    The incidence of West syndrome (WS) was determined by a search of reports of electroencephalograms (EEG) recorded in 1998 and 1999 in all public hospitals in Singapore. Amongst records of patients born in 1998, nine were found with EEG features of hypsarrhythmia or modified hypsarrhythmia with onset of seizures between January 1,1998 and December 31, 1999. The medical records of these patients were reviewed. The population of children born in 1998 was 43,664. In 1998 and 1999, 67% of all hospital admissions for patients 2 years or younger in Singapore were in public hospitals. The cumulative incidence of WS in Singapore corrected for the percentage of hospital admissions to public hospitals was 3.1/10,000 live births. The corrected cumulative incidences in Chinese, Malays and Indians were 2.7, 3.1 and 3.3 per 10,000, respectively. Three cases were idiopathic; three were due to congenital structural lesions of the brain; one each had periventricular leucomalacia, intracranial hemorrhage and severe intrauterine growth retardation. None of the patients were normal at follow up. The three patients with idiopathic WS had mild global developmental delay and the other six cases had cerebral palsy and severe mental retardation. With the best modern medical treatment, possibly only two of the nine cases of WS may have been prevented.

    Ventriculoperitoneal shunt (VPS) is a common procedure in neurosurgery for Cerebrospinal Fluid (CSF) diversion. It is associated with various complication. One of the rarer complications is migration of the shunt catheter. The incidence is higher in the paediatric population, up to 71.2% compared to adults 28.8%. We present a case of a 1 year 4 months old boy post TB meningitis with intrathoracic shunt migration 2 months after implantation of VPS. The child presented with upward gaze palsy, on and off productive cough and fever. He had a ventriculoperitoneal shunt inserted 2 months before, when he was diagnosed and treated for TB meningitis. Radiological imaging revealed the distal catheter tip was at the right lung with pneumothorax. The shunt was removed and after confirming that there is no active infection, a new ventriculoperitoneal shunt was reinserted.

    Accumulation of oxidized nucleic acids causes genomic instability leading to senescence, apoptosis, and tumorigenesis. Phytoagents are known to reduce the risk of cancer development; whether such effects are through regulating the extent of nucleic acid oxidation remains unclear. Here, we outlined the role of reactive oxygen species in nucleic acid oxidation as a driving force in cancer progression. The consequential relationship between genome instability and cancer progression highlights the importance of modulation of cellular redox level in cancer management. Current epidemiological and experimental evidence demonstrate the effects and modes of action of phytoagents in nucleic acid oxidation and provide rationales for the use of phytoagents as chemopreventive or therapeutic agents. Vitamins and various phytoagents antagonize carcinogen-triggered oxidative stress by scavenging free radicals and/or activating endogenous defence systems such as Nrf2-regulated antioxidant genes or pathways. Moreover, metal ion chelation by phytoagents helps to attenuate oxidative DNA damage caused by transition metal ions. Besides, the prooxidant effects of some phytoagents pose selective cytotoxicity on cancer cells and shed light on a new strategy of cancer therapy. The "double-edged sword" role of phytoagents as redox regulators in nucleic acid oxidation and their possible roles in cancer prevention or therapy are discussed in this review.

    AIM: To determine the occurrence, factors and outcome of missed nursing care from the perspective of Malaysian nurses.

    BACKGROUND: Missed nursing care is an important issue in the global health care sector. However, little is known on the extent of missed nursing care in the Malaysian context and its contributing factors.

    METHODS: A cross-sectional design was adopted for data collection using the MISSCARE Survey instrument. Participants comprised 364 nurses from medical and surgical wards of a large teaching hospital. Data were analysed using descriptive, binomial logistic and hierarchical regression analyses.

    RESULTS: The overall occurrence of missed nursing care was 1.88 (on a scale of 1.00-5.00), which differed across 24 nursing care elements. Basic nursing care and communication-related care were the most frequently missed elements. Types of ward and labour resources were identified as contributing factors to missed nursing care (p  .05).

    CONCLUSION: The occurrence of missed nursing care was noted to be low.

    IMPLICATIONS FOR NURSING MANAGEMENT: Practical strategies such as an acuity-based staffing system, close monitoring of rendered care and strengthening of teamwork are recommended to minimize missed nursing care.

