Knowledge and attitude towards home quarantine instructions and associations with history of Covid-19 infection in Malaysia.

INTRODUCTION: Although COVID-19 has entered the endemic phase, individuals infected with COVID-19 are required to adhere to home quarantine measures. By exploring the public's knowledge and attitude towards recommended home quarantine measures, their readiness in containing potential COVID-19 outbreak can be determined. This study aimed to assess the public knowledge and attitude towards home quarantine instructions and their association with history of COVID-19 infections. METHODS: This was a web-based cross-sectional study conducted among the public in Malaysia between August to October 2022. All Malaysian adults over 18 years of age were included. Knowledge on home quarantine instructions and COVID-19 warning signs were measured using "True," "False," or "I'm not sure", while attitude towards home quarantine instructions was measured using a five-point Likert Scale. The questionnaire was initially constructed in English and then translated into the national language, Bahasa Malaysia. Face and content validation were performed. The internal consistency of the questionnaire was found to be satisfactory. RESULTS: 1,036 respondents were analyzed, comprised mostly of females (743, 71.6%) with a history of COVID-19 (673, 64.9%). In the knowledge domain, more than 80% of the respondents answered 9 out of 11 home quarantine instructions statements correctly. 457 (44.1%) were unaware or unsure about the minimum distance of the infected individual's bed from the rest of the occupants in a shared bedroom. The respondents reported relatively weaker knowledge in identifying uncommon warning signs of COVID-19 deterioration, including anuria (162, 44.5%), ingestion problems (191, 52.5%), and immobility (195, 53.6%). In the attitude domain, more than 90% of respondents answered correctly in 8 out of 9 questions. Respondents with a previous history of COVID-19 infections had better knowledge than COVID-19 infection-naïve individuals towards both home quarantine instructions and COVID-19 warning signs. CONCLUSION: Most respondents had good knowledge and attitude towards home quarantine instructions, with those previously infected with COVID-19 showing greater awareness of uncommon warning signs. However, there was a notable lack of awareness regarding physical distancing within shared rooms, appropriate disinfectant use and mobility limitation within the household. This study highlights the knowledge gaps to be improved in future educational campaigns.

Pregnancy-induced severe hypertriglyceridemia effectively treated with therapeutic plasmapheresis.

INTRODUCTION: Hypertriglyceridemia is associated with significant morbidity during pregnancy. Hypertriglyceridemia-induced pancreatitis (HTGP) is associated with genetically determined dyslipidemia or a secondary condition such as diabetes, alcohol, pregnancy, or medication use. The lack of data on the safety of drugs to be used to decrease triglyceride levels during pregnancy dictates that other strategies must be chosen. PATIENT AND METHODS: We describe a case of a pregnant woman with severe hypertriglyceridemia treated with two different techniques of plasmapheresis (Dual Filtration apheresis and Centrifugal Plasma Separation). RESULTS: The patient could be treated throughout the pregnancy, with good control of the triglycerides, and a healthy baby was born. CONCLUSION: Hypertriglyceridemia is a major issue during pregnancy. The use of plasmapheresis is a safe and efficient tool in that clinical scenario.

Assessing feasibility of a modified same-day test-and-treat model for hepatitis C among rural people who inject drugs.

BACKGROUND: Despite advancements in hepatitis C virus (HCV) treatment, low uptake among hard-to-reach populations remains a global issue. The current study aimed to assess the feasibility of a modified same-day test-and-treat model in improving HCV care for people who inject drugs (PWID) living in resource-constrained rural areas. METHODS: A pilot study was conducted in four primary healthcare (PHC) centers in Malaysia. The model's key features included on-site HCV ribonucleic acid (RNA) testing using a shared GeneXpert® system; noninvasive biomarkers for cirrhosis diagnosis; and extended care to PWID referred from nearby PHC centers and outreach programs. The feasibility assessment focused on three aspects of the model: demand (i.e., uptake of HCV RNA testing and treatment), implementation (i.e., achievement of each step in the HCV care cascade), and practicality (i.e., ability to identify PWID with HCV and expedite treatment initiation despite resource constraints). RESULTS: A total of 199 anti-HCV-positive PWID were recruited. They demonstrated high demand for HCV care, with a 100% uptake of HCV RNA testing and 97.4% uptake of direct-acting antiviral treatment. The rates of HCV RNA positivity (78.4%) and sustained virologic response (92.2%) were comparable to standard practice, indicating the successful implementation of the model. The model was also practical, as it covered non-opioid-substitution-therapy-receiving individuals and enabled same-day treatment in 71.1% of the participants. CONCLUSIONS: The modified same-day test-and-treat model is feasible in improving HCV care for rural PWID. The study finding suggests its potential for wider adoption in HCV care for hard-to-reach populations.

