ABSTRACT

Abstract Medicinal plants have long been prescribed in Thailand for centuries. Different constituents of extracts have been used for treating of various infectious diseases. However, there is even less information available regarding the use in fungal skin infection. In order to assess traditional Thai claims about the therapeutic potential, this study is focused on exploring the anti-dermatophyte property of the plants that are currently used as traditional medicines. The potential of four different plant species were selected for investigate in vitro anti-dermatophyte activity. Ethanolic extracts of Chromolaena odorata (L.), Ageratina adenophora (Spreng.), Eclipta prostrate (Linn.), and Acorus calamus (L.). were analysed for their total phenolic content as well as total flavonoid content and were then subjected to test of their anti-dermatophyte properties using agar well diffusion method. Qualitative flavonoids and phenolics analysis of the extracts showed their biologically active constituents. Among the species examined, the result indicated that most of the extracts demonstrated anti-dermatophyte activity. In particular, A. calamus showed the highest efficacy against test organisms. The experiment confirmed the chemical constituents and efficacy of some selected plants and provides a scientific confirmation of the use of Thai plants in traditional medicine for fungal skin infections.

ABSTRACT

OBJECTIVE@#This study explored the rejuvenation mechanisms of Thai polyherbal medicines using different approaches, including in vitro methods, as well as a well-defined nematode model, Caenorhabditis elegans.@*METHODS@#THP-R-SR012 decoction was selected from 23 polyherbal medicines, based on metal-chelating and chain-breaking antioxidant capacities. The influences of this extract on the survival and some stress biomarkers of C. elegans under paraquat-induced oxidative stress were evaluated. Furthermore, lifespan analysis and levels of lipofuscin accumulation were examined in senescent nematodes. The phytochemical profile of THP-R-SR012 was analyzed.@*RESULTS@#Supplementation with THP-R-SR012 decoction significantly increased the mean lifespan and reduced the oxidative damage to C. elegans under oxidative stress conditions. Further, THP-R-SR012 supplementation slightly influenced the lifespan and the level of lipofuscin accumulation during adulthood. Antioxidant-related phytochemical constituents of THP-R-SR012 decoction were rutin, naringenin, 3,4-dihydroxybenzoic acid, gallic acid, glycyrrhizic acid, demethoxycurcumin and 18α-glycyrrhetinic acid.@*CONCLUSION@#The antioxidant potential of THP-R-SR012 was due to its scavenging properties, its enhancement of antioxidant-related enzyme activities, and the presence of the antioxidant-related compound. These results support the traditional use of THP-R-SR012 decoction as a tonic for nourishing and strengthening the whole body.

ABSTRACT

BACKGROUND@#The number of adults aged over 65 years is rapidly increasing in several Southeast Asian countries. Muscle mass decreases with age, leading to sarcopenia. The primary objective of this study was to determine whether differences exist in the body composition and physical strength, according to ethnicity, among community-dwelling Japanese and Thai older adults living in Chiang Mai Province, Thailand.@*METHODS@#A survey was conducted in February and March 2019. Japanese and Thai adults aged ≥ 60 years living in Chiang Mai Province were recruited through community clubs. Participants completed a self-administered questionnaire that enabled collection of data on age, sex, educational background, marital status, annual income, current medical conditions, smoking and alcohol consumption, and exercise habits. Measurements were collected on height, weight, body composition, blood pressure, hand grip, and walking speed for 6 m. Body composition was measured using a standing-posture 8-electrode multifrequency bioimpedance analysis analyzer. Hand grip of each hand was measured with the patient in the standing position using a digital grip dynamometer. Multivariable logistic regression was used to determine factors associated with skeletal muscle mass index (SMI).@*RESULTS@#Of the total 119 participants, 47 were Japanese (26 men, 21 women) and 72 were Thai (16 men, 56 women). The prevalence of a low SMI was 3/26 (12%), 1/21 (5%), 6/16 (38%), and 5/56 (9%) among Japanese men, Japanese women, Thai men, and Thai women, respectively. The prevalence of low muscle strength was 2/26 (8%), 2/21 (10%), 3/16 (19%), and 13/56 (23%) among Japanese men, Japanese women, Thai men, and Thai women, respectively. There were significant differences between ethnic groups in body mass index for both sexes, percentage body fat in women, SMI in men, and average grip strength in men. Ethnic group, sex, age, and body mass index were independent predictors of SMI.@*CONCLUSIONS@#Ethnicity had a clinically important effect on body composition and physical strength among older Japanese and Thai adults living in a similar environment.

