    "The commitment to population programs is now widespread," says Rafael Salas, Executive Director of the UNFPA, in its report "State of World Population." About 80% of the total population of the developing world live in countries which consider their fertility levels too high and would like them reduced. An important impetus came from the World Conference of 1974. The Plan of Action from the conference projected population growth rates in developing countries of 2.0% by 1985. Today it looks as though this projection will be realized. While in 1969, for example, only 26 developing countries had programs aimed at lowering or maintaining fertility levels, by 1980 there were 59. The International Population Conference, recently announced by the UN for 1984, will, it is hoped, help sustain that momentum. Cuba is the country which has shown the greatest decline in birth rate so far. The birth rate fell 47% between 1965-1970 and 1975-1980. Next came China with a 34% decline in the same period. After these came a group of countries--each with populations of over 10 million--with declines of between 15 and 25%: Chile, Colombia, India, Indonesia, the Republic of Korea, Malaysia and Thailand. Though birth rates have been dropping significantly the decline in mortality rates over recent years has been less than was hoped for. The 1974 conference set 74 years as the target for the world's average expectation of life, to be reached by the year 2000. But the UN now predicts that the developing countries will have only reached 63 or 64 years by then. High infant and child mortality rates, particularly in Africa, are among the major causes. The report identifies the status of women as an important determinant of family size. Evidence from the UNFPA-sponsored World Fertility Survey shows that in general the fertility of women decreases as their income increases. It also indicates that women who have been educated and who work outside the home are likely to have smaller families. Access to contraceptives is, of course, a major influence on fertility decline. According to UNFPA some of the Latin American countries have the highest contraceptive use among developing countries. The countries of Asia come next and contraceptives are least used in sub-Saharan Africa where birth rates of 45/1000 are still common. The money for population programs, says the report, has come largely from developing countries themselves. A survey of 15 countries showed them to have contributed 67% out of their own budgets--the rest having come from external aid. And in programs aided by UNFPA the local input has been even higher. During 1979-1981 the developing countries themselves budgeted $4.6 for each dollar budgeted by UNFPA. The report also highlights some of the emerging problems for the next 2 decades--and which will be high on the agenda of the 1984 conference. These include "uncontrolled urban growth" in developing countries as well as an important change in overall population age structure as more and more old people survive. Aging populations are of particular concern to the developed countries but, as the report points out, even countries like China--which has achieved a steep drop in fertility and mortality--will face the problems of an aging population by the year 2000.

    Child mortality may affect spacing through biological and behavioral channels. The death of a child may elicit a desire to have another one soon; further, it may interrupt breastfeeding and shorten the sterile period following childbirth. The hypothesis that the child mortality-spacing linkage varies across parities, being strongest in the middle parities, is examined using microdata from Malaysia and the Cox-regression technique. The empirical results lend support to the hypothesis.

    Currently, the effects of chronic, continuous low dose environmental irradiation on the mitochondrial genome of resident small mammals are unknown. Using the bank vole (Myodes glareolus) as a model system, we tested the hypothesis that approximately 50 generations of exposure to the Chernobyl environment has significantly altered genetic diversity of the mitochondrial genome. Using deep sequencing, we compared mitochondrial genomes from 131 individuals from reference sites with radioactive contamination comparable to that present in northern Ukraine before the 26 April 1986 meltdown, to populations where substantial fallout was deposited following the nuclear accident. Population genetic variables revealed significant differences among populations from contaminated and uncontaminated localities. Therefore, we rejected the null hypothesis of no significant genetic effect from 50 generations of exposure to the environment created by the Chernobyl meltdown. Samples from contaminated localities exhibited significantly higher numbers of haplotypes and polymorphic loci, elevated genetic diversity, and a significantly higher average number of substitutions per site across mitochondrial gene regions. Observed genetic variation was dominated by synonymous mutations, which may indicate a history of purify selection against nonsynonymous or insertion/deletion mutations. These significant differences were not attributable to sample size artifacts. The observed increase in mitochondrial genomic diversity in voles from radioactive sites is consistent with the possibility that chronic, continuous irradiation resulting from the Chernobyl disaster has produced an accelerated mutation rate in this species over the last 25 years. Our results, being the first to demonstrate this phenomenon in a wild mammalian species, are important for understanding genetic consequences of exposure to low-dose radiation sources.

