Background: Mitral valve diseases are the most frequent in the cardiac valvular acquired diseases. Valvuloplasty is a very good surgical treatment, also its techniques are difficult. Objective: (1) To describe features of valvular lesion and technique of valvuloplasty. (2) To evaluate the effects of these operations. Subject and Method: 95 cases of mitral valve reconstruction were studied and described retrospectively about pre- operative features, mitral valvuloplasty, and post-operative results. Results: Pre-operative cardiac failure >=2 nd level (NYHA) is 96.8%, with 100% of mitral valve insufficiency, 28.4% associated with valvular stenosis. Mean age of patient is 34.5 +/- 13.2. Each case must do an average 4/15 valvuloplasty techniques, the most frequent are: mitral valvular ring (67.4%), commissurotomy (57.9%), cordage section (45.3%)\u2026 Early post \u2013 operative result is very good: no mortality, mitral valvular function is improved significantly than pre-operative (p<0.001), no severe mitral stenosis or insufficiency. Long-term post operative control (3 months, 3 years, 5 years post \u2013 operation) present the stability of this valvuloplasty with high survival frequency (96.8% in 3 months, 96.2% in 3 years, 93.4% in 5 years), in the 78.5% ranges a good level, re-operation is only required in 3 cases with valvular replacement. Conclusions: Although the difficult technique of valvuloplasty \u2013 especially in rheumatic lesion, mitral valve reconstruction is a good and safe technique to treat the mitral valve diseases.

Background: Flail chest is a severe condition of thoracic trauma, and it requires diagnosis and treatment as soon as possible. From year 2000, we developed an improved technique of open fixation in order to adapt the situations of Vietnam health settings. Objectives: To report preliminary results of application of improved open fixation technique in Viet Duc Hospital from 2001 to 2006. Subjects and method: This descriptive, prospective and retrospective study involved 19 patients with flail chest due to closed thoracic trauma or multiple traumas, treated by open fixation technique. The parameters included features of patients, characteristics of this technique and postoperative progression.Results: Of 19 patients, there were 16 males and 3 females, mean age: 47.8 years. All patients presented obvious signs of flail chest preoperatively, but only 9 cases were treated by open fixation technique and pleural drainage immediately. This technique canbe applied in all sugical settings with single local anaesthesia, and any kind of common surgical threads. The most suitable initial pulled weight is 2000 g. All cases of flail chest required pleural drainage. All patients had good outcomes with open fixation technique, no death. There were 3 patients with postoperative complications, all were severe multiple trauma patients. Conclusion: Improved open fixation technique applied in Viet Duc Hospital is simple, effective and safe, and can be widely used in all surgical settings.

Background: peripheral vascular wounds/trauma is a severe type of surgical emergency, the increasing rate due to the rapid increase of traffic, labor and living accidents. Subjectives and Method: retrospective study, all patients with peripheral vascular wounds/traumas (alone or combination in multiple trauma) were emergency operated at Viet Duc Hospital from January 2004 to June 2006. Results: A total of 310 patients with peripheral vascular injuries in the study, of which accounted for 62.3% of injury, trauma group accounted for 37.7%. The mean age of 30. In first aid, pressed tape accounted for high rate (71.5%). Rate of popliteal vascular trauma due to fractures around the knee accounted for 65.5%, the rate of brachial vascular trauma with fractures around the elbow was 50%. Rate of late diagnosis of arterial trauma was 14.6%, higher than the arterial wounds (2.6%). The rate of ultrasound for forelimbs - where vessels were many wounds, was lower than that for hindlimbs - where vessels were many traumas (44% vs 67.9%). For vascular wounds, more directly vascular connection and more intervention on veins, whereas, for arterial trauma, more vascular graft. Rate of complications was low (7.4%), with no deaths. Conclusions: Overall, the results of emergency surgery for peripheral vascular wounds/trauma were well. No cases was death from vascular lesions, rate of complications was low.

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.

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.
