Abstract From June 28 to November 22, 2018, the Chinese People’s Liberation Army Navy – PLA(N) – Peace Ark hospital ship had conducted Mission Harmony 2018, providing humanitarian medical assistance and carrying out international cooperation, in 4 Pacific island countries and 6 Central and South American countries. Compared with its application only in onshore outreach medical teams in the previous Mission Harmony, portable ultrasonography was used both onboard and onshore in Mission Harmony 2018. The purpose of this study was to assess the performance of onboard portable ultrasonography in PLA(N) Peace Ark hospital ship during Mission Harmony-2018, share our onboard working experience, and provide a reference for humanitarian assistance missions in the future. A retrospective review was performed on a cohort of patients checked by onboard portable ultrasonography. Patients’ gender, age, the distribution of examined organs, and multiple applications of the portable ultrasonography were analyzed. Some limitations of portable ultrasonography on the mission and possible improvements in the future were also discussed. A total of 5277 cases (mean age: 43.74 years; range: 2 months–105 years) of ultrasound examinations were performed during the mission; among them, 3126 (59.2%) cases were performed by portable ultrasonography, including 3024 onboard cases and 102 onshore cases. The portable ultrasonography had been applied in many scenarios, for example, onboard emergency triage process, onboard bedside medical support, and onshore outreach medical service, which had become one of the indispensable auxiliary examination methods for its compatibility, portability, and flexibility. The onboard deployment of portable ultrasonography played a versatile and irreplaceable role in the humanitarian medical assistance and medical cooperation carried out by the PLA(N) Peace Ark hospital ship, and will contribute to such kind of missions in the future.

INTRODUCTION Nearly 1 in 40 of the population seeks medical advice related to a shoulder problem every year. The majority pertain to rotator cuff pathology. Prior to intervention in such patients it is imperative to define whether the tendons are intact or torn. Ultrasonography has become an essential adjunct to clinical assessment in diagnosing rotator cuff tears. This study was designed to investigate if a surgeon using a portable ultrasonography machine in a one-stop shoulder clinic could significantly reduce the time a patient waited from initial outpatient presentation to the end of the treatment episode (be it surgery, injection or conservative management). METHODS A total of 77 patients were allocated to one of two groups: Group A, consisting of 37 patients who were assessed and had ultrasonography as outpatients, and Group B, consisting of 40 patients who were assessed and referred for departmental ultrasonography where appropriate. Three clear outcome groups were defined: those who required surgical repair, those who had irreparable tears and those who declined surgery. RESULTS For all outcomes (surgery, irreparable tears and conservative treatment), the patients in Group A all completed their clinical episodes significantly quicker than those in Group B (p<0.02). As well as the time saving benefits, there was a substantial financial saving for Group A. By performing ultrasonography in the outpatients department, those patients avoided the requirement of departmental imaging (£120) and subsequent follow-up appointments (£73) to discuss results and management, resulting in a saving of nearly £200 per patient. CONCLUSIONS The use of a portable ultrasonography machine by an orthopaedic surgeon can significantly reduce the time to treatment and the financial cost for patients with rotator cuff tears.

Background According to the rapid response system’s team composition, responding teams were named as rapid response team (RRT), medical emergency team (MET), and critical care outreach. A RRT is often a nurse-led team, whereas a MET is a physician-led team that mainly plays the role of an efferent limb. As few multicenter studies have focused on physician-led METs, we comprehensively analyzed cases for which physician-led METs were activated. Methods We retrospectively analyzed cases for which METs were activated. The study population consisted of subjects over 18 years of age who were admitted in the general ward from January 2016 to December 2017 in 9 tertiary teaching hospitals in Korea. The data on subjects’ characteristics, activation causes, activation methods, performed interventions, in-hospital mortality, and intensive care unit (ICU) transfer after MET activation were collected and analyzed. Results In this study, 12,767 cases were analyzed, excluding those without in-hospital mortality data. The subjects’ median age was 67 years, and 70.4% of them were admitted to the medical department. The most common cause of MET activation was respiratory distress (35.1%), followed by shock (11.8%), and the most common underlying disease was solid cancer (39%). In 7,561 subjects (59.2%), the MET was activated using the screening system. The commonly performed procedures were arterial line insertion (17.9%), intubation (13.3%), and portable ultrasonography (13.0%). Subsequently, 29.4% of the subjects were transferred to the ICU, and 27.2% died during hospitalization. Conclusions This physician-led MET cohort showed relatively high rates of intervention, including arterial line insertion and portable ultrasonography, and low ICU transfer rates. We presume that MET detects deteriorating patients earlier using a screening system and begins ICU-level management at the patient’s bedside without delay, eventually preventing the patient’s condition from worsening and transfer to the ICU.

