The impact of multiple exposures and movement on the fear response of poultry.

Fear tests are a common research method to assess the affective state of an animal. This study aimed to assess: 1) the impact of repeated exposure to fear tests on fear response and, 2) how the addition of movement to fear stimuli during a novel object test impacts bird fear response. Over two trials, a total of 3,600 Ross 308 birds (1800 birds/trial) were raised until 42 days of age.

Transcatheter tricuspid valve intervention in the presence of a cardiac implantable electronic device; state of the art review.

A large proportion of patients referred for transcatheter tricuspid valve intervention (TTVI) will have the presence of a cardiac implantable electronic device (CIED). In such patients, surgical correction of tricuspid regurgitation (TR) is associated with high rates of morbidity and mortality. Transvenous lead extraction (TLE) could potentially ameliorate CIED-induced TR; however, it carries inherent risks and frequently does not result in TR improvement.

Multiple Valvular Heart Disease in the Transcatheter Era: A State-of-the-Art Review.

Although existing guidelines offer strong recommendations for single valvular dysfunction, the growing prevalence of multiple valvular heart disease (MVHD) in our aging population is challenging the clarity of clinical guidance. Traditional diagnostic modalities, such as echocardiography, face inherent constraints in precisely quantifying valvular dysfunction due to the hemodynamic interactions that occur with multiple valve involvement. Therefore, many patients with MVHD present at a later stage in their disease course and with an elevated surgical risk.

Evaluating the impact of gypsum as a novel bedding material on broiler performance, foot pad health, and fear response.

Flue Gas Desulfurization (FGD) gypsum is a byproduct of the coal-fired power plant process commonly used to remove sulfur dioxide emissions from the flue gas. FGD gypsum has numerous industrial, agricultural, and environmental applications. This study aimed to explore a novel approach involving the use of FGD gypsum combined with different litter treatments as bedding for broiler production.

Balloon rupture during transcatheter aortic valve replacement.

A distinctive complication with balloon-expandable (BE) THV platforms such as the Edwards Sapien (Edwards Lifescience) is the possibility of balloon rupture during THV deployment. Balloon rupture is a rare occurrence that can result in stroke due to fragment embolism, incomplete THV expansion, and/or vascular injury upon retrieval of the balloon. Careful evaluation of preoperative computed tomography is essential to identify high-risk cases.
