Authors: Hu Peng , Xu Xuebing , Yu Liangli 
Published: April 2017

AbstractAcer truncatum seed oil rich in nervonic acid was extracted using supercritical carbon dioxide. GC (Gas Chromatography) analysis revealed that the oil contained approximately 6.22% nervonic acid. The sn‐2 compositions were also determined using lipase hydrolysis. A total of 52 triacylglycerides (TAG) were tentatively identified in the oil using an ultra‐performance convergence chromatography (UPC2) coupled with quadrupole time‐of‐flight mass spectrometry (Q‐TOF‐MS) for the first time. In addition, the contents of phytosterols (1961.9–2402.8 μmol/kg) and β‐carotene (2.09–2.35 μmol/kg) were also quantified for the first time, along with tocopherols (2352.0–2654.3 μmol/kg). The γ‐tocopherol (1296.9‐1442.3 μmol/kg) was the primary tocopherol, while β‐sitosterol (1355.2–1631.3 μmol/kg) was the dominant phytosterol. The physicochemical properties of the oil were also investigated. This study indicated that A. truncatum seed oil is rich in nervonic acid and other nutraceutical constituents. It has a high potential in functional foods for improving human health.
Patient healthcare trajectory. An essential monitoring tool: a systematic review
Authors: Pinaire Jessica , Azé Jérôme , Bringay Sandra , Landais Paul 
Published: April 2017

AbstractBackgroundPatient healthcare trajectory is a recent emergent topic in the literature, encompassing broad concepts. However, the rationale for studying patients’ trajectories, and how this trajectory concept is defined remains a public health challenge. Our research was focused on patients’ trajectories based on disease management and care, while also considering medico-economic aspects of the associated management. We illustrated this concept with an example: a myocardial infarction (MI) occurring in a patient’s hospital trajectory of care. The patient follow-up was traced via the prospective payment system. We applied a semi-automatic text mining process to conduct a comprehensive review of patient healthcare trajectory studies. This review investigated how the concept of trajectory is defined, studied and what it achieves.MethodsWe performed a PubMed search to identify reports that had been published in peer-reviewed journals between January 1, 2000 and October 31, 2015. Fourteen search questions were formulated to guide our review. A semi-automatic text mining process based on a semantic approach was performed to conduct a comprehensive review of patient healthcare trajectory studies. Text mining techniques were used to explore the corpus in a semantic perspective in order to answer non-a priori questions. Complementary review methods on a selected subset were used to answer a priori questions.ResultsAmong the 33,514 publications initially selected for analysis, only 70 relevant articles were semi-automatically extracted and thoroughly analysed. Oncology is particularly prevalent due to its already well-established processes of care. For the trajectory thema, 80% of articles were distributed in 11 clusters. These clusters contain distinct semantic information, for example health outcomes (29%), care process (26%) and administrative and financial aspects (16%).ConclusionThis literature review highlights the recent interest in the trajectory concept. The approach is also gradually being used to monitor trajectories of care for chronic diseases such as diabetes, organ failure or coronary artery and MI trajectory of care, to improve care and reduce costs. Patient trajectory is undoubtedly an essential approach to be further explored in order to improve healthcare monitoring.
Pharmacologic Complement Inhibition in Clinical Transplantation
Authors: Tatapudi Vasishta S. , Montgomery Robert A. 
Published: April 2017

Abstract

Purpose of Review
Over the past two decades, significant strides made in our understanding of the etiology of antibody-mediated rejection (AMR) in transplantation have put the complement system in the spotlight. Here, we review recent progress made in the field of pharmacologic complement inhibition in clinical transplantation and aim to understand the impact of this therapeutic approach on outcomes in transplant recipients.

Recent Findings
Encouraged by the success of agents targeting the complement cascade in disorders of unrestrained complement activation like paroxysmal nocturnal hemoglobinuria (PNH) and atypical hemolytic uremic syndrome (aHUS), investigators are testing the safety and efficacy of pharmacologic complement blockade in mitigating allograft injury in conditions ranging from AMR to recurrent post-transplant aHUS, C3 glomerulopathies and antiphospholipid anti-body syndrome (APS). A recent prospective study demonstrated the efficacy of terminal complement inhibition with eculizumab in the prevention of acute AMR in human leukocyte antigen (HLA)-incompatible living donor renal transplant recipients. C1 esterase inhibitor (C1-INH) was well tolerated in two recent studies in the treatment of AMR and was associated with improved renal allograft function.

Summary
Pharmacologic complement inhibition is emerging as valuable therapeutic tool, especially in the management of highly sensitized renal transplant recipients. Novel and promising agents that target various elements in the complement cascade are in development.