Background Although magnetic resonance imaging (MRI) is often the “gold standard” for diagnosing knee problems, it has many limitations. Therefore, ultrasonography has been suggested as an effective rapid alternative in many knee abnormalities, especially after injuries of the meniscus and collateral ligaments. Purpose To determine the diagnostic accuracy of point-of-care ultrasound (POCUS) in detecting injuries of the meniscus and collateral ligament compared to MRI. Material and Methods An observational cross-sectional blinded study was conducted of 60 patients with clinically suspicious meniscus and collateral ligament injuries who were planned for an arthroscopy and or operative procedure. These patients underwent both blinded POCUS and MRI of the knees before the intervention procedure and results of both imaging modalities were compared according to the operative and arthroscopic findings. Results The preoperative reliability of POCUS compared to MRI for the assessment of meniscus injuries was sensitivity (92.9% vs. 90.5%), specificity (88.9% vs. 83.3%), positive predictive value (PPV; 95.1% vs. 92.7%), negative predictive value (NPV; 84.2% vs. 79%), and overall accuracy (91.7% vs. 88.3%). However, for diagnosing collateral ligament injures, POCUS versus MRI assessed sensitivity (92.3% vs. 88.5%), specificity (100% vs. 97.1%), PPV (100% vs. 95.8%), NPV (94.4% vs. 91.7%), and overall accuracy (96.7% vs. 93.3%). Conclusion Ultrasonography is a useful screening tool for the initial diagnosis of meniscal and collateral ligament pathology compared to or even with potential advantages over MRI, especially when MRI is unavailable or contraindicated. As newly advanced portable ultrasonography becomes available, it could be considered as a point-of-injury diagnostic modality.

The objective of this research was to determine the minimum area representative of the testicular parenchyma echotexture in Nelore bulls, and to evaluate the presence of echotexture homogeneity between the right and left testicles and between different regions of testicle. Twenty-nine Nelore bulls raised under extensive management and free of reproductive disorders were used. The average body weight was 352.8 ± 51.0 kg and age ranged between 18 and 24 months. Echotexture was assessed using a portable ultrasonography device equipped with a 7.5-MHz linear transducer. All measurement was done by a single, experienced operator, and scanner settings that affect image attributes (i.e. proximal, distal, and total gains; focus area; brightness and contrast) were standardized to predetermined values. In the examinations, a layer of gel was applied to the transducer scanning area, which was positioned in the testicular longitudinal plane, proceeding with enough pressure to capture an image. The frozen images were obtained with minimal artifacts (refraction, dispersion, and attenuation of ultrasound waves) taking care to avoid the mediastinum testis and tunica albuginea, and recorded as .bmp files in a USB pen drive connected to the ultrasound device. Echotexture was defined in terms of mean pixel value quantified using values from 0 (black) to 255 (white) through the ImageJ 1.41 software. After the selection of a specific area of testicular parenchyma, the average tonality of the gray pixels in the selected region was calculated by the software and expressed in 256 gray-scales. Squares selections of 400 (20 × 20), 1600 (40 × 40), 3600 (60 × 60), and 6400 (80 × 80) pixels were assessed from images of the extremitas capitata, middle, and extremitas caudata regions of both testicles to determine the minimum sampling area of an image needed to represent the echotexture of testicular parenchyma. The normal distribution verification (Lilliefors test) of the variable mean pixel value was tested in each area, followed by variance analysis. The averages were compared through Tukey’s test with 5% significance. There was no significant difference between the different pixel areas assessed (P > 0.05), indicating that all were samples representative of testicular echotexture. Furthermore, the extremitas capitata, middle, and extremitas caudata regions showed no significant difference in echotexture (P > 0.05) regardless of the area analyzed, and there was no significant difference between the right and left testicles (P > 0.05) in any of the assessed areas. In conclusion, this research shows that testicular echotexture assessments can be made in Nelore bulls through selections of 400, 1600, 3600, or 6400 pixels, and that images can be captured from any region of any testicle.