    Introduction: Undernutrition among under-five children is a very common issue in Malaysia, especially among the Orang Asli population. Therefore, identifying the prevalence and factors associated with undernutrition will assist in tackling the issue of undernutrition and reducing the morbidity and mortality rate associated with it. Methods: A total of 47 conveniently selected Orang Asli children aged 6 to 59 months from Kampung Paya Bungor, Gambang, Kuantan, Pahang participated in this cross-sectional study. A face-to-face interview was carried out by using the validated Questionnaire for the Study of Malnutrition in Rural Malaysia 2009. The weight and height of the children were measured and plotted on the growth chart. All the data were analyzed using IBM SPSS Statistics Version 24.0. Descriptive statistics was used to describe the background characteristics of the respondents and univariate analyses were used to identify suitable factors to be included in multivariate analysis. Binary logistic regression was done to determine independent factors associated with undernutrition. Results: The overall prevalence of undernutrition was 55.3%. The prevalence of underweight, stunting and wasting was 34.0%, 34.0% and 14.9% respectively. This research also revealed that gender (p=0.042) and family size (p=0.024) was shown to have a statistically significant association with undernutrition. However, there were no significant associations between undernutrition with other factors. Conclusion: The prevalence of undernutrition among under-five Orang Asli children was a concern. It was found that the factors associated with undernutrition were female children and children from small families. Prompt interventions aimed at the Orang Asli community should be done to overcome these problems.

    Humans express a wide array of ideal mate preferences. Around the world, people desire romantic partners who are intelligent, healthy, kind, physically attractive, wealthy, and more. In order for these ideal preferences to guide the choice of actual romantic partners, human mating psychology must possess a means to integrate information across these many preference dimensions into summaries of the overall mate value of their potential mates. Here we explore the computational design of this mate preference integration process using a large sample of n = 14,487 people from 45 countries around the world. We combine this large cross-cultural sample with agent-based models to compare eight hypothesized models of human mating markets. Across cultures, people higher in mate value appear to experience greater power of choice on the mating market in that they set higher ideal standards, better fulfill their preferences in choice, and pair with higher mate value partners. Furthermore, we find that this cross-culturally universal pattern of mate choice is most consistent with a Euclidean model of mate preference integration.

    An analysis of population coverage of hypertension treatment services can be used to make inferences about the performance of primary care services within health systems. Malaysia, an upper middle-income country, has a well-established primary care system but one that favors rural populations and provision of services for maternal and child health and infectious diseases. Demographic factors including rapid aging, urbanization, as well as lifestyle changes characteristic of a modernizing society have led to an increase in noncommunicable diseases, including hypertension. In this article, we used data from a nationally representative household health survey to develop service coverage indicators for hypertension screening and treatment services. The age-standardized prevalence of hypertension was estimated to be 33.9% (95% confidence interval [CI], 33.9, 33.9). Only 39.0% (95% CI, 37.5, 40.6) of adults with hypertension had been diagnosed by a medical practitioner, 35.7% had been on treatment, and 9.6% had blood pressure controlled under treatment. The diagnosis, treatment, and controlled treatment coverage were higher for older persons compared to younger persons. There were no differences in the diagnosis and treatment coverage between urban and rural areas and between ethnic groups. However, controlled treatment coverage was higher among Chinese and those living in urban areas. Our findings suggest that primary care services in Malaysia may need to intensify health education activities to promote screening services. There is also a need to reprioritize activities to provide regular community health screening of adults and increase access to affordable primary care services, especially in the urban areas.

    OBJECTIVES: Currently, Malaysia faces great challenges in allocating adequate resources for healthcare services using a tax-based system. Therefore, Malaysia has no choice but to reform its healthcare financing system. The objective of this study is to assess Malaysian household willingness to pay and acceptance levels to the proposed National Health Financing Scheme.

    STUDY DESIGN: This is a cross-sectional study.

    METHODS: In total, 774 households from four states in Malaysia completed face-to-face interviews. A validated structured questionnaire was used, which was composed of a combination of open-ended questions, bidding games and contingent valuation methods regarding the participants' willingness to pay.

