Gestational diabetes diagnosed in third trimester of pregnancy: an observation at a Hospital of Women and Children in Vietnam

Background. Gestational diabetes mellitus (GDM) remains a significant concern within the medical community due to its high risk, as well as its serious side effects on both the mothers and the fetuses. This study aims to assess the prevalence and the risk factors of gestational diabetes mellitus in pregnant women at Da Nang Hospital for Women and Children.Methods. A cross-sectional study was conducted on 706 pregnant women at 2428 weeks of gestation at Da Nang hospital to determine the prevalence of gestational diabetes. Multivariate regression analysis was used to clarify the independent risk factors associated with gestational diabetes. All participants were interviewed and tested for the oral glucose tolerance test (OGTT) to identify the number of gestational diabetes, which was diagnosed according to the American Diabetes Association (ADA) diagnostic criteria in 2014.Results. Gestational diabetes prevalence was 10.2%; categorized by the number of matched diagnostic criteria: 1 criterion: 7.1%; 2 criteria: 2.1%; 3 criteria: 1.0%. There are four independent risk factors for gestational diabetes determined through multivariate regression analysis: maternal age > 30 years (OR = 2.376), a history of gestational diabetes (OR = 12.211), pre-pregnancy BMI ≥ 23 kg/m2 (OR = 10.775), a history of fetal macrosomia > 3800 g (OR = 4.655). The risk of gestational diabetes in the group with risk factors was 6.21 times higher than that in the group with no risk factors.Conclusion. More attention should be paid to the risk factors for gestational diabetes, such as maternal age > 30 years, a history of gestational diabetes, pre-pregnancy BMI ≥ 23 kg/m2, a history of fetal macrosomia > 3800 g in all pregnant women

Viral Metagenomic Analysis of Cerebrospinal Fluid from Patients with Acute Central Nervous System Infections of Unknown Origin, Vietnam.

Central nervous system (CNS) infection is a serious neurologic condition, although the etiology remains unknown in >50% of patients. We used metagenomic next-generation sequencing to detect viruses in 204 cerebrospinal fluid (CSF) samples from patients with acute CNS infection who were enrolled from Vietnam hospitals during 2012-2016. We detected 8 viral species in 107/204 (52.4%) of CSF samples. After virus-specific PCR confirmation, the detection rate was lowered to 30/204 (14.7%). Enteroviruses were the most common viruses detected (n = 23), followed by hepatitis B virus (3), HIV (2), molluscum contagiosum virus (1), and gemycircularvirus (1). Analysis of enterovirus sequences revealed the predominance of echovirus 30 (9). Phylogenetically, the echovirus 30 strains belonged to genogroup V and VIIb. Our results expanded knowledge about the clinical burden of enterovirus in Vietnam and underscore the challenges of identifying a plausible viral pathogen in CSF of patients with CNS infections

Autologous Bone Marrow Stem Cells combined with Allograft Cancellous Bone in Treatment of Nonunion

Autologous cancellous bone graft is currently used as a gold standard method for treatment of bone nonunion. However, there is a limit to the amount of autologous cancellous bone that can be harvested and the donor site morbidity presents a major disadvantage to autologous bone grafting. Embedding viable cells within biological scaffolds appears to be extremely promising. The purpose of this study was to assess the outcome of autologous bone marrow stem cells combined with a cancellous bone allograft as compared to an autologous bone graft in the treatment of bone nonunion. Bone marrow aspiration concentrate (BMAC) was previously produced from bone marrow aspirate via a density gradient centrifugation. Autologous cancellous bone was harvested in 9 patients and applied to the nonunion site. In 18 patients of the clinical trial group after the debridement, the bone gaps were filled with a composite of BMAC and allograft cancellous bone chips (BMAC-ACB). Bone consolidation was obtained in 88.9%, and the mean interval between the cell transplantation and union was 4.6 ± 1.5 months in the autograft group. Bone union rate was 94.4% in group of composite BMAC-ACB implantation. The time to union in BMAC-ACB grafting group was 3.3 ± 0.90 months, and led to faster healing when compared to the autograft. A mean concentration of autologous progenitorcells was found to be 2.43 ± 1.03 (x106) CD34+ cells/ml, and a mean viability of CD34+ cells was 97.97 ± 1.47 (%). This study shows that the implantation of BMAC has presented the efficacy for treatment of nonunion and may contribute an available alternative to autologous cancellous bone graft. But large clinical application of BM-MSCs requires a more appropriate and profound scientific investigations.SCOPUS: ar.jinfo:eu-repo/semantics/publishe

Burden of Hospital Acquired Infections and Antimicrobial Use in Vietnamese Adult Intensive Care Units

Background Vietnam is a lower middle-income country with no national surveillance system for hospital-acquired infections (HAIs). We assessed the prevalence of hospital-acquired infections and antimicrobial use in adult intensive care units (ICUs) across Vietnam. Methods Monthly repeated point prevalence surveys were systematically conducted to assess HAI prevalence and antimicrobial use in 15 adult ICUs across Vietnam. Adults admitted to participating ICUs before 08: 00 a.m. on the survey day were included. Results Among 3287 patients enrolled, the HAI prevalence was 29.5% (965/3266 patients, 21 missing). Pneumonia accounted for 79.4% (804/1012) of HAIs Most HAIs (84.5% [855/1012]) were acquired in the survey hospital with 42.5% (363/855) acquired prior to ICU admission and 57.5% (492/855) developed during ICU admission. In multivariate analysis, the strongest risk factors for HAI acquired in ICU were: intubation (OR 2.76), urinary catheter (OR 2.12), no involvement of a family member in patient care (OR 1.94), and surgery after admission (OR 1.66). 726 bacterial isolates were cultured from 622/1012 HAIs, most frequently Acinetobacter baumannii (177/726 [24.4%]), Pseudomonas aeruginosa (100/726 [13.8%]), and Klebsiella pneumoniae (84/726 [11.6%]), with carbapenem resistance rates of 89.2%, 55.7%, and 14.9% respectively. Antimicrobials were prescribed for 84.8% (2787/ 3287) patients, with 73.7% of patients receiving two or more. The most common antimicrobial groups were third generation cephalosporins, fluoroquinolones, and carbapenems (20.1%, 19.4%, and 14.1% of total antimicrobials, respectively). Conclusion A high prevalence of HAIs was observed, mainly caused by Gram-negative bacteria with high carbapenem resistance rates. This in combination with a high rate of antimicrobial use illustrates the urgent need to improve rational antimicrobial use and infection control efforts