Knowledge, Perception and Barriers to Cancer Pain Management among Doctors in Malaysia.

Background: Pain remains common in people living with advanced cancer and is often inadequately managed. This study was designed to assess knowledge, perceptions and barriers to morphine use in cancer pain management among doctors in Malaysia. Methods: Doctors from multiple disciplines in a general hospital were invited to complete a 39-item self-reported questionnaire between November 2020 and December 2020. Each question was based on a 5-point Likert scale (1 = strongly disagree; 5 = strongly agree). 'Agree' and 'strongly agree' were considered correct or positive responses, except for nine questions worded in the opposite direction. Associations between variables were confirmed using Pearson's chi-squared and Fisher's exact tests. Results: Most respondents were house officers (206/321; 64.2%) with less than two years of service, followed by medical officers (68/321; 21.2%) and specialists (47/321; 14.6%). Only 7.2% of the respondents had received formal palliative care training before the study. Of the respondents, 73.5% were aware of the World Health Organization (WHO) analgaesic ladder, 60.7% were correct on oral morphine as the first line for moderate to severe cancer pain treatment and 91.9% knew the need to add rescue morphine for breakthrough pain. Additionally, 34.0% (P < 0.001) perceived morphine use caused addiction, 57.9% (n = 186) expressed fear of respiratory depression and 18.3% of medical officers and specialists perceived limited access and a maximum dose to prescribe. There was a significant difference in knowledge and perception between junior doctors and senior clinicians. The majority strongly agreed and agreed that there were inadequate training opportunities in cancer pain management. Conclusion: Inconsistent knowledge and negative perceptions of cancer pain management among doctors were demonstrated in this study.

Detecting dysglycaemia in compensated liver cirrhosis: Comparison of oral glucose tolerance test and glycated haemoglobin, with continuous glucose monitoring.

AIMS: Liver cirrhosis increases the risk of developing dysglycaemia (pre-diabetes and diabetes), thus people with cirrhosis should undergo regular screening for dysglycaemia. The utility of screening using the laboratory glycated haemoglobin (HbA1c ) test has been questioned in this setting. This study examines the relationship between different potential screening modalities: 75 g oral glucose tolerance test (OGTT) and HbA1c , using continuous glucose monitoring (CGM) as a comparator. METHODS: Participants ≥18 years with no known diabetes, were recruited from a gastroenterology cirrhosis surveillance register. Study measurements included a 75 g OGTT, laboratory HbA1c and two weeks of 'blinded' CGM (Freestyle Libre Pro). The possibility of intravascular haemolysis affecting HbA1c interpretation was also assessed. RESULTS: All 20 participants had compensated cirrhosis. OGTT tended to diagnose more dysglycaemia (N = 7) than did HbA1c (N = 4). Bland-Altman analysis showed laboratory and CGM-estimated HbA1c were broadly comparable, with a difference of 4mmol/mol (95% CI -3 to 12), or 0.4% (95% CI -0.3 to 1.1). Laboratory HbA1c tended to be higher than the CGM-estimated HbA1c , perhaps reflecting positive lifestyle changes in participants during their two weeks of wearing 'blinded' CGM (Hawthorne effect). In the population studied, there was no evidence that haemolysis affected interpretation of HbA1c results. CONCLUSIONS: In the setting of compensated cirrhosis, the OGTT and HbA1c remain standard screening test for diabetes, but multiple studies show the OGTT diagnoses more people with dysglycaemia than does the HbA1c . Blinded CGM in an ambulatory, real world setting provides additional insights into glycaemic excursions but cannot be used to diagnose dysglycaemia.

Barriers to scaling up hepatitis C treatment in Malaysia: a qualitative study with key stakeholders.

