The purpose of the study to assess the results and risk of complications of primary total knee arthroplasty in patients with a history of osteosynthesis of intra-articular fractures. Materials and Methods. Our study integrates the retrospective and prospective analysis of the results of primary total knee arthroplasty (TKA) performed in 140 patients, in period from 2015 to 2019. The retrospective part of the study included the arthroplasty results of 100 patients, prospective 40 patients. Each of the groups was divided into 2 subgroups: with previous osteosynthesis (MOS) of intra-articular fractures before arthroplasty and without history of knee surgery before arthroplasty. To assess the results of TKA, adapted to Russian-language versions of the KSS, WOMAC and FJS-12 scales were used. The X-ray of the endoprosthesis components positioning was assessed using the KRESS scale. Results. Statistically significant differences were found between retrospective groups with MOS and without it in the duration of the surgery, in the volume of intraoperative blood loss, in the higher frequency for implantation of the endoprosthesis systems with an increased degree of coupling of the components. The rate of postoperative complications was higher in retrospective group MOS. Mid-term functional results did not show statistically significant differences on the KSS and WOMAC scales, patient satisfaction rates on the FJS-12 scale were worse in retrospective group MOS. Prospective group of patients with a history of MOS for intraarticular fractures demonstrated statistically significant increase of the knee ROM from 89 to 108, after the TKA. The function recovery dynamics according to the KSS, WOMAC and FJS-12 was slowed down at 3 and 6 months, and according to the WOMAC and FJS-12 scales, even after 12 months post-operation. Conclusion. The previous trauma and knee intra-articular fractures fixation leads to an earlier development of post-traumatic osteoarthritis. Functional results in the retrospective and prospective groups do not have statistically significant differences. The number of postoperative complications is greater in the retrospective groups. MOS in the history statistically significantly slows down the dynamics of function recovery in the early postoperative period.

Published: December 2021

Background

Intimate partner and sexual violence are pervasive public health issues on college and university campuses in the United States. Research is recommended for creating and maintaining effective, relevant, and acceptable prevention programs and response services for student survivors.

Objective

The University of California (UC) Speaks Up study aims to examine factors contributing to intimate partner and sexual violence on 3 UC campuses and use the findings to develop and test interventions and policies to prevent violence, promote health, and lay the groundwork for subsequent large-scale quantitative research.

Methods

A mixed methods study was conducted at UC Los Angeles, UC San Diego, and UC Santa Barbara. Phase I (2017-2020) involved a resource audit; cultural consensus modeling of students’ perceptions of sexual consent; in-depth interviews (IDIs) and focus group discussions with students to understand perceptions of campus environment related to experiences as well as prevention of and responses to violence; and IDIs with faculty, staff, and community stakeholders to investigate institutional and community arrangements influencing students’ lives and experiences. Phase II (2020-ongoing) involves IDIs with student survivors to assess the use and perceptions of campus and community services. Qualitative content analysis is used to generate substantive codes and subthemes that emerge, using a thematic analysis approach.

Results

In January 2019, we conducted 149 free-listing interviews and 214 web-based surveys with undergraduate and graduate and professional students for the cultural consensus modeling. Between February 2019 and June 2019, 179 IDIs were conducted with 86 (48%) undergraduate students, 21 (11.7%) graduate and professional students, 34 (19%) staff members, 27 (15.1%) faculty members, and 11 (6.1%) community stakeholders, and 35 focus group discussions (27/35, 77% with undergraduate students and 8/35, 23% with graduate and professional students) were conducted with 201 participants. Since September 2020, 50% (15/30) of the planned student survivor interviews have been conducted. This segment of data collection was disrupted by the COVID-19 pandemic. Recruitment is ongoing.

Conclusions

Data analysis and phase II data collection are ongoing. The findings will be used to develop and test interventions for preventing violence, promoting health and well-being, and ensuring that survivor services are relevant and acceptable to and meet the needs of all individuals in the campus community, including those who are typically understudied. The findings will also be used to prepare for rigorous, UC–system-wide public health prevention research.

