Differential impact from individual versus collective misinformation tagging on the diversity of Twitter (X) information engagement and mobility.

Fears about the destabilizing impact of misinformation online have motivated individuals and platforms to respond. Individuals have increasingly challenged others' online claims with fact-checks in pursuit of a healthier information ecosystem and to break down echo chambers of self-reinforcing opinion. Using Twitter (now X) data, here we show the consequences of individual misinformation tagging: tagged posters had explored novel political information and expanded topical interests immediately prior, but being tagged caused posters to retreat into information bubbles.

Separation Surgery Followed by Conformal Postoperative Spine Stereotactic Body Radiation Therapy Does Not Increase Risk of Adjacent Spine Level Progression in the Management of Spine Metastases.

Objectives: To determine if piecemeal separation surgery, in conjunction with smaller treatment volumes utilized with spine stereotactic radiation therapy (S-SBRT), increased the risk of adjacent level progression (ALP).

Methods: We performed a retrospective analysis of a prospectively maintained database of adult spine oncologic patients who underwent SBRT to the spine at University of Michigan from 2010 to 2021. We compared ALP in patients undergoing SBRT who had pretreatment surgery with those who did not.

Comparison of the effects of production and processing parameters on the eating quality of lamb.

While many separate research studies have investigated the effect of production and processing factors on eating quality of lamb, the relative impact of these parameters has been difficult to ascertain. In this study, the effect of eighteen production and processing factors on the eating quality of Welsh Lamb was compared, using meat from 624 lambs and assessments by 1920 UK consumers. Four experimental trials provided a balanced assessment of production and processing factors: muscle, breed type, lamb gender, ageing, finishing diet, season, carcase hanging and packaging method.

The Effect of Perineural Adjuvants on Superficial Parasternal Intercostal Plane Blocks in Cardiac Surgery: A Triple-Blinded Randomized Controlled Feasibility Trial.

Background and aim The study aimed to investigate the effect of adding perineural adjuvants, clonidine and dexamethasone, to local anesthetic in Superficial Parasternal Intercostal Plane (SPIP) blocks. It was designed as a prospective, randomized, triple-blinded, feasibility trial, conducted at a single-center university hospital. The participants included adult patients who were undergoing cardiac surgery via median sternotomy.

Trends in human parainfluenza virus in Scotland before and after the peak of the COVID-19 pandemic, January 2017 to October 2023.

BackgroundHuman parainfluenza viruses (HPIV) commonly cause upper respiratory tract infections, with potential for severe lower respiratory complications. Understanding seasonal increases informs strategies to prevent HPIV spreading.AimWe examined the impact of COVID-19 on HPIV epidemiological and clinical patterns in Scotland using non-sentinel and sentinel surveillance data.
