    BACKGROUND: Research into capital punishment has focussed on the length of time it will take to abolish. It will take decades or centuries. A key moment in the movement to abolish the death penalty was the 1980s when the Second Optional Protocol to the ICCPR was developed. This was also the decade that the last significant changes were made to the United Nations drug conventions. At the time, awareness of the issue of capital punishment for drug offences was increasing around the world as more people were getting executed. This article looks at how western countries and the United Nations responded to Malaysia which introduced the mandatory death penalty for drug offences in 1982.

    METHODS: Over 30,000 pages of documents have been accessed through the National Archives of Australia in Canberra. These have been photographed, scanned and converted to OCR. The most relevant folders have then been analysed through NVivo 12 to look for relevant mentions of the research question: capital punishment and Malaysia. All probative data is then presented in the article.

    RESULTS: The data from National Archives suggests that the UN, Australia, and other western countries were happy to continue supporting Malaysia's drug policy and to elect it to high positions at UN meetings despite their public proclamations that they were opposed to the death penalty.

    CONCLUSION: Applying a critical juncture approach, the article concludes that the 1980s was a critical juncture in the movement to abolish the death penalty but abolitionist countries allowed capital punishment to continue for drug offences. This may have set back the abolition movement by decades.

    Osteoarthritis (OA) is a chronic degenerative joint disorder associated with degradation and decreased production of the extracellular matrix, eventually leading to cartilage destruction. Limited chondrocyte turnover, structural damage, and prevailing inflammatory milieu prevent efficient cartilage repair and restoration of joint function. In the present study, we evaluated the role of secreted cytokines, chemokines, and growth factors present in the culture supernatant obtained from an ex vivo osteochondral model of cartilage differentiation using cartilage pellets (CP), bone marrow stem cells (BM-MSCs), and/or BM-MSCs + CP. Multiplex cytokine analysis showed differential secretion of growth factors (G-CSF, GM-CSF, HGF, EGF, VEGF); chemokines (MCP-1, MIP1α, MIP1β, RANTES, Eotaxin, IP-10), pro-inflammatory cytokines (IL-1β, IL-2, IL-5, IL-6, IL-8, TNFα, IL-12, IL-15, IL-17) and anti-inflammatory cytokines (IL-4, IL-10, and IL-13) in the experimental groups compared to the control. In silico analyses of the role of stem cells and CP in relation to the expression of various molecules, canonical pathways and hierarchical cluster patterns were deduced using the Ingenuity Pathway Analysis (IPA) software (Qiagen, United States). The interactions of the cytokines, chemokines, and growth factors that are involved in the cartilage differentiation showed that stem cells, when used together with CP, bring about a favorable cell signaling that supports cartilage differentiation and additionally helps to attenuate inflammatory cytokines and further downstream disease-associated pro-inflammatory pathways. Hence, the autologous or allogeneic stem cells and local cartilage tissues may be used for efficient cartilage differentiation and the management of OA.

    PURPOSE: We compared demographic and clinical characteristics of the University of Sciences Malaysia Chronic Prostatitis Cohort to the United States National Institutes of Health Chronic Prostatitis Cohort.
    MATERIALS AND METHODS: Participants met the same definition of chronic prostatitis/chronic pelvic pain syndrome. Each participant had extensive demographic, medical history, previous treatment, clinical and laboratory evaluations.
    RESULTS: The University of Sciences Malaysia and National Institutes of Health cohorts proved similar in most respects. National Institutes of Health-Chronic Prostatitis Symptom Index total scores, pain and urinary subscores were similar for the 332 University of Sciences Malaysia Chronic Prostatitis Cohort and 488 National Institutes of Health Chronic Prostatitis Cohort participants. Differences included worse quality of life subscore for the University of Sciences Malaysia Chronic Prostatitis Cohort, differences in the location, number of sites, and types of pain/discomfort between the 2 populations, and that the University of Sciences Malaysia participants had received less previous treatment.
    CONCLUSIONS: The demographic characteristics and clinical presentation of chronic prostatitis/chronic pelvic pain syndrome proved remarkably similar in these diverse populations. Both cohorts experienced major reduction in their quality of life from chronic pelvic pain and urinary symptoms. Comparison of diverse populations using standard clinical, laboratory and assessment instruments is feasible, and may provide important insights into chronic prostatitis/chronic pelvic pain syndrome and the factors that determine clinical outcome.