Published: December 2021

The Kidney Precision Medicine Project (KPMP) seeks to establish a molecular atlas of the kidney in health and disease and improve our understanding of the molecular drivers of CKD and AKI. Herein, we describe the case of a 66-year-old woman with CKD who underwent a protocol KPMP kidney biopsy. Her clinical history included well-controlled diabetes mellitus, hypertension, and proteinuria. The patient’s histopathology was consistent with modest hypertension-related kidney injury, without overt diabetic kidney disease. Transcriptomic signatures of the glomerulus, interstitium, and tubular subsegments were obtained from laser microdissected tissue. The molecular signatures that were uncovered revealed evidence of early diabetic kidney disease adaptation and ongoing active tubular injury with enriched pathways related to mesangial cell hypertrophy, glycosaminoglycan biosynthesis, and apoptosis. Molecular evidence of diabetic kidney disease was found across the nephron. Novel molecular assays can supplement and enrich the histopathologic diagnosis obtained from a kidney biopsy.

Using thermochemical code EXPLO5 to predict the performance parameters of explosives
Authors: Suceska Muhamed , Stimac Tumara Barbara , Künzel Martin
Published: December 2021

Thanks to the development of more powerful computers and efficient numerical techniques, numerical modelling has become a compulsory tool in solving various problems in the field of energetic materials. In cases where measuring techniques are still unable to measure a given parameter, numerical modelling may be the only option of obtaining a value. In addition, numerical modelling helps us to better understand some phenomena, particularly in understanding the influence of input parameters on output results, as well as saving time and money. The thermochemical equilibrium code EXPLO5 is such a tool which enables theoretical prediction of performance of high explosives, propellants and pyrotechnic compositions. The code is used by more than 80 research laboratories worldwide.
Scaled-down test arrangements for characterizing high explosives
Authors: Künzel Martin , Kučera Jindrich
Published: December 2021

Newly formulated explosives and the optimization of explosive mixtures requires an experimental determination of detonation parameters, especially detonation velocity, pressure and metal accelerating ability. Increasing material and labour costs force researchers to reduce test quantities and therefore to develop smaller scale experiments which provide sufficient data to determine an explosive’s properties. Seven test set-ups found in literature are described and compared in this paper.

Authors: Ubaydullaevich Mamasoliev Ikrom
Published: December 2021

Annotation: The article analyzes the problems of formation of syntactic connections in applied constructions in modern fiction. The author tried to justify the need to separate the applied phenomenon as a separate type of syntactic connection with specific structural and semantic features. Applied phenomenon is expressed by a stylistic style that allows one or another piece of information in a sentence to be activated and is a type of syntactic connection in the modern syntactic system of the German language that requires more consistent and systematic study and description. Keywords: syntactic connection, applied phenomenon, applied construction, complex sentence, compound sentence.

The present study aimed to evaluate, in vitro, the cestocidal effect of Pyrantel-Oxantel on the Dipylidium caninum tapeworm. Each intestine sample was obtained by means of a transversal incision of the abdominal area of each euthanized canine subject, individually dissected via  longitudinal incision, and examined for the presence of D. caninum. An optical microscope was used to identify and verify proglottid morphology and viability based on its macroscopic appearance. The cestocidal effects of Pyrantel-Oxantel (75 mg pyrantel pamoate; 75 mg oxantel pamoate) were assessed in adult tapeworms (treated group, n= 21; control group, n= 21) placed on Petri dishes and incubated at 37 °C. One-hour post-incubation, the D. caninum cestodes treated with Pyrantel-Oxantel presented a 28 % decrease (P=0.001) in motility, which rose to a 52 % (P=0.0001) decrease by the end of the second hour. The control group (P=0.0001) presented 55.7 % motility for at least the first six hours of incubation and 4.2 % (P=0.001) motility by the end of the study, while 0 % motility was observed in the treated group by the end of the study. Pyrantel-Oxantel had a lethal effect (P=0.0001) on adult D. caninum, with 100 % mortality observed 6 h after in vitro post-incubation, while the control group presented 55.7 % viability after the same time period. In addition, Pyrantel-Oxantel reduced (P=0.001) tegument thickness by 42.5 % (10.24 ± 0.21 µm), while this was 17.81 ± 0.33 µm for the control group. The results of this study indicate that Pyrantel-Oxantel has a therapeutic effect on the presence of D. caninum, inducing both a reduction of the tegument thickness and increased mortality.

