Background: Hemoglobin is a composition of erythrocyte. They are released from the lysis of erythrocyte. Objectives: to study free hemoglobin concentrations in surgical patients received massive blood transfusion (MBT). Subject and methods: 48 adult patients (male: 31 (64.6%), female: 17 (35.4%), mean age: 36 \xb1 16) with more than 3000ml of storage blood were tested for plasma free hemoglobin. The major reason for MBT were severe trauma (45.8%), the remainder were non - trauma. The change of Hb free was followed in 16 patients at the times of 1500 ml, 2000 ml, 3000 ml storage blood transfused (9 \xb1 3 days). Results: Plasma free hemoglobin was detected after 2,000ml of red cell transfusion and during the first 24h post MBT in 100% cases. Plasma free hemoglobin concentration trended to increase with quantity of transfused blood (0.56 \xb1 0.3 g/dl after 2000 ml, 0.76 \xb1 0.47 g/dl after 3000 ml, and 0.93 \xb1 0.41 g/dl after 5000 ml). There was no correlation between free hemoglobin concentration in plasma of patients with the storage time of blood transfused, and no difference of plasma free hemoglobin concentration between in trauma and non trauma patients. Conclusion: The blood with short time of storage is recommended after 1500ml blood transfusion in these patients. \r\n', u'\r\n', u'

Background: Massive Blood Transfusion is common in surgery, which can save many lives. However, massive blood transfusion in a short time together with other disorders can cause serious side effects and death. Objective: Investigation on the factors related to mortality in surgical patients after massive blood transfusion. Subject and Method: A descriptive study was carried out on 90 patients of massive blood transfusion in Viet Duc hospital. Results: There were 38 cases of death among the 90 patients of massive blood transfusion (42%), in which 97.7% died within 2 to 24 days of hospitalization (caused by multi organ failure). There are no correlation between the deaths, with the units of blood transfused, hypothermia, anemia (Hb) and with platelet counts, APTT, PT, fibrinogen changes, 3 risk factors that correlated significantly with mortality are BE, DIC and age of patients. Conclusion: Acidosis (pH, BE) and hemostasis status should be closely monitored and corrected early to reduce the risks of mortality.

25,873 patients, who came to VietDuc Hospital from Jan 1st 2003 to Dec 31st 2003, were performed HIV antibody tests. Result: among 25,297 samples are tested for HIV antibody, there were 292 cases HIV positive. The numbers of HIV infection among surgical patients in VietDuc Hospital increased day by day, accounted for 1.3% of patients underwent HIV antibody tests, especially the rate of HIV infection in young males (between 20 and 29 years old) was the highest. It is necessary to test HIV for pre-operative patients, special in high-risk people and to pay attention for health equipment, labour assurance for health care workers in hospital

The requirement of bloods in the treatment at the hospital enhanced from 1763 litres (year 1998) to 2783 litres (year 2002) with an average of > 231 litre each month. The use of diverse blood insolated components trended to increase but the quantity was still limited. The transfusion using blood isolated components partly was a solution of safety, of saving the cost and of high efficacy was considered by surgeon in modern transfusion technique. But autotransfusion was still not realized usually.

Background: Secondary injuries are frequent in stroke patients at the acute phase. The early rehabilitation for these patients currently still hasn't received enough attention. Thus it may increase the rate of the secondary disorders. Objectives: To describe the common secondary injuries in stroke patients at the acute phase. Subjects: 90 stroke patients over 18 years old that had experienced hemiplegia less than 30 days, and were treated at Neurology Department, Bach Mai Hospital. Method: Cross-sectional study. Data was analyzed by SPSS software, version 13.0. Results: The rate of the secondary injuries in these patients had reached 80.0%. Among them, the rate of pneumonia is the highest with 30.0%, then urological infections with 17.8%, followed by muscular atrophies, contracture of muscles, stress ulcer, and orthostatic hypotension. There is a close relation between pneumonia and perception impairment: the rate of pneumonia in perception impairment patients was 5.25 folds higher than that in patients without perception impairment (67.9% vs. 12.9%, p< 0.001). Similarly, pneumonia rate in patients with nasogastric tube was 4.2 folds higher than that of patients without nasogastric tube (90.9% vs. 21.5%, p< 0.001). Conclusion: The rate of the secondary injuries in acute stroke patients is high. It is necessary to carry out intensive nursing and rehabilitation for these patients.

