Part 2: Evidence Evaluation and Management of Conflicts of Interest: 2015 American Heart Association Guidelines Update for Cardiopulmonary Resuscitation and Emergency Cardiovascular Care.

This Part describes the process of creating the 2015 American Heart Association (AHA) Guidelines Update for Cardiopulmonary Resuscitation (CPR) and Emergency Cardiovascular Care (ECC), informed by the 2015 International Consensus on CPR and ECC Science With Treatment Recommendations (CoSTR) publication.1,2 The process for the 2015 International Liaison Committee on Resuscitation (ILCOR) systematic review is quite different when compared with the process used in 2010.1–3 For the 2015 systematic review process, ILCOR used the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) (www.gradeworkinggroup.org) approach to systematic reviews and guideline development. For the development of this 2015 Guidelines Update, the AHA used the ILCOR reviews as well as the AHA definition of Classes of Recommendation (COR) and Levels of Evidence (LOE) (Table 1). This Part summarizes the application of the ILCOR GRADE process to inform the creation of 2015 Guidelines Update, and the process of assigning the AHA COR and LOE. View this table: Table 1. Applying Class of Recommendations and Level of Evidence to Clinical Strategies, Interventions, Treatments, or Diagnostic Testing in Patient Care* ### Grading of Recommendations Assessment, Development, and Evaluation The 2015 CoSTR summarizes the published scientific evidence that was identified to answer specific resuscitation questions. ILCOR uses the GRADE system to summarize evidence and determine confidence in estimates of effect as well as to formulate treatment recommendations. GRADE is a consensus-crafted tool in wide use by many professional societies and reference organizations, including the American College of Physicians, the American Thoracic Society, and the Cochrane Collaboration, as well as the Centers for Disease Control and the World Health Organization. The choice of the GRADE approach was based on its increasingly ubiquitous use, practicality, and unique features. To our knowledge, the ILCOR evidence review process represents the largest application of the GRADE system in a healthcare-related review. GRADE is a system to review evidence to determine …
Effects of urinary and recombinant gonadotrophins on gene expression profiles during the murine peri-implantation period.

BACKGROUND Controlled ovarian stimulation (COS) with urinary gonadotrophins but not recombinant gonadotrophins, adversely affect the implantation process. In this study, we investigated the effects of urinary and recombinant gonadotrophins on gene expression profiles at implantation sites during the mouse peri-implantation period and the possible molecular mechanisms involved in the detrimental effects of urinary gonadotrophins using microarray technology. METHODS Adult female CD1 mice were treated with (i) urinary human FSH (hFSH) and urinary HCG, (ii) recombinant hFSH and recombinant human LH or (iii) saline. Gene expression profiling with GeneChip mouse genome 430 2.0 arrays, containing 45 101 probe sets, was performed using implantation sites on embryonic day 5. Data were statistically analysed using Significance Analysis of Microarrays. Ten genes from the microarray analysis were selected for validation using quantitative RT-PCR (qRT-PCR). A parallel group of pregnant mice was allowed to give birth to study the effect of gonadotrophins on resorption. RESULTS Urinary gonadotrophins differentially up-regulated the expression of 30 genes, increased resorption and reduced litter size, whereas recombinant gonadotrophins did not. Nine of the 10 genes were confirmed by qRT-PCR. CONCLUSIONS Urinary gonadotrophins, but not recombinant gonadotrophins, exerted differential effects on gene expression during the murine peri-implantation period. These findings might contribute to improve protocols for COS, leading to higher successful pregnancy rates.
Increased Risk of Acute Hepatitis B among Adults with Diagnosed Diabetes Mellitus

