Authors: Akdogan Muberra , Ustundag Yasemin , Akdağ Arzu , Neselioglu Salim , Erel Ozcan
Published: March 2019

Purpose:

This study was performed to determine whether one drop of topical administration of Coqun® (Coenzyme Q10 and Vitamin E)-a potent antioxidant-twice a day has any effect on the thiol-disulphide homeostasis-a novel oxidative stress marker in the Retinopathy Of Prematurity (ROP) disease course.

Methods:

This was a prospective observational study comprising 28 infants with ROP at stage 2 and higher who followed up at the paediatric intensive care unit. Ferric reducing power of plasma (FRAP), albumin, ischemia-modified albumin (IMA) and thiol disulphide homeostasis levels were studied in the infants before and two weeks after Coqun® treatment.

Results:

The mean gestational age was 27 (24–32) weeks, the mean birth weight was 1,012±326 g and the mean duration of care in an incubator was 64±23 days. FRAP levels were 0.91±0.17 μmol/L, IMAs were 0.85±0.29, native thiols were 248±38.9 μmol/L and total thiols were 284±39.2 μmol/L, respectively, at the beginning of therapy.

FRAP levels 0.79±0.21(p= 0.006) μmol/L, IMAs 0.73±0.36(p = 0.096), native thiols 262±42.6(p = 0.164) μmol/L and total thiols 291±43.6(p = 0.344) μmol/L showed no difference after two weeks of therapy.

Conclusion:

Thiol disulphide homeostasis levels do not change with Coqun® therapy during ROP course.

Authors: Sharma Rashmi , Sharma Pramod Kumar , Malviya Rishabha
Published: March 2019

Biochemical applications of polysaccharide are often demonstrated in various drug delivery systems and bone tissue engineering. Perhaps they are similar in biochemical properties with human components of the extracellular matrix, the body recognized them easily. In this manuscript, the polysaccharides, such as chitosan chitin, carrageenan, chondroitin sulfate,and cellulose used as scaffolds for bone regeneration, are discussed. Scaffolds have a porous structure which is extremely interconnected & permits cell penetration. They provide a 3-dimensional environment for bone regeneration. Polysaccharides such as chitosan have great mechanical characteristics and biocompatibility. Present manuscript deals with the polysaccharides based scaffolds that should possess osteoconductivity, biocompatibility,and mechanical strength like property during the tissue repairing process.They also show decreased degradation rate which means that they are present for tissue regeneration for an extended period of time. So it can be concluded that the polysaccharide-based scaffolds have good mechanical strength and stimulate the natural extracellular of bone for the regeneration process. In this manuscript, various patentsbased on applications of polysaccharide in bone marrow and tissue regeneration is also included.

Authors: Rymarchuk Mariiana , Vakaliuk Liubomyr
Published: March 2019

Nowadays the development of a modern information society, the intensity of accumulating the latest professional information and systematic obsolescence of professional knowledge necessitate a constant and continuous learning of a 21st-century specialist. The transition to lifelong learning, when basic education is periodically subjected to additions and adjustments that requires graduates of higher education institutions to master professional knowledge, as well as to form social and professional mobility, is now recognized by the analysts as a solution of this problem. According to researchers, social and professional mobility of health specialists consists in their ability to overcome stereotypes, assimilate new technologies and solve professional problems in accordance with modern socio-cultural and economic conditions. In Ukraine, the development of social and professional mobility of future health specialists is directly related to the implementation of the system of continuous professional development of health professionals. The introduction of the problem-solving techniques during postgraduate study enhances the professional training of doctors, that, in its turn, will allow them to effectively use knowledge gained in daily practice. Interactive methods such as case method, role playing games, management games, brainstorming, disputes, discussions, critical incident techniques, project-based learning, competitive learning, small-group learning with elements of management game or carousel strategy, method of interdisciplinary conference with elements of discussion are considered as an effective tool for problem-based learning within health professional education. Thus, the contribution of postgraduate education to the provision of continuous professional development of health professionals creates optimal conditions for the formation of social and professional mobility of health specialists.
A Revision Arthrodesis of Severe Charcot Foot with Intramedullary Nail: a Case Report and Literature Review
Authors: Zaizi Abderrahim , Benomar Hicham Ahmed , Bakayan Mohamed Said , Krimch Omar , Lamrani Moulay Omar , Berrada Mohammed Saleh
Published: March 2019

