Middle East respiratory syndrome (MERS) is a respiratory disease caused by MERS coronavirus. Because of lack of vaccination, various studies investigated the therapeutic efficacy of antiviral drugs and supportive remedies. A systematic literature search from 10 databases was conducted and screened for relevant articles. Studies reporting information about the treatment of MERS coronavirus infection were extracted and analyzed. Despite receiving treatment with ribavirin plus IFN, the case fatality rate was as high as 71% in the IFN-treatment group and exactly the same in patients who received supportive treatment only. Having chronic renal disease, diabetes mellitus and hypertension increased the risk of mortality (P < .05), and chronic renal disease is the best parameter to predict the mortality. The mean of survival days from onset of illness to death was 46.6 (95% CI, 30.5-62.6) for the IFN group compared with 18.8 (95% CI, 10.3-27.4) for the supportive-only group (P = .001). Delay in starting treatment, older age group, and preexisting comorbidities are associated with worse outcomes. In conclusion, there is no difference between IFN treatment and supportive treatment for MERS patients in terms of mortality. However, ribavirin and IFN combination might have efficacious effects with timely administration and monitoring of adverse events. Large-scale prospective randomized studies are required to assess the role of antiviral drugs for the treatment of this high mortality infection.
Intravenous thrombolysis, particularly in a lower dose, is safe and feasible in the treatment of acute IS in our selected Vietnamese population.
Aim We aimed to report the experience of aortic valve reconstruction with autologous pericardium using Ozaki’s procedure in Vietnam. Methods The study included consecutive patients with isolated aortic valve disease who underwent Ozaki’s procedure in our hospital between June 2017 and August 2019. Aortic valve leaflets were reconstructed with autologous pericardium using Ozaki’s procedure. Results Sixty-one patients were included (mean age 55.8 years; 41 were male): 24 with aortic stenosis, 17 with aortic regurgitation, and 20 with both. Of the 61 patients, 16 had a bicuspid aortic valve, and 5 had infective endocarditis. The preoperative peak and mean gradient pressure gradients were 91.7 ± 16.1 mm Hg and 55.3 ± 10.3 mm Hg, respectively. Surgery was performed via a full or partial sternotomy. The procedure was successful in 59 cases. Two patients were converted to prosthetic valve replacement. The aortic crossclamp time was 110.9 ± 20.5 minutes. Intraoperative transesophageal echocardiography showed a mean pressure gradient of 8 ± 2 mm Hg and an aortic valve area of 3.04 ± 0.44 cm2. The mean follow-up period was 18.5 ± 5.7 months. One patient died in hospital due to cardiac tamponade. One patient underwent reoperation due to infective endocarditis 6 months after surgery. Another died at 8 months after surgery due to a mediastinal abscess. The surviving patients had no aortic regurgitation or mild aortic regurgitation at the last follow-up visits. Conclusions Aortic valve reconstruction with autologous pericardium provided good outcomes in our study.
Objectives To determine the prevalence, patterns and determinants of drug‐related problems (DRPs) in prescribing for coronary artery diseases (CADs) in Vietnam. Methods Retrospective cross‐sectional study on outpatients with CADs at a general hospital in Can Tho, Vietnam. DRPs were classified according to Pharmaceutical Care Network Europe definitions. We determined the prevalence and patterns of DRPs. Logistic regression was used to identify the determinants of DRPs. Results Among 683 patients (mean age 63.4; 64.3% female), the prevalence of DRPs was 61.1%. DRPs comprised inappropriate indication (3.5%), inappropriate dosage (22.2%), wrong frequency of use (24.2%), wrong time of taking medications (4.1%), taking medications at the wrong time around meals (19.2%) and drug interactions (19.3%). Patients who took ≥ 5 drugs were more likely to have DRPs (adjusted odds ratio = 1.96; 95% confidence interval = 1.31–2.93). Patients without health insurance were more likely to have inappropriate indication (ORa = 2.93; 95%CI = 1.28–6.70). Taking medications at inappropriate times around meals was common among men (ORa = 1.82; 95%CI = 1.23–2.69) and among those with health insurance (ORa = 1.66; 95%CI = 1.05–2.63). Patients < 65 years old were more likely to be prescribed inappropriate doses (ORa = 1.67; 95%CI = 1.15–2.45). Prescriptions with ≥ 5 drugs were more likely to be taken at inappropriate frequency (ORa = 1.87; 95%CI = 1.09–3.21) and to cause drug interactions (ORa = 6.48; 95%CI = 2.59–16.24). Conclusions DRPs are common among patients with CADs in Vietnam. The number of DRPs increases with the number of drugs in prescriptions. Further studies should identify other potential determinants of DRPs and effective interventions to improve prescribing practice in Vietnam.
