    OBJECTIVE: We assessed whether hematoma expansion (HE) and favorable outcome differ according to type of intracerebral hemorrhage (ICH).

    METHODS: Among participants with ICH enrolled in the TICH-2 (Tranexamic Acid for Hyperacute Primary Intracerebral Haemorrhage) trial, we assessed baseline scans for hematoma location and presence of cerebral amyloid angiopathy (CAA) using computed tomography (CT, simplified Edinburgh criteria) and magnetic resonance imaging (MRI; Boston criteria) and categorized ICH as lobar CAA, lobar non-CAA, and nonlobar. The main outcomes were HE and favorable functional outcome. We constructed multivariate regression models and assessed treatment effects using interaction terms.

    RESULTS: A total of 2,298 out of 2,325 participants were included with available CT (98.8%; median age = 71 years, interquartile range = 60-80 years; 1,014 female). Additional MRI was available in 219 patients (9.5%). Overall, 1,637 participants (71.2%) had nonlobar ICH; the remaining 661 participants (28.8%) had lobar ICH, of whom 202 patients had lobar CAA-ICH (8.8%, 173 participants according to Edinburgh and 29 participants according to Boston criteria) and 459 did not (lobar non-CAA, 20.0%). For HE, we found a significant interaction of lobar CAA ICH with time from onset to randomization (increasing risk with time, pinteraction

    A consecutive series of 2,277 patients presenting for upper gastrointestinal endoscopy was analysed. The following groups of patients were studied with reference to sex, race and dialect groups: those presenting with dyspepsia but no haemorrhage, those presenting with upper gastrointestinal haemorrhage, those with non-ulcer dyspepsia, gastric ulcer and duodenal ulcer. Males out-numbered females in all diagnostic groups. Male and female Malays were under-represented in all diagnostic groups when compared to the Singapore population. Amongst female Chinese, there was an excess of Cantonese patients and an under-representation of Teochew patients in most diagnostic groups. These dialect differences were not remarkable amongst male Chinese. The possible reasons for these differences and their significance are discussed.

    Intracranial haemorrhage is a major cause of severe morbidity and mortality in child abuse cases in developed countries. However, similar data are not available in most developing countries. This study therefore aimed to determine the incidence of intracranial haemorrhage amongst all cases of child physical abuse, the nature of the injuries incurred, and the morbidity and mortality resulting therefrom. Among 369 cases of physical abuse seen over a 4-year period, 41 (11.4%) had intracranial haemorrhage, of whom 37 (90%) were 2 years old or less. A history of trauma was present in only eight (20%), of which only two were compatible with the injuries incurred. Subdural haemorrhages accounted for 80% of the cases, with skull fractures present in only nine cases. Fifty-four per cent of the 37 children aged 2 years of age or less had no external signs of trauma, but 11 of them had retinal haemorrhages. This is in contrast to the children older than 2 years of age who all had external signs of trauma. The overall prognosis was dismal with an early mortality of almost 30% (13 cases) and at least seven cases with severe neurological sequelae. These findings are comparable with studies from developed countries which have established that non-accidental injury must be considered as a cause of intracranial haemorrhage in any young child, despite the absence of external signs of trauma.

    BACKGROUND: Patients' delay in the presentation with rectal bleeding had been identified as a factor for late diagnosis of colorectal cancer. This study was conducted to determine the prevalence of delay in consulting a medical practitioner and identifying associated factors.

    MATERIALS AND METHODS: A cross-sectional study of 80 patients with rectal bleeding, aged 40 and above, was conducted between December 2008 and June 2009 in the endoscopy unit, University Kebangsaan Malaysia Medical Centre. The self-administered questionnaire included data on sociodemographic, concern of rectal bleeding, whether patients sought initial advice, any self treatment prior to medical consultation and patients' opinion on causes of their own rectal bleeding.

    RESULTS: The prevalence of delay in the presentation of rectal bleeding was 60%. Patients who were less worried (OR 9.6; 95% CI 3.3-27.5), who did not seek anyoneandapos;s advice (OR 11.8; 95% CI 3.8-36.8) and took some treatment before seeking medical consultation (OR 5.0; 95% CI 1.0-24.1) were significantly more likely to delay. Multiple logistic regression revealed that less worry of rectal bleeding and not seeking anyoneandapos;s advice were important predictors (p<0.05). The majority of patients attributed their bleeding to benign causes.

