OBJECTIVE Robot-assisted stereoelectroencephalography (SEEG) is gaining popularity as a technique for localization of the epileptogenic zone (EZ) in children with pharmacoresistant epilepsy. Here, the authors describe their frameless robot-assisted SEEG technique and report preliminary outcomes and relative complications in children as compared to results with the Talairach frame-based SEEG technique. METHODS The authors retrospectively analyzed the results of 19 robot-assisted SEEG electrode implantations in 17 consecutive children (age < 17 years) with pharmacoresistant epilepsy, and compared these results to 19 preceding SEEG electrode implantations in 18 children who underwent the traditional Talairach frame-based SEEG electrode implantation...

RATIONALE: Past research demonstrates a possible association between herbicide exposure and respiratory health. Biologic plausibility and inhalation as a mode of exposure further support the contention that herbicides may act as adverse contributors to respiratory status, especially in military personnel who were responsible for chemical maintenance and distribution during the Vietnam War. OBJECTIVES: This study examines the association between chronic obstructive pulmonary disease and herbicide exposure among Vietnam-era U...

In this study, we analyse the impact of the organizational culture and introduce a new variable, the integration of safety, which relates to the modalities for the implementation and adoption of safety in the work process, either through the activity or by the operator. One hundred and eighty employees replied to a questionnaire measuring the organizational climate, the safety climate and the integration of safety. We expected that implementation centred on the activity or on the operator would mediate the relationship between the organizational culture and the safety climate...

BACKGROUND: The WHO Surgical Safety Checklist was developed to help operating teams reduce the occurrence of patient harm. The Checklist is a simple, practical tool that any surgical team in the world can use to ensure that the preoperative, intraoperative, and postoperative steps that have been shown to benefit patients are undertaken in a timely and efficient way. METHODS: This study was carried out at Rajarajeswari Medical College Hospital, Bangalore, India, to study the effects of the WHO Surgical Safety Checklist on mortality and morbidity in surgical patients, to identify the potential problems in the long-term implementation of the same, and to document the complications in patients undergoing a major surgery during the study period...

Hydrogen is seen as a sustainable fuel of the future, yet the vast majority of global hydrogen production comes from the reformation of fossil fuels. Electrolytic water splitting using proton exchange membrane electrolysers (PEMEs) provides a pathway to sustainable hydrogen production through coupling to renewable energy sources, but can suffer from gas crossover at low current densities and high operating pressures, causing explosive gas mixtures and decreasing cell lifetimes. Here we demonstrate the application of a highly stable, organic electron-coupled proton buffer (ECPB) which allows the decoupling of hydrogen and oxygen production during water splitting...

BACKGROUND: The factors affecting the safety and efficacy of aminophylline use in the treatment of apnea of prematurity (AOP) in the neonatal intensive care unit (NICU) are not clear. In this study, we aimed to evaluate the potential factors affecting the efficacy and safety of aminophylline in AOP treatment at standard doses and to determine appropriate patients for this therapy. METHODS: Over a 3-year period (January 2012 to December 2014), the medical records of 206 preterm infants with apnea who were admitted to the NICU of our hospital to receive aminophylline infusions were retrospectively reviewed...

Track status classification is essential for the stability and safety of railway operations nowadays, when railway networks are becoming more and more complex and broad. In this situation, monitoring systems are already a key element in applications dedicated to evaluating the status of a certain track section, often determining whether it is free or occupied by a train. Different technologies have already been involved in the design of monitoring systems, including ultrasonic guided waves (UGW). This work proposes the use of the UGW signals captured by a track monitoring system to extract the features that are relevant for determining the corresponding track section status...

OBJECTIVES: Atrial fibrillation (AF) reduces survival and quality of life (QoL). It can be treated at the time of major cardiac surgery using ablation procedures ranging from simple pulmonary vein isolation to a full maze procedure. The aim of this study is to evaluate the impact of adjunct AF surgery as currently performed on sinus rhythm (SR) restoration, survival, QoL and cost-effectiveness. METHODS: In a multicentre, Phase III, pragmatic, double-blinded, parallel-armed randomized controlled trial, 352 cardiac surgery patients with >3 months of documented AF were randomized to surgery with or without adjunct maze or similar AF ablation between 2009 and 2014...

Supercapacitors (SCs) have received a great deal of attention and play an important role for future self-powered devices, mainly owing to their higher power density. Among all types of electrical energy storage devices, electrochemical supercapacitors are considered to be the most promising because of their superior performance characteristics, including short charging time, high power density, safety, easy fabrication procedures, and long operational life. An SC consists of two foremost components, namely electrode materials, and electrolyte...

Hongkun Li, Changbo He, Reza Malekian, Zhixiong Li
The Centrifugal compressor is a piece of key equipment for petrochemical factories. As the core component of a compressor, the blades suffer periodic vibration and flow induced excitation mechanism, which will lead to the occurrence of crack defect. Moreover, the induced blade defect usually has a serious impact on the normal operation of compressors and the safety of operators. Therefore, an effective blade crack identification method is particularly important for the reliable operation of compressors. Conventional non-destructive testing and evaluation (NDT&amp;E) methods can detect the blade defect effectively, however, the compressors should shut down during the testing process which is time-consuming and costly...

BACKGROUND: Hand hygiene is the primary preventive measure against health care-associated infections in terms of cost-effectiveness. In 2005, the WHO proposed the "Global Patient Safety Challenge" campaign, with the aim of reducing the overall incidence of such infections, through multimodal programs and strategies, interactive training tools and standardised methods for monitoring compliance. STUDY DESIGN: On the basis of project "Rimani", sponsored by the Health and Social Care Authority of Emilia-Romagna, the Istituto Ortopedico Gaetano Pini has implemented a project which seeks to increase healthcare staff's compliance with hand hygiene...

BACKGROUND: Diagnostic Therapeutic Pathways (DTPs) are multidisciplinary plans designed by each healthcare organization for a specific category of patients to reduce the variability of professional behaviors and to ensure greater safety and better overall healthcare outcomes. Hip fractures are a frequent traumatic injury, particularly in the elderly, and DTPs recommend early surgical intervention, often not done due to organizational challenges and bureaucracy. Medical conditions suggesting a delay are not frequent, however long waiting times not only increase the risk of complications and mortality, but also increase the number of diagnostic test and physician consultations...

INTRODUCTION: The outcomes of patients treated with colonic stents as a bridge to surgery (BTS) have recently been questioned in terms of safety and long-term oncologic outcomes. The aim of this study is to evaluate the effects on surgical and oncologic outcomes of colonic stents as a BTS for potentially resectable obstructive colorectal cancer. METHODS: We conducted a retrospective analysis of patients operated on for potentially resectable obstructive colorectal cancer with or without distant disease between September 2002 and October 2015, comparing the patients treated with a colonic stent as a BTS (Stent group) with those directly operated on (Surgery group)...