AbstractObjectiveTo investigate the presence of previously undiagnosed radiographic bronchiectasis in stable chronic obstructive pulmonary disease (COPD) patients using high resolution computed tomography (HRCT) and to evaluate the effect of radiographic bronchiectasis on the symptoms and risks in stable COPD patients.MethodsFrom May 2012 to April 2014, there were 347 patients enrolled in COPD database. Data describing the general conditions, the frequency of acute exacerbations the year before, COPD assessment test, modified medical research council (mMRC) score, spirometric classification, and HRCT were collected. COPD patients were classified into two groups: COPD with bronchiectasis and COPD without bronchiectasis. The clinical characteristics of both groups were compared.ResultsBronchiectasis was presented in 18.4% (n = 64). The proportion of smokers, smoking index, and forced expiratory volume in 1 second predicted value were 62.5%, 27.3 ± 13.2, 48.2 ± 26.4, respectively, in the bronchiectasis group, which were lower than those of the group without bronchiectasis (82.0%, 32.6 ± 17.6, and 57.9 ± 18.8) (P < 0.05). Complications, COPD assessment test (CAT) and the rate of CAT ≥ 10 in the bronchiectasis group were 2.8 ± 1.7,13.6 ± 7.4 and 26.6%, respectively, which were higher than those of the group without bronchiectasis (2.3 ± 1.5,11.3 ± 6.0, and 11.7%) (P < 0.05). The proportion of type D (high‐risk more‐symptoms) in the bronchiectasis group was 50.0%; it was significantly higher than that of 35.7% in the group without bronchiectasis (P < 0.05).ConclusionsCOPD with bronchiectasis is associated with more complications, symptoms, and risks. More attention should be paid to the treatment of COPD with bronchiectasis to reduce the frequency of exacerbation and improve the health status.

Abstract
We present results of lithological and geochemical studies of Paleozoic deposits stripped by drilling within the Ledyanskaya area in the north of the Tunguska syneclise. The studied section has a terrigenous sulfate–carbonate composition and is complicated by trap intrusions. We have established that the Ordovician–Devonian sedimentation proceeded within an epicontinental basin, with its depth varying from supralittoral to lower sublittoral zones. In the Carboniferous and Permian, coastal-continental sedimentation was predominant; in the Late Permian it was accompanied by volcanic activity. Analysis of the poroperm properties of rocks has distinguished three potential oil reservoirs: Silurian reef carbonate deposits and Ordovician and Carboniferous sand horizons. The Lower Silurian argillaceous–carbonate rocks and Devonian carbonate–sulfate–clay members, halite beds, dolerite bodies, and tuffaceous rocks are probably confining beds of these reservoirs. Geochemical study of organic matter has shown several possible sources of hydrocarbons: Upper Proterozoic deposits, Lower and Middle Cambrian Kuonamka complex, Middle Devonian Yukta Formation, and Upper Paleozoic coal-bearing deposits.
Sex moderates the effects of positive and negative affect on clinical pain in patients with knee osteoarthritis

Abstract

Background and aims
Sex differences in clinical pain severity and response to experimental pain are commonly reported, with women generally showing greater vulnerability. Affect, including state (a single rating) and stable (average daily ratings over two weeks) positive affect and negative affect has also been found to impact pain sensitivity and severity, and research suggests that affect may modulate pain differentially as a function of sex. The current study aimed to examine sex as a moderator of the relationships between affect and pain-related outcomes among participants with knee osteoarthritis (KOA).

Methods
One hundred and seventy-nine participants (59 men) with KOA completed electronic diaries assessing clinical pain, positive affect, and negative affect. A subset of participants (n = 120) underwent quantitative sensory testing, from which a single index of central sensitization to pain was derived. We used multiple regression models to test for the interactive effects of sex and affect (positive versus negative and stable versus state) on pain-related outcomes. We used mixed effects models to test for the moderating effects of sex on the relationships between state affect and pain over time.

Results
Sex differences in affect and pain were identified, with men reporting significantly higher stable positive affect and lower central sensitization to pain indexed by quantitative sensory testing, as well as marginally lower KOA-specific clinical pain compared to women. Moreover, there was an interaction between stable positive affect and sex on KOA-specific clinical pain and average daily non-specific pain ratings. Post hoc analyses revealed that men showed trends towards an inverse relationship between stable positive affect and pain outcomes, while women showed no relationship between positive affect and pain. There was also a significant interaction between sex and stable negative affect and sex on KOA-specific pain such that men showed a significantly stronger positive relationship between stable negative affect and KOA-specific pain than women. Sex did not interact with state affect on pain outcomes.

Conclusions
Findings suggest that men may be particularly sensitive to the effects of stable positive affect and negative affect on clinical pain. Future work with larger samples is needed in order to identify potential mechanisms driving the sex-specific effects of affect on pain.