    CONCLUSION: A high proportion of patients with rectal bleeding in the high risk group delayed in seeking medical advice. Public education needs to focus on interventions to reduce the delay in presenting and diagnosis of colorectal carcinoma.

    INTRODUCTION: Adolescent motherhood (childbearing below 18 years of age) is a major global health and social problem. Understanding the impact of early motherhood on maternal and child health indices is important to community and population health promotion in developing countries. This study examined the association between adolescent motherhood and maternal and child health indices in Maiduguri, Nigeria.

    METHODS: A cross-sectional design method was used to recruit 220 mothers (age=14-25 years) from four communities in the city of Maiduguri, Northeastern Nigeria. Participants were surveyed using a self-developed interviewer-administered questionnaire that assesses maternal and child health indices and sociodemographic characteristics. Logistic regression analysis was used to compute adjusted OR and 95% CI of the associations between motherhood in adolescence (mothers below 18 years old) and maternal and child health indices.

    RESULTS: Compared to adult mothers, adolescent mothers were more likely to experience fistula (OR=5.01, 95% CI=3.01 to 14.27), to have postpartum haemorrhage (OR=6.83, 95% CI=2.93 to 15.92), to have sexually transmitted infections (OR=6.29, 95% CI=2.26 to 17.51) and to lose a child within 5 years of birth (OR=3.52, 95% CI=1.07 to 11.60). Children born to adolescent mothers were less likely to have normal weight at birth (OR=0.34, CI=0.15 to 0.73) than those born to adult mothers.

    CONCLUSION: Adolescent motherhood was associated with negative maternal and child health indices. The findings can be used by public health professionals including physiotherapists in this role to inform effective primary healthcare practice and community health advocacy to improve maternal and child health indices among adolescent mothers in Maiduguri. Future studies are needed to confirm the evidence at the regional or national level including the rural population in Nigeria.

    A new enterovirus, now classified as enterovirus type 70, was isolated from the conjunctiva of patients with acute haemorrhagic conjunctivitis during the 1971 epidemics that occurred in Japan, Singapore, and Morocco. These epidemics were parts of a pandemic involving Africa (Algeria, Ghana, Morocco, Nigeria, and Tunisia), Asia (Cambodia, China (Province of Taiwan), Hong Kong, India, Indonesia, Japan, Malaysia, the Philippines, Singapore, and Thailand), and England during 1969-71. A representative strain from each of the three epidemic areas was studied cooperatively. The strains exhibited the physicochemical characteristics of enteroviruses. Cross-neutralization tests showed that these viruses were distinct from all known human enterovirus immunotypes, but that they were antigenically closely related. The human origin of the viruses was demonstrated by the appearance of homologous neutralizing antibodies during convalescence in patients with acute haemorrhagic conjunctivitis.

    INTRODUCTION: Anticoagulation therapy is the fundamental approach for stroke prevention in atrial fibrillation (AF) patients. Numerous systematic reviews comparing anticoagulation strategies have been published. We aim to summarize the efficacy and safety evidence of these strategies in AF patients from previously published systematic reviews.

    METHODS: We searched PubMed, EMBASE and Cochrane library from inception to Feb 24th, 2017, to identify systematic reviews and meta-analyses of randomized controlled trials that assessed interventions or strategies to improve oral anticoagulant use in AF patients.

    RESULTS: Thirty-four systematic reviews were eligible for inclusion but only 11 were included in the qualitative analyses, corresponding to 40 unique meta-analyses, as the remaining systematic reviews had overlapping primary studies. There was insufficient evidence to support the efficacy of genotype-guided dosing and pharmacist-managed anticoagulation clinics for stroke prevention in AF patients. Conversely, patient's self-management and novel oral anticoagulants (NOACs), in general were superior to warfarin for preventing stroke and reducing mortality. All interventions showed comparable risk of major bleeding with warfarin.

    CONCLUSION: Findings from this overview support the superiority of NOACs and patient's self-management for preventing stroke in AF patients. However, uncertainties remain on the benefits of genotype-guided dosing and pharmacist-managed anticoagulation clinics due to poor quality evidence, and future research is warranted.