    RESULTS: The study found that the majority of households supported the establishment of the National Health Financing Scheme, and half proposed that a government body should manage the scheme. Most (87.5%) of the households were willing to contribute 0.5-1% of their salaries to the scheme through monthly deductions. Over three-quarters (76.6%) were willing to contribute to a higher level scheme (1-2%) to gain access to both public and private healthcare basic services. Willingness to pay for the National Health Financing Scheme was significantly higher among younger persons, females, those located in rural areas, those with a higher income and those with an illness.

    CONCLUSION: There is a high level of acceptance for the National Health Financing Scheme in the Malaysian community, and they are willing to pay for a scheme organised by a government body. However, acceptance and willingness to pay are strongly linked to household socio-economic status. Policymakers should initiate plans to establish the National Health Financing Scheme to provide the necessary financing for a sustainable health system.

    OBJECTIVES: A long-term civil conflict has been occurring in the southernmost provinces of Thailand, and migration to Malaysia has been accelerated by this conflict. The objective of this work was to examine the influence of perceived effects of the unrest, migration of a household member, and children left behind on the reporting of psychiatric symptoms of working age adults.

    METHODS: A first round of data collection was conducted in 2014 including interviews with a probability sample of 1102 households and individual interviews with 2058 males and females aged 18-59. In 2016, a second round of data collection was conducted. A fixed effects model was used in the analysis.

    RESULTS: The perceived effect of the unrest on the household was associated with an increased reporting of psychiatric symptoms. Furthermore, the migration of a household member for work and the presence of children left behind were related to an increased reporting of psychiatric symptoms among adults, especially among females.

    CONCLUSIONS: The unrest and its associated migration was related to an increased reporting of psychiatric symptoms among working age adults in the study population.

    There is an interest in the sustainable utilization of waste cotton cloths because of their enormous volume of generation and high cellulose content. Waste cotton cloths generated are disposed of in a landfill, which causes environmental pollution and leads to the waste of useful resources. In the present study, cellulose nanocrystals (CNCs) were isolated from waste cotton cloths collected from a landfill. The waste cotton cloths collected from the landfill were sterilized and cleaned using supercritical CO2 (scCO2) technology. The cellulose was extracted from scCO2-treated waste cotton cloths using alkaline pulping and bleaching processes. Subsequently, the CNCs were isolated using the H2SO4 hydrolysis of cellulose. The isolated CNCs were analyzed to determine the morphological, chemical, thermal, and physical properties with various analytical methods, including attenuated total reflection-Fourier transform-infrared spectroscopy (ATR-FTIR), field-emission scanning electron microscopy (FE-SEM), energy-filtered transmission electron microscopy (EF-TEM), X-ray diffraction (XRD), thermogravimetric analysis (TGA), and differential scanning calorimetry (DSC). The results showed that the isolated CNCs had a needle-like structure with a length and diameter of 10-30 and 2-6 nm, respectively, and an aspect ratio of 5-15, respectively. Additionally, the isolated CNCs had a high crystallinity index with a good thermal stability. The findings of the present study revealed the potential of recycling waste cotton cloths to produce a value-added product.

    Cigarette smoke produces more than 4,000 toxic chemicals and 53 of these chemicals can cause cancer. Smoking increases your health risks such as lung cancer, heart attack and stroke. In Malaysia, between 10% and 12% of causes of death are caused by smoking and this results in over 10,000 deaths a year. According to the National Health Morbidity Survey (NHMS) in 2015, the number of smokers aged 15 and above in Malaysia is estimated to be more than 5 million (22.8%). This alarming amount will lead to increased health costs. Smoking can also lead to a reduction in worker productivity and air pollution and the pollution due to cigarette smoke. Therefore, smokers need to be aware of the effects of smoking habits and the importance of maintaining a tobacco-free environment for the health and well-being of their families, friends and the community around them. To address this, Smoke Busters have created an innovation called Blue Ribbon Star Certification with an additional component of humanization into the TFI Buddies existing Blue Ribbon Certification. The main goal of this innovation is to make University of Technology MARA (UiTM) campuses 100% tobacco free. The first project at the Sungai Buloh Campus resulted in a decrease in the percentage of ‘hotspots’, whereby the number of cigarette butts was found to be greatly reduced. In addition, the percentage of staff with good knowledge and attitude on the effects of cigarettes increased. Feedback from users comprising staff and students also showed a very positive response. The direct impact on faculty and campuses include cost savings in terms of medical expenses and increase in staff productivity. The long-term effects include enhancing UiTM’s image nationally and internationally. From a social point of view, this in addition creates a more caring and responsible generation of colleagues and the environment.

