METHODS: This is a prospective, randomised, crossover, single-blinded study conducted from February 2018 to February 2019 among adult subjects attending respiratory clinic Universiti Kebangsaan Malaysia Medical Centre (UKMMC).
RESULTS: Forty-six subjects were recruited with 27 males (58.7%). The mean age was 54 (+11) year old. The baseline median Body Mass Index (BMI) was 34.2 kg/m2 (Interquartile Range IQR: 30.8 kg/m2 -41.7 kg/m2); baseline median AHI 28.8 /hour (IQR 21.2/hour-54.0/hour); andbaseline median ESS 15 (IQR 13-16). After intervention, the median AHI was 5.0 / hour (IQR 4.2/hour-6.0/hour) at fixed CPAP arm; APAP arm was 5.5/ hour (IQR 4.2/hour-6.3/hour); p<0.01. The median ESS at fixed CPAP arm was 2 (IQR 0-3); APAP arm was 2 (IQR 1-3); p < 0.01. Those who preferred APAP were 22 subjects (47.8%) and had median optimal CPAP pressure 13.0 cmH2O (IQR 12.0 cmH2O -13.5 cmH2O); 24 subjects (52.2%) who preferred Fixed CPAP had median optimal CPAP pressure 8.0 cmH2O (IQR 6.3 cmH2O -8.7 cmH2O); p<0.01. Median baseline BMI was 37.6 kg/m2 (IQR 30.8 kg/m2 -43.0 kg/m2) for those who preferred APAP and 32.3 kg/m2 (IQR 30.8 kg/m2 - 38.4 kg/m2) for subjects preferred Fixed CPAP; p=0.03.
DISCUSSION: Fixed CPAP maybe considered as first line therapy for symptomatic moderate and severe OSA with titrated optimal CPAP pressure less than 8 cmH2O and BMI less than 32.3 kg/m2; based on subjects' preference. Baseline AHI and average daily CPAP usage was not statisticallysignificant in affecting patient preference between fixed and auto adjusting CPAP. This is the first study of its kind conducted in Malaysia.
METHODS: This was a parallel, open-label randomised controlled trial with participants recruited from psychiatric outpatient services of a teaching hospital in Kuala Lumpur and a secondary hospital in Melaka. Adults (≥18 years) diagnosed with major depressive disorder; capable of reading and understanding English or Bahasa Malaysia; prescribed with at least one antidepressant and owns a smart phone were subsequently randomly assigned (1:1) to receive treatment reminders (intervention) or standard treatment without reminders (control), using a computergenerated randomisation programme. The intervention group received two reminder categories: Outpatient appointment reminders (a day before appointment); and medication reminders (weekly basis). Participants were followed-up over two months. We utilised Montgomery- Asberg Depression Rating Scale (MADRS) to measure the severity of depression; and Brief Adherence Rating Scale (BARS) to assess medication adherence. Primary outcomes were outpatient attendance rates and medication adherence assessed at two months. Secondary outcomes included changes in depression severity within each group at two months; comparison of changes in depression severity between both groups; preferences of participants towards treatment reminders, and reasons for non-attendance among participants. This trial was registered with the National Medical Research Registry, NMRR-19-3466-52001.
RESULTS: Between February and April 2020, 183 participants were randomised to each group, of whom 179 reached study endpoint (91 [98.9%] of 92 in intervention group and 88 [96.7%] of 91 in control group). All recruited participants (n=183) were analysed using intention-to-treat approach. At two months, intervention group has significantly higher outpatient attendance rates (76.8%) than control group (56.4%) (p=0.002), and reported higher medical adherence percentage (mean difference 23.1, [95%CI 0.4, 35.8]; p<0.001). There was also significant difference in the MADRS score change between both groups (mean difference 3.4, [95%CI 0.4, 6.3]; p=0.025). Treatment reminders preferences among participants varied; forgetfulness was the most commonly reported reason (53%) for missing outpatient appointments.
CONCLUSION: Reminders through mobile messaging applications significantly improved outpatient attendance and medication adherence among patients with depression. Our findings support the use of messaging apps for treatment reminders in psychiatric outpatient settings. However, concerns regarding confidentiality require careful measures to be taken.
METHODS: An observational controlled study comparing neonatal respiratory morbidities before and after the single dose 12mg dexamethasone was implemented in our obstetrics and gynaecology centre for term elective caesarean section deliveries. We included singleton pregnancies from 37+0 to 38+6 weeks undergoing elective caesarean section into our study. A total of 674 patients fulfilled the inclusion criteria and were recruited. We compared the rates and duration of admission to neonatal intensive care unit, the need for mechanical ventilation and the rate of transient tachypnoea of the newborn in the first half of 2019 without IM dexamethasone injections against the second half of the year when a single dose IM dexamethasone was given.
RESULTS: IM dexamethasone injection did not show any significant benefit with regards to reducing the admission to neonatal care (OR 0.97, p- value 0.69), admission to neonatal intensive care unit (OR 0.91, p- value 0.80), the need for mechanical ventilation (OR 0.98, p- value 0.95), and the incidence of transient tachypnoea of the newborn (OR1.01, p- value 0.96). There was also no significant difference for the duration of admission in the neonatal intensive care unit for both groups (p- value 0.17).
