Feasibility of noise-reduction reconstruction technology based on non-local-mean principle in SiPM-PET/CT.

Quantitative values of positron emission tomography (PET) images using non-local-mean in a silicon photomultiplier (SiPM)-PET/computed tomography (CT) system with phantom and clinical images. The evaluation was conducted on a National Electrical Manufacturers Association body phantom with micro-spheres (4, 5, 6, 8, 10, 13 mm) and clinical images using the SiPM-PET/CT system. The signal-to-background ratio of the phantom was set to 4, and all PET image data was obtained and reconstructed using three-dimensional ordered subset expectation maximization, time-of-flight, point-spread function, and a 4-mm Gaussian filter (GF) and clear adaptive low-noise method (CaLM) in mild, standard, and strong intensities.

Does MDMA have treatment potential in sexual dysfunction? A systematic review of outcomes across the female and male sexual response cycles.

Introduction: Sexual health, an integral component of overall well-being, is frequently compromised by common yet underdiagnosed sexual dysfunctions. Traditional interventions encompass pharmaceutical and psychological treatments. Unconventional therapies, like MDMA, offer hope for sexual dysfunction.

SARS-CoV-2 control on a large urban college campus without mass testing.

Objective: A small percentage of universities and colleges conducted mass SARS-CoV-2 testing. However, universal testing is resource-intensive, strains national testing capacity, and false negative tests can encourage unsafe behaviors.

Participants: A large urban university campus.

Population-based hospitalization burden estimates for respiratory viruses, 2015-2019.

Background: Acute respiratory infections (ARIs) result in millions of illnesses and hundreds of thousands of hospitalizations annually in the United States. The responsible viruses include influenza, parainfluenza, human metapneumovirus, coronaviruses, respiratory syncytial virus (RSV), and human rhinoviruses. This study estimated the population-based hospitalization burden of those respiratory viruses (RVs) over 4 years, from July 1, 2015 to June 30, 2019, among adults ≥18 years of age for Allegheny County (Pittsburgh), Pennsylvania.

Emergency Department Communication in Persons Living With Dementia and Care Partners: A Scoping Review.

Objectives: To synthesize published research exploring emergency department (ED) communication strategies and decision-making with persons living with dementia (PLWD) and their care partners as the basis for a multistakeholder consensus conference to prioritize future research.

Design: Systematic scoping review.

Settings And Participants: PLWD and their care partners in the ED setting.
