Intensive Care Consultant: Superhero or normal human being but more capable!

Submission content Introduction: Intensive care medicine has become an admired, loved, hated, and definitely more interesting Specialty due to a special situation (COVID-19) that exposed the training process to numerous criticisms, positives, and negatives, and this is how I believe we could improve our beloved world. Proposal: 1. Ideal training program from medical school to Certificate of Completion of Training (CCT): * Medical school: In their last year they should do more than 1 week in the Intensive Care Unit (ICU) * Stage 1: there should be a core surgical training of at least 6 months * Stage 2: there should be a rotation on Psychiatry of at least 4 weeks with on calls in ICU and 2 weeks in Palliative Care * Stage 3: acting as a consultant for the last six months on ST7 with backup from a formal consultant, and * Surgical training should be included in the possible dual or triple CCT 2. How would we be assessed? I agree with the Faculty of Intensive Care Medicine (FICM) staging program assessment, with some modifications: * As ST7 the trainee should act as a consultant with back support at least 50% of the stage and need to be evaluated by a Multi-Source Feedback (MSF). * Clinical Fellows should have a consultant as a Certificate of Eligibility for Specialist Registration (CESR) guide who establishes the equivalent stage of training supporting them and assessing them under the same model. * Changing the way, the General Medical Council (GMC) conducts the CESR application and making it really equivalent to the ICM training with the FFICM curriculum. 3. What do we need to be taught? * Hot topics for ICU (academic), * Overseas talks to share experiences, * Ultrasound (FUSIC), * Wellbeing strategies, * Leadership training * Psychiatric and physiological effects post ICU for patients and staff, * The administrative and political model of the National Health Service (NHS), and * Communication skills to establish excellent relationships with the other specialties. 4. What would our working life look like? * Normal day: 8 am to 3 pm * Midday shift: 1 pm to 8:30 pm * Night shift: 8 pm to 8:30 am * A rolling rota of 12 weeks with 2 weekends during this time 5. How would you produce Intensive Care Medicine (ICM) Consultants of the future who both love their job and their life: * Starting with less intense shifts, * More cordial relationships between the teams, * Supporting ICM trainees and Fellows going through their CESR pathway, * Making the training more attractive to either male-female doctors getting them involved in as many different specialties as ICM can cover, Conclusion(s): Having full-time ICM Consultants should be welcome in all ICUs in the country, which is not at the moment. This will definitely attract a lot of excellent doctors who are 100% focused on ICM.

Effects of endoscopic reprocessing on disinfection and its influential factors during coronavirus disease 2019 pandemic.

Objective To explore the effects of endoscopic reprocessing on disinfection and its influential factors under the coronavirus disease 2019 (COVID-19) pandemic. Methods A total of 450 endoscopes cleaned and disinfected according to Technical Specifications for Cleaning and Disinfection of Endoscopes from November 2019 to January 2020, and 450 endoscopes cleaned and disinfected according to The recommended procedure for cleaning and disinfection of gastrointestinal endoscopes during COVID-19 epidemic by Chinese Society of Digestive Endoscopology from February to April 2020 in the Second Affiliated Hospital of Chongqing Medical University were enrolled in the control group and observation group respectively by random number method. Both the control group and the observation group contained 200 gastroscopes, 200 enteroscopes and 50 ultrasound endoscopes. ATP fluorescence detection method and pour plate technique were used to evaluate the disinfection effect of endoscopes. Single factor analysis and multiple logistic regression were used to analyze the risk factors for unqualified sterilization after endoscopic reprocessing. Results The disinfection pass rates of gastroscopes, enteroscopes and ultrasound endoscopes in the observation group were not significantly different compared with those of the control group (P>0. 05). The sterilization pass rates and ATP test pass rates of gastroscopes, enteroscopes and ultrasound endoscopes in the observation group were significantly higher than those in the control group (all P<0. 05). Multivariate logistic regression analysis showed that non-strict implementation of endoscopic reprocessing (OR = 7. 96, 95%CI: 4. 55-22. 84, P<0. 001), non-standard operation (OR = 2. 26, 95%CI: 1. 24-5. 63, P<0. 001), insufficient concentration of disinfectant (OR = 5. 43, 95% CI: 2. 52-9. 02, P < 0. 001), insufficient concentration ratio of multi-enzyme solution (OR = 4. 38, 95% CI: 1. 95-8. 61, P < 0. 001), non-timely cleaning (OR= 2. 86, 95%CI: 1. 33-6. 42, P<0. 001), incomplete cleaning (OR = 3. 75, 95%CI: 1. 61-7. 49, P<0. 001) and improper endoscopic preservation (OR= 2. 12, 95%CI: 1. 36-4. 12, P<0. 001) were independent risk factors for unqualified sterilization after endoscopic reprocessing. Conclusion In COVID-19 pandemic, endoscope reprocessing can significantly improve the disinfection effect of endoscopes, worthy of further clinical promotion. The failure to strictly implement the reprocessing procedure is an important factor that may lead to unqualified sterilization.Copyright © 2021 The authors.

