Background: Rheumatoid arthritis (RA) is a chronic autoimmune disease that causes inflammation and deformity of the joints. Objectives: The study have two purposes: (1) Identify the sensitivity of anti - CCP2 antibodies in rheumatoid arthritis. (2) Identify the correlation between anti - CCP2 antibodies and clinical manifestations, laboratory features of rheumatoid arthritis. Subjects and method: The study was carried out on 70 patients with rheumatoid arthritis from March to July 2006 in rheumatology department at Bach Mai hospital. All they were diagnosed according to the criteria of American College of Rheumatology 1987. Results: Results of study showed that: (1) The sensitivity of anti - CCP2 antibodies is 67.1% (2) The sensitivity of anti - CCP2 antibodies in patients with rheumatoid arthritis is 67.1 % and is as high as the sensitivity of rheumatoid factor. In early stage of disease (the duration of disease under 12 months) the sensitivity of anti - CCP2 antibodies is higher than rheumatoid factor (70% versus 57.5%). There are no significant differences between the group having anti - CCP2 antibodies and the group who did not have anti - CCP2 anti- bodies in any stages of disease about Ritchie index, DAS - 28 index, X - rays, erythrocyte sedimentation rate in the first hour, CRP ratio. Conclusions: The sensitivity of anti - CCP2 antibodies in patients with rheumatoid arthritis is 67.1 %. There is the relation between anti - CCP2 antibodies and the severity of the inflammation and the severity of X - rays.

Background: HIV (human immunodeficiency virus) is the virus that causes AIDS. This virus is passed from one person to another through blood-to-blood and sexual contact. In addition, infected pregnant women can pass HIV to their baby during pregnancy or delivery, as well as through breast-feeding. Objectives:To study the CCR5- 32 and SDF 1-3 A allelic frequence in the HIV -1 infected mothers and their children. Subjects and method: Amplificated on CCR5 and SDF1 gene by PCR and restriction of this fragment length polymorphisme (RLFP) assay for detection of the mutated gene by EcoR1 and Hpall. Results: No mutation of CCR5 was found but only mutation identified at the SDF1 gene. Mutation identified at the SDF1 gene of the mother was: homozygote 2.7% (accounted for 2/37 cases), heterozygote 40.54% (accounted for 15/37 cases) and at the children: homozygote 5.4% (accounted for 1/37 cases), heterozygote 45.95% (accounted for 17/37 cases). The CCR5 chemokin receptor is a co-receptor for M trofic HIV-1 strains, which predominate in the early stage of the HIV disease and SDF-1 natural ligand for the CXCR4 reception. The mutation of these genes protect from HIV-1 infection (slow progression).\r\n', u'Conclusion: It\u2019s necessary to find the mutation of CCR5 and CCR2b related the progression of HIV patients. \r\n', u'

Background: Depression is a mental disorder common worldwide. This study determined the relationships between demographics, health status, household parameters, and depression rates among working-age household heads. Methods: We analyzed data from the Korea Welfare Panel Study Survey conducted in 2020. The 11-item version of the Center for Epidemiologic Studies Depression Scale was used to assess depression. Bivariate analyses and a multiple logistic regression model were used to evaluate the influence of these factors on depression among household heads. Results: The overall prevalence of depression among working-age household heads was 11.69% (19.83% of females and 9.58% of males). The relative risk of depression was 1.71 times higher among the unemployed than among wage earners and 2.18 times higher among those with low income than among those with general income. The relative risk of depression was 3.23 times higher in those with poor health status than in those with good health, and 2.45 times more in those with severe disabilities than in those without disabilities. The rate of depression decreased with education level, number of family members, and presence of children but increased with the presence of the disabled or elderly. Conclusion This study provides a comprehensive overview of depression among working-age household heads and identifies factors strongly associated with depression. These findings may have implications for policymakers to reduce the burden on and improve the quality of life of household heads.

Background: Cystic hygromas is a common abnormal event in obstetrics ultrasound, which is induced by a chromosome disorder; it is also one of the major causes inducing fetus\u2019s congenital malformation. Objective: Determining chromosomal aberration in nuchal cystic hygromas by FISH technique and outcomes the value of factors in prognosis fetuses with cystic hygroma. Subject and methods: 53 fetuses with cystic hygroma, which are detected by ultrasound scan, are analyzed by FISH technique. Compare results of FISH, band G chromosomal analysis, ultrasonographic abnormalities, followed the fetuses. Results: Chromosomal and FISH analysis give the same detection: abnormal chromosomes: 75.46%, the highest rate is Turner syndrome: 50.94%, normal chromosome: 24.53%. Abnormal chromosomal fetuses: multi-malformation, grim prognosis. Cystic hygroma with other malformation in scan: high rate chromosomal aberrations and septated hygroma, Turner syndrome fetuses have large cystic hygroma, 4/6 fetuses with normal chromosome and without other abnormal result scan have resolutions of hygroma in the second trimester, normal birth. Conclusions: Abnormal chromosomes: 75.46%. Prognosis is grim: abnormal chromosomes, other malformations in scan, large cystic, septated hygroma. Prognosis is better: normal chromosomes, without other ultrasonographic abnormalities, small cystic, nonseptated hygroma, resolution of cystic hygroma.

Anaplasma marginale and A. platys were detected and characterized (16S rDNA sequence analysis) from dairy and indigenous cattle, and the latter in domestic dogs in Vietnam. A phylogenetic tree was inferred from 26 representative strains/species of Anaplasma spp. including 10 new sequences from Vietnam. Seven of our Vietnamese sequences fell into the clade of A. marginale and 3 into A. platys, with strong nodal support of 99 and 90%, respectively. Low genetic distances (0.2–0.4%) within each species supported the identification. Anaplasma platys is able to infect humans. Our discovery of this species in cattle and domestic dogs raises considerable concern about zoonotic transmission in Vietnam. Further systematic investigations are needed to gain data for Anaplasma spp. and members of Anaplasmataceae in animal hosts, vectors and humans across Vietnam.

Objectives: The prevalence of posttraumatic stress disorder (PTSD) has increased, particularly among individuals who have recovered from coronavirus disease 2019 (COVID-19) infection. Health literacy is considered a “social vaccine” that helps people respond effectively to the pandemic. We aimed to investigate the association between long COVID-19 and PTSD, and to examine the modifying role of health literacy in this association. Methods: A cross-sectional study was conducted at 18 hospitals and health centers in Vietnamfrom December 2021 to October 2022. We recruited 4,463 individuals who had recovered from COVID-19 infection for at least 4 weeks. Participants provided information about their sociodemographics, clinical parameters, health-related behaviors, health literacy (usingthe 12-item short-form health literacy scale), long COVID-19 symptoms and PTSD (Impact Event Scale-Revised score of 33 or higher). Logistic regression models were used to examine associations and interactions. Results: Out of the study sample, 55.9% had long COVID-19 symptoms, and 49.6% had PTSD.Individuals with long COVID-19 symptoms had a higher likelihood of PTSD (odds ratio [OR], 1.86; 95% confidence interval [CI], 1.63–2.12; p < 0.001). Higher health literacy was associated with a lower likelihood of PTSD (OR, 0.98; 95% CI, 0.97–0.99; p = 0.001). Compared to those without long COVID-19 symptoms and the lowest health literacy score, those with long COVID-19 symptoms and a 1-point health literacy increment had a 3% lower likelihood of PTSD (OR, 0.97; 95% CI, 0.96–0.99; p = 0.001). Conclusion Health literacy was found to be a protective factor against PTSD and modified the negative impact of long COVID-19 symptoms on PTSD.