Implications
The current study provides novel data that suggesting that the association of positive affect, negative affect, and pain are different in men versus women with KOA. Further understanding of the difference in affective expression between men and women may lead to the development of novel therapeutic interventions and help to identify additional modifiable factors in the prevention and management of pain.

Published: April 2017

Objective The purpose of the present study is to compare several models of commercially designed belts as used as a tourniquet. Methods In the Belts Evaluated as Limb Tourniquets (BELT) study, an experiment was designed to test the effectiveness of pants belts as nonimprovised medical devices to control hemorrhage in a manikin. Models of belts included Tourni-belt, Tourniquet Belt, ParaBelt, and Battle Buddy. Data collected included effectiveness, time to stop bleeding, total time of application, pressure, blood loss, and composite results (score count of good results; composite outcome good if every component was good). Results Differences in effectiveness percentages among models were not statistically significant. The difference in mean between users was statistically significant for stop time, total time, pressure, blood loss, composite score, and composite outcome. Mean time to stop bleeding differed for only 1 pair of models after the Tukey-Kramer adjustment; ParaBelt was faster than Tourniquet Belt. Mean total time of application differed between ParaBelt–Tourniquet Belt and Tourni-belt–Tourniquet Belt; the former model in both pairs was faster. No significant difference in mean blood loss measured by model was found. For composite outcome score, no pairwise difference between models was significant. For composite outcome (good-bad), ParaBelt had good results in 75% of tests; the other 3 models had significantly worse results. Conclusions In a preliminary laboratory analysis of belt tourniquet models using a manikin, performance differed by model. ParaBelt performed better than other models for the composite outcome.
Impact of a multifaceted antimicrobial stewardship program: A front-line ownership driven quality improvement project in a large urban emergency department
Authors: Kaufman Adam Jonathan , McCready Janine , Powis Jeff 
Published: April 2017

AbstractBackgroundAntibiotic overuse has promoted growing rates of antimicrobial resistance and secondary antibiotic-associated infections such asClostridium difficile(C. difficile). Antimicrobial stewardship programs (ASPs) are effective in reducing antimicrobial use in the inpatient setting; however, the unique environment of the emergency department (ED) lends itself to challenges for successful implementation. Front-line ownership (FLO) methodology has been shown to be a potentially effective strategy for the implementation of inpatient ASPs through an iterative multi-pronged approach driven by front-line providers.ObjectiveTo determine whether a FLO approach to antimicrobial stewardship in the ED can alter antimicrobial usage.MethodsInterventions were driven by ED physicians and facilitated by Infectious Diseases Division physicians from the hospital’s ASP using FLO principles. Measured end points included antibiotic usage in the ED as measured by defined daily doses, and rates of urine culture sent from the ED.ResultsThere was a step-wise significant reduction in the use of azithromycin (p=0.006), ceftriaxone (p=0.045), ciprofloxacin (p=0.034), and moxifloxacin (p=0.008). There was also a significant reduction in rates of urine cultures (p&lt;0.001) by 2.26 urine cultures per 100 ED patient visits.ConclusionsFLO offers a promising approach to successful implementation of an ASP in the ED. Future studies would be important to evaluate the generalizability of the FLO approach to ASP development in other EDs and to determine strategies to improve the sustainability of reductions in antimicrobial use.
A Novel Twist to Tocqueville: Competing Visions of Democracy inParrot and Olivier in America
Authors: Johnson Joel 
Published: April 2017

AbstractPeter Carey'sParrot and Olivier in Americais a fictionalized version of Tocqueville's travels through the young United States. Unlike Tocqueville, Olivier de Garmont is accompanied by Parrot Larrit, an English servant who offers a bold egalitarian counterpoint to Olivier's aristocratic liberalism. This article compares Carey's work with Tocqueville's on the consequences of democracy for political institutions, education, and art; discusses Carey's technique of using alternating narration between Olivier and Parrot to capture the complexities of American democracy; and concludes with thoughts about being a friendly critic of democracy in the twenty-first century. AlthoughParrot and Olivieris no substitute forDemocracy in America, it addresses Tocqueville's concerns in a creative and subtle manner, prompting reflection on whether—to use Olivier's terms—democracy has “ripened well.”
Parent–child intervention decreases stress and increases maternal brain activity and connectivity during own baby-cry: An exploratory study

Published: April 2017

AbstractParental responses to their children are crucially influenced by stress. However, brain-based mechanistic understanding of the adverse effects of parenting stress and benefits of therapeutic interventions is lacking. We studied maternal brain responses to salient child signals as a function of Mom Power (MP), an attachment-based parenting intervention established to decrease maternal distress. Twenty-nine mothers underwent two functional magnetic resonance imaging brain scans during a baby-cry task designed to solicit maternal responses to child's or self's distress signals. Between scans, mothers were pseudorandomly assigned to either MP (n = 14) or control (n = 15) with groups balanced for depression. Compared to control, MP decreased parenting stress and increased child-focused responses in social brain areas highlighted by the precuneus and its functional connectivity with subgenual anterior cingulate cortex, which are key components of reflective self-awareness and decision-making neurocircuitry. Furthermore, over 13 weeks, reduction in parenting stress was related to increasing child- versus self-focused baby-cry responses in amygdala–temporal pole functional connectivity, which may mediate maternal ability to take her child's perspective. Although replication in larger samples is needed, the results of this first parental-brain intervention study demonstrate robust stress-related brain circuits for maternal care that can be modulated by psychotherapy.

