A study was conducted on 24 patients with advanced chronic renal failure treated at Central Military Hospital 108. Results: The majority of patients with advanced chronic renal failure and periodic dialysis had stable blood pressure in all 7 days follow-up (with 508 measurements). The rate of measurements had systole blood pressure in emergency level (≥ 180mmHg) was very low (4/504 = 0.75%). Less measurements (8.1%) had blood pressure ≥ 160 or ≤90mmHg. The effectiveness of blood pressure medications will be enhanced when using combined treatment and taking at reasonable time (at 6 am, 10 am, 4 pm, 9 pm).

Study was carried out on 22 advanced chronic renal failure, regular dialysis inpatients with hypertension (21 males, 1 female, ages from 25 - 76) treated in Central Military Hospital No.108. All of patients were treated hypertension with combined regimen or one drug followed convention, periodic dialysis 2-3 times per week, 4 hours per 1 time. The study’s time was 7 days. The results: almost of chronic renal failure patients had stable blood pressure, less daytime fluctuation in all of 7 days (with 462 measurements). Very less measurements (8/462) had systole blood pressure in emergency level (≥180 mmHg), less measurements (25/462) had blood pressure, which was not achieved treatment aim due to systole blood pressure at grade 2 (≥160 mmHg). A good efficacy of treatment with hypertension medications achieved by combined treatment at 6 hours, 10 hours, 16 hours and 21 hours of taken times.

Objective: The risk of transmission of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) from schoolchildren to their household and the protective effects of vaccination in these settings remain poorly understood. We assessed the transmission dynamics of schoolchildren with SARS-CoV-2 within their households and the protective effects of coronavirus disease (COVID-19) vaccination among household members in Viet Nam. Methods: We estimated the attack rate, vaccine effectiveness and adjusted risk ratio (aRR) of factors associated with SARS-CoV-2 transmission to household contacts of children confirmed to have COVID-19 who attended three schools in Ha Nam, Phu Tho and Thanh Hoa provinces between September and December 2021 using multivariable regression with household-level random effects. Results: This retrospective cohort study included 157 children infected with SARS-CoV-2 and their 540 household contacts. The attack rate among household contacts was 24.6% (133/540). Overall, vaccine effectiveness among household contacts was 39% (95% confidence interval [CI]: -1 to -63), higher among males than females and higher in adults aged >40 years. COVID-19 transmission was greater among female household contacts compared with males (aRR: 1.35, 95% CI: 0.94 to 1.95), although not statistically significant, and highest among those aged 19–39 years (aRR: 2.51, 95% CI: 1.50 to 4.21). Fully vaccinated household contacts had significantly lower infection risk (aRR: 0.46, 95% CI: 0.26 to 0.84). Discussion: We found substantial onward transmission of SARS-CoV-2 from schoolchildren to household members, and older people were more likely to be protected by vaccination. We recommend that schoolchildren and all household members living with schoolchildren receive at least two doses of a COVID-19 vaccine. Recognizing the role of schoolchildren in the onward transmission of COVID-19 is an important lesson learned by Viet Nam that can help not only in managing other outbreaks but also in protecting schoolchildren by predicting the progress of the outbreak and preparing for a timely response.
