RESUMEN
INTRODUCTION: Patients receiving methadone maintenance therapy (MMT) experience higher level of stress and are at greater risk of developing mental health problems such as depression which could potentially affect both quality of life and treatment outcomes. This cross-sectional study is aimed at understanding the relationship between psychosocial factors such as social support, coping, and depression among patients receiving MMT in a Malaysian Hospital. METHODS: One hundred and ninety-six patients attending MMT program were recruited. The Patient Health Questionnaire-9 (PHQ-9) was used to screen for depression, Multidimensional Scale of Perceived Social Support (MSPSS) was used to assess participants' perceived social support, and the Brief COPE questionnaire was used to assess coping strategies. The diagnosis of depression was made using Mini-International Neuropsychiatric Interview (MINI). RESULTS: About 13.8% of our sample were diagnosed with depression. From our analysis, it was found that having higher levels of perceived social support (OR = 0.462, 95% CI 0.238-0.899, P < .05), the use of active and emotion focused coping mechanism (OR = 0.231, 95% CI 0.095-0.565, P < .005), and support seeking and self-distraction coping mechanism (OR = 0.196, 95% CI 0.074-0.521, P < .001) was associated with lower likelihood of depression. On the contrary, the use of dysfunctional coping strategies such as denial, behavioral disengagement, and self-blame was associated with increased likelihood of depression (OR = 9.384, 95% CI 3.081-28.581, P < .001). CONCLUSION: Active and emotion focused along with support and self-distraction coping strategies, and higher levels of perceived social support may serve as a buffer against depression in patients receiving MMT.
RESUMEN
IntroductionAs of 3rd June 2021, Malaysia is experiencing a resurgence of COVID-19 cases. In response, the federal government has implemented various non-pharmaceutical interventions (NPIs) under a series of Movement Control Orders and, more recently, a vaccination campaign to regain epidemic control. In this study, we assessed the potential for the vaccination campaign to control the epidemic in Malaysia and four high-burden regions of interest, under various public health response scenarios. MethodsA modified susceptible-exposed-infectious-recovered compartmental model was developed that included two sequential incubation and infectious periods, with stratification by clinical state. The model was further stratified by age and incorporated population mobility to capture NPIs and micro-distancing (behaviour changes not captured through population mobility). Emerging variants of concern (VoC) were included as an additional strain competing with the existing wild-type strain. Several scenarios that included different vaccination strategies (i.e. vaccines that reduce disease severity and/or prevent infection, vaccination coverage) and mobility restrictions were implemented. ResultsThe national model and the regional models all fit well to notification data but underestimated ICU occupancy and deaths in recent weeks, which may be attributable to increased severity of VoC or saturation of case detection. However, the true case detection proportion showed wide credible intervals, highlighting incomplete understanding of the true epidemic size. The scenario projections suggested that under current vaccination rates complete relaxation of all NPIs would trigger a major epidemic. The results emphasise the importance of micro-distancing, maintaining mobility restrictions during vaccination roll-out and accelerating the pace of vaccination for future control. Malaysia is particularly susceptible to a major COVID-19 resurgence resulting from its limited population immunity due to the countrys historical success in maintaining control throughout much of 2020.
RESUMEN
Background@#With the emergence of tyrosine kinase inhibitors and the incorporation of stringent measurable residual disease (MRD) monitoring, risk stratification for BCR-ABL1-positive acute lymphoblastic leukemia (ALL) patients has changed significantly. However, whether this monitoring can replace conventional risk factors in determining whether patients need allogeneic stem cell transplantation is still unclear. This study aimed to determine the impact of BCR-ABL1 monitoring on the outcome of patients with BCR-ABL1-positive ALL after allogeneic stem cell transplantation. @*Methods@#We retrospectively analyzed the survival outcome of patients with BCR-ABL1-positive ALL based on the quantification of BCR-ABL1 at 3 timepoints: the end of induction (timepoint 1), post-consolidation week 16 (timepoint 2), and the end of treatment for patients who were either transplant-eligible or non-transplant eligible (timepoint 3). @*Results@#From 2006 to 2018, a total of 96 patients newly diagnosed with BCR-ABL1-positive ALL were treated with chemotherapy and tyrosine kinase inhibitors. Thirty-eight (41.3%) patients achieved complete remission, and 33 patients underwent allogeneic stem cell transplantation. Our data showed that pre-transplant MRD monitoring by real-time quantitative polymerase chain reaction had the highest correlation with survival in patients with BCR-ABL1-positive ALL, especially for those who underwent allogeneic stem cell transplantation. @*Conclusion@#Patients without MRD pre-transplantation had superior survival compared with those who had MRD, and they had excellent long-term outcomes after allogeneic stem cell transplantation.

RESUMEN
BACKGROUND: Thrombotic microangiopathy (TMA) with non-deficient ADAMTS-13 (a disintegrin-like and metalloprotease with thrombospondin type 1 motif 13) outcome is unknown hence the survival analysis correlating with ADAMTS-13 activity is conducted in Malaysia. METHODS: This was a retrospective epidemiological study involving all cases of TMA from 2012–2016. RESULTS: We evaluated 243 patients with a median age of 34.2 years; 57.6% were female. Majority of the patients were Malay (62.5%), followed by Chinese (23.5%) and Indian (8.6%). The proportion of patients with thrombotic thrombocytopenic purpura (TTP) was 20.9%, 72.2% of which were acquired while 27.8% were congenital. Patients with ADAMTS-13 activity ≥5% had a four-fold higher odds of mortality compared to those with ADAMTS-13 activity <5% (odds ratio: 4.133, P=0.0425). The mortality rate was 22.6% (N=55). Most cases had secondary etiologies (42.5%), followed by acquired TTP (16.6%), atypical hemolytic uremic syndrome (HUS) or HUS (12.8%) and congenital TTP (6.4%). Patients with secondary TMA had inferior overall survival (P=0.0387). The secondary causes comprised systemic lupus erythematosus (30%), infection (29%), pregnancy (10%), transplant (8%), malignancy (6%), and drugs (3%). Transplant-associated TMA had the worst OS (P=0.0016) among the secondary causes. Plasma exchange, methylprednisolone and intravenous immunoglobulin were recorded as first-line treatments in 162 patients, while rituximab, bortezomib, vincristine, azathioprine, cyclophosphamide, cyclosporine, and tacrolimus were described in 78 patients as second-line treatment. CONCLUSION: This study showed that TMA without ADAMTS-13 deficiency yielded inferior outcomes compared to TMA with severeADAMTS-13 deficiency, although this difference was not statistically significant.