    Nigeria is naturally blessed with wide diversity of native animal genetic resources. Indigenous ruminant livestock such as cattle, camel, donkey, sheep and goat contributes largely in both protein supply, revenue generation and national economy. In Nigeria, these animal resources are mismanaged and undermined through the indiscriminate slaughter of pregnant animals and foetal losses in abattoirs. This unethical practice resulted in the loss of genetic diversity, preferred traits and superior females ruminant animals. The current research focus on reported incidences across abattoirs, which is a centre where such practice is highly occurs within the country. Lack of modern facilities, law enforcement, poor management and animal welfare in abattoirs to protect pregnant animals are among few factors responsible for an increase in incidences. It is unprofitable to continue the tradition of pregnant animal slaughter that causes foetal losses. This is a condition that significantly threatens the animal genetic resources and general livestock industry in Nigeria. This practice must be discard with a proper conservation and documentation of these valuable animal genetic resources. Both long and short terms conservation programs must aim for substantial benefits of these resources. Laws must be enforced with strict penalties to those involved in pregnant animal slaughter. Genetic resources of these species and meat industry future could be safe with proper implementation of these laws and conservation measures.

    Hereditary or developmental neurological disorders (HNDs or DNDs) affect the quality of life and contribute to the high mortality rates among neonates. Most HNDs are incurable, and the search for new and effective treatments is hampered by challenges peculiar to the human brain, which is guarded by the near-impervious blood-brain barrier. Clustered Regularly Interspaced Short Palindromic Repeat (CRISPR), a gene-editing tool repurposed from bacterial defense systems against viruses, has been touted by some as a panacea for genetic diseases. CRISPR has expedited the research into HNDs, enabling the generation of in vitro and in vivo models to simulate the changes in human physiology caused by genetic variation. In this review, we describe the basic principles and workings of CRISPR and the modifications that have been made to broaden its applications. Then, we review important CRISPR-based studies that have opened new doors to the treatment of HNDs such as fragile X syndrome and Down syndrome. We also discuss how CRISPR can be used to generate research models to examine the effects of genetic variation and caffeine therapy on the developing brain. Several drawbacks of CRISPR may preclude its use at the clinics, particularly the vulnerability of neuronal cells to the adverse effect of gene editing, and the inefficiency of CRISPR delivery into the brain. In concluding the review, we offer some suggestions for enhancing the gene-editing efficacy of CRISPR and how it may be morphed into safe and effective therapy for HNDs and other brain disorders.

    Background: In primary care, general practitioners (GPs) and pharmacists are tasked with the frontline responsibility of identifying and managing allergic rhinitis (AR) patients. There are currently no consolidated data on current treatment practices, patient compliance, and usage of guidelines within Southeast Asian Nations (ASEAN). Objective: To assess the attitudes and practices on AR of GPs and pharmacists in 4 ASEAN countries (Philippines, Indonesia, Thailand, and Malaysia).

    Methods: A cross-sectional survey of 329 GPs and 548 pharmacists was conducted from May to November 2019. Participants answered a questionnaire focused on their i) current practice in the management of AR, ii) views on patient compliance, iii) understanding and usage of guidelines.

    Results: Clinical history was the most preferred method to diagnose AR by 95.4% of GPs and 58.8% of pharmacists. Second-generation antihistamines were the most widely available treatment option in GP clinics and pharmacies (94.8% and 97.2%) and correspondingly the most preferred treatment for both mild (90.3%, 76.8%) to moderatesevere rhinitis (90.3%, 78.6%) by GPs and pharmacists, respectively. Loratadine was ranked as the most preferred 2nd generation antihistamines (GP vs pharmacists: 55.3% vs 58.9%). More than 90% of GPs and pharmacists ranked length and efficacy of treatment as important factors that increase patient compliance. Awareness of the ARIA guidelines was high among GPs (80%) and lower among pharmacists (48.4%). However, only 63.3% of GPs and 48.2% of pharmacists knew how to identify AR patients.