Introduction: The risk of acute hepatitis B among adults with diabetes mellitus is unknown. We investigated the association between diagnosed diabetes and acute hepatitis B. Methods: Confirmed acute hepatitis B cases were reported in 2009–2010 to eight Emerging Infections Program (EIP) sites; diagnosed diabetes status was determined. Behavioral Risk Factor Surveillance System respondents residing in EIP sites comprised the comparison group. Odds ratios (ORs) comparing acute hepatitis B among adults with diagnosed diabetes versus without diagnosed diabetes were determined by multivariate logistic regression, adjusting for age, sex, and race/ethnicity, and stratified by the presence or absence of risk behaviors for hepatitis B virus (HBV) infection. Results: During 2009–2010, EIP sites reported 865 eligible acute hepatitis B cases among persons aged ≥23 years; 95 (11.0%) had diagnosed diabetes. Comparison group diabetes prevalence was 9.1%. Among adults without hepatitis B risk behaviors and with reported diabetes status, the OR for acute hepatitis B comparing adults with and without diabetes was 1.9 (95% confidence interval [CI] = 1.4, 2.6); ORs for adults ages 23–59 and ≥60 years were 2.1 (95% CI = 1.6, 2.8) and 1.5 (95% = CI 0.9, 2.5), respectively. Conclusions: Diabetes was independently associated with an increased risk for acute hepatitis B among adults without HBV risk behaviors.
Do Women Manage Smaller Funds?

Based on a sample of 467 asset managers from four countries we robustly find that women manage smaller funds than men, despite tough competition in this industry. Interestingly, the gender gap exists only for managers of smaller funds, i.e. at the lower end of the hierarchy, as quantile regressions show. This is inconsistent with the glass ceiling hypothesis. Going further, this gender gap is limited to large firms. Explanations may refer to large firms using market power in the area of smaller funds or to ‘visibility’ among top asset managers protecting against unequal treatment of the sexes.
Stereotactic recordings of median nerve somatosensory‐evoked potentials in the human pre‐supplementary motor area

Median nerve somatosensory‐evoked potentials (SEPs) have been recorded using intracortical electrodes stereotactically implanted in the frontal lobe of eight epileptic patients in order to assess the waveforms, latencies and surface‐to‐depth distributions of somatosensory responses generated in the anterior subdivision of supplementary motor areas (SMAs), the so‐called pre‐SMA. Intracortical responses were analysed in two latency ranges: 0–50 ms and 50–150 ms after stimulus. In all patients, we recorded in the first 50 ms after stimulus two positive P14 and P20 potentials followed by a N30 negativity. In the hemisphere contralateral to stimulation, the P20–N30 potentials showed a clear amplitude decrease from the outer to the inner aspect of the frontal lobe with minimal amplitudes in the pre‐SMA. In the hemisphere ipsilateral to stimulus, P20 and N30 amplitudes were decreasing from mesial to lateral frontal cortex. In the 50–150 ms latency range, contacts implanted in the pre‐SMA recorded a negative potential in the 60–70 ms latency range which, in five patients, was followed by a positive response peaking 80–110 ms after stimulus. These potentials were not picked up by more superficial contacts. We conclude that no early SEP is generated in pre‐SMA in the first 50 ms after stimulation, while some potentials peaking in the 60–100 ms after stimulus are likely to originate from this cortical area. The latency of the pre‐SMA responses recorded in our patients supports the hypothesis that the pre‐SMA does not receive short‐latency somatosensory inputs via direct thalamocortical projections. More probably the pre‐SMA receives somatosensory inputs mediated by a polysynaptic transcortical transmission through functionally secondary motor and somatosensory areas.
The soluble D2D388-274 fragment of the urokinase receptor inhibits monocyte chemotaxis and integrin-dependent cell adhesion

We have previously shown that chymotrypsin-cleaved soluble uPAR (D2D388-274) elicits migration of monocytic cells through interaction with FPRL-1, a G protein-coupled receptor that is homologous to the fMLP receptor. Here, we report that D2D388-274 also modulates the ability of monocytes to migrate in response to other chemokines. Pretreatment of monocytes with increasing amounts of D2D388-274 prevents cell migration in response to MCP-1, RANTES and fMLP. We demonstrate that D2D388-274 does not inhibit MCP-1 receptor binding, elicit CCR2 internalization and prevent MCP-1-induced intracellular Ca2+ increase. Thus, CCR2 receptor desensitization cannot account for D2D388-274-mediated inhibition of MCP-1-induced cell migration. Rather, we show that pretreatment of monocytes with D2D388-274 dramatically decreases chemokine-induced integrin-dependent rapid cell adhesion by interacting with FPRL-1. Together, our results indicate that chemokine-dependent cell migration can be regulated not only by homologous and heterologous receptor desensitization, but also by inhibition of integrin-dependent cell adhesion, an important step in cell transmigration.
The use of event-related potential (P300) and neuropsychological testing to evaluate cognitive impairment in mild traumatic brain injury patients