    CONTEXT: To investigate the antibiotic prescribing training received by dental students, clinical experience in treating child patients, awareness of antibiotic prescribing guidelines, preparedness in antibiotic prescribing, and compliance with antibiotic prescribing guidelines for the management of dental infections in children.
    METHODS: This was a cross-sectional study involving final year dental students from Malaysian and Asian dental schools. A self-administered questionnaire consisting of five clinical case scenarios was e-mailed to all final year students at selected dental schools. Students' responses were compared for each clinical case scenario with the prescribing guidelines of the American Academy of Pediatric Dentistry and the American Dental Association. Compliance in each scenario was tested for association with their preparedness in antibiotic prescribing, previous training on antibiotic prescribing and awareness of antibiotic prescribing guidelines using Chi-square test. Data collected were analyzed using SPSS statistics version 20.
    RESULTS: A total of 108 completed responses were received. About 74 (69%) students were from Malaysian dental schools. The compliance rate with prescribing guidelines ranged from 15.7% to 43.5%. Those attending Malaysian dental schools (47.3%) and those who had treated child patient more often (46.3%) were more likely (P < 0.05) to be aware of the guidelines. Those who had received antibiotic prescribing training (21.3%) were more likely to think they were well prepared in antibiotic prescribing (P < 0.05).
    CONCLUSIONS: Final year dental students had low awareness and compliance with antibiotic prescribing guidelines. Further research is needed to investigate how compliance with the guidelines may be enhanced.

    The design of family studies to estimate the value of an intraclass correlation coefficient p is considered when ni individuals are to be selected from each of k families, i = 1, 2, ..., k. In particular, the accuracy of a balance design (ni = n, i = 1, 2, ..., k) for estimating p is compared with the accuracy of an unbalanced "natural" design, in which the ni are sampled at random from family size distributions that tend to occur in practice. It is found for two different estimators of p that the balanced design is usually preferable, but only to a small degree if the number of families sampled is greater than 50.

    We investigate the role of military expenditure on emission in USA during the period 1960-2015. To achieve the objectives of this study, two measures of military expenditure are utilised, while several timeseries models are constructed with the gross domestic product (GDP) per capita, population, energy consumption per capita, non-renewable energy consumption per capita, renewable energy consumption per capita, urbanisation, trade openness and financial development serving as additional determinants of air pollution. We also use ecological indicator as an alternative measure of pollution. Moreover, different timeseries methods are utilised including a likelihood-based approach with two structural breaks. The output of this research concluded that all the variables are cointegrated. It is found that military expenditure has mixed impact on CO2 emissions. Real GDP per capita, energy consumption per capita, non-renewable energy consumption per capita, population and urbanisation increase CO2 emissions per capita in the long-run, while renewable energy consumption, financial development and trade openness reduce it. There is also evidence for the mixed role of military expenditure, when ecological footprint is utilised as the environmental degradation index. From the output of this research, few policy recommendations are offered for the examined country.

    Background: The Kidd (JK) blood group system is of clinical importance in transfusion medicine. JK*A and JK*B allele detections are useful in genetic anthropological studies. This study aimed to determine the frequencies of JK*A and JK*B alleles among Muslim blood donors from Southern Thailand and to compare how they differ from those of other populations that have been recently studied.

    Methods: A cross-sectional study was used. Totally, 427 samples of dissimilar Thai-Muslim healthy blood donors living in three southern border provinces were selected via simple random sampling (aged 17-65 years old) and donors found to be positive for infectious markers were excluded. All samples were analysed for JK*A and JK*B alleles using PCR-SSP. The Pearson's chi-squared and Fisher exact tests were used to compare the JK frequencies among southern Thai-Muslim with those among other populations previously reported.

