Background: A systematic review conducted in 2017 found that Musculoskeletal (MSK) injuries were prevalent among surgeons. Few studies have assessed the role that poor surgical ergonomic practices have had in the development of MSK injuries in plastic and reconstructive surgery (PRS), and fewer specifically in craniofacial surgeons. The impact that MSK injuries have on the emotional well-being of craniofacial surgeons is also not well understood.

Background: Ventral hernia repair is inherently prone to recurrence. This article is a practical review that summarizes the literature on the biomechanics of ventral hernia repairs to provide clinically applicable, evidence-based recommendations to reduce hernia recurrence.

Methods: A practical review of all relevant literature in PubMed concerning the mechanics of ventral hernia repairs and the forces involved was conducted in August 2023.

Background: Evidence-based medicine in plastic surgery is essential to provide optimal care to individual patients. Level of evidence (LOE) and number of citations are metrics used to gauge quality of research and impact within a field, respectively. The objective of this study was to determine an association between LOE and number of citations within recently published articles in (PRS).

Aliphatic hydrocarbons and hydrocarbon-based synthetic polymers are of interest in many fields, but their characterization by mass spectrometric methods is generally limited due to their poor ionizability. Recently, atmospheric pressure photoionization (APPI), combined with halogen anion attachment in negative-ion mode, has drawn attention as a potential method for ionizing various polymers without extensive fragmentation or other unwanted side reactions. In this work, the applicability of halogen anion attachment with APPI was studied using several synthetic polymers, including polyethylene, polypropylene, polyisoprene, and polystyrene, as well as simple -alkanes of various chain lengths.

Background: There is an urgent need to replace fossil-based fuels and chemicals with bio-based, renewable alternatives. Water content is a critical parameter in these liquid products since water affects their quality and properties. However, currently existing methods for bio-oil water content determination have limitations and thus, there is a need to find methods that are versatile, work for a wide water content and sample consistency range repeatably and reliably and are safe for the user and the environment.
