A preliminary study of the original TIBSIT and its cultural adaptation in Malaysia.

BACKGROUND: A simple and self-administered 'scratch & sniff' test kit like the TIBSIT smell kit based on the Taiwan Smell Identification Test (TWSIT), provides a safe and quick assessment of olfaction. The original TIBSIT has been validated for use in Taiwan with age specific scores for different age groups and diagnosis. The main aim of this study is to examine if TIBSIT can be applicable for the Malaysian population and perform cultural adaptation as necessary to allow a more accurate assessment using this tool. 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).

The Malay version of smartphone addiction scale: Development, factor structure and validation of a short form for Malaysian adolescents.

INTRODUCTION: This study aimed to validate the Malay version of the short form Smartphone Addiction Scale (SAS-M-SF) and to examine its psychometric properties in a cohort of pre-university adolescents. METHODS: We obtained the validity and reliability evidence for the SAS-M-SF using a group of 307 pre-university students in Universiti Putra Malaysia (UPM), Serdang, Selangor, Malaysia with a mean age of 18.4±0.2 years (70.4% female and 29.6% male). A questionnaire containing the Malay version of Smartphone Addiction Scale (SAS-M), the Malay version of the short form Smartphone Addiction Scale (SAS-M-SF), and the Malay version of the Internet Addiction Test (IAT-M) was administered on the adolescents. RESULTS: The SAS-M-SF displayed good internal consistency (Cronbach's α=0.80). Using principle component analysis, we identified a 4-factor SAS-M-SF model. A significant correlation between the SAS-M-SF and the IAT-M was found, lending support for concurrent validity. The prevalence of smartphone addiction was 54.5% based on cut-off score of ≥36 with a sensitivity of 70.2% and a specificity of 72.5%. CONCLUSIONS: The 10-item SAS-M-SF is a valid and reliable screening tool for smartphone addiction among adolescents. The scale can help clinicians or educators design appropriate intervention and prevention programs targeting smartphone addiction in adolescents at clinical or school settings.

Carbonic anhydrase IX immunohistochemistry has potential to predict renal cell carcinoma outcomes: A systematic review and meta-analyses.

INTRODUCTION: Tissue biomarker carbonic anhydrase IX (CAIX) is purported to have prognostic value for renal cell carcinoma (RCC) but contradicting findings from previous studies have also been documented. This study aims to perform a systematic review and meta-analysis on the role of CAIX in RCC disease progression. MATERIALS AND METHODS: Following the preferred reporting items for systematic review and meta-analysis (PRISMA) guidelines, online searches of multiple databases were performed to retrieve articles from their inception until December 2017. Inclusion criteria included all English-based original articles of immunohistochemistry (IHC) studies investigating CAIX expression in human RCC tissue. Four articles were finally selected for meta-analysis with a total of 1964 patients. Standard meta-analysis methods were applied to evaluate the role of CAIX in RCC prognosis. The relative risk (RR) and its 95% confidence interval (CI) were recorded for the association between biomarker and prognosis, and data were analysed using MedCalc statistical software. RESULTS: The meta-analysis showed that high CAIX expression was associated with low tumour stage (RR 0.90%, 95% CI 0.849-0.969, p= 0.004), low tumour grade (RR 0.835%, 95% CI 0.732-0.983, p= 0.028), absence of nodal involvement (RR 0.814%, 95% CI 0.712-0.931, p= 0.003) and better ECOS-PS index (RR 0.888%, 95% CI 0.818-0.969, p= 0.007). The high tissue CAIX expression in RCC is hence an indication of an early malignancy with a potential to predict favourable disease progression and outcome. CONCLUSION: The measurement of this marker may be beneficial to determine the course of the illness. It is hoped that CAIX can be developed as a specific tissue biomarker for RCC in the near future.
