Which cancer survivors are at risk for a physically inActive and sedentary lifestyle? Results from pooled accelerometer data of 1447 cancer survivors
International Journal of Behavioral Nutrition and Physical Activity, 2019Co-Authors: M. G. Sweegers, A. D’silva, C. S. Kampshoff, B. M. Lynch, Neil K Aaronson, Mai J M Chinapaw, Johannes Brug, Jeff K Vallance, T. Boyle, Friedel NolletAbstract:BackgroundPhysical activity has beneficial effects on the health of cancer survivors. We aimed to investigate accelerometer-assessed physical activity and sedentary time in cancer survivors, and describe activity Profiles. Additionally, we identify demographic and clinical correlates of physical activity, sedentary time and activity Profiles.MethodsAccelerometer, questionnaire and clinical data from eight studies conducted in four countries (n = 1447) were pooled. We calculated sedentary time and time spent in physical activity at various intensities using Freedson cut-points. We used latent Profile analysis to identify activity Profiles, and multilevel linear regression analyses to identify demographic and clinical variables associated with accelerometer-assessed moderate to vigorous physical activity (MVPA), sedentary time, the highly Active and highly sedentary Profile, adjusting for confounders identified using a directed acyclic graph.ResultsParticipants spent on average 26 min (3%) in MVPA and 568 min (66%) sedentary per day. We identified six activity Profiles. Older participants, smokers and participants with obesity had significantly lower MVPA and higher sedentary time. Furthermore, men had significantly higher MVPA and sedentary time than women and participants who reported less fatigue had higher MVPA time. The highly Active Profile included survivors with high education level and normal body mass index. Haematological cancer survivors were less likely to have a highly Active Profile compared to breast cancer survivors. The highly sedentary Profile included older participants, males, participants who were not married, obese, smokers, and those

potential influence of sea level rise in controlling shoreline position on the french mediterranean coast
Geomorphology, 2009Co-Authors: Cedric Brunel, Francois SabatierAbstract:Abstract We analysed the rates of relative sea-level rise (RSLR) and the variations in shoreline position over more than a century on pocket-beaches in Provence and on open beaches of the Camargue (France). Our objective is to quantify the role of sea-level rise in the shoreline retreat, and evaluate this retreat in terms of future sea-level rise. The methodology did not use the classical Bruun rule but the principle of Active flooding which combines the RSLR with the slope of the beach Profile. This slope is averaged between the shoreline and the upper and lower part of the Active Profile. On the wave-dominated open-beaches of the Camargue, the sea-level rise between 1895 and 1977 yields a theoretical averaged retreat of − 34.8 m along eroding beaches, but this value eventually represents only a small proportion (8%) of the total historical distance of shoreline retreat. On open-beaches exposed to the swell, (Camargue), rising sea level enhances the erosion, which is itself ultimately dependent on the action of the waves (longshore transport, cross-shore processes) and the sedimentary budget. In other words, sea-level rise is not the major cause of coastal erosion and does not represent the most severe risk along this type of shore. Moreover, the cross-shore processes of overwash “assist” the shoreline retreat by compensating for sea-level rise. On the other hand, since sea-level rise is one of the principal factors influencing shoreline retreat, the acceleration in sea-level rise predicted for 2100 will play an important role in the future position of the shoreline on pocket-beaches protected from wave action and with limited back-shore areas (i.e. the beaches of Provence). The width of the beaches is going to decrease significantly with the increasing risk of disappearance of some beaches. Indeed, if we integrate the low rates of long-term retreat, and taking account of the morphology of the back beach, then the pocket-beaches appear to be threatened by disappearance due to sea-level rise. Under these conditions, sea-level rise will have important socio-economic impacts on the pocket-beaches of Provence.

