Integration of mucus and its impact within in vitro setups for inhaled drugs and formulations: Identifying the limits of simple vs. complex methodologies when studying drug dissolution and permeability.

Traditionally, developing inhaled drug formulations relied on trial and error, yet recent technological advancements have deepened the understanding of 'inhalation biopharmaceutics' i.e. the processes that occur to influence the rate and extent of drug exposure in the lungs.

Negative Pressure Wound Therapy in Free Muscle Flaps-Risk or Benefit?

Background:  Application of negative pressure wound therapy (NPWT) on free flaps not only reduces edema but also increases the pressure from outside. The impact of these opposite effects on flap perfusion remains elusive. This study evaluates the NPWT system's influence on macro- and microcirculation of free flaps and edema reduction to better assess the clinical value of this therapy in microsurgical reconstructions.

Global burn care and the ideal burn dressing reloaded - A survey of global experts.

Purpose: Burn care is a highly relevant medical specialty in every part of the world. Different infrastructure, healthcare systems and access to medical supplies lead to different needs, treatment strategies and outcomes. A fundamental tool in a burn care provider's armamentarium is the use of different dressings.

Perfusion Controlled Mobilization after Lower Extremity Free Flaps-Pushing the Limits of Time and Intensity.

 The current standard to gradually adapt the fragile perfusion in lower extremity free flaps to an upright posture is the dangling maneuver. This type of flap training neither fits the orthostatic target load of an upright posture, nor does it assist in mobilizing the patients effectively. In this study, we quantitatively analyzed training effects of an early and full mobilization on flap perfusion.

Less Is More? Impact of Single Venous Anastomosis on the Intrinsic Transit Time of Free Flaps.

 The number of venous anastomoses advisable for a free flap continues to be controversial. Intrinsic transit time (ITT) is the time it takes dye during indocyanine green (ICG) microangiography to travel from the arterial to the venous anastomosis. ITT provides information on blood flow velocity and can predict postoperative circulatory complications.
