/semantic. Thus, by combining the natural and theo­logical science, the analysis of the “generation” of the macrocosm and microcosm brings out the strongly analogical nature of Plato’s dialogues, which is particularly visible in the Timaeus.
From Democritus to Bertrand Russell and Back
Authors: Motte André
Published: December 2019

Although Bertrand Russell is probably most famous for his “logi­cal atomism,” it is his ethical thought that this article will attempt to contrast with the ethics of the founder of the ancient atomism: Democritus of Abdera. Russell has himself suggested certain affinity here. More concerned with practice than theory, both philosophers advocate a certain teleological and eudemonistic morality; furthermore, they both adopt the same approaches to various related topics. Yet, what had only been outlined by Democritus was extensively developed by Russell. Hence, it is worth examining whether there is any deeper common ground between the two: can Russell’s clarity throw some light on Democritus’ fragments?
Experimental Evaluation of Biomass Medium-Temperature Gasification with Rice Straw as the Fuel in a Bubbling Fluidized Bed Gasifier
Authors: Wang Xiaojia , Zhong Zhenyu , Jin Baosheng
Published: November 2019

Our previous pilot-scale studies (Bioresource Technology 2018, 267: 102–109) preliminarily demonstrated the feasibility of performing air gasification with a novel two-stage system, including a medium-temperature bubbling fluidized bed (BFB) reactor and a high-temperature swirl-flow furnace reactor, using rice husk as the fuel. As an extension of that work, this study aims to further investigate the reaction mechanism and application prospect of this technology in the use of a more representative biomass fuel, i. e. rice straw. The operation stability, flow behaviors and reaction characteristics in the first-stage medium-temperature gasification reactor are studied in a lab-scale BFB gasifier. The effects of important operating conditions on the syngas quality, tar yield, compositions of carbon residue, and risk of agglomeration are elucidated in depth. The results have shown that an increase in the gasification temperature can promote syngas quality, gasification efficiency, and carbon conversion, but also increases the risk of agglomeration. An increase in the gasification equivalent ratio leads to positive effects on the syngas yield, carbon conversion, and tar concentration, but also has negative effects on the syngas heating value, tar yield, and especially the restrain of agglomeration. An increase in the raw material moisture content has negative influence on the gasification performance of rice straw, in terms of the gasification efficiency, carbon conversion, tar yield, and so on. However, the increase of moisture content can reduce the cost of raw material drying, and avoid the fluctuation of bed temperature, and therefore, a practical gasification system is recommended to be designed and operated under a certain conditions with moderate moisture contents.

Published: November 2019

Staphylococcus aureus is gram-positive bacteria that often infect the skin. S. aureus has been experiencing resistance to several antibiotics. One of the solutions to overcome the resistance is by using garlic that is believed by the society can overcome bacterial infection. The study aimed to find out the influence of the variation in concentration of local single clove garlic essential oil used on the inhibition and damage of morphological structure of S. aureus bacteria. The inhibition test was conducted using disc diffusion method. The experiment groups consisted of  1% DMSO as negative control, vancomycin 30µg/ml as positive control and single clove garlic essential oil (25 mg/ml, 50 mg/ml, 75 mg/ml and100 mg/ml) as treatment groups. The diameter of inhibition zone was measured using calipers. The morphological damage of the bacterial cells can be seen using Scanning Electron Microscopy (SEM) with magnification of 25000x. The result of Kruskal-Wallis test analysis indicated that the extract of local garlic essential oil has inhibitory activities against S. aureus bacteria (P<0.05). The damage to the morphological structure of bacterial cells with the administration of 30 µg/ml vancomycin was equal to 100 mg/ml single clove garlic essential oil extract. Single clove garlic essential oil can be used as an alternative treatment for skin infection diseases by inhibiting S. aureus growth.

A kinetic model was proposed for the synthesis of methane to be dimethyl ether (DME) in one reaction step from (CH4 + O2) and (CH3OH) to dimethyl ether using kinetic CuO-ZnO /gAl2O3 catalyst parameters. The bifunctional catalyst of the series kinetic reaction model according to the experimental results obtained under isothermal conditions in a pipe flow reactor under various operating conditions: 225-325 ° C; 10 bar gauge; Residence time, 16-57.0 (g Catalyst) hour (mole CH4) -1. An important step for modeling is the synthesis of methanol from (CH4 + O2) and the synthesis of (CH3OH to DME) is methanol dehydration (very fast), and water-shifting and CO2 (equilibrium) reactions. The effects of water inhibition and CO2 were also taken into account in the synthesis of methanol and the formation of hydrocarbons. The dehydration advantage of methanol can achieve higher yields above 60 % methanol that was converted to DME and the remaining 5% methanol if (CH4 + O2) comes in at 10 bar gauge and 375 ° C. At higher temperatures produces CO2 and H2O. Methane-methanol-DME series reaction model follows single-order gas phase reaction to methane and methanol with k1 = 0.195 minutes-1 and k2 = 0.115 minutes-1 The time and maximum concentration occurs in the formation of methanol constituents 9.5 minutes and 0.44 mole

