1.Evaluation of radiation safety in 177Lu-PSMA therapy and development of outpatient treatment protocol.
Demir M1, Abuqbeitah M, Uslu-Beşli L, Yıldırım Ö, Yeyin N, Çavdar İ, Vatankulu B, Gündüz H, Kabasakal L. J Radiol Prot. 2016 Apr 18;36(2):269-278. [Epub ahead of print]
The aim of this study is to investigate the outpatient treatment protocol and radiation safety of a new-emerging lutetium-177 (177Lu) prostate specific membrane antigen (PSMA) therapy. This work analyzed the dose rate of 23 patients treated with 7400 MBq 177Lu-PSMA at different distances (0, 0.25, 0.50, 1.0 and 2.0 m) and variable time marks (0, 1, 2, 4, 18, 24, 48 and 120 h) after the termination of infusion. Blood samples were withdrawn from 17 patients within the same group at 3, 10, 20, 40, 60 and 90 min and 2, 3, 24 h after termination of infusion. Seven different patients were asked to collect urine for 24 h and a gamma well counter was used for counting samples. Family members were invited to wear an optically stimulated luminescence dosimeter whenever they were in the proximity of the patients up to 4-5 d. The total dose of the medical team including the radiopharmacist, physicist, physician, nurse, and nuclear medicine technologist was estimated by an electronic personnel dosimeter.
2.Lurasidone adjunctive with lithium or valproate for bipolar depression: A placebo-controlled trial utilizing prospective and retrospective enrolment cohorts.
Suppes T1, Kroger H2, Pikalov A2, Loebel A3. J Psychiatr Res. 2016 Mar 31;78:86-93. doi: 10.1016/j.jpsychires.2016.03.012. [Epub ahead of print]
In this study, designed to evaluate the efficacy of lurasidone as adjunctive therapy with lithium or valproate, patients with bipolar I depression were randomized to 6 weeks of double-blind treatment with lurasidone (N = 180) or placebo (N = 176), added to background treatment with lithium or valproate. All patients were treated with lithium or valproate for a minimum of 4 weeks prior to screening. This was confirmed either by prospective treatment after study enrolment (run-in cohort), or retrospectively, with blood levels of lithium and valproate at screening (non-run-in cohort). Primary and key secondary endpoints were change from baseline to week 6 on the Montgomery-Åsberg Depression Rating Scale (MADRS) and depression severity score on the Clinical Global Impressions scale for use in bipolar illness (CGI-BP-S), respectively. Treatment with lurasidone was associated with non-significant improvement at week 6 vs. placebo for the MADRS total score (-11.
3.A Click Chemistry-Based Proteomic Approach Reveals that 1,2,4-Trioxolane and Artemisinin Antimalarials Share a Common Protein Alkylation Prof
Ismail HM1, Barton VE2, Panchana M1, Charoensutthivarakul S2, Biagini GA1, Ward SA1, O'Neill PM3. Angew Chem Int Ed Engl. 2016 Apr 18. doi: 10.1002/anie.201512062. [Epub ahead of print]
In spite of the recent increase in endoperoxide antimalarials under development, it remains unclear if all these chemotypes share a common mechanism of action. This is important since it will influence cross-resistance risks between the different classes. Here we investigate this proposition using novel clickable 1,2,4-trioxolane activity based protein-profiling probes (ABPPs). ABPPs with potent antimalarial activity were able to alkylate protein target(s) within the asexual erythrocytic stage of Plasmodium falciparum (3D7). Importantly, comparison of the alkylation fingerprint with that generated from an artemisinin ABPP equivalent confirms a highly conserved alkylation profile, with both endoperoxide classes targeting proteins in the glycolytic, hemoglobin degradation, antioxidant defence, protein synthesis and protein stress pathways, essential biological processes for plasmodial survival. The alkylation signatures of the two chemotypes show significant overlap (ca.
4.What is the Profile of Individuals Joining the KNEEguru Online Health Community? A Cross-Sectional Mixed-Methods Study.
Bright P1, Hambly K, Tamakloe S. J Med Internet Res. 2016 Apr 18;18(4):e84. doi: 10.2196/jmir.5374.
BACKGROUND: The use of the Internet for seekers of health-related information provides convenience and accessibility to diverse sources (of variable quality) for many medical conditions. There is a suggestion that patients may find empowerment by engaging with Internet health care strategies and communities. The profile of consumers of online health information on knee pain has not been explored.
