Enteric Methane Emission from Cattle Grazing Systems with Cover Crops and Legume-Grass Pasture.

This study aims to quantify enteric methane (CH) emission and dry matter intake (DMI) in beef steers under two rotational grazing systems: (i) a mixture of cover crops (vetch + ryegrass + forage radish) (CC) and (ii) alfalfa and fescue pasture (AFP). Eighteen Hereford steers were divided into two groups (nine steers per group), assigned to either the CC or AFP. Methane emissions were measured using the SF tracer technique.

Performance of ChatGPT 3.5 and 4 as a tool for patient support before and after DBS surgery for Parkinson's disease.

Deep brain stimulation (DBS) is a neurosurgical procedure that involves implanting electrodes into specific areas of the brain to treat a variety of medical conditions, including Parkinson's disease. Doubts and questions from patients prior to or following surgery should be addressed in line with the most recent scientific and clinical practice. ChatGPT emerges as an example of how artificial intelligence can be used, with its ability to comprehend and answer medical questions in an understandable way, accessible to everyone.

Training simulator efficacy in developing thoracic and general surgical skills in a residency programme: a pilot study.

Objectives: Virtual training simulators have been introduced in several surgical disciplines to improve residents' abilities. Through the use of the LapSim® virtual training simulator (Surgical Science, Göteborg, Sweden), this study aims to plan an effective learning path in minimally invasive thoracic and general surgery.

Methods: All thoracic and general surgery trainees in their 1st and 2nd year of residency at the University of Insubria were enrolled and randomized into 2 groups: residents undergoing an intensive twice-a-week virtual training programme (group A: n = 8) and those undergoing a once-weekly non-intensive virtual training programme (group B: n = 9).

Long-term follow-up of subthalamic nucleus deep brain stimulation in patients with Parkinson's disease: An analysis of survival and disability milestones.

Background: Data on the long-term survival and incidence of disability milestones after subthalamic nucleus deep brain stimulation (STN-DBS) in Parkinson's disease (PD) is limited.

Objectives: To estimate mortality and assess the frequency/time-to-development of disability milestones (falls, freezing, hallucinations, dementia, and institutionalization) among PD patients post STN-DBS.

Methods: A longitudinal retrospective study of patients undergoing STN-DBS.

Assessment of the 90-day mortality risk score after video-assisted thoracoscopic lobectomy in the Italian VATS Group cohort.

A five-class (A-E) aggregate risk score predicting 90-day mortality after video-assisted thoracoscopic lobectomy for lung cancer, including as independent factors male sex (3 points), carbon monoxide lung diffusion capacity ≤60% (1 point), and operative time ≥150 minutes (1 point), has been recently published. This study aims to assess the effectiveness and reliability of this risk model in a large, independent cohort of patients to confirm its generalizability. From the Italian VATS Group database, we selected 2209 patients [60% males; median age 69 years (interquartile range: 63-74)] who underwent video-assisted thoracoscopic lobectomy for non-small cell lung cancer.
