Authors: Paris Angelo , Beccati Francesca , Pepe Marco 
Published: May 2021

Abstract

OBJECTIVE
To report the type, prevalence, and risk factors for the development of orthopedic injuries in endurance horses.

ANIMALS
235 endurance horses.

PROCEDURES
Medical records of horses examined between January 2007 and December 2018 were reviewed. Recorded data were birth; breed; sex; dates of first and last examinations; presence of any conformation fault, lameness, positive flexion test result, and orthopedic injury; starts in endurance competitions; level of athletic activity; professional status of trainer or rider; and whether an orthopedic injury developed in > 1 limb or during or within 2 days after competition, lameness resolved after treatment, reinjury occurred, horse was eliminated from competition after treatment, and the horse required retirement from endurance competitions. Anatomic locations of injuries were classified as proximal portion of the metacarpal area, midportion of the metacarpal area, metacarpo- or metatarsophalangeal (fetlock) area, tarsus, or foot. For each outcome, multivariable logistic regression models were developed after bivariable logistic regression and collinearity analyses.

RESULTS
351 orthopedic injuries were detected in 76.6% of the horses, with 27.1% that affected the fetlock area, 21.4% the proximal portion of the metacarpal area, 21.1% the foot, 12.8% the tarsus, 9.1% the midportion of the metacarpal area, and 8.5% other sites. High suspensory disease (21.4%) was the most common condition, followed by arthropathy of the metacarpo- or metatarsophalangeal joint (19.4%) and solar pain (14%). Age at first examination (OR, 1.70; 95% CI, 1.37 to 2.11), months of observation (OR, 1.03; 95% CI, 1.01 to 1.05), conformation fault of forelimbs (OR, 4.08; 95% CI, 1.53 to 10.89), and amateur status (OR, 2.62; 95% CI, 1.86 to 7.99) remained significant in the final multivariable regression model for the development of orthopedic injuries.

CONCLUSIONS AND CLINICAL RELEVANCE
A large number of endurance horses developed ≥ 1 orthopedic injury during training or competition. Clinical and diagnostic examinations should be focused with particular attention to the metacarpophalangeal joints, proximal portion of the metacarpal area, and foot.

Published: May 2021

Abstract

OBJECTIVE
To compare immune responses induced by 2 commercially available vaccines with a bovine herpesvirus type 1 (BHV1) component following intranasal (IN) administration to colostrum-fed calves.

ANIMALS
90 male Holstein calves (ages, 5 to 14 days).

PROCEDURES
In a randomized complete block design, each calf received 2 mL (1 mL/nostril) of vaccine A (n = 30), vaccine B (30), or saline (0.9% NaCl) solution (30) on day 0. Blood samples were collected for determination of serum anti-BHV1 IgG titer, and nasal fluid (NF) samples were collected for determination of interferon (IFN)-α and IFN-γ concentrations and for secretory IgA titers against BHV1, Mannheimia haemolytica, and Pasteurella multocida at predetermined times for 42 days after vaccination.

RESULTS
All calves were seropositive for anti-BHV1 IgG, and the mean anti-BHV1 IgG titer did not differ significantly among the 3 groups at any time. Both vaccines induced significant transient increases in NF IFN-α and IFN-γ concentrations. On day 5, mean IFN-α concentration and the proportion of calves with detectable IFN-α concentrations for the vaccine A group were significantly greater than those for the vaccine B and control groups. On day 42, the mean NF anti–P multocida IgA titers for both vaccine groups were significantly greater than that of the control group.

CONCLUSIONS AND CLINICAL RELEVANCE
Both vaccines induced innate and acquired immune responses in calves with colostral antibodies. The magnitude of the IFN-α response and proportion of calves with detectable IFN-α differed between the 2 vaccine groups. Both vaccines appeared to enhance the IgA response against P multocida.
Successful and unsuccessful nonsurgical removal of ingested golf balls and an artificial egg in four rat snakes (Pantherophis alleghaniensis)
Authors: Scott Gregory , Waffa Bradley J. , DeVoe Ryan S. , Harms Craig A. , Lewbart Gregory A. 
Published: May 2021

Abstract

CASE DESCRIPTION
4 wild adult rat snakes (Pantherophis alleghaniensis) were evaluated after ingesting spherical or ovoid foreign bodies.

