Article Synopsis
  • Hypervirulent Klebsiella pneumoniae (hvKp) is a major cause of severe infections in Vietnam, with a study identifying 14.3% of bloodstream infections caused by this pathogen among 700 samples, along with its presence in healthy adults but not in children.
  • Genetic diversity was noted among hvKp isolates, with 17 different sequence types identified, and about 12.6% carried antimicrobial resistance genes, which can spread between strains through specific plasmids.
  • The study highlights the connection between intestinal carriage and the spread of hvKp infections, emphasizing the need for better surveillance and the use of molecular assays for effective diagnosis and management.

We introduce a comprehensive analysis of several approaches used in stock price forecasting, including statistical, machine learning, and deep learning models. The advantages and limitations of these models are discussed to provide an insight into stock price forecasting. Traditional statistical methods, such as the autoregressive integrated moving average and its variants, are recognized for their efficiency, but they also have some limitations in addressing non-linear problems and providing long-term forecasts.

Unlabelled: Treatment resistance and toxicities remain a risk following chimeric antigen receptor (CAR) T-cell therapy. Herein, we report pharmacokinetics, pharmacodynamics, and product and apheresis attributes associated with outcomes among patients with relapsed/refractory large B-cell lymphoma (LBCL) treated with axicabtagene ciloleucel (axi-cel) in ZUMA-7. Axi-cel peak expansion associated with clinical response and toxicity, but not response durability.

Digital platforms are increasingly playing a crucial role in the digital transformation process, enabling small and medium-sized enterprises to gain a competitive advantage and achieve their business objectives. This research study aims to extend the Technology Acceptance Model by incorporating the Stimulus-Organism-Reaction theory to gain a comprehensive understanding of the factors influencing satisfaction, continued intention to use, and positive electronic word-of-mouth (eWOM) in the context of Food Delivery Apps (FDAs). A quantitative approach was employed, and data were collected through a survey administered to 346 FDA users.

Purpose: Chimeric antigen receptor (CAR) T-cell therapies have shown clinical benefit for patients with relapsed/refractory (R/R) large B-cell lymphoma (LBCL), yet approximately 60% of patients do not respond or eventually relapse. We investigated the safety and feasibility of the CD19-directed CAR T-cell therapy axicabtagene ciloleucel (axi-cel) in combination with the 4-1BB agonist antibody utomilumab as an approach to improve efficacy of CAR T-cell therapy.

Patients And Methods: In phase 1 of the single-arm ZUMA-11 trial, patients with R/R LBCL received a single axi-cel infusion (target dose, 2 × 106 cells/kg) plus utomilumab 10 to 200 mg intravenously every 4 weeks for up to 6 months in a dose-escalation design.

The food delivery apps (FDAs) have facilitated the connection between food service providers and consumers, enabling online ordering through smartphones and offline delivery in Vietnam. The Covid-19 pandemic has significantly impacted the food and beverage industry, accelerating the process of digital transformation and promoting sustainability through online-to-offline service. The usage of FDAs amongst consumers has exhibited a discernible escalation, primarily attributable to its ability to expedite the delivery of food in a hassle-free and convenient manner.

Article Synopsis
  • A study was conducted to evaluate the prevalence of Salmonella Typhi in Ghana, Madagascar, and Ethiopia using DNA and IgM-antibody detection methods, which is important for future surveillance efforts.
  • Real-time PCR and ELISA tests were used to identify the bacteria's DNA and detect specific antigens in blood and biopsies from both febrile and non-febrile patients, revealing varied prevalence rates across sites.
  • The results showed a small percentage of positive cases in febrile individuals and high IgM antibody prevalence in non-febrile individuals, with significant correlations based on factors like age and gender, particularly in Ethiopian sites.

The epidemiology of typhoid fever in Lao People`s Democratic Republic is poorly defined. Estimating the burden of typhoid fever in endemic countries is complex due to the cost and limitations of population-based surveillance; serological approaches may be a more cost-effective alternative. ELISAs were performed on 937 serum samples (317 children and 620 adults) from across Lao PDR to measure IgG antibody titers against Vi polysaccharide and the experimental protein antigens, CdtB and HlyE.

Each level of the coronary artery has different sizes and properties. The primary coronary arteries usually have high contrast to the background, while the secondary coronary arteries have low contrast to the background and thin structures. Furthermore, several small vessels are disconnected or broken up vascular segments.

Typhoid fever is endemic across sub-Saharan Africa. However, estimates of the burden of typhoid are undermined by insufficient blood volumes and lack of sensitivity of blood culture. Here, we aimed to address this limitation by exploiting pre-enrichment culture followed by PCR, alongside routine blood culture to improve typhoid case detection.

Background: Nontyphoidal Salmonella (NTS) organisms are a major cause of gastroenteritis and bacteremia, but little is known about maternally acquired immunity and natural exposure in infant populations residing in areas where NTS disease is highly endemic.

Methods: We recruited 503 pregnant mothers and their infants (following delivery) from urban areas in Vietnam and followed infants until they were 1 year old. Exposure to the dominant NTS serovars, Salmonella enterica serovars Typhimurium and Enteritidis, were assessed using lipopolysaccharide (LPS) O antigen-specific antibodies.

Background: Curcuminoid genes have an important role in the biosynthesis of curcumin, a valuable bioactive compound, in Curcuma species. However, there have not been any reports of these genes in Curcuma zedoaria.

Objective: The present work reports on the isolation of genes encoding enzymes in curcuminoid metabolic pathway and their expression in C.

We are seeing a record number of newly diagnosed skin cancers worldwide, with the incidence of melanoma increasing at a faster rate than almost all other cancers. As clinicians, we will have, by far, the greatest impact on reducing this incidence through better methods of early detection of melanoma and proven prevention methods and techniques. The medical community must enhance its efforts to increase its training of new health care personnel who are capable of diagnosing and treating this record number of patients with skin cancer.

A decline in T-cell responses and a switch to memory T-cell predominance occur with aging. We have used the T-cell receptor (TCR) transgenic mouse model to study age-associated changes in T-cell responses that are a consequence of shifts in subset representation versus changes intrinsic to T cells versus changes in the 'aged' microenvironment. We found that naive transgene-expressing (Tg(+)) CD4(+) T cells from aged mice respond to antigen with reduced interleukin-2 (IL-2) production, decreased cell expansion, and limited differentiation to effectors.