    OBJECTIVES: Maternal periodontitis has been suggested as one of the risk factors for low birth weight (LBW) infants. The objective of this study was to determine the association between maternal periodontitis and LBW infants among Malay women.

    METHODS: Screening periodontal examinations were carried out on all eligible Malay pregnant women in the second trimester of pregnancy attending two randomly selected community maternal and child health clinics in Kota Bharu, Kelantan. Patients with four or more sites with pocket depth 4 mm or higher, and clinical attachment loss 3 mm or higher at the same site with presence of bleeding on probing were diagnosed as having periodontitis in this study. Using this definition, systematic random sampling was utilized for selection of 250 subjects for each exposed and non-exposed group. Of 500 subjects enrolled in the study, 28 (5.6%) were either dropped or lost to follow-up. Of the remaining 472 subjects, 232 with periodontitis were in the exposed group and 240 with healthy periodontium were in the nonexposed group.

    RESULTS: The incidence of LBW was 14.2% (95% CI: 9.70-18.75) in women with periodontitis, and 3.3% (95% CI: 1.05-5.62) in women without periodontitis. The relative risk of having LBW infants was 4.27 times higher for women with periodontitis compared with those without periodontitis (95% CI: 2.01-9.04). After adjustment for potential confounders using multiple logistic regression analysis, significant association was found between maternal periodontitis and LBW (OR = 3.84; 95% CI: 1.34-11.05).

    CONCLUSION: The results of this study provide additional evidence that pregnant women with periodontitis are at a significantly higher risk of delivering LBW infants.

    BACKGROUND & AIMS: Antiplatelets and anticoagulants are associated with increased upper gastrointestinal bleeding. We evaluated whether proton pump inhibitor therapy could reduce this risk.

    METHODS: We performed a 3 × 2 partial factorial double-blind trial of 17,598 participants with stable cardiovascular disease and peripheral artery disease. Participants were randomly assigned to groups given pantoprazole 40 mg daily or placebo, as well as rivaroxaban 2.5 mg twice daily with aspirin 100 mg once daily, rivaroxaban 5 mg twice daily, or aspirin 100 mg alone. The primary outcome was time to first upper gastrointestinal event, defined as a composite of overt bleeding, upper gastrointestinal bleeding from a gastroduodenal lesion or of unknown origin, occult bleeding, symptomatic gastroduodenal ulcer or ≥5 erosions, upper gastrointestinal obstruction, or perforation.

    RESULTS: There was no significant difference in upper gastrointestinal events between the pantoprazole group (102 of 8791 events) and the placebo group (116 of 8807 events) (hazard ratio, 0.88; 95% confidence interval [CI], 0.67-1.15). Pantoprazole significantly reduced bleeding of gastroduodenal lesions (hazard ratio, 0.52; 95% confidence interval, 0.28-0.94; P = .03); this reduction was greater when we used a post-hoc definition of bleeding gastroduodenal lesion (hazard ratio, 0.45; 95% confidence interval, 0.27-0.74), although the number needed to treat still was high (n = 982; 95% confidence interval, 609-2528).

    CONCLUSIONS: In a randomized placebo-controlled trial, we found that routine use of proton pump inhibitors in patients receiving low-dose anticoagulation and/or aspirin for stable cardiovascular disease does not reduce upper gastrointestinal events, but may reduce bleeding from gastroduodenal lesions.

    BACKGROUND AND AIMS: Wire-guided biliary cannulation has been demonstrated to improve cannulation rates and reduce post-ERCP pancreatitis (PEP), but the impact of wire caliber has not been studied. This study compares successful cannulation rates and ERCP adverse events by using a 0.025-inch and 0.035-inch guidewire.

    METHODS: A randomized, single blinded, prospective, multicenter trial at 9 high-volume tertiary-care referral centers in the Asia-Pacific region was performed. Patients with an intact papilla and conventional anatomy who did not have malignancy in the head of the pancreas or ampulla and were undergoing ERCP were recruited. ERCP was performed by using a standardized cannulation algorithm, and patients were randomized to either a 0.025-inch or 0.035-inch guidewire. The primary outcomes of the study were successful wire-guided cannulation and the incidence of PEP. Overall successful cannulation and ERCP adverse events also were studied.