CLINICAL FINDINGS
Physical examination revealed a large, firm mass at the level of the stomach in each snake. Radiographic findings were consistent with ingestion of a golf ball (3 snakes) or an artificial egg (1 snake). Signs consistent with prolonged impaction included scale loss, dermal abrasions, and apparent loss of body condition in one snake and regional skin ulceration, dehydration, and generalized muscle atrophy in another.

TREATMENT AND OUTCOME
Nonsurgical removal of the foreign body was attempted in anesthetized or heavily sedated snakes by external manipulation in the orad direction. A golf ball was removed through the oral cavity without complications in 1 snake. In the other 3 snakes, tension caused by the advancing foreign body resulted in full-thickness skin rupture in the cervical region. The procedure was completed with the use of a balloon catheter to aid foreign body advancement for 1 of the 3 snakes, and the skin defect was closed. The procedure was converted to esophagotomy for the other 2 snakes. Three snakes recovered and were released; 1 died of complications from prolonged impaction and esophageal perforation.

CLINICAL RELEVANCE
The described nonsurgical techniques for removal of ingested round or ovoid foreign bodies were associated with substantial complications in 3 of 4 treated rat snakes. Although a nonsurgical method for removal of ingested objects such as golf balls could benefit snakes, the methods used for these patients did not appear to be more beneficial than traditional gastrotomy.
Thermodynamic prediction of proton and hydrogen atom abstraction in dehydroascorbic acid and its bicyclic form
Authors: Štellerová Dagmar , Lukeš Vladimír 
Published: May 2021

Abstract
Conformation analysis of dehydroascorbic acid and its bicyclic form was performed using the density functional theory. For the energetically preferred conformations, ionization potentials (IP) and bond dissociation enthalpies (BDE) were calculated using the B3LYP functional and 6-311++G** basis set. The effects of aqueous solution were estimated using the solvation model based on density (SMD) and the polarizable continuum model (IEF-PCM). The obtained results were compared with available experimental data for reference L-ascorbic acid (vitamin C). Our calculations indicate that the investigated bicyclic metabolic product of vitamin C can also exhibit limited radical scavenging ability due to the thermodynamically preferred dissociation of tertiary —CH bonds.
Attribute Reduction Method Based on Sample Extraction and Priority
Authors: Wang Biqing 
Published: May 2021

Abstract
Attribute reduction is a key issue in the research of rough sets. Aiming at the shortcoming of attribute reduction algorithm based on discernibility matrix, an attribute reduction method based on sample extraction and priority is presented. Firstly, equivalence classes are divided using quick sort for computing compressed decision table. Secondly, important samples are extracted from compressed decision table using iterative self-organizing data analysis technique algorithm(ISODATA). Finally, attribute reduction of sample decision table is conducted based on the concept of priority. Experimental results show that the attribute reduction method based on sample extraction and priority can significantly reduce the overall execution time and improve the reduction efficiency.
Development of student simulated patient training and evaluation indicators in a high-fidelity nursing simulation: a Delphi consensus study†
Authors: Yuan Hao-Bin 
Published: May 2021

Abstract

Objective
This study is aimed to develop student simulated patient (SSP) training content and evaluation indicators, and further explores their validity and reliabilities.

Methods
Delphi consultations with 20 nursing experts were conducted. The weights of indicators were calculated through the analytic hierarchy process. SSP training was conducted with a high-fidelity nursing simulation.

Results
The expert positive coefficients were 0.952 in the first round consultation and 1.00 in the second round consultation. The expert authority coefficient was reported as 0.87. The training included role and responsibility of simulated patient (SP), script interpretation, plot performance, and training for a rater, with a total of 17 indicators. SSP evaluation consisted of disease knowledge, role portrayal, and performance fidelity and since being a rater, it consists of 20 indicators in total. The coordination coefficients of two rounds of consultation ranged from 0.530 to 0.918. The content validity of SSP evaluation indicators was 0.95. The inter-rater reliability was reported as 0.866, and the internal consistency established using Cronbach’s α was 0.727.

