Platelets are small anucleate cytoplasmic cell bodies released by megakaryocytes in response to various physiologic triggers. Traditionally thought to be solely involved in the mechanisms of hemostasis, platelets have gained much attention due to their involvement wound healing, immunomodulation, and antiseptic properties. As the field of surgery continues to evolve so does the need for therapies to aid in treating the increasingly complex patients seen. With over 14 million obstetric, musculoskeletal, and urological and gastrointestinal surgeries performed annually, the healing of surgical wounds continues to be of upmost importance to the surgeon and patient. Platelet-rich plasma, or platelet concentrate, has emerged as a possible adjuvant therapy to aid in the healing of surgical wounds and injuries. In this review, we will discuss the wound healing properties of platelet-rich plasma and various surgical applications.

Despite an improved understanding of its pathophysiology and a wide range of new treatments, cardiovascular disease (CVD) remains a serious public health issue and the number one cause of mortality in the United States. Conditions that promote chronic systemic inflammation, such as obesity, cancer, and autoimmune and infectious diseases, are now known to play an important role in promoting CVD by inducing the expression of endothelial adhesion molecules and chemokines; these in turn promote leukocyte adherence and infiltration, which initiates and spurs the progression of CVD. In response to this new understanding, researchers are evaluating the potential cardiovascular benefits of new-generation therapies based on endogenous molecules with anti-inflammatory properties. Similarly, targeted approaches that leverage the phenotypic differences between non-inflamed and inflamed endothelia have the potential to selectively deliver therapeutics and decrease the morbidity and mortality of CVD patients. In this review, we discuss the role of inflammation in CVD and explore the therapeutic potential of targeting inflamed vasculature through conventional and biomimetic approaches.

Pneumonectomy is associated with an increased risk of mortality compared with lobectomy or sublobar resections. Despite advancements in thoracic surgery and perioperative management, complete removal of a lung can still represent a challenge for both the surgeon and the patient. Currently, parenchymal-sparing pulmonary resections have equivalent oncologic results to pneumonectomy and therefore, when possible, are favored. However, there are circumstances in which pneumonectomy remains the best oncologic procedure for the patient. Thorough preoperative workup and aggressive postoperative management are mandatory to optimize recovery. In this paper, we review pneumonectomy-related preoperative evaluation, operative techniques, and postoperative management.
