RESUMO

Hemoglobin (Hb) F has a modulatory effect on the clinical phenotype of ß-thalassemia disease. High expression of Hb F in Hb E-related disorders has been noted, but the mechanism is not well understood. We have examined the association of a novel SNP rs11759328 on ARHGAP 18 gene and other known modulators with a variability of Hb F in Hb E-related disorders. Genotyping of SNP rs11759328 (G/A) was performed based on high-resolution melting analysis. The rs11759328 (A allele) was shown to be significantly associated with Hb F levels (p < 0.05) in heterozygous and homozygous Hb E. High levels of Hb F in both heterozygous and homozygous Hb E were also found to be associated with SNPs in the study of other modifying genes including KLF 1 mutation, rs7482144 (Gγ-XmnI), rs4895441, rs9399137 of (HBS1L-MYB), and rs4671393 (BCL11A). Multivariate analysis showed that KLF1 mutation and SNP rs11759328 (GA) (ARHGAP18) modulated Hb F expression in heterozygous Hb E. For homozygous Hb E, this was found to be related to five modifying factors, i.e., KLF1 mutation, rs4895441 (GG), rs9399137 (CC), rs4671393 (AA), and rs4671393 (GA). These results indicate that a novel SNP rs11759328 is a genetically modifying factor associated with increased Hb F in Hb E disorder.

RESUMO

OBJECTIVE: To determine whether restrictive or routine episiotomy in term pregnant Southeast Asian women results in fewer complications. DESIGN: A multicentre randomised controlled trial. SETTING: Two tertiary and two general hospitals in Thailand. POPULATION: 3006 singleton pregnant women 18 years or older, ≥37 weeks of gestation, cephalic presentation and planned vaginal delivery. METHODS: This randomised controlled trial compared routine versus restrictive episiotomies in Thai women giving birth vaginally. Participants were singleton, term pregnant women with cephalic presentation. Block randomisation was stratified by study site and parity. Risk ratios (RR) and 95% confidence intervals (CI) were calculated to indicate between-group differences. MAIN OUTCOME MEASURES: Primary outcome was severe perineal laceration. Secondary outcomes included vaginal laceration, cervical laceration, and pregnancy outcomes. RESULTS: 3006 women were randomly assigned to restrictive (1502) and routine (1504) episiotomy. There was no difference in severe perineal laceration between the groups (RR 0.72, 95% CI 0.46-1.12). Restrictive episiotomy resulted in more intact perineums in multiparous women (RR 3.09, 95% CI 2.10-4.56). Restrictive episiotomy increased the risk of vaginal laceration in primiparous (RR 1.96, 95% CI 1.62-2.37) and multiparous women (RR 2.21, 95% CI 1.77-2.75) but did not lead to more suturing. There were comparable risks of cervical laceration, postpartum haemorrhage, wound complication, birth asphyxia, and admission to neonatal intensive care unit. CONCLUSIONS: Restrictive episiotomy results in more intact perineum in multiparous women. Risks of maternal and neonatal outcomes were comparable between the two practices. These results strengthen the certainty of the existing Cochrane review findings in supporting restrictive episiotomy. TWEETABLE ABSTRACT: Restrictive episiotomy results in more intact perineums after vaginal birth in multiparous Southeast Asian women.

RESUMO

OBJECTIVES: This study investigated the perception of dental students on becoming innovative healthcare professionals. The specific objective was to identify aspects of innovative healthcare development that could spur their interest in becoming more involved in healthcare research and new product development. METHODS: Survey research was conducted via questionnaires using a five-point Likert scale response. Based on the innovation science literature, each questionnaire comprised three sets of questions that might foster dental students' interest in healthcare innovation development. Data were obtained from 265 students from years 2, 4 and 6. RESULTS: Three critical dimensions of dental student's preferences were revealed. First, socially related goals were identified as important for developing healthcare innovation. Second, non-traditional learning activities, especially lectures from experienced innovators or an industrial trip were suggested to foster interest in healthcare innovation. Third, the students thought it was important to learn about the research process that translates scientific findings into healthcare innovation. CONCLUSIONS: This study identifies potential ways to develop dental clinicians' interest in becoming innovative professionals who are involved in healthcare product development. This is especially true for Thailand where commercially based innovation has not yet flourished.