Acute or chronic? Failing left ventricle in a 34 year old

Submission content Introduction: An unusual case of a very young patient without previously known cardiac disease presenting with severe left ventricular failure, detected by a point of care echocardiogram. Main Body: A 34 year old previously well man was brought to hospital after seeing his general practitioner with one month of progressive shortness of breath on exertion. This began around the time the patient received his second covid-19 vaccination. He was sleeping in a chair as he was unable to lie flat. Abnormal observations led the GP to call an ambulance. In the emergency department, the patient required oxygen 5L/min to maintain SpO2 >94%, but he was not in respiratory distress at rest. Blood pressure was 92/53mmHg, mean 67mmHg. Point of care testing for COVID-19 was negative. He was alert, with warm peripheries. Lactate was 1.0mmol/L and he was producing more than 0.5ml/kg/hr of urine. There was no ankle swelling. ECG showed sinus tachycardia. He underwent CT pulmonary angiography which demonstrated no pulmonary embolus, but there was bilateral pulmonary edema. Troponin was 17ng/l, BNP was 2700pg/ml. Furosemide 40mg was given intravenously by the general medical team. Critical care outreach asked for an urgent intensivist review given the highly unusual diagnosis of pulmonary edema in a man of this age. An immediate FUSIC Heart scan identified a dilated left ventricle with end diastolic diameter 7cm and severe global systolic impairment. The right ventricle was not severely impaired, with TAPSE 18mm. There was no significant pericardial effusion. Multiple B lines and trace pulmonary effusions were identified at the lung bases. The patient was urgently discussed with the regional cardiac unit in case of further deterioration, basic images were shared via a cloud system. A potential diagnosis of vaccination-associated myocarditis was considered,1 but in view of the low troponin, the presentation was felt most likely to represent decompensated chronic dilated cardiomyopathy. The patient disclosed a family history of early cardiac death in males. Aggressive diuresis was commenced. The patient was admitted to a monitored bed given the potential risk of arrhythmia or further haemodynamic deterioration. Advice was given that in the event of worsening hypotension, fluids should not be administered but the cardiac centre should be contacted immediately. Formal echocardiography confirmed the POCUS findings, with ejection fraction <35%. He was initiated on ACE inhibitors and beta adrenergic blockade. His symptoms improved and he was able to return home and to work, and is currently undergoing further investigations to establish the etiology of his condition. Conclusion(s): Early echocardiography provided early evidence of a cardiac cause for the patient's presentation and highlighted the severity of the underlying pathology. This directed early aggressive diuresis and safety-netting by virtue of discussion with a tertiary cardiac centre whilst it was established whether this was an acute or decompensated chronic pathology. Ultrasound findings: PLAX, PSAX and A4Ch views demonstrating a severely dilated (7cm end diastolic diameter) left ventricle with global severe systolic impairment.

Automatic Detection of Lung Ultrasound Artifacts using a Deep Neural Networks approach

The COVID-19 pandemic has challenged many of the healthcare systems around the world. Many patients who have been hospitalized due to this disease develop lung damage. In low and middle-income countries, people living in rural and remote areas have very limited access to adequate health care. Ultrasound is a safe, portable and accessible alternative;however, it has limitations such as being operator-dependent and requiring a trained professional. The use of lung ultrasound volume sweep imaging is a potential solution for this lack of physicians. In order to support this protocol, image processing together with machine learning is a potential methodology for an automatic lung damage screening system. In this paper we present an automatic detection of lung ultrasound artifacts using a Deep Neural Network, identifying clinical relevant artifacts such as pleural and A-lines contained in the ultrasound examination taken as part of the clinical screening in patients with suspected lung damage. The model achieved encouraging preliminary results such as sensitivity of 94%, specificity of 81%, and accuracy of 89% to identify the presence of A-lines. Finally, the present study could result in an alternative solution for an operator-independent lung damage screening in rural areas, leading to the integration of AI-based technology as a complementary tool for healthcare professionals. © 2023 SPIE.

