A prospective study was carried out on 31 healthy individuals and 32 patients with rheumatoid arthritis at the Military Hospital N0 103 and the Enterology Department of the Police Hospital N0 198. The results showed that: in the patient group, there were increases of number of white blood cells, and lymphocytes, as compared to the control group (p<0.001); there was also wide fluctuation of tumor necrosis factor (TNF-), from 22.41 pg/ml to 1341.62pg/ml. 75% patients had concentration of rheumatoid factor RF≥8 IU/ml (positive). There were agreeable correlations between the number of lymphocytes T, Ta with lymphocytes B at rate r=0.64 (p<0.05); between the number and percentage of Ta-cell with serum concentration of rheumatoid factor (RF) in the patients at low level of r=0.24 and r=0.33

Background: Chronic obstructive pulmonary disease (COPD) remains a major public health problem. It is the fourth leading cause of chronic morbidity and mortality in the United States, and is projected to rank fifth in 2020 in burden of disease caused worldwide. Objective: To research the epidemiology of COPD in the population of Bac Giang city and finding out the risk factors of COPD. Subjects and method: Cross-sectional survey of general population sample of 2,104 men and women with the age \ufffd?0 years in 30 wards of 11 communes of Bac Giang city. Data on respiratory symptoms, diseases, and risk factors were collected. Lung function tests were performed with Spiroanalyzer snoo, Japan. Results and conclusions: The incidence of COPD was 2.3%; in men 3.0% and in women 1.7%. The incidence of simple chronic bronchitis was 6.4%. People who smoked had higher rate of COPD than the others (OR = 2.8). The incidence of smoking in COPD was 55.9%. The three most important risk factors of COPD was the age \ufffd?0; smoking >15 pack/year and medical history of asthma.

Background: Good sleep is important for health and overall quality of life. However, sleep disorders are currently widespread and have particularly serious consequences, especially for students. Objectives: Surveying sleep quality according to the Pittsburgh scale (PSQI) and find out some related factors according to traditional medicine of regular students at the University of Medicine and Pharmacy, Hue University. Methods: A cross-sectional descriptive study on 421 regular students from 10 majors of the Hue University of Medicine and Pharmacy. Results: The percentage of students having poor sleep quality according to the PSQI scale was 57%. According to traditional medicine, heart blood deficiency accounted for the highest proportion with 30.4%, next are the deficiency of heart and spleen (22.1%), kidney yin deficiency (20.8%), qi deficiency of heart and gallbladder (14.6%) and stomach disharmony has the lowest rate with 12.1%. The percentage of students who need treatment with traditional medicine was 52.9%, acupress massage and herbal medicine were the two methods with the highest demand for treatment. Conclusion: Assessing sleep quality according to the PSQI scale the percentage of students with poor sleep quality was 57%. Heart blood deficiency accounted for the highest proportion. The demand for treatment of insomnia by traditional medicine was relatively high.

Backgroud: The aim of this study is to update on antibiotic resistance of common pathogenical bacteria isolated in Hue University of Medicine and Pharmacy Hospital (Hue UMP Hospital). Methodology: Use of the agar disk diffusion method to test the susceptibility to antimicrobial agents of 3709 bacterial strains from infected patients hospitalized in Hue UMP Hospital in 2020 - 2022. Results: Among 3709 strains of pathogenical bacteria isolated, S.aureus was found with the rate of 29.9%, followed by E. coli (24.5%), Pseudomonas aeruginasa (17.8%), Enterococcus spp. (11.8%), Klebsiella spp (9.7%) and Acinetobacter spp (4.1%). The proportion of bacterial isolates has changed, but Staphylococcus aureus is still highest rate. S.aureus is resistant to many antibiotics, but MRSA strains have decreased significantly, from 73.3% in 2020 to 62.5% in 2022. Pseudomonas aeruginosa was resistant to some of the group A recommended antibiotics such as ceftazidime, piperacillin-tazobactam with the rate of 56.6% and 48.7%. The percentage of E. coli with ESBL strains (+) was at 28.2% - 30.3%. Enterococus spp strains are still sensitive to vancomycin (83.1% - 91.9%). The rate of Klebsiella ESBL (+) is only 6.9% to 8.2%. The strains of Acinetobacter spp were highly resistant to Piperacillin (100%) and Ceftriaxone (96.5%) but they are still sensitive to imipenems 70 - 71%, highly sensitive to Doxycillin (95.2%) and Cefotaxime (88.4%). Conclusion: Many bacterial strains are resistant to many commonly antibiotics. Providing timely, regular, and effective management of antibiotic resistance patterns for common pathogenic bacteria in hospitals, will help reduce the risk of bacterial resistance.

Backgrounds: Fecal occult blood testing (FOBT) is commonly used in colorectal cancer screening programs. Many studies have compared different FOBT methods, but the correlation between traditional red cell microscopy and FOBT remains unclear. Objectives: 1) To evaluate the rate of positive FOBT in patients with different disease groups; 2) To compare the sensitivity and specificity of red blood cells detection in fresh stool by microscopy technique and FOBT. Materials and methods: This was a cross-sectional study involving 120 patients from Hue University of Medicine and Pharmacy Hospital who requested a stool test from 4/2021 to 4/2022. Fresh stool samples were examined for the presence of red blood cells using traditional microscopy and FOBT technique. Results: The overall positivity rate of FOBT was 20%, and in the group of gastrointestinal diseases (n = 24), clinical anemia (n = 21), hepatobiliary diseases (n = 26) and other diseases (n = 49), it was 37.5%, 23.8%, 11.5% and 14.3%, respectively. In comparison with the FOBT technique, microscopic RBC detection had a sensitivity of 33.3% and a specificity of 100%. Conclusions: A high rate of fecal occult blood tests was observed in patients with gastrointestinal disorders. Microscopic erythrocyte detection has low sensitivity and many disadvantages compared to the rapid test. This rapid test should be widely used in clinical practice to aid in the diagnosis of gastrointestinal bleeding