RESUMO

A novel actinomycete, strain PA1-10T, isolated from the leaf of Phyllanthus amarus collected from Bangkok, Thailand, was characterized taxonomically using a polyphasic approach. This strain contained the characteristics consistent with those of members of the genus Nonomuraea. It formed short rugose spore chain on aerial mycelium. The diamino acid in cell wall peptidoglycan was meso-diaminopimelic acid. Galactose, glucose, madurose, mannose, and ribose were found in whole-cell hydrolysates. Predominant menaquinones were MK-9 (H2), MK-9 (H4), and MK-9 (H6). Major cellular fatty acids were iso-C16:0 and C17:0 10-methyl. Phospholipid profiles were composed of phosphatidylinositol mannoside (PIM), lyso-phosphatidylethanolamine (lyso-PE), phosphatidylethanolamine (PE), methylphosphatidylethanolamine (PME), diphosphatidylglycerol (DPG), and phosphatidylglycerol (PG). The G + C content of DNA was 71.2 mol%. Strain PA1-10T showed the highest 16S rRNA gene sequence similarity with Nonomuraea candida JCM 15928T (98.35%) and shared the same node with Nonomuraea maritima JCM 18321T in the phylogenetic tree analysis. Based on the phenotypic characteristics, DNA-DNA relatedness, and average nucleotide identity (ANI), the strain is considered to represent a novel species of the genus Nonomuraea, for which the name Nonomuraea phyllanthi is proposed. The type strain is PA1-10T (= JCM 33073T = NBRC 112774T = TISTR 2497T).

RESUMO

Opisthorchiasis-associated cholangiocarcinoma (OV-CCA) is a major public health problem in Greater Mekong Subregion (GMS) Countries, the poorest region in Asia. People in this region have similar traditions or respect the same religion. There is no difference in lifestyle and food culture. Excluding Thailand, publications on risk factors for OV-CCA from the GMS Countries are few, especially data on behavioral risk factors for OV-CCA. Therefore, this study aimed to assess the behavior-related risk factors and to compare the risk of OV-CCA among rural people living along the Mekong River in five GMS countries. It was a cross-sectional analytic study during June and October 2017. All participants with informed consent completed the questionnaires. Descriptive statistics were used to describe the prevalence of risk factors. Odds ratio with 95% confidence intervals were used to compare the risk of OV-CCA. It was found that there were more drinkers than non-drinkers in all areas, except in Vietnam. The highest history of liver fluke infection was found in Cambodia. Praziquantel use and consumption of raw freshwater fish dishes were mostly found in Lao PDR. The highest consumption of nitrosamine-contaminated foodstuffs was found in Ubon Ratchathani, Thailand. The spatial comparison of OV-CCA risk showed that Lao PDR and Ubon Ratchathani were two risk areas when compared to Tachileik, Myanmar (a reference area). This study provided the behavior-related risk factors for OV-CCA among people in five GMS Countries which would be a major jigsaw puzzle leading to proactive surveillance for OV-CCA prevention in the future.

RESUMO

PURPOSE: To compare students' knowledge, attitudes towards oral health, and plaque scores after oral health education sessions delivered by trained schoolteachers vs the control group. MATERIALS AND METHODS: The participants, comprising third-grade students in Amphoe Meuang, Nakhonphanom province (N = 435), were randomly divided into an experimental group (n = 216) and a control group (n = 219). Baseline data of the students' oral health knowledge, attitudes, and plaque scores were collected at the beginning of the study. The experimental group was given oral health education sessions by trained schoolteachers using a specifically designed student handbook, while the control group did not receive extra oral health education other than the national curriculum. The immediate post-test knowledge was evaluated after each session, and plaque scores were determined after the brushing session. After the oral health education programme ended, the experimental and control groups performed a monthly toothbrushing activity for 2 months. Final assessment of the students' knowledge, attitudes, and plaque score was done at the 3-month follow-up. RESULTS: The experimental group's oral health knowledge statistically significantly improved immediately after each session and was still statistically significant during the following three months. This improvement was also statistically significantly higher compared with the control group. The attitudes towards oral health care, foods related to caries, and dental visit improved. The plaque score of the experimental group was statistically significantly lower immediately post-brushing, but was not statistically significantly different at the 3-month follow-up compared with baseline. CONCLUSION: The children receiving oral health education provided by trained schoolteachers had statistically significantly greater oral health knowledge and more positive attitudes towards oral health than the children who had not received the programme. No statistically significant differences in plaque scores were found after 3 months.

