Comparison of WALANT and general anaesthesia for trapeziectomy and abductor pollicis longus hammock ligamentoplasty.

Background: Trapeziectomy and abductor pollicis longus hammock ligamentoplasty may be performed in the surgical management of trapeziometacarpal joint osteoarthritis (TMC OA). Several anaesthesia techniques are available for TMC joint surgery, including wide-awake local anaesthesia no tourniquet (WALANT), regional anaesthesia, and general anaesthesia (GA). The aim of this study was to compare the clinical outcomes of trapeziectomy and abductor pollicis longus hammock ligamentoplasty performed under WALANT versus GA.

Describing the Flick Movement Kinematic Biomechanically and Investigating the Effect of Thrower's Ten Exercises in Underwater Hockey Players.

Context: Analyzing flick movement kinematics biomechanically is important to prevent sport-related injuries in underwater hockey players since the aquatic-based flick movement is completely different from land-based flick movements. The study aimed to describe the flick movement kinematic biomechanically in underwater hockey players. Moreover, this study further aimed to investigate the effect of the Thrower's Ten exercises on flick movement kinematics in underwater hockey players.

Assessment of the physiological performance of the invasive oriental shrimp Palaemon macrodactylus from an atypical marine population.

Since 2000, a well-established population of the invasive oriental shrimp Palaemon macrodactylus has been present in fully marine conditions in the southwestern Atlantic Ocean (~38° S). To assess the physiological performance of this atypical population restricted to fully marine conditions, we conducted a laboratory experiment in which individuals were transferred from 35 ‰S (local seawater) to 2 ‰S; 5 ‰S; 10 ‰S; 20 ‰S; 50 ‰S and 60‰ for short (6 h), medium (48 h), and long (>504 h) acclimation periods. We measured the time course response of relevant parameters in the shrimp's hemolymph; activity of Na, K-ATPase (NKA), and V-H-ATPase (VHA); and muscle water content.

[Primary hepatic sarcomatoid carcinoma, an unusual case].

Primary hepatic sarcomatoid carcinoma is a very aggressive tumor, representing 0.4-0.7% of all primary hepatic neoplasms.

Disparate response of decapods to low pH: A meta-analysis of life history, physiology and behavior traits across life stages and environments.

We employed a meta-analysis to determine if the presumed resilience of decapods to ocean acidification extends to all biological aspects, environments, and life stages. Most response categories appeared unaffected by acidification. However, certain fitness-related traits (growth, survival, and, to some extent, calcification) were impacted.
