Functional experiments showed that knockdown of circ_0021093 repressed proliferation, migration and invasion in vitro and tumor growth in vivo by regulating miR-432, while upregulation of circ_0021093 reversed these results. Moreover, miR-432 negatively regulated ANXA2 expression in HCC, and introduction of ANXA2 could abolish overexpression of miR-432-induced effects on HCC cells. Collectively, circ_0021093 boosted HCC progression via regulating proliferation, migration and invasion of HCC cells by acting as competing endogenous RNA to sponge miR-432.Stachydrine is a bioactive alkaloid that has been found to exert tumor-suppressive potential. However, the effect of stachydrine on hepatocellular carcinoma (HCC) has not been previously investigated. In the present study, we investigated the effect of transforming growth factor-β1 (TGF-β1)-induced epithelial-mesenchymal transition (EMT) in HepG2 cells. 1-Methyl-3-nitro-1-nitrosoguanidine compound library chemical Our results showed that stachydrine significantly suppressed TGF-β1-induced HepG2 cell migration and invasion in a dose-dependent manner. Stachydrine prevented TGF-β1-induced EMT in HepG2 cells, as proved by the increased expression level of E-cadherin and decreased expression levels of N-cadherin and vimentin. In addition, stachydrine attenuated TGF-β1-induced upregulation of TGF-β receptor I (TβRI) in both protein and mRNA levels. Further mechanism investigations proved that stachydrine prevented TGF-β1-induced activation of Smad2/3 and phosphoinositol-3-kinase (PI3K)/Akt/mTOR signaling pathways in HepG2 cells. In conclusion, these findings demonstrated that stachydrine prevented TGF-β1-induced EMT in HCC cells through Smad2/3 and PI3K/Akt/mTOR signaling pathways. Thus, stachydrine might be a potential therapeutic agent for the treatment of HCC.Osimertinib is a third-generation epidermal growth factor receptor-tyrosine kinase inhibitor (EGFR-TKI) used both as the first-line treatment of EGFR-mutated non-small cell lung cancer patients and in second-line after T790M-positive disease progression to first- or second-generation TKIs. Unfortunately, patients unavoidably experience disease progression to osimertinib and the current research is focused on resistance mechanisms and the relative therapeutic strategy. We report the case of a patient with advanced EGFR-mutated (exon 19 deletion and T790M-positive) non-small cell lung cancer who developed disease progression to osimertinib characterized by the loss of T790M concurrently with the emergence of G724S EGFR mutation, which was tackled by subsequent afatinib treatment. Next-generation sequencing molecular study of rebiopsy at time of progression to osimertinib revealed the persistence of EGFR exon 19 deletion, loss of T790M with a new G724S EGFR mutation; other concomitant mechanisms were excluded. Retrospective analysis of cell-free DNA revealed the emergence of G724S EGFR mutation four months before the radiologically-proven disease progression. The patient, after chemotherapy, was treated with afatinib with clinical and radiological benefit. Our case report contributes to increase the knowledge on acquired resistance mechanisms to osimertinib treatment, and it shows, for the first time, the efficacy of afatinib in the case of T790M loss and emergence of G724S EGFR mutation.
To estimate treatment and postpartum health care utilization among pregnant persons with opioid use disorder (OUD) in Vermont and Maine.
Vermont's and Maine's All Payer Claims Databases were used to identify deliveries 2010 to 2018 that were paid for, in part, by Medicaid. OUD was identified among pregnant persons if they had any claim with an OUD-diagnosis code (ICD-9/10) or medication for addiction treatment (MAT) code during the 5 months before delivery event. Consistent and inconsistent MAT were compared to no MAT on the rate of hospitalizations and emergency department (ED) visits in the first 12 months' postpartum using negative binomial regression.
From 2010 through 2018, 27,652 deliveries in Vermont and 43,480 deliveries in Maine were among persons insured by Medicaid. The prevalence of OUD among pregnant persons increased from 6.7% to 11.6% in Vermont and from 7.4% to 11.0% in Maine. Among pregnant persons with OUD in 2018, 57% had consistent MAT in Vermont and 50% had consistent MAT in Maine; approximately 32% and 27% were not in treatment in Vermont and Maine, respectively. In Maine, consistent MAT was associated with a 47% lower rate of hospitalization and 37% to 46% lower rates of ED visits when compared to those without MAT; in Vermont, those with consistent buprenorphine treatment had a 30% lower rate of ED visits.
Medicaid data from Vermont and Maine suggests that medication for addiction treatment for opioid use disorder during pregnancy reduces emergency health care utilization in the first year postpartum.

As restrictions now begin to loosen, there is an opportunity to transition towards a new treatment structure informed by the experience from both the current public health crisis and precrisis operations. However, there is currently limited information on how best to do so, leaving many providers and specialty programs searching for answers. The permanent integration of recent regulatory changes into routine clinical practice, specifically regarding prescribing flexibility and use of telehealth, is yet to be determined, but implementation experience highlights the adaptability within this field of medicine. Providing patients with a spectrum of care that is both clinically informed and technologically supported should be at the forefront as we settle into a postcrisis world.
To elucidate the main latent classes of substances detected among overdose decedents, and latent class associations with age, sex, race, and jurisdiction of death in Maryland.
We used toxicology data from the Office of the Chief Medical Examiner of Maryland for all decedents. We analyzed all cases of drug overdose deaths that occurred from 2016 to 2018 (N = 6566) using latent class analysis and regression.
Drug overdose deaths were concentrated in 2 of 24 counties in Maryland (Baltimore City and County). Fentanyl was involved in 71% of all drug overdose deaths, and the majority (76%) of these deaths included multiple substances. Three latent classes emerged (1) fentanyl/heroin/cocaine (64%); (2) fentanyl/alcohol (18%); and (3) prescription drugs including opioids, benzodiazepines and antidepressants (18.0%). The fentanyl/heroin/cocaine class members were significantly younger (<30 years), female and White compared to the fentanyl/alcohol class, but more male and non-White than the prescription drugs class (all P < 0.