ABSTRACT

Kaempferiae Parviflorae Rhizoma is the dried rhizome of Kaempferia parviflora in Zingiberaceae. It is originated and widely distributed in Thailand and other tropical and subtropical regions, where it has been used as food and medicine for thousands of years. K. parviflora is also planted in Yunnan and other places of China, but its traditional Chinese medicine properties are not clear, which greatly limits its compatibility with traditional Chinese medicines. In this article, the English and Chinese literatures of K. parviflora were searched from Web of Science, PubMed, Scopus, CNKI, Wanfang, and VIP databases for research and analysis. The medicinal properties of K. parviflora were preliminarily discussed based on the theory of traditional Chinese medicine under the guidance of clinical application and research literatures. The traditional Chinese medicine properties of K. parviflora were inferred as follows: flat, acrid, sweet. The channel tropisms of K. parviflora included kidney, spleen, stomach, and liver. The function of K. parviflora included tonifying kidney to strengthen essence, tonifying Qi and invigorating spleen, soothing liver and relieving depression. K. parviflora was clinically applied for the diseases such as syndrome of kidney essence deficiency, sex apathy, deficiency of spleen Qi, lassitude and asthenia, a weary spirit, obesity, diabetes, liver Qi stagnation, depression, and restless. The equivalent of dry power is 1.5 g·d~(-1) and the equivalent of decoction is 1.5-6 g·d~(-1). The determination of traditional Chinese medicine properties of K. parviflora has indeed laid a theoretical foundation for its application in the field of traditional Chinese medicine and enriched traditional Chinese medicine resources.

ABSTRACT

Under the background of the Belt and Road Initiative, the exchange of traditional medicine has become inevitable. China and Thailand are amicable neighbors, and the cooperation between the two countries in the field of traditional medicine has become increasingly close in recent years. Nevertheless, on account of the differences in culture, region, politics, economy and so on, the two countries have common features and unique characteristics in the theoretical system of traditional medicine, quality standard control of medicinal materials, research and development and use of medicinal materials. This paper summarizes the similarities and differences as well as the development opportunities of traditional medicine between China and Thailand. The specific content involves the development history, resources, and use of medicinal resources in Thailand, the main achievements and existing problems of modern research of Thai medicine, the spread and development of Chinese medicine in Thailand, and the spread and development of Thai medicine in China. Furthermore, the paper outlines the recent situation of traditional medicine interflow and cooperation between the two countries, and predicts the prospects for cooperation and development of traditional medicine between China and Thailand in the context of the Belt and Road Initiative, especially in the joint research and development and the improvement of quality standards of important medicinal plant varieties commonly used by the two countries and circulated across the border. Through the exchange and mutual learning, we can step up the traditional medicine cooperation between China and Thailand, which will provide advantageous conditions for the safety of medicine use as well as political and social stability between the two countries.

