Multi-centre technical evaluation of the radiation-induced lymphocyte apoptosis assay as a predictive test for radiotherapy toxicity.

In this study we tested the potential of the assay for standardisation and use in multiple testing laboratories. The assay was standardised and reproducibility determined using samples from healthy volunteers assayed concurrently in three laboratories in Leicester (UK), Mannheim (Germany) and Montpellier (France). RILA assays were performed on samples taken prior to radiotherapy from 1319 cancer patients enrolled in the REQUITE project at multiple centres. The patients were being treated for breast (n = 753), prostate (n = 506) or lung (n = 60) cancer. Inter-laboratory comparisons identified several factors affecting results: storage time, incubation periods and type of foetal calf serum. Following standardisation, there was no significant difference in results between the centres. Significant differences were seen in RILA scores between cancer types (prostate > breast > lung), by smoking status (non-smokers > smokers) and co-morbidity with rheumatoid arthritis (arthritics > non-arthritics). An analysis of acute radiotherapy toxicity showed as expected that RILA assay does not predict most end-points, but unexpectedly did predict acute breast pain. This result may elucidate the mechanism by which the RILA assay predicts late radiotherapy toxicity. The work shows clinical trials involving multiple laboratory measurement of the RILA assay are feasible and the need to account for tumour type and other variables when applying to predictive ...

ABSTRACT OBJECTIVE To evaluate the factors associated with tooth loss in adults from the position and number of teeth lost in the dental arches. METHODS This is a cross-sectional, population-based study with adults participating in the epidemiological survey of oral health of S ão Paulo in 2015. The outcome of the study was tooth loss, assessed by the proposed classification, namely: I) lost up to 12 back teeth; II) lost up to 12 teeth (including front teeth); and III) lost more than 12 teeth. A four-block analysis was conducted, supported by a conceptual theoretical mode l adapted for tooth loss. For the multinomia...

ConclusionA long history of shoulder pain that is not responsive to conservative management in young patients should raise the suspicion of an "OO", and physicians should be encouraged to use early advanced imaging modalities in order to confirm it.

ConclusionGiven the increasing number of such surgeries performed the recognition of acute and chronic complications, and their optimal management is of great importance. Although performing a Roux-en-Y fistulojejunostomy was recommended in the literature, conservative and endoscopic treatment should be considered before.

In this study, we evaluated the effect of auranofin on the radiosensitivity of intestinal epithelial cells. The treatment with a combination of 1 μM auranofin and 5 Gy ionizing radiation showed clear additive effects on caspase 3 cleavage and apoptotic DNA fragmentation in IEC-6 cells, and auranofin administration significantly aggravated the radiation-induced intestinal injury in mice. Auranofin treatment also resulted in the activation of the unfolded protein response and in the inhibition of thioredoxin reductase, which is a key component of the cellular antioxidant system. Pre-treatment with N-acetyl cysteine, a wel...

00:00 to 02.26—Dr. Bihari gives his background and credentials. Dr. Bihari: My medical training started at Harvard Medical School. I graduated in 1957. Then I trained in Internal Medicine at one of the Harvard teaching hospitals in Boston, Beth Israel, and then in Neurology at Massachusetts General in Boston. Then I went to the National Institutes of Health for two years doing brain physiology—brain research. I did another residency training in Psychiatry in New York, at Columbia Presbyterian Medical Center and then, over the following five or six years, I got very involved in working in Drug Addiction.