BACKGROUND: While the availability of generic direct-acting antivirals (DAAs) opens the door for large-scale treatment, the care for people living with hepatitis C virus (HCV) in Malaysia is shifting toward a tripartite partnership between the public health system, correctional settings and civil society organizations (CSOs). This study aimed to explore the barriers to scaling up HCV treatment in Malaysia from the perspective of key stakeholders. METHODS: Eighteen focus-group discussions (FGDs) were conducted with 180 individuals, who actively engaged in coordinating, executing or supporting the implementation of the national strategic plan for HCV. An analytical framework was adapted to guide the data collection and thematic analysis. It covered four key aspects of HCV treatment: geographical accessibility, availability, affordability and acceptability. RESULTS: Movement restrictions in times of coronavirus disease 2019 (COVID-19) outbreaks and being marginalized translated into barriers to treatment access in people living with HCV. Barriers to treatment initiation in health and correctional settings included limited staffing and capacity; disruption in material supply; silos mentality and unintegrated systems; logistical challenges for laboratory tests; and insufficient knowledge of care providers. Although no-cost health services were in place, concerns over transportation costs and productivity loss also continued to suppress the treatment uptake. Limited disease awareness, along with the disease-related stigma, further lowered the treatment acceptability. CONCLUSIONS: This study disclosed a series of supply- and demand-side barriers to expanding the treatment coverage among people living with HCV in Malaysia. The findings call for strengthening inter-organizational collaborations to overcome the barriers.

Health-related quality of life of Malaysian patients with chronic non-malignant pain and its associated factors: a cross-sectional study.

BACKGROUND: Chronic pain has a major impact on a patient's quality of life, affecting physical and psychological functioning. It has debilitating consequences on social and economic aspects too. This study aimed to explore the status of health-related quality of life (HRQoL) of Malaysian patients suffering from chronic non-malignant pain. METHODS: Four hospitals offering pain clinic services were involved in this multicentre cross-sectional study conducted between June and September 2020. Adult patients who had been diagnosed with non-malignant chronic pain lasting for at least three months and able to communicate in English or Malay language were recruited in this study. Participants were informed about the study and were made aware that their participation was entirely voluntary. A battery of questionnaires consists of the EuroQol-5 dimensions-5 levels questionnaire (EQ-5D-5L) and the EuroQol visual analogue scale (EQ VAS), the Pain Self-Efficacy questionnaire (PSEQ) and the Pain Catastrophizing Scale (PCS) were self-administered by the patients. Besides, a structured questionnaire was used to collect their socio-demographic information, pain condition, sleep quality and working status. Participants' usage of pain medications was quantified using the Quantitative Analgesic Questionnaire (QAQ). RESULTS: A total of 255 patients participated in this study. A median EQ-5D index value of 0.669 (IQR: 0.475, 0.799) and a median EQ VAS score of 60.0 (IQR: 50.0, 80.0) were recorded. Malay ethnicity (Adj. B: 0.77; 95% CI: 0.029, 0.126; p = 0.002) and a higher level of self-efficacy (Adj. B: 0.008; 95% CI: 0.006, 0.011; p < 0.001) were predictors of a better HRQoL, while suffering from pain in the back and lower limb region (Adj. B: -0.089; 95% CI: - 0.142, - 0.036; p = 0.001), the use of a larger amount of pain medications (Adj. B: -0.013; 95% CI: - 0.019, - 0.006; p < 0.001), and a higher degree of pain magnification (Adj. B: -0.015; 95% CI: - 0.023, - 0.008; p < 0.001) were associated with a poorer HRQoL. CONCLUSIONS: These findings suggested that Malay ethnicity and a higher level of self-efficacy were predictors of a better HRQoL in patients with chronic pain, whereas pain-related factors such as higher usage of medication, specific pain site and pain magnification style were predictors of poorer HRQoL.

Medication-related knowledge, administration practice and adherence among caregivers of chronically ill children in Malaysia.