    RESULTS: A total of 710 patients were enrolled in the study. The primary wire-guided biliary cannulation rate was similar in 0.025-inch and 0.035-inch wire groups (80.7% vs 80.3%; P = .90). The rate of PEP between the 0.025-inch and the 0.035-inch wire groups did not differ significantly (7.8% vs 9.3%; P = .51). No differences were noted in secondary outcomes.

    CONCLUSION: Similar rates of successful cannulation and PEP were demonstrated in the use of 0.025-inch and 0.035-inch guidewires. (Clinical trial registration number: NCT01408264.).

    The influence of the age of onset of symptoms on various clinical features of peptic ulcer was studied in a personal series of 492 patients (duodenal ulcer 363, gastric ulcer 98, combined gastric and duodenal ulcer 31). Duodenal ulcer patients whose age of onset of symptoms was within the first three decades (n = 166) were more likely to be men (77%) and to have a positive family history of dyspepsia (45%) and a history of haemorrhage (46%) when compared with late onset patients (n = 197, men 57%, positive family history 23%, history of haemorrhage 36%). Early onset duodenal ulcer patients also secreted more gastric acid than late onset patients. In contrast, while early onset gastric ulcer patients were more likely to be men, when compared to late onset patients, the two groups were similar in their family history of dyspepsia, their history of haemorrhage, and their gastric acid output. The age of onset of Malay duodenal ulcer patients (mean (SD) 43.6 (16.0] was higher than those for Chinese patients (33.7 (16.1].

    BACKGROUND/AIMS: Recently an increasing number of young colorectal carcinoma patients attending the University Hospital, Kuala Lumpur were noted. This report represents our experience with patients suffering from colorectal cancer aged 30 years or younger.
    MATERIALS AND METHODS: All cases of primary carcinoma of the colon and rectum admitted to the University Hospital during 1990 to 1994 were respectively reviewed. Inclusion criteria was that the patient had been 30 years or younger. Data collected included age, gender, race, site of tumour, presenting symptomatology, duration of symptoms, histology, extension of tumour and nodal involvement predisposing factors, treatment and follow-up.
    RESULTS: 21 patients were included, 5 patients (24%) were 30 years old at diagnosis, 12 (57%) patients were aged 20-29 years and 4 patients (19%) were less than 20 years old. Thirteen of the 21 patients were female, and 8 (38%) were male, 6 of the 21 patients (29%) were Malaysian, while 1 was Indian (4%). The remainder were Chinese, 14 patients (67%). Six patients (29%) had their primary tumour located in the rectosigmoid, 4 (19%) in the left colon, 1 (4%) in the splenic flexure, 2 in the transverse colon (9%), 1 in the hepatic flexure (4%) and 5 in the caecum 24(%). One patient had a tumour too diffuse to detect a primary site at the time of operation. One patient with a family history of polyps had his entire colon removed at age 14. He had 3 separate foci of tumour. The 5-year survival rate was 25%.
    DISCUSSION: Most patients with extensive disease and mucinous histology. Lesions are commonly seen beyond the transverse colon (57%). Presentation included most commonly abdominal pain, haematochezia or haemoccult positive stools.
    CONCLUSION: The symptoms above should alert surgeons to colorectal carcinoma as a differential diagnosis

    BACKGROUND: Bleeding is a common complication associated with percutaneous coronary intervention (PCI). The aim of this study was to determine the prevalence of bleeding after PCI through a systematic review and meta-analysis.

    METHODS: The systematic review and meta-analysis covered the period from 1989 to 2023. Multiple databases, including Embase, PubMed, Scopus, Web of Sciences (WoS), MagIran, Scientific Information Database (SID), and Google Scholar, were searched using validated keywords with MeSH and Emtree. The I2 index was used to check for heterogeneity among studies.

    RESULTS: The review of 8 studies, with a sample size of 397,298 participants, showed high heterogeneity (I2: 97.8 %). Therefore, the random effects method was used to analyze the results. The prevalence of bleeding after intervention in percutaneous coronary arteries was reported to be 4.4 % (95%CI: 2-9.1).

    CONCLUSION: This meta-analysis showed a significant prevalence of bleeding after PCI, highlighting the need for health policymakers to pay more attention to the complications associated with PCI. Interventional cardiologists should consider the effective factors in these bleeding and how to treat and control them due to the importance of this complication.

