Necrotising fasciitis post-trauma.

The case involves a man in his 30s, otherwise healthy, who developed necrotising fasciitis (NF) after a minor injury. He presented with severe symptoms including intense pain, swelling and fever, which led to a rapid diagnosis confirmed through clinical evaluation and imaging. Immediate surgical intervention was performed to debride the affected tissue, and broad-spectrum antibiotics were administered to address the infection.

Transcriptional modulation of Porphyromonas gingivalis biofilms on titanium-copper implant surfaces.

The healthcare sector is currently concerned about infections caused by Porphyromonas gingivalis biofilms due to their high frequency and incidence, particularly in patients with implanted medical devices. This study investigated biofilm formation and biofilm-related gene expression in P. gingivalis on titanium-copper discs and polycarbonate discs.

NTHi killing activity is reduced in COPD patients and is associated with a differential microbiome.

Chronic obstructive pulmonary disease (COPD) is a chronic lung disease characterized by airway obstruction and inflammation. Non-typeable Haemophilus influenzae (NTHi) lung infections are common in COPD, promoting frequent exacerbations and accelerated lung function decline. The relationship with immune responses and NTHi are poorly understood.

Oncologic Outcomes in Patients with Localized, Primary Head and Neck Synovial Sarcoma.

this study aims to evaluate the survival outcomes of patients suffering from head and neck synovial sarcoma (HNSS), especially in relation to patients with a localized disease at diagnosis. this retrospective chart review includes 57 patients diagnosed with primary HNSS between 1981 and 2020 who presented with a localized disease at diagnosis. Overall survival (OS) from diagnosis, local recurrence-free survival (LRFS), and metastasis-free survival (MFS) from the end of the primary tumor treatment are estimated.

Separating triplet exciton diffusion from triplet-triplet annihilation by the introduction of a mediator.

Triplet-triplet annihilation photon upconversion (TTA-UC) combines the energy of two photons to provide one of higher energy that can be used to drive photochemical or photophysical processes. TTA-UC proceeds at high efficiencies in dilute solution, but in solid state the efficiency drastically reduces. This is because exciton diffusion, compared to molecular diffusion in solid annihilator films, suffers concentration induced quenching, undermining efficient emission.
