Psychoceuticals have brought benefits to the pharmacotherapeutic management of central nervous system (CNS) illnesses since the 19th century. However, these drugs have potential side effects or lack high response rates. This review covers twenty drugs’ biochemical mechanisms, benefits, risks, and clinical trial reports. For this study, medications from seven psychoceutical organizations were reviewed and evaluated. Nineteen drugs were chosen from the organizations, and one was selected from the literature. The databases used for the search were Pubmed, Google Scholar, and NIH clinical trials. In addition, information from the organizations’ websites and other sources, such as news reports, were also used. From the list of drugs, the most common targets were serotonergic, opioid, and N-methyl-D-aspartate (NMDA) receptors. These drugs have shown promise in psychiatric illnesses such as substance abuse, post-traumatic stress disorder (PTSD), anxiety, depression, and neurological conditions, such as Parkinson’s disease, traumatic brain injury, and neuroinflammation. Some of these drugs, however, are still early in development, so their therapeutic significance cannot be determined. These twenty drugs have promising benefits, but their clinical usage and efficacy must still be explored.
Purpose: To report 2 cases of persistent inflammation associated with human leukocyte antigen-B27 (HLA-B27) after pars plana vitrectomy (PPV) with scleral buckling. Methods: Two cases were analyzed. Results: A 47-year-old man had pars plana vitrectomy (PPV), scleral buckle (SB) placement, and endolaser for a macula-on rhegmatogenous retinal detachment (RRD). A 61-year-old man also had uneventful PPV, SB placement, and endolaser for a macula-off RRD. Postoperatively, both patients reported eye pain and had persistent intraocular inflammation. Both were found to be HLA-B27 positive despite having no previous signs or symptoms that would warrant HLA-B27 testing. Conclusions: Discovering the source of prolonged postoperative inflammation is critical in initiating the correct treatment and removing suspicion of infection. Although intraocular inflammation associated with HLA-B27 does not often present initially after surgery, HLA-B27 testing should be considered in cases of persistent, unexpected postoperative inflammation.
Background and ObjectivesTherapeutic plasma exchange (TPE) is commonly performed using membrane‐based TPE (mTPE) and is prone to filter failure.Design, Setting, Participants, & MeasurementsWe report on 46 patients, with a total of 321 mTPE treatments using the NxStage machine. This was a retrospective study with an aim to evaluate the effect of heparin, pre‐filter saline dilution and the impact of total plasma volume exchanged (< 3 L vs. ≥3 L) on the rate of filter failure. Primary outcome was the overall rate of filter failure. Secondary outcomes included factors that may have indirectly influenced the rate of filter failure, including hematocrit, platelet count, replacement fluid (Fresh Frozen Plasma vs. albumin), and access type.ResultsWe found that treatments that received both pre‐filter heparin and saline had a statistically significant decrease in filter failure rate as compared to those that received neither (28.6% vs. 5.3%, P = .001), and compared to the treatments that received pre‐filter heparin alone (14.2% vs. 5.3%, P = .015). In treatments that received both pre‐filter heparin and saline predilution, we noted a significantly higher filter failure rate when the plasma volume exchanged was ≥3 L as compared to those that had <3 L exchanged (12.2% vs. 0.9%, P = .001).ConclusionsRate of filter failure in mTPE can be reduced by implementing several therapeutic interventions including pre‐filter heparin and pre‐filter saline solution. These interventions were not associated with any clinically significant adverse events. Despite the above‐mentioned interventions, large plasma volume exchanges of ≥3 L can negatively impact filter life.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
