Education of Parents When a Child Born with an Imperforate Anus; Does It Improve the Health of the Child?  [PDF]
Thi Hoa Chu, Thi Hoa Duong
Open Journal of Pediatrics (OJPed) , 2015, DOI: 10.4236/ojped.2015.51014

Objectives: To describe and investigate the value of an education program for parents of children born with an imperforate anus in order to help them cope with the new situation of having a stoma. A comparison is made with a group of parents following routine hospital. A secondary aim was to illuminate the parents’ feelings and concerns in the first month after the birth of the child. Subjects and methods: The program was tested in 20 Vietnamese mothers of babies born with an imperforate anus; 10 followed an intervention comprising an education program and 10 the ordinary routine hospital. The study design is both qualitative and quantitative. The mothers were interviewed, using open-ended questions, within a week of their child’s birth and then repeatedly for up to one month. Finally, the conditions of children were accessed on their return to the hospital for the second operation after one month of care at home. The qualitative data were subjected to content analysis. Results: All mothers felt sad and worried in the beginning, but this quickly changed to confidence, particularly among mothers in the intervention group who received education. While at home, mothers in both groups had financial concerns, as they were unable to work as much as expected and also had to buy equipment for colostomy care. The mothers in the control group complained about a lack of knowledge and how it affected the care of their child. The mothers in the intervention group, however, felt confident in their caring even at home. When the families returned for the second operation, the children in the intervention group were significantly healthier, had increased more in weight, and had fewer complications and emergency return visits to hospital compared to the control group. In the control group skin problems around the stoma, diarrhea, bleeding or constipation while at home were reported (p < 0.01). Conclusion: The education improved the care at home resulting in healthier children and more confident parents.

Abstract: Streptococcus suis is a pathogen of major economic significance to the swine industry and is increasingly recognized as an emerging zoonotic agent in Asia. In Vietnam, S. suis is the leading cause of bacterial meningitis in adult humans. Zoonotic transmission is most frequently associated with serotype 2 strains and occupational exposure to pigs or consumption of infected pork. To gain insight into the role of pigs for human consumption as a reservoir for zoonotic infection in southern Vietnam, we determined the prevalence and diversity of S. suis carriage in healthy slaughterhouse pigs. Nasopharyngeal tonsils were sampled from pigs at slaughterhouses serving six provinces in southern Vietnam and Ho Chi Minh City area from September 2006 to November 2007. Samples were screened by bacterial culture. Isolates of S. suis were serotyped and characterized by multi locus sequence typing (MLST) and pulse field gel electrophoresis (PFGE). Antibiotic susceptibility profiles and associated genetic resistance determinants, and the presence of putative virulence factors were determined. 41% (222/542) of pigs carried S. suis of one or multiple serotypes. 8% (45/542) carried S. suis serotype 2 which was the most common serotype found (45/317 strains, 14%). 80% of serotype 2 strains belonged to the MLST clonal complex 1,which was previously associated with meningitis cases in Vietnam and outbreaks of severe disease in China in 1998 and 2005. These strains clustered with representative strains isolated from patients with meningitis in PFGE analysis, and showed similar antimicrobial resistance and virulence factor profiles. Slaughterhouse pigs are a major reservoir of S. suis serotype 2 capable of causing human infection in southern Vietnam. Strict hygiene at processing facilities, and health education programs addressing food safety and proper handling of pork should be encouraged.
The impact of degree variability on connectivity properties of large networks
Lasse Leskel?,Hoa Ngo
Computer Science , 2015,
Abstract: The goal of is to study how increased variability in the degree distribution impacts the global connectivity properties of a large network. We approach this question by modeling the network as a uniform random graph with a given degree sequence. We analyze the effect of the degree variability on the approximate size of the largest connected component using stochastic ordering techniques. A counterexample shows that a higher degree variability may lead to a larger connected component, contrary to basic intuition about branching processes. When certain extremal cases are ruled out, the higher degree variability is shown to decrease the limiting approximate size of the largest connected component.
Health and Household Income in Vietnam  [PDF]
Cuong Tat Do, Anh Ngoc Thi Ngo
Theoretical Economics Letters (TEL) , 2013, DOI: 10.4236/tel.2013.36055

This study provides empirical evidence regarding to the relationship between household income and individual health, as well as the correlation between health and education at provincial level. We apply the concept of human health capital theory into models which treat health as a form of human capital in income process and education progress. We employ two datasets, one is Vietnam Household Living Standard Survey wave in 2002, 2004 and 2006, and the other is the dataset for provincial level in the year 1999, 2002 and 2004, in order to make two panels. Constructing panels allow us to exploit “within” variation in health, income and education to figure out the possible unobservable biased estimates of the impact of health on income and education on health in a short period of panel data. Household income is significantly affected by individual health and life expectancy is considerably influenced by education. These findings could be seen as evidence for policy makers in health and education policy in the context of development planning.