CONCLUSIONS: This study showed that there was no significant benefit gained from the lower dose antenatal corticosteroids for term elective caesarean section deliveries and considering that there have been long term harmful consequences demonstrated from the higher dose of antenatal corticosteroids at term, this practice should therefore be discontinued until a larger study is done to refute these findings. The use of such dexamethasone should only be a viable option in a research setting.
METHODS: This retrospective study was conducted in Hospital Seri Manjung, Perak, Malaysia. All cases of blood culture proven PB that occurred between 1st January 2015 and 31st December 2019 were reviewed. Subjects below 12 year old and whose index blood cultures grew more than one organism were excluded. Demographic, clinical and treatment data were collected using pre-tested data collection forms and analysed using SPSS version 20.0.
RESULTS: Among the 59 subjects included, healthcare associated (HCA) infections were the most prevalent, next to hospital onset (HO) and community onset (CO) infections. The commonest underlying comorbidities were cardiovascular disease, diabetes mellitus, and chronic kidney disease. Respiratory tract was the most frequently implicated source amongst all, while the urinary tract was more frequently implicated as the source of infection among HCA cases. Seventeen patients were admitted to ICU, and they were predominantly from the HO group. Despite having a higher rate of adequate empirical antibiotics administered, the HO group reported the lowest 30-day survival rate. Multiple logistic regression analysis demonstrated the following were independent predictors of 30-day mortality: requiring mechanical ventilator support, requiring central venous line insertion, not requiring surgery, and receiving inappropriate definite antibiotics.
CONCLUSION: The incidence of community onset PB was appreciably low, as cases were predominantly HCA and HO in origin. Significant morbidities were observed among pseudomonal infections, with HO infections portending the worst prognosis. Lastly, prognostic factors for determining the mortality caused by PB depended more on the severity of sepsis than the timeliness of appropriate antibiotics.
MATERIALS AND METHODS: This study was conducted based on the guideline published by the European Association of Nuclear Medicine (EANM) version 2.0 FDG-PET/CT and conducted in two phases. Firstly, 100 whole-body scan 18FFDG PET/CT images were selected for the average coefficient of variation (COV) analysis in the liver region. Second, a NEMA 2012/IEC2008 phantom was used to obtain the relationship between the COVphantom and the scanning time. Finally, the images acquired using the two Tmin were quantitatively compared using contrast recovery coefficient (QH), signal to noise ratio (SNR), and visibility (VH). Independent t-test between each image quality parameter performed with p-value <0.05 considered significant.
RESULTS: The average COV of the liver was 17.7%. Currently, this value was clinically accepted to produce appropriate image quality at IKN. Interpolation at COV=17.7% gave a Tmin value of 2.9 minutes. Comparisons show that the two Tmin yielded equivalent PET/CT image quality (p-value of QH=0.774, SNR=0.780 and VH=0.915).
CONCLUSION: The optimal Tmin defined in this study was 2.9 minutes, 27.6% shorter than the Tmin previously defined based on COV=15%. Despite the higher average COV, the shorter Tmin beneficial in the lower total 18F-FDG activity administered, reduce the internal dose to the patient while producing equivalent image quality.
METHODS: A cross-sectional study was conducted involving patients aged ≥ 13 years with AD who fulfilled the Hanifin and Rajka diagnostic criteria. These patients were recruited from Hospital Queen Elizabeth, Kota Kinabalu and Hospital Kuala Lumpur between January 2020 to March 2021. Assessment instruments used were Scoring for Atopic Dermatitis (SCORAD), Patient-Oriented Eczema Measure (POEM), Dermatology Life Quality Index (DLQI) and Hospital Anxiety and Depression Scale (HADS).
RESULTS: Of the 217 participants, 75 (34.6%) had mild eczema, 116 (53.5%) moderate eczema and 26 (12.0%) severe eczema with a mean SCORAD score of 30.4 (standard deviation [SD] = 4.70). Twenty-six (12.0%) and 17 (7.8%) had anxiety and depression, respectively. Patients with moderate to severe disease reported higher HADS-A (HADS-anxiety component), HADS-D (HADS-depression component), POEM, DLQI, itch, sleep loss and skin pain scores (p < 0.001 for all). Severe sleep loss (adjusted odd ratio [AOR] 12.41, p < 0.001) and hospitalisation in the past year (AOR 6.44, p = 0.004) were significant predictors for anxiety whereas those aged 41 to 60 (AOR 10.83, p = 0.020), having severe skin pain (AOR 6.12, p = 0.028), DLQI ≥ 10 (AOR 5.27, p = 0.002) and history of hospitalisation in the past year (AOR 12.73, p = 0.002) had increased risk for depression.