Published: April 2017

AbstractStudies 1 and 2 investigated how maternal severe mental illness (SMI) related to mothers’ mind–mindedness (appropriate and nonattuned mind-related comments). Study 1 showed that mothers with SMI (n= 50) scored lower than psychologically well mothers for both appropriate and nonattuned comments, whereas mothers with SMI in Study 2 (n= 22) had elevated levels of nonattuned comments. Study 2 also tested the efficacy of a single-session video-feedback intervention to facilitate mind–mindedness in mothers with SMI. The intervention was associated with a decrease in nonattuned comments, such that on discharge, mothers did not differ from psychologically well controls. Study 3 assessed infant–mother attachment security in a small subset of intervention-group mothers from Study 2 (n= 9) and a separate group of standard care mothers (n= 30) at infant mean age 17.1 months (SD= 2.1). Infants whose mothers completed the intervention were more likely to be securely attached and less likely to be classified as insecure–disorganized than those of mothers who received standard care. We conclude that a single session of video-feedback to facilitate mind–mindedness in mothers with SMI may have benefits for mother–infant interaction into the second year of life.

Published: April 2017

SummaryCooling techniques have several applications for reproduction in aquaculture. However, few studies have sought to create protocols for cooling and cryopreservation ofMacrobrachium amazonicumembryos. Thus, the objective of this work was to verify the survival ofM. amazonicumembryos and the correlation between embryonic volume and mortality ofM. amazonicumembryos after cooling. Embryo pools were collected from three females and divided into two treatment groups: dimethyl sulfoxide (DMSO) 3% and ethylene glycol (EG) 0.5%, both of them associated with 2 M sucrose. Positive and negative control groups consisted of seawater 10%. Aliquots of 10 µg of embryos were placed in Falcon®tubes containing a cryoprotectant solution and submitted directly to the test temperature of 2°C for 2 and 6 h of cooling. Further analysis of survival and embryonic volume were performed under a stereoscopic microscope. Data were subjected to analysis of variance (ANOVA), and means were compared using the Tukey test at 5%. The highest embryonic survival rate was observed after the shortest storage time for both the DMSO 3% and the 0.5% EG groups, with survival rates of 84.8 ± 3.9 and 79.7 ± 2.8%, respectively. There was a reduction in survival after 24 h, with the DMSO 3% group presenting a survival rate of 71.7 ± 6.6%, and the EG 0.5% group, 66 ± 6.9%. Survival showed a statistically significant difference when compared with the positive controls after 2 h and 24 h of cooling, with 99 ± 0.5% and 95.8 ± 1.5% survival rates, respectively. There was no significant statistical difference in the embryonic volume, but it was possible to observe a change in the appearance of the embryos, from a translucent coloration to an opaque white or brownish coloration, after 24 h in incubators. Thus, it can be concluded that survival is inversely proportional to storage time and that, although there was no change in the embryonic volume after cooling, a change in the appearance of embryos could be observed.

Published: April 2017

AbstractObjectives:The negative effect of changes in social behavior following traumatic brain injury (TBI) are known, but much less is known about the neuropsychological impairments that may underlie and predict these changes. The current study investigated possible associations between post-injury behavior and neuropsychological competencies of emotion recognition, understanding intentions, and response selection, that have been proposed as important for social functioning.Methods:Forty participants with TBI and 32 matched healthy participants completed a battery of tests assessing the three functions of interest. In addition, self- and proxy reports of pre- and post-injury behavior, mood, and community integration were collected.Results:The TBI group performed significantly poorer than the comparison group on all tasks of emotion recognition, understanding intention, and on one task of response selection. Ratings of current behavior suggested significant changes in the TBI group relative to before the injury and showed significantly poorer community integration and interpersonal behavior than the comparison group. Of the three functions considered, emotion recognition was associated with both post-injury behavior and community integration and this association could not be fully explained by injury severity, time since injury, or education.Conclusions:The current study confirmed earlier findings of associations between emotion recognition and post-TBI behavior, providing partial evidence for models proposing emotion recognition as one of the pre-requisites for adequate social functioning.