Injectable in situ crosslinkable hyaluronan-polyvinyl phosphonic acid hydrogels for bone engineering  [PDF]
Nguyen Thi-Hiep, Dao Van Hoa, Vo Van Toi
Journal of Biomedical Science and Engineering (JBiSE) , 2013, DOI: 10.4236/jbise.2013.68104
Abstract: A novel injectable hydrogel that was synthesized by in situ crosslinking of hyaluronan and polyvinyl phosphonic acid was proposed in this study. Fourier transform infrared spectrum (FT-IR) analysis, scanning electron microscope (SEM), pH measurement, and biodegradation test were used to confirm its characteristics. The results permitted to prove successful crosslinking, observe the inner morphology of hydrogel and pore sizes distribution, and determine the decomposition of hydrogel components during incubation time. Result of pH measurement showed that the pH scale of hydrogel decreased when volume of PVPA increased. As a consequence, it affected the cytotoxicity value, cell proliferation, and cell growth behaviors of each hydrogel. Optical microscope observation showed that chondroblasts cell proliferated well on HA-PVPA hydrogel. Therefore, these results suggest that the new injectable hydrogel is appropriate for bone/cartilage regeneration applications.

Abstract: The 0.8Pb(Zr0.48Ti0.52)O3-0.125Pb(Zn1/3Nb2/3)O3-0.075Pb(Mn1/3Nb2/3)O3 (PZT-PZN-PMnN) + x wt% CuO piezoelectric ceramics, where x = 0.0, 0.05, 0.075, 0.10, 0.125, 0.150, and 0.175, have been fabricated by the conventional solid-state reaction method and the B-site Oxide mixing technique (BO). The effect of CuO on the sinterability, structure, and electrical properties of PZT-PZN-PMnN ceramics was systematically studied. The CuO addition significantly reduced the sintering temperature of the ceramics from 1150°C to 850°C. Experimental results showed that with the doping of CuO, all the ceramics could be well sintered and exhibit a dense, pure perovskite structure. The specimen containing 0.125 wt% CuO sintered at 850°C showed the good electrical properties: the density of 7.91 g/cm3; the electromechanical coupling factor, kp = 0.55 and kt = 0.46; the dielectric constant, ε = 1179; the dielectric loss (tand) of 0.006; the mechanical quality factor (Qm) of 1174; the piezoelectric constant (d31) of 112 pC/N.

PLOS ONE , 2009, DOI: 10.1371/journal.pone.0005973
Abstract: Background Streptococcus suis can cause severe systemic infection in adults exposed to infected pigs or after consumption of undercooked pig products. S. suis is often misdiagnosed, due to lack of awareness and improper testing. Here we report the first fifty cases diagnosed with S. suis infection in northern Viet Nam. Methodology/Principal Findings In 2007, diagnostics for S. suis were set up at a national hospital in Hanoi. That year there were 43 S. suis positive cerebrospinal fluid samples, of which S. suis could be cultured in 32 cases and 11 cases were only positive by PCR. Seven patients were blood culture positive for S. suis but CSF culture and PCR negative; making a total of 50 patients with laboratory confirmed S. suis infection in 2007. The number of S. suis cases peaked during the warmer months. Conclusions/Significance S. suis was commonly diagnosed as a cause of bacterial meningitis in adults in northern Viet Nam. In countries where there is intense and widespread exposure of humans to pigs, S. suis can be an important human pathogen.

Health (Health) , 2016, DOI: 10.4236/health.2016.811113
Abstract: Introduction: Children need intensive care in the first days after open-heart surgery. In some hospitals visits to Intensive Care Units (ICU), are not allowed, even by parents. Aim: The study aimed to illuminate the experiences of children and parents regarding permission or not to visit the ICU. Subjects and Methods: Twenty children aged between 8 and 15 years with planned open-heart surgery, together with their parents, were chosen consecutively to participate in the study. They were divided into two groups. Group 1, followed the routine with no visits by parents allowed to the ICU. Group 2 were allowed such visits. Data were collected through open interviews with parents and children, following an interview guide. Results “Missing” was the overall theme illustrated in the findings, with two major categories; “being seen” and “taking care” being developed. The parents trusted the expert knowledge of the medical staff but Missing was strongly expressed and influenced the feelings within the categories in Group 1. Parents felt they were not seen and the lack of information made them anxious, frightened and feel they were losing control over their parenthood. They asked to see their children only briefly to allay their fears. They knew their children’s needs and thought they could help by taking care of practical issues to improve their well-being. All children in this group felt sad and abandoned. The families in Group 2 felt happy and confident despite not being allowed to stay with children all the time. The parents felt included in their care, which had a positive effect on the children.
Development and Validation of the Self-Esteem Scale of Toulouse (ETES) in Vietnam  [PDF]

Open Journal of Social Sciences (JSS) , 2017, DOI: 10.4236/jss.2017.51010
Abstract: Self-esteem is no longer a new concept in the field of psychology in the whole world in general as well as in Vietnam in particular. There is a rich diversity of self-esteem measurement tools that have been devised and developed. However, in Vietnam, most of the researchers only use the original measurement tools without adapting them to the cultural-social context of Vietnam. Hence, this research aims to evaluate the construction and reliability of an existing popular measurement tool of self-esteem in Europe—which is ETES—in the context of Vietnamese culture. An empirical study was conducted in Vietnam and 1505 valid responses of adolescents were collected. Five sub-scales— which are physical self, emotional self, academic-future self, social self and familial self—were identified through an exploratory factor analysis. The last dimension (familial self) is considered a typical self-esteem area of Vietnamese adolescents. The test-retest reliability demonstrates strong reproducibility of the self-esteem scale and subscales. This new tool is useful for examining how often adolescents in Vietnam evaluate their self-esteem.