An optical fiber is a high-speed telecommunication transmission medium. Principally, an optical fiber is made of a very fine glass fiber material, which is able to transmit light waves using light reflection method on the surface of the fiber optics core. An underground installation of the fiber optics makes this device robust from external interferences. However, the fiber optic cable performance should always be checked to maintain performance during data transmission process. One way to test fiber optics cable performance is by using an Optical Time - Domain Reflectometer (OTDR) device. This device sends a light wave from one point of the fiber optics cable. The light wave then returns when reaching the other point of the fiber optic cable while carrying some measurement parameters especially the physical length and attenuation of a fiber optic cable. The evaluation of the fiber optics cable performance requires the preparation, installation, and configuration of the OTDR. In this paper, we conducted evaluation on the performances of fiber optics cable. The data generated by the performed evaluation indicated an occurring attenuation on the fiber optics cable along 64.402 km of its lengths.

Tachometer is an important tool for measuring the rotational speed of electro-mechanical machines and other rotating objects. In a closed-loop system, it should have a mechanism by which sensory instruments must be able to produce and deliver feedback values that can be fetched by the controller. Most commercial tachometers do not have such data communication features, making it difficult to be employed in closed loop systems. This study aims to develop a tachometer which is programmed using calculation on interrupt-based algorithm and has data communication capabilities as well. The algorithm was designed over the minimum features of a microcontroller chip, namely a timer and interrupt. The proposed algorithm that was tested on the prototype results good performance for the typical electro-mechanical machines with a measurement error range between 0.1 and 1.2%. The equation for the calculation of rotation per minute (rpm) has also been revised to provide a more valid formula.

The syngenetic ice and ice-ground composite veins in khasyrey (alas) and interalas plateaus were studied on the second lake-alluvial terrace located in the North of the Gydan Peninsula near the village of Gyda. On the basis of the radiocarbon dating, the time of formation of deposits containing veins from was established – from 16 640 to 854 BP. The peat deposits are mainly represented by the following species: Carex sp., Eriophorum  sp., Betula nana, Equisetum  sp., Calamagrostis  sp., Vaccinium vitis-idaea, Drepanocladus  sp., Empetrum sp., Vaccinium uliginosum, Rubus arcticus, Petasites sp. It is established that the polygonal-veined ice of khasyrey and interalas plateaus, except for vertical-striped «clean» ice, contain areas with vertical wavy streaks of ice-ground. Ice of elementary veins and segregation ice were revealed in the composition of veins according to structural and textural features in polarized light. Elementary ice veins compose «clean» ice sections of veins and segregation ice which are their ice-ground sections. Elementary veins are indicative of the predominance of the process of frost cracking during the formation of polygonal-vein ices. The presence of inclusions of ice-ground in the structure of veins points is evidence of a manifestation of local thermokarst processes under the growth of polygonal-vein ice. Ice-ground veins were formed by repeated thawing of the initial ice veins. The formation of ice-ground veins during syngenetic freezing of sediments of the second lake-alluvial terrace is related to uneven manifestation of thermokarst in different facies situations and and climate changes at the Early Pleistocene and Holocene.
Effect of thaws on snow cover and soil freezing under the contemporary climate change
Authors: Sosnovsky A. V. , Osokin N. I.
Published: December 2019

Thaw and liquid precipitation retard cooling of snow cover and soil surface and so may be a factor of heating. This slows down the soil freezing due to more active freezing of the wet snow, and, thus, promotes cooling and re-cooling of the soil. However, there are a number of factors which intensify the soil freezing after thaw. With thaw, the thickness of the snow cover decreases, and its density increases. In addition, after freezing wet snow improves the contact between the ice crystals, which increases the hardness and thermal conductivity of the snow. As a result, after the thaw, the thermal protection ability of the snow decreases, and this can accelerate freezing of the soil. The dynamics of snow accumulation in Russia is considered in the paper. Using data obtained in the Western Svalbard, we demonstrate the increase in the number of thaws and liquid precipitation and influence of them on the snow cover and soil freezing. The influence of thaw on the growth of thermal resistance of snow cover is also considered. Calculations have shown that in the absence of a thaw, the depth of soil freezing is 1.26 m. With a thaw lasting 10 days, which begins on the 40th day from the start of soil freezing, the depth of freezing is reduced down to 1.2 m without considering changes in snow cover. When taking into account changes in the thermal resistance of snow cover, the depth of soil freezing by the end of the cold period increases up to 1.32 cm. With a thaw in the mid-winter, i.e. on the 70th day, the depth of freezing decreases down to 1.22 m, that is smaller than the depth of freezing without thaw. This scenario is in accordance with changes in snow accumulation dynamics under the present-day climate, as in many areas most of the solid precipitation falls in the first half of the cold period. As a result, for a period after a thaw the smaller volume of snow will be deposited, and this will retard increasing in thermal resistance of the snow cover

