Authors: Aoun Ahmed H. , Aon Mohamed H. , Alshammari Abdulrahman Z. , Moussa Shady A 
Published: August 2021

Background:
Coronavirus disease 2019 (COVID-19) vaccine development is the best approach to fight the disease. However, rising vaccine hesitancy can make widespread vaccine application difficult.

Objectives:
To explore health care workers' attitudes towards the COVID-19 vaccine and find the reasons lying behind vaccine hesitancy among participants.

Methods:
Our study was a cross-sectional survey. An anonymous online questionnaire was sent to a sample of health care workers living and working in the Middle East region. Data collected included demographic data, educational attainment, household crowding, risk factors for severe COVID-19 infection, influenza vaccination history, and questions about COVID-19 vaccine acceptance.

Results:
We received 864 validated responses. The study included 365 physicians, 391 nurses, and 108 allied professions. Females represented 61% of participants and 98.5% of participants were below 65 years old. Around 60% of participants were hesitant to get the COVID-19 vaccine. The commonest reasons for hesitancy were lack of information and fear of side effects. Vaccine acceptance was higher among males (p< 0.001), physicians (p= 0.017), participants with medical risk factors (p= 0.017), and participants vaccinated against influenza (p< 0.001). After control for other factors, male (OR, 1.94; CI 1.42-2.66), married participant (OR, 1.89; CI 1.22-2.92), living in a less crowded accommodation (OR, 1.33; CI 1.11-1.59), and who got influenza vaccine (OR, 1.64; CI 1.13-2.37) tended to accept the COVID-19 vaccine more likely.

Conclusion:
Rates of vaccine hesitancy among health care workers were high. The current pandemic offers an opportunity to establish better vaccine confidence towards the COVID-19 vaccine and vaccines in general.

Authors: Shin Bokyoung , Oh Jooyoung , Kim Byung-Hoon , Kim Hesun Erin , Kim Hyunji , Kim Suji , Kim Jae-Jin 
Published: August 2021

Background
Virtual reality (VR) is as effective a technique as traditional cognitive behavioral therapy (CBT) and a promising tool for treating panic disorder symptoms because VR exposure can be safer and has better acceptability than in vivo exposure and is more immersive than exposure through imagination. CBT techniques can be delivered more effectively using VR as well. So far, VR has required high-quality devices, but the development of mobile VR technology has improved user availability. At the same time, a well-structured form of VR can be reproduced and used anywhere. This means that VR can be used to provide a self-guided form of treatment and address the high treatment costs of evidence-based therapy and the lack of professional therapists. This study aimed to investigate the potential of self-guided VR as an alternative to high-cost treatment.

Objective
The main goal of this study was to offer data about the efficacy of a mobile app-based self-led VR CBT in the treatment of panic disorder.

Methods
A total of 54 subjects with panic disorder were enrolled in this study and randomly assigned to either the VR treatment group or waitlist group. The VR treatment was designed to be total 12 sessions for 4 weeks. The VR treatment consists of 4 steps in which patients are gradually exposed to phobic stimuli while learning to cope with panic symptoms in each stage. The effectiveness of treatment was assessed through the Panic Disorder Severity Scale, Hamilton Rating Scale for Depression, Body Sensations Questionnaire, Albany Panic and Phobia Questionnaire, Anxiety Sensitivity Index, State-Trait Anxiety Inventory, Hospital Anxiety and Depression Scale, Korean Inventory of Social Avoidance and Distress Scale, Korean Inventory of Depressive Symptomatology, and Perceived Stress Scale. In addition, physiological changes using heart rate variability were evaluated.

Results
In within-group analyses, the VR treatment group exhibited improvements in panic disorder symptoms, anxiety, and depression after 4 weeks, while the waitlist group did not show any significant improvement. Compared to the waitlist group, the VR treatment group showed significantly greater improvements in the Panic Disorder Severity Scale in both completer analysis and intention-to-treat analysis. Heart rate variability in the VR treatment group showed improvement in normalized high frequency from baseline to postassessment with no significant differences in any outcome measure between groups.

Conclusions
The self-guided, mobile app-based VR intervention was effective in the treatment of panic symptoms and restoring the autonomic nervous system demonstrating the validity of the use of VR for self-guided treatment. VR treatment can be a cost-effective therapeutic approach.

Introduction. Primary cardiac tumors are rare, and the autopsy detection rate does not exceed 0.003%. Approximately 80% of primary heart tumors are benign, 50% of them are myxomas. Diagnosis of cardiac tumors at present in the presence of transesophageal echocardiography is not difficult in most cases. Surgical treatment of mixomas became possible after the introduction of open-heart surgery under cardiopulmonary bypass into clinical practice. After verification of the tumor, its surgical removal is indicated. In the practice of large cardiac surgery clinics, the experience of radical treatment of heart neoplasms is relatively small; therefore, the analysis of tactical approaches and results of operations in this pathology is of absolute interest.Aim of study. To present an analysis of 10 years’ experience in surgical treatment of cardiac mixomas. Material and methods The results of treatment of 58 patients with myxomas who underwent surgical removal of the neoplasm of the heart are presented.Results. Hospital mortality after surgical removal of myxoma was 1.7%, 1 patient died. All patients, we have the long-term period data about, noted a significant improvement in well-being, a decrease or disappearance of dyspnea at rest and/or during exertion, and no recurrence of myxoma was noted. Conclusion. The data obtained indicate, on the whole, good immediate results and high quality of life of patients in the long-term period operated on for heart mixomas.