    Cell entry of influenza A virus (IAV) was reported to be promoted by epidermal growth factor receptor (EGFR). On the other hand, binding of heparin-binding EGF-like growth factor (HB-EGF) to EGFR leads to internalisation and degradation of the receptors. This study aimed to testify whether or not HB-EGF-induced downregulation of EGFR could attenuate IAV cell entry and subsequently diminish the infection. Immunoblotting and plaque assay revealed that HB-EGF-induced degradation of EGFR led to reduction of viral matrix 1 protein level and suppressed virion production. In addition, immunoblotting and imaging flow cytometric analysis demonstrated that IAV-induced phosphorylation of STAT1 and its localisation to nucleus in the early stage of infection were inhibited by HB-EGF treatment. This suggested the potential of HB-EGF in modulating uncontrolled and exaggerated inflammatory response caused by IAV infection. Together these findings attest the potential of HB-EGF mediated endocytosis and degradation of EGFR as a novel anti-IAV strategy.

    Background: Porcupine dates are phytobezoar stones that are used in Traditional Chinese Medicine (TCM) treatments against cancer, postsurgical recovery, dengue fever, etc. The medicinal values have not been scientifically investigated due to the availability and high pricing of the dates.

    Objectives: This paper represents the first report on the phytochemical content, in vitro antioxidant and intracellular reactive oxygen species (ROS)/reactive nitrogen species (RNS) scavenging properties of the extracts of three porcupine dates: grassy date (GD), black date (BD), and powdery date (PD).

    Materials and Methods: Dried samples were extracted with methanol and lyophilized. Samples were screened for phytochemical constituents, in vitro antioxidant assays based on total phenolic content (TPC), free radical scavenging, and ferric reducing power (FRP) as well as intracellular ROS and RNS scavenging properties.

    Results: Phytochemical screening and total tannins assay revealed that tannins, cardiac glycosides, and terpenoids were found in all porcupine dates with tannins forming the major portion of the TPC. In comparison to GD, BD and PD were found to contain significantly high TPC, radical scavenging activity, and FRP. At 200 μg/ml, BD and PD remarkably scavenged 2, 2-azobis (2-amidinopropane) dihydrochloride-induced ROS in RAW264.7 cells and significantly reduced nitric oxide in lipopolysaccharide-stimulated cells.

    Conclusion: Overall, BD and PD exhibited promising in vitro antioxidant as well as intracellular ROS/RNS scavenging properties.

    SUMMARY: Tannins, cardiac glycoside, and terpenoids were found in all three types of porcupine dates with tannins being the major compoundsAntioxidant contents and properties of three dates were in the order black date (BD) > powdery date (PD) > grassy dateBD and PD extracts showed significant intracellular reactive oxygen species and reactive nitrogen species scavenging properties. Abbreviations Used: TCM: Traditional Chinese Medicine, BD: Black date, GD: Grassy date, PD: Powdery date, TPC: Total phenolic content, FRS: Free radical scavenging, FRP: Ferric reducing power, NO: Nitric oxide, ROS: Reactive oxygen species, RNS: Reactive nitrogen species, GAE: Gallic acid equivalent, AAE: Ascorbic acid equivalent, PVPP: Polyvinylpolypyrrolidone, DCFH-DA: Dichloro-dihydro-fluorescein diacetate, AAPH: 2, 2-azobis (2-amidinopropane) dihydrochloride, LPS: Lipopolysaccharide.

    P-glycoprotein (PgP) is the most extensively studied ATP-binding cassette (ABC) coded by MDR1 gene. To date, 29 single nucleotide polymorphisms (SNPs) have been identified; but only SNP C3435T has been correlated with intestinal PgP expression levels and shown to influence the absorption of orally taken drugs that are PgP substrates. Individuals homozygous for the T allele have more than fourfold lower PgP expression compared with C/C individuals. We developed a one step primer based allele specific PCR method to detect SNP at C3435T to investigate the distribution of this genotype in the local population.

    Poor adherence is a significant nursing and public health concern because it affects patients' quality of life. It compounds the disease burden of the growing coronary heart disease population. Promoting optimal patient adherence to cardiac-health enhancing recommendations by healthcare providers can reduce mortality and morbidity risk after acute coronary syndrome (ACS).

