In humans, practically all movements are learnt and performed in a constant gravitational field. Yet, studies on arm movements and object manipulation in parabolic flight have highlighted very fast sensorimotor adaptations to altered gravity environments. Here, we wondered if the motor adjustments observed in those altered gravity environments could also be observed on Earth in a situation where the body is upside-down. To address this question, we asked participants to perform rhythmic arm movements in two different body postures (right-side-up and upside-down) while holding an object in precision grip. Analyses of grip-load force coordination and of movement kinematics revealed distinct adaptation patterns between grip and arm control. Grip force and load force were tightly synchronized from the first movements performed in upside-down posture, reflecting a malleable allocentric grip control. In contrast, velocity profiles showed a more progressive adaptation to the upside-down posture and reflected an egocentric planning of arm kinematics. In addition to suggesting distinct mechanisms between grip dynamics and arm kinematics for adaptation to novel contexts, these results also suggest the existence of general mechanisms underlying gravity-dependent motor adaptation that can be used for fast sensorimotor coordination across different postures on Earth and, incidentally, across different gravitational conditions in parabolic flights, in human centrifuges, or in Space.NEW & NOTEWORTHY During rhythmic arm movements performed in an upside-down posture, grip control adapted very quickly, but kinematics adaptation was more progressive. Our results suggest that grip control and movement kinematics planning might operate in different reference frames. Moreover, by comparing our results with previous results from parabolic flight studies, we propose that a common mechanism underlies adaptation to unfamiliar body postures and adaptation to altered gravity.Purpose The merits of collaboration between teachers and speech-language pathologists have been extensively highlighted in literature on multitiered educational frameworks. Studies also illustrate the link between articulation, phonemic awareness, and, ultimately, reading skills. This article describes the impact of an intervention targeting articulation and phonemic awareness provided collaboratively to preschool children to enhance emergent literacy skills with the long-term goal of preventing later reading difficulties. Method This pilot study involved a bidirectional collaboration between a speech-language pathologist and a teacher by providing articulatory placement strategies to link accurate speech production with early phonemic awareness activities in the context of a private early childhood center. Seventeen children (N = 17) participated in the study, with ages ranging from 55 to 65 months. Results The results indicated significant differences in phonemic segmentation as well as reading phonemically spelled words and nonwords when comparing the baseline to the collaboratively based articulatory placement plus phonemic awareness intervention. Significant differences were also seen when comparing the traditional literacy program to the collaboratively based articulatory placement plus phonemic awareness intervention. Conclusions The results suggest there may be a benefit to using articulatory placement strategies with phonemic awareness activities directly in the preschool classroom in collaboration with teachers. This pilot study adds to the literature by transferring principles demonstrated as effective for individual children in the research laboratory to application with a whole class in an authentic setting.Background There have been few studies evaluating the costs of palliative care (PC) in low- and middle-income countries (LMICs), especially for patients with cancer. Objectives The objective of this study was to identify the sociodemographic and clinical variables that could explain the cost per day of PC for cancer in Brazil. Encorafenib molecular weight Methods This was a retrospective cost analysis of PC at a quaternary cancer center in São Paulo, Brazil, between January 2010 and December 2013. Factors influencing the cost per day were assessed with generalized linear models and generalized linear-mixed models in which the random effect was the site of the cancer. Results The study included 2985 patients. The mean total cost per patient was $12,335 (standard deviation [SD] = 14,602; 95% confidence interval [CI] = 11,803 to 12,851). The mean cost per day per patient was $325.50 (SD = 246.30, 95% CI = 316.60 to 334.30). There were statistically significant differences among cancer sites in terms of the mean cost per day. Multivariate analysis revealed that the drivers of cost per day were Karnofsky performance status, the number of hospital admissions, referral to PC, and place of death. Place of death had the greatest impact on the cost per day; death in a hospital and in hospice care increased the mean cost per day by $1.56 and $1.83, respectively. Conclusion To allocate resources effectively, PC centers in LMICs should emphasize early enrollment of patients at PC outpatient clinics, to avoid hospital readmission, as well as advance planning of the place of death.Background In the last decade, there has been an unprecedented amount of advocacy and attention surrounding the issue of breast density (BD) in relation to mammography screening. It is largely unknown what impact notifying women of their BD has had on clinical practice for PCPs. This systematic review aimed to synthesize evidence from existing studies to understand the impact of BD notification on primary care practitioners' (PCPs) knowledge, attitudes, and practice implications. Methods Empirical studies were identified through relevant database searches (database inception to May 2020). Two authors evaluated the eligibility of studies, extracted and crosschecked data, and assessed the risk of bias. Results were synthesized in a narrative form. Results Six studies of the 232 titles identified and screened were included. All studies were undertaken in the United States, with five conducted postlegislation in their respective states, and one study conducted in states that were both prelegislation and postlegislation.
