Food contamination is a crucial health problem as it could result in food-borne illness. This research aimed to evaluate the microbiological quality of ready-to-eat (RTE) fried rice dishes sold at different type of food premises in Kuantan city, Pahang. Total Plate Count (TPC), Staphylococcus aureus, Bacillus cereus and Aeromonas spp. bacteria were used as microbiological contamination indicators. About 52 samples were collected stratified randomly from four types of food premises (restaurant, cafeteria, food stall and night market) where about 13 samples were respectively collected from each type of the food premises. The results showed that TPC had medium mean count (6.30x105±1.47x105 cfu/g), S. aureus and B. cereus had high mean counts (7.70x104±2.22x105 cfu/g and 3.85x105±1.67x106 cfu/g respectively), while Aeromonas spp. had medium mean count (7.13x104±2.42x105 cfu/g). The mean counts of TPC in the samples collected from cafeteria were highest compare to other food premises.

A real-time quantitative polymerase chain reaction (qPCR) was developed for detection and discrimination of Mycobacterium tuberculosis (H37Rv and H37Ra) and M. bovis bacillus Calmette-Guérin (BCG) of the Mycobacterium tuberculosis complex (MTBC) from mycobacterial other than tuberculosis (MOTT). It was based on the melting curve (Tm) analysis of the gyrB gene using SYBR(®) Green I detection dye and the LightCycler 1.5 system. The optimal conditions for the assay were 0.25 μmol/L of primers with 3.1 mmol/L of MgCl(2) and 45 cycles of amplification. For M. tuberculosis (H37Rv and H37Ra) and M. bovis BCG of the MTBC, we detected the crossing points (Cp) at cycles of 16.96 ± 0.07, 18.02 ± 0.14, and 18.62 ± 0.09, respectively, while the Tm values were 90.19 ± 0.06 °C, 90.27 ± 0.09 °C, and 89.81 ± 0.04 °C, respectively. The assay was sensitive and rapid with a detection limit of 10 pg of the DNA template within 35 min. In this study, the Tm analysis of the qPCR assay was applied for the detection and discrimination of MTBC from MOTT.

To review the long term outcome of Uvulopalatopharyngoplasty (UPPP) for obstructive sleep apnoea syndrome in a tertiary referral centre. 38 records were traced where UPPP was done from July 2000 to December 2007. 14 patients were followed up for one to seven years where the Epworth sleepiness scale was scored, long term side effects documented and post operative muller's manoeuvre done. Success of UPPP is defined as a reduction in apnoea hypopnea index (AHI) more than 50%. Sixty percent (60%) were successfully treated with UPPP in the long term. Mean ESS was significantly reduced from 12 +/- 6 to 7 +/- 4. 11 out of 14 patients (78.5%) were reported to develop long term side effects of UPPP, the highest being velopharyngeal insufficiency (42.8%). In conclusion, UPPP is effective in improving symptoms of OSA in the long term. However, in view of its side effects, uvula preserving surgery should be considered as a surgical option.

PMID: 31732294 DOI: 10.1016/j.jvoice.2019.09.017

OBJECTIVE: This study compared the voice outcomes of selected patients with unilateral vocal fold palsy (UVFP) who underwent either nonselective laryngeal reinnervation (LR) or Type 1 thyroplasty (thyroplasty) in a Malaysian tertiary centre using multidimensional voice assessments.
PARTICIPANTS: The study included 16 patients with UVFP who underwent either LR (9 patients) or thyroplasty (7 patients) between 2015 and 2018 who fulfilled the inclusion criteria.
MAIN OUTCOME MEASURES: The outcomes were measured subjectively and objectively with: (1) voice handicap index-10 (VHI-10- Malay version); (2) auditory perceptual evaluation using the breathiness component of Grade, Roughness, Breathiness, Asthenia, Strain scale; (3) maximum phonation time (MPT); and (4) acoustic analysis (jitter%, shimmer%, and NHR) using OperaVOXTM. The outcomes were measured at baseline, 6 and 12-months postoperative. The comparison of outcomes between pre and postoperative of each group was evaluated using one-way ANOVA test. Mann-Whitney test was used to compare the outcomes between the two groups.
RESULTS: Comparison of each group at different time points showed significant improvement of VHI-10 and MPT of LR group between baseline and 12 months (P ≤ 0.05) whereas, the improvement in thyroplasty group was observed at all time points (P ≤ 0.05). When comparing between the two groups at 12 months, the VHI-10 and MPT was significantly better in the LR group than thyroplasty group with P = 0.004 and P = 0.001 respectively. Other outcome measures did not reveal significant difference between the two groups.
CONCLUSION: This observational study showed that LR may be better than thyroplasty in improving VHI-10 and MPT in selected patients with UVFP.

Neuropathy is a problem often suffered by patients with diabetes mellitus. Types of neuropathy that occur are peripheral neuropathy and autonomic neuropathy. This cross sectional study was conducted to determine the association between duration of diabetes and loss of protective sensation and the association between imbalance and loss of protective sensation among Malay women with diabetes mellitus. Eighty one Malay women with diabetes mellitus, aged 20 to 60 years from three clinics in Hulu Langat District participated in this study. Socio-demographic information were obtained from respondent using a questionnaire. Foot sensory evaluation was conducted using Semmes-Weinstein Monofilament
grade 5.07. Assessment of balance was done using Timed One-leg Stance. Chi-squared test was used to determine the association between the two variables. Result showed that 56.8% of respondent had loss of protective sensation on at least one foot. While, 17.3% had imbalance while eyes were open and 60.5% experienced imbalance while eyes were closed. However, there was no significant correlation (p<0.05) between imbalance while eyes opened [χ2=3.27, p=0.07] and while eyes close [χ2=0.29, p=0.59]) with loss of protective sensation in at least one foot. Similar result were obtained between duration of diabetes and the loss of protective sensation. (χ2=3.27, p=0.20). Although there was no association between these factors, a screening program should start early to ensure early problems are identified before more severe complications occur.

The performance of the defect prediction model by using balanced and imbalanced datasets makes a big impact on the discovery of future defects. Current resampling techniques only address the imbalanced datasets without taking into consideration redundancy and noise inherent to the imbalanced datasets. To address the imbalance issue, we propose Kernel Crossover Oversampling (KCO), an oversampling technique based on kernel analysis and crossover interpolation. Specifically, the proposed technique aims to generate balanced datasets by increasing data diversity in order to reduce redundancy and noise. KCO first represents multidimensional features into two-dimensional features by employing Kernel Principal Component Analysis (KPCA). KCO then divides the plotted data distribution by deploying spectral clustering to select the best region for interpolation. Lastly, KCO generates the new defect data by interpolating different data templates within the selected data clusters. According to the prediction evaluation conducted, KCO consistently produced F-scores ranging from 21% to 63% across six datasets, on average. According to the experimental results presented in this study, KCO provides more effective prediction performance than other baseline techniques. The experimental results show that KCO within project and cross project predictions especially consistently achieve higher performance of F-score results.
