Cervical cancer treatment costs and cost-effectiveness analysis of human papillomavirus vaccination in Vietnam: a PRIME modeling study.

BACKGROUND: Cervical cancer is currently the leading cause of cancer mortality among women in South Vietnam and the second leading cause of cancer mortality in North Vietnam. Human papillomavirus (HPV) vaccination has the potential to substantially decrease this burden. The World Health Organization (WHO) recommends that a cost-effectiveness analysis of HPV vaccination is conducted before nationwide introduction. METHODS: The Papillomavirus Rapid Interface for Modeling and Economics (PRIME) model was used to evaluate the cost-effectiveness of HPV vaccine introduction. A costing study based on expert panel discussions, interviews and hospital case note reviews was conducted to explore the cost of cervical cancer care. RESULTS: The cost of cervical cancer treatment ranged from US$368 - 11400 depending on the type of hospital and treatment involved. Under Gavi-negotiated prices of US$4.55, HPV vaccination is likely to be very cost-effective with an incremental cost per disability-adjusted life year (DALY) averted in the range US$780 - 1120. However, under list prices for Cervarix and Gardasil in Vietnam, the incremental cost per DALY averted for HPV vaccination can exceed US$8000. CONCLUSION: HPV vaccine introduction appears to be economically attractive only if Vietnam is able to procure the vaccine at Gavi prices. This highlights the importance of initiating a nationwide vaccination programme while such prices are still available

A prospective multi-center observational study of children hospitalized with diarrhea in Ho Chi Minh City, Vietnam.

We performed a prospective multicenter study to address the lack of data on the etiology, clinical and demographic features of hospitalized pediatric diarrhea in Ho Chi Minh City (HCMC), Vietnam. Over 2,000 (1,419 symptomatic and 609 non-diarrheal control) children were enrolled in three hospitals over a 1-year period in 2009-2010. Aiming to detect a panel of pathogens, we identified a known diarrheal pathogen in stool samples from 1,067/1,419 (75.2%) children with diarrhea and from 81/609 (13.3%) children without diarrhea. Rotavirus predominated in the symptomatic children (664/1,419; 46.8%), followed by norovirus (293/1,419; 20.6%). The bacterial pathogens Salmonella, Campylobacter, and Shigella were cumulatively isolated from 204/1,419 (14.4%) diarrheal children and exhibited extensive antimicrobial resistance, most notably to fluoroquinolones and third-generation cephalosporins. We suggest renewed efforts in generation and implementation of policies to control the sale and prescription of antimicrobials to curb bacterial resistance and advise consideration of a subsidized rotavirus vaccination policy to limit the morbidity due to diarrheal disease in Vietnam

An Autoethnography of an EFL Teacher Stages of Development in Choices of the Best ELT Methodology

This paper attempted to share lived experiences in the teaching career of an EFL teacher in her choices of the best pedagogical methods to be applied in her class. The paper was done under the lens of autoethnography, which was believed to be the most appropriate measure to deal with writing genres such as experiences and narratives in one’s life. The result presented three important stages that an average EFL teacher might undergo. It is hoped that the paper could provide more insights into the teaching life and experiences of the typical EFL teacher and thus be beneficial to novice colleagues in perfecting their profession.

Passion fruit peel pectin/chitosan based antibacterial films incorporated with biosynthesized silver nanoparticles for wound healing application

Antimicrobial pectin/chitosan composite films have potential as wound dressing and food packaging. However, almost biofilms were synthesized through chemical routes, causing eco-unfriendliness, and negative impacts on the environment and human health. Green synthesis of composite films incorporating with biosynthesized AgNPs is therefore necessary to enhance mechanical and antimicrobial activities. This study focused on the influence of biosynthesized AgNPs on characteristics of passion fruit peel pectin/chitosan (P/CH) biofilms. Characterization, mechanical, antimicrobial activities of P/CH/AgNPs biofilms were evaluated. Incorporating AgNPs into P/CH-based films significantly exerted apparent color and optical properties of biofilms. As AgNPs concentration increased, P/CH/AgNPs biofilms had higher water content (20.1%), better water vapor permeability (1.28 × 10–9 g/mm h Pa), but lower mechanical, water solubility (43.98%), swelling (630.29 ± 11.79%) indexes. P/CH/AgNPs biofilms exhibited outstanding antibacterial properties against S. aureus, B. cereus, P. aeruginosa, K. pneumonia. As expected, in vivo results consolidated the evidence of excellent wound closure (100%) of P/CH/AgNPs biofilms after 15 days. Our findings recommend P/CH/AgNPs antibacterial biofilms have promising biomedical applications

XÁC ĐỊNH SỰ CÓ MẶT CỦA CÁC GEN ĐỘC TỐ Ở CÁC CHỦNG Vibrio GÂY BỆNH HOẠI TỬ GAN TỤY CẤP TÍNH TRÊN TÔM THẺ CHÂN TRẮNG TẠI THỪA THIÊN HUẾ

Acute hepatopancreatic necrosis disease (AHPND) is a disease caused by bacteria, with the death ratio up to 100% in the population of Litopenaeus vannamei and Penaeus monodon, and causes great economic losses to many shrimp‐producing countries in Asia. Previous studies have shown that not all strains of Vibrio can cause AHPND because they contain different toxin genes, such as pirAvp, pirBvb, tlh, trh, and tdh. In this study, we evaluate the presence of several toxic genes on Vibrio isolates from Thua Thien Hue province and analyze the sequence of these genes. The results show that in 14 Vibrio strains carrying pirABvp gene, the tlh and toxR genes occur in 14/14 and 7/14 strains, respectively, while none of them have the two genes of trh and tdh. Analyzing the sequence of four DNA fragments shows that these genes have high similarity (98–100%) compared with the genes announced on the Genbank. Genes pirAvp and pirBvp are less different, while tlh and toxR genes are more different. The results could be used for further studies in the production of bioproducts for the prevention and treatment of acute hepatopancreatic necrosis disease in shrimp.Bệnh hoại tử gan tụy cấp tính (Acute Hepatopancreatic Necrosis Disease – AHPND) là một bệnh do vi khuẩn gây ra. Bệnh này dẫn đến tỷ lệ chết lên đến 100% trong quần thể tôm thẻ chân trắng, tôm sú và gây những tổn thất kinh tế đáng kể cho ngành nuôi tôm ở nhiều nước châu Á. Các nghiên cứu trước đây cho thấy không phải chủng Vibrio nào cũng có khả năng gây bệnh do chúng mang các gen độc tố khác nhau. Chúng tôi đã đánh giá sự có mặt của các gen độc tố trên các chủng Vibrio phân lập tại Thừa Thiên Huế đồng thời phân tích trình tự các gen này. Kết quả cho thấy trong 14 chủng Vibrio mang gen pirABvp nghiên cứu, gen tlh xuất hiện ở tất cả các chủng, gen toxR xuất hiện ở 7/14 chủng trong khi đó các gen trh và tdh không xuất hiện trong các chủng vi khuẩn Vibrio phân lập được. Giải trình tự đoạn chỉ thị các gen độc tố cho thấy các gen này đều có độ tương đồng khá cao (98–100%) so với các gen đã công bố trên ngân hàng gen, trong đó 2 gen pirAvp và pirBvp ít sai khác còn các gen tlh và toxR có sự sai khác nhiều hơn. Đây là cơ sở để thực hiện các nghiên cứu tiếp theo trong việc sản xuất các chế phẩm phòng và trị bệnh hoại tử gan tụy cấp tính trên tôm
