Potentially clinically relevant DDIs and possible HDIs were frequently detected in this prospective study. A multidisciplinary approach is required to identify and avoid potentially harmful combinations with anticancer therapy.

PurposeNon-classical actions of vitamin D as a cytokine are related to the immunopathology of asthma. Few studies have examined vitamin D levels and asthma severity in adults. The aim of this research was to assess the relationship between vitamin D levels, atopy markers, pulmonary function, and asthma severity.MethodsWe analyzed 25-hydroxyvitamin D levels in serum collected from 121 asthmatic adults from Costa Rica to investigate the association between vitamin D levels (categorized as sufficient, ≥30 ng/mL, or insufficient, <30 ng/mL), allergic rhinitis, total IgE and peripheral blood eosinophils (as markers of atopy), asthma severity, baseline forced expiratory volume in 1 second (FEV1), and forced vital capacity (FVC). Univariate and multivariate analyses were performed to assess these relationships.ResultsWhen the population was stratified by vitamin D status, 91% of asthmatic patients with vitamin D levels below 20 ng/mL (n=36) and 74% of patients with vitamin D levels between 20 and 30 ng/mL (n=73) had severe asthma versus 50% of those with vitamin D sufficiency (n=12; P=0.02). Vitamin D insufficiency was associated with a higher risk of severe asthma (odds ratio [OR], 5.04; 95% Confidence interval [CI], 1.23-20.72; P=0.02). High vitamin D levels were associated with a lower risk of hospitalization or emergency department visit during the last year (OR, 0.90; 95% CI, 0.84-0.98; P=0.04). Although there appeared to be a direct relationship between vitamin D levels and FEV1 (regression coefficient=0.48; r2=0.03), it did not reach statistical significance (P=0.07).ConclusionsOur findings suggest that vitamin D insufficiency is common among our cohort of asthmatic adults. Lower vitamin D levels are associated with asthma severity.

The addition of CDK 4/6 inhibitors (either abemaciclib, palbociclib, or ribociclib) to an AI (anastrozole or letrozole) significantly improved PFS, overall response rate, and clinical benefit rate in comparison with a nonsteroidal AI alone.

A NLR greater than 3 and a PLR greater than 250 were associated with worse OS and DFS in Hispanic patients with breast cancer.

BackgroundTo compare the efficacy and toxicity of anti-programmed cell death receptor 1 (PD-1) and anti-programmed cell death ligand 1 (PD-L1) versus docetaxel in previously treated patients with advanced non-small cell lung cancer (NSCLC).Materials and methodsPhase III randomised clinical trials (RCTs) were identified after systematic review of databases and conference proceedings. A random-effect model was used to determine the pooled HR for overall survival (OS), progression-free survival (PFS) and duration of response. The pooled OR for overall response and treatment-related side effects were calculated using the inverse-variance method. Heterogeneity was measured using the τ2 and I2 statistics.ResultsAfter the systematic review, we included four phase III RCTs (n=2737) in this meta-analysis. The use of anti-PD-1/anti-PD-L1 agents (atezolizumab, nivolumab and pembrolizumab) was associated with better OS in comparison with docetaxel alone (HR: 0.69; 95% CI 0.63 to 0.75; p<0.00001). Similarly, the PFS and duration of response was significantly longer for patients receiving immunotherapy (HR: 0.85; 95% CI 0.75 to 0.96; p=0.007 and HR:0.32; 95% CI 0.24 to 0.43; p<0.00001, respectively) versus single agent chemotherapy. The overall response rate was also higher for patients who received any anti-PD-1/anti-PD-L1 therapy in comparison with docetaxel (OR: 1.77; 95% CI 1.26 to 2.50; p=0.001). Regarding treatment-related side effects grade 3 or higher, patients who received immunotherapy experienced less events than patients allocated to docetaxel (OR: 0.19; 95% CI 0.12 to 0.30; p<0.00001)ConclusionThe use of anti-PD-1/anti-PD-L1 therapy in patients with progressive advanced NSCLC is significantly better than the use of docetaxel in terms of OS, PFS, duration of response and overall response rate.

Thromboembolic disease is a major leading cause of mortality and morbidity in industrialized countries. Currently, the management of these patients is challenging due to the availability of new drugs with proven efficacy and security compared to traditional oral vitamin K antagonists. These compounds are characterized by a predictable pharmacokinetic profile for which blood monitoring is not routinely needed. Nevertheless, some data have suggested inter-patient variability in the anticoagulant effect of these drugs, raising concerns about their effectiveness and safety. Although mass-spectrometry is the gold standard to determine drug plasma concentrations, this method is not widely available in every-day practice and some coagulation assays are commonly used to determine the anticoagulant effect of these drugs. The present review aims to summarize the current knowledge regarding the clinical question of how and when to monitor patients with new anticoagulant oral agents.