Diabetic Charcot foot is characterized by varying degrees of bone and joint disorganization secondary to underlying neuropathy, perturbations of bone metabolism and trauma. Offloading is the most important initial treatment recommendation. Surgery can be helpful in early stages involving acute fractures of the foot or ankle or in later stages when offloading is ineffective. Incorrect diagnosis and improper treatment often result in the extremity having to be amputated.

 

 

There are several surgical procedures accepted in Charcot foot surgery. Their goal is to obtain a plantigrade foot and prevent recurrent ulcerations. Arthrodesis is a well-known surgical procedure that addresses severe joint derangement through a surgically induced bony fusion. In Charcot foot, arthrodesis is usually indicated when there is significant skeletal instability. This procedure can be done by internal or external fixation.
Capacidades científicas en el Trastorno del Espectro Autista en México: reflexiones desde el vínculo entre ciencia, tecnología e innovación y políticas sociales
Authors: Anzaldo Montoya Mónica , Cruz Ruiz Laura Patricia
Published: March 2019

En el campo de los estudios sobre ciencia, tecnología y sociedad prevalece la discusión acerca de cómo direccio­nar las capacidades científicas a las necesidades sociales. Una problemática escasamente considerada como ámbito de orientación del conocimiento, son las necesidades de las personas con autismo y sus familias. El autismo afecta a 1 de cada 160 niños a nivel mundial y es la condición de mayor prevalencia en el ámbito psiquiátrico. México care­ce de políticas de CTI que articulen las necesidades de esta población. Este trabajo aporta un primer análisis de las capacidades científicas y la financiación pública dedicado al tema por el período de 1985-2018. A partir de herra­mientas bibliométricas y datos empíricos, se encontró un campo de investigación rezagado en producción académi­ca, pero se identifica una comunidad creciente y vinculada con actores sociales y empresas privadas. Finalmente, se ofrecen recomendaciones para conformar una agenda de investigación.
La violencia hacia los hombres en la pareja heterosexual: una revisión de revisiones
Authors: Rojas-Solís José Luis , Guzmán-Pimentel Mayte , Jiménez-Castro Margarita Paloma , Martínez-Ruiz Laura , Flores-Hernández Bibiana Gabriela
Published: March 2019

La violencia hacia la pareja cometida por mujeres hacia hombres es un fenómeno al que en muchos contextos aún no se le considera existente, ni importante y mucho menos un problema social. Esto ha provocado diversas di­ficultades en su estudio. Por tal razón, se presenta una re­visión bibliográfica realizada sistemáticamente en la que se seleccionó y analizó doce revisiones teóricas o sistemáticas, publicadas entre los años 2001 y 2018, obtenidas a tra­vés de bases de datos como Google Académico, EBSCO, SCOPUS, Web of Science, Science Direct, Wiley y Springer Link. El objetivo ha sido analizar los factores so­cioculturales asociados a la violencia hacia el hombre, sus recursos, sus repercusiones y las razones de permanencia de las víctimas en esa relación. Entre los resultados se destaca la existencia y el tipo de violencia sufrida por los hombres, que en su mayoría es de tipo psicológico; el rol que des­empeña la idea de masculinidad en los varones, lo que di­ficulta el reconocimiento de que son víctimas de violencia; así como la ausencia de recursos para la atención de estos varones. La literatura científica y académica sobre el tema aún sigue siendo limitada y prácticamente inexistente en regiones como América Latina. Por ende, sería pertinente realizar más investigaciones sobre la victimización de los hombres en parejas heterosexuales para obtener un cuadro más completo e integral sobre el fenómeno de la violencia interpersonal en la pareja heterosexual.
La razón creadora: presencia de la filosofía en la obra poética de Manuel del Cabral
Authors: De los Santos Domingo
Published: March 2019