mechanical behavior and failure analysis of prosthetic retaining screws after long term use in vivo part 1 characterization of adhesive wear and structure of retaining screws
Journal of Prosthodontics, 2008Co-Authors: Youssef Al S Jabbari, R A Fournelle, Gerald J Ziebert, Jeffrey M Toth, Anthony M IacopinoAbstract:Purpose: The general aim of this study and those presented in Parts 2–4 of this series was to characterize the structure, properties, wear, and fracture of prosthetic retaining screws in fixed detachable hybrid prostheses after long-term use in vivo. This part of the overall investigation addresses whether there are differences in thread wear between the screws closest to the fulcrum and those that are farthest from the fulcrum in fixed detachable hybrid prostheses. Materials and Methods: The total number of prosthetic retaining screws used in this study was 100 (10 new and 90 used). New screws (controls) from Nobel Biocare (NB) were divided into Group 1 (slotted) and Group 2 (hexed). Ninety used screws (in service 18–120 months) were retrieved from fixed detachable hybrid prostheses in 18 patients (5 screws from each patient, 60 from NB and 30 from Sterngold). The used screws were divided into 18 groups. Additionally, each group was subdivided into A and B categories. Category A contained the middle three prosthetic screws, which were considered the farthest screws from the fulcrum line. Category B contained the most posterior two screws, which were considered the screws closest to the fulcrum line. All 100 screws were subjected to thorough, nondestructive testing. Results: Light and scanning electron microscopic examination of all used screws for each group revealed surface deterioration of the Active Profile of the screw threads consistent with adhesive wear. The observed thread Profile deterioration ranged from mild to severe. The wear was aggressive enough to cause galling, which led to thinning of the threads and, in severe cases, to knife-edges at thread crests. In ten groups, the most anterior three screws exhibited more wear than the most posterior two screws. In addition to thread wear, severe plastic deformation was detected on the bottom part of each screw for three groups, and a long external longitudinal crack was detected in one screw of Group 2. Conclusions: The findings of this study and those presented in Parts 2–4 demonstrate that different retaining screws from the same manufacturer and/or from different manufacturers have different geometrical design, microstructures, major alloy constituents, and microhardness, and that these differences influence their preload and fractured load values. In this part of the overall investigation, the occurrence of galling as a result of wear involving prosthetic retaining screws appears to be an inevitable and unavoidable consequence of long-term use in vivo in fixed detachable hybrid prostheses regardless of the intended/original preload value. The galling rate is greater on the middle three screws compared to the most posterior two screws in fixed detachable hybrid prostheses. The wear pattern is consistent with an adhesive wear mechanism; however, this study does not provide enough data to support a definitive analysis.

Feasibility of anterior screw fixation in children: a tomographic study
European Spine Journal, 2018Co-Authors: Livia Gaspar Fernandes, Alexandre Fogaça Cristante, Raphael Martus Marcon, Tarcísio Eloy Pessoa De Barros Filho, Olavo Biraghi LetaifAbstract:Purpose Morphology measures of the odontoid process in children under 12 years old were carried out to demonstrate the viability of anterior internal fixation in this population once their Active Profile may not be compatible with successful conservative treatment. Methods During a 6-month period, 36 tomographic examinations of the cervical spine region that provided visualization of the odontoid process were selected. Group 1 included children between 6 and 9 years of age, and group 2 contained children from 9 to 12 years of age. There were 23 (63.8%) male patients and 13 (36.2%) female patients. Patients diagnosed with a tumor, an infection, fracture non-union, or congenital malformation were excluded. Exams were ordered as part of a protocol applied to non-specific neck pain and pediatric trauma entries. The following parameters were analyzed: (1) screw attack angle, (2) height of the odontoid process, and (3) minimal transverse diameter of the odontoid process. Results In Groups 1 and 2, the average values of the screw attack angle were 55.9° ± 2.3° and 54.8° ± 4.5°, respectively; the average heights of the odontoid process were 26.58 ± 3.28 and 29.48 ± 3 mm, respectively, and the average minimal transverse diameter of the odontoid process were 6.57 ± 1.08 and 6.23 ± 0.88 mm, respectively. The minimal transverse diameter of the odontoid process was statistically higher in males than that in females, regardless of age ( p = 0.007). Conclusion In both groups, the minimal transverse diameter of the odontoid process allowed for the use of one 3.5–4.5 mm screw for anterior internal fixation.