Las temperaturas elevadas registradas durante la época de verano en las regiones cálidas comprometen la capacidad reproductiva de los animales domésticos. En carneros, el estrés por calor (EC) causa en el organismo una serie de ajustes fisiológicos, metabólicos, endocrinos y moleculares con el objeto de mantener normotermia y sobrevivir; sin embargo, varios de estos cambios se asocian negativamente con su fertilidad, principalmente los endocrinos. El EC en carneros provoca una disminución en las concentraciones sanguíneas de testosterona a través de diferentes mecanismos, y esto se refleja negativamente en el proceso de espermatogénesis y en la conducta sexual. En consecuencia, los carneros estresados por calor presentan baja calidad seminal y apetito sexual; a nivel de espermatozoides se ha observado daño estructural y en el ADN. Dada esta situación, se recomienda el uso de estrategias de mitigación del EC durante el verano en las explotaciones ovinas de regiones cálidas, tales como el uso de sombras en corrales, la administración de antioxidantes o modificaciones en la alimentación. Por lo tanto, el objetivo de este documento es revisar el conocimiento actual en relación al efecto del EC sobre la capacidad de termorregulación y reproductiva de los carneros, así como la aplicación de estrategias para su mitigación.

Published: December 2021

Objective: To identify preferred solutions – therapy - for over- weight and obesity in older adults and seniors Participants: Atotal of 110 respondents were contacted, out of which 14 refused to cooperate or filled in the questionnaire incor- rectly. The return of questionnaires was 96, i.e. 100%. The group of respondents consisted of individuals of both sexes, aged 50 and over, living in anatural social environment or in one of the se- lected institutions. Due to the fact that - in our opinion - arela- tively large amount of attention is paid to the senior age group while the group of people in the age range of 50-64 is forgotten, we have not chosen the senior age respondents exclusively. Methods: The data obtained by the processing of the question- naires were analytically evaluated. For statistical processing apro- gram StatisticaCz version 9 was chosen, adescriptive analysis of the data was performed, followed by analysis by comparing av- erages and particular tests of statistical significance (Chi-square test, Kruskal Wallis, KendalovoTau). Results: An adjustment of the diet as apart of the solution of the overweight and obesity therapy would be chosen by the most re- spondents, 75 (46.5%) of them. 44 (27.0%) respondents would choose sport or other physical activity. 11 (6.7%) respondents would deal with overweight and obesity pharmacologically - with the help of medications, and only 25 (15.3%) respondents would choose surgery as away of dealing with overweight and obesity. On the contrary, only 8 (4.9%) respondents were not interested in dealing with the weight gain. 24 (25.0%) respondents would choose the surgical way of solving obesity. Ananswer“possibly yes”was chosen by13 (13.5%) respondents. 21 (21.9%) individu- als inclined to the “rather not” variant. 33 (34.4%) respondents chose the “certainly not”answer. An answer“I don't know” was chosen by 5 (5.2%) respondents. Conclusion:Obesity is aglobal social problem which is not to be solved just in healthcare and it is certainly not an issue of an individual.

Authors: Velame Ferreira Teixeira Barbara , Da Cruz Tiala Barbosa Ferreira
Published: December 2021

Uma prescrição deve conter os dados necessários para o uso correto dos medicamentos. Erros provenientes da prescrição inadequada podem resultar em sérios danos à saúde dos pacientes. Nesse contexto a ANVISA – Agência Nacional de Vigilância Sanitária publicou a RDC nº 20/2011 a fim de normatizar a prescrição e dispensação dos antimicrobianos, pois esta é uma classe que o uso excessivo e irracional causa graves danos à saúde dos usuários. O objetivo desta pesquisa foi analisar as prescrições de antimicrobianos dispensados em uma farmácia comunitária localizada no Recôncavo da Bahia. Analisou-se as prescrições dispensadas no período de janeiro de 2018 a janeiro de 2019. Os dados foram tabulados em planilhas onde foram avaliados a presença dos elementos obrigatórios em uma prescrição de antimicrobiano. Para análise das interações medicamentosas foi utilizada a base de dados Micromedex® (MDX). Avaliou-se 704 prescrições, a classe mais prescrita foi a dos beta-lactâmicos (36,86%). De acordo as exigências legais nenhuma prescrição possuía todos os dados considerados obrigatórios em uma prescrição. Desta forma, é necessário elaborar mais estudos, campanhas de conscientização para pacientes e prescritores, e ter um maior controle tanto na prescrição como na dispensação destes medicamentos.
The effect of financial literacy on behavioral biases of individual investors in the Egyptian stock exchange
Authors: Youssef Amr , Tantawi Passent , Ragheb Mohamed , Saeed Mohammad
Published: December 2021