    Conclusions: The survey in the 4 ASEAN countries has identified a need to strengthen the awareness and use of ARIA guidelines among the primary care practitioners. Adherence to ARIA guidelines, choosing the appropriate treatment option and prioritizing factors that increases patient compliance may contribute to better management outcomes of AR at the primary care practice.

    Although handwashing is an effective way to prevent infections, there is scarce evidence on predictors of handwashing during a pandemic. This paper aims to identify behavioural and demographic predictors of handwashing. The study surveyed 674 adults in Malaysia in May 2020 regarding whether the time spent on social media predicted handwashing contingent on gender and number of children. More time spent on social media was positively associated with handwashing for males with three or more children. However, for males without children, social media use was negatively associated with handwashing. The association was not significant for males with one or two children. For females, more time spent on social media was significantly linked to more handwashing only for females with one child. Gender, a traditional predictor of handwashing, was a useful predictor only for those who spent more than three hours per day on social media and had at most one child. Number of children was a novel negative predictor for males who did not use social media and who averaged one hour per day on social media, a positive predictor for males who spent lots of time on social media, but not a predictor for females. In sum, social media use predicts handwashing, and is thus a helpful variable for use in targeted health communication during a pandemic - particularly through social media. Further, more conventional predictors like gender and number of children exhibit contingency effects with social media use.

    Microglial cells are the primary immune cell resident in the brain. Growing evidence indicates that microglial cells play a prominent role in alcohol-induced brain pathologies. However, alcohol-induced effects on microglial cells and the underlying mechanisms are not fully understood, and evidence exists to support generation of oxidative stress due to NADPH oxidases (NOX_-mediated production of reactive oxygen species (ROS). Here, we investigated the role of the oxidative stress-sensitive Ca2+-permeable transient receptor potential melastatin-related 2 (TRPM2) channel in ethanol (EtOH)-induced microglial cell death using BV2 microglial cells. Like H2O2, exposure to EtOH induced concentration-dependent cell death, assessed using a propidium iodide assay. H2O2/EtOH-induced cell death was inhibited by treatment with TRPM2 channel inhibitors and also treatment with poly(ADP-ribose) polymerase (PARP) inhibitors, demonstrating the critical role of PARP and the TRPM2 channel in EtOH-induced cell death. Exposure to EtOH, as expected, led to an increase in ROS production, shown using imaging of 2',7'-dichlorofluorescein fluorescence. Consistently, EtOH-induced microglial cell death was suppressed by inhibition of NADPH oxidase (NOX) as well as inhibition of protein kinase C. Taken together, our results suggest that exposure to high doses of ethanol can induce microglial cell death via the NOX/ROS/PARP/TRPM2 signaling pathway, providing novel and potentially important insights into alcohol-induced brain pathologies.

    Introduction: Peripheral nerve injuries (PNI) are a disabling injury as it often results in motor and sensory deficit with cognitive impairment. Flaxseed oil provides a good source of omega-3 fatty acid and it is believed to be able to protect the damaged nerve cell for successful nerve recovery. This study aimed to investigate a potential neuro-re- generation properties of flaxseed oil in treating the PNI. Methods: A total of 65 rats were separated into 4 groups: Group 1: Normal group (n=5), Group 2: Negative group (n=20), Group 3: Experimental group (n=20) and Group 4: Positive control (n=20), all the group were further divided into 4 groups (post-operative 7, 14, 21, 28 days, n=5 for each days). The functional restoration was assessed by walking track analysis (Sciatic Functional Index analysis-SFI) and toe spreading reflex (grading score). Electron microscope studies were performed on sciatic nerve to evaluate the regenerative process through morphologic and morphometric changes. Results: Oral administration of flaxseed oil (experimental group) at 1000 mg/kg body weight/day showed better recovery compared to negative control value. However, there was no significant difference in SFI and toe spreading reflex between positive (mecobalamin) and experimental group (flaxseed oil). Morphological and morphometrical findings indicated increases in the myelin thickness and myelin sheath layer after administration of flaxseed oil. Conclusion: The flaxseed oil supplementation could enhance the neurorestorative capacities of injured sciatic nerve.