Conclusions
Students as SPs should have first-hand knowledge and experience within the simulated scenarios. SSP training content and evaluation indicators were determined through the Delphi consensus combined with analytic hierarchy process. The evaluation indicators were valid and reliable, and provided the objective and quantifiable measurements for SSP training in nursing.
How sport and its values are perceived by adults in the USA and Ukraine: a cross-cultural comparison
Authors: Turchyk Iryna , Romanchuk Olha , Sorokolit Natalija , Kemin Volodymyr , Lukjanchenko Mykola 
Published: May 2021

Abstract
There are practically no cross-cultural studies in the field of physical education and sport with Ukrainian society as the object of research. However, there is a particular and obvious interest to research not only young people as a major strategic resource for any state, but also adults, including parents. The main purpose of the study is to identify common and different features of the attitude toward sport and its axiological component in the Ukrainian and American societies. A total of 500 adults aged 18-64 (196 men and 304 women) participated in the national survey, with the majority being Ukrainian school teachers. The results obtained from the study were compared with the results of a study conducted in the United States. It should be noted that in our study, we only selected questions from the American questionnaire that solely addressed adults’ perceptions of sport and its values. We did not choose other questions. Mathematical processing of the survey indicators was carried out using the computer program SPSS. The result of the research is a comparison of statements from adults of both countries regarding the actual and potential impact of social institutions on the youth; their statements about sport; values or principles that may or may not be important in sport; the extent of sport’s actual influence on the formation of values; the values adults hope their children will learn from participating in sport; and statements about the importance of values from adults who are actively involved in sport. The results of the cross-cultural study among adults in the USA and Ukraine indicate that there is both an identical idea of certain values in sport and a different vision due to, in our opinion, the divergence of cultural traditions and the status of sport in the countries.
Cerebral Gas Embolism in the Course of Mildly Symptomatic Pulmonary Barotrauma in a Scuba Diver
Authors: Kierznikowicz Brunon , Teresiński Stefan 
Published: May 2021

Abstract
The paper presents a case of pulmonary barotrauma in a scuba diver. Swallowing water and respiratory arrest during the ascent caused the trauma. Symptoms from the respiratory system (including the Behnke’s symptom) appeared several minutes after the completion of the dive and were not severe. However, symptoms from the peripheral nervous system, which appeared later, increased rapidly until the seizure episode and loss of consciousness. Hyperbaric treatment was applied in a decompression chamber on board the ship from which the dive was conducted. The treatment resulted in complete remission of symptoms without any consequences.
Diver Poisoning with Contaminated Compresses Air
Authors: Olszański Romuald , Mamet-Ossowska Elżbieta 
Published: May 2021

Abstract
The paper describes the case of a military diver who suffered from a complicated poisoning caused by hydrocarbons contained in his breathing air. The hydrocarbons came from a malfunctioning compressor which was used to fill the diving cylinders; the compressor sucked in the exhaust gases of its own motor. Exhaust gas poisoning was further complicated by hypoxia and hypercapnia as the diver spat out the mouthpiece and started to breathe from inside the suit. This resulted in a loss of consciousness. The diver was extracted to the surface and was given oxygen to breathe. The course of treatment was successful. On the same day, symptoms of exhaust gas poisoning occurred in several divers using cylinders filled with the same compressor.
Heave Motion of a Vertical Cylinder with Heave Plates
Authors: Ciba Ewelina 
Published: May 2021

Abstract
The shape of a vertical cylinder resembles the classic form of a spar platform. Spar platforms are floating platforms that are successfully used in waters of great depths and have several advantages that mean they are readily used in the oil industry. Many of these advantages are also relevant to their application for offshore wind turbines, which is currently being considered. In the hydrodynamic analysis of spar platforms, the determination of their hydrodynamic coefficients plays an important role. They can be determined based on the free decay test. The study presents a method for determining the hydrodynamic coefficients of an object based on the free decay test. The results of free oscillation calculations with the help of numerical fluid mechanics tools are presented and compared with the results of the experiment and analytical solution. The application of determined coefficients and their significance for floating platforms are discussed. The influence of change in the form of an additional damping element on the behaviour of spar structures is shown.
Medical and psychosocial evaluation of patients with complications after sinonasal surgery: Creating a questionnaire
Authors: Vidinei Manuela-Andra , Sarafoleanu Codrut 
Published: May 2021

Abstract

BACKGROUND. In our ENT practice, we have encountered situations where we had to evaluate and treat patients complaining of symptoms after a previous surgery. All these patients were capable and entitled to seek for legal advice as much as medical care. We felt the need to record their physical and emotional status and to monitor their evolution in these fields. For this reason, we created a questionnaire to help us not to disregard some important or delicate aspects of their condition.