The purpose of this paper is to examine how the dimensions of financial literacy could affect the behavioral biases of individual investors in the Egyptian stock exchange. The study examines the data collected from 403 individual investors in Egypt. The findings revealed the presence of some kinds of behavioral biases among individual investors in the Egyptian stock exchange, which could be categorized into three main categories: belief perseverance biases, information processing biases, and emotional biases (Pompian, 2012). This supports the view that individual investors do not necessarily act rationally. The findings also support the general view that financial literacy has a negative effect on behavioral biases; however, the effect differs between the categories of the behavioral biases, with the most effect on information processing biases, moderate effect on belief perseverance biases, and low effect on emotional biases. Also, this study indicated that the impact of financial literacy on behavioral biases is greater on females than males (Baker, Kumar, Goyal, & Gaur, 2019). Financial intermediaries and consultants can possibly become more effective by understanding the decision-making processes of individual investors. This study adds to the limited academic research that attempted to tackle the impact of financial literacy on the categories of behavioral biases

The aim of the present paper is to study the mechanical properties of
aluminate cement mortar mixed with different chopped fibers under high
temperature. The specimens with a size of 40 mm ? 40 mm ? 160 mm is treated
at various tempera?tures of 25?C, 200?C, 400?C, 600?C, and 800?C. The
compressive and flexural strength of the aluminate cement mortar and its
micro-structures are tested. The results show that the chopped steel fibers
and basalt fibers are effective in improv?ing the high temperature
mechanical properties of aluminate cement mortar. When the volume fraction
of chopped steel fibers is 2%, the compressive strength and flexural
strength of the test block treated at the temperature of 800?C increase by
18.3% and 128.6%, respectively.

Published: December 2021

Uncertainties in the basic theory of shallow mining that continues to be used
in deep mining result in frequent engineering disasters with deep
characteristics. Thus, it is necessary to elucidate the mechanism of
mechanical deformation and failure behavior of coal from shallow to deep
depths. Coal samples from the same coal seam in the Pingdingshan mining area
of Henan Province were obtained at depths of 300 m, 600 m, 700 m, 850 m, and
1050 m. Direct tensile tests were conducted on the coal samples obtained at
different depths. The tensile strength exhibits as low decreasing trend with
increasing depth, reaching a minimum at 1050 m. This variation trend is
consistent with that of acoustic emission cumulative ring-down counts and
the cumulative energy measured during tensile tests on coal samples obtained
at different depths. These conclusions provide a reference for the
differences between the mechanical behavior of shallow and deep coal, which
has both theoretical and engineering significance.

A new RLC series-resonant circuit modeled by local fractional derivative
Authors: Dong Mei , Li Cui-Ling , Chen Wu-Fa , Li Guo-Qian , Wang Kang-Jia
Published: December 2021

The local fractional derivative has gained more and more attention in the
field of fractal electrical circuits. In this paper, we propose a new
?-order RLC** resonant circuit described by the local fractional derivative
for the first time. By studying the non-differentiable lumped elements, the
non-differentiable equivalent imped?ance is obtained with the help of the
local fractional Laplace transform. Then the non-differentiable resonant
angular frequency is studied and the non-differentiable resonant
characteristic is analyzed with different input signals and parameters,
where it is observed that the ?-order RLC resonant circuit becomes the
ordinary one for the special case when the fractional order ? = 1. The
obtained results show that the local fractional derivative is a powerful
tool in the description of fractal circuit systems.

