BACKGROUND: Increasing patient-reported outcome measures in the 1980s and 1990s led to the development of recommendations at the turn of the millennium for standardising outcome measures in non-specific low back pain (LBP) trials. Whether these recommendations impacted use is unclear. Previous work has examined citation counts, but actual use and change over time, has not been explored. Since 2011, there has been some consensus on the optimal methods for reporting back pain trial outcomes...

This systematic review evaluates the effectiveness of delayed cord clamping in preterm infants on reducing postdelivery complications of anemia, hemodynamic instability, and the development of intraventricular hemorrhages. Interventions included varying durations of delayed cord clamping with and without cord milking as compared with immediate cord clamping, shorter delays in cord clamping, and delayed cord clamping without cord milking. A comprehensive search of randomized controlled trials, observational, cohort, and before-after studies was conducted between 1946 and 2015 in the electronic databases of Ovid MEDLINE, Embase, and Google Scholar...

BACKGROUND: Palliative care is a holistic framework that is designed to improve quality of life by identifying and treating distressing symptoms of life-threatening or complex conditions. Neonatal palliative care (NPC) has potential benefits for parents, staff, and patients, yet evidence suggests that implementation and utilization of organized NPC services are low. PURPOSE: The purpose of this study is to answer the clinical question: In neonatal intensive care, what evidence can be used to guide implementation of palliative care protocols? SEARCH STRATEGY: A literature search was conducted using CINAHL (Cumulative Index of Nursing and Allied Health Literature), PubMed, and the Cochrane Library databases...

Mitochondrial diseases are a group of genetic disorders that are characterized by defects in oxidative phosphorylation and caused by mutations in genes in the nuclear DNA (nDNA) and mitochondrial DNA (mtDNA) that encode structural mitochondrial proteins or proteins involved in mitochondrial function. Mitochondrial diseases are the most common group of inherited metabolic disorders and are among the most common forms of inherited neurological disorders. One of the challenges of mitochondrial diseases is the marked clinical variation seen in patients, which can delay diagnosis...

Evidence indicates an overrepresentation of youth with co-occurring autism spectrum disorders (ASD) and gender dysphoria (GD). The clinical assessment and treatment of adolescents with this co-occurrence is often complex, related to the developmental aspects of ASD. There are no guidelines for clinical care when ASD and GD co-occur; however, there are clinicians and researchers experienced in this co-occurrence. This study develops initial clinical consensus guidelines for the assessment and care of adolescents with co-occurring ASD and GD, from the best clinical practices of current experts in the field...

BACKGROUND: The objective of this investigation was to develop a self emulsifying drug delivery system (SEDDS) of naproxen, a poorly water soluble drug, which could improve its solubility and oral bioavailability. Methoda: The recent patents on SEDDS of abiraterone acetate (WO2014/009434 A1) and tamoxifen (WO2013/0080083) helped in selecting the naproxen and excipients. Phase diagrams were constructed and the formulations were taken from the micro emulsion region. Formulations were subjected to thermodynamic stability, dispersibility and precipitation tests for optimization...

The SATB2-associated syndrome is a recently described syndrome characterized by developmental delay/intellectual disability with absent or limited speech development, craniofacial abnormalities, behavioral problems, dysmorphic features, and palatal and dental abnormalities. Alterations of the SATB2 gene can result from a variety of different mechanisms that include contiguous deletions, intragenic deletions and duplications, translocations with secondary gene disruption, and point mutations. The multisystemic nature of this syndrome demands a multisystemic approach and we propose evaluation and management guidelines...

Without surveillance studies on mercury (Hg) levels in predominant fish species and parts eaten in a fishing community, the FAO/WHO guidelines might be surpassed, hence health risk. A monitoring study in a developing country with 29 Oreochromis niloticus (Nile tilapia) and 34 Lates niloticus (Nile perch) from landing sites provided muscle, bellyfat and liver samples for Mercury detection using Inductive Couple Plasma-optical emission spectroscopy. The study shows that fish eaten in the fishing community are small with fewer risks from mercury...

In this paper we advance team theory by describing how cognition occurs across the distribution of members and the artifacts and technology that support their efforts. We draw from complementary theorizing coming out of cognitive engineering and cognitive science that views forms of cognition as external and extended and integrate this with theorizing on macrocognition in teams. Two frameworks are described that provide the groundwork for advancing theory and aid in the development of more precise measures for understanding team cognition via focus on artifacts and the technologies supporting their development and use...