    Identifying the differences between infants with non-accidental head injuries (NAHI) and accidental head injuries (AHI) may help alert clinicians to recognize markers of abuse. A retrospective review of infants <1 year of age admitted to a tertiary referral centre in Malaysia over a two year period with a diagnosis of head injury or abnormal computed tomography head scans was conducted to identify the clinical features pointing towards a diagnosis of NAHI by comparing the socio-demographics, presenting complaints, clinical features and the extent of hospital investigations carried out. NAHI infants were more likely to be symptomatic, under a non-related caregiver's supervision, and presented with inconsistent or no known mechanism of injury. Subdural haemorrhages were more common in NAHI infants. The history, mechanism of injury, presenting signs and symptoms as well as the nature of the injuries sustained are all valuable clues as to whether a head injury sustained during infancy is likely to be accidental or not.

    BACKGROUNDS: Limited evidence is available regarding pharmacist managed anticoagulation clinic in the Southeast Asian region where there is marked difference in terms of care model, genetic composition and patient demographics.

    OBJECTIVES: This study aimed at comparing the anticoagulation clinic managed by the pharmacist with physician advisory and the usual medical care provided in Kuala Lumpur Hospital (KLH) in terms of anticoagulation control and adverse outcomes.

    SETTING: A 2,302 bedded government tertiary referral hospital in Malaysia.

    METHODS: A 6-month retrospective cohort study of the effectiveness of two models of anticoagulation care, the pharmacist managed anticoagulation clinic which is known as warfarin medication therapy adherence clinic (WMTAC) and usual medical clinic (UMC) in KLH was conducted, where a random number generator was used to recruit patients. The UMC patients received standard medical care where they are managed by rotational medical officers in the physicians' clinic. As for the WMTAC with physician advisory, the pharmacist will counsel and review the patients internationalised normalization ratio at each clinic visit and also adjust the patients' warfarin dose accordingly. Patients are referred to physicians if immediate attention is required.

    MAIN OUTCOME MEASURE: The main therapeutic outcome is time in therapeutic range (TTR) both actual and expanded TTR and thromboembolic and bleeding complications.

    RESULTS: Each of the WMTAC and usual medical care recruited 92 patients, which totals to 184 patients. The patient demographics in terms of age, race and indication of treatment were comparable. At the end of the 6 months follow-up, patients in the WMTAC group had significantly higher actual-TTR (65.1 vs. 48.3 %; p < 0.05) compared to those in usual medical care group. Rates of admission were 6.5 versus 28.2 events per 100 person-years for the WMTAC and UMC groups, respectively. Though the bleeding incidences were not significantly different, it was reduced.

    CONCLUSIONS: These findings will impact local warfarin patient management services and policies because there was no available evidence supporting the role of pharmacists in the management of warfarin patients prior to this study.

    Background Oral anticoagulant therapy is indicated for the prevention of stroke or other thromboembolic events. Premature discontinuation of oral anticoagulants may increase the risk of thromboembolism resulting in adverse sequelae. There are sparse data on the prevalence and the predictors of dabigatran discontinuation in Malaysian patients with atrial fibrillation. Objectives Determine the reasons and identify associated factors for abrupt discontinuation of dabigatran, assess the switching pattern and the occurrence of thromboembolic events after dabigatran discontinuation. Setting A university-affiliated tertiary hospital in Kuala Lumpur, Malaysia. Methods The clinical and demographic data of a cohort who were initiated with dabigatran between 2010 and 2012 at the University of Malaya Medical Centre were reviewed until the date of death or on 31st December 2013. Those patients who discontinued dabigatran were further followed up until 31st December 2015 to determine the occurrence of any thromboembolic event. Main outcome measure Permanent discontinuation of dabigatran for more than 8 weeks. Results 26 (14 %) of a cohort of 192 patients discontinued dabigatran therapy during a median follow-up period of 20 (range 3-45) months. About one-half of the discontinuation occurred within the first 6 months of dabigatran use. The three most cited reasons for discontinuation are bleeding events (19 %), high out-of-pocket drug payment (19 %) and cardioversion (19 %). Heart failure [adjusted odds ratio 3.699 (95 % confidence interval 1.393-9.574)] or chronic kidney disease [adjusted odds ratio 5.211 (95 % confidence interval 1.068-23.475)] were found to be independent risk factors for abrupt dabigatran discontinuation. Patients who discontinued dabigatran received warfarin (38 %), antiplatelet agents (16 %) or no alternative antithrombotic therapy (46 %). Five of the 26 patients who discontinued dabigatran developed an ischaemic stroke within 3-34 months after discontinuation. Conclusion Abrupt dabigatran discontinuation without an alternative oral anticoagulant increases the risk of thromboembolic events. As adverse drug events and renal impairment contribute substantially to the premature discontinuation of dabigatran, it is important to identify and monitor patients at risk to reduce dabigatran discontinuation rate especially during the first six months of dabigatran therapy.