There has been marked improvement in leukemia survival, particularly among children in recent time. However, the long-term trends in survival among adult leukemia patients and the associated sex and racial survival disparities are not well understood. We, therefore, evaluated the secular trends in survival improvement of leukemia patients from 1973 through 2014, using Surveillance Epidemiology and End-Result Survey Program (SEER) data. ICD-O-3 morphology codes were used to group leukemia into four types: acute lymphoblastic leukemia (ALL), acute myeloid leukemia (AML), chronic lymphocytic leukemia (CLL), chronic myeloid leukemia (CML). Survival analysis for each leukemia type stratified by race/ethnicity, age, sex was performed to generate relative survival probability estimates for the baseline time period of 1973 through 1979. Hazard ratios (HR) and respective 95% confidence intervals (CIs) for survival within subsequent 10-year time periods by race, age and sex were calculated using Cox proportional hazard models. Of the 83,255 leukemia patients for the current analysis, the 5-year survival of patients with ALL, AML, CLL, and CML during 1973–1979 were 42.0%, 6.5%, 66.5%, and 20.9%, respectively. Compared to the baseline, there were substantial improvements of leukemia-specific survival in 2010–2014 among African-American (81.0%) and Asian (80.0%) patients with CML and among 20–49 year of age with CLL (96.0%). African-American patients, those with AML and those older than 75 years of age had the lowest survival improvements. Asians experienced some of the largest survival improvements during the study period. Others, including African-American and the elderly, have not benefited as much from advances in leukemia treatment.
Human milk lipids provide not only energy but also indispensable bioactive components such as essential fatty acids. To establish the recommended daily intake value and guidelines for infant formula, a reference library of fatty acid composition has been generated from 4 Asian countries (South Korea, China, Vietnam, and Pakistan). Regardless of country, palmitic acid (C16:0), linoleic acid (C18:1), and linolenic acid (C18:2) were the 3 most abundant fatty acids in human milk and account for more than 75% of total fatty acids (total FA). However, there were several considerable differences between fatty acids, particularly n-3 and n-6 (omega-3 and omega-6) groups. Chinese mothers' milk had a high concentration of linoleic acid at 24.38 ± 10.02% of total FA, which may be due to maternal diet. Among the 4 countries, Pakistani mothers' milk contained a high amount of saturated fatty acid (56.83 ± 5.96% of total FA), and consequently, polyunsaturated fatty acids, including n-3 and n-6, were significantly lower than in other countries. It is noteworthy that docosahexaenoic acid (DHA) in Pakistani mothers' milk was 44.8 ± 33.3 mg/L, which is only 25 to 30% of the levels in the other 3 countries, suggesting the need for DHA supplementation for infants in Pakistan. Moreover, the ratio of n-6 to n-3 was also remarkably high in Pakistani mothers' milk (15.21 ± 4.96), being 1.4-to 1.7-fold higher than in other countries. The average DHA: ARA ratio in Asian human milk was 1.01 ± 0.79. Korean mothers' milk showed a high DHA: ARA ratio, with a value of 1.30 ± 0.98, but Pakistani mothers' milk had a significantly lower value (0.42 ± 0.12). The fatty acid compositions and anthropometric data of mother (body mass index, age) did not show any correlation. The obtained data might provide information about human milk compositions in the Asian region that could benefit from setting up recommended nutrient intake and infant formula for Asian babies.
Vitamins are the essential elements for human life and, particularly, for infant health. Human milk is the best source of nutrients for newborns, however, the information of vitamins in Asian maternal milk is still limited. In this study, we have collected 580 Asian maternal milk samples from Korea (n = 254), China (n = 137), Pakistan (n = 92), and Vietnam (n = 97). The vitamin concentrations, including vitamin B-groups (8 vitamins), fat-soluble vitamin (retinol, D, E, K) and lutein in the breast milk of were investigated. The concentration of thiamin (B1), biotin (B7), and folic acid (B9) in mother’s milk of four countries were not considerably different, while riboflavin (B2), pantothenic acid (B5), and pyridoxine (B6) level in Vietnam samples were significantly lower than those in other countries. In contrast, retinol (A) and tocopherol (E) were found to be higher levels in Vietnamese maternal milk. Korean and Chinese maternal milk had low concentrations of retinol that may cause vitamin A deficiency in children. However, Chinese mother’s milk was distinguished with a high concentration of lutein. Pakistani mother’s milk was observed as having a significant problem of folic acid (B9) deficiency. Regardless of the country, vitamin B12, K, and D did not seem to be provided sufficiently through maternal milk. The moderate positive correlations were found between vitamin concentrations in each country and the pooled sample. The data obtained in this study were able to provide vital information to assess the nutritional status of breast milk in Asian countries and contributed to the efforts of ensuring the best nutrition for Asian children.