MATERIAL AND METHODS. After evaluating all the existing ENT questionnaires, we decided to create a custom one in order to assess more of the sensitive topics as anger, sadness, regret or frustration. Questions needed to be asked in a certain manner and must be presented in a well-thought order, respecting some basic rules. The evaluation scale needed to be very clear, simple to complete and compare, and identical for all the questions.

RESULTS. Creating a questionnaire was a challenging task that led us to an 18-question survey, equally covering symptoms, feelings and quality of life. We used the test only for the patients who presented after a sinonasal surgery and who suggested that their symptoms were caused by the previous intervention.

CONCLUSION. A questionnaire is a simple and cheap way to evaluate patients. If the topics needed to be documented are not stated in a classic validated survey, a new evaluation instrument can be created. For patients with complications and sequelae after sinonasal interventions, we designed a new questionnaire that can be used to compare their treatment progression.

Authors: Dakhil Husam Talib , Alwan Muhanned Moussa , Mohammed Nassr Abdulsalam 
Published: May 2021

Abstract

OBJECTIVE. To evaluate the effects of steroid-impregnated middle meatal packing on post-operative outcome after endoscopic sinus surgery.

MATERIAL AND METHODS. We performed a prospective clinical study on 26 randomly selected patients, older than 12 years, with chronic rhinosinusitis, who failed medical management and who were operated on by endoscopic sinus surgery at Al-Imamain Al-Kadhimyain Teaching Medical City over a period of 12 months. Patients were divided into two groups: the 1st with middle meatal packing soaked with steroids (triamcinolone) and the 2nd group with middle meatal packing alone, without steroid. The two study groups were followed-up postoperatively for adhesions, crustations and nasal discharge over a period of three months.

RESULTS. The study showed a significant reduction in early nasal crustations (p-value=0.048) and nasal discharge (p-value=0.033) after endoscopic sinus surgery in patients who received triamcinolone-impregnated middle meatal packing. Synechia formation was significantly lower in the steroid-impregnated group one month after surgery (p-value=0.021), but no difference at one week (p-value=0.089). At the three-month follow-up, comparing the two groups, the following variables were not statistically significant: crusts (p-value=0.22), nasal discharge (p-value=0.26), synechia (p-value=0.074).

CONCLUSION. There are significant reductions in the incidence of early crustations, synechia, nasal discharge in patients who received triamcinolone middle meatal packing following endoscopic sinus surgery.
Age of maturity and exceptionally distant natal dispersal of over 500 km by a male lesser spotted eagle Clanga pomarina
Authors: Meyburg Bernd-Ulrich , Matthes Hinrich , Maciorowski Grzegorz 
Published: May 2021

Abstract
According to previous studies using colour rings, lesser spotted eagles Clanga pomarina have established breeding territories up to 249 km from their natal site. A colour-ringed lesser spotted eagle nestling from NE Poland settled 540 km further west in NE Germany. This male was discovered at the age of six and nested there for several years. This finding is all the more remarkable because the bird was a male, which in large eagles typically settle nearer to their natal sites than females. They apparently reproduce successfully for the first time later than females, normally at the age of five.
Summary of raptor and owl ringing in Slovakia in the period from 2012 to 2019
Authors: Slobodník Roman , Jenčo Michal 
Published: May 2021

Abstract
Between 2012 and 2019, 6523 raptors and owls (30 species) were ringed in Slovakia. The most abundant was the common kestrel (2811 individuals), then the western marsh harrier (664) and saker falcon (517). The proportion of nestlings among all the ringed individuals was 84.4%. In the given period, 340 recoveries of raptors and owls (23 species) were recorded in the ringing station database. This number included 160 recoveries of individuals colour-marked and also recovered in our territory. There were 83 recoveries of birds ringed in Slovakia and resighted abroad. The last 97 recoveries were of individuals ringed abroad and recovered in Slovakia. In summary, most of the recoveries (of all types) were of Eastern imperial eagle (62 recoveries), then red-footed falcon (51) and common kestrel (43). Most of the recovery circumstances were ring reading (44% in total), recaptures (15%) and findings of bird cadavers. Regarding raptors or owls, collisions with vehicles (5%) and electrocutions (5%) were frequent causes of their deaths.
