INTRODUCTION: Patients with acute pulmonary embolism(APE)who present with right ventricular dysfunction (RVD) have a worse prognosis. This study aimed to evaluate the value of routine biochemical parameters in predicting RVD and 30-day mortality in patients with APE. METHODS: We retrospectively collected the clinical data for 154 enrolled patients, including the neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), D-dimer, cardiac troponin I (cTnI), and N-terminal pro-brain natriuretic peptide (NT-proBNP)...

We report a case of cortical blindness secondary to posterior leukoencephalopathy syndrome, which was successfully treated by blood pressure management. A 66-year-old white man presented at the emergency room complaining of severe frontal headache, disorientation, and progressive blurred vision. The initial physical examination disclosed a blood pressure of 200/176 mmHg. One hour later the patient exhibited mental confusion and bilateral blindness. Computed tomography and magnetic resonance imaging were performed, and a systemic workup was conducted, resulting in a diagnosis of posterior leukoencephalopathy syndrome...

Zirconium-89 is an emerging radionuclide for positron emission tomography (PET) especially for biomolecules with slow pharmacokinetics as due to its longer half-life, in comparison to fluorine-18 and gallium-68, imaging at late time points is feasible. Desferrioxamine B (DFO), a linear bifunctional chelator (BFC) is mostly used for this radionuclide so far but shows limitations regarding stability. Our group recently reported on fusarinine C (FSC) with similar zirconium-89 complexing properties but potentially higher stability related to its cyclic structure...

A detailed photophysical picture is elaborated for a structurally well-defined and symmetrical bis-tetracene dimer in solution. The molecule was designed for interrogation of the initial photophysical steps (S1 → (1)TT) in intramolecular singlet fission (SF). (Triisopropylsilyl)acetylene substituents on the dimer TIPS-BT1 as well as a monomer model TIPS-Tc enable a comparison of photophysical properties, including transient absorption dynamics, as solvent polarity is varied. In nonpolar toluene solutions, TIPS-BT1 decays via radiative and nonradiative pathways to the ground state with no evidence for dynamics related to the initial stages of SF...

OBJECTIVES: Among emergency physicians, there is wide variation in admitting practices for patients who suffered a mild traumatic brain injury (TBI) with an intracranial hemorrhage (ICH). The purpose of this study was to evaluate the effects of implementing a protocol in the emergency department (ED) observation unit for patients with mild TBI and ICH. METHODS: This retrospective cohort study was approved by the Institutional Review Board. Study subjects were patients ≥18 years of age with an International Classification of Diseases (ICD) code corresponding to a traumatic IC, and admitted to an ED observation unit (EDOU) of an urban, academic level 1 trauma center between February 1, 2015 and January 31, 2017...

Efficient and effective communication between providers is critical to quality patient care within a hospital system. Hands free communication devices (HFCD) allow instantaneous, closed-loop communication between physicians and other members of a multidisciplinary team, providing a communication advantage over traditional pager systems. HFCD have been shown to decrease emergency room interruptions, improve nursing communication, improve speed of information flow, and eliminate health care waste. We evaluated the integration of an HFCD with an existing alphanumeric paging system on an acute inpatient medicine service...

Community-acquired pneumonia (CAP) is the main cause of death in children under-5 years worldwide and Streptococcus pneumoniae is the most common bacterial agent. However, it is difficult to identify pneumococcal infection among children with CAP. We aimed to assess association between any cytokine/chemokine and pneumococcal infection in childhood CAP. Furthermore, we evaluated the diagnostic value of cytokine/chemokine for pneumococcal infection. This prospective study was conducted at an Emergency Room, in Salvador, Brazil...

Euthanasia was decriminalized in Quebec in December 2015, and Canada-wide in June 2016. Both the Provincial and Federal legislation have limited the right to medical assistance in dying (MAID) to end-of-life cases; which makes MAID inaccessible to most patients solely suffering from psychiatric illness. While some end-stage anorexia nervosa or elderly patients may meet the end-of-life criterion because of their medical comorbidities or their age (Kelly et al., 2003), repeated suicide attempts or psychotic disorganization would not qualify since they would not be seen as elements of an illness leading to a foreseeable "natural death" (Canada, 2016)...

Mobile ultraviolet-C (UV-C) light room decontamination devices are frequently used as an adjunct to standard cleaning in healthcare facilities, but their efficacy in killing Candida species is not clear. In laboratory testing, the emerging multidrug-resistant Candida auris and 2 other Candida species were significantly less susceptible to killing by UV-C than methicillin-resistant Staphylococcus aureus.