BACKGROUND: Caregivers' knowledge, practice and adherence in medication administration who care for children with chronic illness requiring long-term pharmacological treatments are factors associating with children medication safety at home. This study aimed to determine the medication-related knowledge, administration practice and adherence among caregivers of chronically ill children in Malaysia. This cross-sectional study was conducted at the paediatric outpatient clinic of a tertiary public hospital. Caregivers of chronically ill children, who engaged in medication administration at home for at least 3 months, were conveniently recruited. Their medication-related knowledge and administration practice were evaluated based on a checklist, while their adherence to medication administration was assessed using a validated 5-point scale. The associated factors were also explored. RESULTS: Of the 141 participants, most were mothers (90.8%) and had a full-time job (55.3%). Most of them had adequate medication-related knowledge (71.6%) and an appropriate administration practice (83.0%). The majority of them (83.0%) also rated themselves as adherent to medication administration. The participants with a child above 5 years of age (91.2%) were found to have a better practice than those with younger children (75.3%) in medication administration (p = 0.012). However, those with a child taking two (adjusted OR: 12.53) or three (adjusted OR: 8.29) medications, getting their refills from private health institutions apart from this hospital (adjusted OR = 7.06) and having multiple illnesses (adjusted OR = 21.25) were more likely to be not adherent to medication administration. CONCLUSION: Caregivers of chronically ill children in Malaysia generally have sufficient knowledge and an appropriate practice of medication administration at home. Yet, strategies to improve the adherence to medication administration, particularly in those who care for children with complicated health conditions, are warranted.

Find the Missing Millions: Malaysia's experience with nationwide hepatitis C screening campaign in the general population.

Approximately 2.5% of the Malaysian population is currently living with hepatitis C virus (HCV) infection. Yet, the public awareness of the disease is limited and under-screening remains a major challenge. With the support of international non-for-profit organizations, the Ministry of Health in Malaysia recently launched a one-week nationwide hepatitis C screening campaign in conjunction with the World Hepatitis Day. For the first time, the rapid diagnostic test (RDT) for HCV screening was introduced in public health institutions. This campaign involved 49 hospitals and 38 health clinics across the country, targeting the adult general population with unknown HCV infection status. Of the 11 382 participants undergoing the RDT, 1.9% were found to be positive for hepatitis C antibody (anti-HCV) and were referred to on-site medical departments or nearby hospitals for confirmatory testing and treatment. Men, the Malay ethnic group, intranasal and injection drug users and ex-prisoners were shown to have higher odds of being positive for anti-HCV. In addition to serving as a model to educate the general population about the disease, this campaign demonstrates the feasibility of decentralizing HCV screening, particularly by promoting the use of RDT, and linking the HCV-infected patients to care in Malaysia.

Cutaneous adverse events in a randomized controlled trial of flash glucose monitoring among youth with type 1 diabetes mellitus.

BACKGROUND: The literature regarding flash glucose monitoring (FGM)-associated cutaneous adverse events (AE) is limited. OBJECTIVES: This study among youth participating in a 6 month randomized controlled trial aimed to compare cutaneous AE between FGM and self-monitored blood glucose (SMBG) use and evaluate premature FGM sensor loss. METHODS: Patients aged 13 to 20 years with type 1 diabetes were randomized to intervention (FGM and usual care) or control (SMBG and usual care). Participants self-reported cutaneous AEs electronically every 14 days. Reports were analyzed to determine frequency, type, and severity of cutaneous AEs, and evaluate premature sensor loss. RESULTS: Sixty-four participants were recruited; 33 randomized to FGM and 31 to control. In total, 80 cutaneous AEs were reported (40 in each group); however, the proportion of participants experiencing cutaneous AEs was greater in the FGM group compared to control (58% and 23% respectively, P = .004). FGM participants most frequently reported erythema (50% of AEs), while controls most commonly reported skin hardening (60% of AEs). For FGM users, 80.0% of cutaneous AEs were mild, 17.5% moderate, and 2.5% severe. Among controls, 82.5% of cutaneous AEs were mild and 17.5% moderate. One participant ceased using FGM due to recurring cutaneous AEs. Additionally, over 6 months, 82% of FGM participants experienced at least one premature sensor loss, largely unrelated to a cutaneous AE. CONCLUSIONS: Cutaneous FGM-associated AEs are common, and mostly rated as mild. However, the majority of users continued FGM despite cutaneous AEs. Awareness of cutaneous complications and mitigation measures may reduce cutaneous AEs and improve the overall experience of FGM.

Hepatic adverse drug reactions in Malaysia: An 18-year review of the national centralized reporting system.

