    Preclinical, Journal:  Co-targeting ASK1 and THR? synergistically improves steatohepatitis and fibrosis in a MASH animal model. (Pubmed Central) -  Mar 19, 2024   
    The cessation of intravenous ritodrine and delivery are the best methods to treat maternal critical status due to fluid overload. GS4997 and MGL3196, when used in combination, have been shown to have a comprehensive effect on MASH by synergistically regulating lipid, inflammation, and fibrosis-related gene expression through co-targeting ASK1 and THR?.
  • ||||||||||  Journal, Adverse events:  Safety of Biological Therapies for Severe Asthma: An Analysis of Suspected Adverse Reactions Reported in the WHO Pharmacovigilance Database. (Pubmed Central) -  Mar 15, 2024   
    The most frequently reported suspected ADRs of asthma biologics in VigiBase confirmed the presence of well-known adverse effects such as general disorders, injection-site reactions, nasopharyngitis, headache and hypersensitivity, while some others (e.g. asthma reactivation or therapeutic failure) could be ascribed to the indication of use. Moreover, the analysis of signals of disproportionate reporting suggests the presence of malignancies, effects on the cardiovascular system, alopecia and autoimmune conditions, requiring further assessment and investigation.
  • ||||||||||  Journal:  Phosphorylation of RyR2 simultaneously expands the dyad and rearranges the tetramers. (Pubmed Central) -  Feb 22, 2024   
    Lastly, the correlation of structural with functional changes suggests that tetramer-tetramer contacts play an important functional role. We thus conclude that both the size of the dyad and the arrangement of the tetramers are linked to the state of the channel tetramer and can be dynamically altered by a ?-adrenergic receptor agonist.
  • ||||||||||  Journal:  Risk assessment in patients with symptomatic and asymptomatic pre-excitation. (Pubmed Central) -  Feb 20, 2024   
    P=N/A
    Sudden loss of pre-excitation during EST has a low NPV in excluding high-risk APs. The EPS with the use of isoproterenol should be considered to accurately assess the risk of patients with pre-excitation regardless of symptoms (ClinicalTrials.gov Identifier: NCT03301935).
  • ||||||||||  Cholesterol Accumulation in Alveolar Macrophages Drives Pulmonary Fibrosis (San Diego Convention Center, Room 30C-E (Upper Level)) -  Feb 20, 2024 - Abstract #ATS2024ATS_5531;    
    Foam cell formation is a result of increased AT2 cell secretion and reduced recycling of cholesterol. Elimination of cholesterol in macrophages through improved macrophage efflux pathways and AT2 recycling is a promising strategy for therapeutic lung fibrosis.
  • ||||||||||  Treprostinil Inhibits Human Lung Fibroblast Matrix Production Via the IP Receptor Independently of cAMP (TDP15) -  Feb 20, 2024 - Abstract #ATS2024ATS_2035;    
    Elimination of cholesterol in macrophages through improved macrophage efflux pathways and AT2 recycling is a promising strategy for therapeutic lung fibrosis. These findings suggest the antifibrotic effects of Treprostinil are mediated through the IP receptor in a cAMP independent manner since both Isoproterenol and PGE2 induce more cAMPi but have less effect on extracellular matrix production as measure by COL1A1 and PAI-1.
  • ||||||||||  tetracycline / Generic mfg.
    Journal:  Comparison of filter membranes in the analysis of 183 veterinary and other drugs by liquid chromatography-tandem mass spectrometry. (Pubmed Central) -  Feb 19, 2024   
    Drug classes represented among the analytes included ?-agonists, ?-lactams, anthelmintics, macrolides, tetracyclines, sulfonamides, tranquilizers, (fluoro)quinolones, anti-inflammatories, nitroimidazoles, coccidiostats, phenicols, and others...In testing by flow-injection analysis, all of the membrane filters were also observed to leach interfering components. Ultimately, filtration was avoided altogether in the final sample preparation approach known as the quick, easy, cheap, effective, rugged, safe, efficient, and robust (QuEChERSER) mega-method, and ultracentrifugation was chosen as an alternative.
  • ||||||||||  Journal:  Aerosol Plumes of Inhalers Used in COPD. (Pubmed Central) -  Jan 9, 2024   
    Plume velocity was lower and spray duration longer for the SMI compared with pMDIs and DPIs. Increasing experimental flow rate was associated with faster plume velocity for DPIs and the SMI, with no or variable impact on plume duration, whereas pMDI aerosol velocity and duration were unaffected by increasing flow rate.
