Density Relationship of the Assassin Bugs Sycanus falleni Stål and Sycanus croceovittatus Dohrn (Hemiptera: Reduviidae) and Principal Corn Pests (Noctuidae: Lepidoptera) in Hoa Binh Province, Vietnam

The group of assassin bugs including the Sycanus falleni and Sycanus croceovittatus species were such potential candidates for biocontrol of key pests (fall armyworm Spodoptera frugiperda, black cutworm Agrotis ypsilon, cotton bollworm Heliothis armigera Hübner, maize caterpillar Mythimna loreyi (Lepidoptera: Noctuidae)) on Corn biomass in Hoa Binh Province. Seven species of assassin bugs belonging to the family Reduviidae as S. falleni Stål, S. croceovittatus Dohrn, Coranus spiniscutis Reuter, Coranus fuscipennis Reuter, Polytoxus fuscovittatus (Stål), Endochus nigricornis Stål, Sphedanoletes pubinotum Reuter were recorded on the Corn biomass, of which S. falleni and S. croceovittatus were common. The relationship between the density of the group of assassin bugs and the density species S. falleni, S. croceovittatus had a close relationship with each other (R=0.81, R=0.72 respectively). The relationship between the density of the group of assassin bugs and the density of their prey (4 key pests) on the Corn biomass in the Winter crops and Summer-fall crops were a close relationship with each other (R2= 0.5166, R2= 0.7274 respectively). The relationship between the density of the species S. falleni, S. croceovittatus and the density of their prey (4 key pests) in the Winter crops, and the Summer fall crops were a close relationship with each other (R2 =0.7815, R2 =0.5396 respectively). However, these relationships were not closely related in the Spring-Summer crops and Winter-Spring crops

Sibling bullying among Vietnamese children: the relation with peer bullying and subjective well-being

Background:Siblings play an important role in a child’s life. However, many children often experience sibling bullying. This study investigates differences in sibling victimization by sex, age, a parent’s absence from the home due to employment, or a child’s privacy and the relationship between sibling victimization, peer victimization, and the child’s well-being.Participants and procedure:Participants were Vietnamese children participating in the third wave of the International Survey of Children’s Well-Being. The study included 1537 children (811 boys and 726 girls) attending public schools, age 10-14 years (M = 11.29, SD = 1.15).Results:The results show that over half of children with siblings in this study reported being victimized by a sibling. Younger children were bullied more often than older children. Children whose father worked away from home reported an increase in bullying behavior from their siblings. Children sharing a room with siblings reported being bullied more by siblings.Conclusions:The results indicated a positive correlation between sibling victimization and peer victimization and a negative rela-tionship between being bullied and a child’s subjective well-being.Background:Siblings play an important role in a child’s life.

Maturity and Well-Being: Consistent Associations Across Samples and Measures

Introduction: Researchers have noted an association between maturity and well-being. However, this body of research uses different measures and conceptualizations of maturity (e.g., ego development, psychosocial maturity) and often only a few indicators of well-being. In the present research, we examined associations between a single self-rated measure of maturity and a variety of different indicators of well-being. Furthermore, we examined this association across a variety of samples. We hypothesized that maturity will show a positive relationship with measures related to well-being. Methods: Samples of college students (Studies 1, 3, 4), Star Wars fans (Study 2), and individuals in the U.S., Canada, Brazil, Vietnam, and India (Study 5) completed a short measure of maturity and measures related to well-being. Results: Across the studies, self-rated maturity was consistently positively correlated with various indicators of well-being (e.g., psychological, physical) and related constructs (e.g., self-compassion, empathy). Conclusion: The results highlight the association between maturity and well-being. Furthermore, the results address the fragmented nature of this association in the literature by showing consistent relationships with a variety of well-being indicators with a single measure of maturity. Assessments of maturity may be beneficial in hiring decisions and student evaluation in the healthcare profession

Genome Sequence of a Virulent African Swine Fever Virus Isolated in 2020 from a Domestic Pig in Northern Vietnam