    This survey covered male Singapore citizens born in 1974 who were medically screened at the age of 18 years before enlistment for compulsory military service. Suspected epileptics were referred to government hospitals for further management. Out of 20,542 men, there were 121 epileptics, giving a cumulative incidence of 5 per 1000 by age 18 years. We had information on 106 (87%) of these individuals and were able to interview them and review their hospital records. Seventy-three of the 106 (69%) epileptics had generalised seizures while 14 (13%) had refractory seizures. There was no statistically significant racial bias amongst these epileptics. Unprovoked afebrile seizures occurred early in these patients, half of whom had seizures onset before 7 years of age. Nine refractory epileptics had a history of febrile seizures, 4 of which were complex febrile seizures. Magnetic resonance imaging identified mesial temporal sclerosis in 2 patients and a hypothalamic lesion in 1 patient. Computed tomographic scans revealed focal cortical atrophy in 2 patients. Nine other patients had normal imaging studies. Nine out of 14 (64%) patients with refractory epilepsy had partial seizures; 4 (29%) had generalised seizures and 1 (7%) was unclassified. This is in contrast to the distribution of the entire cohort of epileptics studied. Two out of 9 patients with refractory partial seizures (gelastic epilepsy and mesial temporal sclerosis) had undergone surgery while 6 of the other 7 patients refused to consider surgery.

    Drug resistance remains a severe problem in most chemotherapy regimes. Recently, it has been suggested that cancer cell-derived extracellular vesicles (EVs) could mediate drug resistance. In this study, the role of EVs in mediating the response of oral squamous cell carcinoma (OSCC) cells to cisplatin was investigated. We isolated and characterized EVs from OSCC cell lines showing differential sensitivities to cisplatin. Increased EV production was observed in both de novo (H314) and adaptive (H103/cisD2) resistant lines compared to sensitive H103 cells. The protein profiles of these EVs were then analyzed. Differences in the proteome of EVs secreted by H103 and H103/cisD2 indicated that adaptation to cisplatin treatment caused significant changes in the secreted nanovesicles. Intriguingly, both resistant H103/cisD2 and H314 cells shared a highly similar EV protein profile including downregulation of the metal ion transporter, ATP1B3, in the EVs implicating altered drug delivery. ICP-MS analysis revealed that less cisplatin accumulated in the resistant cells, but higher levels were detected in their EVs. Therefore, we inhibited EV secretion from the cells using a proton pump inhibitor and observed an increased drug sensitivity in cisplatin-resistant H314 cells. This finding suggests that control of EV secretion could be a potential strategy to enhance the efficacy of cancer treatment.

    BACKGROUND: Oral cancer is the sixth most common cancer worldwide and 90% of oral malignancies are caused by oral squamous cell carcinoma (OSCC). Curcumin, a phytocompound derived from turmeric (Curcuma longa) was observed to have anti-cancer activity which can be developed as an alternative treatment option for OSCC. However, OSCC cells with various clinical-pathological features respond differentially to curcumin treatment.

    HYPOTHESIS: Intracellular copper levels have been reported to correlate with tumor pathogenesis and affect the sensitivity of cancer cells to cytotoxic chemotherapy. We hypothesized that intracellular copper levels may affect the sensitivity of oral cancer cells to curcumin.

    METHODS: We analysed the correlation between intracellular copper levels and response to curcumin treatment in a panel of OSCC cell lines derived from oral cancer patients. Exogenous copper was supplemented in curcumin insensitive cell lines to observe the effect of copper on curcumin-mediated inhibition of cell viability and migration, as well as induction of oxidative stress and apoptosis. Protein markers of cell migration and oxidative stress were also analysed using Western blotting.

    RESULTS: Concentrations of curcumin which inhibited 50% OSCC cell viability (IC50) was reduced up to 5 times in the presence of 250 µM copper. Increased copper level in curcumin-treated OSCC cells was accompanied by the induction of intracellular ROS and increased level of Nrf2 which regulates oxidative stress responses in cells. Supplemental copper also inhibited migration of curcumin-treated cells with enhanced level of E-cadherin and decreased vimentin, indications of suppressed epithelial-mesenchymal transition. Early apoptosis was observed in combined treatment but not in treatment with curcumin or copper alone.

