There are marked racial/ethnic differences in hip and knee joint replacement care as well as concerns that value-based payments may exacerbate existing racial/ethnic disparities in care.
To examine changes in joint replacement care associated with Medicare’s Comprehensive Care for Joint Replacement (CJR) model among White, Black, and Hispanic patients.
Retrospective cohort study of Medicare claims from 2013 through 2017 among White, Black, and Hispanic patients undergoing joint replacement in 67 treatment (selected for CJR participation) and 103 control metropolitan statistical areas.
The CJR model holds hospitals accountable for spending and quality of joint replacement care during care episodes (index hospitalization through 90 days after discharge).
The primary outcomes were spending, discharge to institutional postacute care, and readmission during care episodes.
Among 688 346 patients, 442 163 (64.2%) were women, and 87 286 (12.7%) were 85 years or older. Under CJR, spending decreased by $439n joint replacement care still persisted even after these changes.The main curative treatment modality for esophageal cancer is resection. this website Patients initially deemed suitable for resection may become unsuitable, most commonly due to signs of generalized disease or having become unfit for surgery. The aim was to assess risk factors for abandoning esophagectomy and its impact on survival. All patients diagnosed with an esophageal or gastroesophageal junction cancer in the Swedish National Register for Esophageal and Gastric Cancer from 2006-2016 were included and risk factors associated with becoming ineligible for resection were analyzed in multivariable logistic regression analysis. Overall survival was explored by multivariable Cox regression models. Among 1,792 patients planned for resection, 189 (11%) became unsuitable for resection before surgery and 114 (6%) had exploratory surgery without resection. Intermediate and high educational levels were associated with an increased probability of resection (odds ratio (OR) 1.46, 95% CI 1.05-2.05, OR 1.92, 95% CI 1.28-2.87, respectively) as was marital status (married OR 1.37, 95% CI 1.01-1.85). Clinically advanced disease (cT4 OR 0.38, 95% CI 0.16-0.87; cN3 OR 0.27, 95% CI 0.09-0.81) and neoadjuvant treatment were associated with a decreased probability of resection (OR 0.62, 95% CI 0.46-0.88). Five-year survival for non-resected patients was only 4.5% although neoadjuvant treatment was associated with improved survival (HR 0.75, 95% CI 0.56-0.99). Non-resected patients with squamous cell carcinoma had comparatively reduced survival (HR 1.64, 95% CI 1.10-2.43). High socioeconomic status was associated with an increased probability of completing the plan to resect whereas clinically advanced disease and neoadjuvant treatment were independent factors associated with increased risk of abandoning resectional intent.
Dolutegravir is associated with more weight gain than efavirenz. Loss-of-function polymorphisms in CYP2B6 result in higher efavirenz concentrations, which we hypothesized would impair weight gain among people living with human immunodeficiency virus (HIV; PLWH) starting efavirenz-based antiretroviral therapy (ART).
We studied ART-naive participants from the ADVANCE study randomized to the efavirenz /emtricitabine/tenofovir disoproxil fumarate (TDF) and dolutegravir/emtricitabine/TDF arms. We compared changes in weight and regional fat on DXA from baseline to week 48 between CYP2B6 metabolizer genotypes in the efavirenz arm, and with the dolutegravir arm.
There were 342 participants in the dolutegravir arm and 168 in the efavirenz arm who consented to genotyping. Baseline characteristics were similar. Weight gain was greater in women than men. In the efavirenz arm CYP2B6 metaboliser genotype was associated with weight gain (P = .009), with extensive metabolizers gaining the most weight, and with changes among CYP2B6 slow or intermediate metabolizers could explain the increased weight gain on dolutegravir compared with efavirenz observed in ADVANCE and other studies.The nuclear Cap-Binding Complex (CBC), consisting of Nuclear Cap-Binding Protein 1 (NCBP1) and 2 (NCBP2), associates with the nascent 5’cap of RNA polymerase II transcripts and impacts RNA fate decisions. Recently, the C17orf85 protein, also called NCBP3, was suggested to form an alternative CBC by replacing NCBP2. However, applying protein-protein interaction screening of NCBP1, 2 and 3, we find that the interaction profile of NCBP3 is distinct. Whereas NCBP1 and 2 identify known CBC interactors, NCBP3 primarily interacts with components of the Exon Junction Complex (EJC) and the TRanscription and EXport (TREX) complex. NCBP3-EJC association in vitro and in vivo requires EJC core integrity and the in vivo RNA binding profiles of EJC and NCBP3 overlap. We further show that NCBP3 competes with the RNA degradation factor ZC3H18 for binding CBC-bound transcripts, and that NCBP3 positively impacts the nuclear export of polyadenylated RNAs and the expression of large multi-exonic transcripts. Collectively, our results place NCBP3 with the EJC and TREX complexes in supporting mRNA expression.A 5′,7-methylguanosine cap is a quintessential feature of RNA polymerase II-transcribed RNAs, and a textbook aspect of co-transcriptional RNA processing. The cap is bound by the cap-binding complex (CBC), canonically consisting of nuclear cap-binding proteins 1 and 2 (NCBP1/2). Interest in the CBC has recently renewed due to its participation in RNA-fate decisions via interactions with RNA productive factors as well as with adapters of the degradative RNA exosome. A novel cap-binding protein, NCBP3, was recently proposed to form an alternative CBC together with NCBP1, and to interact with the canonical CBC along with the protein SRRT. The theme of post-transcriptional RNA fate, and how it relates to co-transcriptional ribonucleoprotein assembly, is abundant with complicated, ambiguous, and likely incomplete models. In an effort to clarify the compositions of NCBP1-, 2- and 3-related macromolecular assemblies, we have applied an affinity capture-based interactome screen where the experimental design and data processing have been modified to quantitatively identify interactome differences between targets under a range of experimental conditions.
