title: Prevalence, determinants and microvascular complications of type 2 diabetes mellitus among elderly population of Kathmandu, Nepal

description: Background: Diabetes Mellitus (DM) has caused global pandemic which principally involves Type 2 DM. DM can cause several complications including microvascular complications that impose a tremendous burden on the individual and on the health care system. There is little known about prevalence of Type 2 DM and its complications among elderly. The main purpose of this study was- To determine the prevalence of Type 2 DM and its microvascular complications and to identify factors associated with them among elderly population of Kathmandu, Nepal. Methods: Cross sectional study was conducted among 306 participants above age 60 from urban and rural areas of Kathmandu district. Firstly home visits were conducted, where structured questionnaire was used to collect information from the participants. Anthropometric measurements, blood pressure and fasting blood glucose test was done using standard medical tools. Those who were identified as diabetic during home visits were invited to a health camp later, where detailed physical examination, was done for detecting microvascular complications. Data Analysis was done using binary logistic regression with statistical significance of each analysis against the p value of 0.05. Results: Prevalence of Type 2 DM in this study was 23.5% which is similar to the findings of previous studies in Kathmandu. Among all cases of Type 2 DM 26.3% were the new cases diagnosed during survey and 43.1% have one or more of the microvascular complications. Inadequate Physical activity, Unhealthy Diet, Frequent visit to Fast food centers, Family history of Type 2 DM, Presence of Hypertension and History of Gestational Diabetes Mellitus were significantly positively associated with presence of Type 2 DM. Likewise, Above Normal waist circumference and DM Duration were significantly positively associated with microvascular complications of Type 2 DM. Whereas, Healthy Diet was negatively associated with microvascular complications. Conclusions: Prevalence of Type 2 DM and its microvascular complication is high in Kathmandu, along with undetected cases of Type 2 DM. The burden of DM and its microvascular complications calls the attention of the policy makers to devise some strategy to increase access to health care facilities. Health education and cost effective preventive interventions must be promoted to prevent the rising trend of Type 2 DM.

title: Foreign direct investment : implication for economic development in Lao PDR

description: Most developing countries rely on some form of trade and foreign investment for Foreign Direct Investment (FDI) has considerable significance for transitional economy countries like Lao PDR as well their economic development. This study is aimed at understanding of role of FDI in economic development in Lao PDR through focusing on resource sector and also this study examined the FDI situation in Lao PDR since 1988. The study found that, since 1988, Lao PDR offers investment opportunities for foreign companies and has adopted a number of policies to attract foreign direct investment into the country. Law on foreign investment was revised three times. FDI in the Lao People’s Democratic Republic has improved clearly since around mid-2000. Mining and electricity generation sectors account for much of FDI, and are likely to remain the most active sector for foreign investment. FDI are expected to bring benefit to host country. The study also found that FDI has positive impact on economy in the form of higher economic growth, an increase in revenues, and export performance. From 2006 to 2010, average GDP growth rate in Lao PDR was 7.9% and in 2011, it was 8.4%. Export increased significantly over the decade due to the increase of export in mining and electricity. However, aside from benefit, resource sectors have a negative impact in term of environmental problem.

description: Childhood overweight and obesity has become an important public health problem in Thailand. A study was carried to assess the situation of obesity and overweight of Thai children attending grade levels 5-9 in BMA bilingual schools in Bangkok, Thailand. The research was a cross-sectional, analytical study. The study used purposive sampling and stratified random sampling. Two hundred and fifty students were selected as subjects for the study from six different BMA bilingual schools. Data were collected by self-administered questionnaire and analyzed by applying descriptive statistics (percentage, mean, standard deviation) to describe the data, and logistic regression to examine the relationship between independent and dependent variables. The results revealed that the prevalence of overweight was 10.4% and obesity was 8.4% in Thai children attending grade levels 5-9 in BMA bilingual. The study also showed that there were statistically significant associations between children’s diet practice (adjusted OR 2.4, 95% CI 0.946-6.103) and body image (adjusted OR 0.09, 95% CI 0.012-0.650) with childhood overweight and obesity. The findings indicated that childhood obesity is prevalent in BMA bilingual schools in Bangkok, Thailand. Childhood overweight and obesity is a serious public health problem based on its increasing rates and the associated health risks. Obesity is a multifactorial chronic diseases stemming from complex interactions between genes and environment. Future studies should consider other lifestyle and psychological factors in a larger age group. Finally, policies should improve the health-education program to signify the importance of dietary habits and physical activity. A much directive approach on the food-environment on the school’s compound and intervention should be directed not only on school children, but include the whole family are recommended.

