125 alternative treatment providers (ATPs) in 3 provinces Son La, Gia Lai and Song Be were investigated using in-deep interviews. Antimalarial drugs were sold in > 95% of these ATPs. Almost all common antimalarials with different formulation and from different sources were available. Pharmaceutical inspection should be strengthened

The accidents vascular cerebral and it's severe sequelae in movements have changed a patient's gait by certain pattern. To evaluate and correct the gait disorders, the study was conducted aim to objectives: 1) Analyze the gait of normal and of stroke subjects, 2) Find out the correlation between moving balance abilities and joint angles. Method: joint angles at lower extremity in.ambulance of 33 stroke patients and 79 normal subjects of the same age and body height have been analyzed by Skelet software designed by Hanoi Polytechnics Institute authors. Results: the patient's ankle almost in dorsiflexion in walking. The knee has been limited in flexion at swinging and reduced in extension in push of. The hip has been less flexed at swinging and less extended at standing. These joint angle's changes were closely correlated to patient's balancing and moving abilities, (r = 0.67). Conclusion: In case group, the ankle is more in plantar flexion; as well as the knee's and the hip flexion is more notable in patients comparing with control group. The alterations of joint angle are correlative with patient's mobility and balance.

Background: According to traditional medicine, Ganodermataceae has many good effects on such as anti-oxidant, liver protection, sedation, anti-tumor, treatment of dyslipidemia,... Hong chi DaLat \ufffd?[Ganoderma lucidum (HC)] is a species of Ganodermataceae. This species has two strains DL1 and DL2, was grown and used mainly in Da Lat but they had not been fully studied. Objectives: To evaluate the cholesterol lowering effect of HC in cholesterol induced hypercholesterolemic rats. Subjects and method: Rats were given orally the cholesterol 10% with 0.5g/kg body weight/day during 6 consecutive weeks in order to induce hypercholesterolemic rats. The hypocholesterolemic effect of extract of (HC) was investigated at the dose of 4g/kg administered orally in hyperlipidaemic rats after 6 weeks. Results: HC with the dose of 4g/kg significantly decreased plasma triglyceride, total cholesterol, LDL \ufffd?C levels by 24.82%, 27.41% and 54.32% respectively, but increased HDL \ufffd?C by 53.34%. The effect of HC on plasma cholesterol levels with the oral dose of 4g/kg, 12g/kg was equal to each other and to that of cholestyramin at the dose of 1.6g/kg. Conclusion: HC has hypocholesterolemic effect in rats.

Purpose: Simulation teaching refers to the replication of real-life scenarios, enabling students to practice nursing skills and learn actively in a safe environment. It also helps students control their anxiety and fears when caring for real patients. This study investigated the relationships of Vietnamese nursing students’ self-confidence in clinical practice with their satisfaction and self-confidence in simulation-based practice. Methods: This cross-sectional descriptive study included 182 nursing students. The data collection included 2 separate stages with 2 main questionnaires. The Student Satisfaction and Self‐Confidence in Learning Scale was used to measure students’ satisfaction and self‐confidence after learning in the simulation room. The Confidence Scale was used to measure students’ self-confidence when first performing techniques on actual patients. Data were analyzed by descriptive and Pearson correlation statistics. Results: Students’ satisfaction and self-confidence during the simulation course were quite high (mean±standard deviation [SD], 4.06±0.48 and 4.11±0.46 out of 5.0, respectively). In contrast, their confidence when first practicing on a patient was moderate (mean±SD, 3.19±0.62 out of 5.0). Students’ satisfaction showed moderate and weak positive correlations with self-confidence in pre-clinical practice and in clinical practice (r=0.33, P<0.001 and r=0.26, P<0.001, respectively). Conclusion Simulation has become an effective teaching strategy that can help nursing students be well-prepared for clinical placements in Vietnam. An effective nursing education strategy is needed to enhance the satisfaction and self-confidence of nursing students in simulation and then in clinical practice to help achieve professional engagement and development.

Background: Shigella-induced diarrhea has been considered a major health problem leading to high morbidity and mortality. This disease can lead to dire consequences; however, the true burden of the disease, including the costs and sequalae associated with shigellosis is not yet known. Objectives: (1) To describe the health seeking behavior and the way of payment of population when suffering Shigella; (2) To identify and analyze the direct household costs associated with the treatment of diarrhea due to Shigella. Subjects and method: 290 patients of all ages with positive Shigella diarrhea admitted to public health facilities in Nha Trang, Khanh Hoa province in the period from August 2002 to January 2004 were included in the study. The subjects were divided into three age groups, the first 0-5, second 5-18 and the last one was over 18 years old. Patients and their relatives were interviewed at three stages - day 7, day 14 and day 90 - to obtain all the required information. Results: 134 of 290 patients (47%) paid for using the other health care services before admission to the study\u2019s facilities. The average direct cost per episode for the patients at group aged 0-5 was 129,000 VND, group aged 6-18 was 59,267 VND and over 18 years old was 173,531 VND; it was 131.960 VND for three groups. Comparison with the average household expenditure for health care, it was higher in the poorer group and it was lower three times than the richest group. The average direct medical cost per episode was higher the average direct non-medical cost per episode for all groups. Conclusions: The average direct cost per episode of Shigellosis treatment was rather high especially the average direct cost for the treatment at the health facility. It was also high compared with the average expenditure for health per capita so that it becomes large economic burden for households.

Background: This study was conducted on 93 volunteers with type 2 diabetes to investigate the ability of acetylated wheat starch cake containing 32.1% resistant starch to control postprandial blood glucose levels. Material and methods: The study was designed using a crossover, double-blind trial method. During each testing day, after a minimum of 12 hours of overnight fasting, each participant consumed two identical cakes containing either 80 g of acetylated wheat starch or 80 g natural wheat starch with 330ml of water within 15 minutes. Blood glucose levels were measured at baseline, 60 mins (G1), and 120 mins (G2) after ingestion. The predictive value of factors that contribute to the ability of resistant starch to control postprandial blood glucose was determined by the area under the receiver operating characteristic (ROC) curve based on the combined effect of the cake weight-to-BMI ratio (g/m²BMI) and HbA1c. Results: 60 mins and 120 mins postprandial capillary glucose levels after consuming acetylated wheat starch cake (10.4 ± 1.2 và 9.2 ± 1.2 mmol/L, respectively) were significantly lower compared with natural wheat starch cake (13.3 ± 1.8 và 11.2 ± 1.8 mmol/L, respectively) (p < 0.05). For good control of postprandial blood glucose levels, a maximum of 80 g of acetylated wheat starch can be used per serving for patients with type 2 diabetes with HbA1c ≤ 7.25 without blood glucose-lowering medication is required. Conclusion: acetylated wheat starch has better ontroled of postprandial blood glucose compared with natural wheat starch in patients with type 2 diabetes. This is very suitable in the processing of diets including resistant starch for patients with type 2 diabetes for the purpose of both supporting treatment and improving quality of life.