Recent studies have highlighted the fact that the enteric microbiome, the trillions of microbes that inhabit the human digestive tract, has a significant effect on health and disease. Methods for manipulating the enteric microbiome, particularly through probiotics and microbial ecosystem transplantation, have undergone some study in clinical trials. We review some of the evidence for microbiome alteration in relation to childhood disease and discuss the clinical trials that have examined the manipulation of the microbiome in an effort to prevent or treat childhood disease with a primary focus on probiotics, prebiotics, and/or synbiotics (ie, probiotics + prebiotics)...

Sleep disturbances are common in adults with PTSD and range from insomnia and nightmares to periodic leg movements and disruptive nocturnal behaviors. Together these findings suggest profound disturbances in rapid eye movement (REM) and non-REM (NREM) sleep, although there is a lack of consensus regarding a distinct profile of objective sleep disturbances associated with PTSD. Prospective, longitudinal studies have established that sleep disturbances represent a risk factor for the development and course of PTSD, suggesting that sleep is an important neurobiological mechanism in the etiology and maintenance of this disorder...

p-Mentha-1,8-dien-7-al is a naturally occurring cyclic alpha,beta-unsaturated aldehyde that is used as a flavoring substance throughout the world. Due to the chemical structure and the potential DNA reactivity of the alpha,beta-unsaturated carbonyl moiety, a battery of genotoxicity assays was requested by the European Food Safety Authority. Previous genotoxicity studies on the substance gave mixed results, but both positive and negative results were hampered by not always being performed to any standard guideline...

BACKGROUND: Observational data have been conflicted regarding the potential role of HIV antiretroviral therapy (ART) as a causative factor for, or protective factor against, COPD. We therefore aimed to investigate the effect of immediate versus deferred ART on decline in lung function in HIV-positive individuals. METHODS: We did a nested substudy within the randomised, controlled Strategic Timing of Antiretroviral Treatment (START) trial at 80 sites in multiple settings in 20 high-income and low-to-middle-income countries...

Localized proton magnetic resonance spectroscopy ((1)H-MRS) is a noninvasive tool for measuring in vivo neurochemical information in animal and human brains. With the increase of magnetic field strength, whereas localized (1)H-MRS benefits from higher sensitivity and spectral dispersion, it is challenged by increased spatial inhomogeneity of the B0 and B1 fields, larger chemical shift displacement error, and shortened T2 relaxation times of metabolites. Advanced localized (1)H-MRS methodologies developed for high magnetic fields have shown promising results and allow the measurement of neurochemical profiles with up to 19 brain metabolites, including less-abundant metabolites, such as glutathione, glycine, γ-aminobutyric acid and ascorbate...

The protein content of breast milk provides a foundation for estimating protein requirements of infants. Because it serves as a guideline for regulatory agencies issuing regulations for infant formula composition, it is critical that information on the protein content of breast milk is reliable. We have therefore carried out a meta-analysis of the protein and amino acid contents of breast milk and how they evolve during lactation. As several bioactive proteins are not completely digested in the infant and therefore represent "non-utilizable" protein, we evaluated the quantity, mechanism of action and digestive fate of several major breast milk proteins...

OBJECTIVE/BACKGROUND: The management of aortic graft infection (AGI) is highly complex and in the absence of a universally accepted case definition and evidence-based guidelines, clinical approaches and outcomes vary widely. The objective was to define precise criteria for diagnosing AGI. METHODS: A process of expert review and consensus, involving formal collaboration between vascular surgeons, infection specialists, and radiologists from several English National Health Service hospital Trusts with large vascular services (Management of Aortic Graft Infection Collaboration [MAGIC]), produced the definition...

INTRODUCTION: Sodium nitroprusside (SNP) enhanced CPR (SNPeCPR) demonstrates increased vital organ blood flow and survival in multiple porcine models. We developed a new, coronary occlusion/ischemia model of prolonged resuscitation, mimicking the majority of out-of-hospital cardiac arrests presenting with shockable rhythms. HYPOTHESIS: SNPeCPR will increase short term (4-hour) survival compared to standard 2015 Advanced Cardiac Life Support (ACLS) guidelines in an ischemic refractory ventricular fibrillation (VF), prolonged CPR model...
