Effect of level of sedation on outcomes in critically ill adult patients : a systematic review of clinical trials with meta-analysis and trial sequential analysis

Background: Sedation is routinely administered to critically ill patients to alleviate anxiety, discomfort, and patient-ventilator asynchrony. However, it must be balanced against risks such as delirium and prolonged intensive care stays. This study aimed to investigate the effects of different levels of sedation in critically ill adults. Methods: Systematic review with meta-analysis and trial seq

A knowledge integration framework for robotics

This paper describes a knowledge integration framework for robotics, whose goal is to represent, store, adapt, and distribute knowledge across engineering platforms. The architecture abstracts the components as data sources, where data are available in the AutomationML data exchange format. AutomationML is an on-going standard initiative that aims at unifying data representation and APIs used by e

On the discovery of new elements (IUPAC/IUPAP Report) : Report of the 2017 Joint Working Group of IUPAC and IUPAP

Almost thirty years ago the criteria that are currently used to verify claims for the discovery of a new element were set down by the comprehensive work of a Transfermium Working Group, TWG, jointly established by IUPAC and IUPAP. The recent completion of the naming of the 118 elements in the first seven periods of the Periodic Table of the Elements was considered as an opportunity for a review of

Increased intracranial pressure in severe traumatic axonal injury patients - A retrospective single-center study

Introduction: Traumatic axonal injury (TAI), often caused by rapid rotational forces and high-energy accidents, is common in severe traumatic brain injury (sTBI). The intracranial pressure (ICP) dynamics are often unpredictable, and the need for ICP monitoring remains debated. Research question: What is the incidence of ICP elevation in patients with TAI, and how often is escalated ICP-lowering tr

Tracking the Reinstatement of Semantic and Emotional Information during Episodic Memory Retrieval

Retrieving episodic memories often involves reconstructing both their semantic content and the emotional context in which they occurred. However, the neural mechanisms that differentiate these forms of reinstatement remain poorly understood. This event-related potential (ERP) study examines how semantic category and emotional valence are reinstated during memory retrieval.Seventy participants enco

Extremely Large Telescopes Optical Design and Wavefront Correction

Popular Abstract in Swedish Extremt stora teleskop, optisk konstruktion och vågfrontskorrektion 1 Nya resultat inom astronomin För astronomin har senare årtionden varit ytterst händelserika. Ett flertal fascinerande upptäckter har förädlat vår kunskap om universum och dess stjärnor, planeter, galaxer och storskaliga strukturer. Vi har fått bättre grepp om universums ålder, struktur och utvecklinAn overview of the state of art within optical design of large astronomical telescopes is given. Recent advances within the field are presented. The importance of new computer-controlled mirror-polishing methods is emphasized. Some important aspects of atmospheric optics are presented together with current compensation methods using adaptive optics, with or without laser guide stars. An overview o

The Employment Contract Revisited.

This article considers recent legal developments on undocumented migrant workers, finds the acceptance of international legal standards unsatisfactory and argues that the private law rights derived from the "semi-legal" employment contract between the employer and the undocumented migrant worker generates a solid base for significant legal claims. It further monitors the promotion of the position

Outcome of patients with acquired aplastic anemia given first line bone marrow transplantation or immunosuppressive treatment in the last decade: a report from the European Group for Blood and Marrow Transplantation (EBMT)

BACKGROUND AND OBJECTIVES: The treatment of acquired aplastic anemia (AA) is based on allogeneic bone marrow transplantation (BMT) and immunosuppressive therapy. The aim of this study was to assess the outcome of children and adults with AA treated in the last decade, and to determine whether results have improved in two sequential time periods,1991-1996 and 1997-2002. DESIGN AND METHODS: Two-thou

Optimal Virtual Array Length Under Position Imperfections

This article contains a study of how spatial errors and receiver imperfections affect the angle of arrival estimation accuracy for virtual antenna arrays. A virtual antenna array consists of one receiver element whose location is tracked as the element is moved and in this work, linear arrays are studied. If the location of the receiver is tracked using an inertial measurement unit, an interesting

SOX9 is a major negative regulator of cartilage vascularization, bone marrow formation and endochondral ossification

SOX9 is a transcription factor of the SRY family that regulates sex determination, cartilage development and numerous other developmental events. In the foetal growth plate, Sox9 is highly expressed in chondrocytes of the proliferating and prehypertrophic zone but declines abruptly in the hypertrophic zone, suggesting that Sox9 downregulation in hypertrophic chondrocytes might be a necessary step

Leukocyte telomere length predicts SSRI response in major depressive disorder : A preliminary report

Short leukocyte telomere length (LTL) may be associated with several psychiatric disorders, including major depressive disorder (MDD). Short LTL has previously been associated with poor response to psychiatric medications in bipolar disorder and schizophrenia, but no studies have prospectively assessed the relationship of LTL to SSRI response in MDD. We assessed pre-treatment LTL, depression sever

A soil microbial model to analyze decoupled microbial growth and respiration during soil drying and rewetting

Soils are continuously exposed to cycles of drying and rewetting (D/RW), which drive pronounced fluctuations in soil carbon (C) fluxes. These C dynamics are characterized by a decoupled behavior between microbial biomass synthesis (growth) and CO2 production (respiration). In general, respiration rates peak shortly after RW and subsequently decrease, while the growth peaks lag several hours behind

Quantitative versus standard pupillary light reflex for early prognostication in comatose cardiac arrest patients : an international prospective multicenter double-blinded study

Purpose: To assess the ability of quantitative pupillometry [using the Neurological Pupil index (NPi)] to predict an unfavorable neurological outcome after cardiac arrest (CA). Methods: We performed a prospective international multicenter study (10 centers) in adult comatose CA patients. Quantitative NPi and standard manual pupillary light reflex (sPLR)—blinded to clinicians and outcome assessors—

Climate change and energy policy efforts in Chile: Up in smoke?

Abstract in UndeterminedThe purpose of this study is to preliminarily evaluate Chile’s energy and climate policy performance historically (1971-2007). The objective is to estimate different indicators in relation to energy and CO2 emission intensities, and identify policy instruments in the light of estimated trends and related structural issues. The methodology is based on a top-down decompositio