    Results: A total of 427 donors-315 males and 112 females, with a median age of 29 years (interquartile range: 18 years)-were analysed. A JK*A/JK*B genotype was the most common, and the JK*A and JK*B allele frequencies among the southern Thai-Muslims were 55.2% and 44.8%, respectively. Their frequencies significantly differed from those of the central Thai, Korean, Japanese, Brazilian-Japanese, Chinese, Filipino, Africans and American Natives populations (P < 0.05). Predicted JK phenotypes were compared with different groups of Malaysians. The Jk(a+b+) phenotype frequency among southern Thai-Muslims was significantly higher than that of Malaysian Malays and Indians (P < 0.05).

    Conclusions: The JK*A and JK*B allele frequencies in a southern Thai-Muslim population were determined, which can be applied not only to solve problems in transfusion medicine but also to provide tools for genetic anthropology and population studies.

    Introduction: Most neurophysiology departments around the world establish their own normative data. However, ethnic differences are not taken into account. Our aim was to establish normal nerve conduction studies (NCS) data for routinely tested nerves in individuals of Pakistani (South Asian) origin and to compare with Western published data.

    Materials and Methods: One hundred healthy adults' nerves were assessed, using standardized techniques. Individuals were grouped into age groups. Gender differences were assessed.

    Results: Of the 100 volunteers, 49 were female and 51 were male. Their mean age was 39.8 years. Findings showed statistically significant prolongation of median distal motor latency (DML) and F-wave latency with age and reduction of median, ulnar, and sural sensory amplitudes as age increased. Gender differences showed consistent difference in the normal values for median, ulnar, and peroneal DMLs and respective F-wave latencies, which were significantly shorter in females. Sensory amplitudes of tested upper extremity nerves were significantly lower in males. Comparing with available data, our findings are similar to the Saudi population but significantly different from the American and multiethnic Malaysian populations. Pakistani individuals generally have significantly higher amplitudes and faster conduction velocities with similarities to South Asian studies.

    Conclusions: We recommend normative NCS parameters for commonly tested nerves for the Pakistani population, using standardized techniques to ensure highest quality testing and outcomes.

    BACKGROUND: El Niño/Southern Oscillation (ENSO) related climate anomalies have been shown to have an impact on infectious disease outbreaks. The Climate Prediction Center of the National Oceanic and Atmospheric Administration (NOAA/CPC) has recently issued an unscheduled El Niño advisory, indicating that warmer than normal sea surface temperatures across the equatorial eastern Pacific may have pronounced impacts on global tropical precipitation patterns extending into the northern hemisphere particularly over North America. Building evidence of the links between ENSO driven climate anomalies and infectious diseases, particularly those transmitted by insects, can allow us to provide improved long range forecasts of an epidemic or epizootic. We describe developing climate anomalies that suggest potential disease risks using satellite generated data.

    RESULTS: Sea surface temperatures (SSTs) in the equatorial east Pacific ocean have anomalously increased significantly during July - October 2006 indicating the typical development of El Niño conditions. The persistence of these conditions will lead to extremes in global-scale climate anomalies as has been observed during similar conditions in the past. Positive Outgoing Longwave Radiation (OLR) anomalies, indicative of severe drought conditions, have been observed across all of Indonesia, Malaysia and most of the Philippines, which are usually the first areas to experience ENSO-related impacts. This dryness can be expected to continue, on average, for the remainder of 2006 continuing into the early part of 2007. During the period November 2006 - January 2007 climate forecasts indicate that there is a high probability for above normal rainfall in the central and eastern equatorial Pacific Islands, the Korean Peninsula, the U.S. Gulf Coast and Florida, northern South America and equatorial east Africa. Taking into consideration current observations and climate forecast information, indications are that the following regions are at increased risk for disease outbreaks: Indonesia, Malaysia, Thailand and most of the southeast Asia Islands for increased dengue fever transmission and increased respiratory illness; Coastal Peru, Ecuador, Venezuela, and Colombia for increased risk of malaria; Bangladesh and coastal India for elevated risk of cholera; East Africa for increased risk of a Rift Valley fever outbreak and elevated malaria; southwest USA for increased risk for hantavirus pulmonary syndrome and plague; southern California for increased West Nile virus transmission; and northeast Brazil for increased dengue fever and respiratory illness.