A simple method to calibrate the temperature effect for the calculation of gas permeability
Authors: Ma Shi-Jia , Lin Yuan-Jian , Liu Jiang-Feng , Chen Tao , Wang Pei-Lin , Zhang Fan
Published: December 2021

Temperature plays an important role in the gas permeability test. A small
temperature variation still exists in the experimental process since the
temperature control device cannot strictly maintain a constant temperature.
This can further affect the accuracy of the gas permeability. To solve this
problem, a simple method based on the ideal gas equation of state is
introduced to calibrate the gas pressure variation because of the
temperature effect. We verified the calibration results through sever?al
examples, and the results proved the feasibility and effectiveness of the
method. In particular, this method is particularly effective for low
permeability materials in long-term gas permeation tests.
Effects of Local Anesthetics With Vasoconstrictors on Dental Pulp Blood Flow and Oxygen Tension
Authors: Tachibana Keikoku , Kasahara Masataka , Matsuura Nobuyuki , Ichinohe Tatsuya
Published: December 2021

Objective:

The aim of this study was to investigate the changes in pulpal blood flow (PBF) and pulpal oxygen tension (PpulpO2) after injecting local anesthetics with vasoconstrictors.

Methods:

Under general anesthesia, male Japanese White rabbits were injected with 0.6 mL of 2% lidocaine with 1:80,000 epinephrine (LE) or 3% propitocaine (prilocaine) with 0.03 IU felypressin (PF) at the apical area of the lower incisor.

Results:

Relative to baseline, PBF and PpulpO2 significantly decreased 5 minutes after LE or PF injection as compared with saline. The decrease in PBF was significantly lower in the LE group than in the PF group. Although the LE group had a larger decrease in PpulpO2 relative to baseline than the PF group did, that difference was not significant. PBF and PpulpO2 recovered to baseline faster in the PF group than in the LE group.

Conclusion:

The injection of local anesthetic solutions containing vasoconstrictors (LE or PF) transiently caused significant decreases in PBF that resulted in significant decreases in PpulpO2. The recovery of PpulpO2 was faster than PBF regardless of the vasoconstrictor used.
A Case of Nasal Mucosa Cautery With Reintubation Under Pharyngeal Suction for Massive Epistaxis After Extubation
Authors: Arai Yukiko , Hasegawa Akari , Kameda Aki , Mitani Saki , Uchida Takuya , Kato Yasuhiko , Manabe Yozo , Momota Yoshihiro
Published: December 2021

We describe a case of massive epistaxis that occurred after removal of a nasal endotracheal tube, prompting emergent reintubation. Mask ventilation could not be performed because the nasal cavity was packed with gauze and the airway was being evacuated with a suction catheter. Therefore, instead of inhalational anesthetics and muscle relaxants, boluses of midazolam and remifentanil were administered, and reintubation was promptly performed. Sedation was maintained with dexmedetomidine infusion and midazolam. Nasal cautery was performed near the left sphenopalatine foramen. The patient was extubated without agitation or additional hemorrhage. Immediate recognition of the potential for airway loss, sufficient control of active bleeding, and drug selection in accordance with the emergent circumstances enabled prompt resecuring of the airway without pulmonary aspiration of blood.
Efficient distortion predictions of high-performance steel alloy parts fabricated by pragmatic deposition strategies in laser melting deposition
Authors: Duan Chenghong , Cao Xiankun , Luo Xiangpeng
Published: December 2021

For the prediction of residual distortions of high-performance steel alloy parts induced by laser melting deposition (LMD), two efficient simulation methods are developed, which are the improved thermal-mechanical coupled method and the multiscale method. In the improved thermal-mechanical coupled method, the detailed loading process of the moving laser heat source is omitted, and the deposited coarse blocks are used to divide the LMD parts, which can improve the efficiency of mechanism exploration for the LMD process. Based on the eight-layer line deposition model, the length range of the deposited coarse blocks that can improve the computational efficiency under the premise of accuracy is explored, which is 5–8 mm. The distortion of the substrate after printing two-layer multipath part by pragmatic deposition strategies is accurately predicted by this method, which is consistent with the experimental measurement. The deviation between the predicted maximum distortion and the actual value is only 0.8%. Furthermore, a multiscale method based on the inherent strain method is also adopted. The two simulation methods are used to predict the distortion of the substrate after depositing pragmatic square frame structure. The deviations of the maximum distortion predicted by the improved thermal-mechanical coupled method and the multiscale method are 5.2% and 4.3%, respectively. The time-consuming of the multiscale method is only 2.8% of the former. For the direct prediction of distortion results of large-sized LMD parts in engineering, the advantages of the multiscale method are significant.

