Objective: The purpose of this study was to conduct a real-world comparison of visceral stent branch related outcomes and patient survival in physician modified endografts (PMEG) versus factory made fenestrated endografts (FMFE).

Methods: After exclusions, 544 PMEG and 1638 FMFE were identified in the Vascular Quality Initiative between 2014 and 2022. The four primary outcomes analyzed with Kaplan Meier (KM) were freedom from mortality, new onset dialysis, visceral ischemia, and visceral stent graft reintervention in follow up.

Superficial temporal artery aneurysms (STAAs) are rare vascular lesions that typically occur after a minor head trauma. The superficial temporal artery is susceptible to injury due to the anatomical position of this vessel over the frontal bone with only relatively thin muscles, the temporalis and frontalis muscles, providing underlying protection. STAAs most commonly present as a painless pulsatile mass.

Periodontal bone defects pose significant challenges in dentistry, necessitating effective treatment strategies. This case report explores the regenerative potential of using a combination of particulate dentin graft (PDG) derived from extracted teeth and recombinant human platelet-derived growth factor (rhPDGF) as bone graft material for the treatment of human periodontal infrabony defects. A 44-year-old male patient presented with a 9 mm pocket probing depth (PPD) and an 8 mm infrabony defect depth mesial to #13, with no gingival recession (GR).

Background: Pertussis-containing vaccines are routinely offered in the UK at 16-32 weeks of gestation and have been shown to be safe and effective, but there remains debate about the best timing for vaccination. Most research into this has focused on serologic immunity, but breastmilk is also important in infant immunity, and the amount of IgA in breastmilk may impact mucosal immunity. It is important to understand if the timing of vaccination in pregnancy affects the concentration of IgA in breastmilk.

Background: This study aimed to see if rifampicin susceptibility can be determined on repeat sampling in pulmonary tuberculosis with a trace call on the first GeneXpert Ultra report.

Methods: This retrospective cohort study included adults with a GeneXpert Ultra trace call in the first respiratory sample from January 2021 to June 2024.

Results: Of the 27 patients with repeat sampling done after the initial trace call, rifampicin susceptibility could be determined in 37% (n=10) of patients.
