  Whether concomitant administration of anticancer agents influences the efficacy and safety of oral anticoagulants in patients treated for cancer-associated venous thromboembolism (VTE) is undefined. The pharmacological interaction between anticancer agents and direct oral anticoagulants is perceived as a concern.
 
  We evaluated the effects of concomitant administration of anticancer agents on recurrent VTE, major bleeding and death in patients with cancer-associated VTE randomised to receive apixaban or dalteparin in the Caravaggio study.
 
  Anticancer agents were concomitantly given to 336 patients (58.3%) treated with apixaban and to 332 patients (57.3%) treated with dalteparin. In patients treated with apixaban, recurrent VTE occurred in 20 (6.0%) and 12 (5.0%) among patients treated or not treated with anticancer agents, respectively (hazard ratio [HR]=1.14; 0.55-2.38); major bleeding occurred in 12 (3.6%) and 10 (4.2%) patients, respectively (HR=0.79; 0.34-1.82), and death occurred in 74 (22.0%) and 61 nts treated with apixaban or dalteparin for cancer-associated VTE.
  In view of the potential gravity of severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) infection for patients with cancer, epidemiological data are vital to assess virus circulation among patients and staff of cancer centres. We performed a prospective study to investigate seroprevalence of SARS-CoV-2 antibodies among staff and patients with cancer at a large cancer centre, at the end of the period of first national lockdown in Franceand to determine factors associated with the risk of SARS-CoV-2 infection.
 
  After the first lockdown, all medical and non-medical staff, as well as all patients attending the medical oncology department were invited to undergo serological testing for SARS-CoV-2 between 11 May and 30 June 2020. All participants were also invited to complete a questionnaire collecting data about their living and working conditions, and for patients, medical management during lockdown.
 
  A total of 1,674 subjects (663 staff members, 1011 patients) were included. Seroprevalence was low ie, personal protection, and social distancing measures were implemented.Several global efforts are underway to develop COVID-19 vaccines, and interim analyses from phase 3 clinical testing have been announced by nine organisations Pfizer, the Gamaleya Research Institute of Epidemiology and Microbiology, Moderna, AstraZeneca, Sinopharm Group, Sinovac Biotech, Johnson & Johnson, Novavax, and CanSino Biologics. The US programme known as Operation Warp Speed provided US$18 billion in funding for development of vaccines that were intended for US populations. Depending on safety and efficacy, vaccines can become available through mechanisms for emergency use, expanded access with informed consent, or full licensure. An important question is how will these Operation Warp Speed vaccines be used for COVID-19 prevention in global health settings? We address some key questions that arise in the transition from US to global vaccine prevention efforts and from ethical and logistical issues to those that are relevant to global vaccine security, justice, equity, and diplomacy.
  Furmonertinib (AST2818) is a third-generation epidermal growth factor receptor (EGFR) tyrosine kinase inhibitor (TKI) targeting both sensitising EGFR and EGFR Thr790Met (T790M) mutations. This study aimed to assess the efficacy and safety of furmonertinib in patients with EGFR T790M mutated advanced non-small-cell lung cancer (NSCLC).
 
  This study was a single-arm, open-label, phase 2b study at 46 hospitals across mainland China.  https://www.selleckchem.com/products/amg-232.html  Patients with locally advanced or metastatic NSCLC with centrally confirmed EGFR T790M mutations in tumour tissue who progressed after first or second generation EGFR TKIs or with primary EGFR T790M mutations received furmonertinib 80 mg orally once daily. The primary endpoint was objective response rate. Efficacy was assessed by blinded independent central review as per the Response Evaluation Criteria in Solid Tumors (version 1.1) in all patients who had measurable disease at baseline and received at least one dose of furmonertinib. Safety was assessed as per the Common Terminoloemia, and pericardial effusion (three each; 1%). Treatment-related diarrhoea was reported in ten (5%) patients and rashes were reported in 16 (7%) patients, all grade 1-2. Serious adverse events were reported in 52 (24%) patients, of which 12 (5%) were possibly treatment-related as evaluated by the investigator.
 
  Furmonertinib has promising efficacy and an acceptable safety profile for the treatment of patients with EGFR T790M mutated NSCLC. Furmonertinib is expected to become a new treatment option after first or second generation EGFR TKIs in the Chinese population.

However, their use has been limited in recent years due to their potential induction of nephrotoxicity. Here we investigate the possibility of reversing nephrotoxicity caused by gentamicin in rat models by using ethanolic crude extract of the medicinal plant Jatropha Mollissima. Nephrotoxic male Wistar rats was obtained by gentamicin antibiotic, which then treated with two doses of J. mollissima crude extract for 3 weeks with monitoring their parameter in weekly base. Our results indicate that J. mollissima crude extract at both doses has strong protection ability against gentamicin nephrotoxicity, most of tested parameters backed to normal values after few days from the administration of the crude extract, which could be due to the antagonized the biochemical action of gentamicin on the proximal tubules of the kidney. The results of histopathologic analysis showed observable improvement in J.
