Objective: Ulcerative colitis (UC) may be characterized by metal ion and antioxidant deficiencies. Raphacol bile granule (containing vitamin A, E, C, polyphenols and isothiocyanates) supplementary treatment was applied in moderately active UC patients to estimate its effect on the element status. Materials and methods: Element content (Al, Ca, Cu, Fe, Mg, Mn, P, S and Zn) in erythrocyte of 15 Caucasian volunteers, 25 moderately UC patients with therapy recommended by WHO and 25 patients treated with Raphacol bile granule (0.2 g/d for 6 months) were studied with ICP-AES. Results and conclusions: Significantly decreased Ca, Fe and Zn concentrations were found in erythrocyte of UC patients (24.38 ± 11.00, 415.0 ± 87.6, 10.86 ± 4.37 μmol/l, respectively) compared to controls (69.25 ± 21.00, 535.5 ± 69.1, 16.67 ± 3.34 μmol/l, respectively). After 6- month isothiocyanate treatment, the Cu (0.551 ± 0.380 μmol/l), Fe (534.6 ± 23.1 μmol/1), Mg (63.41 ± 11.19 μmol/l) and P (1,089.0 ± 104.2 μmol/l) content in erythrocyte increased significantly. Summarizing the small amount of Raphacol treatment for 6 months alters the element status in moderately active UC. The favorable effect may be connected to the local antioxidant effect of the bioactive agents which may contribute to the increased element absorption. [ABSTRACT FROM AUTHOR]

Oxidative damage connected with ischemia reperfusion occurs during liver resection and transplantation. The aim was to elucidate the correlation between alterations of the redox defensive system and metal element concentrations in ischemia reperfusion injury. Wistar rats were divided into 4 groups: control, sham-operated, ischemic and reperfusion groups. Hepatic ischemia was induced for 45 min followed by 15 min of reperfusion. Chemiluminescent intensity, H-donating ability, reducing power, SH group concentration, total antioxidant status, glutathione peroxidase and superoxide dismutase activity were detected by luminometry and spectrophotometry. Blood parameters (Hitachi 717 Analyzer) as well as Ca, Cu, Fe, Mg, Mn, P, S and Zn concentrations of liver with ICP-OES were also determined. Se content was determined by a cathodic stripping voltametric method. H-donating ability and reducing power decreased and glutathione peroxidase level of the liver were significantly lower during reperfusion than in the sham-operated group. The same tendency could be observed in the level of superoxide dismutase. The changes in the metal element concentration are essential for cellular pathways, for example, significant decrease in Cu, Zn, Mn and Se content may serve as an explanation for decreased glutathione peroxidase and superoxide dismutase activities. Changes in Ca, Mg, P and S concentrations during ischemia reperfusion processes also show the important role of these elements in the tissue regeneration. Significant disturbance of the antioxidant balance could be detected, which was related to the alterations of metal element concentration in the liver tissue. [ABSTRACT FROM AUTHOR]

AbstractCrown-of-thorns sea stars ( Acanthaster sp.) are among the most studied coral reef organisms, owing to their propensity to undergo major population irruptions, which contribute to significant coral loss and reef degradation throughout the Indo-Pacific. However, there are still important knowledge gaps pertaining to the biology, ecology, and management of Acanthaster sp. Renewed efforts to advance understanding and management of Pacific crown-of-thorns sea stars ( Acanthaster sp.) on Australia's Great Barrier Reef require explicit consideration of relevant and tractable knowledge gaps. Drawing on established horizon scanning methodologies, this study identified contemporary knowledge gaps by asking active and/or established crown-of-thorns sea star researchers to pose critical research questions that they believe should be addressed to improve the understanding and management of crown-of-thorns sea stars on the Great Barrier Reef. A total of 38 participants proposed 246 independent research questions, organized into 7 themes: feeding ecology, demography, distribution and abundance, predation, settlement, management, and environmental change. Questions were further assigned to 48 specific topics nested within the 7 themes. During this process, redundant questions were removed, which reduced the total number of distinct research questions to 172. Research questions posed were mostly related to themes of demography (46 questions) and management (48 questions). The dominant topics, meanwhile, were the incidence of population irruptions (16 questions), feeding ecology of larval sea stars (15 questions), effects of elevated water temperature on crown-of-thorns sea stars (13 questions), and predation on juveniles (12 questions). While the breadth of questions suggests that there is considerable research needed to improve understanding and management of crown-of-thorns sea stars on the Great Barrier Reef, the predominance of certain themes and topics suggests a major focus for new research while also providing a roadmap to guide future research efforts.