    CONCLUSION: Supplement of copper significantly enhanced the inhibitory effect of curcumin treatment on migration and viability of oral cancer cells. Together, these findings provide molecular insight into the role of copper in overcoming insensitivity of oral cancer cells to curcumin treatment, suggesting a new strategy for cancer therapy.

    AIM: To investigate semantic equivalence between two translated versions of the heart quality of life (HeartQoL) questionnaire produced by the forward-backward and dual-panel methods.

    METHODS: The forward-backward and dual-panel versions of HeartQoL were self-administered among 60 participants who met the inclusion criteria of being a native Bahasa Malaysia-speaking Malay, aged 18 and older, having an indexed diagnosis of ischaemic heart disease and being cognitively fit. The administration sequence of the two versions was randomized. Additionally, three sociolinguists, who were blinded to translation processes and survey findings, rated the translated versions against the source version on three aspects of semantic equivalence.

    RESULTS: Textual content in both translated versions was considerably similar (n = 9/14 items, ≈64%). The overall results from weighted kappa, raw agreement, intraclass correlations, and Wilcoxon signed-rank as well as experts' ratings were confirmative of semantic equivalence between the forward-backward and dual-panel versions of the HeartQoL. However, some mixed findings were indicative of potential gaps in both translated versions against the source version.

    CONCLUSION: Both the forward-backward and dual-panel methods produced semantically equivalent versions of HeartQoL; but translation alone is insufficient to narrow the subtle gaps caused by differences in culture and linguistic style.

    L-asparaginase from endophytic Fusarium proliferatum (isolate CCH, GenBank accession no. MK685139) isolated from the medicinal plant Cymbopogon citratus (Lemon grass), was optimized for its L-asparaginase production and its subsequent cytotoxicity towards Jurkat E6 cell line. The following factors were optimized; carbon source and concentration, nitrogen source and concentration, incubation period, temperature, pH and agitation rate. Optimization of L-asparaginase production was performed using One-Factor-At-A-Time (OFAT) and Response surface methodology (RSM) model. The cytotoxicity of the crude enzyme from isolate CCH was tested on leukemic Jurkat E6 cell line. The optimization exercise revealed that glucose concentration, nitrogen source, L-asparagine concentration and temperature influenced the L-asparaginase production of CCH. The optimum condition suggested using OFAT and RSM results were consistent. As such, the recommended conditions were 0.20% of glucose, 0.99% of L-asparagine and 5.34 days incubation at 30.50 °C. The L-asparaginase production of CCH increased from 16.75 ± 0.76 IU/mL to 22.42 ± 0.20 IU/mL after optimization. The cytotoxicity of the crude enzyme on leukemic Jurkat cell line recorded IC50 value at 33.89 ± 2.63% v/v. To conclude, the enzyme extract produced from Fusarium proliferatum under optimized conditions is a potential alternative resource for L-asparaginase.

    The benefits of isometric strengthening exercises (ISEs) are compromised when patient teaching on ISEs is delayed and/or ineffectively delivered due to healthcare resources constraint, especially when health resources are stretched, as occurred during the COVID-19 pandemic. This study aims to examine the effect of a video-assisted ISE program on pain and muscle strength of patients following surgical stabilization of lower limb fracture. A quasi-experimental study with repeated measures was employed. Primary study outcomes were assessed using the Brief Pain Inventory and Manual Muscle Test. Effects over time were analyzed using generalized estimating equations. In comparison with usual care group (n = 32), the intervention group (n = 33) showed better pain reduction over time (p < .001, effect size [ES] = 0.39-1.77) and muscle strength preservation (p < .05; ES = 0.8-0.9). Patient acceptance of the intervention was favorable. Integration of video clips into patient teaching on ISEs is potentially beneficial in managing pain and muscle strength; it can be easily deployed to aid early ISE initiation.