Published: December 2019

Recibido 30 de marzo de 2012 •  Corregido 17 de setiembre de 2012 • Aceptado 07 de noviembre de 2012Este artículo resume los resultados de una investigación cualitativa cuyo objetivo es analizar el papel de la maestra en la promoción del conocimiento y el manejo de las propias emociones de un grupo de  niñas y  niños  de  un quinto grado escolar como competencias de la inteligencia emocional. Este estudio resultó relevante en la medida en que, desde el ámbito de la psicopedagogía,  se propone romper con el papel tradicional del personal docente centrado exclusivamente en la transmisión de conocimientos, que ha dejado de lado la dimensión de apoyo emocional que  tanto necesitan las personas. Se evidenció en las niñas y los niños un pobre vocabulario emocional, dificultad para identificar algunas emociones y para diferenciarlas. Esto se refleja en una limitación para tomar conciencia de sus propias emociones y en la dificultad para controlarlas. Por otra parte, se demuestra la importancia de potenciar habilidades emocionales del estudiantado, como una tarea primordial en los centros educativos, en los cuales la persona docente desempeña un papel fundamental como modelo y promotora de la inteligencia emocional.
Pedagogía contestataria: propuesta para enfrentar las relaciones de poder en el escenario educativo
Authors: Robles Murillo Keylor
Published: December 2019

El presente ensayo tiene como objetivo principal compartir reflexiones en torno a la importancia del desarrollo de una pedagogía contestataria. Esta propuesta se fundamenta desde cinco aristas: a) epistemología, b) ontología, c) axiología, d) teleología y e) metodología. Cabe mencionar que dicha pedagogía surge a partir de la perspectiva en donde, se concibe a la educación como un producto sociocultural, y a su vez, como una alternativa para visibilizar y deconstruir las relaciones de poder que surgen en la sociedad. Finalmente, se espera que los aportes brindados puedan incidir positivamente, en las relaciones educativas con el fin de convertir la educación en un medio para lograr la transformación social.
¡No queremos que nos vendan al Ecuador! Un intento de golpe de Estado en la Costa Rica del siglo XIX
Authors: Corella Ovares Esteban Corella Ovares
Published: December 2019

El artículo analiza el intento de golpe de Estado realizado por el general Manuel Quirós contra Juan Rafael Mora. Este alzamiento fracasó porque el general no fue capaz de movilizar a suficientes hombres como para tomar el cuartel de San José, a pesar de que intentó convencer a los milicianos mediante el rumor de que el gobierno de Mora los obligaría a luchar por Juan José Flores, expresidente de Ecuador que se encontraba en el país en ese momento. El episodio sirve de excusa para examinar los medios utilizados por los miembros de la élite para movilizar a los milicianos que formaban la mayor parte de las fuerzas armadas de Costa Rica a mediados del siglo XIX.

IV Antibiotic Durations for NontyphoidalSalmonellaBacteremia
Authors: Hess Lauren M. , Burdick Bethany , Minard Charles G. , Dutta Ankhi
Published: December 2019

OBJECTIVES:

The objective was to determine if shorter intravenous (IV) antibiotic (<7 days) for nontyphoidal Salmonella bacteremia (NTS-B) is noninferior to longer (≥7 days) in terms of 30-day emergency department (ER) or rehospitalization in healthy children.

METHODS:

A retrospective observational study of otherwise healthy children admitted to a children’s hospital in the United States from 2006 to 2017 with NTS-B was conducted.

RESULTS:

Of 231 patients reviewed, 51 patients had NTS-B. Median IV duration for all patients was 5 days (range 2–17 days). The short-duration group (SDG) (<7 days; N = 32) had a median of 4 days (range 2–6 days) of IV antibiotics versus a median of 9 days (range 7–17 days) in the long-duration group (LDG) (≥7 days; N = 19). The hospital length of stay in the SDG was 3.5 days versus 7 days in the LDG (P < .001). The SDG was significantly noninferior to the LDG in terms of ER visits or hospital readmissions within 30 days (absolute risk difference 5.3%; 95% confidence interval −16% to −5%), with only 1 child in the LDG returning to the ER.

CONCLUSIONS:

IV antibiotic durations for NTS-B in otherwise healthy children were variable within our study group. Shorter courses (<7 days) of IV antibiotics were noninferior to longer courses in healthy children and reduced hospital stay. ER visits and readmissions were rare, and there was no association between IV treatment duration and risk of relapse. Prospective studies are needed to study the safety of shorter courses, but given the absence of evidence favoring longer courses, shorter courses can be considered.
Renal Replacement Therapy in Neonates
Authors: Spector Benjamin L. , Misurac Jason M.
Published: December 2019

Acute kidney injury (AKI) is a highly prevalent disease entity in the NICU, affecting nearly one-quarter of critically ill neonates by some reports. Though medical management remains the mainstay in the treatment of AKI, renal replacement therapy (RRT) is indicated when conservative measures are unable to maintain electrolytes, fluid balance, toxins, or waste products within a safe margin. Several modalities of RRT exist for use in neonatal populations, including peritoneal dialysis, hemodialysis, and continuous RRT. It is the aim of this review to introduce each of these RRT modalities, as well as to discuss their technical considerations, benefits, indications, contraindications, and complications.