Importance: Health care and government organizations call for routine collection of sexual orientation and gender identity (SOGI) information in the clinical setting, yet patient preferences for collection methods remain unknown., Objective: To assess of the optimal patient-centered approach for SOGI collection in the emergency department (ED) setting., Design, Setting, and Participants: This matched cohort study (Emergency Department Query for Patient-Centered Approaches to Sexual Orientation and Gender Identity [EQUALITY] Study) of 4 EDs on the east coast of the United States sequentially tested 2 different SOGI collection approaches between February 2016 and March 2017. Multivariable ordered logistic regression was used to assess whether either SOGI collection method was associated with higher patient satisfaction with their ED experience. Eligible adults older than 18 years who identified as a sexual or gender minority (SGM) were enrolled and then matched 1 to 1 by age (aged ≥5 years) and illness severity (Emergency Severity Index score ±1) to patients who identified as heterosexual and cisgender (non-SGM), and to patients whose SOGI information was missing (blank field). Patients who identified as SGM, non-SGM, or had a blank field were invited to complete surveys about their ED visit. Data analysis was conducted from April 2017 to November 2017., Interventions: Two SOGI collection approaches were tested: nurse verbal collection during the clinical encounter vs nonverbal collection during patient registration. The ED physicians, physician assistants, nurses, and registrars received education and training on sexual or gender minority health disparities and terminology prior to and throughout the intervention period., Main Outcomes and Measures: A detailed survey, developed with input of a stakeholder advisory board, which included a modified Communication Climate Assessment Toolkit score and additional patient satisfaction measures., Results: A total of 540 enrolled patients were analyzed; the mean age was 36.4 years and 66.5% of those who identified their gender were female. Sexual or gender minority patients had significantly better Communication Climate Assessment Toolkit scores with nonverbal registrar form collection compared with nurse verbal collection (mean [SD], 95.6 [11.9] vs 89.5 [20.5]; P = .03). No significant differences between the 2 approaches were found among non-SGM patients (mean [SD], 91.8 [18.9] vs 93.2 [13.6]; P = .59) or those with a blank field (92.7 [15.9] vs 93.6 [14.7]; P = .70). After adjusting for age, race, illness severity, and site, SGM patients had 2.57 (95% CI, 1.13-5.82) increased odds of a better Communication Climate Assessment Toolkit score category during form collection compared with verbal collection., Conclusions and Relevance: Sexual or gender minority patients reported greater comfort and improved communication when SOGI was collected via nonverbal self-report. Registrar form collection was the optimal patient-centered method for collecting SOGI information in the ED.

Background: Understanding the relative risks of maintenance treatment versus discontinuation of antipsychotics following remission in first episode psychosis (FEP) is an important area of practice., Method: A systematic review and meta-analysis. Prospective experimental studies including a parallel control group were identified to compare maintenance antipsychotic treatment with total discontinuation or medication discontinuation strategies following remission in FEP., Results: Seven studies were included. Relapse rates were higher in the discontinuation group (53%; 95% CIs: 39%, 68%; N = 290) compared with maintenance treatment group (19%; 95% CIs: 0.05%, 37%; N = 230). In subgroup analyses, risk difference of relapse was lower in studies with a longer follow-up period, a targeted discontinuation strategy, a higher relapse threshold, a larger sample size, and samples with patients excluded for drug or alcohol dependency. Insufficient studies included psychosocial functioning outcomes for a meta-analysis., Conclusions: There is a higher risk of relapse for those who undergo total or targeted discontinuation strategies compared with maintenance antipsychotics in FEP samples. The effect size is moderate and the risk difference is lower in trials of targeted discontinuation strategies., Declaration of Interest: A.T. has received honoraria and support from Janssen-Cilag and Otsuka Pharmaceuticals for meetings and has been has been an investigator on unrestricted investigator-initiated trials funded by AstraZeneca and Janssen-Cilag.