Coronavirus disease (COVID-19) in patients with type 2 diabetes mellitus: clinical and laboratory peculiarities

This study aims to study the clinical-laboratory peculiarities of the coronavirus disease (COVID-19) course in patients with type 2 diabetes mellitus (DM). There were examined 60 patients with the coronavirus disease COVID-19. Patients were divided into two groups: group I - 30 patients with the coronavirus disease (COVID-19) with concomitant type 2 diabetes mellitus;group II - 30 patients with coronavirus disease (COVID-19) without diabetes mellitus;control group - 20 people. There were studied peculiarities of clinical-laboratory changes in patients with coronavirus disease with type 2 diabetes mellitus. General clinical laboratory tests, determination of biochemical parameters, coagulogram, ferritin, CRP, procalcitonin, D-dimer and endothelin-1 were performed. Blood saturation was measured. Out of the instrumental methods, an ultrasound examination of the lungs and RTG of thoracic organs was performed. Patients were admitted on the 5.46+/-0.87 day of the disease. The length of the hospital stay for patients of group I was 19.9+/-1.66 bed days and 14.7+/-0.91 bed days for the patients of group II. A severe course of the disease was observed in 83.3% of patients of group I and 33.3% of group II;a moderate severity course was observed in 16.7% of patients with concomitant DM and 66.7% of patients without concomitant DM. Respiratory failure (RF) of 1 degree was observed in 30% of patients of group 1, RF of the 2 degree - in 16.7% of patients, and RF of the 3 degree - in 10% of patients. In patients without DM, RF of 1 degree - was in 30% of patients, and RF of the 2 degree - was in 13.3% of patients. The laboratory diagnostic methods determined that the levels of leukocytes, D-dimer, endothelin-1, IL-6, procalcitonin, and ferritin were higher in patients with concomitant type 2 DM. In patients with type 2 DM, the course of the coronavirus disease is more severe and longer, with the development of pneumonia and respiratory failure. It is accompanied by leukocytosis, lymphopenia, increased ESR, prothrombin index, IL-6, CRP level, procalcitonin and endothelin-1. Copyright © 2023 The Authors.

AVASCULAR NECROSIS OF THE FEMORAL HEAD – NOT TO BE OVERLOOKED SEQUELA AFTER COVID 19 INFECTION

BackgroundCOVID 19 infection could lead to different sequelae in survivors, known as post-COVID or long COVID 19 syndromes. Some of them are thought to be due to the thrombophylic changes observed in COVID 19 infection, but some are thought to be caused by the administrated (especially high dose) corticosteroid treatment. Avascular necrosis of the femoral head (AVNFH) is a multifactorial disease which leads to compromised vascular supply, ischemia and finally necrosis of the femoral head. As corticosteroids usage and thrombophylic states are among the main known risk factors for the development AVNFH [1], it could be presumed that the frequency of this disease will increase with the COVID 19 pandemic. The exact corticosteroid dose needed for the development of AVNFH is not clear, but it has been stated that a higher daily dose and a larger total cumulative dose increase substantially the risk for the development of osteonecrosis [2].ObjectivesTo describe in detail the characteristics of AVNFH diagnosed in patients after COVID 19 infection.MethodsThe study was done in a tertiary university rheumatological clinic. Data was extracted from the records of patients who have been referred to the clinic because of hip pain between June and December 2022. Inclusion criteria were: - a new onset of uni-or bilateral hip pain that started after a documented COVID 19 infection;and an MRI scan of the hip joints showing osteonecrosis of one or both femoral heads. Exclusion criteria were the presence of hip pain prior to the COVID 19 infection, anamnesis of traumatic injuries of the hips or pelvis, personal history of hypercoagulable states.ResultsNine patients (4 women and 5 men) with an average age 59.1 years (range 38-72) were included in the study. Four patients had been diagnosed with bilateral and five – with unilateral AVNFH, thus 13 hip joints were analysed in total (8 left and 5 right sided). The mean time lap between the COVID 19 infection and the start of the hip pain was 26.2 weeks (range 10-48 weeks). All patients had limited and painful movement in their symptomatic hip(s), especially internal rotation and four of the patients had also elevated CRP levels (mean 11.7 mg/L). The stage of the AVNFH was evaluated according to the Ficat-Arlet classification (0-IV stage). In four hips the AVNFH was stage I, five hips were classified as stage II and the remaining four joints - as stage III. All symptomatic hip joints exhibited effusion/synovitis on both ultrasound examination and the corresponding MRI scan. It should be noted that the presence of hip effusion was found to be related with a worse prognosis in AVNFH [1]. In three patients the amount of the effusion required arthrocentesis and fluid aspiration. The analysis of the joint fluid was consistent with a degenerative disease (i.e., low WBC count with predominant lymphocytes and no crystals). All patients included in our study had received corticosteroids during their COVID19 infection, while 6 of the patients had also been hospitalized due to more severe disease. According to the patients' documentation, the mean cumulative dose of the received corticosteroids was 936.2 mg prednisolone equivalent per patient (range 187-2272 mg).ConclusionAVNFH must not be overlooked in a new onset hip pain after COVID 19 infection. Our results show that corticosteroids administrated during the infection and the presence of hip joint effusion on ultrasound are especially suggestive for the development of osteonecrosis, as they were registered in all of our patients. The presence of these two factors necessitates patient referral for an MRI scan of the hips, in order that AVNFH be detected timely.References[1]Petek D, Hannouche D, Suva D.