ABSTRACT

Arthropod-borne diseases, such as malaria and dengue fever, have frequently beset five countries(Cambodia, Vietnam, Laos, Myanmar, and Thailand) in the tropical rainy Lancang-Mekong region, which pose a huge threat to social production and daily life. As a resort to such diseases, chemical drugs risk the resistance in plasmodium, non-availability for dengue virus, and pollution to the environment. Traditional medicinal plants have the multi-component, multi-target, and multi-pathway characteristics, which are of great potential in drug development. Exploring potential medicinals for arthropod-borne diseases from traditional medicinal plants has become a hot spot. This study summarized the epidemiological background of arthropod-borne diseases in the Lancang-Mekong region and screened effective herbs from the 350 medicinal plants recorded in CHINA-ASEAN Traditional Medicine. Based on CNKI, VIP, and PubMed, the plants for malaria and dengue fever and those for killing and repelling mosquitoes were respectively sorted out. Their pharmacological effects and mechanisms were reviewed and the material basis was analyzed. The result is expected to serve as a reference for efficient utilization of medicinal resources, development of effective and safe drugs for malaria and dengue fever, and the further cooperation between China and the other five countries in the Lancang-Mekong region.

ABSTRACT

Lancang-Mekong Cooperation is a new type of subregional cooperation mechanism initiated and built by China and other five countries of the Lancang-Mekong subregion, namely Laos, Myanmar, Thailand, Cambodia, and Vietnam. Countries in the Lancang-Mekong subregion are geographically and culturally connected, and they have nurtured their unique traditional medicine. By combing the history of traditional medicine exchanges between China and other Lancang-Mekong countries and their progress of modern research, this paper summarized the challenges and opportunities of traditional medicine cooperation in the Lancang-Mekong subregion. It has been found that many regional cooperation mechanisms coexist for a long time in the Lancang-Mekong subregion and the medicinal resources are abundant. However, the degree of their development and utilization varies, and modern scientific research is insufficient. Lancang-Mekong Cooperation has provided a strong support for integrating the advantageous resources in Lancang-Mekong subregion countries and making progress together. Focusing on the development and protection of medicinal resources, this paper puts forward a new path of cooperation in the intellectual property rights and characteristic seed resource protection, the compilation of universal herbal pharmacopoeia in various countries, the research and development of public health products, and the construction of traditional herbal industry bases, thus enabling the traditional medicine to better protect the public health and building a human health community.

ABSTRACT

SUMMARY: Although molecular techniques evolved considerably in last years, anthropological methods of assessing skeletal remains, continues to be an important tool in the identification process in medico legal investigations. The objective of this study was to develop a discriminant function equation for estimating sex and stature using several measurements of lumbar vertebrae in a Thai population. We studied 150 lumbar columns (75 male and 75 female) age range of 22 to 89 years from the Forensic Osteology Research Center, Chiang Mai University, Thailand. The quantitative variables with sex were analyzed by the discriminant function analysis and that with stature were calculated using linear regression. The pixel density of the major axis of the trabecular surface of superior endplate of the first lumbar vertebra had the most accuracy in sex determination. The regression equation with quantitative variables in stature estimation described 32.3 % of the total variance with standard error of estimate of 7.736 cm. Lumbar vertebrae can be used as part of the stature and sex quantitatively and qualitatively estimating in Thais incomplete skeletal remains.


RESUMEN: Los métodos antropológicos de evaluación del esqueleto siguen siendo una herramienta importante en el proceso de identificación en las investigaciones médico-legales. El objetivo de este estudio fue desarrollar una ecuación de función discriminante para estimar el sexo y la estatura utilizando varias medidas de las vértebras lumbares en una población tailandesa. Se estudiaron 150 columnas lumbares (75 hombres y 75 mujeres) con un rango etario de 22 a 89 años del Centro de Investigación de Osteología Forense, Universidad de Chiang Mai, Tailandia. Las variables cuantitativas de sexo se analizaron mediante el análisis de función discriminante y la estatura fue calculada mediante regresión lineal. En cuanto a la determinación de sexo, la densidad de píxeles del eje mayor de superficie trabecular de la placa terminal superior de la primera vértebra lumbar fue de mayor precisión. La ecuación de regresión con variables cuantitativas en la estimación de la estatura describió el 32,3 % de la varianza total con el error estándar de estimación de 7,736 cm. Las vértebras lumbares se pueden utilizar como parte de la estatura y el sexo, estimando cuantitativa y cualitativamente los restos esqueléticos incompletos en sujetos tailandeses.

