Cardiac Tamponade After Video-Assisted Thoracoscopy Surgical Diaphragmatic Plication.

Video-assisted thoracoscopy surgical diaphragmatic plication is the standard of care for diaphragmatic eventration. However, it is associated with complications like injuries to the bowel, liver, spleen, and lung parenchyma. We report life-threatening cardiac tamponade after Video-assisted thoracoscopy surgical diaphragmatic plication.

Predicting pack-ice seal occupancy of ice floes along the Western Antarctic Peninsula.

We explore the habitat use of Antarctic pack-ice seals by analyzing their occupancy patterns on pack-ice floes, employing a novel combination of segmented generalized linear regression and fine-scale (∼ 50 cm pixel resolution) sea ice feature extraction in satellite imagery. Our analysis of environmental factors identified ice floe size, fine-scale sea ice concentration and nearby marine topography as significantly correlated with seal haul out abundance. Further analysis between seal abundance and ice floe size identified pronounced shifts in the relationship between the number of seals hauled out and floe size, with a positive relationship up to approximately 50 m2 that diminishes for larger floe sizes and largely plateaus after 500 m2.

Climate Change Impacts Pair-Bond Dynamics in a Long-Lived Monogamous Species.

Climate change can influence populations of monogamous species by affecting pair-bond dynamics. This study examined the impact of climate on widowhood and divorce, and the subsequent effects on individual vital rates and life-history outcomes over 54 years in a snow petrel (Pagodroma nivea) population. We found that environmental conditions can affect pair-bond dynamics both directly and indirectly.

Severe Tricuspid Regurgitation Leads to Underestimation of the Severity of Mitral Stenosis by Doppler.

• RV volume overload causes septal flattening which leads to reduced transmitral flow. • In severe TR, MVA calculated by Doppler techniques is unreliable. • In MS with concomitant TR, 3D MPR planimetry is reliable for MVA calculation.