RESUMO

BACKGROUND: Cholera is a major public health concern in displaced-person camps, which often contend with overcrowding and scarcity of resources. Maela, the largest and longest-standing refugee camp in Thailand, located along the Thai-Burmese border, experienced four cholera outbreaks between 2005 and 2010. In 2013, a cholera vaccine campaign was implemented in the camp. To assist in the evaluation of the campaign and planning for subsequent campaigns, we developed a mathematical model of cholera in Maela. METHODS: We formulated a Susceptible-Infectious-Water-Recovered-based transmission model and estimated parameters using incidence data from 2010. We next evaluated the reduction in cases conferred by several immunization strategies, varying timing, effectiveness, and resources (i.e., vaccine availability). After the vaccine campaign, we generated case forecasts for the next year, to inform on-the-ground decision-making regarding whether a booster campaign was needed. RESULTS: We found that preexposure vaccination can substantially reduce the risk of cholera even when <50% of the population is given the full two-dose series. Additionally, the preferred number of doses per person should be considered in the context of one vs. two dose effectiveness and vaccine availability. For reactive vaccination, a trade-off between timing and effectiveness was revealed, indicating that it may be beneficial to give one dose to more people rather than two doses to fewer people, given that a two-dose schedule would incur a delay in administration of the second dose. Forecasting using realistic coverage levels predicted that there was no need for a booster campaign in 2014 (consistent with our predictions, there was not a cholera epidemic in 2014). CONCLUSIONS: Our analyses suggest that vaccination in conjunction with ongoing water sanitation and hygiene efforts provides an effective strategy for controlling cholera outbreaks in refugee camps. Effective preexposure vaccination depends on timing and effectiveness. If a camp is facing an outbreak, delayed distribution of vaccines can substantially alter the effectiveness of reactive vaccination, suggesting that quick distribution of vaccines may be more important than ensuring every individual receives both vaccine doses. Overall, this analysis illustrates how mathematical models can be applied in public health practice, to assist in evaluating alternative intervention strategies and inform decision-making.

RESUMO

Peri-urban aquacultures produce nutritious food in proximity to markets, but poor surface water quality in rapidly expanding megacities threatens their success in emerging economies. Our study compared, for a wide range of parameters, water quality downstream of Bangkok with aquaculture regulations and standards. For parameters not meeting those requirements, we sought to establish whether aquaculture practice or external factors were responsible. We applied conventional and advanced methods, including micropollutant analysis, genetic markers, and 16S rRNA amplicon sequencing, to investigate three family-owned aquacultures spanning extensive, semi-intensive and intensive practices. Canals draining the city of Bangkok did not meet quality standards for water to be used in aquaculture, and were sources for faecal coliforms, Bacteriodes, Prevotella, Human E. coli, tetracycline resistance genes, and nitrogen into the aquaculture ponds. Because of these inputs, aquacultures suffered algae blooms, with and without fertilizer and feed addition to the ponds. The aquacultures were sources of salinity and the herbicide diuron into the canals. Diuron was detectable in shrimp, but not at a level of concern to human health. Given the extent and nature of pollution, peri-urban water policy should prioritize charging for urban wastewater treatment over water fees for small-scale agricultural users. The extensive aquaculture attenuated per year an estimated twenty population equivalents of nitrogen pollution and trillions of faecal coliform bacteria inputs from the canal. Extensive aquacultures could thus contribute to peri-urban blue-green infrastructures providing ecosystem services to the urban population such as flood risk management, food production and water pollution attenuation.

RESUMO

One of the advantages for initial survival of inhaled fungal spores in the respiratory tract is the ability for iron acquisition via hemolytic factor-production. To examine the ability of indoor Aspergillus and Penicillium affecting hemolysis, the secreted factors during the growth of thirteen strains from eight species were characterized in vitro for their hemolytic activity (HA) and CAMP-like reaction. The hemolytic index of HA on human blood agar of Aspergillus micronesiensis, Aspergillus wentii, Aspergillus westerdijkiae, Penicillium citrinum, Penicillium copticola, Penicillium paxilli, Penicillium steckii, and Penicillium sumatrense were 1.72 ± 0.34, 1.61 ± 0.41, 1.69 ± 0.16, 1.58 ± 0.46, 3.10 ± 0.51, 1.22 ± 0.19, 2.55 ± 0.22, and 1.90 ± 0.14, respectively. The secreted factors of an Aspergillus wentii showed high HA when grown in undernourished broth at 25°C at an exponential phase and were heat sensitive. Its secreted proteins have an estimated relative molecular weight over 50 kDa. Whereas, the factors of Penicillium steckii were secreted in a similar condition at a late exponential phase but showed low HA and heat tolerance. In a CAMP-like test with sheep blood, the synergistic hemolytic reactions between most tested mold strains and Staphylococcus aureus were identified. Moreover, the enhancement of α-hemolysis of Staphylococcus aureus could occur through the interaction of Staphylococcus aureus-sphingomyelinase and CAMP-like factors secreted from Aspergillus micronesiensis. Further studies on the characterization of purified hemolytic- and CAMP-like-factors secreted from Aspergillus wentii and Aspergillus micronesiensis may lead to more understanding of their involvement of hemolysis and cytolysis for fungal survival prior to pathogenesis.

