Background: According to past studies, recovery and survival following severe vascular events such as acute myocardial infarction and stroke are negatively impacted by vitamin D deficiency. However, the national estimate on disability-related burden is unclear. We intend to evaluate the prevalence and outcomes of vitamin D deficiency (VDD) among patients with cardiovascular disease (CVD) and cerebrovascular disorder (CeVD). Methods: We performed a cross-sectional study on the Nationwide Inpatient Sample data (2016&ndash, 2017) of adult (&ge, 18 years) hospitalizations. We identified patients with a secondary diagnosis of VDD and a primary diagnosis of CVD and CeVD using the 9th revision of the International Classification of Diseases, clinical modification code (ICD-10-CM) codes. A univariate and mixed-effect multivariable survey logistic regression analysis was performed to evaluate the prevalence, disability, and discharge disposition of patients with CVD and CeVD in the presence of VDD. Results: Among 58,259,589 USA hospitalizations, 3.44%, 2.15%, 0.06%, 1.28%, 11.49%, 1.71%, 0.38%, 0.23%, and 0.08% had primary admission of IHD, acute MI, angina, AFib, CHF, AIS, TIA, ICeH, and SAH, respectively and 1.82% had VDD. The prevalence of hospitalizations due to CHF (14.66% vs. 11.43%), AIS (1.87% vs. 1.71%), and TIA (0.4% vs. 0.38%) was higher among VDD patients as compared with non-VDD patients (p &lt, 0.0001). In a regression analysis, as compare with non-VDD patients, the VDD patients were associated with higher odds of discharge to non-home facilities with an admission diagnosis of CHF (aOR 1.08, 95% CI 1.07&ndash, 1.09), IHD (aOR 1.24, 95% CI 1.21&ndash, 1.28), acute MI (aOR 1.23, 95% CI 1.19&ndash, 1.28), AFib (aOR 1.21, 95% CI 1.16&ndash, 1.27), and TIA (aOR 1.19, 95% CI 1.11&ndash, 1.28). VDD was associated with higher odds of severe or extreme disability among patients hospitalized with AIS (aOR 1.1, 95% CI 1.06&ndash, 1.14), ICeH (aOR 1.22, 95% CI 1.08&ndash, 1.38), TIA (aOR 1.36, 95% CI 1.25&ndash, 1.47), IHD (aOR 1.37, 95% CI 1.33&ndash, 1.41), acute MI (aOR 1.44, 95% CI 1.38&ndash, 1.49), AFib (aOR 1.10, 95% CI 1.06&ndash, 1.15), and CHF (aOR 1.03, 95% CI 1.02&ndash, 1.05) as compared with non-VDD. Conclusions: CVD and CeVD in the presence of VDD increase the disability and discharge to non-home facilities among USA hospitalizations. Future studies should be planned to evaluate the effect of VDD replacement for improving outcomes.

Background ALRN-6924 is a stabilized, cell-permeating alpha-helical peptide that mimics the p53 tumor suppressor protein to disrupt p53’s interactions with its endogenous inhibitors, MDM2 and MDMX. ALRN-6924 has been evaluated in > 175 cancer patients and demonstrated single-agent activity and a well-tolerated single-agent safety profile. MDM2 amplification is an oncogenic event found in up to 4% of all cancers. Co-amplification of MDM2 and cyclin-dependent kinase 4 (CDK4), which are co-located on chromosome 12q13, provides the rationale for combined use of the MDM2-inhibitor ALRN-6924 and the CDK4/6 inhibitor palbociclib in this population, and is further supported by enhanced combination activity in preclinical models. Methods This trial is designed to enroll 25 patients with solid tumors harboring wild-type p53 and MDM2 amplification or MDM2/CDK4 co-amplifications. Patients have exhausted or are not eligible for other treatment options. ALRN-6924 is given at a dose of 3.1 mg/kg as IV infusion on Days 1, 8 and 15, and palbociclib is given as an oral dose of 100 mg/day on Days 1-21 of every 28-day treatment cycle. The first nine patients enrolled were evaluated for safety and tolerability after completion of one treatment cycle (safety lead-in). Anti-tumor activity is evaluated with imaging every 8 weeks. Results Patient enrollment started in December 2018. As of April 30, 12 patients were enrolled; tumor types include liposarcoma (N = 10), osteosarcoma and glioblastoma (1 of each); 11/12 patients had tumors that were MDM2 and CDK4 co-amplified. The combination was generally well tolerated with transient, self-resolving Grade 3 and 4 neutropenia (N = 7) emerging as the principal but not dose limiting toxicity. Other Grade 3 and 4 adverse events include thrombocytopenia, leukopenia, increased ALT, pulmonary embolism, and fall. An interim analysis of activity and safety (N = 15 patients with ≥2 post baseline CT scans) is scheduled for early September 2019 and the results will be presented. Conclusions The combination of ALRN-6924 and palbociclib at pharmacologically relevant doses is feasible and generally well tolerated. Clinical trial identification NCT02909972.

Nearly eighty substituted thiocarbanilides–viz., p -(2-thiazolyl)-, p -(4-thiazolyl)- and p -(5-thiazolyl)- p -alkoxy-thiocarbanilides, and p - p ′-bis(4-thiazolyl)-thiocarbanilides, along with a few thiazolyl thiocarbanilides having halogens on the phenyl ring containing the p ′-alkoxy group, have been synthesized and studied for in vitro antitubercular activity. Also described are over 40 new substituted thiazoles prepared as intermediates. p -(4-Thiazolyl)- p ′- alkoxy-thiocarbanilides in general showed the maximum in vitro tuberculostatic activity in the present study. p -(2,5-Dimethyl-4-thiazolyl)- p ′- n -propoxythiocarbanilide had the same in vitro tuberculostatic activity as isonicotinic acid hydrazide ( INH ) (0.04 mcg./ml.) but did not produce tuberculostatic serum concentration at the same oral dose level as INH .