Randomized, blinded, controlled clinical trial to assess gastroesophageal reflux and regurgitation in dogs undergoing general anesthesia after hydromorphone premedication with or without acepromazine or dexmedetomidine
Authors: Costa Renata S. , Wetmore Lois A. , Stein Amy 
Published: August 2021

Abstract

OBJECTIVE
To investigate whether premedication with hydromorphone alone or combined with acepromazine or dexmedetomidine affects the incidence of gastroesophageal reflux (GER) and regurgitation in dogs undergoing general anesthesia for elective orthopedic surgery.

ANIMALS
39 healthy client-owned dogs undergoing general anesthesia for elective orthopedic surgery between November 2016 and November 2018.

PROCEDURES
For this prospective, randomized, controlled, blinded clinical trial, dogs were randomly assigned to be premedicated with hydromorphone (0.1 mg/kg, IM) alone (group H [control group]) or with either acepromazine (0.05 mg/kg, IM; group AH) or dexmedetomidine (6 μg/kg, IM; group DH) before undergoing general anesthesia induced with propofol and maintained with isoflurane. A pH sensor–tipped probe was used to identify episodes of GER (esophageal pH < 4 or > 7.5 for ≥ 30 seconds). Results for GER, regurgitation, vomiting, propofol dose, and durations of food withholding and anesthesia were compiled and compared across groups.

RESULTS
There were 13 dogs in each group, and no meaningful differences were detected in age, body weight, sex, breed, or durations of anesthesia or food withholding across groups. Overall, 16 of the 39 (41%) dogs developed GER: 9 in group H, 6 in group AH, and 1 in group DH. The incidence of GER was significantly lower for group DH versus group H. Six of the 39 (15%) dogs regurgitated: 4 in group H and 2 in group AH.

CONCLUSIONS AND CLINICAL RELEVANCE
The combined use of dexmedetomidine and hydromorphone as premedication may be a better choice to reduce GER in healthy dogs undergoing orthopedic surgery than would the use of hydromorphone with or without acepromazine. Additional research is warranted. (Am J Vet Res 2021;82:695–700)

Abstract

Flight services at Fatmawati Soekarno Airport, located in Bengkulu City, continue to develop, along with the increasing public need for air transportation. The increasing need for aviation services affects the number and types of aircraft required. Aircraft maneuvering and parking affect the dimensions of the aircraft parking space. In this study, an analysis of the dimensions of the apron at Fatmawati Soekarno Airport was carried out, with a service life of 20 years. The analysis in this study was carried out using the design aircraft B737-900ER. The existing apron dimension lot is 475 m long and 80 m wide. By using the International Civil Aviation Organization method and the Federal Aviation Administration method, to accommodate aircraft movements for the next 20 years, an apron with a length of 475 m and a width of 100 m is required. Thus, the width of the existing apron must be increased by 20 m, in order to be able to serve the B737-900ER aircraft until the service life of the next 20 years.

Published: August 2021

At the end of 2019, the COVID-19 disease emerged in the city of Wuhan, China, and caused an outbreak of unusual viral pneumonia. Being highly transmissible, this novel coronavirus disease has spread fast all over the world. COVID-19 continues to challenge most developed countries in the search for an effective strategy to either prevent infection or to avoid the spreading of the disease. While several developed countries have managed to contain COVID-19, several countries in Latin America continue to report an increase in the daily number of infected people. Ecuador, particularly, became the epicenter of the COVID-19 outbreak in the region during March and April 2020. In this context, the present study shows a simple mathematical approach to understand the effect of the COVID-19 outbreak in Ecuador (and some Latin American countries such as Brazil, Peru, and Colombia). The proposed method is based on the exponential model, discrete logistic equation, and differential logistic model using one-year data from March 1, 2020, to February 28, 2021. This study presents the estimated growth rate coefficient (λ), the total number of cases (N), and the midpoint of maximum infection (t_0) as well as the variability of the λ coefficient as a function of total cases and time. The exponential model shows a high value of λ=0.185 which decreases to λ=0.014 and λ=0.056 according to the discrete and differential logistic models, respectively. An accurate value of the total number of cases of infected people was found by analyzing the number of daily cases as a function of the total of cases whose value (N~409 K) agrees with the data reported at the end of May 2021, validating the proposed approach. How to use the current mathematical approach for long-term prediction is also discussed here. Most importantly, the proposed method has two important characteristics: (i) the mathematical model is as simple as possible compared to other time-consuming approaches, and (ii) it can be used to study the effect of COVID-19 and predicts its consequences in other countries, allowing revenue new decisions against the COVID-19 disease.