Medical intensivist directed VV ECMO cannulation for the facilitation of tracheostomy in a patient with severe tracheal stenosis: A case report

Objectives: We present a case report of medical intensivist driven ECMO program using ECMO as a pre-procedural tool to maintain oxygenation in a patient with critical tracheal stenosis during tracheostomy placement. Method(s): VV ECMO is primarily used to support patients when mechanical ventilation is unable to provide adequate gas exchange. Alternatively, it has been used pre-procedurally when intubation is required in anticipation of a difficult airway. Described here is the first intensivist preformed awake VV ECMO cannulation to facilitate tracheostomy in a patient with severe tracheal stenosis. Result(s): The patient is a 41-year-old female with the relevant background of COVID19 pneumonia status post tracheostomy and subsequently decannulated after prolonged intubation and ICU stay. As a result, the patient developed symptomatic tracheal stenosis and presented two years after her ICU stay for scheduled bronchoscopy and balloon dilation. However, the patient developed worsening stridor and shortness of breath requiring heliox and BPAP. After multidisciplinary discussion between the critical care team ENT teams, the decision was made to cannulate for VV ECMO as a pre-procedural maneuver to allow for oxygenation during open tracheostomy in the OR. Dexmedetomidine and local anesthesia were used for the procedure with the patient sitting at 30 degrees on non-invasive ventilation and heliox. The patient was cannulated with a 21F right internal jugular return cannula and 25F right common femoral drainage cannula by medical intensivists in the intensive care unit using ultrasound guidance. The patient went for operative tracheostomy the next day and was subsequently decannulated from ECMO the following day without complication. She was discharged home on trach collar. Conclusion(s): Intensivist performed ECMO cannulation has been shown to be safe and effective. We anticipate the indications and use will continue to expand. This case is an example that intensivist driven preprocedural ECMO is a viable extension of that practice.

Nanosponges: As a Dynamic Drug Delivery Approach for Targeted Delivery

Recent advancements in nanotechnology have resulted in improved medicine delivery to the target site. Nanosponges are three-dimensional drug delivery systems that are nanoscale in size and created by cross-linking polymers. The introduction of Nanosponges has been a significant step toward overcoming issues such as drug toxicity, low bioavailability, and predictable medication release. Using a new way of nanotechnology, nanosponges, which are porous with small sponges (below one microm) flowing throughout the body, have demonstrated excellent results in delivering drugs. As a result, they reach the target place, attach to the skin's surface, and slowly release the medicine. Nanosponges can be used to encapsulate a wide range of medicines, including both hydrophilic and lipophilic pharmaceuticals. The medication delivery method using nanosponges is one of the most promising fields in pharmacy. It can be used as a biocatalyst carrier for vaccines, antibodies, enzymes, and proteins to be released. The existing study enlightens on the preparation method, evaluation, and prospective application in a medication delivery system and also focuses on patents filed in the field of nanosponges.Copyright © 2023 The Authors.

A Freehand 3D Ultrasound Carotid Scanning System for Point-of-Care Ultrasonography

Stroke is a leading cause of morbidity and mortality throughout the world. Three-dimensional ultrasound (3DUS) imaging was shown to be more sensitive to treatment effect and more accurate in stratifying stroke risk than two-dimensional ultrasound (2DUS) imaging. Point-of-care ultrasound screening (POCUS) is important for patients with limited mobility and at times when the patients have limited access to the ultrasound scanning room, such as in the COVID-19 era. We used an optical tracking system to track the 3D position and orientation of the 2DUS frames acquired by a commercial wireless ultrasound system and subsequently reconstructed a 3DUS image from these frames. The tracking requires spatial and temporal calibrations. Spatial calibration is required to determine the spatial relationship between the 2DUS machine and the tracking system. Spatial calibration was achieved by localizing the landmarks with known coordinates in a custom-designed Z-fiducial phantom in an 2DUS image. Temporal calibration is needed to synchronize the clock of the wireless ultrasound system and the optical tracking system so that position and orientation detected by the optical tracking system can be registered to the corresponding 2DUS frame. Temporal calibration was achieved by initiating the scanning by an abrupt motion that can be readily detected in both systems. This abrupt motion establishes a common reference time point, thereby synchronizing the clock in both systems. We demonstrated that the system can be used to visualize the three-dimensional structure of a carotid phantom. The error rate of the measurements is 2.3%. Upon in-vivo validation, this system will allow POCUS carotid scanning in clinical research and practices. © 2023 SPIE.

