    Journal:  Public health surveillance of new psychoactive substances: recent developments. (Pubmed Central) -  Apr 8, 2024   
    Studies that combine self-report data with toxicology testing in particular are important for capturing unintentional or unknown exposure to NPS including fentanyls and drugs like xylazine. Given the limitations associated with individual indicators of drug use and associated harms, the harmonization of multiple data sources can help present a more complete picture of both trends involving NPS to better inform public health responses.

    Review, Journal:  Nalmefene Hydrochloride: Potential Implications for Treating Alcohol and Opioid Use Disorder. (Pubmed Central) -  Apr 8, 2024   
    The substantially longer half-life of nalmefene and 5-fold higher binding affinity to opioid receptors makes it a superior agent over naloxone in the reversal of high potency synthetic opioids like fentanyl and the emerging nitazenes. Nalmefene presents with a comparable side effect profile to other opioid antagonists and should be considered for further development as a maintenance treatment for opioid and other substance use disorders.

    HCV reinfection among people who use drugs (PWUD) treated for HCV infection: a long-term view (Poster Area) -  Apr 2, 2024 - Abstract #EASLILC2024EASL_ILC_740;    
    Even within a very vulnerable group of individuals with a high risk of HCV reinfection, our program with systematic and comprehensive approaches to reduce the risk of reinfection are associated with rates below 5/100 py. As we treat increasing numbers of individuals who are more vulnerable, strategies such as the ones we have implemented will be important in maximizing the benefits of HCV therapy in these priority populations.

    Long term outcome among HCV-infected people who use drugs (PWUD) successfully treated for HCV infection with Glecaprevir/Pibrentasvir (G/P) (Poster Area) -  Apr 2, 2024 - Abstract #EASLILC2024EASL_ILC_737;    
    Beyond our ability to successfully treat HCV infection in vulnerable inner-city populations, there is a need to maximize the benefit of therapy after a cure has been achieved, especially in the setting of the opioid crisis. Our data suggests that by maintaining these individuals in care post-SVR, our program leads to a reduction in overdose deaths, a systematic detection of reinfection events and prompt re-initiation of HCV therapy when it is required.

    Review, Journal:  Caesarean Delivery: A Narrative Review on the Choice of Neuraxially Administered Opioid and Its Implications for the Multimodal Peripartum Pain Concept. (Pubmed Central) -  Apr 1, 2024   
    Long-acting lipophobic opioids (diamorphine and morphine) have a significant analgesic advantage over short-acting lipophilic opioids (sufentanil and fentanyl)...The question remains as to whether a pain concept that is ideally adapted to a neuraxial short-acting opioid shows benefit to a pain concept that is optimally adapted to neuraxial morphine. If long-acting opioids are used, the timing of each additional component of the multimodal analgesia strategy could ideally be adjusted to this longer duration of action.

    Journal:  Evaluating the rate of reversal of fentanyl-induced respiratory depression using a novel long-acting naloxone nanoparticle, cNLX-NP. (Pubmed Central) -  Mar 29, 2024   
    While cNLX-NP alone may not sufficiently reverse F/FA overdose in a timely manner, mixing free NLX with cNLX-NP can provide a mechanism to both rapidly reverse fentanyl-related effects and maintain extended protection against synthetic opioid toxicity. These data support further development of cNLX-NP as a fast-acting and long-lasting antidote to treat F/FA-induced respiratory depression and overdose, and potentially prevent renarcotization in humans.

    Mechanistic insights into the cellular and molecular mechanisms of an anti-opioid vaccine formulated with a novel Toll-Like receptor (TLR) 7/8 agonist (Exhibit Hall F1; Poster Board Number: B575) -  Mar 29, 2024 - Abstract #IMMUNOLOGY2024IMMUNOLOGY_2069;    
    We applied in vivo and in vitro flow cytometry-based assays to decipher innate immune response and B cell responses associated with adjuvanted fentanyl vaccine formulation. Kinetics of innate immune response post vaccination at the site of injection (muscle) and draining lymph nodes were tracked, as well as the maturation and the activation status of multiple dendritic cell (DC) subsets and other cells, to identify early molecular signatures of vaccine efficacy.

    Journal, Video, Surgery:  Postoperative pulmonary complications in awake video-assisted thoracoscopic surgery: Our 10-year experience. (Pubmed Central) -  Mar 28, 2024   
    According to the ARISCAT scores, the patients with low and intermediate scores were included in Group L (n=173), while those with high scores (n=73) were included in Group H. Sedation protocol consisted of the combination of midazolam and fentanyl with propofol infusion, if necessary...The incidence of pulmonary complications was significantly higher in the pulmonary resection compared to non-pulmonary procedures (p=0.027). Awake video-assisted thoracoscopic surgery seems to be beneficial in reducing the incidence of postoperative pulmonary complications in high-risk patients as assessed with the ARISCAT.
