A Comprehensive Examination of the Immediate Recovery of Children Following Tonsillectomy and Adenoidectomy
Objectives Using multiple well-validated measures and a large sample size, the goal of this paper was to describe the immediate clinical and behavioral recovery of children following tonsillectomy with or without an adenoidectomy (T&A) during the first two weeks following surgery. Study design Observational, longitudinal study. Setting Four major pediatric hospitals in the U.S. consisting of Children\u27s Hospital of Orange County, Children\u27s Hospital of Los Angeles, Lucile Packard Children\u27s Hospital, and Children\u27s Hospital Colorado. Subjects and Methods: Participants included 827 patients between 2 and 15 years of age who underwent tonsillectomy with or without adenoidectomy surgery. Baseline and demographic information were gathered prior to surgery, and measures of clinical, behavioral, and physical recovery were recorded immediately following and up through two weeks after surgery. Results Pain following T&A was clinically significant through the first post-operative week and nearly resolved by the end of the second week. Negative behavioral changes were highly prevalent after surgery (75.6% of children at Day 0) through the first week (63.9% at Week 1), and over 20% of children continued to evidence new onset negative behavioral changes at two weeks post-operatively. Children were rated as experiencing significant functional impairment in the immediate three days following surgery and most children returned to baseline functioning by the end of the second week. Conclusions Results of this study suggest that children show immediate impairment in functioning and experience clinically significant pain throughout the first week following T&A, and new onset maladaptive behavioral changes persisting even up to the two-week assessment period
American Society for Bone and Mineral Research-Orthopaedic Research Society Joint Task Force Report on Cell-Based Therapies.
Cell-based therapies, defined here as the delivery of cells in vivo to treat disease, have recently gained increasing public attention as a potentially promising approach to restore structure and function to musculoskeletal tissues. Although cell-based therapy has the potential to improve the treatment of disorders of the musculoskeletal system, there is also the possibility of misuse and misrepresentation of the efficacy of such treatments. The medical literature contains anecdotal reports and research studies, along with web-based marketing and patient testimonials supporting cell-based therapy. Both the American Society for Bone and Mineral Research (ASBMR) and the Orthopaedic Research Society (ORS) are committed to ensuring that the potential of cell-based therapies is realized through rigorous, reproducible, and clinically meaningful scientific discovery. The two organizations convened a multidisciplinary and international Task Force composed of physicians, surgeons, and scientists who are recognized experts in the development and use of cell-based therapies. The Task Force was charged with defining the state-of-the art in cell-based therapies and identifying the gaps in knowledge and methodologies that should guide the research agenda. The efforts of this Task Force are designed to provide researchers and clinicians with a better understanding of the current state of the science and research needed to advance the study and use of cell-based therapies for skeletal tissues. The design and implementation of rigorous, thorough protocols will be critical to leveraging these innovative treatments and optimizing clinical and functional patient outcomes. In addition to providing specific recommendations and ethical considerations for preclinical and clinical investigations, this report concludes with an outline to address knowledge gaps in how to determine the cell autonomous and nonautonomous effects of a donor population used for bone regeneration. © 2019 American Society for Bone and Mineral Research

Strengthening the reporting of genetic risk prediction studies (GRIPS): explanation and elaboration
The rapid and continuing progress in gene discovery for complex diseases is fuelling interest in the potential application of genetic risk models for clinical and public health practice. The number of studies assessing the predictive ability is steadily increasing, but they vary widely in completeness of reporting and apparent quality. Transparent reporting of the strengths and weaknesses of these studies is important to facilitate the accumulation of evidence on genetic risk prediction. A multidisciplinary workshop sponsored by the Human Genome Epidemiology Network developed a checklist of 25 items recommended for strengthening the reporting of Genetic RIsk Prediction Studies (GRIPS), building on the principles established by prior reporting guidelines. These recommendations aim to enhance the transparency, quality and completeness of study reporting, and thereby to improve the synthesis and application of information from multiple studies that might differ in design, conduct or analysis
Bioavailability of Macro and Micronutrients Across Global Topsoils: Main Drivers and Global Change Impacts
Understanding the chemical composition of our planet\u27s crust was one of the biggest questions of the 20th century. More than 100 years later, we are still far from understanding the global patterns in the bioavailability and spatial coupling of elements in topsoils worldwide, despite their importance for the productivity and functioning of terrestrial ecosystems. Here, we measured the bioavailability and coupling of thirteen macro- and micronutrients and phytotoxic elements in topsoils (3â8 cm) from a range of terrestrial ecosystems across all continents (âŒ10,000 observations) and in response to global change manipulations (âŒ5,000 observations). For this, we incubated between 1 and 4 pairs of anionic and cationic exchange membranes per site for a mean period of 53 days. The most bioavailable elements (Ca, Mg, and K) were also amongst the most abundant in the crust. Patterns of bioavailability were biome-dependent and controlled by soil properties such as pH, organic matter content and texture, plant cover, and climate. However, global change simulations resulted in important alterations in the bioavailability of elements. Elements were highly coupled, and coupling was predictable by the atomic properties of elements, particularly mass, mass to charge ratio, and second ionization energy. Deviations from the predictable coupling-atomic mass relationship were attributed to global change and agriculture. Our work illustrates the tight links between the bioavailability and coupling of topsoil elements and environmental context, human activities, and atomic properties of elements, thus deeply enhancing our integrated understanding of the biogeochemical connections that underlie the productivity and functioning of terrestrial ecosystems in a changing world

Nutrition and the ageing brain: moving towards clinical applications
The global increases in life expectancy and population have resulted in a growing ageing population and with it a growing number of people living with age-related neurodegenerative conditions and dementia, shifting focus towards methods of prevention, with lifestyle approaches such as nutrition representing a promising avenue for further development. This overview summarises the main themes discussed during the 3 Symposium on "Nutrition for the Ageing Brain: Moving Towards Clinical Applications" held in Madrid in August 2018, enlarged with the current state of knowledge on how nutrition influences healthy ageing and gives recommendations regarding how the critical field of nutrition and neurodegeneration research should move forward into the future. Specific nutrients are discussed as well as the impact of multi-nutrient and whole diet approaches, showing particular promise to combatting the growing burden of age-related cognitive decline. The emergence of new avenues for exploring the role of diet in healthy ageing, such as the impact of the gut microbiome and development of new techniques (imaging measures of brain metabolism, metabolomics, biomarkers) are enabling researchers to approach finding answers to these questions. But the translation of these findings into clinical and public health contexts remains an obstacle due to significant shortcomings in nutrition research or pressure on the scientific community to communicate recommendations to the general public in a convincing and accessible way. Some promising programs exist but further investigation to improve our understanding of the mechanisms by which nutrition can improve brain health across the human lifespan is still required

A model of anti-modernism : an introduction to Nietzscheâs rationalistic rejection of liberal democracy
textThe thought of Friedrich Nietzsche is often taught, but seldom sufficiently understood, and thus what ought to be most challenging to us about Nietzsche â that is, the rationalistic basis of his rejection of liberal democracy â is not squarely confronted. I propose to lay the ground for such a confrontation.Governmen
