Twin accelerators and treating on public holidays are effective measures minimizing RT breaks. For HNC, patient compliance is mostly limited by RT side-effects. Efforts to maintain RT biological effective dose in HNC must be always undertaken.

Nowadays, the optimization in digital mammography is one of the most important challenges in diagnostic radiology. The new digital technology has introduced additional elements to be considered in this scenario. A major goal of mammography is related to the detection of structures on the order of micrometers (μm) and the need to distinguish the different types of tissues, with very close density values. The diagnosis in mammography faces the difficulty that the breast tissues and pathological findings have very close linear attenuation coefficients within the energy range used in mammography. The aim of this study was to develop a methodology for optimizing exposure parameters of digital mammography based on a new Figure of Merit: FOM ≡ (IQF)/AGD, considering the image quality and dose. The study was conducted using the digital mammography Senographe DS/GE, and CDMAM and TORMAM phantoms. The characterization of clinical practice, carried out in the mammography system under study, was performed considering different breast thicknesses, the technical parameters of exposure, and processing options of images used by the equipment's automatic exposure system. The results showed a difference between the values of the optimized parameters and those ones chosen by the automatic system of the mammography unit, specifically for small breast. The optimized exposure parameters showed better results than those obtained by the automatic system of the mammography, for the image quality parameters and its impact on detection of breast structures when analyzed by radiologists.

Objective To examine the effectiveness of the FIFA 11+ in reducing injury in futsal players. Methods Ninety‐one male futsal players from six amateur futsal clubs were recruited and assessed for eligibility, and 71 were randomized to the 11+ group (n = 37, age: 27.0 ± 5.1 years) and a control group (n = 34, age: 26.0 ± 5.1 years). The 11+ program was executed twice a week for 20 weeks, separated by a 10‐week period where both groups executed their regular warm‐up. Data on match, training exposure, and injuries were recorded during the regular season. Results The players sustained a total of 58 injuries during the futsal regular season, with 24 injuries in the 11+ group and 34 injuries in the control group; the overall incidence of injuries per 1000 player‐hours was significantly higher in the control group (11.6 vs 6.5; mean difference (95% CI) −5.1 (−9.1 to −1.1), P = .014). The 11+ group had a significantly lower incidence of acute (11.2 vs 5.7; −5.5 (−9.4 to −1.6), P = .007) and lower limb (8.7 vs 4.4; −4.2 (−8.1 to −0.4), P = .032) injuries per 1000 player‐hours. Players from the control group had a higher number of days injured (20.4 ± 17.3 vs 10.5 ± 9.1, P = .036). Conclusion The FIFA 11+ is an injury prevention program suited for injury reduction in amateur futsal players, as it reduces the incidence of overall, acute, and lower limb injuries during the season.