Partiendo de la tesis de que tanto la poesía como la filoso­fía son hijas de una misma razón creadora, es decir, en am­bos casos está, ya sea de manera implícita o explícita una racionalidad, presentamos el presente ensayo que analiza el pensamiento filosófico contenido en la obra poética de Manuel del Cabral. El propósito es mostrar cómo en este autor la poesía y la filosofía van de la mano, constituyén­dose así en uno de los principales pensadores dominicanos, caracterizado por la profundidad de sus ideas y la belleza expresiva con que las presenta. Para la realización de dicho estudio se procedió al análisis hermenéutico de su poesía, relacionándola con los grandes temas que trata la filosofía: la muerte, la belleza, el amor, el sufrimiento, el bien, el mal, la justicia, el conocimiento y la condición humana. En Manuel del Cabral encontramos como hallazgos im­portantes una visión ética que abarca el grito por las injus­ticias, la solidaridad con el necesitado, la pequeñez y mise­ria del ser humano, el asombro ante el infinito y la libertad siempre frágil. Para lograr esto ha sido necesario analizar las obras Compadre Mon, Manuel cuando no es tiempo, De este lado del mar, Sangre mayor, Chinchina Busca el tiempo, Los huéspedes secretos, Pedrada planetaria, Trópico negro, 14 mudos de amor, La espada metafísica.
Microstructural investigation of the coatings prepared by simultaneous aluminizing and siliconizing process on γ-TiAl
Authors: Nouri S. , Azadeh M.
Published: March 2019

In this research, formation of aluminide/silicide diffusion coatings on ?-TiAl[Ti-48Al-2Nb?2Cr (at.%)] alloy using gasphase diffusion pack cementation process has been investigated. The application of powder mixtures with various chemical compositions in the pack cementation process performed at 1000oC for 6 hours in order to achieve simultaneous diffusion of Al and Si, showed that the composition of the powder mixture could have a significant effect on the structure and thickness of the aluminide/silicide coatings. The identification and analysis of aluminide/silicide microstructures formed as a result of simultaneous diffusion of Al and Si, which was comprehensively and qualitatively done for the first time in this study, showed that the sequential mechanism is dominant in the formation of the above-mentioned coatings. Furthermore, Kirkendall phenomenon and volumetric changes caused by the formation of Ti5Si3 and Ti5Si4, were considered as the two dominant mechanisms in the formation of porous segregated structure in these coatings. In this study, the effect of decreasing the activity of Si, through two approaches of reducing the amount of Si in the powder mixture and using Al- 20wt.%Si alloyed powder instead of pure Al and Si depositing elements, on the microstructural modification coatings was investigated. The results showed that reducing the Si activity at the surface of the coating and, consequently, reducing the flux of active silicon atoms (JSi), has a significant effect on the formation of coating with an ideal structure.

The isothermal section of the Ni-Mn-Sb ternary system at 773 K was measured by means of 117 alloys which were analyzed by using X-ray diffraction (XRD), scanning electron microscopy (SEM), energy dispersion spectroscopy (EDS), and electron probe microanalysis (EPMA) techniques. The existence of 7 binary compounds, namely NiMn, Mn2Sb, MnSb, NiSb2, NiSb, Ni5Sb2, Ni3Sb and 2 ternary compounds, namely Ni2MnSb and NiMnSb were confirmed for this isothermal section. The four binary compounds Ni3Sb (Cu3Ti structure, Pmmn space group), Ni5Sb2 (Ni5Sb2-type structure, C2 space group), NiSb2 (FeS2-type structure, Pnnm space group) and Mn2Sb (Cu2Sb-type structure, P4/nmm space group) in the binary systems Ni-Sb and Mn-Sb were stoichiometric compounds, the homogeneity ranges of which were negligible. However the five single phases in the Ni-Mn system and the two binary compounds MnSb and NiSb showed more or less homogeneity ranges formed by substitution of Mn and Sb for Ni atom. The Heusler compound ? (Ni2MnSb) has L21-type ordered structure with space group Fm-3m, a = 0.6017 nm. And the crystal structure for the Half-Heusler compound ? (NiMnSb) is C1b-type (F-43m) with a = 0.5961 nm. The approximate homogeneity ranges of the two ternary compounds ? and ? at 773 K were investigated.