Importance: The Institute of Medicine and The Joint Commission recommend routine documentation of patients' sexual orientation in health care settings. Currently, very few health care systems collect these data since patient preferences and health care professionals' support regarding collection of data about patient sexual orientation are unknown., Objective: To identify the optimal patient-centered approach to collect sexual orientation data in the emergency department (ED) in the Emergency Department Query for Patient-Centered Approaches to Sexual Orientation and Gender Identity study., Design, Setting, and Participants: An exploratory, sequential, mixed-methods design was used first to evaluate qualitative interviews conducted in the Baltimore, Maryland, and Washington, DC, areas. Fifty-three patients and 26 health care professionals participated in the qualitative interviews. Interviews were followed by a national online survey, in which 1516 (potential) patients (244 lesbian, 289 gay, 179 bisexual, and 804 straight) and 429 ED health care professionals (209 physicians and 220 nurses) participated. Survey participants were recruited using random digit dialing and address-based sampling techniques., Main Outcomes and Measures: Qualitative interviews were used to obtain the perspectives of patients and health care professionals on sexual orientation data collection, and a quantitative survey was used to gauge patients' and health care professionals' willingness to provide or obtain sexual orientation information., Results: Mean (SD) age of patient and clinician participants was 49 (16.4) and 51 (9.4) years, respectively. Qualitative interviews suggested that patients were less likely to refuse to provide sexual orientation than providers expected. Nationally, 154 patients (10.3%) reported that they would refuse to provide sexual orientation; however, 333 (77.8%) of all clinicians thought patients would refuse to provide sexual orientation. After adjustment for demographic characteristics, only bisexual patients had increased odds of refusing to provide sexual orientation compared with heterosexual patients (odds ratio, 2.40; 95% CI, 1.26-4.56)., Conclusions and Relevance: Patients and health care professionals have discordant views on routine collection of data on sexual orientation. A minority of patients would refuse to provide sexual orientation. Implementation of a standardized, patient-centered approach for routine collection of sexual orientation data is required on a national scale to help to identify and address health disparities among lesbian, gay, and bisexual populations.

Purpose: To identify patient and provider perspectives concerning collection of sexual orientation and gender identity (SO&GI) information in emergency departments (EDs)., Methods: Semistructured interviews were conducted during the period of 2014-2015 with a diverse purposive sample of patients across the spectrum of sexual orientation and gender identities (n = 53) and ED nurses, physician assistants, physicians, and registrars (n = 38) in a major metropolitan area. Interviews were recorded, transcribed verbatim, and analyzed by multiple coders using constant comparative methods., Results: Patients were willing to provide SO&GI information if collected safely and appropriately, and staff described willingness to collect SO&GI information to inform understanding of health disparities. Key themes across respondents were as follows: What will be done with the data? How will it be collected? Who will collect it? Is the environment conducive to safe disclosure? Confidentiality and potential sensitivity; standardized collection emphasizing population health; nurse intake and/or nonverbal data collection; and environmental cues and cultural competency promoting comfort for sexual and gender minorities emerged as critical considerations for effective implementation., Conclusion: Staff and patients are amenable to SO&GI data collection in EDs, but data quality and patient and provider comfort may be compromised without attention to specific implementation considerations.

Although historically the majority of overdose education and naloxone distribution (OEND) programs have targeted opioid users, states are increasingly passing laws that enable third-party prescriptions of naloxone to individuals who may be able to respond to an overdose, including friends and family members of individuals who use opioids. In this report, we discuss the Baltimore Student Harm Reduction Coalition (BSHRC) OEND program, Maryland's first community-based, state-authorized training program under a new law allowing third-party naloxone prescription. In an 8-month pilot period, 250 free naloxone kits were distributed, and 3 overdose reversals were reported to BSHRC. Trainings were effective in increasing self-efficacy surrounding overdose prevention and response, which appears to persist at up to 12 months following the training.

Objectives: To develop a decision support system (DSS), myGRaCE, that integrates service user (SU) and practitioner expertise about mental health and associated risks of suicide, self-harm, harm to others, self-neglect, and vulnerability. The intention is to help SUs assess and manage their own mental health collaboratively with practitioners., Methods: An iterative process involving interviews, focus groups, and agile software development with 115 SUs, to elicit and implement myGRaCE requirements., Results: Findings highlight shared understanding of mental health risk between SUs and practitioners that can be integrated within a single model. However, important differences were revealed in SUs' preferred process of assessing risks and safety, which are reflected in the distinctive interface, navigation, tool functionality and language developed for myGRaCE. A challenge was how to provide flexible access without overwhelming and confusing users., Conclusion: The methods show that practitioner expertise can be reformulated in a format that simultaneously captures SU expertise, to provide a tool highly valued by SUs. A stepped process adds necessary structure to the assessment, each step with its own feedback and guidance., Practice Implications: The GRiST web-based DSS (www.egrist.org) links and integrates myGRaCE self-assessments with GRiST practitioner assessments for supporting collaborative and self-managed healthcare., (Copyright © 2015.