lungEcho - Resource Constrained Lung Ultrasound Video Analysis Tool for Faster Triaging and Active Learning

Lung ultrasound (LUS) is possibly the only medical imaging modality which could be used for continuous and periodic monitoring of the lung. This is extremely useful in tracking the lung manifestations either during the onset of lung infection or to track the effect of vaccination on lung as in pandemics such as COVID-19. There have been many attempts in automating the classification of the severity of lung involvement into various classes or automatic segmentation of various LUS landmarks and manifestations. However, all these approaches are based on training static machine learning models which require a significantly large clinically annotated dataset and are computationally heavy and are most of the time non-real time. In this work, a real-time light weight active learning-based approach is presented for faster triaging in COVID-19 subjects in resource constrained settings. The tool, based on the you look only once (YOLO) network, has the capability of providing the quality of images based on the identification of various LUS landmarks, artefacts and manifestations. This tool also predict the severity of lung infection and make use of the possibility of active learning based on the feedback from clinicians or on the image quality. The capability of this tool to summarize the significant frames which are having high severity of infection and high image quality will be helpful for clinicians to discern things more easily. The results show that the proposed object detection tool has a mean average precision (mAP) of 66% at an Intersection over Union (IoU) threshold of 0.5 for the prediction of LUS landmarks with initial training on less than 1000 images. The 14MB lightweight YOLOv5s network achieves 123 FPS while running on a Quadro P4000 GPU. The tool is available for usage and analysis upon request from the authors and details can be found online.

TELEDIDACTIC MUSCULOSKELETAL ULTRASOUND COURSE AND COMPARISON WITH CONVENTIONAL ON-CAMPUS TRAINING – INTERIM ANALYSIS OF THE TELMUS STUDY

BackgroundMusculoskeletal ultrasound (MSUS) is increasingly gaining importance as an imaging tool in rheumatology. Most training programs currently address resident doctors. However, several studies have demonstrated that teaching MSUS to medical students improves their palpation skills and understanding of musculoskeletal anatomy. With the development of portable ultrasound devices, MSUS education is lately getting more flexible and location-independent. In addition, the COVID-19 pandemic raised awareness of telemedicine training as a powerful tool to ensure the teaching of practical skills under pandemic conditions.ObjectivesThe purpose of our study is to establish a telemedical MSUS course for medical students and to compare its effectiveness with a conventional on-campus course as a world-wide pilot study. In doing so, we aim to expand student educational opportunities in MSUS using innovative teaching options while ensuring quality maintenance of teaching.MethodsThirty medical students were randomized to either a virtual group being delivered only telemedicine instructions, or an on-campus cohort receiving the course in a conventional format. Each student was provided with a handheld ultrasound device. Prior to the start of the course, the students' skills were assessed with an Objective Clinical Structured Examination (OSCE). During the course, a DEGUM-III-certified course instructor taught the basic physics of ultrasound and standard sections of the MUDE ultrasound protocol[1]. In order to quantify the students' learning progress, a second OSCE was carried out after completion of the course. [1].ResultsAt the time of this analysis, data collection within the on-campus course has already been completed, whereas the virtual course is still ongoing. While the average score of the students in the PRE-course OSCE was 21,02% (SD ±6,78), the students were able to achieve an average of 90% (SD ±6,81) in the POST-course OSCE after the intervention.ConclusionWith the results obtained so far, it can be shown that an innovative course concept with hand-held ultrasound devices, originally developed for dermatologists to improve the detection of psoriatic arthritis, can be used very well in student teaching without major modifications and leads to a significant increase in MSUS skills among medical students. The TELMUS study thereby offers a successful example of extending an existing course concept to student teaching and thus promoting the next generation of rheumatologists.Reference[1]Grobelski J, Recker F, Wilsmann- Theis D, et al.

