Background: Innate lymphoid cells (ILCs) are key organizers of tissue immune responses and regulate tissue development, repair, and pathology. Persistent clinical sequelae beyond 12 weeks following acute COVID-19 disease, named post-COVID syndrome (PCS), are increasingly recognized in convalescent individuals. ILCs have been associated with the severity of COVID-19 symptoms but their role in the development of PCS remains poorly defined.

Introduction: The last decade's progress in the treatment of newly diagnosed multiple myeloma has relied on the synergistic combination of agents with different mechanisms of action, basically proteasome inhibitors, immunomodulatory agents, and monoclonal antibodies, in order to achieve the deepest possible response early in the course of treatment. Following induction, several therapeutic strategies aim to improve and maintain response.

Areas Covered: The manuscript reviews available data for the treatment of newly diagnosed multiple myeloma patients with a focus on most recent induction and maintenance combinations and the still important role of autologous stem transplantation.

Background: Over the last decade, there has been a steady increase in the number of children diagnosed with autism spectrum disorder (ASD) on a global scale, impacting all racial and cultural groups. This increase in the diagnostic rate has prompted investigation into a myriad of factors that may serve as early signs of ASD. One of these factors includes the biomechanics of gait, or the manner of walking.

Background: The innervated vastus lateralis flap (IVLF) is a barely used possibility for facial palsy reconstruction because of its thickness compared to the gracilis, latissimus dorsi, and pectoralis minor flaps. The aim of this study is to perform a precise description of the intramuscular distribution of the nerve motor branches and its relationship with the vascular pedicle in order to harvest a segmental muscle flap with the best contractile strength to restore facial reanimation.

Methods: The study was performed on 16 adult cadaver thighs identifying the vastus lateralis muscle and the distribution and relationships of its neurovascular pedicle and branches.

Article Synopsis
  • Idiopathic pulmonary fibrosis (IPF) is a serious and progressive lung disease linked to changes in metabolism, mitochondria, and cellular cleanup processes in lung cells.
  • The microRNA-33 (miR-33) family regulates metabolism and impacts macrophage responses, showing increased levels in lung fluid from IPF patients compared to healthy individuals.
  • By removing miR-33 in macrophages, researchers demonstrated reduced lung fibrosis and inflammation, suggesting that targeting miR-33 could offer a new treatment strategy for IPF.

Background: Facial paralysis reconstruction can be difficult in extensive defects after complex facial or cranial base tumor resection and radiotherapy or when primary smile reanimation attempt has failed. The surgical challenge is more complicated when defects are associated with recipient vessels or nerves depletion. This scenario has not been well described in the literature, and the present article will address the alternatives that plastic surgeons may use in these circumstances.