Objectives: To disentangle the effects of physician gender and patient-centered communication style on patients' oral engagement in depression care., Methods: Physician gender, physician race and communication style (high patient-centered (HPC) and low patient-centered (LPC)) were manipulated and presented as videotaped actors within a computer simulated medical visit to assess effects on analogue patient (AP) verbal responsiveness and care ratings. 307 APs (56% female; 70% African American) were randomly assigned to conditions and instructed to verbally respond to depression-related questions and indicate willingness to continue care. Disclosures were coded using Roter Interaction Analysis System (RIAS)., Results: Both male and female APs talked more overall and conveyed more psychosocial and emotional talk to HPC gender discordant doctors (all p<.05). APs were more willing to continue treatment with gender-discordant HPC physicians (p<.05). No effects were evident in the LPC condition., Conclusions: Findings highlight a role for physician gender when considering active patient engagement in patient-centered depression care. This pattern suggests that there may be largely under-appreciated and consequential effects associated with patient expectations in regard to physician gender that these differ by patient gender., Practice Implications: High patient-centeredness increases active patient engagement in depression care especially in gender discordant dyads., (Copyright © 2014 Elsevier Ireland Ltd.

The suspected endocrine disruptor bisphenol A (BPA) is associated with the manufacture, distribution, and use of epoxy resins and polycarbonate plastics; thus, studies of this compound have focused primarily on urban areas in developed countries. This small study investigating urinary BPA of 109 people was conducted in the urban United States, urban Jamaica, and rural Ghana. Additionally, local drinking and surface water samples were collected and analyzed from areas near study participants. Levels of BPA in both urine and water were comparable among all three sites. Thus, future studies of BPA should consider expanding investigations to rural areas not typically associated with the compound.

Aim To explore current risk assessment processes in general practice and Improving Access to Psychological Therapies (IAPT) services, and to consider whether the Galatean Risk and Safety Tool (GRiST) can help support improved patient care.Background Much has been written about risk assessment practice in secondary mental health care, but little is known about how it is undertaken at the beginning of patients' care pathways, within general practice and IAPT services.Methods Interviews with eight general practice and eight IAPT clinicians from two primary care trusts in the West Midlands, UK, and eight service users from the same region. Interviews explored current practice and participants' views and experiences of mental health risk assessment. Two focus groups were also carried out, one with general practice and one with IAPT clinicians, to review interview findings and to elicit views about GRiST from a demonstration of its functionality. Data were analysed using thematic analysis.Findings Variable approaches to mental health risk assessment were observed. Clinicians were anxious that important risk information was being missed, and risk communication was undermined. Patients felt uninvolved in the process, and both clinicians and patients expressed anxiety about risk assessment skills. Clinicians were positive about the potential for GRiST to provide solutions to these problems.Conclusions A more structured and systematic approach to risk assessment in general practice and IAPT services is needed, to ensure important risk information is captured and communicated across the care pathway. GRiST has the functionality to support this aspect of practice.

Objective: To explore how experienced clinicians from wide ranging specialities deliver bad news, and to investigate the relationship between physician characteristics and patient centredness., Methods: Consultations involving 46 hospital consultants from 22 different specialties were coded using the Roter Interaction Analysis System., Results: Consultants mainly focussed upon providing biomedical information and did not discuss lifestyle and psychosocial issues frequently. Doctor gender, age, place of qualification, and speciality were not significantly related to patient centredness., Conclusion: Hospital consultants from wide ranging specialities tend to adopt a disease-centred approach when delivering bad news. Consultant characteristics had little impact upon patient centredness. Further large-scale studies are needed to examine the effect of doctor characteristics on behaviour during breaking bad news consultations., Practice Implications: It is possible to observe breaking bad news encounters by video-recording interactions between clinicians and simulated patients. Future training programmes should focus on increasing patient-centred behaviours which include actively involving patients in the consultation, initiating psychosocial discussion, and providing patients with opportunities to ask questions., (Copyright © 2010 Elsevier Ireland Ltd.