PURPOSE: To determine the incidence, demographic profile, background of reporters, causative agents, severity and clinical outcomes of hepatic adverse drug reaction (ADR) reports in Malaysia using the national ADR reporting database. METHODS: The ADR reports recorded between 2000 and 2017 were retrospectively analysed to identify hepatic ADR reports. The trend and characteristics of hepatic ADR cases were described. Multivariate disproportionality analysis of the causative agents was performed to generate signals of hepatic ADRs. RESULTS: A total of 2090 hepatic ADRs (1.77% of all ADRs) were reported with mortality rate of 12.7% among cases with known clinical outcomes. The incidence of hepatic ADR reporting in Malaysia increased significantly over 18 years from 0.26 to 9.45 per million population (P < .001). Antituberculosis drugs (n = 268, 12.82%) was the most common suspected class of causative agents with a reporting odds ratio (ROR) and 95% CI of 8.39 (7.26-9.70), followed by traditional/complementary medicines or herbal/dietary supplements (TCM/HDS) (n = 235, 11.24%, ROR 3.26 [2.84-3.75]), systemic antibacterials (n = 159, 7.61%, ROR 2.65 [2.25-3.13]), lipid modifying agents (n = 142, 6.79%, ROR 2.21 [1.86-2.63]) and amiodarone (n = 137, 6.56%, ROR 35.25 [28.40-43.75]). Most (72.9%) of the TCM/HDS were not registered with the authorities. CONCLUSIONS: Hepatic ADR cases have increased significantly in Malaysia, with antituberculosis drugs, systemic antibacterials, and TCM/HDS being the most common causative agents reported. Most TCM/HDS reported to be associated with hepatic ADR were not registered with the authorities.

Medication Safety at Home: A Qualitative Study on Caregivers of Chronically Ill Children in Malaysia.

Introduction: Medication errors are more likely to occur in chronically ill children, who are highly dependent on caregivers for medication administration. This study aimed to explore the issues related to medication safety among pediatric outpatients in Malaysia from the caregivers' perspective. Methods: This was a qualitative study conducted between May and June 2018 at a pediatric clinic of a regional referral hospital. Caregivers of children who (1) were under 6 years of age and (2) had hypothyroidism, epilepsy, thalassemia, asthma, or other chronic diseases were recruited via purposive sampling. Each selected disease was represented by at least 3 caregivers, who were identified from the medical records of their children. Face-to-face interviews were conducted with each of them, facilitated by a semi-structured interview guide. All the interviews were audio-recorded, transcribed verbatim, and analyzed using the thematic analysis approach. Results: A total of 15 mothers with a median age of 34 years were interviewed. Three themes emerged from the interviews: (I) actual experiences with medication errors, (II) underlying risk factors for medication errors, and (III) recommendations to improve medication safety. Several cases of administration errors, including missed doses and self-decided dose adjustment, were detected. Furthermore, the caregivers were found to have inadequate understanding of the medications in general. Conclusions: While children were shown to be consistently exposed to medication errors at home in Malaysia, the recommendations of the caregivers, including the use of written instructions and a diary, could be effective strategies to improve the out-of-hospital medication safety in children.

Knowledge and Attitudes Concerning Antibiotic Use and Resistance among the Public in Pulau Pinang, Malaysia.

The aim of this cross-sectional study was to evaluate the knowledge and attitudes concerning antibiotic use and resistance among members of the local community in Pulau Pinang, Malaysia. The study was conducted among 326 residents of the Jelutong district, Pulau Pinang state, from August to October 2013. A self-administered five-part questionnaire was used for the data collection. The respondents exhibited inadequate knowledge of antibiotics in general. Approximately 80% of them did not know the indications for antibiotic use, while 76% believed that antibiotics were useful in terms of resolving viral fever. Additionally, 52.6% believed that antibiotics could be used to treat all types of infections. Inadequate knowledge of antibiotic resistance was also evident among the respondents, since 72.9% of them did not agree that resistant bacteria can spread from human or animal to human, while 32% were unaware that bacteria can develop resistance to antibiotics. More than 60% of respondents admitted that they took antibiotics in order to accelerate their recovery from illness, while 34.8% claimed that they only stopped taking antibiotics when they felt better. The findings hence indicate that most respondents had poor knowledge and attitudes concerning antibiotic use and resistance, which suggests the need for more community-based educational campaigns designed to improve the public's knowledge and attitudes regarding antibiotics.

