Adolescent and young adult (AYA, 15-39 years old) patients with papillary thyroid carcinoma (PTC) experience significant psychological distress and place great importance on obtaining information regarding the disease; however, their demands remain unmet. We aimed to investigate clinicopathological and molecular features of PTC in AYA patients and compare them to those of PTC in older patients (≥40 years). This retrospective study enrolled 1,677 patients diagnosed with PTC from January 2018 to December 2022, with 400 AYA patients and 1,277 older adults.

However, the association between gross findings and genetic alterations in PTC remains unknown. We aimed to investigate the association between clinicopathologic features, including macroscopic features, and the coexistent and -p mutations in patients with PTC.

Despite its importance, the burden of NTS infections in Vietnam is unknown. We conducted a systematic review and a meta-analysis to describe the prevalence and phenotypic antimicrobial resistance (AMR) for NTS over time in Vietnam.

Although NT1 is believed to be an autoimmune disease, the orexinergic neuron-specific antigens targeted by the pathogenic immune response remain elusive. In this study, we evaluated the differential binding capacity of various peptides to serum immunoglobin G from patients with NT1 and other hypersomnolence complaints (OHCs).

However, the impact of this practice on phenotypic AMR is not known. We investigated the prevalence of phenotypic AMR in from chicken ( = 10) and human ( = 11) faecal samples collected from healthy subjects, subject to freeze storage (-20 °C and -80 °C) for 1, 2, 3, and 6 months.

Unfortunately, serious damages could be concentrated to the pinhole and/or pore locations in the porous organic film, resulting in the localized corrosion even when an optimal concentration of organic corrosion inhibitors is used. In this work, SnO nanoparticles are used for producing the more robust barrier layer via the self-migration of nanoparticles, resulting in a higher corrosion resistance, smooth and uniform protective layer, as well as the existence of SnO in the protective layer that could directly affect the high inhibition performance.

Methods: We collected data on AMU and faecal swabs from humans (= 426) and chickens (= 237) from 237 small-scale farms. From each sample, one strain was isolated and tested for its susceptibility against 11 antimicrobials by Sensititre AST.
Colistin is a critically important antimicrobial for human medicine, and colistin-resistant Escherichia coli are commonly found in poultry and poultry products in Southeast Asia. Here, we aim at disentangling the within-farm and outside-farm drivers of colistin resistance in small-scale chicken farms of the Mekong delta of Vietnam. Nineteen Vietnamese chicken farms were followed up along a whole production cycle, during which weekly antimicrobial use data were recorded.

Autodock4 package was preliminary used to predict the binding affinities to BACE1 of more than four thousand compounds presented in the Vietnamese plants (VIETHERB) database. Based on docking results, twenty top-lead compounds having the largest docking energy to BACE1 were rigorously examined using steered molecular dynamics (SMD) simulations.

Methods And Results: Micellar extracts from oregano (Origanum vulgare), cajeput (Melaleuca leucadendra), garlic (Allium sativum), black pepper (Piper nigrum), peppermint (Mentha × piperita L.), tea tree (Melaleuca alternifolia), cinnamon (Cinnamomum zeylanicum) EOs and Product A were investigated for their MIC against Avibacterium endocarditidis (N = 10), Pasteurella multocida (N = 7), Ornitobacterium rhinotracheale (ORT) (N = 10), Escherichia coli (N = 10) and Gallibacterium anatis (N = 10).

Methods: From 2015 to 2018 all patients with suspected recurrent or metastatic radioiodine-negative DTC patients who underwent FDG positron emission tomography/computed tomography (PET/CT) were retrospectively reviewed. Suspected lesions on FDG PET/CT were biopsied and underwent BRAF mutation testing by immunohistochemistry and real-time PCR.
In the Mekong Delta of Vietnam, farmers use large quantities of antimicrobials to raise small-scale chicken flocks, often including active ingredients regarded of "critical importance'" by the World Health Organization. Due to limitations in laboratory capacity, the choice of antimicrobials normally does not follow any empirical criteria of effectiveness. The aim of this study was to highlight non-critically important antimicrobials against which chicken pathogens are likely to be susceptible as a basis for treatment guidelines.

In Experiment 1, we determined that Pig-fertilization medium was superior medium to Tyrode's albumin lactate pyruvate-polyvinyl alcohol medium for IVF and defined the optimum the sperm concentration (1 × 10 sperm/ml). In Experiment 2, we clarified that partial removal of cumulus cells from cumulus-oocyte complexes by hyaluronidase treatment before IVF enhances sperm penetration, whereas complete cumulus removal reduces penetration.

Recently, Vietnam has witnessed the emergence of integrated intensive animal production systems, coexisting with more traditional, locally-sourced wet markets. To date no systematic studies have been carried out to compare health hazards in beef, pork and chicken in different production systems.