THE CURRENT SITUATION OF MUSCULOSKELETAL ULTRASOUND EDUCATION - A SYSTEMATIC LITERATURE REVIEW

BackgroundThe use of musculoskeletal ultrasound improves patient care by increasing diagnostic and therapeutic safety. With its growing application and increasing evidence of its value, the demand for standardized training in musculoskeletal ultrasonography (MSUS) rises rapidly.ObjectivesIn this systematic literature review, we aim to provide a general overview of the various aspects of musculoskeletal ultrasound education worldwide, including target groups, teaching staff, didactic methods, and course formats, as well as to reflect on existing problems and future opportunities. No restrictions were made regarding the educational level of the course recipients nor the specialization of the course instructors.MethodsIn our methodological approach, we followed the PRISMA statement for reporting systematic reviews and meta-analyses of studies[1]. In January 2022, the databases Embase, PubMed, and Google Scholar were considered with all publications to date and were filtered for relevant publications using previously defined keywords. Title and were then screened independently by two authors for inclusion using relevant study characteristics determined in advance according to the PICO scheme[1]. Finally relevant information was filtered from the full text version of the sixty-seven included publications.ResultsThe range of training programs has increased greatly in recent years, primarily aiming at residents in rheumatology, radiology and physical medicine and rehabilitation. However, MSUS is also receiving more attention as a training tool for medical students. Due to the COVID pandemic, didactic approaches using distance learning via simulators and handheld devices have gained additional importance. Given the existing lack of sufficient equipment and trained teaching staff, those approaches should continue to be explored post-pandemic. Another still existing problem is the low international comparability of MSUS training and competency assessment. Therefore, several international institutions, including the European League Against Rheumatism (EULAR) and the Pan-American League of Associations for Rheumatology (PANLAR) have proposed guidelines for training curricula to promote standardized ultrasound training.ConclusionThere is a broad consensus that the development of standardized curricula improves training and facilitates the implementation of new training centers. The development of alternative teaching methods incorporating e-learning, peer teaching, and distance learning on mobile ultrasound devices and the determination of international guidelines could facilitate overcoming the remaining major obstacles still to be passed.Reference[1]Liberati A, Altman DG, Tetzlaff J, et al.

Evaluation of Lung Ultrasound in Assessment of Critically Ill patients in Respiratory Intensive Care Unit

Reaching a proper diagnosis for critically ill patients is like collecting pieces of puzzle and bed side lung ultrasound (LUS) becomes a crucial piece complementary to clinical and laboratory pieces. It is a bed side, real time tool for diagnosis of patients in ICU who are critical to be transferred to radiology unit especially in Covid-19 pandemic with risk of infection transmission. The aim was to evaluate the accuracy of lung ultrasound in assessment of critically ill patients admitted to Respiratory Intensive Care Unit (RICU), moreover to assess its diagnostic performance in different pulmonary diseases as compared to the gold standard approach accordingly. This observational prospective (cross sectional) study with a total 183 patients who met the inclusion criteria,were selected from patients admitted at the RICU;Chest Department, Zagazig University Hospitals, during the period from September 2019 to September 2021. LUS examination was performed to diagnose the different pulmonary diseases causing RF. All cases were examined by LUS on admission. From a total 183 patients, 111 patients 60.7% were males and 72 patients 39.3% were females, with a mean age of 56+/-12.77 years, 130 patients were breathing spontaneously received conservative management with O2 therapy, 32 patients needed NIV while 21 patients needed IMV with ETT. Exacerbated COPD was the most common disease finally diagnosed followed by bacterial pneumonia, exacerbated ILD, post Covid-19 fibrosis and pulmonary embolism in32, 29,27, 19 and 11 patients respectively with corresponding diagnostic accuracy of LUS 97.3%, AUC=0.943, 93.9% (AUC=0.922), 96.7%(AUC=0.920), 97.8%, AUC=0.895, and 97.8% respectively, while Covid-19 pneumonia was the final diagnosis in 8 patients with LUS diagnostic accuracy of 97.8% (AUC=0.869) with no statistical significant difference p-value=0.818 with bacterial pneumonia in distribution of US profiles. A profile was the commonest detected US profile among the studied patients followed by B profile, C profile, A/B profile and A' profile in 37.2%, 24.6%, 15.8% 4.9%, and 3.8% of cases respectively. Bed side LUS has a reliable, valuable diagnostic performance when integrated with clinical and laboratory data for the diagnosis of most pulmonary diseases in RICU.Copyright © 2023, Colegio de Farmaceuticos de la Provincia de Buenos Aires.

