Which alpha/beta ratio and half-time of repair are useful for predicting outcomes in prostate cancer?

To calculate the ?/? of prostate adenocarcinoma.From January 1997 to December 2005, 328 patients were treated consecutively with external beam radiotherapy and brachytherapy boost. The patients with at least one of the following adverse prognostic factors were included: PSA>10 ng/ml, Gleason score ?7, T?2B. A total EQD2 of 80 Gy was delivered uniformly within the same timeframe. Prior to August 2002, the patients were treated to low-dose-rate brachytherapy using (192)Ir (n=201), and those treated thereafter received a high-dose-rate brachytherapy boost (n=127). The equivalency of dose was established using the incomplete repair model, with generally accepted ?/? ratio of 3 Gy, and half-time for repair of sublethal damage (HTR) of 1.5h.In a Cox proportional hazards model, the two groups displayed no difference (HR: 0.99, 95% CI: 0.87-1.1, p=0.98) in biochemical control. Analyzing using the linear quadratic model, the data fit well an ?/? ratio of 3.41 Gy (95% CI: 2.56-4.26) and the recently published HTR of 1.9 h (95% CI: 1.4-2.4), but also an ?/? of 5.87 Gy (95% CI: 4.67-7.07) and the more widely established HTR of 1.5 h.Unlike the previously published data, calculation of the ?/? ratio from consecutive patients and using a uniform treatment duration points to higher values than 2.5 Gy

The Antarctic Planet Interferometer

The Antarctic Planet Interferometer is an instrument concept designed to detect and characterize extrasolar planets by exploiting the unique potential of the best accessible site on earth for thermal infrared interferometry. High-precision interferometric techniques under development for extrasolar planet detection and characterization (differential phase, nulling and astrometry) all benefit substantially from the slow, low-altitude turbulence, low water vapor content, and low temperature found on the Antarctic plateau. At the best of these locations, such as the Concordia base being developed at Dome C, an interferometer with two-meter diameter class apertures has the potential to deliver unique science for a variety of topics, including extrasolar planets, active galactic nuclei, young stellar objects, and protoplanetary disks

2019 ESC Guidelines for the diagnosis and management of acute pulmonary embolism developed in collaboration with the European Respiratory Society (ERS).

Guidelines summarize and evaluate available evidence with the aim of assisting health professionals in proposing the best management strategies for an individual patient with a given condition. Guidelines and their recommendations should facilitate decision making of health professionals in their daily practice. However, the final decisions concerning an individual patient must be made by the responsible health professional(s) in consultation with the patient and caregiver as appropriate