Background: Massive blood transfusion is common in surgery: trauma, complicated surgery, organ implantation. Stored blood contains much lactate, ammonia, products of metabolism. These products have negative effects on patient\u2019s metabolic function which may be a cause of death. Objective: To study the change of blood biochemical indexes in surgical patients with massive blood transfusion at Viet Duc hospital. Subjects and method: A prospective study was conducted in the adult patients who had emergency and operation at Viet Duc hospital, from December/2004 to August/2006. All of them were transfused over 3000 ml of blood within 24 hours (pre-operation, intra-operation and post-operation). Results: During the period of study, there were 70 surgical patients with massive blood transfusion: men were more than woman (64%) and the mean age: 38\xb117. The survival rate was significantly improved (57%). The average transfused blood per patient per 24 hours was 3995ml\xb11067ml. There was a decrease in the value of pH, acid-base and HCO3 (the average pH value 7.218\xb10.181, lowest value 6.7). The average value of pH and HCO3\xac was higher in the survival patients than died patients (p<0.05). The mean level of K+ was 3.8\xb10.96mml/l. The increase in the level of K+ had a positive association with the amount of transfused blood. The mean level of Ca++ \xac\xacdecreased under the normal level (0.98mml). Conclusion: It should monitor blood gas and electrolytes continuously in surgical patients with massive blood transfusion in order to identify disorders soon for timely treatment.

Three yeast strains (Hue-1, Hue-8, and Hue-19) with strong heavy metal tolerance were isolated from mangosteen from Hue city, Vietnam. They exhibited identical phenotype and phylogeny. Sequence analysis of the D1/D2 region of the LSU rRNA gene and the internal transcribed spacer (ITS) region demonstrated that the closest relative of these strains is Papiliotrema sp. with 2.12% and 3.55–3.7% divergence in the D1/D2 domain, and ITS domain, respectively. Based on the physiological, biochemical, and molecular data, the three strains belong to a novel species of Papiliotrema genus, for which the namePapiliotrema huenov sp. nov. is proposed. These strains are highly tolerant of heavy metals compared to other yeasts, being able to grow in the presence of 2 mM Pb (II), 2 mM Cd (II), and up to 5 mM Ni (II), but no growth was observed in the presence of 1 mM As (III).

Background: There is a relationship between dermatoglyphic patterns and oral diseases. This study aimed to compare the rate of dermatoglyphic patterns between the caries-active group and the caries-free group. Method: The study was performed on 371 children aged 6 - 12 years at Khe Tre Town primary school, Nam Dong district, Thua Thien Hue province. The children were examined and assessed for the decayed, missing, and filled teeth index. The fingerprints of both the caries-active group and the caries-free group were recorded and then classified and compared between the two groups. Results: The frequency of whorls was found to be more in the caries-active group and the frequency of loops was more in the caries-free group. Conclusion: Dermatoglyphic patterns may be used as a non-invasive tool for screening of early dental caries and guiding future research

Background: Lung cancer is a common cancer with a high mortality rate. The identification of prognostic factors in lung cancer patients in Vietnam is still limited and inconsistent in clinical practice. Objectives: To describe the clinical, paraclinical characteristics and m-LCPI index in patients with primary non-small cell lung cancer and evaluate the factors affecting overall survival in patients with primary non-small cell lung cancer. Methods: Prospective study of 210 cases of non-small cell lung cancer diagnosed with primary non-small cell lung cancer at the Oncology Department of Hue University of Medicine and Pharmacy Hospital and Hue Central Hospital from February 2020 to February 2023. Results: The majority of hospitalizations were at late stages, from stage IIIA (89%), group 3 and 4 in m-LCPI grading scale constituted the majority (80%). Average overall survival at 3 years was 20.0 ± 14 months, and gradually decreased to 54.8%, 40%, and 38.6% after 1 year, 2 years and 3 years, respectively. Regression analysis of COX model between m-LCPI and OS showed statistical significance with m-LCPI 4 (HR = 3.9, 95%CI = 1.57 - 9.69, p = 0.003), while m-LCPI 3 (HR = 2.44, 95% CI 0.97 - 6.13), p = 0.058) had a weak correlation. Conclusion: Our study shows that 38.6% of patients were still alive after 3 years of diagnosis. m-LCPI index is a good predictor of the patients’ overall survival.