    OBJECTIVE:
    To evaluate the 50-g glucose challenge test (GCT) on pregnancy outcome in a multiethnic Asian population at high risk for gestational diabetes (GDM).

    METHODS:
    GCT was positive if the 1-hour plasma glucose level was >or=7.2 mmol/L. GDM was diagnosed by a 75-g glucose tolerance test using WHO (1999) criteria. Of the 1368 women enrolled in the study, 892 were GCT negative, 308 were GCT false-positive, and 168 had GDM. Pregnancy outcomes were extracted from hospital records. Multivariable logistic regression analysis was performed with GCT negative women as the reference group.

    RESULTS:
    GCT false-positive status was associated with preterm birth (adjusted odds ratio [AOR] 2.1; 95% CI, 1.2-3.7) and postpartum hemorrhage (AOR 1.7; 95% CI, 1.0-2.7). GDM was associated with labor induction (AOR 5.0; 95% CI, 3.3-7.5), cesarean delivery (AOR 2.2; 95% CI, 1.6-3.2), postpartum hemorrhage (AOR 2.1; 95% CI, 1.2-3.7), and neonatal macrosomia (AOR 2.5; 95% CI, 1.0-6.0).

    CONCLUSION:
    GCT false-positive women had an increased likelihood of an adverse pregnancy outcome. The role and threshold of the GCT needs re-evaluation.

    Trends in selected pregnancy complications from 1969 to 1987 in a tertiary hospital in Malaysia are presented. Complications reviewed were abortion, ectopic pregnancy, anemia, hypertension, hyperemesis, antepartum and postpartum hemorrhage. Possible explanations for the observed trends were discussed, including the role of improved obstetric care and changes in the characteristics of the childbearing population. The data presented give some indication of maternal morbidity in the childbearing population served by this tertiary center and should lead to improvements in provision of services as well as in health data collection in the future.

    BACKGROUND: Low level of fibrinogen is a risk factor of perioperative bleeding, which is a major complication in surgical patients. However, the safety and efficacy of fibrinogen supplementation with fibrinogen concentrate to minimize postoperative bleeding remains unclear.

    OBJECTIVES: The primary aim of this review was to investigate the effect of fibrinogen concentrate in postoperative blood loss in adult surgical patients.

    DESIGN: Systematic review and meta-analysis.

    DATA SOURCES: Databases of MEDLINE, EMBASE and CENTRAL were searched from their start date until July 2019.

    ELIGIBILITY CRITERIA: All randomized clinical trials comparing intravenous fibrinogen concentrate and placebo in adult surgical patients were included, regardless of type of surgery. Observational studies, case reports, case series and non-systematic reviews were excluded.

    RESULTS: Thirteen trials (n = 900) were included in this review. In comparison to placebo, fibrinogen concentrate significantly reduced the first 12-hour postoperative blood loss, with a mean difference of -134.6 ml (95% CI -181.9 to -87.4). It also significantly increased clot firmness in thromboelastometry (FIBTEM) with a mean difference of 2.5 mm (95%CI 1.1 to 3.8). No significant differences were demonstrated in the adverse events associated with fibrinogen concentrate use, namely incidence of thromboembolism, myocardial infarction and acute kidney injury.

    CONCLUSIONS: In this meta-analysis of 13 randomized trials, low level of evidence and substantial heterogeneity with small sample size limit strong recommendation on the use of fibrinogen concentrate in adult surgical patients. However, its use is tolerable without any notable adverse events.

    TRIAL REGISTRATION: CRD42019149164.