title: Health risk Reduction Behaviors Model (HRRBM) of scavenger labors exposed to solid waste at local waste disposal site in Nakhon Ratchasima province, Thailand

description: Objective 1) To investigate the general characteristics and self-protection behaviors of scavengers at local waste disposal sites, Nakhon Ratchasima Province 2) To explore the association between knowledge, attitudes and practices among scavengers exposed to solid waste at local waste disposal sites 3) To develop and evaluate the effectiveness of the Health Risk Reduction Behaviors Model (HRRBM) in regards to solid waste exposure among scavengers at local waste disposal sites at Nakhon Ratchasima Province, Thailand Methods: Phase 1 Cross-sectional study; Questionnaire was conducted by face to face interviewed with 88 scavengers working in local waste disposal site and observed with observation form. Phase 2 Quasi-experimental study was conducted of scavenger subjects divided into two groups. An intervention group of 44 subjects was randomly selected from 63 scavengers at a municipal waste dump site and a control group of 44 subjects was randomly selected from 58 scavengers at 8 additional dump sites. The Health Risk Reduction Behaviors Model (HRRBM) was developed and implemented with the intervention group. Results: Phase 1: The majority of scavengers were female. An average age was 38 years old. They were married and had worked as a scavenger for more than 10 years. The average income was 5,800 baht/month. Most of them graduated in primary school. More than half of the participants in both groups rarely used Personal Protective Equipments (PPEs) during their work time and were careless regarding annual medical checkups. Reinforcing health risk behaviors were smoking, drinking alcohol finding and eating unclean food at the dump sites during their work. Phase 2: the knowledge, attitudes and practices between groups after the HRRBM intervention showed significant difference (p&lt;0.05). The mean difference of knowledge, attitudes, and practices increased significantly in the invention group (p&lt;0.05), but in the control group, there was no difference in knowledge. Physical symptoms slightly decreased in the intervention group, whereas in control group was no difference. There was a significant increase in the proportion of PPEs used in the intervention group (p&lt;0.05) but, this remained the same in the control group. Conclusion and Discussion: The HRRBM significantly reduced self-health care cost, significantly increased knowledge, attitudes and practices regarding working with solid waste, reduced percentage of uncomfortable condition and physical symptoms, and increased proportion of PPEs used the intervention was implemented in the intervention group compared with the control group. In conclusion, scavengers exposed to solid waste at waste disposal sites can reduce health risk exposure if they strictly follow the safety recommendation regarding routine work. The health care coordinator should distribute the HRRBM, media and routine monitor for safety work practices.