    CONCLUSION: The current development of El Niño conditions has significant implications for global public health. Extremes in climate events with above normal rainfall and flooding in some regions and extended drought periods in other regions will occur. Forecasting disease is critical for timely and efficient planning of operational control programs. In this paper we describe developing global climate anomalies that suggest potential disease risks that will give decision makers additional tools to make rational judgments concerning implementation of disease prevention and mitigation strategies.

    Some chemicals in the environment possess the potential to interact with the endocrine system in the human body. Multiple receptors are involved in the endocrine system; estrogen receptor α (ERα) plays very important roles in endocrine activity and is the most studied receptor. Understanding and predicting estrogenic activity of chemicals facilitates the evaluation of their endocrine activity. Hence, we have developed a decision forest classification model to predict chemical binding to ERα using a large training data set of 3308 chemicals obtained from the U.S. Food and Drug Administration's Estrogenic Activity Database. We tested the model using cross validations and external data sets of 1641 chemicals obtained from the U.S. Environmental Protection Agency's ToxCast project. The model showed good performance in both internal (92% accuracy) and external validations (∼ 70-89% relative balanced accuracies), where the latter involved the validations of the model across different ER pathway-related assays in ToxCast. The important features that contribute to the prediction ability of the model were identified through informative descriptor analysis and were related to current knowledge of ER binding. Prediction confidence analysis revealed that the model had both high prediction confidence and accuracy for most predicted chemicals. The results demonstrated that the model constructed based on the large training data set is more accurate and robust for predicting ER binding of chemicals than the published models that have been developed using much smaller data sets. The model could be useful for the evaluation of ERα-mediated endocrine activity potential of environmental chemicals.

    Objectives: There is little evidence in the medical literature about safety of PDA device closure and its effects on aortic root diameter in Marfan patients. We reported on nine Marfan patients whose ducts were occluded by coil or Amplatzer Duct Occluder.
    Patients and interventions: Two patients had aneurismal type E ducts which were closed by a single coil, respectively. The others had conical ducts for which even Amplatzer occluder, stiff, or double coils were used.
    Results: No untoward consequence was found during a median follow up period of 18.5 months (range 3 months to 6.33 years). Two patients had small residual shunts. The observed change in the mean ratio of aortic root diameter to its estimated value was statistically insignificant in seven patients who had complete data on their aortic root diameter before PDA closure and during the follow up.
    Conclusions: We concluded that PDA device closure in Marfan patients is safe. Risk of residual shunt is higher even after closure of small ducts.

    The prevalence of diabetes in Central America was somewhat greater than in East Pakistan and Malaya, less
    than in Uruguay and Venezuela, and substantially less than in affluent societies such as the United States. Differences in prevalence among Central American countries were modest but probably significant in some instances. In all Central American countries diabetes was more common in females but this difference was probably attributable to the greater adiposity of the women. Age-matched populations from eleven different countries of three continents have now been tested using standardized methods. Prevalence of diabetes varied greatly, and differences were more related to environment than to race. These results support the hypothesis that environmental factors can increase or reduce prevalence by several-fold.