    Neuraminidase (NA) is an integral membrane protein of influenza A virus (IAV) and primarily aids in the release of progeny virions, following the intracellular viral replication cycle. In an attempt to discover new functions of NA, we conducted a classical yeast two-hybrid screen and found acute myeloid leukaemia marker 1 (AML1) as a novel interacting partner of IAV-NA. The interaction was further validated by co-immunoprecipitation in IAV-infected cells and in an in vitro coupled transcription/translation system. Interestingly, we found an increase in the expression of AML1 upon IAV infection in a dose-dependent manner. As expected, we also observed an increase in the IFN-β levels, the first line of defence against viral infections. Subsequently, when AML1 was downregulated using siRNA, the IFN-β levels were found to be remarkably reduced. Our study also shows that AML1 is induced upon IAV infection and results in the induction of IFN-β. Thus, AML1 is proposed to be an important player in IFN induction and has a role in an antiviral response against IAV infection. SIGNIFICANCE AND IMPACT OF THE STUDY: Influenza epidemics and pandemics are constant threats to human health. Development of antiviral therapeutics has focused on important and major IAV proteins as targets. However, the rate at which this virus mutates makes the task challenging. Thus, next-generation approaches aim at host cellular proteins that aid the virus in its replication. This study reports a new host-virus interaction, of acute myeloid leukaemia marker 1 (AML1) with influenza A neuraminidase (IAV-NA). We have found that this interaction has a direct effect on the upregulation of host IFN-β response. Further studies may lead to a greater understanding of this new innate defence pathway in infected cells.

    In the state effort reduce the number of maternal death, a free child and maternal healthcare programme were introduced called Successful delivery. This main aim of this research is to evaluate if women registered with the programme had a better chance of accessing the services in the state. A crosssectional quantitative study involving household interviews of all women of the reproductive age group (15–49 years) residing in Jigawa state from February to April 2019. Logistic regression analysis at 95% confidence interval was used to determine the independent associations between the scheme and use of antenatal care, hospital delivery and postnatal care services. Successful delivery program influenced the antenatal care visit as women registered with the schemes are more likely to have maximum of six visit 39.5 times than those who did not and also more likely to have four visit 2.6 times than those without scheme. Hospital delivery is also attached to the scheme as women registered with the scheme is 5.3 times likely to deliver at hospital when compared to those with not. Successful delivery program influence antenatal care visit and hospital base delivery. Nevertheless many of the pregnant women after delivery did not attend postnatal care.

    This work introduces a new additive named 4,4'-trimethylenedipiperidine for the practical and ecofriendly preparation of ethyl 5-amino-7-(4-phenyl)-4,7-dihydro-[1,2,4]triazolo[1,5-a]pyrimidine-6-carboxylate derivatives. This chemical is commercially available and easy to handle. It also possesses a low melting point and a broad liquid range temperature, high thermal stability, and good solubility in water. Based on green chemistry principles, the reaction was performed in a) a mixture of green solvents i.e. water and ethanol (1:1 v/v) at reflux temperature, and b) the additive was liquefied at 65 °C and the reaction was conducted in the liquid state of the additive. High yields of the desired triazolo-pyrimidines were obtained under both aforementioned conditions. Our results demonstrated that this additive, containing 2 Lewis base sites and able to act as an acceptor-donor hydrogen bonding group, is a novel and efficient alternative to piperidine, owing to its unique properties such as its reduced toxicity, nonflammable nature, nonvolatile state, broad liquid range temperature, high thermal stability, and ability to be safely handled. Furthermore, this additive could be completely recovered and exhibited high recyclability without any change in its chemical structure and no significant reduction in its activity. The current methodology has several advantages: (a) it avoids the use of hazardous materials, as well as toxic, volatile, and flammable solvents, (b) it does not entail tedious processes, harsh conditions, and the multistep preparation of catalysts, (c) it uses a metal-free and noncorrosive catalyst, and (d) reduces the generation of hazardous waste and simple work-up processes. The most important result of this study is that 4,4'-trimethylenedipiperidine can be a promising alternative for toxic, volatile, and flammable base reagents in organic synthesis owing to its unique properties.
