High specific radioactivity is required for receptor studies with PET. Hereby we wish to report our experience using Nuclear Interface PET Tracer Synthesizer for preparation of Carbon-11 radioligands and module's modifications, which allowed to achieve high specific radioactivity.

Objective: To determine the diagnostic performance and clinical utility of the M4 prediction model and the NICE algorithm managing women with pregnancy of unknown location (PUL).
Design: The study has a superiority design regarding specificity for non-ectopic pregnancy for M4, given that the primary outcome of sensitivity for ectopic pregnancy (EP) is non-inferior in comparison with the NICE algorithm.
Setting: Emergency gynaecology units in Sweden.

Electrolyte imbalance management is crucial in diverse clinical scenarios, with intravenous potassium repletion often required. High-concentration infusions can pose severe complications if extravasation occurs, leading to phlebitis, local tissue damage, or in severe cases, cutaneous necrosis. This risk is elevated in geriatric patients due to factors like reduced tissue elasticity and sensitivity.

Objective: This study aims to analyze anatomical parameters of the transmission route of sigmoid sinus tinnitus (SST) to explore its mechanism and speculate on possible responsible anatomical abnormalities.
Methods: Clinical data were retrospectively collected from SST and sigmoid sinus wall dehiscence (SSWD) patients suggested by temporal bone high resolution computed tomography (HRCT), with and without tinnitus, at the First Affiliated Hospital of Chongqing Medical University from January 2015 to August 2022. Patients were divided into SSWD tinnitus ( = 61), and non-tinnitus ( = 60) groups based on HRCT features.

Background: Plasma NT-proBNP (N-terminal pro-B-type natriuretic peptide) is commonly used to diagnose heart failure with preserved ejection fraction (HFpEF), but its diagnostic performance in the ambulatory/outpatient setting is unknown because previous studies lacked objective reference standards.
Methods: Among patients with chronic dyspnea, diagnosis of HFpEF or noncardiac dyspnea was determined conclusively by exercise catheterization in a derivation cohort (n=414), multicenter validation cohort 1 (n=560), validation cohort 2 (n=207), and a nonobese Japanese validation cohort 3 (n=77). Optimal NT-proBNP cut points for HFpEF rule out (optimizing sensitivity) and rule in (optimizing specificity) were derived and tested, stratified by obesity and atrial fibrillation.

Background: poses a considerable global public health challenge. In Egypt, approximately 60% of the inhabitants in the Northern and Eastern areas of the Nile Delta are affected by this parasite, whereas the Southern region experiences a significantly lower infection rate of 6%.
Aim: Construction of an immune phage display Nbs library based on the VHH framework for selecting -specific Nbs for seeking cost-effective, sensitive, and specific diagnostic tools for rapidly detecting mansoni.
