Applying Logistic Regression to Predict Diabetic Nephropathy Based on Some Clinical and Paraclinical Characteristics of Type 2 Diabetic Patients

Today, the incidence of type 2 diabetes mellitus is increasing rapidly on global. This disease is shown with many complications that significantly affect public health. One of them is kidney complications, which have a high incidence among diabetic patients in Vietnam (25.6-33.1%). Age, history of hypertension, and dyslipidemia are considered to be the main risk factors for diabetic nephropathy. Thus, early detection of these factors for kidney damage is significant for diagnosing, monitoring, treatment, and prognosis of diabetic patients. Our descriptive, cross-sectional study conducting on 120 diabetic patients at E Hospital has observed that blood cholesterol levels, HbA1c levels were independently related to eGFR decline below 60 mL/min/1.73m2. From those data, an equation to predict the risk of diabetic kidney disease was estimated as p = with k = Keyword: Type 2 diabetes, Diabetic nephropathy, Risk factor Today, the incidence of type 2 diabetes mellitus is increasing rapidly on global.

Effectiveness of the Management of Drug-drug Interactions in Inpatients through the Drug Interaction Warning System and Clinical Pharmacy Activity at Lao Cai General Hospital

In prescribing practice for inpatients, quickly detecting pairs of drug-drug interactions (DDIs) and providing prompt management when prescribing is of utmost importance in ensuring safe and rational use of drugs. Subjects and research methods: All prescriptions with DDIs warnings for inpatients from 1/1/2021 to 31/3/2021 on the residue reporting system at Lao Cai General Hospital. The research is designed as a cohort study. Results: In 3 months of implementing DDIs surveillance on the system of reporting, there were 214 times of DDIs occurring in 157 inpatients, of which 2 were contraindicated DDIs and 212 severe DDIs. Patients with DDIs have the mean age and number of diseases, respectively: 63.2 ± 17.5 (years) and 4.3 ± 1.87 (diseases). 2 patients with contraindicated DDIs of a clarithromycin-lovastatin pair received direct feedback from pharmacists to agree to cancel the prescription; Patients with severe DDIs are also discussed by pharmacists to agree on the most appropriate management for each patient, such as 77.83% of clinical supervision; 7.08% of replacement medicine; 2.83% of following up more tests; 1.89% of stopping using drugs. Conclusion: The DDIs warning system and clinical pharmacy activity have managed all pairs of DDIs that often occur on inpatients at Lao Cai General Hospital.

Situation Analysis of the Drug Registration in Vietnam from 2009 To 2019

Vietnam is classified into the group of emerging pharmaceutical countries (Pharmerging) according to the classification of IMS Health since 2008. In order to achieve the potential, it is necessary to have a clear understanding of the status of drugs registered for circulation in Viet Nam. However, research on this issue has not been popular, lacked updating, and has not shown continuous change over a long period of time. Therefore, the study is conducted with the desire to provide an overview of the status of drug registration in Vietnam in the period 2009-2019. Classify "Drugs" according to the Law on Pharmacy No. 105/2016/QH13. Pharmaceutical and biological drugs are classified into 27 groups according to ATC codes based on Circular 30/2018/TT-BYT and Vaccine. 19 groups of dosage forms, classified according to the Vietnam Pharmacopoeia V. In the period 2009-2019, Vietnam has 45,801 registered drug registration numbers. In which, domestic drugs with 28,388 numbers (62%). India and South Korea are the 2 countries with the most number of registrations, accounting for 33.9% and 17.3% respectively. Chemico-pharmaceutical finished products registered with 42,245 numbers (92.2%). The group of drugs for treating parasites and anti-infections is the most registered with 27.1%. Oral and parenteral administration, infusion are the two main forms of administration, of which tablets are the most registered dosage form, accounting for 46.4%. Paracetamol is the most registered active ingredient with a total of 2262 registration numbers. Drugs produced domestically have partly met the needs of the people to use drugs, but there is still an imbalance between the pharmacological groups and registered active ingredients. Domestic pharmaceutical enterprises need to increase investment in and research active ingredients and drug groups with few registered numbers. Keywords Drug registration number, active pharmaceutical ingredient, drug registration, period of 2009-2019, Vietnam. References

Gliosarcomas: A Rare Case Report at Viet Duc University Hospital and Review of the Literature

Gliosarcoma is a rare biphasic subtype of glioblastoma with the poor prognosis, principally affects adults; males are more frequently affected, with a male-to-female ratio of 1.8/1. Gliosarcomas are usually located in the cerebral hemispheres, involving the temporal, frontal, parietal, and occipital lobes in decreasing order of frequency. Rarely, gliosarcomas occur in the posterior fossa, lateral ventricles, or spinal cord. A case study: A 32-year-old woman presented with persistent nausea and headache. The preoperative diagnosis was Ependymoma in the right lateral ventricle of the brain. The patient underwent surgical resection of the tumor followed by external radiotherapy, and chemotherapy treatment. Histologic description: The tumor was made up of spindle cells with hyperchromic large nuclei and pink cytoplasm intermingled with large cells with markedly pleomorphic nuclei and abundant cytoplasm along with prominent mitotic activity. Tumour cells revealed positive staining for Ki67 (25%), Oligo2 (focal), GFAP (focal), SMA (focal); negative immunoreactivity for EMA, CD34, Bcl-2, TTF1. Pathological diagnosis: Gliosarcoma, grade IV. Conclusions: Gliosarcoma is an extremely rare neoplasm with an aggressive biological behavior. In terms of histopathology, gliosarcomas are characterized by a biphasic tissue pattern with alternating areas displaying glial and mesenchymal differentiation.

Study on Morphological and Microscopic Characteristics of Abelmoschus sagittifolius (Kurz) Merr. in Vietnam

Sam bo chinh (Abelmoschus sagittifolius (Kurz) Merr.) is a precious medicinal plant that has been exploited and planted in Vietnam for a long time. However, the morphological characteristics of this plant is easy to confuse with other species of the same genus. In addition, the microscopic characteristics and medicinal powder composition of this medicinal plant have not been comprehensively described. The present investigation was aimed to determine the morphological and microscopic characters of Sam bo chinh using comparative morphology, anatomical research and medicinal powder analysis. The complete description of morphological and microscopic characteristics reported in this study will serve as valuable data for the conservation and development of this species in Vietnam. Keywords Morphology, microscopic characteristics, medicinal plant, Abelmoschus sagittifolius.
