#1
Weiwei An, Ralph P Mason, Alexander R Lippert
Chemiluminescence imaging offers a low background and high sensitivity approach to imaging analytes in living cells and animals. Intensity-based measurements have been developed, but require careful consideration of kinetics, probe localization, and fluctuations in quantum yield, all of which complicate quantification. Here, we report a ratiometric strategy for quantitative chemiluminescence imaging of pH. The strategy relies on an energy transfer cascade of chemiluminescence emission from a spiroadamantane 1,2-dioxetane to a ratiometric pH indicator via fluorescent dyes in Enhancer solutions...

Objectives: Behavioural and psychological symptoms of dementia (BPSD) cause significant distress to both aged care residents and staff. Despite the high prevalence of BPSD in progressive neurological diseases (PNDs) such as multiple sclerosis, Huntington's disease, and Parkinson's disease, the utility of a structured clinical protocol for reducing BPSD has not been systematically evaluated in PND populations. Method: Staff ( n = 51) and individuals with a diagnosis of PND ( n = 13) were recruited into the study, which aimed to evaluate the efficacy of a PND-specific structured clinical protocol for reducing the impact of BPSD in residential aged care (RAC) and specialist disability accommodation (SDA) facilities...

Antithrombin [AT] is the main inhibitor for activated plasma coagulation serine esterases, inhibiting thrombin, Factors Xa and IXa, but also Factors XIIa, XIa, VIIa, kallicrein, and plasmin. Its activity is highly enhanced by heparin, through binding to the pentasaccharide sequences, for inhibition of all coagulation proteases, except thrombin, which inhibition requires its additional binding to the heparin polysaccharide chain. However, AT is the major inhibitor of thrombin in the blood circulation. Congenital or acquired deficiencies of AT expose affected patients to an increased risk of developing unprovoked and recurrent thrombo-embolic diseases...

Treatment of opioid use disorder often begins with brief intensive inpatient or outpatient programs. Given the high relapse rates following intensive treatment, it is important to determine factors that lead to success post-discharge. Incorporating assessment during and early post-discharge may help determine such factors. The current study evaluated changes in quality of life among individuals during and after discharge from inpatient and partial hospitalization opiate treatment programs. Participants (n = 143) were recruited while in the programs and were re-assessed one month later (n = 113)...

Nosocomial, hospital-acquired or health care-associated infections occur worldwide, affecting both developed and developing countries. This results in a prolonged hospital stay, increased antimicrobial resistance, increased mortality rate, and significant financial burden on the health care system. Routine preventive measures have led to the decrease in infection spreading; however, it cannot successfully prevent all of them, making a place for the development of new strategies, including probiotics. The aim of this review was to summarize available evidence of the role of probiotics in the prevention of nosocomial infections in children...

BACKGROUND: Epidural analgesia is a central nerve block technique achieved by injection of a local anaesthetic close to the nerves that transmit pain, and is widely used as a form of pain relief in labour. However, there are concerns about unintended adverse effects on the mother and infant. This is an update of an existing Cochrane Review (Epidural versus non-epidural or no analgesia in labour), last published in 2011. OBJECTIVES: To assess the effectiveness and safety of all types of epidural analgesia, including combined-spinal-epidural (CSE) on the mother and the baby, when compared with non-epidural or no pain relief during labour...

Although the role of B cells in sepsis immunoregulation has become an interesting topic, there is lack of data on the role of B cell function regulators in prediction of multiorgan dysfunction syndrome (MODS). The aim of this study was to evaluate the prognostic value of A Proliferation Inducing Ligand (APRIL) and soluble Transmembrane Activator and CAML Interactor Protein (sTACI), the main B cell function regulators, in prediction of MODS development within the first 48h after admission to intensive care unit, among septic patients...

Anti-N-methyl-D-aspartate receptor (anti-NMDAR) encephalitis is a recently described auto-immune and paraneoplastic encephalitis with prominent neuropsychiatric manifestations affecting young adults with ovarian teratoma. The availability of a novel assay to measure these antibodies might suggest an etiology for this potentially life-threatening disease, which if early recognized can be treated promptly with surgery with chances of a good clinical outcome. Reported prognostic indicators for a good outcome depend on the presence of a tumor, prompt treatment and no admission to an intensive care unit...

INTRODUCTION: Neonatal intensive care units (NICUs) have complex patients in terms of their diagnoses and required treatments. Antimicrobial treatment is a common therapy for patients in NICUs. To solve problems pertaining to empirical therapy, antimicrobial stewardship programs have recently been introduced. Despite the success of these programs in terms of data collection, there is still inefficiency in terms of analyzing and reporting the data. Thus, to successfully implement these stewardship programs, the design of antimicrobial resistance (AMR) surveillance systems is recommended as a first step...

A simple and precise ultra-performance liquid chromatography-tandem mass spectrometry (UPLC-MS/MS) method was developed for the simultaneous analysis of five anti-infective agents used to treat severe infections [three antibiotics (daptomycin, moxifloxacin, ciprofloxacin) and two antifungals (isavuconazole, caspofungin)] in human plasma. Sample preparation was based on protein precipitation with ice cold methanol. All five agents were analyzed with the corresponding isotopically labeled internal standards. All analytes were detected in multiple reactions monitoring (MRM) using API 4000 triple-quadrupole mass spectrometer with electrospray (ESI) source operating in positive mode...

BACKGROUND & AIMS: Measuring resting energy expenditure (REE) via indirect calorimetry (IC) in intensive care unit (ICU) patient is the gold standard recommended by guidelines. However technical difficulties hinder its use and predictive equations are largely used instead. We sought to validate commonly used equations using a large cohort of patients. METHODS: Patients hospitalized from 2003 to 2015 in a 16-bed ICU at a university-affiliated, tertiary care hospital who had IC measurement to assess caloric targets were included...

The measurement of vitamin D-binding protein (VDBP) by immunoassay has been confounded by variable antibody recognition of the Gc1s, Gc1F and Gc2 phenotypes. This has led to spurious conclusions regarding vitamin D status in different ethnic groups. In order to overcome these problems there is a requirement for VDBP antibodies that are unaffected by phenotype status. Here we report the generation and testing of three monoclonal antibodies to VDBP which recognise linear epitopes and are unaffected by vast molar excesses of synthetic peptides spanning these phenotypic domains...

PROBLEM: Mindfulness training includes mindfulness meditation, which has been shown to improve both attention and self-awareness. Medical providers in the intensive care unit often deal with difficult situations with strong emotions, life-and-death decisions, and both interpersonal and interprofessional conflicts. The effect of mindfulness meditation training on healthcare providers during acute care tasks such as cardiopulmonary resuscitation remains unknown. Mindfulness meditation has the potential to improve provider well-being and reduce stress in individuals involved in resuscitation teams, which could then translate into better team communication and delivery of care under stress...