  • ||||||||||  Preclinical, Journal:  Transcriptional changes during isoproterenol-induced cardiac fibrosis in mice. (Pubmed Central) -  Jan 5, 2024   
    A number of known long non-coding RNAs (lncRNAs) and putative novel lncRNAs exhibited differential regulation. In conclusion, our study shows that isoproterenol administration leads to the dysregulation of genes relevant to ECM deposition and cardiac contraction, and serves as an excellent alternate model to the surgical models of heart failure.

    COMPARING DIFFERENT FORMS OF TRIPLE INHALED THERAPY IN REDUCING HOSPITALIZATIONS () -  Jan 4, 2024 - Abstract #SCCM2024SCCM_1884;    
    Furthermore, the study does not account for patients who are noncompliant on triple inhaled therapy and those who were treated in the outpatient setting. A prospective cohort study would be more beneficial in establishing a superior form of triple inhaled therapy.
  • ||||||||||  Journal:  Defining Endogenous Mitochondrial Transfer in Muscle After Rotator Cuff Injury. (Pubmed Central) -  Jan 4, 2024   
    This process may be leveraged therapeutically with ?-agonist treatment and represents an exciting target for improving translational therapies available for rotator cuff muscle degeneration. Promoting endogenous mitochondrial transfer may represent a novel translational strategy to address muscle degeneration after rotator cuff tears.
  • ||||||||||  Trelegy Ellipta (fluticasone furoate/umeclidinium bromide/vilanterol) / GSK, Innoviva, Theravance Biopharma
    Journal, Real-world evidence, Real-world:  Real-World Study of Single-Inhaler Triple Therapy with Fluticasone Furoate/Umeclidinium/Vilanterol on Asthma Control in the US. (Pubmed Central) -  Dec 7, 2023   
    In this real-world study, patients with asthma had significantly lower OCS use, asthma-related exacerbations, and SABA use following treatment initiation with FF/UMEC/VI compared with their pre-treatment period. These results suggest better asthma control following initiation of FF/UMEC/VI in a routine clinical practice setting.

    Review, Journal:  Patient and Clinician Challenges with Anticholinergic Step Therapy in the Treatment of Overactive Bladder: A Narrative Review. (Pubmed Central) -  Nov 27, 2023   
    Medical professionals have called for reform of drug utilization strategies through partnerships that include clinicians and policymakers. This narrative review discusses prescribing patterns for OAB treatment and the effect of switching between drugs, as well as the costs of step therapy and prior authorization on patients and prescribers.
  • ||||||||||  nitroprusside / Generic mfg.
    Preclinical, Journal:  Theophylline-induced endothelium-dependent vasodilation is mediated by increased nitric oxide release and phosphodiesterase inhibition in rat aorta. (Pubmed Central) -  Nov 24, 2023   
    The effects of various inhibitors and endothelial denudation on theophylline-induced vasodilation, and the effect of theophylline on vasodilation induced by NO donor sodium nitroprusside, cyclic guanosine monophosphate (cGMP) analog bromo-cGMP, and ?-agonist isoproterenol in endothelium-denuded aorta were examined...Moreover, theophylline increased stimulatory eNOS (Ser1177) phosphorylation and endothelial calcium levels, but decreased the phosphorylation of inhibitory eNOS (Thr495). These results suggested that theophylline-induced endothelium-dependent vasodilation was mediated by increased endothelial NO release and phosphodiesterase inhibition.
  • ||||||||||  Review, Journal:  Stepwise management of COPD: What is next after bronchodilation? (Pubmed Central) -  Nov 12, 2023   
    In this narrative review, we describe global and country-specific guideline recommendations from Germany, Spain, and Japan and compare these with real-world data on LABA/LAMA and ICS use in clinical practice. We also provide a clinical guide to the use of add-on therapies with LABA/LAMA for different patient phenotypes, including (1) patients still symptomatic (but not exacerbating) despite LABA/LAMA treatment; (2) patients still exacerbating despite LABA/LAMA treatment who have high blood eosinophil counts; and (3) patients still exacerbating despite LABA/LAMA treatment who do not have high blood eosinophils or concomitant asthma.