Published: March 2019

Introduction/Objective. The wider literature review of analysis in levels of catalase (CAT) or superoxide dismutase (SOD) enzymes in type 2 diabetes mellitus (T2DM) patients shows no pronounced consistency. We have assumed that the onset of diabetes does not significantly change individual quantities of these enzymes, but instead it changes the relationship of these enzymes. Methods. The study consisted of four groups (n = 30 for each group): obese individuals with disturbed glucose metabolism (subjects with newly diagnosed T2DM) before and after metformin treatment initiation, obese subjects with normal glucose tolerance (NGT) and a control group of healthy normal weight subjects. Appropriate anthropometric measurements and laboratory tests of biochemical parameters and antioxidative enzymes were carried out in all participants. Results. Our study has confirmed that correlation of enzymes CAT and SOD is significantly changed in patients with newly diagnosed T2DM, and that it can be restored by reestablishment of glucose homeostasis with adequate antidiabetic treatment. Conclusion. The applied therapy restores the dynamic balance of CAT and SOD, mainly through the reintegration of the new equilibrium in the enzyme system after achieving better glycemic control. These conclusions are only valid in the initial stages of T2DM treatment.

Community and Individual in the Vortex of Changes. Limited Time Travel with a Calvinist Spirit.
The paper aims to touch upon practical theological issues which refer to a particular country, era, and theological area, namely, to the practical theology pursued at the theological institutions and universities of the Dutch Protestant Church in the second part of the 20ᵗʰ century. The study aims to shed light on practical theologians such as K. A. Schippers (ThUK) and J. Hendriks (VU Amsterdam) who have been and remain integral in their own time and in their respective field of expertise. Moreover, the study also focusses on the most famous Dutch sociologist, G. Dekker (VU-Amsterdam). We also seek to highlight those aspects from the work of these authors which should necessarily be implemented into the practical theological curriculum of the Hungarian-language reformed universities and thereby we would like to link this contribution to the significant practical theological oeuvre of Dr. Sára Bodó.
Hogyan kerültek kalotaszegi varrottasok a királylány kelengyéjébe?
Authors: PÜSÖK Sarolta
Published: March 2019

Why Are There Traditional Embroideries from Călata Region (Kalotaszeg) in the Dowry of a Princess?[1]
The study has three major units:

A) Protestantism and social engagement. In the Hungarian Protestantism it is common and a tradition to be socially engaged. One can’t be indifferent in the case of social issues, but has to declare God’s glory in the world through having a responsible approach to their community in social, economic and cultural respects.
B) The culture-historical role of pastor’s families. The walls of a manse are made of glass – as the Hungarian saying says the life of the pastor and their family has always been interesting to the outer world. After the period of illuminism, but more in the 19th century the residents of the manse consciously assumed the role of being an example. They readily undertook the duty of social organisation, the one of spreading culture, and educating the people.
C) The exemplary voluntary work of Gyarmathy Zsigáné. The lady presented in the study was born in the middle of the 19th century as a pastor’s daughter, with her husband they have coordinated and made a considerable contribution to the cultural, social life of Călata (Kalotaszeg) region in Transylvania. She took the beautiful handmade embroideries sewed by the countrywomen to world fairs, and promoted this kind of traditional craft through her assiduous publicistic work. She formed friendships with painters, ethnographers, fashion designers, won the support of noble women from around Europe, using her network she popularized the embroideries, so they reached America, queens in European royal courts, Parisian, Viennese salons. With her writings she aided the picturesque but dismally poor region with waking demand for the embroideries, so opening the door to home-industry, which was almost life-saver for the country- This helped not only to lessen the economic hardship, but also to save the values of folk art from sinking into oblivion, this way the techniques and the pristine patterns have been passed on to the coming generations and they can still be admired as a decoration of many reformed churches in Călata region (Kalotaszeg).