Background: The aim of the study is to compare the amplitude and latency of the P300 event-related potential (ERP) component between a control group and patients after mild traumatic brain injury (mTBI) during 1–7 days (short duration) and 2–3 months (long duration), and to compare the outcome of neuropsychological tests between the long duration postinjury and control study groups. Materials and Methods: We studied responses to auditory stimulation in two main and one subgroups, namely the control healthy group (19 patients, both ERP and neuropsychology test done), the mTBI 1 group (17 patients, only ERP done within 7 days after injury), and the mTBI 2 subgroup (the 17 mTBI 1 patients in whom a repeated ERP together with neuropsychological testing was done at 2–3 months postinjury). Auditory evoked responses were studied with two different stimuli (standard and target stimuli), where the P300 amplitude and latency were recorded from three midline sites and results were compared between the groups, as were the neuropsychological test results. Results: There was a significant prolongation of the target P300 latency values shown by the MBI 1 group measured at the central electrode when compared to the control group, which was also seen when the mTBI 1 and mTBI 2 groups were compared. The results of the P300 amplitude values measured at the frontal electrode showed the control group to have higher readings during the presentation of standard tones when compared to the mTBI 1 group. The mTBI 2 group performed better on some neuropsychological tests. Conclusion: The latency of P300 was significantly prolonged in early mTBI patients who improved over time, and the neuropsychological testing on mTBI 2 patients showed them to be comparable to the control group. The study indicates that ERP should be used as an additional modality of investigation in mTBI patients.
Clinical presentation and survival of retinoblastoma in Indian children

Objective To study the clinical presentation and survival among Indian children with retinoblastoma (RB) and to determine factors predictive of poor outcome. Methods A retrospective review of children newly diagnosed with RB at a tertiary referral centre was undertaken. Demographic and clinical characteristics and treatment outcomes were studied. Results A total of 600 patients (unilateral 67.6%, bilateral 32.4%) was studied. 61% was boys. The median age at presentation was 29 months (18 months vs 36 months in bilateral and unilateral cases, respectively, p<0.001). leukocoria was most common (83%), followed by proptosis (17%). Tumours were intraocular in 72.3% and extraocular in 27.7% cases. In the intraocular group, 78% were advanced Group D or E disease. Metastasis to the central nervous system was noted in 15.7% of extraocular cases. A statistically significant difference was seen between intraocular and extraocular groups in the median age (24 months vs 37.5 months, p<0.001) and median lag period (2.5 months vs 7 months, p<0.001). The Kaplan-Meier survival probability was 83%, 73% and 65% at 1 year, 2 years and 5 years, respectively. On univariate analysis, age >2 years (p=0.002), lag period >6 months (p=0.004) and extraocular stage (p<0.001) were associated with poor outcome. On multivariate analysis, extraocular invasion was predictive of low survival (HR 5.04, p<0.001). Conclusions Delayed presentation is a matter of concern. Improving awareness about the early signs and creating facilities for diagnosing and treating RB at the primary and secondary levels of healthcare are required to reduce mortality and morbidity, and lead to improved outcomes that are comparable with the developed nations.
C 242 T polymorphism of the p 22 phox gene is not associated with peripheral arterial occlusive disease

Formation of reactive oxygen metabolites is vital for the microbicidal activity of phagocytes. As an unwanted side effect, these metabolites may contribute to oxidative stress in the vasculature and thus lead to arteriosclerosis. p22 phox, a component of the NADH/NADPH oxidase in phagocytes and vascular smooth muscle cells, is essential for production of reactive oxygen metabolites. Recently, a C/T polymorphism at position 242 of the p22 phox gene has been associated with coronary artery disease (CAD), suggesting a protective effect of the 242 T allele on the vasculature. In the present study, we analysed the relation of this polymorphism to peripheral arterial occlusive disease (PAOD). C242T polymorphism was determined by restriction fragment polymorphism (RFLP) analysis in 324 patients with documented PAOD and 295 control subjects without any known arterial disease. p22 phox 242 T allele frequencies and genotype distributions were not significantly different between patients and controls; the adjusted relative risk associated with the 242 T allele was 1.14 (95% CI 0.84–1.54, P=0.39), assuming an additive effect of the T allele. C242T polymorphism was not associated with the age of patients at the onset of the disease. Our data indicate that C242T polymorphism of the p22 phox gene is not associated with PAOD. © 2000 Elsevier Science Ireland Ltd. All rights reserved.
Biallelic mutations in LARS2 can cause Perrault syndrome type 2 with neurologic symptoms