Aim: To explore the experiences of healthcare assistants (HCAs) working in general practice (GP)., Background: HCAs increasingly play an important role in UK GP teams. The role is relatively new and little is known about how HCAs feel about their work in GP, and the challenges that they face., Methods: Semi-structured interviews were undertaken with 14 HCAs from two Primary Care Trusts in the West Midlands, United Kingdom. Transcriptions were analysed using the framework analysis approach., Findings: Overall, HCAs reported that they enjoyed their work, and particularly appreciated the patient contact and positive feedback gained. Attitudes to the role were affected by previous position, experience, and length of time working within the practice. The HCAs felt accepted and supported by GP team members and valued the support they were receiving. Key sources of frustration included the poor salary, the lack of initial clarity with regard to role definition, and the constraints of their scope of practice. Role boundaries between HCAs and practice nurses were experienced as well defined, and no perceptions of role ambiguity were reported. HCAs considered their work to be of relatively low status, with its main purpose being to ease the practice nurse's workload. Although many had the desire to train as nurses, few saw it as a realistic possibility., Conclusions: Although HCAs appear to be satisfied overall, the elements of dissatisfaction relate to status, pay, and career progression, which may limit the retention of individuals in this role. Practices should consider the importance of recognising and valuing the work of HCAs and of providing protected time and resources for mentorship and career progression.

Objective: This study compared the methylphenidate (MPH) dose-response profiles of children with the Predominantly Inattentive (PI) and Combined (CB) subtypes of attention-deficit/hyperactivity disorder (ADHD). It is the first such study to enroll a sample comprised exclusively of children, all but one of whom had no prior exposure to ADHD medications., Method: The design was a double-blind crossover with 1-week exposures to placebo and low, medium, and high, fixed, three times daily (t.i.d.) dosage regimens of immediate-release MPH, administered in random order. Parents and teachers completed weekly behavioral questionnaires (Conners, Swanson, Kotkin, Agler, M-Flynn and Pelham Scale [SKAMP]) and a child psychiatrist provided weekly ratings of symptom severity (ADHD Rating Scale [ADHD-RS]), side effects (Side Effects Rating Scale), and a Clinical Global Impressions-Severity (CGI-S). In addition, laboratory measures of vigilance (Continuous Performance Test [CPT]) and resistance to cognitive interference (Stroop) were administered weekly., Results: Twenty-five children (15 CB, 10 PI), who met rigorous diagnostic criteria for their ADHD subtype, completed the study. Groups did not differ on demographic variables or severity at baseline. Behavioral questionnaires and clinical ratings indicated significant improvement on MPH for both subtypes but no differences in response profiles of the two groups. Drug effects were predominantly linear for both subtypes. Effects of MPH were significant for the CPT, but not the Stroop, instrument with no differences between ADHD subtypes., Conclusions: Results support the clinical utility of MPH in the treatment of the PI subtype and provide no evidence of differences in response between the subtypes.

The Predominantly Inattentive (PI) and Combined (CB) subtypes of AD/HD differ in cognitive tempo, age of onset, gender ratio, and comorbidity, yet a differentiating endophenotype has not been identified. The aim of this study was to test rigorously diagnosed PI, CB, and typical children on measures selected for their potential to reveal hypothesized differences between the subtypes in specific neurocognitive systems (anterior vs. posterior attentional systems) and processes (arousal vs. activation). Thirty-four CB and 26 PI children meeting full DSM-IV criteria for subtype both in school and at home, without confounding reading disability or emotional disorder, were enrolled along with 20 typically developing children. Neurocognitive functions measured included attention, inhibitory control, working memory, learning, and executive functions. Tasks included the Stroop, Wisconsin Card Sorting Test, Continuous Performance Test (CPT). Buschke Selective Reminding Test, ad the Tower of London (TOL), as well as instruments developed by Posner and Sternberg, and tasks assessing the impact on reaction time of [corrected] varying preparatory intervals and stimulus/response complexity. After co-varying for IQ, subtypes differed primarily on measures of impulsivity during tests of vigilance (CPT) and executive function (TOL), with the CB group showing greater impulsivity than both other groups. In addition, the PI group showed worse performance than CB and control groups on the WISC-III Processing Speed Index. Whether analyzed with or without an IQ co-variate, there was no support in the data for hypothesized differences between subtypes in functioning of the anterior vs. posterior attentional systems, nor in involvement of arousal vs. activation processes. The results indicate that the PI and CB subtypes are best differentiated by ratings, observations and tests of cognitive tempo and behavioral impulsivity. Neuropsychological methods have yet to identify critical neuropsychological [corrected] substrates of these differences.
