BACKGROUND: To improve survival of patients resuscitated from out of hospital cardiac arrest (OCHA), data is needed to assess and improve inpatient post-resuscitation care. Our objective was to apply probabilistic linkage methodology to link EMS and inpatient databases and evaluate whether it may be used to describe post-arrest care in Michigan. METHODS: We performed a retrospective study to describe post-cardiac arrest care in adult OHCA patients who were transported to Michigan hospitals from July 1, 2010, to June 30, 2013...

Cochlear implantation can restore a certain degree of auditory impression of patients suffering from profound hearing loss or deafness. Furthermore, studies have shown that in case of residual hearing, patients benefit from the use of a hearing aid in addition to the cochlear implant. The presented studies aim at the improvement of this electromechanical stimulation (EMS) approach by substituting the external hearing aid by an internal stimulus provided by miniaturized piezoelectric actuators. Finite element analyses are performed in order to derive fundamental guidelines for the actuator layout aiming at maximal mechanical stimuli...

OBJECTIVE: Dynamic ambulance redeployment policies tend to introduce much more flexibilities in improving ambulance resource allocation by capitalizing on the definite geospatial-temporal variations in ambulance demand patterns over the time-of-the-day and day-of-the-week effects. A novel modelling framework based on the Approximate Dynamic Programming (ADP) approach leveraging on a Discrete Events Simulation (DES) model for dynamic ambulance redeployment in Singapore is proposed in this paper...

INTRODUCTION: The cumulative burden of chronic health conditions could contribute to out-of-hospital cardiac arrest (OHCA) physiology and response to attempted resuscitation. Yet little is known about how chronic health conditions influence prognosis. We evaluated the relationship between cumulative comorbidity and outcome following ventricular fibrillation OHCA using 3 different scales. METHODS: We performed a cohort investigation of persons >=18years who suffered non-traumatic OHCA and presented with ventricular fibrillation between January 1, 2007 and December 31, 2013 in a metropolitan emergency medical service (EMS) system...

BACKGROUND: Mortality from out-of-hospital cardiac arrest (OHCA) is characterized by substantial regional variation. The Institute of Medicine (IOM) recently recommended enhancing the capabilities of EMS systems to improve outcome. In this study, we analyzed the trend in outcome from ventricular fibrillation/pulseless ventricular tachycardia (VF/pVT) OHCA in Rochester, MN. Survival from these forms of arrest is commonly employed as a benchmark of Emergency Medical Services (EMS) system performance...

OBJECTIVES: The Utstein ten-step implementation strategy (UTIS) proposed by the Global Resuscitation Alliance, a bundle of community cardiopulmonary resuscitation (CPR) programs to improve outcomes after out-of-hospital cardiac arrests (OHCAs), has been developed. However, it is not documented whether UTIS programs are associated with better outcomes or not. The study aimed to test the association between the UTIS programme and better outcomes after OHCA. METHODS: The study was a before- and after-intervention study...

Radish (Raphanus sativus L. var. sativus), a widely cultivated root vegetable crop, possesses a large sink organ (the root), implying that photosynthetic activity in radish can be enhanced by altering both the source and sink capacity of the plant. However, since radish is a self-incompatible plant, improved mutation-breeding strategies are needed for this crop. TILLING (Targeting Induced Local Lesions IN Genomes) is a powerful method used for reverse genetics. In this study, we developed a new TILLING strategy involving a two-step mutant selection process for mutagenized radish plants: the first selection is performed to identify a BC1M1 line, that is, progenies of M1 plants crossed with wild-type, and the second step is performed to identify BC1M1 individuals with mutations...

BACKGROUND: Emergency Medical Services (EMS) providers, who perform initial assessments of ill and injured patients, often in a patient's home, are uniquely positioned to identify potential victims of elder abuse, neglect, or self-neglect. Despite this, few organized programs exist to ensure that EMS concerns are communicated to or further investigated by other health care providers, social workers, or the authorities. OBJECTIVE: To explore attitudes and self-reported practices of EMS providers surrounding identification and reporting of elder mistreatment...

Spatial attention improves perception of attended parts of a scene, a behavioral enhancement accompanied by modulations of neuronal firing rates. These modulations vary in size across neurons in the same brain area. Models of normalization explain much of this variance in attention modulation with differences in tuned normalization across neurons (Lee J, Maunsell JHR. PLoS One 4: e4651, 2009; Ni AM, Ray S, Maunsell JHR. Neuron 73: 803-813, 2012). However, recent studies suggest that normalization tuning varies with spatial location both across and within neurons (Ruff DA, Alberts JJ, Cohen MR...

BACKGROUND: In the Netherlands prehospital trauma care is provided by emergency medical services (EMS) nurses. This care is extended by Physician staffed Helicopter Emergency Medical Services (P-HEMS) for the more severely injured patient. Prehospital communication is a factor of influence on the identification of these patients and the dispatch of P-HEMS. Though prehospital communication it is often perceived to be incomplete and unstructured. To elucidated factors of influence on prehospital triage and the identification of the severely injured patient a Delphi study was performed...

In recent years, there have been many reports about the efficacy of stenting for central bronchial stenosis. When central bronchial stenosis is due to metastasis of a malignant tumor to the trachea and/or bronchi (endobronchial metastasis: EM), it is classified as "narrow EM" and "broad EM." [1] We managed two patients in whom bilateral stent placement was required for narrow and broad EM arising from colorectal cancer. Case 1: In September 2011, a 66-year-old man underwent low anterior resection for advanced colorectal cancer associated with unresectable liver metastasis...

INTRODUCTION: On 22 July 2011, Norway suffered a devastating terrorist attack targeting a political youth camp on a remote island. Within a few hours, 35 injured terrorist victims were admitted to the local Ringerike community hospital. All victims survived. The local emergency medical service (EMS), despite limited resources, was evaluated by three external bodies as successful in handling this crisis. This study investigates the determinants for the success of that EMS as a model for quality improvement in healthcare...

Out of hospital cardiac arrest (OHCA) remains a major cause of morbidity and mortality. The survival rates are poor and even more frustrating are the rates of neurologically favorable outcomes at hospital discharge. In a recent IJHPR article, Einav et al. concluded that many primary care clinics are underequipped and the physicians underprepared to initiate life-saving services. The chance of having an OHCA in a primary care clinic is very low. But although the impact is small, primary care teams as well as other out-of-hospital healthcare personal should be familiar with the telephone number for summoning emergency medical services (EMS), be aware of the location of the defibrillator in their clinic, and know how to use it...

INTRODUCTION: Out of hospital cardiac arrest (OHCA) occurs frequently and the outcome is often dismal. Early defibrillation saves lives and brain function in OHCA. The Zurich city police (STAPO) forces were instructed and equipped to provide basic life support (BLS) and to use an AED in 2009. METHODS: Retrospective observational study comparing period 1 (P1) 2004-2009 before equipping and training of the STAPO and period 2 (P2) 2010-2015 after the implementation...