A collaborative optimization strategy is proposed through an in-depth analysis and research on the coordination information of cross-border e-commerce in the Belt and Road Initiative (BRI). In terms of research ideas, the logistics network model of cross-border e-commerce overseas warehouse mode under maritime and air transport modes is established to reach the optimization objectives of cost-saving, time efficiency, and best satisfaction, and to realize the optimal resource allocation and the best combination of elements; in terms of technical route, the diversity of the solution set is maintained or even improved through a more advanced diversity maintenance strategy, which improves the convergence of the solution set while maintaining or even improving the diversity of the solution set, thus improving the overall performance of the solution set. In terms of method application, the overseas warehouse model of international coordination network for cross-border e-commerce under two models of coordination cost-sensitive ocean freight mode and time-cost-sensitive air freight mode are analysed by examples respectively to verify the effectiveness of the model and algorithm.

Nowadays bacteriophages are widely used in veterinary medicine, bio-technology, agriculture and in particular in aquaculture. Narrow specificity affecting the bacterial microflora and selective influence on the pathogenic and opportunistic microorganisms allow using the bacteriophages for diagnosing, preventing and treating the diseases of farm animals and fish. The emergence of antibiotic-resistant strains of microorganisms involves the search for new drugs to combat them. In this regard, phage therapy is an alternative to antimicrobial treatment of bacterial diseases of animals and fish. Despite the lack of data on the bacteriophage-based drugs applications in aquaculture, this direction is found to be promising and relevant. There is given a comparative analysis of the microbiocenosis of the gills and intestines of two-year-olds of red tilapia farmed in the water with adding the poly-valence pyobacteriophage and fed by compound feed treated by the preparation. It has been found that the dominant position in the intestinal microbiocenosis of red tilapia belongs to Micrococcus bacteria, whose share made 45.7% of all isolates of the gastrointestinal tract.

By the frequency of occurrence, the second place is taken by the Bacterium species (33.2%), the third place - Staphylococcus (16.1%) species. The remaining groups of intestinal microorganisms are presented by a significantly number of isolates. It has been stated that the gills microflora was represented by a smaller species composition compared to the digestive tract microbiota. Isolates of the Bacterium and Staphylococcus bacteria were dominating, while the Actinomycetales and Bacillus microorganisms were represented in smaller numbers (1-2 colonies). The addition of a bacteriophage to water and its processing of compound feed helps to reduce the contamination of gills and reduce pathogenic microflora in the intestines of fish.

Authors: MAMYCHEV Alexey , KAZACHANSKAYA Elena , GARASHKO Anna
Published: December 2021

This paper examines the value-normative transformation of the modern social system and analyzes the impact of digitalization processes on social relations and their development. The content of the article substantively analyzes the key areas of digitalization of social relations; the authors mark out in each of these areas positive and negative effects on the sustainable development of the socio-cultural integrity of society. The empirical material used in this work includes expert assessments and analytical materials related to the digital transformation of traditional religious systems and the value-normative foundations of society. The research perspectives presented in this paper evaluate and interpret all the events and processes under consideration from the conservative legal point of view, from the standpoint of the significance of the socio-cultural environment, sustainable traditional institutions and values for coding and predicting the digital transformation of society in the 21st century.
In the conclusion of the study, the authors substantiate the adequacy of the doctrinal and legal model of society’s development called “digital etatism” from the perspective of ensuring stable socio-cultural development and the integrity of the social system.

Complications, prognostic factors, and long-term outcomes for dogs with brachycephalic obstructive airway syndrome that underwent H-pharyngoplasty and ala-vestibuloplasty: 423 cases (2011–2017)
Authors: Carabalona Julien P.R. , Le Boedec Kevin , Poncet Cyrill M.
Published: December 2021

OBJECTIVE

To describe the H-pharyngoplasty procedure, report the outcomes of dogs with brachycephalic obstructive airway syndrome (BOAS) treated with ala-vestibuloplasty and H-pharyngoplasty with a CO2 laser, and identify prognostic factors.

ANIMALS

423 dogs.