Retrospective observational comparative study of Hemilaminectomy versus Laminectomy for intraspinal tumour resection; Shorter Stays, Lower Analgesic Usage and Less Kyphotic Deformity.

INTRODUCTION: Intraspinal tumours are rare and principally managed surgically. Laminectomy, employed for access to the spinal canal, destroys the posterior tension band leading to a risk of kyphosis. Hemilaminectomy as an alternative may be less destructive, potentially reducing the risk of deformity and causing less post-operative pain. METHOD: We investigated this hypothesis by retrospectively reviewing a case series of 56 surgeries for a disparate and unselected group of intraspinal tumours utilizing a laminectomy or hemilaminectomy approach. RESULTS: No difference was found in length of operation, completeness of resection, complication rate and Frankel-score improvements. Hemilaminectomy (n = 22) is associated with reduced hospital stay (post-op days) 4.5 (2-6) versus 6 (3-8), (p = 0.026, Mann-Whitney), and a reduction in post-operative morphine use (mg) 10 (3.5-28) versus 30 (10-90), (p = 0.005, Mann-Whitney). Post-operative kyphosis was measured with the Harrison posterior tangent method on T2-weighted sagittal MR images. The average change in kyphosis angle was greater in the laminectomy group compared with the hemilaminectomy group, 3.6 (0.8-6.2) versus 0.4 (-0.2-1.2), statistically significant (p = 0.004, Mann-Whitney). CONCLUSION: Hemilaminectomy is as effective an access procedure for the resection of unselected intraspinal tumours as laminectomy, but is associated with shorter post-operative stays, lower analgesic requirements and less post-operative kyphosis.

A novel technique of detecting MRI-negative lesion in focal symptomatic epilepsy: intraoperative ShearWave elastography.

Focal symptomatic epilepsy is the most common form of epilepsy that can often be cured with surgery. A small proportion of patients with focal symptomatic epilepsy do not have identifiable lesions on magnetic resonance imaging (MRI). The most common pathology in this group is type II focal cortical dysplasia (FCD), which is a subtype of malformative brain lesion associated with medication-resistant epilepsy. We present a patient with MRI-negative focal symptomatic epilepsy who underwent invasive electrode recordings. At the time of surgery, a novel ultrasound-based technique called ShearWave Elastography (SWE) was performed. A 0.5 cc lesion was demonstrated on SWE but was absent on B-mode ultrasound and 3-T MRI. Electroencephalography (EEG), positron emission tomography (PET), and magnetoencephalography (MEG) scans demonstrated an abnormality in the right frontal region. On the basis of this finding, a depth electrode was implanted into the lesion. Surgical resection and histology confirmed the lesion to be type IIb FCD.

Plasma glucose measurement in diabetes: impact and implications of variations in sample collection procedures with a focus on the first hour after sample collection.

BACKGROUND: Previous studies of participants with plasma glucose concentrations at or near the glucose reference range demonstrate glucose loss following delayed separation and extraction of plasma from the cellular components of blood, of ≤7% per hour. We aimed to assess pre-analytical glucose loss in diabetic subjects, focusing on the first hour after sample collection. METHODS: Venous blood was collected from diabetes clinic attendees, into a series of lithium heparin PST™ (plasma separator tube) and fluoride oxalate Vacutainers™. Baseline (reference) plasma glucose measurements were undertaken on samples prepared under refrigerated conditions. The remaining samples underwent a series of controlled pre-analytical delays in sample preparation, at room temperature. Plasma glucose was measured using the hexokinase method. RESULTS: Median baseline glucose (mmol/L) for the 62 participants was 10.6 (range 3.4-31.1). Using lithium heparin PST™ tubes, mean glucose loss (95% CI) was 0.16 (0.09-0.23) after 30 min delay in plasma preparation and 0.28 (0.21-0.34) after 60 min delay. Glucose loss was independent of both baseline glucose and also individual cellular count. Fluoride failed to inhibit glucose loss within the first hour after sample collection. Immediate plasma centrifugation of PST™ tubes, followed by delayed plasma extraction (median delay 92 min), produced a mean glucose loss of 0.02 mmol/L (-0.05-0.09). CONCLUSIONS: Samples collected into lithium heparin PST™ tubes show pre-analytical glucose loss at 1 h that is independent of baseline glucose and cellular count. Furthermore, immediate plasma separation using these tubes attenuates glucose loss across a wide range of glucose concentrations.

