Background: Peritoneal dialysis is used regularlly in treatment of ESRDs. Residual renal function (RRF) in these patients helps the adequacy of PD therapy very much. Objectives: 1. Study RRF of PD patients at Department of Nephro – Rheumatology, Hue Central Hospital. 2. Search the correlation between RRF and Kt/V. Patients and methods: 35 PD patients at Department of Nephro – Rheumatology, Hue Central Hospital. Measure RRF and Kt/V by formulars that depend on blood, urine and PD fluid samples. Results: Mean RRF of PD patients is 4.36 ± 13.8 ml/minute. There is a close correlation between RRF and Kt/V (r=0.79, p<0.01). Conclusion: RRF in PD patients correlates with Kt/V.

Narrow spectrum series from N-40 to N-120 were established according to ISO 4037:2019. This study was made through experimental measurements and the software modeling toolkit SpekPy v2.0. Experiments were performed to determine Inherent filtration (0.332 & 0.492 mm Al at 100 cm & 250 cm, respectively). The maximum deviation compared to ISO 4037:2019 of the measured HVLs values are not more then 0.10 mm Al and for modeling not exceed 0.09 mm Al; h range 0.91 to 0.97 for experimently and 0.89 to 0.96 for modeling (0.88 - 1, ISO 4037-1:2019). The maximum contribution of scattering is value 4.0% (< 5%, ISO 4037-1:2019). Radiation field uniformity of N-40 to N-120 should list all categories in detail 12.5, 11.0, 10.0, 9.0, 8.5 cm at 100 cm distance; and 35.5, 31.5, 29.0, 26.5, 24.5 cm at 250 cm beam center axis distance. On the basis of ISO 4037:2019, air kerma values at 100 cm and 250 cm have also been determined with uncertainties 3.85% to 5.18% for experimently and 3.41% to 4.19% for modeling (not exceed 10%, ISO 4037:2019). Therefore, the X-ray radiation field has been well established in compliance with the ISO 4037:2019, it can be used for calibrating survey meters and personal dosimeters.

TÓM TẮT Đặt vấn đề: Hội chứng chuyển hóa (HCCH) là rối loạn thường gặp ở người cao tuổi, tuy nhiên số liệu về đặc điểm HCCH ở người sống ở miền núi Việt Nam còn ít. Mục tiêu: Tìm hiểu đặc điểm HCCH ở người đến khám tại bệnh viện đa khoa Kon Tum (2018 - 2019). Phương pháp: Nghiên cứu mô tả ngang 226 Bệnh nhân (BN) mắc HCCH dựa trên đồng thuận của IDF, NHLBI, WHF, IAS và Hiệp hội nghiên cứu về béo phì quốc tế. Kết quả: BN HCCH có thói quen liên quan HCCH (ăn mặn, ăn nhiều mỡ, ăn ít xơ, hút thuốc lá, uống rượu bia, ít hoạt động thể lực đều trên 50%). Nam giới có tỉ lệ hút thuốc lá cao hơn nữ (91,67% so với 22,34% ở nữ). Tỉ lệ gặp các thành phần HCCH là tăng vòng bụng 94,69%, tăng triglyceride 92,48%, tăng glucose máu 87,17%, tăng huyết áp 78,32%, giảm HDL-C 51,33%. Tuổi trung bình BN nam (53,29 ± 16,20) thấp hơn BN nữ (58,56 ± 13,91). Kết luận: HCCH thường gặp ở thành phố Kon Tum (28,3%), ít gặp ở huyện Ia HDrai (1,3%). Nam giới có tỉ lệ tăng triglyceride, tăng huyết áp máu cao hơn và giảm HDL-C thấp hơn so với nữ. Giá trị trung bình huyết áp tối đa, huyết áp trung bình, nồng độ triglyceride ở nam cao hơn ở nữ. Sự khác biệt giá trị trung bình của huyết áp tối thiểu, HDL-C và glucose máu giữa hai giới chưa có ý nghĩa thống kê. ABSTRACT CHARACTERISTICS OF PATIENTS WITH METABOLIC SYNDROME AT KONTUM GENERAL HOSPITAL (APRIL 2018 - APRIL 2019) Background: Metabolic syndrome (Mets) is a common disorder in the elderly, however, data on the characteristics of Mets in people living in mountainous areas of Vietnam are still limited. Objective: To find out the characteristics of Metsin people consulting at Kon Tum General Hospital (2018 - 2019). Methods: Cross - sectional description of 226 patients with Mets were diagnosed according to Joint Interim Statement of the IDF, NHLBI, WHF, IAS; and International Association for the Study of Obesity. Results: The frequency of habits relating to Mets was high with more than 50% of the participants eating salty food, a lot of fat, less fibre, being a smoker, drinker or physical inactivity. Men had a higher smoking rate than women (91.67% compared to 22.34% in women). Raised waist circumference was the most prominent Mets component (94.69%), followed by increased triglyceride (92.48%), hyperglycemia (87,17%), hypertension (78,32%) and reduced high - density lipoprotein cholesterol (HDL-C) (51,33%). The mean age of male patients (53.29 ± 16.20) was lower than that of female patients (58.56 ± 13.91). Conclusions: Mets patients was common in Kon Tum city (28.3%), rare in Ia HDrai district (1.3%). Men had higher rates of elevated triglycerides, hypertension but a lower rate of decreased HDL-C than women. Mean values of systolic blood pressure, mean blood pressure, and triglyceride levels in men higher than women. The difference in mean values of diastolic blood pressure, HDL-C and blood glucose between man and women were not statistically significant.

Background: ESRD is severe result from chronic renal diseases. Treatment of ESRDs is still difficult and expensive. Quality of life of these patients is low. Aims: 1. Study quality of life in patients with ESRD by SF-36 questionaire. 2. Estimate the relationship between SF-36 score and clinical, paraclinical features, Kt/V in the patients with ESRD. Patients-Method: cross-sectional study design. 157 ESRD patients in Department of Nephrology and Rheumatology and Department of Hemodialysis – Hue Central Hospital devided into three groups: conservative treatment (CT), hemodialysis (HD) and CAPD. Study quality of life by using SF-36 questionnaire, version 2.0, Vietnamese. Results: 1. Patients with ESRD have average SF-36 score (physical health: 46.75 ± 15.34; mental health: 47.5 ± 14.66; general health: 49.06 ± 14.61). Conservative group has low SF-36 score (physical health: 32.5 ± 15.9; mental health: 29.67 ± 15.29; general health: 32.35 ± 15.52); CAPD group has average SF-36 score (physical health: 59.75 ± 10.91; mental health: 54.43 ± 7.97; general health: 59.21 ± 8.82); HD group has average SF-36 score (physical health: 51.62 ± 11.94; mental health: 54.9 ± 10.31; general health: 55.2 ± 10.49). 2. In conservative health: SF-36 score has negative correlation with serum BUN, creatininemia, dose of erythropoietin, has positive correlation with Hb, HCO3-. In HD group, there are negative correlations between SF-36 score and blood pressure, BUN, creatininemia, positive correlation with Hb, Albuminemia and Kt/V. In CAPD group, negative correlation between SF-36 score and BUN, creatininemia, positive correlation with Hb. Conclusion: Quality of life by SF-36 score in patients with ESRD is at average level and there is negative correlation between SF-36 score and BUN, creatininemia.