    This article examines the fat and fibre intakes of Malaysian adults and highlights discrepancies and practical limitations if these intakes are to match the levels for these nutrients advocated in the World Health Organisation (WHO) and American Heart Association (AHA) ‘diet models’. Local data on food consumption showed that the total fat intakes amongst Malaysian adults, contrary to common perception, were not high and the mean values obtained fell within the range of 40-66g or 22-26% kcal. As such, the dietary target of 30% kcal total fat or its intermediate target of 30-35% kcal, advocated by WHO and AHA mainly to address the problem of a high consumption of dietary fats in western populations, should not be adopted indiscriminately by Malaysians. Dietary fatty acid (FA) analysis by high performance liquid chromatography (HPLC) coupled with the use of food composition tables, showed that the typical Malaysian diet prepared with palm olein or palm olein-groundnut oil blends as cooking oil contained 3.2-4.0% kcal polyunsaturated fatty acids (PUFA), mainly as the w-6 linoleic acid, which is also the predominant essential fatty acid (EFA) in humans. This level of linoleic acid, with an ω-6/ ω--3 FA ratio approximating 10, is adequate for basal PUPA and EFA needs but fell short of the 4-10% kcal linoleic acid recommended by WHO (1993) to counter the effects of the cholesterol-raising saturated fatty acids (SFA). This raised upper limit of 10% kcal linoleic acid (previously 7% kcal), which equals the level of PUFA implied in the AHA diet model, appears unnecessarily high considering that the cholesterol-lowering potential of linoleic acid is maximum at about 6% kcal, while the health hazards associated with long-term high intakes of PUPA have never been completely dismissed. The new WHO lower limit for dietary linoleic acid (4% kcal) would have a controversial impact of raising the previous minimal 3% kcal EFA to above 4% kcal (linoleic + alpha-linolenic acids). Similarly, the WHO recommendation for total dietary fibre of 27-40g (equivalent to a daily combined intake of 400g of vegetables and fruits, 30g of which should come from pulses) appears at present, too high a dietary target for the average Malaysian adult whose habitual daily diet was estimated to contain about 180g of vegetables plus fruits, providing only about 13-16g total dietary fibre. Appropriately, an expert panel on Malaysian Dietary Guidelines has recommended instead, 20-30% kcal total fat containing 3-7% kcal PUFA, and 20-30g total dietary fibre for the local population.

    The cellulose synthase-like gene HvCslF6, which is essential for (1,3;1,4)-β-glucan biosynthesis in barley, collocates with quantitative trait loci (QTL) for grain (1,3;1,4)-β-glucan concentration in several populations, including CDC Bold × TR251. Here, an alanine-to-threonine substitution (caused by the only non-synonymous difference between the CDC Bold and TR251 HvCslF6 alleles) was mapped to a position within HvCSLF6 that seems unlikely to affect enzyme stability or function. Consistent with this, transient expression of full-length HvCslF6 cDNAs from CDC Bold and TR251 in Nicotianabenthamiana led to accumulation of similar amounts of (1,3;1,4)-β-glucan accumulation. Monitoring of HvCslF6 transcripts throughout grain development revealed a significant difference late in grain development (more than 30 days after pollination), with TR251 [the parent with higher grain (1,3;1,4)-β-glucan] exhibiting higher transcript levels than CDC Bold. A similar difference was observed between Beka and Logan, the parents of another population in which a QTL had been mapped in the HvCslF6 region. Sequencing of a putative promoter region of HvCslF6 revealed numerous polymorphisms between CDC Bold and TR251, but none between Beka and Logan. While the results of this work indicate that naturally occurring quantitative differences in (1,3;1,4)-β-glucan accumulation may be due to cis-regulated differences in HvCslF6 expression, these could not be attributed to any specific DNA sequence polymorphism. Nevertheless, information on HvCslF6 sequence polymorphism was used to develop molecular markers that could be used in barley breeding to select for the desired [low or high (1,3;1,4)-β-glucan] allele of the QTL.

    Kratom is a plant material exhibiting both analgesic and stimulant effects and is also forensically relevant since it is abused as a "legal high." It is regulated in several countries but not scheduled in the United States at the federal level. This study used inductively coupled plasma-mass spectrometry (ICP-MS) to measure the concentrations of 13 elements in 19 kratom samples obtained from an online distributor selling kratom, from Borneo, Malaysia, Indonesia, Thailand, and Vietnam, for the purpose of using the elements to discriminate among purported country of origin, "suborigin," and strain. Analysis of variance revealed statistical differences in concentrations of elements from each group, while discriminant function analysis (using leave-one-out classification) successfully classified kratom samples by their purported country of origin (100%), "suborigin," (100%), and strain (86%). Our method illustrates the possibility of utilizing ICP-MS for determination of commercially available kratom samples by purported origin, "subororign," or by product line.