ABSTRACT

SUMMARY: The auriculotemporal nerve (ATN) is an important structure lying within a limited area of an infratemporal region (ITR). The ATN is originated from the posterior branch of the mandibular division of the trigeminal nerve (V3). The ATN conveys somatosensory, secretomotor, and parasympathetic fibres of the V3 and gustatory nerve (CN IX). In literature, the most common pattern of the ATN is composed of 2 roots that encloses the middle meningeal artery (MMA). However, in many studies, it has been reported that there are many variations in ATN pattern formation. To study the variation of ATN pattern formation in Thai cadavers, 73 hemifaces from 39 Thai embalmed cadavers were dissected and the relations of the ATN to the MMA were recorded. This study concluded that there were 4 patterns observed in Thai cadavers. The common pattern is 2 roots (67.1 %), 3 roots (15.1 %), 1 root (9.6 %), and 4 roots (8.2 %). Knowledge of this variation in the ATN may be useful in understanding the symptoms of temporo-orofacial pain, paresthesia of temporomandibular joint (TMJ), possible side effects from the TMJ surgery and the efficiency of auriculotemporal nerve block for regional anesthesia of the temporomandibular joint in Thai people.


RESUMEN: El nervio auriculotemporal (NAT) es una estructura importante que se encuentra dentro de la región infratemporal (ITR). El NAT se origina en la rama posterior de la división mandibular del nervio trigémino (V3), y transmite fibras somato sensoriales, secreto motoras y parasimpáticas del V3 y del nervio gustativo (CN IX). En la literatura, se reporta que el patrón más común de NAT está compuesto por 2 raíces que contienen la arteria meníngea media (AMM). Sin embargo, en diversos estudios, se ha informado que existen múltiples variaciones en la for- mación de patrones NAT. Con el objetivo de estudiar la variación de la formación del patrón NAT en cadáveres tailandeses, se disecaron 73 estructuras hemi faciales de 39 cadáveres tailandeses y se registraron las relaciones del NAT con el AMM. En conclusión, se observaron 4 patrones en los cadáveres tailandeses. El patrón común de 2 raíces (67,1 %), 3 raíces (15,1 %), 1 raíz (9,6 %) y 4 raíces (8,2 %). El conocimiento de esta variación en el NAT puede ser útil para comprender los síntomas de dolor temporo-orofacial, parestesia de la articulación temporomandibular (ATM), posibles efectos secundarios de la cirugía de ATM y la eficacia del bloqueo del nervio auriculo-temporal para la anestesia regional de la articulación temporomandibular en Tailandeses.

ABSTRACT

Determination of age represents one of the most important aspects in forensic identification. Through aging, changes can occur in morphological structures of the heart valves. The objective is to examine the relationship between the dimensions of the rigth atrioventricular (tricuspid), pulmonary, left atrioventricular (mitral), and aortic valves and age at death. Sixty fresh human hearts were obtained from Department of Anatomy and Department of Forensic Medicine, Faculty of medicine, Chiang Mai University, Thailand. The age of individuals was between 20-90 years. We investigated the morphometric parameters of the valves were taken including: valve circumference, length, the height and area of each leaflet. All parameters were measured by using specific image analysis software. The correlation test and predictive equation were established. The positive correlation between the circumference, area of posterior leaflet, height of anterior leaflet, and area of anterior leaflet of the rigth atrioventricular valve were found. The left atrioventricular valve showed correlation with age in circumference, length and area of posterior leaflet. For the pulmonary and aortic valves, there were correlated between circumference at sinotubular junction and leaflet sizes in almost leaflets. The circumference at sinotubular junction of the pulmonary valve was highest significantly correlation with age (r=0.693). The predictive equation was age = -3.659+0.652(Circumference at sinotubular junction of the pulmonary valve) with standard error of ± 14.7 years. Additional knowledge of morphometric features in human heart valves and its relationship with age could be used as age indicator in forensic field.


