Background & Objective: Modulation of cortical excitability by low frequency repetitive transcranial
magnetic stimulation (rTMS) has demonstrated therapeutic use in epilepsy. This study aimed to evaluate
the efficacy of low-frequency rTMS on refractory epilepsy in a group of Malaysian subjects. Methods:
Nine patients with refractory epilepsy completed the study. All patients received 10 sessions of 1Hz
rTMS (1000 pulses per session) at 90% of resting motor threshold. Outcome measures included seizure
frequency, Symptom Checklist-90 (SCL-90), Beck Depression Inventory II (BDI II) and Quality of
Life in Epilepsy-31 (QOLIE-31). Responders were defined as having ≥ 50% seizure reduction. Results:
The mean age was 33.8 years (SD 11.7), with 4 male. Three patients had mesial temporal sclerosis
(MTS); 4 with focal cortical dysplasia (FCD) and two lesion-negative. Three patients achieved >50%
seizure reduction at 8 weeks post-treatment, with 2 of them had improvement in the number of IED.
All of the responders had FCD. The responders were younger (mean 24.7 vs. 38.3 years old), had
shorter duration of illness (mean 15.7 vs. 30.5 years) and had less frequent seizure frequency prior to
treatment (mean 5.5 vs. 10.8 attacks per week), as compared to the non-responders. Six patients had
improvement in BDI-II scores, two in QOLIE-31 and four in SCL-90 post treatment, irrespective of
seizure control. The mean scores in BDI-II improved significantly with treatment (p<0.01).
Conclusion: rTMS is a potentially promising treatment for epilepsy, esp

INTRODUCTIONThis study investigated the effect of an access-enhanced intervention on hypertension screening and management, as well as on health behaviours among newly diagnosed hypertensives, in a multi-ethnic low socioeconomic status (SES) community. Factors associated with hypertension screening, treatment, and control in the community were also determined.
MATERIALS AND METHODSThe study involved all residents aged ≥40 years in 2 public rental housing precincts (low SES), between 2009 and 2011, who were followed-up prospectively for 1 year after a 6-month community-based intervention comprising a 3-month access-enhanced screening component and a 3-month follow-up (outreach) component. Blood pressure was measured at baseline and follow-up. Multivariate Cox regression determined predictors of hypertension management at follow-up.
RESULTSThe follow-up rate was 80.9% (467/577). At baseline, 60.4% (282/467) were hypertensive; 53.5% (151/282) were untreated; 54.2% (71/131) uncontrolled. One year later, postintervention, 51.6% (78/151) of untreated hypertensives were treated; combined with treated hypertensives previously uncontrolled, 53.0% (79/149) achieved control. Older age independently predicted treatment (adjusted relative risk, aRR = 1.98, CI, 1.08 to 3.65); majority ethnicity (aRR = 1.76, CI, 1.05 to 2.96), employment (aRR = 1.85, CI, 1.26 to 2.80) and newly treated hypertension (aRR=1.52, CI, 1.01 to 2.32) predicted control. A total of 52.4% (97/185) were irregularly screened at baseline; at follow-up 61.9% (60/97) were regularly screened. Cost and misperceptions were common barriers to screening and treatment. Newly diagnosed hypertensives were also less likely to go for additional cardiovascular screening (aRR = 0.54, CI, 0.29 to 0.99).
CONCLUSIONAn access-enhanced intervention had some success in improving hypertension management within low SES communities; however, it was less successful in improving cardiovascular risk management, especially in encouraging lifestyle changes and additional cardiovascular screening amongst newly diagnosed hypertensives.

INTRODUCTIONHigh workload volumes in a Cytogenetics laboratory can lead to long result turn-around times (TAT). This study aimed to improve laboratory efficiency by adopting Lean Management System initiatives to increase productivity through the elimination of wastes. This study examined if the prerequisite 20-cell analysis was sufficient for a conclusive result or if additional cell workup was necessary to ascertain the presence of a previous chromosome abnormality among cases on follow-up, or when a single abnormal cell was encountered during the analysis to determine the presence of a clone.
MATERIALS AND METHODSThe karyotype results of cases that had additional workup were retrieved from among 8040 bone marrow cases of various haematological disorders performed between June 2003 and June 2008.
RESULTSOf 8040 cases analysed, 2915 cases (36.3%) had additional cell workup. Only 49 cases (1.7%) led to the establishment of a clone. The majority of these cases could have been resolved without the additional workup, especially if fluorescence in situ hybridization (FISH) or polymerase chain reaction (PCR)-based assays had been utilised.
CONCLUSIONThis study shows that the additional workup procedure is redundant. The time saved by discontinuing the workup procedure can be used to analyse other cases, leading to increased laboratory efficiency and a faster TAT without compromise to patient care. The practice of additional workup over and above the 20- cell analysis should be dispensed with as little benefit was derived for the amount of additional manpower expended. FISH or PCR-based assays should be utilised to elucidate a case further.