    BACKGROUND: Meta-analyses have investigated associations between race and ethnicity and COVID-19 outcomes. However, there is uncertainty about these associations' existence, magnitude, and level of evidence. We, therefore, aimed to synthesize, quantify, and grade the strength of evidence of race and ethnicity and COVID-19 outcomes in the US.

    METHODS: In this umbrella review, we searched four databases (Pubmed, Embase, the Cochrane Database of Systematic Reviews, and Epistemonikos) from database inception to April 2022. The methodological quality of each meta-analysis was assessed using the Assessment of Multiple Systematic Reviews, version 2 (AMSTAR-2). The strength of evidence of the associations between race and ethnicity with outcomes was ranked according to established criteria as convincing, highly suggestive, suggestive, weak, or non-significant. The study protocol was registered with PROSPERO, CRD42022336805.

    RESULTS: Of 880 records screened, we selected seven meta-analyses for evidence synthesis, with 42 associations examined. Overall, 10 of 42 associations were statistically significant (p ≤ 0.05). Two associations were highly suggestive, two were suggestive, and two were weak, whereas the remaining 32 associations were non-significant. The risk of COVID-19 infection was higher in Black individuals compared to White individuals (risk ratio, 2.08, 95% Confidence Interval (CI), 1.60-2.71), which was supported by highly suggestive evidence; with the conservative estimates from the sensitivity analyses, this association remained suggestive. Among those infected with COVID-19, Hispanic individuals had a higher risk of COVID-19 hospitalization than non-Hispanic White individuals (odds ratio, 2.08, 95% CI, 1.60-2.70) with highly suggestive evidence which remained after sensitivity analyses.

    CONCLUSION: Individuals of Black and Hispanic groups had a higher risk of COVID-19 infection and hospitalization compared to their White counterparts. These associations of race and ethnicity and COVID-19 outcomes existed more obviously in the pre-hospitalization stage. More consideration should be given in this stage for addressing health inequity.

    The objective of the present study was to review published surveys on allelic frequencies S and Z in countries outside Europe to evaluate the validity of the reported data. Studies on the topic, published from 1965 to May 2001, were retrieved using MEDLINE and bibliographic reference consultations. The criteria for the selection of the studies were the following: 1) sample size >or=250 individuals; 2) alpha1-antitrypsin phenotype determination performed by means of crossed antigen-antibody, isoelectric focusing in polyacrylamide gels, or polymerase chain reaction (PCR); 3) PI type determination performed without any previous screening procedure; 4) S and Z 95% CI of the reported outcomes within the limits of a calculated coefficient of variation. Forty-three out of 85 studies comply with the established criteria for being analysed. Worldwide maps of geographical distributions of PI S and PI Z frequencies have been designed by the authors by adding the data provided by these 43 selected studies to the 70 reported in a recent European meta-analysis.

    Over the years, the emphasis on research practices in healthcare has received more recognition than the emphasis on teaching practices. Also, in contrast to the strong focus on aligning care-giving practices with evidence of effectiveness; aligning educational practices with evidences of effectiveness has continued to be neglected. This creates a chasm that hinders the delivery of effective health practices. Many challenges in the current healthcare delivery system warrant a call for a revamp of health professionals' education, and for a greater focus in effective teaching, assessment and supervision. This paper highlights the current challenges in health professional education (as revealed by the Institute of Medicine, IOM, 2003). It focusses on five key issues for promoting teaching excellence, and supports the move for new lecturers to be educationally trained so that 'teaching for learning' becomes current, effective and enjoyable. More importantly, the vision for health professional education that "all health professionals are educated to deliver patient-centred-care as members of an interdisciplinary team, emphasising evidence-based practice, quality improvement approaches, and informatics" can be attained. This vision has important implication for medical lecturers as it means they have to be better educated to teach in order to be prepared to meet the demands of a reformed healthcare system.
