METHOD AND MATERIAL: A preliminary study of the original TIBSIT (Phase 1) followed by cultural adaption (Phase 2) were carried out on volunteers from various neighbourhoods in Klang Valley, Malaysia comprising of age group 16-80 years. A total of 150 test subjects and 50 test subjects were recruited for Phase 1 and Phase 2 respectively. Cultural adaptation was done with changes to the distractors that were found to be confusing. In addition, modifications included added language translation and visual reinforcement with images of the odour's substance of origin.
RESULTS: 109 out of the 150 responses were accepted for Phase 1. A detection rate of less than 75% was found in three of the odours with the remaining showing an average rate of 87.2% to 97.7%. These three odours were culturally adapted for Phase 2. All 50 responses for Phase 2 were accepted; two of the odours' detection rates improved to 98% but the plum odour was only detected 53% of the time.
CONCLUSION: TIBSIT provides a quick office-based olfaction testing. The culturally adapted test kit is a potentially useful screening test for the Malaysian population. It is also safe and excludes the need of the clinician to carry out the test. This becomes especially useful in testing any dysosmia (hyposmia/anosmia) cases suspected of SARS-COV-2 virus infection (COVID-19).
METHODS: We piloted a COVID-19 smell clinic. We recorded patient demographics and clinical characteristics then performed clinical assessment of each patient. Quantitative measurements of olfactory dysfunction were recorded using the University of Pennsylvania Smell Identification Test (UPSIT). We measured the impact of olfactory dysfunction on patient quality of life using the validated English Olfactory Disorders Questionnaire (eODQ).
RESULTS: 20 patients participated in the clinic. 4 patients were excluded from analysis due to missing data. Median age was 35 years. 81% (n=13) of the participants were female. 50% (n=8) of patients suffered with a combination of anosmia/ageusia and parosmia, whilst 43% (n=7) of patients suffered with anosmia/ageusia without parosmia. Almost all the patients registered UPSIT scores in keeping with impaired olfaction. Patient scores ranged from 22 to 35, with the median score at 30. All patients reported that their olfactory dysfunction had an impact on their quality of life. The median eODQ score reported was 90, with scores ranging from 42 to 169 out of a maximum of 180.
CONCLUSION: We have demonstrated that it is simple and feasible to set up a COVID-19 smell clinic. The materials are inexpensive, but supervised completion of the UPSIT and eODQ is time-consuming. Patients demonstrate reduced olfaction on quantitative testing and experience significant impacts on their quality of life as a result. More research is needed to demonstrate if olfactory training results in measurable improvements in smell test scores and quality of life.
METHODS: All patients who underwent TNO guided biopsies or dilatation attempted over a 7 month period during COVID- 19 pandemic were included by searching the hospital and department database at The Royal Albert Edward Infirmary. A comparative group of patients who underwent panendoscopy over 9 months were included for comparison. Demographic data, histological diagnosis, second procedure and cost involved were recorded.
RESULTS: During this period, 20 TNO procedures (16 biopsies and 4 dilatations) were attempted which were compared with 20 panendoscopy procedures. The diagnostic accuracy of TNO biopsy for identifying benign and malignant pathology was 81.1%. The sensitivity and specificity for identifying malignancy was 76.9% and 100% respectively. The most common lesion location was laryngeal (43.8%) followed by oropharyngeal (37.5%), more specifically located at the tongue base. The median waiting period between the procedure being listed and TNO being performed was 5.5 days compared to 12 days for panendoscopy. There were 12/16 patients who did not require further interventions for histological diagnosis of the tumor. The TNO procedure was well tolerated with no complications and all were done under local anaesthesia as outpatient procedure without need for admission. TNO resulted in cost saving of £356 per case on a standard NHS tariff.
CONCLUSION: TNO is a valuable diagnostic tool for patients with suspected UADT malignancy and dysphagia and has proven to be an asset during the COVID-19 pandemic when we have to make the best use of the limited theatre time and resources. Also, the cost analysis showed that outpatient based TNO can provide significant cost savings for the current standard of care. Furthermore, it has shown better patient tolerability, lesser complications and shortened the time for diagnosis and hence starting timely treatment for these patients.
DESIGN AND METHODS: The model is an improvement of the susceptible, infected, recovery, and death (SIRD) compartmental model. The epidemiological parameters of the infection, recovery, and death rates were formulated as time dependent piecewise functions by incorporating the control measures of lockdown, social distancing, quarantine, lockdown lifting time and the percentage of people who abide by the rules. An improved SIRD model was solved via the 4th order Runge-Kutta (RK4) method and 14 unknown parameters were estimated by using Nelder-Mead algorithm and pattern-search technique. The publicly available data for COVID-19 outbreak in Malaysia was used to validate the performance of the model. The GUI-based SIRD model was developed to simulate the number of active cases of COVID-19 over time by considering movement control order (MCO) lifted date and the percentage of people who abide the rules.
RESULTS: The simulator showed that the improved SIRD model adequately fitted Malaysia COVID-19 data indicated by low values of root mean square error (RMSE) as compared to other existing models. The higher the percentage of people following the SOP, the lower the spread of disease. Another key point is that the later the lifting time after the lockdown, the lower the spread of disease.
CONCLUSIONS: These findings highlight the importance of the society to obey the intervention measures in preventing the spread of the COVID-19 disease.
OBJECTIVE: To evaluate the prevalence of burnout, assess the personal and professional characteristics associated with burnout in spine surgeons and determine their quality of life.
SUMMARY OF BACKGROUND DATA: Burnout is a syndrome characterized by emotional exhaustion, depersonalization, and decreased sense of accomplishment that leads to decreased effectiveness at work. To date, there has been a lack of information on the prevalence of burnout among spine surgeons worldwide and the risk factors associated with this condition.
METHODS: An electronic survey with members of AO Spine was performed in May 2018. The survey evaluated demographic variables, practice characteristics, burnout, and quality of life. Maslach Burnout Inventory (MBI) and EuroQol 5-dimensions (EQ5D) were used to evaluate burnout and quality of life, respectively.
RESULTS: A total of 818 surgeons from 86 countries completed the survey. The prevalence of burnout was 30.6%. In the multiple linear model, emotional fatigue was independently associated with younger age (B = -0.17, CI95% = -0.26 to -0.07, P
