Background In Viet Nam, tuberculosis (TB) represents a devastating life-event with an exorbitant price tag, partly due to lost income from daily directly observed therapy in public sector care. thus, persons with TB may seek care in the private sector for its flexibility, convenience, and privacy. Our study aimed to measure income changes, costs and catastrophic cost incurrence among TB-affected households in the public and private *** Between October 2020 and March 2022, we conducted 110 longitudinal patient cost interviews, among 50 patients privately treated for TB and 60 TB patients treated by the National TB Program (NTP) in ha Noi, hai Phong and Ho Chi Minh City, Viet Nam. Using a local adaptation of the WHO TB patient cost survey tool, participants were interviewed during the intensive phase, continuation phase and post-treatment. We compared income levels, direct and indirect treatment costs, catastrophic costs using Wilcoxon rank-sum and chi-squared tests and associated risk factors between the two cohorts using multivariate *** The pre-treatment median monthly household income was significantly higher in the private sector versus NTP cohort (USD 868 vs USD 578;P=0.010). However, private sector treatment was also significantly costlier (USD 2075 vs USD 1313;P=0.005), driven by direct medical costs which were 4.6 times higher than costs reported by NTP participants (USD 754 vs USD 164;Pthis resulted in no significant difference in catastrophic costs between the two cohorts (Private: 55% vs NTP: 52%;P=0.675). Factors associated with catastrophic cost included being a single-person household [adjusted odds ratio [(aOR=13.71; 95% confidence interval (CI): 1.36–138.14;P=0.026], unemployment during treatment (aOR=10.86; 95%CI: 2.64–44.60;P<0.001) and experiencing TB-related stigma (aOR=37.90; 95%CI: 1.72–831.73;P=0.021).Conclusions Persons with TB in Viet Nam face similarly high risk of catastrophic costs whether treated in the

Lithium aluminate (LiAlO2) powder was synthesized by sol-gel with EDTA method. The resultant powders were characterized by X-Ray Diffraction (XRD) and Scanning Electronic Microscopy (SEM) techniques. In addition, several thermoluminescence properties of synthesized LiAlO2 powder were reported. The results from X-ray diffraction (XRD), the powder prepared by sol-gel with EDTA method showed pure γ-phase when it was calcined at >900°C. Scanning electron microscopy (SEM) results show that the size of the lithium aluminate particles depended strongly on calcination temperature. The linearity is observed of synthesized LiAlO2 powder by sol-gel with EDTA with regression coefficient (R2) is 0.9971.

Research objective: To study a clinical case that had a complication of subclavian artery bleeding during permanent pacemaker implantation process. Subject and Method: Clinical case report and literature review. Study of a patient had an indication for permanent pacemaker implantation who had complication of subclavian artery bleeding during the procedure. Result: An 84-year-old female patient was admitted to the hospital because of fainting spells with chest pain, on the background of dangerous complex arrhythmias and ischemic heart disease, and was prescribed a pacemaker for this patient. The patient had complication occurred during the procedure, which left subclavian artery bleeding was detected and treated promptly, a cardiac pacemaker was implanted on the right side of the chest, and the patient had a successful endovascular stent cover in the left subclavian artery. Conclude: Subclavian artery bleeding is a rare complication in the procedure of permanent pacemaker implantation, but it can still occur and requires quick detection and timely treatment, needs to be successful in cardiac pacemaker placement and subclavian artery drug-eluting stent cover placement intervention. Individualized patient risk assessment is needed;appropriate and standardized intervention techniques and experience can reduce the occurrence of this variable.