A breath of fresh air

Submission content Introduction: This is a story about the day I wheeled a patient outside. I know, it sounds somewhat underwhelming. But little did I know that this short trip down a hospital corridor and beyond the entrance foyer would mark a profound shift in perspective both for me and my patient, which I hope will influence me for the rest of my career. Main Body: "Paul" was in his 50s and severely afflicted by COVID-19, resulting in a protracted ICU admission with a slow and arduous ventilator wean. Throughout his time on the unit, Paul had seen no daylight;no view of the outside world. He was struggling to make progress and was becoming exasperated. His deteriorating mood in turn affected his sleep, which further undermined his progress. Due to COVID-19, visiting was not permitted and Paul's cuffed tracheostomy meant that he couldn't speak to his family. One day, witnessing Paul's psychological decline, I asked him if he fancied a trip outside. Despite initial reluctance, he eventually gave in to some gentle persuasion from the staff nurse, with whom he had developed a close bond. So there we went;Paul, his nurse and me. And as we wheeled his bed through the door into open air, Paul's whole demeanour suddenly changed. He appeared as though the weight of the world had been lifted from his shoulders and his face lit up with awe, a tear emerging in the corner of his eye. In that moment he rediscovered life. Not as a hospital patient, but as a person. Watching the world go by, he remembered what it was like to be a member of the human race, not the subject of endless tests and treatments. He tasted freedom. Conclusion(s): Awakened by his experience of the forgotten outside world, when we eventually returned to the ICU Paul was an entirely different man. To Paul, the trip outside symbolised progress. After weeks of frustration and despair, he finally had a purpose;a motivation to get better. Meanwhile, I was having my own quiet realisation. I now understood what it truly meant to deliver holistic care. It can become all too easy to focus on the clinical aspects;to obsess about the numbers. But in fact, often what matter most to patients are the 'little things', to which no amount of medication is the solution. I now try to consider during my daily review: what matters to this patient? How are they feeling? What are they thinking? What else can I do to help their psychological recovery? And as for me personally? Having witnessed Paul's reaction to the outside world, I suddenly became aware of how little attention I normally pay to the world around me. How little I appreciate the simple ability to walk outside, and the fundamental things we take for granted. Now, when I'm feeling annoyed or frustrated about something trivial, I stop and think of Paul. I then thank my lucky stars for what I have to be grateful for. Ultrasound Ninja.

Ultrasound of Covid 19

We present how we used ultrasound to improve our diagnosis of lung Covid 19 and use ultrasound to diagnose the complications of Covid 19. Ultrasound was more sensitive in detecting early Covid 19 than chest radiograph. The complications of Covid 19 include renal impairment, liver impairment and vascular complications, mainly large vessel venous thrombosis, including renal vein thrombosis. We are all suffering from post-viral fatigue but lessons can be learnt from this pandemic and the use of ultrasound.

CHALLENGES FOR PATIENTS WITH RMD'S IN BULGARIA DURING THE COVID-19 PANDEMIC

BackgroundThe Covid-19 pandemic has put patients with rheumatic diseases in front of a number of obstacles that had to be solved together with Bulgarian rheumatologists. The lockdowns and restrictive measures have made it difficult for people with rheumatic diseases to have access to timely hospital and pre-hospital care. A number of digital solutions have been implemented to address these issues.ObjectivesTo highlight the problems that patients with rheumatic diseases had during the Covid-19 pandemic;access to rheumatologists and the effectiveness of hospital and pre-hospital care during the pandemic, access to treatment, changes of treatment;communication between physicians and patients, the impact of the pandemic on work, social contacts, hobbies.MethodsAn anonymous survey was conducted online and by telephone. The survey was developed by Medical university, Plovdiv, University hospital "Kaspela”:, Plovdiv, Bulgarian Association for Musculoskeletal Ultrasound, Bulgarian organization for people with rheumatic diseases;Association for patients with autoimmune diseases.Number of participants: 1205 patients with RMD's.Age range: 18-82ResultsFace to face meetings with doctors have been limited during the pandemic.Visits to the rheumatologist's office are significantly reduced and phone, email, text messaging, online consultations were preferred as communication channels.Before the pandemic, 76% of respondents most often communicated with their physicians by visiting their practice, during the pandemic their relative share decreased to 46%, with a significant difference of 30%Phone consultations: patients using this type of communication increasing from 38% before the pandemic to 56% during the pandemic, a significant difference of 18%The percentage of patients who communicated via text or email rises from 10% to 17 %.It has become apparent that Digital transformation is needed and patients and physicians should work together to achieve it and to be established in Bulgaria.245 patients reported a change in their treatment. Of these: (30%) reduced the dose of their medications, 119 (49%) increased the dose and the remaining 55 (21%) stopped their therapy.From the responses of the respondents, it is clear that 71% have not experienced a change in their work during the COVID-19 pandemic, 17% have worked from home.From the responses of the respondents, it is clear that 71% have not experienced a change in their work during the COVID-19 pandemic, 17% have worked from home, 4% have been fired, 3% have left their jobs due to the risk of their health and 5% left their jobs for other reasons.ConclusionThe Covid-19 pandemic has shown that the digital transformation in rheumatology care can be an efficient alternative to some of the services offered to patients with rheumatic diseases in Bulgaria (especially secondary examinations and therapy monitoring examinations). The results of the conducted survey could be used to support digitization in healthcare in Bulgaria.Very important was the collaboration between the patient organizations and the Bulgarian Association for Musculoskeletal Ultrasound, Medical University, Plovdiv and the rheumatologists from University hospital "Kaspela” Plovdiv.References[1]Gianfrancesco M, Hyrich KL, Al-Adely S, et al.