This study reports the genome sequence of an isolated African swine fever (ASF) virus (VNUA-ASFV-05L1/HaNam) obtained at the fourth passage on pulmonary alveolar macrophages. The virus was isolated during a typical acute ASF outbreak in pigs in a northern province of Vietnam in 2020

Effects of medicinal plants mixture on growth performance, nutrient digestibility, blood profiles, and fecal microbiota in growing pigs.

peer reviewed[en] BACKGROUND AND AIM: Alternative natural materials to antibiotics for improving digestive health and growth performance are needed due to strengthening regulations related to the use of antibiotic growth promoters. The study aimed to evaluate the effects of medicinal plants mixture (60% Bidens pilosa L., 15% Urena lobata L., 15% Pseuderanthemum palatiferum, 5% Ramulus cinnamomi, and 5% Star anise) as alternative growth promotors on animal health, nutrient digestibility, blood parameters, and growth performance of growing pigs. MATERIALS AND METHODS: The study was conducted, from April 2020 to June 2020, at a private pig production farm located in Cam Giang district Hai Duong Province, Vietnam. Forty-eight 10-week-old crossbred (♂Duroc×♀ [Landrace×Yorkshire]) pigs, average initial body weight 30.3±1.42 kg, were randomly allocated to four dietary groups, three replicate pens per experimental group, with 4 pigs/pen. For 7 weeks, the pigs were fed a basal diet supplemented with the mixture at levels of 0, 20, 40, and 60 g/kg of feed. RESULTS: Final body weight, average daily gain, average daily feed intake, and feed conversion ratio, as well as apparent total tract digestibility of dry matter, organic matter, crude protein, ether extract, and gross energy were not significantly influenced by the diets (p>0.05). Inclusion of the plant mixture decreased significantly red blood cell count, blood cholesterol, urea nitrogen, and low-density lipoprotein (LDL) concentrations (p<0.05) compared with the control diet. No diet effect was observed on fecal Escherichia coli, Salmonella spp., Clostridium spp., and total bacteria counts. CONCLUSION: The incorporation of the plant mixture into the diet of growing pigs reduced serum cholesterol, LDL, and urea concentrations with no adverse effect on performance and nutrient digestibility.2.

Live Poultry Exposures, Hong Kong and Hanoi, 2006

Since 1997, the largest epidemic of highly pathogenic avian influenza (H5N1) ever recorded has caused 172 human and several billion bird deaths. Recently administered questionnaires determined that live poultry exposures have declined by ≈63% in Hong Kong since 2004 and that, in Vietnam, domestic backyard exposures to poultry are likely more important than retail exposures

Blood pressure percentiles and systemic hypertension-associated factors among children aged between 6 and 15 years in Southern Vietnam

Background: The present study determined blood pressure percentiles in children aged between 6 and 15 years in Southern Vietnam. Material and methods: Blood pressure was measured in a random sample of 1080 students aged 6–15 years who was studying at primary and secondary high schools in My Tho city, Vietnam. A descriptive cross-sectional study was conducted from November 2019 to June 2020. To diagnose children systemic hypertension, the blood pressure must be above the 95th percentile. Data were analyzed by IBM SPSS statistics software version 20.0. The Chi-squared test was employed to evaluate the relationship between systemic hypertension and child demographic characteristics including gender and obesity. Results: The results showed that the 95th percentiles of systolic and diastolic blood pressure of the children was 110/70 mm Hg in the 6-year-old group, 120/75 mm Hg in the 7 to12-year-old group and 125/80 mm Hg in the 13 to 15-year-old group, respectively. The rate of systemic hypertension in the children was 10% whereas boys had a 1.2 time higher risk of systemic hypertension than girls (p &gt; 0.05). Obese children had an 8.6 time higher risk of systemic hypertension than non-obese ones (p &lt; 0.001). Conclusion: The blood pressure percentile chart of school children aged 6–15 years were reported here for the first time in Vietnam. The results provided useful information in early diagnosis and timely treatment of systemic hypertension in children

Acute Kidney Injury After Percutaneous Coronary Intervention Guided by Intravascular Ultrasound