Is it happy to work with leaders viewing their work as a calling?
Authors: Park Jiyoung , Sohn Young Woo
Published: March 2019

Although scholars have paid increasing attention to people with callings, relationships between leader's calling and follower's job attitudes have been understudied. The purpose of this study was to investigate the relationship between leader calling and follower job satisfaction, and mediators and a moderator on the relationship. We hypothesized that leader calling would be positively related to follower job satisfaction via follower's perceived transformational leadership and occupational self-efficacy and that the two mediators would be positively related. As a boundary condition, we tested a moderating role of job crafting on the positive relationship between leader calling and follower occupational self-efficacy. To examine the hypotheses, we conducted two survey studies using a sample of 242 Korean working adults (Study 1)　and a sample of 221 American working adults in diverse industries (Study 2). We found a positive relationship between leader calling and follower job satisfaction (Study 1) and a significant mediating effect of transformational leadership on the relationship (Studies 1, 2). In both studies, follower occupational self-efficacy mediated the link between transformational leadership and follower job satisfaction rather than directly mediating the relationship between leader calling and follower job satisfaction. Also, when followers were highly involved in job crafting (Study 1) and cognitive crafting (Study 2), their occupational self-efficacy did not vary depending on the level of leader calling. Interestingly, the relationship between leader calling and follower occupational self-efficacy was negative when followers showed low levels of job crafting and cognitive crafting. We discuss the implications of these results, study limitations, and practical suggestions for future research.
The effect of supervisor’s characteristics on impression management and the moderation effect of perception of organizational politics
Authors: Choi ARam , Yoo TaeYong
Published: March 2019

The purpose of this study was to investigate the effect of supervisor’s characteristics on impression management and the moderation effect of perception of organizational politics. Using the survey research method, data were collected from 296 employees who were working in a variety of organizations in Korea. As results, supervisor’s power distance orientation, social face sensitivity, and agreeableness had positive relationships with supervisor’s impression management, and supervisor’s neuroticism had negative relationship with supervisor’s impression management. However, supervisor’s extraversion did not have significant relationship with supervisor’s impression management. The perception of organizational politics had moderation effect on the relationship between supervisor’s agreeableness and impression management. That is, the positive relationship between supervisor’s agreeableness and impression management was stronger when the perception of organizational politics was high rather than low. On the other hand, moderation effects of the perception of organizational politics on the relationship between supervisor’s power distance orientation, social face sensitivity, extraversion, neuroticism and impression management were not significant. Based on these results, we discussed the implications and limitations of the study, and the suggestions for the future research.

OBJECTIVE

To determine whether an enrofloxacin–silver sulfadiazine emulsion (ESS) labeled for treatment of otitis externa in dogs has ototoxic effects in rabbits following myringotomy.

ANIMALS

6 healthy adult New Zealand White rabbits.

PROCEDURES

Rabbits were anesthetized for brainstem auditory-evoked response (BAER) tests on day 0. Myringotomy was performed, and BAER testing was repeated. Saline (0.9% NaCl) solution and ESS were then instilled in the left and right middle ears, respectively, and BAER testing was repeated prior to recovery of rabbits from anesthesia. Application of assigned treatments was continued every 12 hours for 7 days, and rabbits were anesthetized for BAER testing on day 8. Rabbits were euthanized, and samples were collected for histologic (6 ears/treatment) and scanning electron microscopic (1 ear/treatment) examination.