RESUMO

BACKGROUND: Road traffic injuries (RTIs) have been one of the most critical public health problems in Thailand for decades. The objective of this study was to examine to what extent provincial economy was associated with RTIs, road traffic deaths and case fatality rate in Thailand. METHODS: A secondary data analysis on time-series data was applied. The unit of analysis was a panel of 77 provinces during 2012-2016. Data were obtained from relevant public authorities, including the Ministry of Public Health. Descriptive statistics and econometric models, using negative binomial (NB) regression, negative binomial regression with random-effects (RE) model, and spatial Durbin model (SDM) were employed. The main predictor variable was gross domestic product (GDP) per capita and the outcome variables were incidence proportion of RTIs, traffic deaths and case fatality rate. The analysis was adjusted for key covariates. RESULTS: The incidence proportion of RTIs rose from 449.0 to 524.9 cases per 100,000 population from 2012 till 2016, whereas the incidence of traffic fatalities fluctuated between 29.7 and 33.2 deaths per 100,000 population. Case fatality rate steadily stood at 0.06-0.07 deaths per victim. RTIs and traffic deaths appeared to be positively correlated with provincial economy in the NB regression and the RE model. In the SDM, a log-Baht increase in GDP per capita (equivalent to a growth of GDP per capita by about 2.7 times) enlarged the incidence proportion of injuries and deaths by about a quarter (23.8-30.7%) with statistical significance. No statistical significance was found in case fatality rate by the SDM. The SDM also presented the best model fitness relative to other models. CONCLUSION: The incidence proportion of traffic injuries and deaths appeared to rise alongside provincial prosperity. This means that RTIs-preventive measures should be more intensified in economically well-off areas. Furthermore, entrepreneurs and business sectors that gain economic benefit in a particular province should share responsibility in RTIs prevention in the area where their businesses are running. Further studies that explore others determinants of road safety, such as patterns of vehicles used, attitudes and knowledge of motorists, investment in safety measures, and compliance with traffic laws, are recommended.

RESUMO

Event free survival at 24 months (EFS24) has been described as a powerful predictor for outcome in several subtypes of B cell lymphoma. However, it was limitedly described in T cell lymphoma. We explored the implication of EFS24 as a predictor marker for peripheral T cell lymphoma (PTCL). We reviewed 293 systemic PTCL patients at 13 nationwide major university hospitals in Thailand from 2007 to 2014. The median event free survival (EFS) and overall survival (OS) of PTCL patients in our cohort was 16.3 and 27.7 months with corresponding 2-year EFS and 2-year OS of 45.8% and 51.9%, respectively. A total of 118 patients achieved EFS24 (no events during the first 24 mo). Patients who achieved EFS24 had better OS than patients who did not (2-y OS 92% vs 18.8%; HR, 0.1; P < .001). The standardized mortality ratio of patients achieving EFS24 was 18.7 (95% CI, 14.6-22.8). Multivariable analysis demonstrated performance status, histologic subtype, remission status, and EFS24 achievement as independent predictors for OS. Our study affirmed the value of EFS24 as a powerful prognostic factor for PTCL. Further validation in prospective study setting is warranted.

RESUMO

The Kokarit Frog, recently referred to as Hylarana lateralis (Boulenger), is widely distributed throughout Indochina (Cambodia, Laos, Vietnam), Thailand, Myanmar and southern China. The position of this species in ranid systematics remains unclear; accordingly to the latest revision by Oliver et al. (2015), it was formally withdrawn from the genus Hylarana, but not assigned to any other hylaranine genus and currently is referred to as "Hylarana" lateralis (Frost 2019).