CONCLUSION: The prevalence of anxiety was 12.0% while depression was 7.8% in our cohort. AD renders a significant burden on mental health and QOL with a higher impact on those with more severe disease. The use of screening tools such as HADS and DLQI for assessment of mental health and QOL should be considered to address the multidimensional burden of AD.
MATERIALS AND METHODS: A retrospective cross-sectional study of all severe COVID-19 patients who received CP treatment from 1st August 2020 until 31st December 2020 was conducted. Clinical outcomes were compared before and after CP transfusion.
RESULTS: Thirty-four patients were enrolled and received CP transfusion during the study period. The most common presenting complaints were fever (64.7%) and cough (58.8%). Fourteen patients showed improvement in oxygen support after CP transfusion. Several laboratory parameters also improved such as increased lymphocyte count (1.48 vs 1.98, p=0.008) and decreased C-reactive protein levels (28.1 vs 10.6, p=0.004), and these were statistically significant. Median time from symptoms onset to CP transfusion was 6 days (range 1-11) while median time from PCR diagnosis to CP transfusion was 5 days (range 1-11). One patient developed urticaria after CP transfusion and no severe adverse events were observed. Two of our patients passed away due to secondary causes.
CONCLUSION: This study showed CP treatment was well tolerated and could potentially prevent progression of COVID-19 to a severe disease if administered early during the viraemic phase. Further evaluation with randomized control trial should be conducted to help ascertain the optimal dose and effectiveness of CP treatment, in correlation with the IgG titer of the donated CP.
METHODS: The questionnaire was developed in two stages: item development and scale development. Two forms of validity evidence were applied, which were content validity index (CVI) and face validity index (FVI), to estimate the content validity, response process and internal structure of the tool. This cross-sectional study was conducted among premarital young adults in Kota Bharu, Kelantan. The questionnaire assessed perceptions and attitudes toward IPV on six related components, which were its forms, causes, impacts, supports, acceptance and willingness to disclose.
RESULTS: CVI values for both perceptions and attitudes domains were more than 0.83. Five of the components have few items with low agreement by experts, hence those items were dropped. FVI values for the six domains among premarital young adults were at least 0.83, thus all these items were retained. The final result of development of this questionnaire were 64 items for perceptions and 23 items for attitudes, with five-Likert scale response option.
CONCLUSION: The newly developed tool, named as MYPAIPVQ, is valid based on content validity and face validity to assess perceptions and attitudes toward intimate partner violence among premarital young adults. Before it can be used, further validation studies should be conducted to determine its psychometric properties.
METHODS: DLBCL patients at HPP who underwent 18F-FDG PET/CT and BMB were recruited between November 2016 to February 2018. Two reviewers, blinded to the BMB results, evaluated the 18F-FDG PET/CT scans to identify and characterize BMI. The diagnostic performance of 18F-FDG PET/CT was calculated using the BMB histopathological evaluation as the reference standard.
RESULTS: A total of 21 DLBCL patients were enrolled. Seven patients demonstrated BMI on PET/CT (3 with multifocal uptake were concordant with BMB). Fourteen scans were negative for BMI and concordant with BMB. The sensitivity and specificity of 18F-FDG PET/CT scans for detecting BMI is 100% and 77.8%, respectively.
CONCLUSION: 18F-FDG PET/CT is excellent for ruling-out the presence of BMI. A negative 18F-FDG PET/CT scan for BMI can preclude the need for BMB in certain cases. Although 18F-FDG PET/CT can accurately detect BMI in multifocal pattern of infiltration, it cannot fully replace BMB, which is still considered as the gold standard for evaluating BMI in DLBCL.
METHODS: The preliminary version of IPM3P that is used to investigate the perception of Muslim adults with hearing impairment towards Islamic understanding and practice has been tested in this study. The preliminary version of IPM3P consists of three domains (obligation, practice, and difficulty) with 59 items in total. Four phases of validity and reliability testing involved were: i) Content validation, ii) Pretesting, face validity and proofreading, iii) Pilot study, and iv) Psychometric evaluation.
RESULTS: The final version of IPM3P consists of 36 items. The findings from the present study suggest that the final version of IPM3P has excellent psychometric properties manifested by: i) good content validity, ii) excellently pretested, iii) good face validity, iv) good construct validity shown by principal component analysis and convergent validity, and v) good discriminant validity showed by divergent validity.
CONCLUSION: IPM3P shows good potential to be used as a tool in investigating perception of Muslim adults towards Islamic understanding and practice.
METHODS: This study involved forward and back translation method. The translated questionnaire was then pretested and piloted among 10 parents and 50 participants, respectively. The procedure was repeated using the same questionnaire to evaluate the test-retest reliability.
RESULTS: The ERC-Malay (ERC-M) has excellent qualitative and quantitative measurements in both item-level content validation index (I-CVI) and scale-level content validation index (S-CVI). In addition, the ERC-M demonstrated good internal consistency from Cronbach's alpha and test-retest reliability based on the Intraclass Correlation Coefficient (ICC) in all domains.
CONCLUSION: ERC-M can potentially be used as a tool to evaluate emotion for the population with emotional dysregulation issue, such as autism spectrum disorder.