    L-asparaginase is an enzyme commonly used to treat acute lymphoblastic leukemia. Commercialized bacterial L-asparaginase has been reported to cause several life-threatening complications during treatment, hence the need to seek alternative sources of L-asparaginase. In this study, the novelty of upstream and downstream bioprocessing of L-asparaginase from a fungal endophyte, Colletotrichum gloeosporioides, and the cytotoxicity evaluation was demonstrated. Six variables (carbon source and concentration, nitrogen source and concentration, incubation period, temperature, pH and agitation rate) known to influence L-asparaginase production were studied using One-Factor-At-A-Time (OFAT) approach, with four significant variables further optimized using Response Surface Methodology (RSM). The crude extract produced using optimized condition was purified, characterized and examined for its anticancer effect. Purification of fungal L-asparaginase was performed via ultrafiltration and size exclusion chromatography, which are less common techniques. The protein profile and monomeric weight of L-asparaginase were determined using SDS-PAGE and Western blot. Cytotoxicity of purified L-asparaginase on leukemic Jurkat E6 and oral carcinoma cells were studied using MTS assay for 24 h and 48 h. OFAT results from optimization showed that glucose and L-asparagine concentrations, incubation period and temperature, were significant factors affecting L-asparaginase production by C. gloeosporioides. RSM analysis further evidence the significant interaction between glucose and L-asparagine concentrations in inducing L-asparaginase production. Purified L-asparaginase was profiled with specific activity of 255.02 IU/mg protein, purification fold of 6.12, and 34.63% of enzyme recovery. SDS and Western blot revealed that the purified L-asparaginase might be a tetramer with monomeric units of 25 kDa. Purified L-asparaginase was discovered to be more efficient against Jurkat leukemic cells than against H103 oral carcinoma cells, as lower IC50 value was observed for Jurkat cell lines (46 .36 ± 1.52 µg/mL for Jurkat and 125.56 ± 7.28 µg/mL for H103). In short, purified L-asparaginase derived from endophytic C. gloeosporioides showed high purity and significant anticancer effect toward cancer cells. This study therefore demonstrated the potential of fungal L-asparaginase as alternative chemotherapy drug in the future.

    BACKGROUND: The cross-cultural adaptation of questionnaires has tenuous theoretical underpinnings that limit the rigor of data collection and the meaningful analysis of cognitive interview data. An adaptation of existing models of equivalence and cognition provides structure to the comprehensive investigation of various equivalence types in enhancing the validity of translated questionnaires.

    PURPOSE: In this study, a framework comprising equivalence and cognition models was used to assess and finalize the Heart Quality-of-Life (HeartQoL)-Bahasa Malaysia (BM) questionnaire, which was derived from both forward-backward (FB) and dual-panel (DP) translation methods.

    METHODS: Investigation and finalization of two initial versions of the questionnaire were conducted based on findings from an expert assessment (n = 3 sociolinguists blinded to translation methods) and cognitive interviews with purposively sampled patients (FB: n = 11; DP: n = 11). The equivalence model of Herdman et al. and the question-and-answer model of Collins were adapted to form a "cognition-and-equivalence" model to guide data collection and analysis through modified cognitive interviews. The final HeartQoL-BM was completed by 373 patients with ischemic heart disease from two medical centers, and the data were analyzed using confirmatory factor analysis to assess the evidence of equivalence.

    RESULTS: Findings from the expert assessment and cognitive interview showed the existence of semantic and item equivalence on almost all of the FB and DP items, identified some subtle potential equivalence gaps, and guided the process of item finalization. Confirmatory factor analysis, including tests of factorial invariance on the final two-factor model of HeartQoL-BM, confirmed conceptual, item, measurement, and operational equivalence, which supports functional equivalence.

    CONCLUSIONS: The potential use of the cognition-and-equivalence model for modified cognitive interviewing and the application of the six equivalence types of Herdman et al. were supported by the HeartQoL-BM showing functional equivalence with its source. HeartQoL-BM is a potentially valid measure of health-related quality of life for patients with ischemic heart disease independent of conditions such as angina, myocardial infarction, and heart failure.

    BACKGROUND: The popular wrist-worn wearables recording a variety of health metrics such as blood pressure (BP) in real time could play a potential role to advance precision medicine, but these devices are often insufficiently validated for their performance to enhance confidence in its use across diverse populations. The accuracy of BP-enabled smartwatch is assessed among the multi-ethnic Malaysians, and findings is discussed in comparison with conventional automated upper-arm BP device.