Purpose:
NUF2 has been implicated in multiple cancers recently, suggesting NUF2 may play a role in the common tumorigenesis process. In this study, we aim to perform comprehensive meta-analysis of NUF2 expression in the cancer types included in the Cancer Genome Atlas (TCGA).
Materials and Methods:
RNA-sequencing data in 31 cancer types in the TCGA data and 11 independent datasets were used to examine NUF2 expression. Silencing NUF2 using targeting shRNAs in hepatocellular carcinoma (HCC) cell lines was used to evaluate NUF2’s role in HCC in vitro and in vivo.
Results:
NUF2 up-regulation is significantly observed in 23 out of the 31 cancer types in the TCGA datasets and validated in 13 major cancer types using 11 independent datasets. NUF2 overexpression was clinically important as high NUF2 was significantly associated with tumor stages in eight different cancers. High NUF2 was also associated with significantly poorer patient overall survival and disease-free survival in eight and six cancers, respectively. We proceeded to validate NUF2 overexpression and its negative association with overall survival at the protein level in an independent cohort of 40 HCC patients. Compared to the non-targeting controls, NUF2 knockdown cells showed significantly reduced ability to grow, migrate into a scratch wound and invade the 8 μm porous membrane in vitro. Moreover, NUF2 knockdown cells also formed significantly smaller tumors than control cells in mouse xenograft assays in vivo.
Conclusion
NUF2 up-regulation is a common feature of many cancers. The prognostic potential and functional impact of NUF2 up-regulation warrant further studies.

INTRODUCTIONHand strength is a good indicator of physical fitness and frailty among the elderly. However, there are no published hand strength references for Malaysians aged > 65 years. This study aimed to establish normative data for hand grip strength (HGS) and key pinch strength (KPS) for Malaysians aged ≥ 60 years, and explore the relationship between hand strength and physical ability.
METHODSHealthy participants aged ≥ 60 years with no neurological conditions were recruited from rural and urban locations in Malaysia. HGS and KPS were measured using hand grip and key pinch dynamometers. Basic demographic data, anthropometric measures, modified Barthel Index scores and results of the Functional Reach Test (FRT), Timed Up and Go (TUG) test and Jebsen-Taylor Hand Function Test (JTHFT) were recorded.
RESULTS362 subjects aged 60-93 years were recruited. The men were significantly stronger than the women in both HGS and KPS (p < 0.001). The hand strength of the study cohort was lower than that of elderly Western populations. Significant correlations were observed between hand strength, and residential area (p < 0.001), FRT (r = 0.236, p = 0.028), TUG (r = -0.227, p = 0.009) and JTHFT (r = -0.927, p < 0.001).
CONCLUSIONThis study established reference ranges for the HGS and KPS of rural and urban elderly Malaysian subpopulations. These will aid the use of hand strength as a screening tool for frailty among elderly persons in Malaysia. Future studies are required to determine the modifiable factors for poor hand strength.

INTRODUCTION:
We aimed to describe the extrapulmonary manifestations of severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) infection, including their frequency, onset with respect to respiratory symptoms, pathogenesis and association with disease severity.
METHODS:
We searched the MEDLINE and Embase databases for SARS-CoV-2-related studies. Meta-analysis, observational studies, case series and case reports published in English or Chinese between 1 January 2020 and 1 May 2020 were included. Reports with only paediatric or obstetric cases were excluded.
RESULTS:
169 articles were included. Early manifestations (preceding respiratory symptoms until Day 6 of onset) included olfactory and gustatory disturbance (self-reported in up to 68% and 85% of cases, respectively), gastrointestinal symptoms (up to 65.9%) and rash (up to 20.4%). From Day 7 onwards, hypercytokinaemia, paralleled multi-organ complications including acute cardiac injury (pooled incidence of 17.7% in 1,412 patients, mostly with severe disease and 17.4% mortality), kidney and liver injury (up to 17% and 33%, respectively) and thrombocytopenia (up to 30%). Hypercoagulability resulted in venous thromboembolic events in up to 31% of all patients. Uncommon disease presentation and complications comprised Guillain-Barré syndrome, rhabdomyolysis, otitis media, meningoencephalitis and spontaneous pneumomediastinum.
CONCLUSION
Although the systemic manifestations of SARS-CoV-2 infection are variegated, they are deeply interwoven by shared mechanisms. Two phases of extrapulmonary disease were identified: (a) an early phase with possible gastrointestinal, ocular and cutaneous involvement; and (b) a late phase characterised by multiorgan dysfunction and clinical deterioration. A clear, multidisciplinary consensus to define and approach thromboinflammation and cytokine release syndrome in SARS-CoV-2 is needed.

INTRODUCTION:
The coronavirus disease 2019 (COVID-19) pandemic has had an unprecedented impact in Asia and has placed significant burden on already stretched healthcare systems. We examined the impact of COVID-19 on the safety attitudes among healthcare workers (HCWs), as well as their associated demographic and occupational factors, and measures of burnout, depression and anxiety.
METHODS:
A cross-sectional survey study utilising snowball sampling was performed involving doctors, nurses and allied health professions from 23 hospitals in Singapore, Malaysia, India and Indonesia between 29 May 2020 and 13 July 2020. This survey collated demographic data and workplace conditions and included three validated questionnaires: the Safety Attitudes Questionnaire (SAQ), Oldenburg Burnout Inventory and Hospital Anxiety and Depression Scale. We performed multivariate mixed-model regression to assess independent associations with the SAQ total percentage agree rate (PAR).
RESULTS:
We obtained 3,163 responses. The SAQ total PARs were found to be 35.7%, 15.0%, 51.0% and 3.3% among the respondents from Singapore, Malaysia, India and Indonesia, respectively. Burnout scores were highest among respondents from Indonesia and lowest among respondents from India (70.9%-85.4% vs. 56.3%-63.6%, respectively). Multivariate analyses revealed that meeting burnout and depression thresholds and shifts lasting ≥12 h were significantly associated with lower SAQ total PAR.
CONCLUSION
Addressing the factors contributing to high burnout and depression and placing strict limits on work hours per shift may contribute significantly towards improving safety culture among HCWs and should remain priorities during the pandemic.