Purpose We investigated the impact of intravascular ultrasound guidance on reducing the incidence of contrast-induced acute kidney injury (CI-AKI) in patients undergoing percutaneous coronary intervention (PCI). Methods Ninety-nine patients were enrolled in this prospective cohort who were not randomly assigned to angiography-guided percutaneous coronary intervention or intravascular ultrasound-guided percutaneous coronary intervention. The patients were hospitalized at the Vietnam National Heart Institute - Bach Mai Hospital between 2019 and 2020. Acute kidney injury incidence during hospitalization was the primary endpoint. Results A total of 99 patients were divided into two groups: the intravascular ultrasound-guided group (33 participants) and the angiography-guided group (66 participants). The mean ± SD contrast volume of each group was 95.2 ± 37.1 mL and 133.0 ± 36.0 mL for the ultrasound-guided and angiography-guided groups, with P \u3c 0.0001. Intravascular imaging-guided percutaneous coronary intervention (IVUS-guided PCI) was associated with reduced acute kidney injury incidence during hospitalization: 0.0% vs. 12.12% and P = 0.049. Conclusions Intravascular ultrasound is a safe imaging tool that guides percutaneous coronary intervention and significantly reduces the rate of acute kidney injury compared to angiography alone. Patients who have a high chance of experiencing acute kidney injury benefit from using intravascular ultrasound

Development of a highly sensitive point‐of‐care test for African swine fever that combines EZ‐Fast DNA extraction with LAMP detection: Evaluation using naturally infected swine whole blood samples from Vietnam

[Background] While early detection and early containment are key to controlling the African swine fever (ASF) pandemic, the lack of practical testing methods for use in the field are a major barrier to achieving this feat. [Objectives] To describe the development of a rapid and sensitive point-of-care test (POCT) for ASF, and its evaluation using swine whole blood samples for field settings. [Methods] In total, 89 swine whole blood samples were collected from Vietnamese swine farms and were performed the POCT using a combination of crude DNA extraction and LAMP (loop-mediated isothermal amplification) amplification. [Results] The POCT enabled crude DNA to be extracted from swine whole blood samples within 10 min at extremely low cost and with relative ease. The entire POCT required a maximum of 50 min from the beginning of DNA extraction to final judgment. Compared to a conventional real-time PCR detection, the POCT showed a 1 log reduction in detection sensitivity, but comparable diagnostic sensitivity of 100% (56/56) and diagnostic specificity of 100% (33/33). The POCT was quicker and easier to perform and did not require special equipment. [Conclusions] This POCT is expected to facilitate early diagnosis and containment of ASF invasion into both regions in which it is endemic and eradicated

Assessment of myocardial performance index in late-onset fetal growth restriction

The aim of this study is to determine whether the myocardial performance index (MPI) is increased in fetal growth restriction (FGR) fetuses and if increased MPI is related to adverse outcomes of FGR. This is a prospective cross-sectional study. Seventy-three late-onset FGR fetuses and 97 gestational-age matched control fetuses were enrolled in this study. Fetal blood flow parameters including MPI values were measured and compared between the two groups. For the effect of severity of growth restriction on MPI value, they were also compared with < 3rd and 3rd – 10th centile groups. FGR fetuses were divided into two groups by favorable and adverse outcome and ultrasound parameters were compared between these two groups. Moreover, significant factors related to adverse outcomes by univariate analysis were analyzed by multivariate logistic regression analysis. Pulsatility index of umbilical arterial flow (UA-PI), MPI and amniotic fluid index in the FGR were significantly different from the control fetuses. However, no significant difference between < 3rd and 3rd – 10th centile groups was detected in MPI and UA-PI. The increased levels of MPI and UA-PI were independently related with adverse outcome of late-onset FGR pregnancy. In conclusion, MPI values were increased in late-onset FGR pregnancy, and the higher level of MPI could predict adverse outcome as well as the measurement of UA-PI. Clinicians should consider cardiac dysfunction in FGR through increased MPI.departmental bulletin pape