RESULTS

Most hearing thresholds (11/12 ears) were subjectively increased after myringotomy, with BAER measurements ranging from 30 to 85 dB in both ears. All day 8 hearing thresholds exceeded baseline (premyringotomy) values; results ranged from 30 to 85 dB and 80 to > 95 dB (the upper test limit) in saline solution–treated and ESS-treated ears, respectively. All ESS-treated ears had heterophilic otitis externa, epithelial hyperplasia of the external ear canal, various degrees of mucoperiosteal edema, and periosteal new bone formation on histologic examination. Scanning electron microscopy revealed that most outer hair cells in the ESS-treated ear lacked stereocilia or were absent.

CONCLUSIONS AND CLINICAL RELEVANCE

Results supported that ESS has ototoxic effects in the middle ear of rabbits. Further research is needed to confirm these findings. Myringotomized laboratory rabbits may be useful to study ototoxicity of drugs used in human medicine.

Published: March 2019

OBJECTIVE

To determine whether differences existed in the viscoelastic properties of synovial fluid samples from the metacarpophalangeal, intercarpal, and distal interphalangeal joints of orthopedically normal athletic horses.

ANIMALS

45 warmblood horses and 30 Thoroughbreds (age range, 4 to 16 years).

PROCEDURES

Synovial fluid samples were aseptically obtained via arthrocentesis from 1 metacarpophalangeal, intercarpal, and distal interphalangeal joint of each horse, and nucleated cell counts were performed. A commercial ELISA was used to measure sample hyaluronic acid concentrations, and full rheological characterization of samples was performed to measure the elastic or storage modulus G' and viscous or loss modulus G“ at 37.5°C (representing the body temperature of horses). Findings were compared among joints and between breed groups by means of ANOVA.

RESULTS

Significant differences in synovial fluid G' and G“ values were identified between Thoroughbreds and warmblood horses for the metacarpophalangeal joint, between the metacarpophalangeal and intercarpal joints of Thoroughbreds, and between the metacarpophalangeal and distal interphalangeal joints and intercarpal and distal interphalangeal joints of warmblood horses. No significant differences were identified between breed groups or among joints in synovial fluid hyaluronic concentrations or nucleated cell counts.

CONCLUSIONS AND CLINICAL RELEVANCE

Viscoelastic properties of the forelimb joints of orthopedically normal Thoroughbreds and warmblood horses differed within and between these 2 groups, mainly as a function of the evaluated joint. To the authors' knowledge, this was the first study of its kind, and additional research is warranted to better understand the viscoelastic properties of synovial fluid in horses to optimize their locomotive function.
Usefulness of focused cardiac ultrasonography for predicting fluid responsiveness in conscious, spontaneously breathing dogs
Authors: Oricco Stefano , Rabozzi Roberto , Meneghini Caterina , Franci Paolo
Published: March 2019

OBJECTIVE

To evaluate the diagnostic usefulness of focused cardiac ultrasonography and selected echocardiographic variables for predicting fluid responsiveness in conscious, spontaneously breathing dogs with various clinical conditions.

ANIMALS

26 dogs (15 males and 11 females) with a median age of 84 months (range, 12 to 360 months) and median body weight of 8 kg (range, 2 to 35 kg) referred for various clinical conditions.

PROCEDURES

Left ventricular end-diastolic internal diameter normalized to body weight (LVIDDn), left ventricular volume score (LVVS), left ventricular end-diastolic volume index (EDVI), aortic velocity time integral (VTIAo), and aortic peak flow velocity (VmaxAo) were echocardiographically measured before and after IV administration of a bolus of lactated Ringer solution (4 mL/kg) over a 1-minute period. Dogs were classified on the basis of the observed change in aortic stroke volume following fluid administration as responders (≥ 15%) or nonresponders (< 15%) to fluid administration. Receiver operating characteristic curves were generated for the ability of LVVS, LVIDDn, EDVI, VTIAo, and VmaxAo to predict responder status.