Hibiscus score: Developing and validating a predictive tool for intravenous immunoglobulin treatment resistance in Malaysian children with Kawasaki disease.

BACKGROUND: Children with intravenous immunoglobulin (IVIG) resistant Kawasaki disease (KD) are at higher risk of developing coronary artery (CA) aneurysm. Early identification of high-risk patients using a predictive tool would allow for earlier interventions to prevent cardiac complications. METHODS: Children with KD who were admitted to five selected hospitals in Malaysia between 2008 and 2018 and received 2 g/kg of IVIG within 10 days from the onset of illness were included. Predictors of IVIG resistance in KD were determined using multiple logistic regression analysis. An optimal cut-off point was set using receiver operative characteristic curve and a final multiple logistic regression analysis was performed entering these cut-off points. A new scoring system was constructed. RESULTS: A total of 276 patients were included. IVIG resistance occurred in 9.1 % of them. Total bilirubin [OR 7.37; 95 % CI (2.18, 24.83)], male sex [OR 0.34; 95 % CI (0.10, 1.19)], C-reactive protein (CRP) [OR 0.17; 95 % CI (0.02, 1.38)] and neutrophils [OR 0.25; 95 % CI (0.05, 1.21)] were found to be significant predictors for IVIG resistance. The findings led to the development of a new predictive tool called the Hibiscus score, which scored 1 point each for neutrophils ≥60 %, CRP ≥80 mg/L, and male sex, while total bilirubin ≥9.4 µmol/L scored 2 points. A cut-off point of ≥4 with this prediction score yielded a sensitivity of 78.9 % and specificity of 80.5 %, with area under the curve of 0.835 [95 % CI (0.752, 0.919)]. CA aneurysms occurred in 6.7 % of IVIG responders and 32 % of IVIG-resistant children (p < 0.001). CONCLUSION: The findings suggest that the Hibiscus score has a higher predictive power than the existing scoring systems for IVIG resistance in children with KD in Malaysia. However, external validation is required to enable its use to guide treatment decisions.

Association of Clinical Characteristics With Familial Hypercholesterolaemia Variants in a Lipid Clinic Setting: A Case-Control Study.

Objective: Familial hypercholesterolaemia (FH) variant positive subjects have over double the cardiovascular risk of low-density-lipoprotein-cholesterol (LDL-C) matched controls. It is desirable to optimise FH variant detection. Methods: We identified 213 subjects with FH gene panel reports (LDLR, APOB, PCSK9, and APOE) based on total cholesterol >310 mg/dL; excluding triglycerides >400 mg/dL, cascade screening, and patients without pre-treatment LDL-C recorded. Demographic, clinical and lipid parameters were recorded. Results: A 31/213 (14.6%) patients had pathogenic or likely pathogenic FH variants. 10/213 (4.7%) had variants of uncertain significance. Compared with patients without FH variants, patients with FH variants were younger (median age, 39 years vs. 48 years), had more tendon xanthomata (25.0% vs. 11.4%), greater proportion of first degree relatives with total cholesterol >95th percentile (40.6% vs. 16.5%), higher LDL-C (median, 271 mg/dL vs. 236 mg/dL), and lower triglycerides (median, 115 mg/dL vs. 159 mg/dL). The Besseling et al. model (c-statistic 0.798) improved FH variant discrimination over Friedewald LDL-C (c-statistic 0.724), however, Dutch Lipid Clinic Network Score (DLCNS) did not (c-statistic 0.665). Sampson LDL-C (c-statistic 0.734) had similar discrimination to Friedewald. Conclusion: Although tendon xanthomata and first degree relatives with high total cholesterol >95th percentile were associated with FH variants, DLCNS or Simon Broome criteria did not improve FH detection over LDL-C. Sampson LDL-C did not significantly improve discrimination over Friedewald. Although lower triglycerides and younger age of presentation are positively associated with presence of FH variants, this information is not commonly used in FH detection algorithms apart from Besseling et al.