INTRODUCTION: Teenagers admitted to the emergency room for a violent attacks episode are increasingly numerous. The source of agitation is multifactorial for these teenagers, often with a complex course. They jeopardize hospital wards, which are often ill-suited for and overwhelmed during these outbursts. This study aims to identify and describe all the teenagers admitted to the hospital over 1 year for a violent outburst and discuss their management. METHODS AND EQUIPMENT: Retrospective and descriptive study of teenagers admitted to the pediatric emergency department of the Nantes University Hospital for a violent outburst in 2015...

Lorena Martín-Olivera, Dmitry G Shchukin, Gilberto Teobaldi
Magnetic hardening and generation of room-temperature ferromagnetism at the interface between originally nonmagnetic transition metals and π-conjugated organics is understood to be promoted by interplay between interfacial charge transfer and relaxation-induced distortion of the metal lattice. The relative importance of the two contributions for magnetic hardening of the metal remains unquantified. Here, we disentangle their role via density functional theory simulation of several models of interfaces between Cu and polymers of different steric hindrance, π-conjugation, and electron-accepting properties: polyethylene, polyacetylene, polyethylene terephthalate, and polyurethane...

WHAT IS KNOWN AND OBJECTIVE: Clomiphene citrate is used to cause ovulation in females and to increase semen production in males. Clomiphene citrate is well tolerated in most patients and rarely induces liver injury. We report a case of liver injury which is associated with administration of clomiphene citrate in a male patient. CASE SUMMARY: A 31-year-old man who was treated by clomiphene citrate for 5 days was transferred to our emergency room with reddish-brown urine and upper abdominal pain...

BACKGROUND: Despite recent advances in surgery and anaesthesia which significantly improve safety, many health facilities in low-and middle-income countries (LMICs) remain chronically under-resourced with inability to cope effectively with serious obstetric complications (Knight et al., PLoS One 8:e63846, 2013). As a result many of these countries still have unacceptably high maternal and neonatal mortality rates. Recent data at the national referral hospitals in East Africa reported that none of the national referral hospitals met the World Federation of Societies of Anesthesiologists (WFSA) international standards required to provide safe obstetric anaesthesia (Epiu I: Challenges of Anesthesia in Low-and Middle-Income Countries...

BACKGROUND: Since the introduction of endotracheal intubation in paediatrics, uncuffed endotracheal tubes (ETTs) have been the standard of care for children under eight years old, based on the presumption that complications, particularly postoperative stridor, are higher with cuffed ETTs. The major disadvantages of uncuffed ETTs cited for this shift in procedure include the difficulty in achieving tidal volumes due to leakage around an uncuffed ETT. To seal the airway adequately, uncuffed tubes may need to be exchanged for another tube with a larger diameter, which sometimes requires several attempts before the appropriate size is found...

Care coordination may be more challenging when the specific physicians with whom primary care physicians (PCPs) are expected to coordinate care change over time. Using Medicare data on physician patient-sharing relationships and the Dartmouth Atlas, we explored the extent to which PCPs tend to share patients with other physicians over time. We found that 70.7% of ties between PCPs and other physicians that were present in 2012 persisted in 2013, and additional shared patients in 2012 increased the odds of being connected in 2013...

The dependent coverage expansion (DCE), a component of the Affordable Care Act, required private health insurance policies that cover dependents to offer coverage for policyholders' children through age 25. This review summarizes peer-reviewed research on the impact of the DCE on the chain of consequences through which it could affect public health. Specifically, we examine the impact of the DCE on insurance coverage, access to care, utilization of care, and health status. All studies find that the DCE increased insurance coverage, but evidence regarding downstream impacts is inconsistent...

BACKGROUND: Turnover among registered nurses (herein referred to as nurses) working in specialty areas of practice can result in a range of negative outcomes. The retention of specialty nurses at the unit level has important implications for hospital and health systems. These implications include lost knowledge and experience which may in turn impact staff performance levels, patient outcomes, hiring, orientating, development of clinical competence and other aspects of organizational performance...

Acute Zika virus (ZIKV) infection is usually mild and self-limiting. Earlier, we reported three cases of fatal acute ZIKV infection in patients without typical signs of ZIKV, but rather with criteria of systemic inflammation response syndrome (SIRS). To follow up these observations, we prospectively included patients at the emergency room with temperature instability and suspected to have acute ZIKV infection, SIRS, or both. A total of 102 patients were included of whom N = 21 (21%) were suspected of acute ZIKV infection, N = 56 (55%) of acute ZIKV infection with SIRS criteria, and N = 25 (24%) of SIRS alone...