RESULTS

13 dogs were classified as responders and 13 as nonresponders. Areas under the receiver operating characteristic curves (95% confidence intervals) for predicting fluid responsiveness were as follows: VTIAo, 0.91 (0.74 to 0.99); LVIDDn, 0.85 (0.66 to 0.96); EDVI, 0.85 (0.65 to 0.96); LVVS, 0.85 (0.65 to 0.96); and VmaxAo, 0.75 (0.54 to 0.90).

CONCLUSIONS AND CLINICAL RELEVANCE

The evaluated echocardiographic variables were useful for noninvasive prediction of fluid responsiveness in conscious dogs and could be valuable for informing clinical decisions regarding fluid therapy.

Published: March 2019

OBJECTIVE

To assess liver and spleen stiffness in healthy dogs by use of a novel 2-D shear wave elastography (SWE) technique and to investigate the repeatability and reproducibility of the technique.

ANIMALS

8 healthy adult Beagles.

PROCEDURES

2-D SWE was performed on each dog to assess liver and spleen stiffness. Repeatability (intraday variability) and reproducibility (interday variability) of 2-D SWE were investigated. For all 8 dogs, 2-D SWE was performed 3 times in 1 day (4-hour intervals) and on 3 separate days (1-week interval). Data were expressed as mean ± SD values for shear wave velocity and the Young modulus in the liver and spleen. Intraday and interday coefficients of variation were assessed for all variables.

RESULTS

Mean ± SD shear wave velocity obtained for the liver and spleen was 1.51 ± 0.08 m/s and 2.18 ± 0.27 m/s, respectively. Mean value for the Young modulus obtained for the liver and spleen was 6.93 ± 0.79 kPa and 14.66 ± 3.79 kPa, respectively. Elasticity values were significantly higher for the spleen than for the liver. Intraday and interday coefficients of variation for all variables were < 25% (range, 3.90% to 20.70%).

CONCLUSIONS AND CLINICAL RELEVANCE

2-D SWE was a feasible technique for assessing liver and spleen stiffness of healthy dogs. Future studies on the application of 2-D SWE for dogs with chronic hepatitis, cirrhosis, and portal hypertension are needed to evaluate the clinical applicability of 2-D SWE.
In vitro evaluation of a medial approach for intra-articular injection of the tarsometatarsal joints of horses
Authors: Canonici Paolo , Beccati Francesca , Canonici Fernando , Pepe Marco
Published: March 2019

OBJECTIVE

To develop a reliable method for injection of the tarsometatarsal (TMT) joint of horses through a medial approach and to characterize anatomy of the synovial recesses of the TMT joint with CT.

SAMPLE

13 pairs of fresh cadaveric equine tarsi.

PROCEDURES

TMT joints were assessed with radiography and CT. Twelve pairs of TMT joints were assigned to an experienced veterinarian (8 joints) or veterinary student (16 joints) for injection with contrast medium through a medial or a lateral approach. Every TMT joint was then reexamined radiographically and with CT to assess diffusion of contrast medium. The number of attempts for the lateral and medial approaches between and within investigators was evaluated, which included evaluation of the diffusion of contrast solution in relation to the approach used.

RESULTS

All 24 TMT joints were successfully injected, as confirmed with radiography and CT. There was no significant difference in the number of attempts between the medial and lateral approaches and between investigators. No significant difference was detected in the distribution of contrast medium in each synovial recess between the medial and lateral approaches.