La determinación de la edad representa uno de los aspectos más importantes en la identificación forense. Pueden ocurrir cambios a través del envejecimiento, en las estructuras morfológicas de las válvulas cardíacas. El objetivo de este estudio fue examinar la relación entre las dimensiones de las valvas atrioventricular derecha (tricúspide), pulmonar, atrioventricular izquierda (mitral) y aórtica, y la edad en relación a la muerte. Se obtuvieron sesenta corazones humanos frescos del Departamento de Anatomía y el Departamento de Medicina Forense de la Facultad de Medicina de la Universidad de Chiang Mai, Tailandia. La edad de las personas fluctuaba entre los 20 y 90 años. Investigamos los parámetros morfométricos de las valvas analizadas, incluyendo: circunferencia de la valva, longitud, altura y área de cada valva. Todos los parámetros se midieron utilizando un software de análisis de imagen específico. Se estableció la prueba de correlación y la ecuación predictiva. Se encontró la correlación positiva entre la circunferencia, el área de la valvula posterior, la altura de la valvula anterior y el área de la valvula anterior de la valva atrioventricular derecha. La valva atrioventricular izquierda mostró correlación con la edad en la circunferencia, longitud y área de la valvula posterior. Para las valvas pulmonar y aórtica, se correlacionó entre la circunferencia en la unión sinotubular y el tamaño de las válvulas. La circunferencia en la unión sinotubular de la valva pulmonar fue la mayor correlación significativa con la edad (r = 0,693). La ecuación predictiva fue edad = -3,659 + 0,652 (circunferencia en la unión sinotubular de la valva pulmonar) con error estándar de ± 14,7 años. El conocimiento adicional de las características morfométricas en las valvas cardíacas humanas y su relación con la edad podría usarse como indicador de edad en el campo forense.

ABSTRACT

Abstract The present study was performed to assess the proximate and nutrient content of rainbow trout flesh, cultured in the Doi Inthanon Fisheries Research Unit, Chiang Mai Inland Fisheries Research and Development Center, Thailand. 240 fish were randomly distributed across 12 cages with 20 fish cage-1. Sixteen individual fish from each cage were randomly collected at different ages of 10, 12 and 24 months. Body composition, pH, water-holding capacity, shear force, collagen content analysis, sensory, lipid oxidation, and fatty acids profile were evaluated. The results indicated that body composition and carcass length were significantly higher in fish aged 24 months, except for carcass and viscero-somatic index percentages (P ≤ 0.05). Fish at 24 months showed significantly higher pH, moisture, fat, shear force, thiobarbituric acid reactive substances, and total collagen content values than fish at 10 and 12 months (P ≤ 0.05). However, protein percentage, sensory measurement and water-holding capacity were significantly higher in younger fish at 10 and 12 months. The average lipid content and n-6/n-3 ratios were significantly greater in fish at 12 months and in ventral fillets (P ≤ 0.05). However, polyunsaturated fatty acids: saturated fatty acid ratio was higher in fish at 24 months and in dorsal fillets. In conclusion, rainbow trout cultured in sub-tropical, montane conditions can be valuable sources of protein, unsaturated fatty acids, eicosapentaenoic acids, and docosahexaenoic acids.