title: Synthesis of 1,4-dihydropyridine derivatives as novel fluorescent sensors

description: This research involves the synthetic preparation of a series of 1,4-dihydropyridine (DHP) by varying substituent of nitrogen atom. The DHP triester (1) can be easily prepared from the cyclotrimerization of β-amino acrylate by treatment of TiCl4 at room temperature. Hydrolysis of 1 was carried out using KOH to convert triester to tricarboxylic acid (2), which readily soluble in aqueous media. The photophysical properties of these DHP derivatives were studied in pH 8.0 phosphate buffer solution. The absorption spectra displayed absorption maximum in the range of 280 to 300 and 347 to 358 nm. All of these compounds exhibited an emission peak in a range of 432-445 nm with fluorescence quantum efficiencies (f) of 0.07-0.23. Since methoxyphenyl N-substituted DHP showed the highest blue emission appearance also observable by naked-eye, it was therefore selected for further investigation in fluorescence sensing applications. This derivative was found to selectively interact with Hg2+ and the fluorescent signal decrease was assumed to be the result of an oxidation of the DHP into a pyridinium ring specifically induced by Hg2+ that brought about its remarkable selectivity over other metal ions. The decrease of fluorescence signal was proportional to Hg2+ concentration with high quenching efficiency (Ksv = 78,300 M-1) providing a detection limit of 0.2 µM. According to the results, of the use of tricarboxylic acid 2 Fe2+ and Fe3+ detection with protein BSA, as the sensitivity of BSA to Fe2+ and Fe3+ was increased two-fold-higher in the presence of 2. This tricarboxylic acid 2 was also tested with various types of surfactant. Its fluorescent signal was enhanced selectively by SDBS, and the CMC of SDBS could be determined by this method as 1.4 mM (literature CMC values is 1.2 mM). Additionally, the different fluorescence behavior of compound 2 in THF by nitroaromatic explosive compounds, such as trinitrotoluene, 4-nitrotoluene and 2,4-nitrotoluene might be useful for the explosive detection.

title: Factors influencing concentration-to-dose ratio of lamotrigine in Thai patients

description: Background Genetic variation is one of factors that contribute to the interindividual variability of pharmacokinetic. UGT1A4 is the major enzyme responsible for lamotrigine metabolism. Therefore, UGT1A4 polymorphisms could lead to the variability of glucuronidation enzyme activity and may contribute to the difference of lamotrigine pharmacokinetics among ethnicities. Objectives To investigate the effect of genetic (UGT1A4 polymorphisms) and non-genetic factors (age, gender, body weight, and co-medications) on lamotrigine concentration-to-dose ratio (LTG-CDR) in Thai patients. Methods A prospective analysis study in 73 patients from Prasat Neurological Institute, who had stable lamotrigine dose for at least 2 weeks. Lamotrigine plasma concentration was determined using HPLC method. Genotyping of UGT1A4 was carried out by Taqman allelic discrimination assays. ANOVA was used to compare LTG-CDR among groups of different polymorphism. Multiple regression analysis was performed to investigate an association of all factors and LTG-CDR. Results The allele frequency of UGT1A4 142 T&gt;G in Thai patients was 27%. However, the variant of UGT1A4 70 C&gt;T was not found. The LTG-CDR of patients having at least 1 variant allele (T/G or G/G) was significantly lower than patients having wild type allele (T/T) for patients using lamotrigine monotherapy or lamotrigine + enzyme inhibitor + enzyme inducers (p=0.019). The stepwise regression model showed that age, the use of enzyme inducers, and enzyme inhibitor influence LTG-CDR. This model could explain 20.40% of the variance of LTG-CDR.Conclusion UGT1A4 polymorphism may contribute to the variability of LTG-CDR in Thai population. However, after accounting for age and co-medications, the influence of UGT1A4 polymorphism was not found.

title: Cyanide fluorescent sensors from diphenylacetylene derivatives

description: A novel series cyanide fluorescence sensors (F1-F4) containing phenylene-ethynylene as fluorogenic center and salicylaldehyde as CN- receptor were successfully synthesized by using Sonogashira coupling reaction as a key synthetic step. The sensors exhibited selective fluorescence turn-on responses in contact with cyanide anion in aqueous DMSO or aqueous media containing Triton X-100 non ionic surfactant. The fluorescence turn-on signal is associated with the reduction of the quenching effect by internal charge transfer (ICT) process within the sensing molecules. Upon the addition of cyanide anion, the resonance electron withdrawing aldehyde group is converted into the corresponding cyanohydrin which is no longer capable of withdrawing the electrons by the resonance effect. F3, which contain one salisadehyde group and two phenylene-ethynylenes, gives the highest cyanide sensitivity among four compounds synthesized. The fluorescence quantum yields determined before and after the cyanide addition confirm that the fluorescence quenching by the ICT process in F3 is reduced the most. The detection limit of this cyanide sensor is 1.6 μM (42 ppb) in the aqueous media which is below the concentration limited by WHO in drinking water of 2.7 μM. The paper-based solid state sensors fabricated from F3 allow naked eye detection of cyanide anion down to 5 nanomole.

