Background
In Malaysia, compulsory drug detention centres (CDDCs) hold suspected drug users for two years without adjudication. Acute detoxification without healthcare access has been documented. CDDCs are criticized globally due to ineffectiveness in treating addiction and human rights violations. In response, the Malaysian government began transitioning these facilities into voluntary drug treatment centres known as “Cure and Care” (C&C) centres that embrace a holistic treatment-based approach to drug addiction rehabilitation.
Methods
An explorative qualitative study was undertaken to explore patient perspectives and satisfaction regarding treatment and services at the new Cure and Care centre in Kota Bharu, Malaysia. A convenience sample of 20 patients was recruited to participate in semi-structured in-depth interviews. Content analysis approach was used to identify the salient themes.
Results
Patients identified methadone treatment, psychosocial programs, religious instruction, and recreational activities as important factors contributing to treatment success for addressing both health and addiction needs. Though many had previously been in a CDDC, adherence to treatment in the C&C centre was perceived to be facilitated by the degree of social support, the voluntary nature and the array of new programs available for selection.
Conclusion
C&Cs represents a dramatic shift in the Malaysian government’s approach to drug addiction. Our findings demonstrate positive patient experiences associated with the holistic treatment-based approach of these centres. This exploratory study provides additional evidence to document this ongoing policy transition and may guide continued expansion of new holistic drug treatment programs across the country.
The increasing demand for novel biocatalysts stimulates exploration of resources from soil. Metagenomics, a culture independent approach, represent a sheer unlimited resource for discovery of novel biocatalysts from uncultured microorganisms. In this study, a soil-derived metagenomic library containing 90,700 recombinants was constructed and screened for lipase, cellulase, protease and amylase activity. A gene (pAMY) of 909 bp encoding for amylase was found after the screening of 35,000 Escherichia coli clones. Amino acid sequence comparison and phylogenetic analysis indicated that pAMY was closely related to uncultured bacteria. The molecular mass of pAMY was estimated about 38 kDa by sodium dodecyl sulphate polyacrylamide gel electrophoresis. Amylase activity was determined using soluble starch, amylose, glycogen and maltose as substrates. The maximal activity (2.46 U/mg) was observed at 40 degrees C under nearly neutral pH conditions with amylose; whereas it retains 90% of its activity at low temperature with all the substrates used in this study. The ability of pAMY to work at low temperature is unique for amylases reported so far from microbes of cultured and uncultured division.
Background
As part of an ongoing initiative by the Malaysian government to implement alternative approaches to involuntary detention of people who use drugs, the National Anti-Drug Agency has created new voluntary drug treatment programs known as Cure and Care (C&C) Centers that provide free access to addiction treatment services, including methadone maintenance therapy, integrated with social and health services.
Objectives
We evaluated early treatment outcomes and client satisfaction among patients accessing C&C treatment and ancillary services at Malaysia’s second C&C Center located in Kota Bharu, Kelantan.
Methods
In June–July 2012, a cross-sectional convenience survey of 96 C&C inpatients and outpatients who entered treatment >30 days previously was conducted to assess drug use, criminal justice experience, medical co-morbidities, motivation for seeking treatment, and attitudes towards the C&C. Drug use was compared for the 30-day-period before C&C entry and the 30-day-period before the interview.
Results
Self-reported drug use levels decreased significantly among both inpatient and outpatient clients after enrolling in C&C treatment. Higher levels of past drug use, lower levels of social support, and more severe mental health issues were reported by participants who were previously imprisoned. Self-reported satisfaction with C&C treatment services was high.
Conclusions/Importance
Preliminary evidence of reduced drug use and high levels of client satisfaction among C&C clients provide support for Malaysia’s ongoing transition from compulsory drug detention centers (CDDCs) to these voluntary drug treatment centers. If C&C centers are successful, Malaysia plans to gradually transition away from CDDCs entirely.