The genotyping test was performed by Gap-PCR for three rare deficient thalassemia. The cases with negative detection were further detected by Sanger sequencing method, so as to identify rare α or β thalassemia mutation.@*RESULTS@#1120 specimens were genotyped for thalassemia, out of them 547 thalassemia genes were determined. The detection rate was 48.8% (547/1120). 340 specimens were diagnosed as α thalassemia, and the detection rate was 30.6%, including 266 cases of --/αα, 44 cases of -α/αα, 12 cases of -α/αα, 8 cases of αα/αα,. 3 cases of Hb H disease ( 2 cases of --/-α, 1 case of --/-α), 2 cases of αα/αα, 2 cases of αα/αα, 1 case of -α/-α, and 1 case of -α/αα. Also, they contain 11 cases of rare α thalassemia, 8 kinds of rare types of α thalassemia mutations in combination, such as 4 cases of αα/αα, 1 case of αα/αα, 1 case of αα/αα, 1 case of αα/αα, 1 case of αα/αα, 1 case of αα/αα, 1 case of αα/αα, and 1 case of --/αα. Among them, 5 α mutation sites were first reported, namely αα, αα, αα, αα and αα; 2 α thalassemia mutation sites: αα and -- were detected again in the Chinese population, respectively. 188 specimens were diagnosed as β thalassemia with a detection rate of 16.8%. Among them, 68 cases of β/βN, 47 cases of β/βN, 20 cases of β/βN, 17 cases of β/βN, 7 cases of β/βN, 7 cases of βE/βN, 3 cases of β/βN and 2 cases of β/βN. And 17 cases were diagnosed as rare β thalassemia, 8 kinds of rare types were β thalassemia mutations in combination. There were 4 cases of β/βN, 3 cases of β/βN, 3 cases of β/βN, 2 cases of β/βN, 2 cases of β/βN, 1 case of β/βN, 1 case of β/βN, 1 case of β/βN. Among them, 3 β thalassemia mutation sites were reported for the first time, namely β, β and β; it was found that in the Chinese population as β, β, β, β, and β, respectively. 19 cases were diagnosed as αβ-complex thalassemia, out of which 15 types of thalassemia mutation combinations were detected. They contain 2 cases of rare αβ-complex thalassemia, which are αα/αα complex β/βN, αα in α1/αα complex β/βN.@*CONCLUSION@#The types of thalassemia gene mutations in Nanping area of Fujian province are genetically heterogeneous. The prevention and control strategies of thalassaemia in this area should be based on the prevention and treatment of common α thalassemia and β thalassaemia. And the attention should be paid to the types of rare and unknown gene mutations using screening and testing method.

PCR-flow cytometry fluorescence hybridization assay was used to detect the common thalassemia gene deletions and mutations.@*RESULTS@#8 kinds of abnormal hemoglobinopathy were detected in 200 cases from 34 800 subjects of child-bearing age, the detection rate was 0.57% in couples of child-bearing age in Chongqing: Among 200 cases of abnormal hemoglobin pathy, Hb E was found in 90 cases (accounting for 45.0%), and Hb D in 25 cases (accounting for 12.5%). Hb NewYork was found in 25 cases (accounting for 12.5%). HbJ-bangkok was found in 25 cases (accounting for 12.5%), and Hb Q-Thailand in 16 cases (accounting for 8.0%). Hb Hope was detected in 15 cases (accounting for 7.5%). Hb S was detected in 3 cases (accounting for 1.5%). Hb Hasharon was detected in 1 case (accounting for 0.5%). The mean corpuscular volume (MCV) and mean corpuscular hemoglobin (MCH) of Hb E and Hb Q-Thailand were lower than normal reference intervals.@*CONCLUSION@#The detection rate of abnormal hemoglobinopathy in Chongqing is higher than the average level in China. Capillary electrophoresis can effectively screen abnormal hemoglobinopathy, which is great significant for aristogenesis and improvement of population quality.