title: The analysis of unit cost in-patient services at the urology department in Thai Nguyen General Hospital in Vietnam

description: This research is a descriptive study aimed at analyzing the cost structure and unit cost of in-inpatient services at urology department of Thai Nguyen General Hospital in 2011. This study was carried out from 21/03/2012 to 2/4/2012. This study is based on the provider perspective. All departments at Thai Nguyen general hospital were classified into three groups which include non–revenue producing cost centers, revenue producing cost centers and patient service centers. The total direct cost of Thai Nguyen general hospital is estimated by considering labor cost, material cost and capital cost, where capital cost includes the cost of building and the cost of equipment. The step-down method is used to allocate cost among cost centers. The allocation is based on allocation criteria which were created specifically for each cost centers. The full cost of the urology department was US$ 20,455 in 2011 the number of in-patients in this department was 503 and the number of inpatient days was 6,016. The unit cost of inpatient services at urology department was US$ 3.4. This unit cost was 7.23 times higher than partial user-fee for one inpatient service. To reduce the gap between unit cost of inpatient services at urology department and the partial user-fee for one inpatient service, the hospital should focus on using the high quality, high technology and long useful life equipment to reduce capital cost. Government should allocate resources to hospital based on quality of hospital instead using number of hospital beds.

title: Mineral chemistry of inclusions in basaltic sapphires from Southeast Asia

description: Mineral inclusions in sapphires from Bo Phloi, Kanchanaburi, in particular, and some from Chanthaburi and Phrae in Thailand; Huai Sai in Laos; Pailin in Cambodia and Gia Nghia in Vietnam were selected for this study. Mineral inclusions discovered in Bo Phloi sapphires include alkali feldspar, nepheline, hercynitic spinel, zircon, manganiferous-ilmenite, silica-rich enstatite, pyrope-almandine garnet richer towards pyrope component, monazite, calcite, sapphirine, biotite-phlogopite and staurolite. These mineral inclusions can be categorized into two groups namely felsic alkaline suite and contact metamorphic suite, which appear to have originated from different environments. These inclusion suits has provided new evidences to propose a bimodal genetic model of Bo Phloi sapphire. Firstly, the felsic alkaline-related origin is based on the occurrence of felsic alkaline inclusion suite together with trace elements and REE’s geochemistry of sapphire-associated zircons indicating that majority of the sapphires appear to have crystallized in an environment related to high alkali felsic melt at lower crust. Secondly, the contact metamorphic-related origin is based on the finding of contact metamorphic inclusion suite, suggesting that some of these sapphires could also originate from the metasomatised crustal rocks and contaminated melt at contact zone of basaltic intrusion at upper mantle or lower crust. Furthermore, most mineral inclusions found in Southeast Asia sapphires also are similar to those inclusions observed in Bo Phloi sapphires, except ilmenite, monazite, calcite and biotite-phlogopite have not so far been found in Southeast Asia sapphires, while ferrocolumbite, pyrochlore and apatite inclusions appear in these sapphires. Therefore, the mineral inclusions found in Southeast Asia sapphires are also divided into two groups namely ‘syenitic melt-related’ and ‘contact metamorphic-related’ suites. It can be proposed that sapphires in Southeast Asia region also originated from the bimodal genetic model similar to those occur in Bo Phloi sapphires. U-Pb dating data of Bo Phloi zircon inclusion yield an age of 24±0.9 Ma including Th-U-Pb age of monazite inclusions at 25-30 and 42-45 Ma that are very close to the volcanism of Cenozoic basalts in Thailand. Therefore, the sapphire formation may have the same thermal history as partial melting in the upper mantle leading to early state of Cenozoic basaltic eruption of Thailand as well as Southeast Asia region