Perrault syndrome represents a genetically heterogeneous disorder characterized by sensorineural hearing loss in males and females and ovarian dysfunction in females. Causative genes include HARS2, HSD17B4, CLPP, C10orf2, and LARS2. Some patients with Perrault syndrome exhibit neurologic features including learning disability, cerebellar ataxia, and peripheral neuropathy and are classified as type 2 and are clinically separate from those without neurological symptoms other than a hearing loss (type 1). To date, all reported patients with LARS2 mutations (15 patients in 8 families) have been classified as type 1. Here, we report female siblings with biallelic mutations in LARS2, p.Glu294Lys, and p.Thr519Met, who were classified as type 2. The proposita developed progressive sensorineural hearing loss at 18 months and pervasive developmental disorder at 8 years, with repetitive behavior, insistence on sameness, attention deficit, tic, irritability, and an ataxic gait. At age 15 years, she was diagnosed as having primary amenorrhea with elevated FSH and LH and a decreased estradiol; ultrasound and magnetic resonance imaging examinations revealed a small uterus and no detectable ovaries. The proposita's younger sister presented with neonatal sensorineural hearing loss and a mild delay in motor and speech development. She was diagnosed as having primary amenorrhea with endocrinologic and radiographic findings that were comparable to those of her sister. She had difficulty with reading comprehension, and had trouble with open‐ended test questions at 12 years of age. We concluded that Perrault syndrome patients with LARS2 mutations are at risk for neurologic problems, despite previous notions otherwise.
Unravelling genetics at the top: mountain islands or isolated belts?

BACKGROUND AND AIMS In mountain plant populations, local adaptation has been described as one of the main responses to climate warming, allowing plants to persist under stressful conditions. This is especially the case for marginal populations at their lowest elevation, as they are highly vulnerable. Adequate levels of genetic diversity are required for selection to take place, while high levels of altitudinal gene flow are seen as a major limiting factor potentially precluding local adaptation processes. Thus, a compromise between genetic diversity and gene flow seems necessary to guarantee persistence under oncoming conditions. It is therefore critical to determine if gene flow occurs preferentially between mountains at similar altitudinal belts, promoting local adaptation at the lowest populations, or conversely along altitude within each mountain. METHODS Microsatellite markers were used to unravel genetic diversity and population structure, inbreeding and gene flow of populations at two nearby altitudinal gradients of Silene ciliata, a Mediterranean high-mountain cushion plant. KEY RESULTS Genetic diversity and inbreeding coefficients were similar in all populations. Substantial gene flow was found both along altitudinal gradients and horizontally within each elevation belt, although greater values were obtained along altitudinal gradients. Gene flow may be responsible for the homogeneous levels of genetic diversity found among populations. Bayesian cluster analyses also suggested that shifts along altitudinal gradients are the most plausible scenario. CONCLUSIONS Past population shifts associated with glaciations and interglacial periods in temperate mountains may partially explain current distributions of genetic diversity and population structure. In spite of the predominance of gene flow along the altitudinal gradients, local genetic differentiation of one of the lower populations together with the detection of one outlier locus might support the existence of different selection forces at low altitudes.
Unsupervised Ship Detection Based on Saliency and S-HOG Descriptor From Optical Satellite Images

With the development of high-resolution imagery, ship detection in optical satellite images has attracted a lot of research interest because of the broad applications in fishery management, vessel salvage, etc. Major challenges for this task include cloud, wave, and wake clutters, and even the variability of ship sizes. In this letter, we propose an unsupervised ship detection method toward overcoming these existing issues. Visual saliency, which focuses on highlighting salient signals from scenes, is applied to extract candidate regions followed by a homogeneous filter presented to confirm suspected ship targets with complete profiles. Then, a novel descriptor, ship histogram of oriented gradient, which characterizes the gradient symmetry of ship sides, is provided to discriminate real ships. Experimental results on numerous panchromatic satellite images demonstrate the good performance of our method compared to state-of-the-art methods.
The influence of labour on the pharmacokinetics of intravenously administered amoxicillin in pregnant women.