Background
Drug use in Malaysia remains a significant public health and social problem despite implementation of harsh punitive drug policies such as forcibly placing suspected drug users into compulsory drug detention centers (CDDCs). Following criticism over human right violations in CDDCs, Malaysia has begun to transition towards voluntary drug treatment centers known as Cure & Care (C&C) Centers. To best serve the needs of regional C&Cs, data on drug use are essential among patients accessing treatment. Using a mixed methods approach, we examined pre-treatment drug use characteristics and experiences with addiction treatment among C&C patients in Kelantan – a religiously conservative state in Northeast Malaysia with high prevalence of drug use but where limited data are available on drug use patterns.
Methods
A mixed methods study utilizing surveys (N=96) and semi-structured interviews (N=20) was conducted among a convenience sample of inpatients and outpatients at the Pengkalan Chepa C&C Center in Kelantan.
Results
Survey results showed 89.6% of participants met screening criteria for moderate to severe addiction severity. Nearly 90% reported lifetime illicit amphetamine (syabu, meth, ice, and pil kuda) use followed by alcohol (60.4%) and opioids (52.1%). Qualitative results pointed to the powerful influence of peer networks in drug initiation and relapse, and the positive effect of the C&C on drug rehabilitation.
Conclusions
The drug use profile of the Kelantan C&C enrollees shows extensive pre-treatment amphetamine use, polysubstance use, and injection drug use including high-risk behaviors such as sharing needles, syringes and containers. Evidence points to the need for integration of social support-oriented practices and behavioral interventions into the rehabilitation of drug users in this region.
Mycobacterium tuberculosis bacteria cause deadly infections in patients [Corrected]. The rise of multidrug resistance associated with tuberculosis further makes the situation worse in treating the disease. M. tuberculosis proteasome is necessary for the pathogenesis of the bacterium validated as an anti-tubercular target, thus making it an attractive enzyme for designing Mtb inhibitors. In this study, a computational screening approach was applied to identify new proteasome inhibitor candidates from a library of 50,000 compounds. This chemical library was procured from the ChemBridge (20,000 compounds) and the ChemDiv (30,000 compounds) databases. After a detailed analysis of the computational screening results, 50 in silico hits were retrieved and tested in vitro finding 15 compounds with IC₅₀ values ranging from 35.32 to 64.15 μM on lysate. A structural analysis of these hits revealed that 14 of these compounds probably have non-covalent mode of binding to the target and have not reported for anti-tubercular or anti-proteasome activity. The binding interactions of all the 14 protein-inhibitor complexes were analyzed using molecular docking studies. Further, molecular dynamics simulations of the protein in complex with the two most promising hits were carried out so as to identify the key interactions and validate the structural stability.
The archaeal diversity in salt pan sediment from Mumbai, India, was investigated by 16S rDNA-dependent molecular phylogeny. Small-subunit rRNA (16S rDNA) from salt pan sediment metagenome were amplified by polymerase chain reaction (PCR) using primers specific to the domain archaea. Thirty-two unique phylotypes were obtained by PCR-based RFLP of 16S rRNA genes using endonucleases Hae111 and Msp1, which were most suitable to score the genetic diversity. These phylotypes spanned a wide range within the domain Archaea including both Crenarchaeota and Euryarcheaota. However, none of the retrieved Crenarchaeota sequences could be grouped with previously cultured Crenarchaeota. Of all the Euryarcheaota sequences, three sequences were related to Haloarchaea, two were related to cultured Methanosarcina sp., and the remaining sequences were affiliated with uncultured Methanosarcina sp., Methanogenium sp., and Methanolobus sp. Most of the sequences determined were closely related to the sequences that had been previously obtained from metagenome of a variety of marine environments. The phylogenetic study of a site investigated for the first time revealed the presence of a highly diverse archaeal population and may represent novel sequences and organisms specially adapted to the salt pan sediment of Mumbai. These findings are of fundamental value for understanding the complexity of salt pan ecosystems.