RESUMO

An integrative taxonomic analysis of Subdoluseps herberti from southern Thailand and Peninsular Malaysia and S. samajaya from Sarawak, East Malaysia (Borneo) recovers the former as paraphyletic with respect to the latter. The analyses recover the three southernmost populations of S. herberti in Peninsular Malaysia as conspecific and the sister lineage of S. samajaya, whereas S. herberti from Thailand and northern Peninsular Malaysia constitute the sister species to S. samajaya plus the southern three Peninsular Malaysian populations. As such, the southern populations are described herein as S. malayana sp. nov. and all three species are referred to as the S. herberti group. Clade boundaries and breaks within this group on the Thai-Malay Peninsula occurring at the Isthmus of Kra, across the Kangar-Pattani line, and between the Thai-Malay Peninsula and Borneo are consistent with phylogeographic patterns of other Sundaic taxa. The discovery of S. malayana sp. nov. continues to underscore the fact that, despite the well-studied nature of the lizard fauna of Peninsular Malaysia, much of it still remains unrealized and for conservation efforts to move forward, field research followed by expeditiously revised taxonomies must continue.

RESUMO

A review of female mutillids in southern Thailand is presented, based on literature, loaned material, and two field expeditions. Thirty-three species in 23 genera have been previously recorded from Thailand (Lelej 2005; Lelej et al. 2016, 2017; Okayasu et al. 2018). In March and April 2017, 337 female specimens were collected in the provinces of Krabi, Nakhon Si Thammarat, Phatthalung, Songkhla, and Trang. In May 2018, 255 female specimens were collected in the provinces of Kanchanaburi, Phetchaburi, and Surat Thani. These collected specimens were sorted into 38 morphospecies: 13 already known from Thailand, nine previously described species newly recorded from Thailand, and 16 new to science and described here. Based on loaned material, three more described species were newly recorded from southern Thailand and one more undescribed species was found. Keys to females of the 31 mutillid genera found in southeast Asia and 42 mutillid species studied from southern Thailand are provided. Illustrations and diagnoses are provided for each species studied in southern Thailand, including the following 17 new species: Bischoffitilla tokay Williams, Bischoffitilla cambrai Williams, Mickelomyrme puttasoki Williams, Mickelomyrme kinguri Williams, Nordeniella maleeae Williams, Smicromyrme helarctos Williams, Smicromyrme borkenti Williams, Smicromyrme thaochani Williams, Krombeinidia agricola Williams, Krombeinidia chang Williams, Krombeinidia baanmaka Williams, Orientidia manleyi Williams, Orientidia thoawanae Williams, Petersenidia modkhong Williams, Petersenidia leleji Williams, Trogaspidia pittsi Williams, and Trogaspidia wilsoni Williams. Three new synonyms and one new combination are recognized: Bischoffitilla lamellata (Mickel, 1933) = Squamulotilla arundinacea Pagden, 1934, syn. nov., Mickelomyrme pusillaeformis (Hammer, 1962), comb. nov. = Mickelomyrme yunnanensis Lelej, 1996, syn. nov., Trogaspidia pagdeni (Mickel, 1933) = Timulla (Trogaspidia) pagdeni nodoa Mickel, 1933, syn. nov. Finally, two other taxa are raised to full species from subspecies status, Eotrogaspidia oryzae (Pagden, 1934), status resurr., and Trogaspidia lingnani (Mickel, 1933), status nov. New combination is also proposed for Krombeinidia meeungensis (Cockerell, 1928), comb. nov. Twenty-three new country records are presented: 12 from Thailand, four from Vietnam, four from Laos, two from Cambodia, and one from Indonesia.

RESUMO

Sparsorythus is a genus of Tricorythidae from the Oriental Region. Sparsorythus multilabeculatus Sroka Soldán, 2008 was described based on a male imago from Vietnam. Unknown nymphs and female subimagines of Sparsorythus and male imagines of S. multilabeculatus were collected from Thap Lan National Park, Khon Buri District, Nakhon Ratchasima Province, Thailand. Nymphs and female subimagines of Sparsorythus were associated with male imagines of S. multilabeculatus by analyzing sequences from the DNA barcoding region of the mitochrondrial gene cytochrome oxidase I. Phylogenetic analysis based on Maximum Likelihood indicated that all unknown specimens are conspecific with male imagines of S. multilabeculatus (bootstrap 100% and genetic distance 0-0.004). Male and female nymphs, female subimago and egg are described for the first time. Nymphs each bear a medial emargination on the hypopharynx, one bristle-like process at the base of the left prostheca, and a bifurcate rudimentary gill on abdominal segment VII. The male usually has smudges and light blotches on its forewings; the penis extends to the basal segment of the forceps and reaches to approximately 1/3 of the second segment of the forceps. Forewings of the female subimago have dark colour over more than half of the basal area, and the distal portion of each wing is translucent. The egg has a rounded pole; the polar cap covers approximately 1/4 of the surface; and the surface is covered with hexagonal structures.