AIMS Many physiological changes take place during pregnancy and labour. These might change the pharmacokinetics of amoxicillin, necessitating adjustment of the dose for prevention of neonatal infections. We investigated the influence of labour on the pharmacokinetics of amoxicillin. METHODS Pregnant women before and during labour were recruited and treated with amoxicillin intravenously. A postpartum dose was offered. Blood samples were obtained and amoxicillin concentrations were determined using high-pressure liquid chromatography. The pharmacokinetics were characterized by nonlinear mixed-effects modelling using NONMEM. RESULTS The pharmacokinetics of amoxicillin in 34 patients was best described by a three-compartment model. Moderate interindividual variability was identified in CL, central and peripheral volumes of distribution. The volume of distribution (V) increased with an increasing amount of oedema. Labour influenced the parameter estimate of peripheral volume of distribution (V(2)). V(2) was decreased during labour, and even more in the immediate postpartum period. For all patients the population estimates (mean +/- SE) for CL and V were 21.1 +/- 4.1 l h(-1) (CL), 8.7 +/- 6.6 l (V(1)), 11.8 +/- 7.7 l (V(2)) and 20.5 +/- 15.4 l (V(3)) respectively. CONCLUSIONS The peripheral distribution volume of amoxicillin in pregnant women during labour and immediately postpartum is decreased. However, these changes are not clinically relevant and do not warrant deviations from the recommended dosing regimen for amoxicillin during labour in healthy pregnant patients.
DECREASED IL-12 PRODUCTION BY POLYMORPHONUCLEAR LEUKOCYTES IN PATIENTS WITH ACTIVE SYSTEMIC LUPUS ERYTHEMATOSUS

Polymorphonuclear leukocytes (PMN) play an important role in eradicating bacterial infections. To test if PMN of patients with systemic lupus erythematosus (SLE) have defective capacity to produce IL-12, IL-12 p35 gene transcription and p70 excretion by PMN were evaluated in SLE patients and normal subjects. Peripheral blood PMN from 25 patients with active SLE and 25 normal individuals were stimulated with lipopolysaccharide (LPS, 100 ng/mL) in the presence or absence of recombinant interferon (IFN)-γ (5–200 IU/mL). The IL-12 p35 gene transcripts were analyzed by reverse transcription – polymerase chain reaction (RT-PCR) and the IL-12 p70 in culture supernatants was quantified by enzyme immunoassay (EIA). At the 6th hour of stimulation, IL-12 expression in PMN of SLE patients was less prominent than that of the normal controls. The IL-12 was produced by normal PMN on LPS stimulation in the absence of IFN-γ. IFN-γ enhanced the IL-12 production by normal PMN stimulated with LPS, but it inhibited the IL-12 production in PMN from active lupus patients in the presence of LPS. Analysis with PCR using the same primers on the chromosomal DNA showed that p35 gene was intact in SLE patients. These results have suggested that SLE-PMN may have defect in IL-12 expression and the defect may be exaggerated in the presence of IFN-γ which normally stimulates IL-12 production. This may account for increased susceptibility to multiple infections in patients with active SLE.
Effect of some irritants on human epidermal mitosis

Studies on how irritant materials might induce epidermal hyperplasia were initiated by investigating their influence on epidermal mitosis. 5 % hydrochloric acid, neat dimethyl acetamide and 1 % benzalkonium chloride had no effect. 5 % benzalkonium chloride, however, produced a 10‐fold increase in mitotic activity, while a dose response curve was seen with sodium lauryl sulphate (SLS) peaking at 1 %, 1 % SLS produced a remarkably uniform response for this type of assay and it is suggested that it might provide a useful model for situations of increased epidermal cell turnover such as psoriasis. It is also noted that there was apparently no direct relationship between gross inflammation and the mitotic response.