PROCEDURES

Medical records of dogs admitted for BOAS from 2011 to 2017 were reviewed. Dogs were included if they were treated with ala-vestibuloplasty and H-pharyngoplasty with a CO2 laser. Signalment, physical examination findings, grades at admission of clinical signs associated with respiratory and digestive systems, diagnostic test results, postoperative treatments, and short-term follow-up results were extracted from medical records. Long-term follow-up of > 12 months was evaluated via questionnaire. Generalized ordered logistic regression was used for bivariable and multivariable analyses.

RESULTS

Overall mortality rate was 2.6%. Median duration of follow-up was 36 months (12 to 91 months), and 341 (80.6%) dog owners completed the questionnaire. Major complications included respiratory distress (2.1%), heatstroke (0.5%), and bronchopneumonia (0.5%). No dogs required revision surgery. Improvement in signs associated with the respiratory and digestive systems was reported in 72% and 34% of the dogs, respectively, and owners’ satisfaction was high (97.1%). Risk of death increased by 29.8% (95% CI, 11.8% to 50.7%) for every 1-year increase in age.

CONCLUSION AND CLINICAL RELEVANCE

H-pharyngoplasty was possible in all dogs with BOAS, including those previously treated with conventional surgery and was associated with low morbidity and improved respiratory and digestive signs. H-pharyngoplasty combined with ala-vestibuloplasty may be an alternative treatment for even the most severely affected dogs.

Published: December 2021

OBJECTIVE

To describe a modified approach to closed anal sacculectomy and report the short-term outcomes of dogs that underwent the procedure for treatment of neoplasia.

ANIMALS

16 client-owned dogs.

PROCEDURES

Medical records of 1 referral hospital were reviewed to identify dogs that underwent modified closed anal sacculectomy for treatment of anal sac neoplasia between January 2018 and September 2020. Data collected included signalment, examination and diagnostic imaging findings, surgical details, intraoperative and postoperative complications, cytologic and histologic findings, adjuvant treatments, duration of follow-up, and short-term outcome.

RESULTS

15 dogs had apocrine gland anal sac adenocarcinoma, and 1 had a collision tumor. No dogs had intraoperative complications; 1 dog had a minor postoperative complication (paraparesis) that resolved. The median duration of postoperative follow-up was 286 days (range, 67 to 777 days). One dog had confirmed local disease recurrence 290 days after surgery, and 1 had suspected local disease recurrence 203 days after surgery and was euthanized because of systemic disease progression.

CONCLUSIONS AND CLINICAL RELEVANCE

The modified closed anal sacculectomy was well tolerated in this sample of dogs, with minimal short-term complications. This study provided evidence to justify evaluation of the procedure in a larger number of dogs and assessment of the effects of procedural modifications on postoperative complication rates and time to local recurrence.

Published: December 2021

OBJECTIVE

To compare effectiveness of maropitant and ondansetron in preventing preoperative vomiting and nausea in healthy dogs premedicated with a combination of hydromorphone, acepromazine, and glycopyrrolate.

ANIMALS

88 dogs owned by rescue organizations.

PROCEDURES

Dogs received maropitant (n = 29) or ondansetron (28) PO 2 hours prior to premedication or did not receive an antiemetic (31; control). Dogs were evaluated for vomiting, nausea, and severity of nausea (scored for 6 signs) for 15 minutes following premedication with hydromorphone, acepromazine, and glycopyrrolate.

RESULTS

A significantly lower percentage of dogs vomited after receiving maropitant (3/29 [10%]), compared with control dogs (19/31 [62%]) and dogs that received ondansetron (15/28 [54%]). A significantly lower percentage of dogs appeared nauseated after receiving maropitant (3/29 [10%]), compared with control dogs (27/31 [87%]) and dogs that received ondansetron (14/28 [50%]), and a significantly lower percentage of dogs appeared nauseated after receiving ondansetron, compared with control dogs. Nausea severity scores for hypersalivation, lip licking, hard swallowing, and hunched posture were significantly lower for dogs that received maropitant than for control dogs, and scores for hypersalivation, lip licking, and hard swallowing were significantly lower for dogs that received ondansetron than for control dogs.

CONCLUSIONS AND CLINICAL RELEVANCE

Oral administration of maropitant 2 hours prior to premedication with hydromorphone reduced the incidence of vomiting and the incidence and severity of nausea in healthy dogs. Oral administration of ondansetron reduced the incidence and severity of nausea but not the incidence of vomiting.