Recent advances in the effect of ultrasound on the binding of protein−polyphenol complexes in foodstuff

Foodstuff is a complex system that consists of a variety of nutrients. Protein is the basis of human life and health, which is made up of amino acids combined in different proportional orders. Polyphenols are a class of small molecule active substances with strong pro-life health effects. It has been found that protein and polyphenols can be combined by covalent and non-covalent interactions to form complex delivery carriers. The interaction between the two can effectively improve the physiological activities of proteins and enhance the bio-accessibility of polyphenols. With the maturation of ultrasound technology, several studies have shown that ultrasound can promote the production of protein−polyphenol complexes. To promote the study of protein–polyphenol interactions in foodstuff by ultrasound technology, the preparation methods of protein−polyphenol complexes, the effects of ultrasound on complex generation, and analytical methods were systematically summarized based on an extensive literature review, and further research directions were proposed. It provides the reference for the ultrasound study of protein−polyphenol complexes.

The incidence of deep vein thrombosis following COVID-19 vaccination in an Australian population

Introduction: After the COVID-19 vaccination roll out in March 2021 patients began presenting to a Victorian Emergency Department with lower limb pain following their vaccination. As a result, requests for ultrasound examinations, to exclude post vaccination deep vein thrombosis (DVT) began appearing. Method(s): A retrospective study of ultrasound examinations and their result over a 1-year period was undertaken. Patients were identified who had a clinical indication of having been referred following COVID-19 vaccination. Bivariate analysis was conducted, using logistic regression, to determine the strength of association between independent variables. Result(s): The study found 1689 patients had a lower limb DVT ultrasound examination. Ultrasound was positive for DVT in 244/1689 patients (14.4%). 104/1689 (6.1%) patients presented for ultrasound following COVID-19 vaccination. Six of these were found to have DVT detected. The association between post vaccination and DVT was an odds ratio (OR) of 0.347 (95% CI 0.150 to 0.799, p = 0.013). All patients had recently received AstraZeneca (AZ) vaccine. Four patients were diagnosed with superficial vein thrombosis (SVT) post vaccination. Nineteen patients were identified as COVID-19 positive. Three of these had DVT detected. Conclusion(s): This study found 6 patients out of 1689 (0.35%) of lower limb ultrasound examinations over a one-year period, were positive for DVT after COVID-19 vaccination. Take home message: The results showed post vaccination patients were less likely to be diagnosed with a DVT than the population referred who had not had recent vaccination.

IDDF2023-ABS-0005 Hepatocellular carcinoma (HCC) treatment experience using smart fusion in dialysis patients

BackgroundApproximately 700 dialysis patients are seen at our hospital. Among them are patients with HCC that develop viral hepatitis. Advances in ultrasound systems have improved the accuracy of HCC treatment and diagnosis. This time, we had the opportunity to use microwaves for dialysis patients using Smart Fusion and needle navigation installed in APLIOi800 so that we will report it.MethodsTen dialysis patients were treated from January 2018 to February 2023. An Emprint (Covidien, USA) antenna was used for treatment. Canon APLIOi800(Canon, Tochigi, Japan) was used. The built-in function is Smart Fusion. This method can display ultrasound imaging and volume data from other modalities, such as CT and MRI, in association with positional information using a magnetic sensor. Needle navigation has a function that can confirm the position of the needle. It is possible to treat even when the tumor is overprinted and the visualization is poor due to bubbles. Informed consent was obtained from all patients and the treatment was performed.ResultsIt was possible to visualize all tumors. In this study, CT images were used in 0 cases, and MRI was used in 1 Case. No serious side effects occurred after treatment.ConclusionsUsing this method, it was thought that dialysis patients could be safely and accurately treated.