    METHODS: Validation procedures followed the guidelines by the Association for the Advancement of Medical Instrumentation/European Society of Hypertension/International Organization for Standardization (AAMI/ESH/ISO) Universal Standard (ISO 81060-2:2018). Quota sampling was employed to obtain eligible patients with normal and abnormal BP as per guideline. The measurements of BP were taken at wrist using HUAWEI WATCH D (test BP); and the readings were assessed against reference BP by the mercury sphygmomanometer. Agreement statistics and linear regression analyses were performed.

    RESULTS: BP measurements (234 data pairs) from 78 patients that fulfilled AAMI/ESH/ISO protocol were analyzed. The BP readings taken by the HUAWEI WATCH D were comparable to reference BP by sphygmomanometer based on 1) Criterion 1: systolic blood pressure (SBP) = -0.034 (SD 5.24) and diastolic blood pressure (DBP) = -0.65 (SD 4.66) mm Hg; and 2) Criterion 2: SBPs = -0.034 (SD 4.18) and DBPs = -0.65 (SD 3.94) mm Hg. Factors of sociodemographic characteristics, anthropometric measurements, cardiovascular comorbidities, and wrist hair density were not significantly associated with the mean BP differences.

    CONCLUSIONS: HUAWEI WATCH D fulfilled criteria 1 and 2 of the AAMI/ESH/ISO Universal Standard (ISO 81060-2:2018) guidelines. It can be recommended for clinical use across a wider population. The rich data from real-time BP measurements in concurrent with other health-related parameters recorded by the smartwatch wearable offer opportunities to drive precision medicine in tackling therapeutic inertia by personalizing BP control regimen.

    1. A retrospective study was conducted to explore the importance of CYP2C9 genotyping for the initiation and maintenance therapy of warfarin in clinical practice. A total of 191 patients on warfarin therapy in a local hospital were recruited after written informed consent. Their medical records were reviewed and no intervention of warfarin dose was performed. 2. A total of 5 ml of blood were taken from each subject for DNA extraction and identification of 1, 2, 3 and 4 CYP2C9 alleles, using a nested-allele-specific-multiplex-polymerase chain reaction (PCR). Half the patients were Malays and the remaining were Chinese. 3. Two genotypes were detected; 93.2% had CYP2C9 1/1 and 6.8% were CYP2C9 1/3. Warfarin doses were higher in patients with CYP2C91/1. Patients with the 1/3 genotype experienced a higher rate of serious and life-threatening bleeding; 15.4 versus 6.2 per 100 patients per 6 months. 4. The observation clearly highlights the inadequacy of the current dosing regimens and the need to move toward a more individualized approach to warfarin therapy. Prospective clinical studies are now being conducted to assess dosing algorithms that incorporate the contribution of the genotype to allow the individualization of warfarin dose.

    OBJECTIVES: Heart Quality of Life (HeartQoL) is a new "hybrid" developed from the MacNew and two condition-specific questionnaires measuring health-related quality of life (HRQoL) in patients with ischemic heart disease (IHD). This study investigates test-retest reliability of HeartQoL (English version) according to international criteria (e.g., COSMIN, GRRAS). Findings on HeartQoL are compared to the published data on MacNew in view that both serve as the core IHD-specific HRQoL instrument.

    METHODS: Out of 105 patients with IHD, 76 completed self-administration of HeartQoL at the clinic followed by at home within a 2-week interval. In retest, patients responded using non-interview methods (phone messaging, email, fax, and post). Phone interviewing was reserved for non-respondents to reminder.

    RESULTS: Reliability of HeartQoL was good (intraclass correlation coefficients = 0.78-0.82), was supported in the Bland-Altman plot, and was comparable to five studies on MacNew of similar retest interval (MacNew-English = 0.70-0.75; translated MacNew = 0.72-0.91). Applicability of its standard error of measurement (0.20-0.25) and smallest detectable change (0.55-0.70) will depend on availability of normative data in future.

    CONCLUSION: The reliability of HeartQoL is comparable to its parent instrument, the MacNew. The HeartQoL is a potentially reliable core IHD-specific HRQoL instrument in measuring group change.
