Distinct immunological features of oropharyngeal cancer peritumoral tonsillar tissues from inflammatory tonsils and regional lymph nodes: A pilot study.
PLoS One

Division of Otorhinolaryngology and Head and Neck Surgery, Graduate School of Medical Science, Kanazawa University, Kanazawa, Ishikawa, Japan.
Background: Cancer immune responses are generated in secondary lymphoid organs, such as the lymph nodes and tonsils. In the current study, transcriptional profiles of peritumoral tonsillar tissues (PTTs) from oropharyngeal cancers (OPCs) were assessed and compared with those of inflammatory tonsils and regional lymph nodes (rLNs).
Methods: RNA samples of PTTs and rLNs from 13 OPCs, and 4 inflammatory tonsils were subjected to microarray analysis, and differentially expressed genes (DEGs) identified from 730 nCounter Panel immune-related genes.
A preliminary evaluation of a fast, low-cost, and high-throughput nucleic acid extraction method for bacterial microbiota profiling in low-microbial biomass samples.

The respiratory tract is colonized with low-density microbial communities, which have been shown to impact human respiratory health through microbiota-host interactions. However, a lack of fast and cost-effective nucleic acid extraction method for low-microbial biomass samples hinders investigation of respiratory microbiota. Here, we performed a pilot study to assess the suitability of the NAxtra nucleic acid extraction protocol for profiling bacterial microbiota in respiratory samples.

Introduction: The US state of Florida has the third highest rate of HIV as well as high rates of sexually transmitted infections (STIs) indicating critical HIV and STI prevention needs remain unmet. To address gaps in the STI care continuum in people with HIV (PWH), evidence-based interventions were implemented across three Ryan White HIV/AIDS Program (RWHAP) funded clinics in Florida between August 2020-August 2021. Interventions included comprehensive sexual health history (SHH) taking using audio computer-assisted self-interview (ACASI) software, self-collected extragenital gonorrhea and chlamydia testing, and the introduction of a lesbian, gay, bisexual, transgender, and queer (LGBTQ+) welcoming environment.

Children's Hospital, Zhejiang University School of Medicine, Hangzhou, China.
Unlabelled: This study investigated the impact of the coronavirus disease 2019 (COVID-19) pandemic and its associated restrictive measures on infections in children with acute respiratory tract infection. The study aimed to elucidate the epidemiological characteristics of infections before and during the pandemic and following the easing of restrictive measures. Pharyngeal secretions were collected from 1,0174 pediatric patients with acute respiratory infection (ARI) who were admitted to Shaoxing Maternity and Child Health Care Hospital (Shaoxing, China) between May 2018 and December 2023.

Background: Primary Immunodeficiency disorders (PID) can increase the risk of severe COVID-19 and prolonged infection. This study investigates the duration of SARS-CoV-2 excretion and the genetic evolution of the virus in pediatric PID patients as compared to immunocompetent (IC) patients.
Materials And Methods: A total of 40 nasopharyngeal and 24 stool samples were obtained from five PID and ten IC children.