ABSTRACT

BACKGROUND: Banana fruit has been recognized as an important food allergen source. Nowadays banana hypersensitivity had been reported more frequently with various presentations from oral allergy syndrome to anaphylaxis.OBJECTIVE: This study aims to describe the pattern of banana hypersensitivity and the sensitivity of diagnostic test.METHODS: Six patients who experienced banana hypersensitivity were recruited from adult allergy clinic, Ramathibodi Hospital, Mahidol University between 2015–2018. Demographic data, pattern of banana allergy consisted of the onset of reaction, symptoms, severity, cross-reactivity to kiwi, avocado, latex including type and amount of banana were collected. Skin test, serum specific IgE to banana and open-label food challenge test had been applied.RESULTS: All patients experienced multiple episodes of banana anaphylaxis. Regarding the diagnostic investigation, prick-to-prick skin test had higher sensitivity (sensitivity, 100%; 95% confidence interval [CI], 54.07%–100%) than the commercial banana extract (sensitivity, 83.33%; 95% CI, 35.88%–99.58%) and serum specific IgE to banana (sensitivity, 50%; 95% CI, 11.81%–88.19%). The discordance between skin prick test using commercial banana extract and skin test was reported. The cross-reactivity between the species of banana, kiwi, the avocado was documented in all patients. Latex skin prick test and application test were applied with negative results. From the oral food challenge test, a case of banana anaphylaxis patient can tolerate heated banana.CONCLUSION: The various phenotypes of banana hypersensitivity were identified. The prick-to-prick test showed the highest sensitivity for diagnosis of banana allergy. However, component resolved diagnostics might be needed for conclusive diagnosis.

ABSTRACT

@#Objectives. To describe the characteristics of long-standing T1DM in Thai patients and assess residual beta-cell function with status of pancreatic autoantibodies. Methodology. This is a cross-sectional study of Thai subjects with T1DM and disease duration ≥ 25 years seen at the Theptarin Hospital. Random plasma C-peptide and pancreatic auto-antibodies (Anti-GAD, Anti-IA2, and Anti-ZnT8) were measured. Patients who developed complications were compared with those who remained free of complications. Results. A total of 20 patients (males 65%, mean age 49.4±12.0 years, BMI 22.5±3.1 kg/m2, A1C 7.9±1.6%) with diabetes duration of 31.9±5.1 years were studied. Half of the participants remained free from any diabetic complications while the proportions reporting retinopathy, nephropathy, and neuropathy were 40%, 30%, and 15%, respectively. HDL cholesterol was significantly higher and triglyceride concentration significantly lower in patients who were free from diabetic nephropathy but not in those who were free from other complications. The prevalence rates of anti-GAD, anti- IA2, and anti-ZnT8 were 65%, 20%, and 10%, respectively. None of the patients who tested negative for both anti-GAD and anti-IA2 was positive for anti-ZnT8. Residual beta-cell function based on detectable random plasma C-peptide (≥ 0.1 ng/mL) and MMTT was found in only 3 patients (15%). There was no relationship between residual beta-cell function and protective effects of diabetic complications. Conclusion. Endogenous insulin secretion persists in some patients with long-standing T1DM and half of longstanding T1DM in Thai patients showed no diabetic complications. HDL cholesterol was significantly higher and triglyceride concentration significantly lower in patients who were free from diabetic nephropathy

ABSTRACT

OBJECTIVES: To estimate the number and risk of imported infections resulting from people visiting Asian and Latin American countries.METHODS: The dataset of visitors to 5 Asian countries with dengue were analyzed for 2016 and 2017, and in the Philippines, Thailand and Vietnam, imported cases of zika virus infection were also reported. For zika virus, a single imported case was reported from Brazil in 2016, and 2 imported cases reported from the Maldives in 2017. To understand the transmissibility in 5 Southeast Asian countries, the estimate of the force of infection, i.e., the hazard of infection per year and the average duration of travel has been extracted. Outbound travel numbers were retrieved from the World Tourism Organization, including business travelers.RESULTS: The incidence of imported dengue in 2016 was estimated at 7.46, 15.00, 2.14, 4.73 and 2.40 per 100,000 travelers visiting Philippines, Indonesia, Thailand, Malaysia and Vietnam, respectively. Similarly, 2.55, 1.65, 1.53, 1.86 and 1.70 per 100,000 travelers in 2017, respectively. It was estimated that there were 60.1 infections (range: from 16.8 to 150.7 infections) with zika virus in Brazil, 2016, and 345.6 infections (range: from 85.4 to 425.5 infections) with zika virus in the Maldives, 2017.CONCLUSION: This study emphasizes that dengue and zika virus infections are mild in their nature, and a substantial number of infections may go undetected. An appropriate risk assessment of zika virus infection must use the estimated total size of infections.