CONCLUSIONS AND CLINICAL RELEVANCE

The medial approach described here for injection of the TMT joint of horses was highly reliable. It involved use of an easily palpable anatomic landmark on the mediodistal aspect of the TMT joint. An established alternative method for injection of the TMT joint may be useful in clinical practice for diagnostic and therapeutic purposes, although a medial approach may increase risk of injury to veterinarians.
Glucose meters: What’s the laboratory reference glucose?
Authors: Carta Mariarosa , Giavarina Davide , Paternoster Andreina , Bonetti Graziella
Published: March 2019

Background

The accuracy of glucose meters is evaluated by comparing their results with those from a reference laboratory glucose analyser. The main scientific societies recommend the use of a prompt glycolysis inhibitor such as citrate for an accurate glucose determination. In the present preliminary study, we discuss the bias between capillary and plasma glucose measured concentrations, determined in two Italian clinical laboratories, using tubes containing an NaF and citrate mixture in liquid and granular form.

Methods

139 volunteers in whom 75 g OGTT was requested were recruited. Basal capillary glucose was determined using Abbott FreeStyle Precision Neo in Brescia (n=63), while clinical laboratory reference P-glucose was determined using tubes containing NaF/K3EDTA and liquid NaF/Na2EDTA/citrate. Basal capillary glucose was determined using a Roche Cobas Accu-Chek Inform II in Vicenza (n=76), while P-glucose was determined using tubes containing NaF/K2Ox and NaF/Na2EDTA/citrate in granulated form. Reference P-glucose was determined with a hexokinase method on Dimension Vista systems. Differences between capillary and reference P-glucose were evaluated according to ADA/ISO 15197:2013 specifications.

Results

96.82% and 97.37% of capillary determinations were within specifications when liquid and granular citrate mixture tubes were used, respectively. Conversely, only 73.02% and 80.26% of determinations were within criteria using NaF.

Conclusions

It’s important to know what is the laboratory reference glucose in evaluating glucose meters’ accuracy. The evaluation of glucometers’ accuracy with respect to a reference laboratory may be wrong if tubes containing only NaF are used due to in vitro glycolysis. Only tubes containing citrate mixture permit the correct evaluation of glucose meters’ accuracy.
Body mass index and C-reactive protein are potential predictors of asthma development in Egyptian polycystic ovary syndrome patients
Authors: Nasser Hebatallah Ahmed , Ezz Nermeen Zakaria Abuel , Abdel-Mageed Heidi Mohamed , Radwan Rasha Ali
Published: March 2019

Background

Recent studies suggest asthma prevalence in polycystic ovary syndrome (PCOS) patients. This is the first study to explore asthma prevalence among Egyptian PCOS patients. It highlighted common findings in PCOS and asthma. It investigated whether these findings could serve as potential predictors of asthma.

Methods

A hundred PCOS patients, sixty asthmatic patients and thirty apparently healthy females of matched age were included. Body mass index (BMI), C-reactive protein (CRP), IL-6, IgE, 25 (OH) vitamin D, testosterone and lipid profile were measured.

Results

Both PCOS and asthmatics had significantly higher BMI, Total cholesterol (TC), LDL-C, IgE, CRP and IL-6 (P<0.001) and lower 25 (OH) vitamin D levels (P<0.001) compared to controls. Within the PCOS group, 47 patients developed asthma with a significant increase in BMI (P=0.003), CRP and IgE levels (P<0.001) compared to non-asthmatic PCOS. Both asthmatic PCOS and asthmatics expressed elevated BMI, IgE, IL-6 and CRP levels, but with no significant difference between them. Asthmatic PCOS showed significantly higher testosterone and dyslipidemia profile. Multivariate regression revealed that BMI and CRP could predict asthma development within PCOS (OR=1.104, C.I 1.004–1.2 and OR=1, C.I. 1–1.02), respectively. Receiver operating characteristic (ROC) curve showed that BMI and CRP at a cutoff value 28.5 kg/m2and 117.6 nmol/L respectively could differentiate between asthmatic and non-asthmatic PCOS with sensitivity 63.8 % and specificity 62% for BMI, and sensitivity and specificity of 66% for CRP.

Conclusions

This study shows that BMI and CRP are predictors of asthma development in Egyptian PCOS.
