In a retrospective cohort study of 1,140 patients harboring methicillin-resistant Staphylococcus aureus, the nasal burden was low in 31%, category 1+ to 2+ in 54%, and category 3+ to 4+ in 15%. There was a significant trend in infection risk with increasing nasal burden (P = 0.007). In multivariate models, high nasal burden remained significantly associated with invasive infection.

Knock-out mouse models and single particle ICP-MS reveal that SP-D and SP-A deficiency reduces agglomeration of inhaled gold nanoparticles in vivo without significant changes to overall lung clearance.
Nanotoxicology

Infection, Inflammation and Repair, Faculty of Medicine, University of Southampton, Southampton, UK.
The role of surfactant proteins A and D (SP-A and SP-D) in lung clearance and translocation to secondary organs of inhaled nanoparticles was investigated by exposing SP-A and SP-D knockout (AKO and DKO) and wild type (WT) mice nose-only for 3 hours to an aerosol of 20 nm gold nanoparticles (AuNPs). Animals were euthanised at 0-, 1-, 7- and 28-days post-exposure. Analysis by inductively coupled plasma mass spectrometry (ICP-MS) of the liver and kidneys showed that extrapulmonary translocation was below the limits of detection.

Nasal septal perforations (NSPs) are a common referral to specialist rhinology practice. A wide range of management options have been described but to be able to offer the most effective treatment modalities to our patients we must be able to capture quantitative data on patient symptom burden accurately and robustly.

The seasonal trends and profiles of respiratory viruses vary by region and season. Due to limited information and the population's vulnerability, we conducted the hospital-based surveillance of respiratory viruses in Eastern Uttar Pradesh.

Department of Otolaryngology, Changhai Hospital, Naval Medical University, Shanghai, China.
Background: There is no consensus regarding the optimal regimen for metastatic nasopharyngeal carcinoma (dmNPC). Locoregional intensity modulated radiotherapy (LRRT) following palliative chemotherapy (PCT) has been shown to prolong the overall survival (OS) and improve the progression-free survival (PFS) of patients with dmNPC, compared with PCT alone. However, patients with a high tumor burden do not benefit from additional LRRT, which inevitably results in toxicity.

Division of Anatomy, Department 1, Faculty of Dentistry, "Carol Davila" University of Medicine and Pharmacy, Bucharest, RO-020021, Romania.
Purpose: The maxillary tuberosity, a critical anatomical landmark in dentistry and maxillofacial surgery, is burdened by terminological confusion. This inconsistency hampers clinical practice and communication across disciplines.
Method: Different resources were used to argue for the necessity of standardising the terminology related to maxillary tuberosity to enhance diagnostic precision and ultimately improve patient outcomes.
