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 Blood samples were withdrawn from 17 patients within the same group at 3, 10, 20, 40, 60 and 90 min and 2, 3, 24 h after termination of infusion.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.Health Effects of Alkaline Diet and Water, Reduction of Digestive-tract Bacterial Load, and Earthing.
Mousa HA. Altern Ther Health Med. 2016 Apr;22(S1):24-33.
In the article, the author discusses the issue of chronic, low-grade acidosis that is thought to be brought about primarily by 2 factors: (1) advancing age, with a consequent decline in renal function; and (2) diet. An acid-forming diet can induce low-grade metabolic acidosis, which causes very small decreases in blood pH and plasma bicarbonate (HCO3-) that remain within the range considered to be normal. However, if the duration of the acidosis is prolonged or chronically present, even a low degree of acidosis can become significant. This article reviews supporting evidence in the literature that has shown that consumption of abundant alkaline-forming foods can result in improvement in bone mineral density (BMD) and muscle mass, protection from chronic illnesses, reduced tumor-cell invasion and metastasis, and effective excretion of toxins from the body. In addition, a large number of studies showing the benefits of alkaline water (mineral water) have revealed that people consuming water with a high level of total dissolved solids (TDS) (ie, with a high mineral content) have shown a lower incidence of coronary heart disease (CHD), cardiovascular disease (CVD), and cancer and lower total mortality rates.
3.Uncertainty in Treatment Rankings: Reanalysis of Network Meta-analyses of Randomized Trials.
Trinquart L, Attiche N, Bafeta A, Porcher R, Ravaud P. Ann Intern Med. 2016 Apr 19. doi: 10.7326/M15-2521. [Epub ahead of print]
Background: Ranking of interventions is one of the most appealing elements of network meta-analysis. There is, however, little evidence about the reliability of these rankings.
4.MRI-based IMRT planning for MR-linac: comparison between CT- and MRI-based plans for pancreatic and prostate cancers.
Prior P1, Chen X, Botros M, Paulson ES, Lawton C, Erickson B, Li XA. Phys Med Biol. 2016 Apr 18;61(10):3819-3842. [Epub ahead of print]
The treatment planning in radiation therapy (RT) can be arranged to combine benefits of computed tomography (CT) and magnetic resonance imaging (MRI) together to maintain dose calculation accuracy and improved target delineation. Our aim is study the dosimetric impact of uniform relative electron density assignment on IMRT treatment planning with additional consideration given to the effect of a 1.5 T transverse magnetic field (TMF) in MR-Linac. A series of intensity modulated RT (IMRT) plans were generated for two representative tumor sites, pancreas and prostate, using CT and MRI datasets. Representative CT-based IMRT plans were generated to assess the impact of different electron density (ED) assignment on plan quality using CT without the presence of a 1.5 T TMF. The relative ED (rED) values used were taken from the ICRU report 46. Four types of rED assignment in the organs at risk (OARs), the planning target volumes (PTV) and in the non-specified tissue (NST) were considered.
